SUMMARY Sinorhizobium meliloti is a soil bacterium that invades the root nodules it induces on Medicago sativa, whereupon it undergoes an alteration of its cell cycle and differentiates into nitrogen-fixing, elongated and polyploid bacteroid with higher membrane permeability. In Caulobacter crescentus, a related alphaproteobacterium, the principal cell cycle regulator, CtrA, is inhibited by the phosphorylated response regulator DivK. The phosphorylation of DivK depends on the histidine kinase DivJ, while PleC is the principal phosphatase for DivK. Despite the importance of the DivJ in C. crescentus, the mechanistic role of this kinase has never been elucidated in other Alphaproteobacteria. We show here that the histidine kinases DivJ together with CbrA and PleC participate in a complex phosphorylation system of the essential response regulator DivK in S. meliloti. In particular, DivJ and CbrA are involved in DivK phosphorylation and in turn CtrA inactivation, thereby controlling correct cell cycle progression and the integrity of the cell envelope. In contrast, the essential PleC presumably acts as a phosphatase of DivK. Interestingly, we found that a DivJ mutant is able to elicit nodules and enter plant cells, but fails to establish an effective symbiosis suggesting that proper envelope and/or low CtrA levels are required for symbiosis.

In B.subtilis, cell division is controlled by div-genes which have been mapped on its circular chromosome. In the present work, div-mutant strains 1A316(div II), 1A317 and 1A318 (div I) were studied. These strains exhibited temperature sensitive cell division mutations. Colony morphology, cell morphology, staining behavior, growth rate and protein content of PY79 (wild type) and div-mutant strains (1A316, 1A317, 1A318) was studied at different temperatures ( 25 deg. Centi grade and 42 deg. with varying incubation periods(4, 16, 24, 48, 72,96 hrs). div-mutants differ from wild type (PY79) in colony morphology. Colony margin in PY79 was entire while in the div strains it is undulate. Staining behavior of cells as well as cell morphology i.e., cell size, cell types, formation of filaments/minicells were affected by high temperature. At higher temperature (42 deg. Centi grade), div-mutants undergo more severe lysis and degeneration as compare to wild type (PY79). Defective spores were produced by div-mutants at 25 deg. Centi grade and 42 deg. Centi grade. Tetrazolium overlay test was performed at 37 deg. Centi grade and 42 deg. Centi grade to check the spore germination ability of wild type and div-mutants. In 1A318, defective spores were produced at 37 deg. Centi grade, div-mutant was checked after 24 and 96 hrs at different temperatures (25, 37 and 42 deg. Centi grade). At all temperatures protein content were more in PY79 as compare to div-mutants. Also at 25 and 42 deg. Centi grade, protein content was more as compare to 37 deg. Centi grade. Protein contents was reduced at sporulation stages. Thus cell division mutations affect cell morphology, sporulation and germination processes in B.subtilis and thus are multifaceted mutations.

Phyto-gegographycal analysis of Divčibare
Directory of Open Access Journals (Sweden)
Popović Ivana
2005-01-01
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
2017-10-06
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.

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.

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)
Lee, Chak S. [Lawrence Livermore National Lab. (LLNL), Livermore, CA (United States); Vassilevski, Panayot S. [Lawrence Livermore National Lab. (LLNL), Livermore, CA (United States)
2016-01-15
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.

Richrd Wright: a reluctant comrade
Torres, Stela

Richard Wright's works have often been disregarded by scholars as a mere form of propaganda in which the writer pleads the cause of the Communist Party. We must admit, however, that although Wright poses questions in his novels and short stories which are political by nature (for instance, how can the black man as an oppressed, divided, unauthentic being participate effectively in his struggle for liberation from a racist society?), the alternatives he envisages seem quite unorthodox when con...

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.

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.

Sir Almroth Wright: pioneer immunologist.
Ellis, Harold
2011-03-01
This year marks the 150th anniversary of the birth of Almroth Edward Wright, whose pioneer work in immunology saved countless lives, especially in the First World War, but whose name and work are all but forgotten today. 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.

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

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.

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.
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.

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.

Single and simultaneous binary mergers in Wright-Fisher genealogies.
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.

A weak Galerkin least-squares finite element method for div-curl systems
Li, Jichun; Ye, Xiu; Zhang, Shangyou
2018-06-01
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.

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.

The Wright Science Colloquia Entering the Nano-World
2002-01-01
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.

Passion play: Will Wright and games for science learning
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.

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.

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

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 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.

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

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 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
Nagy, Béla; Farmer, J. Doyne; Bui, Quan M.; Trancik, Jessika E.
2013-01-01
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

Digital Documentation of Frank Lloyd Wright's Masterpiece, Fallingwater
Jerome, P.; Emilio, D.
2017-08-01
Since 1988, the professional staff of Architectural Preservation Studio (APS) has been involved with the conservation of Frank Lloyd Wright's Fallingwater in Mill Run, PA. Designed and erected from 1935 to 1939 as a weekend home for the Kauffman family, the complex consists of the main house and guest house. After five years of reports and prototype repairs, we produced a two-volume master plan. Using original Frank Lloyd Wright drawings from Avery Library as background drawings, we measured every surface and reproduced the drawings in CAD, also developing elevations of every room. Stone-by-stone drawings of every flagstone floor and terrace scheduled to be lifted were also created using overlapping film photography that was assembled into a photo mosaic. By 2005, we designed, administered and completed a four-phase exterior restoration, with the paint-stripping and repainting of interior rooms being performed during the brief winter period when the building is closed to the public on an ongoing basis. In 2016, we were invited back to the site to review conditions and advise on routine maintenance. At that time we proposed to re-document the buildings, this time using laser-scanning. Laser-scanning of the exterior was performed in May of 2016, and of the interior in March 2017, each over the course of four days. This paper will make a comparison between manual and digital techniques in terms of Fallingwater's documentation.

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

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.

During the spring and summer months of 1987, the Aero Propulsion Laboratory of the Air Force Wright Aeronautical Laboratories, Wright-Patterson AFB, Ohio in cooperation with the Air Force Space Technology Center at Kirtland AFB, New Mexico, undertook an initiative to develop a Strategic Plan for Space Power Technology Development. The initiative was called SPT21, Space Power Technology for the Twenty-First Century. The planning process involved the participation of other Government organizations (U.S. Army, Navy, DOE and NASA) along with major aerospace companies and universities. Following an SPT21 kickoff meeting on 28 May 1987, detailed strategic planning was accomplished through seven (7) Space Power Technology Discipline Workshops commencing in June 1987 and concluding in August 1987. Technology Discipline Workshops were conducted in the following areas: (1) Solar Thermal Dynamic Power Systems (2) Solar Photovoltaic Cells and Arrays (3) Thermal Management Technology (4) Energy Storage Technology (5) Nuclear Power Systems Technology (6) Power Conditioning, Distribution and Control and (7) Systems Technology/Advanced Concepts. This technical paper summarizes the planning process and describes the salient findings and conclusions of the workshops

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.

SiDIVS: Simple Detection of Inductive Vehicle Signatures with a Multiplex Resonant Sensor
Directory of Open Access Journals (Sweden)
José J. Lamas-Seco
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.

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.

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...

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.

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 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.

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.

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

Ground water is the primary source of water in the Wright-Patterson Air Force Base area. The aquifer consists of glacial sands and gravels that fill a buried bedrock-valley system. Consolidated rocks in the area consist of poorly permeable Ordovician shale of the Richmondian stage, in the upland areas, the Brassfield Limestone of Silurian age. The valleys are filled with glacial sediments of Wisconsinan age consisting of clay-rich tills and coarse-grained outwash deposits. Estimates of hydraulic conductivity of the shales based on results of displacement/recovery tests range from 0.0016 to 12 feet per day; estimates for the glacial sediments range from less than 1 foot per day to more than 1,000 feet per day. Ground water flow from the uplands towards the valleys and the major rivers in the region, the Great Miami and the Mad Rivers. Hydraulic-head data indicate that ground water flows between the bedrock and unconsolidated deposits. Data from a gain/loss study of the Mad River System and hydrographs from nearby wells reveal that the reach of the river next to Wright-Patterson Air Force Base is a ground-water discharge area. A steady-state, three-dimensional ground-water-flow model was developed to simulate ground-water flow in the region. The model contains three layers and encompasses about 100 square miles centered on Wright-Patterson Air Force Base. Ground water enters the modeled area primarily by river leakage and underflow at the model boundary. Ground water exits the modeled area primarily by flow through the valleys at the model boundaries and through production wells. A model sensitivity analysis involving systematic changes in values of hydrologic parameters in the model indicates that the model is most sensitive to decreases in riverbed conductance and vertical conductance between the upper two layers. The analysis also indicates that the contribution of water to the buried-valley aquifer from the bedrock that forms the valley walls is about 2 to 4

The Wright Science Colloquia - Entering the Nano-World

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?

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.

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.

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.

Fisher-Wright model with deterministic seed bank and selection.
Koopmann, Bendix; Müller, Johannes; Tellier, Aurélien; Živković, Daniel
2017-04-01
Seed banks are common characteristics to many plant species, which allow storage of genetic diversity in the soil as dormant seeds for various periods of time. 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.

A review of Curtiss-Wright rotary engine developments with respect to general aviation potential
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.

Application of software technology to a future spacecraft computer design
Labaugh, R. J.
1980-01-01
A study was conducted to determine how major improvements in spacecraft computer systems can be obtained from recent advances in hardware and software technology. Investigations into integrated circuit technology indicated that the CMOS/SOS chip set being developed for the Air Force Avionics Laboratory at Wright Patterson had the best potential for improving the performance of spaceborne computer systems. An integral part of the chip set is the bit slice arithmetic and logic unit. The flexibility allowed by microprogramming, combined with the software investigations, led to the specification of a baseline architecture and instruction set.

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.

Information geometry and population genetics the mathematical structure of the Wright-Fisher model
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.

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)

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.

We introduce a simple model representing the underlying trade-off - between investing enough effort in any one project to spur rapid progress, and diversifying effort over many projects simultaneously to hedge against failure. We use stochastic experience curves to model the idea that investing more in a technology reduces its unit costs, and we use a mean-variance objective function to unders...

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.

An environmental investigation of ground water conditions has been undertaken at Wright-Patterson Air Force Base (WPAFB), Ohio to obtain data to assist in the evaluation of a potential removal action to prevent, to the extent practicable, migration of the contaminated ground water across Base boundaries. Field investigations were limited to the central section of the southwestern boundary of Area C and the Springfield Pike boundary of Area B. Further, the study was limited to a maximum depth of 150 feet below grade. Three primary activities of the field investigation were: (1) installation of 22 monitoring wells, (2) collection and analysis of ground water from 71 locations, (3) measurement of ground water elevations at 69 locations. Volatile organic compounds including trichloroethylene, perchloroethylene, and/or vinyl chloride were detected in concentrations exceeding Maximum Contaminant Levels (MCL) at three locations within the Area C investigation area. Ground water at the Springfield Pike boundary of Area B occurs in two primary units, separated by a thicker-than-expected clay layers. One well within Area B was determined to exceed the MCL for trichloroethylene.

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.

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. And at over 570 .deg. C and 1000 hours, and at over 630 .deg. C and 100 hours, St is also adopted for Smt. To use the present result as design criteria, a stringent examination needs to be carried out, because those are calculated from the formulae of HT-9 without an experimental validation. Therefore, an experimental work on the mechanical properties of HT-9 will be necessary.

International Nuclear Information System (INIS)
Myatt, J.; Ward, M.D.

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

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.

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

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.

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.)

An environmental investigation of ground water conditions has been undertaken at Wright-Patterson Air Force Base (WPAFB), Ohio to obtain data to assist in the evaluation of a potential removal action to prevent, to the extent practicable, migration of the contaminated ground water across Base boundaries. Field investigations were limited to the central section of the southwestern boundary of Area C and the Springfield Pike boundary of Area B. Further, the study was limited to a maximum depth of 150 feet below grade. Three primary activities of the field investigation were: (1) installation of 22 monitoring wells, (2) collection and analysis of ground water from 71 locations, (3) measurement of ground water elevations at 69 locations. Volatile organic compounds including trichloroethylene, perchloroethylene, and/or vinyl chloride were detected in concentrations exceeding Maximum Contaminant Levels (MCL) at three locations within the Area C investigation area. Ground water at the Springfield Pike boundary of Area B occurs in two primary units, separated by a thicker-than-expected clay layers. One well within Area B was determined to exceed the MCL for trichloroethylene.

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>

Full Text Available Alzheimer’s disease (AD is characterized by a progressive cognitive decline and believed to be driven by the self-aggregation of amyloid-β (Aβ peptide into oligomers and fibrils that accumulate as senile plaques. It is widely accepted that microglia-mediated inflammation is a significant contributor to disease pathogenesis; however, different microglia phenotypes were identified along AD progression and excessive Aβ production was shown to dysregulate cell function. As so, the contribution of microglia to AD pathogenesis remains to be elucidated. In this study, we wondered if isolated microglia cultured for 16 days in vitro (DIV would react differentially from the 2 DIV cells upon treatment with 1000 nM Aβ1–42 for 24 h. No changes in cell viability were observed and morphometric alterations associated to microglia activation, such as volume increase and process shortening, were obvious in 2 DIV microglia, but less evident in 16 DIV cells. These cells showed lower phagocytic, migration and autophagic properties after Aβ treatment than the 2 DIV cultured microglia. Reduced phagocytosis may derive from increased CD33 expression, reduced triggering receptor expressed on myeloid cells 2 (TREM2 and milk fat globule-EGF factor 8 protein (MFG-E8 levels, which were mainly observed in 16 DIV cells. Activation of inflammatory mediators, such as high mobility group box 1 (HMGB1 and pro-inflammatory cytokines, as well as increased expression of Toll-like receptor 2 (TLR2, TLR4 and fractalkine/CX3C chemokine receptor 1 (CX3CR1 cell surface receptors were prominent in 2 DIV microglia, while elevation of matrix metalloproteinase 9 (MMP9 was marked in 16 DIV cells. Increased senescence-associated β-galactosidase (SA-β-gal and upregulated miR-146a expression that were observed in 16 DIV cells showed to increase by Aβ in 2 DIV microglia. Additionally, Aβ downregulated miR-155 and miR-124, and reduced the CD11b+ subpopulation in 2 DIV microglia, while

2009-01-01
National Institute for Inter-disciplinary Science and Technology (NIIST), Council of Scientific and Industrial Research, Trivandrum (formerly Regional Research Laboratory) has accomplished a DAE-BRNS project with Raja Ramanna Centre for Advanced Technology (RRCAT) as principal collaborator for the development of high temperature superconductor (HTS) current leads. These HTS current leads have self-field critical currents (Ic) ranging from 50 A to 1000 A at liquid nitrogen (LN 2 ) temperature. These HTS are made out of silver sheathed Bismuth Strontium Calcium Copper Oxide (BSCCO-2223), for direct application in superconducting (SC) systems involving transportation of high electric currents from power sources at room temperature to superconducting devices at cryogenic temperatures. RRCAT has participated in this project by testing and evaluation of these HTS current leads and carried out actual load trials. In this paper, we will describe the HTS testing setup, tests performed with their testing procedure and the test results. The testing of these HTS has been done with joint effort of Materials Advanced Accelerator Science and Cryogenics Div. and Superconducting Technology Lab (SCT Lab), Advanced Accelerator Module Development Div., using the test facility available at the SCT Lab.

Characterization of Early Cortical Neural Network ...
We examined the development of neural network activity using microelectrode array (MEA) recordings made in multi-well MEA plates (mwMEAs) over the first 12 days in vitro (DIV). In primary cortical cultures made from postnatal rats, action potential spiking activity was essentially absent on DIV 2 and developed rapidly between DIV 5 and 12. Spiking activity was primarily sporadic and unorganized at early DIV, and became progressively more organized with time in culture, with bursting parameters, synchrony and network bursting increasing between DIV 5 and 12. We selected 12 features to describe network activity and principal components analysis using these features demonstrated a general segregation of data by age at both the well and plate levels. Using a combination of random forest classifiers and Support Vector Machines, we demonstrated that 4 features (CV of within burst ISI, CV of IBI, network spike rate and burst rate) were sufficient to predict the age (either DIV 5, 7, 9 or 12) of each well recording with >65% accuracy. When restricting the classification problem to a binary decision, we found that classification improved dramatically, e.g. 95% accuracy for discriminating DIV 5 vs DIV 12 wells. Further, we present a novel resampling approach to determine the number of wells that might be needed for conducting comparisons of different treatments using mwMEA plates. Overall, these results demonstrate that network development on mwMEA plates is similar to

The aim of this study is to test the effects of neo-Marxian social class and potential mediators such as labor market position, work organization, material deprivation, and health behaviors on all-cause mortality. The authors use longitudinal data from the Barcelona 2000 Health Interview Survey (N=7526), with follow-up interviews through the municipal census in 2008 (95.97% response rate). Using data on relations of property, organizational power, and education, the study groups social classes according to Wright's scheme: capitalists, petit bourgeoisie, managers, supervisors, and skilled, semi-skilled, and unskilled workers. Findings indicate that social class, measured as relations of control over productive assets, is an important predictor of mortality among working-class men but not women. Workers (hazard ratio = 1.60; 95% confidence interval, 1.10-2.35) but also managers and small employers had a higher risk of death compared with capitalists. The extensive use of conventional gradient measures of social stratification has neglected sociological measures of social class conceptualized as relations of control over productive assets. This concept is capable of explaining how social inequalities are generated. To confirm the protective effect of the capitalist class position and the "contradictory class location hypothesis," additional efforts are needed to properly measure class among low-level supervisors, capitalists, managers, and small employers.

The United States Air Force has had a long standing interest in thermionic space power dating back to the early 1960s when a heat pipe cooled thermionic converter was demonstrated through work at the predecessor to Wright Laboratory (WL). With the exception of the short hiatus in the mid-70s, Air Force thermionics work at Wright Laboratory has continued to the present time with thermionic technology programs including the burst power thermionic phase change concepts, heat pipe cooled planar diodes, and advanced in-core concept developments such as composite materials, insulators and oxygenation. The Advanced Thermionics Initiative (ATI) program was organized to integrate thermionic technology advances into a converter suitable for in-core reactor applications in the 10 to 40 kWe power range. As an advanced thermionics technology program, the charter and philosophy of the ATI program is to provide the needed advanced converter concepts in support of national thermionic space power programs

Wild kernels for higher K-theory of division and semi-simple algebras
International Nuclear Information System (INIS)
Quo Xuejun; Kuku, Aderemi
2003-06-01
Let Σ be a semi-simple algebra over a number field F. In this paper, we prove that for all n ≥ 0, the wild kernel WK n (Σ):Ker(K n (Σ) → Π finiteυ K n (Σ υ )) is contained in the torsion part of the image of the natural homomorphism K n (Λ) → K n (Σ), where Λ is a maximal order in Σ. In particular, WK n (Σ) is finite. In the process, we prove that if Λ is a maximal order in a central division algebra D over F, then the kernel of the reduction map K 2n-1 (Λ) → π υ Π finiteυ K 2n-1 (d υ ) is finite. In paragraph 3 we investigate the connections between WK n (D) and div(K n (D)) and prove that divK 2 (Σ) is a subset of WK 2 (Σ); if the index of D is square free, then div(K 2 (D)) ≅ div(K 2 (F)), WK 2 (F) ≅ WK 2 (D) and vertical bar WK 2 (D)/div(K 2 (D)) vertical bar ≤ 2. Finally we prove that if D is a central division algebra over F with [D : F] = m 2 , then (1) div(K n (D)) l = WK n (D) l for all odd primes I and n ≤ 2; (2) if I does not divide m, then div(K 3 (D)) l = WK 3 (D) l = 0; (3) if F = Q and I does not divide m, then div(K n (D)) l is a subset of WK n (D) l for all n.

HIV diversity may be a useful biomarker for discriminating between recent and non-recent HIV infection. The high resolution melting (HRM) diversity assay was developed to quantify HIV diversity in viral populations without sequencing. In this assay, HIV diversity is expressed as a single numeric HRM score that represents the width of a melting peak. HRM scores are highly associated with diversity measures obtained with next generation sequencing. In this report, a software package, the HRM Diversity Assay Analysis Tool (DivMelt), was developed to automate calculation of HRM scores from melting curve data. DivMelt uses computational algorithms to calculate HRM scores by identifying the start (T1) and end (T2) melting temperatures for a DNA sample and subtracting them (T2 - T1 = HRM score). DivMelt contains many user-supplied analysis parameters to allow analyses to be tailored to different contexts. DivMelt analysis options were optimized to discriminate between recent and non-recent HIV infection and to maximize HRM score reproducibility. HRM scores calculated using DivMelt were compared to HRM scores obtained using a manual method that is based on visual inspection of DNA melting curves. HRM scores generated with DivMelt agreed with manually generated HRM scores obtained from the same DNA melting data. Optimal parameters for discriminating between recent and non-recent HIV infection were identified. DivMelt provided greater discrimination between recent and non-recent HIV infection than the manual method. DivMelt provides a rapid, accurate method of determining HRM scores from melting curve data, facilitating use of the HRM diversity assay for large-scale studies.

Don Juan Pond (DJP), Antarctica, is one of the most unusual surface waters on Earth because of its CaCl2-rich composition. To investigate the evolution of pond waters during closed-basin evaporation and to understand the source of brines responsible for the chemistry of DJP, we apply a newly developed low-temperature aqueous model in the Na-K-Ca-Mg-Cl system to DJP. By modeling the closed-basin evaporation of DJP and comparing ionic ratios between DJP surface water, deep groundwater, shallow groundwater, and other surface chemistries in Wright Valley, we find that DJP is best explained by upwelling deep groundwater, as opposed to recent hypotheses proposing shallow groundwater sources. The early closed-basin evolution of brines in our model accurately predicts observed chemistries in DJP; however, late-stage closed-basin evaporation produces Mg-K-rich brines and salts that do not match the CaCl2-rich brine in DJP. Based on groundwater inflow rates to DJP, we estimate that even the most concentrated brines in DJP have undergone closed-basin evaporation for less than a year. To explain the observed lack of Mg2+ and K+ accumulation in DJP over time, and the surprisingly young age for the brines, we deduce that DJP is a localized upwelling from a regional groundwater flow-through system in which evaporated DJP brines are recycled back into the subsurface over yearly timescales. The existence of a regional groundwater flow system beneath DJP has implications for water and solute budgets in cold desert ecosystems, and may provide clues for the formation of groundwater and aqueous flows on Mars.

FOXA1 is a transcription factor capable to bind silenced chromatin to direct context-dependent cell fate conversion. Here, we demonstrate that a compact palindromic DNA element (termed 'DIV' for its diverging half-sites) induces the homodimerization of FOXA1 with strongly positive cooperativity. Alternative structural models are consistent with either an indirect DNA-mediated cooperativity or a direct protein-protein interaction. The cooperative homodimer formation is strictly constrained by precise half-site spacing. Re-analysis of chromatin immunoprecipitation sequencing data indicates that the DIV is effectively targeted by FOXA1 in the context of chromatin. Reporter assays show that FOXA1-dependent transcriptional activity declines when homodimeric binding is disrupted. In response to phosphatidylinositol-3 kinase inhibition DIV sites pre-bound by FOXA1 such as at the PVT1/MYC locus exhibit a strong increase in accessibility suggesting a role of the DIV configuration in the chromatin closed-open dynamics. Moreover, several disease-associated single nucleotide polymorphisms map to DIV elements and show allelic differences in FOXA1 homodimerization, reporter gene expression and are annotated as quantitative trait loci. This includes the rs541455835 variant at the MAPT locus encoding the Tau protein associated with Parkinson's disease. Collectively, the DIV guides chromatin engagement and regulation by FOXA1 and its perturbation could be linked to disease etiologies.

Voltage-gated sodium channels are critical for the generation and propagation of electrical signals in most excitable cells. Activation of Na(+) channels initiates an action potential, and fast inactivation facilitates repolarization of the membrane by the outward K(+) current. Fast inactivation is also the main determinant of the refractory period between successive electrical impulses. Although the voltage sensor of domain IV (DIV) has been implicated in fast inactivation, it remains unclear whether the activation of DIV alone is sufficient for fast inactivation to occur. Here, we functionally neutralize each specific voltage sensor by mutating several critical arginines in the S4 segment to glutamines. We assess the individual role of each voltage-sensing domain in the voltage dependence and kinetics of fast inactivation upon its specific inhibition. We show that movement of the DIV voltage sensor is the rate-limiting step for both development and recovery from fast inactivation. Our data suggest that activation of the DIV voltage sensor alone is sufficient for fast inactivation to occur, and that activation of DIV before channel opening is the molecular mechanism for closed-state inactivation. We propose a kinetic model of sodium channel gating that can account for our major findings over a wide voltage range by postulating that DIV movement is both necessary and sufficient for fast inactivation.

Recovery from fast inactivation in voltage-dependent Na+ channels is associated with a slow component in the time course of gating charge during repolarization (i.e. charge immobilization), which results from the slow movement of the S4 segments in domains III and IV (S4-DIII and S4-DIV). Previous studies have shown that the non-specific removal of fast inactivation by the proteolytic enzyme pronase eliminated charge immobilization, while the specific removal of fast inactivation (by intracellular MTSET modification of a cysteine substituted for the phenylalanine in the IFM motif, ICMMTSET, in the inactivation particle formed by the linker between domains III and IV) only reduced the amount of charge immobilization by nearly one-half. To investigate the molecular origin of the remaining slow component of charge immobilization we studied the human cardiac Na+ channel (hH1a) in which the outermost arginine in the S4-DIV, which contributes approximately 20% to total gating charge (Qmax), was mutated to a cysteine (R1C-DIV). Gating charge could be fully restored in R1C-DIV by exposure to extracellular MTSEA, a positively charged methanethiosulphonate reagent. The RIC-DIV mutation was combined with ICMMTSET to remove fast inactivation, and the gating currents of R1C-DIV-ICM(MTSET) were recorded before and after modification with MTSEAo. Prior to MTSEAo, the time course of the gating charge during repolarization (off-charge) was best described by a single fast time constant. After MTSEA, the off-charge had both fast and slow components, with the slow component accounting for nearly 35% of Qmax. These results demonstrate that the slow movement of the S4-DIV during repolarization is not dependent upon the normal binding of the inactivation particle.

Carbohydrates, total calorie content and sensory characteristics of the formulated products were also considered. Adult sheep meat contained 19% of protein, 5.4% of lipids, 1.18% of ashes and 76% of humidity. The meat from adult sheep and that from young animals differed remarkably in terms of lipid content. All other parameters complied with current meat regulations, although the addition of oats and/or pork to the burgers modified the ash and humidity contents. The sensory evaluation revealed that the sample containing 50% of adult sheep meat, 46% of pork and 4% of oats – which represents the maximum content allowed by law for non-meat sources of protein – enjoyed more widespread acceptance.

Retinal tissue can receive incidental γ-rays exposure during radiotherapy either of tumors of the eye and optic nerve or of head-and-neck tumors, and during medical diagnostic procedures. Healthy retina is therefore at risk of suffering radiation-related side effects and the knowledge of pathophysiological response of retinal cells to ionizing radiations could be useful to design possible strategies of prevention and management of radiotoxicity. In this study, we have exploited an in vitro model (primary rat retinal cell culture) to study an array of biological effects induced on retinal neurons by γ-rays. Most of the different cell types present in retinal tissue - either of the neuronal or glial lineages - are preserved in primary rat retinal cultures. Similar to the retina in situ, neuronal cells undergo in vitro a maturational development shown by the formation of polarized neuritic trees and operating synapses. Since 2 Gy is the incidental dose received by the healthy retina per fraction when the standard treatment is delivered to the brain, retina cell cultures have been exposed to 1 or 2 Gy of γ-rays at different level of neuronal differentiation in vitro: days in vitro (DIV)2 or DIV8. At DIV9, retinal cultures were analyzed in terms of viability, apoptosis and characterized by immunocytochemistry to identify alterations in neuronal differentiation. After irradiation at DIV2, MTT assay revealed an evident loss of cell viability and βIII-tubulin immunostaining highlighted a marked neuritic damage, indicating that survived neurons showed an impaired differentiation. Differentiated cultures (DIV8) appeared to be more resistant with respect to undifferentiated, DIV2 cultures, both in terms of cell viability and differentiation. Apoptosis evaluated with TUNEL assay showed that irradiation at both DIV2 and DIV8 induced a significant increase in the apoptotic rate. To further investigate the effects of γ-rays on retinal neurons, we evaluated the

Recently, Burden and Tang (2016) provided an analytical expression for the stationary distribution of the multivariate neutral Wright-Fisher model with low mutation rates. In this paper we present a simple, alternative derivation that illustrates the approximation. Our proof is based on the discrete multivariate boundary mutation model which has three key ingredients. First, the decoupled Moran model is used to describe genetic drift. Second, low mutation rates are assumed by limiting mutations to monomorphic states. Third, the mutation rate matrix is separated into a time-reversible part and a flux part, as suggested by Burden and Tang (2016). An application of our result to data from several great apes reveals that the assumption of stationarity may be inadequate or that other evolutionary forces like selection or biased gene conversion are acting. Furthermore we find that the model with a reversible mutation rate matrix provides a reasonably good fit to the data compared to the one with a non-reversible mutation rate matrix.

In Victoria, maternity services are under significant strain due to increased numbers of women giving birth and critical workforce shortages. Hospitals have experienced challenges in adequately staffing maternity units, particularly on postnatal wards. In 2008, a tertiary maternity hospital in Melbourne introduced a model where undergraduate midwifery students were employed as Division 2 nurses (SMW_Div2) (enrolled nurses), to work in the postnatal area only. This study explored the pilot employment model from the perspective of the SMW_Div2 and hospital midwives. A web-based survey was administered to hospital midwives and the SMW_Div2s in the employment model in January 2010. The survey explored the views of midwives and SMW_Div2s regarding the perceived impact of the model on workforce readiness, recruitment and retention, and clinical competence and confidence. Forty-seven of 158 midwives (30%) and five of nine SMW_Div2s employed in the model responded to the survey. Both groups considered the model to have benefits for the organisation, including increased: student workforce readiness; clinical confidence and competence; and organisational loyalty. Both groups also considered that the model would facilitate: workforce recruitment; a teaching and learning culture within the organisation; and enhanced partnerships between students, hospitals and universities. Caution was expressed regarding workload and the need for ongoing support for SMW_Div2s working in the model. SMW_Div2s and midwives were positive about the introduction of the paid employment model at the Women's. The findings are consistent with evaluations of similar programs in the nursing setting. The employment model has potential short and long term individual and organisational advantages, which is important in the context of increasing births and workforce shortages. Progression of such models will be contingent on the collaboration and cooperation of the various stakeholders involved in maternity

div>The purpose of the present study is to determine the cultural and social barriers that are preventing Laredoans from accessing the digital world. This multigenerational study examines how three generations within 16 families relate culturally and socially to technology. Three members from the same family were invited to voluntarily participate in the study, with a total of 48 in-depth, face-to-face interviews being conducted. The present study identified several barriers such as low educational level, low income, lack of English language proficiency, lack of relevant content available in other languages besides English, preference to communicate face-to-face, fear of violence, and endless working hours. Laredo is the least connected city in the nation with 40.2% non-connectivity rate. Research is needed to understand this digital inequity situation in this borderland city. The theoretical framework used is rooted on Straubhaar’s concepts of techno-field, techno-disposition, and techno-capital.

Full Text Available <div>Na perspectiva de uma maior concretude do projeto ético-político do Serviço Social no Brasil, tem havido nos últimos anos uma forte aproximação entre as unidades de formação profissional e os movimentos sociais, dentre os quais se destaca o Movimento Nacional dos Trabalhadores Sem Terra – MST. Esse importante movimento tem desencadeado uma estratégia de formação de seus militantes e de outros movimentos sociais e, a partir disso, fundou a Escola Nacional Florestan Fernandes. Ali, os militantes tomam contato com um variado cardápio crítico de conteúdos que vão desde a teoria social, o entendimento do modo de produção capitalista, a formação social brasileira e suas particularidades, até discussões sobre o movimento e os processos de formação da consciência. Contudo, essa estratégia vem passando também pelo estreitamento de laços com as universidades públicas, por meio muitas vezes do Serviço Social, criando cursos de graduação para turmas especiais, como na UFRJ, formadas por militantes dos movimentos.

Full Text Available Diagnostic characteristics of acetoin production to the Staphylococcus aureus isolated from milk of mammary quarters of cows with mastitis, orifices of teats and mouthpieces of the liners were studied, in agreement to different coagulation grades presented by strains in the tube coagulase test with rabbit plasma and different rain levels in the environment of the herd. The production of acetoin and the coagulase test were performed after growth on blood agar base supplemented with sheep blood, Gram staining and catalase production. All strains were confirmed by molecular identification at species level by species-specific PCR. Among 329 samples identified, 167 were isolated from milk, 117 from teat orifices and 45 from mouthpieces of the liners. Among these samples, 85.0%, 71.1% and 69.2% strains originated from the milk, mouthpieces and orifices, respectively, presented whole coagulation in the coagulase test. Reduced specificities were obtained to the acetoin production to different coagulation grades on the few rains period as well as on the many rains period. Sensitivities to the acetoin production were higher on the few rains period to all sources and coagulation grades, except to strains from orifices with incomplete coagulation and strains from mouthpieces with complete coagulation. It is recommended the acetoin production test how a good diagnostic strategy to the S. aureus identification, combined with other tests how coagulase, mainly in the milk samples originated from mastitic mammary quarters and on periods with little occurrence of rains.<div>

Microglia change from a reactive to an age-like phenotype with the time in culture
Caldeira, Cláudia; Oliveira, Ana F.; Cunha, Carolina; Vaz, Ana R.; Falcão, Ana S.; Fernandes, Adelaide; Brites, Dora
2014-01-01
Age-related neurodegenerative diseases have been associated with chronic neuroinflammation and microglia activation. However, cumulative evidence supports that inflammation only occurs at an early stage once microglia change the endogenous characteristics with aging and switch to irresponsive/senescent and dystrophic phenotypes with disease progression. Thus, it will be important to have the means to assess the role of reactive and aged microglia when studying advanced brain neurodegeneration processes and age-associated related disorders. Yet, most studies are done with microglia from neonates since there are no adequate means to isolate degenerating microglia for experimentation. Indeed, only a few studies report microglia isolation from aged animals, using either short-term cultures or high concentrations of mitogens in the medium, which trigger microglia reactivity. The purpose of this study was to develop an experimental process to naturally age microglia after isolation from neonatal mice and to characterize the cultured cells at 2 days in vitro (DIV), 10 DIV, and 16 DIV. We found that 2 DIV (young) microglia had predominant amoeboid morphology and markers of stressed/reactive phenotype. In contrast, 16 DIV (aged) microglia evidenced ramified morphology and increased matrix metalloproteinase (MMP)-2 activation, as well as reduced MMP-9, glutamate release and nuclear factor kappa-B activation, in parallel with decreased expression of Toll-like receptor (TLR)-2 and TLR-4, capacity to migrate and phagocytose. These findings together with the reduced expression of microRNA (miR)-124, and miR-155, decreased autophagy, enhanced senescence associated beta-galactosidase activity and elevated miR-146a expression, are suggestive that 16 DIV cells mainly correspond to irresponsive/senescent microglia. Data indicate that the model represent an opportunity to understand and control microglial aging, as well as to explore strategies to recover microglia surveillance

Spatial mapping of mineralization with manganese-enhanced magnetic resonance imaging
Chesnick, I.E.; Centeno, J.A.; Todorov, T.I.; Koenig, A.E.; Potter, K.
2011-01-01
Paramagnetic manganese can be employed as a calcium surrogate to sensitize the magnetic resonance imaging (MRI) technique to the processing of calcium during the bone formation process. At low doses, after just 48h of exposure, osteoblasts take up sufficient quantities of manganese to cause marked reductions in the water proton T1 values compared with untreated cells. After just 24h of exposure, 25??M MnCl2 had no significant effect on cell viability. However, for mineralization studies 100??M MnCl2 was used to avoid issues of manganese depletion in calvarial organ cultures and a post-treatment delay of 48h was implemented to ensure that manganese ions taken up by osteoblasts is deposited as mineral. All specimens were identified by their days in vitro (DIV). Using inductively coupled plasma optical emission spectroscopy (ICP-OES), we confirmed that Mn-treated calvariae continued to deposit mineral in culture and that the mineral composition was similar to that of age-matched controls. Notably there was a significant decrease in the manganese content of DIV18 compared with DIV11 specimens, possibly relating to less manganese sequestration as a result of mineral maturation. More importantly, quantitative T1 maps of Mn-treated calvariae showed localized reductions in T1 values over the calvarial surface, indicative of local variations in the surface manganese content. This result was verified with laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS). We also found that ??R1 values, calculated by subtracting the relaxation rate of Mn-treated specimens from the relaxation rate of age-matched controls, were proportional to the surface manganese content and thus mineralizing activity. From this analysis, we established that mineralization of DIV4 and DIV11 specimens occurred in all tissue zones, but was reduced for DIV18 specimens because of mineral maturation with less manganese sequestration. In DIV25 specimens, active mineralization was observed for

Self-organized criticality in developing neuronal networks.
Directory of Open Access Journals (Sweden)
Christian Tetzlaff
Full Text Available Recently evidence has accumulated that many neural networks exhibit self-organized criticality. In this state, activity is similar across temporal scales and this is beneficial with respect to information flow. If subcritical, activity can die out, if supercritical epileptiform patterns may occur. Little is known about how developing networks will reach and stabilize criticality. Here we monitor the development between 13 and 95 days in vitro (DIV of cortical cell cultures (n = 20 and find four different phases, related to their morphological maturation: An initial low-activity state (≈19 DIV is followed by a supercritical (≈20 DIV and then a subcritical one (≈36 DIV until the network finally reaches stable criticality (≈58 DIV. Using network modeling and mathematical analysis we describe the dynamics of the emergent connectivity in such developing systems. Based on physiological observations, the synaptic development in the model is determined by the drive of the neurons to adjust their connectivity for reaching on average firing rate homeostasis. We predict a specific time course for the maturation of inhibition, with strong onset and delayed pruning, and that total synaptic connectivity should be strongly linked to the relative levels of excitation and inhibition. These results demonstrate that the interplay between activity and connectivity guides developing networks into criticality suggesting that this may be a generic and stable state of many networks in vivo and in vitro.

Highlights: • The transient thermal behaviour of external multilayer walls of buildings is studied. • Reference results for four representative walls, obtained with a numerical model, are provided. • Shortcomings of approaches based on the Mackey-and-Wright method are identified. • Handling full-feature excitations with Fourier series decomposition improves accuracy. • A simpler, yet accurate, promising novel approach to predict heat gain is proposed. - Abstract: Nowadays, simulation tools are available for calculating the thermal loads of multiple rooms of buildings, for given inputs. However, due to inaccuracies or uncertainties in some of the input data (e.g., thermal properties, air infiltrations flow rates, building occupancy), the evaluated thermal load may represent no more than just an estimate of the actual thermal load of the spaces. Accordingly, in certain practical situations, simplified methods may offer a more reasonable trade-off between effort and results accuracy than advanced software. Hence, despite the advances in computing power over the last decades, simplified methods for the evaluation of thermal loads are still of great interest nowadays, for both the practicing engineer and the graduating student, since these can be readily implemented or developed in common computational-tools, like a spreadsheet. The method of Mackey and Wright (M&W) is a simplified method that upon values of the decrement factor and time lag of a wall (or roof) estimates the instantaneous rate of heat transfer through its indoor surface. It assumes cyclic behaviour and shows good accuracy when the excitation and response have matching shapes, but it involves non negligible error otherwise, for example, in the case of walls of high thermal inertia. The aim of this study is to develop a simplified procedure that considerably improves the accuracy of the M&W method, particularly for excitations that noticeably depart from the sinusoidal shape, while not

A simple, reliable and sensitive high-performance liquid chromatography tandem mass spectrometry method (HPLC-MS/MS) was established for simultaneous analyses of the following 5 steroid saponins in rat plasma after the single dose administration of total steroid saponins extracted from the rhizome of Dioscorea zingiberensis C.H.Wright for the first time. Protodioscin, huangjiangsu A, zingiberensis new saponin, dioscin, and gracillin were quantified using ginsenoside Rb1 as the internal standard (IS). The plasma samples were pretreated by a single step acetonitrile-mediated protein precipitation. The chromatographic separation was performed on an Inersil ODS-3 C18 column (250 mm × 4.6 mm, 5 μm) with the mobile phase composed of acetonitrile and water containing 0.1% formic acid under a gradient elution mode at 0.2 mL min−1 using a microsplit after the eluent from the HPLC apparatus. The quantification was accomplished on a triple quadrupole tandem mass spectrometer using the multiple reaction monitoring (MRM) in the positive ionization mode. The above five analytes were stable under sample storage and preparation conditions applied in the present study. The linearity, precision, accuracy, and recoveries of the analysis confirmed the requirements for quality-control purposes. After validation, this proposed method was successfully adopted to investigate the pharmacokinetic parameters of these five analytes. PMID:25201262

2016-01-01
User interfaces are important to facilitate easy learning and operating with an IT application especially in the medical world. An easy to use interface has to be simple and to customize the user needs and mode of operation. The technology in the background is an important tool to accomplish this. The present work aims to creating a web interface using specific technology (HTML table design combined with CSS3) to provide an optimized responsive interface for a complex web application. In the first phase, the current icMED web medical application layout is analyzed, and its structure is designed using specific tools, on source files. In the second phase, a new graphic adaptable interface to different mobile terminals is proposed, (using HTML table design (TD) and CSS3 method) that uses no source files, just lines of code for layout design, improving the interaction in terms of speed and simplicity. For a complex medical software application a new prototype layout was designed and developed using HTML tables. The method uses a CSS code with only CSS classes applied to one or multiple HTML table elements, instead of CSS styles that can be applied to just one DIV tag at once. The technique has the advantage of a simplified CSS code, and a better adaptability to different media resolutions compared to DIV-CSS style method. The presented work is a proof that adaptive web interfaces can be developed just using and combining different types of design methods and technologies, using HTML table design, resulting in a simpler to learn and use interface, suitable for healthcare services.

The low temperature boundary layer plasma (scrape-off layer or SOL) between the hot core and the surrounding vessel determines the level of power loading, erosion and implantation of material surfaces, and thus the viability of tokamak-based fusion as an energy source. This study explores mechanisms affecting the formation of flattened density profiles, so-called ‘density shoulders’, in the low-field side (LFS) SOL, which modify ion and neutral fluxes to surfaces—and subsequent erosion. We find that increases in SOL parallel resistivity, Λdiv (=[L || ν eiΩi]/c sΩe), postulated to lead to shoulder growth through changes in SOL turbulence characteristics, correlates with increases in SOL shoulder amplitude, A s, only under a subset of conditions (D2-fuelled L-mode density scans with outer strike point on the horizontal target). Λdiv fails to correlate with A s for cases of N2 seeding or during sweeping of the strike point across the horizontal target. The limited correlation of Λdiv and A s is also found for H-mode discharges. Thus, while it may be necessary for Λdiv to be above a threshold of ~1 for shoulder formation and/or growth, another mechanism is required. More significantly, we find that in contrast to parallel resistivity, outer divertor recycling, as quantified by the total outer divertor Balmer D α emission, I-D α , does scale with A s where Λdiv does and even where Λdiv does not. Divertor recycling could lead to SOL density shoulder formation through: (a) reducing the parallel to the field flow (loss) of ions out of the SOL to the divertor; and (b) changes in radial electric fields which lead to E × B poloidal flows as well as potentially affecting SOL turbulence birth characteristics. Thus, changes in divertor recycling may be the sole process involved in bringing about SOL density shoulders or it may be that it acts in tandem with parallel resistivity.

HIV/sexually transmitted infections (STIs) and drug abuse remain significant public health concerns in the United States, and African American and Hispanic youth are disproportionately affected. Although technology-based interventions are efficacious in preventing and reducing HIV/STI and licit/illicit drug use behaviors, relatively little is known regarding the state of the science of these interventions among African American and Hispanic youth. The aim of this review is to identify and examine randomized controlled trials (RCTs) of technology-based HIV/STI and/or drug abuse preventive interventions for African American and Hispanic youth. We searched electronic databases (ie, PubMed, Proquest, PsycINFO, Ebscohost, Google Scholar) to identify studies between January 2006 and October 2016. RCTs of technology-based interventions targeting African American and Hispanic youth HIV/STI risk behaviors, including sexual risk, licit and illicit drug use, and HIV/STI testing were included. Our search revealed a total of three studies that used an RCT design and included samples comprised of >50% African American and/or Hispanic youth. The follow-up assessments ranged from two weeks to six months and the number of participants in each trial ranged from 72 to 141. The three interventions were theory-driven, interactive, and tailored. The long-term effects of the interventions were mixed, and outcomes included reductions in sex partners, licit drug use, and condomless anal sex acts. Although technology-based interventions seem promising in the prevention of HIV/STI and drug abuse among African American and Hispanic youth, more research is needed. ©David Córdova, Frania Mendoza Lua, Lauretta Ovadje, Ethan Hong, Berenice Castillo, Christopher P Salas-Wright.

The dynamic changes of muscarinic receptor density and its reactivity during aging process in primary cultured neutrons were studied. Muscarinic receptor density was measured by 3 H-QNB binding assay, and muscarinic receptor reactivity was assessed by carbachol stimulation of cGMP formation, the latter was measured by RIA. After 2 weeks' incubation of neonatal rat brain cells, the nutrients began to rupture and the cell bodies shrank markedly showing senescent feature. The muscarinic receptor density reached peak at the 12th day in vitro (12 DIV), but the muscarinic receptor reactivity reached peak at 9 DIV and declined significantly at 12 DIV. The results demonstrated that during aging process of primary cultured neutrons, the decline of muscarinic receptor reactivity is likely prior to the decrease of receptor density

Electrodynamic Tethers and E-Sails as Active Experiment Testbeds and Technologies in Space
Gilchrist, B. E.; Wiegmann, B.; Johnson, L.; Bilen, S. G.; Habash Krause, L.; Miars, G.; Leon, O.
2017-12-01
The use of small-to-large flexible structures in space such as tethers continues to be studied for scientific and technology applications. Here we will consider tether electrodynamic and electrostatic interactions with magneto-plasmas in ionospheres, magnetospheres, and interplanetary space. These systems are enabling fundamental studies of basic plasma physics phenomena, allowing direct studies of the space environment, and generating technological applications beneficial for science missions. Electrodynamic tethers can drive current through the tether based on the Lorenz force adding or extracting energy from its orbit allowing for the study of charged bodies or plasma plumes moving through meso-sonic magnetoplasmas [1]. Technologically, this also generates propulsive forces requiring no propellant and little or no consumables in any planetary system with a magnetic field and ionosphere, e.g., Jupiter [2]. Further, so called electric sails (E-sails) are being studied to provide thrust through momentum exchange with the hypersonic solar wind. The E-sail uses multiple, very long (10s of km) charged, mostly bare rotating conducting tethers to deflect solar wind protons. It is estimated that a spacecraft could achieve a velocity over 100 km/s with time [3,4]. 1. Banks, P.M., "Review of electrodynamic tethers for space plasma science," J.

Hypervelocity technology carbon/carbon testing
Anselmo, John V.; Kretz, Lawrence O.
The paper describes the procedures used at the Structures Test Laboratory of the Wright Laboratory's Flight Dynamics Directorate to test a carbon/carbon hot structure representing a typical hypersonic gliding body, and presents the results of tests. The forebody was heated to 1371 C over 13 test runs, using radiant quartz lamps; a vertical shear force of 5.34 kN was introduced to the nose at a stabilized temperature of 816 C. Test data were collected using prototype high-temperature strain gages, in-house-designed high-temperature extensometers, conventional strain gages, and thermocouples. Video footage was taken of all test runs. Test runs were successfully completed up to 1371 C with flight typical thermal gradients at heating rates up to 5.56 C/sec. Results showed that, overall, the termal test control systems performed as predicted and that test temperatures and thermal gradients were achieved to within about 5 percent in most cases.

Estimation of immunological and microbiological diversity is vital to our understanding of infection and the immune response. For instance, what is the diversity of the T cell repertoire? These questions are partially addressed by high-throughput sequencing techniques that enable identification of immunological and microbiological “species” in a sample. Estimators of the number of unseen species are needed to estimate population diversity from sample diversity. Here we test five widely used non-parametric estimators, and develop and validate a novel method, DivE, to estimate species richness and distribution. We used three independent datasets: (i) viral populations from subjects infected with human T-lymphotropic virus type 1; (ii) T cell antigen receptor clonotype repertoires; and (iii) microbial data from infant faecal samples. When applied to datasets with rarefaction curves that did not plateau, existing estimators systematically increased with sample size. In contrast, DivE consistently and accurately estimated diversity for all datasets. We identify conditions that limit the application of DivE. We also show that DivE can be used to accurately estimate the underlying population frequency distribution. We have developed a novel method that is significantly more accurate than commonly used biodiversity estimators in microbiological and immunological populations. PMID:24945836

In the chapters which follow each of the four Divisions, (Cosmic Ray Div., Space Plasma Div., Astronomy Div., and High Energy Astrophysic Div.) has described its work in the sequence: 'Support given to projects', 'Support given to studies', and 'Research activities'. The effort and time devoted to each area of work is by no means proportional to the length of text appearing in each area. Any attempt to fully describe support given to a project tends to result in what is merely a diary of meetings, tests, failures, re-scheduling efforts, repair of experiments, re-tests, compromise negotiation, inter-experimenter refereeing etc., and such diaries, although instructive, seemed inappropriate in this report. Reports on projects and studies therefore in general simply describe the project and say that it was supported. It should be mentioned, however, that major efforts, outside the normal role of SSD, have gone into the IUE and Exosat projects. The scientific operations of IUE were planned and are directed from the Astronomy Division to which the visiting scientists at Villafranca report. The design and production of the Exosat payload is being managed from the High Energy Astrophysics Division and plans are now being made for the operation of the Exosat Observatory and the distribution of the data

Full Text Available <div>Seasonal high temperatures or inadequate nutrition can decrease reproductive efficiency in boars, especially through a reduction in spermatozoal number / ejaculate and percentage of normal spermatozoa. The aim of this study was to evaluate the effect of organic and inorganic trace mineral supplementation on seminal quality in boars exposed to high environmental temperatures. The experiment was conducted in Southern Brazil, west of Parana State. Boars (2 years of age were divided into three groups to receive: inorganic (GIn, n=4 and organic (GOr, n=4 mineral supplementation and a lactation diet (GCo, n=5. Inorganic and organic diets contained a premix of inorganic and organic trace minerals, respectively, with the same quantity of each trace mineral, based on NRC (NRC, 1998 for boars. The lactation diet was based on NRC for lactating sows and contained a higher level of inorganic trace minerals, protein and metabolic energy. Maximum mean environmental temperatures were higher than the normal thermal comfort temperature for boars (26oC during the experimental period, and were associated with a reduction in semen quality. Results are expressed as mean ± SEM. The semen volume of Inorganic and Organic diet groups were higher than Lactation group animals (345.7 ± 92.6 mL and 338.4 ± 67.8 mL versus 302.5 ± 81.4 mL, respectively; P=0.02. Boars in the Organic diet group had higher sperm concentration when compared to the Inorganic diet group (233.5 ± 76.7 X 106 sptz/mL versus 181.2 ± 77.3 X 106 sptz/mL, respectively; P=0.006. Percentage of normal spermatozoa, averaged higher in the Organic group than both Inorganic and Lactation groups (93.31 ± 5.20% versus 78.48 ± 12.15% and 82.59 ± 17.27%, respectively; P=0.00021.

Full Text Available In this paper I examine Crispin Wright's modal anti-realism as based on the availability of a certain attitude of Caution towards judgements of necessity. I think that Wright's account should be attractive in several ways for modal theorists with an anti-realist bend. However, the attitude of Caution to which it appeals has attracted some controversy. Wright himself has later come to doubt whether Caution is ultimately coherent. Here I first address Wright's worries concerning the coherence of Caution and show that they are unfounded. But then I argue that although the attitude of Caution is coherent, it cannot provide a suitable basis for a non-eliminativist account of necessity. I offer two different objections against Caution. (1 I argue that Wright's appeal to Caution, if successful, would show not only that modal judgement is non-objective but also that it is dispensable. Thus, I claim that appeal to Caution would seem to serve more as a threat against a non-eliminativist account of necessity, rather than as a potential adequate basis for it. However, (2 I argue that Wright's appeal to Caution is unsuccessful, for there is no genuine Caution: Caution is a mere verbal attitude.

Modeling and control of active twist aircraft
Cramer, Nicholas Bryan
The Wright Brothers marked the beginning of powered flight in 1903 using an active twist mechanism as their means of controlling roll. As time passed due to advances in other technologies that transformed aviation the active twist mechanism was no longer used. With the recent advances in material science and manufacturability, the possibility of the practical use of active twist technologies has emerged. In this dissertation, the advantages and disadvantages of active twist techniques are investigated through the development of an aeroelastic modeling method intended for informing the designs of such technologies and wind tunnel testing to confirm the capabilities of the active twist technologies and validate the model. Control principles for the enabling structural technologies are also proposed while the potential gains of dynamic, active twist are analyzed.

Cell count was performed through a 0.01 mm2 section reticule and morphometric analysis with a stereological grid. The number of double immunoreactive cells peaked by 2 DIV to achieve its lowest value at 60 DIV. At 24 hs of cell seeding of successive passages, such values peaked by the 6th subculture to gradually decrease thereafter. Increasing cell hypertrophy was found during the long-term first subculture but not after passaging. At the end of the observation period, doubly immunolabeled astrocytes were still recorded, thus evidencing retention of proliferative potential despite aging.El grado de diferenciación celular y la actividad mitótica fueron secuencialmente determinados mediante marcación por inmunoperoxidasa de la proteína gliofibrilar ácida (GFAP y del antígeno nuclear de proliferación celular (PCNA, respectivamente, en cultivos astrocitarios obtenidos de encéfalo de rata y mantenidos hasta 60 días in vitro (DIV de su primer subcultivo, o mediante pasajes semanales hasta el 12do subcultivo.

Background Mycobacterium ulcerans, the causative agent of Buruli ulcer in humans, is unique among the members of Mycobacterium genus due to the presence of the virulence determinant megaplasmid pMUM001. This plasmid encodes multiple virulence-associated genes, including mup011, which is an uncharacterized Ser/Thr protein kinase (STPK) PknQ. Methodology/Principal Findings In this study, we have characterized PknQ and explored its interaction with MupFHA (Mup018c), a FHA domain containing protein also encoded by pMUM001. MupFHA was found to interact with PknQ and suppress its autophosphorylation. Subsequent protein-protein docking and molecular dynamic simulation analyses showed that this interaction involves the FHA domain of MupFHA and PknQ activation loop residues Ser170 and Thr174. FHA domains are known to recognize phosphothreonine residues, and therefore, MupFHA may be acting as one of the few unusual FHA-domain having overlapping specificity. Additionally, we elucidated the PknQ-dependent regulation of MupDivIVA (Mup012c), which is a DivIVA domain containing protein encoded by pMUM001. MupDivIVA interacts with MupFHA and this interaction may also involve phospho-threonine/serine residues of MupDivIVA. Conclusions/Significance Together, these results describe novel signaling mechanisms in M. ulcerans and show a three-way regulation of PknQ, MupFHA, and MupDivIVA. FHA domains have been considered to be only pThr specific and our results indicate a novel mechanism of pSer as well as pThr interaction exhibited by MupFHA. These results signify the need of further re-evaluating the FHA domain –pThr/pSer interaction model. MupFHA may serve as the ideal candidate for structural studies on this unique class of modular enzymes. PMID:25412098

In the last decades researchers started taking into account traditional and marginal food products by an accurate scientific approach aiming to their exploitation and to define their quality and safety parameters. Scientific approach to marginal products can be schematically divided in two levels: analytical and technological/engineering. In general, the analytical approach focuses on chemical aspects, physical properties, aromatic and sensorial characteristics and on the microbiological and genetic characterizations. <div>The technological/engineering approach must be considered a san integration of the knowledge both about the finished product and the production process and consists of: the definition of markers connecting quality to first matter; the study of seasonal and annual variability; the search for correlations among process/environment/quality on molecular basis; the pointing out of markers to set traceability systems up; the definition of key-factors to characterize the land according to its food production as an impulse for the development of other sectors such as tourism. Finally, innovation in the sector of traditional and marginal production should concern the definition of chemicalphysical and sensorial characteristics, the rationalization of traditional processes and the introduction of new compatible technology phases, the introduction of new packaging forms to elongate the shelf life and to enlarge distribution areas guaranteeing, at the same time, the maintenance of product peculiarity and typicality. New food design is one of the most

1981-08-01
LMFBR fuel elements consist of wire-wrapped rod bundles, with triangular array, with the fluid flowing parallel to the rods. A semi-empirical model is developed in order to obtain the average bundle friction factor, as well as the friction factor for each subchannel. The model also calculates the flow distribution factors. The results are compared to experimental data for geometrical parameters in the range: P(div)D = 1.063 - 1.417, H(div)D = 4 - 50, and are considered satisfactory. (Author) [pt

While the domain of security dependent technologies brings new challenges to HCI research it seems that the results and breakthroughs of HCI have not been used in design of security dependent technologies. With exceptions, work in the research field of usable security may be criticized for focusing...... mainly on adjusting user behavior to behave securely. With our background in newer HCI perspectives we address secure interaction from the perspective of security technology as experience. We analyze a number of collected user stories to understand what happens when everyday users encounter security...... dependent technologies. We apply McCarthy & Wright's [12] experience framework to the security domain and our collected stories. We point out that there are significant differences between being secure and having a secure experience, and conclude that classical usable security, focus on people's immediate...

The objective of this report is, while giving explicit explanations of key variables of the scenarios, to propose a clear and pedagogic analysis of public political measures and of their impact, as well as envisaged technologies for the four trajectories of energy transition defined within the frame of the French National Debate on Energy Transition (DBTE). After a presentation of these four trajectories (DEC for high demand and electricity-based de-carbonation, DIV for average demand and vector diversity, EFF for energy efficiency and vector diversification, and SOB for energy saving and phasing out nuclear), and a presentation of the analysis methodology, a chapter analyses the underlying differences between these scenarios in terms of innovation and standard of living, of final energy consumption, of geography, of development of heat pumps, and of air and sea transport. Technical corrections applied to scenarios are also described. Then, the report proposes a comparative analysis of the evolution of energy demand per sector (housing, office building, transports, industry, agriculture) according to the four different scenarios, a comparative analysis of the evolution of energy production per vector (electricity, gas networks, heat networks, biomass) with an assessment in terms of primary energy, a discussion of issues related to research, innovation and development of technologies, and a discussion of the evolution of consumptions of fossil energies and renewable energies, of the share of renewable energies in final consumption, and of the level of greenhouse gas emissions. The last part discusses some lessons learned from this comparative analysis. Other interesting scenarios (Negatep, Ancre Div, Ademe, Negawatt) are presented in appendix, as well as some graphical representations of the developed analysis

Blackbellied angler (Lophius budegassa) and angler (L. piscatorius) are two important commercial species in the Bay of Biscay and the European fisheries infected by the microsporidian parasite Spraguea lophii. Samplings of both anglerfish were performed from a nine year time-series (2006-2014) from commercial fleet and bottom research surveys operating in southern Bay of Biscay and Galician waters (ICES Div. VIIIc and IXa2), Celtic Sea (Div. VIIh), south-western Ireland (Div. VIIj and VIIk), western Ireland and Porcupine Bank (Div. VIIb and VIIc). Length and sex of fish and presence or absence of the parasite were recorded. The prevalence by Spraguea was used to analyse the infection level. The role of each variable (fish length, fish sex, geographical area and year) and the interactions among them on the Spraguea prevalence were analyzed by using a binomial GLM. Area and fish length had a more relevant effect on the infestation of both anglerfish, while the impact of the year and fish sex was less evident. The Spraguea prevalence by area ranged between 11% and 52% in L. budegassa and between 39% and 66% in L. piscatorius. This is the first study in which the prevalence of this parasite in L. budegassa is analyzed in several areas and inter-annually compared. A non-linear relationship with a sharp increment of the prevalence with fish length was obtained in both anglerfish. The results were compared with those from the scarce previous studies and discussed.

There is considerable genetic and phenotypic heterogeneity associated with intellectual disability (ID), specific learning disabilities, attention-deficit hyperactivity disorder, autism and epilepsy. The intelligence quotient (IQ) motif and SEC7 domain containing protein 2 gene (IQSEC2) is located on the X-chromosome and harbors mutations that contribute to non-syndromic ID with and without early-onset seizure phenotypes in both sexes. Although IQ and Sec7 domain mutations lead to partial loss of IQSEC2 enzymatic activity, the in vivo pathogenesis resulting from these mutations is not known. Here we reveal that IQSEC2 has a key role in dendritic spine morphology. Partial loss-of-function mutations were modeled using a lentiviral short hairpin RNA (shRNA) approach, which achieved a 57% knockdown of Iqsec2 expression in primary hippocampal cell cultures from mice. Investigating gross morphological parameters after 8 days of in vitro culture (8DIV) identified a 32% reduction in primary axon length, in contrast to a 27% and 31% increase in the number and complexity of dendrites protruding from the cell body, respectively. This increase in dendritic complexity and spread was carried through dendritic spine development, with a 34% increase in the number of protrusions per dendritic segment compared with controls at 15DIV. Although the number of dendritic spines had normalized by 21DIV, a reduction was noted in the number of immature spines. In contrast, when modeling increased dosage, overexpression of wild-type IQSEC2 led to neurons with shorter axons that were more compact and displayed simpler dendritic branching. Disturbances to dendritic morphology due to knockdown of Iqsec2 were recapitulated in neurons from Iqsec2 knockout mice generated in our laboratory using CRISPR/Cas9 technology. These observations provide evidence of dosage sensitivity for IQSEC2, which normally escapes X-inactivation in females, and links these disturbances in expression to alterations in

Purpose: The passive scattering proton therapy (PSPT) technique is the commonly used radiotherapy technique for craniospinal irradiation (CSI). However, PSPT involves many numbers of junction shifts applied over the course of treatment to reduce the cold and hot regions caused by field mismatching. In this work, we introduced a robust planning approach to develop an optimal and clinical efficient techniques for CSI using intensity modulated proton therapy (IMPT) so that junction shifts can essentially be eliminated. Methods: The intra-fractional uncertainty, in which two overlapping fields shift in the opposite directions along the craniospinal axis, are incorporated into the robust optimization algorithm. Treatment plans with junction sizes 3,5,10,15,20,25 cm were designed and compared with the plan designed using the non-robust optimization. Robustness of the plans were evaluated based on dose profiles along the craniospinal axis for the plans applying 3 mm intra-fractional shift. The dose intra-fraction variations (DIV) at the junction are used to evaluate the robustness of the plans. Results: The DIVs are 7.9%, 6.3%, 5.0%, 3.8%, 2.8% and 2.2%, for the robustly optimized plans with junction sizes 3,5,10,15,20,25 cm. The DIV are 10% for the non-robustly optimized plans with junction size 25 cm. The dose profiles along the craniospinal axis exhibit gradual and tapered dose distribution. Using DIVs less than 5% as maximum acceptable intrafractional variation, the overlapping region can be reduced to 10 cm, leading to potential reduced number of the fields. The DIVs are less than 5% for 5 mm intra-fractional shifts with junction size 25 cm, leading to potential no-junction-shift for CSI using IMPT. Conclusion: This work is the first report of the robust optimization on CSI based on IMPT. We demonstrate that robust optimization can lead to much efficient carniospinal irradiation by eliminating the junction shifts

The X-ray Spectrum Produced by 322 Mev Electrons Striking a Platinum Target. The differential energy spectrum of the photons produced by 322 Mev electrons striking a 20 mil platinum target was measured by observing the energy of 3467 pairs produced in a one mil thick lead foil in a Wilson cloud chamber in a magnetic field of 10,000 gauss. The spectrum is found to agree with that predicted by the Bethe-Heitler bremsstrahlung theory using a Thomas-Fermi model with suitable corrections for the thickness of the target. The energy of the 322 Mev electrons was determined by the spectrum of the photons observed in this experiment. Apparatus used and the experimental data and results obtained are reported fully in UCRL-660.

Divided versus selective attention: evidence for common processing mechanisms.

2008-06-18
The current study revisited the question of whether there are brain mechanisms specific to divided attention that differ from those used in selective attention. Increased neuronal activity required to simultaneously process two stimulus dimensions as compared with each separate dimension has often been observed, but rarely has activity induced by a divided attention condition exceeded the sum of activity induced by the component tasks. Healthy participants performed a selective-divided attention paradigm while undergoing functional Magnetic Resonance Imaging (fMRI). The task required participants to make a same-different judgment about either one of two simultaneously presented stimulus dimensions, or about both dimensions. Performance accuracy was equated between tasks by dynamically adjusting the stimulus display time. Blood Oxygenation Level Dependent (BOLD) signal differences between tasks were identified by whole-brain voxel-wise comparisons and by region-specific analyses of all areas modulated by the divided attention task (DIV). No region displayed greater activation or deactivation by DIV than the sum of signal change by the two selective attention tasks. Instead, regional activity followed the tasks' processing demands as reflected by reaction time. Only a left cerebellar region displayed a correlation between participants' BOLD signal intensity and reaction time that was selective for DIV. The correlation was positive, reflecting slower responding with greater activation. Overall, the findings do not support the existence of functional brain activity specific to DIV. Increased activity appears to reflect additional processing demands by introducing a secondary task, but those demands do not appear to qualitatively differ from processes of selective attention.

Realizing the Dream of Flight: Biographical Essays in Honor of the Centennial of Flight, 1903-2003
Dawson, Virginia P. (Editor); Bowles, Mark D. (Editor)
2005-01-01
While growing up in Cedar Rapids, Iowa, Milton Wright, The Wright Brothers Father, liked to purchase toys for his sons that he hoped would stimulate their imagination. One of the most memorable gifts was a toy helicopter that was designed by the French aeronautical experimenter Alphonse P naud. Milton gave his sons this gift in 1878, and, though it was a simple device with a stick bound to a four-blade rotor set in a spindle, it had the intended effect it caused them to dream. Twenty-five years separated the gift of this toy and their invention of the airplane, yet the Wright brothers were convinced it had exerted an important influence. Tom Crouch argued in The Bishop's Boys that toys like these perfectly illustrated the significance of play for technological innovation. He wrote, rotary-wing toys were to intrigue and inspire generations of children, a few of whom would, as adults, attempt to realize the dream of flight for themselves. If the first powered flight on 17 December 1903 represented a childhood dream realized, it was only the first step in the rapid evolution of the airplane from their flimsy kite-like contraption of wood and cloth to jet airliners and rockets in space. And, as extraordinary as the achievement of powered flight seemed in 1903, before the end of the century, space travel also would become a dream realized. Soviet astronaut Yuri Gagarin first circumnavigated Earth in April 1961, and, eight years later, American astronauts took the first steps for humankind on the Moon. It is with great pleasure that we introduce Realizing the Dream: Biographical Essays in Honor of the Centennial of Flight. These essays in celebration of the Wright brothers first flight 100 years ago grew out of presentations by a group of prominent scholars in 2003 at a conference sponsored by the NASA History Division and held at the Great Lakes Science Center in Cleveland, Ohio. The volume focuses on the careers of some of the many men and women who helped to realize

Making School Development Credible. Text, Context, Irony
Directory of Open Access Journals (Sweden)
Mats Börjesson
2012-01-01
Full Text Available
The article argues for the importance of an open, reflexive-methodological approach when switching between studying text, context and researcher activity. Close linguistic analysis can benefit from being linked with the researcher’s contextualisation of his empirical material as well as with more distanced readings. The more specific starting point for this article is that school development, like other similar terms such as school improvement and the like, makes use of linguistic building blocks with which whole narratives about today’s and tomorrow’s schools can be constructed. The subject of the study is a short text issued by the Swedish Schools Inspectorate (Skolinspektionen. Government language changes according to the authorities’ role in society and their own definitions of their functions, and an important aspect here is the legitimacy of the authorities’ texts. By means of various kinds of close linguistic analysis, the above-mentioned text is studied with regard to choice of categories, hierarchies of modalisation and the rhetorical effects of different types of formulations in a broader political-social landscape. The article concludes with a reflective discussion on the relationship between government language and irony as a stylistic device – a device that is based on the results of the close empirical analysis.[i]

Chronic vulvovaginitis in women older than 50 years: analysis of a prospective database.
Nyirjesy, Paul; Leigh, Randi D; Mathew, Leny; Lev-Sagie, Ahinoam; Culhane, Jennifer F
2012-01-01
This study aimed to examine differences in symptoms and diagnoses between women 50 years and younger and women older than 50 years who have chronic vulvovaginal complaints. New patients of the Drexel University Vaginitis Center with chronic vulvovaginal complaints were eligible. Participants underwent a standardized medical evaluation and completed detailed questionnaires. Data were analyzed using the t test, χ test, and the Fisher exact test. Subjects were 469 women aged 18 to 79 years. Subjects 50 years and younger (group A) were more likely to complain of vaginal itching and were less likely to complain of burning, irritation, or soreness (p ≤ .05 for all). Subjects older than 50 years (group B) were more likely to be diagnosed with atrophic vaginitis (p = .000), desquamative inflammatory vaginitis (DIV; p = .001), lichen planus (LP; p = .000), and lichen sclerosus (p = .000). Diagnosis of LS, LP, or DIV was associated with increased likelihood of multiparity and decreased likelihood of a history of systemic estrogen use. Postmenopausal women are more likely than premenopausal women to be diagnosed with DIV, LP, or LS. Both childbirth and estrogen nonuse were associated with the occurrence of these latter 3 conditions.

The production facilities, design and manufacturing technologies, and quality assurance in the Toyo Works, Ehime Manufactory, Sumitomo Heavy Industries, Ltd., which manufactures pressure vessels, are described, and especially the actual example of non-destructive tests is shown. The Toyo Works was completed in April, 1973, to manufacture large structures such as pressure vessels, offshore structures and bridges. The total area of the site is 535,000 m 2 , that of factory buildings is 33,600 m 2 , and the outdoor assembling yard is 114,800 m 2 . The large dry dock and main installations such as 12,000 tf hydraulic press, an annealing furnace, a heat treating furnace, a quenching tank, a horizontal boring machine, 6 m vertical lathe, various welding machines, 8 MeV X-ray apparatus, sand blasting and pickling facilities, and two 160 t cranes for shipment are arranged so as to enable smooth flow of production. The standards for chemical pressure vessels in various countries are compared, and considerably high allowable stress is adopted in Europe. The design and stress analysis of pressure vessels are carried out in accordance with ASME Section 8, Div. 1 or Div. 2. As for the materials, attention must be paid to the change of properties due to heat and strain, temper brittleness, low temperature toughness and so on. The quality assurance system must be established to observe the requirements of standards. (Kako, I.)

Full Text Available This article attempts to understand how Thomas Wright’s 1604 work, The Passions of the Minde in Generall, might have fitted into his overall mission as an English Catholic preacher, particularly when read via Wright’s understanding of Thomas Aquinas’s passion of fuga seu abominatio. Some historians claim that Wright was a controversialist, previously describing The Passions as either a radical departure from Wright’s mission, or the work of a different Thomas Wright. Earlier attempts to find a missionary element within The Passions have been inadequate. Through a close reading of The Passions, specifically analysing Wright'ʹs interpretation of fuga seu abominatio within the context of Wright’s intended readership, the main message of The Passions, and his background, this article suggests a possible reading of the text as a work aimed specifically at fellow English Catholics. To Wright, the passions of hatred of abomination and flight or detestation, derived primarily from Aquinas’s fuga seu abominatio, were not simply a form of disgust, as often assumed, but the potential worldly or otherworldly harm that someone we love, such as a neighbour, might face from the abominable evil of sin and damnation. By linking hatred of abomination, flight or detestation, and Wright’s particular view of sin together, Wright was teaching English Catholics how these passions might be used to cure diseased souls, turning the work into a guide for preaching.

Full Text Available In his most recent contribution to an important and well-framed series of papers on auditory grouping and the perception of polyphonic music, David Huron seeks further evidence for his working hypothesis that J.S. Bach controls the employment of perfect consonances by desynchronizing their onsets, thereby inhibiting the perceptual fusion of polyphonic voices. However the more novel contribution of the present study would seem to be its demonstration that Bach also regulates the employment of dissonant tones by consistently desynchronizing their onsets. This finding provides the first concrete evidence for Wright and Bregman’s otherwise untested hypothesis that the control and salience of dissonance in polyphonic music are closely related to principles of auditory stream segregation (Wright, 1986; Wright & Bregman, 1987.

To investigate comprehensive synaptic connectivity, we examined Ca{sup 2+} responses with quantitative electric current stimulation by indium-tin-oxide (ITO) glass electrode with transparent and high electro-conductivity. The number of neurons with Ca{sup 2+} responses was low during the application of stepwise increase of electric current in short-term cultured neurons (less than 17 days in-vitro (DIV)). The neurons cultured over 17 DIV showed two-type responses: S-shaped (sigmoid) and monotonous saturated responses, and Scatchard plots well illustrated the difference of these two responses. Furthermore, sigmoid like neural network responses over 17 DIV were altered to the monotonous saturated ones by the application of the mixture of AP5 and CNQX, specific blockers of NMDA and AMPA receptors, respectively. This alternation was also characterized by the change of Hill coefficients. These findings indicate that the neural network with sigmoid-like responses has strong synergetic or cooperative synaptic connectivity via excitatory glutamate synapses. - Highlights: • We succeed to evaluate the maturation of neural network by Scathard and Hill Plots. • Long-term cultured neurons showed two-type responses: sigmoid and monotonous. • The sigmoid-like increase indicates the cooperatevity of neural networks. • Excitatory glutamate synapses cause the cooperatevity of neural networks.

The paper compares the predictions of two different types of sea scatter theories with recent scatterometer measurements which indicate the variations of the backscattering coefficient with polarization, incident angle, wind speed, and azimuth angle. Wright's theory (1968) differs from that of Chan and Fung (1977) in two major aspects: (1) Wright uses Phillips' sea spectrum (1966) while Chan and Fung use that of Mitsuyasu and Honda, and (2) Wright uses a modified slick sea slope distribution by Cox and Munk (1954) while Chan and Fung use the slick sea slope distribution of Cox and Munk defined with respect to the plane perpendicular to the look direction. Satisfactory agreements between theory and experimental data are obtained when Chan and Fung's model is used to explain the wind and azimuthal dependence of the scattering coefficient.

Research results of hard photon technology have been summarized as a part of novel technology development highly utilizing the quantum nature of photon. Hard photon technology refers to photon beam technologies which use photon in the 0.1 to 200 nm wavelength region. Hard photon has not been used in industry due to the lack of suitable photon sources and optical devices. However, hard photon in this wavelength region is expected to bring about innovations in such areas as ultrafine processing and material synthesis due to its atom selective reaction, inner shell excitation reaction, and spatially high resolution. Then, technological themes and possibility have been surveyed. Although there are principle proposes and their verification of individual technologies for the technologies of hard photon generation, regulation and utilization, they are still far from the practical applications. For the photon source technology, the laser diode pumped driver laser technology, laser plasma photon source technology, synchrotron radiation photon source technology, and vacuum ultraviolet photon source technology are presented. For the optical device technology, the multi-layer film technology for beam mirrors and the non-spherical lens processing technology are introduced. Also are described the reduction lithography technology, hard photon excitation process, and methods of analysis and measurement. 430 refs., 165 figs., 23 tabs.

2014-05-01
Full Text Available Infrastructure we have become accustomed to using in a different manner by the cyber city is at the heart of what today is known as the "smart city", in which the whole range of technologies are at the service of the city both to improve the quality of life and ensure its sustainability. The smart approach to the city construction and transformation finds its roots in the concept of Cyberspace. This is a wide open field, still partially undetermined, which cannot be reduced to one of its components. It serves to interconnect all the devices concerning creation, recording, communication and simulation. In order to illustrate the smart approach to placemaking - meant as the art of making place for people - and implicitly the achieving of a better quality of life, the new DIV@TER multimedia platform, in course of development, is proposed. Div@ter is a dynamic and interactive platform for the complex-sensitive management of the qualitative data of a territory, whose research project has been financed by POR FESR Lazio Region 2007/2013 Axis 1- Activity 1.1. The synthesis of the Esplanade area in Helsinki case study will complete the paper. This case is in line with the projects and relative goals carried out by Forum Virium Helsinki 2015, which is developing new urban digital services. Among these, the Smart City Project Area is devoted to the development of digital urban services for easier travelling and living in the city through the use of mobile devices which are integrated into everyday objects and activities.

The class analysis of poverty: is the underclass living off the socially available surplus?
Chernomas, R; Sepehri, A
1997-01-01
In a recent article Erik Olin Wright argues that the U.S. underclass is a drain on the socially available surplus and thus a hindrance to capital accumulation. Wright's argument is not supported by available evidence from the United States, Canada, and the United Kingdom on the state's distributive activities. This evidence suggests that the social welfare necessary to sustain the underclass is provided by transfers from wage and salary earners rather than from profit.

For developing laser process technology by interaction between substance and photon, the present state, system, R and D issues and proposal of such technology were summarized. Development of the photon technology aims at the modification of bonding conditions of substances by quantum energy of photon, and the new process technology for generating ultra- high temperature and pressure fields by concentrating photon on a minute region. Photon technology contributes to not only the conventional mechanical and thermal forming and removal machining but also function added machining (photon machining) in quantum level and new machining technology ranging from macro- to micro-machining, creating a new industrial field. This technology extends various fields from the basis of physics and chemistry to new bonding technology. Development of a compact high-quality high-power high-efficiency photon source, and advanced photon transmission technology are necessary. The basic explication of an unsolved physicochemical phenomenon related to photon and substance, and development of related application technologies are essential. 328 refs., 147 figs., 13 tabs.

Currently the transfer of chemical technology is a process that contributes to the technology policy of a country, an industry or an organization in general chemistry. This process requires the application of clear criteria for the proper development of the complex interrelations in the transfer of chemical technology. A group of criteria that are present, are those related to environmental technology which intrinsically define the technology and its impact to the environment. Therefore, the ...

Don Quixote Pond: A Small Scale Model of Weathering and Salt Accumulation
Englert, P.; Bishop, J. L.; Patel, S. N.; Gibson, E. K.; Koeberl, C.
2015-01-01
The formation of Don Quixote Pond in the North Fork of Wright Valley, Antarctica, is a model for unique terrestrial calcium, chlorine, and sulfate weathering, accumulation, and distribution processes. The formation of Don Quixote Pond by simple shallow and deep groundwater contrasts more complex models for Don Juan Pond in the South Fork of Wright Valley. Our study intends to understand the formation of Don Quixote Pond as unique terrestrial processes and as a model for Ca, C1, and S weathering and distribution on Mars.

2001-01-01
Crispin Wright hat die bislang beste Rekonstruktion von Putnams Beweis gegen die skeptische Hypothese vom Gehirn im Tank vorgelegt. Aber selbst in Wrights Fassung hat der Beweis einen Mangel: Er wird mithilfe eines Prädikates wie z.B. "Tiger" geführt und funktioniert nur, wenn man sich darauf verlassen kann, dass es Tiger wirklich gibt. Aber die Skeptikerin bestreitet, über die Existenz von Tigern bescheid zu wissen. Das Problem lässt sich dadurch beheben, dass man den Beweis – statt mit dem ...

E1784K is the most common mixed long QT syndrome/Brugada syndrome mutant in the cardiac voltage-gated sodium channel NaV1.5. E1784K shifts the midpoint of the channel conductance-voltage relationship to more depolarized membrane potentials and accelerates the rate of channel fast inactivation. The depolarizing shift in the midpoint of the conductance curve in E1784K is exacerbated by low extracellular pH. We tested whether the E1784K mutant shifts the channel conductance curve to more depolarized membrane potentials by affecting the channel voltage-sensors. We measured ionic currents and gating currents at pH 7.4 and pH 6.0 in Xenopus laevis oocytes. Contrary to our expectation, the movement of gating charges is shifted to more hyperpolarized membrane potentials by E1784K. Voltage-clamp fluorimetry experiments show that this gating charge shift is due to the movement of the DIVS4 voltage-sensor being shifted to more hyperpolarized membrane potentials. Using a model and experiments on fast inactivation-deficient channels, we show that changes to the rate and voltage-dependence of fast inactivation are sufficient to shift the conductance curve in E1784K. Our results localize the effects of E1784K to DIVS4, and provide novel insight into the role of the DIV-VSD in regulating the voltage-dependencies of activation and fast inactivation. PMID:28898267

Methylmercury is an environmental contaminant that is particularly toxic to the developing central nervous system; cerebellar granule neurons are especially vulnerable. Here, primary cultures of cerebellar granule cells (CGCs) were continuously exposed to methylmercury for up to 16 days in vitro (div). LC50 values were 508 ± 199, 345 ± 47, and 243 ± 45 nM after exposure for 6, 11, and 16 div, respectively. Proteins from cultured mouse CGCs were separated by 2DE. Seventy-one protein spots were identified by MALDI-TOF PMF and MALDI-TOF/TOF sequencing. Prolonged exposure to a subcytotoxic concentration of methylmercury significantly increased non-phosphorylated cofilin both in cell protein extracts (1.4-fold; p < 0.01) and in mitochondrial-enriched fractions (1.7-fold; p < 0.01). The decrease in P-cofilin induced by methylmercury was concentration-dependent and occurred after different exposure times. The percentage of P-cofilin relative to total cofilin significantly decreased to 49 ± 13% vs. control cells after exposure to 300 nM methylmercury for 5 div. The balance between the phosphorylated and non-phosphorylated form of cofilin regulates actin dynamics and facilitates actin filament turnover. Filamentous actin dynamics and reorganization are responsible of neuron shape change, migration, polarity formation, regulation of synaptic structures and function, and cell apoptosis. An alteration of the complex regulation of the cofilin phosphorylation/dephosphorylation pathway could be envisaged as an underlying mechanism compatible with reported signs of methylmercury-induced neurotoxicity.

In this study, a fingerprint of steroid saponins, the major bioactive constituents in the crude extracts from Dioscorea zingiberensis C. H. Wright (DZW), has been established for the first time by high-performance liquid chromatography coupled with evaporative light scattering detector (HPLC-ELSD) and the simultaneous characterization of the steroid saponins by high-performance liquid chromatography coupled with electrospray ionization-mass spectrometry and quadrupole tandem time-of-fight mass analyzers detection (HPLC-ESI-Q/TOF). These HPLC analyses were both carried out on a Welchrom C18 column (250 mm × 4.6 mm I.D., 5 μm) with a mobile phase composed of water and acetonitrile under gradient elution. There were 68 common characteristic peaks in the fingerprints, in which 12 of them were confirmed by comparing their mass spectra and retention times with those of the reference compounds. In order to identify the other unknown peaks, their fragmentation behaviors characteristic for the major groups of steroid saponins from DZW with six types of aglycone skeletons were discussed in detail, and possible MS/MS fragmentation pathways were proposed for aiding the structural identification of these components. According to the summarized fragmentation patterns, these peaks were tentatively assigned by matching their empirical molecular formula with those of the published compounds, or by elucidating their quasi-molecular ions and fragment ions referring to available literature information when the reference standards were unavailable. As a result, 22 steroid saponins were found in DZW for the first time. In addition, the quantitative analysis of the 12 known peaks was accomplished at the same time which indicated that there was a great variability in the amount of these active compounds in different batches in the crude extracts. This approach could demonstrate that the fingerprint could be considered to be a suitable tool to comprehensively improve the quality control

TTA8 - Gas technologies points out the various routes Norway can follow to capitalise on the vast resources of natural gas that will be produced in the years to come by developing a strong technology and competence platform. A broad view is taken for the value creation having as basis the continued gas export from NCS to Europe, but also a strong focus on development of gas resources in other parts of the world. The latter can also be seen as part of international positioning for upstream resources and does also include involvements in projects, and export of technology and products. The TTA has structured the analysis into 3 main areas: Gas transport and processing (pipeline, LNG, other); Gas conversion to fuels, chemicals and materials; CO{sub 2} management. In this report, for each of these areas, scenarios based on a gap analysis are presented. One of the key goals has been to identify pacing and emerging technologies for the next 20 years. Based on this, technologies have been mapped according to importance for future competitiveness and technology ambitions. This also includes primary funding responsibilities (public and/or industry). The road map below reflects the key issues in the proposed strategy. The base level of the figure explains areas that will have to be pursued to maintain Norway's role as a key gas and gas technology provider. The second layer represents near term options and possibilities with a reasonable risk profile that could further enhance the Norwegian position given the resources and drive to further develop this industry. As the top layer we have selected some of our 'dreams', what we may achieve if a progressive approach is followed with a strongly innovation based policy. It is acknowledged by the TTA that Norway cannot be a leading technology player in all aspects of the gas value chain.

>Knowledge construction is dialogically and socio-historically driven and guided. This article aims at identifying discourses used by school teachers around the inclusion of students with disabilities. Twelve school teachers with more than five years' worth of experience were interviewed through a semi-structured tape recorded interview that focused on: students' educational histories, their diagnosis and treatment, their follow-up by hospital teachers, their motor and locomotor abilities, and the teaching-learning processes they were involved in. The transcribed interviews were analyzed from a dialogical perspective. The analysis focused on these topics: a diagnosis; b treatment; c development-learning processes. The classroom teachers built meanings out of a conflict between old and new views of the development of students with neuromotor disorders. As our results show, contact between hospital and school teachers contributed to the understanding of the learning process.

Living technology: exploiting life's principles in technology.
Bedau, Mark A; McCaskill, John S; Packard, Norman H; Rasmussen, Steen
2010-01-01
The concept of living technology-that is, technology that is based on the powerful core features of life-is explained and illustrated with examples from artificial life software, reconfigurable and evolvable hardware, autonomously self-reproducing robots, chemical protocells, and hybrid electronic-chemical systems. We define primary (secondary) living technology according as key material components and core systems are not (are) derived from living organisms. Primary living technology is currently emerging, distinctive, and potentially powerful, motivating this review. We trace living technology's connections with artificial life (soft, hard, and wet), synthetic biology (top-down and bottom-up), and the convergence of nano-, bio-, information, and cognitive (NBIC) technologies. We end with a brief look at the social and ethical questions generated by the prospect of living technology.

Technology Transfer: Marketing Tomorrow's Technology
Tcheng, Erene
1995-01-01
The globalization of the economy and the end of the Cold War have triggered many changes in the traditional practices of U.S. industry. To effectively apply the resources available to the United States, the federal government has firmly advocated a policy of technology transfer between private industry and government labs, in this case the National Aeronautics and Space Administration (NASA). NASA Administrator Daniel Goldin is a strong proponent of this policy and has organized technology transfer or commercialization programs at each of the NASA field centers. Here at Langley Research Center, the Technology Applications Group (TAG) is responsible for facilitating the transfer of Langley developed research and technology to U.S. industry. Entering the program, I had many objectives for my summer research with TAG. Certainly, I wanted to gain a more thorough understanding of the concept of technology transfer and Langley's implementation of a system to promote it to both the Langley community and the community at large. Also, I hoped to become more familiar with Langley's research capabilities and technology inventory available to the public. More specifically, I wanted to learn about the technology transfer process at Langley. Because my mentor is a member of Materials and Manufacturing marketing sector of the Technology Transfer Team, another overriding objective for my research was to take advantage of his work and experience in materials research to learn about the Advanced Materials Research agency wide and help market these developments to private industry. Through the various projects I have been assigned to work on in TAG, I have successfully satisfied the majority of these objectives. Work on the Problem Statement Process for TAG as well as the development of the Advanced Materials Research Brochure have provided me with the opportunity to learn about the technology transfer process from the outside looking in and the inside looking out.

This study examined the relations of preservice science teachers' attitudes towards technology use, technology ownership, technology competencies, and experiences to their self-efficacy beliefs about technological pedagogical content knowledge (TPACK). The present study also investigated interrelations among preservice teachers' attitudes towards technology use, technology ownership, technology competencies, and experiences. The participants of study were 665 elementary preservice science teachers (467 females, 198 males) from 7 colleges in Turkey. The proposed model based on educational technology literature was tested using structural equation modeling. The model testing results revealed that preservice teachers' technology competencies and experiences mediated the relation of technology ownership to their TPACK self efficacy beliefs. The direct relation of their possession of technology to their TPACK self efficacy beliefs was insignificant while the indirect relation through their technology competencies and experiences was significant. The results also indicated there were significant direct effects of preservice teachers' attitudes towards technology use, technology competencies, and experiences on their TPACK self efficacy beliefs.

Survey has been conducted to develop laser processing technology utilizing the interaction between substance and photon. This is a part of the leading research on photon technology development. The photon technology development is aimed at novel technology development highly utilizing the quantum nature of photons. In the field of laser processing, high quality photons are used as tools, special functions of atoms and molecules will be discovered, and processing for functional fabrication (photon machining) will be established. A role of laser processing in industries has become significant, which is currently spreading not only into cutting and welding of materials and scalpels but also into such a special field as ultrafine processing of materials. The spreading is sometimes obstructed due to the difficulty of procurement of suitable machines and materials, and the increase of cost. The purpose of this study is to develop the optimal laser technology, to elucidate the interaction between substance and photon, and to develop the laser system and the transmission and regulation systems which realize the optimal conditions. 387 refs., 115 figs., 25 tabs.

For the application of photon to industrial technologies, in particular, a hard photon technology was surveyed which uses photon beams of 0.1-200nm in wavelength. Its features such as selective atom reaction, dense inner shell excitation and spacial high resolution by quantum energy are expected to provide innovative techniques for various field such as fine machining, material synthesis and advanced inspection technology. This wavelength region has been hardly utilized for industrial fields because of poor development of suitable photon sources and optical devices. The developmental meaning, usable time and issue of a hard photon reduction lithography were surveyed as lithography in ultra-fine region below 0.1{mu}m. On hard photon analysis/evaluation technology, the industrial use of analysis, measurement and evaluation technologies by micro-beam was viewed, and optimum photon sources and optical systems were surveyed. Prediction of surface and surface layer modification by inner shell excitation, the future trend of this process and development of a vacuum ultraviolet light source were also surveyed. 383 refs., 153 figs., 17 tabs.

In the past two years, public and private efforts to promote development and deployment of innovative environmental technologies have shifted from the analysis of barriers to the implementation of a variety of initiatives aimed at surmounting those barriers. Particular attention has been directed at (1) streamlining fragmented technology acceptance processes within and among the states, and (2) alleviating disincentives, created by inadequate or unverified technology cost and performance data, for users and regulators to choose innovative technologies. Market fragmentation currently imposes significant cost burdens on technology developers and inhibits the investment of private capital in environmental technology companies. Among the responses to these problems are state and federal technology certification/validation programs, efforts to standardize cost/performance data reporting, and initiatives aimed at promoting interstate cooperation in technology testing and evaluation. This paper reviews the current status of these initiatives, identifies critical challenges to their success, and recommends strategies for addressing those challenges

Technology and ecological economics. Promethean technology, Pandorian potential

In considering social, economic and ecological impacts of new technologies it is essential to start from an understanding of human nature. This paper explores this issue drawing out some implications for ecological and neoclassical economics. The paper presents two key arguments. First, we argue that there is a growing tension between our evolved human nature and social structures and our emerging technological prowess. Modern technologies give us increasing power to manipulate the very axes of nature: space, time, energy, matter, and life. Technologies are now so powerful they give us abilities our ancestors would consider godlike. The question is posed: Are humans ready to wield the power of the gods? We have the knowledge, but do we have the wisdom? The myth of Prometheus and Pandora is considered as a metaphor for the interaction between technology, nature and universal aspects of human nature developed over eons of evolution. Second, we argue that even a 'technologically optimistic' scenario (employed by some economists) may not actually deliver Utopian outcomes. With technological advancement and diffusion there is a 'technological trickle down effect' whereby potent technologies, once available only to governments and powerful elites, become available to greater numbers of groups and individuals. The more accessible a technology, the more likely its social and ecological impacts will be shaped by the full range and extremes of human nature. These issues have implications for the development and regulation of Promethean technologies such as nuclear energy, genetic engineering and nanotechnology; technologies with unprecedented power and reach through nature. Development and diffusion of such technologies may also have implications for the ethics of the social structure of society. (author)

Technological economics: innovation, project management, and technology transfer
Energy Technology Data Exchange (ETDEWEB)
Bradbury, F R
1981-06-01
The relationship between economics and technology, as well as their interaction in production, productivity, project management, and in technology transfer processes are reviewed. Over the last two decades there has been an increasing interest by economists in the technologist's view of technical change and its mechanisms. The author looks at the zone between technology and economics, the technological economics, and discusses the theory of innovation recently sketched out by Nelson and Winter. The relevance to project management and technology transfer of contemporary writing by economists leads to the view that there are welcome signs of a convergence of the conceptual models now emerging and the practical problems of technology management and movement. Economists now seem more willing to come to terms with technology than technologists with economics. The economic significance of the multitudes of technically unglamorous activities in development work is seriously neglected as a result of over-emphasis on the spectacular technological break. If economic elegance were to be admitted to the criteria of success, one might get a significant improvement in the engineering of technological change. 29 references, 4 figure.

Focus on Technologies: Worry or Technology?
Directory of Open Access Journals (Sweden)
Saulius Kanišauskas
2015-10-01
Full Text Available The paper analyses different attitudes towards technologies in contemporary philosophical discourses. It points out that classical notion of technology formulated by Martin Heidegger seems to be more and more often questioned and even forgotten. As a result, it is being replaced by the theory of determinism, according to which the change of technologies determines the changes in social systems, the human being including. This happens this way and not vice versa. Nowadays technē, or “technika” (in English: technology is mostly understood in the instrumental meaning or in the meaning of power. It is considered to be a powerful means, tool or mechanism to influence, change, control and manipulate human consciousness and human feelings. Despite the fact that technologies have already been tamed, the problem of huge responsibility for using and developing them arises. It is questioned whether the increasing society’s attention to modern technologies is not a particular “technology” of the postmodern capitalism to manipulate social consciousness. In parallel with “yes” answer to this question, Albert Borgmann’s idea that the causes of technological development have an ontological dimension, i.e. the causes are rooted in the nature of human beings themselves and their desire to adore own creativity, is discussed. Thus, it becomes necessary to probe deeper into the nature of creativity.

Carlos Alberto PRADO GUERRERO
2010-06-01
Full Text Available The objective of this study is to analyze the educational practices of using Blackboard in blended learning environments with students of higher education to understand the relationship between technological appropriation and standards of educational technology. To achieve that goal, the following research question was raised: ¿To what extent are the standards of education technology with the appropriation of technology in blended learning environments in higher education related? The contextual framework of this work includes the following topics: the institution, teaching, teachers and students. The design methodology that was used is of a correlation type. Correlations were carried out to determine the frequency and level in the technological standards as well as the appropriation of technology. In the comparison of the results obtained by the students, the teachers and the platform; we found that students in the school study showed a high degree of technology ownership and this was the same for the performance shown on the technological standards. It was established that teachers play a key role in developing the technological appropriation of students and performance in technology standards.

Emerging Technological Risk Underpinning the Risk of Technology Innovation
Anderson, Stuart
2012-01-01
Classes of socio-technical hazards allow a characterization of the risk in technology innovation and clarify the mechanisms underpinning emergent technological risk. Emerging Technological Risk provides an interdisciplinary account of risk in socio-technical systems including hazards which highlight: · How technological risk crosses organizational boundaries, · How technological trajectories and evolution develop from resolving tensions emerging between social aspects of organisations and technologies and · How social behaviour shapes, and is shaped by, technology. Addressing an audience from a range of academic and professional backgrounds, Emerging Technological Risk is a key source for those who wish to benefit from a detail and methodical exposure to multiple perspectives on technological risk. By providing a synthesis of recent work on risk that captures the complex mechanisms that characterize the emergence of risk in technology innovation, Emerging Tec...

New trend in electron holography
Tanigaki, Toshiaki; Harada, Ken; Murakami, Yasukazu; Niitsu, Kodai; Akashi, Tetsuya; Takahashi, Yoshio; Sugawara, Akira; Shindo, Daisuke
2016-06-01
Electron holography using a coherent electron wave is a promising technique for high-resolution visualization of electromagnetic fields in and around objects. The capability of electron holography has been enhanced by the development of new technologies and has thus become an even more powerful tool for exploring scientific frontiers. This review introduces these technologies including split-illumination electron holography and vector-field electron tomography. Split-illumination electron holography, which uses separated coherent waves, overcomes the limits imposed by the lateral coherence requirement for electron waves in electron holography. Areas that are difficult to observe using conventional electron holography are now observable. Exemplified applications include observing a singular magnetic domain wall in electrical steel sheets, local magnetizations at anti-phase boundaries, and electrostatic potentials in metal-oxide-semiconductor field-effect transistors. Vector-field electron tomography can be used to visualize magnetic vectors in three dimensions. Two components of the vectors are reconstructed using dual-axis tomography, and the remaining one is calculated using div B = 0. A high-voltage electron microscope can be used to achieve precise magnetic reconstruction. For example, magnetic vortices have been visualized using a 1 MV holography electron microscope.

On their bumpy road to commercialization, hydrogen production, delivery and conversion technologies not only require dedicated research, development and demonstration efforts, but also protected niche markets and early adopters. While niche markets utilize the unique technological properties of hydrogen, adopters exhibit a willingness to pay a premium for hydrogen fueled energy services. The concept of the technology learning curve is applied to estimate the capital requirements associated with the commercialization process of several hydrogen technologies. (author)

Experimental identification of nitrogen-vacancy complexes in nitrogen implanted silicon
Adam, Lahir Shaik; Law, Mark E.; Szpala, Stanislaw; Simpson, P. J.; Lawther, Derek; Dokumaci, Omer; Hegde, Suri
2001-07-01
Nitrogen implantation is commonly used in multigate oxide thickness processing for mixed signal complementary metal-oxide-semiconductor and System on a Chip technologies. Current experiments and diffusion models indicate that upon annealing, implanted nitrogen diffuses towards the surface. The mechanism proposed for nitrogen diffusion is the formation of nitrogen-vacancy complexes in silicon, as indicated by ab initio studies by J. S. Nelson, P. A. Schultz, and A. F. Wright [Appl. Phys. Lett. 73, 247 (1998)]. However, to date, there does not exist any experimental evidence of nitrogen-vacancy formation in silicon. This letter provides experimental evidence through positron annihilation spectroscopy that nitrogen-vacancy complexes indeed form in nitrogen implanted silicon, and compares the experimental results to the ab initio studies, providing qualitative support for the same.

Mixed Boundary Value Problem on Hypersurfaces
Directory of Open Access Journals (Sweden)
R. DuDuchava
2014-01-01
Full Text Available The purpose of the present paper is to investigate the mixed Dirichlet-Neumann boundary value problems for the anisotropic Laplace-Beltrami equation divC(A∇Cφ=f on a smooth hypersurface C with the boundary Γ=∂C in Rn. A(x is an n×n bounded measurable positive definite matrix function. The boundary is decomposed into two nonintersecting connected parts Γ=ΓD∪ΓN and on ΓD the Dirichlet boundary conditions are prescribed, while on ΓN the Neumann conditions. The unique solvability of the mixed BVP is proved, based upon the Green formulae and Lax-Milgram Lemma. Further, the existence of the fundamental solution to divS(A∇S is proved, which is interpreted as the invertibility of this operator in the setting Hp,#s(S→Hp,#s-2(S, where Hp,#s(S is a subspace of the Bessel potential space and consists of functions with mean value zero.

Serotonin (5-HT) neurons contribute to respiratory chemoreception in adult mice, but it is unclear whether they play a similar role in neonatal mice. We studied breathing during development in Lmx1bf/f/p mice, which lack 5-HT neurons. From postnatal days 1–7 (P1–P7), ventilation of Lmx1bf/f/p mice breathing room air was 50% of WT mice (p acidosis until 12 days in vitro (DIV), after which their response increased to reach a plateau around 25 DIV. Neonatal Lmx1bf/f/p mice displayed high mortality and decreased growth rate, and this worsened in hypoxia. Mortality was decreased in hyperoxia. These results indicate that maturation of 5-HT neurons contributes to development of respiratory CO2/pH chemoreception during the first few weeks of life in mice in vivo. A defect in the 5-HT system in early postnatal life decreases survival due in part to hypoxia. PMID:27619736

1978-01-01
Since about three or four years ago, the enterprises of machinery, iron and steel and welding materials in Japan are paying much attention to the acquisition of ASME (American Society of Mechanical Engineers) certificates or authorization to stamp the code symbols. That is, over 70 factories in Japan have undergone ASME examination, and consequently acquired the authorization or certificates. Such authorization is divided into over 20 kinds, of which about 7 are possessed by the companies in Japan. In nuclear field, the kinds of authorization are N (nuclear vessel), NPT (nuclear vessel parts), NV (nuclear vessel safety valve), and MM (material manufacturing). In non-nuclear fields, they are S (power boilers), U (pressure vessels, in Div. 1), and U2 (pressure vessels in Div. 2). The following matters are described: ASME setup, authorization procedures of ASME for factories, the kinds of authorization, factories in Japan holding the authorization or certificates, and renewal of the authorization.
