    Full Text Available En Colombia ya no se lee a Valery Larbaud. Los escritores jóvenes lo ignoran por completo, y mis compañeros de generación, estoy seguro de ello, no han vuelto a abrir un solo libro de este escritor que fue, para los muchachos de 1925, un revelador de cosas extraordinarias y nuevas, en el campo de la literatura. Había nacido en 1880, y su primera obra, la más difundida entonces y aquella que, desde su publicación, fue considerada por el propio autor como su testamento literario, A. O. Barnaboot, aparecida en París en vísperas de la primera guerra mundial, solo fue conocida en Bogotá hacia 1920, vale decir, en la época llamada del "armisticio".

    2010-01-01

    Frank Blythe, one of the very first engineers engaged in the CERN adventure, passed away on October 22. Born and educated in Salford (England), after a time spent at Metropolitan-Vickers in Manchester, in January 1954 he joined the group at the Nuclear Physics Research Laboratory in Liverpool that was working on the first CERN accelerator, the Synchrocyclotron (SC). At that time CERN had not yet officially been constituted, yet had a well defined work programme, the design and construction work being carried out in various European laboratories. In Liverpool the work included the SC vacuum and cooling system, radiation shielding, experimental areas and beams. By the end of 1954, Frank reached the CERN premises in Geneva, and contributed significantly to the successful construction work of the Synchrocyclotron. He later became responsible for the drawing office and the mechanical workshop (Engineering Group) attached to the MSC Division, and also serving the NP/EP Division. He kept this position until ...

  10. Improving access to research outcomes for innovation in agriculture and forestry: the VALERIE project

    Directory of Open Access Journals (Sweden)

    Full Text Available Many excellent results are obtained in agricultural and forestry research projects, but their practical adoption is often limited. The aim of the European project VALERIE is to increase the transfer and application of innovations produced by research in agriculture and forestry, by facilitating their integration into management practices. The project is still ongoing and the results illustrated in this paper are still temporary and subject to being improved. Here we present the methodology used in VALERIE to extract and summarise knowledge for innovation from research documents with the aim of making it available to final users through ask-Valerie.eu; we also report on current progress. The tasks associated with extracting and summarising knowledge are centred on: i an ontology; ii a document base; and iii a system (ask-Valerie.eu that allows users to effectively search the document base. An ontology defines a set of concepts and the relations between them. The VALERIE ontology is built by experts in the agricultural and forestry domain and contains 6169 concepts (21st October 2016. The document base is the collection of documents in which the system searches. The VALERIE document base includes scientific and practical documents derived from various sources, written in any of a number of languages. All documents contained in the document base are annotated using the ontology: each term (a word or a short phrase in the document that matches a concept in the VALERIE-ontology is linked to that concept. Annotation is an automated process that takes place whenever a document is added to the document base. The document base contains 4278 documents (October 2016. Among them, there are 201 minifactsheets written by members of the VALERIE project, each describing an innovation with: a short description of the innovation, a list of correlated projects, and some links to scientific and practical documents. ask-Valerie.eu searches documents and fragments of

    2008-01-01

    Amsterdam, summer 1952: it was here that the first recruits for CERN ‘s 600 MeV Synchrocyclotron project met Frank Krienen for the first time. A young assistant to Prof. C.J. Bakker at the Physics Institute, he soon became the mastermind behind the most daring aspects of the project: the frequency modulating circuit, based on a vibrating tuning fork, was his creation. He was a respected and inspiring leader throughout the construction period of the accelerator and, at the same time, an older brother and an exacting mentor. Frank later devoted himself to developing particle detectors, in particular spark wire chambers using different types of readout. His next major involvement at CERN was his contribution to the glorious g-2 saga. Frank’s contributions to the last experiment of the anomalous magnetic moment of the muon (g-2) done at CERN (1969-1977) were very important in many aspects. The last (g-2) experiment was based on many...

  17. Obituary: Frank Culver Jones, 1932-2007

    Science.gov (United States)

    Ormes, Johnathan F.; Streitmatter, Robert E.

    2007-12-01

    Frank C. Jones, an emeritus theoretical physicist at NASA, died May 2, 2007 at age 74 after a struggle with a rare form of cancer. He died at his home in Silver Spring, Maryland, surrounded by his family. Frank was born July 30, 1932 in Fort Worth, Texas, the oldest of three boys. His parents were Kenneth Hugh and Nancy Culver Jones. Frank's father was a lawyer, and his grandfather was a Methodist minister. Frank graduated from Rice University in 1954 and earned a master's degree in 1955 and a doctorate in 1961, both in physics, from the University of Chicago. He did his graduate work with Prof. John Simpson. Dr. Jones began his professional career as an instructor in physics at Princeton University before joining NASA's Goddard Space Flight Center in 1963 as a National Research Council associate. He subsequently became a member of the Theory Division and the Laboratory for High Energy Astrophysics. His area of expertise was the origin, transport, and electromagnetic interactions of cosmic rays. His particular focus was the stochastic physics related to the diffusion of particles in random fields, plasma turbulence, and the shock acceleration of charged particles in collisionless plasmas. From 1993 to 1995, Frank was head of Goddard's Theoretical High Energy Astrophysics Office and continued to serve as Head of the Theory group. In 2003 he served as Acting Chief of the Laboratory for High Energy Astrophysics. He retired in 2005 and continued his affiliation with NASA as an emeritus scientist at Goddard until his death. As a youngster, Frank showed the signs of curiosity and initiative that indicated he might become an experimentalist. At the memorial service for Frank, his brother related the stories of how Frank had rigged a hidden microphone to play through the family television as his brother courted a young woman on the front porch swing, and how one of Frank's early chemistry experiments caused all the family silverware to turn black. Although Frank started

    Hanging in the basement of Kirkwood Observatory on the Indiana University campus is a battered sign, dated Aug 31, 1932, announcing "Indiana Univ. Eclipse Station." While the path of totality passed well north of Bloomington, IN, where only 80% of the Sun's disk was covered, the eclipse made a lasting impression on the young Frank Kelley Edmondson, then an undergraduate student at Indiana University. Frank was born on August 1, 1912, in Milwaukee, Wisconsin, to Clarence Edward Edmondson and Marie (Kelley) Edmondson. Growing up in Seymour, Indiana, he became interested in astronomy at an early age, reading voraciously from the "Book of Knowledge" at an aunt's house (The Book of Knowledge Set of Encyclopedias). He learned magic and was acquainted with Blackstone, the magician. He took ballet lessons and performed with his brother. He was a YMCA Camp Counselor at Camp Bedford where he taught natural sciences to the campers. He worked one summer as a cook on an ore boat on Lake Michigan. In high school he sang in a musical - and wore a false beard. In 1944 he grew his own beard, one of only two on the IU faculty at the time, and he kept the beard all the many years since. In 1996, Frank was elected to the Shields High School "Wall of Fame." After graduating from Shields High School in 1929, Frank enrolled at Indiana University. He was a member of the IU intercollegiate debate team for four years. He was initiated into Phi Beta Kappa as a junior and was a member of Sigma Xi. He graduated in 1933 and earned a Master's degree in 1934 based on a thesis ("An Analysis of the Radial Velocities of Twenty-One Globular Star Clusters") and professional experience earned while holding the Lawrence Fellowship at the Lowell Observatory in Flagstaff, Arizona in 1934-35, where he worked as an observing assistant to Clyde Tombaugh. Despite his close association with Lowell, Tombaugh, and Pluto, Frank approved of the decision of the International Astronomical Union in 2006 to change

    Full Text Available In 1937 the First All-Union Congress of Soviet Architects was held in Moscow. The congress brought  architects from all areas of the  Soviet Union. Under the auspices of Vsesoiuvnoe Obshchestvo Kul'turnoi Sviazi s zagranitsei (VOKS it invited international architects from Europe and North and South America.  The Organizing Committee of the Union of Soviet Architects invited Frank Lloyd Wright from the United States. Frank Lloyd Wright presented his philosophy and exhibited his work, specifically his designs for the weekend home for E. J. Kaufmann "Fallingwater" and the drawings for the S.C. Johnson Administration. Frank Lloyd Wright's presentation did not focus heavily on the architecture but, rather the spirit of the Russian and Soviet vision.

  20. Rediscovery of Otto Frank's contribution to science.

    Kuhtz-Buschbeck, Johann P; Drake-Holland, Angela; Noble, Mark I M; Lohff, Brigitte; Schaefer, Jochen

    2018-06-01

    In the late 19th century, German physiologist Otto Frank (1865-1944) embarked on a near life-long research program of laying down the mathematical, methodological, and theoretical foundations in order to understand and define the performance of the heart and circulatory system in all their complexity. The existence of the "Frank-Starling law" testifies to this. Two of his seminal publications have been translated into English previously, introducing Frank's research on the dynamics of the heart and the arterial pulse to a wider audience. It is likely that there are a host of other comparable achievements and publications of Frank that are still unknown to the international scientific (cardiological and physiological) community. However, their influence can still be felt and seen in modern cardiology and cardio-physiology, such as in the development of modern interactive simulating and teaching programs. We have translated and commented on ten of these papers, which can be read in parallel with the German originals. These publications show a wealth of theoretical assumptions and projections regarding the importance of the sarcomere, the development of models of contraction, thermo-dynamical considerations for muscular activity, differences between cardiac and skeletal muscles, problems related to methodology and measurement, and the first pressure-volume diagram (published 120 years ago). These topics were envisioned by Frank long before they became a focus of subsequent modern research. Nowadays, frequent measurements of pressure-volume relationships are made in research using the pressure-volume conductance catheter technique. In commenting Frank's scientific topics, we try to show how interconnected his thinking was, and thus how it enabled him to cover such a wide range of subjects. Copyright © 2018 The Authors.

  2. Obituary: Frank J. Low (1933-2009)

    Science.gov (United States)

    McCarthy, Don

    2011-12-01

    Frank James Low was born on November 23, 1933, in Mobile, Alabama. He received his undergraduate degree in physics from Yale University in 1955, and his Ph.D. in physics from Rice University in 1959. He worked at Texas Instruments, NRAO, Rice University, and spent most of his career at The University of Arizona with Steward Observatory and the Lunar and Planetary Laboratory. To honor his fundamental insight and innovations that revolutionized the fields of infrared and airborne astronomy, Frank received the Helen B. Warner Prize (1968), the Joseph Weber Award (2003), shared the Rumford Prize in physics (1986), the Karl Jansky Lectureship (2006), and the Bruce Medal (2006) for lifetime contributions in astronomy. This year the world celebrates the International Year of Astronomy, commemorating the accomplishments of Galileo. There are great parallels between Frank and Galileo. After developing a revolutionary low-temperature detector, Frank re-engineered and optimized telescopes for infrared performance. He not only oriented them to the heavens but also placed them there throughout Earth's atmosphere and to the Moon. He made fantastic new discoveries from the Sun throughout the Universe. He radically changed the way the entire world looks at the Universe and impacted generations of new scientists as well as the general public. Frank's level of innovation is stunning and diverse. Chopping and undersized secondary mirrors, cold baffling, cryogenic designs, "Low Dewars," Helium-3 systems, JFET amplifiers for the IRAS satellite, airborne astronomy, the silver-coated 28-inch survey telescope, the MMT, the 36-foot radio dish, Apollo 17 radiometer, television detector systems, infrared microscopes, and on and on. His insights enabled the IRAS and Spitzer missions and contributed to Spacelab2, KAO, SOFIA, NICMOS/HST, JWST, etc. He also established a small business (Infrared Laboratories Inc.) that for more than 40 years has supplied instrumentation to astronomers and semi

  3. Mirrors in Russian Decadent and Symbolist Prose: Valery Briusov and Dmitry Merezhkovsky

    Directory of Open Access Journals (Sweden)

    Kirsten Lodge

    2010-06-01

    Full Text Available Examining mirror imagery in the prose works “In the Mirror” by Valery Briusov and The Resurrected Gods: Leonardo da Vinci by Dmitry Merezhkovsky, both published in 1902, this article situates the Russian Decadent and Symbolist associations of the mirror in the pan-European literary and philosophical context. The mirror constitutes the threshold of manifold oppositions, including life and art, life and death, and reality and dream or imagination. It is a realm of alternative reality, magical and seductive, as in Briusov’s story, or potentially both demonic and divine, as in Merezhkovsky’s novel. In accordance with the Romantic tradition as well as Decadent and Symbolist iconography, mirror imagery in these two works is inseparable from questions of the nature of art and the power of artistic creation.

  4. Frank Capra and Elia Kazan, American outsiders

    Directory of Open Access Journals (Sweden)

    Yves Carlet

    2010-11-01

    Full Text Available Frank Capra and Elia Kazan both came to the United States as children. From immigrant stock, each experienced the effects of being looked down upon as outsiders to Anglo culture. Based on the two men’s autobiographical accounts, together with their films and biographical writings about them, this article examines the routes by which they sought entry into the dominant culture. This process would require the rejection, in each case, of part of his family heritage. It would lead to very different attitudes to ethnicity in their films: Kazan demonstrated interest in the subject, whereas Capra largely suppressed it. The article underlines other “covert dialogues” in the films directed by the two men. It shows that they most diverged over issues of sexuality and the later rediscovery of their ethnic roots.

    2015-01-01

    This article examines the poetic contribution of Valerie Gillies, Edinburgh Makar (or poet of the city) from 2005-2008, to the Edinburgh Marie Curie Hospice Quiet Room, a new contemplation space for patients, families, and staff. In collaboration with others, Gillies created a transitional space for the Quiet Room, centered on the display of her sonnet, "A Place Apart." This space functions to comfort visitors to the Quiet Room by relocating them in their surroundings and offering the solace provided by nature and history. With this project, her first as Edinburgh Makar, Gillies redefines the role of the poet as healer and advocates for newer forms of palliative care that focus on patients' spiritual and emotional, as well as physical, wellbeing.

  20. Early educator-supervised student rocketry: The galcit rocket research project, 1936-1939. A tribute to Frank J. Malina

    Science.gov (United States)

    James, George S.; Winter, Frank H.

    Dr. Frank J. Malina, (1912-1981) is best known to members of the International Astronautical Federation and the International Academy of Astronautics for his deep commitment to, and active involvement in, both organizations; to his associates at UNESCO for his leadership in organizing the UNESCO Division of Scientific Research; to members of the art world for his kinetic paintings and editorship of the journal Leonardo; and to aerospace historians for his co-founding, with Dr. Theodore von Karman (1881-1963), of the Jet Propulsion Laboratory with its World War II development of rocket takeoff assist units for aircraft and, after WWII, America's first production sounding rocket, the WAC Corporal. However, Frank Malina has received little recognition from aerospace educators for his equally pioneering efforts on their behalf. This paper highlights Dr. Malina's efforts not only as an early participant in educator-supported student rocketry but also in helping establishing some of the guiding principles of this field of science motivation. As Dr. Malina noted in 1968, upon becoming one of the founding members of the Supervision of Youth Research Experiments (SYRE) subcommittee of the IAF's Education Committee, the fundamental safety and educational ground rules of: (A) qualified supervision, (B) proper safety facilities, and (C) professionally designed equipment, conceived almost fifty years ago, are equally valid to today's supervised youth rocketry space-related experiment educational programs.

    The Frank polyphase sequence has been applied to pulsed EPR of triarylmethyl radicals at 256MHz (9.1mT magnetic field), using 256 phase pulses. In EPR, as in NMR, use of a Frank sequence of phase steps permits pulsed FID signal acquisition with very low power microwave/RF pulses (ca. 1.5m......W in the application reported here) relative to standard pulsed EPR. A 0.2mM aqueous solution of a triarylmethyl radical was studied using a 16mm diameter cross-loop resonator to isolate the EPR signal detection system from the incident pulses.

  3. Recycling Frank: Spontaneous emergence of homochirality in noncatalytic systems

    Science.gov (United States)

    2004-01-01

    In this work, we introduce a prebiotically relevant protometabolic pattern corresponding to an engine of deracemization by using an external energy source. The spontaneous formation of a nonracemic mixture of chiral compounds can be observed in out-of-equilibrium systems via a symmetry-breaking phenomenon. This observation is possible thanks to chirally selective autocatalytic reactions (Frank's model) [Frank, F. C. (1953) Biochim. Biophys. Acta 11, 459–463]. We show that the use of a Frank-like model in a recycled system composed of reversible chemical reactions, rather than the classical irreversible system, allows for the emergence of a synergetic autoinduction from simple reactions, without any autocatalytic or even catalytic reaction. This model is described as a theoretical framework, based on the stereoselective reactivity of preexisting chiral monomeric building blocks (polymerization, epimerization, and depolymerization) maintained out of equilibrium by a continuous energy income, via an activation reaction. It permits the self-conversion of all monomeric subunits into a single chiral configuration. Real prebiotic systems of amino acid derivatives can be described on this basis. They are shown to be able to spontaneously reach a stable nonracemic state in a few centuries. In such systems, the presence of epimerization reactions is no more destructive, but in contrast is the central driving force of the unstabilization of the racemic state. PMID:15548617

  5. Cultured to Fail? Representations of Gender-Entangled Urban Women in Two Short Stories by Valerie Tagwira

    Directory of Open Access Journals (Sweden)

    Oliver Nyambi

    2014-07-01

    Full Text Available There is a subtle yet discernible connection between the post-2000 political power struggle and the gender struggle in Zimbabwe. In both cases, a patriarchal power hierarchy shaped by tradition and history is perpetuated and justified as the mark of the nation’s unique identity. In cultural, political, and economic spheres, the status of most urban Zimbabwean women is still reflected as inferior to that of most men. During this economic and political crisis period, the prevailing gender power-relations evolved into gendered appraisals of the impact of the crisis and this created the potential for rather universal and androcentric conclusions. The consequent eclipse of female-centric voices of the political and gender struggle tends to suppress women’s perspectives, consequently inhibiting a gender-inclusive imagining of the nation. This article argues that discourses about gender struggle in Zimbabwe’s post-2000 crisis have not sufficiently addressed the question of space; that is, the significance of the oppressed women’s physical and social space in shaping their grievances and imaginings of exit routes. Similarly, the article argues that representations of this historic period in literary fiction have accentuated the wider political and economic struggles at the expense of other (especially gender struggles, thereby rendering them inconsequential. Using two short stories by Valerie Tagwira (“Mainini Grace’s Promise” and “The Journey”, the article explores the stories’ focalization of gender-entangled women in an urban space to understand the literary evocation of the condition of women caught up in a crisis in urban settings.

  6. Digital Documentation of Frank Lloyd Wright's Masterpiece, Fallingwater

    2017-08-01

    Since 1988, the professional staff of Architectural Preservation Studio (APS) has been involved with the conservation of Frank Lloyd Wright's Fallingwater in Mill Run, PA. Designed and erected from 1935 to 1939 as a weekend home for the Kauffman family, the complex consists of the main house and guest house. After five years of reports and prototype repairs, we produced a two-volume master plan. Using original Frank Lloyd Wright drawings from Avery Library as background drawings, we measured every surface and reproduced the drawings in CAD, also developing elevations of every room. Stone-by-stone drawings of every flagstone floor and terrace scheduled to be lifted were also created using overlapping film photography that was assembled into a photo mosaic. By 2005, we designed, administered and completed a four-phase exterior restoration, with the paint-stripping and repainting of interior rooms being performed during the brief winter period when the building is closed to the public on an ongoing basis. In 2016, we were invited back to the site to review conditions and advise on routine maintenance. At that time we proposed to re-document the buildings, this time using laser-scanning. Laser-scanning of the exterior was performed in May of 2016, and of the interior in March 2017, each over the course of four days. This paper will make a comparison between manual and digital techniques in terms of Fallingwater's documentation.

  9. Küsimus „vene mõjust” Friedebert Tuglase artiklis „Valeri Brjussov”. The Question of Russian Influence on Friedebert Tuglas’ article ”Valeri Brjussov”

    Directory of Open Access Journals (Sweden)

    Lea Pild

    2012-04-01

    Full Text Available This article undertakes to examine a problem that has interested many Estonian scholars for at least a century and a half – the question of the role of Russian literature in the development of Estonian literature. Friedebert Tuglas, leader of the Young Estonia movement, and recognized prose writer, critic, and literary historian, was significantly engaged with this question. In his essay on Valeri Brjussov, published in the 9th issue of the literary magazine Looming in 1924, Tuglas presents an unusual summary of the arguments over ”Russian influence”. As indicated in the subtitle, (”On the Occasion of his Death”, Tuglas’ essay on Brjussov grew out of a talk he gave in the Tartu University main hall on the anniversary of the death of the leader of the Russian symbolists. On closer examination, however, one can see a rich texture of connections between this essay and many of Tuglas’ literary-historical and critical articles in which he engages in polemic with the opponents of Young Estonia’s aesthetic program. As we know, this polemic was not limited to the first two decades of the 20th century, but continued in the 1920s and 1930s, ”when the proponents of new realism came to criticize Young Estonia’s perspectives on art”. One of the main disputed topics was the question of literary ”influences” (”borrowings”. Many of the critics of the Young Estonians accused them of the lack of literary and cultural autonomy, and of dependence on foreign models. From the beginning of the Young Estonia, the sharpest of these polemics concerned relations with Russian literature. According to Tuglas, Young Estonia, which aligned itself first and foremost with the literature of western Europe, also sought the same ”Europeanness” in Russian modernist literature; this can be seen in Estonian literature of the decade 1905–1915. With this approach to the literary process one can interpret the question of ”Russian influence” on

  14. Diagonal Earlobe Crease (Frank's Sign): A Predictor of Cerebral Vascular Events.

    Science.gov (United States)

    Nazzal, Saleh; Hijazi, Basem; Khalila, Luai; Blum, Arnon

    2017-11-01

    Frank's sign was first described in 1973 by an American physician (Sonders T. Frank). It is a diagonal crease in the earlobe that starts from the tragus to the edge of the auricle in an angle of 45° in varying depths. Frank's sign was described as a predictor of future coronary heart disease and peripheral vascular diseases. The aim of the study was to examine the association between Frank's sign and the development of ischemic stroke. This was a prospective study that enrolled consecutive patients admitted with an acute ischemic stroke. Frank's sign was tested in both ears. Clinical data included age, gender, type 2 diabetes mellitus, and hypertension. The study was approved by the institutional review board (the institutional ethics committee). A total of 241 consecutive patients who were hospitalized with an acute stroke and were eligible to take part in the study were recruited. Frank's sign was present in 190 patients (78.8%). Patients were divided according to clinical findings and the findings from brain computed tomography. There were 153 patients with transient ischemic attacks (63.6% of the patients) and 88 with cerebrovascular accidents (36.4% of the patients). A total of 112 patients with transient ischemic attacks had Frank's sign (73.2%), and 78 patients with cerebrovascular accidents had Frank's sign (88.6%), with a statistically significant difference (P <.01). Frank's sign could predict ischemic cerebrovascular events. Patients with classical cardiovascular risk factors had Frank's sign at a higher frequency. Copyright © 2017 Elsevier Inc.

  20. SUSTAINABLE ORIGINS IN ARCHITECTURE OF FRANK LLOYD WRIGHT

    Directory of Open Access Journals (Sweden)

    Martina Zbašnik-Senegačnik

    2012-10-01

    Full Text Available Frank Lloyd Wright is the greatest American architect and oneof the greatest architects the world. His career began at theend of the 19th century, during the great architectural boom inChicago, under the mentorship of Louis Henry Sullivan, fromwhom he adopted and then perfected the concepts of organicarchitecture and the Prairie house. During the Depressionyears, Wright developed a cheaper and simpler variant of thePrairie house: the Usonian house.Wright's architecture is characterised by an entirely newapproach to building design, particularly the design of houses.He reduced the number of rooms by combining their functionsin a large living space with a central fireplace. He used largeglazed areas to connect the external environment of the housewith the interior. The natural environment of the prairie wasthe inspiration for the horizontal lines that characterised hisarchitecture. His buildings are low in height, close to humanscale and with a great feeling for the natural setting in whichthey are built. He selected materials from the surroundingarea and the principal decoration of his architecture was thenatural structure of the material.The paper presents the ideas of organic architecture, thePrairie house, the Usonian house, along with the best examplesof Wright's architecture and the criteria he employed in theselection of materials and construction technologies. Theenvironmental aspect of his philosophy of the use of materialsis considered in the discussion section.Wright may be considered a pioneer of sustainable architecture.

  1. Frank Gilbreth and health care delivery method study driven learning.

    Science.gov (United States)

    Towill, Denis R

    2009-01-01

    The purpose of this article is to look at method study, as devised by the Gilbreths at the beginning of the twentieth century, which found early application in hospital quality assurance and surgical "best practice". It has since become a core activity in all modern methods, as applied to healthcare delivery improvement programmes. The article traces the origin of what is now currently and variously called "business process re-engineering", "business process improvement" and "lean healthcare" etc., by different management gurus back to the century-old pioneering work of Frank Gilbreth. The outcome is a consistent framework involving "width", "length" and "depth" dimensions within which healthcare delivery systems can be analysed, designed and successfully implemented to achieve better and more consistent performance. Healthcare method (saving time plus saving motion) study is best practised as co-joint action learning activity "owned" by all "players" involved in the re-engineering process. However, although process mapping is a key step forward, in itself it is no guarantee of effective re-engineering. It is not even the beginning of the end of the change challenge, although it should be the end of the beginning. What is needed is innovative exploitation of method study within a healthcare organisational learning culture accelerated via the Gilbreth Knowledge Flywheel. It is shown that effective healthcare delivery pipeline improvement is anchored into a team approach involving all "players" in the system especially physicians. A comprehensive process study, constructive dialogue, proper and highly professional re-engineering plus managed implementation are essential components. Experience suggests "learning" is thereby achieved via "natural groups" actively involved in healthcare processes. The article provides a proven method for exploiting Gilbreths' outputs and their many successors in enabling more productive evidence-based healthcare delivery as summarised

    We report on a patient with Frank-Ter Haar syndrome that is associated with high intraocular pressures. A 21-day-old male patient was referred to our clinic for surgical treatment of congenital glaucoma. On ophthalmic examination, he had buphthalmos, mild corneal edema and high IOP readings in both eyes. The patient underwent uneventful trabeculotomy surgery, bilaterally. Marked bilateral anterior iris insertion was noted during the surgery. Childhood glaucoma may be associated with Frank-Ter Haar syndrome.

  5. Lack of Frank Agrammatism in the Nonfluent Agrammatic Variant of Primary Progressive Aphasia

    Directory of Open Access Journals (Sweden)

    Naida L. Graham

    2016-09-01

    Full Text Available Background/Aims: Frank agrammatism, defined as the omission and/or substitution of grammatical morphemes with associated grammatical errors, is variably reported in patients with nonfluent variant primary progressive aphasia (nfPPA. This study addressed whether frank agrammatism is typical in agrammatic nfPPA patients when this feature is not required for diagnosis. Method: We assessed grammatical production in 9 patients who satisfied current diagnostic criteria. Although the focus was agrammatism, motor speech skills were also evaluated to determine whether dysfluency arose primarily from apraxia of speech (AOS, instead of, or in addition to, agrammatism. Volumetric MRI analyses provided impartial imaging-supported diagnosis. Results: The majority of cases exhibited neither frank agrammatism nor AOS. Conclusion: There are nfPPA patients with imaging-supported diagnosis and preserved motor speech skills who do not exhibit frank agrammatism, and this may persist beyond the earliest stages of the illness. Because absence of frank agrammatism is a subsidiary diagnostic feature in the logopenic variant of PPA, this result has implications for differentiation of the nonfluent and logopenic variants, and indicates that PPA patients with nonfluent speech in the absence of frank agrammatism or AOS do not necessarily have the logopenic variant.

    2012-11-09

    Frank-ter Haar syndrome is a rare disorder associated with skeletal, cardiac, ocular and craniofacial features including hypertelorism and brachycephaly. The most common underlying genetic defect in Frank-ter Haar syndrome appears to be a mutation in the SH3PXD2B gene on chromosome 5q35.1. Craniosynostosis, or premature fusion of the calvarial sutures, has not previously been described in Frank-ter Haar syndrome. We present a family of three affected siblings born to consanguineous parents with clinical features in keeping with a diagnosis of Frank-ter Haar syndrome. All three siblings have a novel mutation caused by the deletion of exon 13 of the SH3PXD2B gene. Two of the three siblings also have non-scaphocephalic sagittal synostosis associated with raised intracranial pressure. The clinical features of craniosynostosis and raised intracranial pressure in this family with a confirmed diagnosis of Frank-ter Haar syndrome expand the clinical spectrum of the disease. The abnormal cranial proportions in a mouse model of the disease suggests that the association is not coincidental. The possibility of craniosynostosis should be considered in individuals with a suspected diagnosis of Frank-ter Haar syndrome.

    In order to evaluate the importance of higher-order correlations in neural spike count codes, flexible statistical models of dependent multivariate spike counts are required. Copula families, parametric multivariate distributions that represent dependencies, can be applied to construct such models. We introduce the Frank mixture family as a new copula family that has separate parameters for all pairwise and higher-order correlations. In contrast to the Farlie-Gumbel-Morgenstern copula family that shares this property, the Frank mixture copula can model strong correlations. We apply spike count models based on the Frank mixture copula to data generated by a network of leaky integrate-and-fire neurons and compare the goodness of fit to distributions based on the Farlie-Gumbel-Morgenstern family. Finally, we evaluate the importance of using proper single neuron spike count distributions on the Shannon information. We find notable deviations in the entropy that increase with decreasing firing rates. Moreover, we find that the Frank mixture family increases the log likelihood of the fit significantly compared to the Farlie-Gumbel-Morgenstern family. This shows that the Frank mixture copula is a useful tool to assess the importance of higher-order correlations in spike count codes.

  9. Mortimer Frank, Johann Ludwig Choulant, and the history of anatomical illustration.

    Mortimer Frank (1874-1919) was an ophthalmologist in Chicago, Illinois. He published a number of papers on the history of medicine, and was secretary of the Chicago Society of the History of Medicine and editor of their Bulletin. His major contribution to the history of medicine relates to the history of anatomical illustration. The classic book on that subject had been published in 1852 in German by the physician and historian, Johann Ludwig Choulant (1791-1861). However, by Frank's time this text was both out dated and out of print. Frank took on the tremendous project of translating Choulant's German text into English as History and Bibliography of Anatomic Illustration in Its Relation to Anatomic Science and The Graphic Arts. He improved Choulant's text with the results of his and other scholars' research, greatly enlarging the text. Frank supplemented the original book with a biography of Choulant, essays on anatomists not considered in the original text, and an essay on the history of anatomical illustration prior to those authors discussed by Choulant. This book, now referred to as Choulant/Frank, has been reprinted several times, and is still useful as a reference in this field, though some of its research is now dated.

    This study performs a comparison between Dower's inverse transform and Frank lead system for Myocardial Infarction (MI) identification. We have selected a set of relevant features for MI detection from the vectorcardiogram and used the lasso method after that to build a model for the Dower's inverse transform and one for the Frank leads system. Then we analyzed the performance between both models on MI detection. The proposed methods have been tested using PhysioNet PTB database that contains 550 records from which 368 are MIs. Two main conclusions are coming from this study. The first one is that Dower's inverse transform performs equally well than Frank leads in identification of MI patients. The second one is that lead positions have a large influence on the accuracy of MI patient identification.

  11. Frank Close presents his book "Neutrino" and a forthcoming book on Bruno Pontecorvo

    Frank Close's book "Neutrino" is short listed for the Italian Galileo Prize. Frank describes how he was inspired to write about Ray Davis' heroic quest to do what many thought was impossible: detecting neutrinos from the sun. He will also describe how he has, in turn, become fascinated by the life and work of "Mr Neutrino" - Bruno Pontecorvo - and is writing a biography of him.   By choosing to move to the USSR suddenly in 1950, Pontecorvo missed out on getting full credit for several seminal ideas about neutrinos including, possibly, their discovery. Why he went to the USSR so suddenly has been unresolved for 60 years. Frank's book "A Life of Two Halves" may answer this question, in 2014. He will update on progress so far. Wednesday 17 April at 4 p.m. in the Library, 52-1-052 Tea and coffee will be served from 3:30 p.m. Here on Indico.

    Richard von Volkmann (1830–1889), one of the most important surgeons of the 19th century, is regarded as one of the fathers of orthopaedic surgery. He was a contemporary of Langenbeck, Esmarch, Lister, Billroth, Kocher, and Trendelenburg. He was head of the Department of Surgery at the University of Halle, Germany (1867–1889). His popularity attracted doctors and patients from all over the world. He was the lead physician for the German military during two wars. From this experience, he compared the mortality of civilian and war injuries and investigated the general poor hygienic conditions in civilian hospitals. This led him to introduce the “antiseptic technique” to Germany that was developed by Lister. His powers of observation and creativity led him to findings and achievements that to this day bear his name: Volkmann’s contracture and the Hueter-Volkmann law. Additionally, he was a gifted writer; he published not only scientific literature but also books of children’s fairy tales and poems under the pen name of Richard Leander, assuring him a permanent place in the world of literature as well as orthopaedics.

  13. Numerical analysis of stress effects on Frank loop evolution during irradiation in austenitic Fe-Cr-Ni alloy

    Tanigawa, H.; Katoh, Y.; Kohyama, A.

    1995-01-01

    Effects of applied stress on early stages of interstitial type Frank loop evolution were investigated by both numerical calculation and irradiation experiments. The final objective of this research is to propose a comprehensive model of complex stress effects on microstructural evolution under various conditions. In the experimental part of this work, the microstructural analysis revealed that the differences in resolved normal stress caused those in the nucleation rates of Frank loops on {111} crystallographic family planes, and that with increasing external applied stress the total nucleation rate of Frank loops was increased. A numerical calculation was carried out primarily to evaluate the validity of models of stress effects on nucleation processes of Frank loop evolution. The calculation stands on rate equations which describe evolution of point defects, small points defect clusters and Frank loops. The rate equations of Frank loop evolution were formulated for {111} planes, considering effects of resolved normal stress to clustering processes of small point defects and growth processes of Frank loops, separately. The experimental results and the predictions from the numerical calculation qualitatively coincided well with each other. (orig.)

  14. John von Neumann selected letters

    2005-01-01

    John von Neuman was perhaps the most influential mathematician of the twentieth century, especially if his broad influence outside mathematics is included. Not only did he contribute to almost all branches of mathematics and created new fields, but he also changed post-World War II history with his work on the design of computers and with being a sought-after technical advisor to many figures in the U.S. military-political establishment in the 1940s and 1950s. The present volume is the first substantial collection of (previously mainly unpublished) letters written by von Neumann to colleagues, friends, government officials, and others. The letters give us a glimpse of the thinking of John von Neumann about mathematics, physics, computer science, science management, education, consulting, politics, and war. Readers of quite diverse backgrounds will find much of interest in this fascinating first-hand look at one of the towering figures of twentieth century science.

    We study global minimizers of a continuum Landau-De Gennes energy functional for nematic liquid crystals, in three-dimensional domains, subject to uniaxial boundary conditions. We analyze the physically relevant limit of small elastic constant and show that global minimizers converge strongly, in W1,2, to a global minimizer predicted by the Oseen-Frank theory for uniaxial nematic liquid crystals with constant order parameter. Moreover, the convergence is uniform in the interior of the domain, away from the singularities of the limiting Oseen-Frank global minimizer. We obtain results on the rate of convergence of the eigenvalues and the regularity of the eigenvectors of the Landau-De Gennes global minimizer. We also study the interplay between biaxiality and uniaxiality in Landau-De Gennes global energy minimizers and obtain estimates for various related quantities such as the biaxiality parameter and the size of admissible strongly biaxial regions. © Springer-Verlag (2009).

This phenomenon has been discussed informally for decades, perhaps as "classic" ASD; however, there is no unitary "classic" presentation, and classic autism does not seem to correspond to level of functioning. Thus, neither "frank" nor "classic" autism has been delineated or studied as a research construct. To initiate the empirical study of frank ASD, we surveyed 151 clinicians, from a range of disciplines that diagnose ASD, about this phenomenon. Respondents completed a 13-item questionnaire about frank ASD, which was analyzed using a mixed-methods approach. Ninety-seven percentage of respondents were familiar with the phenomenon. Respondents estimated that 40% of the ASD population has a frank presentation. Respondents reported the most highly specific behaviors associated with frank presentations were a general sense of impaired reciprocity, quality of eye contact, atypical vocal prosody, presence of motor mannerisms, and atypical gait or posture. In general, respondents reported detecting frank features rapidly, with the majority forming their impressions within the first ten minutes of interaction or observation. Although unstudied empirically, "frank" presentations of ASD are familiar to diagnosing clinicians, and appear to be based on behaviors both central to ASD diagnostic criteria (e.g., impaired reciprocity), and absent from diagnostic criteria (e.g., atypical gait or posture). We discuss these findings within the context of diagnostic decision-making and behavioral phenotyping of ASD.

    Full Text Available RESUMEN La estructura de la modernidad, en general, está al servicio de una nueva concepción espacial fluida y continua, condensada en torno al concepto de “planta libre”. Sin embargo, la riqueza y complejidad de articulación que adquieren las plantas, no se observa en la sección de los edificios, especialmente si se trata de rascacielos. El principio de crecimiento por superposición de plantas iguales y el carácter utilitario de la estructura en esta tipología, anularon su carácter iconográfico y su integración espacial. Frank Lloyd Wright, de modo natural, desarrolla una estructura para sus escasos rascacielos que integra espacio y forma, superando así tanto la simplificación funcional de la Escuela de Chicago, como el valor iconográfico de las experiencias europeas.SUMMARY In general, the structure of modernity serves a new, fluid and continuous, spatial conception, condensed around the “free floor” concept. However, the wealth and complexity of articulation that these floors acquire are not seen in the section of the buildings, especially in the case of skyscrapers. The principle of growth by superimposition of equal floors and the utilitarian character of the structure in this type of building, nullify the iconographic character of the structure and its spatial integration. Frank Lloyd Wright develops a structure for his few skyscrapers that integrates space and form in a natural way, thus surpassing both the functional simplification of the Chicago School, and the iconographic value of the European experiences.

    Full Text Available The concept of shock apparently emerged in the middle of the 18th century (Whyett as an occurrence observed experimentally after spinal cord transection, and identified as "shock" phenomenon one century later (Hall. The concept was extended (Brown-Séquard and it was suggested that brain lesions caused functional rupture in regions distant from the injured one ("action à distance". The term "diaschisis" (von Monakow, proposed as a new modality of shock, had its concept broadened, underpinned by observations of patients, aiming at distinguishing between symptoms of focal brain lesions and transitory effects they produced, attributable to depression of distant parts of the brain connected to the injured area. Presently, diaschisis is related mainly to cerebrovascular lesions and classified according to the connection fibers involved, as proposed by von Monakow. Depression of metabolism and blood flow in regions anatomically separated, but related by connections with the lesion, allows observing diaschisis with neuroimaging.

    Several studies have associated the earlobe crease sign, discovered by Sanders T. Frank in 1973, with cardiovascular pathology, yet very few studies have focused on the antiquity of this trait, with the most ancient one thought to date back to the Roman Emperor Hadrian (76-138CE). This article presents two more cases from the Italian Renaissance in the works of the artist Andrea Mantegna (1431-1506) and examines them in a multidisciplinary fashion.

  2. The core structure of a Frank dislocation in Ni3(Al,Nb)

    1991-01-01

    This paper reports on the core structures of dislocations in L1 2 crystals, in view of understanding the anomalous yield behavior of strength with increasing temperature. Theoretical approaches have been proposed for explaining the dissociations of these dislocations, and experimental evidences have been reported for such dissociations using either the weak beam technique or more recently the HRTEM (High Resolution Transmission Electron Microscopy) technique. Recent HRTEM results show that for Ni 3 A1 the partial dislocations 1/2 left-angle 110 right-angle which limit an APB (Antiphase Boundary) lying on (001) are only split over 0.1 - 0.3 nm along (111) planes, producing very high energy CSF's (Complex Stacking Faults) which limit an SISF (superlattice Intrinsic Stacking Fault) extended on a (111) plane. Concerning the 1/2 left-angle 111 right-angle Frank dislocation, which limits an SESF (Superlattice Extrinsic Stacking Fault), there are no reported results yet. Let us note, however, that for aluminum HRTEM images of Frank dislocation loops have been studied. This lack of information in the L1 2 crystals motivated the present HRTEM study

    Mutations in the SH3PXD2B gene coding for the Tks4 protein are responsible for the autosomal recessive Frank-ter Haar syndrome. Tks4, a substrate of Src tyrosine kinase, is implicated in the regulation of podosome formation. Here, we report a novel role for Tks4 in the EGF signaling pathway. In EGF-treated cells, Tks4 is tyrosine-phosphorylated and associated with the activated EGF receptor. This association is not direct but requires the presence of Src tyrosine kinase. In addition, treatment of cells with LY294002, an inhibitor of PI 3-kinase, or mutations of the PX domain reduces tyrosine phosphorylation and membrane translocation of Tks4. Furthermore, a PX domain mutant (R43W) Tks4 carrying a reported point mutation in a Frank-ter Haar syndrome patient showed aberrant intracellular expression and reduced phosphoinositide binding. Finally, silencing of Tks4 was shown to markedly inhibit HeLa cell migration in a Boyden chamber assay in response to EGF or serum. Our results therefore reveal a new function for Tks4 in the regulation of growth factor-dependent cell migration.

    Full Text Available Abstract A germline mutation in the Von-Hippel Lindau (VHL gene predisposes carriers to development of abundantly vascularised tumours in the retina, cerebellum, spine, kidney, adrenal gland and pancreas. Most VHL patients die from the consequences of cerebellar haemangioblastoma or renal cell carcinoma. The VHL gene is a tumour suppressor gene and is involved in angiogenesis by regulation of the activity of hypoxia-inducible factor 1-α (HIF1-α. Clinical diagnosis of VHL can be confirmed by molecular genetic analysis of the VHL gene, which is informative in virtually all VHL families. A patient with (suspicion for VHL is an indication for genetic counselling and periodical examination.

  8. Frank and Fearless: Supporting Academic Career Progression for Women in an Australian Program

    Directory of Open Access Journals (Sweden)

    2018-02-01

    Full Text Available The underrepresentation of women in senior positions continues to be a major challenge in higher education and most other industries. In Australia, the career trajectory for academic women stalls at a lower level than that of their male counterparts. Concern about this situation in one Australian university led to the design and delivery of a career progression program to support women’s advancement from senior lecturer to associate professor. This study details the main features of the program, designed to facilitate women’s transition from being leading academics to academic leaders through a focus on leadership and career progression. We report the participants’ perceptions of its value based on survey data. We conclude that leadership development is difficult work and requires a supportive environment where risk-taking is encouraged, where frank and fearless feedback is provided, and where the individual is required to examine assumptions and biases and to assume a leadership identity.

    An increasing number of authors agree in that the maximum entropy principle (MaxEnt) is essential for the understanding of macroecological patterns. However, there are subtle but crucial differences among the approaches by several of these authors. This poses a major obstacle for anyone interested in applying the methodology of MaxEnt in this context. In a recent publication, Frank (2011) gives some arguments why his own approach would represent an improvement as compared to the earlier paper by Pueyo et al. (2007) and also to the views by Edwin T. Jaynes, who first formulated MaxEnt in the context of statistical physics. Here I show that his criticisms are flawed and that there are fundamental reasons to prefer the original approach.

    2017-10-01

    Full Text Available Frank Lloyd Wright is considered one of the most influential architects of modern architecture due to the spatial and aesthetic qualities of his work. However, the importance of Wright’s construction and environmental solutions has been usually overlooked. In order to evaluate these qualities, the first house that Wright designed for the Jacobs family (Wisconsin, USA, 1937 has been analyzed. This well-known building has been much studied, and its architectural value much celebrated, but without analysing the advantages of the bioclimatic principles over interior environment. But how can the influence of this bioclimatic architecture be measured in terms of thermal comfort? Does the selected orientation improve interior comfort? And what about the natural ventilation or the deep overhangs? In order to assess this, a digital model for energy simulation has been built using Revit and Design Builder.

  11. An inevitable end? The collapse of the Lombard kingdom facing the Franks and the papacy

    Directory of Open Access Journals (Sweden)

    Stefano Gasparri

    2016-09-01

    Full Text Available According to the Italian historiography, from Alessandro Manzoni (1822 to the two major Italian historians who studied the Lombards at the middle of the twentieth century, Gian Piero Bognetti and Ottorino Bertolini, the Lombards remained always separated from the Roman population, of which the pope was the natural leader; the Lombards, too, became very late Catholics, in time, though, to experience the "drama" of having to fight against the pope, whose supreme spiritual authority the Lombards themselves at that point recognized. Consequently, the fall of the independent kingdom by the hands of the Franks would be logical and inevitable. This is an old and outdated position: the end of the independent Lombard kingdom wasn’t inevitable. At the time of the Frankish conquest, the kingdom was politically solid inward, in economic growth and very dynamic outward. During the reigns of Liutprand, Ratchis and Aistulf (712-757, the kingdom exercised its hegemony over the whole Italy. In this period no strong elements of internal weakness emerged. Therefore, the defeat of 774 was substantially caused by external factors, ie the alliance between the Franks and the papacy. However, the attitude of the popes against the Lombard kingdom was not always hostile. Things changed only with Stephen II, because of two simultaneous events occurring in 751: the royal anointing of Pepin in the Frankish kingdom and the conquest of the Exarchate by Aistulf. Italian political balance broke and caused the decisive rapprochement between Rome and the Franks. But there were still many uncertainties, as proved, for example, by Charlemagne’s marriage with a daughter of Desiderius. Carloman’s death in 771 and, the following year, the election of the new pope Adrian I caused the repudiation of the Lombard bride by Charlemagne, his descent into Italy in 773, and the capture of Pavia the year after: Desiderius was exiled in France and Charlemagne became rex Langobardorum.

    2018-03-01

    We study the relationship between Onsager's molecular theory, which involves the effects of nonlocal molecular interactions and the Oseen-Frank theory for nematic liquid crystals. Under the molecular setting, we prove the existence of global minimizers for the generalized Onsager's free energy, subject to a nonlocal boundary condition which prescribes the second moment of the number density function near the boundary. Moreover, when the re-scaled interaction distance tends to zero, the global minimizers will converge to a uniaxial distribution predicted by a minimizing harmonic map. This is achieved through the investigations of the compactness property and the boundary behaviors of the corresponding second moments. A similar result is established for critical points of the free energy that fulfill a natural energy bound.

    2009-07-01

    Full Text Available The purpose of this research was to investigate how stories can be a learning tool to help teachers make sense of and learn from their own stories of teaching. The participants in this study were teachers enrolled in a graduate level course.  Frank McCourt’s novel, Teacher Man acted as a stimulus, springboard and guide for class discussions and for teachers writing their own story of teaching. My mode of inquiry included collecting the teachers’ written responses to class readings, noting their oral responses during class discussions, asking them to complete a short questionnaire, and following up with a taped focus group three months after the completion of the course. By reading, hearing and discussing the stories of others, teachers came to recognize the power of stories.  Writing their own stories helped them to understand their own practice better.

    Full Text Available This article assesses the benefits and costs of key provisions of the Dodd-Frank Act that strengthened regulation following the financial crisis. The provisions are placed into five groupings: clear wins, clear losses, costly tradeoffs, unfinished business, and too soon to tell. Clear wins include higher prudential standards, including for capital; the single-point-of-entry resolution authority; creation of the Consumer Financial Protection Bureau; and greater transparency and oversight of derivatives. Clear losses are restrictions on Federal Reserve emergency lending authority and forcing the Federal Deposit Insurance Corporation to obtain permission from Congress before providing temporary liquidity guarantees. Costly tradeoffs are the Volcker Rule and the Lincoln Amendment. Unfinished business includes regulatory consolidation and more independence for the Financial Stability Oversight Council and the Office of Financial Research. Too soon to tell are requirements and standards for leverage ratios, capital buffers, stress testing, and liquidity requirements.

  17. Modern housing design: prefabricated and modular design in Frank Lloyd Wright's architecture

    Directory of Open Access Journals (Sweden)

    Ana Tagliari

    2011-12-01

    Full Text Available This paper investigates the residential architecture of Frank Lloyd Wright, especially the designs which were conceived from an idea of prefabricated, modular, low-cost, and high-scale construction. Wright's organic designs originated from a material-based grid, which at the same time organized and provided freedom to create spaces and forms. This study reviews Wright's work, from his first Midwest designs that relied on brick, through an intermediary phase in California when he made intense use of concrete blocks, until his last phase, the usonian houses, which featured wood paneling. During his early career, the concept and the methodology of Wright's ideas greatly contributed to a better understanding of his architecture, his apprentices and his followers. The economy and rationalization found in the projects reviewed are of great importance as the analysis of historical proposals helps us understand the topic in question.

    Full Text Available Frank O’Hara’s 1957 poetry collection, Meditations in an Emergency, features in Season Two of Mad Men (2008 as a talismanic phrase and object. Pressed into service as Matthew Weiner’s valentine to his returning viewers, the circulation and citation of the book across the season, through different diegetic and extradiegetic levels, aligns poetry, advertising and quality serial television drama as textual modes intent, above all, on creating attachment through feeling. O’Hara’s book is a crucial link in a series of metonymic relays, chain effects and affects, which underwrite Mad Men’s citational poetics to assert its own cultural authority, and the mediating power of television.

  19. Some considerations in the splitting of interstitial frank loops formed by irradiation

    Seshan, K.; Grilhe, J.; Washburn, J.

    1975-05-01

    The splitting of interstitial loops formed by irradiation is considered in detail. It is shown that they may split to form obtuse--angled single shear faults on the intersecting (111) planes. A detailed description of the splitting is given in which the interstitial Frank loop is viewed as being made up of perfect dislocation loop and two shears. The detailed description is then considered in the context of the formation of complex loops as are observed in quenching and irradiation studies. Experimentally observed geometries are explained viz, triangular loops within hexagonal ones etc. The nucleation of a DC' loop in complex interstitial loop formation is shown to be feasible. DC' has the magnitude of a perfect dislocation loop and encloses an intrinsic shear

    The von Meyenburg complex (VMC) describes bile duct hamartomas and presents a rare, benign incidental finding in liver imaging. We report on a 61-year-old man, who was referred for a follow up study 14 years after remission of Hodgkin's disease. Computed tomography (CT) revealed multiple hypodense lesions throughout the liver, primary suggesting recurrent Hodgkin's disease. Previous CT-examinations, which were obtained at a later date, showed those lesions in identical distribution and morphology over the years, leading to diagnosis of multiple bile duct hamartomas (VMC). Making imaging-based diagnosis of VMC including ultrasound, CT and magnetic resonance imaging is a challenging task for the radiologist. Based on literature research findings, the impact of different modalities in the diagnostic work-up of VMC is discussed. (orig.)

  13. Titanisierung von Implantatoberflächen

    Science.gov (United States)

    Zimmermann, Hanngörg; Heinlein, Markus; Guldner, Norbert W.

    Titan gilt seit Jahrzehnten als einer der wichtigsten Implantatwerkstoffe in der Medizin. Neben den guten mechanischen Eigenschaften (Leichtigkeit, hohe Festigkeit etc.), besitzen Titanimplantate vor allem eine hervorragende Körperverträglichkeit, so dass die Implantate optimal in den humanen Organismus integriert werden [1]. Ist jedoch aufgrund der Anforderungen an das Implantat eine hohe Flexibilität und/ oder Elastizität gefragt, so scheidet der Werkstoff Titan aufgrund seiner spröden und unflexiblen Materialeigenschaften aus. Die Folge ist der Einsatz von Implantatmaterialien, sowohl künstlichen als auch biologischen Ursprungs, welche nicht selten eine unzureichende Biokompatibilität aufweisen und somit zu Fremdköper- und immunologischen Reaktionen und Einkapselung des Implantates führen können. Die Erhöhung der Körperverträglichkeit, eine Adaption an das biologische Umfeld und eine hohe Biokompatibilität sind demzufolge die wichtigsten Eigenschaften bei der bedarfsgerechten Herstellung von Implantaten und Implantatoberflächen. Zur Gestaltung von innovativen, biokompatiblen Oberflächen stehen unterschiedliche technische Lösungsansätze zur Verfügung. Zum einen besteht die Möglichkeit, geeignete Oberflächeneigenschaften aus dem Grundmaterial selbst zu optimieren. Dies geschieht unter anderem durch Modifikation der Werkstoffoberflächen in Form von Texturierungen und Oberflächenrauhigkeiten. Zum anderen können die Oberflächeneigenschaften unabhängig von denen des Trägermaterials gestaltet werden. Durch Funktionalisierung der Oberflächen mit geeigneten Beschichtungen oder der Zugabe von Medikamenten (Drug Eluting) werden die Kunststoffimplantate dahingehend verändert, dass eine Steigerung der Körperakzeptanz erreicht wird. Die Titanbeschichtung von Implantatoberflächen kombiniert die positiven Materialeigenschaften von Titan und Polymer.

    Effects of applied stress on early stages of interstitial type Frank loop evolution were investigated by both numerical calculation and irradiation experiments. The final objective of this research is to propose a comprehensive model of complex stress effects on microstructural evolution under various conditions. In the experimental part of this work, the microstructural analysis revealed that the differences in resolved normal stress caused those in the nucleation rates of Frank loops on {111} crystallographic family planes, and that with increasing external applied stress the total nucleation rate of Frank loops was increased. A numerical calculation was carried out primarily to evaluate the validity of models of stress effects on nucleation processes of Frank loop evolution. The calculation stands on rate equuations which describe evolution of point defects, small points defect clusters and Frank loops. The rate equations of Frank loop evolution were formulated for {111} planes, considering effects of resolved normal stress to clustering processes of small point defects and growth processes of Frank loops, separately. The experimental results and the predictions from the numerical calculation qualitatively coincided well with each other.

  20. War, Medicine, and Cultural Diplomacy in the Americas: Frank Wilson and Brazilian cardiology.

    Kropf, Simone P; Howell, Joel D

    2017-10-01

    American cultural diplomacy played a key role in the institutionalization of Brazilian cardiology. In 1942, Frank Wilson, an internationally recognized pioneer in electrocardiography, made an extended wartime visit to Rio de Janeiro and São Paulo. The visit was sponsored by the United States Department of State as part of Roosevelt's Good Neighbor Policy and brought Wilson together with a group of physicians who would establish the specialty of cardiology in Brazil. This US cultural and diplomatic initiative strengthened an academic network that was already evolving and would eventually prove to be of benefit to both sides. Latin American physicians began in the 1920s to visit Wilson's laboratory at the University of Michigan, where they established the relationships on which Wilson would build. While affiliation with the "Wilson school" advanced the cause of Brazilian cardiologists who sought to establish themselves as specialists, cooperation with Latin American physicians benefitted Wilson in his pursuit of wider recognition for his innovations in the use of electrocardiography (ECG). Wilson's identity as a scientific ambassador to Latin America helped in legitimating his approach to the clinical application of the ECG. A close examination of Wilson's relationship to Brazilian cardiology demonstrates the role played by science and medicine as a part of wartime cultural diplomacy, as well as the dynamics of the transnational circulation of scientific knowledge and practices. © The Author 2017.

  1. Risk, uncertainty and prophet: The psychological insights of Frank H. Knight

    Directory of Open Access Journals (Sweden)

    2010-10-01

    Full Text Available Economist Frank H. Knight (1885--1972 is commonly credited with defining the distinction between decisions under ``risk'' (known chance and decisions under ``uncertainty'' (unmeasurable probability in his 1921 book Risk, Uncertainty and Profit. A closer reading of Knight (1921 reveals a host of psychological insights beyond this risk-uncertainty distinction, many of which foreshadow revolutionary advances in psychological decision theory from the latter half of the 20th century. Knight's description of economic decision making shared much with Simon's (1955, 1956 notion of bounded rationality, whereby choice behavior is regulated by cognitive and environmental constraints. Knight described features of risky choice that were to become key components of prospect theory (Kahneman and Tversky, 1979: the reference dependent valuation of outcomes, and the non-linear weighting of probabilities. Knight also discussed several biases in human decision making, and pointed to two systems of reasoning: one quick, intuitive but error prone, and a slower, more deliberate, rule-based system. A discussion of Knight's potential contribution to psychological decision theory emphasises the importance of a historical perspective on theory development, and the potential value of sourcing ideas from other disciplines or from earlier periods of time.

    In the many years since it was first proposed, the Burton- Cabrera-Frank (BCF) model of step-flow has been experimentally established as one of the cornerstones of surface physics. However, many questions remain regarding the underlying physical processes and theoretical assumptions that give rise to the BCF theory. In this work, we formally derive the BCF theory from an atomistic, kinetic Monte Carlo model of the surface in 1 +1 dimensions with one step. Our analysis (i) shows how the BCF theory describes a surface with a low density of adsorbed atoms, and (ii) establishes a set of near-equilibrium conditions ensuring that the theory remains valid for all times.

    Full Text Available Conceived in the late thirties as “bold humanist response to Depression-era fears of runaway scientific advance and soulless industrialism” (Morrison 2012, 6, the superhero has flourished as one of the most resilient archetypes of American popular culture. This essay analyses the literary and cultural contaminations that have engendered an unprecedented revision of the paradigm since the 1980s. In particular, it will take into account three graphic novels by American cartoonist Frank Miller (1957 - , one of leading figures of the mainstream comics renaissance, whose ideas have indelibly influenced the artistic development of both medium and genre. The Dark Knight Returns (1986, The Dark Knight Strikes Again (2002 and Holy Terror (2011 constitute an ideal Batman trilogy that charts the character’s evolution as political counterpoint to the perceived crisis of American identity. In this regard, Reaganism and 9/11 are polarized as historical discontinuities triggering the need for a new kind of a criminal (superhero. It will be in fact demonstrated how the novels hybridise the latent generic links to hardboiled pulp novels (R. Chandler, D.

  4. The Anne Frank Haven: A case of an alternative educational program in an integrative Kibbutz setting

    1992-01-01

    The essential features of the programme of the Anne Frank Haven are the complete integration of children from low SES and different cultural backgrounds with Kibbutz children; a holistic approach to education; and the involvement of the whole community in an "open" residential school. After 33 years, it is argued that the experiment has proved successful in absorbing city-born youth in the Kibbutz, enabling at-risk populations to reach significant academic achievements, and ensuring their continued participation in the dominant culture. The basic integration model consists of "layers" of concentric circles, in dynamic interaction. The innermost circle is the class, the learning community. The Kibbutz community and the foster parents form a supportive, enveloping circle, which enables students to become part of the outer community and to intervene in it. A kind of meta-environment, the inter-Kibbutz partnership and the Israeli educational system, influence the program through decision making and guidance. Some of the principles of the Haven — integration, community involvement, a year's induction for all new students, and open residential settings — could be useful for cultures and societies outside the Kibbutz. The real "secret" of success of an alternative educational program is the dedicated, motivated and highly trained staff.

    Full Text Available Whether in political propaganda or in creative the myths of ancient Greece have long attracted scholars, writers and audiences from Ireland. Over the past forty years, a wealth of adaptations of plays by Sophocles and Euripides have been produced, which bring back to life ancient tales of heroes and heroines, in settings at times distinctively local and contemporary, at times deliberately universal. Field Day’s contributions represent a typical instance of the former approach to the classics, while other Irish playwrights have used Greek myths to reflect upon questions that are not exclusively Irish. Their plays may have an Irish echo, and some are even set in Ireland, but their main preoccupation lies beyond geographical borders. Frank McGuinness belongs to this second group of playwrights. To date, he has reworked and staged five Greek plays with great audience and critical acclaim. This paper locates his translations of Sophocles and Euripides within the tradition of classical tragedy use in Ireland at the crossroads between the local and the global and at the search of what he calls ‘the root of all evil’ with special attention to his Oedipus (2008 and Helen (2009.

    Highlights: → Testing of Frank's hypothesis for Centripetal Packing (CP) has been proposed. → It is shown that CP is an idealized model for Monatomic Supercooled Liquid (MSL). → The CP is fit for comparing with studies on MSL in a containerless environment. → We measure local orders in CP by HA and BOO methods for the first time. → It is shown that icosahedral order is greater in CP than MSL and reasons explored. - Abstract: It is well-known that metallic liquids can exist below their equilibrium melting temperature for a considerable time. To explain this, Frank proposed that icosahedral ordering, incompatible with crystalline long-range order, is prevalent in the atomic structure of these liquids, stabilizing them and enabling them to be supercooled. Some studies of the atomic structures of metallic liquids using Beam-line Electrostatic Levitation (BESL; containerless melting), and other techniques, support this hypothesis . Here we examine Frank's hypothesis in a system of macroscopic, monodisperse deformable spheres obtained by containerless packing under the influence of centripetal force. The local structure of this packing is analyzed and compared with atomic ensembles of liquid transition metals obtained by containerless melting using the BESL method.

  13. Victorian Imag(ining of the Pagan Pyre: Frank Dicksee's 'Funeral of a Viking'

    Directory of Open Access Journals (Sweden)

    Nancy Rose Marshall

    2017-12-01

    Full Text Available Victorians drew on imagery of Druid and Viking funeral pyres as a way of exploring alternative narratives of death and burial, generating a collective attention to what happened to a body after death. I set Frank Dicksee’s oil painting, 'Funeral of a Viking' (1893, against the background of the emergent cremation movement and accounts of the neo-Druid William Price, a proponent for the legalization of cremation in the 1880s, in order to glimpse the work performed by the visualization of the ritualized burning of human beings in the pagan past. Fire produces metamorphosis in the objects it encounters, and Dicksee’s portrayal underscores the notion of a clearly delineated human body transforming into amorphous flame. Moreover, the Viking dissolves into pigment itself, mere aesthetic effect taking the place of a recognizable figure. In fictional accounts such as Paul Du Chaillu’s novel 'Ivar the Viking '(1893, the pyre as a narrative tool similarly forced attention to the body as dematerializing thing and to the language articulating this dissipation. I suggest that the Victorian fascination with pagan fire-death allowed for alternate visions of form–matter relationships that in turn might produce new aesthetic possibilities. As the Christian world insisted on the resurrection of the body in a way that clung fiercely to tangibility and bounded form even in the face of belief in the immortality of the saved soul, the modern moment might be seen, in contrast, as characterized by an embrace of an aesthetic of dissolving form or formlessness.

    Full Text Available This paper develops a means of more easily and less invasively estimating ventricular dead space volume (Vd, an important, but difficult to measure physiological parameter. Vd represents a subject and condition dependent portion of measured ventricular volume that is not actively participating in ventricular function. It is employed in models based on the time varying elastance concept, which see widespread use in haemodynamic studies, and may have direct diagnostic use. The proposed method involves linear extrapolation of a Frank-Starling curve (stroke volume vs end-diastolic volume and its end-systolic equivalent (stroke volume vs end-systolic volume, developed across normal clinical procedures such as recruitment manoeuvres, to their point of intersection with the y-axis (where stroke volume is 0 to determine Vd. To demonstrate the broad applicability of the method, it was validated across a cohort of six sedated and anaesthetised male Pietrain pigs, encompassing a variety of cardiac states from healthy baseline behaviour to circulatory failure due to septic shock induced by endotoxin infusion. Linear extrapolation of the curves was supported by strong linear correlation coefficients of R = 0.78 and R = 0.80 average for pre- and post- endotoxin infusion respectively, as well as good agreement between the two linearly extrapolated y-intercepts (Vd for each subject (no more than 7.8% variation. Method validity was further supported by the physiologically reasonable Vd values produced, equivalent to 44.3-53.1% and 49.3-82.6% of baseline end-systolic volume before and after endotoxin infusion respectively. This method has the potential to allow Vd to be estimated without a particularly demanding, specialised protocol in an experimental environment. Further, due to the common use of both mechanical ventilation and recruitment manoeuvres in intensive care, this method, subject to the availability of multi-beat echocardiography, has the potential to

  15. Popular Science and Apocalyptic Narrative in Frank Schätzing’s The Swarm

    Directory of Open Access Journals (Sweden)

    2012-01-01

    Full Text Available This paper analyses the use of the rhetoric of the Apocalypse and the concept of nature's revenge in Frank Schätzing's eco-thriller The Swarm. Ecocritical research has identified these narrative patterns as characteristic of contemporary environmental literature. In The Swarm, the apocalyptical rhetoric fulfils the double function of providing thrill and pleasure to the readers and warning them about imminent environmental peril, thereby combining conventions from the two genres of eco-thriller and science fiction. Contrasting reviews have described the novel as either enlightening or pseudo-religious. This ambivalence is the effect of various strategies employed to popularise scientific knowledge in the novel. The narrative embraces various scientific fields, for example the depiction of a network in contrast to swarm theory. The key conflict in the story embodies conflicting concepts of nature - anthropocentric vs. eco-systemic - which are represented by two contrasting groups of characters: one aiming to extinguish the alien superorganism that attacks the human race, the other aspiring to integrate the alien organism into the human world and propagating a holistic view of the Earth. The concepts of a 'tragic' and a 'comical apocalypse' correspond to the double closure which first features a show-down, the annihilation of the 'bad' characters, and then, in the epilogue, a warning message delivered by a 'good' character which confirms - in contrast to, for example, Michael Crichton's State of Fear - the ongoing environmental crisis. Although the epilogue extensively appeals to the human ability to rethink attitudes towards nature, the novel's support for environmental concerns is limited, not only because this message remains rather abstract but also because the vision of a reconciled, pseudo-religious ecosystem as a holistic superorganism has a highly ambivalent meaning for humanity.

Die Studierenden beurteilen den Einsatz von Weblogs jedoch unterschiedlich. Dabei ist wenig bekannt, welchen Einfluss die Vergabe und das Erhalten von Peerfeedback auf den Beurteilungsprozess von praktikumsbegleitenden Weblogs sowie auf den Umfang von Blogpostings haben. Im folgenden Beitrag wird dieser Frage mittels einer Befragung von 74 angehenden Lehrpersonen nachgegangen, die praktikumsbegleitende Weblogs mit oder ohne Peerfeedback nutzten, um über herausfordernde Ereignisse im Praktikum zu reflektieren. Die Ergebnisse zeigen, dass Studierende, die Peerfeedback erhielten und andere Blogbeiträge kommentierten, den Weblogeinsatz nützlicher einschätzen sowie eine höhere Motivation und positivere Einstellung gegenüber den Einsatz von Weblogs aufweisen als Studierende, die ohne Peerfeedback bloggen. Keinen Einfluss hat Peerfeedback auf den Umfang der Blogbeiträge und auf die dafür aufgewendete Zeit.

  4. When Deriving the Spatial QRS-T Angle from the 12-lead ECG, which Transform is More Frank: Regression or Inverse Dower?

    Science.gov (United States)

    Schlegel, Todd T.; Cortez, Daniel

    2010-01-01

    Our primary objective was to ascertain which commonly used 12-to-Frank-lead transformation yields spatial QRS-T angle values closest to those obtained from simultaneously collected true Frank-lead recordings. Simultaneous 12-lead and Frank XYZ-lead recordings were analyzed for 100 post-myocardial infarction patients and 50 controls. Relative agreement, with true Frank-lead results, of 12-to-Frank-lead transformed results for the spatial QRS-T angle using Kors regression versus inverse Dower was assessed via ANOVA, Lin s concordance and Bland-Altman plots. Spatial QRS-T angles from the true Frank leads were not significantly different than those derived from the Kors regression-related transformation but were significantly smaller than those derived from the inverse Dower-related transformation (P less than 0.001). Independent of method, spatial mean QRS-T angles were also always significantly larger than spatial maximum (peaks) QRS-T angles. Spatial QRS-T angles are best approximated by regression-related transforms. Spatial mean and spatial peaks QRS-T angles should also not be used interchangeably.

  6. Some aspects of Adolf von Harnack’s criticism on Orthodox tradition

    2013-01-01

    Full Text Available The aim of this article is to present the critique that Adolf von Harnack (1851–1930 formulated on the Orthodox tradition in his famous book Das Wesen des Christentums, as well as to comment on its affirmations in the context of his time and way of thinking and to try and find explanations for his criticism. The article concludes that although Harnack’s critique on the Orthodox tradition may have presented negative perception of Orthodoxy, particularly amongst Protestants and many Orthodox theologians who were furious after reading his paper, yet, his critical affirmations also have constructive aspects. However, some of the conclusions of Harnack’s criticism are genuinely rejected by the Orthodox theologians and are no longer sustainable. As a theologian, Harnack cannot be considered an opponent of the modern ecumenical movement, but rather as one of its pioneers. Harnack could be included in the category of frank ecumenists who prefer to express in a critical, but constructive way that which he believes about his own Christian tradition, as well as other Christian traditions.

    2009-01-01

    Fractal geometry is used in diverse research areas, being an useful tool in describing the mechanical behaviour of natural and man-made structures. In this paper, the structural behaviour of a von Koch cantilever beam is analyzed in the small deformations regime. Analytical recursive formulae for the strain energy scaling are derived, which have been found in good agreement with numerical simulations. Energy considerations suggest a peculiar scaling for the beam rigidity in order to prevent compliance divergence. The results are then extended to evaluate the stiffness matrix of a von Koch beam.

Eigentliche Unterrichtssoftware, die speziell für den Unterricht hergestellt und auf Lehrmittel und Curriculum abgestimmt ist, gibt es kaum. Im Projekt «Lernsoftware Evaluation» des Pestalozzianums Zürich ermitteln Lehrpersonen die Qualität von Bildungssoftware, indem sie diese im Unterricht einsetzen und anhand eines Kriterienrasters beurteilen. Eine Analyse der in der Evaluation generierten Daten belegt die Problematik des Anspruchs einer objektiven Qualitätsbeurteilung. Es werden die Probleme bei der Anwendung von Kriterienraster und Beurteilungsmodus aufgezeigt und ermittelt, worin die subjektiven Qualitätsmassstäbe der Evaluierenden begründet sind. Diese Ausführungen sind Teil eines Forschungsprojekts für die Weiterentwicklung einer theoretisch fundierten, aber dennoch praxisnahen Evaluation von Bildungssoftware.

    Full Text Available Zusammenfassung Der kurze, nicht vollständig erhaltene Briefwechsel zwischen Alexander von Humboldt und Karl Ernst von Baer behandelt sehr verschiedene Themen: Politik, Kriegsgefahr, den Wissenschaftsbetrieb, Auszeichnungen und Tagungen, Embryologie und Cholera. Gemeinsam mit Briefen und Reden ergibt sich dabei ein differenziertes Bild der Beurteilung der beiden Wissenschaftler durch den jeweils anderen. Während Baer sich als Bewunderer Humboldts erweist, erscheint umgekehrt Humboldts Einschätzung Baers als ambivalent. Abstract The short, not completely preserved correspondence between Alexander von Humboldt and Karl Ernst von Baer deals with a wide range of subjects: politics and the danger of war, academic activities, scientific awards and conferences, aspects of embryology and the cholera. Letters to third persons and speeches, together with the correspondence between Humboldt and Baer show a differentiated pattern of mutual appraisal: While Baer always remained an admirer of the elder naturalist, Humboldt’s estimation was characterized by ambivalence.

    Gleichgewichtsmodelle ein- und zweikomponentiger Satellitengalaxien werden erzeugt und die Gezeiteneinwirkungen der als starres äußeres Potential angenommenen Milchstraße auf sie betrachtet. Eine erste Reihe von Simulationen mit anfänglich kugelsymmetrischen einkomponentigen Satelliten zeigt, daß sich nach elliptischer Deformation ein Balken und Schweife ungleicher Länge ausbilden, deren Aussehen sich periodisch ändert. Mithilfe von Vergleichssimulationen wurden folgende Phänomene am Satelliten entdeckt: (1) Hochdichtebereiche in den Schweifen, (2) Niedrigdichtebereiche um den Kern bzw. Balken und (3) ein oft verdeckter Balken. Analysiert wird das Erscheinungsbild in Zeitabhängigkeit. Die Teilchen gehen dem Kern über den Balken verloren und bewegen sich entlang gewisser stets gleich aussehender charakteristischer Strukturen in die Schweife. Nach einer Herleitung allgemeiner Größen des mehrkomponentigen Kingprofils werden drei stabile Standardmodelle zweikomponentiger Satellitengalaxien mit Massenverhältnis 1:10 (baryonische zu dunkle Materie) und unterschiedlicher Verteilung der dunklen und sichtbaren Materie gefunden. Ohne die Allgemeinheit der Ergebnisse zu beeinträchtigen, wurde dabei die Große Magellanische Wolke als Grundlage der Modelle genommen. Nach geeigneter Wahl der Bahn, zu der der Gezeitenradius des verwendeten dreikomponentigen Milchstraßenpotentials sowohl analytisch als auch numerisch berechnet wird, werden Simulationen der Modelle analysiert. Hauptaugenmerk ist das unterschiedliche Verhalten der Komponenten. Hauptergebnisse: (1) Es ist möglich, große Anteile dunkler, jedoch nur geringe sichtbarer Materie abzulösen. Dunkle und sichtbare Materie können unterschiedliche morphologische Strukturen bilden. (2) Je nach Konzentration der Komponenten ist die Eigengravitation der Teilchen mehr oder weniger für das Aussehen bestimmend. (3) Die Kernauflösung des Satelliten findet im Perigalaktikum (PG), sein Zerfall aber erst im

    A Murray–von Neumann algebra is the algebra of operators affiliated with a finite von Neumann algebra. In this article, we first present a brief introduction to the theory of derivations of operator algebras from both the physical and mathematical points of view. We then describe our recent work on derivations of Murray–von Neumann algebras. We show that the “extended derivations” of a Murray–von Neumann algebra, those that map the associated finite von Neumann algebra into itself, are inner. In particular, we prove that the only derivation that maps a Murray–von Neumann algebra associated with a factor of type II1 into that factor is 0. Those results are extensions of Singer’s seminal result answering a question of Kaplansky, as applied to von Neumann algebras: The algebra may be noncommutative and may even contain unbounded elements.

    Although heavy ion irradiation is a good tool to simulate neutron irradiation-induced damages in light water reactor, it produces inhomogeneous defect distribution. Such difference in defect distribution brings difficulty in comparing the microstructure evolution and mechanical degradation between neutron and heavy ion irradiation, and thus needs to be understood. Stainless steel is the typical structural material used in reactor core, and could be taken as an example to study the inhomogeneous defect depth distribution in heavy ion irradiation and its influence on the tested irradiation hardening by nano-indentation. In this work, solution annealed stainless steel model alloys are irradiated by 3 MeV Fe{sup 2+} ions at 400 °C to 3 dpa to produce Frank loops that are mainly interstitial in nature. The silicon content of the model alloys is also tuned to change point defect diffusion, so that the loop depth distribution influenced by diffusion along the irradiation beam direction could be discussed. Results show that in low Si (0% Si) and base Si (0.42% Si) samples the depth distribution of Frank loop density quite well matches the dpa profile calculated by the SRIM code, but in high Si sample (0.95% Si), the loop number density in the near-surface region is very low. One possible explanation could be Si’s role in enhancing the effective vacancy diffusivity, promoting recombination and thus suppressing interstitial Frank loops, especially in the near-surface region, where vacancies concentrate. By considering the loop depth distribution, the tested irradiation hardening is successfully explained by the Orowan model. A hardening coefficient of around 0.30 is obtained for all the three samples. This attempt in interpreting hardening results may make it easier to compare the mechanical degradation between different irradiation experiments.

    Full Text Available We have studied beating mouse cardiac syncytia in vitro in order to assess the inotropic, ergotropic, and chronotropic effects of both increasing and decreasing hydrostatic pressures. In particular, we have performed an image processing analysis to evaluate the kinematics and the dynamics of those pressure-loaded beating syncytia starting from the video registration of their contraction movement. By this analysis, we have verified the Frank-Starling law of the heart in in vitro beating cardiac syncytia and we have obtained their geometrical-functional classification.

    In this article we propose the translation of William Franke’s paper On the Poetic Truth that is Higher than History: Porphyry and the Philosophical Criticism of Literature, in which the American scholar presents the hermeneutic method of the ancient commentators of Homer, with particular reference to the critic practice applied by the Neoplatonic Porphyry in his De Antro Nympharum. With this treatment Franke proposes and hopes for the return to an interpretive method, called philosophical or speculative, also for contemporary criticism.

    Full Text Available Mechanoelectric feedback (MEF is the process by which mechanical forces on the myocardium can alter its electrical properties. The effect can be large enough to induce ectopic beats or fibrillation. However, the role of MEF at physiological levels of mechanical stress is not clear. We have investigated alteration in action potential morphology in rat and guinea pig ventricle and in rat atrial tissue at levels of stretch near the plateau of the Frank-Starling curve. Stretch of >100 mm.Hg End Diastolic Left Ventricular Pressure (EDLVP or rapidly applied stretch (EDLVP increased by 25 mm.Hg within 100 ms often triggered ectopic beats in isolated rat and guinea-pig hearts. However, ventricular epicardial monophasic action potentials (MAPs recorded during stretch to EDLVP up to 30 mm. Hg showed no consistent changes in action potential duration (at APD20, APD50 or APD80 in either species. MAP recording detected APD prolongation with very small concentrations of 4-AP (10 μM, confirming the discrimination of the recording technique. In isolated rat atrial strips, no changes in intracellular action potential morphology or membrane potential were seen when stretched to levels producing an optimum increase in contractility. We conclude that alteration in action potential morphology with stretch does not contribute to the Frank-Starling relation in ventricle of rat or guinea-pig isolated heart, or in rat atrial tissue.

    An orthonormal basis of modified coherent states is constructed. Each member of the basis is an infinite sum of coherent states on a von Neumann lattice. A single state is assigned to each unit cell of area h (Planck constant) in the phase plane. The uncertainties of the coordinate x and the square of the momentum p 2 for these states are shown to be similar to those for the usual coherent states. Expansions in the newly established set are discussed and it is shown that any function in the kq-representation can be written as a sum of two fixed kq-functions. Approximate commuting operators for x and p 2 are defined on a lattice in phase plane according to von Neumann's prescription. (leeter to the editor)

    Freiherr Christian Johann Dietrich Theodor von Grotthuss (1785-1822) lived and worked in Lithuania. Inspired by Volta's pile he proposed the first theory of water electrolysis, which was published in 1805 in Rome. Michael Faraday acknowledged T. Grotthuss for this theory in his further investigations of electrolysis processes. Having studied in Germany and France Grotthuss brought science to province by establishing his laboratory in Gedučiai village in his mother's real estate. Lithuanian scientists are proud that life of Theodor von Grotthuss was related to this country. Many events to remember this prominent scientist are organised in Vilnius and other places. His works and example provided a good basis for further development of electrochemical science in Lithuania. Grotthuss insights into the mechanism of proton transport still are of great relevance to such areas of modern science as membrane biochemistry, energy conversion and storage.

  20. Inattentional blindness and the von Restorff effect.

    Schmidt, Stephen R; Schmidt, Constance R

    2015-02-01

    Sometimes we fail to notice distinctive or unusual items (inattentional blindness), while other times we remember distinctive items more than expected items (the von Restorff effect). A three-factor framework is presented and tested in two experiments in an attempt to reconcile these seemingly contradictory phenomena. Memory for different types of unexpected stimuli was tested after an easy or difficult Stroop color-naming task. Highly arousing taboo words were well remembered even when the difficult Stroop task limited attentional resources. However, a conceptual isolation effect was only observed when the nature of the category change was highlighted by the Stroop task, the Stroop task was easy, and/or the isolated targets enjoyed a retrieval advantage relative to comparison targets. As proposed in the three-factor framework, the arousing qualities of the stimuli, the attentional demands of the primary task, and the relevance of isolated features at encoding and retrieval combine to produce inattentional blindness and the von Restorff effect.

    Ens, Konstantin; Wenzel, Fabian; Fischer, Bernd

    Die lokale Symmetrie von Hirnscans entlang der Sagittalebene zu ermitteln und zu modizifieren, ist für eine Reihe neurologischer Anwendungen interessant. Beispielsweise kann der voxelweise Vergleich von rechter und linker Hirnhälfte nur dann Aufschluss über die Lokalisierung von Läsionen geben, wenn durch Transformation ein Hirnscan eine möglichst hohe Symmetrie aufweist. Ein weiteres Anwendungsgebiet ist die Visualisierung von medialen Hirnschnitten, für die die Trennfläche beider Hirnhälfte möglichst eben sein sollte. Diese Arbeit stellt die Entwicklung eines Verfahrens vor, mit dessen Hilfe die Symmetrie von Hirnaufnahmen entlang der Sagittalebene verbessert werden kann. Dies geschieht unter Verwendung von aktiven Konturen, die mit Hilfe einer neuartigen Kostenfunktion gesteuert werden. Experimente am Ende der Arbeit mit strukturellen Kernspinaufnahmen demonstrieren die Leistungsfähigkeit des Verfahrens.

  17. A bicategorical approach to Morita equivalence for von Neumann algebras

    International Nuclear Information System (INIS)

    Brouwer, R. M.

    2003-01-01

    We relate Morita equivalence for von Neumann algebras to the ''Connes fusion'' tensor product between correspondences. In the purely algebraic setting, it is well known that rings are Morita equivalent if they are equivalent objects in a bicategory whose 1-cells are bimodules. We present a similar result for von Neumann algebras. We show that von Neumann algebras form a bicategory, having Connes's correspondences as 1-morphisms, and (bounded) intertwiners as 2-morphisms. Further, we prove that two von Neumann algebras are Morita equivalent iff they are equivalent objects in the bicategory. The proofs make extensive use of the Tomita-Takesaki modular theory

    1983-09-01

    The attempt of Seeger and Frank to reinterpret the annealing in recovery Stage III in gold in terms of the mobile single interstitial is discussed. Considering the experimental data of Stage III in irradiated samples and for the annealing stage observed in quenching samples around room temperature, it is concluded that the assignment of the recovery in these two stages to two different elementary defects is unjustified. It is further demonstrated that the interpretation of recovery Stage III by interstitial migration is in conflict with the direct observations of vacancies migrating in this stage and that the interpretation of the recovery measurements in radiation doped gold by the two interstitial model leads to inconsistencies. The attempt to interpret recovery Stage III in gold by interstitial migration must therefore be rejected and the activation energy of 0.71 eV measured for this stage must be attributed to the migration energy of single vacancies.

    Full Text Available Already fifty years ago, Frank Robert Tangherlini, an American theoretical physicist, suggested an original procedure which, targeting the synchronization of clocks located in two different inertial reference frames of the space, was di erent from that Einstein had introduced. As a result of these, Tangherlini had deduced the so-called the Tangher- lini transformations, which are a sort of the transformations of the spatial coordinates and time being moved from one inertial reference frame into another one. The Tangher- lini transformations differ from the Lorentz transformations (which can be meant clas- sic ones in the theory of relativity and, in particular, suggest the velocity of light to be anisotropic in a moving inertial reference frame. The Tangherlini transformations be- ing applied provide adequate explanations to all well-known interference experiments checking of the Special Theory of Relativity.

    1977-01-01

    Hones 1977 points out the marked disagreement between the plasma flow measurements reported by Frank et al. 1976 and those obtained with the LASL plasma analyzer. He suggests (1) that solar ultraviolet background rates may have been incorrectly accounted for in the computation of proton bulk flows in the magnetotail as reported by Frank et al. 1976 and (2) that bulk flows with substantial speeds, i.e., those speeds greater than 50 km per sec, are seldom encountered in the plasma sheet at geocentric radial distances approx. equal to 35 R sub E. It is demonstrated that such ultraviolet responses were carefully considered by Frank et al. 1976 and thus the conclusion is maintained that bulk flows greater than 50 km per sec frequently occur in the plasma sheet at these radial distances. Further, a direct comparison of the capabilities of the LASL plasma analyzer employed by Hones and of the LEPEDEA Frank et al., 1976 indicates that there are rather severe restrictions on which plasmas in the plasma sheet can be properly measured to gain proton temperatures, number densities and flow velocities with the LASL plasma analyzer.

    Von Recklinghausen's disease belongs to a group of neurocutaneous syndromes and is characterised by skin, nerve and bone abnormalities. We present a case of von Recklinghausen's disease and precocious puberty in 7-year-old boy. At the age of three café au lait spots on the skin and an incranial tumour situated near the optic chiasm--qualified as inoperable--were discovered. At the age of 7 first signs of precocious puberty appeared (pubic hair P3 and enlargement of the testes (15 ml) and penis). Laboratory measurements included: LH 7.5 mIU/ml, FSH 1.1 mIU/ml, testosterone 183 ng/ml, assessment of bone age: 9 years. The response to LHRH stimulation was characteristic for true precocious puberty (LH 15.9 mIU/ml and FSH 1.5 mIU/ml after 30 minutes). The MRI of the brain showed a tumour of the suprasellar region with compression of pituitary stalk. True precocious puberty was diagnosed. Treatment with Diphereline was introduced. At present the boy is 9 years old and has been treated with Diphereline for 16 months. The volume of the testicles has decreased to 7 ml and loss of pubic hair was noted. The MRI does not show any progression in tumour growth. The authors would like to underline the need of close observation of children with von Reclinghausen disease with regard to possibility of uncovering true precocious puberty which is critical for rapid diagnosis and introduction of correct treatment.

    Full Text Available Article in English.The author's recently published monograph on Alexander von Humboldt describes the multiple images of this great cultural icon. The book is a metabiographical study that shows how from the middle of the nineteenth century to the present day Humboldt has served as a nucleus of crystallisation for a variety of successive socio-political ideologies, each producing its own distinctive representation of him. The historiographical implications of this biographical diversity are profound and support current attempts to understand historical scholarship in terms of memory cultures.

Guy von Dardel came to CERN when it was founded in 1954 and was a full-time staff member until 1964, performing several experiments and working on technical developments. These included the first measurement of the neutral pion’s life-time. Called to Lund University in 1964, he became professor there in 1965 and director of the 1.2 GeV electron accelerator. In the late 1960s, he performed an experiment at CERN’s PS that measured the decays of the Λ. Then, in the early 1970s, he involved the Lund group in a series of experiments at the Intersecting Storage Rings (ISR), where he measured the production of various types of particles. In particular, he participated in a series of experiments that observed the production of a high abundance of particles with large transverse momenta. This required an explanation...

  3. Translational Medicine Advances in von Willebrand Disease

    Following the recognition of von Willebrand disease (VWD) in 1926 and the cloning of the gene for von Willebrand factor (VWF) in 1985, significant advances have been made in our fundamental knowledge of both the disease and the protein. Some of this new knowledge has also begun to impact the clinical management of VWD. First, the progressive increase in our understanding of the molecular genetic basis of VWD has resulted in rational applications of molecular testing to complement the current range of phenotypic tests for VWD. These molecular genetic strategies are most effectively directed at the prenatal diagnosis of type 3 VWD and confirmatory testing for types 2B and 2N disease. In contrast, the use of molecular testing to clarify the diagnosis of type 1 VWD is of marginal benefit, at best. In terms of VWD therapies, a new recombinant VWF concentrate has recently completed successful clinical trials and is now awaiting more widespread application. There have even been some pre-clinical successes with VWF gene transfer although the clinical rationale for this therapeutic strategy needs careful consideration. Much more remains to be learnt about the biology of VWF and further translational advances for the enhancement of VWD care will inevitably be realized. PMID:23809112

    Hydrological tracer techniques are a means of making statements on the direction and speed of underground water. One of the simpler tasks is to find out whether there is hydrological communication between two given points. This requires a determination of the direction of flow, which places less exacting demands on the properties of the tracer than does the task of determining the flow velocity of underground water. Tracer methods can serve to infer from flow velocity the distance (flow) velocity, which is defined as the ratio between the distance between two points located in flow direction and the actual time it takes water to flow from one to the other. [Deutsch] Mit Hilfe der hydrologischen Markierungstechniken koennen Aussagen ueber die Richtung und die Geschwindigkeit von Bewegungen des unterirdischen Wassers gemacht werden. Der einfachere Fall liegt vor, wenn festgestellt werden soll, ob zwischen zwei Punkten eine hydrologische Verbindung besteht. Bei dieser Fliessrichtungsbestimmung sind die Forderungen an die Eigenschaften der einzusetzenden Tracer geringer als bei der Bestimmung der Geschwindigkeit des unterirdischen Wassers. Von den Geschwindigkeiten des unterirdischen Wassers ist die Abstands-(Fliess)geschwindigkeit, die definiert ist durch das Verhaeltnis aus dem Abstand und der wahren Fliesszeit zwischen zwei in Bewegungsrichtung gelegenen Punkten, durch Tracermethoden zu bestimmen.

In seinem Pariser Büro empfängt der 71jährige Naturforscher Alexander von Humboldt den jungen Preußen Ludwig Leichhardt. Der angehende Naturwissenschaftler erhofft sich Zuspruch und Empfehlung des berühmten Alexander von Humboldts. Die Unterredung ist kurz und verläuft für Leichhardt ergebnislos. Es wird das einzige Treffen der beiden Naturwissenschaftler bleiben. Aus heutiger Sicht unverständlich, da Ludwig Leichhardt und Alexander von Humboldt mehr verband, als ihre Leidenschaft für die Naturwissenschaften. Viel zu wenig ist sich bis jetzt den biographischen Analogien und den vergleichbaren geographischen Leistungen der beiden Preußen gewidmet worden. Abstract During July 1841 a meeting between two men takes place, which seems to have been extraneous, but turns out to be a significant historical incident. 71 year old natural scientist Alexander von Humboldt welcomes young Ludwig Leichhardt from Prussia in his office in Paris. The prospective young scientist expects help and references from famous Alexander von Humboldt. The conversation is short and ends from Leichhardt’s point of view without results. Unfortunately this is going to be the only meeting between the two scientists even though the two Prussians have more in common than their passion for the natural sciences. Way too seldomly have biographical analogy and geographical productivity of the two men been compared.

    Full Text Available Orientation: This article addresses the issues of executive remuneration and whether it was excessive or not. Research purpose: On 05 August 2015, the US Securities and Exchange Commission (SEC adopted a rule to operationalise Section 953(b of the Dodd-Frank Wall Street Reform and Consumer Protection Act 2010 (Dodd-Frank or the Dodd-Frank Act 2010, the ‘pay ratio provision’, as part of a process to ensure sound corporate governance and shed light on assertions that corporate executive remuneration was excessive and detrimental to the economic wellbeing of the USA. This pay ratio rule will be operative starting from 2017 and requires public firms to publish the ratio of chief executive officer (CEO remuneration to the median remuneration of all its employees. Hence, it is a measure of income distribution. It does not reveal the relationship between executive compensation and the value added to the firm by executives. In anticipation of this rule becoming mandatory and as part of a quest to quantify the value of executives to the firm, Paulo and Le Roux (2014 developed an approach to measure the value executives add to the firm, drawing from audited financial statements and thereby demonstrating that the value added by executive management could be measured according to the requirements of sound research methodology and rigorous epistemology. Motivation for the study: Statutory enactment of the pay ratio provision provided the impetus to create an index, the Paulo–Le Roux Index, that shows how much executives are paid in relation to how much value they add to the firm.

    2013-01-01

    The state of a quantum system being described by a density operator ρ, quantum statistical mechanics calls the quantity - kTr( ρln ρ), introduced by von Neumann, its von Neumann or statistical entropy. A 1999 Shenker's paper initiated a debate about its link with the entropy of phenomenological thermodynamics. Referring to Gibbs's and von Neumann's founding texts, we replace von Neumann's 1932 contribution in its historical context, after Gibbs's 1902 treatise and before the creation of the information entropy concept, which places boundaries into the debate. Reexamining von Neumann's reasoning, we stress that the part of his reasoning implied in the debate mainly uses thermodynamics, not quantum mechanics, and identify two implicit postulates. We thoroughly examine Shenker's and ensuing papers, insisting upon the presence of open thermodynamical subsystems, imposing us the use of the chemical potential concept. We briefly mention Landau's approach to the quantum entropy. On the whole, it is shown that von Neumann's viewpoint is right, and why Shenker's claim that von Neumann entropy "is not the quantum-mechanical correlate of thermodynamic entropy" can't be retained.

    Full Text Available Receptor activator of nuclear factor (NF- κB ligand (RANKL, sein zellulärer Rezeptor RANK und der Decoy-Rezeptor Osteoprotegerin (OPG stellen ein essentielles Zytokinsystem für die Zellbiologie von Osteoklasten dar. Verschiedene Untersuchungen belegen die Bedeutung von Störungen des OPG/RANKL/RANK-Systems bei der Pathogenese metabolischer Knochenerkrankungen. In dieser Arbeit werden die wichtigsten Störungen des OPG/RANKL/RANK-Systems bei verschiedenen Osteoporoseformen dargestellt. Östrogenrezeptor- (ER- Agonisten wie 17 β-Östradiol, Raloxifen und Genistein stimulieren die osteoblastäre Produktion von OPG durch Aktivierung von ER- α in vitro, während Lymphozyten von Patientinnen mit Östrogenmangel RANKL überexprimieren. Die parenterale Gabe von OPG vermag den mit Östrogenmangel assoziierten Knochenverlust im Tiermodell und in einer kleineren klinischen Studie zu verhindern. Glukokortikoide und Immunsuppressiva steigern gleichzeitig die RANKL-Expression und hemmen die OPG-Produktion in osteoblastären Zellen in vitro. Glukokortikoide sind auch in vivo imstande, die OPG-Serumspiegel deutlich zu reduzieren. Dagegen hemmen biomechanische Reize in vitro die RANKL-Produktion und steigern die OPG-Produktion. Ein Fehlen dieser biomechanischen Reize bei längerer Immobilisierung kann daher den RANKL/OPG-Quotienten steigern, während die tierexperimentelle Immobilisierungs-Osteoporose durch die parenterale Gabe von OPG gemildert werden kann.

  17. Narrative empathy and illness memoirs: Arthur Frank's At the Will of the Body and Kathlyn Conway's Ordinary Life.

    Baena, Rosalia

    2017-09-01

    This article analyses the concept of narrative empathy in illness memoirs. These texts negotiate the narrative identity of an autobiographer as he or she recounts the disruptive experience of illness, an experience in which physical and emotional traces dramatically and definitively shape our sense of self. While narrative emotions are certainly deployed in these autobiographies in order to connect with the readers and promote social change, this empathic connection is not so much aimed at arousing compassion but rather more positive emotions on the experience of illness. I will explore the emotional representations of cancer in Arthur Frank's At the Will of the Body (1991) and Kathlyn Conway's Ordinary Life: A Memoir of Illness (1997), focusing on the identity strategies these authors use in order to become affirmative models of disability and illness, showing the damaging effects not of disease or impairment but, rather, of the cultural mythologies that interpret those conditions in reductive or disparaging ways.

    When redeveloping buildings it is common to use window constructions with air-tight rabbets which obviate the inflow of fresh air almost entirely. This leads to the well-known structural-physics and hygienic consequences. As an added effect, the distinctly enhanced thermal insulation results in changes in dynamic heat loss. The paper focuses on the issues of how to safeguard the inflow of fresh air, and the heating capacity of radiators. (MSK) [Deutsch] Da die bei Gebaeudesanierungen eingesetzten fugendichten Fensterkonstruktionen die Nachstroemmoeglichkeiten fuer die Zuluft fast ganz unterbinden, fuehrt das zu den bekannten bauphysikalischen und hygienischen Konsequenzen.

  19. Of von Willebrand factor and platelets.

    2015-01-01

    Hemostasis and pathological thrombus formation are dynamic processes that require multiple adhesive receptor-ligand interactions, with blood platelets at the heart of such events. Many studies have contributed to shed light on the importance of von Willebrand factor (VWF) interaction with its platelet receptors, glycoprotein (GP) Ib-IX-V and αIIbβ3 integrin, in promoting primary platelet adhesion and aggregation following vessel injury. This review will recapitulate our current knowledge on the subject from the rheological aspect to the spatio-temporal development of thrombus formation. We will also discuss the signaling events generated by VWF/GPIb-IX-V interaction, leading to platelet activation. Additionally, we will review the growing body of evidence gathered from the recent development of pathological mouse models suggesting that VWF binding to GPIb-IX-V is a promising target in arterial and venous pathological thrombosis. Finally, the pathological aspects of VWF and its impact on platelets will be addressed.

    2010-01-01

    During reductions in central blood volume while heat stressed, a greater decrease in stroke volume (SV) for a similar decrease in ventricular filling pressure, compared to normothermia, suggests that the heart is operating on a steeper portion of a Frank-Starling curve. If so, volume loading...... of heat-stressed individuals would shift the operating point to a flatter portion of the heat stress Frank-Starling curve thereby attenuating the reduction in SV during subsequent decreases in central blood volume. To investigate this hypothesis, right heart catheterization was performed in eight males...... from whom pulmonary capillary wedge pressure (PCWP), central venous pressure and SV (via thermodilution) were obtained while central blood volume was reduced via lower-body negative pressure (LBNP) during normothermia, whole-body heating (increase in blood temperature 1 degrees C), and during whole...

  7. Pure Jauch-Piron states on von Neumann algebras

    International Nuclear Information System (INIS)

    Hamhalter, J.

    1993-01-01

    We study Jauch-Piron states and two-valued measures on von Neumann algebra. We prove as the main result that, under some set-theoretical assumption, a pure state of a von Neumann algebra A not containing a central abelian portion is Jauch-Piron if and only if it is σ-additive. Moreover, we show that this result holds for type I factor indenpendently on the set-theoretical axiomatics. As a consequence we obtain a lucid characterization of pure Jauch-Piron states on von Neumann algebras acting on a Hilbert space with real-nonmeasurable dimension (this can be viewed as a generalization of the paper). We also characterize the von Neumann algebras whose logic of projections is Jauch-Piron. Finally, we prove that every two-valued measure on the projection logic of A, where A contains no type I 2 central portion, has to be concentrated at an abelian direct summand of A. (orig.)

  15. Von Neumann's impossibility proof: Mathematics in the service of rhetorics

    Science.gov (United States)

    Dieks, Dennis

    2017-11-01

    According to what has become a standard history of quantum mechanics, in 1932 von Neumann persuaded the physics community that hidden variables are impossible as a matter of principle, after which leading proponents of the Copenhagen interpretation put the situation to good use by arguing that the completeness of quantum mechanics was undeniable. This state of affairs lasted, so the story continues, until Bell in 1966 exposed von Neumann's proof as obviously wrong. The realization that von Neumann's proof was fallacious then rehabilitated hidden variables and made serious foundational research possible again. It is often added in recent accounts that von Neumann's error had been spotted almost immediately by Grete Hermann, but that her discovery was of no effect due to the dominant Copenhagen Zeitgeist. We shall attempt to tell a story that is more historically accurate and less ideologically charged. Most importantly, von Neumann never claimed to have shown the impossibility of hidden variables tout court, but argued that hidden-variable theories must possess a structure that deviates fundamentally from that of quantum mechanics. Both Hermann and Bell appear to have missed this point; moreover, both raised unjustified technical objections to the proof. Von Neumann's argument was basically that hidden-variables schemes must violate the ;quantum principle; that physical quantities are to be represented by operators in a Hilbert space. As a consequence, hidden-variables schemes, though possible in principle, necessarily exhibit a certain kind of contextuality. As we shall illustrate, early reactions to Bohm's theory are in agreement with this account. Leading physicists pointed out that Bohm's theory has the strange feature that pre-existing particle properties do not generally reveal themselves in measurements, in accordance with von Neumann's result. They did not conclude that the ;impossible was done; and that von Neumann had been shown wrong.

    Full Text Available Johann Friedrich Herbart (1776-1841 gilt als der Begründer der wissenschaftlichen Pädagogik. In diesem Beitrag wird zu zeigen versucht, dass Herbart die Unterstützung politischer Bildung als eine Aufgabe von Regierung, Unterricht und Zucht bestimmt und in seinem Werk wichtige „Bausteine“ für eine Theorie der politischen Bildung unter den Bedingungen von Erziehung vorlegt hat. Nach Herbart ist das politische Selbst- und Weltverhältnis auf Sachverhalte bezogen, die nicht nur die Lebensführung einzelner Menschen, sondern die Lebensführung einer Mehrzahl von Menschen betreffen. Nicht das Zusammenleben von Menschen generell ist jedoch Orientierungsgesichtspunkt des politischen Selbst- und Weltverhältnisses, sondern nur das problematisch gewordene Zusammenleben. Politik ergibt sich nach Herbart aus einem Konflikt hinsichtlich der Frage, wie das Zusammenleben von Menschen geregelt sein sollte. Während die Regierung lediglich mittelbar einen Beitrag zur politischen Bildung leistet, indem sie die Voraussetzungen für Unterricht und Zucht bereitstellt, fungieren die beiden zuletzt genannten Formen von Erziehung als die eigentlichen Medien, in denen die politische Bildung im Sinne Herbarts ihren Ort hat.

    Full Text Available A one-dimensional numerical model that simulates the effects of whitecapping waves was used to investigate the importance of whitecapping waves to vertical mixing at a 3-meter-deep site in Franks Tract in the Sacramento-San Joaquin Delta over an 11-day period. Locally-generated waves of mean period approximately 2 s were generated under strong wind conditions; significant wave heights ranged from 0 to 0.3 m. A surface turbulent kinetic energy flux was used to model whitecapping waves during periods when wind speeds > 5 m s-1 (62% of observations. The surface was modeled as a wind stress log-layer for the remaining 38% of the observations. The model results demonstrated that under moderate wind conditions (5–8 m s-1 at 10 m above water level, and hence moderate wave heights, whitecapping waves provided the dominant source of turbulent kinetic energy to only the top 10% of the water column. Under stronger wind (> 8 m s-1, and hence larger wave conditions, whitecapping waves provided the dominant source of turbulent kinetic energy over a larger portion of the water column; however, this region extended to the bottom half of the water column for only 7% of the observation period. The model results indicated that phytoplankton concentrations close to the bed were unlikely to be affected by the whitecapping of waves, and that the formation of concentration boundary layers due to benthic grazing was unlikely to be disrupted by whitecapping waves. Furthermore, vertical mixing of suspended sediment was unlikely to be affected by whitecapping waves under the conditions experienced during the 11-day experiment. Instead, the bed stress provided by tidal currents was the dominant source of turbulent kinetic energy over the bottom half of the water column for the majority of the 11-day period.

    The RCP method was designed as a residue-optimised alternative to the thermally optimised grate firing of residual wastes. Its technical realisation and development to market maturity took no more than 5 years. In the first process stage the waste is converted to high-carbon pyrolysis charcoal and high-rank gas in the absence of oxygen. In the second stage these substances are oxidised by addition of oxygen. The resulting temperature causes the non-combustible constituents of the slag to melt. In a third, optional, stage this molten slag can be liberated of (heavy) metals to such an extent that it can subsequently be used directly as additive for grinding. Further exhaust gas treatment is facilitated by the use of a circulatory fluidised-bed secondary combustion chamber. Despite the reduced flue gas volume and resultant higher pollutant concentrations in the crude gas, overall emissions are lower than in conventional plants. [Deutsch] Das reststoffoptimierte RCP Verfahren ist als Alternative zur thermisch optimierten Rostverbrennung von Restabfaellen konzipiert. In nur fuenf Jahren wurde das Verfahren technisch umgesetzt und zur Marktreife entwickelt. In einer ersten Stufe des Verfahrens wird der Abfall unter Luftabschluss in einen kohlenstoffreichen Pyrolysekoks und eine heizwertreiches Gas umgesetzt. Im zweiten Schritt werden diese Stoffe unter Zugabe von Sauerstoff oxidiert. Dabei treten Temperaturen auf, bei denen die nichtbrennbaren Bestandteile der Schlacke schmelzen. Optional wird diese Schmelzschlacke in einem dritten Schritt derart von (Schwer-) Metallen befreit, dass sie anschliessend direkt als Zement-Zumahlstoff eingesetzt werden kann. Die Nutzung der zirkulierenden Wirbelschicht - Nachbrennkammer zur Abgasbehandlung vereinfacht die weitergehende Abgasbehandlung. Trotz verringertem Rauchgasvolumen und damit hoeheren Schadstoffkonzentrationen im Rohgas werden die Gesamtemissionen gegenueber konventionellen Anlagen verringert. (orig./SR)

    2008-02-01

    Richard von Volkmann (1830-1889), one of the most important surgeons of the 19(th) century, is regarded as one of the fathers of orthopaedic surgery. He was a contemporary of Langenbeck, Esmarch, Lister, Billroth, Kocher, and Trendelenburg. He was head of the Department of Surgery at the University of Halle, Germany (1867-1889). His popularity attracted doctors and patients from all over the world. He was the lead physician for the German military during two wars. From this experience, he compared the mortality of civilian and war injuries and investigated the general poor hygienic conditions in civilian hospitals. This led him to introduce the "antiseptic technique" to Germany that was developed by Lister. His powers of observation and creativity led him to findings and achievements that to this day bear his name: Volkmann's contracture and the Hueter-Volkmann law. Additionally, he was a gifted writer; he published not only scientific literature but also books of children's fairy tales and poems under the pen name of Richard Leander, assuring him a permanent place in the world of literature as well as orthopaedics.

  11. Geschichte der Natur bei Alexander von Humboldt

    Christian Helmreich

    2009-05-01

    Full Text Available Article in German, Abstracts in English, German and French.This article analyses the importance of an historical view of nature in the works of Alexander von Humboldt. In several of his first writings, Humboldt seems to outline the importance of what one may call history of nature. But even before his famous American travel, his position changed and he became reluctant to accept the seriousness of historical enquiry in the area of natural sciences: if we want to reconstruct the past state of nature, we cannot rely on empirical proofs; and history of nature is therefore necessarily based on uncertain hypotheses. Humboldt kept his sceptical attitude in the first decades of the 19th century, despite the positive results of the palaeontological researches of his scientific colleagues. However, he gradually convinced himself of the scientific interest of historical investigations in the natural sciences. The Cosmos paradoxally displays two apparently conflicting points of view: in his methodological remarks, Humboldt maintains that precise accounts of the past state of nature are out of reach of human knowledge, yet elsewhere in the same Cosmos he gives broad and rather vivid descriptions of the eventful history of nature.

They illustrate their method with free groups, triangular groups and finite cyclic groups, for which they obtain optimal time hypercontractive L_2 \\to L_q inequalities with respect to the Markov process given by the word length and with q an even integer. Interpolation and differentiation also yield general L_p \\to L_q hypercontrativity for 1 < p \\le q < \\infty via logarithmic Sobolev inequalities. The authors' method admits further applications to other discrete groups without small loops as far as the numerical part-which varies from one group to another-is implemented and tested on a computer. The authors also develop another combinatorial method which does not rely on computational estimates and provides (non-optimal) L_p \\to L_q hypercontractive inequalities for a larger class of groups/lengths, including any finitely generated group equipped with a condit...

    2013-01-01

    Full Text Available Context: Acquired von Willebrand syndrome (AVWS is a rare bleeding disorder that mimics the inherited form of von Willebrand disease (VWD in terms of laboratory findings and clinical presentation. Aims: To study the etiology of acquired VWD. Settings and Design: The patients referred from various hospitals in and out of Mumbai were included in the study. Materials and Methods: Six patients with AVWS diagnosed at this center over the last 10 years were analyzed against 171 patients with inherited VWD. The differential diagnosis of AVWS was made based on reduced levels of von Willebrand antigen and von Willebrand ristocetin cofactor, decrease in ristocetin induced platelet aggregation, absence of correction in mixing studies with no prior history of bleeding problems and a negative family history for bleeding disorders. Results: In three patients, the disease was associated with systematic lupus erythematosus, out of which one was also associated with Kikuchi lymphadenitis and second with autoimmune hemolytic anemia. Fourth case was associated with hypothyroidism and fifth was a case of dermatitis and vitiligo. The last patient was a case of hemophilia A with Burkitts lymphoma, who developed autoantibodies to von Willebrand factor. Except two patients, all other patients responded to immune suppressive therapy with corticosteroids, while the patient with hypothyroidism responded to oral thyroxine. Conclusion: AVWS is a rare condition and may often be missed or diagnosed as inherited disease associated with heterogeneous disease conditions.

    The impacts on human health and the natural environment of using natural gas, Diesel and petrol as fuels for city buses and passenger cars are compared in a Life Cycle Assessment. In addition to the burning of the fuels in the engines, this assessment also comprises the upstream processes of the fuel supply chain. Despite the increased energy demand of the vehicles, natural gas is associated with the lowest impacts overall for both city buses and passenger cars. The health impacts that can be avoided through the use of natural gas instead of Diesel or petrol thereby differ only weakly between the use of the vehicles in cities of various sizes within Germany. From the perspective of environmental protection, the market introduction of natural gas vehicles therefore does not need remain limited to large cities within agglomerated regions. (orig.) [German] Die Auswirkungen der Verwendung von Erdgas, Diesel und Benzin als Kraftstoffe fuer Stadtbusse und Pkw auf die menschliche Gesundheit und die natuerliche Umwelt werden in einer Oekobilanz verglichen. Diese umfasst neben der motorischen Verbrennung der Kraftstoffe auch die vorgelagerten Prozessketten der Kraftstoffbereitstellung. Sowohl fuer Stadtbusse als auch fuer Pkw schneidet Erdgas trotz eines energetischen Mehrbedarfes der Fahrzeuge insgesamt am guenstigsten ab. Die durch den Einsatz von Erdgas anstelle von Diesel oder Benzin vermeidbaren Gesundheitsschaeden unterscheiden sich dabei zwischen einem Einsatz der Fahrzeuge in Staedten verschiedener Groesse innerhalb von Deutschland nur wenig. Die Markteinfuehrung von Erdgasfahrzeugen muss also aus Sicht des Umweltschutzes nicht auf grosse Staedte in Ballungsgebieten beschraenkt bleiben. (orig.)

    The report is aimed at collecting and documenting the state of the art and the extensive know how of experts and pipeline operators with regard to judging the structural integrity of pipelines. In order to assess the actual mechanical strength of pipelines based on measurement results obtained by inspection pigs, guidance is given for future processing, which eventually can be used as a basis for an industry standard. A literature study of the commercially available types of inspection pigs describes and synoptically lists the respective pros and cons. In essence the report comprises besides check lists of operating data for the pipeline and the pig runs mainly the evaluation of defects and respective calculating procedures. Included are recommendations regarding maintenance planning, verification of defects as well as repetition of pig runs. (orig.) [German] Ziel des Berichtes ist die Erfassung und Dokumentation zum derzeitigen Stand der Technik und des vorhandenen umfangreichen Know-how von Sachverstaendigen und Pipelinebetreibern auf dem Gebiet der sicherheitstechnischen Beurteilung von Pipelines.

    We discuss information-theoretic concepts on infinite-dimensional quantum systems. In particular, we lift the smooth entropy formalism as introduced by Renner and collaborators for finite-dimensional systems to von Neumann algebras. For the smooth conditional min- and max-entropy, we recover similar characterizing properties and information-theoretic operational interpretations as in the finite-dimensional case. We generalize the entropic uncertainty relation with quantum side information of Tomamichel and Renner and discuss applications to quantum cryptography. In particular, we prove the possibility to perform privacy amplification and classical data compression with quantum side information modeled by a von Neumann algebra

    Die Psoriasis-Arthritis (PsA) gehört zu den chronisch entzündlichen Gelenkerkrankungen. Trotz zahlreicher versorgungswissenschaftlicher Studien in Deutschland liegen zur pharmazeutischen Versorgungssituation von PsA-Patienten bisher kaum aktuelle Ergebnisse vor. Mit Hilfe einer systematischen Literaturrecherche sowie anhand von Routinedaten der Allgemeinen Ortskrankenkasse (AOK) Rheinland/Hamburg wird ein aktueller Überblick über die pharmazeutische Versorgung von PsA-Patienten in Deutschland gegeben. Selektiert wurden Versicherte aus dem ambulanten und stationären Bereich, die im 1. und 2. Quartal des Jahres 2014 die gesicherte Abrechnungsdiagnose Psoriasis-Arthritis L40.5+ aufwiesen. Anschließend wurden auf Basis dieser "vorab definierten" Kohorte die Arzneimitteldaten für 5 Jahre (01.01.2010-31.12.2014) abgerufen. Es konnten insgesamt n  =  3205 Versicherte (45 % männlich, 55 % weiblich) der AOK Rheinland/Hamburg mit einer gesicherten PsA-Diagnose selektiert werden. Das Durchschnittsalter betrug 58,9 Jahre. 53,7 % der PsA-Patienten wurden mit systemischen PsA-relevanten Arzneimitteln versorgt. Nichtsteroidale Antirheumatika (NSAR) wurden am häufigsten verordnet, gefolgt von systemischen Glucocorticoiden. Von den selektierten PsA-Patienten, die eine Systemtherapie erhielten, wurden 72,1 % mittels einer Disease-modifying-antirheumatic-Drug (DMARD)-Monotherapie behandelt, gefolgt von der Kombinationstherapie aus DMARDs und Biologika (20,9 %). Die pharmakologische Therapie der PsA muss eine Gewährleistung zwischen adäquater Versorgung der PsA mit Verhinderung der Krankheitsprogression und ökonomischer Verantwortung darstellen. © 2018 Deutsche Dermatologische Gesellschaft (DDG).

  11. Von-Neumann and Beyond: Memristor Architectures

    KAUST Repository

    Naous, Rawan

    2017-05-01

    An extensive reliance on technology, an abundance of data, and increasing processing requirements have imposed severe challenges on computing and data processing. Moreover, the roadmap for scaling electronic components faces physical and reliability limits that hinder the utilization of the transistors in conventional systems and promotes the need for faster, energy-efficient, and compact nano-devices. This work thus capitalizes on emerging non-volatile memory technologies, particularly the memristor for steering novel design directives. Moreover, aside from the conventional deterministic operation, a temporal variability is encountered in the devices functioning. This inherent stochasticity is addressed as an enabler for endorsing the stochastic electronics field of study. We tackle this approach of design by proposing and verifying a statistical approach to modelling the stochastic memristors behaviour. This mode of operation allows for innovative computing designs within the approximate computing and beyond Von-Neumann domains. In the context of approximate computing, sacrificing functional accuracy for the sake of energy savings is proposed based on inherently stochastic electronic components. We introduce mathematical formulation and probabilistic analysis for Boolean logic operators and correspondingly incorporate them into arithmetic blocks. Gate- and system-level accuracy of operation is presented to convey configurability and the different effects that the unreliability of the underlying memristive components has on the intermediary and overall output. An image compression application is presented to reflect the efficiency attained along with the impact on the output caused by the relative precision quantification. In contrast, in neuromorphic structures the memristors variability is mapped onto abstract models of the noisy and unreliable brain components. In one approach, we propose using the stochastic memristor as an inherent source of variability in

  13. The role of the Frank-Starling law in the transduction of cellular work to whole organ pump function: a computational modeling analysis.

    Directory of Open Access Journals (Sweden)

    Steven A Niederer

    2009-04-01

    Full Text Available We have developed a multi-scale biophysical electromechanics model of the rat left ventricle at room temperature. This model has been applied to investigate the relative roles of cellular scale length dependent regulators of tension generation on the transduction of work from the cell to whole organ pump function. Specifically, the role of the length dependent Ca(2+ sensitivity of tension (Ca(50, filament overlap tension dependence, velocity dependence of tension, and tension dependent binding of Ca(2+ to Troponin C on metrics of efficient transduction of work and stress and strain homogeneity were predicted by performing simulations in the absence of each of these feedback mechanisms. The length dependent Ca(50 and the filament overlap, which make up the Frank-Starling Law, were found to be the two dominant regulators of the efficient transduction of work. Analyzing the fiber velocity field in the absence of the Frank-Starling mechanisms showed that the decreased efficiency in the transduction of work in the absence of filament overlap effects was caused by increased post systolic shortening, whereas the decreased efficiency in the absence of length dependent Ca(50 was caused by an inversion in the regional distribution of strain.

    In the Introduction the reader is referred back to the academic ceremonials held after Theodore von Kármán's death in Aachen in May 1963. His work as the first director of the Aerodynamisches Institut (Institute of Aerodynamics) of the RWTH Aachen University of Technology from 1913 on and his initiative to re-establish international cooperation after World War I, resulting in the International Union of Theoretical and Applied Mechanics (IUTAM), are commented on. The following chapter describes von Kármán's relation to his former teacher Ludwig Prandtl. Some of von Kármán's scientific contributions during his time in Aachen are briefly reviewed. Thereafter, his first contacts to the California Institute of Technology are covered. Finally, the scientific and political circumstances, which led to von Kármán's decision to leave Germany in the early thirties, are elucidated in some detail. The English translation of the titles of the Aachen papers is given in Appendix I.

    In 1950, Dr. Wernher von Braun and approximately 100 of his team members came to Huntsville, Alabama, to begin work with the Army on what would later become America's historic space program. He would later serve as the first director of the Marshall Space Flight Center and led the development of the Saturn V launch vehicle that launched seven crewed American mission to the moon, as well as America s first space station, Skylab. Von Braun is best known for his team s technical achievements. He realized his dream of exploring outer space by helping place humans on the moon. His engineering and managerial talent during the Apollo era had contributed to a technological revolution. He was by all accounts a good engineer, but he was only one among many. What set Von Braun apart were his charisma, his vision, and his leadership skills. He inspired loyalty and dedication in the people around him. He understood the importance of communicating his vision to his team, to political and business leaders and the public. Today, the Marshall Center continues his vision by pursuing engineering and scientific projects that will continue to open space to exploration. This presentation will discuss Von Braun's impact on Huntsville, the Marshall Center, the nation and the world and look at his contributions in context of where world space exploration is today.

    Full Text Available Dieser Beitrag soll die Forschungslücke zur Darstellung von Behinderungen speziell im Kinderfilm im deutschsprachigen Raum füllen. Auf Basis einer neoformalistisch orientierten Filmanalyse nach Bordwell und Thompson (2008, wird anhand von drei Filmsequenzen eine mögliche Lesart des Kinderfilms "Heidi" (Marcus 2005 entwickelt, um die filmstilistische Darstellung der Gehbehinderung des Mädchens Klara zu untersuchen. Die Ergebnisse werden mit theoretischen Überlegungen zur Problematik der Begriffsbestimmung von Körperbehinderung sowie zur Mobilität und Selbstbestimmung von Menschen mit Körperbehinderungen in Bezug gesetzt. Dabei zeigt sich im Wesentlichen, dass im Kinderfilm "Heidi" (Marcus 2005 Klaras Gehbehinderung als 'heilbare Krankheit' und der Rollstuhl als Einschränkung von Mobilität begriffen wird. Außerdem unterliegt Klara aufgrund ihrer Körperbehinderung überwiegend der Fremdbestimmung von Erwachsenen. Zur Klärung wahrscheinlicher filmischer Bildungspotenziale werden die Ergebnisse schließlich anhand der von Jörissen und Marotzki (2009 entwickelten Orientierungsdimensionen "Wissens-, Handlungs-, Grenz- und Biographiebezug" diskutiert. This article aims to bridge a knowledge gap by showing ways of representing disabilities in the German children film genre. Using Bordwell and Thomson's (2008 neoformalistically orientated film analysis approach, the movie "Heidi" (Marcus 2005 is analysed. Bordwell and Thompson's (2008 method is applied to three sequences of "Heidi" in order to present an interpretation and to discuss the representation of Clara's walking impediment. The results are then associated with theoretical considerations regarding the mobility and self-determination of people with disabilities and problematic definitions of the term 'physical disability'. It is shown that characters in the children's film "Heidi" (Marcus 2005 regard Clara's walking impediment as a 'curable disease' and the wheelchair as a limitation

    1977-01-01

    Various theories regarding the magnetotail are reviewed and discussed. These include the work of Dungey (1961) and Eastman et al., (1976) regarding the generation of the magnetotail, Frank et al., (1976) concerning the so-called magnetotail fireball and its characteristics, and Hones et al., (1976 and 1976a) on the formation of a neutral line across the near-earth plasma sheet near the substorm onset. A detailed discussion of a fireball encounter during 0900-1400 UT in April 1974 is presented, noting plasma and magnetic phenomena observed, and magnetic records from the earth. A critique is made by Hones of the interpretation of this fireball made by Frank et al. In an accompanying reply, Frank et al. comment on the observations made by Hones, with attention to the most evident discrepancy between the two theories, i.e., the generation of large closed magnetic loops in the plasma sheet during magnetic substorms.

  5. Optimierung der Gesichtsklassifikation bei der Erkennung von Akromegalie

    2013-01-01

    Full Text Available In vorausgegangenen Studien konnte gezeigt werden, dass eine Gesichtsklassifikation mittels Gesichtsphotographien zur Diagnostik von Akromegalie mit guten Ergebnissen eingesetzt werden kann. In diesem Artikel werden die grundlegende Vorgehensweise der Klassifikation mittels der Software FIDA erläutert sowie Optimierungsansätze mit dem Ziel diskutiert, diese Methode näher an den klinischen Einsatz zu bringen. Die Gesichtsklassifikation basiert auf „Knotenpunkten“, die verteilt über die jeweilige Frontal- und/oder Seitenansicht des Gesichts platziert werden und den so genannten „Graphen“ bilden. Mittels mathematischer Verfahren erfolgt eine Analyse der zugrunde liegenden Textur des Bildes sowie die Auswertung geometrischer Informationen. Untersucht wird, wie sich die Reduktion von als irrelevant eingestuften Knoten auf das Klassifikationsergebnis auswirkt. Ebenso wird untersucht, wie sich neu definierte Knoten, die die typischen morphologischen Veränderungen der akromegalen Erkrankung im Gesicht berücksichtigen, auf die Klassifizierungsergebnisse auswirken. Die interne Validierung erfolgt an einem Datenset bestehend aus 57 an Akromegalie erkrankten Probanden (29 weiblich, 28 männlich sowie 59 Kontrollen (29 weiblich, 30 männlich. Die externe Validierung wird an einer weiteren Stichprobe gemessen, die zum Zeitpunkt der Präsentation auf der Tagung der European Neuroendocrine Association 2012 in Wien 13 akromegale Patienten (7 weiblich, 6 männlich sowie 45 Kontrollen (25 weiblich, 20 männlich umfasste. Die Datenbank wird ständig durch neue Probanden aus verschiedenen Quellen erweitert. Erste Ergebnisse zeigen, dass die Verwendung von Graphen mit reduzierten Knoten und von neuen Sets von Knoten unter Einbeziehung typischer morphologischer Veränderungen des Gesichts die Klassifizierung weiter verbessert. Diese Ergebnisse ermutigen zu weiteren Untersuchungen an einer erweiterten Datenbank.

  11. The critical role of cognitive-based trait differences in transcranial direct current stimulation (tDCS) suppression of food craving and eating in frank obesity.

    2017-09-01

    Obesity remains a major public health concern and novel treatments are needed. Transcranial direct current stimulation (tDCS) is a neuromodulation technique shown to reduce food craving and consumption, especially when targeting the dorsolateral prefrontal cortex (DLPFC) with a right anode/left cathode electrode montage. Despite the implications to treat frank (non-bingeeating) obesity, no study has tested the right anode/left cathode montage in this population. Additionally, most tDCS appetite studies have not controlled for differences in traits under DLPFC control that may influence how well one responds to tDCS. Hence, N = 18 (10F/8M) adults with frank obesity completed the Dutch Eating Behavior Questionnaire-Restraint and Barratt Impulsiveness Scale, and received 20 min of 2 mA active tDCS and control tDCS session. Craving and eating was assessed at both sessions with a food photo "wanting" test and in-lab measures of total, preferred, and less-preferred kilocalories consumed of three highly palatable snack foods. While main effects of tDCS vs. control were not found, significant differences emerged when trait scores were controlled. tDCS reduced food craving in females with lower attention-type impulsiveness (p = 0.047), reduced preferred-food consumption in males with lower intent to restrict calories (p = 0.024), and reduced total food consumption in males with higher non-planning-type impulsiveness (p = 0.009) compared to control tDCS. This is the first study to find significant reductions in food craving and consumption in a sample with frank obesity using the most popular tDCS montage in appetite studies. The results also highlight the cognitive-based heterogeneity of individuals with obesity and the importance of considering these differences when evaluating the efficacy of DLPFC-targeted tDCS in future studies aimed at treating obesity.

  12. Diagnosis and management of von Willebrand disease: guidelines for primary care.

    Science.gov (United States)

    Yawn, Barbara; Nichols, William L; Rick, Margaret E

    2009-12-01

    Von Willebrand disease is an inherited condition characterized by deficiency of von Willebrand factor, which is essential in hemostasis. The National Heart, Lung, and Blood Institute has released new evidence-based guidelines for the diagnosis and management of the disease. There are three major subtypes of von Willebrand disease, classified as partial quantitative deficiency (low levels) of von Willebrand factor (type 1), qualitative deficiency (type 2), or virtually complete deficiency (type 3). Diagnosis is usually made by reviewing the patient's personal and family history of bleeding and by clinical evaluation for more common reasons for bleeding, supplemented with laboratory tests. Assessment may be used to determine bleeding risk before surgery and other invasive procedures, and to diagnose reasons for unexplained hemorrhaging. Von Willebrand factor levels of 30 IU per dL or lower are required for the definite diagnosis of inherited von Willebrand disease. Persons with levels of 30 to 50 IU per dL may not have the disease, but may need agents to increase von Willebrand factor levels during invasive procedures or childbirth. Treatment is tailored to the subtype of the disease: increasing plasma concentration of von Willebrand factor by releasing endogenous stores with desmopressin or replacing nonexistent or ineffective von Willebrand factor by using human plasma-derived, viral-inactivated concentrates; treatment is often combined with hemostatic agents that have mechanisms other than increasing von Willebrand factor. Regular prophylaxis is seldom required, and treatment is initiated before planned invasive procedures or in response to bleeding.

    Full Text Available In einer Mehrzahl von Abhandlungen über Bašćanska ploča berücksichtigen die Verfasser auch die Sprache, in der Regel kurz, nur in einem oder zwei Sätzen. Die größten Bemühungen sind auf die Rekonstruirung der unlesbaren Teilen gerichtet, dagegen nicht weinger interessanter lesbarer Teil regte eine Sprachanalyse selten an. Gewöhnlich wird festgestellt, daß die Tafel in der kroatischen Sprache geschrieben ist, während die philologisch gut unterrichtete Forscher vermeiden diesartige Nenunngen, indem sie das Vorhandensein der altslawischen und altkroatischen Sprachelemente entdeckten. Man versuchte noch nicht in einer Analyse sprachliche Grundschichte und darauf geschichtete Sprachelemente zu bestimmen. Nach dem ersten Eindruck wurde bestimmt, ob es sich um "die kroatische Srpache mit den Elementen der alten slawischen liturgischen Sprache" handelt oder um "die altslawische in der manche kroatische Spracheigenschaften hereingekommen sind". Die Analyse mancher Spracheinzelheiten (Halblaute und "Jat" weist auf altslawische Grundschicht hin. Der Verfasser hat sich trotzdem nicht entschieden den Fachausdruck "kroatische Redaktion des altslawischen" zu verwenden, weil er neue Analyse und neue Begriffsbestimmungen als nötig hält, wie z.B. "Redaktion", "Rezension" usw, um mit Sicherkeit sagen zu können, ob es um kroatische Redaktion des altslawischen oder um andere Formen der altslawischen - alt kroatischen Interferenz geht.

  19. The cross-bridge dynamics is determined by two length-independent kinetics: Implications on muscle economy and Frank-Starling Law.

    2016-01-01

    The cellular mechanisms underlying the Frank-Starling Law of the heart and the skeletal muscle force-length relationship are not clear. This study tested the effects of sarcomere length (SL) on the average force per cross-bridge and on the rate of cross-bridge cycling in intact rat cardiac trabeculae (n=9). SL was measured by laser diffraction and controlled with a fast servomotor to produce varying initial SLs. Tetanic contractions were induced by addition of cyclopiazonic acid, to maintain a constant activation. Stress decline and redevelopment in response to identical ramp shortenings, starting at various initial SLs, was analyzed. Both stress decline and redevelopment responses revealed two distinct kinetics: a fast and a slower phase. The duration of the rapid phases (4.2 ± 0.1 msec) was SL-independent. The second slower phase depicted a linear dependence of the rate of stress change on the instantaneous stress level. Identical slopes (70.5 ± 1.6 [1/s], p=0.33) were obtained during ramp shortening at all initial SLs, indicating that the force per cross-bridge and cross-bridge cycling kinetics are length-independent. A decrease in the slope at longer SLs was obtained during stress redevelopment, due to internal shortening. The first phase is attributed to rapid changes in the average force per cross-bridge. The second phase is ascribed to both cross-bridge cycling between its strong and weak conformations and to changes in the number of strong cross-bridges. Cross-bridge cycling kinetics and muscle economy are length-independent and the Frank-Starling Law cannot be attributed to changes in the force per cross-bridge or in the single cross-bridge cycling rates.

    Frank-Ter Haar syndrome (FTHS) is an autosomal-recessive disorder characterized by skeletal, cardio-vascular, and eye abnormalities, such as increased intraocular pressure, prominent eyes, and hypertelorism. The most common underlying genetic defect in Frank-Ter Haar syndrome appears to be due to mutations in the SH3PXD2B gene on chromosome 5q35.1. Until now, only six mutations in SH3PXD2B gene have been identified. A genetic heterogeneity of FTHS was suggested in previous studies. FTHS was suspected clinically in a girl of 2years old, born from non-consanguineous Moroccan healthy parents. The patient had been referred to a medical genetics outpatient clinic for dysmorphic facial features. Whole Exome Sequencing (WES) was performed in the patient and her parents, in addition to Sanger sequencing that was carried out to confirm the results. We report the first description of a Moroccan FTHS patient with two novel compound heterozygous mutations c.806G>A; p.Trp269* (maternal allele) and c.892delC; p.Asp299Thrfs*44 (paternal allele) in the SH3PXD2B gene. Sanger sequencing confirmed this mutation in the affected girl and demonstrated that her parents carry this mutation in heterozygous state. Our results confirm the clinical diagnosis of FTHS in this reported family and contribute to expand the mutational spectrum of this rare disease. Our study shows also, that exome sequencing is a powerful and a cost-effective tool for the diagnosis of a supposed genetically heterogeneous disorder such FTHS. Copyright © 2017 Elsevier B.V.

    Dienones obtained from the facile dearomatization of phenols, can be further transformed to semi-benzenes prone to rearomatize in clean, but sometimes unexpected, fashion. Over a hundred years ago, K. von Auwers found that adding Grignards on dienones would lead spontaneously to subsequent dehydration and a novel aromatizing rearrangement. This reaction was ignored for 50 years before Melvin Newman re-investigated these findings, studied the mechanism, and developed variations on the same theme. Since then, despite the tremendous potential of the reactions, those studies were only rarely mentioned, before finally falling into oblivion. This review aims to provide the reader with a detailed history and comprehensive bibliography of the von Auwers rearrangement, some of its synthetic applications, and new unpublished material in the hope to open new perspectives on this forgotten reaction.

    Full Text Available Article in German,Abstracts in English, German and Spanish. Focussing Alexander von Humboldt's Vues des Cordillères et Monumens des peuples indigènes de l'Amérique (1810 - 1813 in the context of his monumental work, this essay tries to highlight not only the creation of a new discourse on the Americas but, at the same time, the project(ion of a new order of world cultures. From a transregional perspective, Humboldt's aesthetically most radical book can be fully understood as a musée imaginaire of world cultures whose spatial, temporal, social, literary, frictional, architextual and cultural dimensions allow new insights in one of the most fascinating texts of the early 19th century. Alexander von Humboldt's Vues are creating a transmedial kaleidoscope within a fractal vision of the cultures of the world in the second period of accelerated globalization.

    Full Text Available Two litters of Germanshepherd dogs were evaluated for a haemorrhagic tendency that was characterised by excessive bleeding from the umbilicus at birth, haemorrhage and haematoma formation at vaccination, excessive bruising, and lameness due to haemarthrosis. Platelet counts, clotting times and Von Willebrand's factor (VWF assays were assessed in all dogs. Factor VIII determination was performed in 1 puppy and its parents. Based on the clotting times and VWF assay, 6 puppies (4 male and 2 female showed type I Von Willebrand's disease (VWD, 5 (4 male and 1 female possible type II VWD, and 4 were unaffected. One puppy with possible type II VWD had very low factor VIII activity; its sire had a normal factor activity, whereas the dam was in the low-normal range. This article reports type I and possible type II VWD in 2 related litters of German shepherd dogs, the latter being rare in German shepherd dogs.

    Das Hauptanliegen des Papiers ist, ein Paradigma für Probleme mit neuartigen Integrationsanforderungen für Forschung und Entwicklung in verteilten eingebetteten Echtzeitsystemen zu motivieren und vorzustellen, nämlich den Begriff Cyber-Physical Systems. Bei einer in letzter Zeit stark zunehmenden Anzahl von Realzeitanwendungen können ohne die Berücksichtigung solcher Forderungen keine praktisch brauchbaren Lösungen erwartet werden. Einige Anwendungsfelder werden angesprochen. Im Einzelnen werden dann für Elektroautos, die mit erneuerbaren Energien betrieben werden sollen, einerseits die Management-, verteilte Verhandlungs- und Verteilungsprobleme der benötigten Energie in einem bottom-up Ansatz gelöst. Andererseits wird als Teil unserer Projektarbeit die Bereitstellung von Reserveenergie für den allgemeinen Bedarf durch Autobatterien vorgestellt. Es zeigt sich, dass dies effizienter und wesentlich kurzfristiger in unserem verteilten Vorgehen geschehen kann als in traditionellen Verfahren.

    Portal hypertension is the most common complication of cirrhosis of the liver and leads to a reversal of blood flow and re-opening of pre-formed portal-systemic collaterals. Amongst a variety of possible hepato-fugal collaterals, the Cruveilhier-von Baumgarten syndrome, consisting of the reopening of umbilical veins, is a rare variant. It has been possible to demonstrate this clearly by sonography in 18 patients.

  8. Baron von Zach's business relations with the Munich entrepreneur Joseph von Utzschneider (German Title: Geschäftsbeziehungen des Barons von Zach zu dem Münchner Unternehmer Joseph von Utzschneider)

    Science.gov (United States)

    Schneider, Ivo

    The relationship between the astronomer von Zach on the one side and the entrepreneur Joseph von Utzschneider and his partner Georg von Reichenbach on the other dates presumably from the year 1807 when Zach spent two months in Munich. Already in the same year Zach had ordered an instrument for himself and began to solicit business for the institute of Reichenbach, Utzschneider, and Liebherr, which was founded in 1804. One of the clients canvassed by Zach was the director of the observatory in Naples Zuccari. Zuccari had ordered the whole equipment for the new observatory from this institute in 1813. The instruments for Naples, which were completed in 1814, were sent accompanied by Reichenbach by land and sea to their destination where Reichenbach supervised their setup. At that time Reichenbach had separated from Utzschneider who kept the optical institute in Benediktbeuern with his new partner Joseph von Fraunhofer whereas Reichenbach became owner of the mathematical-mechanical institute in Munich. For personal and economical reasons Utzschneider began soon after to produce not only optical glass but also optical devices similar to those offered by Reichenbach. As soon as two institutes in Munich competed against each other on the market for sophisticated geodetical and astronomical instruments Zach sided with Utzschneider. Zach's main professional argument for this decision was that both competitors got the optical glass for their instruments from Utzschneider's optical institute in Benediktbeuern. This meant that Utzschneider had first choice and so the optical part of his instruments could be considered as better than that of Reichenbach`s instruments. Zach's role as an agent in Italy and France for the sale of products coming from Utzschneider's manufactories is highlighted by three of Zach's letters to Utzschneider from 1817 and 1818, two of which are reproduced here for the first time.

    Full Text Available Krankheitsbedingte Artefakte können bei der SpA (Spondylitis ankylosans; Mb. Bechterew die Sensitivität einer Knochendichtemessung im Lumbalbereich beeinträchtigen. Das bei dieser rheumatischen Erkrankung bekannte Osteoporoserisiko ist neben genetischen Faktoren und Entzündungsmechanismen auch von verschiedenen exogenen Einflüssen abhängig. An 47 SpA-Patienten wurde mittels DEXA eine vergleichende Knochendichtemessung (BMD an der Hüfte (Schenkelhals und Ward'sches Dreieck sowie im Bereich der Wirbelsäule (L1-L4 vorgenommen. Zusätzlich erfolgte eine Erhebung der Lebens-Ernährungsgewohnheiten der SpA-Patienten in bezug auf die BMD, um exogene Einflüsse erfassen zu können. Die Knochendichtemessungen ergaben an der LWS wesentlich häufiger eine BMD im Normbereich als am proximalen Femur. Besonders deutliche Unterschiede traten im höheren Lebensalter auf, bei dem aufgrund von Kalzifizierungsvorgängen und Syndesmophyten an der LWS fälschlicherweise eine Dichtezunahme vorgetäuscht wird. Es kann daher bei SpA empfohlen werden, die wesentlich sensitivere Dichtemessung am Schenkelhals durchzuführen. Die über einen Zeitraum von 3 Jahren beobachteten, signifikant erhöhten, medianen CRP-Spiegel zeigen, daß eine permanente Aktivierung von Entzündungsprozessen bei SpA auch einen negativen Faktor betreffend des Knochenmasseverlustes darstellt. Die Analyse der Lebensgewohnheiten ergab, daß SpA-Patienten mit normaler BMD ausnahmslos regelmäßig kalziumreiche Nahrungsmittel zu sich nehmen; bei verminderter BMD wurde in der Mehrheit ein fehlender Konsum an Milchprodukten beobachtet. Leider war auch mit abnehmender BMD eine Verminderung der bei SpA empfohlenen Bewegungsübungen festzustellen. Aufgrund der Resultate ergibt sich eine generelle Empfehlung zu regelmäßigen Bewegungsübungen plus Osteoporosediät bei allen Bechterew-Patienten.

    Local operations with classical communication (LOCC) and separable operations are two classes of quantum operations that play key roles in the study of quantum entanglement. Separable operations are strictly more powerful than LOCC, but no simple explanation of this phenomenon is known. We show that, in the case of von Neumann measurements, the ability to interpolate measurements is an operational principle that sets apart LOCC and separable operations

    Despite his conviction on a morals charge involving a boy, the early German Social Democrat Johann Baptist von Schweitzer went on to have a successful political career. His life furnishes the context to present remarks by his political opponents Marx and Engels, which reveal their deep-seated homophobia.

    1999-07-01

    The use of package units in pharmaceutical plants is increasing. If they are involved in the manufacture of pharmaceuticals and have an influence on the quality of the end product, the user is required to validate the processes used. Parallel to the growing demands with respect to the automation of these units, the importance of PCS equipment has increased and with this the necessity for its qualification. Experience to date shows that the manufacturer's awareness of these requirements can be heightened still further. This paper describes approaches for improving the present situation and should be interpreted not as criticism but as providing an opportunity to increase the knowledge base and work together to define solutions which satisfy the guidelines. (orig.) [German] Der Einsatz von Package Units in Pharma-Anlagen erfaehrt zunehmende Verbreitung. Wenn sie an der Herstellung von Arzneimitteln beteiligt sind und auf die Qualitaet des Endprodukts Einfluss nehmen, unterliegen sie der Validierungspflicht, die der Anwender zu gewaehrleisten hat. Entsprechend den wachsenden Anforderungen an die Automatisierung dieser Einheiten ist auch der Stellenwert der PLT-Ausruestung angestiegen und mit ihm die Notwendigkeit von deren Qualifizierung. Die bisherige Praxis zeigt, dass die Sensbilitaet der Hersteller diesen Anforderungen gegenueber noch besser entwickelt werden kann. Der Beitrag zeigt Wege auf, um die derzeitige Situation zu verbessern und sollte nicht als Kritik sondern als Chance aufgefasst werden, den Wissensstand auszugleichen und gemeinsam zu richtliniengerechten Loesungen zu kommen.

    Full Text Available Acquired von Willebrand syndrome (AVWS is an uncommon, underdiagnosed, and heterogeneous disease which is increasingly recognized as a cause of bleeding diatheses. Systemic lupus erythematosus (SLE is an infrequent cause of AVWS. Herein, we report a case of AVWS diagnosed during the initial presentation of SLE in a previously healthy young man with no family history of bleeding diathesis who presented with worsening epistaxis, gastrointestinal bleeding, and anasarca. He was found to have severe anemia and prolonged activated partial thromboplastin time (aPTT with severely decreased levels of von Willebrand factor (VWF measurements in addition to markedly decreased factor VIII levels. Further evaluation revealed nephrotic syndrome and interstitial lung disease due to SLE. He initially received combination therapy with intravenous immunoglobulin (IVIG and von Willebrand factor/factor VIII concentrates without significant improvement. Treatment with steroids, cyclophosphamide, and rituximab was followed by clinical improvement evidenced by cessation of bleeding. The short follow-up did not allow us to definitely prove the therapeutic effect of immunosuppressive treatment on AVWS in SLE patients. This case adds to the literature supporting the relationship between AVWS and SLE and highlights the importance of combination therapy in the treatment of severe AVWS as well as the role of IVIG, cyclophosphamide, and rituximab in AVWS associated with SLE.

    To assess compliance with a periodic surveillance regimen for Von Hippel-Lindau disease. In this nationwide study, Von Hippel-Lindau disease mutation carriers and those at 50% risk were invited to complete a questionnaire assessing (compliance with) advice given for periodic surveillance. Medical record data on compliance with recommended radiologic surveillance examinations were also collected. Of the 84 (77%) participants, 78 indicated having received advice to undergo periodic surveillance. Of these, 71 reported being fully compliant with that advice. In 64% of the cases, this advice was only partially consistent with published guidelines. Based on medical record data, between one quarter and one third of individuals did not undergo surveillance as recommended in the guidelines for central nervous system lesions and one half for visceral lesions. Screening delay for central nervous system lesions was significantly higher in one hospital and in those cases where "the advice given" deviated from the guidelines. The majority of those with or at risk of Von Hippel-Lindau disease reported having received and being fully compliant with screening advice. However, in many cases, the advice given was only partially consistent with published guidelines, and screening delays were observed. Efforts should be undertaken to stimulate guideline-based surveillance advice and to minimize screening delay.

  15. On the problem of completeness of QM: von Neumann against Einstein, Podolsky, and Rosen

    OpenAIRE

    2008-01-01

    We performed a comparative analysis of the arguments of Einstein, Podolsky and Rosen -- EPR, 1935 (against the completeness of QM) and the theoretical formalism of QM (due to von Neumann, 1932). We found that the EPR considerations do not match at all with the von Neumann's theory. Thus EPR did not criticize the real theoretical model of QM. The root of EPR's paradoxical conclusion on incompleteness of QM is the misuse of von Neumann's projection postulate. EPR applied this postulate to obser...

    For realistic numerical simulations of the stress-strain behaviour of structures, models are necessary which describe elastic-inelastic and scattering material behaviour. The developed models simulate elastic, viscoplastic and anisotropic damage material phenomena. An approach is proposed for covering stochastic material beahviour by correspondingly distributed parameters of the deterministic material model. Numerical simulations of biaxial material tests and structural tests demonstrate the range of applicability. (orig.) [German] Die realitaetsnahe numerische Simulation des Spannungs-Verformungsverhaltens von Bauteilen erfordert Modelle zur Beschreibung inelastischen und streuenden Materialverhaltens.

Desweiteren wird ein Konzept vorgestellt, mit dem streuendes Materialverhalten mit streuenden Materialparametersaetzen deterministischer Stoffmodelle beschreibbar ist. Numerische Simulationen von Werkstoff- und Bauteilversuchen veranschaulichen den Anwendungsbereich der Modelle. (orig.)

    Von Willebrand Disease (VWD) is the most common human inherited bleeding disorder due to a defect of Von Willebrand Factor (VWF), which a glycoprotein crucial for platelet adhesion to the subendothelium after vascular injury. VWD include quantitative defects of VWF, either partial (type 1 with VWF levels < 50 IU/dL) or virtually total (type 3 with undetectable VWF levels) and also qualitative defects of VWF (type 2 variants with discrepant antigenic and functional VWF levels). The most bleeding forms of VWD usually do not concern type 1 patients with the mildest VWF defects (VWF levels between 30 and 50IU/dL). Von willebrand factor is a complex multimeric protein with two functions: it forms a bridge between the platelets and areas of vascular damage and it binds to and stabilizes factor VIII, which is necessary for the clotting cascade. By taking a clinical history of bleeding (mucocutaneous bleeding symptoms suggestive of a primary haemostatic disorder, a quantitative or qualitative abnormality of VWF is possible) it is important to think about VWD and to make the appropriate diagnosis. If the VWD is suspected diagnostic tests should include an activated partial thromboplastin time, bleeding time, factor VIII: C Ristocetin cofactor and vWF antigen. Additional testing of ristocetin induced plattlet adhesion (RIPA) the multimeric structure and collagen binding test and genanalysis allow diagnosing the different types of von. Willebrand Disease. The treatment of choice in mild forms is the synthetic agent desmopressin. In patients with severe type 1, type 2B, 2N and type 3 or in people who do not response to desmopressin, the appropriate treatment is a factor VIII concentrate that is rich of VWF. We report a case of infant in 27-month-old boy who had been referred due to haemorrhagic shock. His birth histories, his familie's social history and developmental milestones were unremarkable. He was born at full term with no antenatal or perinatal complications. Prior to

    During the evaluation of ultrasonic images, e.g. SAFT-reconstructed B-scan images (SAFT=Synthetic Aperture Focusing Technique) it is often difficult to decide, what is the origin of reconstructed image points: were they caused by defects, specimens geometry or mode-conversions. To facilitate this evaluation a tool based on the comparison of data was developed. Different kinds of data comparison are possible: identification of that RF-signals, which caused the reconstructed image point. This is the comparison of a reconstructed image with the corresponding RF-data. Comparison of two reconstructed images performing a superposition using logical operators. In this case e.g. the reconstruction of an unknown reflector is compared with that of a known one. Comparison of raw-RF-data by simultaneous scanning through two data sets. Here the echoes of an unknown reflector are compared with the echoes of a known one. The necessary datasets of known reflectors may be generated experimentally on reference reflectors or modelled. The aim is the identification of the reflector type, e.g. cracklike or not, the determination of position, size and orientation as well as the identification of accompanying satellite echoes. The interpretation of the SAFT-reconstructed B-scan image is carried out by a complete description of the reflector. In addition to the aim of interpretation the tool described is well suited to educate and train ultrasonic testers. (orig./MM) [Deutsch] Bei der Auswertung von Ultraschall-Abbildungen, z.B.

Um diese Auswertung zu erleichtern, wurde ein Werkzeug entwickelt, welches auf dem Vergleich von Datensaetzen basiert.

    Full Text Available Zur Klaerung der Frage, ob der Begriff "Kinoplasma" fuer gewisse, von MERTON (1924,1926, 1930 beobachtete Bildungen an den reifenden Spermiden von pulmonaten Mollusken oder fuer Bestandteile des Cytoplasmas im Sinne von STRASBURGER und SCARTH zu verwenden ist, werden in der vorliegenden Mitteilung die Vorgaenge bei der Spermiohistogenese von Australorbis glabratus olivaceus untersucht. Es ergibt sich: 1. Das von MERTON bezeichnete "Kinoplasma" existiert nicht als solches, es handelt sich bei den von ihm dargestellten Protoplasmabildungen um kugelige, von den Spermiden abgeschnuerte Restkoerper nicht verwendeten Baumaterials, bestehend aus Protoplasma und einigen Mitochondrien. Sie werden von den Naehr- oder Bazalzellen phagozytiert. Der Ausdruck "Kinoplasma" kann nur fuer die submikroskopischen, geformten, faedigen Elemente des Cytoplasmas reserviert bleiben, die den geradlinigen Fall der uebrigen nicht geformten Komponenten bremst oder ablenkt; damit muss das Kinoplasma aber aus dem Begriff des Cytoplasmas herausgenommen werden, da es, wenn auch vermutlich reversibel, eine Differenzierung darstellt. 2. Der Spermienfaden wird von den Centriolen (Axialfilament und den Mitochondrien (zwei peripher gelegene Spiralfilamente, sowie einem Plasmamantel gebildet. 3. Nach Beendigung des Auswachsens der Spermiengeissel, die zu diesem Zeitpunkt nur aus dem Achsenfaden und dem Protoplasmazylinder besteht, setzt sich eine Protoplasmamasse vom Kopf in Richtung zum Geisselende in Bewegung. Sie fuehrt den Golgi-Koerper und sehr viele Mitochondrien mit sich. Aus diesen entwickeln sich Fibrillen, die sich zu den beiden Spiralfilamenten zusammenfuegen. Diese Masse entspricht der von MERTON in seiner Theorie als Kinoplasma bezeichneten Komponente. 4. Die Bewegung dieses Protoplasmateils wird auf den Schub zurueckgefuehrt, den die sich bildenden Fibrillen auf die Mitochondrien ausueben. 5.

    Full Text Available The article presents Heinrich von Wlislocki – a folklorist, literary historian, linguist and educator, wide ly known in the scientific circles of Europe of the late XIX century, as one of the first XIX century European researcher of the gypsies – in the memories of his contemporaries. He was a Doctor of Philosophy, one of those whom his colleagues called a “friend of the Gypsies”, he went to wander with the camp of Transylvanian gypsies to collect field material directly in their midst. As a result, about 80 papers were published in selected publications, as well as in well-known scientific journals in Europe. Most often, his publications could be seen in the Journal of the Gypsy Lore Society, of which he was a member. Being a contemporary of George Henry Borrow (1803–1881, Alexander Gheorghe Paspati (1814–1891, Charles Godfrey Leland (1824–1903, Francis Hindes Grum (1851–1902, Anton Herrmann (1851–1926, Hans Ferdinand Helmolt (1865–1929, Heinrich von Wlislocki (1856–1907 was one of the few folklorists and connoisseurs of Gypsy life and culture of the XIX century. The latter completely immersed themselves in the life of the Gypsy, mastering for the first time the ethnographic method of included observation. It was a heroic period of studying folklore in Europe, when dedicated scientists created a folkloric field of research from the scratch. 110 years passed since the death of Heinrich von Wlislocki but this did not erase his name from the historical memory, folklorist researchers still refer to his works, including them in scientific circulation.

  3. Von Willebrand factor regulation of blood vessel formation.

    Science.gov (United States)

    Randi, Anna M; Smith, Koval E; Castaman, Giancarlo

    2018-06-04

    Several important physiological processes, from permeability to inflammation to haemostasis, take place at the vessel wall and are regulated by endothelial cells (EC). Thus, proteins that have been identified as regulators of one process are increasingly found to be involved in other vascular functions. Such is the case for Von Willebrand Factor (VWF), a large glycoprotein best known for its critical role in haemostasis. In vitro and in vivo studies have shown that lack of VWF causes enhanced vascularisation, both constitutively and following ischemia. This evidence is supported by studies on blood outgrowth endothelial cells (BOEC) from patients with lack of VWF synthesis (type 3 von Willebrand disease [VWD]). The molecular pathways are likely to involve VWF binding partners, such as integrin αvβ3, and components of Weibel Palade bodies (WPB), such as Angiopoietin-2 and Galectin-3, whose storage is regulated by VWF; these converge on the master regulator of angiogenesis and endothelial homeostasis, vascular endothelial growth factor (VEGF) signalling. Recent studies suggest that the roles of VWF may be tissue-specific. The ability of VWF to regulate angiogenesis has clinical implications for a subset of VWD patients with severe, intractable gastrointestinal bleeding due to vascular malformations. In this article, we review the evidence showing that VWF is involved in blood vessel formation, discuss the role of VWF high molecular weight multimers in regulating angiogenesis, and the value of studies on BOEC in developing a precision medicine approach to validate novel treatments for angiodysplasia in congenital VWD and acquired von Willebrand syndrome.

  8. Otto von Guericke and 17th century cosmology

    Science.gov (United States)

    Knobloch, Eberhard

    Otto von Guericke's scientific method was based on reason and experimental science. His cosmology was embedded in theology and can be interpreted as a refutation of Descartes' worldview. He used Nicolaus Cusanus' theory of quantities in order to characterize space. The notion of space has to be distinguished from that of world or heaven. Forces play a crucial role in this respect described by Athanasius Kircher in his "Celestial Journey". Guericke read this work very diligently. In spite of some obvious similarities between Guericke's and Newton's scientific aims and methods there are crucial differences between the scientific convictions and results of these scholars.

  11. Inadequacy of von Neumann entropy for characterizing extractable work

    International Nuclear Information System (INIS)

    Dahlsten, Oscar C O; Renner, Renato; Rieper, Elisabeth; Vedral, Vlatko

    2011-01-01

    The lack of knowledge that an observer has about a system limits the amount of work it can extract. This lack of knowledge is normally quantified using the Gibbs/von Neumann entropy. We show that this standard approach is, surprisingly, only correct in very specific circumstances. In general, one should use the recently developed smooth entropy approach. For many common physical situations, including large but internally correlated systems, the resulting values for the extractable work can deviate arbitrarily from those suggested by the standard approach.

    2008-01-01

    Von Neumann's continuous geometry has been considerably developed by Connes and is characterized by two fundamental concepts. First it is formulated without any direct reference to points and second it possesses a dimensional function. The present work explores the relevance of these two points to string theory as well as E-infinity theory. In particular we show that point-lessness and dimensional function implies fractality. In turn fractality leads to the concept of average or fuzzy symmetry and the elimination of gauge anomalies

    2009-01-01

    Let σ be a surjective ultraweakly continuous *-linear mapping and d be a σ-derivation on a von Neumann algebra. We show that there are a surjective ultraweakly continuous *-homomorphism and a Σ-derivation such that D is ultraweakly continuous if and only if so is d. We use this fact to show that the σ-derivation d is automatically ultraweakly continuous. We also prove the converse in the sense that if σ is a linear mapping and d is an ultraweakly continuous *-σ-derivation, then there is an ultraweakly continuous linear mapping such that d is a *-Σ-derivation

    We obtain the von Neumann entropy per state of the Haldane exclusion statistics with parameter g in terms of the mean occupation number bar n{wlnw-(1+w)ln(1+w)}, where w=(1-bar n). This reduces correctly to the well known expressions in the limiting cases of Bose (g=0) and Fermi (g=1) statistics. We have derived the second and third order fluctuations in the occupation numbers for arbitrary g. An elegant general duality relationship between the w factor associated with the particle and that associated with the hole at the reciprocal g is deduced along with the attendant relationship between the two respective entropies

  8. Effects of stacking fault energies on the interaction between an edge dislocation and an 8.0-nm-diameter Frank loop of self-interstitial atoms

    Directory of Open Access Journals (Sweden)

    S. Hayakawa

    2016-12-01

    Full Text Available Molecular dynamics simulations were conducted to investigate the effects of stacking fault energy (SFE as a single variable parameter on the interaction between an edge dislocation and a Frank loop of self-interstitial atoms with a diameter of 8.0nm. The physical contact between the edge dislocation and the loop causes constriction of the edge dislocation, followed by the formation of a D-Shockley partial dislocation. The latter process is associated with either the formation of a screw component and its cross-slip, or the direct core reaction between the dislocation and the loop. These processes induce either the absorption of the loop into the dislocation or the transformation of the loop into a perfect loop. The SFE influences the interaction morphologies by determining the separation distance of the two partial dislocations and consequently the rate of constriction. The dependence of the interaction morphology on the SFE varies with the habit plane of the loop. A higher SFE increases the probability of the absorption or transformation interaction; however, only loop shearing is observed at the lower limit of the SFE range of austenitic stainless steels.

    2002-01-01

    There is a gradient of diabetes prevalence among populations of the African Diaspora, with a rate of about 1% in West Africa, 12% in Jamaica and 16% in the United States. A population-based survey was conducted in an urban community in Jamaica to document the risk factors for the evolution of impaired glucose tolerance to frank diabetes. In a sample of 614 adults, 239 men and 375 women, oral glucose tolerance tests and examinations were conducted at Baseline and after 4-years of Follow-Up. There were significant increases in virtually all weight and adiposity variables for both men and women. Energy expenditure was also measured in a subset of participants at Follow-Up and was related significantly to glucose tolerance status. Among men, baseline age, weight, fat mass, body fat, waist circumference, and change in waist circumference were predictive of worsening glucose tolerance status. Among women, only age and change in waist circumference was a significant predictor. No physical activity parameter was predictive of change in tolerance status. These results provide support for the need to decrease adiposity as an important mechanism to control the rise in diabetes prevalence. (author)

    Plasmatic concentrations of von Willebrand Factor (vWF) increase during pregnancy in humans and dogs; however the mechanism of such increase is still not well defined. The aims of this study were: (i) to evaluate changes in vWF concentration during pregnancy and during the subsequent oestrous cycle in bitches affected and unaffected by von Willebrand Disease (vWD); (ii) to correlate the vWF levels and cortisol levels in both groups. Seven vWD affected (GI) and nine unaffected (GII) bitches were used. The animals were assessed during pregnancy, parturition, lactation and non-gestational oestrous cycle in 11 moments (Pregnancy 1, Pregnancy 2, Parturition, Lactation 1, Lactation 2, Lactation 3, Anestrus, Proestrus, Oestrus, Diestrus 1, and Diestrus 2). The following tests were performed; measurement of von Willebrand factor antigen (vWF:Ag), albumin and cortisol. In both groups, vWF concentration remained stable during the non-gestational oestrous cycle, but increased during pregnancy, with the highest value observed at parturition. Increases of 70% and 124% in vWF were seen in GI and GII, respectively, compared to anestrus. No correlation was found between vWF and cortisol. Values of vWF:Ag changed during pregnancy, with a peak at parturition, both in vWD affected and unaffected animals. Values of vWF were not altered in the different phases of the oestrous cycle following pregnancy in both groups. Evaluation of vWF during pregnancy can cause false negative results for vWD, but assessment can be performed at any point in the oestrous cycle of non-pregnant bitches. © 2012 Blackwell Verlag GmbH.

    Lanke, Elsa; Kristoffersson, Ann-Charlotte; Philips, Malou

    2008-01-01

    von Willebrand factor (VWF) is a plasma protein that consists of a series of multimers of which the high-molecular-weight VWF multimers are the most potent in platelet adhesion and aggregation. The propeptide of the VWF (VWFpp) is known to be essential in the process of multimer assembly. Genetic...... mutation in the VWFpp abolishes multimerization of VWF. The mutation probably disrupts the normal configuration of the VWFpp, which is essential for correct orientation of the protomers and ultimately multimerization. The mutant amino acid is located in a region that is highly conserved across several...

    In the winter of 1943-1944, Jung had suffered a coronary thrombosis which almost cost him his life. During his illness, Jung experienced a series of visions, described in his Memories, Dreams, Reflections, which were also to influence significantly the development of his theoretical thinking. On 27(th) September 1944, Alwine von Keller (1878-1965) paid a visit to Jung, while he was still convalescing, in Zurich and documented her meeting with him in a series of notes, recently discovered, which testify to the fact that, at the time of their meeting, Jung was engaged in writing the 'Salt' chapter of Mysterium coniunctionis and investigating the alchemistic symbolism of the 'sea'. This theme seems to testify to a continuity of interests on Jung's part with the seminar he held at Eranos the previous year on the cartographic art of Opicinus de Canistris (1296-c.1352). With its addition of many unpublished details, Alwine von Keller's notes supplement the report which Jung made of his visions experienced during his sickness in MDR. In particular, these attest to the fact that Jung had attributed the terrible experience which he had endured to the problem of the conjunctio, which was confronting him from the theoretical point of view in his writing of Mysterium coniunctionis. © 2011, The Society of Analytical Psychology.

The tumors of the central nervous system (CNS are benign and are comprised of a nest of blood vessels and are called hemangioblastomas. Hemangioblastomas may develop in the brain, the retina of the eyes, and other areas of the nervous system. Other types of tumors develop in the adrenal glands, the kidneys, or the pancreas. Symptoms of VHL vary among patients and depend on the size and location of the tumors. Symptoms may include headaches, problems with balance and walking, dizziness, weakness of the limbs, vision problems, and high blood pressure. Cysts (fluid-filled sacs and/or tumors (benign or cancerous may develop around the hemangioblastomas and cause the symptoms listed above. Individuals with VHL are also at a higher risk than normal for certain types of cancer, especially kidney cancer.

  18. von Willebrand factor, Jedi knight of the bloodstream.

    Science.gov (United States)

    Springer, Timothy A

    2014-08-28

    When blood vessels are cut, the forces in the bloodstream increase and change character. The dark side of these forces causes hemorrhage and death. However, von Willebrand factor (VWF), with help from our circulatory system and platelets, harnesses the same forces to form a hemostatic plug. Force and VWF function are so closely intertwined that, like members of the Jedi Order in the movie Star Wars who learn to use "the Force" to do good, VWF may be considered the Jedi knight of the bloodstream. The long length of VWF enables responsiveness to flow. The shape of VWF is predicted to alter from irregularly coiled to extended thread-like in the transition from shear to elongational flow at sites of hemostasis and thrombosis. Elongational force propagated through the length of VWF in its thread-like shape exposes its monomers for multimeric binding to platelets and subendothelium and likely also increases affinity of the A1 domain for platelets. Specialized domains concatenate and compact VWF during biosynthesis. A2 domain unfolding by hydrodynamic force enables postsecretion regulation of VWF length. Mutations in VWF in von Willebrand disease contribute to and are illuminated by VWF biology. I attempt to integrate classic studies on the physiology of hemostatic plug formation into modern molecular understanding, and point out what remains to be learned. © 2014 by The American Society of Hematology.

    With the introduction of multislice CT extensive volumetric data sets can be quickly acquired in high spatial resolution. The high spatial resolution reduces partial volume effects and enables multiplanar reconstructions. Regarding the colorectum this means that the colon can be assessed if the colon is sufficiently cleaned and distended, and that transmural infiltration of colorectal carcinoma and liver metastases can be better detected. T-staging of colon cancer is less important than T-staging of rectal cancer. Based on the higher contrast MRI is superior to CT in T-staging of rectal cancer and in the differentiation between scarring tissue and recurrence of carcinoma. (orig.) [German] Mit Einfuehrung der Mehrschicht-CT lassen sich umfangreiche Volumendatensaetze schnell und mit hoher Aufloesung erfassen. Die hohe raeumliche Aufloesung reduziert Teilvolumeneffekte und ermoeglicht multiplanare Rekonstruktionen. In Bezug auf das Kolorektum bedeutet dies, dass das Kolon bei ausreichender Darmreinigung und -distension gut beurteilbar ist und transmurale Infiltrationen von kolorektalen Karzinomen sowie Lebermetastasen leichter zu erkennen sind.Bei Kolonkarzinomen hat das T-Staging weniger klinische Relevanz als bei Rektumkarzinomen. Aufgrund des hoeheren Kontrasts ist die MRT der CT im T-Staging von Rektumkarzinomen sowie in der Unterscheidungzwischen Narben- und Rezidivtumorgewebe ueberlegen. (orig.)

    The German Rocket Team, also known as the Von Braun Rocket Team, poses for a group photograph at Fort Bliss, Texas. After World War II ended in 1945, Dr. Wernher von Braun led some 120 of his Peenemuende Colleagues, who developed the V-2 rocket for the German military during the War, to the United Sttes under a contract to the U.S. Army Corps as part of Operation Paperclip. During the following five years the team worked on high altitude firings of the captured V-2 rockets at the White Sands Missile Range in New Mexico, and a guided missile development unit at Fort Bliss, Texas. In April 1950, the group was transferred to the Army Ballistic Missile Agency (ABMA) at Redstone Arsenal in Huntsville, Alabama, and continued to work on the development of the guided missiles for the U.S. Army until transferring to a newly established field center of the National Aeronautic and Space Administration (NASA), George C. Marshall Space Flight Center (MSFC).

    2018-06-01

    Full Text Available Publicado em 1992, The Butcher Boy, celebrado romance de Patrick McCabe, logo foi adaptado para o cinema e para o teatro. Em sua forma dramática, intitulada Frank Pig Says Hello, a peça teatraliza as memórias de infância de Frank Pig, ou Piglet, um “menino-porquinho”. A despeito da dimensão trágica dos conflitos existenciais e sociais que modelam a peça de McCabe, sua dramaturgia subverte a conhecida tradição das tragédias e dos dramas sociais por meio da paródia e da ironia, substituindo o pathos trágico por humor e deboche. Fortemente marcada por traços recorrentes na arte pós-moderna, Frank Pig Says Hello apresenta-se como uma peça que, ao desconstruir as formas dramáticas tradicionais, desconstrói também, por via do riso, do sarcasmo e do grotesco, motivos e fatos associados à história da Irlanda, assim como questiona valores hegemônicos da cultura ocidental. O presente estudo analisa a parodização da ação trágica na peça, examinando as relações entre dramaticidade, violência e irreverência estética.

    Von Willebrand disease (VWD) is an inherited bleeding disorder, caused by quantitative (type 1 and 3) or qualitative (type 2) defects in von Willebrand factor (VWF). Gene therapy is an appealing strategy for treatment of VWD because it is caused by a single gene defect and because VWF is secreted into the circulation, obviating the need for targeting specific organs or tissues. However, development of gene therapy for VWD has been hampered by the considerable length of the VWF cDNA (8.4 kb [kilobase]) and the inherent complexity of the VWF protein that requires extensive posttranslational processing. In this study, a gene-based approach for VWD was developed using lentiviral transduction of blood-outgrowth endothelial cells (BOECs) to express functional VWF. A lentiviral vector encoding complete human VWF was used to transduce BOECs isolated from type 3 VWD dogs resulting in high-transduction efficiencies (95.6% ± 2.2%). Transduced VWD BOECs efficiently expressed functional vector-encoded VWF (4.6 ± 0.4 U/24 hour per 106 cells), with normal binding to GPIbα and collagen and synthesis of a broad range of multimers resulting in phenotypic correction of these cells. These results indicate for the first time that gene therapy of type 3 VWD is feasible and that BOECs are attractive target cells for this purpose. PMID:16478886

    Frank-Ter Haar syndrome (FTHS), also known as Ter Haar syndrome, is an autosomal-recessive disorder characterized by skeletal, cardiovascular, and eye abnormalities, such as increased intraocular pressure, prominent eyes, and hypertelorism. We have conducted homozygosity mapping on patients representing 12 FTHS families. A locus on chromosome 5q35.1 was identified for which patients from nine families shared homozygosity. For one family, a homozygous deletion mapped exactly to the smallest region of overlapping homozygosity, which contains a single gene, SH3PXD2B. This gene encodes the TKS4 protein, a phox homology (PX) and Src homology 3 (SH3) domain-containing adaptor protein and Src substrate. This protein was recently shown to be involved in the formation of actin-rich membrane protrusions called podosomes or invadopodia, which coordinate pericellular proteolysis with cell migration. Mice lacking Tks4 also showed pronounced skeletal, eye, and cardiac abnormalities and phenocopied the majority of the defects associated with FTHS. These findings establish a role for TKS4 in FTHS and embryonic development. Mutation analysis revealed five different homozygous mutations in SH3PXD2B in seven FTHS families. No SH3PXD2B mutations were detected in six other FTHS families, demonstrating the genetic heterogeneity of this condition. Interestingly however, dermal fibroblasts from one of the individuals without an SH3PXD2B mutation nevertheless expressed lower levels of the TKS4 protein, suggesting a common mechanism underlying disease causation.

Vor diesem Hintergrund ist zentales Anliegen der Untersuchung, einen übergeordneten Analyserahmen für die Befassung mit Frageformen und Fragefunktionen zu entwickeln, der die Beschreibung von Nachfragen in einer allgemeineren Beschreibung von Interrogationen verortet. Das Besondere von Nachfragen wird darin gesehen, daß es sich um Interrogationen handelt, die auf andere sprachliche Äußerungen Bezug nehmen. Hier sind wiederum verschiedene Mittel zu unterscheiden, die für die Unterscheidung von Echofragen und anderen Nachfragen bestimmend sind. In diesem Zusammenhang wird gezeigt, daß auch der Art der Bezugnahme besondere Bedeutung für die Bestimmung von Nachfrageformen und Nachfragefunktionen zukommt.

    In this study an attempt will be made to discuss the epistemological problems in the theory and practice of modern technical medicine in the writings of Hermann von Helmholz. An inquiry into the relationship between von Helmholtz' thinking and the critical philosophy of Immanuel Kant is followed by the characteristics of von Helmholtz' philosophy of science which he himself called "empirical theory". The question of medicine as a science finally leads to the main problem of medical epistemology, viz., the relationship between theoretical knowledge and practice in medicine. In this context the anthropological dimension is brought into consideration.
