    Full Text Available Estudio de carácter histórico social que tiene como objetivo describir la memoria del servicio de enfermaria del Hospital Universitário de Santa Maria, en la Universidade Federal de Santa Maria – RS, durante el periodo de 1459 al 2000. Las fuentes primarias fueron documentos escritos y declaraciones orales de enfermeras que hacieron parte de esta trayectoria, y como fuentes secundarias se utilizaron los artículos y libros sobre el temática. Los resultados demuestran que el hospital, desde su fundación sufrió varias alteraciones en función de su misión y de las condiciones contextuales de trabajo. Fueron muchos los problemas administrativos enfrentados por los profisionales de enfermería. A razón de los hallazgos fue evidente el hecho de que la discusión de la racionalidad asistencial, las condiciones de trabajo y la posible autonomía profesional representan un avance importante para la comprensión del presente y la proyección del futuro servicio de enfermería del Hospital.

  3. Looking for plausibility

    CERN Document Server

    Abdullah, Wan Ahmad Tajuddin Wan

    2010-01-01

    In the interpretation of experimental data, one is actually looking for plausible explanations. We look for a measure of plausibility, with which we can compare different possible explanations, and which can be combined when there are different sets of data. This is contrasted to the conventional measure for probabilities as well as to the proposed measure of possibilities. We define what characteristics this measure of plausibility should have. In getting to the conception of this measure, we explore the relation of plausibility to abductive reasoning, and to Bayesian probabilities. We also compare with the Dempster-Schaefer theory of evidence, which also has its own definition for plausibility. Abduction can be associated with biconditionality in inference rules, and this provides a platform to relate to the Collins-Michalski theory of plausibility. Finally, using a formalism for wiring logic onto Hopfield neural networks, we ask if this is relevant in obtaining this measure.

    Maria Reiche was a German mathematician and archaeologist that, from 1940, devoted her life to the study of the Nazca Lines, the most famous Peruvian geoglyphs, gaining recognition and preservation of them. Created by removing the upper most layer of the arid soil of the Nazca desert, these geoglyphs, declared in 1995 a UNESCO World Heritage Site, are composed by very long straight and trapezoidal lines, spirals and large figures representing animals.

    2002-01-01

    The eruption of Santa Maria volcano in 1902 was one of the largest eruptions of the 20th century, forming a large crater on the mountain's southwest flank. Since 1922, a lava-dome complex, Santiaguito, has been forming in the 1902 crater. Growth of the dome has produced pyroclastic flows as recently as the 2001-they can be identified in this image. The city of Quezaltenango (approximately 90,000 people in 1989) sits below the 3772 m summit. The volcano is considered dangerous because of the possibility of a dome collapse such as one that occurred in 1929, which killed about 5000 people. A second hazard results from the flow of volcanic debris into rivers south of Santiaguito, which can lead to catastrophic flooding and mud flows. More information on this volcano can be found at web sites maintained by the Smithsonian Institution, Volcano World, and Michigan Tech University. ISS004-ESC-7999 was taken 17 February 2002 from the International Space Station using a digital camera. The image is provided by the Earth Sciences and Image Analysis Laboratory at Johnson Space Center.

    In this paper, we show that the marginal distribution of plausible values is a consistent estimator of the true latent variable distribution, and, furthermore, that convergence is monotone in an embedding in which the number of items tends to infinity. We use this result to clarify some of the misconceptions that exist about plausible values, and also show how they can be used in the analyses of educational surveys.

  1. Plausibility functions and exact frequentist inference

    CERN Document Server

    Martin, Ryan

    2012-01-01

    In the frequentist program, inferential methods with exact control on error rates are a primary focus. Methods based on asymptotic distribution theory may not be suitable in a particular problem, in which case, a numerical method is needed. This paper presents a general, Monte Carlo-driven framework for the construction of frequentist procedures based on plausibility functions. It is proved that the suitably defined plausibility function-based tests and confidence regions have desired frequentist properties. Moreover, in an important special case involving likelihood ratios, conditions are given such that the plausibility function behaves asymptotically like a consistent Bayesian posterior distribution. An extension of the proposed method is also given for the case where nuisance parameters are present. A number of examples are given which illustrate the method and demonstrate its strong performance compared to other popular existing methods.

  2. Bisimulation for Single-Agent Plausibility Models

    2013-01-01

    Epistemic plausibility models are Kripke models agents use to reason about the knowledge and beliefs of themselves and each other. Restricting ourselves to the single-agent case, we determine when such models are indistinguishable in the logical language containing conditional belief, i.e., we...... define a proper notion of bisimulation, and prove that bisimulation corresponds to logical equivalence on image-finite models. We relate our results to other epistemic notions, such as safe belief and degrees of belief. Our results imply that there are only finitely many non-bisimilar single......-agent epistemic plausibility models on a finite set of propositions. This gives decidability for single-agent epistemic plausibility planning....

  6. Rotational properties of the Maria asteroid family

    2014-07-01

    Introduction: The Maria family is regarded as an old-type (˜3 ± 1 Gyr) [1] asteroid family which has experienced substantial collisional and dynamical evolution in the main belt. It is located near the 3:1 Jupiter mean-motion resonance area that supplies near-Earth asteroids (NEAs) to the inner Solar System. Observations: We carried out observations of Maria family asteroids in 134 nights from July 2008 to May 2013 using 0.5-m to 2-m class telescopes at seven observatories in the northern hemisphere, and derived synodic rotational periods for 51 objects, including new periods for 34 asteroids [2]. Results: We found that there is a significant excess of fast and slow rotators in the observed rotation-rate distribution. From the correlations among rotational periods, the amplitudes of lightcurves, and the sizes, we conclude that the rotational properties of the Maria family asteroids have been changed considerably by non-gravitational forces such as the YORP effect. Using the lightcurve inversion method [3,4], we successfully determined pole orientations for 13 Maria members, and found an excess of prograde spins over retrograde spins with a ratio (N_p/N_r) of 3. This implies that the retrograde rotators could have been ejected by the 3:1 resonance into the inner Solar System since the formation of the Maria family. We estimate that approximately 37 to 75 Maria family asteroids larger than 1 km have entered the near-Earth space as per 100 Myr [2].

    With the increasing clinical use of 3D surface scanners, there is a need for accurate and reliable algorithms that can produce anatomically plausible surfaces. In this paper, a combined method for surface alignment and reconstruction is proposed. It is based on an implicit surface representation...... combined with a Markov Random Field regularisation method. Conceptually, the method maintains an implicit ideal description of the sought surface. This implicit surface is iteratively updated by realigning the input point sets and Markov Random Field regularisation. The regularisation is based on a prior...... energy that has earlier proved to be particularly well suited for human surface scans. The method has been tested on full cranial scans of ten test subjects and on several scans of the outer human ear....

  17. Invariant visual object recognition: biologically plausible approaches.

    Science.gov (United States)

    Robinson, Leigh; Rolls, Edmund T

    2015-10-01

    Key properties of inferior temporal cortex neurons are described, and then, the biological plausibility of two leading approaches to invariant visual object recognition in the ventral visual system is assessed to investigate whether they account for these properties. Experiment 1 shows that VisNet performs object classification with random exemplars comparably to HMAX, except that the final layer C neurons of HMAX have a very non-sparse representation (unlike that in the brain) that provides little information in the single-neuron responses about the object class. Experiment 2 shows that VisNet forms invariant representations when trained with different views of each object, whereas HMAX performs poorly when assessed with a biologically plausible pattern association network, as HMAX has no mechanism to learn view invariance. Experiment 3 shows that VisNet neurons do not respond to scrambled images of faces, and thus encode shape information. HMAX neurons responded with similarly high rates to the unscrambled and scrambled faces, indicating that low-level features including texture may be relevant to HMAX performance. Experiment 4 shows that VisNet can learn to recognize objects even when the view provided by the object changes catastrophically as it transforms, whereas HMAX has no learning mechanism in its S-C hierarchy that provides for view-invariant learning. This highlights some requirements for the neurobiological mechanisms of high-level vision, and how some different approaches perform, in order to help understand the fundamental underlying principles of invariant visual object recognition in the ventral visual stream.

  20. Plausibility and evidence: the case of homeopathy.

    Science.gov (United States)

    Rutten, Lex; Mathie, Robert T; Fisher, Peter; Goossens, Maria; van Wassenhoven, Michel

    2013-08-01

    Homeopathy is controversial and hotly debated. The conclusions of systematic reviews of randomised controlled trials of homeopathy vary from 'comparable to conventional medicine' to 'no evidence of effects beyond placebo'. It is claimed that homeopathy conflicts with scientific laws and that homoeopaths reject the naturalistic outlook, but no evidence has been cited. We are homeopathic physicians and researchers who do not reject the scientific outlook; we believe that examination of the prior beliefs underlying this enduring stand-off can advance the debate. We show that interpretations of the same set of evidence--for homeopathy and for conventional medicine--can diverge. Prior disbelief in homeopathy is rooted in the perceived implausibility of any conceivable mechanism of action. Using the 'crossword analogy', we demonstrate that plausibility bias impedes assessment of the clinical evidence. Sweeping statements about the scientific impossibility of homeopathy are themselves unscientific: scientific statements must be precise and testable. There is growing evidence that homeopathic preparations can exert biological effects; due consideration of such research would reduce the influence of prior beliefs on the assessment of systematic review evidence.

  2. Maria Montessori a different children glance

    2015-02-01

    Full Text Available Maria Montessori was  one of the most important female figures in the 20th-century Italian pedagogical overview. She deeply examined the child and his/her “absorbing” mind in a way that clarified the significant role played by the environment in cognitive and emotional education. Il metodo della pedagogia scientifica (1909 was her first study where she pointed out that science should analyse how the child’s personality develops in social interaction. Maria Montessori claimed children’s rights with respect to the adults’ world by underlining the traditional error -in psychological and educational terms-which used to compel the child to act not complying with his/her own nature. To this end, she organized the child’s educational context-that is the kindergarten- like an ideal place where the child could live his/her educational experiences by freely acting and by being appropriately stimulated. Montessori’s thought has led to fruitful implications related to such pedagogical topics as those currently tackled in contemporary pedagogy: i.e.: the relation between environment and education, the  organization of the teaching and  learning process, the use of procedures, methodologies and materials designed for a relevant pedagogical intervention.How to reference this articleBosna, V.

Predicting all lensing effects requires knowledge of the total lens potential: in this work we give analytic forms for that of the above hybrid model. Emphasizing that complex lens potentials can be constructed from simpler components in linear combination, we provide a recipe for attaining elliptical symmetry in either projected mass or lens potential.We also provide analytic formulae for the lens potentials of Sersic profiles for integer and half-integer index. We then present formulae describing the gravitational lensing effects due to smoothly-truncated universal density profiles in cold dark matter model. For our isolated haloes the density profile falls off as radius to the minus fifth or seventh power beyond the tidal radius, functional forms that allow all orders of lens potential derivatives to be calculated analytically, while ensuring a non-divergent total mass. We show how the observables predicted by this profile differ from that of the original infinite-mass NFW profile. Expressions for the gravitational flexion are highlighted. We show how decreasing the tidal radius allows stripped haloes to be modeled, providing a framework for a fuller investigation of dark matter substructure in galaxies and clusters. Finally we remark on the need for finite mass halo profiles when doing cosmological ray-tracing simulations, and the need for readily-calculable higher order derivatives of the lens potential when studying catastrophes in strong lenses.

    Full Text Available On Maria Montessori (1870-1952, Italian educator of the twentieth century the most successful in the world, there is, also a growing if belated, interest in more recent times also in Italy. So to confine ourselves to two thousand years, studies have appeared on his life and works of great interest, finally showing that its value is recognized beyond resistance of the idealistic and Catholic area survived for a long time. The author investigates these new frontiers of research on the Montessori starting from a new biography dedicated to her which gives attention also to the Indian period.

    Previous studies have shown that a plausible preview word can facilitate the processing of a target word as compared to an implausible preview word (a plausibility preview benefit effect) when reading Chinese (Yang, Wang, Tong, & Rayner, 2012; Yang, 2013). Regarding the nature of this effect, it is possible that readers processed the meaning of the plausible preview word and did not actually encode the target word (given that the parafoveal preview word lies close to the fovea). The current experiment examined this possibility with three conditions wherein readers received a preview of a target word that was either (1) identical to the target word (identical preview), (2) a plausible continuation of the pre-target text, but the post-target text in the sentence was incompatible with it (initially plausible preview), or (3) not a plausible continuation of the pre-target text, nor compatible with the post-target text (implausible preview). Gaze durations on target words were longer in the initially plausible condition than the identical condition. Overall, the results showed a typical preview benefit, but also implied that readers did not encode the initially plausible preview. Also, a plausibility preview benefit was replicated: gaze durations were longer with implausible previews than the initially plausible ones. Furthermore, late eye movement measures did not reveal differences between the initially plausible and the implausible preview conditions, which argues against the possibility of misreading the plausible preview word as the target word. In sum, these results suggest that a plausible preview word provides benefit in processing the target word as compared to an implausible preview word, and this benefit is only present in early but not late eye movement measures.

  11. Lunar maria - result of mantle plume activity?

    Science.gov (United States)

    Sharkov, E.

    It is generally accepted that lunar maria are the result of catastrophic impact events. However, comparative studying of the Earth's and the Moon's tectonomagmatic evolution could evidence about another way of these specific structures origin. Such studies showed that the both planetary bodies evolved on the close scenario: their geological development began after solidification of global magmatic oceans which led to appearance of their primordial crusts: granitic on the Earth and anorthositic - on the Moon. The further evolution of the both bodies occurred in two stages. For their first stages, lasted ˜2.5 mlrd. years on the Earth and ˜1.5 mlrd. years on the Moon, were typical melts, generated in depleted mantle (Bogatikov et al., 2000). However, at the boundary 2.2-2.0 Ga ago on the Earth and 3.9-3.8 Ga on the Moon another type of magmas appeared: geochemical enriched Fe-Ti picrites and basalts, characteristic for the terrestrial Phanerozoic plume-related situations, and basaltic mare magmatism with high-Ti varieties on the Moon. It suggests that evolution of the Earth's magmatism was linked with ascending of mantle plumes (superplumes) of two generation: (1) generated in the mantle, depleted during solidification of magmatic ocean and Archean magmatic activity, and (2) generated at the core-mantle boundary (CMB). The latter were enriched in the mantle fluid components (Fe, Ti, alkalies, etc); this lighter material could ascend to shallower depths, leading to change of tectonic processes, in particular, to appearance of plate tectonics as the major type of tectonomagmatic activity till now (Bogatikov et al., 2000). By analogy to the Earth, magmatism of the Moon was also linked with ascending of mantle plumes: (1) generated in the depleted mantle (magnesian suite) and (2) generated at the lunar CMB with liquid at that time metallic core (mare basalt and picrites with high-Ti varieties). Like on the Earth, these plumes were lighter than the older plumes, and

    Rasch modeling and plausible values methodology were used to scale and report the results of the Organization for Economic Cooperation and Development's Programme for International Student Achievement (PISA). This article will describe the scaling approach adopted in PISA. In particular it will focus on the use of plausible values, a multiple imputation approach that is now commonly used in large-scale assessment. As with all imputation models the plausible values must be generated using models that are consistent with those used in subsequent data analysis. In the case of PISA the plausible value generation assumes a flat linear regression with all students' background variables collected through the international student questionnaire included as regressors. Further, like most linear models, homoscedasticity and normality of the conditional variance are assumed. This article will explore some of the implications of this approach. First, we will discuss the conditions under which the secondary analyses on variables not included in the model for generating the plausible values might be biased. Secondly, as plausible values were not drawn from a multi-level model, the article will explore the adequacy of the PISA procedures for estimating variance components when the data have a hierarchical structure.

  20. Maria Goeppert Mayer and the Nobel Prize

    Science.gov (United States)

    Johnson, Karen E.

    2013-04-01

    When Maria Goeppert Mayer was awarded the Nobel Prize in Physics in 1963, she was only the second woman to receive that award and there have been no additional female physics laureates since. Mayer was uniquely prepared to carry out her prize-winning work on the nuclear shell model. Furthermore, she worked with some of the most well-known figures in mid-twentieth century physics, and her award came at a time when American science was in ascendance. Why, then, is her name so little known beyond the physics community? There are several possible answers to this question, ranging from the personal (her modest reaction to public acclaim) and the scientific (the mathematically abstract nature of her prize-winning work), to the national (the nature of the issues commanding public attention in the 1960s). In this talk I will present an overview of the circumstances that enabled Mayer to make exceptional contributions to nuclear physics, and then examine some of the possible reasons why her exceptional status is not more widely known.

    The empress and queen Maria Theresa Habsburg-Lorraine (May 13th, 1917-November 29th, 1780) bore sixteen children in the marriage with the emperor Franz I Stepha and was famous as "mother-in-law of Europe". Her brother Leopold died immediately after he was born, her sister Amalia died in the cradle and Maria Ana died of perinatal complications at the birth of a dead infant in 1744. The famous hereditary facial dysmorphia of the "Hasburg jawe" wasn't noticed in Maria Theresa's surviving children. In October of 1738, after giving birth to her daughter Ana, a manual lysis of the placenta was performed due to the retained placenta and postpartal bleeding. In 1741 her daughter Carolina died, and in 1767 her daughter Josepha died of small pox. Her daughter Elizabeth remained deformed by the pock marks, and Maria Christina got a puerperal sepsis, but surprisingly, didn't die. Maria Antoinette ended under a guillotine in France, along with her husband Luis XVI. Maria Theresa's father, Karl VI died of the cholecystopankreatitis and peritonitis, and her husband and co-ruler most probably died of acute coronary incident in August 18th, 1765. After her husband's death she started suffering from depression with steady necrophile obsessions. Maria Theresa suffered from a chronical obstructional pulmonary disease (asthma), rehumatic syndromes, hypertension and anxiodepressive syndromes. In 1767 she had small pox. In November 11th 1780 she caught a cold which grew into a pneumonia with high fever. She died of cardiopulmonal dedompensation preceded by pneumonia and asthma.

  2. Some Remarks on the Model Theory of Epistemic Plausibility Models

    CERN Document Server

    Demey, Lorenz

    2010-01-01

    Classical logics of knowledge and belief are usually interpreted on Kripke models, for which a mathematically well-developed model theory is available. However, such models are inadequate to capture dynamic phenomena. Therefore, epistemic plausibility models have been introduced. Because these are much richer structures than Kripke models, they do not straightforwardly inherit the model-theoretical results of modal logic. Therefore, while epistemic plausibility structures are well-suited for modeling purposes, an extensive investigation of their model theory has been lacking so far. The aim of the present paper is to fill exactly this gap, by initiating a systematic exploration of the model theory of epistemic plausibility models. Like in 'ordinary' modal logic, the focus will be on the notion of bisimulation. We define various notions of bisimulations (parametrized by a language L) and show that L-bisimilarity implies L-equivalence. We prove a Hennesy-Milner type result, and also two undefinability results. ...

  3. The Plausibility of a String Quartet Performance in Virtual Reality.

    We describe an experiment that explores the contribution of auditory and other features to the illusion of plausibility in a virtual environment that depicts the performance of a string quartet. 'Plausibility' refers to the component of presence that is the illusion that the perceived events in the virtual environment are really happening. The features studied were: Gaze (the musicians ignored the participant, the musicians sometimes looked towards and followed the participant's movements), Sound Spatialization (Mono, Stereo, Spatial), Auralization (no sound reflections, reflections corresponding to a room larger than the one perceived, reflections that exactly matched the virtual room), and Environment (no sound from outside of the room, birdsong and wind corresponding to the outside scene). We adopted the methodology based on color matching theory, where 20 participants were first able to assess their feeling of plausibility in the environment with each of the four features at their highest setting. Then five times participants started from a low setting on all features and were able to make transitions from one system configuration to another until they matched their original feeling of plausibility. From these transitions a Markov transition matrix was constructed, and also probabilities of a match conditional on feature configuration. The results show that Environment and Gaze were individually the most important factors influencing the level of plausibility. The highest probability transitions were to improve Environment and Gaze, and then Auralization and Spatialization. We present this work as both a contribution to the methodology of assessing presence without questionnaires, and showing how various aspects of a musical performance can influence plausibility.

    Full Text Available Nicolas-Antoine Taunay, French landscape painter, produced also several portraits during his stay at the Rio de Janeiro Court. In this city, in 1816, he paints the queen Carlota Joaquina and all her daughters. In this group, two portraits have a very special way: the paintings still today catalogued as Maria Francisca and Maria Teresa, but probably being Maria Isabel and Maria Francisca de Assis - princesses that, in this year, left Brazil to marry the Spanish King Fernando VII, and his brother Carlos Maria Isidro de Bourbon. In this article, beyond to describe these portraits (and analyse the identities of the portrayed princesses, I analyse their functions in the Court society and the mains artists of this gender in Europe. I will discuss, as well, the hypothesis about the Taunay choices. In this sense, I will analyse the possible circulation of the typologies of portrait between Italy, Portugal, Spain and France, understanding these productions by Taunay and the functions occupied by these portraits in the political relations between Brazil and Europe.

  10. Classification using sparse representations: a biologically plausible approach.

    Science.gov (United States)

    Spratling, M W

    2014-02-01

    Representing signals as linear combinations of basis vectors sparsely selected from an overcomplete dictionary has proven to be advantageous for many applications in pattern recognition, machine learning, signal processing, and computer vision. While this approach was originally inspired by insights into cortical information processing, biologically plausible approaches have been limited to exploring the functionality of early sensory processing in the brain, while more practical applications have employed non-biologically plausible sparse coding algorithms. Here, a biologically plausible algorithm is proposed that can be applied to practical problems. This algorithm is evaluated using standard benchmark tasks in the domain of pattern classification, and its performance is compared to a wide range of alternative algorithms that are widely used in signal and image processing. The results show that for the classification tasks performed here, the proposed method is competitive with the best of the alternative algorithms that have been evaluated. This demonstrates that classification using sparse representations can be performed in a neurally plausible manner, and hence, that this mechanism of classification might be exploited by the brain.

    CERN will be celebrating its 60th anniversary this year. That means 60 years of pioneering scientific research and exciting discoveries. Two Italian physicists, Maria and Giuseppe Fidecaro, remember nearly all of it since they arrived in 1956. Most impressively, they are still hard at work, every day!   Giuseppe and Maria Fidecaro in Restaurant No. 1, at CERN, in 2014, 60 years after they joined the Organization. The couple is easy to spot, even in the cafeteria during busy lunchtimes, where they usually engage in the liveliest discussions. “We argue quite a lot,” Maria tells me with a big smile. “We have very different styles.” “But in general, in the end, we agree,” completes Giuseppe. In October 1954, Giuseppe went to the University of Liverpool as a CERN Fellow to do research at its brand new synchrocyclotron. Maria also joined, having obtained a fellowship from the International Federation of University Women. After getting m...

  3. Families of Plausible Solutions to the Puzzle of Boyajian's Star

    2016-01-01

    Good explanations for the unusual light curve of Boyajian's Star have been hard to find. Recent results by Montet & Simon lend strength and plausibility to the conclusion of Schaefer that in addition to short-term dimmings, the star also experiences large, secular decreases in brightness on decadal timescales. This, combined with a lack of long-wavelength excess in the star's spectral energy distribution, strongly constrains scenarios involving circumstellar material, including hypotheses invoking a spherical cloud of artifacts. We show that the timings of the deepest dimmings appear consistent with being randomly distributed, and that the star's reddening and narrow sodium absorption is consistent with the total, long-term dimming observed. Following Montet & Simon's encouragement to generate alternative hypotheses, we attempt to circumscribe the space of possible explanations with a range of plausibilities, including: a cloud in the outer solar system, structure in the ISM, natural and artificial ma...

    Maintaining an accurate mental representation of the current environment is crucial to detecting change in that environment and ensuring behavioral coherence. Past experience with interactions between objects, such as collisions, has been shown to influence the perception of object interactions. To assess whether mental representations of object interactions derived from experience influence the maintenance of a mental model of the current stimulus environment, we presented physically plausible and implausible collision events while recording brain electrical activity. The parietal P300 response to 'oddball' events was found to be modulated by the physical plausibility of the stimuli, suggesting that past experience of object interactions can influence working memory processes involved in monitoring ongoing changes to the environment.

    Full Text Available Este artigo discute os dados qualitativos da pesquisa “Violência Doméstica perpetrada contra a mulher no município de Montes Claros: um recorte possível”, financiada pelo CNPq e pela FAPEMIG. O objetivo do estudo foi investigar quantitativamente e qualitativamente os atos violentos contra as mulheres na cidade de Montes Claros, Minas Gerais. A vertente qualitativa pretendia conhecer o sentido da violência para as mulheres envolvidas e seus reflexos na família, através de entrevistas semiestruturadas que não se efetivaram. A partir da Análise Institucional de René Lourau analisamos essa inviabilidade como dado qualitativo, examinando o cotidiano da delegacia após a lei Maria da Penha. Concluímos que a intervenção judicial não é suficiente para a inibição da violência contra a mulher, pois em certos casos afasta da delegacia mulheres com outras demandas acerca da violência, que sofrem e que não podem contar com a ajuda policial para a resolução dos seus conflitos.

    Maria Skłodowska Curie left us a great legacy. Her discovery of polonium and radium was incomparably greater than the mere discovery of new elements. Its significance lay in the discovery of a new form of matter, namely radioactive one, but also in her unveiling of the internal property of its atoms. Subsequently emitted radiation went on to play the role of a "natural accelerator" for both scientific research and in medical radiotherapy. It was thanks to these discoveries that the field of nuclear physics arose just a few decades later. As importantly the work of Maria Curie Skłodowska during the Great War demonstrated how important pure scientific discovery can be for society and its welfare.

    Radiography is a healthcare speciality with many technical challenges. Advances in engineering and information technology applications may continue to drive and be driven by radiographers. The world of diagnostic imaging is changing rapidly and radiographers must be proactive in order to survive. To ensure sustainable development, organisations have to identify future opportunities and threats in a timely manner and incorporate them into their strategic planning. Hence, the aim of this study was to analyse and describe plausible scenarios for the radiography profession in 2025. The study has a qualitative design with an inductive approach based on focus group interviews. The interviews were inspired by the Scenario-Planning method. Of the seven trends identified in a previous study, the radiographers considered two as the most uncertain scenarios that would have the greatest impact on the profession should they occur. These trends, labelled "Access to career advancement" and "A sufficient number of radiographers", were inserted into the scenario cross. The resulting four plausible future scenarios were: The happy radiographer, the specialist radiographer, the dying profession and the assembly line. It is suggested that "The dying profession" scenario could probably be turned in the opposite direction by facilitating career development opportunities for radiographers within the profession. Changing the direction would probably lead to a profession composed of "happy radiographers" who are specialists, proud of their profession and competent to carry out advanced tasks, in contrast to being solely occupied by "the assembly line".

    During the origin of life, the biological information of nucleic acid polymers must have increased to encode functional molecules (the RNA world). Ribozymes tend to be compositionally unbiased, as is the vast majority of possible sequence space. However, ribonucleotides vary greatly in synthetic yield, reactivity and degradation rate, and their non-enzymatic polymerization results in compositionally biased sequences. While natural selection could lead to complex sequences, molecules with some activity are required to begin this process. Was the emergence of compositionally diverse sequences a matter of chance, or could prebiotically plausible reactions counter chemical biases to increase the probability of finding a ribozyme? Our in silico simulations using a two-letter alphabet show that template-directed ligation and high concatenation rates counter compositional bias and shift the pool toward longer sequences, permitting greater exploration of sequence space and stable folding. We verified experimentally that unbiased DNA sequences are more efficient templates for ligation, thus increasing the compositional diversity of the pool. Our work suggests that prebiotically plausible chemical mechanisms of nucleic acid polymerization and ligation could predispose toward a diverse pool of longer, potentially structured molecules. Such mechanisms could have set the stage for the appearance of functional activity very early in the emergence of life.

  14. Neural networks, nativism, and the plausibility of constructivism.

    Recent interest in PDP (parallel distributed processing) models is due in part to the widely held belief that they challenge many of the assumptions of classical cognitive science. In the domain of language acquisition, for example, there has been much interest in the claim that PDP models might undermine nativism. Related arguments based on PDP learning have also been given against Fodor's anti-constructivist position--a position that has contributed to the widespread dismissal of constructivism. A limitation of many of the claims regarding PDP learning, however, is that the principles underlying this learning have not been rigorously characterized. In this paper, I examine PDP models from within the framework of Valiant's PAC (probably approximately correct) model of learning, now the dominant model in machine learning, and which applies naturally to neural network learning. From this perspective, I evaluate the implications of PDP models for nativism and Fodor's influential anti-constructivist position. In particular, I demonstrate that, contrary to a number of claims, PDP models are nativist in a robust sense. I also demonstrate that PDP models actually serve as a good illustration of Fodor's anti-constructivist position. While these results may at first suggest that neural network models in general are incapable of the sort of concept acquisition that is required to refute Fodor's anti-constructivist position, I suggest that there is an alternative form of neural network learning that demonstrates the plausibility of constructivism. This alternative form of learning is a natural interpretation of the constructivist position in terms of neural network learning, as it employs learning algorithms that incorporate the addition of structure in addition to weight modification schemes. By demonstrating that there is a natural and plausible interpretation of constructivism in terms of neural network learning, the position that nativism is the only plausible model of

    2015-01-01

    An emerging environmental health issue relates to potential ill-effects of wind turbine noise. There have been numerous suggestions that the low-frequency acoustic components in wind turbine signals can cause symptoms associated with vestibular system disorders, namely vertigo, nausea, and nystagmus. This constellation of symptoms has been labeled as Wind Turbine Syndrome, and has been identified in case studies of individuals living close to wind farms. This review discusses whether it is biologically plausible for the turbine noise to stimulate the vestibular parts of the inner ear and, by extension, cause Wind Turbine Syndrome. We consider the sound levels that can activate the semicircular canals or otolith end organs in normal subjects, as well as in those with preexisting conditions known to lower vestibular threshold to sound stimulation.

  16. Hamiltonian formulation of time-dependent plausible inference

    CERN Document Server

    Davis, Sergio

    2014-01-01

    Maximization of the path information entropy is a clear prescription for performing time-dependent plausible inference. Here it is shown that, following this prescription under the assumption of arbitrary instantaneous constraints on position and velocity, a Lagrangian emerges which determines the most probable trajectory. Deviations from the probability maximum can be consistently described as slices in time by a Hamiltonian, according to a nonlinear Langevin equation and its associated Fokker-Planck equation. The connections unveiled between the maximization of path entropy and the Langevin/Fokker-Planck equations imply that missing information about the phase space coordinate never decreases in time, a purely information-theoretical version of the Second Law of Thermodynamics. All of these results are independent of any physical assumptions, and thus valid for any generalized coordinate as a function of time, or any other parameter. This reinforces the view that the Second Law is a fundamental property of ...

    Pandanus amaryllifolius Roxb. (Pandanaceae) is used as a flavor and in folk medicine in Southeast Asia. The ethanolic crude extract of the aerial parts of P. amaryllifolius exhibited antioxidant, antibiofilm, and anti-inflammatory activities in previous studies. In the current investigation, the purification of the ethanolic extract yielded nine new compounds, including N-acetylnorpandamarilactonines A (1) and B (2); pandalizines A (3) and B (4); pandanmenyamine (5); pandamarilactones 2 (6) and 3 (7), and 5(E)-pandamarilactonine-32 (8); and pandalactonine (9). The isolated alkaloids, with either a γ-alkylidene-α,β-unsaturated-γ-lactone or γ-alkylidene-α,β-unsaturated-γ-lactam system, can be classified into five skeletons including norpandamarilactonine, indolizinone, pandanamine, pandamarilactone, and pandamarilactonine. A plausible biosynthetic route toward 1-5, 7, and 9 is proposed.

    The emerging memristor-based neuromorphic engineering promises an efficient computing paradigm. However, the lack of both internal dynamics in the previous feedforward memristive networks and efficient learning algorithms in recurrent networks, fundamentally limits the learning ability of existing systems. In this work, we propose a framework to support complex learning functions by introducing dedicated learning algorithms to a bio-plausible recurrent memristive network with internal dynamics. We fabricate iron oxide memristor-based synapses, with well controllable plasticity and a wide dynamic range of excitatory/inhibitory connection weights, to build the network. To adaptively modify the synaptic weights, the comprehensive recursive least-squares (RLS) learning algorithm is introduced. Based on the proposed framework, the learning of various timing patterns and a complex spatiotemporal pattern of human motor is demonstrated. This work paves a new way to explore the brain-inspired complex learning in neuromorphic systems.

    2011-05-01

    Full Text Available Abstract Several theories of the underlying mechanisms of Sudden Infant Death Syndrome (SIDS have been proposed. These theories have born relatively narrow beach-head research programs attracting generous research funding sustained for many years at expense to the public purse. This perspective endeavors to critically examine the evidence and bases of these theories and determine their plausibility; and questions whether or not a safe and reasoned hypothesis lies at their foundation. The Opinion sets specific criteria by asking the following questions: 1. Does the hypothesis take into account the key pathological findings in SIDS? 2. Is the hypothesis congruent with the key epidemiological risk factors? 3. Does it link 1 and 2? Falling short of any one of these answers, by inference, would imply insufficient grounds for a sustainable hypothesis. Some of the hypotheses overlap, for instance, notional respiratory failure may encompass apnea, prone sleep position, and asphyxia which may be seen to be linked to co-sleeping. For the purposes of this paper, each element will be assessed on the above criteria.

    Rice is the staple food for more than 50% of the world's population(1-3). Reliable prediction of changes in rice yield is thus central for maintaining global food security. This is an extraordinary challenge. Here, we compare the sensitivity of rice yield to temperature increase derived from field warming experiments and three modelling approaches: statistical models, local crop models and global gridded crop models. Field warming experiments produce a substantial rice yield loss under warming, with an average temperature sensitivity of -5.2 ± 1.4% K(-1). Local crop models give a similar sensitivity (-6.3 ± 0.4% K(-1)), but statistical and global gridded crop models both suggest less negative impacts of warming on yields (-0.8 ± 0.3% and -2.4 ± 3.7% K(-1), respectively). Using data from field warming experiments, we further propose a conditional probability approach to constrain the large range of global gridded crop model results for the future yield changes in response to warming by the end of the century (from -1.3% to -9.3% K(-1)). The constraint implies a more negative response to warming (-8.3 ± 1.4% K(-1)) and reduces the spread of the model ensemble by 33%. This yield reduction exceeds that estimated by the International Food Policy Research Institute assessment (-4.2 to -6.4% K(-1)) (ref. 4). Our study suggests that without CO2 fertilization, effective adaptation and genetic improvement, severe rice yield losses are plausible under intensive climate warming scenarios.

  13. A biologically plausible embodied model of action discovery

    Full Text Available During development, animals can spontaneously discover action-outcomepairings enabling subsequent achievement of their goals. We present abiologically plausible embodied model addressing key aspects of thisprocess. The biomimetic model core comprises the basal ganglia and itsloops through cortex and thalamus. We incorporate reinforcementlearning with phasic dopamine supplying a sensory prediction error,signalling 'surprising' outcomes. Phasic dopamine is used in acorticostriatal learning rule which is consistent with recent data. Wealso hypothesised that objects associated with surprising outcomesacquire 'novelty salience' contingent on the predicability of theoutcome. To test this idea we used a simple model of predictiongoverning the dynamics of novelty salience and phasic dopamine. Thetask of the virtual robotic agent mimicked an in vivo counterpart(Gancarz et al., 2011 and involved interaction with a target objectwhich caused a light flash, or a control object which did not.Learning took place according to two schedules. In one, the phasicoutcome was delivered after interaction with the target in anunpredictable way which emulated the in vivo protocol. Without noveltysalience, the model was unable to account for the experimental data.In the other schedule, the phasic outcome was reliably delivered andthe agent showed a rapid increase in the number of interactions withthe target which then decreased over subsequent sessions. We arguethis is precisely the kind of change in behaviour required torepeatedly present representations of context, action and outcome, toneural networks responsible for learning action-outcome contingency.The model also showed corticostriatal plasticity consistent withlearning a new action in basal ganglia. We conclude that actionlearning is underpinned by a complex interplay of plasticity andstimulus salience, and that our model contains many of the elementsfor biological action discovery to take place.

It has been documented for the treatment of epileptic convulsions at a 200 mg/kg body weight dose. The reported pathogenesis for epileptic convulsions is oxidative stress. Hence, experimental epileptic convulsions via oxidative stress was induced in albino mice epileptic models (maximal electroshock seizure and pentylenetetrazole [PTZ]. A dose concentration equivalent to 2 mg/kg was efficaciously administered in the form of brain-targeted polysorbate-80-coated poly(d,l-lactide-co-glycolide nanoparticles. The nanoparticles were prepared by solvent evaporation technique and further characterized for their physical parameters, in-vitro release kinetics, and in-vivo brain release via various standard methods. Normal β-carotene nanoparticles (BCNP and polysorbate-80-coated β-carotene nanoparticles (P-80-BCNP of 169.8 ± 4.8 nm and 176.3 ± 3.2 nm in size, respectively, were formulated and characterized. Their zeta potential and polydispersity index were subsequently evaluated after 5 months of storage to confirm stability. In vivo activity results showed that a 2 mg unformulated β-carotene dose was ineffective as an anticonvulsant. However, salutary response was reported from BCNP at the same dose, as the hind limb duration decreased significantly in maximal electroshock seizure to 9.30 ± 0.86 seconds, which further decreased with polysorbate-80 coating to 2.10 ± 1.16 seconds as compared to normal control (15.8 ± 1.49 seconds and placebo control (16.50 ± 1.43 seconds.

    Three experiments investigated the malleability of perceived plausibility and the subjective likelihood of occurrence of plausible and implausible events among participants who had no recollection of experiencing them. In Experiment 1, a plausibility-enhancing manipulation (reading accounts of the occurrence of events) combined with a personalized suggestion increased the perceived plausibility of the implausible event, as well as participants' ratings of the likelihood that they had experienced it. Plausibility and likelihood ratings were uncorrelated. Subsequent studies showed that the plausibility manipulation alone was sufficient to increase likelihood ratings but only if the accounts that participants read were set in a contemporary context. These data suggest that false autobiographical beliefs can be induced in clinical and forensic contexts even for initially implausible events.

    Maria Mitchell became Vassar's first Astronomy Professor and Observatory Director in 1865. Her teaching emphasis on students learning by direct observation and analysis is continued today at Vassar College. Several of her students went on to prominence in astronomy, two of them succeeding her at Vassar. Astronomy majors today, both male and female, consistently achieve success after Vassar, in astronomy as well as in other fields. She encouraged her students to present their findings at scientific meetings and in scientific journals, also encouraged today as undergraduates co-author research papers with faculty members. She insisted on excellent facilities and built up the library collection, maintained today to a standard remarkable for a college of just under 2,500 undergraduate students.

    A resolution of the 63rd Assembly of the United Nations proclaimed the year 2011 as the International Year of Chemistry. The coordinators of the event are UNESCO and the International Union of Pure and Applied Chemistry (IUPAC). The patroness of this event is Marie Curie, nee Sklodowska. Among women scientists, she was the first recipient of the Novel Prize, and among all scientists, she is the only one who has received this award in different scientific fields (in 1903 in the field of physics with Pierre Curie and Henri Becquerel, in 1911 in the field of chemistry). Considering the former Polish nationality of Marie Curie, the year 2011 has been proposed by the Polish Parliament as her year, using the name Maria Sklodowska Curie, under which she is known in Poland. Celebrating the International Year of Chemistry is a good opportunity to remember the importance of the work of Maria Sklodowska Curie for the emergence and development of many fields of science. This article is an attempt to present a view of science, as taught through modern applications of the radiation chemistry of polymetric materials and radiation sterilization. Although the real development of both ''cold'' sterilization and polymer technology occurred in the 1950's long after the death of Marie Curie Sklodowska, the original ideas go back to ther work performed in the 1920s. Sometimes, and that is the present case, a single scientist creates a new field, in spite of the fact that at the time of discovery there are no applications. The parallel development of other branches of science and technology helps the application of the original idea. (orig.)

    Full Text Available The Serbian Despot of Ioannina Thomas Preljubović and his wife Maria Angelina Doukaina Palaiologina were frequently connected with religious endowments and artefacts that were donated in churches and monasteries. One of them, an icon of the “Doubting Thomas” with the depiction of Maria Palaiologina among the Apostles, was donated by Maria to the monastery of Metamorphosis (Great Meteoron most probably in the memory of her husband Thomas. This rare iconographic type is traced in post-byzantine painted monuments in Epirus, Thessaly and Macedonia from the sixteenth to the eighteenth century. The transmis­sion of the above iconography is due to the spiritual and artistic influence of two important monastic centers, the Philanthropenos monastery in Ioannina and the Varlaam monastery in Meteora region, whose founders - the Philanthropenos and Apsaras families - were strongly connected to the Serbian rulers of Ioannina and especially Maria Palaiologina.

    Full Text Available The ostracod family Cylindroleberididae is based on the genus Cylindroleberis Brady, 1868, and has a complicated nomenclatural history. The type species of Cylindroleberis is Cypridina mariae Baird, 1850. Baird described only the carapace, which had been considered lost. Thus, there was no reference point for the concept C. mariae or the genus Cylindroleberis. Baird's material has now been found in the Natural History Museum, London, U.K., and is illustrated here. To clarify the taxonomic status of C. mariae and Cylindroleberis, specimens were obtained from near the type locality, and a supplementary description is presented. This includes description of appendages, particularly the first antenna and mandible, which contain important diagnostic characters. This supplementary description provides important information about C. mariae, allowing a revision of the genus Cylindroleberis, and establishing a framework for future biological research on this ostracod group.

    Materials Maria Maya (MMM) is a Guatemalan organization which has dedicated itself to making health education more relevant to the rural Mayans who constitute the majority of Guatemala's population. The administration and direction of the project is in the hands of a team of qualified Mayan men and women. Funding is primarily through various charitable international organizations. The content of preexisting health education programs, strongly influenced by the dominant "ladino" Spanish speaking culture was found to be inappropriate to the goal of this program. MMM set about to formulate a new teaching format which would draw upon, rather than trample over, established cultural practices and life styles. By a process of trial and error, involving small scale field tests, a new program format was developed. By questioning local women about perceived priority areas, through the study of morbidity and mortality data, decisions were made as to topics to be covered. Investigators, authors, and artists worked together to form a "materials package" which was then subject to pretesting. Out of this effort, MMM has been able to come up with a method to encourage more effective participative teaching through the use of education materials.

  20. Electrical conductivity anomalies associated with circular lunar maria

    Dyal, P.; Daily, W. D.

    1979-01-01

    A strong anisotropy is observed in magnetic field fluctuations measured by the Lunokhod 2 magnetometer located on the eastern edge of Mare Serenitatis. This anisotropy can be explained by a regional anomaly in the subsurface electrical conductivity distribution associated with the mare similar to the proposed conductivity anomaly associated with Mare Imbrium. The Serenitatis magnetic field anisotropy is compared to the field fluctuation measured by the Apollo 16 magnetometer 1100 km to the south, and this comparison indicates that the subsurface conductivity distribution can be modeled by a nonconducting layer in the lunar lithosphere which is 150 km thick beneath the highlands and 300 km thick beneath Serenitatis. The decrease in electrical conductivity of the upper mantle beneath the mare may result from lower temperatures due to transport of thermal energy and radioactive heat sources to the surface during mare flooding. This proposed anomaly, along with that proposed for Mare Imbrium, strengthens the possibility of regional anomalies in electrical conductivity associated with all circular lunar maria.

    To discuss the neuropsychiatric phenomena described in Cantigas de Santa Maria (Canticles of St. Mary [CSM]). CSM is a collection of 427 canticles composed in Galician-Portuguese between 1252 and 1284 at the Court of King Alfonso X the Wise of Spain (1221-1284). The canticles (of which 9 are repeated) include devotional and liturgical poems and 353 narrative stories consisting mainly of depictions of Marian miracles. Most are set to music and many are illustrated. We reviewed the canticles for description of miracles and other neuropsychiatric phenomena. Two neurologists reached a consensus about the descriptions. Of the 353 miracles, 279 medically relevant facts (from 187 canticles) and 25 instances of resurrection were reported. Possible neuropsychiatric conditions were described in 98 canticles. Physicians were mentioned in 16 narratives. The most common neurologic conditions detailed were blindness (n = 17), dystonia, weakness, and deformities (n = 20). Other common conditions included psychosis (n = 15), speech disorder/deaf-mutism (n = 12), infections (n = 15), sexual dysfunction/infertility/obstetrical-gynecologic issues (n = 18), head trauma (n = 5), ergotism/St. Anthony's fire (n = 7), and others. There were 9 instances of prodromic mystical experiences/hallucinations heralding death. While limited by retrospection and interpretation of neuropsychiatric phenomena in the medieval context, these short accounts are among the first descriptions of neuropsychiatric conditions in early Portuguese/Galician. They reflect how medieval societies used rational and irrational approaches to understand occurrences in their lives. © 2015 American Academy of Neurology.

Entre suas obras arquitetônicas, a Capela Santa Maria dos Anjos, de 1978, em Vargem Grande Paulista, SP, merece maior atenção. Embora possa ser considerada singela, a Capela é uma obra densa e representativa da Arquitetura Alternativa ao status quo arquitetônico paulista. Este artigo analisa a Capela e sua relação com os conceitos de nacional-popular e Te-Ato, a fé franciscana e as culturas erudita e popular, a fim de contribuir para o melhor entendimento da obra que dialoga com a cena cultural e política da época.

    The informativity of a computational model of language acquisition is directly related to how closely it approximates the actual acquisition task, sometimes referred to as the model's cognitive plausibility. We suggest that though every computational model necessarily idealizes the modeled task, an informative language acquisition model can aim to be cognitively plausible in multiple ways. We discuss these cognitive plausibility checkpoints generally and then apply them to a case study in word segmentation, investigating a promising Bayesian segmentation strategy. We incorporate cognitive plausibility by using an age-appropriate unit of perceptual representation, evaluating the model output in terms of its utility, and incorporating cognitive constraints into the inference process. Our more cognitively plausible model shows a beneficial effect of cognitive constraints on segmentation performance. One interpretation of this effect is as a synergy between the naive theories of language structure that infants may have and the cognitive constraints that limit the fidelity of their inference processes, where less accurate inference approximations are better when the underlying assumptions about how words are generated are less accurate. More generally, these results highlight the utility of incorporating cognitive plausibility more fully into computational models of language acquisition.

  10. The Maria Mitchell Observatory--For Astronomical Research and Public Enlightenment

    2001-04-01

    When the Maria Mitchell Observatory was erected in 1908 to house the 5-inch telescope that had been given Maria Mitchell in 1859, Mrs. Lydia Hinchman, niece of Maria and the principal co-founder of the Maria Mitchell Association, wanted the Observatory to specialize in research while not neglecting public relations entirely. She contacted Professor E. C. Pickering, Director of Harvard College Observatory, for advice. He recommended installing a photographic telescope and having the astronomer specialize in observations of variable asteroids, Eros in particular. Margaret Harwood, one of his assistants at Harvard, was chosen to head the Maria Mitchell Observatory, a post she held for 45 years. Besides lesser contributions, she published a catalogue of 74 asteroids known to have variable brightness. She discovered DF Cygni, an unusual type of variable star with multiple periods, and analyzed its variation on Harvard and Nantucket plates spanning over 50 years. Her final masterpiece was an analysis of 419 variable stars in the Scutum region of the Milky Way, the majority of the variables having been discovered by her High School assistant John Heath. The second Director, Dorrit Hoffleit, instituted a new project, Summer Research Participation on Variable Stars by College Undergraduates, especially women. This project was continued by her successor, Emilia Belserene. Nearly 200 college undergraduates participated in these programs. The fourth Director, Eileen Friel concentrated on both observational and theoretical researches on star clusters, her student contributing few papers on variable stars. The current Direcor, Vladimir Strelnitski, again enthusiasticlly specializes on modern problems of variable stars.

  11. Using critical evaluation to reappraise plausibility judgments: A critical cognitive component of conceptual change

    Science.gov (United States)

    Lombardi, D.

    2011-12-01

    Plausibility judgments-although well represented in conceptual change theories (see, for example, Chi, 2005; diSessa, 1993; Dole & Sinatra, 1998; Posner et al., 1982)-have received little empirical attention until our recent work investigating teachers' and students' understanding of and perceptions about human-induced climate change (Lombardi & Sinatra, 2010, 2011). In our first study with undergraduate students, we found that greater plausibility perceptions of human-induced climate accounted for significantly greater understanding of weather and climate distinctions after instruction, even after accounting for students' prior knowledge (Lombardi & Sinatra, 2010). In a follow-up study with inservice science and preservice elementary teachers, we showed that anger about the topic of climate change and teaching about climate change was significantly related to implausible perceptions about human-induced climate change (Lombardi & Sinatra, 2011). Results from our recent studies helped to inform our development of a model of the role of plausibility judgments in conceptual change situations. The model applies to situations involving cognitive dissonance, where background knowledge conflicts with an incoming message. In such situations, we define plausibility as a judgment on the relative potential truthfulness of incoming information compared to one's existing mental representations (Rescher, 1976). Students may not consciously think when making plausibility judgments, expending only minimal mental effort in what is referred to as an automatic cognitive process (Stanovich, 2009). However, well-designed instruction could facilitate students' reappraisal of plausibility judgments in more effortful and conscious cognitive processing. Critical evaluation specifically may be one effective method to promote plausibility reappraisal in a classroom setting (Lombardi & Sinatra, in progress). In science education, critical evaluation involves the analysis of how evidentiary

    Several studies have shown activation of the mirror neuron system (MNS), comprising the temporal, posterior parietal, and sensorimotor areas when observing plausible actions, but far less is known on how these cortical areas interact during the recognition of a plausible action. Here, we recorded neural activity with magnetoencephalography while subjects viewed point-light displays of biologically plausible and scrambled versions of actions. We were interested in modulations of oscillatory activity and, specifically, in coupling of oscillatory activity between visual and motor areas. Both plausible and scrambled actions elicited modulations of θ (5-7 Hz), α (7-13 Hz), β (13-35 Hz), and γ (55-100 Hz) power within visual and motor areas. When comparing between the two actions, we observed sequential and spatially distinct increases of γ (∼65 Hz), β (∼25 Hz), and α (∼11 Hz) power between 0.5 and 1.3 s in parieto-occipital, sensorimotor, and left temporal areas. In addition, significant clusters of γ (∼65 Hz) and α/β (∼15 Hz) power decrease were observed in right temporal and parieto-occipital areas between 1.3 and 2.0 s. We found β-power in sensorimotor areas to be positively correlated on a trial-by-trial basis with parieto-occipital γ and left temporal α-power for the plausible but not for the scrambled condition. These results provide new insights in the neuronal oscillatory activity of the areas involved in the recognition of plausible action movements and their interaction. The power correlations between specific areas underscore the importance of interactions between visual and motor areas of the MNS during the recognition of a plausible action.

    Full Text Available The objective of this work was to evaluate the performance of 'Rocha' and 'Santa Maria' pears at two planting densities. The experiment was carried out during the 2011/2012, 2012/2013, and 2013/2014 growing seasons, in one-year-old orchards (2011/2012 of 'Rocha' and 'Santa Maria' pears, trained in a central-leader system and planted in two densities (2,000 and 4,000 trees per hectare. The assessed parameters were: production per hectare, production per tree, yield efficiency, number of fruit per tree, average fruit weight, trunk diameter increment, fruit firmness, and soluble solid contents. The cumulative yield of 'Rocha' is greater at the higher planting density, whereas the yield efficiency of 'Santa Maria' increases at the lower planting density, as the trees get more mature. Trunk diameter of 'Rocha' also increases at the lower planting density. However, fruit quality parameters in both cultivars are little affected by planting density.

    Full Text Available To support scientific visualization of multiple-mission data from Mars, the Virtual Astronaut (VA creates an interactive virtual 3D environment built on the Unity3D Game Engine. A prototype study was conducted based on orbital and Opportunity Rover data covering Santa Maria Crater in Meridiani Planum on Mars. The VA at Santa Maria provides dynamic visual representations of the imaging, compositional, and mineralogical information. The VA lets one navigate through the scene and provides geomorphic and geologic contexts for the rover operations. User interactions include in-situ observations visualization, feature measurement, and an animation control of rover drives. This paper covers our approach and implementation of the VA system. A brief summary of the prototype system functions and user feedback is also covered. Based on external review and comments by the science community, the prototype at Santa Maria has proven the VA to be an effective tool for virtual geovisual analysis.

  19. Stereotyping to infer group membership creates plausible deniability for prejudice-based aggression.

    Science.gov (United States)

    Cox, William T L; Devine, Patricia G

    2014-02-01

    In the present study, participants administered painful electric shocks to an unseen male opponent who was either explicitly labeled as gay or stereotypically implied to be gay. Identifying the opponent with a gay-stereotypic attribute produced a situation in which the target's group status was privately inferred but plausibly deniable to others. To test the plausible deniability hypothesis, we examined aggression levels as a function of internal (personal) and external (social) motivation to respond without prejudice. Whether plausible deniability was present or absent, participants high in internal motivation aggressed at low levels, and participants low in both internal and external motivation aggressed at high levels. The behavior of participants low in internal and high in external motivation, however, depended on experimental condition. They aggressed at low levels when observers could plausibly attribute their behavior to prejudice and aggressed at high levels when the situation granted plausible deniability. This work has implications for both obstacles to and potential avenues for prejudice-reduction efforts.

    2011-11-01

    Full Text Available The essay presents a comparison between the thought of Ellen Key and that of Maria Montessori. Changes that involved the role of women, caught in its interdependence with the development of new educational practices, were the center of the theoretical contribution of Ellen Key. Maria Montessori believed that only women work outside the home would guarantee the economic independence necessary to form a union on sentiment rather than on utilitarian calculations and therefore she did not seem to share the concerns of the Key on an increasingly massive female entry into the world of work. The paper offers an updated reflection on the work of two scholars of education.

  1. Conservation of Endangered Lupinus mariae-josephae in Its Natural Habitat by Inoculation with Selected, Native Bradyrhizobium Strains

    Lupinus mariae-josephae is a recently discovered endemism that is only found in alkaline-limed soils, a unique habitat for lupines, from a small area in Valencia region (Spain). In these soils, L. mariae-josephae grows in just a few defined patches, and previous conservation efforts directed towards controlled plant reproduction have been unsuccessful. We have previously shown that L. mariae-josephae plants establish a specific root nodule symbiosis with bradyrhizobia present in those soils, and we reasoned that the paucity of these bacteria in soils might contribute to the lack of success in reproducing plants for conservation purposes. Greenhouse experiments using L. mariae-josephae trap-plants showed the absence or near absence of L. mariae-josephae-nodulating bacteria in “terra rossa” soils of Valencia outside of L. mariae-josephae plant patches, and in other “terra rossa” or alkaline red soils of the Iberian Peninsula and Balearic Islands outside of the Valencia L. mariae-josephae endemism region. Among the bradyrhizobia able to establish an efficient symbiosis with L. mariae-josephae plants, two strains, LmjC and LmjM3 were selected as inoculum for seed coating. Two planting experiments were carried out in consecutive years under natural conditions in areas with edapho-climatic characteristics identical to those sustaining natural L. mariae-josephae populations, and successful reproduction of the plant was achieved. Interestingly, the successful reproductive cycle was absolutely dependent on seedling inoculation with effective bradyrhizobia, and optimal performance was observed in plants inoculated with LmjC, a strain that had previously shown the most efficient behavior under controlled conditions. Our results define conditions for L. mariae-josephae conservation and for extension to alkaline-limed soil habitats, where no other known lupine can thrive. PMID:25019379

  3. Inference and Plausible Reasoning in a Natural Language Understanding System Based on Object-Oriented Semantics

    CERN Document Server

    Ostapov, Yuriy

    2012-01-01

    Algorithms of inference in a computer system oriented to input and semantic processing of text information are presented. Such inference is necessary for logical questions when the direct comparison of objects from a question and database can not give a result. The following classes of problems are considered: a check of hypotheses for persons and non-typical actions, the determination of persons and circumstances for non-typical actions, planning actions, the determination of event cause and state of persons. To form an answer both deduction and plausible reasoning are used. As a knowledge domain under consideration is social behavior of persons, plausible reasoning is based on laws of social psychology. Proposed algorithms of inference and plausible reasoning can be realized in computer systems closely connected with text processing (criminology, operation of business, medicine, document systems).

    In immunization safety research, individuals are considered at risk for the development of certain adverse events following immunization (AEFI) within a specific period of time referred to as the risk interval. These intervals should ideally be determined based on biologic plausibility considering features of the AEFI, presumed or known pathologic mechanism, and the vaccine. Misspecification of the length and timing of these intervals may result in introducing bias in epidemiologic and clinical studies of immunization safety. To date, little work has been done to formally assess and determine biologically plausible and evidence-based risk intervals in immunization safety research. In this report, we present a systematic process to define biologically plausible and evidence-based risk interval estimates for two specific AEFIs, febrile seizures and acute disseminated encephalomyelitis. In addition, we review methodologic issues related to the determination of risk intervals for consideration in future studies of immunization safety.

  5. The semiosis of prayer and the creation of plausible fictional worlds

    Directory of Open Access Journals (Sweden)

    Full Text Available Prayer and incantation can perhaps be said to be 'mechanisms' that promise that lack will be liquidated and that there is an unlimited signator, a father, or some other metaphysical creature, standing behind and legitimizing the discourse. A way of communicating with the Unlimited that is privileged by an interpretive community that read the prayers aloud and enacted the magical stage-scripts. These highly overlapping categories function as one of the most common subforms of religious discourse for the creation, actualization and maintenance of plausible fictional worlds. They are liminal and transitional mechanisms that manipulate an empirical reader to phase-shift from an actual world to a plausible, by being inscribed in a possible and fictional world, thus creating a model reader, that perceives and acts according to the plausible world outlined by a given interpretive community, and that hears god talking in voces magicae and in god-speaking silence.

    波利亚的“合情推理”模式引进我国数学课程标准后,就成了我国数学教育研究的关键词。然而,“合情推理”的科学性尚需考证:(1)它的中文意义不明确;(2)它不满足推理模式的客观性要求,存在明显的缺陷;(3)过分强调“合情推理模式”则是过分强调归纳推理和演绎推理的区别,容易割裂它们之间的关系。%After the model of "plausible inference" being introduced into the mathematics curriculum standards, it became a key word of the research on mathematics education in China. However, there are doubts on whether it is scientific. (1) Chinese meaning of plausible inference is ambiguous. (2) The plausible inference can not meet the objective requirement of the reasoning, which has obvious defects. (3) Overemphasizing the model of plausible inference would overemphasize the difference between deductive inference and inductive inference, and would dispart them.

  1. From bone to plausible bipedal locomotion. Part II: Complete motion synthesis for bipedal primates.

    This paper addresses the problem of synthesizing plausible bipedal locomotion according to 3D anatomical reconstruction and general hypotheses on human motion control strategies. In a previous paper [Nicolas, G., Multon, F., Berillon, G., Marchal, F., 2007. From bone to plausible bipedal locomotion using inverse kinematics. Journal of Biomechanics 40 (5) 1048-1057], we have validated a method based on using inverse kinematics to obtain plausible lower-limb motions knowing the trajectory of the ankle. In this paper, we propose a more general approach that also involves computing a plausible trajectory of the ankles for a given skeleton. The inputs are the anatomical descriptions of the bipedal species, imposed footprints and a rest posture. This process is based on optimizing a reference ankle trajectory until a set of criteria is minimized. This optimization loop is based on the assumption that a plausible motion is supposed to have little internal mechanical work and should be as less jerky as possible. For each tested ankle trajectory, inverse kinematics is used to compute a lower-body motion that enables us to compute the resulting mechanical work and jerk. This method was tested on a set of modern humans (male and female, with various anthropometric properties). We show that the results obtained with this method are close to experimental data for most of the subjects. We also demonstrate that the method is not sensitive to the choice of the reference ankle trajectory; any ankle trajectory leads to very similar result. We finally apply the method to a skeleton of Pan paniscus (Bonobo), and compare the resulting motion to those described by zoologists.

    The article presents from the perspective of one hundred years the work of Maria Curie-Skłodowska, which in many cases was ahead of the state of knowledge of the time. It opened new horizons and for this reason we made many digressions. The fact of awarding her the Nobel Prize twice is a sensation enough to present the values of careful activity of the Nobel Prize Committee that emphasizes the importance of Maria's achievements. A significant element of Maria Skłodowska-Curie's achievements was still mysterious character of the radiation in her time, and only chemical approach made it possible to organise the phenomena and explain the origin of the radiation. The essence of the research was an arduous separation of components following the track of growing radiation of successive fractions of preparations. This research was a start of the technology of educement of dispersed elements in great mass of materials. We underline the paramount role of the chemical research Maria Skłodowska conducted while still in Warsaw in the laboratories of the Museum of Industry and Agriculture under the guidance of an excellent chemist Józef Jerzy Boguski. Her research in Paris was the origin of the semi-commercial scale in chemistry and setting aside a special shed outside the university building was the beginning of the institutes that now function beyond universities and are key element of scientific and technical progress. Technology of splitting developed by Maria Skłodowska-Curie was applied also by other radiochemists, e.g. By Otto Hahn. Lively movement in radiochemistry of her lifetime resulted in Maria's disputes with e.g. German chemist Marckwald, who questioned the originality of polonium. The scientific disputes like this one Maria won triumphantly although in several others she had to accept opponents' argument, as in the case of radon. Her experiments were planned with utmost rationality as it was with the rejection of the hypothesis saying that radioactivity was

  8. Biologically plausible learning in recurrent neural networks reproduces neural dynamics observed during cognitive tasks.

    Science.gov (United States)

    Miconi, Thomas

    2017-02-23

    Neural activity during cognitive tasks exhibits complex dynamics that flexibly encode task-relevant variables. Chaotic recurrent networks, which spontaneously generate rich dynamics, have been proposed as a model of cortical computation during cognitive tasks. However, existing methods for training these networks are either biologically implausible, and/or require a continuous, real-time error signal to guide learning. Here we show that a biologically plausible learning rule can train such recurrent networks, guided solely by delayed, phasic rewards at the end of each trial. Networks endowed with this learning rule can successfully learn nontrivial tasks requiring flexible (context-dependent) associations, memory maintenance, nonlinear mixed selectivities, and coordination among multiple outputs. The resulting networks replicate complex dynamics previously observed in animal cortex, such as dynamic encoding of task features and selective integration of sensory inputs. We conclude that recurrent neural networks offer a plausible model of cortical dynamics during both learning and performance of flexible behavior.

    2012-12-01

    When planning resequencing studies for complex diseases, previous association and linkage studies can constrain the range of plausible genetic models for a given locus. Here, we explore the combinations of causal risk allele frequency (RAFC ) and genotype relative risk (GRRC ) consistent with no or limited evidence for affected sibling pair (ASP) linkage and strong evidence for case-control association. We find that significant evidence for case-control association combined with no or moderate evidence for ASP linkage can define a lower bound for the plausible RAFC . Using data from large type 2 diabetes (T2D) linkage and genome-wide association study meta-analyses, we find that under reasonable model assumptions, 23 of 36 autosomal T2D risk loci are unlikely to be due to causal variants with combined RAFC < 0.005, and four of the 23 are unlikely to be due to causal variants with combined RAFC < 0.05.

    The massive accumulation of biomedical knowledge is reflected by the growth of the literature database MEDLINE with over 23 million bibliographic records. All records are manually indexed by MeSH descriptors, many of them refined by MeSH subheadings. We use subheading information to cluster types of MeSH descriptor co-occurrences in MEDLINE by processing co-occurrence information provided by the UMLS. The goal is to infer plausible predicates to each resulting cluster. In an initial experiment this was done by grouping disease-pharmacologic substance co-occurrences into six clusters. Then, a domain expert manually performed the assignment of meaningful predicates to the clusters. The mean accuracy of the best ten generated biomedical facts of each cluster was 85%. This result supports the evidence of the potential of MeSH subheadings for extracting plausible medical predications from MEDLINE.

    A written single word spelling to dictation test and a single word reading test were given to 68 severe-profoundly oral deaf 10-11-year-old children and 20 hearing children with a diagnosis of dyslexia. The literacy scores of the deaf children and the hearing children with dyslexia were lower than expected for children of their age and did not differ from each other. Three quarters of the spelling errors of hearing children with dyslexia compared with just over half the errors of the oral deaf group were phonologically plausible. Expressive vocabulary and speech intelligibility predicted the percentage of phonologically plausible errors in the deaf group only. Implications of findings for the phonological decoding self-teaching model and for supporting literacy development are discussed.

  12. Of paradox and plausibility: the dynamic of change in medical law.

    Science.gov (United States)

    Harrington, John

    2014-01-01

    This article develops a model of change in medical law. Drawing on systems theory, it argues that medical law participates in a dynamic of 'deparadoxification' and 'reparadoxification' whereby the underlying contingency of the law is variously concealed through plausible argumentation, or revealed by critical challenge. Medical law is, thus, thoroughly rhetorical. An examination of the development of the law on abortion and on the sterilization of incompetent adults shows that plausibility is achieved through the deployment of substantive common sense and formal stylistic devices. It is undermined where these elements are shown to be arbitrary and constructed. In conclusion, it is argued that the politics of medical law are constituted by this antagonistic process of establishing and challenging provisionally stable normative regimes.

    The increase in solar ultraviolet radiation can have various direct and indirect effects on human health, like the incidence of ocular damage. Data of eye damage in residents of three suburban regions in Greece and in two groups of monks/nuns and fishermen are examined here. The statistics performed on these data provides new information about the plausible association between increased levels of solar ultraviolet radiation, air-pollution at ground level, and the development of ocular defects.

    2016-09-01

    Good explanations for the unusual light curve of Boyajian's Star have been hard to find. Recent results by Montet & Simon lend strength and plausibility to the conclusion of Schaefer that in addition to short-term dimmings, the star also experiences large, secular decreases in brightness on decadal timescales. This, combined with a lack of long-wavelength excess in the star's spectral energy distribution, strongly constrains scenarios involving circumstellar material, including hypotheses invoking a spherical cloud of artifacts. We show that the timings of the deepest dimmings appear consistent with being randomly distributed, and that the star's reddening and narrow sodium absorption is consistent with the total, long-term dimming observed. Following Montet & Simon's encouragement to generate alternative hypotheses, we attempt to circumscribe the space of possible explanations with a range of plausibilities, including: a cloud in the outer solar system, structure in the interstellar medium (ISM), natural and artificial material orbiting Boyajian's Star, an intervening object with a large disk, and variations in Boyajian's Star itself. We find the ISM and intervening disk models more plausible than the other natural models.

    Three experiments investigated how font emphasis influences reading and remembering discourse. Although past work suggests that contrastive pitch contours benefit memory by promoting encoding of salient alternatives, it is unclear both whether this effect generalizes to other forms of linguistic prominence and how the set of alternatives is constrained. Participants read discourses in which some true propositions had salient alternatives (e.g., British scientists found the endangered monkey when the discourse also mentioned French scientists) and completed a recognition memory test. In Experiments 1 and 2, font emphasis in the initial presentation increased participants' ability to later reject false statements about salient alternatives but not about unmentioned items (e.g., Portuguese scientists). In Experiment 3, font emphasis helped reject false statements about plausible alternatives, but not about less plausible alternatives that were nevertheless established in the discourse. These results suggest readers encode a narrow set of only those alternatives plausible in the particular discourse. They also indicate that multiple manipulations of linguistic prominence, not just prosody, can lead to consideration of alternatives.

  16. A biologically plausible model of time-scale invariant interval timing.

    Almeida, Rita; Ledberg, Anders

    2010-02-01

    The temporal durations between events often exert a strong influence over behavior. The details of this influence have been extensively characterized in behavioral experiments in different animal species. A remarkable feature of the data collected in these experiments is that they are often time-scale invariant. This means that response measurements obtained under intervals of different durations coincide when plotted as functions of relative time. Here we describe a biologically plausible model of an interval timing device and show that it is consistent with time-scale invariant behavior over a substantial range of interval durations. The model consists of a set of bistable units that switch from one state to the other at random times. We first use an abstract formulation of the model to derive exact expressions for some key quantities and to demonstrate time-scale invariance for any range of interval durations. We then show how the model could be implemented in the nervous system through a generic and biologically plausible mechanism. In particular, we show that any system that can display noise-driven transitions from one stable state to another can be used to implement the timing device. Our work demonstrates that a biologically plausible model can qualitatively account for a large body of data and thus provides a link between the biology and behavior of interval timing.

    The page written by the astronomer Francesco Bianchini (1662-1729) and containing the data of the 1701 winter solstice observed at Santa Maria degli Angeli is presented for the first time in figure 2 and widely discussed along this paper. The great meridian line in the Basilica of Santa Maria degli Angeli in Rome was built in 1701/1702 with the scope to measure the Obliquity of the Earth's orbit in the following eight centuries, upon the will of pope Clement XI. During the winter solstice of 1701 the first measurements of the obliquity have been realized by Francesco Bianchini, the astronomer who designed the meridian line, upgrading the similar instrument realized by Giandomenico Cassini in San Petronio, Bononia. In this paper the accuracy of the data observed by Francesco Bianchini is discussed and compared with up-to-date ephemerides. The modern situation of this historical instrument is also presented.

    For many reasons the year 1898 was unusual for Maria Skłodowska-Curie and her husband. After defining the subject of the doctoral thesis and choosing Henri Becqerel as thesis supervisor, Maria started intensive experimental work. In the allotted room called storeroom, in conditions that were far too inadequate, they managed to put up a unique measuring equipment composed of instruments whose originator was Pierre Curie. In the ionization chamber and in the piezoelectric quartz charges formed, whose mutual neutralization was shown by the quadrant electrometer. Ionization current, which was measured quantitatively, was proportional to the radiation of the sample. Studying many elements, their compounds and minerals enabled Maria to state that uranium is not the only element endowed with the power of radiation; the second one turned out to be thorium. Anomaly detected in the radiation of uranium minerals made it possible for Maria to draw an extremely important conclusion: radioactive uranium and thorium are not the only elements endowed with such an attribute. Pitchblende, which was studied by the Curie couple, had to contain also other radioactive substances. Gustave Bémont also participated in the chemical analysis of the uranium ore and it is worth reminding that he was involved in the discovery of polonium and uranium. The phenomenon of radioactivity couldn't have been explained if it was not for the sources of strong radioactivity. Those sources undoubtedly could have been the discovered elements but their scanty content in the uranium ore made their isolation very difficult and laborious. Access to industrial remains after procession of pitchblende from Jachymov (Sankt Joachimstahl), obtained owing to the mediation of Eduard Suess, provided the source of this raw material. From it, in a shack also called le hangar, the Curie couple isolated the first samples of the radium salt. This element, later extracted by discoverers on a grand scale and handed over in a

    This article suggests that the reality of the world is socially constructed through the words and narratives chosen and used. These social constructions may be from science and technology, business and economics, or poetry and metaphors, and as such each shapes a different world. The work of the poet Rainer Maria Rilke is used to illustrate how the power of words and images shape and form the world. The implications of the use of language for the care of souls are discussed.

    The growth and decay of ocean-island volcanoes are intrinsically linked to vertical movements. While the causes for subsidence are better understood, uplift mechanisms remain enigmatic. Santa Maria Island in the Azores Archipelago is an ocean-island volcano resting on top of young lithosphere, barely 480 km away from the Mid-Atlantic Ridge. Like most other Azorean islands, Santa Maria should be experiencing subsidence. Yet, several features indicate an uplift trend instead. In this paper, we reconstruct the evolutionary history of Santa Maria with respect to the timing and magnitude of its vertical movements, using detailed field work and 40Ar/39Ar geochronology. Our investigations revealed a complex evolutionary history spanning ∼6 m.y., with subsidence up to ca. 3.5 Ma followed by uplift extending to the present day. The fact that an island located in young lithosphere experienced a pronounced uplift trend is remarkable and raises important questions concerning possible uplift mechanisms. Localized uplift in response to the tectonic regime affecting the southeastern tip of the Azores Plateau is unlikely, since the area is under transtension. Our analysis shows that the only viable mechanism able to explain the uplift is crustal thickening by basal intrusions, suggesting that intrusive processes play a significant role even on islands standing on young lithosphere, such as in the Azores.

  19. Understanding Karma Police: The Perceived Plausibility of Noun Compounds as Predicted by Distributional Models of Semantic Representation

    2016-01-01

    Noun compounds, consisting of two nouns (the head and the modifier) that are combined into a single concept, differ in terms of their plausibility: school bus is a more plausible compound than saddle olive. The present study investigates which factors influence the plausibility of attested and novel noun compounds. Distributional Semantic Models (DSMs) are used to obtain formal (vector) representations of word meanings, and compositional methods in DSMs are employed to obtain such representations for noun compounds. From these representations, different plausibility measures are computed. Three of those measures contribute in predicting the plausibility of noun compounds: The relatedness between the meaning of the head noun and the compound (Head Proximity), the relatedness between the meaning of modifier noun and the compound (Modifier Proximity), and the similarity between the head noun and the modifier noun (Constituent Similarity). We find non-linear interactions between Head Proximity and Modifier Proximity, as well as between Modifier Proximity and Constituent Similarity. Furthermore, Constituent Similarity interacts non-linearly with the familiarity with the compound. These results suggest that a compound is perceived as more plausible if it can be categorized as an instance of the category denoted by the head noun, if the contribution of the modifier to the compound meaning is clear but not redundant, and if the constituents are sufficiently similar in cases where this contribution is not clear. Furthermore, compounds are perceived to be more plausible if they are more familiar, but mostly for cases where the relation between the constituents is less clear. PMID:27732599

    Full Text Available A novel growth process of silver nanowires was revealed by tracing the morphology evolution of Ag nanostructures fabricated by an improved polyol process. A mixture of Ag nanowires and nanoparticles was obtained with the usage of PVP-K25 (MW = 38,000. The products sampled at different reaction time were studied in detail using UV-visible absorption spectra and transmission electron microscopy (TEM. An interesting phenomenon unknown in the past was observed where Ag nanoparticles undergo an important dissolution-recrystallization process and Ag nanowires are formed at the expense of the preformed Ag nanoparticles. A plausible novel growth mechanism for the silver nanowires was proposed.

    This study introduces a new Generalized Leaky Integrate-and-Fire (GLIF) neuron model. Unlike Normal Leaky Integrate-and-Fire (NLIF) models, the leaking resistor in the GLIF model equation is assumed to be variable, and an additional term would have the bias current added to the model equation in order to improve the accuracy. Adjusting the parameters defined for the leaking resistor and bias current, a GLIF model could be accurately matched to any Hodgkin-Huxley (HH) model and be able to reproduce plausible biological neuron behaviors.

  3. Higher Data Quality by Online Data-Entry and Automated Plausibility Checks

    Long-term phenological observations are now recognized as important indicators for climate change impact studies. With the increased need for phenological data, there is also an increased need for higher data quality. Since 1951 MeteoSwiss has been operating a national phenological observation network. Currently the network consists of about 150 active stations observing up to 69 different phenophases. An important aim of a running three years project at MeteoSwiss is a further increase of the quality of the collected data. The higher data quality will be achieved by an automated procedure performing plausibility checks on the data and by online data-entry. Further measures such as intensified observer instructions and collection of more detailed metadata also contribute to a high data quality standard. The plausibility checks include the natural order of the phenophases within a species and also between different species (with regard to possible natural deviation). Additionally it will be checked if the observed date differs by less than two standard deviations from the average for this phenophase at the altitude of the station. A value outside of these limits is not necessarily a false value, since occurrences of extreme values will be beyond these limits. Therefore, within this check of the limits, the timing of the season of the respective year will also be taken into account. In case of an implausible value a comparison with other stations of the same region and sea level is proposed. A further possibility of data quality control could be to model the different phenophases statistically and to use this model for estimating the likelihood of observed values. An overall exploratory data analysis is currently performed providing a solid basis to implement the best possible methods for the plausibility checks. Important advantages of online data-entry are the near real-time availability of the data as well as the avoidance of various kinds of typical mistakes

    Empirical models are frequently applied to produce landslide susceptibility maps for large areas. Subsequent quantitative validation results are routinely used as the primary criteria to infer the validity and applicability of the final maps or to select one of several models. This study hypothesizes that such direct deductions can be misleading. The main objective was to explore discrepancies between the predictive performance of a landslide susceptibility model and the geomorphic plausibility of subsequent landslide susceptibility maps while a particular emphasis was placed on the influence of incomplete landslide inventories on modelling and validation results. The study was conducted within the Flysch Zone of Lower Austria (1,354 km2) which is known to be highly susceptible to landslides of the slide-type movement. Sixteen susceptibility models were generated by applying two statistical classifiers (logistic regression and generalized additive model) and two machine learning techniques (random forest and support vector machine) separately for two landslide inventories of differing completeness and two predictor sets. The results were validated quantitatively by estimating the area under the receiver operating characteristic curve (AUROC) with single holdout and spatial cross-validation technique. The heuristic evaluation of the geomorphic plausibility of the final results was supported by findings of an exploratory data analysis, an estimation of odds ratios and an evaluation of the spatial structure of the final maps. The results showed that maps generated by different inventories, classifiers and predictors appeared differently while holdout validation revealed similar high predictive performances. Spatial cross-validation proved useful to expose spatially varying inconsistencies of the modelling results while additionally providing evidence for slightly overfitted machine learning-based models. However, the highest predictive performances were obtained for

    Full Text Available Visual object recognition occurs easily despite differences in position, size, and rotation of the object, but the neural mechanisms responsible for this invariance are not known. We have found a set of transforms that achieve invariance in a neurally plausible way. We find that a transform based on local spatial frequency analysis of oriented segments and on logarithmic mapping, when applied twice in an iterative fashion, produces an output image that is unique to the object and that remains constant as the input image is shifted, scaled or rotated.

    2013-01-01

    Biosignature gas detection is one of the ultimate future goals for exoplanet atmosphere studies. We have created a framework for linking biosignature gas detectability to biomass estimates, including atmospheric photochemistry and biological thermodynamics. The new framework is intended to liberate predictive atmosphere models from requiring fixed, Earth-like biosignature gas source fluxes. New biosignature gases can be considered with a check that the biomass estimate is physically plausible. We have validated the models on terrestrial production of NO, H2S, CH4, CH3Cl, and DMS. We have applied the models to propose NH3 as a biosignature gas on a "cold Haber World," a planet with a N2-H2 atmosphere, and to demonstrate why gases such as CH3Cl must have too large of a biomass to be a plausible biosignature gas on planets with Earth or early-Earth-like atmospheres orbiting a Sun-like star. To construct the biomass models, we developed a functional classification of biosignature gases, and found that gases (such...

  8. Self-assembly of phosphate amphiphiles in mixtures of prebiotically plausible surfactants.

    The spontaneous formation of closed bilayer structures from prebiotically plausible amphiphiles is an essential requirement for the emergence of early cells on prebiotic Earth. The sources of amphiphiles could have been both endo- and exogenous (accretion of meteorite carbonaceous material or interstellar dust particles). Among all prebiotic possible amphiphile candidates, those containing phosphate are the least investigated species because their self-assembly occurs in a seemingly too narrow range of conditions. The self-assembly of simple phosphate amphiphiles should, however, be of great interest, as contemporary membranes predominantly contain phospholipids. In contrast to common expectations, we show that these amphiphiles can be easily synthesized under prebiotically plausible environmental conditions and can efficiently form bilayer structures in the presence of various co-surfactants across a large range of pH values. Vesiculation was even observed in crude reaction mixtures that contained 1-decanol as the amphiphile precursor. The two best co-surfactants promoted vesicle formation over the entire pH range in aqueous solutions. Expanding the pH range where bilayer membranes self-assemble and remain intact is a prerequisite for the emergence of early cell-like compartments and their preservation under fluctuating environmental conditions. These mixed bilayers also retained small charged solutes, such as dyes. These results demonstrate that alkyl phosphate amphiphiles might have played a significant role as early compartment building blocks.

  9. A swarm intelligence framework for reconstructing gene networks: searching for biologically plausible architectures.

    Kentzoglanakis, Kyriakos; Poole, Matthew

    2012-01-01

    In this paper, we investigate the problem of reverse engineering the topology of gene regulatory networks from temporal gene expression data. We adopt a computational intelligence approach comprising swarm intelligence techniques, namely particle swarm optimization (PSO) and ant colony optimization (ACO). In addition, the recurrent neural network (RNN) formalism is employed for modeling the dynamical behavior of gene regulatory systems. More specifically, ACO is used for searching the discrete space of network architectures and PSO for searching the corresponding continuous space of RNN model parameters. We propose a novel solution construction process in the context of ACO for generating biologically plausible candidate architectures. The objective is to concentrate the search effort into areas of the structure space that contain architectures which are feasible in terms of their topological resemblance to real-world networks. The proposed framework is initially applied to the reconstruction of a small artificial network that has previously been studied in the context of gene network reverse engineering. Subsequently, we consider an artificial data set with added noise for reconstructing a subnetwork of the genetic interaction network of S. cerevisiae (yeast). Finally, the framework is applied to a real-world data set for reverse engineering the SOS response system of the bacterium Escherichia coli. Results demonstrate the relative advantage of utilizing problem-specific knowledge regarding biologically plausible structural properties of gene networks over conducting a problem-agnostic search in the vast space of network architectures.

    Reptile prime ministers and flying Nazi saucers-extreme and sometimes off-wall conclusion are typical ingredients of conspiracy theories. While individual differences are a common research topic concerning conspiracy theories, the role of extreme statements in the process of acquiring and passing on conspiratorial stories has not been regarded in an experimental design so far. We identified six morphological components of conspiracy theories empirically. On the basis of these content categories a set of narrative elements for a 9/11 story was compiled. These elements varied systematically in terms of conspiratorial allegation, i.e., they contained official statements concerning the events of 9/11, statements alleging to a conspiracy limited in time and space as well as extreme statements indicating an all-encompassing cover-up. Using the method of narrative construction, 30 people were given a set of cards with these statements and asked to construct the course of events of 9/11 they deem most plausible. When extreme statements were present in the set, the resulting stories were more conspiratorial; the number of official statements included in the narrative dropped significantly, whereas the self-assessment of the story's plausibility did not differ between conditions. This indicates that blatant statements in a pool of information foster the synthesis of conspiracy theories on an individual level. By relating these findings to one of Germany's most successful (and controversial) non-fiction books, we refer to the real-world dangers of this effect.

    Background: Refractive errors are among the most frequent reasons for demand of eye-care services. Publications on refractive errors prevalence in our country are few. This study has the purpose to assess the prevalence of refractive errors in an adult population of Villa Maria, Córdoba, Argentina. Methods: The Villa Maria Eye Study is a population-based cross-sectional study conducted in the city of Villa Maria, Córdoba, Argentina from May 2008 to November 2009. Subject’s aged 40+ received a demographic interview and complete ophthalmological exam. Visual acuity was obtained with an ETDRS chart. Cycloplegic auto refraction was performed. The spherical equivalent was highly correlated between right and left eyes, so only data of right eyes are presented. Myopia and hyperopia were defined with a ±0.50 diopters (D) criterion and astigmatism >1 D. Results: This study included 646 subjects, aged 40 to 90 (mean age: 59.6±10.3 years old). Four hundred and sixty two (71.5%) were females. The mean spherical equivalent was +0.714±2.41 D (range, −22.00 to+8.25 D) and the power of the cylinder was, on average, −0.869±0.91 D (range, 0 to −6.50 D). In this sample, 61.6% subjects were hyperopic, and 13.5% were myopic. Myopia prevalence was lower in men (9.8% versus 14.9%) but this difference among genders was not statistically signiifcant. There were 141 subjects (21.8%) with anisometropia greater than 1 D, and 168 subjects (26.0%) with astigmatism greater than 1 D. Conclusions: The present study shows the prevalence of cycloplegic refractive errors in an adult population of Argentina. The prevalence of hyperopia was high, while myopia prevalence was very low.

    Oceanic volcanic islands typically evolve through large-scale short-term events, either constructing or destructing the volcanic edifice. This tug of war between construction and catastrophic destruction should be recorded within a volcanic island, but old collapse events are sometimes hard to recognize because a number of processes modify the associated structures; therefore, recognition of the testimony of such events onshore, without recourse to offshore high-resolution bathymetry, is challenging and comprises our main objective. Additionally, no large-scale catastrophic sector collapses have ever been reported in the Azores, which makes Santa Maria Island a particularly interesting target. In Santa Maria, lava flows of the two main sub-aerial volcanic complexes dip gently to the west, they are separated by a volcano-sedimentary complex lying on an unconformity dipping gently to the east, and the ages decrease to the east. From this geometry and geochronology, we infer that: (1) more than half of the early shield volcano is missing (absence of all eastern flank, summit and part of the western flank), which we interpret as a large-scale sector collapse whose scar is in part the east-dipping unconformity covered with sediments ca. 4.2 Ma old; (2) the scar was filled by a younger shield volcano that grew very rapidly (ca. 4.0-3.6 Ma); (3) a second large-scale sector collapse followed, which again spared only part of the western flank of the younger shield volcano; (4) new volcanism made of dykes and volcanic cones aligned with the arcuate collapse scar indicate that the slide may have occurred ca. 3.6 Ma ago. We conclude that Santa Maria records onshore evidence of two large-scale sector collapses.

    Despite its many similarities to her better-known novel Belinda, Maria Edgeworth's Angelina is not usually read as a work about lesbianism--even though it begins with the heroine eloping to live with another woman. This article explores same-sex relationships in Angelina and suggests reasons for the work's comparative neglect by lesbian criticism. It examines the process by which the heroine's "unknown friend," the novelist Araminta, moves from being "nobody," a textual construct, to a woman all too thoroughly and grotesquely embodied; and it discusses the role of queer objects, including literary texts, in that process of embodiment.

    Hydropower is the main electricity source of Brazil. The related hydropower reservoirs are multi-purpose thus besides efficient and reliable energy production, they are relevant for flood control. In this context, the present study shows results of an Ensemble Streamflow Prediction (ESP) for supporting the operational decision making implemented at Três Marias hydroelectric power project located in the São Francisco River basin in Brazil. It is a large tropical river basin with approximately 55,000km² up to the Três Marias dam. The hydrological model used in the study is the MGB-IPH (Modelo de Grandes Bacias from Instituto de Pesquisas Hidráulicas), a large scale distributed hydrological model. Applied in an operational forecasting mode, it uses an empirical data assimilation method to take into account real time streamflow observations to update its state variables. We present results of a hindcast experiment with observed precipitation and streamflow data from the local energy utility, CEMIG (Companhia Energética de Minas Gerais), and from the Brazilian water agency, ANA (Agencia Nacional de Água),. Probabilistic Numerical Weather Predictions (NWP) from CPTEC (Centro de Previsão de Tempo e Estudos Climáticos), ECMWF (European Centre for Medium-Range Weather Forecast) and NOAA (National Oceanic and Atmospheric Administration) are used to generate the ESP. The data products and the MGB-IPH model are integrated into an open shell forecasting platform based on the software package Delft-FEWS. Inside the forecasting platform a hindcast mode over a forecast lead time of 10-16 days in recent rainfall periods is applied in. The ESP results are compared to deterministic forecasts of the Três Marias reservoir inflow. The results assessment verifies the added value of the ESP in general in comparison to the use of deterministic forecasts by means of different performance indicators. The ESP derived from the ECMWP ensemble shows the best performance. A future

    The MARIA reactor is open-pool type, water and beryllium moderated. It has two independent primary cooling systems: fuel and pool cooling system. Each fuel assembly is cooled down separately in pressurized channels with individual performances characterization. The fuel assemblies consist of five layers of bent plates or six concentric tubes. Currently it is one of the most powerful research reactors in Europe with operation availability at least up to 2030. Its nominal thermal power is 30 MW. It is characterized by high neutron flux density: up to 3x10{sup 14} n cm{sup -2} s{sup -1} in case of thermal neutrons, and up to 2x10{sup 13} n cm{sup -2} s{sup -1} in case of fast neutrons. The reactor is operated for ca. 4000 h per year. The reactor facility is equipped with fully equipped three hot cells with shielding up to 10{sup 15} Bq. Adjacent to the reactor facility, the radio-pharmaceutics plant (POLATOM) and Material Research Laboratory are located. They are equipped with a number of hot cells with instrumentation. The transport system of radioactive materials from reactor facility to Material Research Laboratory is available. During 2014 the MARIA reactor has been operated with three different types of fuel the same time: previous 36% enriched fuel, and two types of new LEU fuels. In the meantime, molybdenum irradiation programme has been developed. Maria is a multifunctional research tool, with a notable application in production of radioisotopes, radio-pharmaceutics manufacturing (ca. 600 TBq/y), {sup 99}Mo for medical scintigraphy (ca. 6000 TBq/y), neutron transmutation doping of silicon single crystals, wide scientific research based on neutron beams utilization. From the beginning MARIA reactor was intended for loop and fuel testing research activities. Currently it is used mostly as material testing and irradiation facility and for that reason it has wide experimental capabilities. There are eight horizontal irradiation channels from among whom six of them

    Maria Montessori is one of the most well-known women in Italian history. Although she was the first woman who graduated in medicine in Italy, she is mostly known as an educator. Her teaching method--the Montessori Method- is still used worldwide--Because she could not speak English during the imprisonment in India, there was a big obstacle for her communication with children. However, the need to adopt a non-verbal communication, led her to a sensational discovery: children use an innate and universal language. This language, made of gestures and mimic, is called extra verbal communication.

    Boron Neutron Capture Therapy is a very promising form of cancer therapy, consisting in irradiating a stable isotope of boron (10B) concentrated in tumor cells with a low energy neutron beam. This technique makes it possible to destroy tumor cells, leaving healthy tissues practically unaffected. In order to carry out the therapy in the proper way, the proper range of the neutron beam energy has to be chosen. In this paper we present a filter/moderator system modeled with MCNP code in order to obtain an epithermal neutron beam for BNCT post at MARIA reactor in Swierk.

    Paleopositions for southern Baja California peninsula have yielded controversial models over the past 30 years. Mainly based on paleomagnetic data many hypotheses place Baja at lower paleolatitudes in front of southern Mexico or Central America with subsequent northward translations. Other models suggest minor, if any, northward displacements with respect to continental Mexico combined with clockwise rotations. Lithological, geochemical, and geochronological similarities for southern Baja California and Puerto Vallarta (western Mexico Pacific margin) igneous rocks seem to confirm the latter model. To further prove this model we have mapped and collected rocks from Maria Madre, the largest island of the Islas Marias archipelago, located in the mouth of the Gulf of California. In an area of only 145 square kilometers, metamorphic basements rocks (ortho and migmatitic gneisses), highly deformed metasediments, granitoids, acid to intermediate volcanic sequences, and a cover with gently folded marine sediments are exposed. The basement complex with gneisses and metasediments, including garnet-bearing paragneiss and calc silicates, as well as the granodioritic-tonalitic intrusives display an extraordinary accordance with similar units observed in the Los Cabos Block (LCB) of Baja California Sur. Furthermore, U-Pb zircon ages of 162 and 170 Ma for the basement gneisses and of 80 Ma for the granitoids have been reported also from the LCB. Additionally, upper Cretaceous intrusive ages are well known from the Puerto Vallarta batholith in Jalisco and Nayarit, mainland Mexico. Geochemical and isotopic data as well as Nd model ages confirm a magmatic consanguinity of LCB, Islas Marias, and Puerto Vallarta granitoids. The volcanic units of Maria Madre Island include ignimbrites and effusive dacitic-rhyolithic rocks, which can be correlated to the Sierra Madre Occidental province and the Comundú Formation of Baja California. Age determinations are under work to confirm this

  16. A neurophysiologically plausible population code model for feature integration explains visual crowding.

    Directory of Open Access Journals (Sweden)

    Ronald van den Berg

    2010-01-01

    Full Text Available An object in the peripheral visual field is more difficult to recognize when surrounded by other objects. This phenomenon is called "crowding". Crowding places a fundamental constraint on human vision that limits performance on numerous tasks. It has been suggested that crowding results from spatial feature integration necessary for object recognition. However, in the absence of convincing models, this theory has remained controversial. Here, we present a quantitative and physiologically plausible model for spatial integration of orientation signals, based on the principles of population coding. Using simulations, we demonstrate that this model coherently accounts for fundamental properties of crowding, including critical spacing, "compulsory averaging", and a foveal-peripheral anisotropy. Moreover, we show that the model predicts increased responses to correlated visual stimuli. Altogether, these results suggest that crowding has little immediate bearing on object recognition but is a by-product of a general, elementary integration mechanism in early vision aimed at improving signal quality.

  18. Quantum theory as plausible reasoning applied to data obtained by robust experiments.

    Science.gov (United States)

    De Raedt, H; Katsnelson, M I; Michielsen, K

    2016-05-28

    We review recent work that employs the framework of logical inference to establish a bridge between data gathered through experiments and their objective description in terms of human-made concepts. It is shown that logical inference applied to experiments for which the observed events are independent and for which the frequency distribution of these events is robust with respect to small changes of the conditions under which the experiments are carried out yields, without introducing any concept of quantum theory, the quantum theoretical description in terms of the Schrödinger or the Pauli equation, the Stern-Gerlach or Einstein-Podolsky-Rosen-Bohm experiments. The extraordinary descriptive power of quantum theory then follows from the fact that it is plausible reasoning, that is common sense, applied to reproducible and robust experimental data.

  19. Plausible families of compact objects with a Non Local Equation of State

    CERN Document Server

    Hernández, H

    2012-01-01

    We investigate the plausibility of some models emerging from an algorithm devised to generate a one-parameter family of interior solutions for the Einstein equations. It is explored how their physical variables change as the family-parameter varies. The models studied correspond to anisotropic spherical matter configurations having a non local equation of state. This particular type of equation of state with no causality problems provides, at a given point, the radial pressure not only as a function of the density but as a functional of the enclosed matter distribution. We have found that there are several model-independent tendencies as the parameter increases: the equation of state tends to be stiffer and the total mass becomes half of its external radius. Profiting from the concept of cracking of materials in General Relativity, we obtain that those models become more stable as the family parameter increases.

  1. Plausible role of nanoparticle contamination in the synthesis and properties of organic electronic materials

    Science.gov (United States)

    Ananikov, Valentine P.

    2016-12-01

    Traceless transition metal catalysis (Pd, Ni, Cu, etc.) is very difficult to achieve. Metal contamination in the synthesized products is unavoidable and the most important questions are: How to control metal impurities? What amount of metal impurities can be tolerated? What is the influence of metal impurities? In this brief review, the plausible origins of nanoparticle contamination are discussed in the framework of catalytic synthesis of organic electronic materials. Key factors responsible for increasing the probability of contamination are considered from the point of view of catalytic reaction mechanisms. The purity of the catalyst may greatly affect the molecular weight of a polymer, reaction yield, selectivity and several other parameters. Metal contamination in the final polymeric products may induce some changes in the electric conductivity, charge transport properties, photovoltaic performance and other important parameters.

    2016-04-25

    The RNA World hypothesis presupposes that abiotic reactions originally produced nucleotides, the monomers of RNA and universal constituents of metabolism. However, compatible prebiotic reactions for the synthesis of complementary (that is, base pairing) nucleotides and mechanisms for their mutual selection within a complex chemical environment have not been reported. Here we show that two plausible prebiotic heterocycles, melamine and barbituric acid, form glycosidic linkages with ribose and ribose-5-phosphate in water to produce nucleosides and nucleotides in good yields. Even without purification, these nucleotides base pair in aqueous solution to create linear supramolecular assemblies containing thousands of ordered nucleotides. Nucleotide anomerization and supramolecular assemblies favour the biologically relevant β-anomer form of these ribonucleotides, revealing abiotic mechanisms by which nucleotide structure and configuration could have been originally favoured. These findings indicate that nucleotide formation and selection may have been robust processes on the prebiotic Earth, if other nucleobases preceded those of extant life.

  3. Complex adaptive HIV/AIDS risk reduction: Plausible implications from findings in Limpopo Province, South Africa.

    Science.gov (United States)

    Burman, Chris J; Aphane, Marota A

    2016-05-16

    This article emphasises that when working with complex adaptive systems it is possible to stimulate new social practices and/or cognitive perspectives that contribute to risk reduction, associated with reducing aggregate community viral loads. The process of achieving this is highly participatory and is methodologically possible because evidence of 'attractors' that influence the social practices can be identified using qualitative research techniques. Using findings from Limpopo Province, South Africa, we argue that working with 'wellness attractors' and increasing their presence within the HIV/AIDS landscape could influence aggregate community viral loads. While the analysis that is presented is unconventional, it is plausible that this perspective may hold potential to develop a biosocial response - which the Joint United Nations Programme on HIV and AIDS (UNAIDS) has called for - that reinforces the biomedical opportunities that are now available to achieve the ambition of ending AIDS by 2030.

  4. Reciprocity-based reasons for benefiting research participants: most fail, the most plausible is problematic.

    A common reason for giving research participants post-trial access (PTA) to the trial intervention appeals to reciprocity, the principle, stated most generally, that if one person benefits a second, the second should reciprocate: benefit the first in return. Many authors consider it obvious that reciprocity supports PTA. Yet their reciprocity principles differ, with many authors apparently unaware of alternative versions. This article is the first to gather the range of reciprocity principles. It finds that: (1) most are false. (2) The most plausible principle, which is also problematic, applies only when participants experience significant net risks or burdens. (3) Seldom does reciprocity support PTA for participants or give researchers stronger reason to benefit participants than equally needy non-participants. (4) Reciprocity fails to explain the common view that it is bad when participants in a successful trial have benefited from the trial intervention but lack PTA to it.

    Cefazolin was demonstrated to exert high reactivity toward permanganate (Mn(VII)), a common oxidant in water pre-oxidation treatment. In this study, five transformation products were found to be classified into three categories according to the contained characteristic functional groups: three (di-)sulfoxide products, one sulfone product and one di-ketone product. Products analyses showed that two kinds of reactions including oxidation of thioether and the cleavage of unsaturated CC double bond occurred during transformation of cefazolin by Mn(VII). Subsequently, the plausible transformation pathways under different pH conditions were proposed based on the identified products and chemical reaction principles. More importantly, the simulation with real surface water matrix indicated that the proposed transformation pathways of cefazolin could be replayed in real water treatment practices.

    Manuka honey, obtained from Leptospermum scoparium flowers in New Zealand, has strong antibacterial properties. In this study, plausible authentication of the manuka honey was inspected by measuring leptosperin, methyl syringate 4-O-β-D-gentiobiose, along with methyl syringate. Despite a gradual decrease in methyl syringate content over 30 days at 50 °C, even at moderate 37 °C, leptosperin remained stable. A considerable correlation between nonperoxide antibacterial activity and leptosperin content was observed in 20 certified manuka honey samples. Leptosperin and methyl syringate in manuka honey and related products were analyzed using HPLC connected with mass spectrometry. One noncertified brand displayed significant variations in the leptosperin and methyl syringate contents between two samples obtained from different regions. Therefore, certification is clearly required to protect consumers from disguised and/or low-quality honey. Because leptosperin is stable during storage and specific to manuka honey, its measurement may be applicable for manuka honey authentication.

    Following his seminal work in 1953, Stanley Miller conducted an experiment in 1958 to study the polymerization of amino acids under simulated early Earth conditions. In the experiment, Miller sparked a gas mixture of CH4, NH3, and H2O, while intermittently adding the plausible prebiotic condensing reagent cyanamide. For unknown reasons, an analysis of the samples was not reported. We analyzed the archived samples for amino acids, dipeptides, and diketopiperazines by liquid chromatography, ion mobility spectrometry, and mass spectrometry. A dozen amino acids, 10 glycine-containing dipeptides, and 3 glycine-containing diketopiperazines were detected. Miller's experiment was repeated and similar polymerization products were observed. Aqueous heating experiments indicate that Strecker synthesis intermediates play a key role in facilitating polymerization. These results highlight the potential importance of condensing reagents in generating diversity within the prebiotic chemical inventory.

    The number of mutated genes in cancer cells is far larger than the number of mutations that drive cancer. The difficulty this creates for identifying relevant alterations has stimulated the development of various computational approaches to distinguishing drivers from bystanders. We develop and apply an ensemble classifier (EC) machine learning method, which integrates 10 classifiers that are publically available, and apply it to breast and ovarian cancer. In particular we find the following: (1) Using both standard and non-standard metrics, EC almost always outperforms single method classifiers, often by wide margins. (2) Of the 50 highest ranked genes for breast (ovarian) cancer, 34 (30) are associated with other cancers in either the OMIM, CGC or NCG database (P plausible. Biological implications are briefly discussed. Source codes and detailed results are available at http://www.visantnet.org/misi/driver_integration.zip.

    This article presents evidence that the high-nutrient supplement in the Oriente study (Atole) improved child growth. The evidence is presented at 4 levels. There was a causal effect of the intervention on child length, as assessed by probability analyses of the randomized, controlled trial (P < 0.05). The plausibility analyses, which included an examination of wasting, showed that the nutritional impact was due to the Atole, especially in those who were <3 y old and who suffered from diarrhea. The adequacy analyses revealed excellent biological efficacy of the Atole at the individual level. At the level of the whole population, the efficacy of impact was much less, because many children did not participate fully in the supplementation program. The external validity of the biological impact is likely to be good for populations with similar diets and medical care.

    Full Text Available Reptile prime ministers and flying Nazi saucers—extreme and sometimes off-wall conclusion are common ingredients of conspiracy theories. While individual differences are a common research topic concerning conspiracy theories, the role of extreme statements in the process of acquiring and passing on conspiratorial stories has not been regarded in an experimental design so far. We identified six morphological components of conspiracy theories empirically. On the basis of these content categories a set of narrative elements for a 9/11 story was compiled. These elements varied systematically in terms of conspiratorial allegation, i.e., they contained official statements concerning the events of 9/11, statements alleging to a conspiracy limited in time and space as well as extreme statements indicating an all-encompassing cover-up. Using the method of narrative construction, 30 people were given a set of cards with these statements and asked to construct the course of events of 9/11 they deem most plausible. When extreme statements were present in the set, the resulting stories were more conspiratorial; the number of official statements included in the narrative dropped significantly, whereas the self-assessment of the story’s plausibility did not differ between conditions. This indicates that blatant statements in a pool of information foster the synthesis of conspiracy theories on an individual level. By relating these findings to one of Germany’s most successful (and controversial non-fiction books, we refer to the real-world dangers of this effect.

    A primarily analysis of marine geophysical data acquired aboard the RRS James Cook in the framework of the project "Characterization of seismic hazard and tsunami associated with cortical contact structure Rivera Jalisco Block Plate (TSUJAL)" is presented. This survey was held in the region of Nayarit-Tres Marias Islands between February and March 2014. The examination of data recorded by 16 OBS 's, deployed along 4 wide angle seismic profiles is presented, using an airgun-array seismic source of 6800 c.i., which allows sampling the crustal structure to the Moho. The profiles are located along the margin off the Marias Islands: a profile of over 200 km NNW-SSE direction and parallel to the western flank of the Islas Marias Islands and three orthogonal thereto. These perpendicular sections sample the lithosphere from the north of Maria Madre Island with a profile of 100 km length, across Maria Magdalena and Mari Cleofas Islands, with a profile of 50 km long, till south of Maria Cleofas with a profile of 100 km long. Coincident multichannel seismic profiles with refraction ones are also surveyed, although shooting with a source of 3,540 c. i., and acquired with a digital "streamer" of 6.0 km long. Simultaneously, multibeam, parametric and potential field data were recorded during seismic acquisition A first analysis shows an anomalously thickened crust in the western flank of the Marias Islands, as indicated by relatively short pre-critical distances of 30-35 km. While the moderate dip of 7 ° of the subduction of the Pacific oceanic plate favors somehow this effect, the existence of a remnant crustal fragment is also likely. Moreover, the images provided by the parametric sounding show abundant mass wasting deposits suggesting of recent active tectonics, possibly generated by earthquakes with moderate magnitude as those reported in the Marias Islands. This set of geophysical data, not only provide valuable information for the seismogenic characterization and

    Full Text Available The Tres Marias carbonate-hosted Zn-Ge deposit in Chihuahua, Mexico contains willemite [Zn2SiO4] with unusually high concentrations of minor and trace elements (e.g., Pb, Ge, As, P, V; Pb concentrations are as high as 2 wt %, and Ge may reach 4000 ppm (average 900 ppm. Electron microprobe analyses and synchrotron X-ray fluorescence maps show that Zn and Ge, as well as Zn and Pb are negatively correlated, whereas Ge and Pb are positively correlated across zoned willemite crystals. In cathodoluminescence (CL images, those areas of willemite having high trace element concentrations have no, or low CL intensities, whereas zones low in trace elements (except for P display bright blue CL colors. X-ray absorption fine structure (XAFS spectroscopy was used to characterize the chemical nature of Ge and Pb in willemite. Comparisons to reference spectra of natural and artificial substances points to the presence of Ge4+ and Pb2+ in Tres Marias willemite. No evidence for Pb4+ was detected. Oscillatory zonation reflects trace element incorporation into willemite from the oxidation of primary Ge-bearing sphalerite and galena (PbS by siliceous aqueous fluids.

    Full Text Available O artigo analisa alguns livros do pe. Júlio Maria De Lombaerde, missionário belga que veio ao Brasil em 1902 e, desenvolveu parte dos seus trabalhos na cidade de Manhumirim (MG até a sua morte em 1944. O padre Júlio Maria escreveu mais de 80 livros, entre estes livros optou-se em investigar os que tratam do marianismo, da Sagrada Família e da vida de religiosas. A finalidade é refletir sobre os papéis femininos nos quadros da Igreja Católica nas primeiras décadas do século XX, tanto das leigas quanto das religiosas. Para tanto, entende-se que as representações sobre o feminino estavam ancoradas na divisão binária dos gêneros, reforçando hierarquias entre homens e mulheres, bem como na concepção de superioridade do sagrado em relação ao profano, estabelecendo assim, hierarquias, também, entre religiosas e leigas.

    BNCT facility in the Institute of Atomic Energy in Otwock-Swierk is under construction at the horizontal channel H2 of the research reactor MARIA. Measurements of the neutron energy spectrum performed at the front of the H2 experimental channel, have shown that flux of epithermal neutrons (above 10 keV) at the BNCT irradiation port was below 109 n cm-2 s-1 i.e. it was too low to be directly used for the BNCT treatment. Therefore, a fission converter will be placed between the reactor core and the periphery of the graphite reflector of MARIA reactor. The uranium converter will be powered by the densely packed EK-10 fuel elements with 10% enrichment. Preliminary calculations have shown that the total neutron flux in the converter will be about 1013 n cm-2 s-1 and flux of epithermal neutrons at the entrance to the filter/moderator of the beam will be about 2·1013 n cm-2 s-1.

    2009-12-01

    Full Text Available Bianca Maria Visconti duchess of Milan left behind her «a flood of correspondence», composed by either private letters, either dispatches of public interest. Her involvement in public affairs was not limited to the periods of regency, and she could dispose of a group of skilful secretaries (a part of her large household to which she committed the writing of her letters. Her correspondents belonged either to her family − her husband, sons and daugters, relatives, more devote courtiers − either to her impressive patronal network, as ladies-in-waiting, friends, servants, retainers, nobles and aristocrats, prelates and even common people. In particular, the article reconsiders the last correspondence between the duchess and her son Galeazzo Maria, then duke of Milan: these letters reveal a warm personal affection, as much as a deep disagreement about the ruling of public affairs, and fully enlighten the strong temperament of this passionate Renaissance lady. The analysis finally focuses on some comments about the style, the formats, the literary solutions of the letters: for example, the use of autography to establish a closer contact with the correspondent.

    Full Text Available Resumo A ideia de Criança Nova em Maria Montessori (1870-1952 resulta da confluência de duas perspectivas, a da pedagogia que se pretende afirmar como ciência e a do humanismo cristão. Neste artigo, os autores procuram, numa primeira parte, especificar o que vem a ser para a pedagoga italiana a liberdade e a actividade da criança e o papel do adulto, principalmente do educador da criança que se auto-educa e, numa segunda parte, debruçam-se sobre o fundo religioso e humanista da obra montessoriana que consagra a criança como um ser espiritual e de natureza divina. Palavras-chave: actividade; activismo; criança nova; redenção.   Abstract The idea of the New Child in Maria Montesori (1870-1952 is the result of the combination of two perspectives: a pedagogical one, directed at affirming its own scientific status, and one based on Christian Humanism. In this paper the authors try to specify what the Italian pedagogue considered as freedom and activity on the part of the child and the role of the adult, most particularly the role of the educator who also ends up educating himself. At a secondary stage they concentrate on the religious background and the humanism of the Montesorian working method which consecrated the child as a spiritual being who shared the divine nature.

  19. ‘Talk talk talk …’ Virginia Woolf, Ireland and Maria Edgeworth

    Directory of Open Access Journals (Sweden)

    Paul E. H. Davis

    2006-03-01

    Full Text Available This article considers Woolf’s only visit to Ireland and her attitude to the country as revealed in her diary and in a review of a book about Maria Edgeworth. She considered the fault of the Irish to be their loquaciousness. Her diary reveals her belief that Irish literature had declined since Dean Swift. Woolf, both in her twenties and when she visited Ireland in 1934, revealed a certain antipathy to the country. She asserted, for example, that the Irish propensity to talk had prevented the production of literature of any quality after the eighteenth century. In the 1909 review, Woolf, while criticising the author of a book about Maria Edgeworth, attacks Edgeworth herself. But her words imply that she had not read Maria’s Irish novels. Bloomsbury’s ‘snobbery’ and Woolf’s Feminism throughout the essay are evident in her implicit criticism of the way that Edgeworth sacrificed love for duty. In dismissing Edgeworth’s achievement, Woolf betrays a degree of ignorance that is worth considering.

    Full Text Available Abstract OBJECTIVE To analyze the history of the life and activism of Portuguese nurse Maria Augusta Sousa. METHOD Sousa's life story was obtained by means of semi-structured interview swith Sousa as the oral source of data. NVivo qualitative research software was used for data analysis. Content analysis focused on thematic analysis based on the theoretical and philosophical ideas of Michel Foucault, in particular, power and techniques of the self. RESULTS Alienation and political participation were revealed as pertinent issues. In techniques of production of activist subjects, the following were highlighted: the importance of the review of formal education; actions of involvement with the world, society and the profession; and finally, techniques of the self, techniques of constitution of activist subjects, professional identity and way of being. CONCLUSION The constitution of the nurse Maria Augusta Sousa as an activist came about through questioning of how to be, education in the context of her family, and political engagement in Catholic Youth. This impacted her trajectory of contributions to Portuguese nursing, as expressed in the following achievements: the integration of nursing training into higher education; the creation of the Regulation of Nurses Professional Practice; and implementation of the Order of Nurses.

    Islas Marias Archipelago consists of four islands located in the mouth of the Gulf of California. Lithologically three of them (Maria Madre, San Juanito, and Maria Cleofas) are quite similar with a 165-170 Ma metamorphic basement, 75-85 Ma intrusive and extrusive rocks, and a sedimentary sandstone cover, which according to its foraminiferous content recorded multiple uplift and subsidence events related to the opening of the Gulf. However, these units are absent on Maria Magdalena island which is positioned between the other islands. Here, instead, oceanic lithosphere with pillow lavas and gabbroic sills, intercalated with sandstones form the dominant outcrops. Their geochemical and isotopic characteristics are similar to N-MORB with epsilon Nd values around +10 and 87Sr/86Sr of 0.70290. The gabbros are not older than 22 Ma. Magdalena island was obviously uplifted separately from the other islands of the archipelago, probably along a now hidden transform fault system along the East Pacific Rise. Metamorphic and igneous rocks of the other islands can be correlated to lithologically similar units in the Los Cabos Block, Baja California, or to the continental margin units in Sinaloa, Nayarit and Jalisco states when looking at their geochemical and geochronological signatures. Paleomagnetic studies on 35 sampling sites from all 4 islands give evidence for relatively small scale tectonic movements.

    Capturing complete medical knowledge is challenging-often due to incomplete patient Electronic Health Records (EHR), but also because of valuable, tacit medical knowledge hidden away in physicians' experiences. To extend the coverage of incomplete medical knowledge-based systems beyond their deductive closure, and thus enhance their decision-support capabilities, we argue that innovative, multi-strategy reasoning approaches should be applied. In particular, plausible reasoning mechanisms apply patterns from human thought processes, such as generalization, similarity and interpolation, based on attributional, hierarchical, and relational knowledge. Plausible reasoning mechanisms include inductive reasoning, which generalizes the commonalities among the data to induce new rules, and analogical reasoning, which is guided by data similarities to infer new facts. By further leveraging rich, biomedical Semantic Web ontologies to represent medical knowledge, both known and tentative, we increase the accuracy and expressivity of plausible reasoning, and cope with issues such as data heterogeneity, inconsistency and interoperability. In this paper, we present a Semantic Web-based, multi-strategy reasoning approach, which integrates deductive and plausible reasoning and exploits Semantic Web technology to solve complex clinical decision support queries. We evaluated our system using a real-world medical dataset of patients with hepatitis, from which we randomly removed different percentages of data (5%, 10%, 15%, and 20%) to reflect scenarios with increasing amounts of incomplete medical knowledge. To increase the reliability of the results, we generated 5 independent datasets for each percentage of missing values, which resulted in 20 experimental datasets (in addition to the original dataset). The results show that plausibly inferred knowledge extends the coverage of the knowledge base by, on average, 2%, 7%, 12%, and 16% for datasets with, respectively, 5%, 10%, 15%, and

    Residual cardiovascular (CV) risk remains in dyslipidemic patients despite intensive statin therapy, underscoring the need for additional intervention. Eicosapentaenoic acid (EPA), an omega-3 polyunsaturated fatty acid, is incorporated into membrane phospholipids and atherosclerotic plaques and exerts beneficial effects on the pathophysiologic cascade from onset of plaque formation through rupture. Specific salutary actions have been reported relating to endothelial function, oxidative stress, foam cell formation, inflammation, plaque formation/progression, platelet aggregation, thrombus formation, and plaque rupture. EPA also improves atherogenic dyslipidemia characterized by reduction of triglycerides without raising low-density lipoprotein cholesterol. Other beneficial effects of EPA include vasodilation, resulting in blood pressure reductions, as well as improved membrane fluidity. EPA's effects are at least additive to those of statins when given as adjunctive therapy. In this review, we present data supporting the biologic plausibility of EPA as an anti-atherosclerotic agent with potential clinical benefit for prevention of CV events, as well as its cellular effects and molecular mechanisms of action. REDUCE-IT is an ongoing, randomized, controlled study evaluating whether the high-purity ethyl ester of EPA (icosapent ethyl) at 4 g/day combined with statin therapy is superior to statin therapy alone for reducing CV events in high-risk patients with mixed dyslipidemia. The results from this study are expected to clarify the role of EPA as adjunctive therapy to a statin for reduction of residual CV risk.

    The purpose of this review is to provide (1) a synopsis on relations of mindfulness with cardiovascular disease (CVD) and major CVD risk factors, and (2) an initial consensus-based overview of mechanisms and theoretical framework by which mindfulness might influence CVD. Initial evidence, often of limited methodological quality, suggests possible impacts of mindfulness on CVD risk factors including physical activity, smoking, diet, obesity, blood pressure, and diabetes regulation. Plausible mechanisms include (1) improved attention control (e.g., ability to hold attention on experiences related to CVD risk, such as smoking, diet, physical activity, and medication adherence), (2) emotion regulation (e.g., improved stress response, self-efficacy, and skills to manage craving for cigarettes, palatable foods, and sedentary activities), and (3) self-awareness (e.g., self-referential processing and awareness of physical sensations due to CVD risk factors). Understanding mechanisms and theoretical framework should improve etiologic knowledge, providing customized mindfulness intervention targets that could enable greater mindfulness intervention efficacy.

    We present the discovery of a plausible super-luminous supernova (SLSN), found in the archival data of Sloan Digital Sky Survey (SDSS) Stripe 82, called PSN 000123+000504. The supernova peaked at M_g<-21.3 mag in the second half of September 2005, but was missed by the real-time supernova hunt. The observed part of the light curve (17 epochs) showed that the rise to the maximum took over 30 days, while the decline time lasted at least 70 days (observed frame), closely resembling other SLSNe of SN2007bi type. Spectrum of the host galaxy reveals a redshift of z=0.281 and the distance modulus of \\mu=40.77 mag. Combining this information with the SDSS photometry, we found the host galaxy to be an LMC-like irregular dwarf galaxy with the absolute magnitude of M_B=-18.2+/-0.2 mag and the oxygen abundance of 12+log[O/H]=8.3+/-0.2. Our SLSN follows the relation for the most energetic/super-luminous SNe exploding in low-metallicity environments, but we found no clear evidence for SLSNe to explode in low-luminosity ...

    In some theories of sentence comprehension, linguistically relevant lexical knowledge, such as selectional restrictions, is privileged in terms of the time-course of its access and influence. We examined whether event knowledge computed by combining multiple concepts can rapidly influence language understanding even in the absence of selectional restriction violations. Specifically, we investigated whether instruments can combine with actions to influence comprehension of ensuing patients of (as in Rayner, Warren, Juhuasz, & Liversedge, 2004; Warren & McConnell, 2007). Instrument-verb-patient triplets were created in a norming study designed to tap directly into event knowledge. In self-paced reading (Experiment 1), participants were faster to read patient nouns, such as hair, when they were typical of the instrument-action pair (Donna used the shampoo to wash vs. the hose to wash). Experiment 2 showed that these results were not due to direct instrument-patient relations. Experiment 3 replicated Experiment 1 using eyetracking, with effects of event typicality observed in first fixation and gaze durations on the patient noun. This research demonstrates that conceptual event-based expectations are computed and used rapidly and dynamically during on-line language comprehension. We discuss relationships among plausibility and predictability, as well as their implications. We conclude that selectional restrictions may be best considered as event-based conceptual knowledge rather than lexical-grammatical knowledge.

    Glycerol dialkyl glycerol tetraethers (GDGTs) are ubiquitous microbial lipids with extensive demonstrated and potential roles as paleoenvironmental proxies. Despite the great attention they receive, comparatively little is known regarding their diagenetic fate. Putative degradation products of GDGTs, identified as hydroxyl and carboxyl derivatives, were detected in lipid extracts of marine sediment, seep carbonate, hot spring sediment and cells of the marine thaumarchaeon Nitrosopumilus maritimus. The distribution of GDGT degradation products in environmental samples suggests that both biotic and abiotic processes act as sinks for GDGTs. More than a hundred newly recognized degradation products afford a view of the stepwise degradation of GDGT via (1) ether bond hydrolysis yielding hydroxyl isoprenoids, namely, GDGTol (glycerol dialkyl glycerol triether alcohol), GMGD (glycerol monobiphytanyl glycerol diether), GDD (glycerol dibiphytanol diether), GMM (glycerol monobiphytanol monoether) and bpdiol (biphytanic diol); (2) oxidation of isoprenoidal alcohols into corresponding carboxyl derivatives and (3) chain shortening to yield C39 and smaller isoprenoids. This plausible GDGT degradation pathway from glycerol ethers to isoprenoidal fatty acids provides the link to commonly detected head-to-head linked long chain isoprenoidal hydrocarbons in petroleum and sediment samples. The problematic C80 to C82 tetraacids that cause naphthenate deposits in some oil production facilities can be generated from H-shaped glycerol monoalkyl glycerol tetraethers (GMGTs) following the same process, as indicated by the distribution of related derivatives in hydrothermally influenced sediments.

    Chitosan/HI type II salt prepared from crab tendon was investigated by X-ray fiber diffraction. Two polymer chains and 16 iodide ions (I(-)) crystallized in a tetragonal unit cell with lattice parameters of a = b = 10.68(3), c (fiber axis) = 40.77(13) A, and a space group P4(1). Chitosan forms a fourfold helix with a 40.77 A fiber period having a disaccharide as the helical asymmetric unit. One of the O-3... O-5 intramolecular hydrogen bonds at the glycosidic linkage is weakened by interacting with iodide ions, which seems to cause the polymer to take the 4/1-helical symmetry rather than the extended 2/1-helix. The plausible orientations of two O-6 atoms in the helical asymmetric unit were found to be gt and gg. Two chains are running through at the corner and the center of the unit cell along the c-axis. They are linked by hydrogen bonds between N-21 and O-61 atoms. Two out of four independent iodide ions are packed between the corner chains while the other two are packed between the corner and center chains when viewing through the ab-plane. The crystal structure of the salt is stabilized by hydrogen bonds between these iodide ions and N-21, N-22, O-32, O-61, O-62 of the polymer chains.

    4-Aminoimidazole-5-carbonitrile (AICN) was suggested as a prebiotically plausible precursor of purine nucleobases and nucleotides. Although it can be formed in a sequence of photoreactions, AICN is immune to further irradiation with UV-light. We present state-of-the-art multi-reference quantum-chemical calculations of potential energy surface cuts and conical intersection optimizations to explain the molecular mechanisms underlying the photostability of this compound. We have identified the N-H bond stretching and ring-puckering mechanisms that should be responsible for the photochemistry of AICN in the gas phase. We have further considered the photochemistry of AICN-water clusters, while including up to six explicit water molecules. The calculations reveal charge transfer to solvent followed by formation of an H3O(+) cation, both of which occur on the (1)πσ* hypersurface. Interestingly, a second proton transfer to an adjacent water molecule leads to a (1)πσ*/S0 conical intersection. We suggest that this electron-driven proton relay might be characteristic of low-lying (1)πσ* states in chromophore-water clusters. Owing to its nature, this mechanism might also be responsible for the photostability of analogous organic molecules in bulk water.

    A fundamental issue in neuroscience is to understand how neuronal circuits in the cerebral cortex play their functional roles through their characteristic firing activity. Several characteristics of spontaneous and sensory-evoked cortical activity have been reproduced by Infomax learning of neural networks in computational studies. There are, however, still few models of the underlying learning mechanisms that allow cortical circuits to maximize information and produce the characteristics of spontaneous and sensory-evoked cortical activity. In the present article, we derive a biologically plausible learning rule for the maximization of information retained through time in dynamics of simple recurrent neural networks. Applying the derived learning rule in a numerical simulation, we reproduce the characteristics of spontaneous and sensory-evoked cortical activity: cell-assembly-like repeats of precise firing sequences, neuronal avalanches, spontaneous replays of learned firing sequences and orientation selectivity observed in the primary visual cortex. We further discuss the similarity between the derived learning rule and the spike timing-dependent plasticity of cortical neurons.

    The purpose of this review is to examine vitamin D in the context of sport nutrition and its potential role in optimizing athletic performance. Vitamin D receptors (VDR) and vitamin D response elements (VDREs) are located in almost every tissue within the human body including skeletal muscle. The hormonally-active form of vitamin D, 1,25-dihydroxyvitamin D, has been shown to play critical roles in the human body and regulates over 900 gene variants. Based on the literature presented, it is plausible that vitamin D levels above the normal reference range (up to 100 nmol/L) might increase skeletal muscle function, decrease recovery time from training, increase both force and power production, and increase testosterone production, each of which could potentiate athletic performance. Therefore, maintaining higher levels of vitamin D could prove beneficial for athletic performance. Despite this situation, large portions of athletic populations are vitamin D deficient. Currently, the research is inconclusive with regards to the optimal intake of vitamin D, the specific forms of vitamin D one should ingest, and the distinct nutrient-nutrient interactions of vitamin D with vitamin K that affect arterial calcification and hypervitaminosis. Furthermore, it is possible that dosages exceeding the recommendations for vitamin D (i.e. dosages up to 4000-5000 IU/day), in combination with 50 to 1000 mcg/day of vitamin K1 and K2 could aid athletic performance. This review will investigate these topics, and specifically their relevance to athletic performance.

    Recent work in computational neuroscience and cognitive psychology suggests that a set of cells that decay exponentially could be used to support memory for the time at which events took place. Analytically and through simulations on a biophysical model of an individual neuron, we demonstrate that exponentially decaying firing with a range of time constants up to minutes could be implemented using a simple combination of well-known neural mechanisms. In particular, we consider firing supported by calcium-controlled cation current. When the amount of calcium leaving the cell during an interspike interval is larger than the calcium influx during a spike, the overall decay in calcium concentration can be exponential, resulting in exponential decay of the firing rate. The time constant of the decay can be several orders of magnitude larger than the time constant of calcium clearance, and it could be controlled externally via a variety of biologically plausible ways. The ability to flexibly and rapidly control time constants could enable working memory of temporal history to be generalized to other variables in computing spatial and ordinal representations.

    Dual symbioses of vesicular-arbuscular mycorrhizal (VAM) fungi with growth of Momordica charantia were elucidated in terms of plausible mechanism of biosorption in this article. The experiment was conducted in green house and mixed inoculum of the VAM fungi was used in the three replicates. Results demonstrated that the starch contents were the main source of C for the VAM to builds their hyphae. The increased plant height and leaves surface area were explained in relation with an increase in the photosynthetic rates to produce rapid sugar contents for the survival of plants. A decreased in protein, and amino acid contents and increased proline and protease activity in VAM plants suggested that these contents were the main bio-indicators of the plants under biotic stress. The decline in protein may be due to the degradation of these contents, which later on converted into dextrose where it can easily be absorbed by for the period of symbioses. A mechanism of C chemisorption in relation with physiology and morphology of plant was discussed.

    Vitamin D immune-modulating effects were extensively studied, and low levels have been linked with autoimmune diseases. The associations of vitamin D with autoimmune diseases of the liver, and particularly primary biliary cirrhosis (PBC), are yet to be defined. Hence, in this study, serum levels of vitamin D were determined in 79 patients with PBC and 70 age- and sex-matched controls by the LIAISON chemiluminescent immunoassays (DiaSorin-Italy). Clinical and serological parameters of patients were analyzed with respect to vitamin D status. Mean levels of vitamin D were significantly lower among patients with PBC compared with controls (16.8 ± 9 vs. 22.1 ± 9 ng/ml; p = 0.029), and vitamin D deficiency (≤10 ng/ml) was documented in 33% of patients with PBC versus 7% of controls (p plausible roles of vitamin D as a prognostic marker of PBC severity, and as a potential player in this disease pathogenesis. While further studies are awaited, monitoring vitamin D in patients with PBC and use of supplements may be advisable.

  7. Is the de Broglie-Bohm interpretation of quantum mechanics really plausible?

    Science.gov (United States)

    Jung, Kurt

    2013-06-01

    Bohmian mechanics also known as de Broglie-Bohm theory is the most popular alternative approach to quantum mechanics. Whereas the standard interpretation of quantum mechanics is based on the complementarity principle Bohmian mechanics assumes that both particle and wave are concrete physical objects. In 1993 Peter Holland has written an ardent account on the plausibility of the de Broglie-Bohm theory. He proved that it fully reproduces quantum mechanics if the initial particle distribution is consistent with a solution of the Schrödinger equation. Which may be the reasons that Bohmian mechanics has not yet found global acceptance? In this article it will be shown that predicted properties of atoms and molecules are in conflict with experimental findings. Moreover it will be demonstrated that repeatedly published ensembles of trajectories illustrating double slit diffraction processes do not agree with quantum mechanics. The credibility of a theory is undermined when recognizably wrong data presented frequently over years are finally not declared obsolete.

    Full Text Available Agricultural watersheds are affected by changes in climate, land use, agricultural practices, and human demand for energy, food, and water resources. In this context, we analyzed the agricultural, urbanizing Yahara watershed (size: 1345 km², population: 372,000 to assess its responses to multiple changing drivers. We measured recent trends in land use/cover and water quality of the watershed, spatial patterns of 10 ecosystem services, and spatial patterns and nestedness of governance. We developed scenarios for the future of the Yahara watershed by integrating trends and events from the global scenarios literature, perspectives of stakeholders, and models of biophysical drivers and ecosystem services. Four qualitative scenarios were created to explore plausible trajectories to the year 2070 in the watershed's social-ecological system under different regimes: no action on environmental trends, accelerated technological development, strong intervention by government, and shifting values toward sustainability. Quantitative time-series for 2010-2070 were developed for weather and land use/cover during each scenario as inputs to model changes in ecosystem services. Ultimately, our goal is to understand how changes in the social-ecological system of the Yahara watershed, including management of land and water resources, can build or impair resilience to shifting drivers, including climate.

    Combining the temperature and precipitation data from 77 climatological stations and the climatic and hydrological change data from three headstreams of the Tarim River: Hotan, Yarkant, and Aksu in the study area, the plausible association between climate change and the variability of water resources in the Tarim River Basin in recent years was investigated, the long-term trend of the hydrological time series including temperature, precipitation, and streamflow was detected, and the possible association between the El Ni(n)o/Southern Oscillation (ENSO) and these three kinds of time series was tested. The results obtained in this study show that during the past years, the temperature experienced a significant monotonic increase at the speed of 5%, nearly 1℃ rise; the precipitation showed a significant decrease in the 1970s, and a significant increase in the1980s and 1990s, the average annual precipitation was increased with the magnitude of 6.8 mm per decade. A step change occurred in both temperature and precipitation time series around 1986, which may be influenced by the global climate change. Climate change resulted in the increase of the streamflow at the headwater of the Tarim River, but the anthropogenic activities such as over-depletion of the surface water resulted in the decrease of the streamflow at the lower reaches of the Tarim River. The study result also showed that there is no significant association between the ENSO and the temperature, precipitation and streamflow.

    The versatile helicon plasma device, MARIA (Magnetized AnisotRopic Ion-distribution Apparatus), was upgraded with stronger magnetic field B planned as well as design of an ion cyclotron-heating antenna. To quantify the plasma characteristics, diagnostics including a Triple Langmuir Probe, Emissive Probe, and Laser Induced Fluorescence were established. We show first results from characterization of the device. The coupling of the helicon mode in the electron temperature and density parameter space in Argon was mapped out with regard to neutral pressure, B-field and RF power. In addition, validity of the Bohm Criterion and of the Chodura model starting in the weakly collisional regime is tested. A key goal in all efforts is to develop methods of quantitative spectroscopy based on cutting-edge models and active laser spectroscopy.

    The 2009 L'Aquila, Italy earthquake highlighted the seismic vulnerability of historic masonry building structures due to improper "strengthening" retrofit work that has been done in the last 50 years. Italian seismic standards recommend the use of traditional reinforcement techniques such as replacing the original wooden roof structure with new reinforced concrete (RC) or steel elements, inserting RC tie-beams in the masonry and new RC floors, and using RC jacketing on the shear walls. The L'Aquila earthquake revealed the numerous limitations of these interventions, because they led to increased seismic forces (due to greater additional weight) and to deformation incompatibilities of the incorporated elements with the existing masonry walls. This paper provides a discussion of technical issues pertaining to the seismic retrofit of the Santa Maria di Collemaggio Basilica and in particular, the limitations of the last (2000) retrofit intervention. Considerable damage was caused to the church because of questionable actions and incorrect and improper technical choices.

    Full Text Available The Venetian engraver and collector Anton Maria Zanetti, quondam Girolamo the Elder, amused himself by caricaturing well known people of his time, above all operatic singers and other figures from musical theatre at the beginning of the eighteenth century. Zanetti’s graphic satire can be considered the visual equivalent of the famous Teatro alla moda by Benedetto Marcello: there are exact similarities between the biting literary portraits of male and female singers by the aristocratic Venetian composer and the figurative caricatures of castrati and prime donne by Zanetti. The works of both, full of hilarious wit and inveterate prejudices, are part of that satirical movement which accompanied the commercial musical theatre from its beginnings. This critical essay analyses some caricatures of the most famous singers of the time by Zanetti, and appraises the importance of the satirizing of the so-called convenienze teatrali shared by Marcello’s Teatro alla moda.L’incisore e collezionista veneziano Anton Maria Zanetti quondam Girolamo il vecchio si divertì a mettere in caricatura protagonisti del suo tempo, soprattutto cantanti d’opera e altre figure attinenti al teatro musicale del primo Settecento. La satira grafica zanettiana può considerarsi per molti aspetti l’equivalente visivo del celebre Teatro alla moda di Benedetto Marcello: puntuali le corrispondenze tra i graffianti ritratti letterari di virtuosi e canterine dell’aristocratico musicista veneziano e le icastiche caricature di castrati e primedonne di Zanetti. Gli uni e le altre, colmi di arguzie impagabili e inossidabili pregiudizi, rientrano in quel filone satirico che accompagna il teatro d’opera dei circuiti commerciali fin dai suoi esordi. Il saggio prende in considerazione alcune caricature zanettiane dei più noti cantanti dell’epoca, ponendo in valore quella satira delle cosiddette ‘convenienze teatrali’ condivisa dal libello marcelliano.

    Full Text Available The church of Santa Maria in Valle Porclaneta and its accessories are what remains of an ancient Benedictine monastery, built in the heart of Abruzzo region (Magliano dei Marsi, L’Aquila at the end of the XII century. Even if literature, starting from the end of XIX century, has been often interested in this architectural manufactured, the process of historical-critical knowledge of the complex revealed itself difficult due to the absence of archaeological data, the shortage of the documents and, above all, the numerous interventions of restoration that, followed during all last century, have deeply modified the original compages of it. Due to the difficulties met, the overlap between the few documental data and the data derived from the direct investigation of the structures, performed with the aid of an Architectural Informative System, made possible to hypothesize a chronological reconstruction of the principal phases of life of the monastic complex.[it] La chiesa di Santa Maria in Valle Porclaneta e i suoi ambienti accessori sono quanto resta di un antico monastero benedettino, edificato nel cuore del territorio abruzzese (Magliano dei Marsi, L’Aquila sul finire del XII secolo.

Por qué María Zambrano, pues porque nos da dos cosas:1 nos ubica en un tejido hermenéutico que califica de filosófica la cuestión religiosa y, 2 si bien lo religioso como problema tiene su tiempo, Zambrano recupera el tono de actualidad de la relación Dios-persona, vale decir, su pertinencia para la descripción de la impronta del lugar primario de lo religioso en la comunidad humana. Además, que ante la tarea de validar sus objetivos filosóficos, ve en la razón la capacidad de elaborar discursos explicativos sobre la presencia o no de lo sacro en la existencia.This paper has for intention to present sequentially two points associated with the philosophical current importance of the religious thing in a context of a thought as that of Maria Zambrano. Why Maria Zambrano, because she gives us two things: 1 She locates us in a hermeneutical tissue who qualifies of philosophical the religious question and 2 though the religious thing like problem has his time, Zambrano recovers the tone of current importance of the relationship God-person, that is, its pertinence for the description of the stamp of primary place that the religious thing take place in the human community. In addition, that before the task of validating her philosophical aims, she sees in the reason the aptitude to elaborate explanatory speeches about the presence or not of the sacred thing in the existence.

    On January 27, 2013, a fire at the Kiss Nightclub in Santa Maria, Brazil led to a mass-casualty incident affecting hundreds of college students. A total of 234 people died on scene, 145 were hospitalized, and another 623 people received treatment throughout the first week following the incident.1 Eight of the hospitalized people later died.1 The Military Police were the first on scene, followed by the state fire department, and then the municipal Mobile Prehospital Assistance (SAMU) ambulances. The number of victims was not communicated clearly to the various units arriving on scene, leading to insufficient rescue personnel and equipment. Incident command was established on scene, but the rescuers and police were still unable to control the chaos of multiple bystanders attempting to assist in the rescue efforts. The Municipal Sports Center (CDM) was designated as the location for dead bodies, where victim identification and communication with families occurred, as well as forensic evaluation, which determined the primary cause of death to be asphyxia. A command center was established at the Hospital de Caridade Astrogildo de Azevedo (HCAA) in Santa Maria to direct where patients should be admitted, recruit staff, and procure additional supplies, as needed. The victims suffered primarily from smoke inhalation and many required endotracheal intubation and mechanical ventilation. There was a shortage of ventilators; therefore, some had to be borrowed from local hospitals, neighboring cities, and distant areas in the state. A total of 54 patients1 were transferred to hospitals in the capital city of Porto Alegre (Brazil). The main issues with the response to the fire were scene control and communication. Areas for improvement were identified, namely the establishment of a disaster-response plan, as well as regularly scheduled training in disaster preparedness/response. These activities are the first steps to improving mass-casualty responses.

  8. Zinc-germanium ores of the Tres Marias Mine, Chihuahua, Mexico

    The Tres Marias carbonate-hosted Zn-Ge deposit in Chihuahua, Mexico contains sphalerite with the highest average Ge (960 ppm) and willemite with the highest reported Ge contents of Mississippi-Valley-type (MVT) deposits worldwide. This has prompted current exploration efforts to focus on the deposit as a high-grade source of germanium. The sulfide-rich ore type (>125,000 t at 20% Zn and 250 g/t Ge) contains Fe-rich botryoidal sphalerite (type I) associated with solid hydrocarbons. This type exhibits distinctive intimately intergrown lamellar texture of high-Fe sphalerite (average 9.9 wt.% Fe and 800 ppm Ge) and a somewhat less Fe-rich sphalerite phase (average 5.5 wt.% Fe and 470 ppm Ge). Reddish-brown banded sphalerite (type II, average 5.7 wt.% Fe and 1,320 ppm Ge) is subordinately followed by galena and pyrite. The sulfide-poor “oxidized” zinc ore (up to 50 wt.% Zn; 250 to 300 ppm Ge) is a fine-grained, often friable, alteration product of the sulfide ore and associated limestone and breccia host. While some areas are dominated by carbonates and sulfates, others are enriched in silicates such as hemimorphite and willemite. The gangue assemblage includes goethite, hematite, and amorphous silica or quartz. Minor wulfenite, greenockite, cinnabar, and descloizite also occur. Willemite occurs as interstitial replacement of sphalerite and fracture fillings in the oxidized ore and can be unusually rich in Pb (up to 2.0 wt.%) and Ge (up to 4,000 ppm). Oscillatory zonation reflects trace element incorporation into willemite from the oxidation of primary Ge-bearing sphalerite and galena by siliceous aqueous fluids. The Tres Marias deposit has hybrid characteristics consisting of a primary low-temperature MVT Ge-rich Zn-Pb sulfide ore body, overprinted by Ge-rich hemimorphite, willemite, and Fe oxide mineralization.

    Precise computational determination of nuclear heating which consists predominantly of gamma heating (more than 80 %) is one of the challenges in material testing reactor exploitation. Due to sophisticated construction and conditions of experimental programs planned in JHR it became essential to use most accurate and precise gamma heating model. Before the JHR starts to operate, gamma heating evaluation methods need to be developed and qualified in other experimental reactor facilities. This is done inter alia using OSIRIS, MINERVE or EOLE research reactors in France. Furthermore, MARIA - Polish material testing reactor - has been chosen to contribute to the qualification of gamma heating calculation schemes/tools. This reactor has some characteristics close to those of JHR (beryllium usage, fuel element geometry). To evaluate gamma heating in JHR and MARIA reactors, both simulation tools and experimental program have been developed and performed. For gamma heating simulation, new calculation scheme and gamma heating model of MARIA have been carried out using TRIPOLI4 and APOLLO2 codes. Calculation outcome has been verified by comparison to experimental measurements in MARIA reactor. To have more precise calculation results, model of MARIA in TRIPOLI4 has been made using the whole geometry of the core. This has been done for the first time in the history of MARIA reactor and was complex due to cut cone shape of all its elements. Material composition of burnt fuel elements has been implemented from APOLLO2 calculations. An experiment for nuclear heating measurements and calculation verification has been done in September 2014. This involved neutron, photon and nuclear heating measurements at selected locations in MARIA reactor using in particular Rh SPND, Ag SPND, Ionization Chamber (all three from CEA), KAROLINA calorimeter (NCBJ) and Gamma Thermometer (CEA/SCK CEN). Measurements were done in forty points using four channels. Maximal nuclear heating evaluated from

    Full Text Available The forest environments are profoundly altered, mainly due to human action. Specially the alluvial forests, which by its location and ecological function should be preserved and restored, for that it is essential to know the phytosociological and forest structure. The objective of this study was to evaluate the phytosociological parameters and structure of a fragment of Alluvial Deciduous Forest in Santa Maria, RS. For this, we measured 74 contiguous plots of 10 x 10 m (100 m², and considered all individuals with CBH greater than 10 cm. Thus, we identified 32 species, mostly pioneer species, from 19 families. The number of species sampled in the fragment was low, while the dead individuals showed relatively high amount, which is possibly due to human interventions in the area and the process of secondary succession. Some species, such as Casearia sylvestris, Symplocos uniflora, Mimosa bimucronata, Lithrea molleoides and Zanthoxylum rhoifollium stood out with higher rates of phytosociological parameters, with a predominance of the first two. Similarly, analysis of the Expanded Importance Value showed that C. sylvestris and S. uniflora are the most important species of the fragment, as they are more evenly distributed across all vertical strata. = As formações florestais encontram-se alteradas, sobretudo devido à ação antrópica.

    The evidence compiled in the target article demonstrates that the assumptions of cultural group selection (CGS) theory are often met, and it is therefore a useful framework for generating plausible hypotheses. However, more can be said about how we can test the predictions of CGS hypotheses against competing explanations using historical, archaeological, and anthropological data.

  13. Flux-based transport enhancement as a plausible unifying mechanism for auxin transport in meristem development.

    Directory of Open Access Journals (Sweden)

    Szymon Stoma

    2008-10-01

    Full Text Available Plants continuously generate new organs through the activity of populations of stem cells called meristems. The shoot apical meristem initiates leaves, flowers, and lateral meristems in highly ordered, spiralled, or whorled patterns via a process called phyllotaxis. It is commonly accepted that the active transport of the plant hormone auxin plays a major role in this process. Current hypotheses propose that cellular hormone transporters of the PIN family would create local auxin maxima at precise positions, which in turn would lead to organ initiation. To explain how auxin transporters could create hormone fluxes to distinct regions within the plant, different concepts have been proposed. A major hypothesis, canalization, proposes that the auxin transporters act by amplifying and stabilizing existing fluxes, which could be initiated, for example, by local diffusion. This convincingly explains the organised auxin fluxes during vein formation, but for the shoot apical meristem a second hypothesis was proposed, where the hormone would be systematically transported towards the areas with the highest concentrations. This implies the coexistence of two radically different mechanisms for PIN allocation in the membrane, one based on flux sensing and the other on local concentration sensing. Because these patterning processes require the interaction of hundreds of cells, it is impossible to estimate on a purely intuitive basis if a particular scenario is plausible or not. Therefore, computational modelling provides a powerful means to test this type of complex hypothesis. Here, using a dedicated computer simulation tool, we show that a flux-based polarization hypothesis is able to explain auxin transport at the shoot meristem as well, thus providing a unifying concept for the control of auxin distribution in the plant. Further experiments are now required to distinguish between flux-based polarization and other hypotheses.

  14. Identifying and reducing potentially wrong immunoassay results even when plausible and "not-unreasonable".

    The primary role of the clinical laboratory is to report accurate results for diagnosis of disease and management of illnesses. This goal has, to a large extent been achieved for routine biochemical tests, but not for immunoassays which remained susceptible to interference from endogenous immunoglobulin antibodies, causing false, and clinically misleading results. Clinicians regard all abnormal results including false ones as "pathological" necessitating further investigations, or concluding iniquitous diagnosis. Even more seriously, "false-negative" results may wrongly exclude pathology, thus denying patients' necessary treatment. Analytical error rate in immunoassays is relatively high, ranging from 0.4% to 4.0%. Because analytical interference from endogenous antibodies is confined to individuals' sera, it can be inconspicuous, pernicious, sporadic, and insidious because it cannot be detected by internal or external quality assessment procedures. An approach based on Bayesian reasoning can enhance the robustness of clinical validation in highlighting potentially erroneous immunoassay results. When this rational clinical/statistical approach is followed by analytical affirmative follow-up tests, it can help identifying inaccurate and clinically misleading immunoassay data even when they appear plausible and "not-unreasonable." This chapter is largely based on peer reviewed articles associated with and related to this approach. The first section underlines (without mathematical equations) the dominance and misuse of conventional statistics and the underuse of Bayesian paradigm and shows that laboratorians are intuitively (albeit unwittingly) practicing Bayesians. Secondly, because interference from endogenous antibodies is method's dependent (with numerous formats and different reagents), it is almost impossible to accurately assess its incidence in all differently formulated immunoassays and for each analytes/biomarkers. However, reiterating the basic concepts

    We present the discovery of a plausible super-luminous supernova (SLSN), found in the archival data of Sloan Digital Sky Survey (SDSS) Stripe 82, called PSN 000123+000504. The supernova (SN) peaked at m {sub g} < 19.4 mag in the second half of 2005 September, but was missed by the real-time SN hunt. The observed part of the light curve (17 epochs) showed that the rise to the maximum took over 30 days, while the decline time lasted at least 70 days (observed frame), closely resembling other SLSNe of SN 2007bi type. The spectrum of the host galaxy reveals a redshift of z = 0.281 and the distance modulus of μ = 40.77 mag. Combining this information with the SDSS photometry, we found the host galaxy to be an LMC-like irregular dwarf galaxy with an absolute magnitude of M{sub B} = –18.2 ± 0.2 mag and an oxygen abundance of 12+log [O/H]=8.3±0.2; hence, the SN peaked at M {sub g} < –21.3 mag. Our SLSN follows the relation for the most energetic/super-luminous SNe exploding in low-metallicity environments, but we found no clear evidence for SLSNe to explode in low-luminosity (dwarf) galaxies only. The available information on the PSN 000123+000504 light curve suggests the magnetar-powered model as a likely scenario of this event. This SLSN is a new addition to a quickly growing family of super-luminous SNe.

  16. Bio-physically plausible visualization of highly scattering fluorescent neocortical models for in silico experimentation

    2017-02-15

    Background We present a visualization pipeline capable of accurate rendering of highly scattering fluorescent neocortical neuronal models. The pipeline is mainly developed to serve the computational neurobiology community. It allows the scientists to visualize the results of their virtual experiments that are performed in computer simulations, or in silico. The impact of the presented pipeline opens novel avenues for assisting the neuroscientists to build biologically accurate models of the brain. These models result from computer simulations of physical experiments that use fluorescence imaging to understand the structural and functional aspects of the brain. Due to the limited capabilities of the current visualization workflows to handle fluorescent volumetric datasets, we propose a physically-based optical model that can accurately simulate light interaction with fluorescent-tagged scattering media based on the basic principles of geometric optics and Monte Carlo path tracing. We also develop an automated and efficient framework for generating dense fluorescent tissue blocks from a neocortical column model that is composed of approximately 31000 neurons. Results Our pipeline is used to visualize a virtual fluorescent tissue block of 50 μm3 that is reconstructed from the somatosensory cortex of juvenile rat. The fluorescence optical model is qualitatively analyzed and validated against experimental emission spectra of different fluorescent dyes from the Alexa Fluor family. Conclusion We discussed a scientific visualization pipeline for creating images of synthetic neocortical neuronal models that are tagged virtually with fluorescent labels on a physically-plausible basis. The pipeline is applied to analyze and validate simulation data generated from neuroscientific in silico experiments.

    MARIA reactor is an open-pool research reactor what gives the chance to install uranium fission converter on the periphery of the core. It could be installed far enough not to induce reactivity of the core but close enough to produce high flux of fast neutrons. Special design of the converter is now under construction. It is planned to set the research stand based on such uranium converter in the near future: in 2015 MARIA reactor infrastructure should be ready (preparation started in 2013), in 2016 the neutron beam starts and in 2017 opening the stand for material and biological research or for medical training concerning BNCT. Unused for many years, horizontal channel number H2 at MARIA research rector in Poland, is going to be prepared as a part of unique stand. The characteristics of the neutron beam will be significant advantage of the facility. High flux of neutrons at the level of 2x10{sup 9} cm{sup -2}s{sup -1} will be obtainable by uranium neutron converter located 90 cm far from the reactor core fuel elements (still inside reactor core basket between so called core reflectors). Due to reaction of core neutrons with converter U{sub 3}Si{sub 2} material it will produce high flux of fast neutrons. After conversion neutrons will be collimated and moderated in the channel by special set of filters and moderators. At the end of H2 channel i.e. at the entrance to the research room neutron energy will be in the epithermal energy range with neutron intensity at least at the level required for BNCT (2x10{sup 9} cm{sup -2}s{sup -1}). For other purposes density of the neutron flux could be smaller. The possibility to change type and amount of installed filters/moderators which enables getting different properties of the beam (neutron energy spectrum, neutron-gamma ratio and beam profile and shape) is taken into account. H2 channel is located in separate room which is adjacent to two other empty rooms under the preparation for research laboratories (200 m2). It is

    Rain-on-snow events are fascinating but still not completely understood processes. Although, several studies and equations have been published since decades that describe past events and theoretical descriptions, empirical data of what is happening in the snow cover is far less available. A way to fill this gap of empirical data, rain-on-snow-simulators might be of help. In 2013, Juras et al. published their inspiring idea of a portable rain-on-snow simulator. The huge advantage of this devise - in contrast to other purely field-based experiments - are their fixed, and mostly standardized conditions and the possibility to measure all required data to monitor the water fluxes and melting processes at a time. Mounted in a convenient location, a large number of experiments are relatively easy conductible. We applied and further developed the original device and plausified the results of this redesigned version, called RASA. The principal design was borrowed from the original version being a frame with a sprinkler on top and a snow sample in a box at the bottom, from which the outflow is measured with a tipping gauge. We added a moving sprinkling plate to ensure a uniform distribution of raindrops on the snow, and - most importantly - we suspended the watered snow sampled on weighting cells. The latter enables to continuous measurement of the snow sample throughout the experiment and thus the indirect quantification of liquid water saturation, water holding capacity, and snowmelt amount via balance equations. As it is remains unclear if this device is capable to reproduce known processes, a hypothesis based plausibility check was accomplished. Thus, eight hypothesizes were derived from literature and tested in 28 experiments with the RASA mounted at 2000 m elevation. In general, we were able to reproduce most of the hypotheses. The RASA proved to be a very valuable device that can generate suitable results and has the potential to extend the empirical-experimental data

    Human lymphatic filariasis is a parasitic disease with profound socioeconomic encumbrance owing to its associated disability, affecting predominantly but not limited to the developing nations of tropics and subtropics. There are several technical issues like poor therapeutic and preventive repertoire as well as administrative and infrastructural limitations which jeopardize the salvage measures and further complicate the plight. Therefore, considering the gravity of the problem, WHO has mandated (under tropical disease research scheme) for placing emphasis on validation of novel therapeutic targets against this disease with the unfortunate tag of 'neglected tropical disease'. However, dearth of knowledge of parasite biology viciously coupled with difficulty of access to parasitic material from suitable animal model along with growing cost burden of high end research poses formidable challenge. Based on the recent research evidences, here we propose a premise with targeted apoptotic impact as a novel rationale to be exploited towards anti-parasitic drug development. The new era of bioinformatics ushers in new optimism with a wide range of genomic and proteomic database in public domain. Such platform might offer wonders for drug research, but needs highly selective criterion specificity. In order to test our hypothesis presumptively, we deployed a scheme for identification of target proteins from filarial parasitic origin through wide database search with precise criteria of non-homology against the host along with functional essentiality for the parasite. Further screening for proteins with growth potential from such list of essential non-homologous proteins was undertaken to mine out suitable representative target for ensuing apoptotic impact though effective inhibitors. A unique protein enzyme, RNA dependent RNA polymerase, which besides its vital role in RNA virus is believed to have regulatory role in gene expression, emerged as a plausible target. This protein

    Laboratory stress corrosion cracking (SCC) test environments developed to simulate representative BNGS-A steam generator (SG) crevice chemistries have been used to determine the susceptibility of Alloy 600 to lead-induced SCC under plausible SG conditions. Test environments were based on plant SG hideout return data and analysis of removed tubes and deposits. Deviations from the normal near neutral crevice pH environment were considered to simulate possible faulted excursion crevice chemistry and to bound the postulated crevice pH range of 3-9 (at temperature). The effect of lead contamination up to 1000 ppm, but with an emphasis on the 100 to 500 ppm range, was determined. SCC susceptibility was investigated using constant extension rate tensile (CERT) tests and encapsulated C-ring tests. CERT tests were performed at 305 degrees C on tubing representative of BNGS-A SG U-bends. The C-ring test method allowed a wider test matrix covering three temperatures (280, 304 and 315 degrees C), three strain levels (0.2%, 2% and 4%) and tubing representative of U-bends plus tubing given a simulated stress relief to represent material at the tubesheet. The results of this test program confirmed that in the absence of lead contamination, cracking does not occur in these concentrated, 3.3 to 8.9 pH range, crevice environments. Also, it appears that the concentrated crevice environments suppress lead-induced cracking relative to that seen in all-volatile-treatment (AVT) water. For the (static) C-ring tests, lead-induced SCC was only produced in the near-neutral crevice environment and was more severe at 500 ppm than 100 ppm PbO. This trend was also observed in CERT tests but some cracking/grain boundary attack occurred in acidic (pH 3.3) and alkaline (pH 8.9) environments. The C-ring tests indicated that a certain amount of resistance to cracking was imparted by simulated stress relief of the tubing. This heat treatment, confirmed to have resulted in sensitization, promoted

    2015-09-01

    This is an interview with Maria Cecília de Souza Minayo, by university lecturers Iara Coelho Zito Guerriero and Maria Lúcia Magalhães Bosi. It reflects the heat of the current debates surrounding implementation of a specific protocol for evaluation of research in the Human and Social Sciences (HSS), vis-à-vis the current rules set by the National Health Council, which have a clearly biomedical bias. The interview covers the difficulties of introducing appropriate and fair rules for judgment of HSS projects, in the face of a hegemonic understanding of the very concept of science by biologists and medical doctors, who tend not to recognize other approaches unless those approaches adopt their frames of reference. In this case, the National Health Council becomes the arena of this polemic, leading researchers in the human and social sciences to ask themselves whether the health sector has the competency to create rules for other areas of knowledge.

    Due to the lack of studies about neurocysticercosis in the South of Brazil, an investigation was conducted to determine the percentage cases of neurocysticercosis in computed tomography diagnoses in Santa Maria, RS, from January 1997 to December 1998. Of 6300 computed tomographs (CT) of the skull performed at the private Hospital de Caridade Astrogildo de Azevedo, 80, i.e. 1.27% were suspected of neurocysticercosis. Fifty were women (62.5%) and 30 were men (37.5). The most frequent radiological manifestation indicating neurocysticercosis was the presence of calcifications (isolated or associated), with a 95% rate (76 cases), while the presence of hypodense lesions reached a 5% rate (4 cases). After routine analysis, each CT was evaluated again and the suspected cases were confirmed. The percentage of suspected cases of neurocysticercosis detected by CT in the present study carried out in santa Maria was considered low (1.27%). This can be explained by the fact that tomography is not accessible to the economically underprivileged population of Santa Maria. We hope that the present study can alert the population and the professionals to the fact neurocysticercosis is a more frequent disease than indicated by the few diagnoses made. (author)

    We studied basic principles of respiratory physiology in Cylindroleberididae, Cylindroleberis mariae Baird 1850, which are millimetre-sized crustaceans (myodocop ostracod) having a fossil record dating back to about 425 millions years ago. Facing experimental changes of O2 partial pressures in the range 2-40 kPa (normoxia is 21 kPa), C. mariae lack any regulatory mechanism to adapt their ventilatory and circulatory activity. Thus, the oxygenation status of their internal milieu must follow, as a dependent variable, the ambient oxygenation. Freely behaving C. mariae exhibit a marked diurnal activity rhythm. They are actively swimming in the water column during night, where they inspire in normoxic-normocapnic water. They are resting in self-made nests during daytime, where they are rebreathing in a confined and hypoxic environment. By analogy to extensive previous literature data, we suggest that these changes of respiratory gas content, and the associated tissue gas status, participate to the shaping of their metabolic activity and behaviour. To conclude, as Cylindroleberididae are early crustaceans exhibiting a remarkable stasis since the Palaeozoic, present data illustrates how principles of tissue oxygenation strategy can cover an impressive time scale.

    The Payún Matrú Volcanic Field constitutes part of the continental back-arc in Argentina. This volcanic field has been the focus of several regional investigations; however, geochemical analysis of recent volcanoes (<8 ka) at the scale of an individual volcano has not been conducted. We present a morphological description for the Santa Maria Volcano in addition to results from major and trace element analysis and 238U-230Th-226Ra disequilibria. The trace element evidence suggests that the Santa Maria magmatic source has a composition similar to that of the local intraplate end member (resembling an ocean island basalt-like source), with a slight contribution from subduction-related material. The U-series analyses suggest a high 226Ra excess over 230Th for this volcano, which is not derived from a shallow process such as hydrothermal alteration or upper crustal contamination. Furthermore, intermediate-depth processes such as fractional crystallisation have been inferred for the Santa Maria Volcano, but they are not capable of producing the 226Ra excess measured. The 226Ra excess is explained by deep processes like partial melting of mantle lithologies with some influence from subducted Chilean trench sediments. Due to the short half-life of 226Ra (1600 years), we infer that fast magma ascent rates are required to preserve the high 226Ra excess.

    Climate change education programs in the United States seek to promote a deeper understanding of the science of climate change, behavior change and stewardship, and support informed decision making by individuals, organizations, and institutions--all of which are summarized under the term 'climate literacy.' The ultimate goal of climate literacy is to enable actors to address climate change, both in terms of stabilizing and reducing emissions of greenhouse gases, but also an increased capacity to prepare for the consequences and opportunities of climate change. However, the long-term nature of climate change and the required societal response involve the changing students' ideas about controversial scientific issues which presents unique challenges for educators (Lombardi & Sinatra, 2010; Sinatra & Mason, 2008). This session will explore how the United States educational efforts focus on three distinct, but related, areas: the science of climate change, the human-climate interaction, and using climate education to promote informed decision making. Each of these approaches are represented in the Atlas of Science Literacy (American Association for the Advancement of Science, 2007) and in the conceptual framework for science education developed at the National Research Council (NRC) in 2012. Instruction to develop these fundamental thinking skills (e.g., critical evaluation and plausibility reappraisal) has been called for by the Next Generation Science Standards (NGSS) (Achieve, 2013), an innovative and research based way to address climate change education within the decentralized U.S. education system. However, the promise of the NGSS is that students will have more time to build mastery on the subjects, but the form of that instructional practice has been show to be critical. Research has show that effective instructional activities that promote evaluation of evidence improve students' understanding and acceptance toward the scientifically accepted model of human

    Full Text Available Climate risks pose a threat to the function of the global food system and therefore also a hazard to the global financial sector, the stability of governments, and the food security and health of the world’s population. This paper presents a method to assess plausible impacts of an agricultural production shock and potential materiality for global insurers. A hypothetical, near-term, plausible, extreme scenario was developed based upon modules of historical agricultural production shocks, linked under a warm phase El Niño-Southern Oscillation (ENSO meteorological framework. The scenario included teleconnected floods and droughts in disparate agricultural production regions around the world, as well as plausible, extreme biotic shocks. In this scenario, global crop yield declines of 10% for maize, 11% for soy, 7% for wheat and 7% for rice result in quadrupled commodity prices and commodity stock fluctuations, civil unrest, significant negative humanitarian consequences and major financial losses worldwide. This work illustrates a need for the scientific community to partner across sectors and industries towards better-integrated global data, modeling and analytical capacities, to better respond to and prepare for concurrent agricultural failure. Governments, humanitarian organizations and the private sector collectively may recognize significant benefits from more systematic assessment of exposure to agricultural climate risk.

    Full Text Available This paper discusses the lyrics of one of the great names of the contemporary Brazilian poetry, Maria Lúcia Dal Farra, based on the analysis of three poems - Manhã, Culinária and Sustância -, included in Livro de auras (1994, the first literary work published by the author. The objective was to investigate how, in these poems, the daily life is problematized, as a generalizing and repetitive space, characterized by the immediacy and lack of reflection, in favor of a poetry that places this daily life aspect in the female universe and, with an intense meditative tone, reconnects the lost human ties, weaving a mythical time. This encounter dramatizes a poetic attitude that, plunging into experiences considered trivial, makes current the space taken by the affective memory and filled with a sense of belonging and perpetuates it. After the attempt to theoretically comprehend the daily life (Kujawski, 1991; Heller, 1992; Maffesoli, 1998, followed by the poems’ literary analysis, the conclusion reached is that the path that starts at the present day and reaches the essential meaning revelation configures important formal and perspective traits in the figuration of this lyric’s universe.

    Gills of Maria-da-toca Hypleurochilus fissicornis collected at Ponta do Sambaqui-Florianópolis island-Brazil, were analyzed to describe the histopathology caused by metacercaria of Bucephalus margaritae. Gills were submitted to the routine histological techniques for embedding in paraffin and permanent mounting in Balsam and stereoscopic analysis. Metacercariae showed a branchial infection site pattern for encystations. The branchial infection site pattern is half-basalward in the primary branchial filament with amplitude of the infection of 1-3 metacercaria. Cysts occurred within branchial abductor muscle and cartilaginous and osseous tissues of the gills. Each metacercariae had a contentional hyaline parasitic capsule and melanin-like pigmentation. The half-apicalward region of the primary branchial filaments showed several dysplasia degrees, cartilage and osseous degeneration (pyknosis), thrombosis and immune exudated cells (mainly lymphocytes). Cytopathologies as thickening of the epithelium lining of the secondary branchial filaments were a response of the branchial infection site pattern of the metacercaria. Interlamellar obliteration and fusion of the lamellae due to the hypertrophy and hyperplasia of the epithelial lining as well as chloride cells occurred. Pyknosis of pillar cells and epithelial lining cells from the secondary branchial filaments were also present. Bucephalosis in H. fissicornis gills is no-hemorrhagic and no-fatal branchitis, but could compromises the gill functions and could permits the secondary opportunistic infections.

    Full Text Available Most studies on Maria Edgeworth’s oeuvre are centred on her Irish tales. Despite the growing interest in this woman writer, there is no research on her amateur theatricals. After a brief contextualisation of Edgeworth and the stage, this paper aims to describe and highlight the main features of Comic Dramas (1817, one of Edgeworth’s lesser productions. The volume includes three pieces (Love and Law; The Two Guardians and The Rose, Thistle and Shamrock which are set in Ireland and England. Apart from the presence of issues from her tales and educational manuals, what interests us here is that, far from upholding Anglicisation, the Anglo-Irish authoress defends community and an integrating British nation. Comic Dramas is admittedly tinctured by sentimentalism and social critique. For this reason, the examination of these pieces cannot be neglected to obtain a comprehensive panorama of Edgeworth’s vision of Ireland.

    Full Text Available The article discusses the book Rycerz i śmierć written by Katarzyna Kuczyńska-Koschany. The book includes essays on Reiner Maria Rilke’s Duino Elegies published earlier that have been revised and updated. The poem cycle called the Duino Elegies is composed of ten separate poems written in 1912, 1913, 1915 and 1922, i.e. at the peak period of the poet’s imagination and mental activity. The reviewer provides a detailed analysis the first four chapters of the book in which three elegies written before the outbreak of the first war, and the fourth that originated when the war was raging on, are presented. The reviewer appreciates the author’s careful preparation for the book and the ambitious agenda of the author to describe in a synthetic form, for the first time in Poland, the whole cycle of Rilke’s elegies with their Polish translations along with their quality evaluation and comparison taken into consideration, as well as some presentations of German interpretations from prominent specialists in the life and the literary output of Rilke. However, the reviewer is not ready to buy all of the author’s claims and points at numerous, perhaps too numerous, errors, distortions in facts and erroneous reading of the original texts written in German, which, to a high degree, lowers the perceived quality of the discussed book.

  4. The seasonal natural history of the ant, Dolichoderus mariae, in Northern Florida.

    Laskis, Kristina O; Tschinkel, Walter R

    2009-01-01

    Dolichoderus mariae Forel, (Hymenoptera: Formicidae) is an uncommon, monomorphic but locally abundant, reddish-brown ant of peculiar nesting habits, whose range includes most of the eastern USA. In north Florida the ant excavates soil under wiregrass clumps or other plants with fibrous roots to form a single, large, shallow, conical or ovoid chamber broadly open to the surface around the plant base. Colonies are highly polygyne and, during the warm season, inhabit multiple nests connected only by above ground trails, over which nests exchange workers. Although monomorphic, worker size may differ significantly between colonies. The colony cycle is dominated by strong seasonal polydomy. From one or two over-wintering nests, the colonies expanded to occupy up to 60 nests by late summer, then retract once more to one or two nests by mid-winter. The worker-to-queen ratio changed greatly during this cycle, with over two thousand workers per queen during fall and winter, dropping to a low of about 300 during midsummer. Most of these summer queens probably die during the fall. Colonies reoccupy roughly the same area year to year even though they contract down to one or two nests in winter. Observation of fights in the contact zone between colonies suggested that the colonies are territorial. The ants subsist by tending aphids and scale insects for honeydew and scavenging for dead insects within their territories.

  5. [Analytical chemistry in works of Maria Skłodowska-Curie].

    Maria Skłodowska-Curie--a Nobel Prize winner in chemistry--the elements of learning of chemistry gained just by a dint of work of more than ten months in Warsaw in the Institute of Industry and Agriculture Museum. The Nobel Prize concerned a contribution to the progress of chemistry through the discovery of radium and polonium, separation of radium and study of properties of this amazing element. It was awarded for an extremely arduous work, during which the chemical reactions being the principles of analytical chemistry were realized. Unlike to a typical analytical procedure, an initial attempt here was the thousands of kilograms of uranium ore: pitchblende. The final effect was small amounts of new elements: polonium and radium. Both the knowledge and the intuition of the researcher let her have a triumph. The difficulties she experienced because the properties of the searched chemical elements could only be evaluated thanks to the knowledge on other chemical elements. A significant achievement was the determination of the samples by means of radioactivity measurement, which gave rise to radiochemical analytical methods. An extreme analytical precision was demanded in multiple processes of fractional crystallization and precipitation which finally led to the calculation of the atomic mass of radium.

    Full Text Available Le lettere qui esaminate, conservate nella Biblioteca Marucelliana a Firenze, sono scritte da Napoli dal famoso incisore di pietre dure Francesco Maria Gaetano Ghinghi (1689-1762 al celebre erudito e antiquario Anton Francesco Gori. Esse sono ricche di interessanti notizie relative all’attività del Real Laboratorio delle Pietre Dure di Napoli, fondato nel 1737, di cui il Ghinghi fu il primo direttore, e coordinatore dell’équipe di artisti fiorentini che si erano trasferiti con lui. Il Ghinghi fornisce dati sulla circolazione di gemme a Napoli in quel periodo, sulle antichità di Ercolano (di cui il Gori fu uno dei primi a scrivere e sulla permanenza a Napoli di Antonio Pichler, capostipite di una illustre famiglia di incisori, che il Ghinghi conosceva bene, perché entrambi lavoravano per il noto collezionista di gemme Philipp von Stosch. Inoltre, in un quadro di scarsa disponibilità di calchi riproducenti gemme della collezione Farnese, acquista gran valore l’invio di tali impronte da parte del Ghinghi al Gori, che così aveva gemme non documentate altrimenti.

    Full Text Available In questa prima fase della ricerca - ancora in itinere - si compie un’analisi storico-pedagogica del rapporto infanzia/famiglie/istituzioni. L’indagine si focalizza sulle trasformazioni dei modelli familiari, visti nella loro interdipendenza con l’elaborazione di nuove pratiche educative. Al riguardo, l’avvento del’900 si profila come un passaggio importante, che trova un suo esito nel volume di Ellen Key, Il secolo dei fanciulli. Proprio in quest’opera, la scrittrice svedese elabora una nuova idea di “maternità” e di “paternità” che pone al centro i bisogni e le esigenze infantili. La sua prospettiva diventa oggetto di dibattito, agli inizi del secolo scorso, sia in campo pedagogico, sia in campo femminista, soprattutto in merito al dilemma per la donna di coniugare insieme sfera pubblica e sfera privata, maternità e autonomia individuale. Secondo l’ipotesi qui evidenziata è in particolare Maria Montessori a raccogliere la sfida di Ellen Key, con il suo esperimento pedagogico della “Casa dei bambini”, in cui lo spazio domestico, “privato” si trasforma in uno spazio scolastico, “pubblico”, a misura di “bambino” (valenza estetica degli ambienti, cura delle relazioni umane, ecc..

  8. The Sicilian Architect Tommaso Maria Napoli and the Baroque Cathedral of Dubrovnik

    Full Text Available The design of the Dubrovnik Cathedral (1671-1713 – a monumental three-nave basilica with a dome over the crossing – was commissioned, thanks to Abbot Stjepan Gradić, from the Roman architect Andrea Bufalini. Among the leaders of construction, which lasted for over four decades, the Sicilian architect Tommaso Maria Napoli stands out. During his nine-year stay in Dubrovnik (1689-98 he was the only one who engaged in radical changes in the design. Through his changes to the vaulting and lighting of the main nave and sanctuary, as well as the introduction of terraces above the side chapels, he gave the building better proportions, and moreover he balanced its volume by enriching the Cathedral with the plastic expressiveness characteristic of Sicilian architecture at that time. Napoli was the only architect involved in the construction of the Dubrovnik Cathedral who had an international reputation, from his native Sicily, to Naples, Rome, and the Habsburg Monarchy. This makes his inventive corrections to Bufalini's design even more significant.

  9. Literary Fiction or Ancient Astronomical and Meteorological Observations in the Work of Maria Valtorta?

    2017-06-01

    Full Text Available In The Gospel as revealed to me, Maria Valtorta reports a lot of information on the Holy Land at the time of Jesus: historical, archaeological, astronomical, geographical, meteorological. She states she has written what seen “in vision”. By a detailed astronomical analysis of explicit and implicit calendar information reported while she narrates detailed episodes concerning the three years of Jesus’ public life—possible because of many references to lunar phases, constellations, planets visible in the night sky in her writings—it is ascertained that every event described implies a precise date—day, month, year—without being explicitly reported by her. For example, Jesus’ crucifixion should have occurred on Friday April 23 of the year 34, a date proposed by Isaac Newton. She has also recorded the occurrence of rain so that the number of rainy days reported can be compared to the current meteorological data, supposing random observations and no important changes in rainfall daily frequency in the last 2000 years, the latter issue discussed in the paper. Unexpectedly, both the annual and monthly averages of rainy days deduced from the data available from the Israel Meteorological Service and similar averages deduced from her writings agree very well.

  10. A TiO2 abundance map for the northern maria

    A map of TiO2 abundance for most of the northern maria is presented. The telescopic data base used is the 0.38/0.56-micron ratio mosaic from Johnson et at. (1977). The titanium content has been estimated using the correlation established by Charette et al. (1974). The combination of observational, processing, and calibration errors indicates that the TiO2 map is accurate to + or - 2% (wt% TiO2) for high TiO2 content (more than 5%) and + or - 1% for low values of TiO2. Analysis of the lunar sample and telescopic data suggests strongly that the spectral parameter mapped is sensitive primarily to TiO2 abundance in the range 3-9% and does not correlate directly with iron content. It is suggested, however, that for the low TiO2 mare regions (less than 2-3% TiO2) there may be a relation between the spectral ratio and iron content and that some of the reddest mare areas in the Imbrium region may have low iron contents as well as low titanium abundances.

    Full Text Available Introduction: In Brazil, violence against women represents a socialproblem that has been focused in several public health programs, sincethis practice occurs in all social classes. Therefore, based on the fact that women are considered the vulnerable part in a family relationship, the Law number 11.340/2006, known as Maria da Penha law, was approved, enhancing the punishment to those who offend women of their own family. Among the several types of violence against women, those of physical nature are the ones more easily identified by health professionals, including dentists. Objective and case report: This study reports two cases of violence against women with injuries in the head and neck region, in which the first victim was offended with a punch and lost two front teeth (serious injury, while the second victim was also offended with punches that produced orbital and perioral ecchymosis (mild injury that decreased after thirty days. Conclusion: A proper record of the dental procedures performed in violence victims is of great ethical and legal importance, because these dental records may be requested to subsidize both a forensic dental evaluation and a lawsuit against the perpetrator.

    We analyzed data recorded at the Red Sismica Acelerometrica de Jalisco (RESAJ) from November 2010 to August 2013, focus on the seismicity occurred within an area south of the Islas Marias (-105.7, 20.3; -107, 21.8) west of Bahia de Banderas. We observed seismic swarms and low magnitude. Within our data set we identified four seismic swarms episodes. September 14 to 15, 2010 that starts with an earthquake of M = 5.6 at 23:31 followed by approximately 27 events, also has six earthquakes whose magnitudes are between M = 4.0 and M = 5.6; November 11 to December 5, 2011 which contains more than 25 events; October 12 to November 17, 2012 with more than 35 events with an earthquake M = 4.7 occurred on October 29; and finally the swarm occurred between January 20 and February 14, 2013 with over 120 events and one of M = 4.7 occurred on January 22. The last seismic swarm also present activity along two additional areas, one toward the west and the other toward the east of active area previously identified. This seismic activity is associated with the northern edge of the Barra de Navidad Trench whose geometry is unknown. Tectonic structures associated with this seismicity can be tsunamigenic and could represent a danger to nearby populations.

    The biodiversity of the Santa Maria di Leuca (SML) coral bank is summarized and its description is updated using data collected by means of underwater video systems, benthic samplers and fishing gears. A total of 222 living species have been recorded within the coral bank area in the depth range 280-1121 m. The most abundant benthic taxa recorded are Porifera (36 species) followed by Mollusca (35) and Cnidaria (31). The scleractinian corals Madrepora oculata and Lophelia pertusa are the main colonial species in the structure of the SML bank. Annelida, Crustacea and Bryozoa have been found with 24, 23 and 19 species, respectively. A total of 40 species of demersal fish have been recorded. Other faunal taxa were found with small numbers of species. One hundred and thirty-five species are new for the SML bank, 31 of which represent new records for the north-western Ionian Sea (2 Porifera, 17 Cnidaria, 1 Mollusca, 3 Annelida, 2 Crustacea, 4 Bryozoa and 4 Echinodermata). The finding of the annelid Harmothoë vesiculosa represents the first record for the Mediterranean Sea. The SML coral bank represents a biodiversity "hot-spot" on the bathyal bottoms of the Mediterranean Sea.

    2008-03-01

    Full Text Available Con il cambiare dei tempi, sono cambiate anche le priorità nell’ambito sempre più vasto degli animali da compagnia. Se, infatti, fino allo scorso decennio chi si occupava di ortopedia veterinaria aveva a che fare esclusivamente con pazienti traumatizzati, ora l’ortopedia e la traumatologia veterinaria devono fare i conti sempre più spesso con le patologie articolari. I motivi di questa inversione di tendenza sono molti e di diverso genere, certamente i più influenti riguardano la diffusione di soggetti atleti che sviluppano specifiche patologie, l’allungamento della vita media che espone i pazienti a malattie articolari degenerative un tempo prerogativa dell’uomo e la presenza di razze canine particolarmente predisposte a tali patologie. A ciò si aggiunga l’esigenza crescente dei proprietari degli animali, di comprendere a fondo quali siano le migliori cure per i propri compagni. Per questi motivi lo specialista in Ortopedia degli animali domestici, Filippo Maria Martini, ha redatto Patologie articolari nel cane e nel gatto: un volume che non vuole essere un manuale sulle tecniche chirurgiche (nonostante al suo interno vengano comunque descritte, piuttosto un manuale pratico in grado da una parte di fornire gli strumenti necessari per comprendere, interpretare e diagnosticare le patologie articolari; dall’altra di dare le basi teoriche per impostare un protocollo terapeutico in modo corretto ed emettere una prognosi adeguata. Tutto ciò nella convinzione che un buon clinico non possa limitarsi ad eseguire una visita e ad impostare una terapia, ma debba necessariamente stilare un elenco di esami utili ai fini della definizione della diagnosi, discuterne con il proprietario e consigliare il più adeguato protocollo diagnostico e terapeutico.

    Full Text Available ‘Un’altra storia’ (Another History is a first attempt to test the potential of detailed administrative documentation to deepen and, where necessary, modify our understanding of the creative process around the great worksite of Florence Cathedral. It treats two case studies chosen to exemplify possible strategies of navigation in the vast documentary corpus now accessible online in the website, The Years of the Cupola. The first study centers upon the person of Jacopo di Sandro, a hitherto scarcely known master stonecutter employed in the Opera di Santa Maria del Fiore workforce during the entire documented period. He distinguished himself from the very beginning for exceptional flexibility of services rendered, from day labor to a series of special assignments, including the supervision of separate worksites and of the forests in Casentino; Jacopo also emerges as an occasional entrepreneur whose independent contracts coexisted with his status as daily wage earner. At the end of the period he entered the ranks of salaried executive personnel as the administrator of the Brunelleschian fortress of Vico Pisano, demonstrating a notable fluidity amongst labor typologies which are often treated as non-communicating vessels. The second query is dedicated to the documentation on the stone components commissioned for the ‘serraglio’, or closing ring, at the top of the dome, believed to function as stabilizer of the whole self-supporting structure up to the base of the lantern. A census of the sources reveals the number, dimensions, price and delivery dates of the various orders of sandstone blocks, typically supplied in multiples of eight, the number of segments of the octagonal structure. The results are presented as an invitation to look below the surface of the masonry and consider the rationale for so much strength and weight when analyzing the dynamics of this area.

    Full Text Available L’ospedale senese di Santa Maria della Scala si propone alla riflessione europea: per l’imponenza e la ricchezza artistica dell’edificio e per la fortissima identità civica di cui è portatore, dalla sua centralità materiale e simbolica nel tessuto urbano; per l’efficacia delle soluzioni e dell’impianto economico di supporto all’assistenza; per essere stato, dalla fine del Trecento, preso a modello in Italia e in Europa. E, infine, che è quello che più direttamente interessa qui, per la consistenza, varietà e potenzialità del suo patrimonio documentario. Dopo avere illustrato la struttura della documentazione, composta di 6.849 unità (dal 1240 al 1930 e da 5.566 pergamene del fondo diplomatico (dal 1194 al 1725 si richiama l’attenzione sulle potenzialità della documentazione ospedaliera di divenire fonte per la storia della società, dell’economia, delle istituzioni e della politica: tutto ciò attraverso esempi tratti dalla documentazione senese ma pensando che possano servire anche in una prospettiva comparativa più generale. Nel richiamare l’attenzione sul ruolo rivestito dagli ospedali all’interno del sistema sociale, economico e politico sul quale si reggevano le città italiane degli ultimi secoli del Medioevo, e nel dirigere lo sguardo verso l’economia dell’assistenza, Siena può, infatti, dire qualcosa di nuovo, proprio per la particolare ricchezza documentaria e per alcuni caratteri della sua storia e della sua economia.

    Full Text Available En este artículo se analiza la literatura producida por empleadas domésticas, recolectores de basura, prostitutas, niños de la calle, usuarios de drogas, internos de instituciones para menores infractores, presos, todos herederos de la carga que conlleva el difícil acceso a la educación formal. Siendo anteriormente personajes de escritores cultos de clase media, en un determinado momento histórico todos ellos se convierten en autores de sus propias historias. Nuestra hipótesis es que este cambio se dió con Carolina Maria de Jesus, autora del éxito de ventas Quarto de despejo. Sin embargo, al no haber obtenido el mismo éxito con sus otros libros, la autora terminó siendo tratada como un fenómeno aislado. Franco Moretti, crítico mordaz del viejo vicio de preocuparse por singularidades, abre un camino alternativo de análisis con su obra A literatura vista de longe. A partir de Carolina surgió un gran número de autores que necesitan ser estudiados, cuantificados, tabulados con gráficos, mapas y árboles evolutivos, es decir, necesitan ser analizados con las herramientas del crítico italiano. Tomando como punto de partida las ideas de Moretti, el artículo visualiza el desarrollo de este proceso a partir de la aparición de Carolina. La dificultad yace en obtener datos cuantitativos, principal materia prima de Moretti, lo que nos exige una profunda investigación que tiene que empezar tan pronto como sea posible.

    Several regional-scale, fluorescent dye-tracing tests recently showed counter-intuitive, tectonically influenced, preferential ground water flow from the Piora Region via the Santa Maria Valley to the di Campo Valley. Losing rivers of the Piora Valley recharge the Triassic Piora Aquifer at an average rate of 20,000 m3/d and hydrologic budgets suggest that half of the Upper Santa Maria discharge originates from the Piora Region. The geologic map of the Upper Santa Maria Valley presented a partial solution to the hydrogeologic puzzle of the Piora Aquifer, thus facilitating construction of the AlpTransit railway tunnel (the longest on Earth). The autochthonous Lucomagno Triassic of the Gotthard Massif (cargneules), the allochthonous Frodalera-Peiden Triassic (sugar dolomites, para-gneises, quartzites, green phyllites), the Stgir Series of the Lower Jurassic (sandy limestones and quartzites), the Inferno Series of the Middle Jurassic (coarse sandstones, limestones, shales), the Coroi Series of the Upper Jurassic (black shales), the crystalline Gotthard Massif (ortho-gneises), and the northern Penninic Nappe (para- and ortho-gneises, quartzites) are the main lithologies found in the outcrops of the Upper Santa Maria Valley. The highly weathered Triassic series found in the Piora and Upper Santa Maria Valley posed a potential hydrogeologic obstacle that was overcome by tunnel drillers in early 2010, for expected tunnel service by 2012.

    Full Text Available Bianca Maria Visconti duchess of Milan left behind her «a flood of correspondence», composed by either private letters, either dispatches of public interest. Her involvement in public affairs was not limited to the periods of regency, and she could dispose of a group of skilful secretaries (a part of her large household to which she committed the writing of her letters. Her correspondents belonged either to her family − her husband, sons and daugters, relatives, more devote courtiers − either to her impressive patronal network, as ladies-in-waiting, friends, servants, retainers, nobles and aristocrats, prelates and even common people. In particular, the article reconsiders the last correspondence between the duchess and her son Galeazzo Maria, then duke of Milan: these letters reveal a warm personal affection, as much as a deep disagreement about the ruling of public affairs, and fully enlighten the strong temperament of this passionate Renaissance lady. The analysis finally focuses on some comments about the style, the formats, the literary solutions of the letters: for example, the use of autography to establish a closer contact with the correspondent.Bianca Maria Visconti, duchessa di Milano, lasciò una enorme quantità di corrispondenza depositata negli archivi milanesi, sia di carattere privato, sia pubblico e politico. Il suo coinvolgimento negli affari di stato non si limitò ai brevi periodi di reggenza, e grazie a un manipolo di segretari esperti e fedeli, che erano una parte della sua vasta «domus», potè dialogare a distanza con molti interlocutori: membri della sua famiglia e parenti, cortigiani devoti, nobili amici, e con con tutti coloro che facevano parte del suo personale reticolo di protetti e fedeli: dame di corte, servitori, fornitori, ecclesiastici e anche persone umili che si affidavano alla sua protezione.

Os dados fazem parte de uma pesquisa que investigou a rota crítica percorrida pelas mulheres ao decidir denunciar a violência. Os depoimentos foram selecionados de 45 entrevistas semiestruturadas respondidas por 21 mulheres e 25 operadores do setor policial, jurídico, ação social, saúde e organizações não governamentais. Os dados foram analisados com auxílio do software NVivo e um dos temas selecionados foi a Lei Maria da Penha. A maioria dos entrevistados mencionou os aspectos positivos e inovadores da lei, embora tenham apontado também os seus limites. Os operadores percebem o dispositivo legal como recurso importante no enfrentamento às violências, alinhado às convenções internacionais, trazendo inovações e aumentando o acesso das mulheres ao judiciário. Como fragilidades, mulheres e operadores apontaram a ineficiência na aplicação das medidas protetivas, a falta de recursos materiais e de pessoas, a fragmentação da rede de atenção e o movimento de setores conservadores da sociedade para deslegitimar a Lei.This paper presents the declarations about the Maria da Penha law made by a sample of women victims and care workers who handle situations of gender violence in the city of Porto Alegre.

    Full Text Available O artigo analisa a trajetória da belga Maria Rennotte que em 1878 mudou-se para o Brasil, onde trabalhou como preceptora, professora e médica. Com seus escritos e sua prática social, Maria Rennotte lutou pelos direitos das mulheres a uma melhor educação, ao acesso a diferentes tipos de trabalho, à obtenção de um corpo mais saudável, à cidadania política. Pregou a participação das mulheres em entidades assistenciais, e fundou uma filial da Cruz Vermelha na capital paulista. A análise de sua trajetória possibilita afirmar que apesar de desconsideradas politicamente, não terem reconhecidos os direitos civis, possuírem limitadas oportunidades educacionais e de trabalho remunerado e serem identificadas basicamente como mães e esposas, pela atuação nas associações filantrópicas as mulheres participaram efetivamente da vida nacional, deixando sua marca nos serviços prestados à população, nas leis, na organização de instituições de ensino e de saúde e no desenvolvimento do conhecimento científico.The article analyses the trajectory of Maria Rennotte, a Belgian who in 1878 moved to Brazil working as a governess, and afterwards as a teacher and doctor. With her writings and social practice, Maria Rennotte fought for women's rights in search for better education, access to different types of work, a healthier body and political citizenship. She asserted women's participation in assistance entities, founding a Red Cross branch in São Paulo. Her trajectory enables us to state that although women were not politically considered in terms of their civil rights, had limited educational opportunities and few chances of wage-earning jobs, basically being identified as mothers and wives, they found in philanthropic associations a breach to enlarge their participation in the public sphere. Acting in national life, women changed the services offered to the people, the law, the educational and health institutions and the development

    Full Text Available In the light of some recent hypotheses suggesting plausible unification of thermostatistics where Fermi-Dirac, Bose-Einstein and Tsallis statistics become its special subsets, we consider further plausible extension to include non-integer Hausdorff dimension, which becomes realization of fractal entropy concept. In the subsequent section, we also discuss plausible extension of this unified statistics to include anisotropic effect by using quaternion oscillator, which may be observed in the context of Cosmic Microwave Background Radiation. Further observation is of course recommended in order to refute or verify this proposition.

    This article shows the results obtained in the three dimensional survey of the church of Santa Maria of Castrelos realized through a terrestrial Laser Scanner. The Church of Santa Maria of Castrelos, which was built in the early thirteenth century, is located in Vigo Spain. It is a Romanesque style church with a nave and semicircular apse with three gates decorated with rosettes and typically Romanesque geometrical figures. The survey was conducted by the laboratory of Close Range Photogrammetry of Natural Resources Department, Mining School, at University of Vigo - Spain, jointly with the Geomatics Department, Federal University of Parana - Brazil. This work explores the use of laser scanning for the surveying, three-dimensional modeling and documentation of historical monuments but also the generation of quoted plans and cross sections of this Romanesque church in the city of Vigo. The resolution of point clouds used to obtain the models varied according to need. Namely, the point cloud used for three-dimensional model for the general external and internal church was used with an approximate step width of 10 cm, while 5 cm and 1 cm step widths were used for details of geometric figures and rosettes. The results of both the three-dimensional model and the plans and sections are in accordance with the specifications and scales of representation usually used in conventional surveys of historic monuments recommended in the specialized literature in the area. The objective of this study is showing the potential of the use of terrestrial laser scanner in the documentation of historical heritage through achieving the 3D model by joining external and internal point clouds and the generation of planes and sections of the church of Santa Maria of Castrelos, Vigo.

    In this study, five ionic liquids (ILs) have been explored for biomass pretreatment for the production of fermentable sugar. We also investigated the driving factors responsible for improved enzymatic digestibility of various ILs treated biomass along with postulating the plausible mechanism thereof. Post pretreatment, mainly two factors impacted the enzymatic digestibility (i) structural deformation (cellulose I to II) along with xylan/lignin removal and (ii) properties of ILs; wherein, K-T parameters, viscosity and surface tension had a direct influence on pretreatment. A systematic investigation of these parameters and their impact on enzymatic digestibility is drawn. [C2mim][OAc] with β-value 1.32 resulted 97.7% of glucose yield using 10 FPU/g of biomass. A closer insight into the cellulose structural transformation has prompted a plausible mechanism explaining the better digestibility. The impact of these parameters on the digestibility can pave the way to customize the process to make biomass vulnerable to enzymatic attack.

    2014-10-25

    Electronic drug application records from farmers from 75 conventional pig farms were revised and checked for their plausibility. The registered drug amounts were verified by comparing the farmers' records with veterinarians' dispensary records. The antimicrobial consumption was evaluated from 2008 to 2011 and expressed in weight of active substance(s), number of used daily doses (nUDD), number of animal daily doses (nADD) and number of product-related daily doses (nPrDD). All results were referred to one year and animal bodyweight (kg biomass). The data plausibility proof revealed about 14 per cent of unrealistic drug amount entries in the farmers' records. The annual antimicrobial consumption was 33.9 mg/kg/year, 4.9 UDDkg/kg/year, 1.9 ADDkg/kg/year and 2.5 PrDDkg/kg/year (average). Most of the antimicrobials were applied orally (86 per cent) and at group-level. Main therapy indications were metaphylactic/prophylactic measures (farrow-to-finish and fattening farms) or digestive tract diseases (breeding farms). The proportion of the 'highest priority critically important antimicrobials' was low (12 per cent). After determination of a threshold value, farms with a high antimicrobial use could be detected. Statistical tests showed that the veterinarian had an influence on the dosage, the therapy indication and the active substance. Orally administered antimicrobials were mostly underdosed, parenterally administered antimicrobials rather correctly or overdosed.

    In 2012 a manuscript was rediscovered in the Biblioteca dell'Archiginnasio of Bologna, titled Libro degli infermi dell'Arciconfraternita di S. Maria della Morte. It is the record of incoming patients of one for the main hospitals of the city, devoted exclusively to the sick poor and not just to the poor, called Santa Maria della Morte, compiled by a young student assistant (astante) for the period 1558-1564. I publish here a transcription of a portion of this Libro pertaining to the year 1560. My introduction situates the manuscript within the context of the history of early modern Italian hospitals, describes the organization of the hospital of Santa Maria della Morte based on archival sources of the period, and finally highlights the connections between surgical and anatomical education and the internal organization of the hospital.

    Lupinus mariae-josephi is a recently described endemic Lupinus species from a small area in Eastern Spain where it thrives in soils with active lime and high pH. The L. mariae-josephi root symbionts were shown to be very slow-growing bacteria with different phenotypic and symbiotic characteristics from those of Bradyrhizobium strains nodulating other Lupinus. Their phylogenetic status was examined by multilocus sequence analyses of four housekeeping genes (16S rRNA, glnII, recA, and atpD) and showed the existence of a distinct evolutionary lineage for L. mariae-josephi that also included Bradyrhizobium jicamae. Within this lineage, the tested isolates clustered in three different sub-groups that might correspond to novel sister Bradyrhizobium species. These core gene analyses consistently showed that all the endosymbiotic bacteria isolated from other Lupinus species of the Iberian Peninsula were related to strains of the B. canariense or B. japonicum lineages and were separate from the L. mariae-josephi isolates. Phylogenetic analysis based on nodC symbiotic gene sequences showed that L. mariae-josephi bacteria also constituted a new symbiotic lineage distant from those previously defined in the genus Bradyrhizobium. In contrast, the nodC genes of isolates from other Lupinus spp. from the Iberian Peninsula were again clearly related to the B. canariense and B. japonicum bv. genistearum lineages. Speciation of L. mariae-josephi bradyrhizobia may result from the colonization of a singular habitat by their unique legume host. Copyright © 2011 Elsevier GmbH. All rights reserved.

    Full Text Available This study focused on the determination of the delivery of services of day care workers in the municipality of Sta. Maria, Province of Laguna during the first semester of school year 2012-2013. Descriptive research was used in this study. Among the key findings were that Day Care Workers with respect to interactional relationship accomplished the functions with outstanding adequacy such as constantly giving feedback and praises on the performance of children, along with workers and parents coordination and cooperation, with verbal interpretation of Always Observe. In terms of instructional quality both group of respondents perceived that day care workers in-charge had adequate abilities and competencies concerning their education and trainings in connection with teaching small children with verbal interpretation of Always Observe. The parents had confidence to the day care workers in-charge of their children aside from regularly consulting the day care workers about their children’s progress with verbal interpretation of Always Observe. There were only 871 households who availed of the services of day care centers in which 27 workers were employed and each of them assigned to handle an average of 33 children. Notable along with other findings was the day care workers and parents had the same perception as to the extent of services provided by the Day Care Center with respect to interactional relationship, instructional quality and parental participation. Subsequently the study ensued with these five factual remarks: Children’s interactions with parents in the centers were the direct mechanisms through which children learn. The educational qualification and the capability of the day care workers to handle small children were the primary essentials in children’s learning. Parents’ participation in the day care centers premises brought harmonious relationship between the Day Care Workers and children as well. The capacity of day care worker

    The southern region of Islas Marias, in front of Bahía de Banderas (21.20,-106.80; 20.26, -106.05), is characterized by a low magnitude seismicity as recorded in both international and national catalogues. However due to the lack of coverage by the seismic stations in the region only a few records exist. It is assumed that the seismicity results from the subduction effect of the Rivera Plate with the Jalisco Block. The Accelerometric Seismic Network of Jalisco (RESAJ) has recorded the events of September 14th 2012 Mw=5.6 and the event of the first of the month Mw=4.9 and 27 more events. Because of this evidence, along with the history of the earthquake of M=7.0 on December third 1948 in Islas Marias, which almost destroyed the penal colony, it is important to study the seismicity of the area given the potential risk that this represent for the populations nearby. The RESAJ data also includes three groups of earthquakes detected in last months of December and November 2012, and the earthquake on Wednesday January 23th 2013, along with their characteristic group. Here, we present the first part of a study of the seismicity of the area using the RESAJ records. By analyzing the aforementioned data it is shown that seismicity of the zone occurs by clusters.

    2014-12-01

    Previous studies have combined climate, crop and economic models to examine the impact of climate change on agricultural production and food security, but results have varied widely due to differences in models, scenarios and data. Recent work has examined (and narrowed) these differences through systematic model intercomparison using a high-emissions pathway to highlight the differences. New work extends that analysis to cover a range of plausible socioeconomic scenarios and emission pathways. Results from three general circulation models are combined with one crop model and five global economic models to examine the global and regional impacts of climate change on yields, area, production, prices and trade for coarse grains, rice, wheat, oilseeds and sugar to 2050. Results show that yield impacts vary with changes in population, income and technology as well as emissions, but are reduced in all cases by endogenous changes in prices and other variables.

  6. Gene-ontology enrichment analysis in two independent family-based samples highlights biologically plausible processes for autism spectrum disorders.

    2012-02-01

    Recent genome-wide association studies (GWAS) have implicated a range of genes from discrete biological pathways in the aetiology of autism. However, despite the strong influence of genetic factors, association studies have yet to identify statistically robust, replicated major effect genes or SNPs. We apply the principle of the SNP ratio test methodology described by O\\'Dushlaine et al to over 2100 families from the Autism Genome Project (AGP). Using a two-stage design we examine association enrichment in 5955 unique gene-ontology classifications across four groupings based on two phenotypic and two ancestral classifications. Based on estimates from simulation we identify excess of association enrichment across all analyses. We observe enrichment in association for sets of genes involved in diverse biological processes, including pyruvate metabolism, transcription factor activation, cell-signalling and cell-cycle regulation. Both genes and processes that show enrichment have previously been examined in autistic disorders and offer biologically plausibility to these findings.

    2015-10-01

    Childhood adversity, characterized by abuse, neglect, and household dysfunction, is a problem that exerts a significant impact on individuals, families, and society. Growing evidence suggests that adverse childhood experiences (ACEs) are associated with health decline in adulthood, including cardiovascular disease (CVD). In the current review, we first provide an overview of the association between ACEs and CVD risk, with updates on the latest epidemiological evidence. Second, we briefly review plausible pathways by which ACEs could influence CVD risk, including traditional risk factors and novel mechanisms. Finally, we highlight the potential implications of ACEs in clinical and public health. Information gleaned from this review should help physicians and researchers in better understanding potential long-term consequences of ACEs and considering adapting current strategies in treatment or intervention for patients with ACEs.

    A 16-year-old male presented to hospital following an episode of unusual behavior on the football pitch, where he was witnessed as grossly ataxic by his teammates. The assessment demonstrated marked cerebellar signs on examination but no other neurological deficit. The investigation showed the evidence of biochemical thyrotoxicosis with free T4 at 37 pmol/L (normal reference range: 11-27) and thyrotropin (TSH) plausible because alternative etiologies were excluded, and the normalization of thyroid function with treatment was coupled with complete resolution of the neurological syndrome. Cerebellar syndromes may well be one of the presenting features of thyrotoxicosis, and this should be in the list of its differential diagnosis.

    Full Text Available The aqueous environment is a pervasive factor which, in many ways, determines the protein folding process and consequently the activity of proteins. Proteins are unable to perform their function unless immersed in water (membrane proteins excluded from this statement. Tertiary conformational stabilization is dependent on the presence of internal force fields (nonbonding interactions between atoms, as well as an external force field generated by water. The hitherto the unknown structuralization of water as the aqueous environment may be elucidated by analyzing its effects on protein structure and function. Our study is based on the fuzzy oil drop model—a mechanism which describes the formation of a hydrophobic core and attempts to explain the emergence of amyloid-like fibrils. A set of proteins which vary with respect to their fuzzy oil drop status (including titin, transthyretin and a prion protein have been selected for in-depth analysis to suggest the plausible mechanism of amyloidogenesis.

  10. Charting plausible futures for diabetes prevalence in the United States: a role for system dynamics simulation modeling.

    Healthy People 2010 (HP 2010) objectives call for a 38% reduction in the prevalence of diagnosed diabetes mellitus, type 1 and type 2, by the year 2010. The process for setting this objective, however, did not focus on the achievability or the compatibility of this objective with other national public health objectives. We used a dynamic simulation model to explore plausible trajectories for diabetes prevalence in the wake of rising levels of obesity in the U.S. population. The model helps to interpret historic trends in diabetes prevalence in the United States and to anticipate plausible future trends through 2010. We conducted simulation experiments using a computer model of diabetes population dynamics to 1) track the rates at which people develop diabetes, are diagnosed with the disease, and die, and 2) assess the effects of various preventive-care interventions. System dynamics modeling methodology based on data from multiple sources guided the analyses. With the number of new cases of diabetes being much greater than the number of deaths among those with the disease, the prevalence of diagnosed diabetes in the United States is likely to continue to increase. Even a 29% reduction in the number of new cases (the HP 2010 objective) would only slow the growth, not reverse it. Increased diabetes detection rates or decreased mortality rates--also HP 2010 objectives--would further increase diagnosed prevalence. The HP 2010 objective for reducing diabetes prevalence is unattainable given the historical processes that are affecting incidence, diagnosis, and mortality, and even a zero-growth future is unlikely. System dynamics modeling shows why interventions to protect against chronic diseases have only gradual effects on their diagnosed prevalence.

    Bacterial strains isolated from nitrogen-fixing nodules of Lupinus mariae-josephae have been characterized following genetic, phenotypic and symbiotic approaches. Analysis of 16S rRNA genes placed them in a group together with Bradyrhizobium elkanii USDA 76(T), B. pachyrhizi PAC48(T), B. jicamae PAC68(T), 'B. retamae' Ro19(T) and B. lablabi CCBAU 23086(T) with over 99.0% identity. Phylogenetic analysis of concatenated housekeeping genes, recA, atpD and glnII, suggested that L. mariae-josephae strains represent a new Bradyrhizobium species, closely related to B. lablabi CCBAU 23086(T), B. jicamae PAC68(T) and 'B. retamae' Ro19(T) with 92.1, 91.9 and 90.8% identity, respectively. These results are consistent with overall genomic identities calculated as Average Nucleotide Identity (ANIm) using draft genomic sequences obtained for relevant strains. While L. mariae-josephae strains LmjM3(T)/LmjM6 exhibited a 99.2% ANIm value, they were significantly distant (lupine species. Based on genetic, genomic, proteomic and phenotypic data presented in this study, L. mariae-josephae nodulating strains LmjM3(T), LmjM6 and LmjM2 should be grouped within a new species for which the name Bradyrhizobium valentinum sp. nov. is proposed (type strain LmjM3(T)=CECT 8364(T), LMG 2761(T)).

    1988-01-01

    Foraminifera and diatoms have been analyzed from an upper Miocene through Pleistocene(?) sequence of marine sediments exposed on Maria Madre Island, largest of the Tre??s Marias Islands off the Pacific coast of Mexico. The Neogene stratigraphic sequence exposed on Maria Madre Island includes a mid-Miocene(?) non-marine and/or shallow marine sandstone unconformably overlain by a lower upper Miocene to uppermost Miocene upper to middle bathyal laminated and massive diatomite, mudstone, and siltstone unit. This unit is unconformably overlain by lower Pliocene middle to lower bathyal sandstones and siltstones which, in turn, are unconformably overlain by upper Pliocene through Pleistocene(?) upper bathyal to upper middle bathyal foraminiferal limestones and siltstones. These beds are unconformably capped by Pleistocene terrace deposits. Basement rocks on the island include Cretaceous granite and granodiorite, and Tertiary(?) andesites and rhyolites. The upper Miocene diatomaceous unit contains a low diversity foraminiferal fauna dominated by species of Bolivina indicating low oxygen conditions in the proto-Gulf Maria Madre basin. The diatomaceous unit grades into a mudstone that contains a latest Miocene upper to middle bathyal biofacies characterized by Baggina californica and Uvigerina hootsi along with displaced neritic taxa. An angular unconformity separates the upper Miocene middle bathyal sediments from overlying lower Pliocene siltstones and mudstones that contain a middle to lower bathyal biofacies and abundant planktonic species including Neogloboquadrina acostaensis and Pulleniatina primalis indicating an early Pliocene age. Significantly, this Pliocene unit contains common occurrences of benthic species restricted to Miocene sediments in California including Bulimina uvigerinaformis. Pliocene to Pleistocene(?) foraminiferal limestones and siltstones characterize submarine bank accumulations formed during uplift of the Tre??s Marias Island area, and include

    Full Text Available Il volume intende mettere in luce il valore attuale delle teorie e pratiche educativo-pedagogiche proposte da Maria Edgeworth. Agli albori della scienza moderna, Edgeworth si muove in un milieu assolutamente stimolante, che raccoglie alcuni tra i più grandi pensatori dell’epoca in ambito filosofico, educativo e culturale. La loro influenza, anche e soprattutto attraverso il lavoro costantemente sviluppato col padre, la porterà in pochi anni a formulare teorie educative che troveranno subito ampio riscontro presso la comunità intellettuale. La grande novità del suo progetto risiede nell’elaborazione di un sistema pedagogico coerente, basato su testi teorici e pratici ideati e composti in un linguaggio specifico di matrice scientifica ma con intento divulgativo, per l’educazione del bambino fino all’età della maturità. Pur mettendo in luce i limiti storici di alcuni presupposti del pensiero edgeworthiano, appare importante sottolineare l’attualità e l’attuabilità della sua proposta metodologica, fondata su indagini circostanziate e documentate secondo criteri oggi considerati basilari per la corretta attuazione della pratica educativa, che deve coinvolgere fattivamente il bambino e l’adulto. Maria Edgeworth supera la letteratura, quindi, per rivelarsi un assistant scientifico allo sviluppo dell’individuo in una società civile, moderna e in continua evoluzione.Profilo biograficoRaffaella Leproni è ricercatore di Lingua e traduzione inglese presso il Dipartimento di Scienze della Formazione dell’Università degli Studi Roma Tre, dove svolge didattica in diversi Corsi di Studio utilizzando materiali autentici di matrice socio-pedagogica ed educativa in prospettiva CLIL; collabora sul tema ad un progetto sperimentale con la Pädagogische Hochschule di Salisburgo.

    The Hosgri Fault Zone trends subparallel to the south-central California coast for 110 km from north of Point Estero to south of Purisima Point and forms the eastern margin of the present offshore Santa Maria Basin. Knowledge of the attributes of the Hosgri Fault Zone is important for petroleum development, seismic engineering, and environmental planning in the region. Because it lies offshore along its entire reach, our characterizations of the Hosgri Fault Zone and adjacent structures are primarily based on the analysis of over 10,000 km of common-depth-point marine seismic reflection data collected from a 5,000-km2 area of the central and eastern parts of the offshore Santa Maria Basin. We describe and illustrate the along-strike and downdip geometry of the Hosgri Fault Zone over its entire length and provide examples of interpreted seismic reflection records and a map of the structural trends of the fault zone and adjacent structures in the eastern offshore Santa Maria Basin. The seismic data are integrated with offshore well and seafloor geologic data to describe the age and seismic appearance of offshore geologic units and marker horizons. We develop a basin-wide seismic velocity model for depth conversions and map three major unconformities along the eastern offshore Santa Maria Basin. Accompanying plates include maps that are also presented as figures in the report. Appendix A provides microfossil data from selected wells and appendix B includes uninterpreted copies of the annotated seismic record sections illustrated in the chapter. Features of the Hosgri Fault Zone documented in this investigation are suggestive of both lateral and reverse slip. Characteristics indicative of lateral slip include (1) the linear to curvilinear character of the mapped trace of the fault zone, (2) changes in structural trend along and across the fault zone that diminish in magnitude toward the ends of the fault zone, (3) localized compressional and extensional structures

    Monazite-(Ce) is found in granitic pegmatites in the Santa Maria de Itabira pegmatite district (Minas Gerais, Brazil). During the magmatic stage, monazite-(Ce) seems to have had higher contents of cheralite and buttonite in the solid solution. The Th content in primary monazite-(Ce) is high and characteristic for each pegmatite body. During the late stage (albitisation), the mean LREE content in the altered zone is slightly higher and Th content is very low. The accessory mineral assemblages changed; buttonite and cheralite crystallize together with Th-poor and La-rich monazite-(Ce) at the border of altered crystals. Nd/Sm and U/Pb ratios also changed during the hydrothermal stage. (authors) 13 refs.

  7. The Santa Barbara Channel - Santa Maria Basin Study: Wind Measurements and Modeling Resolving Coastal Mesoscale Meteorology

    2002-12-01

    The importance of winds in driving the coastal ocean has long been recognized. Pre-World War II literature links wind stress and wind stress curl to coastal ocean responses. Nevertheless, direct measurements plausibly representative of a coastal area are few. Multiple observations on the scale of the simplest mesoscale atmospheric structure, such as the cross-coast variation along a linear coast, are even less frequent. The only wind measurements that we are aware of in a complicated coastal area backed by higher topography are in the MMS sponsored, Santa Barbara Channel/Santa Marina basin study. Taking place from 1994 to present, this study had an unheard of dense surface automated meteorological station array of up to 5 meteorological buoys, 4 oil platforms, 2 island stations, and 11 coastal stations within 1 km of the beach. Most of the land stations are maintained by other projects. Only a large, a well funded project with backed by an agency with the long-view could dedicate the resources and effort into filling the mesoscale "holes" and maintaining long-term, remotely located stations. The result of the MMS funded project is a sufficiently dense surface station array to resolve the along-coast and cross-coast atmospheric mesoscale wind structure. Great temporal and spatial variation is found in the wind, wind stress and the wind stress curl, during the extended summer season. The MM5 atmospheric mesoscale model with appropriate boundary layer physics and high-resolution horizontal and vertical grid structure successfully simulates the measured wind field from large scale down to the lower end of the mesoscale. Atmospheric models without appropriate resolution and boundary layer physics fail to capture significant mesoscale wind features. Satellite microwave wind measurements generally capture the offshore synoptic scale temporal and spatial scale in twice-a-day snap shots but fail in the crucial, innermost coastal waters and the diurnal scale.

  11. [Separation in the mother-son relationship: an adolescent problem in Rainer Maria Rilke's story "Silent accompaniment"].

    Science.gov (United States)

    Wittstruck, W

    1995-01-01

    The story 'Quiet Accompanying' by Ranier Maria Rilke's early work is of special interest for research on adolescence. The story is a literary contribution to the separation conflict of parents and their maturing children, especially the separation crisis in the mother-son relationship. The story's suspense is derived from the son's desire to begin a new phase in life and his experience of being powerless regarding his ties to his family. Thereby the adolescent crisis of the male main character is indirectly picked out as the main theme in the description of the mother's separation crisis. In the mother's 'dream' where the departure for a sunday excursion is described, an image of the son's adolescence with the components search for identity, separation and closeness develops. The son's efforts finally fail because mother and son are captured in their relationship characterized by conflicts and fears.

    Full Text Available The article aims at shedding light on the search for God in the work of the German poet Rainer Maria Rilke. Rilke’s relentless search for God, who appears to be concealed (and obscured, threads through his entire work as a basso continuo and could be summed up into the motto of “searching for an immediate relationship”. The Christian tradition, to which Rilke has a highly ambivalent attitude, plays a crucial part in the relationship to God. The article considers the poet’s strong alignment to the relationship to everything terrestrial as an attempt to involve everything in the broader complex, also in the relationship to infinity.

    The use of LANDSAT multispectral ban scanner imagery to verify the relationship between the behavior of the Tres Marias reservoir and the dynamics of the Sao Francisco River supply basin is described. The dispersion of suspended sediments and their concentration in the surface layers of the water are considered. A five year survey of the region during both dry and rainy seasons was performed. The drainage network was analyzed based on the patterns of dessication, water rises and soil use in the supply basin. Surface layers of the reservoir were tabulated as a function of the levels of gray in the imagery. In situ observations of water depth and reflectance were performed. Ground truth and LANDSAT data were correlated to determine the factors affecting the dynamics of the supply basin.

    Full Text Available What have been the implications of the social and productive alliance of Maria la Baja for palm oil production in terms of local development of the municipality? It is from this question, that the article focuses its attention on the trajectory of a palm oil producing territory, and the state policies aimed at promoting this activity. By signaling the convergence of natural and social conditions unique to the territory, through agricultural policies defined by a central state in response to factor conditions that favor the cultivation of palm oil, justified by a discourse of territorial clustering of productive actors, the article concludes that the discourse does not suit the reality of the territory.

The Cantigas, compiledin the end of the thirteenth century by Afonso X and hiscollaborators from Toledo, are one of the most extensive collectionsof poetry, iconography and music in Medieval Portuguese.Cambraia (2000 and Cunha (1966 were taken into account, dueto their regularity and meticulousness. Emphasis was given to theanalysis on the way the author deals with the extent of theGlossary, the constitution of its articles and the idiomaticexpressions. The absence of explicit norms to elaborate theGlossary is a serious deficiency of this edition, forcing its readerto deduce these norms. It is not our intention to find solutions toall the omissions found in the Glossary, but to point out a bodyof clear and coherent norms.

    Full Text Available New coefficients were determined for the weighting term for cloudiness in the Brunt-Penman equation using the rate of solar radiation (RK in place of the rate of sunshine duration (n/N. The coefficients in the Brutsaert method proposed for daytime in southern Brazil were also tested and adjusted, and the method was selected which gave the more accurate daily results in relation to the original Brunt-Penman equation, for Santa Maria in the state of Rio Grande do Sul, Brazil (RS. Meteorological data covering 2,472 days obtained from the automatic and conventional weather stations in Santa Maria were used. The coefficients were adjusted by linear and nonlinear regression methods depending on the model, using 2/3 of the data. The adjusted equations were tested with the remaining 1/3 of the data. The Brunt-Penman equation modified by the term for cloudiness weighted both for solar radiation incident on the surface with no cloudiness (RK,R and for solar radiation incident at the top of the atmosphere (RK,K, were those that resulted in the best statistical indices relative to the original Brunt-Penman equation. In those equations the boundary conditions, 0.3 ≥ RK,R ≥ 1 or RK,K ≤ 0.22, were imposed. Although having similar statistical indices, a sensitivity analysis showed that the Brutsaert equation and other weightings for cloudiness resulted in larger deviations when compared to the original Brunt-Penman equation, in addition to having greater complexity for practical application.

    Full Text Available According to the documentary information and to the prospectings performed by means of the georadar, beneath the floor of the Church of Santa Maria of Scandiano (RE, it has been possible to locate the sepulchral crypts where the poet Matteo Maria Boiardo and other members of his family, such as his father Giovanni, his grandfather Feltrino and maybe his wife Taddea Gonzaga and one of his sons, Camillo, must have been buried. The exploration of these sepulchral crypts has led to the recovery of the skeletal remains belonging altogether to at least 20 persons (adults and children. Among them, 3 have been discovered into a sepulchral room and the rest into an adjacent tomb. Among the first ones, a person, with the same sex, age of death, sturdiness, height and physical characteristics of the poet Boiardo, has been identified. As confirmation of this probable identity, the genetic profile of this man, got from the nuclear dna sample taken from his body, has come out to be compatible with a possible father/child relationship, this result has been compared to the one gotten from the find found into the adjacent room where the poet's father and grandfather had to be buried. The body of a second person, of female sex and well on in years, with a genetic profile different from the previous ones, could be identified with Boiardo's wife. For what regards the body of the third man, besides it is not possible to exclude that it belongs to Camillo, the poet's son dead when he was very young, it has not been possible yet, to get enough proofs able to confirm this theory.

    Streptococcus mutans, a Gram positive facultative anaerobe, is one among the approximately seven hundred bacterial species to exist in human buccal cavity and cause dental caries. Quorum sensing (QS) is a cell-density dependent communication process that respond to the inter/intra-species signals and elicit responses to show behavioral changes in the bacteria to an aggressive forms. In accordance to this phenomenon, the S. mutans also harbors a Competing Stimulating Peptide (CSP)-mediated quorum sensing, ComCDE (Two-component regulatory system) to regulate several virulence-associated traits that includes the formation of the oral biofilm (dental plaque), genetic competence and acidogenicity. The QS-mediated response of S. mutans adherence on tooth surface (dental plaque) imparts antibiotic resistance to the bacterium and further progresses to lead a chronic state, known as periodontitis. In recent years, the oral streptococci, S. mutans are not only recognized for its cariogenic potential but also well known to worsen the infective endocarditis due to its inherent ability to colonize and form biofilm on heart valves. The review significantly appreciate the increasing complexity of the CSP-mediated quorum-sensing pathway with a special emphasis to identify the plausible drug targets within the system for the development of anti-quorum drugs to control biofilm formation and associated risks.

  5. Three-layered metallodielectric nanoshells: plausible meta-atoms for metamaterials with isotropic negative refractive index at visible wavelengths.

    A three-layered Ag-low-permittivity (LP)-high-permittivity (HP) nanoshell is proposed as a plausible meta-atom for building the three-dimensional isotropic negative refractive index metamaterials (NIMs). The overlap between the electric and magnetic responses of Ag-LP-HP nanoshell can be realized by designing the geometry of the particle, which can lead to the negative electric and magnetic polarizabilities. Then, the negative refractive index is found in the random arrangement of Ag-LP-HP nanoshells. Especially, the modulation of the middle LP layer can move the negative refractive index range into the visible region. Because the responses arise from the each meta-atom, the metamaterial is intrinsically isotropic and polarization independent. It is further found with the increase of the LP layer thickness that the negative refractive index range of the random arrangement shows a large blue-shift and becomes narrow. With the decrease of the filling fraction, the negative refractive index range shows a blue-shift and becomes narrow while the maximum of the negative refractive index decreases.

    Ribonucleoside 2',3'-cyclic phosphates (N>p's) are generated by multiple prebiotically plausible processes and are credible building blocks for the assembly of early RNA oligomers. While N>p's can be polymerized into short RNAs by non-enzymatic processes with variable efficiency and regioselectivity, no enzymatic route for RNA synthesis had been described. Here we report such a non-canonical 3'-5' nucleotidyl transferase activity. We engineered a variant of the hairpin ribozyme to catalyze addition of all four N>p's (2',3'-cyclic A-, G-, U-, and CMP) to the 5'-hydroxyl termini of RNA strands with 5' nucleotide addition enhanced in all cases by eutectic ice phase formation at -7 °C. We also observed 5' addition of 2',3'-cyclic phosphate-activated β-nicotinamide adenine dinucleotide (NAD>p) and ACA>p RNA trinucleotide, and multiple additions of GUCCA>p RNA pentamers. Our results establish a new mode of RNA 3'-5' extension with implications for RNA oligomer synthesis from prebiotic nucleotide pools.

  7. Plausibility of stromal initiation of epithelial cancers without a mutation in the epithelium: a computer simulation of morphostats

    Full Text Available Abstract Background There is experimental evidence from animal models favoring the notion that the disruption of interactions between stroma and epithelium plays an important role in the initiation of carcinogenesis. These disrupted interactions are hypothesized to be mediated by molecules, termed morphostats, which diffuse through the tissue to determine cell phenotype and maintain tissue architecture. Methods We developed a computer simulation based on simple properties of cell renewal and morphostats. Results Under the computer simulation, the disruption of the morphostat gradient in the stroma generated epithelial precursors of cancer without any mutation in the epithelium. Conclusion The model is consistent with the possibility that the accumulation of genetic and epigenetic changes found in tumors could arise after the formation of a founder population of aberrant cells, defined as cells that are created by low or insufficient morphostat levels and that no longer respond to morphostat concentrations. Because the model is biologically plausible, we hope that these results will stimulate further experiments.

    Full Text Available Previous work has shown that prior experience in language brokering (informal translation may facilitate the processing of meaning within and across language boundaries. The present investigation examined the influence of brokering on bilinguals' processing of two word collocations with either a literal or a figurative meaning in each language. Proficient Spanish-English bilinguals classified as brokers or non-brokers were asked to judge if adjective+noun phrases presented in each language made sense or not. Phrases with a literal meaning (e.g., stinging insect were interspersed with phrases with a figurative meaning (e.g., stinging insult and non-sensical phrases (e.g., stinging picnic. It was hypothesized that plausibility judgments would be facilitated for literal relative to figurative meanings in each language but that experience in language brokering would be associated with a more equivalent pattern of responding across languages. These predictions were confirmed. The findings add to the body of empirical work on individual differences in language processing in bilinguals associated with prior language brokering experience.

    Glacial-state greenhouse gas concentrations and Southern Hemisphere climate conditions persisted until ∼17.7 ka, when a nearly synchronous acceleration in deglaciation was recorded in paleoclimate proxies in large parts of the Southern Hemisphere, with many changes ascribed to a sudden poleward shift in the Southern Hemisphere westerlies and subsequent climate impacts. We used high-resolution chemical measurements in the West Antarctic Ice Sheet Divide, Byrd, and other ice cores to document a unique, ∼192-y series of halogen-rich volcanic eruptions exactly at the start of accelerated deglaciation, with tephra identifying the nearby Mount Takahe volcano as the source. Extensive fallout from these massive eruptions has been found >2,800 km from Mount Takahe. Sulfur isotope anomalies and marked decreases in ice core bromine consistent with increased surface UV radiation indicate that the eruptions led to stratospheric ozone depletion. Rather than a highly improbable coincidence, circulation and climate changes extending from the Antarctic Peninsula to the subtropics-similar to those associated with modern stratospheric ozone depletion over Antarctica-plausibly link the Mount Takahe eruptions to the onset of accelerated Southern Hemisphere deglaciation ∼17.7 ka.

    We report on the results from {\\it Suzaku} X-ray observations of the radio complex region called Kookaburra, which includes two adjacent TeV $\\gamma$-ray sources HESS J1418-609 and HESS J1420-607. The {\\it Suzaku} observation revealed X-ray diffuse emission around a middle-aged pulsar PSR J1420-6048 and a plausible PWN Rabbit with elongated sizes of $\\sigma_{\\rm X}=1^{\\prime}.66$ and $\\sigma_{\\rm X}=1^{\\prime}.49$, respectively. The peaks of the diffuse X-ray emission are located within the $\\gamma$-ray excess maps obtained by H.E.S.S. and the offsets from the $\\gamma$-ray peaks are $2^{\\prime}.8$ for PSR J1420-6048 and $4^{\\prime}.5$ for Rabbit. The X-ray spectra of the two sources were well reproduced by absorbed power-law models with $\\Gamma=1.7-2.3$. The spectral shapes tend to become softer according to the distance from the X-ray peaks. Assuming the one zone electron emission model as the first order approximation, the ambient magnetic field strengths of HESS J1420-607 and HESS J1418-609 can be estimate...

    Context. Very high-energy (VHE) $\\gamma$-ray measurements of distant TeV blazars can be nicely explained by TeV spectra induced by ultra high-energy cosmic rays. Aims. We develop a model for a plausible origin of hard spectra in distant TeV blazars. Methods. In the model, the TeV emission in distant TeV blazars is dominated by two mixed components. The first is the internal component with the photon energy around 1 TeV produced by inverse Compton scattering of the relativistic electrons on the synchrotron photons (SSC) with a correction for extragalactic background light absorbtion and the other is the external component with the photon energy more than 1 TeV produced by the cascade emission from high-energy protons propagating through intergalactic space. Results. Assuming suitable model parameters, we apply the model to observed spectra of distant TeV blazars of 1ES 0229+200. Our results show that 1) the observed spectrum properties of 1ES 0229+200, especially the TeV $\\gamma$-ray tail of the observed spect...

    We report an indication (3.22 sigma) of ~ 1860 Hz quasi-periodic oscillations from a neutron star low-mass X-ray binary 4U 1636-536. If confirmed, this will be by far the highest frequency feature observed from an accreting neutron star system, and hence could be very useful to understand such systems. This plausible timing feature was observed simultaneously with lower (~ 585 Hz) and upper (~ 904 Hz) kilohertz quasi-periodic oscillations. The two kilohertz quasi-periodic oscillation frequencies had the ratio of ~ 1.5, and the frequency of the alleged ~ 1860 Hz feature was close to the triple and the double of these frequencies. This can be useful to constrain the models of all the three features. In particular, the ~ 1860 Hz feature could be (1) from a new and heretofore unknown class of quasi-periodic oscillations, or (2) the first observed overtone of lower or upper kilohertz quasi-periodic oscillations. Finally we note that, although the relatively low significance of the ~ 1860 Hz feature argues for caut...

    Provision of clean water is one of the most important issues worldwide because of continuing economic development and the steady increase in the global population. However, clean water resources are decreasing everyday, because of contamination with various pollutants including organic chemicals. Pharmaceutical and personal care products, herbicides/pesticides, dyes, phenolics, and aromatics (from sources such as spilled oil) are typical organics that should be removed from water. Because of their huge porosities, designable pore structures, and facile modification, metal-organic frameworks (MOFs) are used in various adsorption, separation, storage, and delivery applications. In this review, the adsorptive purifications of contaminated water with MOFs are discussed, in order to understand possible applications of MOFs in clean water provision. More importantly, plausible adsorption or interaction mechanisms and selective adsorptions are summarized. The mechanisms of interactions such as electrostatic interaction, acid-base interaction, hydrogen bonding, π-π stacking/interaction, and hydrophobic interaction are discussed for the selective adsorption of organics over MOFs. The adsorption mechanisms will be very helpful not only for understanding adsorptions but also for applications of adsorptions in selective removal, storage, delivery and so on.

    The SLEUTH urban growth model is applied to a binational dryland watershed to envision and evaluate plausible future scenarios of land use change into the year 2050. Our objective was to create a suite of geospatial footprints portraying potential land use change that can be used to aid binational decision-makers in assessing the impacts relative to sustainability of natural resources and potential socio-ecological consequences of proposed land-use management. Three alternatives are designed to simulate different conditions: (i) a Current Trends Scenario of unmanaged exponential growth, (ii) a Conservation Scenario with managed growth to protect the environment, and (iii) a Megalopolis Scenario in which growth is accentuated around a defined international trade corridor. The model was calibrated with historical data extracted from a time series of satellite images. Model materials, methodology, and results are presented. Our Current Trends Scenario predicts the footprint of urban growth to approximately triple from 2009 to 2050, which is corroborated by local population estimates. The Conservation Scenario results in protecting 46% more of the Evergreen class (more than 150,000 acres) than the Current Trends Scenario and approximately 95,000 acres of Barren Land, Crops, Deciduous Forest (Mesquite Bosque), Grassland/Herbaceous, Urban/Recreational Grasses, and Wetlands classes combined. The Megalopolis Scenario results also depict the preservation of some of these land-use classes compared to the Current Trends Scenario, most notably in the environmentally important headwaters region. Connectivity and areal extent of land cover types that provide wildlife habitat were preserved under the alternative scenarios when compared to Current Trends.

    The neural mechanisms underlying response inhibition and related disorders are unclear and controversial for several reasons. First, it is a major challenge to assess the psychological bases of behaviour, and ultimately brain-behaviour relationships, of a function which is precisely intended to suppress overt measurable behaviours. Second, response inhibition is difficult to disentangle from other parallel processes involved in more general aspects of cognitive control. Consequently, different psychological and anatomo-functional models coexist, which often appear in conflict with each other even though they are not necessarily mutually exclusive. The standard model of response inhibition in go/no-go tasks assumes that inhibitory processes are reactively and selectively triggered by the stimulus that participants must refrain from reacting to. Recent alternative models suggest that action restraint could instead rely on reactive but non-selective mechanisms (all automatic responses are automatically inhibited in uncertain contexts) or on proactive and non-selective mechanisms (a gating function by which reaction to any stimulus is prevented in anticipation of stimulation when the situation is unpredictable). Here, we assessed the physiological plausibility of these different models by testing their respective predictions regarding event-related BOLD modulations (forward inference using fMRI). We set up a single fMRI design which allowed for us to record simultaneously the different possible forms of inhibition while limiting confounds between response inhibition and parallel cognitive processes. We found BOLD dynamics consistent with non-selective models. These results provide new theoretical and methodological lines of inquiry for the study of basic functions involved in behavioural control and related disorders. Copyright © 2017 Elsevier B.V.

  20. Combination of monoclonal antibodies and DPP-IV inhibitors in the treatment of type 1 diabetes: a plausible treatment modality?

    Dubala, Anil; Gupta, Ankur; Samanta, Malay K

    2014-07-01

    Regulatory T cells (Tregs) are crucial for the maintenance of immunological tolerance. Type 1 diabetes (T1D) occurs when the immune-regulatory mechanism fails. In fact, T1D is reversed by islet transplantation but is associated with hostile effects of persistent immune suppression. T1D is believed to be dependent on the activation of type-1 helper T (Th1) cells. Immune tolerance is liable for the activation of the Th1 cells. The important role of Th1 cells in pathology of T1D entails the depletion of CD4(+) T cells, which initiated the use of monoclonal antibodies (mAbs) against CD4(+) T cells to interfere with induction of T1D. Prevention of autoimmunity is not only a step forward for the treatment of T1D, but could also restore the β-cell mass. Glucagon-like peptide (GLP)-1 stimulates β-cell proliferation and also has anti-apoptotic effects on them. However, the potential use of GLP-1 as a possible method to restore pancreatic β-cells is limited due to rapid degradation by dipeptidyl peptidase (DPP)-IV. We hypothesize that treatment with combination of CD4 mAbs and DPP-IV inhibitors could prevent/reverse T1D. CD4 mAbs have the ability to induce immune tolerance, thereby arresting further progression of T1D; DPP-IV inhibitors have the capability to regenerate the β-cell mass. Consequently, the combination of CD4 mAbs and DPP-IV inhibitor could avoid or at least minimize the constraints of intensive subcutaneous insulin therapy. We presume that if this hypothesis proves correct, it may become one of the plausible therapeutic options for T1D.

    Fatty acid synthase (FASN, UniProt ID: P49327) is a multienzyme dimer complex that plays a critical role in lipogenesis. Consequently, this lipogenic enzyme has gained tremendous biomedical importance. The role of FASN and its inhibition is being extensively researched in several clinical conditions, such as cancers, obesity, and diabetes. X-ray crystallographic structures of some of its domains, such as β-ketoacyl synthase, acetyl transacylase, malonyl transacylase, enoyl reductase, β-ketoacyl reductase, and thioesterase, (TE) are already reported. Here, we have attempted an in silico elucidation of the uncrystallized dehydratase (DH) catalytic domain of human FASN. This theoretical model for DH domain was predicted using comparative modeling methods. Different stand-alone tools and servers were used to validate and check the reliability of the predicted models, which suggested it to be a highly plausible model. The stereochemical analysis showed 92.0% residues in favorable region of Ramachandran plot. The initial physiological substrate β-hydroxybutyryl group was docked into active site of DH domain using Glide. The molecular dynamics simulations carried out for 20 ns in apo and holo states indicated the stability and accuracy of the predicted structure in solvated condition. The predicted model provided useful biochemical insights into the substrate-active site binding mechanisms. This model was then used for identifying potential FASN inhibitors using high-throughput virtual screening of the National Cancer Institute database of chemical ligands. The inhibitory efficacy of the top hit ligands was validated by performing molecular dynamics simulation for 20 ns, where in the ligand NSC71039 exhibited good enzyme inhibition characteristics and exhibited dose-dependent anticancer cytotoxicity in retinoblastoma cancer cells in vitro.

    We illustrate an analysis procedure that explores the robustness and overall productivity of a reservoir management system under plausible assumptions about climate fluctuation and change. Results are presented based on a stylized version of a multi-use reservoir management model adapted from Angat Dam, Philippines. It represents a modest-sized seasonal storage reservoir in a climate with a pronounced dry season. The reservoir management model focuses on October-March, during which climatological inflow declines due to the arrival of the dry season, and reservoir management becomes critical and challenging. Inflow is assumed to be impacted by climate fluctuations representing interannal variation (white noise), decadal to multidecadal variation (MDV, here represented by a stochastic autoregressive process) and global change (GC), here represented by a systematic linear trend in seasonal inflow total over the simulation period of 2008-2047. Reservoir reliability, and risk of extreme persistent water shortfall, is assessed under different combinations and magnitudes of GC and MDV. We include an illustration of adaptive management, using seasonal forecasts and updated climate normals. A set of seasonal forecast and observed inflow values are generated for 2008-2047 by randomly rearranging the forecast-observed pairs for 1968-2007. Then, trends are imposed on the observed series, with differing assumptions about the extent to which the seasonal forecasts can be expected to track the trend. We consider the framework presented here well-suited to providing insights about managing the climate risks in reservoir operations, providing guidance on expected benefits and risks of different strategies and climate scenarios.

    Este trabalho teve como objetivo realizar uma análise multitemporal da cobertura florestal da microbacia do Arroio Grande, Santa Maria, RS. Foram utilizadas quatro imagens de satélite: LANDSAT 5 (1987, LANDSAT 5 (1995, LANDSAT 7 (2002 e CBERS 2 (2005. As imagens foram classificadas empregando-se o algoritmo Bhattacharya. Após a classificação das imagens, foi realizado o cruzamento dos mapas temáticos. Como resultado, obteve-se mapas com os seguintes usos da terra: cobertura florestal, regeneração e desmatamento, ou seja, as florestas que permaneceram inalteradas de uma época para outra, as que regeneraram e as que foram desmatadas. Para um período de 18 anos, a cobertura florestal aumentou 10,24% na área da microbacia, passando de 14.135,42 ha (40,01% em 1987 para 17.752,20 ha (50,25% em 2005. Isto ocorreu devido à entrada em vigor do Código Florestal Estadual, à conscientização dosproprietários rurais e à implantação em maiorescala de povoamentos de espécies exóticas no estado. 
    This work aims to carry out a multitemporal analysis of the forest cover of Arroio Grande small hydrological basin located in Santa Maria, RS, Brazil. Four satellite images were used: LANDSAT 5 (1987, LANDSAT 5 (1995, LANDSAT 7 (2002 and CBERS 2 (2005. The images were classified according to the Bhattacharya algorithm. After the classification of such images, the crossing of the thematic maps was accomplished. Maps with different land uses were obtained: unaffected forest cover, regeneration and deforestation for the period 1987 – 2005. During 18 years, the forest cover increased 10,24% in the basin area, changing from 14.135,42 ha (40,01% in 1987 to 17.752,20 ha (50,25% in 2005. This happened because the State Forest Law has become effective as well as the rural owners’ consciousness and also due to increment of exotic forest plantations in the State. 

  7. De llibertat, autoritat, in/dependències (a la vida i l'obra de Maria-Mercè Marçal

    Full Text Available This article pays attention to two moments in the life and work (inseparably united of Maria Mercè Marçal. The first refers to a search of small objects presided by the moon. Taking this search as a motif, the freedom which the poet confers to the nocturnal light –mythical and magical symbol of femaleness– and, therefore, to that which symbolises the heavenly body, is revealed. The second moment revolves around the reflection of Marçal on the “female authority”. A concept which this author, inspired by the filosofical community Diotima, distinguishes from power. Throughout history, Maria-Mercè Marçal remarked, many women have gained strength from the free atribution of authority to other women, to their texts, to their experiences.

    Full Text Available In this work we propose to analyze the mediated debate on Maria da Penha Law in the newspapers Folha de São Paulo and O Globo, during the period 2001-2012. We use here the “deliberative” theoretical matrix, taking in consideration and dialoguing with the critiques of feminist theoreticians (Nancy Fraser and Iris Young, in particular who have inscribed such a conception in democratic theory. We defend that oppression which originates from gender inequalities cannot do without public debate. Thus, we seek to identify how the arguments and discursive relations on Maria da Penha Law were constructed in the two newspapers in question in two distinct periods: the phase of the construction of the law (2001-2005, and that of its sanctioning and implementation (2006-2012. Our analysis is based on a qualitative methodology focusing on the study of deliberation and media, conjugated with a qualitative analysis framework.

  9. First record of Ginkgo-related fertile organs (Hamshawvia, Stachyopitys) and leaves (Baiera, Sphenobaiera) in the Triassic of Brazil, Santa Maria formation

    This paper describes new ginkgophytes recently discovered in a new exposure of the original type section of the Passo das Tropas Member, Santa Maria Formation, linked to Paraná Basin succession. The well-preserved fossils come from a very fine red laminated mudstone representing a lacustrine interval, within a broader low-sinuosity fluvial succession. The material occurs in a Dicroidium-dominated assemblage and is represented by the leaves Baiera and Sphenobaiera, accompanied by the fertile structures Hamshawvia and Stachyopytis. Cuticle fragments preserved on leaf impressions of Sphenobaiera schenkii show xeromorphic features. The geology, paleogeography and paleoclimate of the Passo das Tropas Member (PTM), Santa Maria Formation, is discussed. By comparing these ginkgophytes with those from other Gondwanan assemblages, the Brazilian deposits earlier assigned to Anisian-Ladinian age can now be extended to the Carnian age.

    Full Text Available Maria Firmina dos Reis ventured to be a writer within the possibilities that Brazilian society offered in the XIX century. She dribbled the hardships imposed upon women of the period, publishing, in 1859, her romance ‘Ursula’  a unique work, written by a woman of African descent, in which she provides evidence of the condition of subalternity imposed upon women, Africans and their descendants by the patriarchal regime that characterized nineteenth century Brazil. Art and real life are intertwined, contributing to the rescue of these historical subjects. In analyzing their struggles to occupy spaces previously denied to them and looking at Maria Firmina’s work from the perspective of gender and ethnicity, we find scathing denunciations of the predicament of women and blacks in the society of the period.

    A year after the commissioning of the Synchrocyclotron (SC), the first experiments were already starting to bear fruit. In July 1958, Tito Fazzini, Giuseppe Fidecaro, Alec Merrison, Helmut Paul and Alvin Tollestrup produced conclusive evidence that approximately one pion in ten thousand decayed into an electron and a neutrino, as predicted by the weak interaction theory. This, the first of CERN's great discoveries, effectively put an end to the controversy that had been raging at the time. A few years later, Giuseppe Fidecaro began a collaboration at CERN with his wife Maria. In the image, Giuseppe and Maria Fidecaro in 1963, surrounded by spark chambers, inside the detector for the experiment on the decay of a rho meson into a pi meson and a photon.

    The multipurpose, high flux research reactor MARIA in Otwock - Swierk is an open-pool type, water and beryllium moderated and graphite reflected. There are two not occupied experimental H1 and H2 horizontal channels with complex of empty rooms beside them. Making use of these two channels is not in conflict with other research or commercial employing channels. They can work simultaneously, moreover commercial channels covers the cost of reactor working. Such conditions give beneficial possibility of creating epithermal neutron stand for researches in various field at the horizontal channel H2 of MARIA reactor (co-organization of research at H1 channel is additionally planned). At the front of experimental channels the neutron flux is strongly thermalized - neutrons with energies above 0.625 eV constitute only ∼2% of the total flux. This thermalized neutron flux will be used to achieve high flux of epithermal neutrons at the level of 2x10{sup 9} n cm{sup -2}s{sup -1} by uranium neutron converter (fast neutron production - conversion of reactor core thermal neutrons to fast neutrons - and then filtering, moderating and finally cutting of unwanted gamma radiation). The intelligent converter will be placed in the reactor pool, near the front of the H2 channel. It will replace one graphite block at the periphery of MARIA graphite reflector. The converter will consist of 20 fuel elements - low enriched uranium plates. A fuel plate will be a part which will measure 110 mm wide by 380 mm long and will consist of a thin layer of uranium sealed between two aluminium plates. These plates, once assembled, form the fuel element used in converter. The plates will be positioned vertically. There are several important requirements which should be taken into account at the converter design stage: -maximum efficiency of the converter for neutrons conversion, -cooling of the converter need to be integrated with the cooling circuit of the reactor pool and if needed equipped with

    Full Text Available U-Pb dating of zircon was undertaken with the Beijing SHRIMP II (sensitive high resolution ion microprobe on anamphibolite facies granodiorite and an almandine-albite granulite from the Santa Maria Chico Granulitic Complex, southern Brazilian Shield. This work was also done to unravel protolith ages which are often hidden in the array of partly reset data. The obtained metamorphic ages of the granodiorite gneiss and the granulite are 2035 ± 9 Ma and 2006 ± 3 Ma, respectively. These data are within the range of metamorphic ages determined in previous studies (2022 ± 18 Ma and 2031 ± 40 Ma. However, protolith ages for the granodiorite (2366 ± 8 Ma and the granulite (2489 ± 6 Ma were obtained which are outside the previously recognized range (> 2510-2555 Ma. The magmatic protolith age of the granodiorite refers to a previously little known magmatic event in the shield. Further investigations may demonstrate that amphibolite facies zircon crystals are useful as a window into geological events in associated granulites, because zircon ages are blurred in the studied granulites.Um granodiorito de fácies anfibolito e um almandina-albita granulito do Complexo Granulítico Santa Maria Chico, porção sul do Escudo Brasileiro, foram datados pelo método U-Pb em zircão por Beijing SHRIMP II (sensitive high resolution ion microprobe. Esta investigação inclui a determinação das idades de protólitos que estão ocultas no conjunto de dados parcialmente re-equilibrados. As idades metamórficas obtidas no gnaisse granodiorítico e no granulito são 2035 ±9 Ma e 2006 ±3 Ma, respectivamente. Esses dados estão dentro da variação das idades metamórficas determinadas em estudos anteriores (2022 ±18 Ma e 2031 ±40 Ma. No entanto, as idades do protólito do granodiorito (2366 ±8 Ma e do granulito (2489 ±6 Ma estão fora da variação de idades ( > 2510-2555 Ma reconhecidas anteriormente.

    Full Text Available Il contributo analizza un ciclo figurativo di contenuto eucaristico eseguito a Macerata alla fine del Cinquecento: la cappella maggiore della chiesa di Santa Maria delle Vergini. In particolare, è stata riservata attenzione alla committenza, ai dati storico-documentari che ne attestano le vicende decorative, ai caratteri stilistici e iconografici delle opere pittoriche. La cappella, di patronato della Compagnia dei Bifolchi, la confraternita degli agricoltori maceratesi, costituisce un caso quasi unico, per complessità e ottimo stato di conservazione, di cantiere decorativo della Controriforma nelle Marche. Affidata inizialmente al pittore maceratese Gaspare Gasparrini, alla sua morte la decorazione fu assegnata ai fratelli Cesare e Vincenzo Conti, pittori marchigiani precedentemente attivi nei prestigiosi cantieri romani promossi da Sisto V. La cappella ospita una tela con l’Ultima Cena e scene veterotestamentarie connesse all’eucarestia, opere che espongono e sottolineano, con particolari accorgimenti iconografici, le dottrine e i dogmi ribaditi al Concilio di Trento.   This paper consists of an analysis regarding an Eucharistic figurative and decorative cycle carried out in Macerata at the end of the 16th century: the main chapel of the church of Santa Maria delle Vergini. This research has been focusing on historical and archival information about the cycle, on its patrons and on the stylistic and iconographic patterns of the paintings. The chapel, whose patrons were the “Bifolchi”, a civic confraternity of farmers, represents an almost unique case of artistic workshop in the Marche region during the age of Counter-Reformation, mainly due to its complexity and excellent state of preservation. The decoration of this chapel was initially commissioned to the painter Gaspare Gasparrini from Macerata: after his death, it was entrusted to the brothers Cesare and Vincenzo Conti, Marchisan painters who had been working in the roman

    Full Text Available The Dader Method used for pharmacotherapeutic follow-up has been a suitable course of action to detect and to solve problems concerned with medication. It is easily fitted to local conditions of rural communities. The objective of this study was to evaluate the appropriateness of the Dader Method in a rural community of Mexico. The pharmaceutic service was offered to 300 children from Santa Maria Acuexcomac, of which, only 102 volunteers accepted to participate. A survey revealed 62 cases of parasitism caused by Entamoeba histolytic, Hymenolepis nana and/or Giardia lamblia. The doctor prescribed Quinfamida for amibiasis, albendazol for hymenolepiasis and giardiasis, or both medicines for amibiasis with hymenolepiasis and/or giardiasis. 96,9 % of pharmacotherapeutic follow-up -treated patients showed pharmacological adhesion on average at the end of the medication programmme, and 76 % of them did not presented parasitism after a second coproparasitoscopic analysis. In a second stage of the study we administered metronidazol to treat amibiasis and/or giardiasis, and prazicuantel to hymenolepiasis. 81,8 % of pharmacotherapeutic follow-up -treated patient showed adhesion. At the end of the study none of the PF-treated patients presented any parasitism.
