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

Time and Time Again; Determination of longitude at sea in the 17th Century

de Grijs, Richard

2017-11-01

Determination of one's longitude at sea has perplexed sailors for many centuries. The significant uptake of world trade in the 17th and 18th Centuries rendered the increasingly urgent need to solve the 'longitude problem', an issue of strategic national importance. Historical accounts of these efforts often focus almost exclusively on John Harrison's role in 18th-Century Britain. This book starts instead from Galileo Galilei's late-16th-Century development of an accurate pendulum clock, which was first achieved in practice in the mid-17th-Century by Christiaan Huygens in the Dutch Republic. It is primarily based on collections of letters that have not been combined into a single volume before. Extensive introductory chapters on the history of map making, the establishment of the world's reference meridian at Greenwich Observatory, and the rise of the scientific enterprise provide the appropriate context for non-expert readers to fully engage with the book's main subject matter.

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

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

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

NASA Astrophysics Data System (ADS)

Lequeux, James

2014-07-01

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

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

2003-12-01

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

Clear cutting (10-13th century) and deep stable economy (18-19th century) as responsible interventions for sand drifting and plaggic deposition in cultural landscapes on aeolian sands (SE-Netherlands).

The landscape in extensive areas in SE-Netherlands is underlain by coversand, deposited during the Late Glacial of the Weichselian. In the Preboreal, aeolian processes reduced soil formation. From the Preboreal to the Atlantic a deciduous climax forest developed. The geomorphology was a coversand landscape, composed of ridges (umbric podzols), coversand plains (gleyic podzols), coversand depressions (histic podzols) and small valleys (gleysols). The area was used by hunting people during the Late Paleolithic and Mesolithic. During the Bronze and Iron Ages the area was populated by people, living from forest grazing, shifting cultivation and trade. The natural deciduous forest gradually degraded into Calluna heath. The deforestation accelerated the soil acidification and affected the hydrology, which is reflected in drying out of ridges and wetting of depressions, promoting the development of histic podzols and even histosols. Aeolian erosion was during this period restricted to local, small scale sand drifting, related to natural hazards as forest fires and hurricanes and shifting cultivation. Sustainable crop productivity on chemically poor sandy substrates required application of organic fertilizers, composed of a mixture of organic litter and animal manure with a very low mineral compound, produced in shallow stables. At least since 1000 AD, heath management was regulated by a series of rules that aimed to protect the valuable heat lands against degradation. During the 11th, 12th and 13th centuries there was an increasing demand for wood and clear cutting transformed the majority of the forests in driftsand landscapes. The most important market was formed by the very wealthy Flemish cities. The exposed soil surface was subjected to wind erosion and sand drifting which endangered the Calluna heath, arable land and even farmhouses. As a consequence, umbric podzols, the natural climax soil under deciduous forests on coversand, degraded into larger scale driftsand

[Effects of the periodical spread of rinderpest on famine, epidemic, and tiger disasters in the late 17th Century].

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

Also the unique of them, which is still in use, the New Rectified Julian calendar of the Orthodox Church, adopted according to proposition of Milutin Milanković on the Congress of Orthodox Churches in 1923 in Constantinople, is presented and discussed. At the end, difficulties to introduce a new calendar are discussed as well.

Did some 18th and 19th century treatments for mental disorders act on the brain?

Leonard, Edward C

2004-01-01

Review of 18th and 19th century psychiatric therapies raises the possibility that several may have altered the activity of vasopressin or Na-K-ATPase. Bleeding, whirling, nausea created by medicines, and vagus nerve stimulation by application of electricity through the skin all perturb the hypothalamic hormone, arginine vasopressin, while helleborus and digitalis inhibit the sodium pump enzyme, Na-K-ATPase. These approaches were used with reported benefit many years ago, acting on the brain in ways ongoing research suggests may play a role in affective disorders. Study of long-abandoned treatments may clarify their mechanisms of action and the characteristics of responsive patients.

The 8th Century Megadrought Across North America

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

14th-16th century Danube floods and long-term water-level changes reflected in archaeological-sedimentary evidence - in comparison with documentary evidence

Kiss, Andrea; Laszlovszky, József

2014-05-01

In the present paper an overview of published and unpublished results of archaeological and sedimentary investigations, predominantly reflect on 14th-16th-century changes, are provided and compared to documentary information on flood events and long-term changes. Long-term changes in flood behaviour and average water-level conditions had long-term detectable impacts on sedimentation and fluvio-morphological processes. Moreover, the available archaeological evidence might also provide information on the reaction of the society, in the form of changes in settlement organisation, building structures and processes. At present, information is mainly available concerning the 16th, and partly to the 14th-15th centuries. Medium and short term evidence mainly corresponds to the main flood peaks or even to single catastrophic flood events. Such processes may be identified in archaeological evidence concerning the second half of the 14th, early 15th centuries; while most of the cases listed above were connected to the flood peak (and/or generally increasing water-level conditions) of the late 15th and early 16th centuries. In other cases connections between sedimentary/archaeological evidence and the mid- and late 16th-century high flood-frequency period were presumed. Documentary evidence referring to the same period suggests that higher flood frequency and intensity periods occurred in the early and mid 16th century; a probably more prolonged flood rich period took place in the second half of the 16th century, with a peak in the late 1560s-early 1570s and maybe with another at the end of the 16th century. Earlier flood peaks in documentary evidence were detected on the Danube at the turn of the 14th-15th centuries and in the last decades of the 15th century, continuing in the early 16th century.

Four candles. Original perspectives and insights into 18th century hospital child healthcare

PubMed Central

Williams, A N

2007-01-01

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

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

Kiss, Andrea

2017-04-01

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

The role of political and welfare state characteristics in infant mortality: a comparative study in wealthy countries since the late 19th century.

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

Human impacts of hydrometeorological extremes in the Bohemian-Moravian Highlands derived from documentary sources in the 18th-19th centuries

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

Regina Salomea Rusiecki (later Pilsztynowa) was a young, poorly educated Polish Catholic woman in the 18th century who became well known in Eastern Europe and the Ottoman Empire because of her skill in the treatment of cataracts and some other medical problems. She was born in 1718, and at the age of 14 she married an experienced, but significantly older, German Lutheran physician and ophthalmologist, Jakob Halpir. By helping him eagerly in his work, Pilsztynowa learned a great deal of her husband's way of treating cataracts and other ailments, and she ambitiously made use of the friendship and help of other physicians whom she met on her travels. Although there are some occurrences that could lead one to question aspects of Pilsztynowa's straight and honest character, one has also to point to her readiness to help where she could.

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

Contemporary sources reveal little information about the social conditions of Jewish medical practitioners in 14th and 15th century Munich. Due to the concurrence on the local "medical market" none of the five Jewish doctors named in the documents could practice for a longer period in teh late medieval city. Unlike their co-religionists in several cities of Westphalia, where physicians and surgeons were lacking, no Jewish medical practitioner was ever employed by the Magistrate of Munich. Thus, all of them seemed to have hoped for an employment at the court of the Bavarian Dukes. But with the exception of Jacob of Landshut, physician to the Bavarian Dukes Steven III. and Albrecht III. during the second half of the 14th century, whose medical career and social environment can roughly be retraced, no Jewish doctor seems to have been in service of the court for a longer time.

Passionate men, emotional women: psychology constructs gender difference in the late 19th century.

PubMed

Shields, Stephanie A

2007-05-01

The author examines British and American scientific psychology's portrayal of natural and ideal masculinity and femininity in the late 19th century to show how purported differences in emotion and reason were critical to explaining the evolutionary foundation of existing social hierarchies. Strong emotion was identified with heterosexual manliness and men's purportedly better capacity to harness the power of emotion in the service of reason. "Feminine" emotion was portrayed as a comparatively ineffectual emotionality, a by-product of female reproductive physiology and evolutionary need to be attractive to men. The author argues that constructions of emotion by psychology served an important power maintenance function. A concluding section addresses the relevance of this history to the politics of emotion in everyday life, especially assertions of emotional legitimacy.

[The creation of hospitals by charities in Minas Gerais (Brazil) from 18th to 20th century].

PubMed

Marques, Rita de Cássia

2011-01-01

This article is the fruit of research into the cultural heritage of healthcare in Minas Gerais (Brazil) and explores the construction of hospitals supported by Catholic charities from the 18th to 20th century. Catholicism has always been strong in Minas Gerais, partly because the Portuguese Crown prohibited the free travel of priests, who were suspected of illegally trading in gold from the mines. A brotherhood was responsible for creating the first Santa Casa, in Vila Rica. Another very important religious group in Brazil, the Vincentians, was also devoted to charitable works and propagated the ideas on charity of Frederico Ozanan, based on the work of St. Vincent de Paul. This group comprised both a lay movement, supported by conferences organized by the St. Vincent de Paul Society, and a religious order, the Vincentian priests and nuns. Catholic physicians make up the third group studied here, organized in a professional association promoted by the Catholic Church. The brotherhoods, Vincentians, and associations, with their Santa Casas, represent a movement that is recognized worldwide. The enormous Catholic participation in these charitable works brought in the physicians, who would often make no charge and exerted efforts to create hospitals that served the population. Although the capital of Minas Gerais was the creation of republicans and positivists in the 20th century, with their ideas of modernity, it remained dependent on Christian charity for the treatment of the poor.

Georg Philip Nenter and medicine "by notes" in the 18th century.

Even though it is true that the medical historiography of the 18th century is lacking in great scientific personalities, it is equally true that the entire century is characterized by continuous efforts to encapsulate the medical area of knowledge, acquired until then, in precise and systematic outlines, to serve the academic teaching of the subject of medicine. Georg Philip Nenter, a pupil of Georg Ernst Stahl and a professor of medicine in the University of Strasburg, could not help being influenced by that atmosphere. He added though, in our opinion, a touch of remarkable modernity. In fact his volume Fundamenta medicinae teoretico-pratica (Venice, 1735) is a wonderful collection of the notes taken during his lectures. The description of various diseases - renal diseases in particular - maintains a very systematic development of the subject through various chapters (definition, clinical manifestations, differential diagnosis, prognosis, treatment and examples of specific prescriptions), as if students were being addressed.

George Beard and Lydia Pinkham: gender, class, and nerves in late 19th century America.

Davis, D L

1989-01-01

A historical comparison of the careers of George Beard, medical doctor, and Lydia Pinkham, feminist and patent medicine maker, demonstrates the complex social nature of the experience of nerves among late 19th century women. Special attention is paid to the roles played by changing gender and class ideologies in Pinkham's and Beard's theories of nerves during the period from the 1870s to World War I. A comparison of contemporary anthropological and historical studies of gender and nerves leads to the conclusion that nerves, as a female complaint, takes hold of the popular and medical imagination during periods of dramatic social change which threaten women's traditional family roles and challenge their sense of self-identity.

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

Weston, Robert

2012-01-01

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

Venetian Rule and Control of Plague Epidemics on the Ionian Islands during 17th and 18th Centuries

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

Nonsystematic review of the Madrid newspaper Gaceta de Madrid y Diario curioso, erudito, económico y comercial (Madrid Gazette, curious, erudite, financial and commercial) between 1759 and 1790. Review of the medical literature of the 18th century preserved in the Fondo Antiguo of the Biblioteca Histórica of Universidad Complutense de Madrid (Historical Resource of the Historical Library of the Complutense University of Madrid). A Google search of «Charles Richard de Beauregard». Charles de Beauregard focused his professional work mainly on the treatment of the urethral sequela of blennorrhagia, phimosis and paraphimosis. He introduced to 18th century Spanish society (with purported originality and clear commercial interests) therapeutic methods based on lead acetate that had already been developed in France by Thomas Goulard. The urethral sequela of diseases such as blennorrhagic urethritis, stenotic phimosis and paraphimosis were highly prevalent in 18th century Madrid and required complex solutions for the practice of urology of that era. Charles de Beauregard introduced innovative but not original treatments that were invasive but not bloody and that provided him with fame and social prestige. He advertised his professional activity and marketed his therapeutic products through advertisements submitted to the daily press (Madrid Gazette, Gaceta de Madrid). Copyright © 2015 AEU.

Floods of the Maros river in the early modern and modern period (16th-20th centuries)

2016-04-01

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

Flood hazard and a rapidly growing capital in the floodplain: Social response on major 18th-century Danube floods in Pest (East-Budapest)

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

As early as 1783, the almost forgotten philosopher, metaphysicist, and psychologist Ferdinand Ueberwasser (1752-1812) designated himself "Professor für empirische Psychologie und Logik" (professor of empirical psychology and logic) at the University of Münster, Germany. His position was initiated and supported by the minister and educational reformer Franz von Fürstenberg (1729-1810), who considered psychology a core scientific discipline that should be taught at each school and university. At the end of the 18th century, then, psychology seems to have been on the verge of becoming an independent academic discipline, about 100 years before Wilhelm Wundt founded the discipline's first official laboratory. It seems surprising that Ueberwasser's writings-including a seminal textbook on empirical psychology-have been almost entirely overlooked in most historical accounts. We focus on this important founding moment of psychological science and on the circumstances that eventually brought this seminal development to a halt. © The Author(s) 2016.

Crespi d'Adda is a late 19th century company town established around a textile factory by Cristoforo Benigno Crespi and his son Silvio. It was an ideal model of company residency being a self-sufficient microcosm equipped with all the services needed by a community where the life of workers and their families was revolving around the factory and the working requirements. It was the expression of philanthropic and patronizing enlightened entrepreneurs at that time, committed in protecting workers' life inside and outside the factory, resulting into a more affectionate and productive manpower. Silvio Benigno Crespi developed an extensive activity to improve working conditions, with special reference to accident prevention and work-related diseases, as well as night work in factories, weekly day off, reduction of working hours: we can say that in some ways he was concerned also with psychosocial risks.

20th century climate warming and tree-limit rise in the southern Scandes of Sweden.

PubMed

Kullman, L

2001-03-01

Climate warming by ca. 0.8 degree C between the late-19th and late-20th century, although with some fluctuations, has forced multispecies elevational tree-limit advance by > 100 m for the principal tree species in the Swedish part of the Scandinavian mountain range. Predominantly, these processes imply growth in height of old-established individuals and less frequently upslope migration of new individuals. After a slight retardation during some cooler decades after 1940, a new active phase of tree-limit advance has occurred with a series of exceptionally mild winters and some warm summers during the 1990s. The magnitude of total 20th century tree-limit rise varies with topoclimate and is mainly confined to wind-sheltered and snow-rich segments of the landscape. Thickening of birch tree stands in the "advance belt" has profoundly altered the general character of the subalpine/low alpine landscape and provides a positive feedback loop for further progressive change and resilience to short-term cooling episodes. All upslope tree-limit shifts and associated landscape transformations during the 20th century have occurred without appreciable time lags, which constitutes knowledge fundamental to the generation of realistic models concerning vegetation responses to potential future warming. The new and elevated pine tree-limit may be the highest during the past 4000 14C years. Thus, it is tentatively inferred that the 20th century climate is unusually warm in a late-Holocene perspective.

The definition of ileus has undergone deep changes over the last three millennia. The term ileus was originally used in Classic Greece to describe a common cause of intestinal obstruction, and subsequently the Romans would often translate it into the Latin word volvulus. During the Renaissance, ileus, volvulus and intussusception became synonymous with a vulgar term--Miserere Mei or Miserere colic--whose origin and evolution are still much of a mystery. This paper provides some historical investigation on the Miserere Mei or Miserere colic, with the aim of discussing its evolution within medical literature during the 17th and 18th centuries.

Lamy, Jérôme; Soulu, Frédéric

2015-01-01

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

Empiric physiology in epidemiologic doctrines of the 18th century, Hungarian General Norm of Health in 1770.

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

Sakai, Tatsuo

2015-09-01

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

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

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

PubMed

Müller, Irmgard; Fangerau, Heiner

2010-01-01

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.

Possible impacts of early-11th-, middle-12th-, and late-13th-century droughts on western Native Americans and the Mississippian Cahokians

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

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

Vaccines: the fourth century.

2009-12-01

Vaccine development, which began with Edward Jenner's observations in the late 18th century, has entered its 4th century. From its beginnings, with the use of whole organisms that had been weakened or inactivated, to the modern-day use of genetic engineering, it has taken advantage of the tools discovered in other branches of microbiology. Numerous successful vaccines are in use, but the list of diseases for which vaccines do not exist is long. However, the multiplicity of strategies now available, discussed in this article, portends even more successful development of vaccines.

Composition of 12-18 th century window glass in Belgium: Non-figurative windows in secular buildings and stained-glass windows in religious buildings

2007-07-01

A set of ca. 500 window glass fragments originating from different historical sites in Belgium and covering the period 12 th-18 th century was analyzed by means of electron probe microanalysis. Most samples are archaeological finds deriving from non-figurative windows in secular buildings. However, the analyzed set also contains glass sampled from still existing non-figurative windows in secular buildings and stained-glass windows in religious buildings. A sudden compositional change at the end of the 14 th century can be noticed among the series of glass compositions that were obtained. These changes could be related to the use of different glassmaker recipes and to the introduction of new raw materials for glass making.

Electrical treatment of spinal cord injuries in the 18th and 19th centuries.

Silver, John R; Weiner, M-F

2013-05-01

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.

Cholera is an acute infectious disease with high mortality if left untreated. Historically, between the 19(th) and 20(th) 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 18(th) 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 19(th) 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 19(th) and 20(th) centuries.

Émilie Du Châtelet's interpretation of the laws of motion in the light of 18th century mechanics.

PubMed

Reichenberger, Andrea

2018-06-01

Émilie Du Châtelet is well known for her French translation of Newton's Philosophiae Naturalis Principia Mathematica. It is the first and only French translation of Newton's magnum opus. The complete work appeared in 1759 under the title Principes mathématiques de la philosophie naturelle, par feue Madame la Marquise Du Chastellet. Before translating Newton's Principia, Du Châtelet worked on her Institutions de physique. In this book she defended the Leibnizian concept of living forces - vis viva. This paper argues that both of these works were part of a critical transformation and consolidation of post-Newtonian mechanics in the early 18th century, beyond Newton and Leibniz. This will be shown by comparing Du Châtelet's translation of Newton's axioms with her own formulations of the laws of motion in light of Thomas Le Seur's and François Jacquier's Geneva edition which holds a special place among the several editions of the Principia that appeared in the early 18th century.

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

USGS Publications Warehouse

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

2013-01-01

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

Skeletal and dental indicators of health in the late mediaeval (12-15th century) population from Nin, southern Croatia.

Novak, M; Martinčić, O; Strinović, D; Slaus, M

2012-12-01

A comprehensive bioarchaeological study of the late mediaeval (12-15th century) skeletal sample from Nin was carried out in order to test the historically documented hypothesis that during the late mediaeval period Nin sustained a period of rapid development that resulted in it becoming one of the major urban centres on the eastern Adriatic coast. The analysed pathological changes (alveolar bone disease, dental caries, dental enamel hypoplasia, cribra orbitalia, periostitis, tuberculosis, Schmorl's nodes, vertebral osteoarthritis, and bone fractures) indicate a relatively good quality of life for the majority of the population from this late mediaeval site. A low prevalence of dental pathologies suggests an adequate diet while a low frequency of long bone trauma testifies to a relatively peaceful life for the inhabitants of mediaeval Nin. Increased urban development during this period resulted in a worsening of sanitary conditions most likely caused by overcrowding, which is reflected in the presence of tuberculosis and the relatively high frequencies of dental enamel hypoplasia and cribra orbitalia. An additional health concern for the late mediaeval inhabitants of Nin may have been the presence of malaria, as recorded in numerous historical sources. Comparison with other Croatian mediaeval skeletal samples suggests that the inhabitants of late mediaeval Nin experienced somewhat better living conditions than their contemporaries from other parts of Croatia.

Lack of cool, not warm, extremes distinguishes late 20th Century climate in 979-year Tasmanian summer temperature reconstruction

Very few annually resolved millennial-length temperature reconstructions exist for the Southern Hemisphere. Here we present four 979-year reconstructions for southeastern Australia for the austral summer months of December-February. Two of the reconstructions are based on the Australian Water Availability Project dataset and two on the Berkeley Earth Surface Temperature dataset. For each climate data set, one reconstruction is based solely on Lagarostrobos franklinii (restricted reconstructions) while the other is based on multiple Tasmanian conifer species (unrestricted reconstructions). Each reconstruction calibrates ~50-60% of the variance in the temperature datasets depending on the number of tree-ring records available for the reconstruction. We found little difference in the temporal variability of the reconstructions, although extremes are amplified in the restricted reconstructions relative to the unrestricted reconstructions. The reconstructions highlight the occurrence of numerous individual years, especially in the 15th-17th Centuries, for which temperatures were comparable with those of the late 20th Century. The 1950-1999 period, however, stands out as the warmest 50-year period on average for the past 979 years, with a sustained shift away from relatively low mean temperatures, the length of which is unique in the 979-year record. The reconstructions are strongly and positively related to temperatures across the southeast of the Australian continent, negatively related to temperatures in the north and northeast of the continent, and uncorrelated with temperatures in the west. The lack of a strong relationship with temperatures across the continent highlights the necessity of a sub-regional focus for Australasian temperature reconstructions.

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

Changes in mercury and cadmium concentrations and the feeding behaviour of beluga (Delphinapterus leucas) near Somerset Island, Canada, during the 20th century.

Beluga (Delphinapterus leucas) continues to be an important food species for Arctic communities, despite concerns about its high mercury (Hg) content. We investigated whether Hg and cadmium (Cd) concentrations had changed during the 20th century in beluga near Somerset Island in the central Canadian Arctic, using well-preserved teeth collected from historical sites (dating to the late 19th century and 1926-1947) and during subsistence hunts in the late 1990s. Mercury concentrations in both historical and modern teeth were correlated with animal age, but 1990s beluga exhibited a significantly more rapid accumulation with age than late 19th century animals, indicating that Hg concentrations or bioavailability in their food chain had increased during the last century. The geometric mean tooth Hg concentration in modern 30 year old animals was 7.7 times higher than in the late 19th century, which corresponds to threefold higher concentrations in muktuk and muscle. Teeth from 1926 to 1947 were similar in Hg content to the late 19th century, suggesting that the increase had occurred sometime after the 1940s. In contrast, tooth Cd was not correlated with animal age and decreased during the last 100 years, indicating that anthropogenic Cd was negligible in this population. Late 19th century beluga displayed a greater range of prey selection (tooth delta15N values: 15.6-20.5 per thousand) than modern animals (delta15N: 17.2-21.1 per thousand). To prevent this difference from confounding the temporal Hg comparison, the Hg-age relationships discussed above were based on historical animals, which overlapped isotopically with the modern group. Tooth delta13C also changed to isotopically more depleted values in modern animals, with the most likely explanation being a significant shift to more pelagic-based feeding. Industrial Hg pollution is a plausible explanation for the recent Hg increase. However, without further investigation of the relationship between the range

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

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

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

Thunderstorm and cloud activities sometimes show a 27-day period, and this has long been studied to uncover a possible important link to solar rotation. Because the 27-day variations in the solar forcing parameters such as solar ultraviolet and galactic cosmic rays become more prominent when the solar activity is high, it is expected that the signal of the 27-day period in meteorological phenomena may wax and wane according to the changes in the solar activity level. In this study, we examine in detail the intensity variations in the signal of the 27-day solar rotational period in thunder and lightning activity from the 18th to the 19th centuries based on 150-year-long records found in old diaries kept in Japan and discuss their relation with the solar activity levels. Such long records enable us to examine the signals of solar rotation at both high and low solar activity levels. We found that the signal of the solar rotational period in the thunder and lightning activity increases as the solar activity increases. In this study, we also discuss the possibility of the impact of the long-term climatological conditions on the signals of the 27-day period in thunder/lightning activities.

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.

Observed and modeled patterns of lower stratospheric seasonal trends in Antarctic ozone and temperature in the late 20th (1979-2000) and the early 21st (2000-2014) centuries are compared. Patterns of pre-2000 observed Antarctic ozone decreases and stratospheric cooling as a function of month and pressure are followed by opposite-signed (i.e., "mirrored") patterns of ozone increases and warming post-2000. An interactive chemistry-climate model forced by changes in anthropogenic ozone depleting substances produces broadly similar mirrored features. Statistical analysis of unforced model simulations (from long-term model control simulations of a few centuries up to 1000 years) suggests that internal and solar natural variability alone is unable to account for the pattern of observed ozone trend mirroring, implying that forcing is the dominant driver of this behavior. Radiative calculations indicate that ozone increases have contributed to Antarctic warming of the lower stratosphere over 2000-2014, but dynamical changes that are likely due to internal variability over this relatively short period also appear to be important. Overall, the results support the recent finding that the healing of the Antarctic ozone hole is underway and that coupling between dynamics, chemistry, and radiation is important for a full understanding of the causes of observed stratospheric temperature and ozone changes.

An Eight-Century High-Resolution Paleoclimate Record From the Cariaco Basin: Baseline Variability and the 20th Century

The Cariaco Basin, Venezuela is well-positioned to record a detailed history of surface ocean changes along the southern margin of the Caribbean and the tropical Atlantic. Varved, high deposition rate sediments deposited under anoxic conditions and an abundance of well-preserved microfossils result in one of the few marine records capable of preserving evidence of interannual- to decadal-scale climate variability in the tropical Atlantic. Here we present Mg/Ca and stable oxygen isotope data with sub-decadal resolution derived from sediments deposited over the last 800 years. Mg/Ca measured on the planktic foraminifer Globigerina bulloides from a Cariaco Basin sediment core strongly correlates with spring (March-May) instrumental SSTs between AD 1870 and 1990. The long-term record displays a surprising amount of variability for a tropical location. The temperature swings are not necessarily related to local upwelling variability, but instead represent wider conditions in the Caribbean and western tropical Atlantic. The Mg/Ca-SST record also captures the decadal and multidecadal variability observed in global land and sea surface temperature anomalies, and correlates with Atlantic tropical storm and hurricane frequency over the late-19th and 20th centuries. On average, 20th century temperatures are not the warmest in the entire record, but they do show the largest increase in magnitude and fastest rate of SST change over the last eight hundred years. Stable oxygen isotope data also correlate well with instrumental SSTs, but not over the full instrumental record. Poor correlations with early instrumental SST data suggest a salinity overprint. However, reconstructing δ- water variability using combined Mg/Ca and δ18O data is not straightforward as the δ- water/salinity relationship varies seasonally in the Cariaco Basin. Comparisons with percent titanium data suggest intervals of both local and regional surface salinity changes over the length of the record.

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

NASA Astrophysics Data System (ADS)

Kiss, Andrea; Parajka, Juraj

2013-04-01

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

During this period the movement toward centralization in urban public schools gained considerable momentum. Educational historians have largely ignored the role school superintendents played in the…

Changing climatic and anthropogenic influences on the Bermejo wetland, through archival documents - Mendoza, Argentina, 16th-20th centuries

NASA Astrophysics Data System (ADS)

Prieto, M. R.; Rojas, F.

The wrong management of watering in the highest zones of the Mendoza northern oasis, the topography of the terrain and the deficient drainage, together with neotectonics phenomena, but mostly a dramatic and progressive increase of the Rio Mendoza flow volume originated the expansion of the wetlands area at the NE of the city of Mendoza at the turn of the 18th century, while in previous centuries it had retracted to a minimum. The area grew until reaching the dimension of large wetlands in the lowest oasis zones, resulting from a larger runoff and soil saturation by the rise of the phreatic layers. This situation remained throughout the 19th century, affecting the extension and use of the available land for human activity. The purpose of this study was to research this process that culminated in 1930 with the partial desiccation of the area. We have given particular importance to the influence of the climatic fluctuations in the Cordillera de los Andes and to the consequent variations of the Rio Mendoza flow volume in this process. For the analysis we used snowfall series at the cordillera and flow volume of the Rio Mendoza, built by Prieto (2009) with documental data. We analyzed which were the mediate and immediate consequences of the growth and later desiccation of the wetlands over the environment and its present repercussion on the ecosystem (salinization, poor soil drainage, soil alkalinization, sedimentation). In addition, we have also worked over georeferenced historic charts that partially reflect the behavior of the Cienaga del Bermejo during the 18th, 19th and 20th centuries. This behavior characterized by "growth pulses" and retraction moments is reflected in the analyzed charts, where those moments of major growth coincide with cycles of bigger snowstorms and larger flow volume in the Rio Mendoza.

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

[Modern medicine environment and adaptation of Korean trader for medicinal herbs from the late 19th century to the early 20th 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

In South America (SA) several documentary based climate time series exist, some of them extending back to the 16th century. Most of these records end in the 19th century, and can not be calibrated against instrumental data. Here, we used the newspaper “Los Andes” from Mendoza, Argentina, to extend documentary based indices of Mendoza precipitation and Central Andes snow depth to the late 20th century. A statistical approach to create “pseudo documentary” 20th century data was applied to prolong eight other documentary records. Increased variability of the hydrological cycle in the Central Andes and prevailing periods of wet and dry years in Mendoza suggest that the 20th century is extraordinary in the context of the last 400 years. The final set of extended documentaries explains significant portions of SA precipitation variability in large areas between 20°S and 40°S and can therefore improve the network of annually resolved precipitation proxies.

Although recent historical ecology studies have extended quantitative knowledge of eastern Baltic cod (Gadus morhua) exploitation back as far as the 16th century, the historical origin of the modern fishery remains obscure. Widespread archaeological evidence for cod consumption around the eastern Baltic littoral emerges around the 13th century, three centuries before systematic documentation, but it is not clear whether this represents (1) development of a substantial eastern Baltic cod fishery, or (2) large-scale importation of preserved cod from elsewhere. To distinguish between these hypotheses we use stable carbon and nitrogen isotope analysis to determine likely catch regions of 74 cod vertebrae and cleithra from 19 Baltic archaeological sites dated from the 8th to the 16th centuries. δ13C and δ15N signatures for six possible catch regions were established using a larger sample of archaeological cod cranial bones (n = 249). The data strongly support the second hypothesis, revealing widespread importation of cod during the 13th to 14th centuries, most of it probably from Arctic Norway. By the 15th century, however, eastern Baltic cod dominate within our sample, indicating the development of a substantial late medieval fishery. Potential human impact on cod stocks in the eastern Baltic must thus be taken into account for at least the last 600 years. PMID:22110675

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

Lead concentrations and lead isotope ratios were analyzed in two firn/ice cores covering the period from 1650 to 1994, which were obtained from the 4450 m high glacier saddle Colle Gnifetti located in the Monte Rosa massif at the Swiss-Italian border. This study presents the first glaciochemical time series with annual resolution, spanning several centuries of lead concentrations and lead isotopic compositions in precipitation in Europe. Lead concentrations in firn dated from the 1970s are approximately 25 times higher than in ice dated from the 17th century, confirming the massive rise in lead pollution in Europe during the last few centuries. A decline of the lead concentration is then observed during the last two decades, i.e., from 1975 to 1994. The lead isotope ratio 206Pb/207Pb decreased from about 1.18 in the 17th and 18th centuries to about 1.12 in the 1970s. These variations are in good agreement with available information on variations in anthropogenic lead emissions from West European countries, especially from the use of lead additives in gasoline.

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

NASA Astrophysics Data System (ADS)

Borin, Maurizio; Novello, Elisabetta

2013-04-01

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

Anthropogenic lead inputs to the western Pacific during the 20th century.

Unlike in the North Atlantic, no continuous record of anthropogenic lead (Pb) has been available in the western Pacific. We reconstructed historical changes in anthropogenic Pb on the basis of Pb isotope ratios recorded in annually-banded coral retrieved from Ogasawara Island, Japan. Whereas the predominant natural source of Pb to the surface of the western Pacific apparently is Chinese loess, anthropogenic Pb has affected the western Pacific at least since the late 19th century. From the late 19th to the early 20th century, Australian Pb used in Japan was an important source of anthropogenic Pb. During 1920-1940, Pb emitted from parts of the world other than Japan contributed somewhat to the western Pacific, and the amount of Pb imported from Australia declined. Alkyl Pb used in Japan became the main source from 1950 until the mid-1970s, when leaded gasoline began to be regulated in Japan. Since the mid-1980s, aerosols from China have been the predominant source of Pb in the western Pacific. During the 1990s, around 60% of Pb in the surface of the western Pacific was from Chinese aerosols. We also investigated the present spatial distribution and likely sources of Pb in the western Pacific by using coral samples. Enrichment in 208Pb, which is a characteristic of Pb from China, was found in all coral samples except that from Pohnpei, Micronesia, suggesting that at present anthropogenic Pb is transported to the western Pacific mainly from China via westerly winds.

In the second edition of his Essay on the Principle of Population, Malthus included twelve chapters that offer a remarkable description of population dynamics from all corners of the world. His discussion of (sub-Saharan) Africa was almost entirely based on the travel accounts of James Bruce and Mungo Park, two late eighteenth century British explorers. In this essay, I introduce these sources and discuss the insights that Malthus did, or perhaps should have, derived from both. PMID:24259758

Sander, Sabine

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

The écorchés that Honoré Fragonard created between 1766 and 1771 have miraculously survived the ravages of time due to a technique of preparation which Fragonard never revealed. The present paper and a subsequent article aim to explain the classical methods used by anatomists of the 18th century (Part 1) and to throw light on the details of Fragonard's method (Part 2). Anatomists of the 18th century who wished to preserve their dissections used a method of mummification, which has now fallen into disuse: drying after immersion in alcohol. This article explains the stages of the classical method utilized by French anatomists of the Age of Enlightenment. The cadaver was selected with care before the vascular system was injected with a colored mixture of wax, animal fat, and plant resins. The body was then dehydrated by immersion in a bath of alcohol, after which it was removed and positioned by means of a wooden framework, which held the body in the desired pose while the alcohol evaporated. The vessels were painted, and finally the body was varnished. 2010 Wiley-Liss, Inc.

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

The ``System of Chymists'' and the ``Newtonian dream'' in Greek-speaking Communities in the 17th-18th Centuries

2008-06-01

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

Yersinia pestis, the etiologic agent of the disease plague, has been implicated in three historical pandemics. These include the third pandemic of the 19(th) and 20(th) centuries, during which plague was spread around the world, and the second pandemic of the 14(th)-17(th) centuries, which included the infamous epidemic known as the Black Death. Previous studies have confirmed that Y. pestis caused these two more recent pandemics. However, a highly spirited debate still continues as to whether Y. pestis caused the so-called Justinianic Plague of the 6(th)-8(th) centuries AD. By analyzing ancient DNA in two independent ancient DNA laboratories, we confirmed unambiguously the presence of Y. pestis DNA in human skeletal remains from an Early Medieval cemetery. In addition, we narrowed the phylogenetic position of the responsible strain down to major branch 0 on the Y. pestis phylogeny, specifically between nodes N03 and N05. Our findings confirm that Y. pestis was responsible for the Justinianic Plague, which should end the controversy regarding the etiology of this pandemic. The first genotype of a Y. pestis strain that caused the Late Antique plague provides important information about the history of the plague bacillus and suggests that the first pandemic also originated in Asia, similar to the other two plague pandemics.

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

USGS Publications Warehouse

Molnia, B.F.

2007-01-01

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

To estimate four radiomorphometric indices of mandibular bones in an 18th century population sample, and possibly associate the findings with bone mass loss related to sex, age, nutritional habits and pathologies reflecting on the bone. Thirty-six sculls (31 males, 5 females), recovered from the crypt of Požega Cathedral in Croatia were analyzed. Age estimation was based on tooth wear, and Eichner class was determined according to the number of occlusal supporting zones. The parameters in recording analogue orthopantomographs were set to constant current of 16 mA, exposure time of 14.1s, and voltage between 62-78 kV. Films were processed in an automatic dark chamber processor for 12 min, and digitized at 8-bit, 300 dpi. The thickness of the mandibular cortex was assessed below the mental foramen (MI), at antegonion (AI), at gonion (GI). Qualitative mandibular cortical index (MCI) was assessed. Average values of MI, AI and GI were 3.97 ± 0.94 mm, 2.98 ± 0.56 mm, and 1.99 ± 0.55 mm, respectively. Statistically significant differences between males and females were found for AI right (p=0.014), GI left (p=0.010) and GI average (p=0.006), and were in all cases higher in males. There were no statistically significant differences between age groups for either index (p>0.05). Considering Eichner classification the differences were not significant for MI (p=0.422), AI (p=0.516), and GI (p=0.443), but in Eichner classes II, MCI was significantly higher (p=0.02). The obtained data does not suggest generalized malnutrition or calcium, phosphorus and vitamin D deprivation in the historic population studied. Copyright © 2015 Elsevier Ltd. All rights reserved.

Technical improvements in 19th century Belgian window glass production

NASA Astrophysics Data System (ADS)

Lauriks, Leen; Collette, Quentin; Wouters, Ine; Belis, Jan

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.

Sea-surface temperature (SST) variability in the central tropical Pacific drives global-scale responses through atmospheric teleconnections, so the response of this region to anthropogenic forcing has important implications for regional climate responses in many areas. However, quantification of anthropogenic SST trends in the central tropical Pacific is complicated by the fact that instrumental SST observations in this region are extremely limited prior to 1950, with trends of opposite sign observed across the various gridded instrumental datasets (Deser et al., 2010). Researchers have turned to multi-century coral records to reconstruct ocean temperatures through time, but the paucity of such records prohibits the generation of uncertainty estimates. In this study, we use a large collection of U/Th-dated fossil corals that to investigate a new ensemble approach to reconstructing temperature from the Central Pacific over the late 20th century. Here we combine monthly-resolved d18O and Sr/Ca from 8 5-14 year long coral records from Christmas Island (2°N, 157°W) to quantify temperature and hydrological trends in this region from 1930 to present. We compare our fossil coral ensemble reconstruction to a long modern coral core from this site that extends back to 1940, as well as to gridded SST datasets. We also provide the first well-replicated coral d18O and Sr/Ca records across both the 1997/98 and 2015/2016 El Nino events, comparing the strength of these two events in the context of long-term temperature trends observed in our longer reconstruction. We conclude that the fossil coral ensemble approach provides a robust means of reconstructing 20th century climate trends. Deser et al., 2010, GRL, doi: 10.1029/2010GL043321

Early 20th century untrained nursing staff in the Rockhampton district: a necessary evil?

PubMed

Madsen, Wendy

2005-08-01

This paper explores the role of untrained nursing staff within the nursing services of the Rockhampton region, Queensland, Australia, throughout the early 20th century. It details who these nurses were, where they worked and how their work was affected by factors such as legislation and social changes. Despite the increasing prevalence of trained nurses from the late 19th century, nurses who had never undergone any formal training continued to gain work in hospitals, institutions and their local communities. This paper is an historical analysis of a wide range of primary source material relating to untrained nursing staff. The primary source material used related specifically to a limited geographical region in Australia. Untrained nursing staff primarily worked as private duty nurses at the beginning of the 20th century. However, as the century progressed, their opportunities to work as untrained nursing staff tended towards institutions dealing with the chronically ill and the aged. As a result of this transition, their profile altered from that of a married/widowed woman living at home with dependents to one who could live on-site at the institution with no dependents. Furthermore, the level of autonomy of the untrained nurse decreased dramatically throughout this period from being relatively independent to being under the control of a trained nurse within the institution. Consideration of the historical evolution of untrained nursing staff challenges some of the assumptions made about this category of nurse, assumptions that can affect current relationships between professional nurses and others who undertake nursing work.

American medical students in 19th-century Europe.

Many Americans studied medicine in Britain in the 18th century, but the major influx to Europe began after 1815, when the French Revolution's reforms of health care and medical teaching had reached their zenith. Americans were well trained in France (and later in Germany) in medicine, surgery, pathology and clinical science, and brought these skills back to the US. Their training had been in countries with government-run, relatively egalitarian health care systems. On their return, they did not seek to transplant such a system to the US, but they did introduce European medical science and medical techniques, and something of the European medical education system.

Music therapy in the 19th century America.

PubMed

Davis, W B

1987-01-01

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

[Changes of medico-pharmaceutical profession and private practice from the late 19th century to the early 20th century: ebb and flow of western pharmacies and clinics attached to pharmacy].

PubMed

Lee, Heung-Ki

2010-12-31

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

Early 20th century conceptualization of health promotion.

PubMed

Madsen, Wendy

2017-12-01

This historical analysis of the term 'health promotion' during the early 20th century in North American journal articles revealed concepts that strongly resonate with those of the 21st century. However, the lineage between these two time periods is not clear, and indeed, this paper supports contentions health promotion has a disrupted history. This paper traces the conceptualizations of health promotion during the 1920s, attempts to operationalize health promotion in the 1930s resulting in a narrowing of the concept to one of health education, and the disappearance of the term from the 1940s. In doing so, it argues a number of factors influenced the changing conceptualization and utilization of health promotion during the first half of the 20th century, many of which continue to present times, including issues around what health promotion is and what it means, ongoing tensions between individual and collective actions, tensions between specific and general causes of health and ill health, and between expert and societal contributions. The paper concludes the lack of clarity around these issues contributed to health promotion disappearing in the mid-20th century and thus resolution of these would be worthwhile for the continuation and development of health promotion as a discipline into the 21st century. © The Author 2016.

Kostyuk, A V

2015-09-01

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

Evidence for Precise Calendrical Observations in the 17th Century at the `Bruchhauser Steine', Olsberg, Northrhine-Westphalia, Germany

NASA Astrophysics Data System (ADS)

Steinrücken, B.

The `Bruchhauser Steine', four large rocks of volcanic origin in southern Westphalia, form perfect foresights for calendrical observations from the surrounding country. The ancient walls and embankments on the `Istenberg' with the rocks as cornerstones were built 500 BC. In the landscape are placed shrines with images of Christian saints, erected in the late 17th and the early 18th century. The positions of these shrines can be interpreted as observing sites with respect to the stones. The foresights reach several degrees to the sky, so variations in the astronomical refraction are strongly suppressed. The most impressive observing site with a shrine of 1699 (8o31'13'' E, 51o18'49'' N) is exactly at the position to observe the summer solstice sunrise at the topmost rock, the `Feldstein'. The solstice sun rises between two stones and grazes the Feldstein at 6:20 CEST. Today the sun is obstructed 2'-3' by the stone. Taking into account the slight variation of the obliquity of the ecliptic of 2' since 1699 the grazing procedure at the time of erection was perfect, without any obstruction of the suns disc. Similar shrines are placed at positions to observe the sunrise on May 1st in the identical manner (8o29'39'' E, 51o18'41'' N) and the lunar declination minimum on the meridian (8o32'44'' E, 51o20'33'' N). Some evidence indicates a prehistoric origin of this calendrical system.

Medicinal herbs for the treatment of rheumatic disorders--a survey of European herbals from the 16th and 17th century.

Adams, Michael; Berset, Caroline; Kessler, Michael; Hamburger, Matthias

2009-01-30

From the 16th up into the 18th century botanical and medicinal knowledge in Europe was documented and spread in magnificently illustrated herbals. For the most part modern science has neglected this source of knowledge and old remedies have not been systematically evaluated pharmacologically. Rheumatic disorders and chronic inflammatory and degenerative diseases of the musculoskeletal system were chosen in an attempt to discuss remedies described in the old herbals in the viewpoint of modern science. Five of the most important European herbals of the 16th and 17th century were searched for terms related to rheumatic diseases, and plants and recipes described for their treatment. An extensive search of the scientific data banks Medline and SciFinder scholar was done to find recent results concerning the phytochemistry and possible antiphlogistic activities of the plants. Sixty-three plants were identified in the herbals for this indication. More than half of them have shown in vitro or in vivo antiphlogistic activities. European herbals may be a valuable source of information for the selection of plants for focussed screening programmes. Information contained in these herbals should be explored in a systematic manner.

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.

Rapid landscape change in 6th century northern Jordan: interdisciplinary geoarchaeological perspectives

NASA Astrophysics Data System (ADS)

Lucke, Bernhard

2016-04-01

Landscapes of the ancient fertile crescent are considered affected by soil degradation as result of long-term farming since the Neolithic, and impressive ruins of antiquity led to assumptions that their abandonment must have been conntected with reduced agricultural productivity. In this context, a valley fill near the site of Abila of the Decapolis in northern Jordan was apparently deposited largely during the 6th century AD, and provides evidence for a rapid and intense landscape change during the Late Byzantine period. However, an interdisciplinary case study of land use, soil development, and sediments found that the valley fill cannot be connected with large-scale soil erosion in the vicinity of the site. On the one hand, this is indicated by the distribution of soil development and archaeological material as marker of past land use activity in the past, which suggests that the best soils were and still are used intensively. On the other hand, the sediments seem to point to the occurrence of climatic extremes such as heavy floods, the occurrence of soil creep after water saturation, but also a significant shift to aridity which may have triggered socio-economic changes of subsistence strategies from agriculture to pastoralism. The dates of sediments which are available so far indicate that the climatic change seemingly occurred rapidly within approximately 100 years during the late 6th and early 7th century AD, possibly connected with the "year without sun" or 'Mystery Veil' which the Byzantine historian Procopius described in the year 536 AD. Modern analogies of the Pinatubo eruption in 1991 let it seem possible that a volcanic event, perhaps the outbreak of the Ilopango volcano, was connected with these environmental turbulences. Such events cannot be understood by isolated studies: without a broad interdisciplinary framework, single archives are prone to misinterpretation, and our understanding of the environmental history of Abila is still very limited.

Normativity in 18th century discourse on speech.

PubMed

MacNamee, T

1984-11-01

Eighteenth century phoneticians, such as Dodart, Ferrein, and Hellwag, extended the taxonomy of visible articulatory processes into the realm of the invisible, notably with the exploration of the voicing mechanism. Remedial initiatives were not simply confined to consideration of the outward manifestations of speech and its disorders: The work of Haller, Kuestner, and Morgagni shows an acute awareness of the nervous organization underlying verbal behavior. There was a characteristic preoccupation with mechanical models of speech, which led to the attempts of Kempelen and other investigators to construct actual "speaking machines." Eighteenth century scholars regarded language as not only an innate capacity peculiar to human nature, but also as a bodily habit learned by experience. The function of the orthoepist was to teach the right speech habits, and the upward mobility of the bourgeoisie created a demand for his services.

Bites, nibbles, sips and puffs: new exotic goods in Norway in the 18th and the first half of the 19th century.

Hutchison, Ragnhild

2011-01-01

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

The 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

What was Glaucoma Called Before the 20th Century?

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

Smallpox holds a unique position in the history of medicine. It was the first disease for which a vaccine was developed and remains the only human disease eradicated by vaccination. Although there have been claims of smallpox in Egypt, India, and China dating back millennia [1-4], the timescale of emergence of the causative agent, variola virus (VARV), and how it evolved in the context of increasingly widespread immunization, have proven controversial [4-9]. In particular, some molecular-clock-based studies have suggested that key events in VARV evolution only occurred during the last two centuries [4-6] and hence in apparent conflict with anecdotal historical reports, although it is difficult to distinguish smallpox from other pustular rashes by description alone. To address these issues, we captured, sequenced, and reconstructed a draft genome of an ancient strain of VARV, sampled from a Lithuanian child mummy dating between 1643 and 1665 and close to the time of several documented European epidemics [1, 2, 10]. When compared to vaccinia virus, this archival strain contained the same pattern of gene degradation as 20 th century VARVs, indicating that such loss of gene function had occurred before ca. 1650. Strikingly, the mummy sequence fell basal to all currently sequenced strains of VARV on phylogenetic trees. Molecular-clock analyses revealed a strong clock-like structure and that the timescale of smallpox evolution is more recent than often supposed, with the diversification of major viral lineages only occurring within the 18 th and 19 th centuries, concomitant with the development of modern vaccination.

We present paleoclimate evidence for rapid (< 100 years) shifts of ~2-4oC in Chesapeake Bay (CB) temperature ~2100, 1600, 950, 650, 400 and 150 years before present (years BP) reconstructed from magnesium/calcium (Mg/Ca) paleothermometry. These include large temperature excursions during the Little Ice Age (~1400-1900 AD) and the Medieval Warm Period (~800-1300 AD) possibly related to changes in the strength of North Atlantic thermohaline circulation (THC). Evidence is presented for a long period of sustained regional and North Atlantic-wide warmth with low-amplitude temperature variability between ~450 and 1000 AD. In addition to centennial-scale temperature shifts, the existence of numerous temperature maxima between 2200 and 250 years BP (average ~70 years) suggests that multi-decadal processes typical of the North Atlantic Oscillation (NAO) are an inherent feature of late Holocene climate. However, late 19th and 20th century temperature extremes in Chesapeake Bay associated with NAO climate variability exceeded those of the prior 2000 years, including the interval 450-1000 AD, by 2-3oC, suggesting anomalous recent behavior of the climate system.

Commercial hunting for the international trade in animal hides in the 20th century decimated many populations of aquatic wildlife in Amazonia. However, impacts varied significantly between different species and regions, depending upon hunting intensity, accessibility of habitat, and the inherent resilience of various species and their habitats. We investigated the differential responses of two Amazonian Mustelid species, the neotropical otter and giant otter, to commercial hunting pressure along the upper Rio Negro in Brazil, and examined historical factors that influenced spatial and temporal variation in commercial exploitation. We analyzed previously unanalyzed data from historical records of hide shipments to track changes in hide sales and prices for the two species in the late 20th century. We also gathered oral histories from older Baniwa people who had witnessed or participated in commercial otter hunting. These complimentary data sources reveal how intrinsic biological and social characteristics of the two otter species interacted with market forces and regional history. Whereas giant otter populations were driven to local or regional extinction during the late 20th century by commercial hunting, neotropical otters persisted. In recent decades, giant otter populations have returned to some parts of the upper Rio Negro, a development which local people welcome as part of a generalized recovery of the ecosystems in their territory as a result of the banning of animal pelt exports and indigenous land demarcation. This paper expands the scope of the field historical ecology and reflects on the role of local knowledge in biodiversity conservation.

PubMed

Gantet, Claire

Neither pedants nor amateurs? Psychological journals in Germany in the last three decades of the 18th century The Magazin zur Erfahrungsseelenkunde introduced a new tone in the evolving field of psychology. For the first time, attention was paid not to the abstract relationships between body and soul, but to suffering individuals from the «common folk». The collection and systematic publication of accounts of readers should eventually allow the formulation of an empirical «science of the soul». The readers would eventually send accounts of personal and experienced «cases». By 1800, this conception of the science of psychology was called into question by educated philosophers who, in journals opened only to specialists, endeavored to develop a more professional psychology. They nevertheless failed in formulating general criteria of scientificity. The main argument of this article is that the distinction between amateurs and scientists was not an outcome of the inner evolution of the field of psychology, but that it developed through practices of communication in which periodicals play a major role.

Evidence of Regional Warming during the 20th Century in Alpine and Subalpine Lakes in the Western United States

Subfossil midge analyses have been used to develop high-resolution (sub-decadal) reconstructions of 20th century temperature change in the Sierra Nevada, CA with success. Expansion of this earlier work to additional sites in the western United States suggests that a widespread increase in lake water temperatures has occurred in this region during the late 20th and early 21st centuries. Inference models for summer surface water temperature (SSWT) were developed combining midge abundance data from 56 lakes in the eastern Sierra Nevada, California, with subfossil midge remains from the Uinta Mountains, UT. The newly merged Sierra Nevada-Uinta Mountains calibration set contains a greater diversity of chironomid assemblages and spans a wider SSWT range than the previously published Sierra Nevada calibration set. The lakes in the merged calibration set spanned elevation, depth, and SSWT temperature ranges of 900 m, 12.7 m, and 11.3 °C, respectively. A robust inference model for SSWT (3-component WA-PLS), based on 90 lakes, had a high coefficient of determination (r2jack = 0.66) and a low RMSEP (1.4 °C). The midge-based SSWT inference model was applied to subfossil chironomid remains extracted from well-dated sediment sequences recovered from alpine and subalpine lakes in the Sierra Nevada, CA, Snake Range, NV and Uinta Mountains, UT. A close correspondence exists between the chironomid-inferred temperature profiles for the 20th and 21st centuries and mean July or summer temperatures measured at nearby meteorological stations. Application of this midge-based SSWT inference model to other intact, late Quaternary sedimentary sequences found in subalpine and alpine lakes in the Great Basin will help resolve the impact of late Quaternary and recent climate change in this region, improve our understanding of regional climate and aquatic ecosystem variability, and can be used to monitor the effects of climate change on aquatic ecosystems and establish 'baseline' conditions

Astronomical dating in the 19th century

Hilgen, Frederik J.

2010-01-01

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

We present the results of the surveys on sunspots and auroral candidates in Rikkokushi, Japanese official histories from the early 7th century to 887, to review the solar and auroral activities. In total, we found one sunspot record and 13 auroral candidates in Rikkokushi. We then examine the records of the sunspots and auroral candidates, compare the auroral candidates with the lunar phase to estimate their reliability, and compare the records of the sunspots and auroral candidates with the contemporary total solar irradiance reconstructed from radioisotope data. We also identify the locations of the observational sites to review possible equatorward expansion of the auroral oval. These discussions suggest a major gap in auroral candidates from the late 7th to early 9th centuries, which includes the candidate of the grand minimum reconstructed from the radioisotope data, a similar tendency as the distributions of sunspot records in contemporary China, and a relatively high magnetic latitude of observational sites with a higher potential for observing aurorae more frequently than at present.

The ancient Roman city of Complutum (Alcalá de Henares, Madrid), founded in the 1st century AD, was one of the most important cities of Hispania. The old Roman city was destroyed, abruptly abandoned, relocated close by and rebuilt during the late 4th century AD. Destruction of the city and its relocation has not yet been explained by archaeologists. In this paper, with our multidisciplinary approach, we identify and characterize earthquake archaeological effects (EAEs) affecting the archaeological site, the La Magdalena, an agricultural holding 4 km from the core of Complutum. The most important EAEs in the site are liquefactions (sand dikes and explosive sand-gravel craters) affecting Roman structures, such as water tanks (cisterns), houses and graves. Ground liquefaction generated significant ground cracks, explosive craters and folds in foundations of buildings. Several other Roman sites throughout the valley were also abandoned abruptly during the 4th century AD, in some cases with EAEs of similar origin. This suggests the occurrence of a 5.0-6.6 Mw seismic event in the zone, in accordance with the minimum empirical limit of seismically-induced liquefaction and the maximum surface rupture length of the Henares fault.

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.

The Hungarians conquered the Carpathian Basin 895-907 AD, and admixed with the indigenous communities. Here we present mitochondrial DNA results from three datasets: one from the Avar period (7(th)-9(th) centuries) of the Carpathian Basin (n = 31); one from the Hungarian conquest-period (n = 76); and a completion of the published 10(th)-12(th) century Hungarian-Slavic contact zone dataset by four samples. We compare these mitochondrial DNA hypervariable segment sequences and haplogroup results with published ancient and modern Eurasian data. Whereas the analyzed Avars represents a certain group of the Avar society that shows East and South European genetic characteristics, the Hungarian conquerors' maternal gene pool is a mixture of West Eurasian and Central and North Eurasian elements. Comprehensively analyzing the results, both the linguistically recorded Finno-Ugric roots and historically documented Turkic and Central Asian influxes had possible genetic imprints in the conquerors' genetic composition. Our data allows a complex series of historic and population genetic events before the formation of the medieval population of the Carpathian Basin, and the maternal genetic continuity between 10(th)-12(th) century and modern Hungarians.

The inquisitorial trial of a cross-dressing lesbian: reactions and responses to female homosexuality in 18th-century portugal.

PubMed

Soyer, François

2014-01-01

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

Making a stand: five centuries of population growth in colonizing populations of Pinus ponderosa.

Lesser, Mark R; Jackson, Stephen T

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

The author illustrates the relations in Italy between industry and the medical-hygienic situation in the XIX century. Italy started industrial processes rather late, about 1840, and between 1840 and 1870, for the first time, a remarkable quantity of publications about working class life conditions appeared. Special attention was given to spinning-mill workers, who - as Tonini, Ripa and Bonomi describe in their treatises - suffered a very hard life and working conditions, cold, damp, a very poor diet based on stale bread; furthermore, women had dangerous pregnancies and their babies were extremely undernourished, because of bottle-feeding caused by the impossibility of mothers to take their infants with them. These conditions produced numerous gastric, rheumatic and respiratory diseases. At the end of the XIX century, Mantegazzaa defined, for the first time, professional diseases from a clinical and social point of view. Investigations acquired a more rigorous and scientific character by dividing into a series of subjects such as, for instance, the study of "unhealthy industries." Legislation was adapted quite late, and produced in 1888 the "Crispi act".

Endless cold: a seasonal reconstruction of temperature and precipitation in the Burgundian Low Countries during the 15th century based on documentary evidence

2015-03-01

This paper applies the methods of historical climatology to present a climate reconstruction for the area of the Burgundian Low Countries during the 15th century. The results are based on documentary evidence that has been handled very carefully, especially with regard to the distinction between contemporary and non-contemporary sources. Approximately 3000 written records deriving from about 100 different sources were examined and converted into seasonal seven-degree indices for temperature and precipitation. For the Late Middle Ages only a few climate reconstructions exist. There are even fewer reconstructions which include winter and autumn temperature or precipitation at all. This paper therefore constitutes a useful contribution to the understanding of climate and weather conditions in the less well researched but highly interesting 15th century.

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

Local censuses in the 18th century.

Abstract Recent work on the population problems of the eighteenth century has been mainly based on the use of parish records. Another source, and one which, surprisingly, has received little attention is the local census. These are more numerous than is generally realised; and can be of great use in demographic studies. This paper examines 125 local censuses mainly taken in urban areas. They are discussed in terms of how they come to be taken, their reliability, extant manuscript material and their contents. Whilst most of the censuses confine themselves to the basic facts such as total population, number of houses and number of families, some give details of sex, age, marital status and occupation. Generally the information is given for the parish or local administrative unit, but in a few instances it is available by streets.

The Lowland Rivers of The Netherlands - Geodiversity and Cultural Heritage on 19th and early 20th century Landscape Paintings

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

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

NASA Astrophysics Data System (ADS)

Carducci, Christiane M.

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

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.

This study aims to examine the beginning and the development of Christian Charities during the 4(th)-6(th) centuries which would eventually result in the birth of the hospital in modern sense in the first half of the 7(th) century. For this purpose, I looked carefully into various primary sources concerning the early Christian institutions for the poor and the sick. Above all, it's proper to note that the first xenodocheion where hospitality was combined with a systematic caring, is concerned with the Trinitarian debate of the 4(th) century. In 356, Eustathios, one of the leaders of homoiousios group, established xenodocheion to care for the sick and the lepers in Sebaste of Armenia, whereas his opponent Aetios, doctor and leader of the heteroousios party, was reckoned to have combined the medical treatment with his clerical activities. Then, Basil of Caesarea, disciple of Eustathios of Sebaste, also founded in 372 a magnificent benevolent complex named 'Basileias' after its founder. I scrupulously analysed several contemporary materials mentioning the charitable institution of Caesarea which was called alternatively katagogia, ptochotropheion, xenodocheion. John Chrysostome also founded several nosokomeia in Constantinople at the end of the 4(th) century and the beginning of the 5(th) century. Apparently, the contemporary sources mention that doctors existed for these Charities, but there is no sufficient proof that these 'Christian Hospitals,' Basileias or nosokomeia of Constantinople were hospitals in modern sense. Imperial constitutions began to mention ptochotropheion, xenodocheion and orphanotropheion since the second half of the 5(th) century and then some Justinian laws evoked nosokomium, brephotrophia, gerontocomia. These laws reveal that 'Christian Hospitals' were well clarified and deeply rooted in Byzantine society already in these periods. And then, new benevolent institutions emerged in the 6(th) century: nosokomeia for a specific class and

Oysters (Crassostrea virginica) were a central component of the Chesapeake Bay ecosystem in 1607 when European settlers established Jamestown, VA, the first permanent English settlement in North America. These estuarine bivalves were an important food resource during the early years of the James Fort (Jamestown) settlement while the colonists were struggling to survive in the face of inadequate supplies and a severe regional drought. Although oyster shells were discarded as trash after the oysters were eaten, the environmental and ecological data recorded in the bivalve geochemistry during shell deposition remain intact over centuries, thereby providing a unique window into conditions during the earliest Jamestown years. We compare oxygen isotope data from these 17th century oyster shells with modern shells to quantify and contrast estuarine salinity, season of oyster collection, and shell provenance during Jamestown colonization (1609-1616) and the 21st century. Data show that oysters were collected during an extended drought between fall 1611 and summer 1612. The drought shifted the 14 psu isohaline above Jamestown Island, facilitating individual oyster growth and extension of oyster habitat upriver toward the colony, thereby enhancing local oyster food resources. Data from distinct well layers suggest that the colonists also obtained oysters from reefs near Chesapeake Bay to augment oyster resources near Jamestown Island. The oyster shell season of harvest reconstructions suggest that these data come from either a 1611 well with a very short useful period or an undocumented older well abandoned by late 1611.

Little is known about late 19th and early 20th century BMIs on the US Central Plains. Using data from the Nebraska state prison, this study demonstrates that the BMIs of dark complexioned blacks were greater than for fairer complexioned mulattos and whites. Although modern BMIs have increased, late 19th and early 20th century BMIs in Nebraska were in normal ranges; neither underweight nor obese individuals were common. Farmer BMIs were consistently greater than those of non-farmers, and farm labourer BMIs were greater than those of common labourers. The BMIs of individuals born in Plains states were greater than for other nativities, indicating that rural lifestyles were associated with better net current biological living conditions.

From antiquity up into the 20th century tertian and quartan malaria which are caused by the parasites Plasmodium vivax and Plasmodium malariae were widespread in Central Europe. Hundreds of different remedies against malaria can be found in herbals from the Renaissance. To document and discuss from a modern pharmacological viewpoint the old remedies described in eight 16th and 17th century herbals written in German. Eight of the most important herbals of the 16th and 17th century including Bock (1577), Fuchs (1543), Matthiolus (1590), Lonicerus (1560), Brunfels (1532), Zwinger (1696), and Tabernaemontanus (1591 and 1678) were searched for terms related to malaria, and documented plants and recipes described for its treatment. Additionally the overlapping of these remedies with those in De Materia Medica by the Greek physician Dioscorides was studied. Three hundred and fourteen taxa were identified in the herbals for this indication. Recent pharmacological data was found for just 5% of them. The influence of De Materia Medica was shown to be negligible with only 3.5% of the remedies in common. European Renaissance herbals may be a valuable source of information for the selection of plants for focussed antiplasmodial screening programmes, but have received only little scientific attention. Antimalarial remedies from these herbals must be viewed as independent sources of knowledge separate from Dioscorides' De Materia Medica. Copyright © 2010 Elsevier Ireland Ltd. All rights reserved.

Observed 20th Century Desert Dust Variability: Impact on Climate and Biogeochemistry

2010-01-01

Desert dust perturbs climate by directly and indirectly interacting with incoming solar and outgoing long wave radiation, thereby changing precipitation and temperature, in addition to modifying ocean and land biogeochemistry. While we know that desert dust is sensitive to perturbations in climate and human land use, previous studies have been unable to determine whether humans were increasing or decreasing desert dust in the global average. Here we present observational estimates of desert dust based on paleodata proxies showing a doubling of desert dust during the 20th century over much, but not all the globe. Large uncertainties remain in estimates ofmore » desert dust variability over 20th century due to limited data. Using these observational estimates of desert dust change in combination with ocean, atmosphere and land models, we calculate the net radiative effect of these observed changes (top of atmosphere) over the 20th century to be -0.14 {+-} 0.11 W/m{sup 2} (1990-1999 vs. 1905-1914). The estimated radiative change due to dust is especially strong between the heavily loaded 1980-1989 and the less heavily loaded 1955-1964 time periods (-0.57 {+-} 0.46 W/m{sup 2}), which model simulations suggest may have reduced the rate of temperature increase between these time periods by 0.11 C. Model simulations also indicate strong regional shifts in precipitation and temperature from desert dust changes, causing 6 ppm (12 PgC) reduction in model carbon uptake by the terrestrial biosphere over the 20th century. Desert dust carries iron, an important micronutrient for ocean biogeochemistry that can modulate ocean carbon storage; here we show that dust deposition trends increase ocean productivity by an estimated 6% over the 20th century, drawing down an additional 4 ppm (8 PgC) of carbon dioxide into the oceans. Thus, perturbations to desert dust over the 20th century inferred from observations are potentially important for climate and biogeochemistry, and our

Physics of the 20th century has contributed significantly to modern technology, and yet many physics students are never availed the opportunity to study it as part of the curriculum. One of the possible reasons why it is not taught in high school and introductory physics courses could be because curriculum designers believe that students need a solid background in classical mechanics and calculus in order to study physics of the 20th century such as the photoelectric effect, special and general relativity, the uncertainty principle, etc. This presumption may not be justifiable or valid. The authors of this paper contend that teaching physics of the 20th century aids students in relating physics to modern technology and the real world, making studying physics exciting. In this study, the authors correlated scores for matched questions in the Mechanics Baseline Test and a physics of the 20th century test in order to examine the trend of the scores. The participants included undergraduate students attending an introductory algebra-based physics course with no intention of taking physics at a higher level. The analysis of the scores showed no significant correlation for any of the matched pairs of questions. The purpose of this article is to recommend that even without a solid background in classical mechanics, teachers can introduce physics of the 20th century to their students for increased interest.

We present the results of an anthropological and paleopathological analysis of 7 graves discovered at the site of a church-hospital complex existing in the 14th-18th century in Łeczyca (province of Łódź). The aim was to determine whether the skeletons revealed features typical for the function of the complex. The graves contained the remains of 8 persons: 4 men (2 of them aged 20-40 years and 2 aged 40-60 years), 2 women (aged 40-60 years), and 2 children (one aged 2-4 years and a 10-month-old fetus or neonate buried together with one of the women). Four skeletons of adults (out of 5 skeletons in a condition adequate for the study) showed pathological (degenerative) and traumatic lesions. Pathologies of the masticatory organ (mainly intravital loss of teeth and recession of the alveolar process) were seen in all preserved adult skulls. The high incidence of pathologies indicates that we were dealing with the remains of patients of a hospital.

As a consequence of several battles that were fought in its vicinity, the site was abandoned in the 16th century and was not occupied since then. It is one of the rare archaeological sites in Europe that contains a significant amount of information on the daily life inside a small but affluent medieval community. A comparison of the chemical composition of fragments of vessels and window glass encountered in Raversijde to those found in urban centres in Belgium and to literature date on German and French archaeological finds shows that glass made with wood ash dominates. Usually, it concerns artifacts with a predominantly utilitarian use. A few objects made with sodic (i.e., Na-rich) glass were also encountered, likely to have been imported from Venice during the 15th century or in later periods from an urban centre such as Antwerp, where Façon-de-Venice glass manufacturing activities were established near the start of the 16th century.

There were remarkable achievements in the 19th century in our understanding of the cells of the allergic response, the clear descriptions of hay fever and asthma, as well as the role of pollen in seasonal rhinitis. Although allergy as a concept was not developed until well into the 20th century, the foundations of our present understanding of these diseases were laid in the 1800s. The outstanding physicians and scientists of this time included Paul Ehrlich (who described mast cells, eosinophils and basophils), John Bostock (who provided the first detailed account of hay fever), Charles Blackley (who showed that pollen was the cause of hay fever), Morrill Wyman (who demonstrated that autumnal catarrh was due to ragweed pollen), Henry Hide Salter (who made the first classic description of asthma) and Henri Laënnec (the inventor of the stethoscope). © 2014 S.

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

We present a new commentary on Robert Grosseteste’s De colore, a short treatise that dates from the early 13th century, in which Grosseteste constructs a linguistic combinatorial account of color. In contrast to other commentaries (e.g., Kuehni & Schwarz, Color Ordered: A Survey of Color Order Systems from Antiquity to the Present, 2007, p. 36), we argue that the color space described by Grosseteste is explicitly three-dimensional. We seek the appropriate translation of Grosseteste’s key terms, making reference both to Grosseteste’s other works and the broader intellectual context of the 13th century, and to modern color spaces.

Centenarian scientists: an unusual cluster newly formed in the 20th century.

From biographical data sources on ranking scientists, I was able to identify 35 centenarians. Among these, only one (Michel Chevereul from France) lived before the 20th century. Since the remaining 34 individuals became centenarians only from 1965, I propose that centenarian scientists are an unusual cluster, first formed in the 20th century. Among these, all except one (Alice Hamilton) were men. Six centenarian scientists, including Hamilton, had received professional medical training. The nationality ranks of the 34 centenarian scientists identified in the 20th century show 26 Americans, 6 British, one German and one French. Four of the 26 Americans were immigrants from Europe. At least three centenarians, namely Michael Heidelberger, Nathaniel Kleitman and Victor Hamburger, belong to the 'Nobel class' category, being pioneers in the disciplines of immunochemistry, sleep physiology and neuroembryology respectively.

Final Scientific Report for "The Interhemispheric Pattern in 20th Century and Future Abrupt Change in Regional Tropical Rainfall"

2012-10-29

This is the final scientific report for grant DOE-FG02-08ER64588, "The Interhemispheric Pattern in 20th Century and Future Abrupt Change in Regional Tropical Rainfall."The project investigates the role of the interhemispheric pattern in surface temperature – i.e. the contrast between the northern and southern temperature changes – in driving rapid changes to tropical rainfall changes over the 20th century and future climates. Previous observational and modeling studies have shown that the tropical rainband – the Intertropical Convergence Zone (ITCZ) over marine regions, and the summer monsoonal rainfall over land – are sensitive to the interhemispheric thermal contrast; but that the linkmore » between the two has not been applied to interpreting long-term tropical rainfall changes over the 20th century and future.The specific goals of the project were to i) develop dynamical mechanisms to explain the link between the interhemispheric pattern to abrupt changes of West African and Asian monsoonal rainfall; ii) Undertake a formal detection and attribution study on the interhemispheric pattern in 20th century climate; and iii) assess the likelihood of changes to this pattern in the future. In line with these goals, our project has produced the following significant results: 1.We have developed a case that suggests that the well-known abrupt weakening of the West African monsoon in the late 1960s was part of a wider co-ordinated weakening of the West African and Asian monsoons, and driven from an abrupt cooling in the high latitude North Atlantic sea surface temperature at the same time. Our modeling work suggests that the high-latitude North Atlantic cooling is effective in driving monsoonal weakening, through driving a cooling of the Northern hemisphere that is amplified by positive radiative feedbacks. 2.We have shown that anthropogenic sulfate aerosols may have partially contributed to driving a progressively southward displacement of the Atlantic

This study details a severe case of Scheuermann's disease (SD) in a well-preserved skeleton of a juvenile male (designated TOR302), dated to 3rd-4th century CE, from the late Roman necropolis of Torrenueva (Granada, Spain). Individual TOR302 shows an evident kyphotic curve in the thoraco-lumbar spine, which is characterised by: (i) vertebral bodies of thoracic vertebra T2, thoracic segment T4-T9, and thoraco-lumbar segment T12-L2 wedged at >5°; (ii) slight anterior extensions of the epiphyseal ring; (iii) Schmorl's nodes on the superior and/or inferior plates; and (iv) a Cobb angle of 75°, derived from thoracic segments T4-T9. In addition, TOR302 shows other skeletal malformations as the secondary results of abnormal growth, due to altered biomechanical forces imposed by the spinal deformity, including: (i) lateral distortion of the spine that causes a slight secondary scoliotic curve; (ii) pelvic obliquity; and (iii) discrepancy in the length of the limbs. We argue that the secondary skeletal abnormalities allowed the individual to adapt to his spinal deformity meaning he was able to walk without the aid of a stick. Despite SD being a common modern clinical finding, few cases have been reported in ancient skeletal remains. This case therefore represents an important contribution to the palaeopathological literature. Copyright © 2017 Elsevier Inc. All rights reserved.

Introduction. Towards a Contemporary Historiography of Amateurs in Science (18th–20th Century).

PubMed

Guillemain, Hervé; Richard, Nathalie

The last few decades have seen considerable growth in the role played by amateurs in the sciences. With the development of new techniques for collecting information, new virtual networks and the emergence of new problematics calling for the participation of citizens, this role has also become more visible, while the modern boundary between professionalism and amateurism, first erected in the 19th century, has been shaken. These contemporary developments have changed our perspective on amateurs in science and brought forth questions and analyses that sometimes coincide with recent inflections in the history of science. Thus it is now possible to take a new approach to the historical study of amateurs in contemporary science. This introduction hopes to demonstrate this, while the essays brought together in this volume, some of which explore extreme cases, reveal the very relative nature of the definition of the “amateur” category and how complex and fertile its implementation has been in the history of science.

A Revised Estimate of 20th Century Global Mean Sea Level

NASA Astrophysics Data System (ADS)

Hay, C.; Morrow, E.; Kopp, R. E., III; Mitrovica, J. X.

2014-12-01

One of the primary goals of paleo-sea level research is to assess the stability of ice sheets and glaciers in warming climates. In this context, the 20th century may be thought of as the most recent, recorded, and studied of all past episodes of warming. Over the past decade, a consensus has emerged in the literature that 20th century global mean sea level (GMSL), inferred from tide gauge records, rose at a mean rate of 1.6-1.9 mm/yr. This sea-level rise can be attributed to multiple sources, including thermal expansion of the oceans, ice sheet and glacier mass flux, and anthropogenic changes in land water storage. The Fifth Assessment Report of the IPCC summarized the estimated contributions of these sources over 1901-1990 and computed a total rate, using a bottom-up approach, of ~1.0 mm/yr, which falls significantly short of the rate inferred from tide gauge records. Using two independent probabilistic approaches that utilize models of glacial isostatic adjustment, ocean dynamics, and the sea-level fingerprints of rapid land-ice melt to analyze tide gauge records (Kalman smoothing and Gaussian process regression), we are able to close the 20th century sea-level budget and resolve the above enigma. Our revised estimate for the rate of GMSL rise during 1901-1990 is 1.1-1.3 mm/yr (90% credible interval). This value, which is ~20-30% less than previous estimates, suggests that the change in the GMSL rate from the 20th century to the last two decades (2.7 ± 0.4 mm/yr, consistent with past estimates) was greater than previous estimates. Moreover, since some forward projections of GMSL change into the next century are based in part on past estimates of GMSL change, our revised rate may impact projections of GMSL rise for the 21st century and beyond.

Brutal and negligent? 19th century factory mothers and child care.

PubMed

Reynolds, Melanie

2011-10-01

This paper aims to highlight some working class women's childcare practices in northern industrial areas of Britain during the latter half of the 19th century. It aims to challenge the commonly held belief that 19th century northern working-class factory mothers were irresponsive and neglectful toward their infants, thereby fuelling the high northern infant mortality rate. It will do this by showing that factory mothers were responsible and responsive toward their infants despite being thwarted by the working patterns of industrialisation. It begins by outlining the arguments made by historians that northern working class women were neglectful toward their children. Then key areas such as the working patterns of waged factory mothers will be illustrated to show the agency and determination of 19th century working class women to provide their infants with good care. Reassessment of these historical childcare practices can provide a springboard by which today's health professionals can endeavour to maintain accurate and fair perspectives about the childcare practices of today's women of low socio-economic status.

The Piscina Probatica theme is the highly distinctive iconography in an impressive painted canvas from the ancient Rheims hôtel-Dieu, dating back to the late 15th or early 16th century. In the first place, it is interesting to note that the actual site of the pool has been located, so that archaeological findings bring confirmation to testament scriptures. Through the choice of the painted-canvas medium, and thanks to his great pictorial skill, the anonymous Rheims artist has given us a document of exceptional value, concerning the signs and symptoms of an illness which wrought havoc in the Rheims area in his own lifetime, namely ignis plaga or "mal des ardents". Other great artists of the same period, such as J. Bosch, have testified to the horror of the illness. As a matter-of-fact, the illness has been fully documented, from the 17th century onwards, and the medical expert H.A. Tessier, also acting as an agricultural expert, has demonstrated that ergotized rye is responsible for the fatal condition known as ergotism, and for the heavy toll it has levied on human lives in the course of centuries.

Piasek, Gustav; Piasek, Martina

This overview brings together historical data on health services and health culture from original documents and scarce information published by historians. The seventeenth century Varazdin was a bigger town than Zagreb, and it later even took the title of the Croatian capital from Zagreb (between 1767 and 1776). The review opens with a description of old municipal hospices, specific social and public health institutions which can been traced back to 1454 and which existed throughout the 17th century. At that time, barber-surgeons, who practiced a form of medicine which involved the use of hands and medical instruments (hence the Greek name, heir meaning hand and ergon meaning work), were still active in the town. They did not have the education and skills of a physician (and some physicians were additionally trained as surgeons and/or obstetricians). There were fewer barber-surgeons in the town than in the two previous centuries, and their number was substantially falling in the 17th century. The scale eventually tipped in favour of educated physicians. In 1641, the Croatian Parliament appointed the second official country physician with permanent stay in Varazdin. Other important events are related to the development of pharmacies in the town. The review lists the names of the first pharmacists and the dates of the foundation of pharmacies. The 17th century is characterised by the threat and frequent outbreaks of plague, a disastrous pandemic disease which spread all over Europe and which did not spare Varazdin. It would strike the town at intervals of about every ten years. The authors describe steps taken by the local government to stop the spreading of the disease as well as the incompetence and lack of adequate health measures for both prevention and cure of plague at the time. There are well preserved monuments in memory of those events in the town--a votive chapel and a votive column.

Although recent work has highlighted a host of significant late 20th century environmental changes across the mid to high latitudes of the Southern Hemisphere, the sparse nature of observational records limits our ability to place these changes in the context of long-term (multi-decadal and centennial) variability. As a result, investigating the impact of anthropogenic forcing on climate modes of variability and ecosystems is particularly challenging. Sub-Antarctic islands are particularly important in this regard, straddling major ocean and atmospheric boundaries and offering the potential to develop highly resolved records of change. In 1905, a whaling and meteorological station was established at Grytviken on Sub-Antarctic South Georgia in the South Atlantic (54°S) providing near-continuous observations through to present day. Although South Georgia lies in a strategic location for understanding Southern Ocean atmosphere-ocean dynamics, only a monthly resolved dataset has until now been available. Here we report a near continuous daily observational record from Grytviken for temperature and precipitation, which we compare to different datasets (including Twentieth Century Reanalysis; 20CR version 2c). A warming trend over the 20th century is observed in mean daily temperature at Grytviken with an average rate of temperature rise of 0.14°C per decade over the period 1907-2016 (p<0.0001). We find a significant trend towards increasingly warmer daytime extremes commencing from the mid-20th century accompanied by warmer night-time temperatures. Analysis of these data, and reanalysis products, suggest a realignment of synoptic conditions across the mid to high-latitudes, with a link between increasing temperature trends and atmospheric circulation dominated by stronger westerly airflow, resulting in significant foehn-related warming.

The hydroclimatology of UK droughts: evidence from newly recovered and reconstructed datasets from the late 19th century to present

While the UK is regarded as a wet country, it has periodically suffered from major droughts which have caused serious environmental and societal impacts. Parts of the UK are water stressed and, in a warming world, changes to supply/demand balances could have major implications. There is a pressing need for improved tools for drought risk assessment, which is contingent on a proper understanding of past occurrence of droughts. However, our understanding of hydrological drought occurrence is grounded in the post-1960 period when most UK river flow and groundwater records commenced. As such, water resources planners would benefit from a more thorough assessment of historical drought characteristics and their variability. The multi-disciplinary `Historic Droughts' project thus aims to rigorously characterise droughts in the UK back to the 1890s to inform improved drought management. The foundation of this is a comprehensive characterisation of the hydroclimatology of UK droughts. Here, we present the results of this initiative, based on a hydrological reconstruction campaign of unparalleled scope and detail. Driven by rainfall and potential evapotranspiration data, extended in time using newly recovered observational records, hydro(geo)logical models are used to reconstruct, back to 1890, river flows for >300 catchments across the UK, and groundwater levels from >50 boreholes. The reconstructions are derived within a state-of-the-art modelling framework which allows a comprehensive assessment of uncertainty. A suite of indicators are then applied to these datasets to identify and characterise drought events, integrating precipitation, evapotranspiration, streamflow and groundwater. The work provides new insights into the spatial and temporal dynamics of hitherto poorly quantified late 19th and early 20th century droughts. Similarly, the assessment of temporal variability of drought characteristics benefits from the long timescale of the reconstructions, in turn

The Jewish contribution to medicine. Part I. Biblical and Talmudic times to the end of the 18th century.

Dubovsky, H

1989-07-01

Jewish interest in medicine has a religious motivation with the preservation of health and life as religious commandments in the Holy Scriptures. Despite a basic belief that God caused disease and effected cures with physicians as agents, Jews accepted the rational medicine of ancient Greece. They assisted in the spread of these teachings in the Roman and Arab empires but carried them to the rest of Europe in their migrations. Jews were able to bridge the educational gap of a 500-year period of exclusion from universities and medical schools in the Middle Ages through the Talmud, which started as a commentary on the scriptures in the 5th century BC, but developed over the centuries into a comprehensive body of learning incorporating law, art and the sciences.

Hay fever, a post industrial revolution epidemic: a history of its growth during the 19th century.

PubMed

Emanuel, M B

1988-05-01

Although other forms of allergic disease were described in antiquity, hay fever is surprisingly modern. Very rare descriptions can be traced back to Islamic texts of the 9th century and European texts of the 16th century. It was only in the early 19th century that the disease was carefully described and at that time was regarded as most unusual. By the end of the 19th century it had become commonplace in both Europe and North America. This paper attempts to chart the growth of hay fever through the medical literature of the 19th century. It is hoped that an understanding of the increase in prevalence between 1820 and 1900 may provide an insight for modern researchers and give some clues into possible reasons for the epidemic nature of the disease today.

A Statistical Investigation on a Seismic Transient Occurred in Italy Between the 17th and 20th Centuries

NASA Astrophysics Data System (ADS)

Bragato, P. L.

2017-03-01

According to the historical earthquake catalog of Italy, the country experienced a pulse of seismicity between the 17th century, when the rate of destructive events increased by more than 100%, and the 20th century, characterized by a symmetric decrease. In the present work, I performed a statistical analysis to verify the reliability of such transient, considering different sources of bias and uncertainty, such as completeness and declustering of the catalog, as well as errors on magnitude estimation. I also searched for a confirmation externally to the catalog, analyzing the correlation with the volcanic activity. The similarity is high for the eruptive history of Vesuvius, which agrees on both the main rate changes of the 17th and 20th centuries and on minor variations in the intermediate period. Of general interest, beyond the specific case of Italy, the observed rate changes suggest the existence of large-scale crustal processes taking place within decades and lasting for centuries, responsible for the synchronous activation/deactivation of remote, loosely connected faults in different tectonic domains. Although their origin is still unexplained (I discuss a possible link with the climate changes and the consequent variations of the sea level), their existence and long lasting is critical for seismic hazard computation. In fact, they introduce a hardly predictable time variability that undermines any hypothesis of regularity of the earthquake cycle on individual faults and systems of interconnected faults.

Objectives To see whether a collection of portraits depicting inhabitants of a defined geographical region and covering several centuries is a useful source for studying the sociocultural significance and epidemiology of particular visible diseases, such as goitre, which is known to have been common in this region. Design Systematic review of portraits and description of visible signs of illness. Setting The Burgerbibliothek (archives of the burghers' community) in Berne, Switzerland. Data sources 3615 portraits; 2989 of individuals whose identity is known and 626 of individuals whose identity is unknown. Main outcome measures Visible signs of illness evaluated by means of a standardised visual assessment. Results Visible signs of illness in portraits were common and appeared in up to 82% (451/553) of paintings from the 17th and 18th centuries. The most common findings were signs of goitre in women and overweight in men. In only the portraits where the neck region could be evaluated, 41% of women with known identities (139/343) had goitre compared with 24% of men with known identities (21/86). The prevalence of goitre was even higher in sitters whose identities were unknown: 63% in men (5/8) and 68% in women (82/121). Overweight in people with known identities was more common in men than in women (30%, 346/1145 v 44%, 811/1844). Overweight was most common in sitters aged >40 than in those aged 40 or younger. Other conditions, such as missing teeth, amputated limbs, or osteoarthritic deformations were surprisingly rare in the portraits under evaluation. Conclusions Goitre and other diseases are under-represented in the people depicted in these portraits. Artistic idealisation is a likely explanation for this observation: what was reproduced depended on what was considered pathological or shameful at the time, and therefore depended on age and sex. Stigmatising details may have been omitted. Further, artistic skills and contemporary fashion may have influenced the

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

Georg Friedrich Kordenbusch and astronomy in Nuremberg in the second half of the 18th century. (German Title: Georg Friedrich Kordenbusch und die Astronomie in Nürnberg in der zweiten Hälfte des 18. Jahrhunderts)

NASA Astrophysics Data System (ADS)

Gaab, Hans

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

This study focuses on how human origins were taught in the French Natural Sciences syllabuses of the 19th and 20th centuries. We evaluate the interval between the publication of scientific concepts and their emergence in syllabuses, i.e., didactic transposition delay (DTD), to determine how long it took for scientific findings pertaining to our topic to be introduced in teaching. Conceptions were categorised into four successive periods, each of which lasted approximately half a century. We showed that the DTD on human origins was influenced in each period by the conceptions of the curriculum developers, by the educational system and, more generally, by the socio-political context.

In Mexico, as in the entire Western world, during the 19th century and the beginnings of the 20th century, medical knowledge developed in a remarkable way and the case of diabetes mellitus was not the exception. This situation, which arose on the basis of the antique paradigm, and which in turn was overthrown by the positivism as the emergent paradigm (with its clinical and anatomical, as well as physiopathological and etiopathological viewpoints), was reflected during the 19th the century through its actors and the communications that opened the access of Mexican medicine to the modernity.

This article explains how old, poor people living with dementia came to be institutionalised in 19th-century Britain (with a focus on London), and how they were responded to by the people who ran those institutions. The institutions in question are lunatic asylums, workhouses and charitable homes. Old people with dementia were admitted to lunatic asylums, workhouses and charitable homes, but were not welcome there. Using the records of Hanwell lunatic asylum, published texts of psychiatric theory, and the administrative records that all of these institutions generated at local and national levels, this article argues that 'the senile' were a perpetual classificatory residuum in the bureaucracy of 19th-century health and welfare. They were too weak and unresponsive to adhere to the norms of the asylum regime, yet too challenging in their behaviour to conform to that of the workhouse, or the charitable home. Across all of these institutions, old people with dementia were represented as an intractable burden, many decades before the 'ageing society' became a demographic reality. © 2017 Foundation for the Sociology of Health & Illness.

It was not until the last third of the 19th century, the period in which, according to historiography, the country definitely inserted itself into modernity, that anomalies and monstrosities had a presence in Mexico. Therefore, what I present here are four moments of teratology in Mexico, four dates in which I try to recount how teratology, which still occupied a marginal place within the main themes of national science, not only reached to cover the realm of medical discussions at the time, but also laid the foundations for new disciplines like biology and anthropology.

[Origin of animal experimentation legislation in the 19th century].

Pocard, M

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.

Luís Sousa Silva CITCEM, PhD Fellowship - FCT. João Carlos Garcia CIUHCT, Geography Department, U. of Porto, Portugal. The first major national project on Historical Climatology in Portugal, called "KLIMHIST: Reconstruction and model simulations of past climate in Portugal using documentary and early instrumental sources (17th-19th centuries)", ended in September 2015, coordinated by Maria João Alcoforado. This project began in March 2012 and counted on an interdisciplinary team of researchers from four Portuguese institutions (Centre of Geographical Studies, University of Trás-os-Montes and Alto Douro, University of Porto, and University of Évora), from different fields of knowledge (Geography, History, Biology, Climatology and Meteorology). The team networked and collaborated with other international research groups on Climate Change and Historical Climatology, resulting in several publications. This project aimed to reconstruct thermal and rainfall patterns in Portugal between the 17th and 19th centuries, as well as identify the main hydrometeorological extremes that occurred over that period. The basic methodology consisted in combining information from different types of anthropogenic sources (descriptive and instrumental) and natural sources (tree rings and geothermal holes), so as to develop climate change models of the past. The data collected were stored in a digital database, which can be searched by source, date, location and type of event. This database, which will be made publically available soon, contains about 3500 weather/climate-related records, which have begun to be studied, processed and published. Following this seminal project, other initiatives have taken place in Portugal in the area of Historical Climatology, namely a Ph

Tribal distributions depicted on these maps (and on all other tribal maps covering a comparable area) are arbitrary at many points. Detailed knowledge of tribal areas was acquired at different times in different regions. For example, by the time knowledge was gained of the areas occupied by Plains tribes, many groups in the East had become extinct or had moved from their aboriginal locations. Some of these movements ultimately affected distributions on the Plains prior to reasonably detailed knowledge of Plains occupancy. Hence, it is not possible to approximate aboriginal areas of occupancy on a single map of continental scope. Furthermore, most groups did not occupy sharply defined areas, so that the delineation of territories is misleading.Distributions were derived, with slight modifications, from Indian tribes of North America (Driver and others, 1953), and boundaries within California were simplified after Languages, territories, and names of California Indian tribes (Heizer, 1966). According to the authors of these publications, the boundaries shown are those of the mid-17th century in the Southeast and the eastern part of the Northeast, the late 17th and early 18th centuries farther west in the Northeast, the late 18th and early 19th centuries in the Plains, the late 18th century in California, and the middle-to-late 19th century elsewhere. Even so, many compromises had to be made.

2003-07-01

The prospect of traveling to the planets was science fiction at the beginning of the 20th Century and science fact at its end. The space age was born of the Cold War in the 1950s and throughout most of the remainder of the century it provided not just an adventure in the exploration of space but a suspenseful drama as the US and USSR competed to be first and best. It is a tale of patience to overcome obstacles, courage to try the previously impossible and persistence to overcome failure, a tale of both fantastic accomplishment and debilitating loss. We briefly describe the history of robotic lunar and planetary exploration in the 20th Century, the missions attempted, their goals and their fate. We describe how this enterprise developed and evolved step by step from a politically driven competition to intense scientific investigations and international cooperation.

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

The paper deals with the development of the first editions of the Austrian Pharmacopoeia, Pharmacopoea Austriaca, since its origin in the year 1812. It demonstrates its gradual retardation in the period when nearly all medicinal substances had to be prepared only in pharmacies. The conception was changed as late as 1855 in the Fifth Edition, when it was allowed to buy many medicinal substances from producers or wholesalers. At the same time, requirements for organoleptic properties and chemical purity began to be introduced. The present communication also deals with the chemical drugs used in the mid-19th century and is based on a comparison of the pharmacopoeias of 1836 and 1855. It presents some typical examples, such as alkaloids and metal compounds.

The 20th century has been one of the most intense and convulsive periods in the History of humanity. A century of paradoxes and contrasts, it began with optimism, it witnessed the apocalypse of two world wars, and finished with unimaginable scientific progress that gave us a new civilization that we cannot yet grasp. In this century, significant events happened that shaped our time and projected their results toward an immediate future. Some of these were providential in understanding man's life, fighting against illnesses and prolonging life, and others were of undeniable social importance for humanity. Some knowledge was based on the work of others. Philosophy was embedded in mathematics, as was science in philosophy, while politics and the economy exercised so decisive an influence in our way of feeling and living that culture and society were affected to the core. Within that century the biggest technological revolution of all the time was also created, as transcendent as it was unimaginable, which put mankind on the road to the stars with the moon landing and in the process created the information society whose signature symbol, the internet, emerged as a new demiurge. However, the 20th century, with all its misfortune and splendor, paradoxes and contrasts, creation and destruction, was the most transcendent in the whole of history and it bequeaths to the future a promising horizon in the search for a renovated meaning of life and a yearning for peaceful coexistence for the whole humanity.

Health in Barbados in the 20th century.

Walrond, E R

2001-09-01

At the beginning of the 20th century, Barbados was described as the most unhealthy place in the British Empire; at the end of the century, it is considered amongst the healthiest of developing countries. At the start of the century the statistics were harsh; for example, there was an infant mortality rate of 400 per 1000 live births. It is now between 10 and 15 per 1000 live births. In the last two-thirds of the century, there was a series of ongoing revolutions in Education, Public Health and Hospital Services that affected the health status favourably. The revolution in education was enhanced by the provision of University education starting with Medicine at Mona, Jamaica. Training of doctors expanded to Barbados in 1967 and has been an essential ingredient in the medical care revolution of the last third of the century. In 1953, the first Public Health Centre was opened and Barbados can now boast the most modern public health and primary care facilities. However, modern lifestyles are associated with an epidemic of obesity, diabetes mellitus and hypertension. HIV/AIDS has emerged as a major problem. Health in the 21st century will need to look at lifestyles--the effects of the internal combustion engine, the availability of tools of violence, the lure of 'illegal drugs', personal relationships and gender as well as the driving forces behind the associated lifestyles.

This study reconstructs a series of droughts and high flow volumes of the Bermejo River from the 17th to 20th century based on a content analysis of historic documentary evidence, which is calibrated with instrumental climate data. The historic data series shows an increase in the frequency of extraordinarily high waters beginning in the 19th century and a significant decrease in extreme droughts beginning in 1890. The data are compared to variations in the Mendoza River for the same period, which show that there was a long-standing lack of correlation between the rivers.

MECHANICS OF THE LUNG IN THE 20TH CENTURY

PubMed Central

Mitzner, Wayne

2015-01-01

Major advances in respiratory mechanics occurred primarily in the latter half of the 20th century, and this is when much of our current understanding was secured. The earliest and ancient investigations involving respiratory physiology and mechanics were often done in conjunction with other scientific activities and often lacked the ability to make quantitative measurements. This situation changed rapidly in the 20th century, and this relatively recent history of lung mechanics has been greatly influenced by critical technological advances and applications, which have made quantitative experimental testing of ideas possible. From the spirometer of Hutchinson, to the pneumotachograph of Fleisch, to the measurement of esophageal pressure, to the use of the Wilhelmy balance by Clements, to the unassuming strain gauges for measuring pressure and rapid paper and electronic chart recorders, these enabling devices have generated numerous quantitative experimental studies with greatly increased physiologic understanding and validation of mechanistic theories of lung function in health and disease.

The risk of dying from gastric cancer appears to have increased among consecutive generations born during the 19th century. To follow the time trends of hospitalization for gastric cancer and test whether they confirm such increase. Inpatient records of the last two centuries from four hospitals in Scotland and three US hospitals were analysed. Proportional rates of hospitalization for gastric cancer, gastric ulcer and duodenal ulcer were calculated during consecutive 5-year periods. The data from all seven cities revealed strikingly similar patterns. No hospital admissions for gastric cancer or peptic ulcer were recorded prior to 1800. Hospital admissions for gastric cancer increased in an exponential fashion throughout the 19th and the beginning of the 20th century. In a majority of cities, the rise in hospitalization for gastric cancer preceded a similar rise in hospitalization for gastric ulcer. Hospitalization for these two latter diagnoses clearly preceded hospitalization for duodenal ulcer by 20-40 years. The occurrence of gastric cancer, gastric ulcer and duodenal ulcer markedly increased during the 19th century. Improvements in hygiene may have resulted in the decline of infections by other gastrointestinal organisms that had previously kept concomitant infection by Helicobacter pylori suppressed.

Anthropogenic sulfate aerosol and the southward shift of tropical precipitation in the late 20th century

NASA Astrophysics Data System (ADS)

Hwang, Yen-Ting; Frierson, Dargan M. W.; Kang, Sarah M.

2013-06-01

In this paper, we demonstrate a global scale southward shift of the tropical rain belt during the latter half of the 20th century in observations and global climate models (GCMs). In rain gauge data, the southward shift maximizes in the 1980s and is associated with signals in Africa, Asia, and South America. A southward shift exists at a similar time in nearly all CMIP3 and CMIP5 historical simulations, and occurs on both land and ocean, although in most models the shifts are significantly less than in observations. Utilizing a theoretical framework based on atmospheric energetics, we perform an attribution of the zonal mean southward shift of precipitation across a large suite of CMIP3 and CMIP5 GCMs. Our results suggest that anthropogenic aerosol cooling of the Northern Hemisphere is the primary cause of the consistent southward shift across GCMs, although other processes affecting the atmospheric energy budget also contribute to the model-to-model spread.

Transcription factor-dependent chromatin remodeling of Il18r1 during Th1 and Th2 differentiation 1

2008-01-01

The IL-18Rα chain is expressed on Th1 but not Th2 cells. We have recently shown that Stat4 is an important component of programming the Il18r1 locus (encoding IL-18Rα) for maximal expression in Th1 cells. Il18r1 is reciprocally repressed during Th2 development. In this report we demonstrate that the establishment of DNase hypersensitivity patterns that are distinct among undifferentiated CD4 T cells, Th1 and Th2 cells. Stat6 is required for the repression of Il18r1 expression and in Stat6-deficient Th2 cultures, mRNA levels, histone acetylation and H3K4 methylation levels are intermediate between levels observed in Th1 and Th2 cells. Despite the repressive effects of IL-4 during Th2 differentiation, we observed only modest binding of Stat6 to the Il18r1 locus. In contrast, we observed robust GATA-3 binding to a central region of the locus where DNase hypersensitivity sites overlapped with conserved non-coding sequences in Il18r1 introns. Ectopic expression of GATA-3 in differentiated Th1 cells repressed Il18r1 mRNA and surface expression of IL-18Rα. These data provide further mechanistic insight into transcription factor dependent establishment of Th subset-specific patterns of gene expression. PMID:18714006

This article analyses the struggles of 19th century Mexican physicians to gain professional autonomy versus the state. Medical practitioners sought to resist the imposition of a series of state measures, including directives to attend all patients and provide free care to the poor, forced adherence to political ideologies, state control of medical education, penal action in cases of professional liability, violation of medical confidentiality, and challenges to professional freedom. The article shows the reach of political power over medical practice in the 19th century, and explains the range and limits of the power of the medical profession.

Naming and Necessity: Sherborn’s Context in the 19th Century

2016-01-01

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

Floods of the Lower Tisza from the late 17th century onwards: frequency, magnitude, seasonality and great flood events

2016-04-01

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

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

NASA Astrophysics Data System (ADS)

Sullivan, Woodruff T.

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

Polar lows in the Labrador Sea based on the Moravian historical collection of meteorological data in Labrador and Greenland since the mid-18th century

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

Endless cold: a seasonal reconstruction of temperature and precipitation in the Burgundian Low Countries during the 15th century based on documentary evidence

NASA Astrophysics Data System (ADS)

Camenisch, C.

2015-08-01

This paper applies the methods of historical climatology to present a climate reconstruction for the area of the Burgundian Low Countries during the 15th century. The results are based on documentary evidence that has been handled very carefully, especially with regard to the distinction between contemporary and non-contemporary sources. Approximately 3000 written records derived from about 100 different sources were examined and converted into seasonal seven-degree indices for temperature and precipitation. For the Late Middle Ages only a few climate reconstructions exist. There are even fewer reconstructions which include spring and autumn temperature or any precipitation information at all. This paper therefore constitutes a useful contribution to the understanding of climate and weather conditions in the less well researched but highly interesting 15th century. The extremely cold winter temperatures during the 1430s and an extremely cold winter in 1407/1408 are striking. Moreover, no other year in this century was as hot and dry as 1473. At the beginning and the end of the 1480s and at the beginning of the 1490s summers were considerably wetter than average.

Relevance of 19th century continuous tone photomechanical printing techniques to digitally generated imagery

NASA Astrophysics Data System (ADS)

Hoskins, Stephen; Thirkell, Paul

2003-01-01

Collotype and Woodburytype are late 19th early 20th century continuous tone methods of reproducing photography in print, which do not have an underlying dot structure. The aesthetic and tactile qualities produced by these methods at their best, have never been surpassed. Woodburytype is the only photomechanical print process using a printing matrix and ink, that is capable of rendering true continuous tone; it also has the characteristic of rendering a photographic image by mapping a three-dimensional surface topography. Collotype"s absence of an underlying dot structure enables an image to be printed in as many colours as desired without creating any form of interference structure. Research at the Centre for Fine Print Research, UWE Bristol aims to recreate these processes for artists and photographers and assess their potential to create a digitally generated image printed in full colour and continuous tone that will not fade or deteriorate. Through this research the Centre seeks to provide a context in which the development of current four-colour CMYK printing may be viewed as an expedient rather than a logical route for the development of colour printing within the framework of digitally generated hard copy paper output.

Early 20th-century Arctic warming intensified by Pacific and Atlantic multidecadal variability

2017-01-01

With amplified warming and record sea ice loss, the Arctic is the canary of global warming. The historical Arctic warming is poorly understood, limiting our confidence in model projections. Specifically, Arctic surface air temperature increased rapidly over the early 20th century, at rates comparable to those of recent decades despite much weaker greenhouse gas forcing. Here, we show that the concurrent phase shift of Pacific and Atlantic interdecadal variability modes is the major driver for the rapid early 20th-century Arctic warming. Atmospheric model simulations successfully reproduce the early Arctic warming when the interdecadal variability of sea surface temperature (SST) is properly prescribed. The early 20th-century Arctic warming is associated with positive SST anomalies over the tropical and North Atlantic and a Pacific SST pattern reminiscent of the positive phase of the Pacific decadal oscillation. Atmospheric circulation changes are important for the early 20th-century Arctic warming. The equatorial Pacific warming deepens the Aleutian low, advecting warm air into the North American Arctic. The extratropical North Atlantic and North Pacific SST warming strengthens surface westerly winds over northern Eurasia, intensifying the warming there. Coupled ocean–atmosphere simulations support the constructive intensification of Arctic warming by a concurrent, negative-to-positive phase shift of the Pacific and Atlantic interdecadal modes. Our results aid attributing the historical Arctic warming and thereby constrain the amplified warming projected for this important region. PMID:28559341

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.

Chinese historical documents are an extremely useful source from which much climate information can be retrieved if treated carefully. This is especially relevant to the reconstruction of climate in East Asia in the last 2000 years as the Chinese has kept official chronicles since 500BC and China also represents a large portion of East Asia's land. In addition, there are also local records in many cities and counties. When available, such documentary sources are often superior to environmental proxy data, especially in the time resolution as they usually provide at least annual resolution and even as high as daily records in some cases. This research will report on our recent advances on using a new REACHS dataset that collects primarily documented meteorological records from thousands of imperial and local chronicles in the Chinese history for more than 2000 years. The meteorological records were digitized and coded in the relational database management system in which accurate time (from yearly to daily), space (from province to city/county) and event (from meteorological to phonological and social) information is carefully reserved for analysis. We then formed digital climate series and performed time series and spatial analysis on them to obtain their temporal and spatial characteristics. Our present research results on the annual and seasonal temperature reconstruction during 17th-19th indicates lower temperature in the 17th century. There were also strangely high occurrence frequency of summer snowfall records in the lower reaches of Yangtze River during the Maunder Minimum. Reconstructed precipitation series fluctuated with strong regional character in the Northeast, Central-east and Southeast China. Spectral analysis shows that precipitation series have significant periodicity of 3-5 and 8-12 years during the period, suggesting strong interannual variability and different regional signatures. Flood happened frequently but long lasting drought was more

[Traces of blood. The significance of blood in criminology at the turn of the 19th century].

Bachhiesl, Christian

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.

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 study of anatomy in England during the 18th and 19th century has become infamous for bodysnatching from graveyards to provide a sufficient supply of cadavers. However, recent discoveries have improved our understanding of how and why anatomy was studied during the enlightenment, and allow us to see the context in which dissection of the human body took place. Excavations of infirmary burial grounds and medical school cemeteries, study of hospital archives, and analysis of the content of surviving anatomical collections in medical museums enables us to re-evaluate the field from a fresh perspective. The pathway from a death in poverty, sale of the corpse to body dealer, dissection by anatomist or medical student, and either the disposal and burial of the remains or preservation of teaching specimens that survive today in medical museums is a complex and fascinating one.

In 17th century France, the practice of obstetrics passed from female midwives to medical men called accoucheurs. François Mauriceau, a prominent French obstetrician of the 17th century urged the need of an organised obstetrical education, emphasising anatomy. He invented the semi-recumbent or 'French' birthing position, the 'tire-tête' forceps, the 'Mauriceau manoeuvre' in breech delivery, and provided one of the first epidemiological analyses in obstetrics contributing enormously to the development of this specialty. His best-seller, Traité des maladies des femmes grosses revolutionised the practice of obstetrics.

Until the mid-19th century, there had not been a single resident physician in the Holy Land. However, by the first World War in 1914, 19 hospitals had been established in Jerusalem. The reasons for this unusual phenomenon were religious, political, and sectarian. This does not apply to The Marienstift Kinderhospital, which was unique in 19th century Jerusalem. The hospital was founded and operated by Dr Max Sandreczky, a German pediatric surgeon. The standards of medical and surgical practice in the hospital not only compared favorably with those in western Europe, but, in certain aspects, they were more advanced. The Marienstift Kinderhospital was an "implant" of a western institution in a society that was medieval in character. The response of this society was studied as well as the natural history of this unique institution and its medical director, the pediatric surgeon, Dr Max Sandreczky.

The ancient Hungarians originated from the Ural region in today’s central Russia and migrated across the Eastern European steppe, according to historical sources. The Hungarians conquered the Carpathian Basin 895–907 AD, and admixed with the indigenous communities. Here we present mitochondrial DNA results from three datasets: one from the Avar period (7th–9th centuries) of the Carpathian Basin (n = 31); one from the Hungarian conquest-period (n = 76); and a completion of the published 10th–12th century Hungarian-Slavic contact zone dataset by four samples. We compare these mitochondrial DNA hypervariable segment sequences and haplogroup results with published ancient and modern Eurasian data. Whereas the analyzed Avars represents a certain group of the Avar society that shows East and South European genetic characteristics, the Hungarian conquerors’ maternal gene pool is a mixture of West Eurasian and Central and North Eurasian elements. Comprehensively analyzing the results, both the linguistically recorded Finno-Ugric roots and historically documented Turkic and Central Asian influxes had possible genetic imprints in the conquerors’ genetic composition. Our data allows a complex series of historic and population genetic events before the formation of the medieval population of the Carpathian Basin, and the maternal genetic continuity between 10th–12th century and modern Hungarians.

2012-01-01

THE STRUCTURE, FUNCTION(S) and symbolism of early medieval (9th–10th centuries ad) fortified settlements from central Europe, in particular today’s Austria, Hungary, Czech Republic and Slovakia, are examined in this paper. It offers an overview of the current state of research together with new insights based on analysis of the site of Gars-Thunau in Lower Austria. Special emphasis is given to the position of the fortified sites in the landscape, to the elements of the built environment and their spatial organisation, as well as to graves within the fortified area. The region under study was situated on the SE border of the Carolingian (and later the Ottonian) Empire, with some of the discussed sites lying in the territory of the ‘Great Moravian Empire’ in the 9th and 10th centuries. These sites can therefore provide important comparative data for researchers working in other parts of the Carolingian Empire and neighbouring regions. PMID:23564981

The role of vertical land movements on late 19th century sea level rise at Cuxhaven, Germany

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).

Ancient mtDNA Analysis of Early 16th Century Caribbean Cattle Provides Insight into Founding Populations of New World Creole Cattle Breeds

The Columbian Exchange resulted in a widespread movement of humans, plants and animals between the Old and New Worlds. The late 15th to early 16th century transfer of cattle from the Iberian Peninsula and Canary Islands to the Caribbean laid the foundation for the development of American creole cattle (Bos taurus) breeds. Genetic analyses of modern cattle from the Americas reveal a mixed ancestry of European, African and Indian origins. Recent debate in the genetic literature centers on the ‘African’ haplogroup T1 and its subhaplogroups, alternatively tying their origins to the initial Spanish herds, and/or from subsequent movements of taurine cattle through the African slave trade. We examine this problem through ancient DNA analysis of early 16th century cattle bone from Sevilla la Nueva, the first Spanish colony in Jamaica. In spite of poor DNA preservation, both T3 and T1 haplogroups were identified in the cattle remains, confirming the presence of T1 in the earliest Spanish herds. The absence, however, of “African-derived American” haplotypes (AA/T1c1a1) in the Sevilla la Nueva sample, leaves open the origins of this sub-haplogroup in contemporary Caribbean cattle.

PubMed

Sihn, Kyu Hwan

2012-04-30

This paper aimed to examine the anatomical revolution from Yilingaicuo (Correcting the Errors of Medicine) and Quantixinlun(Outline of Anatomy and Physiology) in late imperial China. As the cephalocentrism which the brain superintend human operation of the mind was diffused in China since 16th century, the cephalocentrism and the cardiocentrism had competed for the hegemony of anatomical conception. Because of the advent of Yilingaicuo and Quantixinlun, the cephalocentrism became the main stream in the anatomical conception. The supporters of the Wang Yangming's Xinxue(the Learning of Heart and Mind) argued that the heart was the central organ of perception, sensitivity, and morality of the human body in medicine since 16th century. Even reformist and revolutionary intellectuals like Tan sitong and Mao zedong who had supported the Wang Yangming's Xinxue embraced the cephalocentrism in the late 19th century and the early 20th century. May Fourth intellectuals had not obsessed metaphysical interpretation of human body any more in the New Culture Movement in 1910s. They regarded human body as the object of research and writing. The anatomy was transformed into the instrumental knowledge for mutilation of the body. Yilingaicuo challenged the traditional conception of body, and Chinese intellectuals drew interest in the anatomy knowledge based on real mutilation. Quantixinlun based on Western medicine fueled a controversy about anatomy. Though new knowledge of anatomy was criticized by traditional Chinese medical doctors from the usefulness and morality of anatomy, nobody disavowed new knowledge of anatomy from the institutionalization of Western medicine in medical school. The internal development of cephalocentrism and positivism had influence on anatomy in China since 16th century. The advent of Yilingaicuo and Quantixinlun provided the milestone of new anatomy, though both sides represented traditional Chinese medicine and Western medicine respectively. They

A brief history of the changing occupations and demographics of coleopterists from the 18th through the 20th century.

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

The medieval discipline of the ars dictaminis (or dictamen), which flourished during the 12(th)-14(th) centuries, can be considered as an adaptation of classical Latin rhetoric to the communicational needs of the medieval society. Yet, although the relation between the teaching of the ars and its practice is an important one, it has rarely been addressed because of the persistence of numerous misunderstandings about the various different levels at which the ars was taught.

The 6(th) archaeological excavation campaign performed at the 'Pieve di Pava' (San Giovanni d'Asso, Siena, Italy) unearthed a privileged stone burial of a single individual (US 2378), covered by a monolithic slab and placed in front of an altar. The skeletal remains of a young male (18-20 years old), not in anatomical connection, were found at the bottom floor of a tomb (160 cm long, 40 cm large and over 70 cm deep). A multidisciplinary study has been carried out concerning that privileged bone burial. The study combines paleopathology studies, stable isotope palaeodietary reconstruction, radiocarbon dating and archaeological analyses. (14)  C dating of the skeleton revealed a date between 650 and 688 AD. Stable isotope analysis (δ(18) O, δ(13) C, δ(15) N) attested that he was probably a member of the local population, whose diet was rather rich in animal proteins. The paleopathological study diagnosed a case of acromesomelic dysplasia, a congenital anomaly with disproportion of the limbs. Archaeological evidence regarding the circular delimitation of the bones suggested that the skeleton was a secondary deposition, transported to the church in a sack. We argue that the relic was used for the re-consecration of the church, following the restoration work in the 8(th) century. We conclude that the skeleton belonged to an eminent personage (e.g., either the member of a local elite family or a saint). Copyright © 2012 John Wiley & Sons, Ltd.

Two sherds representative of the Portuguese faience production of the first and second halves of the 17th century were studied carefully with the use of non-invasive spectroscopies, namely: Ground State Diffuse Reflectance Absorption (GSDR), micro-Raman, Fourier-Transform Infrared (FT-IR), Laser Induced Luminescence (LIL) and Proton Induced X-ray (PIXE). These results were compared with the ones obtained for a Chinese Ming porcelain, Wanli period (16th/beginning of the 17th centuries), which served as an influence for the initial Lisbon's faience production. By combining information of the different non-destructive spectroscopic techniques used in this work, it was possible to conclude that: Co3O4 (Co II and Co III) can be found in the silicate matrix and is the blue pigment in the "Especieiro" sample (1st half of the 17th C.). Cobalt olivine silicate (Co2SiO4, Co II only) was clearly identified as the blue pigment in "Aranhões" sample (2nd half of the17th C.) - 824 cm-1 band in the micro-Raman-spectrum. Cobalt aluminate (CoAl2O4, Co II only) is the blue pigment in the Wanli plate - 203 and 512 cm-1 bands in the micro-Raman spectrum. The blue pigment in the 1st half 17th century of Lisbon's production was obtained by addition of a cobalt ore in low concentrations, which gives no specific Raman signature, because of complete dissolution in the glass. However, in most cases of the 2nd half 17th century, the Raman signature was quite evident, from a cobalt silicate. These findings point to the use of higher temperature kilns in the second case.

Large families of apothecaries, some of them very famous, lived in the Quartier de la Harpe in Paris, on the left bank of Seine, from the 16th to the 17th century. The study confirms a well-established fact that apothecaries practised endogamy, in others words marriage within the same social class. The biographical research includes ten apothecaries, most of whom lived in the rue Saint-André-des-Arts.

Global economic impacts of climate variability and change during the 20th century.

Estimates of the global economic impacts of observed climate change during the 20th century obtained by applying five impact functions of different integrated assessment models (IAMs) are separated into their main natural and anthropogenic components. The estimates of the costs that can be attributed to natural variability factors and to the anthropogenic intervention with the climate system in general tend to show that: 1) during the first half of the century, the amplitude of the impacts associated with natural variability is considerably larger than that produced by anthropogenic factors and the effects of natural variability fluctuated between being negative and positive. These non-monotonic impacts are mostly determined by the low-frequency variability and the persistence of the climate system; 2) IAMs do not agree on the sign (nor on the magnitude) of the impacts of anthropogenic forcing but indicate that they steadily grew over the first part of the century, rapidly accelerated since the mid 1970's, and decelerated during the first decade of the 21st century. This deceleration is accentuated by the existence of interaction effects between natural variability and natural and anthropogenic forcing. The economic impacts of anthropogenic forcing range in the tenths of percentage of the world GDP by the end of the 20th century; 3) the impacts of natural forcing are about one order of magnitude lower than those associated with anthropogenic forcing and are dominated by the solar forcing; 4) the interaction effects between natural and anthropogenic factors can importantly modulate how impacts actually occur, at least for moderate increases in external forcing. Human activities became dominant drivers of the estimated economic impacts at the end of the 20th century, producing larger impacts than those of low-frequency natural variability. Some of the uses and limitations of IAMs are discussed.

Faces and Photography in 19th-Century Visual Science.

PubMed

Wade, Nicholas J

2016-09-01

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 Author(s) 2016.

[The living conditions of Jewish physicians in Frankfort on Main in the late Middle Ages and Early Modern Times].

PubMed

Treue, W

1998-01-01

During almost the entire period covered in this article (ca. 1345-1745), the living conditions of Jewish physicians in the Free Imperial City of Frankfort on Main depended to a large extent on the attitudes of the Town Council. The Council, with its increasingly absolutist conception of government, supervised Jewish doctors very closely; on the other hand, it also protected them against the recurrent attacks of Christian physicians, pharmacists and clergymen. The Council understood the importance of the Jewish community to the city's economy, and the contribution of Jewish physicians to the welfare of the city and the neighboring principalities. Until the late 15th century, Jewish medical students were not admitted to European universities; the unique exception was Padua. Hence, arguments against Jewish physicians revolved around their lack of academic qualifications. Such claims were weakened at the end of the 16th century, when the first Jewish graduates from Padua University arrived in Frankfort. The opening of Western European universities in the 17th and 18th centuries enabled increasing numbers of Jews to obtain academic training. The medical profession had become a tradition in many Jewish families, beginning in the Middle Ages; and this tradition was now reinforced and complemented by academic credentials.

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

PubMed

Kawashima, Keiko

2011-01-01

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

Physics students at Worcester State University visit the Worcester Art Museum (WAM) at the end of a special 100-level course called Physics in Art. The students have studied geometrical optics, and they have been introduced to concepts in atomic physics. The purpose of the museum tour is to show how physics-based techniques can be used in a nontraditional lab setting. Other examples of the use of museum-based art in physics instruction include analyses of Pointillism and image resolution, and of reflections in soap bubbles in 17- and 18th-century paintings.

Forming, transfer and globalization of medical-pharmaceutical knowledge in South East Asian missions (17th to 18th c.) - historical dimensions and modern perspectives.

2015-06-05

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

Observation-Driven Estimation of the Spatial Variability of 20th Century Sea Level Rise

Over the past two decades, sea level measurements made by satellites have given clear indications of both global and regional sea level rise. Numerous studies have sought to leverage the modern satellite record and available historic sea level data provided by tide gauges to estimate past sea level rise, leading to several estimates for the 20th century trend in global mean sea level in the range between 1 and 2 mm/yr. On regional scales, few attempts have been made to estimate trends over the same time period. This is due largely to the inhomogeneity and quality of the tide gauge network through the 20th century, which render commonly used reconstruction techniques inadequate. Here, a new approach is adopted, integrating data from a select set of tide gauges with prior estimates of spatial structure based on historical sea level forcing information from the major contributing processes over the past century. The resulting map of 20th century regional sea level rise is optimized to agree with the tide gauge-measured trends, and provides an indication of the likely contributions of different sources to regional patterns. Of equal importance, this study demonstrates the sensitivities of this regional trend map to current knowledge and uncertainty of the contributing processes.

Windstorms play an important role in weather variability over western Europe. Strong winds associated with fronts and sting jets can lead to several social and economic damages. However, in addition to wind intensity, the displacement speed of the storm, its area and position are also important factors in determining loss. In this study we focus on windstorms associated with the highest damages of the 20th century, and we analyse whether the dynamical structure of the storm is related to its impact. First, we apply an extra-tropical storm tracking algorithm to the ECMWF ERA-20C reanalysis that covers the whole twentieth century and for the whole Northern Hemisphere. Secondly, using the same data, we compute the 3-hourly Loss and Meteorological index for 18 different European countries as in Pinto et al. (2012) with a 25km grid resolution. Thirdly, we develop a High-Loss Tracking Method that matches information from the Loss Index results and the trajectories tracked to systematically associate damages over a particular country to a particular storm. Such a combination provides information on the typical life cycle of storms that create strong damages over a particular country. Finally, only storms hitting France are considered. More than 1500 storms are detected over the whole period and their evolution is analyzed by performing various composites depending on their position relative to the jet stream and their region of impact.

The impact of childhood sickness on adult socioeconomic outcomes: Evidence from late 19th century America

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

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.

Concurrent phenomena of science and history in the 17th century and their essential interdependence.

Bloch, H.

The explanation for the explosion of science in the 17th century lies in history and medical historiography. Without this approach, it becomes fantasy, accidents, or success stories. Sigerist grasped the essential interdependence of science and history, and had no need for devised reasons or speculation. He realized that once the dark night of the Middle Ages was over, the sciences arose with undreamt of force and accelerated development. The advances in astronomy, mathematics, mechanics, and experimental science benefitted a society developing in seafaring, manufacture, and trade in the 17th century. Sigerist's views make the scientific explosion understandable in human and social terms. He did not overlook the capabilities of some extraordinary individuals, such as Paracelsus (1493-1541), to shape the course of medicine, nor the importance of the mechanistic philosophy in the 17th century. Man makes history and science; hence, we find concurrent phenomena of history and science essentially interdependent. The spirit of experimental science of 17th century England was inspired by the new needs of commercial enterprise for more means of transportation and communication. Likewise, the interest in the mechanics of the pump for waterworks and for the drainage of swamps led Harvey to think of the heart as a pump, and to explain the circulation of the blood in terms of its functioning.

The beginning of metallurgy in the ancient Near East attracts much attention. The southern Levant, with the rich assemblage of copper artifacts from the Nahal Mishmar cave and the unique gold rings of the Nahal Qanah cave, is regarded as a main center of early metallurgy during the second half of the 5th millennium CalBC. However, a recently discovered copper awl from a Middle Chalcolithic burial at Tel Tsaf, Jordan Valley, Israel, suggests that cast metal technology was introduced to the region as early as the late 6th millennium CalBC. This paper examines the chemical composition of this item and reviews its context. The results indicate that it was exported from a distant source, probably in the Caucasus, and that the location where it was found is indicative of the social status of the buried individual. This rare finding indicates that metallurgy was first diffused [corrected] to the southern Levant through exchange networks and only centuries later involved local productionThis copper awl, the earliest metal artifact found in the southern Levant, indicates that the elaborate Late Chalcolithic metallurgy developed from a more ancient tradition.

We investigate the potential impact of climate change on water availability in central Belgium. Two water balance components being precipitation and potential evapotranspiration are initially projected for the late 21st century (2071-2100) based on 30 Coupled Models Intercomparison Project phase 5 (CMIP5) models relative to a baseline period of 1961-1990, assuming forcing by four representative concentration pathway emission scenarios (RCP2.6, RCP4.5, RCP6.0, RCP8.5). The future available water is then estimated as the difference between precipitation and potential evapotranspiration projections. The number of wet days and mean monthly precipitation for summer season is projected to decrease in most of the scenarios, while the projections show an increase in those variables for the winter months. Potential evapotranspiration is expected to increase during both winter and summer seasons. The results show a decrease in water availability for summer and an increase for winter, suggesting drier summers and wetter winters for the late 21st century in central Belgium.

Placebos in 19th century medicine: a quantitative analysis of the BMJ.

PubMed

Raicek, Jacqueline E; Stone, Bradley H; Kaptchuk, Ted J

2012-12-18

To provide the first quantitative data on the use of the term "placebo" in the 19th century. Computer search of BMJ's archival database from January 1840 (the first issue) through December 1899 for uses of the words "placebo(s)." Grounded theory was used to categorise the implications of uses of the term. 71 citations contained the term "placebo(s)." Of these, 22 (31%) used the term to mean "no effect" or as a general pejorative term, 18 (25%) portrayed placebo treatment as permitting the unfolding of the natural history (the normal waxing and waning of illness), 14 (20%) described placebo as important to satisfy patients, 7 (10%) described it as fulfilling a physician's performance role, 3 (4%) described its use to buy time, 3 (4%) described its use for financial gain, 2 (3%) used it in a manner similar to a placebo control, and only one implied that placebo could have a clinical effect. Only one citation mentioned telling the patient about his placebo treatment. Nineteenth century physicians had diverse a priori assumptions about placebos. These findings remind us that contemporary medicine needs to use rigorous science to separate fact from its own beliefs concerning the "provision of care." As in previous generations, ethical issues concerning placebos continue to challenge medicine.

Alfred Werner's role in the mid-20th century flourishing of American inorganic chemistry.

Labinger, Jay A

2014-01-01

The development of organic and physical chemistry as specialist fields, during the middle and end of the 19th century respectively, left inorganic behind as a decidedly less highly regarded subfield of chemistry. Despite Alfred Werner's groundbreaking studies of coordination chemistry in the early 20th century, that inferior status remained in place - particularly in the US - until the 1950s, when the beginnings of a resurgence that eventually restored its parity with the other subfields can be clearly observed. This paper explores the extent to which Werner's heritage - both direct, in the form of academic descendants, and indirect - contributed to those advances.

The first intuitions and descriptions of anesthesia can be found in the antique civilizations. In the 19th century, the invention of anesthesia took place in Boston, and quickly spread to Europe. In France, regulations and structures were created before the beginning of the 20th century to organize this new profession, for children as well as for adults.

Secular trends of increasing weight and height over past centuries are well documented in developed countries. However, these data are still scarce in developing countries such as Brazil. To verify the secular trends of height, weight and body mass index (BMI) of military students from Brazilian Army schools who were born between the 1920s and 1990s. A retrospective study was performed, which included a survey of data from the files of two Army schools. The sample was composed of subjects aged between 18-20 years old. The study analysed 2169 heights and 1741 weights and BMIs. During the evaluation period, height increased 7.3 cm, weight 9.8 kg and BMI 1.8 kg/m(2). The most significant gains were observed in subjects born from the 1920s to the 1940s and the 1960s to the 1970s. Secular trends of growth in military students born in the 20th century were positive in Brazil, although increases were not constant decade-by-decade.

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

The «New Map of Rome» by Giambattista Nolli: a precise representation of the urban space in the 18th century

2010-05-01

The paper refers to the on going experience of the project "The Historic Atlas of Modern Rome" implemented by CROMA (Centro di ateneo per lo studio di Roma) - University Roma Tre. The project combines research in urban history with geographical information systems, and has as main objective to study the "historic environment" of Rome and its transformations. In 1748, Giovanni Battista Nolli (1692-1756) published his «New Map of Rome» (Nuova Pianta di Roma). This work represents the first geometrically correct representation of Rome within the city walls, and the only map deriving from a topographical survey of which the procedures are known. The map represents a precious source of information and a valid cartographic basis for the study of the successive phases of the city development. The presentation will illustrate the characteristics of this cartographic source, the results obtained from the georeferencing process and the construction of a GIS system for the city of Rome in the 18th century. The described methodology stands at the basis of the first volume of the Atlas, that will be shortly published in printable as well as in digital version, in a CD Rom containing a graphical interface that permits the interactive interrogation of map and databases.

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

Wegener, Mai

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. Its basic assumption is that the relationship between the body and the psyche is itself constituted by language.

Contagious rhythm: infectious diseases of 20th century musicians.

2010-07-01

Infectious diseases have led to illness and death for many famous musicians, from the classical period to the rock 'n' roll era. By the 20th century, as public health improved and orchestral composers began living more settled lives, infections among American and European musicians became less prominent. By mid-century, however, seminal jazz musicians famously pursued lifestyles characterized by drug and alcohol abuse. Among the consequences of this risky lifestyle were tuberculosis, syphilis, and chronic viral hepatitis. More contemporary rock musicians have experienced an epidemic of hepatitis C infection and HIV/AIDS related to intravenous drug use and promiscuity. Musical innovation is thus often accompanied by diseases of neglect and overindulgence, particularly infectious illnesses, although risky behavior and associated infectious illnesses tend to decrease as the style matures.

Beginnings of Astigmatism Understanding and Management in the 19th Century.

Within the last 200 years, the perception of astigmatism has evolved from that of an infrequent and peculiar defect of the eye to a distortion almost as common as spherical refractive errors. Most of the significant findings on this condition were made in the 19th century, including the first description by Thomas Young (1773-1829) and the introduction of the treatment methods used today. The purpose of this study was to investigate the milestones in the understanding and management of astigmatism that occurred up to the year 1900. This fascinating history illustrates how knowledge evolves across time, geographical areas, and interdisciplinary boundaries. The first article looking at the use of a cylindrical lens to correct astigmatism was written by George Airy (1801-1892) in 1825. The term "astigmatism" was introduced in by William Whewell (1794-1866) in 1846. Methods for subjective and objective evaluation were subsequently established, including the introduction of a cross cylinder, keratoscope, astigmatic dial, and the development of retinoscopy and ophthalmoscopy. In the last two decades of the 19th century, the first attempt to alter the refraction in astigmatic patients by changing the shape of the cornea was made. It must be noted that diverse challenges were encountered in this field on the way to the development of a treatment, including the technical manufacture of a lens, the precise measurement of the refractive error, and understanding the optical properties of the eye. The importance of the 19th century was that interdisciplinary cooperation, such as that seen in this study, between physicists and astronomers, and mathematicians and physicians, led to the development of comprehensive knowledge on astigmatism.

To see whether a collection of portraits depicting inhabitants of a defined geographical region and covering several centuries is a useful source for studying the sociocultural significance and epidemiology of particular visible diseases, such as goitre, which is known to have been common in this region. Systematic review of portraits and description of visible signs of illness. The Burgerbibliothek (archives of the burghers' community) in Berne, Switzerland. 3615 portraits; 2989 of individuals whose identity is known and 626 of individuals whose identity is unknown. Visible signs of illness evaluated by means of a standardised visual assessment. Visible signs of illness in portraits were common and appeared in up to 82% (451/553) of paintings from the 17th and 18th centuries. The most common findings were signs of goitre in women and overweight in men. In only the portraits where the neck region could be evaluated, 41% of women with known identities (139/343) had goitre compared with 24% of men with known identities (21/86). The prevalence of goitre was even higher in sitters whose identities were unknown: 63% in men (5/8) and 68% in women (82/121). Overweight in people with known identities was more common in men than in women (30%, 346/1145 v 44%, 811/1844). Overweight was most common in sitters aged >40 than in those aged 40 or younger. Other conditions, such as missing teeth, amputated limbs, or osteoarthritic deformations were surprisingly rare in the portraits under evaluation. Goitre and other diseases are under-represented in the people depicted in these portraits. Artistic idealisation is a likely explanation for this observation: what was reproduced depended on what was considered pathological or shameful at the time, and therefore depended on age and sex. Stigmatising details may have been omitted. Further, artistic skills and contemporary fashion may have influenced the way in which people were reproduced. People depicted are possibly not

The results of dendrochronological and radiocarbon dating by means of accelerator mass spectrometry (AMS) of six medieval icons, originating from northern European Russia and painted on wooden panels made from Scots pine, dated to the 15th to 17th centuries are presented. The panels of each icon were studied using dendrochronology. Five to six AMS dates were obtained for four icons. Although five icons were dendro-dated successfully, one failed to be reliably cross-dated with the existing master tree-ring chronologies and it was dated by radiocarbon wiggle-matching. Dendrochronological dating and wiggle-matching of radiocarbon dates allowed us to determine the narrow chronological intervals of icon creation.

Drosophila melanogaster and the development of biology in the 20th century.

The fruit fly Drosophila has played a central role in the development of biology during the 20th century. First chosen as a convenient organism to test evolutionary theories soon became the central element in an elaborate, fruitful, and insightful research program dealing with the nature and function of the gene. Through the activities of TH Morgan and his students, Drosophila did more than any other organism to lay down the foundations of genetics as a discipline and a tool for biology. In the last third of the century, a judicious blend of classical genetics and molecular biology focused on some mutants affecting the pattern of the Drosophila larva and the adult, and unlocked the molecular mechanisms of development. Surprisingly, many of the genes identified in this exercise turned to be conserved across organisms. This observation provided a vista of universality at a fundamental level of biological activity. At the dawn of the 21st century, Drosophila continues to be center stage in the development of biology and to open new ways of seeing cells and to understand the construction and the functioning of organisms.

Recent Increase in North Atlantic Jet Variability Emerges from Three-Century Long Context

Trouet, V.; Babst, F.; Meko, M. D.

2017-12-01

The position and strength of the Northern Hemisphere polar jet stream are important modulators of mid-latitude weather extremes and their societal, ecosystem, and economic impacts. A recent increase in mid-latitude extreme events highlights the need for long-term records of jet stream variability to put recent trends in a historical perspective and to investigate non-linear relationships between jet stream variability, mid-latitude extreme weather events, and anthropogenic climate change. In Europe, anomalies of the North Atlantic Jet (NAJ) create a summer temperature seesaw between the British Isles (BRIT) and the northeastern Mediterranean (NEMED). We combined summer temperature-sensitive tree-ring records from BRIT and NEMED to reconstruct inter-annual variability in the latitudinal position of the August NAJ back to 1725 CE. The two temperature proxies BRIT and NEMED counter-correlate significantly over their period of overlap, thus illustrate the temperature dipole generated by anomalous NAJ positions, and combined explain close to 40% of the variance in the August NAJ target (Fig. 1). The NAJ reconstruction is dominated by sub-decadal variability and no significant long-term poleward or equatorward trends were detected. However, the NAJ time series shows a steep and unprecedented increase in variance starting in the late 1960s. Enhanced late 20th century variance has also been detected in climate and ecosystem dynamics in the Central and Northeast Pacific, which are associated with the latitudinal position of the North Pacific Jet. Our combined results suggest a late 20th century increase in jet stream latitudinal variance in the North Atlantic and the North Pacific Basin that can be indicative of enhanced jet stream waviness and that coincides with a recent increase in quasi-resonant amplification (QRA). Our results show a late 20th century amplification of meridional flow in both the North Pacific and the North Atlantic Basin and support more sinuous jet

Quantifying the contribution from ice sheets and glaciers to past sea level change is of great value for understanding sea level projections into the 21st century. However, quantifying and understanding past changes are equally important, in particular understanding the impact in the near-field where the signal is highest. We assess the impact of 20th century mass balance of the Greenland Ice Sheet on land motion using results from Kjeldsen et al, 2015. These results suggest that the ice sheet on average lost a minimum of 75 Gt/yr, but also show that the mass balance was highly spatial- and temporal variable, and moreover that on a centennial time scale changes were driven by a decreasing surface mass balance. Based on preliminary results we discuss land motion during the 20th century due to mass balance changes and the driving components surface mass balance and ice dynamics.

Roman city Cibalae (Vinkovci) - the birthplace of Roman emperors Valentinian I and Valens was a very well developed urban ares in the late antique what was evidenced by numerous archaeological findings. The aim of this paper is to get insight in dental health of antique population of Cibalae. One hundred individuals with 2041 teeth dated to 3rd - 5th century AD have been analyzed for caries, antemortem tooth loss, periapical diseases and tooth wear. Prevalence of antemortem tooth loss was 4.3% in males, 5.2% in females. Prevalence of caries per tooth was 8.4% in males, 7.0% in females. Compared to other Croatian antique sites, ancient inhabitants of Roman Cibalae had rather good dental health with low caries prevalence and no gender differences. Statistically significant difference was found between males in females in the prevalence of periapical lesions and degree of tooth wear. Periapical lesions were found only in males.

Evaluation of the treatment, epidemiology and outcome of cardiac arrest in the television franchise Star Trek. Retrospective cohort study of prospective events. Screening of all episodes of Star Trek: The Next Generation, Star Trek: Deep Space Nine and Star Trek: Voyager for cardiac arrest events. Documentation was performed according to the Utstein guidelines for cardiac arrest documentation. All adult, single person cardiac arrests were included. Patients were excluded if cardiac arrest occurred during mass casualties, if the victims were annihilated by energy weapons or were murdered and nobody besides the assassin could provide first aid. Epidemiological data, treatment and outcome of cardiac arrest victims in the 24th century were studied. Ninety-six cardiac arrests were included. Twenty-three individuals were female (24%). Cardiac arrest was witnessed in 91 cases (95%), trauma was the leading cause (n = 38; 40%). Resuscitation was initiated in 17 cases (18%) and 12 patients (13%) had return of spontaneous circulation. Favorable neurological outcome and long-term survival was documented in nine patients (9%). Technically diagnosed cardiac arrest was associated with higher rates of favorable neurological outcome and long-term survival. Neurological outcome and survival did not depend on cardiac arrest location. Cardiac arrest remains a critical event in the 24th century. We observed a change of etiology from cardiac toward traumatic origin. Quick access to medical help and new prognostic tools were established to treat cardiac arrest.

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

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.

Early 20th Century Arctic Warming Intensified by Pacific and Atlantic Multidecadal Variability

NASA Astrophysics Data System (ADS)

Tokinaga, H.; Xie, S. P.; Mukougawa, H.

2017-12-01

We investigate the influence of Pacific and Atlantic multidecadal variability on the Arctic temperature, with a particular focus on the early 20th century Arctic warming. Arctic surface air temperature increased rapidly over the early 20th century, at rates comparable to those of recent decades despite much weaker greenhouse gas forcing than at present. We find that the concurrent phase shift of Pacific and Atlantic multidecadal variability is the major driver for the early 20th century Arctic warming. Atmospheric model simulations reproduce the early Arctic warming when the interdecadal variability of sea surface temperature (SST) is properly prescribed. The early Arctic warming is associated with the cold-to-warm phase shifts of Atlantic and Pacific multidecadal variability modes, a SST pattern reminiscent of the positive phase of the Pacific decadal and Atlantic multidecadal oscillations. The extratropical North Atlantic and North Pacific SST warming strengthens surface westerly winds over northern Eurasia, intensifying the warming there. The equatorial Pacific warming deepens the Aleutian low, advecting warm air to the North American Arctic. Coupled ocean-atmosphere simulations support the constructive intensification of Arctic warming by a concurrent, cold-to-warm phase shift of the Pacific and Atlantic multidecadal variability. Our results aid attributing the historical Arctic warming and thereby constrain the amplified warming projected for this important region.

2012-01-01

The large-scale state psychiatric hospitals, referred to as "asylums," were built in the USA in the 19th century and generally have a bad reputation in Japan as institutions with an unpleasant environment for the patients. Asylums were not built for institutionalizing mental patients. The original meaning of the word asylum is a "retreat" or "sanctuary," and these institutions were originally built to act as sanctuaries for the protection of mental patients. The field of psychiatric medicine in western countries in the 19th century began to embrace the concept of "moral treatment" for mental patients, including no restraint of the patients and treating them in a more open environment. With this background, asylums were built according to the efforts of social activist Dorothea Dix with financial assistance from the Quakers. The psychiatrist Dr. Thomas Kirkbride had a large influence on asylum architecture, and believed that the hospital building and environment as well as location have healing effects on the patients, which he called the "therapeutic landscape". Kirkbridelater proposed an architectural plan that became the basis for subsequent mental hospital architecture, and many asylums were built according to this plan. As the architecture was considered part of the treatment, many leading architects and landscape architects at the time became involved in building asylums. In the later half of the 19th century, over 150 asylums were built across the USA. However, moral treatment fell out of favor toward the end of the 19th century, and the concept of therapeutic landscape was also neglected. The hospitals had many uncured patients, and caregivers became pessimistic about the efficacy of the treatments. Abuse and neglect of the patients were also common. The environment at the asylums deteriorated, which created the image of asylums that, we hold today. Many asylums have been demolished or abandoned. These early attempts at asylum failed due to insufficient

The decline of winter monsoon velocity in the South China Sea through the 20th century: Evidence from the Sr/Ca records in corals

A modern massive Porites coral was collected from the Longwan Bay (19??20???N, 110??39???E) on the east coast of the Hainan Island, China. The coral was sectioned vertical to the growth axis into discs of double density-bands representing annual growth. The samples were analyzed for the Sr/Ca ratio by inductively coupled plasma atomic emission spectrometry. The history of winter sea-surface temperature (SST) is reconstructed using the Sr/Ca ratio in winter bands of corals. The winter SST at Xisha in the middle of the South China Sea (SCS) is weakly correlated with the instrument-measured winter monsoon velocity (WMV) with a correlation coefficient of 0.19. The winter SST data from corals at Longwan Bay, Hainan, in the northern SCS are moderately correlated with the WMV (r = 0.40). Interestingly we found that the difference of winter SSTs between the two sites (Xisha and Longwan Bay, Hainan) (the X-H index) is significantly negatively correlated with the WMV (r = - 0.73). This negative correlation may be related to the intrusion of the warm Kuroshio Current into the SCS through the Luzon Strait promoted by the strong northeastern monsoon winds in the winter. Using the relationship between our coralline data and observed WMV, the calculated winter monsoon velocity (WMVc) was obtained for 87??years. This data set in combination with the instrument-measured data between 1993 and 1998 generate a record of WMVc for a period of 93??years from 1906 to 1998. The WMVc in the 20th century shows significant interannual and decadal variability with a trend of persistent decline in the whole 20th century at the rate of decrease of - 0.02 (m/s)/a. The lowest wind velocity occurred during the last two decades of the 20th century. The WMVc has decreased significantly by about 30% from the early to the late of 20th century. The 20th century decline of winter monsoon velocity evidenced from the SCS coral records is consistent with the atmosphere-ocean general circulation models

Abrupt and severe 20th Century changes in the fire regimes of southeastern Australia: Evidence from a 3000 year multi-proxy analysis

Fire is the dominant natural disturbance in southeastern Australia. For millennia it has been the driving force shaping terrestrial ecosystems in the region -- simultaneously killing vegetation and initiating regeneration across whole landscapes. Fire regimes across the region are driven by several factors including climate, vegetation, and ignition sources. Humans have been a significant contributing factor to past and present fire regimes. Prior to European settlement in the late 1700s, Aboriginal Australians used frequent, low-intensity fires to manage vegetation across much of the landscape. European settlement led to the displacement of Aboriginal communities and a shift to active fire suppression and control. This changing approach to fire management is widely believed to have initiated a fundamental shift towards extreme, high-intensity fire events as fuel loads increased. In addition, during the 20th Century prolonged periods of warm, dry conditions have occurred with greater frequency and intensity. The relative importance of climate and fire management practices on contemporary fire regimes is vigorously debated in Australia and is directly relevant to land management policies and their implementation. To put the current fire regime into historical context, we used a multi-proxy approach combining palaeo-charcoal and tree-ring analyses to assess how fire regimes have changed over the last 3000 years in the Snowy Mountains region of southeastern Australia. We found almost no evidence of high-intensity fires in the 3000 years that preceded the 20th Century. However, in the mid-20th Century there is a sudden and dramatic increase in the presence of charcoal and the pulsed establishment of trees across the landscape, suggesting a recent shift from low-intensity fires with minimal charcoal signatures to moderate- to high-intensity fires with substantial charcoal inputs. Importantly, the tree-ring data demonstrate that most of these fires were not stand

At least four of the sultans who ruled during the 19th century suffered from tuberculosis (TB), and probably many of the women and children in the harem too. Life there was crowded with low standards of hygiene, resulting in high mortality, especially among children. Infectious diseases were the main killers and TB was one of the many factors behind the decline and fall of the empire.

Medicine declared itself to be a scientific discipline in the 19th century, and radically cut off its former links with the Hippocratic-Galenic tradition after the French Revolution in 1789. Owing to the great progress made in physics and chemistry, these disciplines came to be regarded as the only ones capable of solving medical problems. This is a reductionist view, in contrast to the vitalist view, which still believed in the existence of the Hippocratic physis or life force. Reductionist medicine led to great advances, though in the 19th century much of the wisdom of earlier times tended to be forgotten, to the detriment of medicine as a whole. It was believed that medicine and science could solve all the world's problems, a belief that, in modern times, has been abandoned as invalid. We now need a new medical anthropology, or rather medicine that is anthropological in its thinking.

From the mid-18th century, several different stimulations were used to attempt to resuscitate apparently dead people. These include sound, smell, and light stimulation to the ear, nose and eyes, rubbing the body surface and spirit given to the oral cavity. The most notable stimulation was use of electricity, which was initiated by better understanding of its power by Benjamin Franklin and Luigi A. Galvani. Charles Kite developed the first electrical machine to stimulate the heart, and by 1800, it was found that the most effective site for applying electricity was over the heart.

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

An early observation on the anatomy of the inguinal canal and the etiology of inguinal hernias by Petrus Camper in the 18th century.

The famous Dutch medical doctor Petrus Camper (1722-1789) was appointed professor of anatomy and surgery at the University of Franeker, Amsterdam, and Groningen. As Praelector Anatomiae of the Amsterdam Guild of Surgeons, he gave public anatomy lessons in the Anatomy theatre in Amsterdam. During the mid 18th century he performed dissections on corpses of children and adults to investigate the anatomy and etiology of inguinal hernias. The concept that a hernia was caused by "a rupture of the peritoneum" was common at that time. Camper concluded that this was incorrect and provided a clear description of the etiology of hernias in children and adults. For the treatment of inguinal hernias, he designed a truss based on the geometrical proportions of the pelvis. This "truss of Camper" was much used and internationally renowned. His anatomical studies and perfect, self-drawn illustrations contributed to a better understanding of the anatomy of the inguinal canal, on the national as well as international level. Camper's "Icones Herniarum" is his most widely known work on inguinal hernias and included a series of outstanding anatomical illustrations. Petrus Camper should be considered one of the pioneers in the field of inguinal hernias.

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

Documentary evidence for changing climatic and anthropogenic influences on the Bermejo Wetland in Mendoza, Argentina, during the 16th-20th century

NASA Astrophysics Data System (ADS)

Prieto, M. R.; Rojas, F.

2012-05-01

This paper examines the processes underlying changes to the once-extensive Bermejo Wetland, east of the city of Mendoza, Argentina (32°55' S, 68°51' W). Historical documents and maps from the 16th to 20th century are used to reconstruct environmental shifts. Historical documents indicate periods of increased snowfall in the adjacent Andes mountains, as well as high flow volumes in the Mendoza River. Data from georeferenced maps, the first from 1802 and the last from 1903, reflect the changes in the surface area of the wetland. The combined data sets show pulses of growth and retraction, in which major expansions coincided with more intense snowstorms and increased flow in the Mendoza River, which in turn influenced socio-economic activities. The wetland became progressively drier during the 19th century, before drying up completely around 1930, due in part to the construction of drainages and channels.

Dendrochronology and late Holocene history of Bering piedmont glacier, Alaska

Wiles, G.C.; Post, A.; Muller, E.H.; Molnia, B.F.

1999-01-01

Fluctuations of the piedmont lobe of Bering Glacier and its sublobe Steller Glacier over the past two millennia are reconstructed using 34 radiocarbon dates and tree-ring data from 16 sites across the glaciers' forelands. The general sequence of glacial activity is consistent with well-dated fluctuations of tidewater and land-terminating glaciers elsewhere along the Gulf of Alaska. Extensive forested areas along 25 km of the Bering ice margin were inundated by glacio-lacustrine and glacio-fluvial sediments during a probable ice advance shortly before 500 cal yr A.D. Regrowth of forests followed the retreating ice as early as the 7th century A.D., with frequent interruptions of tree growth due to outwash aggradation. Forests overrun by ice and buried in outwash indicate readvance about 1080 cal yr A.D. Retreat followed, with ice-free conditions maintained along the distal portions of the forefield until the early 17th century after which the ice advanced to within a few kilometers of its outer Neoglacial moraine. Ice reached this position after the mid-17th century and prior to 200 yr ago. Since the early 20th century, glacial retreat has been punctuated by periodic surges. The record from forests overrun by the nonsurging Steller Lobe shows that this western ice margin was advancing by 1250 A.D., reaching near its outer moraine after 1420 cal yr A.D. Since the late 19th century, the lobe has dominantly retreated.

"Diarium patris ministri", a Jesuit view of social structures at the break of 18th century in south-west Bohemian town of Klatovy.

Cerný, Karel

2009-01-01

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

Ballistic blocks around Kīlauea Caldera: Their vent locations and number of eruptions in the late 18th century

USGS Publications Warehouse

Swanson, Donald A.; Zolkos, Scott P.; Haravitch, Ben

2012-01-01

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

Previous studies of mid-19th century American heights and body mass index values have used potentially unrepresentative groups-students in military academies, prisoners, and African Americans. This paper uses an alternative source with heights and weights of ordinary people employed in a wide variety of occupations. The results reveal the operation of the antebellum paradox in that average heights declined between men born circa 1820 and those born circa 1840. Average weights also declined for adult males, suggesting a decline in mid-19th century nutritional status. 2010 Elsevier B.V. All rights reserved.

The early vs the late 20th century Arctic warming: The role of energy and aerosol fluxes in reanalysis driven datasets

Wegmann, Martin; Broennimann, Stefan

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

A method to reconstruct long precipitation series using systematic descriptive observations in weather diaries: the example of the precipitation series for Bern, Switzerland (1760-2003)

In contrast to barometric and thermometric records, early instrumental precipitation series are quite rare. Based on systematic descriptive daily records, a quantitative monthly precipitation series for Bern (Switzerland) was reconstructed back to the year 1760 (reconstruction based on documentary evidence). Since every observer had his own personal style to fill out his diary, the main focus was to avoid observer-specific bias in the reconstruction. An independent statistical monthly precipitation reconstruction was performed using instrumental data from European sites. Over most periods the reconstruction based on documentary evidence lies inside the 2 standard errors of the statistical estimates. The comparison between these two approaches enables an independent verification and a reliable error estimate. The analysis points to below normal rainfall totals in all seasons during the late 18th century and in the 1820s and 1830s. Increased precipitation occurred in the early 1850s and the late 1870s, particularly from spring to autumn. The annual precipitation totals generally tend to be higher in the 20th century than in the late 18th and 19th century. Precipitation changes are discussed in the context of socioeconomic impacts and Alpine glacier dynamics. The conceptual design of the reconstruction procedure is aimed at application for similar descriptive precipitation series, which are known to be abundant from the mid-18th century in Europe and the U.S.

Analyzing the 20th century Colombian legal framework from the point of view of labor law, social security and public health for identifying concepts regarding occupational health and professional risk and trying to establish convergence and differences between such foci and whether they fulfilled a complementary view. This work involved documentary research by means of thematic categorical analysis of the laws and statutes promulgated in 20th century Colombia, considering the main element or entity which should have regulated that related to professional risk or occupational health. The development of the 20th century Colombian legal framework regarding health at work was periodized, revealing the predominance of a view of social law focused on protecting dependent workers' work-related risks, as part of a tendency extending to the Colombian Sistema General de Riesgos Laborales. The proposed stages used for organizing the legal framework concerning social security regarding professional risk and occupational health facilitated some important elements being recognized concerning the social, legal and institutional context from which workers' health laws emerged. Tension was noted concerning statutes orientated towards redress and compensation regarding accidents at work and legislation emphasizing prevention.

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

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

NASA Astrophysics Data System (ADS)

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].

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.

Late 20th Century benthic foraminiferal distribution in Central San Francisco Bay, California: Influence of the Trochammina hadai invasion

2014-01-01

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

Responses of molluscan communities to centuries of human impact in the northern Adriatic Sea

PubMed Central

Haselmair, Alexandra; Tomašových, Adam; Stachowitsch, Michael; Zuschin, Martin

2017-01-01

In sediment cores spanning ~500 years of history in the Gulf of Trieste, down-core changes in molluscan community structure are characterized by marked shifts in species and functional composition. Between the 16th and 19th century, a strong heavy metal contamination of the sediments, most notably by Hg, together with the effects of natural climatic oscillations (increased sedimentation and organic enrichment) drive community changes. Since the early 20th century up to 2013, the combined impacts of cultural eutrophication, frequent hypoxic events and intensifying bottom trawling replace heavy metal contamination and climatic factors as the main drivers. The pollution-tolerant and opportunistic bivalve Corbula gibba and the scavenging gastropod Nassarius pygmaeus significantly increase in abundance during the 20th century, while species more sensitive to disturbances and hypoxia such as Turritella communis and Kurtiella bidentata become rare or absent. An infaunal life habit and scavenging emerge as the dominant life strategies during the late 20th century. Down-core shifts in the proportional abundances of molluscan species and functional groups represent a sensitive proxy for past ecological changes and reveal a century-long anthropogenic impact as the main driver behind these processes in the northern Adriatic Sea, offering also a unique perspective for other shallow marine ecosystems worldwide.

Human impacts on 20th century fire dynamics and implications for global carbon and water trajectories

NASA Astrophysics Data System (ADS)

Li, F.; Lawrence, D. M.; Bond-Lamberty, B. P.

2017-12-01

Fire is a fundamental Earth system process and the primary ecosystem disturbance on the global scale. It affects carbon and water cycles through its impact on terrestrial ecosystems, and at the same time, is regulated by weather and climate, vegetation characteristics, and, importantly, human ignition and efforts to suppress fires (i.e., the direct human effect on fire). Here, we utilize the Community Land Model version 4.5 (CLM4.5) to generate a quantitative understanding of the impacts on fire dynamics and associated carbon and water cycling that can be attributed to changes in human ignition and suppression over the 20th century. We find that the net impact of increases in human ignition and suppression significantly reduce the 20th century averaged global burned area by 38 Mha/yr. The reduction increases since 1920, rising to 103 Mha/yr less burned area at the end of the century. Land carbon gain is weakened by 17% over the 20th century, mainly due to increased human deforestation fires and associated escape fires (i.e., degradation fires) in the tropical humid forests, even though the decrease in burned area in many other regions due to human fire suppression acts to increase land carbon gain. The direct human effect on fire also weakens the 20th century upward trend of global runoff by 6%, and enhances the upward trend in global evaportranspiration since 1945 by 7%. In addition, the above impacts in densely populated, highly developed (if population density > 0.1 person/km2), or moderately populated and developed regions are of opposite sign to those in other regions. Our study suggests that particular attention should be paid to human deforestation and degradation fires in the tropical humid forests when reconstructing and projecting fire carbon emissions and net atmosphere-land carbon exchange and estimating resultant impacts of direct human effect on fire.

We will present a synthesis of the archeointensity data spanning the past millennium that we recently acquired in the European part of Russia. These data were principally obtained from groups of architectural brick fragments sampled in the Novgorod, Moscow and Yaroslavl areas that are precisely dated between the 12th and the 19th century thanks to archives and archeological constraints. All intensity measurements were carried out using the experimental protocol developed for the Triaxe magnetometer. The reliability of the data is attested through the use of stringent selection criteria on the Triaxe data, rock magnetic experiments and by the use of two different cooling rates for laboratory thermoremanent magnetization acquisition. Altogether the new data show a progressive decrease of the geomagnetic field intensities in Northwestern-Central Russia over the past millennium. They do not exhibit large and rapid fluctuations, as those previously reported from the Balkan archeointensity dataset. They further allow us to constrain the dipole moment evolution over the past four centuries. Finally, we will discuss the consistency of the geomagnetic field intensity variations during the second millennium AD at the entire European scale. The research was supported by RSF (project No. 16-17-10097)

Cast Iron in The 19th Century Building Equipment

2017-10-01

Cast iron is a material, characteristics of which enable to receive extremely artistic elements. It maintains good strength properties at the same time. That combination of these seemingly contrary traits makes it a commodity that was widely used in the 19th century industry and architecture. These usages were not only as decorative elements, technical and structural ones. The production of new household utilities started, which made people’s lives more comfortable. Cast iron allowed for fast and cheap production while maintaining high aesthetic qualities. Useful elements, which often were ornamental parts of buildings were created. The aim of the article is to characterise elements of interior equipment of the 19th century building that are made of cast iron. As it appears from performed bibliography, archival and field studies, the ways of exploitation are very broad. Some were mounted into the building; the others were a mobile equipment. As it occurred they were most commonly used as functional items. Cast iron was used to produce the minor elements, which were only parts of the bigger wooden or stone items. Notwithstanding, there were also bigger ones casted as a whole, and frequently ones that were assembled from many elements. Nowadays, elements of an interior feature are one of the subjects of study during the restoration work of the buildings. They can provide important information about the building and the way people lived and are considered as the essential part of historical objects.

1998-01-01

The author makes an attempt at considering the most important achievements in psychiatry which have taken place in the global scale during the passing century, and the direction taken up by the development of global psychiatry in the coming century. The 20th century was characterised not only by the impressive development of science, thanks to which completely new possibilities opened up for global psychiatry, but also by the presence of extreme events that took place as a result of false ideologies such as fascism and communism. In the 20th century concepts like homicide, holocaust, the extermination of the mentally ill, experiments on people that are prohibited by the ethics of medicine and the elementary rules of humanity, etc. The paper includes the achievements of diagnosis and therapy of psychiatric disorders and the latest organisational solutions as well as the perspectives for further development of psychiatry. The author also implies the aims that psychiatry has to take up due to the numerous threats from our civilization: the technical-technological development, pollution of the natural environment, the negative changes in human values, the rising brutality in interhuman relations due to racial, national and religious conflicts and terrorism, the disappearing feeling of being safe in society, vision of hunger and poverty in many countries on a few continents, the danger of an epidemic outbreak of new unknown diseases caused by viral mutations, or genetics--the possible negative effects of genetic engineering (cloning of humans), etc. The author tries to define the role of psychiatry in preventing the threats of civilization.

Several scenario experiments of the IPCC 4th Assessment Report (AR4) are performed by version g1.0 of a Flexible coupled Ocean-Atmosphere-Land System Model (FGOALS) developed at the Institute of Atmospheric Physics, Chinese Academy of Sciences (IAP/CAS), including the “Climate of the 20th century experiment”, “CO2 1% increase per year to doubling experiment” and two separate IPCC greenhouse gases emission scenarios A1B and B1 experiments. To distinguish between the different impacts of natural variations and human activities on the climate change, three-member ensemble runs are performed for each scenario experiment. The coupled model simulations show: (1) from 1900 to 2000, the global mean temperature increases about 0.5°C and the major increase occurs during the later half of the 20th century, which is in consistent with the observations that highlights the coupled model’s ability to reproduce the climate changes since the industrial revolution; (2) the global mean surface air temperature increases about 1.6°C in the CO2 doubling experiment and 1.5°C and 2.4°C in the A1B and B1 scenarios, respectively. The global warming is indicated by not only the changes of the surface temperature and precipitation but also the temperature increase in the deep ocean. The thermal expansion of the sea water would induce the rise of the global mean sea level. Both the control run and the 20th century climate change run are carried out again with version g1.1 of FGOALS, in which the cold biases in the high latitudes were removed. They are then compared with those from version g1.0 of FGOALS in order to distinguish the effect of the model biases on the simulation of global warming.

The forgotten history of defunct black medical schools in the 19th and 20th centuries and the impact of the Flexner Report.

There are currently four medical schools dedicated primarily to training African-American physicians. Two of these schools were established in the last 40 years. For a generation prior to that, only Howard University College of Medicine and Meharry Medical College existed. Forgotten is the history of black medical schools established in the 19th and early 20th centuries, most of which are now defunct. While barriers to the medical education of African Americans in majority institutions have largely disappeared, the continued education of students at our four present-day black medical schools is again threatened. It is incumbent upon us not to allow these modern-day threats to destroy an important resource and legacy in the annals of African-American people. This paper explores medical education in the 19th and 20th centuries, the creation of black medical schools and the forces that lead to the demise of many of these institutions. In recalling this history, we acknowledge the almost-impossible odds faced by these pioneers and learn from their mistakes and failures. PMID:17019907

Religious social movements are very interesting to be studied because this phenomenon is affecting the urban and rural communities, among the rich and the poor people, the educated and the less educated. The purpose of this study was to analyze several religious social movements in Java in the 19Th - 20Th centuries. The methods used are historical methods that include: Source feeding (main source is reference), Source Critique (source test), Interpretation of fact (analyzing the fact), and Historiography (writing research results) in the form of Journal Articles. Religious Social Symbols arise as a result of a depressed society, oppressed by the political system, or poverty as a result of colonial exploitation. For indigenous and less religious societies social pressures breed social protest movements and social revolutions. Meanwhile, in the Javanese society that has social and religious characteristics make the nature of the movement multidimensional. The form of movement is a blend of social movements that lead in the form of protests and revolutions, on the other hand formed religious movements that are politer nature because it is related to the life of the world and the hereafter. In various religious social movements in Java include the Nativist movement, Millennial/millenarianism, Messianic, Nostalgic, sectarian, and Revivalist. The movement emerged as a social impact of the Dutch colonization in the form of Cultivation which gave birth to the suffering of the people in the economic and social fields.

Surface Temperature (ST) over India has increased by ~0.055 K/decade during 1860-2005 and follows the global warming trend. Here, the natural and external forcings (e.g., natural and anthropogenic) responsible for ST variability are studied from Coupled Model Inter-comparison phase 5 (CMIP5) models during the 20 th century and projections during the 21 st century along with seasonal variability. Greenhouse Gases (GHG) and Land Use (LU) are the major factors that gave rise to warming during the 20 th century. Anthropogenic Aerosols (AA) have slowed down the warming rate. The CMIP5 projection over India shows a sharp increase in ST under Representative Concentration Pathways (RCP) 8.5 where it reaches a maximum of 5 K by the end of the 21 st century. Under RCP2.6 emission scenarios, ST increases up to the year 2050 and decreases afterwards. The seasonal variability of ST during the 21 st century shows significant increase during summer. Analysis of rare heat and cold events for 2080-2099 relative to a base period of 1986-2006 under RCP8.5 scenarios reveals that both are likely to increase substantially. However, by controlling the regional AA and LU change in India, a reduction in further warming over India region might be achieved.

Physiology of Penile Erection—A Brief History of the Scientific Understanding up till the Eighties of the 20th Century

2015-01-01

Abstract Introduction Understanding the physiology of penile erection is important for all who work in the field of sexual medicine. Aim The aim of this study was to highlight and analyze historical aspects of the scientific understanding of penile erection. Methods (i) Review of the chapters on the physiology of erection out of the author's collection of books dealing with male sexual functioning published in the German, French, Dutch, and English language in between 1780 and 1940. (ii) Review of the topic “physiology of penile erection” of relevant chapters of C lassical writings on erectile dysfunction. A n annotated collection of original texts from three millennia, including the study of all relevant references mentioned in these books. Main Outcome Measure The main outcome measure used for the study was the scientific understanding of the physiology of penile erection. Results In Antiquity, Galen considered penile erection as the result the accumulation of air. His ideas so dominated medieval medicine that nearly everyone then alive was a Galenist. The beginning of the Renaissance shows meaningful examples of experimental scientific work on the penis. Da Vinci correctly concluded that erections were caused by blood, and in the 18th century, Von Haller from Switzerland was the first who explained that erections were under the control of the nervous system. In the 19th century, a mindset that emphasized on experimentation determined a new direction, namely experimental physiology. Animal studies clarified that stimulation of the nervi erigentes‐induced small muscle relaxation in the corpora cavernosa. Nearly all were published in the German language. That may be one of the reasons that the existence of the concept of smooth muscle relaxation remained controversial until the first World Congress on Impotence in 1984 in Paris. Conclusions As the Renaissance's innovative research defined neural and vascular physiologic phenomena responsible for penile

The little death: Rigoni-Stern and the problem of sex and cancer in 20th-century biomedical research.

Aviles, Natalie B

2015-06-01

Approaches to the organization and conduct of cancer research changed dramatically throughout the 20th century. Despite marked differences between the epidemiological approaches of the first half of the century and molecular techniques that gained dominance in the 1980s, prominent 20th-century researchers investigating the link between sexual activity and anogenital cancers continuously invoked the same 1842 treatise by Italian surgeon Domenico Rigoni-Stern, who is said to originate the problem of establishing a causal link between sex and cancer. In this article, I investigate 20th-century references to Rigoni-Stern as a case of a broader phenomenon: scientists situating their work through narratives of venerated ancestors, or originators. By explaining shifting versions of originator narratives in light of their authors' cultural context and research practices, we can reimagine as meaningful cultural symbols the references that previous scholars have treated as specious rhetorical maneuvers. In this case, references to Rigoni-Stern provide an interpretive anchor for American scientists to construct continuity between their work and a diverse historical legacy of cancer research.

[From ancient pot collections to the modern medicines. Menier's pot collection-19th century].

PubMed

Demouy, Isabelle

2012-02-01

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.

Radiosyntheses using Fluorine-18: the Art and Science of Late Stage Fluorination

Positron (β+) emission tomography (PE) is a powerful, noninvasive tool for the in vivo, three-dimensional imaging of physiological structures and biochemical pathways. The continued growth of PET imaging relies on a corresponding increase in access to radiopharmaceuticals (biologically active molecules labeled with short-lived radionuclides such as fluorine-18). This unique need to incorporate the short-lived fluorine-18 atom (t1/2 = 109.77 min) as late in the synthetic pathway as possible has made development of methodologies that enable rapid and efficient late stage fluorination an area of research within its own right. In this review we describe strategies for radiolabeling with fluorine-18, including classical fluorine-18 radiochemistry and emerging techniques for late stage fluorination reactions, as well as labeling technologies such as microfluidics and solid-phase radiochemistry. The utility of fluorine-18 labeled radiopharmaceuticals is showcased through recent applications of PET imaging in the healthcare, personalized medicine and drug discovery settings. PMID:24484425

Nelson's wound: treatment of spinal cord injury in 19th and early 20th century military conflicts.

PubMed

Hanigan, William C; Sloffer, Chris

2004-01-15

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.

The process of Danish nurses' professionalization and patterns of thought in the 20th century.

PubMed

Beedholm, Kirsten; Frederiksen, Kirsten

2015-06-01

In this article, we address how the professionalization process is reflected in the way Danish nursing textbooks present 'nursing' to new members of the profession during the 20th century. The discussion is based on a discourse analysis of seven Danish textbooks on basic nursing published between 1904 and 1996. The analysis was inspired by the work of Michel Foucault, in particular the concepts of rupture and rules of formation. First, we explain how the dominating role of the human body in nursing textbooks disappears in the mid-20th century. This transformation can of course be attributed to changes in tasks and responsibilities for nurses or to the implementation of increasing amounts of knowledge and theories from other disciplines than medicine into the nurses' knowledge base. However, inspired by Foucault, we consider these historical changes to be the conditions of possibilities and not causes. The second part of the analysis shows that along with 'the disappearance of the body', a second discursive change appears: the role of doctors and medicine changes fundamentally from about mid-20th century. Finally, we argue that this discursive reorganization enabling new patterns of thought to emerge was driven by a professional interest in describing nursing as an independent profession. © 2014 John Wiley & Sons Ltd.

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

Absinthism: a fictitious 19th century syndrome with present impact

Padosch, Stephan A; Lachenmeier, Dirk W; Kröner, Lars U

2006-01-01

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.

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

Combined external milli-beam Particle Induced X-ray Emission (PIXE) and Prompt Gamma Activation Analysis (PGAA) analysis was applied to characterize the composition of paste and colorants from some fragments of Byzantine bracelets (10th-12th Centuries AD), late medieval (17th-18th Centuries AD) and modern Murano glass pieces. As fluxes, PGAA revealed the samples are soda-lime glass, except four samples - two medieval vessel white shards and two dark Byzantine fragments of bracelets - which have potash flux. Aluminium was detected in various proportions in all samples indicating different sources for the added sand. The presence of Magnesium is relevant only in one bracelet fragment suggesting the use of plant (wood?) ash and confirming that the Byzantine bracelet is manufactured from the mixture of both types of glass (natron and plant ash based). PGAA also indicated the presence of low quantities of Cadmium, high level of Arsenic and Lead (possibly lead arsenate) in one medieval sample and of ZnO in Murano glass, and of CoO traces (maximum 0.1%) in all blue-colored Byzantine, late medieval to modern Murano glass artefacts. PIXE confirmed the use of small quantities of CoO for blue color, indicated Manganese combined with Iron for dark glass, Copper for green, Lead, Tin and an Arsenic compound (orpiment?) for yellow and in the case of modern Murano glass Selenium and Cadmium to obtain a reddish color. Despite PIXE - PIGE combination is probably the best one for glass analysis, our external milli-PIXE - PGAA methods proved to be adequate complementary tools to determine many chemical elements from glass composition - Si, Na, K, Ca, Al, Mg, various metallic oxides.

"Winged sponges": houseflies as carriers of typhoid fever in 19th- and early 20th-century military camps.

PubMed

Cirillo, Vincent J

2006-01-01

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.

Premature Infant Care in the Early 20th Century.

PubMed

Prescott, Stephanie; Hehman, Michelle C

The complex early history of infant incubators provides insight into challenges faced by medical professionals as they promoted care for premature infants in the early 20th century. Despite their absence from the narrative to date, nurses played vital roles in the development of neonatal care. Working in many different settings, from incubator-baby shows to the first hospital unit designed specifically for premature infants, nurses administered quality care and promoted advanced treatment for these newborns.

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.

The place of the 17th century in Jung's encounter with China.

PubMed

Cambray, Joe

2005-04-01

After recounting several dreams and related alchemical interests of Jung's tied to the 17(th) century, a contextualizing look at select scientific and philosophical developments of that century is presented. Several precursors of the contemporary debates on the mind/body relation are noted, with special reference to the work of Antonio Damasio. This in turn leads to a reconsideration of the work of the 17(th) century polymath Gottfried Wilhelm Leibniz, which Jung read as a major precursor to his formulation of synchronicity (via Leibniz's concept of 'pre-established harmony'). Leibniz was the first philosopher to articulate the mind/body relationship in terms of supervenience, sharing an accord with those contemporary philosophers and scientists who see the mind as being an emergent property of the body-brain. Similarly, these ideas are also consistent with a reformulation of synchronicity in terms of emergence. Tracing Leibniz's interest in China reveals another set of links to Jung and to emergentism. Jung's use of Taoist concepts in developing the synchronicity principle is well known. According to scholars, Leibniz was the first major Western intellect to study the I-Ching, through the assistance of a Jesuit missionary in Beijing, Fr. Joachim Bouvet. Some details of the Leibniz-Bouvet correspondence are discussed here. Despite Helmut Wilhelm's presenting aspects of this correspondence at an Eranos conference, Jung does not appear to have integrated it into his writing on synchronicity--a possible reason for this omission is suggested.

In this work we made use of historical winds record taken aboard ships to reconstruct a series of the prevalent summer northerly winds (Etesian winds) over the Eastern Mediterranean for the entire 20th century. Previous studies have shown a significant link between the frequency and strength of these winds and the strength of the Indian Summer Monsoon (ISM), but this relationship had only been studied in detail for the second half of the 20th century due to the absence of long and continous series of observed wind in the Eastern Mediterranean for previous periods. In this work, a new climatic index, the so-called " Etesian Wind Index " (EWI), is defined as the percentage of days with prevalent northerly wind (wind blowing from 305° to 35°) in a fixed region [20E-30E, 32N-37N]. By using historical wind observations, we have been able to compute this index for the summer (JJAS) since 1880 and analyze the long term variability of the Etesians, as well as to research into its relation with the ISM at an unprecedent temporal coverage. A running coverage analysis revealed a strong and significant positive correlation between the EWI and the strength of the ISM for the period 1960-1980, more markedly in July and August. This result is in accordance with other recent studies. However, we have found that the correalation fades out in the first half of the 20th century (1900-1950) and in the period 1980-2012, even showing significant negative values around the subperiod 1920-1950. Similar indices to the EWI were computed using two different 20th century reanalysis datasets (ERA20C and 20CR-V2C). Despite the fact that both indices show some discrepancies with the EWI before 1950, the correlation analysis with the ISM revealed similar results, pointing out a strong loss of the EWI-ISM correlation in the first half of the 20th century and from 1980 onwards, as well as a marked positive correlated period between 1960 and 1980, specially in August. In this study, we show that

Collier, R J; Bauman, D E

The latter half of the 20th century and the early portion of the 21st century will be recognized as the "Golden Age" of lactation biology. This period corresponded with the rise of systemic, metabolomic, molecular, and genomic biology. It includes the discovery of the structure of DNA and ends with the sequencing of the complete genomes of humans and all major domestic animal species including the dairy cow. This included the ability to identify polymorphisms in the nucleic acid sequence, which can be tied to specific differences in cellular, tissue, and animal performance. Before this period, classical work using endocrine ablation and replacement studies identified the mammary gland as an endocrine-dependent organ. In the early 1960s, the development of RIA and radioreceptor assays permitted the study of the relationship between endocrine patterns and mammary function. The ability to measure nucleic acid content of tissues opened the door to study of the factors regulating mammary growth. The development of high-speed centrifugation in the 1960s allowed separation of specific cell organelles and their membranes. The development of transmission and scanning electron microscopy permitted the study of the relationship between structure and function in the mammary secretory cell. The availability of radiolabeled metabolites provided the opportunity to investigate the metabolic pathways and their regulation. The development of concepts regarding the coordination of metabolism to support lactation integrated our understanding of nutrient partitioning and homeostasis. The ability to produce recombinant molecules and organisms permitted enhancement of lactation in farm animal species and the production of milk containing proteins of value to human medicine. These discoveries and others contributed to vastly increased dairy farm productivity in the United States and worldwide. This review will include the discussion of the centers of excellence and scientists who labored

Koper stands out among Istrian towns of the nordeastern Adriatic coast for its highly advanced medicine. Communal service developed between the 13th and 15th century. Beside the hospital, almshouse and a quarantine, the city also boasted highly trained physicians, surgeons and barbers. Trade, crafts and navigation prospered and numerous town intellectuals established an academy whose most active members were medical doctors. The aim of this article is to give a chronological presentation of physicians related to Koper by their birth or work and of other scientists who contributed to the development of local medicine. These includes (about forty names) S. Santorio, Ser Benvenuto, P P. Vergerio, G. Nuzio, E Nuzio, P de Castaldi, I. de Albertis, L. Zarotti, B. Petronio, I. Bratti, Z. Zarotti, A.Valdera, G. Vergerio and C. Zarotti of whom some are well known. The author wishes to systematisize the bibliography, fill the gaps and show ways for further research in the archives and museums of Istria, Triest, Venice and Vienna.

snakebites. Many plants are characterised by their humoral properties, of which 'warming' is the most prevalent. Plant species were mostly used for their roots (28%), bark (16%) or leaves (11%). More Tamil names (260) were documented than Sinhalese (208). More than half of the Tamil names and 36% of the Sinhalese names are still used today. The author was probably a VOC surgeon based in northern Sri Lanka, who travelled around the island to document medicinal plant use. Less than half of the species were previously documented from Ceylon by the famous VOC doctor and botanist Paul Hermann in the 1670s. Further archival research is needed to identify the maker of this manuscript. Although the maker of this early 18th century manuscript remains unknown, the detailed, 300-year-old information on medicinal plant use in the Icones Plantarum Malabaricarum represents an important ethnobotanical treasure for Sri Lanka, which offers ample opportunities to study changes and continuation of medicinal plant names and practices over time.

The Fraser River Basin (FRB) is the largest river draining to the Pacific Ocean in British Columbia (BC), Canada, and it provides the world's most abundant salmon populations. With recent climate change, the shifting hydrologic regime of the FRB is evaluated using hydrological modeling results over the period 1949 to 2006. To quantify the contribution of snowmelt to runoff generation, the ratio RSR, defined as the division of the sum of the snowmelt across the watershed by the integrated runoff over the water year, is employed. Modeled results for RSR at Hope, BC — the furthest downstream hydrometric station of the FRB — show a significant decrease (from 0.80 to 0.65) in the latter part of the 20th century. RSR is found to be mainly suppressed by a decrease of the snowmelt across the FRB with a decline with 107 mm by 26 % along the simulation period. There is also a prominent shift in the timing of streamflow, with the spring freshet at Hope, BC advancing 30 days followed by reduced summer flows for over two months. The timing of the peak spring freshet becomes even earlier when moving upstream of the FRB owing to short periods of time after melting from the snow source to the rivers.

We here report the discovery of a gold dental ligature from the late 15 th century, at the Convent of Santa Clara-a-Velha, in the city of Coimbra, Portugal. A medieval Clare's nun presented the left upper lateral incisor splinted to the canine, since the others three incisors were lost, most probably due to an aggressive periodontal disease. The convent is associated with the medieval upper class, which was well known for its consumption of high levels of sugar. There is a higher prevalence of caries in comparison to other Portuguese skeletal samples of the same time period, as well as a high prevalence of periodontal disease. Thus far, this is one of the earliest findings of dental treatment in Europe.

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

Only few medicine books in Norrøn language have survived till today. Concerning Norway and Iceland, just seven fragments of manuscripts are known to us. The oldest manuscript has been dated at about the 13th century, the youngest, which was found in Ireland, at about the time between 1500 and 1550. In medieval times, genuine Scandinavian medical literature did not exist. All seven manuscripts are connected with Continental European sources that are derived from monastic medicine and classical antiquity. The names of Galen, Hippocrates of Kos and Dioscorides are mentioned in some of the texts. Obviously, Norway and Iceland were the recipients of an intensive knowledge transfer from the South via Denmark to the North. Henrik Harpestraeng's book of herbs and the well-known 'Macer floridus' (11th century) are the main sources of the Norrøn manuscripts that are highly related to each other. The text and its variations was made use of during a long period of time and it was widely distributed. A diplomatic edition of the oldest fragment, manuscript AM 655 XXX, and a translation into modern German are the core of the article.

Diseased, maimed, mutilated: categorizations of disability and an ugly law in late nineteenth-century Chicago.

PubMed

Coco, Adrienne Phelps

2010-01-01

The article places Chicago's "ugly" law—an 1881 municipal ordinance that fined "any person who is diseased, maimed, mutilated or in any way deformed so as to be an unsightly or disgusting object" for appearing in public—within the context of late nineteenth-century imaginings of disability. Drawing on the framework of disability studies, this paper demonstrates that nineteenth-century understandings of disability had little to do with the impairments of individuals but instead were tied to the status of the person with the disability. Examining the role of disabled people as workers, as bodies and as charity recipients reveals the hierarchies of disability in late nineteenth-century Chicago and demonstrates who the ugly law intended to restrict and, just as importantly, who it did not. While the law appears to be a blanket indictment of all physically disabled people, multiple sources indicate that the public expected disabled veterans, workers, and freak show performers to occupy the public realm; they therefore cannot be the intended objects of the ordinance. Instead, Chicago's ugly law was one of many pieces of legislation enacted in the wake of the panic of 1873 that attempted to eradicate street begging in general by specifically targeting beggars with disabilities.

This article covers a methodology for evaluating the effectiveness of cleaning two Russian icons. The icons belong to a group of five from the same iconographic school, dating from the 16th to 17th centuries. An integrated and complementary approach to varnish and overpaint removal involved microscopic techniques (optical and scanning electron microscopy) and colorimetry (CIE L*a*b* system). The materials and techniques used in these icons have been characterized previously. Cleaning revealed extensive overpainting that had not only dramatically changed the original appearance, but also the meaning and attribution of one of the two icons. The analyses carried out were useful in determining the extent of the overpainting and led to a better assessment of the results and effectiveness of the restoration. (c) 2009 Wiley-Liss, Inc.

Kölnei, Lívia

2009-01-01

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

Lick Observatory, California, and 20th Century Leadership in Optical Astronomy

Miller, Joseph

With the establishment of the Lick Observatory on Mt. Hamilton in California in 1888 it was immediately established that an observatory located on a relatively high site far from city lights was a far superior location for optical astronomy than the previously common city locations. A few years after its beginning, astronomers at Lick convincingly demonstrated the clear advantage of the reflecting telescope for astrophysical research. Not only was a reflector achromatic over all wavelengths, but it could be made with a small focal ratio that provided high photographic speed. Furthermore, since light did not pass through the optic and it could be supported from behind, it could easily be made in large sizes. Over the first half of the 20^th century the establishment of the Mt. Wilson and Palomar Observatories expanded California's dominance in optical astronomy. Also with the new larger telescopes came major progress in the in design of focal plane instrumentation that allowed these telescopes to be superb tools for astrophysical research. The California observatories of the 20th century were largely independent of Federal funding for operations. Their facilities were were maintained and mostly used by their permanent staffs. This led to a style of doing forefront research that was highly effective, as both long-term survey-type programs and more speculative investigations with less-clear payoffs at the outset could be supported. Also the, the close connection of the scientists doing the research to the development of the telescopes and instruments they used for their research conferred advantages. At present, this style of doing astronomical observational research is a relatively small fraction of all this kind of research. At the end of the 20^th century the California pioneering advancement in ground-based optical astronomy was repeated with the creation of the Keck Observatory.

Habison, Peter

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

Rolling-element bearings in China: From ancient times to the 20th century

NASA Astrophysics Data System (ADS)

Sun, Lie; Li, Ang

2016-03-01

The development of rolling-element bearings in China has spanned a long period. Based on several typical and important cases, the present article reconstructs the history of rolling-element bearings in China by dividing it into four stages according to the various characteristics of the bearings. The first stage represents the origin of rolling bearings in China, which remains controversial because of several suspected races and cages that were likely the components of bearings more than a millennium ago. At the second stage, a type of simple roller bearing was used for astronomical instruments not later than the 13th century based on clear philological and physical evidence. A similar bearing was also applied to an abridged armillary in the 17th century. Another type of spherical thrust bearings with rolling elements, which is a key component of a traditional Chinese windmill, could support a rotating shaft that moves rotationally and at an angle. At the third stage, the Chinese began studying and using the so-called Europeanstyle bearing since the 17th century. Moreover, over the last 100 years, the modern rolling bearing industry was gradually established in China, particularly because of the technology transfer from the Soviet Union in the 1950s. At the fourth stage, the Chinese government initiated the relatively rapid development of bearing technology. The government launched the "bearing movement" from the 1950s to the 1960s to establish the modern bearing industry and to promote rolling bearings as replacement for traditional sliding bearings. Furthermore, a number of large professional factories and institutions in China have continually introduced advanced technology and equipment. At present, these companies and institutions play a significant role in the international bearing industry.

The positive phase of the El Niño-Southern Oscillation (ENSO) increases global mean temperature, and contributes to a negative phase of the Southern Annular Mode (SAM), the dominant mode of climate variability in the Southern Hemisphere. This interannual relationship of a high global mean temperature associated with a negative SAM, however, is opposite to the relationship between their trends under greenhouse warming. We show that over much of the 20th century this relationship undergoes multidecadal fluctuations depending on the intensity of ENSO. During the period 1925–1955, subdued ENSO activities weakened the relationship. However, a similar weakening has occurred since the late 1970s despite the strong ENSO. We demonstrate that this recent weakening is induced by climate change in the Southern Hemisphere. Our result highlights a rare situation in which climate change signals emerge against an opposing property of interannual variability, underscoring the robustness of the recent climate change.

During most of the 20th century, precipitation has been continuously measured by means of the so-called "pluviographs", i.e. rain gauges including a mechanical apparatus for continuously recording the depth of water from precipitation on specific strip charts, usually on a weekly basis. The signal recorded on such strips was visually examined by trained personnel on a regular basis, in order to extract the daily precipitation totals and the maximum precipitation intensities over short periods (from a few minutes to hours). The rest of the high-resolution information contained in the signal was usually not extracted, except for specific cases. A systematic recovering of the entire information at high temporal resolution contained in these precipitation signals would provide a fundamental database to improve the characterization of historical rainfall climatology during the previous century. The Department of Land Engineering of the University of Cagliari has recently developed and tested an automatic software, based on image analysis techniques, which is able to acquire the scanned images of the pluviograph strip charts, to automatically digitise the signal and to produce a digital database of continuous precipitation records at the highest possible temporal resolution, i.e. 5 to 10 minutes. Along with that, a significant amount of daily precipitation totals from the late 19th and the 20th century, either elaborated from pluviograph strip charts or simply derived from bucket rain gauges, still exists in paper form, but it has never been digitalized. Within a project partly-funded by the Operational Programme of the European Union "Italia-Francia Marittimo", the Regional Environmental Protection Agency of Sardinia and the University of Cagliari will recover both the high-resolution rainfall signals and the older time series of daily totals recorded by a large number of pluviographs belonging to the historical monitoring networks of the island of Sardinia.

New proxy records of past climate provide valuable data essential to enhance spatial and temporal coverage of the global paleoclimate record - the context against which ongoing climate change and climate-model forcing is examined and evaluated. We present a new 650-year record of past summer temperatures in southeastern (SE) Europe derived from tree-ring maximum-latewood-density (MXD) data measured from Bosnian pine (Pinus heldreichii) growing at high elevations in the Pirin Mountains, Bulgaria (PRN). The PRN collection is well-replicated, with 64 trees contributing MXD series ranging in length from 113 to 865 years (median series length = 480 years) spanning the years 1143-2009. The PRN chronology shows a significant (p < 0.05) relationship with summer (JAS) temperatures across a broad geographical area of SE Europe, including the entire Balkan peninsula, southern Italy, and southwestern Anatolia. Our temperature reconstruction, produced by multiple regression utilizing lagged predictors and calibrated against Sofia, Bulgaria meteorological observations, explains nearly 60% of target variance and reveals variability across decadal, centennial, and longer timescales over the 1350-2009 reconstruction interval. Relative to the instrumental 1900-1980 mean, our record shows multidecadal cool anomalies spanning the first half of the 19th century and the late 17th century, and warm periods spanning the 18th century, 16th and early-to-mid 17th centuries, and late 14th to early 15th century. A comparison of the PRN reconstruction with existing reconstructions of Northern Hemisphere temperatures reveal intervals of asynchrony between local and hemisphere-scale decadal temperature variability, with marked asynchrony in the late 16th-early 17th centuries, and unprecedented asynchrony in the late 20th-to early 21st century.

Wesleyan Perfectionism in Revivals of the 19th and 20th Centuries at Wheaton College and Its Impact on Institutional Identity

By the end of the 20th century, a modern-day clarion call echoed throughout the Christian collegiate community for religious institutions to divert the trend of secularization and to recover their Christian identity. This study, rather than addressing recovery, explores the distinctive, enduring elements of Wheaton College, a midwestern Christian…

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

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

Secular temperature trends for the southern Rocky Mountains over the last five centuries

Pre-instrumental surface temperature variability in the Southwestern United States has traditionally been reconstructed using variations in the annual ring widths of high altitude trees that live near a growth-limiting isotherm. A number of studies have suggested that the response of some trees to temperature variations is non-stationary, warranting the development of alternative approaches towards reconstructing past regional temperature variability. Here we present a five-century temperature reconstruction for a high-altitude site in the Rocky Mountains derived from the oxygen isotopic composition of cellulose (δ18Oc) from Bristlecone Pine trees. The record is independent of the co-located growth-based reconstruction while providing the same temporal resolution and absolute age constraints. The empirical correlation between δ18Oc and instrumental temperatures is used to produce a temperature transfer function. A forward-model for cellulose isotope variations, driven by meteorological data and output from an isotope-enabled General Circulation Model, is used to evaluate the processes that propagate the temperature signal to the proxy. The cellulose record documents persistent multidecadal variations in δ18Oc that are attributable to temperature shifts on the order of 1°C but no sustained monotonic rise in temperature or a step-like increase since the late 19th century. The isotope-based temperature history is consistent with both regional wood density-based temperature estimates and some sparse early instrumental records.

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

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

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.
