  2. Dynamics of human-divine civilization with an overview of Bernard Lewis' standpoints

    Directory of Open Access Journals (Sweden)

    Hadžajlić Mirsad

    2014-01-01

    Full Text Available An unbiased scientific research evaluating our until recently leading civilization, the Islamic civilization, based on the research of a famous researcher in the area of Islamic world, Bernard Lewis, shows its collapse both in the field of military and economic power and in the fields of culture and science. It seems that the Islamic civilization, with its inherent discrimination between the three categories of humans: Muslim - non-Muslim, slave - master, woman - man, has been by far superseded with contemporary theories about free and civil society, human rights, tolerance and the like. Philosophically discussing human being as such, this work comes up with the definition of human being which is naturally acceptable, both from the purely rational and intuitive point of view, as well as from the viewpoint of traditional theses about human being. Both of these cognitive resources show that it is natural for the human, as a divine being - which can be under influence of Satan or even be a satanic being - to reside in a kind of mythological world. Since contemporary scientific standards reject the mythological as non-scientific, howsoever precise and objective analyses it offers, it is not possible to apply these standards, as such, on humanistic, particularly religious sciences. According to the mythological description of the world, though God himself gave Satan the ability to act against the humans, but before that He gave to the humans the ability to show and prove their own superiority. In this sense, Islamic civilization emerges as the civilization of the Human-centric divinity and the Theo-centric humanity; if there is any discrimination, it is only to improve that divine humanity and to protect it from satanic anti-human plots and pretensions. Hence, the Islamic human-loving civilization, with more or less intensity, has existed and exists in each corner of the history and the world where there is care, theories and actions to preserve and

  5. Bernard Hyams (1925 - 2015)

    CERN Multimedia

    2015-01-01

    Bernard Hyams, a distinguished scientist who worked at CERN for 32 years, died on 15 May 2015 at the age of 90.     He started his career in Manchester, at Blackett’s laboratory, working on a magnetic spectrograph to measure the momentum of single cosmic ray particles (1950). Then, leading a group from Manchester University, he set up a cosmic ray experiment at the Pic du Midi Observatory in France. Having joined CERN in 1958, he performed one of the first experiments at the PS by demonstrating that in pion decay the muon spin behaves as expected. After studying vector meson decays into muon pairs, he spent several years working on precision pion measurements. When the ISR started operation in early 1971, it was realised that there was no experiment in place capable of looking for quarks, which was quite sobering, considering the ISR was constructed as a “discovery machine”. Bernard acted decisively, supporting a small and mostly young team of...

    Science.gov (United States)

    Donnet, V

    1998-01-01

    During his stay at Villefranche-sur-Saône College, Claude Bernard became acquainted with Ferdinand Donnet, appointed a short while ago, priest of the Parish. This priest became Cardinal and carried out his apostolate at Bordeaux for 47 years. 40 years after their meeting at Villefranche, Cardinal Donnet and Claude Bernard found again each other as "Sénateurs d'Empire" in Paris. In his writings, Claude Bernard never mentioned Religion: he rather gave impression, in many ways, of being anticlerical! Paul Bert and his colleagues looked upon Claude Bernard as a great priest of atheism. Shortly after his death, Cardinal Donnet wrote a letter where he entirely proved that Claude Bernard has been, on the contrary, a fervent catholic.

  8. Bernard Tschumi Draws Architecture!

    Directory of Open Access Journals (Sweden)

    Gevork Hartoonian

    2014-08-01

    Full Text Available Bernard Tschumi’s delineation prepared for the Museu de Arte Contemporânea provides the starting point for this essay, which discusses the historicity of drawing and highlights the horizontality and the verticality that structure architecture’s contrast with the pictorial realm. Juxtaposing a freehand sketch with the digital image of the same project, Tschumi moves to address the paradox concerning the position of the body and drawing. This drawing also speaks for the reversal in the position of the body brought about by digital reproductivity.The reversal alludes to Tschumi’s theorization of architecture in terms of space and event. These, I will argue, are anticipated in The Manhattan Transcripts (1981 where a set of freehand drawings is used to evoke a filmic mood wherein the image is projected parallel to the spectator’s seated position. The essay goes further, suggesting that the theatricality permeating the present architecture is part of the shift from horizontality to the painterly, and yet the phenomenon is not merely a technical issue. Rather, it alludes to architecture’s dialogical rapport with painting at work since the Renaissance.

  4. The aesthetics of laboratory inscription: Claude Bernard's Cahier Rouge.

    Science.gov (United States)

    Sattar, Atia

    2013-03-01

    This essay explores the aesthetic sensibilities of the French physiologist Claude Bernard (1813-1878). In particular, it analyzes the Cahier Rouge (1850-1860), Bernard's acclaimed laboratory notebook. In this notebook, Bernard articulates the range of his experience as an experimental physiologist, juxtaposing without differentiation details of laboratory procedure and more personal queries, doubts, and reflections on experimentation, life, and art. Bernard's insights, it is argued, offer an aesthetic and phenomenological template for considering experimentation. His physiological point of view ranges from his own bodily aesthesis or sensory perception, through personal reflections on scientific discovery as an artistic process, to a broader metaphysical conception of life as an artistic creation. Such an aesthetic approach to physiology enables Bernard to reconcile his empirical methodology and his romantic idealism; it offers the history of laboratory science a framework for considering the individual, bodily, and emotional labor inherent in physiological experimentation.

    1981-01-01

    Fourteen osteosarcomas were observed among the eight St. Bernards that died following the injection of 239 Pu. Early data tentatively indicate that the St. Bernard is about 5 times more sensitive than the beagle and about 130 times more sensitive than the average person is estimated to be to 239 Pu-induced bone sarcomas. Thus the St. Bernard may be an excellent model in which to study the pathogenesis of bone cancer induction, to evaluate the relationship between spontaneous susceptibility and radiosensitivity, and to determine whether radiosensitivity significantly affects the toxicity ration of 239 Pu/ 226 Ra

    Thirteen osteosarcomas have been observed among the 7 St. Bernards that have died following the injection of 239 Pu. Preliminary data indicate that the St. Bernard is about 6 times more sensitive than the Beagle, and about 150 times more sensitive than the average person is to 239 Pu-induced bone sarcomas.

  8. Lewis Acidic Ionic Liquids.

    Brown, Lucy C; Hogg, James M; Swadźba-Kwaśny, Małgorzata

    2017-08-21

    Until very recently, the term Lewis acidic ionic liquids (ILs) was nearly synonymous with halometallate ILs, with a strong focus on chloroaluminate(III) systems. The first part of this review covers the historical context in which these were developed, speciation of a range of halometallate ionic liquids, attempts to quantify their Lewis acidity, and selected recent applications: in industrial alkylation processes, in supported systems (SILPs/SCILLs) and in inorganic synthesis. In the last decade, interesting alternatives to halometallate ILs have emerged, which can be divided into two sub-sections: (1) liquid coordination complexes (LCCs), still based on halometallate species, but less expensive and more diverse than halometallate ionic liquids, and (2) ILs with main-group Lewis acidic cations. The two following sections cover these new liquid Lewis acids, also highlighting speciation studies, Lewis acidity measurements, and applications.

    It happened as fast as the collapse of a mine shaft. In October, as the federal budget ax began swinging in earnest, the U.S. Department of the Interior did some cutting of its own, lopping off the 85-year-old federal Bureau of Mines. The bureau's 1,200 employees were to be laid off by January 16 (although that picture has been clouded by the federal shutdown), just 90 days after they were sacrificed to cost-cutting measures by Secretary of the Interior Bruce Babbitt, according to The Washington Post.

    Full Text Available In a response to our article “Political Ideology and Racial Preferences in Online Dating,” Kevin Lewis (2015 has raised concerns about various aspects of our analysis of user behavior on a national online dating site. The core of Lewis’ critique is that we do not report specifics of the sample, the website, and the analysis. Lewis also details numerous smaller points with respect to details of the analysis. The goal of this response is not to reply to every point that Lewis makes. As with any research project, our design decisions require tradeoffs, and readers should evaluate the evidence on their own. Rather, we use this space to make broader points about the general value for sociology of research using online data and how such research should be practiced.

    The author first reviews the services offered by the Bureau to the user community scattered over three separate physics departments and a theory research institute. Limited services are offered also to non- physics research in the University, in collaboration with the University Computing Center. The personnel is divided into operations sections responsible for the terminal and data archive management, punching and document services, etc. and into analysts sections with half a dozen full-time scientific programmers recruited among promising graduate level physics students, rather than computer scientists or mathematicians. Analysts are thus able not only to communicate with physicists but also to participate in research to some extent. Only more demanding program development tasks can be handled by the Bureau, most of the routine data processing is the users responsibility.

    Robbins, Chandler S.

    1993-01-01

    Arthur Bernard Singer was born 4 December 1917, and died 6 April 1990. Although brought up in New York City, Arthur developed an early fascination with birds. His favorite haunts were the Bronx Zoo and the American Museum of Natural History, where Robert Cushman Murphy encouraged his efforts and where Arthur acquired a worldwide perspective. After graduating from Cooper Union Art School in New York City in 1939, he began his career as an art teacher, art director, and designer, His real interest, however, was in depicting the postures and plumages of birds and mammals. As early as 1941 his wildlife art was exhibited at the Bronx Zoo. While he was in the army, his wife Edith (“Judy”) helped mount this first exhibit; Arthur never saw the show.

  8. Moral Luck from Bernard Williams’ Point of View

    Directory of Open Access Journals (Sweden)

    Zahra Khazai ; Fatemeh Tamaddon

    2016-08-01

    Full Text Available Moral luck is an important issue in meta- ethics. Its conflict to principle of control make challenges to moral moral assessment, moral judgment and moral responsibility. Bernard Williams is the first philosopher who uses the expression "moral luck" and tries to show that the contradiction between “moral” and “luck” is not so serious. Against Kantian’s idea and also our intuitions Williams doesn’t believe that morality is immune of luck and that unlike other values, is accessible to all people. If moral value is accessible to all, according to his idea, it should be not only immune of luck but also supreme. Giving some examples, Williams by concepts like justification, regret and retrospective, shows that morality hasn’t these characteristics. Dividing moral luck into four types: resultant, circumstantial, constitutive and causal, Thomas Nagel puts Williams' moral luck under the first type and criticizes it. This study seeks to explain Bernard Williams’ viewpoint on moral luck. At first it clears types of moral luck, principle of control and its contradiction with moral luck, then after explaining Williams’ account of moral luck criticizes it. Nagel’s criticisms and others show that although they accept the existence of moral luck and also their account is compatible to williams’ but they deny williams’ success in defending of this phenomenon.

    International Nuclear Information System (INIS)

    Gariel, J.; Marcilhacy, G.

    2001-03-01

    We obtain the general solution of the axisymmetric stationary vacuum spacetime of Lewis. After precising the fundamental hypothesis of Lewis, we demonstrate that the solution is related to an arbitrary harmonic function. Formally, these solutions are the same as for the corresponding cylindrically symmetric case, and can be classified in a similar way. Furthermore, the interpretation, in the cylindrically symmetric system, of the field equations as decribing the motion of a classical particle in a central force field is still valid. (author)

    Marck, K W; Martin, D

    2017-12-01

    The use of eponyms honours those who have contributed to the development of medicine and facilitates communication between colleagues. Eponyms are based on historical knowledge to know who was the first to use a given technique. In the previous century, two different operative procedures have been attached to the 'so called' Bernard lower lip reconstruction. This historical literature on lip reconstruction with a focus on the years 1853-1855 elucidates the roles of Bernard, Saeman, Desgranges and Burow, and gives suggestions for eponyms that do justice to the innovating surgeons Bernard, Burow and Desgranges.

  16. St. Bernard Parish : la crise d’un territoire suburbain St. Bernard Parish, the crisis of a suburban territory

    Directory of Open Access Journals (Sweden)

    Jean-Marc Zaninetti

    2009-04-01

    Full Text Available Situé à l’est de La Nouvelle-Orléans, St. Bernard Parish est l’un des territoires les plus vulnérables au risque d’ondes de tempêtes de toute la région métropolitaine. Après avoir été ravagée par le cyclone Katrina en 2005, St. Bernard peine à se redresser et montre le plus faible niveau de reprise de toute la région du Golfe du Mexique frappée par Katrina. De plus, la reconstruction est freinée par des polémiques virulentes qui nous rappellent les pires années des tensions raciales des années 1960. Cet article s’intéresse aux relations supposées entre les fragmentations urbaines et la faculté d’adaptation aux risques naturels. L’étude du cas de St. Bernard illustre la force d’inertie des territoires et comment de vieilles querelles ville-banlieue affaiblissent la résilience urbaine.Located east of New Orleans, St. Bernard Parish is one of the most vulnerable parts of the greater New Orleans metropolitan area to storm surges. After having been devastated by Hurricane Katrina in 2005, St. Bernard still struggles to recover from the storm, and displays the lowest recovery level of the entire Katrina-hit Gulf Coast area so far. Moreover, reconstruction is hampered by loud polemics that remind us of the worst years of racial polarization during the 1960’s. This paper explores the possible linkage between urban fragmentations and adaptive capacity to natural hazard. The St. Bernard case-study illustrates the strength of path dependency, and how long-entrenched suburb-central city mistrust hampers urban resilience.

  20. Value of credit bureau reports

    Directory of Open Access Journals (Sweden)

    Brković Milan

    2017-01-01

    Full Text Available An efficient system of credit information sharing contributes to solving the problem of information asymmetry on the credit and financial markets in general. The consequences of the global economic and financial crisis revealed an increasing demand for reliable information and data which could close the existing gap in their insufficiency, misuse or inadequate analytical value for the economic and financial policy makers. In that sense, more attention is directed to the usefulness of credit information sharing and the practical value of information and data contained in credit bureau reports for the purposes of achieving the overall economic policy goals. The fulfillment of that role depends mostly on the credit information sharing system and its characteristics, participants, and procedures. A credit bureau report in the best possible manner reflects all advantages and disadvantages of the established credit information exchange system in terms of its analytical value for the purposes of efficient macroeconomic and macrofinancial policies.

    Directory of Open Access Journals (Sweden)

    Marleide da Mota Gomes

    2014-04-01

    Full Text Available Claude Bernard (1813-1878 followed two main research paths: the chemical and physiological study of digestion and liver function, along with experimental section of nerves and studies on sympathetic nerves. Curare studies were, for example, of longstanding interest. His profound mental creativity and hand skillfulness, besides methodology quality, directed his experiments and findings, mainly at the Collège de France. His broader and epistemological concerns were carried out at the Sorbonne and later at the Muséum national d'Histoire naturelle. His insight gave clues to define the “ milieu intérieur”, later known as “homeostasis”, and grasp the brain complexity. Bernard followed and surpassed his master François Magendie who also fought against dogmas and laid the foundations of experimental medicine, and its main heinous tool – vivisection. Bernard created the methodological bases of experimental medicine, and collected honors as a renowned researcher.

  6. The two Bernard Berenson cousins: The interplay among immigration, culture, and narcissism.

    Science.gov (United States)

    Goldberg, Susan G

    2016-12-01

    The lives of two 19th century cousins, both of whom changed their names to Bernard Berenson, are considered from historical and psychodynamic perspectives, using a psychobiographical method. The Jewish cousins immigrated separately to Boston from Lithuania in 1875 and 1882. One cousin, later calling himself simply B.B., became a world-renowned art historian. The other Bernard became a misanthrope after feeling deeply humiliated by his cousin's family in Boston. Many biographies were written about the famous B.B. The only histories of his cousin Bernard were family stories, as he was the author's great-grandfather. The intersecting lives of these cousins are discussed. Both men faced the challenges of immigration as well as intense anti-Semitism and prejudice in each country in which they lived. These cultural and historical conditions interacted with the cousins' narcissistic vulnerabilities. Their lives demonstrate different manifestations of narcissistic suffering, with B.B's being more consistent with the construct of a "grandiose narcissist" and Bernard's being more consistent with that of a "closet narcissist." The life stories of these two cousins with the same name offers an intriguing instance of a complicated relationship among immigration, prejudice, and narcissism and case examples of the manifestation of how narcissistic suffering can influence lives.

  10. Quantification of Lewis acid induced Brønsted acidity of protogenic Lewis bases.

    Lathem, A Paige; Heiden, Zachariah M

    2017-05-09

    Proton transfer promoted by the coordination of protogenic Lewis bases to a Lewis acid is a critical step in catalytic transformations. Although the acidification of water upon coordination to a Lewis acid has been known for decades, no attempts have been made to correlate the Brønsted acidity of the coordinated water molecule with Lewis acid strength. To probe this effect, the pK a 's (estimated error of 1.3 pK a units) in acetonitrile of ten protogenic Lewis bases coordinated to seven Lewis acids containing Lewis acidities varying 70 kcal mol -1 , were computed. To quantify Lewis acid strength, the ability to transfer a hydride (hydride donor ability) from the respective main group hydride was used. Coordination of a Lewis acid to water increased the acidity of the bound water molecule between 20 and 50 pK a units. A linear correlation exhibiting a 2.6 pK a unit change of the Lewis acid-water adduct per ten kcal mol -1 change in hydride donor ability of the respective main group hydride was obtained. For the ten protogenic Lewis bases studied, the coordinated protogenic Lewis bases were acidified between 10 and 50 pK a units. On average, a ten kcal mol -1 change in hydride donor ability of the respective main group hydride resulted in about a 2.8 pK a unit change in the Brønsted acidity of the Lewis acid-Lewis base adducts. Since attempts to computationally investigate the pK a of main group dihydrogen complexes were unsuccessful, experimental determination of the first reported pK a of a main group dihydrogen complex is described. The pK a of H 2 -B(C 6 F 5 ) 3 was determined to be 5.8 ± 0.2 in acetonitrile.

  17. [Claude Bernard, the experimental method, and the Société de Biologie].

    Science.gov (United States)

    Bange, Christian

    2009-01-01

    Claude Bernard was one of the founder of the Société de Biologie created in 1849. He actively took part to it from its very beginning by presenting various communications and several important memoirs. Epistemological thoughts found in these memoirs lead to the methodological chapters introducing the volumes of his edited lessons given at the Collège de France. In 1865, these texts formed the basis to his Introduction à l'étude de la Médecine expérimentale, in which Bernard claims the experimental method should rely on the principle of determinism of the phenomena of Life. He was a dutiful President of the Société from 1867 until his death. He nevertheless was not often involved in debates, but agreed on the defense of the scientific principles he had claimed. He remained influential until his death, as noted in 1899 by the report Engène Gley wrote on the Société de Biologie during its fifty first years. Gley points regularly to Bernard's axioms which remained the true scientific credo of French biologists.

  18. The concept of the spiritual path in the views of Augustine and Bernard of Clairvaux: comparative analysis

    A. V. Timofeev

    2015-01-01

    Full Text Available The article examines the transformation of St. Augustine’s anthropological views in virtually unexplored in Ukraine philosophical and theological teachings of the medieval mystic Bernard of Clairvaux. Research field focused on the issues of negative and positive theological approaches, metaphysical and existential position of philosophical view of the problem of man. Based on the study of foreign scientists, outlines the key aspects of Augustinian doctrine of the human desire for God, the theoretical basis for philosophical and theological views of St. Bernard of Clairvaux. The conclusions substantiated regarding the impact of anthropological views of St. Augustine on the formation of existential components in the concept of the spiritual path of Bernard of Clairvaux. Transforming an ontological approach to the problem of man in practical sense of being in God as a form of spiritual path, St. Bernard complements the existential aspect of Christian anthropology. By means of a comparative analysis revealed the originality of the author’s approach St. Bernard to the problem of man’s spiritual development, which finds expression in the symbolic images of the spiritual marriage ­ an allegorical interpretation of the relationship between God and the soul at the highest levels of mystical contemplation. Dominant moral and practical sense in the teaching of St. Bernard is presented as a justification for the tendency to anthropological turning in medieval philosophy.

    Sibi, Mukund P; Soeta, Takahiro; Jasperse, Craig P

    2009-12-03

    Lewis acid complexation is generally required for chiral-auxiliary-controlled stereoselectivity, and chiral Lewis acid catalysis is frequently optimal for introducing asymmetry. In this work, we show that nitrile ylide cycloadditions to electron-poor acceptors attached to chiral auxiliaries proceed in high yield and stereoselectivity in the absence of Lewis acids. In contrast, chiral Lewis acids are inferior in these cycloadditions.

  2. Slovene critics on Sinclair Lewis's novels

    Directory of Open Access Journals (Sweden)

    Vanja Avsenak

    2010-12-01

    Full Text Available The purpose of this article is to present the reception of Sinclair Lewis's novels by Slovene critics. Initially, the article focuses on the life and workof Sinclair Lewis, giving special emphasis to social influences that made the author a representative figure in the literary and social world. Thus his works are nowadays to be understood primarily as fiction, but on the other hand also as sociological documents of a social and political situation of the period between the two world wars. Generally, the effect they produce is one of a critical discussion of the nation of the United States. When speaking of the social relevance that Lewis's novels have, it is obvious that his works are the portrayals of Americans and their deficiencies. At the time of their publication Lewis's novels received unfavourable criticism on accountof his overly open pro-European attitude and Slovene critics of the period before World War II emphasise this in much detail. It was precisely this anti-American propaganda in the novels themselves and sincerity on the part of the novelist that won the European critics as well as the readers whenit came to appreciating his works. However, Lewis's view of the Americans, as presented throughout his works, only enhanced his literary credibility as a modern writer. That is why the articles by Slovene critics that appeared after the Second World War, and even more significantly after Lewis's death, almost minutely reflect a more favourable attitude to Sinclair Lewis, which was also the case with foreign literary criticism of the post-war period. Critics still discuss the qualities and flaws of Lewis's novels, but being more lenient they no longer profess that the novels lack in artistic value. They remain, however, primarily relevant as social documents of the pre- and post-war era, which fully presented the American middle-class mentality in America and elsewhere. For this reason, the Nobel Prize for Literature awarded to

    Selosse, Marc-André; Minasiewicz, Julita; Boullard, Bernard

    2017-08-01

    We translate Noël Bernard's discovery of orchid symbiotic germination discovered on Neottia nidus-avis, as published in the May 1899 issue of the Comptes rendus hebdomadaires des séances de l'Académie des sciences. In his note, Bernard (1874-1911) establishes the need for a fungus, which is also forming mycorrhizae in adults, for seeds germination. We provide illustrations reproduced from his later works, and summaries of the French text he cited. In our annotations, we show how early this discovery was done in Bernard's career, and insist on the scientific framework at the end of the nineteenth century, where orchid germination was mysterious and the need for vicinity of parents was not fully understood. We comment the text of Bernard on the basis of the most recent knowledge on Neottia nidus-avis and on orchid mycorrhizal fungi. Introducing his following papers, we finally discuss the emergence of the concept of peloton digestion, and how Bernard's work quickly paved the way to a general understanding of mycoheterotrophic germination in orchids and beyond.

  11. Nonsense mutation in the glycoprotein Ibα coding sequence associated with Bernard-Soulier syndrome

    International Nuclear Information System (INIS)

    Ware, J.; Russell, S.R.; Vicente, V.; Scharf, R.E.; Tomer, A.; McMillian, R.; Ruggeri, Z.M.

    1990-01-01

    Three distinct gene products, the α and β chains of glycoprotein (GP) Ib and GP IX, constitute the platelet membrane GP Ib-IX complex, a receptor for von Willebrand factor and thrombin involved in platelet adhesion and aggregation. Defective function of the GP Ib-IX complex is the hallmark of a rare congenital bleeding disorder of still undefined pathogenesis, the Bernard-Soulier syndrome. The authors have analyzed the molecular basis of the disease in one patient in whom immunoblotting of solubilized platelets demonstrated absence of normal GP Ibα but presence of a smaller immunoreactive species. The truncated polypeptide was also present, along with normal protein, in platelets from the patient's mother and two of his four children. Genetic characterization identified a nucleotide transition changing the Trp-343 codon (TGG) to a nonsense codon (TGA). Such a mutation explains the origin of the smaller GP Ibα, which by lacking half of the sequence on the carboxyl-terminal side, including the transmembrane domain, cannot be properly inserted in the platelet membrane. Both normal and mutant codons were found in the patient, suggesting that he is a compound heterozygote with a still unidentified defect in the other GP Ibα allele. Nonsense mutation and truncated GP Ibα polypeptide were found to cosegregate in four individuals through three generations and were associated with either Bernard-Soulier syndrome or carrier state phenotype. The molecular abnormality demonstrated in this family provides evidence that defective synthesis of GP Ibα alters the membrane expression of the GP Ib-IX complex and may be responsible for Bernard-Soulier syndrome

From the earlier "body" poetry of Extraits du corps , where the image of the inward-looking eye makes its appearance, to his book on Magritte's "visible thought" and the prose text Le 19 octobre 1977 , where he thematizes the functioning of perception, Noël explores the complex interplay between seeing and thought, language and thought, and seeing and writing. This study analyzes these and other major issues driving Noel's poetics.

  6. Dark Ages Religious Conflicts and their Literary Representations: The Winter King, by Bernard Cornwell

    Directory of Open Access Journals (Sweden)

    Carlos A. Sanz Mingo

    2011-07-01

    Full Text Available This paper analyses the religious situation in Britain in the fifth and sixth centuries as reflected in Arthurian literature. This reflection usually depicts religious strife which brought a political division between the British kingdoms. This, in turn, provoked the final defeat against the Anglo-Saxons. Four religious creeds will be dealt with: the native Celtic religion and the cults that the Romans brought with them from the Eastern Mediterranean, including Christianity and the mysteries of Isis and Mithras. All of them are represented in Bernard Cornwell’s trilogy The WarlordChronicles. We will concentrate on how these creeds influenced the lives of Britons in the agerepresented and exemplified in the first book of Conrnwell’s trilogy, The Winter King. Despite thefact that religion has always been one of the most common topics in Arthuriana, modern literaturedeals with it in a different way to previous texts, linking it with history and politics.

    The Edward Mellen Press: Lewiston, NY, 1998. 114 pp + index. ISBN 0-7734-8284-9. $69.95. There may not be a surname better known to students of chemistry than Lewis, from the Lewis electron-dot diagrams and the Lewis theory of acids and bases. More advanced students may know of the groundbreaking textbook Thermodynamics, by Lewis and Randall. Yet few Americans know much about this remarkable U.S.-born scholar, whose contributions equal those of the greatest scientists. He is a chemist-educator of whom we should be as proud and as well informed as we are of Linus Pauling, who was part of the westward movement of science in this country that G. N. Lewis began, or of the recently deceased Glenn Seaborg, who was one of the many students of Lewis who achieved renown. Gilbert N. Lewis was born in Weymouth, Massachusetts, in 1875, but his family moved to near Lincoln, Nebraska, in 1884. He spent two years at the University of Nebraska, but then moved to Harvard when his father became an executive at Merchants Trust Company in Boston. Young Lewis (then only 17) was also said to have been disappointed with the quality of education in Nebraska, and this may have been part of the impetus for the family's move east. After earning his baccalaureate at Harvard, he taught for a year at Phillips Andover Academy before returning to Harvard to study for his doctorate, which he completed 100 years ago, in 1899, under T. W. Richards. Lewis's doctoral work was on the thermodynamics of zinc and cadmium amalgams. At that time, physical chemistry was only beginning to achieve recognition as a branch of science, and its boundaries were ill defined. Edward Lewis quotes his father as often saying, "Physical chemistry is anything interesting." Like many chemists of his time, Lewis went to Europe to complete his preparation for a career; he was in the laboratories of Ostwald in Leipzig and Nernst in Göttingen in 1900-1901. On his return to the United States, he was an instructor at Harvard

    The Global Geophysical Fluids Center of the International Earth Rotation Service (IERS) comprises 8 special bureaus, one of which is the Special Bureau for Tides. Its purpose is to facilitate studies related to tidal effects in earth rotation. To that end it collects various relevant datasets and distributes them, primarily through its website at bowie.gsfc.nasa.gov/ggfc/tides. Example datasets include tabulations of tidal variations in angular momentum and in earth rotation as estimated from numerical ocean tide models and from meteorological reanalysis products. The web site also features an interactive tidal prediction "machine" which generates tidal predictions (e.g., of UT1) from lists of harmonic constants. The Special Bureau relies on the tidal and earth-rotation communities to build and enlarge its datasets; further contributions from this community are most welcome.

    Full Text Available The paper “C. S. Lewis: The Romantic Rationalist” presents the way C. S. Lewis gives an account in his first fictional (allegorical book, The Pilgrim’s Regress, of how he discovered Christianity on the converging paths of romanticism and rationalism. The outstanding scholar and author whose intellectual and spiritual development has turned him into one of the most influential Christian writers of the twentieth century became an atheist in his teens and after a long journey through different philosophical convictions he converted to Christianity in his early thirties, a change that affected his entire work. His love of literature was essential in discovering both the rational and the imaginative appeal of Christianity, which led him into a vision of the reality of the world and of life that satisfied the longing of his heart and the hunger of his imagination.

    2002-01-01

    We report the occurrence of Capgras' syndrome, or the delusion of doubles, in a patient with dementia with Lewy bodies. The patient believed that several similar-looking impostors had replaced his wife of over 50 years. Uncharacteristically, he adopted a friendly attitude with these impostors. This unusual convivial reaction to the impostors may result from differential involvement of the dual visual pathways processing facial recognition and emotional responses to faces. The delusion resolved spontaneously, coincident with worsening of the dementia. In a retrospective chart review of 18 autopsy-confirmed cases of dementia with Lewy bodies, delusions were reported in 5 subjects (27.8%), of whom 1 had misidentification delusions much like Capgras' syndrome.

    Reid's mth-order generalized Ermakov systems of nonlinear coupling constant α are equivalent to an integrable Emden–Fowler equation. The standard Ermakov–Lewis invariant is discussed from this perspective, and a closed formula for the invariant is obtained for the higher-order Reid systems (m≥3). We also discuss the parametric solutions of these systems of equations through the integration of the Emden–Fowler equation and present an example of a dynamical system for which the invariant is equivalent to the total energy. - Highlights: • Reid systems of order m are connected to Emden–Fowler equations. • General expressions for the Ermakov–Lewis invariants both for m=2 and m≥3 are obtained. • Parametric solutions of the Emden–Fowler equations related to Reid systems are obtained.

    1987-01-01

    The NASA Lewis Research Center supports many research facilities with many isolated buildings, including wind tunnels, test cells, and research laboratories. These facilities are all located on a 350 acre campus adjacent to the Cleveland Hopkins Airport. The function of NASA-Lewis is to do basic and applied research in all areas of aeronautics, fluid mechanics, materials and structures, space propulsion, and energy systems. These functions require a great variety of remote high speed, high volume data communications for computing and interactive graphic capabilities. In addition, new requirements for local distribution of intercenter video teleconferencing and data communications via satellite have developed. To address these and future communications requirements for the next 15 yrs, a project team was organized to design and implement a new high speed communication system that would handle both data and video information in a common lab-wide Local Area Network. The project team selected cable television broadband coaxial cable technology as the communications medium and first installation of in-ground cable began in the summer of 1980. The Lewis Information Network (LINK) became operational in August 1982 and has become the backbone of all data communications and video.

    The Lewis Educational and Research Collaborative Internship Program (LERCIP) is a collaborative undertaking by the Office of Educational Programs at NASA Glenn Research Center at Lewis Field (formerly NASA Lewis Research Center) and the Ohio Aerospace Institute. This program provides 10-week internships in addition to summer and winter extensions if funding is available and/or is requested by mentor (no less than 1 week no more than 4 weeks) for undergraduate/graduate students and secondary school teachers. Students who meet the travel reimbursement criteria receive up to $500 for travel expenses. Approximately 178 interns are selected to participate in this program each year and begin arriving the fourth week in May. The internships provide students with introductory professional experiences to complement their academic programs. The interns are given assignments on research and development projects under the personal guidance of NASA professional staff members. Each intern is assigned a NASA mentor who facilitates a research assignment. In addition to the research assignment, the summer program includes a strong educational component that enhances the professional stature of the participants. The educational activities include a research symposium and a variety of workshops, and lectures. An important aspect of the program is that it includes students with diverse social, cultural and economic backgrounds. The purpose of this report is to document the program accomplishments for 2004.

    The increasing demand for a low-cost, reliable way to launch commercial payloads to low- Earth orbit has led to the need for inexpensive, expendable propulsion systems for new launch vehicles. This, in turn, has renewed interest in less complex, uncooled rocket engines that have combustion chambers and exhaust nozzles fabricated from ablative materials. A number of aerospace propulsion system manufacturers have utilized NASA Lewis Research Center's test facilities with a high degree of success to evaluate candidate materials for application to new propulsion devices.

    The measured 222 Rn/ 226 Ra ratio in bone following 226 Ra injection of 5-year-old mature beagles and adult St. Bernards was similar to that predicted by an equation derived from data of beagles injected as young adults. However, Rn/Ra ratios were significantly lower in beagles injected as 3-month-old juveniles for about the first 600 days after injection, but were indistinguishable thereafter from the values predicted by the equation associated with young adult beagles. A 2-term equation was developed from the data for juveniles, the first term of which was the equation for young adults. For beagles injected as juveniles, the skeletal Rn/Ra ratio as a function of time after injection (t, in days) was Rn/Ra = 0.075 t 0 158 (1-e/sup -0.181t/) - 0.058 (e/sup -0.0061t/-e/sup -0.162t/). Beagles injected as 2-day-old neonates exhibited ratios for the first 2 weeks which were similar enough to those of juveniles that a separate equation was not derived for neonatal beagles

    Torres, Sheila M F; Brien, Timothy O; Scott, Danny W

    2002-10-01

    Arteritis of the nasal philtrum is described in four dogs. Two of the Saint Bernards were related. The lesions were solitary, well-circumscribed, linear ulcers that were neither pruritic nor painful. The age of the dogs at the time the owners first noticed the lesion ranged from 3 to 6 years. The ulcers had been present for 0.5-5 years before diagnosis was pursued. Three of the dogs experienced repeated, mild episodes of arterial bleeding from the ulcers. Two dogs also experienced a severe episode of bleeding that required surgical intervention. Histopathological findings included a V-shaped ulcer, neutrophilic dermal inflammation subjacent to the ulcer and lymphoplasmacytic dermatitis bordering the ulcer. The most remarkable pathological findings were present in the deep dermal arteries and arterioles subjacent to the ulcer. The changes were characterized by subendothelial spindle cell proliferation with marked extracellular matrix deposition that stained blue with Alcian Blue (mucin) and Masson's trichrome (collagen) and resulted in intimal thickening, and stenosis of dermal arteries and arterioles. Immunohistochemical studies suggested that the proliferating spindle cells were of either myofibroblast or smooth muscle origin (actin and vimentin positive). Anti-inflammatory therapy (glucocorticoids; tetracycline and niacinamide; fish oil) may be beneficial for long-term control of this condition, however, long-term maintenance treatment appears to be necessary.

    2018-04-01

    Full Text Available La Casa –or in English, the house– that Bernard Rudofsky built on the Spanish Mediterranean coast in 1971 is a valuable case study on the operational possibilities of popular architecture in the practice of this contemporary discipline. It is a repository of theoretical references typical of the vernacular world; its author, known for the exhibition Architecture without Architects, is emblematic of this type of architecture to which he dedicated much of his efforts as a theorist and polemicist throughout the course of his life. Additionally, La Casa is a unique architectural feat as it involves the practical materialization of its implicated theoretical position. It is possible that a concrete conclusion can be drawn from this case, which may shed light on the possible operability of a type of architecture that presents more than a few difficulties for the current context of the discipline, despite being habitually admired and praised. Additionally, the text presented here brings to light unpublished information found in the personal diaries of the architect that allows for the recreation of the circumstances surrounding the ideation and construction of this piece of architecture.

Il campo su cui questa analisi intende muoversi è delimitato principalmente da due testi fondamentali come Vergogna e Necessità e l’introduzione alla nuova edizione del 2001, insieme alla prima parte, de La fragilità del bene. Si cercherà di mostrare lo scarto tra queste due diverse concezioni riconducendo ad ognuna il particolare atteggiamento etico che sostiene; di questi diversi punti di vista si cercherà di ricostruire il nesso con le differenti interpretazioni che i due autori forniscono dell’Agamennone di Eschilo e con le diverse reazioni che motivano nei confronti del protagonista e della sua vicenda. Gli obiettivi delle argomentazioni che seguono sono principalmente due: innanzitutto evidenziare come in alcune delle critiche mosse dalla filosofa americana al collega britannico siano rinvenibili spunti fondamentali per quella che si ritiene una più completa comprensione della tragedia come caso limite del conflitto tra soggetto etico e mondo e, in secondo luogo, produrre una giustificazione filosofica ulteriore della reazione motivata da Nussbaum davanti alla condotta di Agamennone che sia compatibile con l’approccio di Williams attraverso una riproposizione del conflitto di valori in termini di conflitto di ruoli.

    Full Text Available Este artículo indaga en algunos aspectos de la antropología filosófica expuesta en la obra del francés Henri Bergson. Para ello, nos serviremos de la confrontación de su doctrina original con la de un bergsoniano sui generis, el intelectual y dramaturgo irlandés George Bernard Shaw. El Prefacio. A medio siglo infiel, de Shaw, incluido en su obra más ambiciosa, Vuelta a Matusalén. Un Pentateuco Metabiológico, de 1921, será el texto base con el que haremos dialogar a Bergson con este periférico bergsonismo. Tomaremos como hilo conductor la teoría sobre el hábito, en el contexto de la metafísica de la evolución de los seres orgánicos, y lo llevaremos hasta el concepto límite, que parece conciliar ambas posturas: la idea de muerte superable. Ni en Bergson ni en Shaw los hábitos (la Cultura forman parte integral de la esencia del hombre, y la muerte (cuestión en la que Bergson es mucho más elusivo juega en ellos un rol anfibio, entre Cultura y Naturaleza.

    I. Bernard Cohen (1914-2003), the first American to receive a Ph.D. in history of science, was a Harvard undergraduate ('37) and then a Ph.D. student and protégé of George Sarton, founder of Isis and the History of Science Society. He went on to succeed Sarton as editor of Isis (1952-1958) and, later, president of the Society (1961-1962); he was also a president of the International Union of the History and Philosophy of Science. Cohen was an internationally recognized Newton scholar; his interests were encyclopedic, ranging from science and public policy to the history of computers, with several decades as a special consultant for history of computing with IBM. Among his hundreds of publications were such major books as Franklin and Newton (1956), The Birth of a New Physics (1959; rpt., 1985), The Newtonian Revolution (1980), Revolution in Science (1985), Science and the Founding Fathers (1995), Howard Aiken: Portrait of a Computer Pioneer (1999), and his last book, The Triumph of Numbers (2005), not to mention two jointly authored contributions, the variorum edition and new English translation of Newton's Principia, which will surely still be read a century from now.

    After Hurricane Katrina struck the Gulf Coast of the United States on 29 August 2005, it became obvious that the country was facing an enormous national emergency. With local resources overwhelmed, governors across the US responded by deploying thousands of National Guard soldiers and airmen. The National Guard has responded to domestic disasters due to natural hazards since its inception, but an event with the magnitude of Hurricane Katrina was unprecedented. The deployment of >900 Army National Guard soldiers to St. Bernard Parish, Louisiana in the aftermath of the Hurricane was studied to present some of the operational issues involved with providing medical support for this type of operation. In doing so, the authors attempt to address some of the larger issues of how the National Guard can be incorporated into domestic disaster response efforts. A number of unforeseen issues with regards to medical operations, medical supply, communication, preventive medicine, legal issues, and interactions with civilians were encountered and are reviewed. A better understanding of the National Guard and how it can be utilized more effectively in future disaster response operations can be developed.

    Full Text Available This essay looks at the late Lewis Binford’s career from the standpoint of sociology of science. His thinking and manner reflect his socialization in Virginia Baptist subculture. As convinced of his authority on science as Jerry Falwell was of his authority on Biblical morality, Lewis Binford and his third wife Sally Rosen Binford excited a group of 1960s students to follow Lewis in an outmoded version of science (hypothetico-deductive and in trusting statistics. The “frames of reference” he laboriously constructed are naïve on environmental interpretation and, because he expressed contempt for “political” aspects of archaeology, fail to take into account effects of colonialism. His work is often scientistic, in the “modern” mode that historian Dorothy Ross describes as characteristic of twentieth-century American social sciences.

    2011-01-01

    Full Text Available Bernard-Soulier syndrome belongs to congenital thrombocytopathic platelet disorders. There is a change of the structure of the glycoprotein in platelet membrane, causing the impair of platelet adherence on the blood vessel wall. This syndrome is clinically manifested by spontaneous bleeding in the skin and mucosa. The prognosis is usually good with an adequate support, but serious bleeding episodes occur during menstruation, trauma or surgery intervention. Treatment of bleeding or prophylaxis during surgical intervention is usually based upon platelet transfusion and the use of antifibrinolitic drugs. The object of case report is the significance of the right and an adequate preparation for the operational treatment: Mrs 42 year old, with diagnosis: Bernard-Soulier thrombocytopathia. Iron deficiency anemia. Status post operationem cystis ovarii sinistri. Admitted to the Clinic of gynaecology and obstetrics 'Narodni front' for operative treatment. The menstrual cycle is on 28 days, duration 7 days. From juvenile period there were reports of episodes of bleeding with thrombocytopathia. In prepartal period transfused with few doses of platelet. All dental interventions followed with bleeding, done with 6 doses of platelet concentrate. The history of operation of a cyst with a diagnosis: Cysta ovarii lateralis dextri torquata in 2005. The operation followed with pre-operative use of 15 doses of platelet concentrate, 2 units of fresh frosen plasm and 3 units of deplasmatic erythrocytes. There was a report of adverse reaction due to plasm transfusion and erythrocytes as a hypersensitive reaction, but during operation, there was no bigger post-operative bleeding. In following 2 years, the patient was hospitalized few times because of seriuos menometrorrhagia, and conservativly treated with iron preparations, with a difficult tolerating. Anamnesis: allergy to preparation of salicylate, ranitidin, diclofenac and tranexamic acid. In last hospitalization

    Daniele Francesconi

    2009-01-01

    Full Text Available In this paper I deal with Bernard Mandeville's views on political economy, in order to reconstruct his overall perspectives on individual moral psychology and on the topic of luxury. First, I discuss Mandeville's views on labour, wages, political management and the balance of trade against the background of contemporary paradigms of 'mercantilism' and 'free trade'. I argue that he freely moved between these categories, and I also contend that they can not be taken as a rigid orthodoxy, which would prevent a real historical recovery of their meaning. Then I turn to his discussion of luxury. I maintain that this aspect of Mandeville's thought can not be reduced to a paradoxical provocation (however brilliant, but must be reconstructed along a three-dimensional framework, because Mandeville elaborated the relative difference between needs and desires in three contexts. This framework was not explicitly stated by Mandeville, but can be recosntructed through a close reading of his writings: first, an international context, in which certain countries specialised in exporting, whereas others in consuming, luxury goods; secondly, a social context, in which the differentiation between luxuries and wants mirrors a social hierarchy; and finally an evolutionary dimension, in which the consumption of luxury goods helps spread benefits to all social ranks in the next generations. In a final section I reconsider the classic question of Mandeville's role in the growth of political economy and his alledged theory of 'possessive individualism' coupled with classical liberalism. I disagree with those reconstructions that take for granted the attendant rise of free trade, individualism and liberalism. Mandeville is a crucial case in point for showing how economic arguments were still strictly interwoven with insights in moral psychology, party politics and social criticism.

  1. Obstetric and gynecological intervention in women with Bernard-Soulier syndrome: Report of two cases

    Full Text Available Introduction. Bernard-Soulier syndrome (BSS is a rare inherited bleeding disorder characterized by giant platelets thrombocytopenia e prolonged bleeding timee frequent hemorrhages with considerable morbidity. Data on the outcome of pregnancy and gynecological intervention in BSS are rare and there are no general therapeutic recommendations. Cases Outline. We report two cases of BSS. In the first case a 29-year-old patient with BSS was admitted in 8 weeks of gestation. The diagnosis of BSS was made on the basis of prolonged bleeding time, giant-platelets thrombocytopenia, and absent ristocetin-induced platelet aggregation. In 38 week of gestation Cesarean section, with platelets transfusion preparation, was performed. Obstetric intervention passed without complication. Postoperative course was complicated with a three-week vaginal bleeding resistant to platelet transfusion. Neonate platelet count was normal. Our second case was a 28-year-old patient with BSS, hospitalized for ovarial tumor surgery. The patient was prepared for the intervention with platelets transfusion. The surgery was uncomplicated, but on the second postoperative day a massive vaginal bleeding, resistant to the platelet transfusion, developed. Bleeding control was achieved with activated recombinant factor VII. Twelve hours the patient developed later hypertensive crisis with epileptic seizure due to subarachnoid hemorrhage. Therapy was continued with platelet transfusion, antihypertensive and antiedema drugs. PH examination of tumor tissue showed hemorrhagic ovarial cyst. Conclusion. Obstretic and gynecological intervention in women with BSS may be associated with a life-threatening bleeding thus requiring a multidisciplinary approach with adequate preparation. Because of the limited data in the literature, it is not possible to provide firm management recommendations and each case should be managed individually.

  2. [Clinical Neuropsychology of Dementia with Lewy Bodies].

    2016-02-01

    Dementia with Lewy bodies (DLB) shows lesser memory impairment and more severe visuospatial disability than Alzheimer disease (AD). Although deficits in both consolidation and retrieval underlie the memory impairment, retrieval deficit is predominant in DLB. Visuospatial dysfunctions in DLB are related to the impairments in both ventral and dorsal streams of higher visual information processing, and lower visual processing in V1/V2 may also be impaired. Attention and executive functions are more widely disturbed in DLB than in AD. Imitation of finger gestures is impaired more frequently in DLB than in other mild dementia, and provides additional information for diagnosis of mild dementia, especially for DLB. Pareidolia, which lies between hallucination and visual misperception, is found frequently in DLB, but its mechanism is still under investigation.

    To report unusual electrophysiologic data in a patient with Tangier disease in an effort to better understand the pathophysiologic features of the peripheral nerve lesions in this disease. Case report. A 15-year-old girl had subacute onset of asymmetric neuropathy with persistent conduction block, resembling Lewis-Sumner syndrome. Electrophysiologic data in Tangier disease. After initially unsuccessful treatment with intravenously administered immunoglobulins, the finding of an abnormal lipid profile led to the diagnosis of Tangier disease due to the R587W mutation in the adenotriphosphate-binding cassette transporter-1 gene (ABCA1) (OMIM 9q22-q31). Conduction block, which is the electrophysiologic hallmark of focal demyelination, can be present in Tangier disease. It could be induced by focal nerve ischemia or by preferential lipid deposition in the paranodal regions of myelinated Schwann cells. The presence of a conduction block in Tangier disease may lead to a misdiagnosis of dysimmune neuropathy.

    Directory of Open Access Journals (Sweden)

    Maarja Hollo

    2012-04-01

    Full Text Available The aim of this article is to explore how a sense of place informs the autobiographical in the work of Bernard Kangro. In order to establish a wider context for the relationship between the writer in exile, writing, and a sense of place there is a reference to the work and literary views of the German-speaking Jewish poet Paul Celan. The common basis for the comparison of the work of the two writers is their exile status, but they also share an understanding of the interrelationship between language and reality, a distinctive relationship with places and a sense of place as well as religiousness in their work. The current article focuses on the depiction of places and a sense of place, and its associations with exile as a state of mind that heightens the sensitivity to the real places experienced in the past as well as the imaginary places experienced in the present. In the description of places and a sense of place the autobiographical element occurs on two levels. Firstly, an autobiographical reading is made possible by the proper names in the text that signify real geographical places, which allow for a positivist interpretation with regard to the author’s biography. Secondly, the autobiographical may be revealed through certain figures in Kangro’s work, which are repeated from work to work but whose meaning might be diametrically opposite. Such recurrent figures are, for example, those of the island, the sea, the land, the tree, fog, snow, the wind, the bog, the sky, and the star. The present article addresses the figure of the island and the shifting scale of meanings it creates in Kangro’s work. An approach to the autobiographical via textual tropes is based on Paul de Man’s consideration of autobiography, who was against defining autobiography as a genre or a mode but viewed it instead as “a figure of reading or of understanding that can occur in all texts”. In Kangro’s texts three kinds of islands are found: islands

  9. C. S. Lewis, Reluctant Convert and (not so Ordinary Anglican

    Directory of Open Access Journals (Sweden)

    Mănăstireanu Dănuţ

    2014-12-01

    Full Text Available After some passing considerations on the reception of Lewis in Romania, the present paper discusses the role played by Anglicanism in the late personal commitment of C.S. Lewis to the Christian faith, after years of atheism, scepticism, and agnosticism. It argues that in fact Anglicanism contributed very little to Lewis’s (reconversion to Christianity. Furthermore, the paper agrees with the generally accepted idea that the particular calling that Lewis felt he had, that of being a Christian apologist, made him wary of being associated with the defence of any specific Christian tradition. In virtue of this special calling, Lewis also reacted quite strongly against certain aspects of Anglicanism, like, for instance, the ordination of women to priesthood, which he perceived as an obstacle to ecumenism and, implicitly, to an effective defence of the Christian faith in the public arena. In spite of all this, there is little doubt that Lewis has fully and unreservedly adopted Anglicanism as his preferred version of Christianity. From this particular stance, the life and ministry of C.S. Lewis made a huge public impact in the twentieth century and beyond. In light of the undeniable influence he had on the intellectual and religious scene in the last hundred years, one may ask not so much how Anglican was Lewis, but, rather, ‘why isn’t Anglicanism more like Lewis’.

  10. Utilizing NASA EOS to Assist in Determining Suitable Planting Locations for Bottomland Hardwood Trees in St. Bernard Parish, Louisiana

    St. Bernard Parish, located in southeast Louisiana, is rapidly losing coastal forests and wetlands due to a variety of natural and anthropogenic disturbances (e.g. subsidence, saltwater intrusion, low sedimentation, nutrient deficiency, herbivory, canal dredging, levee construction, spread of invasive species, etc.). After Hurricane Katrina severely impacted the area in 2005, multiple Non-Governmental Organizations (NGOs) have focused not only on rebuilding destroyed dwellings, but on rebuilding the ecosystems that once protected the citizens of St. Bernard Parish. Volunteer groups, NGOs, and government entities often work separately and independently of each other and use different sets of information to choose the best planting sites for restoring coastal forests. Using NASA Earth Observing Systems (EOS), Natural Resource Conservation Service (NRCS) soil surveys, and ancillary road and canal data in conjunction with ground truthing, the team created maps of optimal planting sites for several species of bottomland hardwood trees to aid in unifying these organizations, who share a common goal, under one plan. The methodology for this project created a comprehensive Geographic Information System (GIS) to help identify suitable planting sites in St. Bernard Parish. This included supplementing existing elevation data using Digital Elevation Models derived from LIDAR data, and determining existing land cover in the study area from classified Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) imagery. Airborne Visible/Infrared Imaging Spectrometer (AVIRIS) data from a single low-altitude swath was used to assess the health of vegetation over an area near the Mississippi River Gulf Outlet Canal (MRGO) and Bayou La Loutre. Historic extent of coastal forests was also mapped using aerial photos collected between 1952 and 1956. The final products demonstrated yet another application of NASA EOS in the rebuilding and monitoring of coastal ecosystems in

  11. Bruised witness: Bernard Spilsbury and the performance of early twentieth-century English forensic pathology.

    Science.gov (United States)

    Burney, Ian; Pemberton, Neil

    2011-01-01

    This article explores the status, apparatus and character of forensic pathology in the inter-war period, with a special emphasis on the 'people's pathologist', Bernard Spilsbury. The broad expert and public profile of forensic pathology, of which Spilsbury was the most prominent contemporary representative, will be outlined and discussed. In so doing, close attention will be paid to the courtroom strategies by which he and other experts translated their isolated post-mortem encounters with the dead body into effective testimony. Pathologists built a high-profile practice that transfixed the popular, legal and scientific imagination, and this article also explores, through the celebrated 1925 murder trial of Norman Thorne, how Spilsbury's courtroom performance focused critical attention on the practices of pathology itself, which threatened to destabilise the status of forensic pathology. In particular, the Thorne case raised questions about the interrelation between bruising and putrefaction as sources of interpretative anxiety. Here, the question of practice is vital, especially in understanding how Spilsbury's findings clashed with those of rival pathologists whose autopsies centred on a corpse that had undergone further putrefactive changes and that had thereby mutated as an evidentiary object. Examining how pathologists dealt with interpretative problems raised by the instability of their core investigative object enables an analysis of the ways in which pathological investigation of homicide was inflected with a series of conceptual, professional and cultural difficulties stemming in significant ways from the materiality of the corpse itself. This article presents early findings of a larger study of twentieth-century English homicide investigation which focuses on the interaction between two dominant forensic regimes: the first, outlined in part here, is a body-centred forensics, associated with the lone, 'celebrity' pathologist, his scalpel and the mortuary

    1998-01-01

    The NASA Lewis Research Center's Learning Technologies Project (LTP) has responded to requests from local school district technology coordinators to provide content for videoconferencing workshops. Over the past year we have offered three teacher professional development workshops that showcase NASA Lewis-developed educational products and NASA educational Internet sites. In order to determine the direction of our involvement with distance learning, the LTP staff conducted a survey of 500 U.S. schools. We received responses from 72 schools that either currently use distance learning or will be using distance learning in 98-99 school year. The results of the survey are summarized in the article. In addition, the article provides information on distance learners, distance learning technologies, and the NASA Lewis LTP videoconferencing workshops. The LTP staff will continue to offer teacher development workshops through videoconferencing during the 98-99 school year. We hope to add workshops on new educational products as they are developed at NASA Lewis.

  18. I-Metaiodobenzylguanidine Myocardial Scintigraphy in Lewy Body-Related Disorders: A Literature Review

    Full Text Available Lewy body-related disorders are characterized by the presence of Lewy bodies and Lewy neurites, which have abnormal aggregations of α-synuclein in the nigral and extranigral areas, including in the heart. 123I-metaiodobenzylguanidine (MIBG scintigraphy is a well-known tool to evaluate cardiac sympathetic denervation in the Lewy body-related disorders. MIBG scintigraphy showed low uptake of MIBG in the Lewy body-related disorders, including Parkinson’s disease, dementia with Lewy bodies, pure autonomic failure and rapid eye movement sleep behavior disorder. This review summarizes previous results on the diagnostic applications of MIBG scintigraphy in Lewy body-related disorders.

  19. FROM MRS WARREN’S PROFESSION TO PRESS CUTTINGS: THE WOMAN QUESTION IN GEORGE BERNARD SHAW’S PLAYS

    2017-06-01

    Full Text Available George Bernard Shaw, who introduced social realism to the British stage, is considered to be the most significant playwright of the Victorian era. In his plays, he challenged the typical Victorian representation of female characters and introduced a new woman type who stands as a powerful and independent figure. Shaw’s female characters can be analysed in line with the suffragette movement, the fight given by British women to gain their right to vote. In this regard, Shaw’s play Mrs Warren’s Profession exemplifies a female character who can be considered as an advocate for female liberation and power. On the other hand, his play Press Cuttings, which was specifically written to support the suffragette movement, neither exemplifies the new woman image presented by Shaw in his plays nor contributes to the suffragette movement. Hence, this study aims to discuss the theme of the rights of women and to focus on George Bernard Shaw’s Mrs Warren’s Profession and Press Cuttings by means of Shaw’s involvement in and support for the suffragette movement from the Victorian to the Edwardian era.

    2004-05-05

    We describe examples of highly regio- and enantioselective nitrile oxide cycloadditions to unsaturated alkenes using substoichiometric amounts of a chiral Lewis acid. Pyrazolidinones proved to be effective achiral templates in the cycloadditions providing C-adducts typically in >30:1 selectivity and 80-99% ee. To avoid potential problems involving coordination of the Lewis acid by amine bases, we have devised a novel method for the generation of unstable nitrile oxides from hydroximinoyl chlorides using Amberlyst 21 as the base.

  2. Tribute to Erwin Felix Lewy-Bertaut

    International Nuclear Information System (INIS)

    2006-01-01

    Erwin Lewy (alias Felix Bertaut) was born in 1913 in Germany, he emigrated to France where he undertook graduate studies in chemistry. Then, he joined the powder central laboratory where he learnt how to use international tables for structure determination. His thesis work was the X-ray study of the statistical distribution of the size of iron grains. The method Bertaut developed is still a reference in powder granulometry. Bertaut was also interested in the nascent neutron diffraction method and he flew to the United-States to improve his knowledge on this topic. Felix Bertaut created the neutron diffraction laboratory in the atomic research center in Grenoble and later he headed the CNRS' crystallography laboratory till 1982. Felix Bertaut and his laboratories became internationally renowned in crystallography, neutron diffraction and magnetism. He favored the scientific cooperation between France and Germany that led to the creation of the Laue-Langevin Institute (ILL). The ILL became European and was a key partner for building the European Synchrotron Facility (ESRF) in Grenoble. Bertaut was elected as a full member of the French Academy of Sciences in 1979, he died in 2003. (A.C.)

The work of the Center is directed toward new propulsion, power, and communications technologies for application to aeronautics and space, so that U.S. leadership in these areas is ensured. The end product is knowledge, usually in a report, that is made fully available to potential users--the aircraft engine industry, the energy industry, the automotive industry, the space industry, and other NASA centers. In addition to offices and laboratories for almost every kind of physical research in such fields as fluid mechanics, physics, materials, fuels, combustion, thermodynamics, lubrication, heat transfer, and electronics, LeRC has a variety of engineering test cells for experiments with components such as compressors, pumps, conductors, turbines, nozzles, and controls. A number of large facilities can simulate the operating environment for a complete system: altitude chambers for aircraft engines; large supersonic wind tunnels for advanced airframes and propulsion systems; space simulation chambers for electric rockets or spacecraft; and a 420-foot-deep zero-gravity facility for microgravity experiments. Some problems are amenable to detection and solution only in the complete system and at essentially full scale. By combining basic research in pertinent disciplines and generic technologies with applied research on components and complete systems, LeRC has become one of the most productive centers in its field in the world. This brochure describes a number of the facilities that provide LeRC with its exceptional capabilities.

  4. Lewy body dementia--clinical, pathological and neurochemical interconnections.

    Science.gov (United States)

    Perry, R; McKeith, I; Perry, E

    1997-01-01

    Senile dementia of Lewy body type or Lewy body dementia (SDLT or LBD) is defined as a Lewy body associated disease presenting in the elderly primarily with dementia with variable extrapyramidal disorder. Characteristic clinical symptoms include fluctuating cognitive impairment, psychotic features such as hallucinations and a particular sensitivity to neuroleptic medication. Although apolipoprotein e4 allele is increased 2-3 fold in SDLT (as in Alzheimer's disease) and beta-amyloidosis occurs in most cases, the most robust neurobiological correlate of the dementia so far identified appears to be extensive cholinergic deficits in the neocortex. This is consistent with previously reported correlations between cortical cholinergic activity and dementia in Parkinson's disease (PD) and Alzheimer's disease. There is also a significant interaction between the density of limbic cortical Lewy bodies and dementia in both SDLT and PD, although the cortical neuronal population affected remains to be identified. Cortical Lewy body density is positively correlated with the age of disease onset in PD and SDLT. This may account for the increased incidence of psychiatric syndromes, as opposed to extrapyramidal disorder in Lewy body disease with advancing age as may age-related loss of cholinergic activity in cortical areas such as the hippocampus.

  5. Capgras syndrome in Dementia with Lewy Bodies.

    Capgras syndrome is characterized by the recurrent, transient belief that a person has been replaced by an identical imposter. We reviewed clinical characteristics of Dementia with Lewy Bodies (DLB) patients with Capgras syndrome compared to those without Capgras. We identified 55 consecutive DLB patients (11 cases with Capgras syndrome (DLB-C) and 44 cases without evidence of Capgras (DLB). Semi-structured interviews with the patient and an informant, neurological exams, and neuropsychological testing were performed. Caregivers were assessed for caregiver burden and depression. Primary comparisons were made between DLB-C and DLB. Exploratory analyses using stepwise logistic regression and bootstrap analyses were performed to determine clinical features associated with Capgras. DLB-C patients experienced more visual hallucinations and self-reported anxiety, had higher scores on the Neuropsychiatric Inventory, and were less likely to be treated with cholinesterase inhibitors at time of initial evaluation. Extrapyramidal symptoms and depression were not associated with Capgras. Caregivers of DLB-C patients had higher caregiver burden. DLB-C was associated with self-reported anxiety (OR = 10.9; 95% CI = 2.6-47.6). In a bootstrap analysis, clinical findings that were predictors of Capgras included visual hallucinations (log(OR) = 18.3; 95% CI = 17.9-19.3) and anxiety (log(OR) = 2.9; 95% CI = 0.31-20.2). Our study suggests that Capgras syndrome is common in DLB and usually occurs in the presence of anxiety and visual hallucinations, suggesting related etiopathogenesis. Early appreciation of Capgras syndrome may afford the opportunity to alleviate caregiver burden and improve patient and caregiver outcomes.

  6. Pareidolias: complex visual illusions in dementia with Lewy bodies.

    Patients rarely experience visual hallucinations while being observed by clinicians. Therefore, instruments to detect visual hallucinations directly from patients are needed. Pareidolias, which are complex visual illusions involving ambiguous forms that are perceived as meaningful objects, are analogous to visual hallucinations and have the potential to be a surrogate indicator of visual hallucinations. In this study, we explored the clinical utility of a newly developed instrument for evoking pareidolic illusions, the Pareidolia test, in patients with dementia with Lewy bodies-one of the most common causes of visual hallucinations in the elderly. Thirty-four patients with dementia with Lewy bodies, 34 patients with Alzheimer's disease and 26 healthy controls were given the Pareidolia test. Patients with dementia with Lewy bodies produced a much greater number of pareidolic illusions compared with those with Alzheimer's disease or controls. A receiver operating characteristic analysis demonstrated that the number of pareidolias differentiated dementia with Lewy bodies from Alzheimer's disease with a sensitivity of 100% and a specificity of 88%. Full-length figures and faces of people and animals accounted for >80% of the contents of pareidolias. Pareidolias were observed in patients with dementia with Lewy bodies who had visual hallucinations as well as those who did not have visual hallucinations, suggesting that pareidolias do not reflect visual hallucinations themselves but may reflect susceptibility to visual hallucinations. A sub-analysis of patients with dementia with Lewy bodies who were or were not treated with donepzil demonstrated that the numbers of pareidolias were correlated with visuoperceptual abilities in the former and with indices of hallucinations and delusional misidentifications in the latter. Arousal and attentional deficits mediated by abnormal cholinergic mechanisms and visuoperceptual dysfunctions are likely to contribute to the development

  7. Intralaminar nuclei of the thalamus in Lewy body diseases.

    2009-02-16

    Although the intralaminar thalamus is a target of alpha-synuclein pathology in Parkinson's disease, the degree of neuronal loss in Lewy body diseases has not been assessed. We have used unbiased stereological techniques to quantify neuronal loss in intralaminar thalamic nuclei concentrating alpha-synuclein pathology (the anterodorsal, cucullar, parataenial, paraventricular, central medial, central lateral and centre-median/parafascicular complex) in different clinical forms of Lewy body disease (Parkinson's disease with and without dementia, and dementia with Lewy bodies, N=21) compared with controls (N=5). Associations were performed in the Lewy body cases between intralaminar cell loss and the main diagnostic clinical (parkinsonism, dementia, fluctuation in consciousness, and visual hallucinations) and pathological (Braak stage of Parkinson's disease) features of these diseases, as well as between cell loss and the scaled severity of the alpha-synuclein deposition within the intralaminar thalamus. As expected, significant alpha-synuclein accumulation occurred in the intralaminar thalamus in the cases with Lewy body disease. Pathology concentrated anteriorly and in the central lateral and paraventricular nuclei was related to the Braak stage of Parkinson's disease, ageing, and the presence of dementia. Across all types of Lewy body cases there was substantial atrophy and neuronal loss in the central lateral, cucullar and parataenial nuclei, and neuronal loss without atrophy in the centre-median/parafascicular complex. Cases with visual hallucinations showed a greater degree of atrophy of the cucullar nucleus, possibly due to amygdala denervation. The significant degeneration demonstrated in the intralaminar thalamus is likely to contribute to the movement and cognitive dysfunction observed in Lewy body disorders.

  14. Of mice and men: evolution and the socialist utopia. William Morris, H.G. Wells, and George Bernard Shaw.

    Science.gov (United States)

    Hale, Piers J

    2010-01-01

    During the British socialist revival of the 1880s competing theories of evolution were central to disagreements about strategy for social change. In News from Nowhere (1891), William Morris had portrayed socialism as the result of Lamarckian processes, and imagined a non-Malthusian future. H.G. Wells, an enthusiastic admirer of Morris in the early days of the movement, became disillusioned as a result of the Malthusianism he learnt from Huxley and his subsequent rejection of Lamarckism in light of Weismann's experiments on mice. This brought him into conflict with his fellow Fabian, George Bernard Shaw, who rejected neo-Darwinism in favour of a Lamarckian conception of change he called "creative evolution."

  16. Lewy and his inclusion bodies: Discovery and rejection

    Directory of Open Access Journals (Sweden)

    Eliasz Engelhardt

    Full Text Available ABSTRACT Fritz Jacob Heinrich Lewy described the pathology of Paralysis agitans [Parkinson disease] and was the first to identify eosinophilic inclusion bodies in neurons of certain brain nuclei, later known as Lewy bodies, the pathological signature of the Lewy body diseases. In 1912, he published his seminal study, followed soon after by an update paper, and 10 years later, in 1923, by his voluminous book, where he exhaustively described the subject. The publication provided extensive information on the pathology of Paralysis agitans, and the entirely novel finding of eosinophilic inclusion bodies, which would become widely recognized and debated in the future. His discovery was acknowledged by important researchers who even named the structure after him. However, after his last publication on the issue, inexplicably, he never mentioned his histopathological discovery again. Despite several hypotheses, the reasons that led him to neglect (reject the structure which he so preeminently described have remained elusive.

    Molenaar, Joery P; Wilbers, Joyce; Aerts, Marjolein B; Leijten, Quinten H; van Dijk, Jan G; Esselink, Rianne A; Bloem, Bastiaan R

    2016-01-01

    We present a 75-year-old woman with dementia and parkinsonism who developed severe orthostatic hypotension and eventually died. Autopsy revealed extensive Lewy body formation in the midbrain, limbic system, intermediate spinal cord, and medulla oblongata. Furthermore, a vast amount of Lewy bodies was seen in the paravertebral sympathetic ganglia which likely explained the severe autonomic failure. We speculate that this autonomic failure caused sudden death through dysregulation of respiration or heart rhythm, reminiscent of sudden death in multiple system atrophy (MSA). Clinicians should be aware of this complication in patients presenting with parkinsonism and autonomic dysfunction, and that sudden death may occur in dementia with Lewy bodies (DLB) as it does in MSA.

His thesis work was the X-ray study of the statistical distribution of the size of iron grains. The method Bertaut developed is still a reference in powder granulometry. Bertaut was also interested in the nascent neutron diffraction method and he flew to the United-States to improve his knowledge on this topic. Felix Bertaut created the neutron diffraction laboratory in the atomic research center in Grenoble and later he headed the CNRS' crystallography laboratory till 1982. Felix Bertaut and his laboratories became internationally renowned in crystallography, neutron diffraction and magnetism. He favored the scientific cooperation between France and Germany that led to the creation of the Laue-Langevin Institute (ILL). The ILL became European and was a key partner for building the European Synchrotron Facility (ESRF) in Grenoble. Bertaut was elected as a full member of the French Academy of Sciences in 1979, he died in 2003. (A.C.)

  12. Lewis basicity of relevant monoanions in a non-protogenic organic solvent using a zinc(ii) Schiff-base complex as a reference Lewis acid.

    Science.gov (United States)

    Oliveri, Ivan Pietro; Di Bella, Santo

    2017-09-12

    Anions are ubiquitous species playing a primary role in chemistry, whose reactivity is essentially dominated by their Lewis basicity. However, no Lewis basicity data, in terms of Gibbs energy, are reported in the literature. We report here the first Lewis basicity of relevant monoanions through the determination of binding constants for the formation of stable 1 : 1 adducts, using a Zn II Schiff-base complex, 1, as a reference Lewis acid. Binding constants for equilibrium reactions were achieved through a nonlinear regression analysis of the binding isotherms from spectrophotometric titration data. The Lewis acidic complex 1 is a proper reference species because it forms stable adducts with both neutral and charged Lewis bases, thus allowing ranking their Lewis basicity. Binding constants indicate generally a strong Lewis basicity for all involved anions, rivalling or exceeding that of the stronger neutral bases, such as primary amines or pyridine. The cyanide anion results to be the strongest Lewis base, while the nitrate is the weaker base within the present anion series. Moreover, even the weaker base anions behave as stronger bases than the most common non-protogenic coordinating solvents.

    A Lewis cell was designed and constructed for investigating solvent extraction systems by spectrophotometrically monitoring both the organic and aqueous phases in real time. This new Lewis cell was tested and shown to perform well compared to other previously reported Lewis cell designs. The advantage of the new design is that the spectroscopic measurement allows determination of not only metal ion concentrations, but also information regarding chemical speciation—information not available with previous Lewis cell designs. For convenience, the new Lewis cell design was dubbed COSMOFLEX (COntinuous Spectroscopic MOnitoring of Forrest’s Liquid-liquid EXtraction cell).

  14. Is the Charcot and Bernard case (1883) of loss of visual imagery really based on neurological impairment?

    2011-11-01

    INTRODUCTION. The Charcot and Bernard case of visual imagery, Monsieur X, is a classic case in the history of neuropsychology. Published in 1883, it has been considered the first case of visual imagery loss due to brain injury. Also in recent times a neurological valence has been given to it. However, the presence of analogous cases of loss of visual imagery in the psychiatric field have led us to hypothesise functional origins rather than organic. METHODS. In order to assess the validity of such an inference, we have compared the symptomatology of Monsieur X with that found in cases of loss of visual mental images, both psychiatric and neurological, presented in literature. RESULTS. The clinical findings show strong assonances of the Monsieur X case with the symptoms manifested over time by the patients with functionally based loss of visual imagery. CONCLUSION. Although Monsieur X's damage was initially interpreted as neurological, reports of similar symptoms in the psychiatric field lead us to postulate a functional cause for his impairment as well.

  15. Effect of unequal fuel and oxidizer Lewis numbers on flame dynamics

    The interaction of non-unity Lewis number (due to preferential diffusion and/or unequal rates of heat and mass transfer) with the coupled effect of radiation, chemistry and unsteadiness alters several characteristics of a flame. The present study numerically investigates this interaction with a particular emphasis on the effect of unequal and non-unity fuel and oxidizer Lewis numbers in a transient diffusion flame. The unsteadiness is simulated by considering the flame subjected to modulations in reactant concentration. Flames with different Lewis numbers (ranging from 0.5 to 2) and subjected to different modulating frequencies are considered. The results show that the coupled effect of Lewis number and unsteadiness strongly influences the flame dynamics. The impact is stronger at high modulating frequencies and strain rates, particularly for large values of Lewis numbers. Compared to the oxidizer side Lewis number, the fuel side Lewis number has greater influence on flame dynamics. (author)

    Narrative discourse is an essential component of day-to-day communication, but little is known about narrative in Lewy Body spectrum disorder (LBSD), including Parkinson's disease (PD), Parkinson's disease with dementia (PDD), and dementia with Lewy bodies (DLB). We performed a detailed analysis of a semi-structured speech sample in 32 non-aphasic patients with LBSD, and we related their narrative impairments to gray matter (GM) atrophy using voxel-based morphometry. We found that patients with PDD and DLB have significant difficulty organizing their narrative speech. This was correlated with deficits on measures of executive functioning and speech fluency. Regression analyses associated this deficit with reduced cortical volume in inferior frontal and anterior cingulate regions. These findings are consistent with a model of narrative discourse that includes executive as well as language components and with an impairment of the organizational component of narrative discourse in patients with PDD and DLB.

    1992-11-01

    Recent reports have suggested that brain stem and cortical Lewy body formation may identify a neurodegenerative disorder in elderly demented individuals which accounts for up to 20% of cases of senile dementia coming to autopsy. Retrospective analysis of case notes of 21 autopsy patients with neuropathologically proven senile dementia of Lewy body type (SDLT) and 37 cases with neuropathologically proven Alzheimer's disease (AD) identified a characteristic clinical syndrome in SDLT. Fluctuating cognitive impairment; psychotic features including visual and auditory hallucinations, and paranoid delusions; depressive symptoms; falling and unexplained losses of consciousness were all seen significantly more often than in AD. Over half of the SDLT patients in this series who were given neuroleptics in standard dose showed acute and often irreversible adverse reactions indicative of a neuroleptic sensitivity syndrome. The survival time of drug treated patients was reduced by 50%. Operational criteria to aid in the clinical distinction between SDLT and AD patients are proposed and hypotheses regarding possible aetiology and treatment discussed.

    Chemical modification strategies to improve the mechanical properties of lignin-based polyurethanes are presented. We hypothesized that treatment of lignin with Lewis acids would increase the concentration of hydroxyl groups available to react with diisocyanate monomers. Under the conditions used, hydrogen bromide-catalyzed modification resulted in a 28% increase in hydroxyl group content. Associated increases in hydrophilicity of solvent-cast thin films were also recorded as evidenced by ...

In addition to the research assignment, the summer program includes a strong educational component that enhances the professional stature of the participants. The educational activities include a research symposium and a variety of workshops, lectures and short courses. An important aspect of the program is that it includes students with diverse social, cultural and economic backgrounds.

  5. Developing an approach for teaching and learning about Lewis structures

    Kaufmann, Ilana; Hamza, Karim M.; Rundgren, Carl-Johan; Eriksson, Lars

    2017-08-01

    This study explores first-year university students' reasoning as they learn to draw Lewis structures. We also present a theoretical account of the formal procedure commonly taught for drawing these structures. Students' discussions during problem-solving activities were video recorded and detailed analyses of the discussions were made through the use of practical epistemology analysis (PEA). Our results show that the formal procedure was central for drawing Lewis structures, but its use varied depending on situational aspects. Commonly, the use of individual steps of the formal procedure was contingent on experiences of chemical structures, and other information such as the characteristics of the problem given. The analysis revealed a number of patterns in how students constructed, checked and modified the structure in relation to the formal procedure and the situational aspects. We suggest that explicitly teaching the formal procedure as a process of constructing, checking and modifying might be helpful for students learning to draw Lewis structures. By doing so, the students may learn to check the accuracy of the generated structure not only in relation to the octet rule and formal charge, but also to other experiences that are not explicitly included in the formal procedure.

    Full Text Available Organic synthetic methodology in the 21st century aims to conform to the principles of green sustainable chemistry (GSC and we may expect that in the future, the realization of GSC will be an important objective for chemical industries. An important aim of synthetic organic chemistry is to implement waste-free and environmentally-benign industrial processes using Lewis acids as versatile as aluminum choride. A key technological objective of our work in this area has been to achieve a “catalyst recycling system that utilizes the high activity and structural features of fluorous Lewis acid catalysts”. Thus, we have developed a series of novel fluorous Lewis acid catalysts, namely the ytterbium(III, scandium(III, tin(IV or hafnium(IV bis(perfluoroalkanesulfonylamides or tris(perfluoro- alkanesulfonylmethides. Our catalysts are recyclable and effective for acylations of alcohols and aromatics, Baeyer-Villiger reactions, direct esterifications and transesterifications in a fluorous biphasic system (FBS, in supercritical carbon dioxide and on fluorous silica gel supports.

  7. Fullerene–Carbene Lewis Acid–Base Adducts

    KAUST Repository

    Li, Huaping

    2011-08-17

    The reaction between a bulky N-heterocylic carbene (NHC) and C60 leads to the formation of a thermally stable zwitterionic Lewis acid-base adduct that is connected via a C-C single bond. Low-energy absorption bands with weak oscillator strengths similar to those of n-doped fullerenes were observed for the product, consistent with a net transfer of electron density to the C60 core. Corroborating information was obtained using UV photoelectron spectroscopy, which revealed that the adduct has an ionization potential ∼1.5 eV lower than that of C60. Density functional theory calculations showed that the C-C bond is polarized, with a total charge of +0.84e located on the NHC framework and -0.84e delocalized on the C 60 cage. The combination of reactivity, characterization, and theoretical studies demonstrates that fullerenes can behave as Lewis acids that react with C-based Lewis bases and that the overall process describes n-doping via C-C bond formation. © 2011 American Chemical Society.

    1995-01-01

    A century separates the recent development of the National Biological Service (NBS) and an early predecessor, the Bureau of Biological Survey (BBS). Both organizations were established at critical crossroads for the conservation of the nation's living biological resources and are conservation landmarks of their times. The BBS of the 192()'s was described as 'a government Bureau of the first rank, handling affairs of great scientific, educational, social, and above all, economic importance throughout the United States and its outlying possessions'' (Cameron 1929:144-145). This stature was achieved at a time of great social, economic, and ecological change. BBS had the vision to pioneer new approaches that led to enhanced understanding of the relation between people, other living things, and the environment. The NBS faces similar challenges to address the issues of the 1990's and beyond.

    International Nuclear Information System (INIS)

    1997-01-01

    Throughout the year the Nuclear Safety Bureau (NSB) continued its regulatory approach to monitor and review the safety of nuclear plant operated by the Australian Nuclear Science and Technology Organisation (ANSTO). This included an ongoing regime of safety audits against the authorised arrangements in ANSTO's safety documentation and the bureau's expectations for nuclear plant drawn from international best practice. The NSB invited the participation of officers of the Australian Radiation Laboratory in these audits. Aspects of ANSTO's operation of nuclear plant reviewed by the NSB included training and accreditation of operations staff, abnormal occurrences, modifications to plant and emergency arrangements and exercises for the Lucas Heights Science and Technology Centre. Audits of HIFAR were also conducted on operating logs, radiation protection and radioactive discharges. Based on the reviews and audits conducted by the NSB, and ANSTO's actions in responding to the bureau's requests and requirements for actions, the NSB concluded that ANSTO's nuclear plant operated safely throughout the year, and that risks to on-site personnel and the public were maintained at acceptably low levels

    Some Lewis acid mediated reactions of Z-ligustilide (1), a bioactive constituent of the medicinal species Ligusticum porteri, were investigated. These reactions provided varying mixtures of Z-butylidenephthalide (7), E-butylidenephthalide (8), n-butyphthalide (13), and novel linear dimeric phthalides (9-12) as the main products. The formation of the dimers occurred in low yields and with regio and situ-selectivity. Initial competitive O- and C- complexation of the Lewis acid with Z-ligustilide promoted the formation of the dimers occurred in low yields and with regio and situ- selectivity. Initial competitive O- and C- complexation of the Lewis acid with Z-ligustilide promoted the formation of carbocations at C(8), C(6) and C(7), which were stabilized by the addition of the C(6')-C(7') olefin of a second unit of the starting material, to provide cations at C(6') and C(7'). Subsequent isomerizations and elimination of the catalyst afforded the dimeric products 9-12. The yields and structure of the products are quite dependent on variations of the reaction conditions and the catalyst employed.

  12. An ARHGEF10 deletion is highly associated with a juvenile-onset inherited polyneuropathy in Leonberger and Saint Bernard dogs.

    Full Text Available An inherited polyneuropathy (PN observed in Leonberger dogs has clinical similarities to a genetically heterogeneous group of peripheral neuropathies termed Charcot-Marie-Tooth (CMT disease in humans. The Leonberger disorder is a severe, juvenile-onset, chronic, progressive, and mixed PN, characterized by exercise intolerance, gait abnormalities and muscle atrophy of the pelvic limbs, as well as inspiratory stridor and dyspnea. We mapped a PN locus in Leonbergers to a 250 kb region on canine chromosome 16 (Praw = 1.16×10-10, Pgenome, corrected = 0.006 utilizing a high-density SNP array. Within this interval is the ARHGEF10 gene, a member of the rho family of GTPases known to be involved in neuronal growth and axonal migration, and implicated in human hypomyelination. ARHGEF10 sequencing identified a 10 bp deletion in affected dogs that removes four nucleotides from the 3'-end of exon 17 and six nucleotides from the 5'-end of intron 17 (c.1955_1958+6delCACGGTGAGC. This eliminates the 3'-splice junction of exon 17, creates an alternate splice site immediately downstream in which the processed mRNA contains a frame shift, and generates a premature stop codon predicted to truncate approximately 50% of the protein. Homozygosity for the deletion was highly associated with the severe juvenile-onset PN phenotype in both Leonberger and Saint Bernard dogs. The overall clinical picture of PN in these breeds, and the effects of sex and heterozygosity of the ARHGEF10 deletion, are less clear due to the likely presence of other forms of PN with variable ages of onset and severity of clinical signs. This is the first documented severe polyneuropathy associated with a mutation in ARHGEF10 in any species.

    Full Text Available This interview with the philosopher Bernard Stiegler was conducted in Paris on 28 January 2015, and first appeared in Dutch translation in the journal De uil van Minerva. The conversation begins by discussing the fundamental place occupied by the concept of ‘technics’ in Stiegler’s work, and how the ‘constitutivity’ of technics does and does not relate to Kant and Husserl. Stiegler is then asked about his relationship with Deleuze, and he responds by focusing on the concept of quasi-causality, but also by arguing that there is a certain trajectory in Deleuze’s thought, situating his own philosophy in relation to its various moments. Stiegler is then asked to respond to the Charlie Hebdo terrorist attacks carried out three weeks prior to the interview. After making a couple of precautionary remarks, Stiegler relates such occurrences to the problem of what he calls ‘spiritual poverty’, to the intensification of ‘negative sublimation’ that can occur when there is a disconnection between the generations, and more generally to the growth of nihilism. All of these phenomena relate to the exploitation of technology by a virulent capitalism that irrationally believes that only the market is rational. After consideration of the complex historical relationship between Islam and modernization, and of both of these to Nietzsche’s ‘death of God’, and after recalling the destructive role played by the West in the rise of fundamentalism and jihadism, Stiegler concludes by reflecting on the fact that, ultimately, ‘intellectuals’ have failed to use technologies in ways that produce alternatives to consumerism.

After consideration of the complex historical relationship between Islam and modernization, and of both of these to Nietzsche’s ‘death of God’, and after recalling the destructive role played by the West in the rise of fundamentalism and jihadism, Stiegler concludes by reflecting on the fact that, ultimately, ‘intellectuals’ have failed to use technologies in ways that produce alternatives to consumerism.

  15. Interim report on the National Bureau of Standards/Bureau of Radiological Health 60Co teletherapy survey

    International Nuclear Information System (INIS)

    Thompson, D.L.; Wyckoff, H.O.; Soares, C.G.

    1978-01-01

    During the past three years the National Bureau of Standards and the Bureau of Radiological Health have been conducting a survey of 60 Co teletherapy facilities to determine their accuracy in exposing a phantom to a prescribed dose. As of May 1977, some 700 units were surveyed of the approximately 1000 which are licensed to administer therapy in the United States. Preliminary data indicate that about two-thirds of the respondents were able to calculate the specified 300 rad dose within 5 rad, while 8% reported values which varied from the specified dose by more than 15 rad. The mean exposure determined for a set of dosimeters differed from the 300 rad value by less than 5% for 83% of units; 4% of the units produced an exposure which differed by more than 10% of the target value

    Reahard, Ross; Arguelles, Maria; Strong, Emma; Ewing, Michael; Kelly, Chelsey

    2012-01-01

    St. Bernard Parish, in southeast Louisiana, is rapidly losing coastal forests and wetlands due to a combination of natural and anthropogenic disturbances (e.g. subsidence, saltwater intrusion, low sedimentation, nutrient deficiency, herbivory, canal dredging, levee construction, spread of invasive species, etc.). After Hurricane Katrina severely impacted the area in 2005, multiple Non-Governmental Organizations (NGOs) have worked not only on rebuilding destroyed dwellings, but on rebuilding the ecosystems that once protected the citizens of St. Bernard Parish. Volunteer groups, NGOs, and government entities often work separately and independently of each other and use different sets of information to choose the best planting sites for coastal forests. Using NASA EOS, NRCS soil surveys, and ancillary road and canal data in conjunction with ground truthing, the team created maps of optimal planting sites for several species of wetland trees to aid in unifying these organizations, who share a common goal, under one plan. The methodology for this project created a comprehensive Geographic Information System (GIS) to help identify suitable planting sites in St. Bernard Parish. This included supplementing existing elevation data using LIDAR data and classifying existing land cover in the study area from ASTER multispectral satellite data. Low altitude AVIRIS hyperspectral imagery was used to assess the health of vegetation over an area near the intersection of the Mississippi River Gulf Outlet Canal (MRGO) and Bayou la Loutre. Historic extent of coastal forests was mapped using aerial photos from USGS collected between 1952 and 1956. The final products demonstrated the utility of combining NASA EOS with other geospatial data in assessing, monitoring, and restoring of coastal ecosystems in Louisiana. This methodology also provides a useful template for other ecological forecasting and coastal restoration applications.

    Loget, François

    2011-01-01

    Bernard Salignac and Lazare Schöner both published a treatise based on La Ramée's Algebra. Why did they endeavour to republish a book that their master had abandoned ? What changes did they make in the original ? They turned algebra into apedagogical discipline at a time when Ramism was making its presence felt in some Northern European educational establishments. Salignac took La Ramée's thoughts concerning the language of mathematics further and offered an original and precocious contribution to what I call the "scriptural turn" of mathematics at the end of the 16(th) century.

    Wereley, Ian Fraser

    This thesis investigates the interwar expressions of resistance to the use of oil by the British Royal Navy in the period 1927-1937. In particular, it examines the work of Captain Bernard Acworth and the South Wales Back to Coal Movement. It uses a critical geopolitics approach to analyse the ways in which the anti-oil critique framed the social, political, economic and military consequences of Britain's entry into the age of oil; the methods that were used by Acworth and the Back to Coal Movement to give voice to their dissent, and the reception given to their message by official and popular audiences.

    International Nuclear Information System (INIS)

    Anon.

    1996-01-01

    The completion of the Bureau Veritas (BV) company reorganization in France led to a stabilization of its main activities which fall into five engineering domains: sea service, building and exploitation safety, industry, international trade, aeronautics. The petroleum industry remains a great consumer of the offshore and onshore services provided by this company worldwide. This short paper briefly describes some recent contracts signed between BV and famous petroleum and service companies for the inspection and the safety analyses of industrial materials devoted to offshore exploitation, drilling and lodging, of gas transportation and storage systems (pipelines, reservoirs, tankers), and for the research and development studies related to deep-sea operations.

One of the conditions for the basic functions of the state is efficient administration headed by a person with the role of management. They not only hold the highest position, but also represent the authority of the state. For this reason, they need special protection. Each attack undermines the authority of the administration and trust in the state institutions. For the protection of persons performing managerial functions in the state corresponds to the Government Protection Bureau that providing them protection at the same time protect the state.

    Smithrick, John J.; Britton, Doris L.

    1993-01-01

    Individual pressure vessel (IPV) nickel-hydrogen technology was advanced at NASA Lewis and under Lewis contracts. Some of the advancements are as follows: to use 26 percent potassium hydroxide electrolyte to improve cycle life and performance, to modify the state of the art cell design to eliminate identified failure modes and further improve cycle life, and to develop a lightweight nickel electrode to reduce battery mass, hence reduce launch and/or increase satellite payload. A breakthrough in the LEO cycle life of individual pressure vessel nickel-hydrogen battery cells was reported. The cycle life of boiler plate cells containing 26 percent KOH electrolyte was about 40,000 accelerated LEO cycles at 80 percent DOD compared to 3,500 cycles for cells containing 31 percent KOH. Results of the boiler plate cell tests have been validated at NWSC, Crane, Indiana. Forty-eight ampere-hour flight cells containing 26 and 31 percent KOH have undergone real time LEO cycle life testing at an 80 percent DOD, 10 C. The three cells containing 26 percent KOH failed on the average at cycle 19,500. The three cells containing 31 percent KOH failed on the average at cycle 6,400. Validation testing of NASA Lewis 125 Ah advanced design IPV nickel-hydrogen flight cells is also being conducted at NWSC, Crane, Indiana under a NASA Lewis contract. This consists of characterization, storage, and cycle life testing. There was no capacity degradation after 52 days of storage with the cells in the discharged state, on open circuit, 0 C, and a hydrogen pressure of 14.5 psia. The catalyzed wall wick cells have been cycled for over 22,694 cycles with no cell failures in the continuing test. All three of the non-catalyzed wall wick cells failed (cycles 9,588; 13,900; and 20,575). Cycle life test results of the Fibrex nickel electrode has demonstrated the feasibility of an improved nickel electrode giving a higher specific energy nickel-hydrogen cell.

    The US Bureau of Mines, in cooperation with the Idaho National Engineering Laboratory (INEL), conducted over 30 hours of melting tests to vitrify simulated low-level radioactive wastes from the INEL. Radioactive Waste Management Complex (RWMC). Five separate waste compositions were investigated, each consisting of noncontaminated soil from the RWMC and surrogate materials used to simulate the actual buried wastes. The RWMC soil and five waste compositions were melted in a 50-lb, single-phase electric arc furnace with a water-cooled shell. These tests were conducted to determine melting parameters in preparation for a large-scale melting campaign to be conducted in the Bureau's 1-metric ton (mt), water-cooled-wall, 3-phase electric arc furnace. Bulk chemical composition was determined for each of the feed materials and for the slag, metal, fume solids, and offgas furnace products, and distributions were calculated for the key elements. The material balance for the furnace operation indicates that from 63 to 84 pct of the feed reported to the slag. Cerium, used as the surrogate for the radionuclides in the wastes, demonstrated an extremely strong affinity for the slag product. Although slag temperatures as low as 1,250 C were recorded when melting the RWMC soil, temperatures in excess of 1,600 C were necessary to achieve the fluidity required for a successful slag tap

    Denmark, Scott E; Chung, Won-Jin

    2008-06-20

    A catalytic system involving silicon tetrachloride and a chiral, Lewis basic bisphosphoramide catalyst is effective for the addition of glycolate-derived silyl ketene acetals to aldehydes. It was found that the sense of diastereoselectivity could be modulated by changing the size of the substituents on the silyl ketene acetals. In general, the trimethylsilyl ketene acetals derived from methyl glycolates with a large protecting group on the alpha-oxygen provide enantiomerically enriched alpha,beta-dihydroxy esters with high syn-diastereoselectivity, whereas the tert-butyldimethylsilyl ketene acetals derived from bulky esters of alpha-methoxyacetic acid provide enantiomerically enriched alpha,beta-dihydroxy esters with high anti-diastereoselecitvity.

    2017-08-14

    The aims of the study were to review recent advances in molecular imaging in the Lewy body dementias (LBD) and determine if these may support the clinical but contested temporal profile distinction between Parkinson disease (PD) with dementia (PDD) versus dementia with Lewy bodies (DLB). There do not appear to be major regional cerebral metabolic or neurotransmitter distinctions between PDD and DLB. However, recent studies highlight the relative discriminating roles of Alzheimer proteinopathies. PDD patients have lower cortical β-amyloid deposition than DLB. Preliminary tau PET studies suggest a gradient of increasing tau binding from cognitively normal PD (absent to lowest) to cognitively impaired PD (low) to DLB (intermediate) to Alzheimer disease (AD; highest). However, tau binding in DLB, including the medial temporal lobe, is substantially lower than in AD. Alzheimer-type proteinopathies appear to be more common in DLB compared to PDD with relative but no absolute differences. Given the spectrum of overlapping pathologies, future α-synuclein ligands are expected to have the best potential to distinguish the LBD from pure AD.

  8. Lewis Acid Assisted Nitrate Reduction with Biomimetic Molybdenum Oxotransferase Complex.

    Elrod, Lee Taylor; Kim, Eunsuk

    2018-03-05

    The reduction of nitrate (NO 3 - ) to nitrite (NO 2 - ) is of significant biological and environmental importance. While Mo IV (O) and Mo VI (O) 2 complexes that mimic the active site structure of nitrate reducing enzymes are prevalent, few of these model complexes can reduce nitrate to nitrite through oxygen atom transfer (OAT) chemistry. We present a novel strategy to induce nitrate reduction chemistry of a previously known catalyst Mo IV (O)(SN) 2 (2), where SN = bis(4- tert-butylphenyl)-2-pyridylmethanethiolate, that is otherwise incapable of achieving OAT with nitrate. Addition of nitrate with the Lewis acid Sc(OTf) 3 (OTf = trifluoromethanesulfonate) to 2 results in an immediate and clean conversion of 2 to Mo VI (O) 2 (SN) 2 (1). The Lewis acid additive further reacts with the OAT product, nitrite, to form N 2 O and O 2 . This work highlights the ability of Sc 3+ additives to expand the reactivity scope of an existing Mo IV (O) complex together with which Sc 3+ can convert nitrate to stable gaseous molecules.

    2012-03-01

    Few studies have examined connected speech in demented and non-demented patients with Parkinson's disease (PD). We assessed the speech production of 35 patients with Lewy body spectrum disorder (LBSD), including non-demented PD patients, patients with PD dementia (PDD), and patients with dementia with Lewy bodies (DLB), in a semi-structured narrative speech sample in order to characterize impairments of speech fluency and to determine the factors contributing to reduced speech fluency in these patients. Both demented and non-demented PD patients exhibited reduced speech fluency, characterized by reduced overall speech rate and long pauses between sentences. Reduced speech rate in LBSD correlated with measures of between-utterance pauses, executive functioning, and grammatical comprehension. Regression analyses related non-fluent speech, grammatical difficulty, and executive difficulty to atrophy in frontal brain regions. These findings indicate that multiple factors contribute to slowed speech in LBSD, and this is mediated in part by disease in frontal brain regions. Copyright © 2011 Elsevier Inc.

    2009-01-01

    Claude Bernard presented most of his fundamental results to the Société de Biologie, including proof of the modulation of the nervous system by the internal micromilieu. However, he did not describe the principle of a stable internal milieu as a condition for free life. Physiology, which is a part of biology, was not founded on cellular biology. Rather, Claude Bernard considered chemistry, anatomy and histology as the necessary auxiliary sciences for physiology. His articles are direct pictures, and not isolated ones, despite possible limitations, from a pre-montage movie of the physiological revolution he thought he had initiated, but not finished.

  15. Catalytic Conversion of Glucose into 5-Hydroxymethylfurfural by Hf(OTf4 Lewis Acid in Water

    Directory of Open Access Journals (Sweden)

    Junjie Li

    2015-12-01

    Full Text Available A series of Lewis acidic metal salts were used for glucose dehydration to 5-hydroymethylfurfural (HMF in water. Effect of valence state, ionic radii of Lewis acidic cation, and the type of anions on the catalytic performance have been studied systematically. The experimental results showed that the valence state played an important role in determining catalytic activity and selectivity. It was found that a higher glucose conversion rate and HMF selectivity could be obtained over high valent Lewis acid salts, where the ionic radii of these Lewis acidic metal salts are usually relatively small. Analysis on the effect of the anions of Lewis acid salts on the catalytic activity and the selectivity suggested that a higher glucose conversion and HMF selectivity could be readily obtained with Cl−. Furthermore, the recyclability of high valence state Lewis acid salt was also studied, however, inferior catalytic performance was observed. The deactivation mechanism was speculated to be the fact that high valence state Lewis acid salt was comparatively easier to undergo hydrolysis to yield complicated metal aqua ions with less catalytic activity. The Lewis acidic activity could be recovered by introducing a stoichiometric amount of hydrochloric acid (HCl to the catalytic before the reaction.

    "The Chronicles of Narnia" are a series of seven fairy tales written by C.S. Lewis that have become popular with both children and adults. Lewis points to five aspects of the fairy tale form that made the form suitable for expressing the images he saw. The aspects are: (1) no love interest; (2) no close psychology; (3) severe restraints…

    The Bureau of Reclamation is largest wholesaler of water in the United States. Located in the 17 western states, Reclamation serves water to 31 million people, provides irrigated water to 20 percent of Western farmers, and is the second largest producer of hydroelectric power in the United States. Through these activities, Reclamation generates large amounts of water and water-related data, describing reservoirs and river system conditions, hydropower, environmental compliance activities, infrastructure assets, and other aspects of Reclamation's mission activities. Reclamation aims to make water and water-related data sets more easily found, accessed, and used in decision-making activities in order to benefit the public, private sector, and research communities. Historically, there has not been an integrated, bureau-wide system to store data in machine-readable formats; nor a system to permit centralized browsing, open access, and web-services. Reclamation began addressing these limitations by developing the Reclamation Water Information System (RWIS), released in Spring 2017 (https://water.usbr.gov/). A bureau-wide team contributed to RWIS development, including water data stewards, database administrators, and information technology (IT) specialists. The first RWIS release publishes reservoir time series data from Reclamation's five regions and includes a map interface for sites identification, a query interface for data discovery and access, and web-services for automated retrieval. As RWIS enhancement continues, the development team is developing a companion system - the Reclamation Information Sharing Environment (RISE) - to provide access to the other data subjects and types (geospatial, documents). While RWIS and RISE are promising starts, Reclamation continues to face challenges in addressing open water data goals: making data consolidation and open publishing a value-added activity for programs that publish data locally, going beyond providing open access

    Streptococcal cell wall (SCW)-induced arthritis and adjuvant arthritis (AA) are rat models for chronic, erosive polyarthritis. Both models can be induced in susceptible Lewis rats, whereas F344 rats are resistant. In AA as well as in SCW arthritis, antigen-specific T lymphocytes have been demonstrated to be crucial for chronic disease. In this communication the authors describe their studies to probe the cellular mechanism responsible for the difference in susceptibility of Lewis and F344, using bone marrow chimeras. By transplanting bone marrow cells from F344 into lethally irradiated Lewis recipients, Lewis rats were rendered resistant to SCW arthritis induction. F344 rats reconstituted with Lewis bone marrow, i.e., Lewis----F344 chimeras, develop an arthritis upon SCW injection. For AA comparable results were obtained. These data suggest that both resistance and susceptibility to bacterium-induced chronic arthritis are mediated by hemopoietic/immune cells and that the recipiental environment does not influence the susceptibility to chronic joint inflammation

    High-quality perovskite films can be fabricated from Lewis acid-base adducts through molecule exchange. Substantial work is needed to fully understand the formation mechanism of the perovskite films, which helps to further improve their quality. Here, we study the formation of CH 3 NH 3 PbI 3 perovskite films by introducing some dimethylacetamide into the PbI 2 /N,N-dimethylformamide solution. We reveal that there are three key processes during the formation of perovskite films through the Lewis acid-base adduct approach: molecule intercalation of solvent into the PbI 2 lattice, molecule exchange between the solvent and CH 3 NH 3 I, and dissolution-recrystallization of the perovskite grains during annealing. The Lewis base solvents play multiple functions in the above processes. The properties of the solvent, including Lewis basicity and boiling point, play key roles in forming smooth perovskite films with large grains. We also provide some rules for choosing Lewis base additives to prepare high-quality perovskite films through the Lewis adduct approach.

  4. The thermoluminscent dosimetry service of the radiation protection bureau

    International Nuclear Information System (INIS)

    1978-12-01

    Thermoluminescent materials have been used in radiation dosimetry for many years, but their application to nationwide personnel dosimetry has been scarce. An undertaking of this nature requires that methods be established for identification of dosimeters and for fast interpretation and communication of dose to the users across the country. It is also necessary that records of cumulative dose of individual radiation workers be continuously updated, and such records be maintained for a prolonged period. To do this many problems pertinent to associated equpment, vis. the computer, TL reader, their interfacing, and to the operational procedures of the service had to be resolved. Since April 1977, the Radiation Protection Bureau has been providing a Thermoluminescent Dosimetry Service to Canadian radiation workers. This document describes the RPB dosimeter, its characteristics, various aspects of the service, objectives of the service, and how the objective goals of the service are achieved. (auth)

    Related to the effectiveness of decision-making by the management of travel bureau company, especially by managers, information serves frequent delays or incomplete. Although already computer-assisted, the existing application-based is used only handle one particular activity only, not integrated. This research is intended to produce an integrated information system that handles the overall operational activities of the company. By applying the object-oriented system development approach, the system is built with Visual Basic. Net programming language and MySQL database package. The result is a system that consists of 4 (four) separated program packages, including Reservation System, AR System, AP System and Accounting System. Based on the output, we can conclude that this system is able to produce integrated information that related to the problem of reservation, operational and financial those produce up-to-date information in order to support operational activities and decisionmaking process by related parties.

  7. Ransom, Religion, and Red Giants: C.S. Lewis and Fred Hoyle

    Science.gov (United States)

    Larsen, Kristine

    2010-01-01

    Famed fantasy writer C.S. Lewis (1898-1963) was known to friends as a well-read astronomy aficionado. However, this medieval scholar and Christian apologist embraced a pre-Copernican universe (with its astrological overtones) in his Chronicles of Narnia series and defended the beauty and relevance of the geocentric model in his final academic work, "The Discarded Image". In the "Ransom Trilogy” ("Out of the Silent Planet", "Perelandra", and "That Hideous Strength") philologist Ransom (loosely based on Lewis's close friend J.R.R. Tolkien) travels to Lewis's visions of Mars and Venus, where he interacts with intelligent extraterrestrials, battles with evil scientists, and aids in the continuation of extraterrestrial Christian values. In the final book, Ransom is joined by a handful of colleagues in open warfare against the satanic N.I.C.E. (National Institute for Coordinated Experiments). Geneticist and evolutionary biologist J.B.S. Haldane criticized Lewis for his scientifically inaccurate descriptions of the planets, and his disdain for the scientific establishment. Lewis responded to the criticism in essays of his own. Another of Lewis's favorite scientific targets was atheist Fred Hoyle, whom he openly criticized for anti-Christian statements in Hoyle's BBC radio series. Writer and Lewis friend Dorothy L. Sayers voiced her own criticism of Hoyle. In a letter, Lewis dismissed Hoyle as "not a great philosopher (and none of my scientific colleagues think much of him as a scientist.” Given Lewis's lack of respect for Hoyle, and use of creative license in describing the planets, and the flat-earth, "geocentric” Narnia, it is surprising that Lewis very carefully includes an astronomically correct description of red giants in two novels in the Narnia series ("The Magician's Nephew" and "The Last Battle"). This inclusion is even more curious given that Fred Hoyle is well-known as one of the pioneers in the field of stellar death and the properties of red giants.

    2013-01-01

    Catatonia, originally described by Karl Kahlbaum in 1874, may be regarded as a set of clinical features found in a subtype of schizophrenia, but the syndrome may also stem from organic causes including vascular parkinsonism, brain masses, globus pallidus lesions, metabolic derangements, and pharmacologic agents, especially first generation antipsychotics. Catatonia may include paratonia, waxy flexibility (cerea flexibilitas), stupor, mutism, echolalia, and catalepsy (abnormal posturing). A case of catatonia as a result of acute renal failure in a patient with dementia with Lewy bodies is described. This patient recovered after intravenous fluid administration and reinstitution of the atypical dopamine receptor blocking agent quetiapine, but benzodiazepines and amantadine are additional possible treatments. Recognition of organic causes of catatonia leads to timely treatment and resolution of the syndrome. PMID:23466522

  14. Survey on Cosmogenic 26Al in Lewis Cliff Meteorites

    1992-07-01

    INTRODUCTION: We have embarked upon a ^26Al gamma-ray survey of meteorites selected from about 2000 samples recently recovered from the Lewis Cliff Ice Fields (84 degrees 18'S/161 degrees 20'E). Due to its 705-ka half-life ^26Al can be used for estimating terrestrial ages and thus contribute to further characterization of Antarctic meteorites in addition to their classification and thermoluminescence (TL) properties. The ^26Al survey is also useful for identifying meteorites with unusual exposure histories, which merit additional measurements of cosmogenic radionuclides (by AMS) and noble gases. In addition, it provides clues on possible pairings. METHOD: Low-level gamma-ray spectroscopy is well suited for ^26Al survey work, since bulk meteorite samples can be measured routinely and nondestructively without any previous sample preparation. The required size of the samples (30-500 g) makes the method relatively independent of depth effects and compositional inhomogeneities. The use of a high-resolution GeLi detector also allows the determination of the natural ^40K activity and thus the K content of the samples, which can be used as an additional pairing criterion for ordinary chondrites. Also ^137Cs, a fall-out surface contamination [1], is simultaneously measured; low values may be characteristic for meteorites recently fallen or released from the ablating ice. For the detector an efficiency calibration curve has been made that adequately accounts for differences in size and shape of the meteorite samples. RESULTS and DISCUSSION: TERRESTRIAL AGES: So far, we have measured over 30 Lewis Cliff equilibrated H and L chondrites, collected from widely differing locations. Normalized to L-chondrite composition, the ^26Al contents range from 27 to 110 dpm/kg with peaks around 43 and 53 dpm/kg. This bimodal ^26Al distribution is reminiscent of that observed for Allan Hills ordinary chondrites [2]. Tentative terrestrial ages, calculated on the basis of ^26Al saturation

    1995-01-01

    The new transport property data that will be used in the NASA Lewis Research Center's Chemical Equilibrium and Applications Program (CEA) is presented. It complements a previous publication that documented the thermodynamic and transport property data then in use. Sources of the data and a brief description of the method by which the data were obtained are given. Coefficients to calculate the viscosity, thermal conductivity, and binary interactions are given for either one, or usually, two temperature intervals, typically 300 to 1000 K and 1000 to 5000 K. The form of the transport equation is the same as used previously. The number of species was reduced from the previous database. Many species for which the data were estimated were eliminated from the database. Some ionneutral interactions were added.

  16. A comparison of two instructional methods for drawing Lewis Structures

    Science.gov (United States)

    Terhune, Kari

    Two instructional methods for teaching Lewis structures were compared -- the Direct Octet Rule Method (DORM) and the Commonly Accepted Method (CAM). The DORM gives the number of bonds and the number of nonbonding electrons immediately, while the CAM involves moving electron pairs from nonbonding to bonding electrons, if necessary. The research question was as follows: Will high school chemistry students draw more accurate Lewis structures using the DORM or the CAM? Students in Regular Chemistry 1 (N = 23), Honors Chemistry 1 (N = 51) and Chemistry 2 (N = 15) at an urban high school were the study participants. An identical pretest and posttest was given before and after instruction. Students were given instruction with either the DORM (N = 45), the treatment method, or the CAM (N = 44), the control for two days. After the posttest, 15 students were interviewed, using a semistructured interview process. The pretest/posttest consisted of 23 numerical response questions and 2 to 6 free response questions that were graded using a rubric. A two-way ANOVA showed a significant interaction effect between the groups and the methods, F (1, 70) = 10.960, p = 0.001. Post hoc comparisons using the Bonferroni pairwise comparison showed that Reg Chem 1 students demonstrated larger gain scores when they had been taught the CAM (Mean difference = 3.275, SE = 1.324, p Chemistry 1 students performed better with the DORM, perhaps due to better math skills, enhanced working memory, and better metacognitive skills. Regular Chemistry 1 students performed better with the CAM, perhaps because it is more visual. Teachers may want to use the CAM or a direct-pairing method to introduce the topic and use the DORM in advanced classes when a correct structure is needed quickly.

    1990-09-01

    This report contains a set of recommendations prepared by Oak Ridge National Laboratory (ORNL) for the US Bureau of the Census pertaining to technology innovation and management. Technology has the potential to benefit the Bureau's data collection, capture, processing, and analysis activities. The entire Bureau was represented from Decennial Census to Economic Programs and various levels of Bureau management and numerous experts in technology. Throughout the Bureau, workstations, minicomputers, and microcomputers have found their place along side the Bureau's mainframes. The Bureau's new computer file structure called the Topologically Integrated Geographic Encoding and Referencing data base (TIGER) represents a major innovation in geographic information systems and impressive progress has been made with Computer Assisted Telephone Interviewing (CATI). Other innovations, such as SPRING, which aims to provide Bureau demographic analysts with the capability of interactive data analysis on minicomputers, are in the initial stages of development. Recommendations fall into five independent, but mutually beneficial categories. (1) The ADP Steering Committee be disbanded and replaced with The Technology Forum. (2) Establishment of a Technology Review Committee (TRC), to be composed of technology experts from outside the Bureau. (3) Designate technological gurus. These individuals will be the Bureau's experts in new and innovative technologies. (4) Adopt a technology innovation process. (5) Establish an Advanced Technology Studies Staff (ATSS) to promote technology transfer, obtain funding for technological innovation, manage innovation projects unable to find a home in other divisions, evaluate innovations that cut across Bureau organizational boundaries, and provide input into Bureau technology analyses.

  1. Lewis pair polymerization by classical and frustrated Lewis pairs: Acid, base and monomer scope and polymerization mechanism

    KAUST Repository

    Zhang, Yuetao

    2012-01-01

    Classical and frustrated Lewis pairs (LPs) of the strong Lewis acid (LA) Al(C 6F 5) 3 with several Lewis base (LB) classes have been found to exhibit exceptional activity in the Lewis pair polymerization (LPP) of conjugated polar alkenes such as methyl methacrylate (MMA) as well as renewable α-methylene-γ-butyrolactone (MBL) and γ-methyl- α-methylene-γ-butyrolactone (γ-MMBL), leading to high molecular weight polymers, often with narrow molecular weight distributions. This study has investigated a large number of LPs, consisting of 11 LAs as well as 10 achiral and 4 chiral LBs, for LPP of 12 monomers of several different types. Although some more common LAs can also be utilized for LPP, Al(C 6F 5) 3-based LPs are far more active and effective than other LA-based LPs. On the other hand, several classes of LBs, when paired with Al(C 6F 5) 3, can render highly active and effective LPP of MMA and γ-MMBL; such LBs include phosphines (e.g., P tBu 3), chiral chelating diphosphines, N-heterocyclic carbenes (NHCs), and phosphazene superbases (e.g., P 4- tBu). The P 4- tBu/Al(C 6F 5) 3 pair exhibits the highest activity of the LP series, with a remarkably high turn-over frequency of 9.6 × 10 4 h -1 (0.125 mol% catalyst, 100% MMA conversion in 30 s, M n = 2.12 × 10 5 g mol -1, PDI = 1.34). The polymers produced by LPs at RT are typically atactic (P γMMBL with ∼47% mr) or syndio-rich (PMMA with ∼70-75% rr), but highly syndiotactic PMMA with rr ∼91% can be produced by chiral or achiral LPs at -78 °C. Mechanistic studies have identified and structurally characterized zwitterionic phosphonium and imidazolium enolaluminates as the active species of the current LPP system, which are formed by the reaction of the monomer·Al(C 6F 5) 3 adduct with P tBu 3 and NHC bases, respectively. Kinetic studies have revealed that the MMA polymerization by the tBu 3P/ Al(C 6F 5) 3 pair is zero-order in monomer concentration after an initial induction period, and the polymerization

    The U-Pb age of a meta-granophyre from the Val de Rhemes (Brianconnais basement of the Aosta valley) of 511{+-}9 Ma suggests that the micaschists which dominate the pre-alpine basement of the Grand-Saint-Bernard Nappe are, in part, of Early Paleozoic age. The Brianconnais domain is characterized by a Cambrian to Ordovician alkalineto sub-alkaline (monzonitic) magmatism, similar in age to orthogneisses known in other parts of the Variscan belt and generally interpreted as related to an extensional event.

    2016-06-01

    Full Text Available Der Artikel untersucht die narrativen Parallelen zwischen roman courtois und phantastischem Thriller anhand von Bernard Leonettis „polar arthurien“ La Quête brestoise. Dabei rückt das Hauptmotiv der (Grals-Queste in den Vordergrund, das im mittelalterlichen Roman als ritterliche aventure und im Kriminalroman als actiongeladene Suche jeweils den strukturgebenden Handlungsrahmen darstellt und aufgrund des Kontrasts zwischen der früheren Lebenswelt des Protagonisten Chevalier und dem modernen Brest zahlreiche parodistische Züge erhält. Eine wichtige Rolle in der Analyse spielt ferner die Raum-Zeit-Struktur, die mit Bachtin als wunderbare Welt, in der die Zeit des Abenteuers vorherrscht, beschrieben werden kann und demnach derjenigen des höfischen Romans ähnelt: Beim letzten Gefecht, welches auf einer Yacht ausgetragen wird, die im Inneren eine Steingrotte birgt, scheint die Zeit stillzustehen und eigenen – phantastischen – Gesetzen zu unterliegen.

  4. Lower Lip Reconstruction after Wide Excision of a Malignancy with Barrel-Shaped Excision or the Webster Modification of the Bernard Operation

    Full Text Available BackgroundBecause there are numerous methods for reconstruction of the lower lip, it is not easy to choose the optimal method. In choosing the surgical method for lower lip reconstruction, we obtained acceptable outcomes based on our treatment strategy, which included either a barrel-shaped excision or the Webster modification of the Bernard operation. We report on the surgical outcomes based on our treatment strategy.MethodsThis study included 26 patients who underwent lower lip reconstructive surgery from September 1996 to September 2010. The operation was done using either a barrel-shaped excision or the Webster modification, considering the location of the defect, the size of the defect, and the amount of residual tissue on the lateral side of the vermilion after excision.ResultsIn our series, 3 patients underwent a single barrel-shaped excision, and nine patients underwent a double barrel-shaped excision. In addition, the unilateral Webster modification was performed on in 6 patients, and there were eight cases of bilateral Webster modification. All of the patients except one were satisfied with the postoperative shape of the lip. In one case both recurrence and dehiscence occurred. One patient had a good postoperative lip shape, but had difficulty wearing a denture, and also underwent commissuroplasty. Furthermore, there were two patients who complained of drooling, and 4 with paresthesia.ConclusionsA soft tissue defect resulting from wide excision of a lower lip malignancy can be successfully reconstructed using only one of two surgical methods: the barrel-shaped excision or the Webster modification of the Bernard operation.

    This article explores the work by Bernard Katz (1911-2003), Stephen W. Kuffler (1913-1980), and John C. Eccles (1903-1997) on the nerve-muscle junction as a milestone in twentieth-century neurophysiology with wider scientific implications. The historical question is approached from two perspectives: (a) an investigation of twentieth-century solutions to a longer physiological dispute and (b) an examination of a new kind of laboratory and academic cooperation. From this vantage point, the work pursued in Sydney by Sir John Carew Eccles' team on the neuromuscular junction is particularly valuable, since it contributed a central functional element to modern physiological understanding regarding the function and structure of the human and animal nervous system. The reflex model of neuromuscular action had already been advanced by neuroanatomists such as Georg Prochaska (1749-1820) in Bohemia since the eighteenth century. It became a major component of neurophysiological theories during the nineteenth century, based on the law associated with the names of François Magendie (1783-1855) in France and Charles Bell (1774-1842) in Britain regarding the functional differences of the sensory and motor spinal nerves. Yet, it was not until the beginning of the twentieth century that both the histological and the neurophysiological understanding of the nerve-muscle connection became entirely understood and the chemical versus electrical transmission further elicited as the mechanisms of inhibition. John C. Eccles, Bernard Katz, and Stephen W. Kuffler helped to provide some of the missing links for modern neurophysiology. The current article explores several of their scientific contributions and investigates how the context of forced migration contributed to these interactions in contingently new ways.

    The concept of green chemistry began in the USA in the 1990s. Since the publication of the 12 principles of this concept, many reactions in organic chemistry have been developed, and chemical products have been synthesized under environmentally friendly conditions. Lewis acid mediated synthetic transformations are by far the most numerous and best studied. However, the use of certain Lewis acids may cause risks to environmental and human health. This Review discusses the evolution of Lewis acid catalyzed reactions from a homogeneous liquid phase to the solid phase to yield the expected organic molecules under green, safe conditions. In particular, recent developments and applications of biosourced catalysts from plants are highlighted. © 2018 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.

    Gilbert, L. J.; Triezenberg, D. M.

    1979-01-01

    A NASA-Lewis program to study the anticipated performance of a wind turbine generator farm on an electric utility network is surveyed. The paper describes the approach of the Lewis Wind Energy Project Office to developing analysis capabilities in the area of wind turbine generator-utility network computer simulations. Attention is given to areas such as, the Lewis Purdue hybrid simulation, an independent stability study, DOE multiunit plant study, and the WEST simulator. Also covered are the Lewis mod-2 simulation including analog simulation of a two wind turbine system and comparison with Boeing simulation results, and gust response of a two machine model. Finally future work to be done is noted and it is concluded that the study shows little interaction between the generators and between the generators and the bus.

  8. Barack Obama, John Lewis, and the Legacy of the Civil Rights Struggle

    Full Text Available The watershed election in 2008 of Barack Obama as the first President of the United States to have African ancestry resulted from the life work of such civil rights activists as U.S. Congressman John Lewis. Born on a sharecropper’s farm in 1940, the African American Lewis grew up in segregated Alabama. As a college student in Nashville, he joined the sit-in protests and volunteered for the original Freedom Ride in 1961. He was elected chairman of the Student Nonviolent Coordinating Committee, becoming the youngest speaker at the March on Washington in 1963. The radical shift to Black ultimately forced Lewis out of SNCC. Consequently Lewis capitalized on the Voting Rights Act of 1965, turned his attentions to voter registration campaigns, and continued working within the system. In 1986 he won election to the U.S. House of Representatives to represent Atlanta’s Fifth Congressional District, a seat he continues to hold today.

    Kenny, Eva R; Blamire, Andrew M; Firbank, Michael J; O'Brien, John T

    2012-02-01

    Using resting-state functional magnetic resonance imaging, spontaneous low-frequency fluctuations in the blood oxygenation level-dependent signal were measured to investigate connectivity between key brain regions hypothesized to be differentially affected in dementia with Lewy bodies compared with Alzheimer's disease and healthy controls. These included connections of the hippocampus, because of its role in learning, and parietal and occipital areas involved in memory, attention and visual processing. Connectivity was investigated in 47 subjects aged 60 years and over: 15 subjects with dementia with Lewy bodies, 16 subjects with Alzheimer's disease and 16 control subjects. Subjects were scanned using a 3 Tesla magnetic resonance imaging system. The mean blood oxygenation level-dependent signal time series was extracted from seed regions in the hippocampus, posterior cingulate cortex, precuneus and primary visual cortex and correlated with all other brain voxels to determine functional connectivity. Both subjects with dementia with Lewy bodies and Alzheimer's disease showed greater connectivity than control subjects. Compared with controls, the dementia with Lewy bodies group had greater connectivity between the right posterior cingulate cortex and other brain areas. In dementia with Lewy bodies, there were no significant differences in hippocampal connectivity compared with controls, but in Alzheimer's disease left hippocampal connectivity was greater compared with controls. There were no significant differences between groups for precuneus or primary visual cortex connectivity. No seed regions showed significantly less connectivity in subjects with dementia with Lewy bodies or Alzheimer's disease compared with controls. We found greater connectivity with the posterior cingulate in dementia with Lewy bodies and with the hippocampus in Alzheimer's disease. Consistent with the known relative preservation of memory in dementia with Lewy bodies compared with Alzheimer

    Amyloid deposition is common in dementia with Lewy bodies, but its pathophysiological significance is unclear. The objective of this study was to investigate the relationship between amyloid deposition and clinical profile, gray matter volume, and brain perfusion in dementia with Lewy bodies. Dementia with Lewy bodies (n = 37), Alzheimer's disease (n = 20), and controls (n = 20) underwent a thorough clinical assessment, 3T MRI, and early- and late-phase 18 F-Florbetapir PET-CT to assess cortical perfusion and amyloid deposition, respectively. Amyloid scans were visually categorized as positive or negative. Image analysis was carried out using statistical parametric mapping (SPM) 8. There were no significant differences between amyloid-positive and amyloid-negative dementia with Lewy bodies cases in age (P = .78), overall cognitive impairment (P = .83), level of functional impairment (P = .80), or any other clinical or cognitive scale. There were also no significant differences in hippocampal or gray matter volumes. However, amyloid-positive dementia with Lewy bodies cases had lower medial temporal lobe perfusion (P = .03) than amyloid-negative cases, although a combination of medial temporal lobe perfusion, hippocampal volume, and cognitive measures was unable to accurately predict amyloid status in dementia with Lewy bodies. Amyloid deposition was not associated with differences in clinical or neuropsychological profiles in dementia with Lewy bodies, but was associated with imaging evidence of medial temporal lobe dysfunction. The presence of amyloid in dementia with Lewy bodies cannot be identified on the basis of clinical and other imaging features and will require direct assessment via PET imaging or CSF. © 2018 The Authors.

    2013-07-24

    A dual activation strategy integrating N-heterocyclic carbene (NHC) catalysis and a second Lewis base has been developed. NHC-bound homoenolate equivalents derived from α,β-unsaturated aldehydes combine with transient reactive o-quinone methides in an enantioselective formal [4 + 3] fashion to access 2-benzoxopinones. The overall approach provides a general blueprint for the integration of carbene catalysis with additional Lewis base activation modes.

    2009-02-01

    This study explores the transformation of trichloroethene (TCE) caused by heating contaminated soil and groundwater samples obtained from the East Gate Disposal Yard (EGDY) located in Fort Lewis, WA. After field samples transferring into glass ampules and introducing 1.5 micromol of TCE, the sealed ampules were incubated at temperatures of 25, 50, and 95 degrees C for periods of up to 95.5 days. Although TCE was completely transformed into cis-1,2-dichloroethene (cis-DCE) after 42 days at 25 degrees C by microbial activity, this transformation was not observed at 50 or 95 degrees C. Chloride levels increased after 42 days at 25 degrees C corresponding to the mass of TCE transformed to cis-DCE, were constant at 50 degrees C, and increased at 95 degrees C yielding a TCE degradation half-life of 1.6-1.9 years. These findings indicate that indigenous microbes contribute to the partial dechlorination of TCE to cis-DCE at temperatures of less than 50 degrees C, whereas interphase mass transfer and physical recovery of TCE will predominate over in situ degradation processes at temperatures of greater than 50 degrees C during thermal treatment at the EGDY site.

    The NASA Lewis heat pipe code has been developed to predict the performance of heat pipes in the steady state. The code can be used as a design tool on a personal computer or, with a suitable calling routine, as a subroutine for a mainframe radiator code. A variety of wick structures, including a user input option, can be used. Heat pipes with multiple evaporators, condensers, and adiabatic sections in series and with wick structures that differ among sections can be modeled. Several working fluids can be chosen, including potassium, sodium, and lithium, for which the monomer-dimer equilibrium is considered. The code incorporates a vapor flow algorithm that treats compressibility and axially varying heat input. This code facilitates the determination of heat pipe operating temperatures and heat pipe limits that may be encountered at the specified heat input and environment temperature. Data are input to the computer through a user-interactive input subroutine. Output, such as liquid and vapor pressures and temperatures, is printed at equally spaced axial positions along the pipe as determined by the user

  8. Lewis Swift celebrated comet hunter and the people's astronomer

    2017-01-01

    This biography covers the life of Lewis Swift (1820-1913), who discovered 13 comets and nearly 1,200 other deep sky objects. All 13 comets found by Swift now bear his name, including three periodic comets with periods of 6 years (11P/Tempel-Swift-LINEAR), 9 years (64P/Swift-Gehrels), and 133 years (109P/Swift-Tuttle). Swift's enthusiasm and success as an amateur astronomer helped make him famous in the United States. With the help of others, Swift was able to buy a 16-inch refractor, the third largest telescope in the United States at the time. Hulbert Harrington Warner built "Warner Observatory" to house this telescope. As a prolific writer and lecturer, Swift's stories appeared in newspapers and magazines, while his lectures showed that he was able to explain anything in a way that everyone could understand.  When Warner went broke during the "Panic of 1893," Swift was forced to leave his home. Almost two dozen invitations arrived from around the United States asking him to bring his telescope to their ci...

    2002-01-01

    Dementia with lewy bodies (DLB) is the second common degenerative dementia and has several characteristics including fluctuating cognition, visual hallucination and Parkinsonism. We investigated clinical manifestations and neuroimaging findings in DLB patients. Ten probable DLB patients were included in this study. Brain MRI, Tc-99m HMPAO brain perfusion SPECT and I-123 IPT SPECT were performed. All patients were men and mean age of onset was 64.2 years (range from 54 to 80). All had fluctuating cognition and Parkinsonism, and 8 had visual hallucination. Dementia preceded Parkinsonism in 3 patients. Fluctuation of K-MMSE ranges from 3 to 8 points. Rest tremor was seen in 5 patients. Brain MRI showed cortical atrophy in all patients. Tc-99m brain perfusion SPECT showed hypoperfusion in occipital area as well as fronto-temporo-parietal areas. I-123 IPT SPECT revealed reduced uptake comparable to Parkinson's disease in the striatum. DLB should be first considered as one of possible diagnosis in patients showing dementia in the early stage of Parkinsonism. Hypoperfusion in the occipital area was thought to be a characteristic finding in DLB and to be helpful in differentiating DLB from other degenerative dementias

  10. Microfluidic Separation of Ethylene and Ethane Using Frustrated Lewis Pairs.

    2015-12-21

    Separation of gaseous olefins and paraffins is one of the most important separation processes in the industry. Development of new cost-effective technologies aims at reducing the high energy consumption during the separation process. Here, we took advantage of the reaction of frustrated Lewis pairs (FLPs) with ethylene to achieve reactive extraction of ethylene from ethylene-ethane mixtures. The extraction was studied using a microfluidic platform, which enabled a rapid, high-throughput assessment of reaction conditions to optimize gas separation efficiency. A separation factor of 7.3 was achieved for ethylene from a 1:1 volume ratio mixture of ethylene and ethane, which corresponded to an extracted ethylene purity of 88 %. The results obtained in the microfluidic studies were validated using infrared spectroscopy. This work paves the way for further development of the FLPs and optimization of reaction conditions, thereby maximizing the separation efficiency of olefins from their mixtures with paraffins. © 2015 WILEY-VCH Verlag GmbH & Co.

  11. Streamline segment statistics of premixed flames with nonunity Lewis numbers

    Chakraborty, Nilanjan; Wang, Lipo; Klein, Markus

    2014-03-01

    The interaction of flame and surrounding fluid motion is of central importance in the fundamental understanding of turbulent combustion. It is demonstrated here that this interaction can be represented using streamline segment analysis, which was previously applied in nonreactive turbulence. The present work focuses on the effects of the global Lewis number (Le) on streamline segment statistics in premixed flames in the thin-reaction-zones regime. A direct numerical simulation database of freely propagating thin-reaction-zones regime flames with Le ranging from 0.34 to 1.2 is used to demonstrate that Le has significant influences on the characteristic features of the streamline segment, such as the curve length, the difference in the velocity magnitude at two extremal points, and their correlations with the local flame curvature. The strengthenings of the dilatation rate, flame normal acceleration, and flame-generated turbulence with decreasing Le are principally responsible for these observed effects. An expression for the probability density function (pdf) of the streamline segment length, originally developed for nonreacting turbulent flows, captures the qualitative behavior for turbulent premixed flames in the thin-reaction-zones regime for a wide range of Le values. The joint pdfs between the streamline length and the difference in the velocity magnitude at two extremal points for both unweighted and density-weighted velocity vectors are analyzed and compared. Detailed explanations are provided for the observed differences in the topological behaviors of the streamline segment in response to the global Le.

    2015-06-22

    The catalytic performance of homogeneous Lewis acid catalysts and their interaction with Ru/C catalyst are studied in the catalytic transfer hydrogenation of furfural by using 2-propanol as a solvent and hydrogen donor. We find that Lewis acid catalysts hydrogenate the furfural to furfuryl alcohol, which is then etherified with 2-propanol. The catalytic activity is correlated with an empirical scale of Lewis acid strength and exhibits a volcano behavior. Lanthanides are the most active, with DyCl3 giving complete furfural conversion and a 97 % yield of furfuryl alcohol at 180 °C after 3 h. The combination of Lewis acid and Ru/C catalysts results in synergy for the stronger Lewis acid catalysts, with a significant increase in the furfural conversion and methyl furan yield. Optimum results are obtained by using Ru/C combined with VCl3 , AlCl3 , SnCl4 , YbCl3 , and RuCl3 . Our results indicate that the combination of Lewis acid/metal catalysts is a general strategy for performing tandem reactions in the upgrade of furans. © 2015 WILEY-VCH Verlag GmbH & Co.

    Inflammation generates changes in the protein constituents of the aqueous humor. Proteins that change in multiple models of uveitis may be good biomarkers of disease or targets for therapeutic intervention. The present study was conducted to identify differentially-expressed proteins in the inflamed aqueous humor. Two models of uveitis were induced in Lewis rats: experimental autoimmune uveitis (EAU) and primed mycobacterial uveitis (PMU). Differential gel electrophoresis was used to compare naïve and inflamed aqueous humor. Differentially-expressed proteins were separated by using 2-D gel electrophoresis and excised for identification with matrix-assisted laser desorption/ionization-time of flight (MALDI-TOF). Expression of select proteins was verified by Western blot analysis in both the aqueous and vitreous. The inflamed aqueous from both models demonstrated an increase in total protein concentration when compared to naïve aqueous. Calprotectin, a heterodimer of S100A8 and S100A9, was increased in the aqueous in both PMU and EAU. In the vitreous, S100A8 and S100A9 were preferentially elevated in PMU. Apolipoprotein E was elevated in the aqueous of both uveitis models but was preferentially elevated in EAU. Beta-B2-crystallin levels decreased in the aqueous and vitreous of EAU but not PMU. The proinflammatory molecules S100A8 and S100A9 were elevated in both models of uveitis but may play a more significant role in PMU than EAU. The neuroprotective protein β-B2-crystallin was found to decline in EAU. Therapies to modulate these proteins in vivo may be good targets in the treatment of ocular inflammation.

  15. Improved lignin polyurethane properties with Lewis acid treatment.

    Chung, Hoyong; Washburn, Newell R

    2012-06-27

    Chemical modification strategies to improve the mechanical properties of lignin-based polyurethanes are presented. We hypothesized that treatment of lignin with Lewis acids would increase the concentration of hydroxyl groups available to react with diisocyanate monomers. Under the conditions used, hydrogen bromide-catalyzed modification resulted in a 28% increase in hydroxyl group content. Associated increases in hydrophilicity of solvent-cast thin films were also recorded as evidenced by decreases in water contact angle. Polyurethanes were then prepared by first preparing a prepolymer based on mixtures of toluene-2,4-diisocyanate (TDI) and unmodified or modified lignin, then polymerization was completed through addition of polyethylene glycol (PEG), resulting in mass ratios of TDI:lignin:PEG of 43:17:40 in the compositions investigated here. The mixture of TDI and unmodified lignin resulted in a lignin powder at the bottom of the liquid, suggesting it did not react directly with TDI. However, a homogeneous solution resulted when TDI and the hydrogen bromide-treated lignin were mixed, suggesting demethylation indeed increased reactivity and resulted in better integration of lignin into the urethane network. Significant improvements in mechanical properties of modified lignin polyurethanes were observed, with a 6.5-fold increase in modulus, which were attributed to better integration of the modified lignin into the covalent polymer network due to the higher concentration of hydroxyl groups. This research indicates that chemical modification strategies can lead to significant improvements in the properties of lignin-based polymeric materials using a higher fraction of an inexpensive lignin monomer from renewable resources and a lower fraction an expensive, petroleum-derived isocyanate monomer to achieve the required material properties.

    Purpose: This study aimed to transfer the hPNAS-4 gene, a novel apoptosis-related human gene, into Lewis lung cancer (LL2) and observe its radiosensitive effect on radiation therapy in vitro and in vivo. Methods and Materials: The hPNAS-4 gene was transfected into LL2 cells, and its expression was detected via western blot. Colony formation assay and flow cytometry were used to detect the growth and apoptosis of cells treated with irradiation/PNAS-4 in vitro. The hPNAS-4 gene was transferred into LL2-bearing mice through tail vein injection of the liposome/gene complex. The tumor volumes were recorded after radiation therapy. Proliferating cell nuclear antigen (PCNA) immunohistochemistry staining and terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) assay were performed to detect the tumor cell growth and apoptosis in vivo. Results: The hPNAS-4 gene was successfully transferred into LL2 cells and tumor tissue, and its overexpressions were confirmed via western blot analysis. Compared with the control, empty plasmid, hPNAS-4, radiation, and empty plasmid plus radiation groups, the hPNAS-4 plus radiation group more significantly inhibited growth and enhanced apoptosis of LL2 cells in vitro and in vivo (P<.05). Conclusions: The hPNAS-4 gene was successfully transferred into LL2 cells and tumor tissue and was expressed in both LL2 cell and tumor tissue. The hPNAS-4 gene therapy significantly enhanced growth inhibition and apoptosis of LL2 tumor cells by radiation therapy in vitro and in vivo. Therefore, it may be a potential radiosensitive treatment of radiation therapy for lung cancer.

  17. Lewis M. Rutherfurd and the First Photograph of Solar Granulation

    A major astronomical controversy of the mid-19th century was discordant descriptions of the small scale structure of the solar surface. Visual observers contradicted each other by describing the surface as consisting of “corrugations”, “willow leaves”, “rice grains”, “cumuli”, “thatch”, “granules”, etc. Early photographs of the solar surface were not good enough to settle the controversy. The French astronomer Jules Janssen is credited with the first 1876 photographs that clearly showed what we now call solar granulation (1876, CRAS 82, 1363). Upon seeing these images, New Yorker Lewis M. Rutherfurd (1878, MNRAS 38, 410) praised the high quality of Janssen’s images but asserted that he had also photographed granulation as early as 1871 using collodion wet plates. He sent copies of his best photograph to the Royal Astronomical Society to support his assertion. Curious about his claim, Briggs and Harvey set up Rutherfurd’s 13-inch achromatic refractor on Kitt Peak and found that it easily showed well-resolved solar granulation, so his claim might well have been justified. But without his plates we could not confirm the claim. For 140 years the copies of Rutherfurd’s best solar photograph remained in the archives of the Royal Astronomical Society and were recently discovered by Prosser (RAS Photographs A3/001B and A3/002). By coincidence a few days later, Briggs found the original August 11, 1871 plate. Despite poor condition these photographs show solar granulation. There are at least two other possible early claimants (Reade; Vogel) but their plates are almost certainly lost. Rutherfurd was a master of astronomical instrumentation and photography. He was reticent about his work, letting results speak for themselves, so it is satisfying to find that he was justified in making his claim of priority.

  18. Manipulating the Lewis antigen specificity of the cholesterol-dependent cytolysin lectinolysin

    Full Text Available The cholesterol-dependent cytolysins (CDCs attack cells by punching large holes in their membranes. Lectinolysin from Streptococcus mitis is unique among CDCs due to the presence of an N-terminal lectin domain that enhances the pore-forming activity of the toxin. We recently determined the crystal structures of the lectin domain in complex with various glycans. These structures revealed the molecular basis for the Lewis antigen specificity of the toxin. Based on this information we have used in silico molecular modelling to design a mutant toxin, which we predicted would increase its specificity for Lewis y, an antigen found on the surface of cancer cells. Surprisingly, we found by surface plasmon resonance binding experiments that the resultant mutant lectin domain exhibited higher specificity for Lewis b antigens instead. We then undertook comparative crystallographic and molecular dynamics simulation studies of the wild-type and mutant lectin domains to understand the molecular basis for the disparity between the theoretical and experimental results. The crystallographic results revealed that the net number of interactions between Lewis y and wild-type versus mutant was unchanged whereas there was a loss of a hydrogen bond between mutant and Lewis b compared to wild-type. In contrast, the molecular dynamics studies revealed that the Lewis b antigen spent more time in the binding pocket of the mutant compared to wild-type and the reverse was true for Lewis y. The results of these simulation studies are consistent with the conclusions drawn from the surface plasmon resonance studies. This work is part of a program to engineer lectinolysin so that it will target and kill specific cells in human diseases.

    Full Text Available Three versions of Bartlett Lewis rectangular pulse rainfall models, namely, the Original Bartlett Lewis (OBL, Modified Bartlett Lewis (MBL, and 2N-cell-type Bartlett Lewis model (BL2n, are considered. These models are fitted to the hourly rainfall data from 1970 to 2008 obtained from Petaling Jaya rain gauge station, located in Peninsular Malaysia. The generalized method of moments is used to estimate the model parameters. Under this method, minimization of two different objective functions which involve different weight functions, one weight is inversely proportional to the variance and another one is inversely proportional to the mean squared, is carried out using Nelder-Mead optimization technique. For the purpose of comparison of the performance of the three different models, the results found for the months of July and November are used for illustration. This performance is assessed based on the goodness of fit of the models. In addition, the sensitivity of the parameter estimates to the choice of the objective function is also investigated. It is found that BL2n slightly outperforms OBL. However, the best model is the Modified Bartlett Lewis MBL, particularly when the objective function considered involves weight which is inversely proportional to the variance.

Available free on the MAA website at http://www.maa.org/ql/calcvscontext.htmlThe papers in Calculation vs. Context discuss the role of quantitative literacy in the K-12 curriculum and in teacher education. The papers present a varied set of perspectives and address three themes: the changing environment of education in American society; the challenges, and the necessity, of preparing teachers to teach quantitative literacy and of including quantitative literacy in the K-12 education; and cross-disciplinary approaches to quantitative literacy. While the conclusion reached by several of the authors is that the best place to teach quantitative literacy is at the college level, the book offers serious considerations of how quantitative literacy can and should inform the K-12 curriculum. The book also marks a turning point in the quantitative literacy movement as “QL explorers,” as Lynn Steen calls them, move beyond issues of definitions and content to a discussion of how to bring quantitative literacy into a broader setting.

    Full Text Available This article is the result of a research project funded by CNPq / CAPES period of 2013-2014, developed in a school serving students from elementary education II and high school. The project aims to understand aspects of the training of readers and writers in the elementary school, since it is concerned with the admission of students not literate in the sixth year. As part of the wider project developed a research project to understand how Bernard Charlot comprises a school, place of training of young people, since for him is in relation with the knowledge that ubjects participating in different modes of the process social reproduction signifying their school experience and transforming itself. Methodologically, the Lessons Collective Pedagogical Work with teachers and classes that involved working with reading and writing were audio recorded during the year 2013 so they could be analyzed. We also take as material for analysis electronic correspondence exchanged between teachers and researchers, as well as the materials posted on social networks of which we were part. In this paper, we question the subtle interface between assessments and large-scale production of school failure relating it to media fanfare. Points to resistance from educators to current accountability policies in education, which cross the pedagogical work "tying" the curriculum does not always mean a certain school communities to certain contents. It is noteworthy, in this process, the importance of collective work in lieu of the prescriptive official determinations.

    Full Text Available This paper presents research results regarding information accuracy in the Serbian credit bureau reports and tries to identify the reasons which affect the accuracy of the information presented in credit bureau reports, in global terms. The research was conducted by interviewing respondents. Comparative analysis was used in order to formulate proposal of factors which determine information accuracy in the credit bureau reports. The results show that the materially significant errors in information presented in Serbian credit bureau reports make 0.5% of the sample. This implies that creditors in Serbia base their credit decisions on reliable information. The results of this study were compared to results of the studies conducted in USA and Germany in order to formulate proposal of factors which influence the information accuracy in the credit bureau reports. In order toimprove information accuracy in credit bureau reports, in global terms, special attention should be paid to formulation of international standards of credit reporting and identification systems of natural persons and legal entities.

  3. Lewis-Acid/Base Effects on Gallium Volatility in Molten Chlorides

    Williams, D.F.

    2001-01-01

    It has been proposed that GaCl 3 can be removed by direct volatilization from a Pu-Ga alloy that is dissolved in a molten chloride salt. Although pure GaCl 3 is quite volatile (boiling point, 201 C), the behavior of GaCl 3 dissolved in chloride salts is different due to solution effects and is critically dependent on the composition of the solvent salt (i.e., its Lewis-acid/base character). In this report, the behavior of gallium in prototypical Lewis-acid and Lewis-base salts is compared. It was found that gallium volatility is suppressed in basic melts and enhanced in acidic melts. The implications of these results on the potential for simple gallium removal in molten salt systems are significant

    Cellulosic pulps have been successfully isolated from wheat straw through a Lewis acids organosolv treatment. The use of Lewis acids with different hardness produced pulps with different delignification degrees. The cellulosic residue was characterised by chemical composition, X-ray diffraction, FT-IR spectroscopy, N2 physisorption, scanning electron microscopy and potential for anaerobic digestibility. Surface area and pore volume increased with the hardness of the Lewis acid, in correspondence with the decrease of the amount of lignin and hemicellulose in the pulp. The non linearity of the correlation between porosity and composition suggests that an agglomeration of cellulose fibrils occurs in the early stages of pulping. All organosolv pulps presented a significantly higher methane potential than the parent straw. A methane evolution of 295Ncm(3)/g OM was reached by a moderate improvement of the accessibility of the native straw. Copyright © 2016 Elsevier Ltd. All rights reserved.

    This paper reports on the chromatographic properties of porous microparticulate zirconium oxide surfaces in aqueous media which are highly dependent upon the chemical composition of the eluent. In particular, retention is controlled by the type and concentration of hard Ligand exchange is the dominant mechanism for the retention of solutes which are Lewis bases. consequently, the capacity factor and plate height depend on both the thermodynamic and kinetic properties of whatever competing Lewis bases may be present in the eluent. These Lewis base eluent components act to control retention in two ways. They modify the net ligand exchange contribution to retention, and they serve as sites for secondary interactions, such as hydrogen bonding and hydrophobic interactions between solutes and the dynamic stationary phase

    The well-known diphosphadiazane-1,3-diyl [P(μ-NTer)]2 (Ter = 2,6-bis(2,4,6-trimethyl-phenyl)-phenyl) was treated with Lewis bases such as N-heterocyclic carbenes and Lewis acids e.g. gold(i) chloride complexes. In the reaction with the Lewis base, fragmentation of the P2N2 framework was observed, yielding a salt of the type [(NHC)2P](+)[(TerN)2P](-) in a clean reaction. The reaction of [P(μ-NTer)]2 with gold(i) chloride afforded 1 : 1 and 1 : 2 complexes. The dinuclear complex [(ClAu)2P(μ-NTer)2P] displays a bridging P atom between both gold centers, as has been observed for P based zwitterions.

    An immunohistochemical analysis was employed to determine the expression of carbohydrate antigens associated to mucins in normal epithelia. Tissue samples were obtained as biopsies from normal breast (18), colon (35) and oral cavity mucosa (8). The following carbohydrate epitopes were studied: sialyl-Lewis x, Lewis x, Lewis y, Tn hapten, sialyl-Tn and Thomsen-Friedenreich antigen. Mucins were also studied employing antibodies against MUC1, MUC2, MUC4, MUC5AC, MUC6 and also normal colonic glycolipid. Statistical analysis was performed and Kendall correlations were obtained. Lewis x showed an apical pattern mainly at plasma membrane, although cytoplasmic staining was also found in most samples. TF, Tn and sTn haptens were detected in few specimens, while sLewis x was found in oral mucosa and breast tissue. Also, normal breast expressed MUC1 at a high percentage, whereas MUC4 was observed in a small number of samples. Colon specimens mainly expressed MUC2 and MUC1, while most oral mucosa samples expressed MUC4 and MUC1. A positive correlation between MUC1VNTR and TF epitope (r=0.396) was found in breast samples, while in colon specimens MUC2 and colonic glycolipid versus Lewis x were statistically significantly correlated (r=0.28 and r=0.29, respectively). As a conclusion, a defined carbohydrate epitope expression is not exclusive of normal tissue or a determined localization, and it is possible to assume that different glycoproteins and glycolipids may be carriers of carbohydrate antigens depending on the tissue localization considered.

    A Lewis base promoted deprotonative pronucleophile addition to silyl acetals has been developed and applied to the iridium-catalyzed reductive Horner-Wadsworth-Emmons (HWE) olefination of esters and the chemoselective reduction of the resulting enoates. Lewis base activation of silyl acetals generates putative pentacoordinate silicate acetals, which fragment into aldehydes, silanes, and alkoxides in situ. Subsequent deprotonative metalation of phosphonate esters followed by HWE with aldehydes furnishes enoates. This operationally convenient, mechanistically unique protocol converts the traditionally challenging aryl, alkenyl, and alkynyl esters to homologated enoates at room temperature within a single vessel.

    By 1979, after a long decline following the end of the Apollo program, the Lewis Research Center found its very existence endangered because it was not doing the kind of research that could attract funding at the time. New management under Andrew J. Stofan applied a program of strategic planning, participative management, and consensus decision making. A corporate-cultural change was effected which enabled Lewis to commit itself to four fundable research and development projects. Morale-building and training programs which were essential to this change are described.

  10. NASA Lewis Launch Collision Probability Model Developed and Analyzed

    Science.gov (United States)

    Bollenbacher, Gary; Guptill, James D

    1999-01-01

    There are nearly 10,000 tracked objects orbiting the earth. These objects encompass manned objects, active and decommissioned satellites, spent rocket bodies, and debris. They range from a few centimeters across to the size of the MIR space station. Anytime a new satellite is launched, the launch vehicle with its payload attached passes through an area of space in which these objects orbit. Although the population density of these objects is low, there always is a small but finite probability of collision between the launch vehicle and one or more of these space objects. Even though the probability of collision is very low, for some payloads even this small risk is unacceptable. To mitigate the small risk of collision associated with launching at an arbitrary time within the daily launch window, NASA performs a prelaunch mission assurance Collision Avoidance Analysis (or COLA). For the COLA of the Cassini spacecraft, the NASA Lewis Research Center conducted an in-house development and analysis of a model for launch collision probability. The model allows a minimum clearance criteria to be used with the COLA analysis to ensure an acceptably low probability of collision. If, for any given liftoff time, the nominal launch vehicle trajectory would pass a space object with less than the minimum required clearance, launch would not be attempted at that time. The model assumes that the nominal positions of the orbiting objects and of the launch vehicle can be predicted as a function of time, and therefore, that any tracked object that comes within close proximity of the launch vehicle can be identified. For any such pair, these nominal positions can be used to calculate a nominal miss distance. The actual miss distances may differ substantially from the nominal miss distance, due, in part, to the statistical uncertainty of the knowledge of the objects positions. The model further assumes that these position uncertainties can be described with position covariance matrices

    Full Text Available Here we present a complete revision of the species of Baconia. Up until now there have been 27 species assigned to the genus (Mazur, 2011, in two subgenera (Binhister Cooman and Baconia s. str., with species in the Neotropical, Nearctic, Palaearctic, and Oriental regions. We recognize all these species as valid and correctly assigned to the genus, and redescribe all of them. We synonymize Binhister, previously used for a polyphyletic assemblage of species with varied relationships in the genus. We move four species into Baconia from other genera, and describe 85 species as new, bringing the total for the genus to 116 species.

    2013-01-01

    Here we present a complete revision of the species of Baconia. Up until now there have been 27 species assigned to the genus (Mazur, 2011), in two subgenera (Binhister Cooman and Baconia s. str.), with species in the Neotropical, Nearctic, Palaearctic, and Oriental regions. We recognize all these species as valid and correctly assigned to the genus, and redescribe all of them. We synonymize Binhister, previously used for a polyphyletic assemblage of species with varied relationships in the genus. We move four species into Baconia from other genera, and describe 85 species as new, bringing the total for the genus to 116 species. We divide these into 12 informal species groups, leaving 13 species unplaced to group. We present keys and diagnoses for all species, as well as habitus photos and illustrations of male genitalia for nearly all. The genus now contains the following species and species groups: Baconia loricata group [Baconia loricata Lewis, 1885, B. patula Lewis, 1885, Baconia gounellei (Marseul, 1887a), Baconia jubaris (Lewis, 1901), Baconia festiva (Lewis, 1891), Baconia foliosoma sp. n., Baconia sapphirina sp. n., Baconia furtiva sp. n., Baconia pernix sp. n., Baconia applanatis sp. n., Baconia disciformis sp. n., Baconia nebulosa sp. n., Baconia brunnea sp. n.], Baconia godmani group [Baconia godmani (Lewis, 1888), Baconia venusta (J.

  13. Claude Bernard Distinguished Lecture. Becoming a truly helpful teacher: considerably more challenging, and potentially more fun, than merely doing business as usual.

    Jason, Hilliard

    2007-12-01

    Few medical faculty members are adequately prepared for their instructional responsibilities. Our educational traditions were established before we had research-based understandings of the teaching-learning process and before brain research began informing our understandings of how humans achieve lasting learning. Yet, there are several advantages you may have. If your expertise is at one of the frontiers of human biology, your teaching can be inherently fascinating to aspiring health professionals. If your work has implications for human health, you have another potential basis for engaging future clinicians. And, thanks to Claude Bernard's influence, you likely are "process oriented," a necessary mindset for being an effective teacher. There are also challenges you may face. Your medical students will mostly become clinicians. Unless you can help them see connections between your offerings and their future work, you may not capture and sustain their interest. To be effective, teachers, like clinicians, need to be interactive, make on-the-spot decisions, and be "emotional literate." If you aren't comfortable with these demands, you may have work to do toward becoming a truly helpful teacher. Program changes may be needed. Might your program need to change 1) from being adversarial and controlling to being supportive and trust based or 2) from mainly dispensing information to mainly asking and inviting questions? In conclusion, making changes toward becoming a truly helpful teacher can bring benefits to your students while increasing your sense of satisfaction and fulfillment as a teacher. If you choose to change, be gentle with yourself, as you should be when expecting your students to make important changes.

  15. Compensatory shifts in visual perception are associated with hallucinations in Lewy body disorders.

    Visual hallucinations are a common, distressing, and disabling symptom of Lewy body and other diseases. Current models suggest that interactions in internal cognitive processes generate hallucinations. However, these neglect external factors. Pareidolic illusions are an experimental analogue of hallucinations. They are easily induced in Lewy body disease, have similar content to spontaneous hallucinations, and respond to cholinesterase inhibitors in the same way. We used a primed pareidolia task with hallucinating participants with Lewy body disorders (n = 16), non-hallucinating participants with Lewy body disorders (n = 19), and healthy controls (n = 20). Participants were presented with visual "noise" that sometimes contained degraded visual objects and were required to indicate what they saw. Some perceptions were cued in advance by a visual prime. Results showed that hallucinating participants were impaired in discerning visual signals from noise, with a relaxed criterion threshold for perception compared to both other groups. After the presentation of a visual prime, the criterion was comparable to the other groups. The results suggest that participants with hallucinations compensate for perceptual deficits by relaxing perceptual criteria, at a cost of seeing things that are not there, and that visual cues regularize perception. This latter finding may provide a mechanism for understanding the interaction between environments and hallucinations.

    1997-01-01

    The National Aeronautics and Space Administration's (NASA) agency-wide movement to cultivate a quality workplace is the basis for Lewis Research Center to implement Total Quality Fundamentals (TQF) initiatives. The Lewis Technical Services Directorate (TSD) introduced the Total Quality Fundamentals (TQF) workshops to its work force as an opportunity to introduce the concepts and principles of TQF. These workshops also provided the participants with the opportunity to dialogue with fellow TSD employees and managers. This report describes, through the perspective of the Lewis TSD TQF Coaches, how the TQF work- shop process was accomplished in TSD. It describes the structure for addressing the need, implementation process, input the TSD Coaches provided, common themes and concerns raised, conclusions, and recommendations. The Coaches concluded that these types of workshops could be the key to open the communication channels that are necessary to help everyone at Lewis understand where they fit in the organization. TQF workshops can strengthen the participant's connection with the Mission, Vision of the Center, and Vision of the Agency. Reconunendations are given based on these conclusions that can help the TSD Quality Board develop attainable measures towards a quality workplace.

    Accumulation of phosphorylated α-synuclein in neurons and glial cells is a histological hallmark of Lewy body disease (LBD) and multiple system atrophy (MSA). Recently, filamentous aggregations of phosphorylated α-synuclein have been reported in the cytoplasm of Schwann cells, but not in axons, in the peripheral nervous system in MSA, mainly in the cranial and spinal nerve roots. Here we conducted an immunohistochemical investigation of the cranial and spinal nerves and dorsal root ganglia of patients with LBD. Lewy axons were found in the oculomotor, trigeminal and glossopharyngeal-vagus nerves, but not in the hypoglossal nerve. The glossopharyngeal-vagus nerves were most frequently affected, with involvement in all of 20 subjects. In the spinal nerve roots, Lewy axons were found in all of the cases examined. Lewy axons in the anterior nerves were more frequent and numerous in the thoracic and sacral segments than in the cervical and lumbar segments. On the other hand, axonal lesions in the posterior spinal nerve roots appeared to increase along a cervical-to-sacral gradient. Although Schwann cell cytoplasmic inclusions were found in the spinal nerves, they were only minimal. In the dorsal root ganglia, axonal lesions were seldom evident. These findings indicate that α-synuclein pathology in the peripheral nerves is axonal-predominant in LBD, whereas it is restricted to glial cells in MSA. © 2015 Japanese Society of Neuropathology.

    Directory of Open Access Journals (Sweden)

    2017-01-01

    Full Text Available To ensure that consumers understand financial products’ “costs, benefits, and risks,” the Consumer Financial Protection Bureau has been redesigning mandated disclosures, primarily through iterative lab testing. But no matter how well these disclosures perform in experiments, firms will run circles around the disclosures when studies end and marketing begins. To meet the challenge of the dynamic twenty-first-century consumer financial marketplace, the bureau should require firms to demonstrate that a good proportion of their customers understand key pertinent facts about the financial products they buy. Comprehension rules would induce firms to inform consumers and simplify products, tasks that firms are better equipped than the bureau to perform.

    2017-07-01

    Full Text Available We present a 35-year-old male patient with Bureau-Barrière syndrome. Bureau-Barrière syndrome is an ulcero-mutilating acropathy almost invariably associated with excessive alcohol intake. It presents with a triad of trophic skin changes with recurrent ulcerations, bone lesions and nerve damage. The clinical presentation includes chronic painless plantar ulcerations with periulcerous hyperkeratosis, hyperhidrosis, livedoid skin colour, nail dystrophy, widening and infiltration of the toes and common interdigital mycoses. Other non-specific skin changes related to the alcohol consumption are commonly observed as well. The condition affects mainly middle-aged men suffering from alcoholism. Often a bilateral location at the lower limb of male alcoholics has been described, as in our patient. Successful treatment of the Bureau-Barrière syndrome requires an interdisciplinary approach. Cessation of alcohol intake and smoking is of paramount importance.

  19. Building new discrete supramolecular assemblies through the interaction of iso-tellurazole N-oxides with Lewis acids and bases.

    Ho, Peter C; Jenkins, Hilary A; Britten, James F; Vargas-Baca, Ignacio

    2017-10-13

    The supramolecular macrocycles spontaneously assembled by iso-tellurazole N-oxides are stable towards Lewis bases as strong as N-heterocyclic carbenes (NHC) but readily react with Lewis acids such as BR 3 (R = Ph, F). The electron acceptor ability of the tellurium atom is greatly enhanced in the resulting O-bonded adducts, which consequently enables binding to a variety of Lewis bases that includes acetonitrile, 4-dimethylaminopyridine, 4,4'-bipyridine, triphenyl phosphine, a N-heterocyclic carbene and a second molecule of iso-tellurazole N-oxide.

  20. An order in Lewy body disorders: Retrograde degeneration in hyperbranching axons as a fundamental structural template accounting for focal/multifocal Lewy body disease.

    Science.gov (United States)

    Uchihara, Toshiki

    2017-04-01

    Initial clinical recognition of "paralysis agitans" by James Parkinson was expanded by Jean-Martin Charcot, who recognized additional clinical findings of his own, such as slowness (distinct from paralysis), rigidity (distinct from spasticity) and characteristic countenance. Charcot assembled these findings under the umbrella of "Parkinson disease (PD)". This purely clinical concept was so prescient and penetrating that subsequent neuropathological and biochemical evidences were ordered along this axis to establish the nigra-central trinity of PD (dopamine depletion, nigral lesion with Lewy bodies: LBs). Although dramatic efficacy of levodopa boosted an enthusiasm for this nigra-centralism, extranigral lesions were identified, especially after identification of alpha-synuclein (αS) as a major constituent of LBs. Frequent αS lesions in the lower brainstem with their presumed upward spread were coupled with the self-propagating property of αS molecule, as a molecular template, to constitute the prion-Braak hypothesis. This hybrid concept might expectedly explain clinical, structural and biochemical features of PD/dementia with Lewy bodies (DLB) as if they were stereotypic. In spite of this ordered explanation, recent studies have demonstrated unexpectedly that αS lesions in the human brain, as well as their corresponding clinical manifestations, are much more disordered. Even with such a chaos of LB disorders, affected neuronal groups are uniformly characterized by hyperbranching axons, which may facilitate distal-dominant degeneration and retrograde progression of LB-related degeneration along axons as a fundamental structural order to template LB disorders. This "structural template" hypothesis may explain why: (i) some selective groups are prone to develop Lewy pathology; (ii) their clinical manifestations (especially non-motor components) are vague and generalized without somatotopic accentuation; (iii) distal axons and terminals are preferentially affected

    2014-04-01

    This article announces the recipient of the 2014 inaugural Werner Kalow Responsible Innovation Prize in Global Omics and Personalized Medicine by the Pacific Rim Association for Clinical Pharmacogenetics (PRACP): Bernard Lerer, professor of psychiatry and director of the Biological Psychiatry Laboratory, Hadassah-Hebrew University Medical Center, Jerusalem, Israel. The Werner Kalow Responsible Innovation Prize is given to an exceptional interdisciplinary scholar who has made highly innovative and enduring contributions to global omics science and personalized medicine, with both vertical and horizontal (transdisciplinary) impacts. The prize is established in memory of a beloved colleague, mentor, and friend, the late Professor Werner Kalow, who cultivated the idea and practice of pharmacogenetics in modern therapeutics commencing in the 1950s. PRACP, the prize's sponsor, is one of the longest standing learned societies in the Asia-Pacific region, and was founded by Kalow and colleagues more than two decades ago in the then-emerging field of pharmacogenetics. In announcing this inaugural prize and its winner, we seek to highlight the works of prize winner, Professor Lerer. Additionally, we contextualize the significance of the prize by recalling the life and works of Professor Kalow and providing a brief socio-technical history of the rise of pharmacogenetics and personalized medicine as a veritable form of 21(st) century scientific practice. The article also fills a void in previous social science analyses of pharmacogenetics, by bringing to the fore the works of Kalow from 1995 to 2008, when he presciently noted the rise of yet another field of postgenomics inquiry--pharmacoepigenetics--that railed against genetic determinism and underscored the temporal and spatial plasticity of genetic components of drug response, with invention of the repeated drug administration (RDA) method that estimates the dynamic heritabilities of drug response. The prize goes a long way

  5. ɑ-Synuclein strains and seeding in Parkinson's disease, incidental Lewy body disease, dementia with Lewy bodies and multiple system atrophy: similarities and differences.

    Science.gov (United States)

    Peelaerts, W; Bousset, L; Baekelandt, V; Melki, R

    2018-04-27

    Several age-related neurodegenerative disorders are characterized by the deposition of aberrantly folded endogenous proteins. These proteins have prion-like propagation and amplification properties but so far appear nontransmissible between individuals. Because of the features they share with the prion protein, PrP, the characteristics of pathogenic protein aggregates in several progressive brain disorders, including different types of Lewy body diseases (LBDs), such as Parkinson's disease (PD), multiple system atrophy (MSA) and dementia with Lewy bodies (DLB), have been actively investigated. Even though the pleomorphic nature of these syndromes might suggest different underlying causes, ɑ-synuclein (ɑSyn) appears to play an important role in this heterogeneous group of diseases (the synucleinopathies). An attractive hypothesis is that different types of ɑSyn protein assemblies have a unique and causative role in distinct synucleinopathies. We will discuss the recent research progress on ɑSyn assemblies involved in PD, MSA and DLB; their behavior as strains; current spreading hypotheses; their ability to seed centrally and peripherally; and their implication for disease pathogenesis.

  6. Brush Polymer of Donor-Accepter Dyads via Adduct Formation between Lewis Base Polymer Donor and All Carbon Lewis Acid Acceptor

    Directory of Open Access Journals (Sweden)

    Yang Wang

    2017-09-01

    Full Text Available A synthetic method that taps into the facile Lewis base (LB→Lewis acid (LA adduct forming reaction between the semiconducting polymeric LB and all carbon LA C60 for the construction of covalently linked donor-acceptor dyads and brush polymer of dyads is reported. The polymeric LB is built on poly(3-hexylthiophene (P3HT macromers containing either an alkyl or vinyl imidazolium end group that can be readily converted into the N-heterocyclic carbene (NHC LB site, while the brush polymer architecture is conveniently constructed via radical polymerization of the macromer P3HT with the vinyl imidazolium chain end. Simply mixing of such donor polymeric LB with C60 rapidly creates linked P3HT-C60 dyads and brush polymer of dyads in which C60 is covalently linked to the NHC junction connecting the vinyl polymer main chain and the brush P3HT side chains. Thermal behaviors, electronic absorption and emission properties of the resulting P3HT-C60 dyads and brush polymer of dyads have been investigated. The results show that a change of the topology of the P3HT-C60 dyad from linear to brush architecture enhances the crystallinity and Tm of the P3HT domain and, along with other findings, they indicate that the brush polymer architecture of donor-acceptor domains provides a promising approach to improve performances of polymer-based solar cells.

  7. NASA Lewis Helps Company With New Single-Engine Business Turbojet

    Science.gov (United States)

    1998-01-01

    Century Aerospace Corporation, a small company in Albuquerque, New Mexico, is developing a six-seat aircraft powered by a single turbofan engine for general aviation. The company had completed a preliminary design of the jet but needed analyses and testing to proceed with detailed design and subsequent fabrication of a prototype aircraft. NASA Lewis Research Center used computational fluid dynamics (CFD) analyses to ferret out areas of excessive curvature in the inlet where separation might occur. A preliminary look at the results indicated very good inlet performance; and additional calculations, performed with vortex generators installed in the inlet, led to even better results. When it was initially determined that the airflow distortion pattern at the compressor face fell outside of the limits set by the engine manufacturer, the Lewis team studied possible solutions, selected the best, and provided recommendations. CFD results for the inlet system were so good that wind tunnel tests were unnecessary.

  8. Elk Monitoring Protocol for Lewis and Clark National Historical Park, Version 1.0

    Science.gov (United States)

    Jenkins, Kurt J.; Griffin, Paul C.; Boetsch, John R.; Cole, Carla

    2011-01-01

    Maintaining elk (Cervus elaphus roosevelti) herds that frequent Lewis and Clark National Historical Park (NHP) is central to the park’s purpose of preserving the historic, cultural, scenic, and natural resources. Elk were critical to sustaining the members of the Lewis and Clark expedition by providing food and clothing over the winter of 1805-1806. Today, elk viewing opportunities in the park and surrounding region generate broad appeal with the visiting public, which number over 250,000 per year at the Fort Clatsop visitor center. This protocol describes procedures for monitoring trends in the use of the Fort Clatsop area by Roosevelt elk. Specific objectives of elk monitoring in Lewis and Clark NHP are to measure the relative use and proportion of area used by elk during winter in the Fort Clatsop Unit of the park, and the rate at which elk are sighted from roads in and around the park. Relative use and the proportion of area used by elk are determined from elk fecal pellet surveys conducted every other year in the Fort Clatsop park unit. Pairs of observers visit a systematic array of permanent plots in the fall to clear them of elk fecal pellets, and return to the plots in late winter to count elk fecal pellets that have accumulated during winter. Half of the subplots are counted by two independent observers, which allows for the estimation of relative use and proportion of area occupied by elk with analyses of detection biases that account for unseen elk pellet groups. Standardized road surveys are conducted in and near the Fort Clatsop park unit three or four times monthly during alternate months. Data from road surveys are used to quantify the rate that park visitors would be expected to see elk, when driving the selected set of routes. The monitoring protocol is based on three field seasons of development and testing. The protocol narrative describes the background, rationale, sampling design, field methods, analytical methods, data management, reporting

  9. Gallium-containing polymer brush film as efficient supported Lewis acid catalyst in a glass microreactor

    Directory of Open Access Journals (Sweden)

    Rajesh Munirathinam

    2013-08-01

    Full Text Available Polystyrene sulfonate polymer brushes, grown on the interior of the microchannels in a microreactor, have been used for the anchoring of gallium as a Lewis acid catalyst. Initially, gallium-containing polymer brushes were grown on a flat silicon oxide surface and were characterized by FTIR, ellipsometry, and X-ray photoelectron spectroscopy (XPS. XPS revealed the presence of one gallium per 2–3 styrene sulfonate groups of the polymer brushes. The catalytic activity of the Lewis acid-functionalized brushes in a microreactor was demonstrated for the dehydration of oximes, using cinnamaldehyde oxime as a model substrate, and for the formation of oxazoles by ring closure of ortho-hydroxy oximes. The catalytic activity of the microreactor could be maintained by periodic reactivation by treatment with GaCl3.

  10. Applied high-speed imaging for the icing research program at NASA Lewis Research Center

    Science.gov (United States)

    Slater, Howard; Owens, Jay; Shin, Jaiwon

    1992-01-01

    The Icing Research Tunnel at NASA Lewis Research Center provides scientists a scaled, controlled environment to simulate natural icing events. The closed-loop, low speed, refrigerated wind tunnel offers the experimental capability to test for icing certification requirements, analytical model validation and calibration techniques, cloud physics instrumentation refinement, advanced ice protection systems, and rotorcraft icing methodology development. The test procedures for these objectives all require a high degree of visual documentation, both in real-time data acquisition and post-test image processing. Information is provided to scientific, technical, and industrial imaging specialists as well as to research personnel about the high-speed and conventional imaging systems will be on the recent ice protection technology program. Various imaging examples for some of the tests are presented. Additional imaging examples are available from the NASA Lewis Research Center's Photographic and Printing Branch.

  11. Autoinduced catalysis and inverse equilibrium isotope effect in the frustrated Lewis pair catalyzed hydrogenation of imines.

    2015-05-26

    The frustrated Lewis pair (FLP)-catalyzed hydrogenation and deuteration of N-benzylidene-tert-butylamine (2) was kinetically investigated by using the three boranes B(C6F5)3 (1), B(2,4,6-F3-C6H2)3 (4), and B(2,6-F2-C6H3)3 (5) and the free activation energies for the H2 activation by FLP were determined. Reactions catalyzed by the weaker Lewis acids 4 and 5 displayed autoinductive catalysis arising from a higher free activation energy (2 kcal mol(-1)) for the H2 activation by the imine compared to the amine. Surprisingly, the imine reduction using D2 proceeded with higher rates. This phenomenon is unprecedented for FLP and resulted from a primary inverse equilibrium isotope effect. © 2015 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

  13. Intermolecular interactions of trifluorohalomethanes with Lewis bases in the gas phase: an ab initio study.

    Science.gov (United States)

    Wang, Yi-Siang; Yin, Chih-Chien; Chao, Sheng D

    2014-10-07

    We perform an ab initio computational study of molecular complexes with the general formula CF3X-B that involve one trifluorohalomethane CF3X (X = Cl or Br) and one of a series of Lewis bases B in the gas phase. The Lewis bases are so chosen that they provide a range of electron-donating abilities for comparison. Based on the characteristics of their electron pairs, we consider the Lewis bases with a single n-pair (NH3 and PH3), two n-pairs (H2O and H2S), two n-pairs with an unsaturated bond (H2CO and H2CS), and a single π-pair (C2H4) and two π-pairs (C2H2). The aim is to systematically investigate the influence of the electron pair characteristics and the central atom substitution effects on the geometries and energetics of the formed complexes. The counterpoise-corrected supermolecule MP2 and coupled-cluster single double with perturbative triple [CCSD(T)] levels of theory have been employed, together with a series of basis sets up to aug-cc-pVTZ. The angular and radial configurations, the binding energies, and the electrostatic potentials of the stable complexes have been compared and discussed as the Lewis base varies. For those complexes where halogen bonding plays a significant role, the calculated geometries and energetics are consistent with the σ-hole model. Upon formation of stable complexes, the C-X bond lengths shorten, while the C-X vibrational frequencies increase, thus rendering blueshifting halogen bonds. The central atom substitution usually enlarges the intermolecular bond distances while it reduces the net charge transfers, thus weakening the bond strengths. The analysis based on the σ-hole model is grossly reliable but requires suitable modifications incorporating the central atom substitution effects, in particular, when interaction components other than electrostatic contributions are involved.

    The cultural turn of the twentieth century’s last quarter gradually led to a new approach to the classical objects of historical research. Historians nowadays are required to take on a 'cultural perspective' in the course of their studies. Using the example of a particular piece of the Lewis Chessmen this paper examines both the benefits and the limitations that come about with the cultural approach and cautions against a too rigid application.

    In FY1999, Pacific Northwest National Laboratory conducted an energy efficiency campaign for residential housing at the Fort Lewis Army Installation near Tacoma, Washington. Preliminary weather-corrected calculations show energy savings of 10{percent} from FY98 for energy use in family housing. This exceeded the project's goal of 3{percent}. The work was funded by the U.S. DOEs Federal Energy Management Program (FEMP), Office of Energy Efficiency and Renewable Energy. The project adapted FEMP's national ``You Have the Power Campaign'' at the local level, tailoring it to the military culture. The applied research project was designed to demonstrate the feasibility of tailored, research-based strategies to promote energy conservation in military family housing. In contrast to many energy efficiency efforts, the campaign focused entirely on actions residents could take in their own homes, as opposed to technology or housing upgrades. Behavioral change was targeted because residents do not pay their own utility bills; thus other motivations must drive personal energy conservation. This campaign augments ongoing energy savings from housing upgrades carried out by Fort Lewis. The campaign ran from September 1998 through August 1999. The campaign strategy was developed based on findings from previous research and on input from residents and officials at Fort Lewis. Energy use, corrected to account for weather differences, was compared with the previous year's use. Survey responses from 377 of Fort Lewis residents of occupied housing showed that the campaign was moderately effective in promoting behavior change. Of those who were aware of the campaign, almost all said they were now doing one or more energy-efficient things that they had not done before. Most people were motivated by the desire to do the right thing and to set a good example for their children. They were less motivated by other factors.

    In humans, growth hormone deficiency (GHD) and low circulating levels of insulin-like growth factor 1 (IGF-1) significantly increase the risk for cerebrovascular disease. Genetic growth hormone (GH)/IGF-1 deficiency in Lewis dwarf rats significantly increases the incidence of late-life strokes, similar to the effects of GHD in elderly humans. Peripubertal treatment of Lewis dwarf rats with GH delays the occurrence of late-life stroke, which results in a significant extension of life span. The present study was designed to characterize the vascular effects of life span-extending peripubertal GH replacement in Lewis dwarf rats. Here, we report, based on measurements of dihydroethidium fluorescence, tissue isoprostane, GSH, and ascorbate content, that peripubertal GH/IGF-1 deficiency in Lewis dwarf rats increases vascular oxidative stress, which is prevented by GH replacement. Peripubertal GHD did not alter superoxide dismutase or catalase activities in the aorta nor the expression of Cu-Zn-SOD, Mn-SOD, and catalase in the cerebral arteries of dwarf rats. In contrast, cerebrovascular expression of glutathione peroxidase 1 was significantly decreased in dwarf vessels, and this effect was reversed by GH treatment. Peripubertal GHD significantly decreases expression of the Nrf2 target genes NQO1 and GCLC in the cerebral arteries, whereas it does not affect expression and activity of endothelial nitric oxide synthase and vascular expression of IGF-1, IGF-binding proteins, and inflammatory markers (tumor necrosis factor alpha, interluekin-6, interluekin-1β, inducible nitric oxide synthase, intercellular adhesion molecule 1, and monocyte chemotactic protein-1). In conclusion, peripubertal GH/IGF-1 deficiency confers pro-oxidative cellular effects, which likely promote an adverse functional and structural phenotype in the vasculature, and results in accelerated vascular impairments later in life.

    Fitzpatrick, J.J.; Muhs, D.R.

    1989-01-01

    During the 1987-1988 austral summer field season, membersof the south party of the antarctic search for meteorites south-ern team* working in the Lewis Cliff/Colbert Hills region dis-covered several areas of unusual mineralization within theLewis Cliff ice tongue and its associated moraine field (figure1). The Lewis Cliff ice tongue (84°15'S 161°25'E) is a meteorite-stranding surface of ablating blue ice, about 2.3 by 7.0 kilo-meters, bounded on the west by the Lewis Cliff, on the northand northeast by a large supraglacial moraine, and on the eastby the Colbert Hills. To the south it opens to the Walcott Névé.Because it is a meteorite-stranding surface, the major component of ice motion in the area is believed to be vertical(Whillans and Cassidy 1983). The presence of Thule-Baffinmoraines at the northern terminus of the blue ice tends tosupport the hypothesis that the area underlying the moraineis essentially stagnant and that ice arriving from the south ispiling up against it. Areas containing mineral deposits werefound within the moraine field to the north and east of theblue ice margin and also along the east margins of the blue iceitself. Subsequent X-ray diffraction analyses of these depositshave shown that they are composed predominantly of nah-colite (NaHCO3), trona [Na3(CO3)(HCO3) · 2H20], borax[Na2B405(OH)4 · 8H20], and a new hexagonal hydrous sulfatespecies. This paper reports the details of the borax occurrence,because it is the first known on the continent.

  5. Terrestrial ages of ordinary chondrites from the lewis cliff stranding area, East Antarctica

    1999-07-01

    We determined terrestrial ages of ordinary chondrites from the Lewis Cliff stranding area, East Antarctica, on the basis of the concentrations of cosmogenic 10Be (t1/2 = 1.51 Ma), 26Al (t1/2 = 0.705 Ma) and 36Cl (t1/2 = 0.301 Ma). After an initial 26Al -ray survey of 91 meteorites suggested that many have terrestrial ages larger than 0.1 Ma, we selected 62 meteorites for 10Be and 26Al measurements by accelerator mass spectrometry (AMS) and measured 36Cl in twelve of those. Low terrestrial ages (Ma) were found for about 60% of the meteorites, whereas all others have ages between 0.1 and 0.5 Ma, except for one exceptional age of >2 Ma (Welten et al., 1997). Our major conclusions are: (1) The Lewis Cliff H-chondrites show similar ages as those from the Allan Hills Ice-fields, but the L-chondrites are about a factor of two younger than those from Allan Hills, which indicates that Lewis Cliff is a younger stranding area. (2) The terrestrial age distributions at different parts of the Lewis Cliff stranding area generally agree with simple meteorite concentration models, although differences in weathering rate may also play a role. (3) We confirm that meteorites with natural thermoluminescence (TL) levels >80 krad are associated with low terrestrial ages (Benoit et al., 1992), but conclude that natural TL levels <80 krad can not be used to calculate the terrestrial age of a meteorite. Natural TL levels do seem useful to estimate relative terrestrial ages of large groups of meteorites and to determine differences in surface exposure age of paired meteorite fragments. (4) Of the 62 meteorites measured with AMS, 31 were assigned to eleven different pairing groups, mainly on the basis of their cosmogenic nuclide record. The meteorites are estimated to represent between 42 and 52 distinct falls.

    The [4 + 2] acido-catalyzed heterocycloaddition between new beta-substituted N-vinyl-1,3-oxazolidin-2-ones (with R' = Me, Ar, CH2 Ar) and beta,gamma-unsaturated alpha-ketoesters (R = Ar) afforded heteroadducts with high levels of endo and facial selectivities. A complete reversal of facial differentiation was achieved by varying the Lewis acid, leading to the stereoselective formation of either endo-alpha or endo-beta adducts. [reaction: see text].

    We report herein the synthesis and full characterization of the donor-free Lewis superacids Al(OR(F))(3) with OR(F) = OC(CF(3))(3) (1) and OC(C(5)F(10))C(6)F(5) (2), the stabilization of 1 as adducts with the very weak Lewis bases PhF, 1,2-F(2)C(6)H(4), and SO(2), as well as the internal C-F activation pathway of 1 leading to Al(2)(F)(OR(F))(5) (4) and trimeric [FAl(OR(F))(2)](3) (5, OR(F) = OC(CF(3))(3)). Insights have been gained from NMR studies, single-crystal structure determinations, and DFT calculations. The usefulness of these Lewis acids for halide abstractions has been demonstrated by reactions with trityl chloride (NMR; crystal structures). The trityl salts allow the introduction of new, heteroleptic weakly coordinating [Cl-Al(OR(F))(3)](-) anions, for example, by hydride or alkyl abstraction reactions.

    Precise control of the electronic surface states of two-dimensional (2D) materials could improve their versatility and widen their applicability in electronics and sensing. To this end, chemical surface functionalization has been used to adjust the electronic properties of 2D materials. So far, however, chemical functionalization has relied on lattice defects and physisorption methods that inevitably modify the topological characteristics of the atomic layers. Here we make use of the lone pair electrons found in most of 2D metal chalcogenides and report a functionalization method via a Lewis acid-base reaction that does not alter the host structure. Atomic layers of n-type InSe react with Ti4+ to form planar p-type [Ti4+n(InSe)] coordination complexes. Using this strategy, we fabricate planar p-n junctions on 2D InSe with improved rectification and photovoltaic properties, without requiring heterostructure growth procedures or device fabrication processes. We also show that this functionalization approach works with other Lewis acids (such as B3+, Al3+ and Sn4+) and can be applied to other 2D materials (for example MoS2, MoSe2). Finally, we show that it is possible to use Lewis acid-base chemistry as a bridge to connect molecules to 2D atomic layers and fabricate a proof-of-principle dye-sensitized photosensing device.

    Background Visual hallucinations and visuoperceptual deficits are common in dementia with Lewy bodies, suggesting that cortical visual function may be abnormal. Aims To investigate: (1) cortical visual function using functional magnetic resonance imaging (fMRI); and (2) the nature and severity of perfusion deficits in visual areas using arterial spin labelling (ASL)-MRI. Method In total, 17 participants with dementia with Lewy bodies (DLB group) and 19 similarly aged controls were presented with simple visual stimuli (checkerboard, moving dots, and objects) during fMRI and subsequently underwent ASL-MRI (DLB group n = 15, control group n = 19). Results Functional activations were evident in visual areas in both the DLB and control groups in response to checkerboard and objects stimuli but reduced visual area V5/MT (middle temporal) activation occurred in the DLB group in response to motion stimuli. Posterior cortical perfusion deficits occurred in the DLB group, particularly in higher visual areas. Conclusions Higher visual areas, particularly occipito-parietal, appear abnormal in dementia with Lewy bodies, while there is a preservation of function in lower visual areas (V1 and V2/3).

  10. Efficient Lewis Acid Ionic Liquid-Catalyzed Synthesis of the Key Intermediate of Coenzyme Q10 under Microwave Irradiation

    Directory of Open Access Journals (Sweden)

    Thomas Efferth

    2010-12-01

    Full Text Available An efficient synthesis of a valuable intermediate of coenzyme Q10 by microwave-assisted Lewis acidic ionic liquid (IL-catalyzed Friedel-Crafts alkylation is reported. The acidity of six [Etpy]BF4-based ionic liquids was characterized by means of the FT-IR technique using acetonitrile as a molecular probe. The catalytic activities of these ionic liquids were correlated with their Lewis acidity. With increasing Lewis acid strength of the ionic liquids, their catalytic activity in the Friedel-Crafts reaction increased, except for [Etpy]BF4-AlCl3. The effects of the reaction system, the molar fraction of Lewis acid in the Lewis acid ILs and heating techniques were also investigated. Among the six Lewis acid ionic liquids tested [Etpy]BF4-ZnCl2 showed the best catalytic activity, with a yield of 89% after a very short reaction time (150 seconds. This procedure has the advantages of higher efficiency, better reusability of ILs, energy conservation and eco-friendliness. The method has practical value for preparation of CoQ10 on an industrial scale.

    Few patients are reported with dementia with Lewy bodies before fifty years-old, which may partly reflect the difficulty of accurate diagnosis in young population. We report the case of a 44-year-old male with pathologically confirmed sporadic dementia with Lewy bodies, who did not fulfil the revised clinical criteria for this disease. We document this atypical case with clinical and cognitive evaluation, imaging, biochemistry, genetics and pathology investigations. Creutzfeldt-Jakob disease was first suspected in this patient with no previous medical history, who developed acute and rapid cognitive impairment, L-dopa-non-responsive parkinsonism, and delusion. Positive 14-3-3 protein was initially detected in cerebrospinal fluid and until the late stages of the disease. Severe atrophy with no diffusion hypersignal was found on structural MRI as well as an extensive hypometabolism on (18)F-FDG-PET, in comparison to age-matched healthy volunteers. Genetic investigation found no alpha-synuclein gene mutation. The patient died within 5 years, and post-mortem examination found numerous Lewy bodies and Lewy neurites consistent with pure Lewy body disease. This comprehensively described case illustrates that dementia with Lewy bodies can occur in young patients with atypical clinical presentation. Biochemistry and neuroimaging investigations can sometimes be insufficient to allow accurate diagnostic. More specific markers to support such diagnosis are needed.

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

  13. [Public health and agrarian liberal politics in Spain: the Rural Health Bureau (1910-1918).].

    This paper reviews the meaning of the Rural Health Bureau (1910-1918) for the history of Spanish public health, thanks to a wealth of previously unknown sources found through a systematic search through medical journals of the time and the Bulletin of the national department of Agriculture. The Bureau was dependent of the Ministry of Development, in the same way as the competences on animal health. It aimed to provide a public health rationale for a plan of agrarian infrastructures, a goal resolved into a huge task of surveillance on hookworm disease, malaria, water supplies, and diet. Thus it becomes a perfect paradigm of the Spanish Liberal tradition of promoting information instead than actual changes into society, as well as a needed complement to the hydraulic policy sponsored by Rafael Gasset.

    Full Text Available A doença de Jorge Lobo é uma micose de evolução crônica, causada pelo Lacazia loboi. Os mecanismos envolvidos na suscetibilidade/resistência do hospedeiro frente ao agente não estão ainda elucidados, dentre eles encontra-se a constituição genética. Portanto, o objetivo deste trabalho é avaliar a distribuição dos grupos sangüíneos ABO e Lewis de pacientes com doença de Jorge Lobo em relação à população geral. Foram analisados 13 pacientes provenientes do estado do Acre, 60 indivíduos da região de Bauru (SP não acometidos pela doença em estudo (grupo controle Lewis e 2.673 doadores do Banco de Sangue da cidade de Rio Branco (AC como grupo controle ABO. As presenças dos antígenos eritrocitários foram determinadas pela reação de aglutinação em tubo através dos soros anti-AB, anti-A e anti-B para o fenótipo ABO e dos soros anti-Lewis a e Lewis b para fenotipagem Lewis. As freqüências fenotípicas Lewis e ABO nos pacientes e nos controles são, respectivamente: Le (a- b+ = 54,0% X 72,0%, Le (a+ b- = 15,0% X 6,0%, Le (a- b- = 31,0% X 22,0% ; A =15,4% X 33,6%, B = 30,8% X 10,8%, O = 53,8% X 52,9%, AB = 0 X 2,7%. Embora não tenhamos encontrado resultados estatisticamente significantes, nossos achados sugerem existir suscetibilidade à doença de Jorge Lobo em indivíduos com fenótipo B e com menor freqüência fenotípica Lewis b, conferindo assim um grau de importância epidemiológica como grupo de risco naquele meio ambiente.Jorge Lobo's disease is a mycosis with chronic evolution caused by the fungus Lacazia loboi. The mechanisms involved in host resistance and susceptibility to the agent, including aspects relating to the genetic background, are still not clear. The objective of the present study, therefore, is to evaluate the ABO and Lewis blood group distributions in Jorge Lobo's disease patients compared to the general population.

    The objective of this project is to understand the mechanistic aspects behind the cooperative activation of oxygenates by catalytic pairs in aqueous media. Specifically, we will investigate how the reactivity of a solid Lewis acid can be modulated by pairing the active site with other catalytic sites at the molecular level, with the ultimate goal of enhancing activation of targeted functional groups. Although unusual catalytic properties have been attributed to the cooperative effects promoted by such catalytic pairs, virtually no studies exist detailing the use heterogeneous water-tolerant Lewis pairs. A main goal of this work is to devise rational pathways for the synthesis of porous heterogeneous catalysts featuring isolated Lewis pairs that are active in the transformation of biomass-derived oxygenates in the presence of bulk water. Achieving this technical goal will require closely linking advanced synthesis techniques; detailed kinetic and mechanistic investigations; strict thermodynamic arguments; and comprehensive characterization studies of both materials and reaction intermediates. For the last performance period (2014-2015), two technical aims were pursued: 1) C-C coupling using Lewis acid and base pairs in Lewis acidic zeolites. Tin-, zirconium-, and hafnium containing zeolites (e.g., Sn-, Zr-, and Hf-Beta) are versatile solid Lewis acids that selectively activate carbonyl functional groups. In this aim, we demonstrate that these zeolites catalyze the cross-aldol condensation of aromatic aldehydes with acetone under mild reaction conditions with near quantitative yields. NMR studies with isotopically labeled molecules confirm that acid-base pairs in the Si-O-M framework ensemble promote soft enolization through α-proton abstraction. The Lewis acidic zeolites maintain activity in the presence of water and, unlike traditional base catalysts, in acidic solutions. 2) One-pot synthesis of MWW zeolite nanosheets for activation of bulky substrates.

    Abstract This article announces the recipient of the 2014 inaugural Werner Kalow Responsible Innovation Prize in Global Omics and Personalized Medicine by the Pacific Rim Association for Clinical Pharmacogenetics (PRACP): Bernard Lerer, professor of psychiatry and director of the Biological Psychiatry Laboratory, Hadassah-Hebrew University Medical Center, Jerusalem, Israel. The Werner Kalow Responsible Innovation Prize is given to an exceptional interdisciplinary scholar who has made highly innovative and enduring contributions to global omics science and personalized medicine, with both vertical and horizontal (transdisciplinary) impacts. The prize is established in memory of a beloved colleague, mentor, and friend, the late Professor Werner Kalow, who cultivated the idea and practice of pharmacogenetics in modern therapeutics commencing in the 1950s. PRACP, the prize's sponsor, is one of the longest standing learned societies in the Asia-Pacific region, and was founded by Kalow and colleagues more than two decades ago in the then-emerging field of pharmacogenetics. In announcing this inaugural prize and its winner, we seek to highlight the works of prize winner, Professor Lerer. Additionally, we contextualize the significance of the prize by recalling the life and works of Professor Kalow and providing a brief socio-technical history of the rise of pharmacogenetics and personalized medicine as a veritable form of 21st century scientific practice. The article also fills a void in previous social science analyses of pharmacogenetics, by bringing to the fore the works of Kalow from 1995 to 2008, when he presciently noted the rise of yet another field of postgenomics inquiry—pharmacoepigenetics—that railed against genetic determinism and underscored the temporal and spatial plasticity of genetic components of drug response, with invention of the repeated drug administration (RDA) method that estimates the dynamic heritabilities of drug response. The prize goes a
