    The 1.5 m telescope GREGOR opens a new window to the understanding of solar small-scale magnetism. The first light instrumentation includes the Gregor Fabry Pérot Interferometer (GFPI), a filter spectro-polarimeter for the visible wavelength range, the GRating Infrared Spectro-polarimeter (GRIS) and the Broad-Band Imager (BBI). The excellent performance of the first two instruments has already been demonstrated at the Vacuum Tower Telescope. GREGOR is Europe's largest solar telescope and number 3 in the world. Its all-reflective Gregory design provides a large wavelength coverage from the near UV up to at least 5 microns. The field of view has a diameter of 150 arcsec. GREGOR is equipped with a high-order adaptive optics system, with a subaperture size of 10 cm, and a deformable mirror with 256 actuators. The science goals are focused on, but not limited to, solar magnetism. GREGOR allows us to measure the emergence and disappearance of magnetic flux at the solar surface at spatial scales well below 100 km. Thanks to its spectro-polarimetric capabilities, GREGOR will measure the interaction between the plasma flows, different kinds of waves, and the magnetic field. This will foster our understanding of the processes that heat the chromosphere and the outer layers of the solar atmosphere. Observations of the surface magnetic field at very small spatial scales will shed light on the variability of the solar brightness.

  3. Gregor Mendel, OSA (1822-1884), founder of scientific genetics.

    Dunn, P M

    2003-11-01

    Gregor Mendel, an Augustinian monk and part-time school teacher, undertook a series of brilliant hybridisation experiments with garden peas between 1857 and 1864 in the monastery gardens and, using statistical methods for the first time in biology, established the laws of heredity, thereby establishing the discipline of genetics.

    2012-11-01

    In this review, we look back upon the literature, which had the GREGOR solar telescope project as its subject including science cases, telescope subsystems, and post-focus instruments. The articles date back to the year 2000, when the initial concepts for a new solar telescope on Tenerife were first presented at scientific meetings. This comprehensive bibliography contains literature until the year 2012, i.e., the final stages of commissioning and science verification. Taking stock of the various publications in peer-reviewed journals and conference proceedings also provides the ``historical'' context for the reference articles in this special issue of Astronomische Nachrichten/Astronomical Notes.

  5. Historical study: Johann Gregor Mendel 1822-1884.

    Weiling, F

    1991-07-01

    The life and personality of Johann Gregor Mendel (1822-1884), the founder of scientific genetics, are reviewed against the contemporary background of his times. At the end are weighed the benefits for Mendel (as charged by Sir Ronald Fisher) to have documented his results on hand of falsified data. Mendel was born into a humble farm family in the "Kuhländchen", then a predominantly German area of Northern Moravia. On the basis of great gifts Mendel was able to begin higher studies; however, he found himself in serious financial difficulties because of his father's accident and incapacitation. His hardships engendered illness which threatened continuation and completion of his studies until he was afforded the chance of absolving successfully theological studies as an Augustinian monk in the famous chapter of St. Thomas in Altbrünn (Staré Brno). Psychosomatic indisposition made Mendel unfit for practical pastoral duties. Thus, he was directed to teach but without appropriate state certification; an attempt to pass such an examination failed. At that point he was sent to the University of Vienna for a 2-year course of studies, with emphasis on physics and botany, to prepare him for the exam. His scientific and methodologic training enabled him to plan studies of the laws of inheritance, which had begun to interest him already during his theology training, and to choose the appropriate experimental plant. In 1865, after 12 years of systematic investigations on peas, he presented his results in the famous paper "Versuche über Pflanzenhybriden." Three years after his return from Vienna he failed to attain his teaching certification a second time. Only by virtue of his exceptional qualifications did he continue to function as a Supplementary Professor of Physics and Natural History in the two lowest classes of a secondary school. In 1868 he was elected Abbot of his chapter, and freed from teaching duties, was able to pursue his many scientific interests with greater

  10. Karlin–McGregor-like formula in a simple time-inhomogeneous birth–death process

    Ohkubo, Jun

    2014-01-01

    Algebraic discussions are developed to derive transition probabilities for a simple time-inhomogeneous birth–death process. Algebraic probability theory and Lie algebraic treatments make it easy to treat the time-inhomogeneous cases. As a result, an expression based on the Charlier polynomials is obtained, which can be considered as an extension of a famous Karlin–McGregor representation for a time-homogeneous birth–death process.

  11. sTools - a data reduction pipeline for the GREGOR Fabry-Pérot Interferometer and the High-resolution Fast Imager at the GREGOR solar telescope

    Kuckein, C.; Denker, C.; Verma, M.; Balthasar, H.; González Manrique, S. J.; Louis, R. E.; Diercke, A.

    2017-10-01

    A huge amount of data has been acquired with the GREGOR Fabry-Pérot Interferometer (GFPI), large-format facility cameras, and since 2016 with the High-resolution Fast Imager (HiFI). These data are processed in standardized procedures with the aim of providing science-ready data for the solar physics community. For this purpose, we have developed a user-friendly data reduction pipeline called ``sTools'' based on the Interactive Data Language (IDL) and licensed under creative commons license. The pipeline delivers reduced and image-reconstructed data with a minimum of user interaction. Furthermore, quick-look data are generated as well as a webpage with an overview of the observations and their statistics. All the processed data are stored online at the GREGOR GFPI and HiFI data archive of the Leibniz Institute for Astrophysics Potsdam (AIP). The principles of the pipeline are presented together with selected high-resolution spectral scans and images processed with sTools.

  12. The Karlin-McGregor formula for a variant of a discrete version of Walsh's spider

    Gruenbaum, F Alberto

    2009-01-01

    We consider a variant of a discrete space version of Walsh's spider, see Walsh (1978 Temps Locaux, Asterisque vol 52-53 (Paris: Soc. Math. de France)) as well as Evans and Sowers (2003 Ann. Probab. 31 486-527 and its references). This process can be seen as an instance of a quasi-birth-and-death process, a class of random walks for which the classical theory of Karlin and McGregor can be nicely adapted as in Dette, Reuther, Studden and Zygmunt (2006 SIAM J. Matrix Anal. Appl. 29 117-42), Gruenbaum (2007 Probability, Geometry and Integrable Systems ed Pinsky and Birnir vol 55 (Berkeley, CA: MSRI publication) pp. 241-60, see also arXiv math PR/0703375), Gruenbaum (2007 Dagstuhl Seminar Proc. 07461 on Numerical Methods in Structured Markov Chains ed Bini), Gruenbaum (2008 Proceedings of IWOTA) and Gruenbaum and de la Iglesia (2008 SIAM J. Matrix Anal. Appl. 30 741-63). We give here a weight matrix that makes the corresponding matrix-valued orthogonal polynomials orthogonal to each other. We also determine the polynomials themselves and thus obtain all the ingredients to apply a matrix-valued version of the Karlin-McGregor formula.

  13. Gregor Mendel's classic paper and the nature of science in genetics courses.

    Westerlund, Julie F; Fairbanks, Daniel J

    2010-12-01

    The discoveries of Gregor Mendel, as described by Mendel in his 1866 paper Versuche uber Pflanzen-Hybriden (Experiments on plant hybrids), can be used in undergraduate genetics and biology courses to engage students about specific nature of science characteristics and their relationship to four of his major contributions to genetics. The use of primary source literature as an instructional tool to enhance genetics students' understanding of the nature of science helps students more clearly understand how scientists work and how the science of genetics has evolved as a discipline. We offer a historical background of how the nature of science developed as a concept and show how Mendel's investigations of heredity can enrich biology and genetics courses by exemplifying the nature of science. © 2010 The Authors.

  14. MuSICa at GRIS: a prototype image slicer for EST at GREGOR

    Calcines, A.; Collados, M.; López, R. L.

    2013-05-01

    This communication presents a prototype image slicer for the 4-m European Solar Telescope (EST) designed for the spectrograph of the 1.5-m GREGOR solar telescope (GRIS). The design of this integral field unit has been called MuSICa (Multi-Slit Image slicer based on collimator-Camera). It is a telecentric system developed specifically for the integral field, high resolution spectrograph of EST and presents multi-slit capability, reorganizing a bidimensional field of view of 80 arcsec^{2} into 8 slits, each one of them with 200 arcsec length × 0.05 arcsec width. It minimizes the number of optical components needed to fulfil this multi-slit capability, three arrays of mirrors: slicer, collimator and camera mirror arrays (the first one flat and the other two spherical). The symmetry of the layout makes it possible to overlap the pupil images associated to each part of the sliced entrance field of view. A mask with only one circular aperture is placed at the pupil position. This symmetric characteristic offers some advantages: facilitates the manufacturing process, the alignment and reduces the costs. In addition, it is compatible with two modes of operation: spectroscopic and spectro-polarimetric, offering a great versatility. The optical quality of the system is diffraction-limited. The prototype will improve the performances of GRIS at GREGOR and is part of the feasibility study of the integral field unit for the spectrographs of EST. Although MuSICa has been designed as a solar image slicer, its concept can also be applied to night-time astronomical instruments (Collados et al. 2010, Proc. SPIE, Vol. 7733, 77330H; Collados et al. 2012, AN, 333, 901; Calcines et al. 2010, Proc. SPIE, Vol. 7735, 77351X)

    The Carseland-Bow River Headworks (CBRH) is a major multi-purpose water delivery system, situated in southern Alberta. It supplies water to 87,000 hectares of agricultural land and several municipalities. The system was originally built starting in 1909. It consists of diversion works on the Bow River, 65 kilometres of canal, and the McGregor and Little Bow reservoirs. In the 1950s, the system was rehabilitated by the Prairie Farm Rehabilitation Administration (PFRA), and Travers Reservoir was added in 1954. In 1973, ownership and operation of the CBRH system was turned over to Alberta Environment. In 2001, Alberta Transportation implemented a major program to rehabilitate and upgrade the CBRH system. This program included increasing the capacity of the canals and structures, and upgrading the dams to meet current dam safety guidelines. The project involved raising the north and south dams, providing an auxiliary spillway to accommodate the probable maximum flood (PMF), and rehabilitating the existing reservoir inlet and low level outlet structures. This paper discussed the abandonment of the existing low level outlet structure located within the south dam. The paper discussed the existing dams and outlet structure as well as the south dam and outlet structure. The abandonment of the existing low level outlet structure was discussed in terms of general construction; demolition; upstream conduits and gatewell; and downstream conduit. Several illustrations and photographs of the dam and the demolition were presented. It was concluded that the in-place abandonment of the existing low level outlet structure at the McGregor South Dam provides significant advantages, including eliminating the need to construct and remove an extensive cofferdam within the reservoir. 6 refs., 2 tabs., 4 figs.

    The GREGOR Fabry-Pérot Interferometer (GFPI) is one of three first-light instruments of the German 1.5-m GREGOR solar telescope at the Observatorio del Teide, Tenerife, Spain. The GFPI allows fast narrow-band imaging and postfactum image restoration. The retrieved physical parameters will be a fundamental building block for understanding the dynamic sun and its magnetic field at spatial scales down to ˜50 km on the solar surface. The GFPI is a tunable dual-etalon system in a collimated mounting. It is designed for spectrometric and spectropolarimetric observations between 530-860 nm and 580-660 nm, respectively, and possesses a theoretical spectral resolution of R≈250,000. Large-format, high-cadence charged coupled device detectors with sophisticated computer hard- and software enable the scanning of spectral lines in time-spans equivalent to the evolution time of solar features. The field-of-view (FOV) of 50″×38″ covers a significant fraction of the typical area of active regions in the spectroscopic mode. In case of Stokes-vector spectropolarimetry, the FOV reduces to 25″×38″. The main characteristics of the GFPI including advanced and automated calibration and observing procedures are presented. Improvements in the optical design of the instrument are discussed and first observational results are shown. Finally, the first concrete ideas for the integration of a second FPI, the blue imaging solar spectrometer, are laid out, which will explore the blue spectral region below 530 nm.

    2014-07-01

    Integral Field Spectroscopy is an innovative technique that is being implemented in the state-of-the-art instruments of the largest night-time telescopes, however, it is still a novelty for solar instrumentation. A new concept of image slicer, called MuSICa (Multi-Slit Image slicer based on collimator-Camera), has been designed for the integral field spectrograph of the 4-m European Solar Telescope. This communication presents an image slicer prototype of MuSICa for GRIS, the spectrograph of the 1.5-m GREGOR solar telescope located at the Observatory of El Teide. MuSICa at GRIS reorganizes a 2-D field of view of 24.5 arcsec into a slit of 0.367 arcsec width by 66.76 arcsec length distributed horizontally. It will operate together with the TIP-II polarimeter to offer high resolution integral field spectropolarimetry. It will also have a bidimensional field of view scanning system to cover a field of view up to 1 by 1 arcmin.

    2016-07-01

    An image slicer has been proposed for the Integral Field Spectrograph [1] of the 4-m European Solar Telescope (EST) [2] The image slicer for EST is called MuSICa (Multi-Slit Image slicer based on collimator-Camera) [3] and it is a telecentric system with diffraction limited optical quality offering the possibility to obtain high resolution Integral Field Solar Spectroscopy or Spectro-polarimetry by coupling a polarimeter after the generated slit (or slits). Considering the technical complexity of the proposed Integral Field Unit (IFU), a prototype has been designed for the GRIS spectrograph at GREGOR telescope at Teide Observatory (Tenerife), composed by the optical elements of the image slicer itself, a scanning system (to cover a larger field of view with sequential adjacent measurements) and an appropriate re-imaging system. All these subsystems are placed in a bench, specially designed to facilitate their alignment, integration and verification, and their easy installation in front of the spectrograph. This communication describes the opto-mechanical solution adopted to upgrade GRIS while ensuring repeatability between the observational modes, IFU and long-slit. Results from several tests which have been performed to validate the opto-mechanical prototypes are also presented.

  20. The evolutionary ideas of F. M. (Ladimir) Klacel, teacher of Gregor Mendel.

    Peaslee, Margaret H; Orel, Vitezslav

    2007-06-01

    Abstract: A philosopher and teacher, F. M. (Ladimir) Klacel (1808-1882), educated in what is now the Czech Republic, developed his own explanation for the origin and interaction of living organisms. Klácel, a member of the Augustinian Monastery in Brno, influenced his younger colleague, Friar Gregor Mendel, who went on to formulate concepts in heredity that are still recognized for their profound insight. A mutual interest in the natural sciences of these two friends provided a basis for their discussions of the relationship between religion, evolution, and society. Klacel's outspoken defense of his proposals caused him to lose favor with both the Church and the authorities, and he immigrated to America in 1869. His failing health and inability to communicate with the English-speaking populace, unfortunately, limited his influence in his new environs. In this paper we trace the roots of Klacel's philosophy and elucidate his incorporation of ideas from Hegel, Darwin, and others. An investigation of Klacel's recipe for a successful society reveals his belief in the universality of life and his optimistic hope for human achievement.

  1. From the peas of Gregor Mendel to the human genome and beyond

    Paces, V

    2008-01-01

    In the middle of the 19th century, Gregor Mendel conducted his experiments with peas. This took place in the Augustinian monastery in Brno (now the Czech Republic), where he was the abbot. These experiments laid the foundations of modern genetics. At around the same time Charles Darwin formulated his theory of evolution. Through their work, these two men inaugurated the age of modern biology. The next most important step came in 1953 when James Watson and Francis Crick solved the elusive DNA structure. Since then methods for ‘reading’ genetic information have developed quickly, and genomes of many organisms have been analysed, including our own. The human genome consists of 3 billion letters (nucleotides) and it comprises approximately 25,000 genes. The smallest natural genome is the genome of Mycoplasma genitalium. It consists of a mere 500,000 nucleotides and is composed of 500 genes. Yet, mycoplasma is capable of a completely independent life. It would appear from this fact that basic life itself is no...

  2. Involvement of Three Esterase Genes from Panonychus citri (McGregor in Fenpropathrin Resistance

    Xiao-Min Shen

    2016-08-01

    Full Text Available The citrus red mite, Panonychus citri (McGregor, is a major citrus pest with a worldwide distribution and an extensive record of pesticide resistance. However, the underlying molecular mechanism associated with fenpropathrin resistance in this species have not yet been reported. In this study, synergist triphenyl phosphate (TPP dramatically increased the toxicity of fenpropathrin, suggesting involvement of carboxylesterases (CarEs in the metabolic detoxification of this insecticide. The subsequent spatiotemporal expression pattern analysis of PcE1, PcE7 and PcE9 showed that three CarEs genes were all over-expressed after insecticide exposure and higher transcripts levels were observed in different field resistant strains of P. citri. Heterologous expression combined with 3-(4,5-dimethyl-thiazol-2-yl-2,5-diphenyltetra-zolium bromide (MTT cytotoxicity assay in Spodoptera frugiperda (Sf9 cells revealed that PcE1-, PcE7- or PcE9-expressing cells showed significantly higher cytoprotective capability than parental Sf9 cells against fenpropathrin, demonstrating that PcEs probably detoxify fenpropathrin. Moreover, gene silencing through the method of leaf-mediated dsRNA feeding followed by insecticide bioassay increased the mortalities of fenpropathrin-treated mites by 31% (PcE1, 27% (PcE7 and 22% (PcE9, respectively, after individual PcE gene dsRNA treatment. In conclusion, this study provides evidence that PcE1, PcE7 and PcE9 are functional genes mediated in fenpropathrin resistance in P. citri and enrich molecular understanding of CarEs during the resistance development of the mite.

  5. The human side of science education: Using McGregor's theory Y as a framework for improving student motivation*.

    Markwell, John

    2004-09-01

    Student motivation is correlated with learning. Douglas McGregor's Theory X and Theory Y as a basis for understanding and improving motivation in the business world can be directly applied to the science classroom. Teachers with a Theory Y perspective (students naturally want to learn) provide increased motivation for students and promote more active learning than Theory X-style teachers who do not view students as active learners. Many teachers are not aware of their Theory X/Theory Y orientation and how this bias may be impacting their interaction with students. This article explores the benefits of moving from a Theory X to a more Theory Y style of teaching. Copyright © 2004 International Union of Biochemistry and Molecular Biology, Inc.

    Oligonychus ilicis (McGregor) is among those mite species that can cause damage to coffee plants (Coffea spp.). Species of Phytoseiidae acari are considered the most important and studied predatory mites. The objective of this study was to evaluate the effects of the webbing produced by O. ilicis on its predation by females of the phytoseiids Iphiseiodes zuluagai Denmark and Muma, Euseius citrifolius Denmark and Muma and Amblyseius herbicolus (Chant). Four bioassays were conducted, with three treatments and ten replicates. Each replicate consisted of 25 O. ilicis per experimental unit (a leaf disc of Coffea arabica) according to the tested developmental stage, in independent experiments. To spin the web, 15 adult females were put on each experimental unit for 24h; females were then removed, leaving only the web, and predators and prey to be tested were introduced. Predation was assessed after 24h. In the presence of webbing, the consumption of eggs, larvae and nymphs by I. zuluagai and eggs and larvae by E. citrifolius was lower. For A. herbicolus, egg predation was lower, but larval predation did not vary significantly and predation of nymphs and adults was higher in the presence of webbing. Predators as a whole were more efficient consuming larvae regardless of the presence of webbing. Considering the stages of O. ilicis altogether, webbing reduced the predation potential of I. zuluagai and E. citrifolius, but not of A. herbicolus. (author)

To spin the web, 15 adult females were put on each experimental unit for 24h; females were then removed, leaving only the web, and predators and prey to be tested were introduced. Predation was assessed after 24h. In the presence of webbing, the consumption of eggs, larvae and nymphs by I. zuluagai and eggs and larvae by E. citrifolius was lower. For A. herbicolus, egg predation was lower, but larval predation did not vary significantly and predation of nymphs and adults was higher in the presence of webbing. Predators as a whole were more efficient consuming larvae regardless of the presence of webbing. Considering the stages of O. ilicis altogether, webbing reduced the predation potential of I. zuluagai and E. citrifolius, but not of A. herbicolus. (author)

  8. High-cadence Imaging and Imaging Spectroscopy at the GREGOR Solar Telescope—A Collaborative Research Environment for High-resolution Solar Physics

    In high-resolution solar physics, the volume and complexity of photometric, spectroscopic, and polarimetric ground-based data significantly increased in the last decade, reaching data acquisition rates of terabytes per hour. This is driven by the desire to capture fast processes on the Sun and the necessity for short exposure times “freezing” the atmospheric seeing, thus enabling ex post facto image restoration. Consequently, large-format and high-cadence detectors are nowadays used in solar observations to facilitate image restoration. Based on our experience during the “early science” phase with the 1.5 m GREGOR solar telescope (2014–2015) and the subsequent transition to routine observations in 2016, we describe data collection and data management tailored toward image restoration and imaging spectroscopy. We outline our approaches regarding data processing, analysis, and archiving for two of GREGOR’s post-focus instruments (see http://gregor.aip.de), i.e., the GREGOR Fabry–Pérot Interferometer (GFPI) and the newly installed High-Resolution Fast Imager (HiFI). The heterogeneous and complex nature of multidimensional data arising from high-resolution solar observations provides an intriguing but also a challenging example for “big data” in astronomy. The big data challenge has two aspects: (1) establishing a workflow for publishing the data for the whole community and beyond and (2) creating a collaborative research environment (CRE), where computationally intense data and postprocessing tools are colocated and collaborative work is enabled for scientists of multiple institutes. This requires either collaboration with a data center or frameworks and databases capable of dealing with huge data sets based on virtual observatory (VO) and other community standards and procedures.

    Full Text Available O objetivo do trabalho foi avaliar a toxicidade residual de alguns agrotóxicos utilizados em citros sobre Neoseiulus californicus (McGregor em condições de laboratório. O método de bioensaio adotado foi o de contato residual. Folhas de citros da variedade Pêra, acondicionadas em arenas, foram pulverizadas em torre de Potter. A toxicidade residual dos produtos foi avaliada duas horas e 1; 3; 5; 7; 10; 14 e 21 dias após a aplicação. Em cada arena, foram transferidas dez fêmeas adultas de N. californicus, juntamente com uma quantidade suficiente de Tetranychus urticae, como fonte de alimento. As avaliações de mortalidade foram realizadas 72 horas após a transferência dos ácaros para as arenas. Os agrotóxicos acrinathrin, deltamethrin, dinocap, enxofre, fenpropathrin, óxido de fenbutatin e propargite não causaram mortalidades significativas em adultos de N. californicus. Foram registradas mortalidades de 29,8; 24,0 e 34,1% para ácaros N. californicus expostos a resíduos de duas horas de idade de abamectim, azocyclotin e cyhexatin, respectivamente. Dicofol, pyridaben e chlorfenapyr causaram 100% de mortalidade aos ácaros predadores expostos aos resíduos tóxicos dos acaricidas, com duas horas de idade. Abamectin provocou mortalidade significativa por um período inferior a um dia. Resíduos dos acaricidas azocyclotin, cyhexatin, dicofol, pyridaben e chlorfenapyr provocaram mortalidades significativas por períodos de 1; 1; 10; 10 e 21dias, respectivamente. Os resultados obtidos no presente experimento servem de subsídio para a escolha adequada dos agrotóxicos a serem utilizados em pomares de citros nos quais N. californicus esteja presente ou naqueles em que o predador venha a ser liberado. Esses resultados também servem para a escolha do momento mais favorável para a liberação dos ácaros predadores dessa espécie no campo, após a aplicação de agrotóxicos nos pomares.

    Paleček, Pavel

    2016-09-01

    At almost 90 years of age, we have lost the author of the founding historical works on Johann Gregor Mendel. Vítězslav Orel served for almost 30 years as the editor of the journal Folia Mendeliana. His work was beset by the wider problems associated with Mendel's recognition in the Communist Bloc, and by the way in which narratives of the history of science could be co-opted into the service of Cold War and post-Cold War political agendas. Orel played a key role in the organization of the Mendel symposium of 1965 in Brno, and has made a strong contribution to the rehabilitation of genetics generally, and to championing the work of Johann Gregor Mendel in particular. With Jaroslav Kříženecký, he cofounded the Mendelianum in Brno, which for decades has served as an intellectual bridge between the East and West. Orel's involvement with this institution exposed him to dangers both during and after the Cold War.

    Full Text Available In the present study determined the side effects of four acaricides of acequinocyl, etoxazole, bifenazate and milbemectin on the predator mites Phytoseiulus persimilis Athias-Henriot and Neoseiulus californicus McGregor. Acaricide concentrations were prepared as a two times the field application dose (2T, field application dose (T, and half of the field application dose (T/2 and were then applied on eggs, nymphs and adults of the P. persimilis and N. californicus. The side effects of the acaricidesapplied to the predator mites were determined three, five and seven days afterthe application. While all doses of acequinocyl and etoxazole showed a higher toxic effect on N.californicus eggs, it was found that bifenazate and milbemectin caused similar effects on both predator mite eggs. Furthermore, it was found that the toxic effects of acequinocyl, etoxazole, bifenazate and milbemectin on nymphs and adults of the predator miteswere high seventh day after the application. The results of the study showed that four acaracides frequently used against to pest mites, should be used more carefully in the agricultural areas.

    Full Text Available The predatory mite, Neoseiulus californicus(McGregor, 1954 (Acari: Phytoseiidae is one of the principal natural enemies of tetranychid mites in several countries, promoting efficient control of those mites in several food and ornamental crops. Pest attacks such as that of the spider mite, Tetranychus urticaeKoch, 1836 (Acari: Tetranychidae, is one of the problems faced by farmers, especially in the greenhouse, due to the difficulty of its control with the use of chemicals because of the development of fast resistance making it hard to control it. The objective of this work was to study the life history of the predatory mite N. californicus as a contribution to its mass laboratory rearing, having castor bean plant [Ricinus communis L. (Euphorbiaceae] pollen as food, for its subsequent use as a natural enemy of T. urticae on a cultivation of greenhouse rosebushes. The studies were carried out in the laboratory, at 25 ± 2°C of temperature, 70 ± 10% RH and a 14 hour photophase. The biological aspects and the fertility life table were appraised. Longevity of 32.9 days was verified for adult females and 40.4 days for males. The intrinsic rate of increase (rm was 0.2 and the mean generation time (T was 17.2 days. The population doubled every 4.1 days. The results obtained were similar to those in which the predatory mite N. californicus fed on T. urticae.

  16. FORSTERIAN MODEL OF CHARACTERIZATION AND NON-HUMAN CHARACTERS IN NARRATIVE FICTION: IRIS MURDOCH’S MISTER MARS AND FRANZ KAFKA’S GREGOR SAMSA

    Barış METE

    2017-06-01

    Full Text Available In Aspects of the Novel, Edward Morgan Forster introduces the critical concepts of flat and round to describe the nature of different types of fictional characters. According to Forster’s theoretical categorization, flat characters are constructed and exist in their fictional realm around a single feature or quality. As this is the key criterion, Forster argues that flat characters can easily be recognized and remembered by the reader. Flat characters remain mostly the same through circumstances. In other words, flat characters never surprise the reader. Contrary to the nature of flat characters, round characters operate in an opposite direction to their counterparts. Round characters never remain the same throughout events, and it is not easy to recognize them since they do not exist under the dominance of a single trait. In addition to these, round characters are those who surprise the reader. Although Forster’s categorisation of fictional characters has functioned well in most of the cases, some characters are not easily analysed under this formula. Franz Kafka’s Gregor Samsa, for example, seems neither a round nor a flat character. Throughout his story, he remains the same. At the same time, he surprises the reader, which is not expected from him since he is mostly the same character in the text. Samsa’s turning into an insect further complicates the definition of his roundness or flatness. Another example is Iris Murdoch’s Mister Mars. Mister Mars is an animal. But at the same time he is a movie star, a celebrity. He has a pivotal role for the protagonist of the text. Therefore, the aim of this study is first to introduce the theoretical background of the nature of fictional characters and then to display some difficulties present particularly in Forster’s classification through the characterisation of two non-human examples.

    Full Text Available The oviposition preference of the red mite Oligonychus yothersi McGregor was evaluated under laboratory in 52 Paraguay tea progenies and one control collected in a local farm. The experiments were conducted on Paraguay tea leaf discs infested with one adult female mite/disc, incubated in a climate chamber (25±1ºC, 14h photophase for five days. Evaluations were performed daily, by counting the number of eggs laid in the period, the number of female escapes in the first 48 hours, as well as the number of eggs laid before the escaping. It was verified that discrimination by the mite occurred on two groups of progenies, in relation to the number of eggs: one group was different from the control (53.8% of the progenies and the other was identical to it (46.2% of the progenies. In the first group, 60.7% of progenies were less oviposited while a higher number of eggs/female than the control was verified in 39.3% of them. In 57.7% of progenies there was escape of some mites (10 to 40%, and in 10 of these progenies no eggs were laid. The data provide evidences that in some of the progenies evaluated there is resistance by non-preference to oviposition of the Paraguay tea red mite.A preferência para oviposição do ácaro-vermelho, Oligonychus yothersi McGregor, foi avaliada em condições de laboratório em 52 progênies de erva-mate e uma testemunha coletada em uma propriedade da região.

Ácaros da família Phytoseiidae, de várias espécies, são eficientes predadores associados aos ácaros-praga. Conduziu-se este trabalho com o objetivo de estudar o controle dos ácaros-praga com spirodiclofen e azocyclotin, e o impacto sobre fitoseídeos. Em laboratório foram estudados os efeitos ovicida, tópico, residual, tópico mais residual e a seletividade fisiológica aos fitoseídeos; em casa-de-vegetação foi avaliada a persistência no controle às duas espécies de ácaros-praga; e em campo foi avaliada a eficiência apenas no controle de B. phoenicis. Os bioensaios foram realizados em arenas de folhas destacadas. O efeito ovicida foi avaliado em ovos no início e final de incubação. Os efeitos residual, tópico e tópico mais residual foram avaliados pela mortalidade de larvas, ninfas e adultos aos oito dias, e a persistência até 30 dias após a aplicação. A seletividade aos fitoseídeos foi avaliada, pelo efeito na mortalidade e reprodução de fêmeas adultas, em teste residual em superfície de vidro. Spirodiclofen e azocyclotin (SC mostraram eficiente ação ovicida, principalmente para ovos de B. phoenicis no início de incubação. Para ovos de O. ilicis, somente o spirodiclofen apresentou efeito ovicida. Em geral, os efeitos tópico e residual associados melhoraram a eficiência dos produtos no controle das fases pós-embrionárias de ambas as espécies. O spirodiclofen apresentou seletividade aos ácaros predadores, já o azocyclotin foi nocivo.

    The maintenance of horizontal gaze is an essential function of upright posture and global sagittal spinal alignment. Horizontal gaze is classically measured by the chin-brow vertical angle (CBVA), which is not readily measured on most lateral spine radiographs. To evaluate relations between CBVA and the slope of the line of sight, the slope of McGregor's line (McGS), and Oswestry Disability Index. Patients were identified from a single center database of 531 spine patients who underwent full-body EOS x-rays. Correlations between CBVA, the slope of the line of sight, and McGS were assessed. Using a quadratic regression with Oswestry Disability Index and CBVA, windows of low disability were identified. Comparison of sagittal spinopelvic parameters was carried out between patients with "ascending gaze" and "neutral position." Three hundred three patients were included (74% female, mean age 54.8 years, body mass index 26.6 ± 6.0 kg/m). CBVA strongly correlated with the slope of the line of sight (r = 0.996) and McGS (r = 0.862). Regression studies between Oswestry Disability Index and CBVA yielded a range of values corresponding to low disability (-4.7 degrees to 17.7 degrees). Similarly, a low disability range for the slope of the line of sight (-5.1 degrees to 18.5 degrees) and McGS (-5.7 degrees to 14.3 degrees) was computed. Patients with "ascending gaze" had a worse spinopelvic alignment than "neutral position" patients. The slope of the line of sight and McGS correlated strongly with CBVA and can be used as surrogate measures. The range of values for these measures corresponding to low disability was identified. These values can be used as a general guideline to assess alignment for diagnostic purposes. Cervical compensatory mechanism may modify the natural head position in sagittally misaligned patients.

  15. [1848: Gregor Mendel, the monk who wanted to be a citizen].

    2006-04-01

    This article proposes a previously unpublished French translation of a petition, in German, addressed by six Augustinian friars to the Constitutional Parliament of Vienna in the revolutionary year 1848. The petition states that members of religious orders are deprived of civil rights and demands that they be given citizenship ; it also contains a bitter attack on the monastic institution. We suggest that Mendel was the author of this text, which he signed and actually hand-wrote.

  17. Inoculate Release of Stethorus gilvifrons Mulsan (Coleoptera: Coccinellidae for Biological Control of Date Palm Spider Mite, Oligonychus afrasiaticusMcGregor (Prostigmata: Tetranychidae

    M. Latifian

    2017-12-01

    Full Text Available Introduction: The spider mite, Oligonychus afrasiaticus feeds by sucking the sap from the immature fruits tissue. The natural color of fruits changes to pale yellow or gray by mite's feeding. Damaged fruit are cracked and its damage can dry out the fruits. Because of resistance to pesticides, resurgence of date palm spider mite causes to disrupt the natural balance of their population. Tiny black ladybird beetle, Stethorous gilvifrons is the most important and active lady beetle species in Khuzestan province and is very effective on biological control of the spider mite. Determination of the amount and release time of the lady beetles are the most important factors in the implementation of biological control programs of date palm spider mite. So, careful monitoring, time of the release and the ability of deployment of predatory ladybird are essential steps to success in the programs of biological control. Materials and Methods: This research was conducted in Shadegan region of Khuzestan province. The nested design was used to compare the efficiency of different inoculate release methods of the predator, S. gilvifrons. The main niches include three release times which were at the time of emergence, three days and one week after emergence of date palm spider mite in date palm plantation. Sub nesting including three different levels of predator release including minimum, moderate and maximum release with 0.5, 1 and 3 predator /m2 per day and were continued for two weeks. The two or three-days ladybirds were used to release. First, the infected clusters were covered by mesh fabric and ladybirds were released under them. After a week, mantles were opened up to the establishment of ladybird run on the normal condition of date palm plantations. This experiment was repeated three times, and each replication consists of a quarter- hectare plantation with dominant cultivar Sayer.Three date Palm trees from each release and control were randomly selected. One hundred fruits from10 major's of each bunches were randomly selected and the number of spider mite (prey and coccinellid (predator were counted in different developmental stages. The relationship between predator and prey was calculated by using Pearson's correlation in different treatments as an index of density-dependent reaction of the predator to prey density and its establishment. Results and Discussion: Results showed that there were significant difference between treatments of release on seasonal mite and lady beetle populations and the average seasonal growth reduction rate at 1% probability level. The maximum difference in the number of mite – infested treatment and control occurred at maximum release with predatory mite. The maximum density of the lady beetle population was observed around mid to late June. Date palm fruits were been at Kharg phonological growth at this time and they had the greatest sensitivity to the mite population. The highest correlation coefficient occurred in terms of release time coincided with the moderate and maximum release of spider mite´s predator. So, the predator showed density - depend reaction and its establishment were occurred. Release of three and one lady beetle/m2 and simultaneously with the appearance of spider mite had powerful and significant correlation. In those circumstances, the density-dependent response of lady beetle was observed. The prey and the predator population densities have several fluctuations around their equilibrium level during the season. Number of predator population declines and prey population increases from their equilibrium levels were reduced by the simultaneous release of the predator to start prey activities. The predatory failure establishment is zero in the maximum release.The highest control of date palm spider mite was about 83.28% at release treatments. In all releasing treatments, the level of biological control was increased with increasing the number of coccinelid releases per unit. Conclusions: The highest predator efficiency were calculated in the maximum release (3 coccinellid per square meter and simultaneously with the appearance of spider mite in date palm plantation. The control performance was 83.27 percent in this condition. Understanding of the fluctuations of the date palm pests and their natural enemies and the effect of climatic factors on the fluctuations are necessary to operate the proposed models for biological date palm pest control. The success of this predator is high in terms of the date ecosystem, and the susceptibility of palm fruit to pests decreased at the end of the season.

  18. Revisitando a perspectiva de James MacGregor Burns: qual é a ideia por trás do conceito de liderança transformacional?

    Pedro Alessandro Calaça

    Full Text Available Na Administração, a liderança é vinculada ao interesse na eficiência produtiva, tendo como pressuposto a capacidade de líderes e liderados atingirem os resultados organizacionais. Todavia, a liderança é matéria mais ampla do que pode julgar essa concepção. Por entender que essa é a perspectiva adotada no texto seminal de Burns (1978 sobre liderança transformacional, propomos neste estudo revisitar essa obra, para contrapor seus principais argumentos em relação àqueles formulados por autores de liderança transformacional na área de Administração. Para tanto, adotamos a análise sócio-histórica, como proposta por Stefani e Vizeu (2011, a primeira etapa da hermenêutica de profundidade (THOMPSON, 2000, um método que visa a evitar o erro da livre interpretação de uma obra contextualmente situada. Assim, concluímos que o ponto central da liderança transformacional, para Burns, é a questão do desenvolvimento moral e o distanciamento na relação utilitária entre líder e liderados. Esses dois pontos são reforçados ao longo do texto pelos exemplos dados pelo autor, quase sempre relacionados ao contexto da liderança no âmbito político e dos movimentos sociais, onde a questão ético-moral é tomada em uma dimensão societal.

  1. Desarrollo de un proyecto agrícola en la región marginal de la Patagonia Meridional Argentina. El caso de Gobernador Gregores

    María Eugenia Cepparo de Grosso

    2012-02-01

    Full Text Available Santa Cruz, provincia ubicada en el extremo sur del territorio continental argentino, posee un ambiente fuertemente condicionado por la fragilidad de sus características naturales y una situación socioeconómica tradicionalmente orientada a la monoactividad ganadera en el área rural y a los servicios públicos en los centros urbanos. En ese marco, y durante la década de 1990, surgió una iniciativa apoyada por organismos del Estado y financiada por bancos provinciales para estimular un proyecto agrícola adaptado a las limitadas aptitudes agrícolas de la región. Un reducido número de agricultores, inquietos por generar actividades que diversificaran el tradicional modelo pastoril, experimentaron los dilemas de los comienzos y las crisis de un proyecto de estímulo económico en un territorio marginal. Este trabajo contribuye con una serie de reflexiones acerca de las motivaciones que justifican el estudio de pequeñas sociedades en áreas marginales; de la confrontación entre el marco conceptual de la marginalidad según los países centrales y los periféricos; y del accionar y el compromiso de los actores sociales motivados por una alternativa de desarrollo local en una localidad ubicada en el centro de la Patagonia Meridional Argentina.

  20. Er3+ infrared fluorescence affected by spatial distribution synchronicity of Ba2+ and Er3+ in Er3+-doped BaO–SiO2 glasses

    Atsunobu Masuno

    2016-02-01

    Full Text Available Glasses with the composition xBaO–(99.9 − xSiO2–0.1ErO3/2 (0 ≤x ≤ 34.9 were fabricated by a levitation technique. The glasses in the immiscibility region were opaque due to chemical inhomogeneity, while the other glasses were colorless and transparent. The scanning electron microscope observations and electron probe microanalysis scan profiles revealed that more Er3+ ions were preferentially distributed in the regions where more Ba2+ ions existed in the chemically inhomogeneous glasses. The synchronicity of the spatial distributions of the two ions initially increased with increasing x and then decreased when the Ba2+ concentration exceeded a certain value. The peak shape and lifetime of the fluorescence at 1.55 μm depended on x as well as the spatial distribution of both ions. These results indicate that although ErOn polyhedra are preferentially coordinated with Ba2+ ions and their local structure is affected by the coordination of Ba2+, there is a maximum in the amount of Ba2+ ions that can coordinate ErOn polyhedra since the available space for Ba2+ ions is limited. These findings provide us with efficient ways to design the chemical composition of glasses with superior Er3+ fluorescence properties for optical communication network systems.

    This topical issue of Astronomische Nachrichten/Astronomical Notes is a collection of reference articles covering the GREGOR solar telescope, its science capabilities, its subsystems, and its dedicated suite of instruments for high-resolution observations of the Sun. Because ground-based telescopes have life spans of several decades, it is only natural that they continuously reinvent themselves. Literally, the GREGOR telescope builds on the foundations of the venerable Gregory-Coudé Telescope (GCT) at Observatorio del Teide, Tenerife, Spain. Acknowledging the fact that new discoveries in observational solar physics are driven by larger apertures to collect more photons and to scrutinize the Sun in finer detail, the GCT was decommissioned and the building was made available to the GREGOR project.

  8. Theory X/Y in the Health Care Setting: Employee Perceptions, Attitudes, and Behaviors.

    Prottas, David J; Nummelin, Mary Rogers

    Douglas McGregor's conceptualization of Theory X and Theory Y has influenced management practices for almost six decades, despite the relative paucity of empirical support. This empirical study examined the relationships between health care employees' perceptions of (1) manager Theory Y and Theory X orientations; (2) work unit psychological safety, organizational citizenship behavior, and service quality; and (3) the employing entity. The study used survey data from more than 3500 employees of a large US health care system and analyzed them using confirmatory factor and hierarchical regression analyses. Results indicate that McGregor's conceptualization is best considered as two separate constructs-Theory Y and Theory X-rather than as one-dimensional X/Y construct. This study's three dependent variables were positively related to Theory Y and negatively related to Theory X, with larger Theory Y effect sizes. Psychological safety partially mediated the relationship between Theory Y and the dependent variables Y. Practical implications are presented.

  2. Capture and Utilization of Water From Rain: The Way for Sustainable School

    Jamila El Tugoz

    2017-05-01

    Full Text Available Currently, issues related to environmental preservation and responsible use of water, have become a global concern, which has driven the increasing number of public policies aimed at promoting sustainable practices. In this context, it addresses the implementation of a system harnessing rainwater for non-potable purposes in a school unit. This article aimed to evaluate the results obtained from the use of tanks to capture and use of rainwater in a state school of Paraná, in the city of Marechal Cândido Rondon. It is a descriptive exploratory research, qualitative and quantitative approach. Based on data from historical series water consumption of the College Eron Domingues, a relationship between the consumption of water and the monthly rainfall for the period was established. The results confirmed the efficiency of the capture of rain water system, reducing the consumption of treated water supplied by the Water and Sewage Company, up 57.2%. Thus, while stimulating in students an awareness focused on sustainability, inclusion of knowledge and environmental practices at school, comprise the prospect of a multiplier effect on society.

  3. Erbium environments in erbium-silicon/silica light emitting nanostructures

    Kashtiban, R J; Bangert, U; Crowe, I F; Halsall, M P

    2011-01-01

    Co-doping of SiO 2 with Si and Er to achieve silica fibre amplifiers has resulted in encouraging levels of light emission, much above those of Er-only doped SiO 2 . However, different fabrication methods, i.e., co-implantion and sequential implantation of Er and Si, has led to several factors difference in light levels. This paper looks into the reasons for these differences by establishing structure and local stoichiometry of the created entities via analytical transmission electron microscopy. In both cases Si-nanocrystals (NCs) have formed in the SiO 2 matrix. In the former case Er-ions are co-located with /integrated within the NCs, in the latter case NCs and Er are separate. By assessing the NCs' internal and interfacial structure with the surrounding material, we attempt to identify chemical/structural Er-phases/defects and their effect on the sensitising efficiency in the Er:Si-NCs system; high resolution phase contrast- and high angle dark field imaging as well as nano-scale spatially resolved electron energy core loss- and plasmon-spectroscopy carried out in an aberration corrected dedicated STEM lend valuable support to these studies.

  4. Long-term Effects of Parents' Education on Children's Educational and Occupational Success: Mediation by Family Interactions, Child Aggression, and Teenage Aspirations.

    Dubow, Eric F; Boxer, Paul; Huesmann, L Rowell

    2009-07-01

    We examine the prediction of individuals' educational and occupational success at age 48 from contextual and personal variables assessed during their middle childhood and late adolescence. We focus particularly on the predictive role of the parents' educational level during middle childhood, controlling for other indices of socioeconomic status and children's IQ, and the mediating roles of negative family interactions, childhood behavior, and late adolescent aspirations. Data come from the Columbia County Longitudinal Study, which began in 1960 when all 856 third graders in a semi-rural county in New York State were interviewed along with their parents; participants were reinterviewed at ages 19, 30, and 48 (Eron et al, 1971; Huesmann et al., 2002). Parents' educational level when the child was 8 years old significantly predicted educational and occupational success for the child 40 years later. Structural models showed that parental educational level had no direct effects on child educational level or occupational prestige at age 48 but had significant indirect effects that were independent of the other predictor variables' effects. These indirect effects were mediated through age 19 educational aspirations and age 19 educational level. These results provide strong support for the unique predictive role of parental education on adult outcomes 40 years later and underscore the developmental importance of mediators of parent education effects such as late adolescent achievement and achievement-related aspirations.

  7. DNA barcoding as a screening tool for cryptic diversity

    Huemer, Peter; Karsholt, Ole; Mutanen, Marko

    2014-01-01

    We explore the potential value of DNA barcode divergence for species delimitation in the genus Caryocolum Gregor & Povolný, 1954 (Lepidoptera, Gelechiidae), based on data from 44 European species (including 4 subspecies). Low intraspecific divergence of the DNA barcodes of the mtCOI (cytochrome c...... oxidase 1) gene and/or distinct barcode gaps to the nearest neighbor support species status for all examined nominal taxa. However, in 8 taxa we observed deep splits with a maximum intraspecific barcode divergence beyond a threshold of 3%, thus indicating possible cryptic diversity. The taxonomy...

  10. Cd translocation into generative organs of linseed (Linum usitatissimum L.)

    Becher, M.; Woerner, A.; Schubert, S. [Giessen Univ. (Germany). Inst. fuer Pflanzenernaehrung

    1997-12-31

    Linseed is able to accumulate considerably high concentrations of Cd in generative organs, the dietary critical value of 0.3 {mu}g Cd/g seed often being exceeded. Differences between genotypes of linseed in this respect, however, have been observed but the underlying mechanisms responsible for these differences are unknown. The aim of the present work was to identify these mechanisms by studying the Cd accumulation of the linseed genotypes Antares and McGregor which differ in their ability to accumulate Cd in the seeds. Cultivar Antares is a high and cv. McGregor is low Cd accumulator which was confirmed in a pot experiment. It was found that the differences between these genotypes were Cd-specific and were caused neither by single seed weight nor by Cd translocation into the shoot. The distribution pattern of Cd within mature capsules between the pericarp and the seeds differed from that of Ca which was used as a phloem-immobile reference ion. From these results we conclude that Cd was translocated from the pericarp into the seeds via the phloem. This conclusion was supported by direct Cd determination in collected phloem sap from linseed stems. As sources of seed-Cd we identified the pericarps of capsules and the leaves. The genotype differences concerning the Cd concentrations in the seeds may be explained in terms of differences in phloem translocation of Cd. (orig.)

Das Ziel der vorliegenden Arbeit bestand darin, diese Mechanismen an den Oelleinsorten Antares und McGregor zu untersuchen. Antares akkumuliert grosse, McGregor hingegen geringe Mengen Cd in den Samen. Diese Beobachtungen konnten in einem Gefaessversuch bestaetigt werden. Es wurde gezeigt, dass die

    Full Text Available Ever since Gregor Johan Mendel proposed the law of inheritance, genetics has transcended the field of health and has entered all walks of life in its application. Thus, the gene is the pivoting factor for all happenings revolving around it. Knowledge of gene mapping in various diseases would be a valuable tool in prenatally diagnosing the condition and averting the future disability and stigma for the posterity. This article includes an array of genetically determined conditions in patients seen at our college out-patient department with complete manifestation, partial manifestation and array of manifestations not fitting into a particular syndrome.

    Theory X, Theory Y and Theory Z in organizational behaviour (OB) are related to human motivation and management. Theory X and Y were coined by Douglas McGregor in the late 1960s, says that the average human being is lazy and self-centred, lacks ambition, dislikes change, and longs to be told what to do. The corresponding managerial approach emphasizes total control. Theory Y maintains that human beings are active rather than passive shapers of themselves and of their environment. They long to...

  6. Theories for the winds from Wolf Rayet stars

    Cassinelli, J.P.

    1982-01-01

    The massive and fast winds of Wolf Rayet stars present a serious momentum problem for the line-driven wind theories that are commonly used to explain the fast winds of early type stars. It is perhaps possible for the winds to be driven by lines, if multiple scattering occurs and if there are a sufficient number of lines in the spectrum so that large fraction of the continuum is blocked by line opacity in the winds. Several other mechanisms are discussed, in particular two that rely on strong magnetic fields: a) Alfven wave driven wind models like those recently developed by Hartmann and MacGregor for late type supergiants and b) the ''Fast Magnetic Rotator'' model that was developed by Belcher and MacGregor for the winds from pre-main sequence stars. In either model, large magnetic fields (approximately equal to 10 4 gauss) are required to drive the massive and fast winds of Wolf Rayet stars. Smaller fields might be possible if the multiple scattering line radiation force can be relied on to provide a final acceleration to terminal velocity. (Auth.)

  7. Contactless sub-millimeter displacement measurements

    Sliepen, Guus; Jägers, Aswin P. L.; Bettonvil, Felix C. M.; Hammerschlag, Robert H.

    2008-07-01

    Weather effects on foldable domes, as used at the DOT and GREGOR, are investigated, in particular the correlation between the wind field and the stresses caused to both metal framework and tent clothing. Camera systems measure contactless the displacement of several dome points. The stresses follow from the measured deformation pattern. The cameras placed near the dome floor do not disturb telescope operations. In the set-ups of DOT and GREGOR, these cameras are up to 8 meters away from the measured points and must be able to detect displacements of less than 0.1 mm. The cameras have a FireWire (IEEE1394) interface to eliminate the need for frame grabbers. Each camera captures 15 images of 640 × 480 pixels per second. All data is processed on-site in real-time. In order to get the best estimate for the displacement within the constraints of available processing power, all image processing is done in Fourier-space, with all convolution operations being pre-computed once. A sub-pixel estimate of the peak of the correlation function is made. This enables to process the images of four cameras using only one commodity PC with a dual-core processor, and achieve an effective sensitivity of up to 0.01 mm. The deformation measurements are well correlated to the simultaneous wind measurements. The results are of high interest to upscaling the dome design (ELTs and solar telescopes).

  8. Biological control of Eotetranychus lewisi and Tetranychus urticae (Acari: Tetranychidae) on strawberry by four phytoseiids (Acari: Phytoseiidae).

    Howell, Anna D; Daugovish, Oleg

    2013-02-01

    The spider mite, Eotetranychus lewisi (McGregor) (Acari: Tetranychidae), is a new emerging pest in California commercial strawberries. The predatory mite Phytoseiulus persimilis (Athias-Henriot) (Acari: Phytoseiidae), typically used for biocontrol of Tetranychus urticae (Koch) (Acari: Tetranychidae), provided growers little to no control of E. lewisi. Four commonly used phytoseiid predatory mites: P. persimilis, Neoseiulus californicus (McGregor), N. fallacis (Garman), and Amblyseius andersoni (Chant), were used in lab studies to investigate which is best at managing E. lewisi populations. We als o investigated t he interactions between T. urticae and E. lewisi and in relation to phytoseiid efficiency given the potential for indirect effects of biocontrol. When E. lewisi and T. urticae are present on the same leaf, T. urticae populations increase and begin displacing E. lewisi. P. persimilis did not feed on E. lewisi, but the other three predatory mites consumed the spider mites and lowered their populations. When both E. lewisi and T. urticae are present on the same leaf, N. fallacis and A. andersoni fed on both types of mites equally and were capable of decreasing both populations. N. californicus fed on E. lewisi first and decreased its population, but allowed T. urticae populations to increase. P. persimilis may be insufficient at controlling E. lewisi and its use may instead enhance E. lewisi populations.

    Full Text Available La violencia es uno de los principales problemas sociales de Venezuela; existe evidencia empírica de que la impunidad y el aumento de la posesión de armas son elementos que contribuyen a incrementar el número de homicidios. Aun sin guerra en el país, la violencia interpersonal de la cotidianidad afecta a todos; es expresión de normas y pautas culturales que sirven de soporte a comportamientos agresivos. Es un contexto en el cual la sensación de indefensión sirve de justificación a conductas de aprobación de acciones extrajudiciales de la policía y a estar dispuesto a matar a los delincuentes. Al respecto, se realizó una investigación que tenía como objetivo central analizar la problemática de la violencia urbana en Venezuela a través de la exploración de diversas áreas, una de la cuales es la relativa a las normas y la cultura, cuyos resultados se describen en este artículo.

    The El Paso County Geothermal Project at Fort Bliss was an effort to determine the scale and scope of geothermal resources previously identified on Fort Bliss’ McGregor Range in southern Otero County, New Mexico. The project was funded with a $5,000,000 grant to El Paso County from the U.S. Department of Energy (DOE) as part of the American Recovery and Reinvestment Act of 2009 and a $4,812,500 match provided by private sector partners. The project was administered through the DOE Golden Field Office to awardee El Paso County. The primary subcontractor to El Paso County and project Principal Investigator - Ruby Mountain Inc. (RMI) of Salt Lake City, Utah - assembled the project team consisting of Evergreen Clean Energy Management (ECEM) of Provo, Utah, and the Energy & Geoscience Institute at the University of Utah (EGI) in Salt Lake City, UT to complete the final phases of the project. The project formally began in May of 2010 and consisted of two preliminary phases of data collection and evaluation which culminated in the identification of a drilling site for a Resource Confirmation Well on McGregor Range. Well RMI 56-5 was drilled May and June 2013 to a depth of 3,030 ft. below ground level. A string of slotted 7 inch casing was set in 8.75 inch hole on bottom fill at 3,017 ft. to complete the well. The well was drilled using a technique called flooded reverse circulation, which is most common in mineral exploration. This technique produced an exceptionally large and complete cuttings record. An exciting development at the conclusion of drilling was the suspected discovery of a formation that has proven to be of exceptionally high permeability in three desalinization wells six miles to the south. Following drilling and preliminary testing and analysis, the project team has determined that the McGregor Range thermal anomaly is large and can probably support development in the tens of megawatts.

    Meyer, Bente Tobiesen

    of tablets into classrooms will enroll devices in networks of learning that establish new and significant relationships between learning technologies such as iPads, whiteboards, pcs as well as books, pens and paper. These relationships challenge the idea that iPads can act as isolated and unique actors......Research in learning technologies has often focused on the affordances of single technologies such as pcs, smartphones or interactive whiteboards (Meyer 2013). However, in most learning environments technologies do not stand alone but are embedded in activity structures and webs of materials...... that make up the learning activity (Fenwick, Edwards and Sawchuk 2011, Lawn and Grosvenor 2005, McGregor 2003, Nespor 2002). This is specifically relevant when the object of study is mobile learning, where devices are flexible and follow the learner in his/her shifting learning activities and needs (Burden...

  13. Perspectives on the dental school learning environment: putting theory X and theory Y into action in dental education.

    Connor, Joseph P; Troendle, Karen

    2008-12-01

    Theory X and Theory Y are terms coined by Douglas McGregor to express the belief that managers' behaviors are shaped by their assumptions about the motivation of their subordinates. The theories were applied to dental education in a Perspectives article published in the August 2007 issue of the Journal of Dental Education. This article explains how those seemingly contradictory theories can be reconciled using the concept of the "emotional bank account" introduced by Stephen Covey in The 7 Habits of Highly Effective People. Understanding the underlying concept of an emotional bank account helps dental educators to bridge the generation gap between instructors, born during the baby boom period of 1946-63, and dental students, born after 1980, who are referred to as "Generation Y" or "millennials."

  14. Displaying lives: the narrative of objects in biographical exhibitions

    Caterina Albano

    2007-03-01

    Full Text Available Biographical exhibitions are a museum practice that asks for critical consideration. Grounding the argument in critical theory, social studies and museum theory, the article explores the narrative function of objects in biographical exhibitions by addressing the social significance of objects in relation to biography and their relevance when presented into an exhibition display. Central is the concept of objects as ‘biographical relics’ that are culturally fetishized in biographical narratives. This raises questions about biographical reliability and the cultural role that such objects plays in exhibition narratives as bearers of reality and as metonymical icons of the biographical subject. The article considers examples of biographical exhibitions of diverse figures such as Gregor Mendel, Madame de Pompadour and Roland Barthes, and the role that personal items, but also portraits and photographs, play in them.

  15. Does genomic imprinting play a role in autoimmunity?

    Camprubí, Cristina; Monk, David

    2011-01-01

    In the 19th century Gregor Mendel defined the laws of genetic inheritance by crossing different types of peas. From these results arose his principle of equivalence: the gene will have the same behaviour whether it is inherited from the mother or the father. Today, several key exceptions to this principle are known, for example sex-linked traits and genes in the mitochondrial genome, whose inheritance patterns are referred to as 'non mendelian'. A third, important exception in mammals is that of genomic imprinting, where transcripts are expressed in a monoallelic fashion from only the maternal or the paternal chromosome. In this chapter, we discuss how parent-of-origin effects and genomic imprinting may play a role in autoimmunity and speculate how imprinted miRNAs may influence the expression of many target autoimmune associated genes.

    Næsted, Henrik; Svensson, Birte

    (MacGregor A.W.). Here we present the recent results of the expression and characterization of the recombinant full length barley high pI α-glucosidase in Pichia Pastoris. In order to facilitate in the range of mg protein yield, a clone representing an N-terminal hexa histidine tagged recombinant form...... of the enzyme was grown under high cell-density fermentation conditions. This approach enabled a successful protein expression profile under the highly sensitive methanol utilization phase of the fermentation procedure. The enzyme was purified using a four step purification strategy. Interestingly, the purified...... enzyme exhibits a higher molecular mass than expected from its primary sequence when applied on SDS-PAGE, indicating a possible post translational modification of the recombinant α-glucosidase. Preliminary enzyme kinetic analysis has demonstrated that the purified α-glucosidase is “fully” active when...

  18. National Calendar-2009

    2009-10-01

    The calendar represents a few hundreds of biographies of scientists, artists and writers from everywhere, printed in chronological order and adjusted to their birthdays. A number of international and national holydays, including some refering to science are included in the Calendar. A great deffect of the Calendar is the introduction in the list of holydays of the "international day of astrology". Another defect is the absence of the indication of the membership to Communist Parties for persons cited from the former USSR and former Communist Countries. The following physicists, astronomers and mathematicians had biographies in the actual issue: Kon, Lia Z., Arnautov, Vladimir I. (math), Tsukerblat, B., Kapitza, P., Donici (Donitch), N.N., Sklodowska-Curie, Maria, da Vinci, Leonardo, Birkhof, George David, Galilei, Galileo, Pisarzhveskij, Lev (chemist), Mossbauer, Rudolf Ludwig, Clochisner (Klokishner), Sofia I., Miscoi (Mishkoy), Gh.

  19. Shape parameters explain data from spatial transformations: comment on Pearce et al. (2004) and Tommasi & Polli (2004).

    Cheng, Ken; Gallistel, C R

    2005-04-01

    In 2 recent studies on rats (J. M. Pearce, M. A. Good, P. M. Jones, & A. McGregor, see record 2004-12429-006) and chicks (L. Tommasi & C. Polli, see record 2004-15642-007), the animals were trained to search in 1 corner of a rectilinear space. When tested in transformed spaces of different shapes, the animals still showed systematic choices. Both articles rejected the global matching of shape in favor of local matching processes. The present authors show that although matching by shape congruence is unlikely, matching by the shape parameter of the 1st principal axis can explain all the data. Other shape parameters, such as symmetry axes, may do even better. Animals are likely to use some global matching to constrain and guide the use of local cues; such use keeps local matching processes from exploding in complexity.

  20. British energy policy and the market for coal - minutes of evidence - Tuesday 1 December 1992

    1992-12-01

    The Committee set up to examine UK energy policy and the market for coal (particularly British Coal's place in that market), examined evidence from: Mr David Porter, Mr Neil Bryson, Mr Fergus Wiggin and Mr John Macadam (Association of Independent Electricity Producers); Mr John Collins, Mr John Wybrew, Dr Chris Fay and Mr Ian Wybrew-Bond (Shell UK Ltd); Sir James McKinnon and Mr Greg McGregor (Office of Gas Supply (OFGAS)). Aspects covered include consequences of British Coal's pit closure programme, UK natural gas reserves, and the effects of increased demand for natural gas due to the 'dash for gas' (i.e. generating electricity from natural gas rather than coal).

  2. Motivating pharmacists.

    Donehew, G R

    1979-01-01

    Although pharmacists are developing interest in many types of pharmacy practice, they are still spending the bulk of their time in the prescription dispensing process. Any effort to provide motivation must consider the prescription dispensing process. The pharmacy literature includes only a few studies that dealt with pharmacists as people. The studies usually showed that pharmacists basically were unhappy with their jobs. In developing a motivational climate for pharmacists, pharmacy supervisors have several concepts to consider: the hierarchy of needs by Maslow; the expectancy theory by Hampton; the gygiene-motivator theory by Herzberg; and the Theory Y management approach by McGregor. Because pharmacists must be induced to enter and remain in an organization, supervisors should be aware of the need to use any technique available in developing a motivational climate.

  3. A impossibilidade de se dizer o indizível: reflexões sobre o duplo na novela “O unicórnio”, de Hilda Hilst

    2014-01-01

    Full Text Available This study aims at reflecting on the raise of the double in the novella “O unicórnio”, by Hilda Hilst, as an evidence of one’s impossibility to express what cannot be expressed. Echoing Gregor Samsa’s uncanny experience, the novella’s narrator suddenly becomes an awkward, absurd creature. A double of the narrator, this new “I” she becomes makes explicit the devious relation, built throughout the text, between a deep necessity of comprehending the world and a world that is closed in its silence, denying to be comprehended. Interpreting the raise of this double-unicorn as the main evidence of this confront, we hope to draw, in the following lines, some reflections on the limits of the language in face of the unspeakable.

  4. Motivating pharmacy employees.

    White, S J; Generali, J A

    1984-07-01

    Concepts from theories of motivation are used to suggest methods for improving the motivational environment of hospital pharmacy departments. Motivation--the state of being stimulated to take action to achieve a goal or to satisfy a need--comes from within individuals, but hospital pharmacy managers can facilitate motivation by structuring the work environment so that it satisfies employees' needs. Concepts from several theories of motivation are discussed, including McGregor's theory X and theory Y assumptions, Maslow's hierarchy of needs theory, Herzberg's motivation hygiene theory, and Massey's value system theory. Concepts from the Japanese style of management that can be used to facilitate motivation, such as quality circles, also are described. The autocratic, participative, and laissez faire styles of leadership are discussed in the context of the motivation theories, and suggested applications of theoretical concepts to practice are presented.

  5. Noble gas composition of subcontinental lithospheric mantle: An extensively degassed reservoir beneath Southern Patagonia

    Patagonia, in the Southern Andes, is one of the few locations where interactions between the oceanic and continental lithosphere can be studied due to subduction of an active spreading ridge beneath the continent. In order to characterize the noble gas composition of Patagonian subcontinental lithospheric mantle (SCLM), we present the first noble gas data alongside new lithophile (Sr-Nd-Pb) isotopic data for mantle xenoliths from Pali-Aike Volcanic Field and Gobernador Gregores, Southern Patagonia. Based on noble gas isotopic compositions, Pali-Aike mantle xenoliths represent intrinsic SCLM with higher (U + Th + K)/(3He, 22Ne, 36Ar) ratios than the mid-ocean ridge basalt (MORB) source. This reservoir shows slightly radiogenic helium (3He/4He = 6.84-6.90 RA), coupled with a strongly nucleogenic neon signature (mantle source 21Ne/22Ne = 0.085-0.094). The 40Ar/36Ar ratios vary from a near-atmospheric ratio of 510 up to 17700, with mantle source 40Ar/36Ar between 31100-6800+9400 and 54000-9600+14200. In addition, the 3He/22Ne ratios for the local SCLM endmember, at 12.03 ± 0.15 to 13.66 ± 0.37, are higher than depleted MORBs, at 3He/22Ne = 8.31-9.75. Although asthenospheric mantle upwelling through the Patagonian slab window would result in a MORB-like metasomatism after collision of the South Chile Ridge with the Chile trench ca. 14 Ma, this mantle reservoir could have remained unhomogenized after rapid passage and northward migration of the Chile Triple Junction. The mantle endmember xenon isotopic ratios of Pali-Aike mantle xenoliths, which is first defined for any SCLM-derived samples, show values indistinguishable from the MORB source (129Xe/132Xe =1.0833-0.0053+0.0216 and 136Xe/132Xe =0.3761-0.0034+0.0246). The noble gas component observed in Gobernador Gregores mantle xenoliths is characterized by isotopic compositions in the MORB range in terms of helium (3He/4He = 7.17-7.37 RA), but with slightly nucleogenic neon (mantle source 21Ne/22Ne = 0.065-0.079).

  6. Exploration for geothermal resources in the Capital District of New York. Volume 1. Final report

    1981-11-01

    Water chemistry, gas analyses, and geophysical methods including gravity and magnetic surveys, microseismic monitoring, and temperature gradient measurements were used in the Capital District area to evaluate the potential for a hydrothermal geothermal system. Water and gas chemistries provided indirect indicators, and temperature gradients provided direct indications of a geothermal system. Gravity results were supportive of gradient and chemistry data, but seismic and magnetic work have thus far provided little information on the potential system. Gradients throughout the area ranged from an average background value of about 10/sup 0/C/km to a high of roughly 44/sup 0/C/km. The highest gradient values, the most unusual water chemistries and largest carbon dioxide exhalations occur along the Saratoga and McGregor faults between Saratoga Springs and Schenectady, and indicate a good potential for a usable hydrothermal geothermal system at depth.

    Full Text Available Gregor A., Špajdel M.: Romantic love from a social neuroscience perspective In our work we describe romantic love in terms of cerebral activity and define its specific anatomic correlates. We also offer a sum of current knowledge coming out from the previous research in social neuroscience and provide a picture of how is brain activity connected with psychological processes. Analysis of gathered data shows Chat romantic love activates not only subcortical regions, which mediates a variety of emotions involved in motivation and reward-seeking, but also activates higher cerebral areas involved in social cognition, attention, memory, mental association, and self-representation. Romantic love has its strongest base in ventral tegmental area and caudate nucleus, which are the primar regions of infatuation respectively. Other regions such as cingular cortex, posterior hippocamus, and hypothalamus deal with attachment bond, sexual desire, and inclusion of other in the Self.

  9. The effect of pre spring spray to reduce of citrus important pests.

    The importance of pre spring spray against citrus aphids, Pulvinaria aurantii Cockerell and Panonychus citri McGregor that are the most important pest of citrus during spring was tested. In this research, 150 trees ten years old sweet orange (Thomson navel on Citrus aurantium (root stocks)) in a citrus orchard approximately three hectares sampled. The experiment was laid out in a totally randomized (one-way) design replicated five times. According to the results, the pre spring spray do not effect on population density of citrus aphids and P. aurantii during March, April, May and June. However, the P. citri population decreased. Therefore, it seems the pre spring spray in citrus orchards is not necessary, but if P. citri is observed, the pre spring spray should be recommended.

  10. The Human Genoma

    Groot de Restrepo Helena

    2002-01-01

    The process to decipher the genetic code has taken several years and it began with the investigations that he carried out toward half of the XIX century the Czech monk Gregor Mendel who used characteristic contrasting in the plants to study the laws of the inheritance. He made two surprising discoveries. First that many characteristics are inherited in a form of everything or anything: a plant is high or short, and their seeds are flat or rough and second that disappears during a generation when crossing those plants to each other one of the characteristic. When crossing a short plant with a discharge, in the first generation, high plants will only be obtained, but when crossing them again, the characteristic that didn't show during a generation, the short plant will appear again. The article is about the genes and chromosomes, mutations and like the genes work among other topics

  11. From Mendel's discovery on pea to today's plant genetics and breeding : Commemorating the 150th anniversary of the reading of Mendel's discovery.

    This work discusses several selected topics of plant genetics and breeding in relation to the 150th anniversary of the seminal work of Gregor Johann Mendel. In 2015, we celebrated the 150th anniversary of the presentation of the seminal work of Gregor Johann Mendel. While Darwin's theory of evolution was based on differential survival and differential reproductive success, Mendel's theory of heredity relies on equality and stability throughout all stages of the life cycle. Darwin's concepts were continuous variation and "soft" heredity; Mendel espoused discontinuous variation and "hard" heredity. Thus, the combination of Mendelian genetics with Darwin's theory of natural selection was the process that resulted in the modern synthesis of evolutionary biology. Although biology, genetics, and genomics have been revolutionized in recent years, modern genetics will forever rely on simple principles founded on pea breeding using seven single gene characters. Purposeful use of mutants to study gene function is one of the essential tools of modern genetics. Today, over 100 plant species genomes have been sequenced. Mapping populations and their use in segregation of molecular markers and marker-trait association to map and isolate genes, were developed on the basis of Mendel's work. Genome-wide or genomic selection is a recent approach for the development of improved breeding lines. The analysis of complex traits has been enhanced by high-throughput phenotyping and developments in statistical and modeling methods for the analysis of phenotypic data. Introgression of novel alleles from landraces and wild relatives widens genetic diversity and improves traits; transgenic methodologies allow for the introduction of novel genes from diverse sources, and gene editing approaches offer possibilities to manipulate gene in a precise manner.

  12. Seeds of doubt: Mendel's choice of Hieracium to study inheritance, a case of right plant, wrong trait.

    Bicknell, Ross; Catanach, Andrew; Hand, Melanie; Koltunow, Anna

    2016-12-01

    In this review, we explore Gregor Mendel's hybridization experiments with Hieracium , update current knowledge on apomictic reproduction and describe approaches now being used to develop true-breeding hybrid crops. From our perspective, it is easy to conclude that Gregor Mendel's work on pea was insightful, but his peers clearly did not regard it as being either very convincing or of much importance. One apparent criticism was that his findings only applied to pea. We know from a letter he wrote to Carl von Nägeli, a leading botanist, that he believed he needed to "verify, with other plants, the results obtained with Pisum". For this purpose, Mendel adopted Hieracium subgenus Pilosella, a phenotypically diverse taxon under botanical study at the time. What Mendel could not have known, however, is that the majority of these plants are not sexual plants like pea, but instead are facultatively apomictic. In these forms, the majority of seed arises asexually, and such progeny are, therefore, clones of the maternal parent. Mendel obtained very few hybrids in his Hieracium crosses, yet we calculate that he probably emasculated in excess of 5000 Hieracium florets to even obtain the numbers he did. Despite that effort, he was perplexed by the results, and they ultimately led him to conclude that "the hybrids of Hieracium show a behaviour exactly opposite to those of Pisum". Apomixis is now a topic of intense research interest, and in an ironic twist of history, Hieracium subgenus Pilosella has been developed as a molecular model to study this trait. In this paper, we explore further Mendel's hybridization experiments with Hieracium, update current knowledge on apomictic reproduction and describe approaches now being used to develop true-breeding hybrid crops.

  13. Calculating the Ionization Constant of Functional Groups of Carboxyl Ion Exchangers

    The potentiometric titration of a weakly basic carboxyl cation exchanger, obtained via alkaline hydrolysis of an acrylonitrile copolymer with divinyl benzene (degree of crosslinking, 12%) in a wide range of variation in a solution of pH (2-12) and NaCl (concentration 0.01, 0.1, 0.5, 1 M), is considered. The maximum ion-exchange capacity of the ion exchanger for Na+ is determined (10.10 ± 0.088 mmol/g of the dry mass) and found to be independent of the solution's ionic strength. It is established that in the investigated range of NaCl concentrations and pH, the acid-base balance is adequately described by Gregor's equation. The parameters of this equation are calculated as a function of the NaCl concentration: p K a = 8.13 ± 0.04, n = 1.50 ± 0.02 for 0.01 M; p K a = 6.56 ± 0.04, n = 2.60 ± 0.07 for 0.1 M; and p K a = 5.66 ± 0.6, n = 2.62 ± 0.06 for 0.5 and 1 M. It is shown that to describe the acid-base balance correctly within the proposed model we must estimate the adequacy of the experimental and calculated values of the ion exchanger's capacity at each pH value according to the calculated parameters of Gregor's equation.

  14. High-resolution imaging and near-infrared spectroscopy of penumbral decay

    Aims: Combining high-resolution spectropolarimetric and imaging data is key to understanding the decay process of sunspots as it allows us to scrutinize the velocity and magnetic fields of sunspots and their surroundings. Methods: Active region NOAA 12597 was observed on 2016 September 24 with the 1.5-meter GREGOR solar telescope using high-spatial-resolution imaging as well as imaging spectroscopy and near-infrared (NIR) spectropolarimetry. Horizontal proper motions were estimated with local correlation tracking, whereas line-of-sight (LOS) velocities were computed with spectral line fitting methods. The magnetic field properties were inferred with the "Stokes Inversions based on Response functions" (SIR) code for the Si I and Ca I NIR lines. Results: At the time of the GREGOR observations, the leading sunspot had two light bridges indicating the onset of its decay. One of the light bridges disappeared, and an elongated, dark umbral core at its edge appeared in a decaying penumbral sector facing the newly emerging flux. The flow and magnetic field properties of this penumbral sector exhibited weak Evershed flow, moat flow, and horizontal magnetic field. The penumbral gap adjacent to the elongated umbral core and the penumbra in that penumbral sector displayed LOS velocities similar to granulation. The separating polarities of a new flux system interacted with the leading and central part of the already established active region. As a consequence, the leading spot rotated 55° clockwise over 12 h. Conclusions: In the high-resolution observations of a decaying sunspot, the penumbral filaments facing the flux emergence site contained a darkened area resembling an umbral core filled with umbral dots. This umbral core had velocity and magnetic field properties similar to the sunspot umbra. This implies that the horizontal magnetic fields in the decaying penumbra became vertical as observed in flare-induced rapid penumbral decay, but on a very different time-scale.

    Full Text Available Recientemente comunicamos lesiones graves en el glomus carotídeo y los ganglios autonómicos de ratas SHR y sugerimos que este efecto se debía más al aumento de la presión arterial que al envejecimiento. Posteriormente demostramos, en SHR, que el ramipril, en comparación con el atenolol, ejerce un efecto protector sobre estas estructuras más allá de la reducción de la presión arterial. Teniendo en cuenta que no existen trabajos que describan los cambios que origina el bloqueo AT1 sobre la morfología del glomus en ratas normotensas, se realizó el presente estudio con el objetivo de evaluar el efecto del losartán sobre esta estructura de ratas Wistar macho tratadas durante 8 meses. Se emplearon 14 ratas de 4 semanas de edad, divididas en grupos control y losartán (10 mg/ kg/día en el agua de bebida. La presión sistólica (PAS se registró al inicio y luego mensualmente. A la edad de 9 meses se sacrificaron las ratas y se extrajeron los glomus carotídeos, se tiñeron con hematoxilina-eosina y tricrómico de Masson y se procesaron para histomorfometría con un analizador de imágenes. El grupo control registró una PAS de 115 ± 8,1, mientras que en el grupo losartán fue de 105 ± 8,3 mm Hg (p = 0,0375. Histomorfométricamente, el grupo tratado mostró un área mayor del glomus con respecto al control (497.931 ± 48.783 versus 59.668 ± 6.196 µm2; p < 0,0001 y una relación pared/luz en las arteriolas glómicas de 0,7 ± 0,1 versus 2,7 ± 0,6, respectivamente (p < 0,0001. El grupo control mostró disminución del área glómica y un aumento de la relación pared/luz, lo cual sugiere que la atrofia de las estructuras estudiadas a través del aumento de la edad se vincula con el aporte nutricio arterial.

    Full Text Available La esclerodermia lineal (EL es una forma localizada de la enfermedad, caracterizada por la proliferación fibroblástica y los infiltrados linfocitarios perivasculares en la dermis. En los estadios terminales de la enfermedad, hay depósito de colágeno en exceso con atrofia cutánea y de los anexos, todo lo cual sugiere una alteración de la regulación de la función fibroblástica, con participación de los factores de crecimiento en la patogenia de la enfermedad. Este trabajo se planeó para examinar la expresión de los factores TGF-ß y PDFG en biopsias de piel de pacientes con EL y de controles sanos, con estudio inmunohistoquímico. Para idenficar el TGFß se emplearon dos anticuerpos policlonales TGF-ß1 (RaB4 y TGF-ß2 (CL-B1/29 y dos anticuerpos monoclonales para identificar el PDFG: PDFG-AA (3E-205 y PDFG-BB (1F-133.

La tinción para PDGF-AA y PDGF-BB fue intensa en las células endoteliales y en las glándulas sudoríparas en la EL y en la piel normal. El infiltrado linfocitario y los haces colágenos anormales no se tiñeron para TGF- ? ni para PDGF. La intensidad y la extensión de la reactividad evaluada en los tejidos con una escala de 0 (ausencia de tinción a 4 (tinción notoria indican que la expresión de TGF-ß1, TGFß2, PDGF-AA y PDGF-BB son similares en la EL y en la piel normal. Nuestros hallazgos no apoyan la hipótesis según la cual la actividad fibroblástica excesiva y el depósito de colágeno anormal observados en la esclerodermia lineal estén asociados con alteraciones de la regulación del TGF-ß o del PDGF.

    Full Text Available Vários estudos destacam as espécies reativas de oxigênio e nitrogênio (ERONs como importantes contribuintes na patogênese de numerosas doenças cardiovasculares, incluindo hipertensão, aterosclerose e falência cardíaca. Tais espécies são moléculas altamente bioativas e com vida curta derivadas, principalmente, da redução do oxigênio molecular. O complexo enzimático da NADPH oxidase é a maior fonte dessas espécies reativas na vasculatura. Sob condições fisiológicas, a formação e eliminação destas substâncias aparecem balanceadas na parede vascular. Durante o desbalanço redox, entretanto, há um aumento na atividade da NADPH oxidase e predomínio de agentes pró-oxidantes, superando a capacidade de defesa orgânica antioxidante. Além disso, tal hiperatividade enzimática reduz a biodisponibilidade do óxido nítrico, crucial para a vasodilatação e a manutenção da função vascular normal. Apesar de a NADPH oxidase relacionar-se diretamente à disfunção endotelial, foi primeiramente descrita por sua expressão em fagócitos, onde sua atividade determina a eficácia dos mecanismos de defesa orgânica contra patógenos. As sutis diferenças existentes entre as unidades estruturais das NADPH oxidases, a depender do tipo celular que as expressa, podem ter implicações terapêuticas, permitindo a inibição seletiva do desequilíbrio redox induzido pela NADPH oxidase, sem comprometer, entretanto, sua participação nas vias fisiológicas de sinalização celular que garantem a proteção contra microorganismos.Varios estudios destacan las especies reactivas de oxígeno y nitrógeno (ERON como importantes contribuyentes en la patogénesis de numerosas enfermedades cardiovasculares, incluyendo hipertensión, aterosclerosis y falla cardíaca.

    Full Text Available Mette Mogensen1, Gregor BE Jemec21Department of Dermatology, Gentofte Hospital, Hellerup, Denmark; 2Department of Dermatology, Roskilde Hospital, Health Sciences Faculty, University of Copenhagen, Roskilde, DenmarkIntroduction: In 2009, the WHO listed ultraviolet (UV radiation as a group 1 carcinogen. In spite of this, each year, millions of people tan indoor in Western countries. The aim of this review is to summarize evidence of tanning bed carcinogenesis and to present guidelines for use of tanning beds and patient safety advice.Methods: A narrative review of the literature was conducted based on both PubMed and Medline searches and on literature review of the retrieved papers.Results: Use of indoor tanning beds represents a significant and avoidable risk factor for the development of both melanoma and nonmelanoma skin cancers. Frequent tanners are more often adolescent females. Tanning beds have additional potential adverse effects such as burns, solar skin damage, infection, and possibly also addictive behavior.Discussion: The effort in preventing UV light-induced carcinogenesis should currently be aimed at developing new strategies for public health information. Tanning beds are one preventable source of UV radiation. In the majority of people solar UV radiation continues to be the major factor and therefore anti-tanning campaigns must always include sunbathers.Keywords: tanning beds, skin cancers, melanoma, nonmelanoma

  4. A MODEL OF MAGNETIC BRAKING OF SOLAR ROTATION THAT SATISFIES OBSERVATIONAL CONSTRAINTS

    Denissenkov, Pavel A.

    2010-01-01

    The model of magnetic braking of solar rotation considered by Charbonneau and MacGregor has been modified so that it is able to reproduce for the first time the rotational evolution of both the fastest and slowest rotators among solar-type stars in open clusters of different ages, without coming into conflict with other observational constraints, such as the time evolution of the atmospheric Li abundance in solar twins and the thinness of the solar tachocline. This new model assumes that rotation-driven turbulent diffusion, which is thought to amplify the viscosity and magnetic diffusivity in stellar radiative zones, is strongly anisotropic with the horizontal components of the transport coefficients strongly dominating over those in the vertical direction. Also taken into account is the poloidal field decay that helps to confine the width of the tachocline at the solar age. The model's properties are investigated by numerically solving the azimuthal components of the coupled momentum and magnetic induction equations in two dimensions using a finite element method.

    Full Text Available Recent German-language films frame anti-establishment activities as a rejuvenating force. In Die fetten Jahre sind vorbei (2004 and Was tun, wenn’s brennt? (2001, the young filmmakers Hans Weingartner and Gregor Schnitzler take a nostalgic approach to the tradition of protest in Germany. Volker Schlöndorff, in contrast, builds on first-hand memories of the 1970s and the RAF, depicting the escalation of violence in Die Stille nach dem Schuß (2000. This paper explores the ways in which the three films foreground personal motivations, rather than political causes, arguing that friendship is used to gauge the success of protest. While the friends in Die fetten Jahre and Was tun? are (reunited through their activism, the terrorist plots portrayed in Stille lead to the protagonist’s isolation and untimely death. Ultimately, Schlöndorff places German history at the center of the tragic plotline, whereas the younger filmmakers take a position of ironic distance vis-à-vis the past. By placing a strong emphasis on community, these three films indicate that reunification and globalization give rise to dreams of friendship and protest in post-Wall Berlin.

  6. The role of Effective Supervision on academic performance of Senior High Schools in Ghana

    Full Text Available In all facets of life, supervision has become a cross-cutting edge tool and a pivot around which performance revolves. There are widespread and on-going debates centred on the influence of effective supervision on academic performance in our academic institutions. This study examined the role of supervision on academic performance in Senior High Schools (SHS in Ghana. The study was based on the collegial model of educational management and the supervision model, Theory Y as proposed by Douglas McGregor. This study employed the descriptive research survey design. Through a questionnaire, data analysed was collected from 963 respondents who were purposively selected from randomised schools in each region comprising of headmasters, their assistants and heads of department of 155 SHSs across Ghana. The WAEC results (2006-2009 and 2011 of the sampled schools were analysed. Reliability coefficient of the questionnaire was Cronbach’s alpha (α = 0.826. The Statistical Product and Service Solutions (SPSS version 18 software was employed in the analyses of data using, mean, standard deviation, correlation and independent t-test. The study revealed that there was a positive weak significant relationship between supervision roles of heads and academic performance of students. Moreso, there was a positive weak significant relationship between gender of heads and their supervision roles. The study recommended that supervision should be intensified in SHS. Heads of SHS should be re-orientated in the new trends of supervision in schools.

  7. Mendel in the kitchen a scientist's view of genetically modified foods

    Fedoroff, Nina V

    2004-01-01

    While European restaurants race to footnote menus, reassuring concerned gourmands that no genetically modified ingredients were used in the preparation of their food, starving populations around the world eagerly await the next harvest of scientifically improved crops. "Mendel in the Kitchen" provides a clear and balanced picture of this tangled, tricky (and very timely) topic. Any farmer you talk to, could tell you that we've been playing with the genetic makeup of our food for millennia, carefully coaxing nature to do our bidding. The practice officially dates back to Gregor Mendel - who was not a renowned scientist, but a 19th century Augustinian monk. Mendel spent many hours toiling in his garden, testing and cultivating more than 28,000 pea plants, selectively determining very specific characteristics of the peas that were produced, ultimately giving birth to the idea of heredity - and the now very common practice of artificially modifying our food. But as science takes the helm, steering common field pr...

  8. Newton’s apple and other myths about science

    Kampourakis, Kostas

    2015-01-01

    A falling apple inspired Isaac Newton’s insight into the law of gravity—or so the story goes. Is it true? Perhaps not. But the more intriguing question is why such stories endure as explanations of how science happens. Newton’s Apple and Other Myths about Science brushes away popular misconceptions to provide a clearer picture of great scientific breakthroughs from ancient times to the present. Among the myths refuted in this volume is the idea that no science was done in the Dark Ages, that alchemy and astrology were purely superstitious pursuits, that fear of public reaction alone led Darwin to delay publishing his theory of evolution, and that Gregor Mendel was far ahead of his time as a pioneer of genetics. Several twentieth-century myths about particle physics, Einstein’s theory of relativity, and more are discredited here as well. In addition, a number of broad generalizations about science go under the microscope of history: the notion that religion impeded science, that scientists typically a...

  9. Ontogenetic shifts in intraguild predation on thrips by phytoseiid mites: the relevance of body size and diet specialization.

    Walzer, A; Paulus, H F; Schausberger, P

    2004-12-01

    In greenhouse agroecosystems, a guild of spider mite predators may consist of the oligophagous predatory mite Phytoseiulus persimilis Athias-Henriot, the polyphagous predatory mite Neoseiulus californicus McGregor (both Acari: Phytoseiidae) and the primarily herbivorous but facultatively predatory western flower thrips Frankliniella occidentalis Pergande (Thysanoptera: Thripidae). Diet-specialization and the predator body size relative to prey are crucial factors in predation on F. occidentalis by P. persimilis and N. californicus. Here, it was tested whether the relevance of these factors changes during predator ontogeny. First, the predator (protonymphs and adult females of P. persimilis and N. californicus): prey (F. occidentalis first instars) body size ratios were measured. Second, the aggressiveness of P. persimilis and N. californicus towards F. occidentalis was assessed. Third, survival, development and oviposition of P. persimilis and N. californicus with F. occidentalis prey was determined. The body size ranking was P. persimilis females > N. californicus females > P. persimilis protonymphs > N. californicus protonymphs. Neoseiulus californicus females were the most aggressive predators, followed by highly aggressive N. californicus protonymphs and moderately aggressive P. persimilis protonymphs. Phytoseiulus persimilis females did not attack thrips. Frankliniella occidentalis larvae are an alternative prey for juvenile N. californicus and P. persimilis, enabling them to reach adulthood. Females of N. californicus but not P. persimilis sustained egg production with thrips prey. Within the guild studied here, N. californicus females are the most harmful predators for F. occidentalis larvae, followed by N. californicus and P. persimilis juveniles. Phytoseiulus persimilis females are harmless to F. occidentalis.

  10. Diurnal temperature variations affect development of a herbivorous arthropod pest and its predators.

    Full Text Available The impact of daily temperature variations on arthropod life history remains woefully understudied compared to the large body of research that has been carried out on the effects of constant temperatures. However, diurnal varying temperature regimes more commonly represent the environment in which most organisms thrive. Such varying temperature regimes have been demonstrated to substantially affect development and reproduction of ectothermic organisms, generally in accordance with Jensen's inequality. In the present study we evaluated the impact of temperature alternations at 4 amplitudes (DTR0, +5, +10 and +15°C on the developmental rate of the predatory mites Phytoseiulus persimilis Athias-Henriot and Neoseiulus californicus McGregor (Acari: Phytoseiidae and their natural prey, the two-spotted spider mite Tetranychus urticae Koch (Acari: Tetranychidae. We have modelled their developmental rates as a function of temperature using both linear and nonlinear models. Diurnally alternating temperatures resulted in a faster development in the lower temperature range as compared to their corresponding mean constant temperatures, whereas the opposite was observed in the higher temperature range. Our results indicate that Jensen's inequality does not suffice to fully explain the differences in developmental rates at constant and alternating temperatures, suggesting additional physiological responses play a role. It is concluded that diurnal temperature range should not be ignored and should be incorporated in predictive models on the phenology of arthropod pests and their natural enemies and their performance in biological control programmes.

    Humidity-controlled cold storage, in which the water vapour pressure is saturated, can prolong the survival of the predatory mites Neoseiulus californicus (McGregor) and Phytoseiulus persimilis Athias-Henriot (Acari: Phytoseiidae). However, information on the optimum air temperature for long-term storage by this method is limited. The authors evaluated the survival of mated adult females of N. californicus and P. persimilis at 5.0, 7.5, 10.0 and 12.5 °C under saturated water vapour condition (vapour pressure deficit 0.0 kPa). N. californicus showed a longer survival time than P. persimilis at all the air temperatures. The longest mean survival time of N. californicus was 11 weeks at 7.5 °C, whereas that of P. persimilis was 8 weeks at 5.0 °C. After storage at 7.5 °C for 8 weeks, no negative effect on post-storage oviposition was observed in N. californicus, whereas the oviposition of P. persimilis stored at 5.0 °C for 8 weeks was significantly reduced. The interspecific variation in the response of these predators to low air temperature might be attributed to their natural habitat and energy requirements. These results may be useful for the long-term storage of these predators, which is required for cost-effective biological control. © 2013 Society of Chemical Industry.

  13. Evaluation of predatory mites and Acramite for control of twospotted spider mites in strawberries in north central Florida.

    Rhodes, Elena M; Liburd, Oscar E

    2006-08-01

    Greenhouse and field experiments were conducted from 2003 to 2005 to determine the effectiveness of two predatory mite species, Phytoseiulus persimilis Athias-Henriot and Neoseiulus californicus (McGregor), and a reduced-risk miticide, Acramite 50 WP (bifenazate), for control of twospotted spider mite, Tetranychus urticae Koch, in strawberries (Fragaria x ananassa Duchesne). In greenhouse tests, three treatments consisting of releases of P. persimilis, N. californicus, and an untreated control were evaluated. Both species of predatory mites significantly reduced twospotted spider mite numbers below those found in the control during the first 3 wk of evaluation. However, during week 4, twospotted spider mite numbers on the plants treated with P. persimilis increased and did not differ significantly from the control. Field studies used releases of P. persimilis and N. californicus, applications of Acramite, and untreated control plots. Both N. californicus and P. persimilis significantly reduced populations of twospotted spider mite below numbers recorded in the control plots. During the 2003-2004 field season P. persimilis took longer than N. californicus to bring the twospotted spider mite population under control (< 10 mites per leaflet). Acramite was effective in reducing twospotted spider mite populations below 10 mites per leaflet during the 2003-2004 field season but not during the 2004-2005 field season, possibly because of a late application. These findings indicate that N. californicus releases and properly timed Acramite applications are promising options for twospotted spider mite control in strawberries for growers in north Florida and other areas of the southeast.

    Greenhouse and field experiments were conducted from 2003 to 2005 to determine the effectiveness of combining releases of two predatory mite species, Phytoseiulus persimilis Athias-Henriot and Neoseiulus californicus (McGregor), and a reduced-risk miticide, Acramite (bifenazate), for control of twospotted spider mite (TSSM) (Tetranychus urticae Koch) in strawberries. In the greenhouse experiment, a combination treatment of P. persimilis and N. californicus was compared with single treatments of each species, Acramite application, and untreated control. All treatments significantly reduced TSSM numbers compared with the control. Field studies employed two approaches: one investigating the same five treatments as the greenhouse experiment and a second, comparing combination treatments of P. persimilis/N. californicus, Acramite/N. californicus, and Acramite/P. persimilis to single treatments of each and to control plots. Among the combination treatments, the P. persimilis/N. californicus treatment significantly reduced TSSM numbers compared with the control, but was not as effective as N. californicus alone during the 2003-2004 field season. Also, combination treatments of Acramite/N. californicus, and Acramite/P. persimilis significantly reduced TSSM populations compared with the control. These findings indicate that all three combination treatments are promising options for TSSM control in strawberries for growers in northern Florida and other strawberry producing areas of the world.

  15. From Mendel to epigenetics: History of genetics.

    Gayon, Jean

    2016-01-01

    The origins of genetics are to be found in Gregor Mendel's memoir on plant hybridization (1865). However, the word 'genetics' was only coined in 1906, to designate the new science of heredity. Founded upon the Mendelian method for analyzing the products of crosses, this science is distinguished by its explicit purpose of being a general 'science of heredity', and by the introduction of totally new biological concepts (in particular those of gene, genotype, and phenotype). In the 1910s, Mendelian genetics fused with the chromosomal theory of inheritance, giving rise to what is still called 'classical genetics'. Within this framework, the gene is simultaneously a unit of function and transmission, a unit of recombination, and of mutation. Until the early 1950s, these concepts of the gene coincided. But when DNA was found to be the material basis of inheritance, this congruence dissolved. Then began the venture of molecular biology, which has never stopped revealing the complexity of the way in which hereditary material functions. Copyright © 2016 Académie des sciences.

  17. Study strategies and beliefs about learning as a function of academic achievement and achievement goals.

    2018-05-01

    Prior research by Hartwig and Dunlosky [(2012). Study strategies of college students: Are self-testing and scheduling related to achievement? Psychonomic Bulletin & Review, 19(1), 126-134] has demonstrated that beliefs about learning and study strategies endorsed by students are related to academic achievement: higher performing students tend to choose more effective study strategies and are more aware of the benefits of self-testing. We examined whether students' achievement goals, independent of academic achievement, predicted beliefs about learning and endorsement of study strategies. We administered Hartwig and Dunlosky's survey, along with the Achievement Goals Questionnaire [Elliot, A. J., & McGregor, H. A. (2001). A 2 × 2 achievement goal framework. Journal of Personality & Social Psychology, 80, 501-519] to a large undergraduate biology course. Similar to results by Hartwig and Dunlosky, we found that high-performing students (relative to low-performing students) were more likely to endorse self-testing, less likely to cram, and more likely to plan a study schedule ahead of time. Independent of achievement, however, achievement goals were stronger predictors of certain study behaviours. In particular, avoidance goals (e.g., fear of failure) coincided with increased use of cramming and the tendency to be driven by impending deadlines. Results suggest that individual differences in student achievement, as well as the underlying reasons for achievement, are important predictors of students' approaches to studying.

  18. An Ecoinformatics Approach to Field-Scale Evaluation of Insecticide Effects in California Citrus: Are Citrus Thrips and Citrus Red Mite Induced Pests?

    2018-05-28

    Experimental approaches to studying the consequences of pesticide use, including impacts on beneficial insects, are vital; however, they can be limited in scale and realism. We show that an ecoinformatics approach that leverages existing data on pesticides, pests, and beneficials across multiple fields can provide complementary insights. We do this using a multi-year dataset (2002-2013) on pesticide applications and density estimates of two pests, citrus thrips (Scirtothrips citri (Moulton [Thysanoptera: Thripidae])) and citrus red mites (Panonychus citri McGregor [Acari: Tetranychidae]), and a natural enemy (Euseius spp. predatory mites) collected from citrus groves in the San Joaquin Valley of California. Using correlative analyses, we investigated the long-term consequences of pesticide use on S. citri and P. citri population densities to evaluate the hypothesis that the pest status of these species is largely due to the disruption of natural biological control-i.e., these are induced pests. We also evaluated short-term pesticide efficacy (suppression of citrus thrips and citrus red mite populations immediately post-application) and asked if it was correlated with the suppression of Euseius predator populations. Although the short-term efficacy of different pesticides varied significantly, our dataset does not suggest that the use of citrus pesticides suppressed Euseius densities or worsened pest problems. We also find that there is no general trade-off between pesticide efficacy and pesticide risk to Eusieus, such that highly effective and minimally disruptive compounds were available to citrus growers during the studied time period.

  19. [Research progress on the cloning of Mendel's gene in pea (Pisum sativum L.) and its application in genetics teaching].

    He, Feng-Hua; Zhu, Bi-Yan; Gao, Feng; Li, Shao-Shan; Li, Niang-Hui

    2013-07-01

    One hundred and fifty years ago, Gregor Mendel investigated the segregation of seven traits in pea (Pisum sativum) and established the law of segregation and the law of independent assortment in genetics. After the two laws of genetics were rediscovered in 1900, the seven traits have been extensively investigated in the fields of plant physiology and biochemistry as well as in the cell and molecular levels. Recently, with the development of molecular technology in genetics, four genes for seed shape (R), stem length (Le), cotyledon colour (I), and flower colour (A) have been cloned and sequenced; and another three genes for immature pod colour (Gp), fasciation (Fa) and pod form (V) have been located in the linkage groups, respectively. The identification and cloning of the four Mendel's genes will help deeply understand the basic concept of gene in many respects: like the diversity of gene function, the different origins for gene mutation in molecular level, and the molecular nature of a dominant gene or a recessive gene. In teaching of genetics, the introduction of most recent research advancements of cloning of Mendel's genes to the students and the interpretation of the Mendel's laws in molecular level will help students promote their learning interests in genetics and help students grasp the whole content from classical genetics to molecular genetics and the developmental direction of this subject.

    van Dijk, Peter J; Ellis, T H Noel

    2016-12-01

    Gregor Mendel's "Experiments on Plant Hybrids" (1865/1866), published 150 years ago, is without doubt one of the most brilliant works in biology. Curiously, Mendel's later studies on Hieracium (hawkweed) are usually seen as a frustrating failure, because it is assumed that they were intended to confirm the segregation ratios he found in Pisum Had this been his intention, such a confirmation would have failed, since, unknown to Mendel, Hieracium species mostly reproduce by means of clonal seeds (apomixis). Here we show that this assumption arises from a misunderstanding that could be explained by a missing page in Mendel's first letter to Carl Nägeli. Mendel's writings clearly indicate his interest in "constant hybrids," hybrids which do not segregate, and which were "essentially different" from "variable hybrids" such as in Pisum After the Pisum studies, Mendel worked mainly on Hieracium for 7 years where he found constant hybrids and some great surprises. He also continued to explore variable hybrids; both variable and constant hybrids were of interest to Mendel with respect to inheritance and to species evolution. Mendel considered that their similarities and differences might provide deep insights and that their differing behaviors were "individual manifestations of a higher more fundamental law."

    Full Text Available The author explores the central importance of death in Bakhtin’s carnival and notes that death is joyfully accepted as it gets rid of the old and makes space for the new. Death for Bakhtin is “life’s regeneration”. But in many societies both simple and sophisticated this is not the case. Here we deal with a sacrificial logic where death is feared and displaced onto a sacrificial victim who is killed for the benefit of the majority. Although we like to think of modern society as being beyond sacrifice we see it in many cultural formations. The author uses anthropology as an interpretive key to explain the story of Franz Kafka’s Metamorphosis. Indeed the Metamorphosis reads like a purificatory rite in which one member of the social group (a family becomes a monster (the insect, literally and is slowly but systematically rejected by the other members of his family. In the end, Gregor the insect/family member who has become a kind of filthy cockroach, dies to save his family from further disgust. His body is disposed of anonymously. At the end of the story we see Gregor’s sister has bloomed into adolescence and so (without doing too much damage to the text we can interpret the story as a kind of spring purification right to discard the bad and the rotten and bring in the good and the fertile.

    Full Text Available Rethinking Darwin? About Ex‐aptations and Neotenies. Concerning Mickey Mouse, Goofy and likeable mexican Salamanders The theory of evolution by natural selection of Charles Darwin, whose first general exposure dates back to 1859, with the publication of the Origin of Species, is still a matter of intense debate among natural sciences’ scholars and philosophers. After the merger of Darwinian evolutionary research program with the theory of heredity of Gregor Mendel, the mathematical form of population genetics and the analysis of paleontological data (Modern Synthesis and the the important contributions of post-Darwinian authors such as S.J. Gould and N. Eldredge we are entering a new era of great discoveries and news. On the one hand, new data from genetics and paleoanthropology, on the other hand the impetuous development of some fields of applied science such as nanobiotechnology, genetic engineering and synthetic biology put us into the need and the urgency to underline, once again, the relevance and the extraordinary heuristic power of Darwinian research program, an even greater urgency since some authors have announced that we would be at a time to access a post-Darwinian and post-evolutionary era in which man as we actually know it is about to disappear.

  4. The role of radiation induced mutations in crop Improvement

    Souframanien, J.

    2017-01-01

    Sudden, heritable changes in the genetic material, DNA, are known as mutations. Selection of naturally occurring mutations in wild, ancestral species helped humans in the domestication and further improvement of today's crop plants. Gregor Mendel in 1865 used several such natural mutants in his experiments with garden pea to formulate the laws of inheritance. The term mutation itself was used for the first time by Hugo de Vries in 1901 in his mutation theory. Plant breeding based on the science of genetics, as practiced over the past 100 years, exploited the available genetic variability in the primary gene pool of crop plants, and sometimes in related species. Primarily, simple selection of desirable offspring and cross breeding were the earlier methods of breeding and this utilized the occurrence of spontaneous mutations. In nature, occurrence of natural variability in the form of spontaneous mutations is extremely low (about 10 -6 ), which can be enhanced several fold (∼10 -3 ) by using ionizing radiations or chemical mutagens

  5. Global impact of induced mutation in plant breeding

    2001-01-01

    Sudden, heritable changes in the genetic material, DNA, are known as mutations. Selection of naturally occurring mutations in wild, ancestral species helped humans in the domestication and further improvement of today's crop plants. Although Charles Darwin was unaware in 1859 of variation and mutations in living organisms, his theory of evolution by natural selection assumed variability. Much later, it was established that mutations are the source of biodiversity, and the driving force for evolution. Gregor Mendel in 1865 also used several mutants in his experiments with garden pea to formulate the laws of inheritance. The term mutation itself was used for the first time by Hugo de Vries in 1901 in his mutation theory. Plant breeding based on the science of genetics, as practiced over the past 100 years, exploited the available genetic variability in the primary gene pool of crop plants, and sometimes in related species. This approach enlarged the yield potential of crops several fold. It also a) improved the stability of yield by incorporating resistance to various biotic and abiotic stresses; b) improved quality of the produce; and c) altered the adaptability of crop species, providing opportunities to grow new crops for food security outside their traditional range. Genetically improved seed (or other planting material) is the most significant input for developing sustainable cropping systems for food security and economic growth. Half of the increased productivity of today's crop plants comes from genetic improvements. The other half is contributed by inputs and management practices

    Applications of remote sensing for biodiversity conservation typically rely on image classifications that do not capture variability within coarse land cover classes. Here, we compare two measures derived from unclassified remotely sensed data, a measure of habitat heterogeneity and a measure of habitat composition, for explaining bird species richness and the spatial distribution of 10 species in a semi-arid landscape of New Mexico. We surveyed bird abundance from 1996 to 1998 at 42 plots located in the McGregor Range of Fort Bliss Army Reserve. Normalized Difference Vegetation Index values of two May 1997 Landsat scenes were the basis for among-pixel habitat heterogeneity (image texture), and we used the raw imagery to decompose each pixel into different habitat components (spectral mixture analysis). We used model averaging to relate measures of avian biodiversity to measures of image texture and spectral mixture analysis fractions. Measures of habitat heterogeneity, particularly angular second moment and standard deviation, provide higher explanatory power for bird species richness and the abundance of most species than measures of habitat composition. Using image texture, alone or in combination with other classified imagery-based approaches, for monitoring statuses and trends in biological diversity can greatly improve conservation efforts and habitat management.

  8. Evolution of Genetic Techniques: Past, Present, and Beyond

    Full Text Available Genetics is the study of heredity, which means the study of genes and factors related to all aspects of genes. The scientific history of genetics began with the works of Gregor Mendel in the mid-19th century. Prior to Mendel, genetics was primarily theoretical whilst, after Mendel, the science of genetics was broadened to include experimental genetics. Developments in all fields of genetics and genetic technology in the first half of the 20th century provided a basis for the later developments. In the second half of the 20th century, the molecular background of genetics has become more understandable. Rapid technological advancements, followed by the completion of Human Genome Project, have contributed a great deal to the knowledge of genetic factors and their impact on human life and diseases. Currently, more than 1800 disease genes have been identified, more than 2000 genetic tests have become available, and in conjunction with this at least 350 biotechnology-based products have been released onto the market. Novel technologies, particularly next generation sequencing, have dramatically accelerated the pace of biological research, while at the same time increasing expectations. In this paper, a brief summary of genetic history with short explanations of most popular genetic techniques is given.

    Objective:To evaluate the acaricidal activity of the essential oil obtained from roots of Derrisfloribunda (D.floribunda) (Miq.) Benth,and its main constituent nerolidol against the Mexican mite Tetranychus mexicanus (T.mexicanus) (McGregor).Methods:The essential oil from the roots of D.floribunda collected in the Amazon region (Brazil) was obtained by hydrodistillation.Its chemical composition was determined by GC-MS analysis.The acaricidal activities of this essential oil and nerolidol,were evaluated by recording the number of dead females (mortality) and eggs (fertility).Results:The essential oil showed sesquiterpenes as major volatile components.Nerolidol,the main component,represented 68.5% of the total composition of the essential oil.D.floribunda essential oil and nerolidol showed acaricidal activity,with LC50 of 9.61 μg/mL air and 9.2 μg/mL air,respectively,over a 72 h period.In addition,both the essential oil and nerolidol significantly reduced the fecundity of T.mexicanus.Contusions:Due to the economic importance of T.mexicanus and the lack of new pesticides,our data are very promising in the search for efficient and safer acaricidal products.Furthermore,this is the first report about the chemical composition and bioactivity of the essential oil of the Amazon plant species D.floribunda.

  10. Suspension of Egg Hatching Caused by High Humidity and Submergence in Spider Mites.

    Ubara, Masashi; Osakabe, Masahiro

    2015-08-01

    We tested the effects of high humidity and submergence on egg hatching of spider mites. In both the high humidity and submergence treatments, many Tetranychus and Panonychus eggs did not hatch until after the hatching peak of the lower humidity or unsubmerged controls. However, after humidity decreased or water was drained, many eggs hatched within 1-3 h. This was observed regardless of when high humidity or submergence treatments were implemented: either immediately after oviposition or immediately before hatching was due. Normal eyespot formation was observed in most eggs in the high humidity and submergence treatments, which indicates that spider mite embryos develop even when eggs are underwater. Therefore, delays in hatching are not caused by delayed embryonic development. A delay in hatching was always observed in Panonychus citri (McGregor) but was more variable in Tetranychus urticae Koch and Tetranychus kanzawai Kishida. The high humidity and submergence treatments affected but did not suppress larval development in these species. In contrast, many Oligonychus eggs died following the high humidity treatments. In Tetranychus and Panonychus spider mites, suspension of egg hatching may mitigate the adverse effects of rainfall. © The Authors 2015.

  12. A word from the DG: A look to the future

    2006-01-01

    The year 2006 has been an eventful one for particle physics in Europe. Here at CERN, the LHC project has progressed steadily towards the goal of a November 2007 start-up. Although difficulties have inevitably been encountered along the way, they have been overcome. There is growing confidence that any future hurdles can also be overcome, and that the tight commissioning schedule can be met. Looking beyond the LHC start-up, the European strategy process initiated by Council in 2005 has been gaining momentum. Following unanimous endorsement of the strategy by Council at a special meeting in Lisbon on 14 July 2006, Europe now has a coherent long-term vision for particle physics research. At the October meeting of Council, a working group was established under the chairmanship of Professor Gregor Herten of Freiburg University to define how the Council should adapt to its new role and obligations, how it should interface with the European Union and other regions, and how its subsidiary committees should be compo...

  13. Test anxiety, perfectionism, goal orientation, and academic performance.

    Eum, KoUn; Rice, Kenneth G

    2011-03-01

    Dimensions of perfectionism and goal orientation have been reported to have differential relationships with test anxiety. However, the degree of inter-relationship between different dimensions of perfectionism, the 2 × 2 model of goal orientations proposed by Elliot and McGregor, cognitive test anxiety, and academic performance indicators is not known. Based on data from 134 university students, we conducted correlation and regression analyses to test associations between adaptive and maladaptive perfectionism, four types of goal orientations, cognitive test anxiety, and two indicators of academic performance: proximal cognitive performance on a word list recall test and distal academic performance in terms of grade point average. Cognitive test anxiety was inversely associated with both performance indicators, and positively associated with maladaptive perfectionism and avoidance goal orientations. Adaptive and maladaptive perfectionism accounted for significant variance in cognitive test anxiety after controlling for approach and avoidance goal orientations. Overall, nearly 50% of the variance in cognitive test anxiety could be attributed to gender, goal orientations, and perfectionism. Results suggested that students who are highly test anxious are likely to be women who endorse avoidance goal orientations and are maladaptively perfectionistic.

  15. Exploring the nature of science through courage and purpose: a case study of Nikolai Vavilov and plant biodiversity.

    Cohen, Joel I; Loskutov, Igor G

    2016-01-01

    Historical biographies facilitate teaching the 'nature of science'. This case study focuses on how Nikolai Vavilov's unrelenting sense of purpose, courage, and charismatic personality was maintained during violent revolutionary change in Russia. The rediscovery of Gregor Mendel's laws of inheritance provided Vavilov with a scientific foundation for crop improvement, this foundation was later bolstered by Vavilov's personal drive to conserve plant biodiversity. As he advanced theories and pragmatic approaches for genetic improvement and conservation of plants, political leaders in Russian came to reject Mendel's principles and eventually Vavilov's work. This rejection occurred because Joseph Stalin was desperate for a quick remedy to the famine and suffering from forced collective agriculture. Vavilov's work continued, modernizing Russian crop research while inspiring other scientists to save seeds stored in the world's first gene bank. Three themes illustrating the nature of science help examine Vavilov's life: explaining natural phenomena, uncompromising human endeavor, and revising scientific knowledge. The case study concludes with four questions to stimulate student inquiry and self-guided research. They also deepen student understanding of Vavilov's personal sacrifices to ensure use and conservation of plant biodiversity.

  17. Large fully retractable telescope enclosures still closable in strong wind

    Bettonvil, Felix C. M.; Hammerschlag, Robert H.; Jägers, Aswin P. L.; Sliepen, Guus

    2008-07-01

    Two prototypes of fully retractable enclosures with diameters of 7 and 9 m have been built for the high-resolution solar telescopes DOT (Dutch Open Telescope) and GREGOR, both located at the Canary Islands. These enclosures protect the instruments for bad weather and are fully open when the telescopes are in operation. The telescopes and enclosures also operate in hard wind. The prototypes are based on tensioned membrane between movable but stiff bows, which fold together to a ring when opened. The height of the ring is small. The prototypes already survived several storms, with often snow and ice, without any damage, including hurricane Delta with wind speeds up to 68 m/s. The enclosures can still be closed and opened with wind speeds of 20 m/s without any problems or restrictions. The DOT successfully demonstrated the open, wind-flushing concept for astronomical telescopes. It is now widely recognized that also large future telescopes benefit from wind-flushing and retractable enclosures. These telescopes require enclosures with diameters of 30 m until roughly 100 m, the largest sizes for the ELTs (Extreme Large Telescopes), which will be built in the near future. We discuss developments and required technology for the realization of these large sizes.

    Hajduskova, Eva; Literak, Ivan; Papousek, Ivo; Costa, Francisco B; Novakova, Marketa; Labruna, Marcelo B; Zdrazilova-Dubska, Lenka

    2016-04-01

    A novel rickettsial sequence in the citrate synthase gltA gene indicating a novel Rickettsia species has been detected in 7 out of 4524 Ixodes ricinus ticks examined within several surveys performed in the Czech Republic from 2005 to 2009. This new Candidatus Rickettsia sp. sequence has been found in 2 nymphs feeding on wild birds (Luscinia megarhynchos and Erithacus rubecula), in a male tick from vegetation, and 4 ticks feeding on a dog (3 males, 1 female tick). Portions of the ompA, ompB, sca4, and htrA genes were not amplifiable in these samples. A maximum likelihood tree of rickettsiae based on comparisons of partial amino acid sequences of citrate synthase and nucleotide sequences of 16S rDNA genes and phylogenetic analysis revealed a basal position of the novel species in the proximity of R. bellii and R. canadensis. The novel species has been named 'Candidatus Rickettsia mendelii' after the founder of genetics, Gregor Mendel. Copyright © 2016 Elsevier GmbH. All rights reserved.

  19. The Development of Genetics in the Light of Thomas Kuhn's Theory of Scientific Revolutions.

    Portin, Petter

    2015-01-01

    The concept of a paradigm is in the key position in Thomas Kuhn's theory of scientific revolutions. A paradigm is the framework within which the results, concepts, hypotheses and theories of scientific research work are understood. According to Kuhn, a paradigm guides the working and efforts of scientists during the time period which he calls the period of normal science. Before long, however, normal science leads to unexplained matters, a situation that then leads the development of the scientific discipline in question to a paradigm shift--a scientific revolution. When a new theory is born, it has either gradually emerged as an extension of the past theory, or the old theory has become a borderline case in the new theory. In the former case, one can speak of a paradigm extension. According to the present author, the development of modern genetics has, until very recent years, been guided by a single paradigm, the Mendelian paradigm which Gregor Mendel launched 150 years ago, and under the guidance of this paradigm the development of genetics has proceeded in a normal fashion in the spirit of logical positivism. Modern discoveries in genetics have, however, created a situation which seems to be leading toward a paradigm shift. The most significant of these discoveries are the findings of adaptive mutations, the phenomenon of transgenerational epigenetic inheritance, and, above all, the present deeply critical state of the concept of the gene.

  20. Achievement goals, competition appraisals, and the psychological and emotional welfare of sport participants.

    Adie, James W; Duda, Joan L; Ntoumanis, Nikos

    2008-06-01

    Grounded in the 2x2 achievement goal framework (Elliot & McGregor, 2001), a model was tested examining the hypothesized relationships between approach and avoidance (mastery and performance) goals, challenge and threat appraisals of sport competition, and positive and negative indices of well-being (i.e., self-esteem, positive, and negative affect). A further aim was to determine the degree to which the cognitive appraisals mediated the relationship between the four achievement goals and the indicators of athletes' welfare. Finally, measurement and structural invariance was tested with respect to gender in the hypothesized model. An alternative model was also estimated specifying self-esteem as an antecedent of the four goals and cognitive appraisals. Four hundred and twenty-four team sport participants (Mage=24.25) responded to a multisection questionnaire. Structural equation modeling analyses provided support for the hypothesized model only. Challenge and threat appraisals partially mediated the relationships observed between mastery-based goals and the well-being indicators. Lastly, the hypothesized model was found to be invariant across gender.

  1. The effect of chronic hyperthyroidism and restored euthyroid state by methimazole therapy in rat small mesenteric arteries.

    2013-02-15

    Not much has been reported about the effects of hyperthyroidism and its correction on resistance vessels, and just two inconsistent studies have investigated the impacts of restored euthyroidism on vascular reactivity. In this regard, we designed the current study to evaluate the vascular reactivity of the mesenteric arteries of hyperthyroid and restore euthyroid rats. Hyperthyroidism was induced by administration of triiodothyronine (T3; 300μg/kg, i.p., for 12 weeks in T3 group). Euthyroidism was restored by administration of T3 for 8 weeks and then T3+Methimazole (0.003% in drinking water) for 4 weeks (T3+MMI group). According to the McGregor method, vascular relaxation and contractility response were measured in response to acetylcholine or phenylephrine respectively. We found that maximal contractility response (Emax) to phenylephrine in the T3 group was significantly decreased (P0.05). In conclusion, synthesis of both nitric oxide (NO) and endothelium-derived hyperpolarizing factor (EDHF) in mesenteric arteries significantly increased as a consequence of hyperthyroidism, and this abnormal vascular reactivity is corrected by methimazole therapy.

  2. Spatial distribution of phytophagous mites (Aca ri: Tetranychidae) on strawberry plants

    Fadini, Marcos A.M.; Venzon, Madelaine; Oliveira, Hamilton G.; Pallini, Angelo; Vilela, Evaldo F.

    2007-01-01

    Many phytophagous mites can attack strawberry plants, Fragaria x ananassa, among them the southern red mite, Oligonychus ilicis McGregor, and the two-spotted spider mite, Tetranychus urticae Koch. They are found together feeding on the same plant on the upper and underside of the leaves, respectively. Here we studied the choice for feeding sites of O. ilicis and T. urticae on strawberry plants. The first hypothesis tested whether the feeding site choice would be related to the fitness of the species. The second hypothesis dealt whether the feeding site would be determined by the presence of a heterospecific mite. We evaluated the preference, biology and reproductive success of O. ilicis and T. urticae on the under and upper side surface of strawberry leaves infested or not by the heterospecific. O. ilicis preferred to stay on the upper side surface while T. urticae preferred the underside. The preference for the leaf surface correlated with the reproductive success of the species (measured by the intrinsic growth rate). The choice pattern of feeding sites did not alter when the choice test was applied using sites previously infested by heterospecific. Although O. ilicis and T. urticae, apparently, do not interact directly for feeding sites, there is a chance that the first species induces defenses in strawberry plant enabling to reduce the fitness of the second species. The possibility of those species stay together on strawberry plant increases the damage capacity to the culture. (author)

We collected surface snow samples during the OASIS Barrow campaign in March 2009 for analysis of semi-volatile organic compounds using solid phase microextraction and gas chromatography with mass spectrometric detection (SPME-GC/MS). Additioal gab samples were taken for analysis of non-methane hydrocarbons in air. More over, we analyzed for microbial species in air and snow. Identifed organic compounds covered a wide range of functionalities andmolecular weigts, including oxygenated reactive speces such as aldehydes (e.g., hexanal to decanal), alcohols (e.g., hexanol, octanol) and aromatic species (e.g., methyl- and ethylbenzenes). Quantification data for selected aromatic species are presented with concentrations in the upper ng/L range. We will present our preliminary data on microbiological species, and will discuss the potential mplications of the results for organic snow chemistry.

    2009-11-01

    Elliot and colleagues (2006) examined the effects of experimentally induced achievement goals, proposed by the trichotomous model, on self-handicapping and performance in physical education. Our study replicated and extended the work of Elliot et al. by experimentally promoting all four goals proposed by the 2 x 2 model (Elliot & McGregor, 2001), measuring the participants' own situational achievement goals, using a relatively novel task, and testing the participants in a group setting. We used a randomized experimental design with four conditions that aimed to induce one of the four goals advanced by the 2 x 2 model. The participants (n = 138) were undergraduates who engaged in a dart-throwing task. The results pertaining to self-handicapping partly replicated Elliot and colleagues' findings by showing that experimentally promoted performance-avoidance goals resulted in less practice. In contrast, the promotion of mastery-avoidance goals did not result in less practice compared with either of the approach goals. Dart-throwing performance did not differ among the four goal conditions. Personal achievement goals did not moderate the effects of experimentally induced goals on self-handicapping and performance. The extent to which mastery-avoidance goals are maladaptive is discussed, as well as the interplay between personal and experimentally induced goals.

  5. Genetic similarity among Agistemus pallinii Matioli et al (Acari: Stigmaeidae) found in citrus orchards in Vicosa, Minas Gerais state, Brazil

    Matioli, Andre L.; Pallini, Angelo; Tavares, Mara G.

    2009-01-01

    Stigmaeidae are very important predators of mite and insect pests on several crops in Brazil. It is considered the second most important family of predatory mites in citrus orchards in Brazil. However, their identification, especially that of the members of the genus Agistemus, is rather difficult based only on morphology. Hence, this study describes the use of random amplified polymorphic DNA (RAPD-PCR) markers to determine the genetic similarity of an Agistemus pallinii Matioli et al population found in 2004 in a citrus orchard in Vicosa, Minas Gerais State, Brazil, preying on Panonychus citri (McGregor). Amplifications were performed with 12 random primers (OPAA8, OPAA19, OPAB1, OPAB5, OPAB18, OPAC9, OPAC17, OPAC19, OPAD10, OPAE9, OPAE12 and OPAE17), which generated 119 bands, with 53.8% polymorphism. The coefficients of genetic similarity among the individuals ranged from 0.68 to 0.99, indicating a high genetic similarity among them. The 3D projection analysis clustered the majority of individuals confirming their high similarity. Though individuals of A. pallinii are minute (± 360 μm long), the PCR-RAPD technique can still be used for their identification, complementing morphological analyses or for comparison of populations collected in different geographic regions. This is the fi rst molecular study carried out with stigmaeid mites. (author)

  6. Evidence for host plant preference by Iphiseiodes quadripilis (Acari: Phytoseiidae) on Citrus.

    Villanueva, Raul T; Childers, Carl C

    2006-01-01

    In this study, we present field and laboratory evidence on the preference of Iphiseiodes quadripilis (Banks) for grapefruit (Citrus paradisi Macfadyen) leaves compared with sweet orange (Citrus sinensis (L.) Osbeck) leaves. This preference was confirmed in four orchards whether leaf samples were taken from either border trees of contiguous grapefruit or sweet orange or interior row trees with both citrus species in adjacent rows. Iphiseiodes quadripilis was most abundant in grapefruit trees in spite of the greater abundance of the Texas citrus mite, Eutetranychus banksi (McGregor) (Acari: Tetranychidae) in sweet orange trees. Similar preference responses were observed in laboratory tests using a Y-tube olfactometer whether I. quadripilis were collected from sweet orange or grapefruit. Iphiseiodes quadripilis collected from grapefruit trees showed significant preference for grapefruit over sweet orange leaves in contact choice tests using an arena of alternating leaf strips (12 mm long x 2 mm wide) of sweet orange and grapefruit. However, I. quadripilis collected from sweet orange trees did not show preference for either grapefruit or sweet orange leaves. Based on these results, grapefruit leaves foster some unknown factor or factors that retain I. quadripilis in greater numbers compared with sweet orange leaves.

  8. TRANSFORMATION

    LACKS,S.A.

    2003-10-09

    Transformation, which alters the genetic makeup of an individual, is a concept that intrigues the human imagination. In Streptococcus pneumoniae such transformation was first demonstrated. Perhaps our fascination with genetics derived from our ancestors observing their own progeny, with its retention and assortment of parental traits, but such interest must have been accelerated after the dawn of agriculture. It was in pea plants that Gregor Mendel in the late 1800s examined inherited traits and found them to be determined by physical elements, or genes, passed from parents to progeny. In our day, the material basis of these genetic determinants was revealed to be DNA by the lowly bacteria, in particular, the pneumococcus. For this species, transformation by free DNA is a sexual process that enables cells to sport new combinations of genes and traits. Genetic transformation of the type found in S. pneumoniae occurs naturally in many species of bacteria (70), but, initially only a few other transformable species were found, namely, Haemophilus influenzae, Neisseria meningitides, Neisseria gonorrheae, and Bacillus subtilis (96). Natural transformation, which requires a set of genes evolved for the purpose, contrasts with artificial transformation, which is accomplished by shocking cells either electrically, as in electroporation, or by ionic and temperature shifts. Although such artificial treatments can introduce very small amounts of DNA into virtually any type of cell, the amounts introduced by natural transformation are a million-fold greater, and S. pneumoniae can take up as much as 10% of its cellular DNA content (40).

Investments in IT made by organizations have increased each year. Therefore, the purpose of the present study is to analyze the IT Business Value for Information Intensive Organizations (IIO - e.g. banks, insurance companies and securities brokers. The research method consisted of a survey that used and combined the models from Weill and Broadbent (1998 and Gregor, Martin, Fernandez, Stern and Vitale (2006. Data was gathered using an adapted instrument containing 5 dimensions (Strategic, Informational, Transactional, Transformational and Infra-structure with 27 items. The instrument was refined by employing statistical techniques such as Exploratory and Confirmatory Factorial Analysis through Structural Equations (first and second order Model Measurement. The final model is composed of four factors related to IT Business Value: Strategic, Informational, Transactional and Transformational, arranged in 15 items. The dimension Infra-structure was excluded during the model refinement process because it was discovered during interviews that managers were unable to perceive it as a distinct dimension of IT Business Value.

  10. Truthfulness in transplantation: non-heart-beating organ donation

    Potts Michael

    2007-08-01

    Full Text Available Abstract The current practice of organ transplantation has been criticized on several fronts. The philosophical and scientific foundations for brain death criteria have been crumbling. In addition, donation after cardiac death, or non-heartbeating-organ donation (NHBD has been attacked on grounds that it mistreats the dying patient and uses that patient only as a means to an end for someone else's benefit. Verheijde, Rady, and McGregor attack the deception involved in NHBD, arguing that the donors are not dead and that potential donors and their families should be told that is the case. Thus, they propose abandoning the dead donor rule and allowing NHBD with strict rules concerning adequate informed consent. Such honesty about NHBD should be welcomed. However, NHBD violates a fundamental end of medicine, nonmaleficience, "do no harm." Physicians should not be harming or killing patients, even if it is for the benefit of others. Thus, although Verheijde and his colleages should be congratulated for calling for truthfulness about NHBD, they do not go far enough and call for an elimination of such an unethical procedure from the practice of medicine.

  11. The ATLAS Overview Week in Freiburg, October 2004

    2004-01-01

    The first things that must be said are that the city of Freiburg is a very attractive location for such a meeting, encouraging a relaxed coming together of all sections of the ATLAS Community, and that the Week's activities were splendidly, (while unobtrusively), organised by our hosts, Karl Jakobs and Gregor Herten and their supporting team. The fine sunny weather contributed to our sense of well-being, of course, as did the quality of the local beer! (Some of our native English speaking colleagues were relieved to discover that what was described in restaurants and bars as 'Badisch' turned out, on the contrary, to be rather 'Good-ish' instead!!) The week began with pre-meetings of subgroups on Saturday and Sunday, and included lively discussions on how to commission the detector and on the nature and format of the ATLAS control room and its environs. These discussions were a clear indication of the optimism within the ATLAS community that physics is really beginning to appear on our horizon! During th...

    Full Text Available El bulbo y pedúnculo olfatorio humano contienen muchos grupos celulares más o menos separados que habitualmente son considerados como parte del núcleo olfatorio anterior retro-bulbar (AON. La presunción que estos grupos celulares sean considerados como extensión rostral del AON en el hemisferio rostral retrocede a la descripción de un único caso por Crosby y Humphrey (1941. Para mejorar nuestra comprensión de la anatomía del AON bulbar y peduncular humano investigamos la morfología, forma y tamaño de estas partes en este núcleo en tejido post-mortem de individuos de edades conocidas. Se obtuvieron seis bulbos y pedúnculos olfatorios, incluyendo la sustancia perforada anterior (SPA, de cerebros donados; se realizaron cortes seriales horizontales a 40µm y se tiñó con substancia de Nissl. Las neuronas de tamaño mediano a grande de esta parte del AON se tiñeron intensamente y tenían un diámetro promedio de 16µm. La reconstruc-ción tridimensional demostró que en todos los casos, excepto uno, el AON bulbar y peduncular consistieron en una cadena discontinua de grupos celulares conectados por puentes de neuropilas pobres o libres de células. El número de grupos celulares y de puentes conectores difiere en cada individuo. Concluimos que las porciones bulbar y peduncular del AON humano debería ser considerado como una especialización humana más que como una extensión rostral del área AON retro-bulbar. Esto es acorde con las propiedades neuro-clínicas previamente publicadas y la degeneración temprana selectiva, pre-clínica, de estos nichos celulares en la enfermedad neuro-degenerativa. The human olfactory bulb and peduncle contain several more or less separated cell groups that are usually regarded to be part of the retrobulbar anterior olfactory nucleus (AON.

Resultados: de los 125 diagnósticos citológicos, 94 se consideraron benignos, 4 sospechosos y 27 malignos. Estos hallazgos se compararon con el diagnóstico final de 45 lesiones malignas y 80 lesiones benignas, obtenido mediante patología quirúrgica o con un año al menos de seguimiento clínico. La comparación arrojó 30 positivos verdaderos, 78 negativos verdaderos, 1 positivo falso y 16 negativos falsos, lo que corresponde a una sensibilidad, una especificidad, un valor pronóstico positivo, un valor pronóstico negativo y una precisión del 65,2, el 98,7, el 96,8, el 83 y el 86,4%, respectivamente. Conclusión: los resultados parecen confirmar la utilidad de un abordaje en equipo eficaz de la citología con cepillo guiada por CPRE para el diagnóstico del cáncer pancreaticobiliar. Sin embargo, la sensibilidad sigue siendo más bien baja.

    Full Text Available RESUMEN Desde sus comienzos, hace dos mil años, los historiadores centraron su interés en los estratos altos de la sociedad, priorizando la esfera política. Se apoyaban en unos pocos documentos escritos dentro de un universo de relatos orales y mitos. Aquella mirada elitista, con las bases sociales y los pueblos bárbaros que los rodeaban como telón de fondo, se mantuvo hasta hace alrededor de cien años. Luego, los historiadores hicieron esfuerzos para integrar en sus páginas a quienes habían quedado en los márgenes, ampliando el enfoque y sumando fuentes de información alternativas. En América, los últimos en incorporarse fueron los indígenas, desatendidos por su condición ágrafa aunque también por criterios discriminatorios que surgieron con la colonización y tiñeron la teoría desde el siglo XIX. La Etnohistoria, que nace y se desarrolla principalmente en América desde mediados del siglo pasado, hizo grandes esfuerzos metodológicos para sumar protagonistas históricos fundamentales como los indígenas. Sin ellos no se pueden comprender algunos procesos que desembocan en el presente. Esos grupos sociales, aún en los márgenes, tenían su propia historia. Faltaba incorporarlos, como en un gran puzzle, a la Historia Universal, y para ello era necesario repensar las partes y el todo. ABSTRACT From the beginning, two thousand years ago, historians focused their interest in the upper strata of society, prioritizing the political field. They relied on a few written documents within a universe of oral histories and myths.

Then the historians made efforts to integrate into your pages to those who had been on the margins, expanding the focus and adding alternative sources of information.

  19. A search for Potential Impact Sites in Southern Argentina

    Rocca, M. C. L.

    The Southern part of Argentina is composed of five Provinces; Tierra del Fuego, Santa Cruz, Chubut, Rio Negro and Neuquen. A search for potential impact sites was performed by the author through the examination of 76 color LANDSAT satellite images ( 1:250,000 - resolution = 250 meters ) at the Instituto Geografico Militar ( IGM ) of Buenos Aires city. When a potential candidate was found a more detailed study of the site was done. If available the radar X-SAR satellite images of the Deutsche Forschungsanstalt fur Luft-und Raumfahrt, (DLR), Berlin, Germany , were also examined. The final step was to perform a review of the available published geologic information of each site at the Servicio Geologico y Minero Argentino ( SEGEMAR ), ( =Geological Survey of Argentina ), in Buenos Aires. The resulting catalogue contains information about sites where possible simple crater or complex impact structures could be present. Each case demands future detailed and `in situ' research by an impact cratering specialist. --Tierra del Fuego: TF1 ) Ushuaia 5569-II, No 218. Cerro Taarsh, Estancia San Justo.

  20. Plant physiology at the institute for philosophy in Brno in Mendel’s teacher F. Diebl textbook from 1835

    Jiří Šebánek

    2012-01-01

    Full Text Available Gregor Mendel attended lectures of F. Diebl, professor of natural history and agricultural science at the Institute of Philosophy in Brno. Diebl published his lectures in a textbook “Abhandlungen über die allgemeine und besondere Naturgeschichte, Brünn 1835.” From the textbook the level of scientific knowledge in plant biology is obvious, with which the later founder of a new field of biology – genetics got acquainted. Diebl considered germination to be a specific method of fermentation transforming seed starch into a sugary matter which nourishes the germinating plant. In the physiology of nutrition he distinguished nutrition from the soil via roots from nutrition from the air via leaves. The former is based primarily on the humus theory of A. Thaer (1809 because not until 5 years after the publication of Diebl’s textbook J. Liebig initiated the mineral theory. Diebl’s presentation of photosynthesis was based on information available at that time about the release of oxygen by green plants under conditions of light and the uptake of CO2, but he had no knowledge about the passage of CO2 into the leaves through stomata. Remarkable is Diebl’s discovery that respiration increases during flowering. Electricity is considered to be a force significantly supporting the life processes of plants. Diebl also noticed the difference between diurnal and night evaporation of water from the leaves. In his textbook growth is connected with nutrition only, as it was the entire 19th century. Stem thickening from the cambium is described very simply. Bud and root regeneration is given the term reproduction which today is commonly used in relation to sexual reproduction. Diebl considered nyctinastic movements (bending or unbending of the leaves and closing of the flowers at night to be “sleep”. He described fertilisation in a primitive way, because it was not until 1848 that the first exact description came out.

  1. Displays of emotion and citizen support for Merkel and Gysi.

    Gabriel, Oscar W; Masch, Lena

    2017-01-01

    Emotional appeals have always been an important instrument in the mobilization of political support in modern societies. As found in several experimental studies from the United States, the emotions displayed by leading politicians in their televised public appearances have an impact on the political attitudes and behaviors of the public. Positive emotions such as joy or happiness, pride, and amusement elicit a more positive assessment of politicians, whereas showing negative emotions such as anger or outrage often diminishes the public's support. This transfer of emotions from sender to recipient has been described as "emotional contagion." However, under specific circumstances, emotions expressed by politicians can result in counter-empathic reactions among recipients. To examine the role of emotions between political leaders and the public in an institutional and cultural setting outside the United States, this article presents experimental findings on the impact of emotions expressed by two leading German politicians on the German public. The study used emotional displays by Chancellor Angela Merkel and former parliamentary leader of the Left Party, Gregor Gysi, observing how their assessments by the German public changed in response to these displays. Consistent with existing research, we discovered positive effects on the evaluation of both politicians when they displayed positive emotions. However, the impact of negative emotions is different for Merkel and Gysi and can be described as contagion in the former and counter-contagion in the latter case. Furthermore, we found that individual recognition of the expressed emotions modified the effect they had on the evaluation of some leadership characteristics.

However, measuring achievement goals in a precise manner is problematic. Elliot and McGregor's Achievement Goal Questionnaire (AGQ and Elliot and Murayama's revised Achievement Goal Questionnaire (AGQ-R are widely used to assess students' achievement goals. Both instruments were developed and validated using undergraduate psychology students in the USA.Methods: In this study, our aims were to first of all, assess the construct validity of both questionnaires using a cohort of Australian pharmacy students and, subsequently, to test the generalizability and replicability of these tools more widely in schools of pharmacy in other English-speaking countries. The AGQ and the AGQ-R were administered during tutorial class time. Confirmatory factor analysis procedures, using AMOS 19 software, were performed to determine model fit.Results: In contrast to the scale developers' findings, confirmatory factor analysis supported a superior model fit for the AGQ compared with the AGQ-R, in all countries under study.Conclusion: Validating measures of achievement goal motivation for use in pharmacy education is necessary and has implications for future research. Based on these results, the AGQ will be used to conduct future cross-sectional and

    The residual effects of several reduced-risk and conventional miticides were evaluated in strawberries (Fragaria × ananassa Duchesne) on the twospotted spider mite (TSSM), Tetranychus urticae Koch (Acari: Tetranychidae) and on 2 predatory mites, Neoseiulus californicus McGregor and Phytoseiulus persimilis Athias-Henriot (Acari: Phytoseiidae). Experiments were conducted in the laboratory and greenhouse. The greenhouse experiments also tested the direct effects of the miticides on TSSM. The efficacy of conventional and reduced-risk miticides was evaluated on strawberry leaf discs and on whole plants for control of TSSM. Furthermore, the residual effects of these miticides were evaluated on whole strawberry plants against selective predatory mites. For TSSM, 5 treatments were evaluated: a conventional miticide; fenbutatin-oxide (Vendex[reg]) and 3 reduced-risk miticides; binfenazate (Acramite 50WP[reg]), activated garlic extract (Repel[reg]), sesame seed and castor oil (Wipeout[reg]), and a water-treated control. For predatory mites, the residual effects of only Acramite[reg] and Vendex[reg] were evaluated. Acramite[reg] was the most effective acaricide in reducing TSSM populations in both the laboratory and greenhouse experiments. Vendex[reg] and Wipeout[reg] were also effective in the laboratory, but did not cause significant reduction of TSSM in the greenhouse. Repel[reg] was the least effective of the 4 pesticides evaluated. Neither Acramite[reg] nor Vendex[reg] had a significant effect on either predatory mite species. However, there appeared to be more predatory mites on the Vendex[reg]-treated plants than on the Acramite[reg]-treated plants. There were significantly more predatory mites of both species on the cue plants, which were inoculated with TSSM versus the non-cue plants, which were not inoculated. (author) [es

  7. THE INFLUENCE OF VARIABLE TEMPERATURE AND HUMIDITY ON THE PREDATION EFFICIENCY OF P. PERSIMILIS, N. CALIFORNICUS AND N. FALLACIS.

    Predatory mites like Phytoseiulus persimilis Athias-Henriot, Neoseiulus californicus McGregor and N. fallacis (Garman) (Acari: Phytoseiidae) are essential in sustainable control strategies of the two-spotted spider mite Tetranychus urticae Koch (Acari: Tetranychidae) in warm greenhouse cultures to complement imited available pesticides and to tackle emerging resistance. However, in response to high energy prices, greenhouse plant breeders have recently changed their greenhouse steering strategies, allowing more variation in temperature and humidity. The impact of these variations on biological control agents is poorly understood. Therefore, we constructed functional response models to demonstrate the impact of realistic climate variations on predation efficiency. First, two temperature regimes were compared at constant humidity (70%) and photoperiod (16L:8D): DIF0 (constant temperature) and DIF15 (variable temperature with day-night difference of 15°C). At mean temperatures of 25°C, DIF15 had a negative influence on the predation efficiency of P. persimilis and N. californicus, as compared to DIF0. At low mean temperatures of 15°C, however, DIF15 showed a higher predation efficiency for P. persimilis and N. californicus. For N. fallacis no difference was observed at both 15°C and 25°C. Secondly, two humidity regimes were compared, at a mean temperature of 25°C (DIFO) and constant photoperiod (16L:8D): RHCTE (constant 70% humidity) and RHALT (alternating 40% L:70%D humidity). For P. persimilis and N. fallacis RHCTE resulted in a higher predation efficiency than RHALT, for N. californicus this effect was opposite. This shows that N. californicus is more adapted to dry climates as compared to the other predatory mites. We conclude that variable greenhouse climates clearly affect predation efficiency of P. persimilis, N. californicus and N. fallacis. To obtain optimal control efficiency, the choice of predatory mites (including dose and application frequency

    Full Text Available Biological control techniques are commonly used in many horticultural crops in Spain, however the application of these techniques to Spanish strawberries are relatively recent. In this study the effectiveness of augmentative biological control techniques to control the two main strawberry (Fragaria xananassa Duchesne pest: the two-spotted spider mite (TSSM, Tetranychus urticae Koch (Acari: Tetranychidae, and the western flower thrips (WFT, Frankliniella occidentalis (Pergande (Thysanoptera: Thripidae, through releases of the predatory mites Phytoseiulus persimilis Athias-Henriot, Neoseiulus californicus (McGregor, Amblyseius swirskii Athias-Henriot (Acari: Phytoseiidae, and Orius laevigatus (Fieber (Heteroptera: Anthocoridae were tested. Two-year results on the performance of treatments using combinations of these biocontrol agents are presented. In both years, all treatments resulted in the reduction of TSSM numbers; but no treatment was better than the release of P. persimilis alone (P < 0.05. TSSM suppression varied among crop phases being greater early in the season. None of the treatments reduced significantly WFT numbers (P < 0.05, and the established economic injury level (EIL was surpassed from March to late April in both years. However, EIL was surpassed less times when treatment included O. laevigatus (2009: 20.7%; 2010: 22.7% of samples. No effect of A. swirskii was observed when this mite was released. Results corroborate that biological control techniques for TSSM and WFT are feasible for high-plastic tunnel strawberries. Under the conditions in our study no additive effects were observed, and there was not advantage in the release of multiple natural enemies.

    A program of research is needed that assesses the psychometric properties of instruments designed to quantify students' achievement goal orientations to clarify inconsistencies across previous studies and to provide a stronger basis for future research. We conducted traditional psychometric and modern Rasch-model analyses of the Achievement Goals Questionnaire (AGQ, Elliot & McGregor, 2001) and the Patterns of Adaptive Learning Scale (PALS, Midgley et al., 2000) to provide an in-depth analysis of the two most popular instruments in educational psychology. For Study 1, 217 undergraduate students enrolled in educational psychology courses participated. Thirty-four were male and 181 were female (two did not respond). Participants completed the AGQ in the context of their educational psychology class. For Study 2, 126 undergraduate students enrolled in educational psychology courses participated. Thirty were male and 95 were female (one did not respond). Participants completed the PALS in the context of their educational psychology class. Traditional psychometric assessments of the AGQ and PALS replicated previous studies. For both, reliability estimates ranged from good to very good for raw subscale scores and fit for the models of goal orientations were good. Based on traditional psychometrics, the AGQ and PALS are valid and reliable indicators of achievement goals. Rasch analyses revealed that estimates of reliability for items were very good but respondent ability estimates varied from poor to good for both the AGQ and PALS. These findings indicate that items validly and reliably reflect a group's aggregate goal orientation, but using either instrument to characterize an individual's goal orientation is hazardous.

    The conversion of land from its native state to an agricultural use commonly results in a significant loss of soil carbon (Mann, 1985; Davidson and Ackerman, 1993). Globally, this loss is estimated to account for as much as 1/3 of the net CO2 emissions for the period of 1850 to 1980 (Houghton and others, 1983). Roughly 20 to 40 percent of original soil carbon is estimated to be lost as CO2 as a result of agricultural conversion, or "decomposition enhancement". Global models use this estimate along with land conversion data to provide agricultural contributions of CO2 emissions for global carbon budgets (Houghton and others, 1983; Schimel, 1995). Soil erosion rates are significantly (10X) higher on croplands than on their undisturbed equivalents (Dabney and others, 1997). Most of the concern over erosion is related to diminished productivity of the uplands (Stallings, 1957; McGregor and others, 1969; Rhoton, 1990) or to increased hazards and navigability of the lowlands in the late 1800's to early 1900's. Yet because soil carbon is concentrated at the soil surface, with an exponential decline in concentration with depth (Harden et al, 1999), it is clear that changes in erosion rates seen on croplands must also impact soil carbon storage and terrestrial carbon budgets as well. As yet, erosional losses of carbon are not included in global carbon budgets explicitly as a factor in land conversion nor implicitly as a portion of the decomposition enhancement. However, recent work by Lal and others (1995) and by Stallard (1998) suggests that significant amounts of eroded soil may be stored in man-made reservoirs and depositional environments as a result of agricultural conversion. Moreover, Stallard points out that eroding soils have the potential for replacing part of the carbon trapped in man-made reservoirs. If true, then the global carbon budget may grossly underestimate or ignore a significant sink term resulting from the burial of eroded soil.

  12. Neutron experiments at LAMPF

    Jain, M.

    1975-01-01

    The problem of the nucleon-nucleon force is the most fundamental in nuclear physics and is basic to particle physics. However, in the energy range from pion production threshold to 1 GeV, the N-N interaction is rather poorly determined. In general, at these energies, there is no unique set of phase shifts and coupling parameters; the I = 1 parameters are known at least quantitatively, but the I = 0 parameters are not even known qualitatively. This is illustrated by the variation of 3 S 1 phase shift from -17 to 35 0 in the three solutions of the energy-independent nucleon-nucleon phase shift analysis of Glonti. In addition, these results are in considerable disagreement with the analyses of MacGregor. This is due to the paucity of the n-p scattering data including polarization and triple scattering parameters. Furthermore, as will be shown later, there is considerable disagreement between the results from different groups in the intermediate energy region of even so basic an observable as the n-p differential cross section. Therefore, a long range program was started for the definitive determination of the n-p interaction at LAMPF energies (300 to 800 MeV). This is an ambitious project which will ultimately require the performance of many experiments. Each successive set of measurements will clarify our understainding of the n-p system to some degree and simplify the problems of the subsequent measurements. In this communication a general description of the experimental setup and the various neutron experiments performed at LAMPF is given

    Broad-band imaging and even imaging with a moderate bandpass (about 1 nm) provides a photon-rich environment, where frame selection (lucky imaging) becomes a helpful tool in image restoration, allowing us to perform a cost-benefit analysis on how to design observing sequences for imaging with high spatial resolution in combination with real-time correction provided by an adaptive optics (AO) system. This study presents high-cadence (160 Hz) G-band and blue continuum image sequences obtained with the High-resolution Fast Imager (HiFI) at the 1.5-meter GREGOR solar telescope, where the speckle-masking technique is used to restore images with nearly diffraction-limited resolution. The HiFI employs two synchronized large-format and high-cadence sCMOS detectors. The median filter gradient similarity (MFGS) image-quality metric is applied, among others, to AO-corrected image sequences of a pore and a small sunspot observed on 2017 June 4 and 5. A small region of interest, which was selected for fast-imaging performance, covered these contrast-rich features and their neighborhood, which were part of Active Region NOAA 12661. Modifications of the MFGS algorithm uncover the field- and structure-dependency of this image-quality metric. However, MFGS still remains a good choice for determining image quality without a priori knowledge, which is an important characteristic when classifying the huge number of high-resolution images contained in data archives. In addition, this investigation demonstrates that a fast cadence and millisecond exposure times are still insufficient to reach the coherence time of daytime seeing. Nonetheless, the analysis shows that data acquisition rates exceeding 50 Hz are required to capture a substantial fraction of the best seeing moments, significantly boosting the performance of post-facto image restoration.

  14. Estimation of Physiological Cost Index as an Energy Expenditure Index using MacGregor’s Equation

    2015-09-01

    Full Text Available Introduction: Physical activity and energy expenditure can be quantified by measuring heart rate, oxygen uptake and respiratory quotient. The Physiological Cost Index (PCI proposed by MacGregor is a simple and straightforward method to estimate the energy expenditure index. Here, we aim to estimate the energy expenditure among young Asian population using MacGregor’s equation. Methods: A total of 50 young randomly selected healthy females performed 50m, 100m and 150m walking test at their self-selected preferred speed. The physiological cost index values for 100 m walk at speeds slower and faster than the preferred speed were also obtained. The physiological cost index during exercise was calculated using MacGregor’s equation considering heart rate and speed of walking over the varying distances. Results: The PCI values on three different distances are consistent during self selected preferred speed. The PCI estimation on second and third tests for all three distances walked consistently reproducible. However for each distance walked, the first test the PCI was significantly higher than the second and third test values. The PCI values increased significantly when subjects walked either slower (p = 0.02 or faster (p = 0.001 than their normal preferred speed. Conclusion: The physiological cost index values were similar for varying distances walks. The PCI was the least at the preferred speed of walking and increased when the subjects either walked slower or faster than the preferred speed. The first estimation was higher than subsequent estimations. Keywords: energy expenditure index; exercise; physiological cost index. | PubMed

  15. Final Progress Report: Collaborative Research: Decadal-to-Centennial Climate & Climate Change Studies with Enhanced Variable and Uniform Resolution GCMs Using Advanced Numerical Techniques

    Fox-Rabinovitz, M; Cote, J

    2009-06-05

    The joint U.S-Canadian project has been devoted to: (a) decadal climate studies using developed state-of-the-art GCMs (General Circulation Models) with enhanced variable and uniform resolution; (b) development and implementation of advanced numerical techniques; (c) research in parallel computing and associated numerical methods; (d) atmospheric chemistry experiments related to climate issues; (e) validation of regional climate modeling strategies for nested- and stretched-grid models. The variable-resolution stretched-grid (SG) GCMs produce accurate and cost-efficient regional climate simulations with mesoscale resolution. The advantage of the stretched grid approach is that it allows us to preserve the high quality of both global and regional circulations while providing consistent interactions between global and regional scales and phenomena. The major accomplishment for the project has been the successful international SGMIP-1 and SGMIP-2 (Stretched-Grid Model Intercomparison Project, phase-1 and phase-2) based on this research developments and activities. The SGMIP provides unique high-resolution regional and global multi-model ensembles beneficial for regional climate modeling and broader modeling community. The U.S SGMIP simulations have been produced using SciDAC ORNL supercomputers. Collaborations with other international participants M. Deque (Meteo-France) and J. McGregor (CSIRO, Australia) and their centers and groups have been beneficial for the strong joint effort, especially for the SGMIP activities. The WMO/WCRP/WGNE endorsed the SGMIP activities in 2004-2008. This project reflects a trend in the modeling and broader communities to move towards regional and sub-regional assessments and applications important for the U.S. and Canadian public, business and policy decision makers, as well as for international collaborations on regional, and especially climate related issues.

    Clinical case series and risk factor analysis of dysphagia after occipitospinal fusion (OSF). The aim of this study was to develop new criteria to avoid postoperative dysphagia by analyzing the relationship among the craniocervical alignment, the oropharyngeal space, and the incidence of dysphagia after OSF. Craniocervical malalignment after OSF is considered to be one of the primary triggers of postoperative dysphagia. However, ideal craniocervical alignment has not been confirmed. Thirty-eight patients were included. We measured the O-C2 angle (O-C2A) and the pharyngeal inlet angle (PIA) on the lateral cervical radiogram at follow-up. PIA is defined as the angle between McGregor's line and the line that links the center of the C1 anterior arch and the apex of cervical sagittal curvature. The impact of these two parameters on the diameter of pharyngeal airway space (PAS) and the incidence of the dysphagia were analyzed. Six of 38 cases (15.8%) exhibited the dysphagia. A multiple regression analysis showed that PIA was significantly correlated with PAS (β = 0.714, P = 0.005). Receiver-operating characteristic curves showed that PIA had a high accuracy as a predictor of the dysphagia with an AUC (area under the curve) of 0.90. Cases with a PIA less than 90 degrees showed significantly higher incidence of dysphagia (31.6%) than those with a 90 or more degrees of PIA (0.0%) (P = 0.008). Our results indicated that PIA had the high possibility to predict postoperative dysphagia by OSF with the condition of PIA dysphagia. 4.

    2011-12-01

    Full Text Available It is with both pleasure and sadness that we dedicate this special climate change issue of Portal to the late Dr. Stephen H. Schneider. Steve, as he was known to his friends and colleagues, was as rare a bird as any he sought out in his passion as a birdwatcher. A brilliant climate scientist, author of countless books and papers, path breaking inter-disciplinarian, eminent public communicator, mentor to dozens of young scholars; the list of roles and adulatory adjectives could fill an IPCC special report. Steve would have appreciated this special issue, with its multidisciplinary approach, and its quest for solutions based on analytical scholarship. He understood better than most the inseparability of normative and descriptive concerns, the need for academics and scientists of all kinds to be involved with public processes of communication, policy design and deliberation. While his last book was called “Science as a Contact Sport,” the unspoken title of his career might have been “Science as a Public Service.” He was endlessly testifying, consulting and giving interviews, and encouraged others to learn to do the same. Notwithstanding a battle with lymphoma in the last decade (chronicled in the wonderful book The Patient from Hell, Steve maintained a frenetic level of activity and was still going strong when he was felled by a pulmonary embolism in July of 2010 at age 65. He leaves behind a legacy embodied in his publications, institutions like the IPCC and the journal Climatic Change, and in the hearts and minds of the countless persons he interacted with, mentored, and loved. Exuberant, passionate, full of warmth and good humor, Steve was a mensch among mensches. He will be sorely missed. Paul Baer, with the assistance of Terry Root and Ian McGregor.

    1978-08-01

    A case-control study was made on female breast cancer cases and their matched controls in the Life Span Study sample. The index cases were detected during 1958-69 among the 251 breast cancer cases ascertained originally by McGregor et al. The purpose of this study was to define the epidemiologic risk factors of breast cancer among Japanese women, to test for radiation effects in the presence of other risk factors, and to search for interactions. The survey was conducted by interview at home visits for those residing in the Hiroshima and Nagasaki areas, and by mail survey for others. The interview was carried out by several trained interviewers. Information concerning suspected risk factors of breast cancer, such as familial history, education, age at menarche and menopause, marital history, reproductive history, history of breast feeding, etc., was collected for both index cases and controls. Out of 183 original pairs, analysis was made on 164 pairs with available information for both the index and control, using the method of matched samples described by Mantel and Haenszel. There was enhancement of risk for those exposed to high radiation dose (100 rad or more). Although most major results were similar to those of previous studies, a significant increase of risk was observed among those under one of the following conditions: actual duration of marriage was less than 10 years; number of pregnancies was two or less; and age at delivery of first live born child was 27 or over. These factors had a mutual interrelationship and cases with two or more of these risk factors showed higher risk than those with one. Additive interrelationship was demonstrated between radiation dose and these marital or reproductive risk factors in elevating the relative risk of breast cancer. (author)

  19. Context-dependent neural activation: internally and externally guided rhythmic lower limb movement in individuals with and without neurodegenerative disease

    Full Text Available Parkinson’s Disease (PD is a neurodegenerative disorder that has received considerable attention in allopathic medicine over the past decades. However, it is clear that, to date, pharmacological and surgical interventions do not fully address symptoms of PD and patients’ quality of life. As both an alternative therapy and as an adjuvant to conventional approaches, several types of rhythmic movement (e.g., movement strategies, dance, tandem biking, tai chi have shown improvements to motor symptoms, lower limb control and postural stability in people with PD (Amano, Nocera, Vallabhajosula, Juncos, Gregor, Waddell et al., 2013; Earhart, 2009; M.

However, while these programs are increasing in number, still little is known about the neural mechanisms underlying motor improvements attained with such interventions. Studying limb motor control under task specific contexts can help determine the mechanisms of rehabilitation effectiveness. Both internally guided (IG and externally guided (EG movement strategies have evidence to support their use in rehabilitative programs. However, there appears to be a degree of differentiation in the neural substrates involved in IG versus EG designs. Because of the potential task specific benefits of rhythmic training within a rehabilitative context, this report will consider the use of IG and EG movement strategies, and observations produced by functional magnetic resonance imaging (fMRI and other imaging techniques. This review will present findings from lower limb imaging studies, under IG and EG conditions for populations with and without movement disorders. We will discuss how these studies might inform movement disorders rehabilitation (in the form of rhythmic, music-based movement training and highlight research gaps.

    Full Text Available Considering the importance yet paucity of help-seeking in e-learning, the present study investigated the motivational antecedents of help-seeking among online college students. We explored and compared the influences of achievement approach goals from the old and new achievement motivation models (Elliot & McGregor, 2001; Elliot, Murayama, & Pekrun, 2011 on online students’ help-seeking through intrinsic/extrinsic motivation. Path analyses were used to test two models of help-seeking among college students from four online educational psychology classes (N = 93 based on the two models of achievement goals. Our results showed that the new 3 × 2 model was a better fit than the old 2 × 2 model, suggesting that the achievement approach goals of the new model differ from those of the old model conceptually as Elliot, Murayama, and Pekrun (2011 posited. Second, our results revealed both unexpected direct and indirect positive influence of performance- and other-approach goals on online students’ help-seeking behaviour through extrinsic motivation. Third, while mastery-approach goals indirectly predicted help-seeking through intrinsic motivation, self- and task-approach predicted help-seeking in a dramatically different manner. Self-approach goals displayed indirect influence on help-seeking through intrinsic motivation similar to mastery-approach, yet task-approach displayed a negative direct influence on help-seeking. These results suggested the potential positive impact of self-approach and the detrimental influence of task-approach goals on help-seeking in e-learning environment. Conceptual issues and pedagogical implications for online instructions are discussed.

  2. ‘Teach, reduce and discharge’: Community nurses’ textual production of ‘independence’ and the coordination of discharge from home care services

    Full Text Available Over the past three decades, the Canadian healthcare system has undergone significant reform and restructuring. As a result, healthcare and healthcare costs are relocated from hospitals to the community (McGregor, 2001. Text-based technology is increasingly used to standardize care and contain healthcare spending. This paper examines an example of a text-based technology used in the School Health Support Services programme for students with diabetes in Ontario, Canada. Using institutional ethnography, the inquiry starts with parents’ concerns regarding the premature termination of nursing care for their children with diabetes at school. The exploration shows how these parents’ concerns are hooked into the institutional work of assessment for service discharge conducted by the Community Care Access Centre (CCAC care coordinators. The analysis shows how the institutional category of ‘independence’ coordinates the service discharge work of the CCAC care coordinators with that of the nursing work of community nurses at school. The activation of the category of ‘independence’ by the nurses mediates their work, orienting their focus away from providing direct nursing care, and towards transferring primary care to children with diabetes. Children doing diabetes self-care work at school is then written up in nursing texts to stand in for children’s ability to manage diabetes ‘independently’. The textual production of ‘independence’ enables the next institutional course of action, that is, the discharge of children from nursing services at school. In this process, children with diabetes are drawn into doing the discharge work that ultimately serves the cost-containment interests of the institution. This institutional process also functions to obscure important actualities: It obscures how children’s ‘independence’ is co-created on a daily basis with their parents and relies on their parents’ work, and it discounts the

Por otra parte, también celebramos los 150 años de la primera edicion de “The Origin of species by means of natural selection, or the preservation of favoured races in the struggle for life”. En la primera parte se mostraran algunos elementos históricos relacionados con la filosofía zoológica y el contexto político de su nacimiento. Posteriormente se revisaran los principales conceptos darwinianos relacionados con la herencia y sus consecuencias en la formación de la disciplina llamada genética, se estudiara el caso especial de Gregor Mendel y finalmente se mostraran las implicaciones actuales en nuestra interpretación de la teoría evolutiva.

    Before using three-dimensional (3D) magnetohydrodynamical (MHD) simulations of the solar photosphere in the determination of elemental abundances, one has to ensure that the correct amount of magnetic flux is present in the simulations. The presence of magnetic flux modifies the thermal structure of the solar photosphere, which affects abundance determinations and the solar spectral irradiance. The amount of magnetic flux in the solar photosphere also constrains any possible heating in the outer solar atmosphere through magnetic reconnection. We compare the polarization signals in disk-center observations of the solar photosphere in quiet-Sun regions with those in Stokes spectra computed on the basis of 3D MHD simulations having average magnetic flux densities of about 20, 56, 112, and 224 G. This approach allows us to find the simulation run that best matches the observations. The observations were taken with the Hinode SpectroPolarimeter (SP), the Tenerife Infrared Polarimeter (TIP), the Polarimetric Littrow Spectrograph (POLIS), and the GREGOR Fabry–Pèrot Interferometer (GFPI), respectively. We determine characteristic quantities of full Stokes profiles in a few photospheric spectral lines in the visible (630 nm) and near-infrared (1083 and 1565 nm). We find that the appearance of abnormal granulation in intensity maps of degraded simulations can be traced back to an initially regular granulation pattern with numerous bright points in the intergranular lanes before the spatial degradation. The linear polarization signals in the simulations are almost exclusively related to canopies of strong magnetic flux concentrations and not to transient events of magnetic flux emergence. We find that the average vertical magnetic flux density in the simulation should be less than 50 G to reproduce the observed polarization signals in the quiet-Sun internetwork. A value of about 35 G gives the best match across the SP, TIP, POLIS, and GFPI observations.

    The Tularosa-Hueco basin in south-central New Mexico has long been known as an extensional area of high heat flow. Much of the basin is within the Fort Bliss military reservation, which is an exceptionally high value customer for power independent of the regional electric grid and for direct use energy in building climate control. A series of slim holes drilled in the 1990s established the existence of a thermal anomaly but not its practical value. This study began in 2009 with a demonstration of new exploration drilling technology. The subsequent phases reported here delivered a useful well, comparative exploration data sets and encouragement for further development. A production-size well, RMI56-5, was sited after extensive study of archival and newly collected data in 2010-2011. Most of 2012 was taken up with getting state and Federal authorities to agree on a lead agency for permitting purposes, getting a drilling permit and redesigning the drilling program to suit available equipment. In 2013 we drilled, logged and tested a 924 m well on the McGregor Range at Fort Bliss using a reverse circulation rig. Rig tests demonstrated commercial permeability and the well has a 7-inch slotted liner for use either in production or injection. An August 2013 survey of the completed well showed a temperature of 90 C with no reversal, the highest such temperature in the vicinity. The well’s proximity to demand suggests a potentially valuable resource for direct use heat and emergency power generation. The drilling produced cuttings of excellent size and quality. These were subjected to traditional analyses (thin sections, XRD) and to the QEMScan™ for comparison. QEMScan™ technology includes algorithms for determining such properties of rocks as density, mineralogy, heavy/light atoms, and porosity to be compared with direct measurements of the cuttings. In addition to a complete cuttings set, conventional and resistivity image logs were obtained in the open hole before

    Full Text Available Eutetranychus banksi (McGregor, 1914 is a phytophagous, polyphagous and cosmopolitan species recorded on 23 plant families in 24 countries in North, Central and South Americas, Europe, Asia, and Africa. Specimens of E. banksi present morphological variability among individuals of the same population and also among populations from different host species, being commonly referred to as a polytypic species, despite the fact that studies based on meristic comparisons of these populations are lacking. Also, there is no data available in the literature on the biological life tables of E. banksi on different hosts. Specimens collected in Brazil, Guadeloupe, Martinique, Mexico, and Paraguay were investigated in order to recognize morphological patterns among populations from different localities and hosts. A redescription of the species is provided based on data both from literature and new observations. Also, the biological cycle on three hosts, experiments of hosts exchange and the possibility of interbreeding in individuals originating from different populations were evaluated. Significant differences in the morphology of the females of different populations were detected when comparing the different hosts. The length of the dorsal pairs of setae v2, sc2, c1, c3, e1 and h1 differentiated the specimens of the populations collected from Citrus sp. from those of Hevea brasiliensis Muell. Arg. and Pachira aquatica Aubl.. Herein we observed significant variation among the life cycle of this species on the three hosts studied. When a substrate different from the one where the mites were collected was used for the biological cycle essay, significant variation was observed in several parameters such as average oviposition rate, events of arrenothoky, and sex ratio. Interbreeding with populations collected from Citrus sinensis and P. aquatica resulted in no descendants, although mating was observed.

To defend the mother that is murdering her new-born child in the following conditions from a way too harsh punishment, it was considered necessary to interleave a distinct criminal act of manslaughter different from the criminal offence of intentional murder. This crime was created due to the objective and subjective factors proving that the wrongdoing provided in article 147 from the Criminal code of the Republic Moldova, is offence of murder but with extenuating circumstances and with particular differences from the other crimes against the life and health of the human being. The authors of this study have offered a great number of opinions, legal provisions and law-suits, which finally induced to creation of extremely comprehensive penal doctrine concerning the crime of neonaticide.

Extreme fasting is still reported, but data for Africa are scarce. Starving in hot climates leads to challenges arising from dehydration, hypotension, metabolic disturbances, and complications during induction of anesthesia. The purpose of this study was to evaluate the scope of the problem, identify possible reasons for this, and propose realistic solutions.Methods: We performed eleven prospective audits between 2008 and 2013 in Malawi to improve our preoperative fasting times. In total, 631 children (aged 3 days to 13 years were monitored. Training was provided, and the results were measured using a visual analog scale.Results: In 2008, the baseline audit showed a mean fasting time (MFT of 13.48 hours (31 patients. Training reduced the MFT to 8.77 hours (73 patients and 3.2 hours (35 patients in 2009. Without training, the MFT increased to 4.6 hours (35 patients in 2010 and to 10.2 hours (50 patients in 2011.

  15. Long-term iron deficiency: Tracing changes in the proteome of different pea (Pisum sativum L.) cultivars.

    Meisrimler, Claudia-Nicole; Wienkoop, Stefanie; Lyon, David; Geilfus, Christoph-Martin; Lüthje, Sabine

    Iron deficiency (-Fe) is one of the major problems in crop production. Dicots, like pea (Pisum sativum L.), are Strategy I plants, which induce a group of specific enzymes such as Fe(III)-chelate reductase (FRO), Fe responsive transporter (IRT) and H(+)-ATPase (HA) at the root plasma membrane under -Fe. Different species and cultivars have been shown to react diversely to -Fe. Furthermore, different kinds of experimental set-ups for -Fe have to be distinguished: i) short-term vs. long-term, ii) constant vs. acute alteration and iii) buffered vs. unbuffered systems. The presented work compares the effects of constant long-term -Fe in an unbuffered system on roots of four different pea cultivars in a timely manner (12, 19 and 25days). To differentiate the effects of -Fe and plant development, control plants (+Fe) were analyzed in comparison to -Fe plants. Besides physiological measurements, an integrative study was conducted using a comprehensive proteome analysis. Proteins, related to stress adaptation (e.g. HSP), reactive oxygen species related proteins and proteins of the mitochondrial electron transport were identified to be changed in their abundance. Regulations and possible functions of identified proteins are discussed. Pea (Pisum sativum L.) belongs to the legume family (Fabaceae) and is an important crop plant due to high Fe, starch and protein contents. According to FAOSTAT data (September 2015), world production of the garden pea quadrupled from 1970 to 2012. Since the initial studies by Gregor Mendel, the garden pea became the most-characterized legume and has been used in numerous investigations in plant biochemistry and physiology, but is not well represented in the "omics"-related fields. A major limitation in pea production is the Fe availability from soils. Adaption mechanisms to Fe deficiency vary between species, and even cultivars have been shown to react diversely.

    The demand for an eHealth-ready and adaptable workforce is placing increasing pressure on universities to deliver eHealth education. At present, eHealth education is largely focused on components of eHealth rather than considering a curriculum-wide approach. This study aimed to develop a framework that could be used to guide health curriculum design based on current evidence, and stakeholder perceptions of eHealth capabilities expected of tertiary health graduates. A 3-phase, mixed-methods approach incorporated the results of a literature review, focus groups, and a Delphi process to develop a framework of eHealth capability statements. Participants (N=39) with expertise or experience in eHealth education, practice, or policy provided feedback on the proposed framework, and following the fourth iteration of this process, consensus was achieved. The final framework consisted of 4 higher-level capability statements that describe the learning outcomes expected of university graduates across the domains of (1) digital health technologies, systems, and policies; (2) clinical practice; (3) data analysis and knowledge creation; and (4) technology implementation and codesign. Across the capability statements are 40 performance cues that provide examples of how these capabilities might be demonstrated. The results of this study inform a cross-faculty eHealth curriculum that aligns with workforce expectations. There is a need for educational curriculum to reinforce existing eHealth capabilities, adapt existing capabilities to make them transferable to novel eHealth contexts, and introduce new learning opportunities for interactions with technologies within education and practice encounters. As such, the capability framework developed may assist in the application of eHealth by emerging and existing health care professionals. Future research needs to explore the potential for integration of findings into workforce development programs. ©Melissa Brunner, Deborah McGregor

    The joint U.S-Canadian project has been devoted to: (a) decadal climate studies using developed state-of-the-art GCMs (General Circulation Models) with enhanced variable and uniform resolution; (b) development and implementation of advanced numerical techniques; (c) research in parallel computing and associated numerical methods; (d) atmospheric chemistry experiments related to climate issues; (e) validation of regional climate modeling strategies for nested- and stretched-grid models. The variable-resolution stretched-grid (SG) GCMs produce accurate and cost-efficient regional climate simulations with mesoscale resolution. The advantage of the stretched grid approach is that it allows us to preserve the high quality of both global and regional circulations while providing consistent interactions between global and regional scales and phenomena. The major accomplishment for the project has been the successful international SGMIP-1 and SGMIP-2 (Stretched-Grid Model Intercomparison Project, phase-1 and phase-2) based on this research developments and activities. The SGMIP provides unique high-resolution regional and global multi-model ensembles beneficial for regional climate modeling and broader modeling community. The U.S SGMIP simulations have been produced using SciDAC ORNL supercomputers. The results of the successful SGMIP multi-model ensemble simulations of the U.S. climate are available at the SGMIP web site (http://essic.umd.edu/~foxrab/sgmip.html) and through the link to the WMO/WCRP/WGNE web site: http://collaboration.cmc.ec.gc.ca/science/wgne. Collaborations with other international participants M. Deque (Meteo-France) and J. McGregor (CSIRO, Australia) and their centers and groups have been beneficial for the strong joint effort, especially for the SGMIP activities. The WMO/WCRP/WGNE endorsed the SGMIP activities in 2004-2008. This project reflects a trend in the modeling and broader communities to move towards regional and sub-regional assessments and

    Full Text Available Despite the importance of peach (Prunus persica (L. Batsch in Rio Grande do Sul, little is known about mites fluctuation population considered important to this crop. The objective of this study was to know the population diversity and fluctuation of mite species associated with Premier and Eldorado varieties in Roca Sales and Venâncio Aires counties, Rio Grande do Sul. The study was conducted from July 2008 to June 2009 when 15 plants were randomly chosen in each area. The plants were divided in quadrants and from each one a branch was chosen from which three leaves were removed: one collected in the apical region, another in the medium and the other in the basal region, totalizing 180 leaves/area. Five of the most abundant associated plants were collected monthly in enough amounts for the screening under the stereoscopic microscope during an hour. A total of 1,124 mites were found belonging to 14 families and 28 species. Tetranychus ludeni Zacher, 1913, Panonychus ulmi (Koch, 1836 and Mononychellus planki (McGregor, 1950 were the most abundant phytophagous mites, whereas Typhlodromalus aripo Deleon, 1967 and Phytoseiulus macropilis (Banks, 1904 the most common predatory mites.

    First on sky adaptive optics experiments were performed on the Dunn Solar Telescope on 1979, with a shearing interferometer and limited success. Those early solar adaptive optics efforts forced to custom-develop many components, such as Deformable Mirrors and WaveFront Sensors, which were not available at that time. Later on, the development of the correlation Shack-Hartmann marked a breakthrough in solar adaptive optics. Since then, successful Single Conjugate Adaptive Optics instruments have been developed for many solar telescopes, i.e. the National Solar Observatory, the Vacuum Tower Telescope and the Swedish Solar Telescope. Success with the Multi Conjugate Adaptive Optics systems for GREGOR and the New Solar Telescope has proved to be more difficult to attain. Such systems have a complexity not only related to the number of degrees of freedom, but also related to the specificities of the Sun, used as reference, and the sensing method. The wavefront sensing is performed using correlations on images with a field of view of 10", averaging wavefront information from different sky directions, affecting the sensing and sampling of high altitude turbulence. Also due to the low elevation at which solar observations are performed we have to include generalized fitting error and anisoplanatism, as described by Ragazzoni and Rigaut, as non-negligible error sources in the Multi Conjugate Adaptive Optics error budget. For the development of the next generation Multi Conjugate Adaptive Optics systems for the Daniel K. Inouye Solar Telescope and the European Solar Telescope we still need to study and understand these issues, to predict realistically the quality of the achievable reconstruction. To improve their designs other open issues have to be assessed, i.e. possible alternative sensing methods to avoid the intrinsic anisoplanatism of the wide field correlation Shack-Hartmann, new parameters to estimate the performance of an adaptive optics solar system, alternatives to

    Full Text Available Whatever people do in large or small social groups, the question always arises: what factors determine the effectiveness of these groups and what are specific features of group management? While studying in largely the same, researchers from different scientific schools and various sciences put attention to different objects and use different terminology: some say the leadership styles, some speak about the managerial style, other – about the particularities of leadership, and the third about self-managed teams. The main leadership factors, distinguished by researchers, form the model subject of study or complement and clarify the “basic” model of relevant scientific schools. In the first case the model is often expressed schematically, while the second it is more often described verbally. The difficulty of comparing models of different schools, usually lead to either the conceptual rejection of their bases, or disregard to many significant models because of their anticipated heterogeneity. So the task of this article is to overcome the apparent incompatibility of the different authors’ approaches, it allows “not multiply entities” and seek deep similarity of ideas developed over many decades by different researchers. Using the schematic pairwise comparison of numerous models of management and leadership, the author reveals the conceptual validity of some components and possible redundancy (from a historical perspective of others. When this is considered in detail the transition from 1D to 2D, and then to 3D models of leadership-management and related models: Lajkert’s continuum, managerial grid of Blake-Mouton, model of Aristotle, styles by Lewin, Tannenbaum-Schmidt and Hersey-Blanchard, two theories of McGregor, model of managerial competencies and levels of Covey leadership development, strategies in conflict of Thomas-Kilmann and cubic cultural-values model of leadership from Zankovsky.

  1. Impact of sulfur on density of Tetranychus pacificus (Acari: Tetranychidae) and Galendromus occidentalis (Acari: Phytoseiidae) in a central California vineyard.

    Costello, Michael J

    2007-01-01

    Sulfur is the oldest and most widely used fungicide in the vineyards of California, where it is used for control of powdery mildew (Uncinula necator [Schw.] Burr). For decades, sulfur use has been associated with outbreaks of Tetranychus pacificus McGregor (Acari: Tetranychidae) on cultivated grapes in the San Joaquin Valley. I undertook large-scale field studies to test this association, to evaluate the impact of sulfur on Galendromus occidentalis (Nesbit) (Acari: Phytoseiidae), a major predator of T. pacificus, and to determine if timing of sulfur applications with respect to grape bloom has an impact on T. pacificus density. The studies took place in a 32 ha vineyard in Fresno County, and all fungicide applications were made with commercial-scale equipment. In 1998 a 'high sulfur' treatment, a combination of wettable sulfur and sulfur dust, was compared to 'low sulfur,' in which demethylation inhibitor (DMI) fungicides partially substituted for sulfur. In 1999 treatments were 'sulfur,' 'DMI,' 'sulfur pre-bloom' (here sulfur was applied prior to grape bloom, in late May, and then DMIs were applied until mid-season) and 'sulfur post-bloom' (the reverse of 'sulfur pre-bloom'). In each year, the T. pacificus population increase came after the end of fungicide applications, and results clearly show a relationship between sulfur use and T. pacificus density. In 1998, mean T. pacificus density was 2.7 times higher and mean G. occidentalis density 2.5 times higher in 'high sulfur' compared to 'low sulfur.' In 1999, the highest T. pacificus counts were in the 'sulfur' and 'sulfur pre-bloom' treatments, 4.8 times higher than 'sulfur post-bloom' and 2 times higher than 'DMIs.' Density of G. occidentalis was 2.3 times as high in 'sulfur' or 'sulfur pre-bloom' than 'DMIs.' The predator/prey ratio was not significantly different among treatments in 1998, but in 1999 it was highest in the 'sulfur pre-bloom' treatment. In 1999, density of Homeopronematus anconai (Baker) (Acari

  2. Interannual drivers of the seasonal cycle of CO2 in the Southern Ocean

    2018-04-01

    Resolving and understanding the drivers of variability of CO2 in the Southern Ocean and its potential climate feedback is one of the major scientific challenges of the ocean-climate community. Here we use a regional approach on empirical estimates of pCO2 to understand the role that seasonal variability has in long-term CO2 changes in the Southern Ocean. Machine learning has become the preferred empirical modelling tool to interpolate time- and location-restricted ship measurements of pCO2. In this study we use an ensemble of three machine-learning products: support vector regression (SVR) and random forest regression (RFR) from Gregor et al. (2017), and the self-organising-map feed-forward neural network (SOM-FFN) method from Landschützer et al. (2016). The interpolated estimates of ΔpCO2 are separated into nine regions in the Southern Ocean defined by basin (Indian, Pacific, and Atlantic) and biomes (as defined by Fay and McKinley, 2014a). The regional approach shows that, while there is good agreement in the overall trend of the products, there are periods and regions where the confidence in estimated ΔpCO2 is low due to disagreement between the products. The regional breakdown of the data highlighted the seasonal decoupling of the modes for summer and winter interannual variability. Winter interannual variability had a longer mode of variability compared to summer, which varied on a 4-6-year timescale. We separate the analysis of the ΔpCO2 and its drivers into summer and winter. We find that understanding the variability of ΔpCO2 and its drivers on shorter timescales is critical to resolving the long-term variability of ΔpCO2. Results show that ΔpCO2 is rarely driven by thermodynamics during winter, but rather by mixing and stratification due to the stronger correlation of ΔpCO2 variability with mixed layer depth. Summer pCO2 variability is consistent with chlorophyll a variability, where higher concentrations of chlorophyll a correspond with lower pCO2

This method promises one pot synthesis and concomitant bio-functionalization, is devoid of toxic chemicals, does not require complicated apparatus, can be combined with natural stabilizers, is directly biocompatible, and has high particle size uniformity. Size control and reduction is generally determined by the laser settings; that the size and size distribution scales with laser fluence is well described. Conversely, the effect of the laser repetition rate on the final nanoparticle product in laser ablation is less well-documented, especially in the presence of stabilizers. Here, the influence of the laser repetition rate during laser ablation synthesis of silver nanoparticles in the presence of starch as a stabilizer was investigated. The increment of the repetition rate does not negatively influence the ablation efficiency, but rather shows increased productivity, causes a red-shift in the plasmon resonance peak of the silver–starch nanoparticles, an increase in mean particle size and size distribution, and a distinct lack of agglomerate formation. Optimal results were achieved at 10 Hz repetition rate, with a mean particle size of ~10 nm and a

    Full Text Available In 1865, Gregor Mendel presented the lectures 'Experiments in Plant Hybridization' concerning his results from cross-breeding experiments with different types of garden pea, performed in his monastery garden in Brno. Mendel studied easily observed pairs of opposite traits, such as purple or white flower, and discovered dominant and recessive traits. He concluded that parents pass separate and distinct factors (today called genes on to their offspring that are responsible for inherited traits. However, the scientific community did not understand that; indeed it was the beginning of what becomes genetics. The lectures published in 1866, Mendel sent to more than 30 biologists across Europe, but almost no one commented them. In the next 35 years, these papers were only three times cited. The genetics became more important at the beginning of the 20th century, when three different research groups (Hugo de Vries, Carl Erich Correns and Erich von Tschermak with their co-workers independently re-discovered Mendel's Laws of inheritance. However, as soon as the work was rediscovered, it created controversy. The closeness of Mendel's experimental observations to those predicted by his theories has led to numerous articles and ongoing debate about whether the data could have been obtained in the published form without some falsification. There have been many plausible arguments made for and against this view by a range of eminent geneticists and statisticians. Some have gone so far, as to suggest that the theories ensued from Mendel's two laws were not even correctly formulated in his original paper. The strongest supporters of Mendel's theory became biologist William Bateson and zoologist and geneticist Thomas Hunt Morgan. Morgan argued that genes are located on chromosomes and that the cells chromosomes hold the actual hereditary material, thus created what is now known as classical genetics. For his discovery concerning the role play by the chromosome in

    The COSMO is a facility dedicated to observing coronal and chromospheric magnetic fields. It will be located on a mountaintop in the Hawaiian Islands and will replace the current Mauna Loa Solar Observatory (MLSO). COSMO will provide unique observations of the global coronal magnetic fields and its environment to enhance the value of data collected by other observatories on the ground (e.g. SOLIS, BBO NST, Gregor, ATST, EST, Chinese Giant Solar Telescope, NLST, FASR) and in space (e.g. SDO, Hinode, SOHO, GOES, STEREO, Solar-C, Solar Probe+, Solar Orbiter). COSMO will employ a fleet of instruments to cover many aspects of measuring magnetic fields in the solar atmosphere. The dynamics and energy flow in the corona are dominated by magnetic fields. To understand the formation of CMEs, their relation to other forms of solar activity, and their progression out into the solar wind requires measurements of coronal magnetic fields. The large aperture coronagraph, the Chromospheric and Prominence Magnetometer and the K-Coronagraph form the COSMO instrument suite to measure magnetic fields and the polarization brightness of the low corona used to infer electron density. The large aperture coronagraph will employ a 1.5 meter fuse silica singlet lens, birefringent filters, and a spectropolarimeter to cover fields of view of up to 1 degree. It will observe the corona over a wide range of emission lines from 530.3 nm through 1083.0 nm allowing for magnetic field measurements over a wide range of coronal temperatures (e.g. FeXIV at 530.3 nm, Fe X at 637.4 nm, Fe XIII at 1074.7 and 1079.8 nm. These lines are faint and require the very large aperture. NCAR and NSF have provided funding to bring the large aperture coronagraph to a preliminary design review state by the end of 2013. As with all data from Mauna Loa, the data products from COSMO will be available to the community via the Mauna Loa website: http://mlso.hao.ucar.edu

    dominant lighting technology due to its superior electrical to optical conversion efficiency. A unique LED structure based on CdS is presented by Ye et al [8]. A detailed study by Nguyen et al [9] provides a fundamental understanding of the non-radiative recombination mechanisms in GaN-based white light emitting nanowire diodes grown on Si substrates. Another application of III-nitrides is in photovoltaic devices (solar cells) [10]. InGaN is the only semiconductor alloy whose energy bandgap can be continuously varied across nearly the entire solar spectrum, promising a new generation of solar cells. Another potentially important application for nanowires is the efficient production of H2 from the photocatalytic splitting of water, where the H2 can be used as an energy carrier. Water splitting based on unique nanostructures include Fe2O3 [11], CuS/ZnO [12], and ZnO/Si [13]. Another candidate for photocatalysis, among other applications, is copper oxide nanowires, reviewed by Gregor et al [14].

Nas duas primeiras datas de avaliação, todos os produtos apresentaram valores de mortalidade significativamente diferentes da testemunha tratada com água. Seis dias após a aplicação, propargite, cyhexatin e cyfluthrin apresentaram mortalidade de aproximadamente 30%, enquanto a mortalidade nos tratamentos azimphos-methyl e carbaryl apresentou níveis estatisticamente similares aos da testemunha. Dez dias após a aplicação, a mortalidade em todos os tratamentos não diferiu significativamente da testemunha. O efeito de todos os produtos apresentou declínio progressivo ao longo do período de observação, sendo significativa a 1% de probabilidade a regressão linear negativa para os valores obtidos. Os maiores efeitos negativos sobre a sobrevivência de N. californicus corresponderam aos acaricidas testados

  12. The evaluation of the statistical monomineral thermobarometric methods for the reconstruction of the lithospheric mantle structure

    2009-04-01

    The modified versions of the thermobarometers for the mantle assemblages were revised sing statistical calibrations on the results of Opx thermobarometry. The modifications suggest the calculation of the Fe# of coexisting olivine Fe#Ol according to the statistical approximations by the regressions obtained from the xenoliths from kimberlite data base including >700 associations. They allow reproduces the Opx based TP estimates and to receive the complete set of the TP values for mantle xenoliths and xenocrysts. For GARNET Three variants of barometer give similar results. The first is published (Ashchepkov, 2006). The second is calculating the Al2O3 from Garnet for Orthopyroxene according to procedure: xCrOpx=Cr2O3/CaO)/FeO/MgO/500 xAlOpx=1/(3875*(exp(Cr2O3^0.2/CaO)-0.3)*CaO/989+16)-XcrOpx Al2O3=xAlOp*24.64/Cr2O3^0.2*CaO/2.+FeO*(ToK-501)/1002 And then it suppose using of the Al2O3 in Opx barometer (McGregor, 1974). The third variant is transformation of the G. Grutter (2006) method by introducing of the influence of temperature.

    Full Text Available En este trabajo se describe la anatomía foliar de Sabal mauritiiformis, S. mexicana y S. yapa tres de las cuatro especies más representativas que se desarrollan en la Península de Yucatán, México. Tienen diversos usos locales como el techado de viviendas tradicionales, consumo de frutos, consumo de yemas apicales, elaboración de sombreros, escobas y artesanías. Las muestras de hojas se colectaron en una vegetación secundaria de la selva mediana subperennifolia en Quintana Roo y en dos solares de Yucatán. Se obtuvieron ejemplares de herbario y muestras de lámina y pecíolo que se fijaron en una solución de formalina-alcohol-ácido acético. Se hicieron cortes transversales de lámina y pecíolo y se tiñeron con safranina y azul de toluidina O. El estudio revela que morfológicamente S. mauritiiformis y S. yapa se asemejan en que son palmas altas, delgadas y esbeltas, la hoja de S. mauritiiformis forma una palma más corta que en las otras dos especies. La forma de la vena principal, en corte transversal, es rectangular en las tres especies. La hástula en las tres especies es acuminada y adaxial. La estructura anatómica foliar de las tres especies es semejante con algunas diferencias. La lámina tiene las epidermis adaxial y abaxial uniestratificada y en vista superficial tienen las paredes anticlinales rectas; los estomas son intercostales, de tipo tetracítico, presentes en ambas superficies en S. yapa y S. mexicana y sólo en la superficie abaxial en S. mauritiiformis. La hipodermis es de un estrato en S. yapa y S. mexicana y de dos en S. mauritiiformis. En las tres especies el parénquima en empalizada se forma por varios estratos no bien definidos debido a que la forma y el tamaño de las células son similares a las del parénquima esponjoso y, por ello, no se nota una clara delimitación entre ambos. Distribuidos entre la hipodermis y el parénquima en empalizada están los haces fibrosos y los haces vasculares, hacia la

    .9%, 109/644), and low-engaged users (3%, 19/644). Analysis of the research question showed statistically significant differences among user types across all six dimensions of eHEALS-E. Most notably, core relational users performed worse than lurkers on the validating information dimension (P=.01) and worse than active help-seekers on the being smart on the Net dimension (P=.05). Active help-seekers have the highest scores in all dimensions of the eHEALS-E, whereas low-engaged users have statistically significantly lower scores on all dimensions of the eHEALS-E in comparison with the other groups. Those who are looking for advice and support in OHCs by making queries are well equipped with eHealth literacy skills to filter potential misinformation and detect bad advice. However, core relational users (who produce the most content in OHCs) have less-developed skills for cross-validating the information obtained and navigating successfully through the perils of the online world. Site managers should monitor their activity to avoid the spread of misinformation that might lead to unhealthy practices. ©Gregor Petrič, Sara Atanasova, Tanja Kamin.

  17. Second review meeting of the Contracting Parties to the Convention on Nuclear Safety

    Rafferty, Barbara

    2002-01-01

    The Second Review Meeting of the Contracting Parties to the Convention on Nuclear Safety was held in the Headquarters of the International Atomic Energy Agency in Vienna from 15-26 April 2002, under the chairmanship of the President, Mr Miroslav Gregoric, Director of the Slovenian Nuclear Safety Authority. The Convention on Nuclear Safety entered into force in October 1996, has been signed by sixty-five States and ratified by fifty-four, bringing within its scope 428 of the 448 nuclear reactors worldwide. The Convention aims to achieve and maintain a high level of nuclear safety worldwide, through inter alia enhancement of national measures and international co-operation. Obligations on Contracting Parties in accordance with the Convention include: the establishment and maintenance of a legislative and regulatory framework to govern the safety of land-based civil nuclear installations; the allocation of adequate financial and human resources to support the safety objectives; ensuring that all reasonably practicable improvements to safety are made as a matter of urgency. Adherence to this Convention entails two basic commitments by each Contracting Party: to prepare and make available a national report for review; and to subject its national report to a peer review by the other Contracting Parties. Thus, being a Contracting Party to this Convention involves: including in the national report a self-assessment of steps and measures already taken and in progress to implement the Convention obligations; taking an active part in an open and transparent review of its national report and the Reports of other Contracting Parties; and a commitment to a continuous learning and improving process, something which is a key element of a strong safety culture. The peer review of national reports takes place every three years, the first having been held in 1999. The Second Review Meeting was attended by delegates from 46 contracting parties. During the review certain issues were

    framework model are interpreted seismic lines, 3d-models can be generated either in time or in depth domain. Some partners will build their 3d-model in time domain and convert it after finishing to depth. Other participants will transform seismic information first and will model directly in depth domain. To ensure comparability between the different parts transnational velocity models for time-depth conversion are required at an early stage of the project. The exchange of model geometries, topology, and geo-scientific content will be achieved applying an appropriate cyberinfrastructure called GST. It provides functionalities to ensure semantic and technical interoperability. Within the project GeoMol a web server for the dissemination of 3d geological models will be implemented including an administrative interface for the role-based access, real-time transformation of country-specific coordinate systems and a web visualisation features. The project GeoMol is co-funded by the Alpine Space Program as part of the European Territorial Cooperation 2007-2013. The project integrates partners from Austria, France, Germany, Italy, Slovenia and Switzerland and runs from September 2012 to June 2015. Further information on www.geomol.eu.

  19. Proceedings of a workshop on American Eel passage technologies

    Haro, Alexander J.

    2013-01-01

    Recent concerns regarding a decline in recruitment of American eels (Anguilla rostrata) have prompted efforts to restore this species to historic habitats by providing passage for both upstream migrant juveniles and downstream migrant adults at riverine barriers, including low-head and hydroelectric dams (Castonguay et al. 1994, Haro et al. 2000). These efforts include development of management plans and stock assessment reviews in both the US and Canada (COSEWIC 2006, Canadian Eel Working Group 2009, DFO 2010, MacGregor et al. 2010, ASMFC 2000, ASMFC 2006, ASMFC 2008, Williams and Threader 2007), which target improvement of upstream and downstream passage for eels, as well as identification and prioritization of research needs for development of new and more effective passage technologies for American eels. Traditional upstream fish passage structures, such as fishways and fish lifts, are often ineffective passing juvenile eels, and specialized passage structures for this species are needed. Although designs for such passage structures are available and diverse (Knights and White 1998, Porcher 2002, FAO/DVWK 2002, Solomon and Beach 2004a,b, Environment Agency UK 2011), many biologists, managers, and engineers are unfamiliar with eel pass design and operation, or unaware of the technical options available for upstream eel passage, Better coordination is needed to account for eel passage requirements during restoration efforts for other diadromous fish species. Also, appropriately siting eel passes at hydropower projects is critical, and siting can be difficult and complex due to physical restrictions in access to points of natural concentrations of eels, dynamic hydraulics of tailrace areas, and presence of significant competing flows from turbine outfalls or spill. As a result, some constructed eel passes are sited poorly and may pass only a fraction of the number of eels attempting to pass the barrier. When sited and constructed appropriately, however, eel passes

  20. Interannual drivers of the seasonal cycle of CO2 in the Southern Ocean

    L. Gregor

    2018-04-01

    Full Text Available Resolving and understanding the drivers of variability of CO2 in the Southern Ocean and its potential climate feedback is one of the major scientific challenges of the ocean-climate community. Here we use a regional approach on empirical estimates of pCO2 to understand the role that seasonal variability has in long-term CO2 changes in the Southern Ocean. Machine learning has become the preferred empirical modelling tool to interpolate time- and location-restricted ship measurements of pCO2. In this study we use an ensemble of three machine-learning products: support vector regression (SVR and random forest regression (RFR from Gregor et al. (2017, and the self-organising-map feed-forward neural network (SOM-FFN method from Landschützer et al. (2016. The interpolated estimates of ΔpCO2 are separated into nine regions in the Southern Ocean defined by basin (Indian, Pacific, and Atlantic and biomes (as defined by Fay and McKinley, 2014a. The regional approach shows that, while there is good agreement in the overall trend of the products, there are periods and regions where the confidence in estimated ΔpCO2 is low due to disagreement between the products. The regional breakdown of the data highlighted the seasonal decoupling of the modes for summer and winter interannual variability. Winter interannual variability had a longer mode of variability compared to summer, which varied on a 4–6-year timescale. We separate the analysis of the ΔpCO2 and its drivers into summer and winter. We find that understanding the variability of ΔpCO2 and its drivers on shorter timescales is critical to resolving the long-term variability of ΔpCO2. Results show that ΔpCO2 is rarely driven by thermodynamics during winter, but rather by mixing and stratification due to the stronger correlation of ΔpCO2 variability with mixed layer depth. Summer pCO2 variability is consistent with chlorophyll a variability, where higher concentrations of chlorophyll

  3. Archaeological Guidebooks from the Libraries of the Operosi and Their Circle Housed in the Seminary Library in Ljubljana

    Luka Vidmar

    2005-12-01

    Full Text Available Ljubljana's Academia Operosorum, which helped to regenerate scientific, cultural and artistic activities in the Carniola of the late 17th/early 18th century by introducing the influence of Baroque Italy, was deeply interested in researching and understanding the material and spiritual heritage of Roman antiquity. The Operosi believed that the memory of Emona, the ancient predecessor of Ljubljana, promised a successful development of the modern city, since it symbolically connected Ljubljana with the historical and artistic centre of Europe, the city of Rome. On the one hand, such views on the ancient past were reinforced by Carniolan historians of the previous generation, Janez Ludvik Schönleben and Janez Vajkard Valvasor; on the other, they stemmed from their own observation of Roman monuments, based on their journeys to Italy undertaken immediately after their studies or during their service, and on reading specialised books, bought either on these occasions or in Ljubljana. Many of these books are now housed in the Seminary Library in Ljubljana, as several Operosi donated their private libraries to this new public library, which they helped to establish in 1701. Janez Gregor Dolničar (1655-1719, a Ljubljana lawyer and historian, as well as one of the most prominent members of the Academia Operosorum, owned at least three guidebooks to Rome, written by Pietro Martire Felini and Matteo Mayer and containing detailed descriptions of mainly ancient monuments. His private library also included the architectural treatise by Vitruvius and the hydraulic treatise by Frontinus. Moreover, a few chapters of Dolničar's book on the history of Trieste, written by Father Ireneo della Croce, are devoted to the monuments of ancient Tergeste. Janez Anton Dolničar (1662-1714, the Dean of Ljubljana's Cathedral, owned a guide to Naples, written by Giuseppe Mormile and dealing mostly with ancient ruins in the countryside.

    The 186 papers in this volume constitute the proceedings of the fifth Science of Making Torque from Wind conference, which is organized by the European Academy of Wind Energy (EAWE, www.eawe.eu). The conference, also called Torque 2014, is held at the Technical University of Denmark (DTU) 17-20 June 2014. The EAWE conference series started in 2004 in Delft, the Netherlands. In 2007 it was held in Copenhagen, in 2010 in Heraklion, Greece, and then in 2012 in Oldenburg, Germany. The global yearly production of electrical energy by wind turbines has grown approximately by 25% annually over the last couple of decades and covers now 2-3% of the global electrical power consumption. In order to make a significant impact on one of the large challenges of our time, namely global warming, the growth has to continue for a decade or two yet. This in turn requires research and education in wind turbine aerodynamics and wind resources, the two topics which are the main subjects of this conference. Similar to the growth in electrical power production by wind is the growth in scientific papers about wind energy. Over the last decade the number of papers has also grown by about 25% annually, and many research based companies all over the world are founded. Hence, the wind energy research community is rapidly expanding and the Torque conference series offers a good opportunity to meet and exchange ideas. We hope that the Torque 2014 will heighten the quality of the wind energy research, while the participants will enjoy each others company in Copenhagen. Many people have been involved in producing the Torque 2014 proceedings. The work by more than two hundred reviewers ensuring the quality of the papers is greatly appreciated. The timely evaluation and coordination of the reviews would not have been possible without the work of sixteen ''section editors'' all from DTU Wind Energy: Christian Bak, Andreas Bechmann, Ferhat Bingöl, Ebba Dellwik, Nikolay Dimitrov, Gregor Giebel, Martin

Two (5%) of 40 patients with bone sarcoma had an objective response, including one (5%) of 22 patients with osteosarcoma and one (20%) of five patients with chondrosarcoma. None of the 13 patients with Ewing's sarcoma had an objective response. The most frequent grade 3 or worse adverse events were anaemia (six [14%]), decreased lymphocyte count (five [12%]), prolonged activated partial thromboplastin time (four [10%]), and decreased platelet count (three [7%]) in the bone sarcoma group, and anaemia, decreased lymphocyte count, and prolonged activated partial thromboplastin time in the soft-tissue sarcoma group (three [7%] each). Nine (11%) patients (five [12%] in the bone sarcoma group and four [10%] in the soft-tissue sarcoma group) had treatment-emergent serious adverse events (SAEs), five of whom had immune-related SAEs, including two with adrenal insufficiency, two with pneumonitis, and one with nephritis. The primary endpoint of overall response was not met for either cohort. However, pembrolizumab showed encouraging activity in patients with undifferentiated pleomorphic sarcoma or dedifferentiated liposarcoma. Enrolment to expanded cohorts of those subtypes is ongoing to confirm and characterise the activity of pembrolizumab.

    nuclei of oculomotor and facial nerves. In case 4 there were occipitalization of atlas and Chiari deformity. In case 5 vertebral reduction in the cervical region was evidenced but bony coalescence could not be proved. In the last four cases the constitutional morphologic type was determined. Electroencephalograms of cases 3, 4 and 5 showed no abnormalities; in case 1 slow bilateral occipital waves were recorded. The authors call attention to the importance of the diagnosis of these anomalies susceptible of successful surgical correction, which can simulate many nervous diseases of untoward course, like lateral amyotrophic sclerosis, syringomyelia (which can be actually associated to the bony anomaly, as in case 2, sclerosis of dorsal funiculi of the spinal cord, tabes, multiple sclerosis, heredocerebellar ataxia, etc. The authors also stress the clinico-radiological differences between basilar impression and platybasia, frequently taken as synonyms. Although both anomalies may coexist (as in cases 4 and 5 their association is not an absolute rule; on the contrary, in case 2 the basal angle was in the inferior limit of normality and in case 3 it was much lower. Emphasis is put on the value of the Chamberlain's line and chiefly in the McGregor basal line for the correct diagnosis of basilar invagination of the occipital bone.

    As part of the effort to build quantitative models of glacial erosion and sedimentation, it is particularly important to construct scaled relations between erosion, transport, and sedimentation rates and appropriate glaciological variables (e.g., ice velocity). Recent acquisition of bed topography and ice velocity data for the marine West Antarctic Ice Sheet (WAIS)[Joughin et al., 1999; Lythe et al., in press] provides an unprecedented opportunity to investigate continental-scale patterns of glacial erosion and their relationship to the ice velocity field. Utilizing this data, we construct a map of estimated long-term erosion rates beneath the WAIS. In order to calculate long-term erosion rates from the available data, we assume that: (1) the ice sheet has been present for ~5 mill. years, (2) the initial topography beneath the WAIS was that of a typical ( ~200 m.b.s.l.) continental shelf, and (3) the present topography is near local isostatic equilibrium (Airy type). The map of long-term erosion rates constructed in this fashion shows an intriguing pattern of relatively high rates (of the order of 0.1 mm/yr) concentrated beneath modern ice stream tributaries (ice velocity ~100 m/yr), but much lower erosion rates (of the order of 0.01 mm/yr) beneath both the modern fast-moving ice streams ( ~400 m/yr.) and the slow-moving parts of the ice sheet ( ~10 m/yr). This lack of clear correlation between the estimated erosion rates and ice velocity is somewhat unexpected given that both observational and theoretical studies have shown that bedrock erosion rates beneath mountain glaciers can often be calculated by multiplying the basal sliding velocity by a constant (typically of the order of ~10^-4)(Humphrey and Raymond, 1993 and Mac Gregor et al., 2000). We obtain an improved match between estimated erosion rates and bed topography by calculating erosion rates using horizontal gradients within the ice velocity field rather than the magnitude of ice velocity, as consistent

  9. The Universal Cpx Jd-Di barometer for mantle peridotite eclogite and pyroxenites and it using for the mantle petrology

    Ashchepkov, Igor

    2015-04-01

    The Jd-Di exchange in clinopyroxenes used for the calibration of pyroxene barometer (Ashchepkov, 2000;2002; Ashchepkov et al 2010;2011;2012) was transformed to make one universal equation for mantle peridotite eclogites and pyroxenites. The original barometer (Ashchepkov, 2002) calibrated on pressures produced by Opx barometry (McGregor , 1974) was transformed (Ashchepkov et al ., 2004; 2010; 2011) to satisfy the increasing data bases for the mantle xenoliths and experimental values 530 in peridotitic and 650 in elcogitic systems . The obtained difference Pd =Pcpx- Pexp were studied for the dependence on each component and their combination . Instead of the common activities we used the temperature-dependent empirical equations. The three separate equations for the common peridotites, pyroxenites and eclogites (Ashchepkov et al., 2010) were checked and complex To and Al-Na-Fe dependent universal coefficients were received. The KD is determined as follows: KD=Na/AlCr*Mg/Ca The logarithmic dependence between P and KD was transformed to a linear one. Final pressure equations are: AlCr=(Al-0.01) *((T-600)/700)**0.75+Cr*(ToK-100)/1000+(4*Ti-0.0125)/ (T0-801)*650 +0.55*((Fe-0.23) *(T0-900)/10000-K) P=0.26*(5+12*(Al+0.30*Na)KD* ToK**0.75 /(1+Fe+ Fe*(ToK-600)/1000)-ln(1273/ ToK))*40*(7*Na-Al-15*Ti+10*Cr+Mg/4)+7.5*Si-20*( Al*Na*Mg/Ca/(Al-2*Ti+Na-2*Fe/(Fe+Mg))+50*(Na+0.1*Al-2*Ti+0.05*Mg-0.22*Ca-0.7*Na)/Ca). Obtained equation in combination with the (Nimis,Taylor, 2000) thermometer allow to reconstruct position of the magma feeder systems of the alkali basaltic magma withing the mantle diapirs in modern platforms like in Vitim plateau (Ashchepkov et al., 2011) and now was applicated to reconstruct the deep seated magma conduits beneath the mountain collision systems, island arcs ocean plateaus etc. This equation allows to receive the positions of the major groups of eclogites mantle sections and to find out the regularities of their behavior.

    any successful inversion, whereas the other three papers discuss novel inversion techniques for specific applications. In the first contribution, with the title A Novel Simplified Mathematical Model for Antennas used in Medical Imaging Applications, the authors M J Fernando, M Elsdon, K Busawon and D Smith discuss a new technique for modelling the current across a monopole antenna from which the radiation fields of the antenna can be calculated very efficiently in specific medical imaging applications. This new technique is then tested on two examples, a quarter wavelength and a three quarter wavelength monopole antenna. The next contribution, with the title An investigation into the use of a mixture model for simulating the electrical properties of soil with varying effective saturation levels for sub-soil imaging using ECT by R R Hayes, P A Newill, F J W Podd, T A York, B D Grieve and O Dorn, considers the development of a new visualization tool for monitoring soil moisture content surrounding certain seed breeder plants. An electrical capacitance tomography technique is employed for verifying how efficiently each plant utilises the water and nutrients available in the surrounding soil. The goal of this study is to help in developing and identifying new drought tolerant food crops. In the third contribution Combination of Maximin and Kriging Prediction Methods for Eddy-Current Testing Database Generation by S Bilicz, M Lambert, E Vazquez and S Gyimóthy, a novel database generation technique is proposed for its use in solving inverse eddy-current testing problems. For avoiding expensive repeated forward simulations during the creation of this database, a kriging interpolation technique is employed for filling uniformly the data output space with sample points. Mathematically this is achieved by using a maximin formalism. The paper 2.5D inversion of CSEM data in a vertically anisotropic earth by C Ramananjaona and L MacGregor considers controlled

They allow to work with the wide range of the pyroxenite compositions giving the practically coinciding PT parameters with the pressures determined for ilmenites and chromites as well as the (Brey, Kohler, 1900) pressure estimates. The PT parameters reconstructed for the mantle lithosphere beneath > 120 pipes from Yakutia , Baltica, Africa , North America and other world wide kimberlites have shown very good coincidence with the estimates from the other methods of monomineral (Nimis, Taylor, 2000; McGregor, 1974; Ashchepkov ea. 2009 ) and Gar-Opx barometers (Brey, Kohler, 1900; Nickel, Green, 1975). For the garnet and spinel xenoliths of the alkali basalts representing fertile or regenerated peridotites with high Al content of the clinopyroxenes the modified equation allows to determine the pressures together for megacrysts, pyroxeniets and peridotites using the following equation P=0.035*Kd*ToK)/(1+3.5*Fe)- 50*ln(1273/(ToK-100)*(Al+5*Na-Ti+2*Cr) -(Na-0.050)*(ToK-1200)*(Ca-0.85)/7000+5 Where KD = Na*Mg/xAlCr*/Ca; xAlCr= (Al+Si-2)*((ToK-700)/900)^0.35+Cr+Fe3-K +(4*Ti-0.0125)/(ToK-600)*700 +(Fe-0.21)*(ToK-400)/17000 This equations also very good reproduce the experimental runs in the pressure interval from 10 to 80 kbar but better to 50 kbars (R=0.92) (S=5) for 170 experimental runs (Putirka ea, 1996; Fallon ea, 1999; Taylor ea, 1998; Drapper Green

The international conference responded to the urgent need of advancing our understanding of the complex climate system and development of adequate measures for saving the planet from environmental disaster. It also fits well with the Republic of South African government's major political decision to include the responses to global change/climate change at the very top of science and technology policy. The conference participants are grateful to the Norway Research Council and the National Research Foundation (NRF) RSA who supported the Conference through the project "Analysis and Possibility for Control of Atmospheric Boundary Layer Processes to Facilitate Adaptation to Environmental Changes" realized in the framework of the Programme for Research and Co-operation Phase II between the two countries.

    , giving a really excellent set of presentations. Finally we are also pleased to express our thanks to the Conference Office of the Institute of Physics for their invaluable support in organising this event. We are especially grateful to Dawn Stewart for her responsive and efficient day-to-day handling of this event, as well as to Claire Garland for her planning and management of this event. This conference is the second in a series of conferences that began with the Rutherford Jubilee Conference held in Manchester in 1961, which is described in one of the contributions to these proceedings. I do hope that at least some of the delegates from the Centennial Conference will be able to attend the next one, fifty years hence in 2061, just as we were honoured to have some of the Jubilee delegates with us for the Centennial. If I am still around, I doubt that I will have the energy then to be conference chair. I would also not like to attempt to predict the plenary programme, but I hope that it will be as vibrant and exciting as the 2011 conference.

    service management' by Gregor v Bochmann and Abdelhakim Hafid offers lessons in QoS management learned during the implementation of a prototype News-on-Demand application. Some general principles are extracted from this experience. In particular, a novel QoS adaptation technique is highlighted: transparent automatic reconfiguration of the components involved in a communication (e.g. choice of an alternative network or server at run time). An algorithm which attempts to choose optimal configurations is discussed. `Quality of service management using generic modelling and monitoring techniques', by Leonard Franken and Boudewijn Haverkort investigates the use of Petri nets as the basis of generic QoS monitoring of distributed applications. A distributed application is exploded into finegrained component parts and interactions between these parts are instrumented. The paper offers a case study of the instrumentation of a videophone application using this technique. Simulation is used to evaluate the scheme. The final two papers in the special issue are more focused and pragmatic in nature. These papers explore QoS provision in particular environments (the World Wide Web and ATM networks respectively) through reported implementation experience. `QoS management in a World Wide Web environment which supports continuous media' by Michael Fry, Aruna Seneviratne, Andreas Vogel and Varuni Witana looks at the practical provision of end to end QoS management in the World Wide Web. The paper looks beyond currently available tools such as RealAudio and StreamWorks and presents a QoS managed RTP based solution featuring an adjunct QoS management protocol. This work offers QoS management functions (e.g. QoS negotiation, adaptation and control of QoS degradation paths) directly to the user via the usual Web GUI. `A QoS adaptive multimedia transport system: design, implementation and experiences' by Andrew Campbell and Geoff Coulson offers further practical experience of QoS management

    , etc. It requires a change in the way that faculty and students view themselves (4). It is clear that this course model is an example of one that replaces the traditional model of passive learners and inspired lecturers by a model where the students take an active and responsible part in the learning process and faculty members facilitate learning by preparing a learning environment that will challenge and empower students. These changes are fundamental and represent new traditions that guide students and faculty into a new approach to education. It is important to extend such approaches to other upper-level courses in the chemistry curriculum. Acknowledgment This work was supported by the National Science Foundation under grant 94-50615.

    Freidrich, Sean Thomas, Gregor Krings, Michael Lopez, Marena Trinidad, Barbara Panning, Al Burlingame University of California, San Francisco, CA, USA SOX2 is a versatile transcription factor that maintains embryonic stem cell (ESC) pluripotency and self-renewal, and is important for proper lineage specification and adult stem cell maintenance. This versatility is likely due to post-translational modifications (PTMs) as SOX2 has been reported to be modified by numerous chemical moieties in a variety of cell types. One such PTM is O-GlcNAc, the dynamic and regulatory glycosylation of intracellular proteins. Global O-GlcNAc is essential for ESC self-renewal though the function of SOX2 O-GlcNAcylation in ESC is not understood. Here, we show that SOX2 is O-GlcNAc modified in the transactivation domain and alterations of self-renewing signals induce changes in SOX2 O-GlcNAc stoichiometry. Replacement of wild-type SOX2 with an O-GlcNAc-deficient mutant SOX2 in ESCs increases the pluripotency transcriptional network while down-regulating genes involved in differentiation. Analysis of SOX2-interacting proteins from ESCs revealed that the WT and mutant SOX2 interact with distinct subsets of transcriptional regulatory complexes. Thus, SOX2 O-GlcNAcylation modulates the transcriptional landscape of ESCs by modulating SOX2 activity and interactions with epigenetic regulatory complexes.
