    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.

    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

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.

There are few reports in Latino american countries. A 31 year-old man with sustained muscular contractions in lower limbs and diffuse myokymias since he was eighteen-year old. Dextrocardia was disclosed on clinical examination. We report the case of a patient with Isaacs syndrome and dextrocardia.

  19. Isaac Newton and the astronomical refraction.

    Science.gov (United States)

    Lehn, Waldemar H

    2008-12-01

    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.

    It has been previously established that extraverts who are skilled at interpersonal interaction perform significantly better than introverts on a face-specific recognition memory task. In our experiment we further investigate the relationship between extraversion and face recognition, focusing on famous face recognition and face matching. Results indicate that more extraverted individuals perform significantly better on an upright famous face recognition task and show significantly larger face inversion effects. However, our results did not find an effect of extraversion on face matching or inverted famous face recognition.

  1. Improvement of core degradation model in ISAAC

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

    2004-02-01

    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

  4. Isaac Newton: Eighteenth-century Perspectives

    Science.gov (United States)

    Hall, A. Rupert

    1999-05-01

    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

  11. How fast is famous face recognition?

    Directory of Open Access Journals (Sweden)

    Gladys eBarragan-Jason

    2012-10-01

    Full Text Available The rapid recognition of familiar faces is crucial for social interactions. However the actual speed with which recognition can be achieved remains largely unknown as most studies have been carried out without any speed constraints. Different paradigms have been used, leading to conflicting results, and although many authors suggest that face recognition is fast, the speed of face recognition has not been directly compared to fast visual tasks. In this study, we sought to overcome these limitations. Subjects performed three tasks, a familiarity categorization task (famous faces among unknown faces, a superordinate categorization task (human faces among animal ones and a gender categorization task. All tasks were performed under speed constraints. The results show that, despite the use of speed constraints, subjects were slow when they had to categorize famous faces: minimum reaction time was 467 ms, which is 180 ms more than during superordinate categorization and 160 ms more than in the gender condition. Our results are compatible with a hierarchy of face processing from the superordinate level to the familiarity level. The processes taking place between detection and recognition need to be investigated in detail.

  12. Franklin Delano Roosevelt: a famous patient.

    Science.gov (United States)

    Hart, Curtis W

    2014-08-01

    Franklin Delano Roosevelt is arguably one of the greatest of American Presidents. His encounter with the polio that crippled him at an early age and its transformative impact upon him are here discussed with particular reference to his relationship with his physician, Dr. George Draper. This transformation liberated energy in Roosevelt to lead and to show empathy for others in ways that both challenged the political and social status quo in the U.S.A. as well as helped save the world from the threat of Fascism in World War II. This essay seeks to demonstrate how an investigation of the life and struggles of this famous patient is one avenue for relating the study of the humanities to medical education. An earlier version of this paper was presented as the Heberden Lecture in the History of Medicine at the New York Academy of Medicine in 2012.

    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.

  14. Famous Stone Patients and Their Disease

    2007-04-01

    The fact that stone patients have endured much throughout the ages and that prior to our current era, when the ultimate horror, "being cut for the stone" was the only alternative to the repeated episodes of colic, should be recalled from time to time. Urolithiasis has affected humanity throughout the ages and has been indiscriminate to those lives it touched. A full accounting of those who have suffered and recorded their agonies is beyond the scope of this investigation; however, even a partial accounting is valuable for present day physicians who care for those with stone disease. For the present work, the historical accounts of stone disease literature were scrutinized for individual sufferers who could be cross-referenced from other sources as legitimately afflicted by stones. Only those patients that could be documented and were (or are) well known were included, because the internet is now a verdant repository of thousands of "not so well knowns." Reliable historical data was found for a variety of persons from the pre-Christian era to the present, including those remembered as philosophers and scientists, physicians, clergy, leaders and rulers, entertainers, athletes and fictitious/Hollywood-type individuals. Verified accounts of famous stone formers were chosen for this paper, and are presented in chronological order. The list of urolithiasis sufferers presented here is undoubtedly incomplete, but it is not through lack of trying that they are missing. Most often, the suffering do so silently, and that is always allowed.

    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.

  19. Hurricane Isaac: observations and analysis of coastal change

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

    2013-01-01

    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 (http://coastal.er.usgs.gov/national-assessment/) 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 (http://coastal.er.usgs.gov/hurricanes/) 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

  20. The illusion of fame: how the nonfamous become famous.

    Landau, Joshua D; Leed, Stacey A

    2012-01-01

    This article reports 2 experiments in which nonfamous faces were paired with famous (e.g., Oprah Winfrey) or semifamous (e.g., Annika Sorenstam) faces during an initial orienting task. In Experiment 1, the orienting task directed participants to consider the relationship between the paired faces. In Experiment 2, participants considered distinctive qualities of the paired faces. Participants then judged the fame level of old and new nonfamous faces, semifamous faces, and famous faces. Pairing a nonfamous face with a famous face resulted in a higher fame rating than pairing a nonfamous face with a semifamous face. The fame attached to the famous people was misattributed to their nonfamous partners. We discuss this pattern of results in the context of current theoretical explanations of familiarity misattributions.

    Waits, Robert K

    2013-01-01

    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.

    2013-05-01

    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 http://www.ing.iac.es/astronomy/service/.

  3. "To Improve upon Hints of Things": Illustrating Isaac Newton.

    Schilt, Cornelis J

    2016-01-01

    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.

    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.

  9. Catch a falling apple: Isaac Newton and myths of genius.

    Science.gov (United States)

    Fara, P

    1999-01-01

    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.

    2016-08-01

    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.

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

    CERN Document Server

    Aughton, Peter

    2003-01-01

    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...

  13. 'Speaking Kleinian': Susan Isaacs as Ursula Wise and the Inter-War Popularisation of Psychoanalysis.

    Science.gov (United States)

    Shapira, Michal

    2017-10-01

    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.

  14. Accounts of famous North American Wolves, Canis lupus

    Gipson, P.S.; Ballard, W.B.

    1998-01-01

    We examined historical accounts of 59 famous North American Gray Wolves (Canis lupus) reported during the late nineteenth and early twentieth centuries. Fifty of the 59 wolves were purportedly responsible for great losses to livestock, but for 29 reports, evidence suggested that ???2 wolves (e.g., packs) were responsible for the purported kills; in addition, seven wolves had traits that suggested they were hybrids with dogs, and one wolf was probably not from the area where the damage purportedly occurred. Reported livestock losses, especially to Longhorn cattle, from individual wolves appeared excessively high in relation to current literature. Most famous wolves were old and/or impaired from past injuries: 19 were reportedly ???10 years old, 18 had mutilated feet from past trap injuries, and one had a partially severed trachea from being in a snare. Old age and physical impairments probably contributed to livestock depredations by some famous wolves. Several accounts appeared exaggerated, inaccurate, or fabricated. Historical accounts of famous wolves should be interpreted with great caution, especially when considering impacts of wolf reintroductions or when modeling predation rates.

    Science.gov (United States)

    Moreau, Elisabeth

    2011-01-01

    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.

    To study and summarize the academic thoughts of famous Chinese medicine doctors is the main pathway of developing Chinese medicine theories. It is of important significance in enriching and developing the Chinese medicine theories by combining traditional and modern research methods, merging multiple disciples to study the research inherit mode of famous academic thoughts. The major study links include: (1) To refine scientific hypotheses from huge amount of clinical case records; (2) To find the literature sources; (3) To embody the practice significance of the innovative theories by clinical studies; (4) To reveal the scientific connotation of Chinese medicine theories by experimental studies. We hope to reach the goal of innovating and developing Chinese medicine theories on the basis of inheritance by integrating clinical case records, tracing the literature sources, clinical and experimental studies.

    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.

    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.

  3. Intermittent Solar Ammonia Absorption Cycle (ISAAC) refrigeration for lesser developed countries

    Erickson, Donald C.

    1990-02-01

    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.

  6. How to manage a revolution: Isaac Newton in the early twentieth century

    Science.gov (United States)

    Clarke, Imogen

    2014-01-01

    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.

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

    2015-01-01

    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 One of the most exciting and unexpected objects in the 2014 Tate Britain exhibition Kenneth Clark: Looking for Civilization was a prototype plate by Vanessa Bell and Duncan Grant for a dinner service commissioned by Clark in 1932. The completed set of 50 plates, which feature portraits of “famous women” throughout history, survived wartime bombing and several moves of house by the Clark family, but for the past 30 years its whereabouts had been unknown to art historians. In spring 2017, prompted by the Vanessa Bell monographic exhibition at Dulwich Picture Gallery, the owner of the dinner service contacted Piano Nobile art gallery. It soon emerged that not only was the set intact, but that the plates themselves, hand-painted on Wedgwood blanks, have been preserved in their original condition. This Look First feature offers the first opportunity for close scholarly examination of a culturally and visually potent art object. The feature uses photography, archival materials, and film to explore the process of creating the set and its place in the history of art. The present article includes a catalogue with biographical entries for each of the women featured in the set, together with source images and preparatory materials. The article text establishes where this playful, yet ground-breaking work fits within the artists’ oeuvres, and within a feminist history of art. Further materials expanding the feature’s reach, including a filmed discussion with the artist Judy Chicago, will be released in early 2018.

  10. Successful decoding of famous faces in the fusiform face area.

    Vadim Axelrod

    Full Text Available What are the neural mechanisms of face recognition? It is believed that the network of face-selective areas, which spans the occipital, temporal, and frontal cortices, is important in face recognition. A number of previous studies indeed reported that face identity could be discriminated based on patterns of multivoxel activity in the fusiform face area and the anterior temporal lobe. However, given the difficulty in localizing the face-selective area in the anterior temporal lobe, its role in face recognition is still unknown. Furthermore, previous studies limited their analysis to occipito-temporal regions without testing identity decoding in more anterior face-selective regions, such as the amygdala and prefrontal cortex. In the current high-resolution functional Magnetic Resonance Imaging study, we systematically examined the decoding of the identity of famous faces in the temporo-frontal network of face-selective and adjacent non-face-selective regions. A special focus has been put on the face-area in the anterior temporal lobe, which was reliably localized using an optimized scanning protocol. We found that face-identity could be discriminated above chance level only in the fusiform face area. Our results corroborate the role of the fusiform face area in face recognition. Future studies are needed to further explore the role of the more recently discovered anterior face-selective areas in face recognition.

    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. But Isaacs was also a radical liberal politician who carried forward a revolution, in January 1880, moved by his ideological principles in the midst of what he considered to be the treason of the liberals. From the very beginning, this revolution, which was immersed in romanticism, was an enterprise destined to fail. This article, based on the study of documents from that time, analyzes the way in which Isaacs developed his militant activities firstly as an Education inspector, then as a congressman, and finally as a revolutionary in the framework of the recovery process by the conservative party.

    Personally familiar people are likely to be represented more richly in episodic, emotional, and behavioral contexts than famous people, who are usually represented predominantly in semantic context. To reveal cortical mechanisms supporting this differential person representation, we compared cortical activation during name recognition tasks between personally familiar and famous names, using an event-related functional magnetic resonance imaging (fMRI). Normal subjects performed familiar- or unfamiliar-name detection tasks during visual presentation of personally familiar (Personal), famous (Famous), and unfamiliar (Unfamiliar) names. The bilateral temporal poles and anterolateral temporal cortices, as well as the left temporoparietal junction, were activated in the contrasts Personal-Unfamiliar and Famous-Unfamiliar to a similar extent. The bilateral occipitotemporoparietal junctions, precuneus, and posterior cingulate cortex showed activation in the contrasts Personal-Unfamiliar and Personal-Famous. Together with previous findings, differential activation in the occipitotemporoparietal junction, precuneus, and posterior cingulate cortex between personally familiar and famous names is considered to reflect differential person representation. The similar extent of activation for personally familiar and famous names in the temporal pole and anterolateral temporal cortex is consistent with the associative role of the anterior temporal cortex in person identification, which has been conceptualized as a person identity node in many models of person identification. The left temporoparietal junction was considered to process familiar written names. The results illustrated the neural correlates of the person representation as a network of discrete regions in the bilateral posterior cortices, with the anterior temporal cortices having a unique associative role.

    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.

    2004-12-01

    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.

    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.

  20. Leveraging Social Media Data to Understand Disaster Resilience: A Case Study of Hurricane Isaac

    2017-12-01

    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.

  1. VLBA Changes Picture of Famous Star-Forming Region

    2007-10-01

    Using the supersharp radio "vision" of the National Science Foundation's Very Long Baseline Array (VLBA), astronomers have made the most precise measurement ever of the distance to a famous star-forming region. The measurement -- to the heavily studied Orion Nebula -- changes scientists' understanding of the characteristics of the young stars in the region. Parallax Diagram Trigonometric Parallax method determines distance to star by measuring its slight shift in apparent position as seen from opposite ends of Earth's orbit. CREDIT: Bill Saxton, NRAO/AUI/NSF Star Track Apparent track of star GMR A in the Orion Nebula Cluster, showing shift caused by Earth's orbital motion and star's movement in space. CREDIT: Sandstrom et al., NRAO/AUI/NSF Click on Images for Larger Files "This measurement is four times more precise than previous distance estimates. Because our measurement reduces the distance to this region, it tells us that the stars there are less bright than thought before, and changes the estimates of their ages," said Geoff Bower, an astronomer at the University of California at Berkeley. Bower, along with Karin Sandstrom, J.E.G. Peek, Alberto Bolatto and Richard Plambeck, all of Berkeley, published their findings in the October 10 edition of the Astrophysical Journal. The scientists determined the distance to a star called GMR A, one of a cluster of stars in the Orion Nebula, by measuring the slight shift in the star's apparent position in the sky caused by the Earth's motion around the Sun. Observing the star when the Earth is on opposite sides of its annual orbit allows astronomers to measure the angle of this small shift and thus provides a direct trigonometric calculation of its distance. "By using this technique, called parallax, we get a direct measurement that does not depend on various assumptions that are required to use less-direct methods," Bower said. "Only a telescope with the remarkable ability to see fine detail that is provided by the VLBA is

    1999-01-01

    We evaluated the credibility of early literature about famous North American wolves (Canis lupus). Many famous wolves were reported to be older than they actually were, and we estimated they did not live long enough to have caused purported damage to livestock and game animals. Wolf kill rates on free-ranging livestock appeared to be inflated compared to recently published kill rates on native ungulates and livestock. Surplus killing of sheep and goats may have accounted for some high kill rates, but surplus killing of free-ranging longhorn cattle probably did not occur. Some famous wolves may actually have been dogs (C. familiaris), wolf-dog hybrids, or possibly coyote (C. latrans)-dog hybrids. We documented instances where early authors appeared to embellish or fabricate information about famous wolves. Caution should be exercised when using early literature about wolves as a basis for wolf management decisions.

    Frank G. Bosman

    2018-04-01

    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.

  5. ‘Speaking Kleinian’: Susan Isaacs as Ursula Wise and the Inter-War Popularisation of Psychoanalysis

    Science.gov (United States)

    Shapira, Michal

    2017-01-01

    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.

    CERN Document Server

    Harper, William L.

    2014-01-01

    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...

    2000-01-01

    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.

    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.

    Vieira, Carla Costa

    2014-06-20

    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.

  12. 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

    2003-03-01

    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.

    Alcoba, Jesús; López, Laura

    2017-11-01

    Positive psychology focuses on aspects that human beings can improve, thereby enhancing their growth and happiness. One of these aspects is willpower, a quality that has been demonstrated to have various benefits on people, as widely shown in the literature. As a result, a growing body of research is attempting to establish the conditions under which an individual's willpower can be increased. This work attempts to confirm whether the famous quotations that people often use to inspire or motivate themselves can have a real effect on willpower. Two experiments were conducted assigning randomly subjects to a group and priming them with famous quotations, and afterwards comparing their performance in a willpower task with a control group. The second experiment added a willpower depletion task before priming. As a result, primed subjects endured the willpower task significantly more time than control group, demonstrating that famous quotations related to willpower help to increase this capacity and to counteract the effect of willpower depletion.

    2002-12-01

    Complex pictorial information can be represented and retrieved from memory as mental visual images. Functional brain imaging studies have shown that visual perception and visual imagery share common neural substrates. The type of memory (short- or long-term) that mediates the generation of mental images, however, has not been addressed previously. The purpose of this study was to investigate the neural correlates underlying imagery generated from short- and long-term memory (STM and LTM). We used famous faces to localize the visual response during perception and to compare the responses during visual imagery generated from STM (subjects memorized specific pictures of celebrities before the imagery task) and imagery from LTM (subjects imagined famous faces without seeing specific pictures during the experimental session). We found that visual perception of famous faces activated the inferior occipital gyri, lateral fusiform gyri, the superior temporal sulcus, and the amygdala. Small subsets of these face-selective regions were activated during imagery. Additionally, visual imagery of famous faces activated a network of regions composed of bilateral calcarine, hippocampus, precuneus, intraparietal sulcus (IPS), and the inferior frontal gyrus (IFG). In all these regions, imagery generated from STM evoked more activation than imagery from LTM. Regardless of memory type, focusing attention on features of the imagined faces (e.g., eyes, lips, or nose) resulted in increased activation in the right IPS and right IFG. Our results suggest differential effects of memory and attention during the generation and maintenance of mental images of faces.

  18. A description of the FAMOUS (version XDBUA climate model and control run

    2008-12-01

    Full Text Available FAMOUS is an ocean-atmosphere general circulation model of low resolution, capable of simulating approximately 120 years of model climate per wallclock day using current high performance computing facilities. It uses most of the same code as HadCM3, a widely used climate model of higher resolution and computational cost, and has been tuned to reproduce the same climate reasonably well. FAMOUS is useful for climate simulations where the computational cost makes the application of HadCM3 unfeasible, either because of the length of simulation or the size of the ensemble desired. We document a number of scientific and technical improvements to the original version of FAMOUS. These improvements include changes to the parameterisations of ozone and sea-ice which alleviate a significant cold bias from high northern latitudes and the upper troposphere, and the elimination of volume-averaged drifts in ocean tracers. A simple model of the marine carbon cycle has also been included. A particular goal of FAMOUS is to conduct millennial-scale paleoclimate simulations of Quaternary ice ages; to this end, a number of useful changes to the model infrastructure have been made.

  19. Determinants of famous name processing speed: age of acquisition versus semantic connectedness.

    Smith-Spark, James H; Moore, Viv; Valentine, Tim

    2013-02-01

    The age of acquisition (AoA) and the amount of biographical information known about celebrities have been independently shown to influence the processing of famous people. In this experiment, we investigated the facilitative contribution of both factors to famous name processing. Twenty-four mature adults participated in a familiarity judgement task, in which the names of famous people were grouped orthogonally by AoA and by the number of bits of biographical information known about them (number of facts known; NoFK). Age of acquisition was found to have a significant effect on both reaction time (RT) and accuracy of response, but NoFK did not. The RT data also revealed a significant AoA×NoFK interaction. The amount of information known about a celebrity played a facilitative role in the processing of late-acquired, but not early-acquired, celebrities. Once AoA is controlled, it would appear that the semantic system ceases to have a significant overall influence on the processing of famous people. The pre-eminence of AoA over semantic connectedness is considered in the light of current theories of AoA and how their influence might interact. Copyright © 2012 Elsevier B.V. All rights reserved.

  20. Recognizing famous voices: influence of stimulus duration and different types of retrieval cues.

    1997-04-01

    The current investigation measured the effects of increasing stimulus duration on listeners' ability to recognize famous voices. In addition, the investigation studied the influence of different types of cues on the naming of voices that could not be named before. Participants were presented with samples of famous and unfamiliar voices and were asked to decide whether or not the samples were spoken by a famous person. The duration of each sample increased in seven steps from 0.25 s up to a maximum of 2 s. Voice recognition improvements with stimulus duration were with a growth function. Gains were most rapid within the first second and less pronounced thereafter. When participants were unable to name a famous voice, they were cued with either a second voice sample, the occupation, or the initials of the celebrity. Initials were most effective in eliciting the name only when semantic information about the speaker had been accessed prior to cue presentation. Paralleling previous research on face naming, this may indicate that voice naming is contingent on previous activation of person-specific semantic information.

    2014-01-01

    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, ...

    2015-11-01

    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.

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

    2016-12-01

    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.

  9. FAMOUS, faster: using parallel computing techniques to accelerate the FAMOUS/HadCM3 climate model with a focus on the radiative transfer algorithm

    Full Text Available We have optimised the atmospheric radiation algorithm of the FAMOUS climate model on several hardware platforms. The optimisation involved translating the Fortran code to C and restructuring the algorithm around the computation of a single air column. Instead of the existing MPI-based domain decomposition, we used a task queue and a thread pool to schedule the computation of individual columns on the available processors. Finally, four air columns are packed together in a single data structure and computed simultaneously using Single Instruction Multiple Data operations.

    The modified algorithm runs more than 50 times faster on the CELL's Synergistic Processing Element than on its main PowerPC processing element. On Intel-compatible processors, the new radiation code runs 4 times faster. On the tested graphics processor, using OpenCL, we find a speed-up of more than 2.5 times as compared to the original code on the main CPU. Because the radiation code takes more than 60 % of the total CPU time, FAMOUS executes more than twice as fast. Our version of the algorithm returns bit-wise identical results, which demonstrates the robustness of our approach. We estimate that this project required around two and a half man-years of work.

    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.

    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.

    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.

    The inheritance of famous old traditional Chinese medicine (TCM) doctors plays an essential role in the fields of TCM research. Qualitative interviews allow for subjectivity and individuality within clinical experience as well as academic ideas of doctors, making it a potential appropriate research method for inheritance of famous old TCM doctors. We summarized current situations of inheritance research on famous old TCM doctors, and then discussed the feasibility of applying qualitative interviews in inheritance of famous old TCM doctors. By combining our experience in research on inheritance of famous old TCM doctors, we gave some advice on study design, interview implementation, data transcription and analyses , and report writing, providing a reference for further relevant research.

    Full Text Available The personality-descriptive adjectives used in a famous Chinese novel of the 18th century, A Dream of Red Mansions, which is thought to broadly reflect Chinese culture, might help depict personality structure. Four hundred ninety-three personality-descriptive adjectives from the first 80 chapters of the novel were administered to 732 Chinese university students. After factor analyses, the one- to seven-factor solutions were extracted, and the five-factor one was relatively clearer. The five factors of personality titled Wicked, Intelligent, Amiable, Conscientious, and Frank, were intercorrelated. Men scored higher on Wicked and Conscientious but lower on Amiable compared with women. As a preliminary trial, our study demonstrates that personality-descriptive adjectives in a famous Chinese novel characterize the personality structure.

    Famous people with genetic disorders have always been a subject of interest because such news feeds the curiosity the public has for celebrities. It gives further insight into their lives and provides a medical basis for any unexplained or idiosyncratic feature or behavior they exhibit. It draws admiration from society of those who excel in their specialized fields despite the impositions of their genetic illnesses and also elicits sympathy even in the most casual observer. Such news certainly catapults a rare genetic disorder into the realm of public awareness. We hereby present six famous figures: King George III, Toulouse-Lautrec, Queen Victoria, Nicolo Paganini, Abraham Lincoln, and Vincent van Gogh, all of whom made a huge indelible mark in either the history of politics or that of the arts.

  17. Lack of semantic priming effects in famous person recognition in Mild Cognitive Impairment.

    2012-04-01

    Growing evidence indicates that individuals with Mild Cognitive Impairment (MCI) manifest semantic deficits that are often more severe for items that are characterized by a unique semantic and lexical association, such as famous people and famous buildings, than common concepts, such as objects. However, it is still controversial whether the semantic deficits observed in MCI are determined by a degradation of semantic information or by a deficit in intentional access to semantic knowledge. Here we used a semantic priming task in order to assess the integrity of the semantic system without requiring explicit access to this system. This paradigm may provide new insights in clarifying the nature of the semantic deficits in MCI. We assessed the semantic and repetition priming effect in 13 individuals with MCI and 13 age-matched controls who engaged in a familiarity judgment task of famous names. In the semantic priming condition, the prime was the name of a member of the same occupation category as the target (Tom Cruise-Brad Pitt), while in the repetition priming condition the prime was the same name as the target (Charlie Chaplin-Charlie Chaplin). The results showed a defective priming effect in MCI in the semantic but not in the repetition priming condition. Specifically, when compared to controls, MCI patients did not show a facilitation effect in responding to the same occupation prime-target pairs, but they showed an equivalent facilitation effect when the target was the same name as the prime. The present results provide support to the hypothesis that the semantic impairments observed in MCI cannot be uniquely ascribed to a deficit in intentional access to semantic information. Instead, these findings point to the semantic nature of these deficits and, in particular, to a degraded representation of semantic information concerning famous people.

    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

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.

    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.

    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.

    Purpose: The purpose of this study was to evaluate the efficacy of art therapy to control fatigue in cancer patients during course of radiotherapy and its impact on quality of life (QoL). Materials and Methods: Fifty cancer patients receiving radiotherapy received weekly art therapy sessions using famous painting appreciation. Fatigue and QoL were assessed using the Brief Fatigue Inventory (BFI) Scale and the Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) at baseline before starting radiotherapy, every week for 4 weeks during radiotherapy, and at the end of radiotherapy. Mean changes of scores over time were analyzed using a generalized linear mixed model. Results: Of the 50 patients, 34 (68%) participated in 4 sessions of art therapy. Generalized linear mixed models testing for the effect of time on mean score changes showed no significant changes in scores from baseline for the BFI and FACIT-F. The mean BFI score and FACIT-F total score changed from 3.1 to 2.7 and from 110.7 to 109.2, respectively. Art therapy based on the appreciation of famous paintings led to increases in self-esteem by increasing self-realization and forming social relationships. Conclusion: Fatigue and QoL in cancer patients with art therapy do not deteriorate during a period of radiotherapy. Despite the single-arm small number of participants and pilot design, this study provides a strong initial demonstration that art therapy of appreciation for famous painting is worthy of further study for fatigue and QoL improvement. Further, it can play an important role in routine practice in cancer patients during radiotherapy. PMID:27306778

    To test the "27 club" hypothesis that famous musicians are at an increased risk of death at age 27. Design Cohort study using survival analysis with age as a time dependent exposure. Comparison was primarily made within musicians, and secondarily relative to the general UK population. The popular music scene from a UK perspective. Musicians (solo artists and band members) who had a number one album in the UK between 1956 and 2007 (n = 1046 musicians, with 71 deaths, 7%). Risk of death by age of musician, accounting for time dependent study entry and the number of musicians at risk. Risk was estimated using a flexible spline which would allow a bump at age 27 to appear. We identified three deaths at age 27 amongst 522 musicians at risk, giving a rate of 0.57 deaths per 100 musician years. Similar death rates were observed at ages 25 (rate = 0.56) and 32 (0.54). There was no peak in risk around age 27, but the risk of death for famous musicians throughout their 20s and 30s was two to three times higher than the general UK population. The 27 club is unlikely to be a real phenomenon. Fame may increase the risk of death among musicians, but this risk is not limited to age 27.

  8. There is grandeur in this view of Newton: Charles Darwin, Isaac Newton and Victorian conceptions of scientific virtue.

    Bellon, Richard

    2014-01-01

    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.

  9. Enlarging the bounds of moral philosophy: Why did Isaac Newton conclude the Opticks the way he did?

    2017-01-01

    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.

    Madagascar was only ever of secondary importance to Indonesians compared with mineral-rich Africa. But for centuries the Austronesian-speaking, Afro-Indonesian people of Madagascar maintained regular contact with the mainland giving rise to mixed societies, particularly in the Mozambique-Zimbabwe region. He believes the ancient Zimbabwe culture was in several ways linked with that of Madagascar, and that the vast ruin area of Nyanga was also connected. These cross-channel associations were gradually eclipsed by the domination of Arab-Shirazi colonisation down the East African Coast. There is a wealth of evidence that Indonesians rounded the Cape and sailed to West Africa. Several elements of Nigerian culture generally attributed to East-West overland movements or trans-Saharan Arab traders, are more likely to have reached the lower Niger regions by sea from Indonesia. Among these was the technology enabling the iconic ‘bronze’ artwork for which Nigeria is famous.

    World War I advanced the development of aviation from the concept of flight to the use of aircraft on the battlefield. Fighter planes advanced technologically as the war progressed. Fighter pilot aces Francesco Baracca and Manfred von Richthofen (the Red Baron) were two of the most famous pilots of this time period. These courageous fighter aces skillfully maneuvered their SPAD and Albatros planes, respectively, while battling enemies and scoring aerial victories that contributed to the course of the war. The media thrilled the public with their depictions of the heroic feats of fighter pilots such as Baracca and the Red Baron. Despite their aerial prowess, both pilots would eventually be shot down in combat. Although the accounts of their deaths are debated, it is undeniable that both were victims of traumatic head injury.

  12. Sharing one biographical detail elicits priming between famous names: Empirical and computational approaches

    Full Text Available In this paper three experiments and corresponding model simulations are reported that investigate the priming of famous name recognition in order to explore the structure of the part of the semantic system dealing with people. Consistent with empirical findings, novel computational simulations using Burton et al.'s interactive activation and competition model point to a conceptual distinction between how priming is initiated in single- and double-familiarity tasks, indicating that priming should be weaker or non-existent for the single-familiarity task. Experiment One demonstrates that, within a double-familiarity framework using famous names, categorial and associative priming are reliable effects. Pushing the model to the limit, it predicts that pairs of celebrities who are neither associatively- nor categorially-related but who share single biographical features, both died in a car crash for example, should prime each other. Experiment Two investigated this in a double familiarity task but the effect was not observed. We therefore simulated and realized a pairwise learning task that was conceptually similar to the double-familiarity decision task but allowed to strengthen the underlying connections. Priming based on a single biographical feature could be found both in simulations and the experiment. The effect was not due to visual or name similarity which were controlled for and participants did not report using the biographical links between the people to learn the pairs. The results are interpreted to lend further support to structural models of the memory for persons. Furthermore, the results are consistent with the idea that episodic features known about people are stored in semantic memory and are automatically activated when encountering that person.

  13. Achilles' death: anatomical considerations regarding the most famous trauma of the Trojan War.

    In Greek mythology, Achilles was a hero of the Trojan War, the central character and greatest warrior of Homer's Iliad. As Achilles died because of a small wound on his heel, the term "Achilles' heel" has come to mean a person's principal weakness. But is the human heel a really vulnerable part of our body? Could a non-poisonous arrow have caused Achilles' death? Should an arrow be necessarily poisonous in order to cause a lethal heel would? The purpose of this effort is to explain, from an anatomic point of view, how Achilles heel wounding could have led to his death. The Achilles tendon is the strongest, largest and thickest tendon in the human body and plays an important role in the biomechanics of the lower extremity. The blood supply of the tendon is from the peroneal and posterior tibial arteries. It is quite likely that the arrow which killed Achilles was poisoned. This supposition could be of course enough to cause his death. In case the arrow was not poisoned a rupture of the posterior tibial artery by the arrow could have caused a bleeding, but it seems unlikely for such a bleeding to be lethal. Moreover, a combination of these two theories could have also taken place, i.e. a poisoned arrow traumatizing the posterior tibial artery and hence causing rapid diffusion of the poison as well as bleeding. Furthermore, infectious and/or immunologic bases regarding Achilles' death could be considered. In our opinion, a poisoned arrow was probably the crucial factor leading to the famous inglorious death of this famous glorious Homeric hero.

  14. The lead-poisoned genius: saturnism in famous artists across five centuries.

    2013-01-01

    Lead poisoning (saturnism) has been present throughout the history of mankind. In addition to possible ingestion from contaminated food, one of the most important ways in which poisoning caused morbid processes was by occupational exposure. This exposition was pandemic in the Roman Empire, and it has been claimed that it contributed to its fall, but it also caused numerous epidemics in Western countries until the nineteenth century. In the case of artists, and since the Renaissance period, this toxicity has been called painter's colic or painter's madness. The latter term is partly due to the mental disorders displayed by some of the great masters, including Michelangelo and Caravaggio, although it was long recognized that even house and industrial painters were prone to the disorder. This chapter examines the historical evidence of recognition of such toxicity and discusses the controversies raised by the possibility of professional lead poisoning in great artists. In addition to those mentioned above, many other artists across several centuries will be discussed, some being Rubens, Goya, Fortuny, Van Gogh, Renoir, Dufy, Klee, Frida Kahlo, and Portinari. This chapter also briefly mentions the possibility of lead poisoning in two famous composers: Beethoven and Handel. Whether suffering from lead poisoning or not, about which we cannot always be sure, we should still highlight and admire such geniuses fighting their disorders to bequeath us their immortals works. © 2013 Elsevier B.V.

    In 1919, astronomers performed an experiment during a solar eclipse, attempting to measure the deflection of stars near the sun, in order to verify Einstein's theory of general relativity. The experiment was very difficult and the results were marginal, but the success made Albert Einstein famous around the world. Astronomers last repeated the experiment in 1973, achieving an error of 11%. In 2017, using amateur equipment and modern technology, I plan to repeat the experiment and achieve a 1% error. The best available star catalog will be used for star positions. Corrections for optical distortion and atmospheric refraction are better than 0.01 arcsec. During totality, I expect 7 or 8 measurable stars down to magnitude 9.5, based on analysis of previous eclipse measurements taken by amateurs. Reference images, taken near the sun during totality, will be used for precise calibration. Preliminary test runs performed during twilight in April 2016 and April 2017 can accurately simulate the sky conditions during totality, providing an accurate estimate of the final uncertainty.

    Full Text Available Previous experiments have examined exposure to anti-identities (faces that possess traits opposite to an identity through a population average, finding that exposure to antifaces enhances recognition of the plus-identity images. Here we examine adaptation to antifaces using famous female celebrities. We demonstrate: that exposure to a color and shape transformed antiface of a celebrity increases the likelihood of perceiving the identity from which the antiface was manufactured in a composite face and that the effect shows size invariance (Experiment 1, equivalent effects are seen in internet and laboratory based studies (Experiment 2, adaptation to shape-only antifaces has stronger effects on identity recognition than adaptation to color-only antifaces (Experiment 3, and exposure to male versions of the antifaces does not influence the perception of female’s faces (Experiment 4. Across these studies we found an effect of order where aftereffects were more pronounced in early than later trials. Overall, our studies delineate several aspects of identity aftereffects and support the proposal that identity is coded relative to other faces with special reference to a relatively sex-specific mean face representation.

    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

    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.

    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.

    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.

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

    1975-11-01

    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)

    The current modes of experience inheritance from famous specialists in traditional Chinese medicine (TCM) include master and disciple, literature review, clinical-epidemiology-based clinical research observation, and analysis and data mining via computer and database technologies. Each mode has its advantages and disadvantages. However, a scientific and instructive experience inheritance mode has not been developed. The advent of the big data era as well as the formation and practice accumulation of the TCM clinical research paradigm in the real world have provided new perspectives, techniques, and methods for inheriting experience from famous TCM specialists. Through continuous exploration and practice, the research group proposes the innovation research mode based on the real-world TCM clinical research paradigm, which involves the inheritance and innovation of the existing modes. This mode is formulated in line with its own development regularity of TCM and is expected to become the main mode of experience inheritance in the clinical field.

    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.

    It is a matter of considerable debate whether attention to initial stimulus presentations is required for repetition-related neural modulations to occur. Recently, it has been assumed that faces are particularly hard to ignore, and can capture attention in a reflexive manner. In line with this idea, electrophysiological evidence for long-term repetition effects of unattended famous faces has been reported. The present study investigated influences of attention to prime faces on short-term repetition effects in event-related potentials (ERPs). We manipulated attention to short (200 ms) prime presentations (S1) of task-irrelevant famous faces according to Lavie's Perceptual Load Theory. Participants attended to letter strings superimposed on face images, and identified target letters "X" vs. "N" embedded in strings of either 6 different (high load) or 6 identical (low load) letters. Letter identification was followed by probe presentations (S2), which were either repetitions of S1 faces, new famous faces, or infrequent butterflies, to which participants responded. Our ERP data revealed repetition effects in terms of an N250r at occipito-temporal regions, suggesting priming of face identification processes, and in terms of an N400 at the vertex, suggesting semantic priming. Crucially, the magnitude of these effects was unaffected by perceptual load at S1 presentation. This indicates that task-irrelevant face processing is remarkably preserved even in a demanding letter detection task, supporting recent notions of face-specific attentional resources.

    Reports of postamputation pain and problems linked to phantom limbs have increased in recent years, particularly in relation to war-related amputations. These problems are still poorly understood and are considered rather mysterious, and they are difficult to treat. In addition, they may shed light on brain physiology and neuropsychology. Functional neuroimaging techniques now enable us to better understand their pathophysiology and to consider new rehabilitation techniques. Several artists have suffered from postamputation complications and this has influenced not only their personal life but also their artistic work. Paul Wittgenstein (1887-1961), a pianist whose right arm was amputated during the First World War, became a famous left-handed concert performer. His case provides insight into Post-World War I musical and political history. More specifically, the impact on the artistic life of this pianist illustrates various postamputation complications, such as phantom limb, stump pain, and especially moving phantom. The phantom movements of his right hand helped him develop the dexterity of his left hand. Wittgenstein played piano works that were written especially for him (the most famous being Ravel's Concerto for the Left Hand) and composed some of his own. Additionally, several famous composers had previously written for the left hand. © 2015 Elsevier B.V. All rights reserved.

    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.

    2010-01-01

    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.

  13. The Secrets of the Nearest Starburst Cluster. I. Very Large Telescope/ISAAC Photometry of NGC 3603

    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

    Differences in classical and non-classical singing are due primarily to aesthetic style requirements. The head position can affect the sound quality. This study aimed at comparing the head position for famous classical and non-classical male singers performing high notes. Images of 39 Western classical and 34 non-classical male singers during live performances were obtained from YouTube. Ten raters evaluated the frontal rotational head position (depression versus elevation) and transverse head position (retraction versus protraction) visually using a visual analogue scale. The results showed a significant difference for frontal rotational head position. Most non-classical singers in the sample elevated their heads for high notes while the classical singers were observed to keep it around the neutral position. This difference may be attributed to different singing techniques and phonatory system adjustments utilized by each group.

    The four studies reported here sought to explore the nature of the construct of mind-mindedness. In Study 1, involving 37 mothers of 5- to 8-year-old children, mothers' verbal mind-minded descriptions of their children were positively correlated with their mind-minded descriptions of their current romantic partner. Participants in Studies 2 (N=114), 3 (N=173), and 4 (N=153) were young adults who provided written descriptions of: a close friend and their current romantic partner (Study 2); two specified famous people, two works of art, and a close friend (Study 3); a specified famous person, a famous person of the participant's choice, and a close friend (Study 4). Study 2 obtained paper-and-pen written descriptions, whereas participants completed descriptions in electronic format in Studies 3 and 4. Mind-minded descriptions of friends and partners were positively correlated, but there was no relation between mind-minded descriptions of a friend and the tendency to describe famous people or works of art in mind-minded terms. Levels of mind-mindedness were higher in descriptions of friends compared with descriptions of famous people or works of art. Administration format was unrelated to individuals' mind-mindedness scores. The results suggest that mind-mindedness is a facet of personal relationships rather than a trait-like quality.

    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.

    Full Text Available Traditional Chinese medicine (TCM formula has been playing a very important role in health protection and disease control for thousands of years. Guided by TCM syndrome theories, formula are designed to contain a combination of various kinds of crude drugs that, when combined, will achieve synergistic efficacy. However, the precise mechanism of synergistic action remains poorly understood. One example is a famous TCM formula Yinchenhao Tang (YCHT, whose efficacy in treating hepatic injury (HI and Jaundice syndrome, has recently been well established as a case study. We also conducted a systematic analysis of synergistic effects of the principal compound using biochemistry, pharmacokinetics and systems biology, to explore the key molecular mechanisms. We had found that the three component (6,7-dimethylesculetin (D, geniposide (G, and rhein (R combination exerts a more robust synergistic effect than any one or two of the three individual compounds by hitting multiple targets. They can regulate molecular networks through activating both intrinsic and extrinsic pathways to synergistically cause intensified therapeutic effects. This paper provides an overview of the recent and potential developments of chemical fingerprinting coupled with systems biology advancing drug discovery towards more agile development of targeted combination therapies for the YCHT.

    Full Text Available This document presents the history of how the fame and reputation of the most representative Toluca sausages was constructed from its beginnings to the present day. The document begins explaining the concept of foods with differentiated quality, especially meat products are. Subsequently, the way in which the pork arrived to Mexico and how it was adapted to the Toluca Valley and its implications. After, the explanation on how the production of this meat product, especially chorizo, made Toluca a famous city. Next, unique characteristics of the sausage including type of ingredients, morphology of the product, kinds and varieties are explained. Finally, a reflection is done on the importance of value traditional meat products from an integral perspective. It is concluded that chorizo toluqueño is something more than a food or a sausage, being a fundamental element of Toluca gastronomic heritage of the territory and a specific know-how that has been passed from generation to generation, and that must be revalued.

  10. X-ray microdiffraction on a small piece of skin of the world-famous 'OETZI' (Tyrolean mummified glacier man)

    2002-01-01

    Full text: Recently we performed microdiffraction measurements on a small piece of skin (2 mm x 2 mm) of the world-famous 'Oetzi' which is one of the best preserved mummified humans ever discovered (EDWARDS et al., 1996). He has been found in a glacial field in the Tyrolean Oetztaler Alps between Austria and Italy in 1991. His age is estimated to about 5300 years. An interesting mineralogical detail of the Iceman is the growth of the mineral vivianite Fe 3 (PO 4 ) 2 .8H 2 O on the skin in contact with the surrounding weathered rocks. Vivianite is not uncommon in connection with mummies from bogs (anaerobic, non oxidizing conditions); in the case of the Iceman this seems to be the first report of vivianite from mummified humans in glacier environment (TESSADRI et al., 1996). Measurements have been performed using the Bruker AXS D8 Discover with GADDS fitted with the HI-STAR area detector. This system allows the identification and characterisation of smallest phase amounts (a few micrograms in the present case) in the shortest time possible. The blue-coloured vivianite is not continuously dispersed over the skin of 'Oetzi'; it is concentrated in form of visible particles of microscopic dimensions. With the help of the laser-video-microscope of the GADDS these particles can be recognized and precisely adjusted for microdiffraction measurements with high local resolution. Unlikely to former powder measurements with conventional diffractometers we were able to detect much more diffraction lines than the strongest reflections of vivianite. The given results impressively demonstrate the efficiency and capability of the GADDS for the phase identification in micron regions even under unpropitious conditions (weak line intensities, high background radiation).

    Paull, J D

    2013-07-01

    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.

    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

    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.

    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

    We analyzed, U, Th and 230 Th/ 232 Th activity ratios for a few tholeiites from the Mid-Atlantic Ridge FAMOUS zone at 36 0 50'N. The results show a fairly wider scatter for both Th/U and ( 230 Th/ 232 Th) ratios. Seawater contamination appears to be responsible for this scatter and, for the uranium, produces an increase in content yielding a ( 234 U/ 238 U) ratio greater than 1 and, for the Th, an increase of the ( 230 Th/ 232 Th) ratio which is a very sensitive indicator for contamination. Also, the latter often is selective: U, Th and Sr are not affected in the same manner. When discarding all data for contaminated samples, the FAMOUS zone appears to be very homogeneous with a Th/U ratio value of 3.05 and a ( 230 Th/ 232 Th) ratio value of 1.24. Comparison with other active volcanic areas reveals a negative correlation between ( 230 Th/ 232 Th) and 87 Sr/ 86 Sr ratios for present lavas which is indicative of a consistency in Th-U and Rb-Sr fractionation in the source regions of these magmas. The Th isotopic geochemistry can thus provide useful information for the study of present volcanism, information as valuable as that from Sr, Pb or Nd isotopes. (orig.)

    Deficits in face processing have been described in the behavioral variant of fronto-temporal dementia (bvFTD), primarily regarding the recognition of facial expressions. Less is known about face shape and face identity processing. Here we used a hierarchical strategy targeting face shape and face identity recognition in bvFTD and matched healthy controls. Participants performed 3 psychophysical experiments targeting face shape detection (Experiment 1), unfamiliar face identity matching (Experiment 2), familiarity categorization and famous face-name matching (Experiment 3). The results revealed group differences only in Experiment 3, with a deficit in the bvFTD group for both familiarity categorization and famous face-name matching. Voxel-based morphometry regression analyses in the bvFTD group revealed an association between grey matter volume of the left ventral anterior temporal lobe and familiarity recognition, while face-name matching correlated with grey matter volume of the bilateral ventral anterior temporal lobes. Subsequently, we quantified familiarity-specific and name-specific recognition deficits as the sum of the celebrities of which respectively only the name or only the familiarity was accurately recognized. Both indices were associated with grey matter volume of the bilateral anterior temporal cortices. These findings extent previous results by documenting the involvement of the left anterior temporal lobe (ATL) in familiarity detection and the right ATL in name recognition deficits in fronto-temporal lobar degeneration.

    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

    The concentrations of 137 Cs in water, sediment and biota at the lower region of the famous river in Saitama prefecture were determined in order to elucidate the radioecology of 137 Cs in limnological ecosystems. 137 Cs concentration in water was 0.10 mBq/l. 137 Cs concentrations in sediment, shellfish, Sinotaia quadratus historica (mean for 2 detectable samples), and fish, Carassius auratus cuvieri (mean for 2 detectable samples), were about 6200, 840 and 320 times higher than the concentration of the water, respectively. But 137 Cs radioactivity in the crustacea, Procambarus clarki, was significantly not detected. So, 137 Cs transfer mechanism in the limnological ecosystems was indicated in part. (author)

    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.

    Full Text Available Tourette's syndrome (TS is defined as a disorder characterized by multiple motor tics and at least one vocal tic that have lasted for not less than one year. It is a relatively complex neurobehavioral disorder, in which patients may present with coexistent attention deficit hyperactivity disorder, obsessive-compulsive disorder or other behavioral comorbidities. The musical genius Wolfgang Amadeus Mozart (1756-1791 and the rock star Kurt Cobain (1967-1994 may both have suffered from TS, and some contemporary musicians have had their clinical condition confirmed as TS. Our hypothetical diagnosis of TS in Mozart and Cobain is based on the presence of tics and psychiatric comorbidities. In contemporary musicians, such as Michael Wolff, Nick Van Bloss and James Durbin, TS has often only been diagnosed after a considerable delay. This delay in diagnosis and the controversies surrounding the clinical case of Mozart show how difficult a confirmatory diagnosis of this complex disease is.

  9. The Hidden History of a Famous Drug: Tracing the Medical and Public Acculturation of Peruvian Bark in Early Modern Western Europe (c. 1650-1720).

    Klein, Wouter; Pieters, Toine

    2016-10-01

    The history of the introduction of exotic therapeutic drugs in early modern Europe is usually rife with legend and obscurity and Peruvian bark is a case in point. The famous antimalarial drug entered the European medical market around 1640, yet it took decades before the bark was firmly established in pharmaceutical practice. This article argues that the history of Peruvian bark can only be understood as the interplay of its trajectories in science, commerce, and society. Modern research has mostly focused on the first of these, largely due to the abundance of medico-historical data. While appreciating these findings, this article proposes to integrate the medical trajectory in a richer narrative, by drawing particular attention to the acculturation of the bark in commerce and society. Although the evidence we have for these two trajectories is still sketchy and disproportionate, it can nevertheless help us to make sense of sources that have not yet been an obvious focus of research. Starting from an apparently isolated occurrence of the drug in a letter, this article focuses on Paris as the location where medical and public appreciation of the bark took shape, by exploring several contexts of knowledge circulation and medical practice there. These contexts provide a new window on the early circulation of knowledge of the bark, at a time when its eventual acceptance was by no means certain. © The Author 2016.

    Imperial Porphyry, a famous dimension stone of spectacular purple color, was quarried in the Mons Porphyrites area north of Jabal Dokhan in the Eastern Desert of Egypt, from the beginning of the first until the middle of the fifth century AD. During this period, the valuable material was processed as decorative stone and was used for objects of art, reserved exclusively for the Imperial court of the Roman Empire. Later on, only antique spoils of smaller or bigger size have been re-used for these purposes. The Imperial Porphyry is a porphyritic rock of trachyandesitic to dacitic composition that occurs in the uppermost levels of shallow subvolcanic sill-like intrusions, forming a member of the Dokhan Volcanic Suite. Its purple color is mainly due to dispersed flakes of hematite, resulting from hydrothermal alteration of a dark green Common Porphyry of similar composition, underlying the Imperial Porphyry. Both, the Common Porphyry and the purple Imperial Porphyry', are extensively exposed in the Roman quarries. Contacts between Common and Imperial Porphyry are irregular and gradational. In both rock types, intrusive breccias are frequent, indicating a complex intrusion history. U-Th-Pb zircon geochronology on two samples of Imperial Porphyry and one sample of the Common Porphyry yielded an age range of 609-600 Ma, thus confirming earlier results of radiometric dating. Geochemical evidence indicates that both the Imperial and the Common Porphyry are of medium- to high-K calc-alkaline affinity. The magmas have formed by partial melting of a subduction-modified upper mantle. The subsequent intrusion took place within a highly extended terrane (HET).

    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.

    The concentrations of {sup 137}Cs in water, sediment and biota at the lower region of the famous river in Saitama prefecture were determined in order to elucidate the radioecology of {sup 137}Cs in limnological ecosystems. {sup 137}Cs concentration in water was 0.10 mBq/l. {sup 137}Cs concentrations in sediment, shellfish, Sinotaia quadratus historica (mean for 2 detectable samples), and fish, Carassius auratus cuvieri (mean for 2 detectable samples), were about 6200, 840 and 320 times higher than the concentration of the water, respectively. But {sup 137}Cs radioactivity in the crustacea, Procambarus clarki, was significantly not detected. So, {sup 137}Cs transfer mechanism in the limnological ecosystems was indicated in part. (author).

    2018-03-01

    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.

    Serendipity has always been an attendant to great science. Arno Penzias and Robert Wilson discovered the cosmic background radiation after first mistaking it for the effect of pigeon droppings on their microwave antenna. US spy satellites detected gamma-ray bursts when surveying the sky for evidence of secret Soviet nuclear tests during the Cold War. Satyendra Bose arrived at Bose-Einstein statistics only after discovering that a mathematical error explained the experimental data concerning the photoelectric effect. In the words of science-fiction writer Isaac Asimov, "The most exciting phrase in science is not 'Eureka!', but rather, 'That's funny...'.

    Full Text Available Significance of the findings and scientific generalizations, which were made by the the leading Russian scientist of Korean Studies Natalia Bazhanova, goes far beyond the Korean issues. It is of great interest for both the expert community, and for a wide range of readers. Analysis of the political and economic development of the DPRK allowed Bazhanova highlight the characteristics of authoritarian regimes and non-market economy, and to see how they affect the foreign policy and international relations. Natalia Evgen'evna has made a great contribution to the development of historical science. She was the first who introduced into scientific use unique documents on the history of the Korean War of 1950-1953, allowing to understand the causes, course and consequences of the conflict. Bajanova proved itself as a political scientist, analyzing and forecasting the development of the international situation on the Korean Peninsula, making constructive proposals aimed at resolving the North Korean nuclear problem. The works of Bazhanova dedicated to Russian-Korean relations are very significant. Her conclusions on the current development of relations between our two countries are especially valuable, as well as on international multilateral cooperation in the matter of a Korean settlement. Natalia Evgen'evna was the author of monograph, publicistic books and papers devoted to the many countries of the world, including the United States, France, Italy, China. She put her exceptional talent to the study of these topics. The works of Bazhanova characterized by internal logic, depth and light, have “transparent” style of presentation.

  9. Neurological problems of famous musicians: the classical genre.

    Science.gov (United States)

    Newmark, Jonathan

    2009-08-01

    Neurological histories of great musicians allow for a unique perspective on music physiology. Bedrich Smetana's autobiographical string quartet ends with the musical equivalent of tinnitus in the fourth movement, rendering the youthful and passionate themes of earlier movements moot as the piece ends depicting his ultimately fatal disease, neurosyphilis. Dmitri Shostakovich survived the censorship of Joseph Stalin's apparatchiks but suffered a prolonged form of paralysis attributable to slowly progressive motor neuron disease, although the viola sonata he wrote on his deathbed has become standard repertoire. Glenn Gould was a hypochondriacal pianist with obsessive-compulsive disorder and suspected Asperger syndrome. Vissarion Shebalin and (Ira) Randall Thompson had strokes followed by aphasia without amusia. Domenico Scarlatti provides an example of how even great composers must alter their technical expectations depending upon the skills and body habitus of their chief patrons. The focal dystonia afflicting Leon Fleisher and Gary Graffman catalyzed the discipline of performing arts medicine.

  19. Famous people with Gilles de la Tourette syndrome?

    Science.gov (United States)

    Monaco, Francesco; Servo, Serena; Cavanna, Andrea Eugenio

    2009-12-01

    Virtually no neurologist nor psychiatrist today can be unaware of the diagnosis of Gilles de la Tourette syndrome (GTS). Although the eponymous description by Dr. Georges Gilles de la Tourette was published in 1885, familiarity with this syndrome has been achieved only recently. In this article, the two most renown accounts of exceptional individuals retrospectively diagnosed with GTS are critically analyzed: British lexicographer Samuel Johnson and Austrian musician Wolfgang Amadeus Mozart. In both cases, clinical descriptions have been retrieved from written documents predating Gilles de la Tourette's original publication. The case for Samuel Johnson having GTS is strong, mainly based on Boswell's extensive biographical account. Johnson was reported to have a great range of tics and compulsions, including involuntary utterances, repetitive ejaculations, and echo-phenomena. On the other hand, there is circumstantial evidence that Mozart may have had hyperactivity, restlessness, sudden impulses, odd motor behaviors, echo/palilalia, love of nonsense words, and scatology, the latter being documented in autograph letters ("coprographia"). However, the evidence supporting the core features of GTS, i.e., motor and vocal tics, is rather inconsistent. Thus, GTS seems to be an implausible diagnosis in Mozart's medical history and completely unrelated to his undisputed musical genius.

  20. Positive emotion word use and longevity in famous deceased psychologists.

    Pressman, Sarah D; Cohen, Sheldon

    2012-05-01

    This study examined whether specific types of positive and negative emotional words used in the autobiographies of well-known deceased psychologists were associated with longevity. For each of the 88 psychologists, the percent of emotional words used in writing was calculated and categorized by valence (positive or negative) and arousal (activated [e.g., lively, anxious] or not activated [e.g., calm, drowsy]) based on existing emotion scales and models of emotion categorization. After controlling for sex, year of publication, health (based on disclosed illness in autobiography), native language, and year of birth, the use of more activated positive emotional words (e.g., lively, vigorous, attentive, humorous) was associated with increased longevity. Negative terms (e.g., angry, afraid, drowsy, sluggish) and unactivated positive terms (e.g., peaceful, calm) were not related to longevity. The association of activated positive emotions with longevity was also independent of words indicative of social integration, optimism, and the other affect/activation categories. Results indicate that in writing, not every type of emotion correlates with longevity and that there may be value to considering different categories beyond emotional valence in health relevant outcomes.

Many rich people change their mobile devices, purchase new expensive cars, etc. This paper investigates the effects of three factors including consumer perceived value, sensitivity to social norms and need for uniqueness on consumer’s intention to purchase luxury products based on the theory of planned behavior. The proposed study uses clustering technique and randomly chooses a sample of 250 rich people and distributes a questionnaire among them. The study uses structural equation modeling and the implementation of the proposed model has been executed using LISREL software package. The results indicate the all three factors, consumer perceived value, sensitivity to social norms and need for uniqueness, influence consumer intention to buy luxury goods. In addition, consumer knowledge is a mediator factor between need for uniqueness and purchase intention.

    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.

    2011-10-01

    Currently, the event-related potential (ERP)-based spelling device, often referred to as P300-Speller, is the most commonly used brain-computer interface (BCI) for enhancing communication of patients with impaired speech or motor function. Among numerous improvements, a most central feature has received little attention, namely optimizing the stimulus used for eliciting ERPs. Therefore we compared P300-Speller performance with the standard stimulus (flashing characters) against performance with stimuli known for eliciting particularly strong ERPs due to their psychological salience, i.e. flashing familiar faces transparently superimposed on characters. Our results not only indicate remarkably increased ERPs in response to familiar faces but also improved P300-Speller performance due to a significant reduction of stimulus sequences needed for correct character classification. These findings demonstrate a promising new approach for improving the speed and thus fluency of BCI-enhanced communication with the widely used P300-Speller.

  1. The Einstein file J. Edgar Hoover's secret war against the world's most famous scientist

    CERN Document Server

    Jerome, Fred

    2002-01-01

    From the moment of Einstein's arrival in the U.S. in l933 until his death in l955, J. Edgar Hoover's FBI, with help from several other federal agencies, busied itself collecting "derogatory information" in an effort to undermine Einstein's influence and destroy his prestige. For the first time Fred Jerome tells the story of that anti-Einstein campaign, as well as the story behind it--why and how the campaign originated, and thereby provides the first detailed picture of Einstein's little known political activism. Unlike the popular image of Einstein as an absent-minded, head-in-the-clouds genius, the man was in fact intensely politically active and felt it was his duty to use his world-wide fame shrewdly in the cause of social justice. A passionate pacifist, socialist, internationalist and outspoken critic of racism (Einstein considered racism America's "worst disease"), and personal friend of Paul Robeson and W.E.B. DuBois, Einstein used his immense prestige to denounce McCarthy at the height of his power, ...

  2. Uranium content and fission track ages of some basalts from the FAMOUS area

    Storzer, Dieter; Selo, Madeleine

    1976-01-01

    The uranium contents of basalts from the rift valley in the Atlantic ocean near 37 deg N range between 75 ppb and 450 ppb. The fission track ages of these basalts range between 3x10 3 years and 6x10 5 years. They increase with distance from the axis of the median valley. Therefore, the locus of accretion of new crust seems to be restricted to a relatively narrow zone along the valley floor. In addition, the ages indicate that during the last 10 5 years the rate of accretion has been slower to the west than to the east. This indicates a migration of the active spreading center to the west by at least 1 km. the sea-floor spreading rates are high, up to 9cm/year, near the center of actual magmatic activity. They decrease with distance from the valley axis to 0.7 cm/year at about 2 km in the west respectively 1.5 cm/year at about 4 km in the east

    2009-01-01

    This work used Energy Dispersive X-Ray Fluorescence (EDXRF) and Computed Radiography (CR) to evaluate the general conditions of the painting 'Gioventu' (Eliseu Visconti, 1898), identifying possible problems, areas that revealed signs of previous retouchings and the pigments used by the artist. EDXRF measurements were carried out with a portable system consisting of an X-ray tube Oxford TF3005 with W anode, operating at 25 kV and 100 μA, and a Si-PIN XR-100CR detector from Amptek. Several spectra were obtained in each color, with an acquisition time of 300 s and a beam collimation of 2 mm. The spectra were analyzed using the software QXAS-AXIL (IAEA). The results revealed that the drawings were made over a preparatory layer of lead white. Some pigments identified were: yellow, red and brown ochre; umbra; vermilion; cobalt blue; etc. The experimental setup used in the CR analysis consisted of an Oxford X-ray source, operating at 50 kV and 200 μA, placed at 85 cm from the painting, a GE CR 50P portable computed radiography scanner and a Fuji imaging plate detector. The exposure time was 600 s. The radiographic images revealed that the painting was in a good state of conservation and also a complete composition hidden underneath the visible paint layer.(author)

    2000-01-01

    The Ruland family of German origin played an important role both in Hungarian and European medical history. Being a rather numerous family, and moreover, due to their habit of preferring to give the same first names to their children and because they worked in a relatively short period (ca. between 1550 and 1650), researchers often confuse one Ruland with the other. The present paper based on source-criticism, makes successful attempts to put the genealogy in order, presenting the history of the family, giving detailed biographies of each single Ruland and bringing together the bibliography of their works as well. As a result of her efforts the author puts a new light on the biographical data of the best known Ruland, namely of John David and at the same time she revisits the activity of John Ruland, who lived and worked in Hungary.

  6. An Analysis of the Atmospheric Trajectories of the Famous Meteorite Producing Fireballs

    2010-08-01

    In the present study the modern analytical model of the atmospheric entry (Gritsevich, 2007) is applied to well-known real impacts. These are Pribram, Lost City, Innisfree, and Neuschwanstein meteorite falls. For each of the events preatmospheric mass is calculated using the data of actual observations, by selecting the parameters describing deceleration and ablation of fireballs along the luminous segment of the trajectory. Mathematical model is based on the best fitting of the observational data by the analytical solution of the equations of meteor physics. Other estimations of preatmospheric mass for Pribram, Lost City, Innisfree, and Neuschwanstein fireballs are also presented. The majority of them considerably differs from each other. The greater difference is appreciable between the estimations received by dynamic and photometric methods. In the paper (Ceplecha, ReVelle, 2005) the mixed approach is presented. However, the found terminal mass has been accepted by authors (Ceplecha, ReVelle, 2005) as the given condition. When this study was prepared, the terminal mass has been calculated analytically. And it is exceptionally important, that results have appeared quite close to their real values.

    What about artistic creativity following a cerebral lesion? We studied the case of a prominent right-handed Swedish painter and sculptor who suffered a cerebral hemorrhage at the age of 55 years. The patient displayed a lesion of the left capsular lenticular region, which resulted in a right hemiplegia and sensory loss, with aphasia of the subcortical type. The linguistic impairments recovered well but at 1 year postonset, the right hand was still completely paralyzed. After a period of a few weeks, during which the patient refused to use his nondominant hand, he produced his first left-handed drawing, and by 1 year postonset, he had once again resumed an intensive artistic activity using his nondominant hand. The pictorial works were reviewed by several renowned art specialists: changes of style and even of contents were judged without loss of artistic quality. The result was described as a gain in emotional and artistic intensity. We discuss our observation in the context of the literature and focus on the crucial role of cerebral dominance and hand preference. We conclude that pictorial creativity and language are distinct forms of expressions.

  8. TROUBLING GENDER EQUALITY: REVISITING GENDER EQUALITY WORK IN THE FAMOUS NORDIC MODEL COUNTRIES

    Directory of Open Access Journals (Sweden)

    Charlotta Edström

    2016-06-01

    Full Text Available This article concerns gender equality work, that is, those educational and workplace activities that involve the promotion of gender equality. It is based on research conducted in Sweden and Finland, and focuses on the period during which the public sector has become more market-oriented and project-based all over the Nordic countries. The consequences of this development on gender equality work have not yet been thoroughly analysed. Our joint empirical analysis is based on discourse-analytic methodology and two previous empirical studies. By analysing interviews conducted with people involved in gender equality work, this article emphasises the effects of market-oriented and project-based gender equality work in education and working life in Sweden and in Finland. The findings highlight an alliance between projectisation and heteronormativity that acts to regulate how gender equality ought to be talked about in order for its issues to be heard. A persistently constructed ‘remedy’ to ‘the gender equality problem’ is that girls and women are positioned as ‘needing’ to change more than boys and men, by adopting more traditionally ‘masculine manners’ and choosing to work in more ‘masculine sectors’. The findings also show that the constitutive forces of these discourses provide little leeway for critical perspectives.

    Rowland, David R.

    2004-09-01

    Nelson (2003 Eur. J. Phys. 24 379) recently claimed on logical grounds that Einstein's train and embankment thought experiment cannot be used to prove the relativity of simultaneity prior to knowledge of the Lorentz transformations as it is purported to do. It is argued in this comment that Nelson's claim is based on premises which are incorrect, thus invalidating his conclusions. It is also argued that Nelson's article furnishes a 'proof by contradiction' of the desired result, thus also invalidating his claim.

    2016-01-01

    Hibiscus sabdariffa L. is a plant native to tropical Africa and intensively cultivated in Sudan. Its calyces are widely consumed with many uses in Sudanese folk medicine. The dried calyces of H. sabdariffa were subjected to soak in 80% v/v methanol to get the methanolic extract, which was tested against five Gram-negative and three Gram-positive referenced bacterial strains using disc diffusion method. Selected bioactive phytochemical compounds were also investigated using qualitative methods. The results of the antibacterial test indicate that the methanol extract of H. sabdariffa calyces contained effective antibacterial agent(s), revealed a considerable zone of inhibition against all tested Gram-negative and Gram-positive bacteria, and it was a competitor to gentamicin and greatly higher than penicillin which showed weak or no effect. The results of current investigation support the folk medicine application of this plant against different microbial ailments and suggest it as a promising source for new antibacterial agents.

    Full Text Available The theme of the article is illumination of the biography of the graduate of Imperial Novorossiysk University Vasyl Petrovich Gutor. The main task of article – to expand and aggregate biographic information and highlight career of V. P. Gutor. On one concrete example to show how graduates of university proved and realized in various fields of activity, sometimes far from the education got at classical university. V. P. Gutor known as the musician-cellist, he has developed the basic principles of teaching music and has made the significant contribution to musical education of broad masses of the population, was the author methodical and critiques, one of the founders of classical music education. Gutor V. P. was a founder, the director of music schools in Chisinau and Elisavetgrad, and then the teacher and professor of the Odessa conservatory. In article is special attention paid to the Odessa period of his activity. However, unfortunately, it is not enough data on this period. The main finding of the work is that, having tracked a course of life of one specific person, it is possible to tell with confidence that else many destinies of the people carrying a  proud rank of graduates of Imperial Novorossiysk University remain unknown for modern scientists and researchers. The research findings have the practical value for all who are interested in music history, musical pedagogics and history of music in Odessa in the first half of the 20th century.

    The article traces the sources of the three most widespread quotations attributed to Freud "What does Woman want?", "To love and to work" (summarizing what a psychological healthy person should be able to do well), and "Sometimes a cigar is just a cigar". The first could have been spoken by Freud pretty much as we have it. The second was possibly said by Freud, in some form vaguely resembling the currently cited version. The third most probably did not come from him in any form.

    2016-01-01

    This review article is a continuation of the paper "Hepatitis B core particles as a universal display model: a structure-function basis for development" written by Pumpens P. and Grens E., ordered by Professor Lev Kisselev and published in FEBS Letters, 1999, 442, 1-6. The past 17 years have strengthened the paper's finding that the human hepatitis B virus core protein, along with other Hepadnaviridae family member core proteins, is a mysterious, multifunctional protein. The core gene of the Hepadnaviridae genome encodes five partially collinear proteins. The most important of these is the HBV core protein p21, or HBc. It can self-assemble by forming viral HBc particles, but also plays a crucial role in the regulation of viral replication. Since 1986, the HBc protein has been one of the first and the most successful tools of the virus-like particle (VLP) technology. Later, the woodchuck hepatitis virus core protein (WHc) was also used as a VLP carrier. The Hepadnaviridae core proteins remain favourite VLP candidates for the knowledge-based design of future vaccines, gene therapy vectors, specifically targeted nanocontainers, and other modern nanotechnological tools for prospective medical use.

  20. CONSIDERATIONS REGARDING THE PROTECTION OF FAMOUS MARKS IN E-COMMERCE

    Directory of Open Access Journals (Sweden)

    Georgeta Valeria Sabau

    2013-09-01

    Full Text Available Although the benefits of e-commerce are remarkable both for companies and for the consumers and the society, the context of the virtual revolution creates many opportunities to infringe the international and european legal provisions concerning the protection of trademarks. Globally, the protection of notorious trademarks is presently matchless and laborious enough so that the problematic in focus constitutes a long subject of analysis and discussion. The goals and the purpose of the research focus upon the analysis of the doctrine and jurisprudence of the European Court of Justice. Approaching these goals both logically and historically with international, european and judicial practice regulations, the authors concluded that these do not offer a clear answer to the question whether using the trademark of a competitor as a search engine keyword will constitute an infringement of the trademark, a fact that seems to be needing evaluation for each case.

    2000-01-01

    Nephrology is a newborn speciality compared to the other medical specialities. However, the study of the urinary tract's physiology and pathology had begun simultaneously with the birth of medicine. The scientific revolution of the renaissance and enlightenment eras caused an intense contestation of earlier theories and methods as if all knowledge had evolved suddenly from parthenogenesis after the dark (?) medieval years and human intellect suddenly exploded to huge intelligence quotients after the 15th century while before that humans were mentally deprived. Indeed most of the scientific knowledge did evolve impressively during renaissance and enlightenment years but not through parthenogenesis. Some observations, discoveries and inventions of this era were actually reobservations, rediscoveries and reinventions. Such an example is that of the experiments of Sanctorius Santorii of the 16th century AD and of Erasistratus of the 3rd century BC. Sanctorius and Erasistratus carried out an experiment with the same basic principles, similar methodology and proportional results with an almost 2000 years lag phase. With our paper we wish to give credit to earlier researchers of physiological and medical knowledge who, despite the lack of technological support, often concluded in extremely accurate observations.

  13. The origin of the turtle body plan: bridging a famous morphological gap.

    Science.gov (United States)

    Lee, M S

    1993-09-24

    A restudy of pareiasaurs reveals that these primitive reptiles are the nearest relatives of turtles. The two groups share numerous derived characters, such as a reduced presacral count, an acromion process, and a trochanter major, which are absent in other basal amniotes. Many traits long thought specific to chelonians also occur in pareiasaurs and must have evolved before the distinctive turtle shell appeared. Evidence uniting captorhinid or procolophonoids with turtles is shown to be weak. The phylogeny proposed here also suggests that certain features of the earliest turtle (Proganochelys) that have been interpreted as specializations, such as the large supratemporal and robust metacarpals, are primitive for turtles. In pareiasaurs, the osteoderms represent the precursors of the chelonian shell and the morphology of the anterior region is consistent with the idea that the shoulder girdle in turtles has migrated posteriorly into the rib cage.

    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.

  15. A history of mathematics

    "Boyer and Merzbach distill thousands of years of mathematics into this fascinating chronicle. From the Greeks to Godel, the mathematics is brilliant; the cast of characters is distinguished; the ebb and flow of ideas is everywhere evident. And, while tracing the development of European mathematics, the authors do not overlook the contributions of Chinese, Indian, and Arabic civilizations. Without doubt, this is--and will long remain--a classic one-volume history of mathematics and mathematicians who create it." --William Dunham Author, Journey Through Genius, The Great Theorems of Mathematics "When we read a book like A History of Mathematics, we get the picture of a mounting structure, ever taller and broader and more beautiful and magnificent--and with a foundation, moreover, that is as untainted and as functional now as it was when Thales worked out the first geometrical theorems nearly 26 centuries ago." --From the Foreword by Isaac Asimov "One of the most useful and comprehensive general introductions t...

  16. The Future of the New Media in the Communication of Science

    2014-03-01

    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.

  17. AIonAI: a humanitarian law of artificial intelligence and robotics.

    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.

    Cognitive skills are the emergent property of distributed neural networks. The distributed nature of these networks does not necessarily imply a lack of specialization of the individual brain structures involved. However, it remains questionable whether discrete aspects of high-level behavior might be the result of localized brain activity of individual nodes within such networks. The phonological loop of working memory, with its simplicity, seems ideally suited for testing this possibility. Central to the development of the phonological loop model has been the description of patients with focal lesions and specific deficits. As much as the detailed description of their behavior has served to refine the phonological loop model, a classical anatomoclinical correlation approach with such cases falls short in telling whether the observed behavior is based on the functions of a neural system resembling that seen in normal subjects challenged with phonological loop tasks or whether different systems have taken over. This is a crucial issue for the cross correlation of normal cognition, normal physiology, and cognitive neuropsychology. Here we describe the functional anatomical patterns of JB, a historical patient originally described by Warrington et al. (1971), a patient with a left temporo-parietal lesion and selective short phonological store deficit. JB was studied with the H 2 15 O PET activation technique during a rhyming task, which primarily depends on the rehearsal system of the phonological loop. No residual function was observed in the left temporo-parietal junction, a region previously associated with the phonological buffer of working memory. However, Broca's area, the major counterpart of the rehearsal system, was the major site of activation during the rhyming task. Specific and autonomous activation of Broca's area in the absence of afferent inputs from the other major anatomical component of the phonological loop shows that a certain degree of functional independence or modularity exists in this distributed anatomical-cognitive system.

    When Mark McGwire broke Roger Maris's home run record in September of 1998, he was instantly declared an American hero and held up as a positive role model for teenagers and young adults. The extensive media attention focused on McGwire made the general public aware of his use of a muscle-building dietary supplement, Androstenedione. It also increased the public's awareness of McGwire's public service to prevent child abuse. The present research assesses audience involvement with McGwire through parasocial interaction and identification, and the effects of that involvement on audience knowledge of and attitudes toward Androstenedione and child abuse prevention. Results indicate parasocial interaction with an athlete regarded as a public role model likely leads to audience identification with that person, which in turn promotes certain attitudes and beliefs. In this case, parasocial interaction and identification with Mark McGwire was strongly associated with knowledge of Androstenedione, intended use of the supplement, and concern for child abuse. Implications of this research for featuring celebrities in health communication campaigns are discussed.

  3. The dark knight : Sir Thomas Tait and the rise and fall of New Brunswick's famous coalfields

    Energy Technology Data Exchange (ETDEWEB)

    Woodford, G.

    2010-03-15

    Industrial coal mining in New Brunswick began in the early 1900s. In 1913, a former Canadian Pacific Railway (CPR) manager, Sir Thomas Tait, learned of underexploited coalfields around Grand Lake and negotiated the best coal assets from locals. He used his CPR connections to secure a large government grant to finish an important 50-kilometre railway link between Minto and Fredericton. He kept the coal assets for himself and formed the Minto Coal Company and landed 2 prime contracts to supply coal to a nearby cotton mill and to CPR. This article highlighted Tait's disreputable approach to labour relations. Despite lucrative contracts to Minto Coal during World War 1, Tait did not share the profits with his miners. This coal mining period in New Brunswick was characterized by union busting, evictions from dire company housing, arbitrary pay cuts, strikes and increasingly unsafe conditions in the mines. Two royal commissions were called to look into matters, but the province had no legislation to enforce their many recommendations. However, the government finally passed legislation when in 1932, 5 people died trying to rescue boys who were poisoned while playing in an abandoned mine shaft. That same year, 14 miners were disabled and 2 men killed in accidents at Minto Coal. Legislation forced mines to reduce work hours and improve safety. Women and children were barred from mining. When Tait refused to reduce work hours the miners went on strike again. After a critical situation in 1937 when 1000 miner and 11 colliers walked out, things gradually improved for both the miners and mine owners. New technology in the 1940s led to greater production, safety and profits. In 1944, Minto Coal donated land and money to build the town's first hospital. Credit for this philanthropy did not go to Thomas Tait, who died in 1940.

    Chen Jingrun (1933-1996), perhaps the most prodigious mathematician of his time, focused on the field of analytical number theory. His work on Waring's problem, Legendre's conjecture, and Goldbach's conjecture led to progress in analytical number theory in the form of "Chen's Theorem," which he published in 1966 and 1973. His early life was ravaged by the Second Sino-Japanese War and the Chinese Cultural Revolution. On the verge of solving Goldbach's conjecture in 1984, Chen was struck by a bicyclist while also bicycling and suffered severe brain trauma. During his hospitalization, he was also found to have Parkinson's disease. Chen suffered another serious brain concussion after a fall only a few months after recovering from the bicycle crash. With significant deficits, he remained hospitalized for several years without making progress while receiving modern Western medical therapies. In 1988 traditional Chinese medicine experts were called in to assist with his treatment. After a year of acupuncture and oxygen therapy, Chen could control his basic bowel and bladder functions, he could walk slowly, and his swallowing and speech improved. When Chen was unable to produce complex work or finish his final work on Goldbach's conjecture, his mathematical pursuits were taken up vigorously by his dedicated students. He was able to publish Youth Math, a mathematics book that became an inspiration in Chinese education. Although he died in 1996 at the age of 63 after surviving brutal political repression, being deprived of neurological function at the very peak of his genius, and having to be supported by his wife, Chen ironically became a symbol of dedication, perseverance, and motivation to his students and associates, to Chinese youth, to a nation, and to mathematicians and scientists worldwide.

    Tourette's syndrome is a clinical condition characterized by multiple motor tics and vocal tics which occurs in the age range 5-25 years and the intensity of the symptoms changes with time. It is felt that at least two remarkable personalities namely, Dr. Samuel Johnson from England, a man of letters and the compiler of the first ever English dictionary, and Wolfgang Amadeus Mozart from Austria, one of the greatest musical genius of all time, possibly suffered from this condition. Tourette's syndrome is often described as the classical borderzone between neurology and psychiatry and every neurologist wonders at the curious and fascinating clinical features of this condition. It seems that at least two remarkable personalities, Dr. Samuel Johnson, a man of letters and the first person to compile an English dictionary, and Wolfgang Amadeus Mozart, arguably the most creative musical composer of all time, were possibly afflicted with this condition.

    Gregorio Cárdenas Hernández was Mexico's most infamous serial killer. After he confessed to killing four young women and burying them behind his home, he became the darling of the crime pages and criminological experts alike, and his case provoked a lively debate over the reinstatement of the death penalty in congress. The following essay uses his story, the policy debates it provoked, and his broader institutional odyssey in La Castañeda mental asylum (1943–1947) and Lecumberri prison (1948–1976) to explore how issues that affected Mexicans across the social spectrum were discussed and settled in a political system that was neither a dictatorship nor a democracy.

    2017-09-01

    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. This study supports current dietary recommendations which emphasize the consumption of vegetables, nut and pulses, although the effect sizes were small.

    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.

    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.

    This research interrogates Bennie van der Walt’s third way as a solution for the “divided soul” of the African people - a divided soul that creates a false dilemma. This division is the creation of political colonialism and neo-colonialism, which impacts negatively on the African socio-economic and political structure. The myth of the superiority of Western culture propagates this vice. Van der Walt’s clarification of the concepts of a world view and culture are depicted in chapter 1. He w...

    Isaac Newton's reputation was initially established by his 1672 paper on the refraction of light through a prism; this is now seen as a ground-breaking account and the foundation of modern optics. In it, he claimed to refute Cartesian ideas of light modification by definitively demonstrating that the refrangibility of a ray is linked to its colour, hence arguing that colour is an intrinsic property of light and does not arise from passing through a medium. Newton's later significance as a world-famous scientific genius and the apparent confirmation of his experimental results have tended to obscure the realities of his reception at the time. This paper explores the rhetorical strategies Newton deployed to convince his audience that his conclusions were certain and unchallengeable. This commentary was written to celebrate the 350th anniversary of the journal Philosophical Transactions of the Royal Society.

    Full Text Available Serendipity is a pleasant surprise of finding a particularly useful information while not looking for it. Significant historic events occurring as a result of serendipity include the discovery of the law of buoyancy (Archimedes principle by the Greek mathematician Archimedes, of the Americas by Christopher Columbus and of gravity by Sir Isaac Newton. The role of serendipity in science has been immensely beneficial to mankind. A host of important discoveries in medical science owe their origin to serendipity of which perhaps the most famous is the story of Sir Alexander Fleming and his discovery of Penicillin. In the field of dermatology, serendipity has been responsible for major developments in the therapy of psoriasis, hair disorders, aesthetic dermatology and dermatosurgery. Besides these many other therapeutic modalities in dermatology were born as a result of such happy accidents.

  5. Bohlin transformation: the hidden symmetry that connects Hooke to Newton

    International Nuclear Information System (INIS)

    Saggio, Maria Luisa

    2013-01-01

    Hooke's name is familiar to students of mechanics thanks to the law of force that bears his name. Less well-known is the influence his findings had on the founder of mechanics, Isaac Newton. In a lecture given some twenty years ago, W Arnol'd pointed out the outstanding contribution to science made by Hooke, and also noted the controversial issue of the attribution of important discoveries to Newton that were actually inspired by Hooke. It therefore seems ironic that the two most famous force laws, named after Hooke and Newton, are two geometrical aspects of the same law. This relationship, together with other illuminating aspects of Newtonian mechanics, is described in Arnol'd's book and is worth remembering in standard physics courses. In this didactical paper the duality of the two forces is expounded and an account of the more recent contributions to the subject is given. (paper)

    Biggers, John D

    2012-08-01

    IVF and embryo transfer for the treatment of human infertility has now resulted in the birth of over 4 million babies. The technique did not arise as a quantum event but was built on the efforts of many earlier workers in the fields of reproductive endocrinology and development. One should remember the famous saying of Isaac Newton: 'If I have seen further than most, it is because I have stood on the shoulder's of giants'. Ethical and moral issues have always arisen when investigators study early mammalian development, particularly human development. This paper documents these earlier studies and also draws attention to the ethical and moral arguments that inevitably arose. Copyright © 2012 Reproductive Healthcare Ltd. Published by Elsevier Ltd.

    The study of the materials and techniques employed for wall painting, complementing the information from historical and aesthetic data, contributes to the integrated knowledge of the iconographer and his period. In the 16th century, regarding the iconography in the former Byzantine area, besides the School of Crete and Francos Catelanos and his school, a third artistic personality who also created his own school, Onoufrios, appeared in central Albania and expanded his activity as a painter to northern Greece as well as nearby areas, such as Ohrid. Inscriptions documenting the works of Onoufrios are found in some of the churches that he decorated with wall paintings: “St. Apostles” (1547) Kastoria Greece, “St. Nicolas” Shelcan Albania, “St. Paraskevi” (1554), Valsh Albania, while are attributed to him the church of “St. Theodores” in Berati, Albania (before 1547) and others. He is one of the best icon painters of the whole Balkan region, and the best painter that has ever worked in Albanian territory. Onoufrios managed to combine the local painting tradition with the best tradition of the eastern (Paleologian) and western (Italian) schools, resulting in a realistic and natural depiction. He is the creator of the “Berati School” that expanded to other parts of the peninsula. His individual character can be distinguished in the work of his students: his son Nikolaos (who inherited his style in painting), Onoufrios from Cyprus, etc. Based on careful observations, we extracted number of paint samples from wall paintings of three of the above mentioned churches. Ground and paint layers were examined using micro-FTIR, Optical Microscopy, TXRF and SEM-EDS, to characterize materials and methods used by the artist to create these works. Our findings in each church are discussed and compared with the others in order to understand how and with what material and resources the painter worked and how he developed his technique. The presence of calcium carbonate as the main component in all FTIR measurements points to a fresco technique. Pigments like red and yellow ochre, carbon black, green earth, calcium carbonate are used in all cases. The use of gypsum in the plaster construction is characteristic. The deterioration of the wall paintings due to environmental effects different in every church is also examined.

    2012-01-01

    The railway suicide of Robert Enke, an internationally respected German football goal keeper, sent shockwaves throughout the world of football. We analyzed its impact on the frequency of subsequent railway suicide acts (RS). Two analytic approaches were performed applying German Railway Event database Safety (EDS) data: first, an inter-year approach comparing the incidence of RS during a predefined "index period" with identical time windows in 2006 to 2008; second, an intra-year approach comparing the number of RS 28 days before and after the incidence. To analyze a possible "compensatory deficit", the number of RS in the subsequent first quarter of 2010 was compared with the identical time windows in the preceding three years. Incidence ratios with 95% confidence intervals were estimated by Poisson regression. Findings were controlled for temperature. Compared to the preceding three years, the incidence ratio (IR) of the number of RS in the index period increased by 1.81 (1.48-2.21; p<0.001), leading to an overall percentage change of 81% (48-121%; p<0.001). Comparing the number of suicides 28 days before and after the incidence revealed an even more pronounced increase of IR (2.2; 1.6-3.0). No modifications of these associations were observed by daytime, by location of the suicide and fatality. No compensatory deficit occurred in the post-acute period. The substantial increase of RS in the aftermath of the footballer's suicide death brought about copycat behavior in an unforeseen amount, even though the media reporting was largely sensitive and preventive measures were taken.

    The content and spatial distribution of lead in the aquatic systems in two Chinese tropical cities in Hainan province (Haikou and Sanyan) show an unequal distribution of lead between the urban and the suburban areas. The lead content is significantly higher (72.3 mg/kg) in the urban area than the suburbs (15.0 mg/kg) in Haikou, but quite equal in Sanya (41.6 and 43.9 mg/kg). The frequency distribution histograms suggest that the lead in Haikou and in Sanya derives from different natural and/or anthropogenic sources. The isotopic compositions indicate that urban sediment lead in Haikou originates mainly from anthropogenic sources (automobile exhaust, atmospheric deposition, etc.) which contribute much more than the natural sources, while natural lead (basalt and sea sands) is still dominant in the suburban areas in Haikou. In Sanya, the primary source is natural (soils and sea sands).

  1. Day of mourning and time of reminiscence: Death, funeral and reminiscence of political famous persons in Serbia in socialist era and afterwards

    Directory of Open Access Journals (Sweden)

    Pavićević Aleksandra

    2009-01-01

    Full Text Available The most impressive event of death in the Yugoslav region in the last 50 years was definitely associated with death and funeral of Josip Broz Tito, in May 1980. The departure of one of the last European pharaohs has marked the beginning of an end of an era, with still hard to measure ideological and political consequences. In a symbolic sense, the departure represented a final breakdown of the proclaimed rational and secular walls of communist ideology, whose foundations contained complex religious symbolic and rhetoric. Tito came to be remembered while he was still alive. He was the only living hero portrayed in monuments, whose name was displayed in street appellations and public institutions. Media concept of his death and funeral represented a confirmation and continuation of this reminiscence; in addition, the deeper meaning of this reminiscence revealed an essential negation of the fact that the mighty ruler is actually dead. Tito's position of a supreme deity, acquired during his lifetime, was even more firmly established by his death. In this way, it could be argued that death has contributed to Broz' deification, thus extending his cult furthermore. The question remains whether the faith in his divine soul would persevere the temptations of history if he had lived for a few years more? It appears that the same question could be posed in regards to the deification of assassinated prime minister, Dr Zoran Djindjic, whose death, funeral and post mortem glory represent almost the only comparable event from the recent Serbian history, to those of the complex death related rhetoric of Broz? The post mortem image of Dr Djindjic was created based on Christian model of martyr and sufferer, but also on the model of exemplar death, that is, heroic and martyr's death in the name of nation, an important element of a special religious system, i.e., religion of nation. In 2006, during the annual commemoration dedicated to Zoran Djindjic, media coverage had turned to another event: Slobodan Milosevic had suddenly died in Scheveningen. Date of dying was not the only thing that has, for a moment, put these two celebrated politicians together. Death in prison, in Hague tribunal, while being in exile, has allowed that (short-lived post mortem glory of the former president of FRY be built according to the Christian model of martyr and sufferer. On the other hand, Milosevic's ideological position (in between communism and democracy has determined that the rhetoric associated with his departure is a combination of pagan and Christian motives. Hence, media and public images from the day he died until the funeral, were saturated with pagan symbolism and myths. It is interesting to note that these cited examples reflect the process where changes in basic secular ideologies are accompanied by a change in religious patterns as well. In turn, these religious patterns help to solve cultural contradictions and doubtfulness.

    Full Text Available Tourette′s syndrome is a clinical condition characterized by multiple motor tics and vocal tics which occurs in the age range 5-25 years and the intensity of the symptoms changes with time. It is felt that at least two remarkable personalities namely, Dr. Samuel Johnson from England, a man of letters and the compiler of the first ever English dictionary, and Wolfgang Amadeus Mozart from Austria, one of the greatest musical genius of all time, possibly suffered from this condition. Tourette′s syndrome is often described as the classical borderzone between neurology and psychiatry and every neurologist wonders at the curious and fascinating clinical features of this condition. It seems that at least two remarkable personalities, Dr. Samuel Johnson, a man of letters and the first person to compile an English dictionary, and Wolfgang Amadeus Mozart, arguably the most creative musical composer of all time, were possibly afflicted with this condition.

    Full Text Available   The possibility or impossibility of vision of God is exciting and complicated question which has allocated itself various views along Islamic thought. What become obvious from Islamic Gnostics sayings and shia imam ’s demonstration and statements is that they know the sensible vision and intellectual vision of God impossible.   They just know allowable the heartfelt vision which is the result of purity and safeness of inner faculties and therefore the verses of Quran about the vision of God or prophet ’s requesting about sighting of God have interpreted to heartfelt intuition.   This paper briefly reviews some Islamic theologies ideas with respect to their Quranic demonstrations and commentators views on this issue and comparing their understandings from Quranic verses whit each other specially verse 143 of sura Araf, in addition to speak about the meaning of intuition vision and its truth, its order, how human can be achieved that position with respect to three principles: "unity of being, velayat, love" and whit the centrality of holy Quran, hadiths and imam ’s statements. Therefore in this paper it will become obvious what is the meaning of intuition vision from Gnostics point of view and it’s the result of manifestation of God ’s attributes which man can achieve to intuition position .

    Full Text Available Bacillus anthracis es un bacilo gram positivo del grupo Bacillus cereus, que posee un genoma extremadamente monomórfco y comparte gran similitud fsiológica y de estructura genética con B. cereus y Bacillus thuringiensis. En este artículo se describen nuevos métodos moleculares para la identifcación y tipifcación de B. anthracis, basados en repeticiones en tándem de número variable o en diferencias genéticas detectadas por secuenciación, desarrollados en los últimos años. Los aspectos moleculares de los factores de virulencia tradicionales, cápsula, antígeno protector, factor letal y factor edema se describen en profundidad, junto con factores de virulencia recientemente propuestos, como los sideróforos, petrobactina y bacilibactina, la adhesina de la capa S y la lipoproteína MntA. También se detalla la organización molecular de los megaplásmidos pXO1 y pXO2, incluyendo la isla de patogenicidad de pXO1. El esqueleto genético de estos plásmidos se ha encontrado en otras especies relacionadas, probablemente debido a eventos de transferencia lateral. Finalmente, se presentan los dos receptores celulares del antígeno protector, ANTXR1/TEM8 y ANTXR2/CMG2, esenciales en la interacción del patógeno con el hospedador. Los estudios moleculares realizados en los últimos años han permitido aumentar enormemente el conocimiento de los diferentes aspectos de este microorganismo y su relación con el hospedador, pero a la vez han abierto nuevos interrogantes sobre este notorio patógeno.Bacillus anthracis, a gram-positive rod belonging to the Bacillus cereus group, has an extremely monomorphic genome, and presents high structural and physiological similarity with B. cereus and Bacillus thuringiensis. In this work, the new molecular methods for the identifcation and typing of B. anthracis developed in the last years, based on variable number tandem repeats or on genetic differences detected through sequencing, are described. The molecular aspects of traditional virulence factors: capsule, protective antigen, lethal factor and edema factor are described in depth, together with virulence factors recently proposed, such as the siderophores petrobactin and bacillibactin, the S-layer adhesin and the MntA lipoprotein. It is detailed the molecular organization of megaplasmids pXO1 and pXO2, including the pathogenicity island of pXO1. The genetic skeleton of these plasmids has been observed in related species, and this could be attributed to lateral gene transfer. Finally, the two anthrax toxin protective antigen receptors, ANTXR1/TEM8 and ANTXR2/CMG2, essential for the interaction of the pathogen with the host, are presented. The molecular studies performed in recent years have greatly increased knowledge in different aspects of this microorganism and its relationship with the host, but at the same time they have raised new questions about this noted pathogen.

    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

    Full Text Available Internet, as an educational tool and information source, has been the dream of many generations. Now it is at our fingertips, but only a very small percentage of the population uses its potential to improve their training. Governments of many countries are investing large sums of money to train new generations of these technologies. While the intention is good, goals are not always achieved. This work analyzes and discusses the evolution of the implementation of educational systems that use the Internet as an information resource in education, and the acquisition of skills that allow us to use it throughout a life-long training in the digital world.Internet como herramienta educativa y fuente de información ha sido el sueño de muchas generaciones. Ahora que está al alcance de nuestras manos, apenas un porcentaje muy reducido de la población aprovecha su potencial para mejorar su formación. Los Gobiernos de numerosos Estados están haciendo un notable esfuerzo por tratar de adiestrar a las nuevas generaciones en estas tecnologías. Si bien la intención es buena, no siempre se logran los objetivos. En este artículo se analiza y discute la evolución de la implantación de los sistemas educativos que utilizan la Red como recurso de información en la educación y la adquisición de las competencias que nos permitan aprovecharlo a lo largo de la formación necesariamente continua en el mundo digital.

    Full Text Available Cet essai considère une critique des expériences électriques de Benjamin Franklin, publiée anonymement à Londres en 1777. L'auteur s'interroge pour savoir s'il est légitime de regarder ces expériences comme « natural philosophy » dans la tradition d’Isaac Newton. Cette critique des lumières frankliniennes est considérée en connection avec les conflits de la Révolution américaine, les angoisses sociales sur la dextérité mécanique, et la hiérarchie géographique des savoirs. Les débats sur le caractère de la vraie philosophie naturelle qui touchaient les expériences de Franklin portaient également sur la constitution sociale, politique et géographique de l’autorité.This essay discusses a critical account of Benjamin Franklin’s experiments with electricity published anonymously in London in 1777. The fundamental question raised was whether Franklin’s famous experiments constituted legitimate natural philosophy in the tradition of Isaac Newton. This dim view of Franklinist enlightenment is linked to the conflicts of the American Revolution, social anxieties about mechanical ingenuity, and geographical hierarchies of knowledge-making. It is argued that debates over the legitimacy of the proper character of natural philosophy that addressed Franklinist science were also debates over the social, political and geographical constitution of authority.

    Full Text Available Paris is one of the most important capitals of the middle age. Actually, this city is universecity. Namely, Paris was remembered as a univercity, education center and art and architecture center. Paris appeared differently from the other cities. Here was an important city that East culture and West culture mixed with each other. In its environment, there were cities that have a traditional structure. It carries all the facilities of the city structure in the later middle ages. Namely, Paris is remembered firstly, while city structure is described. Like Chretien de Troyes described, Paris had the culture that made France as the first heritage of Roma and Greek. Paris is a colourful city. Perhaps, France had the most crowd population because of these facilities of Paris. Generally, undoubtedly, these facilities had a big role about the development of France civilization in the 13th century. So, in this study, we will study to introduce Paris with social-economic and culturel angles and give its appearance in the later middle ages.

  15. [Turning points in world history: urological comments on pathography of famous people: did Napoleon Bonaparte have a cystitis during the battle of Waterloo and was the battle lost because of that?].

    2011-03-01

    Apparently unimportant diseases of some prominent figures can have a considerable effect on the course of time at turning points in world history. It is quite conceivable that the Battle of Waterloo on 18 June 1815 had been lost by France because Napoleon was not in full possession of his powers, because he was suffering from acute cystitis. Adverse weather conditions with continuous rain and coldness in advance of the battle, extremely primitive hygienic conditions and more than simple quarters for the night led to the development of cystitis. Based on the records of his biographers, his personal physician and the letters to his brother, we know that Napoleon was not able to give the command to attack in the early morning as intended, but in the early noon, only because of his bad general condition. This delay of several hours led, as we all know, to the intervention of Prussia and the devastating defeat of France. Thus it appears that a relatively unimportant urological disease influenced the course of world history crucially.

  17. The history of the priority di∫pute between Newton and Leibniz mathematics in history and culture

    CERN Document Server

    Sonar, Thomas

    2018-01-01

    This book provides a thrilling history of the famous priority dispute between Gottfried Wilhelm Leibniz and Isaac Newton, presenting the episode for the first time in the context of cultural history. It introduces readers to the background of the dispute, details its escalation, and discusses the aftermath of the big divide, which extended well into recent times. One of the unique features of the book is that the mathematics behind the story is very intelligibly explained – an approach that offers general readers interested in the history of sciences and mathematics a window into the world of these two giants in their field. From the epilogue to the German edition by Eberhard Knobloch: Thomas Sonar has traced the emergence and the escalation of this conflict, which was heightened by Leibniz’s rejection of Newton’s gravitation theory, in a grandiose, excitingly written monograph. With absolute competence, he also explains the mathematical context so that non-mathematicians will also profit from the book....

  18. Retrocausation in quantum mechanics and the effects of minds on the creation of physical reality

    Science.gov (United States)

    Stapp, Henry P.

    2017-05-01

    The classical physical theories that prevailed in science from the time of Isaac Newton until the dawn of the twentieth century were empirically based on human experience and made predictions about our mental experiences, yet excluded from the dynamics all mental properties. But how can one rationally get mental things out if no mental elements are put in? The key step in the creation of quantum mechanics during 1925 by Heisenberg and his colleagues was to recognize and emphasize the essential dynamical role of mental properties in the creation of our mental empirical findings. This basic feature of quantum mechanics was cast into rigorous mathematical form by John von Neumann, and was made a central feature of contemporary relativistic quantum field theory by the work of Tomonaga and Schwinger. That theory is causally strictly forward in time. But it is explained here how it can nevertheless accommodate the seeming backward-in-time causal effects reported by D.J. Bem, and many others, by means of a slight biasing of the famous Born Rule. The purpose of this communication is to explain how those reported retrocausal findings can be explained by a strictly forward-in-time and nearly orthodox causal dynamics that, however, permits the Born Rule to be slightly biased under certain conditions. A feasible experiment is proposed that, if it gives the outcomes predicted by the proposed theory, will provide evidence in favor of this causally forward-in-time and nearly orthodox explanation of the reported retrocausal effects.

  20. The long history of iron in the Universe and in health and disease.

    Sheftel, Alex D; Mason, Anne B; Ponka, Prem

    2012-03-01

    Not long after the Big Bang, iron began to play a central role in the Universe and soon became mired in the tangle of biochemistry that is the prima essentia of life. Since life's addiction to iron transcends the oxygenation of the Earth's atmosphere, living things must be protected from the potentially dangerous mix of iron and oxygen. The human being possesses grams of this potentially toxic transition metal, which is shuttling through his oxygen-rich humor. Since long before the birth of modern medicine, the blood-vibrant red from a massive abundance of hemoglobin iron-has been a focus for health experts. We describe the current understanding of iron metabolism, highlight the many important discoveries that accreted this knowledge, and describe the perils of dysfunctional iron handling. Isaac Newton famously penned, "If I have seen further than others, it is by standing upon the shoulders of giants". We hope that this review will inspire future scientists to develop intellectual pursuits by understanding the research and ideas from many remarkable thinkers of the past. The history of iron research is a long, rich story with early beginnings, and is far from being finished.

  1. Newton and scholastic philosophy.

    Science.gov (United States)

    Levitin, Dmitri

    2016-03-01

    This article examines Isaac Newton's engagement with scholastic natural philosophy. In doing so, it makes two major historiographical interventions. First of all, the recent claim that Newton's use of the concepts of analysis and synthesis was derived from the Aristotelian regressus tradition is challenged on the basis of bibliographical, palaeographical and intellectual evidence. Consequently, a new, contextual explanation is offered for Newton's use of these concepts. Second, it will be shown that some of Newton's most famous pronouncements - from the General Scholium appended to the second edition of the Principia (1713) and from elsewhere - are simply incomprehensible without an understanding of specific scholastic terminology and its later reception, and that this impacts in quite significant ways on how we understand Newton's natural philosophy more generally. Contrary to the recent historiographical near-consensus, Newton did not hold an elaborate metaphysics, and his seemingly 'metaphysical' statements were in fact anti-scholastic polemical salvoes. The whole investigation will permit us a brief reconsideration of the relationship between the self-proclaimed 'new' natural philosophy and its scholastic predecessors.

  2. A simple model for research interest evolution patterns

    Science.gov (United States)

    Jia, Tao; Wang, Dashun; Szymanski, Boleslaw

    Sir Isaac Newton supposedly remarked that in his scientific career he was like ``...a boy playing on the sea-shore ...finding a smoother pebble or a prettier shell than ordinary''. His remarkable modesty and famous understatement motivate us to seek regularities in how scientists shift their research focus as the career develops. Indeed, despite intensive investigations on how microscopic factors, such as incentives and risks, would influence a scientist's choice of research agenda, little is known on the macroscopic patterns in the research interest change undertaken by individual scientists throughout their careers. Here we make use of over 14,000 authors' publication records in physics. By quantifying statistical characteristics in the interest evolution, we model scientific research as a random walk, which reproduces patterns in individuals' careers observed empirically. Despite myriad of factors that shape and influence individual choices of research subjects, we identified regularities in this dynamical process that are well captured by a simple statistical model. The results advance our understanding of scientists' behaviors during their careers and open up avenues for future studies in the science of science.

    ATLAS has been host to many important visitors lately. Here are a selected few: Professor Stephen Hawking visits the ATLAS cavern On Tuesday 26 September 2006 the ATLAS Collaboration was honoured by a very special visit to the detector in the underground cavern. We were pleased to guide Professor Stephen Hawking, the famous cosmologist holding the post of Lucasian Professor of Mathematics at Cambridge University (position held by Isaac Newton in the 17th century), on a tour of the ATLAS pit and the LHC tunnel. The visit was accompanied by a few colleagues from the CERN Theory group, and was only possible thanks to the professional assistance of Olga Beltramello and Bernard Lebegue, who had also taken care of all the necessary preparatory work in the cavern. Professor Hawking was very keen to check for himself the status of the detector installation, and he admired, in particular, the spectacular TGC big wheel on side C.

  4. The Abraham Pais Prize Lecture: The historical Development of the Physical Concept of Time

    Science.gov (United States)

    Jammer, Max

    2007-04-01

    The Irish physicist and mathematician John Lighton Synge once (1959) proclaimed that of all physical measurements that of time is the most fundamental and its theory ``the most basic theory of all.'' Twenty years later the Belgian physicist and chemist Ilya Prigogine declared that ``the concept of time is much more complex than we thought.'' Indeed, having studied the basic notions in physics like space, mass, force, simultaneity and written on each of them a detailed monograph, I always postponed a similar treatment of the concept of time because I realized that just by being the ``most basic'' it is also the most ``complex'' of all notions in physics and therefore a rather complicated subject of research. In fact, time, as perceived by us, is both ``flowing'' and ``enduring'' and its ``passing'' always ``lasts.'' If I venture nevertheless to offer herewith a survey of the conceptual development of the notion of time, I do so because I delimit myself to the role of time only in physics and ignore as far as possible general metaphysical, psychological or biological issues. The presentation thus ignores the history of the notion of time as conceived in the myths and religions of ancient civilizations and begins, after some brief remarks about the Pythagoreans, with the theories of time as proposed by the Pre-Socratics, Plato and Aristotle. After a critical discourse on the early proponents of an idealistic interpretation of the notion of time, like that of St. Augustine, medieval theories of time, like those which proposed the atomicity of time, are discussed. After a presentation of sixteenth century discussions of time, like that by Bruno or Gassendi, Isaac Barrow's and Isaac Newton's theories of physical time are critically analyzed. This is followed by a brief study of the conceptions of time by Locke and Berkeley and subsequently by Leibniz, who is often regarded as the first proponent of a relational or causal theory of time. Following some brief remarks about

  5. Modeling Mixed Groups of Humans and Robots with Reflexive Game Theory

    Science.gov (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.

    We characterize functions satisfying a dissipative inequality associated with a control problem. Such a characterization is provided in terms of an epicontingent solution, or a viscosity supersolution to a partial differential equation called Isaacs' equation. Links between supersolutions and epicontingent solutions to Isaacs' equation are studied. Finally, we derive (possibly discontinuous) disturbance attenuation feedback of the H ∞ problem from contingent formulation of Isaacs' equation

    Li, XiaoMing; Liao, ShiJun

    2017-12-01

    The famous three-body problem can be traced back to Isaac Newton in the 1680s. In the 300 years since this "three-body problem" was first recognized, only three families of periodic solutions had been found, until 2013 when Šuvakov and Dmitrašinović [Phys. Rev. Lett. 110, 114301 (2013)] made a breakthrough to numerically find 13 new distinct periodic orbits, which belong to 11 new families of Newtonian planar three-body problem with equal mass and zero angular momentum. In this paper, we numerically obtain 695 families of Newtonian periodic planar collisionless orbits of three-body system with equal mass and zero angular momentum in case of initial conditions with isosceles collinear configuration, including the well-known figure-eight family found by Moore in 1993, the 11 families found by Šuvakov and Dmitrašinović in 2013, and more than 600 new families that have never been reported, to the best of our knowledge. With the definition of the average period T = T/L f, where L f is the length of the so-called "free group element", these 695 families suggest that there should exist the quasi Kepler's third law T* ≈ 2:433 ± 0:075 for the considered case, where T ≈ = T | E|3/2 is the scale-invariant average period and E is its total kinetic and potential energy, respectively. The movies of these 695 periodic orbits in the real space and the corresponding close curves on the "shape sphere" can be found via the website: http://numericaltank.sjtu.edu.cn/three-body/three-body.htm.

    Eknoyan, Garabed

    2016-02-01

    Stephen Hales (1677-1761) was an English clergyman who made major contributions to a wide range of scientific topics such as botany, chemistry, pneumatics, and physiology. Early in his career he developed a keen interest in medicine through his association with his younger physician friend at Cambridge, William Stukeley (1687-1765), with whom he dissected animals and attended experiments in the laboratory of Isaac Newton. His fame as a scientist grew and by the end of his life he had achieved an international reputation as a major scientist of the Enlightenment. He is best known for his 1733 Statical Essays, in the second part of which he describes his studies in animal physiology. Most famous amongst those are his assessments of the force of the blood, which he measured in horses and dogs. Less well known and often unrecognized are his studies on the kidney in health and disease, which are the focus of this review. Amongst others Hales described the effects of hemorrhagic shock which he observed as he bled his animals while measuring their blood pressure; he then studied the effect of increasing saline perfusion pressures on the renal secretion of urine; and delved into biochemistry in exploring the composition of and solutions to dissolve bladder stones. His 1733 statement in the introduction to his hemodynamic studies that the healthy State of the Animal principally consists, in the maintaining of a due Equilibrium between the body solids and fluids literally predicts the milieu intrieur that would ultimately be formulated in 1854 by Claude Bernard (1813-1878).

    A set of humans (as every group of primates, [6]) has a behavior which is ruled by complex factors. As already remarked by Asimov ([11]) the behavior of a group of humans may change simply if some of its members know about the existence of a theory developed for describing it. Hence, the introduction of (algorithmic) procedures aimed to measure the quality of the research of scientists (e.g. bibliometric indices) could be eventually useful only if they were kept secret.

    The wide-ranging utilisation of Rapakivi Granite in St Petersburg is typified by the the famous Alexander Column, and 114 stone columns of St Isaac's Cathedralas well as the pedestal of the Nicholas I monument, and portals and basements of buildings of the Admiralty, General Staff, Senate and Synod. The stone is also frequently seen among pavement slabs and in parapets of embankments and bridges around the city. This list of examples where Rapakivi Granite has been used could be expanded further. All Rapakivi Granites used in the buildings of St.Petersburg were quarried from the so-called Vyborg massif. At present it has been found that the massif occupies an area of about 18 000 km2. In the past granite of the Vyborg massif was worked from several quarries in the vicinity of Fredrikshamn (Hamina) in Finland for use in St Peterburg. The best known granite quarries are at Piterlaks (Piuterlahti) and Gimmekyul (Hämeenkylä). Sometimes Rapakivi Granite form Finland differs in appearance from typical varieties. Thus columns of a classical portal in the house at N 7 in Pochtamtskaya Street are hewn from this greyish variety. Other examples are the plinth of the General Staff and Trade Store buildings. After the 1960s varieties from the Leningrad district, and Korosten (Ukraine) massifs were used in St Petersburg. Today it is possible to find examples of Rapakivi Granite from Finland in cities in the USA, South Africa, United Kingdom and Germany. It is a long used stone as demonstrated by its cultural heritage. It is also used as an ornamental or decorative stone in modern architecture.

  17. Making and Using Astronomical Fairy-tales on DVD in Planetarium

    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?

    VLT ISAAC Looks for Young Stars in the Famous "Pillars of Creation" Summary Through imaging at infrared wavelengths, evidence has been found for recent star formation in the so-called "Pillars of Creation" in the Eagle Nebula (also known as Messier 16 ), made famous when the NASA/ESA Hubble Space Telescope (HST) obtained spectacular visible-wavelength images of this object in 1995. Those huge pillars of gas and dust are being sculpted and illuminated by bright and powerful high-mass stars in the nearby NGC 6611 young stellar cluster . The Hubble astronomers suggested that perhaps even younger stars were forming inside. Using the ISAAC instrument on the VLT 8.2-m ANTU telescope at the ESO Paranal Observatory , European astronomers have now made a wide-field infrared image of the Messier 16 region with excellent spatial resolution, enabling them to penetrate the obscuring dust and search for light from newly born stars . Two of the three pillars are seen to have very young, relatively massive stars in their tips. Another dozen or so lower-mass stars seem to be associated with the small "evaporating gaseous globules (EGGs)" that the Hubble astronomers had discovered scattered over the surface of the pillars. These findings bring new evidence to several key questions about how stars are born . Was the formation of these new stars triggered as the intense ultraviolet radiation from the NGC 6611 stars swept over the pillars, or were they already there? Will the new stars be prematurely cut off from surrounding gas cloud, thus stunting their growth? If the new stars have disks of gas and dust around them, will they be destroyed before they have time to form planetary systems? PR Photo 37a/01 : Full wide-field ISAAC image of the Eagle Nebula.

  3. ON THE EDGE OF ARTIFICIAL LIFE AND EXISTENTIALISM: LEGITIMIZING ‘ROBO-CULTURE’ THROUGH ANARCHY, ORDER AND MANUFACTURE

    Directory of Open Access Journals (Sweden)

    2017-06-01

    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

    2015-01-01

    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.

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

    Nahin, Paul J

    2014-01-01

    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.

  6. Singularity now: using the ventricular assist device as a model for future human-robotic physiology.

    Martin, Archer K

    2016-04-01

    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.

  7. The Three Laws of Neurorobotics: A Review on What Neurorehabilitation Robots Should Do for Patients and Clinicians.

    Science.gov (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.

    Full Text Available The article views the philosophy of I. Kireyevsky in its connection with the mysti-cal and ascetic traditions of Orthodox Christianity. 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. Thus, for Kireyevsky, cognition is inseparablefrom ascetic practices

    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.

  15. Wilhelm Homberg et la chimie de la lumière

    Directory of Open Access Journals (Sweden)

    Lawrence M. Principe

    2008-03-01

    Full Text Available En 1705, Wilhem Homberg, le principal chimiste de l’Académie royale des sciences, proposa une nouvelle théorie chimique selon laquelle le Soufre principe des corps mixtes était identique à la lumière. Il affirma par la suite que cette lumière corporelle était la seule source d’activité et de changement dans les substances matérielles. Cet article montre comment la théorie de Homberg s’élabora progressivement pendant de nombreuses années sous l’influence de ses observations et des résultats de ses expériences de laboratoire, ce qui nous fournit un exemple de la manière selon laquelle un chimiste du début du XVIIIe siècle a pu développer une théorie raffinée grâce à l’interaction de la réflexion et de la manipulation. L’influence probable de la théorie de Homberg sur les fameuses « questions chimiques » de Newton est également signalée ici pour la première fois. Enfin l’article avance que nous comprendrons plus précisément l’histoire de la chimie si nous reconnaissons le caractère spécifique de la chimie et sa relative autonomie, plutôt que si nous cherchons à lui imposer des développements faciles et convenus tirés d’autres champs du savoir comme la philosophie ou la physique.In 1705, Wilhelm Homberg, the chief chemist of the Académie Royale des Sciences, proposed a new chemical theory that the Sulphur principle of mixed bodies was identical with light. He claimed further that this embodied light was the sole source of activity and change in material substances. This paper traces how Homberg’s theory emerged gradually over many years under the influence of his observations and the results of his laboratory experiments. It thus provides an example of how an early eighteenth-century chemist developed a sophisticated theory through the interplay of mind and hand. The probable influence of Homberg’s theory on Isaac Newton’s famous “chymical queries” is also noted here for the first

  16. Lots of Small Stars Born in Starburst Region

    will quickly affect their environment, but how much? At this moment, nobody knows for sure what determines the actual masses of individual stars that are formed in a very massive and turbulent gas cloud, although some ideas can now be tested with these new observations. The NGC 3603 region The new VLT observations are the key part of a larger research programme that also includes observations of the stellar cluster in the famous Tarantula Nebula in the Large Magellanic Cloud (LMC) with the NICMOS instrument on the Hubble Space Telescope (HST), as well as adaptive optics observations with ground-based telescopes of more quiescent, star-forming regions in the Galaxy. However, the team considered the starburst region NGC 3603 as the best target for this kind of investigation. It is situated in the far southern constellation Carina (The Keel) and can only be observed from the South. Moreover, such a study has to focus on the densest part of the cluster that can only be resolved with a very sensitive infrared (IR) instrument under the best seeing conditions. The VLT ANTU telescope and the multi-mode ISAAC facility are ideally suited for this purpose. NGC 3603 is located in the Carina spiral arm in the Milky Way galaxy at a distance of about 20,000 light-years (6 - 7 kpc). It is the only massive, galactic "HII-region" (so denoted by astronomers because part of its hydrogen is ionized) in which a central cluster of strongly UV-radiating stars of types "O" and "B" that ionize the nebula can be studied at visual and near-infrared wavelengths. This is because the line-of-sight is reasonably free of dust in this direction; the dimming in near-infrared radiation due to intervening matter between the nebula and us is only about a factor of 2 (contrary to 80 in visible light). The total mass of the hot O- and B-stars in NGC 3603 is over 2000 solar masses. Together, the more than fifty heavy and bright O-stars in NGC 3603 have about 100 times the ionizing power of the well

    Since the Hellenistic Period, Apelles’ most famous picture has been Aphrodite Anadyomene (Aphrodite Rising from the Sea, for which Apelles used his mistress Pancaspe of Larissa as his model for Aphrodite; another legend has it that it was inspired by the famous hetaera, the courtesan Phryne of Athens. The only work that could be said to be more famous is the unfinished painting of Aphrodite of Kos, which was left unfinished due to the artist’s death.

    In recent years, New Mexico has hosted television and motion picture film crews working on both famous and not-so-famous productions. Perhaps the most famous of these productions was the television hit Breaking Bad. Perhaps the least famous production, which almost certainly no one remembers, is the 1962-1963 television series Empire. Empire was an hour long western that chronicled the lives of 1960s ranchers in New Mexico. The series starred Richard Egan, Ryan O’Neal, Denver Pyle, and Charles Bronson. Guest stars included Robert Vaughn (The Man from Uncle), Inger Stevens (The Farmer’s Daughter), Robert Culp (I Spy), and Telly Savalas (Kojak).

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

    2005-03-01

    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

    Studies by Isaac indicate that regeneration to Douglas-fir following logging often fails because a good seed crop is destroyed in the slash fire. To prevent this loss during a good seed year, early burning before seed fall starts has been recommended. If early burning is too hazardous, only the concentrations of slash should be burned later in the fall. In contrast,...

    Although substantial progress has been made in understanding the molecular and pathological bases of neurodegeneration, there have been few successes in the clinic and a number of fundamental questions remain unanswered. Is this skepticism misplaced, or do the words of Sir Isaac Newton hold true, that "what we know is a drop, what we don't know is an ocean"?
