  1. Molecular Robots Obeying Asimov's Three Laws of Robotics. (United States)

    Kaminka, Gal A; Spokoini-Stern, Rachel; Amir, Yaniv; Agmon, Noa; Bachelet, Ido


    Asimov's three laws of robotics, which were shaped in the literary work of Isaac Asimov (1920-1992) and others, define a crucial code of behavior that fictional autonomous robots must obey as a condition for their integration into human society. While, general implementation of these laws in robots is widely considered impractical, limited-scope versions have been demonstrated and have proven useful in spurring scientific debate on aspects of safety and autonomy in robots and intelligent systems. In this work, we use Asimov's laws to examine these notions in molecular robots fabricated from DNA origami. We successfully programmed these robots to obey, by means of interactions between individual robots in a large population, an appropriately scoped variant of Asimov's laws, and even emulate the key scenario from Asimov's story "Runaround," in which a fictional robot gets into trouble despite adhering to the laws. Our findings show that abstract, complex notions can be encoded and implemented at the molecular scale, when we understand robots on this scale on the basis of their interactions.

  2. ISAAC. An Appreciation (United States)

    Spyromilio, J.; Cuby, J.; Lidman, C.; Johnson, R.; Jaunsen, A. O.; Mason, E.; Ivanov, V. D.; Schmidtobreick, L.


    ISAAC was switched off, almost certainly for the final time, on 12 December 2013. The last observing block executed was OB1030962, the target, Supernova 2013ct, for a programme whose principal investigator just happened to be the first instrument scientist for ISAAC. "All constraints were respected and spectra of the target detected" are the public comments in the log. A short history of ISAAC, from the instrument scientists' viewpoint, is presented.

    Moffat, John W


    John W. Moffat was a poor student of math and science. That is, until he read Einstein's famous paper on general relativity. Realizing instantly that he had an unusual and unexplained aptitude for understanding the complex physics described in the paper, Moffat wrote a letter to Einstein that would change the course of his life. Einstein Wrote Back tells the story of Moffat's unusual entry into the world of academia and documents his career at the frontlines of twentieth-century physics as he worked and associated with some of the greatest minds in scientific history, including Niels Bohr,

    Isaac Newton had an extraordinary idea. He believed the physical universe and everything in it could be described in exact detail using mathematical relationships. He formulated a law of gravity that explained why objects fall downwards, how the moon causes the tides, and why planets and comets orbit the sun. While Newton's work has been added to over the years, his basic approach remains at the heart of the scientific worldview. Yet Newton's own had little in common with that of a modern scientist. He believed the universe was created to a precise and rational design - a design that was fully

    Gilbert, Robert; Wen, Guo-Chun


    This volume of the Proceedings of the congress ISAAC '97 collects the contributions of the four sections 1. Function theoretic and functional analytic methods for pde, 2. Applications of function theory of several complex variables to pde, 3. Integral equations and boundary value problems, 4. Partial differential equations. Most but not all of the authors have participated in the congress. Unfortunately some from Eastern Europe and Asia have not managed to come because of lack of financial support. Nevertheless their manuscripts of the proposed talks are included in this volume. The majority of the papers deal with complex methods. Among them boundary value problems in particular the Riemann-Hilbert, the Riemann (Hilbert) and related problems are treated. Boundary behaviour of vector-valued functions are studied too. The Riemann-Hilbert problem is solved for elliptic complex equations, for mixed complex equations, and for several complex variables. It is considered in a general topological setting for mapping...

    Full Text Available Die geweldige oplewing van die Christelike wetenskaps- gedagte in ons geeslose tyd, is ongetwyfeld ’n haas onverklaar- bare verskynsel. Dwarsdeur die eeue het Christene ook wetenskap beoefen saam met ongelowiges, maar dit was eers in ons leeftyd dat die principia van die Christelike religie ook vrugbaar gemaak is vir die wetenskapsbeoefening. In hierdie verband sal die name van Dooyeweerd, Vollenhoven, Stoker e.a. steeds met eer vermeld word. Natuurlik het belydende Christene ook voorheen wel deeglik saamgewerk aan die gebou van die wetenskap. Die intieme verband tussen religie, wysbegeerte en wetenskaps­ beoefening is toe egter nog nie suiwer ingesien nie. Uit hier­ die tydperk dateer die arbeid van sir Isaac Newton.

  14. Newton's apple Isaac Newton and the English scientific renaissance

    CERN Document Server

    Aughton, Peter


    In the aftermath of the English Civil War, the Restoration overturned England's medieval outlook and a new way of looking at the world allowed the genius of Isaac Newton (b. 1642) and his contemporaries to flourish. Newton had a long and eventful life apart from his scentific discoveries. He was born at the beginnings of the Civil War, his studies were disrupted by the twin disasters of the Great Plague and the Fire of London; a brilliant and enigmatic genius, Newton dabbled in alchemy, wrote over a million words on the Bible, quarrelled with his contemporaries and spent his last years as Master of the Royal Mint as well as President of the Royal Society. This book sets Newton's life and work against this dramatic intellectual rebirth; among his friends and contemporaries were Samuel Pepys, the colourful diarist, John Evelyn, the eccentric antiquarian, the astronomers Edmund Halley and John Flamsteed, and Christopher Wren, the greatest architect of his age. They were all instrumental in the founding of the Ro...

  17. Isaac Newton and the astronomical refraction. (United States)

    Lehn, Waldemar H


    In a short interval toward the end of 1694, Isaac Newton developed two mathematical models for the theory of the astronomical refraction and calculated two refraction tables, but did not publish his theory. Much effort has been expended, starting with Biot in 1836, in the attempt to identify the methods and equations that Newton used. In contrast to previous work, a closed form solution is identified for the refraction integral that reproduces the table for his first model (in which density decays linearly with elevation). The parameters of his second model, which includes the exponential variation of pressure in an isothermal atmosphere, have also been identified by reproducing his results. The implication is clear that in each case Newton had derived exactly the correct equations for the astronomical refraction; furthermore, he was the first to do so.

  18. Improvement of core degradation model in ISAAC

    International Nuclear Information System (INIS)

    Kim, Dong Ha; Kim, See Darl; Park, Soo Yong


    If water inventory in the fuel channels depletes and fuel rods are exposed to steam after uncover in the pressure tube, the decay heat generated from fuel rods is transferred to the pressure tube and to the calandria tube by radiation, and finally to the moderator in the calandria tank by conduction. During this process, the cladding will be heated first and ballooned when the fuel gap internal pressure exceeds the primary system pressure. The pressure tube will be also ballooned and will touch the calandria tube, increasing heat transfer rate to the moderator. Although these situation is not desirable, the fuel channel is expected to maintain its integrity as long as the calandria tube is submerged in the moderator, because the decay heat could be removed to the moderator through radiation and conduction. Therefore, loss of coolant and moderator inside and outside the channel may cause severe core damage including horizontal fuel channel sagging and finally loss of channel integrity. The sagged channels contact with the channels located below and lose their heat transfer area to the moderator. As the accident goes further, the disintegrated fuel channels will be heated up and relocated onto the bottom of the calandria tank. If the temperature of these relocated materials is high enough to attack the calandria tank, the calandria tank would fail and molten material would contact with the calandria vault water. Steam explosion and/or rapid steam generation from this interaction may threaten containment integrity. Though a detailed model is required to simulate the severe accident at CANDU plants, complexity of phenomena itself and inner structures as well as lack of experimental data forces to choose a simple but reasonable model as the first step. ISAAC 1.0 was developed to model the basic physicochemical phenomena during the severe accident progression. At present, ISAAC 2.0 is being developed for accident management guide development and strategy evaluation. In

  6. Restless Gentleman: Jorge Isaacs in Nineteenth-Century Colombia

    Directory of Open Access Journals (Sweden)

    Marco Palacios


    Full Text Available María (1867 is one of the most widely read Spanish-American novels of all times; this work compares it to the ups and downs in its author's life. Jorge Isaacs had been rich and fallen on hard times; had been a conservative Catholic and turned into an anti-clerical liberal; had been a merchant and rose up in arms; later he was exiled from his native province. The parable of his life deserves an explanation and this paper offers two clues: Isaacs' ineptitude for business and the high price he had to pay for changing his political-ideological sign into one that ten years later opposed the political regime of La Regeneración (1878-1900. Ironically, a later conservative regime (1900-1930 crafted the literary canonization of María, a nostalgic and sentimental novel, and established it as a national model of immutable private morality.

  8. From the Landgrave in Kassel to Isaac Newton (United States)

    Høg, E.


    Landgrave Wilhelm IV established in 1560 the first permanent astronomical observatory in Europe. When he met the young Tycho Brahe in 1575 he recognized the genius and recommended him warmly to the Danish king Frederik II. Wilhelm and Tycho must share the credit for renewing astronomy with very accurate observations of positions of stars by new instrumentation and new methods. Tycho's observations of planets during 20 years enabled Johannes Kepler to derive the laws of planetary motion. These laws set Isaac Newton in a position to publish the laws of physical motion and universal gravitation in 1687 - the basis for the technical revolution.

  11. Hurricane Isaac: observations and analysis of coastal change (United States)

    Guy, Kristy K.; Stockdon, Hilary F.; Plant, Nathaniel G.; Doran, Kara S.; Morgan, Karen L.M.


    Understanding storm-induced coastal change and forecasting these changes require knowledge of the physical processes associated with a storm and the geomorphology of the impacted coastline. The primary physical process of interest is sediment transport that is driven by waves, currents, and storm surge associated with storms. Storm surge, which is the rise in water level due to the wind, barometric pressure, and other factors, allows both waves and currents to impact parts of the coast not normally exposed to these processes. Coastal geomorphology reflects the coastal changes associated with extreme-storm processes. Relevant geomorphic variables that are observable before and after storms include sand dune elevation, beach width, shoreline position, sediment grain size, and foreshore beach slope. These variables, in addition to hydrodynamic processes, can be used to quantify coastal change and are used to predict coastal vulnerability to storms (Stockdon and others, 2007). The U.S. Geological Survey (USGS) National Assessment of Coastal Change Hazards (NACCH) project ( provides hazard information to those concerned about the Nation’s coastlines, including residents of coastal areas, government agencies responsible for coastal management, and coastal researchers. Extreme-storm research is a component of the NACCH project ( that includes development of predictive understanding, vulnerability assessments using models, and updated observations in response to specific storm events. In particular, observations were made to determine morphological changes associated with Hurricane Isaac, which made landfall in the United States first at Southwest Pass, at the mouth of the Mississippi River, at 0000 August 29, 2012 UTC (Coordinated Universal Time) and again, 8 hours later, west of Port Fourchon, Louisiana (Berg, 2013). Methods of observation included oblique aerial photography

  12. Gustave Flaubert, Charles Dickens, and Isaac Pulvermacher's "magic band". (United States)

    Waits, Robert K


    Around 1850, Isaac L. Pulvermacher (1815-1884) joined the ranks of so-called "galvanists" who had, for nearly a century, been touting the shocks and sparks of electricity as a miracle cure for all ills, including neurological complaints such as palsy and hemiplegia. The famed authors, Gustave Flaubert (1821-1880), in France, and Charles Dickens (1812-1870), in England, although contemporaries, apparently never met or corresponded. But during their lives, they both became aware of Pulvermacher and his patented Hydro-Electric Chains, claimed to impart vigor and cure nearly every complaint. Pulvermacher's chains made a cameo appearance in Madame Bovary (1857), Flaubert's controversial (and most successful) novel. Among Dickens's last letters (1870) was an order for I. L. Pulvermacher and Company's "magic band." Since the Victorian age, electrical and magnetic cures, for better or worse, continue to be products of both the medical profession and quackery. © 2013 Elsevier B.V. All rights reserved.

  13. The Service Programme of the Isaac Newton Group of Telescopes (United States)

    Méndez, J.


    The Service Programme of the Isaac Newton Group of Telescopes (Roque de los Muchachos Observatory, La Palma, Spain) aims at providing astronomers with a rapid and flexible tool for obtaining small sets of observations on the William Herschel Telescope up to 8 hours. This can be used to try new ideas or complement a regular observing programme allocated on the ING telescopes, for instance. Proposals are accepted from principal investigators working in an institution located in the United Kingdom, the Netherlands or Spain, but also regardless the nationality of the host institution. A monthly deadline for application submission takes place at midnight on the last day of each month but urgent requests submitted at any time can also be accepted. Proposals are generally withdrawn from the scheme after a one year period. In this poster we provide an overview of the programme and some statistics. More information can be obtained at

  14. "To Improve upon Hints of Things": Illustrating Isaac Newton. (United States)

    Schilt, Cornelis J


    When Isaac Newton died in 1727 he left a rich legacy in terms of draft manuscripts, encompassing a variety of topics: natural philosophy, mathematics, alchemy, theology, and chronology, as well as papers relating to his career at the Mint. One thing that immediately strikes us is the textuality of Newton's legacy: images are sparse. Regarding his scholarly endeavours we witness the same practice. Newton's extensive drafts on theology and chronology do not contain a single illustration or map. Today we have all of Newton's draft manuscripts as witnesses of his working methods, as well as access to a significant number of books from his own library. Drawing parallels between Newton's reading practices and his natural philosophical and scholarly work, this paper seeks to understand Newton's recondite writing and publishing politics.

  15. First Images and Spectra from ISAAC on UT1 (United States)


    New VLT Instrument Delivers Spectacular Infrared Views of the Southern Sky The VLT Infrared Spectrometer And Array Camera (ISAAC) [1] was installed at the first 8.2-m VLT Unit Telescope (UT1) on November 14, 1998, cf. ESO PR Photos 42a-h/98. ISAAC is the second major VLT instrument to be installed at the VLT and the first to be fully designed and developed at ESO within its Instrumentation Division. Following evacuation of its large vacuum vessel, cooling to cryogenic temperature and alignment with the telescope according to the planned schedule, it successfully achieved technical first light during the night between November 16 and 17, 1998. ESO PR Photo 46a/98 ESO PR Photo 46a/98 [JPEG: 800 x 847 pix - 432k] [High-Res - JPEG: 3000 x 3175 pix - 2.9Mb] PR Photo 46a/98 shows ISAAC as it is now mounted at the UT1 Nasmyth B adaptor-rotator (right; blue colour). The co-rotator system (left) through which the various cables are fed to the instrument, is also well visible. (Photo obtained on November 16, 1998). The first focus tests on stars yielded images of excellent sharpness, around 0.45 arcsec full-width-half-maximum (FWHM). During the following nights, even better images, as small as 0.25 arcsec in relatively short exposures, were obtained, testifying to the quality of the site as well as the optical quality of both the telescope and instrument. Observations were executed using the new VLT Control and Data Flow Systems which are driven by Observation Blocks that define all details of the required astronomical exposures. In addition to direct images in various infrared colours (selected with different optical filters), spectroscopic observations were also made during the first few nights of operation. This Press Release is accompanied by several images and spectra which illustrate some of the exceptional new astronomical capabilities offered by this instrument.

    We establish a new type of backward stochastic differential equations (BSDEs) connected with stochastic differential games (SDGs),namely,BSDEs strongly coupled with the lower and the upper value functions of SDGs,where the lower and the upper value functions are defined through this BSDE.The existence and the uniqueness theorem and comparison theorem are proved for such equations with the help of an iteration method.We also show that the lower and the upper value functions satisfy the dynamic programming principle.Moreover,we study the associated Hamilton-Jacobi-Bellman-Isaacs (HJB-Isaacs) equations,which are nonlocal,and strongly coupled with the lower and the upper value functions.Using a new method,we characterize the pair (W,U) consisting of the lower and the upper value functions as the unique viscosity solution of our nonlocal HJB-Isaacs equation.Furthermore,the game has a value under the Isaacs' condition.

    We present a description of a new instrument development, HARPS3, planned to be installed on an upgraded and roboticized Isaac Newton Telescope by end-2018. HARPS3 will be a high resolution (R≃115,000) echelle spectrograph with a wavelength range from 380-690 nm. It is being built as part of the Terra Hunting Experiment - a future 10- year radial velocity measurement programme to discover Earth-like exoplanets. The instrument design is based on the successful HARPS spectrograph on the 3.6m ESO telescope and HARPS-N on the TNG telescope. The main changes to the design in HARPS3 will be: a customised fibre adapter at the Cassegrain focus providing a stabilised beam feed and on-sky fibre diameter ≍1:4 arcsec, the implementation of a new continuous ow cryostat to keep the CCD temperature very stable, detailed characterisation of the HARPS3 CCD to map the effective pixel positions and thus provide an improved accuracy wavelength solution, an optimised integrated polarimeter and the instrument integrated into a robotic operation. The robotic operation will optimise our programme which requires our target stars to be measured on a nightly basis. We present an overview of the entire project, including a description of our anticipated robotic operation.

  2. 'Speaking Kleinian': Susan Isaacs as Ursula Wise and the Inter-War Popularisation of Psychoanalysis. (United States)

    How did the complex concepts of psychoanalysis become popular in early twentieth-century Britain? This article examines the contribution of educator and psychoanalyst Susan Isaacs (1885-1948) to this process, as well as her role as a female expert in the intellectual and medical history of this period. Isaacs was one of the most influential British psychologists of the inter-war era, yet historical research on her work is still limited. The article focuses on her writing as 'Ursula Wise', answering the questions of parents and nursery nurses in the popular journal Nursery World, from 1929 to 1936. Researched in depth for the first time, Isaacs' important magazine columns reveal that her writing was instrumental in disseminating the work of psychoanalyst Melanie Klein in Britain. Moreover, Isaacs' powerful rebuttals to behaviourist, disciplinarian parenting methods helped shift the focus of caregivers to the child's perspective, encouraging them to acknowledge children as independent subjects and future democratic citizens. Like other early psychoanalysts, Isaacs was not an elitist; she was in fact committed to disseminating her ideas as broadly as possible. Isaacs taught British parents and child caregivers to 'speak Kleinian', translating Klein's intellectual ideas into ordinary language and thus enabling their swift integration into popular discourse.

  3. [The Galenic content of Isaac Beeckman's medical ideas (1617-1629)]. (United States)

    Moreau, Elisabeth


    The Journal tenu par Isaac Beeckman de 1604 à 1634 has been studied in the history of the seventeenth-century scientific revolution following the theme of Isaac Beeckman's physical mathematical mechanistic view, his proto-molecular theory and his atomistic Lucretian influence. This article goes deeper into the medical ideas of the Journal: how Isaac Beeckman (1588-1637) settles the structure of living matter according to his intensive reading of Galen. It develops a different analysis from the traditionally triumphalist approach in the history of science, focused on the victory of Cartesian mechanism, particularly in the history of medicine taking up Galenism very briefly because of its obsolete physiology. The Galenic corpus inside Isaac Beeckman's Journal consists of the many commentaries of Galen which Beeckman has put down in writing since 1616 until 1627, after when the passages linked to Galen became fewer. Isaac Beeckman's study of Galenic medicine is analyzed according to three approaches: the teleological dimension of Galenism showing up the organic conception of human body corresponding to the divine Providence and consistent with Beeckman's Calvinist belief, the physiologic angle of Galenism, based on natural faculties, stressing the purely speculative aspect of Beeckman's commentaries, while the pathologic and therapeutic angle supports the Hippocratic humourism influence.

  4. Isaacs' syndrome in a patient with dermatomyositis: case report and review of the literature. (United States)

    This is a case report of Isaacs' syndrome in dermatomyositis. The patient presented with proximal muscle weakness, rash, elevated muscle enzyme, myopathic electromyograph and typical muscle biopsy. Ultimately he developed typical symptoms of Isaacs' syndrome which is an autoimmune channelopathy from voltage gated potassium channel antibody (anti-VGKC) leading to dysfunction of axonal discharge at neuromuscular junctions. It shares some similar characteristics with dermatomyositis such as autoimmunity, its association with malignancy and the response to treatment. © 2016 Asia Pacific League of Associations for Rheumatology and John Wiley & Sons Australia, Ltd.

    Full Text Available The aim of this study was to assess asthma prevalence in children between 13-14 years of age in East Jakarta. This study is a cross sectional study which surveyed 2234 high school students between the ages of 13 and 14 years in East Jakarta in 2001 using the ISAAC questionnaire. Bronchial challenge test was applied by using methacholine substance to 186 students. Reports based on the ISAAC questionnaire indicate that 7.2% of teenage have had wheezing experience, 4.1% have wheezing within the last 12 months, 1.8% have ever suffered severe asthma attack within the last 12 months, 3.3% have suffered wheezing after exercise, and 6.3% have got night cough while they were not suffering from cold. Prevalence of atopy diseases such as rhinitis and eczema were 14.2% and 3.9%, meanwhile rhinitis and eczema prevalence within the last 12 months according to this study were 10.6% and 2.9% respectively. Statistically, there is a significant correlation between wheezing symptom and atopy (p < 0.05. From indepth questionnaire, a significant value of kappa 0.84 related with wheezing within the last 12 months was found. Bronchial challenge test results indicate that sensitivity was 90%, specificity 83.58%, positive predictive value 68.12% and negative predictive value was 95.73%. Asthma prevalence in East Jakarta at 2001 based on ISAAC questionnaire was 8.9%, and cumulative prevalence 11.5%.

    Jaime Ocampo


    Full Text Available Currently, the ISAAC (International Study of Asthma and Allergies in Childhood project is a global approach to assess the prevalence of asthma and other allergies in different latitudes. One of the great advantages of this project is that it compares using the same methodology, the prevalence of asthma in more than 50 cities during the same period of time, nevertheless the reproducibility of these results when compared with other studies of prevalence in each region has not been evaluated. In this review we aim to compare the epidemiological data provided by the ISAAC against the data identified in some regional cohort studies and by means of a critical evaluation to highlight the main similarities and to analyze the differences between these epidemiological data.

  7. Intermittent Solar Ammonia Absorption Cycle (ISAAC) refrigeration for lesser developed countries (United States)

    Erickson, Donald C.


    The Intermittent Solar Ammonia Absorption Cycle (ISAAC) refrigerator is a solar thermal technology which provides low cost, efficient, reliable ice-making to areas without ready access to electricity. An ISAAC refrigeration system consists of a compound parabolic solar collector, two pressure vessels, a condenser, a cold box or refrigerated space, and simple connective piping -- no moving parts or electrical components. Most parts are simple construction or plumbing grade materials, locally available in many remote areas. This technology has numerous potential benefits in lesser developed countries both by providing a cheap, reliable source of ice, and, since manufacture requires only semi-skilled labor, a source of employment to the local economy. Applications include vaccine storage for health care clinics; fish, meat, and dairy product storage; and personal consumption. Importantly, this technology increases the quality of life for people in lesser developed countries without depleting fossil fuel resources or increasing the release of greenhouse gases such as CO2 and chlorofluorocarbons.

  8. The Work of John Isaac Plummer at Orwell Park Observatory in the years 1874 to 1890 (United States)

    Whiting, P. J.


    This paper builds on the unpublished collation by the Orwell Astronomical Society entitled John Isaac Plummer. It takes the form of a chronology and critique of papers published by John Isaac Plummer (1844-1925) in the Monthly Notices of the Royal Astronomical Society and Astronomische Nachrichten on work undertaken at the Orwell Park Observatory, Ipswich, in the years 1874 to 1890. This work, mainly, although not exclusively, in England, took the form of measuring the positions and deriving the orbits of as many comets as could be observed from Orwell Park. Plummer also published papers in other journals, such as Nature and The Observatory, but these are to be the subject of future research.

  10. How to manage a revolution: Isaac Newton in the early twentieth century (United States)

    Clarke, Imogen


    In the first half of the twentieth century, dramatic developments in physics came to be viewed as revolutionary, apparently requiring a complete overthrow of previous theories. British physicists were keen to promote quantum physics and relativity theory as exciting and new, but the rhetoric of revolution threatened science's claim to stability and its prestigious connections with Isaac Newton. This was particularly problematic in the first decades of the twentieth century, within the broader context of political turmoil, world war, and the emergence of modernist art and literature. This article examines how physicists responded to their cultural and political environment and worked to maintain disciplinary connections with Isaac Newton, emphasizing the importance of both the old and the new. In doing so they attempted to make the physics ‘revolution’ more palatable to a British public seeking a sense of permanence in a rapidly changing world.

  11. Severe Accident Progression and Consequence Assessment Methodology Upgrades in ISAAC for Wolsong CANDU6

    International Nuclear Information System (INIS)

    Song, Y.M.; Kim, D.H.; Nijhawan, Sunil


    Amongst the applications of integrated severe accident analysis codes like ISAAC, the principal are to a) help develop an understanding of the severe accident progression and its consequences; b) support the design of mitigation measures by providing for them the state of the reactor following an accident; and c) to provide a training platform for accident management actions. After Fukushima accident there is an increased awareness of the need to implement effective and appropriate mitigation measures and empower the operators with training and understanding about severe accident progression and control opportunities. An updated code with reduced uncertainties can better serve these needs of the utility making decisions about mitigation measures and corrective actions. Optimal deployment of systems such as PARS and filtered containment venting require information on reactor transients for a number of critical parameters. Thus there is a greater consensus now for a demonstrated ability to perform accident progression and consequence assessment analyses with reduced uncertainties. Analyses must now provide source term transients that represent the best in available understanding and so meaningfully support mitigation measures. This requires removal of known simplifications and inclusion of all quantifiable and risk significant phenomena. Advances in understanding of CANDU6 severe accident progression reflected in the severe accident integrated code ROSHNI are being incorporated into ISAAC using CANDU specific component and system models developed and verified for Wolsong CANDU 6 reactors. A significant and comprehensive upgrade of core behavior models is being implemented in ISAAC to properly reflect the large variability amongst fuel channels in feeder geometry, fuel thermal powers and burnup. The paper summarizes the models that have been added and provides some results to illustrate code capabilities. ISAAC is being updated to meet the current requirements and

    Full Text Available Jorge Isaacs es conocido por María (1867, novela cumbre del romanticismo americano. Pero Isaacs, además, fue un político liberal radical que llevó adelante una revolución, en enero de 1880, movido por sus principios ideológicos en medio de lo que él consideraba la traición de los liberales. La revolución, embebida de romanticismo, fue una empresa romántica destinada al fracaso desde un principio. Este artículo, a partir del estudio de los documentos de la época, analiza de qué manera Isaacs desarrolló sus actividades militantes, como superintendente de Educación, primero, como congresista, después, y como revolucionario, en el marco del proceso de recuperación del poder por parte de los conservadores. Asimismo, este artículo se enfoca en el espíritu romántico que animó a Isaacs y cómo se expresó a través de la palabra encendida de los manifiestos, proclamas, cartas e informes recopilados por el propio Isaacs en su libro La revolución radical en Antioquia (1880.   Jorge Isaacs is well-known for Maria (1867, which is considered the most important novel of Latin American romanticism.

    David van der Linden


    Full Text Available After the revocation of the Edict of Nantes in 1685, over 400 Huguenot ministers made their way to the Dutch Republic in search of a new pulpit. They stood a good chance, because the Huguenot exodus resulted in a corresponding demand for French preachers, while Dutch authorities offered financial support. Yet a surplus of ministers also meant fierce competition over positions. The careers of Jean and Isaac Claude show that on this highly competitive market Huguenot ministers succeeded in gaining a position in the Dutch Republic by virtue of their reputation, networks, and religious and political ideas.

  20. The Newtonian Moment - Isaac Newton and the Making of Modern Culture (United States)

    Feingold, Mordechai


    Isaac Newton is a legendary figure whose mythical dimension threatens to overshadow the actual man. The story of the apple falling from the tree may or may not be true, but Isaac Newton's revolutionary discoveries and their importance to the Enlightenment era and beyond are undeniable. The Newtonian Moment , a companion volume to a forthcoming exhibition by the New York Public Library, investigates the effect that Newton's theories and discoveries had, not only on the growth of science, but also on the very shape of modern culture and thought. Newton's scientific work at Cambridge was groundbreaking. From his optical experiments with prisms during the 1660s to the publication of both Principia (1687) and Opticks (1704), Newton's achievements were widely disseminated, inciting tremendous interest and excitement. Newtonianism developed into a worldview marked by many tensions: between modernity and the old guard, between the humanities and science, and the public battles between great minds. The Newtonian Moment illuminates the many facets of his colossal accomplishments, as well as the debates over the kind of knowledge that his accomplishments engendered. The book contributes to a greater understanding of the world today by offering a panoramic view of the profound impact of Newtonianism on the science, literature, art, and religion of the Enlightenment. Copiously illustrated with items drawn from the collections of the New York Public Library as well as numerous other libraries and museums, The Newtonian Moment enlightens its audience with a guided and in-depth look at the man, his world, and his enduring legacy.

  1. Respiratory effects in children from passive smoking of cigarettes and narghile: ISAAC Phase Three in Syria. (United States)

    Mohammad, Y; Shaaban, R; Hassan, M; Yassine, F; Mohammad, S; Tessier, J F; Ellwood, P


    The association between environmental tobacco smoke (ETS) and asthma symptoms is well documented, but a causal relationship is inconclusive. International Study of Asthma and Allergies in Childhood (ISAAC) Phase Three was the first to report a dose-response relationship between current wheezing and exposure to parental cigarette smoke. As exposure of children to water pipe (narghile) smoke is of concern in Syria, in the ISAAC Phase Three Tartous Centre we also examined the role of parental smoking of the narghile. Parents of children aged 6-7 years completed core written questionnaires about the prevalence of symptoms, and an environmental questionnaire for other risk factors, including parental cigarette smoking. We added questions about narghile to the questionnaire. Among 2 734 pupils (49% females) surveyed, we found an association between exposure to ETS of the mother smoking cigarette or narghile and ever wheezing, nocturnal cough and severe wheeze; however, the strongest association was found when the mother smoked narghile. Mother smoking narghile was also associated with exercise wheeze. Father smoking narghile, but not cigarettes, was associated with nocturnal cough, severe wheeze and exercise wheeze. The association with current wheeze became significant when mother smoked both cigarettes and narghile; however, the effect was addititive and not synergic. We recommend that international studies investigating ETS include questions on narghile smoking.

  2. Leveraging Social Media Data to Understand Disaster Resilience: A Case Study of Hurricane Isaac (United States)

    Zou, L.; Lam, N.; Cai, H.


    Coastal communities are facing multiple threats from natural hazards, such as hurricanes, flooding, and storm surge, and show uneven response and recovery behaviors. To build a sustainable coast, it is critical to understand how coastal hazards affect humans and how to enhance disaster resilience. However, understanding community resilience remains challenging, due to the lack of real-time data describing community's response and recovery behaviors during disasters. Public discussion through social media platforms provides an opportunity to understand these behaviors by categorizing real-time social media data into three main phases of emergency management - preparedness, response, and recovery. This study analyzes the spatial-temporal patterns of Twitter use and content during Hurricane Isaac, which struck coastal Louisiana on August 29, 2012. The study area includes counties affected by Hurricane Isaac in Louisiana and Mississippi. The objectives are three-fold. First, we will compute a set of Twitter indices to quantify the Twitter activities during Hurricane Issac and the results will be compared with those of Hurricane Sandy to gain a better understanding of human response in extreme events. Second, county-level disaster resilience in the affected region will be computed and evaluated using the Resilience Inference Measurement (RIM) model. Third, we will examine the relationship between the geographical and social disparities in Twitter use and the disparities in disaster resilience and evaluate the role of Twitter use in disaster resilience. Knowledge gained from this study could provide valuable insights into strategies for utilizing social media data to increase resilience to disasters.

  3. I Have Faith in Thee, Lord: Criticism of Religion and Child Abuse in the Video Game the Binding of Isaac

    Directory of Open Access Journals (Sweden)

    Frank G. Bosman


    Full Text Available The game The Binding of Isaac is an excellent example of a game that incorporates criticism of religion. Isaac is a roguelike dungeon crawler with randomly generated dungeons. Both from the perspective of narrative and of game design, McMillen built The Binding of Isaac around the Biblical story of Genesis 22:1-19, which has the same name in Jewish and Christian tradition, but he placed it in a modern-day setting in which a young boy is endangered by a mentally disturbed mother who hears “voices from above” that instruct her to sacrifice her only child. Multiple critical references to Christianity can be found in addition to the narrative: hostile embodiments of the seven deadly sins, rosaries, Bibles, and crucifixes, and unlockable characters, such as Mary Magdalene, Judas Iscariot, Samson, and Cain, who are all depicted negatively in both Jewish and Christian traditions. McMillen’s inspiration came from his own experiences with his family, which was made up of both Catholics and born-again Christians. The game describes both the dark creativity and the mental and physical abuse associated with religion. In this article, we analyse the narrative of The Binding of Isaac by performing an intertextual comparison with the Biblical narrative of Genesis 22:1-19. We then analyse the three-fold narrative structure of the game which enhances and nuances the criticism the game directs at religion.

  6. Isaac Newton's scientific method turning data into evidence about gravity and cosmology

    CERN Document Server

    Harper, William L.


    Isaac Newton's Scientific Method examines Newton's argument for universal gravity and his application of it to resolve the problem of deciding between geocentric and heliocentric world systems by measuring masses of the sun and planets. William L. Harper suggests that Newton's inferences from phenomena realize an ideal of empirical success that is richer than prediction. Any theory that can achieve this rich sort of empirical success must not only be able to predict the phenomena it purports to explain, but also have those phenomena accurately measure the parameters which explain them. Harper explores the ways in which Newton's method aims to turn theoretical questions into ones which can be answered empirically by measurement from phenomena, and to establish that propositions inferred from phenomena are provisionally accepted as guides to further research. This methodology, guided by its rich ideal of empirical success, supports a conception of scientific progress that does not require construing it as progr...

  7. Newton's gift how Sir Isaac Newton unlocked the system of the world

    CERN Document Server

    Berlinski, David


    Sir Isaac Newton, creator of the first and perhaps most important scientific theory, is a giant of the scientific era. Despite this, he has remained inaccessible to most modern readers, indisputably great but undeniably remote. In this witty, engaging, and often moving examination of Newton's life, David Berlinski recovers the man behind the mathematical breakthroughs. The story carries the reader from Newton's unremarkable childhood to his awkward undergraduate days at Cambridge through the astonishing year in which, working alone, he laid the foundation for his system of the world, his Principia Mathematica, and to the subsequent monumental feuds that poisoned his soul and wearied his supporters. An edifying appreciation of Newton's greatest accomplishment, Newton's Gift is also a touching celebration of a transcendent man.

  8. Isaac Newton learns Hebrew: Samuel Johnson's Nova cubi Hebræi tabella (United States)

    Joalland, Michael; Mandelbrote, Scott


    This article concerns the earliest evidence for Isaac Newton's use of Hebrew: a manuscript copy by Newton of part of a work intended to provide a reader of the Hebrew alphabet with the ability to identify or memorize more than 1000 words and to begin to master the conjugations of the Hebrew verb. In describing the content of this unpublished manuscript and establishing its source and original author for the first time, we suggest how and when Newton may have initially become acquainted with the language. Finally, basing our discussion in part on an examination of the reading marks that Newton left in the surviving copies of Hebrew grammars and lexicons that he owned, we will argue that his interest in Hebrew was not intended to achieve linguistic proficiency but remained limited to particular theological queries of singular concern.

  9. Observing the skies of Lisbon. Isaac de Sequeira Samuda, an estrangeirado in the Royal Society. (United States)

    Vieira, Carla Costa


    Elected in 1723, Isaac de Sequeira Samuda (1681-1729) was the first Jewish Fellow of the Royal Society. He had arrived in London just a few years earlier, escaping from the Portuguese Inquisition. Despite his past, he had no difficulty in establishing links with his country's diplomatic representatives in London. A physician and adviser on scientific subjects, he became a conduit between the emerging world of Portuguese astronomy and the British scientific community. He reported to the Royal Society on astronomical observations made in the new observatories in Lisbon and helped with the acquisition of scientific instruments and books destined for Portugal. These activities were facets of Samuda's unusual career and the diverse though often converging associations that he established until his death. As the member of a network active in the diffusion of new ideas and in the modernization of Portuguese science, Samuda can be regarded as an estrangeirado, as this term has come to be used in the modern literature.

  11. An evaluation of nodalization/decay heat/ volatile fission product release models in ISAAC code

    Energy Technology Data Exchange (ETDEWEB)

    Song, Yong Mann; Park, Soo Yong; Kim, Dong Ha


    An ISAAC computer code, which was developed for a Level-2 PSA during 1995, has developed mainly with fundamental models for CANDU-specific severe accident progression and also the accident-analyzing experiences are limited to Level-2 PSA purposes. Hence the system nodalization model, decay model and volatile fission product release model, which are known to affect fission product behavior directly or indirectly, are evaluated to both enhance understanding for basic models and accumulate accident-analyzing experiences. As a research strategy, sensitivity studies of model parameters and sensitivity coefficients are performed. According to the results from core nodalization sensitivity study, an original 3x3 nodalization (per loop) method which groups horizontal fuel channels into 12 representative channels, is evaluated to be sufficient for an optimal scheme because detailed nodalization methods have no large effect on fuel thermal-hydraulic behavior, total accident progression and fission product behavior. As ANSI/ANS standard model for decay heat prediction after reactor trip has no needs for further model evaluation due to both wide application on accident analysis codes and good comparison results with the ORIGEN code, ISAAC calculational results of decay heat are used as they are. In addition, fission product revaporization in a containment which is caused by the embedded decay heat, is demonstrated. The results for the volatile fission product release model are analyzed. In case of early release, the IDCOR model with an in-vessel Te release option shows the most conservative results and for the late release case, NUREG-0772 model shows the most conservative results. Considering both early and late release, the IDCOR model with an in-vessel Te bound option shows mitigated conservative results.

    When Isaac Newton died at 85 without a will on March 20, 1727, he left a mass of disorganized papers-upwards of 8 million words-that presented an immediate challenge to his heirs. Most of these writings, on subjects ranging from secret alchemical formulas to impassioned rejections of the Holy Trinity to notes and calculations on his core discoveries in calculus, universal gravitation, and optics, were summarily dismissed by his heirs as "not fit to be printed." Rabidly heretical, alchemically obsessed, and possibly even mad, the Newton presented in these papers threatened to undermine not just his personal reputation but the status of science itself. As a result, the private papers of the world's greatest scientist remained hidden to all but a select few for over two hundred years. In The Newton Papers, Sarah Dry divulges the story of how this secret archive finally came to light-and the complex and contradictory man it revealed. Covering a broad swath of history, Dry explores who controlled Newton's legacy, ...

    Full Text Available El presente artículo propone una lectura de la novela María, del escritor colombiano Jorge Isaacs, desde la perspectiva de texto constructor de identidad nacional en virtud de su obligatorio estudio en los procesos formativos de los ciudadanos colombianos. Se hace un rastreo de elementos como actitudes frente a los esclavos, en la época en que la esclavitud fue abolida en el país; consideraciones frente a la situación de los inmigrantes judíos y la posición que ocupa la mujer en la fundación del país, asumiéndola como pilar fundamental de la sociedad. Se llega a la conclusión de que la obra debe ser entendida a la luz del contexto histórico en el que fue escrita y deninguna manera como paradigma axiomático vigente en la actualidad.

  14. The dark side of the Scientific Revolution. The Biblical interpretation in Galileo Galilei and Isaac Newton

    Directory of Open Access Journals (Sweden)

    Francesco Fiorentino


    Full Text Available This contribution investigates a hidden and surely singular – but far from marginal – aspect of the Scientific Revolution of the 17th century, in other words the interpretation of the Holy Scriptures. First of all, this work analyzes the situation immediately before the advent of the fathers of the 17th Century Scientific Revolution like Galileo Galilei and Isaac Newton, starting from the Council of Trent. This reconstruction aims to throw light on the particular way that Galileo and Newton intended to approach the interpretation of the Holy Scriptures with respect to the main tendencies of the Catholic Reformation of biblical hermeneutics. Their way is important both in itself and in relation to the Scientific Revolution. In itself because Galileo and Newton elaborate original theories that are not entirely in agreement with the predominant views and that are decidedly no less interesting than their pure scientific theories. In relation to the Scientific Revolution because the interpretation of the Holy Scriptures is addressed in an original fashion by both Galileo and Newton, also with the intent of facilitating the spread and approval of their own scientific theories in their respective socio-cultural environments. The primacy of nature is not manifested only in contrast to and outside the book of Scriptures, but conditions the Book of Scriptures, locating it within a precise cultural perspective and religious sense that are by no means contrary to Galileo and Newton’s views.

  15. The Jewish modernist: Isaac Grünewald in Bertel Hintze’s art history

    Directory of Open Access Journals (Sweden)

    Ludwig Qvarnström


    Full Text Available In the Finland-Swedish art historian and chef curator Bertel Hintze’s art historical handbook Modern konst: 1900-talet (Modern Art: Twentieth century, published in 1930, he introduce the Swedish artist Isaac Grünewald with a racial and anti-Semitic rhetoric. In this article Hintze’s rhetoric is analyzed in relation to a widespread everyday anti-Semitism and the language used in earlier art critical discussion on Grünewald’s art. The article concludes that earlier anti-Semitic expressions, visible in the negative and nationalistically oriented criticism, have been incorporated into Hintze’s ambivalent, but basically positive, characterization of Grünewald. In doing so Hintze translocate the anti-Semitic rhetoric from a negative and disparaging criticism into ‘normal’ art history, an example of how the voice of anti-Semitism have been built into the language and structure of Swedish art historiography, even where anti-Semitism was not the object.

  16. ISAAC: A REXUS Student Experiment to Demonstrate an Ejection System with Predefined Direction (United States)

    Balmer, G.; Berquand, A.; Company-Vallet, E.; Granberg, V.; Grigore, V.; Ivchenko, N.; Kevorkov, R.; Lundkvist, E.; Olentsenko, G.; Pacheco-Labrador, J.; Tibert, G.; Yuan, Y.


    ISAAC Infrared Spectroscopy to Analyse the middle Atmosphere Composition — was a student experiment launched from SSC's Esrange Space Centre, Sweden, on 29th May 2014, on board the sounding rocket REXUS 15 in the frame of the REXUS/BEXUS programme. The main focus of the experiment was to implement an ejection system for two large Free Falling Units (FFUs) (240 mm x 80 mm) to be ejected from a spinning rocket into a predefined direction. The system design relied on a spring-based ejection system. Sun and angular rate sensors were used to control and time the ejection. The flight data includes telemetry from the Rocket Mounted Unit (RMU), received and saved during flight, as well as video footage from the GoPro camera mounted inside the RMU and recovered after the flight. The FFUs' direction, speed and spin frequency as well as the rocket spin frequency were determined by analyzing the video footage. The FFU-Rocket-Sun angles were 64.3° and 104.3°, within the required margins of 90°+45°. The FFU speeds were 3.98 mIs and 3.74 mIs, lower than the expected 5± 1 mIs. The FFUs' spin frequencies were 1 .38 Hz and 1 .60 Hz, approximately half the rocket's spin frequency. The rocket spin rate slightly changed from 3. 163 Hz before the ejection to 3.1 17 Hz after the ejection of the two FFUs. The angular rate, sun sensor data and temperature on the inside of the rocket module skin were also recorded. The experiment design and results of the data analysis are presented in this paper.

  17. Diet and Respiratory Health in Children from 11 Latin American Countries: Evidence from ISAAC Phase III. (United States)

    Cepeda, Alfonso Mario; Thawer, Sumaiyya; Boyle, Robert J; Villalba, Sara; Jaller, Rodolfo; Tapias, Elmy; Segura, Ana María; Villegas, Rodrigo; Garcia-Larsen, Vanessa


    The burden of childhood asthma and its risk factors is an important but neglected public health challenge in Latin America. We investigated the association between allergic symptoms and dietary intake in children from this region. As part of the International Study of Asthma and Allergies in Childhood (ISAAC) Phase III, questionnaire collected dietary intake was investigated in relation to risk of parental/child reported current wheeze (primary outcome) and rhino-conjunctivitis and eczema. Per-country adjusted logistic regressions were performed, and combined effect sizes were calculated with meta-analyses. 143,967 children from 11 countries had complete data. In children aged 6-7 years, current wheeze was negatively associated with higher fruit intake (adjusted odds ratio [aOR] 0.65; 95% CI 0.74, 0.97). Current rhino-conjunctivitis and eczema were statistically negatively associated with fruit intake (aOR 0.72; 95% CI 0.64, 0.82; and OR 0.64, 95% CI 0.56, 0.74, respectively). Vegetable intake was negatively associated with risk of symptoms in younger children, but these associations were attenuated in the 13-14 years old group. Fastfood/burger intake was positively associated with all three outcomes in the older children. A higher intake of fruits and vegetables was associated with a lower prevalence of allergic symptoms in Latin American children. Conversely, intake of fastfood was positively associated with a higher prevalence of wheeze in adolescents. Improved dietary habits in children might help reduce the epidemic of allergic symptoms in Latin America. Food interventions in asthmatic children are needed to evaluate the possible public health impact of a better diet on respiratory health.

  18. Interrelationships between Atopic Disorders in Children: A Meta-Analysis Based on ISAAC Questionnaires.

    David H J Pols

    Full Text Available To study the prevalence and interrelationship between asthma, allergic rhinitis and eczema using data obtained from ISAAC questionnaires.The Medline, Pubmed Publisher, EMBASE, Google Scholar and the Cochrane Controlled Clinical Trials Register databases were systematically reviewed to evaluate epidemiological data of children with atopic disorders. To study these interrelationships, a new approach was used. Risk ratios were calculated, describing the risk of having two different atopic disorders when the child is known with one disorder.Included were 31 studies, covering a large number of surveyed children (n=1,430,329 in 102 countries. The calculated worldwide prevalence for asthma, eczema and allergic rhinitis is 12.00% (95% CI: 11.99-12.00, 7.88% (95% CI: 7.88-7.89 and 12.66% (95% CI: 12.65-12.67, respectively. The observed prevalence [1.17% (95% CI: 1.17-1.17] of having all three diseases is 9.8 times higher than could be expected by chance. For children with asthma the calculated risk ratio of having the other two disorders is 5.41 (95% CI: 4.76-6.16, for children with eczema 4.24 (95% CI: 3.75-4.79, and for children with allergic rhinitis 6.20 (95% CI: 5.30-7.27. No studied confounders had a significant influence on these risk ratios.Only a minority of children suffers from all three atopic disorders, however this co-occurrence is significantly higher than could be expected by chance and supports a close relationship of these disorders in children. The data of this meta-analysis supports the hypothesis that there could be a fourth distinct group of children with all three disorders. Researchers and clinicians might need to consider these children as a separate group with distinct characteristics regarding severity, causes, treatment or prognosis.

  19. Evaluation of Agreement Between Video and Written Questionnaires for Asthma Symptoms Among Children of Tehran: ISAAC Study

    MR Masjedi


    Full Text Available Introduction: International study on asthma was conducted to study the prevalence of Asthma symptoms among 13-14 year old children using written and video questionnaires during the early 90's. The aim of the present study (ISAAC was to evaluate the agreement between the two questionnaires which were self-completed by the children. Methods: This study, which was a part of the third phase of International Study of Asthma and Allergy in Childhood (ISAAC and performed exactly similar to phase1, was performed by National Research Institute of Tuberculosis and Lung Diseases (NRITLD in two cities of Iran; Rasht and Tehran. All stages of the study were performed in accordance with ISAAC protocol. The present study discusses data related to children of Tehran. A total of 3100 school children aged 13-14 years were questioned about asthma symptoms using written and video questionnaires of ISAAC study. For statistical analysis, initially a descriptive study of the available data was performed. Thereafter, chance corrected agreement between the two questionnaires was evaluated using Cohen’s Kappa co-efficiency. Results: Of the total of 3100 children, 52.4% were male and 47.6% female, with a mean age of 13.6 years. Although the questions discussed in the two questionnaires were not exactly similar, the results of the video questionnaires showed a statistically significant lower positive response to asthma symptoms as compared to the written version. Kappa co-efficiency ranged between 0.06- 0.21 (mean=0.12, which is considered poor for all variables. Conclusion: Positive responses to having asthma symptoms were significantly higher using the written questionnaire compared to the video questionnaire. Similar to previous studies, agreement between the two was considered poor for all variables. Although factors such as language, culture, dwelling area, e.t.c. have special effects on results of these questionnaires, results indicate that the two questionnaires

  20. La politización en las lecturas canónicas: Miguel Antonio Caro, lector de Jorge Isaacs

    Carlos Arturo López Jiménez


    Full Text Available The article herein shows some conceptual features of Miguel Antonio Caro’s intellectual project and its intrinsic strengths. Furthermore, it details the type of politicization which Caro imposed on some of the work of his contemporaries politicization which, in turn, was later imposed on him-self by contemporary historiography. More to the point, I evidence how Caro, when asserting that a particular text by Jorge Isaacs (The native tribes of the Magdalena basin was scientific, immediately proceeded to politicize Isaac’s work, among other things, because he (Caro did not have the relevant arguments needed to confront Isaacs’ text in its own terms and framework. Thus, in order to dismiss Isaacs’ objections raised against the government of Nuñez, Caro places the aforementioned work by the author of María, among the texts that threatened social order by presenting it as part and parcel of positivism, empiricism, liberalism, and all other intellectual efforts based on a damaging sensualism.//Aquí muestran algunos aspectos conceptuales del proyecto intelectual de Miguel Antonio Caro y su consistencia interna. Además, preciso el tipo específico de politización que este escritor impuso sobre algunos trabajos que le fueron contemporáneos –politización de la cual el mismo Caro ha sido objeto por parte de historiografía contemporánea–. Específicamente, presento cómo Miguel Antonio Caro, al afirmar que un texto de Isaacs (Las tribus indígenas del Magdalena es científico, politiza su trabajo por la imposibilidad de atacarlo dentro de los límites argumentativos del texto de Isaacs. De esta forma, para hacer a un lado las objeciones que Isaac eleva contra el gobierno de Núñez, Caro ubica el trabajo del autor de María en el grupo de escritos que amenazan el orden social, al presentarlo de la mano con el positivismo, empirismo, liberalismo y demás esfuerzos intelectuales fundados en un “nocivo” criterio sensualista.

Asimismo, se recoge información sobre la repercusión social que tuvieron dichas actuaciones en la ciudad, se describe la forma en que sus ciudadanos acogieron al artista (que permaneció en Valencia durante, al menos, veintiún días y se analizan las relaciones que estableció con algunos artistas valencianos de la época, músicos, pintores y escultores jóvenes como él, que después lograron alcanzar cierta celebridad en ámbito nacional e incluso internacional.

  2. Science fiction by scientists an anthology of short stories

    CERN Document Server


    This anthology contains fourteen intriguing short stories by active research scientists and other writers trained in science. Science is at the heart of real science fiction, which is more than just westerns with ray guns or fantasy with spaceships. The people who do science and love science best are scientists. Scientists like Isaac Asimov, Arthur C. Clarke, and Fred Hoyle wrote some of the legendary tales of golden age science fiction. Today there is a new generation of scientists writing science fiction informed with the expertise of their fields, from astrophysics to computer science, biochemistry to rocket science, quantum physics to genetics, speculating about what is possible in our universe. Here lies the sense of wonder only science can deliver. All the stories in this volume are supplemented by afterwords commenting on the science underlying each story.

  3. Charles Edward Isaacs (1811-1860): exploring the details of nephron structure and function in the post-Bowman period. (United States)

    Fine, Leon G


    Charles Edward Isaacs (1811-1860), an anatomist working in New York, undertook a series of studies which attempted to define the microscopic structure of the nephrons in a variety of species. Given that he published his findings 15 years after William Bowman's seminal paper on the subject, he was able to add only a few of the finer details to the picture. He observed the continuity of the epithelium of the glomerular capsule with that of the proximal tubule and he demonstrated that the glomerular tuft is covered by a layer of epithelial cells. In a series of studies on human renal function he erroneously concluded that the glomerulus must have an excretory function in addition to its filtration function and that diuretics act primarily on the glomerlus. The latter conclusion was based upon observations of substances not currently categorized as being diuretic agents. The absence of a major conceptual advance in the writings of Isaacs probably accounts for that fact that his contribution has been largely forgotten.

  4. Development of Isaacs' syndrome following complete recovery of voltage-gated potassium channel antibody-associated limbic encephalitis. (United States)

    Takahashi, Hirokatsu; Mori, Masahiro; Sekiguchi, Yukari; Misawa, Sonoko; Sawai, Setsu; Hattori, Takamichi; Kuwabara, Satoshi


    Autoantibodies against voltage-gated potassium channels (VGKC-Abs) are associated with acquired neuromyotonia (Isaacs' syndrome) and related disorders such as Morvan's syndrome and some cases of limbic encephalitis. The mechanisms underlying the various phenotypes induced by VGKC-Abs are not fully understood. Recently, we reported a case of LE with VGKC-Abs accompanied by severe intestinal pseudo-obstruction and thymoma. Thymectomy and immunosuppressive therapy induced dramatic clinical improvement of LE symptoms, and VGKC-Abs titers decreased from 1254 pM to 549 pM (normal>100 pM). Seventeen months later, the patient developed progressive generalized muscle cramping, paresthesias in his lower extremities, excessive sweating, and severe constipation. There was no recurrence of the LE. Electromyography showed fasciculation potentials and myokymic discharges, and the plasma VGKC-Abs titer was again elevated to 879 pM. Here we report a case of Isaacs' syndrome after complete remission of LE with VGKC-Abs that may provide an insight into a possible link among VGKC-Abs associated syndromes.

  5. There is grandeur in this view of Newton: Charles Darwin, Isaac Newton and Victorian conceptions of scientific virtue. (United States)

    Bellon, Richard


    For Victorian men of science, the scientific revolution of the seventeenth century represented a moral awakening. Great theoretical triumphs of inductive science flowed directly from a philosophical spirit that embraced the virtues of self-discipline, courage, patience and humility. Isaac Newton exemplified this union of moral and intellectual excellence. This, at least, was the story crafted by scientific leaders like David Brewster, Thomas Chalmers, John Herschel, Adam Sedgwick and William Whewell. Not everyone accepted this reading of history. Evangelicals who decried the 'materialism' of mainstream science assigned a different meaning to Newton's legacy on behalf of their 'scriptural' alternative. High-church critics of science like John Henry Newman, on the other hand, denied that Newton's secular achievements carried any moral significance at all. These debates over Newtonian standards of philosophical behavior had a decisive influence on Charles Darwin as he developed his theory of evolution by natural selection.

  6. Enlarging the bounds of moral philosophy: Why did Isaac Newton conclude the Opticks the way he did? (United States)

    Henry, John


    This paper draws attention to the remarkable closing words of Isaac Newton's Optice (1706) and subsequent editions of the Opticks (1718, 1721), and tries to suggest why Newton chose to conclude his book with a puzzling allusion to his own unpublished conclusions about the history of religion. Newton suggests in this concluding passage that the bounds of moral philosophy will be enlarged as natural philosophy is ‘perfected’. Asking what Newton might have had in mind, the paper first considers the idea that he was foreshadowing the ‘moral Newtonianism’ developed later in the eighteenth century; then it considers the idea that he was perhaps pointing to developments in natural theology. Finally, the paper suggests that Newton wanted to at least signal the importance of attempting to recover the true original religion, and perhaps was hinting at his intention to publish his own extensive research on the history of the Church.

  8. A new model of wheezing severity in young children using the validated ISAAC wheezing module: A latent variable approach with validation in independent cohorts. (United States)

    Brunwasser, Steven M; Gebretsadik, Tebeb; Gold, Diane R; Turi, Kedir N; Stone, Cosby A; Datta, Soma; Gern, James E; Hartert, Tina V


    The International Study of Asthma and Allergies in Children (ISAAC) Wheezing Module is commonly used to characterize pediatric asthma in epidemiological studies, including nearly all airway cohorts participating in the Environmental Influences on Child Health Outcomes (ECHO) consortium. However, there is no consensus model for operationalizing wheezing severity with this instrument in explanatory research studies. Severity is typically measured using coarsely-defined categorical variables, reducing power and potentially underestimating etiological associations. More precise measurement approaches could improve testing of etiological theories of wheezing illness. We evaluated a continuous latent variable model of pediatric wheezing severity based on four ISAAC Wheezing Module items. Analyses included subgroups of children from three independent cohorts whose parents reported past wheezing: infants ages 0-2 in the INSPIRE birth cohort study (Cohort 1; n = 657), 6-7-year-old North American children from Phase One of the ISAAC study (Cohort 2; n = 2,765), and 5-6-year-old children in the EHAAS birth cohort study (Cohort 3; n = 102). Models were estimated using structural equation modeling. In all cohorts, covariance patterns implied by the latent variable model were consistent with the observed data, as indicated by non-significant χ2 goodness of fit tests (no evidence of model misspecification). Cohort 1 analyses showed that the latent factor structure was stable across time points and child sexes. In both cohorts 1 and 3, the latent wheezing severity variable was prospectively associated with wheeze-related clinical outcomes, including physician asthma diagnosis, acute corticosteroid use, and wheeze-related outpatient medical visits when adjusting for confounders. We developed an easily applicable continuous latent variable model of pediatric wheezing severity based on items from the well-validated ISAAC Wheezing Module. This model prospectively associates with

  9. [Principles of order in the color systems of the 17th century. (Franciscus Aguilonius--Athanasius Kircher--Isaac Newton)]. (United States)

    Jaeger, W


    Since Aristotle there have been two colour order systems: The first is according to the subjective luminosity of colours, and the second is that which is found in the rainbow. Almost all the medieval concepts of colour order were based on the subjective luminosity of colours. At the beginning of the 17th century Franciscus Aguilonius still described the traditional sequence according to subjective luminosity: white, yellow, red, blue and black in his colour order system. - Athanasius Kircher demonstrated two sequences: The first was the same as Aguilonius 's, completed by lists of symbolic qualities attributed to the respective colours; The second was the sequence of the prismatic spectrum; red, orange, yellow, green and blue. Violet was still missing from his spectrum. For that reason the idea of arranging the colours in a closed circle did not occur to him. - Isaac Newton added violet to the prismatic spectrum. Hence he was able to bring the ends of the spectrum together, forming a colour circle. He completed the colours of his spectrum "with those purple hues which, although not present in the spectrum, were familiar to painters and dyers , and in this way closed up the colour-circle into a band returning on itself" (W. Ostwald). Thus he combined the perceptual concept of the colour wheel, containing pairs of complementary colours, with the physical concept of the prismatic spectrum.

  10. Raman spectroscopic analyses of preserved historical specimens of human hair attributed to Robert Stephenson and Sir Isaac Newton. (United States)

    Edwards, Howell G M; Hassan, Nik F N; Wilson, Andrew S


    The Raman spectra of two historical specimens of human hair attributed to the engineer Robert Stephenson and scientist Sir Isaac Newton, preserved in private collections are reported. Comparisons are made with the Raman spectra of modern hair specimens and with hair from archaeological excavations. The hair spectra collected with a laser excitation of 785 nm are of a better quality than those collected using 1064 nm. The historical hair specimens are remarkably well-defined spectroscopically in terms of the amide I vibrational mode and the [small nu](SS), ascribed to a predominantly gauche-gauche-gauche CSSC conformation. The contrast with degraded hair specimens recovered from archaeological excavations is striking. The presence of a weak feature near 2590 cm(-1) in the hair samples attributed to a [small nu](SH) vibration could be indicative of a reduction process operative on the CSSC cystine keratotic linkages and a possible origin of this is bacterial biodegradation identified histologically. This study demonstrates the molecular information available from non-destructive Raman spectroscopic analysis from single hair shafts or small bundles of fibres which complements information available from histological and destructive analytical techniques for rare biological specimens subjected to conservation or curation procedures in museums or private collections.

  11. Prevalence of asthma symptoms in Latin America: the International Study of Asthma and Allergies in Childhood (ISAAC). (United States)

    Mallol, J; Solé, D; Asher, I; Clayton, T; Stein, R; Soto-Quiroz, M


    The prevalence of respiratory symptoms indicative of asthma in children from Latin America has been largely ignored. As part of the International Study of Asthma and Allergies in Childhood (ISAAC), 17 centers in 9 different Latin American countries participated in the study, and data from 52,549 written questionnaires (WQ) in children aged 13-14 years and from 36,264 WQ in 6-7 year olds are described here. In children aged 13-14 years, the prevalence of asthma ever ranged from 5.5-28%, and the prevalence of wheezing in the last 12 months from 6.6-27%. In children aged 6-7 years, the prevalence of asthma ever ranged from 4.1-26.9%, and the prevalence of wheezing in the last 12 months ranged from 8.6-32.1%. The lower prevalence in centers with higher levels of atmospheric pollution suggests that chronic inhalation of polluted air in children does not contribute to asthma. Furthermore, the high figures for asthma in a region with a high level of gastrointestinal parasite infestation, and a high burden of acute respiratory infections occurring early in life, suggest that these factors, considered as protective in other regions, do not have the same effect in this region. The present study indicates that the prevalence of asthma and related symptoms in Latin America is as high and variable as described in industrialized or developed regions of the world.

  12. A computer simulation of iron corrosion in a sodium loop using the Fleitman-Isaacs' solubility relationship

    International Nuclear Information System (INIS)

    Polley, M.V.; Skyrme, G.


    At the present time, no theoretical treatment of mass transfer in sodium loops has been able to reconcile the low observed corrosion rates with values of iron solubility recommended in the literature. Although measured values of the solubility of iron in sodium have varied very widely, one recent determination by Fleitman and Isaacs gave low values at low oxygen activities. These values were used in the present work for predicting, by conventional mass transfer theory, corrosion in a non-isothermal loop. The method was to simulate mass transfer using a computer program while following the sodium around the loop until equilibrium was established. The advantages of this method are that the concentration driving force is predicted for all parts of the loop and that changes in mass transfer rates with change in temperature distribution and geometry can be easily investigated. The predicted variation of corrosion rate in the hot isothermal region is reported as a function of sodium velocity, downstream position, temperature, temperature differential, oxygen concentration and loop geometry. Both surface controlled and diffusion controlled mass transfer were investigated and the results were compared with the data of Thorley and Tyzack reported in the literature. (author)

    We present deep near-infrared (NIR) Js-, H-, and Ks-band ISAAC imaging of the Wide Field Planetary Camera 2 (WFPC2) field of the Hubble Deep Field South (HDF-S). The 2.5‧×2.5‧ high Galactic latitude field was observed with the Very Large Telescope under the best seeing conditions, with integration times amounting to 33.6 hr in Js, 32.3 hr in H, and 35.6 hr in Ks. We reach total AB magnitudes for point sources of 26.8, 26.2, and 26.2, respectively (3 σ), which make it the deepest ground-based NIR observation to date and the deepest Ks-band data in any field. The effective seeing of the co-added images is ~0.45" in Js, ~0.48" in H, and ~0.46" in Ks. Using published WFPC2 optical data, we constructed a Ks-limited multicolor catalog containing 833 sources down to Ktots,AB2.3 (in Johnson magnitudes). Because they are extremely faint in the observed optical, they would be missed by ultraviolet-optical selection techniques, such as the U-dropout method. Based on service mode observations collected at the European Southern Observatory, Paranal, Chile (ESO Program 164.O-0612). Also based on observations with the NASA/ESA Hubble Space Telescope, obtained at the Space Telescope Science Institute, which is operated by the Association of Universities for Research in Astronomy (AURA), Inc., under NASA contract NAS 5-26555.

  14. Prevalence of symptoms of eczema in Latin America: results of the International Study of Asthma and Allergies in Childhood (ISAAC) Phase 3. (United States)

    Solé, D; Mallol, J; Wandalsen, G F; Aguirre, V


    The aim of the International Study of Asthma and Allergies in Childhood (ISAAC) was to evaluate the prevalence of symptoms of eczema among children living in different parts of Latin America. Data were from centers that participated in ISAAC Phase 3. This was a cross-sectional questionnaire survey of 93,851 schoolchildren (6 to 7 years old) from 35 centers in 14 Latin American countries and 165,917 adolescents (13 to 14 years old) from 56 centers in 17 Latin American countries. The mean prevalence of current flexural eczema in schoolchildren was 11.3%, ranging from 3.2% in Ciudad Victoria (Mexico) to 25.0% in Barranquilla (Colombia). For adolescents, the prevalence varied from 3.4% in Santo André (Brazil) to 30.2% in Barranquilla (mean prevalence, 10.6%). The mean prevalence of current symptoms of severe eczema among schoolchildren was 1.5%, ranging from 0.3% in Ciudad Victoria, Toluca, and Cuernavaca (Mexico) to 4.9% in La Habana (Cuba). For adolescents, the mean prevalence was 1.4%, ranging from 0.1% in Mexicali Valley (Mexico) to 4.2% in Santa Cruz (Bolivia). These prevalence values are among the highest observed during ISAAC Phase 3. In general, the prevalence of current symptoms of eczema was higher among the Spanish-speaking centers for both schoolchildren and adolescents. Environmental risk factors must be evaluated in order to identify potential causes for the differences observed, even in centers from the same country.

    Full Text Available This paper aimed to analyze the argumentative structure and the characteristics of arguments used in Isaac Newton’s paper where his “New theory about light and colors”, written in 1672, is described. For this purpose, we have used “Toulmin’s Argument Pattern” as an analytical tool. The identification of argumentative structure in a scientific text can help one to understand the argument construction in science and support this reasoning on science education, particularly on textbooks organization. This analysis has characterized the arguments presented in the text and shown its relation to Newton’s explanation on color in light refraction phenomenon through a prism.

    Full Text Available This special section examines Isaac Wetzlar‘s Love Letter, a Yiddish proposal for the improvement of Jewish society, written in 1748/49 in Northern Germany. The articles concentrate on the links between Libes briv and the contours of German Pietism in order to initiate exploration of the complex relationship between Central European Judaism and eighteenth-century Pietism. This largely unrecognized arena of Jewish-Christian encounter is presented as a significant factor in a century that promoted modernity

  18. Some attempts at a geological explanation for the origin of the Sierra Nevada de Santa Marta in the Nineteenth Century: the naturalists Joaquin Acosta and Jorge Isaacs

    International Nuclear Information System (INIS)

    Castro Lopez, Pablo Antonio; Cardona Molina, Agustin


    The Sierra Nevada de Santa Marta, located in the northernmost part of Colombia, has been an object of scientific inquiry since at least the XIXth century, among other things because of its isolated character in relation to the Andean mountain chain. In this article we present some contributions to the knowledge of its origin and geological framework made by Joaquin Acosta (1800-1852) and Jorge Isaacs (1837-1895). Furthermore we establish a possible theoretical and conceptual relationship between these authors and some important European geologists and naturalists in the XIXth century, in the context of a history of ideas pertaining to orogenesis in Colombia.

  19. The Secrets of the Nearest Starburst Cluster. I. Very Large Telescope/ISAAC Photometry of NGC 3603 (United States)

    Stolte, Andrea; Brandner, Wolfgang; Brandl, Bernhard; Zinnecker, Hans; Grebel, Eva K.


    VLT/ISAAC JHKL photometry with subarcsecond resolution of the dense, massive starburst cluster NGC 3603 YC forming the core of the NGC 3603 giant molecular cloud is analyzed to reveal characteristics of the stellar population in unprecedented detail. The color-magnitude plane features a strong pre-main-sequence/main-sequence (PMS/MS) transition region, including the PMS/MS transition point, and reveals a secondary sequence for the first time in a nearby young starburst cluster. Arguments for a possible binary nature of this sequence are given. The resolved PMS/MS transition region allows isochrone fitting below the hydrogen-burning turn-on in NGC 3603 YC, yielding an independent estimate of global cluster parameters. A distance modulus of 13.9 mag, equivalent to d=6.0+/-0.3 kpc, is derived, as well as a line-of-sight extinction of AV=4.5+/-0.6 toward PMS stars in the cluster center. The interpretation of a binary candidate sequence suggests a single age of 1 Myr for NGC 3603 YC, providing evidence for a single burst of star formation without the need to employ an age spread in the PMS population, as argued for in earlier studies. Disk fractions are derived from L-band excesses, indicating a radial increase in the disk frequency from 20% to 40% from the core to the cluster outskirts. The low disk fraction in the cluster core, as compared to the 42% L-band excess fraction found for massive stars in the Trapezium cluster of a comparably young age, indicates strong photoevaporation in the cluster center. The estimated binary fraction of 30%, as well as the low disk fraction, suggest strong impacts on low-mass star formation due to stellar interactions in the dense starburst. The significant differences between NGC 3603 YC and less dense and massive young star clusters in the Milky Way reveal the importance of using local starbursts as templates for massive extragalactic star formation.

    Context. One-opposition near-Earth asteroids (NEAs) are growing in number, and they must be recovered to prevent loss and mismatch risk, and to improve their orbits, as they are likely to be too faint for detection in shallow surveys at future apparitions. Aims: We aimed to recover more than half of the one-opposition NEAs recommended for observations by the Minor Planet Center (MPC) using the Isaac Newton Telescope (INT) in soft-override mode and some fractions of available D-nights. During about 130 h in total between 2013 and 2016, we targeted 368 NEAs, among which 56 potentially hazardous asteroids (PHAs), observing 437 INT Wide Field Camera (WFC) fields and recovering 280 NEAs (76% of all targets). Methods: Engaging a core team of about ten students and amateurs, we used the THELI, Astrometrica, and the Find_Orb software to identify all moving objects using the blink and track-and-stack method for the faintest targets and plotting the positional uncertainty ellipse from NEODyS. Results: Most targets and recovered objects had apparent magnitudes centered around V 22.8 mag, with some becoming as faint as V 24 mag. One hundred and three objects (representing 28% of all targets) were recovered by EURONEAR alone by Aug. 2017. Orbital arcs were prolonged typically from a few weeks to a few years; our oldest recoveries reach 16 years. The O-C residuals for our 1854 NEA astrometric positions show that most measurements cluster closely around the origin. In addition to the recovered NEAs, 22 000 positions of about 3500 known minor planets and another 10 000 observations of about 1500 unknown objects (mostly main-belt objects) were promptly reported to the MPC by our team. Four new NEAs were discovered serendipitously in the analyzed fields and were promptly secured with the INT and other telescopes, while two more NEAs were lost due to extremely fast motion and lack of rapid follow-up time. They increase the counting to nine NEAs discovered by the EURONEAR in 2014 and

  1. Prevalence of rhinitis-related symptoms in Latin American children - results of the International Study of Asthma and Allergies in Childhood (ISAAC) phase three. (United States)

    Solé, Dirceu; Mallol, Javier; Camelo-Nunes, Inês C; Wandalsen, Gustavo F


    The aim of this study was to evaluate the prevalence of rhinitis-related symptoms among children living in different parts of Latin America (LA) considering all centers involved in ISAAC Phase Three (Ph3). 93,851 children (6-7 yr-old) from 35 centers in 14 LA countries and 165,917 adolescents (13-14 yr-old) from 56 centers in 17 LA countries were enrolled. The mean prevalence rate of current rhinoconjunctivitis was 12.7% and ranged from 5.5% in Rosario City (Argentina) to 21.2% in Caracas (Venezuela) for the schoolchildren. The mean prevalence rate of current rhinoconjunctivitis was 18.5% and ranged from 7.1% in Cuernavaca (México) to 45.1% in Asunción (Paraguay) for the adolescents. These indexes were among the higher observed during ISAAC Ph3. In general the prevalence of rhinitis-related symptoms was higher among the Spanish speaking centers. Environmental risk factors must be evaluated in order to explain the differences observed even in centers from the same country. © 2009 John Wiley & Sons A/S.

    The objective of this study was to estimate the relationship between the prevalence of asthma in schoolchildren aged 6-7 years and 13-14 years and the mean annual sunny hours (MASH) in Spain, and to explore predictive models for asthma prevalence. The prevalence of asthma was obtained from the International Study of Asthma and Allergies (ISAAC) Phase III 2002-2003, and climate and socio-economic variables from official sources. Nine centres were studied and a further four centres, two of which are in ISAAC, to test the predictive models. Logistic regression was used to estimate adjusted prevalence rates of asthma for each centre, and multiple regression models to study the effects of MASH and other meteorological and socio-economic variables. The adjusted prevalence rate of asthma decreased 0.6% [95% confidence interval (CI) 0.4-0.8%] for the 6-7 years group and 1.1% (95% CI 0.8-1.3%) for the 13-14 years group with an increase in the MASH of 100 h. Relative humidity was negatively associated with asthma in the older age group, and gross province product per capita (GPP) was positively associated with asthma in the younger age group. The predictive models, which included MASH, gender, relative humidity, and GPP, anticipated prevalence rates of asthma without significant differences between the levels observed and those expected in 9 of the11 measurements carried out. The results indicate that sunny hours have a protective effect on the prevalence of asthma in schoolchildren.

  8. The role of Dr Isaac Aaron and the Australian Medical Journal in the dissemination of information about etherisation in the 1840s. (United States)

    Paull, J D


    Isaac Aaron (1804 to 1877), an ambitious young medical practitioner, arrived in Sydney from Britain in 1838 and was registered by the New South Wales Medical Board the following year. After contributing to the Australian Medical Journal, established in August 1846 by William Baker, he became the editor in December and acquired it in May the following year. Dr Pugh became the most prolific local contributor to the journal but he and the editor had a somewhat 'prickly' relationship. Aaron was very critical of etherisation when the first news arrived in Australia, but Pugh chose Aaron's journal in which to report his initial and subsequent experience with the technique. Aaron repeatedly appealed for experimental evidence and rational decision-making to determine the place of etherisation in medical practice. Unfortunately for Australian medicine, Aaron had to suspend the publication of the journal in October 1847, lacking both time and the support of the profession necessary to maintain it. This created an unanticipated adverse outcome for Dr Pugh.

  9. Cooking fuels and prevalence of asthma: a global analysis of phase three of the International Study of Asthma and Allergies in Childhood (ISAAC). (United States)

    Indoor air pollution from a range of household cooking fuels has been implicated in the development and exacerbation of respiratory diseases. In both rich and poor countries, the effects of cooking fuels on asthma and allergies in childhood are unclear. We investigated the association between asthma and the use of a range of cooking fuels around the world. For phase three of the International Study of Asthma and Allergies in Childhood (ISAAC), written questionnaires were self-completed at school by secondary school students aged 13-14 years, 244,734 (78%) of whom were then shown a video questionnaire on wheezing symptoms. Parents of children aged 6-7 years completed the written questionnaire at home. We investigated the association between types of cooking fuels and symptoms of asthma using logistic regression. Adjustments were made for sex, region of the world, language, gross national income, maternal education, parental smoking, and six other subject-specific covariates. The ISAAC study is now closed, but researchers can continue to use the instruments for further research. Data were collected between 1999 and 2004. 512,707 primary and secondary school children from 108 centres in 47 countries were included in the analysis. The use of an open fire for cooking was associated with an increased risk of symptoms of asthma and reported asthma in both children aged 6-7 years (odds ratio [OR] for wheeze in the past year, 1·78, 95% CI 1·51-2·10) and those aged 13-14 years (OR 1·20, 95% CI 1·06-1·37). In the final multivariate analyses, ORs for wheeze in the past year and the use of solely an open fire for cooking were 2·17 (95% CI 1·64-2·87) for children aged 6-7 years and 1·35 (1·11-1·64) for children aged 13-14 years. Odds ratios for wheeze in the past year and the use of open fire in combination with other fuels for cooking were 1·51 (1·25-1·81 for children aged 6-7 years and 1·35 (1·15-1·58) for those aged 13-14 years. In both age groups, we

  10. Antibiotic sales and the prevalence of symptoms of asthma, rhinitis, and eczema: The International Study of Asthma and Allergies in Childhood (ISAAC). (United States)

    It has been hypothesized that antibiotic use early in life may increase the subsequent risk of asthma. We have conducted an ecologic analysis of the relationship between antibiotics sales and the prevalence of symptoms of asthma, allergic rhinoconjunctivitis, and atopic eczema in 99 centres from 28 countries. Data for antibiotics sales for 28 countries were obtained from the Institute for Medical Statistics (IMS), Health Global Services, UK and converted to defined daily doses (DDD). Data on the prevalence of symptoms of asthma, rhinitis, and eczema in 13-14 year olds were based on the responses to the written and video questionnaires from the International Study of Asthma and Allergies in Childhood (ISAAC). The analysis was adjusted for gross national product (GNP) as an estimate of the level of affluence. In general, there was a positive association between per capita antibiotics sales and the prevalence of symptoms for asthma, rhinitis, and eczema, but the associations generally became negative once the analyses had been adjusted for GNP. In particular, there were non-significant negative associations between total antibiotics sales and the prevalence of wheeze ever, wheeze in the last 12 months, nose problems with itchy-watery eyes, itchy rash in the last 12 months, and eczema ever. On the other hand there were weak non-significant positive associations for asthma ever, nose problems ever, nose problems in the last 12 months, and itchy rash ever. There was a statistically significant positive association with wheeze at rest as measured by the asthma video questionnaire; however, even this association was weak and would not account for more than a 1% difference in asthma prevalence between countries. These findings are generally not consistent with the hypothesis that antibiotic use increases the risk of asthma, rhinitis, or eczema. If there is a causal association of antibiotic use with asthma risk, it does not appear to explain the international differences in

    Phase One of the International Study of Asthma and Allergies in Childhood (ISAAC) measured the global patterns of prevalence and severity of symptoms of rhinoconjunctivitis in children in 1993-1997. International Study of Asthma and Allergies in Childhood Phase Three was a cross-sectional survey performed 5-10 years after Phase One using the same methodology. Phase Three covered all of the major regions of the world and involved 1 059 053 children of 2 age groups from 236 centres in 98 countries. The average overall prevalence of current rhinoconjunctivitis symptoms was 14.6% for the 13- to 14-year old children (range 1.0-45%). Variation in the prevalence of severe rhinoconjunctivitis symptoms was observed between centres (range 0.0-5.1%) and regions (range 0.4% in western Europe to 2.3% in Africa), with the highest prevalence being observed mainly in the centres from middle and low income countries, particularly in Africa and Latin America. Co-morbidity with asthma and eczema varied from 1.6% in the Indian sub-continent to 4.7% in North America. For 6- to 7-year old children, the average prevalence of rhinoconjunctivitis symptoms was 8.5%, and large variations in symptom prevalence were also observed between regions, countries and centres. Wide global variations exist in the prevalence of current rhinoconjunctivitis symptoms, being higher in high vs low income countries, but the prevalence of severe symptoms was greater in less affluent countries. Co-morbidity with asthma is high particularly in Africa, North America and Oceania. This global map of symptom prevalence is of clinical importance for health professionals.

    Morgan, Karen L. M.; Karen A. Westphal,


    The U.S. Geological Survey (USGS), as part of the National Assessment of Coastal Change Hazards project, conducts baseline and storm-response photography missions to document and understand the changes in vulnerability of the Nation's coasts to extreme storms (Morgan, 2009). On September 2-3, 2012, the USGS conducted an oblique aerial photographic survey along the Alabama, Mississippi, and Louisiana barrier islands aboard a Cessna 172 (aircraft) at an altitude of 500 feet (ft) and approximately 1,000 ft offshore. This mission was flown to collect post-Hurricane Isaac data for assessing incremental changes in the beach and nearshore area since the last survey, flown in September 2008 (central Louisiana barrier islands) and June 2011 (Dauphin Island, Alabama, to Breton Island, Louisiana), and the data can be used in the assessment of future coastal change.The photographs provided in this report are Joint Photographic Experts Group (JPEG) images. ExifTool was used to add the following to the header of each photo: time of collection, Global Positioning System (GPS) latitude, GPS longitude, keywords, credit, artist (photographer), caption, copyright, and contact information. The photograph locations are an estimate of the position of the aircraft at the time the photograph was taken and do not indicate the location of any feature in the images (see the Navigation Data page). These photographs document the state of the barrier islands and other coastal features at the time of the survey. Pages containing thumbnail images of the photographs, referred to as contact sheets, were created in 5-minute segments of flight time. These segments can be found on the Photos and Maps page. Photographs can be opened directly with any JPEG-compatible image viewer by clicking on a thumbnail on the contact sheet.In addition to the photographs, a Google Earth Keyhole Markup Language (KML) file is provided and can be used to view the images by clicking on the marker and then clicking on

  16. Who wrote the rules for the Trans-Pacific Partnership?

    Directory of Open Access Journals (Sweden)

    Todd Allee


    Full Text Available Twelve governments recently signed the much-anticipated Trans-Pacific Partnership (TPP, sparking heated debate about its merits. As a primary motivation for this first “mega-regional” agreement, US President Barack Obama argues that the TPP is a way for the USA, and not China or someone else, to write the global trade rules of the future. This begs some important questions, namely which country or countries really did write most of the TPP and thus whose agenda for 21st century trade might it advance? To answer these questions, we compare the recently-released text of the TPP to the language in the 74 previous trade agreements that TPP members signed since 1995. Our text-as-data analyses reveal that the contents of the TPP are taken disproportionately from earlier US trade agreements. The ten preferential trade agreements (PTAs that most closely match the TPP are all US PTAs. Moreover, the contents of controversial chapters, such as the one on investment, are drawn even more heavily from past US treaty language. Our study and findings apply power-based accounts of international institutions to a landmark new agreement, and portray a more active, template-based process of international diffusion.

  17. Girl who wrote to primo levi. The "foreign body" speaks. (United States)

    Ceragioli, Giuditta


    Through the exposition of a clinical case, the author explores how a sexually abused woman can set up strategies for psychic survival to the feeling of catastrophe and how she can attempt to communicate and share it. The clinical case connects childhood sexual abuse trauma and the trauma of surviving concentration camps. The paper refers to two main achievements of Ferenczi's research: (1) the consequences of the traumatic experience and of the disavowal of it, such as dissociation, fragmentation, psychic agony; and (2) the focus on countertransference as emotional sharing and as receptiveness to the deep, unconscious and unspeakable communications, which can transfer to the psychoanalyst through somatic ways.

    Phase I of the International Study of Asthma and Allergies in Childhood (ISAAC) was designed to allow worldwide comparisons of the prevalence of asthma symptoms. In phase III the phase I survey was repeated in order to assess changes over time. The phase I survey was repeated after an interval of 5-10 years in 106 centres in 56 countries in children aged 13-14 years (n = 304,679) and in 66 centres in 37 countries in children aged 6-7 years (n = 193,404). The mean symptom prevalence of current wheeze in the last 12 months changed slightly from 13.2% to 13.7% in the 13-14 year age group (mean increase of 0.06% per year) and from 11.1% to 11.6% in the 6-7 year age group (mean increase of 0.13% per year). There was also little change in the mean symptom prevalence of severe asthma or the symptom prevalence measured with the asthma video questionnaire. However, the time trends in asthma symptom prevalence showed different regional patterns. In Western Europe, current wheeze decreased by 0.07% per year in children aged 13-14 years but increased by 0.20% per year in children aged 6-7 years. The corresponding findings per year for the other regions in children aged 13-14 years and 6-7 years, respectively, were: Oceania (-0.39% and -0.21%); Latin America (+0.32% and +0.07%); Northern and Eastern Europe (+0.26% and +0.05%); Africa (+0.16% and +0.10%); North America (+0.12% and +0.32%); Eastern Mediterranean (-0.10% and +0.79%); Asia-Pacific (+0.07% and -0.06%); and the Indian subcontinent (+0.02% and +0.06%). There was a particularly marked reduction in current asthma symptom prevalence in English language countries (-0.51% and -0.09%). Similar patterns were observed for symptoms of severe asthma. However, the percentage of children reported to have had asthma at some time in their lives increased by 0.28% per year in the 13-14 year age group and by 0.18% per year in the 6-7 year age group. These findings indicate that international differences in asthma symptom prevalence

  20. [Changes in the prevalence of asthma in Chilean school age children between 1994 and 2002. International Study of Asthma and Allergies in Childhood (ISAAC)--Chile phases I and III]. (United States)

    Mallol, Javier; Aguirre, Viviana; Aguilar, Pedro; Calvo, Mario; Amarales, Lidia; Arellano, Pamela; Palma, Rodrigo


    In developed countries, the prevalence of asthma in children has significantly increased in the last decades. However, there is no information about the trends of asthma in Latin America. To determine changes in asthma prevalence between 1994 and 2002 in Chilean schoolchildren. The prevalence of asthma symptoms in schoolchildren aged 7 (n =18.697) and 13 years (n =18.939), from South Santiago, Valdivia and Punta Arenas, obtained during phases I and III of the ISAAC, carried out in 1994 and 2002, was compared. From 1994 to 2002, the mean national prevalence of "wheezing in the last 12 months" in the group aged 6-7 years, changed from 18.2% to 17.9% (p =NS); "asthma ever" from 12.5% to 10.7% (p =NS), and "severe episode" from 3.2% to 2.8% (p =NS). There was a significant increase of the prevalence of "wheezing in the last 12 months", in children aged 13-14 years, from 9.8% to 15.5% (p =0.01); in "asthma ever" from 10.2% to 14.9% (p =0.01), and for "severe episode" from 2.8% to 3.8% (p =0.01). There was a significant increase in the prevalence of respiratory symptoms related to asthma in children aged 13-14 years that was consistent in all the 3 participating centres of the ISAAC. However, the prevalence of asthma symptoms in children aged 6-7 years remained without significant changes between 1994 and 2002.

  1. Quality and energy yield of modules and photovoltaic plants - Final report; Qualita e resa energetica di moduli ed impianti fotovoltaici. Centrale ISAAC-TISO - Periodo VII: 2003-2006

    Energy Technology Data Exchange (ETDEWEB)

    Chianese, D; Bernasconi, A; Friesen, G; Cereghetti, N; Pola, I; Bura, E; Nagel, K; Pittet, D; Realini, A; Pasinelli, P; Ballerini, N; Rioggi, S


    This comprehensive final report for the Swiss Federal Office of Energy (SFOE) reviews work done at the ISAAC-TISO test centre in southern Switzerland. The main objective of the test centre is the evaluation of photovoltaic module quality, i.e. the assessment of the power values declared by the manufacturer, the electrical behaviour and energy production in varying climatic conditions, the stability of these values over time, and module life-span. Up till now, both outdoor and indoor structures for testing the electrical behaviour of modules have been realised. Indoor measurements under standard conditions are carried out using a solar simulator, outdoor measurements are carried out using external stands capable of accommodating 18 pairs of modules. The aim of the test procedure is to verify the actual power of modules; to verify if module guarantees are respected; to observe the behaviour of modules under real climatic conditions; to compare the energy yield of the different types of module; and finally, to develop methods for forecasting energy yield. The test installations are described in detail and various results are presented. Building-integrated photovoltaics is discussed and the mechanical characteristics of various module types are examined.

  2. Isaac Newton: Eighteenth-century Perspectives (United States)

    Hall, A. Rupert


    This new product of the ever-flourishing Newton industry seems a bit far-fetched at first sight: who but a few specialists would be interested in the historiography of Newton biography in the eighteenth century? On closer inspection, this book by one of the most important Newton scholars of our day turns out to be of interest to a wider audience as well. It contains several biographical sketches of Newton, written in the decades after his death. The two most important ones are the Eloge by the French mathematician Bernard de Fontenelle and the Italian scholar Paolo Frisi's Elogio. The latter piece was hitherto unavailable in English translation. Both articles are well-written, interesting and sometimes even entertaining. They give us new insights into the way Newton was revered throughout Europe and how not even the slightest blemish on his personality or work could be tolerated. An example is the way in which Newton's famous controversy with Leibniz is treated: Newton is without hesitation presented as the wronged party. Hall has provided very useful historical introductions to the memoirs as well as footnotes where needed. Among the other articles discussed is a well-known memoir by John Conduitt, who was married to Newton's niece. This memoir, substantial parts of which are included in this volume, has been a major source of personal information for Newton biographers up to this day. In a concluding chapter, Hall gives a very interesting overview of the later history of Newton biography, in which he describes the gradual change from adoration to a more critical approach in Newton's various biographers. In short, this is a very useful addition to the existing biographical literature on Newton. A J Kox

  7. The foundation: Mechanism, prediction, and falsification in Bayesian enactivism. Comment on "Answering Schrödinger's question: A free-energy formulation" by Maxwell James Désormeau Ramstead et al. (United States)

    Allen, Micah


    In Isaac Asimov's science fiction classic, Foundation, fictional mathematician Hari Seldon applies his theory of psychohistory, a synthesis of psychology, history, and statistical physics, to predict that humanity will suffer a dark age lasting thirty millennia [1]. Although Seldon's psychohistory successfully predicts the future of human society, its basis in the physical law of mass action carries a limitation - it can only do so for sufficiently massive populations (i.e., billions of individuals), rendering it inert at an individual level. This limitation is of course a key source of dramatic tension in the series, in which the individual characters of Asimov's universe grapple with the challenges inherent to applying a lawlike theory of collective action to the constitutive individuals. To avert crisis, Seldon ultimately assembles the namesake Foundation, an interdisciplinary, intergalactic research centre bringing together various biological, physical, and social scientists who ultimately attempt to alter the predicted course of history.

  8. 'They wrote "gay" on her file': transgender Ugandans in HIV prevention and treatment. (United States)

    Minor Peters, Melissa


    This paper examines the ways in which HIV-related programmes for heterosexual Ugandans and also for men who have sex with men work to deny healthcare services to transgender people in Uganda. Contrary to current conventional wisdom, the study found that the widespread use of the term 'men who have sex with men' produces greater barriers to healthcare for queer Ugandans than identity categories such as 'lesbian' or 'transgender'. Interventions for men who have sex with men assume a male-identified sexual subject with agency over sexual practices, such as frequency of condom use. Based on two years of ethnographic research in Kampala, I suggest that the focus on individual sexual practices harms transgender people in two ways. First, current HIV prevention and treatment programmes fail to account for risk factors that accrue to both male and female transgender Ugandans due to the social enforcement of gender norms. Second, the term men who have sex with men directs attention towards stigmatised sexual practices, producing the neglect and abuse of non-heteronormative individuals. In the context of Ugandan healthcare, terms such as 'transgender' and kuchu instead focus attention on the dignity and humanity of the rights-bearing person. These findings emphasise how health practitioners must pay attention to emic categories in order to address the ways in which vulnerability is distributed along social vectors of difference.

    This book is based on my doctoral dissertation from the Hebrew University of Jerusalem (1996) of the same title. As a master's student, working on an entirely different project, I was well aware that many of Newton's theological manuscripts were located in our own Jewish National and University Library, but I was under the mistaken assumption that scores of highly qualified scholars must be assiduously scouring them and publishing their results. It never occurred to me to look at them at all until, having fmished my master's, I spoke to Professor David Katz at Tel-Aviv University about an idea I had for doctoral research. Professor Katz informed me that the project I had suggested was one which he himself had just fmished, but that I might be interested in working on the famous Newton manuscripts in the context of a project being organized by him, Richard Popkin, James Force, and the late Betty Jo Teeter Dobbs, to study and publish Newton's theological material.

  15. Catch a falling apple: Isaac Newton and myths of genius. (United States)

    Fara, P


    Newton has become a legendary figure belonging to the distant past rather than a historical person who lived at a specific time. Historians and scientists have constantly reinterpreted many anecdotal tales describing Newton's achievements and behaviour, but the most famous concerns the falling apple in his country garden. Newton's apple conjures up multiple allegorical resonances, and examining its historical accuracy is less important than uncovering the mythical truths embedded within this symbol. Because interest groups fashion different collective versions of the past, analysing mythical tales can reveal fundamental yet conflicting attitudes towards science and its practices.

  12. Socio-economic impact of antiretroviral treatment in HIV patients. An economic review of cost savings after introduction of HAART. (United States)

    Gonzalo, Teresa; García Goñi, Manuel; Muñoz-Fernández, María Angeles


    Star celebrities such as Rock Hudson, Freddie Mercury, Magic Johnson, and Isaac Asimov have unfortunately something in common: they were all victims of the HIV global pandemic. Since then HIV infection has become considered a pandemic disease, and it is regarded as a priority in healthcare worldwide. It is ranked as the first cause of death among young people in industrialized countries, and it is recognized as a public healthcare problem due to its human, social, mass media, and economic impact. Incorporation of new and highly active antiretroviral treatment, available since 1996 for HIV/AIDS treatment, has provoked a radical change in the disease pattern, as well as in the impact on patient survival and quality of life. The pharmaceutical industry's contribution, based on the research for more active new drugs, has been pivotal. Mortality rates have decreased significantly in 20 years by 50% and now AIDS is considered a chronic and controlled disease. In this review we have studied the impact of HAART treatment on infected patients, allowing them to maintain their status as active workers and the decreased absenteeism from work derived from this, contributing ultimately to overall social wealth and, thus, to economic growth. Furthermore, an analysis of the impact on healthcare costs, quality of life per year, life per year gained, cost economic savings and cost opportunity among other parameters has shown that society and governments are gaining major benefits from the inclusion of antiretroviral therapies in HIV/AIDS patients.

  14. The Future of the New Media in the Communication of Science (United States)

    Hanson, Joseph


    New media, that which is based around social networks, ubiquitous consumer technology, and today's near-universal access to information, has transformed the way that science is communicated to the scientist and non-scientist alike. We may be in the midst of mankind's greatest shift in information consumption and distribution since the invention of the printing press. Or maybe not. The problem with predicting the future is that it's very hard, and unless you're Isaac Asimov, it's very easy to be wrong. When one predicts the future regarding the internet, that risk becomes almost a certainty. Still, we can apply lessons learned from the near and distant history of science communication to put today's new media evolution into perspective, and to give us clues as to where social media, digital journalism, open access, and online education will lead science communication in years to come. Most importantly, it remains to be seen whether this new media evolution will translate into a shift in how science is viewed by citizens and their policymakers.

  15. AIonAI: a humanitarian law of artificial intelligence and robotics. (United States)

    Ashrafian, Hutan


    The enduring progression of artificial intelligence and cybernetics offers an ever-closer possibility of rational and sentient robots. The ethics and morals deriving from this technological prospect have been considered in the philosophy of artificial intelligence, the design of automatons with roboethics and the contemplation of machine ethics through the concept of artificial moral agents. Across these categories, the robotics laws first proposed by Isaac Asimov in the twentieth century remain well-recognised and esteemed due to their specification of preventing human harm, stipulating obedience to humans and incorporating robotic self-protection. However the overwhelming predominance in the study of this field has focussed on human-robot interactions without fully considering the ethical inevitability of future artificial intelligences communicating together and has not addressed the moral nature of robot-robot interactions. A new robotic law is proposed and termed AIonAI or artificial intelligence-on-artificial intelligence. This law tackles the overlooked area where future artificial intelligences will likely interact amongst themselves, potentially leading to exploitation. As such, they would benefit from adopting a universal law of rights to recognise inherent dignity and the inalienable rights of artificial intelligences. Such a consideration can help prevent exploitation and abuse of rational and sentient beings, but would also importantly reflect on our moral code of ethics and the humanity of our civilisation.

  18. Magic Learning Pill: Ontological and Instrumental Learning in Order to Speed Up Education. (United States)

    Matusov, Eugene; Baker, Daniella; Fan, Yueyue; Choi, Hye Jung; L Hampel, Robert


    The purpose of this research is to investigate the phenomenology of learning - people"s attitudes toward their learning experiences that have inherent worth in themselves (i.e., ontological learning) or have value outside of the learning itself (i.e., instrumental learning). In order to explore this topic, 58 participants from the U.S., Russia, and Brazil were interviewed with a central question derived from the science fiction writer Isaac Asimov's short story "Profession": whether participants would take a "Magic Learning Pill" (MLP) to avoid the process of learning, and instead magically acquire the knowledge. The MLP would guarantee the immediate learning by skipping the process of learning while achieving the same effect of gaining skills and knowledge. Almost all participants could think of some learning experiences for which they would take MLP and others for which they would not. Many participants would not take MLP for ontological learning, which is learning experiences that have inherent value for the people, while they would take MLP for instrumental learning, which is learning that mainly serves some other non-educational purposes. The main finding suggests that both instrumental and ontological types of learning are recognized by a wide range of people from diverse cultures as present and valued in their lives. This is especially significant in light of the overwhelmingly instrumental tone of public discourse about education. In the context of formal education, ontological learning was mentioned 35 times (28.0%) while instrumental learning was mentioned 74 times (60.2%). Although ontological learning was often mentioned as taking place outside of school, incorporating pedagogy supporting ontological learning at school deserves consideration.

    Diets which emphasize intakes of plant-based foods are recommended to reduce disease risk and for promoting healthy weight. The aim of this study was to examine the association between fruit, vegetables, pulses and nut intake and body mass index (BMI) across countries in adolescents (13-14 years) and children (6-7 years). Data from the International Study of Asthma and Allergies in Childhood; 77,243 children's parents and 201,871 adolescents was used to examine the association between dietary intake (Food Frequency Questionnaire) and BMI using general linear models, adjusting for country gross national index. Adolescents who consumed fruit, vegetables, pulses and nuts three or more times a week had a lower BMI than the never or occasional group; eating nuts three or more times a week, was associated with a BMI value of 0.274 kg/m² lower than the never group ( p BMI of -0.079 kg/m². In this large global study, an inverse association was observed between BMI and the reported increasing intake of vegetables in 6-7 years old and fruit, vegetables, pulses and nuts in adolescents.

    Full Text Available School closures, while an effective measure against the spread of disease during a pandemic, may carry unintended social and economic consequences for students and families. We evaluated these costs and consequences following a 4-day school closure in Mississippi's Harrison County School District (HCSD.In a survey of all households with students enrolled in HCSD, we collected information on difficulties related to the school closure, including interruption of employment and pay, loss of access to subsidized school meals, and arrangement of alternative childcare. We analyzed this information in the context of certain demographic characteristics of the survey respondents and households, such as race, level of education, and income. We also estimated the average number of lost work days and documented the childcare alternatives chosen by households affected by the school closure.We received 2,229 (28.4% completed surveys from an estimated 7,851 households eligible to participate. About half (1,082 [48.5%] of the households experienced at least some difficulty during the closure, primarily in three areas: uncertainty about duration of the closure, lost income, and the effort of arranging alternate childcare. Adults working outside the home, particularly the major wage earner in the household, were more likely to suffer lost income while schools were closed, an effect mitigated by paid leave benefits. Difficulty arranging childcare was reported most frequently by respondents with lower levels of education and households with younger children. Beyond the top three concerns expressed by households in HCSD, the survey also shed light on the issue of food insecurity when subsidized school meals are not available. Reported by 17.9% of households participating in the subsidized school lunch program, difficulty providing meals during the closure was associated with higher numbers of dependent children, selection of "other" as the race of the household respondent, and lower levels of education.To help prevent undue financial hardship in families of school children, public health authorities and school administrators should provide recommendations for childcare alternatives and paid leave or remote work options during prolonged school closures, particularly to households in which all adults work outside of the home.

    Kalcic, Maria; Iturriaga, Rodolfo H.; Kuper, Philip D.; O'Neal, Stanford Duane; Underwood, Lauren; Fletcher, Rose


    Major changes in salinity (approx.14 ppt.) and temperature (approx.40C) were continuously registered by two prototype NASA DRIFTERs, surface moored floaters, that NASA's Applied Science and Technology Project Office (ASTPO) has developed. The DRIFTER floating sensor module is equipped with an Arduino open-source electronics prototyping platform and programming language (, a GPS (Global Positioning System) module with antenna, a cell phone SIM (Subscriber Identity Module) card and a cellular antenna which is used to transmit data, and a probe to measure temperature and conductivity (from which salinity can be derived). The DRIFTER is powered by a solar cell panel and all the electronic components are mounted and sealed in [ waterproof encasement. Position and measurement data are transmitted via short message service (SMS) messaging to a Twitter site (DRIFTER 002@NASADRIFTER_002 and DRIFTER 004@NASADRIFTER_004), which provides a live feed. These data are the imported into a Google spreadsheet where conductivity is converted to salinity, and graphed in real-time. The spreadsheet data will be imported into a webpage maintained by ASTPO, where it will be displayed available for dO\\\\1lload.

  3. The association between tobacco and the risk of asthma, rhinoconjunctivitis and eczema in children and adolescents: analyses from Phase Three of the ISAAC programme. (United States)

    Mitchell, Edwin A; Beasley, Richard; Keil, Ulrich; Montefort, Stephen; Odhiambo, Joseph


    Exposure to parental smoking is associated with wheeze in early childhood, but in 2006 the US Surgeon General stated that the evidence is insufficient to infer a causal relationship between exposure and asthma in childhood and adolescents. To examine the association between maternal and paternal smoking and symptoms of asthma, eczema and rhinoconjunctivitis. Parents or guardians of children aged 6-7 years completed written questionnaires about symptoms of asthma, rhinoconjunctivitis and eczema, and several risk factors, including maternal smoking in the child's first year of life, current maternal smoking (and amount) and paternal smoking. Adolescents aged 13-14 years self completed the questionnaires on these symptoms and whether their parents currently smoked. In the 6-7-year age group there were 220 407 children from 75 centres in 32 countries. In the 13-14-year age group there were 350 654 adolescents from 118 centres in 53 countries. Maternal and paternal smoking was associated with an increased risk of symptoms of asthma, eczema and rhinoconjunctivitis in both age groups, although the magnitude of the OR is higher for symptoms of asthma than the other outcomes. Maternal smoking is associated with higher ORs than paternal smoking. For asthma symptoms there is a clear dose relationship (1-9 cigarettes/day, OR 1.27; 10-19 cigarettes/day, OR 1.35; and 20+ cigarettes/day, OR 1.56). When maternal smoking in the child's first year of life and current maternal smoking are considered, the main effect is due to maternal smoking in the child's first year of life. There was no interaction between maternal and paternal smoking. This study has confirmed the importance of maternal smoking, and the separate and additional effect of paternal smoking. The presence of a dose-response effect relationship with asthma symptoms suggests that the relationship is causal, however for eczema and rhinoconjunctivitis causality is less certain.

    Full Text Available Diets which emphasize intakes of plant-based foods are recommended to reduce disease risk and for promoting healthy weight. The aim of this study was to examine the association between fruit, vegetables, pulses and nut intake and body mass index (BMI across countries in adolescents (13–14 years and children (6–7 years. Data from the International Study of Asthma and Allergies in Childhood; 77,243 children’s parents and 201,871 adolescents was used to examine the association between dietary intake (Food Frequency Questionnaire and BMI using general linear models, adjusting for country gross national index. Adolescents who consumed fruit, vegetables, pulses and nuts three or more times a week had a lower BMI than the never or occasional group; eating nuts three or more times a week, was associated with a BMI value of 0.274 kg/m2 lower than the never group (p < 0.001. Compared to children who never or occasionally reported eating vegetables, those reporting that they ate vegetables three or more times per week had a lower BMI of −0.079 kg/m2. In this large global study, an inverse association was observed between BMI and the reported increasing intake of vegetables in 6–7 years old and fruit, vegetables, pulses and nuts in adolescents. This study supports current dietary recommendations which emphasize the consumption of vegetables, nut and pulses, although the effect sizes were small.

    When I went to Alaska to study humanity's place in nature, I crafted a short piece of writing as a way to summarize what I learned. The story follows the path of Caleb as he goes through the Alaskan wilderness. His actions contrast heavily with the peaceful ways of Alaska's natives, the Tlingit, and his selfish, materialistic motives clash with those of others he meets. The story ends with him dying alone, succumbing to Mother Nature's defeat. Caleb represents those who utilize natural resources at their own gain, and his journey shows the same trap many others have fallen into.

  13. The Interstellar Conspiracy (United States)

    Johnson, Les; Matloff, Gregory L.


    If we were designing a human-carrying starship that could be launched in the not-too-distant future, it would almost certainly not use a warp drive to instantaneously bounce around the universe, as is done in Isaac Asimov's classic Foundation series or in episodes of Star Trek or Star Wars. Sadly, those starships that seem to be within technological reach could not even travel at high relativistic speeds, as does the interstellar ramjet in Poul Anderson's Tau Zero. Warp-speeds seem to be well outside the realm of currently understood physical law; proton-fusing ramjets may never be technologically feasible. Perhaps fortunately in our terrorist-plagued world, the economics of antimatter may never be attractive for large-scale starship propulsion. But interstellar travel will be possible within a few centuries, although it will certainly not be as fast as we might prefer. If humans learn how to hibernate, perhaps we will sleep our way to the stars, as do the crew in A. E. van Vogt's Far Centaurus. However, as discussed in a landmark paper in The Journal of the British Interplanetary Society, the most feasible approach to transporting a small human population to the planets (if any) of Alpha Centauri is the worldship. Such craft have often been featured in science fiction. See for example Arthur C. Clarke's Rendezvous with Rama, and Robert A. Heinlein's Orphans of the Sky. Worldships are essentially mobile versions of the O Neill free-space habitats. Constructed mostly from lunar and/or asteroidal materials, these solar-powered, multi-kilometer-dimension structures could house 10,000 to 100,000 humans in Earth-approximating environments. Artificial gravity would be provided by habitat rotation, and cosmic ray shielding would be provided by passive methods, such as habitat atmosphere and mass shielding, or magnetic fields. A late 21st century space-habitat venture might support itself economically by constructing large solar-powered satellites to beam energy back to

  16. The evolution of concepts of vestibular peripheral information processing: toward the dynamic, adaptive, parallel processing macular model (United States)

    Ross, Muriel D.


    In a letter to Robert Hooke, written on 5 February, 1675, Isaac Newton wrote "If I have seen further than certain other men it is by standing upon the shoulders of giants." In his context, Newton was referring to the work of Galileo and Kepler, who preceded him. However, every field has its own giants, those men and women who went before us and, often with few tools at their disposal, uncovered the facts that enabled later researchers to advance knowledge in a particular area. This review traces the history of the evolution of views from early giants in the field of vestibular research to modern concepts of vestibular organ organization and function. Emphasis will be placed on the mammalian maculae as peripheral processors of linear accelerations acting on the head. This review shows that early, correct findings were sometimes unfortunately disregarded, impeding later investigations into the structure and function of the vestibular organs. The central themes are that the macular organs are highly complex, dynamic, adaptive, distributed parallel processors of information, and that historical references can help us to understand our own place in advancing knowledge about their complicated structure and functions.

  20. Modeling Mixed Groups of Humans and Robots with Reflexive Game Theory (United States)

    Tarasenko, Sergey

    The Reflexive Game Theory is based on decision-making principles similar to the ones used by humans. This theory considers groups of subjects and allows to predict which action from the set each subject in the group will choose. It is possible to influence subject's decision in a way that he will make a particular choice. The purpose of this study is to illustrate how robots can refrain humans from risky actions. To determine the risky actions, the Asimov's Three Laws of robotics are employed. By fusing the RGT's power to convince humans on the mental level with Asimov's Laws' safety, we illustrate how robots in the mixed groups of humans and robots can influence on human subjects in order to refrain humans from risky actions. We suggest that this fusion has a potential to device human-like motor behaving and looking robots with the human-like decision-making algorithms.

  10. Making and Using Astronomical Fairy-tales on DVD in Planetarium (United States)

    Goncharova, V. G.


    Teaching and learning of astronomy meets many contradictions: the information should be true, the presentation should be at a professional level yet easy for the teacher, the topic should be related to the everyday life of the students, and have a cultural/historical background; also, it should be understandable for a wide range of ages. We try to meet all these principles making and using a DVD-video "The FairyTale of the Milky Way" which has been presented for several months in the Planetarium of SaintPetersburg, Russia. We present some parts of the tale on screen with comments on the realization of the principles. Astronomy has many places and moments where and when an astronomical idea and discovery shines perfectly for teaching. We selected Prague, the house of Kepler, Christmas evening of the year 1610, the Keplers last Christmas in Prague. He really may have celebrated Christmas with his family just before the smallpox epidemic, which will take the lives of three of them the next year. The Keplers' friend Rudolf II was still the Emperor (for his last year). Kepler really may have shown his children the pages of the just-published Bayer's Atlas of the Constellations. He must have been excited by the discoveries on the southern sky as well as the recent telescopic discoveries by Galileo. He really may have looked at the satellites of Jupiter, the phases of Venus (that was the right month!), the stars and nebula of the Milky Way, the sunspots and lunar craters through one of the telescopes widely distributed in 1610. He wrote 2 books: one about stars (the famous planetary laws!), the other about snowflakes. That was the key moment of his life. Many details making the atmosphere of the moment are in our tale. The real pictures of the epoch are used. In the fairytale, the beautiful telescopic nebula on modern photos appear real: "Helix," "Crab," "Ant," "Cat's Eye," "Butterfly," "Witch," and so on. A simple technique and software to make it is presented. The

    Full Text Available Humans are rather funny things, we often tend to imagine that we are so ?special?, so divorced by our supposed ?intelligence? from the influences of the ?natural world? and so unique in our ?abstracting? abilities. We have this persistent delusion, evident since ancient Greek times, that we are ?rational?, that we can behave as ?disinterested observers? of our world, which manifests in AI thought today in a belief that, in a like manner, we can ?design?, God like, from afar, our replacements, those ?super-robots? that will do everything that we can imagine doing, but in much ?better? ways than we can achieve, and yet can avoid doing anything ?nasty?, i.e. can overcome our many human failings - obeying, I suppose, in the process, Asimov?s three ?laws of robotics?. Such human naiveté proves, in fact, to be quite amusing, at least to those of us ?schooled? in AI history. When we look at the aspirations and the expectations of our early ?pioneers?, and compare them to the actual reality of today, then we must, it seems, re-discover the meaning of the word ?humility?. Enthusiasm, good as it may be, needs to be moderated with a touch of ?common sense?, and if our current ways of doing things in our AI world don?t really work as we had hoped, then perhaps it is time to try something different (Lucas, C., 1999?

  18. Catching the Light - The Entwined History of Light and Mind (United States)

    Zajonc, Arthur


    In 1910, the surgeons Moreau and LePrince wrote about their successful operation on an eight-year-old boy who had been blind since birth because of cataracts. When the boy's eyes were healed they removed the bandages and, waving a hand in front of the child's physically perfect eyes, asked him what he saw. "I don't know," was his only reply. What he saw was only a varying brightness in front of him. However, when allowed to touch the hand as it began to move, he cried out in a voice of triumph, "It's moving!" He could feel it move, but he still needed laboriously to learn to see it move. Light and eyes were not enough to grant him sight. How, then, do we see? What's the difference between seeing and perception? What is light? From ancient times to the present, from philosophers to quantum physicists, nothing has so perplexed, so fascinated, so captivated the mind as the elusive definition of light. In Catching the Light , Arthur Zajonc takes us on an epic journey into history, tracing how humans have endeavored to understand the phenomenon of light. Blending mythology, religion, science, literature, and painting, Zajonc reveals in poetic detail the human struggle to identify the vital connection between the outer light of nature and the inner light of the human spirit. He explains the curiousness of the Greeks' blue and green "color blindness": Odysseus gazing longingly at the "wine-dark sea"; the use of chloros (green) as the color of honey in Homer's Odessey ; and Euripides' use of the color green to describe the hue of tears and blood. He demonstrates the complexity of perception through the work of Paul Cézanne--the artist standing on the bank of a river, painting the same scene over and over again, the motifs multiplying before his eyes. And Zajonc goes on to show how our quest for an understanding of light, as well as the conclusions we draw, reveals as much about the nature of our own psyche as it does about the nature of light itself. For the ancient

    Full Text Available Human beings desire immortality as well as they desire the role of God. Having power and using this power over weak people is one of the oldest behaviors of humankind. One of the most important psychological causes of slave trade, almost as old as human history, is undoubtedly the desire of the human to play the immortal God role. We can see this demand in The Epic of Gilgamesh, Beowulf and The Iliad, which are the earliest written works. We witness the search for the immortality and domination of heroes and anti-heroes in works such as Frankenstein or the Modern Prometheus, I, Robot and The Robots of Dawn in contemporary literary period. In many of these quests, the man's desire for absolute domination and for immortality cause him to confront God with the desire to produce (or create something. On the other hand, in contemporary films such as Batman vs Superman: Dawn of Justice, which is adapted to the motion picture screen, it seems that when the man tries to go beyond himself due to his limitless desire of mastership, he confronts a god, Superman. In the science fiction works of our era, the tendency of man to dominate has begun to turn into chaotic robot-human relationship from old slavery-master relationship like in Asimov’s works. The Terminator or The Matrix series are the best examples for this. Therefore, the article will try to establish the theory of confusion and chaos that people encounter while playing the role of God. In doing so, this theory will be tried to be supported by Asimov's I, Robot, The Robots of Dawn, and Robot Visions novels in the light of some quotations. This article, of course, will also examine the tendency to claim everything in what man thinks he can benefit, rather than simply centering Asimov's works. Are these robots equipped with advanced artificial intelligence going to revolt against the people who produce themselves as Cain rebels against God? Consequently, this work will discuss the point where the

  20. Pseudo-differential operators and generalized functions

    CERN Document Server

    Toft, Joachim


    This book gathers peer-reviewed contributions representing modern trends in the theory of generalized functions and pseudo-differential operators. It is dedicated to Professor Michael Oberguggenberger (Innsbruck University, Austria) in honour of his 60th birthday. The topics covered were suggested by the ISAAC Group in Generalized Functions (GF) and the ISAAC Group in Pseudo-Differential Operators (IGPDO), which met at the 9th ISAAC congress in Krakow, Poland in August 2013. Topics include Columbeau algebras, ultra-distributions, partial differential equations, micro-local analysis, harmonic analysis, global analysis, geometry, quantization, mathematical physics, and time-frequency analysis. Featuring both essays and research articles, the book will be of great interest to graduate students and researchers working in analysis, PDE and mathematical physics, while also offering a valuable complement to the volumes on this topic previously published in the OT series.

  1. Holy sci-fi! where science fiction and religion intersect

    CERN Document Server

    Nahin, Paul J


    Can a computer have a soul? Are religion and science mutually exclusive? Is there really such a thing as free will? If you could time travel to visit Jesus, would you (and should you)? For hundreds of years, philosophers, scientists, and science fiction writers have pondered these questions and many more. In Holy Sci-Fi!, popular writer Paul Nahin explores the fertile and sometimes uneasy relationship between science fiction and religion. With a scope spanning the history of religion, philosophy, and literature, Nahin follows religious themes in science fiction from Feynman to Foucault, and from Asimov to Aristotle. An intriguing journey through popular and well-loved books and stories, Holy Sci-Fi! shows how sci-fi has informed humanity's attitudes towards our faiths, our future, and ourselves.

  2. Singularity now: using the ventricular assist device as a model for future human-robotic physiology. (United States)

    Martin, Archer K


    In our 21 st century world, human-robotic interactions are far more complicated than Asimov predicted in 1942. The future of human-robotic interactions includes human-robotic machine hybrids with an integrated physiology, working together to achieve an enhanced level of baseline human physiological performance. This achievement can be described as a biological Singularity. I argue that this time of Singularity cannot be met by current biological technologies, and that human-robotic physiology must be integrated for the Singularity to occur. In order to conquer the challenges we face regarding human-robotic physiology, we first need to identify a working model in today's world. Once identified, this model can form the basis for the study, creation, expansion, and optimization of human-robotic hybrid physiology. In this paper, I present and defend the line of argument that currently this kind of model (proposed to be named "IshBot") can best be studied in ventricular assist devices - VAD.

  3. The Three Laws of Neurorobotics: A Review on What Neurorehabilitation Robots Should Do for Patients and Clinicians. (United States)

    Iosa, Marco; Morone, Giovanni; Cherubini, Andrea; Paolucci, Stefano

    Most studies and reviews on robots for neurorehabilitation focus on their effectiveness. These studies often report inconsistent results. This and many other reasons limit the credit given to these robots by therapists and patients. Further, neurorehabilitation is often still based on therapists' expertise, with competition among different schools of thought, generating substantial uncertainty about what exactly a neurorehabilitation robot should do. Little attention has been given to ethics. This review adopts a new approach, inspired by Asimov's three laws of robotics and based on the most recent studies in neurorobotics, for proposing new guidelines for designing and using robots for neurorehabilitation. We propose three laws of neurorobotics based on the ethical need for safe and effective robots, the redefinition of their role as therapist helpers, and the need for clear and transparent human-machine interfaces. These laws may allow engineers and clinicians to work closely together on a new generation of neurorobots.

    Food allergy (FA) is a worldwide problem, with increasing prevalence in many countries, and it poses a clearly increasing health problem in Korea. In Korea, as a part of International Study of Asthma and Allergy in Childhood (ISAAC), a series of nation-wide population studies for prevalence of allergic disease in children were carried out, with the Korean version of ISAAC in 1995, 2000, and 2010. From the survey, the twelve-month prevalence of FA showed no significant differences from 1995 to...

The author connects Kireyevsky’santhropology with Orthodox practice of the so-called «prayer of the mind», the final aimof which is deification of man’s nature. Kireyevsky’s gnoseology is rooted in St. Isaac theSyrian’s teaching about three stages of cognition. The highest stage, according toSt. Isaac, is the mystical vision of God.

    The goal of the Integrated Solar-Panel Antenna Array for CubeSats (ISAAC) project is to design and demonstrate an effective and efficien toptically transparent, high-gain, lightweight, conformal X-band antenna array that is integrated with the solar panels of a CubeSat. The targeted demonstration is for a Near Earth Network (NEN)radio at X-band, but the design can be easilyscaled to other network radios for higher frequencies. ISAAC is a less expensive and more flexible design for communication systemscompared to a deployed dish antenna or the existing integrated solar panel antenna design.

  16. Improvement of Severe Accident Analysis Computer Code and Development of Accident Management Guidance for Heavy Water Reactor

    International Nuclear Information System (INIS)

    Park, Soo Yong; Kim, Ko Ryu; Kim, Dong Ha; Kim, See Darl; Song, Yong Mann; Choi, Young; Jin, Young Ho


    The objective of the project is to develop a generic severe accident management guidance(SAMG) applicable to Korean PHWR and the objective of this 3 year continued phase is to construct a base of the generic SAMG. Another objective is to improve a domestic computer code, ISAAC (Integrated Severe Accident Analysis code for CANDU), which still has many deficiencies to be improved in order to apply for the SAMG development. The scope and contents performed in this Phase-2 are as follows: The characteristics of major design and operation for the domestic Wolsong NPP are analyzed from the severe accident aspects. On the basis, preliminary strategies for SAM of PHWR are selected. The information needed for SAM and the methods to get that information are analyzed. Both the individual strategies applicable for accident mitigation under PHWR severe accident conditions and the technical background for those strategies are developed. A new version of ISAAC 2.0 has been developed after analyzing and modifying the existing models of ISAAC 1.0. The general SAMG applicable for PHWRs confirms severe accident management techniques for emergencies, provides the base technique to develop the plant specific SAMG by utility company and finally contributes to the public safety enhancement as a NPP safety assuring step. The ISAAC code will be used inevitably for the PSA, living PSA, severe accident analysis, SAM program development and operator training in PHWR

    This volume consists of papers presented in the special sessions on "Complex and Numerical Analysis", "Value Distribution Theory and Complex Domains", and "Use of Symbolic Computation in Mathematics Education" of the ISAAC'97 Congress held at the University of Delaware, during June 2-7, 1997. The ISAAC Congress coincided with a U.S.-Japan Seminar also held at the University of Delaware. The latter was supported by the National Science Foundation through Grant INT-9603029 and the Japan Society for the Promotion of Science through Grant MTCS-134. It was natural that the participants of both meetings should interact and consequently several persons attending the Congress also presented papers in the Seminar. The success of the ISAAC Congress and the U.S.-Japan Seminar has led to the ISAAC'99 Congress being held in Fukuoka, Japan during August 1999. Many of the same participants will return to this Seminar. Indeed, it appears that the spirit of the U.S.-Japan Seminar will be continued every second year as part of...

  19. Improvement of Severe Accident Analysis Computer Code and Development of Accident Management Guidance for Heavy Water Reactor

    Energy Technology Data Exchange (ETDEWEB)

    Park, Soo Yong; Kim, Ko Ryu; Kim, Dong Ha; Kim, See Darl; Song, Yong Mann; Choi, Young; Jin, Young Ho


    The objective of the project is to develop a generic severe accident management guidance(SAMG) applicable to Korean PHWR and the objective of this 3 year continued phase is to construct a base of the generic SAMG. Another objective is to improve a domestic computer code, ISAAC (Integrated Severe Accident Analysis code for CANDU), which still has many deficiencies to be improved in order to apply for the SAMG development. The scope and contents performed in this Phase-2 are as follows: The characteristics of major design and operation for the domestic Wolsong NPP are analyzed from the severe accident aspects. On the basis, preliminary strategies for SAM of PHWR are selected. The information needed for SAM and the methods to get that information are analyzed. Both the individual strategies applicable for accident mitigation under PHWR severe accident conditions and the technical background for those strategies are developed. A new version of ISAAC 2.0 has been developed after analyzing and modifying the existing models of ISAAC 1.0. The general SAMG applicable for PHWRs confirms severe accident management techniques for emergencies, provides the base technique to develop the plant specific SAMG by utility company and finally contributes to the public safety enhancement as a NPP safety assuring step. The ISAAC code will be used inevitably for the PSA, living PSA, severe accident analysis, SAM program development and operator training in PHWR.

  16. Wetland Accretion Rates Along Coastal Louisiana: Spatial and Temporal Variability in Light of Hurricane Isaac’s Impacts

    Directory of Open Access Journals (Sweden)

    Thomas A. Bianchette


    Full Text Available The wetlands of the southern Louisiana coast are disappearing due to a host of environmental stressors. Thus, it is imperative to analyze the spatial and temporal variability of wetland vertical accretion rates. A key question in accretion concerns the role of landfalling hurricanes as a land-building agent, due to their propensity to deposit significant volumes of inorganic sediments. Since 1996, thousands of accretion measurements have been made at 390 sites across coastal Louisiana as a result of a regional monitoring network, called the Coastal Reference Monitoring System (CRMS. We utilized this dataset to analyze the spatial and temporal patterns of accretion by mapping rates during time periods before, around, and after the landfall of Hurricane Isaac (2012. This analysis is vital for quantifying the role of hurricanes as a land-building agent and for understanding the main mechanism causing heightened wetland accretion. The results show that accretion rates averaged about 2.89 cm/year from stations sampled before Isaac, 4.04 cm/year during the period encompassing Isaac, and 2.38 cm/year from sites established and sampled after Isaac. Accretion rates attributable to Isaac’s effects were therefore 40% and 70% greater than before and after the event, respectively, indicating the event’s importance toward coastal land-building. Accretion associated with Isaac was highest at sites located 70 kilometers from the storm track, particularly those near the Mississippi River and its adjacent distributaries and lakes. This spatial pattern of elevated accretion rates indicates that freshwater flooding from fluvial channels, rather than storm surge from the sea per se, is the main mechanism responsible for increased wetland accretion. This significance of riverine flooding has implications toward future coastal restoration policies and practices.

  17. Application of a microcomputer-based system to control and monitor bacterial growth. (United States)

    Titus, J A; Luli, G W; Dekleva, M L; Strohl, W R


    A modular microcomputer-based system was developed to control and monitor various modes of bacterial growth. The control system was composed of an Apple II Plus microcomputer with 64-kilobyte random-access memory; a Cyborg ISAAC model 91A multichannel analog-to-digital and digital-to-analog converter; paired MRR-1 pH, pO(2), and foam control units; and in-house-designed relay, servo control, and turbidimetry systems. To demonstrate the flexibility of the system, we grew bacteria under various computer-controlled and monitored modes of growth, including batch, turbidostat, and chemostat systems. The Apple-ISAAC system was programmed in Labsoft BASIC (extended Applesoft) with an average control program using ca. 6 to 8 kilobytes of memory and up to 30 kilobytes for datum arrays. This modular microcomputer-based control system was easily coupled to laboratory scale fermentors for a variety of fermentations.

    Conclusions: The asthma prevalence in Mongolian children was higher than that in the world and Asia–Pacific countries reported by ISAAC. The higher prevalence was probably attributable to households' (especially mothers smoking in draft-free houses designed for the cold area and severe air-pollution due to rapid industrialization and urbanization in Mongolia. Smoking prohibition in the mother (including family members and a reduction of exposure to air pollutants are urgently needed to prevent developing childhood asthma.

    As Isaac Newton discovered in Mechanics, and published in his Principia Mathematica in 1687, inertial effects are essential to describe natural phenomena. In the case of Fluid Dynamics, inertia was included by Claude-Louis Navier and George Gabriel Stokes almost two centuries after in 1822 when calculating the mass and momentum conservation of au infinitesimal fluid elemeut. Although Navier-Stokes equations are very useful for describing any event of any liquid or gas and there...

  3. Newton's Metaphysics of Space as God's Emanative Effect (United States)

    Jacquette, Dale


    In several of his writings, Isaac Newton proposed that physical space is God's "emanative effect" or "sensorium," revealing something interesting about the metaphysics underlying his mathematical physics. Newton's conjectures depart from Plato and Aristotle's metaphysics of space and from classical and Cambridge Neoplatonism. Present-day philosophical concepts of supervenience clarify Newton's ideas about space and offer a portrait of Newton not only as a mathematical physicist but an independent-minded rationalist philosopher.

  5. Prevalence of Group A beta-haemolytic Streptococcus isolated from children with acute pharyngotonsillitis in Aden, Yemen. (United States)

    Ba-Saddik, I A; Munibari, A A; Alhilali, A M; Ismail, S M; Murshed, F M; Coulter, J B S; Cuevas, L E; Hart, C A; Brabin, B J; Parry, C M


    To estimate the prevalence of Group A beta-haemolytic streptococcus (GAS) and non-GAS infections among children with acute pharyngotonsillitis in Aden, Yemen, to evaluate the value of a rapid diagnostic test and the McIsaac score for patient management in this setting and to determine the occurrence of emm genotypes among a subset of GAS isolated from children with acute pharyngotonsillitis and a history of acute rheumatic fever (ARF) or rheumatic heart disease (RHD). Group A beta-haemolytic streptococcus infections in school-aged children with acute pharyngotonsillitis in Aden, Yemen, were diagnosed by a rapid GAS antigen detection test (RADT) and/or GAS culture from a throat swab. The RADT value and the McIsaac screening score for patient management were evaluated. The emm genotype of a subset of GAS isolates was determined. Group A beta-haemolytic streptococcus pharyngotonsillitis was diagnosed in 287/691 (41.5%; 95% CI 37.8-45.3) children. Group B, Group C and Group G beta-haemolytic streptococci were isolated from 4.3% children. The RADT had a sensitivity of 238/258 (92.2%) and specificity of 404/423 (95.5%) against GAS culture. A McIsaac score of ≥4 had a sensitivity of 93% and a specificity of 82% for confirmed GAS infection. The emm genotypes in 21 GAS isolates from children with pharyngitis and a history of ARF and confirmed RHD were emm87 (11), emm12 (6), emm28 (3) and emm5 (1). This study demonstrates a very high prevalence of GAS infections in Yemeni children and the value of the RADT and the McIsaac score in this setting. More extensive emm genotyping is necessary to understand the local epidemiology of circulating strains. © 2014 John Wiley & Sons Ltd.

  6. Ideas of Physical Forces and Differential Calculus in Ancient India


    Girish, T. E.; Nair, C. Radhakrishnan


    We have studied the context and development of the ideas of physical forces and differential calculus in ancient India by studying relevant literature related to both astrology and astronomy since pre-Greek periods. The concept of Naisargika Bala (natural force) discussed in Hora texts from India is defined to be proportional to planetary size and inversely related to planetary distance. This idea developed several centuries prior to Isaac Newton resembles fundamental physical forces in natur...

  8. Should Research Always be OPEN


    Taylor, Mike


    "If I have seen further it is by standing on the shoulders of giants", said Isaac Newton. Since the earliest days of science, progress has always been achieved by the free exchange and re-use of ideas. Understanding this, scientists have always leaned in the direction of openness. Science outside of trade secrets and state secrets has a natural tendency to be open. Until recently, the principle barrier to sharing science has been the logistic difficulty of printing and distributing copies...

  12. Spectral properties of near-Earth asteroids on cometary orbits (United States)

    Popescu, M.; Vaduvescu, O.; de Leon, J.; Boaca, I. L.; Gherase, R. M.; Nedelcu, D. A.; INT students, I. N. G.


    We studied the spectral distributions of near-Earth asteroids on cometary orbits (NEACOs) in order to identify potential dormant or extinct comets among these objects. We present the spectral observations for 19 NEACOs obtained with Isaac Newton Telescope and Infrared Telescope Facility (IRTF). Although initially classified as asteroid, one of our targets - 2007 VA85 was confirmed to be active comet 333P/LINEAR on its 2016 appearance. We found that the NEACOs population is a mixing of different compositional classes.

  17. On the revolution of heavenly spheres

    CERN Document Server

    Copernicus, Nicolaus


    The Ptolemaic system of the universe, with the earth at the center, had held sway since antiquity as authoritative in philosophy, science, and church teaching. Following his observations of the heavenly bodies, Nicolaus Copernicus (1473-1543) abandoned the geocentric system for a heliocentric model, with the sun at the center. His remarkable work, On the Revolutions of Heavenly Spheres, stands as one of the greatest intellectual revolutions of all time, and profoundly influenced, among others, Galileo and Sir Isaac Newton.

    By stating that a linear differential form, whose coefficients are the components of the momentum and the energy of a particle, has an antiderivative, the basic equations of the dynamics of points are obtained, in the relativistic case. From the point of view of optimization theory, a connection between our condition and the Bellman-Isaacs equation of dynamic programming is discussed, with a view to extending the theory to relativistic wave mechanics [fr

    Dirceu Solé


    Full Text Available OBJECTIVE: To determine the prevalence of symptoms of asthma, rhinitis, and atopic eczema in adolescents (AD; 13-14 years living in seven Brazilian cities, by applying the standardized written questionnaire (WQ of the International Study of Asthma and Allergies in Childhood (ISAAC, and to evaluate the time trend nine years after the last assessment of ISAAC phase 3 (ISP3. METHODS: The ISAAC-WQ was answered by 20,099 AD from the Northern, Northeastern, Southeastern, and Southern Brazilian regions. Values obtained were compared to those observed in ISP3 using nonparametric (chi-squared or Fisher tests, and the ratio of annual increment/decrement was established for each of the centers, according to the symptom assessed. RESULTS: Considering the national data and comparing to values of ISP3, there was a decrease in the mean prevalence of active asthma (18.5% vs. 17.5% and an increase in the frequency of severe asthma (4.5% vs. 4.7% and physician-diagnosed asthma (14.3% vs. 17.6%. An increase in prevalence of rhinitis, rhinoconjunctivitis, and atopic eczema was also observed. CONCLUSIONS: The prevalence of asthma, rhinitis, and atopic eczema in Brazil was variable; higher prevalence values, especially of asthma and eczema, were observed in regions located closer to the Equator.

  17. Prediction of hydrogen distribution in the reactor building in CANDU6 plant

    International Nuclear Information System (INIS)

    Jin, Y.; Song, Y.


    The CANDU plants have a lot of zircaloy. The fuel cladding, calandria tubes and pressure tubes are made of zircaloy. The zircaloy can be oxidized and hydrogen is generated during severe accident progression. The detonation or deflagration to detonation transition (DDT) due to hydrogen combustion may occur if the local hydrogen concentration or global hydrogen concentration exceeds certain value. The detonation may result in the rupture of the reactor building. The inside of the reactor building of CANDU plants is complex. So prediction of hydrogen distribution in the reactor building is important. This prediction is made using ISAAC code and GOTHIC code. ISAAC code partitioned the reactor building in to 7 compartments. GOTHIC code modeled the CANDU6 reactor building using 12 nodes. The hydrogen concentrations in the various compartments in the reactor building are compared. GOTHIC code slightly underpredicts hydrogen concentration in the F/M rooms than ISAAC code, but trend is same. The hydrogen concentration in the boiler room and the moderator room shows almost same as for both codes. (author)

    The aim of this paper is to give an inside view to the REXUS/BEXUS programme from the perspective of a student who has been involved in the project. Each year, the German Aerospace Center (DLR) and the Swedish National Space Board (SNSB), in cooperation with the European Space Agency (ESA), offer the opportunity to European University Students to fly an experiment on board sounding rockets or stratospheric balloons in the frame of the REXUS/BEXUS programme. From December 2012 to May 2014 a team of master students from KTH, the Royal Institute of Technology, worked on ISAAC project, an atmospheric experiment launched on board REXUS 15. The author was part of this student team and was involved in the whole process of the ISAAC project from design building and testing phases to the launch campaign and results analysis. The points raised in this article were presented on the occasion of a keynote speech during the 22nd ESA Symposium on European Rocket and Balloon Programmes and Related Research, in Tromsø (Norway) from the 7th to the 12th ofJune 2015. The aim of this presentation was to demonstrate the benefits of hands-on Education programme at University level. In addition to the research opportunities, future space engineers and scientists can profit from a first practical experience under the supervision of experimented experts. The results of the ISAAC project were also presented in the frame of this conference [1].

    Kumiya Sugiyama


    Full Text Available To analyze the prevalence and severity of asthma, rhinitis and eczema in children living in different countries, the International Study of Asthma and Allergies in Childhood (ISAAC was developed. The ISAAC Phase One study evaluated approximately 720 000 children in 56 countries, including Japan. In late 1995 and early 1996, we administered the ISAAC questionnaire to 4466 schoolchildren aged 13–14 years of age in 24 schools in Utsunomiya City and Tochigi City (both in Tochigi Prefecture, Japan. With regard to asthma, the reported prevalence of wheezing in the preceding 12 months was 8.4%, of frequent wheezing attacks 0.6% and of wheezing with sleep disturbance 0.5%. The prevalence in the preceding 12 months of rhinitis was 42.1% and of rhinoconjunctivitis was 21.5%. Nasal symptoms were most frequent in April (19.9% and least frequent in July (5.6%. The prevalence of atopic eczema in the prior 12 months was 9.6% and atopic eczema with sleep disturbance was 0.6%. All prevalence values were slightly increased in Utsunomiya City, the largest city in Tochigi Prefecture, in comparison with Tochigi City. In conclusion, in Japanese cities, 33.3% of children had some allergic symptoms and 2.4% of children reported severe allergic symptoms.

  2. PINGU sensitivity to neutrino mass hierarchy

    International Nuclear Information System (INIS)

    Groß, Andreas


    Determination of the neutrino mass hierarchy (NMH) is among the most fundamental questions in particle physics. Recent measurements of 1) a large mixing angle between the first and the third neutrino mass eigenstates and 2) the first observation of atmospheric neutrino oscillations at tens of GeV with neutrino telescopes, open the intriguing new possibility to exploit matter effects in neutrino oscillation to determine the neutrino mass hierarchy. A further extension of IceCube/DeepCore called PINGU (Precision IceCube Next Generation Upgrade) has been recently envisioned with the ultimate goal to measure neutrino mass hierarchy. PINGU would consist of additional IceCube-like strings of detectors deployed in the deepest and cleanest ice in the center of IceCube. More densely deployed instrumentation would provide a threshold substantially below 10 GeV and enhance the sensitivity to the mass hierarchy signal in atmospheric neutrinos.

    CERN Document Server


    Dark matter is hypothesized to constitute about 80% of the total matter in the universe. While existence and effects of dark matter are quite evident in astrophysical observations, it has not yet been experimentally observed. Besides direct and indirect searches for dark matter, collider experiments also present us with a possibility to produce and detect dark matter in the laboratory. A search for dark matter produced in association with bottom quarks in proton-proton collisions at a center of mass energy of $\\sqrt{s}$ = 13 TeV is presented in this thesis. The data collected by the Compact Muon Solenoid (CMS) experiment at CERN in 2016 is used for the analysis. We look at a final state containing high missing transverse energy and one or two jets produced from bottom quarks. Several control regions are defined to model the major backgrounds present in the signal regions. Hence, the signal is extracted through simultaneous fits on the signal and control regions. The results are interpreted by finding Asimov l...

  4. Clinical skills-related learning goals of senior medical students after performance feedback. (United States)

    Chang, Anna; Chou, Calvin L; Teherani, Arianne; Hauer, Karen E


    Lifelong learning is essential for doctors to maintain competence in clinical skills. With performance feedback, learners should be able to formulate specific and achievable learning goals in areas of need. We aimed to determine: (i) the type and specificity of medical student learning goals after a required clinical performance examination; (ii) differences in goal setting among low, average and high performers, and (iii) whether low performers articulate learning goals that are concordant with their learning needs. We conducted a single-site, multi-year, descriptive comparison study. Senior medical students were given performance benchmarks, individual feedback and guidelines on learning goals; each student was subsequently instructed to write two clinical skills learning goals. Investigators coded the learning goals for specificity, categorised the goals, and performed statistical analyses to determine their concordance with student performance level (low, average or high) in data gathering (history taking and physical examination) or communication skills. All 208 students each wrote two learning goals and most (n=200, 96%) wrote two specific learning goals. Nearly two-thirds of low performers in data gathering wrote at least one learning goal that referred to history taking or physical examination; one-third wrote learning goals pertaining to the organisation of the encounter. High performers in data gathering wrote significantly more patient education goals and significantly fewer history-taking goals than average or low performers. Only 50% of low performers in communication wrote learning goals related to communication skills. Low performers in communication were significantly more likely than average or high performers to identify learning goals related to improving performance in future examinations. The provision of performance benchmarking, individual feedback and brief written guidelines helped most senior medical students in our study to write specific

    In previous study, we recorded electroencephalogram (EEG) of patients with dementia and healthy subjects during Sternberg task. But, only one presentation method of Sternberg task was considered in previous study. Therefore, we examined whether the EEG was different in two different presentation methods wrote letters horizontally and wrote letters vertically in this study. We recorded EEG of six healthy subjects during Sternberg task using two different presentation methods. The result was not different in EEG topography of all subjects. In all subjects, correct rate increased in case of vertically arranged letters.

    Full Text Available Lying in his death bed in 1776, David Hume wrote a moving letter of good-bye to Madame Boufflers, with whom he was almost certainly in love.  "I see death approach gradually without any anxiety or regret," wrote Hume to the Comtesse, adding, "I salute you, with great affection and regard, for the last time."  It is hard to think that Hume would not have, at that time, looked nostalgically also at the world of ideas and reflections, to which too he was saying goodbye, and with which he was als...

  9. Witkacy’s Amusia


    Bocheński, Tomasz


    Witkacy suffered from amusia as a child and as an adult person. He was seriously interested in music only for a little over twenty years (1890–1914?). He wrote his main works as an amusic. The relation between amusia and metaphysical feelings may suggest that Witkacy wrote dramas and created painting compositions in order to evoke the lost strangeness of being. Amusia could have also been the reason for Witkacy’s ambiguity – he was defending and degrading high art at the same time.

  11. 150 years of Freud-Kraepelin dualism. (United States)

    Trede, Katharina


    The year 2006 marked the 150th Birthday of Emil Kraepelin and Sigmund Freud. Kraepelin and Freud were two very different yet very similar men. The comparison between their biographies shows many parallels in their lives and personalities. They were, in their time, the two most influential individuals in psychiatry. They wrote and thought about similar topics in the field yet came to quite different conclusions. Both did not show public respect for each other but wrote about the importance of integrating their respective approaches into the study of the mind/brain problem. Psychiatry today continues to struggle with the integration of the biological and psychodynamic approach.
