  1. 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.

    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.

  3. 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.

    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.

  8. Comparison of Cole-Cole and Constant Phase Angle modeling in time-domain induced polarization

    The Cole-Cole model and the constant phase angle (CPA) model are two prevailing phenomenological descriptions of the induced polarization (IP), used for both frequency domain (FD) and time domain (TD) modeling. The former one is a 4-parameter description, while the latest one involves only two......, forward modeling of quadrupolar sequences on 1D and 2D heterogeneous CPA models shows that the CPA decays differ among each other only by a multiplication factor.

    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.

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

    International Nuclear Information System (INIS)

    Yang, Yuxiang; Ni, Wenwen; Sun, Qiang; Wen, He; Teng, Zhaosheng

    2013-01-01

    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.

    1979-01-01

    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.

    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...

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

    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

    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.

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

    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.

    Ce cinquième volume de la correspondance d’Henri Poincaré rassemble l’ensemble des lettres envoyées par le mathématicien à sa famille durant ses années de formation à l’École polytechnique puis à l’École des mines de Paris. De 1873 à 1878, Poincaré écrit plus de 300 lettres à sa mère, à sa sœur et à son père. Une part importante de cette correspondance concerne ses études pour devenir ingénieur. Poincaré évoque ainsi les différents événements – importants ou anodins – qui ponctuent son parcours de formation dans les deux écoles: les cours et les examens, les voyages d’études en France et à l’étranger, les relations avec les professeurs, les rituels étudiants, la naissance de ses ambitions mathématiques.

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.

    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 an...

    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

    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.

  19. 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.

    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.

    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.

    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.

    Full Text Available This paper presents the preliminary results of a coupled modelling effort to study the fate of tailings (radioactive waste-by product downstream of the Coles Hill uranium deposit located in Virginia, USA. 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.

L’architecte obtint que la commande des vitraux soit adressée à Émile Hirsch, un peintre verrier parisien avec lequel il avait collaboré régulièrement sur d’autres chantiers. 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.

Cette étude a pour objectif de mieux comprendre les procédures développées par des élèves de 8 à 11 ans alors qu’ils évoluent de l'étape morphémique vers l'étape orthographique d'acquisition de l'orthographe grammaticale. Nous nous concentrons sur une compétence particulièrement attendue en fin d'école primaire : la réussite de l'accord sujet-verbe. 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.

    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

    In this letter, we investigate the characteristics of the dielectric properties of urea and ions such as potassium and sodium, which are the principal molecules studied during dialysis treatment. The method involves measuring the electrical properties of varying concentrations of the constituent...... solutions over a broad frequency range and estimating the associated Cole–Cole parameters. We utilized concentrations above those expected in vivo to achieve a more accurate characterization. In these studies, we found that the conductivity was essentially constant with respect to urea concentration but had...... a strong, nearly linear correlation with potassium. In addition, the alpha factor had a distinct, monotonically varying relationship for both urea and potassium with significantly different initial slopes. Utilizing these two curves, simple inversion algorithms are possible to compute the solute...

    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.

    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.

  1. Monomer-dimer control of the ColE1 P(cer) promoter.

    Science.gov (United States)

    Chatwin, H M; Summers, D K

    2001-11-01

    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.

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

    International Nuclear Information System (INIS)

    Seoane, F; Lindecrantz, Kaj; Ward, L C; Lingwood, B E

    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.

    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.

    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.

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.

    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...

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

    2001-12-01

    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.

    , 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 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.

    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.

    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.

  15. 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.

    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.

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

    International Nuclear Information System (INIS)

    Fitzgerald, A.J.; Thomas, B.J.; Cornish, B.H.; Michael, G.J.

    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

    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.

  13. 3-D time-domain induced polarization tomography: a new approach based on a source current density formulation

    Science.gov (United States)

    Soueid Ahmed, A.; Revil, A.

    2018-04-01

    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

    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.

Nessa perspectiva, a atividade experimental torna-se um importante instrumento de ensino a ser explorado no estudo da Física, que também pode ser vivenciado pelos alunos por meio do livro didático (LD. Nesta pesquisa, realiza-se uma análise comparativa das atividades experimentais nas coleções de Física coincidentes nas edições de 2012 e 2015 do Programa Nacional do Livro Didático (PNLD. Para isso, aplica-se a classificação proposta por Barros (2009, fundamentada em competências e habilidades dos Parâmetros Curriculares Nacionais para o Ensino Médio (PCNEM (BRASIL, 1999 e nos temas estruturadores de suas orientações educacionais complementares (PCN+ (BRASIL, 2002. Os resultados mostram uma distribuição não uniforme dos experimentos nos temas da Física, em que ainda prevalecem os arranjos relacionados aos movimentos dos corpos. Para as categorias e dimensões de análise, verifica-se que os autores procuram evidenciar as competências e habilidades do PCNEM, entretanto os aspectos históricos sociais continuam pouco contemplados nas duas edições do Programa. Por fim, espera-se que as informações apresentadas nesse trabalho possam contribuir para a prática docente, com foco nas atividades experimentais dos livros didáticos de Física.

    2012-01-01

    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 Existe uma extensa variedade genética no urucum que são conhecidas por denominações como "focinho de rato", "cabeça de moleque", "peruana", "bico de pato", "amarela", "piave" entre outras. Todas são caracterizadas por propriedades como porte da planta, período de produção, forma e cores das cachopas, deiscência, etc. A última década tem sido marcada por um melhoramento genético, buscando maior produtividade e, principalmente, maior teor de pigmentos. O Instituto Agronômico (IAC comporta no Polo Regional Centro Norte, (Pindorama, SP, uma coleção de plantas de urucum, com mais de 25 acessos, que em trabalhos anteriores foram avaliadas quanto às suas características agronômicas. Contudo, os teores de bixina e lipídeos, que também são características importantes das sementes de urucum, pois afetam diretamente o rendimento industrial, não foram estudados. Este estudo teve como objetivo a validação de uma metodologia analítica de determinação de bixina e a caracterização da coleção do IAC quanto aos teores de bixina e lipídios. Os resultados indicaram que no método proposto houve linearidade na faixa de trabalho utilizada para a análise de sementes de urucum. Os limites de detecção e quantificação foram de 0,31 e 0,63 g de carotenóides totais expressos como bixina por 100 g de semente, respectivamente. O método foi preciso mas sensível a alterações na massa de amostra, tempo de extração e no coeficiente de absorção (. As árvores existentes na coleção possuem altos teores de bixina na semente, variando (em base seca de 3,12 ± 0,06% a 6,26 ± 0,06%. Os teores de lipídios variaram de 1,97 ± 0% a 3,98 ± 0,09%.

    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.

Sa seconde particularité est de traiter de thématiques générales à côté de contenus classiques liés aux enjeux des métiers d'ingénieur. Sa troisième caractéristique est de s'appuyer sur une implication de l'équipe SHS dans les activités professionnalisantes, tout en les séparant des enseignements disciplinaires. Enfin, l'inscription des SHS à l'ECL s'effectue plus par l'enseignement que par la recherche, chaque membre de l'équipe étant rattaché à un laboratoire extérieur différent.

  11. Frequency and diversity of small cryptic plasmids in the genus Rahnella

    Directory of Open Access Journals (Sweden)

    Summers David K

    2010-02-01

    Full Text Available Abstract Background Rahnella is a widely distributed genus belonging to the Enterobacteriaceae and frequently present on vegetables. Although Rahnella has interesting agro-economical and industrial properties and several strains possess antibiotic resistances and toxin genes which might spread within microbial communities, little is known about plasmids of this genus. Thus, we isolated a number of Rahnella strains and investigated their complements of small plasmids. Results In total 53 strains were investigated and 11 plasmids observed. Seven belonged to the ColE1 family; one was ColE2-like and three shared homology to rolling circle plasmids. One of them belonged to the pC194/pUB110 family and two showed similarity to poorly characterised plasmid groups. The G+C content of two rolling circle plasmids deviated considerably from that of Rahnella, indicating that their usual hosts might belong to other genera. Most ColE1-like plasmids formed a subgroup within the ColE1 family that seems to be fairly specific for Rahnella. Intriguingly, the multimer resolution sites of all ColE1-like plasmids had the same orientation with respect to the origin of replication. This arrangement might be necessary to prevent inappropriate synthesis of a small regulatory RNA that regulates cell division. Although the ColE1-like plasmids did not possess any mobilisation system, they shared large parts with high sequence identity in coding and non-coding regions. In addition, highly homologous regions of plasmids isolated from Rahnella and the chromosomes of Erwinia tasmaniensis and Photorhabdus luminescens could be identified. Conclusions For the genus Rahnella we observed plasmid-containing isolates at a frequency of 19%, which is in the average range for Enterobacteriaceae. These plasmids belonged to diffent groups with members of the ColE1-family most frequently found. Regions of striking sequence homology of plasmids and bacterial chromosomes highlight the

    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

Os desafios para as bibliotecas públicas são muitos, dentre estes, a escassez de recursos financeiros, trazendo dificuldades para um exercício eficaz de seu papel social perante a comunidade. Nesse sentido, o planejamento de ações em torno da disponibilização de informação se torna algo de fundamental importância. O presente artigo propõe uma reflexão sobre o desenvolvimento de coleções e os desafios presentes no gerenciamento das coleções em bibliotecas públicas. As coleções são geridas com vistas a propor uma ordem para se tentar domar o aglomerado de itens informacionais. Estes itens são analisados, organizados e sistematizados nos acervos com base em planejamento e critérios e diretrizes sólidas, com intuito de proporcionar um crescimento racional e equilibrado. Por meio da revisão de literatura, verificaram-se alguns desafios e perspectivas sobre a prática de formar e desenvolver coleções no âmbito das bibliotecas públicas na contemporaneidade, as quais atuam como disseminadoras do conhecimento, constituem um espaço voltado para as atividades de promoção de leitura, cultura, cidadania, inclusão social e lazer. Neste sentido, são expostas algumas ações fundamentais em prol da formação e expansão das coleções, que corresponda às reais necessidades de informação do público alvo.

    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.

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

    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.

    The induced polarization (IP) method has been widely used in geophysical exploration to identify the chargeable targets such as mineral deposits. The inversion of the IP data requires modeling the IP response of 3D dispersive conductive structures. We have developed an edge-based finite-element time-domain (FETD) modeling method to simulate the electromagnetic (EM) fields in 3D dispersive medium. We solve the vector Helmholtz equation for total electric field using the edge-based finite-element method with an unstructured tetrahedral mesh. We adopt the backward propagation Euler method, which is unconditionally stable, with semi-adaptive time stepping for the time domain discretization. We use the direct solver based on a sparse LU decomposition to solve the system of equations. We consider the Cole-Cole model in order to take into account the frequency-dependent conductivity dispersion. The Cole-Cole conductivity model in frequency domain is expanded using a truncated Padé series with adaptive selection of the center frequency of the series for early and late time. This approach can significantly increase the accuracy of FETD modeling.

    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.

    The efficacy of emerging microwave breast cancer detection and treatment techniques will depend, in part, on the dielectric properties of normal breast tissue. However, knowledge of these properties at microwave frequencies has been limited due to gaps and discrepancies in previously reported small-scale studies. To address these issues, we experimentally characterized the wideband microwave-frequency dielectric properties of a large number of normal breast tissue samples obtained from breast reduction surgeries at the University of Wisconsin and University of Calgary hospitals. The dielectric spectroscopy measurements were conducted from 0.5 to 20 GHz using a precision open-ended coaxial probe. The tissue composition within the probe's sensing region was quantified in terms of percentages of adipose, fibroconnective and glandular tissues. We fit a one-pole Cole-Cole model to the complex permittivity data set obtained for each sample and determined median Cole-Cole parameters for three groups of normal breast tissues, categorized by adipose tissue content (0-30%, 31-84% and 85-100%). Our analysis of the dielectric properties data for 354 tissue samples reveals that there is a large variation in the dielectric properties of normal breast tissue due to substantial tissue heterogeneity. We observed no statistically significant difference between the within-patient and between-patient variability in the dielectric properties.

    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.

    The dielectric parameters and ac electrical conductivity of Mg{sub 0.8}Zn{sub 0.2}Cr{sub x}Fe{sub 2−x}O{sub 4}; (0≤x≤0.025) nanoferrites synthesized citrate–nitrate auto-combustion method were studied using the complex impedance technique in the frequency and temperature ranges 4 Hz–5 MHz and 303–873 K respectively. Hopping of charge carriers plus interfacial polarization could interpret the behaviors of dielectric constant (ε′), dielectric loss tangent (tanδ) and ac electrical conductivity (σ{sub ac}) with frequency, temperatures and composition. The up-normal behavior observed in tanδ trend with temperatures confirms the presence of relaxation loss (dipoles losses). Correlated barrier hopping (CBH) of electron is the conduction mechanism of the investigated nanoferrites. Cole-Cole plots at different temperatures emphasize the main role of grain and grain boundaries in the properties of the investigated nanoferrites. Cr{sup 3+} substitution can control the dielectric parameters and ac electrical conductivity of Mg-Zn nanoferrites making it candidates for versatile applications. - Highlights: • The composition dependence of ε′, tanδ, and σ{sub ac} showed the same trend. • CBH model is the conduction mechanism of the investigated nanoferrite. • Cole-Cole plots confirmed the role of grain and grain boundaries in our nanoferrites.

    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.

    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)

  1. 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

  4. High temperature dielectric relaxation anomaly of Y3+ and Mn2+ doped barium strontium titanate ceramics

    Relaxation like dielectric anomaly is observed in Y 3+ and Mn 2+ doped barium strontium titanate ceramics when the temperature is over 450 K. Apart from the conventional dielectric relaxation analysis method with Debye or modified Debye equations, which is hard to give exact temperature dependence of the relaxation process, dielectric response in the form of complex impedance, assisted with Cole-Cole impedance model corrected equivalent circuits, is adopted to solve this problem and chase the polarization mechanism in this paper. Through this method, an excellent description to temperature dependence of the dielectric relaxation anomaly and its dominated factors are achieved. Further analysis reveals that the exponential decay of the Cole distribution parameter n with temperature is confirmed to be induced by the microscopic lattice distortion due to ions doping and the interaction between the defects. At last, a clear sight to polarization mechanism containing both the intrinsic dipolar polarization and extrinsic distributed oxygen vacancies hopping response under different temperature is obtained.

    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.

  1. Comparison of species ordinations resulting from alternative indices of interspecific association and different numbers of included species

    Energy Technology Data Exchange (ETDEWEB)

    Goff, F G

    1975-12-19

    Several measures of interspecific association are compared. Dispersion and covariance are limited in value because they respond to the commonness of the species compared. Correlation is not so limited but it responds to discrepancies in commonness among the species. The practical result of these relationships between commonness and association is that only the most common species can occupy peripheral positions in a species ordination. Rare species are relegated to positions near the center not on the basis of their phytosociological pattern but simply because of their rarity. Both Cole's index of association and the tetrachoric correlation overcome the problem imposed by the relationship between ordination position and species commonness and they both produce very similar results. The effect of differing numbers of species on the ordination configuration is examined using both Pearson's correlation and Cole's index. The basic pattern of the ordination is set with the first few species when Cole's index is used, however, since rare species are given more weight in the analysis with this index, the addition of several very rare species can change the configuration of the ordination.

  3. Ultra-broadband and planar sound diffuser with high uniformity of reflected intensity

    Schroeder diffusers, as a classical design of acoustic diffusers proposed over 40 years ago, play key roles in many practical scenarios ranging from architectural acoustics to noise control to particle manipulation. Despite the great success of conventional acoustic diffusers, it is still worth pursuing ideal acoustic diffusers that are essentially expected to produce perfect sound diffuse reflection within the unlimited bandwidth. Here, we propose a different mechanism for designing acoustic diffusers to overcome the basic limits in intensity uniformity and working bandwidth in the previous designs and demonstrate a practical implementation by acoustic metamaterials with dispersionless phase-steering capability. In stark contrast to the existing production of diffuse fields relying on random scattering of sound energy by using a specific mathematical number sequence of periodically distributed unit cells, we directly mold the reflected wavefront into the desired shape by precisely manipulating the local phases of individual subwavelength metastructures. We also benchmark our design via numerical simulation with a commercially available Schroeder diffuser, and the results verify that our proposed diffuser scatters incident acoustic energy into all directions more uniformly within an ultra-broad band regardless of the incident angle. Furthermore, our design enables further improvement of the working bandwidth just by simply downscaling each individual element. With ultra-broadband functionality and high uniformity of reflected intensity, our metamaterial-based production of the diffusive field opens a route to the design and application of acoustic diffusers and may have a significant impact on various fields such as architectural acoustics and medical ultrasound imaging/treatment.

    Full Text Available Este artigo apresenta uma nova performance da gestão documental, voltada para o desenvolvimento das coleções no âmbito da informação jurídica, estabelecendo critérios de qualidade para os processos de seleção, aquisição e avaliação das informações. Para esse propósito, é feita uma avaliação das várias dimensões que permeiam a gestão documental da informação jurídica como um todo. A rapidez com que a informação jurídica se inova torna a literatura (ainda que recente ultrapassada e obsoleta, ocasionando, assim, uma maior dificuldade das bibliotecas permanecerem com suas publicações sempre atualizadas. Por isso, é preciso que sejam elaborados mecanismos de controle e que seja efetuado um bom desenvolvimento dos serviços prestados pelas mesmas. Esses mecanismos são criados por meio da política de desenvolvimento de coleções, pois, quando bem fundamentada, assegura o bibliotecário na tomada de decisões, tanto em relação ao processo de seleção, aquisição e descarte do acervo, como na sustentação da qualidade na atualização da coleção. O processo de desenvolvimento da coleção é visto sob o viés da abordagem sistêmica das organizações.

    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....

  7. Energy consensus talks collapse over nuclear issues

    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)

    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.

    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.

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.

The goal of the project was to find ways to improve communication and reporting about general performance of the school as part of the school's accountability to its members. Starting from lessons of the balanced scorecard approach for non-profits, we describe the process of development of survey-based measures for the particular organization. The direction of the tool development and subsequent organizational changes were carried out in a participatory process between the school's staff, the parents, and the board.

    A small plasmid designated pCS36-4CPA with a size of 5217 base pairs and G-C content of 50.74% was isolated from Citrobacter sp. 36-4CPA. The origin of replication ( ori ) of the plasmid was identified as a region of about 800 bp in length with an identity of 67.1% to the ColE1 plasmid at the nucleotide level. The replication region contained typical elements of ColE1-like plasmids: RNA I and RNA II with their corresponding -10 and -35 boxes, a single-strand initiation site ( ssi ), and a lagging-strand termination site ( terH ). As seen in other ColE1-like plasmids, pCS36-4CPA carried mobilisation machinery that include mobABCD genes but it did not possess the rom gene. Analysis of the multimer resolution site ( mrs ) was performed and XerC and XerD binding sites were identified. Also, the 70-nt transcript Rcd of pCS36-4CPA was predicted and similarity of the transcript's secondary structure with those of the ColE1-family was shown. The cargo module of pCS36-4CPA contained three open reading frames (ORFs). Two of them (ORF5 and ORF6) showed no significant homology to any known gene sequences but contained putative THAP DNA-binding (DBD) and type II restriction endonuclease Eco O109I domains. The seventh open reading frame (ORF7) encodes YhdJ-like DNA modification methylase. The region highly homologous to pCS36-4CPA was found in the Salmonella phage SE2 genome.

    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

    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.

  2. Interspecific nest parasitism by chukar on greater sage-grouse

    Science.gov (United States)

    Fearon, Michelle L.; Coates, Peter S.

    2014-01-01

    Nest parasitism occurs when a female bird lays eggs in the nest of another and the host incubates the eggs and may provide some form of parental care for the offspring (Lyon and Eadie 1991). Precocial birds (e.g., Galliformes and Anseriformes) are typically facultative nest parasites of both their own and other species (Lyon and Eadie 1991). This behavior increases a female’s reproductive success when she parasitizes other nests while simultaneously raising her own offspring. Both interspecific and conspecific nest parasitism have been well documented in several families of the order Galliformes, particularly the Phasianidae (Lyon and Eadie 1991, Geffen and Yom-Tov 2001, Krakauer and Kimball 2009). The Chukar (Alectoris chukar) has been widely introduced as a game bird to western North America from Eurasia and is now well established within the Great Basin from northeastern California east to Utah and north to Idaho and Oregon (Christensen 1996). Over much of this range the Chukar occurs with other phasianids, including the native Greater Sage-Grouse (Centrocercus urophasianus), within sagebrush (Artemisia spp.) steppe (Christensen 1996, Schroeder et al. 1999, Connelly et al. 2000). Chukar typically exploit a broader range of habitats than do sage-grouse, but both species use the same species of sagebrush and other shrubs for nesting cover (Christensen 1996, Schroeder et al. 1999). Chukar are known to parasitize nests of other individuals of their own species (Geffen and Yom-Tov 2001), but we are unaware of reported evidence that Chukar may parasitize nests of sage-grouse. Here we describe a case of a Chukar parasitizing a sage-grouse nest in the sagebrush steppe of western Nevada.

  6. Experimental Monitoring of Cr(VI) Bio-reduction Using Electrochemical Geophysics

    2007-01-01

    Many Department of Energy (DOE) sites are contaminated with highly carcinogenic hexavalent chromium (Cr(VI)). In this research, we explore the feasibility of applying complex resistivity to the detection and monitoring of microbially-induced reduction of hexavalent chromium (Cr(VI)) to a less toxic form (Cr(III)). We hope to measure the change in ionic concentration that occurs during this reduction reaction. This form of reduction promises to be an attractive alternative to more expensive remedial treatment methods. The specific goal of this research is to define the minimum and maximum concentration of the chemical and biological compounds in contaminated samples for which the Cr(VI) - Cr(III) reduction processes could be detected via complex resistivity. There are three sets of experiments, each comprised of three sample columns. The first experiment compares three concentrations of Cr(VI) at the same bacterial cell concentration. The second experiment establishes background samples with, and without, Cr(VI) and bacterial cells. The third experiment examines the influence of three different bacterial cell counts on the same concentration of Cr(VI). A polarization relaxation mechanism was observed between 10 and 50 Hz. The polarization mechanism, unfortunately, was not unique to bio-chemically active samples. Spectral analysis of complex resistivity data, however, showed that the frequency where the phase minimum occurred was not constant for bio-chemically active samples throughout the experiment. A significant shifts in phase minima occurred between 10 to 20 Hz from the initiation to completion of Cr(VI) reduction. This phenomena was quantified using the Cole-Cole model and the Marquardt-Levenberg nonlinear least square minimization method. The data suggests that the relaxation time and the time constant of this relaxation are the Cole-Cole parameters most sensitive to changes in biologically-induced reduction of Cr(VI)

  7. Fast Simulation of Dynamic Ultrasound Images Using the GPU.

    2017-10-01

    Simulated ultrasound data is a valuable tool for development and validation of quantitative image analysis methods in echocardiography. Unfortunately, simulation time can become prohibitive for phantoms consisting of a large number of point scatterers. The COLE algorithm by Gao et al. is a fast convolution-based simulator that trades simulation accuracy for improved speed. We present highly efficient parallelized CPU and GPU implementations of the COLE algorithm with an emphasis on dynamic simulations involving moving point scatterers. We argue that it is crucial to minimize the amount of data transfers from the CPU to achieve good performance on the GPU. We achieve this by storing the complete trajectories of the dynamic point scatterers as spline curves in the GPU memory. This leads to good efficiency when simulating sequences consisting of a large number of frames, such as B-mode and tissue Doppler data for a full cardiac cycle. In addition, we propose a phase-based subsample delay technique that efficiently eliminates flickering artifacts seen in B-mode sequences when COLE is used without enough temporal oversampling. To assess the performance, we used a laptop computer and a desktop computer, each equipped with a multicore Intel CPU and an NVIDIA GPU. Running the simulator on a high-end TITAN X GPU, we observed two orders of magnitude speedup compared to the parallel CPU version, three orders of magnitude speedup compared to simulation times reported by Gao et al. in their paper on COLE, and a speedup of 27000 times compared to the multithreaded version of Field II, using numbers reported in a paper by Jensen. We hope that by releasing the simulator as an open-source project we will encourage its use and further development.

  8. Electrical Spectroscopy of Permo-Triassic Sandstone From the United Kingdom

    2003-12-01

    Electrical spectroscopy measurements in the range of mHz to kHz have been made on the dominantly red Permo-Triassic sandstone from the United Kingdom. Samples have been selected from borehole cores from all of the main outcrop areas of sandstone and represent a wide variety of lithologies. This sandstone is an important aquifer for several major cities including Manchester and Birmingham. The samples have been fully saturated with sodium chloride brines and a synthetic groundwater solution that is higher in calcium and magnesium ions than sodium and which closely matches the cation concentrations of the groundwater at Birmingham. Electrical measurements were made using a four-electrode arrangement of silver-silver chloride electrodes. Most of the electrical spectra show a clear, slightly asymmetric, electrical relaxation phenomenon with relaxation peaks in the range of 0.001 Hz to 20 Hz. These relaxation phenomena can be fitted very well by a generalised Cole-Cole model. The relaxation time from this model is found to correlate closely with the dominant pore-throat size from mercury injection. Normalising the chargeability, Cole-Cole m parameter, by the conductivity gives a polarisation magnitude which correlates well with the pore surface to volume ratio (SPOR) for sandstone samples with an even distribution of surface coating clays. The information obtained from the electrical spectra is very useful. The pore-throat size is important in controlling the permeability and in particular the flow of non-aqueous phase fluids. The pore surface area has links to the sorbtion properties of the rock, which are important in estimating contaminant transport.

    The ac-conductivity and dielectric response of new composites based on zinc-phosphate glass with composition 45 mol%ZnO–55 mol%P{sub 2}O{sub 5}, filled with metallic powder of nickel (ZP/Ni) were investigated by impedance spectroscopy in the frequency range from 100 Hz to 1 MHz at room temperature. A high percolating jump of seven times has been observed in the conductivity behavior from low volume fraction of filler to the higher fractions, indicating an insulator – semiconductor phase transition. The measured conductivity at higher filler volume fraction is about 10{sup −1} S/cm and is frequency independent, while, the obtained conductivity for low filler volume fraction is around 10{sup −8} S/cm and is frequency dependent. Moreover, the elaborated composites are characterized by high dielectric constants in the range of 10{sup 5} for conductive composites at low frequencies (100 Hz). In addition, the distribution of the relaxation processes was also evaluated. The Debye, Cole-Cole, Davidson–Cole and Havriliak–Negami models in electric modulus formalism were used to model the observed relaxation phenomena in ZP/Ni composites. The observed relaxation phenomena are fairly simulated by Davidson–Cole model, and an account of the interpretation of results is given. - Highlights: • Composites of ZnO-P{sub 2}O{sub 5}/metal were investigated by impedance spectroscopy. • Original ac-conductivity behavior was discovered in ZnO-P{sub 2}O{sub 5}/metal composites. • High dielectric constant is measured in ZnO-P{sub 2}O{sub 5}/metal composites. • Dielectric constant as filler function is well interpreted with percolation theory. • Observed relaxation processes are well described using electric modulus formalism.

  12. Measurement of the Clausius-Mossotti second virial coefficients of noable gases

    International Nuclear Information System (INIS)

    Woo, J.C.; Kromhout, R.A.

    1980-01-01

    The second virial coefficient of the Clausius-Mossotti function has been measured by means of consecutive expansions with a high resolution Fabry-Perot interferometer and a highly stable, single frequency He-Ne laser. The second virial coefficients are obtained for three gases, helium, neon and argon with values of -0.15, 2.5 and 0.2, respectively. The results obtained in this work agree closely with the dc measurements made by Cole and coworker. Both of these experimental results, however, show large inconsistencies with theoretical values. For helium in particular, a negative value is observed both in this work and Cole's, while the careful theoretical approaches call for a larger positive value. (author)

  13. Characterization of oxygen vacancies and their migration in Ba-doped Pb(Zr0.52Ti0.48)O3 ferroelectrics

    We investigate in detail the migration kinetics of oxygen vacancies (OVs) in Ba-doped Pb(Zr0.52Ti0.48)O3 (PZT) ferroelectrics by complex impedance spectroscopy. The temperature dependent dc-electrical conductivity σdc suggests that Ba doping into PZT can lower significantly the density of OVs, leading to the distinctly decreased σdc and slightly enhanced activation energy U for the migration of OVs, thus benefiting the polarization fatigue resistance. Furthermore, the polarization fluctuation induced by the relaxation of OVs is reduced by the Ba doping. The Cole-Cole fitting to the dielectric loss manifests strong correlation among OVs, and the migration of OVs appears to be a collective behavior.

    Dielectric properties of spinel ferrite samples Co{sub 1+x}Ti{sub x}Cr{sub 1.2-2x}Fe{sub 0.8}O{sub 4} (0<=x<=0.5) were investigated as a function of frequency at different temperatures using a complex impedance technique. Also Cole-Cole diagrams of both permittivity and electric modulus were investigated at different temperatures to have an insight into the electric nature of the studied solids. It has been found that the electric modulus M* is the dominating property clarifying the intrinsic picture of these polycrystalline ferrites. The low conductivity and loss factor values indicate that the studied compositions may be good candidates for practical applications.

  6. Impact of the displacement current on low-frequency electromagnetic fields computed using high-resolution anatomy models

    International Nuclear Information System (INIS)

    Barchanski, A; Gersem, H de; Gjonaj, E; Weiland, T

    2005-01-01

    We present a comparison of simulated low-frequency electromagnetic fields in the human body, calculated by means of the electro-quasistatic formulation. The geometrical data in these simulations were provided by an anatomically realistic, high-resolution human body model, while the dielectric properties of the various body tissues were modelled by the parametric Cole-Cole equation. The model was examined under two different excitation sources and various spatial resolutions in a frequency range from 10 Hz to 1 MHz. An analysis of the differences in the computed fields resulting from a neglect of the permittivity was carried out. On this basis, an estimation of the impact of the displacement current on the simulated low-frequency electromagnetic fields in the human body is obtained. (note)

    2012-11-01

    AC conductivity and dielectric properties of tungsten trioxide (WO3) in a pellet form were studied in the frequency range from 42 Hz to 5 MHz with a variation of temperature in the range from 303 K to 463 K. AC conductivity, σac(ω) was found to be a function of ωs where ω is the angular frequency and s is the frequency exponent. The values of s were found to be less than unity and decrease with increasing temperature, which supports the correlated barrier hopping mechanism (CBH) as the dominant mechanism for the conduction in WO3. The dielectric constant (ε‧) and dielectric loss (ε″) were measured. The Cole-Cole diagram determined complex impedance for different temperatures.

    In the present work Ag-starch nanocomposite films were fabricated via chemical reduction route. The formation of Ag nanoparticles was confirmed using transmission electron microscopy (TEM). Further the effect of varying concentration of Ag nanoparticles on the dielectric properties of starch has been studied. The frequency response of dielectric constant (ε‧), dielectric loss (ε″) and dissipation factor tan(δ) has been studied in the frequency range of 100 Hz to 1 MHz. Dielectric data was further analysed using Cole-Cole plots. The dielectric constant of starch was found to be 4.4 which decreased to 2.35 in Ag-starch nanocomposite film containing 0.50 wt% of Ag nanoparticles. Such nanocomposites with low dielectric constant have potential applications in microelectronic technologies.

    Full Text Available Litton Industries decided to establish one of its divisions in Northern Spain in 1965 called Litton-Cole. They chose Asturias to set up a factory intended to manufacture office furniture with a metallic component. The region had the potential to develop this kind of product due to its industrial base. It was easy to be provided with materials like steel, but above all a specialized workforce from Asturias’ Arms Industry. In the context of Spanish sixties José Antonio Menéndez Hevia was in charge of designing several banks and other public commercial establishments. Due to his connection with the Asturian banking sector, he had the opportunity to design office furniture set for Cole Steel. Cole Steel was the commercial name for the Asturian factory. Menéndez Hevia designed a very thorough set with almost twenty possible combinations that was commercialized under the name of Sintex. The series was successful on a national scale which was aimed at furnishing bank branch offices, but it was also exported to countries like Italy. Thousands of units were sold as part of one of the few Spanish design products manufactured in series at that time. The factory was closed in 1977, but in the general background of Spanish industrial design this series was forgotten, being part of our usual anonymous design history.

    Choi, Hyun-Min; Kim, Won-Jong; Lee, Jong-Yong; Hong, Jin-Woong; Kim, Tae-Wan

    2010-01-01

    Temperature-dependent dielectric properties were studied in a device with a structure of ITO/amorphous fluoropolymer (AF)/Al. The AF was thermally deposited at a deposition rate of 0.1 A/s to a thickness of 20 nm under a pressure of 5 x 10 -6 Torr. From the dielectric properties of the device, an equivalent circuit for and the equivalent complex impedance Z eq of the device were obtained. The interfacial resistance was found to be approximately 38 Ω. As the temperature was increased, the radius of the Cole-Cole plot and β also increased for a constant applied voltage. However, as the applied voltage was increased, those values decreased at a constant temperature. These behaviors are thought to be due to an orientational polarization effect of the molecules inside the AF layer.

    2017-05-01

    We report the study of dielectric properties of mixed network former glasses of composition 0.3Ag2O-0.7(xSeO2-(1-x)TeO2); x=0, 0.1, 0.3, 0.4, 0.5 and 0.6 in a wide frequency 10 Hz - 2 MHz and temperature range 223 K - 403 K. The experimental data have been analyzed in the framework of complex dielectric permittivity. The dielectric permittivity data have been analyzed using the Cole-Cole function. The inverse temperature dependence of relaxation time obtained from real part of dielectric permittivity data follows the Arrhenius relation. The activation energy shows mixed glass former effect with variation of mixed former ratio. A non-zero value of shape parameters is observed and it is almost independent of temperature and composition.

The improved value of coercivity is quite beneficial for the perpendicular recording media which is an emerging technology in the recording media.

  18. Modeling electrical dispersion phenomena in Earth materials

    Directory of Open Access Journals (Sweden)

    D. Patella

    2008-06-01

    Full Text Available It is illustrated that IP phenomena in rocks can be described using conductivity dispersion models deduced as solutions to a 2nd-order linear differential equation describing the motion of a charged particle immersed in an external electrical field. Five dispersion laws are discussed, namely: the non-resonant positive IP model, which leads to the classical Debye-type dispersion law and by extension to the Cole-Cole model, largely used in current practice; the non-resonant negative IP model, which allows negative chargeability values, known in metals at high frequencies, to be explained as an intrinsic physical property of earth materials in specific field cases; the resonant flat, positive or negative IP models, which can explain the presence of peak effects at specific frequencies superimposed on flat, positive or negative dispersion spectra.

  19. The contribution of soil adhesion to radiocaesium uptake by leafy vegetables

    International Nuclear Information System (INIS)

    Amaral, E.C.S.; Paretzke, H.G.; Campos, M.J.; Pires do Rio, M.A.; Franklin, M.

    1994-01-01

    The Goiania accident, Brazil, was used as an opportunity to quantify the contributions of different mechanisms, in particular mass loading, leading to caesium uptake by leafy vegetables in a semi-urban environment contaminated with 137 Cs. Soil splash contributions of 70-90% were quantified for lettuce and 50-60% for green cole. Soil mass loadings of 130 and 340 mg.g -1 were estimated for lettuce and 120 and 150 mg.g -1 for green cole. The results call attention to the potential significant contribution of the soil splash to radionuclide uptake by plants which have the edible plant parts near the soil surface (within 30-40 cm) and low root uptake factors. For radiological assessment purposes it could also be necessary to consider the contamination of crops by this mechanism. (orig.)

  1. Identification of the non-pertechnetate species in Hanford waste tanks, Tc(I) carbonyl complexes

    Immobilization of the high-level nuclear waste stored at the Hanford Reservation has been complicated by the presence of soluble, lower-valent technetium species. Previous work by Schroeder and Blanchard has shown that these species cannot be removed by ion-exchange and are difficult to oxidize. The Tc-K edge XANES spectra of the species in Tanks SY-101 and SY-103 were reported by Blanchard, but they could not be assigned to any known technetium complex. We report that the XANES spectra are most likely those of Tc(I) carbonyl species, especially fac-Tc(CO){sub 3}(gluconate){sup 2-}. This is further supported by EXAFS and {sup 99}Tc-NMR studies in nonradioactive simulants of these tank wastes.

    Full Text Available Cet article part de la prémisse selon laquelle le principal défi qui se pose à l'école publique brésilienne concerne la redéfinition de ses rapports avec les milieux populaires. Il s'agit en effet de passer d'un modèle asymétrique et paternaliste à un modèle égalitaire et équitable. Ce défi institutionnel a alimenté un agenda de recherches sur les rapports qui relie l'école au "monde de l'élève" dont fait partie sa famille et son voisinage. Cet article présente les données obtenues lors d'une enquête auprès de parents et de responsables d'élèves, habitant presque tous des favelas. La lecture des données recueillies nous a conduit à une réflexion sur la valeur que l'école assume auprès des segments populaires. Elle met en évidence un horizon de conflits au sein de l'espace scolaire. Afin de faire face à ce scénario sous l'angle de la gestion scolaire, nous avons emprunté à la sociologie du droit la notion de "responsivité" qui permet de penser la façon de transformer des expectatives de mobilité sociale et d'accès à la cité en une institutionnalité accrue, en davantage de démocratie.

    The aim of our study was to induce with radiation of atrazine resistant and tolerated mutants in Coles, Amsoy-71 and 1937 soybean varieties. Atrazine that is photosynthetic inhibitor is the most important herbicide of S-triazin group, and shows toxic effect on soybean plant. For the improvement of the atrazine resistant plants with mutation breeding, the seeds belonging to the three varieties were irradiated with 200 Gy of gamma radiation dose. The irradiated seeds were sown in the field and at the end of harvesting season, every pod at node situated on the main stem was picked up separately and M 2 generations were obtained. At the plants, which were obtained from M 2 generation, chlorophyll mutants were determined and atrazine selection was made. The percentage of chlorophyll mutants for Amsoy-71, Coles and 1937 soybean varieties were found as 1.07, 1.48 and 1.32, respectively. At the end of atrazine selection, the percentages of atrazine resistant plants for Amsoy-71, Coles and 1937 soybean varieties were 0.80, 0.60 and 0.53, respectively. The percentages of atrazine tolerated plants were 1.07, 1.18 and 1.05, respectively as well. In our research; the differences among the mutants replying to atrazine in various concentrations were examined by using RAPD procedure as the molecular marker techniques in comparison with polymorphism. In the study done by using 14 primers; according to the amplification results, the differences between atrazine resistant plants were shown

  12. FDTD modelling of induced polarization phenomena in transient electromagnetics

    Science.gov (United States)

    Commer, Michael; Petrov, Peter V.; Newman, Gregory A.

    2017-04-01

    The finite-difference time-domain scheme is augmented in order to treat the modelling of transient electromagnetic signals containing induced polarization effects from 3-D distributions of polarizable media. Compared to the non-dispersive problem, the discrete dispersive Maxwell system contains costly convolution operators. Key components to our solution for highly digitized model meshes are Debye decomposition and composite memory variables. We revert to the popular Cole-Cole model of dispersion to describe the frequency-dependent behaviour of electrical conductivity. Its inversely Laplace-transformed Debye decomposition results in a series of time convolutions between electric field and exponential decay functions, with the latter reflecting each Debye constituents' individual relaxation time. These function types in the discrete-time convolution allow for their substitution by memory variables, annihilating the otherwise prohibitive computing demands. Numerical examples demonstrate the efficiency and practicality of our algorithm.

    Potassium Chloride (KCl) doped poly(vinyl alcohol) (PVA)/sodium alginate (NaAlg) in 60:40 wt% polymer blend electrolytes were prepared by solution casting method. The complexation of KCl with host PVA/NaAlg blend is confirmed by FTIR and UV-Vis spectra. The XRD studies show that the crystallinity of the prepared blends increases with increase in doping. The dc conductivity increases with increase in dopant concentration. Temperature dependent dc conductivity shows an Arrhenius behavior. The dielectric properties show that both the dielectric constant and dielectric loss increases with increase in KCl doping concentration and decreases with frequency. The cole-cole plots show a decrease in bulk resistance, indicates the increase in ac conductivity, due to increase in charge carrier mobility. The doping of KCl enhances the mechanical properties of PVA/NaAlg, such as Young's modulus, tensile strength, stiffness.

    The variation of the relative permittivity epsilon'sub(r), the loss factor epsilon'' and a.c. conductivity σ with the frequency of an applied electromagnetic field over the range 0.5 to 50 MHz has been studied in the leaf and stem tissues of three tropical vegetables viz - amaranthus, bitter leaf and okra. This is with a view to investigate the molecular structure and dielectric heating characteristics of the leaves and stems in the different vegetables considered. The Cole-Cole plots of the data showed that in all cases, both the stems and leaves exhibited a spread of relaxation times, indicating heterogeneity of structure. In general, the a.c. conductivity and the dielectric energy loss factor also appear to be much larger in the vegetable stems than in the leaves, suggesting that energy dissipation in stems is greater than in the leaves.

    Hunger, Johannes; Stoppa, Alexander; Buchner, Richard; Hefter, Glenn

    2008-10-16

    Dielectric spectra have been measured at 25 degrees C for mixtures of the room temperature ionic liquid 1- N-butyl-3- N-methylimidazolium tetrafluoroborate (IL) with dichloromethane (DCM) over the entire composition range at frequencies 0.2 less than or approximately nu/GHz < or = 89. The spectra could be satisfactorily fitted by assuming only two relaxation modes: a Cole-Cole process at lower frequencies and a Debye process at higher frequencies. However, detailed analysis indicated that both spectral features contain additional modes, which could not be resolved due to overlaps. The spectra indicate that the IL appears to retain its chemical character to extraordinarily high levels of dilution ( x IL greater than or approximately 0.5) in DCM. At even higher dilutions ( x IL less than or approximately 0.3), the IL behaves as a conventional but strongly associated electrolyte.

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.

Studies the first official efforts for the people schooling with the contribution of the religious congregations. Their proposal was the cultural assimilation. Later, the French Third Republic encreases secular assimilation policy. Finally, from 1946, the Reunion Island remains one of the first French empire, and begins to be administrative department of France, and remoteness becomes European territory.

Les conférences de Sicard et de Garat, professeurs à l’École Normale, sont bien complémentaires et ont certainement été écrites avec la volonté de produire des textes de référence dont le contenu servirait à influencer l’enseignement. C’est une rupture avec l’enseignement mécanique qui ne compte que sur la mémoire et l’imitation, rupture qui se sert de l’analyse comme mot d’ordre. Nous étudierons trois catégories grammaticales, discutées par Sicard et Garat, et leur développement dans les manuels de grammaire au début du dix-neuvième siècle : « phrase incidente », « verbe auxiliaire », « ellipse ». On analysera l’influence de ces concepts syntaxiques sur les manuels scolaires pour l’enseignement du français langue étrangère. Si l’on veut comprendre la production textuelle à l’École Normale, il est important de ne pas oublier qu’il s’agissait de donner des « leçons sur la meilleure méthode de les enseigner [les = les langues], et ces méthodes [...] seront tracées par des hommes dont la réputation est faite dans l’Europe » (Séances 1800-1801 : 1, VII.

  14. Effect of La-substitution on the structure and dielectric properties of BaBi4Ti4O15 ceramics

    International Nuclear Information System (INIS)

    Chakrabarti, A.; Bera, J.

    2010-01-01

    Four-layer Aurivillius compound BaBi 4-x La x Ti 4 O 15 (x = 0.1-1.0) is synthesized by a modified chemical route. X-ray diffraction analysis confirms the formation of single-phase Aurivillius compound. The crystal structure of compound changes from orthorhombic to pseudo-tetragonal at x = 0.5. BaBi 4-x La x Ti 4 O 15 shows typical relaxor behaviour. With increasing La 3+ substitution, shift of T m towards lower temperature and increased relaxor behaviour is observed. The substitution also results in a marked improvement in the remnant polarization and coercive field. The Cole-Cole plots show the presence of two semicircular arcs, suggesting the existence of grain and grain-boundary effects. The dc-conductivity and activation energies for both grain and grain boundary are evaluated. The ceramics with x = 0.3 presents the lowest conductivity among all compositions.

    Rabbit blood was preserved at 277 K in Alsever's solution for 37 days, and its dielectric permittivity was monitored in a frequency range from 0.05 to 110 MHz throughout the period. The relaxation time and Cole-Cole parameter of the interfacial polarization process for erythrocytes remained nearly constant during the first 20 days and then started to increase and decrease, respectively. On the other hand, the relaxation strength and the cell volume fraction continued to decrease for 37 days, but the decrease rates of both changed discontinuously on about the 20th day. Microscope observation showed that approximately 90% of the erythrocytes were spinous echinocytes at the beginning of preservation and started to be transformed into microspherocytes around the 20th day. Therefore, dielectric spectroscopy is a sensitive tool to monitor the deterioration of preserved blood accompanied by morphological transition of erythrocytes through the temporal variation of their dielectric properties

    The impendance of np-LiCoO{sub 2}+xPVDF, as a cathode material candidate for lithium-ion battery (LIB), has been characterized using impedance spectroscopy for x = 0, 5, 10, 15 and 20 volume percentage (%v/v) and for frequencies in the 42 Hz to 5 MHz range. Both real and imaginary components of the impedance were found to be frequency dependent, and both tend to increase for increasing PVDF (polyvinyilidene fluoride) concentration, except that for 10% PVDF both real and imaginary components of impedance are smaller than for 5%. The mechanism for relaxation time for each addition of PVDF was analyzed using Cole-Cole plots. The analysis showed that the relaxation times of the nanostructured LiCoO{sub 2} with PVDF additive is relatively constant. Further, PVDF addition increases the bulk resistance and decreases the bulk capacitance of the nanostructured LiCoO{sub 2}.

    This study investigates the synergistic effects of graphene oxide (GO) on the woven carbon fiber (CF)-reinforced epoxy composites. The GO nanofiller was incorporated into the epoxy resin with variations in the content, and the CF/epoxy composites were manufactured using a vacuum-assisted resin transfer molding process and then cured at 70 and 120 °C. An analysis of the mechanical properties of the GO (0.2 wt.%)/CF/epoxy composites showed an improvement in the tensile strength, Young's modulus, toughness, flexural strength and flexural modulus by 34, 20, 83, 55 and 31%, respectively, when compared to the CF/epoxy composite. The dynamic mechanical analysis of the composites exhibited an enhancement of 56, 114 and 22% in the storage modulus, loss modulus and damping capacity (tan δ), respectively, at its glass transition temperature. The fiber-matrix interaction was studied using a Cole-Cole plot analysis.

    2017-01-01

    This book describes the design and realization of analog fractional-order circuits, which are suitable for on-chip implementation, capable of low-voltage operation and electronic adjustment of their characteristics. The authors provide a brief introduction to fractional-order calculus, followed by design issues for fractional-order circuits of various orders and types. The benefits of this approach are demonstrated with current-mode and voltage-mode filter designs. Electronically tunable emulators of fractional-order capacitors and inductors are presented, where the behavior of the corresponding chips fabricated using the AMS 0.35um CMOS process has been experimentally verified. Applications of fractional-order circuits are demonstrated, including a pre-processing stage suitable for the implementation of the Pan-Tompkins algorithm for detecting the QRS complexes of an electrocardiogram (ECG), a fully tunable implementation of the Cole-Cole model used for the modeling of biological tissues, and a simple, non-i...

    2003-01-01

    The complex dielectric constant of ethyl alcohol, methyl alcohol and 1- propanol and their mixtures with water of different concentration, (0 to 100% by weight) at the temperature of 303K has been evaluated, within the frequency range of (100KHz- 100 MHz). Moreover, the viscosity mu of each alcohol and its mixture with water have been measured at this temperature. The dielectric properties have been evaluated by Hartshorn and Ward apparatus. The purpose of this work is to study the influence of aliphatic group, size and shape on the extent of hydrogen bonding and also to obtain the thermodynamic data on hydrogen bond formation in the pure liquid state and its mixture. The width of the semicircle plot determines the distribution of average relaxation time. Dielectric relaxation time in pure alcohols and their water mixture has been calculated from the respected Cole-Cole plot and dielectric data. A single relaxation time of 117.16ps has been obtained for the molecules of pure methanol, whereas, the dielectric data of prophyl alcohol which indicates the viscosity water have been measured at the temperature 303 K. The dielectric properties in distribution of relaxation time, which is in good agreement with the Davidson-cole representation. The molecules in liquid mixture within frequency range, the mixture has more than one relaxation item, leading to the shortening of main relaxation time as compared with the pure alcohol and broadening of the complex permitivity spectra. The dependence of the dielectric relaxation on composition shows a remarkable behavior. Results are discussed in the light of H-bonded molecules. (author)

  11. Dielectric behavior of MgO:Li+ crystals

    International Nuclear Information System (INIS)

    Puma, M.; Lorincz, A.; Andrews, J.F.; Crawford, J.H Jr.

    1980-01-01

    Measurements of the dielectric constant in crystals of MgO doped with Li + ions have been carried out after quenching from anneals at 1300 0 C in static air. Prior to heat treatment the crystals showed no discernible dielectric loss but afterwards the loss tangent exceeded 0.4. For 10 min anneals the dielectric relaxation is very close to a Debye process and the temperature dependence of the maximum of the loss peak corresponds to an activation energy of 0.72 eV. When plotted in the form of a Cole-Cole arc the data indicate that deviation from a Debye relaxation amounts to a distribution of relaxation time no greater than that which can be accounted for with a distribution of activation energies only 0.007 eV. For longer heating times overlapping relaxation processes appear. The lack of broadening of the loss peak and the magnitude of the relaxation time yield clues as to possible loss mechanisms

  12. Effect of silver nanoparticles on the dielectric properties of holmium doped silica glass

    Rejikumar, P.R.; Jyothy, P.V.; Mathew, Siby; Thomas, Vinoy; Unnikrishnan, N.V.

    2010-01-01

    The effect of silver nanoparticle co-doping on the dielectric properties of holmium doped silica glasses was studied. Silver nanoparticles of size between 20 and 22 nm were produced by the sol-gel technique. One of the samples showed an icosahedral morphology of the nanocrystal formed, along with spherical morphology. It was found that the tuning of the dielectric constant values could be accomplished by co-doping. The sample, with 1 wt% of Ho, had low dielectric constant values within the range 100 Hz-3 MHz due to the formation of quasi-molecular structures of holmium. This effect was evaded to some extent with silver co-doping as a result of the interdispersion of holmium complexes. Also it was found that the co-doping produced a higher dielectric loss which was calculated from the tan δ-log f graph. The Cole-Cole parameters and the Jonscher power law parameters were also calculated and are presented.

  14. Cross-linking and relaxation of supercoiled DNA by psoralen and light

    International Nuclear Information System (INIS)

    Yoakum, G.H.; Cole, R.S.

    1978-01-01

    Photoreaction of 4,5',8-trimethylpsoralen with superhelical ColE1 and ColE1amp DNA was studied. Changes in mobilities in agarose gels, formation of interstrand cross-links, and DNA strand breaks were determined. Psoralen and light treatment removed negative superhelical turns, and extensive treatments failed to produce positive superhelical turns in covalently closed plasmid DNA. The rate of relaxation of superhelical turns by psoralen photobinding appeared to be directly proportional to the number of superhelical turns remaining. A unique reaction mechanism is presented to explain these results. By this interpretation the initial rate of psoralen photobinding to superhelical DNA was estimated to be 3 times that for linear DNA, and the ratio of cross-linking to monofunctional adducts appears to be dependent on the superhelical conformation of the DNA. The estimated ratio of psoralen molecules bound to DNA strand breaks was 1.7 . 10 4 :1, and 70% of this breakage is caused by the light alone. (Auth.)

    Rabbit blood was preserved at 277 K in Alsever's solution for 37 days, and its dielectric permittivity was monitored in a frequency range from 0.05 to 110 MHz throughout the period. The relaxation time and Cole-Cole parameter of the interfacial polarization process for erythrocytes remained nearly constant during the first 20 days and then started to increase and decrease, respectively. On the other hand, the relaxation strength and the cell volume fraction continued to decrease for 37 days, but the decrease rates of both changed discontinuously on about the 20th day. Microscope observation showed that approximately 90% of the erythrocytes were spinous echinocytes at the beginning of preservation and started to be transformed into microspherocytes around the 20th day. Therefore, dielectric spectroscopy is a sensitive tool to monitor the deterioration of preserved blood accompanied by morphological transition of erythrocytes through the temporal variation of their dielectric properties.

  16. The experimental set-valued index of refraction of dielectric and anelastic media

    Directory of Open Access Journals (Sweden)

    M. Caputo

    2000-06-01

    Full Text Available The dielectric parameter, in the generalised Debye form, of all studied substances (Cole and Cole, 1941 contains a rational power of the imaginary frequency which implies that the index of refraction is a multivalued function of the frequency; the same property, concerning the stress strain relation, also applies to anelastic media (Bagley and Torvik, 1983a,b. The multivalued index of refraction implies then that the free modes of dielectric and anelastic media are split into a number of modes which depend on the exponent of the imaginary frequency. In order to estimate if it is possible to observe this splitting, this note computes the parameters appearing in the generalised Debye form of the dielectric parameters of many substances and also the complex anelastic parameter of an anelastic medium. The analysis of the data indicates that, depending on the accuracy of the experimental data, with few exceptions, the splitting is observable.

  19. Modeling and simulation of equivalent circuits in description of biological systems - a fractional calculus approach

    Directory of Open Access Journals (Sweden)

    José Francisco Gómez Aguilar

    2012-07-01

    Full Text Available Using the fractional calculus approach, we present the Laplace analysis of an equivalent electrical circuit for a multilayered system, which includes distributed elements of the Cole model type. The Bode graphs are obtained from the numerical simulation of the corresponding transfer functions using arbitrary electrical parameters in order to illustrate the methodology. A numerical Laplace transform is used with respect to the simulation of the fractional differential equations. From the results shown in the analysis, we obtain the formula for the equivalent electrical circuit of a simple spectrum, such as that generated by a real sample of blood tissue, and the corresponding Nyquist diagrams. In addition to maintaining consistency in adjusted electrical parameters, the advantage of using fractional differential equations in the study of the impedance spectra is made clear in the analysis used to determine a compact formula for the equivalent electrical circuit, which includes the Cole model and a simple RC model as special cases.

  20. Optical modulation in nematic phase of halogen substituted hydrogen bonded liquid crystals

    Vijayakumar, V. N.; Madhu Mohan, M. L. N.

    2012-01-01

    A series of halogen-substituted hydrogen-bonded liquid crystalline complexes have been designed and synthesised. A successful attempt has been made to form complementary hydrogen bonding between the dodecyloxy benzoic acid (12BAO) and halogen-substituted benzoic acids and the physical properties exhibited by the individual complexes are studied. The complexes obtained are analysed by polarising optical microscope (POM), differential scanning calorimetry (DSC), Fourier transform infrared spectroscopy (FTIR) and dielectric studies. The formation of complementary hydrogen bond is confirmed through FTIR spectra. An interesting feature of this series is the observation of a field-induced transition (FiT) in nematic phase. Another interesting phenomenon is the observation of a new smectic X phase (worm-like texture) in all the synthesised complexes. Dielectric relaxation studies in the smectic C phase of these hydrogen bonded complexes along with the Arrhenius and the Cole-Cole plots are discussed. Optical tilt angle in smectic C phase and the corresponding fitted data analysis concur with the Mean field theory prediction.

    The impedance spectra of tellurium films with interdigital platinum electrodes were investigated in air at temperatures between 10 and 50 deg. C . Cole-Cole analysis made it possible to assess time constants, resistance, and capacitance of the film at characteristic frequencies and the dependence of these parameters on aging and temperature. Aging under normal conditions over 12 months led to a relative increase of only {approx} 5% in film impedance at the characteristic frequency. However, aging noticeably influences the electrical resistance of the film at high (> 500 kHz) frequencies, and capacitance diminished after 12 months by more than 50% throughout the spectrum. Scanning electron microscopy confirmed that the effect of aging is due to structural changes in the film. Temperature does not influence the capacitance of the film but uncommonly influences its resistance, which reaches a maximum at around 20 deg. C . This is ascribed to desorption of oxygen previously adsorbed from the environment.

    Ultra-wideband (UWB) electromagnetic pulses of nanosecond duration, or nanopulses, are of considerable interest to the communications industry and are being explored for various applications in biotechnology and medicine. The propagation of a nanopulse through biological matter has been computed using the finite difference-time domain (FDTD) method. The approach required the reparametrization of existing Cole-Cole model-based descriptions of dielectric properties of biological matter in terms of the Debye model without loss of accuracy. Several tissue types have been considered. Results show that the electromagnetic field inside biological tissue depends on incident pulse rise time and width. Rise time dominates pulse behaviour inside tissue as conductivity increases. It has also been found that the amount of energy deposited by 20 kV m{sup -1} nanopulses is insufficient to change the temperature of the exposed material for pulse repetition rates of 1 MHz or less, consistent with recent experimental results.

    2018-05-01

    Since achievement in electromagnetic (EM) technology dramatically promotes the critical requirement in developing advanced EM response materials, which are required to hold various advantageous features in light weight, small thickness, strong reflection loss and broadband absorption, the most important requirements, i.e. strong reflection loss and broadband absorption, are still highly pursued because of the intrinsic shortage in conventional EM absorbers. For addressing such critical problems, a unique three-dimensional nitrogen doped carbon monolith was demonstrated to understand the effects of the nitrogen doping on the dielectric and microwave absorption performance. The chemical components of the nitrogen doped carbon monoliths have been quantitatively determined for fully understanding the effects of nanoscale structures on the macroscopic composites. A modified Cole-Cole plot is plotted for guiding the chemical doping and material process, aiming to realizing the best matching conditions. The results have promised a universal route for achieving advanced materials with strong and broadband EM absorption.

    We present on-chip Brownian relaxation measurements on a logarithmic dilution series of 40 nm beads dispersed in water with bead concentrations between 16 mu g/ml and 4000 mu g/ml. The measurements are performed using a planar Hall effect bridge sensor at frequencies up to 1 MHz. No external fields...... are needed as the beads are magnetized by the field generated by the applied sensor bias current. We show that the Brownian relaxation frequency can be extracted from fitting the Cole-Cole model to measurements for bead concentrations of 64 mu g/ml or higher and that the measured dynamic magnetic response...... is proportional to the bead concentration. For bead concentrations higher than or equal to 500 mu g/ml, we extract a hydrodynamic diameter of 47(1) nm for the beads, which is close to the nominal bead size of 40 nm. Furthermore, we study the signal vs. bead concentration at a fixed frequency close to the Brownian...

    An original polythiophene derivative was characterized to develop the optoelectronic properties of sulfur-containing π-conjugated polymer. The optical properties of the polymer were investigated by UV-visible absorption spectroscopy and atomic force microscopy. Investigations of the electrical characteristics of polymer diodes are reported. We present current-voltage characteristics and impedance spectroscopy measurements performed on partially sulfur-containing thin films in sandwich structure ITO/sulfur-containing polymer/Al. The conduction mechanisms in these layers are identified to be a space-charge-limited current. The AC electrical transport of the sulfur-containing polymer is studied as a function of frequency (100 Hz-10 MHz) and temperature in impedance spectroscopy analyses. We interpreted Cole-Cole plots in terms of the equivalent circuit model as a single parallel resistance and a capacitance network in series with a relatively small resistance. The evolution of the electrical parameters deduced from fitting of the experimental data is discussed.

The dc electrical conductivity was estimated from the Cole-Cole plot and the values were found to be 2.19 × 10-6 Sm-1 at 353K and 1.46 × 10-6 Sm-1 at 373K respectively. Mechanical studies on the grown crystal revealed that the material belongs to soft materials category. Thermal conductivity and specific heat capacities were estimated by Hot Disk Thermal Constants Analyzer.

    2017-11-01

    In this work, silica/poly(o-anisidine) (POA) core-shell structured microspheres were synthesized by coating the silica core surface with POA with a help of a chemical grafting agent, N-[(3-trimethoxylsilyl)-propyl] aniline. The synthesized silica microspheres were then applied as a polymer/inorganic composite particle-based electrorheological (ER) fluid. The morphology of the silica/POA microspheres was examined by using both transmission electron microscopy and scanning electron microscopy, while their thermal properties and chemical structure were checked by thermogravimetric analysis and Fourier-transform infrared spectroscopy, respectively. The ER properties of the silica/POA particle-based ER fluid were examined by using a Couette-type rotational rheometer equipped with a high-voltage power supplier and analyzed by the Bingham model and modified Mason number. In order to obtain additional information about the electrical polarization properties, the dielectric spectra were measured by an LCR meter and fitted by using the Cole-Cole equation. Furthermore, suspension stability of the ER fluid was tested using Turbiscan.

    2014-01-01

    The paper presents an analytical model to estimate blood glucose level from measurements made non-invasively and in real time by an antenna strapped to a patient's wrist. Some promising success has been shown by the RIT ETA Lab research group that an antenna's resonant frequency can track, in real time, changes in glucose concentration. Based on an in-vitro study of blood samples of diabetic patients, the paper presents a modified Cole-Cole model that incorporates a factor to represent the change in glucose level. A calibration technique using the input impedance technique is discussed and the results show a good estimation as compared to the glucose meter readings. An alternate calibration methodology has been developed that is based on the shift in the antenna resonant frequency using an equivalent circuit model containing a shunt capacitor to represent the shift in resonant frequency with changing glucose levels. Work under progress is the optimization of the technique with a larger sample of patients.

  14. Dynamical structure of water in aqueous solutions of D-glucose and D-galactose by low-frequency Raman scattering

    Wang, Yan; Tominaga, Yasunori

    1994-02-01

    Low-frequency depolarized Raman spectra of aqueous solutions of D-glucose and D-galactose have been investigated in the frequency region from -250 cm-1 to 250 cm-1 at 30.0 °C as a function of concentration up to 0.04 molar ratio. The dynamical structure of water in aqueous solution is analyzed by using the reduced Raman spectrum χ`(ν¯), which corresponds to the imaginary part of the dynamical susceptibility. The reduced spectrum is fitted with the superposition of one Cole-Cole type relaxation mode and two damped harmonic oscillator modes by a nonlinear least-squares fitting. The effects of D-glucose and D-galactose on the dynamical structure of water in aqueous solution are similar. The relaxation time of hydrogen bond among water molecules becomes slower with increasing sugar concentration. The characteristic frequencies of stretching-like and bending-like vibrations among water molecules do not change in both D-glucose and D-galactose aqueous solutions.

    Full Text Available Objectiu: El present treball reflecteix l'anàlisi econòmica financera de les grans indústries elaboradores de vi a Catalunya en el període 2008-2012. S'ha considerat la indústria  vinícola per ser un sector estratègic dintre de l'agroalimentació catalana, considerada  primer clúster agroalimentari d'Europa segons dades de l'observatori de clústers de l'Stockholm School of Economics. L'estudi posiciona aquestes indústries dintre del sector agroalimentari català i espanyol i presenta els principals indicadors econòmics i financers per tal de diagnosticar la salut d'aquestes empreses en el període 2008-2012 mitjançant una anàlisi a curt i llarg termini, una anàlisi de resultats i una anàlisi dels canvis patrimonials i dels fluxos d'efectiu de les empreses vinícoles. Disseny/metodologia/enfocament: Les dades utilitzades provenen dels estats comptables de les indústries vinícoles en el període 2008-2012, en concret, es recull una mostra d'empreses catalanes que elaboren vi amb uns ingressos d'explotació mínims de 5.700.000 € i uns actius mínims de 2.850.000 €, que presenten comptes anuals normals seguint el que disposa el Pla General Comptable en aquest període, i que majoritàriament són grans empreses sobre les que es porta a terme l'anàlisi econòmic financer mitjançant l'estadística descriptiva oportuna arribant a uns resultats i conclusions. Resultats: L'estudi permet assenyalar que les empreses vinícoles en aquest període gaudeixen d'una bona salut econòmica i financera, amb un reduït nombre d'empreses que concentren gran part de les vendes. Tot i que les vendes han augmentat, s'experimenta una reducció dels resultats econòmics per l'augment de les despeses d'explotació en aquest període. Per tant, no gaudeixen d'una gestió eficient de les despeses. Limitacions: Seria convenient estendre la mostra a petites empreses vinícoles i arribar fins a dades actuals per confirmar els canvis de tendència en l

    Natarajan Balasubramaniam

    2004-01-01

    Full Text Available This paper addresses signal compactness issues in MC-CDMA employing carrier interferometry codes using the measure of crest factor (CF. Carrier interferometry codes, applied to N -carrier MC-CDMA systems, enable 2N users to simultaneously share the system bandwidth with minimal degradation in performance (relative to the N -orthogonal-user case. First, for a fully loaded ( K=N and K=2N users MC-CDMA system with practical values of N , it is shown that the CF in downlink transmission demonstrates desirable properties of low mean and low variance. The downlink CF degrades when the number of users in the system decreases. Next, the high CF observed in the uplink is characterized and the poor CF in a partially loaded downlink as well as uplink is effectively combated using Schroeder's analytical CF reduction techniques.

    2008-01-01

    For some time now, statistical analysis has been a valuable tool in analyzing room transfer functions (RTFs). This work examines existing statistical time-frequency models and techniques for RTF analysis (e.g., Schroeder's stochastic model and the standard deviation over frequency bands for the RTF...... magnitude and phase). RTF fractional octave smoothing, as with 1-slash 3 octave analysis, may lead to RTF simplifications that can be useful for several audio applications, like room compensation, room modeling, auralisation purposes. The aim of this work is to identify the relationship of optimal response...... and the corresponding ratio of the direct and reverberant signal. In addition, this work examines the statistical quantities for speech and audio signals prior to their reproduction within rooms and when recorded in rooms. Histograms and other statistical distributions are used to compare RTF minima of typical...

  12. Adaptationism fails to resolve Fermi's paradox

    Directory of Open Access Journals (Sweden)

    Ćirković Milan M.

    2005-01-01

    Full Text Available One of the most interesting problems in the nascent discipline of astrobiology is more than half-century old Fermi's paradox: why, considering extraordinary young age of Earth and the Solar System in the Galactic context, don't we perceive much older intelligent communities or signposts of their activity? In spite of a vigorous research activity in recent years, especially bolstered by successes of astrobiology in finding extrasolar planets and extremophiles, this problem (also known as the "Great Silence" or "astrosociological" paradox remains as open as ever. In a previous paper, we have discussed a particular evolutionary solution suggested by Karl Schroeder based on the currently dominant evolutionary doctrine of adaptationism. Here, we extend that discussion with emphasis on the problems such a solution is bound to face, and conclude that it is ultimately quite unlikely. .

    Full Text Available Com objetivo de comparar a prevalência de obesidade infantil segundo três critérios antropométricos, foi realizado estudo transversal em oito escolas públicas estaduais na cidade de São Paulo, com crianças entre 6 e 11 anos de idade. Com base nas variáveis peso e altura, calculou-se o escore Z de P/E e o IMC. As prevalências de sobrepeso para o sexo masculino pelos critérios de Cole, Must e OMS foram de 10,92%, 10,29% e 11,94%, respectivamente, e para obesidade 8,17%, 13,67% e 10,29%. Para o sexo feminino, as prevalências de sobrepeso pelos critérios de Cole, Must e OMS foram de 13,51%, 13,83% e 13,67%, respectivamente, e para obesidade 8,25%, 16,50% e 11,73%. As variações nas estimativas de obesidade, se considerarmos os diferentes critérios, ressalta a necessidade de estudos populacionais e clínicos que orientem critério único, que além de identificar os indivíduos com maior probabilidade de excesso de gordura corporal, correlacione isto ao risco de adoecer e morrer, como ocorre com os pontos de corte 25 e 30 do IMC em adultos.To compare the prevalence of child obesity according to three criteria, a cross-sectional study was performed with 6-to-11-year-old children in eight elementary public schools in the city of São Paulo. Z scores for weight-for-height (W/H and body mass index (BMI were calculated from the weight and height variables. Prevalence rates for overweight in males, according to Must, Cole, and WHO criteria, were 10.92%, 10.29%, and 11.94%, respectively, and for obesity 8.17%, 13.67%, and 10.29%. For females, prevalence rates for overweight according to Must, Cole, and WHO criteria were 13.51%, 13.83%, and 13.67%, respectively, and for obesity 8.25%, 16.50%, and 11.73%. The study analyzes the variations in obesity estimates based on different criteria, highlighting the need for clinical and population studies to support the development of a single criterion.
