Full Text Available The aim of phytogeographical analysis is to determine the plant species origin, genesis and migrations. The study results contribute to the knowledge of phytogeographical classification of the particular regions. Different chorions, by their effects, determine the flora structure and composition. The aim of the floristic research of Divčibare was to identify the diversity of flora in this region, i.e., in a wider sense, the diversity of flora in Serbia. Phytogeographical analysis was based on floristic research. The identified plant species were classified into the corresponding floral elements, area groups and area types. The data on diversity and the degree of representation in the flora of Divčibare were obtained based on the percentage of each area type. It was concluded that the flora of Divčibare has a transitional, Central European-Mediterranean-Pontic character.

Wright-Fisher diffusion bridges.

Griffiths, Robert C; Jenkins, Paul A; Spanò, Dario

The trajectory of the frequency of an allele which begins at x at time 0 and is known to have frequency z at time T can be modelled by the bridge process of the Wright-Fisher diffusion. Bridges when x=z=0 are particularly interesting because they model the trajectory of the frequency of an allele which appears at a time, then is lost by random drift or mutation after a time T. The coalescent genealogy back in time of a population in a neutral Wright-Fisher diffusion process is well understood. In this paper we obtain a new interpretation of the coalescent genealogy of the population in a bridge from a time t∈(0,T). In a bridge with allele frequencies of 0 at times 0 and T the coalescence structure is that the population coalesces in two directions from t to 0 and t to T such that there is just one lineage of the allele under consideration at times 0 and T. The genealogy in Wright-Fisher diffusion bridges with selection is more complex than in the neutral model, but still with the property of the population branching and coalescing in two directions from time t∈(0,T). The density of the frequency of an allele at time t is expressed in a way that shows coalescence in the two directions. A new algorithm for exact simulation of a neutral Wright-Fisher bridge is derived. This follows from knowing the density of the frequency in a bridge and exact simulation from the Wright-Fisher diffusion. The genealogy of the neutral Wright-Fisher bridge is also modelled by branching Pólya urns, extending a representation in a Wright-Fisher diffusion. This is a new very interesting representation that relates Wright-Fisher bridges to classical urn models in a Bayesian setting. Copyright © 2017 Elsevier Inc. All rights reserved.

SUSTAINABLE ORIGINS IN ARCHITECTURE OF FRANK LLOYD WRIGHT

Directory of Open Access Journals (Sweden)

Martina Zbašnik-Senegačnik

2012-10-01

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

Regulation of Na+ channel inactivation by the DIII and DIV voltage-sensing domains.

Hsu, Eric J; Zhu, Wandi; Schubert, Angela R; Voelker, Taylor; Varga, Zoltan; Silva, Jonathan R

2017-03-06

Functional eukaryotic voltage-gated Na + (Na V ) channels comprise four domains (DI-DIV), each containing six membrane-spanning segments (S1-S6). Voltage sensing is accomplished by the first four membrane-spanning segments (S1-S4), which together form a voltage-sensing domain (VSD). A critical Na V channel gating process, inactivation, has previously been linked to activation of the VSDs in DIII and DIV. Here, we probe this interaction by using voltage-clamp fluorometry to observe VSD kinetics in the presence of mutations at locations that have been shown to impair Na V channel inactivation. These locations include the DIII-DIV linker, the DIII S4-S5 linker, and the DIV S4-S5 linker. Our results show that, within the 10-ms timeframe of fast inactivation, the DIV-VSD is the primary regulator of inactivation. However, after longer 100-ms pulses, the DIII-DIV linker slows DIII-VSD deactivation, and the rate of DIII deactivation correlates strongly with the rate of recovery from inactivation. Our results imply that, over the course of an action potential, DIV-VSDs regulate the onset of fast inactivation while DIII-VSDs determine its recovery. © 2017 Hsu et al.

SecA is required for membrane targeting of the cell division protein DivIVA in vivo

Directory of Open Access Journals (Sweden)

Sven eHalbedel

2014-02-01

Full Text Available The conserved protein DivIVA is involved in different morphogenetic processes in Gram-positive bacteria. In Bacillus subtilis, the protein localises to the cell division site and cell poles, and functions as a scaffold for proteins that regulate division site selection, and for proteins that are required for sporulation. To identify other proteins that bind to DivIVA, we performed an in vivo cross-linking experiment. A possible candidate that emerged was the secretion motor ATPase SecA. SecA mutants have been described that inhibit sporulation, and since DivIVA is necessary for sporulation, we examined the localisation of DivIVA in these mutants. Surprisingly, DivIVA was delocalised, suggesting that SecA is required for DivIVA targeting. To further corroborate this, we performed SecA depletion and inhibition experiments, which provided further indications that DivIVA localisation depends on SecA. Cell fractionation experiments showed that SecA is important for binding of DivIVA to the cell membrane. This was unexpected since DivIVA does not contain a signal sequence, and is able to bind to artificial lipid membranes in vitro without support of other proteins. SecA is required for protein secretion and membrane insertion, and therefore its role in DivIVA localisation is likely indirect. Possible alternative roles of SecA in DivIVA folding and/or targeting are discussed.

An automated full-symmetry Patterson search method

International Nuclear Information System (INIS)

Rius, J.; Miravitlles, C.

1987-01-01

A full-symmetry Patterson search method is presented that performs a molecular coarse rotation search in vector space and orientation refinement using the σ function. The oriented molecule is positioned using the fast translation function τ 0 , which is based on the automated interpretation of τ projections using the sum function. This strategy reduces the number of Patterson-function values to be stored in the rotation search, and the use of the τ 0 function minimizes the required time for the development of all probable rotation search solutions. The application of this method to five representative test examples is shown. (orig.)

We present a family of scalable preconditioners for matrices arising in the discretization of $H(div)$ problems using the lowest order Raviart--Thomas finite elements. Our approach belongs to the class of “auxiliary space''--based methods and requires only the finite element stiffness matrix plus some minimal additional discretization information about the topology and orientation of mesh entities. Also, we provide a detailed algebraic description of the theory, parallel implementation, and different variants of this parallel auxiliary space divergence solver (ADS) and discuss its relations to the Hiptmair--Xu (HX) auxiliary space decomposition of $H(div)$ [SIAM J. Numer. Anal., 45 (2007), pp. 2483--2509] and to the auxiliary space Maxwell solver AMS [J. Comput. Math., 27 (2009), pp. 604--623]. Finally, an extensive set of numerical experiments demonstrates the robustness and scalability of our implementation on large-scale $H(div)$ problems with large jumps in the material coefficients.

Parallel Solver for H(div) Problems Using Hybridization and AMG

Energy Technology Data Exchange (ETDEWEB)

In this paper, a scalable parallel solver is proposed for H(div) problems discretized by arbitrary order finite elements on general unstructured meshes. The solver is based on hybridization and algebraic multigrid (AMG). Unlike some previously studied H(div) solvers, the hybridization solver does not require discrete curl and gradient operators as additional input from the user. Instead, only some element information is needed in the construction of the solver. The hybridization results in a H1-equivalent symmetric positive definite system, which is then rescaled and solved by AMG solvers designed for H1 problems. Weak and strong scaling of the method are examined through several numerical tests. Our numerical results show that the proposed solver provides a promising alternative to ADS, a state-of-the-art solver [12], for H(div) problems. In fact, it outperforms ADS for higher order elements.

The wind tunnel test results have been published in the literature as summarized at the end of this report. As part of the education program, an introduction to engineering course module was designed and tested on 80 freshman engineering students at Old Dominion University. The five-week module required that five-person teams design, build and fly a radio-controlled airplane using only the wind tunnel data developed by the Wright brothers in 1902. That module is described in Sparks and Ash (2001). The Principal Investigator has co-authored one dozen publications resulting from this research, as listed at the end of this report. The Principal Investigator has given fourteen lectures on the Wright brother testing program and has appeared in two documentary television programs (summarized at the end of this report). Speaking invitations have continued since the completion of the project.

Asymmetric division and differential gene expression during a bacterial developmental program requires DivIVA.

Directory of Open Access Journals (Sweden)

Prahathees Eswaramoorthy

2014-08-01

Full Text Available Sporulation in the bacterium Bacillus subtilis is a developmental program in which a progenitor cell differentiates into two different cell types, the smaller of which eventually becomes a dormant cell called a spore. The process begins with an asymmetric cell division event, followed by the activation of a transcription factor, σF, specifically in the smaller cell. Here, we show that the structural protein DivIVA localizes to the polar septum during sporulation and is required for asymmetric division and the compartment-specific activation of σF. Both events are known to require a protein called SpoIIE, which also localizes to the polar septum. We show that DivIVA copurifies with SpoIIE and that DivIVA may anchor SpoIIE briefly to the assembling polar septum before SpoIIE is subsequently released into the forespore membrane and recaptured at the polar septum. Finally, using super-resolution microscopy, we demonstrate that DivIVA and SpoIIE ultimately display a biased localization on the side of the polar septum that faces the smaller compartment in which σF is activated.

The aim of this article is a general description of the so-called Patterson-function direct methods (PFDM), from their origin to their present state. It covers a 20-year period of methodological contributions to crystal structure solution, most of them published in Acta Crystallographica Section A. The common feature of these variants of direct methods is the introduction of the experimental intensities in the form of the Fourier coefficients of origin-free Patterson-type functions, which allows the active use of both strong and weak reflections. The different optimization algorithms are discussed and their performances compared. This review focuses not only on those PFDM applications related to powder diffraction data but also on some recent results obtained with electron diffraction tomography data.

Wright was born in 1861 in Middleton Tyas, Yorkshire, where his father, an Irish protestant and considerable Hebrew scholar, was the minister. Almroth's Swedish mother, the daughter of NW Almroth, governor of the mint in Stockholm, was responsible for his unusual first name. She had the rare distinction of having served as a nurse with Florence Nightingale in the hospital at Scutari in the Crimean War.

Lee, Robert E; Young, Robert H; Castleman, Benjamin

2002-01-01

James Homer Wright (1869-1928), the eldest son of a Pittsburgh glass merchant, was educated in Baltimore and practiced pathology in Boston from 1893 until his death in 1928. In 1896, when not quite 27 years old, he assumed directorship of the newly founded Pathology Laboratory at the Massachusetts General Hospital, a post he held for the next 30 years. He is remembered eponymously by the blood cell stain that bears his name and the Homer Wright pseudorosettes of neuroblastoma, but he made many additional contributions to pathology. These include the following: determination of the cellular lineage of multiple myeloma, identification of the megakaryocyte as the cell of origin of blood platelets, recognition of the cell of origin of the neuroblastoma, demonstration of spirochetes in syphilitic aneurysms of the aorta, and clarification of misconceptions about actinomycosis. Additionally, Wright coauthored, with Dr. Frank B. Mallory, the book Pathological Technique, which was a staple of laboratories for >40 years and exemplifies Wright's wide-ranging interests in, and contributions to, practical aspects of pathology including staining, culture and frozen section techniques, photography, and development of the rotary microtome. He received Honorary Doctor of Science Degrees from Harvard University, the University of Maryland (his alma mater), and the University of Missouri. He was the recipient of the Gross prize in 1905 for his publication on actinomycosis and the Boylston Medical Prize in 1908 for his discovery of the origin of platelets, and he was inducted into the American Academy of Arts and Sciences in 1915. Although shy and somewhat austere in the workplace, a different side was shown by his anonymously sending flowers to a young Norwegian opera singer whom he subsequently married. The pathology laboratories of the Massachusetts General Hospital were named the "James Homer Wright Pathology Laboratories" in 1956. Today James Homer Wright is remembered and

Design information verification (DIV) of closed geological repositories (SAGOR activity 3c)

International Nuclear Information System (INIS)

Myatt, J.

1998-02-01

Following IAEA Advisory and Consultants Group meetings in September 1988 and in May 1991 respectively an IAEA multi-national Support Programme Task was initiated to consider the 'Development of Safeguards for Final Disposal of Spent Fuel in Geological Repositories' (SAGOR). A 'Technical Coordination Committee' (TCC) was set up with invited representatives from those Member State Support Programmes wishing to be involved. The joint programme, through the TCC, was given the task of studying the safeguards requirements in: conditioning plant (where the spent fuel is prepared for transfer to the repository); operating repositories (i.e. those in which the fuel is being emplaced); closed repositories. At the first meeting of the TCC in Washington in July 1994 the UK undertook to provide a study of the Design Information Verification (DIV) required in all three areas. For this activity the requirements, techniques and procedures for the Design Information Verification (DIV) of closed repositories have been considered. In completing the study the findings reported for activities 1b/c and 2c (descriptions of a Model Repository and Potential Diversion Paths, respectively) have been used in formulating any conclusions reached. It is also debatable as to whether this activity is strictly speaking DIV or is one of surveillance. As undeclared access can only be made to the emplacement areas of the repository by altering the physical makeup of the surrounding area; i.e. physically changing the 'design' of the surrounding area, however, this is deemed to be DIV. Although the techniques used appear to be those of surveillance they are being applied in this case as the tools of DIV. As with any facility there are a number of stages in its lifetime. For the purposes of this report the operating life of a repository is defined as being the time from inception to when it is finally decommissioned and sealed with the ground surface returned to being a green field. The repository is

The age of the earth: the approach of Clair Cameron Patterson

International Nuclear Information System (INIS)

Trouillet, F.

2010-01-01

This article is a practical physics course designed for high school students that illustrates the Patterson's approach to determine the age of the earth. In 1953, the result published by Patterson (4.55 ± 0.07)*10 9 y was the first correct estimation of the age of the earth. His approach is based on the idea that the isotopic composition of meteorites can give information on the origin of the solar system. He assumed that meteorites and earth were formed at the same time and from a common homogeneous material (in terms of lead and uranium isotopic compositions). Patterson determined the isotopic lead composition of meteorite samples and inferred the age of the earth. The first part of the article gives the kinetics equations of Pb 206 and Pb 207 , these 2 lead isotopes were present originally and have been created since through the decay of U 238 and U 235 respectively. The second part present the application to experimental data from 5 meteorite samples. A conclusion is drawn that highlights the limits of the method: the measurement of the lead composition of the samples is very delicate to do because the meteorites contain very low amounts of lead (about 1 ppm) and the crossing of the atmosphere could have contaminated them with lead from humane activities.

Structural disorder in the decagonal Al-Co-Ni. I. Patterson analysis of diffuse x-ray scattering data

International Nuclear Information System (INIS)

Kobas, Miroslav; Weber, Thomas; Steurer, Walter

2005-01-01

The three-dimensional (3D) difference Patterson (autocorrelation) function of a disordered quasicrystal (Edagawa phase) has been analyzed. 3D diffuse x-ray diffraction data were collected in situ at 300, 1070, and 1120 K. A method, the punch-and-fill technique, has been developed for separating diffuse scattering and Bragg reflections. Its potential and limits are discussed in detail. The different Patterson maps are interpreted in terms of intercluster correlations as a function of temperature. Both at high and low temperatures, the clusters decorate the vertices of the same quasiperiodic covering. At low temperatures, for the disordered part of the structure, short-range intercluster correlations are present, whereas at higher temperatures, medium-range intercluster correlations are formed. This indicates disorder mainly inside clusters at low temperatures, whereas at higher temperatures disorder takes place inside larger superclusters. Qualitatively, the Patterson maps may be interpreted by intercluster correlations mainly inside pentagonal superclusters below 1120 K, and inside the larger decagonal superclusters at 1120 K. The results of our diffraction study are published in two parts. Part I focuses on the 3D Patterson analysis based on experimental data, Part II reports modeling of structural disorder in decagonal Al-Co-Ni

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

Directory of Open Access Journals (Sweden)

Ana Tagliari

2011-12-01

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

Accurate macromolecular crystallographic refinement: incorporation of the linear scaling, semiempirical quantum-mechanics program DivCon into the PHENIX refinement package

Borbulevych, Oleg Y.; Plumley, Joshua A.; Martin, Roger I. [QuantumBio Inc., 2790 West College Avenue, State College, PA 16801 (United States); Merz, Kenneth M.

Semiempirical quantum-chemical X-ray macromolecular refinement using the program DivCon integrated with PHENIX is described. Macromolecular crystallographic refinement relies on sometimes dubious stereochemical restraints and rudimentary energy functionals to ensure the correct geometry of the model of the macromolecule and any covalently bound ligand(s). The ligand stereochemical restraint file (CIF) requires a priori understanding of the ligand geometry within the active site, and creation of the CIF is often an error-prone process owing to the great variety of potential ligand chemistry and structure. Stereochemical restraints have been replaced with more robust functionals through the integration of the linear-scaling, semiempirical quantum-mechanics (SE-QM) program DivCon with the PHENIX X-ray refinement engine. The PHENIX/DivCon package has been thoroughly validated on a population of 50 protein–ligand Protein Data Bank (PDB) structures with a range of resolutions and chemistry. The PDB structures used for the validation were originally refined utilizing various refinement packages and were published within the past five years. PHENIX/DivCon does not utilize CIF(s), link restraints and other parameters for refinement and hence it does not make as many a priori assumptions about the model. Across the entire population, the method results in reasonable ligand geometries and low ligand strains, even when the original refinement exhibited difficulties, indicating that PHENIX/DivCon is applicable to both single-structure and high-throughput crystallography.

Exact simulation of conditioned Wright-Fisher models.

Science.gov (United States)

Zhao, Lei; Lascoux, Martin; Waxman, David

2014-12-21

Forward and backward simulations play an increasing role in population genetics, in particular when inferring the relative importance of evolutionary forces. It is therefore important to develop fast and accurate simulation methods for general population genetics models. Here we present an exact simulation method that generates trajectories of an allele׳s frequency in a finite population, as described by a general Wright-Fisher model. The method generates conditioned trajectories that start from a known frequency at a known time, and which achieve a specific final frequency at a known final time. The simulation method applies irrespective of the smallness of the probability of the transition between the initial and final states, because it is not based on rejection of trajectories. We illustrate the method on several different populations where a Wright-Fisher model (or related) applies, namely (i) a locus with 2 alleles, that is subject to selection and mutation; (ii) a locus with 3 alleles, that is subject to selection; (iii) a locus in a metapopulation consisting of two subpopulations of finite size, that are subject to selection and migration. The simulation method allows the generation of conditioned trajectories that can be used for the purposes of visualisation, the estimation of summary statistics, and the development/testing of new inferential methods. The simulated trajectories provide a very simple approach to estimating quantities that cannot easily be expressed in terms of the transition matrix, and can be applied to finite Markov chains other than the Wright-Fisher model.

Single and simultaneous binary mergers in Wright-Fisher genealogies.

Science.gov (United States)

Melfi, Andrew; Viswanath, Divakar

2018-05-01

The Kingman coalescent is a commonly used model in genetics, which is often justified with reference to the Wright-Fisher (WF) model. Current proofs of convergence of WF and other models to the Kingman coalescent assume a constant sample size. However, sample sizes have become quite large in human genetics. Therefore, we develop a convergence theory that allows the sample size to increase with population size. If the haploid population size is N and the sample size is N 1∕3-ϵ , ϵ>0, we prove that Wright-Fisher genealogies involve at most a single binary merger in each generation with probability converging to 1 in the limit of large N. Single binary merger or no merger in each generation of the genealogy implies that the Kingman partition distribution is obtained exactly. If the sample size is N 1∕2-ϵ , Wright-Fisher genealogies may involve simultaneous binary mergers in a single generation but do not involve triple mergers in the large N limit. The asymptotic theory is verified using numerical calculations. Variable population sizes are handled algorithmically. It is found that even distant bottlenecks can increase the probability of triple mergers as well as simultaneous binary mergers in WF genealogies. Copyright © 2018 Elsevier Inc. All rights reserved.

In this paper, we introduce a weak Galerkin least-squares method for solving div-curl problem. This finite element method leads to a symmetric positive definite system and has the flexibility to work with general meshes such as hybrid mesh, polytopal mesh and mesh with hanging nodes. Error estimates of the finite element solution are derived. The numerical examples demonstrate the robustness and flexibility of the proposed method.

Apoprotein Structure and Metal Binding Characterization of a de Novo Designed Peptide, α3DIV, that Sequesters Toxic Heavy Metals.

Plegaria, Jefferson S; Dzul, Stephen P; Zuiderweg, Erik R P; Stemmler, Timothy L; Pecoraro, Vincent L

2015-05-12

De novo protein design is a biologically relevant approach that provides a novel process in elucidating protein folding and modeling the metal centers of metalloproteins in a completely unrelated or simplified fold. An integral step in de novo protein design is the establishment of a well-folded scaffold with one conformation, which is a fundamental characteristic of many native proteins. Here, we report the NMR solution structure of apo α3DIV at pH 7.0, a de novo designed three-helix bundle peptide containing a triscysteine motif (Cys18, Cys28, and Cys67) that binds toxic heavy metals. The structure comprises 1067 NOE restraints derived from multinuclear multidimensional NOESY, as well as 138 dihedral angles (ψ, φ, and χ1). The backbone and heavy atoms of the 20 lowest energy structures have a root mean square deviation from the mean structure of 0.79 (0.16) Å and 1.31 (0.15) Å, respectively. When compared to the parent structure α3D, the substitution of Leu residues to Cys enhanced the α-helical content of α3DIV while maintaining the same overall topology and fold. In addition, solution studies on the metalated species illustrated metal-induced stability. An increase in the melting temperatures was observed for Hg(II), Pb(II), or Cd(II) bound α3DIV by 18-24 °C compared to its apo counterpart. Further, the extended X-ray absorption fine structure analysis on Hg(II)-α3DIV produced an average Hg(II)-S bond length at 2.36 Å, indicating a trigonal T-shaped coordination environment. Overall, the structure of apo α3DIV reveals an asymmetric distorted triscysteine metal binding site, which offers a model for native metalloregulatory proteins with thiol-rich ligands that function in regulating toxic heavy metals, such as ArsR, CadC, MerR, and PbrR.

In 1965, Intel co-founder Gordon Moore made an astonishing prediction - that every two years processing power would double. This prediction has always proved accurate. Accordingly, the first Intel processor produced in 1975 was equipped with 2,300 transistors whereas the latest edition has 55 million. Today we have this extraordinary process of miniaturisation to thank for cell phones, computers and other, ever more compact electronic marvels. But where will the miniaturisation race end? What will happen when electronic etchings reach the size of an atom? These questions are on the programme of the 10th Wright Science Colloquia from 18 to 22 November. Five world-renowned specialists will explain to the general public the saga of miniaturisation. The Wright Colloquia take place every two years in Geneva and aim to inform the general public about the latest advances in science.   Monday 18 November: 'Shaping the World at the Atomic Scale', by Donald Eigler, IBM, Almaden, USA.   Tuesday 19...

Passion play: Will Wright and games for science learning

Science.gov (United States)

Ching, Dixie

2012-12-01

Researchers and instructional designers are exploring the possibilities of using video games to support STEM education in the U.S., not only because they are a popular media form among youth, but also because well-designed games often leverage the best features of inquiry learning. Those interested in using games in an educational capacity may benefit from an examination of the work of video game designer Will Wright. Wright designs through a constructivist lens and his open-ended, sandbox games ( SimCity, The Sims, Spore) present wide "possibility spaces" that allow players to exercise their critical thinking and problem solving skills. His games invoke a delight in discovery that inspire creative acts and interest-driven learning both during and outside of the game. Finally, he reminds us that failure-based learning is a viable strategy for building expertise and understanding.

Analysis of biological spectrum of Divčibare flora

Directory of Open Access Journals (Sweden)

Popović Ivana

2006-01-01

Full Text Available One of the essential analyses which is performed during the floristic study of a region is the analysis of the biological spectrum. The analysis of the biological spectrum of the flora includes the determination of the type of life form for each taxon described in the flora of the study region. If it is considered that life form is a specific structural-functional response to the environmental effects and the result of the adaptation during the species evolution, it is clear that the basic characteristics of the site are more or less reflected in any life form. This fact is confirmed by the analysis of the biological spectrum of Divčibare flora. The study results are in correlation with the results of the analysis of the biological spectrum of the flora of Serbia and the Balkan Peninsula.

Septal membrane localization by C-terminal amphipathic α-helices of MinD in Bacillus subtilis mutant cells lacking MinJ or DivIVA.

Science.gov (United States)

Ishikawa, Kazuki; Matsuoka, Satoshi; Hara, Hiroshi; Matsumoto, Kouji

2017-10-18

The Min system, which inhibits assembly of the cytokinetic protein FtsZ, is largely responsible for positioning the division site in rod-shaped bacteria. It has been reported that MinJ, which bridges DivIVA and MinD, is targeted to the cell poles by an interaction with DivIVA, and that MinJ in turn recruits MinCD to the cell poles. MinC, however, is located primarily at active division sites at mid-cell when expressed from its native promoter. Surprisingly, we found that Bacillus subtilis MinD is located at nascent septal membranes and at an asymmetric site on lateral membranes between nascent septal membranes in filamentous cells lacking MinJ or DivIVA. Bacillus subtilis MinD has two amphipathic α-helices rich in basic amino acid residues at its C-terminus; one of these, named MTS1 here, is the counterpart of the membrane targeting sequence (MTS) in Escherichia coli MinD while the other, named MTS-like sequence (MTSL), is the nearest helix to MTS1. These amphipathic helices were located independently at nascent septal membranes in cells lacking MinJ or DivIVA, whereas elimination of the helices from the wild type protein reduced its localization considerably. MinD variants with altered MTS1 and MTSL, in which basic amino acid residues were replaced with proline or acidic residues, were not located at nascent septal membranes, indicating that the binding to the nascent septal membranes requires basic residues and a helical structure. The septal localization of MTSL, but not of MTS1, was dependent on host cell MinD. These results suggest that MinD is targeted to nascent septal membranes via its C-terminal amphipathic α-helices in B. subtilis cells lacking MinJ or DivIVA. Moreover, the diffuse distribution of MinD lacking both MTSs suggests that only a small fraction of MinD depends on MinJ for its localization to nascent septal membranes.

Lessons from cognitive neuropsychology for cognitive science: a reply to Patterson and Plaut (2009).

Science.gov (United States)

Coltheart, Max

2010-01-01

A recent article in this journal (Patterson & Plaut, 2009) argued that cognitive neuropsychology has told us very little over the past 30 or 40 years about "how the brain accomplishes its cognitive business." This may well be true, but it is not important, because the principal aim of cognitive neuropsychology is not to learn about the brain. Its principal aim is instead to learn about the mind, that is, to elucidate the functional architecture of cognition. I show that this is so (a) via extensive quotations from leading figures in this field and (b) by analysis of the subject matter of articles in the leading journal in the field, Cognitive Neuropsychology. Recent reviews of the past 25 years of work in this field (Coltheart & Caramazza, 2006) have concluded that cognitive neuropsychology has told us much about the functional architecture of cognition in a variety of cognitive domains. Patterson and Plaut (2009) did not consider this aim of cognitive neuropsychology. Therefore, their conclusions that cognitive neuropsychology has not been successful, and that this is because the particular methods it uses are flawed, are not justified.

Wright tariffs in the Spanish electricity industry: the case of residential consumption

International Nuclear Information System (INIS)

Castro-Rodriguez, F.

1999-01-01

In this paper a capacity price model is developed for the Spanish electricity industry which allows the presentation of the Spanish utilization level tariffs as an example of duration tariffs (Wright tariffs) when duration is approximated by the ratio of consumption to power used. Using this model and data on the residential consumption of electricity, several optimal two-part tariffs are computed, considering different hypothesis on the configuration of the generating equipment. It has been found that the optimal tariff maintaining universal service increases welfare if the generating equipment and the output assignment to the different technologies are taken as given. Furthermore, if the regulator is concerned not only with efficiency, but also with distributive issues, then welfare losses associated with the existing regulatory regime are even larger

Changes of hyoid bone position following treatment of class II div1 malocclusion with Farmand functional appliance

Directory of Open Access Journals (Sweden)

Yassaei S

2007-01-01

Full Text Available Background and Aim: Unlike other bones of the head and neck, hyoid bone has no bony articulations. It is connected to mandible, cranium and pharynx through muscles and ligaments. During treatment with functional appliance in patients with class II div1 malocclusion, mandible is positioned in inferior and anterior direction. Regarding the relation between hyoid and mandibular bone, alterations of hyoid bone position can be a result of functional appliance therapy. The aim of this study was to evaluate the changes of hyoid bone position following treatment with Farmand functional appliance in patients with class II div 1 malocclusion. Materials and Methods: In this before-after clinical trial, 28 patients with class II div 1 malocclusion which were under treatment with Farmand functional appliance for 11 months were selected. Facial growth in vertical, normal or horizontal direction was determined by cephalometric measurement. Data were analyzed with Paired-t test to compare the differences of mean values pre and post treatment. Variance analysis was used to compare the three growth patterns. P<0.05 was considered as the limit of significance. Results: Hyoid bone shifted significantly forward in horizontal dimension (P<0.01 and non-significantly upward in vertical dimension. There was no significant difference among the three studied groups with respect to hyoid bone position alterations in horizontal dimension but significant difference was observed between horizontal and vertical growth pattern in vertical dimension (P<0.05. There was significant correlation between decrease of ANB angle and forward movement of hyoid bone. Conclusion: Based on the results of this study, treatment with Farmand functional appliance (Fa II leads to significant alterations in the position and anterior displacement of the hyoid bone.

Efficient augmented Lagrangian-type preconditioning for the Oseen problem using Grad-Div stabilization

KAUST Repository

Heister, Timo

2012-01-29

Efficient preconditioning for Oseen-type problems is an active research topic. We present a novel approach leveraging stabilization for inf-sup stable discretizations. The Grad-Div stabilization shares the algebraic properties with an augmented Lagrangian-type term. Both simplify the approximation of the Schur complement, especially in the convection-dominated case. We exploit this for the construction of the preconditioner. Solving the discretized Oseen problem with an iterative Krylov-type method shows that the outer iteration numbers are retained independent of mesh size, viscosity, and finite element order. Thus, the preconditioner is very competitive. © 2012 John Wiley & Sons, Ltd.

The wounded male persona and the mysterious feminine in the poetry of James Wright: a study in the transformation of the self.

Science.gov (United States)

Graves, M; Schermer, V L

1998-12-01

James Wright's work is multilayered. Taken as a whole, which Annie Wright's beautiful compilation, Above the River, allows one to do, Wright's poems (as well as his masterful "prose poems") have a pattern akin to a mythic cycle. "Mythemes" (Lévi-Strauss, 1979) recur as dialectic opposites from one poem to another, whether the abandoned male and mysterious woman, humankind and nature, blindness and seeing, secrets and revelation. Suggestive and symbolic forms such as birds, horses, earth, sky, the destitute, rivers, and adolescence weave themselves throughout in inner and outer "landscapes" of images and experiential moments. There is a frequent shift of "gestalts" between the inner world and external reality. Such a "blooming, buzzing confusion" of internal and external referents might appear to be psychotic and imply a loss of "reality testing." Chassaguet-Smirgel (1988), citing Oscar Wilde's The Picture of Dorian Gray as an example, contended that the artist narrowly averts psychosis by transforming it into a work of art. Surrealists, for whom the psychoanalyst Jacques Lacan was an important figure (cf. Sarup, 1992, pp. 17-27), elevated psychosis to the status of art, and Wright has been considered to be a surrealistic poet, although he himself denied such an affiliation. Hall (Wright, 1990, Introduction, pp. xxiii-xxxvii) suggests that Wright, in addition to an extensive history of alcoholism, from which he seemed to recover towards the end of his life, suffered from a major mental illness, which included episodes of severe depression, hospitalizations, and at least one suicide attempt. The severity of the asceticism and the extreme damage to the self in some Wright's work suggests their roots in early traumatic experiences. (A terribly damaged yet heroic personage, whose disfigurement perhaps symbolizes the poet's trauma, is "Hook" [ATR, pp. 315-316], about a man who gives his last few cents to the poet with a hook replacing his amputated hand.) Not enough is

Effects of the Ordering of Natural Selection and Population Regulation Mechanisms on Wright-Fisher Models.

Science.gov (United States)

He, Zhangyi; Beaumont, Mark; Yu, Feng

2017-07-05

We explore the effect of different mechanisms of natural selection on the evolution of populations for one- and two-locus systems. We compare the effect of viability and fecundity selection in the context of the Wright-Fisher model with selection under the assumption of multiplicative fitness. We show that these two modes of natural selection correspond to different orderings of the processes of population regulation and natural selection in the Wright-Fisher model. We find that under the Wright-Fisher model these two different orderings can affect the distribution of trajectories of haplotype frequencies evolving with genetic recombination. However, the difference in the distribution of trajectories is only appreciable when the population is in significant linkage disequilibrium. We find that as linkage disequilibrium decays the trajectories for the two different models rapidly become indistinguishable. We discuss the significance of these findings in terms of biological examples of viability and fecundity selection, and speculate that the effect may be significant when factors such as gene migration maintain a degree of linkage disequilibrium.

Theories that narrate the world: Ronald A. Fisher's mass selection and Sewall Wright's shifting balance.

Rosales, Alirio

2017-04-01

Theories are composed of multiple interacting components. I argue that some theories have narratives as essential components, and that narratives function as integrative devices of the mathematical components of theories. Narratives represent complex processes unfolding in time as a sequence of stages, and hold the mathematical elements together as pieces in the investigation of a given process. I present two case studies from population genetics: R. A. Fisher's "mas selection" theory, and Sewall Wright's shifting balance theory. I apply my analysis to an early episode of the "R. A. Fisher - Sewall Wright controversy." Copyright © 2017 Elsevier Ltd. All rights reserved.

Statistical Basis for Predicting Technological Progress

Forecasting technological progress is of great interest to engineers, policy makers, and private investors. Several models have been proposed for predicting technological improvement, but how well do these models perform? An early hypothesis made by Theodore Wright in 1936 is that cost decreases as a power law of cumulative production. An alternative hypothesis is Moore's law, which can be generalized to say that technologies improve exponentially with time. Other alternatives were proposed by Goddard, Sinclair et al., and Nordhaus. These hypotheses have not previously been rigorously tested. Using a new database on the cost and production of 62 different technologies, which is the most expansive of its kind, we test the ability of six different postulated laws to predict future costs. Our approach involves hindcasting and developing a statistical model to rank the performance of the postulated laws. Wright's law produces the best forecasts, but Moore's law is not far behind. We discover a previously unobserved regularity that production tends to increase exponentially. A combination of an exponential decrease in cost and an exponential increase in production would make Moore's law and Wright's law indistinguishable, as originally pointed out by Sahal. We show for the first time that these regularities are observed in data to such a degree that the performance of these two laws is nearly the same. Our results show that technological progress is forecastable, with the square root of the logarithmic error growing linearly with the forecasting horizon at a typical rate of 2.5% per year. These results have implications for theories of technological change, and assessments of candidate technologies and policies for climate change mitigation. PMID:23468837

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

Effect of Ethylene Inhibitors on Quality Attributes of Apricot cv. Modesto and Patterson during Storage Efecto de los Inhibidores de Etileno sobre Atributos de Calidad de Damascos, Variedades Modesto y Patterson durante Almacenamiento

Full Text Available Apricot (Prunus armeniaca L. fruit are highly susceptible to flesh softening, loss of flavor and fruit decay, particularly during postharvest storage. Most of these quality changes observed during fruit ripening are under ethylene regulation. We performed a study with the objective of determining the effect of 1-methylcyclopropene (1-MCP and aminoethoxyvinylglycine (AVG applications on quality attributes of Modesto and Patterson apricot cultivars. 1-MCP was applied at a rate of 1000 and 10 000 nL L-1 of SmartFresh™, and AVG at a rate 100 and 1000 mg L-1 of Retain®. Quality evaluations were performed after 20 and 30 days of cold storage and after a shelf-life period of 3-4 days at 20 °C. In general, both ethylene inhibitors were effective in reducing the ethylene production rate, especially in Patterson. Fruit softening and color development showed ethylene-dependent behavior, with significant reductions for both varieties in fruit treated with 1-MCP and AVG. On the other hand, soluble solids concentration and titratable acidity showed an ethylene-independent pattern, i.e. they were not affected by ethylene inhibitors applications. Among volatile compounds identified, esters and aldehydes showed ethylene-dependent behavior in both varieties. On the other hand, alcohols and terpenes were not affected by ethylene inhibition, suggesting ethylene-independent behavior.El damasco (Prunus armeniaca L. es muy susceptible al ablandamiento de la pulpa, pérdida de sabor y pudriciones, especialmente durante postcosecha.

Sewall Wright's equation Deltaq=(q(1-q) partial differentialw/ partial differentialq)/2w.

Science.gov (United States)

Edwards, A W

2000-02-01

An equation of Sewall Wright's expresses the change in the frequency of an allele under selection at a multiallelic locus as a function of the gradient of the mean fitness "surface" in the direction in which the relative proportions of the other alleles do not change. An attempt to derive this equation using conventional vector calculus shows that this description leads to a different equation and that the purported gradient in Wright's equation is not a gradient of the mean fitness surface except in the diallelic case, where the two equations are the same. It is further shown that if Fisher's angular transformation is applied to the diallelic case the genic variance is exactly equal to one-eighth of the square of the gradient of the mean fitness with respect to the transformed gene frequency.

LA ESTRUCTURA ORGÁNICA EN LOS RASCACIELOS DE FRANK LLOYD WRIGHT / The organic structure in the skyscrapers of Frank Lloyd Wright

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

Invertendo a “Passagem Atlântica”: O “regresso” de Richard Wright a África

Directory of Open Access Journals (Sweden)

Ana Luísa Saraiva

2012-10-01

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.

Neuroblastoma - remembering the three physicians who described it a century ago: James Homer Wright, William Pepper, and Robert Hutchison

International Nuclear Information System (INIS)

Rothenberg, Alexis B.; Berdon, Walter E.; D'Angio, Giulio J.; Yamashiro, Darrell J.; Cowles, Robert A.

2009-01-01

Neuroblastoma is often widespread at the time of diagnosis. Three physicians between 1900 and 1910 played an important role in the pathologic definition of neuroblastoma and its route of spread in relation to the age of the patient. These findings eventually led to the advances in treatment and decreased morbidity of today. In 1910 James Homer Wright was the first to recognize the tumor as being of primitive neural cell origin, calling it neuroblastoma and emphasizing the bundle of cells termed rosettes. While Wright recognized the neural nature of the tumor, the authors of previous reports had described its two distinct patterns of spread. In 1901 William Pepper published a series of infants with massive hepatic infiltration associated with adrenal tumors without spread to bone, and in 1907 Robert Grieve Hutchison reported his experience with a similar pathologic process in older infants and children who had orbital and skull metastases. Wright's valuable unifying concept served to tie together the descriptions of Pepper and Hutchison. A century later the names of these physicians should be remembered - Wright, who defined the adrenal tumor as of primitive neural origin, Pepper for his clinically accurate report of massive liver involvement in the infant, and Hutchison for describing the propensity of the tumor to spread to bone in older children.

Full Text Available Within his large architectural production, Frank Lloyd Wright had the opportunity to experiment with the timber industrialization, linking a traditional material with the modern sense of architecture. Wood and Frank Lloyd Wright are inseparable from the balloon frame system, a system which he will use at his first housing and through which he will materialize the spatial decomposition concept. The research on the particular American System-Built Houses case will serve to show the earliest experiences of Wright with the industry, whose conclusions he would use for subsequent researches on prefabrication.

SiDIVS: Simple Detection of Inductive Vehicle Signatures with a Multiplex Resonant Sensor

2016-08-01

Full Text Available This work provides a system capable of obtaining simultaneous inductive signatures of vehicles traveling on a roadway with minimal cost. Based on Time-Division Multiplexing (TDM with multiple oscillators, one for each inductive loop, the proposed system detects the presence of vehicles by means of a shift in the oscillation period of the selected loop and registers the signature of the detected vehicles by measuring the duration of a fixed number of oscillator pulses. In order to test the system in an actual environment, we implement a prototype that we denote as SiDIVS (Simple Detection of Inductive Vehicle Signatures and acquire different vehicle inductive signatures under real scenarios. We also test the robustness of the detector by simulating the effect of noise on the signature acquisition.

Analysis of the bioclimatic strategies used by Frank Lloyd Wright in the Jacobs I house

Directory of Open Access Journals (Sweden)

M. Beltrán-Fernández

2017-10-01

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

Space power subsystem sizing

International Nuclear Information System (INIS)

Geis, J.W.

1992-01-01

This paper discusses a Space Power Subsystem Sizing program which has been developed by the Aerospace Power Division of Wright Laboratory, Wright-Patterson Air Force Base, Ohio. The Space Power Subsystem program (SPSS) contains the necessary equations and algorithms to calculate photovoltaic array power performance, including end-of-life (EOL) and beginning-of-life (BOL) specific power (W/kg) and areal power density (W/m 2 ). Additional equations and algorithms are included in the spreadsheet for determining maximum eclipse time as a function of orbital altitude, and inclination. The Space Power Subsystem Sizing program (SPSS) has been used to determine the performance of several candidate power subsystems for both Air Force and SDIO potential applications. Trade-offs have been made between subsystem weight and areal power density (W/m 2 ) as influenced by orbital high energy particle flux and time in orbit

Supporting the underdog: feminism, animal rights and citizenship in the work of Alice Morgan Wright and Edith Goode.

2000-01-01

In this article, the author examines the overlap between feminism and animal causes, particularly through the lives of two women, the sculptor, Alice Morgan Wright (1881-1975), and her friend, Edith Goode (1882-1970). Feminism and animal causes had connections in the late nineteenth century, particularly in campaigns to abolish vivisection. Wright and Goode held to these politics throughout their lives, and were "precursors of a generation yet to come" who would argue the connections - as many ecofeminists do today. Both women were involved in suffrage campaigns, and continued to be involved in women's organisations such as the National Woman's Party. They were, however, opposed to all injustice, including human mistreatment of animals. Feminism was, to Wright and Goode, part of a wider set of problems; animal cruelty reflected a greater barbarism leading to mistreatment of humans. Accordingly, they actively campaigned for legislation to protect animals and the environment, and lobbied the fledgling United Nations to include such measures. That challenge to the United Nations represented a unique attempt to bring animals into citizenship' a move being made again today, through initiatives such as the Great Ape Project.

Decentralizing constrained-efficient allocations in the Lagos–Wright pure currency economy

Bajaj, Ayushi; Hu, Tai Wei; Rocheteau, Guillaume; Silva, Mario Rafael

2017-01-01

This paper offers two ways to decentralize the constrained-efficient allocation of the Lagos–Wright (2005) pure currency economy. The first way has divisible money, take-it-or-leave-it offers by buyers, and a transfer scheme financed by money creation. If agents are sufficiently patient, the first best is achieved for finite money growth rates. If agents are impatient, the equilibrium allocation approaches the constrained-efficient allocation asymptotically as the money growth rate tends to i...

Darwinism after Mendelism: the case of Sewall Wright's intellectual synthesis in his shifting balance theory of evolution (1931).

Science.gov (United States)

Hodge, Jonathan

2011-03-01

Historians of science have long been agreeing: what many textbooks of evolutionary biology say, about the histories of Darwinism and the New Synthesis, is just too simple to do justice to the complexities revealed to critical scholarship and historiography. There is no current consensus, however, on what grand narratives should replace those textbook histories. The present paper does not offer to contribute directly to any grand, consensual, narrational goals; but it does seek to do so indirectly by showing how, in just one individual case, details of intellectual biography connect with big picture issues. To this end, I examine here how very diverse scientific and metaphysical commitments were integrated in Sewall Wright's own personal synthesis of biology and philosophy. Taking as the decisive text the short final section of Wright's long 1931 paper on 'Evolution in Mendelian populations,' I examine how his shifting balance theory (SBT) related to his optimum breeding strategy research, his physiological genetics, his general theory of homogenising and heterogenesing causation and his panpsychist view of mind and matter; and I discuss how understanding these relations can clarify Wright's place in the longue durée of evolutionary thought.

Investigation of the Stress Intensity Limits of ASME Section III Div.5 for Structure Design Criteria of SFR Fuel Assembly

Energy Technology Data Exchange (ETDEWEB)

These affect the mechanical design of the fuel assembly components. And thus, appropriate structural design criteria should also be chosen to incorporate the specific design conditions of the SFR fuel assemblies. Among them, the temperature is one of the most crucial conditions to be concerned because the sodium coolant temperature is normally more than 500ºC which is much higher than that of the LWR (< 350ºC). This implies that a thermal creep should be significantly considered in the SFR fuel assembly mechanical design. In addition to the high temperature condition, an irradiation swelling is also an important behavior that the SFR fuel assembly material should accommodate. To incorporate the temperature and irradiation impacts, the material of the fuel assembly components is presently determined to be made of HT-9, the ferriticmartensitic steel. In this paper, the ASME Sec. III Div. 5 (referred to as ‘Div. 5’ hereinafter), which was developed for a ‘high temperature reactor’, is considered as one of the structural design criteria for the mechanical design of SFR fuel assemblies. In this paper, the stress intensity limits, S{sub m} and S{sub t} of HT-9 were built for the structural criteria of an SFR fuel assembly. S{sub m} is obtained from the ultimate strength. As for S{sub t}, it is more complicated because of its dependency of time duration in addition to temperature. Following the definition of S{sub mt}, the method in the ASME Sec. III Div. 1, Subsec. NH was consulted. We found that the Sm is adopted as S{sub mt} under the temperature about 470ºC which is relatively low temperature range and over 470ºC with relatively short time duration as 1000 hours. And the S{sub t} is adopted as Smt at over 470ºC and long time duration over 34800 hours, and over 520ºC and 10{sup 4} hours too. And at over 570ºC and 1000 hours, and at over 630ºC and 100 hours, S{sub t} is also adopted for S{sub mt}.

A taxonomic revision of the genus Primnoisis Studer [& Wright], 1887 (Coelenterata: Octocorallia: Isididae) using morphological and molecular data.

Science.gov (United States)

Moore, Kirrily; Alderslade, Philip; Miller, Karen

2016-02-05

A complete taxonomic revision of the genus Primnoisis (Isididae) is presented herein, based on original type material of all nominal species and additional specimens from deep-water surveys in sub-temperate and Antarctic waters. A multi-disciplinary approach was used combining morphological characteristics such as colonial branching patterns, polyp structure, sclerite form and arrangement, together with phylogenetic reconstructions using two mitochondrial gene regions (mtMutS and igr1-cox1). The genus Primnoisis is retained with 7 of the 8 nominal species validated (P. antarctica Wright & Studer, 1889, P. rigida Wright & Studer, 1889, P. ambigua Wright & Studer, 1889, P. delicatula Hickson, 1907, P. fragilis Kükenthal, 1912, P. formosa Gravier, 1913 and P. mimas Bayer & Stefani, 1987), with the eighth (P. sparsa Wright & Studer, 1889), synonymised with P. antarctica. In addition, the species Mopsea gracilis Gravier, 1913 is reassigned to Primnoisis and an additional five new species are described (P. chatham n. sp., P. erymna n. sp., P. millerae n. sp., P. niwa n. sp. and P. tasmani n. sp). Most of the species fell into two clear groups, defined both by morphology and genetic grouping, for which two new sub-genera are proposed (P. (Primnoisis) n. subg. and P. (Delicatisis) n. subg.). Three species, P. ambigua, P. mimas and P. tasmani, could not be placed reliably in either sub-genus due to distinctive morphological features or genetic dissimilarity. It was not possible to confirm the monophyly of the genus due to unresolved relationships with the closely related genus Notisis Gravier, 1913 and an undescribed genus of Mopseinae.

2012-12-01

Full Text Available The Italian forest sites of FunDivEUROPE: a new FP7 project on the functional significance of forest biodiversity in Europe. FunDivEUROPE is a new project aiming at a deeper understanding of the role of forest diversity on ecosystem functions and service provisioning for society. This project combines three scientific platforms: experimental, exploratory and inventory. The exploratory platform is based on the observation of a broad range of properties, traits and ecological processes on a network of ca. 240 natural forest sites representing a gradient of tree species diversity in six focal regions of Europe (Spain, Italy, Germany, Poland, Finland and Romania. The Italian sites are located on the hills of central and Southern Tuscany and represent the category “thermophilous deciduous forest”. Almost one year of fieldwork was needed to select and characterize 36 plots measuring 30 x 30 m. Selection was based on criteria concerning tree mixtures and richness, structural parameters and main environmental variables. The main features of these sites are synthetically presented in this paper together with a short description of the project structure and scope. The aim is also to enhance dissemination of the potential implications for a sustainable forest management in Italy.

Gildea, Richard J; Winter, Graeme

2018-05-01

Combining X-ray diffraction data from multiple samples requires determination of the symmetry and resolution of any indexing ambiguity. For the partial data sets typical of in situ room-temperature experiments, determination of the correct symmetry is often not straightforward. The potential for indexing ambiguity in polar space groups is also an issue, although methods to resolve this are available if the true symmetry is known. Here, a method is presented to simultaneously resolve the determination of the Patterson symmetry and the indexing ambiguity for partial data sets. open access.

Resumen

El artículo consiste en una descripción comparada de dos edificios: Monticello ‐la casa que Thomas Jefferson construyó para sí mismo en Virginia‐ y Taliesin ‐la casa y estudio de Frank Lloyd Wright en Wisconsin‐. El texto estudia en primer lugar las fuentes arquitectónicas y la evolución del proyecto de Monticello, para centrarse después en la explicación de Taliesin. Hay una cierta similitud en el modo en que Monticello y las casas de  Wright ‐en concreto la Ward Willitts‐ se extienden  horizontalmente en el terreno y, volviendo a Taliesin, la tesis  principal del texto es que tanto la residencia de Jefferson como la de Wright se asientan sobre una colina, pero Monticello  ‘corona’ su cima, mientras que Taliesin la bordea, se sitúa como  una ‘ceja’ respecto a la misma. En definitiva, de este  último edificio se puede afirmar que es una ‘casa natural’, que  logra una plena integración entre arquitectura y naturaleza.

Abstract

This article consists of a comparative description of two buildings: Monticello, Thomas Jefferson’s residence which he  built for himself in Virginia, and Taliesin, the studio and home of Frank Lloyd Wright in Wisconsin. First, the text studies the  architectural references and evolution of the project for  Monticello, in order to later focus on explaining Taliesin. There is a certain similarity in the way that Monticello and Wright’s  houses (especially the Ward Willits House extend horizontally  across the land. The thesis of this article is that both Jefferson’s and Wright’s residences rest upon a hill, but Monticello crowns  the top while Taliesin borders it like an eyebrow. In conclusion, we can say that Taliesin is a “natural house”, which manages to fully integrate its architecture with nature

Full Text Available Patterson's paper is a condensation of two he had presented in 1988 and 1989, at conferences previous to the Carbondale Visiting Scholar Conference of 1989. He characterizes the early United States as harboring two contrasting political philosophies, agrarian versus mercantile capitalism. The agrarians, of whom Thomas Jefferson is of course the most illustrious example, followed the physiocrats in believing agricultural land to be the foundation of societies, therefore the manifest destiny of the new Republic was to conquer, and colonize more land. The mercantilists, primarily in Boston, emphasized civilization as the refinement of technologies, social order, and tastes. Both philosophies were cast in Enlightenment terms.

Rosenberg, Benjamin A.

2004-01-01

This paper describes hundreds of pendulum tests examining the beamed energy conversion efficiency of different metal targets coated with multiple liquid enhancers. Preliminary testing used a local laser with photographic paper targets, with no liquid, water, canola oil, or methanol additives. Laboratory experimentation was completed at Wright-Patterson AFB using a high-powered laser, and ballistic pendulums of aluminum, titanium, or copper. Dry targets, and those coated with water, methanol and oil were repeatedly tested in laboratory conditions. Results were recorded on several high-speed digital video cameras, and the conversion efficiency was calculated. Paper airplanes successfully launched using BEP were likewise recorded

In 1965, Intel co-founder Gordon Moore made an astonishing prediction - that every year processing power would double. Although it was corrected to a period of 18 to 24 months in 1975, this prediction has always proved accurate. Accordingly, the first Intel processor produced in 1975 was equipped with 2,300 transistors whereas the latest edition has 55 million. That means 55 million etched components crammed into an area of about a square centimetre! Today we have this extraordinary process of miniaturisation to thank for cell phones, computers and other, ever more compact electronic marvels. But where will the miniaturisation race end? What will happen when electronic etchings reach the nano-scale (a millionth of a millimetre), approaching the size of an atom? How can we even start to comprehend this nano-world, whose laws are so different from our own, human-sized world? These fascinating questions are on the programme of the 10th Wright Science Colloquia from 18 to 22 November. Five world-renowned specia...

A modified Wright-Fisher model that incorporates Ne: A variant of the standard model with increased biological realism and reduced computational complexity.

Science.gov (United States)

Zhao, Lei; Gossmann, Toni I; Waxman, David

2016-03-21

The Wright-Fisher model is an important model in evolutionary biology and population genetics. It has been applied in numerous analyses of finite populations with discrete generations. It is recognised that real populations can behave, in some key aspects, as though their size that is not the census size, N, but rather a smaller size, namely the effective population size, Ne. However, in the Wright-Fisher model, there is no distinction between the effective and census population sizes. Equivalently, we can say that in this model, Ne coincides with N. The Wright-Fisher model therefore lacks an important aspect of biological realism. Here, we present a method that allows Ne to be directly incorporated into the Wright-Fisher model. The modified model involves matrices whose size is determined by Ne. Thus apart from increased biological realism, the modified model also has reduced computational complexity, particularly so when Ne⪡N. For complex problems, it may be hard or impossible to numerically analyse the most commonly-used approximation of the Wright-Fisher model that incorporates Ne, namely the diffusion approximation. An alternative approach is simulation. However, the simulations need to be sufficiently detailed that they yield an effective size that is different to the census size. Simulations may also be time consuming and have attendant statistical errors. The method presented in this work may then be the only alternative to simulations, when Ne differs from N. We illustrate the straightforward application of the method to some problems involving allele fixation and the determination of the equilibrium site frequency spectrum. We then apply the method to the problem of fixation when three alleles are segregating in a population. This latter problem is significantly more complex than a two allele problem and since the diffusion equation cannot be numerically solved, the only other way Ne can be incorporated into the analysis is by simulation. We have

An efficient microwave-assisted extraction (MAE) technique was applied to isolate total steroid saponins from Dioscorea zingiberensis C.H. Wright (DZW). The optimal extracting conditions were established as 75% ethanol as solvent, ratio of solid/liquid 1:20 (g/ml), temperature 75 °C, irradiation power 600 W and three extraction cycles of 6 min each. Scanning electron microscopy (SEM) images of DZW processed by four different extractions provided visual evidence of the disruption effect on DZW. Diosgenin was quantified by HPLC and examined further by LC-ESI/MS after acid hydrolysis. Total steroid saponins were calculated using diosgenin from total steroid saponins. The MAE procedure was optimized, validated and compared with other conventional extraction processes. This report provides a convenient technology for the extraction and quantification of total saponins of DZW combining MAE with HPLC and LC-ESI/MS for the first time. Copyright © 2015 Elsevier Inc.

Adaptação ao divórcio e relações coparentais: contributos da teoria da vinculação Adjustment to divorce and co-parental relations: contributions from the theory of attachment

Full Text Available Neste artigo propõe-se uma contribuição da teoria da vinculação na compreensão dos processos de adaptação dos adultos ao seu divórcio e como a desvinculação ao ex-cônjuge interfere na coparentalidade pós-divórcio. Este artigo formula duas hipóteses teóricas. A primeira hipótese afirma que o divórcio, enquanto processo relacional, deve ser lido como um momento de perda que germina reacções psicológicas similares às experienciadas pelos viúvos, tal como descreve Bowlby no modelo de perda da figura de vinculação, estando dependente dos estilos de vinculação dos adultos. A segunda hipótese sustenta que a coparentalidade pós-divórcio é predita pelos estilos de vinculação e pela qualidade da reorganização da vinculação dos pais. Finalmente, uma integração teórica é apresentada, operacionalizada numa proposta de investigação futura neste domínio.In this article, it is proposed the contribution of the attachment theory for understanding adults' adjustment processes to their divorce and how detachment to ex-spouse can infer in co-parenting relationships after marital dissolution. This article makes two theoretical assumptions that focus on two dimensions. The first hypothesis states that the divorce, while a relational process, should be read as a moment of loss that germinates similar psychological reactions to those experienced by widows. Bowlby describes it in his model of loss of the attachment figure as dependent on attachment styles of divorced adults. The second hypothesis argues that the post-divorce co-parenting relationships are predicted by the attachment styles and by the quality of parents' attachment reorganization. At the end, a theoretical integration is built, based on a proposal for future research in this area.

The First Nine Months of Editing Wittgenstein - Letters from G.E.M. Anscombe and Rush Rhees to G.H. von Wright

Full Text Available The National Library of Finland (NLF and the Von Wright and Wittgenstein Archives at the University of Helsinki (WWA keep the collected correspondence of Georg Henrik von Wright, Wittgenstein’s friend and successor at Cambridge and one of the three literary executors of Wittgenstein’s Nachlass. Among von Wright’s correspondence partners, Elizabeth Anscombe and Rush Rhees are of special interest to Wittgenstein scholars as the two other trustees of the Wittgenstein papers. Thus, von Wright’s collections held in Finland promise to shed light on the context of decades of editorial work that made Wittgenstein’s later philosophy available to all interested readers. In this text, we present the letters which von Wright received from Anscombe and Rhees during the first nine months after Wittgenstein’s death. This correspondence provides a vivid picture of the literary executors as persons and of their developing relationships. The presented letters are beautiful examples of what the correspondence as a whole has to offer; it depicts – besides facts of editing – the story of three philosophers, whose conversing voices unfold the human aspects of inheriting Wittgenstein’s Nachlass. Their story does not only deal with editing the papers of an eminent philosopher, but with the attempt to do justice to the man they knew, to his philosophy and to his wishes for publication.

We investigate an above-ground population following a Fisher-Wright model with selection coupled with a deterministic seed bank assuming the length of the seed bank is kept constant and the number of seeds is large. To assess the combined impact of seed banks and selection on genetic diversity, we derive a general diffusion model. The applied techniques outline a path of approximating a stochastic delay differential equation by an appropriately rescaled stochastic differential equation. We compute the equilibrium solution of the site-frequency spectrum and derive the times to fixation of an allele with and without selection. Finally, it is demonstrated that seed banks enhance the effect of selection onto the site-frequency spectrum while slowing down the time until the mutation-selection equilibrium is reached.

Osteosarcoma (OSA) is a common primary bone tumor in dogs. Demonstration of alkaline phosphatase (ALP) reactivity by tumor cells on unstained slides is useful in differentiating osteosarcoma from other types of sarcoma. However, unstained slides are not always available. The objectives of this study were to evaluate the diagnostic utility of detecting ALP expression in differentiating osteosarcoma from other sarcomas in dogs using cytologic material previously stained with Wright-Giemsa stain and to assess the sensitivity and specificity of ALP expression for diagnosing osteosarcoma using a specific protocol. Archived aspirates of histologically confirmed sarcomas in dogs that had been previously stained with Wright-Giemsa stain were treated with 5-bromo, 4-chloro, 3-indolyl phosphate/nitroblue tetrazolium (BCIP/NBT) as a substrate for ALP. Cells were evaluated for expression of ALP after incubation with BCIP/NBT for 1 hour. Sensitivity and specificity of ALP expression for diagnosis of OSA were calculated. In samples from 83 dogs, cells from 15/17 OSAs and from 4/66 tumors other than OSA (amelanotic melanoma, gastrointestinal stromal tumor, collision tumor, and anaplastic sarcoma) expressed ALP. Sensitivity and specificity of ALP expression detected using BCIP/NBT substrate applied to cells previously stained with Wright-Giemsa stain for OSA were 88 and 94%, respectively. ALP expression detected using BCIP/NBT substrate applied to previously stained cells is useful in differentiating canine OSA from other mesenchymal neoplasms. © 2012 American Society for Veterinary Clinical Pathology.

An engineering code to analyze hypersonic thermal management systems

1993-01-01

Thermal loads on current and future aircraft are increasing and as a result are stressing the energy collection, control, and dissipation capabilities of current thermal management systems and technology. The thermal loads for hypersonic vehicles will be no exception. In fact, with their projected high heat loads and fluxes, hypersonic vehicles are a prime example of systems that will require thermal management systems (TMS) that have been optimized and integrated with the entire vehicle to the maximum extent possible during the initial design stages. This will not only be to meet operational requirements, but also to fulfill weight and performance constraints in order for the vehicle to takeoff and complete its mission successfully. To meet this challenge, the TMS can no longer be two or more entirely independent systems, nor can thermal management be an after thought in the design process, the typical pervasive approach in the past. Instead, a TMS that was integrated throughout the entire vehicle and subsequently optimized will be required. To accomplish this, a method that iteratively optimizes the TMS throughout the vehicle will not only be highly desirable, but advantageous in order to reduce the manhours normally required to conduct the necessary tradeoff studies and comparisons. A thermal management engineering computer code that is under development and being managed at Wright Laboratory, Wright-Patterson AFB, is discussed. The primary goal of the code is to aid in the development of a hypersonic vehicle TMS that has been optimized and integrated on a total vehicle basis.

Jones, C.

1979-01-01

Aviation related rotary (Wankel-type) engine tests, possible growth directions and relevant developments at Curtiss-Wright have been reviewed. Automotive rotary engines including stratified charge are described and flight test results of rotary aircraft engines are presented. The current 300 HP engine prototype shows basic durability and competitive performance potential. Recent parallel developments have separately confirmed the geometric advantages of the rotary engine for direct injected unthrottled stratified charge. Specific fuel consumption equal to or better than pre- or swirl-chamber diesels, low emission and multi-fuel capability have been shown by rig tests of similar rotary engine.

This report summarizes the results of Phase I of a study entitled, Low-Cost Manufacturing Of Multilayer Ceramic Fuel Cells. The work was carried out by a group called the Multilayer Fuel Cell Alliance (MLFCA) led by NexTech Materials and including Adaptive Materials, Advanced Materials Technologies (AMT), Cobb & Co., Edison Materials Technology Center, Iowa State University, Gas Technology Institute (GTI), Northwestern University, Oak Ridge National Laboratory (ORNL), Ohio State University, University of Missouri-Rolla (UMR), and Wright-Patterson Air Force Base. The objective of the program is to develop advanced manufacturing technologies for making solid oxide fuel cell components that are more economical and reliable for a variety of applications. In the Phase I effort, five approaches were considered: two based on NexTech's planar approach using anode and cathode supported variations, one based on UMR's ultra-thin electrolyte approach, and two based on AMI's co-extrusion technology. Based on a detailed manufacturing cost analysis, all of the approaches are projected to result in a significantly reduced production cost. Projected costs range from $139/kW to $179/kW for planar designs. Development risks were assessed for each approach and it was determined that the NexTech and UMR approaches carried the least risk for successful development. Using advanced manufacturing methods and a proprietary high power density design, the team estimated that production costs could be reduced to $94/kW.

Religion and politics in conflict: Paul Stuart Wright and the 1964 coup

Directory of Open Access Journals (Sweden)

Márcio Ananias Ferreira Vilela

2016-06-01

Full Text Available In this article, we seek to understand the implications of Paulo Stuart Wright´s political and religious action. Beginning with the civil and military coup of 1964, it suffered a strong reaction from majority sectors in the Presbyterian Church of Brazil that started to perceive him as a threat to the religious community and to society itself. The following period was marked by an intense political conflict in Brazil. This contributed for the person in question to be expelled from the Church, have his mandate as a state representative for Santa Catarina impeached, be exiled, live in clandestinity and, later on in the 1970s, be murdered by the organs of repression. Thus, his trajectory bears many similarities to those of others who marked the recent history of Brazil.

With the development of digital mammography, some improved benefit has been shown in women with dense breast tissue. However, the density of breast tissue continues to limit the sensitivity of conventional mammography. We discuss the development of some derivative digital technologies, primarily digital breast tomosynthesis, and their strengths, weaknesses, and potential patient impact.

Hofrichter, Julian; Tran, Tat Dat

2017-01-01

The present monograph develops a versatile and profound mathematical perspective of the Wright--Fisher model of population genetics. This well-known and intensively studied model carries a rich and beautiful mathematical structure, which is uncovered here in a systematic manner. In addition to approaches by means of analysis, combinatorics and PDE, a geometric perspective is brought in through Amari's and Chentsov's information geometry. This concept allows us to calculate many quantities of interest systematically; likewise, the employed global perspective elucidates the stratification of the model in an unprecedented manner. Furthermore, the links to statistical mechanics and large deviation theory are explored and developed into powerful tools. Altogether, the manuscript provides a solid and broad working basis for graduate students and researchers interested in this field.

Full Text Available This case report describes the esthetic and functional rehabilitation of a female patient in her mid forties having Class II Div 1 malocclusion, anterior open bite and multiple missing molars, with orthodontics and implant prosthodontics. The patient had bilaterally missing upper first and third molars and lower first and second molars. Orthodontic treatment using skeletal anchorage was performed to retract and align the upper anteriors and correct the open bite. In the upper arch, first molar spaces were closed and no prosthesis was needed. In the lower arch, the anteriors and premolars were aligned and implants were placed bilaterally to replace the missing molars and provide proper occlusion with the upper posteriors. Significant improvement in the occlusion, smile and facial esthetics was achieved. This article highlights the importance of an interdisciplinary team approach for providing optimum treatment to many adult patients.

Aulich, Ted; Sharma, Ramesh

2012-07-01

The Energy and Environmental Research Center (EERC), in partnership with the U.S. Department of Energy (DOE) and Accelergy Corporation, an advanced fuels developer with technologies exclusively licensed from ExxonMobil, undertook Subtask 3.9 to design, build, and preliminarily operate a bench-scale direct coal liquefaction (DCL) system capable of converting 45 pounds/hour of pulverized, dried coal to a liquid suitable for upgrading to fuels and/or chemicals. Fabrication and installation of the DCL system and an accompanying distillation system for off-line fractionation of raw coal liquids into 1) a naphtha middle distillate stream for upgrading and 2) a recycle stream was completed in May 2012. Shakedown of the system was initiated in July 2012. In addition to completing fabrication of the DCL system, the project also produced a 500-milliliter sample of jet fuel derived in part from direct liquefaction of Illinois No. 6 coal, and submitted the sample to the Air Force Research Laboratory (AFRL) at Wright Patterson Air Force Base, Dayton, Ohio, for evaluation. The sample was confirmed by AFRL to be in compliance with all U.S. Air Force-prescribed alternative aviation fuel initial screening criteria.

Shuffled Frog Leaping Algorithm for Preemptive Project Scheduling Problems with Resource Vacations Based on Patterson Set

Directory of Open Access Journals (Sweden)

Yi Han

2013-01-01

Full Text Available This paper presents a shuffled frog leaping algorithm (SFLA for the single-mode resource-constrained project scheduling problem where activities can be divided into equant units and interrupted during processing. Each activity consumes 0–3 types of resources which are renewable and temporarily not available due to resource vacations in each period. The presence of scarce resources and precedence relations between activities makes project scheduling a difficult and important task in project management. A recent popular metaheuristic shuffled frog leaping algorithm, which is enlightened by the predatory habit of frog group in a small pond, is adopted to investigate the project makespan improvement on Patterson benchmark sets which is composed of different small and medium size projects. Computational results demonstrate the effectiveness and efficiency of SFLA in reducing project makespan and minimizing activity splitting number within an average CPU runtime, 0.521 second. This paper exposes all the scheduling sequences for each project and shows that of the 23 best known solutions have been improved.

1993-01-01

The research for this thesis involved the application of two-photon allowed laser-induced fluorescence (TALIF) to the study of atomic hydrogen and oxygen production in industrial scale radio-frequency and microwave plasma discharge apparatus. Absolute atomic hydrogen concentration profiles were measured in a Gaseous Electronics Conference Reference Cell installed at Wright-Patterson AFB, Ohio operating with a simple H 2 discharge. Two-dimensional atomic hydrogen concentration profiles were also measured in an ASTEX HPMM microwave plasma diamond deposition reactor during actual diamond growth. In addition absolute atomic oxygen concentrations were measured in the ASTEX system. Particular attention as paid to refining the concentration calibration technique and in determining a correction to account for the collisional quenching of excited state fluorescence in high pressure gases

Evolutionary Game Dynamics in a Fitness-Dependent Wright-Fisher Process with Noise

International Nuclear Information System (INIS)

Quan Ji; Wang Xianjia

2011-01-01

Evolutionary game dynamics in finite size populations can be described by a fitness-dependent Wright-Fisher process. We consider symmetric 2x2 games in a well-mixed population. In our model, two parameters to describe the level of player's rationality and noise intensity in environment are introduced. In contrast with the fixation probability method that used in a noiseless case, the introducing of the noise intensity parameter makes the process an ergodic Markov process and based on the limit distribution of the process, we can analysis the evolutionary stable strategy (ESS) of the games. We illustrate the effects of the two parameters on the ESS of games using the Prisoner's dilemma games (PDG) and the snowdrift games (SG). We also compare the ESS of our model with that of the replicator dynamics in infinite size populations. The results are determined by simulation experiments. (general)

The flowering of pathology as a medical discipline in Boston, 1892-c.1950: W.T. Councilman, FB Mallory, JH Wright, SB Wolbach and their descendants.

Science.gov (United States)

Louis, David N; O'Brien, Michael J; Young, Robert H

2016-09-01

During most of the nineteenth century, the discipline of pathology in Boston made substantial strides as a result of physicians and surgeons who practiced pathology on a part-time basis. The present essay tells the subsequent story, beginning in 1892, when full-time pathologists begin to staff the medical schools and hospitals of Boston. Three individuals from this era deserve special mention: William T Councilman, Frank Burr Mallory and James Homer Wright, with Councilman remembered primarily as a visionary and teacher, Mallory as a trainer of many pathologists, and Wright as a scientist. Together with S Burt Wolbach in the early-to-mid-twentieth century, these pathologists went on to train the next generation of pathologists-a generation that then populated the various hospitals that were developed in Boston in the early 1900s. This group of seminal pathologists in turn formed the diagnostically strong, academically productive, pathology departments that grew in Boston over the remainder of the twentieth century.

2007-01-01

Full Text Available Introduction: Monitoring of peak expiratory flow (PEF is recommended in numerous guidelines for management of asthma. Improvements in calibration methods have demonstrated the inaccuracy of original Wright scale of peak flowmeter. A new standard, EN 13826 that was applied to peak flowmeter was adopted on 1st September 2004 by some European countries. Correction of PEF readings obtained with old type devices for measurement is possible by Dr M. Miller’s original predictive equation. Objective. Assessment of PEF correction effect on the interpretation of measurement results and management decisions. Method. In children with intermittent (35 or stable persistent asthma (75 aged 6-16 years, there were performed 8393 measurements of PEF by Vitalograph normal-range peak flowmeter with traditional Wright scale. Readings were expressed as percentage of individual best values (PB before and after correction. The effect of correction was analyzed based on The British Thoracic Society guidelines for asthma attack treatment. Results. In general, correction reduced the values of PEF (p<0.01. The highest mean percentage error (20.70% in the measured values was found in the subgroup in which PB ranged between 250 and 350 l/min. Nevertheless, the interpretation of PEF after the correction in this subgroup changed in only 2.41% of measurements. The lowest mean percentage error (15.72%, and, at the same time, the highest effect of correction on measurement results interpretation (in 22.65% readings were in children with PB above 450 l/min. In 73 (66.37% subjects, the correction changed the clinical interpretation of some values of PEF after correction. In 13 (11.8% patients, some corrected values indicated the absence or a milder degree of airflow obstruction. In 27 (24.54% children, more than 10%, and in 12 (10.93%, more than 20% of the corrected readings indicated a severe degree of asthma exacerbation that needed more aggressive treatment. Conclusion

Antibodies to red cell antigens that are found at low frequency in the general population are rare causes of hemolytic disease of the newborn. To understand how to detect these cases, we provide a basic review of routine antenatal maternal antibody testing and report a case of a neonate with severe HDN caused by anti-Wright (anti-Wra), successfully managed with transfusion, phototherapy, and high-dose intravenous immunoglobulin. When hemolysis in a newborn is suspected in the absence of major blood group incompatibility or commonly detected maternal red cell antibodies, a direct antiglobulin test should be performed. A positive DAT should alert the clinician to the presence of maternal antibodies against low-incidence antigens. Antibodies to the Wra antigen are one such rare cause of HDN.

Investigation of the Stress Intensity Limits of ASME Section III Div.5 for Structure Design Criteria of SFR Fuel Assembly

International Nuclear Information System (INIS)

Choo, Jin-Yup; Kim, Hyung-Kyu; Cheon, Jin-Sik

2017-01-01

In this paper, the stress intensity limits, Sm and St of HT-9 were built for the structural criteria of an SFR fuel assembly. Sm is obtained from the ultimate strength. As for St, it is more complicated because of its dependency of time duration in addition to temperature. Following the definition of Smt, the method in the ASME Sec. III Div. 1, Subsec. NH was consulted. We found that the Sm is adopted as Smt under the temperature about 470 .deg. C which is relatively low temperature range and over 470 .deg. C with relatively short time duration as 1000 hours. And the St is adopted as Smt at over 470 .deg. C and long time duration over 34800 hours, and over 520 .deg. C and 104 hours too.

Design information verification for spent fuel conditioning plants and for geological repositories

International Nuclear Information System (INIS)

Myatt, J.; Ward, M.D.

1995-01-01

The disposal of spent fuel is a major option for the back-end of the nuclear fuel cycle. It will require the construction, operation and eventual closure of conditioning plants and geological repositories. Consequently, a safeguards approach including Design Information Verification (DIV) must be developed for these facilities. DIV Is the examination of a completed facility to verify that it has been built to the design declared by the operator. Although DIV takes place chiefly before a plant begins routine operation, there is a continuing interest in ensuring that the plant remains as declared. That is, that the continuity of knowledge of design information is maintained during the operational phase of the plant and also post closure if necessary. A major problem with DIV of a repository is that there will be continuous structural changes during its operational life requiring advanced or special techniques for reverification. Some of these are briefly reviewed. Furthermore, since a disposal facility is expected to be operational for several decades, new mining technology may also have an impact on the DIV methods employed. Another factor in the safeguards supervision of a repository is that when the fuel has been backfilled and/or scaled in place a reassay will be a very costly exercise. The role of DIV in such novel circumstances must, therefore, be fully considered

Applications of population genetics to animal breeding, from wright, fisher and lush to genomic prediction.

Science.gov (United States)

Hill, William G

2014-01-01

Although animal breeding was practiced long before the science of genetics and the relevant disciplines of population and quantitative genetics were known, breeding programs have mainly relied on simply selecting and mating the best individuals on their own or relatives' performance. This is based on sound quantitative genetic principles, developed and expounded by Lush, who attributed much of his understanding to Wright, and formalized in Fisher's infinitesimal model. Analysis at the level of individual loci and gene frequency distributions has had relatively little impact. Now with access to genomic data, a revolution in which molecular information is being used to enhance response with "genomic selection" is occurring. The predictions of breeding value still utilize multiple loci throughout the genome and, indeed, are largely compatible with additive and specifically infinitesimal model assumptions. I discuss some of the history and genetic issues as applied to the science of livestock improvement, which has had and continues to have major spin-offs into ideas and applications in other areas.

Full Text Available Reducing costs forces of companies to look for reserves also in field of management, support and implementation of material flow. This is connected with the optimization of costs for product distribution, which forms a significant part of the total cost of the company. In practice, it happens that making plans for distribution of materials within a distribution space is left solely to the implementers of distribution and it drivers of vehicles. As a result is uneconomic material distribution and unnecessary cost increases to his distribution. The objective of the paper is to propose a methodology for optimization of transport planning from DC Prešov to the individual Tesco units within the region that comes under this distribution centre. The methodology is based on the Clarke and Wright saving algorithm.

Application of Prigogine-Flory-Patterson theory to excess molar volume of mixtures of 1-butyl-3-methylimidazolium ionic liquids with N-methyl-2-pyrrolidinone

International Nuclear Information System (INIS)

Qi Feng; Wang Haijun

2009-01-01

The densities of two binary mixtures formed by 1-butyl-3-methylimidazolium tetrafluoroborate [bmim][BF 4 ] and 1-butyl-3-methy limidazolium hexafluorophosphate [bmim][PF 6 ] with compound N-methyl-2-pyrrolidinone have been determined over the full range of composition and range of temperature from (298.15 to 313.15) K and at atmospheric pressure using a vibrating-tube densimeter (DMA4500). Excess molar volumes, V m E , have been obtained from these experimental results, and been fitted by the fourth-order Redlich-Kister equation. From the experimental results, partial molar volumes, apparent molar volume and partial molar volumes at infinite dilution were calculated over the whole composition range. Our results show that V m E decreases slightly when temperature increases in the systems studied. The experimental results have been used to test the applicability of the Prigogine-Flory-Patterson (PFP) theory. The results have been interpreted in terms of ion-dipole interactions and structural factors of the ionic liquid and these organic molecular liquids

Introducing Darwinism to Toronto's post-1887 reconstituted medical school.

Science.gov (United States)

Court, John P M

2011-01-01

Charles Darwin's scientific paradigm was largely welcomed in Canadian academic biology and medicine, while reaction among other faculty and laypeople ranged from interest to outrage. In 1874, Ramsay Wright, a Darwinian-era biologist from Edinburgh, was appointed to the University of Toronto's Chair of Natural History. Over his 38-year career Wright integrated the evolutionary perspective into medical and biology teaching without accentuating its controversial source. He also applied the emerging German experimental research model and laboratory technology. This study identifies five categories of scientific and personal influences upon Wright through archival research on biographical sources and his writings.

As bases eleitorais de Lula e do PT: do distanciamento ao divórcio

Full Text Available O debate sobre o distanciamento entre Lula e o Partido dos Trabalhadores (PT ganhou corpo na eleição de 2006, quando a popularidade de Lula e de seu governo não se estendeu ao PT, como seria esperado. Pela primeira vez o partido não melhorou o desempenho na votação para a Câmara dos Deputados em relação à eleição anterior. Analisamos as bases eleitorais de Lula e do PT nas quatro últimas eleições para presidente e deputado federal (1994-2006, e comprovamos o distanciamento entre elas. Pesquisamos a distribuição espacial das votações ao nível do município com mapas, estatísticas e regressões espaciais. Identificamos o "descolamento" dos territórios eleitorais do candidato e do partido a cada eleição, e as regressões espaciais mediram a crescente independência espaço-temporal das votações: os coeficientes baixaram de 0,85 em 1994, para 0,15 em 2006. Houve um processo de distanciamento geossocial, no período de 1994 a 2002, e um "divórcio" entre as bases eleitorais, em 2006, quando se formaram territórios de configurações praticamente irrelacionadas.The debate about the distancing between Lula and the Workers Party (PT gained acceptance in the 2006 election, when the popularity of Lula and his government did not extend to the PT, as expected. For the first time the party did not improve performance in the voting for the Chamber of Deputies regarding the previous election. We analyzed the electoral bases of Lula and the PT in the last four elections for president and federal deputies (1994-2006, and we prove the distancing between them. We studied the spatial distribution of votes at the municipal level with maps, statistics and spatial regression. We identified the detachment of the candidate's and party's electoral territories every election, and the regressions measured the growing spatial-temporal independence of the votings: the coefficient fell from 0.85 in 1994 to 0.15 in 2006.

Hwang, T.J.; Hendrick, M.R.; Shao, H.; Hornis, H.G.; Hunt, A.T.

1998-01-01

This research used the low cost, open atmosphere combustion chemical vapor deposition (CCVD SM ) method to efficiently deposit protective coatings onto alumina fibers (3M Nextel TM 610) for use in ceramic matrix composites (CMCs). La-monazite (LaPO 4 ) and beta-alumina were the primary candidate debonding coating materials investigated. The coated fibers provide thermochemical stability, as well as desired debonding/sliding interface characteristics to the CMC. Dense and uniform La-phosphate coatings were obtained at deposition temperatures as low as 900-1000 C with minimal degradation of fibers. However, all of the β-alumina phases required high deposition temperatures and, thus, could not be applied onto the Nextel TM 610 alumina fibers. The fibers appeared to have complete and relatively uniform coatings around individual filaments when 420 and 1260 filament tows were coated via the CCVD process. Fibers up to 3 feet long were fed through the deposition flame in the laboratory of MicroCoating Technologies (MCT). TEM analyses performed at Wright-Patterson AFB on the CCVD coated fibers showed a 10-30 nm thick La-rich layer at the fiber/coating interface, and a layer of columnar monazite 0.1-1 μm thick covered with sooty carbon of <50 nm thick on the outside. A single strength test on CCVD coated fibers performed by 3M showed that the strength value fell in the higher end of data from other CVD coated samples. (orig.)

Working Group 2: Future Directions for Safeguards and Verification, Technology, Research and Development

International Nuclear Information System (INIS)

Zykov, S.; Blair, D.

2013-01-01

For traditional safeguards it was recognized that the hardware presently available is, in general, addressing adequately fundamental IAEA needs, and that further developments should therefore focus mainly on improving efficiencies (i.e. increasing cost economies, reliability, maintainability and user-friendliness, keeping abreast of continual advancements in technologies and of the evolution of verification approaches). Specific technology areas that could benefit from further development include: -) Non-destructive measurement systems (NDA), in particular, gamma-spectroscopy and neutron counting techniques; -) Containment and surveillance tools, such as tamper indicating seals, video-surveillance, surface identification methods, etc.; -) Geophysical methods for design information verification (DIV) and safeguarding of geological repositories; and -) New tools and methods for real-time monitoring. Furthermore, the Working Group acknowledged that a 'building block' (or modular) approach should be adopted towards technology development, enabling equipment to be upgraded efficiently as technologies advance. Concerning non-traditional safeguards, in the area of satellite-based sensors, increased spatial resolution and broadened spectral range were identified as priorities. In the area of wide area surveillance, the development of LIDAR-like tools for atmospheric sensing was discussed from the perspective of both potential benefits and certain limitations. Recognizing the limitations imposed by the human brain in terms of information assessment and analysis, technologies are needed that will enable the more effective utilization of all information, regardless of its format and origin. The paper is followed by the slides of the presentation. (A.C.)

1990-11-01

The installation of the Advanced Tactical Air Reconnaissance System (ATARS) in the F/A-18D(RC) presented a complex set of design challenges. At the time of the F/A-18D(RC) ATARS option exercise, the design and development of the ATARS subsystems and the parameters of the F/A-18D(RC) were essentially fixed. ATARS is to be installed in the gun bay of the F/A-18D(RC), taking up no additional room, nor adding any more weight than what was removed. The F/A-18D(RC) installation solution required innovations in mounting, cooling, and fit techniques, which made constant trade study essential. The successful installation in the F/A-18D(RC) is the result of coupling fundamental design engineering with brainstorming and nonstandard approaches to every situation. ATARS is sponsored by the Aeronautical Systems Division, Wright-Patterson AFB, Ohio. The F/A-18D(RC) installation is being funded to the Air Force by the Naval Air Systems Command, Washington, D.C.

Aerial radiological survey of the US Department of Energy's Mound Facility, Miamisburg, Ohio

International Nuclear Information System (INIS)

1978-03-01

An aerial radiological survey to measure terrestrial gamma radiation was carried out by helicopter over an area centered on Mound Facility, a 180 acre area adjacent to the southern edge of the city of Miamisburg, Ohio. This survey was part of an effort to document background radiation levels around nuclear processing and handling facilities owned or contracted by the United States Department of Energy (DOE). Survey activities were conducted and performed by EG and G for the DOE. Wright-Patterson Air Force Base served as the survey base of operations. During the survey, gamma ray data were collected over a 12.3 km 2 area by flying an east-west grid of lines spaced 61 m apart, flying slowly over several selected areas, and hovering over several spots of interest. The processed data indicated that the on-site radioactivity was primarily due to radionuclides currently being handled or processed at the Facility, and that lesser activity could be attributed to previously handled or processed nuclear materials. Off-site data showed the radioactivity to be that only due to naturally occurring radionuclides

Production and Optimization of Direct Coal Liquefaction derived Low Carbon-Footprint Transportation Fuels

2010-06-30

This report summarizes works conducted under DOE Contract No. DE-FC26-05NT42448. The work scope was divided into two categories - (a) experimental program to pretreat and refine a coal derived syncrude sample to meet transportation fuels requirements; (b) system analysis of a commercial scale direct coal liquefaction facility. The coal syncrude was derived from a bituminous coal by Headwaters CTL, while the refining study was carried out under a subcontract to Axens North America. The system analysis included H{sub 2} production cost via six different options, conceptual process design, utilities requirements, CO{sub 2} emission and overall plant economy. As part of the system analysis, impact of various H{sub 2} production options was evaluated. For consistence the comparison was carried out using the DOE H2A model. However, assumptions in the model were updated using Headwaters database. Results of Tier 2 jet fuel specifications evaluation by the Fuels & Energy Branch, US Air Force Research Laboratory (AFRL/RZPF) located at Wright Patterson Air Force Base (Ohio) are also discussed in this report.

The experiments involved 40 hearts prepared in 10% formalin solution and dissected for the retreat of LVC. The LAVC was analyzed for tendinous cords counting and the total of these cords in each heart varied from 10 to 27 and the total oriented to the commissure of valve varied from two to five cords, all coming from papilar sub-auricular and papilar sub-atrial muscles. Higher frequency was observed in hearts with three cords that were oriented to commissure. The results suggest no anatomic standardization in the amount of tendinous cords in the heart of the sheep of the Santa Inês.div>>

Arquitectura y estructura han ido siempre íntimamente ligadas, pero con la aparición del acero y el hormigón surgieron nuevas necesidades formales o estéticas. El Estilo Internacional se inclinó por separar la retícula estructural de los cerramientos. En cambio, la Escuela de Chicago forjó las bases de una arquitectura optimizada y racional. Frank Lloyd Wright, entre estas dos situaciones, optó por seguir las pautas naturales de los materiales, de forma “orgánica”, recuperan...

Full Text Available <div>Bluetongue (BT is an infectious, insect-born viral disease of ruminants. The causative agent of BT is bluetongue virus (BTV that belongs to the family Reoviridae genus Orbivirus. Insect vectors in the genus Culicoides transmit this virus. BT affects domestic and wild ruminants, however small ruminants are considered the most affected specie. The aim of the study was to detect antibodies against BTV in commercial sheep farms, of the Northeastern region of Sao Paulo State, Brazil. A total of 1002 sera samples collected from adult sheep (above 1 year-old, comprising a total of 31 farms, were screened for the presence of BTV antibodies, by agar gel immunodiffusion test (AGID and ELISA-CFS (Enzyme Linked Immunosorbent Assay – competitive solid phase, both produced by Pan American Center of FMDV. From a total of 1002 samples, 651 (65% were positive by AGID and 742 (74.1%, were positive by ELISA-CFS. These results suggest that the BTV is widespread among farms, probably causing subclinical infections.div>>

Full Text Available <div>The aim was to evaluate the LH secretion in B. indicus heifers, on the presence or absence of gonadal steroid, generating information about the mechanisms evolved on sexual maturation in Nellore heifers. LH and progesterone concentration were quantified by RIA. First ovulation was determined by plasma progesterone concentration (>1 ng/ml. Greater mean LH concentrations was observed in ovariectomized (OVX; P?0.05 compared to intact heifers (INT. Mean LH concentration increased (P?0.05 during the sexual maturation, in both intact and ovariectomized heifers. The number of peaks was higher (P?0.05 in ovariectomized heifer. The results suggest decrease in estradiol hypothalamus negative feedback during Nellore heifer’s sexual maturation. It was possible to conclude that in pre-pubertal Nellore heifers the increase on positive gonadal steroids feedback was necessary to increase LH secretion before first ovulation.div>>
