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

  13. Spiro K. Antiochos Receives 2013 John Adam Fleming Medal: Citation

    Science.gov (United States)

    Klimchuk, James A.

    2014-01-01

    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.

  15. New insights into canted spiro carbon interstitial in graphite

    Science.gov (United States)

    EL-Barbary, A. A.

    2017-12-01

    The self-interstitial carbon is the key to radiation damage in graphite moderator nuclear reactor, so an understanding of its behavior is essential for plant safety and maximized reactor lifetime. The density functional theory is applied on four different graphite unit cells, starting from of 64 carbon atoms up to 256 carbon atoms, using AIMPRO code to obtain the energetic, athermal and mechanical properties of carbon interstitial in graphite. This study presents first principles calculations of the energy of formation that prove its high barrier to athermal diffusion (1.1 eV) and the consequent large critical shear stress (39 eV-50 eV) necessary to shear graphite planes in its presence. Also, for the first time, the gamma surface of graphite in two dimensions is calculated and found to yield the critical shear stress for perfect graphite. Finally, in contrast to the extensive literature describing the interstitial of carbon in graphite as spiro interstitial, in this work the ground state of interstitial carbon is found to be canted spiro interstitial.

  17. Richard's back: death, scoliosis and myth making.

    Science.gov (United States)

    Lund, Mary Ann

    2015-12-01

    The body of a mediaeval monarch was always under scrutiny, and Richard III's was no exception. In death, however, his body became subject to new forms of examination and interpretation: stripped naked after the battle of Bosworth, his corpse was carried to Leicester and exhibited before being buried. In 2012, it was rediscovered. The revelation that Richard suffered from scoliosis prompts this article to re-evaluate the historical sources about Richard's physique and his posthumous reputation. This article argues that Richard's death and his myth as 'crookback' are inextricably linked and traces attitudes to spinal curvature in the early modern period. It also considers how Shakespeare represented Richard as deformed, and aspects of performance history which suggest physical vulnerability. It then considers Richard's scoliosis from the perspective of medical history, reviewing classical accounts of scoliosis and arguing that Richard was probably treated with a mixture of axial traction and pressure. It demonstrates from the evidence of Richard's medical household that he was well placed to receive hands-on therapies and considers in particular the role of his physician and surgeon, William Hobbes. Finally, it shows how the case of Richard III demonstrates the close relationship between politics and medicine in the period and the contorted process of historical myth making.

    1999-01-01

    The Richards Barrier is one of the design features of the repository to be considered for the License Application (LA), Richards was a soil scientist who first described the diversion of moisture between two materials with different hydrologic properties. In this report, a Richards Barrier is a special type of backfill with a fine-grained material (such as sand) overlaying a coarse-grained material (such as gravel). Water that enters an emplacement drift will first encounter the fine-grained material and be transported around the coarse-grained material covering the waste package, thus protecting the waste package from contact with most of the groundwater. The objective of this report is to discuss the benefits and liabilities to the repository by the inclusion of a Richards Barrier type backfill in emplacement drifts. The Richards Barrier can act as a barrier to water flow, can reduce the waste package material dissolution rate, limit mobilization of the radionuclides, and can provide structural protection for the waste package. The scope of this report is to: (1) Analyze the behavior of barrier materials following the intrusion of groundwater for influxes of 1 to 300 mm per year. The report will demonstrate diversion of groundwater intrusions into the barrier over an extended time period when seismic activity and consolidation may cause the potential for liquefaction and settlement of the Richards Barrier. (2) Review the thermal effects of the Richards Barrier on material behavior. (3) Analyze the effect of rockfall on the performance of the Richards Barrier and the depth of the barrier required to protect waste packages under the barrier. (4) Review radiological and heating conditions on placement of multiple layers of the barrier. Subsurface Nuclear Safety personnel will perform calculations to determine the radiation reduction-time relationship and shielding capacity of the barrier. (5) Evaluate the effects of ventilation on cooling of emplacement drifts and

    Full Text Available Homophthalic anhydride reacts with different aromatic amines to produce N-substituted homophthalimides. Bromination of the latter produces 4,4-dibromo-homophthalimide derivatives that can be used as precursors for spiro-derivatives. The dibromo derivatives react with different binucleophilic reagents to produce several spiro-isoquinoline derivatives. Reaction of the dibromo derivatives with malononitrile produces dicyanomethylene derivatives which react with different binucleophiles to produce new spiro-derivatives. Structures of the newly synthesized compounds are proved using spectroscopic methods such as IR, 1H-NMR and 13C-NMR. The newly synthesized compounds were tested for their antimicrobial and antioxidant activities, showing weak or no antimicrobial activity. On the other hand select compounds showed promising antioxidant activities.

    Full Text Available The present paper describes a total synthesis of racemic β-chamigrene (1, a sesquiterpene with a spiro[5.5]undecane carbon framework. Compared with previously reported β-chamigrene syntheses, we were able to reduce the total number of reaction steps, which also resulted in a significant improvement of the overall yield. The commercially available ketone 6-methylhept-5-en-2-one was transformed by known simple procedures into 3,3-dimethyl-2-methylenecyclohexanone. This reacted with isoprene by a Diels-Alder reaction to give a spiro ketone. An olefination reaction on this compound gave the target molecule.

    Science.gov (United States)

    Jannuzi, Buell Tomasson; Bechtold, Jill

    2004-12-01

    Richard Joseph Elston, known for his development of innovative astronomical instrumentation, died on 26 January 2004 in Gainesville, Florida, after a four-year battle with Hodgkin's lymphoma. A professor of astronomy at the University of Florida, Richard had an unusually broad range of interests and skills, and a willingness to share his passion for astronomy with others, which made him a highly valued member of the astronomical community. Born 1 July 1960, in Albuquerque, New Mexico, Richard was the son of a geologist father and journalist mother. His childhood interest in astronomy and instrumentation matured as he majored in physics and astronomy at the University of New Mexico (BS, 1983) under the mentorship of Michael Zeilik. Richard pursued his PhD in astronomy at the University of Arizona and earned his degree in 1988. He pioneered the use of IR arrays for deep imaging surveys of the sky to study galaxy formation, and completed his thesis Search for Rapidly Forming Galaxies at High Redshift under the direction of George Rieke. Richard's graduate work included the first detection of galaxies at intermediate redshifts with evolved populations too red to have been identifiable from optical imaging surveys alone. In the Astrophysical Journal Letters in 1988, he, George Rieke, and Marcia Rieke reported the discovery of this new class of galaxies, now known as EROs (Extremely Red Objects), important as the possible progenitors of present day elliptical galaxies. Following post-doctoral positions at Kitt Peak National Observatory from 1988 to 1991 and at the Observatories of the Carnegie Institution of Washington from 1991 to 1992, Richard joined the scientific staff of Cerro Tololo Inter-American Observatory in Chile, part of the NSF's National Optical Astronomy Observatory. By 1994, he had become head of CTIO's IR instrumentation program and was leading the development of new instruments for the US astronomical community. In 1996, Richard married astronomer

  14. Spiro-OMeTAD single crystals: Remarkably enhanced charge-carrier transport via mesoscale ordering

    KAUST Repository

    Shi, Dong

    2016-04-15

    We report the crystal structure and hole-transport mechanism in spiro-OMeTAD [2,2′,7,7′-tetrakis(N,N-di-p-methoxyphenyl-amine)9,9′-spirobifluorene], the dominant hole-transporting material in perovskite and solid-state dye-sensitized solar cells. Despite spiro-OMeTAD’s paramount role in such devices, its crystal structure was unknown because of highly disordered solution-processed films; the hole-transport pathways remained ill-defined and the charge carrier mobilities were low, posing a major bottleneck for advancing cell efficiencies. We devised an antisolvent crystallization strategy to grow single crystals of spiro-OMeTAD, which allowed us to experimentally elucidate its molecular packing and transport properties. Electronic structure calculations enabled us to map spiro-OMeTAD’s intermolecular charge-hopping pathways. Promisingly, single-crystal mobilities were found to exceed their thin-film counterparts by three orders of magnitude. Our findings underscore mesoscale ordering as a key strategy to achieving breakthroughs in hole-transport material engineering of solar cells.

  15. Study on optoelectronic properties of Spiro-CN for developing an efficient OLED

    Science.gov (United States)

    Mishra, Ashok Kumar

    2018-05-01

    There are a class of organic molecules and polymers which exhibit semiconductor behavior because of nearly free conjugate π-electrons. Hopping of these electrons in molecules forms different excited singlet and triplet states named as excitons. Some of these organic molecules can be set to emit photons by triplet-singlet excitonic transition via a process called Thermally Activated Delayed Fluorescence (TADF) which is exploited for designing the Organic Light Emitting diode (OLED.) Spiro-CN (spirobifluorene skeletons) Spiro is one of these reported noble metal-free TADF molecules which offers unique optical and electronic properties arising from the efficient transition and reverse intersystem crossing between the lowest singlet (S) and triplet (T) excited states. Its ability to harvest triplet excitons for fluorescence through facilitated reverse intersystem crossing (T→S) could directly impact their properties and performances, which is attractive for a wide variety of low-cost optoelectronic device. In the present study, the Spiro-CN compounds have been taken up for the investigation of various optoelectronic properties including the thermally activated delayed fluorescence (TADF) by using the Koopmans Method and Density Functional Theory. The present study discusses the utility of the Spiro-CN organic semiconductor as a suitable TADF material essential for developing an efficient Organic Light Emitting Diode (OLED).

  17. Method of lines solution of Richards` equation

    Energy Technology Data Exchange (ETDEWEB)

    Kelley, C.T.; Miller, C.T.; Tocci, M.D.

    1996-12-31

    We consider the method of lines solution of Richard`s equation, which models flow through porous media, as an example of a situation in which the method can give incorrect results because of premature termination of the nonlinear corrector iteration. This premature termination arises when the solution has a sharp moving front and the Jacobian is ill-conditioned. While this problem can be solved by tightening the tolerances provided to the ODE or DAE solver used for the temporal integration, it is more efficient to modify the termination criteria of the nonlinear solver and/or recompute the Jacobian more frequently. In this paper we continue previous work on this topic by analyzing the modifications in more detail and giving a strategy on how the modifications can be turned on and off in response to changes in the character of the solution.

    This text is a portrayal of one of the greatest scientists of the late 20th-century, which also provides a picture of the significant physics of the period. It combines personal anecdotes, writings and recollections with narrative. Richard Feynman's career included: war-time work on the atomic bomb at Los Alamos; a theory of quantum mechanics for which he won the Nobel prize; and major contributions to the sciences of gravity, nuclear physics and particle theory. In 1986, he was able to show that the Challenger disaster was due to the effect of cold on the booster rocket rubber sealings.

    Described by his peers as the "finest physicist of his generation," Richard Feynman defied scientist stereotypes. This brash New York-born American physicist startled the more conservative giants of European physics with his endless ability to improvise. Indeed, later in life, Feynman became an accomplished bongo player. Feynman's legacy to physics was his ability to simplify complex equations and clarify fundamental principles through the use of graphs. He developed the theory of quantum electrodynamics, which illustrates the behavior of electrically charged particles, such as elect

    Richard T. Cox's contributions to the foundations of probability theory and inductive logic are not generally appreciated or understood. This paper reviews his life and accomplishments, especially those in his book The Algebra of Probable Inference and his final publication Inference and Inquiry which, in this author's opinion, has the potential to influence in a significant way the design and analysis of self organizing systems which learn from experience. A simple application to the simulation of a neuron is presented as an example of the power of Cox's contribution.

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

  7. Seeing Scale: Richard Dunn’s Structuralism

    Keith Broadfoot

    2012-11-01

    Full Text Available Writing on the occasion of a retrospective of Richard Dunn’s work, Terence Maloon argued that ‘structuralism had an important bearing on virtually all of Richard Dunn’s mature works’, with ‘his modular, “crossed” formats’ being the most obvious manifestation of this. In this article I wish to reconsider this relation, withdrawing from a broad consideration of the framework of structuralism to focus on some of the quite particular ideas that Lacan proposed in response to structuralism. Beginning from a pivotal painting in the 1960s that developed out of Dunn’s experience of viewing the work of Barnett Newman, I wish to suggest a relation between the ongoing exploration of the thematic of scale in Dunn’s work and the idea of the symbolic that Lacan derives from structuralist thought. This relation, I argue, opens up a different way of understanding the art historical transition from Minimalism to Conceptual art.

    Full Text Available The era in which we live, characterized by multiculturalism and complexity, it is a time when it is clear the difficulty of man to orient and to choose their own way. It’s the time of the fall of every certainty, is the era of “post”, after the tradition, after metaphysics, after the truth, and that requires more effort than any other constant reflection. The neopragmatismo seems to be an effective investigative tool for conducting this reflection and a vantage point to carry on a conversation around the issues of education. In particular, the author intended to refer to the work of Richard Rorty, the author who more than others reflected on the encounter between two important pragmatist tradition: that of classical pragmatism and the “continental” or responsible for the development of a new European concept of truth, understood as a critical and interpretative.

    Full Text Available This paper makes accesible a new transcription of Richard Spruce’s vocabulary of the Sechura language. Collected in the mid-19th century by the British botanist, it constitutes one of only two sources of data for this language of northernmost Peru. A comparison of the original with previously published versions shows serious errors in transcription, in particular in those of Otto von Buchwald and Jacinto Jijón y Camaaño. The article also discusses the probable circumstances of data collection and the publication history of the hitherto known version, and concludes with some first observations on the significance of Spruce’s wordlist for elucidating the linguistic history of the region, in particular with regard to the question of the linguistic situation at Olmos.

    Full Text Available I try to show that Richard Rorty, although is not a moral philosopher like Kant, nerveless, has moral philosophy that must be taken seriously. Rorty was not engaged with moral philosophy in the systematic manner common among leading modern and contemporary moral philosophers. This paper has two parts: first part, in brief, is concerned with principles of his philosophy such as anti-essentialism, Darwinism, Freudism, and historicism. Second part which be long and detailed, considers many moral themes in Rorty's thought such as critique of Kantian morality, solidarity, moral progress, cruelty and concept of other, etc. Subsequently, I will try to answer the research question of the article namely, has Rorty a moral philosophy?

    Wilking, Bruce

    2011-12-01

    Richard D. Schwartz, Professor Emeritus of Astronomy, died at his home in Sequim, WA, after a nearly 3 year battle against pancreatic cancer. Richard was born in Pretty Prairie, Kansas. He was active in sports and band and graduated in 1959. After completing a BS at Kansas State, and a Master's degree in Divinity at Union Seminary in NY, he further studied astrophysics, receiving his doctorate from University of Washington in 1973. When Dick arrived at the University of Missouri-St. Louis in 1975, he was the only astronomer in the Department of Physics. He built the astronomy program and initiated the B.S. in physics with an astrophysics option that the majority of physics majors choose. Dick was a wonderful teacher and provided outstanding leadership to the campus. He designed and provided oversight on the construction of the campus observatory that was completed in 1981. Since that time the observatory has served as both a teaching and research facility. It is also used for monthly public open houses that draw hundreds of people annually to the campus to view the moon, stars, and planets. Upon his retirement in 2003, the Board of Curators approved naming the campus observatory the "Richard D. Schwartz Observatory" in honor of his distinctive service to the University of Missouri-St. Louis. Just as important as Dick's service to promote public interest in astronomy was his effort to make the campus observatory a research facility. Dick equipped and maintained the observatory with state-of-art detectors that allowed students to get their first taste of scientific research. From 1991-2003, he managed the campus program for the NASA/Missouri Space Grant Consortium and mentored over 30 research students in projects at the observatory. Some of the results have been published in astronomical journals. Many of those students went on to graduate schools and several have achieved tenure and distinction at major universities. In addition to Dick's service to the University

    Full Text Available A new series of spiro-oxindoles that were identified based upon their ability to inhibit methionine tRNA synthase (PDB ID: 1PFV and glucosamine-6-phosphate synthase (PDB ID: 1JXA enzymes in virtual screening was synthesized by a three-component 1,3-dipolar cycloaddition method. The reaction proceeds through the formation of azomethine ylides generated in situ by the decarboxylative condensation of isatin and amino acids with dipolarophile chalcones. These compounds are active against Staphylococcus aureus, Escherichia coli, Aspergillus niger and Aspergillus flavus, supporting the in silico screening. In addition, their antitubercular activity was assessed using the MABA method. The compounds 3′-[(4-fluorophenylcarbonyl]-4′-phenylspiro[indole-3,2′-pyrrolidin]-2(1H-one 3a, 4′-(4-bromophenyl-3′-[(4-fluorophenylcarbonyl]-5′-(hydroxymethyl spiro[indole-3,2′-pyrrolidin]-2(1H-one 3e and 4′-(4-chlorophenyl-3′-[(4-fluorophenylcarbonyl]-5′-(2-methylpropylspiro[indole-3,2′-pyrrolidin]-2(1H-one 3g are potent molecules with MIC of 0.8 μg/mL.

    Reaction of aryl- and benzylsulfanopyridinium amidates bearing a methyl group in position 6 with 2 equiv of diphenylketene afforded a spiro-fused ring system: azoniabenzo[de]fluorine. By use of an excess amount of ketene, a distinct reaction was observed via which a 1H-pyrrolo[3,2-b]pyridin-2(3H)-one derivative was furnished. The structure of the tetracyclic spiro-fused ring system was unambiguously confirmed by X-ray diffraction, and its formation was rationalized by DFT calculations.

  17. Richard Murphy: a life in writing

    Directory of Open Access Journals (Sweden)

    E. Meihuizen

    2006-07-01

    Full Text Available The Irish poet Richard Murphy published his autobiography “The kick: a life among writers” in 2003. From a slightly different perspective the subtitle of this work could be rewritten as “A life in writing” since it is an account of the agencies that moulded a life devoted to creative writing which forms the book’s essential impetus. The memoir is based on notebooks which Murphy kept throughout his life “to hold the scraps of verse, elusive images, dreams, desires and revelations” to be developed into poetry. Apart from contextualising his poetry by registering the relationships, circumstances and landscapes from which it germinated, Murphy also tells of the creative process itself and the personal poetics underlying this process. This article explores what is regarded as the central determining feature of Murphy’s identity as poet, namely the relationship between the creative self and a particular place, where the concept of “place” is seen as a cultural palimpsest which represents not only physical qualities, but also the shaping and development of the landscape through time according to a certain way of life.

  18. Richard Murphy: Autobiography and the Connemara landscape

    Directory of Open Access Journals (Sweden)

    Elsa Meihuizen

    2015-08-01

    Full Text Available It could be argued that an important feature of Richard Murphy’s work, and of his identity as a poet is the relationship between the creative self and a particular place, where ‘place’ should be understood as referring not just to physical qualities of the natural environment, but in a broader sense to denote an environment in which everything is interrelated and connected, and in which there is no sharp division between the natural and the human. The landscape providing inspiration for Murphy’s poetic imagination is the landscapes and seascapes of Connemara in north-west Ireland. In 1959 he settled in this environment which was to be his base for the next 20 years and from this period and this location emanated the bulk of his poetic oeuvre. For Murphy committing to a life of writing poetry necessarily means being in the Connemara landscape. Returning to this environment in adulthood represents a quest for recovering childhood feelings, of belonging and love, as connected to particular places. Murphy’s Connemara poems could be read as an account of this process of re-placement, as a type of autobiographical text in which the artist creates a ‘double portrait’: in writing about the landscape he also writes about himself, creating a place-portrait which is, at the same time, a self-portrait.

    to systematic consideration. Swedberg attributes this strange absence to what he sees as the miserable state of contemporary social theory. We must, he claims, avoid two misconceptions: ‘empiricism’ and ‘abstract theory’. In the first case, theory is reduced to the task of summarizing the outcome of empirical......It is a rare event when a new general field of research opens up within sociology. However, with this book, Richard Swedberg intends to do just that. It is not just another book on social theory. It is a book on ‘theorizing’. And that makes all the difference. Swedberg has chosen the term ‘art......’, but also ‘craft’, to emphasize the practical side of doing theory. This topic has been strangely absent, not just in sociology but in the social sciences in general. In order to see this absence, we should ask ourselves how education in sociology is conventionally organized. The answer is by a taken...

  20. Nanostructured TiO2/CH3NH3PbI3 heterojunction solar cells employing spiro-OMeTAD/Co-complex as hole-transporting material

    KAUST Repository

    2013-01-01

    For using 2,2′,7,7′-tetrakis(N,N′-di-p- methoxyphenylamine)-9,9′-spirobifluorene (spiro-OMeTAD) as a hole conductor in solar cells, it is necessary to improve its charge-transport properties through electrochemical doping. With the aim of fabricating efficient mesoscopic TiO2/CH3NH3PbI3 heterojunction solar cells, we used tris[2-(1H-pyrazol-1-yl)-4-tert- butylpyridine)cobalt(iii) tris(bis(trifluoromethylsulfonyl) imide)] (FK209) as a p-dopant for spiro-OMeTAD. The mixture of spiro-OMeTAD, FK209, lithium bis(trifluoromethylsulfonyl)imide (Li-TFSI), and 4-tert-butylpyridine (TBP) exhibited significantly higher performance than mixtures of pristine spiro-OMeTAD, spiro-OMeTAD, and FK209, and spiro-OMeTAD, Li-TFSI, and TBP. Such a synergistic effect between the Co-complex and Li-TFSI in conjunction with spiro-OMeTAD effectively improved the power conversion efficiency (PCE) of the fabricated solar cells. As a result, we achieved PCE of 10.4%, measured under standard solar conditions (AM 1.5G, 100 mW cm-2). © 2013 The Royal Society of Chemistry.

    A re-examination of cuticular components of Heliotropium filifolium allowed the isolation of four new compounds: 3'-hydroxy-2',2',6'-trimethyl-3H-spiro[1-benzo-furan-2,1'-cyclohexane]-5-carboxylic acid(2), methyl 3'-acetyloxy-2',2',6'-trimethyl-3H-spiro[1-benzofuran-2,1'-cyclohexane]-5-carboxylate (3), methyl 3'-isopentanoyloxy-2',2',6'-trimethyl-3H-spiro[1-benzofuran-2,1'-cyclohexane]-5-carboxylate (4) and methyl 3'-benzoyloxy-2',2',6'-trimethyl-3H-spiro[1-benzofuran-2,1'-cyclohexane]-5-carboxylate (5).Compounds 2-5 were identified by their spectroscopic analogies with filifolinol (1), and their structures confirmed by chemical correlation with 1. The antimicrobial properties of the compounds were tested against Gram positive and Gram negative bacteria. Some of them proved to be active against Gram positive, but inactive against Gram negative bacteria. In searching for structure-activity relationships from the obtained MIC values, lipophilicity was shown to be an important variable.

    NF-ĸB affects most aspects of cellular physiology. Deregulation of NF-ĸB signaling is associated with inflammatory diseases and cancer. In this study, we evaluated the cytotoxic and NF-ĸB inhibition potential of new spiro(lactone-cyclohexanone) compounds in two different human leukemia cell lines (U937 and K562). The anti-proliferative effects of the spiro(lactone-cyclohexanone) compounds on human K562 and U937 cell lines was evaluated by trypan blue staining, as well as their involvement in NF-kB regulation were analyzed by luciferase reporter gene assay, Caspase-3/7 activities were evaluated to analyze apoptosis induction. Both spiro(coumarin-cyclohexanone) 4 and spiro(6- methyllactone-cyclohexanone) 9 down-regulated cancer cell viability and proliferation. Compound 4 inhibited TNF-α-induced NF-ĸB activation in a dose-dependent manner and induced caspase-dependent apoptosis in both leukemia cell lines. Results show that compound 4 and compound 9 have potential as anti-cancer agents. In addition, compound 4 exerted NF-kB inhibition activity in leukemia cancer cells.

    2-(2-Alkoxycarbonyl-1-arylamino-1-propenyl)benzimidazolium and 5-(2-alkoxycarbonyl-1-arylamino-1-propenyl)triazolium salts were synthesized in good yields from the reaction of benzimidazole and triazole carbenes with ketenimines. Upon treatment with a base, both salts were converted into novel 1,3-dipoles which underwent [3+2] cycloaddition reactions with electron-deficient alkynes and allenes to produce benzimidazole-spiro-pyrroles or triazole-spiro-pyrroles. This work provides novel synthons for the construction of multifunctional spiro-pyrrole derivatives that are not easy accessible by other synthetic methods and are potentially amenable to further transformations.

    2016-06-08

    Thermally reduced graphene oxide (RGO) electrochemically activated by a quaternary alkyl ammonium-based organic electrolytes/activated carbon (AC) electrode asymmetric capacitor is proposed. The electrochemical activation process includes adsorption of anions into the pores of AC in the positive electrode and the interlayer intercalation of cations into RGO in the negative electrode under high potential (4.0 V). The EA process of RGO by quaternary alkyl ammonium was investigated by X-ray diffraction and electrochemical measurements, and the effects of cation size and structure were extensively evaluated. Intercalation by quaternary alkyl ammonium demonstrates a small degree of expansion of the whole crystal lattice (d002) and a large degree of expansion of the partial crystal lattice (d002) of RGO. RGO electrochemically activated by bis-spiro quaternary alkyl ammonium in propylene carbonate/AC asymmetric capacitor exhibits good activated efficiency, high specific capacity, and stable cyclability.

    2007-12-01

    Dr. Richard B. Dunn, astronomer emeritus at the National Solar Observatory, died of a heart attack on September 29, 2005. He was recognized as one of the foremost experimental solar physicists. His innovative designs for telescopes and instruments led to many important discoveries in solar physics. Born in Baltimore, Maryland, in 1927 and raised in Minneapolis, Minnesota, Dick's parents were Dr. Halbert L. Dunn and Katherine Brandner. Halbert (MD, Ph.D., F.A.P.H.A.) was an physician who became Chief of the National Office of Vital Statistics, Public Health Service. He published a paper "High Level Wellness for Man and Society" that became the founding paper of the field of wellness health care. After their divorce in 1942, Katherine moved to New York and became a social worker. Dick had two older brothers who died before him, Halbert (born in 1921, who became a civil engineer) and Robert (born in 1924, who became an architect). Dick earned a BS in mechanical engineering and an MS in astronomy at the University of Minnesota. At the end of World War II he served in the United States Army in Japan. For his master's degree, Dick undertook the design and construction of a Lyot-type birefringent filter for observations of solar prominences. This early work led to his acceptance at Harvard, where Professor Donald Menzel encouraged him to continue his work with the 15-inch Cambridge telescope. In 1951 he conducted part of his doctoral thesis work at the fledgling Sacramento Peak Observatory in southern New Mexico. The observatory director, Dr. John Evans, was impressed with Dick's outstanding instrumental talents and invited him to join as one of the first scientific staff members. During his first few years at Sac Peak, Dick developed two more birefringent filter systems including one with an integrated coronagraph. With this system, he produced the best prominence and spicule observations ever obtained. Dick's career was dedicated to obtaining solar observations of the

    Full Text Available Synthetic derivatives of spiro[pyrrolidinyl-3,3′-oxindole] alkaloids (coerulescine analogues were investigated as new ligands for aminergic G-protein coupled receptors (GPCRs. The chemical starting point 2′-phenylspiro[indoline-3,3′-pyrrolidin]-2-one scaffold was identified by virtual fragment screening utilizing ligand- and structure based methods. As a part of the hit-to-lead optimization a structure-activity relationship analysis was performed to explore the differently substituted 2′-phenyl-derivatives, introducing the phenylsulphonyl pharmacophore and examining the corresponding reduced spiro[pyrrolidine-3,3′-indoline] scaffold. The optimization process led to ligands with submicromolar affinities towards the 5-HT6 receptor that might serve as viable leads for further optimization.

    Highlights: • Soluble n-butyl substituted copper phthalocyanine. • Mixture with spiro-OMeTAD and employment in perovskite solar cells. • Impressive improvement of perovskite solar cell efficiency. • n-Butyl derivative gives better results than tert-butyl derivative - Abstract: Perovskite solar cells have been constructed under ambient conditions by using 2,2',7,7'-Tetrakis-(N,N-di-4-methoxyphenylamino)-9,9'-spirobifluorene (spiro-OMeTAD) mixed with a small quantity of soluble tetra-n-butyl substituted copper phthalocyanine as hole transporting material. The introduction of the phthalocyanine derivative resulted in an impressive increase of cell efficiency, which changed from 10.4% in the absence to 15.4% in the presence of phthalocyanine. This effect is related to the creation of deep traps in the hole transporting phase which block back-travelling electrons as well as to the improvement of the structural quality of the spiro-OMeTAD film in the presence of phthalocyanine. Both functionalities decrease shunt paths within the hole transporting phase resulting in increasing the fill factor and the open-circuit voltage of the cell.

  1. New regioselective multicomponent reaction: one pot synthesis of spiro heterobicyclic aliphatic rings.

    Byk, G; Gottlieb, H E; Herscovici, J; Mirkin, F

    2000-01-01

    In the context of our high-throughput organic synthesis program, we have studied the reactivity of special beta-keto esters toward the Biginelli reaction. We have found that a cyclic beta-keto ester reacts with one molecule of urea and two molecules of aldehyde to give a new family of spiro heterobicyclic aliphatic rings in good yields. Interestingly, the Biginelli product was not detected. After analysis of products using HPLC, 1H NMR, and 13C NMR, we have found that the reaction is driven by a regio-specific condensation of two molecules of aldehyde with the other reagents to afford only products harboring substituents exclusively in cis configuration. Monte Carlo minimization studies using MM2 force field suggest that cis products are energetically more stable than the trans counterparts. Together with previously reported data, these results suggest that the trans products were not obtained as result of steric hindrance produced by the equatorial position of one of the ring substituents. This new reaction is useful for high-throughput organic synthesis. Indeed, the new scaffold can be used to introduce additional groups in the molecules through remaining functional groups by a "domino strategy".

    An explosion on the Sun in 1859, serendipitously witnessed by amateur astronomer Richard Carrington, plunged telegraphic communications into chaos and bathed two thirds of the Earth's skies in aurorae. Explaining what happened to the Sun and how it could affect Earth, 93 million miles away, helped change the direction of astronomy. From being concerned principally with charting the stars to aid navigation, astronomers became increasingly concerned with what the celestial objects were, how they behaved and how they might affect life on Earth.

  9. Bridging the Knowledge Gaps between Richards' Equation and Budyko Equation

    Science.gov (United States)

    Wang, D.

    2017-12-01

    The empirical Budyko equation represents the partitioning of mean annual precipitation into evaporation and runoff. Richards' equation, based on Darcy's law, represents the movement of water in unsaturated soils. The linkage between Richards' equation and Budyko equation is presented by invoking the empirical Soil Conservation Service curve number (SCS-CN) model for computing surface runoff at the event-scale. The basis of the SCS-CN method is the proportionality relationship, i.e., the ratio of continuing abstraction to its potential is equal to the ratio of surface runoff to its potential value. The proportionality relationship can be derived from the Richards' equation for computing infiltration excess and saturation excess models at the catchment scale. Meanwhile, the generalized proportionality relationship is demonstrated as the common basis of SCS-CN method, monthly "abcd" model, and Budyko equation. Therefore, the linkage between Darcy's law and the emergent pattern of mean annual water balance at the catchment scale is presented through the proportionality relationship.

    Extracting charge-carrier mobilities for organic semiconductors from space-charge-limited conduction measurements is complicated in practice by nonideal factors such as trapping in defects and injection barriers. Here, we show that by allowing the bandlike charge-carrier mobility, trap characteristics, injection barrier heights, and the shunt resistance to vary in a multiple-trapping drift-diffusion model, a numerical fit can be obtained to the entire current density-voltage curve from experimental space-charge-limited current measurements on both symmetric and asymmetric 2 ,2',7 ,7' -tetrakis(N ,N -di-4-methoxyphenylamine)-9 ,9' -spirobifluorene (spiro-OMeTAD) single-carrier devices. This approach yields a bandlike mobility that is more than an order of magnitude higher than the effective mobility obtained using analytical approximations, such as the Mott-Gurney law and the moving-electrode equation. It is also shown that where these analytical approximations require a temperature-dependent effective mobility to achieve fits, the numerical model can yield a temperature-, electric-field-, and charge-carrier-density-independent mobility. Finally, we present an analytical model describing trap-limited current flow through a semiconductor in a symmetric single-carrier device. We compare the obtained charge-carrier mobility and trap characteristics from this analytical model to the results from the numerical model, showing excellent agreement. This work shows the importance of accounting for traps and injection barriers explicitly when analyzing current density-voltage curves from space-charge-limited current measurements.

    A series of novel fused-ring spiro compounds, spiro[benzo[ij]tetraphene-7,9'-fluorene] derivatives containing an end-capping aryl substituent at both the C3 and C10-positions has been designed and synthesized via multi-step Suzuki coupling reactions. 3-(1-Naphthyl)-10-phenyl, 3-(2-naphthyl)-10-phenyl and 3-[4-(1-naphthyl)phenyl]-10-phenyl showed improved glass transition temperatures (T{sub g}) with good thermal stability. Their photophysical, electrochemical, and electroluminescent properties were investigated and were used to construct blue organic light emission diodes (OLEDs). The typical OLED devices showed excellent performance; the based device exhibited highly efficient deep blue-light emission with a maximum efficiency of 5.27 cd/A (EQE, 4.63%) with CIE (x = 0.133, y = 0.144). According to these characteristics, these deep-blue light emitting materials have sufficient potential for fluorescent OLED applications.

    Richard Dawkins will speak on biology, Gerard ‘t Hooft will focus on physics, and Alain Connes will discuss mathematics. CERN scientists probe ever-deeper levels of matter and their interactions, but can we say that the patterns they see are truly fundamental? Does the universe obey the same laws throughout? Since mathematical constructions can be true in the absence of any relation to the physical world, is mathematics more fundamental than physics? Extraterrestrial life would probably look much different from that on Earth, but natural selection still be fundamental to their evolution?

    Full Text Available The concepto of the public sphere in Richard Rorty's philosophy, inherited of liberal tradition, allows be treated as a part of a game of language called democratic liberalism. One of the rules for validating a move in this game consists in taking for granted the distinction between the public and the private spheres. Richard Rorty thought that democratic liberalism did not need any foundation beyond the way to play it; its only criteria would be the game's practices, according an utopia which would allow us to make more movements in the game. That is, democratic liberalism does not require foundations, but just practices for achieving a social hioe inspired on freedom and pluralism. This kind of utopia, based upon the non-cruelty principle, would make possible an inclusive society where everyone would have a place for their own private vocabulary. In this way, Rorty would have linked freedom and solidarity. However, this language-game reveals the paradox of the link which implies the meaning of the public shere. Herein, freedom is not a sufficient condition of solidarity; hence, there is no place for social inclusion in Rorty's language game.

  4. Argument from Design in Richard Baxter's Natural Theology

    Full Text Available The article deals with the teleological argument, or argument from design, as expounded by a famous English Protestant theologian Richard Baxter, one of the leading 17-th century English Puritans, in his work “The Reasons of the Christian Religion”. Natural theology, providing arguments for the existence of God based on reason and without appeal to the Revelation, has always played a vital role throughout the entire history of theological thought. The most popular was the so called teleological argument, or the argument from design, which stands out among all rational arguments for the existence of the Creator. It is mostly known from the “Fifth Way” of the medieval Scholastic philosopher Thomas Aquinas and a famous work “Natural Theology” by an English 19-th century theologian William Paley. The foundation for the modern research in the area was laid during the age of the Scientific Revolution of the 17th century English nature philosophers and theologians, especially Robert Boyle, who believed the teleological argument to be the key element of Natural Theology. His friend and confessor, Richard Baxter, a prominent representative of the Puritan Natural Theology, mostly known by his theological works, paved the way for Natural Theology both in his own time and the following centuries. His work was thought to be the best collection of the evidences for Christianity.

    Directory of Open Access Journals (Sweden)

    Robert L. Miller

    2006-03-01

    Full Text Available Handling Qualitative Data: A Practical Guide is an introductory textbook covering all stages of qualitative research from the initial conceptualisation of a project, through data collection and analysis, to writing up. The author, Lyn RICHARDS, is a well-known developer of two key qualitative software analysis packages, NUD*IST and NVivo. While RICHARDS clearly advocates the use of qualitative analysis software, the text is "generic" and could be used in tandem with any qualitative software package. The book concentrates on practical advice about the use of software to manage and analyse qualitative data, and provides insights in these areas. The consideration of issues around team-based qualitative research is another strong point. However, due in part to its short length, the overall coverage of topics tends to be superficial. In itself, the book does not provide sufficient detailed support for a student who would like to use it as her/his main source of guidance for carrying out a qualitative research project.

    Full Text Available http://dx.doi.org/10.5007/1677-2954.2009v8n2p247 Em um artigo de 1966, Amartya Sen procurou mostrar que mesmo Richard Hare, um devoto explícitodo antinaturalismo em ética, ainda que inadvertidamente, incorreu num tipo de naturalismo que Senintitulou de existencial. Neste breve artigo, traço um resumo dessa crítica à teoria de Hare, em especial,da chamada “Lei de Hume”, a qual Sen preferiu apropriadamente intitular “Regra de Hare”. Pretendomostrar como esse tipo peculiar de “existencialismo” nos conduz, ainda que sob o possível protesto deHare e seus seguidores, a conclusões subjetivistas e relativistas sobre a moralidade.

    2015-07-01

    Full Text Available A cultura musical romântica encontra em Richard Wagner– em sua obra musical e teórica – um de seus maiores protagonistas.A rejeição da Aufklärung e a exaltação da supremacia germânica –elementos constituidores da Weltanschauung romântica alemã –caracterizam fortemente o pensamento e a atitude de Wagner frenteà vida, assumindo conotações ainda mais radicais através de seucontumaz antissemitismo. De modo que pensar Wagner por ocasiãode seu bicentenário também significa retomar uma discussão crucialsobre o romantismo alemão e suas implicações políticas eideológicas.

    2015-07-01

    The review presents a historical excursion into catalytic alkene metathesis, covering the problems of history of the discovery of this process, as well as investigations on the properties, structure and reactivity of the most popular ruthenium catalysts for metathesis, mechanism of their action and decomposition. The main part covers studies devoted to the syntheses of bridged azabicyclic and 1-azaspirocyclic compounds comprising the intramolecular metathesis of dienes as the key step. The formation of a bicyclic skeleton of a series of natural bridged (cocaine, ferruginine, calystegines, and anatoxin-a) and spiro (pinnaic acids, halichlorine, hystrionicotoxin, and cephalotaxine) azabicycles, as well as their analogues and compounds with larger rings is demonstrated. The methods for the synthesis of diene precursors and the conditions for final assembling of the bicyclic compounds are considered in detail. The generalization of the literature data allows one to efficiently carry out the mentioned process taking into account the most important features. The bibliography includes 129 references.

  11. Nano-ZnO Catalyzed Multicomponent One-Pot Synthesis of Novel Spiro(indoline-pyranodioxine Derivatives

    2014-01-01

    Full Text Available A simple catalytic protocol for the synthesis of novel spiro[indoline-pyranodioxine] derivatives has been developed using ZnO nanoparticle as an efficient, green, and reusable catalyst. The derivatives are obtained in moderate to excellent yield by one-pot three-component reaction of an isatin, malononitrile/ethylcyanoacetate, and 2,2-dimethyl-1,3-dioxane-4,6-dione in absolute ethanol under conventional heating and microwave irradiation. The catalyst was recovered by filtration from the reaction mixture and reused during five consecutive runs without any apparent loss of activity for the same reaction. The mild reaction conditions and recyclability of the catalyst make it environmentally benign synthetic procedure.

  12. Relationship between Antimalarial Activity and Heme Alkylation for Spiro- and Dispiro-1,2,4-Trioxolane Antimalarials▿

    The reaction of spiro- and dispiro-1,2,4-trioxolane antimalarials with heme has been investigated to provide further insight into the mechanism of action for this important class of antimalarials. A series of trioxolanes with various antimalarial potencies was found to be unreactive in the presence of Fe(III) hemin, but all were rapidly degraded by reduced Fe(II) heme. The major reaction product from the heme-mediated degradation of biologically active trioxolanes was an alkylated heme adduct resulting from addition of a radical intermediate. Under standardized reaction conditions, a correlation (R2 = 0.88) was found between the extent of heme alkylation and in vitro antimalarial activity, suggesting that heme alkylation may be related to the mechanism of action for these trioxolanes. Significantly less heme alkylation was observed for the clinically utilized artemisinin derivatives compared to the equipotent trioxolanes included in this study. PMID:18268087

  14. New iridium complex as additive to the spiro-OMeTAD in perovskite solar cells with enhanced stability

    Full Text Available A new iridium complex, IrCp*Cl(PyPyz[TFSI], has been synthesized and used as additive for the hole transporter material, spiro-OMeTAD, in perovskite solar cells. The cells prepared with this Ir additive present higher efficiency than reference cells, and similar to cells prepared with Co additive. We have determined that the presence of metal complexes as additives decreases the recombination rate, as it has been observed by impedance spectroscopy. Very interestingly, while the efficiency after 3 months decreases by 22% and 70% for reference cell and cell with Co additive, respectively, the efficiency of devices containing the Ir additive is only decreased by a 4%.

  15. La paradoja de lo público en Richard Rorty

    Martha Palacio Avendaño

    2008-01-01

    Full Text Available El concepto de lo público en Richard Rorty, heredero de la tradición liberal, admite ser tratado como parte de un juego del lenguaje denominado liberalismo democrático. En ese sentido, una de las reglas de este juego para saber si una jugada es válida consiste en asumir la distinción entre esfera pública y privada. Richard Rorty pensó que este juego no requería fundamentación más allá de la forma de jugarlo, que el criterio en que se apoyaría estaba en las prácticas que tienen lugar dentro del mismo con arreglo a sostener una utopía que permitiera hacer cada vez más jugadas. Esto es, el liberalismo democrático no requería basarse en algo más allá de las prácticas conducentes a lograr una esperanza social alentada por la libertad en defensa del pluralismo. Su utopía liberal, guiada por el principio de la no-crueldad, haría posible una sociedad inclusiva en la que todos tuvieran espacio para su léxico privado. De este modo, Rorty habría vinculado libertad y solidaridad, pero su juego del lenguaje permite advertir la paradoja del vínculo que implicaría el sentido de lo público. Aquí, la libertad no es condición suficiente de la solidaridad, de modo que la inclusión social no tiene cabida en su juego del lenguaje.

    A thermally induced, substrate-dependent reaction of alkynyl diazo compounds has been developed. This transformation produces spiro-4H-pyrazole-oxindoles and fused 1H-pyrazoles in good to high yields from the corresponding alpha-cyano and alpha-sulfonyl diazo compounds. The salient features of this reaction include excellent chemoselectivity and atom-economy, mild reaction conditions, simple purification and potential for large scale production.

The antimicrobial properties of the compounds were tested against Gram positive and Gram negative bacteria. Some of them proved to be active against Gram positive, but inactive against Gram negative bacteria. In searching for structure-activity relationships from the obtained MIC values, lipophilicity was shown to be an important variable.

  5. Transcendence, Taxis, Trust: Richard Kearney and Jacques Derrida

    Directory of Open Access Journals (Sweden)

    Ulrich Schmiedel

    2017-03-01

    Full Text Available Whatever else it takes to drive a taxi, it takes trust. Day after day, the driver has to decide whether the other is or is not trustworthy. I take the taxi as a test case to analyze and assess Richard Kearney’s diacritical hermeneutics of the other. I argue that Kearney functionalizes the concept of transcendence in order to connect the transcendence of the finite other to the transcendence of the infinite other. However, in his central critique of the deconstructionists following Jacques Derrida, Kearney counters his connection. While Kearney’s critique of Derrida’s account of absolute alterity is correct and compelling, I argue that Derrida’s critique of a distinction between the trustworthy other and the non-trustworthy other might be more crucial than Kearney contends. Insisting on openness to the other’s otherness, Derrida provokes any hermeneutic of the other to trust in transcendence. The taxi is taken as a test to illustrate the implications which diacritical and deconstructive drivers might have for evaluating the entanglement of ethics and eschatology—inside and outside the taxi.

  6. Forjando nuestras democracias: entre Richard Rorty y Vladimiro Montesinos

    Directory of Open Access Journals (Sweden)

    2001-07-01

    Full Text Available This article aims at explaining the recent history of Peru, in an exercise in which it is possible to extract lessons about the way Latin American democracies have been(or have not been forged. The text draws a parallel between the ideas developed by Richard Rorty in his recently published book, Forjar nuestro país. El pensamiento de izquierdas en los Estados Unidos del siglo XX, and the events in Fugimori's and Montesinos' Peru. If, according to what Rorty believes, "national pride is for the countries what self esteem is for individuals ... " how would it be possible to narrate a history in which there are few motives to be proud of? Trying to escape fatalism and sarcasm, the text tries to show that Montesino's political course is, symbolically, a summary of the decomposition process of Peruvian democracy. Secondly, the text analyses the movements of the political left wing and deals with the support the regimen received from inside and outside the country, a support that was largely based on the illusion of political stability. Finally, it states, as Rorty does, that in order to forge democracies it is necessary for us to be deeply committed to the defense of the State of Right.

    2010-02-01

    Full Text Available Le roman de Richard Powers, Operation Wandering Soul (1993, présente le lien subtil qui associe un mondialisme déjà usé et vieillissant à l’enfant perçu comme catégorie dominante. Comme les faces serpentines d’un ruban de Möbius lové autour de l’illimité et de l’intemporel, le texte, tendu entre ses deux infinis – l’univers et l’enfant – révise la portée, la conception, la structure et le style du genre romanesque. Délaissant Aristote pour Einstein, Operation Wandering Soul se place sur le terrain de la cosmologie. Le récit, qui rassemble la kyrielle des grands ralliements juvéniles et leurs vains pèlerinages, concentre l’espace-temps dans une présentation qui évoque la « somme des histoires » de Richard Feynman. La contraction de l’espace-temps opérée par le roman ne fait pas de celui-ci un hymne simpliste au global (catégorie déjà aussi datée que celle des malheureux vétérans du Vietnam, mais capte au contraire la conscience grandissante d’une existence sans origine qui s’étend à perte de vue au-delà de ses coordonnées supposées. Le roman s’enroule sur lui-même tout en s’épanchant au dehors, boucle ses cadres et ses détours tout en desserrant leur emprise. Il fait tourner la roue de ses récits comme des planètes en rotation, la ronde d’un système solaire, le tourbillon d’une galaxie. La conscience que présente Operation Wandering Soul ne se résume donc pas au seul point de vue de l’âme errante qu’est le personnage de Kraft, mais consiste en la somme de tous les temps et de tous les lieux, de leurs strates accumulées comme une conscience en acte, complexe et tissée de réseaux, qui n’appartient à personne et est partagée par tous. Cette accumulation organise le jeu des perspectives multiples qui instaurent l’acte de lecture et sont instaurées par lui. À cet égard, lire constitue ici une physique des oubliés.Richard Powers’ novel Operation Wandering

  8. PolyRES: A polygon-based Richards equation solver

    International Nuclear Information System (INIS)

    Hills, R.G.

    1995-12-01

    This document describes the theory, implementation, and use of a software package designed to solve the transient, two-dimensional, Richards equation for water flow in unsaturated-saturated soils. This package was specifically designed to model complex geometries with minimal input from the user and to simulate groundwater flow related to assessment of low-level radioactive waste disposal sites and engineered facilities. The spatial variation of the hydraulic properties can be defined across individual polygon-shaped subdomains, called objects. These objects combine to form a polygon-shaped model domain. Each object can have its own distribution of hydraulic parameters. The resulting model domain and polygon-shaped internal objects are mapped onto a rectangular, finite-volume, computational grid by a preprocessor. This allows the user to specify model geometry independently of the underlying grid and greatly simplifies user input for complex geometries. In addition, this approach significantly reduces the computational requirements since complex geometries are actually modeled on a rectangular grid. This results in well-structured, finite difference-like systems of equations that require minimal storage and are very efficient to solve. The documentation for this software package includes a user's manual, a detailed description of the underlying theory, and a detailed discussion of program flow. Several example problems are presented that show the use and features of the software package. The water flow predictions for several of these example problems are compared to those of another algorithm to test for prediction equivalency

    The Jewish historian and theorist of medicine, Richard Koch, teaching in Frankfurt/Main, fled in 1936 from National Socialist Germany to the USSR where he lived in the Caucasian spa Essentuki until his death in 1949. Here he worked as a doctor and continued his scientific work, especially on the foundations of medicine in natural philosophy. None of his works of this time were published. Koch was a scientific outsider in the USSR, and he was aware of this. However, he tried to make his views compatible with official doctrines. In 1947 he lost his employment at the medical clinic of Essentuki, and his material situation grew worse. It is still an open question whether this development was related to an increasingly anti-Jewish atmosphere in the USSR that was linked with the Stalinist "purges", as Koch himself appeared to believe. Before his flight from Germany Koch did not show any tendency towards communism or the political left at all. His attitude towards Soviet society and Stalin was mixed: cautious criticism was accompanied by strong expressions of commitment to Stalin and Koch's new Socialist home. The question to what extent Koch's comments showed his true convictions must remain without a definite answer. At least in part they can be understood as precautions in threatening circumstances. The opportunity of a remigration to Germany after 1945, however, was turned down by Koch.

  10. Perception of Leitmotives in Richard Wagner's Der Ring des Nibelungen

    Directory of Open Access Journals (Sweden)

    David J. Baker

    2017-05-01

    Full Text Available The music of Richard Wagner tends to generate very diverse judgments indicative of the complex relationship between listeners and the sophisticated musical structures in Wagner's music. This paper presents findings from two listening experiments using the music from Wagner's Der Ring des Nibelungen that explores musical as well as individual listener parameters to better understand how listeners are able to hear leitmotives, a compositional device closely associated with Wagner's music. Results confirm findings from a previous experiment showing that specific expertise with Wagner's music can account for a greater portion of the variance in an individual's ability to recognize and remember musical material compared to measures of generic musical training. Results also explore how acoustical distance of the leitmotives affects memory recognition using a chroma similarity measure. In addition, we show how characteristics of the compositional structure of the leitmotives contributes to their salience and memorability. A final model is then presented that accounts for the aforementioned individual differences factors, as well as parameters of musical surface and structure. Our results suggest that that future work in music perception may consider both individual differences variables beyond musical training, as well as symbolic features and audio commonly used in music information retrieval in order to build robust models of musical perception and cognition.

    In this paper, the pore filling of spiro-MeOTAD (2,2\\',7,7\\'-tetrakis-(N,N-di-p-methoxyphenylamine)9, 9\\'-spirobifluorene) in mesoporous TiO2 films is quantified for the first time using XPS depth profiling and UVVis absorption spectroscopy. We show that spiro-OMeTAD can penetrate the entire depth of the film, and its concentration is constant throughout the film. We determine that in a 2.5-•m-thick film, the volume of the pores is 60-65% filled. The pores become less filled when thicker films are used. Such filling fraction is much higher than the solution concentration because the excess solution on top of the film can act as a reservoir during the spin coating process. Lastly, we demonstrate that by using a lower spin coating speed and higher spiro-OMeTAD solution concentration, we can increase the filling fraction and consequently the efficiency of the device

    2014-01-08

    The reaction of antimony and selenium in the bromine-rich Lewis acidic ionic liquid [BMIm]Br·4.7AlBr3 (BMIm: 1-butyl-3- methylimidazolium) in the presence of a small amount of NbCl5 at 160 °C yielded dark-red crystals of [Sb7Se8Br 2][AlX4]3. For X = Cl0.15(1)Br 0.85(1), the compound is isostructural to [Sb7S 8Br2][AlCl4]3 [P212 121, a = 12.5132(5) Å, b = 17.7394(6) Å, c = 18.3013(6) Å]. For a higher chlorine content, X = Cl 0.58(1)Br0.42(1), a slightly disordered variant with a bisected unit cell is found [P21212, a = 12.3757(3) Å, b = 17.4116(5) Å, c = 9.0420(2) Å]. The [Sb 7Se8Br2]3+ heteropolycation (C 2 symmetry) is a spiro double-cubane with an antimony atom on the shared corner. From this distorted octahedrally coordinated central atom, tricoordinate selenium and antimony atoms alternate in the bonding sequence. The terminal antimony atoms each bind to a bromine atom. Quantum chemical calculations confirm polar covalent Sb-Se bonding within the cubes and indicate three-center, four-electron bonds for the six-coordinate spiro atoms. The calculated charge distribution reflects the electron-donor role of the antimony atoms. The use of a chlorine-rich ionic liquid resulted in the formation of triclinic [Sb13Se16Br2][AlX4] 5 with X = Cl0.80(1)Br0.20(1) [P$\\\\bar {1}$, a = 9.0842(5) Å, b = 19.607(1) Å, c = 21.511(1) Å, α = 64.116(6), β = 79.768(7), γ = 88.499(7)]. The cationic cluster [Sb13Se16Br2]5+ is a bromine-terminated spiro quadruple-cubane. This 31 atom concatenation of four cubes is assumed to be the largest known discrete main group polycation. A similar reaction in a chloride-free system yielded [Sb7Se 8Br2][Sb13Se16Br2] [AlBr4]8. In its monoclinic structure [P2/c, a = 27.214(5) Å, b = 9.383(2) Å, c = 22.917(4) Å, β = 101.68(1)], the two types of polycations alternate in layers along the a axis. In the series [Sb4+3nSe4+4nBr2](2+n)+, these cations are the members with n = 1 and 3. Copyright © 2014 WILEY-VCH Verlag GmbH & Co. KGa

    Full Text Available Lung function measures are heritable traits that predict population morbidity and mortality and are essential for the diagnosis of chronic obstructive pulmonary disease (COPD. Variations in many genes have been reported to affect these traits, but attempts at replication have provided conflicting results. Recently, we undertook a meta-analysis of Genome Wide Association Study (GWAS results for lung function measures in 20,288 individuals from the general population (the SpiroMeta consortium.To comprehensively analyse previously reported genetic associations with lung function measures, and to investigate whether single nucleotide polymorphisms (SNPs in these genomic regions are associated with lung function in a large population sample.We analysed association for SNPs tagging 130 genes and 48 intergenic regions (+/-10 kb, after conducting a systematic review of the literature in the PubMed database for genetic association studies reporting lung function associations.The analysis included 16,936 genotyped and imputed SNPs. No loci showed overall significant association for FEV(1 or FEV(1/FVC traits using a carefully defined significance threshold of 1.3×10(-5. The most significant loci associated with FEV(1 include SNPs tagging MACROD2 (P = 6.81×10(-5, CNTN5 (P = 4.37×10(-4, and TRPV4 (P = 1.58×10(-3. Among ever-smokers, SERPINA1 showed the most significant association with FEV(1 (P = 8.41×10(-5, followed by PDE4D (P = 1.22×10(-4. The strongest association with FEV(1/FVC ratio was observed with ABCC1 (P = 4.38×10(-4, and ESR1 (P = 5.42×10(-4 among ever-smokers.Polymorphisms spanning previously associated lung function genes did not show strong evidence for association with lung function measures in the SpiroMeta consortium population. Common SERPINA1 polymorphisms may affect FEV(1 among smokers in the general population.

    Full Text Available The paper looks at Shakespeare’s historical play Richard III and its fairy tale-like character given by the configuration of the main character as an arch-villain and the presence of motifs and patterns typically associated with the fairy tale genre. More specifically, it considers the mother-son relationship between the Duchess of York and Richard in the light of the motif of monstrous birth. It is not a coincidence that the emergence of such motifs coincides with the historical contexts of the early modern period. Reading Richard III in this key is related to the revisionist approach to chronicle plays.

    Full Text Available The objective of this study was to introduce application of the Richards equation on modelling and prediction of stand diameter distribution. The long-term repeated measurement data sets, consisted of 309 diameter frequency distributions from Chinese fir (Cunninghamia lanceolata plantations in the southern China, were used. Also, 150 stands were used as fitting data, the other 159 stands were used for testing. Nonlinear regression method (NRM or maximum likelihood estimates method (MLEM were applied to estimate the parameters of models, and the parameter prediction method (PPM and parameter recovery method (PRM were used to predict the diameter distributions of unknown stands. Four main conclusions were obtained: (1 R distribution presented a more accurate simulation than three-parametric Weibull function; (2 the parameters p, q and r of R distribution proved to be its scale, location and shape parameters, and have a deep relationship with stand characteristics, which means the parameters of R distribution have good theoretical interpretation; (3 the ordinate of inflection point of R distribution has significant relativity with its skewness and kurtosis, and the fitted main distribution range for the cumulative diameter distribution of Chinese fir plantations was 0.4∼0.6; (4 the goodness-of-fit test showed diameter distributions of unknown stands can be well estimated by applying R distribution based on PRM or the combination of PPM and PRM under the condition that only quadratic mean DBH or plus stand age are known, and the non-rejection rates were near 80%, which are higher than the 72.33% non-rejection rate of three-parametric Weibull function based on the combination of PPM and PRM.

    It is with a great deal of both happiness and sadness that I have to announce that we are losing one of the real strengths of the Journal of Physics: Condensed Matter (JPCM). Dr Richard Palmer, our Senior Publisher, announced his retirement, and this issue marks the first without his involvement. Of course, we are happy that he will get to enjoy his retirement, but we are sad to lose such a valuable member of our team. Richard first started work at IOP Publishing in March 1971 as an Editorial Assistant with Journal of Physics B: Atomic and Molecular Physics. After a few months, he transferred to Journal of Physics C: Solid State Physics. During his first year, he was sent on a residential publishing training course and asked to sign an undertaking to stay at IOP Publishing for at least two years. Although Richard refused to sign, as he did not want to commit himself, he has remained with the journal since then. The following year, the Assistant Editor of Journal of Physics C: Solid State Physics, Malcolm Haines, walked out without notice in order to work on his family vineyard in France, and Richard stepped into the breach. In those days, external editors had a much more hands-on role in IOP Publishing and he had to travel to Harwell to be interviewed by Alan Lidiard, the Honorary Editor of Journal of Physics C: Solid State Physics, before being given the job of Assistant Editor permanently. I am told that in those days the job consisted mainly of editing and proofreading and peer review. There was no journal development work. At some point in the early 1980s, production and peer review were split into separate departments and Richard then headed a group of journals consisting of Journal of Physics C: Solid State Physics, Journal of Physics D: Applied Physics and Journal of Physics F: Metal Physics, Semiconductor Science and Technology, Superconductor Science and Technology, Plasma Physics and Controlled Fusion, and later Nanotechnology and Modelling and Simulation

    Solution-processable polyimides of intrinsic microporosity (PIM-PIs) comprising relatively inflexible and contorted backbones have demonstrated outstanding molecular-sieving behavior in membrane-based separation of gas/gas pairs. In this work, the effects of systematically increasing intra-chain rigidity on the propylene/propane separation properties were compared for PIM-PIs made from 2,3,5,6-tetramethyl-1,4-phenylene diamine (TMPD) and (i) spiro-centered dianhyride (SPDA-TMPD or PIM-PI-1) and (ii) 9,10-diisopropyltriptycene-based dianhydride (TPDA-TMPD or KAUST PI-1). Pure-gas experiments at 2 bar and 35 oC showed significant increases in C3H6 permeability and C3H6/C3H8 selectivity by transitioning from PIM-PI-1 (P(C3H6)=393 Barrer, α(C3H6/C3H8)=6) to KAUST-PI-1 (P(C3H6)=817 Barrer, α(C3H6/C3H8)=16), positioning KAUST-PI-1 considerably above the experimentally observed pure-gas C3H6/C3H8 polymer upper bound. However, 50:50 C3H6/C3H8 mixed-gas feeds induced significant losses in C3H6 permeability and C3H6/C3H8 selectivity relative to the 2 bar pure-gas data for PIM-PI-1 and KAUST-PI-1 as the C3H6/C3H8 selectivity dropped from 6 to 3 and 16 to 5, respectively, at 2 bar C3H6 partial pressure due to plasticization and competitive sorption.

  6. Anomalous regioselective four-member multicomponent Biginelli reaction II: one-pot parallel synthesis of spiro heterobicyclic aliphatic rings.

    Byk, Gerardo; Kabha, Eihab

    2004-01-01

    In a previous preliminary study, we found that a cyclic five-member ring beta-keto ester (lactone) reacts with one molecule of urea and two of aldehyde to give a new family of spiro heterobicyclic aliphatic rings in good yields with no traces of the expected dihydropyrimidine (Biginelli) products. The reaction is driven by a regiospecific condensation of two molecules of aldehyde with urea and beta-keto-gamma-lactone to afford only products harboring substitutions exclusively in a syn configuration (Byk, G.; Gottlieb, H. E.; Herscovici, J.; Mirkin, F. J. Comb. Chem. 2000, 2, 732-735). In the present work ((a) Presented in part at ISCT Combitech, October 15, 2002, Israel, and Eurocombi-2, Copenhagen 2003 (oral and poster presentation). (b) Also in American Peptide Society Symposium, Boston, 2003 (poster presentation). (c) Abstract in Biopolymers 2003, 71 (3), 354-355), we report a large and exciting extension of this new reaction utilizing parallel organic synthesis arrays, as demonstrated by the use of chiral beta-keto-gamma-lactams, derived from natural amino acids, instead of tetronic acid (beta-keto-gamma-lactone) and the potential of the spirobicyclic products for generating "libraries from libraries". Interestingly, we note an unusual and important anisotropy effect induced by perpendicular interactions between rigid pi systems and different groups placed at the alpha position of the obtained spirobicyclic system. Stereo/regioselectivity of the aldehyde condensation is driven by the nature of the substitutions on the starting beta-keto-gamma-lactam. Aromatic aldehydes can be used as starting reagents with good yields; however, when aliphatic aldehydes are used, the desired products are obtained in poor yields, as observed in the classical Biginelli reaction. The possible reasons for these poor yields are addressed and clarify, to some extent, the complexity of the Biginelli multicomponent reaction mechanism and, in particular, the mechanism of the present

    Increasing challenge arising from configurational interconversion in aqueous solvent renders it rather difficult to isolate high-purity tautomeric reference standards and thus largely hinders the holistic quality control of traditional Chinese medicine (TCM). Spiro oxindole alkaloids (SOAs), as the markers for the medicinal Uncaria herbs, can easily isomerize in polar or aqueous solvent via a retro-Mannich reaction. In the present study, supercritical fluid chromatography (SFC) is utilized to separate and isolate two pairs of 7-epimeric SOAs, including rhynchophylline (R) and isorhynchophylline (IR), corynoxine (C) and corynoxine B (CB), from Uncaria macrophylla. Initially, the solvent that can stabilize SOA epimers was systematically screened, and acetonitrile was used to dissolve and as the modifier in SFC. Then, key parameters of ultra-high performance SFC (ultra-performance convergence chromatography, UPC 2 ), comprising stationary phase, additive in modifier, column temperature, ABPR pressure, and flow rate, were optimized in sequence. Two isocratic UPC 2 methods were developed on the achiral Torus 1-AA and Torus Diol columns, suitable for UV and MS detection, respectively. MCI gel column chromatography fractionated the U. macrophylla extract into two mixtures (R/IR and C/CB). Preparative SFC, using a Viridis Prep Silica 2-EP OBD column and acetonitrile-0.2% diethylamine in CO 2 as the mobile phase, was finally employed for compound purification. As a result, the purity of four SOA compounds was all higher than 95%. Different from reversed-phase HPLC, SFC, by use of water-free mobile phase (inert CO 2 and aprotic modifier), provides a solution to rapid analysis and isolation of tautomeric reference standards for quality control of TCM.

    A copper-catalyzed difunctionalizing trifluoromethylation of activated alkynes with the cheap reagent sodium trifluoromethanesulfinate (NaSO2CF3 or Langlois' reagent) has been developed incorporating a tandem cyclization/dearomatization process. This strategy affords a straightforward route to synthesis of 3-(trifluoromethyl)-spiro[4.5]trienones, and presents an example of difunctionalization of alkynes for simultaneous formation of two carbon-carbon single bonds and one carbon-oxygen double bond. © 2015 WILEY-VCH Verlag GmbH & Co.

    Herrlin, K.; Stroemberg, T.; Lidgren, L.; Walloee, A.; Pettersson, H.

    Four hundred and thirty trochanteric factures operated upon with McLaughlin, Ender or Richard's osteosynthesis were divided into 6 different types based on their radiographic appearance before and immediately after reposition with special reference to the medial cortical support. A significant correlation was found between the fracture type and subsequent mechanical complications where types 1 and 2 gave less, and types 4 and 5 more complications. A comparison of the various osteosyntheses showed that Richard's had significantly fewer complications than either the Ender or McLaughlin types. For Richard's osteosynthesis alone no correlation to fracture type could be made because of the small number of complications in this group.

    A novel electron acceptor, namely 2,2′-(12H,12′H-10,10′-spirobi[indeno[2,1-b]fluorene]-12,12′-diylidene)dimalononitrile (4CN-spiro), exhibiting a three-dimensional molecular structure was synthesized and its thermal, photophysical, electrochemical, crystal, and photovoltaic properties were investigated. The novel acceptor exhibits excellent thermal stability with a decomposition temperature of 460 °C, an absorption extending to 600 nm, and a LUMO level of −3.63 eV. Solution processed bulk-heterojunction (BHJ) organic solar cells were fabricated using 4CN-spiro as an acceptor and polythieno[3,4-b]-thiophene-co-benzodithiophene (PTB7) as a donor polymer. The effect of the donor-to-acceptor ratio and processing conditions on the device performance was investigated. A device processed from tetrachloroethane with a donor to acceptor weight ratio of 1 : 1 yielded a power conversion efficiency (PCE) of 0.80%.

The TiO{sub 2} nanotube (TNT) array electrode was compared with a mesoporous one in terms of loading with an organic dye of high extinction coefficient. It was shown that it is possible to build a working solid state dye sensitized solar cell device with such a combination of materials and its performance was compared with a device in which the solid state HTM was replaced by a liquid state electrolyte.

    Strain-induced piezoelectric potential (piezopotential) within wurtzite-structured ZnO can engineer the energy-band structure at a contact or a junction and, thus, enhance the performance of corresponding optoelectronic devices by effectively tuning the charge carriers' separation and transport. Here, we report the fabrication of a flexible self-powered ZnO/Spiro-MeOTAD hybrid heterojunction ultraviolet photodetector (UV PD). The obtained device has a fast and stable response to the UV light illumination at zero bias. Together with responsivity and detectivity, the photocurrent can be increased about 1-fold upon applying a 0.753% tensile strain. The enhanced performance can be attributed to more efficient separation and transport of photogenerated electron-hole pairs, which is favored by the positive piezopotential modulated energy-band structure at the ZnO-Spiro-MeOTAD interface. This study demonstrates a promising approach to optimize the performance of a photodetector made of piezoelectric semiconductor materials through straining.

  7. Fluid flow in porous media using image-based modelling to parametrize Richards' equation.

    The parameters in Richards' equation are usually calculated from experimentally measured values of the soil-water characteristic curve and saturated hydraulic conductivity. The complex pore structures that often occur in porous media complicate such parametrization due to hysteresis between wetting and drying and the effects of tortuosity. Rather than estimate the parameters in Richards' equation from these indirect measurements, image-based modelling is used to investigate the relationship between the pore structure and the parameters. A three-dimensional, X-ray computed tomography image stack of a soil sample with voxel resolution of 6 μm has been used to create a computational mesh. The Cahn-Hilliard-Stokes equations for two-fluid flow, in this case water and air, were applied to this mesh and solved using the finite-element method in COMSOL Multiphysics. The upscaled parameters in Richards' equation are then obtained via homogenization. The effect on the soil-water retention curve due to three different contact angles, 0°, 20° and 60°, was also investigated. The results show that the pore structure affects the properties of the flow on the large scale, and different contact angles can change the parameters for Richards' equation.

    The Phare project CZ 632.02.04 'Realization of closure of a chamber in the Richard repository as input for establishing a safety case' is a follow up implementation phase of the Phare project, CZ 01.14.03 'Solution for closure of a chamber in the Richard repository'. Main objective of both projects is to propose and realize a disposal system in selected chambers of the Richard repository, which will eliminate burden from the past practices in waste management during the first phase of the Richard repository operation (1965 - 1980) and which will improve its overall long term safety. This objective will be assured by realization of the concept of so called 'hydraulic cage', which technical solution was developed by DBE Technology within the Phare project CZ 01.14.03. The solution is described in the previous presentation 'Hydraulic Cage Concept for Waste Chambers and its Technical Implementation for the Underground Richard Repository, Litomerice, Czech Republic'.

    Weisberg, Michael; Wood, Rega

    2003-05-01

    Richard Rufus of Cornwall offered a novel solution to the problem of mixture raised by Aristotle. The puzzle is that mixts or mixed bodies (blood, flesh, wood, etc.) seem to be unexplainable through logic, even though the world is full of them. Rufus's contribution to this long-standing theoretical debate is the development of a modal interpretation of certain Averroistic doctrines. Rufus's account, which posits that the elemental forms in a mixt are in accidental potential, avoids many of the problems that plagued non-atomistic medieval theories of mixture. This paper is an initial examination of Rufus' account.

  9. Leachate flow around a well in MSW landfill: Analysis of field tests using Richards model.

    2017-05-01

    During the lifespan of a Municipal Solid Waste landfill, its leachate drainage system may get clogged. Then, as a consequence of rainfall, leachate generation and possibly leachate injection, the moisture content in the landfill increases to the point that a leachate mound could be created. Therefore, pumping the leachate becomes a necessary solution. This paper presents an original analysis of leachate pumping and injection in an instrumented well. The water table level around the well is monitored by nine piezometers which allow the leachate flow behaviour to be captured. A numerical model based on Richards equation and an exponential relationship between saturated hydraulic conductivity and depth is used to analyze the landfill response to pumping and injection. Decreasing permeability with depth appears to have a major influence on the behaviour of the leachate flow. It could have a drastic negative impact on the pumping efficiency with a maximum quasi-stationary pumping rate limited to approximately 1m 3 /h for the tested well and the radius of influence is less than 20m. The numerical model provides a reasonable description of both pumping and injection tests. However, an anomalous behaviour observed at the transition between pumping and recovery phases is observed. This could be due to a limitation of the Richards model in that it neglects the gas phase behaviour and other double porosity heterogeneous effects. Copyright © 2016 Elsevier Ltd.

  10. Wooing-Scenes in “Richard III”: A Parody of Courtliness?

    Directory of Open Access Journals (Sweden)

    Agnieszka Stępkowska

    2009-11-01

    Full Text Available In the famous opening soliloquy of Shakespeare’s Richard III, Richard mightily voices his repugnance to “fair well-spoken days” and their “idle pleasures”. He realizes his physical deformity and believes that it sets him apart from others. He openly admits that he is “not shaped for sportive tricks, nor made to court an amorous looking-glass”. Yet, his monstrosity constitutes more perhaps of his aggressive masculine exceptionality rather than of his deformity. Richard’s bullying masculinity manifests itself in his contempt for women. In the wooing scenes we clearly see his pugnacious pursuit of power over effeminate contentment by reducing women to mere objects. Additionally, those scenes are interesting from a psychological viewpoint as they brim over with conflicting emotions. Therefore, the paper explores two wooing encounters of the play, which belong the best examples of effective persuasion and also something we may refer to as ‘the power of eloquence’.

    In order to study the slurry diffusion law during grouting, Richards unsaturated-saturated model was introduced, the definition of the grouting model is clear, the Richards model control equation was established, And the BP neural network was introduced, the improved fluid-solid coupling model was constructed, Through the use of saturated - unsaturated seepage flow model, As well as the overflow boundary iterative solution of the mixed boundary conditions, the free surface is calculated. Engineering practice for an example, with the aid of multi - field coupling analysis software, the diffusion law of slurry was simulated numerically. The results show that the slurry diffusion rule is affected by grouting material, initial pressure and other factors. When the slurry starts, it flows in the cracks along the upper side of the grouting hole, when the pressure gradient is reduced to the critical pressure, that is, to the lower side of the flow, when the slurry diffusion stability, and ultimately its shape like an 8. The slurry is spread evenly from the overall point of view, from the grouting mouth toward the surrounding evenly spread, it gradually reaches saturation by non-saturation, and it is not a purely saturated flow, when the slurry spread and reach a saturated state, the diffusion time is the engineering grouting time.

  12. Gamma radiation and radon concentration levels at the radioactive waste repositories 'Richard' and 'Bratrstvi'

    Berka, Z.; Sabol, J.; Janu, M.

    1998-01-01

    Owing to the fact that cosmic rays are shielded off, the photon equivalent dose rates in the corridors of the Richard repository are usually slightly lower than outside. However, in points close to barrels containing radioactive waste, the dose rates can reach values as high as tens of μSv/h. Because of high concentrations of natural radionuclides, the dose rates in the Bratrstvi repository is generally considerably higher, as much as 5 times the normal background value. Radon concentrations exhibit specific time variations which are modified by ventilation. Where ventilation is poor or absent, the radon concentrations are extremely high, viz. up to 30 and 300 kBq/m 3 in the Richard and Bratrstvi repositories, respectively. Personal exposure of workers depend on the total time spent underground and on the ventilation rate. While the contribution from photons can be kept below the relevant limits, the radon-related doses may be significant and even exceed the professional limits if no precautions are taken. (P.A.)

  13. The 1D Richards' equation in two layered soils: a Filippov approach to treat discontinuities

    Science.gov (United States)

    Berardi, Marco; Difonzo, Fabio; Vurro, Michele; Lopez, Luciano

    2018-05-01

    The infiltration process into the soil is generally modeled by the Richards' partial differential equation (PDE). In this paper a new approach for modeling the infiltration process through the interface of two different soils is proposed, where the interface is seen as a discontinuity surface defined by suitable state variables. Thus, the original 1D Richards' PDE, enriched by a particular choice of the boundary conditions, is first approximated by means of a time semidiscretization, that is by means of the transversal method of lines (TMOL). In such a way a sequence of discontinuous initial value problems, described by a sequence of second order differential systems in the space variable, is derived. Then, Filippov theory on discontinuous dynamical systems may be applied in order to study the relevant dynamics of the problem. The numerical integration of the semidiscretized differential system will be performed by using a one-step method, which employs an event driven procedure to locate the discontinuity surface and to adequately change the vector field.

    In the middle of the 20th century David Bohm and Richard Feynman developed two fundamentally different approaches of modern quantum mechanics: Bohm a realistic interpretation by means of hidden parameters and Feynman the path-integral formalism. This is by this more remarakable, because both physicists started from similar conditions and originated from similar connections. By its comparing approach this study presents more than a contribution to the history of the quantum theory. By the question for the social and cultural conditions of the formation of theories it is furthermore of science-sociological and science-theoretical interest. The in the beginning similar and later different binding of both scientists into the scientific community allows furthermore to study, which adapting pressure each group puts on the individual scientist and the fundamental parts of his research, and which new degrees of freedom in the formation of theories arise, when this constraint is cancelled.

    Richard Arwed Pfeifer (1877-1957) was one of the initiators and foster fathers of the renowned child-psychiatric and special needs education workgroup at Leipzig University under Paul Schröder (1873-1941) in the 1920s and 1930s. This paper is an account of their dispute concerning the interrelations between child and adolescent psychiatry and special needs education, as well as their disagreement about whether adolescent psychopaths should be admitted to specialized child psychiatric wards or elsewhere. Moreover, Pfeifer questioned the practical relevance of the separation of constitutional and environmentally-based psychopathy and fought eugenic research, which he found incompatible with the ethics of his profession as a remedial teacher and child psychiatrist.

  19. A critical review of Richard Lynn's reports on reaction time and race.

    Science.gov (United States)

    Thomas, Drew M

    2011-01-01

    In the early 1990s, psychologist Richard Lynn published papers documenting average reaction times and decision times in samples of nine-year-olds taken from across the world. After summarizing these data, Lynn interpreted his results as evidence of national and racial differences in decision time and general intelligence. Others have also interpreted Lynn's data as evidence of racial differences in decision time and intelligence. However, comparing Lynn's summaries with his original reports shows that Lynn misreported and omitted some of his own data. Once these errors are fixed the rankings of nations in Lynn's datasets are unstable across different decision time measures. This instability, as well as within-race heterogeneity and between-race overlap in decision times, implies that Lynn's reaction time data do not permit generalizations about the decision times and intelligence of people of different races.

  20. Analytical and grid-free solutions to the Lighthill-Whitham-Richards traffic flow model

    KAUST Repository

    Mazaré , Pierre Emmanuel; Dehwah, Ahmad H.; Claudel, Christian G.; Bayen, Alexandre M.

    2011-01-01

    In this article, we propose a computational method for solving the Lighthill-Whitham-Richards (LWR) partial differential equation (PDE) semi-analytically for arbitrary piecewise-constant initial and boundary conditions, and for arbitrary concave fundamental diagrams. With these assumptions, we show that the solution to the LWR PDE at any location and time can be computed exactly and semi-analytically for a very low computational cost using the cumulative number of vehicles formulation of the problem. We implement the proposed computational method on a representative traffic flow scenario to illustrate the exactness of the analytical solution. We also show that the proposed scheme can handle more complex scenarios including traffic lights or moving bottlenecks. The computational cost of the method is very favorable, and is compared with existing algorithms. A toolbox implementation available for public download is briefly described, and posted at http://traffic.berkeley.edu/project/downloads/lwrsolver. © 2011 Elsevier Ltd.

  2. Analytical and grid-free solutions to the Lighthill-Whitham-Richards traffic flow model

    KAUST Repository

    Mazaré, Pierre Emmanuel

    2011-12-01

    In this article, we propose a computational method for solving the Lighthill-Whitham-Richards (LWR) partial differential equation (PDE) semi-analytically for arbitrary piecewise-constant initial and boundary conditions, and for arbitrary concave fundamental diagrams. With these assumptions, we show that the solution to the LWR PDE at any location and time can be computed exactly and semi-analytically for a very low computational cost using the cumulative number of vehicles formulation of the problem. We implement the proposed computational method on a representative traffic flow scenario to illustrate the exactness of the analytical solution. We also show that the proposed scheme can handle more complex scenarios including traffic lights or moving bottlenecks. The computational cost of the method is very favorable, and is compared with existing algorithms. A toolbox implementation available for public download is briefly described, and posted at http://traffic.berkeley.edu/project/downloads/lwrsolver. © 2011 Elsevier Ltd.

    Full Text Available In this timely book Richard Peet and his team lay the foundation with an excellent analysis of the process of globalisation and the resultant emergence of the global economy. The authors are especially critical of the increasing influence of institutions like the International Monetary Fund (IMF, World Bank and World Trade Organisation (WTO on the economy and the consequences experienced by peoples, cultures and the environment. The single ideology of neo-liberalism is blamed for the undesirable outcomes. This book considers concepts of power, political interest, hegemony, discourse, responsibility and the power of practicality, in critically examining the IMF, World Bank and WTO. The conclusion is reached that “all three institutions play roles greatly different from those originally agreed to under the charters that set them up”.

    2017-01-01

    This essay provides a fresh account of the break between Oswald Külpe and his master Wilhelm Wundt. Kurt Danziger's reconstruction of the "repudiation" of Wundt, which has become the canon for this significant episode of history of psychology, focused on the supposed influence of Ernst Mach on this set of events, overshadowing the other exponent of Empiriocriticism: Richard Avenarius. Analyzing archival documents and examining anew the primary sources, the paper shows that Avenarius was himself a member of Wundt's circle, and that his "repudiation" of the master paved the way for Külpe. The essay points out the original anti-Wundtian aspects of Avenarius' notion of psychology, thus showing how they were then adopted by Külpe. © 2016 Wiley Periodicals, Inc.

    Full Text Available Cet article interprète Gain, sixième roman de Richard Powers, à la lumière du concept de « seconde modernité » proposé par le sociologue allemand Ulrich Beck. Ce concept souligne la dissémination du risque et la manière dont celle-ci invalide les marchés conclus par la « première modernité » entre l’avenir et le présent, entre l’intérieur du corps et l’extérieur. Cet article entend montrer que Beck fournit un cadre interprétatif utile à la compréhension de ces rapports, hors des impasses catégorielles que suscite l’opposition entre les deux régimes narratifs à l’œuvre dans le texte : le récit biographique, local et individuel, de la maladie de Laura Rowen Bodey, et l’histoire collective de l’entreprise Clare devenue conglomérat.This essay interprets Richard Powers' sixth novel Gain with reference to the German sociologist Ulrich Beck's concept of “second modernity.” The concept underscores the dispersal of risk and how it shreds promissory notes understood in “first modernity” between the future and present and the insides and outsides of the body. It argues that Beck supplies an apt interpretive framework for understanding these relationships and overcoming the categorical impasses between the two narrative words at work in Power's novel, the biographical situatedness of Laura Rowen Bodey's illness and the corporate history of the Clare conglomerate.

  8. Newtonian nudging for a Richards equation-based distributed hydrological model

    Science.gov (United States)

    Paniconi, Claudio; Marrocu, Marino; Putti, Mario; Verbunt, Mark

    The objective of data assimilation is to provide physically consistent estimates of spatially distributed environmental variables. In this study a relatively simple data assimilation method has been implemented in a relatively complex hydrological model. The data assimilation technique is Newtonian relaxation or nudging, in which model variables are driven towards observations by a forcing term added to the model equations. The forcing term is proportional to the difference between simulation and observation (relaxation component) and contains four-dimensional weighting functions that can incorporate prior knowledge about the spatial and temporal variability and characteristic scales of the state variable(s) being assimilated. The numerical model couples a three-dimensional finite element Richards equation solver for variably saturated porous media and a finite difference diffusion wave approximation based on digital elevation data for surface water dynamics. We describe the implementation of the data assimilation algorithm for the coupled model and report on the numerical and hydrological performance of the resulting assimilation scheme. Nudging is shown to be successful in improving the hydrological simulation results, and it introduces little computational cost, in terms of CPU and other numerical aspects of the model's behavior, in some cases even improving numerical performance compared to model runs without nudging. We also examine the sensitivity of the model to nudging term parameters including the spatio-temporal influence coefficients in the weighting functions. Overall the nudging algorithm is quite flexible, for instance in dealing with concurrent observation datasets, gridded or scattered data, and different state variables, and the implementation presented here can be readily extended to any of these features not already incorporated. Moreover the nudging code and tests can serve as a basis for implementation of more sophisticated data assimilation

    We demonstrate a simple and fast post-deposition treatment with high process compatibility on the hole transport material (HTM) Spiro-MeOTAD in vapor-assisted solution processed methylammonium lead triiodide (CH3NH3PbI3)-based solar cells.The prepared Co-doped p-type Spiro-MeOTAD films are treated by O3 at room temperature for 5 min,10 min,and 20 min,respectively,prior to the deposition of the metal electrodes.Compared with the traditional oxidation of Spiro-MeOTAD films overnight in dry air,our fast O3 treatment of HTM at room temperature only needs just 10 min,and a relative 40.3% increment in the power conversion efficiency is observed with respect to the result of without-treated perovskite solar cells.This improvement of efficiency is mainly attributed to the obvious increase of the fill factor and short-circuit current density,despite a slight decrease in the open-circuit voltage.Ultraviolet photoelectron spectroscopy (UPS) and Hall effect measurement method are employed in our study to determine the changes of properties after O3 treatment in HTM.It is found that after the HTM is exposed to O3,its p-type doping level is enhanced.The enhancement of conductivity and Hall mobility of the film,resulting from the improvement in p-doping level of HTM,leads to better performances of perovskite solar cells.Best power conversion efficiencies (PCEs) of 13.05% and 16.39% are achieved with most properly optimized HTM via CH3NH3I vapor-assisted method and traditional single-step method respectively.

O texto de Annette surpreende pela maneira inédita pela qual analisa as obras do arquiteto, por sua compreensão da cultura brasileira, o que acaba por ampliar o alcance dessa abordagem. O caminho escolhido para efetuar sua análise é a partir dos componentes constitutivos da obra arquitetônica: terreno, cobertura, balanços, pilotis, e constrói um raciocínio sobre a articulação desses elementos no espaço. E assim - apoiada, sobretudo, nos textos do autor inglês Colin Rowe - analisa os projetos sob a ótica da tradição clássica e sua ordenação espacial. Contudo, a autora não se restringe aos aspectos formais ou materiais dos edifícios: concreto aparente, rigor estrutural, apreço pela técnica, características que levariam a uma associação imediata, e talvez superficial, com estilos tais como brutalista, minimalista ou abstracionista. E, sim, explora a relação entre componentes fundamentais de cada projeto: planos horizontais e verticais, a relação com o terreno, a oposição entre cheios e vazios e a luz como elemento constitutivo do espaço.

    2009-11-01

    This year marks the 20th anniversary of the launch of Journal of Physics: Condensed Matter in 1989. The journal was formed from the merger of Journal of Physics C: Solid State Physics and Journal of Physics F: Metal Physics which had separated in 1971. In the 20 years since its launch, Journal of Physics: Condensed Matter has more than doubled in size, while raising standards. Indeed, Journal of Physics: Condensed Matter has become one of the leading scientific journals for our field. This could not have occurred without great leadership at the top. No one has been more responsible for this growth in both size and quality than our Senior Publisher, Richard Palmer. Richard first started work at IOP in March 1971 as an Editorial Assistant with J. Phys. B After a few months, he transferred to J. Phys.C The following year, the Assistant Editor of J. Phys. C, Malcolm Haines, left suddenly in order to work on his family vineyard in France, and Richard stepped into the breach. In those days, external editors had a much more hands-on role in IOP Publishing and he had to travel to Harwell to be interviewed by Alan Lidiard, the Honorary Editor of J. Phys. C, before being given the job of Assistant Editor permanently. Since J. Phys. C and J. Phys. F re-merged to form Journal of Physics: Condensed Matter, Richard gradually shed his other journal responsibilities, except for Reports on Progress in Physics, to build up Journal of Physics: Condensed Matter. He has worked closely with four Editors-in-Chief of J. Phys. C and five of Journal of Physics: Condensed Matter. When Richard announced his retirement this past winter, we met it with a great deal of both happiness and sadness. Of course, we are happy that he is going to be allowed to enjoy his retirement, but we remain very sad to lose such a valuable member of our team, especially the one who had provided the heart and soul of the journal over its 20 years. We will be able to rely upon the team which Richard ably trained as

    Full Text Available In this work we study the problem of modeling identification of a population employing a discrete dynamic model based on the Richards growth model. The population is subjected to interventions due to consumption, such as hunting or farming animals. The model identification allows us to estimate the probability or the average time for a population number to reach a certain level. The parameter inference for these models are obtained with the use of the likelihood profile technique as developed in this paper. The identification method here developed can be applied to evaluate the productivity of animal husbandry or to evaluate the risk of extinction of autochthon populations. It is applied to data of the Brazilian beef cattle herd population, and the the population number to reach a certain goal level is investigated.Neste trabalho estudamos o problema de identificação do modelo de uma população utilizando um modelo dinâmico discreto baseado no modelo de crescimento de Richards. A população é submetida a intervenções devido ao consumo, como no caso de caça ou na criação de animais. A identificação do modelo permite-nos estimar a probabilidade ou o tempo médio de ocorrência para que se atinja um certo número populacional. A inferência paramétrica dos modelos é obtida através da técnica de perfil de máxima verossimilhança como desenvolvida neste trabalho. O método de identificação desenvolvido pode ser aplicado para avaliar a produtividade de criação animal ou o risco de extinção de uma população autóctone. Ele foi aplicado aos dados da população global de gado de corte bovino brasileiro, e é utilizado na investigação de a população atingir um certo número desejado de cabeças.

  1. Who invented the dichotomous key? Richard Waller's watercolors of the herbs of Britain.

    Science.gov (United States)

    Griffing, Lawrence R

    2011-12-01

    On 27 March 1689, Richard Waller, Fellow and Secretary of the Royal Society presented his "Tables of the English Herbs reduced to such an order, as to find the name of them by their external figures and shapes" to his assembled colleagues at a meeting of the Royal Society. These tables were developed for the novice by being color images, composed in pencil and watercolor, of selected plants and their distinguishing characteristics. The botanical watercolors for the tables are now a Turning-the-Pages document online on the website of the Royal Society. However, for the past 320 years, the scientific context for the creation of these outstanding botanical watercolors has remained obscure. These tables were developed by Waller as an image-based dichotomous key, pre-dating by almost 100 years the text-based dichotomous keys in the first edition of Flora Française (1778) by Jean Baptiste Lamarck, who is generally given priority for the development of the dichotomous key. How these large folio images were arranged to illustrate a dichotomous key is unknown, but an arrangement based on Waller's description is illustrated here as leaf-ordering for the separate hierarchical clusters (tables). Although only 24 species of watercolored dicot herbs out of a total of 65 in the set of watercolors (the others being monocots) are used in these tables, they are a "proof of concept", serving as models upon which a method is based, that of using a key composed of dichotomous choices for aiding identification.

    2011-12-01

    Full Text Available This essay contextualizes the work of war correspondent Richard Harding Davis within an evolving “imperial news apparatus” that would culminate in his reporting of the Spanish-American War. Critics have conventionally framed Davis squarely within the imperial cause, associating him with his admirer Roosevelt and naval admiral Alfred T. Mahan. Contrary to readings of Davis as an apologist for US imperialism, Trivedi contends that Davis understood how US imperial power relied on an information apparatus to communicate to an increasingly media-conscious American public through culture, that is, via familiar narratives, symbols, and objects—what Trivedi calls “imperial news.” The essay follows Davis’s development from his fictional representation of the new war correspondent in “The Reporter Who Made Himself King” to his own war correspondence before and after the Spanish-American War as collected in the memoirs A Year from a Reporter’s Notebook (1897, Cuba in War Time (1897, and Notes of a War Correspondent (1912. Davis’s war correspondence and fictional work effectively stage US imperialism as “unincorporated power”: that is, as power reliant on a developing news-making apparatus that deploys particular discursive strategies to validate its political claims. This staging critiques strategies of US imperial sovereignty—specifically its “privatization of knowledge” and its promotion of the war correspondent as nothing more than a spectator and purveyor of massacres.

  5. Against the Nihilism of Suffering and Death: Richard E. K. Kim and His Works

    Jooyeon Rhee

    2016-03-01

    Full Text Available This article examines the life and works of Richard E. K. Kim (1932–2009, a first-generation Korean diasporic writer in the United States. It focuses on how Kim struggled to overcome the nihilism of suffering and death that derived from colonialism and the Korean War through his literary works. Kim witnessed firsthand these two major historical events, which caused irrevocable psychological and physical damage to many people of his generation. In his autobiographical fiction, he conveys painful memories of the events by reviving the voices of people in that era. What his works offer us goes beyond vivid memories of the past, however; they also present the power of forgiveness as a condition to overcome the nihilism of suffering and death. Remembrance and forgiveness are, therefore, two major thematic pillars of his works that enable us to connect to these difficult and traumatic times. These themes are portrayed in such a gripping way mainly because Kim tried to maintain a certain distance—an emotional and linguistic distance—from the familiar, in order to elucidate the reality of the human condition: an ontological position of the exile from which he produced his works. This article argues that Kim’s works provide us the possibility to transcend the nihilism of historical trauma through articulating the meaning of remembrance and forgiveness from his self-assumed position of exile.

  6. Providing the physical basis of SCS curve number method and its proportionality relationship from Richards' equation

    Hooshyar, M.; Wang, D.

    2016-12-01

    The empirical proportionality relationship, which indicates that the ratio of cumulative surface runoff and infiltration to their corresponding potentials are equal, is the basis of the extensively used Soil Conservation Service Curve Number (SCS-CN) method. The objective of this paper is to provide the physical basis of the SCS-CN method and its proportionality hypothesis from the infiltration excess runoff generation perspective. To achieve this purpose, an analytical solution of Richards' equation is derived for ponded infiltration in shallow water table environment under the following boundary conditions: 1) the soil is saturated at the land surface; and 2) there is a no-flux boundary which moves downward. The solution is established based on the assumptions of negligible gravitational effect, constant soil water diffusivity, and hydrostatic soil moisture profile between the no-flux boundary and water table. Based on the derived analytical solution, the proportionality hypothesis is a reasonable approximation for rainfall partitioning at the early stage of ponded infiltration in areas with a shallow water table for coarse textured soils.

  7. Unreliability and the Animal Narrator in Richard Adams’s The Plague Dogs

    Directory of Open Access Journals (Sweden)

    Anja Höing

    2017-03-01

    Full Text Available Richard Adams’s talking animal story The Plague Dogs (1978, with its deeply genre-atypical mode of narration, offers a multiplicity of avenues to explore the literary animal as animal. The story draws much of its power from the psychological complexity and related unreliability of both canine narrators, two research lab escapees gone feral. Both the terrier Snitter and the black mongrel Rowf are mentally ill and experience a highly subjective, part-fantastic world. In episodes of zero focalization, a sarcastic voice comments on the plot from the off, aggressively attacking a thoroughly anthropocentric superstructure the protagonists themselves are oblivious of, and presenting all that is normally constructed as “rational” in the implied reader’s world as a carnivalesque farce. Combining these equally unreliable narratives, The Plague Dogs creates a unique mixture of what Phelan (2007 calls “estranging” and “bonding” unreliability and brings to light the devastating consequences of anthropocentrism. The Plague Dogs not only defamiliarizes a genre usually committed to conventional means of storytelling, but the dominant Western conception of the status of animals in the world, showing that once we start to read the animal as animal, this sets into motion an avalanche of other concepts in need of re-reading, among them the very ones making up the fundamental pillars of Western societies’ anthropocentric self-conception.

  8. Perbandingan antara Etika Jürgen Habermas dan Richard Rorty sebagai Prinsip Dasar Bertindak Manusia

    2010-10-01

    Full Text Available Ethics without doubt is an issue in every scientific field. Questions on ethics are not merely questions on the responsibility of one or two specific individuals, but rather as what have been defined accurately by Immanuel Kant in Critique of Practical Reason – as question of all humanity as a thinking creature and the freedom of choice on, “what should I do”. From Kant’s definition, we may infer that if human can not think and not free in determining their choice, it would be almost impossible to hope for moral responsibility. However this article does not mean to give a full and historical description on ethics, but a sketch on discourse of contemporary ethics which is represented by two famous philosophers, Jürgen Habermas from the tradition of  Critical Theory from Frankfurt School, dan Richard Rorty with “Neo-Pragmatism”. Habermas proposes “discourse ethics” while Rorty proposes ethic concepts through his “liberal-ironists”. It is hoped that the assembly of readers may gain an insight of the unavoidable ethics problems since every ethical position must be theory laden and the theory itself has historical characteristics (the characteristics, origin and historical context of the schools behind it. Therefore ethics is a neverending reflection although it has been started from 2500 years ago. Ethics invites us from specific sciences to enter its general discourse which unavoidably all-encompassing in its nature. 

  9. Richard Rorty:From Anti-metaphysical Neo-Pragmatism to Rejection of Philosophy

    Directory of Open Access Journals (Sweden)

    2010-01-01

    Full Text Available Richard Rorty is a neo-Pragmatist philosopher. For three decades, he has attacked the traditional philosophy (from Plato to Kant as well as any other epistemology searching for truth or claiming to mirror the nature in his philosophical works. Rorty holds that, according to the history of philosophy in his reading, there is no final answer to the traditional questions concerning knowledge, truth, and representation. These questions, therefore, should be dissolved and denied. He maintains that knowledge is justified belief, justification, however, being not the consequence of some correspondence between the theory or the statement, but the consequence of conversation, social practice, group consensus, and social solidarity. Rorty also thinks that democracy has priority on philosophy, disagreeing with the thesis that philosophy is the foundation of the rest of culture.Despite of usefulness of some elements and implications of Rorty’s metaphilosophy (such as his emphasis on freedom, democracy, and pluralism as well as his insisting on philosophical humility and avoiding scientific pride, it is faced with several problems, including 1 ignoring the referential and realist features of language, 2 confusing interpretation and reality, 3 eliminating the border between objectivity and subjectivity, 4 interfering of public and private life, and 5 ignoring the need of science, culture, technology and, in particular, politics, in philosophy. The authors try to show and analyze some elements of these problems.

  10. Has David Howden Vindicated Richard von Mises’s Definition of Probability?

    Mark R. Crovelli

    2009-11-01

    Full Text Available In my recent article on these pages (Crovelli 2009 I argued that members of the Austrian School of economics have adopted and defended a faulty definition of probability. I argued that the definition of probability necessarily depends upon the nature of the world in which we live. I claimed that if the nature of the world is such that every event and phenomenon which occurs has a cause of some sort, then probability must be defined subjectively; that is, “as a measure of our uncertainty about the likelihood of occurrence of some event or phenomenon, based upon evidence that need not derive solely from past frequencies of ‘collectives’ or ‘classes.’” I further claimed that the nature of the world is indeed such that all events and phenomena have prior causes, and that this fact compels us to adopt a subjective definition of probability.David Howden has recently published what he claims is a refutation of my argument in his article “Single Trial Probability Applications: Can Subjectivity Evade Frequency Limitations” (Howden 2009. Unfortunately, Mr. Howden appears to not have understood my argument, and his purported refutation of my subjective definition consequently amounts to nothing more than a concatenation of confused and fallacious ideas that are completely irrelevant to my argument. David Howden has thus failed in his attempt to vindicate Richard von Mises’s definition of probability.

  11. Blood, politics, and social science. Richard Titmuss and the Institute of Economic Affairs, 1957-1973.

    2002-09-01

    Long before his last book, The Gift Relationship: From Human Blood to Social Policy, was published in early 1971, Richard M. Titmuss (1907-1973), a professor of social administration at the London School of Economics, had been a major figure in the debates over the welfare state. The Gift Relationship was the culmination of an eventful relationship with the Institute of Economic Affairs, a think tank that advocated the extension of rational pricing to social services. By arguing that the British system of blood procurement and distribution, based on free giving within the National Health Service, was more efficient than the partly commercialized American system, Titmuss intended to signal the dangers of the increasing commercialization of society. What made for the impact of his book, however, was not merely its argument that transfusion-transmitted infections were much more common with paid than with voluntary donors, but also its reflections on what it is that holds a society together. And here Titmuss argued that a "socialist" social policy, by encouraging the sense of community, played a central role. The eclecticism of Titmuss's work, together with its strong ethical and political flavor, makes it a rich and original account of the "social" at a time when heated debated over social policy, both in Britain and in the United States, raised the question of the division of labor among the social sciences.

  12. First record of the Asian diaptomid Neodiaptomus schmackeri (Poppe & Richard, 1892 (Crustacea: Copepoda: Calanoida in Europe

    Full Text Available Albania, as well as a great part of the Balkan area in general, still suffers a lack of environmental studies especially in limnological research. The Dumre plateau, in Central Albania, is characterized by an extraordinary high number of karst lakes in a small geographic area. Despite their environmental peculiarity, very few biological data are to date available for these lakes, none on the zooplankton. For this reason, 15 water bodies located in the central area of the plateau were selected for a preliminary limnological survey carried out in the years 2008-2011. Neodiaptomus schmackeri (Poppe & Richard, 1892, a diaptomid calanoid copepod characterized by a South-Eastern Palearctic - Oriental distribution, and the most widely spread Neodiaptomus species in Asia, was found in 8 lakes of the Dumre area. This finding represents the first record of the species, and of the entire genus Neodiaptomus, for Europe. Several environmental variables were measured to characterize the lakes, and the co-occurring planktonic crustaceans were also identified. Taxonomical drawings and descriptions of the main morphological features of both sexes are herein provided in order to compare the Albanian populations of N. schmackeri with those of the native distribution area of the species. The possible causes which determined the occurrence of this non-indigenous species in several Dumre lakes are discussed.

    2016-11-01

    Full Text Available This study assessed the radiological health hazards to various body organs of workers working within Transnet Precinct in Richards Bay in Kwazulu-Natal, South Africa due to radionuclide content of mineral ores often stored within the facility. Thirty samples were collected from five mineral ores (rock phosphate, rutile, zircon, coal and hematite and analyzed for 238U, 234U, 226Ra, 210Pb, 235U, 232Th, 228Ra, 228Th and 40K using delayed neutron activation analysis and low energy gamma spectroscopy. Rutile was found to be the most radioactive mineral ore within the facility with 210Pb concentration of 759.00 ± 106.00 Bq·kg−1. Effective annual dose rate in (mSv·y−1 delivered to different organs of the body: testes, bone marrow, whole body, lungs and ovaries from mineral ores were such that dose from mineral ores decreased in the order coal > rutile > rock phosphate > hematite > zircon. The organs with the highest received dose rate were the testes and this received dose was from coal. However, all of the calculated absorbed dose rates to organs of the body were below the maximum permissible safety limits.

  14. “This World Is Not My Home”: Richard Mouw and Christian Nationalism

    Directory of Open Access Journals (Sweden)

    2016-12-01

    Full Text Available American evangelicalism has often been punctuated by dual commitments to the United States and to God. Those commitments were strongest within politically conservative evangelicalism. Though representing a solid majority among professing evangelicals, conservatives could not speak for the movement as a whole. Politically progressive evangelicals, beginning in the 1960s, formed a dissenting opinion of the post-World War II revival of Christian nationalism. They dared to challenge American action abroad, noticeably during the Vietnam War. Their critique of Christian nationalism and conservative evangelicals’ close ties to the Republican Party led them to seek refuge in either progressive policies or the Democratic Party. A third, underexplored subgroup of evangelicalism rooted in reformed theology becomes important to consider in this regard. These reformed evangelicals sought to contextualize nationalism in biblical rather than partisan or political terms. This goal is championed well by Richard Mouw, resulting in a nuanced look at evangelical Christians’ difficult dual role as both citizens of the Kingdom of God and the United States.

  15. Poets/Trump/Philosophers: Reflections on Richard Rorty’s Liberalism, Ten Years after His Death

    Directory of Open Access Journals (Sweden)

    Giorgio Baruchello

    2017-08-01

    Full Text Available Starting with a prescient 1998 quote on the impending decline of US liberal democracy into right-wing, strong-man-based demagogy, this paper outlines Richard Rorty’s political philosophy, which I believe can help us understand perplexing political trends in today’s political reality well beyond the US alone. Specifically, I tackle three key-terms encapsulating the thrust of Rorty’s political philosophy, i.e. “liberalism of fear”, “bourgeois” and “postmodernism”. Also, I address a contraposition that explains how Rorty would approach and attempt to defend liberal democracy from contemporary right-wing, strong-man-based degenerations, namely the priority of “poetry” over “philosophy”. Essentially, if one wishes to win in the political arena, she must be armed with the most effective rhetorical weaponry, however good, solid and well-argued her political views may be. Finally, some remarks are offered on the role that “philosophy” can still play within the same arena.

  16. Arctic observers: Richard King, monogenism and the historicisation of Inuit through travel narratives.

    Sera-Shriar, Efram

    2015-06-01

    In 1848 the ethnologist, surgeon and Arctic explorer Richard King (1810-1876) published a three-part series on Inuit in the Journal of the Ethnological Society of London. This series provided a detailed history of Inuit from the eleventh century to the early nineteenth century. It incorporated a mixture of King's personal observations from his experience travelling to the Arctic as a member of George Back's expedition (1833-1835), and the testimonies of other contemporary and historical actors who had written on the subject. The aim was to historicise Inuit through the use of travel reports and show persistent features among the race. King was a monogenist and his sensitive recasting of Inuit was influenced by his participation in a research community actively engaged in humanitarian and abolitionist causes. The physician and ethnologist Thomas Hodgkin (1798-1866) argued that King's research on Inuit was one of the best ethnological approaches to emulate and that it set the standard for the nascent discipline. If we are to take seriously Hodgkin's claim, we should look at how King constructed his depiction of Inuit. There is much to be gained by investigating the practices of nineteenth-century ethnologists because it strengthens our knowledge of the discipline's past and shows how modern understandings of races were formed.

  20. Sufi, Christian or Buddhist? Richard Francis Burton’s “Parameters of Belief”

    Directory of Open Access Journals (Sweden)

    John Wallen

    2013-09-01

    Full Text Available Richard Burton has been interpreted and misinterpreted by literary critics as eminent as Edward Said and Louisa Pratt as well as by others such as Rana Kabbani and Reina Lewis. Biographers like Fawn Brody, Edward Rice, Mary Lovell and Jon Godsall have also had their say. Burton has been variously described as imperialist, sexist, gay, obssessed with pornography, racist, plagiarist, sexual libertine, scatologist, expert sociologist, profoundly deceitful and impotent. In spite of this negative press, interest in Burton is always high as his life and times are relevant to many scholars interested in the 19th century origins of modern thought and postcolonial ideas. In this paper presentation I will attempt to get beyond the confused and contradictory portrayals of Burton over the last 50 or so years by looking in some detail at Burton’s two long poems: Stone Talk and The Kasidah. In these works, published 15 years apart, Burton writes under pseudonyms and, as I will argue, is able to express many of his deepest beliefs, especially in The Kasidah where he is playing the part of Hadji Abu Al Yezid, a Sufi like-wise man who possesses some startling similarities to Burton himself. What emerges from this close examination of the texts is a sensitive relativist who, while adhering to the scientific method in all his practical dealings, is yet able to consider the possibility that everything we see around us and all our experience of the world might be, finally, nothing more than Maya and illusion.

  1. The Effect of Richard Wagner's Music and Beliefs on Hitler's Ideology

    2016-09-01

    Full Text Available The Holocaust will always be remembered as one of the most horrific and evil events in all of history. One question that has been so pervasive in regards to this historical event is the question of why. Why exactly did Hitler massacre the Jewish people? Why did he come to the conclusion that the Jews were somehow lesser than him, and that it was okay to kill them? What and who were his influences and how did they help form Hitler’s opinions leading up to the Holocaust? Although more than one situation or person influenced Hitler, I believe that one man in particular really helped contribute to Hitler’s ideas, especially about the Jewish people. This man is the famous musician Richard Wagner. While musicologists admit that Wagner was a musical genius, one aspect of his career that is hard to ignore is his strong antisemitism. In addition to speaking about his hatred for the Jews, he also wrote about it in his music, making it hard to glance over. Hitler had been close to the Wagner family, and had an obsessive, cult-like infatuation with Wagner’s music beginning in his childhood. This infatuation with Wagner’s music and his closeness to his later family helped facilitate and solidify his negative views about the Jewish people. In this paper I will explore the antisemitism that is within Wagner’s music and writing, and then I will discuss how Wagner’s antisemitism helped inform, influence, and shape Hitler’s ideas, indirectly assisting in the propagation of the Holocaust.

    Full Text Available Body sway while maintaining an upright quiet stance reflects an active process of balance based on the integration of visual, vestibular, somatosensory and proprioceptive inputs. Richard Serra’s Promenade sculpture featured in the 2008 Monumenta exhibition at the Grand Palais in Paris, France is herein hypothesised to have stimulated the body’s vertical and longitudinal axes as it showcased 5 monumental rectangular solids pitched at a 1.69° angle.Using computerised dynamic posturography we measured the body sway of 23 visitors when fixating a cross, or when observing the artwork (fixating it or actively exploring it with eye movements before and after walking around and alongside the sculpture (i.e., before and after a promenade. A first fixation at the sculpture increased medio-lateral stability (in terms of spectral power of body sway. Eye movement exploration in the depth of the sculpture increased antero-posterior stability (in terms of spectral power and cancelling time of body sway at the expense of medio-lateral stability (in terms of cancelling time. Moreover, a medio-lateral instability associated with eye movement exploration before the promenade (in terms of body sway sensu stricto was cancelled after the promenade. Finally, the overall medio-lateral stability (in terms of spectral power increased after the promenade.Fourteen additional visitors were asked to sit in a dark room and adjust a luminous line to what they considered to be the earth-vertical axis. The promenade executed within the sculpted environment afforded by Serra’s monumental statuary works resulted in significantly improved performances on the subjective visual vertical test.We attribute these effects to the sculpted environment provided by the exhibition which may have acted as a kind of physiologic training ground thereby improving the visitors’ overall sense of visual perspective, equilibrium and gravity.

  3. Staging Unincorporated Power: Richard Harding Davis and the Critique of Imperial News

    Directory of Open Access Journals (Sweden)

    Nirmal Trivedi

    2011-12-01

    Full Text Available This essay contextualizes the work of war correspondent Richard Harding Davis within an evolving “imperial news apparatus” that would culminate in his reporting of the Spanish-American War. Critics have conventionally framed Davis squarely within the imperial cause, associating him with his admirer Roosevelt and naval admiral Alfred T. Mahan. Contrary to readings of Davis as an apologist for US imperialism, Trivedi contends that Davis understood how US imperial power relied on an information apparatus to communicate to an increasingly media-conscious American public through culture, that is, via familiar narratives, symbols, and objects—what Trivedi calls “imperial news.” The essay follows Davis’s development from his fictional representation of the new war correspondent in “The Reporter Who Made Himself King” to his own war correspondence before and after the Spanish-American War as collected in the memoirs A Year from a Reporter’s Notebook (1897, Cuba in War Time (1897, and Notes of a War Correspondent (1912. Davis’s war correspondence and fictional work effectively stage US imperialism as “unincorporated power”: that is, as power reliant on a developing news-making apparatus that deploys particular discursive strategies to validate its political claims. This staging critiques strategies of US imperial sovereignty—specifically its “privatization of knowledge” and its promotion of the war correspondent as nothing more than a spectator and purveyor of massacres.

  4. Charles Darwin, Richard Owen, and Natural Selection: A Question of Priority.

    No single author presented Darwin with a more difficult question about his priority in discovering natural selection than the British comparative anatomist and paleontologist Richard Owen. Owen was arguably the most influential biologist in Great Britain in Darwin's time. Darwin wanted his approbation for what he believed to be his own theory of natural selection. Unfortunately for Darwin, when Owen first commented in publication about Darwin's theory of descent he was openly hostile (Edinb. Rev. vol. 111, Article VIII, 1860, pp. 487-533, anonymous). Darwin was taken off-guard. In private meetings and correspondence prior to 1860 Owen had been nothing but polite and friendly, even helping Darwin in cataloguing and analyzing Darwin's zoological specimens from the Beagle voyage. Every early indication predicted a life-long friendship and collaboration. But that was not to be. Owen followed his slashing review with a mounting campaign in the 1860s to denounce and discredit both Darwin and his small but ascendant circle of friends and supporters. But that was not enough for Owen. Starting in 1866, perhaps by now realizing Darwin had landed the big fish, Owen launched a new campaign, to claim the discovery of "Darwin's theory" for himself. Darwin naturally fought back, mainly in the "Historical Sketch" that he prefaced to Origin starting in 1861. But when we peel back the layers of personal animus and escalating vituperation we discover in fact their quarrel was generated more by mutual misunderstanding than scientific disagreement. The battle ended only when Darwin finally penetrated to the crux of the matter and put an end to the rivalry in 1872, in the final version of the Sketch.

    It is a special privilege to receive this award honoring Richard Carrington's discovery of what we now call space weather. It is particularly appropriate that this award also recognizes Cherilynn Morrow, who 20 years ago made a presentation to the Space Science Advisory Committee on Jeff Rosendhal's idea of mission-based E/PO. We worked together, bringing that idea to the successful, but threatened, network it is today. For me, learning and teaching go hand in hand—as we publish our findings for our peers, we should also repay the public investment in our research with accurate, understandable results. My interest in space science was sparked by a father-daughter course in astronomy sponsored by the Brownies at the Oklahoma City Planetarium and kindled by the Bell Labs production The Strange Case of the Cosmic Rays directed by Frank Capra. Knowing that planetarium shows and educational movies can change lives, I have devoted a large portion of my last 25 years to creating software, shows, and portable planetariums to inspire and engage youth. This has not been a one-person effort, of course. My work Cherilynn Ann Morrow would have been impossible without the collaboration of Carolyn Sumners, vice president of the Houston Museum of Natural Science. Our museum kiosk and planetarium control software would not have happened without the skill and perseverance of my chief programmer, Colin Law. Jim Burch has been first a mentor and then a colleague on both the research and outreach sides of my career. I share this honor with a long line of highly talented students and postdocs who have contributed science content and outreach efforts. Most importantly, without the support of my husband, Tom Hill, I would not have had the time and freedom to build an educational network while continuing research and raising a family. I thank AGU for bestowing this honor.

    The assessment of sleep quality in critically ill patients is a relevant factor of high-quality care. Despite the fact that sleep disturbances and insufficient sleep management contain an increased risk of severe morbidity for these patients, a translated and applicable instrument to evaluate sleep is not available for German-speaking intensive care settings. This study aimed to translate the Richards Campbell Sleep Questionnaire (RCSQ), a simple and validated instrument eligible for measuring sleep quality in critically ill patients, and subsequently to evaluate the internal consistency of the German version of the RCSQ. Furthermore, it also aimed to inquire into the perception of sleep in a sample of critically ill patients. The RCSQ was translated following established methodological standards. Data were collected cross-sectionally in a sample of 51 patients at 3 intensive care units at a university hospital in Germany. The German version of the RCSQ showed an overall internal consistency (Cronbach's alpha) of 0·88. The mean of the RSCQ in the sample was 47·00 (SD ± 27·57). Depth of sleep was rated the lowest and falling asleep again the highest of the RCSQ sleep items. The study demonstrated very good internal consistency of the German version of the RCSQ, allowing for its application in practice and research in German-speaking countries. Quality of sleep perception was generally low in this sample, emphasizing the need for enhanced care concepts regarding the sleep management of critically ill patients. Relevance to clinical practice Assessment of self-perception of sleep is crucial in order to plan an individually tailored care process. © 2017 British Association of Critical Care Nurses.

  7. An Enlightenment proposal for music therapy: Richard Brocklesby on music, spirit, and the passions.

    Gouk, Penelope

    2015-01-01

    In 1749, the London physician Richard Brocklesby (1722-1797) published his Reflections on Antient [sic] and Modern Musick, an essay that not only sought to compare these practices in terms of their effects, but also to gather evidence supporting the use of music in treating mania and other mental diseases. As might be expected, Brocklesby's discussion of music therapy has already received attention by authors looking back to the origins of this practice, not least because he offers an account of a successful musical cure that took place in his own time (Rorke, 2001). My chapter, however, seeks to broaden the discussion of the Reflections, in order to show how Brocklesby's projected musical cures fit into his larger worldview, one that was influenced as much by Plato and other ancient philosophers as it was by modern thinkers such as Isaac Newton and his followers. Brocklesby's argument was essentially that music acted as a link between the mind and body and therefore could restore their intrinsic harmony, a connection that was mediated by the animal spirits, which also served as the vehicle of the passions. The movements and proportions of music could arouse or quell the passions by their effect on these (imaginary) spirits, which flowed through the nerves and brain and acted as the agent for the mind or soul. I show how his account of music in antiquity led him to reflect on the way that music was perceived and responded to in his own time, both as a stimulus to mental and bodily action, and as a source of esthetic pleasure through the cultivation of musical taste. © 2015 Elsevier B.V.

  8. An experimental 'Life' for an experimental life: Richard Waller's biography of Robert Hooke (1705).

    Moxham, Noah

    2016-03-01

    Richard Waller's 'Life of Dr Robert Hooke', prefixed to his edition of Hooke's Posthumous Works (1705), is an important source for the life of one of the most eminent members of the early Royal Society. It also has the distinction of being one of the earliest biographies of a man of science to be published in English. I argue that it is in fact the first biography to embrace the subject's natural-philosophical work as the centre of his life, and I investigate Waller's reasons for adopting this strategy and his struggle with the problem of how to represent an early experimental philosopher in print. I suggest that Waller eschews the 'Christian philosopher' tradition of contemporary biography - partly because of the unusually diverse and fragmentary nature of Hooke's intellectual output - and draws instead upon the structure of the Royal Society's archive as a means of organizing and understanding Hooke's life. The most quoted phrase from Waller's biography is that Hooke became 'to a crime close and reserved' in later life; this essay argues that Waller's biographical sketch was fashioned in order to undo the effects of that reserve. In modelling his approach very closely on the structure of the society's records he was principally concerned with making Hooke's work and biography accessible, intelligible and useful to the fellowship in a context familiar to them, a context which had provided the institutional framework for most of Hooke's adult life. I argue that Waller's 'Life' was also intended to make the largest claims for Hooke's intellectual standing that the author dared in the context of the enmity between Hooke and Isaac Newton once the latter became president of the Royal Society. However, I also adduce fresh manuscript evidence that Waller actually compiled, but did not publish, a defence of Hooke's claim to have discovered the inverse square law of gravity, allowing us to glimpse a much more assertive biography of Hooke than the published version.

  9. Timothy Leary, Richard Alpert (Ram Dass) and the changing definition of psilocybin.

    2010-05-01

    This research focuses on the events leading to the 1968 U.S. federal prohibition of psilocybin. It is a study of duelling moral entrepreneurs-Timothy Leary and Richard Alpert vs. the Harvard University Administration. The goal is to show how the primary active compound in an ostensibly harmless fungus (the psilocybin mushroom) became controversial in less than a decade. We used books, newspapers, magazine articles and previously unpublished materials (including documents from the Harvard Archives) to analyze Leary and Alpert's lives and careers through the early 1970s. The prohibition of psilocybin in the U.S. was largely a product of Leary and Alpert's involvement in the "Harvard drug scandal" and their transformation from Harvard professors to countercultural icons. They tested the substance on a variety of human subjects and in doing so piqued the interest of Harvard undergraduates while drawing condemnation from other faculty and Harvard administrators. This case is theoretically interesting because unlike most illegal drugs, psilocybin was never linked to a threatening minority group, but to some of the nation's most privileged youth. The Harvard administrators were not really moral entrepreneurs but Leary and Alpert clearly were. Although they were far from being prohibitionists, they were self-righteous crusaders on different but equally holy missions for the good of young and minority Americans. Ironically, due to their successes the possession of psilocybin was criminalized under United States federal law in 1968 (Pub. L. No. 90-639, Stat. 1361 1968 and Boire, 2002). This case study demonstrates that crusaders can be successful in changing culture even when laws are passed in futile attempts to control their behaviour, just as Leary predicted.

    2011-01-01

    As the world watched the Fukushima reactors release radionuclides into the ocean and atmosphere, the warnings of Dr. Alice Stewart about radiation risk and the reassurances of Sir Richard Doll assumed renewed relevance. Doll and Stewart, pioneer cancer epidemiologists who made major contributions in the 1950s-he by demonstrating the link between lung cancer and smoking, she by discovering that fetal X-rays double the chance of a childhood cancer-were locked into opposition about low-dose radiation risk. When she went public with the discovery that radiation at a fraction of the dose "known" to be dangerous could kill a child, her reputation plummeted, whereas Doll, foremost among her detractors, was knighted and lauded as "the world's most distinguished medical epidemiologist" for his work. Their lives and careers, so closely intertwined, took contrary courses, he becoming "more of the establishment" (as he said), while she became more oppositional. When it was discovered, after his death, that he'd been taking large sums of money from industries whose chemicals he was clearing of cancer risk, his reputation remained unscathed; it is now enshrined in the "Authorized Biography" (2009) commissioned by the Wellcome Institute, along with Doll's denigration of Stewart as an "embittered" woman and biased scientist. Stewart lived long enough to see radiation science move her way, to see international committees affirm, in the 1990s, that there is no threshold beneath which radiation ceases to be dangerous; recent evidence from Chernobyl is bearing out her warnings. But a look at the making and breaking of these reputations reveals the power of status, position, and image to shape scientific "knowledge" and social policy.

    The study discloses that the redox activity of N-(1,4-naphthoquinone)-o-aminophenol derivatives (L R H 2 ) containing a (phenol)-NH-(1,4-naphthoquinone) fragment is notably different from that of a (phenol)-NH-(phenol) precursor. The former is a platform for a redox cascade. L R H 2 is redox noninnocent and exists in Cat-N-(1,4-naphthoquinone)(2-) (L R 2- ) and SQ-N-(1,4-naphthoquinone) (L R •- ) states in the complexes. Reactions of L R H 2 with cobalt(II) salts in MeOH in air promote a cascade affording spiro oxazine-oxazepine derivatives ( OX L R ) in good yields, when R = H, Me, t Bu. Spiro oxazine-oxazepine derivatives are bioactive, and such a molecule has so far not been isolated by a schematic route. In this context this cascade is significant. Dimerization of L R H 2 → OX L R in MeOH is a (6H + + 6e) oxidation reaction and is composed of formations of four covalent bonds and 6-exo-trig and 7-endo-trig cyclization based on C-O coupling reactions, where MeOH is the source of a proton and the ester function. It was established that the active cascade precursor is [(L Me •- )Co III Cl 2 ] (A). Notably, formation of a spiro derivative was not detected in CH 3 CN and the reaction ends up furnishing A. The route of the reaction is tunable by R, when R = NO 2 , it is a (2e + 4H + ) oxidation reaction affording a dinuclear L R 2- complex of cobalt(III) of the type [(L NO2 2- ) 2 Co III 2 (OMe) 2 (H 2 O) 2 ] (1) in good yields. No cascade occurs with zinc(II) ion even in MeOH and produces a L Me •- complex of type [(L Me •- )Zn II Cl 2 ] (2). The intermediate A and 2 exhibit strong EPR signals at g = 2.008 and 1.999, confrming the existence of L Me •- coordinated to low-spin cobalt(III) and zinc(II) ions. The intermediates of L R H 2 → OX L R conversion were analyzed by ESI mass spectrometry. The molecular geometries of OX L R and 1 were confirmed by X-ray crystallography, and the spectral features were elucidated by TD DFT calculations.

    Full Text Available We synthesized two series of androstane derivatives as inhibitors of type 3 and type 5 17β-hydroxysteroid dehydrogenases (17β-HSDs. In the first series, four monospiro derivatives at position C17 were prepared from androsterone (ADT or epi-ADT. After the protection of the alcohol at C3, the C17-ketone was alkylated with the lithium acetylide of tetrahydro-2-(but-3-ynyl-2-H-pyran, the triple bond was hydrogenated, the protecting groups hydrolysed and the alcohols oxidized to give the corresponding 3-keto-17-spiro-lactone derivative. The other three compounds were generated from this keto-lactone by reducing the ketone at C3, or by introducing one or two methyl groups. In the second series, two dispiro derivatives at C3 and C17 were prepared from epi-ADT. After introducing a spiro-δ-lactone at C17 and an oxirane at C3, an aminolysis of the oxirane with L-isoleucine methyl ester provided an amino alcohol, which was treated with triphosgene or sodium methylate to afford a carbamate- or a morpholinone-androstane derivative, respectively. These steroid derivatives inhibited 17β-HSD3 (14–88% at 1 μM; 46–94% at 10 μM and 17β-HSD5 (54–73% at 0.3 μM; 91–92% at 3 μM. They did not produce any androgenic activity and did not bind steroid (androgen, estrogen, glucocorticoid and progestin receptors, suggesting a good profile for prostate cancer therapy.

  16. The effects of coal dust on photosynthetic performance of the mangrove, Avicennia marina in Richards Bay, South Africa

    Richards Bay, on the northern KwaZulu-Natal coast, is the largest coal exporting port in South Africa. The coal is stored at the Richards Bay Coal Terminal (RBCT) prior to export. Dust from coal operations is a major problem in the Richards Bay area. In this study, we tested the hypothesis that coal dust adversely affects photosynthetic performance of Avicennia marina (Forssk.) Vierh., the dominant mangrove species in the harbour. Photosynthetic performance was determined on 10 trees by measuring carbon dioxide uptake and chlorophyll fluorescence parameters at two elevation sites and on upper and lower leaf surfaces that were covered or uncovered with coal dust. Measurements were made on five clear, sunny days at saturating light (>1000 μmol m -2 s -1 ) and high temperature (28-30 deg. C). Coal dust significantly reduced carbon dioxide exchange of upper and lower leaf surfaces by 17-39%, the reduction being generally greater on the lower leaf surface that is covered by a dense mat of trichomes and salt glands. The reduction in carbon dioxide exchange by coal dust was higher at the high elevation site that supported isolated dwarfed trees. The chlorophyll fluorescence data indicated that leaves coated with dust exhibited significantly lower photosystem II (PS II) quantum yield, lower electron transport rate (ETR) through PSII and reduced quantum efficiency of PSII (F v F m ). The chlorophyll fluorescence data supported the gas exchange measurements and are consistent with reduced photosynthetic performance of leaves coated with coal dust. - Coal dust reduced photosynthetic performance of the mangrove, Avicennia marina

    A total of eight commercial spaceflight participants have launched to the International Space Station (ISS) on Soyuz vehicles. Based on an older mean age compared to career astronauts and an increased prevalence of medical conditions, spaceflight participants have provided the opportunity to learn about the effect of space travel on crewmembers with medical problems. The 12-d Soyuz TMA-13/12 ISS flight of spaceflight participant Richard Garriott included medical factors that required preflight intervention, risk mitigation strategies, and provided the opportunity for medical study on-orbit. Equally important, Mr. Garriott conducted extensive medical, scientific, and educational payload operations during the flight. These included 7 medical experiments and a total of 15 scientific projects such as protein crystal growth, Earth observations/photography, educational projects with schools, and amateur radio. The medical studies included the effect of microgravity on immune function, sleep, bone loss, corneal refractive surgery, low back pain, motion perception, and intraocular pressure. The overall mission success resulted from non-bureaucratic agility in mission planning, cooperation with investigators from NASA, ISS, International Partners, and the Korean Aerospace Research Institute, in-flight support and leadership from a team with spaceflight and Capcom experience, and overall mission support from the ISS program. This article focuses on science opportunities that suborbital and orbital spaceflight participant flights offer and suggests that the science program on Richard Garriott's flight be considered a model for future orbital and suborbital missions. The medical challenges are presented in a companion article.

In 1947 Jean Vilar opened the first Avignon Festival with an ascetic, charismatic eponymous hero who came to an inner knowledge of himself in his bare prison cell; in 1982 Ariane Mnouchkine offered a splendid visual display by transposing the play into the kabuki tradition; this offered the audience breath-taking and dynamic tableaux of elaborate court ceremonies and rebellious lords.At such a distance in time, the English medieval code of honour was dealt with according to completely different theatrical principles of ethics and aesthetics, mirroring the changes in perspective within French society.

Regarding the former topic, the goal will be to highlight the ambiguity of those Owen’s remarks, and concerning the latter topic what is looked for is to show that, when he explained his transmutationist thesis, Owen didn’t go beyond a pious theistic evolutionism, without postulating any mechanism of evolutionary change and remaining faithful to Design Theology praised by Paley.

  5. HOW CAN LOVE BE VIOLENT? REFLECTIONS ON RICHARD OF ST.VICTOR’S ON THE FOUR DEGREES OF VIOLENT LOVE

    Directory of Open Access Journals (Sweden)

    MARIUS TALOŞ

    2012-05-01

    Full Text Available The following article focuses on Richard of St. Victor´s most original treatise: On the Four Degrees of Violent Love. Although the topic of violence within the Christian view on ethics, politics and theology was not at all new by 1173, the major contribution of this short but dense mystical writing consists in developing systematically the violence as an inherent consequence of the infinite charity. The love is so powerful that it “wounds, binds, languishes and brings on a faint”, but the same force may have different effects: if these four steps appear to be destructive when oriented to satisfy the “profane” desires, their infinite strength show providential effects when turned to the divine source of the charity.

    Full Text Available In general, two theories or school of thoughts had been prevailed in modern moral philosophies until recently. Ethical school of thought of "task-oriented", in which the emphasis is on the nature of the action. At first, this school of thought was considered by Immanuel Kant. Accordingly, doing or will to do every action should be such that become a universal moral law. In contrast, another ethical school of thought known as "utilitarianism ethics" was introduced by Jeremy Bentham and John Stuart Mill. Here, we give priority to those moral actions that can bring the greatest happiness for most people. In three or four recent decades, coinciding with the linguistic and cognitive turn, which has become known as the transition from positivism to post-positivism, another challenge has been raised in discussing philosophy of ethics by Richard Rorty which is related to his claim regarding the requirements of the current multiple world. This claim can make a new relation between morality and human rights. Hence, the main hypothesis of this paper is to clarify the point that Rorty has raised his claim by combining the theory of pragmatism and postmodern Ethics. To prove this hypothesis, this article has been set in two sections, in the first section in order to become familiar with Rorty's creed-breaker thought, the foundations of the philosophy of ethics is discussed. In the second section and under the discussion of ethics based on the rights of human, some of its characteristics will be analyzed. This article has been prepared by a descriptive method through the content analysis of various works of Rorty. Theoretical support for this article is a critical-normative approach. به طور کلی در فلسفه‌های اخلاق مدرن تا این اواخر دو نگره یا مکتب حاکم بوده است. مکتب اخلاق «وظیفه‌گرا»که در آن بر ماهیت کنش تأکید می‌شود. این مکتب ابتدا

  10. You Don't Need Richards'... A New General 1-D Vadose Zone Solution Method that is Reliable

    2015-12-01

    Hydrologic modelers and mathematicians have strived to improve 1-D Richards' equation (RE) solution reliability for predicting vadose zone fluxes. Despite advances in computing power and the numerical solution of partial differential equations since Richards first published the RE in 1931, the solution remains unreliable. That is to say that there is no guarantee that for a particular set of soil constitutive relations, moisture profile conditions, or forcing input that a numerical RE solver will converge to an answer. This risk of non-convergence renders prohibitive the use of RE solvers in hydrological models that need perhaps millions of infiltration solutions. In lieu of using unreliable numerical RE solutions, researchers have developed a wide array of approximate solutions that more-or-less mimic the behavior of the RE, with some notable deficiencies such as parameter insensitivity or divergence over time. The improved Talbot-Ogden (T-O) finite water-content scheme was shown by Ogden et al. (2015) to be an extremely good approximation of the 1-D RE solution, with a difference in cumulative infiltration of only 0.2 percent over an 8 month simulation comparing the improved T-O scheme with a RE numerical solver. The reason is that the newly-derived fundamental flow equation that underpins the improved T-O method is equivalent to the RE minus a term that is equal to the diffusive flux divided by the slope of the wetting front. Because the diffusive flux has zero mean, this term is not important in calculating the mean flux. The wetting front slope is near infinite (sharp) in coarser soils that produce more significant hydrological interactions between surface and ground waters, which also makes this missing term 1) disappear in the limit, and, 2) create stability challenges for the numerical solution of RE. The improved T-O method is a replacement for the 1-D RE in soils that can be simulated as homogeneous layers, where the user is willing to neglect the effects

    Full Text Available Vanishing Point (Richard C. Sarafian, 1971, Two-lane Blacktop (Monte Hellmann, 1971 and Badlands (Terrence Malick, 1973 are road movies that incorporate distinctive journeys, which, at a certain moment, become similar. Their heroes act as non-mystical pilgrims to whom the trip is a journey in itself, even if they come up as a chase, a car race or an escape from the police.In a filmic genre built from the spatial element, the road life structures each narrative in each film. In this way, the moment when the journey looses its teleological sense acquires even more relevance, allowing us to understand the genre’s space dynamics with a different depth.In this essay, I will analyse comparatively the ways through which characters and directors relate to the scenery/landscape, in order to identify ideological constraints related to space, i.e., those symbolic limitations the road movie seems to conceal. Easy Rider (Dennis Hopper, 1969 will be a constant presence since, as the inaugural road movie, it has determined the genre’s underlying forces.

  13. An analytical solution of Richards' equation providing the physical basis of SCS curve number method and its proportionality relationship

    Hooshyar, Milad; Wang, Dingbao

    2016-08-01

    The empirical proportionality relationship, which indicates that the ratio of cumulative surface runoff and infiltration to their corresponding potentials are equal, is the basis of the extensively used Soil Conservation Service Curve Number (SCS-CN) method. The objective of this paper is to provide the physical basis of the SCS-CN method and its proportionality hypothesis from the infiltration excess runoff generation perspective. To achieve this purpose, an analytical solution of Richards' equation is derived for ponded infiltration in shallow water table environment under the following boundary conditions: (1) the soil is saturated at the land surface; and (2) there is a no-flux boundary which moves downward. The solution is established based on the assumptions of negligible gravitational effect, constant soil water diffusivity, and hydrostatic soil moisture profile between the no-flux boundary and water table. Based on the derived analytical solution, the proportionality hypothesis is a reasonable approximation for rainfall partitioning at the early stage of ponded infiltration in areas with a shallow water table for coarse textured soils.

    Full Text Available O texto discute o sentido polémico do “regresso” a África que Richard Wright inscreve em Black Power e a forma como a narrativa da viagem subverte a “Middle Passage”. O sujeito narrativo orienta o leitor através de uma incursão pessoal nos muitos sentidos da modernidade e desdobra a noção de “destino comum”, já apontada em 12 Million Black Voices. Contudo, qualquer sentido de comunidade é aqui necessariamente ambíguo, por estar sempre relacionado com questões de raça e identidade. Black Power é uma narrativa importante para o conceito de modernidade e assinala uma mudança significativa na produção literária de Wright para uma vertente não-ficcional. Esta segunda fase da sua obra contém, no entanto, um paradoxo crucial: enquanto se volta para o exterior, para o mundo mais global, Wright tenta, simultaneamente, inscrever-se como referência sobre o locus do qual nunca poderia demarcar‑se: África. Em Black Power, a duboisiana “color line” desdobra‑se em múltiplas dimensões.

  15. ‘The Edification of the Church’: Richard Hooker’s Theology of Worship and the Protestant Inward / Outward Disjunction

    Directory of Open Access Journals (Sweden)

    Littlejohn W. Bradford

    2014-06-01

    Full Text Available Sixteenth-century English Protestants struggled with the legacy left them by the Lutheran reformation: a strict disjunction between inward and outward that hindered the development of a robust theology of worship. For Luther, outward forms of worship had more to do with the edification of the neighbour than they did with pleasing God. But what exactly did ‘edification’ mean? On the one hand, English Protestants sought to avoid the Roman Catholic view that certain elements of worship held an intrinsic spiritual value; on the other hand, many did not want to imply that forms of worship were spiritually arbitrary and had a merely civil value. Richard Hooker developed his theology of worship in response to this challenge, seeking to maintain a clear distinction between the inward worship of the heart and the outward forms of public worship, while refusing to disassociate the two. The result was a concept of edification which sought to do justice to both civil and spiritual concerns, without, pace Peter Lake and other scholars, conceding an inch to a Catholic theology of worship

  16. [Some remarks on the theory of sets by Richard Dedekind and Stanisław Leśniewski].

    Mereology, is a part-whole theory, also called the theory of collective sets. It was founded in 1916 by Stanisław Leśniewski and this is an alternative theory versus the classical set theory by Georg Cantor. These two theories are usually teamed up together as Leśniewski himself was referring to the concept of the set by Cantor and Cantor is considered the "main" ideologist of the set theory. However, when analyzing the original texts of various authors, it seems that the very concept of a collective set is closer to the idea of Richard Dedekind rather than that of Georg Cantor. It is known that Cantor borrowed some concepts on the notion of set from Dedekind, whose ideas were also known to Leśniewski, however, there is no study on this topic. This work is therefore an attempt to compare some set-theoretical concepts of both of these authors, i.e. S. Leśiewski and R. Dedekind and the presentation of their convergence.

    A novel exciplex-forming host is applied so as to design highly simplified reddish orange light-emitting diodes (OLEDs) with low driving voltage, high efficiency, and an extraordinarily low efficiency roll-off, by combining N,N-10-triphenyl-10H-spiro [acridine-9,9'-fluoren]-3'-amine (SAFDPA) with 4,7-diphenyl-1,10-phenanthroline (Bphen) doped with trivalent iridium complex bis(2-methyldibenzo[f,h]quinoxaline) (acetylacetonate)iridium(III) (Ir(MDQ) 2 (acac)). The reddish orange OLEDs achieve a strikingly high power efficiency (PE) of 31.80 lm/W with an ultralow threshold voltage of 2.24 V which is almost equal to the triplet energy level of the phosphorescent reddish orange emitting dopant. The power efficiency of the device with the exciplex-forming host is enhanced, achieving 36.2% mainly owing to the lower operating voltage by the novel exciplex forming cohost, compared with the reference device (23.54 lm/W). Moreover, the OLEDs show extraordinarily low current efficiency (CE) roll-off to 1.41% at the brightness from 500 to 5000 cd/m 2 with a maximal CE of 32.87 cd/A (EQE max = 11.01%). The devices display a good reddish orange color (CIE of (0.628, 0.372) at 500 cd/m 2 ) nearly without color shift with increasing brightness. Co-host architecture phosphorescent OLEDs show a simpler device structure, lower working voltage, and a better efficiency and stability than those of the reference devices without the cohost architecture, which helps to simplify the OLED structure, lower the cost, and popularize OLED technology.

    2017-12-01

    Full Text Available The article deals with a case from the creative history of Leo Tolstoy’s The Circle of Reading (1908, when Tolstoy included the revised story of Guy de Maupassant’s Le Port under the title “Sisters” in the second edition of the book. The author proves that the reason for Tolstoy’s decision was his polemic with “saninstvo” as one of the most fashionable ethical trends of the first decade of the 1900s. The key component of Sanin’s behavior and hedonistic philosophy in Mikhail Artsybashev’s novel was incest. Maupassant’s novella is based on the same plot. On the basis of Tolstoy’s nonfictional texts of the 1890s, including the treatise What Is Art? (1898, the article reconstructs the writer’s view on the forms and boundaries of the representation of incest in Richard Wagner’s operas and in Friedrich Nietzsche’s philosophy, with which Tolstoy also polemicized and in connection with which he stated the ethical potential of art and its permissiveness. From this perspective, Tolstoy’s reaction to Artsybashev’s novel, combining the motives of incest and extreme individualism, turns out to be a new phase of the old dispute. Tolstoy included the story “Sisters” in the second edition of The Circle of Reading as a response to the philosophy of “saninstvo.” Thus, Tolstoy’s collection of wise thoughts can be considered not only as didactic, but also as a polemical text, and deeply rooted in the ideological context of the 1890s‒1900s.

    This Basic Award allowed for the funding of student scholarships to the Richard Tapia Celebration of Diversity in Computing Conference which took place in Washington, D.C. from February 7-10, 2013. The conference was the seventh in a series and included a stellar array of invited speakers, compelling panel discussions, a student poster competition, a daylong Doctoral Consortium, a session featuring a choice of attractions unique to Washington, D.C., a gala banquet and dance, and many exciting networking opportunities. The conference created a welcoming environment for STEM students, especially underrepresented minority and female students, who were provided the highest quality of learning, networking, and social experiences to empower their educational experience and enhance their ability to succeed with a rigorous STEM degree. The networking and mentoring opportunities available at the conference were also designed to empower students to succeed in STEM careers and ultimately serve in leadership in industry and the professoriate. A key step in attracting underrepresented students into STEM fields and paving the way for their success in influential positions is to create a nurturing and supportive network and community for them to rely upon. It is also critical to educate leaders in corporations, government and academia about the benefits to be gained from increasing the percentage of STEM professionals from underrepresented groups. To this end, The Tapia Conference serves both functions, as it connects STEM students with STEM professionals, leaders, and academics who share the vision of a STEM workforce and community that is truly representative of the community in which we live.

  1. Evaluation of the Ross fast solution of Richards' equation in unfavourable conditions for standard finite element methods

    2009-01-01

    Ross [Ross PJ. Modeling soil water and solute transport - fast, simplified numerical solutions. Agron J 2003;95:1352-61] developed a fast, simplified method for solving Richards' equation. This non-iterative 1D approach, using Brooks and Corey [Brooks RH, Corey AT. Hydraulic properties of porous media. Hydrol. papers, Colorado St. Univ., Fort Collins: 1964] hydraulic functions, allows a significant reduction in computing time while maintaining the accuracy of the results. The first aim of this work is to confirm these results in a more extensive set of problems, including those that would lead to serious numerical difficulties for the standard numerical method. The second aim is to validate a generalisation of the Ross method to other mathematical representations of hydraulic functions. The Ross method is compared with the standard finite element model, Hydrus-1D [Simunek J, Sejna M, Van Genuchten MTh. The HYDRUS-1D and HYDRUS-2D codes for estimating unsaturated soil hydraulic and solutes transport parameters. Agron Abstr 357; 1999]. Computing time, accuracy of results and robustness of numerical schemes are monitored in 1D simulations involving different types of homogeneous soils, grids and hydrological conditions. The Ross method associated with modified Van Genuchten hydraulic functions [Vogel T, Cislerova M. On the reliability of unsaturated hydraulic conductivity calculated from the moisture retention curve. Transport Porous Media 1988:3:1-15] proves in every tested scenario to be more robust numerically, and the compromise of computing time/accuracy is seen to be particularly improved on coarse grids. Ross method run from 1.25 to 14 times faster than Hydrus-1D. (authors)

  2. ‘By Force of Participation and Conjunction in Him’: John Jewel and Richard Hooker on Union with Christ

    Directory of Open Access Journals (Sweden)

    Gazal André A.

    2014-06-01

    Full Text Available The author of a Christian Letter cited a passage from John Jewel’s A Reply to Harding’s Answer in which the first major apologist of the Elizabethan Settlement spoke of the role of faith and the sacraments in union with Christ. Andrew Willet, the likely author of this work, quoted it against Richard Hooker in order to show how the latter contravened the sacramental theology of the national Church as interpreted by Jewel as one of the foremost expositors of its doctrine. Jewel, however, in his Reply to Harding’s Answer, enumerates four means of the Christian’s union with Christ: the Incarnation, faith, baptism, and the Eucharist-a fact overlooked in A Christian Letter by its author in his endeavor to impeach Hooker’s orthodoxy. Proceeding from the observation that both Jewel and Hooker believed that the locus of Christian salvation is union with Christ, this essay compares the two divines’ respective views of this union by examining the manner in which they understand the role of each of these means forming and maintaining this union. On the basis of this comparison, the essay argues that A Christian Letter misrepresented Jewel’s position and that Hooker’s view of union with Christ was essentially the same as the late bishop of Salisbury’s, notwithstanding some differences in detail and emphases. The article concludes with the opinion that Hooker represents continuity of a particular soteriological emphasis in the Elizabethan Church that can possibly be traced back to Jewel as a representative of the Reformed tradition stressing this doctrine.

    2001-01-01

    This paper examines the social thought of University of Wisconsin professors Richard T. Ely, John R. Commons, and Edward A. Ross during World War I. Like many of their fellow scholars, these three were actively involved in the pro-war effort. Although their support for the war was strongly conditioned by personal and occupational considerations, the impact of their wartime service was not restricted to those realms. Their social thought, which they impressed into service explaining and justifying the war, was itself altered in subtle and sometimes surprising ways by the forceful positions they took on the political, economic, and racial significance of the conflict.

    Full Text Available Este artigo examina o pensamento filosófico de Richard Rorty e, em particular, sua dimensão política, delineando seu tratamento original e crítico de temas centrais à teoria política contemporânea. O objetivo do texto é triplo: chamar a atenção para a fertilidade das ideias de um autor ainda pouco lido no Brasil (i, assinalar as notáveis consequências corrosivas da abordagem rortyana para pressupostos e pretensões fundantes de importantes vertentes da teoria política (ii, e, numa ótica mais positiva, apontar o potencial inspirador dos escritos desse autor para a reflexão sobre novos modos de justificação da democracia (iii. Salientam-se também, nesse último caso, os limites impostos a esse tipo de empreitada político-intelectual. A abordagem empregada consiste em demarcar os contornos gerais do projeto filosófico do autor, seguindo-se uma apresentação dos tópicos mais propriamente políticos da obra de Rorty. Mais especificamente, o artigo explora a proposta rortyana de substituição da noção de verdade pela de justificação, assinalando-se suas consequências para pretensões de verdade, objetividade e universalismo, presentes em diversas linhas da teoria política. Nesse veio, o artigo discute as eventuais implicações relativistas das teses rortyanas, chegando-se, por essa rota, às ideias de contingência, imaginação e persuasão, núcleos conceituais vitais à reflexão em tela. Um breve contraste com posições de autores como Habermas e Rawls, caros ao próprio Rorty, é esboçado no propósito de tornar mais clara a especificidade da abordagem rortyana da política. Transitando, do modo assinalado, por esses tópicos, o texto resulta em um panorama sintético da perspectiva rortyana acerca do que vem a ser, contemporaneamente, uma "política democrática", liberta de "universalismos" e "objetividades", na qual ganham estatuto decisivo questões de justificação, tolerância e coexist

    Full Text Available The real cause of Soeharto’s fall from the Indonesian presidency remains a mystery. Richard Mann (1998 launched three significant rhetorical questions: (a Was President Soeharto toppled by student demonstrators and people’s power? (b Was he brought down by the withdrawal of support from the United States? (c Or, was his sudden fall brought about by all of the two plus large doses of Oriental plotting and scheming? This article attempts to analyze Richard Mann’s PSBDS in terms of its macrostructure in order to find out the real cause of Soeharto’s fall. The analysis is substantiated by different resources as linguistic evidences, to justify the validity of the findings. The study revealed a proposition that critical reading is the key to successful comprehension of a text which may include a crosschecking with other resources, a careful identification of the generic structure of a text, and paying attention to how an author positions his or her readers. The article concludes, that in fact, Soeharto resigned from presidency on his own wisdom in order to avoid more bloodshed in Indonesian dreamland.

  16. Kalman filters for assimilating near-surface observations into the Richards equation - Part 2: A dual filter approach for simultaneous retrieval of states and parameters

    Science.gov (United States)

    Medina, H.; Romano, N.; Chirico, G. B.

    2014-07-01

    This study presents a dual Kalman filter (DSUKF - dual standard-unscented Kalman filter) for retrieving states and parameters controlling the soil water dynamics in a homogeneous soil column, by assimilating near-surface state observations. The DSUKF couples a standard Kalman filter for retrieving the states of a linear solver of the Richards equation, and an unscented Kalman filter for retrieving the parameters of the soil hydraulic functions, which are defined according to the van Genuchten-Mualem closed-form model. The accuracy and the computational expense of the DSUKF are compared with those of the dual ensemble Kalman filter (DEnKF) implemented with a nonlinear solver of the Richards equation. Both the DSUKF and the DEnKF are applied with two alternative state-space formulations of the Richards equation, respectively differentiated by the type of variable employed for representing the states: either the soil water content (θ) or the soil water matric pressure head (h). The comparison analyses are conducted with reference to synthetic time series of the true states, noise corrupted observations, and synthetic time series of the meteorological forcing. The performance of the retrieval algorithms are examined accounting for the effects exerted on the output by the input parameters, the observation depth and assimilation frequency, as well as by the relationship between retrieved states and assimilated variables. The uncertainty of the states retrieved with DSUKF is considerably reduced, for any initial wrong parameterization, with similar accuracy but less computational effort than the DEnKF, when this is implemented with ensembles of 25 members. For ensemble sizes of the same order of those involved in the DSUKF, the DEnKF fails to provide reliable posterior estimates of states and parameters. The retrieval performance of the soil hydraulic parameters is strongly affected by several factors, such as the initial guess of the unknown parameters, the wet or dry

  18. Exact and grid-free solutions to the Lighthill-Whitham-Richards traffic flow model with bounded acceleration for a class of fundamental diagrams

    KAUST Repository

    Qiu, Shanwen

    2013-09-01

    In this article, we propose a new exact and grid-free numerical scheme for computing solutions associated with an hybrid traffic flow model based on the Lighthill-Whitham-Richards (LWR) partial differential equation, for a class of fundamental diagrams. In this hybrid flow model, the vehicles satisfy the LWR equation whenever possible, and have a constant acceleration otherwise. We first propose a mathematical definition of the solution as a minimization problem. We use this formulation to build a grid-free solution method for this model based on the minimization of component function. We then derive these component functions analytically for triangular fundamental diagrams, which are commonly used to model traffic flow. We also show that the proposed computational method can handle fixed or moving bottlenecks. A toolbox implementation of the resulting algorithm is briefly discussed, and posted at https://dl.dropbox.com/u/1318701/Toolbox.zip. © 2013 Elsevier Ltd.

    During the years 1714 to 1721, Richard Bradley, who was later to become the first Professor of Botany at Cambridge University, proposed a unified, unique, living agent theory of the cause of infectious diseases of plants and animals and the plague of humans. Bradley's agents included microscopic organisms, revealed by the studies of Robert Hooke and Antony van Leeuwenhoek. His theory derived from his experimental studies of plants and their diseases and from microscopic observation of animalcules in different naturally occurring and artificial environments. He concluded that there was a microscopic world of "insects" that lived and reproduced under the appropriate conditions, and that infectious diseases of plants were caused by such "insects." Since there are structural and functional similarities between plants and animals, Bradley concluded that microscopic organisms caused human and animal infectious diseases as well. However, his living agent cause of infectious diseases was not accepted by the contemporary scientific society.

In this hybrid flow model, the vehicles satisfy the LWR equation whenever possible, and have a fixed acceleration otherwise. We first present a grid-free solution method for the LWR equation based on the minimization of component functions. We then show that this solution method can be extended to compute the solutions to the hybrid model by proper modification of the component functions, for any concave fundamental diagram. We derive these functions analytically for the specific case of a triangular fundamental diagram. We also show that the proposed computational method can handle fixed or moving bottlenecks.

    Richard L.

He describes how his firm is putting financial and clinical tools in the hands of consumers and physicians, so consumers can be more enlightened in their health care choices. Danaher says, "We're not about buying goods and services online. We are transforming the way consumers buy health care and seek insurance. We're trying to be a 401 k where people get on, knowing their risk profile and return horizons. We aim to motivate consumers to be proactive in making health care choices. How do we make consumers responsible and motivated enough to take control of managing their health care costs? How well we articulate this call to consumer action will be the key to our success."

    Directory of Open Access Journals (Sweden)

    Jonathan A. Draper

    2009-08-01

    Full Text Available This paper examines the attempt by Richard Burridge in his recent book, Imitating Jesus: An inclusive approach to New Testament ethics (2007, to build an engaged Christian ethics starting with the historical Jesus but taking full account of the insights into the perspectives of the four gospels in their own right, based on their genre as Greek bioi. While Burridge’s approach is applauded and regarded as a major step forward, it is critiqued here on his selectivity in his presentation of the results of two decades of research into the Jesus of history. Burridge’s selection of the South African experience in the struggle against apartheid as his ‘test case’ is also questioned, since the issues in such struggles for justice appear more straightforward to outsiders than they do to insiders and his analysis raises more questions than it answers.

  5. Will the real Robert Neville please, come out? Vampirism, the ethics of queer monstrosity, and capitalism in Richard Matheson's I am legend?

    Science.gov (United States)

    Khader, Jamil

    2013-01-01

    In this article, I argue that Richard Matheson's (1954) vampire novella, I Am Legend, encodes the protagonist's, Robert Neville, traumatic recognition of his queer sexuality in its monstrosity (the unspeakability of male penetrability). Neville's identification with and desire for his undead neighbor, Ben Cortman, are symbolically codified through three different registers: intertextual references to vampiric conventions and codes, the semiotics of queer subculture, and a structure of doubling that links Neville to the queer vampire. Although Neville avoids encountering his unspeakable queer desire, which could be represented only at the level of the Lacanian Real, he must still confront Cortman's obsessive exhortations for him to come out. Only when he symbolically codifies his abnormality in its own monstrosity, by viewing himself through mutant vampires' eyes, can Neville reconfigure the ethical relationship between self and other, humans and mutant humans-vampires. However progressive Matheson's novella is in its advocacy of minority sexual rights, it still renders capitalism's problematic relationship with queer subjectivity invisible. Although capitalism overdetermines every aspect of the social field and makes Neville's daily life possible in its surplus enjoyment, the fundamental antagonism (class struggle) in capitalism is obscured by the assertion of identity politics.

    We present a dual Kalman Filter (KF) approach for retrieving states and parameters controlling soil water dynamics in a homogenous soil column by using near-surface state observations. The dual Kalman filter couples a standard KF algorithm for retrieving the states and an unscented KF algorithm for retrieving the parameters. We examine the performance of the dual Kalman Filter applied to two alternative state-space formulations of the Richards equation, respectively differentiated by the type of variable employed for representing the states: either the soil water content (θ) or the soil matric pressure head (h). We use a synthetic time-series series of true states and noise corrupted observations and a synthetic time-series of meteorological forcing. The performance analyses account for the effect of the input parameters, the observation depth and the assimilation frequency as well as the relationship between the retrieved states and the assimilated variables. We show that the identifiability of the parameters is strongly conditioned by several factors, such as the initial guess of the unknown parameters, the wet or dry range of the retrieved states, the boundary conditions, as well as the form (h-based or θ-based) of the state-space formulation. State identifiability is instead efficient even with a relatively coarse time-resolution of the assimilated observation. The accuracy of the retrieved states exhibits limited sensitivity to the observation depth and the assimilation frequency.

    Full Text Available Epiphytic orchids have received considerable study, yet little has been published on their germination requirements in situ involving mycorrhizal fungi. Such research has been hampered by the small, dust-like size of seeds and leafless seedlings (protocorms which are difficult to pinpoint on natural substrates, especially those on arboreal substrates (tree limbs. We report a novel seed sowing and retrieval method, modified from one applied to terrestrial orchids, used in the acquisition of epiphytic orchid protocorms from the Florida Panther National Wildlife Refuge. Seeds from two epiphytic orchid species (Epidendrum amphistomum A. Richard, E. nocturnum Jacquin were placed in separate nylon mesh packets secured within 35 mm plastic slide mounts, and affixed to tree bark using gutter mesh and a staple gun. To confirm that the embryos were viable, some seeds were also sown on asymbiotic media in the laboratory which subsequently germinated after 52 days incubation. Of 60 packets distributed among 18 tree limb sites, one packet – harboring seeds of E. amphistomum affixed to pop ash (Fraxinus caroliniana Mill. on a moss substrate – harbored protocorms after 267 days. Using molecular markers, a fungus assignable to the Ceratobasidiaceae, appears to be the mycorrhizal associate of these protocorms suggesting that this fungus may be associated with the germination process in situ.

    The conference was related with some of the major questions concerning global energy governance today, the role of the different international organizations dealing with energy, the rules of the game between market and state players, the efforts to deal with climate change, and the integration of emerging countries in global energy governance, the roles of the different international organizations dealing with energy (will we see further fragmentation or more cooperation between them?). Tatsuo Masuda in his contribution discussed global energy governance from an oil perspective. Andre Mernier noted the particular nature of the Energy Charter, which, as it is founded upon an international treaty, is unlike other organizations in being legally binding. The legal basis of the organization means that agreements are especially powerful. Then Richard H. Jones underlined that last summer's volatility in oil markets, the ensuing financial and economic crisis, the major disruption in gas supplies to European markets this winter and the upcoming climate change negotiations have led to increasing calls for a stronger global dialogue on energy issues. This dialogue should deal with prices and investment, energy security and climate change

Gli aspetti salienti del quadrante orientale della periferia romana verranno così delineati partendo “dal di dentro”, sottolineandone i percorsi, gli spazi e i nuclei compositivi che sono all’origine della struttura e della forma stessa dei quartieri disposti a cavallo del Grande Raccordo Anulare. In questo ambito, si pone l’attenzione su alcuni episodi chiave che vedono protagoniste le nuove chiese che riescono a creare una centralità all’interno dei quartieri periferici sostituendo le biblioteche, le piazze e i centri commerciali.  Analizzando da vicino questi esempi, si scopre come di recente sono state realizzate chiese firmate da architetti di fama internazionale proprio allo scopo di rafforzare, o meglio di costruire, un fattore identitario per ciascun quartiere ubicato nel settore orientale della città. Partendo quindi dal generale si arriva a indagare una chiesa e un quartiere che possono essere considerati un modello da seguire per tutta la periferia a ridosso del GRA: la chiesa giubilare di Dio Padre Misericordioso progettata da Richard Meier nel quartiere di Tor Tre Teste. La sequenzialità degli eventi che hanno contraddistinto il concorso per la progettazione della chiesa, la scelta della proposta di Richard Meier, la complessità del cantiere, l’analisi tecnica, stilistica e simbolica della realizzazione finale sono quindi analizzate nell’ambito del rapporto con il quartiere e del tentativo di realizzare (attraverso di essa un centro di attrazione per tutta la periferia.   The article analyses some significant parts of the urban tissue at the eastern periphery of Rome, using the interpretative methods inherent to history, society, urban programming and construction

  11. Multisource data assimilation in a Richards equation-based integrated hydrological model: a real-world application to an experimental hillslope

    2017-12-01

    Data assimilation is becoming increasingly popular in hydrological and earth system modeling, as it allows for direct integration of multisource observation data in modeling predictions and uncertainty reduction. For this reason, data assimilation has been recently the focus of much attention also for integrated surface-subsurface hydrological models, whereby multiple terrestrial compartments (e.g., snow cover, surface water, groundwater) are solved simultaneously, in an attempt to tackle environmental problems in a holistic approach. Recent examples include the joint assimilation of water table, soil moisture, and river discharge measurements in catchment models of coupled surface-subsurface flow using the ensemble Kalman filter (EnKF). Although the EnKF has been specifically developed to deal with nonlinear models, integrated hydrological models based on the Richards equation still represent a challenge, due to strong nonlinearities that may significantly affect the filter performance. Thus, more studies are needed to investigate the capabilities of EnKF to correct the system state and identify parameters in cases where the unsaturated zone dynamics are dominant. Here, the model CATHY (CATchment HYdrology) is applied to reproduce the hydrological dynamics observed in an experimental hillslope, equipped with tensiometers, water content reflectometer probes, and tipping bucket flow gages to monitor the hillslope response to a series of artificial rainfall events. We assimilate pressure head, soil moisture, and subsurface outflow with EnKF in a number of assimilation scenarios and discuss the challenges, issues, and tradeoffs arising from the assimilation of multisource data in a real-world test case, with particular focus on the capability of DA to update the subsurface parameters.

    Full Text Available Beyond the Soundtrack: Representing Music in Cinema (edited by Daniel Goldmark, Lawrence Kramer and Richard Leppert, Berkeley, University of California Press, 2007, viii-324 pp. offers sixteen essays of various authors about film music. These papers were presented in 2004 in a study congress at the University of Minnesota. In introducing the book, the editors assert an assumption, today broadly accepted: indeed they affirm, that music has traditionally been regarded as a subordinate element in cinematographic text: film music literature still has a marginal position in the much larger field of film studies which focuses on image, narrative, film history. In this theoretical and historiographic context, the expression “Beyond the Soundtrack” is meant to be more than a title: it is the manifesto of a conceptual shift. We can summarize this change in reconsidering the importance of film music, in order to understand a movie not only as a visual, but also as a musical medium. The change of paradigm brings renewed questions and completely new issues. If we abandon the assumption, at this point obsolete, that film music has a mere functional role, it will be necessary to ask not how to conceptualize the use of music in film, but rather how the film conceptualizes music: how films imagine music, how films represent music as an artistic and social phenomenon, and how films position music as an integral parts of a fictional world. Such questions aim to consider film music not as an atmospheric expedient, but «as an agent, a force, and an object engaged in ongoing negotiations with image, narrative, and context», as the editors assert at the very beginning of their book.

  13. Flinging a New Star: “Fire and Cloud” and “Bright and Morning Star” as Reflections of Richard Wright’s Changing Relationship with Communism

    Full Text Available Richard Wright's collection of short novella's, Uncle Tom's Children, was originally published in 1938; in 1940, after the success of Native Son, a new printing of the text appeared with two additions. The first was the introductory essay entitled "The Ethics of Living Jim Crow," which was written in 1937, and later served as part of Black Boy. The second was the novella "Bright and Morning Star." Michel Fabre notes that Harper's Magazine rejected this story, "but since it fit Party specifications even better than had the four previous stories, New Masses published it as part of a special literary supplement on May 10, [1938]" (164 . In fact, perhaps because New Masses originally published the final story, critical attention to the revised edition of book almost exclusively posits that the 1940 edition reflects Wright's commitment to Communism at the time. However, several of Wright's other writings-including the introductory essay to the 1940 edition, "The Ethics of Living Jim Crow;" "Blue print for Negro Writing," first published in New Challenge in the fall of 1937; "I Tried to be a Communist," first published in Atlantic Monthly in August and September 1944; and his responses to the Communist party's review of Native Son in 1940-also indicate that his focus in the late 1930s was more on the development of an individual black consciousness than on advancing the causes of the Communist party. By juxtaposing the final two stories, "Fire and Cloud" and "Bright and Morning Star," and considering them in terms of the other writings indicated above, I argue that the 1940 edition of Uncle Tom's Children (with the two additions demonstrates Wright's growing ambivalence with the Communist Party between the years of 1937 and 1940.

Nonsystematic review of the Madrid newspaper Gaceta de Madrid y Diario curioso, erudito, económico y comercial (Madrid Gazette, curious, erudite, financial and commercial) between 1759 and 1790. Review of the medical literature of the 18th century preserved in the Fondo Antiguo of the Biblioteca Histórica of Universidad Complutense de Madrid (Historical Resource of the Historical Library of the Complutense University of Madrid). A Google search of «Charles Richard de Beauregard». Charles de Beauregard focused his professional work mainly on the treatment of the urethral sequela of blennorrhagia, phimosis and paraphimosis. He introduced to 18th century Spanish society (with purported originality and clear commercial interests) therapeutic methods based on lead acetate that had already been developed in France by Thomas Goulard. The urethral sequela of diseases such as blennorrhagic urethritis, stenotic phimosis and paraphimosis were highly prevalent in 18th century Madrid and required complex solutions for the practice of urology of that era. Charles de Beauregard introduced innovative but not original treatments that were invasive but not bloody and that provided him with fame and social prestige. He advertised his professional activity and marketed his therapeutic products through advertisements submitted to the daily press (Madrid Gazette, Gaceta de Madrid). Copyright © 2015 AEU.

    Full Text Available Abstract – This paper will analyze the ‘historical’ novel Gould’s Book of Fish (2001 by the Tasmanian writer Richard Flanagan with the aim of reflecting upon the power of the creative word as a means to forge reality, shape identities, mask or unmask truths, and also to prefigure a different, alternative world order based on commonly negotiated and thus shared values. The postmodernist revisiting of the traditional genre of the historical novel does not compromise the postcolonial commitment of the writer: Flanagan’s incursions into the Australian colonial past are informed by his concern for urgent social and political causes which has characterized his unswerving fight against all systems of inequality and exploitation. In his novel, the subversion of the linear causal relation of events which calls into question the truthfulness and objectivity of history, together with the foregrounded metanarrative reflection on the art of writing, contribute to the revisiting and re-discussing of the myth of progress and the cult of rationality at the very roots of Western civilization and of its imperialistic enterprise. Flanagan’s ‘anti-historical’ historical novel tackles urgent questions about modernity interrogating the founding narratives of the Australian national identity, in order to explore the uncontrollable and shifting areas of the contemporary ‘transnation’ in which the traditional categories shaping subjectivities are disrupted. As the paper will demonstrate, the writer digs into the past of his nation not simply in order to unravel its hidden histories but to detect the profound, inextricable interconnections with the present across different times and spaces. Feelings and experiences that exist above and beyond historical contingencies and cultural differences represent the writer’s privileged area of investigation as they trespass upon conventional and artificial boundaries revealing what it is that makes us all

    Full Text Available We used the mitochondria DNA COI (cytochrome c oxidase subunit I sequence as a genetic marker to analyze the population genetic structure of two species of freshwater copepods, Neodiaptomus schmackeri (Poppe and Richard, 1892 and Mongolodiaptomus birulai (Rylov, 1922 from Taiwan. Four populations with 51 individuals of N. schmackeri and five populations with 65 individuals of M. birulai were included. We compared the nucleotide sequences of a 635-bp fragment of the COI gene of N. schmackeri and a 655-bp fragment of the COI gene of M. birulai, and eight and 14 unique haplotypes were recorded, respectively. Tseng-Wen reservoir and Wu-San-Tao reservoir are linked by a channel, and the gene flow between them was unrestricted (Fst = 0.058; Nm = 4.04; Fst, population differentiation parameter; Nm, the number of succesfull migrants per generation; the gene flow between all other populations of both species was restricted (Fst = 0.4–0.99; Nm = 0–0.37. Based on the COI gene diversification pattern, we suggest that most populations of N. schmackeri and M. birulai are isolated from each other. According to the neighbor-joining tree and the minimum spanning network (MSN, the species have similar metapopulation genetic structures. Genetic distance was not found to be correlated with geographical distance. The genetic diversification pattern was not shown to be comparable with geographical isolation owing to long-distance separation. The genetic structure of the present populations may result from serial extinction and redistribution of the populations formed in each reservoir relative to time. Human activity in the reservoirs with regards to water resource management and the fishery industry also exerts an effect on population redistribution.

    Full Text Available Este ensaio defende que o pensamento pós-analítico e pós-filosófico de Richard Rorty pode assumir uma função – de caráter profilático – muito interessante no âmbito dos estudos literários acadêmicos e na crítica literária em geral: suas reflexões críticas funcionam como uma advertência contra certas pretensões cientificistas da filosofia e, por consequência, das teorias literárias em geral. Os variados usos e objetivos da linguagemhumana em atos interpretativos – como na crítica literária – extrapolam a noção moderna de verdade como correspondência; o objetivo da crítica não é, pois, "a verdade", mas simplesmente continuar e enriquecer a grande e interminável conversação que é a cultura humana. A crítica só pode dizer “verdades” se entendermos essa palavra numa acepção humanístico-pragmática e não, como faz a filosofia racionalista tradicional, entendendo a verdade como certeza e como correspondência. Para o neopragmatista, devemos abandonar de uma vez por todas a busca por uma teoria geral da representação ou por uma teoria geral da linguagem; da mesma forma, transladando essa concepção ao âmbito literário, também deveríamos desobrigar-nos das sucessivas tentativas de criar uma teoria geral exclusivista da interpretação e da crítica literárias, ou da busca de uma metodologia monista e definitiva: a crítica é uma atividade plural e que atende a diversas demandas e objetivos

  4. The "dirty weather" diaries of Reverend Richard Davis: insights about early colonial-era meteorology and climate variability for northern New Zealand, 1839-1851

    2016-03-01

    Reverend Richard Davis (1790-1863) was a colonial-era missionary stationed in the Far North of New Zealand who was a key figure in the early efforts of the Church Mission Society. He kept meticulous meteorological records for the early settlements of Waimate North and Kaikohe, and his observations are preserved in a two-volume set in the Sir George Grey Special Collections in the Auckland Central Library. The Davis diary volumes are significant because they constitute some of the earliest land-based meteorological measurements that were continually chronicled for New Zealand. The diary measurements cover nine years within the 1839-1851 time span that are broken into two parts: 1839-1844 and 1848-1851. Davis' meteorological recordings include daily 9 a.m. and noon temperatures and midday pressure measurements. Qualitative comments in the diary note prevailing wind flow, wind strength, cloud cover, climate variability impacts, bio-indicators suggestive of drought, and notes on extreme weather events. "Dirty weather" comments scattered throughout the diary describe disturbed conditions with strong winds and driving rainfall. The Davis diary entries coincide with the end of the Little Ice Age (LIA) and they indicate southerly and westerly circulation influences and cooler winter temperatures were more frequent than today. A comparison of climate field reconstructions derived from the Davis diary data and tree-ring-based winter temperature reconstructions are supported by tropical coral palaeotemperature evidence. Davis' pressure measurements were corroborated using ship log data from vessels associated with iconic Antarctic exploration voyages that were anchored in the Bay of Islands, and suggest the pressure series he recorded are robust and can be used as "station data". The Reverend Davis meteorological data are expected to make a significant contribution to the Atmospheric Circulation Reconstructions across the Earth (ACRE) project, which feeds the major data

    Full Text Available It is usually said that the memory of the war period had been completely reversed in the former Soviet borderlands since the collapse of the USSR, turning former “traitors” into heroes or victims. However, attempts to set up a new approach of the Nazi occupation and collaboration are rooted in the “Thaw” period. I remember everything, Richard – dealing with the Latvian legion, started to be considered in 1957. That coincided both with the massive return of the Latvian deportees from Siberia, and with a renewal of trials against war criminals. Produced only in 1966, the film reflected the social tensions going along with the sensitive topic, and presented a point of view far more nuanced than the official figure of the “Latvian traitor” imposed during the Stalinist period. Based on interviews, archival material and film analysis, this article aims at understanding through the film-making process the connection between the deep changes of the political meaning of the war period, and the social composition of film production.

    Full Text Available Abstract This study examines the concept of crafting which means becoming an expert in an activity. Specializing in a field, in order to facilitate the life, backs as early as the first human settlements in human history. Crafting is a phenomenon in which the person makes the craft in the best possible way for its own goodness. However, it has been gone through some transformations since its formation. The history of crafting includes some milestones such as institution of crafting, its unification and its transformation after the Industrial Revolution. The most essential one of those transformations has been experienced after the Industrial Revolution and it has become difficult to define the crafting followingly. At the present time, crafting has been diminished to the status of a simple worker. In this work, which the historical transformation of crafting is held, It will be examined respectively: the historical roots of crafting, the social status of crafting, professional organizations that hold crafting altogether, the effects on crafting brought by new economic order of industrial revolution and the ideas of Richard Sennett on crafting in order to evaluate crafting in our present society. Hereby, I will try to reach the definitions of crafting that are able to address our today’s society by taking references from the roots of archaic crafting phenomenon.

    2015-01-01

    Sexuality has been defined a central feature of personal identity since the epoch of enlightenment and has gradually become a decisive issue also in societal and political terms. A major transfer from religion and religious institutions to medicine and medical experts and later on to neuropsychiatrists has to be underlined in the primary position to assess "normal" and "deviant" manifestations of sexuality. Richard Freiherr von Krafft-Ebing and Sigmund Freund play an eminent role in this "discourse on sexuality" (M. Foucault) during the nineteenth and beginning twentieth century on the way to modern sexology. Within this overarching context Krafft-Ebing's and Freud's theoretical conceptualizations of sexuality and perversion will be sketched and basic clinical and societal implications there out will be discussed.

    Full Text Available El trabajo se plantea como una reflexión sobre la dificultad actual para apreciar los valores, a menudo denostados, de los ya supuestamente lejanos arte y cultura del siglo XIX. De aquel rico mundo de referentes y asociaciones se destacan aquí las figuras del pintor realista Alma-Tadema, los arquitectos del Ring de Viena, con Semper como singular protagonista, y el músico Richard Wagner. Junto al análisis del complejo universo pictórico del artista holandés afincado en Inglaterra se presenta una reducida selección de obras arquitectónicas que culminan con los nuevos espacios para el arte más decisivamente alemán del XIX, la música.

  12. UNA NUEVA ALTERNATIVA NUMÉRICA PARA LA SOLUCIÓN DE LA ECUACIÓN UNIDIMENSIONAL DE RICHARDS: ESTUDIO DE DRENAJE E INFILTRACIÓN DE FLUIDOS EN LA ZONA NO SATURADA

    Full Text Available En el trabajo se comparan dos métodos numéricos para resolver el modelo unidimensional de infiltración y drenaje de agua en la zona no saturada en medios porosos, el cual es modelado respecto al contenido de humedad utilizando la ecuación no-lineal de Richards. El primer método está basado en el método clásico de Diferencias Finitas y el segundo en el método de Líneas combinado con el código DASSL para la solución de las ecuaciones diferenciales-algebraicas resultantes. Se muestra que el último método proporciona una vía numérica eficiente para la solución de problemas de EDPs que tienen un comportamiento singular de shock u ondas viajeras, como es el caso de la ecuación de Richard, los cuales se pueden resolver numéricamente con éxito sólo utilizando esquemas muy estables. Los métodos numéricos discutidos en el trabajo se aplican a dos tipos de suelos reales: Yolo Light Clay y Brindabella Silty Clay Loam, usando las propiedades hidráulicas referidas en Broadbridge y White [16]. Para validar el modelo, se comparan los perfiles de humedad con los resultados reportados por Warrick, Lomen e Islas [18].Igualmente, se demuestra con datos reales la ventaja de resolver numéricamente el comportamiento del flujo unidimensional en la zona no saturada de un medio poroso. Finalmente, el modelo propuesto y los resultados numéricos obtenidos posibilitan brindar un pronóstico sobre la utilización de recursos hídricos para el caso de riego en agricultura y también para el transporte de contaminantes.

    The study of Einstein's theory of general relativity experienced a renaissance beginning in the early 1960s. Prior to this resurgence of interest, general relativity was isolated from mainstream physics-admired for its elegance, perhaps, but only from a distance. The generation of students who risked their careers by entering this neglected field has now reached the age of festschrifts. In June of 2000, Caltech hosted ;Kipfest,; a conference in honor of Kip Thorne's 60th birthday. Thorne started graduate school at Princeton in 1962 and began research in general relativity under John Wheeler's guidance in the heady early days of the renaissance. Since then, he has played a prominent role in general relativity: as co-author of the influential textbook Gravitation, as a leader in research regarding astrophysical applications of Einstein's theory, and as a co-founder and chief advocate for the Laser Interferometer Gravitational Wave Observatory (LIGO), to mention a few aspects of his far-reaching work. ;Kipfest; included 14 speakers discussing fields to which Thorne has contributed. But the conference also reflected Thorne's long-standing commitment to communicating science to a general audience: Igor Novikov, Stephen Hawking, Timothy Ferris, and Alan Lightman gave popular talks at ;Kipfest,; with Thorne himself tricked into delivering a fifth. The Future of Spacetime gathers adaptations of these five lectures, along with a lengthy introductory essay by Richard Price.

    Dr. Eugene R. Tomer passed away on 2 July 2007 at his home in San Francisco, California. The cause of death was cancer. Tomer was a consulting applied mathematician with a wide range of interests in dynamical astronomy, electromagnetic theory for use in communications, and computational methods of applied mathematics. He was a member of AAS, and the Society for Applied and Industrial Mathematics [SIAM]. With K. H. Prendergast, he co-wrote the influential paper "Self-consistent Models of Elliptical Galaxies," published in the Astronomical Journal 75 (1970), 674-679. This paper has been cited over eighty times. Tomer was born on 13 June 1932. He earned the Ph.D. in Mathematics at the University of California-Berkeley in 1978 (title of dissertation: On the C*-algebra of the Hermite Operator). In 1996 he and A. F. Peterson wrote "Meeting the Challenges Presented by Computational Electromagnetics," a publication of the Naval Postgraduate School at Monterey, California. This writer met Eugene at the 1992 Annual SIAM meeting in Los Angeles in connection with the Activity Group on Orthogonal Polynomials and Special Functions, which the writer chaired at the time. Eugene volunteered to edit the Newsletter of the group, which he did from July 1992 to July 1995. Thanks to his skills and efforts, the Newsletter became a carefully edited, professional publication. Eugene not only organized a Problems Column, attracting questions in pure and applied mathematics, but he also designed the logo for the group. He gave much time and effort to this service, in an era when copy had to be physically assembled and mailed to SIAM Headquarters. Eventually he felt he had done what he could for the Activity Group. He told me that he hoped the Group would get seriously involved with applications such as in astronomy, physics, and sciences that use special function solutions of differential equations. During Tomer's editorship, we communicated mostly by e-mail, our homes being far apart. He was a good friend to the Group and to me, as much as one can be over a separation of thousands of miles. As well, Eugene was an active amateur radio operator, much appreciated by his local amateur radio community, with call sign WI6X. He left behind family, friends, and one son.

  10. Lanthanide Organophosphate Spiro Polymers: Synthesis, Structure, and Magnetocaloric Effect in the Gadolinium Polymer.

    2017-08-07

    Spirocyclic lanthanide organophosphate polymers, {[Ln(dipp)(dippH)(CH 3 OH)(H 2 O) 2 ](CH 3 OH) 2 } n [Ln = La (1), Ce (2), Pr (3), Nd (4), Sm (5), Eu (6), Gd (7), Tb (8), Dy (9), Ho (10), Er (11)], have been prepared from the reaction of Ln(NO 3 ) 3 ·xH 2 O with sterically hindered 2,6-diisopropylphenyl phosphate (dippH 2 ) using aqueous NaOH as the base. The one-dimensional chainlike lanthanide (III) organophosphate coordination polymers have been characterized with the aid of analytical and spectroscopic methods. The single crystal structure determination of polymers (2-5 and 7-11) reveals that in these compounds the hydrophobic organic groups of the phosphate provide a protective coating for the inorganic lanthanide phosphate polymeric chain. The encapsulation of inorganic lanthanide phosphate core, which has very low solubility product, within the organic groups assists in the facile crystallization of the polymers. The di- and monoanionic organophosphate ligands dipp 2- and dippH - display [2.111] and [2.110] binding modes, respectively, in 2-5 and 7. However, they exhibit only [2.110] binding mode in the case of 8-11. This results in the formation of two different types of polymers. While the lighter rare-earth metal ions in 2-5 and 7 display eight coordinate biaugmented trigonal prismatic geometry, the heavier rare-earth metal ions in 9-11 exhibit a seven coordinate capped trigonal prismatic environment. The Tb(III) ion in 8 displays distorted pentagonal bipyramidal geometry. Magnetic studies reveal the presence of weak antiferromagnetic interactions between the Ln(III) ions through the organophosphate ligand. The isotropic Gd(III) polymer 7 exhibits a maximum entropy change of 17.83 J kg -1 K -1 for a field change of 7.0 T at 2.5 K, which is significant considering the high molecular weight of the organophosphate ligand. These polymers represent the first family of any structurally characterized rare-earth organophosphate polymers derived from monoesters of phosphoric acid.

    Full Text Available A series of novel substituted quinazolinone derivatives was synthesized and characterized by 1H NMR and LC–MS spectral techniques. The overall results of the antibacterial tests showed that these compounds had better bacteriostatic activity against Gram-positive bacteria than their parent compounds. Furthermore, compounds 5f, 6b and 6f showed potent activity against Enterococcus faecalis (ATCC 51299, with MIC values <0.2 μg/mL. Compounds 4e, 5g, 5e and 6c showed excellent activity, with MIC values <0.4 μg/mL. Gram-negative bacteria Escherichia coli (ATCC 35218 and Klebsiella (ATCC 700603 are more resistant to lower concentrations of the synthesized compounds. The anti-inflammatory activities of the synthesized compounds were evaluated using the Carrageenan-induced rat Paw oedema method and ibuprofen as a standard drug. Compounds 4a and 4b exhibited good activity. Additionally, docking stimulations were performed to position compounds 4e, 4g, 5e, 5f, 6a and 6f into the EGFR kinase domain and human oestrogen receptor active site to determine probable binding information. This study indicated that compounds 6a and 6f have significant binding activities of 58.36 and 57.67 kJ mol−1, respectively.

    The survival time and reproduction of female Daphnia pulex in solutions varying in pH have been observed. Dilute sodium hydroxide or sulfuric acid solutions were added to four different diluent waters: distilled water, aerated tap water, aerated and filtered tap water from an aquarium containing Dace minnows, and Mcintyre River water. D. Pulex (initially up to 72 hours old) survived for the duration of the experiment (32 hours) in river water within a pH range of 6.1 to 10.3; in aquarium water within a pH range of 4.3 to 10.4; only at pH 6.4 and pH 7.6 in distilled water; and in none of the solutions using aerated tap water. The dissolved oxygen content was measured at the beginning and end of every experiment and was found never to fall below 6.2 p.p.M. Those individuals which survived were cultured in the laboratory and parthenogenesis was observed at pH values between 7.0 and 8.7.

    Full Text Available A Review of: Trueswell, R. L. (1969. Some behavioral patterns of library users: The 80/20 rule. Wilson Library Bulletin, 43(5, 458-461. Objective – To demonstrate the relationship between library circulation and the percent of a library's holdings satisfying circulation. Design – Retrospective cohort study of library circulation data. Setting – Cambridge and Northampton, Massachusetts, United States of America. Subjects – The users of the monographic holdings of the Air Force Cambridge Research Laboratory Library and the Forbes Public Library. Methods – Trueswell compiled circulation data from the Air Force Cambridge Research Laboratory Library over a period of 5 years, ostensibly from 1964-1969. Additionally, he gathered circulation data from Forbes Public Library. Trueswell compared each respective collection of data against the entire holdings of each library, after which he converted each measure to a percentage of the whole. Main Result – Based on the collected data, Trueswell found that the percentages of both libraries’ holdings that satisfy circulation follow a power law distribution. He compared this with a previous study measuring journal circulation at a Health Sciences Library that exhibited the same pattern. He stated that these similar distributions demonstrated the "80/20 Rule." The distribution is such that any given percent of circulation will provide the percent of a library’s circulating holdings necessary to satisfy it. Additionally, Trueswell found that 75 percent of current circulation had circulated at least once within the preceding year. Conclusion – The findings have implications for core collection development, purchasing multiple copies of a given title, determining the optimal size of a library's collection, and weeding. Trueswell also submits the idea of developing regional interlibrary loan centers for books that do not circulate often, as a cost saving measure for most libraries.

    2014-12-01

    The two-species population dynamics model is the simplest paradigm of inter- and intra-species interaction. Here, we present a generalized Lotka-Volterra model with intraspecific competition, which retrieves as particular cases, some well-known models. The generalization parameter is related to the species habitat dimensionality and their interaction range. Contrary to standard models, the species coupling parameters are general, not restricted to non-negative values. Therefore, they may represent different ecological regimes, which are derived from the asymptotic solution stability analysis and are represented in a phase diagram. In this diagram, we have identified a forbidden region in the mutualism regime, and a survival/extinction transition with dependence on initial conditions for the competition regime. Also, we shed light on two types of predation and competition: weak, if there are species coexistence, or strong, if at least one species is extinguished.

    The leaching potential of three insecticides (spirodiclofen, spiromesifen, and spirotetramat) was assessed using disturbed soil columns. Small quantities of spirodiclofen and spiromesifen were detected in leachate fraction, while spirotetramat residues were not found in the leachates. In addition, the transformation products (enol derivatives) are relatively more mobile than the parent compounds and may leach into groundwater. Moreover, the use of disinfection soil techniques (solarization and biosolarization) to enhance their degradation rates in soil was investigated. The results show that both practices achieved a reduction in the number of juvenile nematodes, enhancing in a parallel way degradation rates of the insecticides and their enol derivatives as compared with the non-disinfected soil. This behavior can be mainly attributed to the increase in soil temperature and changes in microbial activity. All insecticides showed similar behavior under solarization and biosolarization conditions. As a consequence, both agronomic techniques could be considered as suitable strategies for detoxification of soils polluted with the studied pesticides.

    Novel mono and bis spiropyrrolidine derivatives were synthesized via an efficient ionic liquid mediated, 1,3-dipolar cycloaddition methodology and evaluated in vitro for their AChE and BChE inhibitory activities in search for potent cholinesterase enzyme inhibitors. Most of the synthesized compounds displayed remarkable AChE inhibitory activities with IC50 values ranging from 1.68 to 21.85 μM, wherein compounds 8d and 8j were found to be most active inhibitors against AChE and BChE with IC50 values of 1.68 and 2.75 μM, respectively. Molecular modeling simulation on Torpedo californica AChE and human BChE receptors, showed good correlation between IC50 values and binding interaction template of the most active inhibitors docked into the active site of their relevant enzymes.

    A number of novel heterocyclic chalcone derivatives can be synthesized by thermal and microwave tools. Treatment of 4-(4-Acetylamino- and/or 4-bromo-phenyl)-4-oxobut-2-enoic acids with hydrogen peroxide in alkaline medium were afforded oxirane derivatives 2. Reaction of the epoxide 2 with 2-amino-5-aryl-1,3,4-thiadiazole derivatives yielded chalcone of imidazo[2,1-b]thiadiazole derivative 4 via two thermal routes. In one pot reaction of 4-bromoacetophenone, diethyloxalate, and 2-amino-5-aryl-1,3,4-thiadiazole derivatives in MW irradiation (W 250 and T 150 °C) under eco-friendly conditions afforded an unsuitable yield of the desired chalcone 4d. The chalcone derivatives 4 were used as a key starting material to synthesize some new spiroheterocyclic compounds via Michael and aza-Michael adducts. The chalcone 4f was similar to the aryl-oxo-vinylamide derivatives for the inhibition of tyrosine kinase and cancer cell growth. The electron-withdrawing substituents, such as halogens, and 2-amino-1,3,4-thiadiazole moeity decreasing the electron density, thereby decreasing the energy of HOMO, and the presence of imidazothiadiazole moiety should improve the antibacterial activity. Thus, the newly synthesized compounds were evaluated for their anti-bacterial activity against (ATCC 25923), (ATCC 10987), (ATCC 274,) and (SM514). The structure of the newly synthesized compounds was confirmed by elemental analysis and spectroscopic data.

Obwohl die offensiven Netzkriegskapazitäten Nordkoreas verhältnismäßig gering sind, präsentiert sich die virtuelle Kampfkraft des nordkoreanischen Regimes in Bestform. Die Verwundbarkeit ziviler Systeme, insbesondere der Energieversorgung, muss in direkter Korrelation mit deren Anknüpfung an das Internet betrachtet werden. The more broadly connected a country’s infrastructure and energy distribution, the greater its vulnerability in the event of a cyber war. Measuring this virtual fighting power is based on three factors: offensive and defensive strength, as well as dependency on the Internet. As a superpower, the USA has the greatest virtual offensive strength available. At the same time, the nation is most susceptible to cyber attacks and therefore most vulnerable. By contrast, North Korea’s offensive cyber fighting power is relatively small, but its overall cyber war capabilities are cutting-edge. The vulnerability of civil systems, especially power supply, must be viewed in direct correlation to their connection to the Internet.

    2006-06-01

    In a recent issue of this journal, Kocsis reviewed the criminal profiling research that he and his colleagues have conducted during the past 4 years. Their research examines the correlates of profile accuracy with respect to the skills of the individual constructing the profile, and it has led Kocsis to draw conclusions that are important to the profiling field. In this article, the authors review the contributions of the Kocsis studies and critique their methodological and conceptual foundations. The authors raise a number of concerns and argue that data from the Kocsis studies fail to support many of the conclusions presented in his recent review. The authors present evidence in support of their assertions and provide recommendations that will allow future research in the area to generate data that are more meaningful and generalizable.

    Full Text Available Rorty invites us to abandon the belief that moral foundationalism of a universalist nature is useful for the moral progress of our societies. Instead, he suggests that post-modern secular liberalism and solidarity, understood as a local identification process and not as a universally binding principle, should be the axes of such progress. The present article will 1 clarify the redescription of solidarity made by Rorty, 2 show how such contingent redescription ends up being more useful for the attaining of solidarity that the foundationalist view, and 3 suggest an interpretation from which the self-empowerment between his notion of liberalism and the redescription of the concept of solidarity can be made evident.

    2013-01-01

    In carrying out its mission to ensure the safe use of radioactive materials for beneficial civilian purposes while protecting people and the environment, the U.S. Nuclear Regulatory Commission (NRC) adheres to its Principles of Good Regulation. The Principles-Independence, Openness, Efficiency, Clarity, and Reliability-apply to the agency as a whole in its decision-making and to the individual conduct of NRC employees. This paper describes the application of the Principles in a real-life staff activity, a guidance document used in the NRC's low-level radioactive waste (LLW) program, the Concentration Averaging and Encapsulation Branch Technical Position (CA BTP). The staff's process to revise the document, as well as the final content of the document, were influenced by following the Principles. For example, consistent with the Openness Principle, the staff conducted a number of outreach activities and received many comments on three drafts of the document. Stakeholder comments affected the final staff positions in some cases. The revised CA BTP, once implemented, is expected to improve management and disposal of LLW in the United States. Its positions have an improved nexus to health and safety; are more performance-based than previously, thus providing licensees with options for how they achieve the required outcome of protecting an inadvertent human intruder into a disposal facility; and provide for disposal of more sealed radioactive sources, which are a potential threat to national security.

    Full Text Available This essay examines the  impact of the Mexican Revolution in business activities by focusing on a study of the Compañía Con­structora  Richardson,  an  enterprise  which was  to  provide hidraulic infrastructure in the Yaqui Valley during the  revolu­tion. The company faced numerous obstacles caused by the rev­olution: conflicts with yaquis in the Yaqui Valley itself, and insti­tutional changes of federal and local governments, including the loss of its concession because of disagreement with the gov­ernment with regard to the new fiscal system. This study shows that, while presidents expressed different views about private en­terprises involved in hidraulic construction, public administra­tive organizations gradually consolidated coherent policies with regard to water management and water resources.

  7. The Richard C. Schneider Lecture. New dimensions of neurosurgery in the realm of high technology: possibilities, practicalities, realities.

    Science.gov (United States)

    Apuzzo, M L

    1996-04-01

    Fueled by a buoyant economy, popular attitudes and demands, and parallel progress in transferable technical and biological areas, neurosurgery has enjoyed a remarkable quarter of a century of progress. Developmental trends in the discipline have included the following: 1) a refinement of preoperative definition of the structural substrate, 2) miniaturization of operative corridors, 3) reduction of operative trauma, 4) increased effectiveness at the target site, and 5) incorporation of improved technical adjuvants and physical operative tools into treatment protocols. In particular, the computer has become a formidable ally in diagnostic and surgical events. Trends in technical development indicate that we are entering an exciting era of advanced surgery of the human cerebrum, which is heralded by the following: 1) current developments in areas of imaging, sensors, and visualization; 2) new devices for localization and navigation; 3) new capabilities for action at the target point; and 4) innovative concepts related to advanced operative venues. Imaging has provided structurally based surgical maps, which now are being given the new dimension of function in complex and integrated formats for preoperative planning and intraoperative tactical direction. Cerebral localization and navigation based on these advances promise to provide further refinement to the field of stereotactic neurosurgery, as linked systems are superseded by more flexible nonlinked methodologies in functionally defined volume-oriented navigational databases. Target point action now includes not only ablative capabilities through micro-operative methods and the use of stereotactically directed high-energy forms but also the emergence of restorative capabilities through applications of principles of genetic engineering in the areas of molecular and cellular neurosurgery. Complex, dedicated, and self-contained operative venues will be required to optimize the emergence and development of these computer-oriented micro/stereotactic capabilities, which appear to be unavoidably required as locales for the practice and development of virtual reality-based stations for operative rehearsal, simulation, training, and, ultimately, enhancement of operative events through robotic interfaces. Primary impetus for progress has relied upon new combinations of technologies, disciplines, and industries. Philosophical and practical problems include the spectrum of availability of these methods to the population at large, the training of individuals to properly administer these methods, defining the acceptable envelope of expertise, and maintaining suitable delivery and progress while containing spiraling costs. Advanced neurological surgery and the use and development of high-technology adjuvants require a robust economy that has a populace willing to invest in the luxury of such developments. The current socioeconomic situation is fragile from the standpoint of both economics and attitudes of the patients and health care providers, with diversion of economic resources, redistribution of funding bases, modification of patient referrals, practice styles, and service attitudes undermining progress. Economic pressures have brought high-technology methods under great scrutiny regarding their effectiveness and cost-effectiveness. Reform proposals have specifically targeted technology-oriented services, and the Office of Technology Assessment has recommended increasing the use of managed care providers who look to information on cost-effectiveness and clinical practice guidelines to establish efficient management strategies and issue "report cards." Although the premise is laudable and "gimmickry" needs to be identified, it might be argued that such scrutiny and control might be overbearing and overused, impeding appropriate delivery and progress.

  11. An analysis of Richard Prince's "Lake Resort Nurse": using an image to expose and critically reflect on stereotypes in nursing.

    Science.gov (United States)

    Holmes, Vicki C

    2012-01-01

    Our interactions with images, created and viewed within contexts, are a significant means through which we construct and interpret our values and beliefs. Nurses' efforts at monitoring images to encourage accurate portrayals of nurses' work have had little influence on the way nurses are represented or the inherent ability of images to shape perceptions of nurses' work. One explanation for this lack of influence is that viewers do not closely attend to the ways in which we make meaning of everyday images. This inattention creates passive viewers, vulnerable to and more likely to internalize messages (G. Dines & J. Humez, 2011). Misunderstandings about nursing leave nurses vulnerable to contexts and influence the outcomes of at least 2 issues, the nursing shortage and the provision of quality care. Prince, in his painting "Lake Resort Nurse," utilizes the artistic strategies of expressionism, appropriation, and reflexivity to expose stereotypes and provides an opportunity for reflection on the potential impact these stereotypes have on the profession. He provides a means through which we can recognize that images are significant contributors to how understandings of nursing and nurses are shaped. New understandings of nursing, gained through reflection and dialog, subsequently influences perceptions of the value of nurses' work and their contribution to health care.

    Two novel second ligands, 9,9-Di-(4-methoxyphenyl)-9-H-4,5-' (OMe-Spiro-DF) and 9,9-Di-(2-(4-(4-butyloxy)phenyl)-5-phenyl-1,3,4-oxadiazolyl)-phenyl-9-H-4, 5-Diazafluorene (OXD-Spiro-DF), were successfully prepared. Europium complexes, Eu(DBM) 3 (OMe-Spiro-DF) and Eu(DBM) 3 (OXD-Spiro-DF) (DBM=dibenzolylmethane) based on the two ligands were designed and synthesized. For a double-layer device with configuration of indium tin oxide (ITO)/N, N'-diphenyl-N,N'-bis(3-methylphenyl)-1,1'-biphenyl-4,4'-diamine (TPD)/Eu(DBM) 3 (OXD-Spiro-DF) or Eu(DBM) 3 (OMe-Spiro-DF)/Mg/Ag, compared with the device based on complex Eu(DBM) 3 (OMe-Spiro-DF), the brightness and electroluminescent (EL) efficiency of device based on complex Eu(DBM) 3 (OXD-Spiro-DF) with oxadiazole-functionalized ligand OXD-Spiro-DF are significantly improved due to the improvement of electron-transporting ability. A maximum brightness of 154 cd/m 2 was obtained at 17 V in the complex Eu(DBM) 3 (OXD-Spiro-DF), about four times brighter than the corresponding complex Eu(DBM) 3 (OMe-Spiro-DF)

    α-Amino acid derived benzimidazole-linked rhodamines have been synthesized, and their metal ion sensing properties have been evaluated. Experimentally, l-valine- and l-phenylglycine-derived benzimidazole-based rhodamines 1 and 2 selectively recognize Al 3+ ion in aqueous CH 3 CN (CH 3 CN/H 2 O 4/1 v/v, 10 mM tris HCl buffer, pH 7.0) over the other cations by exhibiting color and "turn-on" emission changes. In contrast, glycine-derived benzimidazole 3 remains silent in the recognition event and emphasizes the role of α-substitution of amino acid undertaken in the design. The fact has been addressed on the basis of the single-crystal X-ray structures and theoretical calculations. Moreover, pink 1·Al 3+ and 2·Al 3+ ensembles selectively sensed F - ions over other halides through a discharge of color. Importantly, compounds 1 and 2 are cell permeable and have been used as imaging reagents for the detection of Al 3+ uptake in human lung carcinoma cell line A549.

    2016-01-01

    Full Text Available This paper focuses on computations technique within the framework of the TD-DFT theory for studying the relationship between structure-properties of reversible conversion of photochromic materials. Specifically, we report on 1′,3′-dihydro-8-methoxy-1′,3′,3′-trimethyl-6-nitrospiro[2H-1-benzopyran-2,2′-(2H-indole] (SP and its isomers. TD-DFT calculated UV-Vis electronic spectra of the closed and open isomers of this photochromic material are in excellent agreement with the experimental results. Moreover, this paper reports on the results of theoretical investigations of reactivity indices that may govern the conversion between spiropyrans and its isomers. In addition, the solvent and rigidity of the medium significantly control the thermal bleaching of the photogenerated colored isomers and hence the switch ability pattern of the photochromic material. The effect of molecular structure computed by DFT in gas-phase and solvents on Cspiro-O bond length has been shown to correlate with photochromic properties. For this compound, DFT optimized geometry could be used to predict photochromism. Furthermore, in an attempt to predict the driving force for MC → SP, this work explores, for the first time, profitable exploitation of the calculated and visualized mapped electrostatic potential energy surfaces (ESP map. Interestingly, it seems that the electrostatic potential forces over the molecular fragments govern spirobond rupture/closure reactions. Thermodynamically, all-trans-colored isomer (CTT is the most stable merocyanine-like form.

    Hemoparasites are vector-borne parasites that infect wild carnivores worldwide. Since data on hemoparasite infections in Nasua nasua from Brazil are lacking, the aim of this study was to investigate the occurrence of hemoparasites and ectoparasites in N. nasua from different areas of Brazil. Blood samples and ectoparasites from 83 N. nasua were collected in Botucatu, Palmital, and São Paulo municipalities. Samples were screened via microscopy and molecular methods to detect hemoparasites. Tissues from two N. nasua were obtained for histopathological and molecular analyses. All 83 samples were negative for piroplasms on morphological and molecular examination. Thin blood smears of nine animals were positive for Hepatozoon gamonts. The gamonts shared morphological characteristics of Hepatozoon procyonis. Meronts were detected in the liver and spleen tissue of one animal. Twenty-one blood samples and four tissue samples were PCR positive for Hepatozoon sp. The sequences obtained were 97% identical to those of Hepatozoon felis, Hepatozoon ursi, and Hepatozoon sp. Based on searches for similarity and morphology, we identified the sequences as belonging to H. procyonis. This study provides epidemiological data on hemoparasite infections and redescribe H. procyonis based on morphological, morphometrical, and molecular analyses.

    Full Text Available De comunidade à metrópole: a biografia de São Paulo , was first published in 1954 and then re published in 1970 as Formação histórica de São Paulo: de comunidade à metrópole . Written by a young US researcher fascinated by Latin America, this material was originally submitted as his PhD thesis at Columbia University in 1952. Since then, Rich - ard Morse’s (1922-2001 work has come a long way and is now considered a primary reference in the history of urban development of São Paulo. This article briefly recovers the reader’s response when Morse’s research was first published, and how it ensured the book’s importance in the Brazilian historiography. The aim is to draw a parallel trajectory of the book and its author – the young researcher at Columbia who became a professor of Latin American History at Yale – and to discuss the meanings regarding its importance in São Paulo’s historiography as well as its contribution to a better understanding of the city.

    The United States Deep Submergence Facility is in the process of obtaining support for construction of a new manned submersible as a replacement for DSV Alvin. A new 6000+ meter manned submersible will provide U.S. scientists with access to an additional 35 per cent of the ocean floor including some currently unreachable portions of the U.S. EEZ. Researchers will have a vehicle designed for the missions currently conducted and those of the foreseeable future having the power and endurance to maximize the usefulness of available research time. They will have a more comfortable vehicle with a larger interior, improved viewport placement, greater battery capacity, and generally better able to handle the burgeoning scientific equipment requirements. Lastly they will have a vehicle that builds on the experience and improvements of 35 years that have made ALVIN the most successful research submersible in the world. The adaptability of the National Deep Submergence Facility (NDSF) to a wide variety of science needs is its strength, but this complexity can also confuse and intimidate new users. The NDSF maintains strong science liaison services and provides potential users with assistance throughout the process of cruise planning, proposal preparation, and execution of field programs. Procedures for gaining access to these vehicles are not difficult and potential users are assisted both directly by the NDSF personnel and also through a user group of scientists dedicated to providing the benefit of their experience. A successful mechanism for obtaining feedback between users and operator has been established through the Deep Submergence Science Committee (a UNOLS oversight committee) and the science community. Programs are selected for funding on a competitive basis through various federal funding agencies by standard agency review processes. DSV ALVIN and its support ship R/V ATLANTIS are owned by the U.S. Navy and operated under charter agreement with the Office of Naval Research. Operation of the NDSF remotely operated vehicle (ROV) assets can be arranged in a fly-away mode on appropriate vessels within the UNOLS fleet or on commercial vessels or foreign research vessels provided they are suitably equipped. Scheduling of the R/V ATLANTIS is arranged through UNOLS, as is the use of the ROVs on UNOLS ships. Coordination between funding agencies and the UNOLS scheduling process strives to provide the users with the optimal scheduling of the assets in a given year. Requests for at-sea use of these assets remain strong for the foreseeable future.

    In this work, well-soluble tris(pentafluorophenyl)borane (BCF) is introduced for the first time into 2,2',7,7'-tetrakis(N,N'-di-p-methoxyphenylamine)-9,9'-spirobifluorene (spiro-OMeTAD) as a p-dopant. The conductivity of spiro-OMeTAD films is dramatically enhanced. When the BCF-doped spiro-OMeTAD film is used as a hole-transport layer (HTL) in perovskite solar cells (PSCs), nearly double increase in power conversion efficiency (PCE) is obtained compared to that of the PSCs based on a pristine spiro-OMeTAD HTL. By the introduction of lithium bis(trifluoromethanesulfonyl)imide and 4-tert-butylpyridine into the BCF-doped spiro-OMeTAD film, the conductivity of spiro-OMeTAD film can be further enhanced, and an optimum PCE of 14.65% is obtained. In addition, the average efficiency of the device and the reproducibility of BCF-based PSCs are better than those of FK209-based PSCs. The working mechanism of the BCF doping effect on spiro-OMeTAD is studied in detail. The strong electron-accepting ability, excellent solubility in common organic solvents, and the low cost make BCF a very attractive p-type dopant for spiro-OMeTAD.

  5. Reply to “Statistical evaluation of the VAN Method using the historic earthquake catalog in Greece,” by Richard L. Aceves, Stephen K. Park and David J. Strauss

    Science.gov (United States)

    Varotsos, P.; Lazaridou, M.

    The pioneering calculation by Aceves et al. [1996] shed light on the main question of this debate, i.e., on whether “VAN predictions can be ascribed to chance.” Aceves et al. [1996] conclude that “the VAN method has resulted in a significantly higher prediction rate than randomly sampling a PDF (probability density function) map generated from a 25 year history of earthquakes.” After investigating the totality of VAN predictions issued during the period 1987-1989, Aceves et al. [1996] found: “The prediction rate for the VAN method clearly exceeds that from the random model at all time lags between 5-22 days. At a 5 day time lag, the VAN prediction rate of 35.7% has a P-value of less than 0.06%. This means that a random model does as well as does the VAN method less than 0.06% of the time. At 22 days, the prediction rate of 67.9% has a P-value of less than 0.07%.” These conclusions basically coincide with those of Hamada [1993] although Aceves et al. [1996] followed different procedures. They are also in fundamental agreement with the results of Honkura and Tanaka [1996]. Another important conclusion of Aceves et al. [1996] is that, after declustering the earthquake catalog and prediction list from aftershocks, “VAN method is still formally significant.”

    This report is a feasibility study for a biogas production unit adapted to a farm in Champtauroz in Switzerland, and a dual purpose power plant generating thermal and electric energy from the biogas according to the energy demand of the cheese factory attached to the farm. Typically 5*10{sup 5} m{sup 3} per year of biogas should be extracted from the manure of around 1,500 farm animals. The methane would be produced by a continuously operated digestor. The energy demand of the cheese factory, mainly thermal energy for the goat milk transformation process and electric power for the milk refrigeration, is measured in details and its annual profile is estimated. This demand is practically independent from the outdoor temperature as long as this temperature is higher than 10 {sup o}C. The report also includes a cost estimate for the whole project, functional schematics of the biogas production unit and of the power plant, and several diagrams displaying the heat and electric power demands of the cheese factory as a function of parameters like the cheese production and the quantity of refrigerated milk.

    Wake Vortex Turbulence is the turbulence generated by an aircraft in flight. This turbulence is created by vortices at the tips of the wing that may decay slowly and persist for several minutes after creation. These vortices and turbulence are hazardous to other aircraft in the vicinity. The strength, formation and lifetime of the turbulence and vortices are effected by many things including the weather. Here we present the final results of the pilot project to investigation of low level wind fields generated by the Weather Research and Forecasting Model and an analysis of historical data. The findings from the historical data and the data simulations were used as inputs for the computational fluid dynamics model (OpenFoam) to show that the vortices could be simulated using OpenFoam. Presented here are the updated results from a research grant, ``A Pilot Project to Investigate Wake Vortex Patterns and Weather Patterns at the Atlantic City Airport by the Stockton University and the FAA''.

The Second Edition features a wealth of additional material including new chapters on time delay estimation, direction finding techniques, and the MUSIC algorithm. This practical resource provides you with critical design information on geolocation algorithms, and establishes the fundamentals of existing algorithms as a launch point for further algorithm development. You gain an in-depth understanding of key target location methods that you can effectively apply to your work in the field. You discover triangulation algorithms that offer a highly efficient way to geolocate targets when the real estate on the sensor systems is adequate to support an antenna array. The book also presents quadratic geolocation techniques that can be implemented with extremely modest antennas — frequently a single dipole or monopole. Moreover, this authoritative volume details methods for geolocating the source of high frequency signals with a single sensor site.

It has become unacceptable for those responsible for corporate governance to claim, "I didn't know". Corporate Fraud and Internal Control focuses on the appropriateness of the design of the system of internal controls in fraud risk mitigation, as well as the mechanisms to ensure effective implementation and monitoring on an ongoing basis. 

  10. Introduction: commentaries and author's response to "The rise and fall of the autochthonous self: from Italian Renaissance Art and Shakespeare to Hediegger, Lacan, and Intersubjectivism" by Richard D. Chessick.

    Science.gov (United States)

    Leffert, Mark; Schwartz, Scott C; Chessick, Richard D

    2011-01-01

    This article addresses the unresolved question of the existence of a private core autochthonous self, as it has been described by Winnicott, Modell, and others. The postmodern version of the self has eliminated this concept entirely, relegating the self to a changing and unstable display, or regarding it as totally chaotic, or even an illusion. The question is raised whether by returning to the origins of this notion of a private self and then tracing its apparent dissolution it might be possible to discover some evidence that it still exists. The methodology used is that of obtaining knowledge directly through the arts and the claim is made that because empirical science has clamored to be the only source of knowledge, we have lost what could be obtained by direct intuitive seeing and experiencing the works of creative geniuses. To explore the rise of the autochthonous self this article provides an examination of the shift from Gothic art to Italian Renaissance art, a time which engendered the origin of "man" with his or her elusive private individual self that then became expressed in changing works of art. As this spread north, Shakespeare appeared and similarly invented and illustrated in his characters the private individual self, a concept not appreciated or recognized before the Renaissance. But as science arose and Western civilization began to decline, a corresponding disillusionment with "man" took place. The self began to be viewed as solely a social construction with no core except perhaps a genetic endowment. This was accompanied by a reduction in the concept of the human as a valuable and precious living being and was replaced by regarding the human as an object of control and exploitation. After the Second World War a movement in contemporary United States psychoanalysis gradually replaced the ideas of Freud and his emphasis on the "I" in the psychoanalytic process, with forms of relational therapy, assuming that the self was ab initio intersubjectively formed and could be altered fundamentally by focus on intersubjective processes. The author contends that this attitude makes it less likely for the psychoanalyst to focus on the regressive transferences from which derivatives of the private self arise and to grasp the phenomenological whole of the patient (p. 625).

    Full Text Available In der Veröffentlichung ihrer Habilitationsschrift geht Gaja von Sychowski das Vorhaben an, eine Allgemeine Pädagogik im Kontext poststrukturalistischen Denkens zu entwerfen. Damit greift sie nicht nur ein längst überfälliges Thema auf, es gelingt ihr zudem, dieses auf höchstem theoretischem Niveau zu bearbeiten. Die formalistische Konsequenz, mit der die Autorin ihre Forschung vorantreibt, ist dabei jedoch zwiespältig: Zwar schlägt sie durch die Reduzierung von Komplexität Brücken zwischen verschiedenen Disziplinen, andererseits verliert Geschlecht, wenn es schließlich unter Performanz subsumiert wird, an Bedeutung, und es entsteht so der Grundriss einer Allgemeinen Pädagogik, in welcher die subjektkonstituierende Macht von Geschlecht unterschlagen wird.In the publication of her professorial dissertation, Gaja von Sychowski intends to design a general pedagogy within the context of poststructuralist thinking. In doing so, she not only addresses a long overdue topic, but she also succeeds in elaborating it on a most abstract level. However, the formalistic consistency that the author uses to advance her research is ambivalent: on the one hand, the reduction of complexity bridges gaps between different disciplines, on the other hand, gender loses meaning if it is eventually subsumed under performance. Consequently, an outline of a general pedagogy, which omits the subject-constituting power of gender, emerges.

    Spiropyran-modified porous silicon (spiro-PS) was used for the first time as an organic–inorganic hybrid material by using reversible photoluminescence (PL). Before spiropyran modification, the peak wavelength from PS was approximately 600 nm. Subsequent spiropyran modification strongly quenched the PL intensity, from 15,000 to 2000 counts. However, under UV light irradiation, the PL intensity from spiro-PS was increased gradually to 20,000 counts because of the photoinduced ring opening from a colorless spiropyran (SP-form) to a colored merocyanine (MC-form). Furthermore, the resulting peak wavelength of the PL of an MC–PS sample red-shifted from 600 to 650 nm, and the PL intensity was higher than that of unmodified PS. Because the fluorescence emission band (500–700 nm) of PS substantially overlapped the absorption band (500–700 nm) of the MC-form of spiropyran, the energy transfer from the PS (donor) to the open-ring-state MC-form (acceptor) occurs efficiently. The intensity of the PL from spiro-PS can be reversibly modulated using a heat stimulus. The current demonstrations have potential in reversible solid-state lighting or data storage applications. - Highlights: • Spiropyran-modified porous silicon (spiro-PS) was used for the first time as an organic–inorganic hybrid material with reversible photoluminescence (PL). • UV light irradiation make PL intensity from spiro-PS increased due to the photo-induced ring opening process. • The energy transfer from the PS (donor) to the open-ring state of spiropyran (acceptor) was to be efficient due to the fluorescence emission band of PS substantially overlapped with the absorption band of the ring-opened spiro. • The intensity of the PL from spiro-PS can be reversibly modulated using a heat stimulus

    Lead halide perovskite solar cells with remarkable power conversion efficiency have attracted much attention in recent years. However, there still exist many problems with their use that are not completely understood, and further studies are needed. Herein, the hole-transport layer dependence of the photovoltaic performance of perovskite solar cells is investigated in detail. It is found that devices freshly prepared using pristine 2,2',7,7'-tetrakis-(N,N-di-p-methoxyphenylamine)-9,9'-spirobifluorene (spiro-OMeTAD) and Li-doped spiro-OMeTAD as hole-transport layers exhibit S-shaped current density-voltage curves with poor fill factors. The devices show progressively improved fill factors and efficiencies upon exposure to air, which is attributed to air-induced conductivity improvement in the spiro-OMeTAD layer. After introducing a cobalt salt dopant (FK209) into the spiro-OMeTAD layer, the corresponding devices show remarkable performance without the need of air exposure. These results confirm that the dopant not only increases the conductivity of spiro-OMeTAD layer, but also tunes the surface potential, which helps to improve charge transport and reduce the recombination loss. © 2017 Wiley-VCH Verlag GmbH & Co.

    Full Text Available Near steady-state photoinduced absorption (PIA and UV-Vis absorption spectroscopy are used to characterize the pore filling of spiro-MeOTAD (2,2′,7,7′-tetrakis-(N,N-di-p-methoxyphenylamine9,9′-spirobifluorene into the nanoparticulate TiO2 electrode of a solid-state dye-sensitized solar cell (ssDSC. The volumetric ratio of filled to unfilled pore volumes, as well as the optical signature of interacting chemical species, that is, the hole-transfer yield (HTY, are investigated. PIA spectroscopy is used to measure the HTY, relative to the amount of spiro-MeOTAD present, without needing to determine the extinction coefficients of the dye and spiro-MeOTAD cation species. The Beer-Lambert law is used to relate the relative PIA signal to the penetration length of the hole-conductor in the TiO2 film. For the sample thickness range of 1.4–5 μm investigated here, the optimum characteristic penetration length is determined to be 3.1+0.46 μm, which is compared to 1.4 μm for the 200 mg mL−1 concentration of spiro-MeOTAD conventionally used. Therefore, doubling the effective penetration of spiro-MeOTAD is necessary to functionalize all the dye molecules in a ssDSC.

    The first study of the reaction between nucleophilic carbenes and ketenimines is reported. The interaction of thiazole and benzothiazole carbenes with ketenimines proceeded in a chemospecific and stereoselective manner to produce thiazole- and benzothiazole-spiro-pyrrole derivatives generally in good yields. The reaction was proposed to proceed via a tandem nucleophilic addition of carbene to the C=N bond of ketenimine followed by a stepwise [3+2] cycloaddition of the 1,3-dipolar intermediate with the C=C bond of ketenimine. This reaction provides a powerful protocol for the construction of novel polyfunctional thiazole-spiro-pyrrole or benzothiazole-spiro-pyrrole compounds that are not readily accessible by other methods.

  2. Atmospheric effects on the photovoltaic performance of hybrid perovskite solar cells

    Organometal trihalide perovskite solar cells have recently attracted lots of attention in the photovoltaic community due to their escalating efficiency and solution processability. The most efficient organometallic mixed-halide sensitized solar cells often employ 2,2′7,7′-tetrakis-(N,N-di-p-methoxyphenyl-amine)-9,9′-spirobifluorene (spiro-MeOTAD) as the hole-transporting material. In this work, we investigated the effect of different atmospheric storage conditions, particularly vacuum, dry nitrogen, and dry air, on the photovoltaic performance of TiO2-CH3NH3PbI3-xClx-spiro-MeOTAD solar cells. We found that spin coating of spiro-MeOTAD in an oxygen atmosphere alone was not adequate to functionalize its hole-transport property completely, and our systematic experiments revealed that the device efficiency depends on the ambient atmospheric conditions during the drying process of spiro-MeOTAD. Complementary incident photon to current conversion efficiency (IPCE), light absorption and photoluminescence quenching measurements allowed us to attribute the atmosphere-dependent efficiency to the improved electronic characteristics of the solar cells. Furthermore, our Fourier transform infrared and electrical impedance measurements unambiguously detected modifications in the spiro-MeOTAD after the drying processes in different gas environments. Our findings demonstrate that proper oxidization and p-doping in functionalizing spiro-MeOTAD play a very critical role in determining device performance. These findings will facilitate the search for alternative hole-transporting materials in high-performance perovskite solar cells with long-term stability.

The new compounds were investigated for antimicrobial activity. Compounds 2c, 8b,c, 9b and 10b were the most potent ones against both Gram-negative and Gram-positive bacteria. Compound 8c exhibited higher antifungal activity towards the examined fungi with MIC of 1-2 μmol mL-1 compared to ketoconazole (MIC 2-3 μmol mL-1 .

    The phosphine-catalyzed [3 + 2]-cycloaddition of 5-methylenehydantoins 4 with the ylides 5, derived from addition of tributylphosphine to the 2-butynoic acid derivatives, 6a-d, gives spiro-heterocyclic products. The camphor sultam derivative 6b gives optically active products. Noteable was that the ylides derived from ethyl 2-butynoate and the 3-(2-butynoyl)-1,3-oxazolidin-2-one derivatives 6c and 6d gave spiro-heterocyclic products with reverse regioselectivities. The N,N-dibenzylprotected cycloadduct has been converted to carbocyclic hydantocidin and 6,7-diepi-carbocyclic hydantocidin.

    This report concerns two proposals of law which have a common concern: warranting the rights of the miners and retired miners after the disappearing of the national association of retired miners management (ANGR), the members of which are the three companies of Charbonnages de France group (French national coal board), today undergoing a progressive shut-down. In this report, it is proposed to merge the contributions of both proposals with the creation of a new national agency for the warranty of the perenniality of miners' rights. It proposes also some necessary adaptations of the structures of Charbonnages de France group and some dispositions aiming at modernizing the French mining law and ensuring the exploitation of solid mineral fuels after the disappearing of the group.
