  1. Caring for Ivan Ilyich.

    Charlton, Blake; Verghese, Abraham

    2010-01-01

    For over a century, Leo Tolstoy's The Death of Ivan Ilych has been one of the most influential examinations of how we come to terms with our own mortality. Of the many who care for Ivan Ilych, only the uneducated peasant, Gerasim, is able to help him find meaning and resolution before death. An excerpt that describes Gerasim's key interaction with Ivan Ilych is provided. Analysis of the text reveals how cultural values may hinder a patient's ability to confront mortality and how unique social barriers inhibit different caretakers' ability to care for a dying patient.

  2. Intervista a Ivan Fedele

    Marco Ligabue

    2010-12-01

    Full Text Available The interview to Ivan Fedele – which opens this number of Music / Technology as ‘provoking’ element – expresses the composer’s attitude towards technology – mainly found in computer music –, the use he made within his work, as well as the developments generally considered harbingers of more interesting perspectives for the future. Several passages stress the primacy of the compositional idea on the technological means and the need of the composer to maintain control of the situation without giving up the prerogatives of the medium; indeed, it must be ‘bent’ – if not specifically designed – to the requirements of the compositional idea.

  7. Un poema epico neolatino su Ivan Mazepa

    Directory of Open Access Journals (Sweden)

    Giovanna Siedina

    2007-12-01

    Full Text Available A Neo-Latin Poem on Ivan Mazepa The author publishes for the first time, translates into Italian, and analyzes a Neo-Latin poem devoted to the Ukrainian hetman Ivan Mazepa, which celebrates the conquest of a few Turkish fortresses along the Dnipro (1695. A peculiar feature of this poem is that, on the one side, it is one of the few, or even the only epic poem devoted to the Ukrainian hetman, while on the other it is modeled, at least partly, on Virgil’s Aeneid. The poem, however, also shows some features of the panegyric genre. The author points out the many linguistic-literary and historical reminiscences, especially those of Latin epic authors and Roman history, but also of the panegyric discourse elaborated by the Latin-Polish rhetorical tradition. Through these reminiscences, the author of the poem aspires to insert the history of Ukraine-Hetmanščyna into the European Latinitas by underlining the glorious deeds of its hetman Ivan Mazepa, whose fundamental contribution to the antemurale christianitatis and to Russian history only recently has begun to be assessed in an objective and unprejudiced manner.

    To evaluate the impact of Hurricane Ivan, which made landfall east of Mobile, Alabama, on September 16, 2004, on pharmacies in the affected areas. Retrospective cross-sectional analysis. Baldwin County, Alabama. Pharmacy community rapid-needs-assessment survey. 41 hospital and community (chain and independent) pharmacies. Posthurricane pharmacy hours of operations, prescription volumes, infrastructure damage, and prehurricane disaster planning. During the week of the hurricane, both chain and independent community pharmacies within the evacuation zone worked significantly fewer hours (46% and 49%, respectively) and dispensed significantly fewer prescriptions (37% and 52%) compared with the same week of the prior year. Overall, 40% of pharmacies depleted their supplies of certain medications (e.g., anxiolytics, antihypertensives). A total of 60% of the chain and independent pharmacies outside the evacuation zone closed because of loss of electricity, but pharmacies with a generator were significantly less likely to report having turned away patients. The proportion of pharmacies that had a disaster plan but turned away patients or rationed or ran out of medications was similar to that of pharmacies without a disaster plan. Although Hurricane Ivan primarily affected the operation of pharmacies within the evacuation zone, pharmacies in the surrounding area were also affected because of loss of power. Emergency management officials should evaluate the efficacy of specific guidelines outlined in disaster plans and identify ways to deliver essential medications to people in disaster-affected areas.

  4. THE MOTIF OF THE PRODIGAL SON IN IVAN TURGENEV'S NOVELS

    Directory of Open Access Journals (Sweden)

    Valentina Ivanovna Gabdullina

    2013-11-01

    Full Text Available The author questions the perception of Ivan Turgenev as a “non- Christian writer” and studies the problem of the prodigal son motif functioning in a series of his novels. In his novels, Turgenev pictured different phases of the archetypal story, originating from the Gospel parable of the prodigal son. In the novel Rudin he depicted the phase of spiritual wanderings of the hero who had lost touch with his native land — Russia. In his next novels (Home of the Gentry, Fathers and Sons and Smoke, after leading his hero in circles and sending him back to his paternal home, Turgenev reconstructs the model of human behavior, represented in the parable, thereby recognizing the immutability of the idea formalized in the Gospel. The motif of the return to Russian land gets its completion in Turgenev's last novel Virgin Soil, in which the author paradoxically connects the Westernist idea with the Gospel imperative. Solomin, the son of a deacon, sent by his wise father out to Europe “to get education”, studies in England, masters the European knowledge and returns back “to his native land” to establish his own business in inland Russia. Thus, a series of Turgenev's novels, in which he portrayed different phases of social life, are interlinked with the motif of the prodigal son, who is represented by novels' main characters.

  5. GERMAN EPISTOLARY HERITAGE OF IVAN FRANKO AND ITS DOMINANT FEATURES

    Directory of Open Access Journals (Sweden)

    V.V. Tkachivsky

    2015-09-01

    Full Text Available The epistolary heritage of Ivan Franko contains over six thousand letters. German epistolary correspondence addressed to Vienna, Berlin, Budapest, Heidelberg, Freiburg, Stanislav, Chernivtsi. The author of the article analyzes also the response letters sent to I. Franko. His first letters in German were addressed to Olha Roshkevych. They were written under the strong impression that the epistolary novel “The Sorrows of Young Werther” by J.W. von Goethe had had on I. Franko. The Ukrainian writer’s correspondence with H. Kanner and I. Singer the editors of the weekly newspaper “Zeit” is an evidence of their close cooperation. I. Franko had close professional ties with V. Adler one of the founders and leaders of the Austrian social-democratic party, the editor of Vienna newspaper “Arbeiterzeitung”, as well as with V. Adler’s wife Emma. I. Franko’s correspondence with a prominent Slavic scholar V. Yagic didn’t contain only private matters discussions. The third part of it is totally scientific which actually makes it valuable for researchers. I. Franko’s epistolary works reflect his artistic writer’s style neither in form nor in content. His letters are characterized by the depth of his thought, consistency of his statements, clearness of the sentence constructions, tendency to critical assessments of phenomena and scientific findings.

  6. Photography travel journal of Belgrade by Ivan Groman a different view of the photographic work of Ivan Groman

    Directory of Open Access Journals (Sweden)

    Radoš Aleksandar

    2002-01-01

    Full Text Available Little is known about a Russian photographer, Ivan Groman. His photographic work, originating in 1876 in the Principality of Serbia, was used repeatedly for illustrations, but has never been thoroughly analyzed as a historic document. Although his photographs, kept in the Archives of the City of Belgrade, the Museum of the City of Belgrade, and the Military Museum in Belgrade, may not represent his entire photographic opus, a thorough analysis of his work may serve the purpose of seeking for the message, and therefore for the aim of his work and stay in Belgrade. A small number of his photographs of Belgrade, constituting small series (‘stories’ of a relatively small area, clearly lead to the conclusion that I. V. Groman was not just a photographer – documentarist with an unquestionable and subtle artistic sense, but also a perceptive and possibly experienced “documentarist on a military mission”. It does not diminish the significance and value of his photographic work in Belgrade. Quite the opposite. His opus gains the documentary vigor of the travel journal photo-story, which in its expressiveness does not fall short of the travel journals of a more traditional kind.

    The Johnson Criteria metric calculates probability of detection of an object imaged by an optical system, and was created in 1958 by John Johnson. As understanding of target detection has improved, detection models have evolved to better model additional factors such as weather, scene content, and object placement. The initial Johnson Criteria, while sufficient for technology and understanding at the time, does not accurately reflect current research into target acquisition and technology. Even though current research shows a dependence on human factors, there appears to be a lack of testing and modeling of human variability.

  3. Fourth year medical students’ reflective writing on “death of Ivan Ilych: a qualitative study

    Directory of Open Access Journals (Sweden)

    MAHSHID ZOHOURI

    Full Text Available Introduction: Medical students should be familiar with the end of life ethical issues and its considerations. For teaching end of life care to medical students, literature is a source of excellent narratives of patients with experiences of terminally ill condition in their journey through suffering and one of the most favourite bioethics literature readings has been the death of Ivan Ilych by Tolstoy. We used this novel to show medical students end of life events and suffering and asked them to write a reflective essay on it. We aimed to find what students think about terminally ill patients and their journey to death. Methods: In an inductive qualitative content analysis model, 350 essays, collected by homogenous sampling, were analyzed. The fourth year medical students were provided with the Death of Ivan Ilych novel to read. They were asked to write a reflection essay based on the reflective stages defined by Sandars. These essays served as the unit of analysis, each being read several times and a coding model was formed according to main topics. The related concepts in each unit were named as themes and each theme was abstracted to a code and the related codes were compared and developed as categories. Results: Qualitative content analysis of 350 essays of fourth year medical students revealed three major categories in students’ reflection on reading Death of Ivan Ilych as an end of life human body.

    Introduction: Medical students should be familiar with the end of life ethical issues and its considerations. For teaching end of life care to medical students, literature is a source of excellent narratives of patients with experiences of terminally ill condition in their journey through suffering and one of the most favourite bioethics literature readings has been the death of Ivan Ilych by Tolstoy. We used this novel to show medical students end of life events and suffering and asked them to write a reflective essay on it. We aimed to find what students think about terminally ill patients and their journey to death. Methods: In an inductive qualitative content analysis model, 350 essays, collected by homogenous sampling, were analyzed. The fourth year medical students were provided with the Death of Ivan Ilych novel to read. They were asked to write a reflection essay based on the reflective stages defined by Sandars. These essays served as the unit of analysis, each being read several times and a coding model was formed according to main topics. The related concepts in each unit were named as themes and each theme was abstracted to a code and the related codes were compared and developed as categories. Results: Qualitative content analysis of 350 essays of fourth year medical students revealed three major categories in students’ reflection on reading Death of Ivan Ilych as an end of life human body. These included: 1) Emotional experience, 2) Empathy and effective communication, 3) Spirituality and dignity. Analysis of essays showed that this reflection activity may help medical students have a deeper idea of the end of life situation and feelings.

    1997-01-01

    Count Leo Tolstoy's classic novella The Death of Ivan Ilyich (1886/1981) is examined from the perspective of a health care professional for its portrayal of a helping relationship between the central character and his servant Gerasim. The purpose of the article is to extrapolate helping behaviors depicted in the story and construct a caregiving model. Tolstoy's work, literary critiques of the novel, biographies of Tolstoy, and principles from feminist ethics are used as sources. The model will be of assistance to those who care for the terminally ill.

    Johnson & Johnson Family of Companies introduced its worksite health promotion program in 1979. The program evolved and is still in place after more than thirty years. We evaluated the program's effect on employees' health risks and health care costs for the period 2002-08. Measured against similar large companies, Johnson & Johnson experienced average annual growth in total medical spending that was 3.7 percentage points lower. Company employees benefited from meaningful reductions in rates of obesity, high blood pressure, high cholesterol, tobacco use, physical inactivity, and poor nutrition. Average annual per employee savings were $565 in 2009 dollars, producing a return on investment equal to a range of $1.88-$3.92 saved for every dollar spent on the program. Because the vast majority of US adults participate in the workforce, positive effects from similar programs could lead to better health and to savings for the nation as a whole.

  13. Chronic Conditions: Beckett, Bergson and Samuel Johnson.

    Science.gov (United States)

    Maude, Ulrika

    2016-06-01

    This article analyses the work of the twentieth-century late modernist Samuel Beckett, in light of the turn-of-the-century anti-rationalist Henri Bergson (1859-1941) and the eighteenth-century neoclassicist Samuel Johnson (1709-1784). What unites these three very different thinkers is a concern over habitual, automatic and involuntary behavior, which in all three cases has a distinctly neurological dimension. Beckett's writing explores the Bergsonian notion, informed by medicine and experimental psychology, of the limitations of agency, of "the deep-seated recalcitrance of matter," and of the human as always already inflicted by the mechanical, a fact that is poignantly highlighted by the case of Samuel Johnson. Through his encounter with Johnson, Beckett registers a paradigm shift in the understanding of subjectivity. Whereas Bergson aims, throughout his career, to contest the mechanical, habitual and automatic that threaten to encrust themselves upon the living, in Beckett's often uncannily Johnsonian writing, the habitual and the automatic become progressively more central, until in the late works, habit and mechanical behavior constitute a tenuous, fraught and primitive ontology, the residues of an agential self.

  14. Properties of Codes in the Johnson Scheme

    Silberstein, Natalia

    2010-01-01

    Codes which attain the sphere packing bound are called perfect codes. The most important metrics in coding theory on which perfect codes are defined are the Hamming metric and the Johnson metric. While for the Hamming metric all perfect codes over finite fields are known, in the Johnson metric it was conjectured by Delsarte in 1970's that there are no nontrivial perfect codes. The general nonexistence proof still remains the open problem. In this work we examine constant weight codes as well as doubly constant weight codes, and reduce the range of parameters in which perfect codes may exist in both cases. We start with the constant weight codes. We introduce an improvement of Roos' bound for one-perfect codes, and present some new divisibility conditions, which are based on the connection between perfect codes in Johnson graph J(n,w) and block designs. Next, we consider binomial moments for perfect codes. We show which parameters can be excluded for one-perfect codes. We examine two-perfect codes in J(2w,w) a...

    Full Text Available In this paper, the estimation of pollutant load within the drinking water protection areas (DWPA of springs Sv. Ivan, Bulaž, and Gradole in Northern Istria (Croatia is presented. To estimate the pollution load, the spreadsheet tool for estimating pollutant load (STEPL model was used. STEPL calculates loads of organic pollutants, nutrients, and suspended solids. For each analyzed spring total, specific and pollutant loads by each analyzed category are calculated. The results show that the greatest loads are caused by human activities. In addition, for the purpose of the analysis, two additional future scenarios are introduced; one describes the situation after the implementation of the first phase of the Istrian water protection system project, and the other that describes a possible future state where each agglomeration of over 100 inhabitants within the protected areas has an adequate wastewater treatment plant (WWTP.

    2005-03-01

    The life sciences in the 20th century were guided to a large extent by a reductionist program seeking to explain biological phenomena in terms of physics and chemistry. Two scientists who figured prominently in the establishment and dissemination of this program were Jacques Loeb in biology and Ivan P. Pavlov in psychological behaviorism. While neither succeeded in accounting for higher mental functions in physical-chemical terms, both adopted positions that reduced the problem of consciousness to the level of reflexes and associations. The intellectual origins of this view and the impediment to the study of consciousness as an object of inquiry in its own right that it may have imposed on peers, students, and those who followed is explored.

    Medical practice and the field of humanities frequently intersect. It is uncanny how problems presented or described in literature that are several hundred years old still present themselves to us on a regular basis. Often, our answers to these dilemmas are not perfect, but we continue our attempts at providing solutions through an enlightened evolution of our thought and approaches. Leo Tolstoy's novella, The Death of Ivan Ilych, is a classic piece of literature that allows a view of the dying process in an ordinary human being, and presents us with an opportunity to observe, not only the intersection of medicine and humanities, but also that of critical care and palliative medicine. Here Tolstoy, through his keen observation of the human condition at the end of life, allows us an opportunity to view a 19(th) century perspective that has an all too familiar persistence that needs a 21(st) century intervention.

One among such creators is the architect – Ivan Antić, Member of Academy, who in his design projects and with his distinct architectural credo managed to express the ideals of time in which he was creating. His buildings – masterpieces of the Serbian modern architecture, e.g. Museum of the modern art located at Ušće in Belgrade; Museum for victims of execution in Šumarice sport arenas, public and business edifices, all of them represent unique architectural achievements. Those building forms are both functional and aesthetical, almost as a sublimate in fulfillment of content and construction requirements.

    Full Text Available ABSTRACT Microphysical and thermodynamical features of two tropical systems, namely Hurricane Ivan and Typhoon Conson, and one sub-tropical, Catarina, have been analyzed based on space-born radar PR measurements available on the TRMM satellite. The procedure to classify the reflectivity profiles followed the Heymsfield et al (2000 and Steiner et al (1995 methodologies. The water and ice content have been calculated using a relationship obtained with data of the surface SPOL radar and PR in Rondonia State in Brazil. The diabatic heating rate due to latent heat release has been estimated using the methodology developed by Tao et al (1990. A more detailed analysis has been performed for Hurricane Catarina, the first of its kind in South Atlantic. High water content mean value has been found in Conson and Ivan at low levels and close to their centers. Results indicate that hurricane Catarina was shallower than the other two systems, with less water and the water was concentrated closer to its center. The mean ice content in Catarina was about 0.05 g kg-1 while in Conson it was 0.06 g kg-1 and in Ivan 0.08 g kg-1. Conson and Ivan had water content up to 0.3 g kg-1 above the 0ºC layer, while Catarina had less than 0.15 g kg-1. The latent heat released by Catarina showed to be very similar to the other two systems, except in the regions closer to the center.No presente trabalho foram analisados as características microfísicas e termodinâmicas de dois sistemas tropicais, o Furacão Ivan e o Tufão Conson, e um sub-tropical, Catarina, a partir de medições feitas com o radar PR a bordo do satélite TRMM. Na análise, os perfis de refletividade foram classificados conforme as técnicas de Heymsfield et al (2000 e Steiner et al (1995 e em seguida foram calculados os conteúdos de água e gelo, a partir de uma relação obtida no Estado de Rondônia (Brasil.

    Full Text Available Abstract The aim of this writing is to consider how a certain material dialectic is stated in the so called Mansana de Chinati, a complex built by the sculptor Donald Judd in the city of Marfa, Texas, from 1974 onwards, when  compared with the two houses built by the architect Philip Johnson in his  state of New Canaan, Connecticut, around 1950. Both in New Canaan and in la Mansana de Chinati we find a dialectical  opposition between industrial and handicraft architecture, as both Philip  Johnson and Donald Judd consider that there is a main architecture, where material and industrial techniques are used, and a subordinate or service  architecture which is built with adobe or brick and handicraft techniques. This latter architecture will embody all the qualities associated with poverty, as material abundance or spatial closure. Nevertheless, the exhibition of poverty has not as its definite aim the domestic handicraft buildings, built with adobe or brick, but it will be at the service of that other architecture, built with industrial techniques, that has to give up comfort and wellbeing o at least conceal them in the form of radical austerity.

  4. Johnson Type Bounds on Constant Dimension Codes

    Xia, Shu-Tao

    2007-01-01

    Very recently, an operator channel was defined by Koetter and Kschischang when they studied random network coding. They also introduced constant dimension codes and demonstrated that these codes can be employed to correct errors and/or erasures over the operator channel. Constant dimension codes are equivalent to the so-called linear authentication codes introduced by Wang, Xing and Safavi-Naini when constructing distributed authentication systems in 2003. In this paper, we study constant dimension codes. It is shown that Steiner structures are optimal constant dimension codes achieving the Wang-Xing-Safavi-Naini bound. Furthermore, we show that constant dimension codes achieve the Wang-Xing-Safavi-Naini bound if and only if they are certain Steiner structures. Then, we derive two Johnson type upper bounds, say I and II, on constant dimension codes. The Johnson type bound II slightly improves on the Wang-Xing-Safavi-Naini bound. Finally, we point out that a family of known Steiner structures is actually a fam...

  5. LEGEND, STORY AND NARRATION IN THE GENRE STRUCTURE OF IVAN SHMELEV'S SHORT NOVEL INEXHAUSTIBLE CUP: THE PROBLEM OF SOURCES

    Directory of Open Access Journals (Sweden)

    Nikolay Ivanovich Sobolev

    2013-11-01

    Full Text Available The article is devoted to one of the central episodes of Ivan Shmelev's short novel The Inexhaustible Chalice (Inexaustible Cup, or Non-intoxicating Chalice. The source of this episode was a legend, recorded by a priest Yakov Brilliantov. In 1912 he published the text of the legend calling it a Story of the Miraculous Icon of the Mother of God Called the “Inexhaustible Chalice”. The legend existed in the folk tradition for a long time. The paper presents a hypothesis that Ivan Shmelev reproduced an oral version or edition of the legend in his short novel. Comparison of Shmelev's novel and the old legend reveals similarities and discrepancies of texts, analysis of which can serve as the basis for important observations on lingvopoetics of the short novel and the author’s style. Ivan Shmelev uses the legend as a source of pious history: he connects it with his main text at all narrative levels, while leaving only functional elements in the recipient text. This type of creative editing can be defined as a form of a condensed narrative. Moreover, analysis of sources leads to a conclusion about the poetics of the chronotope and the main characters of the tale.

    2010-12-01

    Full Text Available The aim of this study is to present Albert Camus’ and Karl Jaspers’ interpretations of Ivan Karamazov’s rebellion as the diagnoses of the weakness of the human intellect in confrontation with the world and the criticism of rationalism. Therefore, in the introduction I will present those fragments of the novel that characterize Ivan’s rebellion as highly abstract and theoretical. At the same time, this common literary context serves as the ground for reconstruction and comparison of the basic philosophical assumptions of each author. The intention of the remaining part of the paper is, firstly, to reconstruct A. Camus’ and K. Jaspers’ epistemology and, secondly, to analyse the arguments against Ivan’s attitude formulated by the writers. Their criticisms of the protagonist’s excessive trust in intellect is based on their own concepts of human epistemic capacity, which are related to the problems of the absurd in A. Camus’ and transcendence in K. Jaspers’ writings. The question of nihilism demands analysis of A. Camus’ idea of the nature of rebellion as both affirmative and negative, and of K. Jaspers’ notion of faith as pre-intellectual trust. Finally, their criticisms of the slogan “If there is no God, then anything is allowed” introduces the problem of freedom, which allows the comparison of the concepts of solidarity (A. Camus and communication (K. Jaspers. In the conclusion these two philosophical attitudes are discussed together. Keywords: ; ; ; ; ; ; ; ;

    Full Text Available The article considers one of the aspects of artistic adaptation of an original source in the art works by Ivan Shmelev. The material of article is the story of the Abbot Damaskin, and the poetic text in the essays On the Rocks of Valaam and The Old Valaam, and folklore text in the tale Inexhaustible Cap. The analysis of the genesis of the formal structure of the quotes of diff erent levels at diff erent stages of the history of essays reveals the author's intention to recreate the Russian Orthodox world, to show examples of prime examples of ascetic life. To this end, the author transforms the text of the Early edition, leaving only those fragments that create images of Holiness. In the Later edition of the concise description, the author uses a reportage style. He accurately reproduces the discoerse of the monks. Analysis of the specificity of adaptation wedding ritual songs in the narrative structure of the novel shows that the author changes the value of the folklore text. Creates a parallel of the ecclesiastical and the folk, refl ecting the ethno-religious attitude of the main character. Author`s intention is to see and understand the Christian soul of the Russian people.

    Summary The founder of physiology studies in the Balkans and the pioneer of research on hypothermia, Ivan Djaja (Jean Giaja) was born 1884 in L’Havre. Giaja gained his PhD at the Sorbonne in 1909. In 1910 he established the first Chair of Physiology in the Balkans and organized the first Serbian Institute for Physiology at the School of Philosophy of the University of Belgrade. He led this Institute for more than 40 subsequent years. His most notable papers were in the field of thermoregulation and bioenergetics. Djaja became member of the Serbian and Croatian academies of science and doctor honoris causa of Sorbonne. In 1952 for the seminal work on the behaviour of deep cooled warm blooded animals he becane associate member of the National Medical Academy in Paris. In 1955 the French Academy of Sciences elected him as associate member in place of deceased Sir Alexander Fleming. Djaja died in 1957 during a congress held in his honour. He left more than 200 scientific and other papers and the golden DaVincian credo “Nulla dies sine experimento”. His legacy was continued by several generations of researchers, the most prominent among them being Stefan Gelineo, Radoslav Andjus and Vojislav Petrović. PMID:21777022

Na segunda crítica social da saúde, Illich trata do surgimento de uma nova iatrogênese social, a iatrogênese do corpo, que resulta de uma espécie de obsessão com a saúde corporal e com sua produção através de atividades físicas, dietas etc. em aparente condição de autonomia. Trata-se de um consumismo do corpo saudável, que responde menos à ação dos médicos e mais às informações difundidas pelos meios de comunicação e pelos agentes terapêuticos não-oficiais.

In 1893 his family emigrated to the United States of America, first to Ely, Calumet, Cleveland and then to some other American towns. After a brief return to Slovenia in 1898/9, where Zorman attended elementary school in Velesovo near Kranj, they finally settled down in 1904 in Cleveland. In 1907 Zorman took up the study of modern languages (English, French and Italian, history and music at Western Reserve University and graduated only in music in 1912. For a number of years, during 1908 and 1956, he was chief organist and choir leader (like his father at the parish church of Sv. Lovrenc in Newburgh near Cleveland. During 1920 and 1925 he was professional director of the "Zorman Philharmonic". Not only was he known as a musician, he was very much present in the public life of the Slovene community living in Cleveland, as the enthusiastic teacher of Slovene literature in the Slovene school of the "Slovenski narodni dom", as a poet, translator and public speaker.

    This article critically assesses the ideology of industrialism in light of Ivan Illich's Medical Nemesis. The paper is divided into three sections. The first section is a description of the main features of that ideology, the most prevalent and influential one used in sociological literature to explain the state both of Western societies and of our health services. Also in this section, it is shown how these features appear in Illich's analysis of our societies, of our health services, and of the different clinical, social, and structural iatrogeneses that health services create. The second section examines the assumptions underlying Illich's analysis and discusses their validity to explain the nature and function of our Western health services and their iatrogenic effects. Where Illich's explanations are considered invalid, alternative explanations are presented. Among them, it is postulated that it is not industrialism, but the assumedly transcended category of capitalism that is the cause of the social and structural iatrogeneses. The third section discusses the political implications of Illich's analysis, in a moment when our Western societies are supposedly in crisis.

  15. The politics of physiological psychology. Ivan Pavlov's suppressed defense of scientific freedom and its consequences.

    This statement, first presented at a plenary session of the Pavlovian Society on 9 October 1992, in Los Angeles, California, attempts to assess the recently released speech delivered by Ivan Pavlov in 1923, but publicly brought to light only in 1991, on the subject of "Communist Dogmatism and the Autonomy of Science." This speech, noteworthy for the courage of the delivery under adverse circumstances no less than the contents of its remarks, compels a new estimate of the place of science in a totalitarian system boasting an ideology of physiological psychology. It also sheds new light on the Russian Nobel laureate and pioneer in the areas of behavior modification induced by the functions of the higher nervous system. These remarks take an in-depth view of American radical and Marxian appraisals--how they followed the Soviet lead in harnessing Pavlov to the Communist cause, and in attempting to discredit the work of Sigmund Freud. This lethal combination of Communist political needs and ideological proclivities served to rationalize the implementation of slave labor as work therapy during the Stalinist era. The linkage of Pavlov to Makarenko in education and Michurin in biology serves as a case study in the manufacture of tradition. The collapse of the Soviet system permits a recasting of the history of science and Pavlov's place in Russian life. Such new conditions also provide a lesson in the distortive role of ideology in the evolution of modern science.

    Stevens-Johnson syndrome and toxic epidermal necrolysis are two serious immune diseases within the context of bullous mucocutaneous syndrome. These have varying degrees of involvement of the skin and usually at least two mucous membranes. Three clinical cases are presented, two of them with significant ophthalmological sequelae, who had received drug treatment as a possible trigger, and another milder clinical case caused by Mycoplasma pneumoniae. The ophthalmologist plays a crucial role in the outcome and eye care of the patient in order to try to avoid the appearance of sequelae and subsequent loss of vision.

    Approximately 10% of the world's coastline consists of low-lying barrier coasts, which are susceptible to coastal flooding, dune overwash and breaching. Although several numerical cross shore models exist to calculate beach and dune profile change during storms, overwash and breaching are not necessarily incorporated. Additionally, these models assume longshore uniformity and therefore do not include longshore variation in for instance dune height, shoreline angle and wave conditions. In order to simulate overwash on a barrier island we use a new numerical model for the nearshore and coast called XBeach (Roelvink et al., ICCE 2008). This process-based and time dependent model solves coupled short and long wave propagation, sediment transport and morphology in 2DH. The model has a robust numerical scheme, allowing it to simulate flooding and drying, thereby removing the need for separate dry and wet domains and procedures. XBeach is used to model a section of Santa Rosa Island, Florida, during Hurricane Ivan in 2004. This island was heavily overwashed during the hurricane and breached in one location. The model is set-up using high resolution airborne LIDAR altimetry and bathymetry data and forced using surge and wave data from larger scale numerical models. The modelled final bed elevation is compared to airborne LIDAR data acquired three days after the storm. The results show that XBeach is capable of simulating the complex hydrodynamics that occur during extreme overwash events. It is shown that the model can recreate the morphological developments that occurred on the island during the storm and that the model has considerable quantitative skill in predicting the final bed elevation.

    Purpose To describe changes in intraocular pressure (IOP) in the ‘alternative treatments to Inhibit VEGF in Age-related choroidal Neovascularisation (IVAN)’ trial (registered as ISRCTN92166560). Design Randomised controlled clinical trial with factorial design. Participants Patients (n=610) with treatment naïve neovascular age-related macular degeneration were enrolled and randomly assigned to receive either ranibizumab or bevacizumab and to two regimens, namely monthly (continuous) or as needed (discontinuous) treatment. Methods At monthly visits, IOP was measured preinjection in both eyes, and postinjection in the study eye. Outcome measures The effects of 10 prespecified covariates on preinjection IOP, change in IOP (postinjection minus preinjection) and the difference in preinjection IOP between the two eyes were examined. Results For every month in trial, there was a statistically significant rise in both the preinjection IOP and the change in IOP postinjection during the time in the trial (estimate 0.02 mm Hg, 95% CI 0.01 to 0.03, p<0.001 and 0.03 mm Hg, 95% CI 0.01 to 0.04, p=0.002, respectively). There was also a small but significant increase during the time in trial in the difference in IOP between the two eyes (estimate 0.01 mm Hg, 95% CI 0.005 to 0.02, p<0.001). There were no differences between bevacizumab and ranibizumab for any of the three outcomes (p=0.93, p=0.22 and p=0.87, respectively). Conclusions Anti-vascular endothelial growth factor agents induce increases in IOP of small and uncertain clinical significance. Trial registration number ISRCTN92166560. PMID:27073205

    Full Text Available Dubin-Johnson syndrome (DJS is a rare autosomal recessive disease caused by deficiency of the canalicular multi-specific organic anionic transporter (CMOAT protein. The consequent impairment of conjugated bilirubin secretion into the bile results in hyperbilirubinemia, and the manifestation is black pigment depositing in liver cells under microscope and black liver from macroscopy. However, DJS appears to be a benign disease and no specific treatment has been developed. Misdiagnosis of DJS is common and patients frequently experience repeated visits to physicians during which they undergo a battery of unnecessary clinical testing. This situation may be further complicated by concomitant diseases, which are only recently being recognized and may be the primary etiology or a promoting factor for the patient’s prolonged jaundice. Moreover, the patients who tend to present to clinic during middle and old age which is the rare morbidity age can be easily misdiagnosed. As the disease can be easily ignored. In this review, we summarize the known information regarding DJS pathogenesis, clinical characteristics, and diagnostic methods in order to improve physicians’ awareness of the disease.

    2014-01-01

    NASA's Johnson Space Center has implemented a great number of renewable energy systems. Renewable energy systems are necessary to research and implement if we humans are expected to continue to grow and thrive on this planet. These systems generate energy using renewable sources - water, wind, sun - things that we will not run out of. Johnson Space Center is helping to pave the way by installing and studying various renewable energy systems. The objective of this report will be to examine the completed renewable energy projects at NASA's Johnson Space Center for a time span of ten years, beginning in 2003 and ending in early 2014. This report will analyze the success of each project based on actual vs. projected savings and actual vs. projected efficiency. Additionally, both positive and negative experiences are documented so that lessons may be learned from past experiences. NASA is incorporating renewable energy wherever it can, including into buildings. According to the 2012 JSC Annual Sustainability Report, there are 321,660 square feet of green building space on JSC's campus. The two projects discussed here are major contributors to that statistic. These buildings were designed to meet various Leadership in Energy and Environmental Design (LEED) Certification criteria. LEED Certified buildings use 30 to 50 percent less energy and water compared to non-LEED buildings. The objectives of this project were to examine data from the renewable energy systems in two of the green buildings onsite - Building 12 and Building 20. In Building 12, data was examined from the solar photovoltaic arrays. In Building 20, data was examined from the solar water heater system. By examining the data from the two buildings, it could be determined if the renewable energy systems are operating efficiently. Objectives In Building 12, the data from the solar photovoltaic arrays shows that the system is continuously collecting energy from the sun, as shown by the graph below. Building 12

However, Deschooling Society is but one of many aspects in the overall set of criticisms Illich constructed regarding education and its institutions throughout his entire career. With this matter in mind, this article presents a study on the usefulness of Illich’s thoughts on education and its institutions in the debate on the «post-2015 agenda» being promoted by organisations such as UNESCO and the World Bank.

    On November 19, 2011, Norine G. Johnson, the ninth woman to serve as president of the American Psychological Association (APA), lost a valiant battle with cancer. Norine's curiosity about her grandmother's strength led to much of her later work on the development of strength and resiliency in adolescent girls and in women. She received her doctorate in 1972, with a minor in child development, and she became one of the first to be considered a pediatric psychologist, a newly emerging specialty. Norine became involved in organized psychology as her children got older. When she learned there had not been a woman president of the Massachusetts Psychological Association (MPA) for almost 50 years, she was appalled. An ardent feminist, who had served on MPA's Board of Directors, she could not let the situation remain that way. She ran for president and won, serving from 1981 to 1983, and then mentored many women colleagues into the role. MPA sent her to the Council of the APA as one of their representatives, and she immediately ran for a seat on the Finance Committee, later serving as chair of the committee. During her tenure on the Finance Committee, she helped create financial policy that changed APA from an organization whose assets were threatened and shrinking to a financially solid association. Norine considered Division 35 (Psychology of Women) to be her home in APA, a place filled with warmth, collegiality, and shared values. She and Judith Worell spearheaded the extremely important and successful 1993 National Conference on Education and Training in Feminist Practice. Norine was elected to the APA Board of Directors in 1997, where she served with distinction, continuing to focus on the financial well-being of the Association. Not surprisingly, she went from that role to being elected APA president. Her focus as president was on the changes in the health care delivery system in the United States. She was a staunch champion of the biopsychosocial model of health

    Full Text Available It has often been claimed that Frances Burney (1752-1840 was influenced linguistically by Samuel Johnson (1709-1784. Sorensen (1969: 390, and others with him, have even called her a "slavish imitator" of the language which Johnson used in his Rambler essays. Although far from simple guesswork, quantitative studies such as Sorensen's remain impressionistic, which makes it difficult to incorporate his (and similar observations in quantitative socio-histoncal linguistic studies of the English language. In the present study, the question whether Burney was indeed a serious imitator of Johnson's usage is answered by looking at the problem from a quantitative rather than qualitative perspective, and addressed within the framework of histoncai social network analysis.

    When compiling the Dictionary of the English Language, Johnson read and annotated over two hundred thousand passages from innumerable English authors of various disciplines across four centuries. Most of the literary anecdotes came from Shakespeare, Milton, Dryden and Pope. The medical and scientific anecdotes came from 31 scientists, physicians, pharmacologists and surgeons. This reflects Johnson's admiration for science and its benefit to the public. He told Boswell, 'Why Sir, if you have but one book with you upon a journey let it be a book of science. When you read through a book of entertainment, you know it, and it can do no more for you, but a book of science is inexhaustible'.

    Hyperbilirubinemia has been presumed to prevent the process of atherogenesis and cancerogenesis mainly by decreasing oxidative stress. Dubin-Johnson syndrome is a rare, autosomal recessive, inherited disorder characterized by biphasic, predominantly conjugated hyperbilirubinemia with no progression to end-stage liver disease. The molecular basis in Dubin-Johnson syndrome is absence or deficiency of human canalicular multispecific organic anion transporter MRP2/cMOAT caused by homozygous or compound heterozygous mutation(s) in ABCC2 located on chromosome 10q24. Clinical onset of the syndrome is most often seen in the late teens or early adulthood. In this report, we describe a case of previously unrecognized Dubin-Johnson syndrome caused by two novel pathogenic mutations (c.2360_2366delCCCTGTC and c.3258+1G>A), coinciding with cholestatic liver disease in an 82-year-old male patient. The patient, suffering from advanced atherosclerosis with serious involvement of coronary arteries, developed colorectal cancer with nodal metastases. The subsequent findings do not support the protective role of Dubin-Johnson type hyperbilirubinemia.

    The RGB Bayer filter system consists of a mosaic of R, G, and B filters on the grid of the photo sensors which typical commercial DSLR (Digital Single Lens Reflex) cameras and CCD cameras are equipped with. Lot of unique astronomical data obtained using an RGB Bayer filter system are available, including transient objects, e.g. supernovae, variable stars, and solar system bodies. The utilization of such data in scientific research requires that reliable photometric transformation methods are available between the systems. In this work, we develop a series of equations to convert the observed magnitudes in the RGB Bayer filter system (RB, GB, and BB) into the Johnson-Cousins BVR filter system (BJ, VJ, and RC). The new transformation equations derive the calculated magnitudes in the Johnson-Cousins filters (BJcal, VJcal, and RCcal) as functions of RGB magnitudes and colors. The mean differences between the transformed magnitudes and original magnitudes, i.e. the residuals, are (BJ - BJcal) = 0.064 mag, (VJ - VJcal) = 0.041 mag, and (RC - RCcal) = 0.039 mag. The calculated Johnson-Cousins magnitudes from the transformation equations show a good linear correlation with the observed Johnson-Cousins magnitudes.

    Full Text Available Teorii și practice ale integrării europene [Theories and Practices of European Integration] is a genuine contribution to understanding how the European Union’s particular character has been adjusted in more than half of century of institutional growth and development. Professor Ivan`s key argument for this book is that the European Union has been shaped as a functional project taking into consideration the diverse heritage and traditions of its Member States. The opening chapter of this book focuses on the particularities of international relations discipline after the Second World War in order to introduce the theme of European Integration Process. This chapter must be analysed in a series of contributions dedicated to the European Integration process and to the theories that made this integration possible because professor Ivan has previously published books such as: Statele Unite ale Europei [The United States of Europe], Sub zodia Statelor Unite ale Europei [Under the Sign of the United States of Europe], in which he debates the origins of the European construction and brings forward arguments to support the importance of each theoretical and functional pillar of this “Common European Project”.

    Stonewall, Adam J.; Beal, Benjamin A.

    2017-04-14

    Digital flood-inundation maps were created for a 12.9‑mile reach of Johnson Creek by the U.S. Geological Survey (USGS). The flood-inundation maps depict estimates of water depth and areal extent of flooding from the mouth of Johnson Creek to just upstream of Southeast 174th Avenue in Portland, Oregon. Each flood-inundation map is based on a specific water level and associated streamflow at the USGS streamgage, Johnson Creek at Sycamore, Oregon (14211500), which is located near the upstream boundary of the maps. The maps produced by the USGS, and the forecasted flood hydrographs produced by National Weather Service River Forecast Center can be accessed through the USGS Flood Inundation Mapper Web site (http://wimcloud.usgs.gov/apps/FIM/FloodInundationMapper.html).Water-surface elevations were computed for Johnson Creek using a combined one-dimensional and two‑dimensional unsteady hydraulic flow model. The model was calibrated using data collected from the flood of December 2015 (including the calculated streamflows at two USGS streamgages on Johnson Creek) and validated with data from the flood of January 2009. Results were typically within 0.6 foot (ft) of recorded or measured water-surface elevations from the December 2015 flood, and within 0.8 ft from the January 2009 flood. Output from the hydraulic model was used to create eight flood inundation maps ranging in stage from 9 to 16 ft. Boundary condition hydrographs were identical in shape to those from the December 2015 flood event, but were scaled up or down to produce the amount of streamflow corresponding to a specific water-surface elevation at the Sycamore streamgage (14211500). Sensitivity analyses using other hydrograph shapes, and a version of the model in which the peak flow is maintained for an extended period of time, showed minimal variation, except for overbank areas near the Foster Floodplain Natural Area.Simulated water-surface profiles were combined with light detection and ranging (lidar

    Water quality of streams in Johnson County, Kansas was evaluated from October 2002 through December 2007 in a cooperative study between the U.S. Geological Survey and the Johnson County Stormwater Management Program. Water quality at 42 stream sites, representing urban and rural basins, was characterized by evaluating benthic macroinvertebrates, water (discrete and continuous data), and/or streambed sediment. Point and nonpoint sources and transport were described for water-quality constituents including suspended sediment, dissolved solids and major ions, nutrients (nitrogen and phosphorus), indicator bacteria, pesticides, and organic wastewater and pharmaceutical compounds. The information obtained from this study is being used by city and county officials to develop effective management plans for protecting and improving stream quality. This fact sheet summarizes important results from three comprehensive reports published as part of the study and available on the World Wide Web at http://ks.water.usgs.gov/Kansas/studies/qw/joco/ .

  9. A semiotic interpretation of national typology: the English, the Boers and ... the Russians (Ivan Goncharov’s Frigate Pallas

    1991-05-01

    Full Text Available This article examines the text of renowned nineteenth century Russian travellers notes, The Frigate Pallada, by Ivan Goncharov, the author of Oblomov. Using the teachings of Victor Shklovsky, Yurij Tynianov and Yurij Lotman on the role of the genre of travellers notes in the history of Russian literature, the author examines the chapter on the Cape Province. She demonstrates that in his descriptions of the two nations of the Cape Province - the English and the Boers - Goncharov is applying that which is known to him - his own cultural model of the Russian society of the mid-nineteenth century. In his examination of differences between the English and the Boers Goncharov applies the ideological dichotomy between the Slavophiles and the Westernisers. Goncharov, by "inverting" the "dual model of Russian culture" (Lotman & Uspensky, 1984a draws comparisons between the Russians of the Oblomov Slavophile type on the one hand, and the English on the other hand as the model for the improvement of the industry of the economically backward Russian nation. To Goncharov the Boers resemble the Oblomov, old world side of dichotomy, which by inversions of the dual model can fluctuate between "the good" and "the bad" categories.

    Elevated serum level of bilirubin is a common manifestation which is occurred in several diseases. Hyperbilirubinemia can manifest either conjugated or unconjugated. Conjugated or direct hyperbilirubinemia usually are caused by hepatocellular diseases or cholestatic liver diseases. Merely conjugated hyperbilirubinemia is the main manifestation of two congenital syndromes, including Dubin-Johnson and rotor syndrome; however it can be seen in some patients with recurrent benign intrahepatic cholestasis. This article reports a patient with Dubin- Johuson syndrome as a benign and rare condition.

    Evaluation of Johnson and Toshach method to predict fetal weight. 200 patients with terminal pregnancy. The clinical method of Johnson and Toshach was used to calculate the fetal weight and it was compared with the immediate neonatal weight. Results were analyzed by the t Student test for paired data, with a certainty interval of 95%. The technique was accepted as useful in the cases without significative differences. 150 cases (75%) were in labor. The gestational ages were 38 weeks in 62 case; 39 weeks, 56 case; 40 weeks, 60 cases; 41 weeks, 22 cases. The average fetal weight vs neonatal weight was: At 38 weeks, 3,164 g (DS 289 g) vs 3,218 g (DS 364 g) (p > 0.05); 39 weeks 3,175 g (DS 301 g) vs 3,326 g (DS 391 g) (p 0.05). From the cases with significative difference, 85% had labor. The Johnson and Toshach method is useful to predict the fetal weight in patients with terminal pregnancy and no labor.

    Temperature is a key process variable at any nuclear power plant (NPP). The harsh reactor environment causes all sensor properties to drift over time. At the higher temperatures of advanced NPPs the drift occurs more rapidly. The allowable reactor operating temperature must be reduced by the amount of the potential measurement error to assure adequate margin to material damage. Johnson noise is a fundamental expression of temperature and as such is immune to drift in a sensor s physical condition. In and near core, only Johnson noise thermometry (JNT) and radiation pyrometry offer the possibility for long-term, high-accuracy temperature measurement due to their fundamental natures. Small, Modular Reactors (SMRs) place a higher value on long-term stability in their temperature measurements in that they produce less power per reactor core and thus cannot afford as much instrument recalibration labor as their larger brethren. The purpose of this project is to develop and demonstrate a drift free Johnson noise-based thermometer suitable for deployment near core in advanced SMR plants.

    The MORSE code is a large general-use multigroup Monte Carlo code system. Although no claims can be made regarding its superiority in either theoretical details or Monte Carlo techniques, MORSE has been, since its inception at ORNL in the late 1960s, the most widely used Monte Carlo radiation transport code. The principal reason for this popularity is that MORSE is relatively easy to use, independent of any installation or distribution center, and it can be easily customized to fit almost any specific need. Features of the MORSE code are described.

    2011-08-01

    Dubin-Johnson syndrome is a chronic, benign, intermittent jaundice, mostly of conjugated hyperbilirubinemia. The level of bilirubin is not expected to be more than 20 mg/dl in this syndrome. In this article, we report a patient who was evaluated for hyperbilirubinemia and liver function test abnormalities and diagnosed with Dubin-Johnson syndrome coexisting with hereditary spherocytosis. We suggest that other diseases should be investigated if patients with Dubin-Johnson syndrome present with severe hyperbilirubinemia. Dubin-Johnson syndrome accompanied by hemolytic diseases might also have high coproporphyrin levels (as in Rotor's syndrome) than expected in pure Dubin-Johnson syndrome.

    Transition probabilities governing the interaction of energy packets and matter are derived that allow Monte Carlo NLTE transfer codes to be constructed without simplifying the treatment of line formation. These probabilities are such that the Monte Carlo calculation asymptotically recovers the local emissivity of a gas in statistical equilibrium. Numerical experiments with one-point statistical equilibrium problems for Fe II and Hydrogen confirm this asymptotic behaviour. In addition, the re...

    2000-01-01

    The talk presents a brief background on defInitions of catalysis and effects associated with chemically nonequilibrium and low-density flows of aerospace interest. Applications of catalytic recombination on surfaces in dissociated flow are given, including aero heating on reentry spacecraft thermal protection surfaces and reflection of plume flow on pressure distributions associated with the space station. Examples include aero heating predictions for the X-38 test vehicle, the inlet of a proposed gas-sampling probe used in high enthalpy test facilities, and a parabolic body at angle of attack. The effect of accommodation coefficients on thruster induced pressure distributions is also included. Examples of tools used include simple aero heating formulas based on boundary layer solutions, an engineering approximation that uses axisymmetric viscous shock layer flow to simulate full three dimensional flow, full computational fluid dynamics, and direct simulation Monte-Carlo calculations. Methods of determining catalytic recombination rates in arc jet flow are discus ed. An area of catalysis not fully understood is the formation of single-wall carbon nanotubes (SWNT) with gas phase or nano-size metal particles. The Johnson Space Center is making SWNTs using both a laser ablation technique and an electric arc vaporization technique.

    2014-02-22

    This article reviews the contributions of Ivan Michailovich Sechenov [1829-1905] to the neurophysiological concept of central inhibition. He first studied this concept in the frog and on himself. Later his trainees extended the study of central inhibition to other mammalian species. Outside his own country, Sechenov is better known for his prescient contributions to physiological psychology. In Russia, however, he is also revered as "the father of Russian physiology," because of his contributions to neurophysiology and other aspects of physiology including blood gases and respiration, the physiology and biomechanics of movement, and general physiology concepts that appeared in his textbooks and later works he helped translate from largely German sources. After graduation from Moscow University Medical School in 1856 he spent 3½ years in Germany and Austria where he attended lectures and conducted research under the direction of several prominent physiologists and biochemists. In his subsequent academic career he held positions at universities in St. Petersburg (1860-1870; 1876-1888), Odessa (1871-1876) and Moscow (1890-1905). From 1860 onwards he was acclaimed as a physiologist in academic circles. He was also well known in Russian society for his public lectures on physiology and his views on physiological psychology. The latter resulted in him being branded "politically unreliable" by the tsarist bureaucracy from 1863 onwards. Sechenov's first (1862) study on central inhibition remains his most memorable. He delayed the withdrawal of a frog's foot from a weak acid solution by chemical or electrical stimulation of selected parts of the central nervous system. He also noted similar effects on his own hand during co-activation of other sensory inputs by tickling or teeth gnashing.

In June 1990 streptococcal pharyngitis, fever (38.8-39,9 degrees C) were registered. Penicillin was given. Next day bullous lesions on lips, left ear, trunk and lower extremities and vesiculose lesions with a wide, erythematose base ("iris") and then conjuctivitis were registered. Laboratory tests: SR70.; Leu - 11,0; anti-herpes Ab IgG 1/64, IgM 1/8. Stevens-Johnson was diagnosed. There was a recidivation two years after - oral lesions followed by necrosis and bleeding, after half a year a second recidivation with spreading of bullous and vesiculous lesions to penis gland with prepuce of the penis. Last recidivation in February 1993. Anamnesis: Viral meningitis in 1988. mother suffers from herpes labialis. Peripheral blood immunophenotiping lymphocite extremly indicated decreasing values of B Ly, NK and IL-2R+ cells. Bacteriological tests showed an increase of anti-Chlamidia Ab titer (IgG 1/128, IgA and IgM +). In virological testing there was no increase of titer of Abs against viral antigens (Herpes simplex virus, Varicella-Zoster virus, Citomegalovirus, Adenovirus). We conclude that Stevens-Johnson Sy to be diagnosed by characteristic clinical features, aspecialy by frequent reccurences. Immunological testing during the last recidivation showed that parameters of humoral immune reactivity were within normal ranges while revealed defects of cellular immune reactivity cannot elucidate the ethiopathogenesis of this disease.

  5. Stevens-Johnson syndrome complicating adalimumab therapy in Crohn's disease

    The anti-tumor necrosis factor (TNF)a medications demonstrate efficacy in the induction of remission and its maintenance in numerous chronic inflammatory conditions. With the increasing number of patients receiving anti-TNFa agents, however, less common adverse reactions will occur. Cutaneous eruptions complicating treatment with an anti-TNFa agent are not uncommon, occurring in around 20% of patients. Adalimumab, a fully humanized antibody against TNFa, may be expected to cause minimal immune-mediated skin reactions compared to the chimeric monoclonal antibody, infliximab. We, however, report a case of Stevens-Johnson syndrome that required hospitalization and cessation of adalimumab in a patient with Crohn's disease (CD). In this case report, a 29-year-old male with colonic and perianal CD with associated erythema nodosum and large joint arthropathy developed severe mucositis, peripheral rash and desquamation, fevers and respiratory symptoms concomitant with a second dose of 40 mg adalimumab after a 2 mo break from adalimumab therapy. Skin biopsies of the abdominal wall confirmed erythema multiforme and the patient was on no other drugs and infective etiologies were excluded. The patient responded rapidly to IV hydrocortisone and was able to be commenced on infliximab without recurrence of the Stevens-Johnson syndrome. Desquamating skin reactions have now been described in three of the TNFa antagonists (infliximab, etanercept and adalimumab). These reactions can be serious and prescribers need to be aware of the potential mucocutaneous side effects of these agents, especially as Stevens-Johnson syndrome is associated with significant morbidity and mortality.

    Certain individuals who want to change their homosexual preference can be helped by a short-term intensive intervention adapted from the Masters and Johnson model for treating heterosexual disorders. Pretreatment counseling aims at improving the patient's dating, sexual, and intimacy skills; creative problem solving; and stress management. Then for 2 weeks the patient and an opposite-sex partner, living in social isolation, meet daily with a therapy team to address fears and anxieties about intimacy as they arise. The directive psychotherapy format alternates between confrontation of maladaptive belief systems and patterns of relating and support for finding new ways of coping that foster a positive self-image.

    Let $P$ be a set of $n$ points in general position in the plane. A subset $I$ of $P$ is called an \\emph{island} if there exists a convex set $C$ such that $I = P \\cap C$. In this paper we define the \\emph{generalized island Johnson graph} of $P$ as the graph whose vertex consists of all islands of $P$ of cardinality $k$, two of which are adjacent if their intersection consists of exactly $l$ elements. We show that for large enough values of $n$, this graph is connected, and give upper and lower bounds on its diameter.

    At NASA Johnson Space Center (JSC), the Chief Knowledge Officer has been developing the JSC Taxonomy to capitalize on the accomplishments of yesterday while maintaining the flexibility needed for the evolving information environment of today. A clear vision and scope for the semantic system is integral to its success. The vision for the JSC Taxonomy is to connect information stovepipes to present a unified view for information and knowledge across the Center, across organizations, and across decades. Semantic search at JSC means seemless integration of disparate information sets into a single interface. Ever increasing use, interest, and organizational participation mark successful integration and provide the framework for future application.

    Rabey, I M; Hinds, E A; Sauer, B E

    2016-01-01

    We describe a parallel pair of high voltage electric field plates designed and constructed to minimise magnetic Johnson noise. They are formed by laminating glass substrates with commercially available polyimide (Kapton) tape, covered with a thin gold film. Tested in vacuum, the outgassing rate is less than $5\\times10^{-5}$ mbar.l/s. The plates have been operated at electric fields up to 8.3 kV/cm, when the leakage current is at most a few hundred pA. The design is discussed in the context of a molecular spin precession experiment to measure the permanent electric dipole moment of the electron.

    2011-01-01

    Full Text Available Starting with the zero-square “zeon algebra,” the connection with permanents is shown. Permanents of submatrices of a linear combination of the identity matrix and all-ones matrix lead to moment polynomials with respect to the exponential distribution. A permanent trace formula analogous to MacMahon's master theorem is presented and applied. Connections with permutation groups acting on sets and the Johnson association scheme arise. The families of numbers appearing as matrix entries turn out to be related to interesting variations on derangements. These generalized derangements are considered in detail as an illustration of the theory.

    1987-01-01

    The role of affirmative actions is investigated as an interventionist Organization Development (OD) strategy for insuring equal opportunities at the NASA/Johnson Space Center. In doing so, an eclectic and holistic model is developed for the recruiting and hiring of minorities and females over the next five years. The strategy, approach, and assumptions for the model are quite different than those for JSC's five year plan. The study concludes that Organization development utilizing affirmative action is a valid means to bring about organizational change and renewal processes, and that an eclectic model of affirmative action is most suitable and rational in obtaining this end.

    Computer modeling has become useful as an investigative tool and as a client communication and explanation tool in the field of acoustical consulting. A variety of in-house developed and commercially available applications is in constant use at the firm of Wrightson, Johnson, Haddon & Williams. Examples likely to be demonstrated (depending on time) include use of digital filtering for building exterior noise reduction comparisons, a shell isolation rating (SIR) model, simple sound barrier programs, an HVAC spreadsheet, a visual sightline modeling tool, specular sound reflections in a semicircular arc, and some uses of CATT-acoustic auralizations.

  14. Novel Quantum Monte Carlo Approaches for Quantum Liquids

    Rubenstein, Brenda M.

    the eventual hope is to apply this algorithm to the exploration of yet unidentified high-pressure, low-temperature phases of hydrogen, I employ this algorithm to determine whether or not quantum hard spheres can form a low-temperature bcc solid if exchange is not taken into account. In the final chapter of this thesis, I use Path Integral Monte Carlo once again to explore whether glassy para-hydrogen exhibits superfluidity. Physicists have long searched for ways to coax hydrogen into becoming a superfluid. I present evidence that, while glassy hydrogen does not crystallize at the temperatures at which hydrogen might become a superfluid, it nevertheless does not exhibit superfluidity. This is because the average binding energy per p-H2 molecule poses a severe barrier to exchange regardless of whether the system is crystalline. All in all, this work extends the reach of Quantum Monte Carlo methods to new systems and brings the power of existing methods to bear on new problems. Portions of this work have been published in Rubenstein, PRE (2010) and Rubenstein, PRA (2012) [167;169].

    NASA has a rich history of scientific research that has been conducted throughout our numerous manned spaceflight programs. This scientific research has included animal test subjects participating in various spaceflight missions, including most recently, Space Shuttle mission STS-131. The Animal Care Program at Johnson Space Center (JSC) in Houston, Texas is multi-faceted and unique in scope compared to other centers within the agency. The animal care program at JSC has evolved from strictly research to include a Longhorn facility and the Houston Zoo's Attwater Prairie Chicken refuge, which is used to help repopulate this endangered species. JSC is home to more than 300 species of animals including home of hundreds of white-tailed deer that roam freely throughout the center which pose unique issues in regards to population control and safety of NASA workers, visitors and tourists. We will give a broad overview of our day to day operations, animal research, community outreach and protection of animals at NASA Johnson Space Center.

  16. Dialéctica material Donald Judd y Philip Johnson

    2016-05-01

    Full Text Available Resumen El objetivo de este escrito es examinar cómo se plantea una cierta dialéctica material en el conjunto llamado la Mansana de Chinati, construido por el escultor Donald Judd en la ciudad de Marfa, Texas, a partir del año 1974, comparándolo con las dos viviendas que realiza el arquitecto Philip Johnson en su propiedad de New Canaan, Connecticut, en torno al año 1950. Tanto en New Canaan como en la Mansana de Chinati existe una  oposición, una dialéctica, entre una arquitectura industrial y otra artesana, tanto Philip Johnson como Donald Judd consideran que existe una arquitectura principal, la realizada con materiales y técnicas industriales, y otra subalterna o de servicio, la construida con piezas de arcilla y técnicas artesanales. Esta segunda arquitectura encarnará las cualidades asociadas con la pobreza, la abundancia material y la clausura espacial. Sin  embargo, esta exhibición de pobreza no tiene como fin los propios edificios domésticos construidos artesanalmente, ya sea con adobe o con ladrillo, sino que estará al servicio de esa otra arquitectura, construida con técnicas industriales, a la que se exige renunciar a la comodidad y el confort o cuando menos ocultarlos bajo la forma de una radical austeridad.

  17. Paradise and Politics in the Music of Blind Willie Johnson

    Directory of Open Access Journals (Sweden)

    Owen Coggins

    2012-05-01

    Full Text Available I investigate the politics of paradises in the 1920s African-American gospel blues of Blind Willie Johnson. His recordings are apocalyptic vignettes which juxtapose and conflate paradises, using many different voices. I describe the theological and political paradises in Johnson’s songs: the Old Testament journey to Canaan; the post-death heaven in the New Testament; Christ’s kingdom on earth in Revelation; freedom in Northern cities or Canada; and a utopian dream of political emancipation of African-Americans and transformation of society in the South. I outline the various voices present in Johnson’s recordings: vocal styles; accompanying singers; the guitar; grammatical, textual and lexical voices; and the silent voices of technology and time. I suggest traces of a subtle political activism in these voices and paradises, and explore uses of these voices in linking paradises, arguing that the complex transitions enhance the force of signification and frustrate attempts to finalise meanings. Many interpretations of Johnson’s recordings, however, seek to determine final meaning, and I discuss the limitations of such attempts, limitations which not only underestimate the richness of the recordings but deny Johnson any political awareness or agency. In cautioning against this kind of project, I call for a hearing open to plural interpretations, and suggest political potential not only in coded messages, but in radical indeterminacy itself.

    2012-01-01

    This paper proves that an "old dog", namely -- the classical Johnson-Lindenstrauss transform, "performs new tricks" -- it gives a novel way of preserving differential privacy. We show that if we take two databases, $D$ and $D'$, such that (i) $D'-D$ is a rank-1 matrix of bounded norm and (ii) all singular values of $D$ and $D'$ are sufficiently large, then multiplying either $D$ or $D'$ with a vector of iid normal Gaussians yields two statistically close distributions in the sense of differential privacy. Furthermore, a small, deterministic and \\emph{public} alteration of the input is enough to assert that all singular values of $D$ are large. We apply the Johnson-Lindenstrauss transform to the task of approximating cut-queries: the number of edges crossing a $(S,\\bar S)$-cut in a graph. We show that the JL transform allows us to \\emph{publish a sanitized graph} that preserves edge differential privacy (where two graphs are neighbors if they differ on a single edge) while adding only $O(|S|/\\epsilon)$ random ...

  19. James Weldon Johnson and the Speech Lab Recordings

    Directory of Open Access Journals (Sweden)

    Chris Mustazza

    2016-03-01

    Full Text Available On December 24, 1935, James Weldon Johnson read thirteen of his poems at Columbia University, in a recording session engineered by Columbia Professor of Speech George W. Hibbitt and Barnard colleague Professor W. Cabell Greet, pioneers in the field that became sociolinguistics. Interested in American dialects, Greet and Hibbitt used early sound recording technologies to preserve dialect samples. In the same lab where they recorded T.S. Eliot, Gertrude Stein, and others, James Weldon Johnson read a selection of poems that included several from his seminal collection God’s Trombones and some dialect poems. Mustazza has digitized these and made them publicly available in the PennSound archive. In this essay, Mustazza contextualizes the collection, considering the recordings as sonic inscriptions alongside their textual manifestations. He argues that the collection must be heard within the frames of its production conditions—especially its recording in a speech lab—and that the sound recordings are essential elements in an hermeneutic analysis of the poems. He reasons that the poems’ original topics are reframed and refocused when historicized and contextualized within the frame of The Speech Lab Recordings.

    The concept of Virtual Monte Carlo (VMC) has been developed by the ALICE Software Project to allow different Monte Carlo simulation programs to run without changing the user code, such as the geometry definition, the detector response simulation or input and output formats. Recently, the VMC classes have been integrated into the ROOT framework, and the other relevant packages have been separated from the AliRoot framework and can be used individually by any other HEP project. The general concept of the VMC and its set of base classes provided in ROOT will be presented. Existing implementations for Geant3, Geant4 and FLUKA and simple examples of usage will be described.

    Carlo Caso (1940 - 2007) Our friend and colleague Carlo Caso passed away on July 7th, after several months of courageous fight against cancer. Carlo spent most of his scientific career at CERN, taking an active part in the experimental programme of the laboratory. His long and fruitful involvement in particle physics started in the sixties, in the Genoa group led by G. Tomasini. He then made several experiments using the CERN liquid hydrogen bubble chambers -first the 2000HBC and later BEBC- to study various facets of the production and decay of meson and baryon resonances. He later made his own group and joined the NA27 Collaboration to exploit the EHS Spectrometer with a rapid cycling bubble chamber as vertex detector. Amongst their many achievements, they were the first to measure, with excellent precision, the lifetime of the charmed D mesons. At the start of the LEP era, Carlo and his group moved to the DELPHI experiment, participating in the construction and running of the HPC electromagnetic c...

    Tat’yana N. Kovalyova

    2015-11-01

    Full Text Available Ivan Bunin created his “Travel Poems” — “The Bird’s Shadow” — based on the impressions of his wanderings, between 1903 and 1909, across the Middle East countries including Turkey, Judaea, Palestine, Syria, Egypt, Algeria, Tunisia and Greece. Modern researchers present the East of Bunin’s “Travel Poems” as a certain generalized image of a “culturological aspect”which comprises the historical and cultures features of diff erent countries of the Levant. Meanwhile, Bunin emphasized that he took his journeys to Judaea and Palestine as a pilgrimage to the Holy Land, not as mere leisure travels. The importance of the Bible East in the “Travel Poems” is also determined by the fact that the largest part of his routes and most of his essays (7 essays of 11 are related to the Holy Land. Th is article examines the artistic space-time of the Palestinian Essays by Bunin and reveals and characterizes the biblical chronotope and the role of the key topos of the Old Testament and the New Testament. However, the author emphasizes a special meaning of some biblical topos. These are the places associated with the key biblical events and with intentionality of author’s consciousness, which generate a broad range of the keynotes of the cycle of stories: the Valley of Josaphat as the place of the upcoming Last Judgement; the Dead Sea as the symbol of visitation of God for the people’s sins; the Judean Desert where Jesus was tempted by devil; Jerusalem, Bethlehem, Nazareth, Gennisaret as the cities of ancient Palestine related to the events of the Terrestrial Life of Jesus Christ. The hero’s perception of the holy places, domination of the biblical space-time in the “Travel Poems” devoted to the pilgrimage to the Holy Land, aspiration for being projected to the biblical times, unity of the hero’s chronotope with the biblical chronotope — all this indicates the extreme importance of the biblical events for the author

    Full Text Available Célèbre écrivain russe du début du XXe siècle, Ivan Šmelёv (1873-1950 doit, après les événements d’Octobre 1917, quitter la Russie avec sa femme. Le couple s’installe à Berlin en 1922 puis en France en 1923. Cette émigration forcée marque une nouvelle période dans la vie et dans l’œuvre de l’écrivain. Les biographies consacrées à Šmelёv s’accordent toutes sur un point : sa vie en exil fut extrêmement difficile et dès son arrivée, l’écrivain fut amer vis-à-vis de son pays d’accueil et de ses habitants. En effet, bien qu’il ait vécu un quart de siècle sur sa terre d’accueil, l’écrivain ne s’y intégra jamais vraiment, faisant le choix de rester en marge de la société française. Il reste à comprendre pourquoi Šmelёv n’a jamais pu s’y intégrer. Dans le présent article, je me propose de tenter de répondre à cette question en me basant sur les textes de l’écrivain. Pour ce faire, je retrace tout d’abord, étape par étape, les raisons qui l’ont poussé à s’installer en France. Ensuite, je me focalise sur l’évolution de ses ressentiments durant son exil. Enfin, dans la dernière partie, je mets en évidence quelques éléments de corrélation entre sa non-intégration dans la société d’accueil et son repli sur lui-même.

    Full Text Available Subject of this research is establishment of a spine deformity existence in students of the secondary school „Ivan-Goran Kovačić“ based in Herceg Novi, and the school role in their removal. The aim of the research is to provide actual knowledge and results about grow, growth and body posture conditions of students at the secondary school „Ivan-Goran Kovačić“in Herceg Novi. The sample is represented by 115 students, assigned in four classes. The selected sample is made of four classes, out of which is one from each grade, i.e. first, second, third and fourth grade. Those classes represent the student population in the whole school. Variables in this research, at the selected sample of students, are follows: spine deformities, lordosis, kyphosis and scoliosis. Analysis of the results obtained after the research has been completed shows that the functional stage of scoliotic deformity is presented at the majority students from the sample. The number of students with kyphosis and lordosis deformity of spine is considerably lower. Research results show that scoliotic, kyphotic and lordotic body postures are in the range of functional changes. Scoliosis deformities of spine were, as per the results, more presented in the female students than in the male students

    Full Text Available The purpose of this paper is to report a rare occurrence of Stevens-Johnson/Toxic epidermal necrolysis (SJS/TEN overlap syndrome after the use of aceclofenac. A 38 year old healthy adult male presented with rapidly evolving rash over face and upper body with ulceration of buccal mucosa and breathlessness after taking aceclofenac tablet. Naranjo score for this adverse drug event was six, thereby making it a probable adverse drug reaction. Despite aggressive fluid resuscitation and use of antihistamines and systemic steroids, patient′s health rapidly worsened and died within six hours of presentation. Aceclofenac induced SJS/TEN overlap is an extremely rare clinical association previously reported only once in medical literature. To the best of our knowledge, this is the first case report of such an association in the Indian population. We are presenting this case to highlight the serious adverse reactions possible from a routinely prescribed drug.

    2017-01-01

    Stevens-Johnson syndrome (SJS) is characterized by mucocutaneous tenderness and typical hemorrhagic erosions, erythema and epidermal detachment presenting as blisters and areas of denuded skin. SJS is often observed after drug use as well as after bacterial or viral infections. Several drugs are at high risk of inducing SJS, but there are no cases in the English literature regarding anabolic steroid use triggering SJS. In our paper, we describe a case in which use of anabolic androgenic steroids (AAS) was associated with SJS. The patient participated in competitive body-building and regularly took variable doses of AAS. Initial symptoms (headache, weakness, pharyngodynia, and fever) were ignored. After a week he presented to the Emergency Department with a burning sensation on the mouth, lips, and eyes. Painful, erythematous, maculopapular, and vesicular lesions appeared all over the body, including on the genitals. During hospitalization, he also developed a cardiac complication. The patient had not taken any drugs except AAS.

  12. Revisiting Johnson and Jackson boundary conditions for granular flows

    Li, Tingwen; Benyahia, Sofiane

    2012-07-01

    In this article, we revisit Johnson and Jackson boundary conditions for granular flows. The oblique collision between a particle and a flat wall is analyzed by adopting the classic rigid-body theory and a more realistic semianalytical model. Based on the kinetic granular theory, the input parameter for the partial-slip boundary conditions, specularity coefficient, which is not measurable in experiments, is then interpreted as a function of the particle-wall restitution coefficient, the frictional coefficient, and the normalized slip velocity at the wall. An analytical expression for the specularity coefficient is suggested for a flat, frictional surface with a low frictional coefficient. The procedure for determining the specularity coefficient for a more general problem is outlined, and a working approximation is provided.

    Full Text Available In the contemporary era, use of drugs is the dominant paradigm of health care. The most quotidian drug used for fever and pain is paracetamol. Although adverse reactions to paracetamol in India are rare, at times they can cause life-threatening situations. Stevens-Johnson syndrome (SJS is one such potentially lethal adverse drug reaction. The most reported cases of analgesic-induced SJS were due to oxicams or propionic acid derivatives. There are very few detailed reports of SJS due to the use of paracetamol. We report a case of SJS, which occurred due to the use of paracetamol. The clinical features of this condition and multidisciplinary management of the patient are described in brief.

    2017-01-01

    The NASA/Johnson Space Center has been developing robotic systems in support of space exploration for more than two decades. The goal of the Center's Robotic Systems Technology Branch is to design and build hardware and software to assist astronauts in performing their mission. These systems include: rovers, humanoid robots, inspection devices and wearable robotics. Inspection systems provide external views of space vehicles to search for surface damage and also maneuver inside restricted areas to verify proper connections. New concepts in human and robotic rovers offer solutions for navigating difficult terrain expected in future planetary missions. An important objective for humanoid robots is to relieve the crew of "dull, dirty or dangerous" tasks allowing them more time to perform their important science and exploration missions. Wearable robotics one of the Center's newest development areas can provide crew with low mass exercise capability and also augment an astronaut's strength while wearing a space suit. This presentation will describe the robotic technology and prototypes developed at the Johnson Space Center that are the basis for future flight systems. An overview of inspection robots will show their operation on the ground and in-orbit. Rovers with independent wheel modules, crab steering, and active suspension are able to climb over large obstacles, and nimbly maneuver around others. Humanoid robots, including the First Humanoid Robot in Space: Robonaut 2, demonstrate capabilities that will lead to robotic caretakers for human habitats in space, and on Mars. The Center's Wearable Robotics Lab supports work in assistive and sensing devices, including exoskeletons, force measuring shoes, and grasp assist gloves.

    Full Text Available El método Monte Carlo se aplica a varios casos de valoración de opciones financieras. El método genera una buena aproximación al comparar su precisión con la de otros métodos numéricos. La estimación que produce la versión Cruda de Monte Carlo puede ser aún más exacta si se recurre a metodologías de reducción de la varianza entre las cuales se sugieren la variable antitética y de la variable de control. Sin embargo, dichas metodologías requieren un esfuerzo computacional mayor por lo cual las mismas deben ser evaluadas en términos no sólo de su precisión sino también de su eficiencia.

    The Monte Carlo method is widely used to numerically predict systems behaviour. However, its powerful incremental design assumes a strong premise which has severely limited application so far: the estimation process must combine linearly over dimensions. Here we show that this premise can be alleviated by projecting nonlinearities on a polynomial basis and increasing the configuration-space dimension. Considering phytoplankton growth in light-limited environments, radiative transfer in planetary atmospheres, electromagnetic scattering by particles and concentrated-solar-power-plant productions, we prove the real world usability of this advance on four test-cases that were so far regarded as impracticable by Monte Carlo approaches. We also illustrate an outstanding feature of our method when applied to sharp problems with interacting particles: handling rare events is now straightforward. Overall, our extension preserves the features that made the method popular: addressing nonlinearities does not compromise o...

  2. Who Writes Carlos Bulosan?

    2001-12-01

    Full Text Available The importance of Carlos Bulosan in Filipino and Filipino-American radical history and literature is indisputable. His eminence spans the pacific, and he is known, diversely, as a radical poet, fictionist, novelist, and labor organizer. Author of the canonical America Iis the Hearts, Bulosan is celebrated for chronicling the conditions in America in his time, such as racism and unemployment. In the history of criticism on Bulosan's life and work, however, there is an undeclared general consensus that views Bulosan and his work as coherent permanent texts of radicalism and anti-imperialism. Central to the existence of such a tradition of critical reception are the generations of critics who, in more ways than one, control the discourse on and of Carlos Bulosan. This essay inquires into the sphere of the critical reception that orders, for our time and for the time ahead, the reading and interpretation of Bulosan. What eye and seeing, the essay asks, determine the perception of Bulosan as the angel of radicalism? What is obscured in constructing Bulosan as an immutable figure of the political? What light does the reader conceive when the personal is brought into the open and situated against the political? the essay explores the answers to these questions in Bulosan's loving letters to various friends, strangers, and white American women. The presence of these interrogations, the essay believes, will secure ultimately the continuing importance of Carlos Bulosan to radical literature and history.

    Rasmussen, Teresa J.; Stone, Mandy S.; Poulton, Barry C.; Graham, Jennifer L.

    2012-01-01

    Stream quality in Johnson County, northeastern Kansas, was assessed on the basis of land use, hydrology, stream-water and streambed-sediment chemistry, riparian and in-stream habitat, and periphyton and macroinvertebrate community data collected from 22 sites during 2002 through 2010. Stream conditions at the end of the study period are evaluated and compared to previous years, stream biological communities and physical and chemical conditions are characterized, streams are described relative to Kansas Department of Health and Environment impairment categories and water-quality standards, and environmental factors that most strongly correlate with biological stream quality are evaluated. The information is useful for improving water-quality management programs, documenting changing conditions with time, and evaluating compliance with water-quality standards, total maximum daily loads (TMDLs), National Pollutant Discharge Elimination System (NPDES) permit conditions, and other established guidelines and goals. Constituent concentrations in water during base flow varied across the study area and 2010 conditions were not markedly different from those measured in 2003, 2004, and 2007. Generally the highest specific conductance and concentrations of dissolved solids and major ions in water occurred at urban sites except the upstream Cedar Creek site, which is rural and has a large area of commercial and industrial land less than 1 mile upstream on both sides of the creek. The highest base-flow nutrient concentrations in water occurred downstream from wastewater treatment facilities. Water chemistry data represent base-flow conditions only, and do not show the variability in concentrations that occurs during stormwater runoff. Constituent concentrations in streambed sediment also varied across the study area and some notable changes occurred from previously collected data. High organic carbon and nutrient concentrations at the rural Big Bull Creek site in 2003 decreased

  9. Patronage power: Rural electrification, river development, and Lyndon Johnson (1937--1939)

    Science.gov (United States)

    Dusek, Paul-Michael Mays

    Few historians document Lyndon Johnson's efforts to construct a state-wide political machine at the local level early in his congressional career. The literature glorifies Johnson for hydroelectric river development and rural electrification. This thesis acknowledges the transformative nature of rural electrification in Central Texas through the efforts of Johnson but, more importantly, reveals how extensively Johnson sought to capitalize on the tail-end of the New Deal to utilize government-funded relief projects to establish a state-wide political machine. An analysis of the correspondence between Johnson, his local political operators, members of his state-wide network, and rural constituents reveals another layer to the complexity of Johnson and further exposes his ambitious, calculating nature. Johnson used rural electrification to first create a community of supporters in his congressional district then used rural electrification and multipurpose river development programs to cultivate political contacts across the state of Texas. This thesis explores the first time that Lyndon Johnson used patronage to develop a political community as a publicly elected official. Johnson pushed for constant expansion of operations to ensure a steady supply of new jobs while displaying a cavalier attitude about specific regulations regarding the allocation of funds. His machine manipulated and massaged congressional appropriations restrictions and utilized multiple congressional revenue streams to stretch finances further and lower overhead costs to increase the scope of operations thus further improving the lives of his constituents. Johnson also used this movement to efficiently and effectively construct a foundation for his political machine. This thesis also clarifies an early moment in Johnson's beliefs about civil rights. Instead of standing on principle, Johnson relied on extortion and threats to fight racism at this early juncture in his political career because of

    The Nez Perce Tribe, through funding provided by the Bonneville Power Administration, has implemented a small scale chinook salmon supplementation program on Johnson Creek, a tributary in the South Fork of the Salmon River, Idaho. The Johnson Creek Artificial Propagation Enhancement project was established to enhance the number of threatened Snake River summer chinook salmon (Oncorhynchus tshawytscha) returning to Johnson Creek through artificial propagation. Adult chinook salmon collection and spawning began in 1998. A total of 114 fish were collected from Johnson Creek and 54 fish (20 males and 34 females) were retained for Broodstock. All broodstock were transported to Lower Snake River Compensation Plan's South Fork Salmon River adult holding and spawning facility, operated by the Idaho Department of Fish and Game. The remaining 60 fish were released to spawn naturally. An estimated 155,870 eggs from Johnson Creek chinook spawned at the South Fork Salmon River facility were transported to the McCall Fish Hatchery for rearing. Average fecundity for Johnson Creek females was 4,871. Approximately 20,500 eggs from females with high levels of Bacterial Kidney Disease were culled. This, combined with green-egg to eyed-egg survival of 62%, resulted in about 84,000 eyed eggs produced in 1998. Resulting juveniles were reared indoors at the McCall Fish Hatchery in 1999. All of these fish were marked with Coded Wire Tags and Visual Implant Elastomer tags and 8,043 were also PIT tagged. A total of 78,950 smolts were transported from the McCall Fish Hatchery and released directly into Johnson Creek on March 27, 28, 29, and 30, 2000.

    Full Text Available A letter addressed by the Bishop Vasile of Roman to Gerontius, the Metropolitan of Moscow, reflects an early dialogue between the Romanian and the Russian ecclesiastic hierarchy. It is one of the oldest evidence on the relations of the Romanian Church (or "Metropolitan of the Lower Country of Moldova" with the Russian Church (or the Metropolitan of Moscow. The letter appears in the context of misunderstanding between the grand prince of Muscovy, Ivan III, and Gerontius, the Metropolitan of Moscow. During the consecration of the cathedral "Uspenia" in Moscow, the Metropolitan has surrounded the church with all his ministers’ council, against the sun. The prince of Moscow was dissatisfied by this ordinance and started the conflict with the highest priest.

    The Regenerative Life Support Systems (RLSS) Test Bed at NASA's Johnson Space Center is an atmospherically closed, controlled environment facility for human testing of regenerative life support systems using higher plants in conjunction with physicochemical life support systems. The facility supports NASA's Advanced Life Support (ALS) Program. The facility is comprised of two large scale plant growth chambers, each with approximately 11 m^2 growing area. The root zone in each chamber is configurable for hydroponic or solid media plant culture systems. One of the two chambers, the Variable Pressure Growth Chamber (VPGC), is capable of operating at lower atmospheric pressures to evaluate a range of environments that may be used in a planetary surface habitat; the other chamber, the Ambient Pressure Growth Chamber (APGC) operates at ambient atmospheric pressure. The air lock of the VPGC is currently being outfitted for short duration (1 to 15 day) human habitation at ambient pressures. Testing with and without human subjects will focus on 1) integration of biological and physicochemical air and water revitalization systems; 2) effect of atmospheric pressure on system performance; 3) planetary resource utilization for ALS systems, in which solid substrates (simulated planetary soils or manufactured soils) are used in selected crop growth studies; 4) environmental microbiology and toxicology; 5) monitoring and control strategies; and 6) plant growth systems design. Included are descriptions of the overall design of the test facility, including discussions of the atmospheric conditioning, thermal control, lighting, and nutrient delivery systems.

    The Small Business Innovation Research (SBIR) Program increases opportunities for small businesses to participate in research and development (R&D), increases employment, and improves U.S. competitiveness. Specifically the program stimulates U.S. technological innovation by using small businesses to meet federal R&D needs, increasing private-sector commercialization of innovations derived from federal R&D, and fostering and encouraging the participation of socially disadvantaged businesses. In 2000, the Small Business Technology Transfer (STTR) Program extended and strengthened the SBIR Program, increasing its emphasis on pursuing commercial applications by awarding contracts to small business concerns for cooperative R&D with a nonprofit research institution. Modeled after the SBIR Program, STTR is nevertheless a separately funded activity. Technologies that have resulted from the Johnson Space Center SBIR STTR Program include: a device for regenerating iodinated resin beds; laser-assisted in-situ keratomileusis or LASIK; a miniature physiological monitoring device capable of collecting and analyzing a multitude of real-time signals to transmit medical data from remote locations to medical centers for diagnosis and intervention; a new thermal management system for fibers and fabrics giving rise to new line of garments and thermal-enhancing environments; and a highly electropositive material that attracts and retains electronegative particles in water.

  15. Stevens-Johnson syndrome and toxic epidermal necrolysis: a review

    Directory of Open Access Journals (Sweden)

    Anthony Wong

    Full Text Available SUMMARY Stevens-Johnson syndrome (SJS and toxic epidermal necrolysis (TEN are uncommon, acute and potentially life-threatening adverse cutaneous drug reactions. These pathologies are considered a hypersensitivity reaction and can be triggered by drugs, infections and malignancies. The drugs most often involved are allopurinol, some antibiotics, including sulfonamides, anticonvulsants such as carbamazepine, and some non-steroid anti-inflammatory drugs (NSAIDs. Necrosis of keratinocytes is manifested clinically by epidermal detachment, leading to scalded skin appearance. The rash begins on the trunk with subsequent generalization, usually sparing the palmoplantar areas. Macular lesions become purplish, and epidermal detachment occurs, resulting in flaccid blisters that converge and break, resulting in extensive sloughing of necrotic skin. Nikolsky's sign is positive in perilesional skin. SJS and TEN are considered to be two ends of the spectrum of one disease, differing only by their extent of skin detachment. Management of patients with SJS or TEN requires three measures: removal of the offending drug, particularly drugs known to be high-risk; supportive measures and active interventions. Early diagnosis of the disease, recognition of the causal agent and the immediate withdrawal of the drug are the most important actions, as the course of the disease is often rapid and fatal.

    2005-01-01

    Nanomaterials activities at NASA-Johnson Space Center focus on single wall carbon nanotube production, characterization and their applications for aerospace. Nanotubes are produced by arc and laser methods and the growth process is monitored by in-situ diagnostics using time resolved passive emission and laser induced fluorescence of the active species. Parametric study of both these processes are conducted to monitor the effect of production parameters including temperature, buffer gas, flow rate, pressure, laser fluence and arc current. Characterization of the nanotube material is performed using the NASA-JSC protocol developed by combining analytical techniques of SEM, TEM, UV-VIS-NIR absorption, Raman, and TGA. Efforts at JSC over the past five years in composites have centered on structural polymernanotube systems. Recent activities broadened this focus to multifunctional materials, supercapacitors, fuel cells, regenerable CO2 absorbers, electromagnetic shielding, radiation dosimetry and thermal management systems of interest for human space flight. Preliminary tests indicate improvement of performance in most of these applications because of the large surface area as well as high conductivity exhibited by SWCNTs.

    Full Text Available Toxic epidermal necrolysis (TEN and Stevens Johnson Syndrome (SJS are severe adverse cutaneous drug reactions that predominantly involve the skin and mucous membranes. They are characterized by mucocutaneous tenderness and typically hemorrhagic erosions, erythema and more or less severe epidermal detachment presenting as blisters and areas of denuded skin. Drugs are assumed or identified as the main cause of SJS/TEN in most cases, but Mycoplasma pneumoniae and Herpes simplex virus infections are well documented causes alongside rare cases in which the etiology remains unknown. Several drugs are at "high" risk of inducing TEN/SJS including: Allopurinol, Trimethoprim-sulfamethoxazole and other sulfonamide-antibiotics, aminopenicillins, cephalosporins, quinolones, carbamazepine, phenytoin, phenobarbital and NSAID's of the oxicam-type. Differential diagnosis includes linear IgA dermatosis and paraneoplastic pemphigus, pemphigus vulgaris and bullous pemphigoid, acute generalized exanthematous pustulosis (AGEP, disseminated fixed bullous drug eruption and staphyloccocal scalded skin syndrome (SSSS. Due to the high risk of mortality, management of patients with SJS/TEN requires rapid diagnosis, identification and interruption of the culprit drug, specialized supportive care ideally in an intensive care unit, and consideration of immunomodulating agents such as high-dose intravenous immunoglobulin therapy.

    Research activities on carbon nanotubes at NASA-Johnson Space Center include production, purification, characterization and their applications for human space flight. In-situ diagnostics during nanotube production by laser oven process include collection of spatial and temporal data of passive emission and laser induced fluorescence from C2, C3 and Nickel atoms in the plume. Details of the results from the "parametric study" of the pulsed laser ablation process indicate the effect of production parameters including temperature, buffer gas, flow rate, pressure, and laser fluence. Improvement of the purity by a variety of steps in the purification process is monitored by characterization techniques including SEM, TEM, Raman, UV-VIS-NIR and TGA. A recently established NASA-JSC protocol for SWCNT characterization is undergoing revision with feedback from nanotube community. Efforts at JSC over the past five years in composites have centered on structural polymednanotube systems. Recent activities broadened this focus to multifunctional materials, supercapacitors, fuel cells, regenerable CO2 absorbers, electromagnetic shielding, radiation dosimetry and thermal management systems of interest for human space flight.

    LMC is a Markov Chain Monte Carlo engine in Python that implements adaptive Metropolis-Hastings and slice sampling, as well as the affine-invariant method of Goodman & Weare, in a flexible framework. It can be used for simple problems, but the main use case is problems where expensive likelihood evaluations are provided by less flexible third-party software, which benefit from parallelization across many nodes at the sampling level. The parallel/adaptive methods use communication through MPI, or alternatively by writing/reading files, and mostly follow the approaches pioneered by CosmoMC (ascl:1106.025).

    The Nez Perce Tribe, through funding provided by the Bonneville Power Administration, has implemented a small scale chinook salmon supplementation program on Johnson Creek, a tributary in the South Fork of the Salmon River, Idaho. The Johnson Creek Artificial Propagation Enhancement project was established to enhance the number of threatened Snake River spring/summer chinook salmon (Oncorhynchus tshawytscha) returning to Johnson Creek to spawn through artificial propagation. This was the sixth season of adult chinook broodstock collection in Johnson Creek following collections in 1998, 2000, 2001, 2002, and 2003. Weir installation was completed on June 21, 2004 with the first chinook captured on June 22, 2004 and the last fish captured on September 6, 2004. The weir was removed on September 18, 2004. A total of 338 adult chinook, including jacks, were captured during the season. Of these, 211 were of natural origin, 111 were hatchery origin Johnson Creek supplementation fish, and 16 were adipose fin clipped fish from other hatchery operations and therefore strays into Johnson Creek. Over the course of the run, 57 natural origin Johnson Creek adult chinook were retained for broodstock, transported to the South Fork Salmon River adult holding and spawning facility and held until spawned. The remaining natural origin Johnson Creek fish along with all the Johnson Creek supplementation fish were released upstream of the weir to spawn naturally. Twenty-seven Johnson Creek females were artificially spawned with 25 Johnson Creek males. Four females were diagnosed with high bacterial kidney disease levels resulting in their eggs being culled. The 27 females produced 116,598 green eggs, 16,531 green eggs were culled, with an average eye-up rate of 90.6% resulting in 90,647 eyed eggs. Juvenile fish were reared indoors at the McCall Fish Hatchery until November 2005 and then transferred to the outdoor rearing facilities during the Visual Implant Elastomer tagging operation

    The internal and external noise is the most considering obstacle in development of Johnson Noise Thermometry system. This paper addresses an external noise elimination issue of the Johnson Noise Thermometry system which is underway of development in collaboration between KAERI and ORNL. Although internal random noise is canceled by Cross Power Spectral Density function, a continuous wave penetrating into the electronic circuit is eliminated by the difference of peaks between Johnson signal and external noise. The elimination logic using standard deviation of CPSD and energy leakage problem in discrete CPSD function are discussed in this paper.

    The Johnson Space Center (JSC), located in the southeast metropolitan region of Houston, TX is the prime NASA center for human spaceflight operations and astronaut training, but it also houses the unique collection of returned extraterrestrial samples, including lunar samples from the Apollo missions. The Center's location adjacent to Clear Lake and the Clear Creek watershed, an estuary of Galveston Bay, puts it at direct annual risk from hurricanes, but also from a number of other climate-related hazards including drought, floods, sea level rise, heat waves, and high wind events all assigned Threat Levels of 2 or 3 in the most recent NASA Center Disaster/Risk Matrix produced by the Climate Adaptation Science Investigator Working Group. Based on prior CASI workshops at other NASA centers, it is recognized that JSC is highly vulnerable to climate-change related hazards and has a need for adaptation strategies. We will present an overview of prior CASI-related work at JSC, including publication of a climate change and adaptation informational data brochure, and a Resilience and Adaptation to Climate Risks Workshop that was held at JSC in early March 2012. Major outcomes of that workshop that form a basis for work going forward are 1) a realization that JSC is embedded in a regional environmental and social context, and that potential climate change effects and adaptation strategies will not, and should not, be constrained by the Center fence line; 2) a desire to coordinate data collection and adaptation planning activities with interested stakeholders to form a regional climate change adaptation center that could facilitate interaction with CASI; 3) recognition that there is a wide array of basic data (remotely sensed, in situ, GIS/mapping, and historical) available through JSC and other stakeholders, but this data is not yet centrally accessible for planning purposes.

    Irreversible displacements in dams are associated with alkali-aggregate reaction, creep, and other damaging effects that compromise the safety of dams. An identification of the nature of irreversible displacements is needed to predict the future behaviour of dams as well as to select appropriate remedial measures. This paper provided details of a principal component analysis (PCA) used to investigate swelling and small irreversible displacements observed at the Daniel-Johnson dam in Quebec. PCA is a multivariate statistical method that performs the analysis of correlations or covariances between several random variables simultaneously. Three datasets were used: (1) reservoir water level; (2) air temperature; and (3) pendulum displacements. Standard linear regression analyses (HST) were performed for each variable in order to eliminate outliers and replace missing values. The multivariate dataset was then used to perform PCA on the entire dataset as well as on subsets from the original data. Displacement data from pendulums were used in the multivariate statistical analysis in which each component was treated as a separate variable. The comparison of irreversible displacements of the dam from HST analysis and principal component analysis (PCA) indicated that results were consistent with the data. The PCA analysis identified dominant patterns of behaviour and detected 2 distinct components of irreversible deformations arising from creep and swelling of concrete. Results of the study showed that the PCA analysis led to a better understanding of the overall behaviour of the dam and of individual arches and buttresses. It was concluded that the PCA analysis method will help to improve dam safety in addition to more accurately predicting the future behaviour of dams. 6 refs., 2 tabs., 9 figs.

    Reports an error in "Parental racial socialization profiles: Association with demographic factors, racial discrimination, childhood socialization, and racial identity" by Rhonda L. White-Johnson, Kahlil R. Ford and Robert M. Sellers (Cultural Diversity and Ethnic Minority Psychology, 2010[Apr], Vol 16[2], 237-247). In the article, there was an error in the Measures subsection. The following citation should have been included in the third paragraph " Mothers' childhood racial socialization experiences. Prior racial socialization messages were assessed using four items adapted from the Comprehensive Race Socialization Inventory (Lesane- Brown, Brown, Caldwell, & Sellers, 2005)." Additionally, the included reference should have been included in the Reference section. (The following abstract of the original article appeared in record 2010-07475-016.) The authors examined patterns of racial socialization practices in a sample of 212 African American mothers. They investigated the relation between parent profiles of racial socialization messages with child and parent demographic factors and race-related experiences, as well as parent racial identity attitudes. Using latent class analyses, the authors identified 3 patterns of parent-reported racial socialization experiences: multifaceted, low race salience, and unengaged. In general, findings indicate that mothers in the multifaceted profile were more educated, experienced more racial discrimination, and talked about race during their childhood more than mothers in the unengaged profile. The multifaceted profile also differed from the low race salience and unengaged profiles on several racial identity dimensions. Although the patterned approach used in this study lends itself to a more complex study of racial socialization in future research, it also highlights the associations between parent's race-relevant experiences and the messages they communicate to their children about race.

    2015-01-01

    HIV/AIDS has claimed millions of lives in the global workforce and continues to remain a threat to many businesses. An estimated 36.5 million of working people are living with HIV; the global workforce has lost 28 million people from AIDS since the beginning of the epidemic. In the absence of access to treatment, this number could grow to 74 million by 2015. The epidemic continues to affect the working population through absenteeism, sickness and death. Corporate Social Responsibility (CSR) is an obligation that corporates have toward their employees, community and society. A review and documentation of one such CSR by Johnson & Johnson (a multinational company) for HIV/AIDS in Africa is presented here. Johnson & Johnson Company is involved in numerous projects around the world to combat the HIV/AIDS epidemic. The company is working to fight the spread of the disease and improve the quality of life for those living with the illness through various donations of its products and sponsorship of local programs. This case study also highlights different categories of CSR activities such as Cause Promotion, Cause related Marketing, Corporate Philanthropy, Corporate Social Marketing, Corporate Volunteering and Socially responsible business practices, which are discussed with specific examples from different countries in Africa. CSR of any business encompasses the economic, legal, ethical & discretionary expectation placed on the organization by society at a given point of time. CSR is therefore the obligation that corporations have toward their stakeholders and society in general which horizons beyond what is prescribed by law or union contracts. Johnson & Johnson has a proved history of being committed to caring for people and a good example of a company with a long history of citizenship and sustainability.

  16. Towards a practical Johnson noise thermometer for long-term measurements in harsh environments

    Energy Technology Data Exchange (ETDEWEB)

    The impact of mechanical and chemical changes in conventional sensors such as thermocouples and resistance thermometers can be avoided by instead using temperature sensors based on fundamental thermometry. A prime example of this is Johnson noise thermometry, which is based on measurement of the fluctuations in the voltage of a resistor arising from thermal motion of charge carriers - i.e. the 'Johnson noise'. A Johnson noise thermometer never needs calibration and is insensitive to the condition of the sensor material. It is therefore ideally suited to long-term temperature measurements in harsh environments, such as nuclear reactor coolant circuits, in-pile measurements, nuclear waste management and storage, and severe accident monitoring. There have been a number of previous attempts to develop a Johnson noise thermometer for the nuclear industry, but none have reached commercial exploitation because of technical problems in practical implementation. The main challenge is to extract the tiny Johnson noise signal from ambient electrical noise influences, both from the internal amplification electronics, and from external electrical noise sources. Recent advances in electronics technology and digital signal processing techniques have opened up new possibilities for developing a viable, practical Johnson noise thermometer. We describe a project funded by the UK Technology Strategy Board (now Innovate UK) 'Developing the nuclear supply chain' call, currently underway, to develop a practical Johnson noise thermometer that makes use of innovative electronics for ultralow noise amplification and signal processing. The new electronics technology has the potential to help overcome the problems encountered with previous attempts at constructing a practical Johnson noise thermometer. An outline of the new developments is presented, together with an overview of the current status of the project. (authors)

  17. The Development of a Practical, Drift-Free, Johnson-Noise Thermometer for Industrial Applications

    Bramley, Paul; Cruickshank, David; Pearce, Jonathan

    2017-02-01

    Johnson noise thermometers measure a phenomenon that is directly linked to thermodynamic temperature by a fundamental physical law. The measurement of Johnson noise therefore offers the prospect of realizing a drift-free thermometer. Despite previous attempts to produce a practical Johnson noise thermometer for industrial applications, the technique is currently used only in niche research applications to explore discrepancies between practical temperature scales and thermodynamic temperature, or to determine Boltzmann's constant. This has largely been due to the historical use of switched correlators to measure Johnson noise, which limits the sense resistance and measurement bandwidth that can be employed. This constraint limits the Johnson noise signal to levels near the limits of measurement. A new technique that eliminates switching and thereby allows the use of much higher sense resistances and bandwidths to increase the Johnson noise signal is presented. The signal power achieved is significantly higher than for systems using a switched correlator. Results so far indicate that measurement performance is compatible with the requirements of industrial applications. Specifically, uncertainties of <0.3°C (95 % confidence) were demonstrated for measurements near ambient temperature with a measurement time of only 7 s.

    The Japan Aerospace Exploration Agency (JAXA) Hayabusa spacecraft made contact with the asteroid 25143 Itokawa and collected regolith dust from Muses Sea region of smooth terrain [1]. The spacecraft returned to Earth with more than 10,000 grains ranging in size from just over 300 µm to less than 10 µm [2, 3]. These grains represent the only collection of material returned from an asteroid by a spacecraft. As part of the joint agreement between JAXA and NASA for the mission, 10% of the Hayabusa grains are being transferred to NASA for parallel curation and allocation. In order to properly receive process and curate these samples, a new curation facility was established at Johnson Space Center (JSC). Since the Hayabusa samples within the JAXA curation facility have been stored free from exposure to terrestrial atmosphere and contamination [4], one of the goals of the new NASA curation facility was to continue this treatment. An existing lab space at JSC was transformed into a 120 sq.ft. ISO class 4 (equivalent to the original class 10 standard) clean room. Hayabusa samples are stored, observed, processed, and packaged for allocation inside a stainless steel glove box under dry N2. Construction of the clean laboratory was completed in 2012. Currently, 25 Itokawa particles are lodged in NASA's Hayabusa Lab. Special care has been taken during lab construction to remove or contain materials that may contribute contaminant particles in the same size range as the Hayabusa grains. Several witness plates of various materials are installed around the clean lab and within the glove box to permit characterization of local contaminants at regular intervals by SEM and mass spectrometry, and particle counts of the lab environment are frequently acquired. Of particular interest is anodized aluminum, which contains copious sub-mm grains of a multitude of different materials embedded in its upper surface. Unfortunately the use of anodized aluminum was necessary in the construction

    In addition to the current NASA manned programs, the maturation of Space Station and the introduction of the Space Exploration programs are anticipated to add substantially to the number and variety of data and documentation at NASA Johnson Space Center (JSC). This growth in the next decade has been estimated at five to ten fold compared to the current numbers. There will be an increased requirement for the tracking and currency of space program data and documents with National pressures to realize economic benefits from the research and technological developments of space programs. From a global perspective the demand for NASA's technical data and documentation is anticipated to increase at local, national, and international levels. The primary users will be government, industry, and academia. In our present national strategy, NASA's research and technology will assume a great role in the revitalization of the economy and gaining international competitiveness. Thus, greater demand will be placed on NASA's data and documentation resources. In this paper the strategies and procedures developed by DDMS, Inc., to accommodate the present and future information utilization needs are presented. The DDMS, Inc., strategies and procedures rely on understanding user requirements, library management issues, and technological applications for acquiring, searching, storing, and retrieving specific information accurately and quickly. The proposed approach responds to changing customer requirements and product deliveries. The unique features of the proposed strategy include: (1) To establish customer driven data and documentation management through an innovative and unique methods to identify needs and requirements. (2) To implement a structured process which responds to user needs, aimed at minimizing costs and maximizing services, resulting in increased productivity. (3) To provide a process of standardization of services and procedures. This standardization is the central

  20. Toxic epidermal necrolysis and Stevens-Johnson syndrome

    2010-12-01

    Full Text Available Abstract Toxic epidermal necrolysis (TEN and Stevens Johnson Syndrome (SJS are severe adverse cutaneous drug reactions that predominantly involve the skin and mucous membranes. Both are rare, with TEN and SJS affecting approximately 1or 2/1,000,000 annually, and are considered medical emergencies as they are potentially fatal. They are characterized by mucocutaneous tenderness and typically hemorrhagic erosions, erythema and more or less severe epidermal detachment presenting as blisters and areas of denuded skin. Currently, TEN and SJS are considered to be two ends of a spectrum of severe epidermolytic adverse cutaneous drug reactions, differing only by their extent of skin detachment. Drugs are assumed or identified as the main cause of SJS/TEN in most cases, but Mycoplasma pneumoniae and Herpes simplex virus infections are well documented causes alongside rare cases in which the aetiology remains unknown. Several drugs are at "high" risk of inducing TEN/SJS including: Allopurinol, Trimethoprim-sulfamethoxazole and other sulfonamide-antibiotics, aminopenicillins, cephalosporins, quinolones, carbamazepine, phenytoin, phenobarbital and NSAID's of the oxicam-type. Genetic susceptibility to SJS and TEN is likely as exemplified by the strong association observed in Han Chinese between a genetic marker, the human leukocyte antigen HLA-B*1502, and SJS induced by carbamazepine. Diagnosis relies mainly on clinical signs together with the histological analysis of a skin biopsy showing typical full-thickness epidermal necrolysis due to extensive keratinocyte apoptosis. Differential diagnosis includes linear IgA dermatosis and paraneoplastic pemphigus, pemphigus vulgaris and bullous pemphigoid, acute generalized exanthematous pustulosis (AGEP, disseminated fixed bullous drug eruption and staphyloccocal scalded skin syndrome (SSSS. Due to the high risk of mortality, management of patients with SJS/TEN requires rapid diagnosis, evaluation of the prognosis

    In September 2004, rain from the remnants of Hurricanes Frances and Ivan triggered at least 155 landslides in the Blue Ridge Mountains of North Carolina. At least 33 debris flows occurred in Macon County, causing 5 deaths, destroying 16 homes, and damaging infrastructure. We mapped debris flows and debris deposits using a light-detecting and ranging digital elevation model, remote imagery and field studies integrated in a geographic information system. Evidence of past debris flows was found at all recent debris flow sites. Orographic rainfall enhancement along topographic escarpments influenced debris flow frequency at higher elevations. A possible trigger for the Wayah and fatal Peeks Creek debris flows was a spiral rain band within Ivan that moved across the area with short duration rainfall rates of 150-230 mm/h. Intersecting bedrock structures in polydeformed metamorphic rock influence the formation of catchments within structural-geomorphic domains where debris flows originate. ?? 2007 Springer-Verlag.

    Ivan I. Schmalhausen was one of the central figures in the Russian development of the "Modern Synthesis" in evolutionary biology. He is widely cited internationally even today. Schmalhausen developed the main principles of his theory facing the danger of death in the totalitarian Soviet Union. His great services to evolutionary and theoretical biology are indisputable. However, the received view of Schmalhausen's contributions to evolutionary biology makes an unbiased reading of his texts difficult. Here we show that taking all of his works into consideration (including those only available in Russian) paints a much more dynamic and exciting picture of what he tried to achieve. Schmalhausen pioneered the integration of a developmental perspective into evolutionary thinking. A main tool for achieving this was his approach to living objects as complex multi-level self-regulating systems. Schmalhausen put enormous effort into bringing this idea into fruition during the final stages of his career by combining evolutionary theory with cybernetics. His results and ideas remain thought-provoking, and his texts are of more than just historical interest.

    Villarini, Gabriele; Smith, James A.; Baeck, Mary Lynn; Marchok, Timothy; Vecchi, Gabriel A.

    2011-12-01

    Rainfall and flooding associated with landfalling tropical cyclones are examined through empirical analyses of three hurricanes (Frances, Ivan, and Jeanne) that affected large portions of the eastern U.S. during September 2004. Three rainfall products are considered for the analyses: NLDAS, Stage IV, and TMPA. Each of these products has strengths and weaknesses related to their spatio-temporal resolution and accuracy in estimating rainfall. Based on our analyses, we recommend using the Stage IV product when studying rainfall distribution in landfalling tropical cyclones due to its fine spatial and temporal resolutions (about 4-km and hourly) and accuracy, and the capability of estimating rainfall up to 150 km from the coast. Lagrangian analyses of rainfall distribution relative to the track of the storm are developed to represent evolution of the temporal and spatial structure of rainfall. Analyses highlight the profound changes in rainfall distribution near landfall, the changing contributions to the rainfall field from eyewall convection, inner rain bands and outer rain bands, and the key role of orographic amplification of rainfall. We also present new methods for examining spatial extreme of flooding from tropical cyclones and illustrate the links between evolving rainfall structure and spatial extent of flooding.

    The Johnson River Basin, located in Lake Clark National Park and Preserve, drains an area of 96 square miles. A private inholding in the upper part of the basin contains a gold deposit that may be developed in the future. To establish a natural baseline to compare potential effects on water quality if development were to occur, the upper part of the Johnson River Basin was studied from 1999 to 2001 as part of a cooperative study with the National Park Service. Two basic rock types occur within the drainage basin of the study: the Jurassic Talkeetna Formation of interbedded volcanic and volcaniclastic rocks, and the slightly younger plutonic rocks of the Aleutian-Alaska Ranges batholith. The Johnson River gold prospect reflects widespread, secondary mineralization and alteration of the Talkeetna Formation. Metals found at the prospect proper are: arsenic, cadmium, copper, gold, iron, lead, mercury, molybdenum, selenium, silver, and zinc. The Johnson River prospect is located in the East Fork Ore Creek Basin, a 0.5 square mile watershed that is a tributary to the Johnson River. Water quality data from this stream reflect the mineralization of the basin and the highest concentrations of several trace elements and major ions of the water column were found in this stream. Presently, pH in this stream is normal, indicating that there is sufficient buffering capacity. At the Johnson River streamgage, which drains approximately 25 mi2 including the East Fork Ore Creek, concentrations of these constituents are significantly lower, reflecting the runoff from Johnson Glacier and Double Glacier, which account for approximately 75 percent of the total discharge. Streambed concentrations of cadmium, lead, and zinc from East Fork Ore Creek and its receiving stream, Ore Creek, typically exceed concentrations where sediment dwelling organisms would be affected. Similar to the water column chemistry, concentrations of these elements are lower at the Johnson River streamgage

    Full Text Available Stevens-Johnson syndrome (SJS is an immune-complex mediated hypersensitivity reaction and has been linked as an adverse side effect to many drugs. This case is about a 25 year old woman who had lamotrigine-induced Stevens-Johnson syndrome which is known to occur but is rare. Lamotrigine, an anticonvulsive medication and also a commonly used mood stabilizer was prescribed to the patient to treat symptoms of anxiety and depression. The patient developed Stevens-Johnson syndrome 5 weeks after start of therapy. This case is discussed for its relevance to the use of lamotrigine which is currently prescribed very commonly in psychiatric practices. [Int J Basic Clin Pharmacol 2016; 5(6.000: 2694-2696

    Full Text Available Stevens Johnson syndrome is a life threatening IgE mediated hypersensitivity reaction affecting the skin and mucous membranes and should be considered in any child who has been on antiepileptic medication. A case of Stevens Johnson Syndrome and hepatitis following treatment with sodium valproate is presented. A 2 year old female pediatric patient suffering from atonic seizures and myoclonic seizures was treated with sodium valproate monotherapy. The patient reported skin peeling and rash since 15 days and yellowish discoloration of sclera since 7 days. Her laboratory investigations revealed abnormal hemoglobin levels, blood urea and liver function. Based on physical examination and laboratory findings it was diagnosed that she was suffering from sodium valproate induced Stevens Johnson Syndrome with hepatitis. The score of toxic epidermal necrosis (SCORTEN criteria score was 1. She was treated with antihistamines, iron folic acid and topical liquid paraffin lotion.

    This report summarizes the Electromagnetic Interference (EMI) testing of the Johnson Noise Thermometry System developed at ORNL. The EMI performance is very important for Johnson Noise Thermometry because it requires accurate measurement of a very small noise signal that is amplified 10,000 times. Any interference in the form on pickup from external signal sources from such as fluorescent lighting ballasts, motors, etc. can skew the measurement. Testing is therefore very important in determining the effects of these external noise sources. Results from testing in several environments with various sources of EMI are presented here.

  18. Zero-point energy in the Johnson noise of resistors: Is it there?

    CERN Document Server

    Kish, Laszlo B

    2015-01-01

    There is a longstanding debate about the zero-point term in the Johnson noise voltage of a resistor: Is it indeed there or is it only an experimental artifact due to the uncertainty principle for phase-sensitive amplifiers? We show that, when the zero-point term is measured by the mean energy and force in a shunting capacitor and, if these measurements confirm its existence, two types of perpetual motion machines could be constructed. Therefore an exact quantum theory of the Johnson noise must include also the measurement system used to evaluate the observed quantities. The results have implications also for phenomena in advanced nanotechnology.

  19. Multilevel sequential Monte Carlo samplers

    KAUST Repository

    Beskos, Alexandros

    2016-08-29

    In this article we consider the approximation of expectations w.r.t. probability distributions associated to the solution of partial differential equations (PDEs); this scenario appears routinely in Bayesian inverse problems. In practice, one often has to solve the associated PDE numerically, using, for instance finite element methods which depend on the step-size level . hL. In addition, the expectation cannot be computed analytically and one often resorts to Monte Carlo methods. In the context of this problem, it is known that the introduction of the multilevel Monte Carlo (MLMC) method can reduce the amount of computational effort to estimate expectations, for a given level of error. This is achieved via a telescoping identity associated to a Monte Carlo approximation of a sequence of probability distributions with discretization levels . ∞>h0>h1⋯>hL. In many practical problems of interest, one cannot achieve an i.i.d. sampling of the associated sequence and a sequential Monte Carlo (SMC) version of the MLMC method is introduced to deal with this problem. It is shown that under appropriate assumptions, the attractive property of a reduction of the amount of computational effort to estimate expectations, for a given level of error, can be maintained within the SMC context. That is, relative to exact sampling and Monte Carlo for the distribution at the finest level . hL. The approach is numerically illustrated on a Bayesian inverse problem. © 2016 Elsevier B.V.

  20. Equilibrium Statistics: Monte Carlo Methods

    Science.gov (United States)

    Kröger, Martin

    Monte Carlo methods use random numbers, or ‘random’ sequences, to sample from a known shape of a distribution, or to extract distribution by other means. and, in the context of this book, to (i) generate representative equilibrated samples prior being subjected to external fields, or (ii) evaluate high-dimensional integrals. Recipes for both topics, and some more general methods, are summarized in this chapter. It is important to realize, that Monte Carlo should be as artificial as possible to be efficient and elegant. Advanced Monte Carlo ‘moves’, required to optimize the speed of algorithms for a particular problem at hand, are outside the scope of this brief introduction. One particular modern example is the wavelet-accelerated MC sampling of polymer chains [406].

    We further study the validity of the Monte Carlo Hamiltonian method. The advantage of the method,in comparison with the standard Monte Carlo Lagrangian approach, is its capability to study the excited states. Weconsider two quantum mechanical models: a symmetric one V(x) = |x|/2; and an asymmetric one V(x) = ∞, forx < 0 and V(x) = x, for x ≥ 0. The results for the spectrum, wave functions and thermodynamical observables are inagreement with the analytical or Runge-Kutta calculations.

    The Proton Upset Monte Carlo Simulation (PROPSET) program calculates the frequency of on-orbit upsets in computer chips (for given orbits such as Low Earth Orbit, Lunar Orbit, and the like) from proton bombardment based on the results of heavy ion testing alone. The software simulates the bombardment of modern microelectronic components (computer chips) with high-energy (.200 MeV) protons. The nuclear interaction of the proton with the silicon of the chip is modeled and nuclear fragments from this interaction are tracked using Monte Carlo techniques to produce statistically accurate predictions.

  3. THE BIBLICAL CONTEXT OF SELF-REJECTION MOTIF IN THE PLOT OF IVAN TURGENEV’S “A STRANGE STORY”

    Directory of Open Access Journals (Sweden)

    Vyacheslav M. Golovko

    2016-03-01

    Full Text Available The article studies the functional role of  biblical reminiscence in  Ivan S.  Turgenev’s short novel  “A Strange Story”  (1870. A  pretextual function of  the Bible and interpretations of  certain biblical theses, sayings and maxims are revealed through the artistic analysis of  moral choice of Sophie and the embodiment of the existential motif. In the ethics of selfexpression the main character of the short novel relies on the Old Testament dogmas and evangelical preaching as well as asserts her own understanding of  the necessity of  self-renunciation in  the  name of  implementation of  the  moral ideal. Sophie’s moral views despite being formed under the infl uence of  religious ethics are not limited by  the very ethics. Her faith in Christ is accompanied with the consciousness of her duty to people. The biblical ethics of self-dedication is based on antinomy of self-obsession and renunciation of  one’s own self. The personal is  sacrifi ced for the sake of  the  public. This unites Sophie with the selfl ess girls, participants of  the populist movement, and describes the world perception of  a  new person of the watershed times in the “national history”.

    2016-01-01

    The RGB Bayer filter system consists of a mosaic of R, G , and B filters on the grid of the photo sensors which typical commercial DSLR (Digital Single Lens Reflex) cameras and CCD cameras are equipped with. Lot of unique astronomical data obtained using an RGB Bayer filter system are available, including transient objects, e.g. supernovae, variable stars, and solar system bodies. The utilization of such data in scientific research requires that reliable photometric transformation methods are available between the systems. In this work, we develop a series of equations to convert the observed magnitudes in the RGB Bayer filter system (RB,GB , and BB) into the Johnson-Cousins BVR filter system (BJ,VJ , and RC). The new transformation equations derive the calculated magnitudes in the Johnson-Cousins filters (BJcal,VJcal , and RCcal) as functions of RGB magnitudes and colors. The mean differences between the transformed magnitudes and original magnitudes, i.e. the residuals, are Δ (BJ -BJcal) = 0.064 mag, Δ (VJ -VJcal) = 0.041 mag, and Δ (RC -RCcal) = 0.039 mag. The calculated Johnson-Cousins magnitudes from the transformation equations show a good linear correlation with the observed Johnson-Cousins magnitudes.

  10. Investigation of Monnose-Binding Lectin gene Polymorphism in Patients with Erythema Multiforme, Stevens-Johnson Syndrome and Stevens-Johnson Syndrome/Toxic Epidermal Necrolysis Overlap Syndrome

    Directory of Open Access Journals (Sweden)

    Sevil Toka

    2012-09-01

    Full Text Available Objective: Monnose-Binding lectin (MBL appears to play an important role in the immune system. The genetic polymorphisms in the MBL2 gene can result in a reduction of serum levels, leading to a predisposition to recurrent infection. The aim of this study is to investigate the influence of a polymorphism in codon 54 of the MBL2 gene on the susceptibility to Erythema Multiforme, Stevens-Johnson Syndrome and Stevens-Johnson Syndrome/Toxic Epidermal Necrolysis Overlap Syndrome (EM, SJS and SJS/TEN overlap syndrome. Material and Methods: Our study included 64 patients who were clinically and/or histopathologically diagnosed with EM, SJS, and SJS/TEN overlap syndrome and 66 healthy control subjects who were genotyped for the MBL2 gene codon 54 polymorphism using the PCR-RFLP method. For all statistical analyses, the level of significance was set at p<0.05. Results: The prevalence of the B allele was 18% in the EM, SJS and SJS/TEN patient groups and 13% in the control group. No significant differences in allele frequencies of any polymorphism were observed between the patient and control groups, although the B allele was more frequent in the patient groups (p=0.328.Conclusion: Our results provide no evidence of a relationship between MBL2 gene codon 54 polymorphism and the susceptibility to EM, SJS and SJS/TEN overlap syndrome. However, these findings should be confirmed in studies with a larger sample size.

  11. Density matrix quantum Monte Carlo

    CERN Document Server

    Blunt, N S; Spencer, J S; Foulkes, W M C

    2013-01-01

    This paper describes a quantum Monte Carlo method capable of sampling the full density matrix of a many-particle system, thus granting access to arbitrary reduced density matrices and allowing expectation values of complicated non-local operators to be evaluated easily. The direct sampling of the density matrix also raises the possibility of calculating previously inaccessible entanglement measures. The algorithm closely resembles the recently introduced full configuration interaction quantum Monte Carlo method, but works all the way from infinite to zero temperature. We explain the theory underlying the method, describe the algorithm, and introduce an importance-sampling procedure to improve the stochastic efficiency. To demonstrate the potential of our approach, the energy and staggered magnetization of the isotropic antiferromagnetic Heisenberg model on small lattices and the concurrence of one-dimensional spin rings are compared to exact or well-established results. Finally, the nature of the sign problem...

  12. Efficient kinetic Monte Carlo simulation

    Science.gov (United States)

    Schulze, Tim P.

    2008-02-01

    This paper concerns kinetic Monte Carlo (KMC) algorithms that have a single-event execution time independent of the system size. Two methods are presented—one that combines the use of inverted-list data structures with rejection Monte Carlo and a second that combines inverted lists with the Marsaglia-Norman-Cannon algorithm. The resulting algorithms apply to models with rates that are determined by the local environment but are otherwise arbitrary, time-dependent and spatially heterogeneous. While especially useful for crystal growth simulation, the algorithms are presented from the point of view that KMC is the numerical task of simulating a single realization of a Markov process, allowing application to a broad range of areas where heterogeneous random walks are the dominate simulation cost.

    Tutter, Adele

    2011-06-01

    Philip Johnson's masterpiece--the Glass House--is compared to a dream and conceptualized as containing encrypted and embedded representations of the self. Freud's masterpiece--The Interpretation of Dreams--is the theoretical and methodological model for this approach to design-as-dream. Drawing on Johnson's words and forms set in biographical, historical, and cultural context, interpretive paths are traced from manifest design elements of the Glass House to overdetermined latent meanings, yielding new and surprising insights into the Glass House, its elusive architect, and the process of its design. A mirror that reflects an image, a lens that focuses it, and a prism that reveals its components, the Glass House turns a lucid eye onto its maker.

    Full Text Available Minocycline is an antibiotic of tetracycline derivatives that is commonly used in the treatment of moderate to severe acne vulgaris. It has been reported to cause rare adverse events from mild cutaneous eruption to severe forms including drug-induced lupus, serum sickness-like reaction, and hypersensitivity reactions, etc. The risks of adverse events attributed to minocycline have not been ascertained reliably and there are concerns about the safety of minocycline which could possibly result in life-threatening events such as the Stevens-Johnson syndrome. Here we demonstrate an unusual case of Stevens-Johnson syndrome in conjunction with bilateral parotitis after the intake of minocycline in a Korean boy suggesting discreet use of the drug.

    Stevens-Johnson syndrome (SJS) is a severe cutaneous reaction seen rarely in clinical practice. Most often, it occurs as an adverse reaction to certain drugs. When it affects children at a very young age, arrested tooth root development may also be seen. We present a case of a 13 year old boy who suffered from SJ syndrome at the age of 7 years. Incomplete root development was observed in all teeth, as demonstrated by panaromic radiography. Clinical features of this condition and its management are further discussed. We aim to emphasise on the need for dental practitioners to be aware of the potential dental complications of SJS and enable them to recognise and manage the condition at the earliest so as to avoid any undesirable sequelae. Key words:Adverse drug reaction, amoxycillin, arrested root development, Stevens-Johnson syndrome. PMID:27703617

    This latest volume is the 20th in Jeff Seeman's projected 22-volume series of autobiographies of 20th-century organic chemists that began publication in 1990 (Kauffman, G. B. J. Chem. Educ. 1991, 68, A21). Unfortunately, Johnson did not live to see this volume in print. Ted Bartlett and Ray Conrow reviewed the final manuscript, galleys, and page proofs; and Ted Bartlett, Paul Bartlett, John D. Roberts, and Gilbert Stork contributed an epilogue that complements Johnson's own words, adds a warm, personal final touch that he was unable to provide, and incorporates his final research into the volume. Born in New Rochelle, New York, on February 24, 1913, William Summer Johnson attended Amherst College with the aid of a scholarship and various odd jobs such as tending furnace, washing dishes, and playing saxophone in dance bands (he seriously considered becoming a professional musician). Here he became enamored with organic chemistry, which he taught as an instructor for a year after his graduation magna cum laude in 1936. He then worked with a fellowship under Louis Fieser, who sparked his interest in steroids, at Harvard University, from which he received his M.A. (1938) and Ph.D. (1940) degrees. In 1940 Johnson joined the faculty at the University of Wisconsin, where he rose through the ranks, eventually becoming Homer Adkins Professor of Chemistry (1954-60). He began the total synthesis of steroids, the main subject of his life's work, "which soon proved to be the hottest synthetic target of the time". In 1960 he accepted an invitation to become head of and to upgrade the Stanford University Chemistry Department. With faculty recruiting as his primary concern, he was able to add Carl Djerassi, Paul J. Flory, Harden M. McConnell, Henry Taube, and Eugene E. van Tamelen to the department, resulting in its spectacular rise from 15th to 5th place in the nation. He remained at Stanford for the rest of his career, serving as department head for nine years. He died at the

    Water quality of streams in Johnson County, Kansas was evaluated from October 2002 through December 2007 in a cooperative study between the U.S. Geological Survey and the Johnson County Stormwater Management Program. Water quality at 42 stream sites, representing urban and rural basins, was characterized by evaluating benthic macroinvertebrates, water (discrete and continuous data), and/or streambed sediment. Point and nonpoint sources and transport were described for water-quality constituents including suspended sediment, dissolved solids and major ions, nutrients (nitrogen and phosphorus), indicator bacteria, pesticides, and organic wastewater and pharmaceutical compounds. The information obtained from this study is being used by city and county officials to develop effective management plans for protecting and improving stream quality.

    2014-02-01

    The objective of this project was to evaluate the use of the Johnson-Cook strength and failure models in an adiabatic finite element model to simulate the puncture of 7075- T651 aluminum plates that were studied as part of an ASC L2 milestone by Corona et al (2012). The Johnson-Cook model parameters were determined from material test data. The results show a marked improvement, in particular in the calculated threshold velocity between no puncture and puncture, over those obtained in 2012. The threshold velocity calculated using a baseline model is just 4% higher than the mean value determined from experiment, in contrast to 60% in the 2012 predictions. Sensitivity studies showed that the threshold velocity predictions were improved by calibrating the relations between the equivalent plastic strain at failure and stress triaxiality, strain rate and temperature, as well as by the inclusion of adiabatic heating.

    2012-05-01

    This thesis presents Monte Carlo methods for simulations of phase behaviors of Lennard-Jones fluids. The isobaric-isothermal (NPT) ensemble and Gibbs-NPT ensemble are introduced in detail. NPT ensemble is employed to determine the phase diagram of pure component. The reduced simulation results are verified by comparison with the equation of state by by Johnson et al. and results with L-J parameters of methane agree considerably with the experiment measurements. We adopt the blocking method for variance estimation and error analysis of the simulation results. The relationship between variance and number of Monte Carlo cycles, error propagation and Random Number Generator performance are also investigated. We review the Gibbs-NPT ensemble employed for phase equilibrium of binary mixture. The phase equilibrium is achieved by performing three types of trial move: particle displacement, volume rearrangement and particle transfer. The simulation models and the simulation details are introduced. The simulation results of phase coexistence for methane and ethane are reported with comparison of the experimental data. Good agreement is found for a wide range of pressures. The contribution of this thesis work lies in the study of the error analysis with respect to the Monte Carlo cycles and number of particles in some interesting aspects.

    Stormwater runoff is a leading contributor to pollution in streams, rivers, and lakes in Johnson County, Kansas, and nationwide. Because stormwater runoff contains pollutants from many different sources, decreasing pollution from stormwater runoff is a challenging task. It requires cooperation from residents, businesses, and municipalities. An important step in protecting streams from stormwater pollution is understanding watershed processes, stormwater characteristics, and their combined effects on streams and water quality.

    Stevens-Johnson syndrome (SJS) is a severe cutaneous eruption that most often appears as an adverse reaction to a medication. There have been 21 reported cases of atypical erythema multiforme, toxic epidermal necrolysis, and SJS arising in patients receiving radiation therapy in addition to phenytoin, phenobarbital, or carbamazepine. We report the second case of SJS resulting from concomitant phenobarbital and radiation therapy, in which the eruption was limited to the sites of radiation, which were multiple.

    Full Text Available Stevens-Johnson syndrome (SJS is an immune complex mediated hypersensitivity complex that typically involves the skin and the mucous membranes. Various etiologic factors (e.g., infection, drugs and malignancies have been implicated as causes of Stevens-Johnson syndrome. However, as many as half of the cases are idiopathic. Bastuji and Roujeau proposed that the denomination of Stevens-Johnson syndrome should be used for a syndrome characterized by mucous membrane erosions and widespread small blisters that arise on erythematous or purpuric maculae that are different from classic targets. In this case report, a 6 year old girl who was administered a cough syrup (containing bromhexine, guaiphenesin, diphenhydramine and phenylephrine and amoxycillin and clavulanic acid dispersible tablet for the treatment of cough developed pruritic skin eruptions all over the body along with painful erosions on the tongue, buccal mucosa, genital and anal mucosa. A diagnosis of Stevens-Johnson syndrome was made. Amoxycillin and clavulanic acid combination was identified as the culprit based on the temporal relationship between the drug administration and the appearance of the rashes and based on a number of SJS reports implicating amoxycillin and clavulanic acid having been published before. The cough syrup and amoxycillin and clavulanic acid combination tablets were immediately stopped. Symptomatic treatment was administered. The child improved and was later discharged. Causality assessment using Naranjo adverse drug reaction probability scale revealed that amoxycillin and clavulanic acid combination was a possible cause for the harmful cutaneous adverse reaction with a score of 4.

    Objective: To analyze the wild marigold [(Tagetes minuta L.)(T. minuta)] leaf extract with respect to phytochemicals and allelopathic activity. Methods: The aqueous extracts of T. minuta leaves at concentrations of 50%, 75% and 100% were prepared. Preliminary phytochemical analysis was carried out and then allelopathic ef ect of T. minuta on root length, shoot length, germination, fresh and dry weight of Johnson grass and Sun spurge was tested on i lter paper and in soil.Results: Qualitative phytochemical analysis showed the presence of alkaloids, tannins, saponins, l avonoides and terpenoids. The higher concentrations proved to be signii cantly ef ective in reducing almost all the parameters of Sun spurge and Johnson grass in i lter paper bioassay. Supplemented with the soil, all concentrations of leaf extract showed reduction in germination, root and shoot growth, fresh and dry weight of Sun spurge; however, 100% concentration signii cantly reduced the germination of Johnson grass. Conclusions: This study suggests that marigold allelochemicals can be used as an integrated weed management for the production of better crop yield.

    A 48-year-old woman was hospitalized with the diagnosis of hepatitis. She presented with symptoms of jaundice, headache, elevated bilirubin, and elevated hepatic enzymes. She related a recent episode of a bronchial infection that was treated during the previous eight days with paracetamol (500mg, 2 doses only), chlorpheniramine, betamethasone and clindamycin. After an initial clinical and laboratorial improvement, she began to complain of pruritus of the palms and soles. Thereafter, vesicles evolving to blisters developed and a deterioration of her general health ensued. Serologies for hepatitis A, B, and C viruses were negative. Intrahepatic cholestasis and Stevens Johnson Syndrome (SJS) were the final diagnosis. The association of the Stevens Johnson Syndrome and intrahepatic cholestasis simultaneously, related to adverse drug reactions, is very rare. The drugs reportedly involved are mainly antibiotics, such as ampicillin, vancomycin, amoxicillin/clavulinic acid and erythromycin. Other drugs involved are non-steroidal anti-inflamatory drugs, such as mefenamic acid, ibuprofen, and sulindac. The reactions can be minor or severe and can even cause death, an outcome that has been reported in patients of all races and ethnic groups, but appears to be more rare in patients of Latin origin. We present a discussion of this case and review the main characteristics of the Stevens Johnson Syndrome.

  17. Zero-point term and quantum effects in the Johnson noise of resistors: a critical appraisal

    Science.gov (United States)

    Kish, Laszlo B.; Niklasson, Gunnar A.; Granqvist, Claes G.

    2016-05-01

    There is a longstanding debate about the zero-point term in the Johnson noise voltage of a resistor. This term originates from a quantum-theoretical treatment of the fluctuation-dissipation theorem (FDT). Is the zero-point term really there, or is it only an experimental artifact, due to the uncertainty principle, for phase-sensitive amplifiers? Could it be removed by renormalization of theories? We discuss some historical measurement schemes that do not lead to the effect predicted by the FDT, and we analyse new features that emerge when the consequences of the zero-point term are measured via the mean energy and force in a capacitor shunting the resistor. If these measurements verify the existence of a zero-point term in the noise, then two types of perpetual motion machines can be constructed. Further investigation with the same approach shows that, in the quantum limit, the Johnson-Nyquist formula is also invalid under general conditions even though it is valid for a resistor-antenna system. Therefore we conclude that in a satisfactory quantum theory of the Johnson noise, the FDT must, as a minimum, include also the measurement system used to evaluate the observed quantities. Issues concerning the zero-point term may also have implications for phenomena in advanced nanotechnology.

En el año 2006, el organismo encargado de su custodia, el Instituto de Patrimonio Cultural del Ministerio de Cultura, ejecutó tres etapas de exploración arqueológica, que abarcaron las áreas Traspatio, Patio Central y las Naves Este y Oeste de la edificación. Este trabajo reseña el análisis de la documentación arqueológica obtenida en el sitio, a partir de la realización de dicho proyecto, denominado EACUSAC (Estudio Arqueológico del Cuartel San Carlos, que representa además, la tercera campaña realizada en el sitio. La importancia de este yacimiento histórico, radica en su participación en los acontecimientos que propiciaron conflictos de poder durante el surgimiento de la República y en los sucesos políticos del siglo XX. De igual manera, se encontró en el sitio una amplia muestra de materiales arqueológicos que reseñan un estilo de vida cotidiana militar, así como las dinámicas sociales internas ocurridas en el San Carlos, como lugar estratégico para la defensa de los diferentes regímenes que atravesó el país, desde la época del imperialismo español hasta nuestros días.

    The behavior of the one-dimensional random-force-driven Burgers equation is investigated in the path integral formalism on a discrete space-time lattice. We show that by means of Monte Carlo methods one may evaluate observables, such as structure functions, as ensemble averages over different field realizations. The regularization of shock solutions to the zero-viscosity limit (Hopf-equation) eventually leads to constraints on lattice parameters required for the stability of the simulations. Insight into the formation of localized structures (shocks) and their dynamics is obtained. (orig.)

    2013-01-01

    Modern cancer treatment relies on Monte Carlo simulations to help radiotherapists and clinical physicists better understand and compute radiation dose from imaging devices as well as exploit four-dimensional imaging data. With Monte Carlo-based treatment planning tools now available from commercial vendors, a complete transition to Monte Carlo-based dose calculation methods in radiotherapy could likely take place in the next decade. Monte Carlo Techniques in Radiation Therapy explores the use of Monte Carlo methods for modeling various features of internal and external radiation sources, including light ion beams. The book-the first of its kind-addresses applications of the Monte Carlo particle transport simulation technique in radiation therapy, mainly focusing on external beam radiotherapy and brachytherapy. It presents the mathematical and technical aspects of the methods in particle transport simulations. The book also discusses the modeling of medical linacs and other irradiation devices; issues specific...

    We present a new hybrid Monte Carlo method for 1-D equilibrium diffusion problems in which the radiation field coexists with matter in local thermodynamic equilibrium. This method, the Equilibrium Discrete Diffusion Monte Carlo (EqDDMC) method, combines Monte Carlo particles with spatially discrete diffusion solutions. We verify the EqDDMC method with computational results from three slab problems. The EqDDMC method represents an incremental step toward applying this hybrid methodology to non-equilibrium diffusion, where it could be simultaneously coupled to Monte Carlo transport.

    While the Quasi-Monte Carlo method of numerical integration achieves smaller integration error than standard Monte Carlo, its use in particle physics phenomenology has been hindered by the abscence of a reliable way to estimate that error. The standard Monte Carlo error estimator relies on the assumption that the points are generated independently of each other and, therefore, fails to account for the error improvement advertised by the Quasi-Monte Carlo method. We advocate the construction o...

    2015-01-01

    The Kirchhoff-Law-Johnson-Noise (KLJN) secure key exchange system has been introduced as a simple, very low cost and efficient classical physical alternative to quantum key distribution systems. The ideal system uses only a few electronic components - identical resistor pairs, switches and interconnecting wires - to guarantee perfectly protected data transmission. We show that a generalized KLJN system can provide unconditional security even if it is used with significantly less limitations. The more universal conditions ease practical realizations considerably and support more robust protection against attacks. Our theoretical results are confirmed by numerical simulations.

    BACKGROUND:Dubin-Johnson syndrome (DJS) is a rare clinical entity. We describe a case of DJS complicated by systemic lupus erythematosus (SLE). METHODS:A case of congenital hyperbilirubinemia with SLE was evaluated systematically including review of history, physical examination for the stigmata of chronic liver disease, and other investigations. RESULT:Liver biopsy revealed a black liver with preserved architecture suggestive of DJS. CONCLUSIONS:SLE may develop in DJS. The relationship between DJS and SLE in this case is most likely a chance occurrence.

    Dubin-Johnson syndrome (DJS) is an autosomal recessive inherited disorder characterized by conjugated hyperbilirubinemia. Neonatal-onset DJS is rare. It is caused by dysfunction of adenosine triphosphate-binding cassette, sub-family C, member 2 (ABCC2). We found a novel compound heterozygous mutation of DJS-related gene: W709R (T2145C): a missense mutation in exon 17, and R768W (C2302T), a missense mutation in exon 18. Serum diglucuronosyl bilirubin/monoglucuronosyl bilirubin ratio was high. ABCC2 may excrete diglucuronosyl bilirubin preferentially over monoglucuronosyl bilirubin.

    We introduce a protocol with a reconfigurable filter system to create non-overlapping single loops in the smart power grid for the realization of the Kirchhoff-Law-Johnson-(like)-Noise secure key distribution system. The protocol is valid for one-dimensional radial networks (chain-like power line) which are typical of the electricity distribution network between the utility and the customer. The speed of the protocol (the number of steps needed) versus grid size is analyzed. When properly generalized, such a system has the potential to achieve unconditionally secure key distribution over the smart power grid of arbitrary geometrical dimensions.

    The primal-dual scheme has been used to provide approximation algorithms for many problems. Goemans and Williamson gave a (2-1/(n-1))-approximation for the Prize-Collecting Steiner Tree Problem that runs in O(n^3 log n) time. it applies the primal-dual scheme once for each of the n vertices of the graph. Johnson, Minkoff and Phillips proposed a faster implementation of Goemans and Williamson's algorithm. We give a proof that the approximation ratio of this implementation is exactly 2.

    A simple and general proof is given for the information theoretic (unconditional) security of the Kirchhoff-law-Johnson-noise key exchange system under practical conditions. The unconditional security for ideal circumstances, which is based on the second law of thermodynamics, is found to prevail even under slightly non-ideal conditions. This security level is guaranteed by the continuity of functions describing classical physical linear, as well as stable non-linear, systems. Even without privacy amplification, Eve's probability for successful bit guessing is found to converge toward 0.5—i.e., the perfect security level—when ideal conditions are approached.

    To understand theoretically the flow properties of physiological fluids we have considered as a model the peristaltic motion of a Johnson-Segalman fluid in a tube with a sinusoidal wave traveling down its wall. The perturbation solution for the stream function is obtained for large wavelength and small Weissenberg number. The expressions for the axial velocity, pressure gradient, and pressure rise per wavelength are also constructed. The general solution of the governing nonlinear partial differential equation is given using a transformation method. The numerical solution is also obtained and is compared with the perturbation solution. Numerical results are demonstrated for various values of the physical parameters of interest. (orig.)

    Stevens-Johnson syndrome (SJS) is a serious and potentially life-threatening disease. Vanishing bile duct syndrome (VBDS) is a rare cause of progressive cholestasis. Both syndromes are mostly related with drugs. We report a case of a patient withciprofloxacin-induced SJS and acute onset of VBDS,and reviewed the related literature. It is the first case of ciprofloxacin-induced VBDS successfully treatedwith tacrolimus. This case reminds physicians of the importance of drug reactions, their severity, techniques for diagnosis and methods of management.

    Full Text Available Nevirapine, a non-nucleoside reverse transcriptase inhibitor (NNRTI, is widely prescribed as a part of the combination therapy of human immunodeficiency virus (HIV infection because of its efficacy and good tolerability. Here, we report a case of Stevens-Johnson syndrome (SJS secondary to nevirapine. The patient had a diffuse, exfoliating exanthema with generalized bullous eruptions that involved the face, trunk and both extremities with elevated hepatic alanine aminotransferase and aspartate aminotransferase enzyme activities. The condition improved with stoppage of nevirapine-based highly active antiretroviral therapy (HAART regimen, so we attributed this adverse event to nevirapine. A strict vigilance of adverse drug reaction is required in HAART.

    K. David Newell; Timothy R. Carr

    2007-03-31

    The Johnson County Landfill in Shawnee, KS is operated by Deffenbaugh Industries and serves much of metropolitan Kansas City. Refuse, which is dumped in large plastic-underlined trash cells covering several acres, is covered over with shale shortly after burial. The landfill waste, once it fills the cell, is then drilled by Kansas City LFG, so that the gas generated by anaerobic decomposition of the refuse can be harvested. Production of raw landfill gas from the Johnson County landfill comes from 150 wells. Daily production is approximately 2.2 to 2.5 mmcf, of which approximately 50% is methane and 50% is carbon dioxide and NMVOCs (non-methane volatile organic compounds). Heating value is approximately 550 BTU/scf. A upgrading plant, utilizing an amine process, rejects the carbon dioxide and NMVOCs, and upgrades the gas to pipeline quality (i.e., nominally a heating value >950 BTU/scf). The gas is sold to a pipeline adjacent to the landfill. With coal-bearing strata underlying the landfill, and carbon dioxide a major effluent gas derived from the upgrading process, the Johnson County Landfill is potentially an ideal setting to study the feasibility of injecting the effluent gas in the coals for both enhanced coalbed methane recovery and carbon sequestration. To these ends, coals below the landfill were cored and then were analyzed for their thickness and sorbed gas content, which ranged up to 79 scf/ton. Assuming 1 1/2 square miles of land (960 acres) at the Johnson County Landfill can be utilized for coalbed and shale gas recovery, the total amount of in-place gas calculates to 946,200 mcf, or 946.2 mmcf, or 0.95 bcf (i.e., 985.6 mcf/acre X 960 acres). Assuming that carbon dioxide can be imbibed by the coals and shales on a 2:1 ratio compared to the gas that was originally present, then 1682 to 1720 days (4.6 to 4.7 years) of landfill carbon dioxide production can be sequestered by the coals and shales immediately under the landfill.

    This work is concerned with the peristaltic transport of the Johnson-Segalman fluid in an asymmetric channel with convective boundary conditions. The mathematical modeling is based upon the conservation laws of mass, linear momentum, and energy. The resulting equations are solved after long wavelength and low Reynolds number are used. The results for the axial pressure gradient, velocity, and temperature profiles are obtained for small Weissenberg number. The expressions of the pressure gra-dient, velocity, and temperature are analyzed for various embedded parameters. Pumping and trapping phenomena are also explored.

On the other hand it is reconsidered through the reflections of the Triestine psychoanalyst Paolo Fonda: the absence of conscious semiosis is the product of intense fears and desires that pervade the construction of ethnic identities in Trieste.

    These are slides from a presentation for Parallel Summer School at Los Alamos National Laboratory. Solving discretized partial differential equations (PDEs) of interest can require a large number of computations. We can identify concurrency to allow parallel solution of discrete PDEs. Simulated particles histories can be used to solve the Boltzmann transport equation. Particle histories are independent in neutral particle transport, making them amenable to parallel computation. Physical parameters and method type determine the data dependencies of particle histories. Data requirements shape parallel algorithms for Monte Carlo. Then, Parallel Computational Physics and Parallel Monte Carlo are discussed and, finally, the results are given. The mesh passing method greatly simplifies the IMC implementation and allows simple load-balancing. Using MPI windows and passive, one-sided RMA further simplifies the implementation by removing target synchronization. The author is very interested in implementations of PGAS that may allow further optimization for one-sided, read-only memory access (e.g. Open SHMEM). The MPICH_RMA_OVER_DMAPP option and library is required to make one-sided messaging scale on Trinitite - Moonlight scales poorly. Interconnect specific libraries or functions are likely necessary to ensure performance. BRANSON has been used to directly compare the current standard method to a proposed method on idealized problems. The mesh passing algorithm performs well on problems that are designed to show the scalability of the particle passing method. BRANSON can now run load-imbalanced, dynamic problems. Potential avenues of improvement in the mesh passing algorithm will be implemented and explored. A suite of test problems that stress DD methods will elucidate a possible path forward for production codes.

    Full Text Available Carlos Restrepo fue el primer profesor de Patología y un miembro ilustre del grupo de pioneros que fundaron la Facultad de Medicina de la Universidad del Valle. Estos pioneros convergieron en Cali en la década de 1950, en posesión de un espíritu renovador y creativo que emprendió con mucho éxito la labor de cambiar la cultura académica del Valle del Cauca. Ellos encontraron una sociedad apacible, que disfrutaba de la generosidad de su entorno, sin deseos de romper las tradiciones centenarias de estilo de vida sencillo y satisfecho. Cuando los hijos tenían el deseo y la capacidad de seguir estudios universitarios, especialmente en el área de la medicina, la familia los enviaba a climas menos cálidos, que supuestamente favorecían la función cerebral y la acumulación de conocimientos. Los pioneros de la educación médica en el Valle del Cauca, en buena parte reclutados en universidades nacionales y extranjeras, sabían muy bien que el ambiente vallecaucano no impide una formación universitaria de primera clase. Carlos Restrepo era prototipo del espíritu de cambio y formación intelectual de las nuevas generaciones. Lo manifestaba de múltiples maneras, en buena parte con su genio alegre, extrovertido, optimista, de risa fácil y contagiosa. Pero esta fase amable de su personalidad no ocultaba su tarea formativa; exigía de sus discípulos dedicación y trabajo duro, con fidelidad expresados en memorables caricaturas que exageraban su genio ocasionalmente explosivo. El grupo de pioneros se enfocó con un espíritu de total entrega (tiempo completo y dedicación exclusiva y organizó la nueva Facultad en bien definidos y estructurados departamentos: Anatomía, Bioquímica, Fisiología, Farmacología, Patología, Medicina Interna, Cirugía, Obstetricia y Ginecología, Psiquiatría y Medicina Preventiva. Los departamentos integraron sus funciones primordiales en la enseñanza, la investigación y el servicio a la comunidad. El centro

    MC21 is a new Monte Carlo neutron and photon transport code currently under joint development at the Knolls Atomic Power Laboratory and the Bettis Atomic Power Laboratory. MC21 is the Monte Carlo transport kernel of the broader Common Monte Carlo Design Tool (CMCDT), which is also currently under development. The vision for CMCDT is to provide an automated, computer-aided modeling and post-processing environment integrated with a Monte Carlo solver that is optimized for reactor analysis. CMCDT represents a strategy to push the Monte Carlo method beyond its traditional role as a benchmarking tool or ''tool of last resort'' and into a dominant design role. This paper describes various aspects of the code, including the neutron physics and nuclear data treatments, the geometry representation, and the tally and depletion capabilities.

    2008-01-01

    A poster entitled "Space Medicine - A New Role for Clinical Pharmacists" was presented in December 2001 highlighting an up-and-coming role for pharmacists at the Johnson Space Center (JSC) in Houston, Texas. Since that time, the operational need for the pharmacy profession has expanded with the administration s decision to open a pharmacy on site at JSC to complement the care provided by the Flight Medicine and Occupational Medicine Clinics. The JSC Pharmacy is a hybrid of traditional retail and hospital pharmacy and is compliant with the ambulatory care standards set forth by the Joint Commission. The primary charge for the pharmacy is to provide medication management for JSC. In addition to providing ambulatory care for both clinics, the pharmacists also practice space medicine. A pharmacist had been involved in the packing of both the Space Shuttle and International Space Station Medical Kits before the JSC Pharmacy was established; however, the role of the pharmacist in packing medical kits has grown. The pharmacists are now full members of the operations team providing consultation for new drug delivery systems, regulations, and patient safety issues. As the space crews become more international, so does the drug information provided by the pharmacists. This presentation will review the journey of the JSC Pharmacy as it celebrated its five year anniversary in April of 2008. The implementation of the pharmacy, challenges to the incorporation of the pharmacy into an existing health-care system, and the current responsibilities of a pharmacist at the Johnson Space Center will be discussed.

    This report outlines the tasks and objectives completed during a co-operative education tour with National Aeronautics and Space Association (NASA) at the Johnson Space Center in Houston, Texas. I worked for the Attitude & Pointing group of the Flight Dynamics Division within the Mission Operations Directorate at Johnson Space Center. NASA's primary mission is to support and expand the various ongoing space exploration programs and any research and development activities associated with it. My primary project required me to develop and a SharePoint web application for my group. My secondary objective was to become familiar with the role of my group which was primarily to provide spacecraft attitude and line of sight determination, including Tracking and Data Relay Satellite (TDRS) communications coverage for various NASA, International, and commercial partner spacecraft. My projects required me to become acquainted with different software systems, fundamentals of aerospace engineering, project management, and develop essential interpersonal communication skills. Overall, I accomplished multiple goals which included laying the foundations for an updated SharePoint which will allow for an organized platform to communicate and share data for group members and external partners. I also successfully learned about the operations of the Attitude & Pointing Group and how it contributes to the Missions Operations Directorate and NASA's Space Program as a whole

    Full Text Available TS-1 is an oral fluoropyrimidine anticancer drug that contains tegafur, gimeracil, and oteracil. A 78-year-old Japanese male who was diagnosed with carcinoma of the oral floor (rT4aN0M0 was prescribed a standard dose of TS-1 (80 mg/day. On Day 8 after administration of TS-1, an eruption developed. There was erythema, along with vesicles and erosions involving the lip, face, neck, trunk, limbs, and genitals. The drug-induced lymphocyte stimulation test (DLST for TS-1 was negative on the 23rd day, but positive on the 43rd day (20 days after discontinuing prednisolone. The condition was diagnosed as Stevens–Johnson syndrome due to TS-1 because of the clinical course and laboratory results. This case and 24 cases previously reported in the literature were analyzed. The types of drug eruption were drug-related lupus (9 cases, acral erythema (7 cases, scleroderma-like skin lesion (2 cases, Stevens–Johnson syndrome (2 cases, lichenoid eruption (1 case, purpura (1 case, lichen planus (1 case, erythema multiforme (1 case, hypopigmentation (1 case and toxic epidermal necrolysis (1 case, respectively. In view of the increasing usage of TS-1 in several common cancers, clinicians should be aware of drug eruptions due to TS-1.

    2012-01-01

    The U.S. Environmental Protection Agency (EPA), in accordance with the RE-Powering America's Land initiative, selected the Johnson County Landfill in Shawnee, Kansas, for a feasibility study of renewable energy production. Citizens of Shawnee, city planners, and site managers are interested in redevelopment uses for landfills in Kansas that are particularly well suited for grid-tied solar photovoltaic (PV) installation. This report assesses the Johnson County Landfill for possible grid-tied PV installations and estimates the cost, performance, and site impacts of three different PV options: crystalline silicon (fixed tilt), crystalline silicon (single-axis tracking), and thin film (fixed tilt). Each option represents a standalone system that can be sized to use an entire available site area. In addition, the report outlines financing options that could assist in the implementation of a system. The feasibility of PV systems installed on landfills is highly impacted by the available area for an array, solar resource, operating status, landfill cap status, distance to transmission lines, and distance to major roads. The report findings are applicable to other landfills in the surrounding area.

    This article investigates the impact NBA basketball star Earvin ("Magic") Johnson's HIV disclosure had on changes in demand for HIV counseling and testing services in New York State's 61 Anonymous HIV Counseling and Testing sites. Interrupted time-series analyses were conducted on weekly data from over 34,000 clients seeking anonymous HIV counseling and testing services from January 1991 to June 1992, to determine whether demand for these services changed as a result of the disclosure. Results indicated that immediately following the HIV disclosure, there was a substantial increase in service demand, which transcended all sex, race, age, and most HIV risk-related boundaries. Seven months later, demand had not returned to pre-disclosure levels. The strong impact on females, coupled with additional data analyses in obstetrical settings, suggests that previous research has been too narrow in focus, and that the effect of Johnson's HIV disclosure has been enhanced, in part, by the publicity surrounding his wife and baby. The importance of harnessing the heightened public awareness of celebrity HIV disclosures is discussed.

  9. A modified Johnson-Cook constitutive relationship for a rare-earth containing magnesium alloy

    2013-01-01

    Lightweight magnesium alloy has recently attracted a considerable interest in the automotive and aerospace industries to improve fuel efficiency and reduce CO2 emissions via the weight reduction of vehicles. Rare-earth (RE) element addition can re-markably improve the mechanical properties of magnesium alloys through weakening crystallographic textures associated with the strong mechanical anisotropy and tension-compression yield asymmetry. While the addition of RE elements sheds some light on the alteration in the mechanical anisotropy, available information on the constitutive relationships used to describe the flow behavior of RE-containing magnesium alloys is limited. To establish such a constitutive relationship, uniaxial compressive deformation tests were first conducted on an extruded Mg-10Gd-3Y-0.5Zr (GW103K) magnesium alloy at the strain rates ranging from 1×10-1 to 1×10-4 s-1 at room temperature. A modified Johnson-Cook constitutive equation based on a recent strain hardening equation was proposed to predict the flow stresses of GW103K alloy. Comparisons between the predicted and experimental results showed that the modified Johnson-Cook constitutive equation was able to predict the flow stresses of the RE-containing magnesium alloy fairly accurately with a standard deviation of about 1.8%.

    The $RGB$ Bayer filter system consists of mosaic $R$, $G$, and $B$ filters on the grid of photo sensors which typical commercial DSLR (Digital Single Lens Reflex) cameras and CCD cameras are equipped with. Many unique astronomical data obtained using a $RGB$ Bayer filter system are available, including transient objects, e.g., supernovae, variable stars, and solar system bodies. The utilization of such data in scientific research strongly requires reliable photometry transformation methods. In this work, we develop a series of equations to convert the observed magnitudes in the $RGB$ Bayer filter system ($R_B$, $G_B$, and $B_B$) into the Johnson-Cousins $BVR$ filter system ($B_J$, $V_J$, and $R_C$). The new transformation equations derive the calculated magnitudes in Johnson-Cousins filters ($B_{Jcal}$, $V_{Jcal}$, and $R_{Ccal}$) as functions of magnitudes and colors. The mean differences between the transformed magnitudes and original magnitudes, i.e., the residuals, are $\\Delta(B_J-B_{Jcal})$ = 0.104 mag, ...

    The formation of mild steel (MS) and copper (Cu) explosively formed projectiles (EFPs) was simulated in AUTODYN using both the Johnson-Cook (JC) and modified Johnson-Cook (JCM) constitutive models. The JC model was modified by increasing the hardening constant by 10%. The previously established semi-empirical equations for diameter, length, velocity, and depth of penetration were used to verify the design of the EFP. The length-to-diameter (L/D) ratio of the warhead used in the simulation varied between 1 projectile distortion or breakup for large standoff applications, the design of the EFP warhead was modified to obtain a lower L/D ratio. Simulations from the JC model underestimated the EFP diameter, resulting in an unrealistically elongated projectile. This shortcoming was resolved by employing the JCM model, giving good agreement with the experimental results. The projectile velocity and hole characteristics in 10-mm-thick aluminum target plates were studied for both models. The semi-empirical equations and the JC model overestimated the projectile velocity, whereas the JCM model underestimated the velocity slightly when compared to the experimental results. The depths of penetration calculated by the semi-empirical equations in the aluminum (Al) target plate were 55 and 52 mm for Cu and MS EFPs, respectively.

We argue here that the same remains to be done with the Shore and Johnson 1980 axioms. We arrive to this conclusion by analyzing specific classes of strongly correlated complex systems that await such generalization.

    Significant progress has been made recently in the application of Monte Carlo methods to the study of light nuclei. We review new Green's function Monte Carlo results for the alpha particle, Variational Monte Carlo studies of {sup 16}O, and methods for low-energy scattering and transitions. Through these calculations, a coherent picture of the structure and electromagnetic properties of light nuclei has arisen. In particular, we examine the effect of the three-nucleon interaction and the importance of exchange currents in a variety of experimentally measured properties, including form factors and capture cross sections. 29 refs., 7 figs.

    A new Monte Carlo method termed Comb-like frame Monte Carlo is developed to simulate the soot dynamics. Detailed stochastic error analysis is provided. Comb-like frame Monte Carlo is coupled with the gas phase solver Chemkin II to simulate soot formation in a 1-D premixed burner stabilized flame. The simulated soot number density, volume fraction, and particle size distribution all agree well with the measurement available in literature. The origin of the bimodal distribution of particle size distribution is revealed with quantitative proof.

    We present an efficient method to find minimum energy structures using energy estimates from accurate quantum Monte Carlo calculations. This method involves a stochastic process formed from the stochastic energy estimates from Monte Carlo that can be averaged to find precise structural minima while using inexpensive calculations with moderate statistical uncertainty. We demonstrate the applicability of the algorithm by minimizing the energy of the H2O-OH- complex and showing that the structural minima from quantum Monte Carlo calculations affect the qualitative behavior of the potential energy surface substantially.

We use asynchronous execution schemes with shared memory persistence, and obtain an excellent acceleration. Comparing with single core execution, GPU-accelerated code runs over x100 faster. The CUDA code is provided along with the package that is necessary to execute variational Monte Carlo for a system representing liquid helium-4. The program was benchmarked on several models of Nvidia GPU, including Fermi GTX560 and M2090, and the latest Kepler architecture K20 GPU. Kepler-specific optimization is discussed.

  1. Does Johnson's Prescriptive Approach Still Have a Role to Play in Modern-Day Dictionaries?

    ABSTRACT: Samuel Johnson's dictionary (1755 confirmed both the status of dictionaries as authoritative sources of (linguistic knowledge and the prescriptive approach in lexicography. This approach prevailed for a long time. During the last decades the descriptive approach came to the fore, aptly supported by the increased reliance on lexicographic corpora. Modern-day lexicography has also witnessed the introduction of a third approach, i.e. the proscriptive approach, which includes features of both the prescriptive and the descriptive approach. This article investigates the occurrence of the prescriptive, descriptive and proscriptive approaches in modern-day dictionaries. A distinction is made between dictionaries focusing on language for general purposes and dictionaries focusing on languages for special purposes. It is shown that users rely on dictionaries as prescriptive reference sources and expect lexicographers to provide them with an answer to the specific question that prompted the dictionary consultation process. It is argued that knowledgeable dictionary users must be able to achieve an unambiguous retrieval of information and must be able to rely on the dictionary to satisfy their specific cognitive or communicative needs. Here the proscriptive approach plays an important role.

    2003-01-01

    Full Text Available This paper is devoted to the study of the two-dimensional flow of a Johnson-Segalman fluid in a planar channel having walls that are transversely displaced by an infinite, harmonic travelling wave of large wavelength. Both analytical and numerical solutions are presented. The analysis for the analytical solution is carried out for small Weissenberg numbers. (A Weissenberg number is the ratio of the relaxation time of the fluid to a characteristic time associated with the flow. Analytical solutions have been obtained for the stream function from which the relations of the velocity and the longitudinal pressure gradient have been derived. The expression of the pressure rise over a wavelength has also been determined. Numerical computations are performed and compared to the perturbation analysis. Several limiting situations with their implications can be examined from the presented analysis.

  3. Systematic errors in the correlation method for Johnson noise thermometry: residual correlations due to amplifiers

    CERN Document Server

    Callegaro, Luca; Ortolano, Massimo

    2009-01-01

    Johnson noise thermometers (JNT) measure the equilibrium electrical noise, proportional to thermodynamic temperature, of a sensing resistor. In the correlation method, the same resistor is connected to two amplifiers and a correlation of their outputs is performed, in order to reject amplifiers' noise. Such rejection is not perfect: the residual correlation gives a systematic error in the JNT reading. In order to put an upper limit, or to achieve a correction, for such error, a careful electrical modelling of the amplifiers and connections must be performed. Standard numerical simulation tools are inadequate for such modelling. In literature, evaluations have been performed by the painstaking solving of analytical modelling. We propose an evaluation procedure for the JNT error due to residual correlations which blends analytical and numerical approaches, with the benefits of both: a rigorous and accurate circuit noise modelling, and a fast and flexible evaluation with an user-friendly commercial tool.

    Dubin-Johnson syndrome (DJS) is an autosomal recessive disorder characterised by conjugated hyperbilirubinemia resulting from mutations of ABCC2/MRP2 gene. The beneficial effects of ursodeoxycholic acid (UDCA) and rifampicin were found to be complementary in the treatment of cholestatic liver disease secondary to DJS. We present a case of a young woman with tubercular meningitis. She was started on modified antitubercular therapy in view of conjugated hyperbilirubinemia. However, reinitiation of rifampicin resulted in redevelopment of jaundice. Liver biopsy was suggestive of DJS. The patient was started on rifampicin along with UDCA. There was improvement in hyperbilirubinemia and a full course of antituberculous therapy without further worsening of the disorder was possible. This is a rare case of DJS with tuberculosis, showing beneficial effects of rifampicin and UDCA combination therapy, which so far has been considered doubtful. It is uncertain what the level of efficacy of therapy is in various MRP2 gene mutations.

  5. Is intravenous immunoglobulin effective in toxic epidermal necrolysis and Stevens-Johnson syndrome?

    Directory of Open Access Journals (Sweden)

    Lucas Navajas

    2014-10-01

    Full Text Available Toxic epidermal necrolysis and Stevens-Johnson syndrome are severe cutaneous adverse drug reactions. Intravenous immunoglobulin is described as a therapeutic option, however its use is still controversial. Using Epistemonikos database, which is maintained by screening over 20 databases, we identified six systematic reviews, including 39 primary studies. We combined the evidence using tables for summary of findings, following the GRADE approach, and concluded there is uncertainty about the effects of intravenous immunoglobulin because the certainty of the evidence is very low; it probably leads to important adverse effects; and has high cost. Intravenous immunoglobulin should not be used outside the context of a clinical trial, or only in cases where other treatments have failed and there are no resource constraints.

    The EG6 navigation team at NASA Johnson Space Center, like any team of engineers, interacts with the engineering process from beginning to end; from exploring solutions to a problem, to prototyping and studying the implementations, all the way to polishing and verifying a final flight-ready design. This summer, I was privileged enough to gain exposure to each of these processes, while also getting to truly experience working within a team of engineers. My summer can be broken up into three projects: i) Initial study and prototyping: investigating a manual navigation method that can be utilized onboard Orion in the event of catastrophic failure of navigation systems; ii) Finalizing and verifying code: altering a software routine to improve its robustness and reliability, as well as designing unit tests to verify its performance; and iii) Development of testing equipment: assisting in developing and integrating of a high-fidelity testbed to verify the performance of software and hardware.

    The quality of streams and relations to environmental variables in Johnson County, northeastern Kansas, were evaluated using water, streambed sediment, land use, streamflow, habitat, algal periphyton (benthic algae), and benthic macroinvertebrate data. Water, streambed sediment, and macroinvertebrate samples were collected in March 2007 during base flow at 20 stream sites that represent 11 different watersheds in the county. In addition, algal periphyton samples were collected twice (spring and summer 2007) at one-half of the sites. Environmental data including water and streambed-sediment chemistry data (primarily nutrients, fecal-indicator bacteria, and organic wastewater compounds), land use, streamflow, and habitat data were used in statistical analyses to evaluate relations between biological conditions and variables that may affect them. This report includes an evaluation of water and streambed-sediment chemistry, assessment of habitat conditions, comparison of biological community attributes (such as composition, diversity, and abundance) among sampling sites, placement of sampling sites into impairment categories, evaluation of biological data relative to environmental variables, and evaluation of changes in biological communities and effects of urbanization. This evaluation is useful for understanding factors that affect stream quality, for improving water-quality management programs, and for documenting changing conditions over time. The information will become increasingly important for protecting streams in the future as urbanization continues. Results of this study indicate that the biological quality at nearly all biological sampling sites in Johnson County has some level of impairment. Periphyton taxa generally were indicative of somewhat degraded conditions with small to moderate amounts of organic enrichment. Camp Branch in the Blue River watershed was the only site that met State criteria for full support of aquatic life in 2007. Since 2003

    2009-06-01

    The Johnson-Holmquist ceramic material model has been calibrated and successfully applied to numerically simulate ballistic events using the Lagrangian code EPIC. While the majority of the constants are ``physics'' based, two of the constants for the failed material response are calibrated using ballistic experiments conducted on a confined cylindrical ceramic target. The maximum strength of the failed ceramic is calibrated by matching the penetration velocity. The second refers to the equivalent plastic strain at failure under constant pressure and is calibrated using the dwell time. Use of these two constants in the CTH Eulerian hydrocode does not predict the ballistic response. This difference may be due to the phenomenological nature of the model and the different numerical schemes used by the codes. This paper determines the afore mentioned material constants for SiC suitable for simulating ballistic events using CTH.

    2016-01-25

    We present a Johnson noise thermometry (JNT) system based on an integrated quantum voltage noise source (IQVNS) that has been fully implemented using superconducting circuit technology. To enable precise measurement of Boltzmann's constant, an IQVNS chip was designed to produce intrinsically calculable pseudo-white noise to calibrate the JNT system. On-chip real-time generation of pseudo-random codes via simple circuits produced pseudo-voltage noise with a harmonic tone interval of less than 1 Hz, which was one order of magnitude finer than the harmonic tone interval of conventional quantum voltage noise sources. We estimated a value for Boltzmann's constant experimentally by performing JNT measurements at the temperature of the triple point of water using the IQVNS chip.

    2002-01-01

    An extensive collection of Martian analogue samples housed at the Johnson Space Center is the focus of ongoing research by the JSC Mars soil genesis group and their collaborators. Because the major element composition of Martian meteorites and in situ analyses of Martian soils and rocks indicate that Mars is predominantly an iron-rich basaltic world, the focus of active sample collection and analysis is basaltic materials and their hydrolytic (both aqueous and hydrothermal) and sulfatetic alteration products. Described below are the scope of the JSC Mars analogue sample collection, the characterization process, and plans to incorporate the data into spectral libraries for the Mars 2003 Mars Exploration Rover (MER) and Mars 2005 Mars Reconnaissance Orbiter (MRO) CRISM missions.

    2008-01-01

    This slide presentation reviews the program to assess the possibility of lead paint exposure in the high bays of some of the Johnson Space Center buildings. Some of the buildings in the Manned Space Flight Center (MSC) were built in 1962 and predate any considerations to reduce lead in paints and coatings. There are many of these older buildings that contain open shops and work areas that have open ceilings, These shops include those that had operations that use leaded gasoline, batteries, and lead based paints. Test were planned to be conducted in three phases: (1) Surface Dust sampling, (2) personal exposure montioring, and (3) Ceiling paint Sampling. The results of the first two phases were reviewed. After considering the results of the first two phases, and the problems associated with the retrieval of samples from high ceilings, it was determined that the evaluation of ceiling coatings would be done on a project by project and in response to a complaint.

    1996-05-01

    High strain rate and high temperature response of three types of aluminum based particulate metal matrix ceramic composites is investigated by performing split Hopkinson pressure bar (SHPB) experiments. The composites are: NGP-2014 (15% SiC), NGT-6061 (15% SiC), and NGU-6061 (15% Al2O3), in which all the reinforcement materials are percentage by volume. Johnson-Cook constitutive model constants are evaluated from the high strain rate/high temperature data and implemented in a two dimensional finite element computer code (EPIC-2D) to simulate the penetration of an ogive nose tungsten projectile (23 grams) at a velocity 1.17 km/sec into the base 6061-T6 aluminum alloy and the composite NGU-6061. The simulated penetrations in the composite and in 6061-T6 aluminum agree with in 2%, in both materials, with the measured values.

  13. Peristaltic motion of Johnson-Segalman fluid in a curved channel with slip conditions.

    Directory of Open Access Journals (Sweden)

    Sadia Hina

    Full Text Available Slip effects on the peristaltic transport of Johnson-Segalman fluid through a curved channel have been addressed. The influence of wall properties is also analyzed. Long wavelength and low Reynolds number assumptions have been utilized in the mathematical formulation of the problem. The equations so formed have been solved numerically by shooting method through computational software Mathematica 8. In addition the analytic solution for small Weissenberg number (elastic parameter is computed through a regular perturbation method. An excellent agreement is noticed between the two solutions. The results indicate an increase in the magnitude of velocity with an intensification in the slip effect. Moreover the size and circulation of the trapped boluses increase with an increase in the slip parameter. Unlike the planar channel, the profiles of axial velocity are not symmetric about the central line of the channel.

    2016-07-12

    Phosphorus data were collected from the Kent Park Lake watershed in Johnson County, Iowa, in 2014 and 2015 to obtain information to assist in the management of the water quality in the lake. Phosphorus concentrations were measured for sediment from several ponds in the watershed and sediment deposited in the lake. The first set of samples was collected in 2014 to understand phosphorus in several potential sources to the lake and the spatial variability in lake sediments. Phosphorus concentrations ranged from 68 to 380 milligrams per kilogram in lake sediment and from 57 to 220 milligrams per kilogram in sedimentation and dredge spoil ponds. Additional samples were collected in 2015 to determine how phosphorus concentrations vary with depth in the lake sediment. Phosphorus concentrations generally decreased with increasing depth within the lake sediment. In 2015, total phosphorus concentrations in lake sediment ranged from 50 to 340 milligrams per kilogram.

    A 25-year-old Syrian male with a previous episode of Stevens-Johnson syndrome with bilateral corneal cicatrization previously underwent surgery for Type 1 Boston Keratoprosthesis (K-Pro). Sixteen months after the K-Pro surgery, the patient presented with decreased vision to hand motion and microbial keratitis of the graft around the K-Pro with purulent discharge. Corneal scrapings were nonrevealing. B-scan in 3 days showed increased debris in the vitreous cavity and thickened retinochoroidal layer. Intravitreal tap and injections of vancomycin and ceftazidime were performed. The vitreous culture revealed β-hemolytic Streptococcus agalactiae; fungal cultures were negative. Repeat B-scan 3 days later demonstrated decreased vitreous opacity, and the patient felt more comfortable and was without pain. His visual acuity improved to 20/70, ocular findings have been stable for 9 months, and the patient continues to be monitored. PMID:27994401

    is the known mapping class group invariant ideal cell decomposition of the Teichmueller space. This new 1-cocycle is mapping class group equivariant, so various contractions of its powers yield various combinatorial (co)cycles of the moduli space of curves, which are also new. Our combinatorial construction...... can be related to former works of Kawazumi and the first-named author with the consequence that the algebra generated by the cohomology classes represented by the new cocycles is precisely the tautological algebra of the moduli space. There is finally a discussion of prospects for similarly finding...... modulo N are derived for all N. Furthermore, the first Johnson homomorphism, which is defined from the classical Torelli group to the third exterior power of the homology of the surface, is shown to lift to an explicit canonical 1-cocycle of the Teichmueller space.

  18. Common front end systems for Space Shuttle and Space Station control centers at Johnson Space Center

    Science.gov (United States)

    Uljon, Linda; Muratore, John

    1993-03-01

    In the beginning of the fiscal year 1992, the development organizations of Johnson Space Center (JSC) were poised to begin two major projects: the Space Station Control Center and the refurbishment of the telemetry processing area of the Space Shuttle Mission Control Center. A study team established that a common front end concept could be used and could reduce development costs for both projects. A standard processor was defined to support most of the front end functions of both control centers and supports a consolidation of control positions which effectively reduces operations cost. This paper defines that common concept and describes the progress that has been made in development of the Consolidated Communications Facility (CCF) during the past year.

    2015-03-01

    Full Text Available Bronchiolitis obliterans (BO was defined as a nonreversible obstructive lung disease in which the bronchioles are always compressed and narrowed by fibrosis or inflammation. In the severe event of lung collapse after BO, surgical intervention is often recommended, and conservative therapy is thought to be ineffective. Here, we report the case of a 9-year old girl clinically diagnosed as having bronchiolitis obliterans with abrupt occlusion of the right B4b bronchus. After a lamotrigine-induced Stevens-Johnson syndrome (SJS occurred, she presented with total collapse of the right lung on admission, which was subsequently complicated by a pneumothorax during conservative treatment, but with the re-expansion of the right upper lobe after intervention. The case indicates the possibility of reversing pulmonary atelectasis in BO. Thus, surgery may not be necessary.

    Plasma behaviours are very complicated and the analyses are generally difficult. However, when the collisional processes play an important role in the plasma behaviour, the Monte Carlo method is often employed as a useful tool. For examples, in neutral particle injection heating (NBI heating), electron or ion cyclotron heating, and alpha heating, Coulomb collisions slow down high energetic particles and pitch angle scatter them. These processes are often studied by the Monte Carlo technique and good agreements can be obtained with the experimental results. Recently, Monte Carlo Method has been developed to study fast particle transports associated with heating and generating the radial electric field. Further it is applied to investigating the neoclassical transport in the plasma with steep gradients of density and temperatures which is beyong the conventional neoclassical theory. In this report, we briefly summarize the researches done by the present authors utilizing the Monte Carlo method. (author)

  7. Smart detectors for Monte Carlo radiative transfer

    CERN Document Server

    Baes, Maarten

    2008-01-01

    Many optimization techniques have been invented to reduce the noise that is inherent in Monte Carlo radiative transfer simulations. As the typical detectors used in Monte Carlo simulations do not take into account all the information contained in the impacting photon packages, there is still room to optimize this detection process and the corresponding estimate of the surface brightness distributions. We want to investigate how all the information contained in the distribution of impacting photon packages can be optimally used to decrease the noise in the surface brightness distributions and hence to increase the efficiency of Monte Carlo radiative transfer simulations. We demonstrate that the estimate of the surface brightness distribution in a Monte Carlo radiative transfer simulation is similar to the estimate of the density distribution in an SPH simulation. Based on this similarity, a recipe is constructed for smart detectors that take full advantage of the exact location of the impact of the photon pack...

    The purpose of the Diabetes Initiative of the Robert Wood Johnson Foundation is to demonstrate feasible and sustainable approaches to promoting diabetes self-management in primary care and community settings. The Diabetes Initiative of the Robert Wood Johnson Foundation includes 14 demonstration projects in primary care settings and in community-clinical partnerships. Projects serve predominantly indigent populations from varied cultural and linguistic backgrounds in urban, rural, and frontier settings around the United States. This report describes the Initiative, its ecological perspective on self-management, and implications for program development, sustainability, and dissemination. Ecological perspectives stress varied levels of influence ranging from individuals to communities and policies. Based on this, the Initiative has identified key resources and supports for self-management (individualized assessment, collaborative goal setting, enhancing skills, follow-up and support, community resources, and continuity of quality clinical care). Lessons learned include the central roles of community health workers, integration of healthy coping and attention to negative emotion and depression in self-management, community partnerships, approaches to ongoing follow-up and support, organizational factors in sustaining programs, and the utility of a collaborative learning network for program development. Sustainability stresses organizational and policy supports for the program. Dissemination of lessons learned will stress collaboration among interested parties, stimulating consumer understanding and demand for self-management services as central to diabetes care. The Diabetes Initiative demonstrates that effective self-management programs and supports can be implemented in real-world clinical and community settings, providing models of worthwhile, sustainable programs.

    Full Text Available RESUMEN: A partir de una reflexión inicial sobre el fenómeno de las conmemoraciones, el autor se plantea las causas por las que el tercer centenario de la muerte de Carlos II no dará lugar a ninguna conmemoración. Con independencia de las valoraciones de todo tipo que puedan hacerse de dichas celebraciones, lo cierto es que, en este caso, tal vez hubieran permitido acercar al gran público a uno de los monarcas peor conocidos y menos valorados de la historia de España. Lo más grave, sin embargo, es que la sombra del desconocimiento y el juicio peyorativo se extienden también sobre todo su reinado. Las investigaciones sobre aquel periodo, sin embargo, a pesar de que no abundan, muestran una realidad bastante distinta, en la que la decadencia y la pérdida de la hegemonía internacional convivieron con importantes iniciativas y realizaciones políticas, tanto en el ámbito interno de la Monarquía, como en las relaciones internacionales.ABSTRACT: Parting from an initial reflection about the phenomenon of commemorations, the author ponders the causes for which the third centenary of Charles IFs death will not be the subjet of any celebrations. Besides any evaluations which might be made of these events, the truth is that, perhaps, in this case, a commemoration would have brought the general public closer to one of the least known and worst valued monarchs in the history of Spain. What is more serious, however, is the fact that the shadow of ignorance and pejorative judgement extend also over the entirety of his reign. Though scarce, research about this period shows a very different reality, in wich decadence and the loss of international hegemony cohabitated with important political initiatives and achievements, both in the monarchy's internal domain and in the international arena.

  18. Error in Monte Carlo, quasi-error in Quasi-Monte Carlo

    CERN Document Server

    Kleiss, R H

    2006-01-01

    While the Quasi-Monte Carlo method of numerical integration achieves smaller integration error than standard Monte Carlo, its use in particle physics phenomenology has been hindered by the abscence of a reliable way to estimate that error. The standard Monte Carlo error estimator relies on the assumption that the points are generated independently of each other and, therefore, fails to account for the error improvement advertised by the Quasi-Monte Carlo method. We advocate the construction of an estimator of stochastic nature, based on the ensemble of pointsets with a particular discrepancy value. We investigate the consequences of this choice and give some first empirical results on the suggested estimators.

    Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN) are severe drug reactions associated with high mortality and multiple incapacitating sequelae. In the past 20 years, two large multinational case control studies, published in 1995 and 2008, had identified different degrees of drug associ

    2012-01-01

    A quantum Monte Carlo study of the atomization energies for the G2 set of molecules is presented. Basis size dependence of diffusion Monte Carlo atomization energies is studied with a single determinant Slater-Jastrow trial wavefunction formed from Hartree-Fock orbitals. With the largest basis set, the mean absolute deviation from experimental atomization energies for the G2 set is 3.0 kcal/mol. Optimizing the orbitals within variational Monte Carlo improves the agreement between diffusion Monte Carlo and experiment, reducing the mean absolute deviation to 2.1 kcal/mol. Moving beyond a single determinant Slater-Jastrow trial wavefunction, diffusion Monte Carlo with a small complete active space Slater-Jastrow trial wavefunction results in near chemical accuracy. In this case, the mean absolute deviation from experimental atomization energies is 1.2 kcal/mol. It is shown from calculations on systems containing phosphorus that the accuracy can be further improved by employing a larger active space.

    Full Text Available Las enfermedades de la piel muchas veces se asocian a medicamentos que pueden resultar en consecuencias fatales si no se detecta su causa a tiempo. El síndrome de Dress (Drug reaction with eosinophilia and systemic symptoms es una enfermedad caracterizada por la tríada rash, compromiso sistémico y visceral y en la mayoría de los casos se ha reportado la presencia de eosinofilia; que se asocia en la mayoría de las veces al uso de antiepilépticos aunque no de manera exclusiva. El síndrome de Stevens Johnson, es una reacción mucocutánea que se caracteriza por un rash macular en cara y tronco, con fiebre los primeros tres días y culmina con la presencia de bulas que son el resultado de un desacoplamiento de la epidermis y la dermis. Ambas enfermedades están asociadas a infecciones o al uso de medicamentos y mejoran con el diagnóstico oportuno y la suspensión inmediata del medicamento.In many situations, the skin pathologies are associated with the use of drugs in which the consequences can be mortal if it´s not diagnosed on time. The Dress Syndrome (Drug reaction with eosinophilia and systemic symptoms is an illness characterized by the presence of the triad which are rash, systemic symptoms, abdominal organ affectation and in many situations there were reports of the presence of eosinophilia; which are associated with the use of anticonvulsants but not exclusively. The Stevens Johnson syndrome is a mucous cutaneous reaction characterized by the presence of macular rash on the face and middle body, with fever in the first three days and ends up when the body shows the bullous dermal lesions due to the separation of the skin layers known as the epidermis and dermis. Both pathologies are associated with infections and the use of drugs, and the patients recovers with the quick recognition of the cause, by the physician, and the immediate suppression of the drug.

  10. Random Numbers and Monte Carlo Methods

    Science.gov (United States)

    Scherer, Philipp O. J.

    Many-body problems often involve the calculation of integrals of very high dimension which cannot be treated by standard methods. For the calculation of thermodynamic averages Monte Carlo methods are very useful which sample the integration volume at randomly chosen points. After summarizing some basic statistics, we discuss algorithms for the generation of pseudo-random numbers with given probability distribution which are essential for all Monte Carlo methods. We show how the efficiency of Monte Carlo integration can be improved by sampling preferentially the important configurations. Finally the famous Metropolis algorithm is applied to classical many-particle systems. Computer experiments visualize the central limit theorem and apply the Metropolis method to the traveling salesman problem.

    Full Text Available Sequential Monte Carlo methods are a very general class of Monte Carlo methodsfor sampling from sequences of distributions. Simple examples of these algorithms areused very widely in the tracking and signal processing literature. Recent developmentsillustrate that these techniques have much more general applicability, and can be appliedvery eectively to statistical inference problems. Unfortunately, these methods are oftenperceived as being computationally expensive and dicult to implement. This articleseeks to address both of these problems.A C++ template class library for the ecient and convenient implementation of verygeneral Sequential Monte Carlo algorithms is presented. Two example applications areprovided: a simple particle lter for illustrative purposes and a state-of-the-art algorithmfor rare event estimation.

    Energy Technology Data Exchange (ETDEWEB)

    Ormand, W.E.

    1995-03-01

    The formalism for the auxiliary-field Monte Carlo approach to the nuclear shell model is presented. The method is based on a linearization of the two-body part of the Hamiltonian in an imaginary-time propagator using the Hubbard-Stratonovich transformation. The foundation of the method, as applied to the nuclear many-body problem, is discussed. Topics presented in detail include: (1) the density-density formulation of the method, (2) computation of the overlaps, (3) the sign of the Monte Carlo weight function, (4) techniques for performing Monte Carlo sampling, and (5) the reconstruction of response functions from an imaginary-time auto-correlation function using MaxEnt techniques. Results obtained using schematic interactions, which have no sign problem, are presented to demonstrate the feasibility of the method, while an extrapolation method for realistic Hamiltonians is presented. In addition, applications at finite temperature are outlined.

    We investigate the inclusion of variable spins in electronic structure quantum Monte Carlo, with a focus on diffusion Monte Carlo with Hamiltonians that include spin-orbit interactions. Following our previous introduction of fixed-phase spin-orbit diffusion Monte Carlo, we thoroughly discuss the details of the method and elaborate upon its technicalities. We present a proof for an upper-bound property for complex nonlocal operators, which allows for the implementation of T-moves to ensure the variational property. We discuss the time step biases associated with our particular choice of spin representation. Applications of the method are also presented for atomic and molecular systems. We calculate the binding energies and geometry of the PbH and Sn2 molecules, as well as the electron affinities of the 6p row elements in close agreement with experiments.

    Simulation affects our life every day through our interactions with the automobile, airline and entertainment industries, just to name a few. The use of simulation in drug development is relatively new, but its use is increasing in relation to the speed at which modern computers run. One well known example of simulation in drug development is molecular modelling. Another use of simulation that is being seen recently in drug development is Monte Carlo simulation of clinical trials. Monte Carlo simulation differs from traditional simulation in that the model parameters are treated as stochastic or random variables, rather than as fixed values. The purpose of this paper is to provide a brief introduction to Monte Carlo simulation methods.

    2011-01-01

    We present the public release of the Bayesian sampling algorithm for cosmology, CosmoPMC (Cosmology Population Monte Carlo). CosmoPMC explores the parameter space of various cosmological probes, and also provides a robust estimate of the Bayesian evidence. CosmoPMC is based on an adaptive importance sampling method called Population Monte Carlo (PMC). Various cosmology likelihood modules are implemented, and new modules can be added easily. The importance-sampling algorithm is written in C, and fully parallelised using the Message Passing Interface (MPI). Due to very little overhead, the wall-clock time required for sampling scales approximately with the number of CPUs. The CosmoPMC package contains post-processing and plotting programs, and in addition a Monte-Carlo Markov chain (MCMC) algorithm. The sampling engine is implemented in the library pmclib, and can be used independently. The software is available for download at http://www.cosmopmc.info.

  17. Quantum speedup of Monte Carlo methods.

    Montanaro, Ashley

    2015-09-08

    Monte Carlo methods use random sampling to estimate numerical quantities which are hard to compute deterministically. One important example is the use in statistical physics of rapidly mixing Markov chains to approximately compute partition functions. In this work, we describe a quantum algorithm which can accelerate Monte Carlo methods in a very general setting. The algorithm estimates the expected output value of an arbitrary randomized or quantum subroutine with bounded variance, achieving a near-quadratic speedup over the best possible classical algorithm. Combining the algorithm with the use of quantum walks gives a quantum speedup of the fastest known classical algorithms with rigorous performance bounds for computing partition functions, which use multiple-stage Markov chain Monte Carlo techniques. The quantum algorithm can also be used to estimate the total variation distance between probability distributions efficiently.

    2016-10-01

    Most experimental and theoretical studies of adiabatic optimization use stoquastic Hamiltonians, whose ground states are expressible using only real nonnegative amplitudes. This raises a question as to whether classical Monte Carlo methods can simulate stoquastic adiabatic algorithms with polynomial overhead. Here we analyze diffusion Monte Carlo algorithms. We argue that, based on differences between L1 and L2 normalized states, these algorithms suffer from certain obstructions preventing them from efficiently simulating stoquastic adiabatic evolution in generality. In practice however, we obtain good performance by introducing a method that we call Substochastic Monte Carlo. In fact, our simulations are good classical optimization algorithms in their own right, competitive with the best previously known heuristic solvers for MAX-k -SAT at k =2 ,3 ,4 .

    2017-01-01

    Monte Carlo simulation is an unbiased numerical tool for studying classical and quantum many-body systems. One of its bottlenecks is the lack of a general and efficient update algorithm for large size systems close to the phase transition, for which local updates perform badly. In this Rapid Communication, we propose a general-purpose Monte Carlo method, dubbed self-learning Monte Carlo (SLMC), in which an efficient update algorithm is first learned from the training data generated in trial simulations and then used to speed up the actual simulation. We demonstrate the efficiency of SLMC in a spin model at the phase transition point, achieving a 10-20 times speedup.

    Full Text Available An 18-year-old woman was referred with late sequelae of chloroquine-induced Steven-Johnson syndrome. At the time of presentation, the symblepharon was involving the upper lids to almost the whole of the cornea, and part of the lower bulbar conjunctiva with the lower lid bilaterally. Other ocular examinations were not possible due to the symblepharon. B-scan ultrasonography revealed acoustically clear vitreous, normal chorioretinal thickness, and normal optic nerve head, with an attached retina. Conjunctivo-corneal adhesion released by superficial lamellar dissection of the cornea. Ocular surface reconstruction was carried out with a buccal mucous membrane. A bandage contact lens was placed over the cornea followed by the symblepharon ring to prevent further adhesion. The mucosal graft was well taken up along with corneal re-epithelization. Best corrected visual acuity of 20/120 in both sides after 1 month and 20/80 after 3 months was achieved and maintained till the 2.5-year follow-up.

    As NASA moves beyond exploring low earth orbit and into deep space exploration, increased communication delays between astronauts and earth drive a need for crew to become more autonomous (earth-independent). Currently crew on board the International Space Station (ISS) have limited insight into specific vehicle system performance because of the dependency on monitoring and real-time communication with Mission Control. Wearable technology provides a method to bridge the gap between the human (astronaut) and the system (spacecraft) by providing mutual monitoring between the two. For example, vehicle or environmental information can be delivered to astronauts through on-body devices and in return wearables provide data to the spacecraft regarding crew health, location, etc. The Wearable Electronics and Applications Research (WEAR) Lab at the NASA Johnson Space Center utilizes a collaborative approach between engineering and human factors to investigate the use of wearables for spaceflight. Zero and partial gravity environments present unique challenges to wearables that require collaborative, user-centered, and iterative approaches to the problems. Examples of the WEAR Lab's recent wearable projects for spaceflight will be discussed.

    Full Text Available Stevens-Johnson syndrome (SJS and toxic epidermal necrolysis (TEN are life-threatening adverse reactions, which could be induced by a variety of drugs. It was proposed that human leukocyte antigen (HLA-restricted presentation of antigens (drugs or their metabolites to T lymphocytes initiates the immune reactions of SJS/ TEN. However, the genetic susceptibility and the exact pathogenesis were not clear until the recent studies. We first identified that HLA-B*1502 is strongly associated with carbamazepine (CBZ-induced SJS/TEN and HLA-B*5801 with allopurinol-SJS/TEN in Han Chinese. The same associations had been validated across different human populations. For the downstream danger signals, Fas-Fas ligand (FasL and perforin/granzyme B had been advocated as cytotoxic mediators for keratinocyte death in SJS/TEN. However, expression levels of these cytotoxic proteins from the skin lesions were too low to explain the distinct and extensive epidermal necrosis. Our recent study identified that the granulysin, a cytotoxic protein released from cytotoxic T cells or natural killer (NK cells, is a key mediator for disseminated keratinocyte death in SJS/TEN. This article aims to provide an overview of both of the genomic and immunologic perspectives of SJS/TEN. These studies give us a better understanding of the immune mechanisms, biomarkers for disease prevention and early diagnosis, as well as providing the therapeutic targets for the treatments of SJS/TEN.

    The unit of thermodynamic temperature, the kelvin, will be redefined in 2018 by fixing the value of the Boltzmann constant, k. The present CODATA recommended value of k is determined predominantly by acoustic gas-thermometry results. To provide a value of k based on different physical principles, purely electronic measurements of k were performed by using a Johnson noise thermometer to compare the thermal noise power of a 200 Ohm sensing resistor immersed in a triple-point-of-water cell to the noise power of a quantum-accurate pseudo-random noise waveform of nominally equal noise power. Measurements integrated over a bandwidth of 550 kHz and a total integration time of 33 days gave a measured value of k = 1.3806514(48)x10^-23 J/K, for which the relative standard uncertainty is 3.5x10^-6 and the relative offset from the CODATA 2010 value is +1.9x10^-6.

    1994-01-01

    This paper presents an overview of the proposed Lyndon B. Johnson Space Center (JSC) precompetitive, dual-use technology investment project in robotics. New robotic technology in advanced robots, which can recognize and respond to their environments and to spoken human supervision so as to perform a variety of combined mobility and manipulation tasks in various sectors, is an obejective of this work. In the U.S. economy, such robots offer the benefits of improved global competitiveness in a critical industrial sector; improved productivity by the end users of these robots; a growing robotics industry that produces jobs and profits; lower cost health care delivery with quality improvements; and, as these 'intelligent' robots become acceptable throughout society, an increase in the standard of living for everyone. In space, such robots will provide improved safety, reliability, and productivity as Space Station evolves, and will enable human space exploration (by human/robot teams). The proposed effort consists of partnerships between manufacturers, universities, and JSC to develop working production prototypes of these robots by leveraging current development by both sides. Currently targeted applications are in the manufacturing, health care, services, and construction sectors of the U.S. economy and in the inspection, servicing, maintenance, and repair aspects of space exploration. But the focus is on the generic software architecture and standardized interfaces for custom modules tailored for the various applications allowing end users to customize a robot as PC users customize PC's. Production prototypes would be completed in 5 years under this proposal.

    The American Burn Association recommends that patients with toxic epidermal necrolysis-Stevens Johnson syndrome (TEN-SJS) or burn inhalation injuries would benefit from admission or transfer to a burn center (BC). This study examines to what extent those criteria are observed within a regional burn network. Hospital discharge data from 2000 to 2010 was obtained for all hospitals within the South Florida regional burn network. Patients with International Classification of Disease-9th revision discharge diagnoses for TEN-SJS or burn inhalation injury and their triage destination were compared using burn triage referral criteria to determine whether the patients were triaged differently from American Burn Association recommendations. Two hundred ninety-nine TEN-SJS and 131 inhalation injuries were admitted to all South Florida hospitals. Only 25 (8.4%) of TEN-SJS and 27 (21%) of inhalation injuries were admitted to the BC. BC patients had greater length of stay (TEN-SJS 22 vs 10 days; inhalation 13 vs 7) and were more likely to be funded by charity or be self-paid (TEN-SJS 24 vs 9.5%, P = .025; inhalation 44 vs 14%, P burn network. Unfamiliarity with triage criteria, patient insurance status, and overcoding may play a role. Further studies should fully characterize the problem and implement education or incentives to encourage more appropriate triage.

    The Johnson Creek landslide is a translational, primarily bedrock landslide located along the Oregon coast about 5 km north of Newport. The landslide has damaged U.S. Highway 101 many times since construction of the highway and at least two geological and geotechnical investigations of the landslide have been performed by Oregon State agencies. In cooperation with the Oregon Department of Geology and Mineral Industries and the Oregon Department of Transportation, the U.S. Geological Survey upgraded landslide monitoring systems and installed additional monitoring devices at the landslide beginning in 2004. Monitoring devices at the landslide measured landslide displacement, rainfall, air temperature, shallow soil-water content, and ground-water temperature and pressure. The devices were connected to automatic dataloggers and read at one-hour and, more recently, 15-minute intervals. Monitoring results were periodically downloaded from the dataloggers using cellular telemetry. The purposes of this report are to describe and present preliminary monitoring data from November 19, 2004, to March 31, 2007.

    Ultrastructure of Kupffer cells and hepatocytes in liver bioptate was evaluated in a 17-year-old boy with Dubin -Johnson syndrome (DJS). The liver tissue obtained by needle biopsy was fixed in glutaraldehyde and paraformaldehyde and routinely processed for electron microscopic analysis. The ultrastructural examinations of liver bioptate revealed the accumulation of membranebound, electron-dense lysosomal granules within the cytoplasm of hepatocytes, characteristic of DJS. They were located mainly in the vicinity of the biliary pole, and preferentially in the centrilobular region that corresponded to the pigment deposits seen under light microscope. The presence of the granules was accompanied by dilated elements of the granular endoplasmic reticulum and paracrystalline mitochondrial inclusions as well as dilation of the bile canaliculi. The changes in hepatocytes coexisted with marked stimulation and enhanced phagocytic activity of Kupffer cells. This was manifested in the accumulation of pigment deposits within their cytoplasm that corresponded to those observed in hepatocytes.Hyperactive pericentral Kupffer cells which are involved in the response to pigmentary material originating from disintegrated hepatocytes may play an essential role in the development of DJS.

    Dubin-Johnson syndrome (DJS) is a rare autosomal recessive inheritance disorder of bilirubin metabolism. Herein we reported a complicated but interesting case which is readily resulted in misdiagnosis or an indefinite diagnosis, and this is the first reported familial case of DJS with multiple liver cavernous hemangiomas. A 49-year-old man was referred to our hospital for jaundice and multiple low-density liver masses. Extensive laboratory investigations showed conjugated hyperbilirubinaemia and positive urine bilirubin. Microscopically, lesions were composed of blood-filled vascular channels of various sizes lined by a single layer of flat endothelial cells supported by fibrous tissue. Coarse brown granules presented in the hepatocytes of the liver lobules locating beside the tumor, particularly in the centrilobular hepatocytes, and the granules showed blue-green with Schmorl's reaction lipofuscin staining. Interestingly, one of the patient's six siblings (female) shared the same condition with him. The relationship between DJS and hemangiomas remains unclear, and it might be contributed to some hereditary factors, or probably occurred simultaneously by chance. It was certified that the true reason for the long-term unclear jaundice was DJS, which was presumed clinically to be caused by bile excretion obstacles associated with the hemangiomas. Liver biopsy and histochemical stain may be helpful to identify the reason of jaundice and avoid misdiagnosis or an indefinite diagnosis.

    A 77-year-old male patient with history of jaundice was referred to our hospital for treatment of hepatocellular carcinoma (HCC). He was found to have Dubin-Johnson syndrome (DJS), a clinical feature of constitutional jaundice with conjugated hyperbilirubinemia, and indocyanine green (ICG) excretory defect, both of which are rare conditions. Total bilirubin was 5.1 mg/dl and ICG retention at 15 min (ICGR15) (77.1 %). Converted ICGR15 from GSA scintigraphy was 15.9 %. Resection of the medial segment and ventral region of the anterior segment of the liver as well as cholecystectomy were performed. The background of the liver tissue was blackish yellow and consistent with DJS and chronic hepatitis. Although total bilirubin level increased to 8.2 mg/dl on the 2nd postoperative day, the patient ultimately recovered and he was discharged on the 14th day. His 1- and 2-year medical checkups indicated recurrence of HCC. He underwent transarterial chemoembolization and is presently doing well 39 months after surgery. We report here on evaluation and treatment of patients with such disorders.

    1990-01-01

    The Management Information and Decision Support Environment (MIDSE) is a research activity to build and test a prototype of a generic human interface on the Johnson Space Center (JSC) Information Network (CIN). The existing interfaces were developed specifically to support operations rather than the type of data which management could use. The diversity of the many interfaces and their relative difficulty discouraged occasional users from attempting to use them for their purposes. The MIDSE activity approached this problem by designing and building an interface to one JSC data base - the personnel statistics tables of the NASA Personnel and Payroll System (NPPS). The interface was designed against the following requirements: generic (use with any relational NOMAD data base); easy to learn (intuitive operations for new users); easy to use (efficient operations for experienced users); self-documenting (help facility which informs users about the data base structure as well as the operation of the interface); and low maintenance (easy configuration to new applications). A prototype interface entitled the JSC Management Information Systems (JSCMIS) was produced. It resides on CIN/PROFS and is available to JSC management who request it. The interface has passed management review and is ready for early use. Three kinds of data are now available: personnel statistics, personnel register, and plan/actual cost.

    2014-01-01

    The sensitivity of a THz hot-electron nanobolometer (nano-HEB) made from a normal metal is analyzed. Johnson Noise Thermometry (JNT) is employed as a readout technique. In contrast to its superconducting TES counterpart, the normal-metal nano-HEB can operate at any cryogenic temperature depending on the required radiation background limited Noise Equivalent Power (NEP). It does not require bias lines; 100s of nano-HEBs can be read by a single low-noise X-band amplifier via a filter bank channelizer. The modeling predicts that even with the sensitivity penalty due to the amplifier noise, an NEP ~ 10$^{-20}$ - 10$^{-19}$ W/Hz$^{1/2}$ can be expected at 50-100 mK in 10-20 nm thin titanium (Ti) normal metal HEBs with niobium (Nb) contacts. This NEP is fairly constant over a range of readout frequencies ~ 10 GHz. Although materials with weaker electron-phonon coupling (bismuth, graphene) do not improve the minimum achievable NEP, they can be considered if a larger than 10 GHz readout bandwidth is required.

    2013-05-01

    Full Text Available The style of Samuel Johnson’s essays for the periodicals The Rambler, The Adventurer and The Idler is quite different from that of earlier eighteenth–century essayists such as Joseph Addison and Jonathan Swift. However, despite advances in recent years in corpus–based stylistic approaches to texts, a comparison of these three authors using current corpus–analytic techniques has yet to be attempted. This paper reports on the first stages of such a project. Johnson’s essays are compared with Addison and Swift’s essays using WordSmith Tools 5, and an analysis of keywords, semantic groupings of keywords, and key collocations of keywords in Johnson’s essays are identified. It is argued that a keyword analysis brings to the fore grammatical aspects of Johnsonian sentence patterns and provides empirical support for what have hitherto been only intuitively–based statements regarding his style. Also, further patterns in the data will be identified through a phraseological analysis of the essays focusing on the most common four–word clusters (4–grams that Johnson uses.

    A 46-year-old man developed Stevens-Johnson syndrome and toxic epidermal necrolysis overlap, with severe localized denudation of the skin on the head and neck, following radiotherapy and oral temozolomide therapy for cranial glioblastoma multiforme. He also had a primary malignant fibrous histiocytoma of the thigh that was amputated 5 years earlier. A rash developed after 7 days of radio- and chemotherapy. It was an extensive maculopapular rash that started over the temporal area of the head and rapidly spread, sparing only the distal limbs. Radiotherapy and temozolomide were stopped on the tenth day but the rash rapidly progressed for the next 4-6 days. Following this, the spread halted and complete recovery was observed within the next 2 weeks. The peculiarity of the presentation in this case was that the brunt of the disease with severe skin denudation was localized to the surrounding areas of cranial radiotherapy. The patient was also receiving oral phenytoin, diclofenac, and parenteral dexamethasone before chemotherapy was started. These medications were continued, even after development of the skin rash, until well after full recovery from the skin lesions. After critical evaluation of disease onset, progression, and recovery, and their relationship to the introduction and withdrawal of different medicines, it appeared that either temozolomide alone or in combination with radiotherapy most probably triggered the condition.

    Uranium minerals were discovered in the Pumpkin Buttes area, Campbell and Johnson Counties, Wyo., by the U. S. Geological Survey in October 1951. From June to November 1952, an area of about 750 square miles was examined for uranium deposits, and 211 localities having abnormally high radioactivity were found; uranium minerals are visible at 121 of these localities. All known uranium mineralization in the area is restricted to sandstones of the Wasatch formation, except sparsely disseminated uranium in the sandstone of the White River formation, which caps the Pumpkin Buttes, mid several localities on the Great Pine Ridge southwest of the Pumpkin Buttes where iron-saturated sandstone and clinker in the Fort Union formation have above-normal radioactivity. The uranium occurrences in the Wasatch formation are in a red sandstone zone 450 to 900 feet above the base of the formation and are of two types: small concretionary masses of uranium, iron, manganese and vanadium minerals in sandstone, and irregular zones in which uranium minerals are disseminated in sandstone. The second type is usually larger but of lower grade than the first. Most of the localities at which uranium occurs are in a north-trending belt about 60 miles long and 18 miles in maximum width.

  17. Stevens-Johnson syndrome / toxic epidermal necrolysis: an Asia-Pacific perspective.

    2013-10-01

    Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are severe cutaneous adverse reactions (SCAR) to drugs which are associated with significant morbidity and mortality. High risk drugs in Asia are similar to those reported worldwide. Human leukocyte antigen (HLA)-related risk alleles for carbamazepine and allopurinol SCAR are unique to Asians. Although prognostic scoring systems like the SCORTEN have been used for more than a decade, pitfalls and caveats need to be recognized, in particular in patients with multiple medical co-morbidities and systemic features in SJS/TEN. In centres without a tertiary Burns Centre, SJS/TEN patients can still be managed successfully in general and dermatology wards with well-executed supportive/nursing care. Controversy remains regarding the effectiveness of immunomodulation in reducing SJS/TEN morbidity, mortality and hastening re-epithelialization. Despite paucity of robust evidence, intravenous immunoglobulins and ciclosporin remain the most commonly used modalities worldwide. Acute and long-term ocular effects are an important source of morbidity for which emerging ophthalmic therapies appear promising. Quality of life issues have now become an important outcome in patients with SJS/TEN as they often impact survivors' future attitudes towards pharmacotherapy. Even though pharmacogenetic testing for high-risk drugs appears to be the panacea for preventing carbamazepine- and allopurinol-induced SJS/TEN in ethnic Asians, many issues remain before health regulators in our region can conclusively determine whether testing should be made mandatory or highly recommended as standard of care.

    This study investigated the Taylor coal bed in Johnson and Martin counties, eastern Kentucky, using field and petrographic techniques to develop a depositional model of the coal bed. Petrography and chemistry of the coal bed were examined. Multiple benches of the Taylor coal bed were correlated over a 10 km distance. Three sites were studied in detail. The coal at the western and eastern sites were relatively thin and split by thick clastic partings. The coal at the central site was the thickest and unsplit. Two major clastic partings are included in the coal bed. Each represents a separate and distinct fluvial splay. The Taylor is interpreted to have developed on a coastal plain with periodic flooding from nearby, structurally-controlled fluvial systems. Doming is unlikely due to the petrographic and chemical trends, which are inconsistent with modern Indonesian models. The depositional history and structural and stratigraphic setting suggest contemporaneous structural influence on thickness and quality of the Taylor coal bed in this area.

    Full Text Available Case summary A 5-year-old, spayed female, indoor-only domestic shorthair cat was referred with an acute history of multifocal cutaneous and mucocutaneous erosive-ulcerative lesions and skin detachment. The lesions occurred on the seventh day of therapy with cefadroxil. Erosive-ulcerative and occasionally crusted lesions were apparent on the medial and lateral canthus of both eyes, ventral neck, abdomen, perivulvar region, periungual skin and medial aspect of the front and hindlimbs. Diffuse and severe exfoliation was present on the dorsum and tail base and in both external ear canals. The cat was also dehydrated, tachycardic and febrile. Histopathological examination revealed extensive epidermal ulceration, interface dermatitis with vacuolar degeneration, apoptosis at multiple epidermal levels and basal, suprabasal and spinous dermoepidermal detachment. The histopathological diagnosis was consistent with Stevens–Johnson syndrome/toxic epidermal necrolysis (SJS/TEN. The recently reported Algorithm of Drug Causality in Epidermal Necrolysis (ALDEN, currently used in human medicine, was applied and a score of +6 was calculated; this supported the view that SJS/TEN in this cat was very likely to be associated with cefadroxil administration. Relevance and novel information This clinical communication reports cefadroxil as a very probable cause of SJS/TEN in a cat; the ALDEN was applied in this case and supported diagnosis.

    2006-02-14

    Ultrastructure of Kupffer cells and hepatocytes in liver bioptate was evaluated in a 17-year-old boy with Dubin-Johnson syndrome (DJS). The liver tissue obtained by needle biopsy was fixed in glutaraldehyde and paraformaldehyde and routinely processed for electron microscopic analysis. The ultrastructural examinations of liver bioptate revealed the accumulation of membrane-bound, electron-dense lysosomal granules within the cytoplasm of hepatocytes, characteristic of DJS. They were located mainly in the vicinity of the biliary pole, and preferentially in the centrilobular region that corresponded to the pigment deposits seen under light microscope. The presence of the granules was accompanied by dilated elements of the granular endoplasmic reticulum and paracrystalline mitochondrial inclusions as well as dilation of the bile canaliculi. The changes in hepatocytes co-existed with marked stimulation and enhanced phagocytic activity of Kupffer cells. This was manifested in the accumulation of pigment deposits within their cytoplasm that corresponded to those observed in hepatocytes. Hyperactive pericentral Kupffer cells which are involved in the response to pigmentary material originating from disintegrated hepatocytes may play an essential role in the development of DJS.

    Future robotic and human spaceflight missions to the Moon, Mars, asteroids, and comets will require curating astromaterial samples with minimal inorganic and organic contamination to preserve the scientific integrity of each sample. 21st century sample return missions will focus on strict protocols for reducing organic contamination that have not been seen since the Apollo manned lunar landing program. To properly curate these materials, the Astromaterials Acquisition and Curation Office under the Astromaterial Research and Exploration Science Directorate at NASA Johnson Space Center houses and protects all extraterrestrial materials brought back to Earth that are controlled by the United States government. During fiscal year 2012, we conducted a year-long project to compile historical documentation and laboratory tests involving organic investigations at these facilities. In addition, we developed a plan to determine the current state of organic cleanliness in curation laboratories housing astromaterials. This was accomplished by focusing on current procedures and protocols for cleaning, sample handling, and storage. While the intention of this report is to give a comprehensive overview of the current state of organic cleanliness in JSC curation laboratories, it also provides a baseline for determining whether our cleaning procedures and sample handling protocols need to be adapted and/or augmented to meet the new requirements for future human spaceflight and robotic sample return missions.

    The United State's big space projects of the next decades, such as Space Station and the Human Exploration Initiative, will need the development of many millions of lines of mission critical software. NASA-Johnson (JSC) is identifying and developing some of the Computer Aided Software Engineering (CASE) technology that NASA will need to build these future software systems. The goal is to improve the quality and the productivity of large software development projects. New trends are outlined in CASE technology and how the Software Technology Branch (STB) at JSC is endeavoring to provide some of these CASE solutions for NASA is described. Key software technology components include knowledge-based systems, software reusability, user interface technology, reengineering environments, management systems for the software development process, software cost models, repository technology, and open, integrated CASE environment frameworks. The paper presents the status and long-term expectations for CASE products. The STB's Reengineering Application Project (REAP), Advanced Software Development Workstation (ASDW) project, and software development cost model (COSTMODL) project are then discussed. Some of the general difficulties of technology transfer are introduced, and a process developed by STB for CASE technology insertion is described.

    2016-01-01

    Full Text Available We report first-principles calculations, within density functional theory, on the lead halide compounds PbCl2, PbBr2, and CH3NH3PbBr3−xClx, taking into account spin-orbit coupling. We show that, when the modified Becke-Johnson exchange potential is used with a suitable choice of defining parameters, excellent agreement between calculations and experiment is obtained. The computational model is then used to study the effect of replacing the methylammonium cation in CH3NH3PbI3 and CH3NH3PbBr3 with either N2H5+or N2H3+, which have slightly smaller ionic radii than methylammonium. We predict that a considerable downshift in the values of the band gaps occurs with this replacement. The resulting compounds would extend optical absorption down to the near-infrared region, creating excellent light harvesters for solar cells.

    2005-01-01

    Full Text Available Dubin-Johnson syndrome (DJS is caused by a deficiency of the human canalicular multispecific organic anion transporter (cMOAT. A new lipophilic copper-64 complex of 1,4,7-tris(carboxymethyl-10-(tetradecyl-1,4,7,10-tetraazadodecane (5 was prepared and evaluated for potential as a diagnostic tool for DJS. The prepared ligand was labeled with 64Cu citrate in high radiochemical purity. In vivo uptake and clearance of the complex was determined through biodistribution studies using normal Sprague-Dawley rats and mutant cMOAT-deficient (TR− rats. In normal rats, the radioactive copper complex was cleared quickly from the body exclusively through the hepatic pathway. The 64Cu complex was taken up rapidly by the liver and quickly excreted into the small intestine and then the upper large intestine, whereas < 1% ID/organ was found in the kidney at all time points post injection. Whereas activity was accumulated continuously in the liver of TR− rats, it was not excreted into the small intestine. MicroPET studies of normal and TR rats were consistent with biodistribution data and showed dramatically different images. This study strongly suggests that cMOAT is involved in excretion of 64Cu-5. The significant difference between the biodistribution data and microPET images of the normal and TR− rats demonstrates that this new 64Cu complex may allow noninvasive diagnosis of DJS in humans.

    The NASA Johnson Space Center (JSC) in Houston, Texas has a Sustainability Partnership team that seeks ways for earth-based sustainability practices to also benefit space exploration research. A renewable energy gathering system was installed in 2007 at the JSC Child Care Center (CCC) which also offers a potential test bed for space exploration power generation and remote monitoring and control concepts. The system comprises: 1) several different types of photovoltaic panels (29 kW), 2) two wind-turbines (3.6 kW total), and 3) one roof-mounted solar thermal water heater and tank. A tie to the JSC local electrical grid was provided to accommodate excess power. The total first year electrical energy production was 53 megawatt-hours. A web-based real-time metering system collects and reports system performance and weather data. Improvements in areas of the CCC that were detected during subsequent energy analyses and some concepts for future efforts are also presented.

    With strict detailed balance, parallel Monte Carlo simulation through domain decomposition cannot be validated with conventional Markov chain theory, which describes an intrinsically serial stochastic process. In this work, the parallel version of Markov chain theory and its role in accelerating Monte Carlo simulations via cluster computing is explored. It is shown that sequential updating is the key to improving efficiency in parallel simulations through domain decomposition. A parallel scheme is proposed to reduce interprocessor communication or synchronization, which slows down parallel simulation with increasing number of processors. Parallel simulation results for the two-dimensional lattice gas model show substantial reduction of simulation time for systems of moderate and large size.

    The precision of Radiosurgery Treatment planning systems is limited by the approximations of their algorithms and by their dosimetrical input data. This fact is especially important in small fields. However, the Monte Carlo methods is an accurate alternative as it considers every aspect of particle transport. In this work an acoustic neurinoma is studied by comparing the dose distribution of both a planning system and Monte Carlo. Relative shifts have been measured and furthermore, Dose-Volume Histograms have been calculated for target and adjacent organs at risk. (orig.)

    Monte Carlo simulations are a valuable tool to model the generation, separation, and collection of charges in organic photovoltaics where charges move by hopping in a complex nanostructure and Coulomb interactions between charge carriers are important. We review the Monte Carlo techniques that have been applied to this problem, and describe the results of simulations of the various recombination processes that limit device performance. We show how these processes are influenced by the local physical and energetic structure of the material, providing information that is useful for design of efficient photovoltaic systems.

    A library of Monte Carlo subroutines has been developed for the purpose of design of neutron scattering instruments. Using small-angle scattering as an example, the philosophy and structure of the library are described and the programs are used to compare instruments at continuous wave (CW) and long-pulse spallation source (LPSS) neutron facilities. The Monte Carlo results give a count-rate gain of a factor between 2 and 4 using time-of-flight analysis. This is comparable to scaling arguments based on the ratio of wavelength bandwidth to resolution width.

The Rational Hybrid Monte Carlo (RHMC) algorithm, where Hybrid Monte Carlo is performed using a rational approximation in place the usual inverse quark matrix kernel is one of these developments. This algorithm has been found to be extremely beneficial in many areas of lattice QCD (chiral fermions, finite temperature, Wilson fermions etc.). We review the algorithm and some of these benefits, and we compare against other recent algorithm developements. We conclude with an update of the Berlin wall plot comparing costs of all popular fermion formulations.

    The Nez Perce Tribe Johnson Creek Artificial Propagation Enhancement Project (JCAPE) has conducted juvenile and adult monitoring and evaluation studies for its 10th consecutive year. Completion of adult and juvenile Chinook salmon studies were conducted for the purpose of evaluating a small-scale production initiative designed to increase the survival of a weak but recoverable spawning aggregate of summer Chinook salmon Oncorhynchus tshawytscha. The JCAPE program evaluates the life cycle of natural origin (NOR) and hatchery origin (HOR) supplementation fish to quantify the key performance measures: abundance, survival-productivity, distribution, genetics, life history, habitat, and in-hatchery metrics. Operation of a picket style weir and intensive multiple spawning ground surveys were completed to monitor adult Chinook salmon and a rotary screw trap was used to monitor migrating juvenile Chinook salmon in Johnson Creek. In 2007, spawning ground surveys were conducted on all available spawning habitat in Johnson Creek and one of its tributaries. A total of 63 redds were observed in the index reach and 11 redds for all other reaches for a combined count of 74 redds. Utilization of carcass recovery surveys and adult captures at an adult picket weir yielded a total estimated adult escapement to Johnson Creek of 438 Chinook salmon. Upon deducting fish removed for broodstock (n=52), weir mortality/ known strays (n=12), and prespawning mortality (n=15), an estimated 359 summer Chinook salmon were available to spawn. Estimated total migration of brood year 2005 NOR juvenile Chinook salmon at the rotary screw trap was calculated for three seasons (summer, fall, and spring). The total estimated migration was 34,194 fish; 26,671 of the NOR migrants left in the summer (July 1 to August 31, 2005) as fry/parr, 5,852 left in the fall (September 1 to November 21, 2005) as presmolt, and only 1,671 NOR fish left in the spring (March 1 to June 30, 2006) as smolt.

    The Monte Carlo method has become a fundamental tool for brachytherapy dosimetry mainly because no difficulties associated with experimental dosimetry. In brachytherapy the main handicap of experimental dosimetry is the high dose gradient near the present sources making small uncertainties in the positioning of the detectors lead to large uncertainties in the dose. This presentation will review mainly the procedure for calculating dose distributions around a fountain using the Monte Carlo method showing the difficulties inherent in these calculations. In addition we will briefly review other applications of the method of Monte Carlo in brachytherapy dosimetry, as its use in advanced calculation algorithms, calculating barriers or obtaining dose applicators around.

    KAUST Repository

    Liang, Faming

    2009-03-01

    The stochastic approximation Monte Carlo (SAMC) algorithm has recently been proposed as a dynamic optimization algorithm in the literature. In this paper, we show in theory that the samples generated by SAMC can be used for Monte Carlo integration via a dynamically weighted estimator by calling some results from the literature of nonhomogeneous Markov chains. Our numerical results indicate that SAMC can yield significant savings over conventional Monte Carlo algorithms, such as the Metropolis-Hastings algorithm, for the problems for which the energy landscape is rugged. © 2008 Elsevier B.V.

    Stevens-Johnson syndrome and toxic epidermal necrolysis are severe, life-threatening drug reactions involving skin and membranes mucous, which are associated with significant morbidity and mortality and triggered, especially by drug exposure. Different studies have demonstrated that drug response is a multifactorial character and that the interindividual variability in this response depends on both environmental and genetic factors. The last ones have a relevant significance. In fact, the identification of new specific genetic markers involved in the response to drugs, will be of great utility to establish a more personalized therapeutic approach and to prevent the appearance of these adverse reactions. In this review, we summarize recent progresses in the Pharmacogenetics studies related to Stevens-Johnson syndrome/toxic epidermal necrolysis reporting the major genetic factors identified in the last years as associated with the disease and highlighting the use of some of these genomic variants in the clinical practice.

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

    Full Text Available Educational systems around the world, and specifically in the United States, have long been awaiting for genuine reform efforts. Technology is often perceived as a panacea, if not as a crucial instrument in any educational reform effort. In a conversation with one of his students, Doctor Johnson discusses how the underlying assumptions embedded in our current schooling practices need to be seriously reviewed before any technology strategy is considered. New understandings, as opposed to mere information, is what schools need to reach in order to transform themselves. Finally, Dr. Johnson provides two brief examples, one in the United States and another in México, were hermeneutical approaches have been used for educational reform endeavors.

    Full Text Available Purpose of study: The main purpose of this study is to investigate the impact of brand extensions on parent brand image. For this purpose Johnson is selected as parent brand for current study. The selected brand extensions are Johnson shampoo, Johnson’s isotonic drinks, Johnson’s sportswear and Johnson’s suntan lotion. Research Methodology: sample was selected from Bradford, UK. Sample consists of consumer of Johnson including males as well as female. Total sample size is 250 and data was collected through self administered questionnaires. Convenience sampling was selected as sampling technique. Results: Correlation analysis indicated negative impact of brand extension on parent brand image if brand extension is done in different brand categories. Perceived brand quality and perceived brand fit of the extension also affect the parent brand image. Conclusion: It is concluded that if brand extension is done in the same product category of parent brand then there is possibly high acceptance for the brand extension rather than in the different product categories.

  19. White Anglo-Saxon hopes and black Americans' Atlantic dreams: Jack Johnson and the British boxing colour bar.

    Science.gov (United States)

    Runstedtler, Theresa

    2010-01-01

    This article examines the controversy surrounding Jack Johnson's proposed world heavyweight title fight against the British champion Bombardier Billy Wells in London (1911). In juxtaposing African Americans' often glowing discussions of European tolerance with the actual white resistance the black champion faced in Britain, including the Home Office's eventual prohibition of the match, the article explores the period's transnational discourses of race and citizenship. Indeed, as white sportsmen on both sides of the Atlantic joined together in their search for a "White Hope" to unseat Johnson, the boxing ring became an important cultural arena for interracial debates over the political and social divisions between white citizens and nonwhite subjects. Although African Americans had high hopes for their hero's European sojourn, the British backlash against the Johnson-Wells match underscored the fact that their local experiences of racial oppression were just one facet of a much broader global problem. At the same time, the proposed prizefight also made the specter of interracial conflict in the colonies all the more tangible in the British capital, provoking public discussions about the merits of U.S. racial segregation, along with the need for white Anglo-Saxon solidarity around the world. Thus, this article not only exposes the underlying connections between American Jim Crow and the racialized fault lines of British imperialism, but it also traces the "tense and tender ties" linking U.S. and African American history with the new imperial history and postcolonial studies.

  20. Spectral model selection in the electronic measurement of the Boltzmann constant by Johnson noise thermometry

    Science.gov (United States)

    Coakley, Kevin J.; Qu, Jifeng

    2017-04-01

    In the electronic measurement of the Boltzmann constant based on Johnson noise thermometry, the ratio of the power spectral densities of thermal noise across a resistor at the triple point of water, and pseudo-random noise synthetically generated by a quantum-accurate voltage-noise source is constant to within 1 part in a billion for frequencies up to 1 GHz. Given knowledge of this ratio, and the values of other parameters that are known or measured, one can determine the Boltzmann constant. Due, in part, to mismatch between transmission lines, the experimental ratio spectrum varies with frequency. We model this spectrum as an even polynomial function of frequency where the constant term in the polynomial determines the Boltzmann constant. When determining this constant (offset) from experimental data, the assumed complexity of the ratio spectrum model and the maximum frequency analyzed (fitting bandwidth) dramatically affects results. Here, we select the complexity of the model by cross-validation—a data-driven statistical learning method. For each of many fitting bandwidths, we determine the component of uncertainty of the offset term that accounts for random and systematic effects associated with imperfect knowledge of model complexity. We select the fitting bandwidth that minimizes this uncertainty. In the most recent measurement of the Boltzmann constant, results were determined, in part, by application of an earlier version of the method described here. Here, we extend the earlier analysis by considering a broader range of fitting bandwidths and quantify an additional component of uncertainty that accounts for imperfect performance of our fitting bandwidth selection method. For idealized simulated data with additive noise similar to experimental data, our method correctly selects the true complexity of the ratio spectrum model for all cases considered. A new analysis of data from the recent experiment yields evidence for a temporal trend in the offset

    Tuberculosis (TB) is caused by the bacterium Mycobacterium tuberculosis and is spread from person to person through the air. TB can be spread in congregate settings, such as school environments, to varying degrees, based on factors including duration of contact and air ventilation (1); therefore, evaluating potential contacts and exposures can be challenging. In February 2015, a student at a Kansas high school received a diagnosis of active pulmonary TB disease. Screening of 385 (91%) school contacts, four (100%) household contacts, and 19 (90%) social contacts resulted in the identification of 50 persons with latent TB infection. Johnson County Department of Health and Environment (JCDHE) Public Health Emergency Preparedness personnel used their experience with points of distribution logistics to optimize testing clinic layouts and implement the incident command structure. Open communication with students, school staff members, the public, and the media about the investigation from the outset was imperative to reduce rumors and unease that can accompany a large communicable disease investigation. The large number of persons needing treatment for latent TB overwhelmed JCDHE's two TB nurses. As a result, JCDHE developed a policy and procedure to allow persons who met eligibility requirements to complete 12 weekly doses of isoniazid and rifapentine treatment using video directly observed therapy (VDOT) rather than traditional in-person directly observed therapy (DOT). This procedure facilitated treatment compliance and completion; among the eligible 15 persons who chose the 12-week VDOT option, 14 (93%) completed treatment. State and local health departments might consider use of VDOT to monitor treatment of persons with latent TB infection.

    Full Text Available OBJECTIVE: Stevens-Johnson Syndrome (SJS is one of the most severe muco-cutaneous diseases and its occurrence is often attributed to drug use. The aim of the present study is to quantify the risk of SJS in association with drug and vaccine use in children. METHODS: A multicenter surveillance of children hospitalized through the emergency departments for acute conditions of interest is currently ongoing in Italy. Cases with a diagnosis of SJS were retrieved from all admissions. Parents were interviewed on child's use of drugs and vaccines preceding the onset of symptoms that led to the hospitalization. We compared the use of drugs and vaccines in cases with the corresponding use in a control group of children hospitalized for acute neurological conditions. RESULTS: Twenty-nine children with a diagnosis of SJS and 1,362 with neurological disorders were hospitalized between 1(st November 1999 and 31(st October 2012. Cases were more frequently exposed to drugs (79% vs 58% in the control group; adjusted OR 2.4; 95% CI 1.0-6.1. Anticonvulsants presented the highest adjusted OR: 26.8 (95% CI 8.4-86.0. Significantly elevated risks were also estimated for antibiotics use (adjusted OR 3.3; 95% CI 1.5-7.2, corticosteroids (adjusted OR 4.2; 95% CI 1.8-9.9 and paracetamol (adjusted OR 3.2; 95% CI 1.5-6.9. No increased risk was estimated for vaccines (adjusted OR: 0.9; 95% CI 0.3-2.8. DISCUSSION: Our study provides additional evidence on the etiologic role of drugs and vaccines in the occurrence of SJS in children.

    Full Text Available Historically, plant distribution typically has been studied with the purpose of learning why a species grows and survives where it does; but why a species does not survive in a particular habitat has rarely been studied, although it may be just as important. According to the US Department of Agriculture, Johnsongrass [Sorghum halepense (L. Pers.; formerly Johnson grass] is listed as an agricultural pest in most states south of the 42nd parallel. Control of Johnsongrass inagricultural fields involves various labor intensive cultural, mechanical, and chemical means. Release of a bio-control agent has not been suitable for intensively cropped areas. An agriculturally important weed and prominent member of early stage secondary succession, Johnsongrass is not present in later stages of prairie succession. Various environmental factors (biotic and abiotic that might be involved in restricting Johnsongrass survival were examined in this research. In two sites in Oklahoma, soil conditions were found to be more favorable for survival and growth of Johnsongrass in undisturbed prairie than in the disturbed areas in which Johnsongrass was found vigorously growing. However, even when its rhizomes were introduced into mature prairie, Johnsongrass did not thrive. In laboratory and field trials, presence of the living dominant prairie grasses or leachate from living or dead leaf blades seemed to influence growth and survival of Johnsongrass rhizomes. The prairie grasses, little bluestem [Schizachyrium scoparium (Michx. Nash] and Indian grass [Sorghastrum nutans (L. Nash], seem to play a similarallelopathic role in restricting the growth of Johnsongrass to outside of the prairies. Looking at this past study might lead to new methods for the future.

  5. Automated classification of interplanetary dust particles: Johnson Space Center Cosmic Dust Catalog Volume 15

    The ``Cosmic Dust Catalog,'' published by the NASA Johnson Space Center (JSC), describes thousands of interplanetary dust particles subjected to preliminary analysis and with labels indicating their origin. However, only about 80% of the particles are assigned unambiguous labels, the labels of the remaining 20% being uncertain. In addition, the Stardust mission results opened up the possibility that some particles classified as terrestrial contaminants are instead of cosmic (cometary) origin. In this article, we present a methodology for automatic classification of particles on the basis of similarity of their X-ray energy dispersive spectrometry spectra. The method is applied to the 467 particles constituting Volume 15 of the catalog. A first part of the analysis is to digitize the spectra from their scanned images. The digitized spectra are subjected to agglomerative clustering, which reveals 16 distinct clusters or compositional types of particles. The Sammon's map is used to visualize the relationship between different clusters; 6 clusters corresponding to cosmic particles and 10 clusters corresponding to terrestrial contaminants are clearly separated on the map indicating overall differences between diverse spectra of cosmic and terrestrial particles. By reconciling labels with the clustering structures, we propose the relabeling of 155 particles including the relabeling of 31 terrestrial contaminants into cosmic particles. The proposed relabeling needs to be confirmed by in-depth study of these particles. The paucity of particles with firmly determined cometary or asteroidal origin makes it difficult to establish whether the spectra based autoclassification can be utilized to discriminate between cometary and asteroidal particles. The methodology presented here can be used to classify all particles published in the catalog, as well as different samples for which comparable spectra are available.

    Directory of Open Access Journals (Sweden)

    Kish Laszlo B.

    2016-03-01

    Full Text Available We introduce two new Kirchhoff-law-Johnson-noise (KLJN secure key distribution schemes which are generalizations of the original KLJN scheme. The first of these, the Random-Resistor (RR- KLJN scheme, uses random resistors with values chosen from a quasi-continuum set. It is well-known since the creation of the KLJN concept that such a system could work in cryptography, because Alice and Bob can calculate the unknown resistance value from measurements, but the RR-KLJN system has not been addressed in prior publications since it was considered impractical. The reason for discussing it now is the second scheme, the Random Resistor Random Temperature (RRRT- KLJN key exchange, inspired by a recent paper of Vadai, Mingesz and Gingl, wherein security was shown to be maintained at non-zero power flow. In the RRRT-KLJN secure key exchange scheme, both the resistances and their temperatures are continuum random variables. We prove that the security of the RRRT-KLJN scheme can prevail at a non-zero power flow, and thus the physical law guaranteeing security is not the Second Law of Thermodynamics but the Fluctuation-Dissipation Theorem. Alice and Bob know their own resistances and temperatures and can calculate the resistance and temperature values at the other end of the communication channel from measured voltage, current and power-flow data in the wire. However, Eve cannot determine these values because, for her, there are four unknown quantities while she can set up only three equations. The RRRT-KLJN scheme has several advantages and makes all former attacks on the KLJN scheme invalid or incomplete.

    Satterwhite, C. E.; McBridge, K. M.; Harrington, R.; Schwarz, C. M.

    2011-01-01

    The ANSMET program began in 1976, and since that time more than 18,000 meteorites have been processed in the Meteorite Processing Lab at Johnson Space Center in Houston, TX[1]. The meteorites are collected and returned to JSC on a freezer truck and remain frozen until they are initially processed. Initial Processing of Meteorites: Initial processing involves drying the meteorites in a nitrogen glove box for 24 to 48 hours, photographing, measuring, weighing and writing a description of the interior and exterior. The meteorite is broken and a representative sample is sent to the Smithsonian Institution for classification. Newsletter & Requests: Once initial processing has been complete and the meteorites have been classified, the information is published in the Antarctic Meteorite Newsletter[2,3]. The newsletter is published twice yearly and is sent electronically to researchers around the world and is also available on line. Researchers are asked to fill out a request form and submit it to the Meteorite Working Group secretary. All sample requests will be reviewed by either the meteorite curator or the Meteorite Working Group de-pending on the type of meteorite and the research being conducted. Processing for Sample Requests: In the meteorite processing lab, meteorite samples are prepared several different ways. Most samples are prepared as chips obtained by use of stainless steel chisels in a chipping bowl or rock splitter. In special situations where a researcher needs a slab the meteorite samples can be bandsawed in a dry nitrogen glove box with a diamond blade, no liquids are ever introduced into the cabinet. The last type of sample preparation is thin/thick sections. The meteorite thin section lab at JSC can prepare standard 30-micron thin sections, thick sections of variable thickness (100 to 200 microns), or demountable sections using superglue. Information for researchers: It is important that re-searchers fill the sample request form completely, in order

  11. An improved electronic determination of the Boltzmann constant by Johnson noise thermometry

    2017-08-01

    Recent measurements using acoustic gas thermometry have determined the value of the Boltzmann constant, k, with a relative uncertainty less than 1  ×  10-6. These results have been supported by a measurement with a relative uncertainty of 1.9  ×  10-6 made with dielectric-constant gas thermometry. Together, the measurements meet the requirements of the International Committee for Weights and Measures and enable them to proceed with the redefinition of the kelvin in 2018. In further support, we provide a new determination of k using a purely electronic approach, Johnson noise thermometry, in which the thermal noise power generated by a sensing resistor immersed in a triple-point-of-water cell is compared to the noise power of a quantum-accurate pseudo-random noise waveform of nominally equal noise power. The experimental setup differs from that of the 2015 determination in several respects: a 100 Ω resistor is used as the thermal noise source, identical thin coaxial cables made of solid beryllium-copper conductors and foam dielectrics are used to connect the thermal and quantum-accurate noise sources to the correlator so as to minimize the temperature and frequency sensitivity of the impedances in the connecting leads, and no trimming capacitors or inductors are inserted into the connecting leads. The combination of reduced uncertainty due to spectral mismatches in the connecting leads and reduced statistical uncertainty due to a longer integration period of 100 d results in an improved determination of k  =  1.380 649 7(37)  ×  10-23 J K-1 with a relative standard uncertainty of 2.7  ×  10-6 and a relative offset of 0.89  ×  10-6 from the CODATA 2014 recommended value. The most significant terms in the uncertainty budget, the statistical uncertainty and the spectral-mismatch uncertainty, are uncorrelated with the corresponding uncertainties in the 2015 measurements.

    Digital flood-inundation maps for a 6.4-mile upper reach of Indian Creek from College Boulevard to the confluence with Tomahawk Creek, a 3.9-mile reach of Tomahawk Creek from 127th Street to the confluence with Indian Creek, and a 1.9-mile lower reach of Indian Creek from the confluence with Tomahawk Creek to just beyond the Kansas/Missouri border at State Line Road in Johnson County, Kansas, were created by the U.S. Geological Survey in cooperation with the city of Overland Park, Kansas. The flood-inundation maps, which can be accessed through the U.S. Geological Survey Flood Inundation Mapping Science Web site at http://water.usgs.gov/osw/flood_inundation/, depict estimates of the areal extent and depth of flooding corresponding to selected water levels (stages) at the U.S. Geological Survey streamgages on Indian Creek at Overland Park, Kansas; Indian Creek at State Line Road, Leawood, Kansas; and Tomahawk Creek near Overland Park, Kansas. Near real time stages at these streamgages may be obtained on the Web from the U.S. Geological Survey National Water Information System at http://waterdata.usgs.gov/nwis or the National Weather Service Advanced Hydrologic Prediction Service at http://water.weather.gov/ahps/, which also forecasts flood hydrographs at these sites.Flood profiles were computed for the stream reaches by means of a one-dimensional step-backwater model. The model was calibrated for each reach by using the most current stage-discharge relations at the streamgages. The hydraulic models were then used to determine 15 water-surface profiles for Indian Creek at Overland Park, Kansas; 17 water-surface profiles for Indian Creek at State Line Road, Leawood, Kansas; and 14 water-surface profiles for Tomahawk Creek near Overland Park, Kansas, for flood stages at 1-foot intervals referenced to the streamgage datum and ranging from bankfull to the next interval above the 0.2-percent annual exceedance probability flood level (500-year recurrence interval).

    1999-07-01

    The Daniel-Johnson dam is located 800 km northeast of Montreal, PQ, and is 1314 m in length and 214 m high. Just after completion of dam construction different types of cracks started to appear on the upstream and downstream faces. During and after the construction of the dam, numerous cracks and joints were grouted in order to reduce water infiltration. In some cases, as a result of high injection pressures and inaccurate methods, the injections provoked the propagation of the existing cracks or the initiation of new ones. Because of this situation and to determine the contribution of injection to dam safety, in 1985, Hydro-Quebec applied a moratorium on all future injection work on the dam. Research work was initiated in 1986 in the areas of grouting materials, methods, equipment and behavioral analysis to establish a safe method for the injection of the cracks. A committee was formed in 1993 with members from various groups, in order to: carry out extensive behavioral analysis of the Arch 5-6 dam, carry out an investigation program in order to determine the cause of the increase of the water infiltration, undertake a structural analysis program in order to evaluate the impact of an injection on the safety of the dam, and identify the proper method and injection products to use. In 1997, as a result of the progress of the structural analysis studies and the injection research project, a decision was made to proceed with the injection of the dam. A description is included of the results of the investigation, recommendations and results of the injection research project, as well as some details of the grouting campaign carried out in January 1999. On the whole, a better knowledge was acquired of the structure, of the plunging cracks and the behaviour of the dam during the injection. In the field of injection methods, materials and equipment, research work was invaluable when it came to the injection of micro-fine cracks in concrete dams. 5 refs., 8 figs.

    The Astromaterials Acquisition and Curation Office at NASA's Johnson Space Center (hereafter JSC curation) is the past, present, and future home of all of NASA's astromaterials sample collections. JSC curation currently houses all or part of nine different sample collections: (1) Apollo samples (1969), (2) Lunar samples (1972), (3) Antarctic meteorites (1976), (4) Cosmic Dust particles (1981), (5) Microparticle Impact Collection (1985), (6) Genesis solar wind atoms (2004); (7) Stardust comet Wild-2 particles (2006), (8) Stardust interstellar particles (2006), and (9) Hayabusa asteroid Itokawa particles (2010). Each sample collection is housed in a dedicated clean room, or suite of clean rooms, that is tailored to the requirements of that sample collection. Our primary goals are to maintain the long-term integrity of the samples and ensure that the samples are distributed for scientific study in a fair, timely, and responsible manner, thus maximizing the return on each sample. Part of the curation process is planning for the future, and we also perform fundamental research in advanced curation initiatives. Advanced Curation is tasked with developing procedures, technology, and data sets necessary for curating new types of sample collections, or getting new results from existing sample collections [2]. We are (and have been) planning for future curation, including cold curation, extended curation of ices and volatiles, curation of samples with special chemical considerations such as perchlorate-rich samples, and curation of organically- and biologically-sensitive samples. As part of these advanced curation efforts we are augmenting our analytical facilities as well. A micro X-Ray computed tomography (micro-XCT) laboratory dedicated to the study of astromaterials will be coming online this spring within the JSC Curation office, and we plan to add additional facilities that will enable nondestructive (or minimally-destructive) analyses of astromaterials in the near

  16. Uncertainty from synergistic effects of multiple parameters in the Johnson and Ettinger (1991) vapor intrusion model

    Migration of volatile chemicals from the subsurface into overlying buildings is known as vapor intrusion (VI). Under certain circumstances, people living in homes above contaminated soil or ground water may be exposed to harmful levels of these vapors. VI is a particularly difficult pathway to assess, as challenges exist in delineating subsurface contributions to measured indoor-air concentrations as well as in adequate characterization of subsurface parameters necessary to calibrate a predictive flow and transport model. Often, a screening-level model is employed to determine if a potential indoor inhalation exposure pathway exists and, if such a pathway is complete, whether long-term exposure increases the occupants' risk for cancer or other toxic effects to an unacceptable level. A popular screening-level algorithm currently in wide use in the United States, Canada and the UK for making such determinations is the "Johnson and Ettinger" (J&E) model. Concern exists over using the J&E model for deciding whether or not further action is necessary at sites as many parameters are not routinely measured (or are un-measurable). Many screening decisions are then made based on simulations using "best estimate" look-up parameter values. While research exists on the sensitivity of the J&E model to individual parameter uncertainty, little published information is available on the combined effects of multiple uncertain parameters and their effect on screening decisions. This paper presents results of multiple-parameter uncertainty analyses using the J&E model to evaluate risk to humans from VI. Software was developed to produce automated uncertainty analyses of the model. Results indicate an increase in predicted cancer risk from multiple-parameter uncertainty by nearly a factor of 10 compared with single-parameter uncertainty. Additionally, a positive skew in model response to variation of some parameters was noted for both single and multiple parameter uncertainty analyses

  17. Cefotaxime-induced Stevens and ndash;Johnson syndrome: a case report

    Full Text Available Stevens and ndash;Johnson syndrome (SJS and toxic epidermal necrolysis are two forms of a life-threatening skin condition, in which cell death causes the epidermis to separate from the dermis. The syndrome is thought to be a hypersensitivity complex that affects the skin and the mucous membranes. The most well-known causes are certain medications, but it can also be due to infections, or more rarely, cancers. SJS usually begins with fever, sore throat, and fatigue, which is commonly misdiagnosed and therefore treated with antimicrobials. Ulcers and other lesions begin to appear in the mucous membranes, almost always in the mouth and lips, but also in the genital and anal regions. Conjunctivitis of the eyes occurs in about 30% of children who develop SJS. A rash of round lesions about an inch across arises on the face, trunk, arms and legs, and soles of the feet, but usually not the scalp. SJS is a medical emergency that usually requires hospitalization. Treatment focuses on eliminating the underlying cause, controlling symptoms and minimizing complications. Recovery after SJS can take weeks to months, depending on the severity of the condition. If it was caused by a medication, then the medication and others closely related to it has to be avoided permanently. An 18-month-old male child was admitted to a private health setup in Kolar with the complaints of peeling and discoloration of the skin, ulcerations in the oral cavity, eyelids, and genitalia. The parents gave the history of cefotaxime injection being administered to the child for treating typhoid 20 days back. Seven days after the administration of cefotaxime, the child had developed maculo-papular lesions all over the body. Later on there was peeling and discoloration of the skin. Itching was present. Ulcerations in the oral cavity, eyelids and genitalia were also noticed by the parents, who then brought the child to the health care center. According to the Naranjo's adverse drug

    We propose a hybrid Monte Carlo (HMC) technique applicable to high-dimensional multivariate normal distributions that effectively samples along chaotic trajectories. The method is predicated on the freedom of choice of the HMC momentum distribution, and due to its mixing properties, exhibits sample-to-sample autocorrelations that decay far faster than those in the traditional hybrid Monte Carlo algorithm. We test the methods on distributions of varying correlation structure, finding that the proposed technique produces superior covariance estimates, is less reliant on step-size tuning, and can even function with sparse or no momentum re-sampling. The method presented here is promising for more general distributions, such as those that arise in Bayesian learning of artificial neural networks and in the state and parameter estimation of dynamical systems.

    Monte Carlo studies involving real time dynamics are severely restricted by the sign problem that emerges from highly oscillatory phase of the path integral. In this letter, we present a new method to compute real time quantities on the lattice using the Schwinger-Keldysh formalism via Monte Carlo simulations. The key idea is to deform the path integration domain to a complex manifold where the phase oscillations are mild and the sign problem is manageable. We use the previously introduced "contraction algorithm" to create a Markov chain on this alternative manifold. We substantiate our approach by analyzing the quantum mechanical anharmonic oscillator. Our results are in agreement with the exact ones obtained by diagonalization of the Hamiltonian. The method we introduce is generic and in principle applicable to quantum field theory albeit very slow. We discuss some possible improvements that should speed up the algorithm.
