    Full Text Available Pedanius Dioscorides was a Roman army surgeon in the first century A.D. His great work called De Materia Medica is widely accepted as the foremost pharmaceutical source of antiquity. Dioscorides was the originator of materia medica (pharmacology, and he took advantage of his extensive travels to study plants. Dioscorides was considered a major authority on simple drugs for sixteen centuries. De Materia Medica served as a corner stone for both western and eastern pharmaceutical and herbal writing, and was translated into Syriac, Arabic, and Persian, as well as Latin. The particular characteristic of medical therapy in the Medieval Period was the extensive employment of drugs of all kinds. For this reason, Dioscorides’ De Materia Medicawas not only studied closely, but it also became a text book that Turk-Islamic scientists frequently referred to in their writings.Pedanius Dioscórides fue médico cirujano en el ejército romano en el siglo I d.C. Su gran obra llamada De Materia Medica es conocida como la principal fuente de farmacopea de la antigüedad. Dioscórides fue el inventor de la materia medica, y aprovechó sus extensos viajes para dedicarse al estudio de las plantas. Dioscórides fue considerado una eminencia en el tema de las drogas de origen natural a lo largo de dieciséis siglos. De Materia Medica sirvió como piedra angular para los textos farmacéuticos y herbarios tanto en occidente como en oriente y fue traducida al siríaco, árabe y persa, además de al latín. La particular característica de la terapia médica en la época medieval fue el uso extensivo de todo tipo de drogas. Por esta razón, además de estudiarse minuciosamente, De Materia Medica de Dioscórides se convirtió también en un libro de texto al que frecuentemente hacían referencia los científicos turco-islámicos en sus escrituras.

    According to archaeological discoveries, humans began to make use of marine natural resources early in the Palaeolithic era. In the Spring and Autumn period and Warring States period, they began to use marine life as medicines and also had simple cognitions on their efficacy and processing. In the Qin and Han dynasties, people further deepened the understanding of the marine Chinese materia medica and created prescriptions making use of marine drugs. In the Tang and Song period, the number of marine Chinese materia medica species and corresponding prescriptions apparently increased. The cognitions of the property, flavor, efficacy as well as the compatible principle of marine Chinese materia medica was further deepened and the scope of their treatment also significantly expanded. In the Ming and Qing dynasties, the cognition of the marine Chinese materia medica was mainly the conclusions of the previous experience. After the founding of the People's Republic of China (PRC), with the development of science and technologies, the ability of exploiting and utilizing the marine Chinese materia medica by people dramatically increased, and the species of marine Chinese materia medica reached more than one thousand. However, the development of marine Chinese materia medica is confronted with new problems; although the number of species of marine Chinese materia medica increased, the understanding of their property and flavor is obviously lagging behind, which seriously affects the clinical application of marine Chinese materia medica.

    Using Chinese Materia Medica (CM) as injections is an innovation that is proving effective in extensive clinical use in Mainland China. However, recent reports have focused on adverse reactions, ignoring the considerable successes of these preparations. In order to achieve balance in the media and in the minds of the public, we suggest the first step is to clarify the concepts of and differences between adverse drug reactions (ADR) and adverse events (AE) for all concerned-the public, medical practitioners, government officials, and lawmakers. Second, the State Food and Drug Administration should raise the requirements for Chinese Materia Medica Injection (CMI) registration and license approval and emphasize the importance of evidence-based CMI development and evidence-based CMI license approval. Thirdly, drug companies and institutions should reinforce basic research about the quality control of herbs and CMI-drug interactions. Fourth, the Government should clarify the legal responsibilities for CMI approval agencies, CMI developers, medical doctors, and patients. Fifth, the medical association and Government should enhance training for health care professionals concerning the usage of CMIs. And finally sixth, State Food and Drug Administration should monitor the content and quality of the directions for use of CMI. © 2010 Blackwell Publishing Asia Pty Ltd and Chinese Cochrane Center, West China Hospital of Sichuan University.

    Standards of commodity classes of Chinese materia medica is an important way to solve the "Lemons Problem" of traditional Chinese medicine market. Standards of commodity classes are also helpful to rebuild market mechanisms for "high price for good quality". The previous edition of commodity classes standards of Chinese materia medica was made 30 years ago. It is no longer adapted to the market demand. This article researched progress on standards of commodity classes of Chinese materia medica. It considered that biological activity is a better choice than chemical constituents for standards of commodity classes of Chinese materia medica. It is also considered that the key point to set standards of commodity classes is finding the influencing factors between "good quality" and "bad quality". The article also discussed the range of commodity classes of Chinese materia medica, and how to coordinate standards of pharmacopoeia and commodity classes. According to different demands, diversiform standards can be used in commodity classes of Chinese materia medica, but efficacy is considered the most important index of commodity standard. Decoction pieces can be included in standards of commodity classes of Chinese materia medica. The authors also formulated the standards of commodity classes of Notoginseng Radix as an example, and hope this study can make a positive and promotion effect on traditional Chinese medicine market related research.

    By Zhuang materia medica, it refers to application of medicines under the instructions of medical theory of Zhuang ethnic group. By studying the pronunciation of the Zhuang language for the terms "zhu yu", "bai jiu", and "mi gu" included in the shan hai jing nan shan jing (The Classic of Southern Mountain in Classic of Seas and Mountains) carried out by the Zhuang scholar Qin Bao-lin, it was concluded that the Zhuang minority already applied medicines early in the pre-Qin period. Through extensive cultural communication in different regions in the Wei-Jin-Southern-Northern Dynasties, the medicinal experiences of the Zhuang ethnic group appeared in ancient literature. The antidotes in Zhou hou fang (Handbook of Prescriptions for Emergency), for instance, were mostly coming from the Southern Ridge area. Since the Sui-Tang Dynasties, many materia medica recorded in the herbal works and regional gazetteers, and Annals such as the Guangxi Annals, Gazetteer of Nanning County, and Gazetteer of Liuzhou County, Gazetteer of Binzhou County etc., also carry medicines such as Cinnamom twigs and bark, and mangosteen etc., which are similar to those of the Zhuang medicines. In the Republican period, many manuscripts of Zhuang medicines appeared. After 1949, many institutions of Zhuang medicine were set up successively, including The Nanning Medical Institute, The Medical Institute of Wuzhou, The Medical Institute of Guilin. Systematic researches were also done, with publication of a series of works on Zhuang materia medica. Reformation of part of the prescription forms of Zhuang medicine were also accomplished.

    Shennong Bencaojing was orignally recorded in Qi Lu of the Liang Dynasty and Tangye Jingfa (about prescriptions) was originally recorded in Hanshu Yiwenzhi. According to the norm of the development of knowledge, knowledge about medical herbs should have been formed before that of prescriptions. In accordance with literature, Tangye Jingifa is recorded in QI Lue of the Western Han Dynasty, which was compiled much earlier than Shennong Bencaojing. So where was the knowledge about herbs recorded in the Western Han Dynasty and before? It was found after textual research that knowledge about medical herbs was recorded together with prescriptions long before the Han Dynasty. In the Western Han Dynasty, Liu Xiang and his colleagues placed herbs under the catalogue of prescriptions when they proofread books. In the Eastern Han Dynasty, materia medica became a single category due to the need to compose prescriptions according to syndrome differentiation and the standardization of herbal administration.

    2012-12-01

    The heritage of medicine is written in many forms. One repository is to be found in the history of orchids, the world's largest family of flowering plants. Orchids were so named by Theophrastus (c.372-288 BC) who recorded their medicinal use as an aphrodisiac and the promoter of virility, in the context of the Doctrine of Signatures. Such use endured for millennia, and was recorded both by Paracelsus (1493-1551) and Linnaeus (1707-1778). The history of orchidology and medicine are entwined in four domains: (a) orchids and their historical materia medica, within the paradigm of the Doctrine of Signatures; (b) the enduring and extensive contemporary medicinal and culinary use of orchids such as Vanilla and salep extracts of Orchis; (c) the scientific contributions of doctors as orchidologists; and (d) the heritage of more than a hundred doctors' names in the scientific etymology of the Orchidaceae family. Prominent orchidologists have included the Scottish doctor-soldier and botanist, Robert Brown (1773-1858); the Director of the State Herbarium at Leyden and the Rijks Museum, Carl Ludwig Blume (1796-1862); and Dr William Sterling MD (1888-1967). Among the more than 1250 genus names (and 33,000 species) of orchids are the names of more than a hundred doctors, their lives and works perpetuated in the scientific etymology of this family of exotic, beautiful, flamboyant, intriguing and often expensive flowers. Generic names record the lives and works of such as Aristotle (384-322BC) in Aristotelia Loureiro 1790; Cadet de Gassicourt (1769-1821) in Cadetia Gaudichaud 1826; Sir Joseph Dalton Hooker (1817-1911) in Sirhookera O. Kuntze 1891; and Dr Theodore Daniel Vrydag Zynen (fl. 1820-1850) in Vrydagzynea Blume 1858. One of the principal horticultural genera of orchids, Brassavola, records the life and work of the Ferrara and Padua physician and botanist, Antonio Musa Brassavola (1500-1555).

    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.

    The evaluation of permeability in biopharmaceutics classification system of Chinese materia medica (CMMBCS) requires multicomponent as a whole in order to conduct research, even in the study of a specific component, should also be put in the multicomponent environment. Based on this principle, the high content components in Gegen Qinlian decoction were used as multicomponent environmental impact factors in the experiment, and the relevant parameters of intestinal permeability about puerarin were measured with using in situ single-pass intestinal perfusion model, to investigate and evaluate the intestinal permeability of puerarin with other high content components. The experimental results showed that different proportions of baicalin, glycyrrhizic acid and berberine had certain influence on intestinal permeability of puerarin, and glycyrrhizic acid could significantly inhibit the intestinal absorption of puerarin, moreover, high concentration of berberine could promote the absorption of puerarin. The research results indicated that the important research ideas of permeability evaluation in biopharmaceutics classification system of Chinese materia medica with fully considering the effects of other ingredients in multicomponent environment.

    The study is a paticular embodiment of Chinese patent medicine based on biopharmaceutics classification system of Chinese materia medica (CMMBCS) , focusing on assessment of synchronization issues of dissolution that may affect the timing of the multicomponent absorption. The accumulative dissolution percentages of nine components in Gengen Qinlian tablets in different dissolution solvents and times were determined by HPLC. The dissolution curve was drew and its similarity was evaluated by similarity factors (f2) and cluster method. Results in this experiment showed that the components that peak 7 and peak 8 (baicalin) represented had poor similarity with the reference peak 2 (puerarin). Their similarity factors were both 43 in water dissolution media and 31 and 45 in pH 7.4 dissolution media, respectively. Components that peaks represented had better similarity with the reference peak 2 (puerarin) in other medium. It illustrated that components that peak 3,4,5,6 (berberine) represented had fully synchronous dissolution characteristics with the reference peak 2 (puerarin), components peak 1 and 9 represented had nearly fully synchronous dissolution characteristics with the reference peak 2 (puerarin), while components that peak 7 and 8 (baicalin) represented had no synchronous dissolution characteristics with the reference peak 2 (puerarin).

    The cold/hot property of Chinese materia medica (CMM) and the application of its corresponding knowledge in the diagnosis, differentiation and treatment of diseases have been considered to be the extremely important part of traditional Chinese medicine (TCM). As highly abstracted TCM theory, the cold/hot property of CMMs is still not fully understood and remains to be elucidated by systems biology approach. The cold and hot properties of CMM are mainly defined by the response of the body to a given CMM. Metabolomics is a promising systems biology method to profile entire endogenous metabolites and monitor their fluctuations related to an exogenous stimulus. Thus, a metabolomics approach was applied to characterize the cold and hot properties of CMMs. Mice were intragastrically administered three selected cold property CMMs (i.e., Rheum palmatum L., radix et rhizoma; Coptis chinensis Franch, rhizome and Scutellaria baicalensis Georgi, radix) and three hot property CMMs (i.e., Cinnamomum cassia (L.) J. Presl, cortex; Zingiber officinale Roscoe, rhizoma and Evodia rutaecarpa (Juss.) Benth., fructus) once daily for one week. The comprehensive metabolome changes in the plasma of mice after treatment with cold or hot property CMMs were characterized by ultra-high performance liquid chromatography/time of flight mass spectrometry (UHPLC/Q-TOF-MS), and the potential biomarkers related to cold and hot properties of CMM were explored. Metabolites perturbation in plasma occurs after treatment with cold CMMs and hot CMMs in mice, and 15 and 16 differential biomarkers were identified to be associated with the cold and hot properties of CMMs, respectively. Among them, LPC (18:0), LPC (18:1), LPC (20:4) and LPC (20:5) showed decreased trends in the cold property CMM treated groups, but increased in the hot property CMM treated groups. There is a strong connection between the cold/hot property of CMMs and lysophosphatidylcholines metabolism. This study offers new insight

    This study will determine the ways in which the ancient learning (gu xue, ) scholarship of the Seongho School, and its interest in the materia medica (ben cao xue, ) were related during the late Joseon period. The Seongho School centered its studies mainly on classical Chinese texts of the Han (206 BC-AD 220) and pre-Han (?-221 BC) (xian-qin lianghan, ) periods rather than those of the Tang and Song dynasties (618-1279). gu xue scholarship emerged during the Ming dynasty era (1368 -1644) as an alternative to the scholarly trends of the Song dynasty, which were dependent on Zhu Xi's (, 1130-1200) Neo-Confucianism and its interpretation of Han and pre-Han classical Chinese texts. This scholarly trend influenced Korean and Japanese literature, philosophy, and even medicine from the seventeenth through the nineteenth centuries. Focusing on Korean scholarship, we find a great deal of research regarding the influence of gu xue on Korean classical Chinese literature and Confucian philosophy in the late Joseon period; however, no study has examined how this style of scholarship influenced the field of medicine during the same period. This study will investigate how the intellectuals of the Seongho School, who did the most to develop gu xue among Joseon intellectuals, were influenced by this style of scholarship in their study of the materia medica. Jeong Yak-yong (1762-1836), the representative intellectual of the Seongho School, did not focus on complicated metaphysical medical theories, such as the Yin-Yang and Five Elements theory (yin yang wu xing shui, ) or the Five Movements and Six Atmospheres theory (wu yun liu qi shui, ). Instead, his interests lay in the exact diagnoses of diseases and meticulous herbal prescriptions which formed an essential part of the Treatise on Exogenous Febrile Disease (Shang han lun, ) written by Zhang Zhungjing (, 150-219) in the Han dynasty. The Treatise was compatible with the scholarly purpose of gu xue in that they both

    Full Text Available The following study focusses on a precious manuscript from the National Library in Paris, namely n.º 2849 of the Arabic manuscript collection. This is a manuscript of Andalusian origin of the Arabic translation of Materia Medica by Dioscorides, written in Syria at the beginning of the 13th century. Its margins are filled with glosses of synonymic nature, relating to the Greek terms of the plants described by the Greek pharmacologist and physician. These glosses, of Andalusian origin, offer a great terminological richness which is part of a large Arabic — mainly Andalusian — movement of revision and commentary of Materia Medica in Arabic. In the first part a general introduction to the manuscript is provided showing its significant value for a critical edition of the book, the glosses contained and, especially, of the Andalusian botanical glosses, insisting on their synonymic value and their terminological contribution. In a second part, a critical annotated edition of 44 glosses from the first maqāla of the book is proposed.

    Full Text Available DNA barcoding is a novel molecular identification method that aids in identifying traditional Chinese materia medica using traditional identification techniques. However, further study is needed to assess the stability and accuracy of DNA barcoding. Flos Lonicerae Japonicae, a typical medicinal flower, is widely used in China, Korea, and other Southeast Asian countries. However, Flos Lonicerae Japonicae and its closely related species have been misused and traded at varying for a wide range of prices. Therefore, Flos Lonicerae Japonicae must be accurately identified. In this study, the ITS2 and psbA-trnH regions were amplified by polymerase chain reaction (PCR. Sequence assembly was performed using CodonCode Aligner V 3.5.4. The intra- versus inter-specific variations were assessed using six metrics and “barcoding gaps.” Species identification was conducted using BLAST1 and neighbor-joining (NJ trees. Results reveal that ITS2 and psbA-trnH exhibited an average intraspecific divergence of 0.001 and 0, respectively, as well as an average inter-specific divergence of 0.0331 and 0.0161. The identification efficiency of ITS2 and psbA-trnH evaluated using BLAST1 was 100%. Flos Lonicerae Japonicae was formed into one clade through the NJ trees. Therefore, Flos Lonicerae Japonicae can be stably and accurately identified through the ITS2 and psbA-trnH regions, respectively.

    Ischemic stroke and ischemia/reperfusion (I/R) injury induced by thrombolytic therapy are conditions with high mortality and serious long-term physical and cognitive disabilities. They have a major impact on global public health. These disorders are associated with multiple insults to the cerebral microcirculation, including reactive oxygen species (ROS) overproduction, leukocyte adhesion and infiltration, brain blood barrier (BBB) disruption, and capillary hypoperfusion, ultimately resulting in tissue edema, hemorrhage, brain injury and delayed neuron damage. Traditional Chinese medicine (TCM) has been used in China, Korea, Japan and other Asian countries for treatment of a wide range of diseases. In China, the usage of compound TCM preparation to treat cerebrovascular diseases dates back to the Han Dynasty. Even thousands of years earlier, the medical formulary recorded many classical prescriptions for treating cerebral I/R-related diseases. This review summarizes current information and underlying mechanisms regarding the ameliorating effects of compound TCM preparation, Chinese materia medica, and active components on I/R-induced cerebral microcirculatory disturbances, brain injury and neuron damage.

    Yuzhu (Polygonati Odorati Rhizoma), Kangdingyuzhu (Polygonati Prattii Rhizoma), and zhugenqiyuzhu (Disporopsis Fuscopictae Rhizoma) are of the same family, but of different genera. They have all often used in Chinese Materia Medica (CMM) as Polygonati Odorati Rhizoma in China market. Three species of CMM are confused. For better application, we need to identify these plants accurately. This study use pharmacognosy technique and GC-MS analysis, three species of CMM were authenticated. In macroscopic characteristics, the fruit of Polygonati Odorati Rhizoma is blue-black, while the other two are maroon and dark purple orderly. Nodes of Polygonati Odorati Rhizoma are upward and light uplift, about 1 cm spacing, while the other are not. As for microscopic characteristics, the cortex of Polygonati Odorati Rhizoma only occupies about 1/5 of the radius of the transverse section with inconspicuous endodermis, which is much smaller than others. The type of vascular bundles of Polygonati Odorati Rhizoma is closed collateral, but the other is amphivasal. Raphides of calcium oxalate are scattered, but Raphides of the other two are like brooms and neat rows. GC-MS analysis of essential oil could provide different characteristics to distinguish three species. Twenty-three compounds were identified from essential oil of Polygonati Odorati Rhizoma and the main components were n-hexadecanoic acid (49.45%), while n-hexadecanoic acid of the other two are 23.92% and 9.45%. The content of n-hexadecanoic is strongly different. This research was aimed to establish a method by pharmacognosy and GC-MS analysis to identify three CMM and for providing scientifical data to ensure accuracy of origin of three species. © 2014 Wiley Periodicals, Inc.

    Herbarium specimens are the basis for the plant classification and indispensable media in teaching, scientific research and resources investigation. They have also played an important role in identifying and producing traditional Chinese medicine. High-quality herbarium specimens shall meet high requirements for integrity, smoothness, color and fabricating efficiency. Therefore, we designed a rapid setting and drying device for herbarium specimens, which could make the herbarium specimens smooth, colorful and not easy to mildew. In this paper, we pointed out the deficiency of traditional methods in making herbarium specimens, and introduced the structure and working principle of the device. Besides, we also discussed the effect of the device in setting and drying herbarium specimens and its application in the fourth national survey of the Chinese material medica resources (CMMR) in Anhui province. As a result, the device provides new ideas for producing herbarium specimens, with a reasonable design, good uniformity, high efficiency, safety and portability, and so is worthy of promotion and application in the national survey of CMMR.

    To observe the effects of qi-supplementing dominated Chinese materia medica (QSDCMM) combined with rehabilitation training on the quality of life (QOL) of ischemic post-stroke fatigue (PSF) patients of qi deficiency syndrome. Ninety ischemic stroke patients of qi deficiency were randomly assigned to 3 groups, 30 in each. Patients in the Chinese medicine treatment group were treated with oral administration of QSDCMM decoction and rehabilitation. Those in the Western medicine treatment group were treated with Chinese medicine placebo, Western medicine, and rehabilitation. Those in the control group were treated with Chinese medicine placebo and rehabilitation. The therapeutic course for all was 4 weeks. All patients were assessed using Stroke Specific Quality of Life Scale (SS-QOL) and Fatigue Severity Scale (FSS) before treatment and 4 weeks after treatment. After treatment the scores of SS-QOL and FSS increased in the 3 groups, especially in the CM treatment group, showing significant difference (P 0.05). QSDCMM combined with rehabilitation training could improve the QOL of ischemic PSF patients of qi deficiency syndrome.

    In accord with the notions of humoralism that prevailed in medieval medicine, therapeutic interventions, including diuretics, were used to restore the disturbed balance among the four humors of the human body: blood, phlegm, yellow bile, and black bile. Most diuretics were derived from plants. The primary textual reference on herbal diuretics was Dioscorides's De Materia Medica, which was written during the first century CE. The authors reviewed the medieval medical texts written in Persian and Arabic and compiled a list of 135 herbal diuretics used by the medieval medical authorities for treating various ailments. Between the 8th and 11th centuries CE, Middle Eastern physicians systematically reviewed extant books on medicine and pharmacotherapy and compiled new and expanded lists of herbal medicines, diuretics in particular. Furthermore, they introduced new chemical methods of extraction, distillation, and compounding in the use of herbal medicines. Several herbal remedies now are considered as potentially safe and affordable alternatives to chemical pharmaceuticals. Thus, research on medieval herbal therapies may prove to be relevant to the practice of current cardiovascular and renal pharmacotherapy. The authors propose that modern research methods can be employed to determine which of these agents actually are effective as diuretics.

    The major objective in root canal treatment is to disinfect the entire root canal system. Cleaning, shaping, and use of antimicrobial medicaments are effective in reducing the bacterial load to some extent, but some bacteria do remain behind and multiply, causing reinfection. Taking into consideration the ineffectiveness, potential side-effects and safety concerns of synthetic drugs, the herbal alternatives for endodontic usage might prove to be advantageous. Over the past decade, interest in drugs derived from medicinal plants has markedly increased. Phytomedicine has been used in dentistry as anti-inflammatory, antibiotic, analgesic, sedative and also as endodontic irrigant. Herbal preparations can be derived from the root, leaves, seeds, stem, and flowers. The PubMed database search revealed that the reference list for natural medicaments featured 1480 articles and in dentistry 173 articles. A forward search was undertaken on the selected articles and author names. This review focuses on various natural drugs and products as well as their therapeutic applications when used as phytomedicine in dentistry.

    Full Text Available An interesting and highly structured medieval complex, Dobrun has been attracting attention of scholars for a long time. Unlike the ruins of medieval fortifications, the remains of wall-painting in the former monastery church received most of the attention. A series of problems have, however remained open. Some of them have escaped observation, and there are hypotheses that ought to be reassessed. The Dobrun complex is not a matter of local or regional significance. It is a surviving testimony to the events and processes that marked the century preceding the final Ottoman occupation of Serbia and Bosnia. After outlining the research work done to date and analyzing the original historical documents and physical remains, this paper brings the author's views of the issue and some reflections aimed at suggesting directions of further research. The Dobrun complex is situated on the fringe of a hospitable landscape in the lower Rzav valley, not far from Višegrad. It is a region of present-day Republika Srpska on the border with Serbia. The medieval fortifications high up on cliffs above either side of the river controlled the entrance to the gorge, a natural border between western Serbia and Podrinje (the Drina river basin. About a kilometer downstream, on a plot of flat land above the right riverbank, surrounded by rocky hillsides and opening onto a gully cut by a mountain stream, sits the monastic complex of Dobrun with the Church of the Annunciation. The discussion of the structural remains of the complex (Fig. 2 proceed from the multipart whole, which consists of fortifications on the rocks above either bank of the Rzav, built in such a way as to take full advantage of the terrain for defence purposes. The steep slopes and inaccessible rocks complete with walls and towers form a fortress considered at the time of building to be virtually unassailable. Fortification elements were laid out on the western edge of the gorge, which was and still is an

    Melatonin is a hormone with indolaminic structure, produced in the pineal gland during darkness, with chronobiological activity that has been known for decades. It is a physiological inducer of sleep and for this indication has been developed as a drug since many years in many international pharmaceutical markets. It has also a relevant antinflammatory and antioxydant capacity that results in beneficial actions on the liver, on cardiovascular diseases, inflammatory processes, in osteoporosis and also in certain tumours. Its neuroprotective action gives founded expectancies of having potential positive effects in several neurodegenerative diseases like parkinson or Alzheimer. It has been recently approved as a drug in the European Medicament Agency (EMEA) and the Spanish Medicament Agency as well. Some of its more relevant pharmacological actions are reviewed.

    As an important part of the market commodity circulation, the standard grade of Chinese traditional medicine commodity is very important to restrict the market order and guarantee the quality of the medicinal material. The State Council issuing the "protection and development of Chinese herbal medicine (2015-2020)" also make clear that the important task of improving the circulation of Chinese herbal medicine industry norms and the commodity specification standard of common traditional Chinese medicinal materials. However, as a large class of Chinese herbal medicines, the standard grade of the radix is more confused in the market circulation, and lack of a more reasonable study model in the development of the standard. Thus, this paper summarizes the research background, present situation and problems, and several key points of the commodity specification and grade standard in radix herbs. Then, the research model is introduced as an example of Pseudostellariae Radix, so as to provide technical support and reference for formulating commodity specifications and grades standard in other radix traditional Chinese medicinal materials.

Murphy, the three typical medieval forms of rhetoric are the art of letter writing, the art of preaching and the art of poetry (Murphy, 1971, p. xv. In this paper we are concerned only with the second of these arts, namely, the rhetoric of preaching. Though the perceptive treatises on the rhetoric of preaching, the so-called artes praedicandi, did not originate before the thirteenth century, pulpit rhetoric was very much alive in the earlier part of the Middle Ages and fine examples of this kind of eloquence can be quoted.

    Modern, biologic root canal therapy should be performed with suitable irrigating solutions and intracanal medicaments. The goal of endodontic treatment is to free the treated tooth from infection and prevent reinfection as thoroughly as possible by means which do not put the organism at risk. In this review of the literature, an evidence-based concept for irrigation and medication of root canal systems is presented. Irrigants and medicaments are discussed with respect to their antimicrobial, tissue-dissolving and endotoxin-decontaminating capacity in relation to their systemic toxicity. Recent findings pertaining to interactions of root canal medicaments and irrigating solutions and their impact on a sound irrigating and medicating concept are discussed.

    Full Text Available In Russia defensive works were not less important than in Western Europe. Russian chronicles are full of reports of the building of towns, of their siege and defence. In Ancient Russian the word town meant not a town in the modern sense, but only a fortified settlement as distinct from an unfortified one. Thus the concept town applied to medieval towns proper and to citadels, feudal castles and even fortified villages. Every population centre with a wall round it was called a town. Moreover, until the 17th century this word was frequently applied to mean the fortifications themselves.

They generally consisted of a balance between the Galenic "six non-natural things"; factors regulating health and its protection: environment, exercise, food, sleep, bowel movements and emotions. After reviewing the sources and defining the different stages of this genre, we have considered three of the most out-standing medieval regimina, the anonymous Regimen sanitatis salernitanum, Arnaldo de Vilanova's Regimen sanitatis ad regem aragonum and Bernardo de Gordon's Tractatus of conservatione vite humane. In them we review references to neurological disease. Though not independently considered, there is a significant presence of neurological diseases in the regimina. Dietetics measures are proposed to preserve memory, nerves, or hearing, as well as for the treatment of migraine, epilepsy, stroke or dizziness. Regimina are quiet representative among medical medieval literature, and they show medieval physicians vision of neurological diseases. Dietetics was considered useful to preserve health, and therapeutics was based on natural remedies. 2010 Sociedad Española de Neurología. Published by Elsevier Espana. All rights reserved.

    Full Text Available Objective: To explore the clinical efficacy and safety of rituximab combined with chemotherapy and single chemotherapy for diffuse large B cell lymphoma (DLBCL. Methods: A total of 97 patients with DLBCL were selected. Patients treated by single chemotherapy were designed as control group, while those by rituximab combined with chemotherapy as observational group. All patients were treated for at least 4 cycles. The short-term and long-term efficacy and related adverse reactions of 2 groups were observed. Results: The rate of complete remission (CR in observational group was significantly higher than in control group (χ2=4.6589, P=0.0309. However, there was no significant difference in objective remission rate (ORR between 2 groups (P=0.3651. The rates of 3-year overall survival (OS, progression-free survival (PFS and disease-free survival (DFS were 80.30% (53/66, 69.70% (46/66 and 59.09% (39/66 in observational group, and 61.29% (19/31, 58.06% (18/31 and 58.06% (18/31 in control group, respectively. The OS in observational group was significantly longer than in control group (P=0.035. However, there was no significant difference in PFS, DFS and rate adverse reactions between 2 groups (P=0.089; P=0.438; χ2=0.1562, P=0.6927. Conclusion: Rituximab combined with chemotherapy can improve the efficacy of DLBCL without increasing the adverse reactions, which can be used as the first-line treatment for DLBCL, thus deserving to be widely applied in clinic.

  14. Medieval monsters, in theory and practice.

    Science.gov (United States)

    2014-01-01

    The past two decades have witnessed a plethora of studies on the medieval monster. These studies have contributed significantly to our understanding of religion, art, literature, and science in the Middle Ages. However, a tendency to treat the medieval monster in purely symbolic and psychological terms ignores the lived experiences of impaired medieval people and their culture's attitudes toward them. With the aid of recent insights provided by disability studies, this article aims to confront "real" medieval monsters--e.g., physically impaired human beings--in both their human and monstrous aspects.

  18. The "schola medica salernitana": the forerunner of the modern university medical schools.

    Science.gov (United States)

    de Divitiis, Enrico; Cappabianca, Paolo; de Divitiis, Oreste

    2004-10-01

    The schola medica salernitana is considered the oldest medical school of modern civilization. Salerno's long medical tradition began during the Greco-Roman period in a Greek colony named Elea, where Parmenides decided to found a medical school. The fame of the school became more and more important during the 10th century, and it was best known in the 11th century. In the middle of 12th century, the school was at its apogee, and Salerno provided a notable contribution to the formulation of a medical curriculum for medieval universities. The most famous work of the Salernitan School was the Regimen Sanitatis Saleritanum, a Latin poem of rational, dietetic, and hygienic precepts, many of them still valid today. The school also produced a physician's reference book, with advice on how to treat a patient, a sort of code of conduct to help the physician to respect the patient and his or her relatives. The first science-based surgery appeared on the scene of the discredited medieval practice in Salerno, thanks to Roger of Salerno and his fellows. He wrote a book on surgery, called Rogerina or Post Mundi Fabricam, in which surgery from head to toe is described, with surprising originality. The important contribution to the School of Salerno made by women as female practitioners is outlined, and among them, Trotula de Ruggiero was the most renowned. The period when the School of Salerno, universally recognized as the forerunner of the modern universities, became a government academy was when Frederick II reigned over the Kingdom of the Two Sicilies, as Emperor of the Holy Roman Empire.

  19. Medieval theories of mental representation.

    Science.gov (United States)

    Kemp, S

    1998-11-01

    Throughout most of the Middle ages, it was generally held that stored mental representations of perceived objects or events preserved the forms or species of such objects. This belief was consistent with a metaphor used by Plato. It was also consistent with the medieval belief that a number of cognitive processes took place in the ventricles of the brain and with the phenomenology of afterimages and imagination itself. In the 14th century, William of Ockham challenged this belief by claiming that mental representations are not stored but instead constructed in the basis of past learned experiences.

  20. Astronomical Beliefs in Medieval Georgia: Innovative Approaches

    Sauter, Jefferson; Orchiston, W.; Stephenson, F.

    2014-01-01

    Written sources from medieval Georgia show, among other things, how astronomical ideas were adapted on the periphery of the Byzantine and Islamic worlds. In this paper, we investigate a number of Georgian beliefs about the heavens from a calendrical work and a celestial prognostication text, but also from less expected sources including the medieval life of a saint and an epic poem. For the most part, these sources were derived from Byzantine or Persian models. We show the extent to which the sources nevertheless conform to a specifically Georgian view of the cosmos. We argue that, in so doing, medieval Georgian authors employed several innovative approaches hitherto unnoticed by modern scholars.

  1. Quasicrystals in Medieval Islamic Architecture

    Science.gov (United States)

    Lu, Peter

    2009-03-01

    The conventional view holds that girih (geometric star-and-polygon) patterns in medieval Islamic architecture were conceived by their designers as a network of zigzagging lines, and drafted directly with a straightedge and a compass. I discuss our recent findings that, by 1200 A. D., a conceptual breakthrough occurred in which girih patterns were reconceived as tessellations of a special set of equilateral polygons (girih tiles) decorated with lines. These girih tiles enabled the creation of increasingly complex periodic girih patterns, and by the 15th century, the tessellation approach was combined with self-similar transformations to construct nearly-perfect quasicrystalline patterns. These patterns have remarkable properties; they do not repeat periodically, and have special symmetry---and were not understood in the West until the 1970s. I will discuss some of the properties of Islamic quasicrystalline tilings, and their relation to the Penrose tiling, perhaps the best known quasicrystal pattern.

  4. Quantification of virtue in late Medieval Europe.

    Science.gov (United States)

    Kemp, Simon

    2018-02-01

    Fourteenth century Europe saw a growing interest in quantification. This interest has been well studied by historians of physical sciences, but medieval scholars were also interested in the quantification of psychological qualities. In general, the quantification issues addressed by medieval scholars were theoretical, even (by our standards) mathematical, rather than those of practical measurement. There was recognition that the seriousness of a sin and the penance laid down for it should be proportionate. A number of late medieval scholars were interested in the quantification of caritas, a Latin word that is translatable as charity or loving benevolence. The scholastic interest linked to the practical issue of how caritas might become habitual through the repeated performance of virtuous acts. Gregory of Rimini's treatment of caritas in his commentary on Peter Lombard's Sentences illustrates how one medieval scholar related the quantification of virtue to the quantification of physical qualities such as temperature and luminescence.

  5. Analysing Medieval Urban Space; a methodology

    Directory of Open Access Journals (Sweden)

    Marlous L. Craane MA

    2007-08-01

    Full Text Available This article has been written in reaction to recent developments in medieval history and archaeology, to study not only the buildings in a town but also the spaces that hold them together. It discusses a more objective and interdisciplinary approach for analysing urban morphology and use of space. It proposes a 'new' methodology by combining town plan analysis and space syntax. This methodology was trialled on the city of Utrecht in the Netherlands. By comparing the results of this 'new' methodology with the results of previous, more conventional, research, this article shows that space syntax can be applied successfully to medieval urban contexts. It does this by demonstrating a strong correlation between medieval economic spaces and the most integrated spaces, just as is found in the study of modern urban environments. It thus provides a strong basis for the use of this technique in future research of medieval urban environments.

  6. Pharmacological properties of citrus and their ancient and medieval uses in the Mediterranean region.

    Science.gov (United States)

    Arias, Beatriz Alvarez; Ramón-Laca, Luis

    2005-02-10

    This paper reviews the pharmacological properties of Mediterranean-grown citrus species (Citrus L., Rutaceae), including citron (Citrus medica L.), lime (Citrus xauantiifolia [Christm.] Swingle), lemon (Citrus xlimon [L.] Osbeck), bitter orange (Citrus xaurantium L.) and pomelo (Citrus maxima [Burm.] Merr.), as referred to in ancient, medieval and 16th century sources. The virtues of the species reported in these texts were compared to those known to modern science. A much broader spectrum of pharmacological properties was recorded by these early writers than one might expect. The use of the citron and lemon as antidotes for 'poison and venom' is recorded in the very earliest material. According to modern scientific literature the citron and the bitter orange may possess anti-cancer activity, lime may have an immunomodulatory effect in humans, and the pomelo may be useful for treating circulatory problems. Lemons might even ease hangover symptoms. Research is required to confirm these properties.

  7. Basic philosophical texts in Medieval Serbia

    Directory of Open Access Journals (Sweden)

    Milosavljević Boris

    2008-01-01

    Full Text Available Medieval Serbian philosophy took shape mostly through the process of translating Byzantine texts and revising the Slavic translations. Apart from the Aristotelian terminological tradition, introduced via the translation of Damascene’s Dialectic, there also was, under the influence of the Corpus Areopagiticum and ascetic literature, notably of John Climacus’ Ladder, another strain of thought originating from Christian Platonism. Damascene’s philosophical chapters, or Dialectic, translated into medieval Serbian in the third quarter of the fourteenth century, not only shows the high standards of translation technique developed in Serbian monastic scriptoria, but testifies to a highly educated readership interested in such a complex theologico-philosophical text with its nuanced terminology. A new theological debate about the impossibility of knowing God led to Gregory Palamas’ complex text, The Exposition of the Orthodox Faith. Philosophical texts were frequently copied and much worked on in medieval Serbia, but it is difficult to infer about the actual scope of their influence on the formation and articulation of the worldview of medieval society. As a result of their demanding theoretical complexity, the study of philosophy was restricted to quite narrow monastic, court and urban circles. However, the strongest aspect of the influence of Byzantine thought on medieval society was the liturgy as the central social event of the community. It was through the liturgy that the wording of the translated texts influenced the life of medieval Serbian society.

    Directory of Open Access Journals (Sweden)

    María Teresa Muñoz

    2013-10-01

    Full Text Available ResumenLa acumulación material es uno de los signos más identificables de la pobreza. El pobre vive apegado a la tierra, esa es su única posesión y a partir de ella construirá sus refugios, sus habitaciones, sus utensilios. Las construcciones de arcilla, de barro, moldeadas con gran abundancia de materia  se encuentran en los poblados primitivos, pero cualquier situación marcada por la extrema pobreza lo estará también por las acumulaciones de material. Resulta inimaginable una situación de pobreza que no implique la acumulación de materia y esto es particularmente evidente en las sociedades desarrolladas, donde un mendigo es reconocible por su montaña de ropas, calzado o enseres de todo tipo.Resulta, sin embargo, significativo que en los discursos de los ideólogos de la modernidad, la identificación de ésta con el advenimiento de una sociedad sin clases venga acompañada de una apelación a la pobreza, una nueva pobreza fría y sobria, propia de una habitación humana abierta y transparente, casi desnuda, e igualitaria para todos los hombres sin distinción de clases sociales. Así, la pobreza moderna estaría ligada al material, a los nuevos materiales, pero no es una condición impuesta, sino elegida, o al menos aceptada como inevitable por el nuevo hombre.La convivencia entre una pobreza de la acumulación material y una pobreza de ascetismo y renuncia es un hecho tanto en los discursos como en las obras de las vanguardias del siglo XX. La acumulación de materia informe y trabajada manualmente tiene lugar al mismo tiempo que la exhibición de la desnudez y la frialdad de los materiales producidos por la industria.  Y en ambos casos, se apela a la pobreza como última referencia para las obras que tratan de ser una expresión fiel de las aspiraciones de su época.Palabras clavemateria, pobreza, material, acumulación, modernidad, sociedadAbstractAccumulation of matter is one of the most recognizable signs of poverty.

    2012-05-01

    Melk Abbey, a marvel of European high baroque architecture, is one of the most frequently visited tourist attractions in Austria, attracting 450 000 visitors each year. The monastery's museum presents selected aspects of Benedictine life in Melk since the monastery's foundation in 1089. After the church, the library is the second-most important room in a Benedictine monastery. Due to the wide scientific interests and contacts of the medieval monks, these libraries also contain manuscripts on mathematics, physics and astronomy. In 2009, the International Year of Astronomy (IYA2009), the annual library exhibition was fully dedicated to astronomical manuscripts and early prints from the past 1000 years. Following earlier research work on astronomical manuscripts in Melk's library, we were invited to organise the exhibition. In addition, we also presented a lecture series and provided more background in an accompanying book. Because of positive feedback from the visitors, the exhibition was extended until March 2011. In the two years of its duration, the exhibition was seen by more than 900 000 visitors. In this article, we describe the background to the scientific project, how the exhibition was organised and lessons learned from this project.

  11. Medievalism: From Ruskin toChesterton

    Directory of Open Access Journals (Sweden)

    Marko Jenko

    2009-12-01

    Full Text Available This article deals with the topic of medievalism as all existing, still evolving, and future forms of reception of the Middle Ages, focusing primarily on the issues of the term itself and the problems that arise with its definition, its occurrence in John Ruskin’s time, various historical forms, and their variations, especially considering some of the implications of its official or academic aspect – namely, medieval studies in general. Consequently, the article shows that medievalism entails a step beyond or beneath the usual opposition between the real and false Middle Ages. In terms of objectivity as an ideal, as the search or quest for the real Middle Ages (and also as a reaction against subjective receptions, colored by presuppositions, preconceptions, and prejudice, medievalism shifts our perspective on the opposition between the objective and subjective, inaugurating a field of study that centers on the objective-subjective, which should not be seen or taken as a synthesis. Furthermore, it pinpoints a change or shift in the status of truth itself: a truth with no guarantee. Primarily making reference to art history, the article emphasizes the importance of medievalist fantasies and proposes a much needed re-reading of Panofsky’s take on the scholastic habitus. Both terms, fantasy and/or habitus, permeate the field of medievalism, opening what is perhaps the most important question: that of (works of art and materiality.

    Islamic scholars of the Middle Ages are often credited with preserving the scientific writings of Antiquity through the Dark Ages of Europe. Saliba argues that the medieval Islamic astronomers did far more—actually correcting and improving on Greek astronomy by creating new mathematical tools to explain the motions of celestial objects. These tools were so useful that Copernicus appears to have borrowed them for use in his heliocentric cosmology. In this new light, the medieval Islamic astronomers played a fundamental role in the scientific revolution that was forged in Europe during the Renaissance.

The various treatments of fatigue can, in their turn, serve as symptoms to differentiate the medieval anthropologies. This article presents four of their figures: the anthropology of danger elaborated by Augustin, Greek and Arabe medical diagnosis which is passed on the XIth century, and the readings of Aristotle's psychology by Albert the Great and Thomas Aquinas in the XIIIth century.

    Fifty-four subjects, aged between 20 and 35 years, divided into two subgroups, respectively 30 healthy subjects (17 males and 13 females) and 24 subjects with "gonalgia sine materia" (13 males and 11 females) underwent isokinetic exercise test in order to compare their dominant limb with the not dominant one as regard as the strength of extensor and flexor muscles of the knee. No statistically significant difference was found in any of the studied parameters in the comparison between the dominant limb and the not dominant one, both within the subgroup of healthy subjects and within the subgroup of subjects with "gonalgia sine materia". Authors conclude that psychological features may play a preeminent role in the genesis, as well as in the maintenance of "gonalgia sine materia", thus confirming previous data available in medical literature.

    Full Text Available The aim of this study was to evaluate the effect of calcium hydroxide (CH, triple antibiotic paste (TAP and double antibiotic paste (DAP on the push-out bond strengths of three different self-adhesive resin cements. Forty-eight single-rooted human maxillary central incisors were selected. The crowns were removed and the root canals were performed. After the irrigation protocols, the post space was prepared. The teeth were then randomly divided into a control group (no intracanal medicament and three medicament groups (n = 12 for each group. After three weeks, the medicaments were removed using 17% ethylenediaminetetraacetic acid, 2.5% sodium hypochlorite and EndoActivator agitation. The teeth were divided into three subgroups according to the fibre-post luting cement: Maxcem Elite, RelyX Unicem and BisCem. The specimens were sectioned and the push-out test was performed. One-way analysis of variance and Tukey's post hoc tests were used for statistical analyses. Regarding the type of cement, BisCem had significantly lower bond strength values than Maxcem and RelyX. There was no significant difference between the bond strength values of Maxcem and RelyX (p > 0.05. The TAP-RelyX group had the highest bond strength value and the DAP-BisCem group had the lowest bond strength value. RelyX and Maxcem had higher bond strength to root canal dentin than BisCem. The bond strength of BisCem, RelyX and Maxcem was not negatively affected by the use of DAP, CH and TAP as intracanal medicaments.

    Full Text Available Aims. This study examined the extent to which intervisit corticosteroid-based antibiotic pastes (CAP medicaments contribute to staining of tooth structure after attempted removal by irrigation techniques. Methods. A total of 140 roots were prepared and the canals were filled with Ledermix paste (demeclocycline, Odontopaste (clindamycin, and Doxypaste (doxycycline. The pastes were removed after 2 or 4 weeks of storage in the dark using EDTA and NaOCl with either a 27-gauge-slotted needle or an EndoActivator (Dentsply. The roots were then exposed to an intense light source for 30 minutes each week and photographed after a further 1, 3, or 6 months. Digital images were standardized and data for changes in luminosity were analysed using repeated measures ANOVA and a post hoc test. Results. Removal of the medicament did not prevent later discolouration. There was no significant difference between the paste removal methods. Ledermix paste caused the greatest darkening compared to the untreated controls, for both application periods and both methods of removal. Doxypaste and Odontopaste caused less darkening than Ledermix. Conclusion. Medicaments that stain teeth may continue to discolour teeth despite best attempts to remove them. This study stresses the importance of material selection and minimising contact of Ledermix within the coronal aspects of teeth.

    Prevalence and distribution of dental caries in medieval Korean society were evaluated. Two thousand and nine hundred teeth samples of 126 individuals collected from 16th to 18th century Korean tombs. Preservation status of sample was good. The prevalence of ante- and postmortem tooth loss was 4.4% and 14.2%, respectively. The total caries prevalence was 3.9%. The tooth surface most frequently affected by dental caries was occlusal (4.5%), followed by approximal (2.1%), buccal (1.5%), and lingual (1.1%) surfaces. The prevalence of dental caries in Joseon Dynasty skeleton collection was lower than have been found in other collections of similar chronology. The low consumption of refined sugar in medieval Korean society might be a possible explanation, though the technical limitations inherent in such comparison studies preclude definitive conclusions. 2010 Elsevier Ltd.

    Full Text Available The subject matter of this paper is the process of gradual disintegration of monetary system of medieval Serbia during the second half of the 14th and the first half of the 15th century. This period is characterized by an appearance of frequent usurpations of the ruling right to mint coinage by local landlords and the attempts of the rulers from Lazarević and Branković families to restore unified monetary system. Common debasements and restorations of silver coinage provoked economic instability and induced frequent turning backwards to the custom of using weighted silver instead of silver coins as commodity monetary standard. The aim of this paper is to explain the reasons for those phenomena. We apply qualitative, historical, empirical analysis where we consider money minting right holders and their decisions to debase and restore the value of silver dinars. We found that gradual disintegration of monetary system of medieval Serbian State continued until the fall of Serbian Despotate as a consequence of political instability following dissolution of medieval Serbian Empire and economic and financial exhaustion of Serbia by Ottoman suzerains.

    In Iran, a large group of patients are elderly people and they intend to have natural remedies as treatment. These remedies are rooted in historical of Persian and humoral medicine with a backbone of more than 1000 years. The current study was conducted to draw together medieval pharmacological information related to geriatric medicine from some of the most often manuscripts of traditional Persian medicine. Moreover, we investigated the efficacy of medicinal plants through a search of the PubMed, Scopus and Google Scholar databases. In the medieval Persian documents, digestible and a small amount of food such as chicken broth, honey, fig and plum at frequent intervals as well as body massage and morning unctioning are highly recommended. In the field of pharmacotherapy, 35 herbs related to 25 families were identified. Plants were classified as tonic, anti-aging, appetizer, memory and mood enhancer, topical analgesic and laxative as well as health improvement agents. Other than historical elucidation, this paper presents medical and pharmacological approaches that medieval Persian practitioners applied to deal with geriatric complications.

    Pape, K; Westin, S

    1998-12-10

    When Trondheim celebrated its millenium in 1997, this also marked a 1000 year-old medical tradition. In medieval times, sick and disabled people made their pilgrimage to the Nidaros cathedral and the grave of Saint Olav (995-1030). Working from the assumption that every organized society develops rituals and rules to deal with disease and death, we have looked for evidence of what kind of healers one would expect there were in medieval Trondheim up to the reformation in 1537. Sources include reports from archaeological excavations, written material of both medieval and more recent origin, buildings and objects, and living traditions. Three kinds of healer traditions can be identified: The popular and "wise" folk healers were based on traditional pre-Christian mythology and belief in natural forces. The charitable clerics emerged with Christianity. The "professional" wound healers evolved from the needs of the military, later to merge with the early barber surgeons. Traces of scientific traditions, the Salerno school and early European university medicine can be found in local texts, but there is no evidence of any university educated doctor practising in Trondheim before the 17th century.

  1. Ancient and medieval Iberia seen through glass: An archaeometric perspective; La Hispania antigua y medieval a través del vidrio: la aportación de la arqueometría

    2017-11-01

    The study of ancient and medieval glasses has identified distinct compositional groups as a result of the chemical characteristics of the raw materials used for its production. Archaeometric analysis can determine the provenance of the glass, and has demonstrated a large-scale production and commercialisation of raw glass throughout the Mediterranean during the ancient and medieval periods. Secondary workshops on the Iberian Peninsula imported raw glass from the Near East for the better part of the first millennium CE, following a similar pattern observed elsewhere in the Mediterranean region. However, there are some indications that point to a local production of glass and that deserve further investigation. In the ninth century, natron glass was replaced in al-Ándalus by plant ash and lead-rich glass that may represent a local production. Little is known about the production or use of glass in the Christian parts of the peninsula during this period. The increasing volume of analytical data on Spanish glass demonstrates the potential of an archaeometric approach to shed light not only on the production and trade of glass on the Iberian Peninsula but also on the ancient and medieval economy more generally. [Spanish] El estudio del vidrio antiguo y medieval ha permitido identificar distintos grupos composicionales que son resultado de las características químicas de las materias primas empleadas en su fabricación.

  6. Medieval European medicine and Asian spices.

    Science.gov (United States)

    Nam, Jong Kuk

    2014-08-01

    This article aimed to explain the reasons why Asian spices including pepper, ginger, and cinnamon were considered as special and valuable drugs with curative powers in the Medieval Europe. Among these spices, pepper was most widely and frequently used as medicine according to medieval medical textbooks. We analyzed three main pharmacology books written during the Middle Ages. One of the main reasons that oriental spices were widely used as medicine was due to the particular medieval medical system fundamentally based on the humoral theory invented by Hippocrates and Galen. This theory was modified by Arab physicians and imported to Europe during the Middle Ages. According to this theory, health is determined by the balance of the following four humors which compose the human body: blood, yellow bile, black bile, and phlegm. Each humor has its own qualities such as cold, hot, wet, and dry. Humoral imbalance was one of the main causes of disease, so it was important to have humoral equilibrium. Asian spices with hot and dry qualities were used to balance the cold and wet European diet. The analysis of several major medical textbooks of the Middle Ages proves that most of the oriental spices with hot and dry qualities were employed to cure diverse diseases, particularly those caused by coldness and humidity. However, it should be noted that the oriental spices were considered to be much more valuable and effective as medicines than the local medicinal ingredients, which were not only easily procured but also were relatively cheap. Europeans mystified oriental spices, with the belief that they have marvelous and mysterious healing powers. Such mystification was related to the terrestrial Paradise. They believed that the oriental spices were grown in Paradise which was located in the Far East and were brought to the Earthly world along the four rivers flowing from the Paradise.

    This book examines the sustained interest in legends of the pagan and peripheral North, tracing and analyzing the use of an ‘out-of-Scandinavia’ legend (Scandinavia as an ancestral homeland) in a wide range of medieval texts from all over Europe, with a focus on the Anglo-Saxon tradition. The pagan...... North was an imaginative region, which attracted a number of conflicting interpretations. To Christian Europe, the pagan North was an abject Other, but it also symbolized a place from which ancestral strength and energy derived.

    2015-05-01

    Full Text Available If the artistic value of the Romanian medieval embroidery is obvious, it is no less real its documentary value. Most embroided portraits are made on liturgical pieces and they are a proof of the relationship of the rulers with the Orthodox Church. The position of the characters is a mute way of communicating the status that the voievod had. The vertical rigid representations, kneeling, the gestures of the palms and elbows, the beneficence objects, the way characters are grouped, the proportion or their placement in the work can be symbolically interpreted depending on the type of the Liturgical item on which the embroidery was done.

    In contrast to other articles in this series on the history of moral philosophy the present essay is not devoted to expounding the views of a single author, or to examining a particular moral theory. Instead it discusses an important dispute between two medieval accounts of the relation between theological and moral propositions. In addition to its historical interest this debate is important both because it connects earlier and later ethical thought--being influenced by Greek moral theories and influencing subsequent European philosophy--and because it concerns issues that remain important to philosophers and to those who claim that their ethical beliefs are dictated by religious convictions.

    We applied the proton-induced X-ray emission (PIXE) analytical technique to twenty-eight medieval silver coins, selected from the Tunisian treasury. The purpose is to study the fineness evolution from the beginning of the 7th to the 15th centuries AD. Each silver coin was cleaned with a diluted acid solution and then exposed to a 3 MeV proton beam from a 1.7 MV tandem accelerator. To allow the simultaneous detection of light and heavy elements, a funny aluminum filter was positioned in front of the Si(Li) detector entrance which is placed at 135{sup o} to the beam direction. The elements Cu, Pb, and Au were observed in the studied coins along with the major component silver. The concentration of Ag, presumably the main constituent of the coins, varies from 55% to 99%. This significant variation in the concentration of the major constituent reveals the economical difficulties encountered by each dynasty. It could be also attributed to differences in the composition of the silver mines used to strike the coins in different locations. That fineness evolution also reflects the poor quality of the control practices during this medieval period. In order to verify the ability of PIXE analytical method to distinguish between apparently similar coins, we applied hierarchical cluster analysis to our results to classify them into different subgroups of similar elemental composition.

  15. Some more earthquakes from medieval Kashmir

    2014-07-01

    Kashmir has the peculiarity of having written history of almost 5,000 years. However, the description of earthquakes in the archival contents is patchy prior to 1500 a.d. Moreover, recent search shows that there exist certain time gaps in the catalogs presently in use especially at medieval level (1128-1586 a.d.). The presence of different ruling elites in association with socioeconomic and political conditions has in many ways confused the historical context of the medieval sources. However, by a meticulous review of the Sanskrit sources (between the twelfth and sixteenth century), it has been possible to identify unspecified but fair number (eight seismic events) of earthquakes that do not exist in published catalogs of Kashmir or whose dates are very difficult to establish. Moreover, historical sources reveal that except for events which occurred during Sultan Skinder's rule (1389-1413) and during the reign of King Zain-ul-Abidin (1420-1470), all the rediscovered seismic events went into oblivion, due mainly to the fact that the sources available dedicated their interests to the military events, which often tended to overshadow/superimpose over and even concealed natural events like earthquakes, resulting in fragmentary accounts and rendering them of little value for macroseismic intensity evaluation necessary for more efficient seismic hazard assessment.

Scattered throughout the work are a number of lucid remarks on the character of Islamic mathematics or of mathematical work in general. The book will hence not only be an excellent textbook for the teaching of the history of mathematics but also for the liberal art aspect of mathematics teaching in general. - Jens Høyrup, Mathematical Reviews ...as a textbook, this work is highly commendable...It is definitely the product of a skillful mathematician who has collected over the years a reasonably large number of interesting problems from medieval Arab...

    Polish periodicals published since the beginning of 19th century contained household knowledge which was of great importance to peasants. In the second half of 19th century the number of articles related to prevention, treatment as well as life hygiene (including nutrition guidance) enlarged significantly. The term "household medicine box# was very often used in periodicals as titles of both: sections dedicated to hygiene or medicine as well as for articles describing medicaments intended to be kept in the boxes. Articles referenced law regulations stated in "law for pharmacists and pharmacies# from 1844. The availability of medical handbooks widened with the end of the century and this fact may have caused the changes in profiles of numerous medical sections in popular periodicals. However the changes did not affect publications related to contents of medical boxes.

    Full Text Available In this paper we present the mathematical and topographic analysis of orientation of the most significant churches (11 of Morava school, the last style in architecture of medieval Serbia whose executors were chief architects. The deviation from equinox East of the main axis of each church and the dates when the Sun rises on the physical horizon, in the extension of the main axis, have been calculated. These were the dates when the church could have been oriented towards the rising Sun. This possibility has been ruled out for four churches. As for the other churches, the matching of the mentioned dates with the patron’s days wasn’t established. The churches in monasteries Ljubostinja and Kalenic are oriented with astronomical precision towards equinox East, an admirable fact considering the tools available to the builders. Rade Borovic, the only chief architect who put his signature on his work, was the chief architect of Ljubostinja.

  2. Medieval iconography of watermelons in Mediterranean Europe

    Paris, Harry S.; Daunay, Marie-Christine; Janick, Jules

    2013-01-01

    Background and Aims The watermelon, Citrullus lanatus (Cucurbitaceae), is an important fruit vegetable in the warmer regions of the world. Watermelons were illustrated in Mediterranean Antiquity, but not as frequently as some other cucurbits. Little is known concerning the watermelons of Mediterranean Europe during medieval times. With the objective of obtaining an improved understanding of watermelon history and diversity in this region, medieval drawings purportedly of watermelons were collected, examined and compared for originality, detail and accuracy. Findings The oldest manuscript found that contains an accurate, informative image of watermelon is the Tractatus de herbis, British Library ms. Egerton 747, which was produced in southern Italy, around the year 1300. A dozen more original illustrations were found, most of them from Italy, produced during the ensuing two centuries that can be positively identified as watermelon. In most herbal-type manuscripts, the foliage is depicted realistically, the plants shown as having long internodes, alternate leaves with pinnatifid leaf laminae, and the fruits are small, round and striped. The manuscript that contains the most detailed and accurate image of watermelon is the Carrara Herbal, British Library ms. Egerton 2020. In the agriculture-based manuscripts, the foliage, if depicted, is not accurate, but variation in the size, shape and coloration of the fruits is evident. Both red-flesh and white-flesh watermelons are illustrated, corresponding to the typical sweet dessert watermelons so common today and the insipid citron watermelons, respectively. The variation in watermelon fruit size, shape and coloration depicted in the illustrations indicates that at least six cultivars of watermelon are represented, three of which probably had red, sweet flesh and three of which appear to have been citrons. Evidently, citron watermelons were more common in Mediterranean Europe in the past than they are today. PMID:23904443

    Full Text Available Novas tecnologias diagnósticas e terapêuticas são cada vez mais utilizadas, melhorando a qualidade assistencial e aumentando a expectativa de vida; entretanto, a atenção à saúde vem se tornando mais cara e complexa. Os eventos adversos relacionados à assistência, especialmente os erros, são cada vez mais conhecidos, discutidos e julgados em tribunais. Os profissionais de saúde, devido à sua formação, não estão preparados para lidar com os erros, pois estes estão associados à vergonha, ao medo e às punições. A abordagem dos erros no sistema de saúde é, geralmente, feita de forma individualista, considerando os erros como atos inseguros cometidos por pessoas desatentas, desmotivadas e com treinamento deficiente. Quando o erro ocorre, a tendência é escondê-lo, perdendo-se oportunidade importante de aprendizado. Existe outro modo de lidar com erros, a visão sistêmica, que na sua aplicação apresenta bons resultados em setores como aviação, anestesia e sistemas de distribuição de medicamentos por dose unitária. Os sistemas possuem graus variados de segurança e devem levar em conta, na sua construção e funcionamento, as limitações humanas. Em relação ao uso dos medicamentos, uma mudança de paradigma é necessária, pois não basta um medicamento ter qualidade garantida, mas o seu processo de utilização também deve ser seguro. Os erros de medicação, que são por definição evitáveis, são atualmente um sério problema de saúde pública, levando a perdas de vidas e desperdício importante de recursos financeiros. A abordagem sistêmica dos erros de medicação poderá revelar as falhas do processo, sendo possível implementar melhorias, diminuindo, assim, a ocorrência desses eventos.

    In Medieval Europe, soldiers wore steel plate armour for protection during warfare. Armour design reflected a trade-off between protection and mobility it offered the wearer. By the fifteenth century, a typical suit of field armour weighed between 30 and 50 kg and was distributed over the entire body. How much wearing armour affected Medieval soldiers' locomotor energetics and biomechanics is unknown. We investigated the mechanics and the energetic cost of locomotion in armour, and determined...

  13. Why We Need a Medieval Narratology: A Manifesto

    Directory of Open Access Journals (Sweden)

    Eva von Contzen

    2014-12-01

    Full Text Available In the wake of the growing interest in diachronic approaches and the historicizing of narratology, a medieval narratology is called for which systematically scrutinizes medieval forms and functions of narration. In the first part of the article, the problems of applying classical narratological theories to medieval literature are sketched, as well as the reasons for the relative invisibility of the narratological studies already conducted by medievalists. In the second part, the main parameters of a medieval narratology are outlined by means of selected sample analyses across a range of genres. A medieval narratology, it is argued, requires necessary shifts and modifications of existing theories, but also an open dialogue between the disciplines. Both narratologists and medievalists can profit from such an endeavor, which does not reject classical and post-classical theories. Rather, it is based on an informed understanding of the historical grounding of narrative forms and their place in the history of literature. The essay rounds off with a proposal of “Ten Theses for a Medieval Narratology”.

    To assess the knowledge, attitude, and practice of pediatricians regarding pediatric liquid medicaments (PLMs) and its effect on dental health. A convenience sample of 103 pediatricians was asked to answer a questionnaire. A total number of 87 pediatricians completed the questionnaires. They considered age and body weight of the child (58%), cost of the medicine (40%), and pharmaceutical company (37%) to be relevant while prescribing. Eighty-eight percent of pediatricians knew that the PLM was sweet in nature. Sixty-seven percent of pediatricians stated that pH of PLM is responsible for deleterious effect on teeth. Seventy-two percent of pediatricians were aware of hidden sugars present in PLM. Only 48% of pediatricians were aware of availability of sugar-free medicine. Seventy percent of pediatricians were of the opinion that sugar-free medicine is not as sweet as sugar-containing medicines and is more expensive (65%). Knowledge, attitude, and practice of pediatricians regarding PLMs and its effect on dental health were not satisfactory.

    In this study, the effect of aqueous extraction conditions (temperature of 70-90°C, time of 60-180min, and liquid/solid ratio (LSR) of 20-40v/w) on the yield and degree of esterification (DE) of Citrus medica peel pectin was studied using a Box-Behnken design. The highest production yield of pectin (21.85±0.35%) was obtained at temperature of 90°C, extraction time of 180min and LSR of 40v/w as optimum extraction conditions which was close to the predicted value (24.13%). In these extraction conditions, the DE and the emulsifying activity were 77.2 and 46.5%, respectively. Also, the emulsions were 90.30 and 90% stable at 4°C, and 83.87 and 83.50% at 25°C after 1 and 30days, respectively. The determination of flow behavior showed that the pectin solutions had a Newtonian behavior at low concentrations (0.1, 0.5 and 1.0%w/v), while in higher concentration (2.0%w/v), the pseudoplastic flow behavior became dominant.

    2007-08-01

    Successful treatment of apical periodontitis is dependent on the elimination of the infective microflora from the necrotic root canal system. Antimicrobial irrigating solutions and other locally used disinfecting agents and medicaments have a key role in the eradication of the microbes. While most if not all presently used disinfecting agents rapidly kill even the resistant microbes when tested in vitro in a test tube, the effectiveness of the same agents is clearly weaker in the in vivo conditions. Recent studies have given valuable information about the interaction of endodontic disinfecting agents with dentin and other compounds present in the necrotic root canal. As a result of such interactions the antimicrobial effectiveness of several of our key disinfectants may be weakened, or even eliminated under certain circumstances. Different disinfectants show different sensitivity to the action by the various potential inactivators, such as dentin, serum proteins, hydroxyapatite, collagen derived from different sources, and microbial biomass. This review is a summary of our present knowledge of the mostly negative interactions between endodontic disinfecting agents and the various compounds present in the root canal environment.

    Yassen, Ghaeth H.

    Endodontic regeneration treatment of necrotic immature teeth has gained popularity in recent years. The approach suggests a biological alternative to induce a continuous root development. In this project, three in vitro experiments were conducted to investigate the effect of three medicaments used in endodontic regeneration on mechanical properties and chemical structure of radicular dentin. In the first experiment, we investigated longitudinally the effect of medicaments on the indentation properties of the root canal surface of immature teeth using a novel BioDent reference point indenter. A significant difference in the majority of indentation parameters between all groups was found after one-week and one-month application of medicaments (p double antibiotic paste (DAP) > control > calcium hydroxide [Ca(OH)2]. The four-week exposure of dentin to TAP and DAP caused 43% and 31% increase in total indentation distance outcome, respectively. In the second experiment, we investigated longitudinally the effect of medicaments on the chemical structure of immature radicular dentin by measuring the phosphate/amide I ratios of dentin using Attenuated Total Reflection Fourier Transform Infrared Spectroscopy. Phosphate/amide I ratios were significantly different between the four groups after one week, two weeks and four week application of medicaments (p untreated dentin > DAP-treated dentin > TAP-treated dentin. In the third experiment, we investigated longitudinally the effect of medicaments on root fracture resistance and microhardness of radicular dentin. For the microhardness, the two-way interaction between group and time was significant (pmedicaments caused significant decrease in fracture resistance ranging between 19%-30% after three month application compared to one week application. The three medicaments used in endodontic regeneration caused significant change in the chemical integrity of the superficial radicular dentin and significantly affected the indentation

    The aim of the study was to investigate the inactivation by dentine of the antibacterial activity of various commonly used local root canal medicaments. The medicaments tested were saturated calcium hydroxide solution, 1% sodium hypochlorite, 0.5% and 0.05% chlorhexidine acetate, and 2/4% and 0.2/0.4% iodine potassium iodide. Dentine was sterilized by autoclaving and crushed into powder with a particle size of 0.2-20 microns. Aliquots of dentine suspension were incubated with the medicaments in sealed test tubes at 37 degrees C for 24 h or 1 h before adding the bacteria. In some experiments bacteria were added simultaneously with dentine powder and the medicament. Enterococcus faecalis A197A was used as a test organism. Samples for bacterial culturing were taken from the suspensions at 5 min, 1 h and 24 h after adding the bacteria. Dentine powder had an inhibitory effect on all medicaments tested. The effect was dependent on the concentration of the medicament as well as on the length of the time the medicament was preincubated with dentine powder before adding the bacteria. The effect of calcium hydroxide on E. faecalis was totally abolished by the presence of dentine powder. Similarly, 0.2/0.4% iodine potassium iodide lost its effect after preincubation for 1 h with dentine before adding the bacteria. The effect of 0.05% chlorhexidine and 1% sodium hypochlorite on E. faecalis was reduced but not totally eliminated by the presence of dentine. No inhibition could be measured when full strength solutions of chlorhexidine and iodine potassium iodide were used in killing E. faecalis. The dentine powder model appears to be an efficient tool for the study of interactions between local endodontic medicaments, dentine, and microbes.

  1. Medieval herbal iconography and lexicography of Cucumis (cucumber and melon, Cucurbitaceae) in the Occident, 1300-1458.

    2011-09-01

    The genus Cucumis contains two species of important vegetable crops, C. sativus, cucumber, and C. melo, melon. Melon has iconographical and textual records from lands of the Mediterranean Basin dating back to antiquity, but cucumber does not. The goal of this study was to obtain an improved understanding of the history of these crops in the Occident. Medieval images purportedly of Cucumis were examined, their specific identity was determined and they were compared for originality, accuracy and the lexicography of their captions. The manuscripts having accurate, informative images are derived from Italy and France and were produced between 1300 and 1458. All have an illustration of cucumber but not all contain an image of melon. The cucumber fruits are green, unevenly cylindrical with an approx. 2:1 length-to-width ratio. Most of the images show the cucumbers marked by sparsely distributed, large dark dots, but images from northern France show them as having densely distributed, small black dots. The different size, colour and distribution reflect the different surface wartiness and spininess of modern American and French pickling cucumbers. The melon fruits are green, oval to serpentine, closely resembling the chate and snake vegetable melons, but not sweet melons. In nearly all manuscripts of Italian provenance, the cucumber image is labelled with the Latin caption citruli, or similar, plural diminuitive of citrus (citron, Citrus medica). However, in manuscripts of French provenance, the cucumber image is labelled cucumeres, which is derived from the classical Latin epithet cucumis for snake melon. The absence of melon in some manuscripts and the expropriation of the Latin cucumis/cucumer indicate replacement of vegetable melons by cucumbers during the medieval period in Europe. One image, from British Library ms. Sloane 4016, has a caption that allows tracing of the word 'gherkin' back to languages of the geographical nativity of C. sativus, the Indian

  3. Light - Shadow Interactions in Italian Medieval Churches

    Science.gov (United States)

    Incerti, Manuela

    In the relationship between architecture and the sky, it is possible to identify three different design issues. The first regards the alignment of buildings with visible points on the horizon that coincide with the rising or setting of a celestial body (sun, planets, stars, or moon) on particular dates during the astronomical year (or liturgical year for sacred buildings). The second is the relationship between planimetric design and the design of the elevations. We are all familiar today with several "light effects", which sometimes have almost hierophanic characteristics that, on certain days of the year, were used to engross, captivate, and amaze the spectator. Contrary to the first two issues, the third comes after the design and building stages and concerns the question of decorative elements. It is reasonable to believe that many years after the works were terminated, certain wall finishings were chosen over others, such as painted frescoes or statues. Whoever did this was fully aware, thanks to direct observation, that such decoration would be struck by a single ray of light on a specific day. This chapter examines light-shadow interactions in some Italian medieval churches.

    Three medieval illuminated manuscripts (codd. Lat. b. 1; Lat. b. 2; Lat. e. 4), housed at the University of Notre Dame's Hesburgh Library, vary in style, pigments, scribes, and regions, despite all three being Psalters used in the Late Middle Ages. XRF and Raman spectroscopy, which provided the elemental and molecular composition of the pigments, respectively, were used to analyze the pigments' compositions in an attempt to narrow further the manuscripts' possible origins. This experimental investigation emphasizes the importance of understanding the history of the manuscript through their pigments. Codd. Lat. b. 1 and Lat. b. 2 are Latinate German Psalters from the fifteenth century likely used in Katharinenkloster in Nuremberg. While there are visible differences in style within each Psalter, the variations in some of the pigment compositions, such as the inconstant presence of zinc, suggest different admixtures. Cod. Lat. e. 4 is a Latinate English Psalter from the fourteenth century, and it was written by two scribes and illuminated by two distinct painters. It is currently being tested to determine whether there are any correlations between the scribes and painters. These physical analyses will clarify the origins and provenances of the manuscripts.

    Pajić, Sanja; Jurišić, Vladimir

    2015-01-01

    The topic of this study are representations of lancet or phlebotome in frescoes and icons of Serbian medieval art. The very presence of this medical instrument in Serbian medieval art indicates its usage in Serbian medical practices of the time. Phlebotomy is one of the oldest forms of therapy, widely spread in medieval times. It is also mentioned in Serbian medical texts, such as Chilandar Medical CodexNo. 517 and Hodoch code, i.e. translations from Latin texts originating from Salerno-Montpellier school. Lancet or phlebotome is identified based on archaeological finds from the Roman period, while finds from the Middle Ages and especially from Byzantium have been scarce. Analyses of preserved frescoes and icons has shown that, in comparison to other medical instruments, lancet is indeed predominant in Serbian medieval art, and that it makes for over 80% of all the representations, while other instruments have been depicted to a far lesser degree. Examination of written records and art points to the conclusion that Serbian medieval medicine, both in theory and in practice, belonged entirely to European traditions of the period.

    Music and dance, the esoteric performing arts, were markers of culture in medieval India. A number of these differing forms developed into well-recognized and reputed arts over time. The practitioners were, accordingly, regarded as agents of refinement and culture. At the same time, music and dance were also among the most popular forms of entertainment and physical pleasure. This aspect remained crucial in classifying musicians, singers and dancers as entertainers, alongside prostitutes. While the labelling together might have reduced the status of performers at times, the labelling hardly remained fixed. Certain practitioners, even if involved in practices otherwise considered immoral, could remain within the elite circle, while for others the ‘evil’ characteristics got emphasized. There were, within the class of women who prostituted themselves, courtesans trained in the skills of music and dancing and educated in the fine arts, who were treated more as embodiments of culture. These categories—artists, skilled entertainers, courtesans—were quite fluid, with the boundaries seemingly fused together. Still, there were certainly some distinctions among the categories and those did not totally disappear, affording sanctity and purity to certain kinds of performers and allowing them to claim distinctiveness. Notably, the class of courtesans clearly stood apart from the common prostitutes. The attempt in this article is to look at different categories of women performers and prostitutes, their apparent coalescing boundaries and specialities as a separate group, their societal position, their shifting roles and the changes that affected their status. In this, it is worthwhile to consider the state’s attitude towards them, besides societal views that remained quite diverse.

    The current investigations on the treatment of worn-out medicaments in Mexico, reveal that most of these treatments are carried out with the purpose to reduce the packing and diminish the toxic level that presents each one of those medicaments. That it reach to reuse of them is their packing material and/or their cover. Once treated, the worn-out medicaments move to a sanitary filler. With relationship to the investigation works that have been carried out for the manganese removal in solution, they show a great number of materials that they are used for this end, as well as the parameters that influence in the process, such as the concentration of the element, the solution type in that is content and the pH. However, it is not mentioned in none of them the reuse of the worn-out medicaments (Talcid and Melox), as adsorbent materials for the removal of metals from the water. To carry out the present investigation they were selected therefore, to the one Talcid and the Melox because its present adsorbent properties, with the purpose to remove the manganese like water pollutant. Once that the worn-out medicaments were obtained, they put on in contact with different organic solvents, to obtain the active principle, due to the pharmaceutical presentation of the two medicaments that was obtained was in suspension. The active principles of the two medicaments were characterized by means of high vacuum scanning electron microscopy (SEM), elementary microanalysis (EDS) and X-ray diffraction (XRD). The experimental part consisted in putting in contact manganese solutions with the active principles of the worn-out medicaments, varying the time of contact and the concentration. The manganese quantification in the liquid phase carried out by means of atomic absorption spectroscopy (AAS). It was found that the kinetic model that better describes the sorption process of manganese in both worn-out medicaments (Talcid and Melox) it is that of pseudo second order. Those results of

  14. Role of Light - Shadow Hierophanies in Early Medieval Art

    Science.gov (United States)

    Ataoguz, Kirsten

    In the early Middle Ages, solar observance shaped the art and architecture of Christian churches in primarily three ways. First, medieval writers from across the Mediterranean often related dramatic lighting effects to alignment with the rising sun on astronomically and liturgically significant days. Second, in still-surviving pictorial compositions, light coming in through strategically placed windows aligned with the east-west axis stands in for Christ in a variety of recognizable compositions. Third, archaeoastronomers have hypothesized that select medieval pictorial programs were coordinated with fenestration to spotlight-specific scenes and figures on specific days and at specific hours.

    Lesions consistent with skeletal tuberculosis were found in 13 individuals from an early medieval skeletal sample from Courroux (Switzerland). One case of Pott's disease as well as lytic lesions in vertebrae and joints, rib lesions and endocranial new bone formation were identified. Three individuals with lesions and one without were tested for the presence of Myobacterium tuberculosis complex (MTBC) ancient DNA (aDNA), and in two cases, evidence for MTBC aDNA was detected. Our results suggest the presence of tuberculosis in the analysed material, which is in accordance with other osteological and biomolecular research that reported a high prevalence of tuberculosis in medieval skeletons.

    Full Text Available One of the major issues in building archaeology is finding the age of elements and structures discovered. Mortars represent a class of material basically constituted by a mixture of different phases (i.e. binder, aggregates, water and are widely used for constructive uses and artworks. Current scientific literature regarding the possibility of accurate radiocarbon dating for mortars reports different and still contradictory results. In this study, a new protocol for radiocarbon dating of mortar developed at the Centre for Isotopic Research on Cultural and Environmental heritage (CIRCE is used to perform 14C measurements on archaeological mortars coming from three medieval architectures of northern Spain (two churches and the walls of a castle. Results observed will be discussed and compared with independent age estimations (i.e. radiocarbon dating performed on organic materials found in the same study site, archaeological analyses in order to frame experimental observations in the actual site knowledge by means of a multidisciplinary approach.Una de las principales problemáticas a las que se enfrenta la arqueología de la arquitectura es datar los elementos y las estructuras.

  18. Saving the Phenomena in Medieval Astronomy

    Seeskin, K.

    2011-06-01

    Aristotle's theory of motion is based on two principles: (1) all motion to either from the midpoint of the Earth, toward it, or around it, and (2) circular motion must proceed around an immovable point. On this view, the heavenly bodies are individual points of light carried around by a series of concentric spheres rotating at a constant pace around the midpoint of the Earth. But even in Aristotle's day, it was known that this theory had a great deal of difficulty accounting for planetary motion. Ptolemy's alternative was to introduce epicycles and eccentric orbits, thus denying Aristotle's view of natural motion. There was no doubt that Ptolemy's predictions were far better than Aristotle's. But for the medievals, Aristotle's theory made better intuitive sense. Moreover, Ptolemy's theory raised the question of how one sphere could pass through another. What to do? The solution of Moses Maimonides (1138-1204) was to say that it is not the job of the astronomer to tell us how things actually are but merely to propose a series of hypotheses that allow us to explain the relevant data. This view had obvious theological implications. If astronomy could explain planetary motion in an acceptable way, there was reason to believe that the order or structure of the heavens is what it is by necessity. This suggests that God did not exercise any degree of choice in making it that way. But if astronomy cannot explain planetary motion, the most reasonable explanation is that we are dealing with contingent phenomena rather than necessary ones. If there is contingency, there is reason to think God did exercise a degree of choice in making the heavens the way they are. A God who exercises choice is much closer to the God of Scripture. Although Galileo changed all of this, and paved the way for a vastly different view of astronomy, the answer to one set of questions raises a whole different set. In short, the heavenly motion still poses ultimate questions about God, existence, and

    Full Text Available "nBackground and Aim: Researches have shown that bacteria play the main role in development of pulpal and periapical diseases. Chemo-mechanical cleaning of infected root-canal system can not remove all of the microorganisms. Thus interappointment medicaments are necessary to aid this goal. Calcium hydroxide is one of the most useful medicaments in root canal therapy, but this medicament can not eliminated all of the bacteria in root canal system. Carvacrol is an edible plant extract that has antimicrobial and anti-inflammatory effects. If this extract is effective against endodontic bacteria, it can be used as an root canal medicament. "nMaterials and Methods: In this experimental study, Initially, MIC and MBC of carvacrol detected with Macro broth dilution method and determined as 0.3% and 0.6%, respectively. After that, 30 single root and single canal extracted human teeth were used in this study. The number of specimens determined in a pilot study on 4 extracted teeth. After preparation to apical size # 30 with hand and rotary instruments, teeth were randomly divided into two experimental and two control groups. After culturing Enterococcus faecalis in prepared canals, we used emulsion of 0.6% carvacrol and calcium hydroxide in two A and B experimental groups for 7 days as the intracanal medicament.

  6. Social representations of memory and gender in later medieval England.

    Kane, Bronach

    2012-12-01

    Social representations in later medieval culture have attracted little attention amongst psychologists, pre-dating the development of the so-called 'public sphere' in the eighteenth century. In addition, the association of pre-modern societies with 'traditional' modes of communication in social psychology places implicit limits on areas that may be studied through the lens of social representation theory. This article analyses the way in which knowledge circulated in late medieval society, noting initially the plural nature of representations of events and marginal groups, and the myriad channels through which beliefs were consolidated. In later medieval England perceptions of the past depended on collective and group memory, with customary rights and local histories forged through 'common knowledge', hearsay and the opinions of 'trustworthy men' of the village. The final section of this commentary provides an analysis of testimony from the late medieval church courts, in which witnesses articulated gender ideologies that reflected perceptions drawn from everyday life. Social representations of women were thus deployed in ecclesiastical suits, on the one hand supporting evidence of female witnesses and on the other justifying misogynistic stereotypes of women's behaviour.

    Stefania Vai

    Full Text Available In the period between 400 to 800 AD, also known as the period of the Barbarian invasions, intense migration is documented in the historical record of Europe. However, little is known about the demographic impact of these historical movements, potentially ranging from negligible to substantial. As a pilot study in a broader project on Medieval Europe, we sampled 102 specimens from 5 burial sites in Northwestern Italy, archaeologically classified as belonging to Lombards or Longobards, a Germanic people ruling over a vast section of the Italian peninsula from 568 to 774. We successfully amplified and typed the mitochondrial hypervariable region I (HVR-I of 28 individuals. Comparisons of genetic diversity with other ancient populations and haplotype networks did not suggest that these samples are heterogeneous, and hence allowed us to jointly compare them with three isolated contemporary populations, and with a modern sample of a large city, representing a control for the effects of recent immigration. We then generated by serial coalescent simulations 16 millions of genealogies, contrasting a model of genealogical continuity with one in which the contemporary samples are genealogically independent from the medieval sample. Analyses by Approximate Bayesian Computation showed that the latter model fits the data in most cases, with one exception, Trino Vercellese, in which the evidence was compatible with persistence up to the present time of genetic features observed among this early medieval population. We conclude that it is possible, in general, to detect evidence of genealogical ties between medieval and specific modern populations. However, only seldom did mitochondrial DNA data allow us to reject with confidence either model tested, which indicates that broader analyses, based on larger assemblages of samples and genetic markers, are needed to understand in detail the effects of medieval migration.

    Full Text Available Patriarch Ephrem, monk and hermit, writer and saint, Bulgarian-born but twice the leader of the Serbian Church (1375-78 and 1389-92, is an outstanding figure of the late medieval Balkans. His "life and works" are discussed here in the light of hagiological texts and the information provided by various types of sources with the view to drawing some historically relevant conclusions. The main source of information about Ephrem's life and activity are the eulogies, Life and service composed by bishop Mark, his disciple and loyal follower for twenty-three years. Making use of hagiographical topica combined with plentiful data of undoubted documentary value, he relates the story of Ephrem's life through all of its major stages: from his birth and youth to his withdrawal from the world and taking of a monk's habit. Of formative influence were his years on the Holy Mount Athos, where he experienced different styles of monastic life, coenobitic, as well as solitary, which he practiced in the well-known hermitages in the heights of Athos. The further course of Ephrem's life was decided by the turbulent developments in the Balkans brought about by the Ottoman conquests. In that sense, his biography, full of forced and voluntary resettlements, is a true expression of the spirit of the times. Forced to flee Mount Athos, Ephrem made a short stay in Bulgaria and then, about 1347, came to Serbia, where he spent the rest of his life. An eminent representative of the monastic elite and under the aegis of the Serbian patriarch, he spent ten years in a hesychastria of the Monastery of Decani. For reasons of security, he then moved to a cave hermitage founded specially for him in the vicinity of the Patriarchate of Pec. It was in that cell, where he lived for twenty years powerfully influencing the monastic environment, that his literary work profoundly marked by hesychast thought and eschatology, was created. Ephrem twice accepted the office of patriarch in the

    Acta Informatica Medica is official journal of the Academy for Medical Sciences of Bosnia and Herzegovina (from 2014 Acta Inform Med is published bimonthly). To evaluate journal "Acta Informatica Medica" in 2015 and compare findings to previous years. The study has retrospective and descriptive character, and included the period 2008-2015 (included 36 issues of journal). A total of 83 (average 13,8 articles per journal) articles were published in Acta Informatica Medica during 2015. Analyzing the type of articles, original articles are present in majority during 2015 (68,6%) (by analyzing last eight years, 310 (67,3%) were original). During 2015, 27,7% of articles were related to the applied of Health informatics in field of clinical medicine, 63,8% preclinical medicine and 8,5% to public health. Collaboration rate in 2015 was 0,84. Most often the time required for decision on acceptance of article in 2015 is between 50 and 60 days. Articles came from 16 countries. According to scimagojr.com for 2014, Acta Informatica Medica has SCImago Journal Rank 0,166, while Cites / Doc. (2 years) parameter (widely used as impact index) is 0,70. According to GoogleScholar, h5 index is 11 and h5 median is 19. We analyzed the Acta Informatica Medica by "Publish or Perish" software - H index was 14, g index was 19 and e-index was 10.39. Year after year the highest number of original articles are published. Although the period of revision of articles is acceptable, the period up to two months is certainly not long, the goal is to reduce this period. Although the magazine in mentioned field found its place, although it is indexed in numerous bases, including: PubMed, PubMed Central, SCOPUS, EMBASE, EBSCO, etc. The main goal for next year is that the magazine becomes part of the Web of Science. Imperative is further internationalization of the magazine.

    Sabemos que la mínima porción de la materia es el átomo, que tiene una composición compleja, que no es del caso estudiar. Los átomos pueden existir aislados y estar en lo que llamamos estado iónico. Si los átomos se juntan, forman moléculas, y su existencia constituye el estado molecular. Si las moléculas se juntan, forman complejos más grandes y tendremos las micelas, que constituyen el estado coloidal.

    Hasta aquí nuestros conocimientos nos son familiares, triviales. Pero hay un estado más complejo, en el cual entra materia en estado iónico, molecular y coloidal entrelazados entre sí, con propiedades totalmente diferentes. La materia en este estado adquiere caracteres extraordinarios tales como el de crecer, reproducirse, independizarse de las leyes físicas, puede autorregular su composición química, autorregular sus manifestaciones físicas, reaccionar ante los estímulos más variados, puede llegar hasta alturas inconcebibles integrando ideas.

    Full Text Available Translation memories (TMs, as part of Computer Assisted Translation (CAT tools, support translators reusing portions of formerly translated text. Fencing books are good candidates for using TMs due to the high number of repeated terms. Medieval texts suffer a number of drawbacks that make hard even “simple” rewording to the modern version of the same language. The analyzed difficulties are: lack of systematic spelling, unusual word orders and typos in the original. A hypothesis is made and verified that even simple modernization increases legibility and it is feasible, also it is worthwhile to apply translation memories due to the numerous and even extremely long repeated terms. Therefore, methods and algorithms are presented 1. for automated transcription of medieval texts (when a limited training set is available, and 2. collection of repeated patterns. The efficiency of the algorithms is analyzed for recall and precision.

  8. Imagining Place and Moralizing Space: Jerusalem at Medieval Westminster

    Directory of Open Access Journals (Sweden)

    Laura Slater

    2017-06-01

    Full Text Available Monuments and landscape ensembles across medieval Europe recreated the Christian holy places of Jerusalem for local devotees. Contemporary legends surrounding the death of King Henry IV in 1413, who died in the Jerusalem Chamber in the abbot’s house at Westminster Abbey, place the room firmly within this cultural tradition. In the sixteenth century, a neighbouring Jericho Parlour was built. This paper highlights the political significances of such “recreated Jerusalem” sites: in contrast to the religious and demographic diversity found in the earthly city, and in connection with European crusading and imperial ambitions. Exploring the “death in Jerusalem” topos in detail, it argues that the Jerusalem Chamber should not be understood as a recreated holy place. Instead, the links to the Holy Land found in the abbot’s house form part of an imaginative reinvention of space within medieval Westminster, deliberately intended to provoke moral admonition and self-scrutiny in its users.

    ABSTRACT Shotgun metagenomics provides a powerful assumption-free approach to the recovery of pathogen genomes from contemporary and historical material. We sequenced the metagenome of a calcified nodule from the skeleton of a 14th-century middle-aged male excavated from the medieval Sardinian settlement of Geridu. We obtained 6.5-fold coverage of a Brucella melitensis genome. Sequence reads from this genome showed signatures typical of ancient or aged DNA. Despite the relatively low coverage, we were able to use information from single-nucleotide polymorphisms to place the medieval pathogen genome within a clade of B. melitensis strains that included the well-studied Ether strain and two other recent Italian isolates. We confirmed this placement using information from deletions and IS711 insertions. We conclude that metagenomics stands ready to document past and present infections, shedding light on the emergence, evolution, and spread of microbial pathogens. PMID:25028426

    Development of dental abnormalities due to improper occlusal wear is common among modern domestic horses. This phenomenon often is attributed to jaw conformation. Rostral mandibular hooks may develop in horses with underjet or mandibular prognathism, a condition where the lower jaw protrudes forward, beyond the upper jaw. Less abrasive diet, free of phytoliths and matrix-like plant fibers, also may promote enamel and focal overgrowths of equine dentition. Here we report a rostral mandibular hook in a lower premolar tooth of a medieval horse, found in a spring deposit in Levänluhta, Osthrobothnia, Finland. To our knowledge, this is the first such report from a medieval horse. Copyright © 2017 Elsevier Inc. All rights reserved.

    Has the Antilles Subduction Zone produced thrust or outer-rise earthquakes east of Hispaniola? An affirmative answer is suggested by tiered evidence for overwash 120 km south of the Puerto Rico Trench. The evidence comes from Anegada, British Virgin Islands, 200 km east-northeast of San Juan, Puerto Rico. PREVIOUS FINDINGS* suggested that a medieval overwash event had greater geologic effects at Anegada than did a Lisbon(?) event, and that both events outrank recent storms. The medieval overwash, in AD 1200-1450, dislodged brain corals from a reef, moved them as much as 500 m across a shallow subtidal flat, and scattered them as solitary boulders as much as 1000 m inland. Gentler overwash in 1650-1800, called Lisbon(?) because it may represent the 1755 tsunami, laid down a sheet of sand and island-derived shells as much as 1500 m from the north shore. A recent hurricane of category 4 left no durable geologic record other than sandy fans within 40 m of the south shore. NEW FINDINGS reinforce the ranking medieval > Lisbon(?) > storm: (1) The medieval event washed ashore marine shells that the Lisbon(?) event did not. An articulated marine bivalve (Codakia orbicularis), probably deposited live, is part of an overwash fan 400 m inland from Windlass Bight. The shell dates to the same time window as the medieval coral boulders. Additional articulated Codakia shells and a conch shell adjoin the buried base of one of these coral boulders 1500 m south of the fringing reef from which the coral was probably derived. (2) Lisbon(?) overwash used breaches that the medieval event had cut through beach ridges of the north shore. The re-use is marked by sand: on the muddy floor of a partly filled breach, on an organic soil in another such breach, and on a pre-existing fan south of an area of beach-ridge dissection. The buried organic soil, inset into a old breach, is 500 m inland from an area, near Cow Wreck High Point, where young beach ridges may have been breached for the first

    Interrogations and elections were two branches of Arabic judicial astrology made available in Latin translation to readers in western Europe from the twelfth century. Through an analysis of the theory and practice of interrogations and elections, including the writing of the Jewish astrologer Sahl b. Bishr, this essay considers the extent to which judicial astrology was practiced in the medieval west. Consideration is given to historical examples of interrogations and elections mostly from late medieval English manuscripts. These include the work of John Dunstaple (ca. 1390-1453), the musician and astrologer who is known have served at the court of John, duke of Bedford. On the basis of the relatively small number of surviving historical horoscopes, it is argued that the practice of interrogations and elections lagged behind the theory.

    Medieval European urbanization presents a line of continuity between earlier cities and modern European urban systems. Yet, many of the spatial, political and economic features of medieval European cities were particular to the Middle Ages, and subsequently changed over the Early Modern Period and Industrial Revolution. There is a long tradition of demographic studies estimating the population sizes of medieval European cities, and comparative analyses of these data have shed much light on the long-term evolution of urban systems. However, the next step-to systematically relate the population size of these cities to their spatial and socioeconomic characteristics-has seldom been taken. This raises a series of interesting questions, as both modern and ancient cities have been observed to obey area-population relationships predicted by settlement scaling theory. To address these questions, we analyze a new dataset for the settled area and population of 173 European cities from the early fourteenth century to determine the relationship between population and settled area. To interpret this data, we develop two related models that lead to differing predictions regarding the quantitative form of the population-area relationship, depending on the level of social mixing present in these cities. Our empirical estimates of model parameters show a strong densification of cities with city population size, consistent with patterns in contemporary cities. Although social life in medieval Europe was orchestrated by hierarchical institutions (e.g., guilds, church, municipal organizations), our results show no statistically significant influence of these institutions on agglomeration effects. The similarities between the empirical patterns of settlement relating area to population observed here support the hypothesis that cities throughout history share common principles of organization that self-consistently relate their socioeconomic networks to structured urban spaces.

    Full Text Available In this study, socialization of libraries in Medieval Europe has been examined by means of the growing of cities and movements of ideologies. Cities, as results of economic based changes, caused the apperance of merchantiles in produce and consumption flows. Cities, by selecting an area outside of feudal city walls, and by consisting new living habits which shows differances from village living habits took its place in Medieval Feudal Regime. While cities consist their conceits, conceits consists the specialisatians which identifies the city from the village. Technologic developments, innovations, the movements of different social classes, the changes in produce and consumption models, movements of ideologies; carried Medieval Europe to Enlighment Period after very long and difficult experiements. While the man in “Enlighment Period” ideologically based on rationalism and critical thinking; it realized knowledge as a product of rationalism. That realisation gave start to the socialisation of libraries and books and books which includes the “knowledge” stating with the innovation of press, the gobalization of books and the movements in cities gave speed to the interaction between cultures and effected the extansi-on of knowledge in a positive way. While knowledge was socialized by means of the opportunities of cities, libraries became space which knowledge can easily reachable by society. Cities arosed in Middle ageesand by effecting social structures, they became an indirect effect for reaching of libraries to society and moneyfree service.

    Science.gov (United States)

    Askew, Graham N; Formenti, Federico; Minetti, Alberto E

    2012-02-22

    In Medieval Europe, soldiers wore steel plate armour for protection during warfare. Armour design reflected a trade-off between protection and mobility it offered the wearer. By the fifteenth century, a typical suit of field armour weighed between 30 and 50 kg and was distributed over the entire body. How much wearing armour affected Medieval soldiers' locomotor energetics and biomechanics is unknown. We investigated the mechanics and the energetic cost of locomotion in armour, and determined the effects on physical performance. We found that the net cost of locomotion (C(met)) during armoured walking and running is much more energetically expensive than unloaded locomotion. C(met) for locomotion in armour was 2.1-2.3 times higher for walking, and 1.9 times higher for running when compared with C(met) for unloaded locomotion at the same speed. An important component of the increased energy use results from the extra force that must be generated to support the additional mass. However, the energetic cost of locomotion in armour was also much higher than equivalent trunk loading. This additional cost is mostly explained by the increased energy required to swing the limbs and impaired breathing. Our findings can predict age-associated decline in Medieval soldiers' physical performance, and have potential implications in understanding the outcomes of past European military battles.

    Leprosy was a well-recognized and dreaded disease in medieval Europe. The disease is reported to have reached Germany with the Roman invasion and it was present in Scandinavia in the first centuries AD. This paper estimates and analyzes the frequency of leprosy among adult people buried in one of five medieval cemeteries in the city of Schleswig. Seven different dichotomous osteological lesions indicative of leprosy were analyzed, and it was possible to score at least one of these conditions on 350 adult skeletons (aged 15 or older). The scores were transformed to a statistic indicating the likelihood that the person to whom the skeleton belonged suffered from leprosy. It was found that the frequency of leprosy in the five cemeteries varied between 9 and 44%. Four of the five cemeteries showed frequencies ranging from 35 and 44% and with no statistically significant differences among them. The fifth cemetery showed a significantly lower frequency of leprosy (9%). The distribution of female age at death does not appear to be affected by leprosy status. This means that females experienced a considerably elevated risk of dying once they had contracted leprosy as the disease usually has a mid-adulthood age of onset. In four of the five cemeteries males with leprosy died in higher ages than men without leprosy--in two of the cemeteries the difference was statistically significant. This indicates that leprosy usually added less to the risk of dying among men than among women in medieval Schleswig.

    Despite the well-known history of hypertension research in the modern era, like many other cardiovascular concepts, main points in the medieval concept of this disease and its early management methods remain obscure. This article attempts to make a brief review on the medieval origin of the concept of this disease from the Hidayat of Al-Akhawayni (?-983 AD). This article has reviewed the chapter of "Fi al-Imtela" (About the Fullness) from the Hidβyat al-Muta'allimin fi al-Tibb (The Students' Handbook of Medicine) of Al-Akhawayni. The definition, symptoms and treatments presented for the Imtela are compared with the current knowledge on hypertension. Akhawayni believed that Imtela could result from the excessive amount of blood within the blood vessels. It can manifest with symptoms including the presence of a pulsus magnus, sleepiness, weakness, dyspnea, facial blushing, engorgement of the vessels, thick urine, vascular rupture, and hemorrhagic stroke. He also suggested some ways to manage al-Imtela'. These include recommendations of changes in lifestyle (staying away from anger and sexual intercourse) and dietary program for patients (avoiding the consumption of wine, meat, and pastries, reducing the volume of food in a meal, maintaining a low-energy diet and the dietary usage of spinach and vinegar). Al-Akhawayni's description of "Imtela," despite of its numerous differences with current knowledge of hypertension, can be considered as medieval origin of the concept of hypertension.

  9. Erecting Sex: Hermaphrodites and the Medieval Science of Surgery.

    Science.gov (United States)

    DeVun, Leah

    2015-01-01

    This essay focuses on "hermaphrodites" and the emerging profession of surgery in thirteenth- and fourteenth-century Europe. During this period, surgeons made novel claims about their authority to regulate sexual difference by surgically ''correcting" errant sexual anatomies. Their theories about sex, I argue, drew upon both ancient roots and contemporary conflicts to conceptualize sexual difference in ways that influenced Western Europe for centuries thereafter. I argue that a close examination of medieval surgical texts complicates orthodox narratives in the broader history of sex and sexuality: medieval theorists approached sex in sophisticated and varied manners that belie any simple opposition of modern and premodern paradigms. In addition, because surgical treatments of hermaphrodites in the Middle Ages prefigure in many ways the treatment of atypical sex (a condition now called, controversially, intersex or disorders/differences of sex development) in the modern world, I suggest that the writings of medieval surgeons have the potential to provide new perspectives on our current debates about surgery and sexual difference.

    Late medieval England underwent intensive urbanisation, particularly in its largest city: London. Urban dwellers were exposed to factors such as high population density, elevated risk of infection, unsanitary living conditions and precarious food supplies. To assess whether the urban environment was more detrimental to health than the rural environment, this study compares risks of mortality and survival, as proxies for health, in medieval urban vs rural England. This study uses samples from rural St. Peter's cemetery in Barton-upon-Humber, Lincolnshire (c. 1150-1500) and urban St. Mary Spital cemetery in London (c. 1120-1539). Cox proportional hazards analysis and Kaplan-Meier survival analysis are used to assess differences in mortality and survival between urban and rural environments, including differences between sexes. The results indicate that urban adults faced elevated risks of dying and reductions in survivorship. Specifically, urban females faced elevated risks of dying and reductions in survivorship, while the risks for males were similar in both environments. These results suggest that the effects of urbanisation in medieval England varied by sex. Deleterious conditions associated with urbanisation in London were hazardous for adults, particularly females who may have migrated into London from rural areas for labour opportunities.

    Parasites have been infecting humans throughout our evolution. However, not all people suffered with the same species or to the same intensity throughout this time. Our changing way of life has altered the suitability of humans to infection by each type of parasite. This analysis focuses upon the evidence for parasites from archaeological excavations at medieval sites across Europe. Comparison between the patterns of infection in the medieval period allows us to see how changes in sanitation, herding animals, growing and fertilizing crops, the fishing industry, food preparation and migration all affected human susceptibility to different parasites. We go on to explore how ectoparasites may have spread infectious bacterial diseases, and also consider what medieval medical practitioners thought of parasites and how they tried to treat them. While modern research has shown the use of a toilet decreases the risk of contracting certain intestinal parasites, the evidence for past societies presented here suggests that the invention of latrines had no observable beneficial effects upon intestinal health. This may be because toilets were not sufficiently ubiquitous until the last century, or that the use of fresh human faeces for manuring crops still ensured those parasite species were easily able to reinfect the population.

  12. The Medieval Concept of Music Perception. Hearing, Calculating and Contemplating

    Full Text Available Seeking to indicate the most salient features of the medieval perception of music, we must first of all point to the close relationship between the sensual and intellectual elements. This relationship is most conspicuous in the term "harmonica" introduced in the Latin Middle Ages by Boethius and defined as follows: "harmonica is the faculty of perceiving through senses and the intellect the differences between high and low sounds". The same definition reveals another significant feature of the perception of music, namely, that the importance is attached not to individual sounds, but to the differences or relationships between them, that is to the intervals. Since - in accordance with the Pythagorean tradition, which was a major force in medieval music theory - the relationship between sounds can be expressed numerically, it may therefore be considered in terms of the relationship of two numbers, apart from actual sound and beyond physical time. The question arises whether this concept of music could influence the perception of a medieval listener. For instance, can listening to music be understood as a process which engages both cognitive powers and concerns reducing in some unspecified manner the data perceived and processed by the senses to abstract categories which can be conceived only by the intellect?

  13. Judicial privilgies of Saxons in mixed disputes in Medieval Serbia

    Full Text Available Based on the contemporary testimonies, wealth of the Serbian medieval kings was significantly increased by exploitation of number of precious metal mines that existed in their realm. Beginnings of the mine exploitation in medieval Serbia are related to the settlements of Saxon miners. Saxons were mining experts in medieval Europe who worked in distant mines far away from their homeland Saxony. They worked in this profitable mining business not only in Serbia, but also in Bohemia, Hungary (Transylvania and modern Slovakia and Bosnia. The settlement of Saxons in Serbia occurred in time of the reign of King Stefan Uros I (1234-1276. Although without preserved sources which could directly support this thesis, Serbian historiography advocates that certain privileges were granted to the Roman Catholic Saxons at the time of their migration in orthodox Serbia. It appears that these privileges included self-government, freedom of religion, and mining concessions. Also judicial privileges are often mentioned in historiography especially the right of Saxons to one half of the members of their ethnicity in judicial collegium and jury in the case of a dispute with member of another ethic group. This paper attempts to test the thesis related to composition of mixed courts and juries by applying historical method, and linguistic, systemic and historical interpretation of the sources such as King's Charters issued to Dubrovnik, Dusan's Code and Despot Stefan's Mining Code.

  14. Ancient and medieval Iberia seen through glass: An archaeometric perspective

    The study of ancient and medieval glasses has identified distinct compositional groups as a result of the chemical characteristics of the raw materials used for its production. Archaeometric analysis can determine the provenance of the glass, and has demonstrated a large-scale production and commercialisation of raw glass throughout the Mediterranean during the ancient and medieval periods. Secondary workshops on the Iberian Peninsula imported raw glass from the Near East for the better part of the first millennium CE, following a similar pattern observed elsewhere in the Mediterranean region. However, there are some indications that point to a local production of glass and that deserve further investigation. In the ninth century, natron glass was replaced in al-Ándalus by plant ash and lead-rich glass that may represent a local production. Little is known about the production or use of glass in the Christian parts of the peninsula during this period. The increasing volume of analytical data on Spanish glass demonstrates the potential of an archaeometric approach to shed light not only on the production and trade of glass on the Iberian Peninsula but also on the ancient and medieval economy more generally.

    Full Text Available Objectives This study was performed to investigate the effects of different intracanal medicaments on chemical structure and microhardness of dentin. Materials and Methods Fifty human dentin discs were obtained from intact third molars and randomly assigned into two control groups and three treatment groups. The first control group received no treatment. The second control group (no medicament group was irrigated with sodium hypochlorite (NaOCl, stored in humid environment for four weeks and then irrigated with ethylenediaminetetraacetic acid (EDTA. The three treatment groups were irrigated with NaOCl, treated for four weeks with either 1 g/mL triple antibiotic paste (TAP, 1 mg/mL methylcellulose-based triple antibiotic paste (DTAP, or calcium hydroxide [Ca(OH2] and finally irrigated with EDTA. After treatment, one half of each dentin disc was subjected to Vickers microhardness (n = 10 per group and the other half was used to evaluate the chemical structure (phosphate/amide I ratio of treated dentin utilizing attenuated total reflection Fourier transform infrared spectroscopy (n = 5 per group. One-way ANOVA followed by Fisher's least significant difference were used for statistical analyses. Results Dentin discs treated with different intracanal medicaments and those treated with NaOCl + EDTA showed significant reduction in microhardness (p < 0.0001 and phosphate/amide I ratio (p < 0.05 compared to no treatment control dentin. Furthermore, dentin discs treated with TAP had significantly lower microhardness (p < 0.0001 and phosphate/amide I ratio (p < 0.0001 compared to all other groups. Conclusions The use of DTAP or Ca(OH2 medicaments during endodontic regeneration may cause significantly less microhardness reduction and superficial demineralization of dentin compared to the use of TAP.

    Background and aims Integrated management of childhood illness (IMCI) is an EBM guideline prepared by WHO and UNICEF guideline in primary health care for better assessment and management in pediatrics. The study was carried out to demonstrate the reduction of medicament prescription by the application of IMCI program in two months up to five years old children presenting with an infectious disease. Methods Before and after study was carried out in July 2012 at a pediatric E.R children who met with the inclusion criteria were rolled in: ▸ Consulting for infectious disease. ▸ With no anterior treatment with antibiotics. ▸ No need of hospitalization. In total 112 patients were assessed separately by two groups of doctors (classical approach vs. IMCI guideline). The two prescriptions of each patient were analyzed using Mac Nemar, comparison of proportion tests. Results 112 patients (64 boys, 48 girls) with cough, diarrhea, sore throat, otalgia and fever were studied. In total 280 medicaments were prescribed firstly vs. 160 medicaments with IMCI guideline (P<0.0001). There were 103 oral antibiotics prescribed vs. 28 with IMCI guideline (P<0.0001). There were 20 intra muscular injections prescribed (15 antibiotics) vs. 9 with IMCI guideline (P<0.02). Only 37 antibiotics were justified vs. 82 non-justified (p<0.0001). Conclusion the assessment and management by IMCI program for children age 2 months up to 5 years in outpatient clinic may contribute for a better prescription with a significant reduction in total medicament prescribed, in oral antibiotics and intra muscular injections.

    Full Text Available Gynura medica leaf extract contains significant amounts of flavonols and phenolic acids and exhibits powerful hypoglycemic activity against diabetic rats in vivo. However, the hypoglycemic active constituents that exist in the plant have not been fully elaborated. The purpose of this study is to isolate and elaborate the hypoglycemic activity compounds against inhibition the yeast α-glucosidase in vitro. Seven phenolic compounds including five flavonols and two phenolic acids were isolated from the leaf of G. medica. Their structures were identified by the extensive NMR and mass spectral analyses as: kaempferol (1, quercetin (2, kaempferol-3-O-β-D-glucopyranoside (3, kaempferol-3-O-rutinoside (4, rutin (5, chlorogenic acid (6 and 3,5-dicaffeoylquinic acid methyl ester (7. All of the compounds except 1 and 3 were isolated for the first time from G. medica. Compounds 1–7 were also assayed for their hypoglycemic activity against yeast α-glucosidase in vitro. All of the compounds except 1 and 6 showed good yeast α-glucosidase inhibitory activity with the IC50 values of 1.67 mg/mL, 1.46 mg/mL, 0.38 mg/mL, 0.10 mg/mL and 0.53 mg/mL, respectively.

    2010-09-01

    The aim of this study was to investigate the antimicrobial effect of endodontic medicaments and their bases in the presence of dentine powder. The medicaments tested were Ledermix paste, Pulpdent paste, a 50:50 combination of the Pulpdent:Ledermix and their bases. The test organism was Enterococcus faecalis ATCC 29212. The presence or absence of dentine was examined as well as the effect of autoclaving dentine. Serial dilutions of samples at 1 hour, 1 day and 3 days were used for colony counting. The effects of dentine powder on pH for saturated Ca(OH)2 solution and Pulpdent paste at 1 hour and 24 hours were also measured. Pulpdent and the 50:50 combination of Pulpdent:Ledermix completely inhibited the growth of E. faecalis from 1 hour onwards, and these results were not affected by the presence/absence of dentine powder, pre-incubation period, timing of autoclaving, or exposure time. Saturated solutions of Ca(OH)2 are prone to inactivation by dentine powder unlike Pulpdent paste. Ledermix paste took 3 days to exert a significant effect on the growth of E. faecalis. In this laboratory study, both Pulpdent and the 50:50 mixture of Pulpdent with Ledermix were effective medicaments against E. faecalis in the presence of dentine powder.

    Polypharmacy is the consequence of multimorbidity. Both phenomena may cause functional limitations and/or frailty and/or care dependency in older people. In the human body, a medicament undergoes at least 3 important actions: absorption, distribution and elimination. These actions may proceed aberrantly in older people. Following interaction with receptors, a medicament triggers a chain reaction in the human body. The receptors and each link of the chain reaction may be subject to changes due to diseases as well as ageing. This, particularly, is the case with regard to medications directed towards the central nervous system and the cardiovascular system. Furthermore, interactions may occur between various medications mutually and between medications on the one hand and on the other hand food and water intake, self-medication with herbs, and diseases. Moreover, older people usually experience more adverse effects of medications when compared to younger people. This is due to altered body actions and reactions, polypharmacy and the many possible interactions. In older people, utilisation and intake of medications often give rise to problems that can be divided into medicament-related, patient-related, care- and care provider-related and other problems.

    The purpose of this in vitro study was to evaluate the effects of intracanal medicaments commonly used in endodontic regeneration on the survival of human dental pulp cells (DPCs). DPCs were cultured and exposed to either no medicament treatment or low concentrations (0.3-5 mg ml(-1) ) of calcium hydroxide [Ca(OH)2 ], triple antibiotic paste (TAP), or double antibiotic paste (DAP) for 3 days. After that, toxicity to the DPCs was determined by lactate dehydrogenase activity assays (LDH) and cell proliferation was measured by colorimetric assays (WST-1). Two-way anova followed by Fisher's protected least significant differences was used for statistical analyses (α = 0.05). The group-by-concentration interactions were significant for the LDH and WST-1 assays (P medicaments tested in this study were not cytotoxic in cultured cells. However, these concentrations are much lower than the concentrations that have been advocated in endodontic regeneration. Furthermore, the negative effects of TAP on DPCs were detected at lower concentrations by using the WST-1 assays than by measuring the LDH release. © 2014 John Wiley & Sons A/S.

    Many studies have investigated the effectiveness of root canal irrigants and medicaments against Enterococcus faecalis. The aim of this study was to compare the efficacy of commonly used medicaments against E. faecalis cultured as a biofilm on dentine substrate. An E. faecalis biofilm was established on human dentine slices using a continuous flow cell. Each test medicament (Ledermix, Ca(OH) 2 , Odontopaste, 0.2% chlorhexidine and 50:50 combinations of Ledermix/Ca(OH) 2 and Odontopaste/Ca(OH) 2 ) was introduced into the flow cell and biofilms were harvested and quantitated by determining cellular protein. Cellular viability was determined using serial plating and the number of colony-forming units was normalized against cellular protein to allow treatment protocols to be compared. Qualitative scanning electron microscopy analyses of the biofilm were performed after a 48-h exposure to each test agent. Sodium hypochlorite achieved total bacterial elimination. Ledermix and Odontopaste had no significant effect on the E. faecalis biofilm. Ca(OH) 2 and 50:50 combinations of Ca(OH) 2 /Ledermix or Ca(OH) 2 /Odontopaste reduced the viability by more than 99% while 0.2% chlorhexidine reduced bacterial numbers by 97%. Sodium hypochlorite remains the gold standard for bacterial elimination in root canal therapy. However, Ca(OH) 2 in isolation and combined with Ledermix, and Odontopaste was highly effective in reducing bacterial viability. © 2017 Australian Dental Association.

    Pulpotomy is the most common treatment to preserve vitality of cariously exposed molars. Various pulpotomy medicaments used should be antimicrobial, should help in healing without damaging surrounding tissue, and should not affect eruption of permanent teeth. Thus, this study was conducted to evaluate and compare the clinical and radiographic outcomes of formocresol (FC) and sodium hypochlorite (NaOCl) in primary molars. The aim of this randomized study was to compare the clinical and radiographic success rate of FC and 5% NaOCl as a pulpotomy medicament in primary molars. Forty children aged 4 to 9 years with primary carious molar were selected and randomly assigned into two groups: FC and NaOCl. Pulpotomy procedure was then performed followed by restoration with stainless steel crowns. Clinical and radiographic evaluation was done at an interval of 3 to 6 months. Clinical success rate at 3 and 6 months was 100% for both groups. Radiographic success rate for FC was 95% at 3 months and 90% at 6 months, whereas for NaOCl, it was 90% at 3 months and 85% at 6 months. Based on this study, result of 5% NaOCl and FC showed no significant difference in their success rate. Hence, NaOCl can be used as pulpotomy medicament; however, further clinical trials with long follow-up period are required. Sodium hypochlorite is a potential clinical substitute of FC for vital pulpotomy treatment in primary teeth because of its exceptional biological compatibility and to evade carcinogenic effect of FC.

    Diabetes Mellitus is a common metabolic disorder presenting increased amounts of serum glucose and will cover 5.4% of population by year 2025. Accordingly, this review was performed to gather and discuss the stand points on diagnosis, pathophysiology, non-pharmacological therapy and drug management of diabetes this disorder as described in medieval Persian medicine. To this, reports on diabetes were collected and analyzed from selected medical and pharmaceutical textbooks of Traditional Persian Medicine. A search on databases as Pubmed, Sciencedirect, Scopus and Google scholar was also performed to reconfirm the Anti diabetic activities of reported herbs. The term, Ziabites, was used to describe what is now spoken as diabetes. It was reported that Ziabites, is highly associated with kidney function. Etiologically, Ziabites was characterized as kidney hot or cold dystemperament as well as diffusion of fluid from other organs such as liver and intestines into the kidneys. This disorder was categorized into main types as hot (Ziabites-e-har) and cold (Ziabites-e-barid) as well as sweet urine (Bole-e-shirin). Most medieval cite signs of Ziabites were remarked as unusual and excessive thirst, frequent urination and polydipsia. On the management, life style modification and observing the essential rules of prevention in Persian medicine as well as herbal therapy and special simple manipulations were recommended. Current investigation was done to clarify the knowledge of medieval scientists on diabetes and related interventions. Reported remedies which are based on centuries of experience might be of beneficial for- further studies to the management of diabetes.

  16. The state of research on church chant in medieval Serbia

    Full Text Available The Byzantine-musicological studies in Serbia during the last few decades have been at an unsatisfactory level. The fact that Serbian musicologists have not exhibited much interest in exploring this research area could be somewhat justified by the fact that its scope for new studies might seem limited. The efforts aimed towards reconstructing and ‘resounding’ the medieval liturgical melodies based on the anagogic sources (the primary sources - notated manuscripts are very deficient seems, at first glance, discouraging, even futile. Nevertheless, the conditions for systematic research do exist, all the more because the current knowledge on music paleography, rhythmic and scale characteristics of Byzantine church chant has considerably changed the previous inquiry that had been limited to a few, although very precious musical pieces of only three known Serbian fifteenth-century composers - Ishaia, Nikola and Stefan. After a brief account on the topics and issues that have, until now, been in the scholarlyfocus, I draw attention to what has been done and what is currently underway in the research on Serbian medieval chant, while also indicating the areas that could be of greater interest for future explorations. I pay special critical attention to certain conclusions and methodological methods applied to the notated manuscripts that deal with liturgical music practice in medieval Serbia. According to some new findings in the field of Byzantine musicology, a new critical reading of available sources is necessary. Becoming acquainted with the earlier false approaches and conclusions made in haste and without particular evidence could be of significant help and serve as an important impulse for young researchers to get involved with explorations of Serbian music past.

    Full Text Available The study tests the relationship between motivation, satisfaction, and loyalty using a structural equation model. Data have been collected through a questionnaire applied to visitors attending a local festival, Castro Marim Medieval Fair, which hosts every year between 45.000 and 60.000 visitors. Results show that satisfaction towards controlled variables of the event within the venue’s boundaries, such as animation, gastronomy, and handicraft, influences visitors’ overall satisfaction towards the event. On the other hand, they also reveal a direct relationship between overall satisfaction and loyalty. The study contributes to a better understanding of visitors’ behaviour and provides useful guidance to festival ideation and design.

  7. Saxon Obsequies: the Early Medieval Archaeology of Richard Cornwallis Neville

    Directory of Open Access Journals (Sweden)

    Howard Williams

    2013-04-01

    Full Text Available This paper investigates the origins of British Anglo-Saxon archaeology by focusing on the work of one early Victorian archaeologist: Richard Cornwallis Neville. The seemingly descriptive and parochial nature of Neville’s archaeological pursuits, together with the attention he afforded to Romano-British remains, has impeded due recognition, and critical scrutiny, of his contributions to the development of early Medieval burial archaeology. Using his archaeological publications as source material, I will show how Neville’s interpretations of Saxon graves were a form of memory work, defining his personal, familial and martial identity in relation to the landscape and locality of his aristocratic home at Audley End, near Saffron Walden, Essex. Subsequently, I argue that Neville’s prehistoric and Romano-British discoveries reveal his repeated concern with the end of Roman Britain and its barbarian successors. Finally, embodied within Neville’s descriptions of early Medieval graves and their location we can identify a pervasive Anglo-Saxonism. Together these strands of argument combine to reveal how, for Neville, Saxon graves constituted a hitherto unwritten first chapter of English history that could be elucidated through material culture and landscape.

  8. An Atlas of Medieval Combs from Northern Europe

    2011-07-01

    Full Text Available As an aid to understanding chronology, economics, identity and culture contact, the early medieval bone/antler hair-comb is an under-exploited resource, despite the existence of an extensive literature borne out of a long-standing tradition of empirical research. Such research has been undertaken according to diverse traditions, is scattered amongst site reports and grey literature, regional, national, and international journals, and is published in a number of different languages. The present article provides a general synthesis of this data, together with the author's personal research, situated within a broad view of chronology and geography. It presents the author's classification of early medieval composite combs, and applies this in a review of comb typology in space and time. It makes use of recently excavated material from little-known and unpublished sites, as well as the classic studies of familiar towns and 'emporia'. The atlas is intended for use as a reference piece that may be accessed according to need, and read in a non-linear fashion. Thus, it may act as a first port-of-call for scholars researching the material culture of a particular spatio-temporal context, while simultaneously facilitating rapid characterisation of freshly excavated finds material. It should provide a useful complement to recent and ongoing question-oriented research on combs.

    Berlin originated from the two twin cities Berlin and Cölln, which both were founded at the beginning of the 13th century. However the real date of their foundation as well as the origin of the first settlers is still unknown. On the Berlin site the historic city center is still visible in the Nikolaiviertel, but the medieval origin of Cölln disappeared almost completely. In 2007 a large scale excavation, which comprised an area of about 1700m(2) of the historical center of the St. Peters church, recovers the remains of Cölln's first citizens and span a period of 500 years of medieval population. Here we present the first genetic analysis of a fivefold children's burial from excavations in Berlin. The genetic data unveiled next to ancestry and eye color data also the kinship and the gender of the five individuals. Together with the archeological context the new gained information help to shed more light on the possible reasons for this burial. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

    Morphological and ultrastructural data from archaeological human bones are scarce, particularly data that have been correlated with information on the preservation of molecules such as DNA. Here we examine the bone structure of macroscopically well-preserved medieval human skeletons by transmission electron microscopy and immunohistochemistry, and the quantity and quality of DNA extracted from these skeletons. DNA technology has been increasingly used for analyzing physical evidence in archaeological forensics; however, the isolation of ancient DNA is difficult since it is highly degraded, extraction yields are low and the co-extraction of PCR inhibitors is a problem. We adapted and optimised a method that is frequently used for isolating DNA from modern samples, Chelex(®) 100 (Bio-Rad) extraction, for isolating DNA from archaeological human bones and teeth. The isolated DNA was analysed by real-time PCR using primers targeting the sex determining region on the Y chromosome (SRY) and STR typing using the AmpFlSTR(®) Identifiler PCR Amplification kit. Our results clearly show the preservation of bone matrix in medieval bones and the presence of intact osteocytes with well preserved encapsulated nuclei. In addition, we show how effective Chelex(®) 100 is for isolating ancient DNA from archaeological bones and teeth. This optimised method is suitable for STR typing using kits aimed specifically at degraded and difficult DNA templates since amplicons of up to 250bp were successfully amplified.

  11. Symptom and Surface: Disruptive Deafness and Medieval Medical Authority.

    Science.gov (United States)

    Hsy, Jonathan

    2016-12-01

    This essay examines constructions of deafness in medieval culture, exploring how deaf experience disrupts authoritative discourses in three textual genres: medical treatise, literary fiction, and autobiographical writing. Medical manuals often present deafness as a physical defect, yet they also suggest how social conditions for deaf people can be transformed in lieu of treatment protocols. Fictional narratives tend to associate deafness with sin or social stigma, but they can also imagine deaf experience with a remarkable degree of sympathy and nuance. Autobiographical writing by deaf authors most vividly challenges diagnostic models of disability, exploring generative forms of perception that deafness can foster. In tracing the disruptive force that deaf experience exerts on perceived notions of textual authority, this essay reveals how medieval culture critiqued the diagnostic power of medical practitioners. Deafness does not simply function as a symptom of an individual problem or a metaphor for a spiritual or social condition; rather, deafness is a transformative capacity affording new modes of knowing self and other.

We have visited numismatists funds from principal Galician museums and institutions who kindly opened us their doors, discovering, on occasions, medieval coins that had gone unnoticed or other badly catalogued. Sometimes, however, the cataloguing was perfect and the metrological work and photography was already done. This search was necessary because of the scarce published medieval coin finds for Northwest Spain, insufficient to draw firm conclusions. It has allowed us to conclude, among other things, that coins and money are already very present in rural areas in XII and XIII Galician middle ages, or that Portuguese coins had immense presence in medieval XIV and XV Galicia. Nevertheless, we know that recent archaeological activity in Galicia is discovering new specimens that will increase our knowledge, allowing us to know if there has been or not coin survival in several decades or if depression of the use of money after the fall of the Roman Empire has been so intense as it seems up to the recovery of XII century.El presente trabajo pretende dar a conocer el material numismático medieval hallado en Galicia que aún permanecía inédito fuera de las instituciones donde se preserva, conscientes de la importancia del conocimiento de todos los datos posibles para la interpretación histórica, siendo los hallazgos de moneda el más fiel testimonio, junto a la documentación, del uso y circulación de la moneda en todas épocas.

    To develop discriminant functions for sex estimation on medieval Croatian population and test their application on contemporary Croatian population. From a total of 519 skeletons, we chose 84 adult excellently preserved skeletons free of antemortem or postmortem changes and took all standard measurements. Sex was estimated/determined using standard anthropological procedures and ancient DNA (amelogenin analysis) where pelvis was insufficiently preserved or where sex morphological indicators were not consistent. We explored which measurements showed sexual dimorphism and used them for developing univariate and multivariate discriminant functions for sex estimation. We included only those functions that reached accuracy rate ≥80%. We tested the applicability of developed functions on modern Croatian sample (n=37). From 69 standard skeletal measurements used in this study, 56 of them showed statistically significant sexual dimorphism (74.7%). We developed five univariate discriminant functions with classification rate 80.6%-85.2% and seven multivariate discriminant functions with an accuracy rate of 81.8%-93.0%. When tested on the modern population functions showed classification rates 74.1%-100%, and ten of them reached aimed accuracy rate. Females showed higher classified in the mediaeval populations, whereas males were better classification rates in the modern populations. Developed discriminant functions are sufficiently accurate for reliable sex estimation in both medieval Croatian population and modern Croatian samples and may be used in forensic settings. The methodological issues that emerged regarding the importance of considering external factors in development and application of discriminant functions for sex estimation should be further explored.

    To discuss the neuropsychiatric phenomena described in Cantigas de Santa Maria (Canticles of St. Mary [CSM]). CSM is a collection of 427 canticles composed in Galician-Portuguese between 1252 and 1284 at the Court of King Alfonso X the Wise of Spain (1221-1284). The canticles (of which 9 are repeated) include devotional and liturgical poems and 353 narrative stories consisting mainly of depictions of Marian miracles. Most are set to music and many are illustrated. We reviewed the canticles for description of miracles and other neuropsychiatric phenomena. Two neurologists reached a consensus about the descriptions. Of the 353 miracles, 279 medically relevant facts (from 187 canticles) and 25 instances of resurrection were reported. Possible neuropsychiatric conditions were described in 98 canticles. Physicians were mentioned in 16 narratives. The most common neurologic conditions detailed were blindness (n = 17), dystonia, weakness, and deformities (n = 20). Other common conditions included psychosis (n = 15), speech disorder/deaf-mutism (n = 12), infections (n = 15), sexual dysfunction/infertility/obstetrical-gynecologic issues (n = 18), head trauma (n = 5), ergotism/St. Anthony's fire (n = 7), and others. There were 9 instances of prodromic mystical experiences/hallucinations heralding death. While limited by retrospection and interpretation of neuropsychiatric phenomena in the medieval context, these short accounts are among the first descriptions of neuropsychiatric conditions in early Portuguese/Galician. They reflect how medieval societies used rational and irrational approaches to understand occurrences in their lives. © 2015 American Academy of Neurology.

    High-resolution manganese and iron K-edges XANES spectra were collected on several samples of archeological interest: prehistorical paintings and medieval glasses. XANES spectra were collected at the ID21 facility (ESRF, Grenoble, France) using a micro-beam device and at the 11-2 beamline (SSRL, Stanford, USA) using a submillimetric beam. The medieval glasses studied are from gothic glass windows from Normandy (XIVth century). The aim of this study is to help understand the chemical durability of these materials, exposed to weathering since the XIVth century. They are used as analogues of weathered glasses used to dump metallic wastes. These glasses show surficial enrichment in manganese, due to its oxidation from II (glass) to III/IV (surface), which precipitates as amorphous oxy-hydroxides. Similarly, iron is oxidized on the surface and forms ferrihydrite-type aggregates. The prehistorical paintings are from Lascaux and Ekain (Basque country). We choose in that study the black ones, rich in manganese to search for potential evidences of some 'savoir-faire' that the Paleolithic men could have used to realize their paint in rock art, as shown earlier for Fe-bearing pigments. A large number of highly valuable samples, micrometric scaled, were extracted from these frescoes and show large variation in the mineralogical nature of the black pigments used, from an amorphous psilomelane-type to a well-crystallized pyrolusite. Correlation with the crystals morphology helps understanding the know-how of these early artists.

  1. Skin pathology and medical prognosis in medieval Europe: the secrets of Hippocrates.

    Science.gov (United States)

    Ackerman Smoller, L

    2000-12-01

    This article analyzes a medieval text known as The Secrets of Hippocrates. Neither secret (because of its wide circulation in manuscript and print) nor by Hippocrates, the work offered readers a means of offering a prognosis of impending death based on observable signs on the skin. Although the aphorisms that make up the text make little sense in a modern medical understanding, the Secrets of Hippocrates fits well within three medieval traditions: the tradition of secrets literature, the medieval medical tradition, and the tradition of medieval Christian views about the body. First, like other books of secrets, a genre to whose conventions the text closely adheres, the Secrets of Hippocrates offered a shortcut to socially useful knowledge: the ability to offer an accurate medical prognosis. Second, the treatise corresponded to the medieval physician's concern for the so-called nonnaturals, such as diet and exercise. Third, it fit with a medieval Christian notion that sickness and sin were related, as were sin and ugliness. Just as a leper's deformities were a window to his sinful soul, so skin pathologies could clue a medieval physician to the lethal disease hidden inside the body.

    A collection of nodule isolates from Medicago polymorpha obtained from southern and central Portugal was evaluated by M13-PCR fingerprinting and hierarchical cluster analysis. Several genomic clusters were obtained which, by 16S rRNA gene sequencing of selected representatives, were shown to be associated with particular taxonomic groups of rhizobia and other soil bacteria. The method provided a clear separation between rhizobia and co-isolated non-symbiotic soil contaminants. Ten M13-PCR groups were assigned to Sinorhizobium (Ensifer) medicae and included all isolates responsible for the formation of nitrogen-fixing nodules upon re-inoculation of M. polymorpha test-plants. In addition, enterobacterial repetitive intergenic consensus (ERIC)-PCR fingerprinting indicated a high genomic heterogeneity within the major M13- PCR clusters of S. medicae isolates. Based on nucleotide sequence data of an M13-PCR amplicon of ca. 1500 bp, observed only in S. medicae isolates and spanning locus Smed_3707 to Smed_3709 from the pSMED01 plasmid sequence of S. medicae WSM419 genome's sequence, a pair of PCR primers was designed and used for direct PCR amplification of a 1399-bp sequence within this fragment. Additional in silico and in vitro experiments, as well as phylogenetic analysis, confirmed the specificity of this primer combination and therefore the reliability of this approach in the prompt identification of S. medicae isolates and their distinction from other soil bacteria.

  3. Patterns and prevalence of violence-related skull trauma in medieval London.

    Krakowka, Kathryn

    2017-11-01

    This study aims to identify the patterns and prevalence of violence-related skull trauma (including the cranium and mandible) among a large sample of skeletons from medieval London (1050-1550 AD). In total, data from 399 skulls, representing six different sites from across medieval London, were analyzed for evidence of trauma and assessed for the likelihood that it was caused by violence. The sites include the three parish cemeteries of St Nicholas Shambles (GPO75), St Lawrence Jewry (GYE92), and St Benet Sherehog (ONE94); the two monastic houses of London Blackfriars (PIC87) and St Mary Graces (MIN86); and the early inmate cemetery from the medieval hospital of St Mary Spital (NRT85). The overall findings suggest that violence affected all aspects of medieval London society, but how that violence was characterized largely depended on sex and burial location. Specifically, males from the lay cemeteries appear to have been the demographic most affected by violence-related skull injuries, particularly blunt force trauma to the cranial vault. Using both archaeological and historical evidence, the results suggest that violence in medieval London may have been more prevalent than in other parts of medieval England, particularly rural environments, but similar to other parts of medieval Europe. However, more studies focusing on medieval trauma, and violence specifically, need to be carried out to further strengthen these results. In particular, males from the lay cemeteries were disproportionately affected by violence-related trauma, especially blunt force trauma. It perhaps indicates a means of informal conflict resolution as those of lower status did not always have the newly established medieval legal system available to them. © 2017 Wiley Periodicals, Inc.

  4. Frail or hale: Skeletal frailty indices in Medieval London skeletons.

    Marklein, Kathryn E; Crews, Douglas E

    2017-01-01

    To broaden bioarchaeological applicability of skeletal frailty indices (SFIs) and increase sample size, we propose indices with fewer biomarkers (2-11 non-metric biomarkers) and compare these reduced biomarker SFIs to the original metric/non-metric 13-biomarker SFI. From the 2-11-biomarker SFIs, we choose the index with the fewest biomarkers (6-biomarker SFI), which still maintains the statistical robusticity of a 13-biomarker SFI, and apply this index to the same Medieval monastic and nonmonastic populations, albeit with an increased sample size. For this increased monastic and nonmonastic sample, we also propose and implement a 4-biomarker SFI, comprised of biomarkers from each of four stressor categories, and compare these SFI distributions with those of the non-metric biomarker SFIs. From the Museum of London WORD database, we tabulate multiple SFIs (2- to 13-biomarkers) for Medieval monastic and nonmonastic samples (N = 134). We evaluate associations between these ten non-metric SFIs and the 13-biomarker SFI using Spearman's correlation coefficients. Subsequently, we test non-metric 6-biomarker and 4-biomarker SFI distributions for associations with cemetery, age, and sex using Analysis of Variance/Covariance (ANOVA/ANCOVA) on larger samples from the monastic and nonmonastic cemeteries (N = 517). For Medieval samples, Spearman's correlation coefficients show a significant association between the 13-biomarker SFI and all non-metric SFIs. Utilizing a 6-biomarker and parsimonious 4-biomarker SFI, we increase the nonmonastic and monastic samples and demonstrate significant lifestyle and sex differences in frailty that were not observed in the original, smaller sample. Results from the 6-biomarker and parsimonious 4-biomarker SFIs generally indicate similarities in means, explained variation (R2), and associated P-values (ANOVA/ANCOVA) within and between nonmonastic and monastic samples. We show that non-metric reduced biomarker SFIs provide alternative indices for

    River response to strong earthquake shaking in mountainous terrain often entails the flushing of sediments delivered by widespread co-seismic landsliding. Detailed mass-balance studies following major earthquakes in China, Taiwan, and New Zealand suggest fluvial recovery times ranging from several years to decades. We report a detailed chronology of earthquake-induced valley fills in the Pokhara region of western-central Nepal, and demonstrate that rivers continue to adjust to several large medieval earthquakes to the present day, thus challenging the notion of transient fluvial response to seismic disturbance. The Pokhara valley features one of the largest and most extensively dated sedimentary records of earthquake-triggered sedimentation in the Himalayas, and independently augments paleo-seismological archives obtained mainly from fault trenches and historic documents. New radiocarbon dates from the catastrophically deposited Pokhara Formation document multiple phases of extremely high geomorphic activity between ˜700 and ˜1700 AD, preserved in thick sequences of alternating fluvial conglomerates, massive mud and silt beds, and cohesive debris-flow deposits. These dated fan-marginal slackwater sediments indicate pronounced sediment pulses in the wake of at least three large medieval earthquakes in ˜1100, 1255, and 1344 AD. We combine these dates with digital elevation models, geological maps, differential GPS data, and sediment logs to estimate the extent of these three pulses that are characterized by sedimentation rates of ˜200 mm yr-1 and peak rates as high as 1,000 mm yr-1. Some 5.5 to 9 km3 of material infilled the pre-existing topography, and is now prone to ongoing fluvial dissection along major canyons. Contemporary river incision into the Pokhara Formation is rapid (120-170 mm yr-1), triggering widespread bank erosion, channel changes, and very high sediment yields of the order of 103 to 105 t km-2 yr-1, that by far outweigh bedrock denudation rates

    Full Text Available The determination of bacterial susceptibility to intracanal medicaments is a necessity. Nevertheless, few studies utilize the proper methodology to carry out that evaluation with anaerobes. In this study, the steps of a broth dilution method, carried out in microplates (microdilution and tubes (macrodilution, to test the effect of traditional intracanal medicaments on anaerobic bacteria are described. The results are presented as values of minimal inhibitory and bactericidal concentrations (MIC and MBC. Standardized inocula of the anaerobic bacteria Prevotella nigrescens (ATCC 33563, Fusobacterium nucleatum (ATCC 25586 and Clostridium perfringens (ATCC 13124, in reinforced Clostridium medium (RCM and supplemented Brucella broth, were submitted to different concentrations of calcium hydroxide, chlorhexidine digluconate, camphorated paramonochlorophenol and formocresol solutions. The drugs were diluted in the same culture broths, in microplates and tubes, and were then incubated in anaerobiosis jars at 37ºC for 48 or 96 hours. The determination of MICs was carried out through visual and spectrophotometric readings, and the determination of MBCs, through the plating of aliquots on RCM-blood agar. For that kind of study, the macromethod with spectrophotometric reading should be the natural choice. MICs and MBCs obtained with the macromethod were compatible with the known clinical performance of the studied medications, and the values varied according to the bacteria and culture media employed. RCM was the most effective medium and C. perfringens, the most resistant microorganism.

    Objective: To compare the effects of Allium sativum oil and formocresol on the pulp tissue of the pulpotomized teeth. Materials and Methods: Twenty children were selected for this study. All children had a pair of non-vital primary molars. A sterile paper point was dipped in the root canals prior to the mortal pulpotomy. These paper points were collected in transfer media and immediately transported to the microbiological lab to be investigated microbiologically (for Streptococcus mutans and Lactobacillus acidophilus). Then the procedure of mortal pulpotomy was performed. After 2 weeks, the cotton pellets were removed and sterile paper points were dipped in the root canals for microbiological examination. Then comparison between the count of bacteria before and after treatment was conducted. Statistical analysis was performed using independent t-test and paired t-test at the significance level of α = 0.05. Results: After application of both medicaments, there was a marked decrease in S. mutans and L. acidophilus counts. The difference between the mean of log values of the count before and after the application was highly significant for both medicaments (P formocresol on the bacteria of the infected root canals.

    Eleven samples (parchment and paper) from different medieval manuscripts belonging to the cultural heritage of the University of Seville have been radiocarbon dated on the 1 MV AMS facility at the CNA in Seville (Spain). The objective of this study is double. First of all, these are the first real 'unknown' samples treated in the radiocarbon laboratory and dated on our AMS facility, SARA (Spanish Accelerator for Radionuclide Analysis). Besides, some useful information about the manuscripts can be obtained, either to corroborate the dates, or in some cases, to decide between possible dates. As expected, a general agreement is found between radiocarbon results and palaeographical data. Nevertheless, some interesting facts have been learned through this study. We present in this paper the procedure to prepare the samples and the ages obtained with a brief discussion of the results.

  11. Spontaneous generation in medieval Jewish philosophy and theology.

    2012-01-01

    The concept of life forms emerging from inanimate matter--spontaneous generation--was widely accepted until the nineteenth century. Several medieval Jewish scholars acknowledged this scientific theory in their philosophical and religious contemplations. Quite interestingly, it served to reinforce diverse, or even opposite, theological conclusions. One approach excluded spontaneously-generated living beings form the biblical account of creation or the story of the Deluge. Underlying this view is an understanding that organisms that generate spontaneously evolve continuously in nature and, therefore, do not require divine intervention in their formation or survival during disastrous events. This naturalistic position reduces the miraculous dimension of reality. Others were of the opinion that spontaneous generation is one of the extraordinary marvels exhibited in this world and, accordingly, this interpretation served to accentuate the divine aspect of nature. References to spontaneous generation also appear in legal writings, influencing practical applications such as dietary laws and actions forbidden on the Sabbath.

    2007-02-23

    The conventional view holds that girih (geometric star-and-polygon, or strapwork) patterns in medieval Islamic architecture were conceived by their designers as a network of zigzagging lines, where the lines were drafted directly with a straightedge and a compass. We show that by 1200 C.E. a conceptual breakthrough occurred in which girih patterns were reconceived as tessellations of a special set of equilateral polygons ("girih tiles") decorated with lines. These tiles enabled the creation of increasingly complex periodic girih patterns, and by the 15th century, the tessellation approach was combined with self-similar transformations to construct nearly perfect quasi-crystalline Penrose patterns, five centuries before their discovery in the West.

    2015-01-01

    Full Text Available The aim of this study is to evidence diverse materials and processes used by artisans (and alchemists required to synthesize a visually viable replacement for gold. The emphasis of the research is upon the production of mosaic gold or porporina, a pigment that has survived into modern times, which was used as ink and as paint. Base metals, mostly tin, but also alloys were used both into foils coated with glazes and varnishes and as pigment. The research focuses upon recipes documented in treatises dating from Antiquity to the late Medieval period (ca. 1500 and an attempt is made to answer two questions. In the first place, why was there a need for a surrogate? Secondly, why are there so few tangible examples detected on surviving artifacts? In conclusion, an argument is offered pointing out that, although much can be learned by scientific examination of artifacts, textual analysis is equally important and necessary to unravel mysteries of ancient technologies

  14. Orgin of Slag from Early Medieval Age Furnaces in Nitra

    2005-01-01

    Full Text Available Two types of archaeological artefacts from remains of Early Medieval Age furnaces excavated in Nitra are analysed. They are supposed to originate from slag of glass and iron production. Employing Mossbauer spectrometry, iron crystallographic sites are identified and compared. In all samples, Fe2+ and Fe3+ structural positions were revealed. Some of the archeological artefacts including those that were supposed to originate from glass production show a presence of metallic iron and/or magnetic oxides. Based on the results of Mossbauer effect measurements performed at room temperature as well as 77 K (liquid nitrogen temperature analytical evidence is provided that the iron sites identified are not as those usually encountered in glasses. Consequently, a conclusion is proposed that neither of the investigated furnaces was used for glass production.

  15. Thermodynamic model of natural, medieval and nuclear waste glass durability

    A thermodynamic model of glass durability based on hydration of structural units has been applied to natural glass, medieval window glasses, and glasses containing nuclear waste. The relative durability predicted from the calculated thermodynamics correlates directly with the experimentally observed release of structural silicon in the leaching solution in short-term laboratory tests. By choosing natural glasses and ancient glasses whose long-term performance is known, and which bracket the durability of waste glasses, the long-term stability of nuclear waste glasses can be interpolated among these materials. The current Savannah River defense waste glass formulation is as durable as natural basalt from the Hanford Reservation (10 6 years old). The thermodynamic hydration energy is shown to be related to the bond energetics of the glass. 69 references, 2 figures, 1 table

    Full Text Available Apresentaremos neste ensaio três temas para a reflexão: em primeiro lugar, discutiremos a hipótese sobre o caráter eminentemente religioso da ideologia na cristandade medieval. Em seguida, ressaltaremos o papel da "reforma gregoriana" no século XI para a reestruturação desta nova cristandade; por último analisaremos a reação particular que os "reformadores gregorianos" criaram com a temporalidade enquanto categoria antropológica. Cremos que entre o mito e a utopia, os "reformadores gregorianos" tentaram criar, por vezes sem muito êxito, uma fronteira entre uma escatologia oficial e uma escatologia apocalíptica e/ou milenarista, com o designio sobretudo de fazer prevalecer a ordem na sociedade/cristandade.

    2010-02-01

    In the year 2000, an exceptional mural was discovered at a fountain in Massa Marittima, Italy. It depicts a tree with phalluses, which are distributed across all the branches, are disproportionately large and in an aroused state, and include a scrotum. Other examples were identified by systematic literature research. Several other depictions of a phallus tree from the medieval and Renaissance periods exist, for example in manuscripts, as wood carvings, on pilgrimage badges, or frescoes, and were retrieved in Germany, Italy, Belgium, the Netherlands, Turkey, and France. The phallus tree was a well-known phenomenon in Western Europe during the late Middle Ages and the beginning of the Renaissance, and mostly find their roots in the link between infertility and impotence on the one hand, and sorcery and witchcraft on the other.

  1. The Relations between Astronomy and Music in Medieval Armenia

    Vardumyan, Arpi

    2015-07-01

    In Middle Ages Astronomy and Music were included in the four sciences, together with Mathematics and Geometry. From ancient times philosophers thought that harmony lies in the basis of world creation. The Earth was in the centre of the Universe, and the seven planets went around it, the Sun and the Moon in their number. Harmony was also in the basis of music, with seven sounds due to seven planets. It was considered that owing to harmonic rotation cosmic universal music appears, and it is not attainable for human ear as it is used to it. Medieval connoisseurs of music therapy believed that for healing a person his astrological data must first be cleared out, in order to define in which musical mode should sound the melody in order to treat him/her. Comparing music with astrology they considered easier to practise the first one because the celestial luminaries are much higher and farther from people.

    To evaluate the effect of prior application of several intracanal medicaments on the push-out bond strength of ProRoot MTA and Biodentine. Sixty freshly extracted maxillary anterior teeth were sectioned below the cementoenamel junction, and the root canals instrumented using rotary files. Thereafter, a parallel post drill was used to obtain a standardized root canal dimension. The roots were randomly assigned into one of the following groups with respect to the intracanal medicament applied: group 1: calcium hydroxide (CH) powder (Merck, Darmstadt, Germany) mixed with distilled water; group 2: a mixture of metronidazole, ciprofloxacin and minocycline (triple antibiotic paste); group 3: a combination of amoxicillin and clavulanic acid (Augmentin; Champs Pharmacy, San Antonio, TX, USA); group 4: an antibiotic-corticoid compound paste (Ledermix; Riemser, Greifswald, Germany); and group 5: no medicament (control). Following removal of medicaments with instrumentation and irrigation, the roots were cut into 1-mm-thick parallel transverse sections in a coronal-to-apical direction (5 slices/tooth). Thereafter, the specimens were divided into two subgroups according to the calcium silicate cement applied (n = 30/group): (i) ProRoot MTA (Dentsply Tulsa Dental, Tulsa, OK, USA) and (ii) Biodentine (Septodont, Saint-Maur-des-Fosses, France). A push-out test was performed, and the data were analysed statistically using two-way anova and Tukey's post hoc test. Regardless of the type of intracanal medicament used, Biodentine had significantly higher bond strength than MTA (P Biodentine groups, pairwise comparisons between other medicaments showed similar debonding values (P > 0.05). Biodentine had a higher bond strength to root canal dentine than ProRoot MTA. Prior CH in distilled water intracanal placement increased the dislodgment resistance of both calcium silicate cements. © 2015 International Endodontic Journal. Published by John Wiley & Sons Ltd.

    A multiple dating study, involving a collaboration between specialists of dating techniques (thermoluminescence (TL) and radiocarbon), historians of art and archaeologists, has been carried out on several early medieval buildings from western France. The early medieval period is not well known especially in France where there is a lack of visible evidence that identifies pre-Romanesque architecture. The majority of buildings to have survived from this period are religious ones, considered important enough to be made of strong, non-perishable material such as stone or brick, as for example the churches of Notre-Dame-sous- Terre in the Mont-Saint-Michel or St Martin in Angers. Due to their significance in architectural history, it is imperative to position them accurately in the chronology of the history of art. Bricks are often used to build up round-headed arches or to reinforce the frame of a wall with bonding courses in those churches. TL dating and archeomagnetic analysis were performed on cores drilled within bricks while radiocarbon dating were undertaken on coals found within mortars. In order to increase the number of data during the early Middle Ages, archeointensity determinations using the classical Thellier technique with anisotropy of thermal remanence and cooling rate corrections were performed. Archaeomagnetic directions were used to recognize the firing position of bricsk during manufacture. Reliable and precise ages were obtained on the church Notre-Dame-sous-Terre; they indicate two phases of building in 950±50AD and 990±50AD. Mean archeointensities obtained on 17 (21) samples from the first (second) phases appears very closed 69.1±1.2 and 68.3±1.6 microTesla. Ages and archeomagnetic results obtained on 4 other sites will be presented and compared to the available data in western Europe.

  4. Sex differentials in caries frequencies in Medieval London.

    Tooth decay is one of the most common oral infections observed in skeletal assemblages. Sex differentials in caries frequency are commonly examined, with most studies finding that females tend to have a higher frequency of carious lesions (caries) compared to males. Less research has examined differences in caries between males and females with respect to age in past populations. Findings from living populations indicate that caries frequencies are higher in females, at least in part, because of the effects of estrogen and pregnancy. We are interested in the interaction of age, sex, and caries in medieval London, during a period of repeated famines, which might have exacerbated underlying biological causes of caries sex differentials. We examined caries in adults from two medieval London cemeteries dating to c. 1120-1539 AD: St. Mary Spital (n=291) and St. Mary Graces (n=80) to test the hypothesis that males and females have different caries frequencies irrespective of age. The association between maxillary molar caries and sex was tested using hierarchical log-linear analysis to control for the effects of age on caries frequencies. The results indicate a higher frequency of maxillary molar caries in females (P<0.00), and that the age distribution of caries differs between the sexes (P=0.01), with a consistent increase in frequency with age for females until late adulthood, but not males. The difference in caries frequencies is not explained by differences in the age distributions of the sexes. Differences in the age patterns of caries for males and females could be the result of biological factors that present during reproductive age, differences in diet, or differential access to resources during famine.

    With the aim to get a better picture of dental health, diet and nutrition in early medieval Ireland a population-based study focusing on several attributes of oral health in adult individuals was conducted. The study focused on possible differences between sexes and age groups in terms of frequency and distribution of studied pathologies in order to determine whether these differences result from different diets, cultural practices or are age-related. Permanent dentitions belonging to adult individuals from five Irish early medieval sites were examined for the evidence of caries, ante-mortem tooth loss, abscesses, calculus, alveolar bone resorption and tooth wear. All pathologies were analysed and presented by teeth and alveoli. A total of 3233 teeth and 3649 alveoli belonging to 167 individuals (85 males and 82 females) were included into the analysis. Males exhibited significantly higher prevalence of abscesses, heavy wear and alveolar bone resorption, while females exhibited significantly higher prevalence of calculus. All studied dento-alveolar pathologies showed a strong correlation with advanced age, except calculus in females. Additionally, dental wear associated with habitual activities was observed in two females. The results of the present study confirm the data gained by written sources and stable isotopes analyses suggesting the diet of the early Irish was rich in carbohydrates with only occasional use of meat. Furthermore, significant differences between the sexes in terms of recorded pathologies strongly suggest different nutritional patterns with females consuming foods mostly based on carbohydrates in comparison to males. The observed sex-differences might also occur due to differences between male and female sex such as reproductive biology and pregnancy, a somewhat different age distributions, but also as a result of different cultural practices between the sexes.

    Full Text Available Artefacts produced or treated at high temperatures provide information about manufacturing techniques. Well preserved ceramic objects are therefore excellent chronological markers as well as general markers of society development. In order to determine provenance of pottery fragments, archaeologists classify samples according to their physical characteristics, decoration and aesthetic style. However, a more objective multidisciplinary approach, based on undoubted results, is necessary to complete this study. In this work we have investigated 27 samples of medieval ceramics from excavation site Novo Brdo, using X-ray fluorescence (XRF, FTIR spectroscopy and X-ray powder diffraction (XRPD. Novo Brdo was large and rich mining and trading center of Serbia in XIV and XV century. A large number of ceramic samples found during the systematic excavation of this archaeological site allow good choice of samples for both destructive and nondestructive analysis. Combining results obtained by different experimental techniques, i.e. by FT-IR spectroscopy, after deconvolution of the spectra, and XRPD analysis, we have determined mineralogical composition and technology of production of investigated pottery. Estimated temperature of firing ranged from 800 to 900 °C, which is in agreement with the presence of high-temperature minerals like gehlenite and anorthite. Firing was preformed in the oxidation atmosphere since hematite, which is formed only in oxidation atmosphere, is detected in all investigated samples. Cross sections showed presence of defects and inhomogeneity of investigated ceramic, which indicates fast and incomplete firing procedure. All these findings indicate that investigated pottery was produced in the domestic workshops. The obtained results will be used to build up the National database for medieval ceramics as well as the database for the Balkan region.

  7. Pliny’s Naturalis Historia and Medieval Animal Iconography

    Studying Pliny’s influence on animal iconography is rendered additionally difficult because the methods of transferring content from literary tradition into an artistic medium have been insufficiently explored. The most tangible and recognizable is the role of bestiaries; in numerous examples of late Romanesque and Gothic sculptures it is possible to prove the direct influence of animal illuminations and descriptions in bestiaries, in which the method of depiction expresses the awareness of the symbolic value of the animal, which is transferred from the bestiaries into architectural sculpture and other fine arts media. A special role in studying the transfer of allegoric content from bestiaries into medieval animal iconography is played by the written records of medieval artists, which have been rarely preserved, and especially by “pattern books” (Musterbücher, which on the one hand sculptors and painters used as a direct template and, on the other, undoubtedly express the author’s knowledge of bestiaries. Thus, the animal drawings from the famous Sketchbook of Villard de Honnecourt indicate that the author was familiar with contemporary bestiaries and found inspiration in them; however, the relations between the drawings – juxtaposition of positively and negatively valued animals – indicates that he also took their symbolic value into account. Villard’s Sketchbook reveals an additional interesting detail: his annotation to the drawing of a porcupine reveals the influence of Pliny’s Naturalis Historia on the formation of the symbolic meaning of animals because Villard explicitly mentions features of the porcupine that were first mentioned by Pliny the Elder.

    Full Text Available When it comes to writing about the history of punishment, it is always linked with critically re-thinking and better understanding of the contemporary system of punishment, as a result of its long historical development. In such a way, „contemporary criminal law cannot be seen as a result of an effort made by a certain nation or in a certain epoch“. „Permanently faced with social changes, in its long historical development, criminal law has been modifying its fundamental principles and categories, by building new institutes and instruments, in order to become less cruel and more human, but not less efficient than in earlier stages of its development, characterized by rudeness, cruelty and exemplarity of its sanctions. Although it is not easy to answer the question, if there is the measure, in which social understanding of punishment and its purpose, determines the civilizational level in the society, there is no doubt about the fact that civilizational and legal point of view towards punishment derives from a waste range of factors: general, cultural, sociological, psychological, religious, political and other factors that should be taken altogether in their historical dimension. The genesis of criminal law is linked with the moment of establishing the public authorities and the state. According to different criteria, it is possible to introduce different periodization of criminal law. When it comes to the historical criterion, there can be made a historical division into periods of ancient, medieval, modern and contemporary criminal law (punishment, which periods should not be taken as absolutely inseparable. The point of this paper is to present a review and development of punishing active bribery in the Croatian medieval and modern law.

    Full Text Available Although early medieval Serbian ceramic is well described by the archeologists and historians, knowledge of the Balkan ceramic production is still limited. Archaeometric study of ceramics provenance, technology of preparation and used pigments as well as influence of neighboring countries and specific characteristics of different workshops has never been performed so far. The detailed knowledge of the micro-chemical and micro-structural nature of an archaeological artifact is critical in finding solutions to problems of restoration, conservation, dating and authentication in the art world. In this work we present results of systematic investigation of pottery shards from archeological site Ras. The term Ras, which signifies both the fortress and the region encompassing the upper course of Raška River, used to be the center of the medieval Serbian state. Both the ceramic body and the polychromatic glaze of the artifacts were studied by a multianalitical approach combining optical microscopy (OM, FT-IR spectroscopy and X-ray fluorescence (XRF. Mineralogical composition of pottery shards has been determined combining results obtained by FT-IR spectroscopy, after deconvolution of the spectra, and XRPD analysis. Firing temperature has been estimated based on the mineralogical composition and positions of Si-O stretching (-1000 cm-1 and banding (-460 cm-1 vibrations. Investigated samples have been classified into two groups based on the mineralogical composition, cross sections and firing temperature. Larger group consists of samples of fine-grained, homogeneous ceramics with firing temperatures bellow 800 °C which indicates imported products. Second, smaller group consists of inhomogeneous ceramics with firing temperatures between 850 and 900 °C produced in the domestic workshops. The obtained results will be used to build up a national database for the compositions of bodies, glazes and pigments.

    Since centuries, natural compounds from plants, animals and microorganisms were used in medicinal traditions to treat various diseases without a solid scientific basis. Recent studies have shown that plants that were used or are still used in the medieval European medicine are able to provide relieve for many diseases including cancer. Here we summarize impact and effect of selected purified active natural compounds from plants used in European medieval medicinal traditions on cancer hallmarks and enabling characteristics identified by Hanahan and Weinberg. The aim of this commentary is to discuss the pharmacological effect of pure compounds originally discovered in plants with therapeutic medieval use. Whereas many reviews deal with Ayurvedic traditions and traditional Chinese medicine, to our knowledge, the molecular basis of European medieval medicinal approaches are much less documented.

    Full Text Available ResumenEn este ensayo se va a tratar sobre arquitectura a partir de la definición de forma como “estructura esencial e interna, como construcción del espacio y de la materia”. Para ello, podemos establecer, como punto de partida, que el proceso de la arquitectura va de la energía, las fuerzas y la materia hacia la forma. Por tanto, teorizar sobre la forma en arquitectura nos lleva a reflexionar sobre tres fenómenos previos a su configuración: la energía, las fuerzas y la materia. Para seguir estos procesos físicos es útil remitirse al pensamiento postestructuralista de Gilles Deleuze y Félix Guattari, especialmente a su texto Mil Mesetas. Capitalismo y esquizofrenia (1980 y a conceptos como “rizoma” y “agenciamiento” y, sobre todo, utilizar la herramienta interpretativa y creativa del “diagrama”.Palabras claveenergía, fuerza, materia, forma, Deleuze, GuattariAbstractThis essay will deal on architecture from the defi nition of form as "critical and internal structure  as construction of space and matter." For that, we can establish, as a starting point, that the process of architecture goes from energy, forces and matter to form. Thus, theorizing about form in architecture leads us to refl ect on three prior phenomena to its confi guration: energy, forces and matter. To follow these physical processes is useful to refer the poststructuralist thought´s Gilles Deleuze and Felix Guattari, especially his text A Thousand Plateaus.

  6. Two medieval doctors: Gilbertus Anglicus (c1180-c1250) and John of Gaddesden (1280-1361).

    Biographies of medieval English doctors are uncommon and fragmentary. The two best-known English medieval physicians were Gilbertus Anglicus and John of Gaddesden. This paper brings together the known details of their lives, compiled from extant biographies and from internal references in their texts. The primary records of their writings exist in handwritten texts and thereafter in incunabula from the time of the invention of printing in 1476. The record of the lives of these two medieval physicians can be expanded, as here, by the general perspective of the life and times in which they lived. Gilbertus Anglicus, an often-quoted physician-teacher at Montpellier, wrote a seven-folio Compendium medicinae in 1271. He described pioneering procedures used later in the emergent disciplines of anaesthetics, cosmetic medicine and travel medicine. Gilbertus' texts, used extensively in European medical schools, passed in handwritten copies from student to student and eventually were printed in 1510. John of Gaddesden, an Oxford graduate in Arts, Medicine and Theology, wrote Rosa Anglica, published circa 1314. Its detailed text is an exemplar of the mixture of received Hippocratic and Galenic lore compounded by medieval astronomy and religious injunction, which mixture was the essence of medieval medicine. The writings of both these medieval English physicians formed part of the core curriculum that underpinned the practice of medicine for the next 400 years.

    Microbial biofilm is defined as a sessile multicellular microbial community characterized by cells that are firmly attached to a surface and enmeshed in a self-produced matrix of extracellular polymeric substances. Biofilms play a very important role in pulp and periradicular pathosis. The aim of this article was to review the role of endodontic biofilms and the effects of root canal irrigants, medicaments as well as lasers on biofilms A Medline search was performed on the English articles published from 1982 to 2013 and was limited to papers published in English. The searched keywords were “Biofilms AND endodontics”, “Biofilms AND sodium hypochlorite”, "Biofilms AND chlorhexidine", "Biofilms AND MTAD", "Biofilms AND calcium hydroxide", “Biofilms AND ozone”, “Biofilms AND lasers” and "Biofilms AND nanoparticles". The reference list of each article was manually searched to find other suitable sources of information. PMID:24688576

    Finger citron [Citrus medica L. var. Sarcodactylis Hort, Rutaceae] (FC) fruits, widely cultivated in Japan, the southern provinces of China and Taiwan, are commonly used as functional vegetables and preserved as sweetmeats. Previously we identified the major compounds in essential oils (% in EO) of FC fruits to be d-limonene (51.24), gamma-terpenene (33.71), alpha-pinene (3.40), and beta-pinene (2.88). Documented evidence on its insulin secretion characteristics is still lacking. In parallel to compositional analysis, we performed in vivo the safety, hypoglycemic, and antidiabetic tests in Sprague-Dawley-SPF rats and Wistar DIO rats respectively. By kinetic analysis on the hypoglycemic patterns of the intraperitoneal glucose tolerance (IPGTT) and the insulin-glucose tolerance tests (IGTT), its insulin secretagogue effect was confirmed. In conclusion, FC fruits that concomitantly possess insulin secretagogue and slimming effects would be very beneficial to type 2 diabetes mellitus patients.

Materials and Methods: A total of 125 extracted premolars were equally divided into five groups. Group 1: Control, Group 2: Fluor-Protector, Group 3: TM Plus, Group 4: Enafix, and Group 5: Amflor. Apical third of the root of bracketed teeth was sectioned off to secure teeth to the inner surface of plastic lids of 20 ml specimen jars with adhesive wax with crown immersed in Ten Cates solution. Group 1 received no further treatment; Group 2 received a single application of Flour-Protector, and Group 3, Group 4, and Group 5 received 0.5 ml applications of TM Plus, Enafix, and Amflor, respectively. Specimens were then immersed in jars containing Ten Cates solution (pH 4.3. TM Plus, Enafix, and Amflor were reapplied over Group 3, Group 4, and Group 5, every 4 hours; Group 2 received a single application of Fluor-Protector during the period of 96 h. Longitudinal sections were done; linear demineralization depth was registered using a polarized light microscope. Results: Mean enamel demineralization of groups was measured in micrometers: Control was highest, i.e., 182.98 ± 7.10, followed by Enafix i.e., 167 ± 6.00; Amflor, i.e., 165 ± 4.94; Fluor-Protector, i.e., 159.72 ± 4.62; and TM Plus, i.e.,151 ± 6.21. On comparison of groups by analysis of variance, a P = 0.004 was found. On comparison by Tukey's test, P = 0.04 between Group 1 versus 2 and P = 0.002 between Group 1 versus 3 were found, and the rest was nonsignificant. Conclusion: TM Plus was found the best among different medicaments, followed by Fluor-Protector, Amflor, and finally Enafix.

  11. Studies of beneficial interactions between active medicaments and excipients in pharmaceutical formulations.

    A review of "up to date" research findings leading to new concepts of the pharmaceutical formulations and their interactions has been presented. The rational approaches to the excipients choice as well as to their interactions with medicaments have been shown as a basis for modern modelling of pharmaceutical formulations. The importance of complexation, hydrogen bonding, ion-dipole, dipole-dipole and van der Waals attractions as the tools which can modify the physicochemical, pharmacological or pharmacokinetical behaviour of the medicaments has been emphasised. In vivo studies (carried out in healthy human subjects-volunteers, in beagle dogs, in rats etc.) and in vitro studies (on excised human skin, hairless mouse skin etc.) as well as studies of chemical stability and bioavailability serve also as a proof of these interactions. Therefore, excipients are important components of pharmaceutical formulations and they can take an active part in the improvement of the characteristics of formulations (but they may also reduce the effectiveness of some preparations). In this context, the so called active and inactive ingredients in pharmaceutical formulations are inexact, old and "out-of date". Their further use is only conventional. In conclusion, among the various modern techniques applied the combination of infrared spectroscopy and X-ray diffraction has been estimated as the most successful in proving the interactions between drugs and excipients. Finally, pharmaceutical formulations and their interactions have constituted a diverse and rapidly expanding field of Pharmacy (Pharmaceutical Technology, Pharmaceutical Industry and Pharmaceutical Sciences) which covers a wide range of numerical topics within an unified framework.

    2013-12-01

    Full Text Available La disciplina de las aguas se encuentra estructurada jurídicamente, sólo en base a dos derechos: el de propiedad y el de aprovechamiento. La caracterización que posee el agua como cosa, impide que puedan ejercerse otros derechos sobre ella.El punto de partida para explicar este fenómeno, radica en que el agua responde a dos hechos técnicos que ofician como fuente material o factor de calificación jurídica: el principio de territorialidad y la unidad del ciclo hidrológico. Estos dan motivo a su comportamiento universal y en ellos se asienta su disciplina, más allá de la regulación particular que cada derecho positivo quiera desarrollar, imponiendo una política en la materia.  En síntesis, el agua es un bien cuyas particularidades determinan que en definitiva, el derecho de propiedad sea desplazado en su trascendencia patrimonial por otro derecho que ocupa su lugar en jerarquía e individualidad: el derecho de aprovechamiento. Sin embargo y a pesar de los sólidos fundamentos que lo sustentan, la identidad de este derecho parece todavía opacada por los reflejos de una propiedad, que en materia de aguas, es inoperante.

  17. Seasonal climate variability in Medieval Europe (1000 to 1499)

    Pfister, C.

    2009-04-01

    In his fundamental work on medieval climate Alexandre (1987) highlighted the significance of dealing with contemporary sources. Recently, long series of temperature indices for "summer" and "winter" were set up by Shabalova and van Engelen (2003) for the Low Countries, but the time resolution is not strictly seasonal. This paper worked out within the EU 6th Framework Project "Millennium" draws on critically reviewed documentary evidence from a spatially extensive area of Western and Central Europe (basically England, France, BENELUX, Western Germany, Switzerland, Austria, Poland, Hungary and todays Czech Republic. The narrative evidence is complemented with dendro-climatic series from the Alps (Büntgen et al. 2006). Each "climate observation" is georeferenced which allows producing spatial displays of the data for selected spaces and time-frames. The spatial distribution of the information charts can be used as a tool for the climatological verification of the underlying data. Reconstructions for winter (DJF) and summer (JJA) are presented in the form of time series and charts. Cold winters were frequent from 1205 to 1235 i.e. in the "Medieval Warm Period" and in the Little Ice Age (1306-1330; 1390-1470). Dry and warm summers prevailed in Western and Central Europe in the first half of the 13th century. During the Little Ice Age cold-wet summers (triggered by volcanic explosions in the tropics) were more frequent, though summer climate remained highly variable. Results are discussed with regard to the "Greenhouse Debate" and the relationship to glacier fluctuations in the Alps is explored.

    The aim was to determine the effect of four different intracanal medicaments on the apical seal of the root canal system in vitro. Fifty freshly extracted intact human permanent maxillary central incisors were collected, stored and disinfected. The root canals were prepared to a master apical size of number 50 using step back technique. Depending upon the intracanal medicament used, the teeth were divided randomly into five groups of 10 teeth each including one control group and four experimental groups. Group A: No intracanal medicament. Group B: Calcium hydroxide powder mixed with distilled water. Group C: Calcium hydroxide gutta percha points (calcium hydroxide points). Group D: 1% chlorhexidine gel (hexigel). Group E: Chlorhexidine gutta percha points (Roeko Activ Points). The medication was left in canals for 14 days. Following removal of the intracanal medicament, all the groups were obturated with lateral compaction technique. The apical leakage was then evaluated using dye extraction method with the help of a spectrophotometer. RESULTS were statistically analyzed using Kruskal-Wallis and Mann-Whitney U-test, which showed statistically significant difference among the five groups tested. It can be concluded from this study that the control group showed least amount of leakage, whereas the 1% chlorhexidine gel group showed maximum amount of leakage. Apical leakage was observed with all the experimental groups with little variations in between them. Under the parameters of this study, it can be concluded that use of intracanal medicaments during endodontic treatment has a definite impact on the apical seal of the root canal system.

  20. On the distribution of trace element concentrations in multiple bone elements in 10 Danish medieval and post-medieval individuals.

    The differences in trace element concentrations among 19 different bone elements procured from 10 archaeologically derived human skeletons have been investigated. The 10 individuals are dated archaeologically and some by radiocarbon dating to the medieval and post-medieval period, an interval from ca. AD 1150 to ca. AD 1810. This study is relevant for two reasons. First, most archaeometric studies analyze only one bone sample from each individual; so to what degree are the bones in the human body equal in trace element chemistry? Second, differences in turnover time of the bone elements makes the cortical tissues record the trace element concentrations in equilibrium with the blood stream over a longer time earlier in life than the trabecular. Therefore, any differences in trace element concentrations between the bone elements can yield what can be termed a chemical life history of the individual, revealing changes in diet, provenance, or medication throughout life. Thorough decontamination and strict exclusion of non-viable data has secured a dataset of high quality. The measurements were carried out using Inductively Coupled Plasma Mass Spectrometry (for Fe, Mn, Al, Ca, Mg, Na, Ba, Sr, Zn, Pb and As) and Cold Vapor Atomic Absorption Spectroscopy (for Hg) on ca. 20 mg samples. Twelve major and trace elements have been measured on 19 bone elements from 10 different individuals interred at five cemeteries widely distributed in medieval and renaissance Denmark. The ranges of the concentrations of elements were: Na (2240-5660 µg g -1 ), Mg (440-2490 µg g -1 ), Al (9-2030 µg g -1 ), Ca (22-36 wt. %), Mn (5-11450 µg g -1 ), Fe (32-41850 µg g -1 ), Zn (69-2610 µg g -1 ), As (0.4-120 µg g -1 ), Sr (101-815 µg g -1 ), Ba (8-880 µg g -1 ), Hg (7-78730 ng g -1 ), and Pb (0.8-426 µg g -1 ). It is found that excess As is mainly of diagenetic origin. The results support that Ba and Sr concentrations are effective provenance or dietary indicators. Migrating

  1. The long-term impact of developmental stress. Evidence from later medieval and post-medieval London (AD1117-1853).

    Episodes of ill-health in childhood can predispose affected individuals to further periods of illness and early adult mortality. This study uses nonspecific indicators of stress to examine how growth disruptions during infancy/early childhood, and late childhood/early adolescence affected adult longevity in later medieval and post-medieval London. Hazards analysis was used to evaluate the effect of linear enamel hypoplasia (LEH) and the size of the anteroposterior (AP) and transverse (TR) diameters of the vertebral neural canal (VNC) on adult age-at-death. This was applied to skeletal samples from later medieval (n = 461) and post-medieval (n = 480) London. Growth disruptions during infancy/early childhood (LEH and AP VNC diameters) were not associated with longevity, or with impaired growth at later stages of development (TR VNC diameters). Growth disruptions during late childhood/early adolescence (TR VNC diameters) were associated with a significantly increased risk of adult mortality. Macroscopic hypoplasia represent short periods of stress during infancy/early childhood which did not disrupt future investments in growth or cause long-term damage to health. Small TR diameters represent chronic stress during late childhood/early adolescence which resulted in greater susceptibility to infections and increased risk of mortality. These interactions were influenced by sex and socioeconomic status, suggesting that socioeconomic circumstances in both childhood and adult life could influence exposure and resistance to stressors. © 2015 Wiley Periodicals, Inc.

    Museums are buildings of particular significance due to their function and their status. At the same time they are buildings in which the principles of energy conservation are rarely applied, sometimes without reason. It has been decided by the Hellenic Ministry of Culture to convert a medieval tower, built in the year 1344 as a fortress with 0.8-1.5 m thick walls and almost no windows, into a museum. The present paper discusses the difficulties that arise in the attempt to balance between the indoor climate conditions necessary to protect the exhibits and to provide comfortable conditions to the visitors, whilst respecting the aesthetics and the historical significance of the building. Furthermore, one needs to consider the difficult but necessary task of assessing factors such as the building's shell's thermal conductivity and capacity, the ventilation necessary as well as the indoor air movement, in order to determine the cooling loads. Finally, the challenge lies in designing and dimensioning an effective and efficient HVAC system, which should be as discrete as possible. The present paper aims to present the results of the study, to discuss the expected energy behaviour of the building and to comment on the options for introducing energy conservation techniques.

    A multi proxy approach was applied in the reconstruction of the architecture of Medieval horse stable architecture, the maintenance practices associated with that structure as well as horse alimentation at the beginning of 13th century in Central Europe. Finally, an interpretation of the local vegetation structure along Morava River, Czech Republic is presented. The investigated stable experienced two construction phases. The infill was well preserved and its composition reflects maintenance practices. The uppermost part of the infill was composed of fresh stabling, which accumulated within a few months at the end of summer. Horses from different backgrounds were kept in the stable and this is reflected in the results of isotope analyses. Horses were fed meadow grasses as well as woody vegetation, millet, oat, and less commonly hemp, wheat and rye. Three possible explanations of stable usage are suggested. The stable was probably used on a temporary basis for horses of workers employed at the castle, courier horses and horses used in battle.

    Full Text Available The various regions of the Indian subcontinent came into contact with the Islamic cultural tradition in the seventh century CE. Indian scholars were able to leave a mark on the world of Islamic scholarship especially in the fields of ḥadīth and other connected disciplines, significantly underlining their recognition for contributions in the Islamic East. An attempt has been made to analyse and to understand the processes of transmission of knowledge through formal and informal means, including the transfer of accumulated experience to the next generation and even the passing of “intuitive knowledge” to the seeker of knowledge. It has been argued that the level of Indian scholarship in certain disciplines was at par with the level of scholarship in the Islamic East. It has also been examined that during the medieval period Sanskrit based studies flourished at important Hindu pilgrimage centres such as Benaras, often described by European travellers as the Athens of India. The Royal and private libraries functioned with firm footings. Finally, it is shown that education and transmission of knowledge was organized in a manner that owes much to the best of Greco-Arab tradition.

    Articular eminence inclination (AEI) of the temporomandibular joint leads the mandible in its movements. Therefore, the aim of the present study was to determine AEI values in medieval (MP) and recent (RP) Croatian population. The study was carried out on two groups of specimens: first group with 30 MP human dry skulls, while the other, serving as control group consisted of 137 dry skulls. The AEI was measured on lateral digital skull images as the angle between the best fi t line drawn along the posterior wall of the articular eminence and the Frankfurt horizontal plane. No statistically significant (p>0.05) differences between the left and right side AEI were found between MP skulls and RP skulls. The mean value of MP AEI was 45.5˚, with a range of 20.9˚-64˚. The mean RP AEI value was steeper (61.99˚), with a range of 30˚-94˚. Difference between the mean MP and RP AEI values was statistically significant (pmedieval time, and consequently different masticatory loads and forces.

    We aimed to acquaint the reader with a medieval physician, Amirdovlat Amasiatsi, who lived and practiced in the 15th century Anatolia. Amirdovlat wrote several books on medicine mainly focusing on phytotherapy and pharmacology using medicinal plants, animal-derived products and minerals. All his works were written in Middle Armenian, spoken Armenian language of the time. In his writings, Amirdovlat described unique recipes that represent a portrayal of medical knowledge and practice at the time in Anatolia where he lived and worked. He discussed the physical and therapeutic properties as well as geographic distributions of various plants and minerals, using different languages, mainly Turkish, Greek, Arabic, French and Persian. Amirdovlat's works not only enhanced our understanding of Armenian medical practices but also provided great deal of information on those of Ancient Greco-Roman as well as Islamic world, demonstrating close relationship of Armenian medicine with Greco-Roman and Islamic medicine. Amirdovlat accomplished this by amalgamating the past and contemporary practices of his time. In this regard, Amirdovlat's works, in particular "Useless for the Ignorant", are very unique playing a significant role in preserving traditions and heritage of different cultures.

  12. Madness and care in the community: a medieval perspective.

    Science.gov (United States)

    Roffe, D; Roffe, C

    Care in the community for insane people today is more a matter of expert provision than communal support. In consequence, although they are no longer confined to hospital, mentally ill people largely remain marginalised in a society that does not have the resources, nor often the inclination, to take responsibility for their care. The experience of insane people in medieval England seems to have been of a different order, as shown by a particularly well documented case dating from 1383. From the late 13th century congenital idiots were protected by law. Care of lunatics, by contrast, was primarily the responsibility of the family. However, where the family could not or was unwilling to provide, provision was made by the crown. Through the instrument of the inquisition, the diagnosis and social circumstances of each case were determined by commissioners in consultation with a local jury and all interested parties, including the subject himself or herself. The best interests of the subject remained a prime concern, and the settlement that was ordained was tried and enforced in law. The process was confined to those with real or personal estate, but it encompassed poor as well as rich and proved, through the close identity of the local community with the process, to be a sophisticated and effective mechanism for maintaining and sustaining insane people. Unlike today, care in the community was a communal activity that ensured a truly public provision for those who could not look after themselves.

  13. The Name Day as a Part of Medieval Historiographical Narrative

    Directory of Open Access Journals (Sweden)

    Anna F. Litvina

    2015-08-01

    Full Text Available The article investigates the ways in which the celebration of the name day (imeniny of Russian princes or their entourages was presented in the Russian chronicles. The custom of celebrating the name day was firmly rooted in the Russian princely environment. For a chronicle narrative, the very rootedness of this custom and the number of its associated actions plays an important role—it is this rootedness that makes stories told in the chronicles quite opaque to the modern reader. A prince’s Christian name and the day of his patron saint were considered to be important background knowledge for the audience of the medieval compiler. There were, apparently, clear ideas about appropriate behavior for prince or a person from his environment on his name day or on the eve of this day but, on the other hand, such assumptions explain why this kind of “normal” behavior rarely forms the subject of special reflection in the chronicles. It is not only a description of the celebration itself that might be very informative, whether it be a church service, a ceremonial feast with various relatives, or an exchange of gifts, but also the description of acts and deeds that were undertaken specifically on a prince’s name day. Therefore, particular attention is given here to stories about undue or inappropriate behavior on this special day. The paper deals with the function and nature of such episodes in the broader context of historiographical narrative.

  14. [Meat inspection in the medieval Zähringer towns.].

    Häsler, S

    2010-01-01

    An explanation of medieval practices of meat supply and regulation, using examples drawn from the so-called "Zähringer towns" founded by the Dukes of Zähringen: Bern, Burgdorf, Thun, Murten, Freiburg and Rheinfelden. For the town councils it was important to be able to provide the population with sufficient quantities of good-quality meat at fair prices. After the 14th century the slaughtering of animals had to be carried out in public slaughterhouses. Meat could only be sold publicly, at designated butchers' stalls. Meat and organs were checked on a daily basis by the town's meat inspectors, who verified the names under which products were sold, their price, and hygienic conditions, including the absence of tapeworm larvae. In addition to the publicly-regulated meat trade, town dwellers could also buy meat products at the markets, and could raise their own pigs, sheep and goats to be slaughtered in the back alleys. Permission to raise small livestock at home was a privilege granted by the town council. The sale of meat by non-resident peddlers was officially forbidden, but could not be prevented entirely.

  15. Medieval Round Churches and the Shape of the Earth.

    Haagensen, Erling; Lind, Niels C

    2015-12-01

    There is a unique cluster of four medieval round churches, linked by a simple geometry, on Bornholm Island in the Baltic Sea. Why so many and why so close together? Immediate simple answers are "Just by chance" and "For no reason." Why are the churches round? "Defense." This essay proposes another hypothesis for this unique situation: the churches are astronomical observatories, meant to solve a scientific problem (Is the Earth really spherical?) and a practical problem (How far is it to sail west to the Orient?). The capacity and desire to find answers, together with other practical needs related to astronomy, can better explain these round churches' special architecture. The geometry that connects them fits the ideal pattern with an angular accuracy of 1 minute of a degree. The round churches may be the earliest astronomical observatories in Christian Europe; other hypotheses have been shown to be untenable. Their location provides for a good method to estimate the Earth's extent in the east-west direction, seemingly the earliest such measurements.

    2014-01-01

    This article investigates the roots of the sub-discipline medieval archaeology that emerged in German-speaking universities in the 1950s and 1960s. In the 1930s, research practices crucial for the formation of medieval archaeology, such as the investigation of medieval castles and peasant houses, became more prominent in the humanities, especially in the context of vilkisch research. After the Nazis took power in Germany, they encouraged such research because it built a scientific basis for their nationalist policy. This politically motivated funding did not result in a new discipline, in contrast to research fields such as prehistory and folklore studies. In this article, I propose two explanations for why medieval archaeology did not emerge as an interdisciplinary research field in the 1930s and 1940s, even though the course was set for its development. First, for archaeologists, art historians, and regional medieval historians, research objects such as medieval castles were semantically too indeterminate. Archaeologists would investigate a castle as a building completely destroyed and buried under rubble, while art historians would be interested in its building technique, and regional medieval historians in its written record. Second, disciplines that were important for the creation of medieval archaeology, such as prehistoric archaeology, art history, and regional medieval history, structurally did not allow for the emergence of an interdisciplinary research field in the 1930s. In particular, prehistoric archaeology, which was crucial for the development of medieval archaeology, itself was not fully institutionalized at universities in the 1930s. This institutionalization process prevented the emergence and development of an interdisciplinary research field such as medieval archaeology To demonstrate this argument, I draw on two examples of investigations of castles, one in Nazi Germany and the other in the German-speaking part of Switzerland.

  17. ‘FOR MUSIKE MEUEÞ AFFECCIOUNS’: INTERPRETING HARP PERFORMANCE IN MEDIEVAL ROMANCE

    Directory of Open Access Journals (Sweden)

    Alana Bennett

    2015-12-01

    Full Text Available Performances are focal points in medieval romances with musical protagonists. Whilst these performances may not necessarily be accurate representations of medieval music, such episodes in popular literature are valuable to early music practitioners because they describe the whole context of the performance. These scenes preserve a snapshot of the medieval experience of music: the physicality of the performance, the sounds created and the emotional responses to the music. The hyperbolic tendencies of popular literature are effective at communicating imagined performance contexts because of the use of language that deliberately presents and evokes extremes of emotion, involving the reader or listener in a simulacrum of musical affect. When used alongside surviving musical notation, musical treatises, accounts of performances in historical records, and iconography, these romances are, I argue, a highly valuable and informative source for medieval performance. They reveal to the modern reader how music was perceived and represented in the medieval popular imagination. This paper will examine harp performances in several music-focused romances and I will set alongside these examples my own amateur reconstructions of the performances as described.

  18. Stressing out in medieval Denmark: An investigation of dental enamel defects and age at death in two medieval Danish cemeteries.

    2017-06-01

    The influence of early life stress on later life experiences has become a major focus of research in medicine and more recently in bioarchaeology. Dental enamel, which preserves a record of childhood stress events, represents an important resource for this investigation when paired with the information from adult skeletal remains, such as age at death. The purpose of this research was to use a life history approach to the exploration of sex differences in the relationship between childhood stress and adult longevity by examining accentuated striae of Retzius (AS). A medieval Danish sample (n=70) drawn from the rural cemetery of Sejet and the urban cemetery of Ole Wormsgade was considered for AS and age at death. The results suggest sex differences in survivorship, with more stress being associated with reduced survivorship in males and increased survivorship in females. A consideration of AS formation time also suggests a difference in the impact of developmental timing between males and females. These results are interpreted in terms of differential frailty and selective mortality, drawing in both biomedical and cultural perspectives. Copyright © 2017 The Authors. Published by Elsevier Inc.

    2010-01-01

    Full Text Available On the basis of disclosed and closed records of the Dubrovnik Archive, Turkish census from 1468-1469. and 1475-1477, researches on the ground and relevant literature, we made an attempt to discover how the župa of Vatnica got its name and to define its borders that parted the area of Travunia from the area of Hum. Vatnica had been populated before Slavic people settled the area. Recent history records present Vatnica borders vaguely and imprecisely. Our findings contradict the findings presented in history records that state Travunia borders stretch to Trusina. The župa of Vatnica was placed eastward from the župa of Dabar in Hum land, with the borderline alongside Divin and Kuti village. In the northwest Vatnica bordered župa of Nevesinje alongside Davidovići and Lukavac villages, while the southeast border was reaching župa of Rudine, east from Narat village. Turkish invasion brought in suffering and migrations with local people causing them to leave their homes. Turkish administrative system naturalized itself according to its needs thus changing the old borders. While occupied by Turks, a part of former župa of Vatnica, including Vatnica village, became a part of Turkish nahiya Dabar, but at the same time on the east side of Vatnica village existed nahiya of Vatnica stayed behind with six unpopulated villages, which was supported by the Turkish census. Windy political odds affected the medieval economy of Vatnica. Population pursued agriculture, above all grape growing. They would breed draught cattle for transport and market. Economy of this region was partly influenced by Dubrovnik where the youngster would go to find work and learn trade. Remainders of the past times are stone tombs called 'stećak' as well as the sites of orthodox churches.

  10. An Early Medieval Tradition of Building in Britain

    Directory of Open Access Journals (Sweden)

    Gardiner, Mark

    2012-12-01

    Full Text Available Early medieval houses in Britain were largely constructed of timber. Various approaches have been adopted for interpreting the character of these buildings, since no standing structure survives. These include the study of water-logged timber, the reproduction of methods of working and the reconstruction of buildings, as well as the conventional analysis of the plans of excavations. The problems of identifying the ethnic affiliations of houses in Britain are particularly acute because the structural features which define the building traditions in England and Scotland have rarely been identified. However, it is argued that it is possible to identify a distinctive tradition of building in timber which persists from the fifth to the eleventh or even twelfth century, and is found throughout England and into southern Scotland.En la Gran Bretaña de la alta Edad Media se solían construir las viviendas de madera y por consiguiente no queda ninguna estructura en pie. Así, se han adoptado varios enfoques para interpretar las características de dichas viviendas, como el análisis de la madera saturada de agua, la recreación de la metodología de trabajo y la reconstrucción de edificios, así como los tradicionales análisis de las plantas de las construcciones en las excavaciones. La atribución étnica de las viviendas en Gran Bretaña resulta especialmente difícil porque rara vez se han identificado las tradiciones constructivas de Inglaterra y Escocia. No obstante, se ha argumentado que es posible identificar a una tradición característica de construcción en madera que se mantuvo del siglo V al siglo XI e incluso hasta el siglo XII y que se puede encontrar en toda Inglaterra y en el sur de Escocia.

    The Himalayas and their foreland belong to the world's most earthquake-prone regions. With millions of people at risk from severe ground shaking and associated damages, reliable data on the spatial and temporal occurrence of past major earthquakes is urgently needed to inform seismic risk analysis. Beyond the instrumental record such information has been largely based on historical accounts and trench studies. Written records provide evidence for damages and fatalities, yet are difficult to interpret when derived from the far-field. Trench studies, in turn, offer information on rupture histories, lengths and displacements along faults but involve high chronological uncertainties and fail to record earthquakes that do not rupture the surface. Thus, additional and independent information is required for developing reliable earthquake histories. Here, we present exceptionally well-dated evidence of catastrophic valley infill in the Pokhara Valley, Nepal. Bayesian calibration of radiocarbon dates from peat beds, plant macrofossils, and humic silts in fine-grained tributary sediments yields a robust age distribution that matches the timing of nearby M>8 earthquakes in ~1100, 1255, and 1344 AD. The upstream dip of tributary valley fills and X-ray fluorescence spectrometry of their provenance rule out local sediment sources. Instead, geomorphic and sedimentary evidence is consistent with catastrophic fluvial aggradation and debris flows that had plugged several tributaries with tens of meters of calcareous sediment from the Annapurna Massif >60 km away. The landscape-changing consequences of past large Himalayan earthquakes have so far been elusive. Catastrophic aggradation in the wake of two historically documented medieval earthquakes and one inferred from trench studies underscores that Himalayan valley fills should be considered as potential archives of past earthquakes. Such valley fills are pervasive in the Lesser Himalaya though high erosion rates reduce

  12. Tristan and Isolde, or On the Conventions and Liberties of Medieval Eros

    Full Text Available Although written by men, medieval literature, whose main invention isassociated with courtly love, seems to be the echo of women’s Eros-relatedBovarism. Having a status of servitude in society, the medieval woman ispraised in literature. She becomes an object of adoration in a conventionthat follows the principles of feudal behaviour, but offers to the followingcenturies a fundamental lesson about love – a love which involves distanceand platonicism. In this context, my study aims to point to the modernity ofthe novel Tristan and Isolde, which breaks the known patterns byambiguating not only the moral medieval Manichaeism, but also the idea ofan unconsummated love and by proposing a complex female model, foreverdifferent according to the perspective from which she is perceived: thehusband’s, the lover’s, God’s.

  13. Postmortem Inventories in Medieval Valencia. A Source for the Study of Household Consumption and Living Standards

    Directory of Open Access Journals (Sweden)

    Luis Almenar Fernández

    2017-12-01

    Full Text Available Basic questions about the nature of postmortem inventories in late medieval Valencia have rarely been asked. What distinguished them from other lists of goods and what was their legal basis? Why were inventories made? Which goods were listed and which ones omitted? How many inventories are preserved today? Which sectors of medieval society requested them? The answers that this paper provides clearly show the potential of a serial and quantitative usage of the Valencian inventory for the study of household consumption, an analysis that would enable us to measure far more accurately the changes in living standards in late medieval society to a degree that is difficult to achieve in other regions of Europe.

    Full Text Available The aim of this paper is to investigate the ways people understood their body during the medieval period in Britain. I bring together the multiple different ways in which the body was treated in death, I focus on the role and power of grave goods and evidence found in dead bodies for plasticity in life to embrace the complexity of the medieval body, I examine the cultural practice of nutrition and environment affected the bodily mold. Another point I take into consideration is the practice of dietary through differentiation between male and female body in which we explore how medieval people socially and culturally constructed body based on their notion and understanding of gender identity. In addition, religion had a great influence on people’s understanding to deal with dead bodies and I concentrate on how bodily resurrection impacted on people’s preparation for the Day of Judgment by placing the goods in burials.

  15. "By expresse experiment": the doubting midwife Salome in late medieval England.

    Science.gov (United States)

    Swann, Alaya

    2015-01-01

    This article examines late medieval English representations of the startling and apocryphal story of Salome, the skeptical midwife who dares to touch, or at least attempt to touch, the Virgin Mary "in sexu secreto" during a postpartum examination at the nativity. Salome's story originated in the second century, but its late medieval iterations are inflected by a culture interested in evaluating and examining sensory evidence, in both medicine and religion. The story appears in sermon collections, devotional texts, the cycle nativity plays, and John Lydgate's Life of Our Lady, and these variations demonstrate the intersection of gender and experience-based knowledge in medical and devotional contexts. Salome's story provides a unique opportunity to study late medieval interpretations of female medicine, materialism, and spirituality.

    2012-01-01

    The aim of this article is to highlight practical recommendations based on our experience as reviewers and journal editors and refer to some most common mistakes in manuscripts submitted to Biochemia Medica. One of the most important parts of the article is the Abstract. Authors quite often forget that Abstract is sometimes the first (and only) part of the article read by the readers. The article Abstract must therefore be comprehensive and provide key results of your work. Problematic part of the article, also often neglected by authors is the subheading Statistical analysis, within Materials and methods, where authors must explain which statistical tests were used in their data analysis and the rationale for using those tests. They also need to make sure that all tests used are listed under Statistical analysis section, as well as that all tests listed are indeed used in the study. When writing Results section there are several key points to keep in mind, such as: are results presented with adequate precision and accurately; is descriptive analysis appropriate; is the measure of confidence provided for all estimates; if necessary and applicable, are correct statistical tests used for analysis; is P value provided for all tests, etc. Especially important is not to make any conclusions on the causal relationship unless the study is an experiment or clinical trial. We believe that the use of the proposed checklist might increase the quality of the submitted work and speed up the peer-review and publication process for published articles.

    2004-01-01

    The objective of this study was to evaluate the irritant potential of propolis, Casearia sylvestris, Otosporin and saline solution (control). Twenty-eight male Wistar rats were selected, anesthetized and four experimental sites were designed on their backs. Injections of 2% Evans blue were intravenously administered in the lateral caudal vein and 0.1 ml of the tested solutions was injected intradermally into the experimental sites. The animals were killed 1/2, 1, 3 and 6 hours after the injection of the solutions. Each piece of skin containing the lesion was immersed in formamide and incubated at 45 masculine C for 72 h. After filtration, optical density was measured in a spectrophotometer. Data were statistically analyzed by a 2-way non-parametric test. The highest values of extracted dye were observed at 3 hours characterizing a peak in the inflammatory process. Propolis was the least irritant solution. The natural medicaments tested in this study may be a valuable alternative for endodontic treatment.

    Full Text Available Context: Antisepsis achieved through appropriate use of irrigants is essential for endodontic success. Identification of newer anti-bacterial agents gives alternatives to clean the canal as eradication of the infection prior to obturation does affect prognosis. Objective: Comparison of the anti-bacterial action of 3.8% silver diamine fluoride and 2% chlorhexidine gluconate against Enterococcus faecalis in root canals. Materials and Methods: Forty-four single-rooted teeth were decoronated, and the root section was enlarged with peeso-reamer (No: 3 to standardize length and diameter. The samples were then autoclaved and divided into two study groups and two control groups. Enterococcus faecalis ATCC 29212 was inoculated into all test samples for 72 hours. The samples were enlarged with peeso-reamer (No: 5 after placement of respective medicament for 24 hours. Shavings were collected and inoculated on Brain Heart Infusion agar for 24 hrs to measure the colony forming units. Results: Both 3.8% silver diamine fluoride and 2% chlorhexidine showed a superior capacity to sterilize the root canals than control groups. Conclusion: The use of silver diamine fluoride as an endodontic irrigant is feasible as it can effectively remove the microbes present in the canal and circumpulpal dentin.

    2015-06-01

    We report an eco-friendly method for the synthesis of copper nanoparticles (CuNPs) using Citron juice (Citrus medica Linn.), which is nontoxic and cheap. The biogenic copper nanoparticles were characterized by UV-Vis spectrophotometer showing a typical resonance (SPR) at about 631 nm which is specific for CuNPs. Nanoparticles tracking analysis by NanoSight-LM20 showed the particles in the range of 10-60 nm with the concentration of 2.18 × 10(8) particles per ml. X-ray diffraction revealed the FCC nature of nanoparticles with an average size of 20 nm. The antimicrobial activity of CuNPs was determined by Kirby-Bauer disk diffusion method against some selected species of bacteria and plant pathogenic fungi. It was reported that the synthesized CuNPs demonstrated a significant inhibitory activity against Escherichia coli followed by Klebsiella pneumoniae, Pseudomonas aeruginosa, Propionibacterium acnes and Salmonella typhi. Among the plant pathogenic fungi tested, Fusarium culmorum was found to be most sensitive followed by F. oxysporum and F. graminearum. The novelty of this work is that for the first time citron juice was used for the synthesis of CuNPs.

    2013-01-01

    The study evaluated the effects of 3 percent sodium hypochlorite (NaOCl) and formocresol (FC) as pulp dressing agents in pulpotomized primary molars. One hundred children between three and six years each with at least one primary mandibular second molar requiring pulpotomy were randomly allocated to two groups (of 50 each). All the teeth received stainless steel crown after conventional pulpotomy procedure with either NaOCI (applied for 15 second) or FC (applied for one minute). Clinical and radiographic signs/symptoms were blindly recorded at zero, six. and 12 months. The differences were statistically analyzed using the Fisher's exact test. At six months, 100 percent clinical success was found with both NaOCl, and FC. Radiographic success rates for NaOCl were 98 percent and 92 percent at 6- and 12-month recalls respectively. FC group showed 94 percent and 93 percent radiographic success rates at the same periods respectively. There was no statistically significant difference between the groups. NaOCl can be suggested as a pulpotomy agent for primary teeth pulpotomies. However further clinical studies with long-term follow-ups are needed to test the efficacy of NaOCl as a pulpotomy medicament in primary teeth.

    The aim of this study was to compare the effect of white mineral trioxide aggregate (MTA) to that of formocresol (FC) as pulp dressing agents in pulpotomised primary molars. In this clinical trial study, 60 lower second primary molars of 46 children were treated by a conventional pulpotomy technique. The teeth were randomly assigned to the MTA (experimental) and FC (control) groups by random numbered table. Following removal of the coronal pulp and haemostasis, the pulp stumps were covered with an MTA paste in the experimental group. In the control group, FC was placed with a cotton pellet over the pulp stumps. The teeth of both groups were restored with stainless steel crowns. Children arrived for clinical and radiographic follow-up evaluation after 6, 12 and 24 months. The treated teeth in FC group (n = 18) were clinically and radiographically successful after 24 months. The radiographic follow-up evaluation revealed one failure (furcation involvement) in 18 molars treated with MTA after 24 months. The treated teeth in MTA group were clinically successful 24 months postoperatively. Pulp canal obliteration was observed in one of the teeth treated with MTA and four of the teeth treated with FC. MTA could be used as a safe medicament for pulpotomy in cariously exposed primary molars and could be a substitute for FC.

    A ready-made dry medium method for aerobic count, the MediCa AC method, was compared to the AOAC Official Method 966.23, Microbiological Methods, for seven different heat-processed meat matrixes: cooked roast beef, Chinese barbecued pork (barbecued pork seasoned with honey-based sauce), bacon, cooked ham, frankfurter (made from beef and pork), and boiled and cooked pork sausage. The 95% confidence interval for the mean difference between the two methods at each contamination level for each matrix fell within the range of -0.50 to 0.50, and no statistical difference was observed at all three contamination levels for five matrixes. These results demonstrate that the Medi-Ca AC method is a reasonable alternative to the AOAC 966.23 method for cooked meat products.

    2012-01-01

    This article presents new data on mortality in the late medieval period, and suggests methodologies for analysing incomplete datasets. Using data collated from the records of Winchester College this study follows the lives of 2,692 individuals, and analyses adolescent mortality in the sample group for the period 1393-1540. This study of mortality among 10-18 year olds is the first of its kind to produce data for a sample of adolescents in late medieval England, and thereby contributes significant new data to our understanding of late medieval mortality. These data are placed within the context of that obtained for other medieval population samples, most notably with studies of medieval monastic groups.

    Conclusion: It can be concluded from this study that the control group showed least amount of leakage, whereas the 1% chlorhexidine gel group showed maximum amount of leakage. Apical leakage was observed with all the experimental groups with little variations in between them. Under the parameters of this study, it can be concluded that use of intracanal medicaments during endodontic treatment has a definite impact on the apical seal of the root canal system.

    Full Text Available Although a rare occurrence in late medieval cemeteries, vessels have been found on almost all major sites of the period, such as Novo Brdo, Trgovište, Reljina Gradina and the churchyard of St Peter’s near Novi Pazar, the churchyard of St Nicholas’ at Kuršumlija, the churchyard of St Stephen’s at Milentija near Brus, Mali Zvečan, Mirijevo, Vinča. Vessels occur in different places, both on top of and in graves. Fragments of pottery and glass vessels are relatively abundant in layers of earth filling burial pits and chambers, and in those immediately overlaying burial pits or gravestones. The available data make it possible to recognize almost all functional types. The most frequently found pottery shapes are larger liquid containers - jugs and pitchers, and apparently there have also been many pots, both hearth cooking and glazed (figs. 1-3; 5-9. Recognizable among the glass vessels are bottles, usually those with long fluted necks and biconical, as well as infrequent icon lamps. The data about the vessels found buried with the deceased is much more detailed. Such finds are recorded at Mačvanska Mitrovica (fig. 10/3, Brestovik (fig. 13/3, Mirijevo (fig. 4/1, Vinča (figs. 4/2; 10/4, Stragari near Kragujevac, Milentija near Brus, round the church of St Peter near Novi Pazar, at the monastery of Končulić (fig. 13/2 and the monastery of Gradac. The relatively plentiful and diverse vessels discovered at the cemeteries of medieval Trgovište are especially illustrative (fig. 10/2, 7. The available descriptions of vessels and archaeological contexts provide a general impression about the types of vessels recorded in the cemeteries of a late medieval and early modern date in the central Balkans. Glass bottles as a rule were laid in graves, while earth-fill layers, apart from bottles, contained plentiful shards of drinking vessels. As for the bottles, two types were registered: biconical and those with long fluted necks (figs. 10; 12/1. Among

  9. Anguish and Acedia as Disorders in Medieval Monasticism, Examples and Curative Resources

    2017-12-01

    Full Text Available The spiritual and mental disorders typical of medieval monasticism had a common symptomatology expressed in anguish concerning their own existence, known as acedia. The therapeutic response of medieval monks to this situation involved certain liturgical variations, understood as therapeutic representation and as the healing word, both derived from the curatio verbi of the monks in the Egyptian desert. It is, in short, the performative capacity of liturgy. In this paper my objective is to present the most significant features of acedia in Christian monasticism and to analyze three liturgical texts as therapeutic instances of this disorder.

    Science.gov (United States)

    Riha, O

    1996-01-01

    Relying on their patients' complaints, medieval physicians did not discriminate theoretically between sickness and health. As for the types of illness, there were two different concepts of disease: The semiotic tracts (sphygmology, uroscopy, hematoscopy) describe signs of dyscrasia and locus affectus, while the medical handbooks combine symptoms like fever, pain, nausea, constipation etc. with the signs of pulse, urine and blood. The term "diagnosis" should be used only for this latter type of disease. Because of the ancient model of humoral pathology and because of the deductive construction of symptomatology, "medieval" illnesses cannot be compared with "ours".

    Full Text Available The medieval knight was required to perform the same physical exercices and have the same capabilities as Spartan, Athenian and Roman soldiers. They had to be agile, strong, fast and able to use weapons on foot as on horseback. To be pysically fit was as important as knowing history as explained by tutors and sung by jugglers in moments of leisure during which they learnt of legends, nationals heroes and the paradigms that distinguish nations. All the heroes praised through generations provide models shaped the collective personality of entire peoples. San Isidoro de Sevilla, Ramón Llull, King Alfonso X the Wise and Don Juan Manuel were the principal writers to exalt the figure of the knight and his education. During the XII, XIII, XIV and XV centuries and including the Renaissance, there were exhibitions of physical games, during which knights sought fame and fortune: jousts, tournaments, staged games, games using canes and processions of arms called «pasos honrosos» were undertaken with popular enthusiasm in Western and central Europe in the Byzantine Empire and throughout the Moslem world.Los ejercicios y habilidades físicas exigidos al caballero medieval fueron semejantes a los que se pedían al militar espartano, ateniense y romano. Debían ser ágiles, fuertes, rápidos y diestros en el manejo de las armas a pie y a caballo. Tan importante como una buena forma física era conocer la Historia cantada por ayos y juglares en los momentos de ocio, a través de la cual se familiarizaban con las tradiciones, leyendas, héroes nacionales y los paradigmas que distinguían a un pueblo de otro.

    Full Text Available Abstract Background Sinorhizobium meliloti and S. medicae are symbiotic nitrogen fixing bacteria in root nodules of forage legume alfalfa (Medicago sativa L.. In Morocco, alfalfa is usually grown in marginal soils of arid and semi-arid regions frequently affected by drought, extremes of temperature and soil pH, soil salinity and heavy metals, which affect biological nitrogen fixing ability of rhizobia and productivity of the host. This study examines phenotypic diversity for tolerance to the above stresses and genotypic diversity at Repetitive Extragenic Pallindromic DNA regions of Sinorhizobium nodulating alfalfa, sampled from marginal soils of arid and semi-arid regions of Morocco. Results RsaI digestion of PCR amplified 16S rDNA of the 157 sampled isolates, assigned 136 isolates as S. meliloti and the rest as S. medicae. Further phenotyping of these alfalfa rhizobia for tolerance to the environmental stresses revealed a large degree of variation: 55.41%, 82.16%, 57.96% and 3.18% of the total isolates were tolerant to NaCl (>513 mM, water stress (-1.5 MPa, high temperature (40°C and low pH (3.5, respectively. Sixty-seven isolates of S. meliloti and thirteen isolates of S. medicae that were tolerant to salinity were also tolerant to water stress. Most of the isolates of the two species showed tolerance to heavy metals (Cd, Mn and Zn and antibiotics (chloramphenicol, spectinomycin, streptomycin and tetracycline. The phenotypic clusters observed by the cluster analysis clearly showed adaptations of the S. meliloti and S. medicae strains to the multiple stresses. Genotyping with rep-PCR revealed higher genetic diversity within these phenotypic clusters and classified all the 157 isolates into 148 genotypes. No relationship between genotypic profiles and the phenotypes was observed. The Analysis of Molecular Variance revealed that largest proportion of significant (P Conclusion High degree of phenotypic and genotypic diversity is present in S

Estas materias primas no son solubles al agua, lo que las hace particularmente adecuadas para las composiciones de gres porcelánico tradicional producido por vía húmeda. Sin embargo, existe un gran grupo de materias primas solubles que también tienen un gran potencial como fundentes y que podrían utilizarse en los procesos de vía seca. En este contexto, el objetivo de este trabajo ha sido determinar el potencial fundente de las materias primas solubles al agua, o parcialmente solubles al agua, en una composición de gres porcelánico. La efectividad de varios boratos, es decir, la colemanita, la ulexita, la hidroboracita, así como el carbonato sódico, fueron ensayados en un estudio de tipo comparativo. Los resultados de este estudio indican que la incorporación de pequeñas cantidades de estos fundentes es suficiente para reducir la temperatura de cocción de forma importante, sin causar una alta deformación piroplástica de los soportes. Los mejores resultados se obtuvieron con las composiciones que contenían hidroboracita. Este resultado es especialmente relevante para la creación de composiciones alternativas de piezas de gres porcelánico producidas por vía seca. El proceso de vía seca es, en la actualidad, un tema de especial interés, debido a las cuestiones medioambientales y económicas.

  17. Padua and the Stars: Medieval Painting and Illuminated Manuscripts

    Canova, G. M.

    2011-06-01

    In the Middle Ages, the University of Padua was one of the most prominent centre for astrological studies in Europe. The Paduan doctor and philosopher, Pietro d'Abano, who lived in the first decades of the 14th century, was the main figure in this field. At the end of the 13th century, during a long stay in Paris, he got in contact with the new astrological doctrines flourished after the translation into Latin of Ptolemy's and Arab's works in Spain. Thus, when he went back to Padua, he published several studies on the influence of celestial bodies on human life and human physical characteristics and psychology. These ideas deeply affected the Paduan society of the 14th century and, consequently, the most important painters chose or were asked to evoke the images of stars, planets, and their properties. This adventure began with Giotto who shows a surprising interest in celestial bodies in the Scrovegni Chapel where he represented a comet, and soon after he produced a cycle of astrological paintings on the vault of the Palazzo della Ragione in the Public Palace of Padua. Unfortunately, in 1420, these paintings were destroyed in a fire, but the magnificent cycle of astrological frescoes realized soon after on the walls of the same room gives us some clues on Giotto's work and shows us the complexity of the Medieval astrological science. Other astrological paintings, still preserved, were realized by the painters of the Carrarese Court such as Guariento, who painted the planets and their influences on human ages in the church of the Eremitani, and Giusto dei Menabuoi who represented a superb zodiac around a realistic map of Earth in the Cathedral Baptistery. So Padua really became the capital of astrological painting in Europe. Other evidence of the astrological image in the Veneto Region, between the 14th and 15th centuries, can be found in the manuscripts illuminated in the milieu of the University of Padua and in the first books printed in Venice.

  18. Farmsteads in early medieval Germany – architecture and organisation

    Directory of Open Access Journals (Sweden)

    Schreg, Rainer

    2012-12-01

    Full Text Available In Germany early medieval rural settlements are known from a rising number of excavated sites. Rural architecture was a wooden architecture. Only churches were built in stone. A farmstead consisted of several buildings: the main house and several economic buildings as pit houses and storages. Before the 1980s, when large scale excavations became more and more common, there was little awareness of changes in rural settlement history. The formation of still existing villages was only late in the Middle Ages. However, even today it is difficult to understand the changes in rural architecture as there are distinct regional differences. Probably the 5th century on the one hand and the period of village formation between the 10th and 13th centuries on the other hand were the most innovative periods. This article provides a short characteristic of buildings and settlement organisation. He gives an outline of research history and identifies some recent trends and future perspectives of research.Tenemos conocimiento de los asentamientos rurales de la alta Edad Media en Alemania gracias a un número creciente de excavaciones arqueológicas. La arquitectura rural es una arquitectura de madera, reservándose la piedra para las iglesias. Las alquerías comprendían varias edificaciones: la casa principal y varias construcciones destinadas a fines económicos, como las viviendas semienterradas y almacenes. Antes de los años 80 del siglo pasado, cuando las excavaciones a gran escala se hicieron más habituales, se conocía poco sobre la evolución de la historia de los asentamientos rurales. Las aldeas que aún permanecen se formaron a finales de la Edad Media e incluso hoy resulta difícil entender los cambios que se produjeron en la arquitectura rural cuando existen diferencias regionales. Es probable que el periodo comprendido entre el siglo V, por una parte, y los siglos X y XIII por otra fue la de mayor innovación. El presente artículo ofrece un

    Dzukou Valley, Nagaland is one of the biodiversity rich regions in northeast India. It is house to 113 families of plants where primitive angiosperms and endemic plants species contribute 19% and 6% respectively to this unique floristic wealth. Floristic uniqueness of the valley is that 50 families are represented by single genus and 128 genuses are represented by single species. Present work is the first attempt to use soil organic matter (SOM) d13C and pollen data to understand climate vis-à-vis vegetation dynamics in an area where climatic changes were not strong enough to induce a significant change in vegetation cover. The d13C values in our study range from -29.1‰ to -27.7‰ during late Holocene. These values are typical of forest soils and suggest organic carbon derived exclusively from C3 vegetation. Generated proxy data reveals three phases of climatic and vegetational shifts in the region since 3100 yr BP. During the first phase from 3100 yr BP to 2300 yr BP isotope data shows higher values, indicating towards a comparatively dry climate and area was occupies by dry Pine-Oak forest. Subsequently in second phase from 2300 yr BP to 1060 yr BP increase in arboreal pollens (tree elements) and gradually decreasing trend in d13C values from 2300 to 1060 yrs BP by 1.4 ‰ indicate towards comparatively moist climatic conditions corresponding to Medieval Warm Period. Later on in the third phase from 1060 yr BP onwards climate again climate turned dry and continued till date as postulated from the increasing trend in d13C values and good recovery of Pinus-Oak forest pollens.This study holds its significance not only as the first attempt to address palaeoclimate and palaeo-vegetation study from Nagaland but also as the first attempt to use SOM d13C along with pollen data to understand the influence of fluctuating rainfall (in a high rainfall zone) in altering the floristic wealth of a region. This type of study is essentially needed to address several issues

    Full text: Recent developments in X-Ray Fluorescence micro-analysis techniques made the traditional range of XRF applications expand, benefiting from the combination of single point analysis with high spatial element imaging. The sample is scanned through the X-Ray beam and corresponding spectra are continuously read from the detector and correlated to a particular position on the sample. In this work, elemental concentrations were obtained by X-ray fluorescence (XRF) technique (Jobin Yvon Horiba XGT-5000 instrument) offering detailed elemental analysis. The instrument is equipped with a tungsten X-ray tube and a beryllium window, operating at 50 kV with a beam collimator of 100{mu}m in diameter to irradiate the sample and with a Si detector. Tooth mapping provided semi-quantitative information and highlighted the regions of interest. Then multi-points analysis was used to obtain quantitative results on calcium, phosphorus, strontium and iron. As the chemical composition of dental tissues is similar to the one of bone tissue, the certified reference materials NIST SRM 1400 Bone Ash and NIST SRM 1486 Bone Meal were used for calibration. In this study, only permanent first molars were selected for analysis. The material comes from the medieval cemetery (XII{sup th} . XIII{sup th}) of Feldioara (Bra.ov County, Romania). In the same time, modern teeth were used as reference. The top of the tooth was removed using a diamond disk, with a cut lying perpendicular to the dental cusps, creating a flat transversal surface to be characterized. XRF elemental (Ca, P, Sr, Fe) and ratio (Ca/P, Sr/Ca, Sr/Fe) distribution images for dental tissues (enamel and dentin) were obtained from past and modern teeth with and without caries and the results are presented and discussed. The analysis of the spatial element distribution in the teeth tissues revealed severe alterations in elemental composition of both enamel and dentin from the regions affected by caries that were confirmed by the

  1. On the Jewish Nature of Medieval Spanish Biblical Translations Linguistic Differences between Medieval and Post-Exilic Spanish Translations of the Bible

    2010-06-01

    Full Text Available A linguistic comparison of medieval Spanish translations of the Hebrew Bible and the Constantinople and Ferrara post exilic Ladino translations reveals systematic lexical and grammatical variations. These differences can be explained by the population groups to which the translations were targeted: Christian for the medieval translations; Jewish (or former converso for the post-exilic ones. The conclusion is that the medieval translations are not Jewish in nature and could therefore not have been a source for the post-exilic versions which were based on oral tradition.

    Una comparación lingüística de las traducciones hispano-medievales de la Biblia hebrea y las postexílicas de Constantinopla y Ferrara revela variaciones sistemáticas léxicas y gramaticales. Esas diferencias pueden explicarse por la audiencia a las que iban dirigidas dichas traducciones: cristiana, en el caso de las medievales; judía (o exconversa en el de las post-exílicas. La autora concluye que las traducciones medievales no son judías, por naturaleza, y en consecuencia, no podrían haber sido una fuente para las versiones post-exílicas que estaban basadas en la tradición oral.

  11. Long life, natural death. The learned ideal of dying in late medieval commentaries on Avicenna's Canon.

    Science.gov (United States)

    van 't Land, Karine

    2014-01-01

    Within late medieval learned medicine, natural death functioned both as a theoretical concept and as a goal for practice. Late medieval commentaries on Avicenna's Canon are used as source material in this study, in order to investigate the ways in which these learned medical authors envisaged natural death. The findings are compared to descriptions of natural death by natural philosophers, and to ideals of dying in broader medieval culture. According to the physicians, natural death was caused by the extinction of innate heat, due to a lack of innate moisture. They discussed natural death in relation to regimen, as the right regimen protected the body's heat and moisture, and thus helped a patient to keep natural death aloof. So, in order to think about natural death, the physicians turned to the whole of life, during which heat dried out moisture and regimens ought to be followed. By contrast, natural philosophers tended to focus on the moment of death itself. The comparison of natural death with the Good Death in broad medieval culture highlights the amoral nature of the natural death.

  13. Measuring the Measuring Rod: Bible and Parabiblical Texts within the History of Medieval Literature

    Directory of Open Access Journals (Sweden)

    Lucie Doležalová

    2018-01-01

    Full Text Available In spite of the acknowledged crucial role it had in forming medieval written culture, the Bible and a wide-range of parabiblical texts still remain largely ignored by histories of medieval literatures. The reason for this striking omission of an important group of medieval texts from the 'canonical' narratives is, as I argue, the strong bias in favour of national, secular, fictional, and original texts which shapes literary studies – an inheritance from the nineteenth-century nationalising approaches discussed in the first issue of the Interfaces journal. Of course, the discipline of literary studies and therefore selection, hierarchization, and interpretation are complex social, cultural and political processes where almost anything is possible. It is the environment, the interpretive community, in which the interpretation takes place that has a decisive role. And that, too, is constantly being transformed. Thus, there are no final categories and answers because as long as there are interpretive communities, meanings are generated and operate in new ways. That is why the present discussion does not aim to claim that many of the parabiblical texts are literature and should have been included in the canon of medieval literature. Rather, I examine what the nineteenth-century notion of canon did to these texts and how the current questioning and substantial reshaping of notions of canon can transform our understanding of parabiblical texts.

  16. Temporal trends in vertebral size and shape from medieval to modern-day.

    Directory of Open Access Journals (Sweden)

    Juho-Antti Junno

    Full Text Available Human lumbar vertebrae support the weight of the upper body. Loads lifted and carried by the upper extremities cause significant loading stress to the vertebral bodies. It is well established that trauma-induced vertebral fractures are common especially among elderly people. The aim of this study was to investigate the morphological factors that could have affected the prevalence of trauma-related vertebral fractures from medieval times to the present day. To determine if morphological differences existed in the size and shape of the vertebral body between medieval times and the present day, the vertebral body size and shape was measured from the 4th lumbar vertebra using magnetic resonance imaging (MRI and standard osteometric calipers. The modern samples consisted of modern Finns and the medieval samples were from archaeological collections in Sweden and Britain. The results show that the shape and size of the 4th lumbar vertebra has changed significantly from medieval times in a way that markedly affects the biomechanical characteristics of the lumbar vertebral column. These changes may have influenced the incidence of trauma- induced spinal fractures in modern populations.

    The population history of the East Slavs is complicated. There are still many unanswered questions relating to the origins and formation of the East Slavic gene pool. The aims of the current study were as follows: (1) to assess the degree of biological affinity in medieval East Slavic tribes and to test the hypothesis that East Slavic peoples have a common origin; (2) to show their genetic connections to the autochthonous populations of the northern part of Eastern Europe (Baltic and Finno-Ugric tribes); and (3) to identify a genetic continuity between the bearers of Chernyakhov culture and medieval Eastern Slavs. In this study, nonmetric cranial trait data for medieval East Slavic tribes and comparative samples from unrelated groups were examined. Analyzes of phenotypic differentiation were based on Nei's standard genetic distance and hierarchical GST statistics. The results obtained suggest that the genetic affinity of the East Slavic tribes is due not only to inter-tribal gene flow, but is, more importantly, a result of their common population history. Evidence of gene flow from the Baltic and Finno-Ugric groups was showed in the gene pool of Eastern Slavs, as was genetic continuity between medieval East Slavic tribes and the populations of the preceding Chernyakhov culture. These findings support a "generalizing" hypothesis of East Slavic origin, in which a Slavic community was formed in some particular ancestral area, and subsequently spread throughout Eastern Europe.

  9. Historia and materia: the philosophical implications of Francis Bacon's natural history.

    Science.gov (United States)

    Giglioni, Guido

    2012-01-01

    This article examines the philosophical implications underlying Bacon's views on historical knowledge, paying special attention to that variety of historical knowledge described by Bacon as "natural." More specifically, this article explores the interplay of history (historia) and fable (fabula). In the sphere of thought, fabula is the equivalent to materia in nature. Both are described by Bacon as being "versatile" and "pliant." In Bacon's system of knowledge, philosophy, as the domain of reason, starts from historiae and fabulae, once memory and the imagination have fulfilled their cognitive tasks. This means that, for Bacon, there is no such thing as a pure use of reason. He advocates a kind of reason that, precisely because it is involved with matter's inner motions (its "appetites," in Bacon's characteristic language), is constitutively 'impure'. The article shows how the terms historia and fabula cover key semantic areas in defining Bacon's philosophy: historia may mean "history" as well as "story,"fabula "myth" as well "story". In both cases, we can see significant oscillations from a stronger meaning (close to those of matter and nature) to a weaker one (connected to wit and imagination), as if the power of nature decreases moving from histories and myths to stories. On the other hand, there are cases in which Bacon seems to stick to a diachronic view of the meaning of fables and histories, such that the transition from myths to history, especially natural history, is described as a collective effort towards reality and enlightenment.

    Full Text Available Este artículo se centra en el problema de la definición y los límites de las competencias legislativas del municipio en materia de ambiente. El marco regulatorio es la Constitución Federal de 1988. La referencia empírica son las leyes locales que rigen el uso de bolsas de plástico, con la finalidad y justificación de la protección del medio ambiente, y las decisiones judiciales acerca de la constitucionalidad de las leyes. Se argumenta que, si bien no existe una disposición expresa en la Constitución brasileña, el principio de subsidiariedad puede ser deducido del modelo federativo esbozado en la Constitución, por lo que es un principio clave para orientar la función legislativa del Municipio en el ámbito ambiental. Adopta una metodología analítica y sistemática, que comprende los aspectos conceptuales, normativos y empíricos del problema.

  11. I concetti di "materia", "forma" e "ordine" nel pensiero teorico musicale medievale e contemporaneo

    Directory of Open Access Journals (Sweden)

    2011-01-01

    Full Text Available La dimensione teorica della musica occidentale, nella sua evoluzione storica, ha inevitabilmente fatto uso di concetti essenziali alla definizione di come il suono è musicalmente organizzato o organizzabile. Fra questi, risultano imprescindibili le nozioni di materia, forma e ordine, che implicano rispettivamente, nei pur diversi ambiti linguistici e contesti storico-filosofici di riferimento, ciò di cui è fatta la musica, ciò a cui la materia sonora tende, e come tale tensione è realizzata. Scopo di questo contributo è una valutazione d’insieme sulla valenza filosofica e l’uso di tali concetti nel pensiero musicale occidentale altomedievale e in quello del Novecento, che nonostante la distanza cronologica presentano convergenze significative. Nel Medioevo, un lungo processo di elaborazione teorico-pratica permise la matematizzazione dello spazio (e, più tardi, anche del tempo musicale, attraverso l’adattamento di moduli melodici, trasmessi oralmente, alle strutture scalari desunte dalla teoria greco-boeziana. La forma e l’ordo musicali furono quindi riferiti ai criteri fisico-matematici atti a distinguere nella materia sonora, in sé disorganica e indefinita, ciò che è musicale da ciò che non lo è. Tale concezione sparisce con l’affermarsi del sistema tonale, ove il suono fisico è concepito come “pre-formato” e “pre-ordinato” nella gamma scalare e nei vincoli attrattivi “naturali” degli armonici. In conseguenza, i concetti di forma e ordine abbandonano il contesto acustico, andando a definire i criteri teorici della composizione artistica, in linea con l’idea filosofica del loro esprimere la coerenza logico-sintattica dell’“insieme organico” (la Formenlehre teorizzata da Widmann. Nell’ambito del pensiero musicale del Novecento, la crisi del sistema tonale e la messa a punto di nuove modalità e tecniche di produzione del suono hanno riorientato la valenza significante e l’uso di questi tre concetti

  12. Flower symbolism and the cult of relics in medieval Serbia

    Full Text Available The Life of archbishop Eustathios I [Jevstatije] (1279-1286, deserving head of the medieval Serbian Church and a saint, is a very interesting source for studying the cult of relics with the Serbs. This is not surprising considering that the Life was penned by one of the most illustrious of Eustathios' successors on the church throne, Daniel II [Danilo], a learned Athonite and unquestionable master of the hagiographie literary genre. In his account of the life of his distinguished predecessor, Daniel describes extensively the events constituting the key stage in the glorification of a saint, namely Eustathios' death and posthumous occurrences at his grave. As most holy men, Eustathios foresaw his own death, and he departed from this world serenely. He was buried, with due honours, in the 'marble grave' he had prepared for himself in the cathedral church of Holy Saviour at Žiča. In keeping with the well-established saint-making process, a few years after the funeral 'extraordinary signs' began to occur at the archbishop's grave, in this particular case, candlelight and a multitude of murmuring voices followed by the miraculous cure of an incurably ill person. These occurrences preceded the great miracle which, to the best of my knowledge, is unparalleled in the medieval Serbian practice of relic veneration. Namely, 'one day they found growing from his marble grave three flowers endowed with wondrous beauty and impossible to liken to anything else. For, indeed, they were not of earthly humidity or of union with flowers that grow from earth; but, o wonder, how a dry stone standing for so long in the church could send forth fragrant flowers, to the renewal of the sanctified one's body'. Flower metaphors occur in the Service to the holy archbishop Eustathios, yet another piece penned by Daniel II, notably in his paraphrases of Psalm 92, 12-14 ('The righteous shall flourish like the palm tree: he shall grow like a cedar in Lebanon. These that be

    Tree-ring records provide one of most reliable means of reconstructing past climatic conditions, from longer-term multi-decadal fluctuations in temperature and precipitation to inter-annual variability, including years that experienced extreme weather. When combined with written records of past societal behaviour and the incidence of major societal stresses (e.g., famine, disease, and conflict), such records hold the potential to shed new light on historical interactions between climate and society. Recent years have seen the continued development of long dendroclimatic reconstructions, including, most recently the development of the Old World Drought Atlas (OWDA; Cook et al., 2015) which for the first time makes available a robust reconstruction of spring-summer hydroclimatic conditions and extremes for the greater European region, including the entirety of the Dark Ages. In this paper, we examine the association between hydroclimatic extremes identified in the OWDA and well-dated reports of severe drought in early medieval European annals and chronicles, and find a clear statistical correspondence, further confirming the accuracy of the OWDA and its importance as an independent record of hydroclimatic extremes, a resource that can now be drawn upon in both paleoclimatology and studies of climatic impacts on human society. We proceed to examine the association between hydroclimatic extremes identified in the OWDA and the incidence of a range of major societal stresses (scarcity and famine, epidemic disease, and mass human mortality) drawn from an exhaustive survey of early medieval European annals and chronicles. The outcome of this comparison firmly implicates drought as a significant driver of major societal stresses during early medieval times. Using a record of the violent killings of societal elites recorded on a continuous annual basis in medieval Irish monastic annals, we further examine the role of hydroclimatic extremes as triggers in medieval violence

  14. Population-specific stature estimation from long bones in the early medieval Pohansko (Czech Republic).

    We tested the effect of population-specific linear body proportions on stature estimation. We used a skeletal sample of 31 males and 20 females from the Early Medieval site at Pohansko (Břeclav, Central Europe) and a comparative Central European Early Medieval sample of 45 males and 28 females. We developed new population-specific equations for the Pohansko sample using anatomical reconstructions of stature, then compared percentage prediction errors (%PEs) of anatomical stature from limb bone lengths using the derived Pohansko equations with those previously derived from more general European and other Early Medieval samples. Among general European equations, the lowest %PEs for the Pohansko sample were obtained using the equations of Formicola and Franceschi: Am J Phys Anthropol 100 (1996) 83-88 and Ruff et al.: Am J Phys Anthropol 148 (2012) 601-617. However, unexpectedly, the choice between tibial latitudinal variants proposed by Ruff et al.: Am J Phys Anthropol 148 (2012) 601-617 appeared to be sex-specific, with northern and southern variants producing lower %PEs for males and females, respectively. Equations from Breitinger: Anthropol Anz 14 (1937) 249-274, Bach: Anthropol Anz 29 (1965) 12-21, and Sjøvold: Hum Evol 5 (1990) 431-447 provided poor agreement with anatomical stature. When applied to the comparative Central European Early Medieval sample, our new formulae have generally lower %PE than previously derived formulae based on other European Early Medieval samples (Maijanen and Niskanen: Int J Osteoarchaeol 20 (2010) 472-480; Vercellotti et al.: Am J Phys Anthropol 140 (2009) 135-142. The best agreement with anatomical stature among our newly developed equations was obtained using femoral+tibial length, followed by femoral length. Upper limb bone lengths resulted in higher %PEs. Variation in the tibia is likely to contribute most to potential bias in stature estimation. Am J Phys Anthropol, 2015. © 2015 Wiley Periodicals, Inc. © 2015 Wiley

    Full Text Available Background: Repeated endodontic failures are due to pathogens like Enterococcus faecalis and Candida albicans which are resistant to the common intracanal medicaments like calcium hydroxide (Ca[OH] 2 . Aims: To determine the role of commonly used folk medicine, Spilanthes acmella (SPA against root canal pathogens like E. faecalis, C. albicans, Staphylococcus aureus, Streptococcus sp, and to compare its efficacy with Ca(OH 2 , a popularly used intracanal medicament. Materials and Methods: Bacterial strains of S. aureus, Streptococcus sp., E. faecalis, and fungal strains of C.albicans were tested against different concentrations of SPA and Ca(OH 2 . Seven days old cultures of test organisms were seeded onto agar plates and uniformly spread with a spreader. Five to six wells (8 mm were made on agar plate to which different concentrations of the test solutions were added. The inoculated plates were kept in an incubator at 37°C for 48 h and inhibition zones were measured. Statistical Analysis: Results of SPA were compared with results of Ca(OH 2 statistically using Mann-Whitney U test. Results: A significant zone of inhibition was obtained with SPA and was found to increase as the concentration increased for C. albicans. SPA showed a significant zone of inhibition at 2-5% and 10% whereas Ca(OH 2 showed a zone of inhibition only at 10% for E. faecalis. SPA showed a zone of inhibition only at 10%, whereas, Ca(OH 2 showed a significant zone of inhibition at 5% and 10% for S. aureus and Streptococcus sp., respectively. Conclusion: SPA possesses remarkable antibacterial and antifungal activity against common root canal pathogens which are responsible for repeated endodontic failures such as E. faecalis and C. albicans when compared with medicaments like Ca(OH 2 .

    The current investigations on the treatment of worn-out medicaments in Mexico, reveal that most of these treatments are carried out with the purpose to reduce the packing and diminish the toxic level that presents each one of those medicaments. That it reach to reuse of them is their packing material and/or their cover. Once treated, the worn-out medicaments move to a sanitary filler. With relationship to the investigation works that have been carried out for the manganese removal in solution, they show a great number of materials that they are used for this end, as well as the parameters that influence in the process, such as the concentration of the element, the solution type in that is content and the pH. However, it is not mentioned in none of them the reuse of the worn-out medicaments (Talcid and Melox), as adsorbent materials for the removal of metals from the water. To carry out the present investigation they were selected therefore, to the one Talcid and the Melox because its present adsorbent properties, with the purpose to remove the manganese like water pollutant. Once that the worn-out medicaments were obtained, they put on in contact with different organic solvents, to obtain the active principle, due to the pharmaceutical presentation of the two medicaments that was obtained was in suspension. The active principles of the two medicaments were characterized by means of high vacuum scanning electron microscopy (SEM), elementary microanalysis (EDS) and X-ray diffraction (XRD). The experimental part consisted in putting in contact manganese solutions with the active principles of the worn-out medicaments, varying the time of contact and the concentration. The manganese quantification in the liquid phase carried out by means of atomic absorption spectroscopy (AAS). It was found that the kinetic model that better describes the sorption process of manganese in both worn-out medicaments (Talcid and Melox) it is that of pseudo second order. Those results of

    Neuropathic pain is supposed to be a post-renaissance described medical entity. Although it is often believed that John Fothergill (1712-1780) provided the first description of this condition in 1773, a review of the medieval Persian medical writings will show the fact that neuropathic pain was a medieval-originated concept. "Auojae Asab" [Nerve-originated Pain] was used as a medical term in medieval Persian medical literature for pain syndromes which etiologically originated from nerves. Physicians like Rhazes (d. 925 CE), Haly Abbas (d. 982 CE), Avicenna (d. 1037 CE), and Jorjani (d. 1137 CE) have discussed multiple aspects of nerve-originated pain including its classification, etiology, differentiating characteristics, different qualities, and pharmacologic and non-pharmacologic treatments. Recognizing medieval scholars' views on nerve-originated pain can lighten old historical origins of this concept.

Estudios han demostrado que estos componentes no son fácilmente removidos por medio de procesos de tratamiento convencionales como las plantas de tratamiento que emplean procesos biológicos. En este sentido el propósito de este trabajo consistió en evaluar la degradación de la materia orgánica presente en aguas hospitalarias reales aplicando ozono en diferentes condiciones de pH (3,0, 6,7, 10. Para esto se analizaron los valores de la UV254, la relación de biodegradabilidad DQO/DBO5 y el color (VIS436. Adicional a esto, se realizó un ensayo de toxicidad aguda, utilizando bulbos de cebolla común (Allium cepa L. Los resultados mostraron que con una dosis aplicada de ozono de 187 mgO3/h y valores de pH=10 la biodegradabilidad se aumento en un 70% y la toxicidad aguda se redujo en 62%, mientras que para valores de pH =3,0, se favoreció la remoción de la UV254 y el color. La aplicación de ozono demostró ser una alternativa viable para tratar efluentes hospitalarios como pretratamiento de un proceso biológico.

    To compare the efficacy of calcium hydroxide powder mixed with 0.2% chlorhexidine digluconate or mixed with normal saline as intracanal medicament in the treatment of apical periodontitis. Subjects were 55 in number aged 17 to 60 years. Two-visit conventional root canal treatment was performed on 70 teeth. The teeth were divided by randomization (balloting) into two groups: control group and experimental group, each with 35 teeth treated with calcium hydroxide mixed with normal saline or with 0.2% chlorhexidine digluconate as intracanal medicament respectively. All treated teeth were evaluated clinically and radiographically for signs and symptom of periapical infection at specified periods postoperatively. Overall efficacy of medicament was rated based on quality guidelines for endodontic treatment by the European Society of Endodontology 2006. A postoperative favorable outcome of 97.1% in the control group and 94.3% in the experimental group was observed at 6-month review. This difference was not statistically significant (p > 0.05). The use of normal saline or 0.2% chlorhexidine digluconate to mix calcium hydroxide used as intracanal medicament during endodontic treatment resulted in high postoperative favorable outcomes. Efficacy of 0.2% chlorhexidine digluconate as a vehicle for mixing calcium hydroxide as an intracanal medicament in the treatment of apical periodontitis is comparable to the efficacy of calcium hydroxide mixed with normal saline.

    Ground-penetrating Radar (GPR) and Electrical Resistivity Tomography (ERT) have been fruitfully employed for archaeological purposes. An area at the Pancorbo medieval site in Burgos (Spain) has been jointly explored by GPR and ERT in the search for the buried remains of the Pancorbo medieval village. After data collection, quality control and merging, a shallow depth of interest was identified and studied in detail. 3D resistivity simulation, considering sensible geometrical structures of the targets helped discover anomalies present in the area. On the other hand, visual GPR inspection was considerably enhanced by trace energy attribute analysis which provided a plan view of the existing anomalies. Two posterior archaeological excavations have a very good correlation between the identified anomalies and the excavated remains. The survey also provides hints for the continuation of the excavation.

    Multilayer polychrome coatings on medieval and Renaissance stone artefacts represent substantial challenges in laser cleaning. Therefore, polychromic models with classical pigments, minium (Pb{sub 2}{sup 2+}Pb{sup 4+}O{sub 4}), zinc white (ZnO), and lead white ((PbCO{sub 3}){sub 2}·Pb(OH){sub 2}) in an acrylic binder, were irradiated with a Q-switched Nd:YAG laser emitting at 532 nm. The studied medieval pigments exhibit strongly varying incubation behaviours directly correlated to their band gap energies. Higher band gaps beyond the laser photon energy of 2.3 eV require more incubative generation of defects for resonant transitions. A matching of the modification thresholds after more than four laser pulses was observed. Laser cleaning with multiple pulsing should not exceed ca. 0.05 J/cm{sup 2} when these pigments coexist in close spatial proximity.

    Red layered medieval stained glass windows on a transparent greenish substrate are characteristic of European medieval cathedrals, but few compositional analyses have been performed on the coloured layers. The PIXE technique has been performed on a red layered stained glass window obtained during the restoration works carried out in Las Huelgas Monastery in Burgos (Spain). Protons of 3 MeV with a beam of 4 x 5 {mu}m{sup 2} were used to acquire elemental maps of a cross section of the sample, in order to observe the homogeneity of the layered structure and its substrate. In our work, copper was detected as in other layered glasses but a correspondence with lower amounts of zinc has also been determined. Both elements appear enriched in the red coloured layers, while the other quantified elements have the same relative composition along the sample. Corrosion layers, due to the lead supporting structure of the window, were also found.

  17. The Impact of Devegetated Dune Fields on North American Climate During the Late Medieval Climate Anomaly

    Cook, B. I.; Seager, R.; Miller, R. L.

    2011-01-01

    During the Medieval Climate Anomaly, North America experienced severe droughts and widespread mobilization of dune fields that persisted for decades. We use an atmosphere general circulation model, forced by a tropical Pacific sea surface temperature reconstruction and changes in the land surface consistent with estimates of dune mobilization (conceptualized as partial devegetation), to investigate whether the devegetation could have exacerbated the medieval droughts. Presence of devegetated dunes in the model significantly increases surface temperatures, but has little impact on precipitation or drought severity, as defined by either the Palmer Drought Severity Index or the ratio of precipitation to potential evapotranspiration. Results are similar to recent studies of the 1930s Dust Bowl drought, suggesting bare soil associated with the dunes, in and of itself, is not sufficient to amplify droughts over North America.

  18. The basis of the modern medical hygiene in the medieval Medical School of Salerno.

    2015-01-01

    The link between hygiene and the concept of transmission of infective diseases was established earlier than the birth of microbiology, thanks to the studies of two neglected physicians of maternity clinic, Ignác Fülöp Semmelweis and Oliver Holmes, in the mid-1800s. Surprisingly, centuries earlier, a medieval women physician, Trotula de Ruggiero, introduced for the first time the notion of diseases’ prevention, highlighting the importance of the association of personal hygiene, balanced nutrition and physical activity for better health. Moreover, she was particularly concerned of hands hygiene for the midwives during child birth, to preserve the good health of both the mother and the baby. She practiced inside the medieval Medical School of Salerno, whose main text, the “Regimen Sanitatis Salerni” has an entire part dedicated to hygiene, providing hygienic precepts that anticipate the concepts derived from the revolutionary discoveries in medical science only centuries later.

  19. Three cases of feet and hand amputation from Medieval Estremoz, Portugal.

    Peri-mortem limb amputations are rarely reported in the paleopathological literature. The cases reported here concern severing of both hands and feet observed in three adult male skeletons, exhumed from the medieval Portuguese necropolis of Rossio do Marquês de Pombal, Estremoz, Portugal. The fact that they were found in the same site, in graves placed side by side, that all are young males, and that the three skeletons show similar perimortem injuries, make this a unique case meriting detailed analysis. Considering the lesions' location and pattern, as well as historical data, we hypothesize that this is a case of amputation as a consequence of judicial punishment. Estremoz was an important city in sustaining the Royal power at a regional scale during the medieval period. Copyright © 2017 Elsevier Inc. All rights reserved.

  20. Universality of revealed Law and reflections on religions in Medieval Islamic philosophy: a few considerations

    Full Text Available By analysing some Medieval Islamic philosophical theories, this paper aims at investigating the approach adopted by authors such as Avicenna and Averroës in respect of religions different from those of origin (Judaism, Christianism, Zoroastrianism and Sabeism. Moreover, it reflects on the universality of Islamic religion. The author will examine these philosophers' thoughts on prophetic teaching, recalling the Platonic sources from which they were developed, she will motivate the relevance of such thoughts in political science and she will explain their purposes. Furthermore, through a comparison with several scholars who have focused on whether Islamic Law has a conventional or natural status, she will try to investigate the origins of this problem, by examining the universal message that those Islamic Medieval philosophers found in revealed Law and the reasons that led them to present it as addressed to the whole mankind.

  1. The effect of fires on the development and appearance of medieval towns

    Directory of Open Access Journals (Sweden)

    Domen Kušar

    2003-01-01

    Full Text Available The occurrence of fires was one of the main dangers, which slowed down development of medieval towns. Frequent fires, whether they occurred due to carelessness, poorly maintained fireplaces and chimneys or military attacks, caused damage, particularly to those towns and buildings, which were constructed of inflammable materials such as timber and straw. In medieval times most towns were built using such materials, except those near the coast. Citizens tried to reduce fire hazards and the consequences of fires. With substitution of inflammable materials, apparatus and with the improved maintenance of fireplaces and chimneys, as well as other preventive measures, they influenced the development of towns and thus changed their architectural image.

  2. Transient Astronomical Events as Inspiration Sources of Medieval and Renaissance Art

    2011-06-01

    It is known long since that a number of exceptional and highly impressive astronomical events have been represented in Medieval artworks. We just remember the Bayeux Tapestry and Giotto's The Adoration of the Magi in the Scrovegni Chapel in Padua, representing the P/Halley comet transits of 1067 and 1301, respectively, while The Apparition of Star to Magi fresco in the San Pietro in Valle Abbey in Ferentillo (1182) has been suggested to represent the 1181 supernova. However, no systematic survey of figurative Medieval and Renaissance art has been performed to date, in order to analyzing the role of transient astronomical events as inspiration sources of artworks in these epochs. In this work, we analyze a significant number of artworks, dated between the 9th and 16th century and representing figurative elements in some way connected with astronomy, in order to evaluate if they have been influenced by coeval extraordinary astronomical events.

    This paper is a critique of Michael Postan's famous Malthusian-Ricardo model demonstrating that late-medieval prices and wages were essentially determined by demographic factors, especially after the Black Death, while contending that monetary factors played no role in determining prices or wages. His central argument is simple: that rapid and drastic depopulation (falling perhaps from ca. 1320) - by about 50% in England ca. 1450 - drastically altered the land:labour ratio so that real wages ...

  17. Reported weather events in medieval Hungary: the 11th-15th centuries

    Science.gov (United States)

    Kiss, Andrea

    2017-04-01

    In the presentation an overview of weather events, documented in contemporary written sources - available both in private and institutional evidence -, is provided: geographically the study covers the Hungarian kingdom (occasionally also with sources from the medieval Croatian kingdoms) that included most parts of the Carpathian Basin. Even if the temporal coverage extends the high and late medieval period between 1000 to 1500, most of the data comes from the late medieval times, with special emphasis on the 15th century. Most of the information is available regarding cold spells (e.g. early and late frosts), but especially cold winter periods. Nevertheless, contemporary documentary evidence - mainly legal documentation (charters), official and private correspondence, partly narratives and town accounts - also consists of evidence concerning other, weather-related extreme events such as (thunder)storms, floods and droughts. Apart from the discussion of the availability and type of these events, based on the relative frequency of occurrence we can define periods when a higher frequency and magnitude of weather-related events were reported that is mainly not dependent on changing source densities. These detectable periods (e.g. the early and mid-14th, early and late 15th centuries) are also a further, separate topic of discussion in the presentation.

    Peloponnese has been one of the cradles of the Classical European civilization and an important contributor to the ancient European history. It has also been the subject of a controversy about the ancestry of its population. In a theory hotly debated by scholars for over 170 years, the German historian Jacob Philipp Fallmerayer proposed that the medieval Peloponneseans were totally extinguished by Slavic and Avar invaders and replaced by Slavic settlers during the 6th century CE. Here we use 2.5 million single-nucleotide polymorphisms to investigate the genetic structure of Peloponnesean populations in a sample of 241 individuals originating from all districts of the peninsula and to examine predictions of the theory of replacement of the medieval Peloponneseans by Slavs. We find considerable heterogeneity of Peloponnesean populations exemplified by genetically distinct subpopulations and by gene flow gradients within Peloponnese. By principal component analysis (PCA) and ADMIXTURE analysis the Peloponneseans are clearly distinguishable from the populations of the Slavic homeland and are very similar to Sicilians and Italians. Using a novel method of quantitative analysis of ADMIXTURE output we find that the Slavic ancestry of Peloponnesean subpopulations ranges from 0.2 to 14.4%. Subpopulations considered by Fallmerayer to be Slavic tribes or to have Near Eastern origin, have no significant ancestry of either. This study rejects the theory of extinction of medieval Peloponneseans and illustrates how genetics can clarify important aspects of the history of a human population.

  19. Duration and severity of Medieval drought in the Lake Tahoe Basin

    Droughts in the western U.S. in the past 200 years are small compared to several megadroughts that occurred during Medieval times. We reconstruct duration and magnitude of extreme droughts in the northern Sierra Nevada from hydroclimatic conditions in Fallen Leaf Lake, California. Stands of submerged trees rooted in situ below the lake surface were imaged with sidescan sonar and radiocarbon analysis yields an age estimate of ∼1250 AD. Tree-ring records and submerged paleoshoreline geomorphology suggest a Medieval low-stand of Fallen Leaf Lake lasted more than 220 years. Over eighty more trees were found lying on the lake floor at various elevations above the paleoshoreline. Water-balance calculations suggest annual precipitation was less than 60% normal from late 10th century to early 13th century AD. Hence, the lake’s shoreline dropped 40–60 m below its modern elevation. Stands of pre-Medieval trees in this lake and in Lake Tahoe suggest the region experienced severe drought at least every 650–1150 years during the mid- and late-Holocene. These observations quantify paleo-precipitation and recurrence of prolonged drought in the northern Sierra Nevada.

  20. The "Endura" of The Cathars' Heresy: Medieval Concept of Ritual Euthanasia or Suicide?

    Science.gov (United States)

    Tsiamis, Costas; Tounta, Eleni; Poulakou-Rebelakou, Effie

    2016-02-01

    The aim of the study is to explore the medieval concepts on the voluntary death of severely sick people, as they emerge through the endura (endurance) of the heresy of the Cathars in France (twelfth to fourteenth centuries). The endura was the prerequisite act of repentance that would allow the fallen soul to return to heaven. The endura was a necessary act of repentance, after the performance of a ceremonial purification of the soul (consolamentum), and consisted of the patients' voluntary abstention from vital food. The consolamentum and endura could be performed in the final stage of a disease with the consent of the patients or their relatives. The role of the Cathar physician was only to determine the severity of the disease and the forthcoming death of the patient. The physician was not allowed to take steps that would deprive the life of the patient, and the performance of the ritual endura was duty of the spiritual leaders of the community. The modern ethical approach to this subject is dictated by the medieval belief on the salvation of the soul and tries to answer the question of whether the endura could be seen as a medieval concept of a ritual euthanasia or fell within the theological sin of suicide.

    To investigate the usefulness of humerus measurement for sex determination in a sample of medieval skeletons from the Eastern Adriatic Coast. Additional aim was to compare the results with contemporary female population. Five humerus measurements (maximum length, epicondylar width, maximum vertical diameter of the head, maximum and minimum diameter of the humerus at midshaft) for 80 male and 35 female medieval and 19 female contemporary humeri were recorded. Only sufficiently preserved skeletons and those with no obvious pathological or traumatic changes that could affect the measurements were included. For ten samples, analysis of DNA was performed in order to determine sex using amelogenin. The initial comparison of men and women indicated significant differences in all five measures (Pmedieval and contemporary women did not show significant difference in any of the measured features. Sex results obtained by anthropological and DNA analysis matched in all 10 cases. The results indicate that humerus measurement in Croatian medieval population may be sufficient to determine the sex of the skeleton. Furthermore, it seems that secular changes have not substantially affected contemporary population, suggesting that the results of this study are transferable to contemporary population as well.

    A new 2400-year paleoclimate reconstruction from Chesapeake Bay (CB) (eastern US) was compared to other paleoclimate records in the North Atlantic region to evaluate climate variability during the Medieval Climate Anomaly (MCA) and Little Ice Age (LIA). Using Mg/Ca ratios from ostracodes and oxygen isotopes from benthic foraminifera as proxies for temperature and precipitation-driven estuarine hydrography, results show that warmest temperatures in CB reached 16-17. ??C between 600 and 950. CE (Common Era), centuries before the classic European Medieval Warm Period (950-1100. CE) and peak warming in the Nordic Seas (1000-1400. CE). A series of centennial warm/cool cycles began about 1000. CE with temperature minima of ~. 8 to 9. ??C about 1150, 1350, and 1650-1800. CE, and intervening warm periods (14-15. ??C) centered at 1200, 1400, 1500 and 1600. CE. Precipitation variability in the eastern US included multiple dry intervals from 600 to 1200. CE, which contrasts with wet medieval conditions in the Caribbean. The eastern US experienced a wet LIA between 1650 and 1800. CE when the Caribbean was relatively dry. Comparison of the CB record with other records shows that the MCA and LIA were characterized by regionally asynchronous warming and complex spatial patterns of precipitation, possibly related to ocean-atmosphere processes. ?? 2010.

    Pearn, John

    2013-02-01

    The Montpellier physician Bernard de Gordon flourished in the late Middle Ages in the era when university education first evolved in the training of European physicians. Fragmentary details of his life and medical influence are known from seven books, particularly his extensive (163 chapters) text Lilium Medicine and from Chaucer's reference to him in the Canterbury Tales. Chaucer lists Bernard de Gordon as one whose writings were part of the core curriculum of the best-trained European doctors of medieval Europe. Bernard de Gordon was one of that small group of medieval physicians who reverently followed Galenic lore which had endured for a thousand years yet who began to challenge its details and to experiment clinically with new methods of treatment. In his writings, Bernard de Gordon made the first reference to spectacles and to the hernial truss. His writings also contained detailed desiderata for the ethical best practice of medicine of his day, extending the principles of both Hippocrates and Haly ibn Abbas. Unlike many of the surviving writings of other medieval medical teachers, his texts have within them a tone of humility and acknowledged fallibility. Bernard de Gordon holds a small but significant place in the evolving pre-Renaissance chronology of medical professionalism.

    Climatic variations in Canada during the Medieval Warm Period and the Little Ice Age are analysed from multidisciplinary and multiproxy data (tree ring growth, glacier movements, varved sediments, lake microfossils, early instrumental data, documentary and discursive sources). They are examined in parallel with the critical relationship between human and their environment, with the aim to give a better portrait of climatic changes from different perspectives, taking into consideration regional and seasonal disparities and show long-term climate anomaly (proxy-data) and weather-related extreme events (human archives). The preliminary results of the compilation suggest that, in Canada, the Medieval Warm Period and the Little Ice Age were initiated earlier in the Western part and expended to the East and North. The Medieval Warm Period was recorded from 700-1000 AD to 1100-1300 AD. It lasted longer in Southern Canada ( 400 years) than in Northern Canada ( 200 years). The Little Ice Age was recorded from 1150-1300 AD to 1850 AD. It was characterized by 2 or 3 cooling pulses of 50 to 200 years each occurring around 1400-1450, 1600-1650 and 1800-1850 AD. Most of the reconstructions agreed with an ending in 1850 AD, with exception of the Eastern part of Canada where cold conditions were recorded until the late 19th century. The Year Without a Summer (1816) was recorded in most regions. It was associated with the Tambora eruption and amplified by cold conditions in early-19th century.

  5. The Legal Regulation of Artisan and Trade Corporations in the Cities of Medieval Europe

    Full Text Available This article features an analysis of the legal regulation of the formation and activity of artisan and trade corporations in the cities of medieval Europe. Based on the findings of an analysis of existing scientific theories, as well as a study of legal and regulatory acts, the author aims to explore the issue of the emergence of cities and workshop organizations in them and reveal their legal essence and content. The relevance of this paper is due to the fact that up until now a sufficiently definitive opinion is yet to be propounded in historical and historical/legal science as to the origin and development of such specific urban institutions as workshops and workshop corporations, with their special legal regulation. The author comes to the conclusion that the formation of cities and workshop organizations reflected the evolution of the economic and social development of medieval society, which was associated with social division of labor. The paper’s major focus is not on the statutory regulation of the work of masters and not on the regulation of workshop craft methods, which can be explained quite logically by the economic need for adapting medieval artisan production to the limited needs and capacity of the local market, and which is the subject of study for the majority of present-day scholars, but issues related to the very organization of the workshop, its position in the system of urban establishments, as well as the legal status of its members.

    In this paper we present a model based on the principles of Linked Data that can be used to describe the interrelationships of images, texts and other resources to facilitate the interoperability of repositories of medieval manuscripts or other culturally important handwritten documents. The model is designed from a set of requirements derived from the real world use cases of some of the largest digitized medieval content holders, and instantiations of the model are intended as the input to collection-independent page turning and scholarly presentation interfaces. A canvas painting paradigm, such as in PDF and SVG, was selected based on the lack of a one to one correlation between image and page, and to fulfill complex requirements such as when the full text of a page is known, but only fragments of the physical object remain. The model is implemented using technologies such as OAI-ORE Aggregations and OAC Annotations, as the fundamental building blocks of emerging Linked Digital Libraries. The model and implementation are evaluated through prototypes of both content providing and consuming applications. Although the system was designed from requirements drawn from the medieval manuscript domain, it is applicable to any layout-oriented presentation of images of text.

Se subraya la importancia que el uso material de los animales tuvo a la hora de conformar esa actitud. En la segunda parte del trabajo se profundiza en manifestaciones como la simbología o la magia en donde los animales jugaron un papel principal. Un último punto del trabajo comenta la hipótesis de J. Salisbury sobre el descubrimiento, a partir del siglo xii, del animal interior presente en los hombres.The present paper reviews the role played by animals in medieval society and mentality. In particular we stress the importance which the material use of each species had in determining specific roles. The second part of the work deals with symbolic and magical connotations, fields in which animáis played a most prominent role throughout medieval times. One final aspect comments on J. Salisbury's hypothesis of «the beast within man» which seems to date back to the tweifth century.

  8. Alteration of medieval stained-glasses. Contribution to the long-term behaviour of vitrified wastes

    1998-01-01

    In this work, the behaviour of glasses during alteration have been studied in two different ways: 1)study of the alteration of medieval stained-glasses 2)experimental leaching of modelled glasses. Medieval stained-glasses have a silico-calcic and alkaline composition. It appears three different alteration modes for these glasses: 1)by condensation waters 2)by atmospheric agents 3)by porosity waters and humic acids. A chemical study of the altered areas has allowed to understand the alteration behaviour of a lot of elements: in particular transition elements, heavy metals and some rare earths. On the other hand, two vitrified wastes and a glass having the same composition of the potassic medieval stained-glasses have been leached in a static mode (pH=1 to 10, T=20 to 80 degrees Celsius, T=12 hours to 6 months). These experiments have revealed that the alteration mechanisms depend on the pH of the solution and on the chemical composition of the glass. An increasing durability of glasses in terms of the global polymerization degree has been revealed too. At last, the behaviours of glasses during alteration, observed with natural and experimental conditions, show that it is necessary to study natural analogous for predicting the long-term behaviour of vitrified wastes.

    Full Text Available Introduction: Irrigation of the root canal system is an important part of the endodontic treatment principle which aims to improve the hygiene of the root canal system from any debris and medicament residue with the hydrodynamic system. Root irrigation technique can be done with the manual and sonic system by using 2.5% NaOCI irrigation solution. Calcium hydroxide is used as a medicament for root canal sterilization. Root canal treatment will fail due to the imperfect removal of calcium hydroxide residue. The objective of this research was to analyze the comparison of the removal of calcium hydroxide medicaments on the root canal treatment irrigated with manual and sonic agitation technique using 2.5% sodium hypochlorite solution. Methods: The methods used in this study was experimental laboratory. The sample used was 30 maxillary incisors. The teeth were then divided into two groups randomly, then the root canal preparation was done by the crown down technique with manual irrigation using 2.5% NaOCI solution. The radicular part of the teeth was then split longitudinally, given a standardized groove in the one-third of the apical part, then applied with water-solved calcium hydroxide. The teeth were unified afterwards by using flowable composites, then soaked in the artificial saliva at the temperature of 37ºC. The sample of the 1st group was irrigated by manual agitation technique, and the sample of the 2nd group 2 was irrigated by sonic agitation technique, then both were viewed by stereo microscope. The data results were analyzed by Kruskal-Wallis and Mann-Whitney tests. Results: The results of calcium hydroxide removal were different between the root canals that were irrigated using 2.5% sodium hypochlorite irrigation solution by manual agitation technique compared to the sonic agitation technique. Irrigation using 2.5% sodium hypochlorite irrigation solution with the sonic agitation techniques were proven to be more effective in lifting Ca

The root canals of 102 maxillary incisors were enlarged to simulate immature roots and were randomly divided into three groups (n = 34: a control group (no intracanal medicament and two test groups, subjected to calcium hydroxide (CH or triple antibiotic paste (TAP medication for two weeks. After the medication removal, each group was divided in two subgroups and the coronal portion of each canal was filled with MTA or BD. After one week of storage, the coronal region of each root was horizontally sectioned and push-out test was performed. Data were analyzed by two-way analysis of variance and the Tukey post hoc test (P = 0.05. PBS values were significantly affected by the type of material (P < 0.001 and the type of medication used (P = 0.049, but no interaction was found (P = 0.97. The BD group showed significantly higher push-out resistance values than those of the MTA group (P < 0.001. TAP showed the lowest PBS values, which were significantly lower than those of the control group (P = 0.043 but not than those of CH (P = 0.229. After a two-week application period, TAP seemed to decrease the PBS of both cements, while CH did not. BD appeared to have higher PBS compared to MTA, regardless of medication.

Se hizo uso de una encuesta realizada por el CIS (2005; estudio n.º 2590 sobre una muestra representativa de la población española formada por 2.490 participantes. Los resultados muestran que las personas cuya frecuencia de comportamientos proambientales resultó ser moderada mostraron una clara tendencia a atribuir a los españoles esa misma frecuencia en su comportamiento pro-ambiental. Sin embargo, aquellos cuyo comportamiento pro-ambiental resultó ser más extremo, debido a una alta frecuencia de conductas pro-ambientales, mostraron una tendencia a atribuir un comportamiento distinto del suyo. Estas personas se consideraron como diferentes del resto de la población. Además, se encontró que las diferencias en la percepción social del comportamiento de los españoles en materia medioambiental están asociadas con percepciones diferentes del deterioro ambiental y de la preocupación hacia el medio ambiente.

  11. Charlemagne's summit canal: an early medieval hydro-engineering project for passing the Central European Watershed.

    Directory of Open Access Journals (Sweden)

    Christoph Zielhofer

    Full Text Available The Central European Watershed divides the Rhine-Main catchment and the Danube catchment. In the Early Medieval period, when ships were important means of transportation, Charlemagne decided to link both catchments by the construction of a canal connecting the Schwabian Rezat and the Altmühl rivers. The artificial waterway would provide a continuous inland navigation route from the North Sea to the Black Sea. The shortcut is known as Fossa Carolina and represents one of the most important Early Medieval engineering achievements in Europe. Despite the important geostrategic relevance of the construction it is not clarified whether the canal was actually used as a navigation waterway. We present new geophysical data and in situ findings from the trench fills that prove for the first time a total length of the constructed Carolingian canal of at least 2300 metres. We have evidence for a conceptual width of the artificial water course between 5 and 6 metres and a water depth of at least 60 to 80 cm. This allows a crossing way passage of Carolingian cargo scows with a payload of several tons. There is strong evidence for clayey to silty layers in the trench fills which reveal suspension load limited stillwater deposition and, therefore, the evidence of former Carolingian and post-Carolingian ponds. These findings are strongly supported by numerous sapropel layers within the trench fills. Our results presented in this study indicate an extraordinarily advanced construction level of the known course of the canal. Here, the excavated levels of Carolingian trench bottoms were generally sufficient for the efficient construction of stepped ponds and prove a final concept for a summit canal. We have evidence for the artificial Carolingian dislocation of the watershed and assume a sophisticated Early Medieval hydrological engineering concept for supplying the summit of the canal with adequate water.

  12. The Fingerprint of Persistence: The Remarkable Character of Medieval Climate Change over the Western US

    Science.gov (United States)

    Graham, N. E.; Hughes, M. K.

    2007-12-01

    The body of evidence for persistent aridity and recurrent severe drought across the western US during Medieval times (more or less 800-1300 AD) has grown from suggestive tree-ring chronologies developed during 1970s to a variety of convincing proxy records available today. These records come from tree-rings (moisture availability), lake level reconstructions (precipitation), sediment charcoal and fire scar records (wild fire), pollen and diatom assemblages (moisture availability, river discharge), soil mobilization (rainfall, wind) and archeological studies. Two recurring themes that arise from this collected work are that a) the instrumental climate record for the West is not representative of the past millennium, and b) Medieval climate in the West was marked more by persistent precipitation deficits than by remarkably dry years. Such change requires persistently altered circulation patterns which, in turn, imply important and long-lasting changes in boundary conditions. Recent proxy-model statistical studies and dynamical model experiments have attempted to reconstruct circulation changes and mechanisms that may have produced these precipitation changes. Not surprisingly, the results are consistent with the idea that Medieval climate change over the western US resulted from persistently cool sea surface temperatures in the eastern tropical Pacific. Notably, such cooling is supported by proxy records from the tropical and mid-latitude Pacific. While this congruence of proxy and model results is not conclusive, alternative candidates for producing such circulation changes have not yet been put forward and tested. The presentation will review the much of evidence discussed above and frame a general picture of current hypotheses.

    The Central European Watershed divides the Rhine-Main catchment and the Danube catchment. In the Early Medieval period, when ships were important means of transportation, Charlemagne decided to link both catchments by the construction of a canal connecting the Schwabian Rezat and the Altmühl rivers. The artificial waterway would provide a continuous inland navigation route from the North Sea to the Black Sea. The shortcut is known as Fossa Carolina and represents one of the most important Early Medieval engineering achievements in Europe. Despite the important geostrategic relevance of the construction it is not clarified whether the canal was actually used as a navigation waterway. We present new geophysical data and in situ findings from the trench fills that prove for the first time a total length of the constructed Carolingian canal of at least 2300 metres. We have evidence for a conceptual width of the artificial water course between 5 and 6 metres and a water depth of at least 60 to 80 cm. This allows a crossing way passage of Carolingian cargo scows with a payload of several tons. There is strong evidence for clayey to silty layers in the trench fills which reveal suspension load limited stillwater deposition and, therefore, the evidence of former Carolingian and post-Carolingian ponds. These findings are strongly supported by numerous sapropel layers within the trench fills. Our results presented in this study indicate an extraordinarily advanced construction level of the known course of the canal. Here, the excavated levels of Carolingian trench bottoms were generally sufficient for the efficient construction of stepped ponds and prove a final concept for a summit canal. We have evidence for the artificial Carolingian dislocation of the watershed and assume a sophisticated Early Medieval hydrological engineering concept for supplying the summit of the canal with adequate water.

    Widely distributed proxy records indicate that the Medieval Climate Anomaly (MCA; {proportional_to}900-1350 AD) was characterized by coherent shifts in large-scale Northern Hemisphere atmospheric circulation patterns. Although cooler sea surface temperatures in the central and eastern equatorial Pacific can explain some aspects of medieval circulation changes, they are not sufficient to account for other notable features, including widespread aridity through the Eurasian sub-tropics, stronger winter westerlies across the North Atlantic and Western Europe, and shifts in monsoon rainfall patterns across Africa and South Asia. We present results from a full-physics coupled climate model showing that a slight warming of the tropical Indian and western Pacific Oceans relative to the other tropical ocean basins can induce a broad range of the medieval circulation and climate changes indicated by proxy data, including many of those not explained by a cooler tropical Pacific alone. Important aspects of the results resemble those from previous simulations examining the climatic response to the rapid Indian Ocean warming during the late twentieth century, and to results from climate warming simulations - especially in indicating an expansion of the Northern Hemisphere Hadley circulation. Notably, the pattern of tropical Indo-Pacific sea surface temperature (SST) change responsible for producing the proxy-model similarity in our results agrees well with MCA-LIA SST differences obtained in a recent proxy-based climate field reconstruction. Though much remains unclear, our results indicate that the MCA was characterized by an enhanced zonal Indo-Pacific SST gradient with resulting changes in Northern Hemisphere tropical and extra-tropical circulation patterns and hydroclimate regimes, linkages that may explain the coherent regional climate shifts indicated by proxy records from across the planet. The findings provide new perspectives on the nature and possible causes of the MCA

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

    The workshop will focus on climatic variations during the Medieval Warm Period or Little Climatic Optimum. The nominal time interval assigned to this period is AD 900--1300, but climate information available during the century or two preceding and following this episode is welcome. The aims of the workshop will be to: examine the available evidence for the existence of this episode; assess the spatial and temporal synchronicity of the climatic signals; discuss possible forcing mechanisms; and identify areas and paleoenvironmental records where additional research efforts are needed to improve our knowledge of this period. This document consists of abstracts of eighteen papers presented at the meeting.

    The Ebstorf Map (Wilke, 2001; Kugler, 2007; Wolf, 2004, 2006, 2007, 2009a, b), the largest medieval map of the world whose original has been lost, is not only a geographical map. In the Middle Ages, a map contained mystic, historical and religious motifs. Of central importance is Jesus Christ, who, in the Ebstorf Map, is part of the earth. The Ebstorf Map contains the knowledge of the time of its creation; it can be used for example as an atlas, as a chronicle of the world, or as an illustrated Bible.

    Baolis es el depósito de agua en los monumentos arquitectónicos que habían sido construidos por varios sultanato de Delhi en diferentes períodos de tiempo y la mayoría de Baolis fueron construidos durante el período de tiempo medieval. Los Baolis se encuentran en todo el país, pero todos son diferentes en lo que respecta al arte y la arquitectura. Los sultanatos de Delhi habían construido una serie de Baolis en Delhi para mostrar su control y prestigio en la sociedad. Hay alrededor de 12 Baolis existentes en Delhi y de ellos, cuatro Baolis están a punto de extinguirse y pocos Baolis como Nizamuddin, Firoz Shah y Rajon ki Baolis están siendo utilizados por la gente local. Este artículo comprende la información relacionada con Baolis que fue construida por sultanatos de Delhi durante el período de tiempo medieval en Delhi. El presente trabajo intenta describir el método tradicional de gestión del agua como Baolis en época medieval y su estado actual. El estudio se basa en fuentes primarias y secundarias de información y se realizó una encuesta primaria y personal y se han utilizado fuentes secundarias de datos e información en este documento. El artículo concluyó que Baolis no está teniendo buenas condiciones y estas están muy contaminadas y degradadas y su degradación también conduce a la pérdida ecológica hidrológica en sus áreas adyacentes. Los acercamientos descuidados de la gente hacia estos Baolis son causas principales detrás de la extinción y de la degradación de estos Baolis. La conciencia de la comunidad y la participación es la única manera de proteger a estos Baolis de la extinción.

    Full Text Available Mineralogical and petrographic studies of Early Medieval potshards exhumed in the Viile Tecii archaeological site (North Transylvania, Romania show a ceramic body composed of a microcrystalline to amorphous matrix, various clasts and voids. The microscopical features and XRD patterns indicate that illitic-kaolinitic clays were used as raw materials, together with quartzitic sands as tempering material. The ceramic vessels were obtained with the potter’s wheel, but the fabric is only slightly oriented, due either to the fast modeling or to the coarseness of the clayish paste. The thermal alteration of mineral phases points to relatively high firing-temperatures, between 800 and 900°C.

    Experimental analyses have been carried out on tuff masonry specimens in order to investigate the structural behaviour of historical buildings in the Naples area (Southern Italy). Spandrels of post-medieval buildings (late XVI to early XX century) have been analysed, with emphasis on morphological characteristics according to chronological indicators. Results of the experimentation on scaled models (1:10) are discussed and the better behaviour of historical masonry typologies on respect to the modern one is highlighted. Comparison with theoretical formulations of ultimate shear resistance are provided too
