He was senior research investigator at the Blackett Laboratory and Emeritus Professor of Theoretical Physics at Imperial College, London. He made seminal contributions to our current understanding of symmetries and symmetry breaking in the Standard Model of particle physics. He was among those who, in 1964, proposed the mechanism of spontaneous symmetry breaking in gauge theories, together with G. Guralnik and C. Hagen in the autumn of that year, following the papers by R. Brout and F. Englert and by P. Higgs. When this new understanding was incorporated into a model proposed by S. Glashow in 1961, it led to the first formulations of the Standard Model by S. Weinberg and A. Salam. Kibble deepened our under...

  12. Walter Greiner: In Memoriam

    Science.gov (United States)

    Zen Vasconcellos, César; Coelho, Helio T.; Hess, Peter Otto

    Walter Greiner (29 October 1935 - 6 October 2016) was a German theoretical physicist. His scientific research interests include the thematic areas of atomic physics, heavy ion physics, nuclear physics, elementary particle physics (particularly quantum electrodynamics and quantum chromodynamics). He is most known in Germany for his series of books in theoretical physics, but he is also well known around the world. Greiner was born on October 29, 1935, in Neuenbau, Sonnenberg, Germany. He studied physics at the University of Frankfurt (Goethe University in Frankfurt Am Main), receiving in this institution a BSci in physics and a Master’s degree in 1960 with a thesis on plasma-reactors, and a PhD in 1961 at the University of Freiburg under Hans Marshal, with a thesis on the nuclear polarization in μ-mesic atoms. During the period of 1962 to 1964 he was assistant professor at the University of Maryland, followed by a position as research associate at the University of Freiburg, in 1964. Starting in 1965, he became a full professor at the Institute for Theoretical Physics at Goethe University until 2003. Greiner has been a visiting professor to many universities and laboratories, including Florida State University, the University of Virginia, the University of California, the University of Melbourne, Vanderbilt University, Yale University, Oak Ridge National Laboratory and Los Alamos National Laboratory. In 2003, with Wolf Singer, he was the founding Director of the Frankfurt Institute for Advanced Studies (FIAS), and gave lectures and seminars in elementary particle physics. He died on October 6, 2016 at the age of 80. Walter Greiner was an excellent teacher, researcher, friend. And he was a great supporter of the series of events known by the acronyms IWARA - International Workshop on Astronomy and Relativistic Astrophysics, STARS - Caribbean Symposium on Cosmology, Gravitation, Nuclear and Astroparticle Physics, and SMFNS - International Symposium on Strong

  2. From Jack to Double Jack Polynomials via the Supersymmetric Bridge

    Science.gov (United States)

    Lapointe, Luc; Mathieu, Pierre

    2015-07-01

    The Calogero-Sutherland model occurs in a large number of physical contexts, either directly or via its eigenfunctions, the Jack polynomials. The supersymmetric counterpart of this model, although much less ubiquitous, has an equally rich structure. In particular, its eigenfunctions, the Jack superpolynomials, appear to share the very same remarkable combinatorial and structural properties as their non-supersymmetric version. These super-functions are parametrized by superpartitions with fixed bosonic and fermionic degrees. Now, a truly amazing feature pops out when the fermionic degree is sufficiently large: the Jack superpolynomials stabilize and factorize. Their stability is with respect to their expansion in terms of an elementary basis where, in the stable sector, the expansion coefficients become independent of the fermionic degree. Their factorization is seen when the fermionic variables are stripped off in a suitable way which results in a product of two ordinary Jack polynomials (somewhat modified by plethystic transformations), dubbed the double Jack polynomials. Here, in addition to spelling out these results, which were first obtained in the context of Macdonal superpolynomials, we provide a heuristic derivation of the Jack superpolynomial case by performing simple manipulations on the supersymmetric eigen-operators, rendering them independent of the number of particles and of the fermionic degree. In addition, we work out the expression of the Hamiltonian which characterizes the double Jacks. This Hamiltonian, which defines a new integrable system, involves not only the expected Calogero-Sutherland pieces but also combinations of the generators of an underlying affine {widehat{sl}_2} algebra.

    We show that the partition functions which enumerate Donaldson-Thomas invariants of local toric Calabi-Yau threefolds without compact divisors can be expressed in terms of specializations of the Schur measure. We also discuss the relevance of the Hall-Littlewood and Jack measures in the context of BPS state counting and study the partition functions at arbitrary points of the Kaehler moduli space. This rewriting in terms of symmetric functions leads to a unitary one-matrix model representation for Donaldson-Thomas theory. We describe explicitly how this result is related to the unitary matrix model description of Chern-Simons gauge theory. This representation is used to show that the generating functions for Donaldson-Thomas invariants are related to tau-functions of the integrable Toda and Toeplitz lattice hierarchies. The matrix model also leads to an interpretation of Donaldson-Thomas theory in terms of non-intersecting paths in the lock-step model of vicious walkers. We further show that these generating functions can be interpreted as normalization constants of a corner growth/last-passage stochastic model.

    2004-01-01

    The precise alignment of the 1232 dipoles, 474 Short Straight Sections (SSS) and some other components of the LHC collider, requires the use of 6800 jacks. The specific requirements and the need for a cost-effective solution for this large production, justified the development and industrialisation of a dedicated mechanical jack. The jack was developed, and is now being produced by Centre for Advanced Technology, India, in the framework of a collaboration between CERN and the Department of Atomic Energy in India. Three jacks support each of the 32-ton heavy, 15-meter long cryo-dipole of LHC, and provide the required alignment features. Identical jacks support the lighter LHC Short Straight Sections. Presently, the mass production of 6800 jacks is in progress with two Indian manufacturers, and 3545 jacks have already been delivered to CERN by April 2004. Considering the successful performance of the jacks, it is now envisaged to extend their use, with some modifications, for even higher-demanding alignment of ...

  4. Jack Reeves and his science.

    Science.gov (United States)

    Moore, Lorna G; Grover, Robert F

    2006-04-28

    John T. (Jack) Reeves' science is reviewed across the 37 years of his research career at the University of Colorado Health Sciences Center, a period which occupied approximately half his remarkable life. His contributions centered on understanding the inter-relatedness as well as the underlying mechanisms controlling the various components of the O(2) transport system. We review here his studies on exercise performance; these encompassed about half his scientific output with the other half being devoted to the study of hypoxic pulmonary hypertension. Early studies concerned cardiac output, showing how it was a balance between O(2) uptake and O(2) extraction, and that cardiac output during exercise at high altitude was reduced, most likely because of decreased plasma volume and left ventricular filling. Jack's many studies addressed virtually every aspect of the O(2) transport system -- adding significantly to our understanding of the syndromes of altitude illness, the mechanisms by which ventilatory sensitivity to hypoxia and hypercapnia influenced ventilatory acclimatization, and the contributions of the various limbs of the autonomic nervous system on systemic blood pressure, vascular resistance and substrate utilization. His scientific career ended abruptly in 2004 when struck by a car while biking to work, but his legacy remains in his more than 385+ research articles or chapters, the 40+ fellows he trained, and the countless number of younger (and older) scientists for whom he served as a role model for learning how to scrutinize their data and present their findings in clear and sometimes bold prose. An integral man, he is sorely missed.

  5. Jack superpolynomials: physical and combinatorial definitions

    International Nuclear Information System (INIS)

    Desrosiers, P.; Mathieu, P.; Lapointe, L.

    2004-01-01

    Jack superpolynomials are eigenfunctions of the supersymmetric extension of the quantum trigonometric Calogero-Moser-Sutherland Hamiltonian. They are orthogonal with respect to the scalar product, dubbed physical, that is naturally induced by this quantum-mechanical problem. But Jack superpolynomials can also be defined more combinatorially, starting from the multiplicative bases of symmetric superpolynomials, enforcing orthogonality with respect to a one-parameter deformation of the combinatorial scalar product. Both constructions turn out to be equivalent. (author)

    Embarking on a major expansion plan, the company is constructing a new additional overland conveyor coal to a recently refurbished prep plant. Jim Walter Resources recently invested $20 million in a new 5-mile overland conveyor system to haul coal from the No.7 deep coal mine in Alabama to the No.5 coal preparation plant. The size of the No.7 mine was effectively doubled. The article describes how this expansion move was decided upon and describes the design and installation of the new conveyor which spans approximately 5 miles. 4 photos.

  8. Walter Pater and the Language of Sculpture

    are closely linked. Going beyond Pater's views on sculpture as an art form, this study traces the notion of relief (rilievo) and hybrid form in Pater, and his view of the writer as sculptor, a carver in language. Alongside her treatment of rilievo as a pervasive trope, Lene Østermark-Johansen also employs...... the idea of rivalry (paragone) more broadly, examining Pater's concern with positioning himself as an art critic in the late Victorian art world. Situating Pater within centuries of European aesthetic theories as never before done, Walter Pater and the Language of Sculpture throws new light...

    2016-01-01

    WALTER R. COURTENAY, JR., ichthyologist and retired professor, Florida Atlantic University, Boca Raton, Florida, died in Gainesville, Florida, on 30 January 2014 at age 80. Walt was born in Neenah, Wisconsin, on 6 November 1933, son of Walter and Emily Courtenay. Walt's interest in fish began at a young age as evidenced by a childhood diary in which at 13 years of age he wrote about his first catch—a two-and-a-half pound “pike” from Lake Winnebago. When Walt turned ten, the family moved from Wisconsin to Nashville, Tennessee, the move precipitated by his father accepting a position as pastor of the First Presbyterian Church. During those early days in Nashville, Walt's father would take summers off and travel to Michigan to teach at Camp Miniwanca along the shore of Lake Michigan where father and son honed their angling skills. It was also at that time Walt's father had definite views on what his son should be doing in adult life—in Walt's case it was to become a medical doctor. However, his Woods Hole internship in marine biology and oceanography toward the end of his undergraduate years was a transformative experience for him so much so that he abandoned all ideas of becoming a medical doctor and instead specialized in ichthyology and oceanography. Apart from the inherent interest and opportunities Woods Hole opened to him, being back at the shore of a large body of water, in this case the Atlantic Ocean, was far more interesting than sitting in lectures on organic chemistry. With that, Walt completed his B.A. degree at Vanderbilt University in 1956. In 1960 while in graduate school in Miami, Walt met and married Francine Saporito, and over the next several years had two children, Walter III and Catherine. He went on to receive his M.S. in 1961 from The Rosenstiel School of Marine and Atmospheric Science at the University of Miami on the systematics of the genus Haemulon (grunts) and his Ph.D. degree in 1965 working under his advisor C.

    Full Text Available What if Walter Benjamin actually made it to New York as he was escaping the Nazis, settling there for the rest of his long life? What if he was working on a sequel to his Arcades Project, translating his ideas about Paris, capital of the nineteenth century, to his new city and own epoch? And what if I inadvertently discovered the manuscript of this so-called Manhattan Project, and decided to write a study dedicated to the unearthed text? This paper offers a few reflections on, and quotations from, the book that I am currently, truly working on, which is an analysis of a phantom of a book, inspired by a real collection of reflections and quotations that were made in preparation for another book that was also never written.

  16. Walter Benjamin's allegory and the modernity

    Directory of Open Access Journals (Sweden)

    João Batista Pereira

    2013-12-01

    Full Text Available Committed since Classical Antiquity with the rhetoric and the rules of oratory, the allegory was like a displaced metaphor, striving for clarity of speech. That purpose was transfigured throughout the Middle Ages, when its use was linked to decency and morality, a convention which was changed in Romanticism, when it met its demise. From the texts proposed by Walter Benjamin, its existence was perceived as a resource illuminating the aesthetic universe in the social times, a figure of speech tied to the historical context. We adopt in this article a dialectical perspective as a methodological that more accurately illustrates the contours assumed by allegory in modernity. With the light of experiences in a changing world of insecurity in its own values, it is now envisioned as a category indicting of fragmented representation of society, allowing us to understand the limits of literature as a vehicle in critical of reality.

  17. Obituary: Walter Alexander Feibelman, 1930-2004

    Science.gov (United States)

    Oergerle, William

    2005-12-01

    Walter Alexander Feibelman, 79, an astronomer who discovered the E-ring of Saturn, died of a heart attack 19 November 2004 at his home at Riderwood Village in Silver Spring, Maryland. Walter was born 30 October 1925 in Berlin, Germany to Bernard and Dora Feibelman. He came to the United States with his parents in 1941. They were some of the last German Jews to flee Nazi Germany. Years later, he reported his experiences in an account contributed to the U.S. Holocaust Memorial Museum. As a youth, he worked at a cleaning shop and as a soda jerk before taking a course in tool and die making. He worked at the Abbey Photo Corp. in New York and in a model-making firm, where he constructed models of aircraft for use in identification courses by the Army Air Forces. After high school, he attended the Carnegie Institute of Technology and received his BS degree in 1956. Until 1969, he was a research scientist at the University of Pittsburgh. While working as an assistant research professor in physics and astronomy at the University of Pittsburgh in 1967, he examined a photo of Saturn taken a year earlier at the university's Allegheny Observatory. The E-ring -- unlike the bright main rings, A, B, C, D and F -- is faint and not easily spotted. He paired his observation with calculations and announced his discovery, which remained unconfirmed until the Pioneer 11 flyby in 1979. Walter joined the Optical Astronomy Division of Goddard Space Flight Center in Greenbelt in 1969, and worked there until 2002, when he became an emeritus astronomer at NASA. He became associated with the International Ultraviolet Explorer project, and worked on developing detectors for the orbiting observatory's spectrograph. The project turned out to be one of NASA's most successful observatories, operating from 1978 to 1996. In his scientific career, he published more than 200 refereed articles, mainly on hot stars and planetary nebulae. He also wrote papers in the fields of photography, spectroscopy

    A three-dimensional density-functional molecular-dynamics code is developed for the Thomas-Fermi density functional as a prototype for density functionals using only the density. Following Car and Parrinello [Phys. Rev. Lett. 55, 2471 (1985)], the electronic density is treated as a dynamical variable. The electronic densities are verified against a multi-ion Thomas-Fermi algorithm due to Parker [Phys. Rev. A 38, 2205 (1988)]. As an initial application, the effect of electronic polarization in enhancing ionic diffusion in strongly coupled plasmas is demonstrated

    Alfred Walter Campbell (1868-1937) established the basic cytoarchitectonic structure of the human brain while he was working as a pathologist at the Rainhill Lunatic Asylum near Liverpool in the United Kingdom. He returned to Australia in 1905 and continued doing research while establishing a neurological practice. His research over the next 17 years focused on four topics: (a) localisation in the cerebellum, (b) the neuroses and psychoses in war, (c) localisation in the cerebral cortex of the gorilla, and (d) the causes and pathology of the mysterious Australian "X" Disease (later known as Murray Valley encephalitis). In this article, I elaborate on his research in these areas, which provided evidence (a) against Louis Bolk's thesis that variation in the size of the cerebellar cortex reflected variation in the amount of cortex controlling various groups of muscle, (b) against the view that the neuroses and psychoses in war were different from those in civilian life, (c) for a parcelation of the cortex of the gorilla brain that supported his earlier findings in the higher apes, and (d) on the cause and pathophysiology of Australian "X" disease. Much of this research was overlooked, but it remains of considerable value and historical significance.

    2018-03-01

    We consider a particle dressed with boundary gravitons in three-dimensional Minkowski space. The existence of BMS transformations implies that the particle’s wavefunction picks up a Berry phase when subjected to changes of reference frames that trace a closed path in the asymptotic symmetry group. We evaluate this phase and show that, for BMS superrotations, it provides a gravitational generalization of Thomas precession. In principle, such phases are observable signatures of asymptotic symmetries.

    2009-01-01

    Walter G. Egan, a scientist and engineer with a professional life spanning well over half a century, died on 3 November 2003. Born to Caroline and George Egan on 12 October 1923 in New York City, Egan studied Electrical Engineering at the City College of New York from 1941 until 1943 when he was called to active duty in World War II, switching from enlisted reserve status. During the war, he served honorably in both the Signal Corps and the Medical Corps. Following his discharge in 1946, he resumed his college studies, obtaining a BEE in 1949 from City College of New York, an MA in Physics in 1951 from Columbia University, and a PhD in Solid State Physics in 1960 from the Polytechnic Institute of Brooklyn. Egan's PhD thesis was "Ferromagnetic Resonance in thin Nickel Films," performed under advisor H. Juretschke. Egan's professional career covered both industry and academia. In the summer of 1942, he worked for the Bruce Engineering Company. From 1957 to 1963, he worked for Ford Instrument Company, a Division of Sperry Rand Corporation, successively as an Engineering Project Supervisor, Assistant Director of Research, and Executive Assistant to the Director of Research. From 1964 to 1986 Egan worked as a Staff Scientist at the Grumman Corporation Corporate Research Center where his pioneering work consisted of research and development of remote sensing equipment and techniques for the remote sensing of terrestrial and space targets and backgrounds. I came to know and work with him during his tenure at the Grumman Corporation, where we co-authored many papers and a book. His insight into remote sensing engineering and research, shared willingly with younger colleagues, was a major stimulus to my future research in this field. Egan instilled a sense of discipline in publication, so our work could be shared with others in a timely way. This drive to share his knowledge with others also made him an excellent teacher. Subsequently, he held the position of Research

    An Act of Parliament in 1540 uniting the barbers and surgeons to form the Barber-Surgeons' Company represented an important foundation stone towards better surgery in England. Thomas Vicary, who played a pivotal role in promoting this union, was a leading surgeon in London in the middle of the 16th century. While Vicary made no direct contribution to surgical knowledge, he should be remembered primarily as one who contributed much towards the early organization and teaching of surgery and to the consequent benefits that flowed from this improvement.

    Nonextensive Thomas-Fermi model was father investigated in the following directions: Heavy atom in strong magnetic field. following Shivamoggi work on the extension of Kadomtsev equation we applied nonextensive formalism to father generalize TF model for the very strong magnetic fields (of order 10e12 G). The generalized TF equation and the binding energy of atom were calculated which contain a new nonextensive term dominating the classical one. The binding energy of a heavy atom was also evaluated. Thomas-Fermi equations in N dimensions which is technically the same as in Shivamoggi (1998) ,but behavior is different and in interesting 2 D case nonextesivity prevents from becoming linear ODE as in classical case. Effect of nonextensivity on dielectrical screening reveals itself in the reduction of the envelope radius. It was shown that nonextesivity in each case is responsible for new term dominating classical thermal correction term by order of magnitude, which is vanishing in a limit q->1. Therefore it appears that nonextensive term is ubiquitous for a wide range of systems and father work is needed to understand the origin of it.

  6. In conversation with Nobel Laureate Jack Steinberger

    CERN Multimedia

    2011-01-01

    Awarded the 1988 Nobel Prize for Physics for his discovery of the muon neutrino, Jack Steinberger has been part of the CERN establishment for almost 50 years. He recently celebrated his 90th birthday and can still be found in his CERN office on an almost daily basis. If you happened to have a coffee with him… this is what he would tell you: his recollections, and thoughts about the present and future of particle physics.   I’ve been at CERN for 45 years, and I’ve seen this organisation go through a lot. Experiments have grown significantly and so have the aspirations of particle physics.

  12. Thomas Fermi model of finite nuclei

    International Nuclear Information System (INIS)

    Boguta, J.; Rafelski, J.

    1977-01-01

    A relativistic Thomas-Fermi model of finite-nuclei is considered. The effective nuclear interaction is mediated by exchanges of isoscalar scalar and vector mesons. The authors include also a self-interaction of the scalar meson field and the Coulomb repulsion of the protons. The parameters of the model are constrained by the average nuclear properties. The Thomas-Fermi equations are solved numerically for finite, stable nuclei. The particular case of 208 82 Pb is considered in more detail. (Auth.)

  13. Walter Lippmann’s Ethical Challenge to the Individual

    2012-01-01

    Full Text Available This essay analyzes in hermeneutic fashion random concepts of the individual from three of philosopher Walter Lippmann’s major works, Liberty and the News, Public Opinion, and The Phantom Public. The article addresses the following: By considering Lippmann’s multileveled representation of the individual, 21st-century media professionals can become empowered to avoid emotivism and strive toward a more narrative-based form of ethics. The article compares and contrasts Lippmann’s representation of the individual with John Dewey’s Great Community and Daniel Boorstin’s notion of the pseudo-event.

    Full Text Available Condemned to a dubious media representation in early cinema through the novels of the late nineteenth century, the North American Indians never had a high profile in films of this period. However, an animator, Walter Lantz, has a high degree of characterization of Native Americans in his work. The aim of this paper is to study the role of Native Americans in these cartoons and analyze the social implications of these choices, using the concepts of apparatus and formula. Furthermore, the analysis will include a portrayal of the American media scene before and after Lantz, seeking disruptions and legacies.

  2. JACK - ANTHROPOMETRIC MODELING SYSTEM FOR SILICON GRAPHICS WORKSTATIONS

    Science.gov (United States)

    Smith, B.

    1994-01-01

    JACK is an interactive graphics program developed at the University of Pennsylvania that displays and manipulates articulated geometric figures. JACK is typically used to observe how a human mannequin interacts with its environment and what effects body types will have upon the performance of a task in a simulated environment. Any environment can be created, and any number of mannequins can be placed anywhere in that environment. JACK includes facilities to construct limited geometric objects, position figures, perform a variety of analyses on the figures, describe the motion of the figures and specify lighting and surface property information for rendering high quality images. JACK is supplied with a variety of body types pre-defined and known to the system. There are both male and female bodies, ranging from the 5th to the 95th percentile, based on NASA Standard 3000. Each mannequin is fully articulated and reflects the joint limitations of a normal human. JACK is an editor for manipulating previously defined objects known as "Peabody" objects. Used to describe the figures as well as the internal data structure for representing them, Peabody is a language with a powerful and flexible mechanism for representing connectivity between objects, both the joints between individual segments within a figure and arbitrary connections between different figures. Peabody objects are generally comprised of several individual figures, each one a collection of segments. Each segment has a geometry represented by PSURF files that consist of polygons or curved surface patches. Although JACK does not have the capability to create new objects, objects may be created by other geometric modeling programs and then translated into the PSURF format. Environment files are a collection of figures and attributes that may be dynamically moved under the control of an animation file. The animation facilities allow the user to create a sequence of commands that duplicate the movements of a

  4. Walter Charleton (1620 - 1707 e sua Teoria Atômica The atomic theory of walter charleton (1620 - 1707

    Directory of Open Access Journals (Sweden)

    Paulo Alves Porto

    1997-06-01

    Full Text Available Several authors in the 17th century used the atomic hypothesis to explain observable phenomena. This paper analyzes some ideas about chemical transformation proposed by the English physician Walter Charleton. In Physiologia Epicuro-Gassendo-Charltoniana (London, 1654, Charleton examined philosophical aspects of the atomic theory, and suggested that the best explanation for all natural phenomena would be only in terms of atoms and their motions. Sometimes, however, he had to attribute to the atoms some kind of "internal virtue", to explain more complex properties of the matter. His idea of "element", and the little use of experimentation and quantification, also limited the range of Charleton's theory.

  6. Pipe failure probability - the Thomas paper revisited

    International Nuclear Information System (INIS)

    Lydell, B.O.Y.

    2000-01-01

    Almost twenty years ago, in Volume 2 of Reliability Engineering (the predecessor of Reliability Engineering and System Safety), a paper by H. M. Thomas of Rolls Royce and Associates Ltd. presented a generalized approach to the estimation of piping and vessel failure probability. The 'Thomas-approach' used insights from actual failure statistics to calculate the probability of leakage and conditional probability of rupture given leakage. It was intended for practitioners without access to data on the service experience with piping and piping system components. This article revisits the Thomas paper by drawing on insights from development of a new database on piping failures in commercial nuclear power plants worldwide (SKI-PIPE). Partially sponsored by the Swedish Nuclear Power Inspectorate (SKI), the R and D leading up to this note was performed during 1994-1999. Motivated by data requirements of reliability analysis and probabilistic safety assessment (PSA), the new database supports statistical analysis of piping failure data. Against the background of this database development program, the article reviews the applicability of the 'Thomas approach' in applied risk and reliability analysis. It addresses the question whether a new and expanded database on the service experience with piping systems would alter the original piping reliability correlation as suggested by H. M. Thomas

  15. Walter Benjamin e Paris: individualidade e trabalho intelectual

    Directory of Open Access Journals (Sweden)

    Renato Ortiz

    2000-05-01

    Full Text Available Este artigo é uma leitura do texto de Walter Benjamin Paris capital do século XIX. A partir do conjunto de anotações que Benjamin faz de diversos livros consultados, principalmente durante sua pesquisa na Bibliothèque Nationale, o autor pretende trabalhar a noção de indivíduo vinculando-a a dois temas. Primeiro, a emergência do flâneur como tradução do espírito de mobilidade que se inaugura com a modernidade. Para isso a discussão sobre a noção de espaço, particularmente no que diz respeito a cidade de Paris, é importante. O flâneur surge assim como um indivíduo desenraizado que se locomove através do espaço urbano remodelado. Segundo, uma aproximação entre o ato da flânerie e o trabalho intelectual. Considerando a flânerie como uma atividade intelectual o autor mostra como os temas do distanciamento e da construção do objeto são relevantes tanto para o flâneur-detetive quanto para a reflexão nas ciências sociais.This paper is an interpretation of Walter Benjamins Paris, Capital of the 19th Century. Based on the notes Benjamin made on several books he read, mainly during his research at the Bibliotèque Nationale, the author discusses the notion of the individual linking it to two themes. First, to the emergence of the flâneur as a translation of the spirit of mobility which starts with modernity. The discussion on the notion of space, especially where it concerns Paris, is essential for this analysis. The flâneur is seen as an uprooted individual who moves around the remodelled urban space. Second, to the proximity between the act of flânerie and that of intellectual work. Taking flânerie to be intellectual activity, the author shows how the themes of the distancing and the construction of the object are relevant, both to the detective-flâneur and to the reflection in social sciences.

  16. Cholera in Thomas Mann's Death in Venice.

    Science.gov (United States)

    Rütten, Thomas

    2009-01-01

    The article sets the cholera motif in Thomas Mann's famous novella Death in Venice against the historical context from which it partially originates. It is shown that this motif, while undoubtedly appropriated to serve Mann's own poetic ends, has a solid grounding in historical and autobiographical fact, thus blurring the boundaries between fact and fiction. The article illustrates the verifiable events of the outbreak of the Venetian cholera epidemic in May 1911, which Mann partly witnessed himself, during a holiday trip to Brioni and Venice, and partly heard and read about. It is established that Thomas Mann's account of the cholera in Venice in his novella is characterised by a rare and almost preternatural insightfulness into an otherwise murky affair that was marked by rumours, speculations and denials.

    In addition to his work on physical optics, Thomas Young (1773-1829) made several contributions to geometrical optics, most of which received little recognition in his time or since. We describe and assess some of these contributions: Young's construction (the basis for much of his geometric work), paraxial refraction equations, oblique astigmatism and field curvature, and gradient-index optics. © 2011 The Authors.

    The SpyJack Remote Monitoring System, a stand-alone, single-site remote well monitoring system that works off its own embedded controller is described. The supervisory control and data acquisition (SCADA) unit, developed by CORE Technologies Inc., has an integrated voice/alarm system, monitoring sensors installed at remote well sites continuously 24 hours a day with a digital camera, with 300 degrees of visual confirmation capability. It can also be used as a surveillance tool against terrorism as has been shown in the case of some recent debilitating attacks on remote wells in Alberta. SpyJack monitors flow rates and pressures, pumpjack stroke rates, sucker rod temperature, load cell and engine shut-off relay, as well as ambient temperature, tank levels, and motion detection. At the office, SpyJack Well Management Interface uses nine drop-down screens to take users through the remote monitoring and control of each site. The screens include production sensors, line sensors, dyno chart, environmental/safety sensors and sensor information and set up. Currently under development is the unsolicited dial-out capability. When implemented the system will send out information at pre-determined times, such as every four hours, or at specific times during the day. Compressing images to enable speedier downloading is also being planned

    Full Text Available Cosa ne è del desiderio all’interno del Kitsch, sistema in cui la vita è vissuta come uno spot pubblicitario e l’identità come una eterna performance? In una dimensione utopistica in cui l’uomo non cerca altro che una continua soddisfazione come possono trovare spazio le tensioni e le mancanze che muovono il desiderio? Dopo una premessa teorica su cosa è il Kitsch, l’intervento si propone di rispondere al quesito attraverso tre opere di Walter Siti: i romanzi Troppi paradisi e Autopsia dell’ossessione e il reportage narrativo Il canto del diavolo. In queste opere vengono individuati tre paradigmi dell’esperienza Kitsch: il turismo, la televisione e un certo tipo di prostituzione. Indagandone le modalità e analizzando le riflessioni dell’autore in merito si vedrà come si deforma il desiderio quando si trova a dover fare i conti con il perpetuo sforzo del Kitschmensch di camuffarsi, per dirla con Kundera, «dans le miroir du mensonge embellissant et de s’y reconnaître avec une satisfaction émue». La meravigliosa e sostenibilissima leggerezza dell’essere che assurge a cifra interpretativa dell’utopia Kitsch non prevede la presenza del desiderio se non nella sua veste di “realizzabilità”: il desiderio Kitsch, il surrogato del desiderio, è offerto in omaggio col prodotto che lo appaga.

  4. Gerard Manley Hopkins and Walter Pater : the labyrinths of transience

    Directory of Open Access Journals (Sweden)

    Mirko Starčević

    2016-12-01

    Full Text Available Transience forming life's very essence left an indelible mark on the creative explorations of Gerard Manley Hopkins and Walter Pater. The permanently indeterminable presence of mutability made both of them face the umbrous and unknowable aspect of death, thus revealing unto them the task of determining the role of art in life ruled by ceaseless corrosion. Pater accepts the flux of mutability as the primary particle in the revelatory act of the authentic creative experience. The power of that which is frolicsome in art augments the constitution of life's essence submerged in the unsettled condition of fate. Hopkins the priest particularly in his theoretic excursions recognizes in art itself only an approximate value to the timeless grandeur of God's ubiquity. His poetry, however, presents a dissimilar narrative. The poetic image that Hopkins forges corresponds to the mode of exposed individuality of the Romantic spirit, which Pater perceives as the harmony of strangeness and beauty. During Hopkins' student days at Oxford, Pater's relationship to the young poet was not confined to coaching only. Much of their time they spent in conversation, meditating upon the essential principles of artistic expression. Pater influenced Hopkins greatly and contributed impressively to the discipline of his poetic heart. Traces of this companionship do not find the path to Hopkins' religious ruminations; they announce their own existence, although very subtly, upon the individual levels of Hopkins' poetic yearnings.

    Full Text Available This article describes the typical algorithms for choosing modern tools made by foreign firms Sandvik Coromant and Walter. The use of modern tools is effective on both new and old equipment. Algorithms ensure orderly operation of engineers in the development of new or upgrading old processes, and may also be useful for students enrolled in the specialty "Mechanical Engineering". The use of modern tools is effective on both new and old equipment. Correctly chosen tool make it possible for you to quickly recoup the cost of new equipment and significantly improve the work of the old equipment. Currently, all cutting tools can be divided into the following groups: a a solid; b composite; c assembly; d modular (dial-up. In composite cutting tools and parts theholders are attached permanently. For example, the attachment can be blocked by welding or soldering. At modular and modular cutting tools and parts are detachable. In those parts of the modular tool there are separate assembly units (modules with standardized mounting surface. Thus one and the same cutter head may be attached to a holder (mandrel housings of different configuration and function. The choice of the cutting part of such tools includes determining the shape and size of the indexable insert (SMP, the geometry of its front surface, corner radius and tool material. Selecting the holder (mandrel body includes determining its type and size. It is necessary to take into account the possibility of technological equipment (type and size of the mounting surfaces of the tool holder and tool spindle.After selecting the tool it is necessary to determine working regimes

  6. Taking Charge: Walter Sydney Adams and the Mount Wilson Observatory

    Brashear, R.

    2004-12-01

    The growing preeminence of American observational astronomy in the first half of the 20th century is a well-known story and much credit is given to George Ellery Hale and his skill as an observatory-building entrepreneur. But a key figure who has yet to be discussed in great detail is Walter Sydney Adams (1876-1956), Hale's Assistant Director at Mount Wilson Observatory. Due to Hale's illnesses, Adams was Acting Director for much of Hale's tenure, and he became the second Director of Mount Wilson from 1923 to 1946. Behind his New England reserve Adams was instrumental in the growth of Mount Wilson and thus American astronomy in general. Adams was hand-picked by Hale to take charge of stellar spectroscopy work at Yerkes and Mount Wilson and the younger astronomer showed tremendous loyalty to Hale and Hale's vision throughout his career. As Adams assumed the leadership role at Mount Wilson he concentrated on making the observatory a place where researchers worked with great freedom but maintain a high level of cooperation. This paper will concentrate on Adams's early years and look at his growing relationship with Hale and how he came to be the central figure in the early history of Mount Wilson as both a solar and stellar observatory. His education, his years at Dartmouth and Yerkes (including his unfortunate encounter with epsilon Leonis), and his formative years on Mount Wilson are all important in learning how he shaped the direction of Mount Wilson and the development of American astronomy in the first half of the 20th century. This latter history cannot be complete until we bring Adams into better focus.

    2009-02-01

    Thomas Szasz's original critique of the concept of 'mental illness' is almost 50 years old. Over that half century Szasz has maintained a consistent campaign against the 'Therapeutic State', challenging the paternalism of coercive psychiatry and defending liberty and autonomy. Despite his widespread celebrity Szasz continues to be misread and misrepresented. In this paper we review some of Szasz's key ideas, in the light of Clarke's recent critique, setting this within the context of 'mental health nursing' and the problems in living affecting persons worldwide.

    2017-12-01

    Data on the distribution of reduced partial neutron widths and on the distribution of total gamma decay widths disagree with the Porter-Thomas distribution (PTD) for reduced partial widths or with predictions of the statistical model. We recall why the disagreement is important: The PTD is a direct consequence of the orthogonal invariance of the Gaussian Orthogonal Ensemble (GOE) of random matrices. The disagreement is reviewed. Two possible causes for violation of orthogonal invariance of the GOE are discussed, and their consequences explored. The disagreement of the distribution of total gamma decay widths with theoretical predictions cannot be blamed on the statistical model.

    The aim of this study was to analyze the relationships between the head-out aquatic exercise "Jumping jacks" kinematics and the musical cadence in healthy and fit subjects. Five young women, with at least one year of experience conducting head- out aquatic programs were videotaped in the frontal plane, with a pair of cameras providing a double projection (above and below the water surface). Subjects performed an incremental protocol of five bouts (120 b·min(-1), 135 b·min(-1), 150 b·min(-1), 165 b·min(-1) and 180 b·min(-1)) with 16 full cycles of the "Jumping jacks" exercise. Data processing and calculation of upper limbs' (i.e. hands), lower limbs' (i.e. feet) and center of mass' 2D linear velocity and displacement were computed with the software Ariel Performance Analysis System and applying the 2D-DLT algorithm. Subjects decreased the cycle period during the incremental protocol. Significant and negative relationships with the musical cadence were verified for the center of mass and upper limbs vertical displacement. On the other hand, for the lower limbs lateral velocity, a significant and positive relationship was observed. It is concluded that expert and fit subjects increase the lower limb's velocity to maintain the range of motion, while the upper limb's displacement is reduced to coupe the music cadence. Key pointsWhile performing the Jumping Jacks, expert and fit subjects increase their lower limbs segmental velocity to maintain the range of motion.The upper limbs displacement is reduced to maintain the music cadence.Expert and fit subjects present similar response for alternating or simultaneously head-out aquatic exercises when increasing the music cadence.

    The Bo (meaning 'ox' in the Venetian dialect) is the historic seat of the University of Padua, founded in 1222. A full-length portrait of Thomas Linacre stands in its prestigious Sala dei Quaranta (Hall of the Forty), so called because of the portraits of forty great foreign scholars of the University, painted by Giacomo dal Forno in 1942. Thomas Linacre came to Italy in 1485, following an embassy by Henry VII to the Vatican. Linacre visited Bologna, Florence, Rome, Venice, Vicenza and Padua, where he took his degree in medicine in 1496 with great distinction. During his stay in Italy he met illustrious humanists and physicians, including Poliziano, Hermolaus Barbarus and Aldus Manutius Romanus, and Nicolaus Leonicenus who further stimulated him to the translation of classic works by Hippocrates and Galen. In 1518 Linacre played a pivotal role in the foundation of the Royal College of Physicians in London which, as first President, he organized on the basis of Italian models. With his portrait, the University of Padua celebrates the life and work of an astonishing figure linking the Italian and English medical cultures.

    In this first scientific biography of Walter Schottky at the one hand the origin of his scientific and technical works is reproduced and put in the physical-historical connection of his time. At the other hand his special role in the research strategy of the Siemens company becomes clear, which could in the framework of this research project for the first time be identified. Also psychological aspects were essentially included in the study, because else the binding of the particular more corresponding to an ivory-tower than and industrial physicist personality of Schottky to the Siemens trust not would be understandable. The example of Walter Schottky shows the importance of the researching individuum, which until today undoubtly can be an important element of company-internal innovation processes not only contrarily but also in the transition to scientific team work.

    Chapman, H D

    2012-01-01

    Thomas K. Jeffers has made many significant contributions to our understanding of the biology of the parasite Eimeria, the cause of coccidiosis in poultry. His work has had direct practical application for the control of this widespread disease. Topics discussed include Jeffers' pioneering work concerned with genetics of the host response to infection, the nature of biological and immunological intraspecific variation, drug resistance and discovery, field surveys of resistance, and his most recognized achievement-the demonstration that the lifecycle of coccidia may be altered by artificial selection. Parasites so modified are attenuated but retain their immunogenicity, a discovery that has led to the development of live vaccines that are inherently non-pathogenic. This article provides a brief biography and describes the contributions that Jeffers has made to our knowledge of coccidiosis.

  18. [Thomas Schwencke and Wolfgang Amadeus Mozart].

    Hillen, Harry F P

    2010-01-01

    Thomas Schwencke (1694-1767) was Professor of Anatomy and Surgery and Lecturer in Obstetrics at the Surgical School in The Hague, the Netherlands. In 1743 he published the very first textbook on haematology. Furthermore, he described his observations on the variolation of smallpox, and published the design of a new obstetric instrument. Schwencke was physician of the city of The Hague and also physician at the court of the princes van Nassau-Weilburg. In 1765 Princess Caroline of Nassau-Weilburg invited the young Wolfgang Amadeus Mozart to perform concerts. During his Dutch tour the young Mozart fell seriously ill, probably from typhoid fever. At the request of the court Mozart was seen for a second opinion and thereafter successfully treated by Schwencke. Mozart could continue his concert tour and Schwencke's reputation as Mozart's physician was established.

  19. Thomas precession: correct and incorrect solutions

    Malykin, Grigorii B

    2006-01-01

    A wealth of different expressions for the frequency of the Thomas precession (TP) can be found in the literature, with the consequence that this issue has been discussed over a long period of time. It is shown that the correct result was obtained in the works of several authors, which were published more than forty years ago but remained unnoticed against the background of numerous erroneous works. Several TP-related physical paradoxes formulated primarily to disprove the special relativity theory are shown to be fallacious. Different techniques for deriving the correct expression are considered and the reasons for the emergence of the main incorrect expressions for the TP frequency are analyzed.

    Full Text Available In the book “God - A Biography,” Jack Miles aims to introduce ourselves Creator-God as a literary character. Miles developed a narrative based on concept aristotelian, in other words, the structure of the work is made from beginning to end. This procedure established a harmony arising from the interaction between the parties, which contributes to scrutinize the precise details of the story of the main protagonist. We decided to highlight that time some characteristics of the main character of the work and compare them to the character Hamlet, by William Shakespeare, because from the beginning of the narrative to completion Miles calls the reader’s attention to the play Shakespeare.

    2009-09-01

    The plant design management system (PDMS) is an integrated application which includes a database and is useful when designing complex 3-D industrial projects. It could be used to simplify the most difficult part of a subsea oil extraction project—detailed pipeline design. It could also be used to integrate the design of equipment, structures, HVAC, E-ways as well as the detailed designs of other specialists. This article mainly examines the applicability of the Vantage PDMS database to pipeline projects involving jack-up drilling ships. It discusses the catalogue (CATA) of the pipeline, the spec-world (SPWL) of the pipeline, the bolt tables (BLTA) and so on. This article explains the main methods for CATA construction as well as problem in the process of construction. In this article, the authors point out matters needing attention when using the Vantage PDMS database in the design process and discuss partial solutions to these questions.

  1. Thomas Piketty’s capitalism revisited

    Directory of Open Access Journals (Sweden)

    Milovanović Milić

    2015-01-01

    Full Text Available Thomas Piketty’s international best selling Capital in the Twenty-First Century lays out his theory of a long-run rise in income inequality under capitalism. It is written as a manifesto urging reintegration of social sciences. A number of reviewers judged it on ideological grounds, labeling it either as a revolution in economic thinking, or dismissing it offhandedly. Piketty’s theory of rising inequality is based on the two Fundamental Laws of Capitalism, developed after the Solow growth model. However, this model is inconsistent with Piketty’s own characterization of modern capitalism. Moreover, his sole justification for the constant discrepancy between rate of return and rate of income growth (r > g is based on the high elasticity of substitution between capital and labor. However, that is just one factor that can have an influence on factor income shares. By failing to offer a consistent theory of rising inequality, his piece can hardly be considered as a useful founding stone for a new social science.

  2. The nuclear Thomas-Fermi model

    International Nuclear Information System (INIS)

    Myers, W.D.; Swiatecki, W.J.

    1994-08-01

    The statistical Thomas-Fermi model is applied to a comprehensive survey of macroscopic nuclear properties. The model uses a Seyler-Blanchard effective nucleon-nucleon interaction, generalized by the addition of one momentum-dependent and one density-dependent term. The adjustable parameters of the interaction were fitted to shell-corrected masses of 1654 nuclei, to the diffuseness of the nuclear surface and to the measured depths of the optical model potential. With these parameters nuclear sizes are well reproduced, and only relatively minor deviations between measured and calculated fission barriers of 36 nuclei are found. The model determines the principal bulk and surface properties of nuclear matter and provides estimates for the more subtle, Droplet Model, properties. The predicted energy vs density relation for neutron matter is in striking correspondence with the 1981 theoretical estimate of Friedman and Pandharipande. Other extreme situations to which the model is applied are a study of Sn isotopes from 82 Sn to 170 Sn, and the rupture into a bubble configuration of a nucleus (constrained to spherical symmetry) which takes place when Z 2 /A exceeds about 100

  3. Improved thomas formula for radon measurement

    International Nuclear Information System (INIS)

    Ji Changsong

    1991-06-01

    The FT 648 type portable absolute radon meter has been developed and the designing principle of this instrument is introduced. The absolute radon meter differs from relative radon meter. By using structure parameters, operating parameters and readout of this instrument, the radon content of measured gas is obtained directly without calibration in advance. Normally, the calibration is done by a standard radioactive gaseous source of which the radon concentration is known. The systematic error is removed by adding filter-efficiency Σ, α self-absorption correction β, energy spectrum correction S, geometric factor Ω of probe and gravity dropping correction factor G to the Thomas formula for radon measurement of two-filter method. The atmosphere radon content, which is given in hour-average, in Beijing area was measured by FT 648 type absolute radon meter. The measurement lasted continuously for several days and nights and a 'saddle shape' of radon content-time curve was observed. The day's average radon content was 8.5 Bq·m -3

    Thomas J. Ahrens, a leader in the study of high-pressure shock wave and planetary impact phenomena, died at his home in Pasadena, Calif., on 24 November 2010 at the age of 74. He was the California Institute of Technology's Fletcher Jones Professor of Geophysics, emeritus since 2005 but professionally active to the end. He had been president of AGU's Tectonophysics section, editor of Journal of Geophysical Research, founding member of both the Mineral and Rock Physics and Study of the Earth's Deep Interior focus groups, and editor—more like key driving force—for AGU's Handbook of Physical Constants. Tom was a pioneer in experimental and numerical studies of the effects of projectiles hitting a target at velocities exceeding the speed of sound (hypervelocity impact), arguably the most important geophysical process in the formation, growth, and, in many cases, surface evolution of planets. As a professor at Caltech, he established the foremost university laboratory for shock wave experiments, where students and research associates from around the world pursued basic research in geophysics, planetary science, and other disciplines. Previously, high-pressure shock experiments were conducted primarily in national laboratories, where they were initially associated with the development of nuclear weapons.

    2016-08-01

    The aim of this study was to assess the contributions of Thomas Waters's work in the field of health care ergonomics and beyond. Waters's research of safe patient handling with a focus on reducing musculoskeletal disorders (MSDs) in health care workers contributed to current studies and prevention strategies. He worked with several groups to share his research and assist in developing safe patient handling guidelines and curriculum for nursing students and health care workers. The citations of articles that were published by Waters in health care ergonomics were evaluated for quality and themes of conclusions. Quality was assessed using the Mixed Methods Appraisal Tool and centrality to original research rating. Themes were documented by the type of population the citing articles were investigating. In total, 266 articles that referenced the top seven cited articles were evaluated. More than 95% of them were rated either medium or high quality. The important themes of these citing articles were as follows: (a) Safe patient handling is effective in reducing MSDs in health care workers. (b) Shift work has negative impact on nurses. (c) There is no safe way to manually lift a patient. (d) Nurse curriculums should contain safe patient handling. The research of Waters has contributed significantly to the health care ergonomics and beyond. His work, in combination with other pioneers in the field, has generated multiple initiatives, such as a standard safe patient-handling curriculum and safe patient-handling programs. © 2016, Human Factors and Ergonomics Society.

  6. Thomas Edison’s Poetry Machine

    Directory of Open Access Journals (Sweden)

    Matthew Rubery

    2014-04-01

    Full Text Available The tradition of spoken-word recording began with Thomas Edison’s invention of the phonograph. Hence, this article makes the case that 1878 is a more important year to the history of literature than has yet been recognized for its experiments with verse and sound-recording technology. Although the tinfoil phonograph’s first decade has been well documented by media historians, literary critics have singled out 1888 as the noteworthy year since that is when Edison’s improved phonograph made it possible to record prominent figures including Alfred Tennyson and Robert Browning. Taking Edison’s original tinfoil phonograph as an alternative starting point reveals how the 1878 phonograph demonstrations, despite technological limitations, undertook acoustic experiments that enabled audiences to discern new forms of meaning, pleasure, and pathos in even the most well-known material. The recordings considered here include ‘Mary Had a Little Lamb’ as well as scripts by Tennyson, Caroline Norton, Edgar Allan Poe, Shakespeare, and others. Such recitals illustrate the extent to which Edison’s talking machine influenced the reception of texts while at the same time giving rise to performances unheard of in previous cultures.

  9. Electron-electron Thomas peak in fast transfer ionization

    Tolmanov, S. G.; McGuire, J. H.

    2000-01-01

    ''Thomas process'' is a name used for a family of singular two-step processes that can lead to electron transfer. The Thomas process of the ''second kind,'' occurring in reactions with both transfer and ionization, utilizes the e-e scattering in the second step, so this Thomas process requires the dynamics of the electron-electron interaction. We calculate numerically the second order element of an S matrix and corresponding cross sections for the transfer ionization process. We find that the position and shape of the Thomas peak depend on both electron-electron and the electron-nucleus interaction. Also the direct and exchange amplitudes are equal at the peak position. We test the peaking approximation used for transfer ionization. Our results can be compared to experimental results for p + +He→H+He 2+ +e - . (c) 2000 The American Physical Society

    Faussurier, Gérald

    2017-11-01

    We investigate the relativistic finite-temperature Thomas-Fermi model, which has been proposed recently in an astrophysical context. Assuming a constant distribution of protons inside the nucleus of finite size avoids severe divergence of the electron density with respect to a point-like nucleus. A formula for the nuclear radius is chosen to treat any element. The relativistic finite-temperature Thomas-Fermi model matches the two asymptotic regimes, i.e., the non-relativistic and the ultra-relativistic finite-temperature Thomas-Fermi models. The equation of state is considered in detail. For each version of the finite-temperature Thomas-Fermi model, the pressure, the kinetic energy, and the entropy are calculated. The internal energy and free energy are also considered. The thermodynamic consistency of the three models is considered by working from the free energy. The virial question is also studied in the three cases as well as the relationship with the density functional theory. The relativistic finite-temperature Thomas-Fermi model is far more involved than the non-relativistic and ultra-relativistic finite-temperature Thomas-Fermi models that are very close to each other from a mathematical point of view.

    A jacking mechanism for raising the upper internals structure of a liquid metal nuclear reactor which jacking mechanism uses a system of gears and drive shafts to transmit force from a single motor to four mechanically synchronized ball jacks to raise and lower support columns which support the upper internals structure. The support columns each have a pin which rides in a slot in a housing fixed to the reactor head. The pin has two locking plates which can be rotated around the pin to bring the locking plates into engagement with the housing in a raised or a lowered position of the support column such that the support column is then supported by the locking plate and not by the ball screw jacks.

    We study the error threshold of topological color codes on Union Jack lattices that allow for the full implementation of the whole Clifford group of quantum gates. After mapping the error-correction process onto a statistical mechanical random three-body Ising model on a Union Jack lattice, we compute its phase diagram in the temperature-disorder plane using Monte Carlo simulations. Surprisingly, topological color codes on Union Jack lattices have a similar error stability to color codes on triangular lattices, as well as to the Kitaev toric code. The enhanced computational capabilities of the topological color codes on Union Jack lattices with respect to triangular lattices and the toric code combined with the inherent robustness of this implementation show good prospects for future stable quantum computer implementations.

  2. An experimental study of the mechanism of failure of rocks under borehole jack loading

    Van, T. K.; Goodman, R. E.

    1971-01-01

    Laboratory and field tests with an experimental jack and an NX-borehole jack are reported. The following conclusions were made: Under borehole jack loading, a circular opening in a brittle solid fails by tensile fracturing when the bearing plate width is not too small. Two proposed contact stress distributions can explain the mechanism of tensile fracturing. The contact stress distribution factor is a material property which can be determined experimentally. The borehole tensile strength is larger than the rupture flexural strength. Knowing the magnitude and orientation of the in situ stress field, borehole jack test results can be used to determine the borehole tensile strength. Knowing the orientation of the in situ stress field and the flexural strength of the rock substance, the magnitude of the in situ stress components can be calculated. The detection of very small cracks is essential for the accurate determination of the failure loads which are used in the calculation of strengths and stress components.

    Full Text Available Nella prolusione al suo corso al Collège de France, pronunciata il 6 aprile 2006, Thomas Pavel si interroga sugli aspetti emotivi ed etici dell'attività della lettura, sull'“abbandonarsi” di chi legge all'opera letteraria. Come avviene la trasfigurazione del quotidiano nel mondo finzionale? Come si svolge il processo di identificazione dell'io nell'opera? Lo studioso rintraccia il fondamento di tale processo nella non coincidenza di principio tra io e vita, quindi nella facoltà del lettore di accogliere e riconoscere il senso dell'opera. Un senso che tuttavia non si palesa una volta per tutte nella sua interezza e trasparenza, ma che diviene oggetto di continuo dialogo fra i lettori, un senso quindi affidato alle loro cure.During the opening lecture of his course at Collège de France, held on April 6th 2006, Thomas Pavel talks about the emotional and ethical aspects of reading and about «completely surrending» to literature. How is everyday life transfigured into poetic invention? How is our ego identified in the literary work? The scholar traces the origin of this process to the radically different principles governing ego and life. Because of this, the reader is able to grasp and understand the real meaning of the book. This, however, is never completely revealed in a clear way. Instead, it becomes the object of a never-ending dialogue among the readers: it is therefore their care the meaning is entrusted to.Во вступлении к своему курсу лекций во Французском Колледже, произнесенном 6-го апреля 2006-го года, Томас Павел размышляет о эмоциональных и этических сторонах чтения, о том, как читатель «отдается» литературному произведению.

    Baseball maintains one of the highest impact injury rates in all athletics. A principal causative factor is the "beanball," referring to a pitch thrown directly at a batter's head. Frequent morbidities elicited demand for the development of protective gear development in the 20th century. In this setting, Dr. Walter Dandy was commissioned to design a "protective cap" in 1941. His invention became widely adopted by professional baseball and inspired subsequent generations of batting helmets. As a baseball aficionado since his youth, Walter Dandy identified a natural partnership between baseball and medical practice for the reduction of beaning-related brain injuries. This history further supports the unique position of neurosurgeons to leverage clinical insights, inform innovation, and expand service to society.

  10. Jacking mechanism for upper internals structure of a liquid metal nuclear reactor

    International Nuclear Information System (INIS)

    Gillett, J.E.; Wineman, A.L.

    1984-01-01

    A jacking mechanism is described for raising the upper internals structure of a liquid metal nuclear reactor which jacking mechanism uses a system of gears and drive shafts to transmit force from a single motor to four mechanically synchronized ball jacks to raise and lower support columns which support the upper internals structure. The support columns have a pin structure which rides up and down in a slot in a housing fixed to the reactor head. The pin has two locking plates which can be rotated around the pin to bring bolt holes through the locking plates into alignment with a set of bolt holes in the housing, there being a set of such housing bolt holes corresponding to both a raised and a lowered position of the support column. When the locking plate is so aligned, a surface of the locking plate mates with a surface in the housing such that the support column is then supported by the locking plate and not by the ball jacks. Since the locking plates are to be installed and bolted to the housing during periods of reactor operation, the ball jacks need not be sized to react the large forces which occur or potentially could occur on the upper internals structure of the reactor during operation. The locking plates react these loads. The ball jacks, used only during refueling, can be smaller, which enable conventionally available equipment to fulfill the precision requirements for the task within available space

    2007-12-01

    The astronomy community lost a good friend when Tom Metcalf was killed in a skiing accident on Saturday, 7 July 2007, in the mountains near Boulder, Colorado. Tom was widely known for prolific work on solar magnetic fields, hard-X-ray imaging of solar flares, and spectral line diagnostics. He was often characterized as "one of the nicest guys in science." Born October 5, 1961 in Cheverly, Maryland, to Fred and Marilyn, Thomas R. Metcalf joined his sister, Karen, two years his elder, in a close family that loved sailing, inquisitiveness, and the natural world. Sibling rivalry (usually a Tonka truck intruding on Barbie's sub-table "castle") melted when Tom and Karen collaborated on elaborately engineered room-sized blanket-forts. Tom confidently signed up at age of three to crew for his family's sailboat; when the family moved to California in 1966, as Tom's father took a Professor of Mathematics position at the University of California Riverside, Tom's love for sailing was well-established. Week-long cruises or short trips in the harbor were all fun; when school friends came aboard, it was even better--if "only slightly too crowded" from the adults' points of view. Tom's introduction to astronomy began one cold, very clear, December night in the early 1970s, on a family camping trip to Death Valley. The "Sidewalk Astronomers of San Francisco" had lined the sidewalk near the visitors' center with all sorts of telescopes for public viewing. Soon after, Tom and his boyhood friend Jim O'Linger were building their own scopes, attending "Amateur Telescope Makers" conferences, and Tom was setting up his scope on a sidewalk for public viewing. In 1986, Tom set up his telescope on the bluffs above Dana Point Harbor, and gave numerous strangers a stunning view of Halley's Comet. His interest in physics and mathematics became evident during Tom's last years in high school (Poly High in Riverside), and as a senior he qualified to take freshman Physics at the University of

    Over the years, I've daydreamed about stealing a Vermeer, a Picasso, or Rembrandt. It tickles me, as much as watching the reboot of The Thomas Crown Affair. Why is it, do you suppose, so much fun to think about stealing a world renowned piece off the wall of a major metropolitan museum? Is it the romantic thoughts of getting away with it, walking past infrared detectors, and pressure sensors ala Indiana Jones with the sack of sand to remove the idol without triggering the security system? Is it the idea of snatching items with such fantastic prices, where the romance of possessing an item of such value is less intoxicating than selling it to a private collector for it to never be seen again? I suspect others share my daydreams as they watch theater or hear of a brazen daylight heist at museums around the world, or from private collections. Though when reality sets in, the mind of the security professional kicks in. How could one do it, why would one do it, what should you do once it's done? The main issue a thief confronts when acquiring unique goods is how to process or fence them. They become very difficult to sell because they are one-of-a-kind, easy to identify, and could lead to the people involved with the theft. The whole issue of museum security takes up an ironic twist when one considers the secretive British street artist 'Banksy'. Banksy has made a name for himself by brazenly putting up interesting pieces of art in broad daylight (though many critics don't consider his work to be art) on building walls, rooftops, or even museums. I bring him up for a interesting take on what may become a trend in museum security. In March of 2005, Banksy snuck a piece of his called 'Vandalized Oil Painting' into the Brooklyn Museum's Great Historical Painting Wing, plus 3 other pieces into major museums in New York. Within several days, 2 paintings had been torn down, but 2 stayed up much longer. In his home country of the UK, a

    Physiological changes during pregnancy affect routine tests for iron deficiency. The reticulocyte haemoglobin equivalent (RET-He) and serum-soluble transferrin receptor (sTfR) assay are newer diagnostic parameters for the detection of iron deficiency, combined in the Thomas diagnostic plot. We used this plot to determine the iron status of pregnant women presenting for their first visit to an antenatal clinic in Bloemfontein, South Africa. Routine laboratory tests (serum ferritin, full blood count and C-reactive protein) and RET-He and sTfR were performed. The iron status was determined using the Thomas plot. For this study, 103 pregnant women were recruited. According to the Thomas plot, 72.8% of the participants had normal iron stores and erythropoiesis. Iron-deficient erythropoiesis was detected in 12.6%. A third of participants were anaemic. Serum ferritin showed excellent sensitivity but poor specificity for detecting depleted iron stores. HIV status had no influence on the iron status of the participants. Our findings reiterate that causes other than iron deficiency should be considered in anaemic individuals. When compared with the Thomas plot, a low serum ferritin is a sensitive but nonspecific indicator of iron deficiency. The Thomas plot may provide useful information to identify pregnant individuals in whom haematologic parameters indicate limited iron availability for erythropoiesis. © 2015 John Wiley & Sons Ltd.

    Vivien Thomas (1910-1985) was an African-American scientist, pioneer, and renowned educator. Thomas's contributions to cardiovascular surgery were unequivocal, and yet it was only after his death that he gained more widespread recognition. Thomas's more notable work involves aiding in the discovery of the cause of traumatic shock, designing and guiding the first operation to treat Tetralogy of Fallot, carrying out the first atrial septectomy, and helping develop the electrical defibrillator. Thomas struggled amidst the adversities of racism and the Great Depression (1929-1941), armed merely with a high school degree. Nevertheless, his genius and determination eventually led him to receive an honorary doctorate from John Hopkins University. His story inspired the creation of the award winning PBS documentary in 2003 Partners of the Heart and also the 2004 Emmy Award-winning HBO film Something the Lord Made. This article will aim to provide an overview to the more notable events in Thomas's amazing tale, with a particular focus on his work on the Tetralogy of Fallot.

    2004-12-01

    Thomas M. Donahue, one of the nation's leading space and planetary scientists and a pioneer of space exploration, died Saturday October 16, 2004, from complications following heart surgery. The Edward H. White II Distinguished University Professor of Planetary Science at the University of Michigan, Tom shaped space exploration through his scientific achievements and policy positions. His work started with the first use of sounding rockets following World War II and continued for almost 60 years. Tom was born in Healdton, Oklahoma on May 23, 1921 to Robert Emmet and Mary (Lyndon) Donahue. His father was a plumber in the oil fields when Tom was born (Healdton OK was an oil town) and worked as a plumber in Kansas City for a time. Tom grew up in Kansas City, graduating in 1942 from Rockhurst College in that city with degrees in classics and physics. His graduate work in physics at Johns Hopkins University was interrupted by service in the Army Signal Corps. He obtained his PhD degree in atomic physics from Hopkins in the fall of 1947. After three years as a post-doctoral research associate and assistant professor at Hopkins, Tom joined the University of Pittsburgh Physics Department in 1951. At Pittsburgh he organized an atomic physics and atmospheric science program that led to experimental and theoretical studies of the upper atmosphere of the Earth and other solar system planets with instruments flown on sounding rockets and spacecraft. He became Professor of Physics in 1959 and eventually Director of the Laboratory for Atmospheric and Space Sciences and the Space Research Coordination Center at the University. In 1960 he spent a sabbatical year on a Guggenheim Fellowship at the Service d'Aeronomie in Paris, which began collaborations with French colleagues that flourished for more than 40 years. In 1974 he became the Chairman of the Atmospheric and Oceanic Science Department, University of Michigan, a position he held until 1981. In 1986, he was named the Henry

    Two corrections to the Thomas-Fermi theory of atoms are studied. First the correction for exchange, that is the effect of the Pauli principle in the interaction energy, is considered. The defining variational problem is non-convex and standard technique to prove existence of a minimizing solution do not apply. Existence and uniqueness of solutions are established by convexifying or relaxing the energy functional. Properties of the minimizing solution are studied. A second correction due to von Weizsaecker is also discussed. Finally the dual principle to the Thomas-Fermi variational problem is studied (only in the neutral case). A dual principle is suggested for the ionic case. Also, a review of recent rigorous results concerning Thomas-Fermi theory is presented

    Thomas J. Ahrens, a leader in the use of shock waves to study planetary interiors and impact phenomena, died at his home in Pasadena, California on November 24, 2010, at the age of 74. He was the California Institute of Technology's Fletcher Jones Professor of Geophysics, formally emeritus since 2005 but professionally active to the end. Tom was a pioneer in experimental and numerical studies of the effects of hypervelocity impact, arguably the most important geophysical process in the formation, growth and - in many cases - surface evolution of planets. As a professor at Caltech, he established the foremost university laboratory for shock wave experiments, where students and research associates from around the world pursued basic research in geophysics, planetary science and other disciplines. Previously, high-pressure shock experiments were primarily conducted in national laboratories, where they were initially associated with development of nuclear weapons. The shock wave laboratory at Caltech was noted for key measurements addressing major questions in planetary geophysics. Equation-of-state studies on silicate melts showed that magma deep in Earth's mantle could be denser than the coexisting crystals, implying downward transport of melts (and associated heat) rather than the upward eruption of lavas observed in volcanic regions at Earth's surface. Shock-melting experiments on iron at pressures of Earth's core provide a crucial constraint on the temperature at the center of our planet. And studies of hydrous, carbonate and sulphate minerals under shock compression document how climate-altering molecules can be released by major impacts, such as the K/T event associated with the most recent mass extinction of biota in Earth history. In addition, Tom was a leader in numerical simulation of cratering, bringing the most recent laboratory measurements into the modeling of planetary impacts. Tom's training was in geophysics and applied experimental physics, as

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

    In the Thomas-Fermi approximation to theories of coupled fermions and scalars, the equations for spherically-symmetric non-topological solitons have the form of potential motion. This gives a straightforward method for proving the existence of non-topological solitons in a given theory and for finding the constant-density, saturating solutions

  7. An Analytical Method for Jack-Up Riser’s Fatigue Life Estimation

    Directory of Open Access Journals (Sweden)

    Fengde Wang

    2018-01-01

    Full Text Available In order to determine whether a special sea area and its sea state are available for the jack-up riser with surface blowout preventers, an analytical method is presented to estimate the jack-up riser’s wave loading fatigue life in this study. In addition, an approximate formula is derived to compute the random wave force spectrum of the small-scale structures. The results show that the response of jack-up riser is a narrow band random vibration. The infinite water depth dispersion relation between wavenumber and wave frequency can be used to calculate the wave force spectrum of small-scale structures. The riser’s response mainly consists of the additional displacement response. The fatigue life obtained by the formula proposed by Steinberg is less than that of the Bendat method.

    Directory of Open Access Journals (Sweden)

    Bassam M. Al-Shraah

    2017-11-01

    Full Text Available This paper aims to sketch out the transformation that Jack Burden—the main character in the novel—had gone through. With all the political leanings in Warren’s All the king’s Men, Jack burden seems to have had developed his own theories of dealing with life and people all through his life. He has always suffered an inferiority complex, rendering himself unworthy of being a real human being. This paper claims that Jack’s philosophical transformation has passed through three distinct phases; he had changed from a carefree idealist to a man of moral responsibility much similar to a Bildungsroman style of character maturation. Difficult times that Jack Burden has gone through caused his awakening at the end of the novel ushering his maturation

  9. Purification, crystallization and preliminary X-ray analysis of urease from jack bean (Canavalia ensiformis)

    International Nuclear Information System (INIS)

    Balasubramanian, Anuradha; Ponnuraj, Karthe

    2009-01-01

    Jack bean urease was purified and crystallized and X-ray diffraction data were collected to 2.05 Å resolution. Plant urease is a seed protein that is common in most legumes. It is also common in many bacteria and fungi and several species of yeast. Urease allows organisms to use exogenous and internally generated urea as a nitrogen source by catalyzing the hydrolysis of urea to ammonia and carbon dioxide. Urease from jack bean meal was purified to electrophoretic homogeneity using a series of steps involving acetone precipitation and size-exclusion and ion-exchange chromatography. The jack bean urease was crystallized and the resulting crystals diffracted to 2.05 Å resolution using synchrotron radiation. The crystals belonged to the hexagonal space group P6 3 22, with unit-cell parameters a = b = 138.57, c = 198.36 Å

  10. Spin-singlet quantum Hall states and Jack polynomials with a prescribed symmetry

    Estienne, Benoit; Bernevig, B. Andrei

    2012-01-01

    We show that a large class of bosonic spin-singlet Fractional Quantum Hall model wavefunctions and their quasihole excitations can be written in terms of Jack polynomials with a prescribed symmetry. Our approach describes new spin-singlet quantum Hall states at filling fraction ν=(2k)/(2r-1) and generalizes the (k,r) spin-polarized Jack polynomial states. The NASS and Halperin spin-singlet states emerge as specific cases of our construction. The polynomials express many-body states which contain configurations obtained from a root partition through a generalized squeezing procedure involving spin and orbital degrees of freedom. The corresponding generalized Pauli principle for root partitions is obtained, allowing for counting of the quasihole states. We also extract the central charge and quasihole scaling dimension, and propose a conjecture for the underlying CFT of the (k,r) spin-singlet Jack states.

  11. Obituary: Thomas Gold, 1920-2004

    Science.gov (United States)

    Dermott, Stanley F.

    2004-12-01

    Thomas "Tommy" Gold died of heart disease at Cayuga Medical Center, Ithaca NY on 22 June 2004 at the age of 84. He will be remembered as one of the most interesting, dynamic and influential scientists of his generation. Tommy's paradigm-changing ideas in astronomy and planetary science, while original and bold, were also highly controversial. With his radical work on the origin of natural gas and petroleum, the controversy is likely to continue. Tommy was born in Vienna, Austria on 22 May 1920, moving with his family to Berlin at age 10 and then, after the rise of Hitler in 1933, to England. His parents were Josephine (nee Martin) and Maximillian Gold, a successful steel magnate. Tommy was educated at Zuoz College in Switzerland where he became an expert skier and developed an athletic prowess that he maintained throughout his life, winning a NASTAR gold medal for skiing at the age of 65. He studied Mechanical Sciences at Trinity College, Cambridge, but much to his disgust his education was interrupted because of internment by the British as a suspected enemy alien. That unfortunate period (I remember him saying to me "Can you believe the stupidity, interring people like me who had fled from Nazi Germany?") had one good outcome: on his first night in camp he met Hermann Bondi who had an important influence on his early development as a scientist. They were both born in Vienna, their parents knew each other, and they were fellow students at Trinity, but this was their first meeting. On release, he went immediately into top-secret radar research for the British Admiralty, working as a team with Bondi and Fred Hoyle in a farm cottage in Dunsfold, Surrey. Tommy's first published research, which was a Nature paper with R.J. Pumphrey in 1947, was not in astronomy but physiology. He applied his engineer's understanding of positive feedback to develop and test a resonance model for how the human ear determines pitch. His conclusion that pitch discrimination occurs

    New daily persistent headache (NDPH) is an idiopathic headache syndrome characterized by the abrupt onset of an unremitting, daily, continuous headache without an antecedent escalating headache pattern, and not attributable to other primary or secondary headache disorders. We review the history of NDPH in terms of its characterization and classification, and then interview Dr. Walter Vanast, the neurologist who initially described NDPH three decades ago, to gain his perspective now that there is more widespread recognition and interest in this syndrome. © 2017 American Headache Society.

Since then Scott and other advocates walked the floor at Parliament House (home of the Faculty of Advocates and the Court of Session waiting to be hired. Scott’s own experiences as a fledgling advocate are echoed in those of Alain Fairford in his novel Redgauntlet (Scott 1824, which provides a vivid picture of Parliament House in the eighteenth century. During his life, Scott combined extensive writing and editing issues with his daily work as Clerk of Session and Sheriff-Depute of Selkirkshire. Walter Scott was not unaware of Justice and Law and The Heart of Mid-Lothian is the novel in which he introduces to the reader the Scottish Legal System during the eighteenth century. However, there are few more examples that I will explain. Aunque Sir Walter Scott es un conocido escritor, la mayoría de sus lectores saben que en 1792 se hizo abogado, cuando fue admitido en el colegio de abogados. Desde entonces Scott y otros abogados rondaron el Parlamento con la esperanza de ser contratados.

    2014-01-01

    Walter Álvarez Quispe, a Kallawaya healer and biomedical practitioner specializing in general surgery and gynecology, presents the struggle of traditional and alternative healers to get their Andean medical systems depenalized between 1960 and 1990. Bolivia was the first country in Latin America and the Caribbean to decriminalize traditional medicine before the proposals of the International Conference on Primary Health Care (Alma-Ata, 1978). The data provided by the interviewee show that the successes achieved, mainly by the Kallawayas, stem from their own independent initiative. These victories are not the result of official policies of interculturality in healthcare, although the successes achieved tend to be ascribed to them.

  12. Psychosurgery, ethics, and media: a history of Walter Freeman and the lobotomy.

    Science.gov (United States)

    Caruso, James P; Sheehan, Jason P

    2017-09-01

    At the peak of his career, Walter J. Freeman II was a celebrated physician and scientist. He served as the first chairman of the Department of Neurology at George Washington University and was a tireless advocate of surgical treatment for mental illness. His eccentric appearance, engaging personality during interviews, and theatrical demonstrations of his surgical techniques gained him substantial popularity with local and national media, and he performed more than 3000 prefrontal and transorbital lobotomies between 1930 and 1960. However, poor patient outcomes, unfavorable portrayals of the lobotomy in literature and film, and increased regulatory scrutiny contributed to the lobotomy's decline in popularity. The development of antipsychotic medications eventually relegated the lobotomy to rare circumstances, and Freeman's reputation deteriorated. Today, despite significant advancements in technique, oversight, and ethical scrutiny, neurosurgical treatment of mental illness still carries a degree of social stigma. This review presents a historical account of Walter Freeman's life and career, and the popularization of the lobotomy in the US. Additionally, the authors pay special attention to the influence of popular literature and film on the public's perception of psychosurgery. Aided by an understanding of this pivotal period in medical history, neurosurgeons are poised to confront the ethical and sociological questions facing psychosurgery as it continues to evolve.

    The lateral jack-knife position is often used during transpsoas surgery to improve access to the spine. Postoperative neurological signs and symptoms are very common after such procedures, and the mechanism is not adequately understood. The objective of this study is to assess if the lateral jack-knife position alone can cause neurapraxia. This study compares neurological status at baseline and after positioning in the 25° right lateral jack-knife (RLJK) and the right lateral decubitus (RLD) position. Fifty healthy volunteers, ages 21 to 35, were randomly assigned to one of 2 groups: Group A (RLD) and Group B (RLJK). Motor and sensory testing was performed prior to positioning. Subjects were placed in the RLD or RLJK position, according to group assignment, for 60 minutes. Motor testing was performed immediately after this 60-minute period and again 60 minutes thereafter. Sensory testing was performed immediately after the 60-minute period and every 15 minutes thereafter, for a total of 5 times. Motor testing was performed by a physical therapist who was blinded to group assignment. A follow-up call was made 7 days after the positioning sessions. Motor deficits were observed in the nondependent lower limb in 100% of the subjects in Group B, and no motor deficits were seen in Group A. Statistically significant differences (p knife positioning for 60 minutes results in neurapraxia of the nondependent lower extremity. Our results support the hypothesis that jack-knife positioning alone can cause postoperative neurological symptoms.

    Full Text Available Pasak bumi (Eurycoma longifolia Jack is one of non timber forest products with “indeterminate” conservation status and commercially traded in West Kalimantan. The research objective was to determine the potential of pasak bumi root per hectare and its ecological condition under natural habitat. Root weight of E. longifolia Jack was estimated using simple linear regression and exponential equation with stem diameter and height as independent variables. The results showed that the individual number of the population was 114 with the majority in seedling stage with 71 individuals (62.28%. The distribution was found in clumped pattern. Conditions of the habitat could be described as follows: daily average temperature of 25.6oC, daily average relative humidity of 73.6%, light intensity of 0.9 klx, and red-yellow podsolic soil with texture ranged from clay to sandy clay. The selected estimator model for E. longifolia Jack root weight used exponential equation with stem height as independent variable using the equation of Y= 21.99T0,010 and determination coefficient of 0.97. After height variable was added, the potential of E. longifolia Jack minimum root weight that could be harvested per hectare was 0.33 kg.Keywords: Eurycoma longifolia, habitat preference, distribution pattern, root weight

    2008-08-01

    In situ Li analyses of 4348 to 3362 Ma detrital zircons from the Jack Hills, Western Australia by SIMS reveal that the Li abundances (typically 10 to 60 ppm) are commonly over 10,000 times higher than in zircons crystallized from mantle-derived magmas and in mantle-derived zircon megacrysts (typically Jack Hills zircons also have fractionated lithium isotope ratios ( δ7Li = - 19 to + 13‰) about five times more variable than those recorded in primitive ocean floor basalts (2 to 8‰), but similar to continental crust and its weathering products. Values of δ7Li below - 10‰ are found in zircons that formed as early as 4300 Ma. The high Li compositions indicate that primitive magmas were not the source of Jack Hills zircons and the fractionated values of δ7Li suggest that highly weathered regolith was sampled by these early Archean magmas. These new Li data provide evidence that the parent magmas of ancient zircons from Jack Hills incorporated materials from the surface of the Earth that interacted at low temperature with liquid water. These data support the hypothesis that continental-type crust and oceans existed by 4300 Ma, within 250 million years of the formation of Earth and the low values of δ7Li suggest that weathering was extensive in the early Archean.

    2014-04-01

    Full Text Available Adequate soil management can create favorable conditions to reduce erosion and water runoff, consequently increase water soil recharge. Among management systems intercropping is highly used, especially for medium and small farmers. It is a system where two or more crops with different architectures and vegetative cycles are explored simultaneously at the same location. This research investigated the effects of maize intercropped with jack bean on soil losses due to water erosion, estimate C factor of Universal Soil Losses Equation (USLE and how it can be affected by soil coverage. The results obtained also contribute to database generation, important to model and estimate soil erosion. Total soil loss by erosion caused by natural rain, at Lavras, Minas Gerais, Brazil, were: 4.20, 1.86, 1.38 and 1.14 Mg ha-1, respectively, for bare soil, maize, jack bean and the intercropping of both species, during evaluated period. Values of C factor of USLE were: 0.039, 0.054 and 0.077 Mg ha Mg-1 ha-1 for maize, jack bean and intercropping between both crops, respectively. Maize presented lower vegetation cover index, followed by jack beans and consortium of the studied species. Intercropping between species showed greater potential on soil erosion control, since its cultivation resulted in lower soil losses than single crops cultivation, and this aspect is really important for small and medium farmers in the studied region.

    Among the technologies used to recuperate cadmium (Cd) contaminated soils, phytoextraction are particularly important, where the selection of suitable plants is critical to the success of the soil remediation. Thus, the objectives of this study were to evaluate the responses of jack-bean and sorghum to Cd supply and to quantify Cd accumulation by these species grown in hydroponic culture. The plants were subjected to 0, 15, 30, or 60 μmol Cd L(-1) in the nutrient solution, and gas exchange, plant growth and Cd accumulation were measured at 25 days after starting Cd treatments. The Cd supply severely reduced growth of shoots and roots in both species. In jack-bean, Cd decreased photosynthesis by 56-86%, stomatal conductance by 59-85% and transpiration by 48-80%. The concentrations and amounts of Cd accumulated in the plant tissues were proportional to the metal supply in the nutrient solution. Sorghum was more tolerant than jack-bean to Cd toxicity, but the latter showed a greater metal concentration and accumulation in the shoot. Therefore, jack-bean would be more suitable than sorghum for use in Cd phytoremediation programs based on phytoextraction.

    We compare the Bakamjian-Thomas (BT) formulation of relativistic few-body systems with light-front field theories that maintain closer contact with Feynman diagrams. We find that Feynman diagrams distinguish Melosh rotations and other kinematical quantities belonging to various composite subsystem frames that correspond to different loop integrals. The BT formalism knows only the rest frame of the whole composite system, where everything is evaluated. (author)

  20. Safety Performance Improvement for Nuclear Power Plants Utilizing THOMAS

    International Nuclear Information System (INIS)

    2005-01-01

    THOMAS (Thermal Hydraulics Online Monitoring Advisory System) is equipped with a couple of salient features compared with existing monitoring systems. The first has to do with the three-dimensional (3D) visualization technique to support the nuclear power plant (NPP) operators and personnel using the virtual reality (VR) technology. VR depicts an environment simulated by a computer. Most of the VR environments primarily include visual experiences, displayed either on a monitor or though special stereoscopic goggles. Users can often interactively manipulate a VR environment, either through standard input devices like a keyboard, or through specially designed devices like a cybergloves. Additional devices were not applied the in THOMAS. The visualized model file is brought to the VR space from the computer-aided design (CAD) tool. In the VR space, using mapping, the component color is changed with linked value of the safety variables. Operators thus can easily recognize the plant condition. This is related with the human factor engineering. The second is the function of decision making using the influence diagram logic. The influence diagram logic is based on the total probability and Bayesian theory. The accident modeling is rooted in the emergency operating procedure (EOP). The final goal of this system is, in the accident situation, to present a success path to the operator for the recovery of the NPP system. At the current developing level, the database signals THOMAS. In other words, a spectrum of system analysis codes provides the safety parameter values to the database, which are subsequently supplied to THOMAS through the network

    Aruncus dioicus (Walter) Fernald is an herbaceous plant belonging to the Rosaceae family. In the northern regions of Italy young shoots of A. dioicus are collected and used as vegetable. No studies on the chemical composition of young shoots of A. dioicus have been reported so far. Thus, the aim of the present paper was to develop and validate a comprehensive chromatographic method allowing the identification and quantification of chemical compounds occurring in A. dioicus shoots harvested at different developmental stages. The results showed that shoots contain mainly polyphenols. Twenty-four compounds were detected. Caffeoylglucose derivatives were recognized as major compounds. It was also confirmed that shoots contain the cyanogenic compound prunasin at all investigated vegetation stages. It was shown that the prunasin content significantly increases during plant development, thus justifying the belief that after the development of the first green leaves, shoots should not be used for culinary purposes any longer.

    With the announcement by William Lennox at the 1935 London International Neurology Congress of the use of electroencephalography in the study of epilepsy, it became evident that a new and powerful technique for the investigation of seizures had been discovered. William Grey Walter, a young researcher finishing his post-graduate studies at Cambridge, was selected to construct and study the EEG in clinical neurology at the Maudsley Hospital, London. His hugely productive pioneering career in the use of EEG would eventually lead to groundbreaking work in other fields --the emerging sciences of robotics, cybernetics, and early work in artificial intelligence. In this historical note his pioneering work in the fields of clinical neurophysiology is documented, both in the areas of epileptology and tumour detection. His landmark contributions to clinical neurophysiology are worthy of documentation.

    In 1926-1927, a graduate student, B. C. Graves, working with Stanford University psychologist Walter Miles and legendary football coach Pop Warner, conducted an investigation of variations in signal calling as they affected the charging times of football players. The study was one of two that involved Miles and the ingenious multiple chronograph that he had invented to time the reactions of seven players simultaneously. These studies represented a brief digression in the career of Miles, who certainly was no sport psychologist. They tell of an interesting collaboration between scientist and coaches that produced one of the richest studies in sport psychology in the first half of the twentieth century.

    Inequalities arise as an essential component in various mathematical areas. Besides forming a highly important collection of tools, e.g. for proving analytic or stochastic theorems or for deriving error estimates in numerical mathematics, they constitute a challenging research field of their own. Inequalities also appear directly in mathematical models for applications in science, engineering, and economics. This edited volume covers divers aspects of this fascinating field. It addresses classical inequalities related to means or to convexity as well as inequalities arising in the field of ordinary and partial differential equations, like Sobolev or Hardy-type inequalities, and inequalities occurring in geometrical contexts. Within the last five decades, the late Wolfgang Walter has made great contributions to the field of inequalities. His book on differential and integral inequalities was a real breakthrough in the 1970’s and has generated a vast variety of further research in this field. He also organize...

This leads to initiation of discourses over behavior or actions which may not be unethical but which may be questionable in terms of social propriety. Moreover, the “shocking” may be seen as persistent attempts at formulation of subjectivity -the “performative self.” These ideas are analyzed with reference to Foucault's perspective on the issues and briefly in context of the late Victorian Aesthete culture spearheaded by Walter Pater and later, Oscar Wilde, the quintessential “dandy.” Their texts Marius the Epicurean and The Picture of Dorian Gray are read with the question of ethics and hedonism in mind, also relating the same to their fascination with classical Epicureanism.     Keywords: Aesthetics; Ethics; Pater; Wilde; Shocking; Surveillance; Foucault; Epicureanism.

    Stephen Hall, a freelance science writer and science-communication teacher, received the Walter Sullivan Award for Excellence in Science Journalism-Features at the AGU Fall Meeting Honors Ceremony, held on 5 December 2012 in San Francisco, Calif. Hall was honored for the article "At Fault?" published 15 September 2011 in Nature. The article examines the legal, personal, and political repercussions from a 2009 earthquake in L'Aquila, Italy for seismologists who had attempted to convey seismic risk assessments to the public. The 6.3 magnitude quake devastated the medieval town and caused more than 300 deaths. Six scientists and one government official were subsequently convicted of manslaughter and sentenced to prison for inadequately assessing and mischaracterizing the risks to city residents, despite the inexact nature of seismic risk assessment. The Sullivan award is for work published with a deadline pressure of more than 1 week.

    Full Text Available A comparative study Biodiversity is not a static phenomenon and many variables have an effect on accelerated biodiversity loss. While most of the variables affecting biodiversity loss are caused by humankind, many species are affected by more than one variable simultaneously. Six fundamental causes for biodiversity loss have been identifi ed, namely unsustainable population growth and associated increased pressure on natural resources; a reduced spectrum of agricultural, forestry and fishery products; failure of economic systems to attach appropriate economic value to the environment and resources; inequality in ownership, flow and management of the benefits and utilisation of resources; insufficient knowledge in the application and use of resources; and legislation and institutional systems that promote unsustainable abuse of the environment (Middleton 2003:250. The worldwide loss of biodiversity makes the management of protected areas more important than ever. Protected areas are under increasing pressure to become economically viable and independent of state grants. Tourism creates the mechanism and opportunities for protected areas to increase their economic viability while advancing the appreciation of nature. The management of these protected areas therefore includes the management of visitors. South Africa is the third most bio diverse country in the world. Amongst a variety of nature conservation endeavours nine national botanical gardens are managed by the South African National Biodiversity Institute (SANBI. One of the nine national gardens is the Walter Sisulu National Botanical Garden situated in Roodekrans towards the west of Johannesburg. A study was launched to determine preferences of visitors to the Walter Sisulu National Botanical Garden by making use of semi-structured interviews. The purpose of the study was threefold. Firstly the study was launched to determine whether visitors to the garden had an increased awareness

    1998-01-01

    The Rayleigh-Taylor instability of two superposed electrically conducting Walters elastico-viscous fluids (Model B') of uniform densities when the whole system is immersed in a uniform horizontal magnetic field has been studied. The stability analysis has been carried out, for mathematical simplicity, for two highly viscoelastic fluids of equal kinematic viscosities and equal kinematic viscoelasticities. For the stable configuration as in hydrodynamic case, the system is found to be stable or unstable for the wave-number range k (2v') -12 depending on kinematic viscoelasticity v'. For the unstable configuration, the magnetic field has got stabilizing effect and completely stabilizes certain wave-number range which was always unstable in the absence of magnetic field. The behaviour of growth rates with respect kinematic viscosity and kinematic viscoelasticity parameters are examined analytically. (author)

    Full Text Available In his cognitive model called “mithological machine”, Furio Jesi proposes to circumscribe the concept of “myth” by means of a technique of critical composition of data and doctrines about the myth and the mythology. The model not only seeks to brave scientific-methodological reasons but also ethical-political ones. It’s about avoiding all the evocation and instrumentalization of myth in view of a political interest. This work analyzes the way as the model of Jesi resumes and develops two motives of Walter Benjamin’s work: (1 the one known as method of the quote without quotation marks and (2 the criticism of the reactionary theories of myth, specifically regarding the rehabilita­tion of Bachofen in the German culture from 1920’s and 1930’s.

    Use of the World Wide Web (WWW) and electronic media to facilitate medical care has been the subject of many reports in the popular press. However, few reports have documented the results of implementing electronic health portals for essential medical tasks, such as prescription refills and appointments. At Walter Reed Army Medical Center, "Search & Learn" medical information, Internet-based prescription refills and patient appointments were established in January 2001. A multiphase retrospective analysis was conducted to determine the use of the "Search & Learn" medical information and the relative number of prescription refills and appointments conducted via the WWW compared with conventional methods. From January 2001 to May 2002, there were 34,741 refills and 819 appointments made over the Internet compared with 2,275,112 refills and approximately 500,000 appointments made conventionally. WWW activity accounted for 1.52% of refills and 0.16% of appointments. There was a steady increase in this percentage over the time of the analysis. In April of 2002, the monthly average of online refills had risen to 4.57% and online appointments were at 0.27%. Online refills were projected to account for 10% of all prescriptions in 2 years. The "Search & Learn" medical information portion of our web site received 147,429 unique visits during this same time frame, which was an average of 326 visitors per day. WWW-based methods of conducting essential medical tasks accounted for a small but rapidly increasing percentage of total activity at Walter Reed Army Medical Center. Subsequent phases of analysis will assess demographic and geographic factors and aid in the design of future systems to increase use of the Internet-based systems.

    Metasediments of the Jack Hills contain the oldest known terrestrial minerals in the form of zircons nearly 4.4 billion years old. Paleointensity data from these zircons provide evidence for a Hadean geodynamo as old as 4.2 billion years old. Given the importance of these zircons for constraining the earliest history of the core, it is vital to understand the fidelity of the zircon record. A fundamental aspect providing context for the preservation of primary magnetic signals is the nature of overprints predicted to have been imparted on rocks of the Jack Hills due to Archean to Proterozoic metamorphic events. To be viable magnetic records of a Hadean geodynamo, zircon magnetization directions should differ from these secondary magnetizations. To evaluate these secondary magnetizations, we report paleomagnetic analyses of a comprehensive sampling of 68 quartzite cobble-sized clasts from the Jack Hills metasediments ∼0.5 to 1.0 km from the Discovery Site (which has yielded the oldest zircons and paleofield estimates). While application of standard paleomagnetic tests suggests that the ensemble of cobble directions cannot be distinguished from those drawn from a random distribution, a new cluster analysis of directions on a sphere and non-parametric resampling approaches reveal significant directions amongst subsets of the data. One, isolated at the lowest temperature analyzed [200 to 300 °C, Declination (Dec.) = 316.8°, Inclination (Inc.) = - 51.1 °] appears to be dominated by the present day field. Another, isolated at higher (but still relatively low unblocking temperatures that we call "intermediate", of ∼350-500 °C, Dec. = 243.8°, Inc. = 9.5°) agrees with a magnetic overprint isolated from the secondary Cr-Fe mica fuchsite isolated from the Jack Hills Discovery site, passing a field test at the 80% confidence level. No evidence is found in our data, or in the data of others collected on similar Jack Hills lithologies, for a widespread 1 Ga

    Sharing one's own immersive experience over the Internet is one of the ultimate goals of telepresence technology. In this paper, we present JackIn Head, a visual telepresence system featuring an omnidirectional wearable camera with image motion stabilization. Spherical omnidirectional video footage taken around the head of a local user is stabilized and then broadcast to others, allowing remote users to explore the immersive visual environment independently of the local user's head direction. We describe the system design of JackIn Head and report the evaluation results of real-time image stabilization and alleviation of cybersickness. Then, through an exploratory observation study, we investigate how individuals can remotely interact, communicate with, and assist each other with our system. We report our observation and analysis of inter-personal communication, demonstrating the effectiveness of our system in augmenting remote collaboration.

    Eberhardt, L.E.; Van Voris, P.

    1986-08-01

    In an effort to determine whether US Army activities on the Dugway Proving Ground (DPG) have had an impact on resident wildlife, intensive studies have been conducted on the biology and ecology of the black-tailed jack rabbit (Lepus californicus) since 1965. in addition, the incidence of endemic diseases in several species of resident wildlife on the DPG have been studied from the late 1950s through the mid-1970s. The objectives of this report are to: (1) compile and summarize the jack rabbit data and some of the disease information that is presently contained only in annual reports; (2) compare the DPG jack rabbit data to data available on other jack rabbit populations; and (3) analyze the data for unusual or unexplained fluctuations in population densities or in incidence of disease.

    The cutting off column and jacking technology is a method for increasing story height, which has been widely used and paid much attention in engineering. The stiffness will be changed after the process of cutting off column and jacking, which directly affects the overall seismic performance. It is usually necessary to take seismic strengthening measures to enhance the stiffness. A five story frame structure jacking project in Jinan High-tech Zone was taken as an example, and three finite element models were established which contains the frame model before lifting, after lifting and after strengthening. Based on the stiffness, the dynamic time-history analysis was carried out to research its seismic performance under the EL-Centro seismic wave, the Taft seismic wave and the Tianjin artificial seismic wave. The research can provide some guidance for the design and construction of the entire jack lifting structure.

    2010-01-01

    In the present article, the 'pasta' phase is studied at finite temperatures within a Thomas-Fermi (TF) approach. Relativistic mean-field models, both with constant and density-dependent couplings, are used to describe this frustrated system. We compare the present results with previous ones obtained within a phase-coexistence description and conclude that the TF approximation gives rise to a richer inner ''pasta'' phase structure and the homogeneous matter appears at higher densities. Finally, the transition density calculated within TF is compared with the results for this quantity obtained with other methods.

    Eigenvectors have been calculated for the A=18, 19, 20, 21, and 26 nuclei in an sd shell basis. The decomposition of these states into their shell model components shows, in agreement with other recent work, that this distribution is not a single Gaussian. We find that the largest amplitudes are distributed approximately in a Gaussian fashion. Thus, many experimental measurements should be consistent with the Porter-Thomas predictions. We argue that the non-Gaussian form of the complete distribution can be simply related to the structure of the Hamiltonian

    We use the continuum shell model approach to explore the resonance width distribution in unstable many-body systems. The single-particle nature of a decay, the few-body character of the interaction Hamiltonian, and the collectivity that emerges in nonstationary systems due to the coupling to the continuum of reaction states are discussed. Correlations between the structures of the parent and daughter nuclear systems in the common Fock space are found to result in deviations of decay width statistics from the Porter-Thomas distribution.

    British sociologists have long been interested in youth sub-cultures. However British sociologists have tended to focus on working class subcultures and avoided engagement with exclusive sub-cultures of elite social groups. This article seeks to attend to this gap by examining the subculture of a British elite: ex-public school students at select universities in the UK in the twenty-first century. This group consists of a relatively small group of young adults, aged between 18 and 23, who attended public schools, especially one of the nine Clarendon schools (Eton, Winchester, Westminster, St. Paul's, Merchant Taylor's, Shrewsbury, Rugby, Harrow and Charterhouse), and were students at a selective group of British universities, primarily Oxford and Cambridge, Durham, Bristol, Exeter, Bath, Manchester, St Andrews and Edinburgh. The article examines the way in which this group has reconfigured and re-constituted itself in the face of globalizing challenges. Specifically, it examines the way in which participation of ex-public school students in events run by and under the patronage of the high street retailing company, Jack Wills, has played a galvanising role for this group in the last decade. The Jack Wills crowd is an example of how some young adults form exclusive social networks and reproduce prevailing forms of privilege. The social networks built around the Jack Wills subculture is likely to provide them with advantages in the job market through a prodigious network of connections and patrons.

    The main objective of this study was to assess the influence of slaughter methods on the quality of Chilean jack mackerel (Trachurus murphyi) during refrigerated storage on board. Fishes were slaughtered by asphyxia in air (AA), asphyxia in ice water (AI) or stunning fish heads (SH), and the rigor mortis, pH, total volatile basic nitrogen (TVB-N), trimethylamine (TMA), 2-thiobarbituric acid reactive substances (TBARS) and sensory properties for the fishes were analyzed. On day 0, Chilean jack mackerel samples of AI group displayed higher pH values than those of AA and SH groups. TVB-N, TMA and TBARS values of all samples increased with the storage time, and these values of AI had a lower increase than AA and SH. Moreover, samples of AI had a better sensory score than AA and SH during storage. It can be concluded that slaughter method of asphyxia in ice water for Chilean jack mackerel exhibit the better efficiency on maintaining the fish quality during refrigerated storage on board.

    This study evaluated failure probabilities of jack up units on the framework of time dependent reliability analysis using uncertainty from different sea states representing different return period of the design wave. Surface elevation for each sea state was represented by Karhunen-Loeve expansion method using the eigenfunctions of prolate spheroidal wave functions in order to obtain the wave load. The stochastic wave load was propagated on a simplified jack up model developed in commercial software to obtain the structural response due to the wave loading. Analysis of the stochastic response to determine the failure probability in excessive deck displacement in the framework of time dependent reliability analysis was performed by developing Matlab codes in a personal computer. Results from the study indicated that the failure probability increases with increase in the severity of the sea state representing a longer return period. Although the results obtained are in agreement with the results of a study of similar jack up model using time independent method at higher values of maximum allowable deck displacement, it is in contrast at lower values of the criteria where the study reported that failure probability decreases with increase in the severity of the sea state.

    Recent shell model calculations have yielded width amplitude distributions which have apparently not agreed with the Porter-Thomas distribution.

A reanalysis of these calculations suggests that, although correct, they do not imply that the Porter-Thomas distribution will fail to describe the width distributions observed experimentally. The conditions for validity of the Porter-Thomas distribution are discussed

  3. Jack Polynomials as Fractional Quantum Hall States and the Betti Numbers of the ( k + 1)-Equals Ideal

    Science.gov (United States)

    We show that for Jack parameter α = -( k + 1)/( r - 1), certain Jack polynomials studied by Feigin-Jimbo-Miwa-Mukhin vanish to order r when k + 1 of the coordinates coincide. This result was conjectured by Bernevig and Haldane, who proposed that these Jack polynomials are model wavefunctions for fractional quantum Hall states. Special cases of these Jack polynomials include the wavefunctions of Laughlin and Read-Rezayi. In fact, along these lines we prove several vanishing theorems known as clustering properties for Jack polynomials in the mathematical physics literature, special cases of which had previously been conjectured by Bernevig and Haldane. Motivated by the method of proof, which in the case r = 2 identifies the span of the relevant Jack polynomials with the S n -invariant part of a unitary representation of the rational Cherednik algebra, we conjecture that unitary representations of the type A Cherednik algebra have graded minimal free resolutions of Bernstein-Gelfand-Gelfand type; we prove this for the ideal of the ( k + 1)-equals arrangement in the case when the number of coordinates n is at most 2 k + 1. In general, our conjecture predicts the graded S n -equivariant Betti numbers of the ideal of the ( k + 1)-equals arrangement with no restriction on the number of ambient dimensions.

  4. Instantons, quivers and noncommutative Donaldson-Thomas theory

    2011-12-01

    We construct noncommutative Donaldson-Thomas invariants associated with abelian orbifold singularities by analyzing the instanton contributions to a six-dimensional topological gauge theory. The noncommutative deformation of this gauge theory localizes on noncommutative instantons which can be classified in terms of three-dimensional Young diagrams with a colouring of boxes according to the orbifold group. We construct a moduli space for these gauge field configurations which allows us to compute its virtual numbers via the counting of representations of a quiver with relations. The quiver encodes the instanton dynamics of the noncommutative gauge theory, and is associated to the geometry of the singularity via the generalized McKay correspondence. The index of BPS states which compute the noncommutative Donaldson-Thomas invariants is realized via topological quantum mechanics based on the quiver data. We illustrate these constructions with several explicit examples, involving also higher rank Coulomb branch invariants and geometries with compact divisors, and connect our approach with other ones in the literature.

A concepção de Evangelho de Cristo como um reino de outro mundo, a natureza privada da fé, o pontificado do soberano como aquele que se posiciona está entre Deus e os homens, a união entre Lei Mosaica e Lei Natural e a união entre Igreja e Estado são os delimitadores do grande tema, que busca levar o leitor contemporâneo ao conhecimento das conclusões de Hobbes e, assim, considerar a aplicação das mesmas a sua geração.

  6. Some notes on time dependent Thomas Fermi approximation

    International Nuclear Information System (INIS)

    Holzwarth, G.

    1979-01-01

    The successful use of effective density-dependent potentials in static Hartree-Fock calculations for nuclear ground-state properties has led to the question whether it is possible to obtain significant further simplification by approximating also the kinetic energy part of the ground state energy by a functional of the local density alone. The great advantage of such an approach is that its complexity is independent of particle number; the size of the system enters only through parameters, Z and N. The simple 'extended Thomas Fermi' functionals are based on the assumption of a spherically symmetric local Fermi surface throughout the nucleus and they represent the 'liquid drop' part of the static total energy. Given this static formalism which is solved directly for the local density without considering individual particles one might ask for a possible dynamical extension in the same sense as TDHF is a dynamical extension of the static HF approach. The aim of such a Time Dependent Thomas Fermi (TDTF) approximation would be to determine directly the time-dependent local single-particle density from given initial conditions and the single-particle current density without following each particle on its individual orbit

    Full Text Available This article discusses women position in society that Thomas Hardy portrays in his short story entitled The Withered Arm. This short story tells about two female character have closerelationship to the same man. The man comes from upper class. The first woman from lower class has a son of his, but they do not live together. Then, the second one is his new young wife. This short story takes rural area, Dorset as the setting of place where the society has intimate relationships and setting of time is in Victorian era. It applied feminism theory that focuses on male and female positions in society. Beauvoir (1949 considered that the male in French and Western societies defines what it means to be human and what it means to be female. The female becomes subordinate to the male. It applies qualitative analysis method. The text is analyzed relating to the female characters‘ position in society. Their positions make them get discrimination which society created. Thomas Hardy‘s short story will be analyzed on discrimination to female characters. The data shows that the two female characters are oppressed on their conditions. Although they do not get physical harassment, the oppression comes from social injustice that women do not get equal benefit and opportunities. Both of them survive to obtain what they need. These characters use their ways as the survivors because of unfair condition.

    We construct noncommutative Donaldson-Thomas invariants associated with abelian orbifold singularities by analyzing the instanton contributions to a six-dimensional topological gauge theory. The noncommutative deformation of this gauge theory localizes on noncommutative instantons which can be classified in terms of three-dimensional Young diagrams with a colouring of boxes according to the orbifold group. We construct a moduli space for these gauge field configurations which allows us to compute its virtual numbers via the counting of representations of a quiver with relations. The quiver encodes the instanton dynamics of the noncommutative gauge theory, and is associated to the geometry of the singularity via the generalized McKay correspondence. The index of BPS states which compute the noncommutative Donaldson-Thomas invariants is realized via topological quantum mechanics based on the quiver data. We illustrate these constructions with several explicit examples, involving also higher rank Coulomb branch invariants and geometries with compact divisors, and connect our approach with other ones in the literature.

  9. Vigencia de algunas de las ideas mercantilistas de Thomas Mun

    2011-01-01

    Full Text Available Generalmente cuando se aborda el mercantilismo se hace referencia a la acumulación de oro y plata, una balanza de pagos favorable o a la política económica de Jean Colbert. Pero poco se ha hablado del papel y condiciones necesarias del comerciante como agente que hizo posible que los primeros Estados-Nación se convirtieran en las futuras potencias económicas del mundo occidental. Thomas Mun fue uno de aquellos escritores mercantilistas que destacó el papel del comerciante en el auge del sistema mercantilista. El estudio de sus ideas permite concluir que sus recomendaciones acerca de lo que debería ser un comerciante de éxito siguen vigentes hoy en día. La razón de tal afirmación estriba en que sus recomendaciones eran adecuadas en un marco en que se estaba presentando una transformación significativa del sistema de organización comercial con la presencia de la Joint-Stock Company. Independientemente de que muchas de las funciones que Thomas Mun le atribuía al comerciante hoy en día son especializadas, su dominio sigue siendo la clave del éxito de una política comercial que emprenda cualquier nación.

  10. Thomas Willis: the faculties and his two cognitive frameworks.

    Science.gov (United States)

    McNabb, Jody

    2014-11-01

    Thomas Willis' 1664 study The anatomy of the brain is widely regarded as one of the first clinical studies of the brain. In Theanatomy, Thomas Willis explicitly connected the cognitive faculties and the nerves. Willis' later, 1672 work, The two discourses concerning the soul of brutes, severely undermined the materialism of Willis' first study: he affirmed dualism and cognitive immateriality; changed the anatomical locations of cognition; and reasserted a division between the rational and sensitive souls. His exact motive to return to orthodoxy is unclear, but contemporary scholarship of Willis has compounded the confusion with by relying predominantly on The soul of brutes instead of The anatomy. We trace Willis' career and examine his methodological practices, which help explain the historical practices and pressures. A closer examination of Willis' Anatomy of the brain reveals a much more materialistic account of the brain, the faculties, and nervous system. In this article, we present our own analysis of Willis' concept of rationality in the Anatomy and explain its importance for nervous physiology and understanding the analytic techniques for first defining faculty localizations. We then explain the role of the imagination and the immortal soul in the rearticulated anatomical concepts from The soulof brutes. Copyright © 2014 Elsevier Inc. All rights reserved.

    2016-03-01

    Full Text Available All philosophers, beginning with the pre-Socratics, through Plato and Aristotle, and up to Thomas Aquinas, accepted as a certain that the world as a whole existed eternally. The foundation for the eternity of the world was the indestructible and eternal primal building material of the world, a material that existed in the form of primordial material elements (the Ionians, in the form of ideas (Plato, or in the form of matter, eternal motion, and the first heavens (Aristotle. The article outlines the main structure of the philosophical theory of creation ex nihilo developed by St. Thomas Aquinas and indebted to his metaphysical thought. It shows the wisdom-based and ratiocinative foundation of the rational cognition of reality—reality that comes from the personal creative act of God. It concludes that the perception that the beings called to existence by the personal act of God the Creator are intelligible is the ultimate rational justification for the fact that our human cognition, love, and spiritual creativity are rational.

    Full Text Available The thermosolutal instability of compressible Walters' (model B' elastico-viscous rotating fluid permeated with suspended particles (fine dust in the presence of vertical magnetic field in porous medium is considered. By applying normal mode analysis method, the dispersion relation has been derived and solved analytically. It is observed that the rotation, magnetic field, suspended particles and viscoelasticity introduce oscillatory modes. For stationary convection the Walters' (model B' fluid behaves like an ordinary Newtonian fluid and it is observed that the rotation and stable solute gradient has stabilizing effects and suspended particles are found to have destabilizing effect on the system, whereas the medium permeability has stabilizing or destabilizing effect on the system under certain conditions. The magnetic field has destabilizing effect in the absence of rotation, whereas in the presence of rotation, magnetic field has stabilizing or destabilizing effect under certain conditions.

    lc-strain characteristic of YBCO coated conductor was measured using a Walters spring (WASP). In this technique, additional bending and thermal strains induced to the YBCO layer should be considered. In order to produce different initial bending strain to the YBCO layer, the conductor was wound around the springs with different diameters and in the different bending directions. The clear evidence was obtained that -strain curves using a WASP strongly depend on the initial bending strain state...

  19. The utopian challenge to global capitalism by Walter van den Broeck in Terug naar Walden

    Directory of Open Access Journals (Sweden)

    Andries Visagie

    2012-12-01

    Full Text Available The socialist sympathies that inform the writing of Flemish author Walter van den Broeck align him with a well-established tradition of socially engaged writing in Flanders. In his novel Terug naar Walden (Back to Walden, published in 2009, he revisits the Walden project of the Dutch reformer and writer Frederik van Eeden (1860−1932. Van den Broeck suggests that a reconsideration of the socialist ideals that inspired Van Eeden to establish settlements in the Netherlands and the United States is warranted in the light of the economic crisis triggered by unchecked capitalist practices in 2008. In Terug naar Walden Ruler Marsh, the richest man in the world, unleashes a global financial crisis as a form of retaliation against the capitalist system that ruined his parents. Marsh returns to the Kempen in Flanders where his family originated. In a Heideggerean affirmation of the local as exemplified by the country road, Van den Broeck articulates his vision of the common, that theorists Michael Hardt and Antonio Negri in their Empire trilogy have attempted to salvage from communist thinking, with a utopian notion that a stronger connection with the land and the people within one’s immediate environment may provide a useful premise for the development of viable alternatives to capitalism.

  20. Critica e derive del mito nell’opera di Walter Benjamin

    Directory of Open Access Journals (Sweden)

    Matteo Meloni

    2015-03-01

    Full Text Available La ri essione critica sul mito e sulle sue derive nel mondo moderno sono pre- senti in buona parte del pensiero benjaminiano. A cominciare dagli scritti di filosofia del linguaggio nei quali il mito biblico istituisce il fondamento ontologico della parola originaria, tra rifiuto della storia e messianismo, fino alle considerazioni sul diritto e sul concetto di destino nella società borghese. Ma è soprattutto nella critica letteraria che Benjamin espone le sue più brillanti intuizioni: dallo sprigionarsi delle forze primordiali della natura che, nelle Affinità elettive di Goethe, tra violenza del diritto e libertà etica, si impossessano dei personaggi, alla dialettica del “risveglio” con Proust e i surrealisti, e all’esperienza profonda della vie antérieur di Baudelaire. Così, senza mai distanziarsi dal radicamento della condizione storica del suo tempo e senza mai cadere in facile misticismo, Walter Benjamin ha acutamente ispezionato le tracce del mito nella modernità, auspicando con intelligenza la liberazione umana dalla schiavitù della barbarie contingenti.

  1. Alfred Walter Campbell and the visual functions of the occipital cortex.

    Science.gov (United States)

    Macmillan, Malcolm

    2014-07-01

    In his pioneering cytoarchitectonic studies of the human brain, Alfred Walter Campbell identified two structurally different areas in the occipital lobes and assigned two different kinds of visual functions to them. The first area, the visuosensory, was essentially on the mesial surface of the calcarine fissure. It was the terminus of nervous impulses generated in the retina and was where simple visual sensations arose. The second area, the visuopsychic, which surrounded or invested the first, was where sensations were interpreted and elaborated into visual perceptions. I argue that Campbell's distinction between the two areas was the starting point for the eventual differentiation of areas V1-V5. After a brief outline of Campbell's early life and education in Australia and of his Scottish medical education and early work as a pathologist at the Lancashire County Lunatic Asylum at Rainhill near Liverpool, I summarise his work on the human brain. In describing the structures he identified in the occipital lobes, I analyse the similarities and differences between them and the related structures identified by Joseph Shaw Bolton. I conclude by proposing some reasons for how that work came to be overshadowed by the later studies of Brodmann and for the more general lack of recognition given Campbell and his work. Those reasons include the effect of the controversies precipitated by Campbell's alliance with Charles Sherrington over the functions of the sensory and motor cortices. Copyright © 2012 Elsevier Ltd.

  2. Eurydice at Euston?: Walter Benjamin and Marc Augé Go Underground

    Directory of Open Access Journals (Sweden)

    Graeme Gilloch

    2014-01-01

    Full Text Available Taking as its point of departure Walter Benjamin’s repeatedly unsuccessful attempt to give spatial form to his past, this paper suggests that it is perhaps the contemporary French anthropologist, Marc Augé, who provides the most appropriate envisioning of a ‘map of memories’ in his brief writings on the Parisian métro system. For Augé, the labyrinthine subway network constitutes nothing less than a ‘memory machine’ in which lines and station names serve as mnemonics, recalling long-forgotten childhood encounters and experiences. Mirroring the cityscape above, places themselves unexplored, unknown, the serried toponyms of the métro become an incantation summoning forth the shades of the past. As Augé points out, those stations that provide opportunities to change lines are felicitously termed ‘correspondences’, a Baudelairean term that fascinated Benjamin and informed his key historiographical notion of the ‘dialectical image,’ the intersection and mutual illumination of past and present moments. For me, Augé’s highly suggestive reflections bring to mind my own memories of a London childhood around 1970. Looking at the London underground map today, I cannot but see the sites of many past meetings and partings, dots connected by lines forming complex figures, constellations of memory.

  4. Genetic Drift. The ancient Egyptian dwarfs of the Walters Art Museum.

    2010-10-01

    The ancient Egyptians left an impressive artistic legacy documenting many aspects of their society including the existence of dwarfs as highly valued members. In previous publications in the Journal, I discussed dwarfs and skeletal dysplasia in ancient Egypt. In this study, I examined the ancient Egyptian representations of dwarfs of the Walters Art Museum in Baltimore, Maryland. One of the highlights of the collection is a group of five ivory figurines from Predynastic Times (pre 3500-3100 BCE) depicting a couple, a man with a child, and two females. Representations from other periods include ordinary as well as dwarf deities. The dwarf gods, Bes and Ptah, are frequently depicted holding or biting snakes or standing on crocodiles symbolizing their ability to ward off dangers. A couple of statuettes from the Greco-Roman Period that, in contrast to earlier Egyptian Periods, depict harsh physical anomalies, twisted bodies, and facial pain. The artistic impression can be interpreted as either tragic or humorous. The grotesque depiction of dwarfs during the Greco-Roman Period in ancient Egypt is believed to be due to a greater infusion of Hellenistic influence. This study provides a microcosm of the legacy of dwarfs in ancient Egypt and supports the premise that dwarfs were accepted and integrated in the ancient Egyptian society, and with a few exceptions, their disorder was not depicted as a physical handicap.

    Full Text Available The authors analyze the 16 early writings that W. Benjamin wrote between the ages of 19 and 23, all of which relate to educative matters, and where the decisive influence of G. Wyneken is shown. The issues that the young Walter Benjamin addresses are also studied, such as idealism and youth culture, the necessity of reform in schools and universities and also in moral, aesthetic and religious education as well as in juvenile sexuality. However, the most important thing is that in these works one can find the constants that characterize the rest of his production, such as his individualism, his obsession with his own childhood experiences, his contradictions and thematic transitions, his interest in aesthetics and art, the complexity of his work, his agnosticism and his consideration of Judaism as a cultural element, and above all his critical sense and his vocation for criticism which starts to become evident. Somehow in these articles of educative content one can discover many of the constants of what will be the subsequent work of this author.

  6. Green leviathan? Thomas hobbes, joel bakan and Arnold schwarzenegger.

    Science.gov (United States)

    Evans, Robert G

    2007-02-01

    Thomas Hobbes postulates that men are driven by "a perpetual and restless desire of power after power, that ceaseth only in death." The miserable consequences of this drive for power and the competing "desire of ease and sensual delight" and "fear of death and wounds" lead them to establish and obey. Substituting "profit" for "power" yields a description of the modern corporation, but without the desires or fears of natural persons. Such "unnatural persons" lack the Hobbesian ground of obligation, yet have appropriated the privileges and protections of natural persons. They challenge or undermine the sovereign wherever it limits their profits. Governor Schwarzenegger's re-election in California, however, on a strong anti-CO(2) program, suggests a willingness by threatened natural persons to re-empower Leviathan.

Se muestra que presentan una consideración diferente de los factores extracientíficos, que tienen en la primera un peso explicativo mayor. Se propone que en 1957 Kuhn maneja una historiografía casuística, centrada en la revolución copernicana, y en 1962 una historiografía estructural, centrada en los rasgos invariantes de las revoluciones científicas. Se concluye que las diferencias entre las dos obras son lo suficientemente profundas como para no considerarlas expresión de una misma visión de la ciencia.

    The SPIRES database was created in the late 1960s to catalogue the high energy physics preprints received by the SLAC Library. In the early 1990s it became the first database on the web and the first website outside of Europe. Although indispensible to the HEP community, its aging software infrastructure is becoming a serious liability. In a joint project involving CERN, DESY, Fermilab and SLAC, a new database, INSPIRE, is being created to replace SPIRES using CERN's modern, open-source Invenio database software. INSPIRE will maintain the content and functionality of SPIRES plus many new features. I describe this evolution from the birth of SPIRES to the current day, noting that the career of Tony Thomas spans this timeline.

  11. Whistles, bells, and cogs in machines: Thomas Huxley and epiphenomenalism.

    Science.gov (United States)

    Greenwood, John

    2010-01-01

    In this paper I try to shed some historical light upon the doctrine of epiphenomenalism, by focusing on the version of epiphenomenalism championed by Thomas Huxley, which is often treated as a classic statement of the doctrine. I argue that it is doubtful if Huxley held any form of metaphysical epiphenomenalism, and that he held a more limited form of empirical epiphenomenalism with respect to consciousness but not with respect to mentality per se. Contrary to what is conventionally supposed, Huxley's empirical epiphenomenalism with respect to consciousness was not simply based upon the demonstration of the neurophysiological basis of conscious mentality, or derived from the extension of mechanistic and reflexive principles of explanation to encompass all forms of animal and human behavior, but was based upon the demonstration of purposive and coordinated animal and human behavior in the absence of consciousness. Given Huxley's own treatment of mentality, his characterization of animals and humans as "conscious automata" was not well chosen.

  12. "German Culture is where I am": Thomas Mann in Exile

    1982-09-01

    Full Text Available Thomas Mann in exile reacted like many writers expelled from Germany: totally irritated he tried to defend his own identity by claiming that he was still the leading representative of Germany. But about 1938 a process of dissociation from Germany started which led to sharp remarks on Germany in his The Beloved Returns , to his conviction that German culture was where he lived and to the acknowledgement of America as his new home. Traces of his experience of exile, and a late answer on his separation from Germany in 1933, however, are to be found even in his incompleted novel Felix Krull which seems to have turned the disgusting experience of exile into friendly mythological light.

  13. Thomas-Fermi theory for atomic nuclei revisited

    International Nuclear Information System (INIS)

    Centelles, M.; Schuck, P.; Vinas, X.

    2007-01-01

    The recently developed semiclassical variational Wigner-Kirkwood (VWK) approach is applied to finite nuclei using external potentials and self-consistent mean fields derived from Skyrme interactions and from relativistic mean field theory. VWK consists of the Thomas-Fermi part plus a pure, perturbative h 2 correction. In external potentials, VWK passes through the average of the quantal values of the accumulated level density and total energy as a function of the Fermi energy. However, there is a problem of overbinding when the energy per particle is displayed as a function of the particle number. The situation is analyzed comparing spherical and deformed harmonic oscillator potentials. In the self-consistent case, we show for Skyrme forces that VWK binding energies are very close to those obtained from extended Thomas-Fermi functionals of h 4 order, pointing to the rapid convergence of the VWK theory. This satisfying result, however, does not cure the overbinding problem, i.e., the semiclassical energies show more binding than they should. This feature is more pronounced in the case of Skyrme forces than with the relativistic mean field approach. However, even in the latter case the shell correction energy for e.g., 208 Pb turns out to be only ∼-6 MeV what is about a factor two or three off the generally accepted value. As an ad hoc remedy, increasing the kinetic energy by 2.5%, leads to shell correction energies well acceptable throughout the periodic table. The general importance of the present studies for other finite Fermi systems, self-bound or in external potentials, is pointed out

    Full Text Available To protect themselves against fall hazards in a slab-column frame, workers use the row of shoring jacks installed at 1 m from the edge as supports for on-site built guardrails. Inspectors of the Quebec Workers Compensation Board (Commission de la santé et de la sécurité du travail (CSST have expressed concern about the safety and compliance of these on-site built guardrails with the Quebec Safety Code for the Construction Industry (S-2.1, r.4. Some workers have also inquired if the shoring jack can be used as an anchor for a travel restraint system. The present study describes how an evaluation method and a test protocol have been used to verify if guardrails built on-site, with shoring jacks as supports, are safe and comply with the requirements of S-2.1, r.4 and if the shoring jack can be used as an anchor point for a travel restraint system. The results of the study show 1 guardrails built on site with shoring jacks as supports, are safe and comply with S-2.1, r.4 and 2 shoring jacks used as supports for guardrails must not be used as an anchor for a travel restraint system.Para la protección contra el peligro de caída en altura durante la ejecución de la estructura de un edificio, los trabajadores utilizan puntales acodalados a dos forjados y situados a 1 metro del borde de forjado como apoyo de las barandillas de seguridad.

    Full Text Available Background: To investigate the effect of Eurycoma longifolia Jack root extract on serum lipids in rats. Methods: Twenty-six mature male albino Wistar rats were used in this study. A group of 18 rats were fed a high fat and high cholesterol diet for 4 weeks, after which their lipid profile was compared to the control group, who were kept on a normal diet. The rats were then further divided into three groups, the Cf group that continued to feed on a high fat and cholesterol diet only, and group A and group B who continued on a high fat diet with the addition of 5 mg/kg and 10 mg/kg of Eurycoma longifolia Jack root extract respectively for 4 weeks. After the 4 week period, the rat's lipid profiles were analysed again. Results: Group A and B showed significant total cholesterol reduction when compared to the Cf group, 140 ± 7.23, 139.63 ± 7.95, 192.14 ± 8.96 mg/dL respectively (p < 0.001. The total cholesterol/HDL ratio in group A was 5 however there was a sharp increase in group B to a high-risk level of 9.2 indicating a significant drop in HDL levels. The LDL level increased significantly in both group A and B compared to the Cf group. Conclusions: Eurycoma longifolia Jack root extract is effective in lowering total cholesterol, however the dose needs to be adjusted to prevent an excessive decrease in HDL levels.

  16. Secondary vegetation succession on jack pine (Pinus banksiana) cutovers in northeastern Ontario, Canada

    Tiveau, Daniel

    2000-07-01

    The effects of different harvesting and site preparation methods on competing vegetation were studied in nine jack pine (Pinus banksiana) cutovers in northeastern Ontario, Canada. Six different treatments plus glyphosate herbiciding and no herbiciding were applied: 1) tree-length harvesting followed by trenching, and full-tree harvesting followed by five site preparations, 2) no site preparation, 3) trenching and 4) blading and compaction as well as blading followed by two planting densities, 5) 1.2m and 6) 2m. Competing vegetation was assessed preharvest and years 1, 2, 3, and 5 postharvest. Data was also available from nine juvenile sites as well as nine semimature sites. Data collection consisted of coverage values of each species as well as structural data for main life forms in height classes. Growth and health data of the planted jack pine seedlings were also available. The data was analyzed using detrended correspondence analysis (DCA), diversity indices and tabular analysis. Three years after the herbicide application there is no difference between the total coverage in the halfplots that have received herbiciding and those that have not, but an alteration of the relative abundance of species groups has developed; glyphosate herbiciding promotes grasses over shrubs. When no site preparation is applied, shrubs increase and compete with the seedlings, whose growth is cut in half compared to the ones that have been site prepared by trenching. Five years after blading, and blading plus compaction, there is still very little vegetation in the research plots, but there is no reduction of the survival rate and growth of the jack pine seedlings. More dense planting after this treatment leads to more competing vegetation, probably due to increased availability of moisture. Grasses do not seem to be affected by compaction and pioneer mosses are promoted by this treatment but compaction leads to a significant reduction of the total coverage of competing vegetation

    Full Text Available The vegetation of the Jack Scott Nature Reserve in the Central Bankenveld Veld Type is classified chiefly by the Braun-Blanquet Table Method. Habitat features, physiognomy, total floristic composition, differentiating species, woody plants and prominent grasses and forbs are presented for each community. Characterizing habitat features, in order of importance for the communities, are: exposure, soil texture, geology, slope, aspect, degree of rockiness and previous ploughing. The classification correlates well with the major physiographic and climatic variation in the Reserve and generally does not cut across main physiognomic types. The communities are potentially homogeneous management units.

    Pier Giovanni Adamo

    2016-05-01

    Full Text Available La poetica di F. Schlegel ha realizzato una storicizzazione della teoria dei generi letterari sostituendo alla dicotomia del classicismo tra forma e contenuto una distinzione tra forma e spirito, secondo cui i materiali linguistico-tematici rappresentano i precipitati di quest’ultimo. Riprendendo questa intuizione di P. Szondi, potremmo affermare che, nella modernità letteraria, l’ibridazione è il processo di transizione dei materiali attraverso le forme. Un’opera tanto esemplare quanto strutturalmente rilevante, nell’orizzonte dell’ibridazione, è Einbahnstraße di Walter Benjamin, dove i materiali più disparati sono combinati a modellare una forma innovativa. Vi si mescolano stilemi della poesia in prosa, narrazione diaristica, (antimetodo surrealista, satira e intuizioni filosofiche. L’unicità, d’altra parte, risiede innanzitutto nell’essenza metacritica del procedimento organizzativo del libro: il frammentismo sistematico è un’applicazione pratica della teoria allegorica del montaggio, descritta nell’Ursprung des deutschen Trauerspiels. Il saggio si propone di leggere il testo come «un taccuino a forma di strada», anche per indagarne il valore di prologo al Passagenwerk, nato dall’avida lettura del Paysan de Paris di Aragon: istituisce un confronto per rilevare, nell’affinità di fondo, la  diversità di approccio tra il pensatore tedesco e il surrealismo, distinguendo tecniche di assemblaggio e ruolo dell’immaginario nell’uso di pubblicità e altri oggetti metropolitani. L’intenzione di una simile analisi di Einbahnstraße è dimostrare che Benjamin combina modelli letterari (Baudelaire, Proust, Kraus su tutti con i nuovi linguaggi artistici e le strategie discorsive della stampa per creare un’«immagine dialettica» dell’esistenza nel XX secolo.Friedrich Schlegel’s poetics realized a historicisation of literary genres theory by replacing classicist dichotomy between form and content with a

    2018-06-01

    Walter B. Cannon (1871-1945), perhaps America's preeminent physiologist, volunteered for service with the Army Expeditionary Force (AEF) during World War I. He initially served with Base Hospital No. 5, a unit made up of Harvard clinicians, before moving forward to the front lines to serve at a casualty clearing station run by the British. During his time there, he performed research on wounded soldiers to understand the nature and causes of traumatic shock. Subsequently, Cannon performed animal experimentation on the causes of traumatic shock in the London laboratory of Dr. William Bayliss before being assigned to the AEF Central Medical Laboratory in Dijon, France, where he continued his experimental studies. During this time, he also developed and taught a curriculum on resuscitation of wounded soldiers to medical providers. Although primarily a researcher and teacher, Cannon also performed clinical duties throughout the war, serving with distinction under fire. After the war, Cannon wrote a monograph entitled Traumatic Shock (New York: Appleton, 1923), which encapsulated the knowledge that had been gained during the war, both from direct observation of wounded soldiers, as well as laboratory experimentation on the causes and treatment of traumatic shock. In his monograph, Cannon elucidates a number of principles concerning hemorrhagic shock that were later forgotten, only to be "rediscovered" during the current conflicts in Iraq and Afghanistan. This paper summarizes Cannon's wartime experiences and the knowledge gained concerning traumatic shock during World War I, with a comparison of current combat casualty care practices and knowledge to that which Cannon and his colleagues understood a century ago.

  5. Walter Baade: Father of the Two Stellar Populations and Pioneer Supernova Researcher

    Science.gov (United States)

    Osterbrock, D. E.

    2001-05-01

    Walter Baade was the great observational astronomer of the middle part of the past century. He lived and worked in Pasadena, where he ``discovered" the two stellar populations and did outstanding pioneer research on supernovae at Mount Wilson and Palomar Observatories from 1931 until 1959, when he returned to his native Germany, and died the following year. Baade was born in a little town in northwest Germany, and educated at Goettingen University, where he received his Ph.D. in 1919, just after the end of World War I. He got a research position at Hamburg Observatory, and quickly jumped into globular cluster and galactic structure work with its 40-in reflector, then the largest telescope in Europe. Baade recognized very early the great importance of the extremely rare ``highly luminous novae" which Heber D. Curtis and Knut Lundmark isolated in 1919-21. In 1929 Baade called these ``Hauptnovae" the key to measuring distances of faint galaxies. We call them supernovae today, a term he and Fritz Zwicky began using in 1932. Similarly Baade's first inkling that there was a spherically symmetric distribution of stars in our Galaxy, which he named Population II in his two great 1944 papers, came when he began picking up field RR Lyrae variables in 1926. Baade's research on the two stellar populations and supernovae was extremely important in opening up the whole fields of stellar and galactic evolution. His invited lectures at meetings and symposia, and his courses as a visiting professor inspired a whole generation of research astrophysicists. Baade's attractive personality made it possible for him to make his great discoveries in a land in which he was officially an enemy alien during World War II.

  6. Big Data and : Walter Lippmann and the fallacy of data privacy self-management

    Directory of Open Access Journals (Sweden)

    Jonathan A Obar

    2015-10-01

    Full Text Available In 1927, Walter Lippmann published The Phantom Public , denouncing the ‘mystical fallacy of democracy.’ Decrying romantic democratic models that privilege self-governance, he writes: “I have not happened to meet anybody, from a President of the United States to a professor of political science, who came anywhere near to embodying the accepted ideal of the sovereign and omnicompetent citizen.” Almost 90 years later, Lippmann’s pragmatism is as relevant as ever, and should be applied in new contexts where similar self-governance concerns persist. This paper does just that, repurposing Lippmann’s argument in the context of the ongoing debate over the role of the digital citizen in Big Data management. It is argued that proposals by the Federal Trade Commission, the White House and the US Congress, championing failed notice and choice privacy policy, perpetuate a self-governance fallacy comparable to Lippmann’s, referred to here as the fallacy of data privacy self-management . Even if the digital citizen had the faculties and the system for data privacy self-management, the digital citizen has little time for data governance. We desire the freedom to pursue the ends of digital production, without being inhibited by the means. We want privacy, and safety, but cannot complete all that is required for its protection. If it is true that the fallacy of democracy is similar to the fallacy of data privacy self-management, then perhaps the pragmatic solution is representative data management : a combination of non/for-profit digital dossier management via infomediaries that can ensure the protection of personal data, while freeing individuals from what Lippmann referred to as an ‘unattainable ideal.’

    Full Text Available O ensaio traz como base a crítica ao capitalismo, no que se refere aos efeitos negativos que ele impõe aos indivíduos, a partir dos estudos da primeira geração da Escola de Frankfurt. Analisar-se-á a história das ideias a partir de Walter Benjamin, Herbert Marcuse, Theodor Adorno e Max Horkheimer. Benjamin afirma que vive-se a perda da aura das obras de arte, já que a sua comercialização faz com que se perca a essência daquelas obras. Ademais, a imposição da novidade às obras e aos produtos consumidos representa uma ferramenta de manipulação do capitalismo, culminando na pobreza da experiência humana. Marcuse afirma que a sociedade vive o princípio do desempenho, que provoca modos de vida uniformizados, baseados numa concepção de trabalho e diversão homogêneos. Adorno propôs que o tempo livre provocava uma sensação de liberdade nos indivíduos, mas, na realidade, tratava-se do exercício de uma não liberdade, já que as formas de diversão seguiam à risca os padrões exigidos pelo capital. A partir do método adotado pela própria Teoria Crítica, afirma-se que a presente discussão teórica só se torna efetiva quando aplicada à prática, à sociedade atual.

    Full Text Available The mountain pine beetle (MPB; Dendroctonus ponderosae has recently expanded its range from lodgepole pine forest into the lodgepole × jack pine hybrid zone in central Alberta, within which it has attacked pure jack pine. This study tested the effects of water limitation on tree defense response of mature lodgepole and jack pine (Pinus contorta and Pinus banksiana trees in the field. Tree defense response was initiated by inoculation of trees with the MPB-associated fungus Grosmannia clavigera and measured through monoterpene emission from tree boles and concentration of defensive compounds in phloem, needles, and necrotic tissues. Lodgepole pine generally emitted higher amounts of monoterpenes than jack pine; particularly from fungal-inoculated trees. Compared to non-inoculated trees, fungal inoculation increased monoterpene emission in both species, whereas water treatment had no effect on monoterpene emission. The phloem of both pine species contains (--α-pinene, the precursor of the beetle’s aggregation pheromone, however lodgepole pine contains two times as much as jack pine. The concentration of defensive compounds was 70-fold greater in the lesion tissue in jack pine, but only 10-fold in lodgepole pine compared to healthy phloem tissue in each species, respectively. Water-deficit treatment inhibited an increase of L-limonene as response to fungal inoculation in lodgepole pine phloem. The amount of myrcene in jack pine phloem was higher in water-deficit trees compared to ambient trees. Beetles reared in jack pine were not affected by either water or biological treatment, whereas beetles reared in lodgepole pine benefited from fungal inoculation by producing larger and heavier female offspring. Female beetles that emerged from jack pine bolts contained more fat than those that emerged from lodgepole pine, even though lodgepole pine phloem had a higher nitrogen content than jack pine phloem. These results suggest that jack pine chemistry

    Overlapping decapeptide fragments of H. pylori urease subunit A (UreA) were synthesized and tested with polyclonal antibodies against Canavalia ensiformis (Jack bean) urease. The linear epitopes of UreA identified using the dot blot method were then examined using epitope mapping. For this purpose, series of overlapping fragments of UreA, frameshifted ± four amino acid residues were synthesized. Most of the UreA epitopes which reacted with the Jack bean urease polyclonal antibodies had been recognized in previous studies by monoclonal antibodies against H. pylori urease. Fragments 11 - 24, 21 - 33, and 31 - 42 were able to interact with the Jack bean urease antibodies, giving stable immunological complexes. However, the lack of recognition by these antibodies of all the components in the peptide map strongly suggests that a non-continuous (nonlinear) epitope is located on the N-terminal domain of UreA. © 2018 Wiley-VHCA AG, Zurich, Switzerland.

    Acid deposition may adversely affect northern forest ecosystems by increasing the concentration of metals in the soil solution. This study investigates the effects of ectomycorrhizal fungi on paper birch and jack pine seedlings exposed to elevated Cu, Ni or Al in sand culture. One of four mycorrhizal fungi, Scleroderma flavidum, was able to reduce Ni toxicity to the birch seedlings. It did this by reducing transport of Ni to the stems. None of the fungi affected Cu toxicity in birch. In separate experiments, jack pine seedlings were exposed to combinations of Al and Ca. Infection with Rhizopogon rubescens increased seedling susceptibility to Al. Seedlings inoculated with Suillus tomentosus showed a greater growth stimulation by Ca than uninoculated jack pines. Thus, for both tree species, the mycorrhizal association could alter the response of seedlings to high concentrations of certain metals, although this varied with fungal species. 8 references.

    Manuka honey (Leptospermum scoparium) exerts a strong antibacterial effect. Bacterial enzymes are an important target for antibacterial compounds. The enzyme urease produces ammonia and enables bacteria to adapt to an acidic environment. A new enzymatic assay, based on photometric detection of ammonia with ninhydrin, was developed to study urease activity. Methylglyoxal (MGO) and its precursor dihydroxyacetone (DHA), which are naturally present in manuka honey, were identified as jack bean urease inhibitors with IC 50 values of 2.8 and 5.0mM, respectively. Urease inhibition of manuka honey correlates with its MGO and DHA content. Non-manuka honeys, which lack MGO and DHA, showed significantly less urease inhibition. MGO depletion from manuka honey with glyoxalase reduced urease inhibition. Therefore, urease inhibition by manuka honey is mainly due to MGO and DHA. The results obtained with jack bean urease as a model urease, may contribute to the understanding of bacterial inhibition by manuka honey. Copyright © 2017 Elsevier Ltd. All rights reserved.

  12. Sneaker "jack" males outcompete dominant "hooknose" males under sperm competition in Chinook salmon (Oncorhynchus tshawytscha).

    In a variety of taxa, males deploy alternative reproductive tactics to secure fertilizations. In many species, small "sneaker" males attempt to steal fertilizations while avoiding encounters with larger, more aggressive, dominant males. Sneaker males usually face a number of disadvantages, including reduced access to females and the higher likelihood that upon ejaculation, their sperm face competition from other males. Nevertheless, sneaker males represent an evolutionarily stable strategy under a wide range of conditions. Game theory suggests that sneaker males compensate for these disadvantages by investing disproportionately in spermatogenesis, by producing more sperm per unit body mass (the "fair raffle") and/or by producing higher quality sperm (the "loaded raffle"). Here, we test these models by competing sperm from sneaker "jack" males against sperm from dominant "hooknose" males in Chinook salmon. Using two complementary approaches, we reject the fair raffle in favor of the loaded raffle and estimate that jack males were ∼1.35 times as likely as hooknose males to fertilize eggs under controlled competitive conditions. Interestingly, the direction and magnitude of this skew in paternity shifted according to individual female egg donors, suggesting cryptic female choice could moderate the outcomes of sperm competition in this externally fertilizing species.

    There is considerable evidence that biodiversity promotes multiple ecosystem functions (multifunctionality), thus ensuring the delivery of ecosystem services important for human well-being. However, the mechanisms underlying this relationship are poorly understood, especially in natural ecosystems. We develop a novel approach to partition biodiversity effects on multifunctionality into three mechanisms and apply this to European forest data. We show that throughout Europe, tree diversity is positively related with multifunctionality when moderate levels of functioning are required, but negatively when very high function levels are desired. For two well-known mechanisms, ‘complementarity' and ‘selection', we detect only minor effects on multifunctionality. Instead a third, so far overlooked mechanism, the ‘jack-of-all-trades' effect, caused by the averaging of individual species effects on function, drives observed patterns. Simulations demonstrate that jack-of-all-trades effects occur whenever species effects on different functions are not perfectly correlated, meaning they may contribute to diversity–multifunctionality relationships in many of the world's ecosystems.

    2016-02-01

    Full Text Available This paper deals with the construction of the postmodern identity of Jack Gladney, the main character in Don DeLillo’s White Noise (1985. Employing (postmodern, social psychology, and psychoanalytic theories of Zygmunt Bauman, Erich Fromm, Jean Baudrillard, and Gilles Lipovetsky, it analyzes the construction of Gladney’s character through his social roles as professor, husband, and consumer in the narrow sense of the word in order to deduce that his consumerist practices have spread to all aspects of his life. This reading reveals a new interpretation of Gladney’s fear of death; it shows that Gladney’s thanatophobia represents a consequence of his atheistic worldview. Namely, unable to find a haven in religion, he unsuccessfully seeks the meaning of life and death elsewhere, mainly in consumerism, which is identified as the source of his alienation from himself, people, and God. This paper suggests that numerous problems of postmodern life are caused by the lack of faith in God and proposes a conclusion that religion itself could be the answer to the difficulties faced by postmodern individuals with fragmented identities such as Jack Gladney.

    Thomas Alva Edison was an icon of American achievement who literally invented the 20th century. Although best known as the inventor of the electric light bulb, the phonograph, and motion pictures, he also left a lasting legacy via peripheral developmental applications, such as endoscopes. A review of published urologic writings about incandescent cystoscopes was cross-referenced to writings about or from Edison. Important events that allowed transference of technology from the Edison laboratory to clinical practice were emphasized. Edison was born in 1847 while Lincoln was serving in Congress; he died in 1931 when Hoover struggled with the Great Depression. Edison's life spanned the formative period of America that Henry Adams called the "coming of age." Edison received a Sprengel vacuum device in late 1879, and as usual, he was able to tweak the machine to better performance. For 5 days in October, 16 to 21, he improved the vacuum from 1/100,000 to 1/1,000,000 atm, and his first incandescent bulb burned softly. On December 21, 1879, he leaked the story to N.Y. Herald journalist Marshall Fox, and the world was notified of the light bulb. Special Christmas light visits started in Menlo Park just 4 days later. Edison patented the screw cap for easy changes, and the first bulbs sold for 40 cents (cost $1.40). 100,000 bulbs sold in 1882, 4 million by 1892, and 45 million in 1903. Immediately, competitors and specialty manufacturers entered the market. Dr. Henry Koch and Charles Preston in Rochester, N.Y., developed a smaller, low amperage bulb that could be fitted to medical devices. No discussion of electricity and modern applications would be complete without some discussion of Thomas Alva Edison and his sentinel contributions. The first church, post office, and ship were illuminated in 1892. The first hotel, theater, and electric sign were in 1893. The rapidity of dispersal and secondary applications of Edison's inventions is typified by the rise of cystoscopes

  20. Thomas Hardy, Provincial Geology and the Material Imagination

    2008-04-01

    Full Text Available This essay explores the nineteenth-century traffic and exchange of fossils and natural-historical objects between province and metropolis as represented by two very different geological writers of the period, the fossil collector Gideon Mantell and the novelist Thomas Hardy. The men are connected through Mantell's 'The Wonders of Geology', the sixth edition of which (1848 Hardy read and utilised for his descriptions of the geological past in his third novel, 'A Pair of Blue Eyes' (1873. These two texts demonstrate a powerful investment in determining the meaning of the geological object according to the social and geographical spaces in which it is discovered, displayed, and discussed, so that the scientific object becomes the site around which complex cultural politics coalesce and sit in tension. In its consideration of the relationship between place and meaning in science, and in its focus on scientific material culture, this essay attempts to disrupt the current spotlight on the interrelationships between scientific law and narrative pattern in Victorian literary studies. Instead, it hopes to contribute to a discussion of the ways in which the novel's attention to scientific objects rather than narratives made it an important site of epistemological enquiry into the basis of scientific knowledge and the inseparability of that knowledge from the discourses and spaces which produced it.

  1. THEOLOGY AS CREATIVE LANGUAGE. THE CASE OF THOMAS BROOKS

    Ciprian SIMUȚ

    2015-12-01

    Full Text Available The problem of theological language has been a hindrance in coming closer to God, ever since complex patterns of thought have combined with the theological inquiry. The conclusion that helped Protestantism gain ground was bringing the theological message of the Bible to the understanding of every-day believer. An effort was made to explain how God works in history, and how to become more like Christ in one’s every-day life. However, mere copying was not the foundation of Christianity. Inner conviction born out of understanding the explanation from the Biblical message was crucial. Thomas Brooks was one of the protestant theologians who aimed to explain how the Devil and evil work against the believer, in order to create chaos, disorder, sorrow, hatred, deception, and ignorance. He did this by transforming the theological message into creative language, using every-day images in order to create a relation between theology and praxis. This paper will analyze some of the aspects found in Brooks’ theological presentation, in order to show how theology could be used for the benefit of the individual believer, as well as for the benefit of society.

  2. "The Leviathan" as automaton: method and politics in Thomas Hobbes

    Directory of Open Access Journals (Sweden)

    Diego Fernández Peychaux

    2014-02-01

    Full Text Available This article points out the tension between the normative purpose of Thomas Hobbes’s political texts, and the identification of the resolutive-compositive method of science as it is applied in those texts. In order to solve this difficulty one should appeal to Hobbes’s epistemological texts to read the example of the clock from a new perspective. Thus, if the Hobbesian method responds to the need for normative innovation, it not only denies an apologetic intentionality for a completely ignored historical reality, but also makes it possible to describe the relationship between the individual and the State in a manner different from traditional understandings. According to these conclusions, man ceases to be simply a mechanical part but rather becomes a cause, and therefore, a measure of the effectiveness and functionality of a State. Man’s savage individualism while in the state of nature is not the model, but the cause that justifies a Leviathan capable of turning the homo homini lupus into homo homini deus.

  3. A modified Thomas-Fermi treatment of nuclei

    1992-01-01

    An improved nuclear Thomas-Fermi theory is studied in which, rather than adding density-gradient corrections to the standard expression for the kinetic energy density (proportional to ρ 5/3 , where ρ is the density) one simply modifies this ρ 5/3 function to reflect the fact that the kinetic energy density becomes negative for small values of ρ when, in a typical nuclear problem, one is dealing with the outer fringes of the surface region. The net result of this study is simply stated: In order to find the density associated with a given nuclear potential, one exponentiates this potential instead of raising its depth with respect to the chemical potential to the three-halves power, as in the standard treatment. An improved description of the nuclear surface profile is obtained, including the quantal halo in the classically forbidden region. But since density derivatives are not involved, there is no need to solve a partial differential equation in order to find the density. (orig.)

  4. American Connections: The Early Works of Thomas Bang

    Ring Petersen, Anne

    2015-09-01

    Full Text Available The Danish artist Thomas Bang spent his early years in the USA. The works he created in this formative period were thus profoundly shaped by the contemporary movements in American art of the 1960s and 1970s when sculpture, or to be more precise, three-dimensional work became a hotbed of expansive experiments. This article traces how Bang made a radical move from painting to sculpture, which was characteristic of that time, and how he developed his artistic idiom by taking an active part in some of the seminal new departures in American art, in particular process art and post-minimalism. By leaping forward to Bang's later works produced after his return to Denmark, the article also demonstrates how the sculptural syntax and working principles developed in the early works still underlie and structure the artist's more allegorical sculptures and installations from the 2000s, thus testifying to the lasting impact of Bang's American period, which remains the key to understanding his works.

    I want to tell you about an improved Thomas-Fermi method for calculating shell-averaged nuclear properties, such as density distributions, binding energies, etc. A shell-averaged statistical theory is useful as the macroscopic component of microscopic-macroscopic theories of nuclei, such as the Strutinsky method, as well as in theories of nuclear matter in the bulk, relevant in astrophysical applications. In nuclear physics, as well as in atomic and molecular problems, the following question often has to be answered: you are given a potential well, say a deformed Woods-Saxon potential, into which you put N quantized fermions into the lowest N eigenstates, up to a ''Fermi energy'' To. You square the wave functions of the particles and add them up to get the total density ρ( r → ) = Σ i N |ψ i | 2 . Is there some simple way of estimating ρ( r → ) without going through the misery of numerically solving N partial differential Schroedinger equations for the N particles?

    Prophets provoke psychological unrest, especially when exposing accepted beliefs as profound deceptions. The biblical prophets exemplify such confrontation as do certain atheists ardently opposed to the images of God created by those seers. The German philosopher Friedrich Nietzsche dramatically illustrates this type of counterforce to the Judeo-Christian tradition. His prophet Zarathustra is intended to be a model for the modern mind, one free of superstitions inflicted by antiquated religious dogma. Nietzsche's credo "God is dead" served as a declaration for the nineteenth century. In the twentieth century, it became a theological diagnosis. As a "movement," or "tenor," the death of God or radical theology was spearheaded by Thomas Altizer, a well-published young professor center-staged during the turbulent 1960s. His work foreshadows a new strain of atheism currently represented by biologist Richard Dawkins (2006, The God delusion. New York: Houghton Mifflin), philosopher Daniel Dennett (2006, Breaking the spell. New York: Penquin), neuroscientist Sam Harris (2004, The end of faith. New York: W.W. Norton; 2008, Letter to a Christian nation. New York: Vintage), journalist Christopher Hitchens (2007, God is not great. New York: Twelve), and mathematician John Allen Paulos (Paulos 2008, Irreligion. New York: Hill & Wang). This twenty-first century crusade against belief in God is best understood as a psychodynamic ignited by Altizer's Christian atheism. The present dialogue reflects that dynamic while the prologue and epilogue reveal evidence of Providence amidst claims of God's demise in contemporary history.

    2008-10-01

    Introduction The South African health system has disturbing inequalities, namely few black doctors, a wide divide between urban and rural sectors, and also between private and public services. Most medical training programs in the country consider only applicants with higher-grade preparation in mathematics and physical science, while most secondary schools in black communities have limited capacity to teach these subjects and offer them at standard grade level. The Faculty of Health Sciences at Walter Sisulu University (WSU) was established in 1985 to help address these inequities and to produce physicians capable of providing quality health care in rural South African communities. Intervention Access to the physician training program was broadened by admitting students who obtained at least Grade C (60%) in mathematics and physical science at standard grade, and who demonstrated appropriate personal attributes. An innovative curriculum, combining problem-based learning with community-based education (PBL/CBE) in small tutorial group settings, was also adopted. This approach was aimed at educating and graduating a broader cohort of students, while training future doctors to identify, analyze, and treat health problems in the rural South African context. Outcomes To date, 745 doctors (72% black Africans) have graduated from the program, and 511 students (83% black Africans) are currently enrolled. After the PBL/CBE curriculum was adopted, the attrition rate for black students dropped from 23% to 80%, and the proportion of students graduating within the minimum period rose from 55% to >70%. Many graduates are still completing internships or post-graduate training, but preliminary research shows that 36% percent of graduates practice in small towns and rural settings. Further research is underway to evaluate the impact of their training on health services in rural Eastern Cape Province and elsewhere in South Africa. Conclusions The WSU program increased access to

    2012-12-01

    Full Text Available Abstract Background Jack bean urease (EC 3.5.1.5 is a metalloenzyme, which catalyzes the hydrolysis of urea to produce ammonia and carbon dioxide. The heavy metal ions are common inhibitors to control the rate of the enzymatic urea hydrolysis, which take the Hg2+ as the representative. Hg2+ affects the enzyme activity causing loss of the biological function of the enzyme, which threatens the survival of many microorganism and plants. However, inhibitory kinetics of urease by the low concentration Hg2+ has not been explored fully. In this study, the inhibitory effect of the low concentration Hg2+ on jack bean urease was investigated in order to elucidate the mechanism of Hg2+ inhibition. Results According to the kinetic parameters for the enzyme obtained from Lineweaver–Burk plot, it is shown that the Km is equal to 4.6±0.3 mM and Vm is equal to 29.8±1.7 μmol NH3/min mg. The results show that the inhibition of jack bean urease by Hg2+ at low concentration is a reversible reaction. Equilibrium constants have been determined for Hg2+ binding with the enzyme or the enzyme-substrate complexes (Ki =0.012 μM. The results show that the Hg2+ is a noncompetitive inhibitor. In addition, the kinetics of enzyme inhibition by the low concentration Hg2+ has been studied using the kinetic method of the substrate reaction. The results suggest that the enzyme first reversibly and quickly binds Hg2+ and then undergoes a slow reversible course to inactivation. Furthermore, the rate constant of the forward reactions (k+0 is much larger than the rate constant of the reverse reactions (k-0. By combining with the fact that the enzyme activity is almost completely lost at high concentration, the enzyme is completely inactivated when the Hg2+ concentration is high enough. Conclusions These results suggest that Hg2+ has great impacts on the urease activity and the established inhibition kinetics model is suitable.

    A five-year experimental study was conducted to evaluate the response of an upland jack-pine (Pinus banksiana) forest to elevated levels of nitrogen (N) deposition in Northern Alberta. N deposition in the region is expected to increase with industrial expansion of oil sands activity, and there is regional interest to set N critical loads for sensitive ecosystems. In this study, N was applied as NH4NO3 above a jack-pine canopy via helicopter, annually for five years (2010-2015) at dosages equivalent to 5, 10, 15, 20 and 25 kg N ha-1 yr-1. Approximately 35% of the applied N was retained in the canopy while 65% reached understory vegetation dominated by lichens and mosses. We measured a significant increase in tissue N concentrations of common ground lichens (Cladonia mitis and C. stellaris) and ground moss (Pleurozium schreberi) as well as epiphytic lichens (Hypogymnia physodes and Evernia mesomorpha). On an annual basis, the applied N was primarily captured in the lichen and moss understory, dominated by C. mitis. In the highest treatments, N concentrations in C. mitis were 1.5-2.5 times greater than pre-treatment values. Peak N concentrations in the ground moss Pleurozium schreberi (1.4%) indicate that a threshold of N saturation was reached by year 3. We observed no changes in community composition of vascular and non-vascular plants, or changes in vascular plant tissue N. Chlorophyll levels in C. mitis increased with N treatment, but there was no indication of toxicity or changes to decomposition and growth. After five years of N application, only Peltigera polydactylon, a ground cyanolichen, appeared to be negatively impacted where the thalli showed necrosis at deposition loads >10kg N ha-1 yr-1. No changes to biomass or N ecosystem processes were observed. Based on these observations, we provide evidence that the first adverse ecological effects of N deposition in jack-pine stands occurred at deposition rates of 10 kg N ha-1 yr-1.

    Understanding the physical and genetic structure of hybrid zones can illuminate factors affecting their formation and stability. In north-central Alberta, lodgepole pine (Pinus contorta Dougl. ex Loud. var. latifolia) and jack pine (Pinus banksiana Lamb) form a complex and poorly defined hybrid zone. Better knowledge of this zone is relevant, given the recent host expansion of mountain pine beetle into jack pine. We characterized the zone by genotyping 1998 lodgepole, jack pine, and hybrids from British Columbia, Alberta, Saskatchewan, Ontario, and Minnesota at 11 microsatellites. Using Bayesian algorithms, we calculated genetic ancestry and used this to model the relationship between species occurrence and environment. In addition, we analyzed the ancestry of hybrids to calculate the genetic contribution of lodgepole and jack pine. Finally, we measured the amount of gene flow between the pure species. We found the distribution of the pine classes is explained by environmental variables, and these distributions differ from classic distribution maps. Hybrid ancestry was biased toward lodgepole pine; however, gene flow between the two species was equal. The results of this study suggest that the hybrid zone is complex and influenced by environmental constraints. As a result of this analysis, range limits should be redefined.

    Full Text Available Background. The injured anterior cruciate ligament (ACL has a limited healing capacity leading to persisting instability. Hypothesis/Purpose. To study if the application of a brace, producing a dynamic posterior drawer force, after acute ACL injury reduces initial instability. Study Design. Cohort study. Methods. Patients treated with the ACL-Jack brace were compared to controls treated with primary ACL reconstruction und controls treated nonsurgically with functional rehabilitation. Measurements included anterior laxity (Rolimeter, clinical scores (Lysholm, Tegner, and IKDC, and MRI evaluation. Patients were followed up to 24 months. Results. Patients treated with the ACL-Jack brace showed a significant improvement of anterior knee laxity comparable to patients treated with ACL reconstruction, whereas laxity persisted after nonsurgical functional rehabilitation. The failure risk (secondary reconstruction necessary of the ACL-Jack group was however 21% (18 of 86 within 24 months. Clinical scores were similar in all treatment groups. Conclusion. Treatment of acute ACL tears with the ACL-Jack brace leads to improved anterior knee laxity compared to nonsurgical treatment with functional rehabilitation.

    Luis Ignacio García García

    2014-03-01

    This paper analyzes the reception of Walter Benjamin by the young Ricardo Piglia. Walter Benjamin, together with Bertolt Brecht, was very important for Piglia’s self-comprehension in the context of the agitated aesthetical-political debates of the ’60s and ’70s. Piglia makes use of the Brechtian Benjamin to articulate aesthetics and politics in a way that singles out his critical work in those years. He builds, from the parameters of a production aesthetic, a position that goes beyond not only the idealistic aesthetics but also the principles of the socialist realism, putting aside the opposition between aesthetic experimentation and politicization of art.

    The general one-dimensional open-quotes log-sineclose quotes gas is defined by restricting the positive and negative charges of a two-dimensional Coulomb gas to live on a circle. Depending on charge constraints, this problem is equivalent to different boundary field theories. We study the electrically neutral case, which is equivalent to a two-dimensional free boson with an impurity cosine potential. We use two different methods: a perturbative one based on Jack symmetric functions, and a non-perturbative one based on the thermodynamic Bethe ansatz and functional relations. The first method allows us to find an explicit series expression for all coefficients in the virial expansion of the free energy and the experimentally measurable conductance. Some results for correlation functions are also presented. The second method gives an expression for the full free energy, which yields a surprising fluctuation-dissipation relation between the conductance and the free energy

    Robishaw Engineering Inc., Houston, has designed and built a jack-up platform based on a modular flotation and erection system that allows exploratory and development drilling year round in any location that cannot be reached by conventional equipment. All components are light enough to be transported by helicopters rated for 4000-lb loads, yet strong and buoyant enough to serve as working platforms. The pile-supported self-elevating drilling platform consists of H-shaped steel girders joined by pin connectors and tension wires. Deck panels are steel-plated. When elevated on steel pilings, the platform can support loads imposed by rigs capable of drilling to 18,000 ft. One such unit is currently being used in the Peruvian rain forest.

    2018-01-01

    In this study, the phylogenetic trees of jacks and pompanos (Carangidae), an ecologically and morphologically diverse, globally distributed fish family, are inferred from a complete, concatenated data set of two mitochondrial (cytochrome c oxidase I, cytochrome b) loci and one nuclear (myosin heavy chain 6) locus. Maximum likelihood and Bayesian inferences are largely congruent and show a clear separation of Carangidae into the four subfamilies: Scomberoidinae, Trachinotinae, Naucratinae and Caranginae. The inclusion of the carangid sister lineages Coryphaenidae (dolphinfishes) and Rachycentridae (cobia), however, render Carangidae paraphyletic. The phylogenetic trees also show with high statistical support that the monotypic vadigo Campogramma glaycos is the sister to all other species within the Naucratinae. © 2017 The Fisheries Society of the British Isles.

    1992-12-01

    Gastrodia elata Bl. (GE) and Uncaria rhynchophylla (Miq.) Jacks (UR) are two traditional Chinese medicinal herbal drugs, used for the treatment of convulsions and epilepsy. Their antioxidant effects in vivo and their free radical scavenging effects in vitro were investigated. Epileptogenic foci in the lateral brain of the rat were induced by the injection of ferric chloride into the lateral cortex. Both extracts significantly inhibited the increase in levels of lipid peroxide in the ipsilateral cortex, at all times observed. In addition, the two extracts also induced an early increase of activity of superoxide dismutase in the mitochondrial fraction of the ipsilateral cortex. In in vitro experiments, the two extracts exhibited significant dose-dependent scavenging effects on free radicals, using electron spin resonance spectroscopy. These results suggest that the proposed antiepileptic effects of GE and UR may be attributable to the antioxidant activity of the active components in these two medicinal herbs.

    2010-10-01

    Eurycoma longifolia Jack is an herbal medicinal plant of South-East Asian origin, popularly recognized as 'Tongkat Ali.' The plant parts have been traditionally used for its antimalarial, aphrodisiac, anti-diabetic, antimicrobial and anti-pyretic activities, which have also been proved scientifically. The plant parts are rich in various bioactive compounds (like eurycomaoside, eurycolactone, eurycomalactone, eurycomanone, and pasakbumin-B) among which the alkaloids and quassinoids form a major portion. Even though toxicity and safety evaluation studies have been pursued, still a major gap exists in providing scientific base for commercial utilization and clearance of the Tongkat Ali products with regard to consumer's safety. The present review aims at reviewing the research works undertaken till date, on this plant in order to provide sufficient baseline information for future works and for commercial exploitation.

    1999-01-01

    With the syndrome of malignant narcissism, which is characterised by narcissistic personality disorder, anti-social behaviour, sadism and a marked tendency to paranoid reactions, Kernberg (1985, 1996) describes an independent form of pathological narcissism. According to Stone (1996) this is found in many mass-murderers and serial killers. On the basis of the example of Jack Unterweger the connection between malignant narcissism and sexual offence is discussed as to psychodynamic development, personality structure and psychopathology. Unterweger, who was convicted to lifelong imprisonment in 1976 for sadistic sexual murder, became a wellknown writer in prison and was released prematurely in 1990 as the Austria case of successful rehabilitation. As stated in the sentence passed against him he killed 11 prostitutes in Europe and the USA within the next 18 months, but never pleaded guilty. Psychiatric examination revealed numerous elements of malignant narcissism and the constellation of his development and life was typical of serial offenders.

    The jack jumper ant (Myrmecia pilosula) is responsible for greater than 90% of Australian ant venom allergy. However, deaths have only been recorded in the island of Tasmania. We sought to determine the prevalence, clinical features, natural history, and predictors of severity of M pilosula sting allergy in Tasmania. We performed a random telephone survey supported by serum venom-specific IgE analysis, review of emergency department presentations, and follow-up of allergic volunteers. M pilosula, honeybee (Apis mellifera), and yellow jacket wasp (Vespula germanica) sting allergy prevalences were 2.7%, 1.4%, and 0.6% compared with annual sting exposure rates of 12%, 7%, and 2%, respectively. Similarly, emergency department presentations with anaphylaxis to M pilosula were double those for honeybee. M pilosula allergy prevalence increased with age of 35 years or greater (odds ratio [OR], 2.4) and bee sting allergy (OR, 16.9). Patients 35 years of age or older had a greater risk of hypotensive reactions (OR, 2.9). Mueller reaction grades correlated well with adrenaline use. During follow-up, 79 (70%) of 113 jack jumper stings caused anaphylaxis. Prior worst reaction severity predicted the likelihood and severity of follow-up reactions; only 3 subjects had more severe reactions. Venom-specific IgE levels and other clinical features, including comorbidities, were not predictive of severity. Sting allergy prevalence is determined by age and exposure rate. M pilosula sting exposure in Tasmania is excessive compared with that found in mainland Australia, and there is a high systemic reaction risk in allergic people on re-sting. Prior worst reaction severity (Mueller grade) and age predict reaction severity and might be used to guide management.

    Baicalin (BA) is the principal component of Radix Scutellariae responsible for its pharmacological activity. In this study, kinetics and mechanism of inhibition by BA against jack-bean urease were investigated for its therapeutic potential. It was revealed that the IC50 of BA against jack-bean urease was 2.74 ± 0.51 mM, which was proved to be a competitive and concentration-dependent inhibition with slow-binding progress curves. The rapid formation of initial BA-urease complex with an inhibition constant of K i = 3.89 × 10−3 mM was followed by a slow isomerization into the final complex with an overall inhibition constant of K i* = 1.47 × 10−4 mM. High effectiveness of thiol protectors against BA inhibition indicated that the strategic role of the active-site sulfhydryl group of the urease was involved in the blocking process. Moreover, the inhibition of BA was proved to be reversible due to the fact that urease could be reactivated by dithiothreitol but not reactant dilution. Molecular docking assay suggested that BA made contacts with the important activating sulfhydryl group Cys-592 residues and restricted the mobility of the active-site flap. Taken together, it could be deduced that BA was a competitive inhibitor targeting thiol groups of urease in a slow-binding manner both reversibly and concentration-dependently, serving as a promising urease inhibitor for treatments on urease-related diseases.

    Tight hamstrings are reported to be one of the causes of low back pain. However, there have been few reports on effective stretching procedures for the tight hamstrings. The so-called jack-knife stretch, an active-static type of stretching, can efficiently increase the flexibility of tight hamstrings. To evaluate hamstring tightness before and after the 4-week stretching protocol in healthy volunteer adults and patients aged under 18 years with low back pain. For understanding the hamstrings tightness, we measured two parameters including (1) finger to floor distance (FFD) and (2) pelvis forward inclination angle (PFIA). Eight healthy adult volunteers who had no lumbar or hip problems participated in this study (mean age: 26.8 years). All lacked flexibility and their FFD were positive before the experiment. Subjects performed 2 sets of the jack-knife stretch every day for 4 weeks. One set consisted of 5 repetitions, each held for 5 s. Before and during the 4-week experiment, the FFD and PFIA of toe-touching tests were measured weekly. For 17 of the sports players aged under 18, only FFD was measured. In adult volunteers, FFD was 14.1 ± 6.1 cm before the experiment and decreased to -8.1 ± 3.7 cm by the end of week 4, indicating a gain in flexibility of 22.2 cm. PFIA was 50.6 ± 8.2 before the experiment and 83.8 ± 5.8 degrees after. Before and after the experiment, the differences were significant (p hamstrings.

    Full Text Available This paper analyses information on various macro environmental variables available since 1876 for the Southeast Pacific and more recent data on Jack mackerel Trachurus murphyi (Nichols, 1920 landings and biomass in the Peruvian sea, relating them to probable areas of water masses equivalent to Cold Coastal Waters (CCW and Subtropical Surface Waters (SSW. It is concluded that the index of the Pacific Decadal Oscillation (PDO presents expressions of variability that are consistent with those found for the Southern Oscillation Index (SOI and that the detected changes in biomass of Jack mackerel T. murphyiin the Peruvian sea reflect changes in the availability of the fish stock associated with secular (SOI and decadal (PDO variability patterns. These fluctuations in stock availability impact fisheries in Ecuador, Peru and northern Chile, which show significant variations in their landings and would have given a biased picture of the state of abundance, leading to wrong diagnoses of the real situation of the exploited stocks. These patterns of variability would also affect the appearance of El Niño, making them start in the southern hemisphere autumn or spring depending on whether the current PDO is positive or negative. Periods of high (1876 – 1925 and 1976 – 2012 and low (1926 – 1975 variability are also identified in relation to the Euclidean distance of the variances of the SOI; and in relation to the PDO a distinction is made between warm (1925 – 1944 and 1975 – 1994, cold (1945 – 1974 and tempered or interface periods (1895 – 1924 and 1995 – 2012, the latter being explained by the interaction between periods of high variability.

  6. Survey of foliar monoterpenes across the range of jack pine reveal three widespread chemotypes: implications to host expansion of invasive mountain pine beetle

    Full Text Available The secondary compounds of pines (Pinus can strongly affect the physiology, ecology and behaviors of the bark beetles (Coleoptera: Curculionidae, Scolytinae that feed on sub-cortical tissues of hosts. Jack pine (Pinus banksiana has a wide natural distribution range in North America (Canada and USA and thus variations in its secondary compounds, particularly monoterpenes, could affect the host expansion of invasive mountain pine beetle (Dendroctonus ponderosae, which has recently expanded its range into the novel jack pine boreal forest. We investigated monoterpene composition of 601 jack pine trees from natural and provenance forest stands representing 63 populations from Alberta to the Atlantic coast. Throughout its range, jack pine exhibited three chemotypes characterized by high proportions of α-pinene, β-pinene, or limonene. The frequency with which the α-pinene and β-pinene chemotypes occurred at individual sites was correlated to climatic variables, such as continentality and mean annual precipitation, as were the individual α-pinene and β-pinene concentrations. However, other monoterpenes were generally not correlated to climatic variables or geographic distribution. Finally, while the enantiomeric ratios of β-pinene and limonene remained constant across jack pine’s distribution, (‒:(+-α-pinene exhibited two separate trends, thereby delineating two α-pinene phenotypes, both of which occurred across jack pine’s range. These significant variations in jack pine monoterpene composition may have cascading effects on the continued eastward spread and success of D. ponderosae in the Canadian boreal forest.

    To assess the usefulness of percutaneous treatment of abnormalities of the venous tree in extending the survival of external Thomas shunts (TS). Twelve cases of TS were included in a hemodialysis access fistula dysfunction monitoring program and were followed for up to 48 months. The abnormalities found were treated by percutaneous transluminal angioplasty (PTA) or thrombolysis and PTA. Survival curves and the Kaplan-Meier method were used to calculate the likelihood of primary patency (P1), secondary patency (P2), and overall patency (OP). A total of 61 interventions were performed during the period of follow-up. On 12 occasions the fistula was thrombosed; in the rest, increased venous pressure to 150 mmHg or higher was detected during dialysis. Fistulography was performed after washing the thrombosed fistulas with urokinase, and revealed one or more of the following angiographic signs: 1) a short reduction of more than 50% in lumen caliber in the femoral vein adjacent to the anastomosis, present in 52% of the cases (fig. 1); 2) imaging a "jet" of contrast material at the site of entry of the shunt into the femoral vein (fig. 2), present in 22% of the cases; and 3) a filling defect or "flap" at the same site, owing to hyperplastic tissue or piece of thrombus adhering to the intima, present in 34% of the cases (figs. 3-5). This last-mentioned finding ordinarily gave rise to a "valve" effect, whereby injection into the venous branch was feasible but aspiration from the venous branch was difficult or impossible. PTA was carried out and attained anatomical and functional success in 100% of cases.

    Full Text Available Stupisce molto che un libro come Komposition im 20. Jahrhundert. Details - Zusammenhänge [Composizione nel 20° secolo. Particolari – Connessioni] di Walter Gieseler, pubblicato in Germania quasi venticinque anni fa, non abbia mai ricevuto un'attenzione maggiore. Strano destino, per un libro così ricco e innovativo, scritto da un autore cui andrebbe per lo meno tributato il merito di essere stato uno dei primi a realizzare una descrizione sistematica delle tecniche compositive novecentesche. Le ragioni vanno forse cercate nel fatto di non avere mai beneficiato di traduzioni in una lingua più ‘internazionale’ e di non appartenere, in senso convenzionale, né al settore propriamente analitico, né teorico-compositivo, né storico-musicale. Di fatto, il libro riassume tutti questi aspetti, nonché argomenti di materia estetica, esecutiva, psicologico-percettiva, notazionale, ecc.

  13. The two sides of the commodity. For an archeology of critical theory of consumption in the work of Walter Benjamin

    Directory of Open Access Journals (Sweden)

    2017-03-01

    Full Text Available The aim of this work is to trace a journey through the work of Walter Benjamin to give account of the existence of an incipient critical theory of consumption that appears, dispersed and fragmented among their major concerns as the status of the work of art, industrial technology or modern city. The idea that we intend to show is that the originality of Benjamin's proposal lies in the indirect nature by which access to the cultural question. Not so much as an instance derived from the production process determinations but from the transformations in the sphere of consumption. So the Arcades-Project can be read as a historic attempt to develop the contradiction of the commodity form that the consumer experience is presented as the cynical and utopian moment.

    Llewellyn Hilleth Thomas was born in 1903 and died in 1992 at the age of 88. His name is known by most for only two things, Thomas precession and the Thomas-Fermi atom. The many other facets of his career - astrophysics, atomic and molecular physics, nonlinear problems, accelerator physics, magnetohydrodynamics, computer design principles and software and hardware - are largely unknown or forgotten. I review his whole career - his early schooling, his time at Cambridge, then Copenhagen in 1925-26, and back to Cambridge, his move to the US as an assistant professor at Ohio State University in 1929, his wartime years at the Ballistic Research Laboratory, Aberdeen Proving Grounds, then in 1946 his new career as a unique resource at IBM's Watson Scientific Computing Laboratory and Columbia University until his first retirement in 1968, and his twilight years at North Carolina State University. Although the Thomas precession and the Thomas-Fermi atom may be the jewels in his crown, his many other accomplishments add to our appreciation of this consummate applied mathematician and physicist. )

    There are many cardioplegia solutions currently in use for pediatric cardiopulmonary bypass (CPB). The most common being del Nido solution. Another common cardioplegia solution used for pediatric CPB is St. Thomas. In October 2014, Children's Mercy Kansas City changed from the use of modified St. Thomas to del Nido. This study compared rates of post cross-clamp fibrillation requiring defibrillation between del Nido solution and modified St. Thomas solution stratified by weight at Children's Mercy Kansas City. This retrospective study consisted of 394 patients who underwent cardiac surgery requiring cardioplegia between January 1, 2014 and July 31, 2015. The outcome measured was defibrillation upon cross-clamp removal. Statistical significance was determined using Fishers exact test with a two-sided significance level of .05. Incidence of defibrillation post cross-clamp removal was 4.4% in the del Nido group and 26.8% in the St. Thomas group (p Thomas group (p Thomas group (p Thomas group (p 60-kg category had an incidence of defibrillation of 16.7% in the del Nido group and 63% in the St. Thomas group (p Thomas and del Nido cardioplegia solutions. Analyses of weight stratifications demonstrate a decrease in the rate of defibrillation post cross-clamp removal in all categories within the del Nido group.

    Full Text Available Dryers heated by solar energy have been constructed and used in drying whole and half jack fruit almonds. The samples were dried during the day in direct sun and in the conventional solar dryer prepared for this purpose. Another piece of equipment was built for reception and accumulation of sun energy in a body of water, which was used as a heat source for night drying. The drying with the sun energy was compared with artificial drying. The jack fruit almonds were dried whole, half, with pellicle and without it. The storage of solar energy in water was technically viable for use in night drying. The drying by combining solar dryers in the day and night periods were completed in approximately 35 hours, and were equivalent to artificial drying between 40ºC and 70ºC. Almond cut in half and the pellicle removed reduced the drying time.Secadores com aquecimento por energia solar foram construídos e utilizados em secagens de amêndoas de jaca inteiras e em metades. As secagens no período diurno foram realizadas por exposição direta ao sol e em secador solar convencional, elaborado para este fim. Construiu-se também um equipamento para captação e acumulação de energia solar em uma massa de água, a qual foi utilizada como fonte de calor para realização de secagens no período noturno. As secagens com o uso de energia solar foram comparadas com secagens artificiais. As amêndoas de jaca foram secadas inteiras, em metades, com e sem película. O armazenamento da energia solar em corpo de água mostrou-se viável do ponto de vista técnico para utilização em secagens noturnas. As secagens combinando secadores por energia solar nos períodos diurno e noturno foram concluídas em tempos aproximados de 35 horas e equivaleram a secagens artificiais entre 40 ºC e 70 ºC. O corte das amêndoas e a retirada das películas reduziram o tempo de secagem.

  17. A Change in Igneous Activity of the Jack Hills Zircon Sources ca. 3.9 Ga

    New Ti-in-zircon crystallization temperature (Txlln) data for Jack Hills zircons reveal that the tight clustering of Hadean grains around a Txlln of 680°C, possibly indicative of felsic-to-intermediate minimum melting conditions, continues to ~3.92 Ga. Between 3.92-3.82 Ga the 680°C clustering ceases and most concordant grains cluster around an apparent Txlln of 610°C. A small group of zircons with higher Txlln (~750°C), present during the Hadean, is also observed during this period. After 3.82 Ga a Hadean-like distribution resumes for ~100 Ma. This large, concordant, low-Ti group at ~3.9 Ga is statistically distinct from the Hadean distribution and appears to be unique in the Jack Hills zircon record. The existence of coeval high- and low-Ti groups suggests that two distinct zircon-forming processes are distinguishable ~3.9 Ga, unlike during the Hadean. The significant numbers of zircons with apparent Txlln below 600°C may be suggestive of subsolidus formation, since igneous units with solidii below 600°C are relatively rare. The higher-Ti group is more consistent with an intermediate to mafic igneous origin but metamorphic overprinting or subsolidus formation at granulite grade cannot be ruled out by Txlln alone. A substantial proportion of the high-Ti group display oscillatory and disrupted oscillatory zoning in cathodoluminescence images, usually indicative of igneous origins and later metamorphism, respectively; most low-Ti grains are homogeneous. Several of each group display patchy zonation indicative of metamorphic overprinting. Although several grains with apparent Txlln >600°C display oscillatory zonation, the majority of the low-Ti group do not show textural evidence for igneous origins. We interpret these results to indicate the transition from a mechanism(s) that produced dominantly 680°C apparent zircon temperatures at ca. 3.9 Ga to include a new zircon-forming process in the sediment source(s), likely a protracted period of metamorphism

    User-generated smartphone applications have created a new level of virtual connectivity for gay males, one in which users can create profiles and meet other users as nearby or as far away as possible. For those within close proximity, the other users can be considered their "virtual neighbors." Although the applications are theoretically designed to be places of inclusion and not exclusion, where any gay male with economic means can download an application, many profiles have been created that exclude other users. Through an examination of profiles on one such application, Jack'd, exclusion is found in the way users celebrate and reinforce ideas of traditional masculinity and denigrate and reinforce stereotypic ideas of femininity embodied by some gay men. Jack'd, and other user-generated smartphone applications, can be read as virtual neighborhoods where one is excluded based on their gender performance.

    Dr. Thomas Charles Van Flandern, an expert in celestial mechanics and cosmology, died January 9, 2009 in Seattle, Washington, of colon cancer. He was 68. Van Flandern was an astronomer at the U.S. Naval Observatory from 1963 to 1983. He developed software to predict and analyze lunar occultations to improve lunar orbital and fundamental star catalog data. In later years he championed increasingly controversial theories. But his 1978 prediction that some asteroids have natural satellites, which was almost universally rejected, was verified when the Galileo spacecraft photographed Dactyl, a satellite of (243) Ida, during its flyby in 1993. Besides astronomy and computers, he had strong interests in biochemistry and nutrition, and he ran a business selling personal computers in the 1980s. Tom Van Flandern was born June 26, 1940 in Cleveland, Ohio, the first child of Robert F. Van Flandern and Anna Mary Haley. His father, a police officer, left the family when Tom Van Flandern was 5. His mother died when he was 16; he and his siblings then lived with their grandmother, Margery Jobe, until he went to college. Tom Van Flandern became interested in astronomy as a child. He used his first telescope, purchased with newspaper delivery earnings, to observe lunar occultations, and then learned how to predict them, sparking a life-long passion for dynamical astronomy. While attending St. Ignatius High School, Van Flandern and fellow student Thomas Petrie organized the Cleveland Moonwatch team to observe the first artificial satellites, the only team without an adult organizer. In 1958, Tom Van Flandern entered Xavier University where he led the Cincinnati Moonwatch team. He learned computer programming at a summer job with General Electric and wrote software to calculate "look angles" from orbital elements. The Cincinnati team became a top producer of observations using these predictions. Tom obtained a B.S. in mathematics from Xavier in 1962. He spent the next year at

  20. A relativistic extended Fermi-Thomas-like equation for a self-gravitating system of fermions

    The authors extend previous results of a Fermi-Thomas model, describing self-gravitating fermions in their ground state, to a relativistic gravitational theory in Minkowski space. In such a theory the source term of the gravitational potential depends both on the pressure and the density of the fluid. It is shown that, in correspondence of this relativistic treatment, still a Fermi-Thomas-like equation can be derived for the self-gravitating system, though the non-linearities are much more complex. No Fermi-Thomas-like equation can be obtained in the General Relativistic treatment. The canonical results for neutron stars and white dwarfs are recovered and also some erroneous statements in the scientific literature are corrected
