  5. The Disappearing Fourth Wall: John Marburger, Science Policy, and the SSC

    John H. Marburger (1941-2011) was a skilled science administrator who had a fresh and unique approach to science policy and science leadership. His posthumously published book Science Policy up Close contains recollections of key science policy episodes in which he participated or observed closely. One was the administration of the Superconducting Supercollider (SSC); Marburger was Chairman of the Universities Research Association, the group charged with managing the SSC, from 1988-1994. Many accounts of the SSC saga attribute its demise to a combination of transitory factors: poor management, rising cost estimates, the collapse of the Soviet Union and thus of the Cold War threat, complaints by ``small science'' that the SSC's ``big science'' was consuming their budget, Congress's desire to cut spending, unwarranted contract regulations imposed by the Department of Energy (DOE) in response to environmental lapses at nuclear weapons laboratories, and so forth. Marburger tells a subtler story whose implications for science policy are more significant and far-reaching. The story involves changes in the attitude of the government towards large scientific projects that reach back to management reforms introduced by the administration of Presidents Johnson, Nixon, and Carter in the 1960s and 1970s. This experience impressed Marburger with the inevitability of public oversight of large scientific projects, and with the need for planners of such projects to establish and make public a cost and schedule tracking system that would model the project's progress and expenditures.

  6. Optimized universal color palette design for error diffusion

    Kolpatzik, Bernd W.; Bouman, Charles A.

    1995-04-01

    Currently, many low-cost computers can only simultaneously display a palette of 256 color. However, this palette is usually selectable from a very large gamut of available colors. For many applications, this limited palette size imposes a significant constraint on the achievable image quality. We propose a method for designing an optimized universal color palette for use with halftoning methods such as error diffusion. The advantage of a universal color palette is that it is fixed and therefore allows multiple images to be displayed simultaneously. To design the palette, we employ a new vector quantization method known as sequential scalar quantization (SSQ) to allocate the colors in a visually uniform color space. The SSQ method achieves near-optimal allocation, but may be efficiently implemented using a series of lookup tables. When used with error diffusion, SSQ adds little computational overhead and may be used to minimize the visual error in an opponent color coordinate system. We compare the performance of the optimized algorithm to standard error diffusion by evaluating a visually weighted mean-squared-error measure. Our metric is based on the color difference in CIE L*AL*B*, but also accounts for the lowpass characteristic of human contrast sensitivity.

    The food and beverage industry is seeking to broaden the palette of naturally derived colorants. Although considerable effort has been devoted to the search for new blue colorants in fruits and vegetables, less attention has been directed toward blue compounds from other sources such as bacteria and fungi. The current work reviews known organic blue compounds from natural plant, animal, fungal, and microbial sources. The scarcity of blue-colored metabolites in the natural world relative to metabolites of other colors is discussed, and structural trends common among natural blue compounds are identified. These compounds are grouped into seven structural classes and evaluated for their potential as new color additives.

    Coral reefs are colored by eukaryotic chromoproteins (CPs) that are homologous to green fluorescent protein. CPs differ from fluorescent proteins (FPs) by intensely absorbing visible light to give strong colors in ambient light. This endows CPs with certain advantages over FPs, such as instrument-free detection uncomplicated by ultra-violet light damage or background fluorescence, efficient Förster resonance energy transfer (FRET) quenching, and photoacoustic imaging. Thus, CPs have found utility as genetic markers and in teaching, and are attractive for potential cell biosensor applications in the field. Most near-term applications of CPs require expression in a different domain of life: bacteria. However, it is unclear which of the eukaryotic CP genes might be suitable and how best to assay them. Here, taking advantage of codon optimization programs in 12 cases, we engineered 14 CP sequences (meffRed, eforRed, asPink, spisPink, scOrange, fwYellow, amilGFP, amajLime, cjBlue, meffBlue, aeBlue, amilCP, tsPurple and gfasPurple) into a palette of Escherichia coli BioBrick plasmids. BioBricks comply with synthetic biology's most widely used, simplified, cloning standard. Differences in color intensities, maturation times and fitness costs of expression were compared under the same conditions, and visible readout of gene expression was quantitated. A surprisingly large variation in cellular fitness costs was found, resulting in loss of color in some overnight liquid cultures of certain high-copy-plasmid-borne CPs, and cautioning the use of multiple CPs as markers in competition assays. We solved these two problems by integrating pairs of these genes into the chromosome and by engineering versions of the same CP with very different colors. Availability of 14 engineered CP genes compared in E. coli , together with chromosomal mutants suitable for competition assays, should simplify and expand CP study and applications. There was no single plasmid-borne CP that combined

    In the rapidly developing specialty of palliative care, literature reviews have become increasingly important to inform and improve the field. When applying widely used methods for literature reviews developed for intervention studies onto palliative care, challenges are encountered such as the heterogeneity of palliative care in practice (wide range of domains in patient characteristics, stages of illness and stakeholders), the explorative character of review questions, and the poorly defined keywords and concepts. To overcome the challenges and to provide guidance for researchers to conduct a literature search for a review in palliative care, Palliative cAre Literature rEview iTeraTive mEthod (PALLETE), a pragmatic framework, was developed. We assessed PALETTE with a detailed description. PALETTE consists of four phases; developing the review question, building the search strategy, validating the search strategy and performing the search. The framework incorporates different information retrieval techniques: contacting experts, pearl growing, citation tracking and Boolean searching in a transparent way to maximize the retrieval of literature relevant to the topic of interest. The different components and techniques are repeated until no new articles are qualified for inclusion. The phases within PALETTE are interconnected by a recurrent process of validation on 'golden bullets' (articles that undoubtedly should be part of the review), citation tracking and concept terminology reflecting the review question. To give insight in the value of PALETTE, we compared PALETTE with the recommended search method for reviews of intervention studies. By using PALETTE on two palliative care literature reviews, we were able to improve our review questions and search strategies. Moreover, in comparison with the recommended search for intervention reviews, the number of articles needed to be screened was decreased whereas more relevant articles were retrieved. Overall, PALETTE

  16. Interactive multi-objective path planning through a palette-based user interface

    n a problem where a human uses supervisory control to manage robot path-planning, there are times when human does the path planning, and if satisfied commits those paths to be executed by the robot, and the robot executes that plan. In planning a path, the robot often uses an optimization algorithm that maximizes or minimizes an objective. When a human is assigned the task of path planning for robot, the human may care about multiple objectives. This work proposes a graphical user interface (GUI) designed for interactive robot path-planning when an operator may prefer one objective over others or care about how multiple objectives are traded off. The GUI represents multiple objectives using the metaphor of an artist's palette. A distinct color is used to represent each objective, and tradeoffs among objectives are balanced in a manner that an artist mixes colors to get the desired shade of color. Thus, human intent is analogous to the artist's shade of color. We call the GUI an "Adverb Palette" where the word "Adverb" represents a specific type of objective for the path, such as the adverbs "quickly" and "safely" in the commands: "travel the path quickly", "make the journey safely". The novel interactive interface provides the user an opportunity to evaluate various alternatives (that tradeoff between different objectives) by allowing her to visualize the instantaneous outcomes that result from her actions on the interface. In addition to assisting analysis of various solutions given by an optimization algorithm, the palette has additional feature of allowing the user to define and visualize her own paths, by means of waypoints (guiding locations) thereby spanning variety for planning. The goal of the Adverb Palette is thus to provide a way for the user and robot to find an acceptable solution even though they use very different representations of the problem. Subjective evaluations suggest that even non-experts in robotics can carry out the planning tasks with a

    A few weeks ago John Lindsay passed away unexpectedly at his home in St. Genis. With his death we have lost a pioneer in detector electronics and one of the founding fathers of the CERN Electronics Group. John came to CERN in 1956 to join the Electronics Group, which was being formed in the SC Division. He thus participated from the beginning in the design, development, production, commissioning and support of electronics for the experiments at the CERN accelerators, initially at the SC and finally at the SPS. From the University of Glasgow he brought his expertise on pulse height analyzers, which were called kick sorters in those days, and did pioneering work with it in the early CERN experiments. He designed read-out systems for successive generations of detectors, such as wire spark chambers, multiwire proportional chambers, calorimeters, etc., often coming up with innovative solutions. Surely one of his finest moments must have been when he worked on complex detector systems, such as liquid argon calo...

    Photonic microcapsules with onion-like topology are microfluidically designed to have cholesteric liquid crystals with opposite handedness in their core and shell. The microcapsules exhibit structural colors caused by dual photonic bandgaps, resulting in a rich variety of color on the optical palette. Moreover, the microcapsules can switch the colors from either core or shell depending on the selection of light-handedness. © 2017 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

  19. Image color reduction method for color-defective observers using a color palette composed of 20 particular colors

    2015-01-01

    This study describes a color enhancement method that uses a color palette especially designed for protan and deutan defects, commonly known as red-green color blindness. The proposed color reduction method is based on a simple color mapping. Complicated computation and image processing are not required by using the proposed method, and the method can replace protan and deutan confusion (p/d-confusion) colors with protan and deutan safe (p/d-safe) colors. Color palettes for protan and deutan defects proposed by previous studies are composed of few p/d-safe colors. Thus, the colors contained in these palettes are insufficient for replacing colors in photographs. Recently, Ito et al. proposed a p/dsafe color palette composed of 20 particular colors. The author demonstrated that their p/d-safe color palette could be applied to image color reduction in photographs as a means to replace p/d-confusion colors. This study describes the results of the proposed color reduction in photographs that include typical p/d-confusion colors, which can be replaced. After the reduction process is completed, color-defective observers can distinguish these confusion colors.

    2017-04-01

    This paper describes the first systematic analysis of the palette of Francesco Hayez, one of the most outstanding artists of European Romanticism, whose painting technique has never been extensively investigated despite the plethora of artistic studies. He lived in a particular moment in the history of painting, as in the first half of the 19th century many synthetic pigments were available, also in tin tubes, but traditional materials were still used. Sixteen paintings on canvas and on panels, created between 1823 and 1868, were analyzed in situ through non-invasive techniques (infrared reflectography and infrared reflection spectroscopy). Imaging investigation provided clues on painting technique, revealing some cases of pentimenti and underdrawings. A preliminary survey was carried out on a hundred pure pigments used up to the 19th century and on new synthetic colours, in order to attain reference spectra for the interpretation of painting spectra. The portable infrared instrument provided insight into Hayez's painting materials, identifying barite, ivory black, lead-tin yellow, Naples yellow, ochres, Prussian blue, and white lead. The pigments were often blended, to obtain a unique fabric appearance or to attain cold shades. The results pointed to a siccative oil as a binder, mixed with white lead so that it could act as a catalyzer in polymerization reactions, and in some cases with a proteinaceous binder and resins. The preparation was made with gypsum and white lead mixed with a siccative oil. The results showed that the artist used a typical traditional palette, throughout his career, in order to lead to brilliant colours and with long-term stability. Anyway, the possible presence of cobalt blue in a few paintings suggests that Hayez had probably started testing the new colours, since the second decade of 19th century.

    Animal integumentary coloration plays a crucial role in visual communication and camouflage, and varies extensively among and within species and populations. To understand the pressures underlying such diversity, it is essential to elucidate the mechanisms by which animals have created novel integumentary coloration. Colours can be produced by selective absorption of light by skin pigments, through light scattering by structured or unstructured tissues, or by a combination of pigments and nanostructures. In this review, we highlight our current understanding of the interactions between pigments and structural integumentary tissues and molecules. We analyse the available evidence suggesting that these combined mechanisms are capable of creating colours and optical properties unachievable by either mechanism alone, thereby effectively expanding the animal colour palette. Moreover, structural and pigmentary colour mechanisms frequently interact in unexpected and overlooked ways, suggesting that classification of colours as being of any particular type may be difficult. Finally, we discuss how these mixtures are useful for investigating the largely unknown genetic, developmental and physical processes generating phenotypic diversity.This article is part of the themed issue 'Animal coloration: production, perception, function and application'. © 2017 The Author(s).

  4. Nature's Palette: Characterization of Shared Pigments in Colorful Avian and Mollusk Shells.

    Pigment-based coloration is a common trait found in a variety of organisms across the tree of life. For example, calcareous avian eggs are natural structures that vary greatly in color, yet just a handful of tetrapyrrole pigment compounds are responsible for generating this myriad of colors. To fully understand the diversity and constraints shaping nature's palette, it is imperative to characterize the similarities and differences in the types of compounds involved in color production across diverse lineages. Pigment composition was investigated in eggshells of eleven paleognath bird taxa, covering several extinct and extant lineages, and shells of four extant species of mollusks. Birds and mollusks are two distantly related, calcareous shell-building groups, thus characterization of pigments in their calcareous structures would provide insights to whether similar compounds are found in different phyla (Chordata and Mollusca). An ethylenediaminetetraacetic acid (EDTA) extraction protocol was used to analyze the presence and concentration of biliverdin and protoporphyrin, two known and ubiquitous tetrapyrrole avian eggshell pigments, in all avian and molluscan samples. Biliverdin was solely detected in birds, including the colorful eggshells of four tinamou species. In contrast, protoporphyrin was detected in both the eggshells of several avian species and in the shells of all mollusks. These findings support previous hypotheses about the ubiquitous deposition of tetrapyrroles in the eggshells of various bird lineages and provide evidence for its presence also across distantly related animal taxa.

    The palette of some of the most representative Brazilian painters from the XIX century was characterized using EDXRF technique. In this work were analyzed paintings of: Eliseu Visconti, Almeida Junior, Rodolfo Amoedo, Henrique Bernardelli, Rafael Frederico, Modesto Brocos, Augusto Rodrigues Duarte and Pedro Peres - all of them belonging to the National Museum of Fine Arts Collection. EDXRF measurements were carried out with a portable system developed by the Nuclear Instrumentation Laboratory, consisting of an X-ray tube Oxford TF3005 with tungsten (W) anode, operating at 25 kV and 100 μA, and a Si-PIN XR-100CR detector from Amptek. In each color and distinct hue of the paint layer were obtained several spectra, with an acquisition time of 300 s and a beam collimation of 2 mm. The spectra were processed and analyzed using the software QXAS-AXIL from IAEA. Some pigments used by the artists were: zinc white, lead white, ochre, umbra, vermilion, Prussian blue, cobalt blue, cadmium yellow, black iron oxide, manganese violet, etc. These results - together with the Computed Radiography analyses - have been used to create a database about the XIX century collection of the National Museum of Fine Arts, in order to assist restorators, conservators, art students and researchers in the field of archaeometry

    John Dyson was born on the 7th January 1941 in Meltham Mills, West Yorkshire, England, and later grew up in Harrogate and Leeds. The proudest moment of John's early life was meeting Freddie Trueman, who became one of the greatest fast bowlers of English cricket. John used a state scholarship to study at Kings College London, after hearing a radio lecture by D. M. McKay. He received a first class BSc Special Honours Degree in Physics in 1962, and began a Ph.D. at the University of Manchester Department of Astronomy after being attracted to astronomy by an article of Zdenek Kopal in the semi-popular journal New Scientist. John soon started work with Franz Kahn, and studied the possibility that the broad emission lines seen from the Orion Nebula were due to flows driven by the photoevaporation of neutral globules embedded in a HII region. John's thesis was entitled ``The Age and Dynamics of the Orion Nebula`` and he passed his oral examination on 28th February 1966.

    Our friend and colleague John Strong was cruelly taken from us by a brain tumour on Monday 31st July, a few days before his 65th birthday John started his career working with a group from Westfield College, under the leadership of Ted Bellamy. He obtained his PhD and spent the early part of his career on experiments at Rutherford Appleton Laboratory (RAL), but after the early 1970s his research was focussed on experiments in CERN. Over the years he made a number of notable contributions to experiments in CERN: The Omega spectrometer adopted a system John had originally developed for experiments at RAL using vidicon cameras to record the sparks in the spark chambers; He contributed to the success of NA1 and NA7, where he became heavily involved in the electronic trigger systems; He was responsible for the second level trigger system for the ALEPH detector and spent five years leading a team that designed and built the system, which ran for twelve years with only minor interventions.

    1993-01-01

    Full text: When John Bertram Adams died on 3 March 1984, CERN lost one of its principal architects. The late Sir John Adams was a very private person who rarely confided in his colleagues. This made the job of his biographer particularly difficult. Michael Crowley- Milling has succeeded admirably, and has performed a very important service. Is it a potted history of CERN, or the story of the building of the PS, or of the SPS? Yes, all of these, but most of all it is a thoughtful and discerning biography and a fitting tribute to a veritable giant of European science and technology. The sub-title,' Engineer Extraordinary' refers not only to John's outstanding ability as a builder of accelerators, but perhaps even more importantly, as a builder of teams and an 'engineer of opinions'. The book describes how John's attention to detail and intuitive engineering skills developed during the early part of his career, when working in radar research, and how he emerged as a natural leader in the building of the CERN PS. Then later, how his statesmanship enabled him to ''...rescue it (the 300 GeV Programme) from seeming political disaster and nurse it through technical problems to a successful conclusion.'' One crucial part of this process described is the visit to CERN in 1970 by Margaret Thatcher, at that time UK Secretary of State for Education and Science, and her subsequent letters of thanks, not only to Bernard Gregory as Director General, but also to John. It is interesting to speculate to what extent the good impression made on that occasion helped many years later, when as Prime Minister Mrs Thatcher decided that Britain should stay in CERN! After the successful commissioning of the SPS, the book goes on to describe the period when the two CERN Laboratories were merged under two Directors General. Unfortunately I found this part a little too low key, given that John and Leon van Hove presided over what was undoubtedly

    2013-01-01

    From molecules to stars, much of the cosmic canvas can be painted in brushstrokes of primary color: the protons, neutrons, and electrons we know so well. But for meticulous detail, we have to dip into exotic hues - leptons, mesons, hadrons, quarks. Bringing particle physics to life as few authors can, Jeremy Bernstein here unveils nature in all its subatomic splendor. In this graceful account, Bernstein guides us through high-energy physics from the early twentieth century to the present, including such highlights as the newly discovered Higgs boson. Beginning with Ernest Rutherford's 1911 explanation of the nucleus, a model of atomic structure emerged that sufficed until the 1930s, when new particles began to be theorized and experimentally confirmed. In the postwar period, the subatomic world exploded in a blaze of unexpected findings leading to the theory of the quark, in all its strange and charmed variations. An eyewitness to developments at Harvard University and the Institute for Advanced Study in Prin...

    John Lumley's contributions to the theory, modeling, and experiments on turbulent flows played a seminal role in the advancement of our understanding of this subject in the second half of the twentieth century. We discuss John's career and his personal style, including his love and deep knowledge of vintage wine and vintage cars. His intellectual contributions range from abstract theory to applied engineering. Here we discuss some of his major advances, focusing on second-order modeling, proper orthogonal decomposition, path-breaking experiments, research on geophysical turbulence, and important contributions to the understanding of drag reduction. John Lumley was also an influential teacher whose books and films have molded generations of students. These and other aspects of his professional career are described.

    John Pendry John Inglesfield and Pedro Echenique write: John Pendry's 65th birthday is on 4 July 2008, and this issue of the Journal of Physics: Condensed Matter is dedicated to him, with articles by friends, colleagues, and former students. By any standards, John Pendry is a great scientist, who has made—and continues to make—an enormous contribution to physics; the wide range of his interests is reflected in the scope of these articles. Not many scientists can establish a completely new and unexpected area of research, but this has been John's achievement in the last few years in the field of metamaterials, materials whose electromagnetic properties depend on their structure rather than the materials of which the structure is built. In this way, structures with effectively negative electrical permittivity and negative magnetic permeability can be constructed, demonstrating negative refraction; through metamaterials scientists now have access to properties not found in nature, and never previously explored experimentally. Never a week goes by without a potential new application of metamaterials, whether it is perfect lensing, or the cloak of invisibility. This has certainly led to tremendous visibility for John himself, with guest lectures all over the world, and radio and television appearances. John Pendry's first paper was published exactly 40 years ago, 'Analytic properties of pseudopotentials' [1], and since then he has published 310 articles at the latest count. But this first paper already reflected something of the way John works. His PhD project, with Volker Heine at the Cavendish Laboratory, was to interpret the scattering of low energy electrons from surfaces, the technique of LEED which was to become the method of choice for determining surface structure. Although the energy of the electrons in LEED is relatively low—say 50 eV—it is much higher than the energy of the conduction electrons, for which pseudopotentials had been devised, and John

    In this first John Adams' Memorial Lecture, an outline is given of his work, especially from the beginning of CERN in 1952 until his death in 1984. The historical survey covers John Adams' technical and managerial contributions to the development of CERN and its accelerators, as well as to fusion research in Britain and Europe. Exemplified by his role as member and president of the International Committee for Future Accelerators (ICFA), Adams' interest in international co-operation is also stressed. In the spirit of this great European, arguments are given for CERN to continue to be the first-rate high-energy physics laboratory which it has been in the past. (orig.)

  7. 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.

He avoided self-aggrandizement and believed that deeds rather than words define one's legacy. Viewed another way, however, Greenleaf's words define his deeds: 48% of his 185 articles are first author works, which is an unusually high proportion for a scientist of his stature. He found that writing a thorough and thoughtful discussion section often led to novel ideas that drove future research. Beyond Greenleaf's words are the many students, postdocs, and collaborators lucky enough to have worked with him and thus learn and carry on his ways of science. His core principles included the following: avoid research "fads," embrace diversity, be the first subject in your own research, adhere to rules of fiscal responsibility, and respect administrative forces-but never back down from them when you know you are right. Greenleaf's integrity ensured he was usually right. He thrived on the axiom of many successful scientists: avoid falling in love with hypotheses, so that when unexpected findings appear, they arouse curiosity instead of fear. Dr. Greenleaf's legacy will include the John and Carol Greenleaf Award for prolific environmental and exercise-related publication in the Journal of Applied Physiology.

    Vibrational spectroscopy is applied on samples obtained from the excavation area of the medieval Monastery (10 th century) of Karaach-Teke in Bulgaria. The results of the corresponding study, reveal the type of materials used for the creation of the wall-paintings and give evidence of Byzantine influence, a fact that further supports the well known impact of Byzantium on the technology and thematic-aesthetic features of iconography in Bulgaria during this era. In addition, the complementarity of FTIR and -Raman spectroscopies in the identification of pigments is indicated

    The introduction of Light Emitting Diodes (LEDs) in the built environment has encouraged myriad applications, often embedded in surfaces as an integrated part of the architecture. Thus the wall as responsive luminous skin is becoming, if not common, at least familiar. Taking into account how walls...... have encouraged architectural thinking of enclosure, materiality, construction and inhabitation in architectural history, the paper’s aim is to define new directions for the integration of LEDs in walls, challenging the thinking of inhabitation and program. This paper introduces the notion...... of “ambiguous walls” as a more “critical” approach to design [1]. The concept of ambiguous walls refers to the diffuse status a lumious and possibly responsive wall will have. Instead of confining it can open up. Instead of having a static appearance, it becomes a context over time. Instead of being hard...

  1. “All That Was Lost Is Revealed”: Motifs and Moral Ambiguity in Over the Garden Wall

    2016-07-01

    Full Text Available Pointedly nostalgic in both its source material and storytelling approach, Over the Garden Wall’s vintage aesthetic is not merely decorative, but ideological. The miniseries responds to recent postmodern fairy tale adaptations by stripping away a century of popular culture references and using motifs, not to invoke and upset increasingly familiar fairy tales, but as an artist’s palette of evocative, available images. In privileging imagery and mood over lessons, Over the Garden Wall captures something that has become vanishingly rare in children’s media: the moral ambiguity of fairy tale worlds.1

  2. John Tyndall's religion: a fragment

    Science.gov (United States)

    Cantor, Geoffrey

    2015-01-01

    Both contemporaries and historians have focused on the high-profile 1874 Belfast Address in which John Tyndall was widely perceived as promulgating atheism. Although some historians have instead interpreted him as a pantheist or an agnostic, it is clear that any such labels do not accurately capture Tyndall's religious position throughout his life. By contrast, this paper seeks to chart Tyndall's religious journey from 1840 (when he was in his late teens) to the autumn of 1848 when he commenced his scientific studies at Marburg. Although he had been imbued with his father's stern conservative Irish Protestantism and opposition to Catholicism, as a youth he seems for a time to have been attracted to Methodism. Later, however, he questioned and rejected his father's religious views and was increasingly drawn to the more spiritual outlook of Ralph Waldo Emerson and Thomas Carlyle, along with a more radical attitude to politics.

    2017-02-01

    Samples from Keith Haring's wall painting of the Necker Children Hospital in Paris were studied by a multi-analytical protocol. X-ray fluorescence (XRF), powder X-ray diffraction (XRDP), Electron microscope (SEM-EDS), Infrared and Raman spectroscopy (μ-FT-IR and μ-Raman) measurements were performed in order to characterize the materials and to identify the art technique used to produce this contemporary work. Materials from the mural suffered from severe detachments of materials and several fragments were found on the ground beneath. Some of these fragments, which were representative of the whole palette and stratigraphic sequence, were collected and studied. The fragments were sufficiently large to enable non-invasive measurements to be performed in order to characterize the materials. A comparison of the data of the techniques applied revealed that Haring's palette was composed of organic pigments such as Naphtol red, phthalocyanine blue and green and Hansa yellow, in accordance with those used previously by the artist in other painted murals.

    In this work, a study on a set of paintings from the most significant altarpiece assigned to Master Jorge Afonso (c. 1470-1540) painting workshop is presented. This altarpiece is composed by fourteen paintings made to the church of Convento de Jesus, in Setúbal, Portugal, and was made circa 1517-19/1530, according to art-history. This set of paintings is compared to one of the other most important Portuguese altarpieces from the 16th century: the panels of the Round Church of the Convento de Cristo, in Tomar, made circa 1510-1515. The aim of this study is to characterize the wooden support, pigments, ground layers materials and technique used in Jorge Afonso workshop by means of complementary analyses. A dendrochronological approach was made in order to corroborate (or not) the historical date initially assigned. Infrared photography (IRP) and reflectography (IRR) allowed the study of the underdrawing technique and macro photography (MP) was used to recognize overlapping layers technique. Cross-sections from the paintings were examined by optical microscopy (OM), and analyzed by μ-X-ray diffraction (μ-XRD), Energy Dispersive X-ray Fluorescence spectroscopy (EDXRF), Scanning Electron Microscopy with Energy Dispersive X-ray Spectroscopy (SEM-EDS), micro-Raman spectroscopy (μ-Raman), micro-Fourier Transform Infrared spectroscopy (μ-FTIR), Pyrolysis Gas Chromatography Mass Spectrometry (py-GC/MS). The characterization of the palette and ground layers and the study of the overlapping of paint layers brought a new insight of the adopted painting techniques by the most important group of painters working in Portugal in the 16th century - the Lisbon workshop, leaded by Master Jorge Afonso.

This article, by contrast, argues that a broader understanding of Mill's ethical liberalism, his utilitarianism, and his feminism casts doubt over such an assumption. New insights into Mill's approach to sex, sexual activity, and the regulation of prostitution reveal an altogether more nuanced and activist approach. We conclude that John Stuart Mill would a...

    Medieval wall painting fragments, taken at the medieval Mosque of al-Qarawiyyin in Fez, have been investigated by means of X-ray fluorescence and UV-Vis-NIR diffuse reflectance spectroscopies. The analyses permitted to determine the palette of pigments used by craftsmen of the time. Hematite or red ochre were used to obtain red brown colours, calcite for white, copper-based pigments for blue and blue-grey shades while a mixture of cinnabar, lead-based pigments and hematite was adopted to make red-orange colours. Furthermore, the analysis of mortars (external layer and plaster) on these wall painting samples revealed that they are composed mainly by calcite and sometimes by additional compounds such as quartz and gypsum.

Firor, a former Director of the High Altitude Observatory and the National Center for Atmospheric Research, and a founder of the Solar Physics Division of the American Astronomical Society, died of Alzheimer's disease in Pullman, Washington on November 5, 2007, he was 80. He was born in Athens Georgia on October 18, 1927, where his father was a professor of agricultural economics. John had an unusually diverse scientific career. His interest in physics and astrophysics began while serving in the army, during which time he was assigned to the Los Alamos National Laboratory, where he guarded highly radioactive materials (many have heard him describe how informal the protections were compared to later times). After his service he returned to college and graduated in physics from Georgia Tech in 1949. He received his Ph.D. from the University of Chicago in 1954, writing his thesis on cosmic rays under John Simpson. John Firor would later remark that: "If you needed cosmic rays to actually do anything, you are sunk." That thought, partly in jest, may help explain his motivation for moving to so many new scientific and management pursuits. John moved from cosmic ray physics to radio astronomy (particularly of the Sun) when he began work at the Carnegie Institution of Washington's Department of Terrestrial Magnetism, where he remained until 1961. During this time, he met Walter Orr Roberts, then the Director of the High Altitude Observatory (HAO) in Boulder, Colorado. HAO was then affiliated with the University of Colorado. In 1959, a movement began to upgrade the atmospheric sciences in the United States by establishing a National Center, where the largest, most important atmospheric research problems could be addressed. Roberts became the first Director of NCAR, as well as the first president of the University Corporation for Atmospheric Research (UCAR), the consortium of universities that was commissioned to manage and staff the new Center.

  3. First wall

    International Nuclear Information System (INIS)

    Omori, Junji.

    1991-01-01

    Graphite and C/C composite are used recently for the first wall of a thermonuclear device since materials with small atom number have great impurity allowable capacity for plasmas. Among them, those materials having high thermal conduction are generally anisotropic and have an upper limit for the thickness upon production. Then, anisotropic materials are used for a heat receiving plate, such that the surfaces of the heat receiving plate on the side of lower heat conductivity are brought into contact with each other, and the side of higher thermal conductivity is arranged in parallel with small radius direction and the toroidal direction of the thermonuclear device. As a result, the incident heat on an edge portion can be transferred rapidly to the heat receiving plate, which can suppress the temperature elevation at the surface to thereby reduce the amount of abrasion. Since the heat expansion coefficient of the anisotropic materials is great in the direction of the lower heat conductivity and small in the direction of the higher heat conductivity, the gradient of a thermal load distribution in the direction of the higher heat expansion coefficient is small, and occurrence of thermal stresses due to temperature difference is reduced, to improve the reliability.

    It was 20 years ago this week that the Berlin wall was opened for the first time since its construction began in 1961. Although the signs of a thaw had been in the air for some time, few predicted the speed of the change that would ensue. As members of the scientific community, we can take a moment to reflect on the role our field played in bringing East and West together. CERN’s collaboration with the East, primarily through links with the Joint Institute for Nuclear Research, JINR, in Dubna, Russia, is well documented. Less well known, however, is the role CERN played in bringing the scientists of East and West Germany together. As the Iron curtain was going up, particle physicists on both sides were already creating the conditions that would allow it to be torn down.

    John Perdrix, astronomical historian and co-founder of the Journal of Astronomical History and Heritage, died on 27 June 2005. John Louis Perdrix was born in Adelaide, Australia, on 30 June 1926. After studying chemistry at Melbourne Technical College and working in industry, he joined the Commonwealth Scientific and Industrial Research Organisation's Division of Minerals and Geochemistry. In 1974 the Division relocated to the Western Australian capital, Perth, and John spent the rest of his working life there involved in geochemical research. From his teenage years John had a passion for astronomy, which he fine-tuned through the Astronomical Society of Victoria and the Victorian Branch of the British Astronomical Association. He was very active in both groups, serving as President of the former and Secretary/Treasurer of the latter. He was also an FRAS, and a member of the AAS, the BAA parent body, and the IAU (Commission 41)?no mean feat for an Australian amateur astronomer. Throughout his life, he was a strong advocate of close amateur-professional relations. John's main research interest was history of astronomy, and over the years he wrote a succession of research papers, mainly about aspects of Australian astronomy. His well-researched and neatly-illustrated papers on the Melbourne Observatory and the Great Melbourne Telescope are classics, and when the Observatory's future was in the balance they played a key role in the State Government's decision to convert this unique facility into a museum precinct. To support his research activities, John built up an amazing library that developed its own distinctive personality and quickly took over his house and garage before invading commercial storage facilities! Apart from writing papers, John had an even greater passion for editing and publishing. From 1985 to 1997 he produced the Australian Journal of Astronomy, and in 1998 this was replaced by the Journal of Astronomical History and Heritage (JAH2). Both

    Science.gov (United States)

    Scarfe, Colin

    2009-01-01

    John Leroy Climenhaga was born on 7 November 1916 on a farm some 10 km from Delisle, a small town on the Canadian prairies, located about 50 km south-west of Saskatoon, Saskatchewan, and died at his home in Victoria, British Columbia, on 27 May 2008. His parents, Reuben and Elizabeth (nee Bert) Climenhaga, were farming folk, and he carried their honest and open attitude to the world throughout his life. John was the seventh born, and last to die, of their ten children. His father also served as an ordained minister of the Brethren in Christ. In early adulthood, John worked on his father's farm, but then attended the University of Saskatchewan, obtaining a B.A. with Honors in Mathematics and Physics and an M.A. in Physics, in 1945 and 1949 respectively. Between these events he worked as a Physics Instructor at Regina College from 1946 to 1948. In 1949 Climenhaga joined the faculty of Victoria College, as one of only two physicists in a small institution that was then part of the University of British Columbia. He remained in Victoria for the rest of his career, playing a major role in the College's growth into a full-fledged university, complete with thriving graduate programs in physics and astronomy as well as in many other fields. He served as Head of the Physics Department during the 1960s, a period which saw the College become the University of Victoria, with a full undergraduate program in Physics, and campaigned successfully for the establishment of a program in Astronomy, which began in 1965. From 1969 until 1972 he held the position of Dean of Arts and Science, and championed the university's participation in the Tri-University Meson Facility, whose high-current medium-energy beam was ideal for the production and study of mesons and their physics. That period was a turbulent one in the university's history, but John's integrity and his balanced and fair-minded approach to conflicts were of immeasurable importance in steering the young institution through it

    John J. Hillman, a dedicated NASA civil servant, spectroscopist, astrophysicist, planetary scientist, and mentor, died on February 12, 2006 of ocular melanoma at his home in Columbia, Maryland. His professional and personal interests were wide-reaching and varied, and he devoted his career to the advancement of our understanding of the beauty and wonder in the world around us. His love of nature, art, and science made him a true Renaissance man. John was born in Fort Jay, New York, on November 22, 1938, and was raised in Washington, D.C. He received his B.S., M.S., and Ph.D. degrees in Physics from American University in 1967, 1970, and 1975, respectively. He began working at NASA's Goddard Space Flight Center, then in its infancy, in 1969, juggling a full-time position as a Research Physicist, the completion of his M.S. and Ph.D. degrees, and a young family. His background in molecular spectroscopy enabled him to apply his skills to numerous disciplines within NASA: infrared and radio astronomy; electronic, vibrational, and rotational structure of interstellar molecules; solar and stellar atmospheres; and planetary atmospheres. He published more than 70 journal papers in these disciplines. He was a frequent contributor to the Ohio State University International Symposium on Molecular Spectroscopy, and possessed a rare ability to bridge the gap between laboratory and remote sensing spectroscopy, bringing scientists from different disciplines together to understand our Universe. The last fifteen years of John's career were devoted to the development of acousto-optic tunable filter (AOTF) cameras. He championed this technology as a low-cost, low-power alternative to traditional imaging cameras for in situ or remotely sensed planetary exploration. It was within this context that I got to know John, and eventually worked closely with him on the demonstration and application of this technology for planetary science using ground-based telescopes in New Mexico, California

  5. A New Reading of Shakespeare's King John.

    Science.gov (United States)

    Usher, Peter D.

    1995-12-01

    Shakespeare wrote King John c.1594, six years after the defeat of the Spanish Armada, and ~ 50 years after publication of the Copernican heliocentric hypothesis. It is said to be the most unhistorical of the History Plays, ``anomalous'', ``puzzling'', and ``odd'', and as such it has engendered far more than the customary range of interpretive opinion. I suggest that the play alerts Elizabethans not just to military and political threats, but to a changing cosmic world view, all especially threatening as they arise in Catholic countries. (a) Personification characterizes the play. John personifies the old order, while Arthur and the Dauphin's armies personify the new. I suggest that Shakespeare decenters King John just as Copernicus decentered the world. (b) Hubert menaces Arthur's eyes for a whole scene (4.1), but the need for such cruelty is not explained and is especially odd as Arthur is already under sentence of death (3.3.65-66). This hitherto unexplained anomaly suggests that the old order fears what the new might see. (c) Eleanor's confession is made only to Heaven and to her son the King (1.1.42-43), yet by echoing and word play the Messenger from France later reveals to John that he is privy to it (4.2.119-124). This circumstance has not been questioned heretofore. I suggest that the Messenger is like the wily Hermes (Mercury), chief communicator of the gods and patron of the sciences; by revealing that he moves in the highest circles, he tells John that he speaks with an authority that transcends even that of a king. The message from on high presages more than political change; it warns of a new cosmic and religious world order (d) Most agree that John is a weak king, so Shakespeare must have suspected flaws in the old ways. He would have known that Tycho Brahe's new star of 1572, the comet of 1577, and the 1576 model of his compatriot Thomas Digges, were shattering old ideas. (e) The tensions of the play are not resolved because in 1594 the new order was

  6. John Holt Stanway: Gone to Texas

    Bryan, J.

    2008-01-01

    John Holt Stanway (1799Ð1872) was an amateur astronomer who lived in Manchester, England until 1845. He was in contact with the English Ôgrand amateurÕ astronomer, William Henry Smyth, who supported him for Fellowship of the Royal Astronomical Society and evidently advised him on how to build and equip an observatory. Apparently, Stanway had an observatory at Chorlton-cum-Hardy in 1837. In 1845, Stanway left for the United States in response to serious business problems. En route, he met Ashbel Smith, a representative of the government of the Republic of Texas, who convinced Stanway to go to Texas. There he changed his name to John H. Smythe Stanley and settled in Houston, where he re-established his observatory. He became a commercial photographer and wrote about astronomy and other scientific subjects in Houston newspapers until his death in 1872.

  11. Characterization of the Sclerotinia sclerotiorum cell wall proteome.

    Science.gov (United States)

    Liu, Longzhou; Free, Stephen J

    2016-08-01

    We used a proteomic analysis to identify cell wall proteins released from Sclerotinia sclerotiorum hyphal and sclerotial cell walls via a trifluoromethanesulfonic acid (TFMS) digestion. Cell walls from hyphae grown in Vogel's glucose medium (a synthetic medium lacking plant materials), from hyphae grown in potato dextrose broth and from sclerotia produced on potato dextrose agar were used in the analysis. Under the conditions used, TFMS digests the glycosidic linkages in the cell walls to release intact cell wall proteins. The analysis identified 24 glycosylphosphatidylinositol (GPI)-anchored cell wall proteins and 30 non-GPI-anchored cell wall proteins. We found that the cell walls contained an array of cell wall biosynthetic enzymes similar to those found in the cell walls of other fungi. When comparing the proteins in hyphal cell walls grown in potato dextrose broth with those in hyphal cell walls grown in the absence of plant material, it was found that a core group of cell wall biosynthetic proteins and some proteins associated with pathogenicity (secreted cellulases, pectin lyases, glucosidases and proteases) were expressed in both types of hyphae. The hyphae grown in potato dextrose broth contained a number of additional proteins (laccases, oxalate decarboxylase, peroxidase, polysaccharide deacetylase and several proteins unique to Sclerotinia and Botrytis) that might facilitate growth on a plant host. A comparison of the proteins in the sclerotial cell wall with the proteins in the hyphal cell wall demonstrated that sclerotia formation is not marked by a major shift in the composition of cell wall protein. We found that the S. sclerotiorum cell walls contained 11 cell wall proteins that were encoded only in Sclerotinia and Botrytis genomes. © 2015 The Authors.

    Kraus, John D., Jr.; Marhefka, Ronald J.

    2005-12-01

    John Daniel Kraus, 94, of Delaware, Ohio, director of the Ohio State University "Big Ear" Radio Observatory, physicist, inventor, and environmentalist died 18 July 2004 at his home in Delaware, Ohio. He was born on 28 June 1910 in Ann Arbor, Michigan. He received a Bachelor of Science in 1930, a Master of Science in 1931, and a PhD in physics in 1933 (at 23 years of age), all from the University of Michigan, Ann Arbor. During the 1930s at Michigan, he was involved in physics projects, antenna consulting, and in atomic-particle-accelerator research using the University of Michigan's premier cyclotron. Throughout the late 1920s and the 1930s, John was an avid radio amateur with call sign W8JK. He was back on the air in the 1970s. In 2001 the amateur radio magazine CQ named him to the inaugural class of its Amateur Radio Hall of Fame. He developed many widely used innovative antennas. The "8JK closely spaced array" and the "corner reflector" were among his early designs. Edwin H. Armstrong wrote John in July 1941 indicating in part, "I have read with interest your article in the Proceedings of the Institute on the corner reflector...Please let me congratulate you on a very fine piece of work." Perhaps John's most famous invention, and a product of his intuitive reasoning process, is the helical antenna, widely used in space communications, on global positioning satellites, and for other applications. During World War II, John was in Washington, DC as a civilian scientist with the U.S. Navy responsible for "degaussing" the electromagnetic fields of steel ships to make them safe from magnetic mines. He also worked on radar countermeasures at Harvard University's Radio Research Laboratory. He received the U.S. Navy Meritorious Civilian Service Award for his war work. In 1946 he took a faculty position at Ohio State University, becoming professor in 1949, and retiring in 1980 as McDougal Professor Emeritus of Electrical Engineering and Astronomy. Even so, he never retired

    Full Text Available John Paul College, a K-12 School in Queensland, Australia, recognises the centrality of classroom teachers to the ongoing improvement of student outcomes. The college has implemented a multi-tiered professional renewal and assessment process. These changes of emphasis are the result of significant research and subsequent/associated professional discussion and were supported during the EBA decision-making in 2012. The professional renewal process at John Paul College guides teachers through a cycle of goal setting (related to any aspect of teacher practice which aims to improve student learning and achievement; ongoing discussion between the teacher and a mentor which determines actions; directed classroom observations (3 per term and associated pre and post reflection/discussion; leading to application of changed practice toward achieving the criteria of the goals. The principles of the professional renewal program are to:  enhance development along accepted school-wide, team and department goals;  encourage professional pedagogical reflections and conversations with a colleague/mentor;  motivate improved performance and highlight the next steps in a teacher’s development. Through the introduction of professional renewal, attestation and exemplary teacher processes, the leadership and teachers of John Paul College have achieved an appropriate and innovative balance between self-directed, peer supported/directed and college-wide, strategic initiatives. Each member of the teaching team, from graduate to senior leaders are actively engaged in personalised programs of professional growth which is specifically aimed at improved learning and outcomes of the college’s students.

    Here we provide reflections of and a tribute to John M. Olson, a pioneering researcher in photosynthesis. We trace his career, which began at Wesleyan University and the University of Pennsylvania, and continued at Utrech in The Netherlands, Brookhaven National Laboratory, and Odense University in Denmark. He was the world expert on pigment organization in the green photosynthetic bacteria, and discovered and characterized the first chlorophyll-containing protein, which has come to be known as the Fenna-Matthews-Olson (FMO) protein. He also thought and wrote extensively on the origin and early evolution of photosynthesis. We include personal comments from Brian Matthews, Raymond Cox, Paolo Gerola, Beverly Pierson and Jon Olson.

We succeeded in getting a copy of John's lecture. In the lecture, many of the arguments that John had lucidly stressed in his writings appear once more, but there are also extremely interesting new remarks which, to our knowledge, have not been presented elsewhere. In particular he decided, as pointed out by the very choice of the title of his lecture, to call attention to the fact that the theory presents two types of difficulties, which Dirac classified as first and second class. The former are those connected with the so-called macro-objectification problem, the latter with the divergences characterizing relativistic quantum field theories. Bell describes the precise position of Dirac on these problems and he stresses appropriately how, contrary to Dirac's hopes, the steps which have led to a partial overcoming of the second class difficulties have not helped in any way whatsoever to overcome those of the first class. He then proceeds to analyse the origin and development of the Dynamical Reduction Program and draws attention to the problems that still affect it, in particular that of a consistent relativistic generalization. When the two meetings Are there quantum jumps? and On the present status of Quantum Mechanics were organized in Trieste and Losinj (Croatia), on 5-10 September 2005, it occurred to us that this lecture, which has never been published, might represent an

    John the Ripper (JtR) is an open source software package commonly used by system administrators to enforce password policy. JtR is designed to attack (i.e., crack) passwords encrypted in a wide variety of commonly used formats. While parallel implementations of JtR exist, there are several limitations to them. This research reports on two distinct algorithms that enhance this password cracking tool using the Message Passing Interface. The first algorithm is a novel approach that uses numerous processors to crack one password by using an innovative approach to workload distribution. In this algorithm the candidate password is distributed to all participating processors and the word list is divided based on probability so that each processor has the same likelihood of cracking the password while eliminating overlapping operations. The second algorithm developed in this research involves dividing the passwords within a password file equally amongst available processors while ensuring load-balanced and fault-tolerant behavior. This paper describes John the Ripper, the design of these two algorithms and preliminary results. Given the same amount of time, the original JtR can crack 29 passwords, whereas our algorithms 1 and 2 can crack an additional 35 and 45 passwords respectively.

  4. John Dewey’s Feminist Legacy

    Directory of Open Access Journals (Sweden)

    Marta Vaamonde Gamo

    2016-07-01

    Full Text Available This article demonstrates how feminism welcomed and was influenced by the pragmatism of John Dewey. While in real terms his impact on European feminism has been minimal, this was not the case in contemporary America. In this article we study both how Dewey’s ideas were received amongst American feminists, as well as certain aspects of his thinking that could be enormously useful in present-day debates between critical and postmodern feminists. We compare the Deweyan and feminist arguments against the traditional dualisms that acted as philosophical support for social inequality, paying particular attention to mind–body dualism, and the consequent undervaluation of physical and emotional wellbeing. We also show that John Dewey’s proposals were, in fact, more radical than those of the feminists of the day. Indeed, democracy has to be understood as a way of life that affects every dimension of experience, and is crucial to the personal and social growth that enables the unjust social inequalities between men and women to be overcome.

    John Napier (1550–1617) is celebrated today as the man who invented logarithms—an enormous intellectual achievement that would soon lead to the development of their mechanical equivalent in the slide rule: the two would serve humanity as the principal means of calculation until the mid-1970s. Yet, despite Napier’s pioneering efforts, his life and work have not attracted detailed modern scrutiny. John Napier is the first contemporary biography to take an in-depth look at the multiple facets of Napier’s story: his privileged position as the eighth Laird of Merchiston and the son of influential Scottish landowners; his reputation as a magician who dabbled in alchemy; his interest in agriculture; his involvement with a notorious outlaw; his staunch anti-Catholic beliefs; his interactions with such peers as Henry Briggs, Johannes Kepler, and Tycho Brahe; and, most notably, his estimable mathematical legacy.

  6. Translating The Infinities by John Banville

    Irene Abigail Piccinini

    2015-12-01

    Full Text Available Abstract - John Banville’s talent as a prose stylist is widely recognized. The polished elegance of his phrases constitutes a continuing and fascinating challenge for his translator, due to the intricacies of the source text, its manifold registers and lexical choices. In his novel The Infinities, in Italian Teoria degli Infiniti, John Banville takes cue from Kleist’s Amphytrion to devise a novel where classicality interweaves with science and science fiction through the invention of a world where the ancient gods intermingle with the humans while waiting for the death of Adam Godley, a famous mathematician who explained how an infinity of worlds exist and interact with each other. To translate this book I had not only to work extensively on lexis and style, but also to do considerable research to render the many literary and non literary references. Some examples of these struggles with the source text during the translation process are given in the present paper. Riassunto - John Banville, autore irlandese noto per la sua prosa raffinata, scrive in una lingua che rappresenta una sfida continua e affascinante per chi lo traduce. La sua complessità stilistica, che sfrutta molteplici registri linguistici e si avvale di scelte lessicali cui spesso è arduo trovare un traducente italiano soddisfacente, costringe il traduttore a fare ricorso a tutte le sottigliezze del proprio mestiere per restituire quanto più possibile l’eleganza dell’originale nella propria lingua. Nel romanzo The Infinities, tradotto in italiano come Teoria degli infiniti (Guanda, Parma 2011, Banville prende spunto dall’Anfitrione di Kleist per costruire un romanzo che guarda alla classicità sconfinando in un misto di scienza e fantascienza con la concezione di un’infinità di mondi paralleli teorizzata dal matematico Adam Godley, il protagonista morente al cui capezzale si radunano uomini e antichi dei in attesa che il cerchio della vita e della morte si compia

    We recall the contributions that John Lumley made to turbulence modeling in the 1970s and 1980s. In these early days, computer power was feeble by today's standards, and eddy-viscosity models were prevalent in CFD. Lumley recognized, however, that second-moment closures represent the simplest level at which the physics of turbulent flows can reasonably be represented. This is especially true when the velocity field is coupled to scalar fields through buoyancy, as in the atmosphere and oceans. While Lumley was not the first to propose second-moment closures, he can be credited with establishing the rational approach to constructing such closures. This includes the application of various invariance principles and tensor representation theorems, imposing the constraints imposed by realizability, and of course appealing to experimental data in simple, canonical flows. These techniques are now well-accepted and have found application far beyond second-moment closures.

  9. John Stuart Mill's Philosophy of Persuasion

    2014-02-01

    Full Text Available In his youth, John Stuart Mill followed his father’s philosophy of persuasion but, in 1830, Mill adopted a new philosophy of persuasion, trying to lead people incrementally towards the truth from their original stand-points rather than engage them antagonistically. Understanding this change helps us understand apparent contradictions in Mill’s cannon, as he disguises some of his more radical ideas in order to bring his audience to re-assess and authentically change their opinions. It also suggests a way of re-assessing the relationship between Mill’s public and private works, to which we should look if we are attempting to understand his thought.

    Full Text Available El término “democracia” se encuentra completamente ausente del famoso libro de John Rawls, Teoría de la justicia. En Liberalismo político, en cambio, Rawls discute varios de los muchos temas sobre los que el concepto de democracia nos invita a reflexionar. En este escrito concentro mi atención en una de esas discusiones: la tensión entre constitucionalismo y democracia. Más específicamente, procuro examinar de qué modo Rawls trata de afirmar el doble compromiso que toda constitución quiere honrar, esto es, el compromiso con el ideal de la autonomía individual, y el compromiso con el ideal del auto-gobierno colectivo.

    In May 1997, the Chief Executive of BP, John Browne, delivered a speech on global climate change at Stanford University, California. A shortened version of the speech is presented. BP have accepted the possibility of a link between greenhouse gas emissions and climate change and are basing their policies on that acceptance. The company is committed to a step-by-step process, involving both action to develop solutions and continuing research to improve knowledge, that will balance the requirements of economic development and environmental protection. Five specific steps are outlined. These are: the monitoring and controlling of carbon dioxide emissions in all aspects of the company's operations increasing the level of support given to continuing scientific work on climate change; technology transfer and joint implementation with other parties to limit and reduce net emission levels; the development of alternative energy sources, in particular, solar power; contributing to the public policy debate in search of wider global answers to the problem.

    2013-01-01

    By any standards, John Adams had a most remarkable career. He was involved in three important, emerging technologies, radar, particle accelerators and controlled fusion, and had an outstanding impact on the last two. Without a university education, he attained hierarchical positions of the highest level in prestigious national and international organizations. This article covers the CERN part of his career, by offering some personal insights into the different facets of his contributions to major accelerator projects, from the first strong-focusing synchrotron, the PS, to the SPS and its conversion to a proton–antiproton collider. In particular, it outlines his abilities as a leader of an international collaboration, which has served as an example for international initiatives in other disciplines.

    Observational and experimental data pertaining to gravity and cosmology are changing our view of the Universe. General relativity is a fundamental key for the understanding of these observations and its theory is undergoing a continuing enhancement of its intersection with observational and experimental data. These data include direct observations and experiments carried out in our solar system, among which there are direct gravitational wave astronomy, frame dragging and tests of gravitational theories from solar system and spacecraft observations. This book explores John Archibald Wheeler's seminal and enduring contributions in relativistic astrophysics and includes: the General Theory of Relativity and Wheeler's influence; recent developments in the confrontation of relativity with experiments; the theory describing gravitational radiation, and its detection in Earth-based and space-based interferometer detectors as well as in Earth-based bar detectors; the mathematical description of the initial value pro...

  16. John Dewey and early Chicago functionalism.

    Backe, A

    2001-11-01

    John Dewey and James Angell are regarded respectively as the founder and systematizer of the Chicago school of functional psychology. The early Chicago school traditionally has been portrayed as a unified theoretical approach based primarily on William James's naturalist theory of mental processes. It is argued in this article that although the psychology systematized by Angell bore a close affinity to James's naturalism, Dewey's own psychology was based primarily on the neo-Hegelian philosophy of Thomas Hill Green. Through a review of a number of Dewey's major writings, Green's neo-Hegelian philosophy is shown to have influenced Dewey's views on psychological concepts such as reaction, emotion, and perception during the formative period of the Chicago school. The interpretation of Dewey's psychology developed in this article leads to the conclusion that early Chicago functionalism should not be regarded as a unified theoretical approach.

  17. John Locke and the right to resistance

    Full Text Available John Locke was a great thinker and many works have been devoted to clear up his theories. One of the most significant, stated in his principal work, Two Treatises of Government, is the theory of the right to resistance. It was a bit revolutionary then, and to a large extent it is today. Domination of legal positivism is negation of that, by Locke, natural right. However, the fact is that in recent times the resistance to the established power occurs in a number of countries and in different forms, so that the idea of the right to resistance becomes live question again. In this regard it is interesting to consider Locke's viewpoint on this important issue and to determine whether his theory on the resistance is applicable in modern societies.

  18. John Ruskin and the Savage Gothic

    2015-06-01

    Full Text Available John Ruskin’s provocative theories concerning Gothic art and architecture bear serious consideration in light of the formative debates concerning “primitive” art and its relation to modern European society. Like many primitivists, Ruskin’s advocacy for the medieval was motivated by a reformist zeal concerning the state of modern industrial Europe. He differs markedly in his ideas concerning the value and uses of the "savage” Gothic for modern audiences. Ruskin rejected the random borrowing of stylistic elements, stressing instead the artisanal process and the communal role of Gothic monuments. It is also significant that Ruskin problematises the relationship between “primitive” and modern by repeatedly acknowledging his position as a modern viewer and emphasising the process through which he makes (artisan-like his interpretive history of the Gothic. Rejecting the mastering gaze, Ruskin constantly reminds readers that their view of this pre-modern work is fragmentary and disjunctive.

    Full Text Available Resumen Los discursos cruzados son el soporte común del presente número de Cuadernos. El cruce que planteamos tiene como protagonistas al artista Robert Smithson y a los arquitectos Adam Caruso y Peter St John. Estos últimos hacen mención del trabajo del artista norteamericano para explicar su proyecto de remodelación de Stortorget, la plaza de la catedral en el centro de Kalmar, Suecia. A partir de aquí, comenzamos una exploración del trabajo y las preocupaciones de ambos que nos permite dibujar convergencias y sintonías procesuales por encima de las diferencias temáticas, ideológicas y estilísticas. Al disponer en paralelo la obra de Smithson y Caruso St John descubrimos vibraciones y resonancias que muestran una interacción productiva de sus preocupaciones. La materia se convierte en sus propuestas en un objeto activo y sensible, un depósito energético con el que operar. El traslado de piedras en Stortorget convoca la memoria de la ciudad del mismo modo que el basalto y la sal del Spiral Jetty, erosionados por el tiempo, nos hablan de procesos abiertos. El tiempo y la memoria pasan a ser soportes estratégicos con los que construyen sus miradas. Los objetos se disuelven en las relaciones que establecen con su entorno produciendo equilibrios frágiles e instantáneos. De esta manera el artículo pretende generar un vórtice de reflexión, una espiral en cuyo recorrido se manifiesten las tensiones parciales del cruce propuesto, sus fijezas momentáneas.

    2007-12-01

    John Norris Bahcall, one of the most creative and influential astrophysicists of his generation — a scientist who helped prove what makes the Sun shine and helped make the Hubble Space Telescope a reality — passed away in Pasadena, California, on 17 August 2005. Bahcall died peacefully in his sleep from a rare blood disorder. For the past 35 years, Bahcall was the Richard Black Professor of Natural Sciences at the Institute for Advanced Study in Princeton, New Jersey, where he created one of the leading astrophysics programs in the world. Active and working to the end, Bahcall said that he was always grateful for a full and happy life that exceeded his wildest expectations. Bahcall died as he lived, surrounded by the family he loved, embracing life to its fullest, happy, working and joking to the end. Bahcall's stellar career encompassed seminal contributions in numerous fields of astrophysics as well as extraordinary leadership on behalf of the scientific community, including the American Astronomical Society, the American Physical Society, the National Academy of Sciences, NASA, and Congress. Bahcall's contributions made him one of the scientific leaders of his time. He had been recognized by numerous awards including the 1998 National Medal of Science from President Clinton, the Gold Medal of the Royal Astronomical Society, the Medal of the Swedish Royal Academy, the Dan David Award, the Fermi Award, the first Hans Bethe Prize, the Franklin Medal, the Comstock Prize in physics, NASA's Exceptional Scientific Achievement Medal, NASA's Distinguished Public Service Medal, and the top awards of the American Astronomical Society — including the Russell Award, the Heineman Prize, and the Warner Prize. Bahcall was elected to the National Academy of Sciences in 1976 and to the American Philosophical Society in 2001. He was the recipient of Honorary Degrees from numerous universities around the world. Bahcall's scientific interests and expertise ranged from neutrino

    2011-07-01

    Full Text Available The interview focuses on some aspects of the composer’s work with electronics. Palmer, described by the critics as «undoubtedly the most visionary composer of his generation» speaks about the composers and musical works that have had a major impact on him. He also mentions the friendship with John Cage, his numerous travels – with particular emphasis on Japan – and the influence of Eastern culture on his musical mind. The composer discusses the notion of causality explored in Renge-Kyo, the meditative nature of Transient and Inwards, and spirituality as the central theme of both acousmatic works In the Temple and I Am. The electronic medium is also por- trayed as a mirror of an intense and vivid preoccupation for intimacy and perpetual search for timbral qualities that by now characterize most of his music. Another important aspect of Palmer’s work mentioned in the interview is the collaboration with some established performers and its importance for the realization of a musical work.

  2. John Bardeen and the theory of superconductivity

    1992-01-01

    Bardeen's knowledge of the experimental data had bounded the theory of superconductivity quite tightly before B, C and S developed their theory. When one speaks with John Bardeen's friends about him, one frequently hears words such as brilliant, quiet, persistent, generous, visionary, athletic, kind, thoughtful and remarkable. It is the author's good fortune to have the chance to recount some incidents from his life that are connected with the theory of superconductivity. This article draws on the author's personal memories; his many other friends and colleagues will set down their own recollections elsewhere. The evolution of the microscopic theory of superconductivity closely parallels the scientific life of Joh Bardeen. Starting with his PhD dissertation, done under the guidance of Eugene Wigner, he spent much of his life developing an understanding of electron interaction effects and transport properties of metals, semiconductors and superconductors. His fascination with the remarkable phenomenon of superconductivity goes back to his graduate student days at Princeton. Although interrupted during the war years and in the late 1940's at Bell Labs, he returned to this perplexing topic when he moved to the University of Illinois in 1951. 20 refs., 7 figs

    For the first time, all five of John Napier’s works have been brought together in English in a single volume, making them more accessible than ever before. His four mathematical works were originally published in Latin: two in his lifetime (1550–1617), one shortly after he died, and one over 200 years later. The authors have prepared three introductory chapters, one covering Napier himself, one his mathematical works, and one his religious work. The former has been prepared by one of Napier’s descendants and contains many new findings about Napier’s life to provide the most complete biography of this enigmatic character, whose reputation has previously been overshadowed by rumour and speculation. The latter has been written by an academic who was awarded a PhD for his thesis on Napier at the University of Edinburgh, and it provides the most lucid and coherent coverage available of this abstruse and little understood work. The chapter on Napier’s mathematical texts has been authored by an experienced...

  4. John Dique: dialysis pioneer and political advocate.

    George, Charles R P

    2016-02-01

    John Dique (1915-1995) epitomized the internationalism of medicine, the intellectual and manual dexterity of many pioneers of dialysis, and the social concern evinced by many nephrologists. Born in Burma of French, German, British and Indian ancestry; educated in India; an Anglo-Indian who described himself as British without ever having visited Britain; he moved to Australia in 1948 to escape the murderous inter-ethnic conflict that befell multicultural India as it and Pakistan became independent. Settling in Brisbane, he pioneered several novel medical techniques. After inventing some simple equipment to facilitate intravenous therapy, he established a neonatal exchange blood transfusion programme. Then, between 1954 and 1963, he personally constructed and operated two haemodialysis machines with which to treat patients suffering from acute renal failure, the first such treatment performed in Australasia. His patients survival results were, for the era, remarkable. He subsequently helped found the Royal Australasian College of Pathologists and went on to establish a successful private pathology practice. The latter years of his life, however, saw him become a social and political advocate. He fiercely opposed the emerging ideologies of multiculturalism and social liberalism that, he predicted, would seriously damage the national fabric of Western society. Public vilification ensued, his medical achievements disregarded. It does seem likely, however, that in none of the areas that he touched - whether medical, social, or political - has the last word yet been said.

  5. John Stuart Mill on socialism and accountability

Ele rejeitou enfaticamente os modelos centralistas de socialismo por entender que eles levam a uma grande concentração de poder que compromete a liberdade. Para J. S. Mill, o socialismo deve ser implantado lentamente a partir de reformas amplamente discutidas que favoreçam a cidadania econômica dos trabalhadores, promovam a participação deles nas decisões referentes ao processo produtivo e em associações voluntárias. J. S. Mill acreditava que a competição econômica é essencial para o adequado funcionamento de uma economia socialista. Ele não esperava que tal economia se tornasse uma realidade em um futuro próximo.

    In an Open Letter to Pope John Paul II, written on World Population Day (July 11) 1991, Dr. Fred Sai, President of International Planned Parenthood Federation (IPPF), called for a dialogue on voluntary family planning as a means of avoiding unwanted pregnancy. A half million women die each year from pregnancy-related causes--a death toll that could be dramatically reduced by universal access to low cost, effective contraception. Family planning further represents the best protection against abortion. The Catholic Church's vehement opposition to abortion and family planning methods other than periodic abstinence is in marked contrast to its support to human rights in other settings. The Church has supported struggles for economic ju stice in and among nations, sided with the poor, and advocated for transitions to democracy. At the same time, the family planning movement--which has as its overall objective the protection of the health and welfare of women, children, and families--is viewed by the Vatican as a vehicle for the enslavement rather than liberation of women. The opening of a sensitive dialogue between the Catholic Church and supporters of voluntary family planning could help couples make sound moral decisions about their families and contribute to saving the lives of millions of women, most of them poor.

  7. Did John B. Watson Really "Found" Behaviorism?

    Science.gov (United States)

    Malone, John C

    2014-05-01

    Developments culminating in the nineteenth century, along with the predictable collapse of introspective psychology, meant that the rise of behavioral psychology was inevitable. In 1913, John B. Watson was an established scientist with impeccable credentials who acted as a strong and combative promoter of a natural science approach to psychology when just such an advocate was needed. He never claimed to have founded "behavior psychology" and, despite the acclaim and criticism attending his portrayal as the original behaviorist, he was more an exemplar of a movement than a founder. Many influential writers had already characterized psychology, including so-called mental activity, as behavior, offered many applications, and rejected metaphysical dualism. Among others, William Carpenter, Alexander Bain, and (early) Sigmund Freud held views compatible with twentieth-century behaviorism. Thus, though Watson was the first to argue specifically for psychology as a natural science, behaviorism in both theory and practice had clear roots long before 1913. If behaviorism really needs a "founder," Edward Thorndike might seem more deserving, because of his great influence and promotion of an objective psychology, but he was not a true behaviorist for several important reasons. Watson deserves the fame he has received, since he first made a strong case for a natural science (behaviorist) approach and, importantly, he made people pay attention to it.

    During the early part of his career, John Archibald Wheeler made an astonishing number of contributions to nuclear and particle physics, as well as to classical electrodynamics, often in collaboration with another physicist. He was also a major contributor to the Manhattan Project (in Chicago and Hanford rather than Los Alamos), and, following World War II, became an influential scientific cold warrior. His early achievements in physics include the calculated scattering of light by light (with Gregory Breit), the prediction of nuclear rotational states (with Edward Teller), the theory of fission (with Niels Bohr), action-at-a-distance electrodynamics (with Richard Feynman), the theory of positronium, the universal weak interaction (with Jayme Tiomno), and the proposed use of the muon as a nuclear probe particle. He gained modest fame as the person who identified xenon 135 as a reactor poison. His Project Matterhorn contributed significantly to the design of the H bomb, and his Project 137, which he had hoped would flower into a major defense lab, served as the precursor to the Jason group.

    This meeting, held in the Limerick Institute of Technology, on Thursday 1 June 2006, was organised by the Munster Group of the Institute of Physics in Ireland to commemorate the life and work of John Desmond Bernal. Bernal, was born in Nenagh in 1901. Alan Mackay, who worked with Bernal at Birkbeck College coins the word 'Polytropic' to describe Bernal. He was active and hugely influential in a wide range of areas such as science, politics and society, and was instrumental in the creation of whole new areas of intellectual endeavour such as the 'science of science', molecular biology, and operations research. Andrew Brown's analogy for Bernal's mind is that 'it was like a diamond—beautifully structured, multifaceted and dazzling to behold'. In relation to Bernal, Helena Sheehan states that: 'His legacy is complex. All the more so because he was marxist in philosophy, communist in politics, polyamorous in sexuality.'. Like religion, these are areas that conventional scientists tend to shy away from or at the very least consign to very separate and often neglected 'compartments'. According to Sheehan, 'Bernal came to marxism seriously and intelligently. He found in its philosophical framework a structure in which he could live, think, create, pursue science, act politically and develop further. It opened him radically to the world, rather than closing him down or constricting him, as critics imply.'. And his contributions to science and to society are significant and enduring. Just two areas of 'his science' were addressed in some detail at this meeting. Martin Caffrey treats the area of structural biology in the context of modern developments but focusing on Bernal's role in its evolution. John Finney gives an account of Bernal's 'two bouts of activity' on the structure of water and as Bernal's last PhD student he gives unique insights on how Bernal worked and why he 'did science'. Bernal writes in response to a well wisher on his 70th birthday: 'I am sure that

With concentration we can achieve the maximum and faster result in our work. Some ways to improve concentration that being researched here is by arranging the wall color and the lamp color temperature of the room. The color used as wall color in this research was the blue 9.8B, 7.4/5.6; and the orange 8.1YR, 8.7/3.7 of the Munsell color palette. Whereas the room lighting was the fluorescent lamp in 6500K (cool daylight and 2700K (warm white color temperature. Respondents of this research were 117 undergraduate students, the average GPA was 3.28; and 20,26 years as the mean age. The concentration and cognition tests are the Army Alfa test and IST subtest 9 that conducted in the room with different condition. Found in this research that the blue with cool daylight lamp has significant impact to concentration in 2,526 Lickert scale; and that orange with cool daylight lamp has correlation 0.781 to cognition result; but the other conditions have no significancy toward concentration and cognition

    Full Text Available Since Extension agents work with a variety of families, there is a desperate need to further our understanding of how to educate diverse communities on a family-related topic. Focused on assisting those teaching marital education to a diverse population, this study attempts to understand how individual differences impact relationship satisfaction and marital communication. Based on John Gottman’s research on marital communication and John Lee’s six loves styles, 653 participants completed a survey to further understanding of the relationship between inter- and intrapersonal variables. Results revealed that marital communication and love styles accounted for 54.6% of the variance in marital satisfaction regardless of difference in demographics. Results of this study provide a resource for educators and practitioners to use with diverse clientele, while also emphasizing the need to understand both intra- and interpersonal variables when working with families.

    Directory of Open Access Journals (Sweden)

    Puyol González, Ángel

    2004-12-01

    Full Text Available One of the indisputable achievements of John Rawls work has been the revitalisation of the concept of equality in the ethics and political philosophy of the last few years. He has removed it from the monopoly of the ideologies that have had better or worse luck throughout the entire twentieth century and returned it to the analytical and conceptual rigor of philosophy. Moreover, he has done so with the added virtue of harmonising the value of equality with the values of freedom and efficiency, which is an effort that is not always valued with sufficient understanding. There is no doubt about the influence of Rawls theory of justice on current egalitarian thinking that, in some way, has been, and is still being, built -following -or diverging from the wake opened by the philosopher from Harvard. In this article, I analyse the main debates that are going on about Rawlsian egalitarianism and I point out some possible future orientation. In the first place, I set out the two great egalitarian arguments in Rawls work stemming, respectively, from a person's moral conception and the moral arbitrariness of the individual' s social and natural contingencies. Afterwards, I explore the problems of both arguments insisting, on one hand, on the inadequacy of the Kantian moral personality as a foundation for an egalitarian theory and, on the other hand, on the inconsistency of luck egalitarianism as an egalitarian extension of Rawls theory. In third place, I demonstrate that the main egalitarian problem in Rawls work comes from the concept of equality and equity void of solidarity. I conclude, finally, that justice as fairness should be contrasted with justice as fraternity.

    Uno de los logros indiscutibles de la obra de John Rawls ha sido la revitalización del concepto de igualdad en la ética y la filosofía política de los últimos años, desmonopolizándolo de las ideologías que han recorrido con mejor o peor fortuna todo el siglo xx y devolvi

    2012-01-01

    Full Text Available En el artículo se analiza cómo John Searle explica la instauración o la destrucción del poder convencional. El punto de partida es que la explicación de Searle se sustenta en la idea del poder convencional, entendido como un acontecimiento único que hace parte de la realidad social constituida por el lenguaje, lo cual permite expresar que cuando un acto de habla performativo es realizado en circunstancias apropiadas por un agente se sigue la imposición de la función de estatus al acontecimiento, la comprensión de la fuerza explicativa de las reglas constitutivas, la ejecución de poderes deónticos y la creación de un nuevo hecho institucional. No obstante, tal formulación deja por fuera la actitud de riesgo de los participantes en la creación o destrucción de los poderes que componen los hechos institucionales. Para demostrar este punto de partida, en primer lugar, se ubica el aporte filosófico de Searle sobre el lenguaje en términos de la perspectiva pragmática. En segundo lugar, se muestra que desde el lenguaje la intencionalidad colectiva impone funciones de estatus que crean formas de poderes deónticos. Para concluir, se afirma que el mantenimiento o la destrucción del poder convencional no se agota en las reglas constitutivas ni en las funciones de estatus, sino que se complementa con la actitud de riesgo desarrollarla por los participantes en el momento en que hacen uso del lenguaje. El análisis de la información recogida, mediante la reseña crítica, se realizó utilizando herramientas del enfoque metodológico reconstructivo conceptual.

    Paratuberculosis (Johne's disease) is an economically significant condition caused by Mycobacterium avium subsp. paratuberculosis. However, difficulties in diagnosis and classification of individual animals with the condition have hampered research and impeded efforts to halt its progressive spread in the global livestock industry. Descriptive terms applied to individual animals and herds such as exposed, infected, diseased, clinical, sub-clinical, infectious and resistant need to be defined so that they can be incorporated consistently into well-understood and reproducible case definitions. These allow for consistent classification of individuals in a population for the purposes of analysis based on accurate counts. The outputs might include the incidence of cases, frequency distributions of the number of cases by age class or more sophisticated analyses involving statistical comparisons of immune responses in vaccine development studies, or gene frequencies or expression data from cases and controls in genomic investigations. It is necessary to have agreed definitions in order to be able to make valid comparisons and meta-analyses of experiments conducted over time by a given researcher, in different laboratories, by different researchers, and in different countries. In this paper, terms are applied systematically in an hierarchical flow chart to enable classification of individual animals. We propose descriptive terms for different stages in the pathogenesis of paratuberculosis to enable their use in different types of studies and to enable an independent assessment of the extent to which accepted definitions for stages of disease have been applied consistently in any given study. This will assist in the general interpretation of data between studies, and will facilitate future meta-analyses.

  17. Liquid Wall Chambers

    Energy Technology Data Exchange (ETDEWEB)

    Meier, W R

    2011-02-24

    The key feature of liquid wall chambers is the use of a renewable liquid layer to protect chamber structures from target emissions. Two primary options have been proposed and studied: wetted wall chambers and thick liquid wall (TLW) chambers. With wetted wall designs, a thin layer of liquid shields the structural first wall from short ranged target emissions (x-rays, ions and debris) but not neutrons. Various schemes have been proposed to establish and renew the liquid layer between shots including flow-guiding porous fabrics (e.g., Osiris, HIBALL), porous rigid structures (Prometheus) and thin film flows (KOYO). The thin liquid layer can be the tritium breeding material (e.g., flibe, PbLi, or Li) or another liquid metal such as Pb. TLWs use liquid jets injected by stationary or oscillating nozzles to form a neutronically thick layer (typically with an effective thickness of {approx}50 cm) of liquid between the target and first structural wall. In addition to absorbing short ranged emissions, the thick liquid layer degrades the neutron flux and energy reaching the first wall, typically by {approx}10 x x, so that steel walls can survive for the life of the plant ({approx}30-60 yrs). The thick liquid serves as the primary coolant and tritium breeding material (most recent designs use flibe, but the earliest concepts used Li). In essence, the TLW places the fusion blanket inside the first wall instead of behind the first wall.

  18. John Paul Jones: An Overlooked Autopsy Finding that May Explain His Terminal Illness.

    A finding in the autopsy of John Paul Jones, the American Revolutionary War naval hero, may explain his terminal illness. During his last 2 years, he had a persistent productive cough and dyspnea. Ten days before death, he developed rapidly progressive dependent edema and ascites. He died in France in 1792. His body, preserved in alcohol in a lead coffin, was, in 1905, removed to the United States. Glomerulonephritis was noted on an autopsy, performed in France, but there was no comment then or since about ventricular wall thickness being the same in both ventricles at 5-6 mm. Hypertrophy and dilatation with biventricular failure followed by tissue shrinkage during 113 years in alcohol could have resulted in these ventricular wall findings. Systemic hypertension and left ventricular failure are consistent with his respiratory symptoms complicated perhaps by pulmonary emboli, right ventricular failure with tricuspid regurgitation, peripheral congestion, and jaundice. © 2015 American Academy of Forensic Sciences.

    2006-12-01

    Michael John Klein died on 14 May 2005 at home in South Pasadena, California. The cause of death was tongue cancer that metastasized to the lungs. He was a non-smoker. Mike was a passionate radio astronomer, a trusted astronomical observer, an educator and a family man. Mike was born on 19 January 1940 in Ames, Iowa, the son of Florence Marie (Graf) and Fred Michael Klein. His mother was a homemaker, and his father was a banker. Mike had two older sisters, Lois Jean (Klein) Flauher and Marilyn June (Klein) Griffin. In 1962, Mike married his high school sweetheart Barbara Dahlberg, who survives him along with their three children, Kristin Marie (Klein) Shields, Michael John Klein Jr., Timothy Joel Klein, and six grandchildren. Mike developed a love for astronomy early in his life, and credited an early morning, newspaper-delivery route that he had at age twelve, which took him outside well before sunrise. He told family members that as he walked along his route, he stared into the sky and wondered what everything was. He studied sky charts, located stars, and began to understand how the planets shifted their positions relative to the stars each day. Another big influence in Mike's life was his brother in-law, Jim Griffin. Jim helped Mike understand that his passion for science did not have to remain a hobby, but could and should become a career. Jim's encouragement led Mike to attend Iowa State University in Ames, where he earned a BS in electrical engineering in 1962. Mike then started graduate school in electrical engineering at Michigan State, but after one semester transferred to the University of Michigan, Ann Arbor, where he earned an MS (1966) and PhD (1968) in astronomy. His doctoral dissertation, under the direction of Professor Fred Haddock, was based on extensive observations of the planets and examined the physical and thermal properties of planetary atmospheres and surfaces. Mike was awarded a Resident Research Associate position at JPL by the National

    2007-12-01

    Professor Michael John Seaton, hailed as the "Father of Atomic Astrophysics," passed away on May 29, 2007. He was one of the few Honorary Fellows of both the American Astronomical Society and the American Physical Society, so honored for his monumental contributions to both physics and astronomy. Mike Seaton was born on January 16, 1923 in Bristol, England. He attended Wallington County High School. But his leftist political activities, even at that stage, led to his expulsion, though he was eventually allowed to matriculate. He enlisted in the Royal Air Force as a navigator during the Second World War, and flew many dangerous missions. His legendary concentration and precision are reflected in the following anecdote. Once after a bombing mission his aircraft was lost in fog over the Alps. Seaton calculated the position and coordinates in flight to guide the aircraft. When the fog lifted, the crew found themselves flying perilously close to the mountains, but made it safely back. His associates often said, "A Seaton calculation is carried out as if his life depended on it." After the War he was admitted to University College London (UCL) as an undergraduate. Thereafter, he spent all of his professional career at UCL. Seaton received his Batchelor's degree in 1948, and his Ph.D. in 1951. His tenure at UCL coincided with the golden age of atomic astrophysics, for he was largely responsible for it. Seaton was elected Fellow of the Royal Society in 1967, and as President of the Royal Astronomical Society (RAS) in 1978. He was the recipient of an Honorary Doctorate from the Observatoire de Paris, an Honorary D.Sc. from the Queen's University of Belfast, the Gold Medal for Astronomy by the RAS, the Guthrie Medal by the Institute of Physics, the Royal Society Hughes award for lifetime work by the RAS, and several other prestigious awards. Nevertheless, as Alex Dalgarno recently remarked, Seaton was not part of the establishment because he chose not to be. Though rooted in

  1. John Calvin and John Locke on the Sensus Divinitatis and Innatism

    Directory of Open Access Journals (Sweden)

    Full Text Available Inheritors of the Calvinist Reformed tradition have long disagreed about whether knowledge of God’s nature and existence can be or need be acquired inferentially by means of the standard arguments of natural theology. Nonetheless, they have traditionally coalesced around the thought that some sense or awareness of God is naturally implanted or innate in human beings. A root of this orientation can be found in John Calvin’s discussion of the sensus divinitatis in the first book of The Institutes of the Christian Religion. This paper outlines a pedagogical strategy for organizing and evaluating Calvin’s treatment of the sensus divinitatis, chiefly by putting it in tension with John Locke’s polemic against innatism in Book I of An Essay concerning Human Understanding. I begin by reconstructing Calvin’s depiction of the sensus divinitatis, as well as his case for thinking that it is innate. I then explain how Locke’s critique of innatism offers a fairly direct response to Calvin and, hence, a useful framework for exploring the limits of Calvin’s treatment of the sensus divinitatis.

    John Goronwy Jones Gron Jones, as he was known to all, was a champion of Physics Education and his death, shortly before his eightieth birthday, robbed physics teachers of a colleague who fought many battles on their behalf. He was not shy of taking issue with anyone in authority who might be putting forward policies which would harm his great love: Physics Education and Physics Teaching. His photograph shows a man with an impish grin, looking friend and foe alike straight in the eye, before delivering the death blow to an argument which was founded on less than common sense. At other times he would listen patiently to the woes of colleagues before offering them fatherly/grandfatherly advice so that whoever was on the receiving end would go away feeling better for the encounter. Gron was born in Swansea and educated at Lewis Boys Grammar School in Glamorgan before entering University College Cardiff first of all as a mathematician before graduating in Physics in 1941. After his war service in the RAF, working on signals and radar development, he returned to do an MSc in X-ray crystallography before completing a PGCE in Bristol. What then passed for teacher training in all institutions left him wary of returning to train teachers himself but after 14 years spent teaching physics in three schools he returned to Cardiff and began a 25 year career in teacher training. He and his two colleagues, Clifford Othen (chemistry) and Douglas Hillier (biology) built up the Cardiff Science Centre as a focus for initial and in-service science teacher training in South Wales. The triumvirate was well known and a power to be reckoned with. They created links between the University Science Departments and the Schools. Gron knew the local schools and their physics teachers intimately. Cardiff became a focus for science education both nationally and internationally. He was a frequent attender at both ICPE (International Commission for Physics Education) and GIREP (International Physics

    2011-12-01

    John P. Oliver, an emeritus professor of astronomy at the University of Florida in Gainesville, passed away Thursday, February 10, 2011, after a courageous and long battle with renal cancer. He left behind memories of a life and career to envy. During his forty years of service to his profession and department, this unique astronomer distinguished himself as a research scientist and instrumentalist, creative software designer, gifted teacher and speaker, a vocal advocate of public outreach, and friend to all who knew him. Oliver was born in New Rochelle, New York, during late fall 1939 on November 24. His father, James P. Oliver, was a naval officer and his mother was the former Dorothy Armstrong Cambell. Oliver's early days were spent in various cities due to his father's military life but he eventually received a high school diploma from Princess Ann High School in Virginia. Oliver subsequently graduated with a bachelor of science degree in physics in 1963 from the prestigious Rensselaer Polytechnic Institute in Troy. Lick Observatory awarded him a graduate assistantship so he moved west to California where he met and, on November 2, 1963, married Barbara Kay McKenna, who became his lifelong love and partner. In California Oliver had the good fortune to work with several eminent astronomers. This included Albert E. Whifford, director of Lick Observatory and known for his work on interstellar reddening, and Merle F. Walker, an expert in photometry, who also helped establish Pluto's rotation period. His close relation with Lawrence H. Aller, one of the 20th century's memorable astronomers, known for his ability to combine observation, theory and education, and for his care and kindness, helped bind Oliver and astronomy together for life. Oliver would also join the technical staff of the Aerospace Corporation, become an acting director of the Pine Mountain Observatory (University of Oregon), and a research assistant at the University of California in Los Angeles

    2004-12-01

    John Beverley (Bev) Oke passed away of heart failure early on 2 March 2004 at his Victoria, B.C. home. Bev's insatiable scientific curiosity led to fundamental contributions in many areas of stellar and extragalactic astronomy, including the development of advanced instrumentation for the largest optical telescopes and the mentoring of scores of grateful students and colleagues. Bev Oke was born in Sault Ste. Marie, ON, Canada on 23 March 1928, the son of Lyla Parteshuk and the Rev. C. Clare Oke. He entered the University of Toronto in 1945 to study physics with a steadily increasing fraction of astronomy, receiving his BA in 1949. Summer employment at the David Dunlap Observatory (DDO, 1948) and at the Dominion Observatory (Ottawa, 1949, 1950) sealed his interest in astronomy as a career. For his MA thesis (1950, Toronto), performed under theoretician Ralph Williamson, he made interior models of the Sun, and was proud to have proved that the proton-proton cycle was indeed the source of solar energy. Upon entering Princeton University he worked with Martin Schwarzschild on stellar interiors models and Lyman Spitzer on interstellar lines. A lifelong friendship with Alan Sandage began during Bev's second year while Alan was a post-doc at Princeton. During Bev's third year he spent three months in Pasadena with Lyman obtaining data for his thesis on Of stars. While in Pasadena he began a second life-long collaboration with Jesse Greenstein, an astronomer whose approach to science Bev deeply respected. In the small field of astronomy in that era, Bev wrote to DDO Director Jack Heard indicating the nearing completion of his PhD studies and his interest in a position. This led to a lectureship at the University of Toronto (1953-1956), followed by an Assistant Professorship (1956-1958). Bev's interest in instruments began at this time, when he built a device to convert photographic density to intensity, and worked with DDO engineer-machinist Jerry Longworth to implement

  16. Anamnesis and the Silent Narrator in Plato and John

    Directory of Open Access Journals (Sweden)

    George L. Parsenios

    2017-03-01

    Full Text Available The Gospel of John is often compared to the dialogues of Plato by those who connect Johannine theology and Platonic philosophy. The comparison operates on the level of ideas. The present paper does not ignore issues of theology and philosophy but grounds a comparison of John and Plato first and foremost on the literary level. In several key places in John 1, 3, and 14, the Johannine narrator recedes from view and is unexpectedly silent where one would expect a narrator’s comment to organize the conversations and interactions between characters in John. Plato also renders the voice of the narrator silent in a dialogue like the Theaetetus. This paper argues that John and Plato both suppress the narrator’s voice in order to further their anamnetic efforts and to make later generations not only readers but participants in their original conversations.

    The plasma wall interactions for two extreme cases, the 'vacuum model' and the 'cold gas blanket' are outlined. As a first step for understanding the plasma wall interactions the elementary interaction processes at the first wall are identified. These are energetic ion and neutral particle trapping and release, ion and neutral backscattering, ion sputtering, desorption by ions, photons and electrons and evaporation. These processes have only recently been started to be investigated in the parameter range of interest for fusion research.

    Behrisch, R.

    1976-01-01

    Some of the relevant elementary atomic processes which are expected to be of significance to the first wall of a fusion reactor are reviewed. Up to the present, most investigations have been performed at relatively high ion energies, typically E greater than 5 keV, and even in this range the available data are very poor. If the plasma wall interaction takes place at energies of E greater than 1 keV the impurity introduction and first wall erosion which will take place predominantly by sputtering, will be large and may severely limit the burning time of the plasma. The wall bombardment and surface erosion will presumably not decrease substantially by introducing a divertor. The erosion can only be kept low if the energy of the bombarding ions and neutrals can be kept below the threshold for sputtering of 1 to 10 eV. 93 refs

    The dynamic wall concept is a ventilation strategy that can be applied to a single family dwelling. With suitable construction, outside air can be admitted through the exterior walls of the house to the interior space to function as ventilation air. The construction and performance monitoring of a demonstration house built to test the dynamic wall concept in Sherwood Park, Alberta, is described. The project had the objectives of demonstrating and assessing the construction methods; determining the cost-effectiveness of the concept in Alberta; analyzing the operation of the dynamic wall system; and determining how other components and systems in the house interact with the dynamic wall. The exterior wall construction consisted of vinyl siding, spun-bonded polyolefin-backed (SBPO) rigid fiberglass sheathing, 38 mm by 89 mm framing, fiberglass batt insulation and 12.7 mm drywall. The mechanical system was designed to operate in the dynamic (negative pressure) mode, however flexibility was provided to allow operation in the static (balanced pressure) mode to permit monitoring of the walls as if they were in a conventional house. The house was monitored by an extensive computerized monitoring system. Dynamic wall operation was dependent on pressure and temperature differentials between indoor and outdoor as well as wind speed and direction. The degree of heat gain was found to be ca 74% of the indoor-outdoor temperature differential. Temperature of incoming dynamic air was significantly affected by solar radiation and measurement of indoor air pollutants found no significant levels. 4 refs., 34 figs., 11 tabs.

    A total of 59 cases of mild facial fractures (simple orbital wall fractures, 34 cases, other facial fractures, 25 cases) with the clinical suspects of orbital wall fractures were evaluated both by conventional views (Waters' and Caldwell views) and coronal CT scans. Conventional views were obtained, as an average, after 4 days and CT after 7 days of injuries. Both the medial wall and the floor were evaluated at two sites, i.e., anterior and posterior. The ethmoid-maxillary plate was also included in the study. The degree of fractures was classified as, no fractures, fractures of discontinuity, dislocation and fragmentation. The coronal CT images in bone window condition was used as reference and the findings were compared between conventional views and CT. The correct diagnosis was obtained as follows: orbital floor (anterior, 78%, posterior, 73%), medial orbital wall (anterior, 72%, posterior, 72%) and ethmoid-maxillary plate (64%). The false positive diagnosis was as follows: orbital floor (anterior only, 13%), medial orbital wall (anterior only, 7%) and ethmoid-maxillary plate (11%). The false negative diagnosis was as follows: orbital floor (anterior, 9%, posterior, 10%), medial orbital wall (anterior, 21%, posterior, 28%) and ethmoid-maxillary plate (21%). The results were compared with those of others in the past. (author)

  4. Raman Identification of Pigments in Wall Paintings of the Colonial Period from Bolivian Churches in the Ruta De La Plata

    Directory of Open Access Journals (Sweden)

    2018-03-01

    Full Text Available Micro-Raman spectroscopy was used to analyze and identify pigments and determine the palette of color in wall paintings from four churches of the Colonial Period, in the Bolivian highlands. The ancient churches Santiago de Callapa, Curahuara de Carangas, NuestraSeñora de Copacabana de Andamarca and San José de Soracachi were constructed during the 17th and 18th centuries, around the important colonial Ruta de la Plata, between Potosí city and Arica harbor on the Pacific coast of South America. Most pigments used in the wall paintings correspond to inorganic minerals as well as to organic colorants. Fully chlorinated copper phthalocyanine (green, copper phthalocyanine (blue, β-naphthol (yellow and benzoimidazolone (red, were identified in the corresponding colored areas suggesting subsequent recent interventions or restorations. Ground layer materials were also characterized. The present results allow for discussion of the pictorial techniques used in the Andean highland during the colonial period and allow conservators and restorers to make important decisions regarding the type of intervention to perform in the case of these important historical and patrimonial monuments.

  5. Romano-British wall paintings: Raman spectroscopic analysis of fragments from two urban sites of early military colonisation

    2009-08-01

    Raman spectroscopic analyses of 1st century AD Romano-British villa wall-painting fragments from two important military and early urban centres at Colchester and Lincoln have demonstrated some interesting contrasts in technique and palette usage. Colchester, the earliest fortified settlement, developed a sophisticated painting and craft industry compared with Lincoln in the assimilation of novel substrate preparation ideas and pigment adoption. The earliest use of the rather rare purple mineral pigment, caput mortuum, hitherto reported in only a few Roman villas elsewhere in mainland Europe, is in evidence in this early phase settlement and the use of gypsum as a special ground preparation agent as an additive to the more common limewash putty to enhance the effect of the use of lazurite as a pigment is worthy of note in this context. Otherwise, the pigments are seen to be those that are quite normally encountered in Roman villas, namely, haematite, goethite, terre verte, and carbon. The results of this study indicate that at Colchester there was a continued development in technique into the colonial phase compared with a stagnation in Lincoln; these scientific results have created a stimulus for further historical research into pigment and techniques development for wall paintings at the fringe of the Roman Empire in the 1st-3rd Centuries AD.

  19. First John structure resolved: Exegetical analysis, Part 2

    Directory of Open Access Journals (Sweden)

    Ron J. Bigalke

    2013-11-01

    Full Text Available Numerous attempts have been suggested regarding the structure of First John. The only nearly unanimous agreement amongst commentators is concerning the prologue (1:1–4 and the conclusion (5:13–21. The lack of unanimity can be frustrating for the majority of those who seek to understand the macrostructure of the First Epistle of John. Consequentially, some commentators have opined that it is impossible to determine a notable structure of First John, and the epistle is thus regarded as a relatively imprecise series of various thoughts that were composed on the basis of mere association. Many exegetes have therefore proposed suggested outlines to aid the understanding of First John as opposed to providing genuine efforts to articulate a discernable structure of the epistle. The final part of this exegetical analysis seeks to demonstrate that exegetes need not succumb to such pessimism because there does appear to be a discernable structure to First John. Providing and stating resolve concerning the First John structure is fundamental for understanding the revealed contents of the epistle.

  1. Kinetic wall from Israel

    Energy Technology Data Exchange (ETDEWEB)

    Godolphin, D.

    1985-05-01

    An unusual solar mass wall is described. At the turn of a handle it can change from a solar energy collector to a heat-blocker. An appropriate name for it might be the rotating prism wall. An example of the moving wall is at work in an adobe test home in Sede Boqer. Behind a large south-facing window stand four large adobe columns that are triangular in plan. One face of each of them is painted black to absorb sunlight, a second is covered with panels of polystyrene insulation, and a third is painted to match the room decor. These columns can rotate. On winter nights, the insulated side faces the glass, keeping heat losses down. The same scheme works in summer to keep heat out of the house. Small windows provide ventilation.

    The orbital debris, space surveillance, and astronomical communities lost a valued and beloved friend when John L. Africano passed away on July 27, 2006, at the young age of 55. John passed away in Honolulu, Hawaii, from complications following a heart attack suffered while playing racquetball, which was his avocation in life. Born on February 8, 1951, in Saint Louis, Missouri, John graduated with a B.S. in Physics from the University of Missouri at Saint Louis in 1973, and received a Master's degree in Astronomy from Vanderbilt University in 1974. John had a real love for astronomical observing and for conveying his many years of experience to others. He encouraged many young astronomers and mentored them in the basics of photometry and astronomical instrumentation. John was author or co-author on nearly one-hundred refereed publications ranging from analyses of cool stars to the timing of occultations to space surveillance. He was honored for his contributions to minor planet research when the Jet Propulsion Laboratory named Minor Planet 6391 (Africano) after him. John held operational staff positions at several major observatories including McDonald Observatory in Texas, Kitt Peak National Observatory in Arizona, and the Cloudcroft Telescope Facility in New Mexico. He observed at numerous observatories worldwide, including Cerro Tololo Inter-American Observatory (CTIO) in Chile, developing a world-wide network of friends and colleagues. John's ability to build diverse teams through his managerial and technical skills, not to mention his smiling personality, resulted in numerous successes in the observational astronomy and space surveillance arenas. As an astronomer for Boeing LTS Inc., he worked for many years at the Advanced Maui Optical and Space Surveillance site (AMOS) on Maui, Hawaii, where he contributed his operational and instrumental expertise to both the astronomy and space surveillance communities. He was also the co-organizer of the annual AMOS

    2005-01-01

    A 2.34 m sediment profile from the base of the crater of Mt St John volcano (a small basaltic cone on Auckland Isthmus) provides a partial environmental record of the Late Quaternary. The record highlights potential age control problems with sediment cores taken directly from archaeological sites. Two distal tephras were recorded: 9.5 ka Rotoma and 7 ka Tuhua. A date of 16 309 ± 90 14 C yr BP from the basal scoria of the profile provides a minimum date for the eruption of Mt St John. Pollen was present only in the upper 0.33 m of the profile, in a layer of peat and soil which caps highly weathered silts and clays eroded from the crater walls. In early Polynesian times (most likely after c. 800 14 C yr BP), vegetation of the crater swamp was dominated by Cyperaceae sedges and Paesia ground fern. Dacrycarpus trees were also present. Podocarp-hardwood forest, dominated by Metrosideros, grew on the rim and inner slopes of the crater. Elaeocarpus, Griselinia, and Cyathea were also present. A decline in Dacrycarpus pollen and an accelerated erosion rate mark Polynesian forest clearance within the crater. Typha became a major component of the swamp vegetation during the Late Polynesian-European era. (author). 30 refs., 5 figs., 2 tabs

  9. Chronic Abdominal Wall Pain.

    Koop, Herbert; Koprdova, Simona; Schürmann, Christine

    2016-01-29

    Chronic abdominal wall pain is a poorly recognized clinical problem despite being an important element in the differential diagnosis of abdominal pain. This review is based on pertinent articles that were retrieved by a selective search in PubMed and EMBASE employing the terms "abdominal wall pain" and "cutaneous nerve entrapment syndrome," as well as on the authors' clinical experience. In 2% to 3% of patients with chronic abdominal pain, the pain arises from the abdominal wall; in patients with previously diagnosed chronic abdominal pain who have no demonstrable pathological abnormality, this likelihood can rise as high as 30% . There have only been a small number of clinical trials of treatment for this condition. The diagnosis is made on clinical grounds, with the aid of Carnett's test. The characteristic clinical feature is strictly localized pain in the anterior abdominal wall, which is often mischaracterized as a "functional" complaint. In one study, injection of local anesthesia combined with steroids into the painful area was found to relieve pain for 4 weeks in 95% of patients. The injection of lidocaine alone brought about improvement in 83-91% of patients. Long-term pain relief ensued after a single lidocaine injection in 20-30% of patients, after repeated injections in 40-50% , and after combined lidocaine and steroid injections in up to 80% . Pain that persists despite these treatments can be treated with surgery (neurectomy). Chronic abdominal wall pain is easily diagnosed on physical examination and can often be rapidly treated. Any physician treating patients with abdominal pain should be aware of this condition. Further comparative treatment trials will be needed before a validated treatment algorithm can be established.

    One of the Pacific Northwest's most notable outdoor recreation areas, the "John Day Country" in northeastern Oregon, is named after a native Virginian who was a member of the Astor expedition to the mouth of the Columbia River in 1812. There is little factual information about John Day except that he was born in Culpeper County, Virginia, about 1770. It is known also that in 1810 this tall pioneer "with an elastic step as if he trod on springs" joined John Jacob Astor's overland expedition under Wilson Price Hunt to establish a vast fur-gathering network in the Western States based on a major trading post at the mouth of the Columbia River.

  11. Geology of St. John, U.S. Virgin Islands

    Science.gov (United States)

    Rankin, Douglas W.

    2002-01-01

    The rocks of St. John, which is located near the eastern end of the Greater Antilles and near the northeastern corner of the Caribbean plate, consist of Cretaceous basalt, andesite, keratophyre, their volcaniclastic and hypabyssal intrusive equivalents, and minor calcareous rocks and chert. These rocks were intruded by Tertiary mafic dikes and tonalitic plutons. The oldest rocks formed in an extensional oceanic environment characterized by abundant keratophyre and sheeted dikes. Subduction-related volcanism of the east-west-trending marine Greater Antilles volcanic arc began on St. John near the transition between the Early and Late Cretaceous. South-directed compression, probably caused by the initial collision between the Greater Antilles arc of the Caribbean plate and the Bahama platform of the North American plate, deformed the Cretaceous strata into east-west-trending folds with axial-plane cleavage. Late Eocene tonalitic intrusions, part of the Greater Antilles arc magmatism, produced a contact aureole that is as much as two kilometers wide and that partly annealed the axial-plane cleavage. East-west compression, possibly related to the relative eastward transport of the Caribbean plate in response to the beginning of spreading at the Cayman Trough, produced long-wavelength, low-amplitude folds whose axes plunge gently north and warp the earlier folds. A broad north-plunging syncline-anticline pair occupies most of St. John. The last tectonic event affecting St. John is recorded by a series of post-late Eocene sinistral strike-slip faults related to the early stages of spreading at the Cayman Trough spreading center and sinistral strike-slip accommodation near the northern border of the Caribbean plate. Central St. John is occupied by a rhomb horst bounded by two of these sinistral faults. Unlike other parts of the Greater Antilles, evidence for recent tectonic movement has not been observed on St. John.

  13. Process and progress: John Hughlings Jackson's philosophy of science.

    Science.gov (United States)

    Jacyna, L Stephen

    2011-10-01

    Some scepticism has been voiced over whether the work of John Hughlings Jackson possesses any significant philosophical orientation. This article argues that Hughlings Jackson was acquainted with the work of a wide range of philosophers. In particular, certain aspects of the writings of John Stuart Mill are reflected in Hughlings Jackson's own work. From early in his career, Hughlings Jackson adopted a critical stance in his neurological papers, seeking to expose shortcomings in the conventional practices of his peers and urging greater methodological rigour and sophistication in order to advance their science. This critical and 'procedurist' bias endows Hughlings Jackson's writings with a characteristically modern character.

    Energy Technology Data Exchange (ETDEWEB)

    Kostek, P.T.

    1987-08-11

    In a channel specially designed to fasten semi-rigid mineral fibre insulation to masonry walls, it is known to be constructed from 20 gauge galvanized steel or other suitable material. The channel is designed to have pre-punched holes along its length for fastening of the channel to the drywall screw. The unique feature of the channel is the teeth running along its length which are pressed into the surface of the butted together sections of the insulation providing a strong grip between the two adjacent pieces of insulation. Of prime importance to the success of this system is the recent technological advancements of the mineral fibre itself which allow the teeth of the channel to engage the insulation fully and hold without mechanical support, rather than be repelled or pushed back by the inherent nature of the insulation material. After the insulation is secured to the masonry wall by concrete nail fastening systems, the drywall is screwed to the channel.

    Full Text Available Abstract Friends and colleagues remember John N. Brady, Ph.D., Chief of the Virus Tumor Biology Section of the Laboratory of Cellular Oncology, who died much too young at the age of 57 on April 27, 2009 of colon cancer. John grew up in Illinois and received his Ph.D. with Dr. Richard Consigli at Kansas State University studying the molecular structure of polyomavirus. In 1984 John came to the National Institutes of Health as a Staff Fellow in the laboratory of Dr. Norman Salzman, Laboratory of Biology of Viruses NIAID, where he was among the first to analyze SV40 transcription using in vitro transcription systems and to analyze regulatory sequences for SV40 late transcription. He then trained with Dr. George Khoury in the Laboratory of Molecular Virology NCI, where he identified SV40 T-antigen as a transcriptional activator protein. His research interests grew to focus on the human retroviruses: human T-cell lymphotropic virus type I (HTLV-I and human immunodeficiency virus (HIV, analyzing how interactions between these viruses and the host cell influence viral gene regulation, viral pathogenesis and viral transformation. His research also impacted the fields of eukaryotic gene regulation and tumor suppressor proteins. John is survived by his wife, Laraine, and two sons, Matt and Kevin.

    Banks, Richard C.

    1997-01-01

    John Aldrich was born in Providence, Rhode Island, on 23 February 1906, and went to the Providence public schools. He developed a broad interest in natural history at an early age, being stimulated by his mother, a kindergarten teacher, who introduced him to nature books. His interest was strengthened by Harold L. Madison, Director of the Park Museum in Providence, an Associate ( = member) of the AOU. As a high school student, John taught nature study at the Rhode Island Boy Scout Camp in summers. John was President of his class at Classical High School, and manager of the school's football team in his senior year. Also in that year, 1923, John published his first paper, a note in Bird-Lore on the occurrence of the Mockingbird in Rhode Island. That paper is a literary gem, showing that his skill in writing developed as early as his knowledge of birds. His early interest in football continued as well; he was a devoted fan of the Washington Redskins in his later years.

    Shining light through walls? At first glance this sounds crazy. However, very feeble gravitational and electroweak effects allow for this exotic possibility. Unfortunately, with present and near future technologies the opportunity to observe light shining through walls via these effects is completely out of question. Nevertheless there are quite a number of experimental collaborations around the globe involved in this quest. Why are they doing it? Are there additional ways of sending photons through opaque matter? Indeed, various extensions of the standard model of particle physics predict the existence of new particles called WISPs - extremely weakly interacting slim particles. Photons can convert into these hypothetical particles, which have no problems to penetrate very dense materials, and these can reconvert into photons after their passage - as if light was effectively traversing walls. We review this exciting field of research, describing the most important WISPs, the present and future experiments, the indirect hints from astrophysics and cosmology pointing to the existence of WISPs, and finally outlining the consequences that the discovery of WISPs would have.

    Microfluidics has great potential, but the complexity of fabricating and operating devices has limited its use. Here we describe a method - Freestyle Fluidics - that overcomes many key limitations. In this method, liquids are confined by fluid (not solid) walls. Aqueous circuits with any 2D shape are printed in seconds on plastic or glass Petri dishes; then, interfacial forces pin liquids to substrates, and overlaying an immiscible liquid prevents evaporation. Confining fluid walls are pliant and resilient; they self-heal when liquids are pipetted through them. We drive flow through a wide range of circuits passively by manipulating surface tension and hydrostatic pressure, and actively using external pumps. Finally, we validate the technology with two challenging applications - triggering an inflammatory response in human cells and chemotaxis in bacterial biofilms. This approach provides a powerful and versatile alternative to traditional microfluidics.The complexity of fabricating and operating microfluidic devices limits their use. Walsh et al. describe a method in which circuits are printed as quickly and simply as writing with a pen, and liquids in them are confined by fluid instead of solid walls.

  5. The manifesto as genre in Ibsen's John Gabriel Borkman

    Directory of Open Access Journals (Sweden)

    Christine Korte

    2015-02-01

    Full Text Available This article examines John Gabriel Borkman’s neo-aristocratic performance of power and authority in Ibsen’s eponymously titled play (1896. After his downfall, John Gabriel has retreated into his once grand reception hall wherein he has become like a petrified relic from a preceding era. His performance within the “fading glory” of the upstairs hall– a veritable theatre for his delusions of grandeur – is one of an outmoded type of bourgeois “hero” whose flagrantly illicit dealings are no longer tenable as capitalism becomes ever-more “rational” and bureaucratic in its façade. The article focuses on John Gabriel’s performance of a “sovereign” or charismatic authority and examines his future visions as “manifestos”. The manifesto is a form belonging to a feudal era of rule by divine right – one that is necessarily “theatrical” in its performance of a legitimate authority. Assuming the voice of the sovereign, John Gabriel attempts to address the needs of the iron-ore miners – a desiring, albeit latent force in Ibsen’s text. The desires of the workers, however, are continually effaced by the bewitching powers of capitalist abstraction, which account for the alienation of family and individuals in Ibsen’s play.   Comparing John Gabriel’s manifesto with Marx and Engels’ Communist Manifesto not only accounts for the end of an age of neo-aristocratic bourgeois decadence, but also marks labour as the definitive socio-political issue of the late 19th century. Where John Gabriel uses a dramaturgy rooted in past models of rule to address the workers in his vision of a benevolent “kingdom”, the Communist Manifesto heralds the death of his class and replaces the voice of the “sovereign authority” with the self-authorising voice of the workers themselves. Borkman’s fatal flaw then is failing to sufficiently address the plight of the iron-ore miners with whom he claims intimate acquaintance but with whom

  9. Regulation of cell wall biosynthesis.

    Science.gov (United States)

    Zhong, Ruiqin; Ye, Zheng-Hua

    2007-12-01

    Plant cell walls differ in their amount and composition among various cell types and even in different microdomains of the wall of a given cell. Plants must have evolved regulatory mechanisms controlling biosynthesis, targeted secretion, and assembly of wall components to achieve the heterogeneity in cell walls. A number of factors, including hormones, the cytoskeleton, glycosylphosphatidylinositol-anchored proteins, phosphoinositides, and sugar nucleotide supply, have been implicated in the regulation of cell wall biosynthesis or deposition. In the past two years, there have been important discoveries in transcriptional regulation of secondary wall biosynthesis. Several transcription factors in the NAC and MYB families have been shown to be the key switches for activation of secondary wall biosynthesis. These studies suggest a transcriptional network comprised of a hierarchy of transcription factors is involved in regulating secondary wall biosynthesis. Further investigation and integration of the regulatory players participating in the making of cell walls will certainly lead to our understanding of how wall amounts and composition are controlled in a given cell type. This may eventually allow custom design of plant cell walls on the basis of our needs.

    In extensions of the Standard Model with extra scalars, the electroweak phase transition can be very strong, and the bubble walls can be highly relativistic. We revisit our previous argument that electroweak bubble walls can 'run away,' that is, achieve extreme ultrarelativistic velocities γ ∼ 10{sup 14}. We show that, when particles cross the bubble wall, they can emit transition radiation. Wall-frame soft processes, though suppressed by a power of the coupling α, have a significance enhanced by the γ-factor of the wall, limiting wall velocities to γ ∼ 1/α. Though the bubble walls can move at almost the speed of light, they carry an infinitesimal share of the plasma's energy.

  11. Nietzsche, autobiography, history: mourning and Martin and John.

    Science.gov (United States)

    Champagne, J

    1998-01-01

    How might gay and lesbian literature be read not as a mimetic representation of homosexuality, but as an activity linked to problems of subjectivity and historiography? Reading Dale Peck's novel Martin and John alongside passages from Friedrich Nietzsche's "On the Uses and Disadvantages of History for Life" and Sigmund Freud's "Mourning and Melancholia," this essay argues for an understanding of Peck's text as an attempt to link two apparently different processes of import to contemporary gay male subjects in particular: the writing of what Nietzsche terms "critical history," and the mourning of those lost to HIV disease. It concludes by linking Martin and John to feminist critiques of identity and traditional historiography, as well as noting the connection between these two critiques.

The study produced several findings: First, human beings according to Ibn Khaldun as a creation of God with all the potential fitted to the five senses and intellect become intellect. The purpose of education opens the mind and maturity of the individual to the advancement of religious, industrial and social system. Material teaching is as educational planning. The method is to advocate phasing method, repetition, widya-tours and training (practice. Secondly, according to John Dewey man is a subject that has the ability, strength, personality, and existence who are capable of changing realities. The goal of education is only to gain happiness in the world life. The method of education is including problem solving, learning by doing and discipline. Third, the thought of Ibn Khaldun is much more religious because it is influenced by its control logic in religious knowledge, so that emphazises more on human spirituality in building civilization. While John Dewey is more radical and extreme, He proposed progressive education which strives against traditional teaching authority. Both Ibn Khaldūn dan Dewey are arise from inhuman socio-cultural environment and recognize the existence of human existence with nature and humanity impulse.

  2. John Archibald Wheeler: A study of mentoring in modern physics

    Science.gov (United States)

    Christensen, Terry M.

    This dissertation has two objectives. The first objective is to determine where best to situate the study of mentoring (i.e. the 'making of scientists') on the landscape of the history of science and science studies. This task is accomplished by establishing mentoring studies as a link between the robust body of literature dealing with Research Schools and the emerging scholarship surrounding the development, dispersion, and evolution of pedagogy in the training of twentieth century physicists. The second, and perhaps more significant and novel objective, is to develop a means to quantitatively assess the mentoring workmanship of scientific craftsmen who preside over the final stages of preparation when apprentices are transformed into professional scientists. The project builds upon a 2006 Master's Thesis that examined John Archibald Wheeler's work as a mentor of theoretical physicists at Princeton University in the years 1938--1976. It includes Wheeler's work as a mentor at the University of Texas and is qualitatively and quantitatively enhanced by virtue of the author having access to five separate collections with archival holdings of John Wheeler's papers and correspondence, as well as having access to thirty one tape recorded interviews that feature John Wheeler as either the interviewee or a prominent subject of discussion. The project also benefited from the opportunity to meet with and gather background information from a number of John Wheeler's former colleagues and students. Included in the dissertation is a content analysis of the acknowledgements in 949 Ph.D. dissertations, 122 Master's Theses, and 670 Senior Theses that were submitted during Wheeler's career as an active mentor. By establishing a census of the students of the most active mentors at Princeton and Texas, it is possible to tabulate the publication record of these apprentice groups and obtain objective measures of mentoring efficacy. The dissertation concludes by discussing the wider

    John Allen Paulos at minimum gave the Numeracy movement a name through his book Innumeracy: Mathematical Illiteracy and Its Consequences. What may not be so obvious was Paulos’ strong interest in the relationship between mathematics and mathematicians on the one hand and humor and stand-up-comedian joke structures on the other. Innumeracy itself could be seen as a typically mathematical Gotcha joke on American culture generally. In this perspective, a Minnesotan acculturated to Minnesota-Nice...

  7. Electromagnetic noise spectrum at John TS [transmission station

    1992-01-01

    Canadian National (CN) is proposing the development of a commercial office tower on a site directly south of John Transmission Station (TS). CN is concerned about the potential effects of fields originating from John TS and other nearby sources on the operation of sensitive equipment and occupants of the building. Potential equipment and tenants might include data processing equipment and television and radio broadcasting companies. A study was conducted to characterize the severity of the electromagnetic environment at the site in order to address these concerns. Measurements of the electromagnetic spectrum from 100 kHz to 300 MHz were performed from a mobile test facility that features a 5 kW diesel generator and an extendible antenna mast. Peak measurements were made using a selectable measurement time of 0.05 s. It was found that the highest noise levels result from micro-gap discharges under dry weather conditions. The micro-gap discharges are characteristic of defect noise sources associated with substation hardware. At 0.5 MHz the noise levels are typical of median noise levels expected for the International Radio Consultive Committee (CCIR) defined business environment. At 74 MHz the noise levels are more severe than the expected levels for this type of environment. However, levels more representative of the business environment will be achieved by eliminating the micro-gap noise sources attributed to John TS. 6 refs., 11 figs., 2 tabs

  8. The Urgency for Peace in Teachings of John Paul II

    Directory of Open Access Journals (Sweden)

    Jerzy Lewandowski

    2014-04-01

    Full Text Available Peace has always been a topic of great importance. Its presence is desired by all nations and societies. It brings the world together in unity. John Paul II considered peace to be an integral part in creation of an independent and healthy society. Papal encyclicals and messages, intended to present the response of the teaching Church to problems that arise from time to time, often dwell on the principles that advocate peace. Since freedom and peace are in many cases a privilege for many nations, the mentioned pope commits himself to speak about the cruelty and evilness of wars and national conflicts. Pope John Paul II denounces intolerance as denial of freedom for many people, and consequently a great threat to peace. The pope teaches that peace has its roots in the family. Yet, in many societies, the family is deprived of the utmost importance that it certainly deserves. Without the adequate means for a decent livelihood, families can experience hardship in committing themselves to promote solidarity and a proper social fabric worthy of human dignity. For John Paul II, a nation’s freedom and peace are safeguarded and promoted through particular attention and a much-devoted effort by strong and healthy families.

  9. The ethical implications of 2 John 10�11

    2015-03-01

    Full Text Available The imperative in 2 John 10�11 not to receive a visitor with a false doctrine into one�s house is one of the most controversial prohibitions in the New Testament, especially in light of the commandment of love, ancient hospitality conventions, and modern-day expectations of open discussion. This raises the question what this prohibition is specifically about and whether hospitality is really asked for. This question is considered in some detail in this article. A widely held view is that the prohibition in 2 John 10 is not in line with generally accepted Christian ethics, since it militates against the attitude of love, care, and hospitality. This view is dominant in commentaries. This article aims at countering this view by proposing that the issue is not hospitality but endangering the identity and tradition of the group. This should be regarded as a positive Christian value.Intradisciplinary and/or interdisciplinary implications: I challenge theological readings of 2 John 10�11 that regard the text as unchristian in its exhortation. The results of the research show that hospitality is not the communicative centre of the text, but protection of the group, which was a common feature, not only in Christianity, but also in the ancient world in general. The future discourse should now move from focusing on moral issues related to hospitality to issues related to preserving tradition within a religion.

  10. Enhanced wall pumping in JET

    International Nuclear Information System (INIS)

    Ehrenberg, J.; Harbour, P.J.

    1991-01-01

    The enhanced wall pumping phenomenon in JET is observed for hydrogen or deuterium plasmas which are moved from the outer (larger major radius) limiter position either to the inner wall or to the top/bottom wall of the vacuum vessel. This phenomenon is analysed by employing a particle recycling model which combines plasma particle transport with particle re-emission from and retention within material surfaces. The model calculates the important experimentally observable quantities, such as particle fluxes, global particle confinement time, plasma density and density profile. Good qualitative agreement is found and, within the uncertainties, the agreement is quantitative if the wall pumping is assumed to be caused by two simultaneously occurring effects: (1) Neutral particle screening at the inner wall and the top/bottom wall is larger than that at the outer limiter because of different magnetic topologies at different poloidal positions; and (2) although most of the particles (≥ 90%) impacting on the wall can be promptly re-emitted, a small fraction (≤ 10%) of them must be retained in the wall for a period of time which is similar to or larger than the global plasma particle confinement time. However, the wall particle retention time need not be different from that of the outer limiter, i.e. pumping can occur when there is no difference between the material properties of the limiter and those of the wall.

    Fluctuating wall pressures were measured using an array of 16 piezoelectric transducers beneath a turbulent boundary layer. The coating used in this experiment was an open cell, urethane type foam with a porosity of approximately 50 ppi. The ultimate objective of the coating is to provide a mechanical filter to reduce the wall pressure fluctuations. The ultimate objective of the coating is to provide a mechanical filter to reduce the wall pressure fluctuations. The boundary layer on the flat plate was measured by using a hot wire probe, and the CPM method was used to determine the skin friction coefficient. The wall pressure autospectra and streamwise wavenumber frequency spectra were compared to assess the attenuation of the wall pressure field by the coating. The coating is shown to attenuate the convective wall pressure energy. However, the relatively rough surface of the coating in this investigation resulted in a higher mean wall shear stress, thicker boundary layer, and higher low frequency wall pressure spectral levels compared to a smooth wall.

  13. Raman spectroscopic study of a post-medieval wall painting in need of conservation.

    Edwards, Howell G M; Farwell, Dennis W; Brooke, Christopher J

    2005-09-01

    Raman spectroscopic studies of four specimens from an important angel wall painting in need of conservation work in a medieval church have provided some information about the pigments and pigment compositions which will influence possible future preservation and restoration strategies. Excitation of the Raman spectra at 1,064 nm in macroscopic mode and at 785 nm in microscopic mode revealed that the white pigment on the angel's wings was a mixture of barytes with calcite and lead white in minor composition. Although the specimens provided were not directly associated with coloured regions of the painting, yellow and blue microcrystals were found and they were identified as chrome yellow and lazurite, respectively. Red and brown particles were identified as cinnabar/vermilion and haematite. Several green particles were also found but could not be identified. The green and blue crystals could be related to neighbouring coloured regions of the artwork and the yellow colour could be identified as a background to the angel figure. Particles of carbon were found to be dispersed throughout the specimens and can be ascribed to soot from candles, heating stoves or oil lamps providing lighting in the church. No evidence for biological deterioration was found from the spectra. The unusual pigment palette is strongly suggestive of a later date of painting than was originally believed but there is a possibility that an earlier rendition exists underneath. Following a review of the spectroscopic data, a more extensive sampling protocol is recommended, from which some stratigraphic evidence could identify the underlying plaster and possible artwork.

    A space between a pair of vertical steel plates laterally disposed in parallel at an optional distance has a structure of a plurality of vertically extending tranks partitioned laterally by vertically placed steel plates. Then, cements are grouted to the tranks. Strip-like steel plates each having a thickness greater than the gap between the each of the vertically placed steel plates and the cement are bonded each at the surface for each of the vertically placed steel plates opposing to the cements. A protrusion of a strip width having radiation shielding performance substantially identical with that by the thickness of the cement is disposed in the strip-like steel plates. With such a constitution, a safety radiation shielding wall structure with no worry of radiation intrusion to gaps, if formed, between the steel plates and the grouted cements due to shrinkage of the cements.

  15. Observations on resistive wall modes

    International Nuclear Information System (INIS)

    Gerwin, R.A.; Finn, J.M.

    1996-01-01

    Several results on resistive wall modes and their application to tokamaks are presented. First, it is observed that in the presence of collisional parallel dynamics there is an exact cancellation to lowest order of the dissipative and sound wave effects for an ideal Ohm's law. This is easily traced to the fact that the parallel dynamics occurs along the perturbed magnetic field lines for such electromagnetic modes. Such a cancellation does not occur in the resistive layer of a tearing-like mode. The relevance to models for resistive wall modes using an electrostatic Hammett-Perkins type operator to model Landau damping will be discussed. Second, we observe that with an ideal Ohm's law, resistive wall modes can be destabilized by rotation in that part of parameter space in which the ideal MHD modes are stable with the wall at infinity. This effect can easily be explained by interpreting the resistive wall instability in terms of mode coupling between the backward stable MHD mode and a stable mode locked into the wall. Such an effect can occur for very small rotation for tearing-resistive wall modes in which inertia dominates viscosity in the layer, but the mode is stabilized by further rotation. For modes for which viscosity dominates in the layer, rotation is purely stabilizing. For both tearing models, a somewhat higher rotation frequency gives stability essentially whenever the tearing mode is stable with a perfectly conducting wall. These tearing/resistive wall results axe also simply explained in terms of mode coupling. It has been shown that resonant external ideal modes can be stabilized in the presence of resistive wall and resistive plasma with rotation of order the nominal tearing mode growth rate. We show that these modes behave as resistive wall tearing modes in the sense above. This strengthens the suggestion that rotational stabilization of the external kink with a resistive wall is due to the presence of resistive layers, even for ideal modes

    2003-01-01

    Domain wall networks on the surface of a soliton are studied in a simple theory. It consists of two complex scalar fields, in 3+1 dimensions, with a global U(1)xZ n symmetry, where n>2. Solutions are computed numerically in which one of the fields forms a Q ball and the other field forms a network of domain walls localized on the surface of the Q ball. Examples are presented in which the domain walls lie along the edges of a spherical polyhedron, forming junctions at its vertices. It is explained why only a small restricted class of polyhedra can arise as domain wall networks

    1902-01-01

    For a number of years I have been gradually accumulating material for a thorough revision of the Tertiary floras of the Pacific slope. Fossil plants are known to occur at numerous points within this area, and their study and identification has already furnished valuable data bearing on the geological history of the region, and when still further exploited it is confidently expected that they will afford more exact data for the use of geologists. This investigation is progressing satisfactorily, and at no distant day it is hoped to have it in form for final publication. From time to time various members of the United States Geological Survey, as well as others not connected with this organization, have sent in small collections of fossil plants for determination. These have been studied and reported upon as fully as the condition of the problem permitted, so that the determinations could be immediately available to geologists, but with the reservation that none of the questions could be fully settled until all known material had been studied and properly correlated. The rich fossil plant deposits in the John Day Basin, as set forth more fully in the historical account which follows, have been known for a period of nearly fifty years, but their study has been carried on in a more or less desultory manner. There has also been considerable confusion as to the horizons whence these plants came. As various species of plants described originally from the John Day region were detected in various other localities in Oregon, and in surrounding areas, as central Washington, western Idaho, and northern California, it became more than ever apparent that a thorough study of all material obtainable from this type area would be necessary before any definite or satisfactory conclusions could be reached. The immediate incentive for this revision was furnished by the receipt of a considerable collection of plants, made by Dr. John C. Merriam in 1900 while he was in charge of an

    1999-02-01

    A descripion is given of the results of an environmental impact assessment of the construction of a natural gas pipeline that will bring gas from Maritimes and Northeast Pipeline Management Ltd.'s (M and NP) main transmission pipeline to clients in Lake Utopia and Saint John, NB. It will be 110 km long, and the Saint John lateral will join the mainline approximately 2 km south of Big Kedron Lake, NB. Various institutional, industrial, commercial and residential clients will be able to access the pipeline in the future, and it is intended to be capable of future expansion for markets along its route and for markets that become economically feasible in the future. A matrix was developed that relates environmental resources to Environmental Components of Concern (ECCs), and to the rationale for exclusion/inclusion of the ECC as a Valued Environmental Component (VECs). The positive benefits of the pipeline to clients in the Saint John area include: reduced dependence on foreign oil, fuel switching and price competition, lower air emission pollution, increased energy efficiency, and a source of energy that is secure and reliable. VECs were selected based on: concerns of various stakeholders including the public, community groups, scientific parties, Aboriginal groups, government officials and agencies, relevant regulations; relevant literature; and past evaluation experiences, including future developments of the proposed study area. Further selection of the VECs required an examination of the issues picked out via scoping to determine the ways in which the overall project could affect the ECCs, and included construction, operation, decommissioning/abandonment, malfunctions and accidents of the pipeline. The phases of the project as they impacted residually and cumulatively on the VECs were evaluated, and impacts on Valued Socio-Economic Components (VSCs) were assessed also. The mitigation efforts taken will minimize the potential effects of the project on VECs and VSCs

    2009-12-01

    Full Text Available The study of Cristina Campo’s translations offers a precious contribution to those of us who are attempting to investigate the unknown area that lies in the shadowy zone between the source text and its translation. Vittoria Guerrini, a rather solitary and reticent figure in 20th-century Italian literature, wrote under several pen names, of which her favourite was Cristina Campo, the masque she chose for her beautiful and intense translations of a small but significant collection of poems by John Donne. This paper aims at exploring Cristina Campo’s attitude towards translation and the unique relationship she established with the poets she translated. John Donne’s translations reflect a singular solidarity displaying points of affinity between two extremely complex personalities. The dialogic rapport abolishes difference in space and time, as well as difference in language, as author and translator testify the same supreme tension towards beauty, truth and perfection. Translation in this perspective is a sacred gesture of mediation.

    John Scott (1940-2013) was born in Dublin where he was to spend the rest of his career, both as an undergraduate and subsequently Professor of Biochemistry and Nutrition at Trinity College. His research with the talented group of scientists and clinicians that he led has had a substantial impact on our understanding of folate metabolism, mechanisms of its catabolism and deficiency. His research established the leading theory of folate involvement with vitamin B12 in the pathogenesis of vitamin B12 neuropathy. He helped to establish the normal daily intake of folate and the increased requirements needed either in food or as a supplement before and during pregnancy to prevent neural tube defects. He also suggested a dietary supplement of vitamin B12 before and during pregnancy to reduce the risk of neural tube defects. It would be an appropriate epitaph if fortification of food with folic acid became mandatory in the UK and Ireland, as it is in over 70 other countries. © 2013 John Wiley & Sons Ltd.

    2012-06-20

    The journey of exploration undertaken by Charles Darwin FRS during the voyage of HMS Beagle has a central place within the historical development of evolutionary theory and has been intensively studied. Despite this, new facts continue to emerge about some of the details of Darwin's activities. Drawing on recently published Darwin material and unpublished letters in the archives of the Royal Botanic Gardens, Kew, we document a hitherto unexamined link between Darwin and John Tweedie (1775-1862), a relatively obscure Scottish gardener turned South American plant collector. All of the available evidence points to a meeting between the two men in Buenos Aires in 1832. Tweedie provided Darwin with information about the geography of the Rio Paraná, including the locality of fossilized wood eroding from the river bank. It also seems likely that Tweedie supplied Darwin with seeds that he later shipped back to John Stevens Henslow in Cambridge. Although this brief meeting was at the time relatively unimportant to either man, echoes of that encounter have resonated with Tweedie's descendants to the present day and have formed the basis for a family story about a written correspondence between Darwin and Tweedie. Local information supplied to Darwin by residents such as Tweedie was clearly important and deserves further attention.

I conclude with a discussion of the theoretical difficulties he encountered in absorbing cultural, philosophical, political and religious Western pluralism in his theory.

    Full Text Available John Updike is widely considered to be one of the greatest, one of the most popular and sometimes most controversial writers concerned with the American small town and middle-class materialism. A lot of literary critics and researchers observe that Updike’s finest work came from his exploration of ordinary America and from his use of elegant prose, rich with metaphor, to portray the public and private feelings of Americans, their daily rounds of life. In addition, discussing Updike’s individual works a lot of literary critics and researchers have observed the writer’s attempts to re-write myth in “the mythical age”1 of the twentieth century. Naturally enough, as the return to myth is assumed to be a certain feature of the Modernist movement, half a century later since Updike’s famous novel Centaur was penned, it is indispensable to re-examine the writer’s fictional intentions in the usage of myth. More importantly, it is needful to determine whether we can see the mythic elements and realistic details as a continuum or as the contrasted opposites in his so called “historical chronicles”. Updike’s novels and stories are filled with mythological motifs and character archetypes. Thus, the study aims at revisiting John Updike’s creation considering mythological elements and archetypal images of his heroes alongside with heroic masculinity, war, terrorism and American perfectionism.

    Domain walls naturally arise whenever a symmetry is spontaneously broken. They interconnect regions with different realizations of the broken symmetry, promoting structure formation from cosmological length scales to the atomic level1,2. In ferroelectric and ferromagnetic materials, domain walls with unique functionalities emerge, holding great promise for nanoelectronics and spintronics applications3-5. These walls are usually of Ising, Bloch or Néel type and separate homogeneously ordered domains. Here we demonstrate that a wide variety of new domain walls occurs in the presence of spatially modulated domain states. Using magnetic force microscopy and micromagnetic simulations, we show three fundamental classes of domain walls to arise in the near-room-temperature helimagnet iron germanium. In contrast to conventional ferroics, the domain walls exhibit a well-defined inner structure, which—analogous to cholesteric liquid crystals—consists of topological disclination and dislocation defects. Similar to the magnetic skyrmions that form in the same material6,7, the domain walls can carry a finite topological charge, permitting an efficient coupling to spin currents and contributions to a topological Hall effect. Our study establishes a new family of magnetic nano-objects with non-trivial topology, opening the door to innovative device concepts based on helimagnetic domain walls.

  2. Anhydrobiosis in yeast: cell wall mannoproteins are important for yeast Saccharomyces cerevisiae resistance to dehydration.

    Borovikova, Diana; Teparić, Renata; Mrša, Vladimir; Rapoport, Alexander

    2016-08-01

    The state of anhydrobiosis is linked with the reversible delay of metabolism as a result of strong dehydration of cells, and is widely distributed in nature. A number of factors responsible for the maintenance of organisms' viability in these conditions have been revealed. This study was directed to understanding how changes in cell wall structure may influence the resistance of yeasts to dehydration-rehydration. Mutants lacking various cell wall mannoproteins were tested to address this issue. It was revealed that mutants lacking proteins belonging to two structurally and functionally unrelated groups (proteins non-covalently attached to the cell wall, and Pir proteins) possessed significantly lower cell resistance to dehydration-rehydration than the mother wild-type strain. At the same time, the absence of the GPI-anchored cell wall protein Ccw12 unexpectedly resulted in an increase of cell resistance to this treatment; this phenomenon is explained by the compensatory synthesis of chitin. The results clearly indicate that the cell wall structure/composition relates to parameters strongly influencing yeast viability during the processes of dehydration-rehydration, and that damage to cell wall proteins during yeast desiccation can be an important factor leading to cell death.

    The resistive effect of domain walls in FePd films with perpendicular anisotropy was studied experimentally as a function of field and temperature. The films were grown directly on MgO substrates, which induces an unusual virgin magnetic configuration composed of 60 nm wide parallel stripe domains. This allowed us to carry out the first measurements of the anisotropy of domain wall resistivity in the two configurations of current perpendicular and parallel to the walls. At 18 K, we find 8.2% and 1.3% for the domain wall magnetoresistance normalized to the wall width (8 nm) in these two respective configurations. These values are consistent with the predictions of Levy and Zhang.

Although there is no evident common line when comparing all types of hiska, the cunning eye may observe one shared feature: the positioning of the entrance. More or less all the documented shelters have south or south-western facing entrances. The burja is a cold northerly wind; from the south (Adriatic Sea the winds are warmer. When resting, the setting sun is taken as a sign of the ending of the working day and a reward for the whole day’s efforts. Entrances are the only openings to these structures, and they should serve as well as possible - to watch over the crops, to wait when hunting, to enjoy the calm of evening light, to breathe the sea wind.The syntax of the architectural language of layering stone and shaping the pattern of the landscape remain an inventive realisation of spatial ideas from the past until today. Not only ideas of shaping space - these ideas are basic interventions in the natural habitat which contribute to survival. Culture and an awareness of its values are the origins of local development and reasonable heritage preservation.

    The problem of impurities in fusion plasmas has been recognized since the beginning of the fusion programme. Early experiments in glass vacuum vessels released gas from the wall to such an extent that the radiation from the impurities prevented the plasma from being heated above about 50 eV. The radiative power loss is principally due to line radiation from partially stripped ions, which is particularly a problem during the plasma startup phase. Another problem is fuel dilution, which arises because impurity atoms produce many electrons and, for a given plasma pressure, these electrons take the place of fuel particles. Impurities can also lead to disruptions, as a result of edge cooling and consequent current profile modification. The fractional impurity level which radiates 10% of the total thermonuclear power for a 10 keV plasma is 50% for helium, 7% for carbon, and less than 0.1% for molybdenum. Clearly, impurities of low atomic number are a much less serious problem than those of high atomic number. (author)

  8. Water in St. John, U.S. Virgin Islands

    1972-01-01

    Water for domestic and municipal supply on St. John, in the past, has been obtained from rain catchments, dug wells, and barge shipments from St. Thomas and Puerto Rico. As a result of this study, small ground-water supplies have been developed for the Virgin Islands National Park. Ground water occurs in significant but limited quantities in the fractured volcanic rock throughout most of the Island. Yield of wells in this aquifer ranges from less than 100 to about 2,000 gpd (gallons per day). The average long-term yield of the three drilled wells in use by the National Park Service in 1967 was about 1,000 gpd. Yield ofl,000 to 5,000 gpd may be expected in the Coral Bay and the Reef Bay areas. Estimated total recharge of the fractured volcanic rock on St. John, based on a recharge of 1 to 3 inches per year, is 1,000,000 to 3,000,000 gpd. Perhaps as much as a quarter to a third of this water could be developed practically, depending on the rainfall in a given year. The chemical quality of the ground water in the fractured-rock aquifer in areas uncontaminated by sea water ranges from 600 to 2,000 mg/l (milligrams per liter) or more dissolved solids. Water from-formations in the higher altitudes is of better quality than that in the lower formations. Small quantities of ground water are available from beach sand, alluvium, and fractured rock near the sea. However, these sources tend to be brackish and are subject to salt-water encroachment. There are no perennial streams on St. John. There are a few spring-fed pools in stream channels, however, that are sustained, except in severe drought. Storm runoff is estimated to average 1 inch over the island annually, and evaporation from open water surfaces is about 70 inches per year. Ponds can be developed, but because of the high .evaporation they may be unreliable during droughts. Rain water collected in cisterns from roofs and catchments yield about 50 gpd per 1,000 square feet of catch area during an average year of

    The mean and phase averaged pressure and wall shear stress distributions were measured on the stator wall of a 50% eccentric annular seal which was whirling in a circular orbit at the same speed as the shaft rotation. The shear stresses were measured using flush mounted hot-film probes. Four different operating conditions were considered consisting of Reynolds numbers of 12,000 and 24,000 and Taylor numbers of 3,300 and 6,600. At each of the operating conditions the axial distribution (from Z/L = -0.2 to 1.2) of the mean pressure, shear stress magnitude, and shear stress direction on the stator wall were measured. Also measured were the phase averaged pressure and shear stress. These data were combined to calculate the force distributions along the seal length. Integration of the force distributions result in the net forces and moments generated by the pressure and shear stresses. The flow field inside the seal operating at a Reynolds number of 24,000 and a Taylor number of 6,600 has been measured using a 3-D laser Doppler anemometer system. Phase averaged wall pressure and wall shear stress are presented along with phase averaged mean velocity and turbulence kinetic energy distributions located 0.16c from the stator wall where c is the seal clearance. The relationships between the velocity, turbulence, wall pressure and wall shear stress are very complex and do not follow simple bulk flow predictions.

In detail, we want to study Milton’s prose works to extract the topics of the English civic and political tradition in the First Revolution age. In these terms, we’ll analyze the Commonplace Book, a collection of commentaries about texts and authors, and about various subjects: the interpretations of Machiavelli in the Old English tradition of the Modern age, the idea of man’s freedom and his relationship with natural law and political authority, according to the general perspective of the Puritan religion, which characterizes Milton’s political language.

    2004 was the centenary of John Ambrose Fleming's momentous patent on the thermionic diode that can be called the birth of electronics. The ''Edison effect'' was discovered in 1882; this was later shown to be the result of thermionic emission of electrons from a heated filament into a vacuum. Edison did not make any significant devices based on this discovery, and the effect was ignored for more than 8 years. In 1890 Fleming explained the effect and showed that the thermionic diode could be used as a rectifier. Fourteen years later Fleming filed his 1904 patent on the thermionic diode. It was the first public announcement of the electron tube; this revolutionized the development of radio and led to the invention of the thermionic triode by Lee de Forest in 1906. The background to these events will be described.

    The period around the publication of John Lubbock's Origin of civilisation in 1870 and Charles Darwin's Descent of man and selection in relation to sex the following year is key to a re-evaluation of the relationship between the two men, usually characterized as that of pupil and master. It is in the making of Descent that Lubbock's role as a scientific collaborator is most easily discerned, a role best understood within the social and political context of the time. Lubbock made Darwin—both the man and his science—acceptable and respectable. Less obvious is Darwin's conscious cultivation of Lubbock's patronage in both his private and public life, and Lubbock's equally conscious bestowal, culminating in his role in Darwin's burial in Westminster Abbey.

    Full Text Available John Locke, long associated with the “standard” approach to fallacies and the “logical” approach to valid inference, had both logical and dialectical reasons for favoring certain proofs and denigrating others. While the logical approach to argumentation stands forth in Locke’s philosophical writings (such as the Essay Concerning Human Understanding, a dialectical approach can be found in his contributions to public controversies regarding religion and toleration. Understanding Locke’s dialectical approach to argumentation not only makes his work more relevant to the contemporary discipline of informal logic, but this understanding also prompts a reconsideration of Locke’s rhetorical purpose. He approached argumentation dialectically (and logically because he wanted to appeal to a universal audience of free rational subjects, people not unlike the real historical audience whom Locke addressed: radical Whigs, latitudinarian Anglicans, early-Enlightenment philosophes.

    2016-01-01

    John Stewart Bell (1928-1990) was one of the most important figures in twentieth-century physics, famous for his work on the fundamental aspects of the century's most important theory, quantum mechanics. While the debate over quantum theory between the supremely famous physicists, Albert Einstein and Niels Bohr, appeared to have become sterile in the 1930s, Bell was able to revive it and to make crucial advances - Bell's Theorem or Bell's Inequalities. He was able to demonstrate a contradiction between quantum theory and essential elements of pre-quantum theory - locality and causality. The book gives a non-mathematical account of Bell's relatively impoverished upbringing in Belfast and his education. It describes his major contributions to quantum theory, but also his important work in the physics of accelerators, and nuclear and elementary particle physics.

    2011-05-01

    In 1844, before a large medical audience in London, John Hutchinson demonstrated the use of measurements of pulmonary function to predict disease. In contrast to standard practice at that time, he conducted an epidemiological investigation that would have been acceptable by today's standards, in which he examined over 2000 people and contrasted healthy and diseased cases. His data clearly indicated how, what he called, "vital capacity" predicted disease. Exploring the history of this young Victorian-era physician is both humbling and instructive for the modern epidemiologist, who has the advantages of the successes of ever more rapid, computer-based, technical approaches to evaluate existing data sources, and fewer opportunities to actually collect primary data from large number of patients using physiologic tools.

    2017-08-01

    Full Text Available The objective of this study is to investigate the conception of philosophy and its relation to human formation in the thinking of John Dewey. The work aimed at analyzing the concepts in the main works of the author and his interpreters. The paper analyzes the reconstruction of philosophy as a philosophy of experience anchored in the genetic, experimental, reflexive, critical and creative method. The philosophy of experience is opposed to the dualisms and the spectator philosophies of knowledge that maintains the social division into classes. The role of the philosophy of experience is to rationalize through inquiry the possibilities of human experience through the critical reconstruction of the meanings. The philosophy of experience is a condition of possibility for democratic life and for an education based on freedom and human emancipation.

    In June 1668 Anthony Ashley Cooper, later to become the 1st Earl of Shaftesbury, underwent abdominal surgery to drain a large abscess above his liver. The case is extraordinary, not simply on account of the eminence of the patient and the danger of the procedure, but also because of the many celebrated figures involved. A trove of manuscripts relating to this famous operation survives amongst the Shaftesbury Papers in the National Archives at Kew. These include case notes in the hand of the philosopher John Locke and advice from leading physicians of the day including Francis Glisson, Sir George Ent and Thomas Sydenham. The majority of this material has never been published before. This article provides complete transcriptions and translations of all of these manuscripts, thus providing for the first time a comprehensive case history.

    2007-05-22

    John Freind (1675/76-1728) achieved distinction in several walks of life, first as a classical scholar, then as a physician and as a chemist who advocated Newtonian philosophy. His clinical practice was generally conservative and he was against the newly introduced practice of inoculating the smallpox. His principles were Tory and High Church; his loyalty to the house of Stuart involved him in the Jacobite plot of 1722, and a spell in the Tower of London. His money was part of the foundation of Dr Lee's benefaction to Christ Church, which still survives in name in scientific posts in Oxford. He was among the circle of friends that Voltaire formed during his two-year stay in England and, 50 years later, Voltaire took him and his son as the principal characters in a conte philosophique defending a deistic attitude against both atheism and revealed religion.

  4. First wall of thermonuclear device

    International Nuclear Information System (INIS)

    Kizawa, Makoto; Koizumi, Makoto; Nishihara, Yoshihiro.

    1990-01-01

    The first wall of a thermonuclear device is constituted with inner wall tiles, e.g. made of graphite and metal substrates for fixing them. However, since the heat expansion coefficient is different between the metal substrates and intermediate metal members, thermal stresses are caused to deteriorate the endurance of the inner wall tiles. In view of the above, low melting metals are disposed at the portion of contact between the inner wall tiles and the metal substrates and, further, a heat pipe structure is incorporated into the metal substrates. Under the thermal load, for example, during operation of the thermonuclear device, the low melting metals at the portion of contact are melted into liquid metals to enhance the state of contact between the inner wall tiles and the metal substrate to reduce the heat resistance and improve the heat conductivity. Even if there is a difference in the heat expansion coefficient between the inner wall tiles and the metal substrates, neither sharing stresses not thermal stresses are caused. Further, since the heat pipe structure is incorporated into the metal substrates, the lateral unevenness of the temperature in the metal substrates can be eliminated. Thus, the durability of the inner wall tiles can be improved. (N.H.)

    This invention concerns shielding walls opposing to plasmas of a thermonuclear device and it is an object thereof to conduct reactor operation with no troubles even if a portion of shielding wall tiles should be damaged. That is, the shielding wall tiles are constituted as a dual layer structure in which the lower base tiles are connected by means of bolts to first walls. Further, the upper surface tiles are bolt-connected to the layer base tiles. In this structure, the plasma thermal loads are directly received by the surface layer tiles and heat is conducted by means of conduction and radiation to the underlying base tiles and the first walls. Even upon occurrence of destruction accidents to the surface layer tiles caused by incident heat or electromagnetic force upon elimination of plasmas, since the underlying base tiles remain as they are, the first walls constituted with stainless steels, etc. are not directly exposed to the plasmas. Accordingly, the integrity of the first walls having cooling channels can be maintained and sputtering intrusion of atoms of high atom number into the plasmas can be prevented. (I.S.)

  6. Decentred Centre in John Fowles’s The Magus

    Full Text Available Decentred Centre in John Fowles’sThe Magus Abstract John Fowles’ The Magus (1966 has been the focus of criticism for many years. This study regards the character of Conchis as a decentred “centre” in the structure of the novel and as in the experience of the contemporary humanity. Conchis becomes in the eyes of Nicholas an all-knowing figure, an accumulation of Western thought since the Greek civilization. He produces signs to be read as he himself becomes a body of various signs that construct him as the metaphysical centre that Western thinkers have relied upon. His narration becomes superior to Nicholas’ and he himself becomes only a narrative voice. The voice from the times of Plato has been considered as a direct expression of the thoughts in one’s mind and thus superior to writing that is permeated with the undecidability of meaning in the absence of the speaker and the addressee. In the novel, words as an endless play of metaphors take the place of voice. There is no knowable reality outside the play words or metaphors which is an endless chain of signifiers that lead to other signifiers. Every time Nicholas turns to Conchis to find the centre outside the play of the language, he finds other signifiers. Thus, Conchis as a meaning-making centre is dethroned. He is not the sole operator of the masks that divert from their presumed original target when they are read. Nicholas is just another production of the literary tradition who reads the signs only to produce other signs. Conchis in the beginning of the novel renounces fiction for science but along the course of the novel, we see that words are never reliable whether in fiction or in science.

  7. A computational approach for inferring the cell wall properties that govern guard cell dynamics.

    Guard cells dynamically adjust their shape in order to regulate photosynthetic gas exchange, respiration rates and defend against pathogen entry. Cell shape changes are determined by the interplay of cell wall material properties and turgor pressure. To investigate this relationship between turgor pressure, cell wall properties and cell shape, we focused on kidney-shaped stomata and developed a biomechanical model of a guard cell pair. Treating the cell wall as a composite of the pectin-rich cell wall matrix embedded with cellulose microfibrils, we show that strong, circumferentially oriented fibres are critical for opening. We find that the opening dynamics are dictated by the mechanical stress response of the cell wall matrix, and as the turgor rises, the pectinaceous matrix stiffens. We validate these predictions with stomatal opening experiments in selected Arabidopsis cell wall mutants. Thus, using a computational framework that combines a 3D biomechanical model with parameter optimization, we demonstrate how to exploit subtle shape changes to infer cell wall material properties. Our findings reveal that proper stomatal dynamics are built on two key properties of the cell wall, namely anisotropy in the form of hoop reinforcement and strain stiffening. © 2017 The Authors The Plant Journal © 2017 John Wiley & Sons Ltd and Society for Experimental Biology.

    Numerous studies in applied pedagogical design have shown that, at all educational levels, direct exposure to the natural environment can enhance learning by improving student attention and behaviors. Implementing green walls-a "vertical garden," or "living wall" interior wall that typically includes greenery, a growing medium (soil or substrate) and a water delivery system-provides environmental health benefits, but also provides a practical application within classrooms for minimizing directed attention fatigue in students by connecting them to "outdoor nature" within the indoor environment. Hands-on "project-based" learning is another pedagogical strategy that has proved to be effective across the spectrum of educational levels and across subject areas. Green walls have the potential to inspire critical thinking through a combination of project-based learning strategies and environmental education. The authors have outlined a curriculum involving the implementation of an indoor living wall system within a classroom-learning environment, incorporating project-based learning modules that interact with the wall. In conjunction with the passive health benefits of a green wall, project-based curriculum models can connect students interactively with indoor nature and have the potential to inspire real-world thinking related to science, technology, engineering, art, and mathematics fields within the indoor learning environment. Through a combination of these passive and interactive modes, students are connected to nature in the indoor environment regardless of weather conditions outdoors. Future research direction could include post-construction studies of the effectiveness of project-based curricula related to living walls, and the long-term impacts of implementing green walls in classrooms on school achievement and student behaviors.

    2013-10-01

    The economic aspects of abdominal wall reconstruction are frequently overlooked, although understandings of the financial implications are essential in providing cost-efficient health care. Ventral hernia repairs are frequently performed surgical procedures with significant economic ramifications for employers, insurers, providers, and patients because of the volume of procedures, complication rates, the significant rate of recurrence, and escalating costs. Because biological mesh materials add significant expense to the costs of treating complex abdominal wall hernias, the role of such costly materials needs to be better defined to ensure the most cost-efficient and effective treatments for ventral abdominal wall hernias.

    Double-walled steam generator tubing for the steam generators of a liquid metal cooled fast breeder reactor prevents sliding between the surfaces due to a mechanical interlock. Forces resulting from differential thermal expansion between the outer tube and the inner tube are insufficient in magnitude to cause shearing of base metal. The interlock is formed by jointly drawing the tubing, with the inside wall of the outer tube being already formed with grooves. The drawing causes the outer wall of the inner tube to form corrugations locking with the grooves. (author)

  4. Gravity and domain wall problem

    International Nuclear Information System (INIS)

    Rai, B.; Senjanovic, G.

    1992-11-01

    It is well known that the spontaneous breaking of discrete symmetries may lead to conflict with big-bang cosmology. This is due to formation of domain walls which give unacceptable contribution to the energy density of the universe. On the other hand, it is expected that gravity breaks global symmetries explicitly. In this work we propose that this could provide a natural solution to the domain-wall problem. (author). 17 refs

    A pump system includes a particulate consolidator pump that has a pump outlet. A duct is coupled to the pump outlet. The duct has a wall that is coupled with an oscillator. The oscillator is operable to oscillate the wall at a controlled frequency. The controlled frequency is selected with respect to breaking static bridging of particulate in the duct due, at least in part, to consolidation of the particulate from a downstream check valve.

  6. Dressed Domain Walls and holography

    International Nuclear Information System (INIS)

    Grisa, Luca; Pujolas, Oriol

    2008-01-01

    The cutoff version of the AdS/CFT correspondence states that the Randall Sundrum scenario is dual to a Conformal Field Theory (CFT) coupled to gravity in four dimensions. The gravitational field produced by relativistic Domain Walls can be exactly solved in both sides of the correspondence, and thus provides one further check of it. We show in the two sides that for the most symmetric case, the wall motion does not lead to particle production of the CFT fields. Still, there are nontrivial effects. Due to the trace anomaly, the CFT effectively renormalizes the Domain Wall tension. On the five dimensional side, the wall is a codimension 2 brane localized on the Randall-Sundrum brane, which pulls the wall in a uniform acceleration. This is perceived from the brane as a Domain Wall with a tension slightly larger than its bare value. In both cases, the deviation from General Relativity appears at nonlinear level in the source, and the leading corrections match to the numerical factors.

  8. John Leland’s Caer Urfe: Tynemouth or Chepstow?

    Directory of Open Access Journals (Sweden)

    Andrew Breeze

    2017-03-01

    Full Text Available The paper focuses on the problem of identification of Caer Urfe, one of the Twenty-Eight Cities of Britain listed by John Leland (d. 1552 from Henry of Huntingdon (d. 1155 after the ninth-century Historia Brittonum. Many of the twenty-eight have defied identification; but Leland’s proposal of Tynemouth for Caer Urfe is now maintained by archaeologists on Tyneside, in the north of England. The author argues that Caer Urfe is to be associated with St Cynfarch, near Chepstow, in south-east Wales. It is one of ten Welsh religious communities named in the catalogue together with cathedral cities and ancient British hillforts, none of them on Tyneside. The paper also examines the case of Arbeia, recorded by Notitia Dignitatum as the name of the Roman fort at South Shields, Tyneside. The author shows that Arbeia has no link with Caer Urfe, nor does it mean ‘Arabs,’ supposedly relating to the garrisoning there after 300 CE of troops from Iraq. Many Roman forts in Britain were called after streams close to them; Arbeia is hence best understood on the basis of Welsh erfin ‘turnips,’ also the name of a stream near Aberystwyth, as ‘ stream noted for wild turnips’. The article is supplemented with an appendix containing a list of the twenty-eight cities from Leland’s catalogue, with toponyms rectified after the twelfth-century Book of Llandaff and other Welsh documents.

  9. Fab Four: When John and George Play Gravitation and Cosmology

    Directory of Open Access Journals (Sweden)

    2012-01-01

    Full Text Available Scalar-tensor theories of gravitation attract again a great interest since the discovery of the Chameleon mechanism and of the Galileon models. The former allows reconciling the presence of a scalar field with the constraints from Solar System experiments. The latter leads to inflationary models that do not need ad hoc potentials. Further generalizations lead to a tensor-scalar theory, dubbed the “Fab Four,” with only first and second order derivatives of the fields in the equations of motion that self-tune to a vanishing cosmological constant. This model needs to be confronted with experimental data in order to constrain its large parameter space. We present some results regarding a subset of this theory named “John,” which corresponds to a nonminimal derivative coupling between the scalar field and the Einstein tensor in the action. We show that this coupling gives rise to an inflationary model with very unnatural initial conditions. Thus, we include the term named “George,” namely, a nonminimal, but nonderivative, coupling between the scalar field and Ricci scalar. We find a more natural inflationary model, and, by performing a post-Newtonian analysis, we derive the set of equations that constrain the parameter space with data from experiments in the Solar System.

  10. John Woolman and Ethical Progress in Kitcher's Pragmatic Naturalism.

    Science.gov (United States)

    Barresi, John

    2017-01-01

    The development of John Woolman’s views on slavery plays an important evidentiary role in Philip Kitcher’s recent book, The ethical project (Kitcher 2011). In this work Kitcher takes what he calls a “pragmatic naturalist” approach to ethics and claims that the discovery of ethical truth plays no role in the emergence of ethical progress. To support his view, he argues that Woolman’s contribution was not due to his discovery of an ethical truth about slavery, not previously known, but due to his sensitivity to slavery and his influence on others, which contributed to collective progressive change in moral norms involving slavery. While not disputing Kitcher’s ethical theory, I argue that personal discoveries of a moral psychological nature made by Woolman served both as insights and motivations for his contribution. Thus, even if there are no such things as independent ethical truths that can be discovered by individuals, a fully naturalistic approach to ethical progress requires that we make room not only for group-level progressive evolution of norms, but also for individual discoveries of a moral psychological nature that can sometimes cause an individual to play a significant initiating role in progressive ethical transitions that occur at a group level.

  11. John Cage's Aria viewed through the prism of contextual determination

    2017-01-01

    Full Text Available The paper analysis the three contextual layers of creating John Cage's Aria for solo voice performed by Cathy Berberia at the 'big stage' of musical neo-avant-garde in Darmstadt. The layers in question are: (1 the socio-political context of Germany after World War II, where the denazification process was started at the time, (2 the artistic context of neo-avant-garde musical milieu which was being formed in Darmstadt in that period, and (3 the context of a new epoch in the history of vocal art. The thesis presented here is that an encounter occurred between American experimental and European avant-garde musical practice during the accelerated denazification and liberalisation of German society and the establishment of the Cold War relationship between the East and the West. The piece Aria represents an example of a collaborative work between American and European artists, which turned to be an important step in the history of extended vocal techniques in musical performing and composing.

  12. John Stuart Mill, innate differences, and the regulation of reproduction.

    Science.gov (United States)

    Paul, Diane B; Day, Benjamin

    2008-06-01

    In this paper, we show that the question of the relative importance of innate characteristics and institutional arrangements in explaining human difference was vehemently contested in Britain during the first half of the nineteenth century. Thus Sir Francis Galton's work of the 1860s should be seen as an intervention in a pre-existing controversy. The central figure in these earlier debates-as well as many later ones-was the philosopher and economist John Stuart Mill. In Mill's view, human nature was fundamentally shaped by history and culture, factors that accounted for most mental and behavioral differences between men and women and among people of different classes, nationalities, and races. Indeed, Mill's whole program of social reform depended on the assumption that human differences were not fixed by nature. To identify the leading figures in these disputes about difference and the concrete context in which they occurred, we explore three debates in which Mill played a key role: over the capacities and rights of women, the viability of peasant proprietorship in India and Ireland, and the status of black labor in Jamaica. The last two draw our attention to the important colonial context of the nature-nurture debate. We also show that ideas that for us seem of a piece were not always linked for these earlier thinkers, nor did views on innateness necessarily have the political correlates that we now take for granted.

  13. John Zorn: Autonomy and the Avant-Garde (excerpt

    Directory of Open Access Journals (Sweden)

    Ted Gordon

    2012-06-01

    Full Text Available This essay is an excerpt for a larger paper exploring the concept of autonomy as it emerges in the life and work of the composer, performer, record label executive and club-owner John Zorn. Zorn’s activities over his wide-ranging career span from performing at jazz lofts in the 1970s to winning the MacArthur “genius” grant in 2008, while maintaining his status as a prolific composer and producer of avant-garde music. In interviews, documentaries, and in his music, Zorn often comments on his status as an avant-garde producer, specifically within the context of the record industry and within New York City’s so-called “Downtown” scene. Economics take the forefront in determining artistic attitudes towards both production of music and the music itself, as Zorn has, seemingly, been forced by the “mainstream market” to create a parallel, vertically-integrated economic system to support the livelihood of himself and his collaborators. This excerpt, from the first third of the essay, unpacks Zorn’s relationship with Downtown scene, his conception of the avant-garde, and his attitude towards artists who have set precedents for Zorn’s version of autonomous cultural production. It also notes the idiosyncratic way that both Zorn and his critics have placed Zorn’s music both within and without two distinct traditions: Avant-Garde composition and free Jazz.

  14. The neurological legacy of John Russell Reynolds (1828-1896).

    Science.gov (United States)

    Eadie, M J

    2007-04-01

    Sir John Russell Reynolds was an eminent and highly influential physician in the Victorian era who held the Presidencies of the Royal College of Physicians of London, and of the British Medical Association. He was the protégée of the great experimental physiologist, Marshall Hall, who discovered the reflex arc, and succeeded to Hall's clinical practice in London. Reynolds' thought and clinical activities linked the emerging British neurology of the first half of the 19th century with its blossoming, particularly in London, from 1860 onwards. In his writings Reynolds was the first English author to apply the approach to classification of neurological disorders that is still often used, though now in modified form. He was also the first to enunciate the notion of positive and negative symptoms arising from neurological disease and to suggest their pathogenesis, and was arguably the originator of the influential concept that an idiopathic disease, epilepsy, existed, one to be distinguished from 'epileptiform' seizures due to brain pathology.

  15. Economic and social ethics in the work of John Calvin

    Directory of Open Access Journals (Sweden)

    Matthias Freudenberg

    2009-11-01

    Full Text Available John Calvin and Reformed Protestantism interlinked questions of life and death with questions of faith. Not only faith and the church, but life in general call for constant renewal through the word of God. These processes of renewal incorporate society and the economy. In contrast to the popular assertion that Calvin and Calvinism are responsible for capitalism and its aberrations, Calvin in particular shows a deep sensibility for human beings trapped in economic deprivation. In his sermons Calvin exhorts the rich to consider the poor as ‘their’ poor and to thank God by practicing generosity. This appreciation of social questions within an ecumenical context is demonstrated in the Reformed church in a whole array of charitable services. It will be crucial for the current debate on economic ethics to assess economic processes in relation to how they serve life. For it is liberty, justice and fellowship – as gifts of God – that serve as an orientation and an obligation to be aware of human beings suffering from the negative consequences of globalisation.

  16. The Poet as Translator: The Poetic Vision of John Betjeman

    Directory of Open Access Journals (Sweden)

    Wisam Khalid Abdul Jabbar

    2013-12-01

    Full Text Available Rainer Maria Rilke (1989 describes the quest of the poet as that of saying the “unsayable.” Similarly, poets like Ezra Pound and Octavio Paz suggest that when the poetic essence is beyond the words, then the poem enters the realm of the “untranslatable” and invites an act of translation. John Betjeman recognizes the complexity that is inherent to the heritage of the Modernist School which renders poetry to be as incomprehensible as any foreign language. This paper argues that Betjeman diverts from the stylistic density of the Modernist tradition because he discerns a similar unintelligibility in a receding English culture. Hence, translation becomes not only a vocation but an inevitability that looms large considering the social and political upheavals he witnessed. Drawing on Rilke and Paz’s understanding of the act of translation as seeking meaning “beyond the words per se” (Jackson, 2011, this paper explores Betjeman’s attempts to translate a condition which is both “unsayable” and foreign, which afflicted Englishness as a cultural locus.

    2013-01-01

    John William Polidori (1795-1821) was the Edinburgh-trained physician hired by Lord Byron to accompany him to Switzerland, where he participated in the story-telling event proposed by Byron that led, with Polidori's help, to Mary Shelley's Frankenstein. Although those interested in English literature might also remember Polidori as the author of The Vampyre, one of the first extended works of fiction about vampires, his earlier interest in somnambulism and trance states is only beginning to be appreciated. Even more than students of Romantic literature, historians of science and medicine seem little aware of what Polidori had written about oneirodynia, a synonym for somnambulism, and how his thoughts from 1815 about such activities reflected the changing medical zeitgeist at this time. This chapter examines Polidori's medical thesis in a neuroscience context and compares what he wrote to the writings of several other physicians who were fascinated by nocturnal wanderings, their causes, their manifestations, and their possible treatments. © 2013 Elsevier B.V.

    Directory of Open Access Journals (Sweden)

    2017-06-01

    Full Text Available 'Stoner' (1965, John Williams’s third novel, questions and complicates mythologised versions of modern American identity and way of life. The story moves through two World Wars, the Great Depression following the Wall Street crash, and President Franklin D. Roosevelt’s New-Deal America, a prolonged time of social upheaval throughout the world. The book re-imagines stuff-of-dreams versions of the American cultural hero modelled on the image of the brash, risk-taking and economically-successful individual of the 1920s decade. The position mediated by the narrative is one of disillusionment with a nation more in step with passionate, impulsive actions associated with cultural heroism than with cool, astute consideration of possible destructive consequences. Confronted and brought into question is the presumption of silence as ineffectual resistance to the injustices that operate within public and private institutionalized power structures. At first glance, Williams’s eponymous hero, William Stoner’s, wont to quietly internalize, rather than loudly agitate against, conflict-driven social environments, appears to reaffirm this view. Portrayed as a decent man who thinks before he speaks, Stoner’s character proffers the idea that silence and care-full thought before acting can be constructive in the pursuit of a better, more balanced way of being in the world. This essay argues that Stoner’s habitual interiority functions as a political symbolic filter to challenge commonly-held impressions of heroism understood as a garrulous, action-based cultural code of behavior in the practice of everyday life.

    Configurations of vortex strings stretched between or ending on domain walls were previously found to be 1/4 Bogomol'nyi-Prasad-Sommerfield (BPS) states in N=2 supersymmetric gauge theories in 3+1 dimensions. Among zero modes of string positions, the center of mass of strings in each region between two adjacent domain walls is shown to be non-normalizable whereas the rests are normalizable. We study dynamics of vortex strings stretched between separated domain walls by using two methods, the moduli space (geodesic) approximation of full 1/4 BPS states and the charged particle approximation for string end points in the wall effective action. In the first method we explicitly obtain the effective Lagrangian in the strong coupling limit, which is written in terms of hypergeometric functions, and find the 90 deg. scattering for head-on collision. In the second method the domain wall effective action is assumed to be U(1) N gauge theory, and we find a good agreement between two methods for well-separated strings.

  1. Isolation of the Cell Wall.

    Canut, Hervé; Albenne, Cécile; Jamet, Elisabeth

    2017-01-01

    This chapter describes a method allowing the purification of the cell wall for studying both polysaccharides and proteins. The plant primary cell wall is mainly composed of polysaccharides (90-95 % in mass) and of proteins (5-10 %). At the end of growth, specialized cells may synthesize a lignified secondary wall composed of polysaccharides (about 65 %) and lignin (about 35 %). Due to its composition, the cell wall is the cellular compartment having the highest density and this property is used for its purification. It plays critical roles during plant development and in response to environmental constraints. It is largely used in the food and textile industries as well as for the production of bioenergy. All these characteristics and uses explain why its study as a true cell compartment is of high interest. The proposed method of purification can be used for large amount of material but can also be downscaled to 500 mg of fresh material. Tools for checking the quality of the cell wall preparation, such as protein analysis and microscopy observation, are also provided.

  2. Modeling of shear wall buildings

    Many nuclear power plant buildings, for example, the auxiliary building, have reinforced concrete shear walls as the primary lateral load resisting system. Typically, these walls have low height to length ratio, often less than unity. Such walls exhibit marked shear lag phenomenon which would affect their bending stiffness and the overall stress distribution in the building. The deformation and the stress distribution in walls have been studied which is applicable to both the short and the tall buildings. The behavior of the wall is divided into two parts: the symmetric flange action and the antisymmetry web action. The latter has two parts: the web shear and the web bending. Appropriate stiffness equations have been derived for all the three actions. These actions can be synthesized to solve any nonlinear cross-section. Two specific problems, that of lateral and torsional loadings of a rectangular box, have been studied. It is found that in short buildings shear lag plays a very important role. Any beam type formulation which either ignores shear lag or includes it in an idealized form is likely to lead to erroneous results. On the other hand a rigidity type approach with some modifications to the standard procedures would yield nearly accurate answers.

    The John Adam Fleming Medal is awarded for "original research and technical leadership in geomagnetism, atmospheric electricity, aeronomy, space physics, and related sciences." Originality and technical leadership are exactly the characteristics that distinguish the research of Spiro K. Antiochos. Spiro possesses a truly unique combination of physical insight, creativity, and mastery of the concepts and mathematical and numerical tools of space physics. These talents have allowed him to develop completely original theories for major observational problems and to test and refine those theories using sophisticated numerical simulation codes that he himself helped to develop. Spiro's physical insight is especially impressive. He has an uncanny ability to identify the fundamental aspects of complex problems and to see physical connections where others do not. This can sometimes involve ideas that may initially seem counterintuitive to those with less creativity. Many of Spiro's revolutionary advances have opened up whole new areas of study and shaped the course of space physics. Examples include the breakout model for coronal mass ejections (CMEs), the S-web model for the slow solar wind, and the thermal nonequilibrium model for solar prominences. The breakout model is of special significance to AGU as it strives to promote science for the betterment of humanity. CMEs are enormous explosions on the Sun that can have major "space weather" impacts here on Earth. They affect technologies ranging from communication and navigation systems to electrical power grids. Breakout is the leading theory for why CMEs occur and may one day be the foundation for more accurate space weather forecasting.

  4. AIDS: just the facts from specialists at Johns Hopkins.

    1985-12-01

    This article, based on information from specialists at Johns Hopkins, poses and then answers 3 broad questions about the acquired immunodeficiency syndrome (AIDS). 1st, it is asked, "What is AIDS and how serious is it?" It is noted that AIDS is only 1 of several forms taken by infection with the human T-lymphotropic virus type III/lymphadenopathy-associated virus (HTLV-III/LAV). The earliest form of infection is believed to occur within a few weeks of exposure to the virus, and some patients develop an acute syndrome that resembles infectious mononucleosis. These symptoms disappear after 4-6 weeks, by which time the patient has developed antibodies to the virus. About 2-4%/year of asymptomatic carriers go on to develop AIDS-related complex (ARC), and 15-30% of ARC patients develop AIDS within 5 years. The 2nd question posed is, "How do you catch AIDS?" To cause infection, the virus must go directly into the blood, although the virus alone may not be enough to cause sickness. Previous viral infections such as hepatitis B, herpes, cytomegalovirus, and intestinal parasites have been suggested as co-factors of AIDS. Promiscuity increases the chances of contracting AIDS. Observations of the families of AIDS patients and health care personnel who work with AIDS patients suggest that AIDS cannot be caught by casual contact. Finally, it is asked, "What is being done about AIDS?" 4 strategies are outlined: 1) as a result of donor screening for antibodies to HTLV-III/LAV, AIDS has been completely removed from the blood banks; 2) virologists are attempting to understand the virus so that it can be attacked, and understanding has been advanced by the theory that HTLV-III might be what is called a "slow virus;" 3) education about AIDS is changing the sexual practices that transmit AIDS; and 4) epidemiologists are carefully following those who are at risk, have been exposed, or are already sick.

  5. Mathematics and Humor: John Allen Paulos and the Numeracy Crusade

    2015-07-01

    Full Text Available John Allen Paulos at minimum gave the Numeracy movement a name through his book Innumeracy: Mathematical Illiteracy and Its Consequences. What may not be so obvious was Paulos’ strong interest in the relationship between mathematics and mathematicians on the one hand and humor and stand-up-comedian joke structures on the other. Innumeracy itself could be seen as a typically mathematical Gotcha joke on American culture generally. In this perspective, a Minnesotan acculturated to Minnesota-Nice Humor of Self-Immolation Proclivities (SImP looks at the more raw-boned, take-no-prisoners humor style Paulos outlined in Mathematics and Humor and implemented in Innumeracy. Despite the difference in humor styles, there is much to applaud in Paulos’ analysis of the relationship between certain types of humor and professional interests of mathematicians in Mathematics and Humor. Much humor relies on the sense of incongruity which Paulos’ claims to be central to all humor and key to mathematical reductio ad absurdum. Mathematics is rightfully famous for a sense of combinatorial playfulness in its most elegant proofs, as humor often relies on clashing combinations of word play. And a great range of mathematical lore is best understood within a concept of a sudden drop from one sense of certainty to another (essentially a Gotcha on the audience. Innumeracy repeatedly exemplifies Gotchas on the great unwashed and unmathematical majority. Extensive empirical evidence over the last quarter century allows us to synthesize these Paulos observations into the idea that inculcated mathematical humor has strong propensities to complex Intellectual, Advocate, and Crusader humor forms. However, the Paulos humors do not include the Sympathetic Pain humor form, the inclusion of which may increase teaching effectiveness.

  6. Pope John Paul II apologizes for church's oppression of women.

    Science.gov (United States)

    1995-01-01

    In a 16-page letter which is widely viewed by women's groups as an effort to win support for the Vatican's position at the upcoming UN Conference on Women in Beijing, Pope John Paul II apologizes to women throughout the world for the church's historic complicity in their oppression. Although phrased in general terms, the letter contains language and ideas of a far more feminist tone than any previous statements or declarations made by the Pontiff. Calling for increased respect for women and sensitivity to their needs, the letter also claims that "there is an urgent need to achieve real equality in every area: equal pay for equal work, protection for working mothers, fairness in career advancements, equality of spouses with regard to family rights and recognition of everything that is part of the rights and duties of citizens in a democratic state." Recognizing women's significant achievements and sacrifices inside and outside of the home, the Pope expressed admiration for "those women of good will who have devoted their lives to defending the dignity of womanhood by fighting for their basic social, economic and political rights, demonstrating courageous initiative at a time when this was considered extremely inappropriate, the sign of a lack of femininity, a manifestation of exhibitionism, and even a sin." Although the letter heralds a new awareness in the Vatican of women's views, concerns and grievances, the Pope has not signaled any dramatic changes in official church policy: women's ordination, divorce, abortion and birth control are still considered beyond the pale of acceptability. full text

    Full Text Available This paper examined the epistemological empiricism conception of Ibn Taimiyyah and John Locke based on the comparative analysis to obtain the complete description of epistemological empiricism thought of both, as well as its implications and consequences for the development of science and religious thought. To obtain the detailed answer about the two figures thought, it would be revealed the similarities and differences of epistemological empiricism of each by showing the elements that became the focus of both studies. Furthermore, from those, it will be sought the strange and weaknesses, and possible relevance of the two thought to find a new alternative as a reflective systematic model for the development of science and religious thought in the present and future. Comparing the empirical thought of both figures above is important to do, due to the empirical tradition in the two mens’ world have a very extreme differences. In the west, Empiricism had contributed significantly to the epistemological assets or legacy and had led to the development of science and technology. In contrast, empiricism in the east, was suspected as a harmful tradition to the Islamic ideology. It was considered as the seed that gave birth to atheism. Based on the two thinkers empiricism, will appear the strategic idea that can be synthesized to developed modern science as well as Islamic thought. Bot of epistemology thought can be combine to reconstruct the Islamic epistemology which is more open and more mature, because in that context will emerge the theories of knowledge without eliminating the metaphysical and ethical authority. In the context of combination, the natural tendency of foundation of Islamic teaching should be the bases of policy as descript by Ibnu Taimiyyah, that human nature becomes the foundation of the human responsibility in the end after and imposition of responsibility or duty, are the necessities to obey Allah order and to leave the Allah

    Grasses represent an abundant and widespread source of lignocellulosic biomass, which has yet to fulfil its potential as a feedstock for biorefining into renewable and sustainable biofuels and commodity chemicals. The inherent recalcitrance of lignocellulosic materials to deconstruction is the most crucial limitation for the commercial viability and economic feasibility of biomass biorefining. Over the last decade, the targeted genetic engineering of grasses has become more proficient, enabling rational approaches to modify lignocellulose with the aim of making it more amenable to bioconversion. In this review, we provide an overview of transgenic strategies and targets to tailor grass cell wall polysaccharides for biorefining applications. The bioengineering efforts and opportunities summarized here rely primarily on (A) reprogramming gene regulatory networks responsible for the biosynthesis of lignocellulose, (B) remodelling the chemical structure and substitution patterns of cell wall polysaccharides and (C) expressing lignocellulose degrading and/or modifying enzymes in planta. It is anticipated that outputs from the rational engineering of grass cell wall polysaccharides by such strategies could help in realizing an economically sustainable, grass-derived lignocellulose processing industry. © 2017 The Authors.

  13. Chest Wall tumor: combined management

    Cancer is relatively rare disease among children and adolescents. The incidence of solid tumors other than CNS is less than 2/100,000. Tumors of the chest wall can arise either from the somatic tissue or ribs. These are rare, so either institutional reviews or multi institutional studies should determine optimal therapeutic management. Of the bony chest wall, Ewing's sarcoma or the family of tumor (peripheral neuro epithelioma, Askin tumor), are the most common. These lesions are lytic and have associated large extra pleural component. This large extra pleural component often necessitates major chest wall resection (3 or more ribs), and when lower ribs are involved, this entails resection of portion of diaphragm. Despite this resection, survival in the early 1970 was 10-20%. Since 1970 multi agent chemotherapy has increased survival rates. of importance, however, is these regimens have caused significant reduction of these extra pleural components so that major chest wall resections have become a rarity. With improved survival and decreased morbidity preoperative chemotherapy followed by surgery is now the accepted modality of treatment. Another major advantage of this regimen is that potential radiation therapy may be obviated. The most common chest wall lesion is rhabdomyosarcoma. In the IRS study of 1620 RMS patients, in 141 (9%) the primary lesion was in the chest wall. these are primarily alveolar histology. when lesions were superficial, wide local excision with supplemental radiation therapy was associated with low morbidity and good overall survival. however, a majority have significant intra- thoracic components. in these circumstances the resectability rate is less than 30% and the survival poor. Other lesions include non rhabdomyosarcomas, eosinophilic granuloma, chondrosarcoma, and osteomyelitis. The management of these lesions varies according to extent, histology, and patient characteristics

    2017-01-01

    The effect of subclinical paratuberculosis (or Johne's disease) risk status on performance, health, and fertility was studied in 58,096 UK Holstein-Friesian cows with 156,837 lactations across lactations 1 to 3. Low-, medium-, and high-risk group categories were allocated to cows determined by a minimum of 4 ELISA milk tests taken at any time during their lactating life. Lactation curves of daily milk, protein, and fat yields and protein and fat percentage, together with log e -transformed somatic cell count, were estimated using a random regression model to quantify differences between risk groups. The effect of subclinical paratuberculosis risk groups on fertility, lactation-average somatic cell count, and mastitis were analyzed using linear regression fitting risk group as a fixed effect. Milk yield losses associated with high-risk cows compared with low-risk cows in lactations 1, 2, and 3 for mean daily yield were 0.34, 1.05, and 1.61kg; likewise, accumulated 305-d yields were 103, 316, and 485kg, respectively. The total loss was 904kg over the first 3 lactations. Protein and fat yield losses associated with high-risk cows were significant, but primarily a feature of decreasing milk yield. Similar trends were observed for both test-day and lactation-average somatic cell count measures with higher somatic cell counts from medium- and high-risk cows compared with low-risk cows, and differences were in almost all cases significant. Likewise, mastitis incidence was significantly higher in high-risk cows compared with low-risk cows in lactations 2 and 3. Whereas the few significant differences between risk groups among fertility traits were inconsistent with no clear trend. These results are expected to be conservative, as some animals that were considered negative may become positive after the timeframe of this study, particularly if the animal was tested when relatively young. However, the magnitude of milk yield losses together with higher somatic cell counts and

    John Peters and his committee had a few basic goals. One was that local, state, and federal governments needed to provide money to construct facilities, support medical research and education, and care for the poor. And they wanted experts to call the shots. Over time, Peters and the committee got what they wanted for the most part: Hill-Burton money for building the hospitals, the rise of the National Institutes of Health, Medicare, Medicaid, a Veterans Administration system, and new and expanded medical schools. The experts calling the shots included David Kessler at the Food and Drug Administration and Surgeon General C. Everett Koop. In the halcyon days of American health system reform, back in 1993, Yale's Paul Beeson wrote about the Committee of 430 Physicians and its goals in the Pharos of Alpha Omega Alpha. Beeson was optimistic and he quoted from my 1991 JAMA health system reform editorial as a sharp contrast to what Fishbein had written - although coincidentally, we both quote Lincoln. My editorial began, "'with malice toward none, with charity for all...' so spoke Abraham Lincoln in his second inaugural address recognizing that he had no political consensus regarding either the constitutionality of states seceding or the morality of slavery being abolished. Nonetheless, he knew what was right and was able, through persuasive, often inspiring rhetoric, to conclude a bloody and decisive Civil War and constitute the foundation for this great republic.... Yet access to basic medical care for all of our inhabitants is still not a reality in this country. There are many reasons for this, not the least of which is a long-standing, systematic, institutionalized racial discrimination.... An aura of inevitablitiy is upon us. It is not acceptable morally, ethically, or economically for so many of our people to be medically uninsured or seriously underinsured. We can solve this problem. We have the knowledge and the resources, the skills, the time, and the moral

    Duffey, T.A.; Goldman, A.; Farrar, C.R.

    1994-04-01

    Drift limits for reinforced-concrete shear walls are investigated by reviewing the open literature for appropriate experimental data. Drift values at ultimate are determined for walls with aspect ratios ranging up to a maximum of 3.53 and undergoing different types of lateral loading (cyclic static, monotonic static, and dynamic). Based on the geometry of actual nuclear power plant structures exclusive of containments and concerns regarding their response during seismic (i.e.,cyclic) loading, data are obtained from pertinent references for which the wall aspect ratio is less than or equal to approximately 1, and for which testing is cyclic in nature (typically displacement controlled). In particular, lateral deflections at ultimate load, and at points in the softening region beyond ultimate for which the load has dropped to 90, 80, 70, 60, and 50 percent of its ultimate value, are obtained and converted to drift information. The statistical nature of the data is also investigated. These data are shown to be lognormally distributed, and an analysis of variance is performed. The use of statistics to estimate Probability of Failure for a shear wall structure is illustrated

    A wide variety of infections can affect the chest wall including pyogenic, tuberculous, fungal, and some other unusual infections. These potentially life-threatening disorders are frequent especially among immunocompromised patients but often misdiagnosed by physical examination and radiographs. The purpose of this article is to describe the clinical and imaging features of these different chest wall infections according to the different imaging modalities with emphasis on ultrasound (US), computed tomography (CT), and magnetic resonance imaging (MRI). The outcome of chest wall infection depends on early diagnosis, severity of the immunosuppression, offending organism, and extent of infection. Because clinical findings and laboratory tests may be not contributive in immunocompromised patients, imaging plays an important role in the early detection and precise assessment of the disease. US, CT, and MRI are all useful: bone destruction is more accurately detected with CT whereas soft tissue involvement are better visualized with US and MRI. CT and US are also used to guide percutaneous biopsy and drainage procedures. MR images are helpful in pre-operative planning of extensive chest wall infections. (orig.)

  7. Granular packings with moving side walls

    International Nuclear Information System (INIS)

    Landry, James W.; Grest, Gary Stephen

    2004-01-01

    The effects of movement of the side walls of a confined granular packing are studied by discrete element, molecular dynamics simulations. The dynamical evolution of the stress is studied as a function of wall movement both in the direction of gravity as well as opposite to it. For all wall velocities explored, the stress in the final state of the system after wall movement is fundamentally different from the original state obtained by pouring particles into the container and letting them settle under the influence of gravity. The original packing possesses a hydrostaticlike region at the top of the container which crosses over to a depth-independent stress. As the walls are moved in the direction opposite to gravity, the saturation stress first reaches a minimum value independent of the wall velocity, then increases to a steady-state value dependent on the wall velocity. After wall movement ceases and the packing reaches equilibrium, the stress profile fits the classic Janssen form for high wall velocities, while some deviations remain for low wall velocities. The wall movement greatly increases the number of particle-wall and particle-particle forces at the Coulomb criterion. Varying the wall velocity has only small effects on the particle structure of the final packing so long as the walls travel a similar distance.

  10. Biofiltration of airborne VOCs with green wall systems-Microbial and chemical dynamics.

    Botanical air filtration is a promising technology for reducing indoor air contaminants, but the underlying mechanisms need better understanding. Here, we made a set of chamber fumigation experiments of up to 16 weeks of duration, to study the filtration efficiencies for seven volatile organic compounds (VOCs; decane, toluene, 2-ethylhexanol, α-pinene, octane, benzene, and xylene) and to monitor microbial dynamics in simulated green wall systems. Biofiltration functioned on sub-ppm VOC levels without concentration-dependence. Airflow through the growth medium was needed for efficient removal of chemically diverse VOCs, and the use of optimized commercial growth medium further improved the efficiency compared with soil and Leca granules. Experimental green wall simulations using these components were immediately effective, indicating that initial VOC removal was largely abiotic. Golden pothos plants had a small additional positive impact on VOC filtration and bacterial diversity in the green wall system. Proteobacteria dominated the microbiota of rhizosphere and irrigation water. Airborne VOCs shaped the microbial communities, enriching potential VOC-utilizing bacteria (especially Nevskiaceae and Patulibacteraceae) in the irrigation water, where much of the VOC degradation capacity of the biofiltration systems resided. These results clearly show the benefits of active air circulation and optimized growth media in modern green wall systems. © 2018 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

  11. Immobile defects in ferroelastic walls: Wall nucleation at defect sites

    Science.gov (United States)

    He, X.; Salje, E. K. H.; Ding, X.; Sun, J.

    2018-02-01

    Randomly distributed, static defects are enriched in ferroelastic domain walls. The relative concentration of defects in walls, Nd, follows a power law distribution as a function of the total defect concentration C: N d ˜ C α with α = 0.4 . The enrichment Nd/C ranges from ˜50 times when C = 10 ppm to ˜3 times when C = 1000 ppm. The resulting enrichment is due to nucleation at defect sites as observed in large scale MD simulations. The dynamics of domain nucleation and switching is dependent on the defect concentration. Their energy distribution follows the power law with exponents during yield between ɛ ˜ 1.82 and 2.0 when the defect concentration increases. The power law exponent is ɛ ≈ 2.7 in the plastic regime, independent of the defect concentration.

  13. Brick walls on the brane

    International Nuclear Information System (INIS)

    Medved, A J M

    2002-01-01

    The so-called 'brick-wall model' is a semiclassical approach that has been used to explain black hole entropy in terms of thermal matter fields. Here, we apply the brick-wall formalism to thermal bulk fields in a Randall-Sundrum brane world scenario. In this case, the black hole entity is really a string-like object in the anti-de Sitter bulk, while appearing as a Schwarzchild black hole to observers living on the brane. In spite of these exotic circumstances, we establish that the Bekenstein-Hawking entropy law is preserved. Although a similar calculation was recently considered in the literature, this prior study invoked a simplifying assumption (which we avoid) that cannot be adequately justified

    It is suggested that the phase transition of lambda phi 4 theory as a function of temperature coincides with the spontaneous appearance of domain walls. Based on one-loop calculations, T sub(c) = 4M/√ lambda is estimated as the temperature for these domains to because energetically favored, to be compared with T sub(c) = 4.9M/√ lambda from effective potential calculations (which are performed directly in the broken phase). Domain walls, as well as other Types of fluctuations, disorder the system above T sub(c), leading to =0. The critical exponent for the specific heat above T sub(c) is computed; and α=2/3 + 0 (√ lambda) is obtained. (Author) [pt

  15. Fast wall of thermonuclear device

    1990-01-01

    A protruding molten metal reservoir is disposed to a sealing vessel embedded in the armour tile of fast walls, and molten metal of low melting point such as tin, lead or alloy thereof is filled in the sealing vessel. The volume of the molten metal reservoir is determined such that the surface level of the molten metal is kept within the molten metal reservoir even when the sealed low melting point metal is solidified at room temperature. When the temperature is lowered during plasma interruption period and the sealed low melting molten metal is solidified to reduce the volume, most of the molten metal reservoir regioin constitutes a vacuum gap. However, the inner wall of the sealing vessel other than the molten metal reservior region can be kept into contact with the sealed metal. Accordingly, the temperature and the sublimation loss of the armour tile can be kept low even upon plasma heat application. (I.N.)

    The motion of a thin wall is treated in the case where the regions on either side of the wall have vacuum energy. This treatment generalises previous results involving domain walls in vacuum and also previous results involving the properties of false vacuum bubbles. The equation of state for a domain wall is{tau} = {sigma} where {tau} is the tension in the wall and {sigma} is the energy density. We consider the motion of a more general class of walls having equation of state {tau}{Gamma}{sigma} with 0{le}{Gamma}{le}1. Spherically symmetric and planar symmetric walls are examined. We also find the global structure of the wall spacetime. (author).

  19. Physics of resistive wall modes

    Igochine, V.

    2012-01-01

    The advanced tokamak regime is a promising candidate for steady-state tokamak operation which is desirable for a fusion reactor. This regime is characterized by a high bootstrap current fraction and a flat or reversed safety factor profile, which leads to operation close to the pressure limit. At this limit, an external kink mode becomes unstable. This external kink is converted into the slowly growing resistive wall mode (RWM) by the presence of a conducting wall. Reduction of the growth rate allows one to act on the mode and to stabilize it. There are two main factors which determine the stability of the RWM. The first factor comes from external magnetic perturbations (error fields, resistive wall, feedback coils, etc). This part of RWM physics is the same for tokamaks and reversed field pinch configurations. The physics of this interaction is relatively well understood and based on classical electrodynamics. The second ingredient of RWM physics is the interaction of the mode with plasma flow and fast particles. These interactions are particularly important for tokamaks, which have higher plasma flow and stronger trapped particle effects. The influence of the fast particles will also be increasingly more important in ITER and DEMO which will have a large fraction of fusion born alpha particles. These interactions have kinetic origins which make the computations challenging since not only particles influence the mode, but also the mode acts on the particles. Correct prediction of the ‘plasma–RWM’ interaction is an important ingredient which has to be combined with external field's influence (resistive wall, error fields and feedback) to make reliable predictions for RWM behaviour in tokamaks. All these issues are reviewed in this paper. (special topic)

  16. Thermal insulation properties of walls

    Directory of Open Access Journals (Sweden)

    Zhukov Aleksey Dmitrievich

    2014-05-01

    Full Text Available Heat-protective qualities of building structures are determined by the qualities of the used materials, adequate design solutions and construction and installation work of high quality. This rule refers both to the structures made of materials similar in their structure and nature and mixed, combined by a construction system. The necessity to ecaluate thermal conductivity is important for a product and for a construction. Methods for evaluating the thermal protection of walls are based on the methods of calculation, on full-scale tests in a laboratory or on objects. At the same time there is a reason to believe that even deep and detailed calculation may cause deviation of the values from real data. Using finite difference method can improve accuracy of the results, but it doesn’t solve all problems. The article discusses new approaches to evaluating thermal insulation properties of walls. The authors propose technique of accurate measurement of thermal insulation properties in single blocks and fragments of walls and structures.

  17. Alternative to domain wall fermions

    International Nuclear Information System (INIS)

    Neuberger, H.

    2002-01-01

    An alternative to commonly used domain wall fermions is presented. Some rigorous bounds on the condition number of the associated linear problem are derived. On the basis of these bounds and some experimentation it is argued that domain wall fermions will in general be associated with a condition number that is of the same order of magnitude as the product of the condition number of the linear problem in the physical dimensions by the inverse bare quark mass. Thus, the computational cost of implementing true domain wall fermions using a single conjugate gradient algorithm is of the same order of magnitude as that of implementing the overlap Dirac operator directly using two nested conjugate gradient algorithms. At a cost of about a factor of two in operation count it is possible to make the memory usage of direct implementations of the overlap Dirac operator independent of the accuracy of the approximation to the sign function and of the same order as that of standard Wilson fermions

  18. Method of constructing shielding wall

    International Nuclear Information System (INIS)

    Nagao, Tetsuya.

    1990-01-01

    For instance, surfaces of lead particles each formed into a sphere of about 0.5 to 0.3 mm grain size are coated with a coating material of a synthetic resin comprising a polymeric material such as teflon. Subsequently, the floated lead particle are kneaded with concrete materials and then poured into a molding die by way of a hose. After coagulation, the molding die is removed to complete shielding walls in which lead particles are scattered substantially at an equal distance. In this way, since the lead particles are mixed into the shielding walls, shielding effects can be improved by so much as the lead particles are mixed, thereby enabling to reduce the thickness of the shielding walls. Further, since the lead particles are coated with the coating material, the lead particles are insulated from the concrete materials, thereby enabling to prevent the corrosion of the lead particles. Furthermore, since the lead particles and the concrete materials can be transported with ease, operation labors can be reduced. (T.M.)

  19. Flooding Effect on Earth Walls

    Directory of Open Access Journals (Sweden)

    Meysam Banimahd

    2010-12-01

    Full Text Available Earth building is a sustainable, environmentally friendly and economical method of construction that has been used worldwide for many centuries. For the past three decades, earth has seen a revival as a building material for a modern construction method due to its benefits in terms of low carbon content, low cost and energy involved during construction, as well as the fact that it is a sustainable technology of building. Climate change is influencing precipitation levels and patterns around the world, and as a consequence, flood risk is increasing rapidly. When flooding occurs, earth buildings are exposed to water by submersion, causing an increase in the degree of saturation of the earth structures and therefore a decrease of the suction between particles. This study investigated the effect of cycles of flooding (consecutive events of flooding followed by dry periods on earth walls. A series of characterization tests were carried out to obtain the physical and mechanical properties of the studied earth material. In a second stage, Flooding Simulation Tests (FST were performed to explore the earth walls’ response to repeated flooding events. The results obtained for the tested earth wall/samples with reinforced material (straw reveal hydraulic hysteresis when wall/samples are subject to cycles of wetting and drying.

    The yeast spore wall is an excellent model to study the assembly of an extracellular macromolecule structure. In the present study, mutants defective in β-1,6-glucan synthesis, including kre1∆, kre6∆, kre9∆ and big1∆, were sporulated to analyse the effect of β-1,6-glucan defects on the spore wall. Except for kre6∆, these mutant spores were sensitive to treatment with ether, suggesting that the mutations perturb the integrity of the spore wall. Morphologically, the mutant spores were indistinguishable from wild-type spores. They lacked significant sporulation defects partly because the chitosan layer, which covers the glucan layer, compensated for the damage. The proof for this model was obtained from the effect of the additional deletion of CHS3 that resulted in the absence of the chitosan layer. Among the double mutants, the most severe spore wall deficiency was observed in big1∆ spores. The majority of the big1∆chs3∆ mutants failed to form visible spores at a higher temperature. Given that the big1∆ mutation caused a failure to attach a GPI-anchored reporter, Cwp2-GFP, to the spore wall, β-1,6-glucan is involved in tethering of GPI-anchored proteins in the spore wall as well as in the vegetative cell wall. Thus, β-1,6-glucan is required for proper organization of the spore wall. Copyright © 2017 John Wiley & Sons, Ltd. Copyright © 2017 John Wiley & Sons, Ltd.

    We discovered a previously unobserved mechanism by which air bubbles detach from vibrating walls in glasses containing water. Chaotic oscillation and subsequent water jets appeared when a wall vibrated at greater than a critical level. Wave forms were developed at water-air interface of the bubble by the wall vibration, and water jets were formed when sufficiently grown wave-curvatures were collapsing. Droplets were pinched off from the tip of jets and fell to the surface of the glass. When the solid-air interface at the bubble-wall attachment point was completely covered with water, the bubble detached from the wall. The water jets were mainly generated by subharmonic waves and were generated most vigorously when the wall vibrated at the volume resonant frequency of the bubble. Bubbles of specific size can be removed by adjusting the frequency of the wall's vibration.

  7. Near-wall serpentine cooled turbine airfoil

    2013-09-17

    A serpentine coolant flow path (54A-54G) formed by inner walls (50, 52) in a cavity (49) between pressure and suction side walls (22, 24) of a turbine airfoil (20A). A coolant flow (58) enters (56) an end of the airfoil, flows into a span-wise channel (54A), then flows forward (54B) over the inner surface of the pressure side wall, then turns behind the leading edge (26), and flows back along a forward part of the suction side wall, then follows a loop (54E) forward and back around an inner wall (52), then flows along an intermediate part of the suction side wall, then flows into an aft channel (54G) between the pressure and suction side walls, then exits the trailing edge (28). This provides cooling matched to the heating topography of the airfoil, minimizes differential thermal expansion, revives the coolant, and minimizes the flow volume needed.

  8. The origin of 'Great Walls'

    International Nuclear Information System (INIS)

    Shandarin, Sergei F.

    2009-01-01

    A new semi-analytical model that explains the formation and sizes of the 'great walls' - the largest structures observed in the universe is suggested. Although the basis of the model is the Zel'dovich approximation it has been used in a new way very different from the previous studies. Instead of traditional approach that evaluates the nonlinear density field it has been utilized for identification of the regions in Lagrangian space that after the mapping to real or redshift space (depending on the kind of structure is studied) end up in the regions where shell-crossing occurs. The set of these regions in Lagrangian space form the progenitor of the structure and after the mapping it determines the pattern of the structure in real or redshift space. The particle trajectories have crossed in such regions and the mapping is no longer unique there. The progenitor after mapping makes only one stream in the multi-stream flow regions therefore it does not comprise all the mass. Nevertheless, it approximately retains the shape of the structure. The progenitor of the structure in real space is determined by the linear density field along with two non-Gaussian fields derived from the initial potential. Its shape in Eulerian space is also affected by the displacement field. The progenitor of the structure in redshift space also depends on these fields but in addition it is strongly affected by two anisotropic fields that determine the pattern of great walls as well as their huge sizes. All the fields used in the mappings are derived from the linear potential smoothed at the current scale of nonlinearity which is R nl = 2.7 h −1 Mpc for the adopted parameters of the ΛCDM universe normalized to σ 8 = 0.8. The model predicts the existence of walls with sizes significantly greater than 500 h −1 Mpc that may be found in sufficiently large redshift surveys

    In this chapter we review numerous diagnostics capable of measurements at or near the first wall, many of which contribute information useful for safe operation of a tokamak. There are sections discussing infrared cameras, visible and VUV cameras, pressure gauges and RGAs, Langmuir probes, thermocouples, and erosion and deposition measurements by insertable probes and quartz microbalance. Also discussed are dust measurements by electrostatic detectors, laser scattering, visible and IR cameras, and manual collection of samples after machine opening. In each case the diagnostic is discussed with a view toward application to a burning plasma machine such as ITER

    We unveil the existence of a non-trivial Berry phase associated to the dynamics of a quantum particle in a one dimensional box with moving walls. It is shown that a suitable choice of boundary conditions has to be made in order to preserve unitarity. For these boundary conditions we compute explicitly the geometric phase two-form on the parameter space. The unboundedness of the Hamiltonian describing the system leads to a natural prescription of renormalization for divergent contributions arising from the boundary.

    concrete has a memory. It stores the construction sequences. It shows what it is made of and how it is made. The texture of the formwork, the color difference of the pours, and the shadows of the metal ties combine to layer the beauty of concrete. The aim of this study is to explore the instruments of a concrete surface in order to enhance this multi-sensory experience. This study began with the design of a concrete wall and evolved into the design of a single-family home. MARCH

    An analytic parametric scoping tool has been developed for application to first wall (FW) design problems. Both thermal and disruption force effects are considered. For the high heat flux and high disruption load conditions expected in the International Thermonuclear Experimental Reactor (ITER) device, Vanadium alloy and dispersion-strengthened copper offer the best stress margins using a somewhat flattened plasma-facing configuration. Ferritic steels also appear to have an acceptable stress margin, whereas the conventional stainless steel 316 does not appear feasible. If a full semicircle shape FW is required, only the Vanadium and ferritic steel alloy have acceptable solutions

    This paper describes an investigation into whether estimates of attenuation in the flat sidewalls of the tunnel for the MC main ring can be based on a simple point-source/line-of-sight model. Having seen the limitations of such a model, an alternative is proposed where the main radiation source is not the initial object struck by the beam but the plane source provided by the first interactions of secondaries from the target in the shield-wall. This is shown to have a closer relation to reality than the point-source/line-of-sight model. (author)

  15. Systems and synthetic biology approaches to alter plant cell walls and reduce biomass recalcitrance.

    Fine-tuning plant cell wall properties to render plant biomass more amenable to biofuel conversion is a colossal challenge. A deep knowledge of the biosynthesis and regulation of plant cell wall and a high-precision genome engineering toolset are the two essential pillars of efforts to alter plant cell walls and reduce biomass recalcitrance. The past decade has seen a meteoric rise in use of transcriptomics and high-resolution imaging methods resulting in fresh insights into composition, structure, formation and deconstruction of plant cell walls. Subsequent gene manipulation approaches, however, commonly include ubiquitous mis-expression of a single candidate gene in a host that carries an intact copy of the native gene. The challenges posed by pleiotropic and unintended changes resulting from such an approach are moving the field towards synthetic biology approaches. Synthetic biology builds on a systems biology knowledge base and leverages high-precision tools for high-throughput assembly of multigene constructs and pathways, precision genome editing and site-specific gene stacking, silencing and/or removal. Here, we summarize the recent breakthroughs in biosynthesis and remodelling of major secondary cell wall components, assess the impediments in obtaining a systems-level understanding and explore the potential opportunities in leveraging synthetic biology approaches to reduce biomass recalcitrance.

  16. Anterior chest wall examination reviewed

    Directory of Open Access Journals (Sweden)

    2011-09-01

    Full Text Available Anterior chest wall involvement is not infrequently observed within inflammatory arthropaties, particularly if one considers seronegative spondiloarthritides and SAPHO syndrome. Physical examination is unreliable and conventional X-rays analysis is an unsatisfactory tool during diagnostic work-up of this region. Scintigraphic techniques yield informations both on the activity and on the anatomical extent of the disease while computerized tomography visualize the elementary lesions, such as erosions, which characterize the process. Moreover, when available, magnetic resonance imaging couple the ability to finely visualize such lesions with the possibility to show early alterations and to characterize the “activity” of the disease, presenting itself as a powerful tool both for diagnosis and follow-up. This review briefly shows the applications of imaging techniques for the evaluation of the anterior chest wall focusing on what has been done in the SAPHO syndrome which can be considered prototypical for this regional involvement since it is the osteo-articular target mainly affected by the disease.

  17. Reactor wall in thermonuclear device

    1988-01-01

    Purpose: To always monitor the life of armours in reactor walls and automatically shutdown the reactor if it should be operated in excess of the limit of use. Constitution: Monitoring material of lower melting point than armours (for example beryllium pellets) as one of the reactor wall constituents of a thermonuclear device are embedded in a region leaving the thickness corresponding to the allowable abrasion of the armour. In this structure, if the armours are abrased due to particle loads of a plasma and the abrasion exceeds a predetermined allowable level, the monitoring material is exposed to the plasma and melted and evaporated. Since this can be detected by impurity monitors disposed in the reactor, it is possible to recognize the limit for the working life of the armours. If the thermonuclear reactor should be operated accidentally exceeding the life of the armours, since a great amount of the monitoring materials have been evaporated, they flow into the plasma to increase the plasma radiation loss thereby automatically eliminate the plasma.

  18. Immersion Refractometry of Isolated Bacterial Cell Walls

    Marquis, Robert E.

    1973-01-01

    Immersion-refractometric and light-scattering measurements were adapted to determinations of average refractive indices and physical compactness of isolated bacterial cell walls. The structures were immersed in solutions containing various concentrations of polymer molecules that cannot penetrate into wall pores, and then an estimate was made of the polymer concentration or the refractive index of the polymer solution in which light scattering was reduced to zero. Because each wall preparation was heterogeneous, the refractive index of the medium for zero light scattering had to be estimated by extrapolation. Refractive indices for walls suspended in bovine serum albumin solutions ranged from 1.348 for walls of the rod form of Arthrobacter crystallopoietes to 1.382 for walls of the teichoic acid deficient, 52A5 strain of Staphylococcus aureus. These indices were used to calculate approximate values for solids content per milliliter, and the calculated values agreed closely with those estimated from a knowledge of dextran-impermeable volumes per gram, dry weight, of the walls. When large molecules such as dextrans or serum albumin were used for immersion refractometry, the refractive indices obtained were for entire walls, including both wall polymers and wall water. When smaller molecules that can penetrate wall pores to various extents were used with Micrococcus lysodeikticus walls, the average, apparent refractive index of the structures increased as the molecular size of probing molecules was decreased. It was possible to obtain an estimate of 1.45 to 1.46 for the refractive index of wall polymers, predominantly peptidoglycans in this case, by extrapolating the curve for refractive index versus molecular radius to a value of 0.2 nm, the approximate radius of a water molecule. This relatively low value for polymer refractive index was interpreted as evidence in favor of the amorphous, elastic model of peptidoglycan structure and against the crystalline, rigid

  20. Development of a novel oral vaccine against Mycobacterium avium paratuberculosis and Johne disease

    2010-01-01

    Mycobacterium avium subsp. paratuberculosis (MAP) is the etiological agent of Johne disease, a granulomatous enteritis of cattle and other domesticated and wild ruminant species. Johne disease is prevalent worldwide and has a significant impact on the global agricultural economy. Current vaccines against Johne are insufficient in stemming its spread, and associated side-effects prevent their widespread use in control programs. Effective and safe vaccine strategies are needed. The main purpose of this paper is to propose and evaluate the development of a novel oral subunit-vaccine using a patho-biotechnological approach. This novel strategy, which harnesses patho-genetic elements from the intracellular pathogen Listeria monocytogenes, may provide a realistic route towards developing an effective next generation subunit vaccine against Johne disease and paratuberculosis.
