    Today astronomical tuning is widely accepted as numerical dating method after having revolutionised the age calibration of the geological archive and time scale over the last decades. However, its origin is not well known and tracing its roots is important especially from a science historic perspective. Astronomical tuning developed in consequence of the astronomical theory of the ice ages and was repeatedly used in the second half of the 19th century before the invention of radio-isotopic dating. Building upon earlier ideas of Joseph Adhémar, James Croll started to formulate his astronomical theory of the ice ages in 1864 according to which precession controlled ice ages occur alternatingly on both hemispheres at times of maximum eccentricity of the Earth's orbit. The publication of these ideas compelled Charles Lyell to revise his Principles of Geology and add Croll's theory, thus providing an alternative to his own geographical cause of the ice ages. Both Croll and Lyell initially tuned the last glacial epoch to the prominent eccentricity maximum 850,000 yr ago. This age was used as starting point by Lyell to calculate an age of 240 million years for the beginning of the Cambrium. But Croll soon revised the tuning to a much younger less prominent eccentricity maximum between 240,000 and 80,000 yr ago. In addition he tuned older glacial deposits of late Miocene and Eocene ages to eccentricity maxima around 800,000 and 2,800,000 yr ago. Archibald and James Geikie were the first to recognize interglacials during the last glacial epoch, as predicted by Croll's theory, and attempted to tune them to precession. Soon after Frank Taylor linked a series of 15 end-moraines left behind by the retreating ice sheet to precession to arrive at a possible age of 300,000 yr for the maximum glaciation. In a classic paper, Axel Blytt (1876) explained the scattered distribution of plant groups in Norway to precession induced alternating rainy and dry periods as recorded by the

  2. Women in 19th Century Irish immigration.

    By the 1950s--100 years after the great famine of 1845-49-- 57% of emigrants from the 26 countries of Ireland were women. In the latter 1/2 of the 19th Century, increasing proportions of women emigrated, until they outnumbered men. For women it was more than a flight from poverty. It was also an escape from an increasingly patriarchal society, whose asymetrical development as a colony curtailed women's social space, even in their traditional role as wife and mother. The famine, which is the single greatest influence forcing emigration, undermined the social fabric of an agrarian society, hastening the process of agricultural transformation. The growth of a new class of Irish a British grazier landlords resulted in a situation of acute land scarcity, encouraging tendencies to cling to one's land holding without dividing it. This, combined with new inheritance practices, gave rise to widespread arranged marriages as a means of land consolidation, and the dowry system. The spontaneous marriage practices of famine days also were replaced by a postponement of marriage. These trends severely reduced the choices exerted by women. The absence of big industrialized cities, which might have absorbed displaced rural populations, removed available options, particularly for women. The system of land monopoly and inheritance revolving around male heads of households reinforced partriarchal relations, within a framework of rigid sexual norms, whose enforcement was easy because the church, which played an important role in the emergence of these values, was a major landowner in itself. The subordinated, invisible status of women in post-famine Ireland, and growing barriers to easy access to marriage partners, to waged employment and self-expression, all helped ensure the higher and higher emigration rates of women. The economic transformation of Irish agriculture accelerated the establishment of oppressive values and helped depreciate the position of women to a very low level. The

  3. Technical improvements in 19th century Belgian window glass production

    Glass was used since the Roman age in the building envelope, but it became widely applied together with iron since the 19th century. Belgium was a major producer of window glass during the nineteenth century and the majority of the produced window glass was exported all over the world. Investigating the literature on the development of 19th century Belgian window glass production is therefore internationally relevant. In the 17th century, wood was replaced as a fuel by coal. In the 19th century, the regenerative tank furnace applied gas as a fuel in a continuous glass production process. The advantages were a clean production, a more constant and higher temperature in the furnace and a fuel saving. The French chemist Nicolas Leblanc (1787-1793) and later the Belgian chemist Ernest Solvay (1863) invented processes to produce alkali out of common salt. The artificial soda ash improved the quality and aesthetics of the glass plates. During the 19th century, the glass production was industrialized, influencing the operation of furnaces, the improvement of raw materials as well as the applied energy sources. Although the production process was industrialized, glassblowing was still the work of an individual. By improving his work tools, he was able to create larger glass plates. The developments in the annealing process followed this evolution. The industry had to wait until the invention of the drawn glass in the beginning of the 20th century to fully industrialise the window glass manufacture process.

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

    Pediatrics began under the most unfavorable conditions that are difficult to imagine nowadays. Children at the start of the 19th century were considered as negligible. The death rate was tremendous, increased by the work of children in factories as soon as 6 years of age in textile industries. In upper classes, infants were fed by a wet nurse, far from their parents and death rate was high as well. The emergence of pediatrics was the result of work carried out in adult medicine in the first half of the 19th century: clinical anatomic method, knowledge of contagious diseases even before the discovery of bacteria, birth of bacteriology. During the whole century, infectious diseases contributed in a large part to children mortality, as that of adults, by cholera, typhus, variola, diphtheria, measles and tuberculosis. Progresses noted during the 2nd part of the century resulted from beginning of hygiene, antisepsis, nutrition improvement, taking consideration of children as human being asking for protection. In contrast, therapeutics as serotherapy, vaccinations at the break of the 20th century played a secondary role.

    This paper explores the major role of suicide in the cultural criticism deployed by 19th century Spanish doctors by analysing the most important theoretical models that inspired their contributions to its aetiology. In the first half of the century, the most commonly debated causal factor was the passions, which were thought to stand in a permanent tension with a free, reflexive and conscious self, in accordance with the spiritualist doctrine that was then dominant. In the context of a growing somatisation of moral and intellectual phenomena, the notion of suicide as an act of free will was later modified, and it became considered the consequence of certain organic disturbances. However, this process did not alter the central role of suicidal behaviour within 19th-century cultural criticism, because the advent of degeneration theory meant that doctors finally had a doctrine that allowed them to combine biological determinism with the extended perception of a moral and social crisis threatening the stability and achievements of bourgeois society.

    The paper focuses on the role that instruments played in the medical discourse of the 19th century. Towards the end of the century, instruments had imbued the medical sciences to such an extent that the situation soon was compared to the vernacular confusion of the biblical tower of Babel. Whereas the autonomical recordings of laboratory apparatus, vouched for guarantee against biased test results, clinicians and general practitioners were finding it difficult to incorporate the new techniques into their daily routines. A tension between the instrument as invention, moulded to fit a particular series of experiments, and the instrument as a reproducible item, was inevitable. Hence, the unification of the science and practice of medicine, became an important topic at the international medical meetings of the late 19th century. Seen in the light of the industrialization and urbanization of occidental culture and society, the instrumentation of medicine entailed a number of significant issues which hinged on the relationship between the biological destiny of man and the artificial wonders of technology. Grand metaphors like the organic machine and the human motor, did not only signal a scientific preoccupation with the shortcomings of the living organism as opposed to the perfection of the machine, but also indicated closer ties between the human body and technology at large. In a certain sense, medical instruments, along with apparatuses such as the camera, the steam-engine, the telegraph, the phonograph and the cinematograph, offered a new set-up of codes with which the body and its functions could be reinterpreted. In this respect, the late nineteenth-century strive for the standardisation and unification of medical instruments, was not irreconcilable with the notion of the l'homme moyen, as conceived, for example, in the work of the Belgian mathematician Adolphe Quetelet. The paper outlines the span of medical measuring devices, dating from the sphygmometer of

    Florence Nightingale (1820-1910) received a clear and profoundly moving Call to serve God at the age of 16. Through a lifetime of hard work and discipline, she became a practicing mystic in the Western tradition, thereby becoming an instrument of God's love, which was the primary source of her great energy and the fabled "Nightingale power." To understand the life and work of this legendary healer, who forever changed human consciousness, the role of women, and nursing and public health systems in the middle of the 19th century, it is necessary to understand her motivation and inspiration. The purpose of this article is to discuss her life and work in the context of her mystical practice and to show the parallels between her life and the lives of three recognized women mystics.

    Medical journals and other sources do not show evidence that cholera occurred in Haiti before 2010, despite the devastating effect of this disease in the Caribbean region in the 19th century. Cholera occurred in Cuba in 1833–1834; in Jamaica, Cuba, Puerto Rico, St. Thomas, St. Lucia, St. Kitts, Nevis, Trinidad, the Bahamas, St. Vincent, Granada, Anguilla, St. John, Tortola, the Turks and Caicos, the Grenadines (Carriacou and Petite Martinique), and possibly Antigua in 1850–1856; and in Guadeloupe, Cuba, St. Thomas, the Dominican Republic, Dominica, Martinique, and Marie Galante in 1865–1872. Conditions associated with slavery and colonial military control were absent in independent Haiti. Clustered populations, regular influx of new persons, and close quarters of barracks living contributed to spread of cholera in other Caribbean locations. We provide historical accounts of the presence and spread of cholera epidemics in Caribbean islands. PMID:22099117

  11. "Depressive pseudodementia" or "Melancholic dementia": a 19th century view.

    1985-01-01

    Nineteenth century views on the interaction between dementia, depressive illness, general paralysis and brain localisation are discussed in the context of a book by A Mairet entitled: Melancholic Dementia. It is shown that by 1883 there was already awareness of the fact that severe affective disorder could lead to cognitive impairment. General paralysis was the commonest diagnosis put forward to account for patients with depression who went on to develop dementia. Patients so diagnosed, however, often recovered and clinical and statistical analysis of Mairet's case histories suggests that some were in fact suffering from depressive pseudodementia. Evidence is marshalled to show that during the 19th century there was wide disagreement concerning the clinical domain, course and even histopathology of general paralysis. This casts doubt on the traditional view that this condition served as "a paradigm" for other psychiatric diseases during this period. It is shown that by the turn of the century these difficulties led to a redefinition of the concept of dementia and to a marked narrowing of the clinical bounds of general paralysis. PMID:3889224

    1999-01-01

    The first legislation in the world, designed to protect animals used in research, was passed in England in 1876, and is still in force today. It is one of the strictest in Europe. At the same period, France had no such law, and was the country conducting the greatest amount of animal experimentation. Comparing, these two countries, in the middle of the 19th century, can account for this difference. The most important difference seems to be related to the theological question: are animals endowed with a soul? Saint Augustine, claimed, in the 4th century, perhaps because of an experiment with the centipede, that animals do not have a soul. In the 17th century, René Descartes, using a different philosophical system, reached a similar conclusion, in France. On the other hand, under the influence of Charles Darwin, England rejected the Roman Catholic conclusion, about the soul of animals. The industrial revolution, occurring earlier in England than in France, also changed the society, developing urban areas, where people were cut off from rural life and changing human relationships with animals. The industrial revolution enabled the development of the press, giving impetus to public opinion. These facts, combined with a caution of science, which was more developed in England than in France, brought about the first important "anti-doctor" campaign.

    Gymnastics as a way of healing and of preserving health spread in Hungary--almost exclusively among higher classes--only in the first half of the 19th century. The movement was inspired by naturopathic theories of the time, first of all by Christoph Wilhelm Hufeland's macrobiotics, by Vinzenz Priessnitz's hydrotherapy and by his healing gymnastics. Gymnastics has been utilized from the 30ies by a new bough of medicine, orthopaedy. The so called Swedish Gymnastics invented by Per Henrik Ling and by his son Hjalmar Ling or the method of the German gymnast Adolf Spiess were well known in Hungary as well. The pediatrist Agost Schöp-Merei founded the first Institute for Gymnastics in Pest in 1835. As orthopaedy developed, gymnastics was more and more utilized in curing locomotor disorders. Gymnastics however stood in close connection with hydropathy as well. Several institutes for hydropathy and gymnastics were founded in the 50ies and 60ies throughout the country. The most popular of them were those of Károly Siklósy and Sámuel Batizfalvy. Preventive gymnastics gained popularity only in the second half of the 19th century, as 1830 the French gymnast Ignatius Clair moved to Pest and founded the "Pester gymnastische Schule" (Gymnastics School of Pest). This private school flourished till 1863. The Gymnastic Federation of Pest (later National Gymnastics Federation), the first Hungarian sport club was founded in 1866. Tivadar Bakody played an important role in its creation. Gymnastics and sport at the beginning were closely connected with fire-service, so gymnastics clubs often functioned also as fire-guard-bodies. In the 70ies and 80ies the social basis of sport movement was slowly broadened out. The end of the century saw already 44 gymnastics-clubs in Hungary united in a single union, the National Federation of Gymnasts, which organized the education of the profession as well. The trend of development didn't cease up to the Great War. This time the movement was

    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.

    Reading faces for identity, character, and expression is as old as humanity but representing these states is relatively recent. From the 16th century, physiognomists classified character in terms of both facial form and represented the types graphically. Darwin distinguished between physiognomy (which concerned static features reflecting character) and expression (which was dynamic and reflected emotions). Artists represented personality, pleasure, and pain in their paintings and drawings, but the scientific study of faces was revolutionized by photography in the 19th century. Rather than relying on artistic abstractions of fleeting facial expressions, scientists photographed what the eye could not discriminate. Photography was applied first to stereoscopic portraiture (by Wheatstone) then to the study of facial expressions (by Duchenne) and to identity (by Galton and Bertillon). Photography opened new methods for investigating face perception, most markedly with Galton's composites derived from combining aligned photographs of many sitters. In the same decade (1870s), Kühne took the process of photography as a model for the chemical action of light in the retina. These developments and their developers are described and fixed in time, but the ideas they initiated have proved impossible to stop.

    The rise of neurophysiology in the 19th century was kindled by Luigi Aloysius Galvani's revolutionary claim for animal electricity at the end of the preceding century. He was first challenged by Allessandro Giuseppe Antonio Anastasio Volta who showed that the muscle twitch in Galvani's experiment was the result of electric stimulation rather than of an enabled biological current. The controversy between Galvani and Volta became a predominant and stimulating issue among the scientists of the early century and found its ultimate elucidation only 40 years later by the pioneering work of Carlo Matteucci of Pisa and Emil Heinrich Du Bois-Reymond of Berlin, who both deserve the reknown as founders of modern neurophysiology. As the first influential promoter and mastermind of the experimental physiology, François Magendie of Paris primarily investigated the nervous system and inaugurated the lesion experiments to clarify specific functions of neural structures. Johannes Müller founded the German school of physiology with its eminent neurophysiological offspring: Du Bois-Reymond, Hermann Ludwig Ferdinand von Helmholtz, and Eduard Friedrich Wilhelm Pflüger. It was Helmholtz's merit to have for the first time precisely assessed the motor conduction velocity by measuring the time interval between two different stimulation sites of the sciatic nerve of the frog. In their brilliant work published in 1870 Gustav Theodor Fritsch and Eduard Hitzig demonstrated that appropriately located focal electrical stimulation of the exposed cortex of dogs induces movement of the contralateral limbs and unequivocally disproved the then prevailing dogma of holistic capacity of the hemispheres, which denied localised functions within the cortex.(ABSTRACT TRUNCATED AT 250 WORDS)

    Absinthe, a bitter spirit containing wormwood (Artemisia absinthium L.), was banned at the beginning of the 20th century as consequence of its supposed unique adverse effects. After nearly century-long prohibition, absinthe has seen a resurgence after recent de-restriction in many European countries. This review provides information on the history of absinthe and one of its constituent, thujone. Medical and toxicological aspects experienced and discovered before the prohibition of absinthe are discussed in detail, along with their impact on the current situation. The only consistent conclusion that can be drawn from those 19th century studies about absinthism is that wormwood oil but not absinthe is a potent agent to cause seizures. Neither can it be concluded that the beverage itself was epileptogenic nor that the so-called absinthism can exactly be distinguished as a distinct syndrome from chronic alcoholism. The theory of a previous gross overestimation of the thujone content of absinthe may have been verified by a number of independent studies. Based on the current available evidence, thujone concentrations of both pre-ban and modern absinthes may not have been able to cause detrimental health effects other than those encountered in common alcoholism. Today, a questionable tendency of absinthe manufacturers can be ascertained that use the ancient theories of absinthism as a targeted marketing strategy to bring absinthe into the spheres of a legal drug-of-abuse. Misleading advertisements of aphrodisiac or psychotropic effects of absinthe try to re-establish absinthe's former reputation. In distinction from commercially manufactured absinthes with limited thujone content, a health risk to consumers is the uncontrolled trade of potentially unsafe herbal products such as absinthe essences that are readily available over the internet.

    There are several reasons for dealing with cholera in the 19th century: it acted as a spotlight throwing into sharp relief the darkest corners of society that are seldom mentioned in the sources. We learn about everyday life in large parts of the population, especially the poor. The fight against the disease also reveals how a society worked socially and politically. When cholera arrived in Europe -- the first time was in the 1830's and several times after that--the population reacted very violently, often by lynching doctors, while the authorities more or less let matters take their course. That is why international researchers have come to see cholera as a catalyst for the constantly latent social unrest following in the train of wars and revolutions. During my research on cholera in Denmark it became clear to me that matters were different here. There were no riots, nor any signs of social unrest--neither before nor after the outbreak of cholera. On the contrary, the authorities and the population joined forces against the epidemic. There was an atmosphere of mutual trust, and almost everybody turned out to be worthy of such trust. That points to a balanced society based on consensus, so cholera also functions as a detector of the fundamental structure of a society.

    There is a growing interest by art conservators for laser cleaning of organic materials, such as wooden artworks, paper and textiles, since traditional cleaning with solvents can be a source of further decay and mechanical cleaning may be too abrasive for sensitive fibers. In this work we present a successful laser cleaning approach for 19th century rattan mats from the Brooklyn Museum collection of African Art, now part of the study collection at the Conservation Center in New York. Tests were carried out using the fundamental (1064 nm) and second harmonic (532 nm) wavelength of a Q-switched Nd:YAG laser to measure threshold values both for surface damage and color changes for different types of rattan samples. The irradiated substrates were investigated by optical microscopy, scanning electron microscopy and by UV-vis spectroscopy in order to determine the efficiency of laser cleaning and to assess possible deterioration effects that may have occurred as a result of laser irradiation. The study showed that by using the laser emission at 532 nm, a wavelength for which photon energy is below the bond dissociation level of the main cellulosic compounds and the water absorption is negligible, it is possible to select a range of laser fluences to remove the black dust layer without damaging the rattan material.

    In the early 19th century, the discoveries of new substances in the healthy and diseased body spawned a search for chemical explanations for physiologic phenomena to guide medical diagnosis and control therapy. William Prout's work on the nature and treatment of diseases of the urinary organs established his reputation as one of Britain's most distinguished physiological chemists. Prout was very skeptical of chemical remedies because of possible side effects, but he suggested iodine treatment for goiter. He emphasized that a satisfactory diet should include carbohydrates, fats, protein, and water. In 1824, he showed that the acid of the gastric juice was hydrochloric acid. Prout applied chemical methods and reasoning to physiology and was criticized for his view that the body's vital functions could be explained by chemistry. His remedy for lack of progress in animal chemistry was for physiologists to become chemists. Prout stimulated much discussion on atomic theory by his hypothesis that the atomic weights of all chemical elements are whole-number multiples of the atomic weight of hydrogen and that the chemical elements were condensed from hydrogen atoms.

    Even before the discovery of the electromagnetism by Oersted, and before Ampère, who attributed all magnetism to the flux of electrical currents, A. v. Humboldt and Hansteen had turned to geomagnetism. With the help of the "Göttinger Magnetische Verein", a worldwide cooperation under the leadership of Gauss game into existence. Even today, Gauss' theory of the geomagnetism is one of the pillars for geomagnetical research work. Thereafter, J. v. Lamont, Prof. in Munich, took over the leadership in Germany. In England, the Magnetic Crusade was started by the initiative of John Herschel and E. Sabine. At the beginning of the forties, James Clarke Ross advanced to the Antarctic Continent, which was then quite unknown. Ten years later, Sabine was able to gather solar-terrestrial relations from the data of the colonical observatories. In the eighties, Arthur Schuster, following Balfour Stewart's ideas, succeeded in interpreting the daily variations of the electrical process in the high atmosphere. The geomagnetic research work in Germany was given a fresh impetus by the First Polar Year 1882-1883. Georg Neumayer, director of the "Deutsche Seewarte" in Hamburg, had been one of the initiators of the Polar Year. He had a close cooperation with the newly founded "Kaiserliches Marineobservatorium" in Wilhelmshaven, and he also managed to gain the collaboration of the "Gauss-Observatorium für Erdmagnetismus" in Göttingen under E. Schering. In the Polar Year, the first automatic recording magnetometers (Kew-Model) were used in a German observatory in Wilhelmshaven. Here M. Eschenhagen, who later became director of the geomagnetic section in the new Meterological-Magnetic Observatory in Potsdam, gained special merit. The treatise considers preceding hypotheses of geomagnetism as well as the palaeomagnetic studies. The essential seismological investigations at the turn of the 19th to the 20th century are briefly treated. They represent one of the keystones for the modern

    Spain was a scientifically backward country in the early 19th century. The causes were various political events, the War of Independence, and the reign of Fernando VII. The introduction of contemporary physics into textbooks was therefore a slow process. An analysis of the contents of 19th-century Spanish textbooks is presented here, centred on imponderable fluids, the concept of energy, the mechanical theory of heat, and the kinetic theory of gases.

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

    PubMed

    Weston, Robert

    2012-01-01

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

  14. The purple coloration of four late 19th century silk dresses: A spectroscopic investigation

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

  15. Moral medicine: symbolic content in 19th century Shaker therapeutics.

    PubMed

    Idler, E L

    1989-03-01

    This paper presents an analysis of the symbolic meanings implicit in an ostensibly empirical therapeutic system. The Shakers, a celibate communal religious order founded in New York State in the mid 1770s, were practitioners of botanic medicine, as were many other Americans in the nineteenth century. This study analyzes the therapeutic properties of the herbs they produced (such as diuretic, stimulant, narcotic, emetic, astringent), using a classification scheme based on the location of the botanical substance's effect vis-à-vis body boundaries and surfaces. The Shakers' beliefs about the therapeutic properties of their herbs are compared with similar analyses of the properties given by two contemporary nineteenth century New England proponents of herbal medicine, botanist Constantine Rafinesque and sectarian practitioner Samuel Thomson. The comparison shows systematic variation in emphasis given to herbs which regulate internal body processes, or act through the openings of the body or on its surface. In this context Shaker medicine can be characterized as quickening, internal, and purifying in its effects on body processes, effects which are highly consistent with Shaker religious beliefs in active, physical worship, selflessness and spiritual purification by confession.

  7. The tympanostomy tube: an ingenious invention of the mid 19th century.

    PubMed

    Mudry, Albert

    2013-02-01

    The introduction of the tympanostomy tube in the treatment of otitis media with effusion in the mid 20th century completely revolutionized its therapy. Nevertheless, it was not a new idea. The aim of this research is to elucidate the origin of prosthetic middle ear ventilation in the mid 19th century. A review of primary sources revealed at least seven different models of tympanostomy tube which were manufactured between 1845 and 1875. These included: Frank's gold tube, Lincke's rubber tube, Bonnafont's silver cannula, Politzer's hard rubber drain, Miot's metallic eyelet, Voltolini's gold ring, and Bonnafont's eyelet. Study of these early innovations shows that all of the technical and surgical principles of the tympanostomy tube were known in the mid 19th century. Widespread introduction into otological practice did not occur until the mid 20th century invention of the operating microscope.

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

    O'Connor, J. E.; Costa, J.E.

    1993-01-01

    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.

    PubMed

    Bachhiesl, Christian

    2012-01-01

    Criminology, which institutionalised at university level at the turn of the 19th century, was intensively engaged in the exploration of superstition. Criminologists investigated the various phenomena of superstition and the criminal behaviour resulting from it. They discovered bizarre (real or imagined) worlds of thought and mentalities, which they subjected to a rationalistic regime of interpretation in order to arrive at a better understanding of offences and crimes related to superstition. However, they sometimes also considered the use of occultist practices such as telepathy and clairvoyance to solve criminal cases. As a motive for committing homicide superstition gradually became less relevant in the course of the 19th century. Around 1900, superstition was accepted as a plausible explanation in this context only if a psychopathic form of superstition was involved. In the 20th century, superstition was no longer regarded as an explanans but an explanandum.

    2009-03-01

    A limited amount of research has been done on the body mass index values of 19th century Americans. This paper uses Texas prison records to demonstrate that, in contrast to today's distributions, most BMI values were in the normal range. Only 21.5% and 1.2% of the population was overweight or obese, while today comparable figures are 36% and 23%. There was also little change in BMI values between 1876 and 1919. Farmers were consistently heavier than non-farmers, while Southwestern men had lower BMI values than their counterparts from other regions of the US. BMI values indicate that 19th century African-Americans, and whites populations were well fed in spite of large expenditures on energy.

    2016-03-01

    During the 19th century a number of elementary and high schools were established for the need of the Greek community of Istanbul. Among the courses included in the curricula were those concerning the scientific study of Nature like Botany, Chemistry and Physics. In the present study we attempt to give a thorough description of the educational material used in these schools for the study of natural sciences with an emphasis in Physics. Especially we shall discuss the books used as course books as well as their probable sources. Furthermore we shall try to make a comparison with the relevant situation in the Greek state and the Ottoman Empire, where modern physics had been already introduced through textbooks based on Ganot's treatise on Physics. The results of our research will give for the first time a picture of the way Greek students in the 19th century Istanbul received their basic knowledge about Physics.

  13. Late 19th- and early 20th-century discussions of animal magnetism.

    PubMed

    Alvarado, Carlos S

    2009-10-01

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

    At the beginning of the 19th century in 1816, Jean Antoine Brutus Menier founded the "Maison Centrale de Droguerie Menier". It supplied most of the pharmacies in France with drugs of animal, plant and mineral origin for the pharmaceutical preparations recommended at that time. The company provided training for many chemists and pharmacists, and as such, had a collection of pots containing over seven hundred drugs that is currently held at the head office of the Council of the College of Pharmacists in Paris. After having described the pot collection, set it against the 19th century background which experienced a real revolution within this profession, and after retracing its history, a study was then carried out in order to compare the former uses with the modern uses for each of the drugs. Thanks to this detailed, comparative analysis it is now possible to evaluate the relevance of the therapeutic range of drugs in the first half of the 19th century, before the significant rise in chemistry. The Germinal Law changed the pharmacist's profession, and with the birth of chemistry, the art of the pharmacy was revolutionised. However, the drugs, and particularly those of plant origin, have managed to keep a dominant position in today's pharmaceutical domain and in the French or European Pharmacopoeia.

  16. The psychologist as a poet: Kierkegaard and psychology in 19th-century Copenhagen.

    PubMed

    Pind, Jörgen L

    2016-11-01

    Psychology had an early start at the University of Copenhagen in the first half of the 19th century, where it was taught as the major part of a compulsory course required of all first-year students. Particularly important in the establishment of psychology at the university was Frederik Christian Sibbern, who was professor of philosophy from 1813 to 1870. Sibbern wrote numerous works on psychology throughout his career. In his first book on psychology, Sibbern expressed the view that the ideal psychologist should also be a poet. Søren Kierkegaard, Sibbern's student, was precisely such a poet-psychologist. Kierkegaard discussed psychology in many of his works, reflecting the gathering momentum of psychology in 19th-century Copenhagen, Denmark. The article brings out some aspects of Kierkegaard's poetic and literary-imaginative approach to psychology. In his opinion, psychology was primarily a playful subject and limited in the questions about human nature it could answer, especially when it came up against the "eternal" in man's nature. Kierkegaard had a positive view of psychology, which contrasts sharply with his negative views on the rise of statistics and the natural sciences. In the latter half of the 19th century, psychology turned positivistic at the University of Copenhagen. This left little room for Kierkegaard's kind of poetic psychology. (PsycINFO Database Record

  17. Parents and children: ideas of heredity in the 19th century.

    PubMed

    Waller, John C

    2003-06-01

    The concept of heredity played a powerful role in structuring 19th-century debates over sickness, morality, class, race, education, social change and evolution. But there was very little agreement as to which qualities were heritable and how new hereditary variants were acquired. In consequence, notions of heredity existed in a wide variety of forms, expressing anything from extreme determinism and a belief in the incorrigibility of individuals, social and racial groups, to unleavened optimism, and a faith in ultimate human perfectibility. This article explores these rich hereditarian discourses to convey an impression of a century that was at least as preoccupied with the concept of biological inheritance as we are today.

    This paper offers an analysis of the process of institutionalization of psychological knowledge in Spain following the educative reforms implemented during the second third of the 19th century, which prescribed its inclusion in the curricular program of the new secondary education. After a detailed examination of the theoretical orientation, the ideological assumptions and the socio-political connections of the contents transmitted to the students throughout the century, its militant spiritualism is interpreted as a highly significant attempt on the part of the liberal elites to articulate a pedagogy of subjectivity intended to counteract the trends toward reduction, naturalization and fragmentation of psychic life inherent to the development of modern science.

  19. Glacier changes on South Georgia since the late-19th century documented in historical photographs

    Gordon, John; Haynes, Valerie

    2014-05-01

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

    2014-01-01

    This review article draws on scarce and poorly studied archival information and several published articles to describe the development and organisation of public health services in the town of Bakar over the 18th and 19th century. For a short while at the turn of the 19th century, Bakar established a hospital run by two physicians and one surgeon to treat patients affected by the so called Škrljevo disease, an endemic type of syphilis. As the century went on, the number of healthcare providers increased by two more physicians, four surgeons, and three to six licensed midwives. There was also a town pharmacy, that worked all that time. As a busy port, the town also provided well-organised maritime sanitary services. As its economy changed over the two centuries to come to a halt after an initial boom, which resulted in a severe drop in population from 7600 to 2000 people, public services deteriorated, including public health. Maritime services suffered the hardest blow, while the workforce gradually came down to one or two physicians and surgeons and several midwives.

    Tuberculosis is one of most ancient diseases affecting human populations. Although numerous studies have tried to detect pathogenic DNA in ancient skeletons, the successful identification of ancient tuberculosis strains remains rare. Here, we describe a study of 140 ancient subjects inhumed in Yakutia (Eastern Siberia) during a tuberculosis outbreak, dating from the 16(th)-19(th) century. For a long time, Yakut populations had remained isolated from European populations, and it was not until the beginning of the 17(th) century that first contacts were made with European settlers. Subsequently, tuberculosis spread throughout Yakutia, and the evolution of tuberculosis frequencies can be tracked until the 19(th) century. This study took a multidisciplinary approach, examining historical and paleo-epidemiological data to understand the impact of tuberculosis on ancient Yakut population. In addition, molecular identification of the ancient tuberculosis strain was realized to elucidate the natural history and host-pathogen co-evolution of human tuberculosis that was present in this population. This was achieved by the molecular detection of the IS6110 sequence and SNP genotyping by the SNaPshot technique. Results demonstrated that the strain belongs to cluster PGG2-SCG-5, evocating a European origin. Our study suggests that the Yakut population may have been shaped by selection pressures, exerted by several illnesses, including tuberculosis, over several centuries. This confirms the validity and necessity of using a multidisciplinary approach to understand the natural history of Mycobacterium tuberculosis infection and disease.

    The 19th century was the age of great reform in American history. After constructing of the canal and railroads, the industrialization began and American society changed so rapidly. In this period, there were so many social crisis and American people tried to solve these problems within the several reform movements. These reform movements were the driving forces to control cholera during the 19th century. Cholera was the endemic disease in Bengal, India, but after the 19th century it had spread globally by the development of trade networks. The 1832 cholera in the United States was the first epidemic cholera in American history. The mortality of cholera was so high, but it was very hard to find out the cause of this fatal infectious disease. So, different social discourses happened to control epidemic cholera in the 19th century, these can be understood within the similar context of American reform movements during this period. Board of Health in New York States made a new public health act to control cholera in 1832, it was ineffective. Some people insisted that the cause of this infectious disease was the corruption of the United States. They emphasized unjust and immoral system in American society. Moral reform expanded to Nativism, because lots of Irish immigrants were the victims of cholera. So, epidemic cholera was the opportunity to spread the desire for moral reform. To control cholera in 1849, the sanitary reform in Britain had affected. The fact that it was so important to improve and maintain the water quality for the control and prevention of disease spread, the sanitary reform happened. There were two different sphere of the sanitary reform. The former was the private reform to improve sewer or privy, the latter was the public reform to build sewage facilities. The 1849 cholera had an important meaning, because the social discourse, which had emphasized the sanitation of people or home expanded to the public sphere. When cholera broke out in 1866 again

    British 19th century painters such as J. M. W. Turner, commonly modified the properties of their paint by using gels called "gumtions". These gels allowed them to easily tune the paint handling and drying properties. The fascinating properties of these "gumtions" were obtained by adding lead acetate to a ternary system based on mastic resin, linseed oil and turpentine. Herein, we report and investigate in depth the rheological properties of these gels as well as their structure at a molecular and supra-molecular scale.

    As a consequence of the industrialization German cities grew very rapidly during the 19th century. Nuremberg reached the number of 100 000 in 1881. Although that city had a large Municipality Hospital (since 1845), a number of specialized private hospitals was founded. Julius Cnopf, a doctor from Nuremberg, founded a children's hospital, one of the first children's hospitals in Germany. The Nuremberg Muncipality Hospital had more than 1000 beds before 1914 and many more than 2000 after 1945, for this reason the number of private owned hospitals remained rather small. Nonetheless were these small and highly specialized hospitals quite important for the city population of Nuremberg.

    Social and behavioral scientists have increasingly attended to the contexts and motivational dynamics underlying parricidal events. These efforts notwithstanding, most research has focused on adolescent or adult male offender populations. One largely neglected area of study is that of adult female offender parricide. The present study utilizes archival records to examine the contexts and sources of conflict that gave rise to adult female offender parricides in the late 19th century. Three general themes emerged, representing the primary contexts behind adult female offender parricide: (1) abuse and neglect; (2) instrumental, financially-motivated killings; and (3) expressive killings, often during the course of arguments. Each of these contexts is explored.

    This article explores the paths through which percentage imposed itself in the political sciences. At first used in the financial domain, percentage is incorporated in 1662 by Graunt in the field of studies of mortality; in the beginning of the 19th century it migrates towards studies in population growth, then it migrates to other territories to become a tool of general application. Each migration enters the framework of a new problematic: "the birth of mortality" in one case; "the birth of population" in the other. The recourse to percentages thus appears as one of the elements in the foundation of statistical objectivism.

    Until the last third of the 19th Century in Canada, physicians looked for the causes of infectious diseases and adopted explicative models associated to airist theories, climatic variations and the physical environment. Rarely did they mention the social environment. Yet, the interpretation of disease plays a fundamental role in the elaboration of preventive measures. Consequently, Canadian physicians adopted a naturalist approach based on local sanitation rather than a social approach of the disease. This reinforced the concept of "predisposing causes". By examining local conditions and, to a lesser extent, the living conditions of Quebec's population, the pre-bacteriologist theories prepared the way for the intervention of modern hygienists.

  9. Accounts from 19th-century Canadian Arctic explorers' logs reflect present climate conditions

    Overland, James E.; Wood, Kevin

    The widely perceived failure of 19th-century expeditions to find and transit the Northwest Passage in the Canadian Arctic is often attributed to extraordinary cold climatic conditions associated with the “Little Ice Age” evident in proxy records. However, examination of 44 explorers' logs for the western Arctic from 1818 to 1910 reveals that climate indicators such as navigability, the distribution and thickness of annual sea ice, monthly surface air temperature, and the onset of melt and freeze were within the present range of variability.The quest for the Northwest Passage through the Canadian archipelago during the 19th century is frequently seen as a vain and tragic failure. Polar exploration during the Victorian era seems to us today to have been a costly exercise in heroic futility, which in many respects it was. This perspective has been reinforced since the 1970s, when paleoclimate reconstructions based on Arctic ice core stratigraphy appeared to confirm the existence of exceptionally cold conditions consistent with the period glaciologists had termed the “Little Ice Age” (Figure 1a), with temperatures more than one standard deviation colder relative to an early 20th-century mean [Koerner, 1977; Koerner and Fisher, 1990; Overpeck et al., 1998]. In recent years, the view of the Little Ice Age as a synchronous worldwide and prolonged cold epoch that ended with modern warming has been questioned [Bradley and Jones, 1993; Jones and Briffa, 2001 ;Ogilvie, 2001].

  10. Extending the African instrumental record to the early 19th century

    This paper describes progress toward the production of a data set that extends the African climate record back to the beginning of the 19th century. Qualitative documentary evidence, lake-level fluctuations and other proxy indicators are combined with historical rainfall records to produce regional time series. The data set has relatively high temporal and spatial resolution. The conceptualization is based on a climatic regionalization produced using modern data and an anomaly method in previous historical reconstructions. The data set provides information for some 100 regions with a 1 to 5 year resolution for most of the nineteenth century. Three to five quantitative classes of rainfall are utilized in the data set. Here, the available information to produce this record is summarized. The methodology utilized to combine proxy data and observations to produce a quantitative rainfall data set is described. This historical data set is compared with actual rainfall records for select regions where both are available. This comparison indicates the reliability of the proxy African data set. An analysis of the historical record indicates that the main characteristics of rainfall variability evident in the modern African record are also apparent in the 19th century record. 5 figs.

    From ancient time leprosy has been regarded as a terrifying, stigmatized disease; nevertheless, its cause remained unidentified up to the late 19th century. For centuries numerous leprosy victims worldwide suffered from its morbidity and were socially isolated. The afflicted individuals were segregated because they were considered 'unclean' and had to live in leper colonies, generally under very poor conditions. Physicians believed that leprosy was an incurable, highly contagious, and hereditary disease. In 1873 the Norwegian physician, Gerhard Armauer Hansen (1841-1912), ended the myth of leprosy and discovered its causative agent, known as Mycobacterium leprae. Hansen's discovery was a great triumph in the fight against leprosy. In the 1930's, the first effective antileprosy drug, dapsone, was introduced and in the early 1980's multi-drug therapy was popularized because of high efficacy in resistant cases. Here, we have presented a brief look at the history of leprosy in the world with special focus on the historical account of leprosy in Iran, particularly during the 19th and 20th centuries.

  12. The 'Ajuda Paralyses': history of a neuropsychiatric debate in mid-19th-century Portugal.

    Fontoura, Paulo

    2010-10-01

    The second half of the 19th century witnessed an increasing interest in neurology and psychiatry by Portuguese physicians, in parallel with the overall development of these disciplines in other countries. This process is reflected in the numerous case report publications as well as in debates taking place at the Lisbon Society of Medical Sciences, the major scientific forum of that time. The 'Ajuda Paralyses' were a mysterious succession of epidemics that occurred during 1860-64 in the Ajuda asylum for cholera and yellow fever orphans, which were extensively discussed during 1865-66 by Bernardino Antonio Gomes, Antonio Maria Barbosa, Abel Jordão and Eduardo Motta. Studying this debate helps understand the initial stages of development and the great interest that 'nervous diseases' had for Portuguese clinicians in the mid-19th century and possibly provides one of the first modern descriptions of nutrition-related polyradiculoneuropathy and the ocular findings associated with avitaminosis A. This debate took place at a decisive time for the scientific development of neurology and psychiatry, concurrent with the widespread application of the clinical-anatomical method and neuropathology to the study of diseases of the nervous system, which would set the foundations for our own modern pathophysiological framework. Therefore, the 'Ajuda paralyses' debate also provides a good basis for a discussion on the evolution of the concepts of hysteria and psychosomatic disease and the description of peripheral neuropathy from among a wealth of other entities that did not withstand the test of science.

  13. A comparison of 19th century and current attitudes to female sexuality.

    2007-12-01

    The 19th century medical attitude to normal female sexuality was cruel, with gynecologists and psychiatrists leading the way in designing operations for the cure of the serious contemporary disorders of masturbation and nymphomania. The gynecologist Isaac Baker Brown (1811-1873) and the distinguished endocrinologist Charles Brown-Séquard (1817-1894) advocated clitoridectomy to prevent the progression to masturbatory melancholia, paralysis, blindness and even death. Even after the public disgrace of Baker Brown in 1866-7, the operation remained respectable and widely used in other parts of Europe. This medical contempt for normal female sexual development was reflected in public and literary attitudes. Or perhaps it led and encouraged public opinion. There is virtually no novel or opera in the last half of the 19th century where the heroine with 'a past' survives to the end. H. G. Wells's Ann Veronica and Richard Strauss's Der Rosenkavalier, both of which appeared in 1909, broke the mould and are important milestones. In the last 50 years new research into the sociology, psychology and physiology of sexuality has provided an understanding of decreased libido and inadequate sexual response in the form of hypoactive sexual desire disorder. This is now regarded as a disorder worthy of treatment, either by various forms of counseling or by the use of hormones, particularly estrogens and testosterone.

  14. Human Genetic Variation and Yellow Fever Mortality during 19th Century U.S. Epidemics

    PubMed Central

    2014-01-01

    ABSTRACT We calculated the incidence, mortality, and case fatality rates for Caucasians and non-Caucasians during 19th century yellow fever (YF) epidemics in the United States and determined statistical significance for differences in the rates in different populations. We evaluated nongenetic host factors, including socioeconomic, environmental, cultural, demographic, and acquired immunity status that could have influenced these differences. While differences in incidence rates were not significant between Caucasians and non-Caucasians, differences in mortality and case fatality rates were statistically significant for all epidemics tested (P < 0.01). Caucasians diagnosed with YF were 6.8 times more likely to succumb than non-Caucasians with the disease. No other major causes of death during the 19th century demonstrated a similar mortality skew toward Caucasians. Nongenetic host factors were examined and could not explain these large differences. We propose that the remarkably lower case mortality rates for individuals of non-Caucasian ancestry is the result of human genetic variation in loci encoding innate immune mediators. PMID:24895309

    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.

    The aim to 'civilize' warfare accompanied Medicine and International Law ever since the mid-19th century. However, the entanglement of Medicine and Law, crucial for such an endeavour, has not been taken into consideration so far; likewise, the huge importance of medical knowledge for the perception of wars and their ramifications did not garner much attention in historical research. Hence, by focusing on the 'long' 19th century, this paper shows, firstly, that the production of surgical knowledge during warfare aimed at measuring the effects of combat on human bodies in order to develop prognostic medical knowledge for future wars, as well as maintaining the combat strength of soldiers. Moreover, this knowledge production during warfare strived for the enhancement of medical competence in the diagnosis and treatment of wounds in general. Secondly, I show that this medical knowledge was not only relevant for warfare, but also crucial for the design of International Law: it served to nourish the debates among the so called 'civilized' nations about legitimate and illegitimate weaponry and warfare.

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

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

    2009-01-01

    Very few telescopes were made in America in the 18th century; astronomers needed to rely on distant European makers. While there is evidence of a few American craftsman-made telescopes that were shown at early to mid-19th century Mechanics' Fairs, Massachusetts native Amasa Holcomb appears to have been the first to offer them for sale commercially. Most of Holcomb's instruments were Herschelian reflectors with speculum metal mirrors. Henry Fitz started his optical career by making mirrors used for the first Daguerreotype portrait cameras, and by the mid 1840's he was offering refractors of ever-increasing size. Not long after Fitz started, Alvan Clark began selling telescopes, and the premature death of Fitz in 1863 may have aided Alvan Clark and Sons' rise to prominence. The later decades of the 1800s saw a dramatic increase in the number of college observatories, and with that came more manufacturers to supply the demand.

    Incomplete and non-uniform global observational coverage is a prominent source of uncertainty in instrumental records of global near-surface temperature change. In this study statistical methods are applied to the HadCRUT4 near-surface temperature data set to obtain improved estimates of global near-surface temperature change since the mid 19th century. Methods applied include those that interpolate according to local correlation structure (kriging) and reduced space methods that learn large-scale temperature patterns. The performance of each statistical reconstruction method has been benchmarked in application to a subset of CMIP5 simulations. Model fields are sub-sampled and simulated observational errors added to emulate observational data, permitting assessment of temperature field reconstruction algorithms in controlled tests in which globally complete temperature fields are known. In application to HadCRUT4 data the statistical reconstructions show relatively increased warming in the global average over the 21st century owing to reconstruction of temperatures in high northern latitudes, supporting the findings of Cowtan & Way (2014) and Karl et al. (2015). There is broad agreement between estimates of global and hemispheric changes throughout much of the 20th and 21st century. Agreement is reduced in data sparse periods and regions, notably in the 19th century and in the southern hemisphere. This finding is supported by the results of the climate model based benchmarks and highlights the importance of continued data rescue activities, such as those of the International Surface Temperature Initiative and ACRE. The results of this study will form an addition to the HadCRUT4 global near-surface temperature data set.

    The academic discipline of human geography is concerned with human activities, especially as these relate to physical landscapes and contribute to the modification of those landscapes. Although little attention has been paid to objectivist philosophies to inform human geography, behavior analysis might offer a useful explanatory model. As an example, a behavior analysis of selected aspects of 19th-century Mormon movement and settlement in the intermontane West is conducted. Mormons are a society of believers who practice cooperative effort and support for other members, and the Mormon church is governed by priesthood authority with members being called to perform tasks. This analysis employs the concepts of metacontingency, rule-governed behavior, and delayed reinforcement to analyze how Mormons settled the intermontane West.

    The origin of the Dominican monastery pharmacy is not clear, but sources suggest that it had operated from the eve of the great earthquake in Dubrovnik in 1667 to the beginning of the 19th century. Its last pharmacist, praised for his competence, passed away in 1803, leaving no one behind The prior travelled all the way to Naples to find a competent pharmacist in his stead, but never returned. Story has it that on the way back, the abbot and the pharmacist lost their lives in a shipwreck. The French army occupied the town in 1806, and the monastery was turned into a military camp. Following the retreat of the French army in 1814, the monastery was returned to the Dominicans, but the pharmacy was never restored.

    Using 19th century state prison records, this study contrasts the biological standard of living of comparable US African-American and white females during a period of relatively rapid economic development. White females were consistently taller than black females by about 1.5 cm (0.6 in.). Whites from Great Lakes and Plains states and black Southwestern females were the tallest. US females were tall compared to their European counterparts. The height of females began to decline in the antebellum period, possibly before that of males. The recovery of physical stature was also earlier among females than among males. This implies that the biological standard of lower-class men and women did not move in parallel during the onset of modern economic growth. It also implies that the antebellum puzzle was most likely rooted in the endogenous forces of socio-economic change rather than the exogenous changes in the disease environment.

In this context, it is essential to consider the significant changes taking place in healthcare during this period, also affecting the spaces in which hospital care was offered. Therefore, we focussed our investigation on Santa Casa da Misericórdia Hospital, the most important hospital in the capital of the Brazilian Empire. The sources used are the correspondence between the government and the hospital, the hospital annual reports, archives of the Central Board of Public Hygiene, and wide-circulation medical journals.

    Great developments in study of the central and peripheral nervous system took place throughout the 19th century, especially in Britain. These studies, together with other factors, gave rise to the development of a somaticism of mental illness. The followers of this school of thought, most notably Henry Maudsley, supported the idea of materialism, based on the theory of evolution. They were opposed by those who believed in the duality of body and mind whith its different variants. These two visions constituted the centre of the theoretical debate of psychiatry at that time. The author pays special attention to the first stance and reaches the conclusion that this process of knowledge made mental illness to be considered as an organic disease and contribuited to the entry of the lunatic wholly into the sphere or medical action.

    Current progress in underwater archeology is based on a rich arsenal of high-tech appliances, among which sonar technology plays a key role; it enables scientists not only to detect submerged archeological objects, but to examine them in high definition without having to conduct diving operations or use expensive underwater unmanned vehicles. While the majority of sensational scientific discoveries using sonar have been made in saltwater environments, freshwater ones, rivers in particular, have seen limited activity. The river Yenisei in central Siberia contains an unrecorded number of shipwrecks that await being discovered and studied. In this article we focus on the peculiarities of using sonar for detecting archeological sites on the Yenisei. This article is based on the results of the 2016 expedition, which has determined the location of Thames, a 19th century British steam schooner which was wrecked on the Yenisei.

As a good example may serve, in the opinion of the present authors, the translation of "Astronomy" by N. Lockyer into Serbian (the book was printed in 1880 in Novi Sad). The translator was Djordje Natošević who translated not the English original, but the German translation. The authors find Natošević an interesting personality. A physician by education he devoted the best part of his life to pedagogy and to enhancing the educational level in Serbian primary and secondary schools in Austria-Hungary of those days. He spent some time also in Serbia. It was then that he translated from German the textbook "Astronomy" by Lockyer, popular in those days.

    The present paper describes the main results obtained from the characterization of a wide range of natural and synthetic ochre samples used in Portugal from the 19th to the 20th century, including powder and oil painting samples. The powder ochre samples came from several commercial distributors and from the collection of Joaquim Rodrigo (1912-1997), a leading Portuguese artist, particularly active during the sixties and seventies. The micro-samples of oil painting tubes came from the Museu Nacional de Arte Contemporânea-Museu do Chiado (National Museum of Contemporary Art-Chiado Museum) in Lisbon and were used by Columbano Bordalo Pinheiro (1857-1929), one of the most prominent naturalist Portuguese painters. These tubes were produced by the main 19th century colourmen: Winsor & Newton, Morin et Janet, Maison Merlin, and Lefranc. The samples have been studied using μ-Fourier Transform Infrared Spectroscopy (μ-FTIR), Raman microscopy, μ-Energy Dispersive X-ray fluorescence (μ-EDXRF), and X-ray diffraction (XRD). The analyzed ochres were found to be a mixture of several components: iron oxides and hydroxides in matrixes with kaolinite, gypsum and chalk. The results obtained allowed to identify and characterize the ochres according to their matrix and chromophores. The main chromophores where identified by Raman microscopy as being hematite, goethite and magnetite. The infrared analysis of the ochre samples allowed to divide them into groups, according to the composition of the matrix. It was possible to separate ochres containing kaolinite matrix and/or sulfate matrix from ochres where only iron oxides and/or hydroxides were detected. μ-EDXRF and Raman were the best techniques to identify umber, since the presence of elements such as manganese is characteristic of these pigments. μ-EDXRF also revealed the presence of significant amounts of arsenic in all Sienna tube paints.

    Astronomer, intellectual, passionate patriot, and refined humanist, Ernesto Capocci Belmonte (Picinisco, May 31, 1798 - Naples, January 6, 1864) was a prominent figure of the scientific, cultural, and political life in Naples around the middle of the 19th century. He acquired international recognition for his studies on the orbits of comets and, since 1833, he was named director of the newly built Osservatorio Astronomico in Capodimonte: A prestigious position that he lost for political retaliation as a result of his participation in the movement against the Bourbon rulers in 1848, but which he regained in 1860 upon the arrival in Naples of Giuseppe Garibaldi. An intuitive and open-minded scholar, he looked always at the contemporary experiences in Europe and, as a scientist and cultivated human being, he sought to serve the community by enthusiastically devoting himself also to education and public outreach. He developed clear interests in literature and, as a forerunner, he dared to tackle the genre of science fiction. His short novel Relazione del viaggio alla Luna fatto da una donna nell'anno di grazia 2057 (Report of the Trip to the Moon done by a Woman in the Year of our Lord 2057), written in the period of his exile from the Observatory and practically given up as lost until a private copy was found in the library of one of Capocci's descendants, offers an interesting overview of astronomical knowledge and taste for the elegance in writing, and gives an unusual, and often ironic, viewpoint on the situation of sciences in Naples in the middle of the 19th century.

  14. Factors influencing the recession rate of Niagara Falls since the 19th century

    The rate of recession of Niagara Falls (Horseshoe and American Falls) in northeastern North America has been documented since the 19th century; it shows a decreasing trend from ca. 1 m y - 1 a century ago to ca. 0.1 m y - 1 at present. Reduction of the flow volume in the Niagara River due to diversion into bypassing hydroelectric schemes has often been taken to be the factor responsible, but other factors such as changes in the waterfall shape could play a role and call for a quantitative study. Here, we examine the effect of physical factors on the historically varying recession rates of Niagara Falls, using an empirical equation which has previously been proposed based on a non-dimensional multiparametric model which incorporates flow volume, waterfall shape and bedrock strength. The changes in recession rates of Niagara Falls in the last century are successfully modeled by this empirical equation; these changes are caused by variations in flow volume and lip length. This result supports the validity of the empirical equation for waterfalls in rivers carrying little transported sediment. Our analysis also suggests that the decrease in the recession rate of Horseshoe Falls is related to both artificial reduction in river discharge and natural increase in waterfall lip length, whereas that of American Falls is solely due to the reduction in flow volume.

  15. 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.

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

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

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

    Many evo-devo studies of the turtle's shell draw hypotheses and support from historical sources. The groundbreaking works of Cuvier, Geoffroy St. Hilaire, Carus, Rathke, Owen, and others are being revived in modern research, and their centuries-old understanding of the turtle's shell reconsidered. In the works of these eminent biologists of the 19th century, comparative anatomy and embryology of turtle morphology set the stage for future studies in developmental biology, histology, and paleontology. Given the impact that these works still make on modern research, it is important to develop a thorough appreciation of previous authors, regarding how they arrived at their conclusions (i.e., what counted as evidence?), whether there was debate amongst these authors about shell development (i.e., what counted as an adequate explanation?), and even why these men, some of the most powerful and influential thinkers and anatomists of their day, were concerned with turtles. By tracing and exposing the context and content of turtle shell studies in history, our aim is to inform modern debates about the evolution and development of the turtle's shell.

    Cholera is an acute infectious disease with high mortality if left untreated. Historically, between the 19th and 20th centuries seven great pandemics of cholera occurred and worldwide, thousands of people died. Based on an old theory, cholera was considered an air-born disease and the emergence of its outbreaks were attributed to bad weather or miasma. However later in the 18th century, British physician John Snow (1813-1858) explained the association of a terrible cholera outbreak in London in 1849 to contamination of the drinking water supply with human excreta. Despite his finding, the causative agent of this dreaded illness was unidentified until later in the 19th century. In 1854, Filippo Pacini (1812-1883) an anatomist from Italy and then in 1883, Robert Koch (1843-1910) the German bacteriologist, discovered ‘vibrio cholerae’ as the etiologic agent. During the major pandemics of cholera in 19th and 20th centuries this illness reached Iran and led to vast depopulation and a crucial impact on the country’s socioeconomic status. Poor public health conditions, lack of a well-organized public health authority for implementing preventive and quarantine measures as well as Iran’s specific geographic location were the main facilitating factors of the emergence of various epidemics, including cholera in Iran. The present paper briefly reviews the cholera outbreaks in Iran during the 19th and 20th centuries. PMID:25197514

    In 1864 a detailed map was made about Walachia, its title is Charta României Meridionale (Map of Southern Romania), it has 112 map sheets, it is often called after his draughtsman: Szathmári's map. The map has an outstanding position in the history of Romanian cartography, because it indicates a turning-point. Before the map, foreigners (Austrians and Russians) had made topographic maps about this vassal principality of the Ottoman Empire. The Austrian topographic survey (1855-1859) - which served as a basis for this map - was the last one and the most detailed of these surveys. The map was made between the personal-union (1859) and independence (1878) of the Danubian Principalities. This map was the first (to a certain extent) own map of the forming country. In consequence of this survey and map, the Romanian mapping institute was founded, which one - based on this survey and map - began the topographic mapping of the country. In the Romanian scientific literature imperfect and contradictory information has been published about this map. Only a dozen copies of the map were kept in few map collections; the researchers could have reached them with difficulties. During our research we processed the circumstances of the survey and mapmaking discovering its documentation in the archives of Vienna, as well as using the Romanian, Hungarian and German scientific literature. We found the copies in map collections from Vienna to Bucharest. We digitized all the map sheets from different collections. We calculated the parameters of the used geodetic datum and map projection. We published on the web, such we made the map reachable for everybody. The map can be viewed in different zoom levels; can be downloaded; settlements can be found using the place name index; areas can be exported in modern projection, so the conditions of that time could be compared with today's reality.

    2004-01-01

    We can observe that after downfall of the November Insurrection the authorities of the Polish Kingdom were effectively engaged in the fight against numerous epidemic diseases plaguing the local society. Among "contagions" of the time there were varicella, "gastric-nervous fever", "gastric-rhinitis fever" and typhus (especially in 1836). As usual, cholera was the most dangerous one. All medical and epidemiological services in the Polish Kingdom were making effective remedial measures in order to neutralize results of the epidemics. The implemented methods were effective enough to limit considerably the incidence and number of deceased during the epidemic, which started in October 1836 and lasted till the next year. An obligation of effective cooperation between the Polish authorities and the Russian army was introduced then. The sanitary action against cholera in 1836-1837 should be very highly assessed from the logistic point of view. The wide action of protective vaccination against varicella and numerous sanitary rules completed the favorable image of the Polish Kingdom sanitary services. All the factors mentioned above lead to a conclusion that in the thirtieth of the 19th century both civil and military authorities of the Polish Kingdom did practically utmost in order to limit negative results of cyclical recurrences of epidemic diseases. It should be also stressed that the protective actions undertaken in that time were both direct and long lasting enterprises.

    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

    Abstract By the late 19th Century, storms plaguing early Victorian systematics and nomenclature seemed to have abated. Vociferous disputes over radical renaming, the world-shaking clash of all-encompassing procrustean systems, struggles over centres of authority, and the issues of language and meaning had now been settled by the institution of a stable imperial museum and its catalogues, a set of rules for the naming of zoological objects, and a new professional class of zoologists. Yet, for all that tranquillity, the disputes simmered below the surface, re-emerging as bitter struggles over synonyms, trinomials, the subspecies category, the looming issues of the philosophy of scientific language, and the aggressive new American style of field biology – all pressed in upon the received practice of naming and classifying organisms and the threat of anarchy. In the midst rose an index. This paper will explore the context of CD Sherborn’s Index Animalium and those looming problems and issues which a laborious and comprehensive “index of nature” was meant to solve. PMID:26877652

    Yankee whalers of the 19th century had major impacts on populations of large whales, but these leviathans were not the only taxa targeted. Here, we describe the "collateral damage," the opportunistic or targeted taking of nongreat whale species by the American whaling industry. Using data from 5,064 records from 79 whaling logs occurring between 1840 and 1901, we show that Yankee whalers captured 5,255 animals across three large ocean basins from 32 different taxonomic categories, including a wide range of marine and terrestrial species. The taxa with the greatest number of individuals captured were walruses (Odobenus rosmarus), ducks (family Anatidae), and cod (Gadus sp.). By biomass, the most captured species were walruses, grampus (a poorly defined group within Odontoceti), and seals (family Otariidae). The whalers captured over 2.4 million kg of nongreat whale meat equaling approximately 34 kg of meat per ship per day at sea. The species and areas targeted shifted over time in response to overexploitation of whale populations, with likely intensive local impacts on terrestrial species associated with multiyear whaling camps. Our results show that the ecosystem impacts of whaling reverberated on both marine and coastal environments.

    The purpose of this historical research project is to examine the contribution of 19th-century religious congregations in the development of the nursing profession, based on the historical example of the Sisters of Charity of Sts. Bartolomea Capitanio and Vincenza Gerosa (or the Sisters of the Holy Child Mary). To this end, sixty three volumes were analysed, all taken from the historical archive of the Generalate of the Sisters of the Holy Child Mary in Milan, in via S. Sofia n.13, with the exception of just one, taken from the Braidense National Library, also in Milan. This research project has highlighted the sociological contribution provided by the Sisters of the Holy Child Mary to the professional nature of nursing, and to the development of the distinctive features of the nursing profession (Greenwood, 1980). All documentary sources were analysed in line with the Chabod historical research method (2006), and for their critical interpretation, a scheme of analysis was created. Two lines of investigation emerged from the data collected: the role of Sister Emilia Vinante as an expert with regard to the nursing profession, and the professional strategies promoted by FIRO (Federation of Italian Religious Nurses). Based on the conclusions of the research project, it may be stated that religious congregations contributed greatly to the nursing profession, leaving a decisive mark on the cultural and professional development of nurses.

    British amateur astronomers collected solar observation data as members of organizations such as the British Astronomical Association (BAA) and Liverpool Astronomical Society (LAS) in the late 1800s. Amateur astronomer Elizabeth Brown (1830-99) served as Solar Section Director of both groups, and not only aggregated solar observations (including hand-drawn illustrations) from observers from around the globe, but worked closely with solar astronomer Edward Maunder and other professionals in an attempt to garner specific types of observations from BAA members in order to answer a number of astronomical questions of the day. For example, she encouraged the monitoring of the growth and decay of sunspot groups and published a number of her own observations of particular groups, urging observers to note whether faculae were seen before the birth of sunspots in a given region, a topic of controversy at that time. She also developed a system for classifying sunspots and sunspot groups based on their appearance, dividing then into 11 types: normal, compound, pairs, clusters, trains, streams, zigzags, elliptical, vertical, nebulous, and dots. This poster will summarize Brown’s important contributions to solar observing in the late 19th century and situate her classification scheme relative to those of A.L. Cortie (1901), M. Waldmeier (1938; 1947) and the modified Zurich system of McIntosh (1966; 1969; 1989).

    The unique observing conditions allowed by total solar eclipses made them a highly desirable target of 19th and early 20th century astronomical expeditions, particularly after 1842. Due to the narrowness of the lunar shadow at the Earth's surface this usually implied traveling to faraway locations with all the subsequent inconveniences, in particular, high costs and complex logistics. A situation that improved as travel became faster, cheaper and more reliable. The possibility to observe an eclipse in one's own country implied no customs, no language barriers, usually shorter travelling distances and the likely support of local and central authorities. The eclipse proximity also provided a strong argument to pressure the government to support the eclipse observation. Sometimes the scientific elite would use such high profile events to rhetorically promote broader goals. In this paper we will analyse the motivation, goals, negotiating strategies and outcomes of the Portuguese eclipse expeditions made between 1860 and 1914. We will focus, in particular, on the observation of the solar eclipses of 22 December 1870 and 17 April 1912. The former allowed the start-up of astrophysical studies in the country while the movie obtained at the latter led Francisco da Costa Lobo to unexpectedly propose a polar flattening of the Moon.

    The reefs surrounding the Gilbert Islands (Republic of Kiribati, Central Pacific), like many throughout the world, have undergone a period of rapid and intensive environmental perturbation over the past 100 years. A byproduct of this perturbation has been a reduction of the number of shark species present in their waters, even though sharks play an important in the economy and culture of the Gilbertese. Here we examine how shark communities changed over time periods that predate the written record in order to understand the magnitude of ecosystem changes in the Central Pacific. Using a novel data source, the shark tooth weapons of the Gilbertese Islanders housed in natural history museums, we show that two species of shark, the Spot-tail (Carcharhinus sorrah) and the Dusky (C. obscurus), were present in the islands during the last half of the 19(th) century but not reported in any historical literature or contemporary ichthyological surveys of the region. Given the importance of these species to the ecology of the Gilbert Island reefs and to the culture of the Gilbertese people, documenting these shifts in baseline fauna represents an important step toward restoring the vivid splendor of both ecological and cultural diversity.

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

    The fine structure of cross-striated muscle and its changes during contraction were known already in considerable detail in the 19th century. This knowledge was the result of studying birefringence properties of muscle fibres under the polarization microscope, a method mainly established by Brücke (Denk Kais Akad Wiss Math Naturwiss Cl 15:69-84, 1858) in Vienna, Austria. The knowledge was seemingly forgotten in the first half of the 20th century before it was rediscovered in 1954. This rediscovery was essential for the formulation of the sliding filament theory which represents the commonly accepted concept of muscle contraction (A.F. Huxley and Niedergerke, Nature 173:971-973, 1954; H.E. Huxley and Hanson, Nature 173:973-976, 1954). The loss of knowledge was the result of prevailing views within the scientific community which could be attributed to "fashion": it was thought that the changes of cross-striations, which were observed under the microscope, were inconsequential for contraction since other types of movements like cell crawling and smooth muscle contraction were not associated with similar changes of the fine structure. The basis for this assumption was the view that all types of movements associated with life must be caused by the same mechanisms. Furthermore, it was assumed that the light microscopy was of little use, because the individual molecules that carry out life functions cannot be seen under the light microscope. This unfortunate episode of science history teaches us that the progress of science can severely be retarded by fashion.

    Gentian violet (GV) has a long and varied history as a medicinal agent. Historically used as an antibacterial and antifungal, recent reports have shown its utility as an antitypranosomal, antiviral and anti-angiogenic agent. The objective of this article is to summarize evidence regarding the efficacy and safety of GV use in dermatology. Recent discoveries have found novel targets of GV, namely NADPH oxidase in mammalian cells and thioredoxin reductase 2 in bacterial, fungal and parasitic cells. These discoveries have expanded the use of GV in the 21st century. Given that GV is well tolerated, effective and inexpensive, its use in dermatology is predicted to increase.

    This study supplemented by three charts and a list of biographies, is, for the first time, encompassing their life-data, their resumés and even their professional careers as well as political commitments shown by more than 200 Silesian students. They, at the University of Breslau, but also at other German universities, had joined the student fraternities in the 20-ies and early 30-ies of the 19th century and, in consequence, were persecuted by state authorities, notably in Prussia and, in the majority of cases, had been sentenced to prison terms of varying degrees. The first demagogic persecution, which happened in the first half of the twenties, culminating in 1822 in the Breslau Arminen Trail and ending up with the staging of the Youth-Association-Trail in 1826, had implicated about 100 Silesians, with a smaller portion of them - apart from teh three Youth-Association Silesians who were sentenced to five years imprisonment in a fortress - getting away with a relatively short "political fortress imprisonment". Later a considerable part of them made a career in the prussian judicial authority, in the institutions of higher learning, as parish priests, physicians and scientists, whereas any political engagement remained a rare exception. Out of the 137 Silesian members of the student fraternities affected by the second wave of persecution, the overwhelming majority of them being Protestants and originating partly from the middle classes, mostly artisans, and from intellectual background, with about a hundred of them being given essentially higher sentences ranging from six years up to capital punishment and, in the event of reprieves, they had to serve their sentences between six months and four-to-six years in a fortress. The majority of them made a medium-level professional career, never exceeding the medium ranks, as judicial officers, lawyers in state or communal services, parish priests, teachers or physicians.

    The material recovery methods used by dust-yards in early 19th century London, England and the conditions that led to their development, success and decline are reported. The overall system developed in response to the market value of constituents of municipal waste, and particularly the high coal ash content of household 'dust'. The emergence of lucrative markets for 'soil' and 'breeze' products encouraged dust-contractors to recover effectively 100% of the residual wastes remaining after readily saleable items and materials had been removed by the thriving informal sector. Contracting dust collection to the private sector allowed parishes to keep the streets relatively clean, without the need to develop institutional capacity, and for a period this also generated useful income. The dust-yard system is, therefore, an early example of organised, municipal-wide solid waste management, and also of public-private sector participation. The dust-yard system had been working successfully for more than 50 years before the Public Health Acts of 1848 and 1875, and was thus important in facilitating a relatively smooth transition to an institutionalised, municipally-run solid waste management system in England. The dust-yards can be seen as early precursors of modern materials recycling facilities (MRFs) and mechanical-biological treatment (MBT) plants; however, it must be emphasised that dust-yards operated without any of the environmental and occupational health considerations that are indispensable today. In addition, there are analogies between dust-yards and informal sector recycling systems currently operating in many developing countries.

    Even before the discovery of electromagnetism by Oersted, and before the work of Ampère, who attributed all magnetism to the flux of electrical currents, A.v. Humboldt and Hansteen had turned to geomagnetism. Through the ``Göttinger Magnetischer Verein'', a worldwide cooperation under the leadership of Gauss came into existence. Even today, Gauss's theory of geomagnetism is one of the pillars of geomagnetic research. Thereafter, J.v. Lamont, in Munich, took over the leadership in Germany. In England, the Magnetic Crusade was started by the initiative of John Herschel and E. Sabine. At the beginning of the 1840s, James Clarke Ross advanced to the vicinity of the southern magnetic pole on the Antarctic Continent, which was then quite unknown. Ten years later, Sabine was able to demonstrate solar-terrestrial relations from the data of the colonial observatories. In the 1980s, Arthur Schuster, following Balfour Stewart's ideas, succeeded in interpreting the daily variations of the electrical process in the high atmosphere. Geomagnetic research work in Germany was given a fresh impetus by the programme of the First Polar Year 1882-1883. Georg Neumayer, director of the ``Deutsche Seewarte'' in Hamburg, was one of the initiators of the Polar Year. He forged a close cooperation with the newly founded ``Kaiserliches Marineobservatorium'' in Wilhelmshaven, and also managed to gain the collaboration of the ``Gauss-Observatorium für Erdmagnetismus'' in Göttingen under E. Schering. In the Polar Year, the first automatic recording magnetometers (Kew-Model) were used in the German observatory at Wilhelmshaven. Here, M. Eschenhagen, who later became director of the geomagnetic section in the new Meteorological Magnetic Observatory in Potsdam, deserves special credit. Early hypotheses of geomagnetism and pioneering palaeomagnetic experiments are briefly reviewed. The essential seismological investigations at the turn of the 19th to the 20th century are also briefly described as

    During the 19th century, numerous figures, with different qualifications, claimed to practice orthopedics: doctors, surgeons, inventors of equipment and instruments, and other empiricists. They performed certain types of techniques, massages, surgical operationsand/or fitted prostheses. The polysemous notion of orthopedics had created conflicts of interest that would reach their height at the end of the 19th century. The integration of orthopedics into the training at the university level enhanced its proximity to surgery, a discipline that has dominated the so-called modern medicine. During the 20th century, various medical branches defend the legitimacy of certain orthopedic practices, thereby threating to a degree the title itself of this specialization. By examining the challenges that have shaped the history of orthopedics in Switzerland, this article also seeks to shed light on the strategies that were implemented in adopting a medical and technical discipline within a transforming society.

    Gentian violet (GV) has a long and varied history as a medicinal agent. Historically used as an anti-bacterial and anti-fungal, recent reports have shown its utility as an anti-typranosomal, anti-viral and anti-angiogenic agent. The objective of this paper is to summarize evidence regarding the efficacy, and safety of GV use in dermatology. Recent discoveries have found novel targets of GV, namely NADPH oxidase in mammalian cells and thioredoxin reductase 2 in bacterial, fungal, and parasitic cells. These discoveries have expanded the use of GV in the 21st century. Given that GV is well tolerated, effective and inexpensive, its use in dermatology is predicted to increase. PMID:24118276

    17th and 19th centuries were particularly important for the development of the Ottoman medicine. Westernization which had already started in the 17th century continued along the 19th and the early 20th centuries. Turkish physicians began to contact with their European colleagues and in this period Latin medical terminology began to appear in the Ottoman medical literature. Sirvanli Semseddin Itaki's work of the 17th century, the Teşrihü'l Ebdan ve Tercüman-i Kibale-i Feylesufan, is the first illustrated Turkish manuscript of anatomy. The illustrations are qualified as developed examples, compared with the medical literature and knowledge of the period. In the 19th century, Sanizade Mehmet Ataullah Efendi (1771-1826) wrote a modern book of anatomy for the Ottoman medical doctors. Miyarü'l Etibba was one of the earliest printed medical books in Turkish. The second volume of Sanizade's Hamse, Miratü'l Ebdan fi Teşrih-i Azai'l Insan is the first printed Ottoman book on anatomy. In Usulü't-Tabia, the third volume of Hamse, the circulatory system is discussed. In this article, we studied the circulatory system described in Semseddin Itaki's Teşrih-ül Ebdan ve Tercüman-i Kibale-i Feylesufan and in Sanizade's Usulü't-Tabia and compared them.

    One of the major Dutch landscapes is formed by lowland rivers. They divide the country in a southern and a northern part, both physically and culturally. We screened the freely available database of 19th and early 20th century paintings of Simonis & Buunk, www.simonis-buunk.com, looking for lowland river landscapes depicting geodiversity and cultural heritage relationships (See References for other landscapes). Emperor Napoleon declared The Netherlands as naturally belonging to his empire as its lands originated from muds originating in France and transported there by the big rivers. A description that may have given rise to the idea of the Netherlands as a delta, but from a geomorphological perspective The Netherlands consists of series of river plains of terrestrial origin, of which the north-western part are subsiding and invaded by the sea. Now, the rivers Meuse and Rhine (including its branches Waal and IJssel) meander through ever larger river plains before reaching the North Sea. They end in estuaries, something one would not expect of rivers with catchments discharging a large part of Western Europe. Apart from the geological subsidence, the estuaries might be due to human interference, the exploitation of peat and building of dikes since the 11th century, heavy storms and the strong tidal currents. Archaeological finds show Vikings and Romans already used the river Rhine system for trading and transporting goods. During the Roman Empire the Rhine was part of The Limes, the northern defence line of the empire. Romans already influenced the distribution of water over the different river branches. Since the middle of the 19th century groins and canalization drastically changed the character of the rivers. The 19th and early 20th century landscape paintings illustrate this change as well as changes in land use. Examples of geodiversity and cultural heritage relationships shown: - meanders and irregular banks disappear as river management increases, i.a. bends

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

    Individual stature depends on multifactorial causes and is often used as a proxy for investigating the biological standard of living. While the majority of European studies on 19th and 20th century populations are based on conscript heights, stature derived from skeletal remains are scarce. For the first time in Denmark this study makes a comparison between skeletal stature and contemporary Danish conscript heights and investigates stature of males and females temporally and between socially distinct individuals and populations in 19th and early 20th century Copenhagen. A total of 357 individuals (181 males, 176 females) excavated at the Assistens cemetery in Copenhagen is analyzed. Two stature regression formulae (Trotter, 1970; Boldsen, 1990) are applied using femur measurements and evaluated compared to conscript heights. The results indicate that mean male stature using Boldsen follows a similar trend as the Danish conscript heights and that Trotter overestimate stature by ca. 6cm over Boldsen. At an inter population level statistically significant differences in male stature are observed between first and second half of the 19th century towards a slight stature decrease and larger variation while there are no significant changes observed in female stature. There are insignificant differences in stature between middle and high class individuals, but male stature differs statistically between cemeteries (p=0.000) representing middle/high class, paupers and navy employees, respectively. Female stature had no significant wealth gradient (p=0.516). This study provides new evidence of stature among males and females during the 19th century and suggests that males may have been more sensitive to changes in environmental living and nutrition than females.

    2006-01-01

    Before the middle of the 19th century urban life was hazardous, life expectancy in big cities was shorter than in the countryside, it was half as high as it is today. Cities used to be called "the graves of mankind"; they were unhygienic, since their inhabitants lived under crowded, unhealthy conditions. In German cities infant mortality was extremely high, one out of three new-born children died within its first year. In most big cities more people died in any given year than were born. In 1806, when the Imperial City of Nuremberg was absorbed by the Kingdom of Bavaria, it had 25 000 inhabitants, fewer than around the year 1600. In the following decades Nuremberg grew quickly, up to 50000 in 1846 and 100000 in 1881, 330000 in 1910. Its population was living extremely crowded within the medieval city-walls, up to 58 000 (1885) in the old parts of the city, more than twice as many as in 1806. Mortality was bound to increase, as more and more people moved to Nuremberg. Mortality rose from 25.5 per thousand in the 1820's to 29.4 in the 1850's and 32.8 in the 1860's. This increase of population was mainly due to migration from outside, from the countryside. New industries settled down in Nuremberg and provided new jobs, the new factories produced lots of smoke and dangerous dust. The general living conditions of the workers were poor, people were much smaller than nowadays. During the industrialisation labor was backbreaking, working hours were extremely long, and annual working hours were more than twice as long as today. New and better legislation was written by the Northern German Confederation, founded in 1867. Now the magistrate of Nuremberg recognised that something had to be done. In the following years physicians began to collect information as to morbidity and mortality in various parts of Nuremberg. Very many people still died of infectious diseases, esp. of tubercolosis, typhoid fever, diphtheria, pertussis, scarlet fever and other infectious diseases. There

    This article uses debates regarding yellow fever causality among leading healers in 19th-century Galveston, Texas, U.S., as a means of exploring the extent to which ideas are social actors. That is, the analysis demonstrates that ideas about yellow fever causality shaped contemporaneous public health policy responses to yellow fever outbreaks in 19th-century Galveston. The article contributes to the growing literature documenting that contagionist and anticontagionist views were often assimilated, and also supports the historiography showing that the predisposing/exciting causes dichotomy is a more robust intellectual framework for understanding 19th-century attributions of disease causality.

    This paper provides an original account of the long-term regional metabolism in relation to the cattle rearing in western France starting by the precise formulation of animal diets at three key dates of the 19th, 20th and 21st centuries. We established links between the demand in fodder of the meat and dairy sectors and the necessary inputs of nitrogen, water and land as well as the land cover changes occurring on the affected local and remote cattle acreage. The average agricultural productivity for fodder supply is estimated at about 50 kg N/ha in the mid-19th, 54 kg N/ha in the early 20th and 150 kg N/ha at the turning of the 21st century. Jointly for the dairy and meat productions, the potential efficiency in the conversion of the vegetal into animal protein more than doubled over the studied period, passing from less than 9% in the 19th to 20% in the 21st century. The current cattle sector is sustained for about 25% by land situated beyond the regional frontiers and uses water at intensities that approach or exceed the availability of renewable water. The nitrogen pollution is expressed in terms of the Net Anthropogenic Nitrogen Inputs (NANI) and, by comparison to the N recovered in products, is used to define the N-Environmental Efficiency of the farming. We discuss the historical succession of the factors that contributed to the growth of the meat and milk production and make a comparison of the impacts and policy between the local and distant resources.

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

    A total of 26,203 of the deaths in Jerez de los Caballeros (Badajoz) during the 19th century were collected and grouped according to the Bertillon's Classification, in order to study the causes of death from rheumatic diseases. An analysis was made using the Death Registers, those located in the Parish Archives, and files of the Municipal Archives. There were a total of 31 deaths due to rheumatic diseases, with the 65-74 years age group being most frequent. The lack of records may be due to the inaccuracy of the diagnoses. September was the month of increased mortality.

    We provide empirical evidence on the existence of the Pigou-Dalton principle. The latter indicates that aggregate welfare is - ceteris paribus - maximized when incomes of all individuals are equalized (and therefore marginal utility from income is as well). Using anthropometric panel data on 101 countries during the 19th and 20th centuries, we determine that there is a systematic negative and concave relationship between height inequality and average height. The robustness of this relationship is tested by means of several robustness checks, including two instrument variable regressions. These findings help to elucidate the impact of economic inequality on welfare.

    During the 19th century, the question of the relation between the soul and the body was deeply renewed by German psychological studies. The new elaborated conception of the relationship between the psychical and the physical coincides with the appearance of a cognitivist paradigm, in which mental phenomena are considered as entities that may be individualised, isolated, and then correlated with the activity of specific neural substrates. German psychologists were confronted with the problem of the correlation between psychical life and the nervous system (localisation of mental phenomena and nature of this correlative relationship), and propose an extensive analysis on the neural conditions and the emergence of psychical processes.

    There has been little attempt to integrate contemporary studies of suicide and mass murder to homicide-suicides. The current research attempts to do so in the context of 19th-century parricides in America. This project uses archival records from The New York Times and the Chicago Tribune, 1851-1899, resulting in a total of 231 incidents. Our results indicate that parricides, mass murders, and suicides tended to originate as spontaneous acts, usually during the course of an argument, gathering momentum as the interaction unfolded. We contend that suicide is one way of alleviating threats to offender's loss of self-identity.

    A casebook written by Dr. John Mackieson (1795–1885), of Charlottetown, contains the records of 49 surgical cases he managed between 1826 and 1857. In view of the rarity of first-hand accounts of surgical practice in Canada in the mid-19th century, Mackieson’s case records are a significant source of information. These cases are discussed in order to delineate Mackieson’s approach to the surgical problems he faced in his general practice. His case records also illustrate some of the general problems that beset surgeons in that era. PMID:11939660

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

    The current study presents some aspects of syphilis in the Balkan Peninsula from the 19th century until the Interwar. Ever since the birth of modern Balkan States (Greece, Bulgaria, Turkey and Serbia), urbanization, poverty and the frequent wars have been considered the major factors conducive to the spread of syphilis. The measures against sex work and sexually transmitted diseases (STDs) were taken in two aspects, one medical and the other legislative. In this period, numerous hospitals for venereal diseases were established in the Balkan countries. In line with the international diagnostic approach and therapeutic standards, laboratory examinations in these Balkan hospitals included spirochete examination, Wassermann reaction, precipitation reaction and cerebrospinal fluid examination. Despite the strict legislation and the adoption of relevant laws against illegal sex work, public health services were unable to curb the spread of syphilis. Medical and social factors such as poverty, citizen's ignorance of STDs, misguided medical perceptions, lack of sanitary control of prostitution and epidemiological studies, are highlighted in this study. These factors were the major causes that helped syphilis spread in the Balkan countries during the 19th and early 20th century. The value of these aspects as a historic paradigm is diachronic. Failure to comply with the laws and the dysfunction of public services during periods of war or socioeconomic crises are both factors facilitating the spread of STDs.

    There is little knowledge on sleepwalking in ancient times even though it is a very common condition. The aim of this report is to describe the backgrounds of medical knowledge on somnambulism in the 19th century, a key period in the development of neurosciences, by analysing its representation in two famous Italian operas: La Sonnambula by Vincenzo Bellini and Macbeth by Giuseppe Verdi. The 19th-century operas may be considered as a crossing point between the popular and intellectual world because they mirror popular answers to phenomena that were still awaiting scientific explanations. Shakespeare's play Macbeth was also considered. In Shakespeare's play and in Verdi's Macbeth, sleepwalking is looked upon as a neuropsychiatric disorder, a manifestation of internal anxiety. In La Sonnambula by Bellini, this condition is considered as common disorder that anticipates scientific theories. The analysed Italian operas provide two different views on sleepwalking, probably because they are based on texts belonging to different periods. Their examination allows one to understand the gradual evolution of theories on sleepwalking, from demoniac possession to mental disorder and sleep disease. At the same time, this analysis throws some light on the history of psychological illnesses.

    The aim of this study was to investigate the health care available for the poor citizens of Split during the first half of the 19th century. Soon after being constructed in 1797, the Civic Hospital in Split founded by the Ergovac brothers for the needs of the poor was transformed into a military hospital. Consequently, caring for this social stratum was taken over by two inadequate shelters and later by a small civic hospital situated in the Split suburb of Dobri. The year of the application of Petar Ergovac to the supreme ruler for the transformation of the hospital building established by his family from a military to a civil institution was found, as well as the correct data regarding its return to initial idea in 1821. On the basis of the archival documents kept in the Archaeological Museum in Split and in the State Archives in Zadar, the work organization of the Civic Hospital in Split and the first stage of its change from a charitable to a public health hospital institution were presented. This study revealed the aspiration of the authorities in the first half of the 19th century to improve the health system of the city of Split.

    Jan Jędrzejewicz was an amateur astronomer who in the 2nd half of the 19th century created an observation centre, which considering the level of research was comparable to the European ones. Jędrzejewicz settled down in Plonsk in 1862 and worked as a doctor ever since but his greatest passion was astronomy, to which he dedicated all his free time. In 1875 Jędrzejewicz finished the construction of his observatory. He equipped it with basic astronomical and meteorological instruments, then began his observations and with time he became quite skilled in it. Jędrzejewicz focused mainly on binary stars but he also pointed his telescopes at the planets of the solar system, the comets, the Sun, as well as all the phenomena appearing in the sky at that time. Thanks to the variety of the objects observed and the number of observations he stood out from other observers in Poland and took a very good position in the mainstream of the 19th-century astronomy in Europe. Micrometer observations of binary stars made in Płońsk gained recognition in the West and were included in the catalogues of binary stars. Interest in Jędrzejewicz and his observatory was confirmed by numerous references in the English "Nature" magazine.

  1. Medical diagnosis of legal culpability: the impact of early psychiatric testimony in the 19th century English criminal trial.

    PubMed

    Toole, Ciara J

    2012-01-01

    Fast-paced developments in psychiatry, neuroscience and emerging neuroimaging technologies place continual pressure on the legal recognition of mental illness and disease across jurisdictional boundaries. Nevertheless, the Canadian legal definition of exculpatory mental disease in the context of criminal liability has remained largely static, sheltered from the immediate influence of medical theory and advancements. In order to effectively reflect on the intersection of mental health and criminal justice systems in this area, it is important to understand its historical development and the English common law origins of the current approach. Specifically turning to the early 19th century, documented history and accounts of early medical witness testimony on the mental state of the accused provide a unique opportunity to understand the initial collision between fundamental concepts of moral and legal culpability and new scientific understandings of mental function and disease. In this article, I suggest that early psychiatric testimony to the accused's mental state challenged the evolving criminal law of 19th century England to reconcile its restrictive definition of "insanity" with expanding scientific reasoning and accounts of mental disease. The trial of Edward Oxford, an attempted royal assassination case of 1840, is examined as a symbolic height in this conflict prior to the first common law pronouncement of the current approach in 1843. As debate continues on the role of medical advancement in the identification of exculpatory medical disorders in law, this historical perspective may serve as a touchstone in balancing the enforcement of legal culpability with our society's greater appreciation for mental illness.

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

    During his long career as a physician in Charlottetown, Dr. John Mackieson (1795-1885) compiled 4 medical manuscripts: 2 sets of case records, a synopsis of the medical conditions that were common in his day and a formulary. As primary sources, these documents provide information about medicine in 19th-century Canada and augment our knowledge of the problems of medical practice in that era. They illustrate aspects of the work of Dr. Mackieson, a generalist with interests in surgery and obstetrics, and they facilitate an understanding of the rationale underlying the treatments that he and his contemporaries used. Although 150 years old, the case records can be appreciated for their relevance to the art of medicine. Two excerpts from the case records, presented in this article, provide a sense of Dr. Mackieson's writings and introduce a discussion on the significance of these manuscripts in relation to the ideas on disease and treatment that governed medical practice, both in Prince Edward Island and elsewhere in Canada, in the 19th century.

    Dune fields are found in several areas of the Great Plains, and though mostly stabilised today, the accounts of early explorers show that they were more mobile in the last century. Using an index of dune mobility and tree ring data, it is found that these periods of mobility were related to temperature-induced drought, the high temperatures increasing evapotranspiration. Explorers also record that rivers upwind of these dune fields had shallow braided channels in the 19th century, and these would have supplied further aeolian sand. It is concluded that these dunes are extremely susceptible to climate change and that it may not need global warming to increase their mobility again. -K.Clayton

    A small collection of antique dental instruments located in the LSU School of Dentistry Library (LSUSD) provides a glimpse into the world of the 19th century dentist. The instruments in this collection, with handles carved from common and rare early materials such as bone, wood, ivory, ebony, cameo, shell and pearl, provide a striking contrast to all-steel instruments of the 20th century. An understanding of their development and function substantially increases appreciation of these instruments, which can be categorized as instruments for oral surgery, prophylaxis, restoration, and general use. In this article, the authors summarize the historical development of each type of instrument and describe the specific items in the LSUSD Library collection.

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

    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.

  9. Paleontology and Darwin's Theory of Evolution: The Subversive Role of Statistics at the End of the 19th Century.

    Tamborini, Marco

    2015-11-01

    This paper examines the subversive role of statistics paleontology at the end of the 19th and the beginning of the 20th centuries. In particular, I will focus on German paleontology and its relationship with statistics. I argue that in paleontology, the quantitative method was questioned and strongly limited by the first decade of the 20th century because, as its opponents noted, when the fossil record is treated statistically, it was found to generate results openly in conflict with the Darwinian theory of evolution. Essentially, statistics questions the gradual mode of evolution and the role of natural selection. The main objections to statistics were addressed during the meetings at the Kaiserlich-Königliche Geologische Reichsanstalt in Vienna in the 1880s. After having introduced the statistical treatment of the fossil record, I will use the works of Charles Léo Lesquereux (1806-1889), Joachim Barrande (1799-1833), and Henry Shaler Williams (1847-1918) to compare the objections raised in Vienna with how the statistical treatment of the data worked in practice. Furthermore, I will discuss the criticisms of Melchior Neumayr (1845-1890), one of the leading German opponents of statistical paleontology, to show why, and to what extent, statistics were questioned in Vienna. The final part of this paper considers what paleontologists can derive from a statistical notion of data: the necessity of opening a discussion about the completeness and nature of the paleontological data. The Vienna discussion about which method paleontologists should follow offers an interesting case study in order to understand the epistemic tensions within paleontology surrounding Darwin's theory as well as the variety of non-Darwinian alternatives that emerged from the statistical treatment of the fossil record at the end of the 19th century.

    The nineteenth century brought the progressive demarcation of the professions devoted to the healing arts in Brazil, with a emphasis on rights and responsibilities. Academic medicine made a growing distinction between those who prescribed medicine and those who engaged in making or selling it. The article explores this process, with an emphasis on pharmaceutical practice in the province of Bahia in the latter half of the century. Within this context, it addresses changes and constancies in laws and in their local enforcement as well as relations between pharmacists, on the one hand, and, on the other, the government, physicians, and those who made or sold medicine illegally or without authorization.

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

    This article analyses the development of military knowledge in France in the 19th century, both in terms of production of knowledge (especially through the Dépôt de la Guerre) and of transmission through a network of army libraries. The strategic dimension of this form of knowledge required a direct intervention of the state, to control or restrict the publication of sensitive data. State intervention was also necessary to coordinate and generate a unified, applied military knowledge using data submitted by members of different army branches, or by civilians. The work of military librarians and bibliologists was all the more difficult because of the very wide range of sciences which could be used by the army. Growing state intervention and public funding were thus essential for the production and transmission of military knowledge.

    This article aims to determine to what extent photographic practices in psychology, psychiatry and physiology contributed to the definition of the external bodily signs of passions and emotions in the second half of the 19(th) century in France. Bridging the gap between recent research in the history of emotions and photographic history, the following analyses focus on the photographic production of scientists and photographers who made significant contributions to the study of expressions and gestures, namely Duchenne de Boulogne, Charles Darwin, Paul Richer and Albert Londe. This article argues that photography became a key technology in their works due to the adequateness of the exposure time of different cameras to the duration of the bodily manifestations to be recorded, and that these uses constituted facial expressions and bodily gestures as particular objects for the scientific study.

    The biological standard of living in Central Italy at the beginning of the 19th century is analyzed using newly collected data on the height of recruits in the army of the Papal States. The results reveal a decline in height for the cohorts born under French rule (1796-1815). Although this trend was common to many parts of Europe, the estimated magnitude of the decline suggests a worsening of the biological standard of living of the working classes in the Papal States even relative to that of other countries. Despite the differences in the economic systems within the Papal States, no significant geographical variation in height has been found: even the most dynamic and advanced regions experienced a dramatic height decline. Mortality also increased during the period under consideration.

    2010-03-01

    In late 19th and early 20th century, criminology became institutionalized as an independent branch of science. Methodologically it focused on the 'exact' methods of the natural sciences, but also it tried to integrate the methods of the humanities. This mix of methods becomes visible in the treatment of blood, which on the one hand was an object of then brand new methods of scientific analysis (identification of human blood by the biological or precipitin method), and on the other hand was analyzed as a product of the magic and superstitious mentalities of criminals. The methodical tension resulting from this epistemological crossbreeding did not disturb the criminologists, for whom the reconciliation of opposite ways of thinking and researching seemed to be possible. In this encyclopaedic analysis of blood early criminology tried to combine the anthropological exploration of vampirism with the chemical and microscopic detection of antibodies and haemoglobin, thus mirroring the positivistic optimism that was then prevalent.

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

    During the nineteenth and twentieth centuries, its growth accompanied the country's political and social changes. In the early half of the nineteenth century, care for the sick depended in part on religious charity. So-called public beneficial care was later introduced and consolidated under president Benito Juárez (1856) and then continued under Porfirio Díaz (1880-1910). The Mexican Revolution (1910-1917) brought the notion that public-health assistance is the State's social responsibility. Health care and social security are now both part of so-called "institutional medicine," which also encompasses research and teaching on public health. This analysis of public-health care in Mexico examines the question of diseases and their control, the emergence of institutions, and the development of the concept of public health.

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

    The present work is a review of the remedies in use in Ferrara against tuberculosis in the 1800s. The work started from the discovery of accounts describing methods and remedies. These remedies were also in use world wide. Of particular interest is the work by Antonio Campana, a famous professor of Pharmaceutical Chemistry and Botany in Ferrara, who wrote a pharmacopoeia which had several editions between 1797 and 1841. The Farmacopea Ferrarese was addressed to the apothecaries of Ferrara. Nevertheless, due to its great reputation it had an international distribution. It provided us with an exhaustive view about the medical field in Ferrara in the early 1800s. The remedies adopted in the city in the second half of the century were in line with those present abroad. The work was also supported by the discovery of statistical accounts of the Sant'Anna hospital from 1871. The manuscript written by Alessandro Bennati enabled elucidation of the methods used to treat tuberculosis in the second half of the century. Bennati's work is an historical document completed by the work of the physician Cesare Minerbi.

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

    Christoph Meiners (1747-1810) was one of 18th-century Europe's most important readers of global travel literature, and he has been credited as a founder of the disciplines of ethnology and anthropology. This article examines a part of his final work, "Untersuchungen über die Verschiedenheiten der Menschennaturen" [Inquiries on the differences of human natures], published posthumously in the 1810s. Here Meiners developed an elaborate argument, based on empirical evidence, that the different races of men emerged indigenously at different times and in different places in natural history. Specifically this article shows how a sedentary scholar who never left Europe constructed a narrative of human origins and migrations on the basis of (1) French theory from the 1750s (Charles de Brosses and Simon Pelloutier) and (2) data gathered by explorers as reported in travel literature (J.R. Forster, Pérouse, Cook, Marsden).

    George William Hill (1838-1914) has long been considered one of the most famous and talented celestial mechanicians of the past century and a half. However, many people have never heard of him and his work. Simon Newcomb said he "will easily rank as the greatest master of mathematical astronomy during the last quarter of the nineteenth century.” After receiving a B.A. at Rutgers in 1859, Hill began work in 1861 at the office of the American Ephemeris and Nautical Almanac in Cambridge, MA. He moved to Washington with the group in 1882 which then became part of the U. S. Naval Observatory. Newcomb, beginning his work on planetary motion, assigned the theory of Jupiter and Saturn to him, calling it about the most difficult topic. Hill's work was published by the USNO in 1890 as A New Theory of Jupiter and Saturn. From 1898 to 1901, Hill lectured on the subject of celestial mechanics at Columbia University in a position created just for him. After 1892 and until his death, he lived at the family homestead in West Nyack, NY. He never married, was something of a recluse, and spent most of his time with his books and research. Hill was an amateur botanist and enjoyed exploring on long walks in the countryside. Many honors and awards came to him during his lifetime, both from the U.S. and abroad, including serving as president of the American Mathematical Society. All of Hill's mathematical and astronomical research was incorporated in The Collected Mathematical Works of George William Hill. This work, containing a preface in French by Poincare, was published in 4 large volumes by the Carnegie Institution of Washington in 1905.

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

    There was a marked rise in scarlet fever mortality in England and Wales in the mid-nineteenth century and spectral analysis of the registration details, 1847-80, shows that the interepidemic interval was 5-6 years, but after 1880 the endemic level fell and the fatal epidemics disappeared. The dynamics of the scarlet fever epidemics can be represented by a linearized mathematical model and because the system is lightly damped, it could be driven by an oscillation in susceptibility. Epidemics were significantly correlated with dry conditions in spring/summer (P < 0.001), suggesting that these produced a low amplitude oscillation in susceptibility which drove the system. Epidemics also correlated (P < 0.001) with an oscillation in wheat prices but at a lag of 3 years, suggesting that malnutrition during pregnancy caused increased susceptibility in the subsequent children which interacted synergistically with seasonal dry conditions. Scarlet fever mortality was sharply reduced after 1880 in parallel with falling wheat prices suggesting that the remarkable period of high scarlet fever mortality (1840-80) was dependent on poor nutritive levels during that time.

    1995-12-01

    Toward the end of the nineteenth and at the beginning of twentieth century significant discussions occurred among geographers, meteorologists and climatologists concerned with the notion of climate variability and anthropogenic climate change, for instance, due to deforestation and reforestation. The authors identify two protagonists of this debate, Eduard Brueckner and Julius Hann, who both accept the notion of climate variability on the decadal scale, but respond in very different ways to the discovery of climate change. Brueckner assessed the impact of climate variability on society (e.g., on health, the balance of trade, emigration to the US), and tried to bring these to the attention of the public, whereas Hann limited himself to the immediate natural scientific problem of monitoring and documenting climate variability. The authors suggest that these discussions and the formation of national governmental and parliamentary committees almost 100 hundred years ago, are not merely of historical interest. In view of present discussions of climate variability and anthropogenic climate change, and the need for adequate socio-economic response strategies, past and now neglected arguments may prove important for methodological and theoretical as well as for practical reasons. The past discussions represent a significant social and intellectual analogy for the present situation. 51 refs., 2 figs.

    The second edition of the United Nations Global Assessment Report on Disaster Risk Reduction in 2011 outlined that the worldwide physical exposure to tropical cyclones increased by 192 per cent between 1970 and 2010. For the past 160 years, the Republic of Haiti has experienced numerous tropical storms and hurricanes which may have directly effected the country's development path. However, statistical data regarding storm frequencies and population densities in space and time show that the population's exposure in Haiti may have more negatively influenced its development than the actual number of storms and hurricanes. Haitians, in particular, those living in urban areas have been exposed to much higher tropical cyclone hazards than rural areas since the second half of the 20th century. Specifically, more storms made landfall in regions of accelerated migration/urbanization, such as, in departments Ouest, Artibonite, Nord, and Nord-Ouest with Haiti's four largest cities Port-au-Prince, Gonaives, Cap-Haitien and Port-de-Paix.

  14. Cooking up a culinary identity for Belgium. Gastrolinguistics in two Belgian cookbooks (19th century).

    2013-12-01

    The notion of cookbooks as socio-historic markers in a society is generally accepted within food studies. As both representations and prescriptions of food practices, perceived habits and attitudes towards food, they represent a certain identity for their readers. This paper investigates the nature of the identity that Belgian cookbooks constructed through their rhetoric. An important part of this study is to explore how and to what extent explicit reference to Belgium was made. To this end recipe titles/labels and recipe comments used in two leading bourgeois cookbooks from nineteenth-century Belgium were subjected to a quantitative and qualitative content analysis. The analysis showed that clear attention was paid to national culinary preferences. In terms of a domestic culinary corpus, it became apparent that both the Dutch and French editions of these cookbooks promoted dishes that were ascribed a Belgian origin. Internationality, however, was also an important building block of Belgian culinary identity. It was part of the desire of Belgian bourgeoisie to connect with an international elite. It fit into the 'search for sophistication', which was also expressed through the high representation of the more costly meats and sweet dishes. In addition, other references associated with bourgeois norms and values, such as family, convenience and frugality, were additional building blocks of Belgian culinary identity. Other issues such as tradition, innovation and health, were also matters of concerns to these Belgian cookbooks.

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

  16. The Diary of Frances Jacobs: Astronomical Observations by a 19th-century Oregon Woman

    This abstract summarizes my research, transcription and editing of Francis Jacob's 170-page handwritten astronomical diary. This diary is a unique example of a time in early Portland history, illustrating the mind of a young woman who was interested in science and astronomy. Reflected in her diary are the discoveries and mention of leading astronomers of the day like Emerson Bernard and Edward Pickering. Francis Jacobs lived in an era of the great refractors For example, ``The Leviathan," built by Lord Rosse in Ireland was completed in 1847. In this 72-inch telescope, stars of 18th magnitude could be seen. The first spiral nebulae to be revealed was M51 - known today as the Whirlpool Galaxy. The Earl was the first to suggest that these spirals could actually be rotating masses of stars. At the turn of the century, study of observational astronomy was rooted in naked eye observing, study of binary stars and nebula. This was a time when women were becoming interested in the sciences and had begun to play an important role in science and astronomy. It was an incredible inspiration for other women across the country to hear what was happening on the astronomical frontiers at Harvard. Some constellation asterisms used in Francis Jacob's diary were different than they are today. One asterism in particular, the Egyptian Cross, is relatively unknown now. The summer triangle and winter circle asterisms were used in her notes and obviously popular in her era, as today. Her written comments included some Messier catalogue numbers and in some case written on her sketches and diagrams nicknames, such as the 'Dumbbell' nebula. She also referred to M99 as `St. Katherine's Wheel', a nickname that is not in common use today.

    Belarus became a Soviet Socialist Republic in the USSR in 1921. Belarus is now an independent country between Poland and Lithuania and Russia. The pharmacy sector of Belarus improved in fits and starts from 1921 to the present but serious quantitative and qualitative problems were evident until the 21st century. A number of factors caused this situation. The Soviet Republic of Belarus started with handicaps. The area, comprised of several provinces of western Russia, had no pharmaceutical factories during the imperial period and, while pharmacies were of high quality in the cities all over the Russian Empire--including Minsk, which became the capital of Belarus--pharmacies were sparse and primitive in rural areas and Belarus was basically rural. Belarus was devastated by wars--World War I, the Russian-Polish war of 1920-21, and of course, by World War II. The Bolshevik policy of nationalizing private pharmacies adversely affected dispensing between 1918 and 1921. Dispensing improved during the New Economic Policy of 1921 to 1927 with re-introduction of private enterprise and the establishment of BelMedTorg and the Mogilev Experimental Station of Medicinal Plants. The number of pharmacies and medical facilities increased during the 1930s and again after World War II. However, utopian plans to provide free or low-cost medicines to all citizens never came to fruition. Inadequate amounts of state-of the-art and even basic medicines persisted through the 1990s. The number of pharmacists also was inadequate and their education and training was on a low level. Because of shortages, citizens of Belarus often self-medicated with medicinal plants. The transition to a market economy in the 1990s made medicines expensive for citizens but opened the door to greater interaction with Western pharmaceutical practices and physical improvements in pharmacies and pharmaceutical production.

    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

    Typhoid fever was the scourge of 19th- and early 20th-century armies. During the Spanish-American War (1898) and the Anglo-Boer War (1899- 1902), typhoid killed more soldiers than enemy bullets. Walter Reed and his coworkers investigated the cause of the typhoid epidemics in the U.S. Army camps and concluded that, next to human contact, the housefly (Musca domestica) was the most active agent in the spread of the disease. British medical officers in South Africa, facing even worse typhoid epidemics, reached the same conclusion. The experiences of the American and British armies finally convinced the medical profession and public health authorities that these insects conveyed typhoid. The housefly was now seen as a health menace. Military and civilian sanitarians waged fly-eradication campaigns that prevented the housefly's access to breeding places (especially human excrement), and that protected food and drink from contamination. Currently, M. domestica is recognized as the mechanical vector of a wide variety of viral, bacterial, and protozoal pathogens. Fly control is still an important public health measure in the 21st century, especially in developing countries.

    The Constitution of the United States is a document for economic development written by people wary of government failure at the extremes, whether too heavy handed a central government or too loose a confederation. The strong central government favored by Hamilton, Industrialists and later by forward thinking men of the 19th century created a discontinuity wherein government institutions designed to facilitate agriculture were incapable of regulating corporations operating on a national scale, which made mineral and other natural resource exploitation needed to support industrialization enormously profitable. At the same time, Agriculturalists and other conservative citizens sought to control the economy by protecting their rural interests and power. The political institutional power remained with states as agriculturalists and industrialists struggled for economic superiority in the 19th century. As Agriculture moved west, Science warned of the dangers of extending Homesteading regulations into arid regions to no avail. The west was settled in townships without concern for watersheds, carrying capacity, or climatic variability. Gold seekers ignored the consequences of massive hydraulic mining techniques. The tension resident in the Constitution between strong local control of government (states' rights) and a strong central government (nationalism) provided no institutional context to resolve mining problems or other 19th century policy problems linked to rapid population expansion and industrialization. Environmental protection in the late 20th century has been the last wave of nationalized policy solutions following the institution-building blueprint provided by electoral successes in the Progressive, New Deal, and Great Society eras. Suddenly in the 21st century, scientific warnings of dangers again go unheeded, this time as evidence of global warming mounts. Again, tension in policy making exists in all political arenas (executive, legislative and judicial at

  1. Two Intense Decades of 19th Century Whaling Precipitated Rapid Decline of Right Whales around New Zealand and East Australia

    Right whales (Eubalaena spp.) were the focus of worldwide whaling activities from the 16th to the 20th century. During the first part of the 19th century, the southern right whale (E. australis) was heavily exploited on whaling grounds around New Zealand (NZ) and east Australia (EA). Here we build upon previous estimates of the total catch of NZ and EA right whales by improving and combining estimates from four different fisheries. Two fisheries have previously been considered: shore-based whaling in bays and ship-based whaling offshore. These were both improved by comparison with primary sources and the American offshore whaling catch record was improved by using a sample of logbooks to produce a more accurate catch record in terms of location and species composition. Two fisheries had not been previously integrated into the NZ and EA catch series: ship-based whaling in bays and whaling in the 20th century. To investigate the previously unaddressed problem of offshore whalers operating in bays, we identified a subset of vessels likely to be operating in bays and read available extant logbooks. This allowed us to estimate the total likely catch from bay-whaling by offshore whalers from the number of vessels seasons and whales killed per season: it ranged from 2,989 to 4,652 whales. The revised total estimate of 53,000 to 58,000 southern right whales killed is a considerable increase on the previous estimate of 26,000, partly because it applies fishery-specific estimates of struck and loss rates. Over 80% of kills were taken between 1830 and 1849, indicating a brief and intensive fishery that resulted in the commercial extinction of southern right whales in NZ and EA in just two decades. This conforms to the global trend of increasingly intense and destructive southern right whale fisheries over time. PMID:24690918

    During the first half of the 19th century, warfare did not provide a background for a systematic analysis of spinal cord injury (SCI). Medical officers participating in the Peninsular and Crimean Wars emphasized the dismal prognosis of this injury, although authors of sketchy civil reports persuaded a few surgeons to operate on closed fractures. The American Medical and Surgical History of the War of the Rebellion was the first text to provide summary of results in 642 cases of gunshot wounds of the spine. The low incidence of this injury (0.26%) and the high mortality rate (55%) discouraged the use of surgery in these cases. Improvements in diagnoses and the introduction of x-ray studies in the latter half of the century enabled Sir G. H. Makins, during the Boer War, to recommend delayed intervention to remove bone or bullet fragments in incomplete injuries. The civil experiences of Elsberg and Frazier in the early 20th century promoted a meticulous approach to treatments, whereas efficient transport of injured soldiers during World War I increased the numbers of survivors. Open large wounds or cerebrospinal fluid leakage, signs of cord compression in recovering patients, delayed clinical deterioration, or intractable pain required surgical exploration. Wartime recommendations for urological and skin care prevented sepsis, and burgeoning pension systems provided specialized longterm rehabilitation. By the Armistice, the effective surgical treatment and postoperative care that had developed through decades of interaction between civil and military medicine helped reduce incidences of morbidity and dispel the hopelessness surrounding the combatant with an SCI.

    In the past, it was customary to use out-of-circulation coins as pendants by brazing a peg or ring on the edge of the coin in order to transform it into a devotional or decorative object; this practice was very common for specimens of the Papal States, especially for silver coins. This metallurgical investigation of a 19th century Scudo aimed to relate the internal structure of the coin to the minting technology with a special focus on the brazing drop, in order to provide information on the solidification microstructure arising from a strongly nonequilibrium process such as brazing. The results show that the Ag content in the coin ranges from 92% in the bulk up to 97% on the surface, due to enrichment, while analysis of the brazing revealed that it consists of an Ag-Cu-Zn-Pb alloy, for which the melting temperature has been estimated. Considering the distribution of minor elements, Zn segregates in the secondary (Cu-rich) β-dendrites and inside the whole eutectic structure, while Pb is only present in the Ag-based phases and seems to reduce the solubility of Zn inside the primary (Ag-rich) α-dendrites.

    When long voyages in sailing vessels were commonplace, scurvy was a major health hazard in mariners of all nations. The observations of James Lind (1716-94) and others indicated that citrus fruits had both a preventive and curative role in this disease. In the light of this work, by 1800 the disease had been virtually eliminated from Britain's Royal Navy. However, it continued in the merchant navies of all nations until the latter half of the 19th century. In 1867, the Merchant Shipping Amendment Act was passed by the British Parliament largely as a result of a concerted effort by the Seamen's Hospital Society (SHS), one of whose physicians, Harry Leach (1836-79) was the major proselytiser for improved conditions in the merchant service. Examination of the SHS records before and after this event demonstrate a marked reduction in the prevalence of scurvy in the Port of London. Although other factors-such as the introduction of steam ships, which resulted in faster voyages-were clearly important, the compulsory administration of genuine lime juice under supervision in the merchant service seems to have exerted a significant effect.

    Mitigation of climate change and adaptation to its effects relies partly on how effectively land-atmosphere interactions can be quantified. Quantifying composition of past forest ecosystems can help understand processes governing forest dynamics in a changing world. Fossil pollen data provide information about past forest composition, but rigorous interpretation requires development of pollen-vegetation models (PVMs) that account for interspecific differences in pollen production and dispersal. Widespread and intensified land-use over the 19th and 20th centuries may have altered pollen-vegetation relationships. Here we use STEPPS, a Bayesian hierarchical spatial PVM, to estimate key process parameters and associated uncertainties in the pollen-vegetation relationship. We apply alternate dispersal kernels, and calibrate STEPPS using a newly developed Euro-American settlement-era calibration data set constructed from Public Land Survey data and fossil pollen samples matched to the settlement-era using expert elicitation. Models based on the inverse power-law dispersal kernel outperformed those based on the Gaussian dispersal kernel, indicating that pollen dispersal kernels are fat tailed. Pine and birch have the highest pollen productivities. Pollen productivity and dispersal estimates are generally consistent with previous understanding from modern data sets, although source area estimates are larger. Tests of model predictions demonstrate the ability of STEPPS to predict regional compositional patterns.

    The German psychologist Theodor Waitz (1821-1864) was an important theorist of affectivity in the mid-19th century. This article aims to revisit Waitz's contribution to affective psychology at a crucial moment of its history. First, I elaborate the context in which Waitz's ideas were carried out by showing how affective sciences emerged as an autonomous field of investigation between about 1770 and 1910. Second, I discuss the principles of Waitz's model of affectivity and their contextual significance. Third, I deal with the first major category of affective states identified by Waitz, namely, "formal feelings," which are supposed to be involved in the appraisal of the relational properties between representations. Fourth, I investigate "qualitative feelings," the second major category of affective states identified by Waitz, which refer to affective processes that relate to specific representational contents, namely, intellectual, aesthetic, and moral feelings. In conclusion, I emphasize the genealogical link between Waitz's pioneering research on musical feelings and current research on emotion and expectation in music.

    This study examines the social devaluation of the knowledge and practice used by midwives in their work. The research is limited to historical events that took place during the 19th century in the city of Guadalajara, capital of the state of Jalisco in Mexico. The study shows how the displacement and subordination of these women were associated with the higher social status of physicians. Supported by advances in medicine and by the authority derived from the knowledge acquired through formal educational institutions, doctors started to undermine the value of empirical knowledge and subordinate it to the knowledge that came from these advances. It is shown how doctors detract from and subordinated the midwife to the scientific-employment field of medicine by using a discourse that degraded empirical knowledge and by institutionalizing training courses that tended to ignore the practical know-how of these women and replace it with knowledge derived from scientific medicine. The study is based on information from archives and scientific journals of the time: Archiva Fondos Especiales de la Biblioteca Pública de Jalisco, Archivo Histórico de Jalisco, Archivo Histórico de la Universidad de Guadalajara, Archivo Municipal de Guadalajara and Revista Médica.

    In August 2009, we conducted an underwater geophysical survey with archaeological objectives at the Tequesquitengo Lake, in Morelos, Mexico. This survey was supervised by researchers from the UNAM’s Institute of Geophysics. The main objectives were to locate and delimitate the archaeological site of a submerged town which lies at the bottom of the lake since the mid 19th century by using geophysical survey techniques. A small size vessel used for our survey was provided by the local Harbour Master, onboard which we mounted a differential GPS unit, navigation system, a dual 38 kHz/200 Khz echosounder and 200 kHz sidescan sonar system, and a marine proton magnetometer, to accomplish our objectives. A bathymetric survey of the site was carried out. And using magnetometry the archaeological site was delimitated. We acquired various sonar images of the higher structures of a church. The magnetic maps showed us some anomalies, which could be an indication of the remains of the submerged town. Additional future surveys, backed up by more research dives could definitely help us in obtaining a broad insight into the history and cultural diversity of this site.

  1. The "Abyssal Society". François-Alphonse Forel and the Case of Deep Fauna in Late 19th Century.

    PubMed

    Campanella, Sara

    2016-01-01

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

    2009-01-01

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

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

    Early instrumental series are the main source for climate information in the 18th and the first part of the 19th century, which is when systematic meteorological observations started in most national meteorological services. The first continuous series in Spain starts in 1780 in Barcelona due to meteorological observations made by the medical doctor Francisco Salvá Campillo. Moreover, only two other series have been recovered at the present in Spain: Madrid and Cádiz/San Fernando. Until present, in Spain the major part of the meteorological observations detected in early instrumental periods were made by medical doctors, who started to pay attention to the environmental factors influencing population health under the Hippocrates oath, although also there are military institutions and academic university staff (e.g. physicists, mathematicians, etc.). Due to the high spatial and temporal climate variability in the Iberian Peninsula, it is important to recover and digitize more climatic series, and this is one of the main goals of the Salvá-Sinobas project (http://salva-sinobas.uvigo.es/) funded by the Spanish Ministry of Environment, and Rural and Marine Affairs for the 2009-2011 period. The first new series with systematic observations was detected in the city of Valencia, in the eastern façade of the Iberian Peninsula. The meteorological observations were daily published in the newspapers Diario de Valencia (1804-1834) and Diario Mercantil de Valencia (1837-1863) until official meteorological observations started in 1858 at the University of Valencia. Each day 3-daily observations (morning, midday, afternoon) were published with five climatic variables: temperature, air pressure, humidity, wind direction and the sky state. Only during the 1804-1808 period daily rainfall data is available. We checked the observer comments published in the newspapers to obtain metadata about the instruments and meteorological station information. Unfortunately, temperature data

    Rainfall patterns in Southern California directly affect the availability of water resources and induce hazards in this highly populated and water stressed region. Extreme weather consists of heavy rainfall events in winter associated with atmospheric rivers, and drought conditions when winter rains do not arrive. Water availability has a significant societal impact in Southern California. Here we reconstruct 19th-20th century precipitation history of river catchments draining into Santa Barbara Basin (SBB) through a combination of high-resolution elemental and mineralogical analyses. The deep center of the SBB features suboxic bottom waters and high sedimentation rates resulting in minimal bioturbation of annual sedimentation, which enables high-resolution paleoclimate research. Scanning XRF analysis at a 200 μm resolution of box core SPR0901-04BC from SBB was used to determine annual changes in sediment composition. Samples at 1 cm resolution from the same box core were analyzed for a more extensive suite of elements by ICP-MS, while mineralogy in each sample was determined from whole rock and clay fraction (<2 μm) analysis using X-ray defraction. Elements associated with siliciclastic sediment increase in relative abundance during wet years when significant river runoff events (floods) occurred. The relative proportions of these elements differ between flood events, possibly reflecting differences in temporal and/or spatial rainfall patterns that vary the response of each river catchment draining into SBB. Watershed sediment from the Santa Ynez Mountain streams and Ventura and Santa Clara River catchments derives mostly from Cenozoic sedimentary units, except the Santa Clara River catchment, which contains metamorphic and igneous units. As river runoff is responsible for a significant portion of the terrigenous input into SBB, and is primarily the result of precipitation events, characteristic mineralogy and elemental signatures are a direct recorder of

    Different documentary evidence (taxation records, chronicles, insurance reports etc.) is used for reconstruction of hydrometeorological extremes (HMEs) in the Jihlava region (central part of the recent Czech Republic) in the 17th-19th centuries. The aim of the study is description of the system of tax alleviation in Moravia, presentation of utilization of early fire and hail damage insurance claims and application of the new methodological approaches for the analysis of HMEs impacts. During the period studied more than 400 HMEs were analysed for the 16 estates (past basic economic units). Late frost on 16 May 1662 on the Nove Mesto na Morave estate, which destroyed whole cereals and caused damage in the forests, is the first recorded extreme event. Downpours causing flash floods and hailstorms are the most frequently recorded natural disasters. Moreover, floods, droughts, windstorms, blizzards, late frosts and lightning strikes starting fires caused enormous damage as well. The impacts of HMEs are classified into three categories: impacts on agricultural production, material property and the socio-economic impacts. Natural disasters became the reasons of losses of human lives, property, supplies and farming equipment. HMEs caused damage to fields and meadows, depletion of livestock and triggered the secondary consequences as lack of seeds and finance, high prices, indebtedness, poverty and deterioration in field fertility. The results are discussed with respect to uncertainties associated with documentary evidences and their spatiotemporal distribution. Archival records, preserved in the Moravian Land Archives in Brno and other district archives, create a unique source of data contributing to the better understanding of extreme events and their impacts.

    Diaphanoscopy/transillumination, the method of shining a bright light through tissues, was devised in the mid-19(th) century and developed after the invention of the light bulb by T.A. Edison. Benjamin Milliot was the first to examine the stomach by means of an incandescent platinum wire. The experiments conducted by Max Einhorn using a device consisting of a Nelaton catheter with an inserted light bulb, were valuable. In Poland the method of gastrodiaphanoscopy was popularized by Teodor Heryng, Mikołaj Rejchman and by Warsaw doctors. They used a diaphanoscope consisting of a gutta-percha probe distally equipped with a metal attachment with a light bulb hidden in it and with a so-called cooling device. The examination would usually be conducted in the standing position after the stomach had been filled with water. Light patches corresponding to the stomach's lower and side boundaries would be obtained. Rejchman's observation, that such a contractile and flexible organ as the stomach, changing its volume and position, is bound to change its light image, was correct. Heryng's and Rejchman's research inspired the foreign researchers Renvier, Leopold Kuttner and John Jacobson. Extensive research was subsequently conducted by C.A. Meltzing and Wilhelm Schwartz. Diaphanoscopy would also be performed by Walery Jaworski, the pioneer of gastrology. He was particularly interested in transillumination of the stomach, peritoneum and omentum tumours.

    Leprosy was highly prevalent among African slaves in the Dutch West Indian colony of Suriname. Largely based on observations in Suriname, Dutch physicians described the aetiology of leprosy in terms of'a substrate' to which all sorts of mixtures of infection, heredity and hygiene contributed ('seed and soil'). This explanatory model with multiple options for prevention and treatment left room for different developmental trajectories to control the spread of the disease in the various tropical colonies of the Dutch empire. In Suriname there was a growing worry in the 19th century regarding the spread of leprosy, threatening the health of slaves, settlers and colonial administrators. And this could be harmful to an already weakening plantation economy. This concern prompted the local administration to develop a rigorous policy of strict isolation of leprosy sufferers. This, in turn, intersected with a changing insight in Europe - including the Netherlands - that leprosy was non-contagious. However,'in splendid isolation' in the economically and politically marginal colony Suriname, Dutch physicians like Charles Landre and his son, Charles Louis Drognat Landré, could afford to ignore the European non-contagious approach and continue to support the strict isolation policies. Moreover, they developed a dissident radical explanation of leprosy as a disease caused only by contagion. In the absence of a receptive Dutch audience Drognat Landré published his contagion theory in French and so succeeded in inspiring the Norwegian Hansen, who subsequently discovered the culpable micro-organism. At the same time colonial administrators and physicians in the economically and politically important Dutch colonies in the East Indies adhered to the prevailing European concept and changed policies: the system of isolation was abolished. Given the rather different trajectories of leprosy health policies in the Dutch East and West Indies we point out the importance of a comparative

    The plague epidemic that has occurred in Bombay at the end of the 19th century was detected in 1896. One year before, an Advisory Committee had been appointed by the Secretary of State for India, the Royal Society, and the Lister Institute. This Committee made numerous investigations and gathered a large panel of data including the number of people attacked and died from the plague, records of rat and flea populations, as well as meteorological records of temperature and humidity [1]. The global modeling technique [2] aims to obtain low dimensional models able to simulate the observed cycles from time series. As far as we know, this technique has been tried only to one case of epidemiological analysis (the whooping cough infection) based on a discrete formulation [3]. In the present work, the continuous time formulation of this technique is used to analyze the time evolution of the plague epidemic from this data set. One low dimensional model (three variables) is obtained exhibiting a limit cycle of period-5. A chaotic behavior could be derived from this model by tuning the model parameters. It provides a strong argument for a dynamical behavior that can be approximated by low dimensional deterministic equations. This model also provides an empirical argument for chaos in epidemics.

    Geodiversity is the natural and cultural range of geological, geomorphological and soil features. We analysed the large database of 19th and early 20th century paintings of Simonis and Buunk (www.Simonis-Buunk.com) to track changes in the geodiversity of Dutch peatlands since pre-photographic times. Peat dominated in two of the eight main landscapes of the Netherlands: the Lowland peats in the Holocene west and the Highland peats in the sandy Pleistocene eastern parts. Painters were mainly attracted by the lowland peats. Since more than thousand years, peat plays a major role in Dutch military security, economy, ecology and cultural life. Natural variety and cultural use resulted in a geodiversity that is unique in Europe. There are more than 100 place names with 'veen' (= peat), and surnames with 'veen' are common. Proof of the exploitation of peat for salt and fuel exists from the Roman times onwards. In the 9th century, peatlands were drained and reclaimed for growing wheat. Already in the 11th century, it was necessary to build dikes to prevent flooding, to control waterlevels to avoid further oxidation, and to convert landuse to grassland. But subsidence continued, and in the 14th century windmills were needed to drain the lands and pump the water out. In the 16th century industrial peat exploitation fuelled the rise of industries and cities. All this draining and digging caused the peat surface to shrink. The few remaining living peats are conserved by nature organisations. Geodiversity and landscape paintings In the peat landscapes, popular painting motives were high water levels, the grasslands of the 'Green Heart', the winding streams and remaining lakes. The paintings of landscapes where peat had been removed, show watermanagement adaptations: wind mills, different water levels, canals made for the transport of fuel, bridges, tow paths and the 'plassen', i.e. the lakes left after peat exploitation.

    When we make a study of past climatic variations, it would be preferable to get as long instrumental records as possible. In Japan, however, the earliest official meteorological observations by JMA (Japan Meteorological Agency) started at Hakodate in 1872, since which only 128 years have passed. Prior to that period, there was no official instrumental record in Japan. Recently, we could fortunately get information that several instrumental observations were taken under the responsibility of the Dutch in Dejima (Nagasaki) covering the periods 1819-1828, 1845-1858 and 1871-1878. As Nagasaki meteorological observatory was established in 1878, these Dutch instrumental series could be connected with the instrumental Nagasaki observatory series (1878-present). Although a lot of benefits are available in using long-term meteorological data for a study of climatic variations, there are some problems to be solved beforehand, such as inhomogeneity between historical data and modern data. In response to this fact mentioned above, we made the study of 1) making the database of Dejima/Nagasaki meteorological records for 180 years since 1819; 2) homogenizing monthly mean temperatures; 3) analyzing climate evolution in Nagasaki since early 19th century; and 4) developing and constructing the method for homogenizing daily mean temperatures. Firstly, in order to make the data base of Dejima/Nagasaki records, all meteorological elements (temperature, pressure, humidity, wind and precipitation) in Dutch records were converted to the same units as the present ones and digitized into the computer readable form. Secondly, inhomogenized monthly mean temperature data were completed by applying the mean calculation and height correction method, and the Jones et al. (1986) method. The latter method would be reasonable compared to the former method. Thirdly, climate variability of homogenized monthly mean temperature in Nagasaki was analyzed by comparing to the estimated temperatures from

    Few areas in Iceland were as vulnerable to climate changes during the 19th century as the region south of Vatnajökull glacier. The region was repeatedly affected by glacier advance and jökulhlaups (glacier outburst floods) during the Little Ice Age AD 1300-1900 (LIA). The land area between the glacier and the coast was occupied by farming community. The aim of this research is to quantify and map the size of lost vegetated area in the 19th century during the glacial advance in the climax of the LIA and the impact these events had on the community, land-use, ownership, value of estates and livelihood. This research employs historical written sources to investigate changes in the cultural and natural landscape. Historical data and field observations will be collected and stored in a GIS database designed for the research, allowing data to be analyzed and presented on maps. The first recorded impact on the settlement is from 1794 when the Breiðármerkurjökull outlet glacier advanced and devastated pastures and crofts belonging in west of the district. Seventy five years later, in 1868, the largest estate was completely destroyed by a jökulhlaup. In 1829 a farm site in the middle of the district was moved due to repeated jökulhlaup. The outlet glacier Brókarjökull initiated annual jökulhlaups during 1820 -1870, devastating pastures and hayfields and woodlands of a total of 3 prominent estates in the area (by 1200 ha), causing devaluation of 33-66% on these estates. In the eastern part extensive jökulhlaups changed the glacial river channel causing the river to flow over vast area devastating 80 % of the eastern most estate causing its abandonment in 1892. The climate change and accompanied hazards during the 19th century changed the landscape of the Suðursveit district significantly. By the turn of the 20thcentury the vegetated land in the district had been reduced by 35% and areas of sediments increased by 25% and glaciated area increased by 10%. These

    Criminal psychology emerges at the end of the 18th century as a new academic discipline in lectures and publications. It has recently been investigated by a considerable number of contributions from researchers of different academic backgrounds. In many respects criminal psychology can be seen as a predecessor of criminology. Its subject is the analysis of the origins of crime and its causes and determinants in the human mind. Criminal psychology embraced at that time philosophical, medical, legal and biological aspects. The latter increase in importance in the second half of the 19th century. The conditions of individual responsibility were generally codified in penal law, but had to be individually investigated in crucial cases through expertise in court. There a conflict emerged between medical experts and judges about their ability and competence to decide. At the end of the 19th century criminal psychology is used to fulfil the needs and interests of a criminal law which understands itself as increasingly utilitarian. Force and new instruments of treatment of offenders were legitimized by scientists who were very optimistic about their own epistemological abilities.

    The lead isotopic composition of various sections (crown, crown base, root) of teeth was determined in specimens collected from 19th century skulls preserved in museum collections and, upon extraction or exfoliation, from humans of known ages residing in Scotland in the 1990s. For most 20th century samples, calculation of accurate crown-complete or root-complete dates of tooth formation ranging from the 1920s to the 1990s enabled comparison of (206)Pb/(207)Pb ratios for teeth sections (crown base root) with corresponding decadally averaged data for archival herbarium Sphagnum moss samples. This showed that the teeth sections had been significantly influenced by incorporation of non-contemporaneous (more recent) lead subsequent to the time of tooth formation, most probably via continuous uptake by dentine. This finding confirmed that separation of enamel from dentine is necessary for the potential of teeth sections as historical biomonitors of environmental (and dietary) lead exposure at the time of tooth formation to be realised. Nevertheless, the mean 19th century value of 1.172+/-0.007 for the (206)Pb/(207)Pb ratio in teeth was very similar to the corresponding mean value of 1.173+/-0.004 for 19th century archival moss, although relative contributions from environmental sources - whether direct, by inhalation/ingestion of dust contaminated by local lead smelting ((206)Pb/(207)Pb~1.17) and coal combustion ((206)Pb/(207)Pb~1.18) emissions, or indirect, through ingestion of similarly contaminated food - and drinking/cooking water contaminated by lead pipes of local origin, cannot readily be determined. In the 20th century, however, the much lower values of the (206)Pb/(207)Pb ratio (range 1.100-1.166, mean 1.126+/-0.013, median 1.124) for the teeth collected from various age groups in the 1990s reflect the significant influence of imported Australian lead of lower (206)Pb/(207)Pb ratio (~1.04) and released to the environment most notably through car

    In the 19th century, descriptions of patients with disorders of higher cerebral functions were typically presented in a mixed series of children, adolescents, adults, and the elderly. There was no indication in the analysis or interpretation that age was thought to play a role in the signs or symptoms displayed, or in the prognosis. The role of age in the manifestation of language disorders only became explicit in the late 19th century in the elaboration of ideas regarding perinatal illnesses, developmental difficulties, and the emerging clinical category of "cerebral palsy" as evinced in the work of Bastian, Osler, Sachs and Peterson, and Freud. Their patient series studies afforded the opportunity to identify relations between age at symptom onset and patterns of language acquisition and impairment. These analyses contributed directly to the elaboration of hypotheses regarding localization of function, hemispheric specialization, and patterns of recovery. The factor of "age at symptom onset" would steadily assume even greater theoretical importance, as explanations of patterns of symptom co-occurrence, etiology, and prognosis were elaborated through the increasing appreciation of a developmental/maturational perspective.

    Many species are threatened with extinction and efforts are underway worldwide to restore imperilled species to their native ranges. Restoration requires knowledge of species' historical diversity and distribution. For some species, many populations were extirpated or individuals moved beyond their native range before native diversity and distribution were documented, resulting in a lack of accurate information for establishing restoration goals. Moreover, traditional taxonomic assessments often failed to accurately capture phylogenetic diversity. We illustrate a general approach for estimating regional native diversity and distribution for cutthroat trout in the Southern Rocky Mountains. We assembled a large archive of historical records documenting human-mediated change in the distribution of cutthroat trout (Oncorhynchus clarkii) and combined these data with phylogenetic analysis of 19th century samples from museums collected prior to trout stocking activities and contemporary DNA samples. Our study of the trout in the Southern Rocky Mountains uncovered six divergent lineages, two of which went extinct, probably in the early 20th century. A third lineage, previously declared extinct, was discovered surviving in a single stream outside of its native range. Comparison of the historical and modern distributions with stocking records revealed that the current distribution of trout largely reflects intensive stocking early in the late 19th and early 20th century from two phylogenetically and geographically distinct sources. Our documentation of recent extinctions, undescribed lineages, errors in taxonomy and dramatic range changes induced by human movement of fish underscores the importance of the historical record when developing and implementing conservation plans for threatened and endangered species.

    A fall in the age of menarche during the last fifty years is well documented from many parts of the world, among them Norway. Tanner says that this trend can be extended back at least to the middle of the last century, and he uses Norwegian sources to support this hypothesis. Re-examination of these Norwegian sources indicates that there was no fall at all during the ninetheenth century, and that the age at menarche was constant at approximately 16.0 years for the lower social classes throughout this period. It is also suggested that the age at menarche was constant at approximately 14 years for the higher social classes.

    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.

    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.

    This is an historical and descriptive account of 28 herbarium specimens, 27 lichens and an alga, found in the archives of Charles Chalcraft, a descendant of the Bedford family, who were dye manufacturers in Leeds, England, in the 19th century. The lichens comprise 13 different morphotypes collected in the Canary Islands and West Africa by the French botanist J. M. Despréaux between 1833 and 1839. The collections include samples of "Roccella fuciformis", "R. phycopsis" and "R. tinctoria" (including the fertile morphotype "R. canariensis"), "Ramalina crispatula" and "R. cupularis", two distinct morphotypes of "Sticta", "S. canariensis" and "S. dufouri", "Physconia enteroxantha", "Pseudevernia furfuracea var. ceratea" and "Pseudocyphellaria argyracea". The herbarium also includes authentic material of "Parmotrema tinctorum" and a probable syntype of "Seirophora scorigena". Most of these species are known as a source of the purple dye orchil, which was used to dye silk and wool.

  8. Widow and widower remarriage: an analysis in a rural 19th century Costa Rican population and a cross-cultural discussion.

    Although the topic of remarriage features saliently in the cultural anthropological literature, it is virtually absent in the biological anthropology journals. This is perplexing, given that remarriage affects the differential reproductive success of males and females in a community, and could well impact a community's population structure. In this paper, we research remarriage practices in a rural 19th century community in Costa Rica. Although we find support for the proposition that males are more likely to remarry than females, we find that widows who remarry are not all young and able to reproduce. Our findings support the cross-culturally-generated suggestion that a female's ability not to remarry is tied to her to ability to own property. Remarriage is a topic of interest to biological anthropologists from a cross-cultural and biocultural perspective.

    Ground-penetrating radar (GPR) is a geophysical survey tool with many archaeological applications, including the search for graves. A 400 megahertz GPR was employed to locate unmarked graves and buried headstones in a neglected Pennsylvania cemetery dating from the 19th century. The site was initially scanned using a grid pattern with 50cm transect spacings. A smaller site within the cemetery was then selected and scanned at a higher 'resolution,' using smaller transect spacings, to determine whether this improved the accuracy of the findings. Supplementary perpendicular transects were also added. A number of potential sources of error were identified and their consequences were outlined. Short transects with small spacings were found to significantly improve the quality of the obtained data, as was the addition of perpendicular transects. The results are applicable to the search for graves and, more broadly, the use of GPR to identify and locate other subsurface features.

    The insanity defence has a lengthy, complex history. This article provides a concise, comparative background to the evolution of criminal insanity legislation and institutions for the mentally ill in the nineteenth century, with particular reference to Ireland and the United States. Three key themes are identified and explored: (a) the emergence of the insanity defence in the nineteenth century (e.g. the McNaughtan Rules); (b) conditions in nineteenth-century asylums and institutions for the 'criminally insane' (with particular reference to overcrowding, physical illness and asylum deaths); and (c) nineteenth-century considerations of criminal responsibility in women with mental illness (with particular reference to medical and judicial views of the relevance of menstruation, pregnancy and child-birth). These themes are explored through review of historical literature (with particular reference to the work of Dr. Isaac Ray, founding father of forensic psychiatry in the United States) and examination of previously unpublished archival material from the Central Criminal Lunatic Asylum, Dublin.

    Freshwater plays a critical role in preserving the biological and hydrological functions of the terrestrial ecosystems that sustain civilization. Hydrologic processes shape the distribution, structure, and dynamics of biological systems, while the feedbacks from biological systems impact the hydrologic cycle. Climate is the main driver that adds dynamics to the hydrologic cycle. In order to identify the changes and variability in the Northeast region’s climate and to understand their impacts on the hydrological cycle, we are conducting an assessment of the region’s climate. Annual and monthly time series of precipitation and temperature data collected for one hundred locations in the region, spanning from Maine to Virginia, during the period 1800 to 1920 are analyzed to assess the spatial and temporal variations in climate. It has been reported that the region’s climate during the 19th century is largely modulated by climatic oceanicity and the sunspot rhythm, and, that human influence did not have significant impact on the regional climate. Our preliminary findings do not show significant variations in the mean annual climate, but show variations in intra-annual climate, particularly monthly precipitation. Based on the review of historical documents, the intra-annual variation in precipitation was a concern of water resource planners during the 19th century. The present research attempts to bring out linkages between spatial and temporal variations in the regional climate and water availability. Additional information on land cover, measured and modeled runoff for a selected location will be used as case study to highlight climate variability and its impact on water availability.

    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.

    2010-01-01

    This paper studies the attitude of the society towards the medical profession, which was torn between high social expectations and ideals and medical practice confronted with real-life obstacles. In the 19th century, the physician's position was still precarious and called for a renegotiation in the community. Physician's work was faced with people's distrust and resistance, superstitions and prejudices, folk medicine and religion. Even such ideal qualities as dignity, conscientiousness, and courage, would quickly be called into question by events such as epidemics. Particularly in 19th century rural areas, the physician's position was far from acknowledged and official medicine had yet to win people's trust. This paper explores the polyvalent attitude of people towards medicine and health. It investigates the discourse used to describe health and medicine in daily press, professional and popular literature, as well as in official medical documents of the time. It shows a long struggle of public health care to gain people's approval. During cholera epidemics, which apart from presenting serious threat to human life were an opportunity for medicine to win people's trust and obedience, the attitude towards health gradually began to change. To some extent this was a result of medical advances, new scientific discoveries, and increasing success in abating the epidemics. At the same time, as the society became more secular, medicine slowly gained people's trust and gradually replaced the healing methods of folk medicine. Health was less and less understood as a result of God's will and mercy, and the attitude towards disease began to evolve from passive resignation to an active battle for health.

    In the 19th century, the British polecat suffered a demographic contraction, as a consequence of direct persecution, reaching its lowest population in the years that preceded the First World War. The polecat is now recovering and expanding throughout Britain, but introgressive hybridization with feral ferrets has been reported, which could be masking the true range of the polecat and introducing domestic genes into the species. We used a fragment of the mitochondrial DNA control region and 11 microsatellite loci to characterize the frequency and extent of hybridization and introgression between the two species and assess whether the 19th-century decline corresponded to a genetic bottleneck in the polecat. The proportion of admixture detected in the wild was high (31%) and hybrids were more frequently found outside Wales, suggesting that hybridization is more likely to occur along the eastern edge of the polecat's range expansion. The patterns observed in the mitochondrial and nuclear DNA data show that introgression was mediated by crosses between male polecats and female ferrets, whose offspring backcrossed with polecats. No first-generation (F1 ) hybrids were identified, and the broad range of observed admixture proportions agrees with a scenario of past extensive hybridization between the two species. Using several different methods to investigate demographic history, we did not find consistent evidence for a genetic bottleneck in the British polecat, a result that could be interpreted as a consequence of hybridization with ferrets. Our results highlight the importance of the Welsh polecat population for the conservation and restoration of the genetic identity of the British polecat.

  15. From sermons in stone to studies in science: The transformation of 19th-century juvenile natural history

    Dyson, Jon-Paul Charles

    This dissertation seeks to explain the social, cultural, and economic factors that transformed the ways nineteenth-century American children learned about, encountered, and understood the natural world. It highlights the interests, tastes, and fears of the middle-class as key factors in the transformation of children's relationship to nature. Developments such as the quest for gentility and refinement, the evolution of religious practices and beliefs, the print revolution, the popularity of Romanticism, the marginalization of women, the rise of professionalization, the impact of industrialization, and the growth of cities all helped shape nineteenth-century children's relationship to nature. For much of the seventeenth and eighteenth centuries adults had taught children to see nature as a world of wonders in which God acted out his Providential design. During the early republic, however, Americans, especially women, increasingly valued more refined and genteel interpretations of nature that invoked discrete segments of nature for their ability to cultivate morals, evidence the existence of God, and mold children's behavior. The print revolution that swept America during this period abetted this process. During the second quarter of the nineteenth century, increasing numbers of adults began to use religious publications, schoolbooks, literature, and domestic amusements to involve children with the natural world in ways that were variously religious or Romantic. As a result nature became an accepted and valued segment of middle-class life. Ironically, however, these efforts also helped separate religious from secular interpretations of nature, and changes in fashions, literary techniques, and parenting techniques allowed children more autonomy to interpret nature as they wished. In the last half of the nineteenth century, adults continued to rely on nature as a means of training up children in the ways they should go. Writers, teachers, and reformers increasingly

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

    East African elephants have been hunted for their ivory for millennia but the nineteenth century witnessed strongly escalating demand from Europe and North America. It has been suggested that one consequence was that by the 1880s elephant herds along the coast had become scarce, and to meet demand, trade caravans trekked farther into interior regions of East Africa, extending the extraction frontier. The steady decimation of elephant populations coupled with the extension of trade networks have also been claimed to have triggered significant ecological and socio-economic changes that left lasting legacies across the region. To explore the feasibility of using an isotopic approach to uncover a ‘moving frontier’ of elephant extraction, we constructed a baseline isotope data set (δ13C, δ15N, δ18O and 87Sr/86Sr) for historic East African elephants known to have come from three distinct regions (coastal, Rift Valley, and inland Lakes). Using the isotope results with other climate data and geographical mapping tools, it was possible to characterise elephants from different habitats across the region. This baseline data set was then used to provenance elephant ivory of unknown geographical provenance that was exported from East Africa during the late nineteenth and early twentieth centuries to determine its likely origin. This produced a better understanding of historic elephant geography in the region, and the data have the potential to be used to provenance older archaeological ivories, and to inform contemporary elephant conservation strategies.

    The New World was ravaged by smallpox for several centuries after the Spanish conquest. Jenner's discovery of the smallpox vaccine made possible the prevention and control of smallpox epidemics. In response to a large outbreak of smallpox in the Spanish colonies, King Charles IV appointed Francisco Xavier de Balmis to lead an expedition that would introduce Jenner's vaccine to these colonies. During the journey, the vaccine was kept viable by passing it from arm to arm in orphaned children, who were brought along expressly for that purpose and remained under the care of the orphanage's director. This expedition was the first large scale mass vaccination of its kind. The historic legacy of this pioneering event in international health should be revisited in the current era of persistent inequalities in global health.

    By the beginning of the 16th century, the Portuguese State imposed on local powers the obligation to bring up and take care of foundlings. However, with the creation of the Misericórdia fraternities all over the country, the municipalities transferred the assistance of the children to those charities, with the promise of economic support. Nonetheless, in spite of the State "interest", the concern of local powers and the care provided by the Misericórdias, the results were tragic for the children. In this paper I intend to provide a summary about the welfare services for foundlings in Portugal, and to study the assistance that was given to them in the city of Evora.

The goal of this study was to evaluate a marsh-to-mangrove conversion spanning 125 years and the implications for present coastal-resource management (Yates and others, 2011; Raabe and others, 2012). The U.S. Geological Survey in St. Petersburg, Fla., georectified and digitized 1870s T-sheets at four Tampa Bay locations that still supported coastal wetlands in 2000 (table 1). Nineteenth century Public Land Surveys of Township and Range lines were also digitized for each site, as a secondary data source to verify historic landscape features (table 2).

    Medicine in the second half of the nineteenth century takes on some characteristics of modernity. These characteristics are worthy of our attention because they help us to understand better some of the current problems of hygiene and public health. One of the topics that was most discussed in the scientific-academic milieu of the second half of the nineteenth century was cremation. There was a poetic precedent: the cremation of Percy Bysse Shelley (1792-1822). The earliest apparatus to completely destroy the corpse was made in Italy and Germany in the 1870s. As far as hygiene was concerned, the reasons for cremation were not to pollute the water-bearing strata and an attempt to streamline the cemetery structure. As in an apparent schizophrenia, scientists of the day worked to both destroy and preserve corpses. There is also the unusual paradox that when the first cremations took place, the corpses were first preserved then to be destroyed later. The catholic world (mainly in Italy) and forensic scientists opposed cremation. It was left to the hygienists to spread the practice of cremation. An analysis of scientific literature shows us that if we leave out the related forensic and ethical problems, recent years have seen attention paid to any harmful emissions from crematoria equipment which have poured into the environment. Another issue is the assessment of inadvertent damage which may be caused by the condition of the corpse. Some topics, however, such as the need for preventive autopsies (first proposed in 1884 in Milan) are still a subject of debate, and seem to pass virtually unchanged from one generation to the next.

    The exhumed remains of 181 people, buried during the period 1848-1984 were examined. Because of the carelessness of exhumations, only 125 yielded sufficient information to compare the condition of skulls and jaws with the period in the grave, while 63 yielded information about the teeth. No correlation could be shown between the condition of the skulls and jaws and the period interred, but it was found that the better preserved remains belonged to younger people. Dental findings included the presence of healthy and decayed teeth, gold foil restorations, gold and porcelain inlays, amalgam and silicate fillings, and vulcanite and acrylic dentures. Amalgam restorations were present in people buried from 1875 (114 years ago) and vulcanite dentures from 1882 (107 years ago). The characteristics of the earliest amalgam restorations showed that they could have been placed before 1850. Findings of this study indicate that: (a) one cannot on the appearance of exhumed remains estimate the burial period, (b) dental features were well preserved and can be used for dental identification if antimortem data are available, (c) advanced dentistry could have been practised in South Africa during the last century, and (d) recovery of human skeletal remains from old cemeteries should be undertaken with care to preserve as much information as possible. A plea is made for closer co-operation between developers of old graveyard sites and scientists in order to preserve as much information as possible.

    A cache feature salvaged from an eroding sea cliff on San Nicolas Island produced two redwood boxes containing more than 200 artifacts of Nicoleño, Native Alaskan, and Euro-American origin. Outside the boxes were four asphaltum-coated baskets, abalone shells, a sandstone dish, and a hafted stone knife. The boxes, made from split redwood planks, contained a variety of artifacts and numerous unmodified bones and teeth from marine mammals, fish, birds, and large land mammals. Nicoleño-style artifacts include 11 knives with redwood handles and stone blades, stone projectile points, steatite ornaments and effigies, a carved stone pipe, abraders and burnishing stones, bird bone whistles, bone and shell pendants, abalone shell dishes, and two unusual barbed shell fishhooks. Artifacts of Native Alaskan style include four bone toggling harpoons, two unilaterally barbed bone harpoon heads, bone harpoon fore-shafts, a ground slate blade, and an adze blade. Objects of Euro-American origin or materials include a brass button, metal harpoon blades, and ten flaked glass bifaces. The contents of the cache feature, dating to the early-to-mid nineteenth century, provide an extraordinary window on a time of European expansion and global economic development that created unique cultural interactions and social transformations.

    The generative relationship between text and image has long been established. Its structure evolved historically as a result of varying understandings of the functions of art and technology. Agriculture illustration, which emerged in China during the Song dynasty, is a prime example of this creative dialogue in which aspects of both disciplines were combined. Political, technological, and aesthetic concerns informed the reformulations of this new genre. This paper will address agricultural illustrations on nineteenth-century Korea, when notable changes occurred in the visualization of agricultural texts. It will explore changes in the understanding of the roles of agriculture, technology, and labor through an analysis of shifts in modes of illustration and the texts selected. The relationship between technology and visual representations during late Joseon Korea will be contextualized through an exploration of the evolution of technical drawing in East Asia. This paper will suggest that the recognition of imagery's ability to convey textual and technical information provided an important alternative paradigm for the presentation and use of knowledge.

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

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

    At the end of the Little Ice Age an increase in flood frequency and impacts was produced in the Southwest of Europe. In France, the Loire River recorded three extreme floods on the years 1846, 1856 and 1866, while the Tech River and the Têt River recorded other important events on 1842 and 1843. This last one was more spread and also affected the Aude River that recorded other remarkable floods in 1858 and 1862. The Ardèche River recorded seven flood events between 1846 and 1861 (Lang et al, 2001) and some of these events also affected the Drac and Isère Rivers, with more than 20 flood events in Grenoble (Coeur, 2003). The Rhone River was also recorded extreme floods (2003). In Spain, more than 60 flood events were recorded in Catalonia on the period 1840-1870 (Llasat et al, 2005), but also the Duero River in the western part of the Iberian Peninsula, and the Turia, Jucar and Ebro Rivers in the Eastern part of the same experienced catastrophic floods. The contribution analyses the causes that have produced this anomalous flood period, with particular consideration to the fact that the usual meteorological situations associated to heavy rainfalls and floods in these regions and catchments are not the same, and that during this period land uses, urban planning and vulnerability experienced important changes. Potential changes in flood seasonality will be also considered. Early instrumental data collected on the framework of the European Project SPHERE and the Spanish National Project RAMSHES, between others and public information like 20th century reanalysis (Compo et al, 2011) will be also considered to reconstruct the meteorological patterns. Recent research on the impact of solar variability and teleconnections will be discussed, giving in mind the apparently contradictions between the dominant NAOI values during this period and the usual atmospheric circulation pattern associated to floods nowadays. Finally, a comparison with flood events recorded in the same

    The analysis of anthropometric data often allows investigation of patterns of genetic structure in historical populations. This paper focuses on interpopulational anthropometric variation in seven populations in Ireland using data collected in the 1890s. The seven populations were located within a 120-km range along the west coast of Ireland and include islands and mainland isolates. Two of the populations (the Aran Islands and Inishbofin) have a known history of English admixture in earlier centuries. Ten anthropometric measures (head length, breadth, and height; nose length and breadth; bizygomatic and bigonial breadth; stature; hand length; and forearm length) on 259 adult Irish males were analyzed following age adjustment. Discriminant and canonical variates analysis were used to determine the degree and pattern of among-group variation. Mahalanobis' distance measure, D2, was computed between each pair of populations and compared to distance measures based on geographic distance and English admixture (a binary measure indicating whether either of a pair of populations had historical indications of admixture). In addition, surname frequencies were used to construct distance measures based on random isonymy. Correlations were computed between distance measures, and their probabilities were derived using the Mantel matrix permutation method. English admixture has the greatest effect on anthropometric variation among these populations, followed by geographic distance. The correlation between anthropometric distance and geographic distance is not significant (r = -0.081, P = .590), but the correlation of admixture and anthropometric distance is significant (r = 0.829, P = .047). When the two admixed populations are removed from the analysis the correlation between geographic and anthropometric distance becomes significant (r = 0.718, P = .025). Isonymy distance shows a significant correlation with geographic distance (r = 0.425, P = .046) but not with admixture

    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

    Right whales (Eubalaena spp.) were the focus of worldwide whaling activities from the 16th to the 20th century. During the first part of the 19th century, the southern right whale (E. australis) was heavily exploited on whaling grounds around New Zealand (NZ) and east Australia (EA). Here we build upon previous estimates of the total catch of NZ and EA right whales by improving and combining estimates from four different fisheries. Two fisheries have previously been considered: shore-based whaling in bays and ship-based whaling offshore. These were both improved by comparison with primary sources and the American offshore whaling catch record was improved by using a sample of logbooks to produce a more accurate catch record in terms of location and species composition. Two fisheries had not been previously integrated into the NZ and EA catch series: ship-based whaling in bays and whaling in the 20th century. To investigate the previously unaddressed problem of offshore whalers operating in bays, we identified a subset of vessels likely to be operating in bays and read available extant logbooks. This allowed us to estimate the total likely catch from bay-whaling by offshore whalers from the number of vessels seasons and whales killed per season: it ranged from 2,989 to 4,652 whales. The revised total estimate of 53,000 to 58,000 southern right whales killed is a considerable increase on the previous estimate of 26,000, partly because it applies fishery-specific estimates of struck and loss rates. Over 80% of kills were taken between 1830 and 1849, indicating a brief and intensive fishery that resulted in the commercial extinction of southern right whales in NZ and EA in just two decades. This conforms to the global trend of increasingly intense and destructive southern right whale fisheries over time.

    On insanity, life crises and the longing for a "right life". A contribution to the discussion on the deviant behavior and mental disorders in the psychiatry of the 19th and 20th centuries using the example of patient stories. History of psychiatry, understood as social and cultural history, provides the framework for this micro-historical article. Using the example of three patients treated in Wuerttemberg or Baden psychiatric asylums between 1875 and 1912, the article focuses on the critical analysis of types of asylums, their practices of admissions, therapies and power relations between patients and staff. Ways of thinking and acting, subjective experiences and emotions are exemplified by patient records, personal testimonials and contemporary publications again by patients and staff. The article examines options of patients to influence the institutional daily asylum routine against the background of its complexity and dynamics. Borders, manipulations, malingering and querulous paranoia are at stake here. Furthermore, the article reflects various forms of social interaction with the power regulating therapeutic and disciplinary aspects against the backdrop of the "canons of rules" of the asylum as well as the contemporary political and legal framework.

    It has been theorized that declines in general intelligence (g) due to genetic selection stemming from the inverse association between completed fertility and IQ and the Flynn effect co-occur, with the effects of the latter being concentrated on less heritable non-g sources of intelligence variance. Evidence for this comes from the observation that 19th century populations were more intellectually productive, and also exhibited faster simple reaction times than modern ones, suggesting greater information-processing ability and therefore higher g. This co-occurrence model is tested via examination of historical changes in the utilization frequencies of words from the highly g-loaded WORDSUM test across 5.9 million texts spanning the period 1850-2005. Consistent with predictions, words with higher difficulties (δ parameters from Item Response Theory) and stronger negative correlations between pass rates and completed fertility declined in use over time whereas less difficult and less strongly selected words, increased in use over time, consistent with a Flynn effect stemming in part from the vocabulary enriching effects of increases in population literacy. These findings persisted when explicitly controlled for word age, changing literacy rates and temporal autocorrelation. These trends constitute compelling evidence for the co-occurrence model.

    Non-destructive and non-invasive micro-Raman fibre optic and micro-XRF analyses were performed to study a wallpaper from the beginning of the 19th century. The complementarity of these two non-destructive techniques is shown in this work. The analysed artwork is considered one of the most beautiful wallpapers ever manufactured according to the catalogues and books; it is known as Chasse de Compiègne, manufactured by Jacquemart, Paris, in 1812. During the analysis, an unexpected pigment was detected by both analytical techniques: lead-tin yellow type II. This pigment was used until ca. 1750, when other yellow pigments replaced it, thus it is very difficult to find it in paintings afterwards. Together with this pigment, red lead, Prussian blue, brochantite, yellow iron oxide, calcium carbonate, vermilion, carbon black of animal origin (bone black), lead white, and raw and burnt sienna were also determined by combining the analytical information provided by both techniques. A possible degradation of brochantite to antlerite is also discussed.

    This paper examines the State's assumption of medical care for patients with "permanent needs" in 19th century Spain. These patients were the incurably ill, the chronically ill and the elderly. This process is contextualized within the liberal reforms of the Spanish healthcare system in the reign of Isabel 11 (1833-1868). The goal of these reforms was the creation and consolidation of a national health system that would gradually replace the religious health charities. Healthcare reform became necessary due to the increase in migration that started in the 1830's and intensified in the 1850's. Traditional care networks formed by the family, local community and religious charities were no longer available to those who had left their village or town. In addition, many religious charities were bankrupted by the seizure of their properties in a programme of confiscation. Similar healthcare reform processes were taking place in the United Kingdom, France and Germany, among other European countries, and involved significant changes in the lives of patients, who became strictly controlled and medicalised. My aim was to identify changes in the patients' experience of illness through a case study of the living conditions of inmates at the Nuestra Señora del Carmen Hospital for Incurable Men, based in Madrid from 1852 to 1949. This was one of the institutions devoted to caring for patients with "permanent needs" and was under the direct control of the General State Administration.

    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.

    Edward Muybridge was an Anglo-American photographer, well known for his pioneering contributions in photography and his invention of the "zoopraxiscope," a forerunner of motion pictures. However, this 19th-century genius, with two original patents in photographic technology, made outstanding contributions in art and neurology alike, the latter being seldom acknowledged. A head injury that he sustained changed his behavior and artistic expression. The shift of his interests from animal motion photography to human locomotion and gait remains a pivotal milestone in our understanding of patterns in biomechanics and clinical neurology, while his own behavioral patterns, owing to an injury to the orbitofrontal cortex, remain a mystery even for cognitive neurologists. The behavioral changes he exhibited and the legal conundrum that followed, including a murder of which he was acquitted, all depict the complexities of his personality and impact of frontal lobe injuries. This article highlights the life journey of Muybridge, drawing parallels with Phineas Gage, whose penetrating head injury has been studied widely. The wide sojourn of Muybridge also illustrates the strong connections that he maintained with Stanford and Pennsylvania universities, which were later considered pinnacles of higher education on the two coasts of the United States.

    In this paper we studied the material composition of the ground layer of a neoclassical painting. We used Raman spectroscopy (RS) as a prime method. Thereafter scanning electron microscopy combined with energy dispersive spectroscopy (SEM-EDS) and X-ray powder diffraction (XRD) were employed as complementary techniques. The painting inspected was of the side altar in King St. Stephen's Church in Galanta (Slovakia), signed and dated by Jos. Chr. Mayer 1870. Analysis was carried out on both covered and uncovered ground layers. Four principal compounds (barite, lead white, calcite, dolomite) and two minor compounds (sphalerite, quartz) were identified. This ground composition is consistent with the 19th century painting technique used in Central Europe consisting of white pigments and white fillers. Transformation of lead white occurred under laser irradiation. Subdominant Raman peaks of the components were measured. The observed results elucidate useful partnership of RS and SEM-EDS measurements supported by X-ray powder diffraction as well as possibilities and limitations of non-destructive analysis of covered lower layers by RS.

    The history of modern pharmaceutical science and technology, from the second half of the 19th century to the end of World War II, is divided into nine sections for the purpose of discussion. 1. The European medical and pharmaceutical science and technology at the end of the 19th century is reviewed. Pharmacology, bacteriology and biochemistry were built in this period. 2. The Meiji Government accepted Western medicine and medical law and regulations in 1883. Consequently, the Japanese physician changed from Eastern (Kanpooi) to Western (Seiyooi). 3. Modern scientific and engineering education had been accepted in America, England, Germany, and France etc. Foreign scientists and engineers (Oyatoi-gai-kokujin) were educated by practice and theory. The Faculty of Engineering was established in the universities in Japan. This fact is one of the differences in the history of universities in Europe and America. 4. Pharmaceutical education in the Meiji period (1873-1911). Twenty-nine schools of pharmacy were built in this period. However, 20 schools of pharmacy had been closed. Pharmacy and pharmaceutical industry was not established in the Meiji era. 5. The profession of pharmacist in 1873-1944. The policy of medicine was changed by the Meiji Government in 1889, when Western physicians were allowed to prepare medicines for patients, and this practice continues today. Political and technological power of Japanese pharmacists was weak, so their role was not estimated. 6. Consequences of world War I, and the establishment of the pharmaceutical industry. The Sino-Japanese War (1894-95) and Russo-Japanese War (1904-05) were won fortunately. The first pharmaceutical company was established in 1885. At this times, many pharmaceutical manufacturing companies, which were converted from whole sale merchants, were built. Then started the manufacturing of commercial drugs. 7.

    Purpose To investigate the effects of eye diseases on several important artists who have been given little attention from a medical-historical viewpoint. The examples chosen demonstrate problems artists have had to face from different types of eye disease, including cataract, glaucoma, and retinal diseases. The ophthalmological care provided is described in terms of scientific knowledge at the time. Methods Investigation of primary and secondary source material. Discussion with art historians and ophthalmic historians. Examination of work by the artists. Results Artists can be markedly affected by ocular diseases that change their ability to see the world. The individuals described here worked during the 19th century and first half of the 20th century. Homer Martin suffered from cataracts, and his works reveal changes in details and color as he aged. Henri Harpignies, who had an extremely long career, undoubtedly had cataracts and may also have had macular degeneration. Angle-closure glaucoma blinded Jules Chéret. Auguste Ravier suffered from neovascular glaucoma in one eye and was able to work with his remaining eye, which developed a cataract. Louis Valtat suffered from what was in all likelihood open-angle glaucoma, but specific changes due to this disease are not apparent in his work. Roger Bissière developed glaucoma and did well following filtration surgery. George Du Maurier lost one eye from what was probably a retinal detachment and later suffered from a central retinal problem in the other eye. Conclusions Diseases of the eye may profoundly influence artists by altering their perception of the world. The specific effects may vary, depending on the disease, its severity, and the psychology of the artist. Cataracts typically affect an artist’s ability to depict color and detail. The effect of glaucoma generally depends on whether central vision is preserved. Disease that affects the center of the retina has a substantial effect on an artist’s ability

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

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

    The importance of understanding processes that govern the hydroclimate of the Mediterranean Basin is highlighted by the projected significant drying of the region in response to the increase in greenhouse gas concentrations. Here we study the long-term hydroclimatic variability of the central Levant region, situated in the eastern boundary of the Basin, as reveled by instrumental observations and the Holocene record of Dead Sea level variations. Observations of 19th and 20th century precipitation in the Dead Sea watershed region display a multidecadal, anti-phase relationship to North Atlantic (NAtl) sea surface temperature (SST) variability, such that when the NAtl is relatively cold, Jerusalem experiences higher than normal precipitation and vice versa. This association is underlined by a negative correlation to precipitation in the sub-Saharan Sahel and a positive correlation to precipitation in western North America, areas that are also affected by multidecadal NAtl SST variability. These observations are consistent with a broad range of Holocene hydroclimatic fluctuations from the epochal, to the millennial and centennial time scales, as displayed by the Dead Sea lake level, by lake levels in the Sahel, and by direct and indirect proxy indicators of NAtl SSTs. On the epochal time scale, the gradual cooling of NAtl SSTs throughout the Holocene in response to precession-driven reduction of summer insolation is associated with previously well-studied wet-to-dry transition in the Sahel and with a general increase in Dead Sea lake levels from low stands after the Younger Dryas to higher stands in the mid- to late-Holocene. On the millennial and centennial time scales there is also evidence for an anti-phase relationship between Holocene variations in the Dead Sea and Sahelian lake levels and with proxy indicators of NAtl SSTs. However the records are punctuated by abrupt lake-level drops, which appear to be in-phase and which occur during previously documented

  7. A model for the 19th century eruption of Eta Carinae: CSM interaction like a scaled-down Type IIn Supernova

    This paper proposes a simple model for the 19th century eruption of Eta Carinae that consists of two components: (1) a strong wind (dot{M}=0.33 M_{{odot }} yr-1; v∞ = 200 km s-1), blowing for 30 yr, followed by (2) a 1050 erg explosion (10 M⊙; 750-1000 km s-1) occurring in 1844. The ensuing collision between the fast ejecta and the dense circumstellar material (CSM) causes an increase in brightness observed at the end of 1844, followed by a sustained high-luminosity phase lasting for 10-15 yr that provides a close match to the observed historical light curve. The emergent luminosity is powered by converting kinetic energy to radiation through CSM interaction, analogous to the process occurring in more luminous Type IIn supernovae, except with ˜10 times lower explosion energy and at slower speeds (causing a longer duration and lower emergent luminosity). We demonstrate that such an explosive event not only provides a natural explanation for the light-curve evolution, but also accounts for a number of puzzling attributes of the highly scrutinized Homunculus, including: (1) rough equipartition of total radiated and kinetic energy in the event, (2) the double-shell structure of the Homunculus, with a thin massive outer shell (corresponding to the coasting cold dense shell) and a thicker inner layer (between the cold dense shell and the reverse shock), (3) the apparent single age and Hubble-like flow of the Homunculus resulting from the thin swept-up shell, (4) the complex mottled appearance of the polar lobes in Hubble Space Telescope images, arising naturally from Raleigh-Taylor or Vishniac instabilities at the contact discontinuity of the shock, (5) efficient and rapid dust formation, which has been observed in the post-shock zones of Type IIn supernovae, and (6) the fast (3000-5000 km s-1) material outside the Homunculus, arising from the acceleration of the forward shock upon exiting the dense CSM. In principle, the bipolar shape could be explained borrowing

    Sand landscapes occupy about half of the territory of the Netherlands. Apart from an insignificant amount of Tertiary deposits, these sands are of Pleistocene and Holocene age. They include Saalian push moraines, Weichselian cover sands and Holocene drift sands. To these geological landscapes, cultural variants should be added such as the essen, i.e. a landscape with plaggen soils, and reclaimed lands (e.g. former moors). Not included are the coastal sands, which we dealt with in an earlier EGU contribution (van den Ancker & Jungerius 2012). Nature and man created a wide variety of sceneries that inspired painters in the 19th and early 20th century (Jungerius et al. 2012). Painter communities on the sandy soils flourished in Oosterbeek/Wolfheze, Laren/Blaricum, Nijkerk, Nunspeet/Elspeet, Hattem and Heeze. Many of the landscape paintings are found in the database of Simonis en Buunk that can be freely consulted on line (http//www.simonis&buunk.com). For this presentation we selected specimens that show geodiversity-biodiversity relationships, some of which have changed since. Painters of push moraines were attracted by the rolling terrain, the dry valleys and occasionally the colourful podzol soil profiles. Popular themes in the cover sands were the undulating relief and heathlands with herds of sheep, sandy footpaths and country roads with erosion phenomena. The dynamics of erosion captivated the painters of Holocene drift sand scenery, as did the bare fields of cultivated lands. Their paintings show the rural areas that since the beginning of the 20th century lost their traditional charm in large-scale re-allotment schemes and artificial nature-building project, that changed geodiversity-biodiversity relationships. Changes in the sandy terrains that can be inferred from the paintings are on a landscape scale, the scale of the landform and vegetation type, and are illustrated by changes in colour, pattern, structure and texture. Examples are: · active drift sands

    In the early 19th century, Dr. Thibert discovered a process to overcome the difficulties of casting soft and moist organs. However, the analysis of a stomach made by Thibert reveals a modeling, changing the strict mechanical objectivity of the cast. This modeling inside the cast named "reparation" structures the illusionism of this cast. The scientific and artistic aspect of this study is to establish the typology of a secret modeling. This last one is the inheritance of the tricks of the mediocritas: between material and matter, so valuable for the goldsmiths of the 16th century.

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

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

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

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

Five kinds of pigments were found in the experimental data, including black (carbon), white (gypsum + quartz), blue (lapis lazuli) and green (Paris green + Barium sulphate). After synthesized in 1814, Paris green was reported for a large import as a light and bright green pigment to paint architectures in China from the late 19th century. The analyzed blue pigment demonstrated the similar Raman spectra to the Lâjvardina blue glazed ceramics, which indicated lapis lazuli was an artificial product. This confirmed the painting of Feixiange Cliff in the early Republic of China as the historical record, and also reveals that some pigments were imported from abroad.

Is medicine more (or only) science, or is it an art was the crucial point of discussion, which was held in European philosophy of the medicine for the first time in late 19th century. The important voice in it was given by Polish scientists such as Zygmunt Kramsztyk, Henryk Nusbaum, Władysław Biegański, Edmund Biernacki, Władyslaw Szumowski and Ludwik Zembrzuski. How they understood place and meaning of medicine in the realm of human activities, in which points they found the same grounds and in which they differed, should be seen as the main topic for this article.

    The portable pharmacy of Reichard, in his 1805 Guide for travelers in Europe is an example among others of a growing determination to answer the needs of the people to have access to drugs even in absence of health care professionals. One can observe the ultimate result by looking at portable pharmacies offered for sale by companies such as Menier and Pharmacie Centrale de France, but also by individual pharmacists. In spite of favorable changes of health care in all countries during the XXe century, portable pharmacy and kits are still widely proposed for sale, on Internet for example, for frequent diseases, including for pets!

Thereby the recent concept of ,male health-idiots' will be challenged in historical perspective.

    Historical weather and climate data are essential for the establishment of long-term climate patterns and future projections. For South Africa, where there is a paucity of such long-term climate data, it undermines the ability to establish climate changes and variability over longer periods of the past few centuries. Consequently, analyses of climate change in the region have relied on relatively poor resolution proxy records. Yet, the recently discovered instrumental meteorological records of the Royal Astronomical Observatory in Cape Town provides South Africa's (and possibly the southern hemisphere's) longest continuous time series of daily recorded weather measurements, including temperature, rainfall, barometric pressure and wind (1835 to present). Wind specifically is a reliable indicator of dynamic atmospheric circulation and lends supporting data for understanding the Mediterranean climate of the region. This project has manually digitized, pre-processed and validated wind data from the earliest records by comparing these data with the only other known wind data for that time in the region - namely ship log data. Ship log data, recovered and digitized by the CLIWOC project, are used for statistical correlation (using wavelet query analysis) and trend analysis for the period 1843 to 1855. Both data sources indicate the same general wind climatological trends. The similarly decreasing trend in average wind velocity over the time period investigated, suggests that the data have been adequately captured and that ship log data are representative of adjoining land-based synoptic conditions. It is hoped that short term cyclic/extreme events can be extracted using a wavelet query analysis by correlating the data at various time steps. Differences in the timing of recordings and spatial scales between data sets present challenges for such a comparison. This work is part of a larger digitization project which is analysing Cape instrumental and documentary weather

    2004-01-01

    This paper argues that our modern concept of biological heredity was first clearly introduced in a theoretical and practical setting by the generation of French physicians that were active between 1810 and 1830. It describes how from a traditional focus on hereditary transmission of disease, influential French medical men like Esquirol, Fodéré, Piorry, Lévy, moved towards considering heredity a central concept for the conception of the human bodily frame, and its set of physical and moral dispositions. The notion of heredity as a natural force, with a wide ranging capabilities of transmitting differentially both fundamental and accidental characters was generalized by that generation of physicians with the help of contemporary naturalists and physiologists. By 1830 the term hérédité was widespread, and it shared the explanatory and semantic qualities of traditional medical concepts like constitution and temperament. An analysis is given of the main developments that led to the conception of biological (including human) bodies as consisting of a layered, hierarchical organization of characters, differentially affected by the law of conservation (Heredity) and change (Inneity, Variation). The mid-century work of the French physician Prosper Lucas, Traité Philosophique et Physiologique de L' Hérédité Naturelle, is shown to be the culmination of the efforts of several generations of French physicians towards having a feasible, complexly structured notion of how heredity works.

    The development of nursing began in Poland much later than it did elsewhere, for instance in the United Kingdom, the United States, or Germany, and it came up against difficult conditions. After a brief twenty-year period of development between 1918 and 1939, it almost stalled during the war (1939-45), only to be followed by nearly twenty years of chaos. Nursing started to come out of this difficult period at the beginning of the 1960s. The turn of the 21st century saw the emergence of extensive professional development and training opportunities for nurses. This change was brought about as much by political, social and economic issues, health care requirements, and the advancement of science, medicine, the birth of humanitarism, the growth of the feminist movement, the European Agreement on the Instruction and Education of Nurses, the WHO European Strategy for Nursing and Midwifery Education, the Bologna declaration, as well as the activities undertaken by the European Union, the International Council of Nurses, the American and Polish Red Cross, the Rockefeller Foundation, the Polish Association of Nurses, and the professional self-governing body. The transformation of nursing into an independent profession was further boosted by physicians deeply involved in the issue and female pioneers of nursing.

    After the early meteorological observations of the 1770s to the 1790s in continental Portugal (including a 5 year daily series by J. Velho), there were hardly any until 1815. In December 1815, a meteorological station was set up in Lisbon by Marino Miguel Franzini (1779-1861), an engineer who was also actively involved in Politics (liberal party). Following the tradition of the 18th century enlightenment movement, he took a keen interest in Nature and Sciences, particularly in the "influence" of weather and climate on health and agriculture. Franzini started his observations by request of a physician who sought to understand the reasons why the maximum mortality occurred on the summer months, unlike in northern countries of Europe where maximum mortality occurred in winter (as it happens nowadays in Portugal). The deterministic background of the two scientists is clear. Franzini was a member of the Lisbon Academy of Sciences (founded in 1799) and had contact with foreign Academies and foreign scientists. His instruments were carefully constructed and described, including graduation scales, and stations' location was indicated. Data from two years observations (several meteorological variables) was published in the Academy of Sciences Memoirs. From 1818 until 1826 and from 1835 until 1856 data was divulged in journals and newspapers, such as the "Journal of Medical Sciences", together with data on necrology in some of Lisbon parishes (illustrating the interest of physicians on weather); meteorological data and information about agriculture was also published in the "Lisbon Gazette". Unfortunately, there are hardly any daily data, as Franzini grouped his records according to weather types, as will be explained. Franzini's series will be presented in our talk. The gap between 1826 and 1835 was due to the political activities in which Franzini was involved: the civil war (liberals against absolutist) disruptedscientific research in Portugal.

    Artur Wołyński (1844-1893) was, undoubtedly, one of the most interesting personages of Polish émigrés after January Uprising. He belonged to these circles of Polish émigrés, who were able to reconcile their patriotic aspirations with realities and interest of the countries that entertained them. As far as Wołyński is concerned, it found its expression in the efforts that were made in order to assimilate two nations--Polish and Italian people--appealing to the common history and familiar cultural traditions. An important element of integrating all the above-discussed actions was his scientific activity. The mentioned activity included, first of all, his studies on Nicolaus Copernicus and Galileo Galilei. In the article were analyzed more comprehensive scientific descriptions dedicated to Copernicus and Galileo prepared by Wołyński, and their significance and opinions on them of the learned, whose works treated on Copernicus and Galileo as well. Secondly, in the field of scientific activity of Wołyńiski, one can also observe his researches and the process of elaborating sources for Polish and Italian his tory, particularly concerning the 17th century. However, most of his attention Wołyński paid to collecting and working out the materials concerning January Uprising. Speaking a modern language, one can say that Wołyński in a way polled the insurgents of January Uprising sending to them an appropriate list of questions, additionally allowing for their biographies. In the paper was also included a detailed description of this broad initiative together with its results. Up till now, not much attention has been paid to this significant scientific activity and its contexts. So, the present article is to remind of meritorious personage of Wołyński, and particularly of his output within the realm of history of science, history of Polish and Italian relationships, and of the role he played in bequeathing memory of January Uprising.

  7. Do conditions in early life affect old-age mortality directly and indirectly? Evidence from 19th-century rural Sweden.

    Previous research has shown that the disease load experienced during the birth year, measured as the infant mortality rate, had a significant influence on old-age mortality in nineteenth-century rural Sweden. We know that children born in years with very high rates of infant mortality, due to outbreaks of smallpox or whooping cough, and who still survived to adulthood and married, faced a life length several years shorter than others. We do not know, however, whether this is a direct effect, caused by permanent physical damage leading to fatal outcomes later in life, or an indirect effect, via its influence on accumulation of wealth and obtained socio-economic status. The Scanian Demographic Database, with information on five rural parishes in southern Sweden between 1813 and 1894, contains the data needed to distinguish between the two mechanisms. First, the effects of conditions in childhood on obtained socio-economic status as an adult are analyzed, then the effects of both early-life conditions and socio-economic status at various stages of life on old-age mortality. By including random effects, we take into account possible dependencies in the data due to kinship and marriage. We find that a high disease load during the first year of life had a strong negative impact on a person's ability to acquire wealth, never before shown for a historical setting. This means that it is indeed possible that the effects of disease load in the first year of life indirectly affect mortality in old age through obtained socio-economic status. We find, however, no effects of obtained socio-economic status on old-age mortality. While the result is interesting per se, constituting a debatable issue, it means that the argument that early-life conditions indirectly affect old-age mortality is not supported. Instead, we find support for the conclusion that the effect of the disease load in early-life is direct or, in other words, that physiological damage from severe infections at the

Last but not least, our data archeology exercise will provide additional evidence to the intriguing relation that was first noted by Miller and Douglas (2007) between sea level on the eastern boundary of the North Atlantic and the strength of the gyre-scale circulation, as represented by air pressure in the centre of the gyre, on multi-decadal and century-timescales.

    Through the combined use of infrared (IR) absorption spectroscopy and attenuated total reflectance (ATR) sampling, the composition of inks used to print the many different types of one-cent Benjamin Franklin stamps of the 19th century has been established. This information permits a historical evaluation of the formulations used at various times, and also facilitates the differentiation of the various stamps from each other. In two instances, the ink composition permits the unambiguous identification of stamps whose appearance is identical, and which (until now) have only been differentiated through estimates of the degree of hardness or softness of the stamp paper, or through the presence or absence of a watermark in the paper. In these instances, the use of ATR Fourier transform infrared spectroscopy (FT-IR) spectroscopy effectively renders irrelevant two 100-year-old practices of stamp identification. Furthermore, since the use of ATR sampling makes it possible to obtain the spectrum of a stamp still attached to its cover, it is no longer necessary to identify these blue Franklin stamps using their cancellation dates.

    Beginning in the mid-19th century, several generations of woman suffrage supporters lectured, wrote, marched, lobbied, and practiced civil disobedience to achieve what many people considered a radical change in the U.S. Constitution. Militant suffragists used tactics such as parades, silent vigils, and hunger strikes. In 1870 the 15th amendment to…

  11. A three-variable chaotic system for the epidemic of bubonic plague in Bombay by the end of the 19th century and its coupling to the epizootics of the two main species of rats

    A plague epidemic broke out in Bombay by the end of the 19th century. A committee was first appointed by the Bombay City [1] in order to stop the epidemic before the rain season started. Unfortunately, the disease could not be stopped and the epidemic became endemic. After several years, another Advisory Committee [2] was appointed that tried to investigate the causes of plague in all possible directions. An impressing quantity of information was gathered during the period 1907-1911 and published. In particular, it was noticed that the epidemic was systematically preceded by epizootics of rats. For this reason, the populations of the main species of rodents were systematically monitored. This data set is revisited here by using a multivariate version of the global modeling technique [3]. The aim of this technique is to obtain a set of Ordinary Differential Equations directly from time series. Three observational time series are considered: the number of person died of bubonic plague per half month (1), and the number of captured infected black rats Mus rattus (2) and brown rats Mus decumanus (3). Several models are obtained, all based on the same algebraic basic structure. These models are, either directly chaotic, or close to chaos (chaos could easily be obtained by tuning one model parameter). The algebraic structure of the simplest model obtained is analyzed in more details. Surprisingly, it is found that the interpretation of the coupling between the three variables can be done term by term. This interpretation is in quite good coherence with the conclusions of the Advisory Committee published one hundred years ago. This structure also shows that the human action to slow down the disease during this period was obviously effective, although insufficient to stop the epidemic drastically. This result suggests that the global modeling technique can be a powerful tool to detect causal couplings in epidemiology, and, more generally, among observational variables from

    than observations from the existing network of meteorological offices. Some researchers have even suggested that the entire period before radar observation, beginning in the 1980s, should be classified as pre-instrumental. However, it is undoubted that documents kept in the archives of insurance companies provide valuable proxy information on hail storm occurrence for, at least, the pre-1950-period (well back into the 19th century). This paper discusses key problems in dealing with these proxy data (reliability, interpretation and density of records), as well as methodologies that may lead to extend existing time series on hail storm occurrence in Switzerland. As a consequence, this paper suggests that, for some meteorological phenomena, the field of reconstruction from documentary archival sources must be extended well up into the 20th century, which cannot simply and statically be categorized as "instrumental period”.

    The floods were classified according to a severity scale derived from the contents of the historical sources. It enables an evaluation of these events in spite of the lack of instrumental data for the major part of period. It shows that the chronology and the severity of the floods in this part of England were contradictory from one century to another one and that their origins, as their seasonality, underwent not insignificant changes. The paper then shows that local societies (urban and rural) did not passively accept these extreme climate events. It shows that the flood questioned directly challenged the socioeconomic balance of the populations and that they tried to face it in a pragmatic and sustainable way.

    Sexuality has been defined a central feature of personal identity since the epoch of enlightenment and has gradually become a decisive issue also in societal and political terms. A major transfer from religion and religious institutions to medicine and medical experts and later on to neuropsychiatrists has to be underlined in the primary position to assess "normal" and "deviant" manifestations of sexuality. Richard Freiherr von Krafft-Ebing and Sigmund Freund play an eminent role in this "discourse on sexuality" (M. Foucault) during the nineteenth and beginning twentieth century on the way to modern sexology. Within this overarching context Krafft-Ebing's and Freud's theoretical conceptualizations of sexuality and perversion will be sketched and basic clinical and societal implications there out will be discussed.

    Sarmiento believed that Copernican astronomy was one of the critical scientific disciplines to the formation of a "modern" citizen. In this work, we shall study astronomical science from two points of view: from the scientific knowledge and the educational presentation of such knowledge. Our study will address in Argentina in 19th century, starting from the initiative of Bernardino Rivadavia in 1821, who founded an astronomic observatory at Buenos Aires, until the first activities of the observatories at Córdoba and La Plata. On both lines, scientific and educative, we shall analyze the influence of positivist ideas. We shall highlight epistemological differences between both observatories, Córdoba's based on French positivism and La Plata's based on German positivism. We shall also show the different attitude of both observatories towards education. We shall see the way in which positivist ideas had great relevance in the training of elementary school teachers. We shall also establish the relevant influence of the socio-historical context over the astronomical development, and show that astronomy was a fundamental social factor at Argentina history. Domingo F. Sarmiento consideraba que la astronomía copernicana era una de las disciplinas científicas fundamentales para la conformación de un ciudadano "moderno".

    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.

    In the course of the nineteenth century, Saarbruck developed from a small provincial town to the centre of a large region rapidly becoming industrialised. The traditional civil hospital underwent a fundamental change: from a residence for the old, the poor, and the neglected it became a modern hospital intended to restore health and fitness to the growing number of young working people in the region. To help the hospital meet its new aims, Reverend Fliedner of the Protestant Deaconesses' Institution in Kaiserswerth on the Rhine sent two young deaconesses to the hospital in Saarbruck. Expecting to work as a nurse and housekeeper, the two inexperienced and under-trained women were virtually overwhelmed by what they encountered. Their work required very hard physical work, with very little or no assistance. This study is based on the series of letters of appeal the deaconesses sent to Kaiserswerth, which depict in great detail the conditions of the hospital during the transition period. Different groups of inmates can be distinguished: old and poor patients representing hospital's traditional function; journeymen and domestic servants who are far from home and no longer under their employers' care, and miners with rather severe injuries. Miners constitute the prototype of the new industrial working class, as the mining industry was by far the most important sector of the developing economy. All groups benefited from the deaconesses' zeal to establish new standards of cleanliness and nutrition, not to mention the beginning of professional medical care. On the other hand, they have to submit to middle class expectations and behaviour. For instance, heman miners were expected to follow orders from female nurses, and domestic servants afflicted with scabies or venereal disease were expected to adopt new standards of moral and orderly demeanour. Resistance was mainly passive, consisting of paying lip service to the rules, taking small liberties, and reverting to the old

    The enamel of teeth from 57 children, who died in the mid to late 1800s, were analysed to investigate strontium (Sr) concentrations in historic teeth. Teeth were analysed using proton induced X-ray emission at the Australian Nuclear Science and Technology Organisation (ANSTO). Where available, multiple teeth were analysed for each individual including permanent (molars and premolars) and deciduous teeth (molars). Preliminary results show that Sr does not appear to be affected by the postmortem environment. Sr levels in permanent molars strongly correlate with levels in the premolars but not with the deciduous molars. Concerns are raised over the large variation seen in Sr levels and the effect it would have on the interpretation of Sr levels in studies with small sample sizes.

    Carl Wernicke (1848-1905) is traditionally considered the first to have described the features of, and the brain pathology underlying, impaired auditory comprehension and related symptoms. Although Wernicke (1874) clearly and repeatedly indicates his indebtedness to Theodor von Meynert (1833-1892), this is usually understood as an acknowledgment that Meynert taught Wernicke neuroanatomy (Eggert, 1977); Wernicke's own words in part support this interpretation. A more sophisticated historical analysis notes that, prior to Wernicke, both Johann Schmidt in 1871 and Charlton Bastian in 1869 had described the concept of receptive aphasia, but neither had supported their analyses with autopsy evidence as did Wernicke, thus not dislodging Wernicke's claim of priority. However, a virtually unknown work by Theodor von Meynert, published in 1866, has recently been rediscovered by us ["Ein Fall von Sprachstörung, anatomisch begründet." Medizinische Jahrbücher. XII Band der Zeitschrift der K. K. Gesellleschaft der Arzte in Wien, 22. Jahr. Pp. 152-189]. In this paper Meynert analyzes the anatomical basis for localizing the comprehension of language in the superior temporal gyrus, he argues that lesions in this area should (by analogy to Broca's earlier observations on language expression) cause impairments in language comprehension, and he presents a case of receptive aphasia with autopsy evidence of destruction of the superior temporal gyrus in the left hemisphere. The patient's aphasia was classic; impaired auditory comprehension, and fluent speech with paraphasias. It is clear that Meynert should be given historical credit for his work.

    The first cholera outbreak on Bourbon Island (now Reunion Island) was recorded in January 1820. The disease was imported from Mauritius Island aboard the steamer Pivert. The epidemic began on Mauritius in November 1819 after the English frigate, La Topaze, called from Calcutta, India. Dr. François Vinson demonstrated the transmissibility of cholera during this epidemic. Drastic sanitary measures spared Reunion from the two epidemics on Mauritius Island, in 1854 and 1856. The second outbreak of cholera on Reunion Island was recorded on March 6, 1859. The disease was introduced from East Africa by the steamer Mascareignes, which carried indentured servants. The captain (d'Agnel) et the supercargo (Menon) of the steamer claimed to the doctor who boarded the ship before landing that no passengers or crew had had cholera, in flagrant contradiction to the autopsy report issued by Navy surgeon Alfred Vaillant, who had concluded that cholera was present when the vessel left the African coast. This report was withheld from the boarding physician. Cholera spread quickly on the island and affected the poorest people, especially freed slaves, most severely. Dr. Petit, the chief Navy Physician and Director of the Health Department, obtained a confession by Menon about the fraudulent statements. On January 24, 1860, a trial for public health endangerment began on Reunion Island; it ended on February 1 with a not-guilty verdict, based largely on the testimony of several island doctors that cholera was not contagious.

    Etienne Leopold Trouvelot, born in France in 1827, came to the United State with his family in 1855, settling in Massachusetts. He supported his family as an artist, but became interested in astronomy after observing and sketching auroras in the 1870s. When astronomers at Harvard saw the quality and detail in these drawings, they invited him to join the staff and use their telescopes for observation and making drawings of celestial objects. In 1875 the U. S. Naval Observatory invited him to Washington to use the 26 inch refractor, at that time the world's largest refractor. Through the years he made more than 7000 drawings which were highly regarded by astronomers who saw them, especially for the fine detail of the drawings. Trouvelet wanted to publish a portfolio of some of the best drawings and approached Charles Scribner's Sons, publishers in New York. The 15 drawings he chose were produced as chromolithographs, and the set was published in 1881 selling at \\$125. Very few complete sets remain in institutions today, and one set sold at auction within the last few years for many times the original price. However, Trouvelot will always be remembered not for his astronomical artistry but as the person who introduced the gypsy moth into the United States. In his attempt to bring better silk producing caterpillars into the country, some egg masses escaped and the rest is history.

    Primary energy demand in China and India has increased fivefold since 1980. To avoid power shortages and blackouts, the hydropower infrastructure in the Hindu Kush-Himalaya region is seeing massive development, a strategy supported by the policy of the World Bank and in harmony with the framework of the Kyoto Protocol. The targeted investments in clean energy from water resources, however, may trigger far-reaching impacts to downstream communities given that hydropower projects are planned and constructed in close vicinity to glaciated areas. We hypothesize that the location of these new schemes may be subject to higher exposure to a broad portfolio of natural hazards that proliferate in the steep, dissected, and tectonically active topography of the Himalayas. Here we focus on the hazard from glacial lake outburst floods (GLOF), and offer an unprecedented regional analysis for the Hindu Kush-Himalaya orogen. We compiled a database of nearly 4,000 proglacial lakes that we mapped from satellite imagery; and focus on those as potential GLOF sources that are situated above several dozen planned and existing hydropower plants. We implemented a scenario-based flood-wave propagation model of hypothetic GLOFs, and compared thus simulated peak discharges with those of the local design floods at the power plants. Multiple model runs confirm earlier notions that GLOF discharge may exceed meteorological, i.e. monsoon-fed, flood peaks by at least an order of magnitude throughout the Hindu Kush-Himalaya. We further show that the current trend in hydropower development near glaciated areas may lead to a >15% increase of projects that may be impacted by future GLOFs. At the same time, the majority of the projects are to be sited where outburst flood modelling produces its maximum uncertainty, highlighting the problem of locating minimum risk sites for hydropower. Exposure to GLOFs is not uniformly distributed in the Himalayas, and is particularly high in rivers draining the Mt

    We present the results of our long-term UBVJHKLM photometry and spectroscopic monitoring of the symbiotic nova V1016 Cyg. After its outburst in 1964, the star showed fading in the U, B, V bands at a rate of about 0.03 mag per year. The behavior of the B-V and U-B color indices reflects variations of the emission lines, fading of the erupted component, weakening and reddening of the cool giant. Also, monotonic color and brightness variations in the infrared (IR) were observed at a scale of several thousand days. After 2004, the yearly mean IR brightness showed a decline and IR colors, reddening, due to the increase of the optical depth of the dust. The parameters of the cool star and of the dust envelope were estimated. The pulsation period of the Mira-type variable was refined, P=465±5 days. The Mira's photospheric temperature varied from 2100 to 2700 K in the pulsation cycle. The mass of the dust shell has grown twice during the recent decade, at a dust penetration rate of Δ Mdust ∼10-7 M⊙/yr. Our spectroscopic monitoring of V1016 Cyg over 1995--2013 showed variations in the emission line strengths. The absolute fluxes of most lines decreased after 2000, whereas the relative intensities of [O III], [Ar III], [Fe VII], [Ca VII] lines with respect to Hβ are increasing after the possible minimum that could happen in the 1990s. An essential flux decline (approximately ten-fold between 1995 and 2013) in the Raman scattered O VI line at λ 6825 shows the change of conditions in its formation zone, due to absorption of O VI 1032 Å quanta in the new dust shell of the cool component.

  16. Lithographic image simulation for the 21st century with 19th-century tools

    Gordon, Ronald L.; Rosenbluth, Alan E.

    2004-01-01

    Simulation of lithographic processes in semiconductor manufacturing has gone from a crude learning tool 20 years ago to a critical part of yield enhancement strategy today. Although many disparate models, championed by equally disparate communities, exist to describe various photoresist development phenomena, these communities would all agree that the one piece of the simulation picture that can, and must, be computed accurately is the image intensity in the photoresist. The imaging of a photomask onto a thin-film stack is one of the only phenomena in the lithographic process that is described fully by well-known, definitive physical laws. Although many approximations are made in the derivation of the Fourier transform relations between the mask object, the pupil, and the image, these and their impacts are well-understood and need little further investigation. The imaging process in optical lithography is modeled as a partially-coherent, Kohler illumination system. As Hopkins has shown, we can separate the computation into 2 pieces: one that takes information about the illumination source, the projection lens pupil, the resist stack, and the mask size or pitch, and the other that only needs the details of the mask structure. As the latter piece of the calculation can be expressed as a fast Fourier transform, it is the first piece that dominates. This piece involves computation of a potentially large number of numbers called Transmission Cross-Coefficients (TCCs), which are correlations of the pupil function weighted with the illumination intensity distribution. The advantage of performing the image calculations this way is that the computation of these TCCs represents an up-front cost, not to be repeated if one is only interested in changing the mask features, which is the case in Model-Based Optical Proximity Correction (MBOPC). The down side, however, is that the number of these expensive double integrals that must be performed increases as the square of the mask unit cell area; this number can cause even the fastest computers to balk if one needs to study medium- or long-range effects. One can reduce this computational burden by approximating with a smaller area, but accuracy is usually a concern, especially when building a model that will purportedly represent a manufacturing process. This work will review the current methodologies used to simulate the intensity distribution in air above the resist and address the above problems. More to the point, a methodology has been developed to eliminate the expensive numerical integrations in the TCC calculations, as the resulting integrals in many cases of interest can be either evaluated analytically, or replaced by analytical functions accurate to within machine precision. With the burden of computing these numbers lightened, more accurate representations of the image field can be realized, and better overall models are then possible.

    We conducted a GPR (Ground Penetrating Radar) survey as part of a forensic investigation of the Second Site Cemetery (Rice Cemetery, Hartt Cemetery) in Mecklenburg County, North Carolina. The oldest marked grave at Second Site is 1797, although it is likely that unmarked graves date back to 1780. The most recent marked grave is dated 1848, but forensic evidence suggest that Second Site was in active use until at least the 1880s. The Second Site cemetery contains a "members" section and a "servants" section. The servants section contains graves of slaves, former slaves, and possibly other individuals. Our objectives were to determine the locations of unmarked graves in the servants cemetery, and to define the GPR characteristics that might help distinguish between burials in simple (or no) enclosures and those involving ornamented caskets with hardware. We selected a 15 m by 15 m section of the servants cemetery (Section A) and a second 5 m by 5 m section (Section Z) to conduct GPR surveys, and excavated one grave in each section. Our GPR surveys were done with a GSSI SIR 3000 and a 400 MHz antenna in distance mode. The Section A GPR survey comprised parallel north-south profiles at 0.2 m intervals, and a set of cross lines at 0.5 m spacing. The Section Z profiles were north-south but at a spacing of 0.4 m. Soils in the cemetery are CeB2: Cecil sandy clay loam, clay, clay loam, and sandy loam derived from saprolitized metagranite. We established that a relative permittivity of 3 was suitable for this site at average depths of about 1.5 m, the nominal depth of burial. GPR profiles in both sections revealed some common geophysical characteristics. Most graves are longitudinally oriented east-west. Our north-south profiles therefore define grave lengths. Graves in non-migrated GPR sections are parabolic reflections with lower frequency responses than background. The size, shape, and spectral qualities of these reflections distinguish them from other sources (debris, stones, roots). We found a horizontal reflective horizon about 0.5 m thick at depths of 1.0-1.5 m that coincides with a hard clay soil layer exposed in excavations. Most grave shafts terminate within this horizon. This clay layer may be a normal part of the soil profile and not an accumulation zone at the bottom of grave shafts, but this is still to be verified by soil profiles. The grave in Section A contained iron nails, metal thumb screws, in situ swing bail handles, some still attached to carbonized casket wood, ceramic buttons, and very poorly preserved human remains. An worn eye coin from this grave was dated 1876, the maximum date of interment. The excavated, undated grave in Section Z, which unexpectedly contained a double burial, produced sparse small, iron wood nails and minimal human remains. The Section A grave showed a well-defined GPR reflection with which we can correlate other graves in the servants cemetery. In contrast, the Section Z grave produced a much weaker reflection probably because of the general absence of hardware. We believe it is possible to begin to map burial practices on the basis of the GPR characteristics of each grave.

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

    Silas Weir Mitchell (1829-1914), one of the fathers of American neurology, is well known for many contributions to neurology. However, his efforts in epilepsy are overshadowed by his other accomplishments. Mitchell introduced a new bromide preparation, lithium bromide, as a viable therapy. His most widely accepted contribution to the field was the introduction of inhaled amyl nitrite for early termination of seizures accompanied by an appropriate aura. Despite the prevalent views on lifestyle modification as a treatment for epilepsy during this time period, as well as Mitchell's own development of the "rest cure" for certain disease states, he was not a proponent of these types of interventions for epilepsy, nor did he support interventions focused on other organ systems, such as abdominal or gynecologic surgery. Mitchell had distinct opinions on the treatment of epilepsy, and helped to advance its therapeutics during his career.

    Aims: The latitudinal evolution of sunspot emergence over the course of the solar cycle, the so-called butterfly diagram, is a fundamental property of the solar dynamo. Here we present a study of the butterfly diagram of sunspot group occurrence for cycles 7-10 and 11-23 using data from a recently digitized sunspot drawings by Samuel Heinrich Schwabe in 1825-1867, and from RGO/USAF/NOAA(SOON) compilation of sunspot groups in 1874-2015. Methods: We developed a new, robust method of hemispheric wing separation based on an analysis of long gaps in sunspot group occurrence in different latitude bands. The method makes it possible to ascribe each sunspot group to a certain wing (solar cycle and hemisphere), and separate the old and new cycle during their overlap. This allows for an improved study of solar cycles compared to the common way of separating the cycles. Results: We separated each hemispheric wing of the butterfly diagram and analysed them with respect to the number of groups appearing in each wing, their lengths, hemispheric differences, and overlaps. Conclusions: The overlaps of successive wings were found to be systematically longer in the northern hemisphere for cycles 7-10, but in the southern hemisphere for cycles 16-22. The occurrence of sunspot groups depicts a systematic long-term variation between the two hemispheres. During Schwabe time, the hemispheric asymmetry was north-dominated during cycle 9 and south-dominated during cycle 10.

    Between 1878 and 1882, key members of the American scientific community played an important role in Thomas A. Edison's work on electric lighting. Impressed by his abilities, these scientists came to regard Edison as a peer and led him to see himself as a scientific man. But Edison's high standing among scientists and the American public and his professed self-image as a scientist provoked America's noted experimental physicist, Henry A. Rowland, to make a "Plea for pure science" before the American Association for the Advancement of Science in 1883.

    Research on solar-terrestrial relationships today relies primarily on in situ space data. These data, however, cover only a short period of about 30 years. Many solar and related phenomena vary on much longer time scales. For the study of these, parameters such as sunspots, magnetic activity, auroral occurrence, or other proxy data are required. Historical records of aurora are particularly useful in this connection.

    A historiographic paper in which the authors--psychiatrists--deal, based on research in archives, with the period preceding by approximately 100 years the opening of the psychiatric sanatorium in Opava. The beginnings of institutional care of the mentally sick in the Silesion region were in 1841 and were associated with the construction of an "asylum" on the grounds of the newly built hospital in Opava, a small house for 20-24 patients kept under inhuman conditions. An advance was the provisional arrangement involving the lease of a castle in Albrechtice for 36 and finally 90 patients in 1873. The regulations of the institute and rules of behaviour of the keepers were already on an advanced level of psychiatric in-patients care. The concept of the Opava sanatorium was according to documents in the archives elaborated by the 51-year-old Dr. Franz Köstl, one of the founders of Prague psychiatric institutions. His project has been preserved. The Opava sanatorium was opened and work started on March 29, 1889.

    The populations of light-demanding trees that dominate the canopy of central African forests are now aging. Here, we show that the lack of regeneration of these populations began ca. 165 ya (around 1850) after major anthropogenic disturbances ceased. Since 1885, less itinerancy and disturbance in the forest has occurred because the colonial administrations concentrated people and villages along the primary communication axes. Local populations formerly gardened the forest by creating scattered openings, which were sufficiently large for the establishment of light-demanding trees. Currently, common logging operations do not create suitable openings for the regeneration of these species, whereas deforestation degrades landscapes. Using an interdisciplinary approach, which included paleoecological, archaeological, historical, and dendrological data, we highlight the long-term history of human activities across central African forests and assess the contribution of these activities to present-day forest structure and composition. The conclusions of this sobering analysis present challenges to current silvicultural practices and to those of the future. DOI: http://dx.doi.org/10.7554/eLife.20343.001 PMID:28093097

    2012-03-07

    Two hundred years ago, the naturalist William John Burchell departed from Cape Town on extensive travels in South Africa 'solely for the purpose of acquiring knowledge'. An intelligent observer who was exceptionally skilled at recording his observations in words and pictures, he is remembered for numerous contributions to the country as scientist, artist and ethnographer. The medical perspective on his travels has yet to receive attention. He identified and recorded illnesses of the indigenous peoples with whom he came into contact. He also described the medical care he administered to his companions and to himself; in doing so, he revealed a profound care for his 'fellow creatures'. His vivid and sometimes poignant descriptions remind us of some of the health risks endured by early travellers in the country. One of the most riveting is his successful care of an assistant whose left hand was severely mutilated when a firearm exploded in his hands. Burchell was probably the first person to include the materia medica of the Khoi in an essentially European approach to the non-surgical management of such a serious condition.

    The documentation of Cultural Heritage asset is the basis for all the interventions and policies on Cultural heritage conservation and management. The documentation is mainly based on historic knowledge and metric survey. As far as historic knowledge is concerned many information are still recorded and preserved inside written documents that are usually not easy to reach and correctly understandable by all the experts that have specific responsibilities on Cultural Heritage. The digitalization of documents (hardly faced in the last years) is not sufficient to guarantee the effective access to the historical information useful inside a documentation process. The documentation always needs an historical interpretation based on a critical reading produced by linking heterogeneous materials. Iconography also is an important source when it is correctly interpreted and linked to other sources. IT development and digital technology diffusion allowed offering new way to record, organize and share historical information: GIS and 3D modeling can be used as standard approaches to transfer the historical knowledge in a proper way to specialists involved in Cultural Heritage conservation and management. They have been generally used as tool to represent information for different targets, the ones mostly for specialized users, the others for edutainment. GIS are largely diffused yet in the Cultural Heritage management, and 3D modeling is wide spread used in museums communication. Nevertheless, both of them have more potential. They could be integrated in order to manage different data set related with the same matter. They could be used to make new research by surveying and improving interpretation in a way ready to transmit the outcomes. To produce a new generation of affordable digital historical products is necessary that the GIS and 3D modeling design and realization would be developed in a multidisciplinary approach that must be explained and demonstrated to the people that in the future will offer to the community this expertise. The paper describes a teaching and research training experience started two years ago at the Politecnico di Torino in the master course on Architecture (Conservation).

    Jean-Martin Charcot (1825-93) was a well-known French neurologist. Although he is widely recognized for his discovery of several neurological disorders and his research into aphasia, Charcot's ideas about how the brain processes music are less well known. Charcot discussed the music abilities of several patients in the context of his 'Friday Lessons' on aphasia, which took place at the Salpêtrière Hospital in Paris in 1883-84. In his most comprehensive discussion about music, Charcot described a professional trombone player who developed difficulty copying music notation and playing his instrument, thereby identifying a new isolated syndrome of music agraphia without aphasia. Because the description of this case was published only in Italian by one of his students, Domenico Miliotti, there has been considerable confusion and under-acknowledgement of Charcot's ideas about music and the brain. In this paper, we describe Charcot's ideas regarding music and place them within the historical context of the growing interest in the neurological underpinnings of music abilities that took place in the 1880s.

    2016-04-01

    The need to increase knowledge of global climate change has led to a drive to create long term climatic data sets for countries and smaller regions. With these data sets it is possible to identify patterns in past recent climate and use these to model future climate. The science of historical climatology allows this without having to rely on instrumental data, which may not be available or reliable. Documentary sources usually provide exact dates in which climatic events occur, which can then be utilized to compare to climatic events in neighbouring regions. This study provides the first reconstruction and extended chronology for climate and precipitation for the Albany region in the Eastern Karoo, for 1840-1870, using historical documentary sources. Methodologies were adopted from similar investigations, where any references to the climate were extracted, digitized and categorized according to an index for both rainfall and temperature (Grab and Nash 2010; Nash and Grab, 2010). The data was categorized into an October to September year due to the study site receiving year long rainfall, and final indexes were created for the warm and dry seasons. Droughts that were recorded in this investigation occurred during 1848-1849, 1861-1862, 1862-1863. Floods were identified in 1847-1848, and in 1867-1868. The study site was found to experience significantly drier than wet periods, and the damage described in the accounts from drought was far more severe than that described during periods of flooding. The findings of this study were also compared to several similar studies conducted in neighbouring regions, and a general consistency was found (Grab and Nash 2010; Nash and Grab, 2010; Nash and Endfield, 2002; Vogel, 1989). Further work examining the socio-economic impacts, patterns of locust visitations and comparing modern day to past recent rainfall is also identified.

    From 1853, Japan's policy of isolation began to be eroded; and, following the Meiji restoration of 1868, the country experienced an unprecedented phase of rapid Westernisation and industrialisation. Until the mid-1880s, many Europeans and Americans worked as merchants, bankers, engineers, doctors and educators; but most were soon replaced by the first generation of well-trained Japanese experts. Many of these Westerners were from Scotland, and this article reviews their contributions to the early development of modern Japan.

    The 19th International Conference on Electron Dynamics in Semiconductors, Optoelectronics and Nanostructures (EDISON'19) was held at the Hospedería Fonseca (Universidad de Salamanca, Spain), on 29 June - 2 July, 2015, and was organized by the Electronics Area from the University of Salamanca. The Conference is held biannually and covers the recent progress in the field of electron dynamics in solid-state materials and devices. This was the 19th meeting of the international conference series formerly named Hot Carriers in Semiconductors (HCIS), first held in Modena in 1973. In the edition of 1997 in Berlin the name of the conference changed to International Conference on Nonequilibrium Carrier Dynamics in Semiconductors, keeping the same acronym, HCIS; and finally in the edition of Montpellier in 2009 the name was again changed to the current one, International Conference on Electron Dynamics in Semiconductors, Optoelectronics and Nanostructures (EDISON). The latest editions took place in Santa Barbara, USA, in 2011 and Matsue, Japan, in 2013. Research work on electron dynamics involves quite different disciplines, and requires both fundamental and technological scientific efforts. Attendees to the conference come mostly from academic institutions, belonging to both theoretical and experimental groups working in a variety of fields, such as solid-state physics, electronics, optics, electrical engineering, material science, laser physics, etc. In this framework, events like the EDISON conference become a basic channel for the progress in the field. Here, researchers working in different areas can meet, present their latest advances and exchange their ideas. The program of EDISON'19 included 13 invited papers, 61 oral contributions and 73 posters. These contributions originated from scientists in more than 30 different countries. The Conference gathered 140 participants, coming from 24 different countries, most from Europe, but also with a significant participation

    On 2011 October 8, the Earth crossed dust trails ejected from comet 21P/Giacobini-Zinner in the late 19th and early 20th Century. This gave rise to an outburst in the activity of the October Draconid meteor shower, and an international team was organized to analyse this event. The SPanish Meteor Network (SPMN) joined this initiative and recorded the October Draconids by means of low-light level CCD cameras. In addition, spectroscopic observations were carried out. Tens of multistation meteor trails were recorded, including an extraordinarily bright October Draconid fireball (absolute magnitude -10.5) that was simultaneously imaged from three SPMN meteor observing stations located in Andalusia. Its spectrum was obtained, showing a clear evolution in the relative intensity of emission lines as the fireball penetrated deeper into the atmosphere. Here, we focus on the analysis of this remarkable spectrum, but also discuss the atmospheric trajectory, atmospheric penetration and orbital data computed for this bolide which was probably released during 21P/Giacobini-Zinner return to perihelion in 1907. The spectrum is discussed together with the tensile strength for the October Draconid meteoroids. The chemical profile evolution of the main rocky elements for this extremely bright bolide is compared with the elemental abundances obtained for five October Draconid fireballs also recorded during our spectroscopic campaign but observed only at a single station. Significant chemical heterogeneity between the small meteoroids is found as we should expect for cometary aggregates being formed by diverse dust components.

  9. Living and dying with glaciers: people's historical vulnerability to avalanches and outburst floods in Peru

    2005-07-01

    Human populations worldwide are vulnerable to natural disasters. Certain conditions—such as geographical location or people's income level—can affect the degree to which natural disasters impact people's homes and livelihoods. This paper suggests that vulnerability to natural disasters increases when local people, scientists, and policymakers do not communicate and trust each other. Additionally, a breakdown in interaction and confidence among these groups can disrupt the implementation of sound science or well-intentioned policies. This case study analyzes how local people, scientists, and government officials responded to glacier hazards in Peru's Cordillera Blanca mountain range. Cordillera Blanca glacier retreat since the late-19th century has triggered some of the world's most deadly avalanches and glacial lake outburst floods. Although a Peruvian glaciology and lakes security office has "controlled" 35 Cordillera Blanca glacial lakes, 30 glacier disasters have killed nearly 30,000 people in this region since 1941. A lack of local faith in government officials and scientists as well as the State's failure to follow scientists' warnings about potential disasters have endangered or led to the death of thousands of local residents, many of which remain living in hazard zones today.

    In the paper, an example is presented concerning relationships (which cannot be neglected) between mathematics and other sciences. In particular, the relationship between the tropical mathematics and the humanitarian-economic catastrophe of 17th century (related to slavery of Africans) is considered. The notion of critical state of economy of the 19th century is introduced by using the refined Fisher equation. A correspondence principle for thermodynamics of fluids and economics of the 19th century is presented.

  17. Geometric frustration on a 1/9th site depleted triangular lattice

    2013-03-01

    In the searches both for new spin liquid and spin ice (artificial and macroscopic) candidates, geometrically frustrated two-dimensional spin systems have played a prominent role. Here we present a study of the classical antiferromagnetic Ising (AFI) model on the sorrel net, a 1/9th site depleted and 1/7th bond depleted triangular lattice. The AFI model on this corner-shared triangle net is found to have a large residual entropy per spin S/N = 0 . 48185 +/- 0 . 00008 , indicating the sorrel net is highly geometrically frustrated. Anticipating that it may be difficult to achieve perfect bond depletion, we investigate the physics resulting from turning back on the depleted bonds (J2). We present the phase diagram, analytic expressions for the long range partially ordered ground state spin structure for antiferromagnetic J2 and the short range ordered ground state spin structure for ferromagnetic J2, the magnetic susceptibility and the static structure factor. We briefly comment on the possibility that artificial spin ice on the sorrel lattice could by made, and on a recent report [T. D. Keene et al., Dalton Trans. 40 2983 (2011)] of the creation of a 1/9th depleted cobalt hydroxide oxalate. This work was supported by NSERC (JMH) and NSERC USRA (JJB)

    This special issue of Journal of Micromechanics and Microengineering is devoted to the 19th MicroMechanics Europe Workshop (MME 08), which took place at the RWTH Aachen University, Aachen, Germany, from 28-30 September, 2008. The workshop is a well recognized and established European event in the field of micro system technology using thin-film technologies for creating micro components, micro sensors, micro actuators, and micro systems. The first MME Workshop was held 1989 in Enschede (The Netherlands) and continued 1990 in Berlin (Germany), 1992 in Leuven (Belgium), and then was held annually in Neuchâtel (Switzerland), Pisa (Italy), Copenhagen (Denmark), Barcelona (Spain), Southampton (UK), Ulvik in Hardanger (Norway), Gif-sur-Yvette (France), Uppsala (Sweden), Cork (Ireland), Sinaia (Romania), Delft (The Netherlands), Leuven (Belgium), Göteborg (Sweden), Southampton (UK), and in Guimarães (Portugal). The two day workshop was attended by 180 delegates from 26 countries all over Europe and from Armenia, Austria, Bulgaria, Canada, China, Cuba, Iran, Japan, Korea, Malaysia, Taiwan, Turkey, and the United States of America. A total of 97 papers were accepted for presentation and there were a further five keynote presentations. I am proud to present 22 high-quality papers from MME 2008 selected for their novelty and relevance to Journal of Micromechanics and Microengineering. All the papers went through the regular reviewing procedure of IOP Publishing. I am eternally grateful to all the referees for their excellent work. I would also like to extend my thanks to the members of the Programme Committee of MME 2008, Dr Reinoud Wolffenbuttel, Professor José Higino Correia, and Dr Patrick Pons for pre-selection of the papers as well as to Professor Robert Puers for advice on the final selection of papers. My thanks also go to Dr Ian Forbes of IOP Publishing for managing the entire process and to the editorial staff of Journal of Micromechanics and Microengineering. I

    Placentation disorders are the result of impaired embedding of the placenta in the endometrium. The prevalence of these disorders is estimated to be around 0.3 %. A history of previous prior uterine surgery (especially cesarean section and curettage) is the most common risk factor. Impaired placentation is differentiated into deep placental attachment; marginal, partial and total placenta previa; and placenta accreta, increta and percreta. Treatment depends on the severity of presentation and ranges from expectant management to emergency hysterectomy. In most cases, preterm termination of pregnancy is necessary. We report here on the case of a 39-year-old woman with placenta accreta and total placenta previa who underwent hysterectomy in the 19th week of pregnancy.

    The 19th International Colloquium on Magnetic Films and Surfaces (ICMFS 2006) was held on 14-18 August 2006 at the Sendai International Center in Sendai, Japan. The purpose of the Colloquium was to bring together scientists working on magnetic thin films and surfaces and to provide an opportunity for presentation and discussion of recent experimental and theoretical advances in the field. 285 scientists from 17 countries (Japan: 167, overseas: 118) participated in the Colloquium, as well as 6 family members. There were 56 oral and 178 poster presentations. The oral presentations consisted of 3 plenary talks, 23 invited talks and 30 contributed talks. The number of presentations by scientific category are as follows: Spin dependent transport: 43 Magnetic storage/memory: 9 Magnetization reversal and fast dynamics: 15 Spin injection and spin transfer torque: 26 Magnetic thin films and multilayers: 71 High spin polarization materials: 17 Hard and soft magnetic materials: 3 Magneto-optics: 5 Characterization techniques for thin films and surfaces: 7 Exchange coupling: 13 Micro- and nanopatterned magnetic structures: 18 Micromagnetic modelling: 2 One of the characteristics of the present Colloquium is an increase in the number of presentations in the field of spin-electronics, as seen above. This Cluster Issue of Journal of Physics D: Applied Physics includes several important papers in this rapidly developing field. We believe that, in the future, the field of magnetic materials will maintain its popularity and, on top of that, other fields such as spintronics materials, materials related to life sciences and medicine and also materials related to the environment will be investigated further. The ICMFS Conference started in London in 1964, and is now one of the world-wide conferences on magnetism. The Colloquium has been held in Japan four times now: the previous ones being the 5th ICMFS in the Mount Fuji area, the 10th at Yokohama and the 17th at Kyoto, which was

    Wind tunnel tests were carried out on a 1/9th scale model of the F/A-18 at high angles of attack to investigate the characteristics of tail buffet due to bursting of the wing leading edge extension (LEX) vortices. The tests were carried out at the Aeronautical Research Laboratory low-speed wind tunnel facility and form part of a collaborative activity with NASA Ames Research Center, organized by The Technical Cooperative Program (TTCP). Information from the program will be used in the planning of similar collaborative tests, to be carried out at NASA Ames, on a full-scale aircraft. The program covered the measurement of unsteady pressures and fin vibration for cases with and without the wing LEX fences fitted. Fourier transform methods were used to analyze the unsteady data, and information on the spatial and temporal content of the vortex burst pressure field was obtained. Flow visualization of the vortex behavior was carried out using smoke and a laser light sheet technique.

    2011-01-01

    One of the characteristics of historical analyses of epidemic diseases is the notion of crisis: epidemics are generally perceived as events that do not fit within the framework of everyday order and practices and go beyond individual experiences (suffering, threat of death), jeopardizing social structures, public order, economic activities and moral values. However, epidemic events also shed light on how societies organize healthcare in times of normality, including the extent and limits of the action of health authorities and the role of populations in meeting their own daily needs. This article discusses the organization of healthcare in Minas Gerais province of Brazil during two epidemic episodes, i.e., smallpox (from 1873 to 1875) and cholera (from 1855 to 1856), with the aim of identifying the problems experienced by the population of Minas and the actions taken by the public health authorities during these epidemics. We suggest that the difficulties caused by the arrival of cholera and/or intensification of the smallpox epidemic contributed to expose and exacerbate the shortcomings characterizing healthcare in that society. We also observe that the social mobilization of patients during these events was nothing new, given the low participation of the state in public health during this period, which counted on initiatives and support from civil society.

    Realizing that the Spanish colonies were being devastated by epidemics of smallpox resulting in thousands of deaths, Charles IV, King of Spain, sent one of his court's physicians to apply the recently discovered vaccine. Without refrigeration, the vaccine was passed from one child to another (boys taken out of orphanages). Francisco Xavier de Balmis and a team that included three assistants, two surgeons, and three nurses sailed from Spain on November 30. 1803. They vaccinated more than 100,000 people from the Caribbean Islands and South, Central, and North America, reaching up to San Antonio, Texas, and then traveled to the Philippines, Macao, Canton, and Santa Elena Island, landing back in Cadiz on September 7, 1806. During his journey, Balmis instructed local physicians on how to prepare, preserve, and apply the vaccine, while collecting rare biologic specimens. On the 200th anniversary of their sailing, recognition is given to this group for conducting what was the first global vaccination campaign that reached Texas and California.

    Data sources are achieved records of men workers' passbooks and registry for work permits in two rural parts of Southern France. We obtained three samples: masons from Rancon, a Limousin village, local sedentary alpine workers and Italian immigrants. The results obtained provide two types of information. The first concerns adult height, which is thought to be a result of both a growth pattern and environmental factors. The second concerns growth rates at the end of adolescence. The results seem to contradict the statements made above concerning the relationships between misery, elevation and height. While the alpine inhabitants are shorter, the Limousin inhabitants are taller in sprite they live in a miserable environment. It appears that taller individuals select themselves into migration. Thus, this model would contradict the idea of a regional genetic base.

    Although the contribution to anatomical illustration by Vesalius and his followers has received much attention, less credit has been given to Veslingius and particularly Fabricius. By 1600, Fabricius had amassed more than 300 paintings that together made the Tabulae Pictae, a great atlas of anatomy that was highly admired by his contemporaries. Many of his new observations were incorporated into subsequent books, including those by Casserius, Spighelius, Harvey and Veslingius. Also of importance were the Tabulae by Eustachius (1552), which, although only published in 1714, greatly influenced anatomical wax modelling. In 1742, Pope Benedict XIV established a Museum of Anatomy in Bologna, entrusting to Ercole Lelli the creation of several anatomical preparations in wax. Felice Fontana realised that the production of a large number of models by the casting method would make cadaveric specimens superfluous for anatomical teaching and in 1771 he asked the Grand Duke to fund a wax-modelling workshop in Florence as part of the Natural History Museum, later known as La Specola. Fontana engaged Giuseppe Ferrini as his first modeller and then the 19-year-old Clemente Susini who, by his death in 1814, had superintended the production of, or personally made, more than 2000 models. In 1780, the Austrian Emperor Joseph II visited La Specola and ordered a great number of models for his Josephinum museum; these were made by Fontana with the help of Clemente Susini and supervised by the anatomist Paolo Mascagni. It is, however, in Cagliari that some of Susini's greatest waxes are to be found. These were made when he was free of Fontana's influence and were based on dissections made by Francesco Antonio Boi (University of Cagliari). Their distinctive anatomical features include the emphasis given to nerves and the absence of lymphatics in the brain, a mistake made on earlier waxes. The refined technical perfection of the anatomical details demonstrates the closeness of the cooperation between Susini and Boi, whereas the expressiveness of the faces and the harmony of colours make the models of Cagliari masterpieces of figurative art.

    2012-08-01

    Scurvy has increasingly been recognized in archaeological populations since the 1980s but this study represents the first examination of the paleopathological findings of scurvy in a known famine population. The Great Famine (1845-1852) was a watershed in Irish history and resulted in the death of one million people and the mass emigration of just as many. It was initiated by a blight which completely wiped out the potato-virtually the only source of food for the poor of Ireland. This led to mass starvation and a widespread occurrence of infectious and metabolic diseases. A recent discovery of 970 human skeletons from mass burials dating to the height of the famine in Kilkenny City (1847-1851) provided an opportunity to study the skeletal manifestations of scurvy-a disease that became widespread at this time due to the sudden lack of Vitamin C which had previously almost exclusively been provided by the potato. A three-scale diagnostic reliance approach has been employed as a statistical aid for diagnosing the disease in the population. A biocultural approach was adopted to enable the findings to be contextualized and the etiology and impact of the disease explored. The results indicate that scurvy indirectly influenced famine-induced mortality. A sex and stature bias is evident among adults in which males and taller individuals displayed statistically significantly higher levels of scorbutic lesions. The findings have also suggested that new bone formation at the foramen rotundum is a diagnostic criterion for the paleopathological identification of scurvy, particularly among juveniles.

    This document is a report of observations and results obtained from a lighting demonstration project conducted under the U.S. Department of Energy (DOE) GATEWAY Demonstration Program. The program supports demonstrations of high-performance solid-state lighting (SSL) products in order to develop empirical data and experience with in-the-field applications of this advanced lighting technology. The DOE GATEWAY Demonstration Program focuses on providing a source of independent, third-party data for use in decision-making by lighting users and professionals; this data should be considered in combination with other information relevant to the particular site and application under examination. Each GATEWAY Demonstration compares SSL products against the incumbent technologies used in that location. Depending on available information and circumstances, the SSL product may also be compared to alternate lighting technologies. Though products demonstrated in the GATEWAY program may have been prescreened for performance, DOE does not endorse any commercial product or in any way guarantee that users will achieve the same results through use of these products. This report reviews the installation and use of LED PAR38 lamps to light a collection of toned albument photographic prints at the J. Paul Getty Museum in Malibu, California. Research results provided by the Getty Conservation Institute are incorporated and discussed.

    Microbiological research in the days before specialized equipment, or even electricity, required a great deal of ingenuity. The revival of 90-year-old bioluminescent bacteria from Beijerinck's laboratory in Delft prompted a review of his work with these microorganisms and revealed their use in simple techniques for the investigation of, among other things, sugar metabolism in yeasts, oxygen generation and uptake and even the survival of microorganisms in liquid hydrogen. He used variant strains of bioluminescent bacteria in an attempt to study heredity and variation in biological systems and described one of the earliest examples of enzyme induction.

    Adolph Hannover (1814-94), Danish anatomist and pathologist, introduced the microscopy to the medical research in Denmark. He published several papers on anatomy and pathology, among others Om Mikroskopets Bygning og dets Brug (1847) which was translated to several European languages, among others to English On the structure of the microscope and its use. As a jew he never succeeded in obtaining a post at the University of Copenhagen, Ib Pedersen Ibsen (1801-62) was educated at the Academia Chirurgorium Regia, the college of surgeons in Copenhagen, and he never became a scholarly anatomist, writing one paper only, published after his death. He was a competent anatomist and an appreciated teacher. The two anatomists competed for a post as lecturer in anatomy at the University of Copenhagen. Ibsen obtained the job after a public competition. The Museum of Medical History in Copenhagen is in possession of Ibsen's own copy of Hannover's dissertation on the cartilage, the muscles and the nerves of the external ear. In this copy Ibsen by hand has written some critical and unkind remarks against Hannover. Was this a sign of hostility? We conclude that they hardly were friends, but that the language between colleagues at the university could be rather harsh at that time.

    Allegedly kidnapped from a secret city in Central America, the "Aztec children" began a showman's career in the early-1850s. They died around 1900, after being observed by countless pathologists and ethnologists from Europe and the US. Most of the literature on the "Aztec children" has emphasized racial theories, the imperial gaze, and the character of "ethnological shows", where monstrosity and ethnicity were practically synonymous. Less attention has been paid to the fact that scientists continuously insisted that the case was false, an argument that instead of debunking the myth of the "Aztec children", contributed to establishing the "Aztecs" as "a matter of fact". In examining the case of the "Aztec children", this essay aims to explore what can be called the shifting nature or elusiveness of falsehood.

    Pollen and X-ray fluorescence spectrometry (XRF) analyses from a 272 cm-long sediment core of Lago Amapá, an oxbow lake in western Amazonia, reveal the first palaeoecological investigation of late Holocene sediments in Acre state, Brazil. Radiocarbon dating of older sediments failed due to re-deposition of organic material but a historical map suggests that lacustrine deposition started at 1900 AD. We detected two periods of changes in sediment and vegetation, dominated by pioneer taxa especially Cecropia. The first period around 1900 AD is documenting an initial oxbow lake, with regular fluvial input (high Ti) and low accumulation of organic matter (low inc/coh ratio). During that period Andean pollen taxa originating from Peruvian Andean headwaters were deposited. A fully lacustrine phase started about 1950 AD and is characterized by prolonged periods of stagnant water (low Fe/Mn ratio). The increase of pioneer taxa, sedimentation rates and a reduction of most of the XRF element counts point to a period during which Lago Amapá was a more isolated lake which was flooded only during exceptional severe flood events and is catching mainly anthropogenic disturbances. The extensive human influence during this period was assumed by 1) the high occurrence of pioneer taxa and the absence of charcoal which could indicate changes in vegetation possibly as a result of logging, 2) the Ca and Ti/K ratio which reflect changes to a local sediment source, and 3) comparison of Landsat images from the last 30 years which shows broad changes in vegetation cover and land transformation in the peripheral areas of the oxbow lake.

    Peter Mark Roget (1779-1869) is best known for his Thesaurus, a project completed late in his long life. He trained as a physician, practiced medicine, and was interested in many branches of science. Much of his life was dedicated to the systematization of knowledge and identifying relationships. Although not an experimentalist in the modern sense of the word, he contributed to "neuroscience" in journal and encyclopaedia articles, as well as in books and lectures. He wrote extensively on comparative physiology, sensory systems, phrenology, optics, and various disorders affecting the nervous system. He viewed his two-volume Bridgewater Treatise of 1834 as his most significant achievement, turning to physiology and comparative anatomy to argue that God's existence can be seen in how living forms and their components are designed. Roget was active in many scholarly organizations, most notably the Royal Society of London, where he served for more than two decades as its secretary before "retiring" to pursue his Thesaurus.

  4. Radio outbursts in extragalactic sources

    NASA Astrophysics Data System (ADS)

    Kinzel, Wayne Morris

    Three aspects of the flux density variability of extragalactic radio sources were examined: millimeter wavelength short timescale variability, the spectral evolution of outbursts, and whether the outbursts are periodically spaced. Observations of extragalactic radio sources were conducted using the Five College Radio Astronomy Observatory between January and June 1985 at 88.2 GHz and during June and July 1985 at 40.0 GHz. Many of the sources exhibited significant flux density variations during the observing span. In addition, the most rapid variations observed were comparable with those reported in previous works. Two sources, 0355+50 and OJ287, both exhibited outbursts whose rise and fall timescales were less than a month. An anomalous flux density dropout was observed in 3C446 and was interpreted as an occultation event. Data at five frequencies between 2.7 and 89.6 GHz from the Dent-Balonek monitoring program were used to investigate the spectral evolution of eight outbursts. Outburst profile fitting was used to deconvolve the individual outbursts from one another at each frequency. The fit profiles were used to generate multiple epoch spectra to investigate the evolution of the outbursts. A phase residual minimization method was used to examine four sources for periodic behavior.

    Thousands of mine workers die every year from mining accidents, and instantaneous coal outbursts in underground coal mines are one of the major killers. Various models for these outbursts have been proposed, but the precise mechanism is still unknown. We hypothesize that the mechanism of coal outbursts is similar to magma fragmentation during explosive volcanic eruptions; i.e., it is caused by high gas pressure inside coal but low ambient pressure on it, breaking coal into pieces and releasing the high-pressure gas in a shock wave. Hence, coal outbursts may be regarded as another type of gas-driven eruption, in addition to explosive volcanic, lake, and possible ocean eruptions. We verify the hypothesis by experiments using a shock-tube apparatus. Knowing the mechanism of coal outbursts is the first step in developing prediction and mitigation measures. The new concept of gas-driven solid eruption is also important to a better understanding of salt-gas outbursts, rock-gas outbursts, and mud volcano eruptions.

  6. ACCRETION OUTBURSTS IN CIRCUMPLANETARY DISKS

    We describe a model for the long-term evolution of a circumplanetary disk that is fed mass from a circumstellar disk and contains regions of low turbulence (dead zones). We show that such disks can be subject to accretion-driven outbursts, analogous to outbursts previously modeled in the context of circumstellar disks to explain FU Ori phenomena. Circumplanetary disks around a proto-Jupiter can undergo outbursts for infall accretion rates onto the disks in the range M-dot{sub infall} approx. 10{sup -9} to 10{sup -7} M{sub Sun} yr{sup -1}, typical of accretion rates in the T Tauri phase. During outbursts, the accretion rate and disk luminosity increases by several orders of magnitude. Most of the planet mass growth during planetary gas accretion may occur via disk outbursts involving gas that is considerably hotter than predicted by steady state models. For low infall accretion rates M-dot{sub infall} {approx}< 10{sup -10} M{sub sun} yr{sup -1} that occur in late stages of disk accretion, disk outbursts are unlikely to occur, even if dead zones are present. Such conditions are favorable for the formation of icy satellites.

    A Jupiter-family comet, 17P/Holmes, underwent outbursts in 1892 and 2007. In particular, the 2007 outburst is known as the greatest outburst over the past century. However, little is known about the activity before the outburst because it was unpredicted. In addition, the time evolution of the nuclear physical status has not been systematically studied. Here, we study the activity of 17P/Holmes before and after the 2007 outburst through optical and mid-infrared observations. We found that the nucleus was highly depleted in its near-surface icy component before the outburst but that it became activated after the 2007 outburst. Assuming a conventional 1 μm sized grain model, we derived a surface fractional active area of 0.58% ± 0.14% before the outburst whereas the area was enlarged by a factor of ∼50 after the 2007 outburst. We also found that large (≥1 mm) particles could be dominant in the dust tail observed around aphelion. Based on the size of the particles, the dust production rate was ≳170 kg s{sup –1} at a heliocentric distance of r{sub h} = 4.1 AU, suggesting that the nucleus was still active around the aphelion passage. The nucleus color was similar to that of the dust particles and average for a Jupiter-family comet but different from that of most Kuiper Belt objects, implying that color may be inherent to icy bodies in the solar system. On the basis of these results, we concluded that more than 76 m of surface material was blown off by the 2007 outburst.

    Development of a mechanism explaining the internal source of energy of comet outbursts. A mechanism is proposed which automatically provides a source of particulate matter which creates a huge surface area which contains a substantial percentage of amorphous ice, so that the phase transition of the amorphous ice to a cubic structure provides a release of energy which may be responsible for the outbursts observed in many comets. In addition, the volume into which the transition can propagate is estimated for a spherical comet with a radius of 5 km.

    Mountain societies are in a crucial transition phase in terms of the management of natural hazards. Advances in geographic technologies, such as a variety of remote-sensing tools and mobile communication systems, have drastically changed the way of early warning methods in difficult accessible high mountain environments compared to those of ancient times. In order to implement new natural hazard policies, it is essential to unravel the traditional ways of disaster management which is presented here by a case study from the Hindukush-Karakoram-Himalayas. In the rugged relief of the Himalaya Region, the exchange of information was a labor-intensive and time-consuming task for remote high mountain villages before the infrastructural development and the introduction of modern communication systems. Therefore, early warning of natural hazards with long run-out distances seems to have been rather impossible. However, in the present study a historical optical long-distance and fast operating communication system over horizontal distances of several hundred kilometers was discovered during field investigations in the Hindukush-Karakoram and the transmission paths reconstructed in the following years. The so called Puberanch-system relied on a chain of fire signals as used by ancient societies in other mountain and coastal environments in the world. It was originally in use for the alert against war attacks from hostile neighboring communities. Later on, it served as an early warning system for glacier lake outbursts, which have been in the end of the 19th century and beginning of the 20th century one of the most devastating natural hazards in the region. Remarkable is the fact that fire posts were located in extremely harsh environments at altitudes above 4000 m requiring a highly sophisticated supply system of fire wood and food. Interviews with local inhabitants, the evaluation of historical travel records and international newspapers proved, that the system has been

    Birds occupy a prominent place in the Brazilian economy not only in the poultry industry but also as an animal model in many areas of scientific research. Thus the aim of this study was to provide a description of macro and microscopic aspects of the ectoderm-derived structures in chicken embryos / fetuses poultry (Gallus gallus domesticus) from 1st to 19th day of incubation. 40 fertilized eggs, from a strain of domestic chickens, with an incubation period of 2-19 days were subjected to macroscopic description, biometrics, light, and scanning microscopy. All changes observed during the development were described. The nervous system, skin and appendages and organs related to vision and hearing began to be identified, both macro and microscopically, from the second day of incubation. The vesicles from the primitive central nervous system-forebrain, midbrain, and hindbrain-were identified on the third day of incubation. On the sixth day of incubation, there was a clear vascularization of the skin. The optic vesicle was first observed fourth day of development and on the fifth day there was the beginning of the lens formation. Although embryonic development is influenced by animal line as well as external factors such as incubation temperature, this paper provides a chronological description for chicken (Gallus gallus domesticus) during its embryonic development.

    Magnetars have been observed to increase their flux output by several orders of magnitude in outbursts. Following outbursts they cool on timescales of months to years. We propose to observe two magnetars, Swift J1822.3-1606 and 1E 1547.0-5408, using Chandra as they approach their quiescent state following their recent outbursts in 2011 and 2009, respectively. We will apply a newly developed crustal cooling model to these cooling curves to constrain the properties of the magnetars, such as the crust thickness and heat capacity, and of their outbursts, such as the location of energy deposition.

  12. Outbursts and cavities in comets

    NASA Astrophysics Data System (ADS)

    Ipatov, Sergei

    Based on analysis of the images made during the first 13 minutes after the collision of the impact module of the Deep Impact (DI) spacecraft with Comet 9P/Tempel 1, Ipatov & A'Hearn [1] studied time variations of ejection of material after this impact. They showed that, besides the normal ejection, at time t_{e} after the DI collision between 8 s and 60 s there was a considerable additional ejection (a triggered outburst) of small (micron size) particles. It increased the mean velocities of observed small ejected particles (compared with the normal ejection). The outburst could be caused by excavation of a large cavity with dust and gas under pressure. The largest cavity excavated after the collision could be relatively deep because a considerable excess ejection lasted during about 50 s. Schultz et al. [2] concluded that the diameter d_{tc} of the DI transient crater was about 200 m. Some authors support smaller values of d_{tc}. The depth of the DI crater at t_{e}=8 s was estimated in [3] to be about 6 m for d_{tc}=200 m and 4 m for d_{tc}=100 m. The distance between the pre-impact surface of Comet 9P/Tempel 1 and the upper border of the largest excavated cavity equal to about 4-6 m, and sizes of particles inside the cavities of a few microns are in good agreement with the results obtained by Kossacki & Szutowicz [4]. In their models of the explosion of Comet 17P/Holmes, the initial sublimation front of the CO ice was located at a depth of 4 m, 10 m, or 20 m, and calculations were finished when the CO pressure exceeded the threshold value 10 kPa. It was shown that the pressure of CO vapor can rise to this value only when the nucleus is composed of very fine grains, a few microns in radius. The porous structure of comets provides enough space for sublimation. The projection of the velocity of the leading edge of the DI cloud (onto the plane perpendicular to the line of sight) was about 100-200 m/s and is typical for outburst particles ejected from comets

    The 19th Europhysics Sectional Conference on the Atomic and Molecular Physics of Ionized Gases (ESCAMPIG-2008) took place in Granada (Spain) from 15 to 19 July 2008. The conference was mainly organized by the Spanish National Research Council (CSIC), with the collaboration and support of the University of Córdoba (UCO) and the Research Center for Energy, Environment and Technology (CIEMAT). It is already 35 years since the first ESCAMPIG in 1973. The first editions of ESCAMPIG were in consecutive years (1973 and 1974) but later on it became a biennial conference of the European Physical Society (EPS) initially focusing on the collisional and radiative atomic and molecular processes in low temperature plasmas. The successive ESCAMPIGs took place in Bratislava in 1976 (3rd), Essen in 1978 (4th), Dubrovnik in 1980 (5th) and so on until the last one organized in Granada in 2008 (19th), the first ESCAMPIG in Spain. A number of changes have taken place in the Granada edition of ESCAMPIG. First, the previous six topics that have remained unchanged for almost two decades (since 1990) have now been updated to become twelve new topics which, in the opinion of the International Scientific Committee (ISC), will enhance the opportunity for discussions and communication of new findings and developments in the field of low temperature plasmas. The new list of topics for ESCAMPIG is: • Atomic and molecular processes in plasmas • Transport phenomena, particle velocity distribution function • Physical basis of plasma chemistry • Plasma surface interaction (boundary layers, sheath, surface processes) • Plasma diagnostics • Plasma and dicharges theory and simulation • Self-organization in plasmas, dusty plasmas • Upper atmospheric plasmas and space plasmas • Low pressure plasma sources • High pressure plasma sources • Plasmas and gas flows • Laser produced plasmas Secondly, a new prize has been created, the `William Crookes' prize in Plasma Physics to be

    Borges, B. W.; Baptista, R.

    2006-06-01

    In this work, we report the eclipse mapping analysis of CCD photometric data of two short period dwarf novae - V4140 Sgr (Borges & Baptista 2005) and HT Cas (Borges, Baptista & Catalán, in preparation) - during observed outburst events. The analysis of the observations of V4140 Sgr, done between 1991 and 2001, reveals that the object was in the decline from an outburst in 1992 and again in outburst in 2001. A distance of d = 170+/-30 pc is obtained from a method similar to that used to constrain the distance to open clusters. From this distance, disc radial brightness temperature distributions are determined, and the disc temperatures remain below the critical effective temperature T_{crit} at all disc radii during the outburst. The distributions in quiescence and in outburst are significantly different from those of other dwarf novae of similar orbital period. These results cannot be explained within the framework of the disc instability model and the small amplitude outbursts of V4140 Sgr can be due bursts of enhanced mass transfer rate from the secondary star. Our HT Cas data consist of V and R CCD photometric observations done in 2005 November with the 0.95-m James Gregory Telescope (JGT) and cover a outburst cycle. We used the entropy associated to the eclipse maps to obtain the semi-opening disc angle α evolution throught the outburst. The obtained angles are systematically lower than those obtained by Ioannou et al. (1999) and we can conclude that the outburst radial profiles must be flatter than the the T ∝ r^{-3/4} law of steady state dics, against the expectations of the disc instability model. Our intensity radial distributions presents the same ``outside-in'' outburst behavior as obtained by the referred author.

    The army medical officer, Felipe Ovilo Canales, was a prominent and representative figure in colonialist projects in Morocco during the Restoration. Unlike other European powers, Spain's colonial missions were mainly aimed at fostering and controlling the ongoing process of Moroccan administrative reform. In the context of this overall reform strategy, Ovilo developed a political discourse that affirmed the historic convergence of Spanish and Moroccan interests; he played a leading role in Moroccan public health through the Tangiers Health Authority and the Tangiers School of Military Medicine. Finally, he formulated a racial discourse on the "Moors" that was based on historical and moral rather than biological criteria.

  20. [The pure being of writing. Ecriture automatique in 19th century psychiatry and early surrealism (Breton/Soupault: Les champs magnétiques)].

    PubMed

    Bergengruen, Maximilian

    2009-03-01

    Ecriture automatique and psychoanalysis are often lumped together in literary studies, almost as a knee-jerk reaction. However, on closer inspection it can be seen that the discoverers of automatic writing--the surrealists--were more interested in the hysteria research that prevailed around the year 1900 (Pierre Janet, Alfred Binet) and in parapsychology (Frederic Myers). In these two branches of medicine, the theory and practice of automatic writing are based on an experimental constellation in which the relationship between the psychiatrist/experiment organiser and the patient/participant takes centre stage. Here, the latter writes in response to an order or question from the former, mostly while overcoming a physical or memory block. André Breton and Philippe Soupault set up a very similar constellation in the Champs magnétiques, though with some key alterations. Indeed, surrealism liberates the patient engaging in automatic writing from the dictates of the psychiatrist--but only to submit him to a yet more overwhelming force, a pure violence of writing, so to speak: the automatism of a 'higher reality'.

  1. Structure of "Ventilation and Warming" in Notes on Nursing Written by Florence Nightingale in 19th Century: Introduction of Basic Physics to Nursing Students

    NASA Astrophysics Data System (ADS)

    Ogoh, Kazutoshi

    "Basic Natural Science" for freshmen at Miyazaki Prefectural Nursing University has a component including physics. Here students learn three principles of thermal transfer; conduction, radiation, and convection through a series of experiments. The purpose of these experiments is to understand the structure of a method for the caring of breathing and temperature of patients as written in "Ventilation and Warming", the first chapter of F. Nightingale's Notes on Nursing. Students can then apply this structure to retain fresh air in today's hospital rooms, and can then appreciate studying real physics incorporated into fundamental knowledge for nursing practice.

    Both wound healing and lymphedema have fibrosis of the skin in common. They also share destruction of elastin by elastases from neutrophils as a significant feature. These are not new observations, and the writings of Unna and Kaposi are recalled. The contemporary observations on elastin by Gerli and his team are discussed in the light of these much earlier opinions.

  3. Flood magnitudes in the Tagus River (Iberian Peninsula) and its stochastic relationship with daily North Atlantic Oscillation since mid-19th Century

    This paper presents a new methodological approach in the analysis of the influence of the North Atlantic circulation on the flood magnitude of the Tagus River, the largest Atlantic draining river of the Iberian Peninsula. This methodology is based on Correspondence Analysis viewed as a qualitative regression tool. A daily scale database (sea level atmospheric pressure, river discharge, rainfall) was used for this study. The selected streamflow station, Vila Velha de Rodão (Portugal, near the Spanish border), holds the longest continuous daily river discharge register of the Iberian Peninsula (over 160 years, since 1852). The annual maximum flood magnitudes were classified into seven categories according to their specific recurrence intervals (T). The qualitative regression approach was used to relate annual peak flood occurrence with the North Atlantic Oscillation (NAO) index mode (positive or negative) registered, during the preceding 40 days (divided in 8 successive 5-day periods). Large floods (categories 1-2 of T > 50 years and category 3, T ˜25-50 years) were found to be associated with a very high frequency of the negative NAO mode during the initial 20-25 days (within a total 40 days period length) before de flood peak. The lack of significant association of these flood categories with a predominant NAO mode during the immediately preceding 15 days, prior to the flood, suggest a time lag of 15 days before the peak. Minor flooding (category 7, T < 2 years) show a high degree of association with the presence of a positive NAO mode during the previous 20-25 days. The analysis of flood response under natural and dam-regulated regimes (before and after the construction of dams ca 1960) revealed no changes in the behaviour of major floods (responding to a period of 25 days with a dominant negative NAO index mode). Moderate flooding of category 4 (T: 10-25 years), that during the pre-dam construction period were linked to the existence of an initial 5-15 days of negative NAO mode, were not documented during the post-dam period, probably due to flood peak discharge attenuation by reservoirs. The clear climatic control (rainfall accumulation and number of persisting NAO negative mode days) in the onset of flood category 3 (T: 25-50 years) was also statistically blurred during the post-dam period, due to the effective role of dam operation in flood management during wet winters. This dam management effect does not seem to mask the meteorologically related largest flood magnitude events (T > 50 years), indicating that catastrophic events will likely occur under the NAO negative daily and seasonal patterns defined in this work. The robustness of the model was assessed by the phenomenological analysis of misclassified Flood/NAO events. Results also indicate that flood management practises may benefit from improved climate scenarios and forecasting of the NAO index.

  4. “Phossy Jaw” and “Bis-phossy Jaw” of the 19th and the 21st Centuries: The Diuturnity of John Walker and the Friction Match

    Some 200 years ago, workers developed gingivitis, periodontal disease, alveolar crest bone sequestra, and draining fistulae after exposure to phosphorous fumes and phosphorous paste in the manufacture of the friction match. Many also suffered loss of teeth and pathologic fracture of the mandible. Known as “phossy jaw,” the constellation rather abruptly vanished following the International Berne Convention of 1906. Today, “bis-phossy jaw” (bisphosphonate-induced osteonecrosis of the jaw) has surfaced with pathologic fractures and other features common to its predecessor, “phossy jaw.” This modern equivalent is reported with ever-increasing frequency and is presented here in the format of a brief historical review and a case report that includes segmental en bloc extirpation of necrotic mandible and pain-free salvage. Computerized imagery and three-dimensional printing technology were successfully chosen to create and apply a custom titanium bone plate, without free-tissue transfer. PMID:27053988

  5. Coupled Socio-Environmental Changes Triggered Indigenous Aymara Depopulation of the Semiarid Andes of Tarapacá-Chile during the Late 19th-20th Centuries

    Socio-economic and environmental changes are well known causes of demographic collapse of agrarian cultures. The collapse of human societies is a complex phenomenon where historical and cultural dimensions play a key role, and they may interact with the environmental context. However, the importance of the interaction between socio-economic and climatic factors in explaining possible breakdowns in Native American societies has been poorly explored. The aim of this study is to test the role of socio-economic causes and rainfall variability in the collapse suffered by the Aymara people of the semiarid Andean region of Tarapacá during the period 1820–1970. Our motivation is to demonstrate that simple population dynamic models can be helpful in understanding the causes and relative importance of population changes in Andean agro-pastoral societies in responses to socio-environmental variability. Simple logistic models that combine the effects of external socio-economic causes and past rainfall variability (inferred from Gross Domestic Product [GDP] and tree-rings, respectively) were quite accurate in predicting the sustained population decline of the Aymara people. Our results suggest that the depopulation in the semiarid Tarapacá province was caused by the interaction among external socio-economic pressures given by the economic growth of the lowlands and demands for labor coupled with a persistent decline in rainfall. This study constitutes an example of how applied ecological knowledge, in particular the application of the logistic equation and theories pertaining to nonlinear population dynamics and exogenous perturbations, can be used to better understand major demographic changes in human societies.

  6. An international campaign of the 19th century to determine the solar parallax. The US Naval expedition to the southern hemisphere 1849-1852

    In 1847 Christian Ludwig Gerling, Marburg (Germany), suggested the solar parallax to be determined by measuring the position of Venus close to its inferior conjunction, especially at the stationary points, from observatories on nearly the same meridian but widely differing in latitude. James M. Gilliss, astronomer at the newly founded U.S. Naval Observatory, enthusiastically adopted this idea and procured a grant for the young astronomical community of the United States for an expedition to Chile. There they were to observe several conjunctions of Venus and oppositions of Mars, while the accompanying measurements were to be taken at the US Naval Observatory in Washington D.C. and the Harvard College Observatory at Cambridge, USA. This expedition was supported by A.V. Humboldt, C.F. Gauß, J.F. Encke, S.C. Walker, A.D. Bache, B. Peirce and others. From 1849 to 1852 not only were astronomical, but also meteorological and magnetic observations and measurements recorded, mainly in Santa Lucia close to Santiago, Chile. By comparing these measurements with those taken simultaneously at other observatories around the world the solar parallax could be calculated, although incomplete data from the corresponding northern observatories threatened the project's success. In retrospect this expedition can be recognized as the foundation of the Chilean astronomy. The first director of the new National Astronomical Observatory of Chile was Dr. C.W. Moesta, a Hessian student of Christian Ludwig Gerling's. The exchange of data between German, American and other astronomers during this expedition was well mediated by J.G. Flügel, consul of the United States of America and representative of the Smithsonian Institution in Europe, who altogether played a major role in nurturing the relationship between the growing scientific community in the U.S. and the well established one in Europe at that time.

    Massage and medical gymnastics are very ancient form of medical practices and knowledge, nevertheless they seem to focus a growing attention between 1860 and World War I in Europe. These practices know a quick institutionalization, and the physiotherapy or "kinesitherapy" emerge as a discipline with some more structured training course for students and future practitioners. In fact, the determinants of this development are numerous, specialization, professionalization, cultural transfer, and more broadly with geopolitical influences and nationalist feelings, influence of the Swedish gymnastics.

    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.

  9. Adjusting Astronomical Practices: The ``Carte du Ciel'', the democratic rules and the circulation of opinions at the end 19th century

    Launched in 1887, the ``Carte du Ciel'' was an international project aiming at photographing the entirety of the celestial vault. Tasks required for this huge undertaking were divided among 18 observatories around the globe. Instruments were standardized and a series of international conferences established operating modes and prescribed norms to be followed everywhere. In each observatory, however, the drive toward uniformity ran into a variety of minor technical and practical problems. In this paper, we examine the strategies mobilized by observers to tinker with stated rules and adapt them to their own experience as astronomers. To underscore the tension between normative prescriptions and individual practices, we consider the Bulletin of the Permanent International Committee for the execution of the Carte du Ciel as an informal forum where various queries raised and arrangements adopted were shared among the scientific community.

  10. Grape harvest dates as indicator of spring-summer mean maxima temperature variations in the Minho region (NW of Portugal) since the 19th century

    This paper reports a climatic reconstruction approach for the Minho region (NW of Portugal) using grape harvest dates (GHD) as proxy of surface air temperature. This new GHD series was built based on the records from a set of local and regional newspapers (1854-1978) and the annuals of a Wine Producers Cooperative (1978-2010). The strong inverse correlation between Minho GHD and the mean maxima temperatures of the preceding March to August months (GSTmax), registered at the Braga weather station for the overlap period 1941-2009, allowed a reconstruction, with associated statistical uncertainties, of the regional GSTmax back to 1856. These were then used to characterize the main climatic episodes in the region during the last 154 years. The most noticeable feature that emerges from the comparison of the Minho GSTmax with the global annual average temperatures of Jones et al. (2013) is that these regional temperatures, in clear contrast with the global warming observed from around 1990 onwards, show no noteworthy increasing trend. The influence of climatic variability was examined also in terms of the relations between GSTmax (1950-2009) and the main meteorological teleconnection patterns affecting the North Atlantic European sector where the Minho region is included. Data support the hypothesis that persistent positive modes of spring-summer Scandinavian (SCA) and summer East Atlantic/Western Russia patterns triggered lower GSTmax, especially in the 60s-80s. The search for solar imprints in the Minho region climate identified the SCA mode as a promising connection between the two, since it is significantly inversely correlated with both, the TSI and the GSTmax. Like in other traditional European viticultural regions, the Minho GHD have shown to be a valuable tool for understanding the interactions between large-scale circulation modes and regional/local climatic conditions. Besides it will deliver a reliable assessment of climatic proxies from geological record, like tidal marsh benthic foraminifera assemblages.

  12. The pole tide/14-month oscillations in the Baltic Sea during the 19th and 20th centuries: Spatial and temporal variations

    Sea level changes with a period of 14 months (P14) are usually associated with the pole tide, which is the oceanic response to the Chandler wobble in the Earth's axis of rotation. The amplitudes of these changes in the Baltic Sea are anomalously large, much larger than follows from the equilibrium pole tide theory. It appears that the oscillations are related to meteorological forcing rather than to pole motions. To examine the P14 properties, we used long-term (48-213 years) tide gauge records from 77 stations located in the Baltic Sea and adjacent area of the North Sea. High-resolution sea level spectra revealed a cluster of peaks with periods from 410 to 450 days. The temporal variations in the P14 sea level amplitudes and peak frequencies are found to be considerable and poorly correlated with the modulation of the Earth's pole motions. In contrast, our findings for 1871-2011 demonstrate strong resemblance between temporal (year-to-year) variations of the P14 peak and zonal wind, confirming earlier results of Ekman (1996) and O'Connor et al. (2000), who indicated the major role of the zonal wind in formation of the 14-month oscillations in the Baltic and North seas. The integral amplitudes of the P14 oscillations in the Baltic Sea gradually increase eastward from the entrance (the Danish straits) to the farthest ends of the sea with the largest amplitudes (up to 6.5 cm) observed at the very head of the Gulf of Finland. Similar P14 amplification toward the west coast of Denmark is also observed along the south coast of the North Sea. The geographical distribution of the P14 in these two regions are almost the same as of the seasonal sea level oscillations, indicating presumably similar formation mechanisms. Extensive shallow-water areas in the Baltic Sea and southeastern part of the North Sea, combined with intense meteorological forcing, appear to be two key factors responsible for the formation of anomalously strong 14-month oscillations in these regions.

    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.

    In an investigation of the artists' materials used by P. S. Krøyer the contents of the tube colours found in Krøyer's painting cabinet were examined. In most cases, the results of the pigment analyses were as expected based on our knowledge of artists' colours used in the late 1800s and early 1900s. However, in one of the tube colours labelled "Jaune de Cadmium Citron" (cadmium lemon yellow) an extremely rare cadmium chromate pigment was found. The pigment was analysed and characterised by Raman microscopy (MRS), scanning electron microscopy-energy dispersive X-ray spectroscopy (SEM-EDS), attenuated total reflectance-Fourier transform infrared spectroscopy (ATR-FTIR), powder X-ray diffraction (PXRD), single-crystal X-ray crystallography, and electron paramagnetic resonance (EPR) spectroscopy. Cadmium chromate was synthesised by precipitation from an aqueous solution of cadmium nitrate and potassium chromate, and the resulting yellow crystals proved identical to the pigment found in the tube colour "Jaune de Cadmium Citron". The structure determined by single-crystal X-ray diffraction identified the pigment as 2CdCrO4·KOH·H2O or more accurately as KCd2(CrO4)2(H3O2) illustrating the μ-H3O2- species. The yellow colour of the paint sample taken from the tube had a greenish hue, which became even more prominent upon storage and drying. EPR analysis of the sample showed the presence of paramagnetic degradation products containing Cr(III) and Cr(V).

    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.

  20. The survival of 19th-century scientific optimism: the public discourse on science in Belgium in the aftermath of the Great War (ca. 1919-1930).

    PubMed

    In historiography there is a tendency to see the Great War as marking the end of scientific optimism and the period that followed the war as a time of discord. Connecting to current (inter)national historiographical debate on the question of whether the First World War meant a disruption from the pre-war period or not, this article strives to prove that faith in scientific progress still prevailed in the 1920s. This is shown through the use of Belgium as a case study, which suggests that the generally adopted cultural pessimism in the post-war years did not apply to the public rhetoric of science in this country. Diverse actors -- scientists, industrialists, politicians, the public opinion, and the military staff -- declared a confidence in science, enhanced by wartime results. Furthermore, belief in science in Belgium was not affected by public outcry over the use of mustard gas, unlike in the former belligerent countries where the gas became an unpleasant reminder of how science was used during the war. Even German science with its industrial applications remained the norm after 1918. In fact, the faith in science exhibited during the pre-war years continued to exist, at least until the 1920s, despite anti-German sentiments being voiced by many sections of Belgian society in the immediate aftermath of the war.

  1. Sociology and positivism in 19th-century France: the vicissitudes of the Société de sociologie (1872-4).

    PubMed

    Heilbron, Johan

    2009-10-01

    Little is known about the world's first sociological society, Emile Littré's Société de Sociologie (1872-4). This article, based on prosopographic research, offers an interpretation of the foundation, political-intellectual orientation and early demise of the society. As indicated by recruitment and texts by its founding members, the Société de Sociologie was in fact conceived more as a political club than a learned society. Guided in this by Littré's heterodox positivism and the redefinition of sociology he proposed around 1870, the Société de Sociologie was intended first and foremost to accompany intellectually the political changes that Littré considered imperative in the early years of the Third Republic (1870-1940). This expectation found little echo among the members of the society, and it seems possible that Littré himself and his closest associates were the ones to interrupt the society's meetings. Some of its members' general studies on the status of the social sciences and their main divisions were continued in the framework of the journal "La Philosophie positive" (1867-83), but the authors most committed to those studies were on the margins of the Littré network. Neither the dominant positivist republicanism, centered around Littré and Dubost, nor the general sociology of the more peripheral members of the network (Mesmer, Roberty, Vitry) represented an important intellectual contribution to the formation of academic sociology in France. Given that the Société de Sociologie did contribute to diffuse the project of a sociological science and developed forms of sociology coherent enough to be rejected by the pioneers of university sociology, the group constitutes a significant case of failure in the history of the discipline.

    The beginnings of modern western medicine reach to about 1800 when under the liberating influence of French Revolution observation of diseases was started to follow more scientifically justified criteria. At that time speculative doctrines prevailed, e. g. those set up natural philosopher Schelling. In this context Internist Friedrich Theodor von Frerichs at Berlin Charité University Hospital gained great merits because of his struggle for a scientifically-based experimental clinical medicine. This is demonstrated nicely in a recently found autograph document.

  4. Charles Darwin and Captain Moresby on the Drowning of Great Chagos Bank: 19th century discovery of “aseismic” ridge seismicity in the Indian Ocean

    NASA Astrophysics Data System (ADS)

    Schlanger, Seymour O.; Stein, Seth A.

    Charles Darwin's reading of Lyell's Principles of Geology and his own observations, made during the voyage of the H.M.S. Beagle, on earthquakes, the elevation of the west coast of South America, and the thick sections of marine strata in the Andean Cordillera led him to “. . . reflect much on the effects of subsidence . . .” with the result that he developed his subsidence theory of atoll formation before he ever saw an atoll. In 1836, during his first visit to an atoll, Keeling Island (now Cocos Island) in the Indian Ocean, he observed evidence of recent subsidence. Reports of a severe earthquake at Keeling in 1834 and two lesser ones in the preceding 10 years led him to conclude that small downward movements had recently taken place. However, it was not until he returned to England and became familiar with the hydrographic surveys of Captain Moresby and the latter's accounts of frequent earthquakes on the Great Chagos Bank that Darwin became convinced that the drowned reefs at Chagos, which now lie 6 to 8 fathoms beneath the surface, appeared “ . . . as if they had been carried down by one uniform movement,” the implication being that the earthquakes were accompanied by subsidence of the Great Chagos Bank. The observations of Darwin and Moresby on earthquakes and tectonics on an “aseismic” ridge are in accord with modern interpretations of “intraplate tectonics” of the Indian Ocean. In particular, earthquakes up to magnitude 7, which occur on the Chagos-Laccadive Ridge, show normal faulting on an east-west fault plane that intersects the Great Chagos Bank and can cause vertical slip of several meters. The work of Darwin and Moresby 150 years ago showed that atolls and their associated drowned banks are sensitive recorders of “intraplate tectonics.”

    During the summer of 1837 Christian Ludwig Gerling, a former student of Carl Friedrich Gauß's, organized the world wide first determination of the deflection of the vertical in longitude. From a mobile observatory at the Frauenberg near Marburg (Hesse) he measured the astronomical longitude difference between C.F. Gauß's observatory at Göttingen and F.G.B. Nicolai's observatory at Mannheim within an error of 0.̋4. To achieve this precision he first used a series of light signals for synchronizing the observatory clocks and, second, he very carefully corrected for the varying reaction time of the observers. By comparing these astronomical results with the geodetic-determined longitude differences he had recently measured for the triangulation of Kurhessen, he was able to extract a combined value of the deflection of the vertical in longitude of Göttingen and Mannheim. His results closely agree with modern vertical deflection data.

  6. FU Orionis Outbursts and the Solar Nebula

    1998-01-01

    Protostellar systems are variable on many timescales. The FU Orionis outburst is one of the most drastic forms of variability known to occur in low mass stellar systems. During a typical outburst lasting several decades, system luminosities may be a hundred times what is normal of the quiescent state. FU Orionis outburst events are believed to have significant impacts on the thermal structure of the protosolar nebula. Their existence has been utilized to explain features in the meteoritic record from thermally induced homogenization to chondrule formation. Recent numerical models have shown the viability of the hypothesis that the radiation observed during outburst is emitted by a luminous circumstellar disk transporting mass at a thousand times the quiescent rate. We will begin by describing what is known about the FU Orionis outburst phenomenon from recent observations and theory. We will discuss evidence that suggests that outburst radiation is emitted by a circumstellar disk rather than by the star and will briefly describe the thermal instability as a mechanism for outburst. Additional information is contained in the original extended abstract.

  7. Are Comet Outbursts the Result of Avalanches?

    NASA Astrophysics Data System (ADS)

    Steckloff, Jordan; Melosh, H. Jay

    2016-10-01

    Recently, Rosetta became the first spacecraft to make high-resolution observations of a comet outburst (a rapid, ephemeral increase in dust production) emerging from the surface of a comet nucleus. These outbursts occurred near perihelion, lasted only a few minutes, and produced a highly collimated outburst plume without any corresponding increase in H2O or CO2 gas production (See abstract by Rinaldi et al.). These observations cannot be explained by proposed driving outburst mechanisms (such as crystallization of amorphous ice, cryovolcanic gas exsolution, or explosive outgasing of subsurface chambers), all of which are driven by gas, and would therefore lead to an increase in the gas production.We propose instead that the observed outbursts on Comet 67P/Churyumov-Gerasimenko (hereafter 67P) are the result of cometary avalanches. The surface of 67P contains many cliffs and scarps, with dusty surface layers blanketing the shallower slopes above and below these steep surfaces. The Rosetta spacecraft returned clear evidence of mass wasting, which form icy talus fields that are the source of much of 67P's cometary activity. Additionally, Rosetta observed morphological changes over time in the shallower, dusty surface layers above these steep slopes, which suggest that avalanches periodically release dusty materials onto these active talus fields.Here we present the results of a numerical simulation of dusty material avalanching into an active area (active talus field). These simulations show that such avalanches will generate a transient, highly collimated outburst plume that closely matches the observed morphology of the outbursts emanating from the surface of 67P. This mechanism predicts that cometary outbursting should not be directly associated with any increase in gas production, consistent with observations. Additionally, we show that regions of the nucleus that have sourced outburst plumes contain steep surfaces (above the angle of repose), which is required

The scientific program was of excellent quality featuring 64 talks, including 41 from invited speakers. The Keynote Lecture, delivered by Chris Somerville (Energy Biosciences Institute/UC Berkeley) was particularly relevant to US agriculture and energy research and was titled The Development of Cellulosic Biofuels. There were also 6 community-organized workshops featuring 30 additional talks on topics including Frontiers in Plant Systems Biology, Sources and strategies for Gene Structure, Gene Function, and Metabolic Pathway annotation at TAIR and AraCyc, Advanced Bioinformatic Resources for Arabidopsis, Laser Microtechniques and Applications with Arabidopsis, Plant Proteomics- Tools, Approaches, Standards and Breakthroughs in Studying the Proteome, and Phytohormone Biosynthesis and Signal Transduction. Conference organizers arranged a special seminar by Jim Collins (head of the Directorate of Biosciences at NSF) to provide a community discussion forum regarding the future of Arabidopsis research. Approximately 575 posters were presented in topic areas including, among others, Development, Signal Transduction, Cell Walls, Non-Arabidopsis Systems, and Interactions with Biotic and Abiotic Factors. All conference abstracts and the full program are posted at The Arabidopsis Information Resource (TAIR), a publicly-accessibly website (www.arabidopsis.org/news/abstracts.jsp.) A survey completed by approximately 40% of the meeting attendees showed high satisfaction with the quality of the presentations, meeting organization and the city of Montreal.

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

    The Alice far-ultraviolet spectrograph on board the Rosetta spacecraft currently operating around the comet 67P/Churyumov-Gerasimenko experiences an anomalistic feature (AF) that has proven nearly constant at comet separations below 450 km.1 This feature varies rapidly on the second time scale and displays no relation to any measured parameters with the exception of comet separation. Simulations showed that nanograins and ions could create the feature through a range of possible masses, velocities, charges, and energies. This paper builds on research published in Reference 1 that explored the behaviors and morphology of the AF. Observations taken on February 19th, 2016 during a dust outburst observed by several other instruments (Eberhard Grun, in prep) verified that the most common morphology of the AF is linked to dust and charged nanograins.

    The following three publications which reference the above grant from the NASA Origins of Solar Systems program are attached and form the final technical report for this project. The research involved comparisons of the spectral energy distributions of FU Orionis objects with theoretical models and associated studies of the structure of the outbursting accretion disks, as well as related studies on the effects of magnetic fields in disks, which will lead in the future to models of FU Orionis outbursts which include the effects of magnetic fields. The project was renewed under a new grant NAGW-4456, entitled 'Effects of FU Orionis Outbursts on Protoplanetary Disks'. Work now being prepared for publication deals more specifically with the issue of the effects of the outbursts on protoplanetary formation. Models of the spectral energy distribution of FU Orionis stars. A simple model of a buoyant magnetic dynamo in accretion disks and a numerical study of magnetic buoyancy in an accretion disk have been submitted.

    1997-03-14

    Lack of a 19th-century baseline temperature against which 20th-century warming can be referenced constitutes a deficiency in understanding recent climate change. Combination of borehole temperature profiles, which contain a memory of surface temperature changes in previous centuries, with the meteorological archive of surface air temperatures can provide a 19th-century baseline temperature tied to the current observational record. A test case in Utah, where boreholes are interspersed with meteorological stations belonging to the Historical Climatological Network, yields a noise reduction in estimates of 20th-century warming and a baseline temperature that is 0.6° ± 0.1°C below the 1951 to 1970 mean temperature for the region.

    1995-01-01

    A nova outburst is the consequence of the accretion of hydrogen rich material onto a white dwarf and it can be considered as the largest hydrogen bomb in the Universe. The fuel is supplied by a secondary star in a close binary system while the strong degeneracy of the massive white dwarf acts to contain the gas during the early stages of the explosion. The containment allows the temperature in the nuclear burning region to exceed 10(sup 8)K under all circumstances. As a result a major fraction of CNO nuclei in the envelope are transformed into (beta)(sup +)-unstable nuclei. We discuss the effects of these nuclei on the evolution. Recent observational studies have shown that there are two compositional classes of novae; one which occurs on carbon-oxygen white dwarfs, and a second class that occurs on oxygen-neon-magnesium white dwarfs. In this review we will concentrate on the latter explosions since they produce the most interesting nucleosynthesis. We report both on the results of new observational determinations of nova abundances and, in addition, new hydrodynamic calculations that examine the consequences of the accretion process on 1.0M(sub (circle dot)), 1.25M(sub (circle dot)), and 1.35M(sub (circle dot)) white dwarfs. Our results show that novae can produce (sup 22)Na, (sup 26)Al, and other intermediate mass nuclei in interesting amounts. We will present the results of new calculations, done with updated nuclear reaction rates and opacities, which exhibit quantitative differences with respect to published work.

  13. Twentieth century sea level: An enigma

    Munk, Walter

    2002-01-01

    Changes in sea level (relative to the moving crust) are associated with changes in ocean volume (mostly thermal expansion) and in ocean mass (melting and continental storage): ζ(t) = ζsteric(t) + ζeustatic(t). Recent compilations of global ocean temperatures by Levitus and coworkers are in accord with coupled ocean/atmosphere modeling of greenhouse warming; they yield an increase in 20th century ocean heat content by 2 × 1023 J (compared to 0.1 × 1023 J of atmospheric storage), which corresponds to ζgreenhouse(2000) = 3 cm. The greenhouse-related rate is accelerating, with a present value ζ̇greenhouse(2000) ≈ 6 cm/century. Tide records going back to the 19th century show no measurable acceleration throughout the late 19th and first half of the 20th century; we take ζ̇historic = 18 cm/century. The Intergovernmental Panel on Climate Change attributes about 6 cm/century to melting and other eustatic processes, leaving a residual of 12 cm of 20th century rise to be accounted for.

  14. Twentieth century sea level: an enigma.

    Changes in sea level (relative to the moving crust) are associated with changes in ocean volume (mostly thermal expansion) and in ocean mass (melting and continental storage): zeta(t) = zeta(steric)(t) + zeta(eustatic)(t). Recent compilations of global ocean temperatures by Levitus and coworkers are in accord with coupled ocean/atmosphere modeling of greenhouse warming; they yield an increase in 20th century ocean heat content by 2 x 10(23) J (compared to 0.1 x 10(23) J of atmospheric storage), which corresponds to zeta(greenhouse)(2000) = 3 cm. The greenhouse-related rate is accelerating, with a present value zeta(greenhouse)(2000) approximately 6 cm/century. Tide records going back to the 19th century show no measurable acceleration throughout the late 19th and first half of the 20th century; we take zeta(historic) = 18 cm/century. The Intergovernmental Panel on Climate Change attributes about 6 cm/century to melting and other eustatic processes, leaving a residual of 12 cm of 20th century rise to be accounted for. The Levitus compilation has virtually foreclosed the attribution of the residual rise to ocean warming (notwithstanding our ignorance of the abyssal and Southern Oceans): the historic rise started too early, has too linear a trend, and is too large. Melting of polar ice sheets at the upper limit of the Intergovernmental Panel on Climate Change estimates could close the gap, but severe limits are imposed by the observed perturbations in Earth rotation.

    Most of the 19th- and early 20th-century physics texts in my collection have frontispieces: a telegraph system, the cross-section of a steam locomotive, colored lithographs of spectra, etc. One of my favorites is the wood-cut illustration of an apparatus collection that serves as the frontispiece to Hotze's 1897 physics textbook. In modern parlance, this is a conceptual text as it does not have a single equation.

    At the 19th conference of the European Haematology Association in Milan, we saw the true and dramatic changes brought about by the integration of extensive genomic information in clinical practice, and the dilemmas that accompany such a rapid increase in knowledge. Each disease is sliced more and more into smaller pieces, each with its own better-determined outcome and treatment. We also observed the rise of mutant-specific epigenetic agents, which benefit from knowing the underlying genetic abnormality to specifically assign an epigenetic drug where it is needed. In contrast to the 'one mutation, one drug' approach, others are pursuing the search for drugs targeting pathways fundamental for the survival of all or most cancer cells, sometimes looking at more 'exotic' pathways like neddylation or nuclear export.

    The outburst is announced of the recurrent nova U Sco at magnitude V=8.05 on 2010 January 28.4385 UT, according to observations by Barbara G. Harris, New Smyrna Beach, FL, USA. The outburst was confirmed by Shawn Dvorak, Clermont, FL, USA, who estimated it at V~8.8 at Jan 28.4743. Prior to outburst, U Scorpii was measured at V=18.2 on Jan 27.4501 (Harris), and estimated at m(vis) <16.5 on January 27.6271 (Mike Linnolt, Hoolehua, HI, USA). Observations in the AAVSO International Database show that the last outburst of U Sco occurred on 1999 February 25, when the star reached visual magnitude 7.5. U Sco is an extremely fast nova, and will reach maximum and decline by one magnitude within one day. Visual, CCD, and PEP observations are urgently requested, including unfiltered CCD time series. Please obtain S/N of at least 50 for all instrumental photometry. Observers are asked to use filters when performing single-measure photometry, but unfiltered time series is also requested beginning immediately and continuing for the next month. The AAVSO has been participating in a campaign on U Sco by request of Dr. Bradley Schaefer (LSU; see AAVSO Alert Notice 367). This nova outburst will be observed by several ground- and space-based observatories world-wide, and your observations are urgently requested to provide the overall, long-term optical light curve of U Sco. Finder charts with sequence may be created using the AAVSO Variable Star Plotter (http://www.aavso.org/vsp). Observations should be submitted to the AAVSO International Database.

    Modern historiography of collective attitudes, practices, and conflicts surrounding death often focuses on the institutional history of cemeteries and nonreligious funerals in 19th-century France. Institutional and cultural discussions concerning funerals and cemeteries also divided nineteenth-century Belgium. This article explores emblematic civil burials and the secularization of cemeteries in major Belgian cities. The article distinguishes different dimensions of the secularization of death and highlights the particular nature of Belgian funerary conflicts and burial reform within a broader European context.

  20. The intermediate polar GK Persei: An unstable relation of the X-ray and the optical intensities in a series of outbursts

    Context. GK Per is an intermediate polar that has been displaying dwarf nova outbursts since the middle of the twentieth century. Aims: I analyzed a series of such outbursts in the optical and X-ray bands. I pay attention to the relation of intensities of the optical and X-ray emissions, and its reproducibility in a series of these consecutive outbursts. Methods: This analysis uses the data from the BAT/Swift, ASM/RXTE, AAVSO, and AFOEV databases. It investigates the relation of the time evolution of the profiles of outbursts in the individual bands (hard X-ray, medium/hard X-ray, and optical). Results: This analysis shows that the X-ray intensity steeply rises only in the start of the optical outburst and steeply declines only when the optical outburst comes to its end. However, the 1.5-50 keV band intensity saturates and balances on a plateau during the outburst. (The longer the outburst, the longer its plateau.) The peak X-ray intensities of this series display a significantly narrower range than the optical ones (a factor of about two versus a factor of about eight). This implies a discrepancy between the mass flow through the disk and the production of the X-ray emission via bremsstrahlung at the polar caps of the white dwarf. This discrepancy is the largest in the time of the peak optical intensity when the whole disk (or at least its inner part) is in the hot state and the flow of matter through the disk is the greatest. This study shows that a series of outbursts constitutes more general properties of this discrepancy. I argue that the saturation of the X-ray luminosity in outburst cannot be caused by a dominant increase in X-ray absorption. In the interpretation, large structural changes of the accreting regions at the magnetic poles of the white dwarf occur during the outburst. A buried shock proposed by some authors for polars is also promising for explaining the X-ray light curves of outbursts of GK Per. This research made use of the BAT/Swift, ASM

    encounters with this giant planet. For instance, it passed Jupiter at a distance of about 30 million kilometers in 1882 and 1894, and again at 40 million kilometres in 1965. SW-3 belongs to the so-called ``Jupiter family'' of comets. Some time ago, SW-3 was chosen as a back-up target for the upcoming Rosetta space mission by the European Space Agency (ESA) because the elliptical orbit of this particular comet may be reached with a relatively small expenditure of rocket fuel (the prime target is Comet Wirtanen). That allows to carry more scientific instruments on this extraordinary mission which aims at a long-term study of a cometary nucleus from a spacecraft in circum-cometary orbit. Rosetta will be launched early in the next century and will also carry two landing modules which will descend on the surface of the nucleus. The Dramatic Outburst of SW-3 In order to study this potential Rosetta target comet, Hermann Boehnhardt (Astronomical Institute of the Ludwig Maximilian University, Munich, Germany) and Hans-Ulrich Kaufl (ESO-Garching) early in 1995 applied for simultaneous observing time at the ESO 3.6-m telescope and 3.5-m New Technology Telescope (NTT) at the La Silla Observatory. In May 1995, the ESO Observing Programmes Committee (OPC) granted the astronomers some nights for these observations in mid-December 1995 with the TIMMI and EMMI instruments at the 3.6-m and the NTT, respectively, i.e. not quite two months after the predicted perihelion passage on September 22, when the comet would be closest to the Sun (140 million kilometres). Meanwhile, SW-3 was moving closer towards the Sun. After its recovery in December 1994 with the 3.5-metre reflector at the Calar Alto Observatory in Spain, Kurt Birkle and Hermann Boehnhardt collected a series of almost monthly images with that telescope until late June 1995, showing that the comet developed normally with respect to its brightness and the coma and tail. On August 20, it was observed by a Japanese amateur astronomer at

    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.

    1987-01-01

    To evaluate the heritability of a personality trait, "having temper outbursts," and of associated diagnoses, we obtained histories of first degree relatives on two groups: (1) patients with temper outbursts (N = 33), and (2) diverse psychiatric patients without temper outbursts (N = 12). Family interviews were conducted blind to patient (temper or not) status, using a modified version of the Family History RDC. Though Ns are relatively small, and results therefore require confirmation, the data indicate familial transmission of temper problems; an average of 18.2% of Group 1 relatives had temper problems, compared to 4.3% for Group 2. The trait of having temper outbursts was more strongly transmitted than were specific diagnoses (e.g. Intermittent Explosive Disorder, Antisocial Personality Disorder or Residual Attention Deficit Disorder) associated with temper outbursts. Patients with neurological conditions apparently related to their temper outbursts were less likely to have positive family histories.

    The unprecedented extent of coverage provided by Kepler observations recently revealed outbursts in two hydrogen-atmosphere pulsating white dwarfs (DAVs) that cause hours-long increases in the overall mean flux of up to 14%. We have identified two new outbursting pulsating white dwarfs in K2, bringing the total number of known outbursting white dwarfs to four. EPIC 211629697, with {T}{eff} = 10,780 ± 140 K and {log} g = 7.94 ± 0.08, shows outbursts recurring on average every 5.0 days, increasing the overall flux by up to 15%. EPIC 229227292, with {T}{eff} = 11,190 ± 170 K and {log} g = 8.02 ± 0.05, has outbursts that recur roughly every 2.4 days with amplitudes up to 9%. We establish that only the coolest pulsating white dwarfs within a small temperature range near the cool, red edge of the DAV instability strip exhibit these outbursts.

    We extend the one-dimensional, two-zone models of long-term protostellar disk evolution with infall of Zhu et al. to consider the potential effects of a finite viscosity in regions where the ionization is too low for the magnetorotational instability (MRI) to operate (the {sup d}ead zone{sup )}. We find that the presence of a small but finite dead zone viscosity, as suggested by simulations of stratified disks with MRI-active outer layers, can trigger inside-out bursts of accretion, starting at or near the inner edge of the disk, instead of the previously found outside-in bursts with zero dead zone viscosity, which originate at a few AU in radius. These inside-out bursts of accretion bear a qualitative resemblance to the outburst behavior of one FU Ori object, V1515 Cyg, in contrast to the outside-in burst models, which more closely resemble the accretion events in FU Ori and V1057 Cyg. Our results suggest that the type and frequency of outbursts are potentially a probe of transport efficiency in the dead zone. Simulations must treat the inner disk regions, R {approx}< 0.5 AU, to show the detailed time evolution of accretion outbursts in general and to observe the inside-out bursts in particular.

    Summary This lecture is not a historical lecture, but rather a journey through the “story” of neurology in Italy from its “prehistoric” beginning in the 19th century. The birth of a neurological school is that magical moment in which a founder attracts disciples: the more capable this founder is of transmitting methodology and allowing his pupils intellectual freedom, the longer his memory will live on. On the basis of this idea, the scientific biography of a few leading Italian neurologists of the 20th century is outlined, starting from Leonardo Bianchi, founder of the Italian Neurological Society in 1907.

    EXORs are extreme T Tauri stars that experience major UV-optical eruptions (3-5 mag) that last about a year. These recurring outbursts driven by high accretion rates assist in dispersal of the circumstellar disk and the large X-ray-UV flux injected into the local environment modifies the physical and chemical history, influencing planet formation and time scales. Little X-ray data exists on these stars during either quiescent or outburst phases, so basic details such as how much X-ray flux is produced during eruption is unknown. We will characterize the X-ray properties of 7 EXORs in their quiescent phase. TOO time is requested to obtain high-quality spectra if an eruption occurs during AO5. Contrasting quiescent and outburst properties provides crucial insight into the physics.

    Pre-outburst and post-outburst light curves and post-outburst eclipse timings are analyzed to measure any period (P) change related to nova CI Aql's outburst of early 2000 and a mean post-outburst dP/dt, which then lead to estimates of the accreting component's rate of mass (M) change and its overall outburst-related change of mass over roughly a decade of observations. We apply a recently developed procedure for unified analysis of three timing-related data types (light curves, radial velocities, and eclipse timings), although with only light curves and timings in this case. Fits to the data are reasonably good without need for a disk in the light-curve model, although the disk certainly exists and has an important role in our post-outburst mass flow computations. Initial experiments showed that, although there seems to be an accretion hot spot, it has essentially no effect on derived outburst-related ΔP or on post-outburst dP/dt. Use of atomic time (HJED) in place of HJD also has essentially nil effect on ΔP and dP/dt. We find ΔP consistently negative in various types of solutions, although at best only marginally significant statistically in any one experiment. Pre-outburst HJD {sub 0} and P results are given, as are post-outburst HJD {sub 0}, P, and dP/dt, with light curves and eclipse times as joint input, and also with only eclipse time input. Post-outburst dP/dt is negative at about 2.4σ. Explicit formulae for mass transfer rates and epoch-to-epoch mass change are developed and applied. A known offset in the magnitude zero point for 1991-1994 is corrected.

  17. Glacier lake outburst floods - modelling process chains

    NASA Astrophysics Data System (ADS)

    Schaub, Yvonne; Huggel, Christian; Haeberli, Wilfried

    2013-04-01

    New lakes are forming in high-mountain areas all over the world due to glacier recession. Often they will be located below steep, destabilized flanks and are therefore exposed to impacts from rock-/ice-avalanches. Several events worldwide are known, where an outburst flood has been triggered by such an impact. In regions such as in the European Alps or in the Cordillera Blanca in Peru, where valley bottoms are densely populated, these far-travelling, high-magnitude events can result in major disasters. For appropriate integral risk management it is crucial to gain knowledge on how the processes (rock-/ice-avalanches - impact waves in lake - impact on dam - outburst flood) interact and how the hazard potential related to corresponding process chains can be assessed. Research in natural hazards so far has mainly concentrated on describing, understanding, modeling or assessing single hazardous processes. Some of the above mentioned individual processes are quite well understood in their physical behavior and some of the process interfaces have also been investigated in detail. Multi-hazard assessments of the entire process chain, however, have only recently become subjects of investigations. Our study aims at closing this gap and providing suggestions on how to assess the hazard potential of the entire process chain in order to generate hazard maps and support risk assessments. We analyzed different types of models (empirical, analytical, physically based) for each process regarding their suitability for application in hazard assessments of the entire process chain based on literature. Results show that for rock-/ice-avalanches, dam breach and outburst floods, only numerical, physically based models are able to provide the required information, whereas the impact wave can be estimated by means of physically based or empirical assessments. We demonstrate how the findings could be applied with the help of a case study of a recent glacier lake outburst event at Laguna

It seems that after the end of the symbiotic nova phase, AG Peg became a member of the classical symbiotic stars group.
