    2010-01-01

    This paper explores the links between scientific practice and precision both in expert networks and popular literature in the second half 18th century Spain. It will be argued that scientific instruments were used and understood in different ways in these two networks, which required opposing strategies for visualizing the degree and goodness of users' dexterities, thereby fostering the emergence of different collective and individual (epistemic) subjects. I will also argue that these subjects' differences and affinities were constructed around three themes: firstly, the degree of precision needed to establish a correlation between data and the world, or, in other words, the degree of fluidity admitted in connecting material and cultural worlds; secondly, the relevance attributed to body and bod(il)y knowledge in producing reliable data and stabilizing expertise; and thirdly, the weight attributed to opinion in leaning towards ephemeral or lasting data. The first part of the paper looks at the epistemological and political confluences which in late 18th century Spain nurtured the emergence of both a culture of precision and a sphere of public opinion, and to the strained relationship that existed between them. The other three sections explore how Spanish people used different sets of practices to construct different images of themselves as supporters of a moral of precision.

    We present a new catalogue of observations of the aurora borealis at Lisbon, i.e., at low-latitudes, in the late 18th century by Jacob Præ torius and Henrique Schulze, two German artillery officers. Dates of 18 auroras compiled by Præ torius and Schulze are compared with those published in other catalogues for that period. The number of annual auroras observed by the two Germans is then compared with two indices of solar activity showing a very good level of consistency between all time series. Finally, we have assessed the number of auroras observed taking into consideration the phase of the lunar cycle and the geomagnetic latitude of Lisbon.

    From the time they established their first shelter among the Inuit population of the northern coast of Labrador in 1771, the brethren of the Moravian Church began producing series of daily instrumental and qualitative meteorological observations of significance to science networks of the day (Macpherson, 1987, Demarée & Ogilvie, 2008). Contrary to what is understood, missionaries did not make these observations for their own purposes. Rather, they responded to requests from scientists who commissioned the data. Scientists also equipped these undertakings. The enlightened observers provided handwritten copies that were publicized in England and continental Europe by individuals and their philosophical and scientific institutions. This pattern of producing reliable records specifically for scientists was true for the 15-year span of Moravian meteorological observations for all 3 Labrador stations in the late 18th century; the 40-year span of records for 10 Moravian stations in Labrador and Greenland in the mid-19th century; and the observations from 5 Labrador stations commissioned for the 1st international Polar Year, 1882, and continuing for several decades afterward, and longer in the case of Nain. When Nain data is combined with that from the Canadian meteorological service, we have a relatively straight run from 1882 to 2015. In this paper, we examine the late-18th century Moravian meteorological observations for qualitative information of interest to modern scientific research. The daily entries comprise not only measurements of temperature and air pressure, but also other weather observations, such as wind direction, estimated wind speed, cloudiness, information which has already allowed us to begin tracking polar lows travelling from Labrador to Greenland across the Labrador Sea. The annual missionary reports of Moravians provide critical supplementary data identifying recurring local phenological events in nature, which offer an integrated signal of weather

    We investigated the time data in Chinese astronomical almanacs of the late 18th century in order to estimate the accuracy of the Shixian calendar. It is known that the calendar was enforced during the period of the Ching dynasty (1664--1912), and several astronomical almanacs using the calendar are preserved in the Kyujanggak Institute for Korean Studies of Korea; these almanacs cover the years 1772, 1773, 1774, 1780, 1781, 1783, 1785, and 1787. We compiled the times of the new moon, sunrise/sunset, and twenty-four seasonal subdivisions from the almanacs and compared them with the results of modern calculations. As a result, we found that the times of the new moon and twenty-four seasonal subdivisions show average differences of ˜ 3.35 ± 4.43 and ˜ 9.67± 13.24 min, respectively. Regarding he sunrise/sunset time, however, we found that the difference was less than 1 min when we defined the time as the moment that the zenith distance (z) of the Sun is 90°, unlike the modern definition, z=90° 50'. We expect that this study to contribute to the understanding of the accuracy obtained by Shixian calendar in calculations of the movements of celestial bodies.

  5. Climate and history in the late 18th and early 19th centuries

    NASA Astrophysics Data System (ADS)

    Feldman, Theodore S.

    As in many areas of human knowledge, the notion of climate acquired a deeper historical content around the turn of the 19th century. Natural philosophers, geographers, and others became increasingly aware of climate's own history and its relation to human, plant and animal, and Earth history. This article examines several aspects of this “historicization” of climate.The lively 18th century discussion of the influence of climate on society is well known. Montesquieu is its most famous representative, but Voltaire, Hume, Kant, and others also participated. Their debate was literary more than scientific, their goal the understanding of man, not climate. Partly for this reason and partly because of the lack of good information on climates, they made no attempt to gather substantial climatic data. In fact, the importance of systematically collecting reliable data was scarcely understood in any area of natural philosophy before the last decades of the century [Cf. Frängsmyr et al., 1990; Feldman, 1990]. Instead, participants in the debate repeated commonplaces dating from Aristotle and Hippocrates and based their conclusions on unreliable reports from travelers. As Glacken wrote of Montesquieu, “his dishes are from old and well-tested recipes” [Glacken, 1967, chapter 12]. This is not to say that the debate over climatic influence was not significant—only that its significance lay more in the history of man than in the atmospheric sciences.

    Two mummies of the Hungarian mummy collection from Vác were the subjects of anthropological, paleopathological, radiological, paleomicrobiological, paleohistological and paleoproteomic studies. Both individuals belonged to the same family. The father, József Nigrovits (No 29), died at the age of 55 on the 11th of November 1793; his son, Antal Nigrovits (No 54), died on the 16th of July 1803, at the age of 22. They lived in the 18th century in Vác, a small town in northern Hungary. The macroscopic examination of the son showed a severely deformed neck and back region; the father has no visible mark of any illnesses. As earlier researches showed that tuberculosis was widespread in the community, the etiology of these deformities was examined. The paleomicrobiological results found that both individuals were infected with tuberculosis. Although they suffered from TB, the CT scan data of the bodies and their 3D reconstructions showed no skeletal evidence of tuberculosis. The deformity of the son turned to be a developmental abnormality of unknown origin, but no Pott's gibbus was present. Copyright © 2015 Elsevier Ltd. All rights reserved.

    The aim of this study is to elaborate comparative portraits of Korean and Japanese beauty in the late 18th and early 19th centuries. Six portraits of beauty in the Korean Joseon Dynasty (early 19th century) and 5 in Japanese Edo Dynasty (late 18th century) were analyzed. Twenty anthropometric items were applied to the measure of the features on each portrait and 18 proportional indices of the face were calculated. Among the 18 indices, Korean and Japanese beauty did not show any significant differences in 13, but in 5: 1) the ratio of eye fissure to intercanthal distance was greater in Japanese beauty; 2) eye inclination was greater in Japanese beauty; 3) the ratio of nasal width to intercanthal distance was greater in Japanese beauty; 4) the ratio of nasal and facial width was greater in Korean beauty; and 5) the ratio of vermilion size to mouth width was greater in Japanese beauty. It is assumed that Korean had narrower eye fissure, lower eye inclination, wider nasal ala, and thinner lip than what Japanese craved during that era.

    The evaluation of patients' vital statistics is part of health care and in many cases this is the first step in knowing what is the health status of a patient. Therefore, we are interested in analysing what knowledge nurses had regarding these vital statistics during the 18th century, how they evaluated these statistics and what treatment they applied in order to maintain or balance them whenever they became unstable. A manual written by a nurse in the 18th century in order to aid her colleagues in their treatment of patients is the source of the authors' research material.

  9. Towards a daily weather type classification for the alpine region back to the late 18th century

    Synoptic weather type classifications for the alpine region go back to the 1950s. The aim of such a combination of various meteorological elements over a certain area is to better understand atmospheric circulation and weather events and to provide a basis for long-term weather forecasts. For the analyses of climate change an investigation of a change in the atmospheric circulation patterns is of high interest. Such a classification is based on high temporal resolution (subdaily) meteorological information on different parameters. For Switzerland, three long (~250 yrs) historical time series (Basel, Geneva, Gr. St. Bernhard) that were hitherto available in the form of monthly means only have recently been digitized (in cooperation with MeteoSwiss) on a subdaily scale. The digitized time series contain subdaily data (varies from 2-6 daily measurements) on temperature, precipitation/snow height, pressure and humidity, and subdaily descriptions on wind direction, wind speeds and cloud cover. Based on different combinations of the parameters pressure, wind direction and wind speed, a weather type classification can be performed back to the late 18th century. With information on absolute pressure height, tendencies and gradients, as well as changes in wind direction and wind speed, typical circulation patterns can be expressed and subsequently weather types for the alpine region classified. For Switzerland Schüepp's "Alpenwetterstatistik", which is often used for daily weather type classification in the alpine region, contains daily assignments to weather types for the last 50 years. With a probabilistic approach daily weather types can be assigned, based on centralized weather types of the "Alpenwetterstatistik". For the analysis of temperature and precipitation anomalies of the year without a summer (1816) in Switzerland, such weather type classifications based on pressure and wind were already conducted and applied.

    Thousands of ballistic blocks occur around Kīlauea Caldera and record part of the latest major period of explosive activity on the volcano, in late 1790 or within a few years thereafter. The sizes of the blocks – the largest of which is more than 2 m in nominal diameter – and differences in rock types allow the definition of at least 6 dispersal lobes of mostly undetermined relative age. The orientations of the lobes help approximate the locations of vents or explosion sources on the floor of the caldera, now deeply buried by younger lava flows. The vents may have been distributed northward for about 2 km from near the site of the modern Halema'uma'u Crater and were apparently confined to the western half of the caldera. The blocks are entirely lithic except for those in one dispersal lobe, which contains cored bombs and blocks as well as juvenile lapilli. Eruption parameters calculated from EJECT! suggest that the phreatic and phreatomagmatic explosions could have been generated at the water table, about 600 m below the high point on the caldera rim.

    2016-04-01

    This article aims to investigate the shaping of knowledge and discourse on ginseng, especially among physicians and botanists, since its introduction to France from the 17th century until the early 18th century. In France, knowledge on herbal medicine, including that of ginseng, was shaped under the influence of the modern state's policy and institution: mercantilism and the Académie royale des sciences. The knowledge of herbal medicine developed as an important part of the mercantilist policy supported systematically by the Académie. The East Asian ginseng, renowned as a panacea, was first introduced into France in the 17th century, initially in a roundabout way through transportation and English and Dutch publications of travel tales from various foreign countries. The publication activity was mainly conducted by Thévenot company with the intention to meet the needs of French mercantilism promoted by Colbert. It also implied interests on medicine in order to bolster the people's health. The Thévenot company's activity thus offered vital information on plants and herbs abroad, one of which was ginseng. Furthermore, with Louis XIV's dispatching of the Jesuit missionaries to East Asia, the Frenchmen were able to directly gather information on ginseng. These information became a basis for research of the Académie. In the Académie, founded in 1666 by Colbert, the king's physicians and botanists systematically and collectively studied on exotic plants and medical herbs including ginseng. They were also key figures of the Jardin du Roi. These institutions bore a striking contrast to the faculty of medicine at the University of Paris which has been a center of the traditional Galenic medicine. The research of the Académie on ginseng was greatly advanced, owing much to the reports and samples sent from China and Canada by Jartoux, Sarrazin, and Lapitau. From the early 18th century, the conservative attitude of the University of Paris, which was a stronghold of

    In the 18th century, numerous diseases with symptoms of oral cavity were cured by chirurgien-dentist, barber-surgeons, or tooth drawer. The so called "dentitio difficilis" was blamed for the high children mortality, therefore gum cut or use of leeches was advised as a treatment. Both acute and chronic type of gum inflammation was called scurvy. It seems that the mechanical removal of plaque was enough to cure the scurvy as it was written in advertisements from that time. Syphilis was present in the everyday life throughout centuries, and assumed to cause different stigmas in the oral cavity. Today we consider theses stigmas as the toxic signs of mercury treatment.

    2016-05-01

    As early as 1783, the almost forgotten philosopher, metaphysicist, and psychologist Ferdinand Ueberwasser (1752-1812) designated himself "Professor für empirische Psychologie und Logik" (professor of empirical psychology and logic) at the University of Münster, Germany. His position was initiated and supported by the minister and educational reformer Franz von Fürstenberg (1729-1810), who considered psychology a core scientific discipline that should be taught at each school and university. At the end of the 18th century, then, psychology seems to have been on the verge of becoming an independent academic discipline, about 100 years before Wilhelm Wundt founded the discipline's first official laboratory. It seems surprising that Ueberwasser's writings-including a seminal textbook on empirical psychology-have been almost entirely overlooked in most historical accounts. We focus on this important founding moment of psychological science and on the circumstances that eventually brought this seminal development to a halt.

    2010-01-01

    This overview reflects the extensive changes in the health care system which had significant effects on the apothecary’s profession and education. In the 18th century Maria Theresia assigned Gerard van Swieten to modernize the medical curriculum and to work out reforms for health care. The resulting sanitary bill released in 1770 and amended in 1773 became effective for the whole empire and influenced greatly the apothecary’s profession. The Viennese Medical Faculty continued to be the supervisory body for the apothecaries, a situation which prolonged the conflicts between the faculty and the apothecaries. The financial and social distress prevalent in the 19th century also affected the apothecary business and led to a crisis of the profession. Furthermore, the apothecaries’ missing influence over the sanitary authorities delayed the release of a badly needed new apothecary bill until 1906. The introduction of a specific pharmaceutical curriculum at the university in 1853 was a great step forward to improve the pharmaceutical education. Nevertheless, the secondary school exam was not compulsory for the studies until 1920 and, therefore, the graduates were not on a par with other university graduates before that date. Women, except nuns, were not allowed to work as pharmacists until 1900. PMID:21179353

    The paper presents the history of measurements of the geomagnetic field parameters over the territory of Russia in the 18th century derived from archival and literature sources. Topographical mapping of the European territory and neighboring seas of the Russian Empire from the late 17th to the mid 18th century during which magnetic measurements were made was of great importance for determining magnetic declination. The magnetic declination in Siberia and its neighboring seas was measured for the first time during the first expedition of V. Bering in 1728 and then during his second expedition (the Great Northern Expedition) in 1733-1742. Magnetic measurements were carried out along the northern coast of Siberia and in the Bering Sea. The academic group of the expedition performed magnetic declination measurements over southern regions of Siberia (Krasnoyarsk, Irkutsk, Nerchinsk, Yakutsk, etc.) in 1735 and 1736. During the second half of the 18th century, Russian expeditions determined geographical coordinates of the cities of European Russia and carried out magnetic declination measurements for them. During these expeditions Inokhodtsev paid attention to the anomalous magnetic declination in the Kursk region. In his opinion, the anomaly could have been caused by the presence of iron ore.

    The 18th-century Mongol astronomer Mingantu (1692-1765) has been honored with a city named after him and a nearby solar telescope array. During the IAU/Beijing, my wife and I went to the new Chinese solar radioheliograph, the Mingantu Observing Station, in Inner Mongolia, ~400 km northwest of Beijing, a project of the National Astronomical Observatories, Chinese Academy of Sciences. It currently contains 40 dishes each 4.5 m across, with a correlator from Beijing. Within a year, 60 2-m dishes will be added. We passed by the 12-century ruins of Xanadu (about 20 km north of Zhangbei) about halfway. The radioheliograph is in a plane about 1 km across, forming a three-armed spiral for interferometric solar mapping, something colleagues and I had carried out with the Jansky Very Large Array, taking advantage of the lunar occultation before annularity at the 20 May 2012 solar eclipse. In the central square of Mingantu city, a statue ~10-m high of the Mongol astronomer Mingantu appears. Its base bears a plaque ~1-m high of IAU Minor Planet Circular MPC 45750 announcing the naming in 2002 of asteroid 28242 Mingantu, discovered at a Chinese observatory in 1999. Mingantu carried out orbital calculations, mapping, mathematical work on infinite series, and other scientific research. He is honored by a modern museum behind the statue. The museum's first 40% describes Mingantu and his work, and is followed by some artifacts of the region from thousands of years ago. The final, large room contains a two-meter-square scale model of the radioheliograph, flat-screen televisions running Solar Dynamics Observatory and other contemporary visualizations, orreries and other objects, and large transparencies of NASA and other astronomical imagery.

However, at the same time, the mechanical materialism was also infiltrated into western clinical medicine.

    In the late 18th century two medical fashions--Mesmerism in France and the Perkins 'tractor' in the USA and England--appealed to the principle that a single universal force acts on all of us and is responsible for health and illness. This principle served both fashions well, as it made it all the easier for those who came within their force fields to experience the sort of sensations that other subscribers to the fashion also seemed to feel. The first research on what is now known as the placebo effect was in connection with these two movements. The propensity to feel what we suppose or imagine that others like us feel remains even now one of the channels of the placebo effect.

    Phthisis (tuberculosis) became so prevalent in Europe in the 18th century that, in 1792, Antoine Portal wrote: "there is no disease more common or dangerous than pulmonary phthisis." Obviously, the doctors were concerned about this problem and made efforts to explain it. Numerous hypotheses were advanced on this subject (Richard Morton, for instance, suggested 12 possible causes in his Phthisiologia), and varied by author and region, but they can be grouped into four main categories: a contagious disease; a hereditary condition; a physiological disorder; and a problem resulting from lifestyle. This research concerns the books on this disease procured by medical practitioners in and around Quebec City in the 18th and 19th centuries, dating from 1700-1868, and contained in 27 medical libraries. Following a brief presentation of methodology and the libraries, this article analyzes the books. There were books on phthisis in Quebec City very early in the 18th century, although the majority appeared in the next century. The 18th-century works associated this disease with physiological disorders--particularly "mechanical problems." After 1815, there was a broader diversity of opinions. The books on phthisis most widely consulted from 1700 to 1868 are almost completely unknown today.

    Only selected aspects of the history of the House of the Poor Insane in the Hanseatic Free City of Lübeck have been studied to date.This article presents the results of an entire source study of this small institution in the 17th and 18th centuries, and briefly also during the next 40 years after the opening of a new building. In addition to the minute-book of the Governors, now kept in the Lübeck Municipal Archives, the results are based primarily on the account-books,which illustrate the institution's social history and activities. Examples are given. During most of the 17th century, the House was generally rather like a prison for the insane, but at the end of this century and in the early 18th there was a reform phase.This was followed by phases of repression and 'containment' at the end of the 18th century and in the early 19th century, before a renewed reform by the medical profession.The findings for Lübeck are compared with the development of inpatient care in institutions elsewhere, and the decisive factors in Lübeck are discussed.

    "Longitudinal residential histories are used to examine the extent to which three rural areas in Britain had distinctive migration histories from the 18th to the 20th centuries. Migration flows into and out of the regions are used to examine the extent to which the regions were integrated into the British migration system, and the relative importance of rural to urban migration is assessed.... Analysis reveals a high degree of short-distance mobility within regions and emphasises the dominance of London in longer-distance migration.... It is also suggested that the role of towns in the migration system has previously been overemphasised, with much migration taking place between small settlements and some movement from large cities to smaller towns and villages.... The analysis challenges some accepted notions about migration in the past, and contributes to the debate about the extent to which British regions became part of a national economic and social system from the 18th century."

    The many changes in the etiopathogenic theories of hysteria, developed from the end of the 18th century to the end of World War I, can only be understood by studying the social, political, economic, and cultural transformations of the Western world during the same period. These transformations, presented below along with concurrent medical discoveries, make it possible to explain the ongoing metamorphosis of both hysteria and the image of the hysteric patient.

  13. The historical archaeology of the 17th- and 18th-century Jewish community of Nevis, British West Indies

    This is an historical archaeological examination of a 17th- and 18th-century Jewish community on the island of Nevis in the British West Indies. Unlike earlier archaeological studies of the Jewish Caribbean Diaspora that focused on single sites, this investigation used a community-wide approach to elucidate the daily experience of Sephardic Jews within the colonial Caribbean. This project included an archaeological excavation at the purported location of the community's synagogue, an electrical resistivity survey of the surviving cemetery, the construction of a map of property ownership in 18th-century Charlestown, and archival research. This study was carded out within a multiscalar and contextual framework that emphasized the importance of understanding the diaspora that brought the Jews to the West Indies, the development of the colonial Caribbean, and the surrounding environs of the port city of Charlestown, Nevis. The archaeological analysis of the supposed site of the synagogue proved that it was in fact that of a late 18th-century townhouse, but the associated land record research revealed the actual location of the community's former synagogue. Furthermore, the reconstruction of the physical layout of colonial-period Charlestown from the land records indicated the presence of a distinct Jewish quarter in the undesirable southern portion of the town. Evidence from the public records of Nevis and the social history of the members of the Jewish population unveiled external social and political pressures placed upon the Sephardim as well as internal religious and ethnic ties dig bound the community together. It is argued in closing that the archival evidence, in conjunction with the continued presence of a clustered settlement pattern like that of European Jewish communities during the medieval period, indicates that the Jews of the Caribbean were not fully integrated socially or politically into British colonial society.

    It has only recently been recognised that for more than a century before the opening of Great Ormond Street Hospital for Children (1852) children were treated and even admitted in English Voluntary Hospitals. Among the earliest English 18th century records, that contain the patient's age, are those found at the Northampton General Hospital within an archive dating from its foundation as the Northampton Infirmary in 1744. They afford a fascinating glimpse into both inpatient and outpatient child health. Although there are no medical notes as such, the hospital archive has recently rediscovered 1743 statutes, contemporary patient literature entitled Some Friendly Advice to a Patient (written by the Northampton Infirmary's founding physician Dr (later Sir) James Stonhouse), minute books, contemporary engravings of the outside and inside of the hospital and inpatient menus. Thus we can speculate with a high degree of certainty as to what would be the then current infirmary environment and treatments for illustrative examples of the children seen in the period 1744-45 (two inpatients and two outpatients). Interestingly one of the inpatient cases, Elizabeth Ager, a child with fever, was admitted against the infirmary regulations, suggesting already a stretching of boundaries in favour of paediatric admissions. This paper gives a flavour of 18th century hospital child healthcare in an era before the formal recognition of paediatrics as a medical specialty and preceding by more than a century the construction of specialist provision through the foundation of the first children's hospitals.

    Starting in the 1630s, in French towns, the rise of sermons gave an increasing group of clerics the possibility to become preachers. This article analyses this process of professionalization. First, it takes a look at a number of long - and sometimes quite profitable - careers of men as preachers. Second, it analyzes the know-how that was then developed for to make and recite the sermon. Finally, the article focuses on the transformations brought about by the increasing importance of written communication during the 18(th) century.

    18th-century discussions on the generation of imperfect plants were often linked with the question of their position in the natural world, namely as whether they were part of the vegetable or mineral realm. As attested by the work of Joseph Gaertner, Johann Jakob Dillen, Pier Antonio Micheli and René-Antoine Ferchault de Réaumur, as well as of Antonio Vallisneri, and Lazzaro Spallanzani, the different images of nature - continuity and discontinuity - adopted by naturalists influenced their solution to this question.

    The nucleus of this work is the wide spectrum of means available to the inhabitants of the city of Alicante in the 18th century to fight against disease. Alongside healthcare professionals properly trained as physicians, surgeons, barbers or midwives, there were both other healers of heterogeneous types and religious resources. The study considers, in a comprehensive and articulated way, the whole repertoire of therapeutic and healthcare alternatives provided to the inhabitants of Alicante. The interpretation of the results is carried out taking into account the historiographical framework developed in recent years that considers the medical marketplace as an economic and cultural concept.

    18(th) century philosophers analyzed art through the aesthetic experience of the audience. By contrast, Adam Smith was interested in the moral judgment that an impartial audience may formulate. How can art and morality, the beautiful and the good, be combined into one analytical framework? Art and morality convey non-transcendental values that are intrinsic to human experience. With the aesthetic experience of the audience, art is used, and ultimately depends on the ways that humans relate to works or art and to the beautiful.

    2014-07-01

    Aims: The present high accuracy of stellar positions and proper motions allows us to determine the positional accuracy of old stellar catalogues. This has already been done for the most important catalogues from before the 18th century. Our aim is to extend this study to several 18th century catalogues. Methods: To do this, I studied ten catalogues: those of Flamsteed and Rømer, four catalogues of La Caille, and catalogues of Tobias Mayer, Bradley, Piazzi, and Lalande. A comparison with modern data, mostly from Hipparcos, compiled in the Simbad database of the CDS allowed me to determine the position errors of these catalogues. I also compared the stellar visual magnitudes given in eight of these catalogues with photometric V magnitudes. Results: Thanks to novel instruments, the rms positional accuracy improved from thousands to hundreds of arcsec in older catalogues to less than one minute in that of Flamsteed, and to 2-6 arcsec in the other catalogues I examined. These improvements allowed for the first time relatively accurate proper motions to be determined by 19th century astronomers. The catalogues with some corrections are available in digital form at the CDS via anonymous ftp to http://cdsarc.u-strasbg.fr (ftp://130.79.128.5) or via http://cdsarc.u-strasbg.fr/viz-bin/qcat?J/A+A/567/A26

  1. Analyses of Etna Eruptive Activity From 18th Century and Characterization of Flank Eruptions

    Etna explosive activity has usually been considered subordinate with respect to the effusive eruptions. Nevertheless, in the last decade and overall after the 2001 and 2002 flank eruptions, explosive activity has drawn the attention of the scientific and politic communities owing to the damages that the long-lasting ash fall caused to Sicily's economy. We analyzed the eruptions from the 18th century to find some analogous behavior of Etna in the past. A study of the Etna historical record (Branca and Del Carlo, 2003) evidenced that after the 1727 eruption, there are no more errors in the attribution of the year of the eruption. Furthermore from this time on, the scientific quality of the chronicles allowed us to obtain volcanological information and to estimate the magnitude of the major explosive events. The main goal of this work was to characterize the different typologies of Etna eruptions in the last three centuries. Meanwhile, we have tried to find the possible relationship between the two kinds of activity (explosive and effusive) in order to understand the complexity of the eruptive phenomena and define the short-term behavior of Etna. On the base of the predominance of the eruptive typology (effusive or explosive) we have classified the flank eruptions in three classes: i) Type 1: almost purely effusive; ii) Type 2: the intensity of explosive activity comparable with the effusive; iii) Type 3: almost purely explosive with minor lava effusion (only the 1763 La Montagnola and 2002 eruptions belong to this class). Long-lasting explosive activity is produced by flank eruptions with continuous ash emission and prolonged fallout on the flanks (e.g. 1763, 1811, 1852-53, 1886, 1892, 2001 and 2002 eruptions). At summit craters continuous activity is weaker, whereas the strongest explosive eruptions are short-lived events. Furthermore, from the 18th to 20th century there were several years of intense and discontinuous summit explosive activity, from high strombolian

    The decline in infant mortality is an important part of the secular decline in mortality in the western world. The major causes of the decline are subject to controversy. Individual event records from censuses, church records and land registers from two Norwegian parishes during the years 1814-1878 were registered and linked into individual life course records. Around 15,000 infants, of whom 1500 died, were analysed in depth with Cox regression analysis. The total yearly counts of births and infant deaths from 1735 were analysed using ordinary linear regression. Infant mortality hovered around 23 per cent during the middle of the 18th century and fell to a level around 10 per cent by the end of the 19th century. The decline was strongest during the neonatal period. Women born during the first decade of the 19th century, a decade known for a succession of years with bad harvests, war and high infant mortality, gave birth to infants with increased neonatal mortality. The decline in infant mortality during the first part of the 19th century can thus be attributed to an improvement in the health of the mothers dating back to their own fetal or infant stage. The decline took place in the absence of trained medical personnel.

Those views discussed here were the dualistic, mechanistic one of Rene Descartes (1596-1650), the animistic, vitalistic one of Georg Ernst Stahl (1660-1734), and the monistic, mechanistic one of Julien Offray de la Mettrie (1709-1751). Author stressed that the processes of their view formation were influenced by the wide range of the various political and religious factors as well as the scientific, medical facts and opinions at that time, and that not only the contents of the views but also their historical contexts should be pursued in the study on the medical thoughts.

    Estimating global fluxes of precious metals is key to understanding early monetary systems. This work adds silver (Ag) to the metals (Pb and Cu) used so far to trace the provenance of coinage through variations in isotopic abundances. Silver, copper, and lead isotopes were measured in 91 coins from the East Mediterranean Antiquity and Roman world, medieval western Europe, 16th–18th century Spain, Mexico, and the Andes and show a great potential for provenance studies. Pre-1492 European silver can be distinguished from Mexican and Andean metal. European silver dominated Spanish coinage until Philip III, but had, 80 y later after the reign of Philip V, been flushed from the monetary mass and replaced by Mexican silver. PMID:21606351

    An opportunity was afforded to analyse pigment specimens from an unrestored oil painting in the style of the English School of the mid-18th Century prior to conservation being undertaken. Raman spectroscopy was adopted to characterise the pigments and indicated the presence of a novel red pigment which was assigned to the complex chromium mineral, hemihedrite, in addition to other interesting materials found in combination. This is the first recorded identification of hemihedrite spectral signals in an art context in a range of mineral pigments that are otherwise typical of this period and some hypotheses are presented to explain its presence based on its occurrence with associated mineral pigments. It is suggested that the presence of powdered glass identified in certain areas of the painting enhanced the reflectivity of the pigment matrix.

    John Wesley was an 18th- century Anglican priest whose evangelistic efforts led to the establishment of Methodist Societies in England, Ireland and America. He became greatly concerned for the spiritual and physical health of the poor. Wesley wrote a book entitled Primitive Physick: Or, an Easy and Natural Method of Curing Most Diseases. He was deeply impressed with the few physicians who called for the prevention of disease through healthy living and who recommended time-honored, inexpensive methods of cure. This article reviews Wesley's ideas and prescriptions for healthy living. The discussion reflects on his contribution to the development of a psychology of health and credits Wesley with being ahead of his time in his dietetic and hygienic recommendations. Using Matarazzo's (1982) definition the article shows that over 200 years ago Wesley dealt with each of the major concerns of health psychology and behavioral medicine.

    The 18th century was the time when trauma neurosurgery began to develop into the modern discipline. Before this, the management had, for the most part, changed little from the days of Hippocrates, Celsus, and Galen. Attention was directed to skull injuries, and the brain was treated as the seat of the rational soul but without other function. Symptoms after trauma were attributed to injuries to the bone and meninges. Following the lead of the Royal Academy of Surgery in Paris, it was accepted from the 1730s that the brain was the seat of symptoms after cranial trauma. During the 18th century, at least 12 surgeons published articles on cranial injury, 6 describing significant clinical series on this topic. They were Henri-François Le Dran (1685-1770) of Paris, Percival Pott (1714-1788) of London, James Hill (1703-1776) from Dumfries, Sylvester O'Halloran (1728-1807) of Limerick (Ireland), William Dease (1750-1798) of Dublin, and John Abernethy (1764-1831) of London. This article analyzes these series. Each individual made a different contribution. It is suggested that the relatively lesser-known James Hill in Scotland demonstrated the greatest understanding of the management of brain trauma and achieved the best results. A product of the Scottish Enlightenment, he adapted his management to his own experience and was not tied to the accepted authorities of his day, but he improved the management of each case following his experience with previous patients. He deserves to be remembered.

    The present work is carried out in the frame of the KLIMHIST PROJECT ("Reconstruction and model simulations of past climate in Portugal using documentary and early instrumental sources, 17th-19th century)", and is devoted to the study of hydro-meteorological extreme events during the last 350 years, in order to understand how they have changed in time and compare them with current analogues. More specifically, the results selected to this presentation will focus on some hydro-meteorological extreme events of the 18th century, like severe droughts, heavy precipitation episodes and windstorms. One of the most noteworthy events was the winterstorm Bárbara (3rd to 6th December 1739), already studied in prior investigations (Taborda et al, 2004; Pfister et al, 2010), a devastating storm with strong impacts in Portugal caused by violent winds and heavy rainfall. Several other extreme events were detected by searching different documentary archives, including individual, administrative and ecclesiastic sources. Moreover, a more detailed insight to the 1783-1787 period will be made with regard the Lisbon region, taking into consideration the availability of information for daily meteorological observations as well as documentary evidences, like descriptions from Gazeta de Lisboa, the periodic with more continuous publication in the 18thcentury.

    This paper discusses the differential diagnosis of an unusual calcified mass found in the pelvic cavity of 45+-year-old female excavated from 15th-18th century Lisbon (Portugal). The mass is relatively large, irregularly shaped, and exhibits a concave base with malformed teeth embedded within its inner surface. Considering its macroscopic and radiological characteristics, several conditions were considered in the differential diagnosis, namely eccyesis, fetus in fetu, lithopaedion, and ovarian teratoma. However, the morphological features of the specimen, such as its structure, morphology, and dimensions, are diagnostic of a teratoma. Its location and the sex of the individual are more specifically compatible with a calcified ovarian teratoma. With regional and temporal variations in the frequency of tumours, the report of new cases becomes imperative, especially from geographic regions where few cases have been identified. In fact, this appears to be the first case of ovarian teratoma detected in the Portuguese archaeological record and adds to the few palaeopathological cases described in the osteoarchaeological literature worldwide.

    Forensic medicine in the United Kingdom includes both forensic pathology and clinical forensic medicine on the living. It began at the end of the 18th century, long after its development in Germany, Italy, France, and other countries in Europe. Initial beginnings were in Scotland, where a program began at the University of Edinburgh with the establishment of a chair in Forensic Medicine by Prof. Andrew Duncan Sr. The development in England began in London's Kings College Medical School with a chair held by Prof. William A. Guy. Later chairs in Forensic Medicine were established in Glasgow, Aberdeen, and in London, where Forensic Medicine was taught at St. Mary's Hospital Medical School, Guy's Hospital Medical School, London Hospital Medical School, Charing Cross Hospital Medical School, St. Thomas Hospital Medical School, and St. George's Hospital Medical School. In other cities in England, Wales, and Northern Ireland, departments were founded in Leeds, Manchester, Cardiff, and Belfast. Many textbooks were prepared during this time by professors from these medical schools and by others working in nonacademic areas. The development of coroner activities and those of the police surgeons is also part of the study of forensic medicine.

    2004-06-01

    In the 17th and 18th century republic of letters the problem of scientific fraud was met with a discourse of charlatanism. Departing from Johann Burchhard Menckes famous treatise on the Charlatanry of the learned the following essay traces how the accusations of academic and scientific misconduct put in terms of 'charlatanry' primarily helped to produce the new species of the erudite 'charlatan'. Facing a growing complexity of scientific culture this new frame of meaning, structured by numerous examples of scientific misconduct offered a new way of orientation in the world of learning. But besides its cognitive impacts the discourse of charlatanry allowed to create symbolic boundaries, which determined decisions upon the affiliation or non affiliation to the new forming scientific community by separating honourable from dishonourable scientific personae. Speaking of charlatanry therefore always implied a social distinction as much as a scientific. The discourses on charlatanry also mirror differentiations within the scientific field. At first dominated by a critique built on courteous or bourgeois values, the scientific field later on developed its own criteria of appraisal like authorship, originality, transparency etc. Attracting the attention of a further growing public sphere, the explicit verbalisation of claims not relating to the value system of a republic of letters primarily concerned with the production and distribution of knowledge finally led up to a more implicit moral economy of science. A change that at a large scale level can be described both as an internalisation of the values of scientific conduct and differentiation between justiciable and unjusticiable transgressions of the norms set up by the scientific community.

  17. Comparing ground-penetrating radar (GPR) techniques in 18th-century yard spaces

    NASA Astrophysics Data System (ADS)

    Carducci, Christiane M.

    Yards surrounding historical homesteads are the liminal space between private houses and public space, and contain artifactural and structural remains that help us understand how the residents interfaced with the world. Comparing different yards means collecting reliable evidence, and what is missing is just as important as what is found. Excavations can rely on randomly placed 50-cm shovel test pits to locate features, but this can miss important features. Shallow geophysics, in particular ground-penetrating radar (GPR), can be used to identify features and reliably and efficiently collect evidence. GPR is becoming more integrated into archaeological investigations due to the potential to quickly and nondestructively identify archaeological features and to recent advancements in processing software that make these methods more user-friendly. The most efficacious GPR surveys must take into consideration what is expected to be below the surface, what features look like in GPR outputs, the best methods for detecting features, and the limitations of GPR surveys. Man-made landscape features are expected to have existed within yard spaces, and the alteration of these features shows how the domestic economy of the residence changed through time. This study creates an inventory of these features. By producing a standardized sampling method for GPR in yard spaces, archaeologists can quickly map subsurface features and carry out broad comparisons between yards. To determine the most effective sampling method, several GPR surveys were conducted at the 18th-century Durant-Kenrick House in Newton, Massachusetts, using varied line spacing, line direction, and bin size. Examples of the GPR signatures of features, obtained using GPR-Slice software, from the Durant-Kenrick House and similar sites were analyzed. The efficacy of each method was determined based on the number of features distinguished, clarity of the results, and the time involved. The survey at Newton showed that

This article was written while I was enrolled in a music history course, which afforded me the opportunity to explore music as musical expressions of life. Rooted in the human becoming philosophical perspective, which focuses on unitary human experience and the quality of human life, I discuss musical expressions of life with examples from various composers throughout the 18th and 19th century. This article concludes with a reflection on musical expressions and their contribution to the enhancement of the quality of human life, a focus of nursing from a human becoming perspective.

    This paper deals with public health in Mexico City from the 16th to the 18th century. The first part is about sickness and epidemics; the origin of a very high concerned with death rate at that time; general and private hospitals foundations, and about the role of the Church, Medical Board and the Viceroy in Health Care and Preventive Medicine. Medical care was efficient in these aspects. The second part deals with public services concerning public health as a clean environment and streets and collecting garbage, problems that caused sickness according to the ideas of those days. A clear environment was good until the second half of the 18th century. The paper is divided as follows: introduction; sickness and epidemics; medical care; actions against epidemics; public services, and final commentary.

    The conservator's expertise is defined in Paris in the museum at the end of the 18(th) century. On the one hand, this article analyses the competences claimed by the conservator in order to give proof of his expertise and to create a professional identity distinct from other implicated actors. On the other hand, this text shows how this expertise is constructed through the collaboration between the curator and the conservator, and underlines the negotiation and porosity of their respective fields of competence.

  2. The first Finnish malariologist, Johan Haartman, and the discussion about malaria in 18th century Turku, Finland

    After the Great Northern War in 1721, Sweden ceased to be an important military power. Instead, the kingdom concentrated on developing science. Swedish research got international fame with names as Carolus Linnaeus, Pehr Wargentin and Anders Celsius. Medical research remained limited and malaria was common especially in the coastal area and along the shores of the big lakes. Already in the beginning of the 18th century Swedish physicians recommended Peruvian bark as medication and they also emphasized that bleeding or blood-letting a malaria patient was harmful. Although malaria was a common disease in the kingdom, the situation was worst in the SW-part of Finland which consisted of the town of Turku and a large archipelago in the Baltic. The farmers had no opportunity to get modern healthcare until Johan Haartman was appointed district physician in 1754. To improve the situation he wrote a medical handbook intended for both the farmers and for persons of rank. Haartman's work was first published 1759 and he discussed all the different cures and medications. His aim was to recommend the best ones and warn against the harmful. His first choice was Peruvian bark, but he knew that the farmers could not afford it. Haartman was appointed professor in medicine at the Royal Academy of Turku in 1765. The malaria situation in Finland grew worse in the 1770's and Haartman analysed the situation. He found the connection between the warm summers and the spring epidemics next year. In a later thesis, Haartman analysed the late summer/early autumn malaria epidemics in the archipelago. Althouh Haartman did not know the connection between malaria and the vector, he gave astute advice and encouraged the farmers to build their cottages in windy places away from the shallow bays in which the Anopheles females hatched. Haartman died in 1788. After his death malaria research in Turku declined. His medical handbook would not be replaced until 1844. PMID:21324104

    Thirteen historical Iranian manuscripts belonging to the Qajar dynasty (18th-19th Century BC) were investigated by micro-PIXE technique using Van de Graaff accelerator in the Nuclear Science & Technology Research Institute in Iran. The aim of the present work has mainly been to determine the elemental composition of different inks and papers. In addition, the effects due to the variation of thickness and texture of the paper were simultaneously measured with the off-axis STIM technique. Elemental maps by micro-PIXE were compared to photographs taken in visible light.

    We have determined bone strontium (Sr), barium (Ba), calcium (Ca), and zinc (Zn) content in 24 samples belonging to adult individuals who died toward the end of the 18th century and were interred in a church's floor on the island of Tenerife, comparing the results with those obtained in 14 prehistoric samples of the same island and also with those of 7 modern controls. No differences were observed between the two ancient groups, which showed higher bone strontium and barium than the modern sample, and a slightly lower Ba/Sr ratio, thus pointing to consumption of marine sources.

    We review the small number of known observations of planetary transits made in Ireland in the 18th century with particular reference to the 1769 observations of Venus by Charles Mason. Though inconclusive, there is evidence to suggest that planetary transits were instrumental in the foundation of at least one of the principal observatories in Ireland. In addition, we note the close personal involvement and the contributions of Nevil Maskelyne, the prime mover of the UK 1769 Transit observations, in the design and equipment of these observatories.

    From The Theory of Moral Sentiments to his essay on The Nature of that Imitation Which Takes Place in What Are Called the Imitative Arts, Adam Smith offered a vision of aesthetics combining beauty and utility. An echo of exchange value as the "ability to buy other goods" - the "power" to organize and achieve one's goals - his definition of beauty was premised on the "aptness" of things, that is, the fact that they were also useful. Sustained by the commodification of products, a kind of "techno-aesthetics" thus emerged in England in the 18(th) century, one that implied designing, adapting, reducing and showcasing the means of production.

    Mutations of the Adenomatous polyposis coli (APC) gene are common and strongly associated with the development of colorectal adenomas and carcinomas. While extensively studied in modern populations, reports on visceral tumors in ancient populations are scarce. To the best of our knowledge, genetic characterization of mutations associated with colorectal cancer in ancient specimens has not yet been described. In this study we have sequenced hotspots for mutations in the APC gene isolated from 18th century naturally preserved human Hungarian mummies. While wild type APC sequences were found in two mummies, we discovered the E1317Q missense mutation, known to be a colorectal cancer predisposing mutation, in a large intestine tissue of an 18th century mummy. Our data suggests that this genetic predisposition to cancer already existed in the pre-industrialization era. This study calls for similar investigations of ancient specimens from different periods and geographical locations to be conducted and shared for the purpose of obtaining a larger scale analysis that will shed light on past cancer epidemiology and on cancer evolution.

    Based on single studies, it has been hypothesised that Europeans have suffered less frequently from caries before the 18th century than after the 18th century and that females have higher caries prevalence, but systematic European-wide overviews are sparse. We collected published data on dental diseases (publication between 1981 and 2015 with reports on 29 cohorts with 4998 individuals and a total of 85817 teeth). Meta-analyses revealed that, over several hundred years, including the post-18th century era, Europeans had relatively constant frequencies of caries and ante-mortem tooth loss, but since the 18th century, the mean frequencies of these dental diseases increased (each p<0.05). Tooth loss correlated with caries and odontogenic abscesses (each p<0.05). Although the mean caries and ante-mortem tooth loss frequencies increased since the 18th century, there are overlaps with many pre-18th century cohorts. In addition, in contrast to previous hypotheses, no general increase of caries prevalence in females could in fact be verified. It is likely that changes in nutrition (more sugar) and dental health (possibly higher frequency of tooth extraction) could be the underlying factors which led to this minor to moderate shift of dental disease frequencies in Europe.

    Results have been presented for studies of the microstructure and chemical composition of a number of articles made of iron and cast iron at the Kamensk plant, which cover the period from the start of the production of iron on the territory of the city of Kamensk-Ural'skii at the turn of the 17th-18th centuries to the beginning of the 20th century. Differences in the composition of the Kamensk cast iron and modern grades of foundry cast iron have been established. Possible sources of technological difficulties and production waste at the Kamensk plant have been revealed. The potential of metallographic studies for the attribution of historical articles made of ferrous metals are shown.

    According to standard textbooks, the last episode of European New Age plague pandemic died out by 1720 in Marseilles. Despite this allegation, the pandemic continued in well-documented new outbreaks, which attacked and devastated Central and Eastern Europe throughout the first half of the 18th century. At the beginning, military campaigns spread the infection out of the Ottoman Empire. Later on commercial goods took over this role via land or sea from Asia or out of the eastern Mediterranean region. Finally, the plague in Europe--except Russia and the Ottoman Empire--"died out" virtually by the end of the 18th century. Explaining this, there many scientific reasons were suggested: 1. Oriental rat fleas as main vectors of infection could not tolerate any more the European weather conditions (although there were no virtual climate changes in the last 300 years). 2. Black rats that lived in close proximity to man, were being outplayed by brown rats living rather outside of human habitats; 3. There emerged less virulent Yersinia strains that caused natural human immunisation. In spite of these suggestions, which may have contributed to the success, joint civil and military health authorities blocked the plague indeed, as a result of disciplined and relentless law enforcement. In Hungary, respectively in the Hapsburg Empire, well-advised health legislation backed up the effectiveness of local authorities. Following the last great devastation in 1738-1740, the General Norm of Health Service--a voluminous decree--summed up by 1770 all the time honoured empiric rules of foregoing centuries. It can be excellently demonstrated, how exactly the empiric rules discovered a century later met scientific facts of physiology and microbiology.

    Plant phenological data from northern Finland, compiled from several sources, were examined as potential biometeorological indicators of climate change since the 18th century. A common feature of individual series was their sporadic nature. In addition to waning enthusiasm, wartime hardships and crop failures had caused gaps in recording observations during the 18th and 19th centuries. The present study's challenge was to combine separate records, as retrieved from several historical archives and personal diaries, into a single continuous series. To avoid possible biases due to the variability of data availability each year, each phenomenon-specific mean series was transformed into normalized site-specific index series. These series were compared to each other and to a regional instrumental temperature series (years 1802-2011). The inter-phenomena correlations were high. Moreover, a strong biometeorological response of the phenological series, most especially to monthly mean temperature in May, and seasonally to the April through June temperatures, was identified. This response focused on slightly later spring months compared to the responses in an earlier study conducted for southern Finland. The findings encouraged us to compute a total phenological index series as an average of all available phenomenon-specific index series for northern Finland. The earliest phenological springs were found as a cluster in the recent end of the record, whereas the anomalously-late phenological spring could be found through the centuries. This finding could indicate that potential future warming could result in an earlier onset of phenological springs (i.e. as experienced by the plants), with a remaining possibility of late phenological springs. To conclude, it was shown that the indices are reliable biometeorological indicators of the April through June temperature variations and thus of the climate variability in the region.

    As they became more widely adopted in eighteenth- and nineteenth-century France, wet-nursing and wet-nurses appeared prominently in the iconography of the time. Such images turned negative as criticism against “mercenary breast-feeding” mounted. Over the nineteenth century in particular, wet-nurses were heavily featured in press caricatures: they were being mocked while described as simple-minded, dumb, greedy creatures, with proclivities ranging from a taste for garish attire, to sexual appetites fuelling trysts in public gardens with soldiers on leave. A representative sample of such images will be selected to highlight the codes and values underpinning this mockery.

Father Raimbault, "doctor" and chaplain of the lepers in the middle of the twentieth century, is still honored today. The improvement in living standards and the use of sulfones finally resulted in the control of leprosy. Nonetheless, from 2005 to 2011, an average of three new cases per year were detected among a population of 800,000 inhabitants.

    Two centuries ago, electricity was being used for the treatment of paraplegia and trials were taking place in France. This study aims to identify cases of traumatic paraplegia treated with electricity in the 19th century in order to assess the therapeutic benefit. Only four such cases were identified, none with a complete transection of the spinal cord since these patients would have died from pressure sores and urinary tract infections. The personalities involved, William Gull, William Erb, Guillaume Duchenne and Cyril Henry Golding Bird are portrayed and contemporaneous views on electrotherapy analysed. While the four patients apparently benefited from the treatment, the lack of follow-up and the incomplete data prevented a definitive conclusion on the therapeutic value of electrical treatment in traumatic paraplegia.

    Sanitary and hygienic state of the Baltic navy ships in the 18th century was considered as unsatisfactory due to inappropriate habitation conditions answering hygienic requirements. The reason for the low ship habitation of that time was limited technological possibilities of the sail shipbuilding, lack of appropriate labour, and life and rest conditions for navy servicemen. In fact, wooden ships were not suitable for life activity of the navy crew, but contributed to disease increase. Because of the rapid development of the' navy hygiene and improvement of shipbuilding technologies, sanitary and hygienic state of local navy ships had became improving. With a glance on recommendations, developed by physicians D.P.Sinopeus and A.G.Bakherakht, were made following improvements: were implemented ventilators on ships, daily fumigation of ships rooms, monitoring of personal hygiene.

    During the 17th and 18th centuries, measures were taken by the Venetian administration to combat plague on the Ionian Islands. At that time, although the scientific basis of plague was unknown, the Venetians recognized its infectious nature and successfully decreased its spread by implementing an information network. Additionally, by activating a system of inspection that involved establishing garrisons along the coasts, the Venetians were able to control all local movements in plague-infested areas, which were immediately isolated. In contrast, the neighboring coast of mainland Greece, which was under Ottoman rule, was a plague-endemic area during the same period. We conclude that even in the absence of scientific knowledge, close observation and social and political measures can effectively restrain infectious outbreaks to the point of disappearance.

    The influence of German science and medicine on the development of Hungarian medicine in the age of Enlightenment has been extraordinary strong. Many Hungarian medical students stayed in German medical faculties. The medical interrelationships between Germany and Hungary in the 18th century are discussed in an overview according to the following dimensions: education of protestant Hungarian medical students at German >Aufklaerungs-Universitaeten<, practical and theoretical resonance, membership of scientific societies, personal contacts and correspondence. Outstanding personalities of this area were Daniel Fischer, István Weszprémi, Abraham Vater. Special attention is given to a new idea: inoculation against plague was first described by A. Vater in his work Blattern-Beltzen (1721). Thirty years later I. Weszprémi published his original conception - independently from Vater - in the Tentamen de inoculanda peste (1755).

    The debate which took place in the 1720s at the Royal Academy of Inscriptions and Letters on the possibility or impossibility of understanding the history of the first centuries of Rome is generally interpreted to be less of a debate than an important epistemological clarification. A contextualization which takes into account the political stakes of the debate allows one to understand that the debate was the beginning of a larger process of the autonomisation of the field of historical studies, not only from the perspective of disciplinary divides, but also in relation to monarchal power.

    This overview is mainly focussed on the clay area forming the northern half of the province. It is the wealthiest and most characteristic part, being cultured since the Middle Ages as testified by the many churches that even small villages were able to construct. About 1700 the province of Groningen enjoyed already a modern economy, fitting in with that of the other coastal areas of Friesland, Zeeland and Holland (the last mentioned was the richest region of the world in the 17th and 18th century). As aspects of modernity at that time can be considered: 1) the use of modern agricultural methods with higher yields per hectare and higher milk yields per cow than produced in the land provinces on the sandy soils; 2) Agriculture was aimed at earning money by selling of hte products. In opposition to the farmers in the land provinces, who mainly produced for subsistence farming, the farmers in the coastal areas produced for the trade; 3) A high degree of specialization was found in the rural areas. 30-40% of the families had own farms, 25% of the population were labourers, owing only small pieces of land and the rest of the working population had occupations outside agriculture (craftmen, shopkeepers, shipmasters, merchants etc.). Whereas on the sandy soils practically every family owned a farm, be it mostly a very small one. After reviewing the changes in the distribution of land in use of the production of fieldcrops or for meadows-always in function of the market value of the products-and after a discussion of type of cattle husbandry (breeding, fattening, dairying) it is concluded that a relative decrease of the importance of cattle husbandry in the clay region during the 18th - 19th century can be observed. Intensification of land use had a positive effect on crop-production. The much-heard opinion that the cattle plague epizootic of 1768-1786 caused a transition in land use through a switch from animal husbandry to arable farming, is not held by the author

Current research has related communicational and functional approaches with concepts such as authorship, textual transmission and cultural factors. Very few historians of science, however, have looked systematically at the issue of translation as worth studying in its own right. Yet the history of translation of philosophical and scientific texts calls, in particular, on the transfer of knowledge from ‘centres’ to ‘peripheries’ and could make serious inroads into reception studies.

    Psychiatric care or the care of the mentally ill is very ancient. However, psychiatry is only getting a part of medicine from the end of the XVIIIth Century on. Flemish psychiatric care means care for mental disturbed people in our Flemish countries; also we attend to the influences between opinions from stranger and Flemish physicians, philosophers and humanists. In the Middle Ages popular medicine, "healers" and priests interfere with the practice of the rare contemporary physicians and surgeons. Pilgrimage was the meeting-place for popular medicine, medical and religious acting. In Antwerp, Brugge, Ghent, the first hospices, hospitals and asylums arose. Geel got very well known as a unique centre of family care for crazy people. Mental disease was known as phrenesis (madness), melancholia, mania, epilepsy, rabies. In this period the possibilities of healing remained extremely limited. The Renaissance period was one of Humanism and Reform. The humanists developed a new image of humans. More, Erasmus and Vives were most critical against medieval philosophy and charged the medieval irrational thinking. Vives influenced medical, psychological and psychiatric thinking of his Flemish contemporaries. Also we can talk about the rise of Flemish humanistic medicine. For the Renaissance doctor the concept of passions of the soul as constituting disease states, treatable by opposite passions, set the stage for the consideration of affective disorders themselves as species of madness, whereas previously, madness was seen as a disorder of reason. Halfway the XVIIth Century arose what can be seen as the first biological revolution. The discovery by Harvey of the circulation in a closed system meant a sudden revolution of the Galenic scheme and introduced new ways for the physiology. The Flemish doctor J. B. van Helmont spent a long time to the reform of the medical art. His system was a prefiguration of actual functional affections, symptomatic drug therapy and talk therapy

  10. Venusians: the Planet Venus in the 18th-Century Extraterrestrial Life Debate

    In the seventeenth and eighteenth centuries it became possible to believe in the existence of life on other planets on scientific grounds. Once the Earth was no longer the center of the universe according to Copernicus, once Galileo had aimed his telescope at the Moon and found it a rough globe with mountains and seas, the assumption of life on other planets became much less far-fetched. In general there were no actual differences between Earth and Venus, since both planets orbited the Sun, were of similar size, and possessed mountains and an atmosphere. If there is life on Earth, one may ponder why it could not also exist on Venus. In the extraterrestrial life debate of the seventeenth and eighteenth centuries, the Moon, our closest celestial body, was the prime candidate for life on other worlds, although a number of scientists and scholars also speculated about life on Venus and on other planets, both within our solar system and beyond its frontiers. This chapter discusses the arguments for life on Venus and those scientific findings that were used to support them, which were based in particular on assumptions and claims that both mountains and an atmosphere had been found on Venus. The transits of Venus in the 1760s became especially important for the notion that life could thrive on Venus. Here, I detect two significant cognitive processes that were at work in the search for life on Venus, i.e., analogical reasoning and epistemic perception, while analogies and interpretations of sensory impressions based on prior knowledge played an important role in astrobiological theories.

    This paper presents a short review of the long-distance trade in slaughter oxen in Northwest Europe. The long-term development of the trade is described against the social-economic background of the production and consumption areas. In the 14th century, the Danes obtained the right to sell cattle in certain Dutch cities. From 1500 onwards, the export of oxen from Denmark and the adjacent duchy of Schleswig-Holstein increased considerably. The export reached its peak in the first quarter of the 17th century; registered export in 1612 amounted to more than 52.000 oxen over land and, in 1624, about 10.000 oxen over sea. Part of that export was destined for the Dutch market. Protectionist tax measures taken by the Dutch government and the outbreaks of rinderpest put an end to the regular ox trade in the first half of the 18th century. By decree, local authorities tried to prevent the spread of contagious animal diseases. The history of international cattle trade and hauling, however, indicates that economic motives largely outweighed animal welfare issues. Thus, in addition to addressing the logistics of the trade, this paper also addresses veterinary aspects and animal welfare issues related to the transport of cattle.

  12. Textbooks at the Crossroads: Scientific and Philosophical Textbooks in 18th Century Greek Education

    Greek society of the eighteenth century did not have the institutional or theoretical background for the development of an original interest in scientific pursuits. The contact with the new scientific ideas aimed basically at the assimilation of these ideas in the body of the existing contemplative philosophy and the context where such undertaking took place was exclusively education. At the same time, education was the field where the political and ideological pursuits of various social groups intersected. A quasi modernistic profile of the educational activity was especially favored by a new generation of scholars who wished to assert their distinctive intellectual physiognomy, as well as by the emergent group of merchants who strove to establish their distinctive cultural and political authority. As a result, the new interest in the sciences reflects the confluence of the aims of these two social groups. The study of scientific textbooks, which were produced under these circumstances, depicts the consequences of this confluence and brings to light some important aspects of the social and intellectual environment within which the contact of Greek intellectual life with modern sciences occurred.

    We investigate the growth dynamics of Greater London defined by the administrative boundary of the Greater London Authority, based on the evolution of its street network during the last two centuries. This is done by employing a unique dataset, consisting of the planar graph representation of nine time slices of Greater London's road network spanning 224 years, from 1786 to 2010. Within this time-frame, we address the concept of the metropolitan area or city in physical terms, in that urban evolution reveals observable transitions in the distribution of relevant geometrical properties. Given that London has a hard boundary enforced by its long standing green belt, we show that its street network dynamics can be described as a fractal space-filling phenomena up to a capacitated limit, whence its growth can be predicted with a striking level of accuracy. This observation is confirmed by the analytical calculation of key topological properties of the planar graph, such as the topological growth of the network and its average connectivity. This study thus represents an example of a strong violation of Gibrat's law. In particular, we are able to show analytically how London evolves from a more loop-like structure, typical of planned cities, toward a more tree-like structure, typical of self-organized cities. These observations are relevant to the discourse on sustainable urban planning with respect to the control of urban sprawl in many large cities which have developed under the conditions of spatial constraints imposed by green belts and hard urban boundaries.

    To present the state of knowledge and surgical practice concerning cleft lip and palate leading to the modern era. Bibliographical review. Analysis of the scientific medical, surgical, and odontological literature from the 16th to 18th centuries. Texts and art confirm the existence of cleft lip and palate from antiquity in all cultures; however, the first certain references in Western scientific literature did not appear until the works of Celsus (ca. 25 BC to AD 50) and Galen (AD 129 to 200). Indications for cleft lip surgery appear in the Middle Ages with Albucasis (936 to 1013) and Yperman (1260 to 1332). From the Renaissance period onward, and with the invention of the printing press, numerous authors described their own surgical methods. Given the limitations imposed by pain and infection, the authors of the Modern Age focus on correcting the functional and esthetic defect of the lip with techniques that do not differ greatly from those described in the Middle Ages. The treatment for cleft palate was limited to the creation of "obturators" and surgery for cleft palate was not possible until the 19th century.

    Widely differing conditions applied to practice-oriented medical teaching at universities in the various German principalities or territorial states in the 18th century. Initially, the institutions used by professors as "collegium clinicum" belonged either to foundations or were being run on a private basis. It was only in the second half of the 18th century that these institutions became state-supervised, with the inclusion of the discipline of surgery. The results of such reorganization are demonstrated, taking Halle and the work done by Johann Friedrich Gottlieb Goldhagen as examples.

  16. The construction of the country landscape in Veneto plains (North of Italy) during 18th-21st centuries

    2013-04-01

    This paper focuses on the transformation that has taken place in the last four centuries in Veneto's plain in northern Italy. The analysis of statistical data over a long period of time has made it possible to chronologically reconstruct the gradual transformation of wetlands into arable land, suitable for human settlement and for the development of industrial activities. Particularly relevant are the policies adopted by the Republic of Venice (14th-18th centuries) with regard to the management of waters, policies which were continued by the Italian State after its unification in 1861. The evolution of the concept of land reclamation gradually came to include draining, hygienic, agrarian and environmental factors, paying attention to the specific character of both mountain and lagoon areas. Over many centuries new country areas were created, 2/5 of them located below sea level, which can be cultivated due to complex systems of canalization and water pumping. Both the State and landowners invested capital in a project that was not only meant to sustain private interest but that also met public needs. Since 1882 (when the Baccarini law was passed) the subject of the 'sanitary reclamation' began to be discussed in Italy. This concerned 1/16 of the total surface of the country, 400,000 hectares of which in Veneto, where malaria was directly or indirectly responsible for the death of thousands of people. New livelihoods substituted those of the past: some economies based, for instance, on the harvesting of the marshes' products or on the common use of marginal lands disappeared. The recent process of industrialization in Veneto, often carried out with little consideration for the environment, has eventually opened up a new chapter in the history of the countryside of this region, that of environmental and landscape enhancement.

    During the American colonization in the 18th and 19th century, Africans were captured and shipped to America. Harsh living and working conditions often led to chronic diseases and high mortality rates. Slaves in the Caribbean were forced to work mainly on sugar plantations. They were buried in cemeteries like Anse Sainte-Marguerite on the isle of Grande-Terre (Guadeloupe) which was examined by archaeologists and physical anthropologists. Morphological studies on osseous remains of 148 individuals revealed 15 cases with signs for bone tuberculosis and a high frequency of periosteal reactions which indicates early stages of the disease. 11 bone samples from these cemeteries were analysed for ancient DNA. The samples were extracted with established procedures and examined for the cytoplasmic multicopy β-actin gene and Mycobacterium tuberculosis complex DNA (IS 6110) by PCR. An amplification product for M. tuberculosis with the size of 123 bp was obtained. Sequencing confirmed the result. This study shows evidence of M. tuberculosis complex DNA in a Caribbean slave population. Copyright © 2015 Elsevier Ltd. All rights reserved.

  18. Humeral cross-sectional morphology from 18th century Quebec prisoners of war: Limits to activity reconstruction.

    PubMed

    Weiss, Elizabeth

    2005-03-01

    This study uses measures of cross-sectional robusticity and asymmetry (based on humeral areal and inertial cross-sectional components) to test a prediction from bone remodeling theory that a physically active 18th century Quebec prisoner of war sample (N = 25) should have more robust and asymmetrical humeri than a nonphysically active 20th century New Mexico suburbanite sample (N = 27). Narrative accounts document that prisoners of war engaged in labor-intensive activities, and these activities were confirmed by observations of osteoarthritis and other pathologies. The suburbanite sample, for the most part, did not engage in such activities. The prisoners had higher levels of pathology than the suburbanites (e.g., 80% vs. 22% osteoarthritis; F = 17.95, P < 0.01). For robusticity, the populations did not differ significantly in total area, cortical area, moment areas of inertia about the mediolateral plane, or polar moment area of inertia. The Quebec prison sample did have significantly higher values for moment areas of inertia about the anteroposterior plane. For asymmetry, the populations did not differ in any values (total area, cortical area, moment areas of inertia about the mediolateral plane, moment areas of inertia about the anteroposterior plane, or polar moment of inertia). Thus, examinations of cross-sectional robusticity and asymmetry failed to conclusively confirm the hypothesis that intensive labor leads to changes in humeral morphology. Possible explanations for the lack of differences are discussed, such as poor diet impeding bone remodeling. Nevertheless, the one significant finding suggests that cross-sectional shape is more useful in reconstructing activity patterns than amount of bone in a cross section. Results from this study join those from other recent investigations to suggest that additional controls are required before cross-sectional differences may be confidently attributed to activity patterns.

    There has been a continuing misconception for almost three centuries since the transmission of variolation from Turkey (actually the Ottoman Empire) to England that this was a practice of the Turkish Muslims. There are many sources of cogent evidence that variolation in the 18th century in the Ottoman Empire was opposed by Muslims due to their religious beliefs. This article uses cultural anthropology in its analysis of the reasons for the misconception.

    The presented work is part of the research project, titled "Tecniche murarie tradizionali: conoscenza per la conservazione ed il miglioramento prestazionale" (Traditional building techniques: from knowledge to conservation and performance improvement), with the purpose of studying the building techniques of the 13th-18th centuries in the Sardinia Region (Italy) for their knowledge, conservation, and promotion. The end purpose of the entire study is to improve the performance of the examined structures. In particular, the task of the authors within the research project was to build a WebGIS to manage the data collected during the examination and study phases. This infrastructure was entirely built using Open Source software. The work consisted of designing a database built in PostgreSQL and its spatial extension PostGIS, which allows to store and manage feature geometries and spatial data. The data input is performed via a form built in HTML and PHP. The HTML part is based on Bootstrap, an open tools library for websites and web applications. The implementation of this template used both PHP and Javascript code. The PHP code manages the reading and writing of data to the database, using embedded SQL queries. As of today, we surveyed and archived more than 300 buildings, belonging to three main macro categories: fortification architectures, religious architectures, residential architectures. The masonry samples investigated in relation to the construction techniques are more than 150. The database is published on the Internet as a WebGIS built using the Leaflet Javascript open libraries, which allows creating map sites with background maps and navigation, input and query tools. This too uses an interaction of HTML, Javascript, PHP and SQL code.

  3. Women's translations of scientific texts in the 18th century: a case study of Marie-Anne Lavoisier.

    PubMed

    Kawashima, Keiko

    2011-01-01

    In the 18th century, many outstanding translations of scientific texts were done by women. These women were important mediators of science. However, I would like to raise the issue that the 'selection,' which is the process by which intellectual women chose to conduct translation works, and those 'selections' made by male translators, would not be made at the same level. For example, Émilie du Châtelet (1706-1749), the only French translator of Newton's "Principia," admitted her role as participating in important work, but, still, she was not perfectly satisfied with the position. For du Châtelet, the role as a translator was only an option under the current conditions that a female was denied the right to be a creator by society. In the case of Marie-Anne Lavoisier (1743-1794), like du Châtelet, we find an acute feeling in her mind that translation was not the work of creators. Because of her respect toward creative geniuses and her knowledge about the practical situation and concrete results of scientific studies, the translation works done by Marie-Anne Lavoisier were excellent. At the same time, the source of this excellence appears paradoxical at a glance: this excellence of translation was related closely with her low self-estimation in the field of science. Hence, we should not forget the gender problem that is behind such translations of scientific works done by women in that era. Such a possibility was a ray of light that was grasped by females, the sign of a gender that was eliminated from the center of scientific study due to social systems and norms and one of the few valuable opportunities to let people know of her own existence in the field of science.

    The acceptance of new chemical ideas, before the Chemical Revolution of Lavoisier, in Greek-speaking communities in the 17th and 18th centuries did not create a discourse of chemical philosophy, as it did in Europe, but rather a “philosophy” of chemistry as it was formed through the evolution of didactic traditions of Chemistry. This “philosophical” chemistry was not based on the existence of any academic institutions, it was focused on the ontology of principles and forces governing the analysis/synthesis of matter and formulated two didactic traditions. The one, named “the system of chymists”, close to the Boylean/Cartesian tradition, accepted, contrary to Aristotelianism, the five “chymical” principles and also the analytical ideal, but the “chymical” principles were not under a conceptual and experimental investigation, as they were in Europe. Also, a crucial issue for this tradition remained the “mechanical” principles which were under the influence of the metaphysical nature of the Aristotelian principles. The other, close to the Boylean/Newtonian tradition, was the integrated presentation of the Newtonian “dream”, which maintained a discursive attitude with reference to the “chemical attractions”-“chemical affinities” and actualised the mathematical atomism of Boscovich, according to which the elementary texture of matter could be causally explained within this complex architecture of mathematical “ punkta”. In this tradition also coexisted, in a discursive synthesis, the “chemical element” of Lavoisier and the arguments of the new theory and its opposition to the phlogiston theory, but the “chemical affinities” were under the realm of the “physical element” as “metaphysical point”.

    This brief conceptual history, modeled on Koselleck's Begriffsgeschichte, adds to earlier histories of empathy. It showed that Johann Gottfried Herder, not Robert Vischer, invented Einfühlung as an objective scholarly method during 18th-century absolutist-relativist disputes. Original 18th-, 19th-, and 20th-century scholarly texts demonstrated that continued attempts to redress these disputes drove many of Einfühlung's conceptual transformations. Empathy first appeared in U.S. scientific psychology as a personal characteristic when relativists sought to redress the absolutist-relativist methodological dispute that began between John Watson and Edward Titchener. The conclusion notes limitations to this Begriffsgeschichte. (PsycINFO Database Record (c) 2013 APA, all rights reserved).

A Google search of «Charles Richard de Beauregard». Charles de Beauregard focused his professional work mainly on the treatment of the urethral sequela of blennorrhagia, phimosis and paraphimosis. He introduced to 18th century Spanish society (with purported originality and clear commercial interests) therapeutic methods based on lead acetate that had already been developed in France by Thomas Goulard. The urethral sequela of diseases such as blennorrhagic urethritis, stenotic phimosis and paraphimosis were highly prevalent in 18th century Madrid and required complex solutions for the practice of urology of that era. Charles de Beauregard introduced innovative but not original treatments that were invasive but not bloody and that provided him with fame and social prestige. He advertised his professional activity and marketed his therapeutic products through advertisements submitted to the daily press (Madrid Gazette, Gaceta de Madrid). Copyright © 2015 AEU.

    Due to its floodplain location, Pest was especially prone to damages caused by great flood events. Before water regulation works, the greatest flood events, and the highest rate of destruction occurred during ice jam floods. Whereas in the first half of the 18th century Pest is restricted to the medieval downtown located on a higher terrain (Danube terrace), from the mid 18th century onwards the rapidly growing population established suburbs around the downtown in the lower-lying flood plain. Thus, while in the first half of the century floods were more dangerous for the harvest in the agricultural lands, in the second half of the century at the same place suburbs, urban areas with thousands of inhabitants were prone to the same danger. In the first half of the century at least three particularly large flood events, in 1712, 1732 and 1744, caused increasing problems in the close vicinity of the town (and its lands), the second half of the century - as part of a climatic anomaly (Maldá) famous of its weather extremes - was characterised by two extreme (in 1775 and 1799), at least two larger (1789 and 1795) and some more, medium-sized ice jam floods. While in terms of damaged houses the loss was only some dozens in the early part of the century, several hundreds of houses - actually, complete suburbs were erased by floods in 1775 and 1799. In the poster presentation a series of known damaging 18th-century floods, occurred at Pest, is presented, the short-term impacts (e.g. damages), and medium-, long-term administrative responses as well as related long-term landscape changes influenced by floods and flood protection are discussed. Another important aim of the poster is to present the main reasons why in the 18th century these great ice jam floods caused much greater damages (e.g. percentage of collapsed houses in suburbs) in Pest protected by dams than, for example, in the Buda suburbs with no dams, partly also located in high flood-risk areas, in the immediate

    The extent of damage caused by hydrometeorological events or extremes (HME) has risen up in the entire world in the last few years. Especially the floods, flash floods, torrential rains and hailstorms are the most typical and one of the most frequent kind of natural disasters in the central Europe. Catastrophes are a part of human history and people were forced to cope with their consequences (e. g. material damage, economical losses, impacts on agriculture and society or losses of human lives). This paper analyses the human impacts of HME in the Bohemian-Moravian Highlands (central part of the Czech Republic) on the basis of documentary sources from the 18th-19th centuries. The paper presents various negative impacts of natural disasters on lives and property and subsequent inconveniences of Czech peasants. The preserved archival documents of estates or domains became the primary sources of data (e. g. taxation reliefs, damaged records, reports of afflicted farmers, administrative correspondence etc.). Particularly taxation reliefs relate to taxation system in the Czech lands during the 17th-19th centuries allowing to farmers to ask for tax alleviation when their crops were significantly damaged by any HME. These archival documents are a highly valuable source for the study of human impacts of natural disasters. Devastating consequences of these extremes affected individual farmers much more than the aristocracy. Floods caused inundations of farmer's fields, meadows, houses and farm buildings, washed away the arable land with crops, caused losses of cattle, clogged the land with gravel and mud and destroyed roads, bridges or agricultural equipment. Afflicted fields became worthless and it took them many years to become became fertile again. Crop was also damaged by hailstorms, droughts or late/early frosts. All these events led to lack of food and seeds in the following year and it meant the decrease of living standard, misery and poverty of farmers. Acquired

    Systematic entomology flourished as a branch of Natural History from the 1750s to the end of the nineteenth century. During this interval, the "era of Heroic Entomology," the majority of workers in the field were dedicated amateurs. This article traces the demographic and occupational shifts in entomology through this 150-year interval and into the early twentieth century. The survey is based on entomologists who studied beetles (Coleoptera), and who named sufficient numbers of species to have their own names abbreviated by subsequent taxonomists. In the eighteenth century, 27 entomologists achieved this level of prominence, of whom 37% were academics, 19% were doctors, 11% had private incomes, 19% were clergymen, and 8% were government officials. Many of those with private incomes were members of the European aristocracy, and all but one were European men. The nineteenth century list included 192 entomologists, of whom 17% were academics, 16% were museum curators, 2% were school teachers, 15% were doctors, 6% were military men, 7% were merchants, 2% were government entomologists, 6% had private incomes, 5% were clergymen, 5% were government officials, and 4% were lawyers. The demographics of entomology shifted dramatically in the nineteenth century. Whereas many of the noteworthy entomologists of the eighteenth century were German, Swedish, or French, in the nineteenth century, many more European countries are represented, and almost one-fifth of the noteworthy entomologists were from the United States. The nineteenth century list, like the eighteenth century list, contains no women. By the twentieth century, 63% of 178 noteworthy systematic entomologists were paid professionals, teaching entomology courses in universities, or studying insect taxonomy in museums and government-sponsored laboratories. Only one person on the twentieth century list had a private income, but women (ten individuals) were included on the list for the first time.

    The Practica medicinae represented the books written in Europe before the end of 18th century that dealt with individual deseases. In total, 100 Practica books, written by 95 authors, were collected and divided into four periods from the early 11th to the end of 18th century. The first Practica book was written at the Salernitan medical school on the basis of ancient medical books in the basic style, dealing with regional deseases arranged in "a capite ad calcem" manner, as well as with the fevers. The basic style comprised a majority in the first period and decreased gradually, becoming a minority in the 3rd and 4th periods. Sennert's practica was the largest and it elaborated with precise construction. The additional categories, such as female, children, and surgical deseases increased in the later periods. Those written in non-basic style based on pathogenesis or in alphabetical order also increased in the later periods. The practica books changed slightly and gradually, indicating the essential consistency of the concepts of diseases in these periods.

    As a result of a process initiated by the end of the 1 7th century, in the second half of the 18th century the history of medicine became an autonomous branch of the medical knowledge. The uses of the past were no longer those which prevailed in the Renaissance times, and the inherited knowledge played no more a significant role in the production of active medical knowledge. The ideas of the French anatomist and doctor Félix Vicq d'Azyr (1748-1794) on the history of medicine represent an original synthesis of the new frames of historical thought, from a theoretical and methodological point of view as well as in regard with the institutional and pedagogical functions of medical history. Vicq d'Azyr was the first, in fact, to assign to what he viewed as an independent discipline a specific place as a new chair in medical education.

    The article discusses the main changes in legislation concerning granting the licenses for opening a new pharmacy in Bologna in the Middle Ages and Early Modern period. The organization of all traders, including apothecaries, was subordinated, as almost everywhere in Italy, to the Guilds. In the 2nd half of 16th century the Arte de' Speziali of Bologna came under the jurisdiction of the Collegio di Medicina, leading to disagreements between the two corporations. Giovanni Baldi, in his Notizie storiche su la farmacia bolognese (Bologna, 1955) mentioned one of these controversies, dating on the second half of 18th century. The Authors present this controversy basing on original documents from Archivio di Stato di Bologna.

    Congenital malformations are mentioned in Assyrian and Babylonian literature, and the opinions of Democritus, Empedocles and Aristotle regarding their origin persisted in modified form until the Middle Ages. Following the invention of printing, illustrations of congenital malformations began to appear on pamphlets. Although not always realistic, these illustrations provide a rich source of information regarding the spirit of those times. The first monographs containing collections and interpretations of malformations appeared in the 16th century. These were followed in the 17th century by increasingly realistic illustrations, and superstitious ideas regarding the causes of malformations, although still predominating, gradually started to recede.

    Anthropometric literature on the American territories of the Hispanic monarchy before their independence is still scarce. We attempt to expand the field with a case study that includes some important novelties. Albeit our main source, the military records of the Censo de Revillagigedo (conducted in the early 1790s), has already been used, the sample size and the geographical scope are unprecedented: 19,390 males of four ethnicities (castizos, españoles, mestizos, and mulatos) aged from 16 to 39 from 24 localities, including towns and villages scattered across central regions of the Viceroyalty of New Spain. We build a database that, complemented with information on resource endowments obtained from other sources, permits to analyze the determinants of height. Our results show the importance of spatial differences as well as the significance of ethnicity, occupation, rurality, age and resource endowments as determinants of height. Unprivileged mulatos are only 0.5cm shorter than, assumedly privileged, españoles in the "first world" (El Bajío) and 1.3cm taller in the "second world" (Eastern Central Highlands). In turn, living in the "first world" implies being between nearly 1.5cm and 5cm taller than the inhabitants of the "second world". Our estimates of physical statures are placed within an international comparative context and offer a relatively "optimistic" picture. Copyright © 2016 Elsevier B.V. All rights reserved.

  18. The changing face of hospital care in the 18th-century Upper Normandy: the hospital of Caudebec and the arrival of "paying inmates" (1693-1789).

    PubMed

    Robichaud, Marc

    2005-01-01

    This article questions the view that hospitals in early modern France were static and inflexible institutions. The small-town hospital of Caudebec in present-day Upper Normandy underwent three major transformations during the course of the 18th century. Founded in 1693 as a "local" hospital, the institution was designated as an hôpital général in 1724 and began incarcerating beggars and vagrants. Later, with the influx of sick and wounded soldiers brought on by the Seven Years' War, the hospital took on the functions of a small military hospital. On the eve of the French Revolution, the hospital's "civilian" population contained a growing number of individuals who offered to pay for the cost of their care. The arrival of these groups of "paying inmates" shows that the Caudebec hospital was capable of adapting to changing circumstances and was able to respond to the new priorities of the State.

    A corrosion product rarely reported in the literature has been found on the copper support of three miniature paintings of the 17th and 18th centuries. This product, which has been identified as dicoppertrihydroxyformate (Cu2(OH)3HCOO), is an unusual basic copper formate found on copper artifacts. The identification and characterization of dicoppertrihydroxyformate was carried out directly over the corroded surface of the objects, using a nondestructive approach, which combines the integrated use of various microanalytical techniques. Using this approach, it was possible to obtain a set of new reference data about the natural form of Cu2(OH)3HCOO, that will enable its unambiguous identification in other similar objects. In this work, the probable causes that may have contributed to its formation are also discussed.

    This article explores the history of the San Juan de Dios Hospital in Cartagena de Indias, at the end of the 18th century. Its activities and evolution cannot be understood unless they are analyzed within the context of the Bourbon sanitary reforms. it was precisely at that time when these reforms were being implemented in Nueva Granada. One of the goals of the reforms was to improve the health of the population in order to discipline the vassals, to promote the growth of the workforce and to increase the Crown's wealth. The text reviews different aspects of the institution, and how it operated. It examines the budget, its expenses, and the dynamics of the hospital population and of its employees. In doing so, it intends to explain what the hospital offered to the city's various social groups.

    The significance of leprosy in the Viceroyalty of Nueva Granada in the transition from the 17th to the 18th century is analyzed. In addition, we analyze treatments recommended by physicians in the viceroyalty, which were closely related with the etiology and pathogenesis which all doctors attributed to Saint Lazarus's disease. The diversity of opinions led to different therapeutic measures, not only with regard to alleviating the patient's symptoms, but also with a view to preventing it to spread to the rest of the population. As a guiding theme we use the theories defended by the most representative physicians in the viceroyalty, and the views of patients themselves and the society they lived in.

    In the summer of 1796, Pedro María González, a surgeon trained at the College of Cadiz, took part in an expedition commissioned by the Cadiz Consulate with the aim of initiating trading relationships with Smyrna, the most important commercial centre in the Ottoman Empire. On his return, he wrote a document to facilitate future business ventures by Spaniards, describing in detail the customs and traditions of the various social and ethnic groups that inhabited the city of Smyrna. In this paper, I analyse the view of the Turks held by Europeans in the 17th and 18th centuries and the ideological and conceptual factors underlying their negative opinions. I then describe the viewpoint of González himself, especially in relation to Jews, the ethnic group he studied in greatest depth. The fact that they shared a common language, Spanish, undoubtedly facilitated his relationships and his close analysis.

    Ancient DNA analyses have shown to be a powerful tool in the joint transdisciplinary assessment of archaeological records involving human remains. In this study we set out to identify single inhumations by synoptically evaluating the historical, archaeological, anthropological and molecular records on human remains from the crypt of the aristocratic family of Hoheneck (or: Hohenegg) dating to the 18(th) and 19(th) century AD. A total of 11 individuals were under investigation, yielding complete autosomal and Y-chromosomal STR profiles for 5 persons clearly showing a family group. DNA results, anthropological data and archaeological records taken together resulted in (almost) unambiguous correlation to historical records on the persons entombed in the crypt.

    Analysis of the archaic customs of burying the deceased in Srem, primarily amongst Serbs, in the second half of the 18th century is the essential part of the paper that aims at clarifying the consequences of this negative habit onto the spreading of plague epidemic. The Austrian Empire tried to stop and prevent the epidemic with an array of legal norms, but in practice, these orders were often not upheld. Serbian Metropolitans Pavle Nenadović and Stefan Stratimirović insisted on eradicating superstition and retrograde, often uncivilized actions in burial rituals, and they partially succeeded. The example of plague in Irig and the surroundings in 1795-1796 explicitly shows the hazardous effects of the inadequate attitude towards the deceased as one of the factors in spreading the epidemic. Using primary archives, and published sources, with adequate literature, authors depict this complex historical process.

    Case reports in medicine serve as a tool to collect and to transfer knowledge. A special kind of case report in forensic medicine during the 18th and 19th centuries was the so-called Visum repertum. This format of note-taking and of rendering an expert opinion without presuppositions has rarely investigated in the history of medicine. Analyzing Visa reperta the authors argue that due to their special structure and mode of representation Visa reperta not only shaped the practice of forensic medicine but also the standardized examination and documentation in pathological anatomy. Based on previous studies on medical case reports, medical expert witnesses in court and traditions in pathological anatomy the authors examine two examples from the 18th and 19th centuries in order to show how semiological, classifying methods of presenting forensic examinations were replaced by the material aspect of the observation of examination results itself. The examples are a forensic case report by Michael Alberti (1682-1757) from 1728 and a Visum repertum by Joseph Bernt (1770-1842) from 1827. The authors argue that Visa reperta transcended their original forensic purpose and served as a guideline for pathology leading to an understanding of the origin of diseases in organs. They served as a promoter of scientific medicine, and their persuasiveness was backed by factors such as (a) the extreme conditions of forensic practice, (b) the claim to act as a tool for the sound and precise recording of facts and c) the awareness that they documented objects that were destroyed during the process of documentation.

    Conservation efforts for heritage buildings require a substantial knowledge of the chemical makeup of materials that were used throughout the lifetime of the property. In particular, conservators are often concerned with the identification of colorants used in both interior and exterior wall treatments (paint, wallpaper, etc.) in order to gain perspective into how the building may have appeared during a certain time period in its existence. Ideally, such an analysis requires a technique that provides molecular level information as to the identity of the colorant as well as other sample components (binders, fillers, etc.), which is useful for dating purposes. In addition, the technique should be easily applied to paint layer samples which can be extremely thin and fragile. Herein we report the surface-enhanced Raman spectroscopy (SERS) analysis of paint and wallpaper samples taken from exterior and interior surfaces of a historic building. Several pigments were identified in the samples, which ranged from early inorganic pigments (lead white, barium sulfate, calcium carbonate, anhydrous chromium(III) oxide) which have been used in house paints for centuries, to a more modern pigment (phthalocyanine blue), developed in the middle of the 20th century. This analysis highlights the usefulness of SERS in such a conservation effort, and demonstrates for the first time pigment identification in house paints and wallpaper using SERS, which has far-reaching implications not only in the field of conservation, but also in forensics, industrial process control, and environmental health and safety.

    Informed consent is a question of central importance in contemporary medical ethics, and clinical practice is inconceivable without considering the issues it raises. Although it is often vigorously argued that consent, informed or otherwise, is a recent phenomenon and that no sources testify to its existence before the 20th century, it is difficult to accept that a process for regulating the common and fundamental parameters in the relationship between doctor and patient and the planning of treatment had not concerned previous eras. A review of the Registers of the Islamic Court of Candia (Heraklion) in Crete, a series of records that touches on, among other things, matters of medical interest, reveals that the concept of informed consent was not only known during a period that stretched from the mid-17th to the early 19th century, but it was concerned with the same principles that prevail or have been a point of contention today. An extension of this study into other periods may thus provide contemporary researchers with material and information valuable in the discussion of today's bioethical issues.

    Gerald Rutherford (1964), one of the original authors of the Harvard Project Physics course which emphasized the history of science, expressed a view of inquiry which advocated the historical re-constructions of significant experiments. To implement this view we examine two modes of historical re-constructions; Heering's ( Paper presented at the Itinerant Physicists of the 17th century Conference, Pognana, Italy, June 1-6, 2003) replication method for historical experiments and our development of historical representations. Heering describes the replication method in three phases: the construction of the apparatus, the recreation of the experimental procedure, and the contextualisation of the experience. In our adaption of this process for the science classroom we recognize teachers have limited access to methods and resources in historiography. Consequently, the historical re-construction is guided by a historical narrative. As it relates to a historical experiment the narrative has four parts; Introduction, Experimental design, Experimental results, and Analysis.

    Schlumbohm, Jürgen

    In the eighteenth century, lying-in hospitals were founded in many European towns and cities. The way in which these institutions were financed differed greatly across Europe. In the UK, most of them were "charities" and relied on donations from wealthy benefactors, whereas on the continent they were usually funded by "public" money, be it from the state or local communities. The paper focuses on British charities and German hospitals, and explores the corollaries of the mode of financing. In the eighteenth century, a market emerged in Britain where numerous charities with different aims competed for donations from the well-to-do. For attracting benefactors, a charity had to convince potential donors that its clientele and purpose were particularly deserving, and that it used the money donated in a cost-efficient way. In Germany, it was mainly bureaucrats and governments who had to be persuaded, but public opinion did matter as well. In British lying-in charities, the main donors acted as governors, and benefactors could recommend persons for being admitted. In publicly funded German hospitals, the medical directors had much more power. In the competitive market, in which British charities acted, out-patient dispensaries (policlinics) became increasingly important, since they could argue that they were more cost-efficient and had lower mortality. In Germany, however, hospitals remained the dominant type of assistance in this field, in spite of the criticism they received. The different sources of finance appear to have been one of the reasons for this divergence. Teaching was the main purpose of most German lying-in hospitals. They either trained medical students or midwife apprentices or both. Since the patients served as teaching objects, all women were welcomed, and in fact most patients were single mothers. By contrast, most of the British institutions admitted only married women, because donors did not wish to encourage immorality. The charities staged the

    This study proposes a proteomic-based strategy for the identification of the origin species of glues used as binding media and adhesives in artworks. The methodology, based on FTICR high resolution mass spectrometry, was evaluated on glues from different animal origin (i.e., bovine, rabbit, and fish). The analysis of the peptide mixture resulting from the enzymatic hydrolysis of the proteins led to the identification of species-specific peptides. Up to 15 specific peptides were identified for the bovine species and three for the rabbit species and, in the case of sturgeon glue, three fish-specific peptides were found by sequence homology to the rainbow trout. Then, the method was applied to authenticate different rabbit skin glue samples, including a 100 year-old sample named "Colle à Doreurs" coming from the "Maison Totin-Frères". For this sample, two specific peptides of rabbit collagen were identified. To evaluate the method in a complex matrix, model paints composed of lead white, linseed oil, and animal glue were prepared. Species-specific peptides were identified in each paint sample. Finally, a gilt sample from St Maximin church dating from the eighteenth century was analyzed, and 13 peptides specific to bovine collagens were identified starting from very low sample amount (50 μg).

    In the scientific project "Klosterneuburg Wine and Climate Change in Lower Austria" (BACCHUS), we focused on developing a grape harvest date (GHD) time series for the period 1523-2007 in the area of and around Vienna, one of the northeasternmost regions in Europe where vines are grown professionally. Since grape harvest dates are strongly influenced by spring to (early) summer temperatures, especially in a vine-growing region at a climatic border, we found highly significant correlation coefficients between homogenized multiple monthly mean temperatures at Vienna, Hohe Warte, and GHD. For example, correlation values reach -0.76 (p = 0.01) between GHD and April to July mean temperature or -0.79 (p = 0.01) between GHD and May to July mean temperature. This made it possible to reconstruct May to July mean temperatures, starting in 1523. The years from 1775 to 1850 were used as calibration period for determining the temperature sensitivity of GHD, as the running correlation coefficients (10 year moving window) were most pronounced in this period, varying between almost -1 and -0.7 (p = 0.05). We found warm decades in the 16th century, at the beginning of our series, which were as warm as the 1990s. Afterwards the mean May to July temperatures started to drop; the coldest decade of the record was from 1771 to 1780. A constant temperature increase for more than 30 years, as from the 1970s to the present, seems to be unprecedented during the last 470 years.

    This article analyzes the inquisitorial trial of Maria Duran, a Catalan novice in the Dominican convent of Nossa Senhora do Paraíso in Portugal. Maria Duran was arrested by the Inquisition in 1741 and, after a lengthy trial, condemned in 1744 to a public lashing and exile. She was suspected of having made a pact with the Devil and was accused by many female witnesses of possessing a "secret penis" that she had allegedly used in her amorous relations with fellow nuns and novices. Her voluminous trial dossier offers a rare and fascinating documentary insight into the often extreme reactions that female homosexuality provoked from both men and women in early modern Portugal. Using the evidence offered by the 18th-century trial of Maria Duran, this article highlights female bewilderment when faced with female-on-female sexual violence and the difficulty that men (in this case, churchmen) had coming to terms with the existence of female homosexuality. It also discusses the case in light of the acts/identity debate among historians of the history of sexuality.

    The slow but significant changes in the material culture of European households that took place in the pre-industrial period are visible in several ways, such as in the changing patterns of housing, furnishing and clothing which have been illustrated in several studies. However, most of these studies focus on the pre-industrial economic leaders, often ignoring the changes taking place on the margins of the economic growth centres. This article seeks to rectify this by looking at changes in the material culture in one such 'marginal' country, namely Norway. The goods focused upon in this case are sugar, tobacco and coffee, which are often termed as exotic goods. These were new commodities in the 18th century and precisely because of their novelty and foreign origin, it is in many cases possible to trace how they spread in rural society, as well as how they impacted it. The emphasis has been put on rural areas for the simple reason that this was where the overall majority of Norwegians lived at the time.

    The Jesuit college in the Czech town of Klatovy was founded in 1636 and canceled in 1773. It had its own grammar school and numerous contacts with local nobility and church dignitaries. The college was the most important house of a catholic order in the area and baroque festivities organised by the jesuits were visited (or it would be better to say taken part in) by a wide spectrum of members of the local society. The Jesuits concerned not only on careful arrangement of their ecclesiastical celebrations, but also on presence of the important guests. They recorded numbers of the guests who visited the college and their social status in the college manuscripts. The records were then used for an internal need of the order. Till the present day three manuscripts related to the college in Klatovy have been preserved. The most interesting records of the guests are in the diary of father "minister" of the college. The article focuses on a reconstruction of a not very conventional view of social structure in an average Czech town in the beginnig of 18th century. I'm trying to describe the social situation from the jesuit point of view using internal records of the order.

    Optical coherence tomography (OCT) is especially attractive for the study of cultural heritage artifacts because it is noninvasive and nondestructive. We have developed an original full-field time-domain OCT system dedicated to the investigation of varnished and painted artifacts: an interferometric Mirau objective allows one to perform the scan without moving the works of art. The axial and transverse high resolution (respectively, 1.5 and 1 microm) are well adapted to the detection of the investigated structures (pigment grains, wood fibers, etc.). The illumination spectrum is in the visible range (centered at 630 nm, 150 nm wide) to potentially allow us to perform spectroscopic OCT on pigment particles. The examination of wood samples coated with a traditional finish, demonstrates the ability of the system to detect particles, characterize layers thickness, and image the three-dimensional wood structures below the varnishes. OCT has finally been applied to study in situ the coated wood surface of an 18th century Italian violin and provides important information for its conservation treatment.

    The history of medicine abounds in cases of mysterious deaths, especially by infectious diseases, which were probably unresolved because of the lack of knowledge and of appropriate technology. The aim of this study was to exploit contemporary technologies to try to identify the cause of death of a young boy who died from a putative "infection" at the end of the 18th century, and for whom an extraordinarily well-preserved minute bone fragment was available. After confirming the nature of the sample, we used laser microdissection to select the most "informative" area to be examined. Tissue genotyping indicated male gender, thereby confirming the notary's report. 16S ribosomal RNA sequencing showed that Proteobacteria and Actinobacteria were more abundant than Firmicutes and Bacteroidetes, and that Pseudomonas was the most abundant bacterial genus in the Pseudomonadaceae family. These data suggest that the patient most likely died from Pseudomonas osteomyelitis. This case is an example of how new technological approaches, like laser microdissection and next-generation sequencing, can resolve ancient cases of uncertain etiopathology. Lastly, medical samples may contain a wealth of information that may not be accessible until more sophisticated technology becomes available. Therefore, one may envisage the possibility of systematically storing medical samples for evaluation by future generations.

However, given that only two of his works have been translated into Czech and one of them also partially into English, the results of his extensive research activities are currently unavailable not only to the international scientific community, but also to the Czech scientific community. Although his research reflected the time in which he lived and thus has been re-evaluated by later researchers, his achievements undoubtedly belong to the major intellectual heritage of Czech science and certainly deserve attention as such. It is therefore our duty not only to remember the work and legacy of Jirí Procháska, which significantly influenced the development of our knowledge, but also to try to critically assess his contribution in terms of today. The article surveys the important biographical events of Jirí Procháska's life, taking into account the importance of his research and teaching.

    The history of medicine abounds in cases of mysterious deaths, especially by infectious diseases, which were probably unresolved because of the lack of knowledge and of appropriate technology. The aim of this study was to exploit contemporary technologies to try to identify the cause of death of a young boy who died from a putative “infection” at the end of the 18th century, and for whom an extraordinarily well-preserved minute bone fragment was available. After confirming the nature of the sample, we used laser microdissection to select the most “informative” area to be examined. Tissue genotyping indicated male gender, thereby confirming the notary’s report. 16S ribosomal RNA sequencing showed that Proteobacteria and Actinobacteria were more abundant than Firmicutes and Bacteroidetes, and that Pseudomonas was the most abundant bacterial genus in the Pseudomonadaceae family. These data suggest that the patient most likely died from Pseudomonas osteomyelitis. This case is an example of how new technological approaches, like laser microdissection and next-generation sequencing, can resolve ancient cases of uncertain etiopathology. Lastly, medical samples may contain a wealth of information that may not be accessible until more sophisticated technology becomes available. Therefore, one may envisage the possibility of systematically storing medical samples for evaluation by future generations. PMID:28067829

    In this work, we report the unusual concentration of mercury in the hair of an individual buried in the 18th to mid-19th centuries and the comparison with the elemental composition of other remains from the same individual. Two energy dispersive X-ray fluorescence (EDXRF) setups, one with tri-axial geometry and the second one with micro-beam capabilities and a vacuum system, for light elements detection, have been used. Quantitative evaluation of the obtained spectra were made by fundamental parameters and winAXIL program by compare mode method. The levels of Hg in the hair of buried samples presented a concentration over 5% (w/w), a significantly lower presence of this element in the cranium, and no Hg in the remaining organs. Furthermore, there was no evidence of Hg in the burial soil, which has been also analyzed. From this result, we could conclude that the possibility of post-mortem contamination from the burial surroundings is very unlikely. The obtained results are indicative of the apparent use of a mercury-based compound for medical purposes, most likely lice infestation. Copyright © 2015 Elsevier GmbH. All rights reserved.

    In 1720 Catherine Walpole the 16-year-old eldest daughter of Robert Walpole, later to become Prime Minister, became very ill. She was unable to eat, fainted, took fits frequently, and had a persistent pain and swelling in her side. Sir Hans Sloane, the Walpole's doctor, referred her to Dr Cheyne in Bath because he specialized in dietary problems and nervous diseases. Cheyne kept in regular touch with Sir Hans by letter and this correspondence tells the story of Catherine's treatment from her first referral to Cheyne to her death in 1722. The contents and purposes of treatments he used are identifiable in dispensatories of the period. The letters reflect Cheyne's medical skills and knowledge as well as his sympathetic personality. Catherine's family loyalties, personal concerns and personality also emerge as the correspondence progresses. The limitations of 18th-century diagnosis and treatments available are clear but Cheyne is always concerned with Catherine's quality of life, even when he becomes aware that he cannot cure her.

    Jorge Juan and Antonio de Ulloa, naval officers of the Spanish Navy in the Midshipmen's Royal Academy were appointed to take part in one of the most important scientific expeditions of the 18th century. The question of the shape of the Earth, of vital importance for navigation, was solved by the Paris Academy of Sciences by request of Louis XV of France in 1735. The aim was to determine the form of the ellipsoid that Newton had described in the 17th century for any spherical and homogeneous body in rotation about an axis. Two expeditions were prepared for the geodetic measures of meridian arc both in high latitudes (Lapland, Finland) and in the equatorial zone (the Kingdom of Peru); Pierre Louis Maupertuis took charge of the northern expedition whereas the second one was charged to La Condamine, along with Jorge Juan and Antonio de Ulloa. The results obtained by the Spaniards were gathered in a publication: Observaciones astronómicas y físicas hechas en los Reinos del Perú. In it, they dedicate a chapter to the determination of astronomic longitude with the only technology that was providing certain precision at the moment: the simultaneous observation of the same astronomic phenomenon in two different places. Specifically, they explain in detail in Book III: Las Observaciones de la Inmersiones y Emersiones de los satélites de Júpiter, como asimismo de los eclipses de Luna; de las cuales de deduce la Longitud de los Lugares, incluyendo las correcciones a efectuar por la variación de la declinación diaria del Sol.

  6. The priority dispute over the function of the lymphatic system and Glisson's ghost (the 18th-century Hunter-Monro Feud).

    Basic Immunology has had only two significant public priority disputes. The first began in the late 1650s and concerned the recognition of the peripheral network of vessels which collects lymph throughout the body. The publication of this major anatomical discovery prompted a priority feud discussed in a previous paper. The subject of this essay is the second dispute which occurred a century later in the late 1750s. It focused on the function of the lymphatic system and precipitated a heated war of words between a young Scotch medical graduate (Alexander Monro) and a noted London anatomist (William Hunter). Their published charges and responses ranged from feigned respect to ad hominen invectives. But in retrospect, the priority claims of both were precluded by the observations and speculations of an Englishman (Francis Glisson) a full century before. The several editions of his work were unknown to Hunter and Monro at the inception of their feud.

    This study aims at a comprehensive analysis of ethnoveterinary treatment in the cattle-raising section of Sanrimgyeongje which covers 12 different volumes of literature including 4 Korean and 8 Chinese literatures from the 7th to the 18th century, with a special attention to the treatments for cattle diseases. The above mentioned literature was analyzed through several steps: translation of the Chinese text into Korean, identification of diseases, verification of medicinal materials and confirmation of scientific names. As recorded in the thirteen references, this study shows that there are 143 medicinal materials which have been used as therapies for cattle diseases. Of these, 55 plant species belonging to 52 genera in 29 families had 100 modes of usages, while one species of fungus was used in one way. Likewise, 11 species of animals belonging to 11 genera in 10 families were utilized in 18 different methods. Lastly, 9 kinds of inorganic matters were used in 11 ways with another 4 kinds being useful in 14 different ways. Consequently, each of rinderpests, murrains, and hooves has been treated, respectively with 14, 10 and 3 types of medicinal decoctions made from 35, 18 and 15 kinds of medicinal materials. This diversified usage of various medicinal materials is incomparable to the modern ethnoveterinary investigation which tends to focus strictly in plants. If additional studies were to be conducted on these treatments and all the medicinal materials used within them, various new treatments and medicines can be developed to supplement the pharmacopoeia of contemporary veterinary medicine.

    This paper is a part of a general research project on the role that chemistry played in the transition of materia medica to experimental pharmacology during 19th century Spain. Within this general framework, the paper deals with the main characteristics of Spanish textbooks aimed at pharmaceutical and medical students. In a former study, published in this journal, we outlined the institutional context in which these books were read, written and published. Some of these issues are developed in the present paper through analysis of the "Curso de química" written by Pedro Gutiérrez Bueno. New light is shed on the public for chemistry during the late XVIII century Spain and their role in shaping the contents and organisation of chemistry textbooks.

    Systematically recorded daily instrumental meteorological data from the Moravian Brethern mission stations located on the east coast of Labrador and southwest coast of Greenland during the 18th, 19th and 20th centuries provide a most valuable source of historical climatological data in the Subarctic region. Although the collections of original data themselves are both scattered in physical location and fragmented in their coverage of time and place, and large amounts still need to be digitized, this data provides large potential for studying climate extreme events in this remote region. In this paper, we study polar lows (PLs). They are high-latitude intense maritime cyclones with only 200 to 1000 km in diameter, a short life-time of only two days, mostly occurring in wintertime, e.g. in the Norwegian, Barents, but also Labrador and Greenland seas. Due to high wind speeds exceeding 30 m s-1, high ocean waves and heavy snow showers, they constitute a major hazard risk difficult to forecast. Published papers indicate that with future climate warming, the frequency of PLs is predicted to decrease; however, climatologies of PLs for the last 7 decades (1948-2009) based on reanalysis data and satellite remote sensing products did not indicate any change in their mean annual frequency. In our digitized long-term dataset (1846-2015) for one Moravian station at Nain, Labrador, we identified PLs as follows: If there was a drop in air pressure of at least 30hPa during 48 hours, we marked it as a preliminary event. Then, each preliminary event was checked manually to see whether additional changes in air pressure, air temperature, wind direction and wind speed matched the known textbook example. If more than two variables showed the required pattern, the preliminary event was identified as PL. Our analysis revealed an average frequency of 5.6 PLs yr-1 for 1846-1853, 5.2 PLs yr-1(1882-1913), and 4.4 PLs yr-1 (1926-1939), largely confirming long-term averages for the more recent

    During the second half of the 18th century scientific veterinary medicine, a new profession was born as a result of economic and military needs--losses of cattle as a consequence of infectious diseases and the growing demand for treatment to be given to the horses of the armies. At first the members of the emerging occupation, who are generally of very modest origin, hardly differ from the traditional actors of animal health. At the beginning of the 19th century the governments employ a large number of veterinarians for official missions to combat infectious diseases. As from the second half of the 19th century the skills of the veterinarians as doctors for animals and zootechnicians are beginning to be recognized by the rural population, whose increased income allows them more easily to enlist a veterinarian's services. From the 1860s onwards they also start to play a role in the monitoring of public health by controlling foodstuffs of animal origin. But it is only at the beginning of the 20th century that new technological progress, motor vehicles and the telephone (first in the cities, then in the country by way of telephone boxes), makes their work quicker and more efficient. New and strong antiseptics for external and internal use which help to combat many infectious diseases will however appear only around the 1950s.

    Gaab, Hans

    In the second half of the 18th century, Georg Friedrich Kordenbusch (1731 - 1802) was the best-known living mathematician and astronomer in Nuremberg. Being a physician by training, he obtained, in 1769, the post of lecturer in mathematics and physics at the Egidien secondary school. Subsequently, he tried in vain to re-erect the observatory, torn down in 1751. In the early 1770s, he became famous for preparing the second edition of Johann Leonhard Rost's Astronomisches Handbuch that was, in its first edition of 1718, the first compendium of astronomy written in German, and which had a wide circulation. In 1790, Kordenbusch was raised to the nobility for his achievements.

    The words used for designating the caregivers are ambiguous. Little by little, the word "nurse" becomes widely used, mainly in the feminine form due to the need of specialized staff. Health care structures are developing in the 17th and 18 centuries, the remains of which you can find in today hospitals (Salpêtrière hospital, Hôtel-Dieu hospital in Paris). The government of Louis XIV cares for the poor sick people, the vagabonds and the beggars. It opens new general hospitals as it will be the case later in all Europe. In the 17th century, the staff of the general hospital in Paris is entirely secular. The Paris general hospital is headed by the magistrates of Paris Parliament. The healthcare institutions employ both secular and religious staff for example the Hotel Dieu in Paris and the one in Marseilles. In the 17th century, there are 2000 secular caregivers in France. The order of the "Filles de la Charité" (grey sisters) is not submitted to the rule of enclosure. They renew their vows every year. For their founders Vincent de Paul and Louise de Marcillac, their monastery should be the cells of the sick, their cloister should be the rooms of the hospitals or the streets of the town. The secular or religious caregivers are excellent in the apothecary and they open a network of small dispensaries. It improves the health of the French population and allows fighting against the epidemics. This activity allowed some women to have a rewarding activity and a social status of which they were apparently satisfied.

    The Venus transit in June 1761 was the first one to be observed on a truly international scale: almost 250 astronomers followed this rare celestial event (e.g. Wulff 2012, p. 115), and at least 130 published successful observations of it (Aspaas 2012, p. 423). The present paper deals with the astronomical observatories built by the Society of Jesus in its eighteenth century "Provincia Austriae", at which the 1761 transit could be observed. Five Jesuit observatories are being presented in this context: three in today's Austria, namely, two in Vienna and one in Graz; one in Trnava in today's Slovakia and one in Cluj in today's Romania. Thereafter, we briefly examine which of these observatories submitted any Venus transit observations for publication in the appendix to Maximilian Hell's "Ephemerides astronomicae ad meridianum Vindobonensem" for the year 1762.

    Researches aimed at enriching the number of available documentary sources on earthquakes have an important role in seismology. To this end, this paper documents the history of prominent earthquakes associated with the NW-SE trending Sultandag-Aksehir Fault and Aksehir-Afyon graben system in Western-Central Anatolia since the historical times through 1766. This work also combines the earthquake data for both historical and instrumental periods, previously listed in various catalogues and resources, for the studied area. Documents from the Ottoman archives and libraries as well as the Ottoman and Turkish newspapers were scrutinized, and eight previously unreported earthquakes in the latter half of the nineteenth century and four new earthquakes in the period 1900-1931 were revealed. For the period from 1766 to 1931, the total number of known earthquakes for the area under investigation increased from eighteen to thirty thanks to the document search. Furthermore, the existing information on eleven previously reported earthquakes is updated for the period from 1862 to 1946. Earthquakes from 1946 to 1964 are compiled from the catalogues for data completeness.

    During 1969 and 1970, surveys of the endangered Yuma Clapper Rail were conducted using taped calls to elicit responses from the birds. During the two summers, more than 158 Yuma clappers were located in cattailtule marshes along the Colorado River south of Needles, California, to the International Boundary, a distance of about 240 miles. Clappers (probably of the same race) were also found in estuarian marshes of the Colorado River Delta of Mexico; in the Salton Sea; in two freshwater marsh areas near Phoenix, Arizona; and in two freshwater marshes adjacent to the lower Gila River near Tacna, Arizona.....Populations of Sonora Clapper Rails were discovered as permanent residents in five separate mangrove swamps along the west coast of Mexico in the vicinity of Kino Bay, Sonora. These observations were farther north than any heretofore reported for the race R. l. rhizophorae, and the swamps also represent the extreme northward limit of mangroves in Sonora.....During the winter, Yuma clappers did not respond to taped calls north of the International Boundary, whereas clappers along the coast of Sonora readily answered the calls during the same period of time. We conclude that most Yuma Clapper Rails migrate from their summer habitat along the Colorado River in September and do not return to the breeding areas until late April.

    2004-05-01

    The acoustical characteristics of 50 rooms that played a prominent role in the history of music between the 11th and 18th centuries were studied. The rooms include basilicas, oratorios, organ churches, and the great halls and courts of the European palaces. The research provides an understanding of the acoustical features that suit the early music repertoire, and how these rooms achieved an enhanced emotional engagement through their unique acoustical characteristics. This paper provides a summary of the acoustic measurements, which include binaural and B-format recordings in each of the rooms, and presents a unique new approach to understanding their subjective characteristics through detailed analysis and auralization of their 3-D impulse response. The study shows that the timing and direction of reflections in three dimensions is critically important to defining the subjective characteristic of a room. The results emphasize the importance of developing techniques to understand the 3-D impulse response and using auralization techniques for interpreting results and making subjective judgments. The enhanced musical experience that is achieved in these early rooms offers an invitation to rethink modern acoustics and to develop a new design approach that focuses more strongly on the subjective response and emotional engagement of the music.

  5. History of individuals of the 18th/19th centuries stored in bones, teeth, and hair analyzed by LA-ICP-MS--a step in attempts to confirm the authenticity of Mozart's skull.

    A cranium stored in the Stiftung Mozarteum in Salzburg/Austria which is believed to be that of Mozart, and skeletal remains of suspected relatives which have been excavated from the Mozart family grave in the cemetery in Salzburg, have been subjected to scientific investigations to determine whether or not the skull is authentic. A film project by the Austrian television ORF in collaboration with Interspot Film on this issue was broadcast at the beginning of the "Mozart year 2006". DNA analysis could not clarify relationships among the remains and, therefore, assignment of the samples was not really possible. In our work this skull and excavated skeletal remains have been quantified for Pb, Cr, Hg, As, and Sb content by laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) to obtain information about the living conditions of these individuals. A small splinter of enamel (less than 1 mm(3)) from a tooth of the "Mozart cranium" was also available for investigation. Quantification was performed by using spiked hydroxyapatite standards. Single hair samples which are recorded to originate from Mozart have also been investigated by LA-ICP-MS and compared with hair samples of contemporary citizens stored in the Federal Pathologic-Anatomical Museum, Vienna. In general, Pb concentrations up to approximately 16 mug g(-1) were found in the bone samples of 18th century individuals (a factor of 7 to 8 higher than in recent samples) reflecting elevated Pb levels in food or beverages. Elevated Pb levels were also found in hair samples. The amount of Sb in the enamel sample of the "Mozart cranium" (approx. 3 mug g(-1)) was significantly higher than in all the other tooth samples investigated, indicating possible Sb ingestion in early childhood. Elevated concentrations of elements in single hair samples gave additional information about possible exposure of the individuals to heavy metals at a particular point in their life.

    Cribra orbitalia (CO), or porotic hyperostosis (PH) of the orbital roof, is one of the most common pathological conditions found in archaeological subadult skeletal remains. Reaching frequencies higher than 50% in many prehistoric samples, CO has been generally attributed to a variety of factors including malnutrition (e.g., megaloblastic anemia) and parasitism. In this study, we tested the relationship between CO, trace element concentrations, and stable isotope values (δ(13)C, δ(15)N, δ(18)O) in subadult skeletons from a 17(th) to 18(th) century cemetery in the historic town of Jēkabpils, Latvia. A total of 28 subadults were examined, seven of which (25%) showed evidence of CO. Bioarchaeological evidence indicated high mortality for children in this cemetery: half of the burials were subadults under the age of 14, while a third were under the age of four. Life expectancy at birth was estimated to have been only 21.6 years. Trace element concentrations measured by Inductively Coupled Plasma - Mass Spectrometry (ICP-MS) showed no relationship between presence or absence of CO and levels of manganese, zinc, strontium, barium, copper, cadmium, or lead in the bones (p>0.05). However, a significant correlation (p<0.05) was found between the presence of CO and decreased levels of iron. The correlations between CO and decreased levels of copper and lead approached significance (p=0.056 for both elements). Individuals with CO furthermore displayed significantly lower δ(15)N isotope values, suggesting greater consumption of lower trophic level food resources than those unaffected by CO; δ(13)C and δ(18)O values, in contrast, showed no significant differences. These results suggest that the prevalence of CO may be related to dietary deficiencies. In this case, low iron levels may also signify a diet low in other key vitamins (e.g., B9 and B12), which are known to cause megaloblastic anemia. Copyright © 2016 Elsevier GmbH.

  9. Late 18th to early 19th century sea-level history and inter-seismic behavior along the western Myanmar plate boundary belt recorded by coral microatolls

    Along the western Myanmar plate boundary belt, the Indian-Australian plate is subducting obliquely beneath the Burma micro-plate at a rate of about 23 mm/yr. Although information about the 1762 Arakan earthquake, the only major historical event occurred along this plate boundary belt, has been delineated recently from uplifted coastal features, constraints on the inter-seismic behavior of this belt is still very limited, due to the lack of high resolution instrumental records in the area. Therefore, we utilized coral microatolls to analyze relative sea level history, in order to obtain potential information of land-level change along the western coast of Myanmar. Our sample was collected from northwestern Ramree Island, approximately 80 km away from the trench. Previous studies suggest that the coral was uplifted and killed during a local earthquake event in 1848, and recorded relative sea level history of ~80 years prior to that event. Since the highest level of survival (HLS) of coral microatolls is constrained within a few centimeters of the lowest tide level of the area, the patterns of annual growth bands of the coral microatoll in x-radiograph provide us yearly record of relative sea level, and we used U-Th dating technique to constrain the age of the coral. Our results show that this coral microatoll may have recorded the inter-seismic subsidence of northwestern Ramree Island, punctuated by several climatic events that produced die-down records of the coral growth bands. We hope the data obtained from this coral microatoll, combined with previously reported information of the area, will enable us to further understand the seismic behavior of this major plate boundary belt.

    Although the names of the 18 Century's doctors of Medicine are not unknown, no essay was really written about them and this paper tends to attract attention to the Parisian medical elite of the Ancient System. Pierre Maloet is the example of the doctor of the Monarchical system who as a doctor from Montpellier registered in the Paris Faculty at the beginning of the Century and thanks to his relations with the Guyard-Duchenne managed to be introduced into the Court and the military world. Maloets' careers are good illustrations of penetration into the society and onto the domain of the great varieties of medical exercises. Never they publicly claimed the new ideas of the Century of Enlightment but they embodied its contradictions into the attachment to old structures and the will of innovation.

    Sicily is one of the Italian regions richest in mummified corpses. In addition to the Capuchin Catacombs of Palermo, a true unicum for their exceptional number of individuals, several other mummies collections, dated back to the late Modern Age, are present in many churches, convents and funerary chapels. The Sicilian mummies are the result of a particular treatment, obtained by drying the body in favourable microclimatic conditions without evisceration, a method which permitted equally to achieve a good state of preservation. The mummification was an extremely diffuse phenomenon in Sicily during the 18th and 19th centuries, not only among the privileged classes, but also among the middle-class. Besides the "Cappuccini Catacombs" of Palermo, at present the sites of Sicilian mummies known in scientific literature are restricted to Comiso (Ragusa) and Savoca (Messina); up to now in fact this historical-biological heritage has not been properly surveyed. In this article we present the first results of a survey carried out in the Messina's province during July 2005. The research enabled us to investigate this cultural phenomenon, to document the architectural structures appointed to the mummification process and to enrich the knowledge about the presence of mummified bodies in eastern Sicily during the Modern Age.

    The 18th International Conference on Antiviral Research (ICAR) was held at the Princess Sofia Hotel in Barcelona, Spain, from 11th-14th April, 2005. This is a yearly international meeting sponsored by the International Society for Antiviral Research (ISAR). The current president of ISAR is John A Secrest 3rd of the Southern Research Institute. The scientific programme committee was chaired by John C Drach from the University of Michigan. ISAR was founded in 1987 to exchange prepublication basic, applied and clinical information on the development of antiviral, chemical and biological agents as well as to promote collaborative research. The ISAR has had a major role in the significant advances of the past decade in the reduction of the societal burdens of viral diseases by the focus of ICAR on the discovery and clinical application of antiviral agents. The 18th ICAR was organised as a series of focus presentations on specific viral groups consisting of oral and poster presentations of original research findings. In addition, the conference included plenary speakers, award presentations, a minisymposium on bioterrorism, and a satellite symposium on clinical antiviral drug developments. The size of the conference (> 50 oral and 250 poster presentations) necessitates limitation to the most noteworthy in the judgment of this reviewer. The current membership of the ISAR is approximately 700 with approximately 50% the membership in attendance.

  16. Problema vizual'noj registratsii nablyudenij v opticheskoj astronomii XVII-XVIII vekov %t Problem of visual registration of observations in optical astronomy in the 17th-18th centuries

    NASA Astrophysics Data System (ADS)

    Ivanov, Kostantin V.

    This paper attempts to explain the growth of optical astronomy as a result of more general social and cultural change in European life during the two post-Renaissance centuries. It shows how the introduction of optical instruments into astronomical work was accompanied (and partly conditioned) by a few nonastronomical practices, such as collecting unusual things and their images, producing illusionary effects by means of optical devices, manufacturing pictures that could disturb the common visual perception, etc. The paper draws particular attention to the practices of manipulation with visual images that could help to introduce "illusionary" optical knowledge into making "true" drawings from natural objects, including celestial ones. In this way, the formation of new astronomical language can be understood as closely connected to the explicit formulation of technological instructions and legal rules for making copies from natural objects, as well as the general development of printing production and broadening of the market of printed illustrations. These often not enough co-ordinated practices stipulated the shift of optical astronomy into a significant part of seigniorial culture, where it obtained recognition as an essentially new and elite knowledge, associated with particular technological vigilance. During the transition of European monarchies into the absolutist social order, astronomy, on a level with other court services, assumed a shape of professional occupation supplied with certain monetary salaries, a stable position in official hierarchy, and supreme privileges. This was the way by which astronomy merged with the other natural studies and became one of the publicly recognised scientific disciplines.

    Nevskaya, N. I.

    "Philosophiae Naturalis Principia Mathematica" by I. Newton were published and immediately recognized in England in 1687. However in countries of the continental Europe up to 1744 dominated the Cartesianism. Few newtonians were exposed to persecutions. Under such circumstances in 1724 Peter The Great decided to found an Academy of sciences in Russia. Since in this country there were no scientists, it was decided to invite them from the continental Europe. Two scientists arrived to Russia were newtonians. Other just were graduated from universities and had no hope for scientific work in their native lands. This situation turned out to be rather happy. The newtonians - J. N. Delisle and J. Hermann - trained the youth (D. Bernoulli, L. Euler, F. Ch. Mayer, G. W. Krafft, A. D. Kantemir, G. W. Richmann, M. V. Lomonosov, N. I. Popov, V. K. Trediakovskij, A. D. Krasilnikov etc.). They created the science of Russia and enhanced the doctrine of Newton. Their scientific works were printed in "Commentarii" in Latin. The newspaper "St.-Petersburg sheets" and its appendix, the magazine "Notes on the Sheet" (issued in Russian and German) - published the works of Petersburg Academy of sciences and promoted the Newtonianism. Everyone, who could read in German, used these materials. One of the readers was I. Kant. He relied upon these publications in preparing his lectures at Königsberg University, and then later, in working out the cosmogony theory. The works of J. N. Delisle, L. Euler and A. C. Clairaut on the theory of comets' and planets' movement justified Newtons doctrine. They also forced J. Cassini to accept the doctrine as well. Delisle's papers on the history of astronomy published there are helpful for understanding of the history of development the astronomy. The books of J. F. Weidler "A history of astronomy" (1741) and "Astronomical bibliography" (1755) formed the basis for all histories of astronomy in the XVIII-XIX centuries.

  18. Lightning and Gunpowder in the 18th Century

    On or before June, 1751, Benjamin Franklin and co-workers showed that gunpowder could be ignited by a small electric spark, and subsequently people used gunpowder to enhance the explosions of "thunder houses" to demonstrate that grounded metallic rods would protect model structures against lightning damage. Even before the sentry box and kite experiments proved that thunderclouds are electrified and that lightning is an electrical discharge in 1752, Franklin had hypothesized that a tall, well-grounded conductor might reduce or prevent lightning damage by silently discharging the cloud, and if a discharge did occur, then the tall rod would offer a preferred place for the lightning to strike, and the grounding conductors would guide the current into the ground in a harmless fashion. Over the next 10 years, experience gained through practice showed that grounded rods did indeed protect ordinary structures from lightning damage, but a question remained about the best way to protect gunpowder magazines. In 1762, Franklin recommended a tall "mast not far from it, which may reach 15 or 20 feet above the top of it, with a thick iron rod in one piece fastened to it, pointed at the highest end, and reaching down through the earth till it comes to water," and in 1772 he made a similar recommendation for protecting the British powder magazine at Purfleet. In 1780, Jan Ingenhousz asked Franklin to "communicate to me some short hints, which may occur to you about the most convenient manner of constructing gun powder magazines, the manner of preserving the powder from moisture and securing the building in the best manner from the effects of lightning." In his reply, Franklin detailed a method of protection that is almost perfect, "they should be constructed in the Ground; that the Walls should be lin'd with Lead, the Floor Lead, all 1/4 Inch thick & the Joints well solder'd; the Cover Copper; with a little Scuttle to enter, the whole in the Form of a Canister for Tea. If the Edges of the Cover scuttle fall into a Copper Channel containing Mercury, not the smallest Particle of Air or Moisture can enter to the Powder, even tho' the Walls stood in Water, or the whole was under Water." In 1876, the Scottish physicist, James Clerk Maxwell, made almost exactly the same recommendation for protecting against lightning, a method known today as a "Faraday cage."

    For historians of medicine, the professor Theodor Billroth of the University of Vienna was the leading European surgeon of late nineteenth century and the personification of intervention by organ or body part removal. For social and political historians, he was a German nationalist whose book on medical education heralded the rise of anti-Semitism in the Austrian public sphere. This article brings together and critically reassesses these two hitherto separate accounts to show how, in a period of dramatic social and political change, Viennese surgery split into two camps. One, headed by Billroth, was characterized by an alliance with the German educational model, German nationalism leading to racial anti-Semitism and an experimental approach to the construction of surgical procedure, which heavily relied on the methods of pathological physiology. The other, which followed a long Austrian tradition, stood for a clinically-oriented and strictly organized medical education that catered to an ethnically and socially diverse population and, simultaneously, for an anatomically oriented surgery, largely of the locomotor apparatus. This study shows how, in a major centre of medical education and capital of a multiethnic empire, surgical and national identities were forged together. PMID:18053931

    Since the late 18th century, the Korean traditional medicine trade witnessed a steady growth. There were lots of stores which sold Korean medicinal herbs in Seoul and every major towns had at least one or more stores in Korea, which led to a subsequent growth of people involved in the trade. However, Korean medicine merchants encountered a new environment with the influx of western medicines after the Opening of Ports and the execution of modern medicine policies. Such change of atmosphere led the merchants to seek new breakthroughs. Some of the merchants found the answer in producing and selling patent medicine. The people in the industry had little knowledge of western medicine, so that they had little choice but to combine their experience of Korean medicine with whatever information they had about western counterpart. Such resolution generated a new kind of medicine known as patent medicine. Patent medicine businessmen observed the new medicine policies of the Korean Empire. Some visionary ones even sought to eagerly utilize the trademark system to secure the selling route. The Japanese colonial government strengthened the medicine policies. It revised the legislature and mobilized administrative powers to manage and control the industry. However, such colonial policies in the 1910s implicated certain limits due to its lack of understanding of Korean medicine industry. Also, the colonial government showed poor efforts in introducing modern medicine facilities and systems, so that the ground was set for the patent medicine business to flourish. Patent medicine enjoyed a high turnover. So, the entrepreneurs endeavored to promote the sales in whatever means necessary. The most basic form of advertisement was through the newspaper. Indirect promotion through newspaper articles, issuing medicine flyers, free gift draw, reputation of an influential expert were widely used for its sales. Consequently, patent medicine industry in the 1910s saw a healthy prosperity. One

    The authors present global fields of decadal annual surface temperature anomalies, referred to the period 1951-1980, for each decade from 1881-1890 to 1981-1990 and for 1984-1993. In addition, they show decadal calendar-seasonal anomaly fields for the warm decades 1936-1945 and 1981-1990. The fields are based on sea surface temperature (SST) and land surface air temperature data. The SSTs are corrected for the pre-World War II use of uninsulated sea temperature buckets and incorporate adjusted satellite-based SSTs from 1982 onward. These results extend those published in the 1990 Intergovernmental Panel on Climate Change Scientific Assessment. Despite poor data coverage initially and around the two World Wars the generally cold end of the nineteenth century and start to the twentieth century are confirmed, together with the substantial warming between about 1920 and 1940. Slight cooling of the northern hemisphere took place between the 1950s and the mid-1970s, although slight warming continued south of the equator. Recent warmth has been most marked over the northern continents in winter and spring, but the 1980s were warm almost everywhere apart from Greenland, the northwestern Atlantic and the midlatitude North Pacific. Parts of the middle- to high-latitude southern ocean may also have been cool in the 1980s, but in this area the 1951-1980 climatology is unreliable. The impact of the satellite data is reduced because the record of blended satellite and in situ SST is still too short to yield a climatology from which to calculate representative anomalies reflecting climatic change in the southern ocean. However, the authors propose a method of using existing satellite data in a step toward this target. The maps are condensed into global and hemispheric decadal surface temperature anomalies. The authors show the sensitivity of these estimated anomalies to alternative methods of compositing the spatially incomplete fields. 58 refs., 17 figs., 3 tabs.

    PubMed

    Kim, Dal-Young

    2014-08-01

    In this paper, it was studied how physics affected development of optometry in the United States, from aspects of formation and academization of optometry. It was also revealed that history of optometry was analogous to history of engineering. Optics in the 19th century was divided into electromagnetic study of light and visual optics. Development of the visual optics promoted professionalization of ophthalmology that had already started in the 18th century. The visual optics also stimulated formation of optometry and optometrists body in the late 19th century of the United States. The American optometrists body were originated from opticians who had studied visual optics. Publication of several English academic textbooks on visual optics induced appearance of educated opticians (and jewelers). They acquired a right to do the eye examination in the early 20th century after C. F. Prentice's trial in 1897, evolving into optometrists. The opticians could be considered as craftsmen, and they were divided into (dispensing) opticians and optometrists. Such history of American optometrists body is analogous to that of engineers body in the viewpoints of craftsmen origin and separation from craftsmen. Engineers were also originated from educated craftsmen, but were separated from craftsmen when engineering was built up. Education system and academization of optometry was strongly influenced by physics, too. When college education of optometry started at American universities, it was not belonged to medical school but to physics department. Physics and optics were of great importance in curriculum, and early faculty members were mostly physicists. Optometry was academized in the 1920s by the college education, standardization of curriculum, and formation of the American Academy of Optometry. This is also analogous to history of engineering, which was academized by natural sciences, especially by mathematics and physics. The reason why optometry was academized not by

    Simulations of ozone evolution from 1960 until ~2100 from chemistry climate models (CCMs) that participated in CCMVal-2 are broadly consistent in that stratospheric ozone increases as chlorofluorcarbons decrease and the stratosphere cools (which affects the rate of temperature dependent loss processes), however, details of the projections vary significantly. Differences in the ozone response to specified changes in chlorine containing source gases dominate during the first half of the integrations. For example, from 1980 to 2000, chlorine change is by far the most important cause of ozone change, and the CCMs produce changes in the 60S-60N average column ozone that range between -3 DU and -17 DU. In the second half of the 21st century climate change is primarily responsible for ozone change. By 2080 the CCMs produce changes in the 60S-60N average upper stratospheric ozone column that range from 4 DU to 10 DU. The CCM range of differences is due to differences in both composition and upper stratospheric temperature. Ozone loss processes each have their own temperature sensitivity, and the net sensitivity of ozone to temperature change in each CCM depends on the relative importance of each loss process; this depends on the composition and temperature for the baseline atmosphere. In the lower stratosphere, climate change affects ozone evolution through changes in photochemical reaction rates due to stratospheric cooling and through circulation differences affecting transport of ozone and other trace gases. These are not separable using an approach such as multiple linear regression because changes in circulation and temperature have the same time dependence after accounting for contributions due to chlorine change. Recent attention has focused on similarity of the CCMs in that all predict a speed-up of the Brewer Dobson circulation. However, differences in the magnitude of the speed-up, differences in horizontal mixing and differences in the photochemical response to

    Although alcohol consumption has been described from the earliest times, alcohol abuse has grown significantly since the mid-nineteenth century as a consequence of the industrialization progress. Due to the socio-economic profile of Romania, which was considered to be agrarian, the idea of developing mainly the industry branches belonging to agriculture was considered. Amongst these branches, the production of alcohol appeared to be the most appropriate. The political state leaders from Romania enjoyed the taxes collected from alcohol commercialization, disregarding the costs involved in alcoholism which went far beyond them. PMID:26528038

    Akhenaten was one of Egypt's most controversial pharaohs, in part because of his strange appearance in images produced after he had declared Aten, the Sun-disc, his one-and-only god. Whether these were symbolic representations or realistic ones that indicate a deforming genetic disorder is the subject of continuing debate. The authors present evidence that the bizarre physical features portrayed in these images are not only realistic but were shared by many members of Egypt's 18th Dynasty. The features are best explained by either 2 different familial disorders-the aromatase excess syndrome and the sagittal craniosynostosis syndrome-or a variant of the Antley-Bixler syndrome caused by a novel mutation in one of the genes controlling the P450 enzymes, which regulate steroidogenesis and cranial bone formation.

    Anomalously high summertime temperatures have occurred with increasing frequency since the late 20th century. It is not clear why hot summers are becoming more frequent despite the recent slowdown in the rise in global surface air temperature. To examine factors affecting the historical variation in the frequency of hot summers over the Northern Hemisphere (NH), we conducted three sets of ensemble simulations with an atmospheric general circulation model. The model accurately reproduced interannual variation and long-term increase in the occurrence of hot summers. Decadal variabilities in the Pacific and Atlantic Oceans accounted for 43 ± 27% of the recent increase over the NH middle latitudes. In addition, direct influence of anthropogenic forcing also contributes to increasing the frequency since the late 20th century. The results suggest that the heat extremes can become more frequent in the coming decade even with the persistent slowdown in the global-mean surface warming.

    South Georgia is one of the few landmasses in the Southern Ocean. It provides a crucial geographical datapoint for glacier responses to climate change over different timescales. As part of an ongoing glacier inventory of the island, we are compiling a database of historical glacier photographs. Since the late 19th century, the island has been visited by numerous scientific and survey expeditions, as well as being the land-base for a major whaling industry. Historical photographs of the island are available from the late-19th century, beginning with the 1882-83 German International Polar Year Expedition. Many more exist from the 20th century, notably from the South Georgia Surveys in the 1950s. An assessment of the value of the photographs indicates that spatial coverage is variable, many lack reference features to pinpoint glacier positions and, in the case of smaller glaciers, the presence of snowcover makes it difficult to define the ice edge. Nevertheless, the photographs provide useful corroboration of more advanced glacier positions during the late-19th century and recession of smaller mountain and valley glaciers during the mid-20th century, while larger tidewater and sea-calving glaciers generally remained in relatively advanced positions until the 1980s. Since then, nearly all the glaciers have retreated; some of these retreats have been dramatic and a number of small mountain glaciers have fragmented or disappeared. The response of the glaciers can be related to synoptic-scale warming, particularly since the 1950s, moderated by individual glacier geometry and topography.

    Prior to the 19th century the use of purple dyes for textile coloration was expensive and usually limited to royalty. The discovery of several synthetic purple dyes during the 19th century made the production of purple textiles more affordable and thus more readily available. The identification of the source of the purple coloration is of historical interest. Small yarn samples from four late 19th century silk dresses were analyzed using a combination of thin layer chromatography and surface enhanced Raman spectroscopy, Fourier transform infrared spectroscopy and energy dispersive x-ray spectroscopy. This combination of techniques enabled the analysis of the complex extraction products. While three of the dresses were found to be dyed using methyl violet, the fourth dress was found to be constructed from a warp yarn dyed with methyl violet in the presence of a tannic acid mordant, and a weft yarn dyed with mauve and a tin mordant.

    The subject of this 18th Symposium of ArgoSpine Association was the space of the intervertebral discs. Space of the intervertebral discs must be initially defined anatomically and histologically. A geometrical rebuilding in 3D is possible and must allow a modeling of the intervertebral discs. The physiology of the disc, its nutrition, must be known, in particular that of the center of the disc. The disc constitutes the base of the balance of the rachis, balances which can be only dynamic. The degenerative cascade by the loss of the proteoglycans involves the loss of the biomechanical properties of the disc. The consequences of this degenerative cascade are the base of all the vertebral pathology of origin of the intervertebral discs and even of the posterior articular facets. The origin of the pains and the diagnosis, especially at the lumbar level, are studied by the speakers. Traumatology of the intervertebral discs is the object of a particular chapter. Finally, the average therapeutic ones, that is, decompression of the intervertebral discs, fusion of the intervertebral discs, the recovery of mobility of the intervertebral discs, and the capacity of restoration of space of the intervertebral discs, are studied in detail. The infection of the disc is studied in detail.

    We are delighted to present the Proceedings of the 18th International School on Condensed Matter Physics: Challenges of Nanoscale Science: Theory, Materials, Applications, organized by the Institute of Solid State Physics of the Bulgarian Academy of Sciences and chaired by Professor Alexander G Petrov. On this occasion the School was held in memory of Professor Nikolay Kirov (1943-2013), former Director of the Institute and Chairman between 1991 and 1998. The 18ISCMP was one of several events dedicated to the 145th anniversary of the Bulgarian Academy of Sciences in 2014, and was held in the welcoming Black Sea resort of St. Constantine and Helena near Varna, at the Hotel and Congress Centre Frederic Joliot-Curie. Participants from 16 countries delivered 32 invited lectures, and 71 contributed posters were presented over three lively and well-attended evening sessions. Manuscripts submitted to the Proceedings were refereed in accordance with the guidelines of the Journal of Physics: Conference Series, and we believe the papers published herein testify to the high technical quality and diversity of contributions. A satellite meeting, Transition Metal Oxide Thin Films - Functional Layers in Smart Windows and Water Splitting Devices: Technology and Optoelectronic Properties was held in parallel with the School (http://www.inera.org, 3-6 Sept 2014). This activity, which took place under the FP7-funded project INERA, offered opportunities for crossdisciplinary discussions and exchange of ideas between both sets of participants. As always, a major factor in the success of the 18ISCMP was the social programme, headed by the organized events (Welcome and Farewell Parties) and enhanced in no small measure by a variety of pleasant local restaurants, bars and beaches. We are most grateful to staff of the Journal of Physics: Conference Series for their continued support for the School, this being the third occasion on which the Proceedings have been published under its

    This special issue of Journal of Micromechanics and Microengineering is devoted to the 18th European Workshop on Micromechanics (MME 07), which took place at the University of Minho, Guimarães, Portugal from 16-18 September 2007. Since the first workshop at the University of Twente in 1989 the field of micromechanics has grown substantially and new fields have been added: optics, RF, biomedical, chemistry, and in recent years the emergence of nanotechnology. This year an extensive programme was scheduled with contributions from new materials research to new manufacturing techniques. In addition, the invited speakers presented a review of the state-of-the-art in several main trends in current research, with the focus on micro/nanosystems in the ICT Work Programme in EC FP7. As ever, the two day workshop was attended by delegates from all over Europe, the USA, Brazil, Egypt, Japan and Canada. A total of 96 papers were accepted for presentation and there were a further five keynote presentations. The workshop provides a forum for young researchers to learn about new experimental methods and to enhance their knowledge of the field. This special issue presents a selection of 17 of the best papers from the workshop. The papers highlight fluidic and optical devices, energy scavenging microsystems, neural probe arrays and microtechnology fabrication techniques. All the papers went through the regular reviewing procedure of IOP Publishing, and I am grateful to all the referees for their excellent work. I would also like to extend my thanks to Professor Robert Puers for advice on the final selection of papers and to Ian Forbes of IOP Publishing for managing the entire process. My thanks also go to the editorial staff of Journal of Micromechanics and Microengineering. I believe that this special issue will provide a good overview of the topics presented at the workshop and I hope you enjoy reading it.

    Late 19th century novels provide graphic descriptions of working and living conditions and their impact on population health, in particular the detrimental effects of hunger, poor housing, environmental conditions, hazardous work and poor pay, smoking and alcohol and crime, but also the transformative possibilities of social and political action. The popularity of these novels helped raise the collective conscience of citizens and illuminated the direction for 20th century welfare reforms. Yet many of these problems remain and the pathways to and from poverty are still recognisable today. Although novels are now less central in conveying social information, re‐reading these novels enables us to understand how social and economic circumstances were understood at the time and what led to social and political change.

  16. Priestley's Shadow and Lavoisier's Influence: Electricity and Heat in the Late Eighteenth and Early Nineteenth Centuries

    NASA Astrophysics Data System (ADS)

    Fisher, Amy

    In the late eighteenth century, Joseph Priestley argued that any complete theory of heat also had to explain electrical phenomena, which manifested many similar effects to heat. For example, sparking or heating a sample of trapped air caused a reduction in the volume of air and made the gas toxic to living organisms. Because of the complexity of electrical and thermal phenomena, Antoine Lavoisier did not address electrical action in his published works. Rather, he focused on those effects produced by heating alone. With the success of Lavoisier's caloric theory of heat, natural philosophers and chemists continued to debate the relationship between heat and electricity. In this presentation, I compare and contrast the fate of caloric in early-nineteenth-century electrical studies via the work of two scientists: Humphry Davy in Britain and Robert Hare in America.

    2009-10-01

    The mesmerists explained the phenomena of what was later called hypnosis as the effects of a force called animal magnetism. Both psychologists' and physicians' writings generally create the impression that the magnetic movement disappeared after the mid-19th century. While the concept of animal magnetism declined significantly by the end of the 19th century, it did not disappear completely. Some examples include the work of Hector Durville, Henri Durville, Emile Magnin, and Edmund Shaftesbury. Detailed accounts of the work of Edmund Gurney and Albert de Rochas are presented. Similar to its earlier counterpart, the late mesmeric movement was associated with what today is known as parapsychological phenomena. This association, and the belief that the demise of magnetic theory represents scientific progress, has led many to emphasize a history that is incomplete.

    The 18th Biennial International Conference of the APS Topical Group on Shock Compression of Condensed Matter in conjunction with the 24th Biennial International Conference of the International Association for the Advancement of High Pressure Science & Technology (AIRAPT) was held at the Westin Hotel in Seattle, Washington from 7-12 July, 2013. This is only the second time that these two organizations have held a Joint Conference — the first was 20 years previous (1993) in Colorado Springs, Colorado. Seattle was chosen for this joint conference because of its central location for the world-wide attendees as well as its metropolitan vibrancy. The scientific program consisted of 858 scheduled presentations organized into 23 topical areas and included contributed (537), invited (95), and plenary (6) lectures, as well as two poster sessions with 110 posters each. The scientific focus of the Joint Conference was on fundamental and applied research topics related to the static or dynamic compression of condensed matter. This multidisciplinary field of research encompasses areas of physics, chemistry, materials science, mechanics, geophysics and planetary physics, and applied mathematics. Experimental, computational and theoretical studies all play important roles. The organizers endeavored to intertwine static and dynamic experimental alongside computational and theoretical studies of similar materials in the organization of the sessions. This goal was aided by the addition of three special focus sessions on deep carbon budget, high energy density materials, and dynamic response of materials. 722 scientists and engineers from 25 countries registered at the conference, including 132 students from 12 countries. The attendee countries represented included: Argentina (2), Australia (2), Brazil (3), Canada (25), China (22), Czech Republic (2), France (35), Germany (19), India (6), Israel (21), Italy (10), Japan (49), Netherlands (1), Poland (1), Portugal (2), Russia (26

    Few studies have considered the role of immigration in the rise of gentrification in the late twentieth century. Analysis of U.S. Census and American Community Survey data over 24 years and field surveys of gentrification in low-income neighborhoods across 23 U.S. cities reveal that most gentrifying neighborhoods were "global" in the 1970s or became so over time. An early presence of Asians was positively associated with gentrification; and an early presence of Hispanics was positively associated with gentrification in neighborhoods with substantial shares of blacks and negatively associated with gentrification in cities with high Hispanic growth, where ethnic enclaves were more likely to form. Low-income, predominantly black neighborhoods and neighborhoods that became Asian and Hispanic destinations remained ungentrified despite the growth of gentrification during the late twentieth century. The findings suggest that the rise of immigration after 1965 brought pioneers to many low-income central-city neighborhoods, spurring gentrification in some neighborhoods and forming ethnic enclaves in others.

    2007-01-01

    Historians have shown that fish culturists and anglers enjoyed a mutually beneficial relationship in 19th century North America. Sharing interests in producing and protecting fish for recreation, the two groups supported emerging regimes of fisheries administration and fish culture that privileged angling and game fish species. In Ontario, it has been argued that anglers achieved control of inland fisheries with help from state fish culturist Samuel Wilmot who, as a sportsman, shared anglers' recreational perspective. A closer look at Wilmot and fish culture in late 19th century Ontario, however, reveals a more complex struggle over recreational fisheries administration. I show that game fish culture under Wilmot was subordinated to fish culture programs that supported the Great Lakes commercial fisheries. Indeed, Wilmot resisted anglers' reframing of Ontario's fisheries as a private recreational resource. By the 1890s, however, this position was unpopular with Ontario's anglers and government officials, who demanded greater provincial control over recreational fisheries and fish culture. It was only after Wilmot's retirement in 1895 that game fish culture received higher priority in Ontario with both federal and provincial governments engaging in programs of wild bass transfers. In 1899, Ontario won a share of fisheries jurisdiction and established its first provincial fisheries administration, which laid the basis for more comprehensive programs of game fish culture in the 20th century.

  3. William Keith Brooks and the naturalist's defense of Darwinism in the late-nineteenth century.

    2015-06-01

    William Keith Brooks was an American zoologist at Johns Hopkins University from 1876 until his death in 1908. Over the course of his career, Brooks staunchly defended Darwinism, arguing for the centrality of natural selection in evolutionary theory at a time when alternative theories, such as neo-Lamarckism, grew prominent in American biology. In his book The Law of Heredity (1883), Brooks addressed problems raised by Darwin's theory of pangenesis. In modifying and developing Darwin's pangenesis, Brooks proposed a new theory of heredity that sought to avoid the pitfalls of Darwin's hypothesis. In so doing he strengthened Darwin's theory of natural selection by undermining arguments for the inheritance of acquired characteristics. In later attacks on neo-Lamarckism, Brooks consistently defended Darwin's theory of natural selection on logical grounds, continued to challenge the idea of the inheritance of acquired characteristics, and argued that natural selection best explained a wide range of adaptations. Finally, he critiqued Galton's statistical view of heredity and argued that Galton had resurrected an outmoded typological concept of species, one which Darwin and other naturalists had shown to be incorrect. Brooks's ideas resemble the "biological species concept" of the twentieth century, as developed by evolutionary biologist Ernst Mayr and others. The late-nineteenth century was not a period of total "eclipse" of Darwinism, as biologists and historians have hitherto seen it. Although the "Modern Synthesis" refers to the reconciliation of post-Mendelian genetics with evolution by natural selection, we might adjust our understanding of how the synthesis developed by seeing it as the culmination of a longer discussion that extends back to the late-nineteenth century.

    This special section of Comments on Atomic, Molecular and Optical Physics (CAMOP) in Physica Scripta collects some of the papers that have been presented at the 18th European Conference on Dynamics of Molecular Systems MOLEC 2010 held in September 2010 in Curia, Portugal, as part of a series of biennial MOLEC conferences. This started in 1976 in Trento, Italy, and has continued, visiting 17 cities in 11 countries, namely Denmark, The Netherlands, Israel, France, Italy, Germany, Czech Republic, Spain, United Kingdom, Turkey and Russia. Following the MOLEC tradition, the scientific programme of the Curia meeting focused on experimental and theoretical studies of molecular interactions, collision dynamics, spectroscopy, and related fields. It included invited speakers from 22 countries, who were asked to summarize the problems reported in their presentations with the objective of revealing the current thinking of leading researchers in atomic, molecular and optical physics. It is hoped that their authoritative contributions presented in this CAMOP special section will also appeal to non-specialists through their clear and broad introductions to the field as well as references to the accessible literature. This CAMOP special section comprises ten contributions, which cover theoretical studies on the electronic structure of molecules and clusters as well as dynamics of elastic, inelastic and reactive encounters between atoms, molecules, ions, clusters and surfaces. Specifically, it includes electronic structure calculations using the traditional coupled-cluster method (Barreto et al 028111), the electron-attached equation-of-motion coupled cluster method (Hansen et al 028110), the diffusion Monte Carlo method (López-Durán et al 028107) and the path-integral Monte Carlo method (Barragán et al 028109). The contributions on molecular dynamics include on-the-fly quasi-classical trajectories on a five-atom molecule (Yu 028104), quantum reaction dynamics on triatomics

    YRM logo This volume contains invited and contributed papers from the 18th international conference on 'Microscopy of Semiconducting Materials' held at St Catherine's College, University of Oxford, on 7-11 April 2013. The meeting was organised under the auspices of the Royal Microscopical Society and supported by the Institute of Physics as well as the Materials Research Society of the USA. This conference series deals with recent advances in semiconductor studies carried out by all forms of microscopy, with an emphasis on electron microscopy and scanning probe microscopy with high spatial resolution. This time the meeting was attended by 109 delegates from 17 countries world-wide. We were welcomed by Professor Sir Peter Hirsch, who noted that this was the first of these conferences where Professor Tony Cullis was unable to attend, owing to ill-health. During the meeting a card containing greetings from many of Tony's friends and colleagues was signed, and duly sent to Tony afterwards. As semiconductor devices shrink further new routes for device processing and characterisation need to be developed, and, for the latter, methods that offer sub-nanometre spatial resolution are particularly valuable. The various forms of imaging, diffraction and spectroscopy available in modern microscopes are powerful tools for studying the microstructure, electronic structure, chemistry and also electric fields in semiconducting materials. Recent advances in instrumentation, from lens aberration correction in both TEM and STEM instruments, to the development of a wide range of scanning probe techniques, as well as new methods of signal quantification have been presented at this conference. Two topics that have at this meeting again highlighted the interesting contributions of aberration corrected transmission electron microscopy were: contrast quantification of annular dark-field STEM images in terms of chemical composition (Z-contrast), sample thickness and strain, and the study of

  6. In Referees We Trust? Controversies over Grant Peer Review in the Late Twentieth Century

    While many accounts of external refereeing assume that it has been a consistent part of science since the seventeenth century, the practice developed far more slowly and haphazardly than many observers realize, and it was not until after the Second World War that ''peer review'' became considered an essential part of scientific publishing or grant-making. This talk will explore refereeing procedures at American grant-giving organizations in the twentieth century, focusing especially on the National Science Foundation and the National Institutes of Health. The creators of the NSF and the NIH put refereeing systems in place at their foundation. However, the form and function of these systems differed from modern ''peer review'' in several important ways. At the NSF the initial purpose of the referee process was to advise the NSF program directors, not to dictate funding decisions. At the NIH, small ''study sections'' devoted to particular subjects made recommendations to the NIH leadership, which rendered final judgments. However, beginning in the 1960s a series of controversies about NIH and NSF grants placed refereeing procedures at these organizations under more intense scrutiny. These debates culminated in six days of Special Oversight Hearings into the NSF's peer review process in the summer of 1975. Following the hearings, both the NSF and NIH reformed their review processes to place more emphasis on referees' opinions about grant proposals, making peer review increasingly responsible for decision-making. These controversies illustrate that refereeing continued to undergo significant changes in form and purpose throughout the twentieth century, and further suggest that both the scientific community and the public placed increased emphasis on the role of the referee during the late twentieth century.

  7. Medical confidentiality in the late nineteenth and early twentieth centuries: an Anglo-German comparison1

    2012-01-01

    Summary Professional secrecy of doctors became an issue of considerable medico-legal and political debate in the late nineteenth and early twentieth centuries in both Germany and England, although the legal preconditions for this debate were quite different in the two countries. While in Germany medical confidentiality was a legal obligation and granted in court, no such statutory recognition of doctors’ professional secrecy existed in England. This paper is a comparative analysis of medical secrecy in three key areas - divorce trials, venereal disease and abortion - in both countries. Based on sources from the period between c.1870 and 1939, our paper shows how doctors tried to define the scope of professional secrecy as an integral part of their professional honour in relation to important matters of public health.

  8. Medicine, belief, witchcraft and demonic possession in late seventeenth-century Ulster.

    Ireland's only published witchcraft pamphlet, written by Daniel Higgs, The Wonderful and True Relation of the Bewitching of a Young Girle in Ireland, What Ways she was Tormented, and a Receipt of the Ointment that she was Cured with (1699), works within the confines of late seventeenth-century demonology, while upholding the patriarchy of the fledgling Protestant Ascendancy. More importantly, it provides rare insight into early modern Protestant witchcraft beliefs, highlights the limits of contemporary medical care and provision and details the pathways of self-medication people resorted to. Higgs' method of promoting self-medication as a cure to bewitchment and demonic possession was based on a remedy described in an obscure Renaissance magical text. To promote his 'cure' the pamphlet included a particularly vitriolic critique of the established Irish medical profession, as self-regarding and incompetent witchcraft deniers. This article uses Higgs' pamphlet to explore the limits to/of medical knowledge in early modern Ireland and Europe.

    While health education in late nineteenth-century Britain could be beneficial for every household, it was particularly so where district nurses understood family circumstances and adapted knowledge to individual needs. During this period sick room cookery training and lectures on hygiene and dietetics became standard for nurses--especially following the reforms of Matron Eva Lückes at the London Hospital. Because understanding about health was not widespread in society, due to the living conditions and poverty of so many patients, and because doctors had few opportunities to convey such knowledge, the active support of nurses in the community proved to be essential for translating professional knowledge into words commonly understood. By demonstrating cooking and other health-related skills in the homes of the poor, nurses played an important part in improving the nation's health.

    In this study we analyze the organization of natural science teaching within the Argentinian school context starting with teaching practices and material support in the late XIX century. By that time, school staff and teachers fostered modernization and nationalization of teaching by using collections with national issues and the foundation of museums within the schools. In particular, we examine the official debates over the mineralogical collections offered for sale by the naturalist Enrique de Carlés, and the "school museums" by professors Pedro Scalabrini and Guillermo Navarro. These account for the tension between searching for modern didactic materials associated with foreign models, and the importance of counting on elements that represented the country nature and industry.

  11. Projection of American dustiness in the late 21(st) century due to climate change.

    Climate models project rising drought risks over the southwestern and central U.S. in the twenty-first century due to increasing greenhouse gases. The projected drier regions largely overlay the major dust sources in the United States. However, whether dust activity in U.S. will increase in the future is not clear, due to the large uncertainty in dust modeling. This study found that changes of dust activity in the U.S. in the recent decade are largely associated with the variations of precipitation, soil bareness, and surface winds speed. Using multi-model output under the Representative Concentration Pathways 8.5 scenario, we project that climate change will increase dust activity in the southern Great Plains from spring to fall in the late half of the twenty-first century - largely due to reduced precipitation, enhanced land surface bareness, and increased surface wind speed. Over the northern Great Plains, less dusty days are expected in spring due to increased precipitation and reduced bareness. Given the large negative economic and societal consequences of severe dust storms, this study complements the multi-model projection on future dust variations and may help improve risk management and resource planning.

    George Cheyne was a well-known physician with a practice in Bath and London. He was a fat, jovial Scotsman weighing 32 stone at one time and with a great sense of humour who could be classed as one of the characters of the period. His health suffered seriously from eating and drinking too much in taverns with his 'bottle companions' when young, and he spent the rest of his life writing books for the public to help them avoid the problems he had experienced, with a particular emphasis on diet and nervous disorders. His book entitled An Essay on Health and Long Life had particular success. Although often lampooned, he had many famous patients including Beau Nash, Samuel Richardson, The Countess of Huntingdon and Catherine Walpole, the eldest daughter of the Prime Minister Robert Walpole. He was a skilled and caring doctor and health educator, and has been said to have established the agenda for psychiatric epidemiology.

    The "gin epidemic" of 1720 to 1751 in England was the first time that government intervened in a systematic fashion to regulate and control sales of alcohol. The epidemic therefore provides an opportunity to gauge the effects of multiple legislative interventions over time. Toward that end, we employed time series analysis in conjunction with qualitative methodologies to test the interplay of multiple independent variables, including real wages and taxes, on the consumption of distilled spirits from 1700 through 1771. The results showed that each of the 3 major gin acts was successful in the short term only, consistent with the state's limited resources for enforcement at the local level, and that in each instance consumption actually increased shortly thereafter. This was true even of the Gin Act of 1751, which, contrary to the assumptions of contemporaries and many historians, succeeded by accident rather than by design. The results also suggest that the epidemic followed the inverse U-shaped trajectory of more recent drug scares and that consumption declined only after the more deleterious effects of distilled spirits had been experienced by large numbers of people.

    As part of an interdisciplinary research program on Alpine populations, we studied the biodemographic evolution of two populations of the Dauphiné in the period 1690-1799. We analyzed several indexes derived from surname analysis to infer the genetic structure of the populations. Although situated in the same area of the Dauphiné, the two communities of Vallouise and Chiomonte had different biodemographic characteristics. Vallouise was heavily populated but genetically homogeneous, whereas Chiomonte was less populated but more heterogeneous. The two districts also differed in geographic position: Vallouise was a glacier-enclosed valley that did not attract new inhabitants; Chiomonte was situated in an open valley served by important roads and thus was able to attract many new inhabitants. The demographic differences between the two populations explain the differences in genetic structure. The index of isonymous relationship (R(i)) being different from 0 is due to the rare marriages between members of the two populations. Because R(i) is based on surnames, which are mostly polyphyletic, it can overestimate the genetic relationships between the populations, as in the case of consanguinity assessed by matrimonial isonymy.

  16. Gross enamel hypoplasia in molars from subadults in a 16th-18th century London graveyard.

    2007-07-01

    Dental Enamel Hypoplasia has long been used as a common nonspecific stress indicator in teeth from archaeological samples. Most researchers report relatively minor linear and pitted hypoplastic defects on tooth crown surfaces. In this work we report a high prevalence and early age of onset of extensive enamel defects in deciduous and permanent molars in the subadults from the post-medieval cemetery of Broadgate, east central London. Analysis of the dentition of all 45 subadults from the cemetery, using both macroscopic and microscopic methods, reveals disturbed cusp patterns and pitted, abnormal and arrested enamel formation. Forty-one individuals from this group (93.2%) showed some evidence of enamel hypoplasia, 28 of them showing moderate or extensive lesions of molars, deciduous or permanent (63.6% of the sample). Scanning Electron Microscope images reveal many molars with grossly deformed cuspal architecture, multiple extra cusps and large areas of exposed Tomes' process pits, where the ameloblasts have abruptly ceased matrix production, well before normal completion. This indented, rough and poorly mineralized surface facilitates both bacterial adhesion and tooth wear, and when such teeth erupt fully into the mouth they are likely to wear and decay rapidly. We suggest that this complex combination of pitted and plane-form lesions, combined with disruption of cusp pattern and the formation of multiple small cusps, should henceforth be identified as "Cuspal Enamel Hypoplasia."

    Within the "Oran-Tlemcen" railway line realization project (159 km), several bridges were built by the Railroads Algerian West Company. 7 km from the east of Tlemcen city, this railway line must cross a very broken mountainous collar, that's why the French engineer "Gustave Eiffel" was solicited to construct a 68 m length bridge. In 1890, an arch steel truss bridge was realized. The bridge presents 300 m of apron curvature radius and, currently, is considered as one of the most important monuments of the Algerian historical heritage. Considering the age of the bridge and the evolution of the railway loads in time, it was essential to check the good behavior of the studied structure. For that, analyses to verify the physical and mechanical properties of the growth iron members are made. A finite element model of the bridge was built and numerical simulations were drawn. The structural vibration conducted analysis permit to understand the behavior of this particular structure, then to evaluate (in detail) the rate of the structure fatigue.

    Johann Friedrich Glaser rose from an executioner's family to the position of a town physician in Suhl. The contribution concentrates on the importance of this position for Glaser. It first looks at the position of town physicians in Suhl. They possessed due to certain historical circumstances several duties and rights. They enjoyed a remarkably high standing in the town society which made the position especially attractive for Glaser as a road to social acceptance. His interaction with the medical administration in Dresden (Suhl belonged to the jurisdiction of Electoral Saxony) further enhanced his possibilities to interact with local and territorial spheres. Altogether, Glaser's official functions gained importance over his role as a (medical) scientist, because they offered him the best way to gain social and cultural prestige.

    In this paper, we analyse the aims, contents and impact of Seabra’s two-volume textbook - Elementos de Chimica ( Elements of Chemistry) - published in 1788 and 1790. Seabra’s Elements of Chemistry does not conform to the characteristics usually ascribed to textbooks by traditional historiography, and in particular to textbooks published in the peripheries. Marking the arrival of the new chemistry in Portugal, in a period in which many still resisted Lavoisier’s chemistry, this textbook was a state of the art account written in Portuguese, interspersed with critical evaluations, original comments and novel contributions. Despite being the only Portuguese chemistry textbook written during this period, it had hardly any readers, even among its natural audience at the University of Coimbra.

    To describe the function of New Spain's Boards of Health, which were created in times of emergencies as in epidemic diseases or natural catastrophes. Most of the information comes from primary sources, such as the rules, orders and reports of the Boards of Health. Whenever an epidemic disease appeared in New Spain, there were not enough physicians, hospitals or medical services to fulfill the needs of society. The response was the creation of Boards of Health that functioned as charitable groups. Their purpose was to provide food, clothing and medical support to the sick, by collecting donations and distributing them among the needed, and also by assigning physicians to specific geographical sectors within cities. The presence of Boards of Health was useful to fight epidemics in New Spain allowing the team work not only among physicians, but also among parish priests and neighborhood to offer assistance and help to sick people as medical, welfare work and soulful support.

    The complement system has been studied for about 120 years. Progress in defining this large and complex system has been dependent on the research technologies available, but since the introduction of protein chromatography, electrophoresis, and antibody-based assay methods in the 1950s and 60s, and sequencing of proteins and DNA in the 70s and 80s, there has been very rapid accumulation of data. With more recent improvements in 3D structure determination (nmr and X-ray crystallography), the structures of most of the complement proteins have now been solved. Complement research since 1990 has been greatly stimulated by the discoveries of the multiple proteins in the lectin pathway, the strong association of Factor H, C3, Factor B allelic variants with adult macular degeneration and atypical haemolytic uremic syndrome, and the introduction of the anti-C5 monoclonal antibody as a therapy for paroxysmal nocturnal hemoglobinuria and atypical haemolytic uremic syndrome. Potential new roles for complement in tissue development and the search for novel therapeutics suggest a very active future for complement research.

    Catalogue of Flamsteed (flamstee.dat): John Flamsteed (1646-1719) was the first astronomer in charge of Greenwich Observatory. His stellar catalogue (Flamsteed 1725) was built on observations from 1675 to 1683 with a 6-feet radius sextant mounted on an axis parallel to the polar axis of the Earth, then from 1683 to 1719 with a mural circle with a radius of 79.5 inches (2m). 220 stars over 3925. Catalogue of Romer (romer.dat): Ole (or Olaus) Romer (1644-1710) is principally known for his 1676 discovery of the finite velocity of light, a discovery that he shared with Jean-Dominique Cassini. After a long stay in Paris, he returned to Copenhagen in 1681 and was appointed professor of astronomy at the University. The observatory and all the observations were destroyed in the great Copenhagen fire of 1728, with the exception of observations of 88 stars obtained during three observing nights, from 20 to 23 October 1706. La Caille's catalogue of fundamental stars (lacaifun.dat): Nicolas-Louis La Caille (or Lacaille, or de la Caille, 1713-1762) was a French astronomer who is remembered principally for his survey of the southern sky, where he introduced 14 new constellations that are still in use today. Before leaving for the Cape of Good Hope in 1750, he started a catalogue of the 400 brightest stars of both hemispheres, which he completed during his stays in Cape Town and in the Mauritius island, then after his return to Paris in 1754. He reduced the observations himself, including for the first time corrections for aberration and nutation, and published them with details of the observations and reductions (La Caille 1757). Bailly's adaptation of La Caille's catalogue of fundamental stars (bailly.dat): After the death of La Caille, Jean-Sylvain Bailly published a catalogue of the brighest stars of both hemispheres for the equinox B1750.0 in Ephemerides for 10 year from 1765 to 1775 (Anonymous (Bailly) 1763, p. lvii-lxiv). This catalogue obviously derives from the catalogue named lacaillefund.dat. La Caille's complete survey of the southern sky (lacaisur.dat): During his stay in Cape Town in 1751-1752, La Caille made the first systematic survey of the sky ever, in the modern sense. 244 stars over 9766. La Caille's catalogue of zodiacal stars (lacaizod.dat): When La Caille returned from his southern expedition in 1754, he undertook the construction of a catalogue of zodiacal stars. Mayer's zodiacal catalogue (mayer.dat): At exactly the same time as La Caille, Tobias Mayer (1723-1762) in Gottingen undertook a similar catalogue of zodiacal stars, using a 6-feet radius mural quadrant made by John Bird (1709-1776). 200 stars over 998. Bradley's stellar catalogue (bradley.dat): James Bradley (1693-1762) is famous for his discovery of aberration and nutation. From 1750 to his death in 1762, he built a large stellar catalogue, from observations first with an old mural sector and after 1753 with the Bird 8-ft mural sector located in Greenwich, where it 215 stars over 3220. Piazzi's stellar catalogue (piazzi.dat): Giuseppe Piazzi (1746-1846) built a large catalogue containing 7646 stars from 1792 to 1813, observed in Palermo with an altazimuthal circle of Jesse Ramsden (1735-1800) can still be seen. 202 stars over 7646. Lalande's stellar catalogue (lalande.dat): L'Histoire celeste francaise de Lalande (Lalande 1801), which contains the unreduced observations of approximately 40,000 stars, is the first very large stellar catalogue. 198 stars over ~45000.

    "Charity books" were books containing formulas of remedies, which were easy to prepare and not too expensive. Their purpose was to cure poor people who had not enough money to have access to official Medicine or who lived too far away from medicine doctors and apothecaries. They were then useful for charitable people such as country priests or charitable Ladies. Great Theriacs were very expensive and too difficult to prepare to be described in this kind of books for non-professional people. Simplified formulas were then proposed. They contained much less products and were quite cheaper. Some of these medicines are described in this article.

    Circumcision has always been regarded as both an important social event and a milestone of a young man's life in Turkish culture, especially in the Ottoman period. Herein we study an exceptional circumcision festivity which lasted 15 days in the early autumn of the year 1720, for the 4 princes of Sultan III Ahmed, some sons of two high-ranking Ottoman officials and thousands of male children of poor citizens of Istanbul as representing the beneficent of the Sultan. All the organizations of the Empire participated in this huge event, including many shows and a feast, and the preparations were initiated months before. Traditionally, this kind of important social event of Ottoman culture had been described in a literary manner, and Surname-i Vehbi was the special name for the book of this circumcision festivity with 137 colored paintings and a total of 175 pages. The original of this work, which is in the library of Topkapi Palace Museum in Istanbul, was written by Vehbi and illustrated by Levni. The importance of this antique book is that it is the last important example of the illustrated festivity books of Ottoman literature.

    Gigantism results when a growth hormone-secreting pituitary adenoma is present before epiphyseal fusion. In 1909, when Harvey Cushing examined the skeleton of an Irish patient who lived from 1761 to 1783, he noted an enlarged pituitary fossa. We extracted DNA from the patient's teeth and identified a germline mutation in the aryl hydrocarbon-interacting protein gene (AIP). Four contemporary Northern Irish families who presented with gigantism, acromegaly, or prolactinoma have the same mutation and haplotype associated with the mutated gene. Using coalescent theory, we infer that these persons share a common ancestor who lived about 57 to 66 generations earlier.

    The frena of the tongue and lip are normal structures of the buccal cavity, and surgical resection is only necessary in cases of hypertrophy. This article looks at medical texts of the Early Modern Era to analyze the origins and quality of our knowledge on this topic and examine any therapeutic measures proposed. This review shows that while the indications for carrying out tongue frenectomy are very similar to those today (speech and breastfeeding difficulties), those for carrying out a lip frenectomy are very different. Interestingly, apart from purely surgical or medicinal treatments, some authors indicated the need to complement such treatment with educational intervention and what can only be called basic speech therapy.

  13. Healing with animals in the Levant from the 10th to the 18th century

    2006-01-01

    Animals and products derived from different organs of their bodies have constituted part of the inventory of medicinal substances used in various cultures since ancient times. The article reviews the history of healing with animals in the Levant (The Land of Israel and parts of present-day Syria, Lebanon, and Jordan, defined by the Muslims in the Middle Ages as Bilad al-Sham) in the medieval and early Ottoman periods. Intensive research into the phenomenon of zootherapy in the medieval and early Ottoman Levant has yielded forty-eight substances of animal origin that were used medicinally. The vast majority of these substances were local and relatively easy to obtain. Most of the substances were domestic (honey, wax, silkworm, etc.), others were part of the local wildlife (adder, cuttle fish, flycatcher, firefly, frog, triton, scorpion, etc.), part of the usual medieval household (milk, egg, cheese, lamb, etc.), or parasites (louse, mouse, stinkbug, etc.). Fewer substances were not local but exotic, and therefore rare and expensive (beaver testicles, musk oil, coral, ambergris, etc.). The range of symptoms that the substances of animal origin were used to treat was extensive and included most of the known diseases and maladies of that era: mainly hemorrhoids, burns, impotence, wounds, and skin, eye, and stomach diseases. Changes in the moral outlook of modern societies caused the use of several substances of animal origin to cease in the course of history. These include mummy, silkworm, stinkbug, scarabees, snail, scorpion, and triton. PMID:16504024

    The views of femininity and the attempts to standardise it, developed in the 18th century in philosophy, education, literature, theology, anthropology and medicine, have led to intense research in the last years. Such research normally starts with the Enlightenment debates in the second half of the 18th century, but there are interesting sources which allow the tracing of a development over a longer period and which had a wider contemporary readership than any scholarly treatise. These are the popular beauty manuals, which in the German-speaking area started to appear more frequently from the late 17th century on, composed chiefly by physicians who thereby hoped to profit from the growing book and healthcare market. The present article considers the approaches of physicians to female beauty, with special reference to the discontinuities caused by the Enlightenment.

  3. The lost origin of chemical ecology in the late 19th century

    2008-01-01

    The origin of plant chemical ecology generally dates to the late 1950s, when evolutionary entomologists recognized the essential role of plant secondary metabolites in plant–insect interactions and suggested that plant chemical diversity evolved under the selection pressure of herbivory. However, similar ideas had already flourished for a short period during the second half of the 19th century but were largely forgotten by the turn of the century. This article presents the observations and studies of three protagonists of chemical ecology: Anton Kerner von Marilaun (1831–1898, Innsbruck, Austria, and Vienna, Austria), who mainly studied the impact of geological, climatic, and biotic factors on plant distribution and survival; Léo Errera (1858–1906, Brussels, Belgium), a plant physiologist who analyzed the localization of alkaloids in plant cells and tissues histochemically; and Ernst Stahl (1848–1919, Jena, Germany), likely the first experimental ecologist and who performed feeding studies with snails and slugs that demonstrated the essential role of secondary metabolites in plant protection against herbivores. All three, particularly Stahl, suggested that these “chemical defensive means” evolved in response to the relentless selection pressure of the heterotrophic community that surrounds plants. Although convincingly supported by observations and experiments, these ideas were forgotten until recently. Now, more than 100 years later, molecular analysis of the genes that control secondary metabolite production underscores just how correct Kerner von Marilaun, Errera, and, particularly, Stahl were in their view. Why their ideas were lost is likely a result of the adamant rejection of all things “teleological” by the physiologists who dominated biological research at the time. PMID:18218780

  5. The fire ant wars. Nature and science in the pesticide controversies of the late twentieth century.

    PubMed

    Buhs, Joshua Blu

    2002-09-01

    This essay uses an approach borrowed from environmental history to investigate the interaction of science and nature in a late twentieth-century controversy. This debate, over the proper response to fire ants that had been imported into the American South accidentally and then spread across the region, pitted Rachel Carson and loosely federated groups of conservationists, scientists, and citizens against the U.S. Department of Agriculture. The analysis falls into three sections: an examination of the natural history of the ants; an examination of the views of the competing factions; and an examination of how those views, transformed into action, affected the natural world. Both sides saw the ants in terms of a constellation of beliefs about the relationship between nature, science, and democracy. As various ideas were put into play, they interacted with the natural history of the insects in unexpected ways--and with consequences for the cultural authority of the antagonists. Combining insights from the history of science and environmental history helps explain how scientists gain and lose cultural authority and, more fundamentally, allows for an examination of how nature can be integrated into the history of science.

    2012-10-01

    The historiography of medicine in South Asia often assumes the presence of preordained, homogenous, coherent and clearly-bound medical systems. They also tend to take the existence of a medical 'mainstream' for granted. This article argues that the idea of an 'orthodox', 'mainstream' named allopathy and one of its 'alternatives' homoeopathy were co-produced in Bengal. It emphasises the role of the supposed 'fringe', ie. homoeopathy, in identifying and organising the 'orthodoxy' of the time. The shared market for medicine and print provided a crucial platform where such binary identities such as 'homoeopaths' and 'allopaths' were constituted and reinforced. This article focuses on a range of polemical writings by physicians in the Bengali print market since the 1860s. Published mostly in late nineteenth-century popular medical journals, these concerned the nature, definition and scope of 'scientific' medicine. The article highlights these published disputes and critical correspondence among physicians as instrumental in simultaneously shaping the categories 'allopathy' and 'homoeopathy' in Bengali print. It unravels how contemporary understandings of race, culture and nationalism informed these medical discussions. It further explores the status of these medical contestations, often self-consciously termed 'debates', as an essential contemporary trope in discussing 'science' in the vernacular.

    PubMed

    2014-12-01

    During the late 20(th) century numerical rating scales became central to the diagnosis of dementia and helped transform attitudes about its causes and prevalence. Concentrating largely on the development and use of the Blessed Dementia Scale, I argue that rating scales served professional ends during the 1960s and 1970s. They helped old age psychiatrists establish jurisdiction over conditions such as dementia and present their field as a vital component of the welfare state, where they argued that 'reliable modes of diagnosis' were vital to the allocation of resources. I show how these arguments appealed to politicians, funding bodies and patient groups, who agreed that dementia was a distinct disease and claimed research on its causes and prevention should be designated 'top priority'. But I also show that worries about the replacement of clinical acumen with technical and depersonalized methods, which could conceivably be applied by anyone, led psychiatrists to stress that rating scales had their limits and could be used only by trained experts.

    The article considers activity of municipal self-governments of Russia concerning support of sanitary epidemiological well-being of cities in the late XIX--early XX centuries. The acuteness of problem of sanitary conditions of urban settlements particularly became visible in post-reform period due to increasing of number of urban population, alteration of setup and rhythm of life in cities, appearance of new forms of worker's daily chores. Al this, against the background of underdevelopment of communal sphere aggravated epidemiological situation in cities. The impulse to improvement and development of sanitary control was made by the city regulations of 1870 presenting to town authorities the right to deal with sanitary issues. The significant input into improvement of cities was made first of all at the expense of construction of water supplies and sewerage and support of sanitary control of these spheres of municipal economy. Under town councils of many cities the sanitary commissions were organized to support permanent sanitary control in town. The development of town sanitation followed the way of specialization. The housing and communal, trade and food, school and sanitary and sanitary and veterinary control were organized.

  10. Navigating oceans and cultures: Polynesian and European navigation systems in the late eighteenth century

    2012-05-01

    Significant differences in the rotation of the celestial dome between the tropical and temperate zones did not stop the peoples of either the tropical Pacific or temperate Europe from using geocentric astronomy to guide exploration of the oceans. Although the differences in the night sky contributed to differences between the Pacific Island and European systems for navigation at sea, the two navigation systems exhibit substantial similarities. Both systems define positions on the surface of the Earth using two coordinates that vary at right angles to each other and use stars, and to a lesser extent the sun, to determine directions. This essay explores similarities and differences in the use of geocentric astronomy for navigation at sea by the peoples of Polynesia and Europe in the late eighteenth century. Captain Cook's orders to discover the unknown southern continent after observing the transit of Venus combined with differences in language and culture to obscure the deeper similarities between the navigation systems used by Cook and the Polynesians. Although it was a further 200 years before anthropologists studied Pacific navigation, collaborations in voyaging with communities in Oceania demonstrated the effectiveness of Pacific navigation systems, revived interest in traditional voyaging in island communities around the Pacific, and potentially open the way for further collaborations in other areas.

    2000-01-01

    A prominent feature of late nineteenth-century psychology was its intense preoccupation with precision. Precision was at once an ideal and an argument: the quest for precision helped psychology to establish its status as a mature science, sharing a characteristic concern with the natural sciences. We will analyse how psychologists set out to produce precision in 'mental chronometry', the measurement of the duration of psychological processes. In his Leipzig laboratory, Wundt inaugurated an elaborate research programme on mental chronometry. We will look at the problem of calibration of experimental apparatus and will describe the intricate material, literary, and social technologies involved in the manufacture of precision. First, we shall discuss some of the technical problems involved in the measurement of ever shorter time-spans. Next, the Cattell-Berger experiments will help us to argue against the received view that all the precision went into the hardware, and practically none into the social organization of experimentation. Experimenters made deliberate efforts to bring themselves and their subjects under a regime of control and calibration similar to that which reigned over the experimental machinery. In Leipzig psychology, the particular blend of material and social technology resulted in a specific object of study: the generalized mind. We will then show that the distribution of precision in experimental psychology outside Leipzig demanded a concerted effort of instruments, texts, and people. It will appear that the forceful attempts to produce precision and uniformity had some rather paradoxical consequences.

    Documental sources provided information to historically reconstruct the relationship among precipitation, drought and floods during the last 50 years of the 16th century in the Jarama-Tajo river system. The study area is located in the central Iberian Peninsula in the autonomous region of Madrid and is associated with a continental Mediterranean climate Periodic flooding of the fluvial shore and channel bed displacement in the Jarama-Tajo system conditioned land use during the historical period chosen for this study. Centuries ago, land use was well adapted to this river system and produced water intensive crops and pastureland despite the area’s relatively arid continental climate. Today, the river dynamics that once characterized the area, and are referred to in historical documents, have been replaced by permanent channels with stable courses on the flood plain due to the construction of regulating reservoirs and widespread gravel extraction. The data culled from the historical documents consulted for this study made it possible to detect and characterize the floods, and to relate them to yearly or seasonal variations in precipitation and temperature in the late 16th century. As a result, it was possible to define the interaction and time span between precipitation, droughts and floods; to provide a more accurate characterization of the climate at the end of the 16th century in accordance with earlier publications on the topic; and to define the fluvial dynamics of the rivers that form this system. These dynamics, although typical of Mediterranean regions, are often difficult to characterize since alterations in the area make it impossible to obtain direct data. The administrative records of royal estates located south of Madrid contained the most solid data, and was enhanced by accounts of incidents occurring in property located in groves or flood plains in the study area that was managed by religious orders or townships. The archives consulted included the

    Following the petroleum price and supply disruptions of 1973, the U.S. government began a substantial program to fund the development of alternative fuels. Direct coal liquefaction was one of the potential routes to alternative fuels. The direct coal liquefaction program was funded at substantial levels through 1982, and at much lower levels thereafter. Those processes that were of most interest during this period were designed to produce primarily distillate fuels. By 1999, U.S. government funding for the development of direct coal liquefaction ended. Now that the end of this campaign has arrived, it is appropriate to summarize the process learnings derived from it. This report is a summary of the process learnings derived from the DOE direct coal liquefaction process development campaign of the late twentieth century. The report concentrates on those process development programs that were designed to produce primarily distillate fuels and were largely funded by DOE and its predecessors in response to the petroleum supply and price disruptions of the 1970s. The report is structured as chapters written by different authors on most of the major individual DOE-funded process development programs. The focus of the report is process learnings, as opposed to, say, fundamental coal liquefaction science or equipment design. As detailed in the overview (Chapter 2), DOE's direct coal liquefaction campaign made substantial progress in improving the process yields and the quality of the distillate product. Much of the progress was made after termination by 1983 of the major demonstration programs of the ''first generation'' (SRC-II, H-Coal, EDS) processes.

  16. Coral Records of Late 20th Century Warming and Freshening in the Central Tropical Pacific

    NASA Astrophysics Data System (ADS)

    2007-12-01

    Tropical Pacific climate variability strongly impacts global temperature and rainfall patterns. The evolution of tropical Pacific climate under anthropogenic greenhouse warming is unclear, observational and modeling studies support both a strengthening (Cane et al.,1997) and a weakening (Vecchi et al.,2006) of the tropical Pacific zonal sea-surface temperature (SST) gradient. Corals from the central tropical Pacific (CTP) have provided monthly-resolved climate proxy records that contain late 20th century trends toward more negative oxygen isotopic (d18O) values, suggesting that regional warming and/or freshening has occurred over the last several decades (Urban et al.,2000; Cobb et al.,2001). It is important to identify the physical mechanisms that underlie these trends in order to better predict low-frequency changes in tropical Pacific climate over the next decades. One potential mechanism involves a reduction in the tropical Pacific zonal SST gradient, which would warm the CTP by reducing upwelling while increasing rainfall (thereby decreasing salinity). On the other hand, warming might have occurred absent any change in the zonal SST gradient, and the freshening may signal changes in the location and/or intensity of the Inter-Tropical Convergence Zone (ITCZ). Here we apply d18O and Sr/Ca proxies to modern corals from Palmyra, Fanning and Christmas Islands (2-6°N,157-162°W) in order to reconstruct SST and sea-surface salinity (SSS) over the last several decades. While coral d18O changes in SST and/or the d18O of seawater (d18Osw, which is linearly related to salinity in this region), coral Sr/Ca is mainly controlled by SST. When used together, these two proxies allow us to quantify recent climate trends in the CTP with respect to SST and SSS, particularly because Palmyra, Fanning and Christmas span strong gradients in SST and SSS. The islands are aligned in a NW-SE fashion, such that Christmas (2°N) is bathed by the South Equatorial Current and dominated by

    Hydraulics is an engineering specialty and largely neglected as a topic in physics teaching. But the history of hydraulics from the Renaissance to the Baroque, merits our attention because hydraulics was then more broadly conceived as a practical and theoretical science; it served as a constant bone of contention for mechanics and mathematics; its obvious practical importance from raising water in mines to the playful fountains in royal gardens illustrates the social role of science like few others do. The playful character of historic hydraulics problems makes it also an appealing topic for modern science education.

    2015-07-29

    This study performs high-spatial-resolution (12 km) Weather Research and Forecasting (WRF) simulations over a very large domain (7200 km × 6180 km, covering much of North America) to explore changes in mean and extreme precipitation in the mid and late 21st century under Representative Concentration Pathways 4.5 (RCP 4.5) and 8.5 (RCP 8.5). We evaluate WRF model performance for a historical simulation and future projections, applying the Community Climate System Model version 4 (CCSM4) as initial and boundary conditions with and without a bias correction. WRF simulations using boundary and initial conditions from both versions of CCSM4 show smaller biases versus evaluation data sets than does CCSM4 over western North America. WRF simulations also improve spatial details of precipitation over much of North America. However, driving the WRF with the bias-corrected CCSM4 does not always reduce the bias. WRF-projected changes in precipitation include decreasing intensity over the southwestern United States, increasing intensity over the eastern United States and most of Canada, and an increase in the number of days with heavy precipitation over much of North America. Projected precipitation changes are more evident in the late 21st century than the mid 21st century, and they are more evident under RCP 8.5 than under RCP 4.5 in the late 21st century.

    This study performs high-spatial-resolution (12 km) Weather Research and Forecasting (WRF) simulations over a very large domain (7200 km × 6180 km, covering much of North America) to explore changes in mean and extreme precipitation in the mid and late 21st century under Representative Concentration Pathways 4.5 (RCP 4.5) and 8.5 (RCP 8.5). We evaluate WRF model performance for a historical simulation and future projections, applying the Community Climate System Model version 4 (CCSM4) as initial and boundary conditions with and without a bias correction. WRF simulations using boundary and initial conditions from both versions of CCSM4 show smaller biases versus evaluation data sets than does CCSM4 over western North America. WRF simulations also improve spatial details of precipitation over much of North America. However, driving the WRF with the bias-corrected CCSM4 does not always reduce the bias. WRF-projected changes in precipitation include decreasing intensity over the southwestern United States, increasing intensity over the eastern United Sates and most of Canada, and an increase in the number of days with heavy precipitation over much of North America. Projected precipitation changes are more evident in the late 21st century than the mid 21st century, and they are more evident under RCP 8.5 than under RCP 4.5 in the late 21st century. Uncertainties in the projected changes in precipitation due to different warming scenarios are non-negligible.

  12. Whooping Cough: A Brief History to the 19th Century.

    Weston, Robert

    2012-01-01

    This paper examines the history of whooping cough (pertussis) from its first recorded mention in 1190 to the time when its microbial cause was identified. The historical records of the disease are complicated by the variation in the nomenclature employed and through using the same name for disorders with different symptoms. During the early-modern period it was considered to be a disease new to Europe-contagious, dangerous, and potentially epidemic. Believed to be confined to children, its significance was limited until the 18th century when its incidence increased markedly. This essay argues pertussis may have occurred in the late medieval period in individual, though not epidemical, cases.

    We have presented the result of the analysis of the nighttime VLF signals transmitted from the Indian Navy station VTX (latitude 8.43°N, longitude 77.73°E) at 19.2 kHz and received at Kolkata (latitude 22.57°N, longitude 88.24°E). On 18th January, 2011 an earthquake of magnitude 7.4 occurred at Southwestern Pakistan (latitude 28.9°N, longitude 64°E). We have analyzed the nighttime VLF signals for 2 weeks around 18th of January, 2011 to see if there have been any precursory effects of this earthquake. We have found that the amplitude of the nighttime VLF signals anomalously fluctuated 4 days before the earthquake. This agrees well with our previous findings based on the analysis of 1 year of earthquake data.

    2014-04-01

    This study clarifies the causes of the repetitive occurrences of such phenomena as rinderpest, epidemic, famine, and tiger disasters recorded in the Joseon Dynasty Chronicle and the Seungjeongwon Journals in the period of great catastrophe, the late 17th century in which the great Gyeongsin famine (1670~1671) and the great Eulbyeong famine (1695~1696) occurred, from the perspective that they were biological exchanges caused by the new arrival of rinderpest in the early 17th century. It is an objection to the achievements by existing studies which suggest that the great catastrophes occurring in the late 17th century are evidence of phenomena in a little ice age. First of all, rinderpest has had influence on East Asia as it had been spread from certain areas in Machuria in May 1636 through Joseon, where it raged throughout the nation, and then to the west part of Japan. The new arrival of rinderpest was indigenized in Joseon, where it was localized and spread periodically while it was adjusted to changes in the population of cattle with immunity in accordance with their life spans and reproduction rates. As the new rinderpest, which showed high pathogenicity in the early 17th century, was indigenized with its high mortality and continued until the late 17th century, it broke out periodically in general. Contrastively, epidemics like smallpox and measles that were indigenized as routine ones had occurred constantly from far past times. As a result, the rinderpest, which tried a new indigenization, and the human epidemics, which had been already indigenized long ago, were unexpectedly overlapped in their breakout, and hence great changes were noticed in the aspects of the human casualty due to epidemics. The outbreak of rinderpest resulted in famine due to lack of farming cattle, and the famine caused epidemics among people. The casualty of the human population due to the epidemics in turn led to negligence of farming cattle, which constituted factors that triggered

  15. Late nineteenth to early twenty-first century behavior of Alaskan glaciers as indicators of changing regional climate

    Alaska's climate is changing and one of the most significant indications of this change has been the late 19th to early 21st century behavior of Alaskan glaciers. Weather station temperature data document that air temperatures throughout Alaska have been increasing for many decades. Since the mid-20th century, the average change is an increase of ?????2.0????C. In order to determine the magnitude and pattern of response of glaciers to this regional climate change, a comprehensive analysis was made of the recent behavior of hundreds of glaciers located in the eleven Alaskan mountain ranges and three island areas that currently support glaciers. Data analyzed included maps, historical observations, thousands of ground-and-aerial photographs and satellite images, and vegetation proxy data. Results were synthesized to determine changes in length and area of individual glaciers. Alaskan ground photography dates from 1883, aerial photography dates from 1926, and satellite photography and imagery dates from the early 1960s. Unfortunately, very few Alaskan glaciers have any mass balance observations. In most areas analyzed, every glacier that descends below an elevation of ?????1500??m is currently thinning and/or retreating. Many glaciers have an uninterrupted history of continuous post-Little-Ice-Age retreat that spans more than 250??years. Others are characterized by multiple late 19th to early 21st century fluctuations. Today, retreating and/or thinning glaciers represent more than 98% of the glaciers examined. However, in the Coast Mountains, St. Elias Mountains, Chugach Mountains, and the Aleutian Range more than a dozen glaciers are currently advancing and thickening. Many currently advancing glaciers are or were formerly tidewater glaciers. Some of these glaciers have been expanding for more than two centuries. This presentation documents the post-Little-Ice-Age behavior and variability of the response of many Alaskan glaciers to changing regional climate. ?? 2006.

    During the late eighteenth and early nineteenth centuries the Hudson's Bay Company served as a de facto public health agency across western Canada. Among its biggest challenges was combating the smallpox epidemics that periodically threatened the Aboriginal people of the region. Initially, the Company's employees turned to quarantine over variolation in order to prevent the spread of the disease to Hudson Bay in the summer of 1782. Although well thought-out, ultimately this policy proved unsuccessful. Within thirty years the HBC had turned to the newly discovered vaccination, a strategy that was to prove far more effective in fighting the disease. By the late 1830s the Company was able to mount an effective vaccination campaign that covered much of western Canada.

  5. Evolution of disability in late 19th century America: Civil War pensions for Union Army veterans with musculoskeletal conditions.

    Blanck, Peter; Linares, Claudia; Song, Chen

    2002-01-01

    This article examines the evolution of musculoskeletal (MSK) disability and its impact on mortality and work patterns in the late 19th century in America, in the context of the Civil War disability policy scheme. The study was conducted on 17,702 Union Army (UA) Civil War veterans. Of these, 10,789 were examined and diagnosed with major MSK conditions, rheumatism, sciatica, and spinal curvature, between 1862 and 1907. Analyses examine MSK (i) prevalence rates by birth cohort and age group; (ii) fatality rates as compared with other disabilities; (iii) risk rates by occupation type; and (iv) lifespan for MSK patients. MSK conditions are commonly claimed disabilities within the Civil War data set, with prevalence rates increasing with age. Regression studies show that working in clerical and professional (relative to manual labor) occupations decreases the likelihood of being examined for and diagnosed with MSK conditions. MSK patients examined at older ages tended to have longer lifespan than those examined at younger ages. The findings suggest that changes in age, environmental, and occupational conditions during the late 19th century affected MSK condition prevalence and the average lifespan of MSK patients. Implications for contemporary disability policy are discussed.

  6. Late Holocene megadroughts and temperature changes in the tropics: coherent century-scale climate variability across the tropics

    Shanahan, T. M.

    2011-12-01

    High latitude paleoclimate reconstructions for the late Holocene show large shifts in temperature and rainfall on century timescales, with the most notable of these events occurring during the Medieval Climate Anomaly and the Little Ice Age. The tropical manifestation of these events is less clear, though existing records seem to provide evidence for significant temperature and rainfall changes that are at least broadly synchronous with events at the high latitudes. Here we present new multiproxy geochemical and stable isotope (e.g., δ18O, δDleaf wax) records from sites in tropical South America, Africa and the West Pacific, which show strongly coherent and synchronous patterns of temperature and rainfall variability. These data provide a strong support for a dynamical linkage between the tropical monsoon systems, as well as between the tropics and the high latitudes on century timescales. Several sites also indicate that rainfall variations were accompanied by significant (e.g., 1-2 C) temperature changes, indicating that high latitude temperature depressions were propagated to the low latitudes during late Holocene cold intervals, though the mechanism driving these temperature changes is unclear.

  7. When realism made a difference: The constitution of matter and its conceptual enigmas in late 19th century physics

    NASA Astrophysics Data System (ADS)

    Wilholt, Torsten

    2008-01-01

    The late 19th century debate among German-speaking physicists about theoretical entities is often regarded as foreshadowing the scientific realism debate. This paper brings out differences between them by concentrating on the part of the earlier debate that was concerned with the conceptual consistency of the competing conceptions of matter-mainly, but not exclusively, of atomism. Philosophical antinomies of atomism were taken up by Emil Du Bois-Reymond in an influential lecture in 1872. Such challenges to the consistency of atomism had repercussions within the physics community, as can be shown for the examples of Heinrich Hertz and Ludwig Boltzmann. The latter developed a series of counter-arguments, culminating in an ingenious attempt to turn the tables on the critics of atomism and prove the inconsistency of non-atomistic conceptions of nature. Underlying this controversy is a disagreement over specific goals of physical research which was considered crucially relevant to the further course of physical inquiry. It thereby exemplifies an attitude towards the realism issue that can be contrasted with a different, more neutral attitude of construing the realism issue as merely philosophical and indifferent with respect to concrete research programs in physics, which one also occasionally finds expressed in the 19th century controversy and which may be seen as the prevailing attitude of the 20th century debate.

  12. Neurologic approaches to hysteria, psychogenic and functional disorders from the late 19th century onwards.

    PubMed

    Stone, J

    2017-01-01

    The history of functional neurologic disorders in the 20th century from the point of view of the neurologist is U-shaped. A flurry of interest between the 1880s and early 1920s gave way to lack of interest, skepticism, and concern about misdiagnosis. This was mirrored by increasing professional and geographic divisions between neurology and psychiatry after the First World War. In the 1990s the advent of imaging and other technology highlighted the positive nature of a functional diagnosis. Having been closer in the early 20th century but later more separate, these disorders are now once again the subject of academic and clinical interest, although arguably still very much on the fringes of neurology and neuropsychiatry. Revisiting older material provides a rich source of ideas and data for today's clinical researcher, but also offers cautionary tales of theories and treatments that led to stagnation rather than advancement of the field. Patterns of treatment do have a habit of repeating themselves, for example, the current enthusiasm for transcranial magnetic stimulation compared to the excitement about electrotherapy in the 19th century. For these reasons, an understanding of the history of functional disorders in neurology is arguably more important than it is for other areas of neurologic practice.

  13. Psychicones: Visual Traces of the Soul in Late Nineteenth-Century Fluidic Photography.

    PubMed

    Pethes, Nicolas

    2016-07-01

    The article discusses attempts to visualise the soul on photographic plates at the end of the nineteenth century, as conducted by the French physician Hippolyte Baraduc in Paris. Although Baraduc refers to earlier experiments on fluidic photography in his book on The Human Soul (1896) and is usually mentioned as a precursor to parapsychological thought photography of the twentieth century, his work is presented as a genuine attempt at photographic soul-catching. Rather than producing mimetic representations of thoughts and imaginations, Baraduc claims to present the vital radiation of the psyche itself and therefore calls the images he produces psychicones. The article first discusses the difference between this method of soul photography and other kinds of occult media technologies of the time, emphasising the significance of its non-mimetic, abstract character: since the soul itself was considered an abstract entity, abstract traces seemed all the more convincing to the contemporary audience. Secondly, the article shows how the technological agency of photography allowed Baraduc's psychicones to be tied into related discourses in medicine and psychology. Insofar as the photographic plates displayed actual visual traces, Baraduc and his followers no longer considered hallucinations illusionary and pathological but emphasised the physical reality and normality of imagination. Yet, the greatest influence of soul photography was not on science but on art. As the third part of the paper argues, the abstract shapes on Baraduc's plates provided inspiration for contemporary avant-garde aesthetics, for example, Kandinsky's abstract paintings and the random streams of consciousness in surrealistic literature.

    Health interventions against smallpox during the two epidemics in the second half of the 19th century are outlined. The 1871 hospital health report and the medical report on smallpox patients treated at the hospital and poorhouse of Ferrara between January 1891 and January 1892, drawn up by Alessandro Bennati, provide both interesting data and insights into the treatments and remedies of the time. The treatment of this illness was - and indeed could be - nothing other than symptomatic, there being no real means to halt the spread of the disease. Rather, other remedies were found by alleviating pain and regaining energy during the various stages of the disease. A close relationship between vaccination and the incidence and gravity of the illness is underlined. When the practice of vaccination started to be widely employed at the end of the century, there were almost no cases of death due to smallpox. The pharmacopoeias of the time, Antonio Campana's Farmacopea ferrarese in particular, proved an essential guide in the analysis of each document.

    2015-12-01

    Measles mortality fell prior to the introduction of vaccines or antibiotics. By examining historical mortality reports we sought to determine how much measles mortality was due to epidemiological factors such as isolation from major population centres or increased age at time of infection. Age-specific records were available from Aberdeen; Scotland; New Zealand and the states of Australia at the end of the 19th and beginning of the 20th centuries. Despite the relative isolation of Australia, measles mortality was concentrated in very young children similar to Aberdeen. In the more isolated states of Tasmania, Western Australia and Queensland adults made up 14-15% of measles deaths as opposed to 8-9% in Victoria, South Australia and New South Wales. Mortality in Iceland and Faroe Islands during the 1846 measles epidemic was used as an example of islands isolated from respiratory pathogens. The transition from crisis mortality across all ages to deaths concentrated in young children occurred prior to the earliest age-specific mortality data collected. Factors in addition to adult age of infection and epidemiological isolation such as nutritional status and viral virulence may have contributed to measles mortality outcomes a century ago.

  16. PSYCHOLOGY IN FRENCH ACADEMIC PUBLISHING IN THE LATE NINETEENTH CENTURY: ALFRED BINET, EDITORIAL DIRECTOR AT THE SCHLEICHER PUBLISHING HOUSE.

    PubMed

    Nicolas, Serge

    2015-01-01

    To date, historians of psychology have largely ignored the role of academic publishing and the editorial policies of the late nineteenth century. This paper analyzes the role played by academic publishing in the history of psychology in the specific case of France, a country that provides a very interesting and unique model. Up until the middle of the 1890s, there was no collection specifically dedicated to psychology. Alfred Binet was the first to found, in 1897, a collection of works specifically dedicated to scientific psychology. He chose to work with Reinwald-Schleicher. However, Binet was soon confronted with (1) competition from other French publishing houses, and (2) Schleicher's management and editorial problems that were to sound the death knell for Binet's emerging editorial ambitions. The intention of this paper is to encourage the efforts of the pioneers of modern psychology to have their work published and disseminated.

    Parasitological examination of samples from tombs of the Korean Joseon Dynasty (1392-1910) could be helpful to researchers in understanding parasitic infection prevalence in pre-industrial Korean society. Whereas most of our previous parasitological studies revealed the presence of ancient parasite eggs in coprolites of Korean mummies, a sample from a man living in late 17th century Korea proved to be relatively unique in possessing what appeared to be several species of parasite larvae. The larvae identified included Strongyloides stercoralis and Trichostrongylus spp., along with eggs of Ascaris lumbricoides, Trichuris trichiura, and Paragonimus westermani. Since ancient parasite larvae retain enough morphology to make proper species identification possible, even after long burial times, the examination of parasite larvae within ancient samples will be conducted more carefully in our future work.

  18. Late Holocene history of Chaitén Volcano: new evidence for a 17th century eruption

    Lara, Luis E.; Moreno, Rodrigo; Amigo, Álvaro; Hoblitt, Richard P.; Pierson, Thomas C.

    2013-01-01

    Prior to May 2008, it was thought that the last eruption of Chaitén Volcano occurred more than 5,000 years ago, a rather long quiescent period for a volcano in such an active arc segment. However, increasingly more Holocene eruptions are being identified. This article presents both geological and historical evidence for late Holocene eruptive activity in the 17th century (AD 1625-1658), which included an explosive rhyolitic eruption that produced pumice ash fallout east of the volcano and caused channel aggradation in the Chaitén River. The extents of tephra fall and channel aggradation were similar to those of May 2008. Fine ash, pumice and obsidian fragments in the pre-2008 deposits are unequivocally derived from Chaitén Volcano. This finding has important implications for hazards assessment in the area and suggests the eruptive frequency and magnitude should be more thoroughly studied.

  19. Science, suffrage, and experimentation: Mary Putnam Jacobi and the controversy over vivisection in late nineteenth-century America.

    PubMed

    Bittel, Carla Jean

    2005-01-01

    This article examines the medical activism of the New York physician Mary Putnam Jacobi (1842-1906), to illustrate the problems of gender and science at the center of the vivisection debate in late nineteenth-century America. In the post-Civil War era, individuals both inside and outside the medical community considered vivisection to be a controversial practice. Physicians divided over the value of live animal experimentation, while reformers and activists campaigned against it. Jacobi stepped into the center of the controversy and tried to use her public defense of experimentation to the advantage of women in the medical profession. Her advocacy of vivisection was part of her broader effort to reform medical education, especially at women's institutions. It was also a political strategy aimed at associating women with scientific practices to advance a women's rights agenda. Her work demonstrates how debates over women in medicine and science in medicine, suffrage, and experimentation overlapped at a critical moment of historical transition.

    Reconstructions of past climate and ocean variability and of the response of the marine ecosystems from high-resolution marine archives are critical to our understanding of climate/ocean dynamics and its links with ecosystem change. Laminated sediments preserved in the Peruvian margin within the oxygen minimum zone allow reconstructing past climate/ocean variability and environmental changes from interannual to centennial or longer time-scales (Gutierrez et al., 2009). We investigated proxy records in laminated sediments downstream the main upwelling area of the Peruvian coast (off Pisco, 14° S, 300m water depth) aiming at reconstructing variations of sea-surface temperature and biological productivity during the past century in order to explore potential (global warming related) changes in the intensity of coastal upwelling and ecosystem response. Dating of the sediment core revealed extremely high sedimentation rates of 1.9-2.3 mm/year for the period since the late nineteenth century to the present (Gutierrez et al., 2009). SST values, reconstructed from the alkenone unsaturation index (Uk'37), are within the range observed in the Pisco coastal area during spring/summer, when productivity (inferred from Chl-a) is highest. They show conspicuous positive/negative excursions which are generally in-line with known past El Nino/El Nina events. The record reveals significant multidecadal variability: SSTs smoothly decrease from 1880 to ca.1920, show little variation between 1920 and 1945 followed by a steady rapid cooling of ca. 1.5° C in the latter part of the 20th century (after 1950). This trend is consistent with instrumental inshore SST time-series from central and southern Peru which also exhibit significant cooling since 1950 and with satellite SST data. Yet, for the same period, these data are not in line with ICOADS-SSTs, most likely depicting a strong onshore-offshore gradient. The negative SST changes coincide with increased, upwelling favorable alongshore

    The observed intensity, frequency, and duration (IFD) of summer wet spells, defined here as extreme events with one or more consecutive days in which daily precipitation exceeds a given threshold (the 95th percentile), and their future changes in RCP4.5 and RCP8.5 in the late 21st century over China, are investigated by using the wet spell model (WSM) and by extending the point process approach to extreme value analysis. Wet spell intensity is modeled by a conditional generalized Pareto distribution, frequency by a Poisson distribution, and duration by a geometric distribution, respectively. The WSM is able to realistically model summer extreme rainfall spells during 1961-2005, as verified with observations at 553 stations throughout China. To minimize the impact of systematic biases over China in the global climate models (GCMs) of the Coupled Model Intercomparison Project Phase 5 (CMIP5), five best GCMs are selected based on their performance to reproduce observed wet spell IFD and average precipitation during the historical period. Furthermore, a quantile-quantile scaling correction procedure is proposed and applied to produce ensemble projections of wet spell IFD and corresponding probability distributions. The results show that in the late 21st century, most of China will experience more extreme rainfall and less low-intensity rainfall. The intensity and frequency of wet spells are projected to increase considerably, while the duration of wet spells will increase but to a much less extent. The IFD changes in RCP8.5 are in general much larger than those in RCP4.5.

    Hemostatic options available to the surgeon in the late 19th and early 20th centuries were limited. The surgical ligature was limited in value to the neurological surgeon because of the unique structural composition of brain tissue as well as the approaches and operating angles used in this type of surgery. In this manuscript the authors review the options available and the evolution of surgical hemostatic techniques and electrosurgery in the late 19th and early 20th centuries and the impact of these methods on the surgical management of tumors of the brain and its coverings.

  3. On the Cause of the Great North Atlantic Hurricane Drought of the Late 20th Century

    2015-12-01

    By all sensible metrics, North Atlantic tropical cyclone activity underwent a pronounced decline from the middle of the 20th Century through the 1980s, and then recovered. A rich literature is devoted to the causes is this hurricane drought, with some arguing that it is part of a natural, multi-decadal oscillation of North Atlantic climate, and others pointing to time-varying radiative forcing as the main cause of the drought. In this work I show that the net variability of Atlantic tropical cyclone activity in the second half of the 20th Century has two spectral peaks: One around a single decade and another at a period close to 70 years. I hypothesize that the longer period variability, of which the drought was a part, was principally owing to time-varying radiative forcing, while the quasi-decadal signal is part of a natural oscillation of North Atlantic climate. To test this hypothesis, I present evidence that the two main contributors to time-varying radiative forcing over the period were CO2 variations and aerosol forcing brought about by a combination of sulfate originating in European sulfur emissions and natural mineral dust from the Sahara, and then show that most of the longer-period variations can be statistically explained by a combination of these two forcing agents, at the same time demonstrating that the spatial pattern on this variability is consistent with the radiative forcing hypothesis. On the other hand, the spatial pattern of the quasi-decadal variations is closely aligned with that of the EOFs of natural variability in a large suite of unforced, coupled climate models, suggesting that this quasi-decadal signal is part of a natural oscillation of the North Atlantic climate.

  4. Psychicones: Visual Traces of the Soul in Late Nineteenth-Century Fluidic Photography

    2016-01-01

    The article discusses attempts to visualise the soul on photographic plates at the end of the nineteenth century, as conducted by the French physician Hippolyte Baraduc in Paris. Although Baraduc refers to earlier experiments on fluidic photography in his book on The Human Soul (1896) and is usually mentioned as a precursor to parapsychological thought photography of the twentieth century, his work is presented as a genuine attempt at photographic soul-catching. Rather than producing mimetic representations of thoughts and imaginations, Baraduc claims to present the vital radiation of the psyche itself and therefore calls the images he produces psychicones. The article first discusses the difference between this method of soul photography and other kinds of occult media technologies of the time, emphasising the significance of its non-mimetic, abstract character: since the soul itself was considered an abstract entity, abstract traces seemed all the more convincing to the contemporary audience. Secondly, the article shows how the technological agency of photography allowed Baraduc’s psychicones to be tied into related discourses in medicine and psychology. Insofar as the photographic plates displayed actual visual traces, Baraduc and his followers no longer considered hallucinations illusionary and pathological but emphasised the physical reality and normality of imagination. Yet, the greatest influence of soul photography was not on science but on art. As the third part of the paper argues, the abstract shapes on Baraduc’s plates provided inspiration for contemporary avant-garde aesthetics, for example, Kandinsky’s abstract paintings and the random streams of consciousness in surrealistic literature.

    Pflüger's hypothesis of a nerve reflex as the cause of menstruation published in 1865 and accepted by many, nonetheless did not lead to experimental investigations for 25 years. According to this hypothesis the nerve reflex starts in the ovary by an increase of the intraovarian pressure by the growing follicles. In 1884 Adolph Kehrer proposed a program to test the nerve reflex, but only in 1890, Cohnstein artificially increased the intraovarian pressure in women by bimanual compression from the outside and the vagina. His results were not convincing. Six years later, Strassmann injected fluids into ovaries of animals and obtained changes in the uterus resembling those of oestrus. His results seemed to verify a prognosis derived from Pflüger's hypothesis. Thus, after a long interval, that hypothesis had become a paradigma. Though reasons can be given for the delay, it is little understood, why experimental testing started so late.

    The EW-trending Kunlun Fault System (KFS) is one of the major left-lateral strike-slip faults on the Tibetan Plateau. It forms the northern boundary of the Bayan Har block. Heretofore, no evidence has been provided for the most recent event (MRE) of the 70-km-long eastern section of the KFS. The studied area is located in the north of the Zoige Basin (northwest Sichuan province) and was recognized by field mapping. Several trenches were excavated and revealed evidence of repeated events in late Holocene. The fault zone is characterized by a distinct 30-60-cm-thick clay fault gouge layer juxtaposing the hanging wall bedrock over unconsolidated late Holocene footwall colluvium and alluvium. The fault zone, hanging wall, and footwall were conformably overlain by undeformed post-MRE deposits. Samples of charred organic material were obtained from the top of the faulted sediments and the base of the unfaulted sediments. Modeling of the age of samples, earthquake yielded a calibrated 2σ radiocarbon age of A.D. 1489 ± 82. Combined with the historical earthquake record, the MRE is dated at A.D. 1488. Based on the over 50 km-long surface rupture, the magnitude of this event is nearly M w 7.0. Our data suggests that a 200-km-long seismic gap could be further divided into the Luocha and Maqu sections. For the last 1000 years, the Maqu section has been inactive, and hence, it is likely that the end of its seismic cycle is approaching, and that there is a potentially significant seismic hazard in eastern Tibet.

The management of the program has been decentralized to the DOE Oak Ridge Operations Office and Oak Ridge National Laboratory (ORNL). The research is performed by staff members at ORNL and by researchers at other national laboratories, universities, and in private industry. The work is divided into the following categories: (1) structural, ceramics, (2) new alloys and coatings, (3) functional materials, and (4) technology development and transfer.

  8. The effect of aerosols and sea surface temperature on China's climate over the late twentieth century

    2015-04-01

    Focusing on China in the second half of the twentieth century, we examine the relative role of aerosols and prescribed, observation based sea surface temperatures (SSTs) for the evolution of surface solar radiation (SSR), surface air temperature (SAT), and precipitation in ensembles of transient (1870 - 2005) sensitivity experiments with the global climate model ECHAM5-HAM. Observations and simulations with transient SSTs and aerosol emissions agree reasonably well in eastern China in terms of SSR dimming (-6 +/- 2 W/m2/decade, 1960 - 2000), statistically non-significant JJA SAT trend (1950 - 2000), and drying in JJA from 1950 to 1990 (-2.5% to -3.5% per decade, essentially via reduction of convective precipitation). Other major observed features are not reproduce by the model, e.g. precipitation increase in the 1990s in the Yangtze valley, the strong warming in winter in northern parts of China and Mongolia, or SSR dimming in western China. For the model results, SO2 emissions are more relevant than emissions of black and organic carbon. Aerosol effects are less pronounced at higher model resolution. Transient SSTs are found to be crucial for decadal scale SAT variability over land, especially the strong warming in the 1990s, and, via SST forced reduction of cloud cover, for the ceasing of SSR dimming around the year 2000. Unforced cloud variability leads to relevant scatter (up to +/- 2 W/m2/decade) of modeled SSR trends at individual observation sites.

    Instrumental observations suggest that Lake Tanganyika, the largest rift lake in East Africa, has become warmer, increasingly stratified and less productive over the past 90years (refs 1,2). These trends have been attributed to anthropogenic climate change. However, it remains unclear whether the decrease in productivity is linked to the temperature rise, and whether the twentieth-century trends are anomalous within the context of longer-term variability. Here, we use the TEX86 temperature proxy, the weight per cent of biogenic silica and charcoal abundance from Lake Tanganyika sediment cores to reconstruct lake-surface temperature, productivity and regional wildfire frequency, respectively, for the past 1,500years. We detect a negative correlation between lake-surface temperature and primary productivity, and our estimates of fire frequency, and hence humidity, preclude decreased nutrient input through runoff as a cause for observed periods of low productivity. We suggest that, throughout the past 1,500years, rising lake-surface temperatures increased the stratification of the lake water column, preventing nutrient recharge from below and limiting primary productivity. Our records indicate that changes in the temperature of Lake Tanganyika in the past few decades exceed previous natural variability. We conclude that these unprecedented temperatures and a corresponding decrease in productivity can be attributed to anthropogenic global warming, with potentially important implications for the Lake Tanganyika fishery.

  10. Suitable and remunerative employment: the feminization of hospital dispensing in late nineteenth-century England.

    PubMed

    Jordan, Ellen

    2002-12-01

    This article looks at the contingent developments that led to the feminization of hospital dispensing at the end of the nineteenth century in England. In the 1870s, as a result of the campaign of the Women's Movement to open medicine to women, the Society for Promoting the Employment of Women found it possible to place some of its protégées in the dispensaries of hospitals founded by members of the Movement. Coincidentally, a radical member of the Council of the Pharmaceutical Society smoothed the way for them to take the Society's examinations, thus setting up an expectation that these women should be qualified. By the 1880s, the practice of employing female dispensers had spread to Birmingham, and the women here adopted a less difficult and expensive qualification, the Apothcaries' Assistant's Certificate, as the qualification of choice. The 1890s also saw increasing pressure on mainstream hospital dispensaries to replace the untrained assistants in their dispensaries, customarily employed on the Babbage Principle to save money, with qualified ones. In consequence, hospital managements sought a new means of containing costs and, turning to the kind of women already shown to be competent in Women's Movement hospitals, found the solution in a vertical gender-segregation, where the lesser qualification of women dispensers made them 'unpromotable' to head dispenser, thus preserving the career ladder for more highly-qualified male dispensers.

    We use family fixed-effects models to estimate the impact of childhood health on adult literacy, labor force outcomes, and marital status among pairs of white brothers observed as children in the 1880 U.S. Census and then as adults in the 1900–1930 Censuses. Given our focus on the 19th century, we observed a wider array of infectious, chronic, and traumatic health problems than is observed using data that are more recent; our results thus provide some insights into circumstances in modern developing countries where similar health problems are more frequently observed. Compared to their healthy siblings, sick brothers were less likely to be located (and thus more likely to be dead) 20–50 years after their 1880 enumeration. Sick brothers were also less likely to be literate, to have ever been married, and to have reported an occupation. However, among those with occupations, sick and healthy brothers tended to do similar kinds of work. We discuss the implications of our results for research on the impact of childhood health on socioeconomic outcomes in developed and developing countries. PMID:22809795

    It has been widely disseminated in the literature that subcutaneous packing, as part of mummification, was not usually done until the 21st dynasty. We aimed to study by computed tomography (CT) if subcutaneous packing was part of mummification of royal Egyptians dated to 18th to 20th dynasties. We analyzed the 2- and 3-dimensional CT images of 13 royal mummies dated to circa 1550 to 1153 BC for presence of subcutaneous embalming materials. Among the studied mummies were Amenhotep III, Tutankhamun, Seti I, and Ramesses II. We reported the CT characters of any detected subcutaneous embalming materials and noted their impact on the morphology of the involved body part. We correlated the CT findings with the archeological literature. Computed tomographic images showed subcutaneous packing in 12 (92.3%) mummies; whereas the mummy that was previously known as "Thutmose I" showed no such evidence. Subcutaneous packing involved the faces (n = 11), necks (n = 4), torsos (n = 5), and/or extremities (n = 4) of the mummies. Subcutaneous filling materials showed variation in homogeneity and CT densities and they were likely composed of resin, bits of linen with resin, or other substances. Subcutaneous packing procedure succeeded in providing uniform full contour of the involved body regions without causing significant tissue damages. Subcutaneous packing procedure was used as part of mummification of royal Ancient Egyptians dated to 18th to 20th dynasties earlier than what was believed in archaeology. The Ancient Egyptian embalmers must have been skilled in dissection and possessed surgical tools that enabled them to perform this fine procedure.

    One of the two most extensive instrument collections in the Netherlands during the second half of the eighteenth century—rivaling the much better known collection at the University of Leiden—belonged to an orphanage in The Hague that was specially established to mold hand-picked orphans into productive citizens. (The other was housed at the Mennonite Seminary in Amsterdam, for use in the education of its students.) The educational program at this orphanage, one of three established by the Fundatie van Renswoude, grew out of a marriage between the socially-oriented generosity of the wealthy Baroness van Renswoude and the pedagogical vision of the institute's director and head teacher—a vision that fit with the larger movement of oeconomic patriotism. Oeconomic patriotism, similar to `improvement' and oeconomic movements in other European countries and their colonies, sought to tie the investigation of nature to an improvement of society's material and moral well-being. Indeed, it was argued that these two facets of society should be viewed as inseparable from each other, distinguishing the movement from more modern conceptions of economics. While a number of the key figures in this Dutch movement also became prominent Patriots during the revolutionary period at the end of the century, fighting against the House of Orange, they did not have a monopoly on oeconomic ideas of societal improvement. This is demonstrated by the fact that an explicitly pro-Orangist society, Mathesis Scientiarum Genitrix, was organized in 1785 to teach science and mathematics to poor boys and orphans for very similar reasons: to turn them into productive and useful citizens. As was the case with the Fundatie van Renswoude, a collection of instruments was assembled to help make this possible. This story is of interest because it discusses a hitherto under-examined use to which science education was put during this period, by revealing the link between such programs and the highly

    The hydroxyl radical, OH, is the dominant sink for the majority of trace gases in the troposphere. Thus, it plays a major role in controlling atmospheric chemical composition. However despite this importance there remains much uncertainty as to whether concentrations of OH have changed in the background atmosphere in recent decades. It has previously been reported that recent levels of OH in the troposphere (1997-2008) are well buffered against changes in atmospheric composition (Montzka et al., 2011). We present two independent records that suggest that there was a significant increase in concentrations of the OH radical in the northern hemisphere during the last two decades of the twentieth century. Measurements from Greenland firn air of the changing ratios of n-butane, iso-butane, n-pentane and iso-pentane were compared using a photochemical clock method. Using these changing ratios we calculate an increase in the chemical processing of the air (i.e. [OH].t) between 1980 and 2000. Assuming t to be constant this provides a semi-quantitative historic record of OH concentrations. Furthermore, measurements of three alkyl nitrates (also from Greenland firn air), secondary oxidation products of the alkanes, suggest an increase in the [NO]/[HO2] ratio in the background atmosphere. This could be indicative of increasing NOx concentrations during this period, which would be consistent with increasing [OH]. These two records are further corroborated by comparison with the long term trend in increasing ozone mixing ratios from background European sites. Knowledge of historic changes to the oxidative capacity of the atmosphere is fundamental to understanding the atmospheric records of trace gases and to determining historic trace gas emissions using top-down approaches. The results presented here have profound implications for our understanding of atmospheric composition in the past, the present and for predicting the future evolution of the atmosphere.

    Accelerated losses of biodiversity are a hallmark of the current era. Large declines of population size have been widely observed and currently 22,176 species are threatened by extinction. The time at which a threatened species began rapid population decline (RPD) and the rate of RPD provide important clues about the driving forces of population decline and anticipated extinction time. However, these parameters remain unknown for the vast majority of threatened species. Here we analyzed the genetic diversity data of nuclear and mitochondrial loci of 2,764 vertebrate species and found that the mean genetic diversity is lower in threatened species than in related nonthreatened species. Our coalescence-based modeling suggests that in many threatened species the RPD began ∼123 y ago (a 95% confidence interval of 20–260 y). This estimated date coincides with widespread industrialization and a profound change in global living ecosystems over the past two centuries. On average the population size declined by ∼25% every 10 y in a threatened species, and the population size was reduced to ∼5% of its ancestral size. Moreover, the ancestral size of threatened species was, on average, ∼22% smaller than that of nonthreatened species. Because the time period of RPD is short, the cumulative effect of RPD on genetic diversity is still not strong, so that the smaller ancestral size of threatened species may be the major cause of their reduced genetic diversity; RPD explains 24.1–37.5% of the difference in genetic diversity between threatened and nonthreatened species.

    The Late Medieval Period was a decisive period in the history of medicine. It was then that medical education was integrated into the universities that were coming into existence and when medicine made its transition from a menial trade to a regulated profession with a statutory basis of learning and graduation. It was also then that the necessities of understanding the fabric of the body was realized; for the first time in history, the study of anatomy and of human dissection were incorporated into the medical curriculum. This was a defining change whose subsequent expansion and evolution would bring about the study of function (physiology) and changes in disease (pathology). Few advances were made in the study of the kidney, which was considered part of the venous circulation, whose function was subservient to that of nutrition in eliminating excess fluid. Uroscopy flourished and reached unrealistic levels of dominance in the diagnosis, treatment, and prognostication of any and all diseases, especially in the hands of quacks and charlatans. Alchemy, a mysterious pseudo-science, blossomed into a discipline that nurtured experimentation and laid the rudimentary foundations of scientific study, chemistry, and pharmacology. It was also then that surgery took form as a specialty that actually provided much of the medical care of the period including that of the principal diseases of the kidney, obstruction and calculi, and thereby laid the foundations of what in time would become urology.

    In the second half of the 1890s a drought-driven ecological crisis took hold in the region of modern-day Botswana, Zimbabwe and northern, central and eastern South Africa. A number of years of very late rainy seasons had severe repercussions for the rain-fed agriculture. Sowing was delayed and the young crops suffered from below average summer rainfall levels. Drawing on a wide variety of documentary sources - administrative records, writings by members of missionary societies and local newspapers - this paper outlines how the drought drove the ecological crisis and aggravated a locust infestation and the cattle plague (rinderpest). Whereas the locusts found better breeding conditions in areas that were normally too humid for them, the drought also facilitated the spread of rinderpest by reducing the number of watering holes and by forcing the cattle into an immunodepressed state due to malnutrition. The locusts contributed to the loss of grain crops, and the rinderpest decimated cattle herds by more than 90 per cent in areas where the disease coincided with the drought. As agriculture as well as the pastoral sector were hit hard, famine conditions developed in the interior of the region.

    From the 17th to the 18th centuries, missionaries in Southeast Asia dedicated themselves to providing and establishing a professional medical-pharmaceutical supply for the local population and therefore explored the genuine Materia medica for easily available and affordable remedies, especially medicinal plants. In characteristic medical-pharmaceutical compendia, which can be classified as missionary pharmacopoeias, they laid down their knowledge to advise others and to guarantee a professional health care. As their knowledge often resulted from an exchange with indigenous communities, these compendia provide essential information about traditional plant uses of Southeast Asian people. Individual missionaries such as the Jesuit Georg Joseph Kamel (1661-1706) not only strove to explore medicinal plants but performed botanical studies and even composed comprehensive herbals. The Jesuit missionaries in particular played roles in both the order's own global network of transfer of medicinal drugs and knowledge about the application, and within the contemporary local and European scientific networks which included, for example, the famous Royal Society of London. The results of their studies were distributed all over the world, were introduced into the practical Materia medica of other regions, and contributed significantly to the academization of knowledge. In our article we will explain the different intentions and methods of exploring, the resulting works and the consequences for the forming of the pharmaceutical and scientific knowledge. Finally, we will show the options which the works of the missionaries can offer for the saving of traditional ethnopharmacological knowledge and for the development of modern phytotherapeutics and pharmaceutical supply. The publication is based on a comprehensive study on the phenomenon of missionary pharmacy which has been published as a book in 2011 (Anagnostou, 2011a) and shows now the potential of historical medical

  2. Astrometry and early astrophysics at Kuffner Observatory in the late 19th century

    NASA Astrophysics Data System (ADS)

    Habison, Peter

    The astronomer and mathematician Norbert Herz encouraged Moriz von Kuffner, owner of the beer brewery in Ottakring, to finance a private scientific observatory in the western parts of Vienna. In the years 1884-87 the Kuffner Observatory was built at the Gallitzinberg in Wien-Ottakring. It was an example of enlighted patronage and noted at the time for its rapid acquisition of new instruments and by increasing international recognition. It contained the largest heliometer in the world and the largest meridian circle in the Austrian-Hungarian Empire. Of the many scientists who worked here we mention Leo de Ball, Gustav Eberhard, Johannes Hartmann and we should not forget Karl Schwarzschild. Here in Vienna he published papers on celestial mechanics, measuring techniques, optics and his fundamental papers concerning photographic photometry, in particular the quantitative determination of the departure of the reciprocity law. The telescope and the associated camera with which he carried out his measurements are still in existence at the observatory. The observatory houses important astronomical instruments from the 19th century. All telescopes were made by Repsold und Söhne in Hamburg, and Steinheil in Munich. These two German companies were best renowned for quality and precision in high standard astronomical instruments. The Great Refractor (270/3500 mm) is still the third largest refractor in Austria. It was installed at the observatory in 1886 and was used together with the Schwarzschild Refractor for early astrophysical work including photography. It is this double refractor, where Schwarzschild carried out his measurements on photographic photometry. The Meridian Circle (132/1500 mm) was the largest meridian passage instrument of the Austro-Hungarian Empire. Today it is the largest meridian circle in Austria and still one of the largest in Europe. The telescope is equipped with one of the first impersonal micrometers of that time.

    Consecutive volcanic eruptions during the second half of 13th century were hypothesized to have initiated the transition from the Medieval Warm Period to the Little Ice Age. To test this hypothesis, we study the climatic impact on the Northern Hemisphere high-latitudes by the historical volcanism with a focus on its potential dependency on the state of Arctic sea ice cover, using the Community Climate System Model Version 3 (CCSM3). Our results suggest the instantaneous volcanic climatic impact is a fairly robust phenomenon with a spatial pattern that is insensitive to the Arctic sea ice state; whereas the long-term integrated impact is susceptible to the Arctic state and contingent on a responsive overturning circulation in the Northern North Atlantic and the Arctic Ocean, which could get weaker transporting less heat poleward and thus help sustain the Arctic surface cooling. Further experiments employing the Community Atmosphere Model (CAM) stand-alone version show the volcanic impact via atmospheric physical and dynamic processes is short-lived up to a couple of years, in consistent with previous studies, while the longer-term persistence can be achieved through coupling with the underlying Ocean and Cryosphere. When the Atmosphere-Ocean-Cryosphere is interactive, nonlinearity occurs with the short-term climate response to volcanism in the sense that a winter warming pattern across northern Eurasia is found in the case of weaker volcanism, but a general cooling pattern as the volcanic forcing gets stronger. Previous studies argued for dominancy by atmosphere dynamic warming effect in the former case and direct radiative cooling effect in the latter. However, our CAM stand-alone experiments with fixed sea surface temperature and sea ice cover yield warming across northern Eurasia regardless of the strength of volcanism, hinting at an ocean/sea ice control of continental climate. Further attribution efforts suggest the expanding Arctic sea ice resultant from

    The study is focused on future changes in climate extremes over the northern Eurasia. The changes in the extreme indices for the mid 21st century relative to the late 20th century have been inferred from CMIP3 daily temperature and precipitation output. It has been found that modeling temperature extremes are in reasonable agreement with reanalysis. Future projections for the extremes in Northern Eurasia are prone to large uncertainties arising primarily from intermodel differences. The uncertainties for «warm» extremes are larger than for «cold» extremes not only due to greater model-to-model differences but also due to slower warming of the former. In the warm season the models project drier climate conditions over some regions of the northern Eurasia, longer droughts, fewer number of wet days and increased heavy precipitation intensity. The AOGCM simulated changes in the extremes lack credibility due to low spatio-temporal resolution of current global models. There is a pressing need to further investigate the impact related aspects of regional climate changes over the northern Eurasia using sufficiently large ensembles of RCM simulations at 10-50 km resolution. Currently, the most dramatic warming in Eurasia is expected to occur in the regions for which a very limited number of single RCM simulations exists (e.g., central and eastern Russia). The MGO RCM has been developed at 50 and 25 km resolutions for three domains: Western Russia, Siberia, and Europe. The regional climate change simulation has been performed and analysis of daily temperature variability and fire danger conditions has been carried out.

    Due to the scarcity of surface solar radiation measurements and the lack of long term time series of this variable, sunshine duration (SDu) has been widely considered as a useful proxy for surface total solar radiation (TSR) reaching the earth. Numerous relationships between SDu and TSR have been proposed which vary between sites, as a result of the dependence of the two variables from climatic and astronomical components. At the National Observatory of Athens (NOA), measurements of sunshine duration and surface total solar radiation have been conducted continuously since 1897 and 1953 respectively. These are the longest uninterrupted time series of SDu and TSR in the country. The ability of SDu observations at NOA to serve as a proxy for the estimation of TSR and the detection of its interannual and multi decadal variability is examined in the study. Using the respective time series we have retrieved the relationship between SDu and TSR on a monthly, seasonal and annual basis. To test the retrieved functions we have derived them for the period 1985-2013 and tested them for the period 1953-1984, where synchronous SDu and TSR measurements are available. A strong linear relationship between the time series of monthly SDU and TSR was found. The two series were highly correlated (correlation coefficient > 0.95, p<0.001). On a seasonal basis, stronger correlation between SDu and TSR was detected in winter, autumn and spring, when SDu and TSR exhibit larger variability due to cloudiness. The correlation coefficient was lower in summer, when almost clear sky conditions prevail in Athens. The results showed that SDu observations in Athens can successfully provide quantitative information on shortwave solar radiation, particularly under all-sky conditions. The calculated functions can be used for the reconstruction of TSR back to the late 19th century. This unique 115-yrs SDu and TSR retrieved datasets can provide valuable and unknown information of TSR variability over the

    In 2005, an adult male was excavated in the cloister of the former Convent of the Holy Spirit, in the Franciscan Province of Holy Mary of Arrábida, Lisbon district. From the anterior part of the sacrum, a darker organic agglomeration was collected and studied for intestinal parasites. Samples were rehydrated with Lycopodium tablets in a Na3PO4 5% solution for 72h, followed by the swirl technique. Organic material was concentrated at 2500rpm. At least 20 slides of each sample were examined using a light/polarized microscope. A control sample from outside the pelvis revealed no biological remains. A sample collected inside the pelvic girdle was positive for pollen grains, other plant remains and Toxocara eggs, perhaps T. cati (2766 eggs/gram sediment). This finding, although exciting, cannot be explained in a simple way because humans are not definitive hosts for Toxocara species. Ingestion of feces-contaminated food or water, geophagy, or true infection are hypotheses considered in this study, which demonstrates the difficulty of interpreting the presence of animal parasites in human remains. This is the first time Toxocara eggs are found associated with human remains. Copyright © 2017 Elsevier Inc. All rights reserved.

    Benjamin Franklin had at least two accidents that resulted in electricity passing through his brain. In addition, he witnessed a patient's similar accident and performed an experiment that showed how humans could endure shocks to the head without serious ill effects, other than amnesia. Jan Ingenhousz, Franklin's Dutch-born medical correspondent better known for his discovery of photosynthesis, also had a serious accident that sent electricity though his head and, in a letter to Franklin, he described how he felt unusually elated the next day. During the 1780s, Franklin and Ingenhousz encouraged leading French and English electrical "operators" to try shocking the heads of melancholic and other deranged patients in their wards. Although they did not state that they were responding to Ingenhousz's and Franklin's suggestions, Birch, Aldini, and Gale soon did precisely what Ingenhousz and Franklin had suggested. These practitioners did not appear to induce convulsions in their mentally ill patients, but they still reported notable successes.

    Global climate change in the form of extreme, variation, and short- or mid-term fluctuation is now widely conceived to challenge the survival of the human beings and the societies. Meanwhile, improving present and future climate modeling needs a comprehensive understanding of the past climate patterns. Although historical climate modeling has gained substantive progress in recent years based on the new findings from dynamical meteorology, phenology, or paleobiology, less known are the mid- to short-term variations or lower-frequency variabilities at different temporal scale and their regional expressions. Enabling accurate historical climate modeling would heavily rely on the robustness of the dataset that could carry specific time, location, and meteorological information in the continuous temporal and spatial chains. This study thus presents an important methodological innovation to reconstruct historical climate modeling at multiple temporal and spatial scales through building a historical climate dataset, based on the Chinese chronicles compiled in a Zhang (2004) edited Compendium of Chinese Meteorological Records of the Last 3,000 Years since Zhou Dynasty (1100BC). The dataset reserves the most delicate meteorological data with accurate time, location, meteorological event, duration, and other phonological, social and economic impact information, and is carefully digitalized, coded, and geo-referenced on the Geographical Information System based maps according to Tan's (1982) historical atlas in China. The research project, beginning in January 2015, is a collaborative work among scholars across meteorology, geography, and historical linguistics disciplines. The present research findings derived from the early 100+ years of the Qing dynasty include the following. First, the analysis is based on the sampling size, denoted as cities/counties, n=1398 across the Mainland China in the observation period. Second, the frequencies of precipitation, cold-warm temperature, flood and drought with an index of social unrest are counted in an interval of a year, five years, ten years, and twenty years to gain their running mean(s) for every cites/counties to depict their temporal variations. Third, the cities and counties are divided into seven zones based on their meteorological and geographical characteristics, in order to interpret the regional expressions of the climate variations. Finally, the Ordinary Least Square regression model is used to estimate the coefficients among precipitation, temperature, flood and drought. Significantly, it is found that in general all these indices fluctuated in past 100+ years. However, the occurrence of drought and flood all have significant correlation with lower (colder) temperature (P=0.00) and also with precipitation (P<0.05). This implies that cold temperature tends to have higher meteorological extremes, and both flood and drought can occur approximately in the same year with abundant precipitation at different time. Among seven geographical zones, North China is found more vulnerable to the temperature changes considering these extreme weathers. Temperature change in Central and South China however are less significant. Central China on the other hand is more sensitive to the precipitation that are both correlated with drought and flood.

    In 1790, Marie Rozette, a freedwoman of Indian origin on Mauritius, executed a series of notarial acts which revealed that she possessed a small fortune in cash assets as well as slaves and substantial landed property in one of the island’s rural districts. The life of this former slave between 1776, when she first appears in the archival record, and her death in 1804 provides a vantage point from which to gain a subaltern perspective on aspects of Mascarene social and economic history, as well as developments in the wider Indian Ocean world during the late eighteenth and early nineteenth centuries. Marie Rozette’s life history challenges the notion that free persons of color in Mauritius were little more than an “unappropriated” people, and invites us to consider how supposedly marginalized individuals were able to cross various socio-economic and cultural boundaries. More specifically, her life affords an opportunity to consider the ways in which class, ethnicity, and gender, as well as race, interacted to create a distinctive Creole society in Mauritius, the nature and dynamics of which bear directly on our knowledge and understanding of the free colored experience elsewhere in the European colonial slave plantation world.

    Why do people fight wars? Following the devastation of the Second World War, this question became particularly pressing. Postwar scholars in the human sciences, from political science to anthropology, investigated the role of human nature in the causes of war even as they debated the very meaning of human nature itself. Among the wide-ranging efforts of postwar social and behavioral scientists to explain the causes of war, research on primate aggression became a compelling approach to studying the evolution of human warfare. In contrast, primatologist Frans de Waal's popular and scientific publications on primate reconciliation emphasized the naturalness of conflict resolution and peacemaking, thereby providing a counterpoint to the pessimism of aggression research while simultaneously shoring up the logic of simian analogy. De Waal's popular books heralded the "make love, not war" bonobo as humans' evolutionary next-of-kin and contributed to raising public interest in bonobos during the late twentieth century, although the apes' popular reputation subsequently exceeded the scientific discourse about them.

    An earthquake of magnitude 7.3 Mw occurred on 18th January 2011 in Southwestern Pakistan, Baluchistan province (Dalbadin Region). The area has complex tectonics due to interaction of Indian, Eurasian and Arabian plates. Both thrust and strike slip earthquakes are dominant in this region with minor, localized normal faulting events. This earthquake under consideration (Dalbadin Earthquake) posed constraints in depth and focal parameters due to lack of data for evaluation of parameters from Pakistan, Iran or Afghanistan region. Normal faulting mechanism has been proposed by many researchers for this earthquake. In the present study the earthquake was relocated using the technique of travel time residuals. Relocated coordinates and depth were utilized to calculate the focal mechanism solution with outcome of a dominant strike slip mechanism, which is contrary to normal faulting. Relocated coordinates and resulting mechanism are more reliable than many reporting agencies as evaluation in this study is augmented by data from local seismic monitoring network of Pakistan. The tectonics in the area is governed by active subduction along the Makran Subduction Zone. This particular earthquake has strike slip mechanism due to breaking of subducting oceanic plate. This earthquake is located where oceanic lithosphere is subducting along with relative movements between Lut and Helmand blocks. Magnitude of this event i.e. Mw = 7.3, re evaluated depth and a previous study of mechanism of earthquake in same region (Shafiq et al., 2011) also supports the strike slip movement.

    Pakistan has undergone massive changes in its federal structure under the 18th Constitutional Amendment. To gain insights that will inform reform plans, we assessed several aspects of health-systems performance in Pakistan. Some improvements were noted in health-systems performance during the past 65 years but key health indicators lag behind those in peer countries. 78·08% of the population pay out of pocket at the point of health care. The private sector provides three-quarters of the health services, and physicians outnumber nurses and midwives by a ratio of about 2:1. Complex governance challenges and underinvestment in health have hampered progress. With devolution of the health mandate, an opportunity has arisen to reform health. The federal government has constitutional responsibility of health information, interprovincial coordination, global health, and health regulation. All other health responsibilities are a provincial mandate. With appropriate policy, institutional, and legislative action within and outside the health system, the existing challenges could be overcome.

    The processes underlying the development of new populations are important for understanding how species colonize new territory and form viable long-term populations. Life-history-mediated processes such as Allee effects and dispersal capability may interact with climate variability and site-specific factors to govern population success and failure over extended time frames. We studied four disjunct populations of ponderosa pine in the Bighorn Basin of north-central Wyoming to examine population growth spanning more than five centuries. The study populations are separated from continuous ponderosa pine forest by distances ranging from 15 to >100 km. Strong evidence indicates that the initial colonizing individuals are still present, yielding a nearly complete record of population history. All trees in each population were aged using dendroecological techniques. The populations were all founded between 1530 and 1655 cal yr CE. All show logistic growth patterns, with initial exponential growth followed by a slowing during the mid to late 20th century. Initial population growth was slower than expectations from a logistic regression model at all four populations, but increased during the mid-18th century. Initial lags in population growth may have been due to strong Allee effects. A combination of overcoming Allee effects and a transition to favorable climate conditions may have facilitated a mid-18th century pulse in population growth rate.

  5. Synthesis of calcium antimonate nano-crystals by the 18th dynasty Egyptian glassmakers

    During the 18th Egyptian dynasty (1570-1292 B.C.), opaque white, blue and turquoise glasses were opacified by calcium antimonate crystals dispersed in a vitreous matrix. The technological processes as well as the antimony sources used to manufacture these crystals remain unknown. Our results shed a new light on glassmaking history: contrary to what was thought, we demonstrate that Egyptian glassmakers did not use in situ crystallization but first synthesized calcium antimonate opacifiers, which do not exist in nature, and then added them to a glass. Furthermore, using transmission electron microscopy (TEM) for the first time in the study of Egyptian opaque glasses, we show that these opacifiers were nano-crystals. Prior to this research, such a process for glassmaking has not been suggested for any kind of ancient opaque glass production. Studying various preparation methods for calcium antimonate, we propose that Egyptian craftsmen could have produced Ca2Sb2O7 by using mixtures of Sb2O3 or Sb2O5 with calcium carbonates (atomic ratio Sb/Ca=1) heat treated between 1000 and 1100°C. We developed an original strategy focused on the investigation of the crystals and the vitreous matrices using an appropriate suite of high-sensitivity and high-resolution micro- and nano-analytical techniques (scanning electron microscopy (SEM), X-ray diffraction (XRD), TEM). Synchrotron-based micro X-ray absorption near edge spectroscopy (μ-XANES) proved to be very well suited to the selective measure of the antimony oxidation state in the vitreous matrix. This work is the starting point for a complete reassessment not only of ancient Egyptian glass studies but more generally of high-temperature technologies used throughout antiquity.

    The present paper is based on a recently developed database including contemporary original, administrative, legal and private source materials (published and archival) as well as media reports related to the floods occurred on the lower sections of the Tisza river in Hungary, with special emphasis on the area of Szeged town. The study area is well-represented by contemporary source evidence from the late 17th century onwards, when the town and its broader area was reoccupied from the Ottoman Turkish Empire. Concerning the applied source materials, the main bases of investigation are the administrative (archival) sources such as town council protocols of Szeged and county meeting protocols of Csanád and Csongrád Counties. In these (legal-)administrative documents damaging events (natural/environmental hazards) were systematically recorded. Moreover, other source types such as taxation-related damage accounts as well as private and official reports, letters and correspondence (published, unpublished) were also included. Concerning published evidence, a most important source is flood reports in contemporary newspapers as well as town chronicles and other contemporary narratives. In the presentation the main focus is on the analysis of flood-rich flood-poor periods of the last ca. 330 years; moreover, the seasonality distribution as well as the magnitude of Tisza flood events are also discussed. Another important aim of the poster is to provide a short overview, in the form of case studies, on the greatest flood events (e.g. duration, magnitude, damages, multi-annual consequences), and their further impacts on the urban and countryside development as well as on (changes in) flood defence strategies. In this respect, especially two flood events, the great (1815-)1816 and the catastrophic 1879 flood (shortly with causes and consequences) - that practically erased Szeged town from the ground - are presented in more detail.

    A close examination of the literature suggests that the consistent relation between political and welfare state characteristics and infant mortality in the second half of the 20th century in wealthy countries may not be causal. The evolution of infant mortality since the late 19th century was studied in 17 wealthy countries classified according to political traditions, family policy model and period of infant mortality transition. The relation of public health expenditure and income inequality to infant mortality from 1980 to 2005 was also evaluated. The Social Democratic and Scandinavian countries, and those with the earliest transition in infant mortality, had the lowest infant mortality rates until the early 21st century, whereas the late democracies, the Southern European countries, and those in which the transition in infant mortality took place later, had the highest rates until the late 20th century. By the early 21st century, the differences in infant mortality were negligible. Three of the four Scandinavian countries were the first to achieve infant mortality transition, whereas the Southern European countries were the last. The relation between public health expenditure and infant mortality varied depending on the time period in which the analysis was made, and increased income inequality was associated with higher infant mortality. The relation between political and welfare state characteristics and infant mortality in previous studies probably reflects the historical moment in which the transition in infant mortality took place in each country. Methodological limitations do not allow inference of causality in the associations found between welfare state characteristics and infant mortality.

  8. Seismotectonics and seismic quietness of the Oranie region (Western Algeria): The Mascara earthquake of August 18th 1994, Mw = 5.7, Ms = 6.0

    The plate dynamics in the central western Mediterranean region is characterised by a collision between the Eurasian and African plates. In response to this dynamics, many systems of faults and folds having a NE-SW and E-W trending have been generated along the Tellian Atlas of Algeria. The Oranie region (north western Algeria) has experienced some significant earthquakes in the last centuries, the most important one is that of Oran city on February 9th 1790, Io = XI which destroyed the town completely and caused the loss of many lives. Since 1790 no other event was so disastrous except that of August 18th 1994, Mw = 5.7, which struck Mascara province (Algeria) at 01 h 13 mn GMT. Since the beginning of this century the region has been dominated by a seismic quietness. Thus, no event with magnitude larger than 5.5 have occurred in this area. In relation with this recent event, a seismotectonic framework summarising the tectonic, seismicity and focal solution results is presented. The Maximum Observed Intensities Map (MOI) made for Algeria (Bezzeghoud et al., 1996) is also used to show that the Mascara region is located in an VIII-X intensity zone, which explain partially the casualties caused by the 18/08/1994 (Mw = 5.7) earthquake. This earthquake is not anomalous compared to historical records but is unusual compared to recorded seismicity of this century. The seismotectonic map made in this study and also the review of the focal solutions given by the EMSC, Harvard, and other authors shows that our event is probably associated with a source belonging to a system of faults located in the vicinity of the village of Hacine where the maximum damage was observed.

  10. In Search of an Audience: Popular Pharmacies and the Limits of Literate Medicine in Late Seventeenth- and Early Eighteenth-Century Russia.

    PubMed

    Griffin, Clare

    2015-01-01

    This article addresses the question of the limits of literate medicine in Europe, through an examination of the Russian literate medical world of the late seventeenth and early eighteenth centuries. Russian courtly medicine had been dominated by Western Europeans from the 1480s, but in the early eighteenth century new licensing arrangements solidified the presence of these foreigners in the wider Russian medical world. Foreign medical practitioners took advantage of this development, aiming works at an increasingly large proportion of Russian literate society. These works, along with satirical and religious works emulating or deriding medical texts, show how by the 1720s the limits of literate medicine in Russia lay not at the edges of official court medicine, but rather at the edges of literate society.

    The 18th and 19th centuries in England were characterised by a period of increasing industrialisation of its urban centres. It was also one of widening social and health inequalities between the rich and the poor. Childhood is well-documented as being a stage in the life course during which the body is particularly sensitive to adverse socio-economic environments. This study therefore aims to examine the relationship between health and wealth through a comprehensive skeletal analysis of a sample of 403 children (0-17 years), of varying socio-economic status, from four cemetery sites in London (c.1712-1854). Measurements of long bone diaphyseal length, cortical thickness, vertebral neural canal size, and the prevalence of a range of pathological indicators of health stress were recorded from the Chelsea Old Church (high status), St Benet Sherehog (middle status), Bow Baptist (middle status), and Cross Bones (low status) skeletal collections. Children from the low status Cross Bones site demonstrated deficient growth values, as expected. However, those from the high status site of Chelsea Old Church also demonstrated poor growth values during infancy. Fashionable child-care practices (e.g. the use of artificial infant feeds and keeping children indoors) may have contributed to poor infant health amongst high status groups. However, differing health risks in the lower status group revealed the existence of substantial health inequality in London at this time. © 2016 The Authors International Journal of Osteoarchaeology Published by John Wiley & Sons Ltd.

  12. Extraterrestrial Life as the Great Analogy, Two Centuries Ago and in Modern Astrobiology

    NASA Astrophysics Data System (ADS)

    Sullivan, Woodruff T.

    Mainstream ideas on the existence of extraterrestrial life in the late 18th and early 19th centuries are examined, with a focus on William Herschel, one of the greatest astronomers of all time. Herschel viewed all of the planets and moons of our solar system as inhabited, and gave logical arguments that even the Sun, and by extension all of the stars, was a giant planet fit for habitation by intelligent beings. The importance for astrobiology both two centuries ago and now of the type of inductive reasoning called "analogy" is emphasized. Analogy is an imperfect tool, but given that we have only one known case of life and of a life-bearing planet, it is very difficult to make progress in astrobiology without resorting to analogy, in particular between known life and possible other life. We cannot overcome the "N = 1 Problem" without resorting to this "Great Analogy" to guide our research.

    2012-01-01

    This study sets out to extend and challenge existing historiography on late eighteenth century British popular culture, customary sports, class and cultural identity, focusing upon the rural geo-political borderland of England. It suggests that prevailing class-based and more London-biased studies need to be balanced with more regionalist-based work, and shows the importance of northern regional leisure variants. The textual and historical analysis draws largely on the published works of a neglected working-class dialect poet, Robert Anderson, living and working in Cumberland, arguing that he represented a strain of ''bardic regionalism,'' a variant of Katie Trumpener’s ''bardic nationalism.''

    For centuries, ancient Egyptian Royal mummies have drawn the attention both of the general public and scientists. Many royal mummies from the New Kingdom have survived. The discoveries of the bodies of these ancient rulers have always sparked much attention, yet not all identifications are clear even nowadays. This study presents a meta-analysis to demonstrate the difficulties in identifying ancient Egyptian royal mummies. Various methods and pitfalls in the identification of the Pharaohs are reassessed since new scientific methods can be used, such as ancient DNA-profiling and CT-scanning. While the ancestors of Tutankhamun have been identified, some identities are still highly controversial (e.g., the mystery of the KV-55 skeleton, recently most likely identified as the genetic father of Tutankhamun). The meta-analysis confirms the suggested identity of some mummies (e.g., Amenhotep III, Thutmosis IV, and Queen Tjye). © 2016 Wiley Periodicals, Inc.

    The Sun, in the early seventeenth century was, as it always had been, the ultimate arbiter of time-measurement In the last quarter of the century however this role was called into question as the new precision of post-Huygenian clocks revealed that natural time and the artificial mean time of the clock were not the same. Initially the question was little understood by the general public. The paper examines some early attempts to explain why "Sun-time" in 1700 was no longer "true-time."

  19. ‘Looking as Little Like Patients as Persons Well Could’: Hypnotism, Medicine and the Problem of the Suggestible Subject in Late Nineteenth-Century Britain

    PubMed Central

    Chettiar, Teri

    2012-01-01

    During the late nineteenth century, many British physicians rigorously experimented with hypnosis as a therapeutic practice. Despite mounting evidence attesting to its wide-ranging therapeutic uses publicised in the 1880s and 1890s, medical hypnosis remained highly controversial. After a decade and a half of extensive medical discussion and debate surrounding the adoption of hypnosis by mainstream medical professionals – including a thorough inquiry organised by the British Medical Association – it was decisively excluded from serious medical consideration by 1900. This essay examines the complex question of why hypnosis was excluded from professional medical practice by the end of the nineteenth century. Objections to its medical adoption rarely took issue with its supposed effectiveness in producing genuine therapeutic and anaesthetic results. Instead, critics’ objections were centred upon a host of social and moral concerns regarding the patient’s state of suggestibility and weakened ‘will-power’ while under the physician’s hypnotic ‘spell’. The problematic question of precisely how far hypnotic ‘rapport’ and suggestibility might depart from the Victorian liberal ideal of rational individual autonomy lay at the heart of these concerns. As this essay demonstrates, the hypnotism debate was characterised by a tension between physicians’ attempts to balance their commitment to restore patients to health and pervasive middle-class concerns about the rapid and ongoing changes transforming British society at the turn of the century.

    2015-01-01

    Western observatories became scientific factories from the mid-19th century. Astrometry symbolized the transition to an industrious economy of scientific practices. The printing chronograph, which reduced the personal equations of the observers, was, first in the United States, then in England, the symbolic instrument of this transformation. In France, the initiatives of the astronomer Liais were prototypical. In the practices of the Hendaye Observatory, and thanks to the abbé Verschaffel, the printing chronograph made its definitive entry in French observatories at the beginning of the 20th century. Excessive centralization of French astronomy, the authoritarianism of Urbain Le Verrier, the director of the Paris Observatory, and the poor market for scientific instruments explain why the printing chronograph took root, belatedly, in France.

    PubMed

    Glover, Susan M

    2009-10-01

    Traditionally, models of resource extraction assume individuals act as if they form strategies based on complete information. In reality, gathering information about environmental parameters may be costly. An efficient information gathering strategy is to observe the foraging behavior of others, termed public information. However, media can exploit this strategy by appearing to supply accurate information while actually shaping information to manipulate people to behave in ways that benefit the media or their clients. Here, I use Central Place Foraging (CPF) models to investigate how newspaper propaganda shaped ore foraging strategies of late nineteenth-century Colorado silver prospectors. Data show that optimistic values of silver ore published in local newspapers led prospectors to place mines at a much greater distance than was profitable. Models assuming perfect information neglect the possibility of misinformation among investors, and may underestimate the extent and degree of human impacts on areas of resource extraction.

    This work presents the multidisciplinary investigation of the head of Nebiri (Museo Egizio, Turin S_5109), Chief of Stables, a high status elite person from the 18th Dynasty involving MDCT, 3D brain surface and facial reconstructions accompanied by a consideration of previously presented chemical analysis of the embalming materials found in fragments of bandages used on the head and viscera (lung) found in one of the four canopic jars. Comparison of the techniques used for the cosmetic treatment of Nebiri with those used in other elite and high status non-royal persons confirms the validity of the use of the term "high status elite" in the case of Nebiri. This case highlights the importance of using modern forensic techniques both to enhance new technologies of retrospective diagnosis on altered human remains and to increase knowledge of past populations.

  9. The role of deep processes in late 20th century subsidence of New Orleans and coastal areas of southern Louisiana and Mississippi

    Dokka, Roy K.

    2011-06-01

    Geodetic leveling observations from Biloxi, MS, to New Orleans, LA, and water level gauge measurements in the New Orleans-Lake Pontchartrain area were analyzed to infer late 20th century vertical motions. These data were used to test the validity of previous subsidence rate measurements and the models that predict the location and causes of subsidence. Water gauges attached to bridge foundations and benchmarks affixed to deep rods that penetrate Holocene strata subsided as much as 0.8 m locally between 1955 and 1995. The observed deep-seated subsidence far exceeds model predictions and demonstrates that shallow processes such as compaction and consolidation of Holocene sediments are inadequate by themselves to explain late 20th century subsidence. Deep-seated subsidence occurring east and north of the normal faults marking the Gulf of Mexico basin margin can be explained by local groundwater withdrawal, and regional tectonic loading of the lithosphere by the modern Mississippi River delta (MRD). Sharp changes in subsidence coincide with strands of the basin margin normal faults. Displacements are consistent with activity and show motions consonant with fault creep. Deep subsidence of the region to the south, including New Orleans, can be explained by a combination of groundwater withdrawal from shallow upper Pleistocene aquifers, the aforementioned lithospheric loading, and perhaps, nongroundwater-related faulting. Subsidence due to groundwater extraction from aquifers ˜160 to 200 m deep dominated urbanized areas and is likely responsible for helping to lower local flood protection structures and bridges by as much as ˜0.8 m.

    this study, we use IP25 and alkenone biomarker proxies to document the subdecadal variations of sea ice and sea surface temperature in the subpolar North Atlantic induced by the decadally paced explosive tropical volcanic eruptions of the second half of the thirteenth century. The short- and long-term evolutions of both variables were investigated by cross analysis with a simulation of the IPSL-CM5A LR model. Our results show short-term ocean cooling and sea ice expansion in response to each volcanic eruption. They also highlight that the long response time of the ocean leads to cumulative surface cooling and subsurface heat buildup due to sea ice capping. As volcanic forcing relaxes, the surface ocean rapidly warms, likely amplified by subsurface heat, and remains almost ice free for several decades.

    Ergotism is a horrendous disease with grotesque symptoms caused by ingesting specific ergot alkaloids. Mass poisoning episodes are attributable to consumption of grain - usually rye - infected with the fungus Claviceps purpurea. By focusing on possible cases of ergotism, we re-examine Norwegian history from the sagas through to the end of the seventeenth century. Our review - not intended to be exhaustive, or ex post facto to assign medical or psychiatric labels - draws attention to the very real possibility that many remarkable medical cases may have been the result of the ingestion of highly poisonous and psychoactive food substances. Where possible we highlight explanations given at the time - often rooted in religion or demonology - to explain the disease.

    This article examines the technological development of artillery production in Florence during the last two decades of the fifteenth century, before and after the assimilation of the most efficient French ordnance into Italian warfare. The study starts from the notes, drawings, accounts, and guns produced by Bonaccorso di Vettorio Ghiberti (1451-1516), the heir of the foundry of his illustrious ancestor Lorenzo di Cione (1378-1455). Data have been collected from the historical archives of the Istituto degli Innocenti, from the Biblioteca Nazionale Centrale of Florence, and from the Florentine State Archive. This article demonstrates the existence of a lively and reactive war-related industry in Renaissance Italy, which was aware of new ideas and new techniques. The article highlights, moreover, the leading role of public demand in fostering military innovations.

    Thirty-nine pregnant adult Wistar strain rats were randomly assigned to one of three exposure groups: 0, 0.75, or 1.50 Gy X-radiation total exposure. Animals were exposed from the 14th to the 18th days of gestation at 0, 0.15, or 0.30 Gy per day. At term, 15 rats were killed and morphologic analyses were completed. Twenty-four rats were allowed to deliver their offspring. On the first day of postnatal life, litters were reduced to a maximum of eight pups per litter, with equal numbers of male and female offspring wherever possible. A total of 187 pups were observed for the age of acquisition of five reflexes (air righting, surface righting, visual placing, negative geotaxis, auditory startle) and the appearance of four physiologic markers (pinna detachment, eye opening, vaginal opening, testes descent). There was significant dose-related weight reduction in term fetuses and offspring throughout the 86-day postnatal period. Postnatal growth rate (g gained/day) was unaffected. Adult offspring brain and gonadal weight and organ weight:body weight ratios were reduced. Using the PAC50 methodology, dose-related alterations occurred in the acquisition of several reflexes. All physiologic markers exhibited a dose-related delay in appearance. These results indicate that fractionated exposure to X-radiation during the fetal period in the rat results in dose-dependent alterations in postnatal growth and physiologic development. These studies are important for our understanding of the long-range effects of prenatal exposure to ionizing radiation late in gestation.

  14. Frequency and patterning of bone trauma in the late medieval population (13th-16th century) from Dugopolje, southern Croatia.

    PubMed

    Novak, Mario; Slaus, Mario

    2012-07-01

    The aim of this paper is to test the hypothesis of an increased level of interpersonal violence in Dugopolje during the late medieval period as testified by written sources. In order to accomplish this, an analysis and comparison of frequencies and patterning of long bone and craniofacial fractures between sex and age categories in the Dugopolje skeletal sample was performed. In total 209 excellently preserved adult skeletons were analysed: 111 males and 98 females. The total long bone fracture frequency is 1.5% (29/1910) with a significantly higher frequency in males compared to females. Most of the long bone injuries occurred as a result of accidents, probably due to rugged mountainous terrain, while a certain portion of trauma resulted from deliberate violence. Significantly higher fracture frequencies in males could be a result of a strict sexual division of labour where males performed more physically demanding and risky tasks, as witnessed by historical sources. 26 out of 119 complete adult crania (21.8%) exhibit skeletal trauma with significantly higher frequencies in males. Perimortem trauma was observed in one individual while antemortem healed sharp force lesions were registered in five individuals (all males). The predominance of frontal craniofacial injuries, as well as the presence ofperimortem trauma and sharp force lesions, suggests the presence of deliberate violence in this community. Although the indicators of deliberate violence were recorded predominantly in males, suggesting that intentional violence in Dugopolje was exclusively males' prerogative, the presence of nasal fracture in a female skeleton might point to a male towards female violence. Presented bioarchaeological data are in accordance with the written documents thus corroborating the claims of an increased level of deliberate interpersonal violence in the late medieval population from Dugopolje.

    Campanella, Sara

    2016-01-01

    Ichthyological investigations and technological advancements, such as the laying of submarine telegraph cables, promoted new dredging methods in the second half of the 19th century. In contrast to the idea of a lifeless deep ocean (Edward Forbes' azoic hypothesis), the discovery of deep water fauna and the challenge of defining its systematics opened up new theoretical perspectives. In this frame, which was already marked by the impact of Darwin's theory, naturalistic surveys in freshwater environments in western Switzerland intertwined with those of oceanographic expeditions. The study of the fauna in the depths of subalpine lakes by the Swiss savant François-Alphonse Forel was one of the most striking examples of this turning point, because the relatively recently evolution of its freshwater fauna allowed him to investigate: (a) the role of isolation, (b) the progressive differentiation of species from a common ancestor, and (c) the constitution of a species-specific category in form transition, from a genealogical viewpoint to an ecological one.

  16. Mechanism, vitalism and organicism in late nineteenth and twentieth-century biology: the importance of historical context.

    PubMed

    Allen, Garland E

    2005-06-01

    The term 'mechanism' has been used in two quite different ways in the history of biology. Operative, or explanatory mechanism refers to the step-by-step description or explanation of how components in a system interact to yield a particular outcome (as in the 'mechanism of enzyme action' or the 'mechanism of synaptic transmission'). Philosophical Mechanism, on the other hand, refers to a broad view of organisms as material entities, functioning in ways similar to machines--that is, carrying out a variety of activities based on known chemical and physical processes. In the early twentieth century philosophical Mechanism became the foundation of a 'new biology' that sought to establish the life sciences on the same solid and rigorous foundation as the physical sciences, including a strong emphasis on experimentation. In the context of the times this campaign was particularly aimed at combating the reintroduction of more holistic, non-mechanical approaches into the life sciences (organicism, vitalism). In so doing, Mechanists failed to see some of the strong points of non-vitalistic holistic thinking. The two approaches are illustrated in the work of Jacques Loeb and Hans Spemann.

    Samples collected from 1965 onward were also compared with those from 1998 to investigate how the distribution of benthic foraminifera in Central Bay has changed over the latter half of the 20th Century, particularly in response to the invasion by Trochammina hadai. In 1998, T. hadai was recovered at 46 of 55 sites in Central Bay, comprising from 0.3 to 97% (mean = 23%) of the foraminiferal fauna. With the species’ affiliation for shallow environments, it is not unexpected that it dominated the fauna of the Shallow Subtidal Biofacies (68-97%, mean = 77%) and was also a significant component of the Intermediate Subtidal Biofacies (7-51%, averaging 28%). In the deeper waters west of Alcatraz Island, the abundance of T. hadai was significantly less (mean = 8%), most likely reflecting allochthonous specimens that were the result of post-mortem transport. A cluster analysis clearly distinguishes pre- and post-invasion biofacies, illustrating how dominant T. hadai has become in Central Bay.

  18. [Psychophysical parallelism. On a discursive figure in the field of scientific changes in the late 19th century].

    The article traces the rise and fall of "psychophysical parallelism" - which was the most advanced scientific formulation of the mind / body relationship in the second half of the 19th century - through an interdisciplinary and broad geographical spectrum. It sheds light on the extremely different positions that rallied round this discursive figure, ranging from Fechner, Hering, Mach, Wundt, Bain, Hughlings Jackson, and Taine to Freud and Saussure. The article develops the thesis that the psychophysical parallelism functioned as a 'hot zone' within and a symptom of the changes in the order of sciences at that time. Against that background, the criticism of the psychophysical parallelism which became prominent around 1900 (Stumpf, Busse, Bergson, Mauthner et. al.) indicates the cooling of this 'hot zone' and the establishment of a new order within the scientific disciplines. The article pays particular attention to the position of this figure in contemporaneous language theories. Its basic assumption is that the relationship between the body and the psyche is itself constituted by language.

    Tide gauges, located along the world's coastlines, represent one of the most important data sources with information about sea level change back into the 17th century, bridging the gap between paleo proxies and modern remote sensing data sources. While the worldwide coverage of tide gauges has increased considerably since the mid-20th century, there are only a few gauges available providing information about regional sea level changes before 1900. Furthermore, these tide gauge measurements are often contaminated by local vertical land movements (VLM) resulting from tectonic processes or local anthropogenic interventions. Such non-climatic effects need to be removed from the raw data to uncover climate signals, which are important, for instance, for answering the question whether and when sea level started to accelerate from the nearly constant rates over the past 2000 years. Here we focus on one of these long tide gauge records: Cuxhaven, which is located in the German Bight and provides uninterrupted digital time series of tidal high and low water levels since 1843. The record has been extensively studied during the past decades with respect to regional and global sea level rise. However, a question that still remains is the role of local subsidence before 1900 at the lighthouse of Cuxhaven, located close to the tide gauge. In 1855 Lentz installed a granite height mark at the lighthouse, which was later used as a proxy for VLMs of the tide gauge itself. The height of the control mark was derived by a levelling between Hamburg and Cuxhaven. These levellings were repeated five times between 1855 and 1900 and later evaluated by Siefert and Lassen (1985) with respect to the role of local subsidence. Based on a linear regression of individual levellings Siefert and Lassen (1985) concluded that the lighthouse subsided by an average rate of 2.8 mm/yr (1855-1875: 4.2 mm/yr; 1876-1890: 2 mm/yr; 1890-1900: 1.2 mm/yr). However, due to the massive uncertainties of these early

    Italy has a very important role in the development of meteorological observations. Consequently, a heritage of data of enormous value has been accumulated in Italy over the last three centuries. However, only a small fraction of Italian data is available in computer readable form and the available records mainly concern temperature, precipitation and pressure. Within this context, we set up a project to recover as much as possible cloudiness Italian records. The goal is to consider total cloud cover (TCC), low and middle cloud cover, and cloud types. The data source we are using include the former national central office for meteorology (now CRA-CMA), the national air force meteorological and climatological service and some of the oldest Italian observatories as Milan, Rome, Turin and Venice. The database contains sub-daily (from 3 to 8 observations per day for each station) information about TCC but also about the amount and the type of low, middle and high cloud in the sky. The oldest records start at about 1858 and about 30 records start in the 1880s. Currently quality check and test for temporal homogeneity is in progress. Then the monthly records will be completed by means of the neighboring records and averaged in order to get national and regional records for Italy and its main climatic areas. This new dataset will be presented and the results of the first analyses will be discussed. The study of cloudiness records for Italy is important also to better understand the behavior of sunshine duration, which shows a rather peculiar behaviour, especially in northern Italy. In this area, in fact, we observe a statistically significant increasing tendency during the period 1936-2103, that most publications do not report, as a consequence of a strong increase starting from the 1980 and a less evident decrease in the previous period.

    The middle and lower reaches of the Yangtze River basin have the most representative and largest concentration of freshwater lakes in China. However, the size and number of these lakes have changed considerably over the past century due to the natural and anthropogenic impact. The lakes, larger than 10 km(2) in size, were chosen from relief maps and remotely sensed images in 1875, 1950, 1970, 1990, 2000, and 2008 to study the dynamics of lakes in the middle and lower reaches of the Yangtze River basin and to examine the causes and consequences of these changes. Results indicated that there was a dramatic reduction in lake areas, which decreased by 7,841.2 km(2) (42.64 %) during the study period (1875-2008), and the number of lakes in this region changed moderately. Meanwhile, a large number of lakes in the middle and lower reaches of the Yangtze River basin were directly converted into paddy fields, ponds, building lands, or other land-use types over the study period. Therefore, all kinds of lake reclamation should be identified as the major driving factors for the loss of lake in this region. Furthermore, flooding, soil erosion, and sedimentation were also the main factors which triggered lake changes in different periods. Some wetland conservation and restoration projects have been implemented since the 1970s, but they have not reversed the lake degradation. These findings were of great importance to managers involved in making policy for the conservation of lake ecosystems and the utilization of lake resources.

    The Arctic is a highly sensitive region where numerous processes combine to generate the so-called Arctic amplification. One of the important climate feedbacks is related to the role of clouds. The limited observational record is one of the major challenges in the assessment of Arctic clouds. Here, a long-term climatology of cloudiness over the Norwegian, Barents and Kara Seas (NBK) based on visual surface observations is presented. Annual mean total cloud cover (TCC) over the NBK is almost equal over solid-ice (SI) and open-water (OW) parts of NBK (73±3% and 76±2% respectively). In general, TCC has higher intra- and inter-annual variability over SI than over OW. A decrease of TCC in the middle of the 20th century and an increase in the last few decades was found at individual stations and for the NBK as a whole. In most cases these changes are statistically significant with magnitudes exceeding the data uncertainty that is associated with the surface observations. The most pronounced trends are observed in autumn when the largest changes to the sea-ice concentration (SIC) occur. TCC over SI correlates significantly with SIC in the Barents Sea, with a statistically significant correlation coefficient between annual TCC and SIC of -0.38 for the period 1936-2013. Cloudiness over OW shows non-significant correlation with SIC. An overall increase in the frequency of broken and scattered cloud conditions, and a decrease in the frequency of overcast and cloudless conditions were found over OW. These changes are statistically significant and likely to be connected with the long-term changes of morphological types (an increase of convective and a decrease of stratiform cloud amounts).

    Museum collections have the potential to provide valuable information on the phenological response of organisms to climate change. This is particularly useful for those species for which few data otherwise exist, but also to extend time series to the period before other observational data are available. To test this potential, we analysed data from 2,630 specimens of four species of British butterflies (Anthocharis cardamines, Hamearis lucina, Polyommatus bellargus and Pyrgus malvae), collected from 1876 to 1999 and stored in the Natural History Museum, London, UK (NHM). In A. cardamines, first-generation P. bellargus and P. malvae, we found that there was a strong significant negative relationship between spring temperature and 10th percentile collection dates, which approximates mean first appearance date, and median collection date, which approximates mean flight date. In all four species, there was a significant negative relationship between the 10th percentile collection date and the length of the collection period, which approximates flight period. In second-generation P. bellargus, these phenological measurements were correlated with summer temperature. We found that the rates of phenological response to temperature, based on NHM data, were similar to, or somewhat greater than, those reported for other organisms based on observational data covering the last 40 years. The lower rate of phenological response, and the significant influence of February rather than March or April temperatures, in recent decades compared with data from earlier in the twentieth century may indicate that early emerging British butterfly species are currently approaching the limits of phenological advancement in response to recent climate warming.

    This article examined i) how traditional medico-pharmaceutical custom from the late 19th century influenced such changes, ii) how medical laws of Daehan Empire and early colonial period influenced the differentiation of medico-pharmaceutical profession, and iii) what the responses of medico-pharmaceutical professionals were like, and arrived at following conclusions. First, in late Chosun, there was a nationwide spread of pharmacies (medicine room, medicine store) as general medical institutions in charge of prescription and medication as well as diagnosis. Therefore, Koreans' perception of Western medicine was not very different from that of traditional pharmacy. Second, Western pharmacies were established by various entities including oriental doctors, Western doctors and drug manufacturers.Their business ranged from medical consultation, prescription, medication and drug manufacture. This was in a way the extension of traditional medico-pharmaceutical custom, which did not draw a sharp line between medical and pharmaceutical practices. Also, regulations on medical and pharmaceutical business of Daehan Empire did not distinguish oriental and Western medicine. Third, clinics attached to pharmacy began to emerge after 1908, as some Western pharmacies that had grown their business based on selling medicine began to hire doctors trained in Western medicine. This trend resulted from Government General's control over medico-pharmaceutical business that began in 1908, following a large-scale dismissal of army surgeons trained in medical schools in 1907. Fourth, as specialization increased within medico-pharmaceutical business following the colonial medical law in early 1910s, such comprehensive business practices as Western pharmacy disappeared and existing businesses were differentiated into dealers of medical ingredients, drug manufacturer, patent medicine businessmen and herbalists. And private practice gradually became the general trend by establishment of medical

    This study examines the impact of projected changes (A1B "marker" scenario) in emissions of four short-lived air pollutants (ozone, black carbon, organic carbon, and sulfate) on future climate. Through year 2030, simulated climate is only weakly dependent on the projected levels of short-lived air pollutants, primarily the result of a near cancellation of their global net radiative forcing. However, by year 2100, the projected decrease in sulfate aerosol (driven by a 65% reduction in global sulfur dioxide emissions) and the projected increase in black carbon aerosol (driven by a 100% increase in its global emissions) contribute a significant portion of the simulated A1B surface air warming relative to the year 2000: 0.2°C (Southern Hemisphere), 0.4°C globally, 0.6°C (Northern Hemisphere), 1.5-3°C (wintertime Arctic), and 1.5-2°C (˜40% of the total) in the summertime United States. These projected changes are also responsible for a significant decrease in central United States late summer root zone soil water and precipitation. By year 2100, changes in short-lived air pollutants produce a global average increase in radiative forcing of ˜1 W/m2; over east Asia it exceeds 5 W/m2. However, the resulting regional patterns of surface temperature warming do not follow the regional patterns of changes in short-lived species emissions, tropospheric loadings, or radiative forcing (global pattern correlation coefficient of -0.172). Rather, the regional patterns of warming from short-lived species are similar to the patterns for well-mixed greenhouse gases (global pattern correlation coefficient of 0.8) with the strongest warming occurring over the summer continental United States, Mediterranean Sea, and southern Europe and over the winter Arctic.

    Orthodontics had its beginnings in the time of the ancient Egyptians, who used crude metal bands and catgut, but it was not until the late 18th century that the first practical appliances came into use. These were fine-tuned during the early 1900s; today's mechanisms are merely refinements. Major changes occurred when practitioners--originally physicians--began turning their attention from cosmetic "regulating" to occlusion and stability, while empiricism gave way to objectivity and the scientific method. The purpose of this article is to review the history of orthodontics from antiquity to the modern era. The article is divided into chapters that will be presented serially in every other issue of the Journal.

    The objective of our study was to use MDCT to study brain treatment and removal (excerebration) as part of mummification of royal Egyptian mummies dated to the 18th to early 20th Dynasties and to correlate the imaging findings with the archaeologic literature. As part of an MDCT study of the Royal Ancient Egyptian Mummies Project, we analyzed CT images of the heads of 12 mummies dated to circa 1493-1156 BC (18th to early 20th Dynasties). We reconstructed and analyzed CT images for the presence of cranial defects, brain remnants, intracranial embalming materials, and nasal packs. We compared the CT findings of mummies dated to the 18th Dynasty with those dated to the 19th to early 20th Dynasties. The Akhenaten mummy was excluded because of extensive postmortem skull fractures. CT showed that no brain treatment was offered to three mummies (Thutmose I, II, and III) who dated to the early 18th Dynasty and was offered to the eight mummies who dated later. The route of excerebration was transnasal in eight mummies; an additional suspected route was via a parietal defect. CT showed variable appearances of the intracranial contents. There were larger volumes of cranial packs and more variability in the appearances of the cranial packs in the royal mummies dated to the 19th to 20th Dynasties than in those dated to the 18th Dynasty. MDCT shows variations in brain treatment during mummification of royal Egyptian mummies (18th-20th Dynasties). This study sets a template for future CT studies of the heads of ancient Egyptian mummies and focuses on the key elements of cranial mummification in this ancient era.

    For many centuries, unwed mothers in southern Italy were forced to surrender their infants because of a number of social, religious, economic, and political pressures. This study focuses on the policies and practices that were in place in southern Italy regarding illegitimate infants in the late nineteenth century. A detailed analysis of the policies and practices present in the town of Forio d'Ischia during the 20-year period 1880-1899 is also presented. During these two decades, there were 37 illegitimate live births representing 0.70% of the 5249 live births recorded in this town. Although small in number, these illegitimate births, referred to as spuri in Italian, from the Latin spurius, meaning bastard, were managed by standard predetermined procedures. These included anonymity for the parents, the transfer of such infants to an official town receiver of foundlings, and their transport to Naples' orphanage, the Real Casa Santa dell'Annunziata. This orphanage maintained fairly detailed records about the children who were delivered to it. After a few days at the orphanage, infants were often entrusted to the care of external wet nurses, preferably outside of Naples. This was done in the belief that infant survival was better assured in more rural environments. The case of an illegitimate infant, Antonino Spinalbese, is presented in detail. Born on 14 February 1882 in the town of Forio d'Ischia, he was brought to the orphanage 4 days later. Following a two-day stay at the orphanage, he was entrusted to an external wet nurse, Michele Mondella, and her husband, Ciro Fiscale di Felice, a mariner in the town of Torre del Greco. The available evidence indicates that Antonino Spinalbese became a mariner like his stepfather. As a crew member of the passenger ship, Vulcano, he made three trips from Naples to New York City in 1922 and 1923.

    The initial eruption column of May 18th, 1980 reached nearly 30 km altitude and released 1017 joules of thermal energy into the atmosphere in only a few minutes. Ascent of the cloud resulted in forced intrusion of a giant umbrella-shaped cloud between altitudes of 10 and 20 km at radial horizontal velocities initially in excess of 50 m/s. The mushroom cloud expanded 15 km upwind, forming a stagnation point where the radial expansion velocity and wind velocity were equal. The cloud was initiated when the pyroclastic blast flow became buoyant. The flow reduced its density as it moved away from the volcano by decompression, by sedimentation, and by mixing with and heating the surrounding air. Observations indicate that much of the flow, covering an area of 600 km2, became buoyant within 1.5 minutes and abruptly ascended to form the giant cloud. Calculations are presented for the amount of air that must have been entrained into the flow to make it buoyant. Assuming an initial temperature of 450??C and a magmatic origin for the explosion, these calculations indicate that the flow became buoyant when its temperature was approximately 150??C and the flow consisted of a mixture of 3.25 ?? 1011 kg of pyroclasts and 5.0 ?? 1011 kg of air. If sedimentation is considered, these figures reduce to 1.1 ?? 1011 kg of pyroclasts and 1.0 ?? 1011 kg of air. ?? 1986.

    The mummies of Kha and his wife Merit were found intact in an undisturbed tomb in western Thebes near the ancient workers’ village of Deir el-Medina. Previous MDCT (this abbreviation needs spelling out) investigations showed that the bodies of Kha and Merit did not undergo classical royal 18th Dynasty artificial mummification, which included removal of the internal organs. It was, therefore, concluded that the retention of the viscera in the body, combined with an absence of canopic jars in the burial chamber, meant the couple underwent a short and shoddy funerary procedure, despite their relative wealth at death. Nevertheless, all internal organs - brain, ocular bulbs/ocular nerves, thoracic and abdominal organs - showed a very good state of preservation, which contradicts the previous interpretation above. In order to better understand the type of mummification used to embalm these bodies, both wrapped mummies were reinvestigated using new generation X-ray imaging and chemical microanalyses Here we provide evidence that both individuals underwent a relatively high quality of mummification, fundamentally contradicting previous understanding. Elucidated “recipes”, whose components had anti-bacterial and anti-insecticidal properties, were used to treat their bodies. The time and effort undoubtedly employed to embalm both Kha and Merit and the use of imported costly resins, notably Pistacia, do not support the previously held view that the two individuals were poorly mummified. Despite a lack of evisceration, the approach clearly allowed their in situ preservation as well as affording a fairly successful mummification. PMID:26200778

    In the late nineteenth and early twentieth centuries, the unspoken fear of syphilis played a significant role in the development of beliefs about female sexuality. Many women were afraid of sexual relationships with men because they feared contracting syphilis, which was, at that time, untreatable. Women also feared passing this disease on to their children. Women's sexual aversion, or repression, became a focus for Freud and his colleagues, whose theory of psychosexual development was based on their treatment of women. This article examines the case of Dora, the memoirs of Mabel Dodge Luhan and other sources to argue that the fear of syphilis was a significant factor in upper- and middle-class women's avoidance of heterosexual relationships. The fear of syphilis, in turn, became a significant factor in the psychoanalytic construction of female sexuality. The social suppression of the fear of syphilis has had a profound impact on theories of women's development. The implication for psychiatry is that our models of psychological development occur within a sociocultural milieu and cannot escape suppressed aspects of our culture.

    One or more of three intense and persistent droughts impacted some Native American cultures in the early-11th, middle-12th and late-13th centuries, including the Anasazi, Fremont, Lovelock, and Mississippian (Cahokian) prehistorical cultures. Tree-ring-based reconstructions of precipitation and temperature indicate that warm drought periods occurred between AD 990 and 1060, AD 1135 and 1170, and AD 1276 and 1297. These droughts occurred during minima in the Pacific Decadal Oscillation and may have been associated with positive values of the Atlantic Multidecadal Oscillation. Each of the Native American cultures was supported, to a greater or lesser degree, by precipitation-dependent resources. Both the Four Corners region and Cahokia were sites of intense growth between about AD 1050 and 1130, and by AD 1150, cultures in both regions were undergoing stress. By AD 1300 the Anasazi and Fremont cultures had collapsed and their residual populations had either left their homelands or withered. In the case of Fremont populations, the AD 990-1060 drought may have had the greatest impact. This drought also may have affected the Anasazi, for it was at the end of this drought that some people from Chaco migrated to the San Juan River valley and founded the Salmon Ruin great house. Detailed data do not exist on the number of Lovelock habitation sites or populations over time; however, Lovelock populations appear to have retreated from the western Great Basin to California by AD 1300 or shortly thereafter.

    Study Objectives: To publish the first English translations, with commentary, of the original reports describing narcolepsy and cataplexy by Westphal in German (1877) and by Gélineau in French (1880). Methods: A professional translation service translated the 2 reports from either German or French to English, with each translation then being slightly edited by one of the authors. All authors then provided commentary. Results: Both Westphal and Gélineau correctly identified and described the new clinical entities of cataplexy and narcolepsy, with recurrent, self-limited sleep attacks and/or cataplectic attacks affecting 2 otherwise healthy people. Narcolepsy was named by Gélineau (and cataplexy was named by Henneberg in 1916). The evidence in both cases is sufficiently convincing to conclude that they were likely each HLA-DQB1*0602 positive and hypocretin deficient. Conclusions: The original descriptions of narcolepsy and cataplexy are now available in English, allowing for extensive clinical and historical commentary.

    Historical perspectives on fisheries and related human behaviour provide valuable information on fishery resources and their exploitation, helping to more appropriately set management targets and determine relevant reference levels. In this study we analyse historical fisheries and fish trade at the north-eastern Baltic Sea coast in the late 17th century. Local consumption and export together amounted to the annual removal of about 200 tonnes of fish from the nearby sea and freshwater bodies. The fishery was very diverse and exploited altogether one cyclostome and 17 fish species with over 90% of the catch being consumed locally. The exported fish consisted almost entirely of high-valued species with Stockholm (Sweden) being the most important export destination. Due to rich political history and natural features of the region, we suggest that the documented evidence of this small-scale fishery should be considered as the first quantitative summary of exploitation of aquatic living resources in the region and can provide a background for future analyses.

  17. Veterinary entomology, colonial science and the challenge of tick-borne diseases in South Africa during the late nineteenth and early twentieth centuries.

    This article provides an historical overview of developments in veterinary entomology during the late nineteenth and early twentieth centuries. During that period state employed entomologists and veterinary scientists discovered that ticks were responsible for transmitting a number of livestock diseases in South Africa. Diseases such as heartwater, redwater and gallsickness were endemic to the country. They had a detrimental effect on pastoral output, which was a mainstay of the national economy. Then in 1902 the decimating cattle disease East Coast fever arrived making the search for cures or preventatives all the more urgent. Vaccine technologies against tick-borne diseases remained elusive overall and on the basis of scientific knowledge, the South African state recommended regularly dipping animals in chemical solutions to destroy the ticks. Dipping along with quarantines and culls resulted in the eradication of East Coast fever from South Africa in the early 1950s. However, from the 1930s some ticks evolved a resistance to the chemical dips meaning that diseases like redwater were unlikely to be eliminated by that means. Scientists toiled to improve upon existing dipping technologies and also carried out ecological surveys to enhance their ability to predict outbreaks. Over the longer term dipping was not a panacea and ticks continue to present a major challenge to pastoral farming.

    During the years 1714 to 1721, Richard Bradley, who was later to become the first Professor of Botany at Cambridge University, proposed a unified, unique, living agent theory of the cause of infectious diseases of plants and animals and the plague of humans. Bradley's agents included microscopic organisms, revealed by the studies of Robert Hooke and Antony van Leeuwenhoek. His theory derived from his experimental studies of plants and their diseases and from microscopic observation of animalcules in different naturally occurring and artificial environments. He concluded that there was a microscopic world of "insects" that lived and reproduced under the appropriate conditions, and that infectious diseases of plants were caused by such "insects." Since there are structural and functional similarities between plants and animals, Bradley concluded that microscopic organisms caused human and animal infectious diseases as well. However, his living agent cause of infectious diseases was not accepted by the contemporary scientific society.

    The Herbarium of Moscow State University, Russia, possesses a relatively small (63 specimens), but historically interesting, collection of herbarium specimens linked with Carl Linnaeus (1707-1778). Some of these originally formed part of Linnaeus' own herbarium while others, although never his property, were nevertheless studied by him and may be original material for the typification of his plant names. This paper discusses the broad historical background to the gathering of these specimens, their study by Linnaeus and their subsequent fate. Specimens linked with Linnaeus have been encountered in each of the four largest historical collections of the Herbarium of Moscow State University, i. e., in the herbaria of J. F. Ehrhart, G. F. Hoffmann, C. B. von Trinius and C. L. Goldbach. Ehrhart's General Herbarium contains 31 sheets, which were more or less certainly collected or studied by Linnaeus. Ehrhart, a pupil of Linnaeus, received some specimens directly from the latter, while others came to him from Linnaeus filius, A. Dahl, and P. J. Bergius. Ehrhart's collections were purchased by G. F. Hoffmann, later, the first head of the Department of Botany at Moscow University, who took them to Russia. Hoffmann's General Herbarium contains three specimens that may be connected with Linnaeus. They were received from C. P. Thunberg, J. A. Murray, and an unknown person, respectively. At least five specimens from Trinius' collection, although certainly never seen by Linnaeus, are probable duplicates of material that was studied by him. Some of them are almost certainly iso-lectotypes of Linnaean names. Finally, 24 specimens linked with Linnaeus were found in Goldbach's herbarium. The majority of them were collected in the Lower Volga Region by J. Lerche and during the Second Kamchatka Expedition (Great Northern Expedition) by J. G. Gmelin and G. W. Steller.

    Classical violins produced by makers such as Antonio Stradivari and Guarneri del Gesu have long been considered the epitome of the luthier's art and the expressive tool of choice for the most celebrated violinists. It has been speculated these makers had access to wood that was unique in some way and that this was responsible for their acclaimed tonal characteristics. In an attempt to discern whether the above conjecture is true, we analyzed 17 modern and classical Dutch, German, Austrian and French violins by wood densitometry using computed tomography and correlated these results with our previous study of modern and Cremonese violins; in all studying 30 instruments of the violin family. In order to make this comparison possible we developed methods to cross calibrate results from different CT manufacturers using calibration wood pieces. We found no significant differences in median densities between modern and classical violins, or between classical violins from different origins. These results suggest that it is unlikely classical Cremonese makers had access to wood with significantly different wood density characteristics than that available to contemporaneous or modern makers.

    In 1765, the Irish parliament enacted legislation that established a nationwide hospital network funded by a mixture of taxation and philanthropic donations. The county infirmaries had a similar ethos to the British and Irish voluntary hospitals; only those with an admission ticket were admitted. The legislation also regulated the qualifications of the County Infirmary Surgeons who were authorised to run the infirmaries. This was the first statutory nationwide network of care in Ireland. No other country in contemporary Europe passed similar legislation. The Irish parliamentarians and Charles Lucas in particular appear to have been the impetus for this innovative legislation.

  17. The effect of aerosols and sea surface temperature on China's climate in the late twentieth century from ensembles of global climate simulations

    Over the late twentieth century, China has seen a strong increase in aerosol emissions, whose quantitative role for observed changes in surface solar radiation (SSR), surface air temperature (SAT), and precipitation remains debated. We use ensembles of transient sensitivity experiments with the global climate model ECHAM5 from the Max Planck Institute for Meteorology, Hamburg, Germany, combined with the Hamburg Aerosol Module to examine the effect of aerosols and prescribed, observation-based sea surface temperatures (SSTs) on the above variables. Observations and control experiments agree reasonably well in eastern China in terms of SSR dimming (-6 ± 2 W/m2/decade, 1960-2000; stronger than in models of the Coupled Model Intercomparison Project Phase 5, CMIP5), statistically nonsignificant summer SAT trend (1950-2005), and drying in summer from 1950 to 1990 (-2.5% to -3.5% per decade, essentially via reduction of convective precipitation). Other observed features are not reproduced by the model, e.g., precipitation increase in the 1990s in the Yangtze River valley or, from the 1960s onward, the strong winter warming in northern China and Mongolia and SSR dimming in western China. Aerosol effects are stronger for sulfur dioxide than for black and organic carbon and are more pronounced at lower model resolution. Transient SSTs are crucial for decadal-scale SAT variability over land, especially the strong warming in the 1990s, and, via SST forced reduction of cloud cover, for the ceasing of SSR dimming around the year 2000. Unforced cloud variability leads to relevant scatter (up to ±2 W/m2/decade) of modeled SSR trends at individual observation sites.

    Global-scale hydrological modeling faces multiple sources of uncertainty resulting from e.g. input data, model structure and model parameters, and it is of particular interest to investigate the sensitivity of a model to these influences. In the last years, a number of climate forcing data sets were developed for the global modelling community, and variable fields were found to differ significantly between the data-sets in certain regions. On the other side, human activity has a significant impact on the global hydrological cycle, e.g. through the construction of dams and the abstraction of water for irrigation purposes. In a global-scale hydrological modelling approach, human impact can be represented in various ways. It can be neglected (i.e. naturalized conditions without human impacts on river flow are simulated), kept at a constant level (e.g. present day conditions), or it can be simulated time-variant hence mimicking historical development of reservoirs and irrigation demand. Both uncertainties (forcing data, human impact) are influencing the response (i.e. output) of a water model, and it is assumed that the sensitivity of model outputs increases when combining the uncertainties of both input data. In this study we applied the WaterGAP global water availability and use model for 12 simulation setups resulting from four climate forcings (PGMFD v.2 (Princeton), GSWP3 (Global Soil Wetness Project 3), WATCH (WATCH Forcing Data, WFD), WATCH+WFD/ERAInterim) and three settings for human impact (naturalized, constant human impacts, time-varying human impacts). We assess the modeled water balance components for the late 20th century and evaluate the relative response to climate forcing as compared to human impact. Results are presented for selected large river basins as well as for the global scale.

    THE ANCIENT TIMES: Many early civilisations left testimonies about ancient times and resuscitation, as well. Some of them did it successfully and some of them did it less successfully; however, all of them wished to help a dying person and to bring him back to life. The first trustworthy note can be found in the Bible--Old Testament as a very realistic description of resuscitation of a child. THE MIDDLE AGES: The medieval scientists, Paracelsus and Vesalius, described first successful resuscitation attempts in the 15th and 16th century. These two men successfully applied ventilation methods by air inflation with blacksmith bellows. THE MODERN ERA: The first defibrillation was recorded in the 18th century in England, which was conducted by one of the volunteer society members. With the development of mechanics and techniques, the first precursors of modern respirators were introduced in the 19th century. The age of modern cardiopulmonary resuscitation began in the middle of 20th century, when Dr Peter Safar brought in the combination of artificial ventilation and chest compressions as the standard for implementing resuscitation. Adrenalin and defibrillation were introduced into the resuscitation techniques by Dr Redding and Dr Kouwenhaven, respectively; thus beginning the advance life support administration, which has been applied, with minor changes, until today.

    We present here the first result of a network on yearly resolutions of tree-ring cellulose δ18O measurements in Japan, containing 7 sites from sub-boreal (Hokkaido) to sub-tropical (Kagoshima) regions, 4 of which extend over 250 years. Because the tree-ring δ18O directly reflects δ18O of precipitation (water vapor) and local relative humidity without any large biological effects, it is one of the most promising proxies in the tree ring for reconstruction of past water cycles. Although it is necessary to clarify spatial pattern of tree-ring δ18O variations for reconstruction of past water cycles, it has never been tried outside of Europe or North America. Japanese islands are located between Eurasian continents and Pacific Ocean and partly influenced by East Asian Summer Monsoon, in which δ18O of precipitation shows minimum in summer, opposite to high latitudes such as Europe. There are some common characteristics in short and long-term variability of the tree-ring δ18O in Japan. Short-term variations in tree-ring δ18O are well correlated with those of local summer relative humidity near the sample sites, among which southwestern and northeastern Japan can be categorized into different groups according to their inter-annual variability. There is a long-term decreasing trend of the tree-ring δ18O from the 18th century, possibly reflecting the gradual enhancement of East Asian Summer Monsoon after Little Ice Age, but it increased again after late 19th or early 20th centuries at most sites due to regional decreases in relative humidity with global warming. In the 18th century, abrupt decadal-scale drops in the tree-ring δ18O were often observed at some sites only in southwestern Japan, possibly showing short-term enhancements of Asian Summer Monsoon during Little Ice Age.

    The aim of this article is to show how the Portuguese welfare system was organized and how it survived for several centuries. It was rebuilt by the monarchy in the late 15th century, a process that coincided with the birth of the Misericordias under the protection of the King. After the Council of Trent, these fraternities ran the health system, which was financed by people who believed in the power of perpetual Masses to evade Purgatory. These institutions were run by the political elite, who exploited them for their own benefit. The article also analyses the main measures taken by the state in the 18th century to change the old and weak system of public care. These laws were ineffectual and unable to change the real situation: the Misericordias were alone--the elite had run away when money was short--and they received no support from the public purse or from the faithful, who at that time had less faith in the perpetual Mass.

  6. Modeling the potential contribution of land cover changes to the late twentieth century Sahel drought using a regional climate model: impact of lateral boundary conditions

    Wang, Guiling; Yu, Miao; Xue, Yongkang

    2016-12-01

    This paper investigates the potential impact of "idealized-but-realistic" land cover degradation on the late twentieth century Sahel drought using a regional climate model (RCM) driven with lateral boundary conditions (LBCs) from three different sources, including one re-analysis data and two global climate models (GCMs). The impact of land cover degradation is quantified based on a large number of control-and-experiment pairs of simulations, where the experiment features a degraded land cover relative to the control. Two different approaches of experimental design are tested: in the 1st approach, the RCM land cover degradation experiment shares the same LBCs as the corresponding RCM control, which can be derived from either reanalysis data or a GCM; with the 2nd approach, the LBCs for the RCM control are derived from a GCM control, and the LBCs for the RCM land cover degradation experiment are derived from a corresponding GCM land cover degradation experiment. When the 1st approach is used, results from the RCM driven with the three different sources of LBCs are generally consistent with each other, indicating robustness of the model response against LBCs; when the 2nd approach is used, the RCM results show strong sensitivity to the source of LBCs and the response in the RCM is dominated by the response of the driving GCMs. The spatiotemporal pattern of the precipitation response to land cover degradation as simulated by RCM using the 1st approach closely resembles that of the observed historical changes, while results from the GCMs and the RCM using the 2nd approach bear less similarity to observations. Compared with the 1st approach, the 2nd approach has the advantage of capturing the impact on large scale circulation, but has the disadvantage of being influenced by the GCMs' internal variability and any potential erroneous response of the driving GCMs to land degradation. The 2nd approach therefore requires a large ensemble to reduce the uncertainties derived

  7. Urban land for a growing city at the banks of a moving river: Vienna's spread into the Danube island Unterer Werd from the late 17th to the beginning of the 20th century.

    In the relation between urban development and the Viennese Danube different periods can be identified from the late 17th to the early 20th century. These periods were strongly intertwined with both the history of the river and the history of the city. Urban expansion into the floodplains is demonstrated in this paper by investigating the island Unterer Werd, next to the city centre. In the late 17th century the fluvial dynamic still hampered urban development on the island. First measures to stabilise the river banks and to protect buildings from floods were taken soon thereafter, but the majority of practices aimed at mitigating the risks and impacts of the frequent floods: inundation was a part of the arrangement and the main target was to minimise the potential impacts. This practice also prevailed after the 1830s, when urban expansion began to move into the north and northwest of the island and the Danube floodplains were considered an important land resource for the growing city. In connection with new technologies and available means to channelise the river, the relationship between Vienna and the Danube changed fundamentally. Urban development in the riverine landscape gained new momentum. This process was initiated before the Great Danube Regulation from 1870 to 1875 was completed, the rate of growth accelerated after 1875. The last decades of the 19th century mark a turning point in the urban development of Vienna, with expanding urban areas becoming dependent upon a well functioning and maintained flood protection system.

    Societies and ecosystems in northern Africa are strongly affected by the availability of water. As a consequence, long-term absence of rainfall has very dear effects on the ecosystems, as was dramatically shown in the 70'ies and 80'ies of the 20 century. Recent high-resolution reconstructions of Sahel palaeoclimate allow for new insights into these drastic climate variations and to disentangle the effects of the different components of the climate system on African climate change. In this study we extend the instrumental record of climate variability using a marine sediment core that was retrieved off the coast of Senegal, northwest Africa. The 530-cm long record covers the last 4,000 years continuously. A Pb age model allows for a matching of the proxy record with instrumental data. Specifically, variations in the grain-size distributions of the terrigenous sediment fraction, deconvolved with an end-member modelling algorithm (Weltje, 1997) are used to reconstruct rainfall variability on land. In addition, chemical data are used to study the effect of human-induced dust production throughout the late Holocene. We show that dust deposition is closely related to monsoonal precipitation in West Africa until the 17th century AD, followed by a sharp increase in dust deposition at the beginning of the 18th century. We hypothesise that this increase in dust mobilisation is related to the advent of commercial agriculture in the Sahel region.

    The observation of ultra high energy cosmic rays with 20 sq km array has started at Akeno. The preliminary results on energy spectrum and arrival direction of energies above 10 to the 18th eV are prsented with data accumulated for four years with the 1 sq km array, for two years with the 4 sq km array and for a half year with the new array. The energy spectrum is consistent with the previous experiments showing the flattening above 10 to the 18.5 eV.

    The process of professionalization in Germany was hindered by several factors: the tradition of denominational nursing, the increasing segregation in the field of nursing, the resistance against nurses' professionalization, the late and sporadic institutionalization of nursing schools, and the classification of nursing as "ärztlicher Heilhilfsberuf". On the basis of these five influencing factors this paper will discuss the development in Germany in comparison to the USA at the end of the 19th and early 20th centuries. The aim is to explain the differences in the process of professionalization in the German Reich and the USA which are rooted in that period.

    Objective. To study the computed tomography(CT) images of royal Ancient Egyptian mummies dated to the 18th to early 20th Dynasties for the claimed diagnoses of ankylosing spondylitis (AS) and diffuse idiopathic skeletal hyperostosis (DISH) and to correlate the findings with the archaeology literature.Methods. We studied the CT images of 13 royal Ancient Egyptian mummies (1492–1153 BC) for evidence of AS and DISH and correlated our findings with the archaeology literature.Results. The findings of the CT scans excluded the diagnosis of AS, based on the absence of sacroiliac joint erosions or fusion of the facet joints. Four mummies fulfilled the diagnostic criteria for DISH:Amenhotep III (18th Dynasty), Ramesses II, his son Merenptah, and Ramesses III (19th to early 20th Dynasties).The diagnosis of DISH, a commonly a symptomatic disease of old age, in the 4 pharaohs is in concordance with their longevity and active lifestyles.Conclusion. CT findings excluded the diagnosis of AS in the studied royal Ancient Egyptian mummies and brought into question the antiquity of the disease. The CT features of DISH during this ancient period were similar to those commonly seen in modern populations,and it is likely that they will also be similar in the future.The affection of Ramesses II and his son Merenptah supports familial clustering of DISH. The process of mummification may induce changes in the spine that should be considered during investigations of disease in ancient mummies.

    The need for understanding the natural range of climate variability in the monsoon regions of Asia - among the worldês most heavily populated and most dependent on agriculture - is critical for making sound planning decisions in the face of expected hydrological changes associated with global climate change. As part of a US National Science Foundation-funded project (Tree Ring Reconstructions of Asian Monsoon Climate Variability) we have produced climate-responsive tree-ring records from tropical Asia that span the past five centuries. We find compelling evidence for 18th century decadal-scale summer monsoon droughts that span from India to Vietnam. Historical records corroborate that periods of severe drought occurred across much of the region during this time, while speleothem and coral records suggest multiple decadal-scale droughts for much of the Little Ice Age period in India, and elevated Sea Surface Temperature (SST) during the 18th century for much of the tropical Pacific, respectively. Tropical Pacific SST anomalies are seen as one key component to monsoon variability over the study region, with El Ni?o and La Ni?a like conditions resulting in rainfall reductions and increases, respectively, with corresponding opposite-sign anomalies across much of western North America. Persistent anomaly trends in the SST fields can result in the kinds of decadal-scale variability our studies suggest, although this is not the entire story. We explore the role of the Interdecadal Pacific Oscillation (IPO), first defined in 1999 as a Pacific-wide measure of variability that is physically distinct from both the Pacific Decadal Oscillation (PDO) and the El Ni?o Southern Oscillation (ENSO), in contributing to protracted -mega-droughts" in the region related to weakening monsoon strength, as suggested by recent research. Interestingly, near-millennium-aged conifers from Vietnam and Laos have been located and much longer records are now being constructed. Of great interest is

    The relation between fertility and postmenopausal longevity is investigated for a sample of 1635 women from a historical (17th to 18th century) French-Canadian cohort who lived past the age of 50 years. We find that increased fertility is linked to increased rather than decreased postreproductive survival. Postreproductive life expectancy extension is found to be tied to late births. This finding sheds new light on the cost of reproduction and may be viewed as supporting a new paradigm that states that reproductive potential drives remaining longevity. The emerging reproductive potential concept complements the well-established cost of reproduction hypothesis. Alternative explanations for the observed association are also explored. A specific finding is that the degree to which mortality increases for 50-year-old mothers as a result of senescence is closely tied to the logarithm of the age of their youngest child. For example, 50-year-old mothers experience a mortality decrease of 38% and an increase of remaining lifetime of 3.93 years for every 10-fold decrease in the age of their youngest child. This amount of gain in remaining life expectancy would apply to a mother with a two-year-old child as compared with a mother with a 20-year-old offspring. We also find evidence for the existence of vulnerable periods in human life history that are characterized by phases of heightened mortality and are found to be tied to reproduction and senescence.

    2011-03-01

    Fifty clinical medical books written in the late 18th and the 19th centuries were categorized into four alternating types on the basis of the differences in composition and contents. The nosological type in the first period classified diseases into taxa, and dealt symptoms as diseases. The eclectic type in the second period contained both categories of nosological diseases and those of local diseases. The organ system type in the third period focused on the local diseases arranged in a systematic manner. The infection emphasis type put the infectious diseases at the beginning, followed by the local diseases in a systematic manner. The four types of clinical medical books evolved in accordance with the changes in clinical medicine in the 19th century, exemplified by the activities of the Parisian school, including those regarding pathological anatomy, laboratory medicine in the German universities, and discovery of pathogenic bacteria. When Western medicine was introduced in Japan, different stages of medicine, representing the four types, arrived at different times.

  18. The Criminal Corpse, Anatomists and the Criminal Law: Parliamentary Attempts to Extend the Dissection of Offenders in Late Eighteenth-Century England

    Ward, Richard M.

    2015-01-01

    In the later eighteenth century two schemes were introduced in Parliament for extending the practice of handing over the bodies of executed offenders to anatomists for dissection. Both measures were motivated by the needs of anatomy — including the improvement of surgical skill, the development of medical teaching in the provinces, and for conducting public anatomical demonstrations. Yet both failed to pass into law due to concerns about the possibly damaging effects in terms of criminal justice. Through a detailed analysis of the origins and progress of these two parliamentary measures — a moment when the competing claims of anatomy and criminal justice vied for supremacy over the criminal corpse — the following article sheds light on judicial attitudes to dissection as a method of punishment and adds to our understanding of why the dread of dissection would come to fall upon the dead poor (rather than executed offenders) in the nineteenth century.

    Despite the enormous personal and social cost Of substance abuse, there is very little knowledge with respect to the mechanisms by which these drugs produce addiction as well as to the mechanisms of toxicity. Similarly, there is a lack of effective therapeutic intervention to treat the drug abusers. In this respect, nuclear medicine could contribute significantly by helping to gather information using brain imaging techniques about mechanisms of drug addiction which, in turn, could help design better therapeutic interventions, and by helping in the evaluation and diagnosis of organ toxicity from the use of drugs of abuse. This volume contains six short descriptions of presentations made at the 18th Meeting of the American College of Nuclear Physicians -- DOE Day: Substance Abuse and Nuclear Medicine.

    The 19th century witnessed many advances in scientific enzymology and microbiology that laid the foundations for modern biotechnological industries. In the current study, we analyze the content of original lager beer samples from the 1880s, 1890s and 1900s with emphasis on the carbohydrate content and composition. The historic samples include the oldest samples brewed with pure Saccharomyces carlsbergensis yeast strains. While no detailed record of beer pasteurization at the time is available, historic samples indicate a gradual improvement of bottled beer handling from the 1880s to the 1900s, with decreasing contamination by enzymatic and microbial activities over this time span. Samples are sufficiently well preserved to allow comparisons to present-day references, thus yielding molecular signatures of the effects of 20th century science on beer production. Opposite to rather stable carbohydrate profiles, some aldehydes reach up to 40-fold higher levels in the historic samples as compared to present-day references. Copyright © 2015 Elsevier Ltd.

    2012-05-01

    Popular depictions of 20th-century American motherhood have typically emphasized the joy and fulfillment that a new mother can expect to experience on her child's arrival. But starting in the 1950s, discussions of the "baby blues" began to appear in the popular press. How did articles about the baby blues, and then postpartum depression, challenge these rosy depictions? In this article, we examine portrayals of postpartum distress in popular magazines and advice books during the second half of the 20th century to examine how the unsettling pairing of distress and motherhood was culturally negotiated in these decades. We show that these portrayals revealed a persistent reluctance to situate motherhood itself as the cause of serious emotional distress and a consistent focus on changing mothers to adapt to their role rather than changing the parameters of the role itself. Regardless of whether these messages actually helped or hindered new mothers themselves, we suggest that they reflected the rarely challenged assumption that motherhood and distress should not mix.

    Sakae Miki said Classified Emergency Materia Medica had been the dominant standard of herbology throughout Joseon Dynasty, and that Compendium of Materia Medica had only been accepted so lately that a few books used herbological result of it in the late Joseon Dynasty. But according to Visiting Old Beijing Diary written by Munjoong Seo in 1690, Compendium of Materia Medica was in fact introduced before the year 1712, the year Miki Sakae argued to be the year Compendium of Materia Medica was accepted to Joseon officially. Now, we can assume that the introducing year of Compendium of Materia Medica was faster than Miki Sakae's opinion by the following reasons; the effort of Joseon government and intellectuals to buy new books of Ming & Ching; the publishing year of the book for living in countryside regarded as the first citing literature of Compendium of Materia Medica. And the True Records of the Joseon Dynasty and many collections written by intellectuals in the 18th century show that the herbological knowledge from Compendium of Materia Medica had already spread to the corners of Joseon Dynasty. Thus we can make the following assumption: Classified Emergency Materia Medica and Compendium of Materia Medica had coexisted in the late Joseon Dynasty. Sakae Miki suggested 6 examples which used Compendium of Materia Medica in the late Joseon Dynasty. I reviewed two of them in this paper, Essentials of Materia Medica & Handbook of Prescriptions from Materia Medica. Essentials of Materia Medica quoted Compendium of Materia Medica briefly focusing clinical use, and Handbook of Prescriptions from Materia Medica also re-compiled Compendium of Materia Medica to practical use according to the form of Treasured Mirror of Eastern Medicine. It means that the results of Compendium of Materia Medica have been used positively, based on the herbology of materia medica from countryside. From this point of view, the hyphothesis there weren't any herbological progress after accepting

    The application of micro-Raman spectroscopy (μ-RS) and scanning electron microscopy (SEM)/energy dispersive X-ray spectrometer (EDS) to the research of pigments collected from Statues of Feixiange Cliff No. 67 and No. 69 niche of Tang Dynasty in China is reported. Five kinds of pigments were found in the experimental data, including black (carbon), white (gypsum + quartz), blue (lapis lazuli) and green (Paris green + Barium sulphate). After synthesized in 1814, Paris green was reported for a large import as a light and bright green pigment to paint architectures in China from the late 19th century. The analyzed blue pigment demonstrated the similar Raman spectra to the Lâjvardina blue glazed ceramics, which indicated lapis lazuli was an artificial product. This confirmed the painting of Feixiange Cliff in the early Republic of China as the historical record, and also reveals that some pigments were imported from abroad.

    2009-04-01

    In Western Hungary, phenological evidence such as the beginning of grape ripening, vine harvest, tithe collection dates and, to some extent, harvested amounts, can provide proxy based evidence for late spring-summer temperatures. These data are almost continuous from the early 17th century, with some sporadic observations from the late 16th century. Based on these historical vine and grain series, this presentation describes the current status of historical climatology in Hungary. We initially focus on town council protocols, tithe and town accounts and vine harvest dates from the town of Kőszeg (Western Hungary). The historical series correlate well, over the 18th-19th century period, with Buda May-July temperature series, the Vienna-Burgerspital series (developed by Strömmer, E. 2003), and shorter eastern Hungarian series (e.g. Kecskemét and Gyöngyös). We also present preliminary historical data from Sopron (60 km north of Kőszeg) which show the potential of extending the regional proxy information almost continuously back to the early 16th, and with sporadic data to the 15th century. The complicated nature of the data is described (e.g. with respect to the normality of the data distribution) and we present methods to transform and composite the data into homogenous, homoscedastic time-series that can be used for proxy based calibration. Finally, a preliminary May-July temperature reconstruction is described which was derived using methods commonly used in dendroclimatology. All series and analyses presented were developed within the framework of the EU project 'Millenium'.

    In this study, we simulated the regional climate over Northern East Asian (NEA) region focusing on South Korea for about 110 years (current: 1979-2010, future: 2019-2100 under 4 RCP scenarios) with a 12.5 km horizontal resolution using five regional climate models (RegCM4, WRF, HadGEM3-RA, GRIMs, SNURCM) and two ensemble methods. The simulation results of HadGEM2-AO provided from NIMR/KMA were used as boundary data for RCMs. In general, the five RCMs well simulated the spatial/seasonal variations for thetemperature and precipitation. In particular, the simulation skills of RCMs were clearly improved in both temperature and precipitation compared with that of HadGEM2-AO. However, their simulation skills had systematic error although the magnitudes of error were dependent on the RCMs, variables, seasons, and locations. The simple ensemble reduced the model biases, but most of the systematic biases were still remained. On the other hand, the weighted ensemble averaging using Taylor's skill score (WEA_Tay) clearly reduced the biases irrespective of variables and seasons in terms of mean climate. The temperature over NEA region in the late 21st century is projected to increase irrespective of locations, scenarios (+1.96~+4.85℃), and seasons with more warming at northern part of model domain. On the other hand, the precipitation changes are depended on the locations, scenarios and seasons. More detailed results for climate changes in the late 21st century under 4 RCP scenarios by five RCMs and ensembles will be discussed in presentation.

    Recent research on the professionalization of psychology at the end of the nineteenth century shows how objects of knowledge which appear illegitimate to us today shaped the institutionalization of disciplines. The veridical or telepathic hallucination was one of these objects, constituting a field both of division and exchange between nascent psychology and disciplines known as 'psychic sciences' in France, and 'psychical research' in the Anglo-American context. In France, Leon Marillier (1862-1901) was the main protagonist in discussions concerning the concept of the veridical hallucination, which gave rise to criticisms by mental specialists and psychopathologists. After all, not only were these hallucinations supposed to occur in healthy subjects, but they also failed to correspond to the Esquirolian definition of hallucinations through being corroborated by their representation of external, objective events.

    We synthesize existing evidence on the ecological history of the Florida Everglades since its inception ~7 ka (calibrated kiloannum) and evaluate the relative impacts of sea level rise, climate variability, and human alteration of Everglades hydrology on wetland plant communities. Initial freshwater peat accumulation began between 6 and 7 ka on the platform underlying modern Florida Bay when sea level was ~6.2 m below its current position. By 5 ka, sawgrass and waterlily peats covered the area bounded by Lake Okeechobee to the north and the Florida Keys to the south. Slower rates of relative sea level rise ~3 ka stabilized the south Florida coastline and initiated transitions from freshwater to mangrove peats near the coast. Hydrologic changes in freshwater marshes also are indicated ~3 ka. During the last ~2 ka, the Everglades wetland was affected by a series of hydrologic fluctuations related to regional to global-scale fluctuations in climate and sea level. Pollen evidence indicates that regional-scale droughts lasting two to four centuries occurred ~1 ka and ~0.4 ka, altering wetland community composition and triggering development of characteristic Everglades habitats such as sawgrass ridges and tree islands. Intercalation of mangrove peats with estuarine muds ~1 ka indicates a temporary slowing or stillstand of sea level. Although sustained droughts and Holocene sea level rise played large roles in structuring the greater Everglades ecosystem, twentieth century reductions in freshwater flow, compartmentalization of the wetland, and accelerated rates of sea level rise had unprecedented impacts on oxidation and subsidence of organic soils, changes/loss of key Everglades habitats, and altered distribution of coastal vegetation.

    A new high-resolution (0.9$^{\\circ}$x1.25$^{\\circ}$ in the horizontal) global tropospheric aerosol dataset with monthly resolution is generated using the finite-volume configuration of Community Atmosphere Model (CAM4) coupled to a bulk aerosol model and forced with recent estimates of surface emissions for the latter part of twentieth century. The surface emissions dataset is constructed from Coupled Model Inter-comparison Project (CMIP5) decadal-resolution surface emissions dataset to include REanalysis of TROpospheric chemical composition (RETRO) wildfire monthly emissions dataset. Experiments forced with the new tropospheric aerosol dataset and conducted using the spectral configuration of CAM4 with a T85 truncation (1.4$^{\\circ}$x1.4$^{\\circ}$) with prescribed twentieth century observed sea surface temperature, sea-ice and greenhouse gases reveal that variations in tropospheric aerosol levels can induce significant regional climate variability on the inter-annual timescales. Regression analyses over tropical Atlantic and Africa reveal that increasing dust aerosols can cool the North African landmass and shift convection southwards from West Africa into the Gulf of Guinea in the spring season in the simulations. Further, we find that increasing carbonaceous aerosols emanating from the southwestern African savannas can cool the region significantly and increase the marine stratocumulus cloud cover over the southeast tropical Atlantic ocean by aerosol-induced diabatic heating of the free troposphere above the low clouds. Experiments conducted with CAM4 coupled to a slab ocean model suggest that present day aerosols can shift the ITCZ southwards over the tropical Atlantic and can reduce the ocean mixed layer temperature beneath the increased marine stratocumulus clouds in the southeastern tropical Atlantic.

    The political problems in Late Roman Empire caused significant changes in the coin technology. The silver content dropped severely and a new technology, in all the mints operating around the Empire, was introduced. For the production of these coins, copper based quaternary alloys were used and their surface was covered by a silver amalgam plating layer. Hoards of these coins have been recovered in thousands from across the Empire, however, their treatment has been problematic. Both mechanical and chemical cleaning results in the damage or the complete destruction of the thin silver layer. The use of laser technology in the cleaning of works of art has a wide range of applications which includes metallic objects. The main aim of this work was to investigate the use of lasers in the cleaning of the thin silver plating layers found in late Roman coins. The optimisation of laser parameters was achieved through comparative cleaning tests by employing Nd:YAG (532 nm and 266 nm) laser systems. The cleaning results on the plated areas were characterised by optical microscopy, and SEM-EDX analysis. Following a systematic investigation and many cleaning trials on two different wavelengths and fluence values, optimum irradiation parameters were thoroughly demonstrated. Microscopic observations of the cleaned areas evidenced complete removal of the encrustation and high selectivity of the laser cleaning. Neither thermal or mechanical injuries, nor cuprite blackening were observed on the cleaned surfaces at the optimum laser cleaning technique, using 532 nm of the Nd: YAG laser.

    During the last two decades, the Arctic was put into the scientific focus as one of the most impacted regions worldwide concerning anthropogenic global warming. However, the warming between 1920 and 1940 proofs the importance of internal variability on yearly and decadal scale. Therefore, it is important to further investigate the role of external and internal forcings on the Arctic climate attribute process and causes leading to changes in the Arctic climate regime (Serreze & Barry 2009). Although much research effort was spent to understand the links and influences of and on the Arctic climate, there is still a need for further insights concerning this topic. Especially the results and discussion about anthropogenic global warming and Arctic amplification put the Arctic into the public and academic focus (Serreze & Barry 2011). However, the early 20th century Arctic warming, although discovered immediately, was scientifically forgotten until recently (Delworth & Knutson 2000, Bengtsson et al 2004, Grant et al 2009, Bekryaev et al 2010). The comparison of this earlier Arctic warming and the recent warming period grants a chance to deepen knowledge about the drivers of Arctic climate and can be used to evaluate the anthropogenic impact. The authors use the Twentieth Century Reanalysis (20CR) dataset and a nudged, reanalysis-driven Aerosol Global Circulation Model (A-GCM) to investigate the impact of atmospheric energy and aerosol fluxes into the Arctic during the 20th century. The 20CR dataset covers the period of 1871 - 2010 with a temporal resolution of 6hr and a spatial resolution of 2° x 2°. For the first time, this dataset (and ist 56 ensemble member) is used to compute the atmospheric energy flux, consisting of sensble heat, latent heat, potential energy and kinetic energy. The values are integrated around 70° N and between 1000 - 100 hPa. Aerosol fluxes for the same domain but for the years 1957 - 2000 are calculated based on the A-GCM nudged to the ECMWF

    The chance discovery of a 1.5-3.5 years old mummified girl presents a unique opportunity to further our understanding of health and disease among children in 19th Century San Francisco. This study focuses on carbon and nitrogen stable isotope signatures in serial samples of hair that cover the last 14 months of her life. Results suggest an initial omnivorous diet with little input from marine resources or C4 plants. Around six months before death δ15N starts a steady increase, with a noticeable acceleration just two months before she died. The magnitude of δ15N change, +1.5‰ in total, is consistent with severe undernourishment or starvation. Cemetery records from this time period in San Francisco indicate high rates of infant and child mortality, mainly due to bacterial-borne infectious diseases, about two orders of magnitude higher than today. Taken together, we hypothesize that the girl died after a prolonged battle with such an illness. Results highlight the tremendous impacts that modern sanitation and medicine have had since the 1800s on human health and lifespan in the United States.

  18. ‘No “Sane” Person Would Have Any Idea’: Patients’ Involvement in Late Nineteenth-century British Asylum Psychiatry

    In his 1895 textbook, Mental Physiology, Bethlem Royal Hospital physician Theo Hyslop acknowledged the assistance of three fellow hospital residents. One was a junior colleague. The other two were both patients: Walter Abraham Haigh and Henry Francis Harding. Haigh was also thanked in former superintendent George Savage’s book Insanity and Allied Neuroses (1884). In neither instance were the patients identified as such. This begs the question: what role did Haigh and Harding play in asylum theory and practice? And how did these two men interpret their experiences, both within and outside the asylum? By focusing on Haigh and Harding’s unusual status, this paper argues that the notion of nineteenth-century ‘asylum patient’ needs to be investigated by paying close attention to specific national and institutional circumstances. Exploring Haigh and Harding’s active engagement with their physicians provides insight into this lesser-known aspect of psychiatry’s history. Their experience suggests that, in some instances, representations of madness at that period were the product of a two-way process of negotiation between alienist and patient. Patients, in other words, were not always mere victims of ‘psychiatric power’; they participated in the construction and circulation of medical notions by serving as active intermediaries between medical and lay perceptions of madness.

    The Tien-Shan is one of the largest mountain belts in the world. Its deformation is dominated by intermontane basins bounded by active thrust and reverse faulting. The Tien-Shan mountain belt is characterized by a very high rate of seismicity along its margins as well as within the Tien-Shan interior. The study area of the here presented work, the western part of the Tien-Shan region, is currently seismically active with small and moderate sized earthquakes. However, at the end of 19th beginning of 20th century, this region was struck by a remarkable series of large magnitude (M>7) earthquakes, two of them reached magnitude 8. These large earthquakes occurred before the global digital seismic network was installed and therefore were recorded only by analog seismic instruments. The processing of the analog is complicated especially due to the digitization of the records - a very time-consuming and delicate part. Therefore a special set of techniques is developed and modern methods are adapted for the digitized instrumental data analysis. Here presented study evaluates the impact of large magnitude M>7.0 earthquakes, in the Tien-Shan region, on the overall regional tectonics. It also investigates the accuracy of previously estimated source parameters for those earthquakes, which were mainly based on macroseismic observations, and re-estimate them based on the instrumental data. Ten strongest and most interesting historical earthquakes in Tien-Shan region are analyzed with in presented work. With the developed techniques, the source parameters of these major earthquakes are determined and their impact on the regional tectonics was investigated. The large magnitudes of the earthquakes are confirmed by instrumental data. The focal mechanisms of these earthquakes were determined providing evidence for responsible faults or fault systems.

    During the eighties of the 19th century several physical education teachers who were engaged in physical therapy activities, so called 'heilgynasten', believed that only a solid organization of serious, educated and well-trained heilgymnasten could bring about a positive change in the situation at hand in the field of physical therapy. On September 1st 1889 the 'Genootschap ter beoefening van de Heilgymnastiek in Nederland' ('Society for practising heilgymnastiek in the Netherlands') was founded. The main aim of its members was to establish a state-exam, a public trainingschool as well as to ensure proper legislation for this 'new' profession. In this paper the focus of attention is on the founding of the 'Genootschap' and the reactions it provoked from organizations and practitioners in the fields of physical education and medicine during the first years of its existance. One could say that at first the 'Genootschap' was tolerated. Several well-known Dutch physicians joined the 'Genootschap' as 'extraordinary-member'. Very soon however, some physicians came to see the activities of this organization as a threat to the process of differentiation and specialization in the field of orthopaedic surgery that had just began. They emphasized that the 'heilgymnasten' who worked relatively independent from physicians in the field of physical therapy had no legal status; in fact they argued that these practitioners were actually breaking the law. A solution to these problems was sought through law-suits against 'heilgymnasten' to ensure that they would only practise physical therapy under supervision of physicians. In a next article the plight of one of the Dutch 'heilgymnasten', Hendrik Soeter, who can be considered as a 'victim' of this strategy, will be discussed in more detail. The Dutch 'heilgymnasten' did finally gain a legal status for their profession, but they had to wait for that untill more than fifty years after the foundation of the 'Genootschap'.

    To test the historically documented hypothesis of a general increase in deliberate violence in the eastern Adriatic from the antique (AN; 2nd-6th c.) through the early medieval (EM; 7th-11th c.) to the late-medieval period (LM; 12th-16th c.), an analysis of the frequency and patterning of bone trauma was conducted in three skeletal series from these time periods. A total of 1,125 adult skeletons-346 from the AN, 313 from the EM, and 466 from the LM series-were analyzed. To differentiate between intentional violence and accidental injuries, data for trauma frequencies were collected for the complete skeleton, individual long bones, and the craniofacial region as well as by type of injury (perimortem vs. antemortem). The results of our analyses show a significant temporal increase in total fracture frequencies when calculated by skeleton as well as of individuals exhibiting one skeletal indicator of deliberate violence (sharp force lesions, craniofacial injuries, "parry" fractures, or perimortem trauma). No significant temporal increases were, however, noted in the frequencies of craniofacial trauma, "parry" fractures, perimortem injuries, or of individuals exhibiting multiple skeletal indicators of intentional violence. Cumulatively, these data suggest that the temporal increase in total fracture frequencies recorded in the eastern Adriatic was caused by a combination of factors that included not only an increase of intentional violence but also a significant change in lifestyle that accompanied the transition from a relatively affluent AN urban lifestyle to a more primitive rural medieval way of life.

    Regional climate change projections for the last half of the twenty-first century have been produced for South America, as part of the CREAS (Cenarios REgionalizados de Clima Futuro da America do Sul) regional project. Three regional climate models RCMs (Eta CCS, RegCM3 and HadRM3P) were nested within the HadAM3P global model. The simulations cover a 30-year period representing present climate (1961-1990) and projections for the IPCC A2 high emission scenario for 2071-2100. The focus was on the changes in the mean circulation and surface variables, in particular, surface air temperature and precipitation. There is a consistent pattern of changes in circulation, rainfall and temperatures as depicted by the three models. The HadRM3P shows intensification and a more southward position of the subtropical Pacific high, while a pattern of intensification/weakening during summer/winter is projected by the Eta CCS/RegCM3. There is a tendency for a weakening of the subtropical westerly jet from the Eta CCS and HadRM3P, consistent with other studies. There are indications that regions such of Northeast Brazil and central-eastern and southern Amazonia may experience rainfall deficiency in the future, while the Northwest coast of Peru-Ecuador and northern Argentina may experience rainfall excesses in a warmer future, and these changes may vary with the seasons. The three models show warming in the A2 scenario stronger in the tropical region, especially in the 5°N-15°S band, both in summer and especially in winter, reaching up to 6-8°C warmer than in the present. In southern South America, the warming in summer varies between 2 and 4°C and in winter between 3 and 5°C in the same region from the 3 models. These changes are consistent with changes in low level circulation from the models, and they are comparable with changes in rainfall and temperature extremes reported elsewhere. In summary, some aspects of projected future climate change are quite robust across this set of

    The Palu-Koro fault is a left-lateral strike-slip fault in Sulawesi within the active triple junction generated by the ongoing fast convergence of the Pacific-Philippine plate, the Indo-Australian plate and the Sunda plate. There are densely populated areas that are susceptible to earthquakes occur along the fault, and the August 18th 2012, Mw6.3 earthquake is one of such events. To better understand this earthquake and the seismic hazard in the region, we estimated source parameters of this earthquake using the Cut and Paste (CAP) inversion method with regional broadband waveform data. Our results show that the best solution of this event is 339°, 71°, -16° and 11 km for strike, dip, rake and centroid depth, respectively. Inversions using stations within different distance ranges, i.e. 0-5, 0-10° and 0-20°, reveal consistent solutions, suggesting the robustness of our result, which is also in agreement with that from the other agencies, i.e. USGS and Global CMT. We further verify the centroid depth by modeling the depth phases recorded at the teleseismic distance, which also confirm the depth of 11km. Finally we analyzed the Coulomb stress caused by this earthquake and historical events to investigate the interaction between the earthquakes in the region. Our analysis also shows that the unclamping effect from the 1996 Mw7.9 megathrust in the Minahassa Trench promoted the occurrence of the 2012 Mw6.3 event. High slip-rate across the fault and Coulomb stress analysis suggest that more attention should be paid to the segments along the Palu-Koro fault that did not rupture in the previous earthquake circle.

    A careful inspection of the drawings and baked clay models created by the mineralogist Romé de L'Isle in the 18th century has revealed the existence of a number of intriguing forms with pentagonal symmetries. These forms cannot be classified in any of the 32 crystal classes. They can thus be considered the first crystallographic descriptions of polyhedral forms found in quasicrystals two centuries later. This paper presents a symmetry analysis of the fascinating drawings and clay models with pentagonal symmetries described in the book Cristallographie published in 1783 by Romé de L'Isle, as well as a comparison with quasicrystals recently synthesized. The paper also briefly discusses what could induce Romé de L'Isle to consider forms with pentagonal symmetries as plausible crystal forms.

  6. YI Suki's Yŏksimanpil and the Professional Identity of a Chung'in Medical Official in Eighteenth Century Chosŏn Korea.

    2013-08-01

    About one hundred years after the publication of Tongŭibogam (1613), a physician at the court YI Suki (1664-?) wrote a medical manuscript titled Yŏksimanpil (Miscellaneous Jottings on Medical Experiences and Tests, 1734). As indicated in its title, Yŏksimanpil was a medical essay composed of 130 medical case histories, drawing on what YI Suki himself had experienced in his medical practices. This paper examines the messages YI Suki in Yŏksimanpil tried to address to his fellow Korean doctors, and by doing so illuminates an aspect of the medicine in the late Chosŏn period. The argument goes that YI Suki wrote Yŏksimanpil as a vehicle for promulgating his professional identity as a bureaucratic physician who belonged to the network of the chung'in technical officials-a group of government technical functionaries in late Chosŏn Korea. Throughout the late Chosŏn period, the chung'in technical officials had been discriminated, institutionally and socioculturally, against the yangban literati, while their promotion to honored higher positions was blocked. It was in the late 17th and early 18th century that a group of chung'in officials tried to secure their sociocultural places for their professional activity, thus bringing to light their social and professional identity in Chosŏn society. A member of the network of the chung'in technical officials in the early 18th century, YI Suki was in an effort to position himself as a doctor somewhere between the medical tradition and the Confucian literary tradition. In these sociocultural contexts, we can see more clearly what YI Suki tried to speak of in his book and the historical meaning of the medical writing Yŏksimanpil. First, the way he practiced medicine was testing and confirming what the received medical textbooks had asserted (Chŭnghŏmkobang). This style of practicing medicine could be viewed as a reflection of the comprehensivity trait of bureaucratic court physicians network YI Suki belonged to. Also this

    The flanks of Mt St Helens volcano (MSH) are draped with thin, cross-stratified and stratified pyroclastic density current (PDC) deposits. These are known as the proximal bedded deposits produced during the May 18th, 1980 eruption of MSH. While the concentrated portions of the afternoon PDCs followed deep topographic drainages down the steep flanks of the volcano, the dilute overriding cloud partially decoupled to develop fully dilute, turbulent PDCs on the flanks of the volcano (Beeson, D.L. 1988. Proximal Flank Facies of the May 18, 1980 Ignimbrite: Mt. St. Helens, Washington.). The deposits along the flank thus vary greatly from those found in the pumice plain, which are generally thick, massive, poorly-sorted, block-rich deposits associated with the more concentrated portions of the flow (Brand et al, accepted. Dynamics of pyroclastic density currents: Conditions that promote substrate erosion and self-channelization - Mount St Helens, Washington (USA). JVGR). We explore the influence of topography on the formation of these dilute currents and influence of slope on the currents transport and depositional mechanisms. The deposits on steeper slopes (>15°) are fines depleted relative to the proximal bedded deposits on shallower slopes (<15°). Bedform amplitude and wavelength increase with increasing slope, as does the occurrence of regressive dunes. Increasing slope causes an increase in flow velocity and thus an increase in flow turbulence. The fines depleted deposits suggest that fine ash elutriation is more efficient in flows with stronger turbulence. The longer wavelength and amplitudes suggest that bedform morphology is directly related to flow velocity, an important finding since the controls on bedform wavelength and amplitude in density stratified flows remains poorly constrained. The occurrence of regressive dunes, often interpreted as high flow-regime bedforms, on steeper slopes relative to progressive dunes on shallower slopes further attests to the

    Urine has always interested and attracted the attention of people. It was in fact never considered a waste product of the body but rather as a distilled product selected from the blood and containing useful substances for the care of the body. It was referred to as the "gold of the blood" and "elixir of long life," indicating its therapeutic potential. This paper reports on the practice of urine therapy since its origin attributed to the Indian culture, and briefly reviews its use through the centuries and different cultures and traditions. Records from the Egyptians to Jews, Greeks, Romans and from the Middle Ages and the Renaissance testify to the practice of urine therapy--a practice that continues to be found in more recent times, from the 18th century to the present. Experiences with the practice of urine therapy have even been discussed and shared recently in 2 different conferences: in 1996 in India and in 1999 in Germany, where people from different countries shared and presented their own research on urine therapy.

    In 1543 in Basel, Johannes Oporinus published one of the most famous treatises in the history of anatomy, De humani corporis fabrica by Andreas Vesalius. The book was an immediate success all over Europe, especially in the Upper Rhine region. In Strasbourg, Walter Ryff (Gualterius Rivius) was responsible for an early copy; others followed, as for example Felix Platter in Basel in 1581. One of the novelties of all these books consisted in the fact that for the first time the human body was dissected into its smallest units. Anatomical elements such as the opened thorax, the vertebral column, the kidney sectionned, or the laryngeal cartilages apparently stimulated an artist of the late 16th century in the same geographical region: Wendel Dietterlin (c.1550-1599) who principally worked in Strasbourg and introduced these elements into his treatise on architecture as architectural ornaments. This seems to be the first instance of a transfer of motifs from human anatomy to architecture. From this time on, the transfer reappeared in some works until William Hogarth's era in the 18th century.

    In the poster presentation a series of historical and recent floods of the Maros river, with special emphasis on the flood events occurred on the lower sections, are presented. Similar to the Hungarian flood databases of the Middle-Danube and Lower-Tisza, the main sources of investigations are the institutional (legal-administrative) documentary evidence (e.g. Szeged and Makó town council protocols and related administrative documentation, Csanád County meeting protocols) mainly from the late 17th-early 18th century onwards. However, in case of the Maros river there is an increased importance of narrative sources, with special emphasis on the early modern period (16th-17th century): in this case the (mainly Transylvanian) narratives (chronicles, diaries, memoires etc.) written by aristocrats, other noblemen and town citizens have particular importance. In the presentation the frequency of detected flood events, from the mid-16th century onwards (with an outlook on sporadic medieval evidence), is provided; moreover, a 3-scaled magnitude classification and a seasonality analysis are also presented. Floods of the Maros river, especially those of the lower river sections, often cannot be understood and discussed without the floods of the (Lower-)Tisza; thus, a comparison of the two flood series are also a subject of discussion. Unlike the Lower-Tisza, the Maros is prone to winter and early spring ice jam floods: since the floods that belonged to this type (similar to those of the Middle-Danube at Budapest) were the most destructive among the flood events of the river, this flood type, and the greatest flood events (e.g. 1751-1752, 1784) are also presented in more detail.

    A standardized tree-ring width chronology of the Scots pine (Pinus sylvestris L.) along with different types of documentary evidence (e.g. annals, chronicles, diaries, private correspondence, records of public administration, early newspapers) have been used to reconstruct air temperature in Poland. The ground surface temperature (GST) history has been reconstructed based on the continuous temperature logs from 13 wells, using a new method developed recently by Harris and Chapman (1998; Journal of Geophysical Research 103: 7371-7383) which is compared with the functional space inversion (FSI) method applied to all available Polish temperature-depth profiles analysed before.Response function calculations conducted for trees growing in Poland (except in mountainous regions) reveal a statistically significant correlation between the annual ring widths of the Scots pine and the monthly mean air temperatures, particularly from February and March, but also from January and April. Therefore, it was only possible to reconstruct the mean January-April air temperature.The following periods featured a warm late winter/early spring: 1530-90, 1656-70 (the warmest period), 1820-50, 1910-40, and after 1985. On the other hand, a cold January-April occurred in the following periods: 1600-50, 1760-75, 1800-15, 1880-1900, and 1950-80.Reconstructions of thermal conditions using documentary evidence were carried out for winter (December-February) and summer (June-August) from 1501 to 1840 and, therefore, their results cannot be directly compared with reconstructions based on tree-ring widths. Winter temperatures in this period were colder than air temperature in the 20th century. On the other hand, historical summers were generally warmer than those occurring in the 20th century. Such situations dominated in the 16th and 17th centuries, as well as at the turn of the 18th and 19th centuries. Throughout almost the entire period from 1501 to 1840, the thermal continentality of the climate

    times at the spring, based on the speed of the water taken with a hydraulic reel specially dedicated for this type of survey. These data show that an increase in water level of just 60 cm, produces a flow rate ten times higher than that during low discharge. During the peak discharge at the spring the probe has recorded a rise in the water level of over 11 metres, between 18:00 and 21:00 on November 18th, 2013. Part of this increase, however, was due to the barrier function of the nearby Cedrino river, whose high water level has blocked the drainage of the water from the karst system. The water spring level curve shows a temporary lowering around noon, before the flood peak, probably due to the opening of the dam. On the basis of the comparison between the measured speed of water flow in the stages immediately preceding and succeeding the flood event and of the values of water level recorded by the multi-parametric probe, it has been possible to estimate the contribution of the karst spring to the peak discharge of the river in around 40 cubic metres per second, a value of two orders of magnitude greater than the average flow of the spring (around 200 L/s).

    Biogenic reefs built by oysters and other suspension feeders are vital components of estuarine ecosystems. By consuming phytoplankton, suspension feeders act to suppress accumulation of organic matter in the water column. Nutrient loading increases the rate of primary production, thereby causing eutrophication. As suspension feeders consume more organic matter from increasing abundance of phytoplankton, their rate of growth should also increase if they are food limited. We show here that the eastern oyster, Crassostrea virginica (Gmelin), from St. Mary's and Patuxent rivers, Chesapeake Bay, grew faster during anthropogenic eutrophication relative to C. virginica before eutrophication. Growth of shell height, shell thickness and adductor muscle increased after eutrophication began in the late 18th century. After 1860, growth decreased, perhaps reflecting the negative effects of hypoxia, harmful algal blooms, disease and fishing on oyster growth. These results are consistent with the view that an increasing supply of phytoplankton resulting from eutrophication enhanced growth of C. virginica between 1760 and 1860, before oyster reefs were degraded by destructive fishing practices between 1870 and 1930. Alternative factors, such as changes in water temperature, salinity, and fishing are less likely to be responsible for this pattern. These results have implications for restoration of oyster reefs in order to mitigate the effects of eutrophication in estuaries, as well as the paleoecological relationship between suspension feeders and paleoproductivity.

Clear cutting was responsible for the mediaeval first large scale expansion of drift sand landscapes. In such driftsand landscapes, the majority of the podzolic soils in coversand has been truncated by aeolian erosion. Only on scattered sheltered sites in the landscape, palaeopodzols were buried under mono or polycyclic driftsand deposits. They are now the valuable soil archives for palaeoecological research. During the 18th century, the population growth and regional economic activity stimulated the agricultural productivity. Farmers introduced the innovative 'deep stable' technique to increase the production of fertilizers. Farmers started sod digging, including the top of the Ah horizon of the humus forms. This consequently promoted heath degradation and sand drifting, resulting in the extension of driftsand landscapes. Deep stable economy and sod digging was responsible for the 18th century second large scale expansion of drift sand landscapes. During the 19th century, farmers tried to find alternative fertilizers and authorities initiated reforestation projects. The invention of chemical fertilizers at the end of the 19th century marked the end of the period of heath management and plaggic agriculture. The heath was no longer used for the harvesting of plaggic matter and new land management practices were introduced. Heath was reclaimed to new arable land or reforested with Scotch pine. Geomorphological features as inland dunes and plaggic covers survived in the landscape and are now included in the geological inheritance.

    Steele, John M.

    The last five centuries BC saw the development of several new forms of astrology in Babylonia. Key to these new astrological techniques was the invention of the zodiac in about 400 BC. These new forms of astrology include personal horoscopes, astral medicine, and the exploitation of geometrical relationships between the position of heavenly bodies. Several Late Babylonian astrological doctrines were later adopted within Greek astrology.

    Monsoonal-affected temperate glaciers in the eastern Nyainqêntanglha Range, southeastern Tibet, are highly sensitive to climate change. Knowledge about their late Holocene dynamics is still, however, widely lacking. The few studies on glacial chronology which are available for this region tend to mainly focus on dating results without sufficiently considering the geomorphological setting, often leading to misinterpretations in this complex high mountain environment. In this study, two selected glacier forelands are investigated using a multi-proxy approach encompassing detailed geomorphological mapping, dendrochronology, sedimentology, and optically stimulated luminescence as well as radiocarbon dating. The starting point was the creation of a consistent morphosequence which was validated by remote sensing of further glacier forelands from the wider region. Similarities and differences between the investigated settings were analyzed in detail to identify the relevant morphological and topoclimatic forcing mechanisms. We found evidence of climatic events affecting the whole region during the Little Ice Age, resulting in similar configurations and numbers of moraines. The geomorphological settings of the glacier forelands are, however, remarkably different, making investigations of the landform and sediment configuration an indispensable condition for their interpretation. Subsequently, constraints from different methods of relative and numerical dating were evaluated critically and included into a conceptual chronosequence if applicable. Our results suggest that the late Holocene maximum glacier advance comprised several successive advances from mid-17th to mid-18th century. None of our observations supports an earlier Neoglacial advance reaching further than the LIA maximum. After the LIA maximum, continued retreat that was only interrupted by short phases of stability followed, as evidenced by 2-3 recessional moraines in the investigated settings.
