  3. Jacobus Schroeder van der Kolk (1797-1862): his resistance against materialism.

    Science.gov (United States)

    Eling, P

    1998-07-01

    Schroeder van der Kolk is regarded as the founder of Dutch psychiatry and neurology. This paper describes his vitalistic views on the relation between body and soul, as formulated by him in a series of lectures. These lectures were intended to counteract the materialistic tendencies of some of Schroeder van der Kolk's French and German contemporaries. It is argued that Schroeder van der Kolk can be regarded as the transition in Holland from the "Naturphilosophie" approach to the modern experimental approach in physiology.

  7. The Schroeder functional equation and its relation to the invariant measures of chaotic maps

    International Nuclear Information System (INIS)

    Luevano, Jose-Ruben; Pina, Eduardo

    2008-01-01

    The aim of this paper is to show that the invariant measure for a class of one-dimensional chaotic maps, T(x), is an extended solution of the Schroeder functional equation, q(T(x)) = λq(x), induced by them. Hence, we give a unified treatment of a collection of exactly solved examples worked out in the current literature. In particular, we show that these examples belong to a class of functions introduced by Mira (see the text). Moreover, as a new example, we compute the invariant densities for a class of rational maps having the Weierstrass p function as an invariant one. Also, we study the relation between that equation and the well-known Frobenius-Perron and Koopman's operators

    This book explores the life and scientific legacy of Manfred Schroeder through personal reflections, scientific essays, and Schroeder’s own memoirs. Reflecting the wide range of Schroeder’s activities, the first part of the book contains thirteen articles written by his colleagues and former students. Topics discussed include his early, pioneering contributions to the understanding of statistical room acoustics and to the measurement of reverberation time; his introduction of digital signal processing methods into acoustics; his use of ray tracing methods to study sound decay in rooms; and his achievements in echo and feedback suppression and in noise reduction. Other chapters cover his seminal research in speech processing including the use of predictive coding to reduce audio bandwidth which led to various code-excited linear prediction schemes, today used extensively for speech coding. Several chapters discuss Schroeder’s work in low-peak factor signals, number theory, and maximum-length sequences wi...

  9. SOUND FIELD DIFFUSIVITY AT THE TOP SURFACE OF SCHROEDER DIFFUSER BARRIERS

    2006-10-01

    Full Text Available Reactive barriers are one of the most promising and novel environmental noise barriers. In this case using Schroeder diffusers (e.g. quadratic residue diffusers on the top surface of the T-shape barrier was shown to significantly improve the performance of absorbent T-shape barriers. The reasons behind the high performance of diffuser barriers are considered in this investigation. A question about the diffusivity behavior of Schroeder diffusers when they are utilized on the top of barrier was raised. Diffusion coefficients of a diffuser in different conditions at some receiver locations were predicted by using a 2D boundary element method. It was found that the diffusion coefficient of diffuser at the top of barrier is so small that the diffusivity of the structure is almost the same as rigid T-shape barrier. To find the barrier’s cap behavior, the total field above the top surface of profile barriers was also predicted. It was found that the lowest total energy is at the receiver side of the cap very close to the top surface,which could demonstrate the effect of top surface on absorbing the energy as wave transfers from source edge toward the receiver side of the cap. In this case the amount of minimum total energy depends on the frequency and the configuration of the top surface. A comparison between the reductions of total field at the source side of the cap with the improvements of barrier’s performance was also done. It was shown that the amount of decrease in total field compared to that of an absorbent barrier “Ref” is directly associated to the amount of improvement in the insertion loss made by the diffuser barrier compared to the “Ref” barrier in the wide area on the ground at the shadow zone. Finally it was concluded that the diffuser on the top of barrier does not act as a diffuser and a kind of similarity between the contribution of diffuser and absorbent material on the top of T-profile barrier is seen.

  10. Estimation of Alcohol Concentration of Red Wine Based on Cole-Cole Plot

    Science.gov (United States)

    Watanabe, Kota; Taka, Yoshinori; Fujiwara, Osamu

    To evaluate the quality of wine, we previously measured the complex relative permittivity of wine in the frequency range from 10 MHz to 6 GHz with a network analyzer, and suggested a possibility that the maturity and alcohol concentration of wine can simultaneously be estimated from the Cole-Cole plot. Although the absolute accuracy has not been examined yet, this method will enable one to estimate the alcohol concentration of alcoholic beverages without any distillation equipment simply. In this study, to investigate the estimation accuracy of the alcohol concentration of wine by its Cole-Cole plots, we measured the complex relative permittivity of pure water and diluted ethanol solution from 100 MHz to 40 GHz, and obtained the dependence of the Cole-Cole plot parameters on alcohol concentration and temperature. By using these results as calibration data, we estimated the alcohol concentration of red wine from the Cole-Cole plots, which was compared with the measured one based on a distillation method. As a result, we have confirmed that the estimated alcohol concentration of red wine agrees with the measured results in an absolute error by less than 1 %.

    2009-01-01

    In order to evaluate the quality of red wine, measurement of the complex relative permittivity was conducted in the frequency range from 100 MHz to 40 GHz with a network analyzer. Results showed that the Cole-Cole plot of red wine consists of a semicircle at frequencies above 1 GHz and a straight line at frequencies below 1 GHz, which come from the dispersion properties for the water solution of alcohol and ingredients peculiar to red wine, respectively. Based on the Cole-Cole plots measured for seven kinds of red wines made from the same brand of Merlot in different production years, we estimated Debye dispersion parameters to reveal that the alcohol concentration and ingredient property can simultaneously be evaluated from the parameters for the semicircle and straight line, respectively.

    Full Text Available The Caribbean skate Dipturus teevani (Bigelow & Schroeder, 1951 is recorded for the first time from Brazilian waters. The specimen was collected in the continental slope off Bahia State. With this record, four species of Dipturus Rafinesque, 1810 are known from Brazil: D. chilensis (Guichenot, 1848, D. leptocauda (Kreft & Stehmann, 1975, D. trachyderma (Krefft & Stehmann, 1975 and D. teevani (Bigelow & Schroeder, 1951. They are typical inhabitants of deep waters between the outer shelf edge (195-200m and the slope (more than 500m. Although morphologically conservative, the species of Dipturus can be distinguished from each other by the number of dorsal and nuchal thorns, the number of caudal thorns, dorsal and ventral spinulation and specific total length. An identification key for the species of Dipturus recorded from Brazil is presented.

    2017-12-01

    The application of time-domain induced polarization (TDIP) is increasing with advances in acquisition techniques, data processing and spectral inversion schemes. An inversion of TDIP data for the spectral Cole-Cole parameters is a non-linear problem, but by applying a 1-D Markov Chain Monte Carlo (MCMC) inversion algorithm, a full non-linear uncertainty analysis of the parameters and the parameter correlations can be accessed. This is essential to understand to what degree the spectral Cole-Cole parameters can be resolved from TDIP data. MCMC inversions of synthetic TDIP data, which show bell-shaped probability distributions with a single maximum, show that the Cole-Cole parameters can be resolved from TDIP data if an acquisition range above two decades in time is applied. Linear correlations between the Cole-Cole parameters are observed and by decreasing the acquisitions ranges, the correlations increase and become non-linear. It is further investigated how waveform and parameter values influence the resolution of the Cole-Cole parameters. A limiting factor is the value of the frequency exponent, C. As C decreases, the resolution of all the Cole-Cole parameters decreases and the results become increasingly non-linear. While the values of the time constant, τ, must be in the acquisition range to resolve the parameters well, the choice between a 50 per cent and a 100 per cent duty cycle for the current injection does not have an influence on the parameter resolution. The limits of resolution and linearity are also studied in a comparison between the MCMC and a linearized gradient-based inversion approach. The two methods are consistent for resolved models, but the linearized approach tends to underestimate the uncertainties for poorly resolved parameters due to the corresponding non-linear features. Finally, an MCMC inversion of 1-D field data verifies that spectral Cole-Cole parameters can also be resolved from TD field measurements.

    Cole disease is a genodermatosis of pigmentation following a strict dominant mode of inheritance. In this study, we investigated eight patients affected with an overlapping genodermatosis after recessive inheritance. The patients presented with hypo- and hyperpigmented macules over the body, resembling dyschromatosis universalis hereditaria in addition to punctuate palmoplantar keratosis. By homozygosity mapping and whole-exome sequencing, a biallelic p.Cys120Arg mutation in ectonucleotide pyrophosphatase/phosphodiesterase 1 (ENPP1) was identified in all patients. We found that this mutation, like those causing dominant Cole disease, impairs homodimerization of the ENPP1 enzyme that is mediated by its two somatomedin-B-like domains. Histological analysis revealed structural and molecular changes in affected skin that were likely to originate from defective melanocytes because keratinocytes do not express ENPP1. Consistently, RNA-sequencing analysis of patient-derived primary melanocytes revealed alterations in melanocyte development and in pigmentation signaling pathways. We therefore conclude that germline ENPP1 cysteine-specific mutations, primarily affecting the melanocyte lineage, cause a clinical spectrum of dyschromatosis, in which the p.Cys120Arg allele represents a recessive and more severe form of Cole disease.

    The coexistence of abnormal keratinization and aberrant pigmentation in a number of cornification disorders has long suggested a mechanistic link between these two processes. Here, we deciphered the genetic basis of Cole disease, a rare autosomal-dominant genodermatosis featuring punctate keratoderma, patchy hypopigmentation, and uncommonly, cutaneous calcifications. Using a combination of exome and direct sequencing, we showed complete cosegregation of the disease phenotype with three heterozygous ENPP1 mutations in three unrelated families. All mutations were found to affect cysteine residues in the somatomedin-B-like 2 (SMB2) domain in the encoded protein, which has been implicated in insulin signaling. ENPP1 encodes ectonucleotide pyrophosphatase/phosphodiesterase 1 (ENPP1), which is responsible for the generation of inorganic pyrophosphate, a natural inhibitor of mineralization. Previously, biallelic mutations in ENPP1 were shown to underlie a number of recessive conditions characterized by ectopic calcification, thus providing evidence of profound phenotypic heterogeneity in ENPP1-associated genetic diseases.

    Hybrid ColE1 plasmids called ColE1-cos lambda-guaA or ColE1-cos lambda-gal can be efficiently transduced into various E.coli K-12 cells through packaging into lambda phage particles. Using these plasmids, repair of ultraviolet-light (UV) damaged ColE1 DNAs was studied in various UV sensitive E.coli K-12 mutants. The host mutations uvrA and uvrB markedly reduced host-cell reactivation of UV-irradiated ColE1-cos lambda-guaA. Pre-existing hybrid ColE1 plasmids had no effect on the frequency of lambda phage-mediated transduction of another differentially marked hybrid ColE1 DNAs. ColE1-cos lambda-guaA and ColE1-cos lambda-gal DNAs could temporarily but not stably co-exist in E.coli K-12 recA cells. The presence of ColE1-cos lambda-gal in uvrB cells promoted the repair of super-infected UV-irradiated ColE1-cos lambda-guaA about 7-fold. The same ColE1-cos lambda-gal plasmid in a uvrB recA double mutant did not have this promoting effect. These results indicate that the effect of resident hybrid ColE1 plasmids is manifested by the host recA + gene function(s) and suggest that ColE1 plasmit itself provides no recA + -like functions.

  10. Improved Cole parameter extraction based on the least absolute deviation method

    The Cole function is widely used in bioimpedance spectroscopy (BIS) applications. Fitting the measured BIS data onto the model and then extracting the Cole parameters (R 0 , R ∞ , α and τ) is a common practice. Accurate extraction of the Cole parameters from the measured BIS data has great significance for evaluating the physiological or pathological status of biological tissue. The traditional least-squares (LS)-based curve fitting method for Cole parameter extraction is often sensitive to noise or outliers and becomes non-robust. This paper proposes an improved Cole parameter extraction based on the least absolute deviation (LAD) method. Comprehensive simulation experiments are carried out and the performances of the LAD method are compared with those of the LS method under the conditions of outliers, random noises and both disturbances. The proposed LAD method exhibits much better robustness under all circumstances, which demonstrates that the LAD method is deserving as an improved alternative to the LS method for Cole parameter extraction for its robustness to outliers and noises.

    DNA fragments obtained from EcoRI endonuclease digestion of bacteriophage ϕ80pt190 (trp+) and the plasmid ColE1 were covalently joined with polynucleotide ligase. Transformation of Escherichia coli trp- strains to tryptophan independence with the recombined DNA selected for reconstituted ColE1 plasmids containing the tryptophan operon and the ϕ80 immunity region. Similarly, an EcoRI endonuclease generated fragment of plasmid pSC105 DNA containing the genetic determinant of kanamycin resistance was inserted into the ColE1 plasmid and recovered in E. coli. The plasmids containing the trp operon (ColE1-trp) and the kanamycin resistance gene were maintained under logarithmic growth conditions at a level of 25-30 copies per cell and accumulate to the extent of several hundred copies per cell in the presence of chloramphenicol. Cells carrying the ColE1-trp plasmid determined the production of highly elevated levels of trp operon-specific mRNA and tryptophan biosynthetic enzymes. Images PMID:4610576

  18. A comparative study of PCA, SIMCA and Cole model for classification of bioimpedance spectroscopy measurements.

    Science.gov (United States)

    Nejadgholi, Isar; Bolic, Miodrag

    2015-08-01

    Due to safety and low cost of bioimpedance spectroscopy (BIS), classification of BIS can be potentially a preferred way of detecting changes in living tissues. However, for longitudinal datasets linear classifiers fail to classify conventional Cole parameters extracted from BIS measurements because of their high variability. In some applications, linear classification based on Principal Component Analysis (PCA) has shown more accurate results. Yet, these methods have not been established for BIS classification, since PCA features have neither been investigated in combination with other classifiers nor have been compared to conventional Cole features in benchmark classification tasks. In this work, PCA and Cole features are compared in three synthesized benchmark classification tasks which are expected to be detected by BIS. These three tasks are classification of before and after geometry change, relative composition change and blood perfusion in a cylindrical organ. Our results show that in all tasks the features extracted by PCA are more discriminant than Cole parameters. Moreover, a pilot study was done on a longitudinal arm BIS dataset including eight subjects and three arm positions. The goal of the study was to compare different methods in arm position classification which includes all three synthesized changes mentioned above. Our comparative study on various classification methods shows that the best classification accuracy is obtained when PCA features are classified by a K-Nearest Neighbors (KNN) classifier. The results of this work suggest that PCA+KNN is a promising method to be considered for classification of BIS datasets that deal with subject and time variability. Copyright © 2015 Elsevier Ltd.

    L'enseignement des sciences de la nature tient-il une place suffisante à l'école maternelle et élémentaire ? Toutes les enquêtes montrent que tel n'est pas le cas, en France, aujourd'hui. Pourtant, est-il rien qui suscite davantage émerveillement, curiosité, expérimentation, apprentissage du langage et de l'argumentation, tous éléments fondamentaux du développement de l'enfant ? Mais est-il possible d'enseigner ces sciences si compliquées à des enfants de 5 à 12 ans ? La réponse est oui ! A destination des professeurs d'école (institutrices et instituteurs) comme des parents d'élèves qui sont leurs partenaires, ce livre énonce quelques règles, principes et exemples concrets pouvant guider chacun dans sa pratique quotidienne.

Propõe um estudo exploratório para viabilizar essa correspondência a partir de oito obras escolhidas de autores europeus do século XIX, a maioria bibliófilos reconhecidos, a saber: Peignot (1823, Namur (1834, Hesse (1841, Rouveyre (1878, Richard (1883, Gräsel (1893, Petzholdt (1894 e Maire (1896. Essas obras serão analisadas a partir de três categorias contemporâneas da área: desenvolvimento de coleções, seleção e aquisição, por meio do método de revisão de literatura. Conclui-se, por fim, que o fenômeno da explosão da informação afeta o processo de desenvolvimento de coleções como um todo desde o século XVIII. Os autores do século XIX selecionados para o estudo apresentaram várias soluções - as quais fortaleceram o que hoje é denominado de abordagem baseada no acesso à informação - para lidar com a complexidade gerada pelo fenômeno da explosão da informação.

    2009-01-01

    Uranium mining has not been very active in much of the world for the past 30 years. With the nuclear renaissance, the uranium mining industry has undergone a renaissance as well. There are a handful of uranium mining companies that have been operating since the last uranium boom that are taking forward thinking approaches and retrofitting their businesses to approach mining in a more sustainable manner. However, with the nuclear renaissance, there are hundreds of juniors in the mix that are ripe for implementing sustainable practices in their operations from the beginning. The Coles Hill uranium deposit site in Pittsylvania County is on land that has been owned by the families living there for generations (some as far back as the 1780's). Virginia Uranium Inc. (VUI) owns the Coles Hill uranium deposit. Concern for the community's progress and respect for the environment are deeply ingrained in VUI values. VUI's business decisions are guided by their core values which are expressed in seven guiding principles. This paper will present an initial approach to sustainability that is incorporated into a company's operations from its inception, an approach that is the only option from the perspective of the owners of VUI.

    Full Text Available Contrairement à de nombreux pays (Brésil, Russie…, en France l’université ne dispose pas d’un quasi monopole sur la formation des journalistes. Les écoles privées se partagent avec l’université la maîtrise des écoles d’apprentissage du métier. A partir de 1976, une Commission paritaire pour l’emploi des journalistes (CPNEJ a disposé d’un mandat pour distribuer des agréments au nom de la profession et ainsi différencier des écoles « reconnues » des « non reconnues ». Les archives de la CPNEJ montrent que les critères de reconnaissance ont été élaborés à partir des modèles de formation déjà existants, en particulier ceux du Centre de formation des journalistes (CFJ et de l’Ecole supérieure de journalisme de Lille (ESJ Lille, qui figurent parmi les plus anciennes écoles privées de journalisme en France. La politique de limitation du nombre d’écoles agréées, qui vise à protéger les écoles déjà établies, est l’objet de tensions entre les différentes parties syndicales. Lorsque sa neutralité est remise en cause, cette Commission cherche à renforcer sa qualité d’expertise dans le secteur de la formation et ainsi à garantir aux écoles dominantes le maintien de leur domination symbolique. La profession fait ainsi face à l’émergence de modèles de formations concurrents qui se multiplient à la fois à l’Universitéet dans des écoles privées échappant à une surveillance paritaire, et qui dans les deux cas sont donc moins contrôlées par les syndicats de la corporation. Cette Commission a formalisé de multiples normes visant à conserver un relatif contrôle sur ses formations et ainsi maintenir des « écoles de journalisme » qui conservent des logiques propres à la fois en terme de transmission d’une certaine éthique professionnelle mais aussi de savoir-faire techniques propres au milieu. En même temps, la subjectivité des critères de reconnaissance offre la possibilit

Nous présentons les "portraits orthographiques" de quatre élèves à travers l'analyse de l'évolution de leurs compétences en situation de dictée (sur deux ans et de production écrite (sur une année scolaire. Nous élargissons ensuite aux productions des CM2 lors des évaluations nationales. Nous montrons que ces élèves ont des évolutions similaires mais assez fortement décalées dans le temps. C'est la maîtrise de procédures morphosyntaxiques (qui coexistent alors avec les procédures morphosémantiques développées en premier lieu qui permet d'améliorer puis stabiliser leurs choix orthographiques. L'accord sujet-verbe reste cependant une compétence "en cours d'acquisition", donc fragile, pour de nombreux élèves en fin d'école primaire. Il est donc important de réfléchir à des dispositifs et des outils susceptibles de favoriser le développement de ces procédures morphosyntaxiques et leur intégration dans une démarche réflexive d'analyse et de contrôle.

Hirsch livra en 1884 quatre verrières évoquant l’histoire de l’institution, mises en place dans les deux escaliers, et en 1888 un grand vitrail allégorique destiné au fond du vestibule central de l’établissement, depuis déposé. Un complément du décor vitré de cette grande salle avait été prévu pour les fenêtres latérales mais fut finalement abandonné, après que le peintre Albert Besnard, auteur des peintures murales, eût dessiné en 1889 huit vitraux à sujets animaliers. On doit cependant à des initiatives privées la réalisation par Henri Carot de deux verrières tirées des cartons de Besnard.Built from 1877 to 1882 by Charles-Jean Laisné, the main façade of the École de Pharmacie opens onto the Avenue de l’Observatoire (Paris, 6th arr.. The new school was richly decorated with sculpture, wall-painting and stained-glass. According to the architect’s wishes, Émile Hirsch, his collaborator on previous restoration operations, was commissioned for the stained-glass windows. In 1884, the parisian glazier delivered four windows with historical subjects related to the institution, which took place in the two stairways, and in 1888 an allegorical stained-glass for the main hall, now removed. Laisné intended to complete the decoration of this hall with eight new windows, representating animals in their natural surroundings. Designed in 1889 by Albert Besnard, the painter who decorated the walls of this room, they were in fact not executed. But two of them were realized later by Henri Carot for private commissioners.

The implementation of the overall modelling process includes a one-dimensional hydraulic model to qualitatively characterize the sediment transport process under severe flooding conditions downstream of the potential mining site, a two-dimensional ANSYS Fluent model to simulate the release of tailings from a containment cell located partially above the local ground surface into the nearby streams, and a one-dimensional finite-volume sediment transport model to examine the propagation of a tailings sediment pulse in the river network located downstream. The findings of this investigation aim to assist in estimating the potential impacts that tailings would have if they were transported into rivers and reservoirs located downstream of the Coles Hill deposit that serve as municipal drinking water supplies.

    2010-01-01

    Cole Porter (1891-1964), an American musical icon, has been internationally acknowledged as one of the most cosmopolitan, sophisticated, elegant and influential composer-lyricists of the 20th century. Born in Indiana and raised in wealth and privilege, he attended both Yale and Harvard universities where he honed his song-writing skills. In his 800 tunes, many of which became smash hits, he blended fresh, witty, urbane and colloquial lyrics with catchy, singable melodies. He composed musical scores for both Broadway stage and Hollywood movies, but focused on the former. While Porter enjoyed penning comic songs, he rarely had them published. In 1946, Cole wrote the music and lyrics for a Broadway show entitled Around the World in Eighty Days. Deemed a failure, it closed after only 75 performances. One light-hearted ditty, "Snagtooth Gertie", which he composed for the show, was never used. The lyrics are presented for the first time in this paper.

    XerCD-mediated recombination at cer converts multimers of plasmid ColE1 to monomers, maximizing the number of independently segregating molecules and minimizing the frequency of plasmid loss. In addition to XerCD, recombination requires the accessory factors ArgR and PepA. The promoter P(cer), located centrally within cer, is also required for stable plasmid maintenance. P(cer) is active in plasmid multimers and directs transcription of a short RNA, Rcd, which appears to inhibit cell division. It has been proposed that Rcd is part of a checkpoint which ensures that multimer resolution is complete before the cell divides. This study has shown that ArgR does not act as a transcriptional repressor of P(cer) in plasmid monomers. P(cer) is unusual in that the -35 and -10 hexamers are separated by only 15 bp and this study has demonstrated that increasing this to a more conventional spacing results in elevated activity. An increase to 17 bp resulted in a 10- to 20-fold increase in activity, while smaller effects were seen when the spacer was increased to 16 bp or 18 bp. These observations are consistent with the hypothesis that P(cer) activation involves realignment of the -35 and -10 sequences within a recombinational synaptic complex. This predicts that a 17 bp spacer promoter derivative should be down-regulated by plasmid multimerization, and this is confirmed experimentally.

  1. Automated criterion-based analysis for Cole parameters assessment from cerebral neonatal electrical bioimpedance spectroscopy measurements

    2012-01-01

    Hypothermia has been proven as an effective rescue therapy for infants with moderate or severe neonatal hypoxic ischemic encephalopathy. Hypoxia-ischemia alters the electrical impedance characteristics of the brain in neonates; therefore, spectroscopic analysis of the cerebral bioimpedance of the neonate may be useful for the detection of candidate neonates eligible for hypothermia treatment. Currently, in addition to the lack of reference bioimpedance data obtained from healthy neonates, there is no standardized approach established for bioimpedance spectroscopy data analysis. In this work, cerebral bioimpedance measurements (12 h postpartum) in a cross-section of 84 term and near-term healthy neonates were performed at the bedside in the post-natal ward. To characterize the impedance spectra, Cole parameters (R 0 , R ∞ , f C and α) were extracted from the obtained measurements using an analysis process based on a best measurement and highest likelihood selection process. The results obtained in this study complement previously reported work and provide a standardized criterion-based method for data analysis. The availability of electrical bioimpedance spectroscopy reference data and the automatic criterion-based analysis method might support the development of a non-invasive method for prompt selection of neonates eligible for cerebral hypothermic rescue therapy.

    The three key lepidopteran pests of cole, Brassica oleracea L., crops in North America are diamondback moth, Plutella xylostella (L.) (Lepidoptera: Plutellidae); cabbage looper; Trichoplusia ni (Hübner) (Lepidoptera: Noctuidae); and imported cabbageworm, Pieris rapae (L.) (Lepidoptera: Pieridae). Two species-specific pheromone-based experimental attracticide formulations were evaluated against these pests: LastCall DBM for P. xylostella and LastCall CL for T. ni. No LastCall formulation was available against P. rapae. Laboratory toxicity experiments confirmed the effectiveness of each LastCall formulations in killing conspecific males that made contact. In replicated small plots of cabbage and collards in central Alabama, over four growing seasons (fall 2003, spring 2004, fall 2004, and spring 2005), an attracticide treatment receiving the two LastCall formulations, each applied multiple times at the rate of 1,600 droplets per acre, was compared against Bacillus thuringiensis. subspecies kursatki (Bt) spray at action threshold and a negative untreated control. Efficacy was measured by comparing among the three treatments male capture in pheromone-baited traps, larval counts in plots, and crop damage rating at harvest. LastCall provided significant reductions in crop damage comparable to Bt in three of the four seasons. Efficacy of LastCall was dependent upon lepidopteran population densities, which fluctuated from season to season. In general, reduction in crop damage was achieved with LastCall at low-to-moderate population densities of the three species, such as typically occurs in the fall in central Alabama, but not in the spring when high P. rapae population pressure typically occurs in central Alabama. Significant reductions in pheromone trap captures did not occur in LastCall plots, suggesting that elimination of males by the toxicant (permethrin), rather than interruption of sexual communication, was the main mechanism of effect.

    Full Text Available ColE1 plasmids are important vehicles for the spread of antibiotic resistance in the Enterobacteriaceae and Pasteurellaceae families of bacteria. Their monitoring is essential, as they harbor important resistant determinants in humans, animals and the environment. In this work, we have analyzed ColE1 replicons using bioinformatic and experimental approaches. First, we carried out a computational study examining the structure of different ColE1 plasmids deposited in databases. Bioinformatic analysis of these ColE1 replicons revealed a mosaic genetic structure consisting of a host-adapted conserved region responsible for the housekeeping functions of the plasmid, and a variable region encoding a wide variety of genes, including multiple antibiotic resistance determinants. From this exhaustive computational analysis we developed a new PCR-based technique, targeting a specific sequence in the conserved region, for the screening, capture and sequencing of these small plasmids, either specific for Enterobacteriaceae or specific for Pasteurellaceae. To validate this PCR-based system, we tested various collections of isolates from both bacterial families, finding that ColE1 replicons were not only highly prevalent in antibiotic-resistant isolates, but also present in susceptible bacteria. In Pasteurellaceae, ColE1 plasmids carried almost exclusively antibiotic resistance genes. In Enterobacteriaceae, these plasmids encoded a large range of traits, including not only antibiotic resistance determinants, but also a wide variety of genes, showing the huge genetic plasticity of these small replicons. Finally, we also used a metagenomic approach in order to validate this technique, performing this PCR system using total DNA extractions from fecal samples from poultry, turkeys, pigs and humans. Using Illumina sequencing of the PCR products we identified a great diversity of genes encoded by ColE1 replicons, including different antibiotic resistance

    Full Text Available Los coleópteros coprófagos tienen una valiosa función en el equilibrio ecológico de los agroecosistemas debido a su importancia en la limpieza de praderas y en la fertilidad del suelo. El objetivo de este estudio fue determinar el comportamiento reproductivo de coleópteros coprófagos en condiciones de laboratorio. Los escarabajos se recolectaron directamente de bostas en cinco fincas ganaderas del piedemonte de Casanare, Colombia. En el laboratorio se hizo la determinación taxonómica y el mantenimiento de varios ejemplares para observar su comportamiento, ciclo de vida y tasa de reproducción. Las especies encontradas fueron: Ateuchus aeneomicans, Aphodius granarius, Aphodius sp., Dichotomius agenor, Dichotomiussp. y Digitonthophagus gazella. Se logró mantener en el laboratorio únicamente la especie A. aeneomicans, de la cual se determinó su ciclo de vida. El tiempo desde huevo hasta adulto osciló entre 60 y 68 días; su tasa de reproducción se estimó en 0,21 individuos por semana. Durante seis meses de observación la población de A. aeneomicans se mantuvo constante; probablemente las condiciones de laboratorio no fueron las óptimas para su incremento poblacional.

    Full Text Available O filme Uma vida iluminada (2005, com roteiro e direção de Liev Schreiber, baseado no romance Tudo se ilumina, de Jonathan Safran Foer, narra a história de um jovem judeu norte-americano que viaja para a Ucrânia em busca de seu passado. A coleção para o protagonista do filme e para a mulher que ele encontra em Trachimbrod, sobrevivente de um massacre que destruiu toda a sua família, é de fundamental importância. Ambos os personagens reúnem objetos como forma de lutar contra a dispersão e o esquecimento, assim como argumentou Walter Benjamin sobre o colecionador. Em Uma vida iluminada, essa luta está intrinsecamente ligada à memória judaica, constantemente ameaçada por regimes totalitários.

    Virginia Uranium, Inc. (“VUI”) is an exploration and development company that holds exclusive rights to the world class Coles Hill uranium project in Pittsylvania County, Virginia. This project has the potential to supply significant uranium to the market. Since the 1980s over US$60 million has been expended to advance the project. The Coles Hill uranium deposit is located in south central Virginia and is probably the largest undeveloped uranium deposit in the United States. It has a measured and indicated resource of 119 million pounds of U{sub 3}O{sub 8}{sup (A)} {sup (B)} at a cut-off grade of 0.025% U{sub 3}O{sub 8} based on a National Instrument 43-101 technical report prepared for Santoy Resources Ltd. and Virginia Uranium, Inc. by Behre Dolbear and Company, Ltd., Marshall Miller and Associates, Inc., and PAC Geological Consulting Inc. dated February 2, 2009 and revised April, 2009. The whole rock analyses of the deposit indicate a relatively monomineralic ore that does not contain quantities of heavy metals that are typical of uranium ores of the southwestern United States. The Colorado School of Mines Research Institute conducted mill mineral processing tests in the 1980s. Project pre-feasibility studies and other plans completed in the 1980s will be updated over the next 12 months.Mining and support personnel can reasonably be recruited from the local area, as the skill sets needed for miners exist already among people and companies who are comfortable with farming and heavy equipment. Virginia currently requires that uranium mining regulations and permitting be adopted by law prior to approving a mining operation at Coles Hill. Virginia has regulated and permitted many similar mining industries. In fact, lead has been mined in the state from 1750–1981 and heavy metal sands have been mined since 1991 in Dinwiddie County that is over 90 miles/144 kilometers east of Coles Hill.

    Science.gov (United States)

    Schmidt, Anja; Thordarson, Thorvaldur; Oman, Luke D.; Robock, Alan; Self, Stephen

    2014-01-01

    Here we respond to the comments by Cole-Dai et al. [2014] on our article Schmidt et al. [2012]. Specifically, in response to section 2 of their reply, we argued in Schmidt et al. [2012] that based on previously published estimates of the volatile release height during the 1783-1784 C.E. Laki eruption, the lack of a sulfur massindependent fractionation (MIF) anomaly is expected. In other words, no previous study on Laki ever argued that this eruption emitted SO2 into altitudes >13-15 km. In section 2.3, Cole-Dai et al. [2014] argue that the nonzero ?33S value of their Laki sample 1 may be explained by a short-lived explosive phase at Laki during which volatiles reached the stratosphere. In Schmidt et al. [2012] in section 2, we argued in agreement with Cole-Dai et al. [2014] (section 3.1) that for a MIF anomaly to be preserved, the Laki volatiles would have had to be emitted in >20 km altitude. Our main point is that eruption column heights >20 km are unlikely based on the historical accounts and plume-rise modeling for the Laki eruption [Stothers et al., 1986; Woods, 1993; Thordarson and Self, 2003]. In Schmidt et al. [2012], we argued that to deduce a short-lived climatic impact of the Laki eruption based on the lack of a MIF anomaly and the length of the sulfate deposition in Greenland ice cores may be misleading because the climatic impact will outlast the radiative forcing of the Laki aerosol cloud. Cole-Dai et al. [2014] acknowledge the latter in their reply in section 4.2. We agreewith Cole-Dai et al. [2014] in that themagnitude and length of the climatic impact during the winter of 1783-1784 depends on the altitude of the volatile release during the eruption (sections 2.3 and 4.2). However, even if we assumed that during Laki all sulfur dioxide (SO2) would have been released in the troposphere, then the aerosol cloud would still be present in the upper troposphere during March 1784, as is evident from independent model simulations of this "tropospheric

  15. Une école de la maturation ? A gestation school ? Analysis of artistic teaching between immediate gift, academic rhythm and creation process

    Jérémie Vandenbunder

    2011-11-01

    Full Text Available Cet article porte sur l'enseignement artistique tel qu'il est délivré dans les écoles des Beaux-arts françaises. Il montre comment les acteurs investis dans ces formations, que ce soit les étudiants ou les enseignants, sont pris dans des jeux aux temporalités différentes. Posant tout d'abord comme paradoxale l'opposition entre l'innéité du don, valorisé aux beaux-arts, et la nécessité de suivre des études longues, nous tentons de montrer que le mythe de l'autodidaxie s'inscrit dans une perspective de socialisation propre au domaine des arts plastiques. Centré sur la socialisation professionnelle, dans le sillage des sociologues de l'École de Chicago, l’article présente les différentes étapes de ce processus en identifiant les stratégies et perspectives adoptées par les étudiants. Par ce biais, il met en lumière le passage progressif des élèves du monde profane au groupe professionnel. Enfin, il détaille la manière dont les formes atypiques d'organisation du travail, comme le travail par projets, sont appréhendées dans les écoles, en lien avec les contraintes du milieu scolaire.In French art schools, temporality is obviously an issue for students and teachers alike. First, while teachers and students are insisting on gift and talent, they also put the stress on the need to study and experiment in the long run. I consider this “myth of autodidaxy” as a sign of professional socialization. Art students are trying to assimilate their own path with the myths of artistic life. In addition to that, I have followed the steps of this socialization for five years, the length of an entire art school curriculum. As students, young artists have to leave behind their initial stereotypes on artists and the art world in order to enter the professional world. Eventually, I try here to analyze how specific forms of work and organization such as project-based work are taught in art schools and how students deal with them.

    In april 1913, the director of the École supérieure de pharmacie, professor Bruntz, undertook the realization of a historical museum and of a gallery of photographies of professors. A society, the Société lorraine du musée historique de la pharmacie, was found in 1.914 and the collections increased rapidly. After First World War, no activity occured until 1926 and space and hands were missing. In 1937, collections, except books, were transfered to the Musée historique lorrain de Nancy and the most interesting objects and documents were exposed. Books were finally deposited and stored in the university library. Today, the renovation undertaken in the Musée lorrain and the approaching transfer of the faculty are the ocasion of a new discovery of these historical collections. Many years after the disparition of the museum, it appears that its collections have been fairly well preserved.

    Full Text Available Cet article se propose d’examiner certains aspects de la transmission de connaissances scolaires dans les écoles publiques brésiliennes. Depuis les années 1980, en effet, le système scolaire s’est largement ouvert aux couches les plus défavorisées des populations urbaines, ce qui a provoqué des changements dans les modes de fonctionnement. Face à ce nouveau public, les exigences en termes de discipline et de travail scolaires se sont considérablement affaiblies, de même que le suivi des programmes. Par ailleurs, les enseignants surmenés qui occupent souvent plusieurs emplois pour compenser leurs bas salaires, manifestent un découragement évident tandis que les élèves s’habituent à un monde institutionnel tolérant qui ne propose plus une vraie rupture avec leur univers social d’origine.This article studies certain aspects of how knowledge is transmitted in Brazilian state schools. Since the 1980s, the school system has opened its doors to the most underprivileged segments of the urban populations, bringing about considerable changes in day-to-day behavior patterns. Faced with this new public, requirements in terms of discipline and dedication to learning have considerably weakened, as has the observance of the official programs. Moreover, the teachers, exhausted since they often hold down several jobs to compensate for their low wages, are prone to depression. The pupils, in turn, get used to a tolerant institutional world which no longer represents a departure from their original social environment.

    Full Text Available Resumo Este artigo trata do processo de diálogo sobre coleções etnográficas de objetos Ka’apor e da curadoria compartilhada da exposição “A Festa do Cauim”, atividades promovidas pelo Museu Nacional de Etnologia de Leiden (NME, Holanda, junto ao Museu Paraense Emílio Goeldi (MPEG, Brasil, e o povo indígena Ka’apor da Terra Indígena Alto Turiaçu, localizada no estado de Maranhão, na Amazônia brasileira. É reflexo de uma mudança de filosofia no NME em direção a uma atividade mais inclusiva e colaborativa, como também dos processos de atuação com povos indígenas promovidos no Museu Goeldi e da necessidade política dos Ka’apor de chamar atenção, em nível nacional e internacional, para a defesa de seus direitos territoriais, continuamente ameaçados por atores envolvidos com a exploração ilegal de madeira no seu território. Considerando diferentes enfoques disciplinares, principalmente da antropologia e da museologia, em consonância com o pensamento indígena, assim como com as negociações de interesses e encontro de diversas perspectivas cognitivas e posicionamentos políticos, este artigo, além de documentar e refletir sobre a produção cocriativa de uma exposição etnográfica, procura repensar as dimensões cognitiva, política e ética deste tipo de trabalho com povos indígenas.

    Full Text Available A cagaiteira é uma espécie frutífera comum no bioma Cerrado. A planta produz um fruto do tipo baga que é consumido in natura ou processado de várias formas. Em função do potencial produtivo da espécie, existe interesse na sua domesticação, para produção em larga escala. Para atender esse objetivo, a avaliação da variabilidade genética é fundamental para subsidiar programas de melhoramento e domesticação da espécie. Nesse sentido, o objetivo do trabalho foi estimar parâmetros genéticos quantitativos da coleção de germoplasma de Eugenia dysenterica DC., para disponibilizar informações que possam ser úteis em programas de melhoramento da espécie. O experimento foi montado no ano de 1998 em delineamento experimental de blocos completos ao acaso com 110 tratamentos e quatro repetições. Foram avaliadas as variáveis das plantas que incluem a altura (AP, altura da primeira bifurcação (AB, circunferência do caule a 10 cm do solo (CC, projeção média da copa (DC e variáveis das folhas, que incluem o comprimento do limbo (CL, largura do limbo (LL, formato das folhas (FF e comprimento do pecíolo (CP. Os coeficientes de herdabilidade ao nível das médias variaram entre 87,66% e 25,16% e os coeficientes de variação genética, entre 45% e 7%, valores próximos aos obtidos para outras espécies silvestres do Cerrado. As estimativas dos parâmetros sugerem respostas modestas à seleção para as variáveis das plantas e respostas expressivas para as variáveis das folhas.

Si la valorisation scientifique des travaux réalisés sous ce régime est visible dans les supports habituels, il n’en va pas de même de l’activité partenariale elle-même et des processus qui participent à sa constitution. L’analyse des narrations des protagonistes des partenariats permet de mettre en visibilité les phénomènes qui font la spécificité de cette activité, que les modèles de la diffusion sont impuissants à saisir. Prise entre pratique ordinaire, activité professionnelle et activité scientifique, soumise à la temporalité du processus, l’activité partenariale interroge la conception même du savoir qui sous-tend les modèles de recherche appliquée.Research partnership in the Swiss Universities of applied sciencesAt the heart of the new research policies tending towards innovation, the Swiss Universities of applied sciences, recently promoted to tertiary academic rank, have been given, as primary mission, to extend their activities in Applied Research and Development. If scientific valorization of this kind of research is visible in current media and publications, it is not so apparent for the partnership itself or the processes which constituted its development in the first place. The analysis of the narrations of the protagonists of the partnership shows the phenomenon which illustrates the specificity of this activity, that valorization models are unable to grasp. Caught between regular practice, professional and scientific activities, subject also to the temporality of the process, partnership activities question the very concept of the knowledge which underlines the models of applied research.Investigaciones conjuntas en Escuelas Superiores de Sanidad y Trabajo Social en Suiza

    Full Text Available Cet article présente une recherche-action, menée à l'École Nationale des Ponts et Chaussées (ENPC, qui avait pour but de s'interroger sur les potentialités d'Internet en classe de Français Langue Étrangère (FLE lors de l'"enseignement" de la culture et / ou civilisation à un public spécialiste d'autres disciplines. Pour vérifier et contrôler notre hypothèse de départ, relevant des domaines, d'une part, des Technologies de l'Information et de la Communication (TIC, et d'autre part, de la didactique des langues, deux cours thématiques ont été mis en place, "La France et ses controverses" et "Partager la culture des Français". Ils proposent, lors de séances en présentiel, d'utiliser Internet comme support pédagogique. Le contenu de ces séances est axé sur une approche culturelle. D'abord, cette étude traite, tout en s'appuyant sur les fondements de la didactique des langues, de différents repères TIC et des approches culturelles liées aux TIC. Ensuite, nous présentons l'expérimentation réalisée au cours de l'année académique 2004-2005 et les résultats obtenus. Enfin, nous discutons des avantages d'une telle approche de l'"enseignement / apprentissage" de la culture et / ou civilisation, de la valeur ajoutée d'Internet et des pistes pédagogiques pour une recherche future.This article presents a research project carried out at École Nationale des Ponts et Chaussées (ENPC, one of France's leading engineering schools.

    Full Text Available The purpose of the Technology and High School Success (THSS initiative was to encourage innovative strategies focused on improving provincial high school completion rates, using technology and student-centered learning to engage student interest. The primary purpose of this paper is to report on barriers that impede systemic, effective and sustainable technology integration within schools. Even with teacher and administrative support and commitment for THSS, evaluative research indicated minimal change in system capacity as a result of the initiative. Three primary barriers to program sustainability were: 1 schools and school districts did not leverage the opportunity to revisit their existing vision(s, 2 schools and school districts did not use data to make changes, and 3 limited access to technology. Le but de l’initiative « Technology and High School Success (THSS » était d'encourager des stratégies novatrices visant à améliorer le taux d’achèvement des études secondaires dans la province de l’Alberta en utilisant la technologie et un apprentissage centré sur l'élève afin de susciter l'intérêt des élèves. L'objectif principal de cet article est de rendre compte des obstacles entravant l'intégration systémique, efficace et durable de la technologie dans les écoles. La recherche évaluative a révélé des changements minimes dans la capacité systémique à la suite de l'initiative, et ce, malgré l’appui et l’engagement des enseignants et des administrateurs envers le THSS. Les trois obstacles principaux à la viabilité du programme sont les suivants: 1 les écoles et les districts scolaires n'ont pas profité de l’occasion pour revoir leur(s vision(s, 2 les écoles et les districts scolaires n'ont pas utilisé les données pour effectuer des changements, et 3 l'accès limité à la technologie.

    Dans cette étude nous cherchons d'évaluer de manière détaillée l’importance relative de la phonologie et des connaissances lexicales de 43 enfants français à l’entrée du CP et d'analyser les problématiques causées par les phénomènes consonantiques de liaison, d’élision et d’enchaînement dans cette phase d'acquisition. Les résultats d'une tâche de dénomination guidée montrent que les enfants de 6 ans et demi ont encore des problèmes avec le calcul des frontières des mots en français au début de l'école primaire. De plus dans nos données, la fréquence lexicale des mots tests ne résulte pas corrélée au nombre d'erreurs. Les fautes résiduelles dans la tâche sont donc consécutives à un problème phonologique et pas exclusivement lexical. Le rôle prioritaire de la phonologie à l'entrée de l'école primaire est en accord avec les conclusions de Sprenger-Charolles (1994 qui proposent que la première phase d’apprentissage de la lecture et de l'écriture repose essentiellement sur une analyse phonologique indépendante de la fréquence lexicale.

    Full Text Available The objectives of this work were to optimize the isozyme electrophoresis technique for Bixa orellana, and use isozyme markers for a preliminary survey on the genetic variability in Brazilian annatto germplasm accessions. Collection consisted of seed samples from sixty open pollinated trees, representing two Northern and four Southern geographic provenances. The extraction, electrophoresis, and interpretation of annatto isozymes are described. Three out of the twenty-one identified isozyme loci were polymorphic in the collection. The percentage of polymorphic loci (P = 21.05 and the expected heterozygosity in annatto (H T = 0.064 were low, compared to other tropical woody species. A UPGMA phenogram, constructed with Nei's genetic distances, clearly separated the germplasm provenant from North and Central Brazil. Variability was significantly higher among the accessions from Maranhão. A sharp genetic differentiation was detected between accessions from Maranhão and Pará States, despite their geographical proximity. The distinctive isozyme polymorphism, observed in the accessions from Maranhão, together with reports on local morphological heterogeneity in annatto fruit shape, color, and pubescence, calls for more detailed genetic and taxonomic investigation.Os objetivos deste trabalho foram: otimizar a técnica de eletroforese de isoenzimas para Bixa orellana, e usar marcadores isoenzimáticos para um estudo preliminar da variabilidade genética, presente em uma coleção de germoplasma de urucum.

A estratégia de amostragem utilizada foi baseada em análise multivariada, sendo adotada intensidade de amostragem de 20%. A estratificação dos acesos introduzidos foi realizada principalmente de acordo com o país de origem, local de avaliação e tipo de grão. Para os acessos melhorados considerou-se principalmente o tipo de grão e a instituição responsável pela realização do melhoramento do acesso. Verificou-se a necessidade de se realizar a caracterização e avaliação de muitos acessos introduzidos e melhorados. Foi possível observar a existência de variabilidade genética entre os acessos introduzidos e melhorados. As características altura de planta e peso de mil grãos foram as que mais contribuíram para a discriminação dos genótipos. A utilização combinada do método de Tocher tendo como medida de dissimilaridade a distância euclidiana invertida e a análise de dispersão gráfica com base nos três primeiros componentes principais foi eficiente.

    Full Text Available Partículas esferoidais de 50-60mμ de diâmetro foram encontradas em preparações semipurificadas e em preparações rápidas de plantas de couve infetadas com um vírus que induz faixa amarela das nervuras (VFANC. Essas partículas têm um capsídeo aparentemente icosaedral, constituído de 92 capsômeros de 50-60 A de diâmetro. Quando tratadas com acetato de uranila, revelaram a existência de uma zona central, que se impregna fortemente com êste corante, possìvelmente constituída de nucleoproteína. Tais partículas não foram encontradas em plantas sadias, mas foram nelas detectadas, após serem inoculadas por união de tecidos, por meios mecânicos ou por afídeos com VFANC. Partículas similares foram encontradas em secções ultra-finas de tecido foliar de couve infetado com o VFANC, porém apresentavam um diâmetro ligeiramente menor, da ordem de 35-45mμ. Invariàvelmente, essas partículas foram encontradas em meio às inclusões citoplasmáticas de forma e dimensões variadas, constituídas de uma massa amorfa, granular e densa. Tais inclusões puderam também ser observadas em secções mais espêssas e montadas para microscopia óptica. Possìvelmente o VFANC pertence ao grupo do vírus do mosaico da couve-flôr, dada a semelhança na morfologia das partículas e nas moléstias induzidas.Spherical particles, 50-60 mμ, in diameter were found in partially purified preparalions, and also in quick preparations made from plants infected with a virus inducing yellow vein banding in cole (Brassica oleracea var. acephala . These particles apparently had an icosahedral capsid composed by 92 capsomeres, each with 50-60 A in diameter. Uranyl acetate treatment of these particles revealed a central zone, about 25-30 mμ in diameter, which bound strongly with the stain, indicating that this part of the particle is nucleoprotein. Such particles were absent in healthy plants, but they were detected after these plants were inoculated by

    Nilton Ken Ota

    Full Text Available RESUMO: Em grande medida, os estudos sobre a constituição do arcabouço teórico do lacanismo têm ocorrido ao largo do exame de sua historicidade. Essa negligência reforça o ocultamento do processo social que levou a produção lacaniana a uma profunda integração entre a formalização e a etificação da teoria. Esse processo não pode ser compreendido sem a contextualização crítica da conjuntura política que cercou a proposta e a existência da École Freudienne de Paris (EFP, fundada por Lacan, em 1964. A estreita convivência com os jovens militantes dos grupos da esquerda extraparlamentar da época, notadamente os maoístas, e a assimilação de suas problematizações fizeram do pensamento lacaniano e da EFP o espaço de objetivação de um discurso movido pela paráfrase política e seus efeitos de engajamento. Este artigo pretende expor as linhas de estruturação político-social dos conceitos forjados por Lacan, em meio à instituição e à consolidação de sua Escola.

    Pierre-Louis Laget

    2011-12-01

    Full Text Available L’enseignement de la médecine fait directement au lit du malade ou leçons cliniques fut une des grandes innovations pédagogiques du XVIIIe siècle touchant la discipline médicale. L’initiative d’instaurer un tel enseignement est généralement attribuée au médecin hollandais Herman Boerhaave qui en conçut l’institution dès sa nomination en 1714 comme professeur à l’Université de Leyde. A Paris ce fut seulement à partir de 1780 que le médecin Louis Desbois de Rochefort commença à donner des leçons cliniques à l’hôpital de la Charité. La supériorité acquise par cet hôpital du fait de la nouveauté de l’enseignement qui y était dispensé explique pourquoi, lors de la création des écoles de santé par la Convention nationale le 14 frimaire an III (4 décembre 1794, ce fut ce lieu qui fut choisi pour y établir la première école de médecine clinique qui serait dotée de locaux tout spécialement adaptés à sa fonction. En raison des aléas budgétaires liés à la conjoncture politique, le chantier se trouva plusieurs fois interrompu, mais finalement conduit à terme. Des aménagements importants effectués à l’occasion de ces travaux, dans ce qui était la chapelle de l’hôpital de la Charité, par l’architecte Nicolas-Marie Clavareau, en est résulté une œuvre architecturale à part entière. Par une ironie de l’histoire, la partie principale de la chapelle a retrouvé récemment une vocation cultuelle, sans que cela conduise pour autant à la disparition des aménagements conçus pour l’installation de l’école de médecine clinique. Ceux-ci constituent ainsi un exceptionnel témoignage de l’architecture de l’époque révolutionnaire qui a infiniment plus brillé par ses projets que par ses réalisations.Medical education directly delivered at the bedside, i.e. clinical lessons, was one of the great eighteenth-century educational innovations affecting medical learning.

    Full Text Available « La nation qui ne sait d’où elle vient ne sait pas non plus où elle va ». Ces mots nous rappellent le rôle de l’histoire et son enseignement dans les différentes nations. En effet, l’histoire et son apprentissage permettent aux citoyens de connaître non seulement leur passé, mais aussi de transmettre la mémoire collective, de former l’esprit national et de développer une conscience politique commune. Cependant, dans les nations multiculturelles que connaissent le monde actuel, l’élaboration d’une même histoire nationale semble irréalisable voir même impensable, du fait que chaque groupe ethnique dispose d’un passé, d’une culture et de valeurs particuliers qu’il ne partage pas avec les autres groupes. Dans plusieurs pays multiethniques, l’accomplissement d’une histoire commune, la fabrication des manuels scolaires et l’enseignement de l’histoire nationale peuvent même provoquer des émotions de mépris, de haine, etc., entre les citoyens qui partagent pourtant la même nation. Dans cette contribution, nous verrons en quoi l’enseignement de l’histoire peut susciter les émotions négatives à l’école. Emotions in the Teaching of History: To what Extent Can the Teaching of History Provoke Negative Emotions in Schools? Abstract: “The nation that does not know where it comes from does not know where it is headed either.” These words remind us of the role of History and its teaching in different nations. Indeed, History and its teaching allow citizen not only to know their past but also to pass on collective memory, forge a national spirit and develop a collective political consciousness. However, in today’s world’s multicultural nations, producing a common national History seems an unachievable goal, if not unconceivable, since each ethnic group has its own past, its own culture and values which are not shared with other groups. In many countries that are multi-ethnic, attaining a common

    Full Text Available La réussite scolaire à l’école primaire se caractérise généralement par un écart significatif en faveur des filles, sauf dans le domaine scientifique. De nombreux facteurs explicatifs sont proposés pour tenter d’expliquer ce phénomène, sur le versant pédagogique, psychologique ou encore sociétal. Nous privilégions ici une piste « endogène », associant les contenus d’enseignement et les types de réponses construites par les élèves en résolution de problèmes en classe de CM1. La convergence des résultats statistiques et des analyses de productions d’élèves, sur un échantillon de près de 2 000 élèves, à partir de la passation de deux tests en cours d’année scolaire, conduit à observer, en filigrane, de meilleurs résultats et procédures de résolution chez les filles. Ce résultat, a priori inattendu, semble corroborer l’hypothèse que les filles seraient, quelque soit le domaine d’apprentissage, plus efficaces dans l’appréhension d’un exercice difficile. De plus, leurs progressions d’un test à l’autre montrent qu’elles ne sont pas discriminées par les pratiques pédagogiques mises en œuvre en mathématiques.Academic achievement in primary schools usually confirm the supremacy of girls, except in scientific areas. Most results highlight the influence of the social context, the teaching methods or the psychological parameters. From the “internal” point of view, especially the analysis of the influence of academic factors, the items in mathematics and the nature of pupils answers potentially contribute to the explanation of gender performance in primary schools. According to the results of two standardized examinations on a sample of 2000 pupils, the qualitative approach reveal best scores and procedures among girls. This could lead to the conclusion that the fact of facing of difficulties in mathematics allow girls to make better progressions than boys. In addition, these

    Full Text Available Apesar de a disciplina Química integrar o currículo da Educação Básica apenas no nível médio de ensino, nos primeiros anos da escolarização é possível fazer referência a essa ciência. Além disso, a produção focando as Ciências Naturais para as séries iniciais tem crescido, mas ainda poucas pesquisas podem ser encontradas. O objetivo deste artigo foi levantar o tratamento dos conceitos básicos para o estudo da Química em livros didáticos de Ciências de 1ª à 4ª série do Ensino Fundamental, aprovados pelo PNLD/2007. As coleções foram analisadas quanto à sequência conceitual de acordo com a Teoria da Aprendizagem Significativa. Foram encontradas inadequações na definição dos conceitos e na sequência conceitual, quando alguns conceitos foram abordados posteriormente aos seus subsunçores. Ao mesmo tempo, vários exemplos adequados de definição e tratamento desses conteúdos foram levantados. Espera-se, assim, contribuir para a discussão sobre o ensino dos conteúdos básicos para o estudo da Química nas séries iniciais. Especialmente, quando se estabelece o primeiro contato do estudante com um conceito científico ou com um campo do conhecimento, é importante que a evolução dos conceitos seja feita de maneira cuidadosa. A baixa preocupação dada ao tratamento sequencial de conceitos pode levar à formação de – ou reforçar – concepções alternativas que dificultam o aprendizado de conteúdos posteriores, quando esses estudantes ingressarem no Ensino Médio. Although the Chemistry discipline integrates the education curriculum only at high school level, it is possible to refer to this science in the early years of schooling. Furthermore, despite the fact that research production focusing on natural sciences for the initial grades has grown, still only few studies on the subject can be found. The purpose of this article was to survey basic concepts for the study of chemistry treated in science

    , instead, it could favor the biota, at least at short time scalesLa pérdida y fragmentación del hábitat han sido consideradas como las principales causas de la disminución de biodiversidad. La pérdida de hábitat es una disminución del hábitat utilizable por los organismos y la fragmentación es un cambio en la configuración espacial del paisaje, donde los fragmentos remanentes quedan relativamente aislados entre sí. Trabajos teóricos recientes indican que los efectos de la pérdida de hábitat son más importantes que los de la fragmentación, sin embargo existen pocos estudios experimentales que evalúen por separado ambos procesos. Para estudiar los efectos de la fragmentación per se sobre la abundancia y riqueza de especies de coleópteros epigeos, se crearon 15 micro-paisajes de alfalfa de 30 x 30 m distribuidos en tres bloques. Doce de ellos se fragmentaron removiendo el 84 % del hábitat, dejando cuatro ó 16 fragmentos separados por 2 ó 6 m. Entre diciembre del 2002 y abril del 2003, antes y después de la fragmentación, se muestrearon los coleópteros mediante trampas Barber. Se capturó un total de 8.074 coleópteros de 75 especies pertenecientes a 16 familias. El tipo de paisaje no afectó la abundancia de coleópteros, sólo Anthicidae fue más abundante en los paisajes de 4 fragmentos separados por 2 m y fue más abundante en la matriz. El resto de de las familias fue más abundante en los fragmentos, significativamente Carabidae y Lathridiidae. La riqueza de especies por trampa y por paisaje fue mayor en los paisajes con 16 fragmentos separados por 6 m, concentrándose en los fragmentos. Contrario a lo descrito en la mayor parte de la literatura, la fragmentación no afectó negativamente la abundancia y riqueza de especies de coleópteros epigeos asociados a alfalfa. Más bien, fragmentos de alfalfa más pequeños y aislados ofrecieron un refugio de hábitat para la biodiversidad de coleópteros epigeos. Estos resultados concuerdan con los

    Full Text Available Coccidioidomycosis is an emerging fungal disease in Brazil; adequate maintenance and authentication of Coccidioides isolates are essential for research into genetic diversity of the environmental organisms, as well as for understanding the human disease. Seventeen Coccidioides isolates maintained under mineral oil since 1975 in the Instituto de Medicina Tropical de São Paulo (IMTSP culture collection, Brazil, were evaluated with respect to their viability, morphological characteristics and genetic features in order to authenticate these fungal cultures. Only five isolates were viable after almost 30 years, showing typical morphological characteristics, and sequencing analysis using Coi-F and Coi-R primers revealed 99% identity with Coccidioides genera. These five isolates were then preserved in liquid nitrogen and sterile water, and remained viable after two years of storage under these conditions, maintaining the same features.Coccidioidomicose é uma doença emergente no Brasil; a manutenção adequada e autenticação de isolados de Coccidioides spp são essenciais para a pesquisa em diversidade genética de micro-organismos, bem como para a compreensão da doença em humanos.

Dos 17 isolados, apenas cinco foram viáveis após quase 30 anos mantidos em óleo mineral, apresentando características morfológicas e moleculares típicas do gênero, o sequenciamento utilizando os oligonucleotídeos Coi-F e Coi-R revelou identidade de 99% com isolados de Coccidioides.

A análise aqui apresentada centra-se na abordagem dos gêneros textuais orais e escritos presente nestas obras, uma vez que essa abordagem encontra-se no cerne da proposta de incorporar uma visão de ensino de LE centrada na língua em uso, como prática social. Os resultados demonstraram uma tendência positiva de mudança, resultante da inserção das línguas estrangeiras no PNLD. Essa tendência poderá compor um novo domínio discursivo para o livro didático de língua estrangeira brasileiro, incluindo a reafirmação dos conceitos de gênero textual, tipo textual, oralidade e escrita, por muito tempo, bastante negligenciados.This article aims at analyzing the two English textbooks approved by the National Textbook Program (PNLD/LE/2011 in Brazil. They have been compared to two other textbooks, published in the period prior to the implementation of the Program, and very widely used in Brazilian schools. The present analysis focuses on the spoken and written text genres of the textbooks in focus, since this pedagogical approach lies at the heart of the proposal to incorporate language in use as social practice in the teaching of English. The results showed a trend of positive change, after foreign languages textbooks were incorporated in the National Textbook Program. This trend can help reshape the discourse domain of English textbooks in Brazil, which includes the concepts of text genre and text type, in spoken and written language, which had been neglected for some time.

    Full Text Available Les écrits d’élèves constituent un corpus complexe à décrire pour le chercheur. Les productions ne sont pas homogènes d’un élève à un autre et l’enseignant est souvent démuni devant une telle diversité. Notre objectif est d’interroger la syntaxe écrite d’élèves de fin d’école primaire, en particulier sur le plan de la segmentation. Nous rappelons tout d’abord que, dans la grammaire scolaire, il est principalement fait référence à une phrase « graphique », pourtant critiquée, voire rejetée, par de nombreux linguistes. Nous proposons par la suite de recourir à une phrase que nous dénommons « syntaxique » (définie dans Feuillard (1989 et nous nous efforçons de montrer que la phrase « syntaxique » est une unité opératoire possible pour rendre compte des compétences effectives des élèves. En effet, en mesure de segmenter des productions écrites non normées, elle permet notamment de dissocier la segmentation elle-même et les effets de la segmentation que sont les signes de ponctuation et/ou les connecteurs. Les textes d’élèves observés sont décrits et analysés grâce, d’une part, au découpage en phrases « syntaxiques » et, d’autre part, à la mise en regard des phrases « syntaxiques » et des phrases « graphiques ». La segmentation est ensuite ramenée à la question du passage à l’écrit, examinée d’un côté à travers l’oralité, dont les textes, produits par des élèves dotés d’un « savoir-faire [d’abord] oral » (Béguelin, 2000, comportent des traces, mais aussi d’un autre côté à travers la brièveté. En effet, les productions d’écrits scolairement valorisées, autrement dit les productions vues comme marquant un passage à l’écrit réussi, semblent se caractériser par un moins grand écart entre le nombre de phrases « syntaxiques » et le nombre de phrases « graphiques ». Nous concluons notre propos en adoptant le point de vue

Ce texte, fondé sur une recherche doctorale de 2007 fait le point sur les caractéristiques du rôle de ces acteurs. Il met au jour un processus multifactoriel de transformation professionnelle et identitaire lié aux évolutions du champ de pratiques de l’informatique scolaire et reflété sur une liste de discussion. Cette liste, très réactive, constitue un lieu privilégié de socialisation professionnelle et répond à une fonction importante d’opérationnalisation des prescriptions. L’absence de cadrage institutionnel général et actualisé de ce rôle professionnel est la source d’une problématique identitaire et de légitimation de cette communauté de pratiques qui s’engage dans un processus de professionnalisation que la liste de discussion reflète. Au cours du temps, cette liste se constitue en une ressource au service d’une pratique experte, pratique que les ATICE cherchent à négocier avec l’institution en valeur d’échange.Since the mid-1980’s, a group of advisers has been appointed in primary schools in order to encourage teachers to use computers in their practice.

De ce fait, les travaux sur l’apprentissage du lexique en contexte scolaire ne portent généralement pas sur la période pré-élémentaire.

La communication présente les résultats de l’analyse d’un corpus transcrit d’une analyse d’une quinzaine de séances de langage en grande et en moyenne section. Elle montre que les procédures de reprise ou de reformulation qui sont à l’origine de l’apprentissage du lexique reposent essentiellement sur des mécanismes interactionnels, quel que soit le niveau des élèves. Plus les élèves sont faibles plus, ils ont besoin du matériel verbal déjà présent dans les échanges pour construire leurs propres interventions. Mais, c’est la même procédure que mobilisent les meilleurs élèves, à ceci près qu’ils sont capables aussi dans le même temps de l’appliquer à leur propre intervention. En s’appuyant sur des éléments verbaux déjà donnés et en reformulant des propositions qu’ils ont eux-mêmes construites, ils sont capables d’introduire dans des contextes adaptés des termes nouveaux dans leur intervention. Ce faisant, ils construisent les interventions les plus longues mais aussi qualitativement les plus intéressantes sur le plan lexical. Mais qu’on ne se méprenne pas, pour l’ensemble des élèves, c’est le développement de leurs compétences langagières, leur capacité à interagir avec les autres, qui est

At issue is a consideration of a section of Plutarch’s Against Colotes (1121E-1122F, which is a particularly important witness in favor of the actual existence of such a debate. The paper focuses not so much on the questions relevant such a debate – which are touched on here, but which themselves have an ample bibliography – but rather on the properly historiographical aspects, such as the identification of the beginner of the polemic or the reasons that brought it about. In reply to these inquiries it is possible to show that the originality of Colotes’ thought deserves much more serious consideration, also because Colotes played an important role within Epicureanism precisely as the originator of anti-Sceptic polemic.L’objet de cette étude est de chercher à reconstruire le débat entre l’école épicurienne et l’Académie sceptique au IIIe siècle avant J.-C.

En répondant à ces questions, on sera en mesure de montrer que l’originalité de la pensée de Colotès mérite d’être mieux mise en valeur, car Colotès a joué un rôle particulier au sein de l’épicurisme comme initiateur de la polémique anti-sceptique.Lo scopo del presente lavoro è cercare di ricostruire il dibattito intercorso tra la scuola epicurea e l’Accademia scettica nel

    Full Text Available Considering contemporary Anthropology’s debate around photography, there is a keen interest in the understanding of one of the most important open to public consultation photographic collections on 20th Century Brazil, that of Frenchman Marcel Gautherot (1910- 1996. The collection comprises around 25,000 photographs, purchased in 1999 by Instituto Moreira Salles and kept in its fund in the city of Rio de Janeiro. The text comments on the photographer’s work, linked to documentary projects under the patronage of institutions such as the Musée de l´Homme in Paris, at the end of the 1930s, and both the National Historic and Artistic Patrimony Service and the Brazilian Folklore Defence Campaign, in Brazil, between the years of 1940 -1960. Such commitments and interests define important thematic groupings in the production and organisation of his personal photographic archive. A discussion about criteria and technical procedures adopted by the photographer is attempted, detailing series and visual narratives about Brazilian culture’s density. With the photographs’ purchase by the IMS, the oeuvre’s aesthetic quality, now as an institutional collection, is highlighted. The collection’s manners of preservation and conservation, reproduction and circulation are redefined.

    Highlights: • We outline protocols for baseline geochemical surveys of stream sediments and water. • Regression on order statistics was used to handle non-detect data. • U concentrations in stream water near this unmined ore were below regulatory standards. • Concentrations of major and trace elements were correlated with stream discharge. • Methods can be applied to other extraction activities, including hydraulic fracturing. - Abstract: In this study, we determined baseline geochemical conditions in stream sediments and surface waters surrounding an undeveloped uranium deposit. Emphasis was placed on study design, including site selection to encompass geological variability and temporal sampling to encompass hydrological and climatic variability, in addition to statistical methods for baseline data analysis. The concentrations of most elements in stream sediments were above analytical detection limits, making them amenable to standard statistical analysis. In contrast, some trace elements in surface water had concentrations that were below the respective detection limits, making statistical analysis more challenging. We describe and compare statistical methods appropriate for concentrations that are below detection limits (non-detect data) and conclude that regression on order statistics provided the most rigorous analysis of our results, particularly for trace elements. Elevated concentrations of U and deposit-associated elements (e.g. Ba, Pb, and V) were observed in stream sediments and surface waters downstream of the deposit, but concentrations were below regulatory guidelines for the protection of aquatic ecosystems and for drinking water. Analysis of temporal trends indicated that concentrations of major and trace elements were most strongly related to stream discharge. These findings highlight the need for sampling protocols that will identify and evaluate the temporal and spatial variations in a thorough baseline study

It is characterized by the very small tympanum; the head is short and the snout rounded; the legs are long, the hands and feet unusually large, the latter extensively webbbed. The specific name is derived from the insular, irregular, or roughly triangular, dark spots, with a light halo, found mostly in the dorso-lateral region and on the legs. It belongs to the rain-forest fauna of the Marítime Range. The adult is a bromeliad-dweller and the tadpole rhyacophilous. DESCRIPTION. Vomerine teeth in two separate, oblique, groups, behind the large choanae, parallel to the posterior half of their inner border. Tongue entire, short, very broad and hardly free behind. Snout short, rounded, with distinct canthus rostralis and gradually sloping loreal region. Eye very large and prominent, its horizontal diameter almost equal to the distance between its anterior corner and the tip of the snout. Tympanum very small, less than one third of the diameter of the eye, but distinct, partly covered by a short, heavy ridge. Lateral fingers less than one third webbed; fourth finger slightly longer than the second, just reaching the base of the disk of the third; subarticular tubercles well developed; an angular pollex rudiment, more noticeable in the males. Toes almost completely webbed, the edge of the web inserted at the base of the disk on the third and the fifth; an inner metatarsal tubercle. Skin smooth above, granular beneath, on the throat minutely so. No dermal appendage on the hell. Habit robust, head broader than long, body rather heavy, slightly narrowed in the postaxillary region.

    Field trials were conducted in cabbage (Brassica oleracea var capitata), cauliflower (B oleracea var botrytis) and knol khol (B oleracea gongylodes) crops at two different locations in Karnataka State (India) to optimize the timing of insecticide applications to control the diamondback moth, Plutella xylostella, using sex pheromone traps. Our results indicate that applications of cartap hydrochloride as insecticide during a 12-24 h period after the pheromone traps had caught on average 8, 12 and 16 males per trap per night in cabbage, cauliflower and knol khol, respectively, were significantly more effective than regular insecticide sprays at 7, 9, 12 or 15 days after transplantation. This was demonstrated by estimation of the mean number of eggs and larvae per plant, the percentage of holes produced, as well as the marketable yield of the three crops at each location. A good correlation between the immature stages, infestation level, the estimated crop yield and the number of moths caught in pheromone traps was also found, indicating the usefulness of pheromone-based monitoring traps to predict population densities of the pest.

    Analyzing the phase transition from diffusive to localized behavior in a model of directed polymers in a random environment, this volume places particular emphasis on the localization phenomenon. The main question is: What does the path of a random walk look like if rewards and penalties are spatially randomly distributed? This model, which provides a simplified version of stretched elastic chains pinned by random impurities, has attracted much research activity, but it (and its relatives) still holds many secrets, especially in high dimensions. It has non-gaussian scaling limits and it belongs to the so-called KPZ universality class when the space is one-dimensional. Adopting a Gibbsian approach, using general and powerful tools from probability theory, the discrete model is studied in full generality. Presenting the state-of-the art from different perspectives, and written in the form of a first course on the subject, this monograph is aimed at researchers in probability or statistical physics, but is also ...

    This book addresses the emerging body of literature on the study of rare events in random graphs and networks. For example, what does a random graph look like if by chance it has far more triangles than expected? Until recently, probability theory offered no tools to help answer such questions. Important advances have been made in the last few years, employing tools from the newly developed theory of graph limits. This work represents the first book-length treatment of this area, while also exploring the related area of exponential random graphs. All required results from analysis, combinatorics, graph theory and classical large deviations theory are developed from scratch, making the text self-contained and doing away with the need to look up external references. Further, the book is written in a format and style that are accessible for beginning graduate students in mathematics and statistics.

Mais cela a-t-il toujours été le cas et surtout quelle a été la portée de leur action scientifique au XIXe siècle? Ce sont ces questions auxquelles l’article tente de répondre et cela de deux points de vue: d’une part en examinant la réception en France des thèses de ce que l’on a appelé l’Ecole historique française dans un temps où l’Ecole de l’exégèse exerce une domination sans partage; d’autre part, en observant les réactions allemandes devant cette production juridique historique française qui s’inscrit dans le courant savignien, observation basée notamment sur le dépouillement exhaustif de la Kritische Zeitschrift für Rechtswissenschaft und Gesetzgebung des Auslandes dirigée par Mittermaier. Que constate-t-on? Des deux côtés du Rhin, l’Ecole historique française a été étouffée. Ici, ses adeptes étaient accusés de pro germanisme; là, ils n’étaient finalement que les disciples de Savigny. Et pourtant leur action en faveur des sciences juridique et historique mérite pleinement qu’on voie en eux les fondateurs d’une véritable Ecole historique française du droit.

    Full Text Available Hypogean beetles that are protected or that require conservation measures in Catalonia Hypogean species are characterized by their profound adaptations to the adverse conditions of their subterranean habitats. Such specialization, however, makes them particularly vulnerable to alterations in their habitat. In the Autonomous Community of Catalonia several legislative tools have been developed to protect threatened invertebrates, and most beetle species included in Decree 328/1992 protecting Areas of Natural Interest in Catalonia (PEIN or considered in the future decree on the protection of Catalan invertebrates (CFAC are linked to subterranean habitats. In the present revision we compile regulations and other documents relating to the protection of beetle hypogean fauna in Catalonia. We provide updated faunistic and biogeographic data as well as information on the conservation status of the species, most of which are endemisms confined to a small area. Some of these species have been monitored in recent years by the Arthropod Department of the Natural Sciences Museum of Barcelona (in collaboration with the Catalan Biospeleology Association and the results of these studies are briefly discussed.

    Full Text Available In this paper, I want to present the personality of Robert Martin, whose works are not well known outside France, and analyse the important role he played in the early eighties for the revival of linguistics – considering at the same time the rising influence of his colleagues Bernard Combettes, Jean-Michel Adam and Michel Charolles, that is to say the influence they had on the introduction of text linguistics in France, specifically thanks to the creation in Metz of a new journal in the second part of the seventies: Pratiques. If Robert Martin first wanted to introduce natural logics in formal semantics, he was not insensible to the Prague School’s legacy either; but for him, the manner to introduce a discursive dimension or level in his linguistic model, that is to say a textual one between sentence and utterance, finally was a way to affirm and preserve the independence of semantics from pragmatics – the growing part of pragmatics in linguistics or the so called “language sciences” at the beginning of the same decade.

The species Cryptocarenus diadematus, Xyleborus affinis and Xyleborus retusus occurred as the dominant, very abundant, very frequent, yet only constant during the dry season, whereas during the rainy season Xyleborus affinis occurred clearly to be the extremely dominant, extremely abundant, extremely frequent and constant. During the dry season, the indexes of Equitability and Shannon-Wiener were more significant when compared with wet season.

    Full Text Available L’article part d’un paradoxe français à propos de la situation scolaire des enfants d’immigrés postcoloniaux. Les travaux statistiques ne montrent pas de disparités à leur encontre dans l’éducation de base, du point de vue des trajectoires, de la réussite au baccalauréat ou encore des sanctions reçues, alors que nombre d’observations qualitatives suggèrent le contraire. Le papier rappelle les travaux récents sur la question, publiés ou inédits, en les inscrivant dans le cadre d’une approche systémique contextualisée. Il discute notamment des processus d’ethnicisation des relations pédagogiques et de leur variabilité, ainsi que de l’ethnicisation des régulations supérieures à l’établissement (en reprenant la question du marché scolaire. Pour finir, il revient sur l’approche statistique de la discrimination institutionnelle ethnique, en notant qu’il s’agit d’un phénomène genré : les garçons issus des flux migratoires postcoloniaux sont spécifiquement défavorisés, tandis que les filles sont plutôt avantagées dans l’ensemble.School and ethnicity in France: a systemic contextualized approachThe paper starts from a French paradox concerning schooling of postcolonial immigrants’ children. Statistical studies do not find disparities against them in basic education, when one considers trajectories, final tests passing, or punishments, while qualitative literature often suggests the opposite. The paper reviews recent works on this issue, be they published or not, within a systemic contextualized framing. It discusses in particular shifting othering processes in pedagogical relationships and ethnicized ruling of the school system (the school market issue is revisited. Finally it returns to the statistical approach of ethnic institutional discrimination, and states that actually it is gendered: boys from postcolonial flows appear to be typically disadvantaged while peer girls are symmetrically rather advantaged.Escuela y etnicidad en Francia: una aproximación contextualizadaEl artículo toma como punto de partida lo paradójico de la situación escolar de los hijos de los emigrantes llegados a Francia después de la descolonización. Los estudios estadísticos no  permiten ver disparidades a nivel de la educación básica, ni a nivel de las trayectorias personales, del éxito en el bachillerato ni contabilizan las sanciones mientras que numerosos estudios cualitativos subrayan lo contrario. En el artículo se enumeran los estudios publicados o inéditos  recientes sobre este aspecto, inscribiéndolos en el marco de una aproximación sistémica contextualizada. Trata igualmente de los procesos de etnización de las relaciones pedagógicas y de la variabilidad así como de la etnización de las regulaciones a nivel superior en los centros (dentro del contexto del mercado escolar. La última parte del artículo trata de la aproximación estadística de la discriminación institucional étnica, subrayando el hecho de que se trata de un fenómeno « de género »: los hijos de inmigrantes están  desfavorecidos mientras que las hijas gozan de una situación más favorable.

    2007-12-01

    Full Text Available A comprehensive taxonomic catalogue of the Mexican representatives of the family Meloidae is presented. The catalogue includes a revised synonymical list including type localities and published geographical records for all known species. The Mexican Fauna of Meloidae currently includes 255 extant species, plus one only known from the fossil record, arranged in 21 genera within the subfamilies Meloinae, Nemognathinae and Tetraonycinae. The last comprehensive catalogue published (Blackwelder, 1945 recorded the presence of 160 species of Meloidae in México, almost 100 species less than the current known number. However the current number of species seems to be far below the actual number, since many species widely distributed along the northern border, within the United States, are likely to be found also in Mexico. Regarding taxonomic and nomenclatural changes, in this catalogue we propose the use of the names Epicauta dugesi Werner, 1957 and Tegrodera erosa extincta Beauregard, 1890; we propose three new synonymies for Nemognatha chrysomeloides (Linnaeus, 1763 (N. atra Beauregard, 1890; N. pallidicollis Beauregard, 1890 and N. violacea Beauregard, 1890 and one for E. dugesi (Epicauta tamara Adams & Selander, 1979; we designate lectotype for Lytta koltzei var. minor Haag-Rutenberg, 1880 with the goal of resolving the taxonomic problem generated by the previous invalid designation of lectotype for L. k. var. cyanescens; and finally we consider Cissites maculata (Swederus, 1787 and Tetraonyx (Tetraonyx bimaculatus (Klug, 1825 as species to be possibly excluded from the Mexican checklist.

En el último catálogo general, Blackwelder (1945 recogió la presencia en México de 160 especies de esta familia, casi 100 especies menos de las que se conocen en la actualidad y sin embargo, la cifra actual parece encontrarse aún lejos de la real, ya que existen muchas especies ampliamente distribuidas al norte de la frontera con los Estados Unidos cuya presencia es muy probable en territorio mexicano. En cuanto a la taxonomía y nomenclatura de las especies, en este catálogo se propone el uso de los nombres Epicauta dugesi Werner, 1957 y Tegrodera erosa extincta Beauregard, 1890; se incluyen tres sinonimias nuevas de Nemognatha chrysomeloides (Linnaeus, 1763 (N. atra Beauregard, 1890; N. pallidicollis Beauregard, 1890 y N. violacea Beauregard, 1890 y otra de E. dugesi (Epicauta tamara Adams & Selander, 1979; se designa lectotipo para Lytta koltzei var. minor Haag-Rutenberg, 1880 con el propósito de solucionar el problema taxonómico generado tras la designación inválida de lectotipo de L. k. var. cyanescens; y finalmente se consideran como especies posiblemente a excluir del listado de Meloidae de México a Cissites maculata (Swederus, 1787 y Tetraonyx (Tetraonyx bimaculatus (Klug, 1825.

    Full Text Available Após a expedição do Challenger (1872-1878, outras nações começaram a interessar-se pela pesquisa oceanográfica e a organizar suas próprias expedições. Desde 1885 que o príncipe Albert I de Mónaco realizava campanhas oceanográficas, com a colaboração de alguns dos melhores cientistas em biologia marinha e em oceanografia física, inventando técnicas e instrumentos para a realização dos trabalhos oceanográficos. A atividade científica do príncipe Albert certamente contribuiu para estimular o interesse do seu amigo, o rei dom Carlos I de Portugal, pelo estudo dos oceanos e da vida marinha. Ambos compartilhavam a necessidade de usar a fotografia para documentar suas pesquisas. Este artigo analisa o papel da fotografia científica na ciência oceanográfica, particularmente nas expedições realizadas pelo monarca português.

O delineamento estatístico utilizado foi inteiramente ao acaso com quatro repetições e arranjo fatorial 3 x 5, constituído por três concentrações do extrato e cinco períodos de exposições dos extratos (5, 10, 15, 20 e 25 minutos. Utilizaram-se frutos secos triturados de P. nigrum para extração em percolador com solvente álcool etílico (70, 50 e 30%. Os extratos foram aplicados na forma de vapor, por meio de um compressor adaptado, para dentro de recipiente contendo 100 insetos. Os resultados permitiram concluir que a mortalidade dos insetos aumenta com o aumento do período de exposição aos extratos, e que todas as concentrações se mostraram eficientes, embora, em termos de valores absolutos, o extrato com 70% de álcool etílico foi o mais eficaz.Considering the damage caused by the insect pest Callosobruchus maculatus (Fabr., 1775 to stored Vigna unguiculata Walp beans, this work aimed to evaluate the effectiveness of extracts of Piper nigrum L. in the control of adults of the referred species. The statistical outline used was made at random with four repetitions and factorial arrangement 3 x 5, formed by three concentrations of the extract and five periods of exposure to the extracts (5, 10, 15, 20 and 25 minutes. P. nigrum grounded dry fruits were used for extraction , which was done with ethyl alcohol (70, 50 and 30%, using a percolator. The extracts were applied as steam, using an adapted compressor into a container having 100 insects. By the results it was possible to conclude that the mortality of the insects becomes higher as the period of exposure to the extracts is increased, and that all the concentrations were shown to be effective, although, in terms of absolute values, the extract with 70% of ethyl alcohol was the most effective one.

    Full Text Available Os propósitos do estudo foram: 1 apresentar valores de referência percentílica às quatro provas da bateria de testes KTK; 2 comparar o desempenho coordenativo entre crianças vouzelenses e de outros estudos do país e exterior; e 3 apresentar pseudo-curvas de velocidade para cada prova. Foram avaliadas 811 crianças com idades entre os seis e os 10 anos. O desempenho coordenativo foi estimado por meio da bateria KTK. Cartas percentílicas e pseudo-curvas de velocidade foram construídas com base no método LMS, implementado no "software" LMSchartmarker Pro versão 2.54. Os valores de referência percentílicas expressam forte variabilidade interindividual do desempenho coordenativo. Em geral, os valores médios vouzelenses são inferiores aos belgas e alemães. O comportamento do percentil 50 das quatro provas do KTK é similar entre Vouzela, Peru e Açores. As pseudo-curvas de velocidade sugerem especificidade em cada prova e sexo, bem como diminuição dos ganhos coordenativos ao longo da idade.The purposes of this study were 1 to construct reference values to KTK test battery; 2 to compare Vouzela children’s motor coordination with those from other Portuguese sites and international references; 3 to present pseudo-velocity curves for each KTK test. The sample comprises 811 children aged six to 11 years. Motor coordination was assessed with the four tests of the KTK Battery. Centile charts were constructed using the LMS method implemented in LMSchartmarker Pro software. Pervasive interindividual differences were noted in all coordination tests. Mean values of Vouzela children’s motor coordination were lower than German and Belgian samples. 50th percentile was similar among Vouzela, Peruvian and Azorean samples. Pseudo-velocity curves suggested a marked specificity to each test and sex, as well as decreasing of the coordinative gains per year.

    A theoretical substantiation of the Cole-Cole, Cole-Davidson and Havriliak-Negami types of susceptibilities is presented. These types of susceptibility are shown to be a manifestation of weak nonlocality and nonlinearity. The Debye susceptibility corresponds to linear and local relaxation, the Cole-Cole susceptibility being linear and nonlocal; the Cole-Davidson susceptibility is nonlinear and local and the Havriliak-Negami susceptibility corresponds to nonlinear and nonlocal relaxation.

    Full Text Available Las estrategias de conservación en Chile han analizado la diversidad de nuestro país en base a información de especies grandes, carismáticas, paraguas y poco abundantes. Actualmente, nuestro interés ha estado dirigido a analizar la información de invertebrados para definir áreas de endemismo, áreas prioritarias para conservación y áreas naturales importantes desde el punto de vista filogenético. El lucánido Chiasognathus granti es una especie emblemática para la entomología chilena. Este trabajo es pionero en evaluar el estado de conservación de esta especie en Chile, para lo cual fueron calculados los índices de prioridad de conservación (SUMIN y CPI en base a literatura especializada, colecciones de referencia y prospecciones en terreno. C. granti es considerada una especie Rara, de acuerdo al índice de SUMIN y Vulnerable, de acuerdo al índice CPI. Nosotros concluimos que C. granti puede ser considerada Vulnerable en Chile con una alta probabilidad de extinción, hecho que podría afectar la sobrevivencia de las poblaciones presentes en Argentina.Based on information of large body size, charismatic, umbrella and Rare species, the Conservation strategies have analyzed the diversity of Chile. Define endemism areas, priorities conservation areas and geographic areas with high phylogenetic value has been the aims of our studies in beetles. An emblematic species for the Chilean entomologic community is the stag beetle C. granti. We assign priorities for the conservation of C. granti through conservation priority indexes (SUMIN and CPI based on literature, reference collection and field studies. C. granti can be considered Rare by SUMIN index and Vulnerable by CPI index. We concluded that C. granti is Vulnerable with a high probability of extinction in Chile; this situation could affect the survival of populations in Argentina.

    Full Text Available RECEPTION AND TRANSFORMATION OF GEOGRAPHICAL IDEAS OF THE FRENCH GEOGRAPHY SCHOOL IN JAPAN - The main characteristics of the geography of Vidal de La Blache and of his school of thought were known in Japan until the early days of the 1940's, especially through the efforts made by a professor of the University of Tokyo, Koji Iizuka. French geography was considered in Japan as representative of human geography in the world. It was used to counter Japanese geography, which was held to be environmentalistic and deterministic under the strong influence of German geography. After the Second World War, French geography offered an antithesis to fascist geography or to geopolitics during the movement of democratization in Japan, when geography was categorized as one of the disciplines of the social sciences. Two major elements played a role in the reconstruction of Japanese geography: the Vidalism tradition of French geography and the Marxist scientific environment. From the middle of the 1950's, Japanese geographers took an interest in the methodologies of French regional geography, for exemple the important notion of way of life. Paradoxically, they never wrote original regional monographs of Japan.

    Full Text Available Se realiza un estudio de una comunidad de escarabajos coprófagos, en el Centro de Investigaciones Ecológicas de la Macarena (ClEM, acerca de las estrategias de coexistencia y dilución de la competencia interespecífica. Los diversos muestreos se efectuaron entre junio y julio de 1994, diciembre y enero de 1996, enero de 1998 y junio y julio de 1999, en la totalidad de los hábitats existentes para la zona. Se realizaron transectos con quince trampas de caída pittalf, separadas 25 m y 500 m entre sí. Las trampas fueron cebadas con excremento humane, con pescado en descomposición y con banano en descomposición, por espacio de 48 horas cada 10 días, en cada uno de los meses de muestreo. Adicionalmente se colocaron trampas de intersección, trampas tipo NTP80 y se colectaron individuos manualmente. Un total de 58 especies fueron encontradas, las cuales pertenecen a 15 géneros, 10 de los cuales son estrictamente endémicos para el neotrópico. El género mejor representado es Dichotomius can 10 especies, seguido par Canthon con 8 especies y Eurysternus y Canthidium con 7 cada uno. Se estudiaron cuatro mecanismos de dilución para los cuales se destaca especialmente un importante efecto en la asociación al tipo de hábitat, encontrando especies de Bosque maduro y especies típicas de Bosque inundable. También se observo una variable temporal asociada a una restricción en la actividad diaria, donde existen  especies nocturnas y diurnas. Otro factor es el tipo de especialización al recurso alimenticio, ya que se encontraron especies coprófagas, necrófagas y copronecrófagas. Finalmente se analizó el tipo de relocalización, presentándose tres grupos diferenciados que también diluyen la competencia interespecífica. La combinación de todos estos mecanismos  estudiados, afecta radicalmente el número de especies que llegan realmente a interactuar directamente en el recurso alimenticio, por lo que su existencia permite la complejidad y diversidad de este grupo para la localidad. Se aconseja la ampliación de los muestreos a lo largo del año, así como un estudio minucioso de la actividad diaria, realizando muestreos por 24 horas.

    Full Text Available The Choros Archipelago includes three islands: Choros, Damas and Gaviota and it is part of The Pingüino de Humboldt National Reserve. These insular ecosystems are within the Chilean transitional coastal (25°-32° S. Prior researches in the archipelago reported a species of Tenebrionidae (Coleoptera endemic to Choros island (29°15' S, 71°32' W described as Gyriosomus granulipennis Pizarro-Araya & Flores. The objective of this paper is to evaluate the vulnerability of this species in the archipelago through Conservation Priority Index (CPI, Environmental Ministery of Chile (MMA and Red List of IUCN. We concluded that G. granulipennis is Endangered by CPI index, and Vulnerable by MMA of Chile. Additionally, this species can be classiffied with Deficient Data (DD by IUCN because many of data are impossible or difficult to obtain for insects and can overestimate or underestimate the risk of extinction of this species. We consider important to monitoring the continuity of this species and the protection of habitat, for which we propose not allow access the tourists and eradication of European rabbit.El archipiélago de Los Choros, conformado por las islas Choros, Damas y Gaviota forma parte de la Reserva Nacional Pingüino de Humboldt y está situado dentro del desierto costero transicional de Chile (25°-32° S. Estudios recientes realizados en el archipiélago dan cuenta de una especie endémica de Tenebrionidae (Coleoptera de la isla Choros (29°15' S, 71°32' O descripta como Gyriosomus granulipennis Pizarro-Araya & Flores. El objetivo del presente trabajo es evaluar la prioridad de conservación de esta especie en el archipiélago mediante el análisis del Índice de Prioridad de Conservación (CPI, clasificación del Ministerio de Medio Ambiente (MMA de Chile y lista roja de la IUCN. Nuestros resultados sostienen que esta especie puede ser catalogada en categoría En peligro por el índice CPI y Vulnerable según el MMA. Según criterios IUCN esta especie debería ser categorizada con Datos Deficientes (DD, ya que muchos de los datos necesarios para la clasificación son difíciles de obtener para insectos o pueden sobrestimar o subestimar el riesgo de extinción de esta especie. Consideramos importante monitorear la continuidad de esta especie y conservarla a través del hábitat, para lo cual proponemos evitar el acceso a turistas y erradicar el conejo silvestre europeo.

    Full Text Available The conference entitled Le cinéma de Bergson: image, affect, mouvement took place from 16 to 18 May 2013 in Paris. At the beginning it sounds a little bit strange talking about "Bergson's cinema". In effect we all know that in several essays and in the final chapter of Creative Evolution (1907, Bergson employs what he calls the "cinematographical apparatus" as an analogy for how the intellect approaches reality. The cinema is like a metaphor for the fact that the intellect can only express movement – reality itself – in static terms. Anyway it's not a positive judgment. For this reason the real purpose of the conference is to see Bergson's theory of cinema from another point of view. Through the Deleuze's lecture we can discover a "new Bergson" as theorist of what Deleuze calls "ontology of images". In this way it could be possible talk about "Bergson's cinema", to imagine it, to dream it.

    NATURAL SCIENCES IN KINDERGARTEN: A SOCIO-COGNITIVE FRAMEWORK FOR LEARNING AND TEACHING - The present study presents a socio-cognitive framework for the construction of the scientific knowledge of natural phenomena among pre-school children and for the development of science activities at kindergarten. It involves elements from theories of social interaction; social psychology of development and cognitive functioning; and research in natural-science teaching methods which acknowledge the importance and fundamental role of social interaction in the development of cognitive operations and learning. The study also presents some of the more significant results of the research carried out on different aspects of this topic. The discussion unfolded here supports the hypothesis that the construction of natural-scientific knowledge at the pre-school age and corresponding scholastic activities are necessary and effective.

    Full Text Available The objectives of this study were to evaluate the performance of cultivars, to quantify the variability and to estimate the genetic distances of 66 wine grape accessions in the Grape Germplasm Bank of the EMBRAPA Semi-Arid, in Juazeiro, BA, Brazil, through the characterization of discrete and continuous phenotypic variables. Multivariate statistics, such as, principal components, Tocher's optimization procedure, and the graphic of the distance, were efficient in grouping more similar genotypes, according to their phenotypic characteristics. There was no agreement in the formation of groups between continuous and discrete morpho-agronomic traits, when Tocher's optimization procedure was used. Discrete variables allowed the separation of Vitis vinifera and hybrids in different groups. Significant positive correlations were observed between weight, length and width of bunches, and a negative correlation between titratable acidity and TSS/TTA. The major part (84.12% of the total variation present in the original data was explained by the four principal components. The results revealed little variability between wine grape accessions in the Grape Germplasm Bank of Embrapa Semi-Arid.Os objetivos deste trabalho foram avaliar o comportamento agronômico, quantificar a variabilidade e estimar as distâncias genéticas de 66 acessos de videira destinadas à elaboração de vinhos, presente no Banco de Germoplasma de Videira da EMBRAPA Semiárido, em Juazeiro-BA, Brasil, por meio da caracterização de descritores fenotípicos de variação contínua e discreta. As técnicas multivariadas utilizadas, componentes principais, método de otimização de Tocher e projeção gráfica das distâncias foram eficientes no agrupamento dos genótipos mais similares, de acordo com as suas características fenotípicas. Não houve concordância na formação dos grupos pelo método de otimização de Tocher, quando foram avaliadas características morfoagronômicas de variação contínua e discreta. A utilização de variáveis discretas permitiu a separação de Vitis vinifera e híbridos em grupos distintos. Correlações significativas positivas foram observadas entre peso, comprimento e largura de cachos, bem como correlação negativa entre acidez total titulável e relação SST/ATT. 84,12% da variação total presente nos dados originais foram explicados pelos primeiros quatro componentes principais. Os resultados obtidos demonstram que existe pequena variabilidade entre os acessos de uvas para vinho no Banco de Germoplasma da Embrapa Semiárido.

    Full Text Available Teaching the evolution of the living species, a key concept in modern biology, is today at the heart of many studies within the French and international educational systems, from primary school to university. It may indeed go against religious beliefs and thus stir up controversy. In some cases, these beliefs may even become an obstacle to the learning of this concept. A compulsory element in the French primary curriculum until 2008, it seems however that this concept hasn’t been given much importance in schools. Firstly, we shall study the official requirements in the primary curriculum and we shall identify institutional expectations. Secondly, a written questionnaire will aim to define the personal relationship primary teachers in Keystage 3 (year 4, 5, 6 at primary level and student teachers have with the concept of evolution, inside and outside the classroom, and how this relationship might influence their decision to teach or not evolution, or the way they would teach it (Mairone, 2007; Mairone & Dupin, 2007, 2008. Thirdly, a written questionnaire submitted to Keystage 3 pupils will enable us to disclose their representations on the questions of the emergence and evolution of the living species; it will help to define learning barriers and appropriate didactic engineering. This is the subject of this proposition. This whole study is meant to make recommendations for teaching/learning of evolution of living species for primary school and for teachers training.

    Full Text Available The qualitative and quantitative losses caused by stored product insects are of great concern, and since there is only a few active ingredients available for their control it is very important to have a frequent insect resistance monitoring. The objective of this research is to evaluate combination of bioassays and molecular marker techniques to detect insecticide resistance in stored product beetles. The Coleoptera species used for the tests were Sitophilus oryzae (L. (Curculionidae, Rhyzopertha dominica (F. (Bostrichidae and Oryzaephilus surinamensis (L. (Silvanidae. For the bioassays it was used the impregnated filter paper technique, applying 1 mL of deltamethrin (K-Obiol 25 CE TM using four concentrations and five replicates, including a control with solvent only. Ten adults of each species were liberated separately on each dish. The mortality was evaluated after 24 h and resistance determined by probit analysis. The samples used for the PCR-RAPD were either in vivo or preserved in 70% ethanol, kept in -18°C freezer. After extraction, quantification and DNA quality analysis, the 25 µL samples had the DNA amplified and tested with six primers. The bioassays showed a crescent mortality proportional to insecticide concentration. The resistance factor for R. dominica, S. zeamais and S. oryzae were: 2,2; 3,2 and 9,2, respectively, compared to the susceptible populations of each species. The PCR-RAPD analysis revealed bands which indicate inter and intraspecific variability in the populations, but it was not possible to correlate them to resistance. The association of bioassay and PCR-RAPD represents a precise and valuable tool for resistance management of stored product insects, but more populations and primers should be tested.

    Leila Beatriz Ribeiro

    2011-01-01

    Full Text Available On the basis of the "Urbano" strips, this article discusses the collections of "useless" objects in a context of heritage and social memory. In the various collections of "useless things", the memories evoked by the objects - many of them biographical - are mirror specular and subjective relations to the re-ordered world of "Urbano". They are transformed into possibilities of power and experience of a renewed life for himself and for the group around him. Travelling to places through postcards; sharing with the living statue on the square the songs from his collection of music boxes, etc. are ways of narrowing, of affirmation of an identity and of "a peaceful impression of continuity". This impression is reinforced by the "company of the things that become old together with us", according to Bosi (2009, p. 441, since the collection has the power to represent the individual, making the object to be perpetuated as a link between the individual and the world around him. Under the informational perspective, these representations provide ways of reading within a larger picture of the Brazilian society, viz. the retired elderly. Why should we not see the collectionist practice of "Urbano" as a metaphor of resistance to disposal, as a criticism of consumer attitudes, of the death of things? If old age and retired people are social categories, why should we not relate "Urbano's" objects, subject to disposal, with some representations of old age and of retired people as unproductive?

    Full Text Available Los sistemas lóticos integrados por cauces temporales representan una alta proporción de las aguas continentales del planeta, no obstante se encuentran entre los sistemas menos estudiados a nivel mundial. En cuanto a diversidad entomológica, el centro de México -donde se ubican estos sistemas- permanece poco estudiado a pesar del alto potencial que presenta la zona de albergar una alta diversidad y de los vínculos importantes que este grupo desempeña en los flujos de energía de los ecosistemas acuáticos. El objetivo del presente trabajo fue analizar las variables ambientales que determinan los cambios en la diversidad y las escalas en que tienen efecto, en las comunidades de insectos acuáticos de un sistema fluvial semiárido del centro de México. Se registraron un total de 89 géneros, con el orden Coleoptera presentando la mayor riqueza. Los valores más altos de diversidad alfa se encontraron sobre sitios permanentes en la temporada de sequía (¹D:10.63, lo que se atribuye a la mayor estabilidad que presentan los sistemas fluviales en esta temporada. Las comunidades establecidas sobre cauces permanentes e intermitentes presentaron baja similitud (Ij <0.45, indicando un alto recambio entre comunidades establecidas sobre cauces con diferente hidroperiodo. Los análisis de distribución (“partición” de la diversidad indican que el mayor aporte a la diversidad regional se da por cambios en la composición de géneros a nivel de ríos (37%, entre temporadas (22% y por el tipo de sistema (21%. De acuerdo con el Análisis de Correlación Canónica las variables de mesohábitat, velocidad de corriente, calidad ecológica y orden del cauce son las que mejor explican la variación en la presencia de los taxones.

    Full Text Available The first records of the three known species of Oxycraspedus Kuschel (Belidae: Oxycoryninae in Argentina are reported, and added to their known distribution in Chile. These weevils are of interest because of their association with the pehuén or monkey puzzle tree, Araucaria araucana, a species of conservation concern. Their distribution data are of value for the protection of biodiversity in natural areas of Patagonia.

    2017-10-01

    Seeing that about 70% component of fresh biological tissues is water, many scientists try to use water models to describe the dielectric properties of biological tissues. The classical water dielectric models are Debye model, Double Debye model and Cole-Cole model. This work aims to determine a suitable model by comparing three models above with experimental data. These models are applied to fresh pork tissue. By means of least square method, the parameters of different models are fitted with the experimental data. Comparing different models on both dielectric function, the Cole-Cole model is verified the best to describe the experiments of pork tissue. The correction factor α of the Cole-Cole model is an important modification for biological tissues. So Cole-Cole model is supposed to be a priority selection to describe the dielectric properties for biological tissues in the terahertz range.

    2015-01-01

    In Knowledge Machines, Eric Meyer and Ralph Schroeder argue that digital technologies have fundamentally changed research practices in the sciences, social sciences, and humanities. Meyer and Schroeder show that digital tools and data, used collectively and in distributed mode -- which they term e-research -- have transformed not just the consumption of knowledge but also the production of knowledge. Digital technologies for research are reshaping how knowledge advances in disciplines that range from physics to literary analysis. Meyer and Schroeder map the rise of digital research and offer case studies from many fields, including biomedicine, social science uses of the Web, astronomy, and large-scale textual analysis in the humanities. They consider such topics as the challenges of sharing research data and of big data approaches, disciplinary differences and new forms of interdisciplinary collaboration, the shifting boundaries between researchers and their publics, and the ways that digital tools promote o...

    Full Text Available Objective – The objective of the study was to explore how teachers in the United Kingdom use research literature to inform their practice. Special emphasis was given to the effect of the teachers’ information literacy and their level of ready access to research information.Design – This study was primarily a qualitative study utilizing mixed methods, including individual interviews, focus groups (“literature review groups”, and an online discussion forum. Qualitative data was supplemented by a questionnaire survey.Setting – The qualitative portions of the study took place in the United Kingdom across five education authorities; however, it is unclear where these authorities were geographically. The survey was distributed across Scotland, England, and Wales. The study was conducted during 2002 to 2003. Subjects – Nursery, primary, and secondary teachers, school librarians, school library systems, and education authority advisors (EA in the United Kingdom. Methods – The 28 interviews (54% primary teachers, 39% secondary teachers, 7% special education and four focus groups (each with three to five participants; 15 participants in total, including teachers at various levels from primary, secondary, and nursery schools were conducted with volunteers from a random sample across five education authorities. Recruitment was done by sending written materials to schools. Those interviewed represented five authorities. Focus groups were conducted in just four authorities. It is not clear when the individual and group interviews were conducted (time of day and year. Volunteers were given the option to receive funding for a substitute teacher in order to participate, though none took advantage of this offer. The interview process used a vignette technique to elicit teachers’ attitudes to a situation in a non-threatening way. Interviewees were asked to comment on two situations that might make them seek information. One was adding a new subject or new aspect of an existing subject into the classroom. The second dealt with a “new pedagogical challenge.” Though the topics of the vignettes were provided, the exact way the topics were presented was not. They were asked how they would advise another teacher in these situations then relate their thoughts to a real situation they had faced. Interviews were about one hour in length. Twenty-five of the 28 interviews were taped and transcribed verbatim. Extensive notes were made for the other three. Transcripts and notes were analyzed using QSR N4 Classic content analysis software. Themes related to information literacy and information seeking, including barriers, were noted. Four literature response groups were given examples of research information (journal articles, reports, etc related to information computer technology (ICT and class size. Each topic had information from various evidence levels and included both print and electronic format. Again, the discussion topics were provided in the article, but the exact way the topics were presented was not. Over 2 to 2.5 hours, teachers read the materials, made notes, and discussed the information as a group. For the ICT information, groups were asked to discuss presentation of the information. For the class size information, groups were asked to discuss content of the materials. Discussions were transcribed verbatim and analyzed with the content analysis software. A total of 3899 questionnaire surveys were distributed to teachers (3000, head teachers (500, school librarians (250, education authority advisors (100, and school library systems (49. Response rate was exceptionally low in the teacher and head teacher categories, with only 10.9% of teachers and 15.6% of head teachers responding. Response rates in other categories ranged from 31.2% to 55%, with the highest response rates from education authorities and school library systems. The survey served to gain an understanding of attitudes about using research in practice across a broad spectrum of stakeholders. The survey instrument itself, which was not provided in the article, was piloted prior to the study, but there is no mention of reliability or validity analysis. To supplement study data, participants who had stated they would be interested in participating in an online discussion were sent preliminary findings and asked to comment on themes using the online discussion forum. Only 21 posts were gathered using this method. Overall, the methods used in this study are appropriate for the questions that were posed in the article. Qualitative studies are useful for gathering data where little is known and where more data would help identify possibly hypotheses for further study.Main Results – Teachers in this study relied on a small set of resources and preferred what was readily available at their ownschool. These teachers most frequently used colleagues, in-service events, the Internet, newspapers, and reports typically found in schools as sources of information. Sources that information professionals would consider quality evidence were rarely mentioned. These teachers also tended to prefer sources that present information in a practical context. Not surprisingly, time was identified as a major barrier to accessing research information in addition to limited access to resources. The Internet was identified as the preferred point of access, citing ease of use, speed, and convenience as the reasons for this preference. Comments suggested a preference for synthesized information sources. Teachers indicated they felt the responsibility for disseminating research information fell on head teachers and EA. They also noted that access to information from their own school library was a problem. They felt librarians and libraries in schools were meant for students, not for teachers, and also expressed that school libraries typically did not provide access to research. Comments suggested that the structure of teaching in a classroom itself does not allow teachers to use information as is needed for evidence-based practice. There were concerns expressed about lack of school library funding available to supply research evidence needed by teachers. School librarians and school library services respondents did indicate that they provide abroad range of services aimed at teachers, such as alerts to literature, information skills training, and advice on resources. However, their sources of research for teachers were limited in nature. Librarians indicated that teachers did not ask for research information, but if demand were there, they could respond accordingly. Teacher comments suggest that librarians might want to consider being more proactive in distributing information. Though teachers expressed high confidence in their abilities to find information, comments about search habits and practices contradicted this. Most remarks suggested searching techniques that were not sophisticated or showing higher levels of information literacy competency. The respondents were concerned with evaluating the quality of information sources but found this appraisal to be more difficult if the authors did not explain the impact or change in practice that should come from the findings. The participants in this study were likely biased toward using research information more than other teachers. This is an important limitation that the authors do address. Additionally, the response rate for the survey was quite low for the teacher subset. Despite this limitation, data from the questionnaire was used appropriately to confirm and clarify data from the qualitative portions of the study.Conclusion – In order for teachers to appreciate the value of quality research evidence enough to regularly seek it out and place it into practice, a culture of evidence based practice must be embraced and supported by their school authorities. This study indicates significant potential for school librarians and systems to support this culture through proactive dissemination of research, provision of local access to materials, and education related to information literacy. School librarians must evolve from their typical student-centric role to accomplish this.

    Full Text Available The research on plant genetic resources is essential for the conservation of genetic diversity and accessions' divergence studies, as a basis for plant breeding. Aiming to know the state of art in this subject, a historical survey was carried out in Revista de Olericultura and in Horticultura Brasileira, from 1961 to 2006, searching for papers dealing with vegetable crops genetic resources. In each of the papers, the species studied, first author institution, publication year, applied software, number of accessions and descriptors, and the multivariate techniques used were registered. Based on these characteristics, papers were grouped using multivariate analysis. Sixty-one papers dealt somehow with genetic resources in the time covered by the survey, from which 91.8% were published after 1990 (60.7% from 2001 to 2005. The use of multivariate analysis was reported in 57.3% of the papers, with an average of 2.3 and maximum of 6 multivariate procedures per paper. The Tocher Method, reported in 34% of the papers, was the most frequently used multivariate analysis. Twenty-five species were studied. Capsicum was the most frequently studied genus, either considering number of papers (seven or accessions (664. Research institutions located in the Southeast region concentrated the highest number of papers. UFV (Federal University of Viçosa, UENF (North Fluminense State University Darcy Ribeiro, Embrapa Vegetables, and UNESP (São Paulo State University Campus of Jaboticabal responded for 45% of the papers. There was an improvement in the adequacy of the statistical techniques used along time, due mainly to the development of free-access software. The software Genes was the most frequently reported in the papers surveyed. Nevertheless, almost 50% of the authors did not mention the software used for data analysis. Quantitative morphoagronomic and evaluation descriptors were the most often used. The multivariate analysis allowed grouping the papers in nine clusters.A pesquisa com recursos genéticos vegetais é essencial tanto para a conservação da diversidade genética, quanto para o estudo da divergência entre acessos, base para programas de melhoramento. Com objetivo de conhecer o estado-da-arte nesse tema, foram identificados os trabalhos relacionados a recursos genéticos de hortaliças publicados na " Revista de Olericultura" e " Horticultura Brasileira" , de 1961 a 2006. Foram anotadas as espécie(s estudada(s, a instituição de origem do primeiro autor, o ano de publicação, os softwares utilizados, o número de acessos, o número de descritores e o número de técnicas multivariadas aplicadas em cada artigo. Com base nessas caraterísticas, os artigos foram agrupados utilizando análise multivariada. No período pesquisado, 61 artigos trataram, sob algum aspecto, de recursos genéticos. Desses, 91,8% foram publicados a partir de 1990, com concentração de 2001 a 2005 (60,7%, com 57,3% deles utilizando pelo menos uma técnica multivariada, com média de 2,3 e máximo de seis técnicas por artigo. O método de agrupamento de Tocher foi o mais utilizado, relatado em 34% dos artigos. Os artigos cobriram 25 espécies. Dentre elas, Capsicum foi o gênero mais pesquisado, tanto em relação ao número de artigos (sete, quanto em número de acessos estudados (664. As instituições de pesquisa da região Sudeste concentraram o maior número de artigos. Se somadas, UFV, UENF, Embrapa Hortaliças e UNESP Campus de Jaboticabal foram responsáveis por 45% dos trabalhos publicados no tema. Houve um aprimoramento das técnicas estatísticas utilizadas na análise dos dados, sobretudo devido ao desenvolvimento e uso de softwares de fácil compreensão. O programa GENES foi o mais referenciado. Entretanto, quase a metade dos autores não citou o programa estatístico utilizado para a análise dos dados. Os descritores de caracterização morfoagronômica quantitativos e de avaliação foram os mais estudados. A análise multivariada permitiu classificar os artigos em nove grupos.

    Habitat loss and fragmentation are considered as the main causes of biodiversity depression. Habitat loss implies a reduction of suitable habitat for organisms, and habitat fragmentation is a change in the spatial configuration of the landscape, with the remaining fragments resulting more or less isolated. Recent theory indicates that the effects of habitat loss are more important than those of habitat fragmentation, however there are few experimental studies evaluating both processes separat...

    Full Text Available Lodges founded by French, Italian and Spanish obediences in Eastern Mediterranean countries: Turkey, the Middle East and Magreb countries, started schools that were qualified as “masonic” “secular” o “Free secular”. These obediences were in conflict, in this regard, with Christian congregations, with moslem ones, and, in some cases, with the synagogues. This paper deals more specifically with some schools built by the French and Italian obediences in the Ottoman Empire, at the turn of the 19th century confronting them with the schools in the Middle East and the Magreb belonging to these same obediences as well as by the Grande Oriente Español. It is important for us to question the terms the freemasons used to refer to those schools. Whether it was common usage to present them, at the end of the 19th century, as “secular schools”, instead of calling them “masonic schools”, which was generally their first title/name, thus revealing that the educational Project should have elements of masonic morality and of masonic ideals.

    Full Text Available A infecção por Herpes simplex vírus (HSV é causa freqüente de inflamação intra-ocular ou uveíte anterior. A hipertensão ocular é característica comumente observada nas ceratouveítes herpéticas. Neste relato descrevemos o acúmulo de fluido e descolamento do "flap" corneano da ceratomileusis, no pós-operatório tardio de LASIK (28 meses, associado a quadro hipertensivo ocular secundário a ceratouveíte herpética. Este achado corrobora a suposição que a cicatrização corneana após LASIK seja apenas parcial e o espaço virtual produzido pela ceratomileuisis permaneça indefinidamente. Condições de aumento excessivo da pressão intra-ocular podem causar edema corneano com acúmulo de fluido da interface.Herpes simplex virus infection is a frequent cause of intraocular inflammation or anterior uveitis. Ocular hypertension is a common feature in herpetic keratouveitis. We describe a fluid accumulation and flap displacement in late postoperative period (28 months of LASIK associated with ocular hypertension caused by herpetic keratouveitis. This finding supports the theory that flap attachment after LASIK is only partial and the virtual space remains indefinitely. The presence of ocular hypertension may lead to corneal edema and fluid accumulation in the interface.

Os padrões mais importantes são o AACR2, MARC/XML, norma ISO2709 e protocolo de comunicação z39.50. A aderência a estes padrões influi nos custos finais do projeto. O custo de construção da base de dados bibliográfica pode ser o elemento mais caro do projeto, com diminuição de custos com uso dos padrões e dos recursos informacionais disponibilizados gratuitamente na Internet. Quanto maior o acervo, mais expressiva é a economia conseguida com esta metodologia, sem prejuízo das diretrizes locais na construção da base.

    Full Text Available Awareness with respect to others is strictly related to the type of interpersonal relations which persons maintain within a given culture. However, this awareness can also show certain deficiencies in modern societies (Augé, 1994. In this case, the school may have a role to play with respect to rehabilitating this awareness, that is, enhancing the attention given to others. First and foremost, group methods appear quite well suited to answer these expectations. There really are reasons for the development of student skills other than classical social abilities (knowing how to listen to their work partners, being able to work together with them, etc.. From this point of view, the social/emotional track appears to be quite promising, from a social-constructivist perspective.

  8. Evaluation method for corrosion level of rebar in RC with electrical impedance measurement

    Science.gov (United States)

    Sasamoto, Akira

    2018-04-01

    The author reported that the impedance measurement using the 4-terminal method on the RC surface for diagnosing corrosion of internal rebar. The difference between the maximum value at 0.01 Hz and the minimum value around 10 Hz indicates the corrosion level of rebar in that report. This is successive report on a signal processing method for estimating the corrosion level by the measured impedance data to obtain more high accuracy. In the dielectric, a graph of frequency and dielectric constant (Cole-Cole plot diagram by KS Cole and RH Cole article of 1941) draws a shape of circle if the dielectric is independent of frequency but it draws a shape of ellipse in reality due to frequency dependency. Havriliak and Negami have also presented Havriliak-Negami model which introduced parameter into dielectric constant equation which deforms Cole-Cole plot diagram and showed that acquired dielectric data of polymer materials fit to this model with proper parameters. In this report, we first consider electric model connected with resistance and capacitance as a rough model of RC concrete. If the capacitance in this model circuit has some loss of dielectric, it is stated that graph in impedance plot is expected to take as similar deformation in the dielectric Cole-Cole plot. Then a numerical optimization computer code for obtaining parameters in the Cole-Cole plot diagram and Havriliak-Negami model is constructed, and the correlation between the deformation parameter of each model and corrosion is shown by this code. These results are feasibility study for diagnosis of corrosion level of rebar by associated parameters to a shape of impedance graph.

  20. Psychophysical estimates of cochlear phase response: masking by harmonic complexes.

    Harmonic complexes with identical component frequencies and amplitudes but different phase spectra may be differentially effective as maskers. Such harmonic waveforms, constructed with positive or negative Schroeder phases, have similar envelopes and identical long-term power spectra, but the positive Schroeder-phase waveform is typically a less effective masker than the negative Schroeder-phase waveform. These masking differences have been attributed to an interaction between the masker phase spectrum and the phase characteristic of the basilar membrane. To explore this relationship, the gradient of stimulus phase change across masker bandwidth was varied by systematically altering the Schroeder-phase algorithm. Observers detected a signal tone added in-phase to a single component of a masker whose frequencies ranged from 200 to 5000 Hz, with a fundamental frequency of 100 Hz. For signal frequencies of 1000-4000 Hz, differences in masking across the harmonic complexes could be as large as 5-10 dB for phase gradients changing by only 10%. The phase gradient that resulted in a minimum amount of masking varied with signal frequency, with low frequencies masked least effectively by stimuli with rapidly changing component phases and high frequencies masked by stimuli with more shallow phase gradients. A gammachirp filter was implemented to model these results, predicting the qualitative changes in curvature of the phase-byfrequency function estimated from the empirical data: In some cases, small modifications to the gammachirp filter produced better quantitative predictions of curvature changes across frequency, but this filter, as implemented here, was unable to accurately represent all the data.

For example, the global financial crisis in 2008 led to a fall of natural gas consumption in OECD countries. However, the exploitation of unconventional hydrocarbon resources, such as shale gas, in the United States has significantly increased gas consumption again, showing strong economic, environmental, and political implications that challenge the energy sec...

    Full Text Available Due to a series of misconceptions about science, science centers and science museums have proposed projects to break the paradigm of science education focused on a small portion of the population. These centers and museums have developed strategies aimed at social inclusion in terms of their educational character, thereby investing in strategies to upgrade vocational education, among other actions. However, most of these areas are concentrated in large urban areas, preventing the participation of the poorest sectors of society. Thus, this study shows a report of a pilot teacher education program developed by the Espaço Ciência InterAtiva do IFRJ, a science museum located in a suburban area of Rio de Janeiro, showing that a scientific exhibition can contribute to the inclusion of teachers in these areas of informal education, and to their ongoing training.En raison d’un ensemble de conceptions erronées sur la science, les centres et les musées des sciences se proposent actuellement de rompre avec l’image de la science réservée à une petite partie de la population. Ces espaces développent des activités qui, par leur caractère éducatif, favorisent l’intégration sociale, et investissent de cette façon, entre autres actions, dans des stratégies de mise à niveau des professionnels de l’éducation. Toutefois, la plupart de ces espaces se concentrent dans les grands centres urbains, ce qui rend la participation des couches moins favorisées de la société bien plus difficile. Ainsi, ce travail porte sur l’exposé d’un programme pilote de formation continue des enseignants, développé par l’Espaço Ciência InterAtiva (Espace Science Interactive de l’IFRJ1 - un musée des sciences situé dans une région périphérique de Rio de Janeiro, et démontre qu’une exposition scientifique peut contribuer à l’insertion d’enseignants dans ces espaces d’éducation non formelle ainsi qu’à leur formation continue.En virtud de una serie de conceptos equivocados respecto a la ciencia, los centros y museos de ciencias surgen con propuestas para romper con el paradigma de la ciencia accesible solo a una pequeña parte de la población.

  5. Extraction of electrical characteristics from pixels of multifrequency electrical impedance tomographs

    1996-01-01

    Full text: Multi-frequency electrical impedance tomography (MFEIT) is a modality that provides images of the change in the electrical response of tissue at a number of discrete frequencies relative to the response at a selected reference frequency (H Griffiths and A Ahmed, Clin. Phys. Physiol. Meas. 8A:103-107, 1987). This method overcomes the need, when forming in vivo static images, to measure or calculate the voltage profiles of a resistive, homogeneous reference medium and therefore avoids the errors introduced due to boundary shape and electrode location inaccuracies. Information on the spectral response of the tissue is contained within the pixel values, hence characteristics of the tissues and the state of health can be obtained by extracting this information from in vivo MFEIT images. Griffith and Jossinet (Physiol Meas. 15A: 59-63, 1994) used computer modelling to demonstrate that the Cole-Cole plot (variations of resistance and reactance with frequency) can be extracted from pixel values of MFEIT images provided the reference set was obtained from a purely resistive and homogeneous medium. To date it has not been possible to extract true Cole-Cole plots from in vivo MFEIT images because tissue contains a reactive component of impedance which introduces an unknown phase angle into the reference data set. Instead, an impedance spectrum, equivalent to a Cole-Cole plot rotated about the origin by the unknown phase angle, may be extracted. A correction for this rotation of the Cole-Cole plot is necessary since parameters derived from the impedance spectrum do not accurately reflect the electrical response of the imaged tissue. We have developed two distinct methods to determine this unknown phase angle and hence enable the extraction of parameters that more accurately reflect the true electrical response of tissue from in vivo MFEIT images. The first method is an empirical method based on observation of the distribution of frequency data around the Cole-Cole

    With the help of broadband dielectric spectroscopy in a wide temperature and frequency range,the conductivity spectra of ZnO polycrystalline ceramics are measured and the direct-current-like (DC-like) conductivity and relaxation polarization conductivity are observed successively along the frequency axis.According to the classical Debye theory and Cole-Cole equation,the physical meanings of the two conductivities are discussed.It is found that the DC-like conductivity corresponds to electron transportation over the Schottky barrier at the grainboundary.The relaxation polarization conductivity corresponds to electronic trap relaxation of intrinsic point defects (zinc interstitial and oxygen vacancy).When in the high frequency region,the relaxation conductivity obeys the universal law with the index n equal to the index α in the Cole-Cole equation as an indictor of disorder degree.

    Full Text Available The AC complex impedance spectroscopy technique has been used to obtain the electrical parameters of polycrystalline sample of (Ba0.85Ca0.15(Ti0.9Zr0.1O3 in a wide frequency range at different temperatures. This sample was prepared by a high temperature solid-state reaction technique and single phase formation was confirmed by X-ray diffraction technique. This study was carried out by the means of simultaneous analysis of impedance, modulus, and electrical conductivity. The Cole-Cole (Nyquist plots suggest that the grains and grain boundaries are responsible in the conduction mechanism of the material at high temperature. The ColeCole (Nyquist plot studies revealed the presence of grain and grain boundary effect at 485 °C. On the other hand, it showed only the presence of grain boundary component of the resistivity at 535 °C. Complex impedance analysis indicated the presence of non-Debye type dielectric relaxation. The bulk resistance of the material decreases with rise in temperature similar to a semiconductor, and the Cole-Cole (Nyquist plot showed the negative temperature coefficient of resistance (NTCR character of (Ba0.85Ca0.15(Ti0.9Zr0.1O3. The value of activation energy is found to be 0.7433 eV, which suggests that the conduction may be the result of defect and charge carriers present in the materials.

    This paper proposes a measurement method for complex resistivity using both current and potential waveforms. This method was applied to actual data. Especially, chargeability was discussed among complex resistivities. A method was proposed for determining the complex resistivity. At first, digital measurements of both current and potential waveforms were conducted. For the potential waveform, zero-order self-potential was canceled. Then, the FFT technique was applied to both current and potential waveforms, to determine both current and potential in the frequency domain. Hereafter, complex resistivity was determined through simple division. Since the inductive coupling was observed at higher frequencies, it was difficult to apply Cole-Cole model, simply. However, the inductive coupling could be removed using proper sampling frequency. Thus, a proper Cole-Cole dispersion curve could be obtained. Using this Cole-Cole dispersion curve, new chargeability could be defined. A linear relation between this chargeability and the ordinary time domain chargeability was made clear. 4 refs., 10 figs.

  5. 3-D time-domain induced polarization tomography: a new approach based on a source current density formulation

    Induced polarization (IP) of porous rocks can be associated with a secondary source current density, which is proportional to both the intrinsic chargeability and the primary (applied) current density. This gives the possibility of reformulating the time domain induced polarization (TDIP) problem as a time-dependent self-potential-type problem. This new approach implies a change of strategy regarding data acquisition and inversion, allowing major time savings for both. For inverting TDIP data, we first retrieve the electrical resistivity distribution. Then, we use this electrical resistivity distribution to reconstruct the primary current density during the injection/retrieval of the (primary) current between the current electrodes A and B. The time-lapse secondary source current density distribution is determined given the primary source current density and a distribution of chargeability (forward modelling step). The inverse problem is linear between the secondary voltages (measured at all the electrodes) and the computed secondary source current density. A kernel matrix relating the secondary observed voltages data to the source current density model is computed once (using the electrical conductivity distribution), and then used throughout the inversion process. This recovered source current density model is in turn used to estimate the time-dependent chargeability (normalized voltages) in each cell of the domain of interest. Assuming a Cole-Cole model for simplicity, we can reconstruct the 3-D distributions of the relaxation time τ and the Cole-Cole exponent c by fitting the intrinsic chargeability decay curve to a Cole-Cole relaxation model for each cell. Two simple cases are studied in details to explain this new approach. In the first case, we estimate the Cole-Cole parameters as well as the source current density field from a synthetic TDIP data set. Our approach is successfully able to reveal the presence of the anomaly and to invert its Cole-Cole

    Weighting patterns for loudness obtained using the reverse correlation method are thought to reveal the relative contributions of different frequency regions to total loudness, the equivalent of specific loudness. Current models of loudness assume that specific loudness is determined by peripheral...... processes such as compression and masking. Here we test this hypothesis using 20-tone harmonic complexes (200Hz f0, 200 to 4000Hz, 250 ms, 65 dB/Component) added in opposite phase relationships (Schroeder positive and negative). Due to the varying degree of envelope modulations, these time-reversed harmonic...... processes and reflect a central frequency weighting template....

    Germany's energy consensus talks, ongoing since March 1993, were brought to unsuccessful end on October 26. Representatives from the Social Democratic Party (SDP), led by Lower Saxony's prime minister, Gerhard Schroeder, failed to get approval from party leaders on continued development of advanced reactors with enhanced safety - notably the Siemens/Framatome-designed 1500-MWe European pressurized water reactor (EPR) plan, for which the prospective schedule envisages a construction start in 1998. Nor would the SDP leadership accept the continued operation of existing nuclear plans to the end of their design life (some 20 to 25 years)

    Full Text Available Due to a series of misconceptions about science, science centers and science museums have proposed projects to break the paradigm of science education focused on a small portion of the population. These centers and museums have developed strategies aimed at social inclusion in terms of their educational character, thereby investing in strategies to upgrade vocational education, among other actions. However, most of these areas are concentrated in large urban areas, preventing the participation of the poorest sectors of society. Thus, this study shows a report of a pilot teacher education program developed by the Espaço Ciência InterAtiva do IFRJ, a science museum located in a suburban area of Rio de Janeiro, showing that a scientific exhibition can contribute to the inclusion of teachers in these areas of informal education, and to their ongoing training.En raison d’un ensemble de conceptions erronées sur la science, les centres et les musées des sciences se proposent actuellement de rompre avec l’image de la science réservée à une petite partie de la population.

  16. 3-D Forward modeling of Induced Polarization Effects of Transient Electromagnetic Method

    Science.gov (United States)

    Wu, Y.; Ji, Y.; Guan, S.; Li, D.; Wang, A.

    2017-12-01

    In transient electromagnetic (TEM) detection, Induced polarization (IP) effects are so important that they cannot be ignored. The authors simulate the three-dimensional (3-D) induced polarization effects in time-domain directly by applying the finite-difference time-domain method (FDTD) based on Cole-Cole model. Due to the frequency dispersion characteristics of the electrical conductivity, the computations of convolution in the generalized Ohm's law of fractional order system makes the forward modeling particularly complicated. Firstly, we propose a method to approximate the fractional order function of Cole-Cole model using a lower order rational transfer function based on error minimum theory in the frequency domain. In this section, two auxiliary variables are introduced to transform nonlinear least square fitting problem of the fractional order system into a linear programming problem, thus avoiding having to solve a system of equations and nonlinear problems. Secondly, the time-domain expression of Cole-Cole model is obtained by using Inverse Laplace transform. Then, for the calculation of Ohm's law, we propose an e-index auxiliary equation of conductivity to transform the convolution to non-convolution integral; in this section, the trapezoid rule is applied to compute the integral. We then substitute the recursion equation into Maxwell's equations to derive the iterative equations of electromagnetic field using the FDTD method. Finally, we finish the stimulation of 3-D model and evaluate polarization parameters. The results are compared with those obtained from the digital filtering solution of the analytical equation in the homogeneous half space, as well as with the 3-D model results from the auxiliary ordinary differential equation method (ADE). Good agreements are obtained across the three methods. In terms of the 3-D model, the proposed method has higher efficiency and lower memory requirements as execution times and memory usage were reduced by 20

    We report the study of dielectric properties of some silver ion conducting silver selenomolybdate mixed network former glasses in a wide frequency and temperature range. The experimental data have been analyzed in the framework of complex dielectric permittivity. The dielectric permittivity data have been well interpreted using the Cole-Cole function. The temperature dependence of relaxation time obtained from real part of dielectric permittivity data shows an Arrhenius behavior. The activation energy shows a decreasing trend with the increase of doping content. Values of stretched exponential parameter are observed to be independent of temperature and composition.

    [spa] Los coleópteros son en la actualidad el grupo biológico con mayor biodiversidad de la Tierra. Se conocen coleópteros fósiles desde el Pérmico, pero conservados en ámbar solo desde el Cretácico inferior. Este tipo de fosilización, en contraste con otros, permite realizar estudios anatómicos y evolutivos muy detallados. Son pocas las áreas del mundo donde existen yacimientos de ámbar mesozoico con abundantes bioinclusiones. Entre ellas, los yacimientos de España (Albiense) y Francia (Albi...

  8. Dielectric dispersion in pure and doped lithium rubidium sulphate

    Science.gov (United States)

    Kassem, M. E.; El-Muraikhi, M.; Al-Houty, L.; Mohamed, A. A.

    The frequency (102 - 105 Hz) dependence of the dielectric properties of lithium rubidium sulphate (LRS) are reported in the vicinity of the transition temperature Tc = 477 K. The a.c. conductivity σ(ω) shows a strong temperature dependence and weak frequency response. The dielectric constant in this region shows a strong frequency dispersion. A Cole-Cole diagram was used to determine the distribution parameter and the molecular relaxation time. The effect of doping with Dy+3, Sm+3 and V+3, was also studied. It was found that doping gives rise to localized states which produce a disorder in the structure of LiRbSO4.

    The dielectric parameters and relaxation properties of azo dye (DR1) doped E7 and pure E7 liquid crystal (LC) have been investigated in a wide frequency range of 10 k-10 MHz through the dielectric spectroscopy method at room temperature. Dielectric anisotropy (Δε) property of the LC changes from the positive type to negative type and dielectric anisotropy values decrease with doping of DR1. The relaxation frequency f r of E7 and E7/DR1 LC was calculated by means of Cole-Cole plots. Influence of bias voltage on the dielectric parameters has also been investigated

  15. Topics in elementary particle physics

    Science.gov (United States)

    Jin, Xiang

    The author of this thesis discusses two topics in elementary particle physics: n-ary algebras and their applications to M-theory (Part I), and functional evolution and Renormalization Group flows (Part II). In part I, Lie algebra is extended to four different n-ary algebraic structure: generalized Lie algebra, Filippov algebra, Nambu algebra and Nambu-Poisson tensor; though there are still many other n-ary algebras. A natural property of Generalized Lie algebras — the Bremner identity, is studied, and proved with a totally different method from its original version. We extend Bremner identity to n-bracket cases, where n is an arbitrary odd integer. Filippov algebras do not focus on associativity, and are defined by the Fundamental identity. We add associativity to Filippov algebras, and give examples of how to construct Filippov algebras from su(2), bosonic oscillator, Virasoro algebra. We try to include fermionic charges into the ternary Virasoro-Witt algebra, but the attempt fails because fermionic charges keep generating new charges that make the algebra not closed. We also study the Bremner identity restriction on Nambu algebras and Nambu-Poisson tensors. So far, the only example 3-algebra being used in physics is the BLG model with 3-algebra A4, describing two M2-branes interactions. Its extension with Nambu algebra, BLG-NB model, is believed to describe infinite M2-branes condensation. Also, there is another propose for M2-brane interactions, the ABJM model, which is constructed by ordinary Lie algebra. We compare the symmetry properties between them, and discuss the possible approaches to include these three models into a grand unification theory. In Part II, we give an approximate solution for Schroeder's equations, based on series and conjugation methods. We use the logistic map as an example, and demonstrate that this approximate solution converges to known analytical solutions around the fixed point, around which the approximate solution is constructed

    The aim of the present paper is to study the effect of argon ion implantation on electrical and dielectric properties of polycarbonate. Specimens were implanted with 130 keV Ar{sup +} ions in the fluence ranging from 1×10{sup 14} to 1×10{sup 16} ions cm{sup −2}. The beam current used was ∼0.40 µA cm{sup −2}. The electrical conduction behaviour of virgin and Ar{sup +} implanted polycarbonate specimens have been studied through current-voltage (I-V characteristic) measurements. It has been observed that after implantation conductivity increases with increasing ion fluence. The dielectric spectroscopy of these specimens has been done in the frequency range of 100 kHz-100 MHz. Relaxation processes were studied by Cole-Cole plot of complex permittivity (real part of complex permittivity, ε′ vs. imaginary part of complex permittivity, ε″). The Cole-Cole plots have also been used to determine static dielectric constant (ε{sub s}), optical dielectric constant (ε{sub ∞}), spreading factor (α), average relaxation time (τ{sub 0}) and molecular relaxation time (τ). The dielectric behaviour has been found to be significantly affected due to Ar{sup +} implantation. The possible correlation between this behaviour and the changes induced by the implantation has been discussed.

    Fractional calculus is a mathematical approach dealing with derivatives and integrals of arbitrary and complex orders. Therefore, it adds a new dimension to understand and describe basic nature and behavior of complex systems in an improved way. Here we use the fractional calculus for modeling electrical properties of biological systems. We derived a new class of generalized models for electrical impedance and applied them to human skin by experimental data fitting. The primary model introduces new generalizations of: 1) Weyl fractional derivative operator, 2) Cole equation, and 3) Constant Phase Element (CPE). These generalizations were described by the novel equation which presented parameter [Formula: see text] related to remnant memory and corrected four essential parameters [Formula: see text] We further generalized single generalized element by introducing specific partial sum of Maclaurin series determined by parameters [Formula: see text] We defined individual primary model elements and their serial combination models by the appropriate equations and electrical schemes. Cole equation is a special case of our generalized class of models for[Formula: see text] Previous bioimpedance data analyses of living systems using basic Cole and serial Cole models show significant imprecisions. Our new class of models considerably improves the quality of fitting, evaluated by mean square errors, for bioimpedance data obtained from human skin. Our models with new parameters presented in specific partial sum of Maclaurin series also extend representation, understanding and description of complex systems electrical properties in terms of remnant memory effects.

    High quality n-(CdMgTe:I/n-CdTe:I)/(p-CdTe:N/p-ZnCdTe:N/p-ZnTe:N)/p-GaAs heterojunction diodes have been fabricated by molecular beam epitaxial growth. The illumination effect on the complex impedance and conductivity of heterostructure diode was investigated. The illumination intensities were taken up to the 200 mW/cm2 with frequency range of 42 Hz to 1 MHz. The observed real and imaginary parts of the complex impedance were strongly dependent on the illumination frequency. The inverse relation was observed between the illumination intensity and the complex impedance. The relaxation mechanism of the diode was analyzed by the Cole-Cole plots. The radius of the Cole-Cole curve decreases with increasing illumination intensity. This suggests a mechanism of illumination dependent on the relaxation process. It is also found that the conductivity increases linearly with increasing the illumination intensity. We can conclude that the new design heterostructure diode in our work is a good candidate in photodetector and optoelectronic applications.

    In this study, the dielectric properties of metal-oxide-metal capacitors based on Tantalum Titanium Oxide (TiTaO) thin films deposited by reactive magnetron sputtering on aluminum bottom electrode are investigated. The structure of the films was characterized by Atomic Force Microscopy, X-ray diffraction and X-ray photoelectron spectroscopy. The dielectric properties of TiTaO thin films were studied by complex impedance spectroscopy over a wide frequency range (10{sup -2} - to 10{sup 5} Hz) and temperatures in -50 °C to 325 °C range. The contributions of different phases, phases’ boundaries and conductivity effect were highlighted by ColeCole diagram (ε” versus ε’). Two relaxation processes have been identified in the electric modulus plot. A first relaxation process appears at low temperature with activation energy of 0.37 eV and it is related to the motion of Ti{sup 4+} (Skanavi’s model). A second relaxation process at high temperature is related to Maxwell-Wagner-Sillars relaxation with activation energy of 0.41 eV. - Highlights: • Titanium Tantalum Oxide thin films are grown on Aluminum substrate. • The existence of phases was confirmed by X-ray photoelectron spectroscopy. • Conductivity effect appears in Cole-Cole plot. • At low temperatures, a relaxation phenomenon obeys to Skanavi’s model. • Maxwell-Wagner-Sillars polarization is processed at high temperatures.

  9. Spectral inversion of frequency-domain IP data obtained in Haenam, South Korea

    Spectral induced polarization (SIP) method using a range of source frequencies have been performed for not only exploring minerals resources, but also engineering or environmental application. SIP interpretation first makes inversion of individual frequency data to obtain complex resistivity structures, which will further analyzed employing Cole-Cole model to explain the frequency-dependent characteristics. However, due to the difficulty in fitting Cole-Cole model, there is a movement to interpret complex resistivity structure inverted only from a single frequency data: that is so-called "complex resistivity survey". Further, simultaneous inversion of multi-frequency SIP data, rather than making a single frequency SIP data, has been studied to improve ambiguity and artefacts of independent single frequency inversion in obtaining a complex resistivity structure, even though the dispersion characteristics of complex resistivity with respect to source frequency. Employing the simultaneous inversion method, this study makes inversion of field SIP data obtained over epithermal mineralized area, Haenam, in the southernmost tip of South Korea. The area has a polarizable structure because of extensive hydrothermal alteration, gold-silver deposits. After the inversion, we compare between inversion results considering multi-frequency data and single frequency data set to evaluate the performance of simultaneous inversion of multi-frequency SIP data.

    Full text: A single phase new perovskite based titanio-manganite (La 0.5-x Pr x Ba 0.5 )(Mn 0.5 Ti 0.5 )O 3 has been successfully prepared by ceramic C. The concentration of solid-state technique at sintering temperature of 1300 Pr (Praseodymium), x, in molar proportion in A site has been varied as x = 0.0, 0.2 and 0.02. Analysis has been carried out to determine the electrical properties of the synthesized material at frequency of 1 MHz and at temperature range between 25 to 200 degree Celsius. It is found that Pr addition promoted liquid sintering diffusion, porosity and agglomeration formation at 1300 degree Celsius. Dual relaxation is observed in unsubstituted Pr sample x = 0 and high Pr substituted sample x=0.2. This phenomenon was a combinational contribution from a quasi dc (QDC) low frequency dispersion and two cole-cole relaxational response. While low concentrated Pr substituted sampled x=0.02 shows a combinational contribution from a quasi dc (QDC) low frequency dispersion and single cole-cole relaxational response at room temperature. Pr substitution at x=0 and x=0.2 showed high dielectric values compared to low substituted sample x = 0.02. Variation of dielectric loss tangent (tan ) are observed for all samples at temperature ranged studied. (author)

  20. Impact of Pitot tube calibration on the uncertainty of water flow rate measurement

    Science.gov (United States)

    de Oliveira Buscarini, Icaro; Costa Barsaglini, Andre; Saiz Jabardo, Paulo Jose; Massami Taira, Nilson; Nader, Gilder

    Water utility companies often use Cole type Pitot tubes to map velocity profiles and thus measure flow rate. Frequent monitoring and measurement of flow rate is an important step in identifying leaks and other types of losses. In Brazil losses as high as 42% are common and in some places even higher values are found. When using Cole type Pitot tubes to measure the flow rate, the uncertainty of the calibration coefficient (Cd) is a major component of the overall flow rate measurement uncertainty. A common practice is to employ the usual value Cd = 0.869, in use since Cole proposed his Pitot tube in 1896. Analysis of 414 calibrations of Cole type Pitot tubes show that Cd varies considerably and values as high 0.020 for the expanded uncertainty are common. Combined with other uncertainty sources, the overall velocity measurement uncertainty is 0.02, increasing flowrate measurement uncertainty by 1.5% which, for the Sao Paulo metropolitan area (Brazil) corresponds to 3.5 × 107 m3/year.
