  1. Estudio bibliométrico de la obra de los naturalistas costarricenses Anastasio Alfaro y Henri Pittier en publicaciones periódicas costarricenses entre 1887 y 1946

    Esteban González Pérez

    2011-01-01

    Full Text Available Este trabajo analiza la productividad de los naturalistas Anastasio Alfaro y Henri Pittier en un período de 59 años de los cuales entre ambos autores publicaron 316 artículos en diversas fuentes costarricenses. A estos artículos se les aplicaron varios indicadores métricos tales como productividad y colaboración de los autores, zonas de Bradford y vida media. Además se analizaron las palabras claves para identificar las áreas en que publicaron mayoritariamente. Se concluye que estos dos autores se mantuvieron muy activos en sus años de investigación, considerados grandes productores según el indice de productividad de Lotka y con una colaboración muy escasa por parte de otros autores en sus publicaciones. Además, que sus aportes a la memoria histórica de Costa Rica, en las ciencias biológicas son de gran importancia.

  2. The effect of the tropical cloud (fog) forest on the spatial distribution of cesium-137 in soils in the Henri Pittier National Park (Edo, Aragua, Venezuela)

    LaBrecque, J.J.; Rosales, P.A.; Cordoves, P.R.

    2002-01-01

    Soils were collected at different elevations (m.a.s.l.) near the two roadways, that pass through the Henri Pittier National Park (Edo, Aragua, Venezuela) in order to determine the distribution of the concentrations of the 137 Cs fallout and its relation to the tropical cloud forest. Duplicate samples were taken at most elevations between 2-5 cm below the soil surface to confirm that the samples were representative of the area. In many cases, it was difficult or impossible to locate areas that were undisturbed by man or nature. The 137 Cs (Bq/kg) content was determined by conventional high resolution gamma ray spectroscopy employing a standard comparison method. The background of the 137 Cs fallout in soils, below the cloud (fog) baseline was calculated to be about 5 Bq/kg on both the south (land) side and north (ocean) side for both roadways. The concentrations of 137 Cs (Bq/kg) were between 2-3 times higher at the baseline of the cloud (fog) on both sides of the mountain range. The 137 Cs values at the highest elevations (1105 and 1625 m.a.s.l.) near the roadways were about 5-6 times higher than the determined background levels. Our estimates of the baseline of the cloud (fog) are in good agreement with other visual observations. It was concluded that the distribution of 137 Cs in soils in cloud forests can be employed to estimate the baseline and the concentrations of 137 Cs fallout can be related to the relative density of the cloud (fog) when it was deposited.

  8. Henry Gray's Anatomy.

    Pearce, J M S

    2009-04-01

    Little is generally known of Henry Gray, the author of Gray's Anatomy, and even less of his colleague Henry Vandyke Carter, who played a vital role in the dissections and illustrations leading to the production of the first volume in 1859. This essay attempts to sketch briefly the salient, know aspects of these two men and their divergent careers. It traces succinctly the subsequent fate of the unique anatomy book that has influenced and instructed almost every student of medicine. (c) 2009 Wiley-Liss, Inc.

  9. HENRY'S "HAND OF GOD"

    Željko Kaluđerović

    2014-04-01

    Full Text Available In this paper the author discusses the views and statements of the French football player Thierry Henry he gave after his illegal play during the playoff match between France and the Republic of Ireland to claim one of the final spots in the World Cup 2010 in South Africa. First, by controlling the ball with his hand before passing it on for the goal Henry has shown disregard for the constitutive rules of football. Then, by stating that he is "not a referee" he demonstrated that for some players rules are not inherent to football and that they can be relativized, given that for them winning is the goal of the highest ontological status. Furthermore, he has rejected the rules of sportsmanship, thus expressing his opinion that the opponents are just obstacles which have to be removed in order to achieve your goals. Henry's action has disrupted major moral values, such as justice, honesty, responsibility and beneficence. The rules of fair play have totally been ignored both in Henry's action and in the Football Association of France's unwillingness to comment on whether a replay should take place. They have ignored one of the basic principles stated in the "Declaration of the International Fair Play Committee", according to which, fair play is much more than playing to the rules of the game; it's about the attitude of the sportsperson. It's about respecting your opponent and preserving his or her physical and psychological integrity. Finally, the author believes that the rules, moral values and fair play in football are required for this game to become actually possible to play

    2015-12-01

    Full Text Available In this article I make an inspection of Henry Morton Stanley’s persona through its representation on the American press and the memoirs of his second expedition to Central Africa, Through the Dark Continent. The objective is to make a reflection on the massive means of communication as a tool in the process of construction of a “Victorian hero” and as an historical source. I seek to inquire the persona that was built out of Stanley, made for the popular thorough examination that, in a single lifetime, changed from considered him infamous to exemplary and vice versa.

  12. Henry Gray, plagiarist.

    Richardson, Ruth

    2016-03-01

    The first edition of Anatomy Descriptive and Surgical (1858) was greeted with accolades, but also provoked serious controversy concerning Henry Gray's failure to acknowledge the work of earlier anatomists. A review in the Medical Times (1859) accused Gray of intellectual theft. The journal took the unusual step of substantiating its indictment by publishing twenty parallel texts from Gray and from a pre-existing textbook, Quain's Anatomy. At the recent "Vesalius Continuum" conference in Zakynthos, Greece (2014) Professor Brion Benninger disputed the theft by announcing from the floor the results of a computer analysis of both texts, which he reported exonerated Gray by revealing no evidence of plagiarism. The analysis has not been forthcoming, however, despite requests. Here the historian of Gray's Anatomy supplements the argument set out in the Medical Times 150 years ago with data suggesting unwelcome personality traits in Henry Gray, and demonstrating the utility of others' work to his professional advancement. Fair dealing in the world of anatomy and indeed the genuineness of the lustre of medical fame are important matters, but whether quantitative evidence has anything to add to the discussion concerning Gray's probity can be assessed only if Benninger makes public his computer analysis. © 2015 Wiley Periodicals, Inc.

  13. Henry David Thoreau's Spiritual World

    马云

    2013-01-01

    Henry David Thoreau was wholeheartedly in love with nature and he devoted almost all his life time to observation, appreciation and study of nature. Thus he formed a deep understanding of nature. In 1845, Thoreau began a two-year and two-month residence at Walden Pond. His life was lonely but full of fragrance. He wanted to live meaningfully, confront the essential facts of life and live a simple life. Based on the review of the literature related to this topic, this paper aims to study Henry David Thoreau’s spiritual world, especially reflected in his famous book-Walden.

  18. Obituary: Henry Emil Kandrup, 1955-2003

    Merritt, David; Gottesman, Stephen T.

    2004-12-01

    Henry Emil Kandrup died on 18 October 2003 at his home in Gainesville Florida. Henry was a theoretical astrophysicist specializing in the application of chaotic dynamics to stellar systems. At the time of his death, Henry was a Professor at the University of Florida where he had taught for 13 years. Henry was born in Manhasset, New York on July 24, 1955 and spent most of his childhood in Great Neck. His parents, Jytte and Fred, were immigrants from Denmark where his father had worked as a silver smith. Henry was a precocious child, skipping both third and fifth grades. With the help of Sidney Spivack, a professor of sociology at Columbia University, his parents enrolled Henry in the Brooks Preparatory School in Andover, Massachusetts. After graduating at age 16, Henry enrolled at Cornell, transferring to Princeton the following year. Henry's parents adored their only child and worked hard to provide him with intellectual opportunities. Henry became an accomplished musician (organ, piano, French horn) and linguist (English, Danish, German) and was a passionate devotee of opera and ballet. Henry received his PhD in 1980 from the University of Chicago, where his thesis advisor was James Ipser. He taught at Oakland University in Michigan and Syracuse University in New York before coming to the University of Florida in 1990. Henry was sui generis. He shunned conventionality in his personal appearance and in his public demeanor, and always chose forthrightness and candor over polite silence. But to those of us who knew Henry well, his bluntness was a reflection of his intellectual consistency. Henry always said exactly what he thought, both in his published work and his public presentations, and never compromised himself for the sake of appearances. Nothing that he said or wrote was less than fully thought out. Henry's PhD thesis was entitled "Stochastic Problems in Stellar Dynamics," and most of his subsequent research was in this field. Motion in stellar systems can be

  19. Joseph Henry's Conception of Scientific Knowledge

    Theerman, Paul

    1997-04-01

    Joseph Henry, America's premier physicist and physics teacher in the mid-nineteenth century, had decided views of scientific knowledge. These were expressed in two ways. First of all, scientific knowledge led to moral betterment. Thus the study of science was a morally good thing. This was not only because it led to the contemplation of God's creation, which was a standard reason justifying the study of science dating from the Scientific Revolution and even earlier. More importantly, the study of science itself was a moral discipline, imparting to scientists the habits and virtues of truthfulness, respect for others, care and diligence, and the discernment of meaningful patterns from experience. The moral ideals of science were expressed most strongly in Henry's upholding the international "Republic of Science"; conversely, cheapening science was a sign of moral failure. Second, for Henry and his generation, science provided a path to sure truth, separate from falsehood of both the politics and the quackery that characterized mid-century public life. Henry promoted this in his championing of the Smithsonian Institution a scientific establishment, against the ideas of others who wanted to make it a literary establishment or a training school for teachers. For Henry, the Smithsonian's scientific reputation would be established by relying on careful peer review in its publications, and supporting established scientists to write authoritative popular works. The purpose of both these activities was to raise the profile of science in the United States and further establish science and the scientific method as a guide to public life.

  6. Contaminant Monitoring Strategy for Henrys Lake, Idaho

    John S. Irving; R. P. Breckenridge

    1992-12-01

    Henrys Lake, located in southeastern Idaho, is a large, shallow lake (6,600 acres, {approx} 17.1 feet maximum depth) located at 6,472 feet elevation in Fremont Co., Idaho at the headwaters of the Henrys Fork of the Snake River. The upper watershed is comprised of high mountains of the Targhee National Forest and the lakeshore is surrounded by extensive flats and wetlands, which are mostly privately owned. The lake has been dammed since 1922, and the upper 12 feet of the lake waters are allocated for downriver use. Henrys Lake is a naturally productive lake supporting a nationally recognized ''Blue Ribbon'' trout fishery. There is concern that increasing housing development and cattle grazing may accelerate eutrophication and result in winter and early spring fish kills. There has not been a recent thorough assessment of lake water quality. However, the Department of Environmental Quality (DEQ) is currently conducting a study of water quality on Henrys Lake and tributary streams. Septic systems and lawn runoff from housing developments on the north, west, and southwest shores could potentially contribute to the nutrient enrichment of the lake. Many houses are on steep hillsides where runoff from lawns, driveways, etc. drain into wetland flats along the lake or directly into the lake. In addition, seepage from septic systems (drainfields) drain directly into the wetlands enter groundwater areas that seep into the lake. Cattle grazing along the lake margin, riparian areas, and uplands is likely accelerating erosion and nutrient enrichment. Also, cattle grazing along riparian areas likely adds to nutrient enrichment of the lake through subsurface flow and direct runoff. Stream bank and lakeshore erosion may also accelerate eutrophication by increasing the sedimentation of the lake. Approximately nine streams feed the lake (see map), but flows are often severely reduced or completely eliminated due to irrigation diversion. In addition, subsurface

    Zero tolerance policies have been increasingly popular in both education and business. Henri Fayol was the one of the earliest and influential thinkers in modern management theory. He defined management as a body of knowledge and defined his 14 administrative principles. It is an interesting exercise to apply Fayol’s teachings to the theory of zero tolerance and attempt to determine what Fayol would think of this new management technique.

    Full Text Available Born in Germany and descendant of a wealthy banking family, Henry C. Wallich emigrated to the United States like others of Jewish ancestry who fled during the 1930s. A professor of money and banking at Yale for two decades, Wallich capped his career as a Governor of the Federal Reserve. During the stagflation of the late 1960s, Wallich, a dissenter, tirelessly advocated tighter monetary policy to stem inflation. Always a scholar, Wallich published extensively; he also served as the Fed’s public spokesman. Owing to his Harvard doctorate and his eminence as an economist, Wallich knew everyone worth knowing in the economics profession.

    This paper recalls the history of the Becquerel family, the fascinating time of the discovery of radioactivity as well as some important related research published before the radium age. Henri Becquerel was the third in the line of a family of scientists which extended over more than a hundred years. Following in the footsteps of his father and grandfather gave him a thorough grounding in scientific research methods. Science at the turn of the century was very exciting, the discovery of X rays had just been announced and scientists everywhere were hoping to discover new phenomena. (author)

  12. Henry Fuseli’s Alternative Classicism

    Martin Myrone

    2015-12-01

    Full Text Available The review considers Andrei Pop’s Antiquity, Theatre & The Painting of Henry Fuseli. This argues for the history painter and writer Fuseli as an exemplary ‘Neopagan’, a term coined by Pop to refer to the new sense of cultural pluralism and historical relativism which emerged in Europe after the discovery of the remains of Pompeii and Herculaneum in 1748. While this perspective offers a fresh view of the artist, relating him to the emergence of modernity, and illuminates some important aspects of his work, the reviewer also suggests that the monographic focus risks re-asserting a sense of Fuseli’s exceptionalism.

  13. Henry James – Modern Theoretician of Narration

    Alexandra - Denisa IGNA

    2013-01-01

    Full Text Available Henry James, properly named world writer, was one of the first modern novelists, with an exigent writing conscience. The American writer subverted the prejudgement of the omniscient author in favour of the narration which is centred on the characters’ point of view, thus modernising the novel before V. Woolf, Huxley, Thomas Mann, or in our case Camil Petrescu and G. Călinescu. Some bio-bibliographical information familiarises the reader with the life and work of this writer. The larger part of the article is dedicated to a case study of the novel with the metaphorical title: The Figure in the Carpet, where Henry James tries to illustrate in an artistic manner his conception regarding the profundity and ineffability of the literary creation. The conclusion which the author reaches, alternating the familiar plan of the relationship between a married couple with the esthetical plan, is that the relationship between writer and his work represents an act of fully intimacy, just like a ceremony that takes place in the wedding night

  14. Henry VIII, McLeod syndrome and Jacquetta's curse.

    Stride, P; Lopes Floro, K

    2013-01-01

    The mental decline of King Henry VIII from being a jovial, charismatic and athletic young man into an increasingly paranoid, brutal tyrant in later life, ever more concerned at his lack of one or more male heirs, has attracted many medical diagnostic theories. Previous hypotheses have included diabetes, syphilis and hypothyroidism, among others. However, these inadequately explain Henry's failure to produce a male heir, despite multiple pairings. The latest postulated diagnoses for Henry are the coexistence of both Kell blood group antigenicity (possibly inherited from Jacquetta Woodville, Henry's maternal great grandmother) causing related impaired fertility, and McLeod syndrome, causing psychotic changes. As the mutated McLeod protein of the syndrome significantly reduces the expression, effectively inactivating the Kell antigen, we critically review this theory, examining in detail the pathophysiology of these conditions and assessing the genealogy of Henry VIII and its effect in subsequent generations.

  15. Obituary: Henry Albers (1925-2009)

    Chromey, Fred

    2011-12-01

    Henry Albers, professor of astronomy at Vassar College for over thirty years, died March 29, 2009, in Fairhope, Alabama. For his work at Vassar, where he held the Maria Mitchell Chair, Albers received the first Maria Mitchell Women in Science Award for his inspiration of women astronomers. He said "In the final analysis it is the students who bring the joy into teaching." As a professional astronomer, Albers did observational work on Galactic structure in the southern Milky Way, and on the structure of the Magellanic Clouds. In retirement, Albers published Maria Mitchell - A Life in Journals and Letters, the firsthand account of America's first woman astronomer. Albers's research was on photographic near-infrared spectroscopy of red giant stars in the southern Milky Way, some proper motion studies, and on the structure of the Magellanic Clouds. A series of seven NSF grants supported his six trips to Chile to make spectroscopic observations, as well as his sabbatical collaborations at Minnesota, Leiden, and the Royal Observatory in Edinburgh. Henry Albers arrived at Vassar in 1958, to find an astronomy program that had been recently absorbed by the physics department, and that was suffering neglect after the retirement of Maud Makemson. For the next 31 years, with incredible energy -- he sometimes taught seven courses a year -- he built the astronomy program into one double in size (from one to two tenure lines), whose th century facilities have been replaced with a st century observatory. For a remarkable stretch of 20-some-years, Albers and physicist Bob Stearns, with considerable grace, alternated chairmanship of the joint department of physics and astronomy. Henry Albers was a devoted citizen of Vassar College and an enthusiastic participant in the process of faculty governance at that institution. He would have been the first to concede that his enthusiasm was sometimes excessive, and that his contributions at faculty meetings occasionally failed to move the

    2014-08-01

    The year 2012 marked the centenary of the death of Henri Poincaré (Nancy, 1854-Paris, 1912), and through the agency of the Henri-Poincaré Institute in Paris, the Henri-Poincaré Archives in Nancy and The London Mathematical Society, brought with it several exhibitions and meetings commemorating one of the greatest minds in contemporary times. Often referred to as the last polymath, Poincaré embraced multiple branches of mathematics, theoretical physics and celestial mechanics, and made significant contributions to philosophy of science (Heinzmann & Stump, Henri Poincaré, 2013). He wrote 25 textbooks and monographs, 500-plus articles, and was deeply involved in the organization and administration of science at both the national and international levels.1

    Full Text Available In his otherwise excellent book, A History of Archaeological Thought, Trigger (1989: 156 makes only one passing reference in a half-sentence to the central figure in the development of Paleolithic prehistory in the first half of the 20th century -- and manages to get his name wrong, confusing Henri Breuil with his long-time, close colleague, Hugo Obenrnaie . Thirty years after his death, Breuil's role in the history of Old World prehistory required more serious consideration.

The following is a brief summary of some of my conclusions.

  1. Henry Head and the Theatre of Reverie

    Tiffany Watt-Smith

    2011-04-01

    Full Text Available In 1903, the neurologist Henry Head (1861-1940 embarked on a painful self-experiment, in which he severed the radial nerve of his left arm, and then charted the gradual and faltering return of sensitivity to the limb over the next four and a half years. To directly experience his own sensations, Head entered into a trance-like state of distraction or reverie he called a ‘negative attitude of attention’. This article explores Head’s peculiar technique for looking within, and argues that while introspection was an established strategy in psychological laboratories, Head’s reverie also resonated with techniques associated with actors and theatrical audiences during this period. Viewing psychological self-experimentation through the lens of theatre, this article makes visible aspects of Head’s embodied, affective laboratory encounters, often obscured in accounts of his experiment. At the same time, it proposes that the broader historical and cultural significance of Head’s experiment lies in his attempt to observe himself by producing states of inattention and reverie at will, mental ‘attitudes’ that were themselves the subject of a rapidly evolving debate in scientific and aesthetic circles at the turn of the twentieth century.

  2. Victor Henri: 111 years of his equation.

    Cornish-Bowden, Athel; Mazat, Jean-Pierre; Nicolas, Serge

    2014-12-01

    Victor Henri's great contribution to the understanding of enzyme kinetics and mechanism is not always given the credit that it deserves. In addition, his earlier work in experimental psychology is totally unknown to biochemists, and his later work in spectroscopy and photobiology almost equally so. Applying great rigour to his analysis he succeeded in obtaining a model of enzyme action that explained all of the observations available to him, and he showed why the considerable amount of work done in the preceding decade had not led to understanding. His view was that only physical chemistry could explain the behaviour of enzymes, and that models should be judged in accordance with their capacity not only to explain previously known facts but also to predict new observations against which they could be tested. The kinetic equation usually attributed to Michaelis and Menten was in reality due to him. His thesis of 1903 is now available in English.

  4. “Not a man from England”: assimilating the exotic ‘other’ through performance, from Henry IV to Henry VI

    Penlington, A.

    2010-01-01

    This essay will consider recent shifts in performance representations of England and the exotic ‘other’ in Shakespeare’s Henry IV, Henry V and Henry VI plays. By tracing the texts’ varied representations of non-English Britons and those for whom English is not their mother tongue (such as Owen Glyndwr in 1 Henry IV and Princess Catherine in Henry V), recent criticism has identified that Shakespeare’s narrative portrays the challenges of assimilating ‘otherness’ within English culture. This es...

OBJETIVO Caracterizar los perfiles de los hombres que solicitan tratamiento para la DE en la farmacia, con o sin receta de inhibidores de la fosfodiesterasa tipo 5 (iPDE5. MÉTODOS Entre septiembre y noviembre de 2008 se realizó un estudio observacional, transversal y multicéntrico en farmacias comunitarias de España. De aquellos hombres que solicitaban consejo o tratamiento para la DE, cada investigador reclutó un paciente que tenía receta médica de iPDE5 y otro que acudía sin receta médica. Los farmacéuticos del estudio completaron un cuestionario de datos demográficos, clínicos y conductuales del paciente, incluido el Cuestionario de salud sexual para varones (Sexual Health Inventory for Men. VARIABLES PRINCIPALES Características demográficas y respuestas a los cuestionarios. RESULTADOS 574 farmacéuticos seleccionaron a 1.147 pacientes, de los cuales 1.113 fueron incluidos en el análisis. No se observaron diferencias estadísticas entre los grupos en cuanto al peso, la hipertensión, la diabetes mellitus, la hipercolesterolemia, la dislipidemia, la depresión o el estrés. Tampoco se observaron diferencias estadísticas respecto a la gravedad de la DE (p = 0,7892 ni a la proporción de hombres sin DE en cada grupo (p = 0,5755. En ambos grupos, los pacientes habían presentado síntomas de DE durante una media de veintiséis meses antes de la primera consulta a un profesional sanitario.

    Full Text Available Este ensayo del sabio conservacionista Henri Pittier (1857-1950 que data de 1904 es posiblemente el primer testimonio sobre la excepcional longevidad de los habitantes de la Península de Nicoya, Costa Rica. Fue el estadístico costarricense Carlos Raabe quien llamó mi atención sobre este ensayo cuando en 2007 diversos medios de comunicación del mundo dan a conocer a la, así llamada, “Blue Zone” de Nicoya. La organización National Geographic había acuñado tres años antes en un artículo de su conocida revista el término Blue Zone para designar tres bolsones de súper longevidad en el mundo: Okinawa en Japón, Cerdeña en Italia y Loma Linda en California, EEUU. Más tarde, y a raíz de una ponencia sobre la excepcionalmente baja mortalidad de los nonagenarios costarricenses que presenté en la XXV Conferencia Mundial de la Unión Internacional para el Estudio Científico de la Población (IUSSP en Tours, Francia y tras cuidadoso examen de la evidencia científica, National Geographic incluye a la península de Nicoya como la cuarta Blue Zone del mundo. Henri Pittier se anticipa, entonces, cien años en descubrir la Blue Zone de Nicoya.¿Quién es Henri Pittier?Una rápida búsqueda en Google da cuenta de que el más antiguo y más famoso parque nacional de Venezuela, establecido en 1938, se denomina Henri Pittier en reconocimiento al botánico y geógrafo suizo de ese nombre que se estableció en ese país en 1917 y que publicó en 1926 el “Manual de las Plantas Usuales de Venezuela” una obra clásica reeditada varias veces y utilizada hasta nuestros días. Pittier publicó cerca de 300 obras, entre los que se cuenta otra obra clásica: “Primitia Flora Costaricensis” (1907.

    The use of eponyms in medicine is often discouraged. However, the literary eponym should be an exception as it is not linked with many of the difficulties associated with conventional eponyms and offers descriptive brevity and accuracy. Here, we illustrate the point with Henry V sign, which will be familiar to many who have cared for patients in the terminal stage of illness.

    2014-01-01

    On July 17, 2012, the centenary of Henri Poincaré's death was commemorated; his name being associated with so many fields of knowledge that he was considered as the Last Universalist. In Pure and Applied Mathematics, Physics, Astronomy, Engineering and Philosophy, his works have had a great impact all over the world. Poincaré acquired in his lifetime such a reputation that, both nationally and internationally, his life and career were made the object of various articles in the daily papers not only in France, but also in the USA. Some of his philosophical concepts have even caused sharp controversies in the Press (as we will discover in this book).This work presents an original portrait of Henri Poincaré based on various press cuttings from The New York Times, The San Francisco Sunday Call, The Times, The Sun, The Washington Post that chronicled unknown anecdotes of his life (for example, his first name was actually not Henri, but Henry; he obtained his high school diploma in sciences with a zero in mathem...

  1. Thomas Henry Huxley et la Bible Thomas Henry Huxley and the Bible

    Christophe Duvey

    2009-10-01

    Full Text Available Thomas Henry Huxley devoted several essays to the study of the Bible. This interest can only be accounted for if his ideas on history, religion as well as epistemology are examined. According to him, a struggle between free thought and supernaturalism was culminating during the Victorian era, hence the need for a “New Reformation” which was heir to the ideals of freedom defended by the humanists of the Renaissance. This movement opposed the principles of the supporters of what he called “ecclesiasticism”. The advocates of the “New Reformation” could rely on the progress of modern science, and agnosticism, which Huxley identified with scientific method, became its epistemological foundation. As a result, Huxley thought that the authority of physical science was in conflict with the infallibility of the Scriptures and with the theological arguments which rested on it, and this notably led him to the conclusion that the biblical narrative of the Flood was unhistorical. The naturalisation of the Scriptures seems then logically to follow his philosophical views based on the limits of human knowledge.It appears that it was the question of authority which underlay Huxley’s interest in the Bible. He thought that the authority of the Scriptures must be replaced by that of science.

  2. Obituary: Roy Henry Garstang (1925-2009)

    Malville, J.

    2011-12-01

    Roy Henry Garstang 84 passed away on November 1, 2009 in Boulder Colorado. He was born in Southport, England in September of 1925 to Percy Brocklehurst and Eunice (Gledhill) Garstang. He won a scholarship to Caius College in Cambridge University. Because it was wartime, he could spend only two years at his studies. However, he managed to complete three years of required work during that time, and then spent 1945-46 as a Junior Scientific Officer at the Royal Aircraft Establishment at Farnborough. He received his BA in 1946 from Cambridge, his MA in 1950, and his PhD in Mathematics in 1954, with a thesis: "Atomic Transitions in Astrophysics," working under D. R. Hartree. He also received a ScD from Cambridge in Physics and Chemistry in 1983. He married Ann in August 1959. She and two daughters, Jennifer and Susan, survive him. While still pursuing his PhD, Roy Garstang served as a Research Associate at the Yerkes Observatory, from 1951-1952, working under Subrahmanyan Chandrasekhar. During that time he continued with his own calculations of atomic structure and transition probabilities, although these were not part of Chandra's research interests. After earning his PhD, he went to teach at the University of London, where he also served as the Assistant Director of the University of London Observatory (1959-1964). He was editor of "The Observatory" Magazine form 1953-1960. The continuing theme of this research was to help meet the needs of astrophysicists for atomic data. In 1964, he left England for the United States, where he joined the faculty at the University of Colorado, Boulder, where he would remain for the rest of his professional career. It was entirely fitting, considering his interest in performing calculations of interest to astrophysicists, that soon after arriving in Boulder he was appointed Chairman of JILA - Joint Institute for Laboratory Astrophysics (1966-1967). He was Director of the Division of Physics and AstroGeophysics (1979-80), acting

  5. Should bulk cloudwater or fogwater samples obey Henry's law?

    Pandis, Spyros N.; Seinfeld, John H.

    1991-06-01

    Mixing of droplets with different pH that are individually in Henry's law equilibrium with the surrounding atmosphere always results in a bulk mixture that is supersaturated with weak acids like S(IV) and HCOOH, and bases like NH3 with respect to the original atmosphere. High supersaturations result only when the pH of the bulk droplet mixture exceeds the pKa of the species, in which pH range large pH differences among droplets of different sizes lead to large deviations from Henry's law for the bulk mixture. The deviation is shown to depend on the ratio of the arithmetic mean to the harmonic mean of the hydrogen ion concentrations of the droplets with the liquid water content used as weighting factor in the calculation of the means. The theory developed can explain observed discrepancies from Henry's law in atmospheric samples and also other observed phenomena like the reported increase of pH values of bulk aqueous samples during storage.

  7. [From apprenticeship to Nobel Prize: Henri Moissan's fabulous destiny].

    Lafont, O

    2008-01-01

    Born in Paris on September 28, 1852, son of an eastern railways' employee and of a dressmaker, Henri Moissan's secondary schooling in Meaux did not allow him to get access to the sesame diploma "baccalauréat" (GCE). In 1869, he did obtain a special certificate of secondary schooling so that he could become an apprentice in watch making. That could have been the end of the story, but dreadful event for France appeared to have beneficial effects for Moissan. Under the threat of the Prussian army, Moissan's family took refuge near Paris. This gave the young Henri the opportunity to register as a student for the second-class pharmacy diploma, which did not need, at the time, the GCE. Moissan became then a trainee in pharmacy in 1871. Meanwhile, he followed the special schooling of "Ecole de chimie" founded by E. Frémy, and then joined the laboratory of Dehérain at the Museum, where he worked in plant physiology. He finally obtained the famous "baccalauréat" (GCE) and could register as a student in first-class pharmacy. He became a pharmacist as well as a doctor in sciences. In 1883, Moissan was named professor at the school of pharmacy in Paris. In 1886, he isolated fluorine by electrolysis of fluorhydric acid, in the presence of potassium fluoride, at a low temperature. He then studied diamond synthesis and gave a start to high temperature chemistry, designing his famous furnace. These findings and many others allowed Moissan to rise to membership in many learned academies around the world. Crowning achievement, Moissan won the Nobel Prize in 1906. A man of culture, collector of autographs and paintings, he died in 1907. Nothing of that would have been possible if there had not been a second-class pharmacist diploma. The history of Henri Moissan is one of a rise from apprenticeship to the Nobel Prize.

    Edward Henry Sieveking, eminent London physician of Victorian times, is best known as the speaker at the historic meeting at which the chairman, Sir Charles Locock, seem to overshadow him in announcing the introduction of bromide--the first effective anti-convulsant. But in fact Sieveking had announced a most important conceptual advance in epileptology--the demise of "essential epilepsy". In addition his book, published soon after and based upon his lecture, is an important historical resumé of Victorian era concepts and management of epilepsy. His important contributions to the understanding and management of this condition are discussed herein.

  11. Henri Ey's neojacksonism and the psychopathology of disintegrated mind.

    Farina, Benedetto; Ceccarelli, Maurizio; Di Giannantonio, Massimo

    2005-01-01

    The French psychiatrist Henri Ey developed his organo-dynamic theory of the mind function and consciousness 50 years ago incorporating Hughling Jackson's thinking, along with psychiatric and philosophical theorizations by Janet and Bergson. This model has not received the attention it deserved, but recent advances in neuroscience rekindled interest for Ey's theory. By overcoming the Cartesian mind-body dualism and treating the mind-body unit as an inseparable whole, this model opens the way for the integrated treatment of mental disorders. Ey's conceptualization of consciousness as being simultaneously both synchronous and diachronic anticipates current theories of consciousness (Damasio, Edelman, Mesulam).

  12. Evaluating Henry's law constant of N-nitrosodimethylamine (NDMA).

    Haruta, Shinsuke; Jiao, Wentao; Chen, Weiping; Chang, Andrew C; Gan, Jay

    2011-01-01

    N-Nitrosodimethylamine (NDMA), a potential carcinogen, may contaminate the groundwater when the reclaimed wastewater is used for irrigation and groundwater recharge. Henry's law constant is a critical parameter to assess the fate and transport of reclaimed wastewater-borne NDMA in the soil profile. We conducted a laboratory experiment in which the change of NDMA concentration in water exposed to the atmosphere was measured with respect to time and, based on the data, obtained the dimensionless Henry's law constant (K(H)') of NDMA, at 1.0 x 10(-4). The K(H)' suggests that NDMA has a relatively high potential to volatilize in the field where NDMA-containing wastewater is used for irrigation and the volatilization loss may be a significant pathway of NDMA transport. The experiment was based on the two boundary-layer approach of mass transfer at the atmosphere-water interface. It is an expedient method to delineate K(H)' for volatile or semi-volatile compounds present in water at low concentrations.

  13. VoxHenry: FFT-Accelerated Inductance Extraction for Voxelized Geometries

    Yucel, Abdulkadir C.

    2018-01-18

    VoxHenry, a fast Fourier transform (FFT)-accelerated integral-equation-based simulator for extracting frequency-dependent inductances and resistances of structures discretized by voxels, is presented. VoxHenry shares many features with the popular inductance extractor, FastHenry. Just like FastHenry, VoxHenry solves a combination of the electric volume integral equation and the current continuity equation, but with three distinctions that make VoxHenry suitable and extremely efficient for analyzing voxelized geometries: 1) it leverages a carefully selected set of piecewise-constant and piecewise-linear basis functions; 2) it exploits FFTs to accelerate the matrix-vector multiplications during the iterative solution of system of equations; and 3) it employs a sparse preconditioner to ensure the rapid convergence of iterative solution. VoxHenry is capable of accurately computing frequency-dependent inductances and resistances of arbitrarily shaped and large-scale structures on a desktop computer. The accuracy, efficiency, and applicability of VoxHenry are demonstrated through inductance analysis of various structures, including square and circular coils as well as arrays of RF inductors (situated over ground planes).

    Full Text Available Henri Pirenne (1862-1935 is generally recognised as one of the most influential European historians of the late nineteenth- and early twentieth-century. The combination of his scholarly activity with the social mission that he set himself earned him an extraordinarily successful career and a double reputation: at least in Belgium, he was regarded not only as a ‘father of history’, but also as great citizen. Although his influence was unmistakably large, there is no consensus about the existence or the nature of a ‘Pirennian persona’. He combined the ideal collection of skills, values and standards required of historians with very specific personal characteristics. At the same time he was inextricably linked to a certain era and a certain Belgium that died with him.

Historicus en man van de wereld. Henri Pirenne (1862-1935 wordt beschouwd als één van de meest invloedrijke Europese geschiedschrijvers van de laatnegentiende en vroegtwintigste eeuw. Het verband tussen zijn wetenschappelijke activiteit en de maatschappelijke taak die hij voor zichzelf zag weggelegd, leverde hem een uitzonderlijk succesvolle carrière en een dubbele reputatie op. Pirenne staat, althans in België, immers niet alleen geboekstaafd als een ‘vader van de geschiedenis’, maar ook als een groot staatsburger. Hoewel de invloed van Pirenne onmiskenbaar groot is geweest, is er geen consensus over het bestaan of de aard van een ‘pirenniaanse persona’. Hij combineerde het ideaalpakket van vaardigheden, normen en waarden die historici werden geacht te bezitten met zeer specifieke karaktereigenschappen. Tegelijk was hij onlosmakelijk verknoopt met een zeker tijdsgewricht en een zeker België, dat samen met hem ter ziele ging. Pirenne stond dan ook niet zozeer model voor een nieuw

    Henri de Régnier disait de José-Maria de Heredia qu’il avait fait le lien entre le Parnasse et le symbolisme. Lui-même fit le lien entre le symbolisme et le Parnasse. En 1895, il notait dans son journal intime : « J’ai subi de grandes influences. Aux premiers jours, Mallarmé m’a […] nettoyé l’esprit ; j’en ai été affiné et ankylosé. Puis j’ai subi les contacts plus vivants d’Heredia. » Cette seconde influence contrebalança la première. Régnier fréquenta les samedis de la rue Balzac avec autan...

  19. Thinking in time an introduction to Henri Bergson

    Guerlac, Suzanne

    2006-01-01

    "In recent years, we have grown accustomed to philosophical language that is intensely self-conscious and rhetorically thick, often tragic in tone. It is enlivening to read Bergson, who exerts so little rhetorical pressure while exacting such a substantial effort of thought. . . . Bergson's texts teach the reader to let go of entrenched intellectual habits and to begin to think differently—to think in time. . . . Too much and too little have been said about Bergson. Too much, because of the various appropriations of his thought. Too little, because the work itself has not been carefully studied in recent decades."—from Thinking in TimeHenri Bergson (1859–1941), whose philosophical works emphasized motion, time, and change, won the Nobel Prize for Literature in 1927. His work remains influential, particularly in the realms of philosophy, cultural studies, and new media studies. In Thinking in Time, Suzanne Guerlac provides readers with the conceptual and contextual tools necessary for informed appreciati...

  20. W.E. Henry Symposium compendium: The importance of magnetism in physics and material science

    Carwell, H.

    1997-09-19

    This compendium contains papers presented at the W. E. Henry Symposium, The Importance of Magnetism in Physics and Material Science. The one-day symposium was conducted to recognize the achievements of Dr. Warren Elliot Henry as educator, scientist, and inventor in a career spanning almost 70 years. Dr. Henry, who is 88 years old, attended the symposium. Nobel Laureate, Dr. Glenn Seaborg, a friend and colleague for over 40 years, attended the event and shared his personal reminiscences. Dr. Seaborg is Associate Director-At-Large at the Lawrence Berkeley National Laboratory. The Compendium begins with three papers which demonstrate the ongoing importance of magnetism in physics and material science. Other contributions cover the highlights of Dr. Henry`s career as a researcher, educator, and inventor. Colleagues and former students share insights on the impact of Dr. Henry`s research in the field of magnetism, low temperature physics, and solid state physics; his influence on students as an educator; and his character, intellect and ingenuity, and passion for learning and teaching. They share a glimpse of the environment and times that molded him as a man, and the circumstances under which he made his great achievements despite the many challenges he faced.

  1. Restauration de la statue de Henri IV

    Full Text Available Cette intervention de conservation du bronze de la statue de Henri IV était la première depuis sa création en 1818 : on héritait de la surface originale de l’œuvre altérée par les vicissitudes du temps et les événements historiques traversés. Le protocole de conservation se voulait respectueux de cette authenticité de la patine et a cherché à en laisser les marques tout en apportant une réponse pour contrer la corrosion active de l’alliage. C’est en conformité aux principes de conservation établis par Cesare Brandi, qu’ont été définis le nettoyage sélectif des surfaces et l’application de couches protectives sur le bronze. Par ailleurs, le moment du chantier est un moment privilégié pour observer un monument et mieux connaître son histoire particulière. Ce chantier nous a permis de redécouvrir deux ensembles de boîtes déposées dans l’antre du cheval dans des situations parfois surprenantes.This conservation treatment for the bronze statue of Henri IV is the first since its creation in 1818. While the original surface of the work remains, it has been altered by natural and human forces; including the weathering of the material from exposure to the elements and damage caused by historic events. The conservation protocol is respectful of this authenticity of the surface patina and the marks of damage due to historical events, while developing a treatment plan to counter the active corrosion of the alloy. In keeping with the principles of conservation established by Cesare Brandi, the treatment program defines the selective cleaning of the surface and the application of several layers of a protective coating on the bronze. In addition, the conservation project is an opportunity to carefully study a monument to better understand its unique history. This project allowed us to rediscover two sets of boxes placed inside the cavity of the horse; an unxpected discovery.

  7. Why it was natural for Henri Becquerel to discover natural radioactivity

    Barquins, M.

    2002-01-01

    This article presents the scientific saga of the Becquerel family. 4 generations of Becquerel Antoine-Cesar (1788-1878), Edmond (1820-1891), Henri (1852-1906) and Jean (1878-1953) were involved in scientific activities at the highest level. Henri was awarded the Nobel prize of physics (shared with Pierre and Marie Curie) in 1903 for the discovery of radioactivity. The author shows that the discovery of radioactivity was due to talent, family emulation, genetics and chance. (A.C.)

  10. Henry Beecher's Contributions to the Ethics of Clinical Research.

    Veatch, Robert M

    2016-01-01

    In the 1950s and '60s, Henry Beecher pioneered the discussion of the ethics of clinical research, leading eventually to the publication of the famous New England Journal of Medicine article summarizing 22 research studies that Beecher suggests were unethical. Those studies generally showed a pattern of posing serious risks to subjects without anticipated proportional benefit. Beecher famously claimed that the problem was not that researchers were malicious or evil; rather, he claimed the problem was they manifested thoughtlessness or carelessness. He called for more rigorous self-scrutiny rather than public review.This article argues that Beecher's reliance on conscientious investigators is problematic. In particular, it focuses on benefits and harms to the exclusion of other moral criteria. However, both research subjects and public regulators are also concerned about autonomy and the consent requirement, confidentiality, and fairness in subject selection and research design. The movement in the 1970s toward more public scrutiny was critical, even though Beecher was right in holding that it was not "vicious disregard for subject welfare" that explained unethical protocols.

  11. The enigmatic figure of Dr Henry Maudsley (1835-1918).

    Pantelidou, Maria; Demetriades, Andreas K

    2014-08-01

    In spite of his contribution to psychiatry in 19th century Britain, Henry Maudsley remains a mysterious figure, a man mostly known for his donation to the London County Council for the building of the Maudsley Hospital and for The Maudsley Annual Lecture created in honour of his benevolence. Besides Sir Aubrey Lewis' article in 1951 and Michael Collie's attempt in 1988 to construct a biographical study on Maudsley, there does not seem to be any current endeavour to tell the story of his life, whereas Trevor Turner's contribution to the 2004 Oxford Dictionary of National Biography gives a somewhat scathing but unattributed account of Maudsley's personality. This essay attempts to explore his contributions to the Medico-Psychological Association (MPA), the current Royal College of Psychiatrists, his editorship of the Journal of Mental Health (currently named the British Journal of Psychiatry), his literary contributions and his vision for a psychiatric hospital. This essay is an attempt to demystify his figure and to explore some of the rumours and criticisms surrounding his name and the reasons why so little has been written about him. It is also a venture to unravel his complex personality and his intricate philosophy. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

  12. The Works of Henry Moseley, 1887-1915

    Scerri, Eric

    2013-04-01

    In 1913 Henry Moseley, an unknown young English physicist published an article in the Philosophical Magazine under the title of ``The High Frequency Spectra of the Elements.'' The 10-page article was to have far reaching implications in both chemistry and physics and helped to resolve a major conundrum in the periodic table of the elements. The talk will briefly examine the life and work of Moseley who died tragically while fighting in the trenches of World War I in 1915. The build-up to the discovery of atomic number took several different avenues including contributions from Rutherford and Barkla. However the more direct motivation for Moseley's work, as he readily acknowledged, were the articles of an unknown Dutch econometrician Anton Van den Broek who attempted to improve on Mendeleev's periodic table. Moseley began as a student of Rutherford at Manchester and took a keen interest in the development of research using X-rays following the work of Roentgen, von Laue and Bragg. Although Rutherford was at first reluctant to enter this new field he soon yielded to young Moseley's request and sent him to Leeds for brief training with Bragg. On returning to Manchester, Moseley devised an ingenious apparatus in which a set of metal samples could be rotated so as to become the target for a beam of electrons in order to measure the frequencies of the emitted K X-rays. The first set of such experiments used nine successive elements in the periodic table, from titanium to zinc. Moseley's now immense fame rests with the results of this study as well as a subsequent one which extended the study into a further 30 elements, in addition to the use that his method was put to by himself as well as subsequent chemists and physicists.

  13. [Hypospadia and infertility of Henry II of France (1519-1559)].

    Hatzinger, M; Al-Shajlawi, S; Sohn, M

    2014-03-01

    Henry II (1519-1559) of France was the second son of Francis I (1494-1547) and Claude de France (1498-1524) born in 1519 in St. Germain-en-Laye. After his older brother's and his father's death in 1547, he was anointed the French king in Reims. In 1533 already, as a 14-year-old boy, for reasons of state, he was married to the same aged Catherine de Medici (1519-1589), as her uncle was Pope Clement VII (1478-1534). The marriage remained childless for 11 years since Henry, due to a distinct hypospadia and a completely sexually inexperienced wife was unable to conceive children with her. His existing liaison to Diane de Poitiers (1499-1566) - a 19-year-older maid of honor of his father Francis I from 1537 until his death - influenced his sexual life immensely.The blame for the childless marriage was placed primarily on his wife, as Henry had become father of an illegitimate daughter with a mistress. Catherine then underwent all possible medical and alchemical procedures to finally give birth to the hoped Dauphin. Ironically, her rival for the favor of her husband, Diane de Poitiers was one of her greatest allies. She made clear that the cause lay with Henry and not with his wife. This was confirmed by the added solid physician Jean Fernel (1497-1558). His treatment of Henry and the simultaneous training of the unexperienced Catherine by Diane de Poitiers led to success.The result was the birth of Francis II (1544-1560) in 1544, the first of 10 children in 12 years. Thus, the dynasty was saved. After the death of Henry in a tragic tournament accident in 1559, three of his sons became kings of France. But the line of Valois remained without further descendants and was continued by Henry IV, the first Bourbon king in 1589.

  18. Copper-Mediated Reactions of Nitriles with Nitromethanes: Aza-Henry Reactions and Nitrile Hydrations.

    Kuwabara, Jun; Sawada, Yoshiharu; Yoshimatsu, Mitsuhiro

    2018-02-16

    In this study, the first aza-Henry reaction of nitriles with nitromethane in a CuI/Cs 2 CO 3 /DBU system is described. The process was conveniently and directly used for the synthesis of β-aminonitroalkenes 2a-x and tolerated aryl-, alkyl-, hetaryl-, alkenyl-, and alkynylnitriles. The resulting aminonitroalkenes 2 could be successfully transformed to the corresponding 2-nitroacetophenones, 2-amino-1-halonitroalkenes, 2-alkylaminonitroalkenes, or 3-nitropyridines. In the presence of H 2 O, the aza-Henry reaction turned the reaction path to the nitrile hydration to exclusively yield the amides 3a-s.

  19. Taxing junk food: applying the logic of the Henry tax review to food.

    Bond, Molly E; Williams, Michael J; Crammond, Brad; Loff, Bebe

    2010-10-18

    The recent review of taxation in Australia - the Henry tax review - has recommended that the federal government increase the taxes already levied on tobacco and alcohol. Tobacco and alcohol taxes are put forward as the best way of reducing the social harms caused by the use and misuse of these substances. Junk foods have the same pattern of misuse and the same social costs as tobacco and alcohol. The Henry tax review rejects the idea of taxing fatty foods, and to date the government has not implemented a tax on junk food. We propose that a tax on junk food be implemented as a tool to reduce consumption and address the obesity epidemic.

  15. Pornografia e transgressão na obra literária de Henry Miller

    Raquel Catunda Pereira

    2016-07-01

    Full Text Available The North American writer Henry Miller was marginalized by literary critics since the first publications of his works in the 40s. Accused of being a pornographic text, the book Tropic of Cancer (1934 was forbidden in many countries. This article aims to analyze the obscene in Henry Miller’s work to prove that, beyond the erotic intention, Miller’s books are an expression of freedom and rejection of moral standards. In order to achieve our goal, we will use as theoretical basis the articles Criticismo e sexualidade: uma leitura de Tropico of Capricorn de Henry Miller, by Flávia Andréa Rodrigues Benfatt, and Literatura marginal americana: do épico confessional ao niilismo erótico, by Lainister de Oliveira. The texts mentioned above grant us the argumentation necessary to the analysis of pornographic discourse in Henry Miller’s literary works as the author’s aesthetics choice of taking himself as a transgressor in a decadent society.

  3. Henry's Constants of Persistent Organic Pollutants by a Group-Contribution Method Based on Scaled-Particle Theory.

    Razdan, Neil K; Koshy, David M; Prausnitz, John M

    2017-11-07

    A group-contribution method based on scaled-particle theory was developed to predict Henry's constants for six families of persistent organic pollutants: polychlorinated benzenes, polychlorinated biphenyls, polychlorinated dibenzodioxins, polychlorinated dibenzofurans, polychlorinated naphthalenes, and polybrominated diphenyl ethers. The group-contribution model uses limited experimental data to obtain group-interaction parameters for an easy-to-use method to predict Henry's constants for systems where reliable experimental data are scarce. By using group-interaction parameters obtained from data reduction, scaled-particle theory gives the partial molar Gibbs energy of dissolution, Δg̅ 2 , allowing calculation of Henry's constant, H 2 , for more than 700 organic pollutants. The average deviation between predicted values of log H 2 and experiment is 4%. Application of an approximate van't Hoff equation gives the temperature dependence of Henry's constants for polychlorinated biphenyls, polychlorinated naphthalenes, and polybrominated diphenyl ethers in the environmentally relevant range 0-40 °C.

  5. The Henry-Saltwater Intrusion Benchmark – Alternatives in Multiphysics Formulations and Solution Strategies

    E Holzbecher

    2016-03-01

    Full Text Available In a classical paper Henry set up a conceptual model for simulating saltwater intrusion into coastal aquifers. Up to now the problem has been taken up by software developers and modellers as a benchmark for codes simulating coupled flow and transport in porous media. The Henry test case has been treated using different numerical methods based on various formulations of differential equations. We compare several of these approaches using multiphysics software. We model the problem using Finite Elements, utilizing the primitive variables and the streamfunction approach, both with and without using the Oberbeck-Boussinesq assumption. We compare directly coupled solvers with segregated solver strategies. Changing finite element orders and mesh refinement, we find that models based on the streamfunction converge 2-4 times faster than runs based on primitive variables. Concerning the solution strategy, we find an advantage of Picard iterations compared to monolithic Newton iterations.

  6. DNA-Catalyzed Henry Reaction in Pure Water and the Striking Influence of Organic Buffer Systems

    Marleen Häring

    2015-03-01

    Full Text Available In this manuscript we report a critical evaluation of the ability of natural DNA to mediate the nitroaldol (Henry reaction at physiological temperature in pure water. Under these conditions, no background reaction took place (i.e., control experiment without DNA. Both heteroaromatic aldehydes (e.g., 2-pyridinecarboxaldehyde and aromatic aldehydes bearing strong or moderate electron-withdrawing groups reacted satisfactorily with nitromethane obeying first order kinetics and affording the corresponding β-nitroalcohols in good yields within 24 h. In contrast, aliphatic aldehydes and aromatic aldehydes having electron-donating groups either did not react or were poorly converted. Moreover, we discovered that a number of metal-free organic buffers efficiently promote the Henry reaction when they were used as reaction media without adding external catalysts. This constitutes an important observation because the influence of organic buffers in chemical processes has been traditionally underestimated.

  7. A French description of German psychology laboratories in 1893 by Victor Henri, a collaborator of Binet.

    Nicolas, Serge; Barnes, Marissa E; Murray, David J

    2015-05-01

    There is a rich tradition of writings about the foundation of psychology laboratories, particularly in the United States but also in France. Various documents exist concerning former German laboratories in American and French literature. But the most interesting French paper was certainly written by a young psychologist named Victor Henri (1872-1940) who was a close collaborator of Alfred Binet (1857-1911) in the 1890s. Visiting various psychology laboratories, he wrote, in 1893, a clear description of the laboratories of Wundt, G. E. Müller, Martius and Ebbinghaus. An English translation is given of Henri's paper and the historical importance of his contribution is here expounded by contrasting the German and French psychologies of the time.

    This research report makes the following claims: 1] There was not an unambiguous economic advantage of hybrid corn over the open-pollinated varieties in 1936. 2] The early adoption of hybrid corn before 1937 can be better explained by a sustained propaganda campaign conducted by the U.S. Department of Agriculture at the direction of the Secretary of Agriculture, Henry Agard Wallace. The Department's campaign echoed that of the commercial seed companies. The most prominent hybrid seed company,...

  19. The delusion of the Master: the last days of Henry James.

    Bartolomeo, Paolo

    2013-11-01

    The novelist Henry James shared with his brother William, the author of the Principles of Psychology, a deep interest in the ways in which personal identity is built through one's history and experiences. At the end of his life, Henry James suffered a vascular stroke in the right hemisphere and developed a striking identity delusion. He dictated in a perfectly clear and coherent manner two letters as if they were written by Napoleon Bonaparte. He also showed signs of reduplicative paramnesia. Negative symptoms resulting from right hemisphere damage may disrupt the feelings of "warmth and intimacy and immediacy" and the "resemblance among the parts of a continuum of feelings (especially bodily feelings)", which are the foundation of personal identity according to William James. On the other hand, a left hemisphere receiving inadequate input from the damaged right hemisphere may produce positive symptoms such as delusional, confabulatory narratives. Other fragments dictated during Henry James's final disease reveal some form of insight, if partial and disintegrated, into his condition. Thus, even when consciousness is impaired by brain damage, something of its deep nature may persist, as attested by the literary characteristics of the last fragments of the Master.

  20. Should bulk cloudwater or fogwater samples obey Henry's law

    Pandis, S.N.; Seinfeld, J.H. (Department of Chemical Engineering and Environmental Quality Laboratory, California Institute of Technology, Pasadena, CA (USA))

    1991-06-20

    In this work we prove that mixing of droplets with different {ital p}H that are individually in Henry's law equilibrium with the surrounding atmosphere always results in a bulk mixture that is supersaturated with weak acids like S(IV) and HCOOH and bases like NH{sub 3} with respect to the original atmosphere. The degree of supersaturation of the bulk liquid water sample for a particular species depends on its dissociation constant, on the initial {ital p}H of the bulk droplet mixture, and on the distribution of the {ital p}H and of the liquid water over the droplet spectrum. High supersaturations result only when the {ital p}H of the bulk droplet mixture exceeds the {ital p}K{sub {ital a}} of the species, in which {ital p}H range large {ital p}H differences among droplets of different sizes lead to large deviations from Henry's law for the bulk mixture. The deviation is shown to depend on the ratio of the arithmetic mean to the harmonic mean of the hydrogen ion concentrations of the droplets with the liquid water content used was weighting factor in the calculation of the means. The theory developed can explain observed discrepancies from Henry's law in atmospheric samples and also other observed phenomena like the reported increase of {ital p}H values of bulk aqueous samples during storage. {copyright} American Geophysical Union 1991

  1. The last ride of Henry II of France: orbital injury and a king's demise.

    Eftekhari, Kian; Choe, Christina H; Vagefi, M Reza; Eckstein, Lauren A

    2015-01-01

    Jousting was a popular pastime for royalty in the Renaissance era. Injuries were common, and the eye was particularly at risk from the splinters of the wooden lance. On June 30, 1559, Henry II of France participated in a jousting tournament to celebrate two royal weddings. In the third match, Gabriel de Montgomery struck Henry on the right shoulder and the lance splintered, sending wooden shards into his face and right orbit. Despite being cared for by the prominent physicians Ambroise Paré and Andreas Vesalius, the king died 10 days later and was found to have a cerebral abscess. The wound was not explored immediately after the injury; nevertheless, wooden foreign bodies were discovered in the orbit at the time of autopsy. The dura had not been violated, suggesting that an infection may have traveled from the orbit into the brain. Nostradamus and Luca Guarico, the astrologer to the Medici family, had prophesied the death of Henry II of France, but he ignored their warnings and thus changed the course of history in Renaissance Europe.

    2015-05-01

    Full Text Available The total, soluble and insoluble oxalate contents of the leaves, stems and buds of Good-King-Henry (Blitum Bonus-Henricus were extracted and measured using HPLC chromatography. The large, mature leaves contained 42% more total oxalate than in the small leaves and the soluble oxalate content of the large leaves was 33% higher than the smaller leaves. Cooking the mixed leaves, stems and buds in boiling water for two minutes significantly (p < 0.05 reduced the total oxalate when compared to the raw plant parts. Pesto sauce made from mixed leaves contained 257 mg total oxalate/100 g fresh weight; this was largely made up of insoluble oxalates (85% of the total oxalate content. Soup made from mixed leaves contained lower levels of total oxalates (44.26 ± 0.49 mg total oxalate/100 g fresh weight and insoluble oxalate made up 49% of the oxalate contents. The levels of oxalates in the Good-King-Henry leaves were high, suggesting that the leaves should be consumed occasionally as a delicacy because of their unique taste rather than as a significant part of the diet. However, the products made from Good-King-Henry leaves indicated that larger amounts could be consumed as the oxalate levels were reduced by dilution and processing.

    Olano, C.; Lemarchand, G.; Sanz, A. J.; Bava, J. A.

    El objetivo principal de este proyecto consiste en el estudio de la distribución y abundancia del CH en nubes interestelares a través de la observación de las líneas hiperfinas del CH en 3,3 GHz. El CH es una molécula de amplia distribución en el espacio interestelar y una de las pocas especies que han sido observadas tanto con técnicas de radio como ópticas. Desde el punto de vista tecnológico se ha desarrollado un cabezal de receptor que permitirá la realización de observaciones polarimétricas en la frecuencia de 3,3 GHz, con una temperatura del sistema de 60 K y un ancho de banda de 140 MHz, y que será instalado en el foco primario de la antena parabólica del IAR. El cabezal del receptor es capaz de detectar señales polarizadas, separando las componentes de polarización circular derecha e izquierda. Para tal fin el cabezal consta de dos ramas receptoras que amplificarán la señal y la trasladarán a una frecuencia más baja (frecuencia intermedia), permitiendo de esa forma un mejor transporte de la señal a la sala de control para su posterior procesamiento. El receptor además de tener características polarimétricas, podrá ser usado en el continuo y en la línea, utilizando las ventajas observacionales y de procesamiento de señal que actualmente posee el IAR.

    Family-based interventions to prevent childhood obesity depend upon parents' taking action to improve diet and other lifestyle behaviours in their families. Programmes that attract and retain high numbers of parents provide an enhanced opportunity to improve public health and are also likely to be more cost-effective than those that do not. We have developed a theory-informed optimisation intervention to promote parent engagement within an existing childhood obesity prevention group programme, HENRY (Health Exercise Nutrition for the Really Young). Here, we describe a proposal to evaluate the effectiveness of this optimisation intervention in regard to the engagement of parents and cost-effectiveness. The Optimising Family Engagement in HENRY (OFTEN) trial is a cluster randomised controlled trial being conducted across 24 local authorities (approximately 144 children's centres) which currently deliver HENRY programmes. The primary outcome will be parental enrolment and attendance at the HENRY programme, assessed using routinely collected process data. Cost-effectiveness will be presented in terms of primary outcomes using acceptability curves and through eliciting the willingness to pay for the optimisation from HENRY commissioners. Secondary outcomes include the longitudinal impact of the optimisation, parent-reported infant intake of fruits and vegetables (as a proxy to compliance) and other parent-reported family habits and lifestyle. This innovative trial will provide evidence on the implementation of a theory-informed optimisation intervention to promote parent engagement in HENRY, a community-based childhood obesity prevention programme. The findings will be generalisable to other interventions delivered to parents in other community-based environments. This research meets the expressed needs of commissioners, children's centres and parents to optimise the potential impact that HENRY has on obesity prevention.

    Ramazan ŞENGÜL

    2007-01-01

    Full Text Available Henri Fayol, developed a managerial approach which is a perfect guide for both private and public sectors through focusing systematically upon managerial process. A major advantage of Fayol in creating a general managerial doctrine was his pratician side. His managerial thought which was developed in the early 20th century lasted up to our times. The distinguished characteristic of Fayol’s thought was studying the administrative reality through separating it into its functions, in that it helps to understand evolution and operation of organisations. The importance of his doctrine for today is that adapting contemporary managerial techniques into organisations of various kinds needs to refer Fayol’s managerial aproach in one way or another.

  9. Staging Henry Fielding: The Author-Narrator in Tom Jones On Screen

    Eli Løfaldli

    2017-06-01

    Full Text Available As recent adaptation theory has shown, classic-novel adaptation typically sets issues connected to authorship and literal and figurative ownership into play. This key feature of such adaptations is also central to the screen versions of Henry Fielding’s Tom Jones (1749. In much of Fielding’s fiction, the narrator, typically understood as an embodiment of Fielding himself, is a particularly prominent presence. The author-narrator in Tom Jones is no exception: not only is his presence strongly felt throughout the novel, but through a variety of means, ‘The History of Tom Jones, A Foundling’ is also distinctly marked as being under his control and ownership. The two adaptations of Fielding’s novel, a 1963 film and a 1997 television series, both retain the figure of the author-narrator, but differ greatly in their handling of this device and its consequent thematic ramifications. Although the 1963 film de-emphasises Henry Fielding’s status as proprietor of the story, the author-narrator as represented in the film’s voiceover commentary is a figure of authority and authorial control. In contrast, the 1997 adaptation emphasises Fielding’s ownership of the narrative and even includes the author-narrator as a character in the series, but this ownership is undermined by the irreverent treatment to which he is consistently subjected. The representations of Henry Fielding in the form of the author-narrator in both adaptations are not only indicative of shifting conceptions of authorship, but also of the important interplay between authorship, ownership and adaptation more generally.

    In the frame of the French Metrology Institute, the Laboratoire National Henri Becquerel performs accurate characterization of semiconductor detectors that are in use in a number of applications. Their efficiency calibration, energy resolution and the detailed shape of their response function are parameters of interest for accurate processing of low-energy X-ray spectra to be applied to elements identification and fundamental research studies. The tools specifically developed for low-energy detectors calibration and characterization are described, from the use of radioactivity standard to the development of a tunable monochromatic X-ray source.

  11. Literary Practice according to Michel Henry: A Philosophical Introduction to his Novels

    Jean-Baptiste Dussert

    2012-12-01

    Full Text Available Although the author of four novels, Michel Henry never produced an aesthetics of literature. The purpose of this article is, after a presentation of his philosophy of immanence and his concept of life, to locate where the literary practice takes place in his system. In this study, we are not interested in the poetic quality of his works, but in the possibility to base his singular creativity on his philosophical reflection. This leads us to insert literature in the vast phenomenon of culture and ethics, and to grasp the function of poetics in the struggle against barbarism.

  12. Ernest Henry Starling (1866-1927): the scientist and the man

    Henriksen, Jens H

    2005-01-01

    The pre-eminent achievements of the English physician and physiologist Ernest Henry Starling were his quantitative explanation of the transcapillary transport of fluid, the discovery of the first hormone, secretin, and his formulation of the law of the heart. In some ways Starling was an outsider...... and he was the centre of several scientific and social controversies. However, throughout his life he stressed fundamental scientific attitudes and ideas with remarkable persistence and power, although also balance, and his scientific achievements have stood the test of time....

  15. Confronting empty spaces: between interpretation and experience in "The Turn of the Screw" by Henry James

    Antonia Spinelli

    2015-01-01

    Full Text Available The Turn of the Screw by Henry James has inspired the most various critical debates for over a century. What is hidden in the folds of the story? What kind of impact does it have on the reader? Like a borderless nebula who attracts and reflects light from other stars, this novella is permeated by a vide fascinant, by a chaotic and disturbing matter “such stuff as dreams are made”. This feeling of absence and uncertainty, that characterizes the story, developed trough the contribution of readers and critics and it found a further still precious echo in The Innocents, a film directed by Jack Clayton in 1961.

    2010-07-01

    The primary assertion is that this article argues that the recovery in production of hydropower in Henry Borden (UHB) is the reduction of environmental liabilities in the Billings reservoir. In this context, the aim of this paper is to provide a first consideration of the possibility of recovery of production Henry Borden hydropower plant of recovering the multiple uses of the reservoir. From this perspective, we interviewed representatives of CETESB (Sanitation Environmental Technology Company) and EMAE (Metropolitan Water and Energy Company SA) for consideration of actions that include environmental policies aimed at increasing the production of electricity in Henry Borden in order to obtain results that may contribute to the multiple uses of the Billings reservoir. Noting that the range of laws aimed at protecting the water sources was limited to disjointed public policy that has reduced the resilience of the Billings reservoir. (author)

  17. Ecrire et souffrir : L’inspiration partagée de Constance Fenimore Woolson et de Henry James Literature and Grief: Constance Fenimore Woolson and Henry James, A Common Inspiration

    Jeannine Hayat

    2007-01-01

    Full Text Available Miss Grief is a story by Constance Fenimore Woolson, an American novelist who often wrote about the difficulty a woman had in becoming an artist — a writer or a painter — in the nineteenth century. This tale is a very strange text, a kind of anticipation of a meeting to come, in Italy, in 1880, between Woolson and Henry James, and a friendship which lasted until the former’s death in 1894. For thirteen years, both writers would share a common inspiration. Death itself could not break the links between the two authors, who were connected even when settled in different European countries. William James, who was a member of the American Society for Psychical Research, probably helped his brother Henry to communicate — or so it appears — in some way with Woolson, even after her fatal accident, or possible suicide, in Venice. Henry James probably had in mind Miss Grief, a story by his dead friend, before writing some of his books. Indeed, Woolson had been the first to develop the image of “the figure in the carpet,” which was later transformed by Henry James. Woolson was also the first to devise a plot which Henry James would later use as a canvas for his novel The Wings of the Dove. What is an author and what is authorship? It seems impossible to separate what is Woolson’s and what is Henry James’s in four works of fiction that are in fact to be read together : Miss Grief, The Figure in the Carpet, The Beast in the Jungle, The Wings of the Dove.

  19. Theoretical Insight of Physical Adsorption for a Single Component Adsorbent + Adsorbate System: II. The Henry Region

    Chakraborty, Anutosh

    2009-07-07

    The Henry coefficients of a single component adsorbent + adsorbate system are calculated from experimentally measured adsorption isotherm data, from which the heat of adsorption at zero coverage is evaluated. The first part of the papers relates to the development of thermodynamic property surfaces for a single-component adsorbent + adsorbate system1 (Chakraborty, A.; Saha, B. B.; Ng, K. C.; Koyama, S.; Srinivasan, K. Langmuir 2009, 25, 2204). A thermodynamic framework is presented to capture the relationship between the specific surface area (Ai) and the energy factor, and the surface structural and the surface energy heterogeneity distribution factors are analyzed. Using the outlined approach, the maximum possible amount of adsorbate uptake has been evaluated and compared with experimental data. It is found that the adsorbents with higher specific surface areas tend to possess lower heat of adsorption (ΔH°) at the Henry regime. In this paper, we have established the definitive relation between Ai and ΔH° for (i) carbonaceous materials, metal organic frameworks (MOFs), carbon nanotubes, zeolites + hydrogen, and (ii) activated carbons + methane systems. The proposed theoretical framework of At and AH0 provides valuable guides for researchers in developing advanced porous adsorbents for methane and hydrogen uptake. © 2009 American Chemical Society.

    A portrait of Henry VIII on oak panel c. 1535 has recently undergone technical examination to inform questions regarding authorship and the painting's relationship to a group of similar works in the collections of the National Portrait Gallery, London, and the Society of Antiquaries. Due to previous conservation treatments of the painting, the conventional transmission X-radiograph image was difficult to interpret. As a result, the painting underwent high-definition X-ray fluorescence (XRF) elemental mapping on the X-ray fluorescence microscopy beamline of the Australian Synchrotron. Scans were conducted at 12.6 and 18.5 keV, below and above the lead (Pb) L edges, respectively. Typical scan parameters were 120 μm pixel size at 7 ms dwell time, with the largest scan covering an area 545 x 287 mm{sup 2} collected in 23 h (10.8 MP). XRF mapping of the panel has guided the conservation treatment of the painting and the revelation of previously obscured features. It has also provided insight into the process of making of the painting. The informative and detailed elemental maps, alongside ultra-high-definition scans of the painting undertaken before and after varnish and over-paint removal, have assisted in comparison of the finely painted details with the London paintings. The resolution offered by the combination of imaging techniques identifies pigment distribution at an extremely fine scale, enabling a new understanding of the artist's paint application. (orig.)

    Full Text Available O engenheiro francês Henri Fayol (1841-1925 é usualmente apresentado aos estudantes de Administração como o Pai da Escola Clássica de Administração, o que demonstra uma representação limitada da amplitude de sua contribuição para a evolução do pensamento administrativo. Além disso, é frequentemente associado ao seu contemporâneo, o teórico norte-americano Frederick Taylor, sendo aos dois atribuída a defesa de um modelo autoritário de administração. Entretanto, recentemente, pesquisadores descobriram, através do exame de documentos raros e inéditos, um desconhecido retrato desse pioneiro. Este trabalho resulta de uma investigação que buscou levantar fontes de informação bibliográfica disponíveis, publicadas ou não, incluindo resultados de trabalhos de pesquisadores da França, dos Estados Unidos, do Canadá, da Austrália e do Japão. Esses pesquisadores compõem um reduzido grupo de estudiosos, aqui denominados “novos fayolistas” porque retomam, depois de anos de quase amnésia no meio acadêmico, o interesse pelas contribuições de Henri Fayol. Tais estudos revelam conceitos desenvolvidos por Fayol que antecipam aspectos de teorias e práticas da Administração que, somente mais tarde, seriam desenvolvidas, como a Escola de Relações Humanas, a Teoria Contingencial e o Planejamento Estratégico. Ao apresentar as recentes pesquisas sobre o homem e o teórico Henri Fayol, este estudo permite, aos docentes e estudantes de língua portuguesa, acesso a escritos e palestras de sua autoria que, até então, permaneciam desconhecidos.

  10. A Note on Child Neglect in American Victorianism: Henry James’ "The Pupil"

    F. Gül KOÇSOY

    2016-12-01

    Full Text Available In this study, the theme of “neglected child” in Henry James’ “The Pupil” (1891 is explored. Morgan is a neglected child with unscrupulous parents who hold strictly on the Victorian values which reflect American cultural consciousness in the last decades of 19th century. Although he is a brilliant boy, the family does not love him; because he reminds them of their vulgarity. They neglect him physically and emotionally, seeing him as a burden. Although his tutor tries to keep the boy from the family’s corruption, he contributes to his death; he neglects his illness and deserts him when he is most needy. As an interpreter, James draws attention to the situation of children that are not working but being tutored at home. He criticizes this culture’s general attitude towards children. It is a disturbing social reality and he shows how that materialistic culture victimizes children in terms of neglectful parenting

    Akhtar, Naheed; Zheng, Yarui; Nazir, Mudassar; Wu, Yulin; Deng, Hui; Zheng, Dongning; Zhu, Xiaobo

    2016-12-01

    In the preparations of superconducting qubits, circuit design is a vital process because the parameters and layout of the circuit not only determine the way we address the qubits, but also strongly affect the qubit coherence properties. One of the most important circuit parameters, which needs to be carefully designed, is the mutual inductance among different parts of a superconducting circuit. In this paper we demonstrate how to design a gap-tunable flux qubit by layout design and inductance extraction using a fast field solver FastHenry. The energy spectrum of the gap-tunable flux qubit shows that the measured parameters are close to the design values.

    Full Text Available The right to the city, defined by Henri Lefebvre in 1967 as the right of urban inhabitants to build, decide and create the city, and make of it a privileged space of anti-capitalist struggle, is again at the center of political debate. Social scientists, social movements, international aid agencies and States take it as a benchmark for policy analysis and to discuss the urban changes in contemporary capitalist cities. This article discusses the assumptions made by Lefebvre in 1967 and the transformation that the concept of right to the city has had from authors such as David Harvey, Edward Soja and Ana Fani Alessandri Carlos.

  14. About Time. Physics, Philosophy and the Battle Between Albert Einstein and Henri Bergson

    Frank, Adam

    The historical relationship between physics and philosophy has had many famous high and low points. The two function best when both can challenge and support each other. In this talk I explore the famous debate between Albert Einstein and Henri Bergson over the nature of time. While history rightly judged Einstein to have won the debate in terms of relativity, there were deeper aspects of Bergsons critique that remain unappreciated. We will explore the different ways philosophy approaches the issue of time. In particular, we will look at the Continental Schools\\x9D, such as Phenomenology, which brings a unique perspective to the debate lying outside the traditional approach of physicists. From this perspective questions related to the act of being an observer, its essential subjective nature and the proper context of physics can be explored.

    Full Text Available The book Rethinking Social Inquiry, edited by Henry E. BRADY and David COLLIER, is a response to a book by KING, KEOHANE and VERBA (1994 that aimed to introduce quantitative standards to qualitative research. The authors of the book reviewed here criticize many of the suggestions made there because they argue that qualitative research requires other tools. Nevertheless, they agree that the foundations of research design are similar. The book comprises a comprehensive critique of mainstream quantitative techniques, describes a set of qualitative tools for research, and addresses issues of how to combine qualitative and quantitative approaches to maximize analytical leverage. It is an excellent contribution to the methodological debate in the social sciences. URN: urn:nbn:de:0114-fqs0602309

  16. Henry Moore’s Public Sculpture in the US: The Collaborations with I. M. Pei

    Alex Potts

    2016-07-01

    Full Text Available The many commissions Henry Moore received for public sculpture in the United States provided the occasion for several quite distinctive works. While not site specific, these were unique, and their final form, scale, and disposition was elaborated with a particular setting in mind. This aspect of Moore’s work in the US, which began with the monumental piece he designed for the Lincoln Center in New York in 1963–65, is examined here by focusing on the productive relationship he forged with the architect I. M. Pei in the 1970s. The sculptures Moore produced in collaboration with Pei respond in suggestive ways to the spatial environments created in American cities by late modern architectural developments. They also realize an oddly effective combination of the biomorphic and abstract that differs both from the bodily conception of Moore’s earlier work and the non-figurative character of much public sculpture of the time.

  3. Anarchism and homosexuality in Wilhelmine Germany: Senna Hoy, Erich Mühsam, John Henry Mackay.

    Fähnders, W

    1995-01-01

    Homosexuality and its social and legal suppression were heatedly discussed in early twentieth-century Germany, including on the left. Among the anarchists, positions with markedly diverse forms of argument were espoused by such prominent advocates of individualist anarchism as John Henry Mackay and by others coming from the Bakuninist tradition, such as Senna Hoy and Erich Mühsam. Their writings evidence that prior to World War I and into the 1920s, German anarchists--especially when compared with the Social Democrats--intervened consistently on behalf of individual self-determination extending into the sexual sphere, even though an undercurrent of hostility toward homosexuals persisted within the leftist movement as a whole.

Cheek was the author of several papers dealing with the transmutation of species influenced by the theories of Etienne Geoffroy Saint-Hilaire (1772-1844), Jean-Baptiste Lamarck (1744-1829) and the Comte de Buffon (1707-88). Some of these were read to student societies, others appeared in the Edinburgh Journal of Natural and Geographical Science, which Cheek edited between 1829 and 1831. His writings give us a valuable window onto some of the transformist theories that were circulating among Darwin's fellow medical students in the late 1820s, to which Darwin would have been exposed during his time in Edinburgh, and for which little other concrete evidence survives.

  6. How the Other Half Lives: Under the Arch with Lady Henry Somerset

    2017-10-01

    Full Text Available The reforming work of Isabella Caroline Somerset (Lady Henry Somerset 1851-1921 is largely overlooked today. Dedicated to women’s causes at home and abroad and to temperance in particular, having first-hand knowledge of the privileged and the underprivileged, this determined, multi-talented and opinionated woman uncharacteristically wrote a fictional novel, Under the Arch (1906. In the novel, London aristocrats are portrayed rubbing shoulders with slum dwellers, but there is little real connection. The problems that the social policies introduced by the Liberals from 1906-1914 would address are nevertheless highlighted. It can be no coincidence that Somerset was well acquainted with many of these politicians. The themes of relieving the poor, Christian doctrine, marriage, women’s suffrage and imperialism are addressed, although Somerset’s focus is simply on “doing good” and loving one’s neighbour

  7. Henry Solomon Wellcome: A philanthropist and a pioneer sponsor of medical research in the Sudan.

    Adeel, Ahmed Awad A

    2013-01-01

    Henry Solomon Wellcome, the famous drug manufacturer had a fascinating association with the Sudan. Besides supporting tropical medicine research in this country, he established an extensive project in the Sudan that aimed at combining archeological excavations, philanthropy and social reform. This article is an archives-based account on this side of Wellcome's association with the Sudan. The article starts with Wellcome's early years in the American Midwest and the evolution of his career and his rise as a world-renowned drug manufacturer. After the battle of Omdurman, Wellcome visited Sudan in 1900 - 1901 where he offered to support the establishment of the research laboratories which later came to be known as the Wellcome Tropical Research Laboratories in Khartoum. He then became directly involved in the planning and running of extensive archeological excavations in the central Sudan. This project served as a field in which Wellcome found an outlet for his philanthropy. More than 4000 labourers were employed in Jebel Moya. Professional archeologists and anatomists were recruited by Wellcome to supervise the work, and all the requirements in terms of equipment were catered for. Wellcome devised a Savings Bank System whereby part of the earnings of each labourer were saved to him till the end of the season. He also introduced one of his innovations: aerial photography using box kite which was used for the first time in archeology. Wellcome made it a rule that no applicant should be turned away. The Camp Commandant had to find suitable work for each applicant, including the handicapped who were assigned to appropriate jobs like mending baskets or cutting grass for building huts. Wellcome's welfare work had a significant impact on the local inhabitants of Jebel Moya. Henry Solomon Wellcome, 1906. Oil painting by Hugh Goldwin Riviere. Credit: Wellcome Library.

  8. Style and non-style in anatomical illustration: From Renaissance Humanism to Henry Gray.

    Kemp, Martin

    2010-02-01

    Style is a familiar category for the analysis of art. It is less so in the history of anatomical illustration. The great Renaissance and Baroque picture books of anatomy illustrated with stylish woodcuts and engravings, such as those by Charles Estienne, Andreas Vesalius and Govard Bidloo, showed figures in dramatic action in keeping with philosophical and theological ideas about human nature. Parallels can be found in paintings of the period, such as those by Titian, Michelangelo and Hans Baldung Grien. The anatomists also claimed to portray the body in an objective manner, and showed themselves as heroes of the discovery of human knowledge. Rembrandt's painting of Dr Nicholas Tulp is the best-known image of the anatomist as hero. The British empirical tradition in the 18th century saw William Cheselden and William Hunter working with techniques of representation that were intended to guarantee detailed realism. The ambition to portray forms life-size led to massive volumes, such as those by Antonio Mascagni. John Bell, the Scottish anatomist, criticized the size and pretensions of the earlier books and argued for a plain style adapted to the needs of teaching and surgery. Henry Gray's famous Anatomy of 1858, illustrated by Henry Vandyke Carter, aspired to a simple descriptive mode of functional representation that avoided stylishness, resulting in a style of its own. Successive editions of Gray progressively saw the replacement of Gray's method and of all his illustrations. The 150th anniversary edition, edited by Susan Standring, radically re-thinks the role of Gray's book within the teaching of medicine.

It is the digital library in all its aspects, it is the repository library for cultural heritage and “passive” collections and it offers a working place in its wonderful book tower of Henry van de Velde. The story of the book tower starts in the 1930s when Henry van de Velde was asked to build a University Library and offices for the department of Art history. His tower-idea was not exactly what the chief librarian had in mind, so he had to (network hard to get the building he wanted. It was finished on the verge of the second world war. The concrete building has a height of 64 meter, has 24 floors and a “belvedere” and houses almost 3 million books in closed racks. The university did not neglect the tower during all these years, but was not always aware of the historical value and often choose the cheapest way for building matters. A couple of years ago a private person bought the Van de Velde archive of the book tower (which was in private hands, got fascinated with the building, got angry because of lack of care and networked (maybe as hard as Van de Velde once did to get it built to get it restored.

    Abel Niepce was rarely mentioned during the celebration of the centenary of the radioactivity discovery.This discovery, supposed due to chance alone, is entirely attributed to Henri Becquerel. But Abel Niepce who made the first observation of radiation from uranium with the impression of a photographic plate, but without giving it meaning. This is a slow process which in forty years, from an observation misunderstood by Abel Niepce to its interpretation by Frederick Soddy, through the experiments of Henri Becquerel and thanks to developments in other knowledge (electron, X-rays) has led to a scientific progress known under the term of radioactivity, name given by Marie Slodowska-Curie.

  14. Une autre ville pour une autre vie. Henri Lefebvre et les situationnistes

    Philippe Simay

    2008-12-01

    Full Text Available L’un des traits distinctifs du mouvement situationniste est de s’être constamment préoccupé de la question urbaine. Conçue comme l’espace de production de la société du spectacle mais aussi comme un terrain de lutte et d’expérimentation, la ville a représenté pour ce mouvement estudiantin, proche d’Henri Lefebvre, le lieu d’une réinvention radicale de la vie quotidienne. Cet article revient sur la critique situationniste de l’urbanisme de l’après-guerre ainsi que sur les pratiques auxquelles elle a donné lieu (détournement, dérive, cartes psychogéographiques, construction de situations éphémères. Celles-ci peuvent être regardées comme la première expression d’un « droit à la ville », tel que l’entendait Lefebvre. Reste à savoir si le groupe de Guy Debord souhaitait véritablement « changer la ville pour changer la vie » ou si la ville n’était que le théâtre d’une révolution à venir.One of the distinctive traits of the situationist movement is its constant preoccupation with the urban issue. For this student movement close to Henri Lefebvre, the city has been thought of as a choice generic location for the production of the Society of the Spectacle, but also as a test ground for struggle and experimentation – the place where a radical reinvention of daily life can occur. This paper goes back to the situationist critique of post-war urbanism, as well as the behaviors and practices it has given birth to (misappropriation, drifts in meaning, psychogeographic maps, the construct of short-lived situations. These can be seen as the first expression of a « right to the city », in the sense Lefebvre originally meant it have. However, it is still unknown whether Guy Debord's group really wished to « change city-life to change life itself », or if to them the city was merely a theater for the enactment of a revolution to come.

  20. A unified description of adsorption on real surfaces from the Henry Range to the formation of the liquid layer

    Cerofolini, G F

    1977-01-01

    A unified description of adsorption on real surfaces from the Henry Range to the formation of the liquid layer was developed on the basis of the BET theory and the assumption that sites on real surfaces are not energetically homogeneous. The model describes the successive Henry, Dubinin-Radushkevich, Freundlich, and multilayer BET behavior of the adsorbed phase as the pressure increases. An analysis of isotherms over the whole coverage range showed that the heterogeneous surface character decreases with increasing number of adsorbed layers; that adsorption into the first and higher layers may be competitive, which produces a new isotherm resembling a mixed type II and III isotherm as proposed by Cerofolini and coworkers.

  4. A pioneer of Australian paediatrics: Dr Henry Edward Brown (1858-1931).

    Isles, Alan F; Roper, Peter; Pearn, John H

    2014-11-13

    The emergence of paediatrics as a specialty in Australian medicine dates from the last two decades of the 19th century. Among the pioneers of pre-Federation paediatrics, we include Dr Henry Edward Brown (1858-1931), an Irish-born physician and surgeon who became the first paediatrician to practise in the northern half of the Australian continent. In 1885, he was appointed as the medical superintendent of the Rockhampton Children's Hospital, itself a pioneer institution in the care of sick and injured children. Dr H.E. Brown also served as medical officer of health concurrently in three Queensland shires. He was a leader in the literary and sporting life of the busy port town of Rockhampton and a scholar and significant philanthropist in the domain of French literature. His life was and remains an exemplar of a class of pre-Federation paediatricians who established the ethos of clinical and societal service, which remains as a core feature of the speciality discipline of paediatrics in the 21st century. © 2014 The Authors.

  5. El urbanismo contra lo urbano. La ciudad y la vida urbana en Henri Lefebvre

    Manuel Delgado Ruiz

    2018-01-01

    Full Text Available Henri Lefebvre coloca en el eje de su teoría sobre la vida urbana la oposición entre el espacio vivido por quienes lo usan o sueñan y el espacio abstracto que creen organizar los tecnócratas de la ciudad, que raramente reconocen hasta qué punto su “creatividad” está sometida a intereses privados o institucionales. Tras ese espacio hipotético sobre el que urbanistas y arquitectos trabajan no hay otra cosa que mera ideología, es decir, fantasma que recubre y disfraza las relaciones sociales reales de producción. Frente -o de espaldas- a ese orden espacial meramente teórico de los “especialistas”, lo que las ciudades conocen es la actividad constante o inminente de lo urbano, entendido como apoteosis y exacerbación de lo social, dinamismo siempre activado de acontecimientos y quehaceres sobre el que los “expertos” aplican planes y proyectos, pero del que no saben en realidad nada, acaso por lo cual pugnan por anularlo.

  6. Derivation of the MMPI-2-RF Henry-Heilbronner Index-r (HHI-r) scale.

    Henry, George K; Heilbronner, Robert L; Algina, James; Kaya, Yasemin

    2013-01-01

    The 15-item Henry-Heilbronner Index (HHI) was published in 2006 as an MMPI-2 embedded measure of psychological response validity. When the MMPI-2 was revised in 2008 only 11 of the 15 original HHI items were retained on the MMPI-2-RF, prohibiting use of the HHI as an embedded validity indicator on the MMPI-2-RF. Using the original HHI sample an 11-item version of the HHI, the HHI-r, was evaluated for use as an embedded measure of psychological response validity for the MMPI-2-RF. The 11-item HHI-r was very similar to the HHI in classification accuracy. An HHI-r cutoff score of ≥7 was associated with a classification accuracy rate of 84.0%, good sensitivity (68.9%), and high specificity (93.2%) in identifying symptom exaggeration in personal injury and disability litigants versus non-litigating head-injured patients. These preliminary results suggest the HHI-r functions in a manner similar to the original HHI as a measure of psychological response validity, and may be used by psychologists and neuropsychologists as an MMPI-2-RF embedded validity indicator.

  7. Henry's Law vaporization studies and thermodynamics of einsteinium-253 metal dissolved in ytterbium

    Kleinschmidt, P.D.; Ward, J.W.; Matlack, G.M.; Haire, R.G.

    1984-01-01

    The cohesive energy of metallic einsteinium determines whether einsteinium is a trivalent or divalent metal. The enthalpy of sublimation, a measure of the cohesive energy, is calculated from the partial pressures of einsteinium over an alloy. The partial pressure of 253 Es has been measured over the range 470--870 K, using combined target and mass spectrometric Knudsen effusion techniques. An alloy was prepared with einsteinium dissolved in a ytterbium solvent to produce a very dilute solution. Partial pressure measurements on the alloy were amenable to the experimental technique and a data analysis using a Henry's law treatment of the data. Vapor pressure data are combined with an estimated crystal entropy S 0 298 and ΔC 0 /sub p/ for ytterbium, to produce enthalpy, entropy, and free energy functions from 298 to 1300 K. The vapor pressure of einsteinium in a dilute einsteinium--ytterbium alloy is described by the equation log P(atm) = -(6815 +- 216)/T+2.576 +- 0.337, from which we calculate for the enthalpy of sublimation of pure einsteinium ΔH 0 298 (second law) = 31.76 kcal/mol. The value of the enthalpy of sublimation is consistent with the conclusion that Es is a divalent metal

  8. Oestrogen and progesterone receptor assays in breast tumours. The Prince Henry's Hospital experience, 1983-1990.

    1993-08-16

    To present and analyse the results of eight years of experience (1983-1990) in breast tumour receptor analysis. All female primary breast tumour samples received (4683) were analysed for seasonal variation, patient age, relative risk index, oestrogen receptor (ER) and progesterone receptor (PR) status, ER and PR status as a function of age, ER and PR levels as a function of age, and ER and PR levels as a function of month of analysis. The assays were done at the Medical Research Centre, Prince Henry's Hospital, Melbourne, as a non-profit service to surgeons, oncologists and pathologists. The numbers of samples referred for assay increased progressively each year, from 473 in 1983 to 1097 in 1990, but the receptor status (ER +/-, PR +/-) appeared not to vary from year to year. ER+PR+ tumours were the most common in all age groups, steadily increasing from between 50% and 60% in premenopausal women to 70% or more in those aged over 80. In postmenopausal women, levels of ER in ER+ tumours were three times those in premenopausal women; PR levels in PR+ tumours, however, were bimodal, with higher levels in the age groups 35-49 and 70-89 years than in women aged 50-69 years. No significant seasonal variation was seen, and the overall patterns of receptor status are similar to those seen in Northern hemisphere studies.

  9. [Henri-Léonard Bertin and the development of agriculture in the Age of Enlightenment].

    Pédro, Georges

    2012-05-01

    This meeting of the Committee on the History of Science and Epistemology takes place as we celebrate the 250th anniversary of the creation of the world's first veterinary schools, a major event among all those that, in the wake of the Physiocrat movement initiated by Quesnay and DuPont de Nemours, shaped the modernisation of agriculture in France during the 18th century. Henri-Léonard Bertin (1720-1792) was the impetus to the restructuring process. He was well aware that farming should not remain an activity that solely provides a livelihood for the population, but that it needed to be modernised, i.e. it should produce more, and better. His view was that agriculture could become a great source of riches for France and therefore, a true economic and even political force. He used the various official positions he occupied during that period (Intendant of Lyon (1754-1757), Controller General of Finances (1759-1763), Minister-Secretary of State for Agriculture (1763-1780) to initiate a number of reforms that brought about the modernisation of the kingdom's agricultural world.

  10. Reformation or Revolution? Herman Bavinck and Henri de Lubac on Nature and Grace

    2017-10-01

    Full Text Available Henri de Lubac’s treatment of the relationship between nature and grace will be critiqued by Herman Bavinck’s ‘grace restores nature’ theme. In two significant addresses, Bavinck critiqued a Roman Catholic approach to nature and grace. De Lubac’s influence upon Roman Catholic thinking addressing nature and grace occurred post-Bavinck and has altered Catholic thinking on the subject. Neo-Calvinist scholar, Wolter Huttinga admits that Bavinck and de Lubac offer similar critiques of Roman Catholicism (Huttinga 2014. The question remains then, do Bavinck’s critiques still hold? I propose that Bavinck’s account of grace restores nature still makes valid critiques of a post-Vatican II construction of nature and grace. The paper is broken into three sections: (1 an exploration of de Lubac’s nature and grace theme, (2 the framework of Bavinck’s ‘grace restores nature’ theme, and (3 a Bavinckian critique of de Lubac’s nature and grace theme.

  12. Henry Hollingsworth Smith and His Bibliographical Index and Historical Record: The Beginning of American Surgical Historiography.

    Rutkow, Ira

    2016-04-01

    To explore the details of Henry Hollingsworth Smith's (1815-1890) achievement as the first physician to organize in a systematic and chronologic manner the details of the history of surgery in America and prepare a register of men who performed surgical operations. The life of Smith, the earliest of the nation's surgeons to elucidate the history of American surgery, is little known. His boosting the image of the scalpel wielder helped shape the future of the craft, in particular, surgery's rise as a specialty and profession. An analysis of the published medical literature and unpublished documents relating to Smith and his work to document the history of American surgery. During the 1850 s, a time when surgery was not considered a separate branch of medicine but a mere technical mode of treatment, Smith's efforts in surgical history provided much needed encouragement to surgeons in their pursuit of professional recognition. Although Smith's accomplishment as the nation's first compiler of the history of American surgery has long been forgotten, his effort afforded the men who performed surgical operations their earliest measure of self-respect. As such, Smith belongs in America's pantheon of surgical heroes.

  13. Two-relaxation-time lattice Boltzmann method for the anisotropic dispersive Henry problem

    Servan-Camas, Borja; Tsai, Frank T.-C.

    2010-02-01

    This study develops a lattice Boltzmann method (LBM) with a two-relaxation-time collision operator (TRT) to cope with anisotropic heterogeneous hydraulic conductivity and anisotropic velocity-dependent hydrodynamic dispersion in the saltwater intrusion problem. The directional-speed-of-sound technique is further developed to address anisotropic hydraulic conductivity and dispersion tensors. Forcing terms are introduced in the LBM to correct numerical errors that arise during the recovery procedure and to describe the sink/source terms in the flow and transport equations. In order to facilitate the LBM implementation, the forcing terms are combined with the equilibrium distribution functions (EDFs) to create pseudo-EDFs. This study performs linear stability analysis and derives LBM stability domains to solve the anisotropic advection-dispersion equation. The stability domains are used to select the time step at which the lattice Boltzmann method provides stable solutions to the numerical examples. The LBM was implemented for the anisotropic dispersive Henry problem with high ratios of longitudinal to transverse dispersivities, and the results compared well to the solutions in the work of Abarca et al. (2007).

  14. Henry Fayol’s 14 Principles of Management: Implications for Libraries and Information Centres

    Uzuegbu, C. P.

    2015-06-01

    Full Text Available This paper focuses generally on the ‘fourteen principles of management’ by Henri Fayol. However, it specifically analyses their application to and implications for libraries and information centres. An extensive review of published works on management generally, and library management in particular, was conducted. This yielded vital insights on the original meaning and later modifications of these principles, as well as their application in the management of various organisations. Consequently, the strengths and weaknesses of these principles were examined to determine their suitability in libraries and information centres. Inferences, illustrations, and examples were drawn from both developed and developing countries which gives the paper a global perspective. Based on available literature, it was concluded that Fayol’s principles of management are as relevant to libraries as they are in other organisations. The paper, therefore, recommends that in addition to modifying some aspects to make these principles more responsive to the peculiar needs of libraries, further research should be undertaken to expand the breadth of these principles and ascertain their impacts on the management of information organisations.

Surface area of the as-synthesized, calcined, and rehydrated catalysts was determined by N2 physisorption at −196 °C. CO2 temperature-programmed desorption (CO2-TPD was applied to determine the basic sites of catalysts. The catalytic test reaction was carried out using benzaldehyde and their derivatives with nitromethane and their derivatives. The Henry products (1–15 were obtained in a very good yield using MgAl-HT-RH catalyst either by conventional method at 90 °C in liquid phase or under microwave irradiation method. The mesoporous structure and basic nature of the rehydrated solid catalyst were responsible for its superior catalytic efficiency. The robust nature was determined by using the same catalyst five times, where the product % yield was almost unchanged significantly.

  16. Henry's law and accumulation of weak source for crust-derived helium: A case study of Weihe Basin, China

    2017-12-01

    Full Text Available Crust-derived helium is generated from the radioactive decay of uranium, thorium and other radioactive elements in geological bodies. Compared with conventional natural gas, helium is a typical weak source gas as a result of extremely slow generation rate and absence of helium-generating peak. It is associated with methane or carbon dioxide reservoirs frequently and related to groundwater closely. Helium can meet the industry standard with 0.1% in volume fraction. In order to study the accumulation mechanism of helium, the previous research on Henry's coefficient and solubility of helium, nitrogen and methane are summarized and the key roles of Henry's Law in the helium migration, accumulation and preservation are discussed by simulating calculation taking Weihe Basin as an example. According to the Law, the gas solubility in dilute solution is controlled by the gas partial pressure and the Henry's coefficient. Compared with the carrier gases, the Henry's constant of helium is high, with striking difference at low and high temperature. In addition, the helium partial pressure is greatly different in helium source rocks and gas reservoirs, resulting in the great differences of helium solubility in the two places. The accumulation progresses are as follows. Firstly, helium can dissolve into water and migrate out of helium source rocks due to the high helium solubility, which is caused by high helium partial pressure and high temperature in source rock. Secondly, when dissolved helium is transported to the shallow gas reservoir, it is prone to be out of solution and into reservoir due to the extremely low partial pressure and low temperature. Meanwhile part of carrier gases dissolves into water, as if helium is “replaced” out. Furthermore, the low concentration funnel of dissolved helium is formed near the gas reservoir, then other dissolved helium continues to migrate towards the gas reservoir, which greatly improves the helium accumulation

    2012-06-01

    Full Text Available La literatura en dirección de empresas durante los últimos 20 años ha analizado diferentes aspectos de la perdurabilidad empresarial, sobre todo lo relacionado con el papel del líder, la asociación con la rentabilidad, y los efectos que genera en el tejido empresarial. Sin embargo, aún existen muchos aspectos en los cuales se debe profundizar. El primero de ellos es dar solución a la diversidad terminológica existente. Al no tener un consenso sobre el concepto, se utilizan de manera indiscriminada términos como longevidad, sostenibilidad, éxito, supervivencia, duración, etc., los cuales en lugar de aclarar, generan confusión. Por otro lado, tampoco hay evidencia suficiente para sugerir alternativas que permitan a las empresas lograr ser perdurables. El artículo que se presenta se fundamenta en una revisión exhaustiva del concepto de perdurabilidad empresarial, y hace una relación de los principales hallazgos encontrados en la literatura sobre las condiciones que pueden facilitar la perdurabilidad empresarial. Con ello se pretende de avanzar en el estudio de la relación entre la perdurabilidad, el comportamiento estratégico de las empresas y desempeño financiero.

  18. [The materialistic strategy of Henry Howard, a Québec alienist (1815-1887).].

    Fugère, A

    1978-01-01

    At the end of the 19th century, Henry Howard appeared as the first Quebec "aliéniste" to attempt to develop an inclusive theoretical treatise on the question of madness. Why this sudden upheaval ? There existed numerous european theories ; that might have sufficed. The author attempts to show the multiple connections of this theoretical pro-lect to the socio-political problems of québécois society. Howard tries, from the perspective of the theory which he elaborates, to intervene in the major discussions affecting Quebec: ultra montanism, the problem of universal compusory education, public morality. At a more professional level he attempts to intervene in the legal dispute opposing judicial and medical competence in the cases of insanity pleas, as well as in the question of the scientific and social status of the "aliéniste". The involvement in these struggles manifests itself in Howard's treatise as much at the level of the concepts themselves, and their architecture, as at the thematic level and in the applications which he naturally draws. It is not onty external and contingent but works on the text from the inside as well. The article attempts to suggest that at the very moment that the treatise on the alienated-which would become the "science" that we know today- seeks to structure itself into a theory, it cannot break its attachment to its determining social context and that, ignoring its ideological role it, in truth, succeeds only in creating illusion and the impression of a progressive process, all the while being circumstantial and having a verted interest.

  19. The Soundscapes of Henry Mayhew Urban Ethnography and Technologies of Transcription

    2012-11-01

    Full Text Available Contemporary reviewers of London Labour and the London Poor were quick to label as inauthentic both the engraved re-mediations of John Beard’s daguerreotype portraits and Henry Mayhew’s transcription of the voices of London’s street habitués. Mayhew’s literal mediations of patter, slang and speech rhythms were the subject of particular scrutiny.  As one critic acerbically observed: ‘The photographs no doubt are accurate enough, but those dialogues smell of the footlights.’  Such criticisms strike at the core of Mayhew’s commitment to the technologies of faithful mimesis and the mediation of an authentic experience of the everyday lives of London’s wandering tribes.  Sound bites of characteristic speech serve as titles for many of the engraved reproductions of John Beard’s daguerreotypes reinforcing the analogy between visual and textual modes of transcription.  Likewise Mayhew insists that his various re-enactments of the multi-sensorial experience of elbowing through London’s crowded marketplaces and streets are ‘unvarnished’ transparent mediations of its various sounds and voices.  Central to Mayhew’s enterprise is the commitment to recording and capturing a dying way of life.  Now silenced voices are captured and remediated to ‘shock’ and teach through the ‘heart’ to use Mayhew’s terminology.  This paper will reconsider Mayhew’s investment in the power of sympathetic communication in the context of broader transformations in mid-nineteenth century conceptions of the media as a conduit for information rather than as a mechanism of persuasion.

  20. Reinvestigation of the Henry's law constant for hydrogen peroxide with temperature and acidity variation.

    Huang, Daoming; Chen, Zhongming

    2010-01-01

    Hydrogen peroxide is not only an important oxidant in itself; it also serves as both sink and temporary reservoir for other important oxidants including HOx (OH and HO2) radicals and O3 in the atmosphere. Its partitioning between gas and aqueous phases in the atmosphere, usually described by its Henry's law constant (K(H)), significantly influences its role in atmospheric processes. Large discrepancies between the K(H) values reported in previous work, however, have created uncertainty for atmospheric modelers. Based on our newly developed online instrumentation, we have re-determined the temperature and acidity dependence of K(H) for hydrogen peroxide at an air pressure of (0.960 +/- 0.013) atm (1 atm = 1.01325 x 10(5) Pa). The results indicated that the temperature dependence of K(H) for hydrogen peroxide fits to the Van't Hoff equation form, expressed as lnK(H) = a/T - b, and a = -deltaH/R, where K(H) is in M/atm (M is mol/L), T is in degrees Kelvin, R is the ideal gas constant, and deltaH is the standard heat of solution. For acidity dependence, results demonstrated that the K(H) value of hydrogen peroxide appeared to have no obvious dependence on decreasing pH level (from pH 7 to pH 1). Combining the dependence of both temperature and acidity, the obtained a and b were 7024 +/- 138 and 11.97 +/- 0.48, respectively, deltaH was (58.40 +/- 1.15) kJ/(K x mol), and the uncertainties represent sigma. Our determined K(H) values for hydrogen peroxide will therefore be of great use in atmospheric models.

  1. On the article by Henri Poincare' open-quotes on the dynamics of the electronclose quotes

    Logunov, A.A.

    1996-01-01

    The first complete translations into English are presented of two articles written by the outstanding French scientist Henri Poincare and submitted by him in 1905 under the common title of open-quotes Sur la dynamique de l'electronclose quotes to different journals. In the present edition of these articles by H. Poincare, modern notation is used, and the articles are accompanied by comments written by A.A. Logunov. The author of the comments explains the profound physical meaning and essential novelty of the particular points and relationships established by Poincare. Such explanations are often interspersed with quotations from earlier articles by Poincare, thus clearly indicating that the main initial points of the new theory were put forward by the French scientist much before 1905, while certain concepts like 'local' time and the arbitrariness of simultaneity were given a clear explanation from the point of view of physical meaning. A.A. Logunov's book, presenting the works of Poincare on the development of relativity theory, has had quite a high success among specialists interested in the history of physics, and since 1984 it has been published in Russian three times. The present English-language edition is identical to the last 1988 Russian edition, and is dedicated to the 90th anniversary of Poincare's articles 'On the Dynamics of the Electron'. In preparing the English text, fragments were used of the translation of the long article by H.Poincare published in the book by Professor C.W. Kilmister from King's College in London/Special Theory of Relativity, Pergamon Press, New York, 1970/

    To assess the influence of exercise capacity and body mass index (BMI) on 10-year mortality in patients with heart failure (HF) and to synthesize these results with those of previous studies. This large biracial sample included 774 men and women (mean age, 60±13 years; 372 [48%] black) with a baseline diagnosis of HF from the Henry Ford Exercise Testing (FIT) Project. All patients completed a symptom-limited maximal treadmill stress test from January 1, 1991, through May 31, 2009. Patients were grouped by World Health Organization BMI categories for Kaplan-Meier survival analyses and stratified by exercise capacity (<4 and ≥4 metabolic equivalents [METs] of task). Associations of BMI and exercise capacity with all-cause mortality were assessed using multivariable-adjusted Cox proportional hazards models. During a mean follow-up of 10.1±4.6 years, 380 patients (49%) died. Kaplan-Meier survival plots revealed a significant positive association between BMI category and survival for exercise capacity less than 4 METs (log-rank, P=.05), but not greater than or equal to 4 METs (P=.76). In the multivariable-adjusted models, exercise capacity (per 1 MET) was inversely associated, but BMI was not associated, with all-cause mortality (hazard ratio, 0.89; 95% CI, 0.85-0.94; P<.001 and hazard ratio, 0.99; 95% CI, 0.97-1.01; P=.16, respectively). Maximal exercise capacity modified the relationship between BMI and long-term survival in patients with HF, upholding the presence of an exercise capacity-obesity paradox dichotomy as observed over the short-term in previous studies.

  3. Le corps dans l’espace architectural. Le Corbusier, Claude Parent et Henri Gaudin

    Julie Cattant

    2016-12-01

    Full Text Available Le premier geste de l’espace architectural est d’accueillir nos corps humains. En leur offrant un espacement à habiter, il leur permet de s’abriter, de se mouvoir et de se rencontrer. L’homme et l’architecture s’affectent l’un l’autre. Nombreux sont les architectes qui interrogent cette coexistence car, renouveler la pensée de l’espace nécessite de reconsidérer le corps humain. L’étude des relations entre le corps et l’espace chez trois architectes français sera l’occasion d’évoquer les écarts et les convergences entre l’homme et l’architecture. L’œuvre de Le Corbusier, protagoniste du mouvement moderne, maintient ainsi une distance entre un corps machinisé et un espace idéal. Marquée par un mode de pensée dualiste, l’architecture de Le Corbusier annonce toutefois son propre dépassement, dépassement que Claude Parent et Henri Gaudin opèreront par la suite à leur manière, le premier en introduisant l’oblique et la déstabilisation du corps, le second en transgressant la limite de l’espace et du corps pour envisager leur porosité réciproque. Finalement, c’est la manière dont l’homme appréhende l’espace avec son corps qui est questionnée par ces trois architectes, de la prégnance du visuel à son évincement.

    Full Text Available La preocupación por la «cantidad» ha privado durante mucho tiempo en el ámbito educativo; ha sido considerado esencial por los gobiernos la consecución de una «educación para todos». Sin embargo, el aumento de los costos no ha conllevado una mejora sustancial, una disminución efectiva de la ineficacia de los sistemas tradicionales de enseñanza; de ello dan fe las tasas de abandonos y repeticiones de curso. Esto conduce a considerar que la falta de correspondencia entre el aumento de los recursos destinados a educación y el rendimiento de las instituciones educativas sea un problema de «calidad» más que de «cantidad». De ahí que se hable hoy insistentemente de la mejora de la calidad de la educación. Al tema de la «calidad de la educación» se dedicó en 1981 un seminario organizado por la Escuela Asturiana de estudios Hispánicos. En él, Víctor García Hoz definía la calidad educativa «como el modo de ser de la educación que reúne las características de integridad, coherencia y eficacia»1, entendiendo la eficacia como la denotación de que el fin perseguido ha sido alcanzado, más que como producción de algo material, con lo que es posible hablar en términos de eficacia refiriéndose tanto a lo cuantitativo como a lo cualitativo.

  5. Beyond the Historical Record? Henry James in “The Master at St. Bartholomew’s Hospital

    Elena Ogliari

    2018-02-01

    Full Text Available The article analyses the short-story “The Master at St Bartholomew’s Hospital 1914–1916” by Joyce Carol Oates (2007 in the broader context of the Jamesian biofiction, a series of novels and tales featuring Henry James as their protagonist. The addition of the prefix “bio-” to “fiction” points out the hybrid nature of these texts, which are a melange of biography, autobiography, criticism and fiction. Oates’s story not only epitomizes this hybridity, but it also proves to be an exploration of the potentiality of this subgenre to penetrate the mystery surrounding James’s persona and saturate the lacunae in his biography by resorting to what David Lodge defined as “the novelist’s licence”. The short-story is yet another evidence of Oates’s fascination with the unsaid in James’s life and prose, because it revolves around the silence into which he sank at the outbreak of the Great War, when he did not write anything in his pocket diaries for three months. In an attempt to go beyond the limits of the historical record, Oates gives insights into the mind of the author by depicting a Henry James in crisis – nagged by doubts about his artistic legacy – in an atmosphere of uncertainty enhanced by a complex intertextual play. The result is ‘a Henry James’ slightly divergent from the historical one: thus, the tale advocates the inaccessibility of the private life of a real individual. Nonetheless, the acknowledgement of this limit spurs the celebration of fictional imagination.

  7. Abraham Pais Prize for History of Physics Talk: Henry Cavendish, John Michell, Weighing the Stars

    McCormmach, Russell

    2010-03-01

    This talk is about an interaction between two 18th-century natural philosophers (physical scientists), Henry Cavendish and John Michell, and its most important outcome, the experiment of weighing the world (their name for it) using a torsion balance (our name for it). Michell was the most inventive of the 18th century English natural philosophers, and Cavendish was the first of his countrymen to possess abilities at all comparable with Newton's. By their interests and skills, they were drawn to one another. Both were universal natural philosophers, equally adept at building scientific instruments, performing experiments, constructing theory, and using mathematics; both had a penchant for exacting, quantitative work. Both also had fitful habits of publication, which did not begin to reveal the range of their work, to the mystification of later scientists and historians. Late in life, Cavendish and Michell turned their attention to the force that Newton had examined most completely, a singular triumph of his natural philosophy, the force of universal gravitation. Over the course of the 18th century, abundant evidence of attraction had been gathered from the motions of the earth, moon, planets, and comets, phenomena which span the intermediate range of masses, sizes, and distances. But in three domains of experience, involving the extreme upper and lower limits of masses and dimensions, the universality of gravitation remained an article of faith. These were the gravity of the ``fixed'' stars, the mutual attraction of terrestrial bodies, and the gravitation of light and other special substances. Michell took on himself the task of deducing observable consequences from each of these prospective instances of universal gravitation. Cavendish encouraged Michell, and he followed up the resulting observational and experimental questions. The experiment of weighing the world was the last experiment Mitchell planned and the last experiment Cavendish published. The capstone of

  8. Controls on sediment cover in bedrock-alluvial channels of the Henry Mountains, Utah

    Hodge, R. A.; Yager, E.; Johnson, J. P.; Tranmer, A.

    2017-12-01

    The location and extent of sediment cover in bedrock-alluvial channels influences sediment transport rates, channel incision and instream ecology. However, factors affecting sediment cover and how it responds to changes in relative sediment supply have rarely been quantitatively evaluated in field settings. Using field surveys and SFM analysis of channel reach topography, we quantified sediment cover and channel properties including slope, width, grain size distributions, and bedrock and alluvial roughness in North Wash and Chelada Creek in the Henry Mountains, Utah. Along reaches where upstream sediment supply does not appear to be restricted, we find that the fraction of local bedrock exposure increases as a function of local relative transport capacity . In a downstream section of Chelada Creek, decadal-scale sediment supply has been restricted by an upstream culvert that has caused a backwater effect and corresponding upstream deposition. In this section, alluvial cover is uncorrelated with local stream power. To test the impact of relative sediment supply on sediment cover, a 1D sediment transport model was used to predict the equilibrium sediment cover in Chelada Creek under varying flow and sediment supply conditions. Sediment transport in each model section was predicted using the partial cover model of Johnson (2015), which accounts for differences in bedrock and alluvial roughness on critical shear stress and flow resistance. Model runs in which sediment supply was approximately equal to mean transport capacity produced a pattern of sediment cover which best matched the field observations upstream of the culvert. However, runs where sediment supply was under-capacity produced the pattern most similar to field observations downstream of the culvert, consistent with our field-based interpretations. Model results were insensitive to initial sediment cover, and equilibrium was relatively quickly reached, suggesting that the channel is responsive to changes in

  9. [Henri Ellenberger, Henri Ey and the Traité de Psychiatrie in the "Encyclopédie Médico-Chirurgicale": an American career under the auspices of the "Evolution Psychiatrique"].

    Delille, Emmanuel

    2006-01-01

    Henri Ellenberger, psychiatrist and historian, experienced a decisive period in his career in the early fifties of the last century. Educated in France, intern at Sainte-Anne Hospital, he was working in Switzerland after the war and then tried to move to the United States. It was during his participation in the French group "l'Evolution Psychiatrique" that he happened to contribute to the treatise of psychiatry (1955) of the French medical and surgical encyclopaedia ("EMC") and organise an observation trip to the United States. He was supported at that time by Henri Ey, key figure of French psychiatry. While going back to his career, we would like to emphasise on his comments about the "Psychotherapy of schizophrenia". Even though later Ellenberger became a well-known researcher in North America, it is more a question for us to discuss the scientific ambition he had in this particular context of a French learned society as a member of "l'Evolution Psychiatrique" and as a psychiatrist formerly intern from the "Hôpitaux psychiatriques de la Seine" (Parisian district).

  11. The Paradox of Being a Wounded Healer: Henri J.M. Nouwen’s Contribution to Pastoral Theology

    S. Philip Nolte

    2010-11-01

    Full Text Available This article is the first in a series of two dealing with Henri Nouwen’s contribution to pastoral care. The present article focuses on the impact of cognitive dissonance and the role it plays in pastors becoming constrained in their ministry. The point of departure is that during the past two decades, pastors have been subjected to profound changes. While pastors view their involvement with people in the social and faith communities in which they live and work as guiding people towards a life of wholeness and integrity, they themselves, because of their own inner woundedness, struggle to live a life of wholeness. This article investigates how pastors can act congruently and with integrity in a world that has been profoundly changed by a shift from a modern to a postmodern paradigm. This reflection explores the ancient Greek mythological origins of the concept ‘wounded healer’. It also shows that, in its utilisation by the Swiss psychiatrist Carl Jung, the concept became a metaphor. This insight leads to a discussion of how Henri Nouwen applied the significance of the metaphor to pastoral ministry. The discussion takes on the form of certain relevant biographical side notes on Nouwen’s contribution to pastoral theology. The article concludes with an exposition of Nouwens’s use of the metaphor in his book, The wounded healer: Ministry in contemporary society.

  14. Let us keep observing and play in sand boxes (Henry Darcy Medal Lecture)

    Illangasekare, T. H.

    2012-04-01

    Henry Darcy was a civil engineer recognized for a number of technical achievements and scientific discoveries. The sand column experiments for which he is known revealed the linear relationship that exists between fluid motion and driving forces at low velocities. Freeze and Back (1983) stated, ''The experiments carried out by Darcy with the help of his assistant, Ritter, in Dijon, France in 1855 and 1856 represent the beginning of groundwater hydrology as a quantitative science." Because of the prominence given to this experiment, two important facts behind Darcy's contributions to subsurface hydrology have not received much attention. First, Darcy was not only a good engineer, but he was also a highly respected scientist whose knowledge of both the fundamentals of fluid mechanics and the natural world of geology led to better conceptualizing and quantifying of groundwater processes at relevant scales to solve practical problems. The experiments for which he is known may have already been conceived, based on his theoretical understanding, and the results were anticipated (Brown 2002). Second, Darcy, through his contributions with Dupuit, showed that they understood hydrologeology at a regional scale and developed methods for quantification at the scale of geologic stratum (Ritz and Bobek, 2008). The primary thesis of this talk is that scientific contributions such as the one Darcy made require appreciation and a thorough understanding of fundamental theory coupled with observation and recording of phenomena both in nature and in the laboratory. Along with all of the significant theoretical, mathematical modeling, and computational advances we have made in the last several decades, laboratory experiments designed to observe phenomena and processes for better insight, accurate data generation, and hypothesis development are critically important to make scientific and engineering advances to address some of the emerging and societally important problems in hydrology

  15. Henry Hub and national balancing point prices: what will be the international gas price reference?

    Mazighi, A.E.H.

    2005-01-01

    One of the lessons in the history of international trade in commodities is the emergence - sooner or later - of an international price reference, most commonly known as an international marker price. In the area of oil, West Texas Intermediate (WTI) plays the role of a marker for sour crudes traded in the Atlantic basin. Brent oil fulfils this function for sweet crudes traded in Europe. Another important aspect in the area of global commodities is that the emergence of a marker price is not always necessarily related to the relative share of production of exports of the commodity, but primarily to the existence of an organized market for this commodity. Today, while international gas trade is intensifying, we still lack an international price reference for this commodity. This is due to the fact that the international trade of natural gas is still highly regionalized. It is also due to the fact that most gas markets are still regulated. Nevertheless, deregulation efforts have been implemented in both developed (the United States, the United Kingdom, continental Europe, Korea) and developing countries (Brazil, Chile) and have led to new market structures based on more competition in all segments of the gas chain, except transportation. In the meantime, price structures based on supply and demand principles are supposed to have emerged in the US and UK markets in the 1990s as a result of the implementation of deregulation measures. Today, the US gas market, which represents more than 660 billion cubic metres per year of consumption and the UK gas market, which is close to 100 bcm annually, are considered mature enough to make the principles of supply and demand operate inside these markets. In fact, the Henry Hub (HH) price, which is determined at a physical location in Louisiana, US, and the national balancing point (NBP) price, which is determined somewhere inside the national transmission system (NTS), without any precise location, are considered as potential

  1. From the "metaphysics of the individual" to the critique of society: on the practical significance of Michel Henry's phenomenology of life.

    Staudigl, Michael

    This essay explores the practical significance of Michel Henry's "material phenomenology." Commencing with an exposition of his most basic philosophical intuition, i.e., his insight that transcendental affectivity is the primordial mode of revelation of our selfhood, the essay then brings to light how this intuition also establishes our relation to both the world and others. Animated by a radical form of the phenomenological reduction, Henry's material phenomenology brackets the exterior world in a bid to reach the concrete interior transcendental experience at the base of all exteriority. The essay argues that this "counter reduction," designed as a practical orientation to the world, suspends all traditional parameters of onto(theo)logical individuation in order to rethink subjectivity in terms of its transcendental corporeality, i.e., in terms of the invisible display of "affective flesh." The development of this "metaphysics of the individual" anchors his "practical philosophy" as he developed it-under shifting accents-throughout his oeuvre. In particular, the essay brings into focus Henry's reflections on modernity, the industry of mass culture and their "barbaric" movements. The essay briefly puts these cultural and political areas of Henry's of thinking into contact with his late "theological turn," i.e., his Christological account of Life and the (inter)subjective self-realization to which it gives rise.

  2. [The electric furnace of Henri Moissan at one hundred years: connection with the electric furnace, the solar furnace, the plasma furnace?].

    Royère, C

    1999-03-01

    The trace of Henri Moissan's pioneer work 100 years ago is clearly evidenced by an overview of achievements in high temperature devices; 1987: "Le four électrique" by Henri Moissan; 1948-1952: "High temperature heating in a cavity rotary kiln using focusing of solar radiation" by Félix Trombe; 1962: "The cavity rotary kiln using focused solar radiation jointly with a plasma gun" by Marc Foëx; 1970: "The rotary kiln with two plasma guns and arc transfer" by Marc Foëx; 1984: "The plasma furnace" by Electricité de France (EDF) at Renardières; 1997: "The plasma furnace" by the Atomic Energy Center (CEA) at Cadarache, the VULCANO program. The first part of this contribution is devoted to Henri Moissan. Re-reading his early book on the electric furnace, especially the first chapter and the sections on silica, carbon vapor and experiments performed in casting molten metal--the conclusions are outstanding--provides modern readers with an amazing insight into future developments. The last two parts are devoted to Félix Trombe and Marc Foëx, tracing the evolution of high temperature cavity processus leading to the solar furnace and the present day plasma furnace at the CEA. Focus is placed on research conducted by the French National Center for Scientific Research (CNRS) with the solar and plasma furnaces at Odeillo. The relationships with Henri Moissan's early work are amazing, offering a well deserved homage to this pioneer researcher.

    2018-03-01

    In London, November 1915, a telegram was received at the home of William Henry Bragg from the secretary of the Academy of Science in Stockholm announcing the award of the Nobel Prize in Physics for "the analysis of crystal structures by means of X-rays". A second similar telegram was addressed to his 25 year old son William Lawrence Bragg (Jenkin, 2008). This article commemorates the centenary of that event and the unveiling of a bust of Sir William Bragg alongside that of his son, Sir Lawrence Bragg, on North Terrace in Adelaide where he spent 23 years of his early career.

  7. Promoting good health in the age of reform: the medical publications of Henry H. Porter of Philadelphia, 1829-32.

    Horrocks, T A

    1995-01-01

    In the early 1830s, the Philadelphia publisher Henry H. Porter rapidly published five journals, six books, and an almanac, works having a particular emphasis on health and personal hygiene. Porter's health publications linked the traditional message about the importance of personal hygiene to health to the messages conveyed by the flourishing American reform movements at the time, and his Journal of Health was among the first American medically oriented periodicals published for the layperson. Yet Porter did not survive in the intensely competitive and financially unstable book trade. This study examines Porter's health publications, attempting to explain why he chose to publish what he did, the message(s) his works contained, the audience(s) he tried to reach, and the failure of his business.

  9. Henry Currey FRIBA (1820-1900): leading Victorian hospital architect, and early exponent of the "pavilion principle".

    Cook, G C

    2002-06-01

    The "pavilion plan" for hospital design originated in France in the 18th century and was popularised in England by John Roberton and George Godwin in the mid-19th century; the underlying rationale was that with improved ventilation the mortality rate (at that time exceedingly high) was significantly reduced. Among the enthusiasts for this new style was Florence Nightingale (herself a miasmatist)--who had experienced astronomically high death rates in the hospital at Scutari during the Crimean War (1854-6). One of the leading exponents of this style of hospital architecture was Henry Currey (1820-1900) whose greatest achievement was undoubtedly the design for the new St Thomas's Hospital on the Lambeth Palace Road.

  10. Polyphony and counterpoint: Mechanisms of seduction in the diaries of Helen Hessel and Henri Pierre Roché

    Catherine du Toit

    2015-06-01

    Polifonie en kontrapunt: Meganismes van verleiding in die dagboeke van Helen Hessel en Henri Pierre Roché. Henri Pierre Roché (1879–1959, outeur van Jules et Jim, word beskryf as ‘n sosiale koppelaar, ‘n model-liefhebber van alles en nog wat, ‘n versamelaar van vroue en kuns en een van die mees produktiewe dagboekskrywers en aktiewe minnaars in die opgetekende geskiedenis. Roché het ‘n reeks sketse oor Don Juan gepubliseer en was geboei deur die figuur van die verleier. In sy twintigs beplan hy om sy lewe te wy aan die skepping van ‘n œuvre wat die morele, intellektuele, sosiale en seksuele verhoudings tussen mans en vrouens sou ondersoek. Ter bereiking van hierdie doel, rig hy sy lewe in as laboratorium waarin werklike ondervindinge dien as hoofbron van inligting. Sy dagboek strek oor sestig jaar en is ryk aan verhale van verleiding. Desnieteenstaande bly die mees intense en boeiende intrige van verleiding en verraad steeds sy verhouding met Helen Hessel. Aan die begin van hulle verhouding, stel Roché voor dat sy ook ‘n dagboek hou van hulle hartstogtelike liefde. Helen Hessel se dagboek, geskryf in Frans, Duits en Engels, reflekteer die drama van verleiding en funksioneer op verskillende vlakke: realisties, visionêr, ten volle geabsorbeer in haar eie gedagtes en emosies en tóg krities jeens haarself en ander. ‘n Vergelyking van die twee dagboeke skep ‘n fassinerende, digte tekstuur wat die binnewerkings blootlê van verleiding in aksie. Die kontrapunt geskep deur hierdie twee interafhanklike stemme word nóg meer kompleks namate ‘n mens bewus word van die intertekstuele verwysings wat bydra tot die ontluikende polifonie van geskrewe liefde en lewe.

  18. Determination of Henry's constant, the dissociation constant, and the buffer capacity of the bicarbonate system in ruminal fluid.

    Hille, Katharina T; Hetz, Stefan K; Rosendahl, Julia; Braun, Hannah-Sophie; Pieper, Robert; Stumpff, Friederike

    2016-01-01

    Despite the clinical importance of ruminal acidosis, ruminal buffering continues to be poorly understood. In particular, the constants for the dissociation of H2CO3 and the solubility of CO2 (Henry's constant) have never been stringently determined for ruminal fluid. The pH was measured in parallel directly in the rumen and the reticulum in vivo, and in samples obtained via aspiration from 10 fistulated cows on hay- or concentrate-based diets. The equilibrium constants of the bicarbonate system were measured at 38°C both using the Astrup technique and a newly developed method with titration at 2 levels of partial pressure of CO2 (pCO2; 4.75 and 94.98 kPa), yielding mean values of 0.234 ± 0.005 mmol ∙ L(-1) ∙ kPa(-1) and 6.11 ± 0.02 for Henry's constant and the dissociation constant, respectively (n/n = 31/10). Both reticular pH and the pH of samples measured after removal were more alkalic than those measured in vivo in the rumen (by ΔpH = 0.87 ± 0.04 and 0.26 ± 0.04). The amount of acid or base required to shift the pH of ruminal samples to 6.4 or 5.8 (base excess) differed between the 2 feeding groups. Experimental results are compared with the mathematical predictions of an open 2-buffer Henderson-Hasselbalch equilibrium model. Because pCO2 has pronounced effects on ruminal pH and can decrease rapidly in samples removed from the rumen, introduction of a generally accepted protocol for determining the acid-base status of ruminal fluid with standard levels of pCO2 and measurement of base excess in addition to pH should be considered.

    2016-01-01

    Full Text Available En este ensayo resaltamos los vínculos cognitivos entre las matemáticas y la música, que pueden favorecer procesos de enseñanza y aprendizaje de las fracciones en la matemática escolar. Las actividades exhibidas provienen de una investigación que promueve experiencias sensoriales en el campo rítmico para favorecer la construcción de nociones matemáticas. Dichas actividades posibilitan un engranaje armónico entre las matemáticas y la música convergentes en el tiempo y el sonido como los objetos de estudio común entre éstas disciplinas. El análisis de la investigación que aquí reportamos es producto de la aplicación de las actividades en diferentes programas de formación de profesorado de México y Francia, alrededor de la enseñanza y aprendizaje de las matemáticas en contextos interdisciplinarios. Este análisis se desarrolló desde tres categorías referentes a las nociones de unidad relativa, relación parte-parte y equipartición, las cuales son nociones fundamentales para el estudio de las fracciones en la matemática escolar. Encontramos que la enseñanza con enfoque integrador requiere no solo conocimientos especializados, sino un cambio de creencias en torno a las opiniones del profesorado sobre la organización del currículo, su enseñanza y la manera en que aprende la población estudiantil. Un aporte de esta experiencia es ofrecer a docentes elementos teóricos y didácticos para el estudio de las fracciones en contextos interdisciplinarios.

    Erika Cazzonatto Zerwes

    2016-08-01

    Full Text Available This article aims to grasp some aspects of the notion of humanism in photography and its closeness to the political culture and the visual culture in the period, through the specific experiences of George Rodger and Henri Cartier-Bresson, two photographers who were first-hand witnesses and provided accounts of horror in the Nazi concentration camps at the end of World War II. George Rodger photographed the Bergen-Belsen camp as soon as it was liberated by the British troops. Henri Cartier-Bresson was there with a film crew recording the deported masses newly freed from the Nazi concentration and extermination camps. These experiences came to have profound impact on the biography and work of both of them. In the two cases, there is a notion of humanism linked to World War II events, which is observed in photography and photographic representation, and it has a significant consequence for the contemporary visual culture.   Keywords: Visual Culture; Political Culture; War Photography; Photojournalism; Concentration Camps.   Original title: O humano e o desumano: cultura visual, cultura política e as imagens feitas por George Rodger e Henri Cartier-Bresson nos campos de concentração nazistas.

  15. Daily Management System of the Henry Ford Production System: QTIPS to Focus Continuous Improvements at the Level of the Work.

    Zarbo, Richard J; Varney, Ruan C; Copeland, Jacqueline R; D'Angelo, Rita; Sharma, Gaurav

    2015-07-01

    To support our Lean culture of continuous improvement, we implemented a daily management system designed so critical metrics of operational success were the focus of local teams to drive improvements. We innovated a standardized visual daily management board composed of metric categories of Quality, Time, Inventory, Productivity, and Safety (QTIPS); frequency trending; root cause analysis; corrective/preventive actions; and resulting process improvements. In 1 year (June 2013 to July 2014), eight laboratory sections at Henry Ford Hospital employed 64 unique daily metrics. Most assessed long-term (>6 months), monitored process stability, while short-term metrics (1-6 months) were retired after successful targeted problem resolution. Daily monitoring resulted in 42 process improvements. Daily management is the key business accountability subsystem that enabled our culture of continuous improvement to function more efficiently at the managerial level in a visible manner by reviewing and acting based on data and root cause analysis.

Although diverse in intent, many of these were undertaken in the interests of furthering colonial territorial claims. In 1900-1901, Major Herbert Henry Austin led a British expedition down to the lake from Khartoum in the north. Of the 62 African, Arab, and European members of this expedition, only 18 (29 %) arrived at its final destination at Lake Baringo in Kenya. Because of a confluence of adverse climatic, social, and political conditions, the expedition ran short of food supplies when it arrived at the northern end of the lake in April 1901. For the next 4 months, the members of the expedition struggled down the west side of the lake and beyond. The greatest mortality (91 %) occurred among the 32 African transport drivers who were the most marginally nourished at the outset of the trip. The lowest mortality among the Africans on the expedition (15 %) occurred among the members of the Tenth Sudanese Rifles Battalion, who had an excellent nutritional status at the start of the expedition. Major Austin himself suffered from severe scurvy with retinal hemorrhages which left him partially blind in his right eye. An analysis of the mortality rates among the groups that participated in this expedition was undertaken. This revealed that poor nutritional status at the start of the trip was predictive of death from starvation.

    To develop a business subsystem fulfilling International Organization for Standardization 15189 nonconformance management regulatory standard, facilitating employee engagement in problem identification and resolution to effect quality improvement and risk mitigation. From 2012 to 2016, the integrated laboratories of the Henry Ford Health System used a quality technical team to develop and improve a management subsystem designed to identify, track, trend, and summarize nonconformances based on frequency, risk, and root cause for elimination at the level of the work. Programmatic improvements and training resulted in markedly increased documentation culminating in 71,641 deviations in 2016 classified by a taxonomy of 281 defect types into preanalytic (74.8%), analytic (23.6%), and postanalytic (1.6%) testing phases. The top 10 deviations accounted for 55,843 (78%) of the total. Deviation management is a key subsystem of managers' standard work whereby knowledge of nonconformities assists in directing corrective actions and continuous improvements that promote consistent execution and higher levels of performance. © American Society for Clinical Pathology, 2017.

  18. Urban common space, heterotopia and the right to the city: Reflections on the ideas of Henri Lefebvre and David Harvey

    Orlando Alves dos Santos Junior

    2014-05-01

    Full Text Available A city’s common spaces are appropriated by capital that aims to guarantee the conditions necessary for the production-reproduction of capitalist relations. In this context, the challenge is to imagine and construct a very different type of city capable of breaking away from the dynamic of capital, founded on new forms of appropriation of the city, which implies articulating both theory and praxis. For this to occur, however, it is necessary to create new knowledge about the city and a strong anti-capitalist social movement focused on the transformation of daily urban life and involving new forms of appropriation of urban common spaces. It is in this context, and from a dialectic perspective, that this article articulates the ideas of Henri Lefebvre and David Harvey, seeking to contribute to an understanding of the production processes of space in contemporary capitalism, the discussion of the future of cities and perspectives on transition. To do so, the article addresses four central ideas: (i the dialectic conception of space to problematize the production and appropriation of urban common spaces; (ii the recognition of urban common spaces as spaces traversed by contradictions, disputes and material and symbolic conflicts among different agents; (iii the right to the city as a need and as a utopian project; and (iv the challenge of articulating heterotopic practices from the perspective of creative rebellion for the right to the city and the transition to a new urban future.

  19. Multilayer, Stacked Spiral Copper Inductors on Silicon with Micro-Henry Inductance Using Single-Level Lithography

    2012-01-01

    Full Text Available We present copper structures composed of multilayer, stacked inductors (MLSIs with tens of micro-Henry inductance for use in low frequency (sub 100 MHz, power converter technology. Unique to this work is the introduction of single-level lithography over the traditional two-level approach to create each inductor layer. The result is a simplified fabrication process which results in a reduction in the number of lithography steps per inductor (metal layer and a reduction in the necessary alignment precision. Additionally, we show that this fabrication process yields strong adhesion amongst the layers, since even after a postprocess abrasion technique at the inner diameter of the inductors, no shearing occurs and connectivity is preserved. In total, three separate structures were fabricated using the single-level lithography approach, each with a three-layered, stacked inductor design but with varied geometries. Measured values for each of the structures were extracted, and the following results were obtained: inductance values of 24.74, 17.25, and 24.74 μH, self-resonances of 9.87, 5.72, and 10.58 MHz, and peak quality factors of 2.26, 2.05, and 4.6, respectively. These values are in good agreement with the lumped parameter model presented.

  1. Architectural creativity of Alexander Bernardazzi and Henry Lonsky in Kishinev during the second half of the XIXth century

    2017-10-01

    Full Text Available During the period following 1873, when Bessarabia was a province of the Russian Empire, the architecture of this period was dominated by a mixture of several historical styles and directions, the so-called “eclectic” stage. The creativity of leading architects such as Alexander Bernardazzi and Henry Lonsky was the most evident at that time. The image of the city of Kishinev became more eclectic and it was reflected in the buildings of the railway station and the passenger hall, the city club, the county court, the Noble Assembly, the winemaking school, all of which were built according to the designs of these architects in the second half of the XIX century. At that time, a question relative to the necessity of new theatre building in Kishinev was of a particular interest. In 1889 the Kishinev City Head Karl Schmidt proposed to construct a temporary theatre with beautiful facade, together with the fact that in size it could satisfy the needs of city for the next 15-20 years. And he appealed to the city architects, including A. Bernardazzi and H. Lonsky to present their views at this important problem. The author writes this article on the basis of the archival documents which present the history of the construction of various buildings and the creative activity of the architects. This is reflected through the prism of that era with a high level of development and methods of construction equipment, as well as with the artistic principles characteristic of that period.

  3. Inverse modeling for seawater intrusion in coastal aquifers: Insights about parameter sensitivities, variances, correlations and estimation procedures derived from the Henry problem

    Sanz, E.; Voss, C.I.

    2006-01-01

    Inverse modeling studies employing data collected from the classic Henry seawater intrusion problem give insight into several important aspects of inverse modeling of seawater intrusion problems and effective measurement strategies for estimation of parameters for seawater intrusion. Despite the simplicity of the Henry problem, it embodies the behavior of a typical seawater intrusion situation in a single aquifer. Data collected from the numerical problem solution are employed without added noise in order to focus on the aspects of inverse modeling strategies dictated by the physics of variable-density flow and solute transport during seawater intrusion. Covariances of model parameters that can be estimated are strongly dependent on the physics. The insights gained from this type of analysis may be directly applied to field problems in the presence of data errors, using standard inverse modeling approaches to deal with uncertainty in data. Covariance analysis of the Henry problem indicates that in order to generally reduce variance of parameter estimates, the ideal places to measure pressure are as far away from the coast as possible, at any depth, and the ideal places to measure concentration are near the bottom of the aquifer between the center of the transition zone and its inland fringe. These observations are located in and near high-sensitivity regions of system parameters, which may be identified in a sensitivity analysis with respect to several parameters. However, both the form of error distribution in the observations and the observation weights impact the spatial sensitivity distributions, and different choices for error distributions or weights can result in significantly different regions of high sensitivity. Thus, in order to design effective sampling networks, the error form and weights must be carefully considered. For the Henry problem, permeability and freshwater inflow can be estimated with low estimation variance from only pressure or only

  5. Do gesto ao símbolo: a teoria de Henri Wallon sobre a formação simbólica From gesture to symbol: the theory of Henri Wallon about symbolic formation

    Dener Luiz da Silva

    2007-01-01

    Full Text Available Henri Wallon, filósofo, médico e psicólogo francês, contribuiu para a psicologia não apenas com uma teoria da emoção ou ainda com suas discussões e divergências com Jean Piaget. Dentre suas contribuições pouco discutidas estão sua teoria sobre a inteligência, suas discussões sobre a origem e o desenvolvimento do pensamento discursivo nas crianças e, talvez menos conhecidas, suas reflexões e proposições sobre a transição entre uma inteligência sensório-motora (caracterizada pela capacidade de resolver problemas práticos, mas sem o auxílio da reflexão e uma outra, inteligência discursiva (caracterizada pela utilização e intermediação dos símbolos e representações. Sabe-se que sua proposição para essa transição, diversamente de Piaget, que ressalta a continuidade e a preparação do simbólico pelo esquematismo sensório-motor, é marcada justamente pela não continuidade entre uma inteligência e outra, pela intromissão de fatores externos tais como a cultura, o social e a linguagem, e pela complexa interação entre todos esses fatores. Para melhor compreender a proposta walloniana sobre a formação do símbolo é necessário, pois, que ingressemos na sua teoria como um todo, buscando decifrar seus conceitos de emoção, comportamento simbólico, inteligência, fatores de desenvolvimento e outros. Em uma sociedade como a nossa, baseada no comportamento simbólico, entender como se dá, qual a origem e o desenvolvimento do pensamento simbólico podem ser conhecimentos de grande valia.Henri Wallon, French philosopher, physician, and psychologist, has given psychology contribution not only with his emotion theory and with his arguments and disagreements with Jean Piaget.

    From June 1986 to December 1996, 643 patients presenting with acquired immunodeficiency syndrome (AIDS)-related epidemic Kaposi`s sarcoma were treated with irradiation at the Oncology Department of Henri Mondor University Hospital. Three-hundred eighty-seven patients (60 %) had previously received a treatment with interferon (259 patients, 40.2 %), vinblastine (225 patients, 34.5 %), doxorubicin (22 patients, 3.4 %), bleomycin (19 patients, 2.9 %), and/or antiviral treatment (216, 33.5 %). The radiotherapy was delivered by 4 MeV OR 8 MeV electron beam for extended cutaneous fields and 45-100 kV x-ray for localized fields. The delivered dose was 20 Gy in 2 weeks (2.5 Gy/fraction, 4 fractions/week) followed by 2 weeks rest and second series of 10 Gy in 1 week. For oral cavity lesions, we used a series of 15.2 Gy was delivered (1.9 Gy/fraction, 4 fractions/week), followed for three patients by a 3 week rest and by a similar second series of 15.2 Gy.Six-hundred and twenty-one patients were evaluable and the objective response rate was 92 %, with e complete regression of clinical and functional symptoms for all patients. The skin tolerance was good, with 7.3 % grade I reactions, 69.3 % of grade II reactions, and 23.4 % grade III reactions. There was a correlation between recurrence rate and the occurrence of opportunistic infections. This analysis shows the efficacy of dose radiotherapy for treatment of epidemic Kaposi sarcoma.

    Machine learning is becoming a popular and important approach in the field of medical research. In this study, we investigate the relative performance of various machine learning methods such as Decision Tree, Naïve Bayes, Logistic Regression, Logistic Model Tree and Random Forests for predicting incident diabetes using medical records of cardiorespiratory fitness. In addition, we apply different techniques to uncover potential predictors of diabetes. This FIT project study used data of 32,555 patients who are free of any known coronary artery disease or heart failure who underwent clinician-referred exercise treadmill stress testing at Henry Ford Health Systems between 1991 and 2009 and had a complete 5-year follow-up. At the completion of the fifth year, 5,099 of those patients have developed diabetes. The dataset contained 62 attributes classified into four categories: demographic characteristics, disease history, medication use history, and stress test vital signs. We developed an Ensembling-based predictive model using 13 attributes that were selected based on their clinical importance, Multiple Linear Regression, and Information Gain Ranking methods. The negative effect of the imbalance class of the constructed model was handled by Synthetic Minority Oversampling Technique (SMOTE). The overall performance of the predictive model classifier was improved by the Ensemble machine learning approach using the Vote method with three Decision Trees (Naïve Bayes Tree, Random Forest, and Logistic Model Tree) and achieved high accuracy of prediction (AUC = 0.92). The study shows the potential of ensembling and SMOTE approaches for predicting incident diabetes using cardiorespiratory fitness data.

  9. In-cloud multiphase behaviour of acetone in the troposphere: gas uptake, Henry's law equilibrium and aqueous phase photooxidation.

    Acetone is ubiquitous in the troposphere. Several papers have focused in the past on its gas phase reactivity and its impact on tropospheric chemistry. However, acetone is also present in atmospheric water droplets where its behaviour is still relatively unknown. In this work, we present its gas/aqueous phase transfer and its aqueous phase photooxidation. The uptake coefficient of acetone on water droplets was measured between 268 and 281K (γ=0.7 x 10(-2)-1.4 x 10(-2)), using the droplet train technique coupled to a mass spectrometer. The mass accommodation coefficient α (derived from γ) was found in the range (1.0-3.0±0.25) x 10(-2). Henry's law constant of acetone was directly measured between 283 and 298K using a dynamic equilibrium system (H((298K))=(29±5)Matm(-1)), with the Van't Hoff expression lnH(T)=(5100±1100)/T-(13.4±3.9). A recommended value of H was suggested according to comparison with literature. The OH-oxidation of acetone in the aqueous phase was carried out at 298K, under two different pH conditions: at pH=2, and under unbuffered conditions. In both cases, the formation of methylglyoxal, formaldehyde, hydroxyacetone, acetic acid/acetate and formic acid/formate was observed. The formation of small amounts of four hydroperoxides was also detected, and one of them was identified as peroxyacetic acid. A drastic effect of pH was observed on the yields of formaldehyde, one hydroperoxide, and, (to a lesser extent) acetic acid/acetate. Based on the experimental observations, a chemical mechanism of OH-oxidation of acetone in the aqueous phase was proposed and discussed. Atmospheric implications of these findings were finally discussed. Copyright © 2010 Elsevier Ltd. All rights reserved.

  11. Temperature dependencies of Henry's law constants and octanol/water partition coefficients for key plant volatile monoterpenoids.

    Copolovici, Lucian O; Niinemets, Ulo

    2005-12-01

    To model the emission dynamics and changes in fractional composition of monoterpenoids from plant leaves, temperature dependencies of equilibrium coefficients must be known. Henry's law constants (H(pc), Pa m3 mol(-1) and octanol/water partition coefficients (K(OW), mol mol(-1)) were determined for 10 important plant monoterpenes at physiological temperature ranges (25-50 degrees C for H(pc) and 20-50 degrees C for K(OW)). A standard EPICS procedure was established to determine H(pc) and a shake flask method was used for the measurements of K(OW). The enthalpy of volatilization (deltaH(vol)) varied from 18.0 to 44.3 kJ mol(-1) among the monoterpenes, corresponding to a range of temperature-dependent increase in H(pc) between 1.3- and 1.8-fold per 10 degrees C rise in temperature. The enthalpy of water-octanol phase change varied from -11.0 to -23.8 kJ mol(-1), corresponding to a decrease of K(OW) between 1.15- and 1.32-fold per 10 degrees C increase in temperature. Correlations among physico-chemical characteristics of a wide range of monoterpenes were analyzed to seek the ways of derivation of H(pc) and K(OW) values from other monoterpene physico-chemical characteristics. H(pc) was strongly correlated with monoterpene saturated vapor pressure (P(v)), and for lipophilic monoterpenes, deltaH(vol) scaled positively with the enthalpy of vaporization that characterizes the temperature dependence of P(v) Thus, P(v) versus temperature relations may be employed to derive the temperature relations of H(pc) for these monoterpenes. These data collectively indicate that monoterpene differences in H(pc) and K(OW) temperature relations can importantly modify monoterpene emissions from and deposition on plant leaves.

  12. A Generalized Semi-Analytical Solution for the Dispersive Henry Problem: Effect of Stratification and Anisotropy on Seawater Intrusion

    Marwan Fahs

    2018-02-01

    Full Text Available The Henry problem (HP continues to play a useful role in theoretical and practical studies related to seawater intrusion (SWI into coastal aquifers. The popularity of this problem is attributed to its simplicity and precision to the existence of semi-analytical (SA solutions. The first SA solution has been developed for a high uniform diffusion coefficient. Several further studies have contributed more realistic solutions with lower diffusion coefficients or velocity-dependent dispersion. All the existing SA solutions are limited to homogenous and isotropic domains. This work attempts to improve the realism of the SA solution of the dispersive HP by extending it to heterogeneous and anisotropic coastal aquifers. The solution is obtained using the Fourier series method. A special hydraulic conductivity–depth model describing stratified heterogeneity is used for mathematical convenience. An efficient technique is developed to solve the flow and transport equations in the spectral space. With this technique, we show that the HP can be solved in the spectral space with the salt concentration as primary unknown. Several examples are generated, and the SA solutions are compared against an in-house finite element code. The results provide high-quality data assessed by quantitative indicators that can be effectively used for code verification in realistic configurations of heterogeneity and anisotropy. The SA solution is used to explain contradictory results stated in the previous works about the effect of anisotropy on the saltwater wedge. It is also used to investigate the combined influence of stratification and anisotropy on relevant metrics characterizing SWI. At a constant gravity number, anisotropy leads to landward migration of the saltwater wedge, more intense saltwater flux, a wider mixing zone and shallower groundwater discharge zone to the sea. The influence of stratified heterogeneity is more pronounced in highly anisotropic aquifers. The

    Astrid Deuber-Mankowsky

    2017-01-01

    In his lecture series The Four Fundamental Concepts of Psychoanalysis (1964), Lacan refers to a “delightful example” that Merleau-Ponty gives in his Book Signes (1960). Lacan describes it as a “strange slow-motion film in which one sees Matisse painting.” This is a scene from the documentary entitled A Great French Painter, Henri Matisse, by director François Campaux, a 16mm black and white film shot in 1946. Merleau-Ponty points, as Lacan puts it, to “the paradox of that gesture which, enlar...

  5. 'A Speculative Idea': The Parallel Trajectories of Financial Speculation, Obstetrical Science, and Fiscal Management of Female Bodies in Henry James's Washington Square.

    Nixon, Kari

    2017-09-01

    This essay teases out the intimate connections between the scientific and fiscal realms in the context of American germ theory and obstetrics. By uncovering the economic and medical contexts of Henry James's Washington Square-set during the infancy of germ theory and the heyday of American obstetrics-this essay exposes a previously unexplored subtextual history of contagion in the text. Although this scientific history seems relegated to the novel's margins, understanding the changing scientific cosmologies and professional organizations in the context of the novel's setting and composition reveals that these tiny infectious particles and their vectors fundamentally shape the plot of the novel.

    Serial killers are important in American horror because of their ability to exist between ‘myth’ and ‘reality’. The serial killer is one of the most important American myths, but it is one firmly rooted in real life: unlike Paul Bunyan or Superman, serial killers do exist. This essay examines the relationship between the ‘myth’ and the ‘reality’ of serial killers, and the complex relationship between the American public and the serial killer, using Henry: Portrait of a Serial K...

    Full Text Available La primera paratiroidectomía exitosa fue realizada en Viena, Austria, en 1925. Los procedimientos laparoscópicos estuvieron inicialmente limitadas a las zonas corporales con cavidades preexistentes, recientemente, el acceso a espacios anatómicos potenciales ha extendido las indicaciones de la cirugía endoscópica minimamnete invasiva.Desde el primer reporte sobre la paratiroidectomía endoscópica en 1996, las técnicas video-asistidas han comenzado a utilizarse en la cirugía del cuello, y en varias series se han documentado la factibilidad y seguridad de este tipo de abordaje. La finalidad de esta investigación fue el determinar la factibilidad, seguridad y eficacia de la paratiroidectomía endoscopia en el modelo canino.Entre el 25 de noviembre del 2005 y 15 de octubre del 2007, se intervinieron en el Instituto de Cirugía Experimental de la Universidad Central de Venezuela 31 perros, mestizos sanos desparasitados,asignándose a dos grupos: homogéneos "A" 16, a cirugía convencional, "B" 15 a cirugía video-asistida. Se midieron las siguientes variables; sexo, peso, exámenes de laboratorio, laringoscopia pre y postoperatoria, posición, dirección de la incisión, longitud, localización, valores pre y postoperatorios de calcio, fósforo, proteína C reactiva, hemoglobina, hematocrito, tipo de disección, número y posición de las paratiroides, identificación de los nervios recurrentes y rama externa del nervio laríngeo superior, sangramiento, dificultades intraoperatorias, tiempo, resultado del estudio histopatológico.Las deducciones de este estudio experimental proporcionan evidencias de que la paratiroidectomía endoscópica es factible y segura. El abordaje mínimo tiene mejores resultados cosméticos y el potencial de disminuir la morbi-mortalidad.

  8. ‘Two Minds With but a Single Thought’: W. T. Stead, Henry James, and the Zancig Controversy

    Paul Horn

    2013-04-01

    Full Text Available In 1906, two writers of disparate repute watched, and then wrote about a series of notorious performances by the London telepathists Julius and Agnes Zancig.One was W. T. Stead, the pugnacious purveyor of New Journalism and hugely influential in shaping public opinion; the other was Henry James, the author of a great number of highbrow, complex, and ultimately poorly selling works of prose fiction.James wrote in a letter of his impression of ‘the 'reality 'of their performance’ in the face of accusations of fraud based on a supposed ‘very wonderfully elaborated code of signalling’ between the pair.A persuasive factor was the rumour, told to him by the actor and theatre manager John Hare at a party, that Stead had proved the Zancigs’ telepathic powers during private tests at his own home.Stead published his own defence of the Zancigs in the 'Review of Reviews',' 'covering in detail their performance at the Alhambra Music Hall, and, indeed, the tests that seem likely to have been the subject of the gossip heard by James.What is especially remarkable about Stead’s article is that its description of the physical reality of telepathy is strikingly reminiscent of the instances of wordless communication that occur between the sensitive protagonists who populate James’s 'fin-de-siècle' novels.The aim of my paper is to use Stead’s and James’s shared interest in the Zancigs as a starting point from which to explore how the two writers’ authorial voices, ostensibly so different to each other, become closely imbricated as they converge on the topic of thought transference.In this way, I hope to show that in addition to the operation of rumour among their social milieu, Stead and James were connected by their appreciation of a more occulted form of communication, which would help define their apparently distinct contributions to 'fin-de-siècle' culture.

  9. A Detailed Geophysical Investigation of the Grounding of Henry Ice Rise, with Implications for Holocene Ice-Sheet Extent.

    Wearing, M.; Kingslake, J.

    2017-12-01

    It is generally assumed that since the Last Glacial Maximum the West Antarctic Ice Sheet (WAIS) has experienced monotonic retreat of the grounding line (GL). However, recent studies have cast doubt on this assumption, suggesting that the retreat of the WAIS grounding line may have been followed by a significant advance during the Holocene in the Weddell and Ross Sea sectors. Constraining this evolution is important as reconstructions of past ice-sheet extent are used to spin-up predictive ice-sheet models and correct mass-balance observations for glacial isostatic adjustment. Here we examine in detail the formation of the Henry Ice Rise (HIR), which ice-sheet model simulations suggest played a key role in Holocene ice-mass changes in the Weddell Sea sector. Observations from a high-resolution ground-based, ice-penetrating radar survey are best explained if the ice rise formed when the Ronne Ice Shelf grounded on a submarine high, underwent a period of ice-rumple flow, before the GL migrated outwards to form the present-day ice rise. We constrain the relative chronology of this evolution by comparing the alignment and intersection of isochronal internal layers, relic crevasses, surface features and investigating the dynamic processes leading to their complex structure. We also draw analogies between HIR and the neighbouring Doake Ice Rumples. The date of formation is estimated using vertical velocities derived with a phase-sensitive radio-echo sounder (pRES). Ice-sheet models suggest that the formation of the HIR and other ice rises may have halted and reversed large-scale GL retreat. Hence the small-scale dynamics of these crucial regions could have wide-reaching consequences for future ice-sheet mass changes and constraining their formation and evolution further would be beneficial. One stringent test of our geophysics-based conclusions would be to drill to the bed of HIR to sample the ice for isotopic analysis and the bed for radiocarbon analysis.

    Time-of-flight secondary ion mass spectrometry (ToF-SIMS) has recently been shown to be a valuable tool for cultural heritage studies, especially when used in conjunction with established analytical techniques in the field. The ability of ToF-SIMS to simultaneously image inorganic and organic species within a paint cross section at micrometer-level spatial resolution makes it a uniquely qualified analytical technique to aid in further understanding the processes of pigment and binder alteration, as well as pigment-binder interactions. In this study, ToF-SIMS was used to detect and image both molecular and elemental species related to CdS pigment and binding medium alteration on the painting Le Bonheur de vivre (1905-1906, The Barnes Foundation) by Henri Matisse. Three categories of inorganic and organic components were found throughout Le Bonheur de vivre and co-localized in cross-sectional samples using high spatial resolution ToF-SIMS analysis: (1) species relating to the preparation and photo-induced oxidation of CdS yellow pigments (2) varying amounts of long-chain fatty acids present in both the paint and primary ground layer and (3) specific amino acid fragments, possibly relating to the painting's complex restoration history. ToF-SIMS's ability to discern both organic and inorganic species via cross-sectional imaging was used to compare samples collected from Le Bonheur de vivre to artificially aged reference paints in an effort to gather mechanistic information relating to alteration processes that have been previously explored using μXANES, SR-μXRF, SEM-EDX, and SR-FTIR. The relatively high sensitivity offered by ToF-SIMS imaging coupled to the high spatial resolution allowed for the positive identification of degradation products (such as cadmium oxalate) in specific paint regions that have before been unobserved. The imaging of organic materials has provided an insight into the extent of destruction of the original binding medium, as well as

    Full Text Available El presente trabajo da a conocer resultados parciales de la investigación realizada en el marco del proyecto acreditado “Estudio de las Culturas Organizacionales como determinantes de las personas que trabajan en ellas”, cuyo objetivo general es corroborar las características de cada tipo cultural descriptas en la teoría.Los datos que se exponen son el resultado de varios proyectos de investigación desarrollados utilizando la misma metodología. Se ha obtenido gran cantidad de información para analizar variables asociadas al análisis de la cultura organizacional y así, clasificar cada caso en un tipo cultural. Luego, a partir de la base de datos obtenida se han comparado los datos con las características que describe la teoría, a fin de verificarlos o ponerlos en discusión.La conclusión más importante es que la cultura incide en múltiples aspectos de las conductas de las personas y muchos fenómenos, entre ellos los estudiados en este trabajo, así lo demuestran. Es fundamental estudiar este aspecto de las organizaciones en profundidad y no sólo clasificarlas en uno u otro tipo cultural, ya que existen relaciones entre variables que brindan mayor información que resulta relevante para comprender el comportamiento de las personas.

    Full Text Available La Anorexia Nervosa es un trastorno de alimentación que se define (etimológicamente como una "pérdida nerviosa del apetito". Se caracteriza por la actitud consciente, voluntaria y rotunda de los sujetos  de tener un exceso de peso que intentan modificar por vía de la inanición. A partir del estudio de casos, se propone la distinción entre una Anorexia Nervosa Estructural -aquella en la que predomina el conflicto intrapsíquico primario y arcaico, y que manifiesta una conducta aislada y retraída- y una Anorexia Nervosa Reactiva, aquella en la que predomina un conflicto intrafamiliar algo más posterior y, por lo tanto, una personalidad más abierta y compatible con el medio. Anorexia Nervosa is an Eating Disorder defined (etimoligacally as a "nervouse loss of apetite". It is characterized by a conscious, voluntary and categoric attitude of the sick patient to refrain from eating. He/she has a firm conviction of having excess weight which they try to modify by starvation. Through a case study, a distinction between two types of Anorexia Nervosa is proposed: a Structural Anorexia Nervosa -in which an intrapsyhic, primary, arcaic conflic prevails, leading to an isolated, withdrawal conduct- and a Reactive Anorexia Nervosa, in which a later intrafamilial conflict prevails leading, therefore, to a more open personality, compatible with the enviroment.

    1975-12-01

    Full Text Available Diez pacientes afectados por diversas patologías que requerían tratamiento crónico con Vincristina, fueron sometidos a estudios electrofisiológicos en los que se valoró: el número de unidades motoras (UM funcionantes en los músculos de la eminencia tenar, los valores de los incrementos medios de UM, velocidad de conducción motora y su latencia residual en el nervio mediano, la velocidad de conducción sensitiva del mismo nervio y el estado de la transmisión neuromuscular. Los valores obtenidos fueron comparados con grupos controles. Los resultados mostraron disminución del número de UM; las UM remanentes presentaron amplitud reducida junto a otras cuyo tamaño no superaba el del grupo control, hecho que sugiere la incapacidad de lograr una reinervación adecuada. Las velocidades de conducción motora y sensitiva mostraron valores diminuídos, con mayor compromiso en los segmentos distales. Junto a estos datos se halló respuesta miasteniforme al estímulo repetitivo. Todos estos resultados permiten postular la existencia de un compromiso de la unidad motora, abarcando todos sus segmentos, en pacientes intoxicados con Vincristina.

  4. Government science in postwar America: Henry A. Wallace, Edward U. Condon, and the transformation of the National Bureau of Standards, 1945-1951.

    Lassman, Thomas C

    2005-03-01

    In the fall of 1945, Secretary of Commerce Henry Wallace handpicked Edward Condon, a respected theoretical physicist, to become director of the National Bureau of Standards. Already regarded by many academic and industrial scientists as a second-rate research institution, the Bureau had deteriorated further during the Great Depression. An ardent New Dealer who favored government action to prevent anticompetitive behavior in the marketplace, Wallace claimed that giant corporations leveraged their extensive patent holdings and research capabilities to manipulate markets and restrict competition at the expense of smaller firms without similar resources. Through a revitalized Bureau of Standards, Wallace intended to mitigate monopolistic behavior among large companies by transforming the Department of Commerce into an effective clearinghouse for scientific research that would stimulate technological innovation in small businesses. The Bureau's postwar expansion, however, foundered on congressional efforts to dismantle the legacies of the New Deal, Condon's lack of commitment to the technical requirements of the small business community, and the intense competition for resources within an institutionally pluralist federal research establishment dominated by the exigencies of the Cold War. Without sufficient financial support from congressional appropriations committees, Condon turned to the military to fund new research programs at the Bureau of Standards. These programs, however, owed their institutional growth to the demands of the national security state, not to the fading influence of Henry Wallace's New Deal liberalism.

  5. On the history of cultural psychiatry: Georges Devereux, Henri Ellenberger, and the psychological treatment of Native Americans in the 1950s.

    Delille, Emmanuel

    2016-06-01

    Henri Ellenberger (1905-1993) wrote the first French-language synthesis of transcultural psychiatry ("Ethno-psychiatrie") for the French Encyclopédie Médico-Chirurgicale in 1965. His work casts new light on the early development of transcultural psychiatry in relation to scientific communities and networks, particularly on the role of Georges Devereux (1908-1985). The Ellenberger archives offer the possibility of comparing published texts with archival ones to create a more nuanced account of the history of transcultural psychiatry, and notably of the psychological treatment of Native Americans. This paper examines some key moments in the intellectual trajectories of Devereux and Ellenberger, including Devereux's dispute with Ackerknecht, the careers of Devereux and Ellenberger as therapists at the Menninger Foundation (Topeka, Kansas) in the 1950s, and their respective positions in the research network developed by McGill University (Montreal, Quebec) with the newsletter Transcultural Research in Mental Health Problems Finally, I consider their ties to other important figures in this field as it transitioned from colonial medicine to academic medicine, including Roger Bastide (France), Henri Collomb and the Ortigues (France and Africa), as well as Eric Wittkower and Brian Murphy (Canada) and Alexander Leighton (United States and Canada). © The Author(s) 2016.

  10. Las javieradas como caso de estudio

    Mª Cruz Porcal Gonzalo

    2006-01-01

    Full Text Available A pesar de su todavía modesta participación en la economía y en el empleo regional, el turismo en Navarra ha mostrado durante los últimos años un significativo dinamismo tal y como, por ejemplo, lo testimonia el incremento del número de visitantes y de las empresas turísticas. Favorecido por una serie de circunstancias de índole variada, este desarrollo turístico se sustenta en una gran diversidad geográfica y cultural patente en los paisajes, el arte, las fiestas, la gastronomía, etc. Pero Navarra es, a su vez, una región que secularmente ha otorgado un gran peso a la tradición y a las creencias religiosas. En este contexto, algunas de las numerosas acciones emprendidas por la administración regional para dinamizar el sector turístico se han encaminado a revalorizar dos importantes legados culturales: el castillo de Javier y el Camino de Santiago. Se aprecia que ambos se hallan estrechamente relacionados con el turismo cultural, el turismo religioso y las peregrinaciones, unos fenómenos que hunden sus raíces en tiempos pasados pero que continúan teniendo en la actualidad una indudable relevancia a escala mundial. La intención primordial del presente trabajo es analizar el turismo de peregrinaciones en Navarra, más concretamente, el que tiene como destino del viaje la cuna de San Francisco Javier. Con dicho afán, se realiza una reflexión conceptual previa y un breve repaso de las fiestas y tradiciones religiosas que forman parte del patrimonio cultural intangible de Navarra, haciendo particular hincapié en las romerías y en el Camino de Santiago. Al hilo de ello, se afronta, a continuación, el estudio de la peregrinación más singular y populosa de Navarra: la Javierada. Su origen, sus principales rasgos, el perfil y las motivaciones de los peregrinos, los caracteres e hitos más importantes del recorrido, las peculiaridades del destino —entendido como lugar sagrado y espacio turístico— constituyen las principales

  11. A contribuição de Henri Lefebvre para reflexão do espaço urbano da Amazônia

It deals with a concrete attempt in returning to the Marx dialectic, but without the dogmatism the characteristic oppressions concerning other materialist interpretations. However, the present time of the actor reflection inherent to the Amazon urban space and in assignment with its socio-spatial presented in Belém day-to-day allows the exercise of the validity acknowledgment of such thought along with apprehension of the Amazon city complexity.O espaço considerado como historicamente produzido pelo homem à medida que organiza política e economicamente a sua sociedade, esta é a afirmação que distingue o conjunto das obras de Henri Lefebvre.

  18. Bayard Holmes (1852-1924) and Henry Cotton (1869-1933): Surgeon-psychiatrists and their tragic quest to cure schizophrenia.

    Davidson, Jonathan

    2016-11-01

    Early 20th-century medicine was dominated by the infectious theory of disease. Some leading physicians believed that infection or the accumulation of toxic substances from bacterial stasis caused a wide range of diseases, including schizophrenia. In the case of schizophrenia, one theory held that intestinal stasis lead to the bacterial production of toxins that affected brain function, resulting in psychotic illness. This theory predicted that clearing the stasis by drainage or by removal of the offending organ would be curative. Bayard Holmes and Henry Cotton, surgeon-psychiatrists, achieved notoriety for their efforts to cure schizophrenia surgically. Their endeavours were not only a failure but resulted in tragedy to their families and to a wider population. Treatment of their own sons also represented a violation of the ethics of their time. This account describes the life and career of Holmes and Cotton and reappraises their work in the light of recent developments. © IMechE 2014.

  19. Impact of economic fluctuations on suicide mortality in Canada (1926-2008): Testing the Durkheim, Ginsberg, and Henry and Short theories.

    Thibodeau, Lise; Lachaud, James

    2016-01-01

    Three theories have been proposed to explain the relationship between suicide and economic fluctuations, including the Durkheim (nonlinear), Ginsberg (procyclical), and Henry and Short (countercyclical) theories. This study tested the effect of economic fluctuations, measured by unemployment rate, on suicide rates in Canada from 1926 to 2008. Autoregressive integrated moving average time-series models were used. The results showed a significant relationship between suicide and economic fluctuation; this association was positive during the contraction period (1926-1950) and negative in the period of economic expansion (1951-1973). Males and females showed differential effects in the period of moderate unemployment (1974-2008). In addition, the suicide rate of mid-adults (45-64) was most impacted by economic fluctuations. Our study tends to support Durkheim's theory and suggests the need for public health responses in times of economic contraction and expansion.

Leur analyse comparative permet de suivre pas à pas l’évolution de la création, du projet initial à la réalisation de l’ensemble vitré.The realisation of a stained-glass window requires the association of several skills including those of the designer (the ‘cartonnier’ or cartoon painter and the painter on glass. The restoration of the stained-glass windows of the chapels and ambulatory of the Sainte-Marguerite church at Le Vesinet (Yvelines allowed for a study of the close collaboration between the painter Maurice Denis and the glass painter Henri Carot. Many documents were brought to light during the restoration project and have been studied: projects, drawings, sketches and two series of full-scale design cartoons. The comparative analysis of these documents allows the creation of the stained-glass to be followed step by step, from the initial project to the final realisation.

The clinical history about of animal included: signs of severe abdominal distension, anorexia, poliaquiuria, straguria and prolonged urination posture, urine dribbling and blood-tinged urine. Necropsy revealed ascitis and a hemorrhagic fibrine membrane floating in approximately 8 litres of urine caused by a rupture of the urinary bladder in consequence of a total blockage of urethral lumen by multiple small stones localized in the sigmoid flexure of the animal. Obstructive urolithiasis is a common problem in the fed-flocks affecting between 20 % and 30 % of the animals. A diet with adequate mineral balance could reduce the health risk of formation of urinary stones. Un ovino macho de 5 meses de edad fue presentado para su estudio patológico. La historia clínica del animal incluía: postración, dificultad para incorporarse, distensión abdominal severa, pérdida de apetito, estranguria, poliaquiuria y hematuria. A la necropsia se observó la presencia de 8 litros aproximadamente de orina en cavidad abdominal y una membrana fibrino-hemorrágica flotante adherida a la vejiga a nivel de la lesión de ruptura, por una sobre distensión provocada por la presencia obstructiva total de cálculos urinarios localizados en la luz de la uretra a nivel de la flexura sigmoidea del animal. La urolitiasis obstructiva es una patología que se presenta en el 20 % - 30 % de los animales en engorda. Un adecuado balance mineral de la dieta rica en concentrados puede reducir el riesgo de la formación de urolitos.

    Full Text Available Con base en la revisión de algunos estudios recientes que se han llevado a cabo en diver- sas comunidades rurales de las nuevas regiones migratorias, en este artículo se revisan, de manera crítica, dos interpretaciones de los estudios sobre la familia rural: la economía campesina como unidad de producción-consumo y el ciclo de desarrollo de la unidad doméstica. En las condiciones actuales la migración, interna e internacional, desem- peña un papel decisivo en las comunidades rurales. Muchos estudios han constatado la voluntad de las mujeres de salir de los grupos domésticos y sumarse a los flujos migra- torios por motivos particulares, por situaciones y demandas específicas de ellas; su salida ha contribuido al resquebrajamiento de los sistemas tradicionales de organización y re- producción de la familia campesina. Las feministas, y más tarde los estudios con la perspectiva de género, criticaron la visión de que las familias rurales constituían unidades de producción-consumo donde las decisiones correspondían a un modelo de estrategias familiares de sobrevivencia y reproducción (Hondagneu-Sotelo, 2007; Wolf, 1990. Ese modelo privilegiaba la homo- geneidad, la colectividad, la solidaridad y el consenso, es decir, suponía que en los hogares no había conflictos ni tensiones a la hora de tomar decisiones que a todos com- prometían (Ariza, 2007. La familia era una “unidad económica moral” que se susten- taba en los principios de “reciprocidad, consenso y altruismo” (Grasmuck y Pessar, 1991. Los estudios desde el enfoque de género señalaron que en las familias había relacio- nes de poder basadas en una distribución jerárquica y desigual de los derechos, recursos y autoridad que afectaban especialmente a las mujeres (Ariza, 2007; González Montes, 2002; Hondagneu-Sotelo, 2007; Wolf, 1990.

  14. 圣徒与国王之间——《亨利六世》的宗教伦理%Between Saint and King: The Religious Ethics in Henry VI

    邹广胜; 穆宝清

    2012-01-01

    上、中、下三部的《亨利六世》是莎士比亚戏剧中最长的,也是最优秀的剧作之一,然而这部剧作却常常被莎学家们忽略,特别是亨利六世这位被描写成以宗教原则来处理政事的国王也同样受到误解。但《亨利六世》对历史深邃的理解、对民族强烈的热爱、对人性深刻的洞察,特别是以宗教伦理原则对王位的反思更是让今日的读者产生无限的沉思与遐想。%Henry VI, a history play by William Shakespeare which firmly establishes his reputa- tion as a playwright, is often neglected by modern critics. Henry VI as the king who governs the realm of England not by law but by religious ethics is also misinterpreted by some Shakespeareans. However, with the profound understanding of history, the devotion to the coun- try, the insight into humanity, and especially the untimely King Henry VI' s reflections on his reign, this history play provides present-day readers with unlimited contemplation and imagina- tion.

    Nathalie Padilla

    2006-01-01

    Full Text Available During the 18th century, Shakespeare’s Macbeth was a source of inspiration for many painters who tried to underscore the pictorial quality of the play, especially that of Act 1, scene 3. The paper compares the interpretations offered by Henry Fuseli and Francesco Zuccarelli who were both foreign artists belonging to the Royal Academy of London. Their paintings after Act 1, scene 3, of Macbeth offer a visual representation articulated around contrast and convergence: if Fuseli remains faithful to the pivotal emotional intent, seen as the “ergon” here, Zuccarelli almost ignores it, finding a greater interest in the landscape of the scene that fills most of his pictorial space. However, the two works fuse together within the etymology of the term “ergon”, that equates with “work” or “action”. They illustrate the idea of active witchcraft through natural phenomena controlled by the three witches.

  17. “Too Long in Foreign Parts”?: An Asian Reception to Cosmopolitanism in Henry James’s The American and The Portrait of a Lady

    Patricia Haseltine

    2012-04-01

    Full Text Available The works of Henry James with their attention to cosmopolitanism in the late nineteenth and early twentieth centuries provide valuable insight into contemporary expectations of cultural hybridity and globalism. This paper assesses the ways students studying English as a foreign language in Taiwan read the cultural exchanges between Americans and Europeans in James’s "The American" (1877 and "The Portrait of a Lady" (1881. It places the main attention upon how students evaluate James’s characters based upon their own attitudes toward cosmopolitanism, work and leisure, and women’s independence. Informed by the travel theory of Mary Louise Pratt (2008 and Homi Bhabha’s (1994 concept of the third space, it studies the negotiation and subversion of meaning in postcolonial and reverse-colonial contexts. The analysis of student responses reveals that in this culturally hybrid reading site, the limited consciousness technique of James generates judgments of characters’ potentialities based upon the students’ own values. Reconciling the cultural oppositions in the self to become a citizen of the world remains an ideal they do not see fully realized in James’s highly conflicted characters, and, as their own partial views attest, not realizable in their own lives.

  18. Development of a Henry's constant correlation and solubility measurements of n-pentane, i-pentane, cyclopentane, n-hexane, and toluene in water

    Chapoy, Antonin; Haghighi, Hooman; Tohidi, Bahman

    2008-01-01

    In this communication, we report new experimental data on n-pentane, i-pentane, cyclopentane, n-hexane, and toluene solubility in water at low temperature (below 298.15 K) and atmospheric pressure conditions. The new experimental data together with those reported in the literature have been used in developing a new equation for Henry's constants of normal alkanes (methane to decane), BETEX compounds, and acid gases in aqueous phase over a wide range of temperature (typically from 273.15 K to 373.15 K). The new equation is based on a thermodynamic model, which uses the Peng-Robinson equation of state combined with the classical quadratic mixing rules for modelling non-aqueous phases, while the NRTL model is used to calculate the water activity. The predictions of the developed thermodynamic model are compared to the experimental data and the results of a thermodynamic approach, which uses the Valderrama modification of the Patel-Teja equation of state and non-density dependent mixing rules for modelling all fluid phases. Good agreement is observed between the experimental data and the model predictions

  19. The Paradox of a Gesture, Enlarged by the Distension of Time: Merleau-Ponty and Lacan on a Slow-Motion Picture of Henri Matisse Painting

    Astrid Deuber-Mankowsky

    2017-06-01

    Full Text Available In his lecture series The Four Fundamental Concepts of Psychoanalysis (1964, Lacan refers to a “delightful example” that Merleau-Ponty gives in his Book Signes (1960. Lacan describes it as a “strange slow-motion film in which one sees Matisse painting.” This is a scene from the documentary entitled A Great French Painter, Henri Matisse, by director François Campaux, a 16mm black and white film shot in 1946. Merleau-Ponty points, as Lacan puts it, to “the paradox of that gesture which, enlarged by the distension of time, enables us to imagine the most perfect deliberation on each of these strokes.” In fact, Merleau-Ponty underscores that this is an illusion, due only to the technique of the slow motion picture. In this paper I will present the different ways in which Lacan and Merleau-Ponty refer to the slow motion picture of Matisse painting. I will do so in order to consider, comparatively, the ways in which Merleau-Ponty and Lacan define the gesture in reference to film technologies and to the process of subjectification. Both of them refer to the gesture in order to find a new balance in the relationship between subject, rationality and media technology. And it is exactly at this site where the question of an ethics of gesture appears.

  20. Reading the Unknown/Speaking the Unspoken—An Analogy between Henry James’ What Maisie Knew and the Oscar Wilde Trial: Did James Really Know What Maisie Knew?

    Dr. Michael R. Catanzaro

    2013-06-01

    Full Text Available The explicit and implicit language in Henry James’ novel, What Maisie Knew, reveals that the act of censoring was not exclusive to writers, since moral attitudes affected every aspect of society; consequently, people developed a means of communication via looks, gestures, and intonation that gave significant meaning to ordinary words and phrases, if one was part of the group “in the know.” This coded means of communication resulted from the anxiety of being accused of immoral activity by the political and religious regulating mechanisms, especially in a volatile society where many feared the outcome of a nation that was changing so rapidly. It was a means of protection. When writers could not provide graphically specific language and details, they would manipulate words to create a desired effect that relied on the readers to draw on their personal knowledge and experiences to supply meaning to the text; therefore, the interpretation was affected by the relationship between the reader and the subject matter.

    2013-06-01

    Full Text Available The explicit and implicit language in Henry James’ novel, What Maisie Knew, reveals that the act of censoring was not exclusive to writers, since moral attitudes affected every aspect of society; consequently, people developed a means of communication via looks, gestures, and intonation that gave significant meaning to ordinary words and phrases, if one was part of the group “in the know.” This coded means of communication resulted from the anxiety of being accused of immoral activity by the political and religious regulating mechanisms, especially in a volatile society where many feared the outcome of a nation that was changing so rapidly. It was a means of protection. When writers could not provide graphically specific language and details, they would manipulate words to create a desired effect that relied on the readers to draw on their personal knowledge and experiences to supply meaning to the text; therefore, the interpretation was affected by the relationship between the reader and the subject matter.

  2. Primater emellan. En läsning av Henry Drummonds berättelse ”Apan som ingen kunde döda”

    Full Text Available ”The anthropocentric primate. A species discursive reading of the story ‘The monkey that would not kill.’” In children's literature nonhuman primates are often represented either as ferocious beasts or as curios and charmful vicarious children. In this article I demonstrate how these different constructions interestingly coexist in the popular story ”The monkey that would not kill”, written by the Scottish evangelist and professor of the natural sciences Henry Drummond in 1891. My study anchors the figuration of the monstrous ape historically in a Christian discourse and the figuration of the childlike ape in a zoological discourse, and link them to the literary genres of horror and comedy, respectively. Both of the figurations are anthropocentric in their reductive ways of representing the ape as strange enemy or subordinate ”friend”: they confirm the hierarchic dualism between man and ape. My reading also points out the excessive passion that characterizes the meeting between the species in the story, as a kind of leakage from the dualism. In light of Giorgio Agamben's concept of the ”anthropological machine”, I conclude the article reflecting on the human shepherd's energetic attempts to kill the animal not only as an act of domination, but also as bearing witness to the obsession with ”experimenting” with other primates, in order to consolidate a human species identity.

  3. Más allá de la gnosis griega. El estoicismo y Michel Henry a propósito de la afectividad, la vida y la comunidad

    Hernán Gabriel Inverso

    2017-04-01

    Full Text Available En el contexto de su crítica a la fenomenomenología husserliana Michel Henry apela a la caracterización de los errores de la perspectiva hetero-afectiva remitiéndose a sus orígenes en la tradición sintetizados en los parámetros de la “gnosis griega” y su compromiso con la racionalidad entendida como comprensión de “objetos puestos a distancia”. La revisión de los alcances de esta categoría revela, sin embargo, que existen tratamientos en el pensamiento griego que apelan a la auto-afección y la inmanencia para dar cuenta de elementos que exceden la dimensión ek-stática. En este trabajo se revisa el planteo henryano para mostrar sus puntos de contacto con el estoicismo, especialmente a partir de la teoría de Hierocles a propósito de la oikeîosis. Este recorrido permitirá sugerir que entre ambos planteos existe una compatibilidad estructural que hace posible apelar a claves de interpretación similares para dar cuenta de la convivencia de mecanismos de explicación que apelan a lo auto-afectivo y lo hétero-afectivo en un conjunto coherente.

  4. Use of experimentally determined Henry's Law and salting-out constants for ethanol in seawater for determination of the saturation state of ethanol in coastal waters.

    Willey, Joan D; Powell, Jacqueline P; Avery, G Brooks; Kieber, Robert J; Mead, Ralph N

    2017-09-01

    The Henry's law constant for ethanol in seawater was experimentally determined to be 221 ± 4 M/atm at 22 °C compared with 247 ± 6 M/atm in pure water. The salting out coefficient for ethanol was 0.13 M -1 . In seawater ln(K H ) = -(12.8 ± 0.7) + (5310 ± 197)/T where K H is in M atm -1 and temperature is in K. This plus the salting out coefficient allow calculation of K H for any estuarine or sea water between 1 and 35 °C. High concentrations of dissolved organic carbon do not affect K H values in fresh or seawater. Nearshore surface waters were usually undersaturated with respect to gas phase ethanol except when air concentrations decreased, whereas surface seawater 40 km from shore was supersaturated. The percent saturation in surface waters is driven primarily by changes in air concentrations because these change quickly (hours) and more extensively than surface water. This study allows calculation of ethanol saturation states from air and surface water concentrations which is a necessary step to define the role of surface oceans in the global biogeochemical cycling of ethanol both now and in the future as use of ethanol biofuel continues to grow.

  10. Suspended-sediment budget, flow distribution, and lake circulation for the Fox Chain of Lakes in Lake and McHenry Counties, Illinois, 1997-99

    Schrader, David L.; Holmes, Robert R.

    2000-01-01

    The Fox Chain of Lakes is a glacial lake system in McHenry and Lake Counties in northern Illinois and southern Wisconsin. Sedimentation and nutrient overloading have occurred in the lake system since the first dam was built (1907) in McHenry to raise water levels in the lake system. Using data collected from December 1, 1997, to June 1, 1999, suspended-sediment budgets were constructed for the most upstream lake in the system, Grass Lake, and for the lakes downstream from Grass Lake. A total of 64,900 tons of suspended sediment entered Grass Lake during the study, whereas a total of 70,600 tons of suspended sediment exited the lake, indicating a net scour of 5,700 tons of sediment. A total of 44,100 tons of suspended sediment was measured exiting the Fox Chain of Lakes at Johnsburg, whereas 85,600 tons entered the system downstream from Grass Lake. These suspended-sediment loads indicate a net deposition of 41,500 tons downstream from Grass Lake, which represents a trapping efficiency of 48.5 percent. A large amount of recreational boating takes place on the Fox Chain of Lakes during summer months, and suspended-sediment load was observed to rise from 110 tons per day to 339 tons per day during the 1999 Memorial Day weekend (May 26 ?31, 1999). Presumably, this rise was the result of the boating traffic because no other hydrologic event is known to have occurred that might have caused the rise. This study covers a relatively short period and may not represent the long-term processes of the Fox Chain of Lakes system, although the sediment transport was probably higher than an average year. The bed sediments found on the bottom of the lakes are composed of mainly fine particles in the silt-clay range. The Grass Lake sediments were characterized as black peat with an organic content of between 9 and 18 percent, and the median particle size ranged from 0.000811 to 0.0013976 inches. Other bed material samples were collected at streamflow-gaging stations on the

  11. On the Echoes of Henry James’s The Reverberator: Reflections on Teaching Argumentative Research Papers in Undergraduate Classes on Literature

    Nevena Stojanovic

    2017-09-01

    Full Text Available In this essay, I reflect on the teaching experiment that I did several years ago in my class on transatlantic short stories and novels of the nineteenth century. As instructors of literature in a university setting, we often face the question of how to teach undergraduate students what a researched argument is and how to help them come up with effective thesis statements. The number of students, their different educational backgrounds, skills, and motivations can all be a challenge for instructors who need to make sure that everyone enrolled in the class understands the complex processes of research and argumentative writing before starting the draft. Our major concern, however, is how to keep students fully engaged in the processes of exploration, research, and drafting. Here I share my experience of teaching these processes in two 75-minute sessions. I include the methods of teaching and the homework and in-class prompts assigned to the class. I used the model similar to the one that Ashley M. Walter proposed in her thesis, which consists of discussion, providing students with a frame/stance, and transmediation. To this model, I added a mini-session on the in-class exploration of our library’s databases and brainstorming thesis statements. I chose Henry James’s brief and witty novel The Reverberator (1888 for the purposes of this process, mainly because this text has been neglected in the criticism on James’s late work, and I wanted to see what kinds of arguments my students would come up with to recover it.

  12. Comparison of machine learning techniques to predict all-cause mortality using fitness data: the Henry ford exercIse testing (FIT) project.

    Prior studies have demonstrated that cardiorespiratory fitness (CRF) is a strong marker of cardiovascular health. Machine learning (ML) can enhance the prediction of outcomes through classification techniques that classify the data into predetermined categories. The aim of this study is to present an evaluation and comparison of how machine learning techniques can be applied on medical records of cardiorespiratory fitness and how the various techniques differ in terms of capabilities of predicting medical outcomes (e.g. mortality). We use data of 34,212 patients free of known coronary artery disease or heart failure who underwent clinician-referred exercise treadmill stress testing at Henry Ford Health Systems Between 1991 and 2009 and had a complete 10-year follow-up. Seven machine learning classification techniques were evaluated: Decision Tree (DT), Support Vector Machine (SVM), Artificial Neural Networks (ANN), Naïve Bayesian Classifier (BC), Bayesian Network (BN), K-Nearest Neighbor (KNN) and Random Forest (RF). In order to handle the imbalanced dataset used, the Synthetic Minority Over-Sampling Technique (SMOTE) is used. Two set of experiments have been conducted with and without the SMOTE sampling technique. On average over different evaluation metrics, SVM Classifier has shown the lowest performance while other models like BN, BC and DT performed better. The RF classifier has shown the best performance (AUC = 0.97) among all models trained using the SMOTE sampling. The results show that various ML techniques can significantly vary in terms of its performance for the different evaluation metrics. It is also not necessarily that the more complex the ML model, the more prediction accuracy can be achieved. The prediction performance of all models trained with SMOTE is much better than the performance of models trained without SMOTE. The study shows the potential of machine learning methods for predicting all-cause mortality using cardiorespiratory fitness

  13. Experimental determination of Henry's law constants of difluoromethane (HFC-32 and the salting-out effects in aqueous salt solutions relevant to seawater

    Full Text Available Gas-to-water equilibrium coefficients, KeqS (in M atm−1, of difluoromethane (CH2F2, a hydrofluorocarbon refrigerant (HFC-32, in aqueous salt solutions relevant to seawater were determined over a temperature (T range from 276 to 313 K and a salinity (S range up to 51 ‰ by means of an inert-gas stripping method. From the van't Hoff equation, the KeqS value in water, which corresponds to the Henry's law constant (KH, at 298 K was determined to be 0.065 M atm−1. The salinity dependence of KeqS (the salting-out effect, ln(KH∕KeqS, did not obey the Sechenov equation but was proportional to S0. 5. Overall, the KeqS(T value was expressed by ln(KeqS(T  =  −49.71 + (77.70 − 0.134  ×  S0. 5  ×  (100∕T + 19.14  ×  ln(T∕100. By using this equation in a lower-tropospheric semi-hemisphere (30–90 °S of the Advanced Global Atmospheric Gases Experiment (AGAGE 12-box model, we estimated that 1 to 4 % of the atmospheric burden of CH2F2 resided in the ocean mixed layer and that this percentage was at least 4 % in the winter; dissolution of CH2F2 in the ocean may partially influence estimates of CH2F2 emissions from long-term observational data of atmospheric CH2F2 concentrations.

    Poplars are ideal for phytoremediation because of their high water usage, fast growth, and deep root systems. We measured in 2002 and 2003 the sapflow of hybrid poplars (Populus nigra L.xP. maximowiczii A. Henry 'NM6') planted in 1999 for phytoremediation of a landfill in Rhinelander, WI, USA (45.6{sup o}N, 89.4{sup o}W). Mean sap velocity per tree was 100+/-10 and 120+/-10{mu}ms{sup -1} for 2002 and 2003, respectively. Mean sapflow per tree was 1.4000+/-0.1698 and 5.6760+/-0.2997kgh{sup -1} for 2002 and 2003, respectively.

  15. Estudios pioneros en torno al origen del lenguaje natural

    Martínez Contreras, Jorge

    2011-02-01

    Full Text Available It has being an ancient desire to ask apes what their natural lives are. De la Mettrie was the first to propose, in the 18th C., that the sign language of deaf adults could be used with them since they do not speak. We enhance here some of the pioneering projects of the two strategies for this endeavor: the use of ASL and the utilization of lexigrams and computers. Besides the ancient communicative quest with them, the evolutionist’s perspective has seen in these studies a way to find out how the natural language (NL emerged in hominids. If it is clear that apes do no possess totally the NL, the linguistic turn in primatology has left way, as in philosophy, to more complex field and laboratory cognitive studies of less anthropocentric nature.

    Tratar de hablar con los simios y preguntarles cosas sobre su vida natural es un viejo deseo. De la Mettrie propone, en el s. XVIII, que se les enseñe el lenguaje de los sordos en vista de que no pueden hablar. Resaltamos aquí algunos estudios pioneros en relación con las dos estrategias llevadas a cabo para tratar de hablar con los simios: el uso del lenguaje americano de sordos (ASL y el de los lexigramas y computadoras. Además del viejo interés interrogativo humano hacia ellos, la perspectiva evolucionista ha visto en estos estudios un medio de investigar cómo surgió el lenguaje natural (LN en homínidos. Si queda claro que los simios no poseen totalmente el LN, el giro lingüistico en primatología ha cedido, como en filosofía, el paso a estudios cognitivos más complejos, de campo y de laboratorio, de orientación menos antropomórfica.

    Full Text Available El desarrollo acelerado de la Industria Biofarmacéutica, y en particular de la producción de biológicos, ha permitido el incremento de la investigación clínica, teniendo en consideración la novedad de las sustancias que se desarrollan. El éxito de un producto solo se logra a través de la realización de los estudios clínicos controlados, lo cual significa que este ha sido validado a través de un sistema de gestión de calidad, principal determinante para que la molécula en estudio, pueda ser autorizada y comercializada posterior a la demostración de su seguridad y eficacia. Previo a la presentación de una solicitud para un nuevo producto ante las autoridades regulatorias, es necesario pasar por la etapa de investigación preclínica.

  19. Viviendo en Flatland. El estudio comparado del crimen violento

    Luis David Ramírez de Garay

    2013-05-01

    Full Text Available Esta nota de investigación indaga sobre el notorio rezago que la criminología y la sociología del crimen tienen en la aplicación de la metodología comparada. A diferencia de la ciencia política y algunas áreas de la investigación sociológica, la metodología comparada no ocupa un lugar preponderante en la investigación empírica del crimen. Sin embargo, existen algunos valiosos ejemplos sobre las ventajas del estudio comparado del crimen y del crimen violento. Por ello, incluyo una breve revisión del estado actual de dichos estudios y de sus inherentes limitaciones teóricas y metodológicas. Finalmente, concluyo la nota presentando mi propuesta para incorporar la metodología comparada en la agenda de investigación sobre las bases sociales del crimen y del crimen violento

  2. Litiasis renal: estudio y manejo endocrinológico

    V. Gilberto González, Dr.

    2013-09-01

    Full Text Available La litiasis renal es causa de importante morbilidad y costo económico, afectando hasta el 15% de la población. Además, la litiasis renal puede ser expresión también de enfermedades extrarrenales, entre las cuales destaca riesgo aumentado de osteoporosis. Estudios nacionales muestran que las causas de litiasis renal en Chile son similares a las comunicadas internacionalmente, destacando la hipercalciuria idiopática como el principal factor de riesgo. A pesar de los avances en técnicas urológicas de remoción de cálculo, éstas no modifican la historia natural de la litiasis renal. Así, en los pacientes sin tratamiento médico, la recurrencia es la regla más que la excepción. En esta revisión se actualiza el estudio y manejo endocrinológico de la litiasis renal, para el cual la evidencia muestra que éste es eficaz y seguro en la prevención de recurrencia de litiasis renal y control de enfermedades asociadas, complementando así el manejo urológico de esta importante enfermedad.

  9. Estudio del impacto ambiental de medicamentos de control especial en Bogotá, Colombia. Caso de estudio: Lorazepam

    Ibeth Eileen López

    2016-01-01

    Full Text Available El aumento de la población y la cobertura de los sistemas de salud, así como el crecimiento del mercado farmacéutico, ha dado lugar a la presencia de una nueva generación de residuos peligrosos, que no habían sido considerados como tal. En Colombia, no se han realizado suficientes estudios relacionados con el impacto ambiental ocasionado por la disposición final de medicamentos, porque no existen cifras disponibles acerca de la cantidad depositada diariamente en rellenos sanitarios, destruida en plantas gestoras de residuos peligrosos o encontrada en plantas de tratamiento de aguas residuales. Se encontró en esta investigación que sólo en Bogotá, se destruyen en promedio anualmente 9.310.123 unidades farmacéuticas de productos de control especial, sin considerar las unidades desechadas a nivel doméstico. Para estudiar el impacto ambiental, se seleccionó el principio activo lorazepam, la información sobre la cantidad del medicamento consumida y destruida en plantas gestoras de residuos peligrosos en la ciudad de Bogotá, durante los años 2012 y 2013, fue aportada por el Fondo Nacional de Estupefacientes. Los datos fueron evaluados utilizando la matriz de Leopold, software especializado y ensayos de laboratorio complementarios. Este estudio pretende sensibilizar a fabricantes, prescriptores y pacientes sobre la responsabilidad ambiental en el uso de medicamentos de control especial.

  10. Estudio de Recursos Humanos del Sector Salud en Colombia.

    Full Text Available

    Antecedentes


    Siendo el recurso humano el en cargado de movilizar los demás recursos e impulsarlos de tal manera que conlleve a una dinámica de producción masiva de bienes o servicios, su estudio para llegar a una identificación real, categorización, clasificación; es necesario en cualquier área del conocimiento.

    Frente al nuevo esquema de prestación de servicios propuestos, los profesionales de la salud han perdido aquella posición digna, de respeto y liderazgo dentro del sistema y dentro de su entorno social, lo cual ha llevado a muchos de ellos a desertar de sus oficios originales, con lo cual se llega a la falla en la instauración del Sistema.

    Así mismo la Ley 100 de 1993 que debió ser vista como una nueva oportunidad de negocios dentro de las diferentes profesiones de la salud, se transformó en una seria amenaza para el ejercicio independiente de cada profesión.

    No es apropiado ni satisfactorio dejar un proceso decisorio de tal magnitud en manos de otros sectores que únicamente verán y obtendrán estadísticas del acceso de la población colombiana a estudios superiores y los renglones en los cuales quieren desempeñarse y se desempeñarán en un futuro. El sector de la salud debe tomar un claro papel protagónico frente a la promulgación de políticas de formación y utilización de su recurso humano.

    La Academia Nacional de Medicina consciente del vacío existente en el sector con respecto al tema, ha querido desde su posición estratégica con respecto a las profesiones del área y las universidades, liderar un proceso que conlleve a la organización de un Estudio del recurso humano del Sector Salud en Colombia, tomando como punto de partida el censo de los trabajadores de la salud en todas las áreas, de tal manera que se identifique su disponibilidad, su capacidad, la ubicación, las facilidades laborales en zonas aisladas y su grado de satisfacción, entre otras

  11. Cardiorespiratory fitness attenuates risk for major adverse cardiac events in hyperlipidemic men and women independent of statin therapy: The Henry Ford ExercIse Testing Project.

    Hung, Rupert K; Al-Mallah, Mouaz H; Qadi, Mohamud A; Shaya, Gabriel E; Blumenthal, Roger S; Nasir, Khurram; Brawner, Clinton A; Keteyian, Steven J; Blaha, Michael J

    2015-08-01

    We sought to evaluate the effect of cardiorespiratory fitness (CRF) in predicting mortality, myocardial infarction (MI), and revascularization in patients with hyperlipidemia after stratification by gender and statin therapy. This retrospective cohort study included 33,204 patients with hyperlipidemia (57 ± 12 years old, 56% men, 25% black) who underwent physician-referred treadmill stress testing at the Henry Ford Health System from 1991 to 2009. Patients were stratified by gender, baseline statin therapy, and estimated metabolic equivalents from stress testing. We computed hazard ratios using Cox regression models after adjusting for demographics, cardiac risk factors, comorbidities, pertinent medications, interaction terms, and indication for stress testing. There were 4,851 deaths, 1,962 MIs, and 2,686 revascularizations over a median follow-up of 10.3 years. In men and women not on statin therapy and men and women on statin therapy, each 1-metabolic equivalent increment in CRF was associated with hazard ratios of 0.86 (95% CI 0.85-0.88), 0.83 (95% CI 0.81-0.85), 0.85 (95% CI 0.83-0.87), and 0.84 (95% CI 0.81-0.87) for mortality; 0.93 (95% CI 0.90-0.96), 0.87 (95% CI 0.83-0.91), 0.89 (95% CI 0.86-0.92), and 0.90 (95% CI 0.86-0.95) for MI; and 0.91 (95% CI 0.88-0.93), 0.87 (95% CI 0.83-0.91), 0.89 (95% CI 0.87-0.92), and 0.90 (95% CI 0.86-0.94) for revascularization, respectively. No significant interactions were observed between CRF and statin therapy (P > .23). Higher CRF attenuated risk for mortality, MI, and revascularization independent of gender and statin therapy in patients with hyperlipidemia. These results reinforce the prognostic value of CRF and support greater promotion of CRF in this patient population. Copyright © 2015 Elsevier Inc. All rights reserved.

  12. The `Henry Problem' of `density-driven' groundwater flow versus Tothian `groundwater flow systems' with variable density: A review of the influential Biscayne aquifer data.

    Weyer, K. U.

    2017-12-01

    Coastal groundwater flow investigations at the Biscayne Bay, south of Miami, Florida, gave rise to the concept of density-driven flow of seawater into coastal aquifers creating a saltwater wedge. Within that wedge, convection-driven return flow of seawater and a dispersion zone were assumed by Cooper et al. (1964) to be the cause of the Biscayne aquifer `sea water wedge'. This conclusion was based on the chloride distribution within the aquifer and on an analytical model concept assuming convection flow within a confined aquifer without taking non-chemical field data into consideration. This concept was later labelled the `Henry Problem', which any numerical variable density flow program must be able to simulate to be considered acceptable. Both, `density-driven flow' and Tothian `groundwater flow systems' (with or without variable density conditions) are driven by gravitation. The difference between the two are the boundary conditions. 'Density-driven flow' occurs under hydrostatic boundary conditions while Tothian `groundwater flow systems' occur under hydrodynamic boundary conditions. Revisiting the Cooper et al. (1964) publication with its record of piezometric field data (heads) showed that the so-called sea water wedge has been caused by discharging deep saline groundwater driven by gravitational flow and not by denser sea water. Density driven flow of seawater into the aquifer was not found reflected in the head measurements for low and high tide conditions which had been taken contemporaneously with the chloride measurements. These head measurements had not been included in the flow interpretation. The very same head measurements indicated a clear dividing line between shallow local fresh groundwater flow and saline deep groundwater flow without the existence of a dispersion zone or a convection cell. The Biscayne situation emphasizes the need for any chemical interpretation of flow pattern to be supported by head data as energy indicators of flow fields

    2008-01-01

    The author discusses the various ways to convince the greatest number of people to strongly reduce their greenhouse gas emissions. He first notes that the main reason for that is the perspective of fossil energy shortage, and comments some assessments of the cost of these energy savings, and ways to assess energy consumption with respect to carbon consumption savings. In order to promote better behaviours, he suggests that the State would define a normative value for fuel consumption by end users which would be independent of actual oil, coal or gas prices, and that any action would be considered as useful if it is less expensive that the use of oil, gas or any other fuel. He gives an overview of the already existing means to reduce emissions: biomass, nuclear energy, and energy savings. He proposes some ideas to convince consumers-users

    Full Text Available Abstract The study of the emotional world of the elderly is a fundamental requisite for guaranteeing the well-being and health of this group. The objective of this research paper was to characterize a group of elderly people according to their motional capabilities. The group consisted of 122 elderly persons: 107 female, 15 male. All attendants participated in a “Círculo de Abuelos” (Circle of Grandparents. The study was descriptive, it sought to gather information about the responses of older adults in situations of emotional content by completing a questionnaire. The results provided a profile of capacities where areas of strength and weakness are clearly distinguished. Selfconfidence and the possibility of fulfilling projects are among the strengths while the weaknesses are found in interpersonal or intrapersonal managing of emotions. These results have led to a better understanding of the emotional world of the elderly and guide future educational activities. Resumen El estudio del mundo emocional de los adultos mayores es un requisito fundamental para garantizar el estado de bienestar y salud de los mismos. El presente artículo de investigación se fijó como objetivo caracterizar a un grupo de ancianos, en función de sus capacidades emocionales. Los participantes fueron 122 ancianos, en concreto 107 mujeres y 15 hombres, que asisten a un “Círculo de Abuelos”. El estudio fue de tipo descriptivo, pues pretendió recoger información acerca de las respuestas de los adultos mayores ante situaciones de contenido emocional que se exploran por medio de un cuestionario elaborado al efecto. Los resultados ofrecen un perfil de capacidades en que la autoconfianza y la posibilidad de elaborar proyectos se erigen como fortalezas, mientras que las debilidades se expresan en las dificultades para el manejo emocional tanto a nivel intra como interpersonal. Estos resultados han permitido lograr una mejor comprensión del mundo emocional del

  12. Hydrogeology and water quality of sand and gravel aquifers in McHenry County, Illinois, 2009-14, and comparison to conditions in 1979

    Gahala, Amy M.

    2017-10-26

    Baseline conditions for the sand and gravel aquifers (groundwater) in McHenry County, Illinois, were assessed using data from a countywide network of 44 monitoring wells collecting continuous water-level data from 2009–14. In 2010, water-quality data were collected from 41 of the monitoring wells, along with five additional monitoring wells available from the U.S. Geological Survey National Water Quality Assessment Program. Periodic water-quality data were collected from 2010–14 from selected monitoring wells. The continuous water-level data were used to identify the natural and anthropogenic factors that influenced the water levels at each well. The water-level responses to natural influences such as precipitation, seasonal and annual variations, barometric pressure, and geology, and to anthropogenic influences such as pumping were used to determine (1) likely hydrogeologic setting (degree of aquifer confinement and interconnections) that, in part, are related to lithostratigraphy; and (2) areas of recharge and discharge related to vertical flow directions. Water-level trends generally were determined from the 6 years of data collection (2009–14) to infer effects of weather variability (drought) on recharge.Precipitation adds an estimated 2.4 inches per year of recharge to the aquifer. Some of this recharge is subsequently discharged to streams and some is discharged to supply wells. A few areas in the eastern half of the county had higher average recharge rates, indicating a need for adequate protection of these recharge areas. Downward vertical flow gradients in upland areas indicate that recharge to the confined aquifer units occurs near upland areas. Upward vertical flow gradients in lowland areas indicate discharge at locations of surface water and groundwater interaction (wetlands, ponds, and streams).Monitoring wells were sampled for major and minor ions, metals, and nutrients and a subset of wells was sampled for trace elements, dissolved gases

    2008-06-01

    Full Text Available Los cambios recientes y venideros en la docencia universitaria condicionarán cada vez más el empleo de herramientas nuevas y más originales en la enseñanza. En el ámbito de las ciencias biomédicas en particular existen ya experiencias previas sobre el uso del cine comercial como una manera de favorecer el debate y la formación en áreas y asignaturas diferentes. Este artículo sugiere el empleo de la película Mi tío de América a través de la experiencia en estudiantes de Biología, como una forma de presentar las teorías de Henri Laborit sobre la neurobiología de la organización social. Se trata de una película realizada en 1980, dirigida por Alain Resnais y con guión de Jean Gruault. La trama discurre a lo largo de la vida de tres personajes que viven situaciones diversas que permiten reflejar algunas de las teorías de Laborit. En ellas, básicamente se justifica la conducta humana a través de la jerarquización de tres estructuras cerebrales y niveles, desde el más primitivo y primario "arquiencéfalo", pasando por el paleoencéfalo, responsable de la memoria, hasta llegar a un nivel más sofisticado responsable de la conciencia, el neocórtex. La película pretende divulgar estas teorías y, para ello, emplea recursos diversos como imágenes de animales de experimentación en situaciones idénticas o similares a las vividas por los protagonistas. Si prestamos atención no sólo a las ventajas que puede ofrecer esta película para su empleo en la docencia sino también a algunas de las limitaciones propias de este filme, se podría concluir que Mi tío de América es altamente recomendable para la enseñanza en psiconeurobiología.The present and future changes in the teaching at the universities will advise for the use of new and more original methods. In the biomedical sciences there are some experiences regarding the use of popular movies to allow the discussion and interchange of points of view on some polemic topics

    Full Text Available L’échange épistolaire n’est pas le seul cadre discursif où l’on peut observer la façon dont des croyances axiologiques se trouvent justifiées. Quels avantages a-t-il pu présenter aux yeux des deux auteurs d’Ennemis publics, le philosophe Bernard-Henri Lévy et le romancier Michel Houellebecq ? La prise en charge de vérités autobiographiques et la notion de « littérature d’aveu » occupent une place centrale parmi ces avantages : elles nous permettront de problématiser la question de la lettre, « laboratoire de valeurs ». Le questionnement éthique auquel ils se livrent les incite ainsi à s’interroger sur leurs conceptions de la nature du sujet, de la responsabilité, de l’engagement et de l’action. On analysera, chemin faisant, quelques tropes spécifiques de leurs « visions du monde » antithétiques et on tentera de rendre compte du fait que leurs débats permettent de partager une aventure heuristique qui défige leurs images publiques respectives, objets de critiques virulentes de la part de nombreux journalistes et de commentateurs. L’évocation polémique de ces critiques joue certes un rôle important dans Ennemis publics, mais elle ne fera pas l’objet de cette contribution. On tentera ici de démontrer que cette correspondance met en œuvre et concrétise quelques-uns des concepts et des questionnements majeurs inhérents à la réflexion philosophique sur l’éthique.The epistolary genre is not the only discursive framework in which the justification of axiological beliefs can be observed and analyzed. Asking why it was selected by the authors of Ennemis publics, philosopher Bernard-Henri Lévy and novelist Michel Houellebecq, will enable us to present different aspects of their respective attitude towards the accountability for autobiographical truths. The ethical issues in which they indulge allow them to confront their own conception of the nature of the subject, of responsibility, of

Se expone en este artículo una síntesis del Estudio de Impacto Ambiental de un futuro aeródromo, actualmente en fase de proyecto, cuya vinculación al procedimiento administrativo de EIA, viene determinada por la legislación específica vigente en la actualidad: R.D. 1302/86. El documento técnico sobre el que se hace el estudio corresponde al plan especial del aeródromo. Un criterio básico en la concepción de aeropuertos y aeródromos privados es la compatibilidad con la habitabilidad del entorno y con las condiciones ecológicas y paisajísticas, criterio que debe intervenir en la orientación de las pistas, trayectorias en la maniobras de despegue y aterrizaje... incluso en la localización y diseño de estacionamientos, hangares y demás instalaciones. Esta idea aconseja concebir el proyecto con sensibilidad ambiental, desde las primeras fases, evitando repercutir la responsabilidad en este tema al estudio de impacto ambiental. Se adopta un estilo propio de la divulgación, en la idea de que más que los datos técnicos, que sólo interesan a la tramitación del proyecto, el lector encontrará mayor utilidad en los aspectos metodológicos y en aquéllos que han permitido al equipo redactor formar criterio sobre los costes y beneficios ambientales del proyecto y sobre la aceptabilidad de éste, en suma. Se ha utilizado una metodología clásica, de acuerdo con los requerimientos del reglamento de EIA.

    Full Text Available Résumé : Henri MICHAUX est à bien des égards un poète de la " situation ", au sens courant d'" ensemble des circonstances dans lesquelles une personne se trouve" (PETIT ROBERT, 2008 : 2379: les textes nous présentent souvent un être aux prises avec un monde agressif et impliqué dans des situations fâcheuses ; mais le sens premier, purement locatif du terme convient aussi parfaitement aux enjeux de son écriture : le " fait d'être en un lieu ", la " manière dont une chose est disposée, située ou orientée " (PETIT ROBERT, 2008 : 2379. C'est sur ce premier niveau sémantique que se fonde essentiellement l'étude qui va suivre. En prenant appui sur les deux textes-cadres que constituent le premier et le dernier poème du recueil La nuit remue, on se propose en effet d'observer une des manières dont se construit et se structure la relation à l'espace dans l'écriture michaldienne : autour du changement de situation. Ce changement - nous reprenons ici l'approche d'Andrée BORILLO dans son ouvrage La construction de l'espace en français- peut être de deux natures : le " changement d'emplacement ", où " le déplacement s'effectue tout en restant dans un même lieu établi ", et le " changement de lieu ", où se joue un véritable " changement de relation spatiale avec un lieu établi " (BORILLO, 1998 : 39. Nous avons choisi d'étudier conjointement ces deux modes de changement, les réunissant dans le cadre d'une exploration du principe de mobilité. Cette notion, on le verra, permet de rendre compte de bien des phénomènes à l'œuvre dans la poésie de MICHAUX : phénomènes d'ordre spatial, bien sûr, mais aussi d'ordre ontologique et linguistique. Les deux poèmes sélectionnés, " La nuit remue " et " L'avenir ", nous semblent des lieux tout désignés pour engager cette étude du principe de mobilité : il s'agit de textes-seuils, et en tant que tels, ils sont, dans l'ordre de la construction et de la lecture de l

    2005-01-01

    Full Text Available La Constitución de la República Oriental del Uruguay señala, en su Artículo 70: "El Estado propenderá al desarrollo de la investigación científica...". Sin embargo, la repatriación, a instancias de una organización de descendientes de indígenas autotitulados charrúas (ADENCH y con apoyo del Parlamento, de los restos del cacique charrúa Vaimaca Perú, muerto en cautividad en Francia en 1833, motivó controversias acerca de si los restos del mismo podían ser estudiados. Esta discusión no fue académica, si bien hubo derivaciones que influyeron sobre otras investigaciones, sino que fue suscitada por dicha organización la cual se opuso al estudio de los restos llegando a interponer varios recursos legales; uno de éstos, que condujo a un juicio, motivó un fallo histórico de un Tribunal de Apelaciones a favor del "interés general" por conocer "sin ataduras, sin secretos y sin misterios, la identidad de nuestro pueblo...". Sin embargo, y sin que se hiciera mención de dicha sentencia, el Parlamento aprobó posteriormente la Ley 17.767 que prohíbe expresamente la realización de "experimentos y estudios científicos" en los restos de Vaimaca Perú, violando según algunos autores, la propia Constitución y planteando, además de la discordancia entre dos Poderes del Estado, la oposición entre diversos intereses. A partir de estos hechos se propone analizar los valores éticos que subyacen a la investigación, si deben plantearse limitaciones a ésta y de ser así, cuáles, e incluso, cómo se debe normar sobre las mismas.

    2014-01-01

    Full Text Available Diseñar los planes de estudio en función del desarrollo de competencias demanda cambios metodológicos importantes. El método de caso es una de las estrategias de enseñanza y aprendizaje más adecuadas para desarrollar las competencias orientadas al trabajo en equipo y al fomento de la colaboración. El artículo que se presenta es un resumen del proyecto de innovación “El estudio de caso y el aprendizaje cooperativo en la universidad” (PIE-2010-2012 financiado por la Universidad del País Vasco. El objetivo general del proyecto es implementar el método de caso en las asignaturas de Organización de Centros (SocioEducativos (titulaciones de Pedagogía y Educación Social. MÉTODO: Se han seleccionado dos grupos de segundo curso de la titulación de Educación Social (uno en euskera y otro en castellano y otros dos del mismo curso de Pedagogía en ambos idiomas. En uno de los grupos de cada titulación se trabajaron técnicas de dinámica de grupo y en otro se desarrolló la estrategia del método de caso sin la ayuda de ellas. El alumnado evaluó la experiencia mediante un diario de grupo. RESULTADOS: Los datos indican que el alumnado está satisfecho con las actividades de aprendizaje realizadas en clase, las competencias de la titulación se desarrollan de manera satisfactoria y el funcionamiento de los grupos experimentales, en general, es mejor que el de los grupos control. La eficacia del trabajo grupal está estrechamente vinculada con variables de tipo relacional. DISCUSIÓN: La cooperación, la ayuda y la supervisión de tareas entre los miembros del grupo fomentan la interacción y el sentimiento de seguridad entre los estudiantes que tienen dificultades para lograr los objetivos de aprendizaje. Un alumno o alumna que se siente respaldado por su grupo a nivel académico, afectivo y relacional probablemente va a percibir un contexto de trabajo más seguro, inclusivo y acogedor.

    2017-01-01

    Full Text Available La Organización Mundial de la Salud ( OMS ha catalogado la obesidad infantil como la mayor crisis de la salud pública en el mundo. En su informe de 2014 indica que se registraron cuarenta y dos millones de niños menores de 5 años con sobrepeso; de ellos, treinta y cinco millones viven en países en desarrollo. La obesidad infantil es una enfermedad que tiene como origen una cadena causal compleja, de etiología multifactorial, en la que interactúan factores individuales y contextuales; en ellos el niño se encuentra inmerso, y ejercen influencia sobre su comportamiento, en diversos entornos y en diferentes niveles de jerarquía. Esta revisión presenta una descripción de algunos estudios y esfuerzos realizados para carac - terizar, prevenir y controlar la epidemia de obesidad en esta etapa del ciclo vital. Se propone, así mismo, un abordaje para el estudio de la obesidad, denominado ‘Enfoque de sistemas complejos’, el cual permite analizar cómo los factores individuales y contextuales se relacionan, y cómo esa interacción genera nuevas propiedades que no pueden explicarse a partir de los procedimientos habituales de análisis epidemiológico; para ello será necesario el trabajo en equipo, con enfoque multidisciplinario, que incluya médicos, pediatras, nutricionistas, epidemiólogos, salubristas, estadísticos, ingenieros, entre otros profesionales, que aporten sus conocimientos y habilidades, que permitan entender la obesidad como un fenómeno dinámi - co que requiere ser abordado con un enfoque integral e integrador, que trascienda la mirada reduccionista de los factores de riesgo del proceso salud – enfermedad. Solo entonces se podrá mejorar la capacidad para comprender la salud desde una perspectiva clásica hasta un sistema verdaderamente dinámico.

En 1994 se identificaron los genes BRCA1 (Breast Cancer Gene 1 y BRCA2 (Breast Cancer Gene 2 como susceptibles de cáncer de mama y ovario. En la actualidad se sabe que las mutaciones en BRCA1 y BRCA2 están lejos de explicar la totalidad de los casos de cáncer de mama y/o ovario, y a pesar de que se postulan alteraciones mutacionales en otros genes como CHEK2, TP53 y PTEN, el BRCA1 y BRCA2, siguen teniendo su importancia y utilidad en la valoración del riesgo de predisposición hereditaria. Aunque las cifras son variables según los distintos estudios y autores, se trata en cualquier caso de porcentajes importantes. Entre el 15 y el 85% de las mujeres portadoras de mutación BRCA 1 o BRCA 2 tienen riesgo de desarrollar un cáncer de mama y entre un 10 y 60% de desarrollar un cáncer de ovario.

    Jhony Alexander Villa-Ochoa

    2012-10-01

    Full Text Available En este artículo se usa el marco conceptual de Carlson et al. (2003 para discutir los resultados de un estudio de caso, el cual describe la forma como un estudiante razona covariacionalmente al enfrentarse a situaciones de variación asociadas a funciones cuadráticas. El estudio se ideó para desarrollar una línea convergente de indagación (Yin, 2009, la cual se centró en las descripciones que el estudiante realizaba a medida que abordaba las situaciones diseñadas para el estudio; dichas descripciones fueron trianguladas con las producciones escritas y los elementos teóricos. Desde las acciones que el estudiante evidenció, se pudo observar que el proceso de razonamiento covariacional no es un proceso lineal pero sí recursivo. Así mismo, este estudio de caso pone en evidencia el hecho de que existen estudiantes que pueden aproximarse a una interpretación variacional de las concavidades de una gráfica, sin que ello exija un estudio previo del cálculo diferencial. Del estudio se desprenden algunas implicaciones tanto para el marco conceptual abordado en este estudio como para el diseño de situaciones orientadas al aula de clase.

    Full Text Available En la mayoría de las investigaciones sobre la familia, los estudios se han centrado en las familias intactas o primeras familias. Sin embargo, es cada vez mayor el número de familias cuya configuración incluye un segundo matrimonio e hijos de una unión anterior (i.e. familias reconstituidas. En la consolidación del complejo proceso de ajuste de estas familias se han identificado unas fuentes comunes de estrés relacionadas principalmente con la formación de un nuevo sistema familiar. El objetivo de este artículo es realizar una revisión de las variables que inciden en el bienestar y/o malestar psicológico sobre una muestra de padrastros y madrastras españoles en el seno de estas nuevas configuraciones familiares. En una primera fase se realizaron, desde un diseño cualitativo, 20 entrevistas en profundidad a una muestra de padrastros y madrastras. En una segunda fase, se diseñó un cuestionario que fue respondido por 77 sujetos con la finalidad de analizar la posible relación entre alguna de las variables estudiadas.

    Full Text Available Objetivo: comparar las características sociodemográficas y de relación de cuidado de cuidadores de niños y adultos con enfermedades crónicas discapacitantes de Cartagena, Colombia. Método: estudio descriptivo, cuantitativo, de corte transversal. Se realizó un muestreo no probabilístico, por conveniencia, entre el 2006 y el 2007. Participaron 300 cuidadores: 98 de niños y 202 de adultos con enfermedades crónicas. Se utilizó la encuesta de caracterización de los cuidadores. Para describir las asociaciones entre las variables seleccionadas se empleó el análisis factorial de correspondencias múltiples. Resultados: ser cuidador de niños se asoció con ser padre o madre, ejercer el rol durante 37 meses o más, dedicarse a actividades del hogar y estar en unión libre. Ser cuidador de adultos se asoció con pacientes mayores, llevar 36 meses o menos como cuidador, ser hijo del paciente y estar casado. Conclusiones: las variables que mejor diferenciaron los dos grupos de cuidadores fueron nivel socioeconómico, estado civil y tiempo de dedicación al cuidado. El grupo de cuidadores de adultos presentó mayor variabilidad en las distintas categorías estudiadas.

    Full Text Available El objetivo de este estudio fue investigar la concentración de los componentes antioxidantes presentes en el tomate y la actividad antioxidante total durante su crecimiento, almacenamiento, maduración y comercialización. Los antioxidantes analizados fueron: licopeno, β-caroteno, ácido L-ascórbico y fenoles totales. La actividad antioxidante se midió utilizando los métodos: "Ferric reducing/antioxidant power" (FRAP y decoloración del β-caroteno. Los antioxidantes ácido L-ascórbico, licopeno y β-caroteno fueron 2,6 veces mayor en la comercialización respecto de los valores iniciales, mientras que la actividad antioxidante en la última etapa fue 2,1 y 3,5 veces más alta que en el crecimiento para los métodos FRAP y decoloración de b-caroteno, respectivamente. En consecuencia, el consumidor dispone de un fruto rico en antioxidantes, lo que le atribuye la capacidad de captación de los radicales libres presentes en nuestro cuerpo que podrían disminuir los riesgos que contraer enfermedades crónicas.

    Full Text Available En este trabajo exploramos la voz ‘periferia’ el contexto latinoamericano: cómo cambia tiempo que el fenómeno denotado se transforma y cómo agrega nuevos componentes en el diálogo entre la palabra y el fenómeno. Por ser una voz reciente, también revisamos otras voces emparentadas (‘arrabal’ y ‘suburbio’, reconstruyendo el uso y sentido cada una de ellas y la sustitución de unas otras hasta que aparece la palabra ‘periferia’. La expansión de las metrópolis y la constitución de amplios espacios periféricos sido de mucho interés en los estudios urbanos. No obstante, hay numerosos aspectos poco analizados. En el primer apartado revisamos voces antecedentes. Luego reconstruimos contexto en el que se comienza a referir territorio de expansión de la ciudad con palabra ‘periferia’, así como sus implicaciones en cuanto al sentido de la voz. En el apartado siguiente analizamos las dimensiones que incorporó la voz ‘periferia’ en relación procesos urbanos; para terminar con los desafíos actuales en torno a ese territorio las formas de nombrarlo

    2007-01-01

    Full Text Available Estudio de caso que explora la experiencia subjetiva del cuerpo en la trayectoria con el uso de drogas a través del relato de vida. Se utilizó la entrevista abierta bajo los supuestos metodológicos del relato autobiográfico. Se propuso al participante “Hablar de sí mismo y contar su experiencia con el uso de drogas”. La estrategia analítica se diseñó con base en la propuesta de Barthes (1990 para el análisis estructural de los relatos. Los resultados muestran que en el relato emerge una subjetividad que articula modos de haber sido y ser cuerpo como instancias constitutivas de la existencia. Desde el punto de vista de la corporalidad, la trayectoria con el uso de drogas deviene en una relación de saber-poder con el propio cuerpo, donde la experiencia subjetiva se entreteje en una red de controles y normas sociales. El análisis del cuerpo como experiencia enriquece la comprensión de prácticas como el uso de drogas.

  7. Generation of sub-part-per-billion gaseous volatile organic compounds at ambient temperature by headspace diffusion of aqueous standards through decoupling between ideal and nonideal Henry's law behavior.

    Kim, Yong-Hyun; Kim, Ki-Hyun

    2013-05-21

    In the analysis of volatile organic compounds in air, the preparation of their gaseous standards at low (sub-ppb) concentration levels with high reliability is quite difficult. In this study, a simple dynamic headspace-based approach was evaluated as a means of generating vapor-phase volatile organic compounds from a liquid standard in an impinger at ambient temperature (25 °C). For a given sampling time, volatile organic compound vapor formed in the headspace was swept by bypassing the sweep gas through the impinger and collected four times in quick succession in separate sorbent tubes. In each experiment, a fresh liquid sample was used for each of the four sampling times (5, 10, 20, and 30 min) at a steady flow rate of 50 mL min(-1). The air-water partitioning at the most dynamic (earliest) sweeping stage was established initially in accord with ideal Henry's law, which was then followed by considerably reduced partitioning in a steady-state equilibrium (non-ideal Henry's law). The concentrations of gaseous volatile organic compounds, collected after the steady-state equilibrium, reached fairly constant values: for instance, the mole fraction of toluene measured at a sweeping interval of 10 and 30 min averaged 1.10 and 0.99 nmol mol(-1), respectively (after the initial 10 min sampling). In the second stage of our experiment, the effect of increasing the concentrations of liquid spiking standard was also examined by collecting sweep gas samples from two consecutive 10 min runs. The volatile organic compounds, collected in the first and second 10 min sweep gas samples, exhibited ideal and nonideal Henry's law behavior, respectively. From this observation, we established numerical relationships to predict the mole fraction (or mixing ratio) of each volatile organic compound in steady-state equilibrium in relation to the concentration of standard spiked into the system. This experimental approach can thus be used to produce sub-ppb levels of gaseous volatile organic

    2009-01-01

    Full Text Available Este artículo aporta nuevas pruebas experimentales del efecto de estudiar economía en dos dimensiones de la cooperación social: la confianza y la reciprocidad. Estas dimensiones son aproximadas por medio del conocido juego de confianza. Empleando técnicas de muestreo e igualación (matching, y un reclutamiento de sujetos por invitación selectiva en vez de convocatoria abierta, el trabajo permite separar el efecto asociado al estudio de la economía del efecto asociado al potencial sesgo de selección en las preferencias de quienes escogen estudiar economía. La muestra está compuesta por estudiantes universitarios de economía y de otras carreras con escaso o nulo contenido de economía en Chile. Los resultados muestran que los montos enviados por los estudiantes de economía en la primera etapa del juego de confianza son significativamente menores en comparación con los estudiantes de otras carreras, lo que indica una menor propensión de los primeros a confiar en los demás. A su vez, encontramos una menor inclinación de los economistas a devolver los montos prometidos, lo que muestra una menor tendencia a la reciprocidad de la confianza depositada en ellos en el juego de confianza.

    2014-01-01

    Full Text Available Las limitantes del trabajo paleodemográfico, como la obtención de datos sobre la fecundidad de las sociedades antiguas, han impulsado el desarrollo de estrategias metodológicas para obtener esta información con algún grado de certeza. En este estudio contrastamos dos tipos de metodologías para obtener datos sobre fecundidad: la paleodemográfica basada en el análisis bioarqueológico de una serie esquelética maya prehispánica, utilizando el modelo de Weiss, y la metodología demográfica moderna aplicada a datos censales de Quintana Roo, con los que se calcularon varios indicadores de fecundidad. Los resultados muestran que el método estadístico que hemos aplicado en nuestras investigaciones permite tener un acercamiento confiable a los niveles de fecundidad y mortalidad que pudieron haber tenido estos grupos en el pasado, pues las estimaciones paleodemográficas presentan valores consistentes con la información obtenida de los censos, con un cálculo de cuatro a seis hijos para el grupo maya prehispánico de Chac Mool.

    2005-01-01

    Full Text Available El comportamiento de componentes de máquinas y de materiales necesita ser optimizado para reducir los costos de operación en las plantas industriales. Este hecho ha impulsado la Tribología, un área relacionada con el estudio de la fricción, la lubricación y el desgaste. Uno de los principales objetivos de esta área del conocimiento es elaborar modelos matemáticos para expresar la variación del desgaste durante el contacto de superficies en movimiento, con el fin de predecir la vida útil de los elementos de máquinas. El modelo de Archard para desgaste por deslizamiento en seco, formulado en 1953, es un modelo clásico que plantea una variación del desgaste inversamente proporcional a la dureza del material y directamente proporcional a la carga aplicada. En el presente trabajo, se ha utilizado el método de modelamiento de problemas físicos, propuesto por Asbhy, para analizar los modelos propuestos por Archard (Modelo de contactos múltiples en superficies rugosas y modelo de desgaste mecánico. Con base en él se ha podido realizar un análisis profundo a dichos modelos, mostrando un panorama más amplio del modelo de Archard; se discuten aspectos no mostrados en los textos y artículos de tribología, donde el tratamiento dado a este modelo resulta ser superficial, desconociendo las limitaciones y la perspectiva que tuvo Archard sobre los aspectos que deberían considerarse en un modelo de desgaste.

    1946-04-01

    Full Text Available Aunque en el territorio colombiano se han venido explotando los árboles caucheros del género Hevea durante casi medio siglo, solo ha sido en los últimos años cuando los botánicos han podido estudiar científicamente las especies en este país. En el presente artículo me limito a exponer de manera suscinta la identificación específica y la distribución geográfica del género Hevea en Colombia, valiéndome de las identificaciones botánicas preliminares que se han hecho hasta ahora, así como de los datos que he recogido personalmente y las informaciones que me han sido suministradas en fuentes fidedignas. Es de lamentarse la falta de exploración botánica en la hoya del río Inírida y sus afluentes que por ser, junto con el Guaviare, la región situada más al noreste de la zona de extensión del género Hevea, deja una laguna en los conocimientos que actualmente poseemos sobre la distribución geográfica de este género botánico. Igualmente carecemos de datos botánicos respecto de los ríos de menor importancia tales como el Yarí, el Cahuinarí y el Cotuhé, aunque sí los tenemos de las regiones mencionadas, lo mismo de otras vastas extensiones de la Amazonía Colombiana, podremos completar a satisfacción el estudio cuyo esbozo provisional presento en este trabajo.

    Full Text Available Se analizó el funcionamiento emocional (afecto positivo y negativo, satisfacción con la vida, soledad y estrategias de regulación de las personas centenarias en comparación con el de personas de menor edad (65-74, 75-84 y 85-94 años. Participaron en el estudio 257 personas mayores sin deterioro cognitivo y sin dependencia para las Actividades de la Vida Diaria (AVD. Los resultados revelaron que, en las personas centenarias, se producía una disminución de la afectividad positiva en comparación con los grupos de 65 a 74 años y de 75 a 84 años, pero no así con el de 85 a 94 años. Además, presentaban menor afecto negativo y más satisfacción con la vida (en comparación con el grupo de 65 a 74 años, al tiempo que manifestaban sentirse más solas (en comparación con los grupos de 65 a 74 años y de 75 a 84 años. Con respecto a las estrategias de regulación, en general, las personas centenarias utilizan en menor medida las estrategias proactivas y la solución de problemas y en mayor medida las pasivas, al menos en la regulación de la tristeza. En conclusión, a pesar de experimentar menos afecto positivo y más soledad se produce cierta disminución en el afecto negativo, e incluso cierto aumento de la satisfacción con la vida. En lo que respecta a la regulación emocional, las personas centenarias utilizan menos las estrategias proactivas y más las pasivas (tristeza.

    Full Text Available Objetivo: describir el concepto de cuerpo como parte de la investigación sobre la categoría disponibilidad corporal y su explicación para la fisioterapia. Material y métodos: investigación teórica, en la cual se aplicó el método fenomenológico para la definición de las categorías emergentes, se desarrollaron las fases de documentación, procesamiento analítico de los documentos e interpretación y construcción de subcategorías. Se empleó la técnica de análisis documental a una muestra de 59 documentos de 82 reunidos. Como criterio de validez interna para el proceso de interpretación se efectuó lectura de los documentos por parte de cada una de las investigadoras y posterior contrastación. Resultados: se identificaron dos enfoques interpretativos, el monismo y el dualismo, que generan relaciones centradas en la condición material o espiritual del cuerpo. Desde el dualismo, el estudio del cuerpo en la profesión se dirige a su capacidad funcional y adaptación orgánica; desde el monismo, la fisioterapia reconoce al cuerpo con respecto a su condición de lenguaje, de interacción social y de conciencia. Conclusiones: se reconoce el cuerpo como un lenguaje humano con implicaciones teóricas y metodológicas para la profesión. Ello exige integrar los aspectos orgánicos, simbólicos y psíquicos del cuerpo, en los procesos de formación de pregrado y avanzada.

    Full Text Available Antecedentes: Los estudios clínicos son un tipo de investigación que ayudan a la ciencia médica a encontrar nuevas formas de prevenir, detectar, diagnosticar o tratar enfermedades y hoy en día son los estudios que aportan la mayor evidencia científica frente al uso de nuevas terapias farmacológicas. Objetivo: Describir la situación actual de los estudios clínicos en Colombia. Métodos: Se consultaron las bases de datos de registro de estudios clínicos, se realizó una revisión de los aspectos regulatorios y la normatividad relacionada. Resultados: no es posible determinar la cantidad exacta de estudios clínicos registrados en Colombia debido a que no se cuenta con un sistema de registro. Los estudios clínicos registrados difieren en las bases de datos consultadas. Desde 1995 a 2013 se identificaron 738 ensayos únicos, el 90% de ellos fueron patrocinados por industrias farmacéuticas, 62% fueron fase III y se han desarrollado principalmente en enfermedades crónicas como el cáncer, las enfermedades cardiovasculares y las degenerativas. Conclusiones: Colombia carece de un sistema de registro de estudios clínicos que permita realizar un seguimiento adecuado por parte de la comunidad y los profesionales de la salud. Debido a que el mayor porcentaje de estos estudios han sido patrocinados por la Industria Farmacéutica, se hace necesario fomentar y desarrollar estrategias que permitan el desarrollo de investigación propia

    Full Text Available El presente trabajo tuvo como propósito conocer el nivel de resiliencia en una muestra de estudiantes universitarios de una institución de educación superior pública del estado de Jalisco, México. Además de ello, se analizó la relación y diferencia entre la resiliencia y las variables de sexo, edad y nivel socioeconómico. Para medir la variable de interés se utilizó la Escala de Resiliencia desarrollada por Wagnild y Young (1993 en su versión traducida y adaptada al español por Heilemann, Lee y Kury (2003, la cual está constituida por 25 reactivos en escalamiento tipo Likert. Los resultados muestran niveles altos de resiliencia en los estudiantes universitarios, no encontrándose diferencias significativas entre las variables carrera, sexo y edad de los estudiantes. Se concluye que la resiliencia alta es una característica muy generalizada en la mayoría de los estudiantes universitarios. Finalmente, se sugiere la ampliación de la línea de investigación con otros tamaños muestrales y otro tipo de carreras, así como la ejecución de trabajos que relacionen a la resiliencia con otras variables psicosociales no contempladas en el estudio.

    Eduardo B. Arribalzaga

    Full Text Available Introducción: existen actualmente "agujeros negros" en la transmisión de conocimientos aplicables que obligan a poner atención en los mecanismos de adquisición de destrezas y habilidades. El objetivo es evaluar características cualitativas de las habilidades en 2 tipos de procedimientos técnicos básicos al alcance de un cirujano general. Material y Métodos: estudio preliminar exploratorio observacional prospectivo en un Hospital Universitario consistente en la observación de los pasos de una toracotomía axilar o una dermolipectomía abdominal anterior con neo ombligo. Se analizó la práctica de las operaciones programadas, no discriminando que médicos residentes las habían efectuado. Los datos se medían en una lista de cotejos con una escala tipo Likert modificada de 3 items. Cada paso de la técnica observada era evaluado sin considerar el tiempo de duración de cada maniobra. Los evaluadores eran ajenos al equipo quirúrgico actuante ubicados donde no se los veía (en miradores para evitar sesgos o maniobras que afectaran la actividad. Se usaron pruebas estadísticas de ANOVA y prueba de t para detectar validez y diferencias en los resultados. Resultados: observada una toracotomía, todos los pasos quirúrgicos fueron evaluados por encima del valor 2 (bueno, sin variaciones en el desarrollo de cada paso ni existir diferencias significativas en la comparación de destrezas. Similares resultados se hallaron en la observación de la otra técnica. Conclusiones: con un sencillo método de observación directa inadvertida por el evaluado con criterios específicos se hizo un diagnóstico de situación demostrando la existencia de habilidades adquiridas en cirujanos en formación durante programas de residencia.

    Full Text Available This work analyses the area of materials science. Materials science has existed since the earliest civilizations. The development and evolution of societies has been intimately linked to the ability of their members to produce and shape materials to meet their needs. However, materials science has only recently been established as a recognised academic discipline, a consequence of the agglomeration of different areas of science. The citation habits and scientograms associated with this field could therefore be related to the scientific tradition and culture of each country. In this study, the citation networks of six of the most developed countries in the year 2002 were examined using a new technique that graphically represents these networks as scientograms. The technique makes use of cocitation between topic categories of the JCR to generate a network of categories which is graphically represented. The scientograms obtained, which represent the citation networks of each country examined, reflect the cultures of the different nations studied.

    En este trabajo se analiza la clase Ciencia de los Materiales presente desde las civilizaciones más antiguas ya que el desarrollo y la evolución de las sociedades siempre han estado íntimamente vinculados a la capacidad que han tenido sus miembros para producir y conformar los materiales necesarios para satisfacer sus necesidades, pero como disciplina se ha establecido de manera muy reciente por la aglomeración de distintas categorías científicas pertenecientes a otras áreas. Por los que los hábitos de citación y los scientogramas podrían estar relacionados con la tradición y cultura de la ciencia existente en cada país en el año estudiado. Para realizar el estudio hemos utilizado las redes de citación de seis de los países más desarrollados en el año 2002, utilizando una técnica novedosa que las representa gráficamente mediante unos gráficos denominados scientogramas.
