    The sunspot and group numbers in the 18th Century relies heavily on the observations by J.C. Staudauch during 1749-1799 performed with a three-foot 'sky tube', likely affected by spherical and chromatc aberration. An observing network has been set up to make drawings of the spots on the solar disk using original telescopes from the 18th Century or reconstructed 'sky tubes' with the same defects as the instruments available to and affordable for amateurs of the period. We report the initial results of the effort, finding that the counts of groups and the sunspot numbers must be multipled by three to reproduce modern observations. This confirms the scale factors derived from recent revisions of the solar record.

  3. [Criminal madness in the 18th century].

    Barras, V

    1990-01-01

    Forensic psychiatry, as we know it, was established in the early 19th century. But already the "Ancien Régime" knew--with regard to mentally disturbed criminals--particular legal and medical considerations and practical arrangements. The author analyses the theoretical reasoning of some cases selected from the judicial archives of Geneva (mainly 18th c.). This enables him to establish the great lines of a "prehistory" of forensic-psychiatric expertise.

  4. [Counteraction against alcoholism in religious letters of 18th century].

    Rok, B

    1999-01-01

    The Polish historiography talks at length about the problem of alcoholism in Poland in the 18th century. Estimates were made about the scale and consumption of alcoholic beverages. Many records are available today, mainly in the form of diaries, which describe the extent of drunkenness at that time. Much information on drinking bouts comes from satires (this article quotes after an anonymous satire found in the Polish manuscripts of the 18th century). Apart from the literature, also preachers contributed to the present knowledge of alcohol consumption within that period. Drunkenness was often mentioned in sermons and varied types of religious guides. The 18th century priests deemed drunkenness as a heavy sin and fiercely counteracted the abuse of alcoholic beverages, by condemning people in a state of intoxication.

    2013-01-01

    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.

    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.

  19. Chapter 9: understanding the nervous system in the 18th century.

    PubMed

    Smith, Christopher U M

    2010-01-01

    The 18th century was an age of transition. The time-honored neuropsychology of classical and medieval times, mechanized in Descartes' hydraulic neurophysiology, was undermined by microscopical observations and careful physiological experimentation. Yet it was not until the very end of the century, when work on electric fish and amphibia began to suggest an acceptable successor to "animal spirit," that the old understanding of human neurophysiology began to fade. This chapter traces this slow retreat from the iatrophysics of the early part of the century, with its hollow nerves and animal spirits, through a number of stop-gap explanations involving mysterious subtle fluids or forces described variously as irritability, élan vital, vis viva, vis insita, the spirit of animation etc., or perhaps involving vibrations and vibratiuncles and mysterious magnetic effluvia, to the dawning electrophysiology of the end of the century and the beginning of the next. This developing understanding filtered slowly through to affect medical education, and the 18th century saw the development of strong medical schools at Leiden, Edinburgh, Paris, Bologna and London. Associated with these developments there was a great increase, as a well-known physician looking back at the beginning of the following century noted, in a class of diseases that had little concerned physicians in the preceding century - "nervous disorders."

    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.

  1. From Flamsteed to Piazzi and Lalande: new standards in 18th century astrometry

    NASA Astrophysics Data System (ADS)

    Lequeux, James

    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

    The herbarium of the 19th-century Neapolitan botanists Vincenzo and Francesco Briganti was acquired by Orazio Comes in 1892 for the Royal Higher School of Agriculture in Naples. Based on a study of the handwriting on their labels, Comes concluded that some of the dried specimens were the sole remains of the herbarium of Domenico Cirillo, the distinguished 18th-century Neapolitan botanist, entomologist and physician. The current arrangement of the specimens not uniform and it is clear that they underwent extensive handling and rearrangement Some of the exsiccata are preserved in two packets, fixed on sheets bearing a printed label that reads "Herbarium D. Cyrilli". In an additional label Gaetano Nicodemi's handwriting and not Cirillo's as stated by Comes was identified. Other specimens, many of them mounted in a different manner from those in the first group, are arranged in another three packets. Certain characteristics of the herbarium may be explained by the vicissitudes of its history, including a hasty salvage operation. A study of the collection was conducted, including an analysis of the handwritten labels and notes, leading to conclusions that shed light on the significance of the Cirillo collection within the historical and scientific context of 18th-century Naples.

    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

    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.

    2014-03-01

    Consultations by post make up together a significant part of the medical literature, especially between the 16(th) and 18(th) centuries and bring irreplaceable testimonies on how physicians could follow up their patients from far away, in relation with local practitioners who were at their patients' bedside or who could visit them on a regular basis. These testimonies are of a scientific nature since they show how illustrious physicians diagnosed, predicted and prescribed, such as Fernel, Chirac and later on Barthez and Tissot, or less famous practitioners such as Le Thieullier, for instance. They are of a literary nature since every physician has his own writing style, and the lay out of their letters often respects codes. They are of an anthropological nature in the sense that a conception of man, ill, with his character, his own life, is rendered under the form of narratives.

  6. Early 18th century cosmic ray flux inferred from 44Ti in Agen meteorite

    2016-10-01

    We report the measurement of radioactivity of cosmogenic 44Ti in Agen meteorite, a H5 chondrite that fell in 1814. The 44Ti activity in meteorites is related to centennial-scale changes in cosmic ray intensity caused by heliospheric magnetic field modulation in the interplanetary space between heliocentric distances of 1 and 3 AU. The measured low 44Ti activity in Agen suggests a strong modulation of galactic cosmic rays at the turn of the 18th century, resulting in a low cosmic ray flux and is consistent with the linearly decreasing trend of GCR flux, modulated by the Gleissberg solar cycle during the past 250 years, as previously suggested by us.

    The views on the life in the early modern period (the 17th and 18th centuries) with their socio-cultural backgrounds and their meanings at that time were discussed in this paper. 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.

    The following calendar systems, introduced in Europe from 18^{th} to 20^{th} century, which were in use for a shorter or longer period by a larger or smaller community, were reviewed and discussed: The French Revolutionary Calendar, the Theosebic calendar invented by Theophilos Kairis, the Revolutionary Calendar of the Soviet Union (or 'Bolshevik calendar'), the Fascist calendar in Italy and the calendar of the Metaxas dictatorship in Greece before World War II. Also the unique of them, which is still in use, the New Rectified Julian calendar of the Orthodox Church, adopted according to proposition of Milutin Milanković on the Congress of Orthodox Churches in 1923 in Constantinople, is presented and discussed. At the end, difficulties to introduce a new calendar are discussed as well.

    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.

  10. Head injuries in the 18th century: the management of the damaged brain.

    PubMed

    Ganz, Jeremy C

    2013-07-01

    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.

  11. 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.

    This historical paper deals with medical dissertations from the second half of the 18th century which deal with stomatology. 30 of the 100 consulted dissertations were translated from latin with great differences in scientific content and style, because they dated from the 16th to the 18th century. The views of normal anatomy and physiology of that time are described. Strange views were held on the embryological development. Apart from toothache, dentitio difficilis in children, aphtous stomatitis, cleft palates and the respective therapies were described. The scientific content of those dissertations was way backward when compared to contemporary text book literature.

    2013-04-01

    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.

    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.

    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.

  18. A comparison of large 18th-century floods on Danube: Vienna - Bratislava - Budapest

    The documentation of historic floods can help in better understanding of factors that might cause and contribute to large and extreme flood events. In particular, the analysis of historic floods provides information about flood seasonality, its changes and anthropogenic impacts on river flood regime which in some cases strongly influenced flood behaviour. The main objective of the present contribution is to document large and medium size flood events on Danube in Vienna, Bratislava and Budapest in the 18th century. In the present study, based on contemporary documentary evidence, for each of the three towns a five-scaled flood index series is developed to describe the magnitude and intensity of flood events. According to this classification, the 100-year flood event was characterised by the index value 5, while great destructive floods - depending on their extension, destructivity and further impacts - received the values 4 and 3, respectively. Less significant but still harmful flood events were classified as No. 2, and floods without further specification remained in the lowest category (No. 1). Beside classification issues, seasonality and flood frequency differences between the three towns are as well discussed. The results indicate that a greater number of flood events took place in the last decades of the century, but only a few flood events of the same magnitude are documented simultaneously in all three towns. And whereas in 1775 no winter flood event was reported in Vienna, an important ice jam flood was documented in Bratislava, and a catastrophic ice jam flood event, greatest of the century, occurred in Budapest. In 1787 autumn the greatest flood event of the century occurred in Vienna, while hardly any flood waves were observed at Budapest. While in Vienna, summer (and partly autumn) floods had great importance, in Budapest a large number of ice jam floods were documented. In some cases the differences are likely caused by different hydrometeorological

    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.

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

    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

    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.

    In less than a century, French surgery changed completely by ceasing to be an uncertain technique practised by routine practitioners and becoming a scientific discipline. This transformation involves the 4 following aspects: 1. The surgeon becomes an anatomist, a scientist, a clinician and a pathologist. 2. New structures and new teaching methods are adopted. 3. The separation between medicine and surgery progressively decreases; if not structurally at least in fact, surgery becomes associated to medicine. 4. Surgery takes a prominent place in the private life of the French. In the light of these facts, it could be said that surgery has developed medicine to a point where it raises new hopes for the scientific world and gains the support and esteem of the public at the end of the XVIIIth century.

    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.

    Mummified remains have been successfully studied radiologically since the end of the 19th century, giving rise to a specific field of research-paleoradiology. In this paper, we present the results of the first radiological investigation of a collection of Sicilian mummies found in a subterranean chamber beneath the Capuchin Church of Savoca. The chamber contains a number of preserved bodies, either held in special niches in the walls or interred within coffins. A recent detailed radiological examination of these mummies allowed the authors to determine information relating to the funerary treatment and some of the pathological alterations witnessed in the remains. Specifically, evidence of gout and DISH was identified, along with frequent degenerative joint disease, suggestive of rich dietary habits and a longer life expectancy. These findings were interpreted in the light of historical information and the social status of the subjects concerned.

    "The very high quality of a set of marriage records for Paris during the 1860s made it possible to apply indirect methods to estimate adult mortality differentials by certain geographical and social criteria of the 19th century. The largest differences between groups were observed to be social, geographical origin apparently having little impact.... It is interesting that social differences in adult mortality are similar in magnitude to those observed today. Perhaps the principal factor of differentiation is then the level of child mortality.... It is by no means necessary to have a set of data as complete as ours. The indirect methods we have used proved largely adequate for estimating mortality differentials."

    2001-01-01

    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. PMID:11762404

    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.

    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.

  1. 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.

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

    2011-01-01

    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

    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.

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

    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”.

    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 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.

    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.

  15. Captain Cook's beer: the antiscorbutic use of malt and beer in late 18th century sea voyages.

    2003-01-01

    The custom of allowing British seamen the regular use of fermented liquor is an old one. Ale was a standard article of the sea ration as early as the fourteenth century. By the late eighteenth century, beer was considered to be at once a food (a staple beverage and essential part of the sea diet), a luxury (helping to ameliorate the hardship and irregularity of sea life) and a medicine (conducive to health at sea). In particular, beer and its precursors, wort and malt, were administered with the aim of preventing and curing scurvy. This paper examines the use of malt and beer during late eighteenth century British sea voyages, particularly their use as antiscorbutic agents, focusing on James Cook's three voyages during the period 1768-1780. Cook administered sweet wort (an infusion of malt), beer (prepared from an experimental, concentrated malt extract), and spruce beer (prepared mainly from molasses), among many other items, in his attempts to prevent and to cure scurvy. Despite the inconclusive nature of his own experiments, he reported favourably after his second voyage (1772-1775) on the use of wort as an antiscorbutic sea medicine (for which purpose it is now known to be useless). Cook thereby lent credibility to erroneous medical theories about scurvy, helping to perpetuate the use of ineffective treatments and to delay the discovery of a cure for the disorder. PMID:12810402

    Several Finish wallpapers from the 18th and 19th century were analysed by using Raman spectroscopy assisted with EDXRF instrumentation, in an attempt of determine the pigments used in their manufacture process as well as of trying to date some of the samples through pigment composition. All pigments present in samples were determined and surprisingly the unusual and strange iron (III) chromate yellow pigment was found. Besides, unusual mixtures were found to obtain fashionable colours, especially in blue and green areas, where more than one blue pigments were mixed with green and yellow pigments. Blue verditer, ultramarine blue, Prussian blue, chrome yellow, calcite, lead white, red and yellow iron oxide, gypsum and carbon black were identified. The presence of the risky and poisonous emerald green must be highlighted. The results were compared with those found in other wallpapers from Spain and France.

    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.

    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. PMID:19935970

    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 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. PMID:20063670

    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.

    Fertility responded negatively to grain insufficiency (proxied by grain price increases), and mortality responded positively in Croatia-Slavonia-Srem in the 18th and 19th centuries, as in most of Europe. Shifts in the intensity and timing of these responses occurred over time as social and economic structures changed. Shifts in the elasticity of fertility with respect to grain supply inversely mimic and lag changes in the elasticity of mortality. Both appear to be induced by increasing land shortage, the collapse of feudalism, and differences in the patterns of adjustment to post-feudal conditions among former civil and military serfs. Generally, responses are stronger for civil and former civil serfs, who may have been in less favorable economic circumstances than the military. Fertility responses in the year of a price shock come to dominate those in the year following, suggesting a shift from contraception to abortion as economic and social conditions apparently worsened and strategies of control intensified. Analysis of monthly responses supports the conjecture based on the annual responses. The shift to the preventive check and strength of the preventive check in the same year as the price shock is unusual in Europe and beyond. Analysis is based on 25 parishes and employs lagged annual and monthly time series analysis with corrections for autocorrelation, in combination with ethnographic and historical data.

    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.

    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.

    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.

    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

    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.

    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 Supreme Board of Health was the first Spanish health institution that took responsibility for health throughout the entire territory of the Crown. Established in 1720 at the behest of Felipe V, the Board was endowed of wide prerogatives from the political and administrative point of view, and was characterized by a rational, centralist stance. In practice, however, its function was limited in essence to the preservation of the Kingdom and the protection of the people's health against catastrophic diseases. It adopted measures of a defensive nature in the face of the various epidemics that occurred within the outside of Spain during the eighteenth century.

    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.

    Eighteenth-century gardens have traditionally been viewed as spaces designed for leisure, and as representations of political status, power and taste. In contrast, this paper will explore the concept that gardens in this period could be seen as dynamic spaces where scientific experiment and medical practice could occur. Two examples have been explored in the pilot study which has led to this paper — the designed landscapes associated with John Hunter’s Earl’s Court residence, in London, and the garden at Edward Jenner’s house in Berkeley, Gloucestershire. Garden history methodologies have been implemented in order to consider the extent to which these domestic gardens can be viewed as experimental spaces. PMID:26052165

    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.

    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.

    The most critical steps during the conservation-restoration treatment applied in Moroccan libraries are the deacidification using immersion in a saturated aqueous calcium hydroxide (Ca(OH)2) solution and the consolidation of degraded manuscripts using Japanese paper. The present study aims to assess the efficiency of this restoration method using a multi-analytical approach. For this purpose, three ancient Arabic Moroccan manuscript papers dating back to the 16th, 17th, and 18th centuries were investigated to characterize the paper support and make a comparative study between pre-restoration and post-restoration states. Three structural and molecular characterization techniques including solid-state nuclear magnetic resonance spectroscopy on (13)C with cross-polarization and magic-angle spinning nuclear magnetic resonance ((13)C CP-MAS NMR), attenuated total reflectance Fourier transform infrared spectroscopy (ATR FT-IR), and X-ray diffraction (XRD) were used to elucidate the cellulose main features, to identify the inorganic composition of the papers, and to study the crystallinity of the samples. Inductively coupled plasma atomic emission spectrometry (ICP-AES) allowed us to obtain a qualitative and quantitative characterization of the mineral fillers used in the manufacturing of the papers. Scanning electron microscopy coupled to energy dispersive spectrometry (SEM-EDS) ascertained the state of conservation of the different papers and helped us to study the elemental composition of the samples. After restoration, it was shown that the deacidification improved the stability of papers by providing an important alkaline buffer, as demonstrated using FT-IR and energy dispersive spectrometry (EDS) results. However, XRD and ICP-AES did not confirm the pertinence of the treatment for all samples because of the unequal distribution of Ca on the paper surface during the restoration. The consolidation process was studied using SEM analysis; its effectiveness in restoring

    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.

    interannual and D/I coral δ18O variability from equatorial sites in the Pacific (e.g. Maiana). Collectively, our results from the SPCZ region reflect the validity of the coral δ18O composite to track regional climatic variability at both interannual and decadal/interdecadal timescales. From the late 18th century to the late 19th century the D/I band dominates the Fiji composite while the ENSO-band amplitude is relatively small. Starting around 1885, this tendency reverses and we observed a drastic decrease in the D/I signal amplitude, with its variance reduced by more than 50%, while the ENSO-band signal increases progressively in amplitude toward the present, reaching unprecedented values during the mid-20th century. This switch around 1885 A.D. is unique over the last 250 years and may correspond to a reorganization of Pacific-wide climate.

    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.

    With the development of our present day domesticated animals in America (during the 16th and 17th centuries), it was not long before animal diseases became troublesome and destructive (especially during the latter half of the 18th century). Though veterinary medicine became rather firmly established in many European countries (including England) during the latter half of the 18th century, veterinary medicine was relatively nonexistent in America, with only self-styled animal doctors and farriers (with their empirical and often destructive remedies).

    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. PMID:16086663

  17. 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.

    In nineteenth-century America, there was no such person as a "professional scientist". There were professionals and there were scientists, but they were very different. Professionals were men of science who engaged in commercial relations with private enterprises and took fees for their services. Scientists were men of science who rejected such commercial work and feared the corrupting influences of cash and capitalism. Professionals portrayed themselves as active and useful members of an entrepreneurial polity, while scientists styled themselves as crusading reformers, promoters of a purer science and a more research-oriented university. It was this new ideology, embodied in these new institutions, that spurred these reformers to adopt a special name for themselves--"scientists". One object of this essay, then, is to explain the peculiar Gilded Age, American origins of that ubiquitous term. A larger goal is to explore the different social roles of the professional and the scientist. By attending to the particular vocabulary employed at the time, this essay tries to make clear why a "professional scientist" would have been a contradiction in terms for both the professional and the scientist in nineteenth-century America.

  1. Mustaches and masculine codes in early twentieth-century America.

    Oldstone-Moore, Christopher

    2011-01-01

    The purpose of this article is to deepen our understanding of twentieth-century masculinity by considering the social function of facial hair. The management of facial hair has always been a medium of gendered body language, and as such has elicited a nearly continuous private and public conversation about manliness. Careful attention to this conversation, and to trends in facial hairstyles, illuminates a distinct and consistent pattern of thought about masculinity in early twentieth-century America. The preeminent form of facial hair - mustaches - was used to distinguish between two elemental masculine types: sociable and autonomous. A man was neither wholly one nor the other, but the presence and size of a mustache - or its absence - served to move a man one way or another along the continuum that stretched from one extreme to the other. According to the twentieth-century gender code, a clean-shaven man's virtue was his commitment to his male peers and to local, national or corporate institutions. The mustached man, by contrast, was much more his own man: a patriarch, authority figure or free agent who was able to play by his own rules. Men and women alike read these signals in their evaluation of men. PMID:22164885

    Tree-ring data suggest that the 8th and 16th century megadroughts may have been the most severe and sustained droughts to impact North America in the past 1500 years. The 16th century megadrought may have persisted for up to 40 years, and extended from the tropics to the boreal forest and from the Pacific to Atlantic coasts. Evidence for the 8th century drought is sparse, but tree-ring and lake sediment data indicate that this drought extended from the northern Great Plains, across the southwestern United States, and into central Mexico and the Yucatan peninsula. Tree-ring data from Colorado and New Mexico document severe drought from A.D. 735-765, and may provide accurate and precise dating for the onset of the epic droughts reconstructed during the late first millennium A.D. with sedimentary data from Elk Lake, Minnesota; Moon Lake, South Dakota; La Piscina de Yuriria, Guanajuato; and Lake Chichancanab, Yucatan. If these chronological refinements are correct, then the sedimentary records suggest much greater persistence to the 8th century megadrought than indicated by the very high resolution tree-ring data, and a strong second pulse of prolonged drought late in the first millennium. Analyses of instrumental precipitation and drought indices during the 20th century, along with tree-ring reconstructions of climate in Mexico and the Southwest, indicate that annual and decadal droughts can both simultaneously impact the entire region from New Mexico and Texas down into central Mexico. The intensity and large-scale impact of drought across this region seem to be greatest when La Nina conditions and the low phase of the North Pacific oscillation prevail. The tree-ring dated 8th century megadrought occurred near the decline of the Classic Period civilizations at Teotihuacan in central Mexico and in the Mayan region of the Yucatan. The 8th century megadrought may have interacted with anthropogenic environmental degradation, epidemic disease, and social upheaval to

  4. 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."

    The history of music therapy in the United States has not been thoroughly investigated and documented. The few sources containing information on the historical uses of music in medicine concentrate primarily on 20th century practices, while virtually omitting 19th century contributions to the field. The purpose of this study was to analyze elected music therapy literature that appeared in 19th century medical journals and dissertations. The articles found in these publications indicated interest during this time in advocating the use of music to provide the patient an alternate, more holistic approach to treatment. The dissemination of music therapy ideas occurred almost exclusively through these publications, which unfortunately resulted in very limited proliferation of the topic because of the nature of the audience (i.e.,primarily physicians). Nine articles were analyzed; the study was based on primary evidence located in medical journals and dissertations written between 1804 and 1899. The sources were located in a variety of bibliographies found in books, journals, dissertations, and theses.

    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

    At the turn of the century, from 2000 to 2004, western North America (25°-50°N, 100°-125°W) experienced a severe drought with far reaching consequences for the terrestrial biosphere. We quantified the drought's water and carbon cycle implications using upscaled flux tower data, observed and simulated fluxes from the NACP Site Synthesis, remote sensing products, weather reanalysis, crop yield, and river discharge. During the turn of the century drought we found a widespread drydown of the terrestrial biosphere, large decreases in river discharge and greenness, and a ~10% loss in cropland productivity. At the footprint scale carbon uptake declined with an anomalous carbon source of 0.11 Pg C/yr integrated over the full domain. Flux towers also recorded a clear signal of reduced latent and increased sensible heat fluxes, apart from grasslands. Dendrochronological reconstructions of drought extent, duration, and severity, based on the Palmer Drought Severity Index drought metric, indicated that the turn of the century drought was unprecedented since 1200 CE. Predicted changes in precipitation and drought, based on the CMIP3 multi-model mean, could permanently disable the weak sink (NEE = -0.19 Pg C/yr) in western North America by the midpoint of the 21st Century. Projections indicate the turn-of-the-century drought will be wet compared to the latter half of the 21st Century.

    A key feature of anticipated 21st century droughts in Southwest North America is the concurrence of elevated temperatures and increased aridity. Instrumental records and paleoclimatic evidence for past prolonged drought in the Southwest that coincide with elevated temperatures can be assessed to provide insights on temperature-drought relations and to develop worst-case scenarios for the future. In particular, during the medieval period, ∼AD 900–1300, the Northern Hemisphere experienced temperatures warmer than all but the most recent decades. Paleoclimatic and model data indicate increased temperatures in western North America of approximately 1 °C over the long-term mean. This was a period of extensive and persistent aridity over western North America. Paleoclimatic evidence suggests drought in the mid-12th century far exceeded the severity, duration, and extent of subsequent droughts. The driest decade of this drought was anomalously warm, though not as warm as the late 20th and early 21st centuries. The convergence of prolonged warming and arid conditions suggests the mid-12th century may serve as a conservative analogue for severe droughts that might occur in the future. The severity, extent, and persistence of the 12th century drought that occurred under natural climate variability, have important implications for water resource management. The causes of past and future drought will not be identical but warm droughts, inferred from paleoclimatic records, demonstrate the plausibility of extensive, severe droughts, provide a long-term perspective on the ongoing drought conditions in the Southwest, and suggest the need for regional sustainability planning for the future.

    The Spanish colonization of the Americas expanded since the beginning of the XVIth century until the beginning of the XIXth century, when most of the colonies became independent. During this period, a large amount of documentary information was produced, due to the fact that the Spanish Empire was highly centralized and bureaucracy was one of its core elements. Most of these documents are well preserved either in local archives in the Americas or in the Archivo General de Indias in Sevilla, which keeps thousands of bundles relative to any relevant aspect of the ordinary life of the colonies. Different projects are now searching climatic information in this archive with very encouraging results. During the XIXth century Spain kept two colonies in the Americas: Cuba and Puerto Rico, which became independent in 1898. This has allowed that a lot of information survived in Spanish Archives for this period. After a preliminary inspection of different Spanish Archives: Archivo General de Indias, Archivo del Museo Naval and Archivo Histórico Nacional (General Archive of Indies, Archive of the Naval Museum and National Historic Archive), it has been possible to identify two main areas of climatic interest: 1) information from ship logbooks connecting Spain with Cuba and Puerto Rico and 2) reports about hurricanes. The information contained in the ship logbooks is very rich and could help to better characterize elements of the large-scale circulation in the Atlantic; the reports on hurricanes can be very detailed and were elaborated by very skilled personnel. The presentation will provide different examples of the potential of these sources and describe different Spanish projects involved in the abstraction of this type of data.

  2. Public health and working children in twentieth-century America: an historical overview.

    Throughout this century, concern for the health of America's youth has been a driving force in the long fight to regulate child labor. The prevalence of children in dangerous trades like mining and mill work at the start of the century was a major factor behind the creation of a national child labor reform movement. Not until the Fair Labor Standards Act of 1938, however, were reformers able to secure universal age, hour and health standards for working youngsters. In the decades following World War 2, child labor dramatically declined in the United States. But new waves of immigration in the 1980s, along with increased participation of high school students in the service sector, have contributed to a resurgence in juvenile employment and focused renewed attention on the health risks faced by minors in the workplace.

  3. Three Centuries of Synchronous Forest Defoliator Outbreaks in Western North America

    Insect outbreaks often occur synchronously across large spatial scales, but the long-term temporal stability of the phenomenon and the mechanisms behind it are not well understood. In this study, I use a widespread lepidopteran defoliator native to western North America—the western spruce budworm—as a case study to explore patterns of and potential causes for synchronous population fluctuations. Analyses of synchrony are typically severely limited by the short historical records available for many species. To overcome this limitation, I compiled multi-century dendrochronological reconstructions of western spruce budworm outbreaks from across much of the species’ range. This allowed me to analyze synchrony at a sub-continental spatial scale over the last three centuries. I found statistically significant synchrony among regional outbreak records up to 2,000 km apart and identified numerous outbreak periods that occurred synchronously across much of the species’ range. I quantified spatial and temporal associations between climate and synchronous outbreak periods using paleoclimate reconstructions. The spatial patterns of outbreak histories and climate records were remarkably similar, with higher similarity in outbreak histories apparent between regions with more similar climate conditions. Synchronous outbreaks typically occurred during periods of average or above average moisture availability preceded by periods of low moisture availability. My results suggest that climatic variability has played a key role in synchronizing western spruce budworm population fluctuations in disjunct forests across western North America for at least the last three centuries. Widespread synchrony appears to be a natural part of this species’ population dynamics, though synchronous outbreaks have occurred more frequently during the 20th century than during prior centuries. This study uses a novel combination of statistical methods and dendrochronological data to provide

    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.

  6. Feeding better food habits in mid-20th-century America.

    Public health nursing work has always involved education about nutrition and food habits. Nurses serve as interpreters of scientific and medical knowledge and as agents of behavioral change among the individuals and groups for whom they provide care. For public health nurses in mid-20th-century America, this meant direct involvement in many aspects of family life at home. Meal preparation and the eating patterns of family members were two areas into which most public health nurses had access. This brief history provides an introduction to some of the issues confronting American public health nurses at mid-century. Examining the content of articles related to nutrition in families around mid-century yields evidence about the role of the nurse, the state of the art in nutritional knowledge, and opinions and prejudices related to eating habits prevalent at the time. These glimpses into concerns expressed in the original Public Health Nursing journal may enhance understanding of the role of public health nurses in preventing diet-related disorders and form the basis for additional historical research.

    We present a review of the biological systematic research in Latin America during the twentieth century, applying a bibliometric analysis to the information contained in international databases with the largest number of biological records: Biosis (since 1969), CAB (since 1910) and Science Citation Index (since 1900), to recognize certain patterns and trends regarding the document production. We obtained 19079 documents and 1387 journals for Biosis, 14326 and 2537 for CAB, 3257 and 1636 for SCI. Of the documents, 54.6% related to new species, 15.3% dealt with morphology, 14.9% keys, 12.5% descriptions, 10.6% cases of synonymies, 6% new genera, 4.9% new geographical records, 23.6% geographical distribution, 4.2% redescriptions, and 3.6% with new nomenclatural combinations. The regions mentioned were South America with 11.9%, Central America with 4% and America (all) with 2.56%. Nineteen Latin American countries appear, whereas outside this region we found the United States of America with 12.6% of representation and Canada with 3%. Animals (65.6%) were the most studied taxa, which was 1.7 times higher than what was published for plants (37%), 11 times higher than fungi (6%) and nearly 30 times higher than microorganisms (2.3%). Out of the 155 journals that produced 66% of the papers, 76.5% were better represented in Biosis, 21.4% in CAB and 2% in SCI. Twenty-nine journals published 33% of the articles, the maximum number of records obtained was 69% for Biosis, CAB 24% and 6.9% for SCI, three (10.3%) are in biology, 11 (37.9%) in botany, 13 (44.8%) zoology, and two (6.9%) paleontology; eight of these journals (27.5%) were published in Latin America and twenty were indexed in the Science Citation Index. In the last two years more journals of the region that publish on taxonomy have been indexed, but their impact factor is still low. However, the impact factor of a number of Latin American journals that published biodiversity increased with time. Countries that are

    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

    Rapid and broad-scale forest mortality associated with recent droughts, rising temperature, and insect outbreaks has been observed over western North America (NA). Climate models project additional future warming and increasing drought and water stress for this region. To assess future potential changes in vegetation distributions in western NA, the Community Earth System Model (CESM) coupled with its Dynamic Global Vegetation Model (DGVM) was used under the future A2 emissions scenario. To better span uncertainties in future climate, eight sea surface temperature (SST) projections provided by phase 3 of the Coupled Model Intercomparison Project (CMIP3) were employed as boundary conditions. There is a broad consensus among the simulations, despite differences in the simulated climate trajectories across the ensemble, that about half of the needleleaf evergreen tree coverage (from 24% to 11%) will disappear, coincident with a 14% (from 11% to 25%) increase in shrubs and grasses by the end of the twenty-first century in western NA, with most of the change occurring over the latter half of the twenty-first century. The net impact is a ~6 GtC or about 50% decrease in projected ecosystem carbon storage in this region. The findings suggest a potential for a widespread shift from tree-dominated landscapes to shrub and grass-dominated landscapes in western NA because of future warming and consequent increases in water deficits. These results highlight the need for improved process-based understanding of vegetation dynamics, particularly including mortality and the subsequent incorporation of these mechanisms into earth system models to better quantify the vulnerability of western NA forests under climate change.

  12. The Teaching of Astronomy in Jesuit Colleges in the 18th century

    Casanovas, J.

    On the occasion of the 250th anniversary of the foundation of the astronomical observatory at the college and seminary of Nagyszombat in 1755, it may be of interest to say something about the colleges of the Society of Jesus. The presence of the Jesuits there was brief, only two decades, as under the pressure of various external forces, the Jesuit Order was suppressed by Pope Clement XIV with the bull Dominus ac Redemptor on 23 July 1773. All the colleges that the Society had been running successfully all over the world either were closed, taken over by the governments, or given to the local bishops. Shortly after the Jesuits left the college of Nagyszombat, the king transferred it to Buda, where it gave rise to modern institutions of higher education derived. When Pope Pius VII returned to Rome after the Napoleonic wars, one of the first things he did was to reestablish the Society of Jesus in 1814. Old Jesuits, survivors of so many disgraces, joined younger Jesuits from Russia and Poland where in fact the order had never been suppressed. The most important of the Jesuit colleges, the Collegium Romanum in Rome, was given back to the Society of Jesus in 1823. Many other colleges were lost forever, but new ones were founded to continue the Society's previous successful activity.

    John Hyacinth de Magellan, whose Portuguese name was João Hyacintho de Magalhaens, though not a doctor nevertheless had many contacts with doctors and showed a genuine interest in disseminating medical news to his many friends and correspondents in Europe. The abundant and less formal correspondence with his friend Ribeiro Sanches forms the greater part of the work but in letters to other correspondents, including Trudaine de Montigny, Condorcet, Volta, J A Euler, Fabroni and Johann III Bernoulli, we find comments on medical subjects. The Sanches letters are particularly interesting because they are private, friend-to-friend letters that convey spontaneous and sincere thoughts and feelings.

    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.

    Author outlines the history of making and of development of public health during the period of enlightenment in Central Europe, with special regards on the Habsurg Empire, on Poland and on Russia. This development--including the foundation or reforms of medical education--was highly influenced by the ideas of the enlightened absolutism and by other international trends of the age as well. The detailed analysis of the factors shaping the history of public health in the three rather different countries shows an interesing parallelism regarding main issues. While re-organization of public health in all these countries was initiated and directed by the government and shaped according to western models, it was strongly influenced by local possibilities, culture and history.

    Following the First Partition in 1772, Poland lost the salt mines in Wieliczka, Bochnia and in the territory of Ruthenia to Austria. This was a serious blow to the economy, because since then, it became necessary to import salt, which was primarily taken advantage of by the Royal Prussian Maritime Trading Company (Pruska Kompania Morska) importing it from Austria. King Stanislaw August Poniatowski tried to initiate the exploration and exploitation of salt in the areas where it could be profitable. To this end, he ordered the exploration to Filip Carosi and Stanislaw Okraszewski, among other. The salt-works of the Castellan of Leukow, Jacek Jezierski in the town of Solca, in the Lqczyckie Region, active since 1780, was a private investment. Leopold von Beust's Kompania akcyjna obtained salt from a brine near the town of Busko, and Kompania z Osob Krajowych--from a brine in the town of Raczki nad Pilica. In 1782, the King appointed The Ore Commission (Komisja Kruszcowa), consisted of twelve commissioners, in order to conduct the exploration for minerals, including salt, their extraction and further administration. The Crown Treasury Commission (Komisja Skarbu Koronnego), a magistracy dealing with, among others, the economy of the country in a broad sense, was also involved in the exploration and exploatation of salt. At its command, in the summer of 1788, Tadeusz Czacki made a tour of the Kielce region in search of traces of salt. In view of the important events of the Four-Year Sejm (Sejm Czteroletni) and the subsequent loss of independence, the subject of salt exploration had to be abandoned.

    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.

    To give back dreaming to reason, to remove from it "that which is marvellous, supernatural and often terrible for the common man who studies it seriously", that is the intention of Jérôme Richard and Samuel Formey, who were both contemporaries of the philosophers of the Age of the Enlightenment. Relying on the medical theories of the time as well as on the explanatory models of physiology and psychology, they try to demonstrate "the true cause of dreaming" and the natural character of the oneiric phenomenon. The transmission of sensations, the working of memory and the association of ideas, the nature and power of imagination, the predetermined or random character of dreams constitute the framework of the questions from which the explanation of "all this apparent confusion" is developed.

    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.

    "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.

  3. [Reform of public health in Central Europe during the 18th century].

    2010-01-01

    Author outlines the history of making and of development of public health during the period of enlightenment in Central Europe, with special regards on the Habsurg Empire, on Poland and on Russia. This development--including the foundation or reforms of medical education--was highly influenced by the ideas of the enlightened absolutism and by other international trends of the age as well. The detailed analysis of the factors shaping the history of public health in the three rather different countries shows an interesing parallelism regarding main issues. While re-organization of public health in all these countries was initiated and directed by the government and shaped according to western models, it was strongly influenced by local possibilities, culture and history.

    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. PMID:27371361

    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. PMID:21208107

    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.

    Following the First Partition in 1772, Poland lost the salt mines in Wieliczka, Bochnia and in the territory of Ruthenia to Austria. This was a serious blow to the economy, because since then, it became necessary to import salt, which was primarily taken advantage of by the Royal Prussian Maritime Trading Company (Pruska Kompania Morska) importing it from Austria. King Stanislaw August Poniatowski tried to initiate the exploration and exploitation of salt in the areas where it could be profitable. To this end, he ordered the exploration to Filip Carosi and Stanislaw Okraszewski, among other. The salt-works of the Castellan of Leukow, Jacek Jezierski in the town of Solca, in the Lqczyckie Region, active since 1780, was a private investment. Leopold von Beust's Kompania akcyjna obtained salt from a brine near the town of Busko, and Kompania z Osob Krajowych--from a brine in the town of Raczki nad Pilica. In 1782, the King appointed The Ore Commission (Komisja Kruszcowa), consisted of twelve commissioners, in order to conduct the exploration for minerals, including salt, their extraction and further administration. The Crown Treasury Commission (Komisja Skarbu Koronnego), a magistracy dealing with, among others, the economy of the country in a broad sense, was also involved in the exploration and exploatation of salt. At its command, in the summer of 1788, Tadeusz Czacki made a tour of the Kielce region in search of traces of salt. In view of the important events of the Four-Year Sejm (Sejm Czteroletni) and the subsequent loss of independence, the subject of salt exploration had to be abandoned. PMID:25675732

    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.

    The Royal Council of Extremadura was established by Carlos IV on 30 May 1790. Within a few months, its officials undertook a visit of the whole territory. They drew up a questionnaire with 57 items that allowed them to collect specific information of interest to the court. Through the information gathered from the responses of the different communities, we have studied the distribution of the doctors and surgeons practising there. This analysis allowed us to confirm the many different health and health care conditions in the region, and the determining demographic, social and economic factors that were, in the final instance, decisive for the presence of these professionals.

    Today, the study of human anatomy utilizing the ultimate study guide, the cadaver, is relatively safe. In the past, however, human dissection was dangerous. Prior to the germ theory, antibiotics, and the use of gloves, cadavers were often life threatening to dissectors including both the teacher and the student. Medical students who graduated in the United States before 1880 were unlikely to practice antisepsis in the dissecting room. In the present article, we review human cadaveric dissection in Europe and the United States primarily from the 1700s to the early 1900s in regard to its potential for transmission of infection to the dissector. A brief account of the infectious hazards of human cadavers in general and those of cadavers used for dissection in particular is given.

    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. Uncertainties in the projected changes in precipitation due to different warming scenarios are non-negligible. Differences in summer precipitation changes between WRF and CCSM4 are significant over most of the United States.

  16. Between the national and the universal: natural history networks in Latin America in the nineteenth and twentieth centuries.

    PubMed

    Duarte, Regina Horta

    2013-12-01

    This essay examines contemporary Latin American historical writing about natural history from the nineteenth through the twentieth centuries. Natural history is a "network science," woven out of connections and communications between diverse people and centers of scholarship, all against a backdrop of complex political and economic changes. Latin American naturalists navigated a tension between promoting national science and participating in "universal" science. These tensions between the national and the universal have also been reflected in historical writing on Latin America. Since the 1980s, narratives that recognize Latin Americans' active role have become more notable within the renewal of the history of Latin American science. However, the nationalist slant of these approaches has kept Latin American historiography on the margins. The networked nature of natural history and Latin America's active role in it afford an opportunity to end the historiographic isolation of Latin America and situate it within world history.

  17. Biography of a technology: North America's power grid through the twentieth century

    NASA Astrophysics Data System (ADS)

    Cohn, Julie A.

    North Americans are among the world's most intense consumers of electricity. The vast majority in the United States and Canada access power from a network of transmission lines that stretch from the East Coast to the West Coast and from Canada to the Mexican Baja. This network, known as the largest interconnected machine in the world, evolved during the first two thirds of the twentieth century. With the very first link-ups occurring at the end of the 1890s, a wide variety of public and private utilities extended power lines to reach markets, access and manage energy resources, balance loads, realize economies of scale, provide backup power, and achieve economic stability. In 1967, utility managers and the Bureau of Reclamation connected the expansive eastern and western power pools to create the North American grid. Unlike other power grids around the world, built by single, centrally controlled entities, this large technological system emerged as the result of multiple decisions across eighty-five years of development, and negotiations for control at the economic, political, and technological levels. This dissertation describes the process of building the North American grid and the paradoxes the resulting system represents. While the grid functions as a single machine moving electricity across the continent, it is owned by many independent entities. Smooth operations suggest that the grid is a unified system; however, it operates under shared management and divided authority. In addition, although a single power network seems the logical outcome of electrification, in fact it was assembled through aggregation, not planning. Interconnections intentionally increase the robustness of individual sub-networks, yet the system itself is fragile, as demonstrated by major cascading power outages. Finally, the transmission network facilitates increased use of energy resources and consumption of power, but at certain points in the past, it also served as a technology of

    Due to the importance that the El Niño-Southern Oscillation (ENSO) has on rainfall over the tropical Americas, future changes in ENSO characteristics and teleconnections are important for regional hydroclimate. Projected changes to the ENSO mean state and characteristics, and the resulting impacts on rainfall anomalies over Central America, Colombia, and Ecuador during the twenty-first century are explored for several forcing scenarios using a suite of coupled atmosphere-ocean global climate models (AOGCMs) from the fifth phase of the Coupled Model Intercomparison Project (CMIP5). Mean-state warming of eastern tropical Pacific sea surface temperatures, drying of Central America and northern Colombia, and wetting of southwest Colombia and Ecuador are consistent with previous studies that used earlier versions of the AOGCMs. Current and projected future characteristics of ENSO (frequency, duration, amplitude) show a wide range of values across the various AOGCMs. The magnitude of ENSO-related rainfall anomalies are currently underestimated by most of the models, but the model ensembles generally simulate the correct sign of the anomalies across the seasons around the peak ENSO effects. While the models capture the broad present-day ENSO-related rainfall anomalies, there is not a clear sense of projected future changes in the precipitation anomalies.

    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.

    Hugo de Vries's mutation theory is now little more than a footnote to the history of biology, a failed theory that briefly led a few biologists astray. However, for the first quarter of the twentieth century it attracted considerable attention from both professional biologists and laypeople. De Vries's theory--together with the plant, Oenothera lamarckiana, that had supplied most of his evidence--became the focus of a surprising variety of imaginative hopes. Scientists and their various publics were fascinated by the utopian possibilities that the primrose seemed to offer, and their discussions shaped a public culture around biology that would help define the twentieth century as the "century of the gene." From a conventional history of science perspective (which, in the case of twentieth-century biology, often remains focused on the content of scientific theories and the professional communities that shaped them), the mutation theory seems unimportant. However, while De Vries's new theory of evolution ultimately failed to persuade the scientific community, it was much more important than is now realized, particularly because it helped make biology part of a wide variety of public debates. Understanding the mutation theory's story more fully suggests that we may need to rethink much of the rest of the century of the gene's history, to think less in terms of what happened in the lab and more about how biology came to function as public culture.

    The widespread influence exerted by the medical theories of Scottish doctor, John Brown, whose eponymously named Brunonianism radically simplified the ideas of his mentor, William Cullen, has not been generally recognised. However, the very simplicity of the Brunonian medical model played a key role in ensuring the dissemination of medical ideas about nervous irritability and the harmful effects of overstimulation in the literary culture of the nineteenth century and shaped early sociological thinking. This chapter suggests the centrality of these medical ideas, as mediated by Brunonianism, to the understanding of Romanticism in the nineteenth century, and argues that Brunonian ideas shaped nineteenth-century thinking about the effects of mass print culture in ways which continue to influence contemporary thinking about the effects of media.

    This historical article considers nursing's work for social justice in the 1960s civil rights movement through the lens of religious sisters and brothers who advocated for racial equality. The article examines Catholic nurses' work with African Americans in the mid-20th century that took place amid the prevailing social conditions of poverty and racial disempowerment, conditions that were linked to serious health consequences. Historical methodology is used within the framework of "bearing witness," a term often used in relation to the civil rights movement and one the sisters themselves employed. Two situations involving nurses in the mid-20th century are examined: the civil rights movement in Selma, Alabama, and the actions for racial justice in Chicago, Illinois. The thoughts and actions of Catholic sister and brother nurses in the mid-20th century are chronicled, including those few sister nurses who stepped outside their ordinary roles in an attempt to change an unjust system entirely.

    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.

  1. Weapon usage in attempted and completed parricides in nineteenth-century America: an archival exploration of the physical strength hypothesis.

    The "physical strength hypothesis" (PSH) predicts that where there is the greatest discrepancy in size and strength between offenders and victims, the former will use superior weaponry (e.g., firearms) to overcome structural imbalances against the latter. Using archival data from the New York Times and the Chicago Tribune, 1851-1899, this paper examines the weapons used in attempted and completed parricides in nineteenth-century America. Findings indicate that parricide offenders used firearms most frequently against their fathers while intimate contact methods were used against mothers. When gun usage was combined with level of intent in male offender patricides, where the greatest discrepancy in strength was expected, results indicate that spontaneous gun usage outnumbered premeditated gun usage, thus challenging the assumptions of the PSH. The data suggest that cultural factors such as methods of dispute resolution, weapon carrying, and alcohol consumption may be important factors in understanding parricides.

  2. Geologic and hydrologic hazards in glacierized basins in North America resulting from 19th and 20th century global warming

    Alpine glacier retreat resulting from global warming since the close of the Little Ice Age in the 19th and 20th centuries has increased the risk and incidence of some geologic and hydrologic hazards in mountainous alpine regions of North America. Abundant loose debris in recently deglaciated areas at the toe of alpine glaciers provides a ready source of sediment during rainstorms or outburst floods. This sediment can cause debris flows and sedimentation problems in downstream areas. Moraines built during the Little Ice Age can trap and store large volumes of water. These natural dams have no controlled outlets and can fail without warning. Many glacier-dammed lakes have grown in size, while ice dams have shrunk, resulting in greater risks of ice-dam failure. The retreat and thinning of glacier ice has left oversteepened, unstable valley walls and has led to increased incidence of rock and debris avalanches. ?? 1993 Kluwer Academic Publishers.

    2009-01-01

    This historical article considers nursing’s work for social justice in the 1960s civil rights movement through the lens of religious sisters and brothers who advocated for racial equality. The article examines Catholic nurses’ work with African Americans in the mid-20th century that took place amid the prevailing social conditions of poverty and racial disempowerment, conditions that were linked to serious health consequences. Historical methodology is used within the framework of “bearing witness,” a term often used in relation to the civil rights movement and one the sisters themselves employed. Two situations involving nurses in the mid-20th century are examined: the civil rights movement in Selma, Alabama, and the actions for racial justice in Chicago, Illinois. The thoughts and actions of Catholic sister and brother nurses in the mid-20th century are chronicled, including those few sister nurses who stepped outside their ordinary roles in an attempt to change an unjust system entirely.

    Since 2000, southwestern North America has experienced widespread drought. Lakes Powell and Mead are now at less than 50% of their reservoir capacity, and drought or fire-related states of emergency were declared this past summer by governors in six western states. As with other prolonged droughts, such as the Dust Bowl during the 1930s, aridity has at times extended from northern Mexico to the southern Canadian prairies. A synthesis of climatological and paleoclimatological studies suggests that a transition to a more arid climate may be occurring due to global warming, with the prospect of sustained droughts being exacerbated by the potential reaction of the Pacific Ocean to warming.

    Reform of the medical education in the early 20th century America caused many consequences in the various aspects of the medical fields as well as the improvement of the medical education itself such as the reinforcement of the laboratory training in the basic science courses and hospital instruction in the clinical courses. The reform brought about the direct or indirect elimination of the irregular sectarian practitioners and the minority groups such as black and women from the medical market place, established the concrete position of the regular physicians in the American society, reinforced the biomedical aspects which would become the general tendency in the 20th century Western medicine. And the author stressed that the reform was neither initiated nor invoked but just accelerated by the so-called Flexner Report of 1910, rather it had been performed through the processes of the interaction and struggle between the various contradictory trends, tendencies, and forces such as american Medical Association (AMA), some leading medical educators and scientists, medical colleges, and philanthropic foundations in the socio-cultural millieu gradually moving to favor the "science".

    2016-02-01

    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.

    For at least eight decades, researchers have analyzed the association between childhood poverty and cognitive development in different societies worldwide, but few of such studies have been carried out in Latin America. The aim of the present paper is to systematically review the empirical studies that have analyzed the associations between poverty and cognitive development in children under 18 years of age from Latin American and Caribbean countries between 2000 and 2015. This analysis takes into consideration the country where the work was conducted, the experimental and analytical design, sample size and composition, cognitive and poverty paradigms implemented, levels of analysis, and the inclusion of mediation analyses. Through these, we identify common patterns in the negative impact of poverty that have been repeatedly verified in the literature in other continents; we also call attention to a set of issues regarding sample, design, paradigms, impact, and mediation analyses that should be considered in future studies in the region.

    2009-09-01

    This article examines the study of natural history on the imperial periphery in late colonial Spanish America. It considers the problems that afflicted peripheral naturalists-lack of books, instruments, scholarly companionship, and skilled technicians. It discusses how these deprivations impacted upon their self-confidence and credibility as men of science and it examines the strategies adopted by peripheral naturalists to boost their scientific credibility. The article argues that Spanish American savants, deprived of the most up-to-date books and sophisticated instruments, emphasised instead their sustained experience of local nature and their familiarity with indigenous knowledge. It details how some creole naturalists, such as the Mexican José Antonio Alzate, questioned the applicability of European classificatory systems to American fauna and flora, and it analyses the complex relationship between natural science and creole patriotism.

    Newborn screening (NBS) in Latin America took its first steps in the mid-1970s. Nevertheless, many years elapsed before it achieved its integration within the public health care system and its systematic and continuous implementation under a programme structure. Latin American countries can be characterized not only by their great geographic, demographic, ethnic, economic and health system diversity, but also by their heterogeneity in NBS activities, which gives rise to variation in degree of organization: countries with optimal fulfilment (Cuba, Costa Rica, Chile, Uruguay); others rapidly expanding their coverage (Brazil, Mexico, Argentina); some others in a recent implementation phase (Colombia, Paraguay, Venezuela, Nicaragua, Peru); others with minimal, isolated and non-organized activities (Guatemala, Dominican Republic, Bolivia, Panama, Ecuador); and finally others without any NBS activities at all (El Salvador, Honduras, Haiti). Despite this disparity, a sustained and significant growth in NBS activities has become evident during the last decade, highlighted by implementation of new programmes, increase in coverage, expansion of NBS panels, increasing involvement of governmental and public health authorities, and integration of NBS teams through scientific societies and External Quality Assurance Schemes. Currently, congenital hypothyroidism (CH) is the most widely screened disease, followed by phenylketonuria, with organized NBS programmes for CH in 14 countries. Other diseases usually included in NBS programmes are screened in a lower rate. Every year, around 11.2 million infants are born in Latin America. During 2005, 49.3% of newborns were screened for CH, indicating that around 5.7 million newborns still did not have access to the benefits of NBS. PMID:17701285

    In 1952, the University of Michigan physiologist Robert Gesell shocked his colleagues at the business meeting of the American Physiological Society by reading a prepared statement in which he claimed that some of the animal experimentation being carried out by scientists was inhumane. He especially attacked the National Society for Medical Research (NSMR), an organization that had been founded to defend animal experimentation. This incident was part of a broader struggle taking place at the time between scientists and animal welfare advocates with respect to what restrictions, if any, should be placed on animal research. A particularly controversial issue was whether or not pound animals should be made available to laboratories for research. Two of the prominent players in this controversy were the NSMR and the Animal Welfare Institute, founded and run by Gesell's daughter, Christine Stevens. This article focuses on the interaction between these two organizations within the broader context of the debate over animal experimentation in the mid-twentieth century.

    Humanity faces an unprecedented challenge as our numbers grow, while Earth and its capacity to support us do not. People across the United States and around the world aspire to better lives for themselves and for their children: food, shelter, a safe and healthy environment, education, jobs, and other material needs and conveniences. Industries strive to produce more goods, farmers to grow more crops; and human demands on forests, fields, rivers, and oceans increase. Our challenge is to create a future in which prosperity and opportunity increase while life flourishes and pressures on oceans, earth, and atmosphere - the biosphere - diminish; to create, as the Council's vision suggests, "a life- sustaining Earth that supports "a dignified, peaceful, and equitable existence." It is a powerful vision, and the two co-chairs of the President's Council on Sustainable Development (PCSD), fervently believe it is achievable - a unifying and necessary goal for the boundless capacity of human ingenuity so manifest in America. This document addresses climate change, environmental management, metropolitan and rural strategies, and international leadership.

  16. A culture of technical knowledge: Professionalizing science and engineering education in late-nineteenth century America

    NASA Astrophysics Data System (ADS)

    Nienkamp, Paul

    This manuscript examines the intellectual, cultural, and practical approaches to science and engineering education as a part of the land-grant college movement in the Midwest between the 1850s and early 1900s. These land-grant institutions began and grew within unique frontier societies that both cherished self-reliance and diligently worked to make themselves part of the larger national experience. College administrators and professors encountered rapidly changing public expectations, regional needs, and employment requirements. They recognized a dire need for technically skilled men and women who could quickly adapt to changes in equipment and processes, and implement advances in scientific knowledge in American homes, fields, and factories. Charged with educating the "industrial classes in the several pursuits and professions in life," land-grant college supporters and professors sought out the most modern and innovative instructional methods. Combining the humanities, sciences, and practical skills that they believed uniquely suited student needs, these pioneering educators formulated new curricula and training programs that advanced both the knowledge and the social standing of America's agricultural and mechanical working classes.

  17. Analysis of Oceans' Influence on Spring Time Rainfall Variability Over Southeastern South America during the 20th Century

    2015-04-01

    Southeastern South America (SESA) rainfall presents large variability from interannual to multidecadal times scales and is influenced by the tropical Pacific, Atlantic and Indian oceans. At the same time, these tropical oceans interact with each other inducing sea surface temperature anomalies in remote basins through atmospheric and oceanic teleconnections. In this study we employ a tool from complex networks to analyze the collective influence of the three tropical oceans on austral spring rainfall variability over SESA during the 20th century. To do so we construct a climate network considering as nodes the observed Niño3.4, Tropical North Atlantic (TNA), and Indian Ocean Dipole (IOD) indices, together with an observed or simulated precipitation (PCP) index over SESA. The mean network distance is considered as a measure of synchronization among all these phenomena during the 20th century. The approach allowed to uncover large interannual and interdecadal variability in the interaction among nodes. In particular, there are two main synchronization periods characterized by different interactions among the oceanic and precipitation nodes. Whereas in the '30s El Niño and the TNA were the main tropical oceanic phenomena that influenced SESA precipitation variability, during the '70s they were El Niño and the IOD. Simulations with an Atmospheric General Circulation Model reproduced the overall behavior of the collective influence of the tropical oceans on rainfall over SESA, and allowed to study the circulation anomalies that characterized the synchronization periods. In agreement with previous studies, the influence of El Niño on SESA precipitation variability might be understood through an increase of the northerly transport of moisture in lower levels and advection of cyclonic vorticity in upper levels. On the other hand, the interaction between the IOD and PCP can be interpreted in two possible ways. One possibility is that both nodes (IOD and PCP) are forced

    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

    1986-01-01

    The mid-19th century saw the emergence of a major medical innovation, namely, the rise of the state lunatic asylum. Beginning in the northeast, the phenomenon spread rapidly westwards. By 1875 no fewer than 71 mental hospitals were opened in 32 existing states. Although premised upon belief in the efficacy of 'moral and humane' treatment, the asylums soon became custodial rather than therapeutic institutions. Average size continually increased; some accommodated well over 2000 patients. The provision of more asylums, and broadened definitions of insanity, generated increasing patient numbers which, in turn, caused public consternation and fear of increasing 'madness' in the population. Geographic analysis of admissions in 18 U.S. states and two Canadian provinces reveals the universality of distance decay around the asylums, and demonstrates that hospital service-area cones were predominantly local in effect. Thus the 'state' asylum was in reality a local institution. The deinstitutionalization movement of recent decades is apparently bringing to a closure a 100-year cycle of incarceration-decarceration of the mentally ill. Nevertheless, whether patients are geographically concentrated or dispersed, the influence of distance decay remains a relevant consideration.

    Two large earthquakes took place in the later part of the XIX century in southern Peru and northern Chile, these are the August 13, 1868, and the May 9, 1877 (local time), events. Their estimated magnitudes are of the order of 9 rupturing contiguous segments of nearly 500 km each. Both of them accommodated the convergence between Nazca and South American plates producing large seafloor and coastal elevation changes generating significant tsunamis that affected most of the coastlines of the Pacific basin. Reported local runups reached 20 m. Both trans-pacific tsunamis were recorded at one tide gage in Fort Point, in the Presidio area of San Francisco Bay, California. Records at Sausalito (approximately 6 km away from Fort Point) for the 1877 event mimic the signal recorded at Fort Point. Here we report on the characteristics of these tide gage records and compare them to the recent record of the June 2001 Mw=8.4 earthquake that ruptured a fraction of the 1868 event. Numerical simulations of the tsunamis have been constructed. The area to the south of the 2001 event and north of Antofagasta - Tocopilla in Chile (17°S-22°S), has not been subjected to large earthquakes since the 1868-1877 sequence.

    Statistically downscaled climate projections from nine global climate models (GCMs) are used to force a snow accumulation and ablation model (SNOW-17) across the central-eastern North American Landscape Conservation Cooperatives (LCCs) to develop high-resolution projections of snowfall, snow depth, and winter severity index (WSI) by the mid- and late 21st century. Here, we use projections of a cumulative WSI (CWSI) known to influence autumn-winter waterfowl migration to demonstrate the utility of SNOW-17 results. The application of statistically downscaled climate data and a snow model leads to a better representation of lake processes in the Great Lakes Basin, topographic effects in the Appalachian Mountains, and spatial patterns of climatological snowfall, compared to the original GCMs. Annual mean snowfall is simulated to decline across the region, particularly in early winter (December-January), leading to a delay in the mean onset of the snow season. Due to a warming-induced acceleration of snowmelt, the percentage loss in snow depth exceeds that of snowfall. Across the Plains and Prairie Potholes LCC and Upper Midwest and Great Lakes LCC, daily snowfall events are projected to become less common, but more intense. The greatest reductions in the number of days per year with a present snowpack are expected close to the historical position of the -5°C isotherm in DJFM, around 44°N. The CWSI is projected to decline substantially during December-January, leading to increased likelihood of delays in timing and intensity of autumn-winter waterfowl migrations.

Alongside knowledge of a magical or religious nature, and exotic ingredients for the recipes, this work also contains the unmistakable presence of Hippocratic and Galenic conceptions and a growing empiricism, characteristic of the scientific transformations seen in the eighteenth century. The analysis of this work also prompts reflections about the diffusion, circulation and production of pharmacological and medical knowledge in the first half of the eighteenth century within the missions and colleges installed in the area that was the Jesuit Province of Paraguay, southern America.

    The first International Conference on Molecular Beam Epitaxy (IC-MBE) was held in Paris in 1978, chaired by Alfred Y. Cho. Every other year since, with the exception of a four-year break after the initial meeting, the IC-MBE has been held in European, Asian, and North American venues. The 18th and latest IC-MBE was held in Flagstaff, Arizona, USA, September 7-12, 2014, and was chaired by Yong-Hang Zhang (Arizona State University). MBE is an advanced crystal growth method that benefits areas from the study of fundamental physics, all the way through the production of devices used in countless fields. IC-MBE brings together researchers from all over the world, and is the premier forum for scientific and technological exchange among researchers investigating all types of materials growth using the MBE technique.

    The 18th European Symposium on Quantitative Structure-Activity Relationships (QSAR) took place in Rhodes, Greece, on 19 - 24 September 2010. It was organized by the Hellenic Society of Medicinal Chemistry and the Cheminformatics and QSAR Society, and co-sponsored by the European Federation of Medicinal Chemistry. The conference was thematically dedicated to discovery informatics and drug design and addressed the impact of informatics in all its variants (chemoinformatics, bioinformatics, pharmacoinformatics) on drug discovery in the broader context of biological complexity. The latest scientific and technological advances in QSAR as tools for the discovery of new, safer and more efficacious drugs were discussed during the meeting. This paper highlights the most important outcomes of the symposium, commenting briefly on some of the key presentations.

    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.

  11. Education and outreach challenges for the 21st century -- Promoting source reduction and recycling in a changing America

    Promoting source reduction and recycling is become increasingly more challenging as the demographics of America change. By the middle of the next century, non-Hispanic whites will be a minority in a number of states, including California. More than 30 million people already speak a language other than English at home, and in some cities, such as San Francisco and Miami, more than 40% of residents speak a language other than English. Motivating residents to practice source reduction and recycling will require an increasing sensitivity to multi-culturalism and multi-lingual outreach will become essential. Designing public education programs that are successful will require significant changes in the way outreach is planned and implemented. The San Francisco Recycling Program has long worked on developing not just multi-lingual, but also multi-cultural outreach to motivate residents to reduce waste and recycle. The program conducts outreach in 6 languages, and has direct contact with more than 50,000 households a year, including using a multilingual phone bank operation that reaches 30,000 households a year. Other outreach programs include neighborhood campaigns with incentives; street signs; exhibits; door to door campaigns; direct mail; field trips, assembly programs and presentations for students; web sites; trilingual hotlines; and multilingual brochures delivered to every new mover. Given limited resources, partnerships have also been a major vehicle for expanding the program's outreach. For example, the San Francisco Recycling Program has spearheaded a regional waste prevention partnership that includes 110 cities and counties, 400 supermarkets and other private partners to promote source reduction. This program has had documented impact on shopping behavior in the Bay Area.

    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.

    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.

(1731-1787), teacher at the Jesuit Colegio de Santo Tom'as (a college-level institution in Guadalajara before the university opening), inside of the vellum bounded volume is a unbounded folio containing instructions on how to build a thermometer. In this work are discussed some evidences of the belonging of such folio to the manuscript in spite of their differences (it is written in Spanish not in Latin as the whole), we also describe the process to construct the thermometer and how could be the experimental part of the physics course. Also is briefly exposed the importance of the educational role of Clavigero as a builder of the concept of mexicanity.

    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.

    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.

    In the early 18th century, Johann Friedrich Böttger, an alchemist recently arrived in Dresden, was assigned to ceramic experimentation under the orders of Augustus the Strong, Elector of Saxony and King of Poland. The Elector and his advisors hoped to discover the secret of making hard paste porcelain like the wares imported into Europe from China and Japan. In 1706-1707, Böttger produced his first ceramic body, a red stoneware similar to the wares produced in Yixing, China. The first objects were made following the forms of chinese prototypes or European metalwork of the period. Recently, the authenticity of a number of `Böttger' objects in various museums and private collections in North America and Europe has been questioned. To aide in resolving these questions several non-destructive analytical techniques have been employed, the most important being PIXE. This report is on an initial study of 25 objects with 16 elements from Al to Zr and Pb being analysed. The results strongly suggest three different groupings, one of objects from the Meissen factory during the 20th century, one from the work of Böttger himself early in the 18th century and one from an as yet unknown time period and site. The first two groups were previously identified by one of the authors (C.N.).

Historically, individualism, self-reliance, and an orientation towards youth have been cherished values reflecting...our national heritage and tradition dating from the 18th through the mid-20th century. However, America is no longer a ¿young' nation. Rather, we are an ¿aging' population, as we show in our analysis of demographic transitions reviewed in this paper. The phenomenon of ¿cultural (or structural) lag' is discussed in two different contexts: first--the context of the aging family; and second--the context of ethnic/racial minority groups. Finally, some of the relevant public policy responses to aging are described. We look at government programs in four major categories, namely, (1) income; (2) health care; (3) social services; and (4) housing."

  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.

    Northern peatlands contain a large terrestrial carbon pool that plays an important role in the Earth's carbon cycle. A considerable fraction of this carbon pool is currently in permafrost and is biogeochemically relatively inert; this will change with increasing soil temperatures as a result of climate warming in the 21st century. We use a geospatially explicit representation of peat areas and peat depth from a recently-compiled database and a geothermal model to estimate northern North America soil temperature responses to predicted changes in air temperature. We find that, despite a widespread decline in the areas classified as permafrost, soil temperatures in peatlands respond more slowly to increases in air temperature owing to the insulating properties of peat. We estimate that an additional 670 km3 of peat soils in North America, containing ~33 Pg C, could be seasonally thawed by the end of the century, representing ~20 % of the total peat volume in Alaska and Canada. Warming conditions result in a lengthening of the soil thaw period by ~40 days, averaged over the model domain. These changes have potentially important implications for the carbon balance of peat soils.

    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.

Four distinct reanalyses are considered, two of which cover the entire twentieth-century: NOAA-CIRES Twentieth Century Reanalysis v2 (NOAA-20C) and ECMWF ERA-20C. Calculations are done separately for the OND and JFM-season and, for comparison with previous studies, for the ONDJFM-season as a whole. Comparing the AR-counts from NOAA-20C and ERA-20C with a running 31-year window looping through 1900-2010 reveals differences in the climatological mean and inter-annual variability which, at the start of the twentieth-century, are much more pronounced in western North America than in Europe. Correlating European AR-counts with the North Atlantic Oscillation (NAO) reveals a pattern reminiscent of the well-know precipitation dipole which is stable throughout the entire century. A similar analysis linking western North American AR-counts to the North Pacific index (NPI) is hampered by the aforementioned poor reanalysis agreement at the start of the century. During the second half of the twentieth-century, the strength of the NPI-link considerably varies with time in British Columbia and the Gulf of Alaska. Considering the period 1950-2010, AR-counts are then associated with other relevant large-scale circulation indices such as the East Atlantic, Scandinavian, Pacific-North American and West Pacific patterns (EA, SCAND, PNA and WP). Along the Atlantic coastline of the Iberian Peninsula and France, the EA-link is stronger than the NAO-link if the OND season is considered and the SCAND-link found in northern Europe is significant during both seasons. Along the west coast of North America, teleconnections are generally stronger during JFM in which case the NPI-link is significant in any of the five considered

  16. Dynamics and mechanisms of decadal variability of the Pacific-South America mode over the 20th century

    2016-06-01

    In this paper, decadal variability of the Pacific-South America (PSA) mode is examined from year 1871 to 2008 based on the newly developed ocean and atmosphere reanalysis products. The PSA mode, mirroring the Pacific-North America mode in the Northern Hemisphere, emerges as the second EOF mode of 500 mb geopotential height anomalies. The mode displays substantial interannual-decadal variability with distinct timescales between 3-8 and 10-18 years, respectively. The decadal variability of the PSA mode is found to be associated with the coupled ocean-atmosphere interaction over the subtropical South and tropical Pacific. The subduction of the subtropical temperature anomalies in the South Pacific in conjunction with the tropical-subtropical atmospheric teleconnection plays important role in the decadal variability of the PSA mode.

  17. Seasonal changes of extreme climate indices in Mexico and Central America during the 21st century using CMIP5

    We evaluated historical (1961-2000) and climate change projections of temperature and precipitation from 15 general circulation models (GCMs) of the Climate Model Intercomparison Project phase 5 (CMIP5) for Mexico and Central America. Annual cycles, interannual variations and seasonal extreme percentiles (P10 and P90) of temperature and precipitation were validated with observed data from the Climatic Research Unit (CRU). Climate change scenarios for the mean GCM ensemble (ens_GCM) were obtained for the 2075-2099 period, relative to 1961-2000, for low (RCP4.5) and high (RCP8.5) radiating forcings. The ens_GCM was obtained by the Reliability Ensemble Averaging (REA) technique (Giorgi and Mearns 2001). Maximum temperature (Tmax) is underestimated (~2oC) by the ens_GCM in almost all Mexico, while minimum temperature (Tmin) is overestimated. Part of the underestimation may be related to the excess of rainfall that many models produce, especially in autumn and winter. For example, in the monsoon region, the models fail to produce the retreat of the summer rains in autumn, a feature also observed in the CMIP3 models. The ens_GCM overestimates rainfall in the semiarid regions of Northern Mexico and the Southwestern United States, but underestimates rainfall in southern Mexico and Central America, where extreme rainfall (P90 in JJA) can be larger than 8 mm d-1. Seasonal thresholds for extreme climatic indices (P90 and P10) were produced for Mexico and Central America. The largest observed P90 threshold for Tmax from the CRU dataset occurs in JJA along the US-Mexico border (~35-40oC), where the ens_GCM underestimates it by ~5oC; in some coastal regions of Central America the largest thresholds are between 30-35oC. The results for the RCP8.5 scenario show that the P90 threshold for Tmax in JJA may increase (>3oC) in almost all the study region, and >5oC along the Sierra Madre Occidental in the monsoon region. This may have important implications for the monsoon dynamics. The

    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).

    2012-01-01

    America experienced a genuinely vast development of biomedical science in the early decades of the twentieth century, which in turn impacted the community of academic psychiatry and changed the way in which clinical and basic research approaches in psychiatry were conceptualized. This development was largely based on the restructuring of research universities in both of the USA and Canada following the influential report of Johns Hopkins-trained science administrator and politician Abraham Flexner (1866–1959). Flexner's report written in commission for the Carnegie Foundation for the Advancement of Teaching in Washington, DC, also had a major influence on complementary and alternative medicine (CAM) in psychiatry throughout the 20th century. This paper explores the lasting impact of Flexner's research published on modern medicine and particularly on what he interpreted as the various forms of health care and psychiatric treatment that appeared to compete with the paradigm of biomedicine. We will particularly draw attention to the serious effects of the closing of so many CAM-oriented hospitals, colleges, and medical teaching programs following to the publication of the Flexner Report in 1910.

    In mid-19th Century, cholera was epidemic throughout the world. Small towns of the American Midwest were not spared. The disease was blamed on miasmas arising from local causes, so flight from affected localities were logical and common. Flight, added to mortality, caused virtual depopulation of many small towns. Drinking water was drawn from rivers or shallow wells, often near seeping cesspools. Local merchants tried unsuccessfully to calm panic by suppressing information. Cholera was not good for business. Business was depressed. Organized religion thrived. National and state days of prayer were appointed to appease an angry God. During these frightening times, the people learned nothing about the infectiousness of cholera or about its prevention through sanitation. Their experiences tended to reinforce their belief in miasmas or divine retribution. The great epidemics of mankind describe human behavior in times of unavoidable and incurable crisis. Nineteenth Century cholera experiences illustrate a people's reaction to catastrophic disease, which they believed was incurable and unpreventable. PMID:18596846

    The global impact on public health of elevated arsenic (As) in water supplies is highlighted by an increasing number of countries worldwide reporting high As concentrations in drinking water. In Latin America, the problem of As contamination in water is known in 14 out of 20 countries: Argentina, Bolivia, Brazil, Chile, Colombia, Cuba, Ecuador, El Salvador, Guatemala, Honduras, Mexico, Nicaragua, Peru and Uruguay. Considering the 10 μg/L limit for As in drinking water established by international and several national agencies, the number of exposed people is estimated to be about 14 million. Health effects of As exposure were identified for the first time already in the 1910s in Bellville (Córdoba province, Argentina). Nevertheless, contamination of As in waters has been detected in 10 Latin American countries only within the last 10 to 15 years. Arsenic is mobilized predominantly from young volcanic rocks and their weathering products. In alluvial aquifers, which are water sources frequently used for water supply, desorption of As from metal oxyhydroxides at high pH (>8) is the predominant mobility control; redox conditions are moderate reducing to oxidizing and As(V) is the predominant species. In the Andes, the Middle American cordillera and the Transmexican Volcanic Belt, oxidation of sulfide minerals is the primary As mobilization process. Rivers that originate in the Andean mountains, transport As to more densely populated areas in the lowlands (e.g. Rímac river in Peru, Pilcomayo river in Bolivia/Argentina/Paraguay). In many parts of Latin America, As often occurs together with F and B; in the Chaco-Pampean plain As is found additionally with V, Mo and U whereas in areas with sulfide ore deposits As often occurs together with heavy metals. These co-occurrences and the anthropogenic activities in mining areas that enhance the mobilization of As and other pollutants make more dramatic the environmental problem.

    The XVII International Conference on Strings, Particles and Cosmology, PASCOS 2012, was held in the City of Mérida, Mexico, from June 3-8, 2012. The conference series is aimed at exploring the interface and interplay between particle physics, string theory and cosmology. With the advent of new data, the emphasis of the XVIII edition of PASCOS was on phenomenology and the interpretation of recent observational and experimental results. The conference followed the format of previous conferences in this series, with plenary reviews and contributed presentations in parallel sessions. The lectures covered a wide range of subjects which included: Dark matter and dark energy, flavor physics and CP violation, neutrino physics, supersymmetry, Higgs physics, baryogenesis and EDMs, supergravity, high energy cosmic rays, string and F-theory GUTs, and string phenomenology. This is the first time that PASCOS was held in Latin America. The aim to do it in Mexico was to engage the Latin American community and thus to bring the conference to a wider and different audience, a goal which was thoroughly achieved. The venue was held at the Hotel Fiesta Americana in the beautiful city of Mérida. The social events included a reception with typical local food at the Katun restaurant, conference dinner at the historical Quinta Montes Molina, and an excursion to the archeological site of Dzibilchaltún including a swim at the famous cenote. PASCOS 2012 was possible thanks to the generous support of the following sponsors: CONACyT (Consejo Nacional de Ciencia y Tecnología), UNAM (Universidad Nacional Autónoma de México: Consejo Técnico de la Investigación Científica, Instituto de Ciencias Nucleares, Instituto de Física), Cinvestav, (Centro de Estudios Avanzados del IPN: U.

    C4 grasses currently cover ~18% of the earth's surface and are economically important as food sources, but their distributions are likely to change with future climate changes. As a result of the opposing impacts of atmospheric CO2 and temperature on C3 and C4 physiology, future changes to the productivity and distributions of these grasses have remained unclear. We have used past and present tooth enamel, collagen, and bone carbon isotope ratios (δ13C) of Bison and Mammoth grazers to record the δ13C values of their diet, and the abundance of C3 and C4 vegetation in these habitats. Thus, the δ13C values of bison and mammoth tissues serve as a proxy for vegetation composition across North America through time. We combine these isotope data with ensemble CMIP5 climate model outputs, eight different climatic and fire predictor variables and advanced statistical techniques to model the spatial distribution of C3 and C4 grasses up through the year 2100 for two different emissions scenarios. Using the Random Forest algorithm, our model explains 91% of the spatial and temporal isotopic variability in bison and mammoth tissues and infers that mean summer temperature is the strongest predictor of all climate variables. For the emission scenario RCP4.5, in which atmospheric CO2 levels are predicted to rise to ~540 ppm by 2100, we find decreases in the abundance of C4 grasses of up to 30% in the south-central Great Plains and the Florida peninsula, and increases of up to 50% in the northern Great Plains. For the RCP8.5 scenario, in which atmospheric CO2 levels are expected to rise to ~930 ppm by 2100, our model predicts minor decreases in the abundance of C4 grasses in Texas and Oklahoma, but increases of 30-50% over the majority of the Great Plains. The overall effect of these changes is a homogenization of the Great Plains ecoregion in terms of grassland type distributions, and the loss of the highest abundance of C4 ecosystems of the panhandles of Texas, Oklahoma and

    The issue of the reciprocal relationship between health and development has recently taken on greater importance in Latin America and the Caribbean (LAC), given the persistence of extreme poverty and the political and social difficulties due to macroeconomic imbalances and crises of governance. This piece reviews concepts of sustainable human development, social determinants of health in general and of health inequities in particular (gender, ethnic group, income level), and the relationship between health and economic growth in the medium term and the long term. An analysis is made of how persistent poverty in countries of LAC relates to disparities in health conditions, access to health services, and health care financing, as well as to such health determinants as nutrition and environmental sanitation. Health inequities most strongly affect the most excluded and vulnerable sectors of the population. In the face of this situation, the author stresses that putting a priority on health inequities is vital to safeguarding the governability and the social and political stability of countries in LAC in the next decade.

    British by birth Allan Cyril Brooks (1869-1946) emigrated to Canada in the 1880s, and became one of the most important North American bird illustrators during the first half of the twentieth century. Brooks was one of the leading ornithologists and wildlife collectors of the time; he corresponded extensively with other ornithologists and supplied specimens to many major North American museums. From the 1890s on he hoped to support himself by painting birds and mammals, but this was not possible in Canada at that time and he was forced to turn to American sources for illustration commissions. His work can be compared with that of his contemporary, the leading American bird painter Louis Agassiz Fuertes (1874-1927), and there are striking similarities and differences in their careers. This paper discusses the work of a talented, self-taught wildlife artist working in a North American milieu, his difficulties and successes in a newly developing field, and his quest for Canadian recognition.

    The life of 18th century astronomer, craftsman, and patriot David Rittenhouse is detailed. As a craftsman, he distinguished himself as one of the foremost builders of clocks. He also built magnetic compasses and surveying instruments. The finest examples of his craftsmanship are considered two orreries, mechanical solar systems. In terms of astronomical observations, his best-known contribution was his observation of the transit of Venus in 1769. Rittenhouse constructed the first diffraction grating. Working as Treasurer of Pennsylvania throughout the Revolution, he became the first director of the Mint in 1792. Astronomical observations in later life included charting the position of Uranus after its discovery.

    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

    This work questions the assumption that population policies in Latin America and the Caribbean are closely related to population growth, identifies common obstacles to population policies, and recommends actions to increase the efficacy of population policies. The demographic transition has occurred in Latin American countries with widely varying levels of economic development, cultural traditions, and family planning programs. The governments of the region that regard their rates of population growth and fertility as satisfactory seldom intervene to modify them. The demographic transition is well underway in all these countries except Guatemala and Paraguay. A diverse array of strategies has been used by the countries that have achieved significant fertility reductions, ranging from family planning services provided through the national health system in Mexico to key roles by the private and commercial sectors and intensive use of the mass media in Brazil. Governments adopting population policies defined various institutional forms for them, ranging from small technical units at a high level to interministerial councils. Institutionalization of population policies created high hopes for integration of population concerns into development strategies, but performance has largely failed to meet expectations, both because of the fragility and inferior status in the government bureaucracy of policy structures, and because of their inability to develop effective programs integrating population and development. The economic crisis of the 1980s lowered the priority of population themes. Political instability, lack of adequate human resources and financing, limited decision making capacity, and failure to establish strong interinstitutional ties have all been factors in the disappointing results of population policies. The difficulty of pinpointing exactly what constitutes the population policy and the tendency to equate population policy and family planning have been

    The phasing of winter-to-summer precipitation anomalies in the North American monsoon (NAM) region 2 (113.25 deg W-107.75 deg W, 30 deg N-35.25 deg N-NAM2) of southwestern North America is analyzed in fully coupled simulations of the Last Millennium and compared to tree ring reconstructed winter and summer precipitation variability. The models simulate periods with in-phase seasonal precipitation anomalies, but the strength of this relationship is variable on multidecadal time scales, behavior that is also exhibited by the reconstructions. The models, however, are unable to simulate periods with consistently out-of-phase winter-to-summer precipitation anomalies as observed in the latter part of the instrumental interval. The periods with predominantly in-phase winter-to-summer precipitation anomalies in the models are significant against randomness, and while this result is suggestive of a potential for dual-season drought on interannual and longer time scales, models do not consistently exhibit the persistent dual-season drought seen in the dendroclimatic reconstructions. These collective findings indicate that model-derived drought risk assessments may underestimate the potential for dual-season drought in 21st century projections of hydroclimate in the American Southwest and parts of Mexico.

    We investigate the combined impact of ENSO and PDO on North American winter climate in current and future climate projections from 11 global models in the Climate Model Intercomparison Project Phase 5 (CMIP5) dataset. We first analyze winter sea surface temperature, sea level pressure (SLP) and precipitation anomalies for the historical period 1951-2005, and find that the CMIP5 models reproduce well the constructive interference between ENSO and the PDO compared to observations (i.e. positive ENSO and PDO or negative ENSO and PDO). On the other hand, the destructive interference (positive ENSO and negative PDO or negative ENSO and positive PDO) is less accurately reproduced. Consistently with observations, ENSO events show generally more impact on North American winter climate than PDO events, although there is a robust increase of rainfall in the Southeastern US during the negative PDO phase. For the twenty first century projections, we focus on the 2050-2099 period under the RCP8.5 greenhouse gas concentration scenario and we find an overall strengthening of both the ENSO and PDO signals, and particularly the PDO one, on the SLP and related teleconnections. This results in an enhanced influence of the negative PDO phase on flood conditions in the Southeastern United States, and in drier conditions over the Southwest coasts of North America.

    The formation of new and functional structural components of several organs, such as parotid glands, can be influenced by the glycocode. This study analyzed the glycobiology of parotid salivary gland tissue during fetal development using specific biochemical probes (lectins and antibodies). Eleven parotid gland samples from human fetuses were obtained from spontaneous abortions at 14-28 weeks of gestation, and tissue sections were analyzed for lectin histochemistry and immunohistochemistry. From the 18th to 26th week, Canavalia ensiformis agglutinin, wheat germ agglutinin, Ulex europaeus agglutinin-I, peanut agglutinin, Sambucus nigra agglutinin, and Vicia villosa agglutinin lectin staining were predominantly observed in the apical and/or basement membranes of the ducts and tubulo-acinar units. Moreover, the presence of galectin-1 was found in the membrane, cytoplasm, and nucleus of both structures. Conversely, Gal-3 and mucin-1 were restricted to the glandular ducts. The lectin staining pattern changed during the weeks evaluated. Nevertheless, the carbohydrate subcellular localization represented a key factor in the investigation of structural distribution profiles and possible roles of these glycans in initial parotid gland development. These findings are defined by their high biological value and provide an important base for the development of subsequent studies. (J Oral Sci 58, 353-360, 2016). PMID:27665974

    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.

    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.

    Interannual climate variations have been important drivers of wildfire occurrence in ponderosa pine forests across western North America for at least 400 years, but at finer scales of mountain ranges and landscapes human land uses sometimes over-rode climate influences. We reconstruct and analyse effects of high human population densities in forests of the Jemez Mountains, New Mexico from ca 1300 CE to Present. Prior to the 1680 Pueblo Revolt, human land uses reduced the occurrence of widespread fires while simultaneously adding more ignitions resulting in many small-extent fires. During the 18th and 19th centuries, wet/dry oscillations and their effects on fuels dynamics controlled widespread fire occurrence. In the late 19th century, intensive livestock grazing disrupted fuels continuity and fire spread and then active fire suppression maintained the absence of widespread surface fires during most of the 20th century. The abundance and continuity of fuels is the most important controlling variable in fire regimes of these semi-arid forests. Reduction of widespread fires owing to reduction of fuel continuity emerges as a hallmark of extensive human impacts on past forests and fire regimes.This article is part of the themed issue 'The interaction of fire and mankind'.

    A new drought atlas has been developed for subtropical North America, including the entire Republic of Mexico. This Mexican Drought Atlas (MXDA) is based on 251 tree-ring chronologies, including 82 from Mexico and another 169 from the southern U.S. and western Guatemala. Point-by-point principal components regression was used to reconstruct the self-calibrating Palmer Drought Severity Index (PDSI) for June-August. Calibration and verification statistics were improved over what was previously possible with the North American Drought Atlas, which was based on fewer chronologies only in Mexico. The MXDA will be served on the web with analytical tools for composite, correlation, and congruence analyses. The new PDSI reconstructions provide a more detailed estimation of decadal moisture regimes over the past 2000 years, but are most robust after 1400 AD, when several chronologies are available across Mexico. Droughts previously identified in a subset of chronologies are confirmed and their spatial impact quantified in the new reconstructions. This includes the intense drought of the mid-15th Century described in Aztec legend, the 16th Century megadrought, and "El Año del Hambre", one of the worst famines in Mexican history. We also use the best replicated portion of the MXDA in the 18th and 19th Centuries to reconstruct moisture anomalies during key time periods of Mexican turmoil (e.g., the Mexican War of Independence).

    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.

    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.

    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. PMID:19855125

    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.

    The age-markers described at the adult acetabulum by Rissech et al. (J Forensic Sci 51 (2006) 213-229) were scored in the Spitalfields collection of skeletons of documented age and sex (N = 161). The purpose of the work was as a contribution to the evaluation of the general utility of these markers for estimating age at death. To this end, their relationship both with age, and with some other factors, was investigated. The latter comprised sex, general tendency toward bone formation in periarticular soft tissue (as measured by the occurrence of diffuse idiopathic skeletal hyperostosis), and occupation (as documented for some of the males). Of the seven Rissech et al. variables, only four were found to show a statistically significant relationship with age. The correlation between a composite score derived from a linear combination of these four variables, and age was similar to or greater than correlations between age and composite scores based on other age indicators reported in the literature for Spitalfields. Male acetabula aged at a greater rate than those of females. There was no relationship with the occurrence of DISH, but for occupation, those in nonmanual professions showed greater acetabular scores-for-age than those in manual trades.

    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.

We observed significant differences between Boni Blacks and Wayana Indians, having respectively 10.3% versus 0% of high antibody titers. The Hmong, recent refugees from Kampuchea, exhibited an intermediate level (3.5%) of infection. These results favour an African origin of HTLV-1 and raise, for the Hmong, the question of an infection acquired in Guiana.

  3. Spatial trends in S and Cl in ash leachates of the May 18th, 1980 eruption of Mt. St Helens

    It has long been known that surficial deposits of salts and acids on volcanic ash particles derive from interactions of ash with sulphur and halide species within the eruption plume and volcanic cloud. These compounds are mobilised as ash particles are wetted, and beneficial or detrimental environmental and health impacts may be induced where the most concentrated solutions are produced. However, limited mechanistic understanding of gas-ash interactions currently precludes prediction of the spatial distribution or variation in leachate chemistry and concentration following an eruption. Sampling and leachate analysis of freshly-fallen ash therefore offers the sole method by which such variations can be observed. Previous ash leachate studies often involve a limited number of ash samples, and utilise a 'one-dimensional' analysis that considers variation in terms of absolute distance from the source volcano. Here, we demonstrate that extensive sampling and a 'two-dimensional' analysis can uncover more complex spatial trends. We compiled over 358 leachate compositions from the May 18th 1980 eruption of Mt. St. Helens. Of the water-extracted leachates, only 95 compositions from ash sampled at 45 localities between 35 and 1129 km from the volcano are sufficiently documented to be retrospectively comparable. To consider the effects of intra-deposit variability, we calculated average concentrations of leachate data within 11×22 km grid cells across the region, and defined a data quality parameter to reflect confidence in the derived values. To investigate any dependence of leachate composition on the grain size distribution, we generated an interpolated map of geometric specific surface area variation across the deposit, normalising ash leachate data to the calculated specific surface area at the corresponding sampling location. The data treatment identifies S and Cl enrichments in proximal blast deposits; relatively constant Cl concentrations across the ashfall deposits

  7. Southeast Asian Mega-Droughts of the Past 5 Centuries from Tree Rings and Historical Records

    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

    2014-11-01

    Global warming is expected to increase the frequency and intensity of droughts in the twenty-first century, but the relative contributions from changes in moisture supply (precipitation) versus evaporative demand (potential evapotranspiration; PET) have not been comprehensively assessed. Using output from a suite of general circulation model (GCM) simulations from phase 5 of the Coupled Model Intercomparison Project, projected twenty-first century drying and wetting trends are investigated using two offline indices of surface moisture balance: the Palmer Drought Severity Index (PDSI) and the Standardized Precipitation Evapotranspiration Index (SPEI). PDSI and SPEI projections using precipitation and Penman-Monteith based PET changes from the GCMs generally agree, showing robust cross-model drying in western North America, Central America, the Mediterranean, southern Africa, and the Amazon and robust wetting occurring in the Northern Hemisphere high latitudes and east Africa (PDSI only). The SPEI is more sensitive to PET changes than the PDSI, especially in arid regions such as the Sahara and Middle East. Regional drying and wetting patterns largely mirror the spatially heterogeneous response of precipitation in the models, although drying in the PDSI and SPEI calculations extends beyond the regions of reduced precipitation. This expansion of drying areas is attributed to globally widespread increases in PET, caused by increases in surface net radiation and the vapor pressure deficit. Increased PET not only intensifies drying in areas where precipitation is already reduced, it also drives areas into drought that would otherwise experience little drying or even wetting from precipitation trends alone. This PET amplification effect is largest in the Northern Hemisphere mid-latitudes, and is especially pronounced in western North America, Europe, and southeast China. Compared to PDSI projections using precipitation changes only, the projections incorporating both

    Background American Creole cattle presumably descend from animals imported from the Iberian Peninsula during the period of colonization and settlement, through different migration routes, and may have also suffered the influence of cattle directly imported from Africa. The introduction of European cattle, which began in the 18th century, and later of Zebu from India, has threatened the survival of Creole populations, some of which have nearly disappeared or were admixed with exotic breeds. Assessment of the genetic status of Creole cattle is essential for the establishment of conservation programs of these historical resources. Methodology/Principal Findings We sampled 27 Creole populations, 39 Iberian, 9 European and 6 Zebu breeds. We used microsatellite markers to assess the origins of Creole cattle, and to investigate the influence of different breeds on their genetic make-up. The major ancestral contributions are from breeds of southern Spain and Portugal, in agreement with the historical ports of departure of ships sailing towards the Western Hemisphere. This Iberian contribution to Creoles may also include some African influence, given the influential role that African cattle have had in the development of Iberian breeds, but the possibility of a direct influence on Creoles of African cattle imported to America can not be discarded. In addition to the Iberian influence, the admixture with other European breeds was minor. The Creoles from tropical areas, especially those from the Caribbean, show clear signs of admixture with Zebu. Conclusions/Significance Nearly five centuries since cattle were first brought to the Americas, Creoles still show a strong and predominant signature of their Iberian ancestors. Creole breeds differ widely from each other, both in genetic structure and influences from other breeds. Efforts are needed to avoid their extinction or further genetic erosion, which would compromise centuries of selective adaptation to a wide range of

    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.

    A 137 m ice core drilled in 1999 from Eastern Bolivian Andes at the summit of Nevado Illimani (16º 37' S, 67º 46' W, 6350 m asl) was analyzed at high temporal resolution, allowing a characterization of trace elements in Andean aerosol trapped in the ice during the 20th century. The upper 50 m of the ice core were dated by multi-proxy analysis of stable isotopes (d18O and d2H), 137Cs and Ca+2 content, electrical conductivity, and insoluble microparticle content, together with reference historical horizons from atmospheric nuclear tests and known volcanic eruptions. This 50 m section corresponds to a record of environmental variations spanning about 80 years from 1919 to 1999. It was cut in 744 sub-samples under laminar flow in a clean bench, which were analyzed by Ion Chromatography for major ionic concentration, by a particle counter for insoluble aerosol content, and by Inductively Coupled Plasma Mass Spectrometry (ICP-MS) for the concentration of 45 chemical species from Li to U. This paper focuses on results of trace element concentrations measured by ICP-MS. The high temporal resolution used in the analyses allowed classifying samples as belonging to dry or wet seasons. During wet season elemental concentrations are low and samples show high crustal enrichment factors. During dry seasons the situation is opposite, with high elemental concentrations and low crustal enrichments. For example, with salt lakes as main sources in the region, average Li concentration during the 20th century is 0.035 and 0.90 ng g-1 for wet and dry seasons, respectively. Illimani average seasonal concentration ranges cover the spectrum of elemental concentration measurements at another Andean ice core site (Sajama) for most soil-related elements. Regional crustal dust load in the deposits was found to be overwhelming during dry season, obfuscating the contribution of biomass burning material. Marked temporal trends from the onset of 20th century to more recent years were identified

    This article analyzes the main campaigns run by international agencies and national health bodies to eradicate infectious diseases in rural Latin America in the 1940s and 1950s. The political dimensions of the period have been studied but there has been little attention as yet to the health dimensions. This article proposes the concept of a "culture of survival" to explain the official public health problems of states with limited social policies that did not allow the exercise of citizenship. Public health, as part of this culture of survival, sought a temporary solution without confronting the social problems that led to infections and left a public health legacy in the region.

    Changes in inter-annual variability of summer precipitation over Mexico and Central America are assessed from an ensemble of future climate projections performed with the regional climate model RegCM4. The RCP8.5 greenhouse gas emission scenario of two different Global Climate Models (GCMs) from the Coupled Model Intercomparison Project phase 5 (CMIP5) are used to provide boundary conditions for two different RegCM4 configurations. An intensification and extension of the mid-summer drought is found over Southern Mexico and Central America. Also a delayed onset of the rainy season is found over Northwestern Mexico. An increase in the inter-annual variability of precipitation and temperature is simulated, together with a warming greater than 4 degrees C in the mean seasonal temperature and a drying of more than 20%. A greater warming of the Eastern Pacific Ocean compared to the Tropical North Atlantic Ocean generates a strengthened North Atlantic Subtropical High Pressure and a stronger Caribbean Low Level Jet. This future ENSO-like state appears to be the mechanism driving the changes on the precipitation over the region.

    Prejudice and stigma against people with mental illness can be seen throughout history. The worst instance of this prejudice was connected to the rise of the eugenics movement in the early 20th century. Although the Nazi German T-4 program of killing people with mental illness was the most egregious culmination of this philosophy, the United States has its own dark eugenics history-nearing a slippery slope all too similar to that of the Nazis. Mental health care clinicians need to examine this period to honor the memory of the victims of eugenics and to guarantee that nothing like this will ever happen again.

    Crustal dust in the atmosphere impacts Earth's radiative forcing directly by modifying the radiation budget and affecting cloud nucleation and optical properties, and indirectly through ocean fertilization, which alters carbon sequestration. Increased dust in the atmosphere has been linked to decreased global air temperature in past ice core studies of glacial to interglacial transitions. We present a continuous ice core record of aluminum deposition during recent centuries in the northern Antarctic Peninsula, the most rapidly warming region of the Southern Hemisphere; such a record has not been reported previously. This record shows that aluminosilicate dust deposition more than doubled during the 20th century, coincident with the ≈1°C Southern Hemisphere warming: a pattern in parallel with increasing air temperatures, decreasing relative humidity, and widespread desertification in Patagonia and northern Argentina. These results have far-reaching implications for understanding the forces driving dust generation and impacts of changing dust levels on climate both in the recent past and future. PMID:17389397

    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.

    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.

    Lim, Burton K

    2016-03-01

    Research on mammals in the Guianas of northern South America has had a checkered history. In this review, I summarize the notable contributions to mammalogical study in Guyana, Suriname and French Guiana. These studies began in the mid-18th century with the binomial nomenclature system of scientific classification created by the Swedish naturalist Carl Linnaeus, who described 23 species new to science based on holotype specimens from the Guianas. Notwithstanding popular accounts by amateur naturalists visiting this region, over the next 7 decades there was only sporadic taxonomic work done on Guianan mammals primarily by researchers at European museums. The first comprehensive biological exploration took place in the 1840s during a geographic survey of the boundaries of British Guiana. However, it was not until almost half a century later that scientific publications began to regularly document the increasing species diversity in the region, including the prodigious work of Oldfield Thomas at the British Museum of Natural History in London. Another lull in the study of mammals occurred in the mid-1910s to the early 1960s after which foreign researchers began to rediscover the Guianas and their pristine habitats. This biological renaissance is still ongoing and I give a prospectus on the direction of future research in one of the last frontiers of tropical rainforest. An initiative that would be greatly beneficial is the establishment of a university network in the Guianas with graduate-based research to develop a cadre of professional experts on biodiversity and evolution as seen in other countries of South America.

    The aim of this study is to assess the impact of land-use and land-cover change (LULCC) on regional climate projections for North America. To this end, two transient climate change simulations, with and without LULCC, but identical atmospheric forcing, are performed with the 5th generation of the Canadian Regional Climate Model (CRCM5) driven by CanESM2 model for the (2006-2100)-RCP4.5 scenario. For the simulation with LULCC, land-cover data sets are taken from the Global Change Assessment Model representing the RCP4.5 scenario for the period 2006-2100. LULCC in RCP4.5 scenario point to significant reduction in cultivated land (e.g. Canadian Prairies and Mississippi basin) due to intense afforestation. Results suggest that biogeophysical effects of LULCC on climate, assessed through differences between the all-forcing (atmospheric and LULCC) run and the atmospheric forcing run (with constant land cover) are substantial for relevant surface variables. It is shown that the afforestation of cropland lead to warmer regional climates, especially in winter (warming above 1.5 °C), as compared with climates resulting from atmospheric forcings alone. The investigation of processes leading to this response shows high sensitivity of the results to changes in albedo as a response to LULCC. Additional roughness, evaporative cooling and water soil availability also seem to play an important role in regional climate especially for the summer season in certain afforested areas (e.g., southeastern US).

    2016-01-01

    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. PMID:26697870

    1979-01-01

    This piece describes abortion practices in use from the 1600s to the 19th century among the inhabitants of North America. The abortive techniques of women from different ethnic and racial groups as found in historical literature are revealed. Thus, the point is made that abortion is not simply a "now issue" that effects select women. Instead, it is demonstrated that it is a widespread practice as solidly rooted in our past as it is in the present.

    Funerary practices and bioarchaeological (sex and age) data suggest that a mortality crisis linked to an epidemic episode occurred during the fifth phase of the St. Benedict cemetery in Prague (Czech Republic). To identify this mass mortality episode, we reconstructed individual life histories (dietary and mobility factors), assessed the population's biological homogeneity, and proposed a new chronology through stable isotope analysis (δ(13)C, δ(18)O and δ(15)N) and direct radiocarbon dating. Stable isotope analysis was conducted on the bone and tooth enamel (collagen and carbonate) of 19 individuals from three multiple graves (MG) and 12 individuals from individual graves (IG). The δ(15)N values of collagen and the difference between the δ(13)C values of collagen and bone carbonate could indicate that the IG individuals had a richer protein diet than the MG individuals or different food resources. The human bone and enamel carbonate and δ(18)O values suggest that the majority of individuals from MG and all individuals from IG spent most of their lives outside of the Bohemian region. Variations in δ(18)O values also indicate that all individuals experienced residential mobility during their lives. The stable isotope results, biological (age and sex) data and eight (14)C dates clearly differentiate the MG and IG groups. The present work provides evidence for the reuse of the St. Benedict cemetery to bury soldiers despite the funeral protest ban (1635 AD). The Siege of Prague (1742 AD) by French-Bavarian-Saxon armies is identified as the cause of the St. Benedict mass mortality event.

Astronomers seeking signs of extraterrestrial intelligence have suggested a novel approach: look for alien cities. The search for signs of life in the universe has included the detection of complex organic molecules, seen as a step on the way to living things. But now analysis of spectral signatures known as Unidentified Infrared Emission features found in stars, interstellar space and galaxies suggest that complex organic molecules can be made in stars in a matter of weeks without the presence of life.

  14. Credentialing Kepler: Transits in the Seventeenth Century

    2005-08-01

    Kepler's successful prediction of the 1631 transit of Mercury spurred an interest in his decidedly user-unfriendly Rudolfine Tables. Because his Ephemerides went only to 1636, he did not draw attention to the 1639 transit of Venus, although the tables actually predicted the phenomenon, and the observation by Horrocks again proved the superiority of Kepler's work. By mid-century alternative user-friendly versions of the Rudolfine Tables were published by V. Renieri in Italy, J.B. Morin in France, Maria Cunitia in Germany, and (in a more modified form) by J. Shakerley in England. Transits of Mercury were observed in 1651 (by Shakerley in Surat, India), 1661, 1667, 1690, and 1697, giving astronomers opportunities to compare the predictions from these tables as well as those of Lansbergen (which were a variant of the Copernican Prutenic Tables). Because of the subsequent interest in transits for determining the length of the astronomical unit, the 18th-century French astronomer J-N. Delisle compiled for these early transits extensive systematic records, which are now preserved at the Paris Observatory. By his day, however, the as-yet-unpublished tables of Edmond Halley gave the most successful predictions, and Delisle showed little interest in further credentialing the Rudolfine Tables, a process that had already taken place in the previous century.

    1996-01-01

    The general decline of science which took place in the first half of the 18th century was a cause of a huge quantity of calendars editing. Calendars substituted for the former scientific literature. Up to 1763 over 800 calendars appeared. A half of them was published in Cracov. Those calendars differed from the contemporary ones. Apart from dates, they included not only basic information in history, geography agriculture economy but, not seldom, medicine as well. Most often they were written by university professors with a few physicians among them. Obviously, the level of the presented medical knowledge was very low. There wenadductions to astrology, wizardry and Provinience. But some diagnoses and therapeutic advice being a kind of doctor's manual, useful to so-called domestic medicine are still worth of the attention. First of all, phytotherapy chapter based on the folk empiricism, was the most rational. Thought 18th century calendars did not have much in common with real medicine, they make an interesting source to search for history of the Polish medicine of the Saxon times. PMID:9245110

  16. The Environmental History of Cetaceans in Portugal: Ten Centuries of Whale and Dolphin Records

    2011-01-01

    The history between cetaceans and humans is documented throughout time not only in reports, descriptions, and tales but also in legal documents, laws and regulations, and tithes. This wealth of information comes from the easy spotting and identification of individuals due to their large size, surface breathing, and conspicuous above water behaviour. This work is based on historical sources and accounts accounting for cetacean presence for the period between the 12th and 17th centuries, as well as scientific articles, newspapers, illustrations, maps, non-published scientific reports, and other grey literature from the 18th century onwards. Information on whale use in Portugal's mainland has been found since as early as the 12th century and has continued to be created throughout time. No certainty can be given for medieval and earlier events, but both scavenging of stranded whales or use of captured ones may have happened. There is an increasing number of accounts of sighted, stranded, used, or captured cetaceans throughout centuries which is clearly associated with a growing effort towards the study of these animals. Scientific Latin species denominations only started to be registered from the 18th century onwards, as a consequence of the evolution of natural sciences in Portugal and increasing interest from zoologists. After the 19th century, a larger number of observations were recorded, and from the 20th century to the present day, regular scientific records have been collected. Research on the environmental history of cetaceans in Portugal shows a several-centuries-old exploitation of whales and dolphins, as resources mainly for human consumption, followed in later centuries by descriptions of natural history documenting strandings and at sea encounters. Most cetaceans species currently thought to be present in Portuguese mainland waters were at some point historically recorded. PMID:21931627

    Dengue fever is endemic from Argentina to Mexico, where serotypes 1, 2 and 4 are in wide circulation. After an absence of almost 20 years, serotype 3 arrived in Central America in late 1994. Over the past decade dengue has become a major public health problem in many of these countries, with an increase in the prevalence of dengue haemorrhagic fever and in the number of fatal cases. The situation is not new; there is evidence of a least eight pandemics from the early 19th century until the initiation of the Aedes aegypti eradication campaign in 1947. The resurgence of serious disease was predicted in the early 1980's, and has followed a pattern of increasing severity observed 20 years earlier in Asia.

This fascinating idea started to be taken into consideration as soon as great telescopes permitted to observe and classify numerous and different--shape nebulae, especially spirals, in which novae were discovered. In 1920, a public debate concerning the scale of the universe, took place in Washington: Heber D. Curtis and Harlow Shapley presented their different opinion on this subject. Since that time, a new view of the universe and its dimension started to be considered.

  16. Immigration and the American century.

    PubMed

    Hirschman, Charles

    2005-11-01

    The full impact of immigration on American society is obscured in policy and academic analyses that focus on the short-term problems of immigrant adjustment. With a longer-term perspective, which includes the socioeconomic roles of the children of immigrants, immigration appears as one of the defining characteristics of twentieth-century America. Major waves of immigration create population diversity with new languages and cultures, but over time, while immigrants and their descendants become more "American," the character of American society and culture is transformed. In the early decades of the twentieth century, immigrants and their children were the majority of the workforce in many of the largest industrial cities; in recent decades, the arrival of immigrants and their families has slowed the demographic and economic decline of some American cities. The presence of immigrants probably creates as many jobs for native-born workers as are lost through displacement. Immigrants and their children played an important role in twentieth-century American politics and were influential in the development of American popular culture during the middle decades of the twentieth century. Intermarriage between the descendants of immigrants and old-stock Americans fosters a national identity based on civic participation rather than ancestry.

    The 14th-18th century pandemic of Yersinia pestis caused devastating disease outbreaks in Europe for almost 400 years. The reasons for plague's persistence and abrupt disappearance in Europe are poorly understood, but could have been due to either the presence of now-extinct plague foci in Europe itself, or successive disease introductions from other locations. Here we present five Y. pestis genomes from one of the last European outbreaks of plague, from 1722 in Marseille, France. The lineage identified has not been found in any extant Y. pestis foci sampled to date, and has its ancestry in strains obtained from victims of the 14th century Black Death. These data suggest the existence of a previously uncharacterized historical plague focus that persisted for at least three centuries. We propose that this disease source may have been responsible for the many resurgences of plague in Europe following the Black Death. PMID:26795402

  18. Solar cycle length and 20th Century northern hemisphere warming: Revisited

    NASA Astrophysics Data System (ADS)

    Damon, Paul E.; Peristykh, Alexei N.

    It has been suggested that the length of the solar cycle (SCL) is related to solar forcing of global climate change [Friis-Christensen and Lassen, 1991]. Although no physical mechanism had been proposed, the relation seemed to be supported by interesting correlations with several paleoclimate records and, separately, with the 20th century Northern Hemisphere instrumental record. Actually, what has been correlated is the quasi-sinusoidal Gleissberg cycle which is slightly greater in the 18th century than in the 20th century. Using the pre-industrial record as a boundary condition, the SCL-temperature correlation corresponds to an estimated 25% of global warming to 1980 and 15% to 1997.

  19. Epilepsy and insanity during the early 19th century. A conceptual history.

    PubMed

    Berrios, G E

    1984-09-01

    During the first half of the 19th century, epilepsy and the insanities were considered as closely related "neurotic" disorders. Under the influence of factors such as the decline of the 18th-century Cullean concept of neurosis, the development of the new descriptive psychopathology, the introduction of statistics, and the availability of longitudinal observations of hospitalized cohorts, epilepsy was redefined as a "neurological" disease by the 1850s. The reaction of psychiatry to the exclusion of the mental disorder as a defining feature of epilepsy manifested itself in the creation of the "masked epilepsy" concept. This notion is behind the later development of categories such as "borderland" and "equivalent," which are still of some relevance to 20th-century views of epilepsy.

  20. Pinta: Latin America's Forgotten Disease?

    PubMed

    Stamm, Lola V

    2015-11-01

    Pinta is a neglected, chronic skin disease that was first described in the sixteenth century in Mexico. The World Health Organization lists 15 countries in Latin America where pinta was previously endemic. However, the current prevalence of pinta is unknown due to the lack of surveillance data. The etiological agent of pinta, Treponema carateum, cannot be distinguished morphologically or serologically from the not-yet-cultivable Treponema pallidum subspecies that cause venereal syphilis, yaws, and bejel. Although genomic sequencing has enabled the development of molecular techniques to differentiate the T. pallidum subspecies, comparable information is not available for T. carateum. Because of the influx of migrants and refugees from Latin America, U.S. physicians should consider pinta in the differential diagnosis of skin diseases in children and adolescents who come from areas where pinta was previously endemic and have a positive reaction in serological tests for syphilis. All stages of pinta are treatable with a single intramuscular injection of penicillin. PMID:26304920

    It was in the first half of the 18th century when life sciences started to flourish in the independent republic of Geneva. However, it is difficult to identify a genuine school of developmental biologists during that era. Nevertheless, several prominent scientists over the past two and a half centuries have established and maintained a strong tradition of studies in embryological development and reproduction. In this short historical account, we briefly pay tribute to these famous forerunners, by emphasizing both the originality and quality of their work, as well as the many accompanying conceptual and methodological advances. We start with Abraham Trembley (1710-1784) and the discovery of Hydra and of regeneration, and with Charles Bonnet (1720-1793) who, amongst other contributions, first observed parthenogenetic development. In the 19th century, Carl Vogt (1817-1895) and Edouard Claparède (1832-1871) were well-known scientists in this field of research, whereas Hermann Fol (1845-1892) can be considered as one of the pioneers, if not the founder, of causal embryology, through his experiments on lateral asymmetry in manipulated chicken. More recently, Emile Guyénot (1885-1963) and Kitty Ponse (1897-1982) perpetuated this tradition, which is well alive nowadays in the city of Calvin. PMID:11902688

    People died from nostalgia in the army in the 17th-19th centuries. The term 'nostalgia', created by the doctor Johannes Hofer (1669-1752), from Mulhouse, came from the Germanic Heimweh, or 'homesickness'. It affected the young people enrolled in the army, such as Swiss mercenaries. Longing for their native land, they were consumed by an ongoing desire to return home. If it was impossible to do so, they sank into 'a sadness accompanied with insomnia, anorexia and other unpleasant symptoms' that could lead to death. Nostalgia became classified as a disease during the last quarter of the 18th century and ravaged the French army during the Revolution and the Napoleonic wars. However, as soon as the wars ended, it ceased to exist in the army (except the colonial army). It was removed from the nosology in the first half of the 19th century. Rapidly explained as an example of a misdiagnosis or a confusion between 'connection and cause', nostalgia needs to be assessed in regard to the medical debate between 'alienists' and 'organicists'. Creating much concern, nostalgia needs to be considered in the historical context of a society destabilized by modernity, with some individuals uprooted by the sudden transition from civil society to military life. It raises questions about the role that the army played in the creation of the French national union. Nostalgia may have also covered psychic traumatisms later designated as combat fatigue, war neurosis, or post-traumatic stress disorder.

Assessing the impact of the Conference on attendees' work 6 months post-Conference provides information critical to understanding the impact and the use of new partnerships, knowledge, and skills gained during the Conference. Evaluation assessments, which included collection of quantitative and qualitative data, were administered at two time points: at Conference registration and 6 months post-Conference. The evaluation files were merged using computer IP address, linking responses from each assessment. Percentages of attendees reporting Conference impacts were calculated from quantitative data, and common themes and supporting examples were identified from qualitative data. Online registration was completed by 650 individuals. Of registrants, 30 % responded to the 6 month post-Conference assessment. Between registration and 6 month post-Conference evaluation, the distribution of respondents did not significantly differ by organizational affiliation. In the 6 months following the Conference, 65 % of respondents reported pursuing a networking interaction; 96 % shared knowledge from the Conference with co-workers and others in their agency; and 74 % utilized knowledge from the Conference to translate data into public health action. The Conference produced far-reaching impacts among Conference attendees. The Conference served as a platform for networking, knowledge sharing, and attaining skills that advance the work of attendees, with the potential of impacting organizational and workforce capacity. Increasing capacity could improve MCH programs, policies, and services, ultimately impacting the health of women, infants, and children. PMID:25107597

  7. [The emergence of the Québec asylum in the 19th century.].

    PubMed

    Paradis, A

    1977-01-01

    This team of five philosophers analyses the 18th and 19th century Quebec discourse on the subject of insanity. The 18th century saw the insane excluded from social contact with the state recognizing only their indigence. They were relegated either to the "Loges", designed to expiate their sins since insanity was linked to an abuse of mind and body, or to prison for appropriate punishment, since madness was considered to lead to crime. But economic pressures produced by the growing number in indigents, including the mentally ill, led to the creation of the Beauport asylum in 1845. The authors then describe how the urban insane, marginal to both the French Canadian and English Canadian communities* were placed in private institutions and subjected to a system of profit maximization controlled by bourgeois physicians. This situation increased the distance between proprietors and occupants, and accounts for the lack of original discourse on the subject of insanity. In addition, the reasoning of the alienist physicians was without scientific foundation, taking root rather in the dominant industrial capitalist ideology. As for the content of the discourse, the Beauport physicians borrowed from moral treatment and restraint system notions, giving them a certain Quebec character.

    This chapter documents the fact that "nonmetropolitan America has experienced widespread population gain and net in-migration since 1990. This contrasts with the trend evident through most of this century.... However, this deconcentration has been selective and tempered by economic period effects. Future nonmetropolitan demographic change is likely to be even more dependent on migration because recent rural fertility patterns, together with age structure shifts, have diminished the contribution natural increase can make to rural growth. This increasing dependence on migration, coupled with the greater integration of nonmetropolitan areas into the national and international system, makes rural America increasingly sensitive to national and global economic, political, and social forces."

    Ancient parasites of the genus Tunga originated in America and, during the first half of the 19th century, were transported to the Eastern Hemisphere on transatlantic voyages. Although they were first documented by Spanish chroniclers after the arrival of Columbus, little is known about their presence in pre-Hispanic America. To evaluate the antiquity of tungiasis in America, we assessed several kinds of early documentation, including written evidence and pre-Incan earthenware reproductions. We identified 17 written documents and 4 anthropomorphic figures, of which 3 originated from the Chimu culture and 1 from the Maranga culture. Tungiasis has been endemic to Peru for at least 14 centuries. We also identified a pottery fragment during this study. This fragment is the fourth representation of tungiasis in pre-Hispanic America identified and provides explicit evidence of disease endemicity in ancient Peru. PMID:21529395

    2008-01-01

    Glaciers cover about 75,000 km2 of Alaska, about 5 percent of the State. The glaciers are situated on 11 mountain ranges, 1 large island, an island chain, and 1 archipelago and range in elevation from more than 6,000 m to below sea level. Alaska's glaciers extend geographically from the far southeast at lat 55 deg 19'N., long 130 deg 05'W., about 100 kilometers east of Ketchikan, to the far southwest at Kiska Island at lat 52 deg 05'N., long 177 deg 35'E., in the Aleutian Islands, and as far north as lat 69 deg 20'N., long 143 deg 45'W., in the Brooks Range. During the 'Little Ice Age', Alaska's glaciers expanded significantly. The total area and volume of glaciers in Alaska continue to decrease, as they have been doing since the 18th century. Of the 153 1:250,000-scale topographic maps that cover the State of Alaska, 63 sheets show glaciers. Although the number of extant glaciers has never been systematically counted and is thus unknown, the total probably is greater than 100,000. Only about 600 glaciers (about 1 percent) have been officially named by the U.S. Board on Geographic Names (BGN). There are about 60 active and former tidewater glaciers in Alaska. Within the glacierized mountain ranges of southeastern Alaska and western Canada, 205 glaciers (75 percent in Alaska) have a history of surging. In the same region, at least 53 present and 7 former large ice-dammed lakes have produced jokulhlaups (glacier-outburst floods). Ice-capped volcanoes on mainland Alaska and in the Aleutian Islands have a potential for jokulhlaups caused by subglacier volcanic and geothermal activity. Because of the size of the area covered by glaciers and the lack of large-scale maps of the glacierized areas, satellite imagery and other satellite remote-sensing data are the only practical means of monitoring regional changes in the area and volume of Alaska's glaciers in response to short- and long-term changes in the maritime and continental climates of the State.

    This overview reflects the extensive changes in the health care system which had significant effects on the apothecaryâs profession and education. In the 18(th) 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 apothecaryâs 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 19(th) century also affected the apothecary business and led to a crisis of the profession. Furthermore, the apothecariesâ 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

    Stroke is one of the leading causes of mortality in Latin America, with variable incidence and prevalence throughout the continent reflecting regional socioeconomic differences. In Latin America, uncontrolled hypertension is one of the major causes of stroke, but other modifiable risk factors also play a role, such as heavy alcohol consumption and smoking. Intracerebral hemorrhage and lacunar stroke are more frequent in Latin America than in North America and Europe. There are multiple causes of stroke that are endemic to Latin America, including neurocysticercosis, Chagas' disease, sickle cell anemia, malaria, hemorrhagic fever, and snake bites.

    Anthrax has been described as a veterinary disease of minor importance to clinical medicine, causing occasional occupational infections in single cases or clusters. Its potential for rapid and widespread epidemic transmission under natural circumstances has not been widely appreciated. A little-known 1770 epidemic that killed 15,000 people in Saint-Domingue (modern Haiti) was probably intestinal anthrax. The epidemic spread rapidly throughout the colony in association with consumption of uncooked beef. Large-scale, highly fatal epidemics of anthrax may occur under unusual but natural circumstances. Historical information may not only provide important clues about epidemic development but may also raise awareness about bioterrorism potential. PMID:12396933

In the William Freeman trial, nine physicians testified that the murderer was insane while eight said he was sane. Juries convicted both prisoners; one was hanged and the other died in prison awaiting a new trial. Seward's legal defense attracted much attention to the jurisprudence of insanity and to insanity in general.

    The United States has sunk to 10th place worldwide in broadband deployment, and the current and foreseeable bandwidth offerings of the major American telephone and cable providers are woefully inadequate to support the nation's future bandwidth needs. A century ago, when the private power companies focused on electrifying large population centers and left most of the nation literally in the dark, thousands of communities formed their own electric utilities and thrived, while others that did not became 'ghost towns.' Several major cities also formed municipal electric utilities that cut power prices in half while significantly improving service quality. Jim Baller, a national leader in the community broadband movement, will discuss the role that local governments, educational institutions, the scientific community, and others can play today to help America break through its bandwidth bottleneck.

  3. Consequences of land use and climate changes on sediment deposition in estuaries during the last centuries

    Estuaries are the downstream end-member of fluvial systems. They are experiencing high sedimentation rates, thus providing good opportunities for high resolution studies of Holocene environmental changes at the land/ocean interface. From a thorough literature survey, it appears that a rapid siltation and/or an increase in sedimentation rate were recorded in many estuarine environments, concomitantly to major migrations of human population throughout the world, both in time and space. It has been clearly related to an increase in sediment supply to estuaries in Minor Asia (Bronze Age, e.g. Spezzaferri et al, 2000) and in North America and Southwest Pacific (18th and 19th centuries, e.g. Goff, 1997), in response to deforestation on catchment areas. However, this relationship is less obvious in Europe (Sorrel et al., 2009), because deforestation occurred concomitantly to climate changes of the last millennium (climate instability at the end of Medieval Warm Period, Little Ice Age) that can also explain an increase in soil erosion. Indeed, these hypotheses have been proposed to explain a similar change in Marennes-Oléron Bay (Atlantic coast of France), which consists in the sudden deposition of a few meters-thick mud drape on basal mixed mud and sand bodies (Billeaud et al., 2005). The methods used to investigate this estuarine bay so far (very high resolution seismic stratigraphy, grain size analysis and radiocarbon dating) provided relevant information about recent environmental changes, but new data are now needed for further investigation. In the present study, we provide a multi-proxy analysis of the Marennes-Oléron Bay mud drape. A new 8 m-long core (M7UC01) was sampled on an intertidal flat, its location being determined on the basis of seismic stratigraphy. Core processing included visual description, physical measurements, grain size analysis every 2.5 to 5 cm, AMS radiocarbon dating, XRF core scanning, clay mineralogy and Rock Eval analysis.

    This paper shows how the community of Latin-American and Spanish psychiatry represents a solid platform for the so-called 'continental thought' to meet the analytical Anglo-Saxon thought. It reviews what both Latin America and the Spanish and Portuguese languages represent in the American continent; the relation between Spanish psychiatry and Spanish-speaking psychiatry in America during the twentieth century; the reality of psychiatric research and profession in Latin America; the evolution of Spanish psychiatry in the twentieth century from the post civil war diaspora to the beginning of the twenty-first century, and research on mental health in Spain and the foreseeable future.

    The freshwater and marine fish faunas of South America are the most diverse on Earth, with current species richness estimates standing above 9100 species. In addition, over the last decade at least 100 species were described every year. There are currently about 5160 freshwater fish species, and the estimate for the freshwater fish fauna alone points to a final diversity between 8000 and 9000 species. South America also has c. 4000 species of marine fishes. The mega-diverse fish faunas of South America evolved over a period of >100 million years, with most lineages tracing origins to Gondwana and the adjacent Tethys Sea. This high diversity was in part maintained by escaping the mass extinctions and biotic turnovers associated with Cenozoic climate cooling, the formation of boreal and temperate zones at high latitudes and aridification in many places at equatorial latitudes. The fresh waters of the continent are divided into 13 basin complexes, large basins consolidated as a single unit plus historically connected adjacent coastal drainages, and smaller coastal basins grouped together on the basis of biogeographic criteria. Species diversity, endemism, noteworthy groups and state of knowledge of each basin complex are described. Marine habitats around South America, both coastal and oceanic, are also described in terms of fish diversity, endemism and state of knowledge. Because of extensive land use changes, hydroelectric damming, water divergence for irrigation, urbanization, sedimentation and overfishing 4-10% of all fish species in South America face some degree of extinction risk, mainly due to habitat loss and degradation. These figures suggest that the conservation status of South American freshwater fish faunas is better than in most other regions of the world, but the marine fishes are as threatened as elsewhere.

    The present century has been a disappointing one for comets, but past centuries often featured spectacular, unforgettable comet shows that dominated the night (and even daytime) sky for months: comets that outshone Venus or even the Moon, whose spectacular tails stretched more than halfway across the sky or were weirdly split, and whose apparition was held responsible for everything from wars to unusually good wine vintages. Published to coincide with the first naked-eye appearance of Comet Hale-Bopp, perhaps our own comet of the century, this book is an irresistible guide to comet facts and lore throughout history.

  17. Education, democracy and development in Latin America

    NASA Astrophysics Data System (ADS)

    Gomes, Candido

    1993-11-01

    The education first brought to America by Europeans was hardly more than ornamental culture, literacy was generally unimportant, and African slaves were not educated at all. Only in this century did industrialization cause some governments to provide economic and technological support through training and education. In the last decade, the debt crisis curtailed spending, while numbers of students and teachers continued to rise. A comparison between Latin America and South Korea illustrates the former's relative decline in investment. The advent of populist and corporatist democracies did not alleviate the situation, although there is now some evidence of concern for basic education for poorer children. With economic adjustment programmes, little else has been done for those who have suffered the heaviest burdens, and no obvious solutions to poverty and technological obsolescence are in prospect. A major reform of State institutions is called for, including a commitment to education, a change in the economic model, and a recognition of global interdependence.

    Our shared heritage of some 3 million photographic observations is seriously in jeopardy, and astronomy may well lose vital, unrepeatable data dating back over a century. A call for preservation of astronomical plates has been made by the international astronomical community. This project is in response, and aims to establish a national archive for astronomical plates at the Pisgah Astronomical Research Institute that will preserve and eventually digitize selections of the plate collections in North America. Our poster describes details of the storage, cleaning and cataloging procedures that have been planned, and provides an overview of what is anticipated for succeeding Phases.

    1992-06-01

    Considerable scholarly debate has focused on the nature of demographic change in the Americas before and after 1492. Recent research on human skeletal samples and related archeological materials suggests that morbidity and mortality were increasing throughout much of the Western Hemisphere before 1492 in response to increased population density, increased sedentism, and changing subsistence. The evidence suggests that after 1492 population reduction was caused not by continental pandemics but by localized or regional epidemics augmented by social and economic disruption. The twentieth century has witnessed remarkable Native American population recovery, fueled both by improvements in health care and changing definitions of "being Indian."

  1. What was Glaucoma Called Before the 20th Century?

    PubMed Central

    Leffler, Christopher T.; Schwartz, Stephen G.; Giliberti, Francesca M.; Young, Matthew T.; Bermudez, Dennis

    2015-01-01

    Glaucoma involves a characteristic optic neuropathy, often with elevated intraocular pressure. Before 1850, poor vision with a normal eye appearance, as occurs in primary open-angle glaucoma, was termed amaurosis, gutta serena, or black cataract. Few observers noted palpable hardness of the eye in amaurosis. On the other hand, angle-closure glaucoma can produce a green or gray pupil, and therefore was called, variously, glaucoma (derived from the Greek for glaucous, a nonspecific term connoting blue, green, or light gray) and viriditate oculi. Angle closure, with palpable hardness of the eye, mydriasis, and anterior prominence of the lens, was described in greater detail in the 18th and 19th centuries. The introduction of the ophthalmoscope in 1850 permitted the visualization of the excavated optic neuropathy in eyes with a normal or with a dilated greenish-gray pupil. Physicians developed a better appreciation of the role of intraocular pressure in both conditions, which became subsumed under the rubric “glaucoma”. PMID:26483611

    1987-01-01

    This study is a history of early principles and practices of music therapy in the United States. The evidence suggests that the public press introduced the idea of using music as an adjunct to medicine in the late 18th century. This was followed by scholarly tracts written by medical students at the University of Pennsylvania in support of music therapy. The era concluded with implementation of organized musical activities in institutions for visually-handicapped and hearing-impaired students and renewed advocacy of music therapy. Primary sources for the study include articles and dissertations from the era and contemporaneous accounts and reports. The study concludes that music therapy grew at a slow but steady pace and that the profession developed on an apparently secure foundation. PMID:10301541

  6. Hydrological climate change projections for Central America

    2013-07-01

    Runoff climate change projections for the 21st century were calculated from a suite of 30 General Circulation Model (GCM) simulations for the A1B emission scenario in a 0.5° × 0.5° grid over Central America. The GCM data were downscaled using a version of the Bias Correction and Spatial Downscaling (BCSD) method and then used in the Variable Infiltration Capacity (VIC) macroscale hydrological model. The VIC model showed calibration skill in Honduras, Nicaragua, Costa Rica and Panama, but the results for some of the northern countries (Guatemala, El Salvador and Belize) and for the Caribbean coast of Central America was not satisfactory. Bias correction showed to remove effectively the biases in the GCMs. Results of the projected climate in the 2050-2099 period showed median significant reductions in precipitation (as much as 5-10%) and runoff (as much as 10-30%) in northern Central America. Therefore in this sub-region the prevalence of severe drought may increase significantly in the future under this emissions scenario. Northern Central America could warm as much as 3 °C during 2050-2099 and southern Central America could reach increases as much as 4 °C during the same period. The projected dry pattern over Central America is consistent with a southward displacement of the Intertropical Convergence Zone (ITCZ). In addition, downscaling of the NCEP/NCAR Reanalysis data from 1948 to 2012 and posterior run in VIC, for two locations in the northern and southern sub-regions of Central America, suggested that the annual runoff has been decreasing since ca. 1980, which is consistent with the sign of the runoff changes of the GCM projections. However, the Reanalysis 1980-2012 drying trends are generally much stronger than the corresponding GCM trends. Among the possible reasons for that discrepancy are model deficiencies, amplification of the trends due to constructive interference with natural modes of variability in the Reanalysis data, errors in the Reanalysis

  7. Deaths in childbed from the eighteenth century to 1935.

    PubMed

    Loudon, I

    1986-01-01

    The history of maternal deaths in England from the earliest records in the 1700s to 1935, concentrating on the influence of medical practice, is recounted. The rate lay between 4 and 5 per 1000 until 1935, with the advent of sulfa antibiotics to prevent puerperal infections. The practice of midwifery by men began in the early 17th century in Britain, but attendance at normal labors by medical practitioners, that is, surgeon-apothecaries, did not become common, and then only in urban areas, until 1730. The use of forceps became widely known about that time, and lying-in hospitals were begun. Obstetrics was held in contempt by professionally educated and registered physicians and apothecaries, however, because of the immodesty and messiness of the work and the long hours involved. Estimates of maternal mortality, from the 1st recorded unselected series, in the late 18th century range from 5-29/1000. Some of the high figures are from specialists in obstetrics, who treated complicated cases. From these data the maternal death rate was estimated at about 25/1000 among unassisted women. Some institutions achieved results better than the national average in the 1920s, suggesting that by the end of the 18th century, a fairly good understanding of childbirth had been reached. At that time the overall forceps rate was conservative, less than 1% compared to 15% now. Use of the perforator, hook and crochet, and manual dilatation of the cervix had been abandoned. In the 19th century, lying-in hospitals became more common and their death rates were higher, probably due to less conservative methods, up to as high as 85/1000, until the advent of antisepsis in 1880. Nevertheless, hospital births were the minority, amounting to 15% in 1927, 54% in 1946, 87% in 1970, 98.8% in 1980. Sepsis, due to casual use of sterile technique, remained the cause of half the total deaths until 1937. It is difficult to assess the contribution of toxemia or obstructed labor in maternal deaths.

    During the last century, historians have discovered that between the 13th and 18th centuries, at least six sages discovered that the air we breathe contains something that we need and use. Ibn al-Nafis (1213-1288) in Cairo and Michael Servetus (1511-1553) in France accurately described the pulmonary circulation and its effect on blood color. Michael Sendivogius (1566-1636) in Poland called a part of air "the food of life" and identified it as the gas made by heating saltpetre. John Mayow (1641-1679) in Oxford found that one-fifth of air was a special gas he called "spiritus nitro aereus." Carl Wilhelm Scheele (1742-1786) in Uppsala generated a gas he named "fire air" by heating several metal calcs. He asked Lavoisier how it fit the phlogiston theory. Lavoisier never answered. In 1744, Joseph Priestley (1733-1804) in England discovered how to make part of air by heating red calc of mercury. He found it brightened a flame and supported life in a mouse in a sealed bottle. He called it "dephlogisticated air." He published and personally told Lavoisier and other chemists about it. Lavoisier never thanked him. After 9 years of generating and studying its chemistry, he couldn't understand whether it was a new element. He still named it "principe oxigene." He was still not able to disprove phlogiston. Henry Cavendish (1731-1810) made an inflammable gas in 1766. He and Priestley noted that its flame made a dew. Cavendish proved the dew was pure water and published this in 1778, but all scientists called it impossible to make water, an element. In 1783, on June 24th, Lavoisier was urged to try it, and, when water appeared, he realized that water was not an element but a compound of two gases, proving that oxygen was an element. He then demolished phlogiston and began the new chemistry revolution.

    The 14th–18th century pandemic of Yersinia pestis caused devastating disease outbreaks in Europe for almost 400 years. The reasons for plague’s persistence and abrupt disappearance in Europe are poorly understood, but could have been due to either the presence of now-extinct plague foci in Europe itself, or successive disease introductions from other locations. Here we present five Y. pestis genomes from one of the last European outbreaks of plague, from 1722 in Marseille, France. The lineage identified has not been found in any extant Y. pestis foci sampled to date, and has its ancestry in strains obtained from victims of the 14th century Black Death. These data suggest the existence of a previously uncharacterized historical plague focus that persisted for at least three centuries. We propose that this disease source may have been responsible for the many resurgences of plague in Europe following the Black Death. DOI: http://dx.doi.org/10.7554/eLife.12994.001 PMID:26795402

    2005-12-01

    In the late 8th century, the stage for Viking expansion was set by commercial expansion in northwest Europe, the pressure of an increasing population in limited territorial reserves, and the development of the Viking ships. The Norsemen traveled extensively over the oceans, south to the Holy Land, and north to the White Sea and settled over a wide area from Sicily to Greenland. Historical sources, including the reports by Adam of Bremen and the Icelandic Sagas, describe several expeditions from Greenland to Vinland (somewhere along the east coast of North America) in approximately AD 1000 and later. Historians have arrived at highly different conclusions with respect to the location of Vinland (from Labrador to Georgia), but, in 1960, the Norwegian explorer Helge Ingstad localized ancient house sites on L'Ans aux Meadows, a small fishing village on the Northern beaches of Newfoundland. From 1961 to 1969, Ingstad and his wife, Anne Stine (an archaeologist), led several archaeological expeditions that revealed Viking turf houses with room for approximately 100 people. They also excavated a smithy, outdoor cooking pits, boathouses, a bathhouse, and enclosures for cattle, in addition to several Viking artifacts. The finds were C dated to AD 990 +/- 30. The present report reviews historical and archaeological evidence indicating the sites to which the Vikings traveled and attempted to settle in the new world.

    By the end of the 19th century, exfoliated cancer cells had been described in all of the types of specimen in which we find them today. However, it was not until Drs. Papanicolaou and Traut published their account of the diagnosis of uterine cancer from exfoliated cells (1941 and 1943) that cytopathology acquired the momentum to develop into the powerful presence that it has in human medicine today. These and the subsequent publications by Papanicolaou stimulated the development and application of cytopathology worldwide, resulting in abundant literature on the subject and a galaxy of outstanding practitioners. The 1980s saw the development and widespread use of aspiration cytology. This was followed in the 1990s by the development of automated screening systems, marking the latest stage in the evolution of cytopathology. These and other events and achievements in cytopathology, from its meager beginnings in the early 20th century to its worldwide use and acceptance today, mark this century as the "century for cytopathology."

    Global warming is expected to increase the frequency and intensity of droughts in the twenty-first century, but the relative contributions from changes in moisture supply (precipitation) versus evaporative demand (potential evapotranspiration; PET) have not been comprehensively assessed. Using output from a suite of general circulation model (GCM) simulations from phase 5 of the Coupled Model Intercomparison Project, projected twentyfirst century drying and wetting trends are investigated using two offline indices of surface moisture balance: the Palmer Drought Severity Index (PDSI) and the Standardized Precipitation Evapotranspiration Index (SPEI). PDSI and SPEI projections using precipitation and Penman- Monteith based PET changes from the GCMs generally agree, showing robust cross-model drying in western North America, Central America, the Mediterranean, southern Africa, and the Amazon and robust wetting occurring in the Northern Hemisphere high latitudes and east Africa (PDSI only). The SPEI is more sensitive to PET changes than the PDSI, especially in arid regions such as the Sahara and Middle East. Regional drying and wetting patterns largely mirror the spatially heterogeneous response of precipitation in the models, although drying in the PDSI and SPEI calculations extends beyond the regions of reduced precipitation. This expansion of drying areas is attributed to globally widespread increases in PET, caused by increases in surface net radiation and the vapor pressure deficit. Increased PET not only intensifies drying in areas where precipitation is already reduced, it also drives areas into drought that would otherwise experience little drying or even wetting from precipitation trends alone. This PET amplification effect is largest in the Northern Hemisphere mid-latitudes, and is especially pronounced in western North America, Europe, and southeast China. Compared to PDSI projections using precipitation changes only, the projections incorporating both

    Important environmental changes that have become increasingly pronounced in the last two centuries and that are seriously affecting human health require the development of integrated and participatory scientific approaches that can result in proposals for institutional and public policy changes. The purpose of this article is to offer some elements that can contribute to a line of reflection based on studies with ecosystem approaches in the Latin America context. The authors begin with a brief description of current scientific literature in public health that links ecosystems and human health in Latin America; next, they describe and compare the two prevailing trends that form the basis for the theoretical and methodological debates on ecosystem approaches; they also review the empirical research in Latin America or concerning Latin American countries in which an ecosystem approach has been adopted. The results point to limited scientific output on the interface between ecosystems and human health; aspects involving public participation and implementation of institutional changes and public policies are still in a rather incipient stage.

    Before the advent of diagnostic criteria for multiple sclerosis (MS), it was reported that the prevalence of MS in Mexico was "one of the lowest in the world" (1.6/100,000).(1) The notion that MS was a rare neurologic disease among those living in the tropics of the Americas and Southern latitudes was widely accepted. The geopolitical boundaries of the region identified as Latin America (LA) extend from the southern border of United States with Mexico (32° North latitude) to the Argentinian and Chilean Patagonia in South America (56° South latitude). The largest Spanish-speaking island countries in the Caribbean-Cuba, Dominican Republic, and Puerto Rico-are also traditionally considered part of LA. The continental mass includes 17 countries with a population of more than 550 million. Due to centuries of racial intermixing, it is a heterogeneous and genetically complex population. The blended cultures of native Amerindians with white Caucasian Europeans and black Africans has resulted in the predominant ethnic Latin American Mestizo. The influence of African genetics is notable in many areas of the subcontinent and the Caribbean. A common observation across LA is the absence of identification of MS in non-mixed Amerindians(2); the reason for this phenomenon is unclear.

The resolution of the record (0.3-0.7 mm/sample) permits identification of the dominant drivers of stalagmite 14C during different intervals. For example, hydrologic control on 14C appears dominant during the 11th century drought, while in the 16th to 18th century a clear solar influence exists. Solar activity is reflected in YOK-I as lower a14Cinit, reflecting the atmospheric a14C. We apply simple hydrological models to investigate the different factors influencing 14C in YOK-I. We estimate the importance of mean SOM age to signal dampening, and quantify the strength of the solar influence and the global carbon cycle on the record.

    1998-12-31

    Seventeen years ago John E. Carroll and Newell B. Mack analyzed the then-current status of environmental protection mechanisms used between Canada and the United States. They criticized the ad hoc nature of North America`s history of environmental dispute resolution, which they dubbed ``ad hockery,`` and believed the present ambiguity hurt business, diplomatic relations, and the citizenry`s environment. Since that publication, increasing efforts to incorporate environmental concerns into Conventions have resulted in several multilateral agreements focusing on environmental protection and dispute resolution. Part 2 of this paper introduces a few of these recent agreements and the mechanisms they have established to monitor environmental damage and to enforce the goals of the agreements. The agreements discussed include: Montreal Protocol on Substances that Deplete the Ozone Layer; Vienna Convention for the Protection of the Ozone Layer; Protocol on Substances that Deplete the Ozone Layer; Basel Convention on the Control of Transboundary Movements of Hazardous Wastes and their Disposal; Canada-United States: Agreement on Air Quality; Rio Declaration on Environment and Development; Framework Convention on Climate Change; Convention on Biological Diversity; and the North American Agreement on Environmental Cooperation. Part 3 discusses the general concern related to economic development (with the need to maintain ``sustainable development``), the possible environmental impact of NAFTA, and the Supplemental Agreement`s strengths and weaknesses.

    This work gathers reports about Neospora-infections in South America. Neospora-infections have been reported from Argentina, Brazil, Chile, Paraguay, Peru and Uruguay. Evidence of exposure to N. caninum was mentioned in cattle, goats, sheep, dogs, cats, water buffaloes, alpacas, llamas, South American opossums, wolves and other wild canids. No antibodies were found in horses. Interesting epidemiological and pathological data were described. Two isolations were performed from dogs, one from cattle, and recently five from water buffaloes. Since the cattle industry is important in South America and reproductive losses caused by Neospora-infection have been identified, more investigations are needed in order to understand its epidemiology and control the disease.

    Schillinger, Klaus

    In 1777, J. G. Köhler, an academician trained in mathematics and the sciences and with a deep interest in astronomy, was appointed inspector of the Mathematical-Physical Salon. He was lucky to find, in the person of the Saxonian electoral prince and later king, August the Righteous, a ruler who was open-minded to science, and thus he could combine his private interests with those of the sovereign. While the files of the Mathematical-Physical Salon from his time were lost during World War II, his actions can be reconstructed from a few archival sources and notes in the diaries of his successors. The Saxonian residence did not have an astronomical observatory. Köhler used the instruments from the collection of the Mathematical-Physical Salon for numerous celestial observations. He was in close contact with a number of other astronomers like Bode and Zach. They took care of his results, sometimes after editing them. Time determinations based on longitude and latitude determinations, as well as other astronomical observations, led to the development of a time service, which was carried out for about 150 years. Köhler himself constructed the clocks. Because of his responsibilities as an inspector, as well as due to local and material constraints, he was not able to carry out systematic and reproducible measurements over a long time span. His improvement of the circular micrometer and his stop-down photometer are of special interest. He also had considerable talent in drawing, as is shown in his drawings of lunar mountains. A number of instruments used by Köhler are still to be found in the Mathematical-Physical Salon.

    The contributions of this volume are dedicated to Gottfried Kirch (1639-1710), the first Berlin astronomer, on the occasion of the 300th anniversary of his death. They deal with the astronomy of his times and developments in later times, which are connected to his work. The papers deal with the following topics: The instrumental equipment of Berlin Observatory at the time of G. Kirch and its modernisation up to around 1780; the instruments of Johann Makob Marioni's Viennese observatory around 1730; the heraldic celestial globe by Kirch's teacher Erhard Weigel. In addition, they deal with Kirch's share in the propagation of ideas of the Enlightenment, and with the Berlin meteorological record and its consequences for the investigation of anthropogenous climatic changes. They also deal with astronomical topics in the exchange of letters between Leonhard Euler and Daniel Bernoulli, and with the Berlin "Astronomisches Jahrbuch", which is based on Kirch's activities, as a biographical source.

    Hybridization with introduced genetic resources is commonly practiced in ornamental plant breeding to introgress desired traits. The 19th century was a golden age for rose breeding in France. The objective here was to study the evolution of rose genetic diversity over this period, which included the introduction of Asian genotypes into Europe. A large sample of 1228 garden roses encompassing the conserved diversity cultivated during the 18th and 19th centuries was genotyped with 32 microsatellite primer pairs. Its genetic diversity and structure were clarified. Wide diversity structured in 16 genetic groups was observed. Genetic differentiation was detected between ancient European and Asian accessions, and a temporal shift from a European to an Asian genetic background was observed in cultivated European hybrids during the 19th century. Frequent crosses with Asian roses throughout the 19th century and/or selection for Asiatic traits may have induced this shift. In addition, the consistency of the results with respect to a horticultural classification is discussed. Some horticultural groups, defined according to phenotype and/or knowledge of their pedigree, seem to be genetically more consistent than others, highlighting the difficulty of classifying cultivated plants. Therefore, the horticultural classification is probably more appropriate for commercial purposes rather than genetic relatedness, especially to define preservation and breeding strategies.

    2011-12-01

    Over the last half century, Louisiana's coastal wetlands have evolved into an elaborate energy landscape that supports onshore and offshore oil and gas development. Since the 1950s, this region has become a vital part of America's energy security and economic prosperity. Today, roughly one quarter of America's oil and gas resources flow through this energy corridor. The environmental changes as a result of these activities have been substantial, as the vast network of pipeline canals and related infrastructure have radically altered these wetlands. This work explores the intersection between energy and environment in coastal Louisiana and offers a historical view of how this energy system and this environment system evolved together to form America's Energy Corridor.

It maps the routes used to transport the plants from Spanish America to Europe and, along the arteries of European commerce, colonialism and proselytism, into societies across the Americas, Asia and Africa. Inquiring into the causes of the global 'spread' of American remedies, it argues that medicinal plants like ipecacuanha, guaiacum, sarsaparilla, jalap root and cinchona moved with relative ease into Parisian medicine chests, Moroccan court pharmacies and Manila dispensaries alike, because of their 'exotic' charisma, the force of centuries-old medical habits, and the increasingly measurable effectiveness of many of these plants by the late eighteenth century. Ultimately and primarily, however, it was because the disease environments of these widely separated places, their medical systems and materia medica had long become entangled by the eighteenth century.

    2010-06-01

    This article discusses three aspects of the history of astrology in seventeenth-century Peru that are of larger interest for the history of science in Latin America: Creole concerns about indigenous idolatry, the impact of the Inquisition on natural philosophy, and communication between scholars within the Spanish colonies and the transatlantic world. Drawing mainly on the scholars Antonio de la Calancha, Juan de Figueroa, and Ruiz de Lozano, along with several Jesuits, the article analyzes how natural and medical astrology took shape in Peru and how they fostered astronomical investigations of the southern skies. While natural and medical astrology, showing New and Old World influences, oscillated between orthodoxy and heterodoxy, and between scholasticism and new science, judicial astrology remained undeveloped. Toward the end of the seventeenth century the discourse about astrology took an unexpected turn, reflecting a newly invigorated moral and Christian reading of the heavens that was in part a response to a deep-rooted dissatisfaction with the failure of the extirpation of idolatry campaigns. Inscribing divine and cardinal virtues, the Virgin Mary, Christian saints, and Greco-Roman allegories into the heavens was considered a way to finally solve the problem of idolatry and to convey Creole greatness.

  12. [From spermatic animalcules to sperm cells: the reconceptualization of generation in the 19th century].

    PubMed

    Vienne, Florence

    2009-09-01

    At the end of the 18th and still at the beginning of the 19th century most naturalists considered spermatic animalcules to be parasites of the seminal fluid that played no role in procreation. This view was progressively questioned by 19th century physiologists. They gradually redefined the spermatic animals as (cellular) products of the male organism, as agents of fertilization and bearers of the male heredity material. This article discusses this change from two different perspectives: on a microhistorical level, it analyzes the experimental research of the naturalist Lazzaro Spallanzani (1729-1799) and of the physiologist Albert Kölliker (1817-1905) in order to show how spermatozoa were turned into a new epistemic object of biology--the sperm cell. Further, it asks how the role of the reconceptualization of spermatic animalcules affected the long-term transformations that gave rise of our modern understanding of heredity, generation and the sexed body. By combining these two perspectives, the article aims to connect historiographies that are often kept separate: the macrohistorical narratives about gender and the body in the modern age and the microhistorical studies of biomedical practices and objects.

  13. On the development of German beating-reed organ pipes during the 19th century

    NASA Astrophysics Data System (ADS)

    Braasch, Jonas

    2001-05-01

    In the 19th century organ literature, it is often claimed that German organ builders generally adapted the way of building their beating-reed pipes after being influenced by new developments from England and France. To investigate whether this hypothesis is true or false, the reed-pipe sounds of several German historic organs and an English organ by Henry Willis were measured and analyzed. The outcome of the analysis, however, cannot confirm the given hypothesis. Organ builders of the 18th century, such as Gottfried Silbermann for example, were already able to build beating-reed pipes similar in sound to the pipes that are used nowadays in Germany. It is noteworthy that Silbermann used closed shallots in some of his stops, although they are thought to be one of the main inventions in the English and French organ reforms. The use of higher wind pressures, which is also a main part of this reform, on the other hand, never became a common standard in Germany, as was the case for France and Great Britain.

  15. a GIS of SARDINIA'S Coastal Defense System (xvi - XVIII Century)

    NASA Astrophysics Data System (ADS)

    Deidda, M.; Musa, C.; Vacca, G.

    2015-06-01

    The use of GIS as a tool for archival, analysis and representation of geographic information has become significantly popular in many scientific fields that are directly concerned with the "territory" as their object of study. The field of application of GIS, however, has expanded also in other areas, such as those related to humanities and architecture, in which the territory is studied in an "indirect" mode because it constitutes a kind of substrate on which to develop a specific spatial analysis for particular purposes. Among these areas are to be included certainly archeology and restoration, fields in which the GIS has become a useful tool for historical studies. In this work we present a GIS developed for the study of the historical and territorial coastal defense system of Sardinia (16th - 18th century), in order to respond to the need to store, analyze and efficiently manage the information regarding cultural heritage and landscape heritage such as that consisting of the coastal defensive towers of Sardinia. This defensive system, in fact, was composed by over 100 towers positioned around the entire coastal perimeter of Sardinia, of which more than 90 still exist today. Their position was planned on the basis of the following criteria: - Warning the neighboring towers about the sighting of enemy ships - Protecting coasts located near the towns - Monitoring the water sources near the coast - Allowing for the full visibility of the coasts of any morphology With this study we also verified, through the use of high resolution and high accuracy DTM (LiDAR) and the topographic databases, whether the positioning criteria specified in the design of the system were respected and effective.

    Consistent with the diversity of Latin America, there is profound variability in asthma burden among and within countries in this region. Regional variation in asthma prevalence is likely multifactorial and due to genetics, perinatal exposures, diet, obesity, tobacco use, indoor and outdoor pollutants, psychosocial stress, and microbial or parasitic infections. Similarly, nonuniform progress in asthma management leads to regional variability in disease morbidity. Future studies of distinct asthma phenotypes should follow up well-characterized Latin American subgroups and examine risk factors that are unique or common in Latin America (e.g. stress and violence, parasitic infections and use of biomass fuels for cooking). Because most Latin American countries share the same barriers to asthma management, concerted and multifaceted public health and research efforts are needed, including approaches to curtail tobacco use, campaigns to improve asthma treatment, broadening access to care and clinical trials of non-pharmacologic interventions (e.g. replacing biomass fuels with gas or electric stoves).

    The geography, tourist attractions and the multiple sites of historical and cultural interest make South America as an important destination chosen by travelers. The continent has a wide climatic variation from north to south, making exposure to risk different between the tropics and the temperate or cold regions. In the countries of tropical South America, the greatest risk is associated with the possibility of acquiring vector-borne diseases, like yellow fever, dengue, malaria and leishmaniasis. The risk of acquiring traveler's diarrhea and food-borne illness is similar across the continent, with some variations according to country and to visit urban or rural areas. Rabies, pertussis and diphtheria have appeared as epidemics in several countries and other diseases such as rickettsiosis, hantavirosis and viral encephalitis have expanded their distribution. The geographic and epidemiological diversity of South America, promotes a challenge for travel medicine specialists because during the pre-travel advice they have to take in account the kind of trip, traveller's medical history, exposure to risk and the dynamics of endemic emerging and reemerging diseases in the region.

  19. The management century.

    PubMed

    Kiechel, Walter

    2012-11-01

    In 1886, addressing the nascent American Society of Mechanical Engineers, Henry R. Towne proposed that "the management of works" be considered a modern art--thereby heralding the Management Century, when management as we know it came into being and shaped the world in which we work. Kiechel, a past editorial director of Harvard Business Publishing, elucidates the three eras that punctuate this period: the years leading up to World War II, during which scientific exactitude gave wings to a new managerial elite; the early postwar decades, managerialism's apogee of self-confidence and a time when wartime principles of strategy were adapted, sometimes ruthlessly, to the running of companies; and the 1980s to the present, years that saw fast-moving changes, disequilibrium, and a servitude to market forces but also ushered in globalism, unprecedented innovation, and heightened expectations about how workers are to be treated. Along the way he examines the contributions of thinkers such as Frederick Taylor, Elton Mayo, Peter Drucker, and Michael Porter. What lies ahead? Perhaps the biggest challenge facing the 21st-century company, Kiechel posits, is to truly free the spark of human imagination from the organization's tidal pull toward the status quo. There's almost always a better way, he concludes--and management will continue to seek it. PMID:23155998

    This second joint conference between the APS Topical Group on Shock Compression of Condensed Matter and the International Association for the Advancement of High Pressure Science and Technology (AIRAPT) demonstrates that static and dynamic compression of condensed matter continues to be a vibrant field of science and engineering. It is also by its nature an interdisciplinary field, incorporating chemistry, materials science, solid mechanics, plasma physics, and condensed matter physics, and utilizes theoretical, computational, and experimental tools. Recent years have brought about many advances in loading platforms, diagnostics, and computations that are leading to the emergence of many new avenues of research. These advances are also breathing new life into traditional topics such as equations of state, phase transformations, and chemistry at extreme conditions. The plenary lectures by Gennady Kanel, Karl Syassen, David Ceperley, Jon Eggert, Duck Young Kim, and Richard Kraus spanned the disciplines of static and dynamic high pressure physics and illustrated the breadth of the field. They also showed that interesting and important problems remain for researchers of the future to solve. The main guiding principal in the organization of this conference was to intertwine static and dynamical experimental alongside computational and theoretical studies of similar materials. To achieve this goal, we arranged the conference to include static, dynamic, and computational components in the same sessions, quite often taking presenters out of their comfort zone. The three special sessions on Deep Carbon Budget (organized by Giulia Galli and Rus Hemley), High Energy Density Materials (organized by Raymond Jeanloz and Jon Eggert), and Dynamic Response of Materials (organized by Yogendra Gupta and John Sarrao) furthered this guiding principal. We also endeavored to represent the breadth of static and dynamic high pressure science and technology, notably beyond that done at national laboratories. To this end, a significant fraction of the plenary, invited and contributed presentations showcased work done in academia, defense laboratories and industry, as well as internationally. Although travel distance and visa issues always present difficulties, the conference had strong representation from a record number of international participants, including sizable groups from Russia and China (thanks to Tony Zocher and Frank Cherne), as well as Japan, the United Kingdom, France, Canada, Germany, Israel, and Italy. It is our sincere hope that international interactions that occurred at the conference will lead to further collaborations in the future. Finally, we strived to increase student participation at the conference. Through the leadership of Scott Alexander and his committee, a new all-day student symposium was held the day before the main conference, with only student attendees and presenters, in order to acclimate the students to conference participation and help them network with their peers. In cooperation with the APS Topical Group and the AIRAPT and with additional support from DTRA and the AWE, the conference was able to provide financial assistance to a large number of students to attend the conference and present their research. This aid helped increase the number of student attendees significantly over previous conferences. Finally, the conference sponsored a networking lunch for students and representatives from a number of laboratories and other institutions, which was well attended. Seattle proved itself to be an excellent venue for the conference. The international flavor of the city provided ample dining options and numerous activity choices outside of the conference sessions. The major international airport made travel as easy as possible, as Seattle is a convenient central location for attendees from Europe and Asia. The conference was truly a team effort with critical contributions from many individuals. We deeply appreciate their contributions to the success of the conference and the publication of these proceedings. Gilbert (RIP) Collins David S Moore Choong-Shik Yoo

  11. Anaglyph, South America

    NASA Technical Reports Server (NTRS)

    2003-01-01

    This anaglyph (stereoscopic view) of South America was generated with data from the Shuttle Radar Topography Mission (SRTM). It is best viewed at or near full resolution with anaglyph glasses. For this broad view the resolution of the data was first reduced to 30 arcseconds (about 928 meters north-south but variable east-west), matching the best previously existing global digital topographic data set called GTOPO30. The data were then resampled to a Mercator projection with approximately square pixels (about one kilometer, or 0.6 miles, on each side). Even at this decreased resolution the variety of landforms comprising the South American continent is readily apparent.

    Topographic relief in South America is dominated by the Andes Mountains, which extend all along the Pacific Coast. These mountains are created primarily by the convergence of the Nazca and South American tectonic plates. The Nazca Plate, which underlies the eastern Pacific Ocean, slides under western South America resulting in crustal thickening, uplift, and volcanism. Another zone of plate convergence occurs along the northwestern coast of South America where the Caribbean Plate also slides under the South American Plate and forms the northeastern extension of the Andes Mountains.

    East of the Andes, much of northern South America drains into the Amazon River, the world's largest river in terms of both watershed area and flow volume. Topographic relief is very low in much of the Amazon Basin but SRTM data provide an excellent detailed look at the basin's three-dimensional drainage pattern, including the geologic structural trough (syncline) that hosts the eastern river channel.

    North of the Amazon, the Guiana Highlands commonly stand in sharp contrast to the surrounding lowlands, indeed hosting the world's tallest waterfall, Angel Falls (979 meters or 3212 feet). Folded and fractured bedrock structures are distinctive in the topographic pattern.

    They are unalike and far apart, these 13 past editors of The Journal. Between Nathan S. Davis's first issue and William R. Barclay's retirement, there was almost a century of change in medicine, society, the American Medical Association, prose style, and editorial needs. During these years, the editors ranged from the brilliant organizers John B. Hamilton and George H. Simmons to the diligent John H. Hollister and the devoted Johnson F. Hammond. There were editors with the hot determination of James C. Culbertson, John H. Talbott, and Robert H. Moser, and there were those with the cool precision of Austin Smith and Hugh H. Hussey. They varied from Morris Fishbein, who wrote and spoke "with the grade of an eagle in its unhindered soar," to Truman W. Miller, who wrote scarcely a word. Here, briefly, they are together.

  13. The rise, fall and rise of nurse-midwifery in America.

    For most of history, the care of women, particularly childbearing women, has been delivered by healers and health care providers who were women. This article is an overview of the historical, social, political, economic, and philosophic forces that shaped the role of women, especially midwives, who care for childbearing families. As healers and health care providers, midwives (and later, nurse-midwives) have based their practice on the natural process of pregnancy and birth. Their holistic view dominated childbirth until the 18th century, when the existence of midwives began to be challenged by institutions. In the United States, the marriage of midwifery with nursing in the 1920s, followed by the consumer childbirth revolution of the 1960s, gave new strength to the profession of nurse-midwifery. Later, health economics provided additional support for nurse-midwifery practice, with demonstrated reduced costs and improved quality. At the cusp of the 21st century, internal and external political forces have now led to the inclusion of nonnurses in the profession of midwifery in the United States. Despite the ever-changing political, economic, and societal climate, midwives consistently have brought superior outcomes and family-centered caring to their practice and their patients.

    Plant phenological observations and networks in North America have been largely local and regional in extent until recent decades. In the USA, cloned plant monitoring networks were the exception to this pattern, with data collection spanning the late 1950s until approximately the early 1990s. Animal observation networks, especially for birds have been more extensive. The USA National Phenology Network (USA-NPN), established in the mid-2000s is a recent effort to operate a comprehensive national-scale network in the United States. In Canada, PlantWatch, as part of Nature Watch, is the current national-scale plant phenology program.

    Time and its measurement belong to the most fundamental core of physics, and many scientific and technological advances are directly or indirectly related to time measurements. Timekeeping is essential to everyday life, and thus is the most measured physical quantity in modern societies. Time can also be measured with less uncertainty and more resolution than any other physical quantity. The measurement of time is of the utmost importance for many applications, including: global navigation satellite systems, communications networks, electric power generation, astronomy, electronic commerce, and national defense and security. This paper discusses how time is kept, coordinated, and disseminated in the Americas. PMID:26973371
