  4. Historia and materia: the philosophical implications of Francis Bacon's natural history.

    PubMed

    Giglioni, Guido

    2012-01-01

    This article examines the philosophical implications underlying Bacon's views on historical knowledge, paying special attention to that variety of historical knowledge described by Bacon as "natural." More specifically, this article explores the interplay of history (historia) and fable (fabula). In the sphere of thought, fabula is the equivalent to materia in nature. Both are described by Bacon as being "versatile" and "pliant." In Bacon's system of knowledge, philosophy, as the domain of reason, starts from historiae and fabulae, once memory and the imagination have fulfilled their cognitive tasks. This means that, for Bacon, there is no such thing as a pure use of reason. He advocates a kind of reason that, precisely because it is involved with matter's inner motions (its "appetites," in Bacon's characteristic language), is constitutively 'impure'. The article shows how the terms historia and fabula cover key semantic areas in defining Bacon's philosophy: historia may mean "history" as well as "story,"fabula "myth" as well "story". In both cases, we can see significant oscillations from a stronger meaning (close to those of matter and nature) to a weaker one (connected to wit and imagination), as if the power of nature decreases moving from histories and myths to stories. On the other hand, there are cases in which Bacon seems to stick to a diachronic view of the meaning of fables and histories, such that the transition from myths to history, especially natural history, is described as a collective effort towards reality and enlightenment.

  5. The sources of Gessner's pictures for the Historia animalium.

    PubMed

    Kusukawa, S

    2010-07-01

    Gessner's sources for the pictures in his Historia animalium were varied in kind and in quality. This should be understood within the larger context of the Historia animalium in which Gessner sought to collect everything ever written about animals, an enterprise that could not be completed by a single individual. Just as Gessner did not distil or reduce similar texts but retained these as well as contradictory or false textual descriptions as part of a repository of knowledge, so also Gessner included several pictures of the same animal, false or badly drawn ones, and juxtaposed erroneous and 'true' images. The attribution of images to witnesses and correspondences also reflects Gessner's strategy to credit those who drew his attention to new information first. The sources of Gessner's images thus indicate how his visual world encompassed more than the strictly self-observable, and a pictorial practice that was intimately connected with textual traditions and intellectual networks.

  6. Poinsinet's Edition of the Naturalis historia (1771-1782) and the Revival of Pliny in the Sciences of the Enlightenment.

    PubMed

    Loveland, Jeff; Schmitt, Stéphane

    2015-01-01

    This paper analyses the revival of Pliny's Naturalis historia within the scientific culture of the late eighteenth and early nineteenth centuries, focusing on a French effort to produce an edition with annotations by scientists and scholars. Between the Renaissance and the early eighteenth century, the Naturalis historia had declined in scientific importance. Increasingly, it was relegated to the humanities, as we demonstrate with a review of editions. For a variety of reasons, however, scientific interest in the Naturalis historia grew in the second half of the eighteenth century. Epitomizing this interest was a plan for a scientifically annotated, Latin-French edition of the Naturalis historia. Initially coordinated by the French governmental minister Malesherbes in the 1750s, the edition was imperfectly realized by Poinsinet a few decades later. It was intended to rival two of the period's other distinguished multi-volume books of knowledge, Diderot and D'Alembert's Encyclopédie and Buffon's Histoire naturelle, to which we compare it. Besides narrating the scientific revival of the Historia naturalis during this period, we examine its causes and the factors contributing to its end in the first half of the nineteenth century.

  9. Arabidopsis floral phytomer development: auxin response relative to biphasic modes of organ initiation

    2014-01-01

    In the Arabidopsis inflorescence meristem (IM), auxin is considered a prepatterning signal for floral primordia, whereas a centripetal mode of positional information for floral organ identity is inherent to the ABCE model. However, spatio-temporal patterns of organ initiation in each whorl at the earliest initiation stages are largely unknown. Evidence suggests that initial flower development occurs along an abaxial/adaxial axis and conforms to phytomer theory. Use of the founder cell marker DORNRÖSCHEN-LIKE (DRNL) as a tool in leafy, puchi, and apetala 1 cauliflower mutant backgrounds suggests that bract founder cells are marked at the IM periphery. The DRNL transcription domain in the wild-type IM is spatially discrete from DR5 expression, suggesting that bract initiation is independent of canonical auxin response. When bracts develop in lfy and puchi mutant floral primordia the initiation of lateral sepals precedes the specification of medial sepals compared with wild type, showing an interplay between bract and abaxial sepal founder cell recruitment. In the perianthia (pan) mutant background, DRNL expression indicates that a radial outer whorl arrangement derives from splitting of sepal founder cell populations at abaxial and adaxial positions. This splitting of incipient sepal primordia is partially dependent on PRESSED FLOWER (PRS) activity and implies that sepal specification is independent of WUSCHEL and CLAVATA3 expression, as both marker genes only regain activity in stage-2 flowers, when patterning of inner floral organs switches to a centripetal mode. The transition from an initially abaxial/adaxial into a centripetal patterning programme, and its timing represent an adaptive trait that possibly contributes to variation in floral morphology, especially unidirectional organ initiation.

    The article describes the authors and works which were quoted by the Franciscan Juan Gil de Zamora in his Historia naturalis, a scientific encyclopaedia written between c. 1275 and before 1296, probably in the Franciscan monastery of Zamora (Kingdom of Castille). Juan Gil made wide use of the Avicenna's Canon, Gilbertus de Aquila (Anglicus)'s Compendium medicine, and Salernitan medical literature. His work contributed to the diffusion of these medical authors and works throughout the Christian intellectual milieu of late medieval Castille. This diffusion was not without problems.

  13. Jean-Jacques Rousseau's copy of Albrecht von Haller's Historia stirpium indigenarum Helvetiae inchoata (1768).

    Jean-Jacques Rousseau sold his botanical texts to Daniel Malthus (father of Thomas Malthus) about 1775. Two of these are now in the Old Library, Jesus College, Cambridge, but all the rest have long been thought lost. However, a copy of Albrecht von Haller's Historia stirpium indigenarum Helvetiae inchoata (1768) in the Lindley Library, Royal Horticultural Society, London, bears Rousseau's name and seems to have been annotated by him. The volume contains the bookplate of Jane Dalton, a cousin to whom Malthus willed "all[his] Botanical Books in which the name of Rousseau is written". Haller was well-known to Rousseau, who while in exile in the Swiss Jura (1763-1765), studied under one of Haller's collaborators, Abraham Gagnebin. Rousseau cited Haller's entry 762 when describing a species of Seseli to the Duchess of Portland.

  14. Statistical mechanics and combinatorics of some discrete lattice models

    NASA Astrophysics Data System (ADS)

    Ayyer, Arvind

    Many problems in statistical physics involve enumeration of certain objects. In this thesis, we apply ideas from combinatorics and statistical physics to understand three different lattice models. (I) We investigate the structure of the nonequilibrium stationary state (NESS) of a system of first and second class particles on L sites of a one-dimensional lattice in contact with first class particle reservoirs at the boundary sites and second class particles constrained to lie the system. The internal dynamics are described by the usual totally asymmetric exclusion process (TASEP) with second class particles. We show in a conceptually simple way how pinned and unpinned (fat) shocks determine the general structure of the phase diagram. We also point out some unexpected features in the microscopic structure of the NESS both for finite L and in the limit L → infinity. In the latter case the local distribution of second class particles is given by an equilibrium pressure ensemble with a pair potential between neighboring particles which grows logarithmically with distance. (II) We model a long linear polymer constrained between two plates as a walk on a two-dimensional lattice constrained to lie between two lines, x = y and x = y+w, which interacts with these lines via contact parameters s and t. The atomic steps of the walk can be taken to be from an arbitrary but fixed set S with the only condition being that the first coordinate of every element in S is strictly positive. For any such S and any w, we prescribe general algorithms (fully implemented in Maple) for the automated calculation of several mathematical and physical quantities of interest. (III) Ferrers (or Young) diagrams are very classical objects in representation theory, whose half-perimeter generating function of Ferrers diagrams is a straightforward rational function. We construct two new classes of Ferrers diagrams, which we call wicketed and gated Ferrers diagrams, which have internal voids in the

  15. A cladistic analysis of Aristotle's animal groups in the Historia animalium.

    The Historia animalium (HA) of Aristotle contains an extraordinarily rich compilation of descriptions of animal anatomy, development, and behaviour. It is believed that Aristotle's aim in HA was to describe the correlations of characters rather than to classify or define animal groups. In order to assess if Aristotle, while organising his character correlations, referred to a pre-existing classification that underlies the descriptions in HA, we carried out a cladistic analysis according to the following procedure: by disentangeling 147 species and 40 higher taxa-designations from 157 predicates in the texts, we transcribed Aristotle's descriptions on anatomy and development of animals in books I-V of HA into a character matrix for a cladistic analysis. By analysing the distribution of characters as described in his books, we obtained a non-phylogenetic dendrogram displaying 58 monophyletic groups, 29 of which have equivalents among Aristotle's group designations. Eleven Aristotelian groupings turned out to be non-monophyletic, and six of them are inconsistent with the monophyletic groups. Twelve of 29 taxa without equivalents in Aristotle's works have equivalents in modern classifications. With this analysis we demonstate there exists a fairly consistent underlying classification in the zoological works of Aristotle. The peculiarities of Aristotle's character basis are discussed and the dendrogram is compared with a current phylogenetic tree.

    This article reports historical ethnobotany research conducted from a study of the work Historia Naturalis Brasiliae (Natural History of Brazil), authored by Piso and Marcgrave and published in 1648, with main focus on Caatinga of northeast region of Brazil. Focusing the content analysis on the section dedicated to plant species with multiple uses, Marcgrave's contribution to the aforementioned work, this research had the following objectives: the retrieval of 17th century knowledge about the food uses of the flora in the northeast region of Brazil, including the taxonomic classifications; the identification of plant parts, their modes of consumption and the ethnic group of consumers; and the verification of the use of these species over time. The use of 80 food species at the time of the publication of the work is indicated, some of which are endemic to the Caatinga, such as "umbu" (Spondias tuberosa Arruda), "mandacaru" (Cereus jamacaru DC.) and "carnauba" (Copernicia cerifera Mart.). It is noticeable that among the species listed by Marcgrave, some species still lack current studies indicating their real nutritional value. The present study is an unprecedented work because it introduces, in a systematic way, the food plants described in a study of 17th century Brazil. Finally, this study makes information about plants consumed in the past accessible, aiming to provide material for studies that could develop new food products today.

    We present a photometric analysis of 65 galaxies in the rich cluster Abell 1689 at z = 0.183, using the Hubble Space Telescope Advanced Camera for Surveys archive images in the rest-frame V band. We perform two-dimensional multicomponent photometric decomposition of each galaxy adopting different models of the surface-brightness distribution. We present an accurate morphological classification for each of the sample galaxies. For 50 early-type galaxies, we fit both a de Vaucouleurs law and a Sérsic law; S0s are modelled by also including a disc component described by an exponential law. Bars of SB0s are described by the profile of a Ferrers ellipsoid. For the 15 spirals, we model a Sérsic bulge, exponential disc and, when required, a Ferrers bar component. We derive the Fundamental Plane (FP) by fitting 40 early-type galaxies in the sample, using different surface-brightness distributions. We find that the tightest plane is that derived by Sérsic bulges. We find that bulges of spirals lie on the same relation. The FP is better defined by the bulges alone rather than the entire galaxies. Comparison with local samples shows both an offset and rotation in the FP of Abell 1689.

  9. [Laurentius on anatomy].

    PubMed

    Sawai, Tadashi; Sakai, Tatsuo

    2005-03-01

    Andreas Laurentius wrote Opera anatomica (1593) and Historia anatomica (1600). These books were composed of two types of chapters; 'historia' and 'quaestio'. His description is not original, but take from other anatomists. 'Historia' describes the structure, action and usefulness of the body parts clarified after dissection. 'Quaestio' treats those questions which could not be solved only by dissection. Laurentius cited many previous contradicting interpretations to these questions and choose a best interpretation for the individual questions. In most cases, Laurentius preferred Galen's view. Historia anatomica retained almost all the 'historia' and 'quaestio' from Opera anatomica, and added some new 'historia' and 'quaestio', especially in regard to the components of the body, such as ligaments, membranes, vessels, nerves and glands. Other new 'historia' and 'quaestio' in Historia anatomica concerned several topics on anatomy in general to comprehensively analyze the history of anatomy, methods of anatomy, and usefulness of anatomy. Historia anatomica reviewed what was anatomy by describing in 'historia' what was known and in 'quaestio' what was unresolved. Till now Laurentius's anatomical works have attracted little attention because his description contained few original findings and depended on previous books. However, the important fact that Historia anatomica was very popular in the 17th century tells us that people needed non-original and handbook style of this textbook. Historia anatomica is important for further research on the propagation of anatomical knowledge from professional anatomists to non-professionals in the 17th century.

  10. Activation of Two Sequential H-transfers in the Thymidylate Synthase Catalyzed Reaction

    PubMed Central

    2015-01-01

    Thymidylate synthase (TSase) catalyzes the de novo biosynthesis of thymidylate, a precursor for DNA, and is thus an important target for chemotherapeutics and antibiotics. Two sequential C-H bond cleavages catalyzed by TSase are of particular interest: a reversible proton abstraction from the 2′-deoxy-uridylate substrate, followed by an irreversible hydride transfer forming the thymidylate product. QM/MM calculations of the former predicted a mechanism where the abstraction of the proton leads to formation of a novel nucleotide-folate intermediate that is not covalently bound to the enzyme (Wang, Z.; Ferrer, S.; Moliner, V.; Kohen, A. Biochemistry 2013, 52, 2348–2358). Existence of such intermediate would hold promise as a target for a new class of drugs. Calculations of the subsequent hydride transfer predicted a concerted H-transfer and elimination of the enzymatic cysteine (Kanaan, N.; Ferrer, S.; Marti, S.; Garcia-Viloca, M.; Kohen, A.; Moliner, V. J. Am. Chem. Soc. 2011, 133, 6692–6702). A key to both C-H activations is a highly conserved arginine (R166) that stabilizes the transition state of both H-transfers. Here we test these predictions by studying the R166 to lysine mutant of E. coli TSase (R166K) using intrinsic kinetic isotope effects (KIEs) and their temperature dependence to assess effects of the mutation on both chemical steps. The findings confirmed the predictions made by the QM/MM calculations, implicate R166 as an integral component of both reaction coordinates, and thus provide critical support to the nucleotide-folate intermediate as a new target for rational drug design.

Las observaciones fueron realizadas con los telescopios de 1.60-m y 0.60-m del Laboratorio Nacional de Astrofísica, Brasópolis, Brasil. Fueron escogidos diafragmas suficientemente grandes para captar la radiación integrada de cada región HII. Las medidas fueron calibradas por comparación a un conjunto de nebulosas planetarias con flujos absolutos bien definidos. A través de la comparación entre los datos observacionales y modelos evolutivos de WHβ y [0 III] /Hβ (Copetti et al.1986', Astr. and Ap., 156, 111), las edades de las regiones HIl fueron estimadas. Basada en la distribución espacial de las edades de regiones HIl, la historia de la formación estelar reciente en la Pequeña Nube de Magallanes es analizada. La similitud de las medidas de WH&beta y [OIII]/WHβ entre las regiones H II observadas sugiere que hubo una explosión de formación estelar a 4±1 x106 años en la Pequeña Nube de Magallanes.

  17. The determinants of response time in a repeated constant-sum game: A robust Bayesian hierarchical dual-process model.

    PubMed

    Spiliopoulos, Leonidas

    2018-03-01

    The investigation of response time and behavior has a long tradition in cognitive psychology, particularly for non-strategic decision-making. Recently, experimental economists have also studied response time in strategic interactions, but with an emphasis on either one-shot games or repeated social-dilemmas. I investigate the determinants of response time in a repeated (pure-conflict) game, admitting a unique mixed strategy Nash equilibrium, with fixed partner matching. Response times depend upon the interaction of two decision models embedded in a dual-process framework (Achtziger and Alós-Ferrer, 2014; Alós-Ferrer, 2016). The first decision model is the commonly used win-stay/lose-shift heuristic and the second the pattern-detecting reinforcement learning model in Spiliopoulos (2013b). The former is less complex and can be executed more quickly than the latter. As predicted, conflict between these two models (i.e., each one recommending a different course of action) led to longer response times than cases without conflict. The dual-process framework makes other qualitative response time predictions arising from the interaction between the existence (or not) of conflict and which one of the two decision models the chosen action is consistent with-these were broadly verified by the data. Other determinants of RT were hypothesized on the basis of existing theory and tested empirically. Response times were strongly dependent on the actions chosen by both players in the previous rounds and the resulting outcomes. Specifically, response time was shortest after a win in the previous round where the maximum possible payoff was obtained; response time after losses was significantly longer. Strongly auto-correlated behavior (regardless of its sign) was also associated with longer response times. I conclude that, similar to other tasks, there is a strong coupling in repeated games between behavior and RT, which can be exploited to further our understanding of decision

    There are an increasing number of researches in science education that affirm the importance of discussions on the "nature of science" in basic education level as well as in teacher training. The history of science applied to education is a way to contextualize epistemological discussions, allowing both the understanding of scientific content and learning about science concepts. We present some reasonably consensual definitions on the nature of science that have been widely discussed by the academic community. We show also some episodes in the history of astronomy which can lead to discussions involving some aspects of the nature of science, and how they can do it.

    The objective of this study was to validate (SANCO/12495/2011 and NTC-ISO/IEC 17025) multi-residue multi-class methods using QuEChERS sample preparation and GC-MS for the analysis of regulated pesticides in tomatoes (Solanum lycopersicum), tamarillos (Solanum betaceum) and goldenberries (Physalis peruviana). These Latin American products are representative and widely produced in Antioquia (Colombia). Sample preparation followed the UNE-EN 15662 method (150 mg MgSO4, 25mg primary secondary amines and 25mg of octadecylsiloxane for cleanup; graphitized carbon black was added for tomatoes). Extracts were injected using a programmed temperature-vaporizing injector. The residues were validated over a range from 0.02 mg/kg to 0.20 mg/kg, with 24 analytes validated in tomatoes, 33 in tamarillos and 28 in goldenberries. An initial risk assessment was enabled by monitoring 24 samples in the municipalities of El Peñol, Marinilla and San Vicente Ferrer. Risks were found for tomatoes, but no significant risks were found for tamarillos or goldenberries. Copyright © 2014 Elsevier Ltd. All rights reserved.

  5. HISTORIA Alexandri Magni: Astronomy, Astrology and Tradition

    NASA Astrophysics Data System (ADS)

    Papathanassiou, M.

    A popular text on the birth, life and death of Alexander the Great is that attributed to Pseudo-Callisthenes. According to this Byzantine text Alexander is the son of the last king of Egypt, the Pharao Nectanebo, who left his country and following Apollo's oracle visited Macedonia. Nectanebo was famous for his astronomical, astrological and magical knowledge which he used to prevent Alexander's birth for some hours until a favoured time comes. In only one manuscript (Paris. gr. 1711, 11th century) of this work there is a unique passage in which astronomical information is given regarding the positions of the Sun, the Moon, and the five planets at the time of Alexander's birth. In this paper I attempt a study of all information related to the astronomical instruments and their use as mentioned in the text as well as of the astronomical information regarding Alexander's birth.

    Introducción Medio Ambiente y Cáncer Pediátrico (CP) en la Región de Murcia (RM) es un proyecto de investigación, cuya principal meta es el desarrollo de una cuidadosa historia ambiental pediátrica (HAP) y el uso de sistemas de información geográfica (SIG) para crear mapas de incidencia y analizar la distribución geográfica del CP en la RM. El objetivo es presentar la metodología, el estudio descriptivo y los primeros resultados sobre la incidencia espacial y temporal del CP en la RM (España). Material y métodos Estudio descriptivo y de georreferenciación de todos los casos de CP menores de 15 años, diagnosticados entre el 1 de enero de 1998 y el 31 de diciembre de 2009. Se han asociado a cada caso tres direcciones postales, durante el embarazo, en el período posnatal y en el momento del diagnóstico. También se han utilizado las siguientes variables: sexo, fechas de nacimiento y diagnóstico y el diagnóstico patológico. Resultados No se observa un incremento en la tendencia de la incidencia del CP. La tasa cruda de incidencia fue de 14,3 casos por 100.000 niños menores de 15 años. La razón de incidencia estandarizada es más elevada en el noroeste de la RM. El 30% tienen un domicilio previo al diagnóstico distinto al del embarazo. Conclusiones La integración de la información temporal y espacial de la HAP en un SIG permitirá la identificación y el estudio de conglomerados espacio-temporales a través de un sistema de vigilancia medioambiental que ayude a ponderar la importancia de los factores de riesgo asociados.

  7. Francis Bacon: constructing natural histories of the invisible.

    PubMed

    Rusu, Doina-Cristina

    2012-01-01

    The natural histories contained in Francis Bacon's Historia naturalis et experimentalis seem to differ from the model presented in De augmentis scientiarum and the Descriptio globi intellectualis in that they are focused on the defining properties of matter, its primary schematisms and the spirits. In this respect, they are highly speculative. In this paper I aim to describe the Historia naturalis et experimentalis as a text about matter theory, the histories of which are ascending from what is most evident to the senses to what is least accessible to them. Moreover, the Latin natural histories are parts of a methodological procedure in which the provisional rules and axioms obtained in one history can be used as theoretical assumptions for another history, thereby permitting one to delve ever more profoundly into the structure of nature.

  9. Attending to insects: Francis Willughby and John Ray

    PubMed Central

    2012-01-01

    Francis Willughby and John Ray were at the forefront of the natural history of insects in the second half of the seventeenth century. Willughby in particular had a deep interest in insects' metamorphosis, behaviour and diversity, an interest that he passed on to his friend and mentor Ray. By examining Willughby's contributions to John Wilkins's Essay towards a Real Character (1668) and Ray's Methodus insectorum (1705) and Historia insectorum (1710), which contained substantial material from Willughby's manuscript history of insects, one may reconstruct how the two naturalists studied insects, their innovative use of metamorphosis in insect classification, and the sheer diversity of insect forms that they described on the basis of their own collections and those of London and Oxford virtuosi. Imperfect as it was, Historia insectorum was recognized by contemporaries as a significant contribution to the emerging field of entomology.

    PubMed

    Niklas, Karl J; Cobb, Edward D

    2017-09-11

    The study of organic form has a long and distinguished history going at least as far back as Aristotle's Historia Anima¯lium, wherein he identified five basic biological processes that define the forms of animals (metabolism, temperature regulation, information processing, embryo development, and inheritance). Unfortunately, all of Aristotle's writings about plant forms are lost. We know of them only indirectly from his student Theophrastus's companion books, collectively called Historia Plantarum, wherein plant forms are categorized into annual herbs, herbaceous perennials, shrubs, and trees. The study of plant forms did not truly begin until the romantic poet and naturalist Goethe proposed the concept of a hypothetical 'Plant Archetype', declared "Alles ist Blatt", and first coined the word morphologie, which inspired the French anatomist Cuvier (who established the field of comparative morphology), the English naturalist Darwin (who saw his theory of evolution reinforced by it), and the Scottish mathematician D'Arcy Thompson (who attempted to quantify it).

    PubMed

    Brown, Robin S

    2017-04-01

    Introducing the 'participatory' paradigm associated with the work of transpersonalists Richard Tarnas and Jorge Ferrer, the author outlines an approach to Jung's archetypal thinking that might offer a more adequate basis in which to ground a non-reductive approach to practice. In order to demonstrate the relevance of this outlook at the present time, the author begins by examining recent debates concerning the nature of 'truth' in the clinical setting. Reflecting on the difficulties analysts face in attempting to maintain professional authority without falling into an implicit authoritarianism, it is argued that any approach to therapy seeking to orient itself towards 'the unconscious' must posit the challenges of pluralism as a central concern for practice. With reference to the relationship between analytical psychology and the psychoanalytic mainstream, attention is drawn to the theoretical problems raised by the relational commitment to constructivist epistemologies, and a consequent tendency towards biological reductionism. Turning to the Jungian literature, similar tensions are observed at play in the present state of analytical psychology. Drawing attention to the process-oriented qualities of Jung's work, it is suggested that the speculative nature of Jung's psychology offers a more adequate basis for contemporary practice than might be assumed. © 2017, The Society of Analytical Psychology.

  19. Profiler - A Fast and Versatile New Program for Decomposing Galaxy Light Profiles

    NASA Astrophysics Data System (ADS)

    Ciambur, Bogdan C.

    2016-12-01

    I introduce Profiler, a user-friendly program designed to analyse the radial surface brightness profiles of galaxies. With an intuitive graphical user interface, Profiler can accurately model galaxies of a broad range of morphological types, with various parametric functions routinely employed in the field (Sérsic, core-Sérsic, exponential, Gaussian, Moffat, and Ferrers). In addition to these, Profiler can employ the broken exponential model for disc truncations or anti-truncations, and two special cases of the edge-on disc model: along the disc's major or minor axis. The convolution of (circular or elliptical) models with the point spread function is performed in 2D, and offers a choice between Gaussian, Moffat or a user-provided profile for the point spread function. Profiler is optimised to work with galaxy light profiles obtained from isophotal measurements, which allow for radial gradients in the geometric parameters of the isophotes, and are thus often better at capturing the total light than 2D image-fitting programs. Additionally, the 1D approach is generally less computationally expensive and more stable. I demonstrate Profiler's features by decomposing three case-study galaxies: the cored elliptical galaxy NGC 3348, the nucleated dwarf Seyfert I galaxy Pox 52, and NGC 2549, a double-barred galaxy with an edge-on, truncated disc.

  6. La historia orbital de Deimos y la oblicuidad de Marte

    NASA Astrophysics Data System (ADS)

    Brunini, A.; Yokoyama, T.

    Recientemente, se ha demostrado mediante extensas integraciones numéricas, que la rotación de Marte pasó repetidamente por estados caóticos de movimiento, debido al pasaje por zonas de resonancia spin - órbita. En dichas circunstancias, la oblicuidad marciana pudo haber sufrido grandes excursiones de varias decenas de grados. Las consecuencias de dichas variaciones son de extrema importancia en el contexto de la búsqueda de manifestaciones de vida fósil en dicho planeta. El estudio de la dinámica orbital del satélite más exterior de Marte, Deimos, nos ha permitido comprobar, en el marco de las distintas teorías sobre su orígen, que la oblicuidad de Marte dificilmente pudo haber sufrido variaciones que la aparten más de 10o respecto de actual valor. Este resultado parece ser mucho más robusto que las simulaciones numéricas de Touma y Wisdom asi como las de Laskar y Robutel, lo que permite poner cotas más severas a la evolución paleoclimática de Marte.

    Este folleto contiene historias veridicas que ilustran como sobrevivir, y como no sobrevivir, a un tsunami. Esta publicacion esta dirigida a las personas que viven, trabajan o, simplemente, se divierten a lo largo de las costas que pueden ser afectadas por un tsunami. Tales costas rodean la mayor parte del Oceano Pacifico pero tambien incluyen algunas areas costeras de los Oceanos Atlantico e Indico. Aunque mucha gente llama a los tsunamis 'olas de marea', estos no estan relacionados a las mareas, sino son una serie de olas, o 'tren de olas', generalmente causadas por cambios en el nivel del fondo marino durante los terremotos. Los tsunamis tambien pueden ser generados por la erupcion de volcanes costeros, islas volconicas, deslizamientos submarinos e impactos de grandes meteoritos en el mar. Como sucedio en Sumatra en el 2004, los tsunamis pueden alcanzar alturas de 15 metros, no tan solo en la costa sino tambien kilometros tierra adentro. Los relatos presentados en este folleto fueron seleccionados de entrevistas realizadas a personas que sobrevivieron al tsunami del Oceano Pacifico de 1960. Muchas de estas personas, incluyendo a la enfermera de la foto, se enfrento a las olas generadas a poca distancia, en la costa chilena. En cambio, otros debieron hacer frente al tsunami muchas horas despues, en Hawai y Japon. La mayoria de las entrevistas fueron realizadas a fines de los anos ochenta y en los noventa. Las historias ofrecen una mezcla de lecciones de supervivencia a un tsunami. En algunos casos se presentan las acciones que confiablemente salvaron vidas: poner atencion a los avisos de la naturaleza, abandonar los bienes, dirigirse rapidamente a un sector alto y permanecer alli hasta que el tsunami realmente haya terminado. Otras historias describen como se encontro refugio al subir a construcciones y arboles o flotar sobre desechos, tacticas que tuvieron diferentes resultados y que pueden ser recomendadas solo como actos desesperados de personas atrapadas en

  8. The pancreas from Aristotle to Galen.

    The first description of the pancreas in literature is found in Aristotle's Historia Animalium, but it is modified by "so-called". Therefore, the origin is pursued more extensively. The Greek-English Lexicon recommends three treatises as a possible original source. These three and Galen's other papers are investigated. In 2005, Sachs et al. suggested an origin of the pancreas might have derived from the intestinal divination using the avian pancreas. This report is evaluated. The avian pancreas which is the intraperitoneal organ, might have been well known by the intestinal divination, and people have called the organ pankreas or kallikreas. Anatomical dissection on human body was not accepted before the Aristotle's time. "So-called pancreas" in Historia must have been interpolated by Theophrastus. He was the most faithful and reliable disciple of Aristotle and succeeded the Aristotle's school. He and Macedonian ruler of Egypt Ptolemy I had known each other and there had been a strong link between them. The contemporary Herophilus performed many public dissections on both human and animal bodies in Alexandria. He named the various parts of the human body and designated the beginning intestine as duodenum. Yet in his extant works, the pancreas is not found. It is surmised that Herophilus may be the first to recognize the human pancreas, which is fixed with retroperitoneal tissue, and he named it "so-called pancreas". Theophrastus might have interpolated Herophilus' designation in Historia Animalium. Galen also uses "so-called pancreas" to designate the human pancreas. Galen's descriptions, that is, "Nature created 'so-called pancreas 'and spread it beneath all vessels" are not generally acceptable but propose the very rare portal vein anomalies. Since the early years of the 20th century, cases with a preduodenal portal vein or a prepancreatic portal vein have been reported. Although the incidence is very rare, its surgical importance is emphasized. Copyright © 2014

    Introduction Supplementation of Omega-3 fatty acids (n-3FA) in athletes is related to the anti-inflammatory and/or antioxidant effect and consequently its action on all the processes of tissue restoration and adaptation to physical stress. Objective Evaluate the Omega-3 Index (O3Ix) response, in red blood cells, to supplemental EPA + DHA intake in the form of high purity and stable composition gums (G), in elite summer athletes. Method Twenty-four summer sport athletes of both sexes, pertaining to the Olympic Training Center in Spain, were randomized to two groups (2G = 760 or 3G = 1140 mg of n-3 FA in Omegafort OKids, Ferrer Intl.) for 4 months. Five athletes and four training staff volunteers were control group. Results The O3Ix was lower than 8% in 93.1% of all the athletes. The supplementation worked in a dose-dependent manner: 144% for the 3G dose and 135% for the 2G, both p < 0.001, with a 3% significant decrease of Omega-6 FAs. No changes were observed for the control group. Conclusions Supplementation with n-3FA increases the content of EPA DHA in the red blood cells at 4 months in a dose-dependent manner. Athletes with lower basal O3Ix were more prone to increment their levels. The study is registered with Protocol Registration and Results System (ClinicalTrials.gov) number NCT02610270. PMID:28656110

    Studying of efficiency of the combined application of the citicoline possessing nootropic and anticonvulsive action and antiepileptic drug of diazepam on the acute generalized convulsions (AGC) caused by a convulsant pentylentetrazole (PTZ). Experiments are executed on the male Wistar rats (n = 68) weighing 160-190 g on the AGС model caused by of PTZ in a dose of 80 mg/kg, intraperitoneally (i.p.). For studying of efficiency of the combined use of drugs determined the minimum anticonvulsive action of a citicoline (Tserakson, «Nicomed Ferrer Internacional, S.A.») and diazepam (Relanium, Warsaw pharmaceutical plant of Polf AO, Warsaw, Poland). For this citicoline were administered i.p. in doses 500 and 300 mg/kg 1 hour before the PTZ and diazepam - in doses of 0,5 and 0,25 mg/kg 30 min before administration of PTZ. Control animals were injected with saline to the same extent and under the same experimental conditions. It is shown that the combined administration of a citicoline and diazepam in minimum active doses (300 and 0.25 mg/kg respectively), increases anticonvulsive properties of both drugs. The combined administration of citicoline with diazepam in minimally active doses enhances anticonvulsant properties of both drugs, thereby reducing the risk of development of side effects. In addition, the research may serve as experimental justification for the use of drugs in case of convulsions for the purpose beneficial effect on cognitive function and delays of progressing of neurodegenerative processes.

    In 1712 Martin Lister bequeathed the collection of more than 1000 copperplates to the University of Oxford that he used for his Historiae Conchyliorum, the first comprehensive study of conchology. In the mid-eighteenth century, William Huddesford, keeper of the Bodleian Library, used the copperplates to create another edition of Historiae, but after that they are not mentioned again in the published literature. I recently 'rediscovered' the plates in the Bodleian Library, since their transfer from the Ashmolean Museum in 1860. I use historical analysis, as well as a selective study of the copperplates with X-ray fluorescence techniques, to examine a portion of the plates and the process of their production. I show that Martin Lister's daughter engraved a paper for Philosophical Transactions, and demonstrate that she was among the first female scientific illustrators to use a microscope. Furthermore, one of the Lister copperplates may be the last survivor of those engraved for Philosophical Transactions, the rest having been surrendered to the nation in World War I. The significant intellectual and artisanal challenges presented to a skilful naturalist in the transformation of a field specimen into an aesthetically pleasing illustration as well as a scientific object conveying taxonomic information are delineated.

    Over a long period of time, particularly from the nineteenth century on, Francis Bacon's philosophy has been interpreted as centred on the Novum organum and focused on the role that a well-organized method may play in securing a reliable knowledge of nature. In fact, if we examine Bacon's oeuvre as a whole, including some recent manuscript findings (De vijs mortis), we can safely argue that the issues addressed in the Novum organum represent only a part of Bacon's agenda, and not even the most important ones. By contrast, it is apparent that, from the very beginning of his investigations, he emphasized the central role of medicine, the need to establish new approaches in the study of the vital functions and the importance of promoting new discoveries in the medical field, not so much to find a cure for the many illnesses that plagued mankind as to prolong human life. In this sense, Historia vitae et mortis plays a central role in Bacon's programme to extend human knowledge and power, for, in his opinion, human beings could recover their lost ability to live a long and healthy life by embarking on careful investigations of nature. Far from being a purely descriptive or abstract exercise, Bacon's historia can therefore be seen as an operative tool to attain some of mankind's basic aims.

    Thomasen, A L

    1980-12-01

    In her essay the author pictures the dominating role of Aristotle's doctrines as compared with the more progressive scientific achievements of the Alexandrian school of medicine during the Middle Ages. One of the consequences of this dominance was an almost total neglect of the special health problems of women who were-in contrast with men and according to the Aristotelian tradition of the Middle Ages-considered to be defective human beings: a nearly uneradicable opinion far into later centuries. In addition it was not only in accordance with Christian doctrines but with religious and social conceptions and habits of the Arabic tradition as well. The progressive efforts of some reasonable medieval physicians to improve the deplorable position of women were incapable to break through the bulwark of cooperating misjudgments and prejudices. It took a lot of time-from Hippocrates to Galen and the Arabs-and many errors were made till the teachings of Soranos of Ephesos, the first great gynaecologist, began to gain ground since the late Middle Ages, when his treatment of women's diseases and obstetrical instructions slowly prevailed the speculative perceptions of Aristotle and his epigones.

    Historians and physicians have different social vantage points and have developed widely different professional cultures. This diversity is a distinct feature of their research, their theoretical approaches, and their scholarly methods. The historian's and the physician's points of view both seem to be necessary parts of medical history. The subject itself as well as the scholars involved may profit from teamwork. The author also asks whether historical knowledge in the field of medicine is useful for today's practitioners. Her answer is yes. Historical insight might contribute to a better understanding of day-to-day problems and the complex structures of which physicians are part. Furthermore, it is suggested that physicians will benefit from insights into why their discipline and their professional position have developed in the ways they have. At its best, historical knowledge can contribute to a deeper understanding of the limitations of medicine, and so may add to physicians' ability to adjust their role in line with the present time. Historical knowledge might even contribute to increased respect for other branches of knowledge and for other people's skills and professional problems.

    We present photometry and long-slit spectroscopy for 12 S0 and spiral galaxies selected from the Catalogue of Isolated Galaxies. The structural parameters of the sample galaxies are derived from the Sloan Digital Sky Survey I-band images by performing a two-dimensional photometric decomposition of the surface brightness distribution. This is assumed to be the sum of the contribution of a Sérsic bulge, an exponential disc, and a Ferrers bar characterized by elliptical and concentric isophotes with constant ellipticity and position angles. The rotation curves and velocity dispersion profiles of the stellar component are measured from the spectra obtained along the major axis of galaxies. The radial profiles of the Hβ, Mg and Fe line-strength indices are derived too. Correlations between the central values of the Mg2 and line-strength indices and the velocity dispersion are found. The mean age, total metallicity and total α/Fe enhancement of the stellar population in the centre and at the radius, where the bulge gives the same contribution to the total surface brightness as the remaining components, are obtained using stellar population models with variable element abundance ratios. We identify intermediate-age bulges with solar metallicity and old bulges with a large spread in metallicity. Most of the sample bulges display supersolar α/Fe enhancement, no gradient in age and negative gradients of metallicity and α/Fe enhancement. These findings support a formation scenario via dissipative collapse where environmental effects are remarkably less important than in the assembly of bulges of galaxies in groups and clusters.

    1997-03-01

    In the last several years, there have been continuing efforts to probe long-ranged magnetic order at surfaces by x-ray and neutron diffraction, following many earlier studies by low energy electron diffraction. The main motivation has been to discover how bulk magnetic structures are modified near a surface, where the crystal symmetry is broken. In this talk, we describe x-ray scattering studies of the magnetic structure observed near the (001) surface of the antiferromagnet uranium dioxide.(G. M. Watson, Doon Gibbs, G. H. Lander, B. D. Gaulin, L.E. Berman, Hj. Matzke and W. Ellis, Phys. Rev. Lett. 77), 751 (1996). Within about 50 Åof the surface, the intensity of the magnetic scattering decreases continuously as the bulk Neel temperature is approached from below. This contrasts with the bulk magnetic ordering transition which is discontinuous. Recent measurements of the specular magnetic reflectivity suggest that the width of the magnetic interface diverges as a power-law in reduced temperature reminiscent of surface induced disorder. Related experiments concerned with magnetic crystallography of Co_3-Pt(111) surfaces(S. Ferrer, P. Fajardo, F. de Bergevin, J. Alvarez, X. Torrelles, H. A. van der Vegt and V. H. Etgens, Phys. Rev.

    When then president José Figueres Ferrer invited the world to use Costa Rica as a "laboratory for sustainable development" in 1997, the country's fame as a biodiversity mecca was firmly established. Yet despite vast investment, conservation-related interventions in the cantons of Osa and Golfito along the country's southern Pacific coast have been seen as overly conservation-oriented and carried out "with its back to the communities." By ignoring human well-being, these interventions have been unable to overcome the region's vast disparities in access to resources and general state of underdevelopment despite investments of many millions of dollars in recent decades. With the country's third international airport and Central America's largest hydroelectric project proposed for the region, as well as other infrastructure-driven development currently underway, the region is poised to undergo rapid change. This presentation first describes the Osa-Golfito Initiative (INOGO), an interdisciplinary effort facilitated by the Stanford Woods Institute for the Environment to development a long term strategic action plan that ensures a development trajectory focused on human and environmental well-being. Whereas a concurrent presentation will focus on biophysical components of INOGO, the focus here is on the often-overlooked contributions of social science for ensuring the region's future sustainability. An anthropological approach is taken to assess the assets and resources of the region's residents, and the obstacles and challenges as they perceive them. This groundwork provides a crucial link between individual and local realities, and the regional and national political economy, and thus provides greater probability of sustainable development occurring with its "face to the communities.";

    Atrial and ventricular tachyarrhythmias can be perpetuated by up-regulation of inward rectifier potassium channels. Thus, it may be beneficial to block inward rectifier channels under conditions in which their function becomes arrhythmogenic (e.g., inherited gain-of-function mutation channelopathies, ischemia, and chronic and vagally mediated atrial fibrillation). We hypothesize that the antimalarial quinoline chloroquine exerts potent antiarrhythmic effects by interacting with the cytoplasmic domains of Kir2.1 (IK1), Kir3.1 (IKACh), or Kir6.2 (IKATP) and reducing inward rectifier potassium currents. In isolated hearts of three different mammalian species, intracoronary chloroquine perfusion reduced fibrillatory frequency (atrial or ventricular), and effectively terminated the arrhythmia with resumption of sinus rhythm. In patch-clamp experiments chloroquine blocked IK1, IKACh, and IKATP. Comparative molecular modeling and ligand docking of chloroquine in the intracellular domains of Kir2.1, Kir3.1, and Kir6.2 suggested that chloroquine blocks or reduces potassium flow by interacting with negatively charged amino acids facing the ion permeation vestibule of the channel in question. These results open a novel path toward discovering antiarrhythmic pharmacophores that target specific residues of the cytoplasmic domain of inward rectifier potassium channels.—Noujaim, S.

In order to preserve life, it is necessary to investigate various kinds of generation, notably, those which occurr without seeds. The study of putrefaction is also crucial for the prolongation of life.

    Vega Osorio, Melba

    The purpose of this research was to capture the memories, practices, thoughts and philosophies of education that four experienced Science teachers have accumulated through the years. The life story qualitative research design was used in order to collect more meaningful information from the participants amenable to in depth analysis and interpretation. The life stories interviews were conducted using an interview protocol especially designed for the study. The interviews were recorded and transcribed. The questions that guided this research are: 1. What are the meanings that science teachers give to their educational practices? 2. How did the life experiences of the participants contribute to their success as science teachers? 3. How did the participants' educational practices change and evolve over time? 4. What does teaching science mean in the life of the participants? 5. Which reflections arise from the work of the participants that impact the teaching of science? 6. What are the participants' conceptions about teachers' professional development? 7. What are the participants' contributions to the field of scientific education? Wolcott's (1994) DAI analytical model was used for the analysis of the information and the narratives were written following the three dimensions of the model: description, analysis and interpretation. According to the life stories of the participants, being a teacher requires more than teaching the content. To be a successful and an exemplary science teacher, they have to live the teaching vocation, with dedication, passion, commitment and love for teaching, for students and science; teachers have to give their best for the students, even if it means making personal sacrifices; they should keep updated in knowledge (content) and in educational innovations (strategies); emphasizing both the theoretical and the practical aspects in the field of science, and being an inspirational guide for students.

    The hypothesis of the prenatal programming of adult diseases took on increasing interest from the moment that, in the 60s, an epidemiological association was proposed between low birth weight and cardiovascular diseases. In the last 20 years it has been demonstrated that individuals with low weight, low stature and thinness at birth have a higher risk of developing cardiovascular diseases and type 2 diabetes. Animal and clinical studies are casting light on the biological mechanisms underlying the association between modified development in the uterus and diseases, and on how growth in adolescence and in adult life can modulate this initial proneness to disease. One of the mechanisms that has aroused most interest among researchers is the reduced number of nephrons, associated with low birth weight, which predisposes to glomerulosclerosis and increased systemic arterial pressure in adult life. A correlation has also been found between low weight at birth and peripheral resistance to insulin. Nevertheless, it is thought that modified prenatal development is only a predisposing factor, open to profound influences in the course of postnatal development. It has in fact been demonstrated that accelerated development in the period of infancy and adolescence can extend the initial condition of neonatal suffering. Indirectly these studies renew and at the same time extend the concept of prevention, a priority aim of the physician of the third millennium.

    The first step from the neuropsychology in Argentina was in 1883 with the thesis of Antonio Piñeiro about the brain localization of the language and vision disorders, only few years after Broca. The aim of this work has been to describe the development of the neuropsychology in Argentina and its relation with the psychology, neurology and psychiatry. The first period was into the neurology with its French school in?uence. In 1907, Jose Ingeniero published in French his book about "amusia", Cristofredo Jakob the "folia neurobiologica" where he described the organization of the human brain, Vicente Dimitri in 1933 his book "aphasia" and Bernardo de Quiros in 1959 his works about dyslexia. The psychiatry at the hospices with the German influence from Jakob developed to the modern neuropsychiatry with Juan Carlos Goldar. The argentine school of psychology by the holism and the psychoanalysis influence do not accept the neuropsychology until 1960 where was included at the school of psychology from the university of Buenos Aires (UBA) with the first linguistics works of Juan Azcoaga. At the 80, began the North American influence of the neurology with authors like Carlos Mangone (dementia), Ramon Leiguarda (apraxia), Sergio Starkstein (depression and apathy) and Ricardo Allegri (memory and Alzheimer). In 1982 the Argentine Neuropsychological Society was founded and in 1987 was the working group of dementia from the Argentine Neurological Society. At this moment, Aldo Ferreres organized the chair of neuropsychology at the school of psychology (UBA). Nowadays, the growing as discipline is in context of the psychology, neurology and psychiatry in the way of the recent cognitive neurosciences.

    'Number rules the universe.' The Pythagoras 'If you wish to forsee the future of mathematics our course is to study the history and present conditions of the science.' Henri Poincaré 'The primary source (Urqell) of all mathematics are integers.' Hermann Minkowski This paper is written to commemorate the centennial anniversary of the Mathematical Association of America. It deals with a short history of different kinds of natural numbers including triangular, square, pentagonal, hexagonal and k-gonal numbers, and their simple properties and their geometrical representations. Included are Euclid's and Pythagorean's main contributions to elementary number theory with the main contents of the Euclid Elements of the 13-volume masterpiece of mathematical work. This is followed by Euler's new discovery of the additive number theory based on partitions of numbers. Special attention is given to many examples, Euler's theorems on partitions of numbers with geometrical representations of Ferrers' graphs, Young's diagrams, Lagrange's four-square theorem and the celebrated Waring problem. Included are Euler's generating functions for the partitions of numbers, Euler's pentagonal number theorem, Gauss' triangular and square number theorems and the Jacobi triple product identity. Applications of the theory of partitions of numbers to different statistics such as the Bose- Einstein, Fermi- Dirac, Gentile, and Maxwell- Boltzmann statistics are briefly discussed. Special attention is given to pedagogical information through historical approach to number theory so that students and teachers at the school, college and university levels can become familiar with the basic concepts of partitions of numbers, partition functions and their modern applications, and can pursue advanced study and research in analytical and computational number theory.

    This study examined how children (9 years), adolescents (13 to 15 years), younger adults (21 to 26 years), and older adults (70 to 76 years) chart age gradients of cognitive and social functioning from childhood to old age. Participants (N = 156) rated typical performance levels in different life phases for 10 aspects of cognitive and social functioning. Compared with older participants, children expected lower performance levels and higher temporal stability, particularly during adulthood and into old age, and showed lower interindividual consensus in their ratings. Individuals in all 4 age groups recognized that fluid cognitive abilities reach their developmental peak earlier in life and decline more steeply thereafter than crystallized cognitive abilities. Older adults and, to a lesser extent, children evaluated their own current functioning as being better than that of their typical age peers. Furthermore, older adults charted typical cognitive development in middle and earlier late adulthood more positively than the participants in the other 3 age groups, which possibly reflects a partial externalization of their own positive self-views and a self-enhancing bias. Comparisons with life span gradients of cognitive performance (McArdle, Ferrer-Caja, Hamagami, & Woodcock, 2002) suggest that the ratings of adolescents and younger adults were in better agreement with empirically observed average performance trajectories than the ratings of children and older adults. We conclude that beliefs about normative cognitive and social aspects of life span development emerge in late middle childhood, solidify into culturally shared scripts by mid-adolescence, and remain subject to further change into old age.

    We present PROFIT, a new code for Bayesian two-dimensional photometric galaxy profile modelling. PROFIT consists of a low-level C++ library (libprofit), accessible via a command-line interface and documented API, along with high-level R (PROFIT) and PYTHON (PyProFit) interfaces (available at github.com/ICRAR/libprofit, github.com/ICRAR/ProFit, and github.com/ICRAR/pyprofit, respectively). R PROFIT is also available pre-built from CRAN; however, this version will be slightly behind the latest GitHub version. libprofit offers fast and accurate two-dimensional integration for a useful number of profiles, including Sérsic, Core-Sérsic, broken-exponential, Ferrer, Moffat, empirical King, point-source, and sky, with a simple mechanism for adding new profiles. We show detailed comparisons between libprofit and GALFIT. libprofit is both faster and more accurate than GALFIT at integrating the ubiquitous Sérsic profile for the most common values of the Sérsic index n (0.5 < n < 8). The high-level fitting code PROFIT is tested on a sample of galaxies with both SDSS and deeper KiDS imaging. We find good agreement in the fit parameters, with larger scatter in best-fitting parameters from fitting images from different sources (SDSS versus KiDS) than from using different codes (PROFIT versus GALFIT). A large suite of Monte Carlo-simulated images are used to assess prospects for automated bulge-disc decomposition with PROFIT on SDSS, KiDS, and future LSST imaging. We find that the biggest increases in fit quality come from moving from SDSS- to KiDS-quality data, with less significant gains moving from KiDS to LSST.

    -dimensional isopotential surfaces -- we discuss the viability of this assumption for NGC 720. Milgrom's Modification of Newtonian Dynamics (MOND) cannot dispel this manifestation of dark matter. Hence, geometrical considerations require, without mention of pressure or temperature, the presence of an extended, massive dark matter halo in NGC 720. Employing essentially the technique of Buote & Canizares (1992; Buote 1992) we use the shape of the X-ray surface brightness to constrain the shape of the total gravitating matter. The total matter is modeled as either an oblate or prolate spheriod of constant shape and orientation having either a Ferrers (rho approximately r(exp -n)) or Hernquist density. Assuming the X-ray gas is in hydrostatic equilibrium, we construct a model X-ray gas distribution for various temperature profiles. We determine the ellipticity of the total gravitating matter to be epsilon approximately 0.50-0.70. Using the single-temperature model we estimate a total mass approximately (0.41-1.4) x 10(exp 12) h(sub 80) solar mass interior to the ellipsoid of semimajor axis 43.6 h(sub 80) kpc. Ferrers densities as steep as r(exp -3) do not fit the data, but the r(exp -2) and Hernquist models yield excellent fits. We estimate the mass distributions of the stars and the gas and fit the dark matter directly. For a given gas equation of state and functional forms for the visible stars, gas, and dark matter, these models yield a distance-independent and temperature-independent measurement of the ratio of dark mass to stellar mass M(sub DM)/M(sub stars). We estimate a minimum M(sub DM)/M(sub stars) greater than or equal to 4 which corresponds to a total mass slightly greater than that derived from the single-temperature models for distance D = 20h(sub 80) Mpc.

    2007-01-01

    Plant monofunctional aspartate kinase is unique among all aspartate kinases, showing synergistic inhibition by lysine and S-adenosyl-l-methionine (SAM). The Arabidopsis genome contains three genes for monofunctional aspartate kinases. We show that aspartate kinase 2 and aspartate kinase 3 are inhibited only by lysine, and that aspartate kinase 1 is inhibited in a synergistic manner by lysine and SAM. In the absence of SAM, aspartate kinase 1 displayed low apparent affinity for lysine compared to aspartate kinase 2 and aspartate kinase 3. In the presence of SAM, the apparent affinity of aspartate kinase 1 for lysine increased considerably, with K(0.5) values for lysine inhibition similar to those of aspartate kinase 2 and aspartate kinase 3. For all three enzymes, the inhibition resulted from an increase in the apparent K(m) values for the substrates ATP and aspartate. The mechanism of aspartate kinase 1 synergistic inhibition was characterized. Inhibition by lysine alone was fast, whereas synergistic inhibition by lysine plus SAM was very slow. SAM by itself had no effect on the enzyme activity, in accordance with equilibrium binding analyses indicating that SAM binding to aspartate kinase 1 requires prior binding of lysine. The three-dimensional structure of the aspartate kinase 1-Lys-SAM complex has been solved [Mas-Droux C, Curien G, Robert-Genthon M, Laurencin M, Ferrer JL & Dumas R (2006) Plant Cell18, 1681-1692]. Taken together, the data suggest that, upon binding to the inactive aspartate kinase 1-Lys complex, SAM promotes a slow conformational transition leading to formation of a stable aspartate kinase 1-Lys-SAM complex. The increase in aspartate kinase 1 apparent affinity for lysine in the presence of SAM thus results from the displacement of the unfavorable equilibrium between aspartate kinase 1 and aspartate kinase 1-Lys towards the inactive form.

    This paper analyses passages of the Hippocratic Corpus, of Aristotle and Galen about oneirogmòs, spermatic emission during sleep, referring specifically to women. Into the Hippocratic texts there is only one gynaecological case among many cases about males: for them this nocturnal emission is symptom of dangerous illness and De genitura gives a causal explanation of such phaenomenon. Instead, in Aristotle and Galen erotic dream is evidence for or against emission of female seed and female contribution to generation. As the argument ofHistoria animalium book X shows clear theoretical differences from that of De generatione animalium, the topic of erotic dream also concerns issues of authenticity.

    The central question of stereotaxic radiosurgery in acoustic neurinomas is how to pinpoint its main objective: is it a better alternative to neurosurgery or an option when surgery is unfeasible? This study is a continuation of the article published in 1995 in Acta Neurochirurgica, but benefits from greater experience, more complete analysis and longer supervision of results. The conclusions that can be drawn to date from our own findings and from others in the literature are the following: radiosurgery can be used not only to prevent neurinoma growth and at the same time to preserve the patient's neurological conditions without the risk of complications, but it can also be counted on to provide a cure. However, radiosurgery as an excising device is more insidious than the microsurgical scalpel, since the narrow beam of radiation, directed to a limited target without opening the skull, is invisible. The expression coined by Lars Leksell regarded precisely the innovation he himself conceived in the 'closed skull operation', with reference to its use in cases of acoustic neurinoma as an alternative to traditional surgery. Hence, whatever technique or instruments are involved, it is always a question of interventional neuroradiology or minimally invasive neurosurgery.

    1991-01-01

    Pliny's historical outline of the development of medicine, in Natural History 29.1-27, is our primary source concerning the reception of scientific medicine at Rome during the later Republic and early Empire. Here, as elsewhere, Pliny handles Greek doctors and their medical practices with vehement disapproval. But this attitude, at first glance anti-Hellene, traditionalistic, and critical of his coevals, arises from more deeply rooted notions: a specific conception of nature which can be shown to be the basis of Pliny's critique of medicine and his own times. Reconstruction of this "Plinean" conception reveals a view of nature marked by Stoic terminology and categories, though in fact derivate from various sources, idiosyncratic and characterized by a genuine love of and respect for nature and her creations. True comprehension of the lessons offered by nature, resulting in concrete mores of behaviour and moral categories, as opposed to theory and speculation, is the proper modus operandi for Pliny. And thus, with regard to the human process of self-discovery in the natural world, medicine plays a decisive role--for providential nature displays herself most clearly in the production of healing substances. Pliny notes among the proponents of scientific medicine, a general disregard for nature and her rules, while he finds just the opposite in traditional medicine. His own accomplishment resides not only in the safeguarding of numberless recipies from the world of folk medicine, but also in the facts that he under-pins these traditional methods of healing, and their basic principles, with a specific conception of nature, and that he marks out an exceptionally important place for traditional methods of healing in the canon of general knowledge.

  1. Gaseous Structures in Barred Galaxies: Effects of the Bar Strength

    2012-10-01

    Using hydrodynamic simulations, we investigate the physical properties of gaseous substructures in barred galaxies and their relationships with the bar strength. The gaseous medium is assumed to be isothermal and unmagnetized. The bar potential is modeled as a Ferrers prolate with index n. To explore situations with differing bar strength, we vary the bar mass f bar relative to the spheroidal component as well as its aspect ratio { R}. We derive expressions as functions of f bar and { R} for the bar strength Qb and the radius r(Qb ) where the maximum bar torque occurs. When applied to observations, these expressions suggest that bars in real galaxies are most likely to have f bar ~ 0.25-0.50 and n <~ 1. Dust lanes approximately follow one of the x 1-orbits and tend to be straighter under a stronger and more elongated bar, but are insensitive to the presence of self-gravity. A nuclear ring of a conventional x 2 type forms only when the bar is not so massive or elongated. The radius of an x 2-type ring is generally smaller than the inner Lindblad resonance, decreases systematically with increasing Qb , and is slightly larger when self-gravity is included. This is evidence that the ring position is not determined by the resonance, but instead by the amount of angular momentum loss at dust-lane shocks. Nuclear spirals exist only when the ring is of the x 2 type and is sufficiently large in size. Unlike the other features, nuclear spirals are transient in that they start out being tightly wound and weak, and then, due to the nonlinear effect, unwind and become stronger until they turn into shocks, with an unwinding rate that is higher for larger Qb . The mass inflow rate to the galaxy center is found to be less than 0.01 M ⊙ yr-1 for models with Qb <~ 0.2, while becoming larger than 0.1 M ⊙ yr-1 when Qb >~ 0.2 and self-gravity is included.

    Introducción: La cirugía de los trastornos del comportamiento (CTC) se está convirtiendo en un tratamiento más común desde el desarrollo de la neuromodulación. Métodos: Este artículo es una revisión no sistemática de la historia, indicaciones actuales, técnicas y blancos quirúrgicos de la CTC. Dividimos su historia en 3 eras: la primera comienza en los inicios de la psicocirugía y termina con el desarrollo de las tícnicas estereotácticas, cuando comienza la segunda era. Ésta se caracteriza por la realización de lesiones estereotácticas. Nos encontramos transitando la tercera era, que comienza cuando la estimulación cerebral profunda (ECP) comienza a ser usada en CTC. Resultados: A pesar de los errores graves cometidos en el pasado, hoy en día, la CTC está renaciendo. Los trastornos psiquiátricos que se más frecuentemente se tratan con cirugía son: depresión refractaria, trastorno obsesivo-compulsivo y síndrome de Tourette. Además, algunos pacientes con agresividad fueron tratados quirúrgicamente. Hay varios blancos estereotácticos descriptos para estos trastornos. La estimulación vagal puede ser usada también para depresión. Conclusión: Los resultados de la ECP en estos trastornos parecen alentadores. Sin embargo, se necesitan más estudios randomizados para establecer la efectividad de la CTC. Debe tenerse en cuenta que una apropiada selección de pacientes nos ayudará a realizar un procedimiento más seguro así como también a lograr mejores resultados quirúrgicos, conduciendo a la CTC a ser más aceptada por psiquiatras, pacientes y sus familias. Se necesita mayor investigación en varios temas como: fisiopatología de los trastornos del comportamiento, indicaciones de CTC y nuevos blancos quirúrgicos. PMID:25165612

El fracaso de las teorías de bifurcación para explicar la formación de estrellas dobles ha puesto en consideración los encuentros de estrellas en cúmulos para formar binarias. Existen muchas pruebas empíricas que pueden realizarse para verificar las creencias actuales. En esta revisión del tema se hace un breve resumen de la historia del problema y se analiza el conocimiento actual. Se proponen las investigaciones y programas que darían lugar a la comprobación de las predicciones que surgen de considerar que las binarias en cúmulos se forman por encuentros.

    Desde tiempos prehistoricos han sido coleccionadas piedras que caen dei cielo. Hasta hace poco eran la unica fuente para hacer estudios de laboratorio de la materia extragal, ktica, e incluso en nuestra era espacial, siguen siendo una valiosa fuente de investigacion de la temprana historia dei sistema solar. Se estima que como termine medio cada kilometro cuadrado de la superficie terrestre es golpeada cada millon de aiios por un meteorito con un pese superior a 500 gramos. La mayoria se pierden en los oceanos 0 caen en regiones con escasa poblacion. Como resultado, los museos en el munda reciben anualmente tan solo alrededor de 6 meteoritos cuya caida fuera atestiguada. Otros llegan por hallazgos casuales que en la mayoria de los casos son meteoritos que han cardo en tiempos prehistoricos.

    The type specimens of amphibians and reptiles of the Museo de Historia Natural Alfredo Dugès, at the University of Guanajuato (MADUG) were reviewed following Smith & Necker's (1943) summary. Owing to this collection's eventful history and its historical importance as the oldest herpetological collection in Mexico, a review of its conservation status was needed. After many years, the collection has received proper recognition at the University of Guanajuato with a portion of the herpetological types considered "Precious Assets" of the university. We found 34 type specimens pertaining to 18 taxa; six are additional specimens to those previously reported; six herpetological types are missing, including the body of the type of Adelophis copei. All specimens are in good to reasonable condition except for the type of Rhinocheilus antonii, which has dried out completely. All specimens are illustrated to show their condition.

    The year 2014 has marked the tercentenary from the death of Bernardino Ramazzini (1633-1714), universally credited as the founder of Occupational Health (5, 9, 10, 11). Indeed, the renowned physician died on November 5th 1714 in Padua, where he had been appointed as Professor of Practical Medicine at the local prestigious University from the year 1700. To commemorate this anniversary, the professors of Occupational Health of the University of Padua, the Italian Society of Occupational Health and Industrial Hygiene (Società Italiana di Medicina del Lavoro eIgiene Industriale, SIMLII), the International Commission on Occupational Health (ICOH) and the University of Padua organized a conference in the wonderful location of Palazzo Bo (Main Hall) under the patronage of the Padua Municipality, the Workers' Compensation Authority (INAIL), the Venetian Region and the Societas Internationalis Historiae Medicinae.[...].

  8. Markers for geodynamic stability of the Variscan basement: case study for the Montseny-Guilleries High (NE Iberia)

    The Montseny-Guilleries High is a Miocene horst composed of Variscan basement rocks, situated in the northeastern part of the Catalan Coastal Ranges (NE Iberia). The Montseny-Guilleries High has an asymmetric profile with an abrupt faulted scarp at the southeastern margin and a smooth surface dipping to the Northwest; here Paleocene sediments of the Ebro basin margin are to some extend in onlap. The stratigraphic arrangement of the Mesozoic units in the Catalan Coastal Ranges indicate that the Montseny-Guilleries area was a relief during the Mesozoic, remaining exposed probably from the Permian to the Cretaceous [Anadón et al., 1979; Gómez-Gras, 1993]. The high subsequently has been faulted due to a rifting phase that took place during the Miocene [Anadón et al., 1979]. The geodynamic history (burial-exhumation processes and denudation rate) of the Montseny-Guilleries High can be deciphered from cooling markers, such as for example apatite fission tracks [Juez-Larré & Andriessen, 2006]. However, the cooling history of an area depends on many factors (i.e. denudation rate, variations of the geothermal gradient) that complicate interpretations [Juez-Larré & Ter Voorde, 2009]. Another solution is to search for datable paleoweathering records in order to obtain benchmarks for ancient surfaces of continental exposure. This is the case for the Permian-Triassic paleosurface, at which an extensive albitization-hematisation alteration occurred at shallow depth [Thiry et al., 2009]. Several paleoalterations have been identified in the Montsent-Guilleries High [Gómez-Gras & Ferrer, 1999]. These alterations are coupled to the smooth surface or peneplain of the northwestern margin of the high and form a paleoprofile with less altered rocks on the lower parts of the relief and more altered rocks located at the higher parts of the relief (i.e. on the peneplain). From base to top, the profile starts with week albitization-hematisation of the facies developed mainly in the

In 1996 in my collection of papers entitled, ''Reflections on Experimental Science,'' I gave a straightforward account of the experimental method and the physics involved in the discovery as an introduction to the collection. In a 2002 paper written with Mary A. Meyer published in the journal ''Theoria et Historia Scientiarum'' I used the story of the discovery to outline my thoughts on the practice of experimental science. That 2002 paper was written primarily for young women and men who are beginning their lives in science and it was based on a lecture given at Los Alamos National Laboratory. Some of the historical material in this paper has appeared in those two earlier papers.

    Franciscan missionary Fray Bernardino de Sahagún arrived in New Spain (Mexico) in 1529 to proselytize Aztecs surviving the Conquest, begun by Hernán Cortés in 1519. About 1558 he commenced his huge opus "Historia general de las cosas de Nueva España" completed in Latin-Nahuatl manuscript in 1569. The best surviving version, the "Florentine Codex," 1579 in Spanish-Nahuatl, is the basis for the editions published since 1829. The first English translation was issued in 13 volumes between 1950 and 1982, and the first facsimile was published in 1979. Book 11, "Earthly things," is a comprehensive natural history of the Valley of Mexico based on pre-Cortésian Aztec knowledge. Sahagún's work, largely unknown among English-speaking biologists, is an untapped treasury of information about Aztecan natural history. It also establishes the Aztecs as the preeminent pioneering naturalists of North American, and Sahagún and his colleagues as their documentarians.

    Asbestos was used in making pottery in Eastern Finland from around 4000 B.C. In the ancient era and in the Middle Ages, magic properties were frequently attributed to this mineral. In the first century A.D., the Latin encyclopaedist Pliny the Elder reported in his Historia Naturalis that asbestos protects against all poisonings, particularly that of magicians. Moreover, asbestos was often found in places of worship, in Rome as well as in Athens and in Jerusalem. In the Middle Ages asbestos was identified with some animals, such as the salamander and certain white rodents. With such appearance, the mineral  had a huge success in Western as well as in Eastern literature and the fine arts. Marco Polo (1254-1324) in the Milione tried to deny that asbestos was a salamander. Despite its noxious effects, asbestos continues to be used in much of the world. In the 21st century it seems to be maintaining its quality as a magic stone.

    This paper is a reflection about the use of History of Science in the curriculum of formal education, through the discussion concerning cultural elements of several ethnic groups in Brazil, in actions related to astronomy education. The work was developed in the framework of an extension course and the analysis undertaken here refers to a meeting that discussed didactic sequences relating to that theme, based on the Brazilian law 11.645/2008, which states the obligation to present the subject "African-brazilian and indigenous History and Culture" in the official curriculum. The extension action was developed with teachers who teach Natural Sciences, in São Paulo state, discussing issues related to the use of History of Science and the relationship with cosmogonies from Iorubá and Tupi peoples, highlighting how they can enhance the work with Astronomy(ies) in the classroom. It was observed that the participants had not yet presented these themes in their classes and also did not participate in training courses that discussed these subjects.

  18. Ecological impacts of non-native species

    Non-native species are considered one of the greatest threats to freshwater biodiversity worldwide (Drake et al. 1989; Allen and Flecker 1993; Dudgeon et al. 2005). Some of the first hypotheses proposed to explain global patterns of amphibian declines included the effects of non-native species (Barinaga 1990; Blaustein and Wake 1990; Wake and Morowitz 1991). Evidence for the impact of non-native species on amphibians stems (1) from correlative research that relates the distribution or abundance of a species to that of a putative non-native species, and (2) from experimental tests of the effects of a non-native species on survival, growth, development or behaviour of a target species (Kats and Ferrer 2003). Over the past two decades, research on the effects of non-native species on amphibians has mostly focused on introduced aquatic predators, particularly fish. Recent research has shifted to more complex ecological relationships such as influences of sub-lethal stressors (e.g. contaminants) on the effects of non-native species (Linder et al. 2003; Sih et al. 2004), non-native species as vectors of disease (Daszak et al. 2004; Garner et al. 2006), hybridization between non-natives and native congeners (Riley et al. 2003; Storfer et al. 2004), and the alteration of food-webs by non-native species (Nystrom et al. 2001). Other research has examined the interaction of non-native species in terms of facilitation (i.e. one non-native enabling another to become established or spread) or the synergistic effects of multiple non-native species on native amphibians, the so-called invasional meltdown hypothesis (Simerloff and Von Holle 1999). Although there is evidence that some non-native species may interact (Ricciardi 2001), there has yet to be convincing evidence that such interactions have led to an accelerated increase in the number of non-native species and cumulative impacts are still uncertain (Simberloff 2006).

    The paper focuses on the structure of the obstetric market in a rural region of alpine South Tyrol (today: Italy) throughout the 1860s. Besides midwives and parturient women, also male obstetricians are traceable in the actual research area of the Tauferer Ahrntal. Among them was the general practitioner Dr. Franz von Ottenthal, whose medical records (Historiae Morborum, 1847-1899) are used to reconstruct the participation of physicians in the obstetric market. Special emphasis lies on the evaluation of the predominant hierarchies (midwives/surgeons/physicians) and the position of Franz von Ottenthal in this specialized medical sub-segment. Therefore, the quantitative extent of obstetric intervention as well as the qualitative dimension of treatments (medication, surgeries) is investigated. So far, the relevance of Ottenthals obstetric practice as to the gender ratio has been measured as rather high, considering that he generally treated more female than male patients. An attempt will be made to estimate the significance of the obstetric segment within his practice in order to find an explanatory approach for the higher female medical demand.

    The history of Roman pharmacology is ponctuated with ideological debates about relevance of this art. Thus, Hippocrates --a contemporary of Socrates who was teaching that "science of remedies and science of poisons are the same"--was given credit for favourable mood towards pharmaceuticals by Scribonius Largus on the basis of therapeutic complementarity. Among the Latin doctors of the late Roman Empire, Marcellus Empiricus and Caelius Aurelianus, Hippocrates appeared as an authority favourable towards medication, especially in a fictitious letter written by Marcellus to the Claudian emancipated slave Callistus. Likewise, popular philosophy has taken over the Socratic antinomy between remedia and uenena. Last but not least, Sextius Niger wrote a pharmacopoeia attested as an official source by Celsus and plentifully consulted by Pliny the Elder: the Naturalis historia allows to delimit Sextius' contribution to the recurring controversy about use of pharmaceuticals. In such a context, the antipharmaceutical argument entered by Asclepiades of Bithynia fulfils a provocative function, the historical impact of which needs to be assessed according to the present-day speculation about "useful, useless or dangerous medicines".

Esta galaxia, un miembro del Cúmulo de Fornax que no ha sido estudiado previamente, muestra una morfología muy particular: una distribución estelar subyacente de bajo brillo superficial (LSB) con varias manchas brillantes dispuestas en una estructura anular deformada. Por sus colores muy azules se infiere que estas son zonas de formación estelar reciente. Al norte del cuerpo principal de la galaxia, y conectado con éste mediante filamentos LSB, hay un objeto de isofotas aproximadamente circulares. Este objeto tiene en sí mismo algunas zonas brillantes, pero su población estelar subyacente es significativamente más azul que la del cuerpo principal de la galaxia. Esto indica que ambos objetos han tenido distintas historias evolutivas. Estructuralmente, el objeto del norte es muy similar a algunas de las galaxias elípticas enanas más débiles que pueblan el Cúmulo de Fornax. Se discute la posible relación entre este objeto y la galaxia en si.

    albitization. Biotites are not or weakly chloritized. However, these "unaltered" (or primary) granites are strongly weathered into granite boulders embedded in grus by the present-day climatic conditions. The maturest paleoprofiles occur at the northern part of the Catalan Coastal Ranges (i.e. the Montseny-Guilleries High) where the Variscan basement remained exposed during Triassic times. Towards the South the profiles progressively disappear and Triassic sediments acquire their maximum thickness here. The alteration profiles are related with the Permo-Triassic paleosurface still outcroping on wide areas [Gómez-Gras and Ferrer, 1999]. They are partially covered by Triassic fluvial sandstones (Buntsandstein facies) in the South [Gómez-Gras, 1993] and by Palaeocene alluvial conglomerates in the West [Anadón et al., 1979]. The Triassic paleosurface shows a remarkable stability successively outcropping during Mesozoic and Tertiary times, the pre-Tertiary exhumation and even the present day weathering affected very little these albitized profiles. The hardness and thus preservation of the Triassic paleosurface is mainly related to the albitization. The albitized granites are entirely lacking anorthitic plagioclase, which is much more sensitive to chemo-mechanical weathering. Development of albite and additional chloritization of the primary biotite crystals render the rocks much more resistant to weathering and erosion. This stability is particularly well expressed in case of the Montseny-Guilleries High, which is limited by a high fault scarp at the south-eastern margin. The albitized top of the scarp shows remarkably hard fresh rocks, whereas the base of the scarp (formed of primary, non-albitized facies) is deeply weathered into gruss. This is causing much smother landscape reliefs in the valleys and thalwegs. Since a long time the remarkable persistence of the Triassic paleosurface expressed in the Paleozoic massifs has been highlighted by geomorphologists. Only recently we

    Resumen El objetivo de este estudio fue desarrollar fotonovelas, un tipo de novela gráfica popular en la población latina, para crear conciencia y educar sobre los trastornos de la conducta alimentaria (TCA). Cuatro caricaturas ilustradas y guiones adaptados para adultos y adolescentes de ambos sexos fueron presentados en discusiones focales y en una entrevista de profundidad. Diecisiete latinos adultos (14 mujeres; 3 hombres) y 10 adolescentes (9 féminas; 1 varón) participaron en el estudio. Los participantes encontraron las fotonovelas interesantes y que captaban más la atención que los folletos tradicionales. El uso del espanglish y la clarificación de las diferencias entre los TCA fueron sugeridos por las adolescentes femeninas. Los adultos varones sugirieron cambiar el título, que se enfocara en las consecuencias en la salud de los TCA para que llame la atención en los hombres a leer la historia.

  6. John Flamsteed and the turn of the screw: mechanical uncertainty, the skilful astronomer and the burden of seeing correctly at the Royal Observatory, Greenwich.

    PubMed

    Spiegel, Richard J

    2015-03-01

    Centring on John Flamsteed (1646-1719), the first Astronomer Royal, this paper investigates the ways in which astronomers of the late seventeenth century worked to build and maintain their reputations by demonstrating, for their peers and for posterity, their proficiency in managing visual technologies. By looking at his correspondence and by offering a graphic and textual analysis of the preface to his posthumous Historia Coelestis Britannica (1725), I argue that Flamsteed based the legitimacy of his life's work on his capacity to serve as a skilful astronomer who could coordinate the production and proper use of astronomical sighting instruments. Technological advances in astrometry were, for Flamsteed, a necessary but not a sufficient condition for the advancement of astronomy. Technological resources needed to be used by the right person. The work of the skilful astronomer was a necessary precondition for the mobilization and proper management of astronomical technologies. Flamsteed's understanding of the astronomer as a skilled actor importantly shifted the emphasis in precision astronomical work away from the individual observer's ability to see well and toward the astronomer's ability to ensure that instruments guaranteed accurate vision.

    Se examinó la prevalencia de experiencias atípicas psicóticas y cuasi-psicóticas y se identificaron factores asociados a éstas en 162 jóvenes puertorriqueños/as entre 13 y 17.5 años. Se evaluó la sintomatología depresiva, la ideación suicida, así como la presencia o historia de experiencias atípicas, eventos traumáticos y maltrato o abuso. Las experiencias atípicas estuvieron asociadas (p<.05) a ser fémina, a tener enfermedades físicas, a experimentar eventos traumáticos, a haber recibido tratamiento para la depresión, y a una sintomatología depresiva e ideación suicida elevada. Los eventos traumáticos, el tratamiento farmacológico para la depresión y la severidad de la ideación suicida fueron predictores significativos del número de experiencias reportadas. Los resultados confirman que la mayoría de las experiencias no son psicóticas. Se discuten las implicaciones para la evaluación y el tratamiento de jóvenes deprimidos/as.

    Este artículo documenta una respuesta agregada negativa del logro educativo superior (más de 12 años de escolaridad) en México a la recesión de 1982–83 y el estancamiento que le siguió. La respuesta no fue homogénea entre géneros, regiones y entornos familiares. Los hombres experimentaron una caída en el logro mientras que las mujeres experimentaron un crecimiento más lento. En promedio, los estados con un mayor logro antes del choque experimentaron mayores caídas. La respuesta entre distintos entornos familiares no presenta un patrón claro. Sin embargo, el efecto negativo en el logro se observa incluso entre hermanos. La evidencia sugiere una historia por el lado de la demanda: la caída en el ingreso de los hogares parece ser el determinante de la caída/desaceleración del logro educativo superior. La conclusión es que la recesión y la falta de crecimiento que le siguió tuvieron un efecto negativo importante y duradero en la formación de capacidades en México. PMID:25328251

    Las picaduras por himenópteros son frecuentes en la infancia. La mayoría producen reacciones locales, consecuencia de un mecanismo inflamatorio, no alérgico, no tienen progresión y se resuelven con simples medidas terapéuticas. Las reacciones más extensas, generalmente, están asociadas a mecanismos alérgicos, mediados por inmunoglobulina E. Su máxima expresión, la anafilaxia, presenta síntomas cutáneos, respiratorios, cardiovasculares, digestivos y/o neurológicos, con riesgo de muerte. La prevalencia de anafilaxia en pacientes con mastocitosis sistémica es más alta. La familia Hymenoptera, que incluye hormigas coloradas, abejas y avispas, es la causante de las picaduras de mayor riesgo, potencialmente fatales. Los pilares del diagnóstico son la historia clínica, la identificación del insecto, y las pruebas diagnósticas cutáneas y/o in vitro interpretadas por el especialista en Alergia e Inmunología. La inmunoterapia con veneno es el tratamiento de elección para prevenir reacciones anafilácticas por picaduras de himenópteros.

    The presence of ancient Maya shrines in caves serves as unequivocal evidence for the ritual appropriation of these subterranean spaces and their significance with respect to Maya religious practice. Detailed study of the miniature masonry temples and altar features in the caves of Quintana Roo, Mexico reveals a strong stylistic and likely functional correspondence between these structures and their terrestrial counterparts at Postclassic sites. The Proyecto Arquitectura Subterranea de Quintana Roo (coordinated by the Center of Interdisciplinary Science for Art, Architecture, and Archaeology, or CISA3, at the University of California, San Diego and in collaboration with the Instituto Nacional de Antropologia e Historia in Mexico) is conducting a survey and program of digital documentation of both the pristine and impacted cave shrines of the region. Once an area is developed and populated, and access is opened to caves containing ancient architectural features, they are soon vandalized - often resulting in the complete obliteration of these rare miniature buildings and their diagnostic architectural elements. This emergent situation necessitates the use of rapid reality-capture tools; however, the physical challenges of working in caves requires researchers of adapt increasingly common architectural documentation methodologies to more adverse field conditions.

    Janick, Jules; Paris, Harry S.; Parrish, David C.

    2007-01-01

    Background A critical analysis was made of cucurbit descriptions in Dioscorides' De Materia Medica, Columella's De Re Rustica and Pliny's Historia Naturalis, works on medicine, agriculture and natural science of the 1st century ce, as well as the Mishna and Tosefta, compilations of rabbinic law derived from the same time period together with cucurbit images dating from antiquity including paintings, mosaics and sculpture. The goal was to identify taxonomically the Mediterranean cucurbits at the time of the Roman Empire. Findings By ancient times, long-fruited forms of Cucumis melo (melon) and Lagenaria siceraria (bottle gourd) were selected, cultivated and used as vegetables around the Mediterranean and, in addition, bottle-shaped fruits of L. siceraria were employed as vessels. Citrullus lanatus (watermelons) and round-fruited forms of Cucumis melo (melons) were also consumed, but less commonly. A number of cucurbit species, including Bryonia alba, B. dioica, Citrullus colocynthis and Ecballium elaterium, were employed for medicinal purposes. No unequivocal evidence was found to suggest the presence of Cucumis sativus (cucumber) in the Mediterranean area during this era. The cucumis of Columella and Pliny was not cucumber, as commonly translated, but Cucumis melo subsp. melo Flexuosus Group (snake melon or vegetable melon). PMID:17932073

  15. What was historical about natural history? Contingency and explanation in the science of living things.

    PubMed

    Harrison, Peter

    2016-08-01

    There is a long-standing distinction in Western thought between scientific and historical modes of explanation. According to Aristotle's influential account of scientific knowledge there cannot be an explanatory science of what is contingent and accidental, such things being the purview of a descriptive history. This distinction between scientia and historia continued to inform assumptions about scientific explanation into the nineteenth century and is particularly significant when considering the emergence of biology and its displacement of the more traditional discipline of natural history. One of the consequences of this nineteenth-century transition was that while modern evolutionary theory retained significant, if often implicit, historical components, these were often overlooked as evolutionary biology sought to accommodate itself to a model of scientific explanation that involved appeals to laws of nature. These scientific aspirations of evolutionary biology sometimes sit uncomfortably with its historical dimension. This tension lies beneath recent philosophical critiques of evolutionary theory and its modes of explanation. Such critiques, however, overlook the fact that there are legitimate modes of historical explanation that do not require recourse to laws of nature. But responding to these criticisms calls for a more explicit recognition of the affinities between evolutionary biology and history. Crown Copyright © 2015. Published by Elsevier Ltd.

    La historia de la migración México-Estados Unidos se caracteriza por una serie de periodos durante los cuales los patrones migratorios se transforman y evolucionan como respuesta a los cambios en la política migratoria de Estados Unidos. En la década de 1990 se dio uno de estos cambios, lo que provocó el paso de la ‘era de la contradicción’ a la ‘era de la marginalización’. Actualmente, un gran número de migrantes indocumentados permanecen al margen de la ley, precisamente en un periodo en el que las penas se han incrementado y la persecución ha alcanzado niveles récord. De manera cada vez más notoria, los migrantes indocumentados, por la represión interna y fronteriza, quedan obligados a romper los lazos que los vinculaban con sus lugares de destino, pero al mismo tiempo se sienten cada vez más extraños en una tierra donde la aplicación de políticas antiinmigrantes es cosa de todos los días, lo que los sitúa en una posición de marginalización y gran vulnerabilidad.

  19. An interior penalty stabilised incompressible discontinuous Galerkin-Fourier solver for implicit large eddy simulations

    Ferrer, Esteban

    2017-11-01

    We present an implicit Large Eddy Simulation (iLES) h / p high order (≥2) unstructured Discontinuous Galerkin-Fourier solver with sliding meshes. The solver extends the laminar version of Ferrer and Willden, 2012 [34], to enable the simulation of turbulent flows at moderately high Reynolds numbers in the incompressible regime. This solver allows accurate flow solutions of the laminar and turbulent 3D incompressible Navier-Stokes equations on moving and static regions coupled through a high order sliding interface. The spatial discretisation is provided by the Symmetric Interior Penalty Discontinuous Galerkin (IP-DG) method in the x-y plane coupled with a purely spectral method that uses Fourier series and allows efficient computation of spanwise periodic three-dimensional flows. Since high order methods (e.g. discontinuous Galerkin and Fourier) are unable to provide enough numerical dissipation to enable under-resolved high Reynolds computations (i.e. as necessary in the iLES approach), we adapt the laminar version of the solver to increase (controllably) the dissipation and enhance the stability in under-resolved simulations. The novel stabilisation relies on increasing the penalty parameter included in the DG interior penalty (IP) formulation. The latter penalty term is included when discretising the linear viscous terms in the incompressible Navier-Stokes equations. These viscous penalty fluxes substitute the stabilising effect of non-linear fluxes, which has been the main trend in implicit LES discontinuous Galerkin approaches. The IP-DG penalty term provides energy dissipation, which is controlled by the numerical jumps at element interfaces (e.g. large in under-resolved regions) such as to stabilise under-resolved high Reynolds number flows. This dissipative term has minimal impact in well resolved regions and its implicit treatment does not restrict the use of large time steps, thus providing an efficient stabilization mechanism for iLES.

    The life and work of Santiago Ramon y Cajal has been portrayed in scientific papers, biographical and autobiographical works, comics, films, television series or documentaries that have attempted to reflect upon his life or his contributions to science and to bring him closer to the general public. To analyse the different ways Santiago Ramon y Cajal has been represented in literature, cinema and television, and to become more closely acquainted with this scientist through his fictional writings. A number of biographical works have been written about Santiago Ramon y Cajal, including scientific papers, comics, books for children and youngsters, as well as the autobiographical writings, essays and even science fiction stories, which provide a good introduction to the life of the scientist and his work. His life has also been adapted to film (Leap to fame) or television (Ramon y Cajal, historia de una voluntad; The butterflies of the soul), which have, with varying degrees of success and accuracy, made him better known to the general population. The numerous biographical writings, historical notes, articles, the scientific work itself, the essays and fictional works by Cajal, as well as the portrayals of the Spanish Nobel Prize winner produced for films and television, can be used to obtain some interesting insights into the scientist, teacher, science populariser, humanist physician and, in short, the man who made such important contributions to neuroscience.

    The objective of the present work is to examine images of the brain dissection by Flemish-born anatomist Andreas Vesalius (1514-1564) as originally represented in the Fabrica (1543), and later copied without Vesalius' permission by Spanish anatomist Juan Valverde de Hamusco (c1525-c1587) in Historia de la composicion del cuerpo humano (1556). Illustrations of the brain dissection in the Fabrica were obtained in digital form, resized, and arranged in a comparable montage to that presented by Valverde. Computer manipulations were used to assess image correspondence. The Valverde illustrations are approximately half the size and are mirror images of those in the Fabrica, but otherwise show the same dissection stages, and identical transverse brain levels and structures. The Valverde illustrations lack shadowing and show minor variations in perspective and fine details (e.g., branching pattern of the middle meningeal artery) from those in the Fabrica. Craftsmen under the direction of Valverde copied the woodcut prints in the Fabrica in close but approximate form by freehand engraving onto copper plates. Differences in the sizes of the images, and in perspective and fine detail, preclude direct tracing of images as the means of copying. Because engravings are in effect "flipped over" to make further prints, subsequent prints made from Valverde's copperplate engravings are mirror images of the prints in Vesalius' Fabrica.

    2018-01-01

    Abstract Modern biology builds upon the historic exploration of the natural world. Recognizing the origin of a species’ name is one path to honor the historic exploration and description of the natural world and the indigenous peoples that lived closely with organisms prior to their description. While digitization of historic papers catalogued in databases such as the Biodiversity Heritage Library (BHL) allows for searching of the first use and origin of names, the rapid pace of taxonomic publishing can occlude a thorough search for etymologies. The etymological origin of the genus name Ameiva is one such case; while unattributed in multiple recent works, it is of Tupí language origin. The first description was in the Historiae Rerum Naturalium Brasiliae by George Marcgrave (1648). Ameiva was the name used by Marcgrave’s Amerindian hosts in 17th century Dutch Brazil, where local people spoke the now extinct language Tupí. The Tupí origin was not lost, however, until as recently as the 2000s. Herein, the pre- and post-Linnaean use of the name Ameiva is traced and when the name is attributed to the Tupí language and to Marcgrave through time it is noted. The opportunity to discover and/or recover etymological origins, especially names from extinct and indigenous languages, provides insight into the early Western sciences. Careful study of etymology by naturalists is consistent with the idea that science is an evolving process with many predecessors to appreciate. PMID:29674919

  5. Examples and experience: on the uncertainty of medicine.

    PubMed

    Pender, Stephen

    2006-03-01

    After a brief account of the uncertainty of medicine in early modern thought, this paper focuses on two supple, sophisticated accounts of medicine by 'non-medical' writers--Michel de Montaigne's views of medical theory and medical practice and Francis Bacon's proposals for renovating both--in which the claims of individual sufferers are set against the normativity of medicine as a whole. From around 1500 to around 1680, in the common ensemble of both learned and popular invective, medicine was disparaged as poor philosophy and worse practice, even as the 'lowest of professions'. In remarkably broad, elegant interventions, Montaigne argues that medicine is based on 'examples and experience' (and 'so is my opinion', he adds), impugning its universalizing claims with the tractable experience of his own embodiment, with his own historia and consilium, while Francis Bacon enlists dietetics, Hippocratic case-taking and medical history in his broad programme for the reform of medicine. He more or less accepts Montaigne's argument for particularity in medical theory and practice, but presses the particular into service in his reformist programme. Like many sixteenth- and early seventeenth-century scholars and physicians frustrated with Galenic methods and models, both turn to Hippocratic practice and to hygiene and dietetics as salves for an ailing discipline. Finally, I argue that both writers enquire into viable means for inflecting learned medicine with particular experience, and both settle on rhetorical tools - analogy and exemplarity - as the means by which universalized medical models might be particularized or reformed.

    The year 2004 signals the 400th anniversary of the birth of count Mauricio of Nassau, an important character in the history of Brazil. The present text is related to the period of Dutch domination in Pernambuco. The article attempts to rescue the beginnings of Astronomy study in the South hemisphere. Therefore, we idealized a dramatization of a fictitious interview with German astronomer Georg Marcgrave, who was the constructor of the first astronomical observatory in this hemisphere and the author of the first systematic astronomical observations using telescopes in this side of the world. Our "conversation" with Marcgrave is idealized in the old Recife scenario, a place where he lived in Mauricio of Nassau's period and gathers some fellow teachers who love the teaching of Astronomy. The story, this way, is reported in a possibly light and funny atmosphere. Nevertheless, the conceptual and historical framework presented is based on reliable bibliographical sources pointed out at the end of the text. The sources range from the original book of that scientist, in which a solar eclipse is reported, passing through some other classical texts, such as that of Professor Juliano Moreira, up to more recent sources such as the very influential work of professor John North. Other influential texts about the Dutch period in Brazil, such as the classical works of Charles Boxer, Bouman and Boogaart, among others, are also used in the construction of this pedagogical dramatization, which involves an interesting chapter of the history of Astronomy.

    La estrella simbiótica KX TrA = He2-177 fue observada espectroscópicamente con el telescopio de 2.15 m del CASLEO entre los años 1990 y 1996, utilizándose resoluciones intermedia y alta. El rango espectral estudiado se extiende desde 4400 Åa 7200 Å. La historia fotométrica de KX TrA presenta explosiones del mismo tipo que las mostradas por la nova lenta RR Tel y su espectro de alta excitación, muy rico en líneas de emisión, es también similar al de RR Tel. Por lo tanto, es importante analizar la evolución espectral de KX TrA en el tiempo, prestando especial atención a los posibles cambios en los niveles de excitación. Las emisiones presentes corresponden a transiciones permitidas y prohibidas con un amplio rango de ionización, incluyéndose las anchas e intensas líneas originadas por scattering Raman de O VI en λλ 6825 y 7082 Å. En el período cubierto por nuestras observaciones se estudia la variación de la intensidad relativa de las emisiones, el comportamiento de las velocidades radiales y los cambios de perfiles de las líneas, especialmente en Hα y Hβ. El contínuo de la región roja observada indica un tipo espectral no más tardío que M3 para la componente gigante fría del sistema.

RESULTADOS: se estudiaron a 1743 pacientes, de ellos 199 recibieron visita domiciliaria; la edad media de quien recibe visita es de 81,99 años; estos presentan mayor número de patologías de media 3,76; habitan en domicilio particular, si bien en conjunto presentan más institucionalización que los controles; el 50% no tiene identificado el Cuidador Principal; es mayor el número de visitas de las enfermeras a los pacientes que viven en residencias (p < 0,001). El 50% de casos no tiene plan de cuidados, con relación significativa (p < 0,001). No existen diferencias significativas en tiempo de vida entre los casos y los controles. CONCLUSIÓN: la visita domiciliaria del profesional en enfermería no repercute en la morbimortalidad; visita a los pacientes cuando ya ha aparecido el problema de salud, no hay datos de prevención.

    To determine whether the introduction of computer-aided prescribing helped reduce the administrative burden at primary care centers. Descriptive, cross-sectional design. Torreblanca Health Center in the province of Seville, southern Spain. From 29 October 2003 to the present a pilot project involving nine pharmacies in the basic health zone served by this health center has been running to evaluate computer-aided prescribing (the Receta XXI project) with real patients. All patients on the center's list of patients who came to the center for an administrative consultation to renew prescriptions for medications or supplies for long-term treatment. Total number of administrative visits per patient for patients who came to the center to renew prescriptions for long-term treatment, as recorded by the Diraya system (Historia Clinica Digital del Ciudadano, or Citizen's Digital Medical Record) during the period from February to July 2004. Total number of the same type of administrative visits recorded by the previous system (TASS) during the period from February to July 2003. The mean number of administrative visits per month during the period from February to July 2003 was 160, compared to a mean number of 64 visits during the period from February to July 2004. The reduction in the number of visits for prescription renewal was 60%. Introducing a system for computer-aided prescribing significantly reduced the number of administrative visits for prescription renewal for long-term treatment. This could help reduce the administrative burden considerably in primary care if the system were used in all centers.

  13. The debt of John Ray and Martin Lister to Guillaume Rondelet of Montpellier

    The fame of its medical university and its reputation for field botany attracted visitors from all over Europe to seventeenth-century Montpellier. It was there that Martin Lister first made the acquaintance of John Ray in 1665. Twenty years later, in London, they cooperated in the production of the ambitious and lavishly illustrated Historia Piscium based on the notes of the late Francis Willughby. Ray, Lister and others contributed additional material. In their own work on fishes, cetaceans and shellfish Ray and Lister were considerably indebted to the Libri de piscibus marinis of an earlier Montpellier professor, Guillaume Rondelet, whose Aristotelian/Galenic approach to the study of medicine and living things was distinguished by a quite exceptional level of knowledge about aquatic species, based on a secure grasp of the classical and contemporary literature, but above all on his own observations in rivers, lakes, lagoons and the open sea, and his domestication (and dissection) of marine species in ponds and aquaria at his country house. Rondelet's book proved useful to Ray and to Lister as a work of reference, as a stimulus for reflection on biological problems, as an aid to nomenclature, as a source of precise descriptions of species, in both words and pictures, as a model to be improved upon in taxonomy, as a warning against reliance on hearsay, and as a valuable account of observations and experiments. Ray used it in much the same way as he used the work of those sixteenth-century botanists who met with his approval. Several of these had been Rondelet's pupils.

    A large number of duplication monstrosities have been observed in cattle, sheep, pigs, horses, goats, cats and dogs, ever since the publication of the famous woodcut of a swine double monster by J. S. Brant in Basel in 1496, better known as the "wunderbare Sau von Landser im Elsass". Albrecht Dürer also made a woodcut of this double monster in front of the village Landser in 1496. A picture of a deer double monster was published in 1603 by Heinrich Ulrich in Germany. In the monograph De monstrorum causis, natura et differentiis ..., published by the Italian Fortunius Licetus in 1616 pictures of double monsters being half man half dog are found. These fantasy figures have been popular for a long time and were supposed to be really in existence. Apart from these fantasy figures many pictures are known from real veterinary double monsters. U. Aldrovandus described in 1642 in his Monstrorum historia, besides many fantasy figures, also real human and veterinary double monsters and he gave also good pictures of them. In the 19th century examples of veterinary duplication monstrosities were published by I. Geoffroy Saint-Hilaire (1832-37), E. F. Gurlt (1832), W. Vrolik (1840) and C. Taruffi (1881); they proposed also concepts concerning the etiology. In the second volume of his famous handbook of teratology (1907), E. Schwalbe described many veterinary double monsters and discussed the theories of the genesis of congenital malformations. Various theories concerning the genesis of double monsters have been given since Aristotle (384-322 B.C.). ...

    When J.E. Gilibert was nominated to head the Chair of Natural History in Vilnius, his task was to introduce education with European standards. He was aware of the potential of his students and the level of their secondary school education. At that time (1781), no textbooks were available in Poland presenting knowledge of botany; the first was written in 1785. Teachers were using assorted, sometimes hardly practical materials, such as excerpts from Roman authors. Gilibert was familiar with this situation from his experience in Grodno, where he had taught for 6 years. At best, learners, i.e. prospective students, were using guidebooks for farmers by Ch. Kluk. This state of affairs was essentially in accordance with original plans of the National Educational Committee, which intended a very practical course of Natural History. The Chair in Vilnius was founded to implement university level education; and Gilibert dedicated a lot of time to didactic recommendations which would help students to develop the competence of botanists capable of studying European literature and communicating with international scientists. This presentation focuses on two important documents. The first one, Prospectus praelectionum cursus Historiae Naturalis. Ad usum Alumnorum Alma uniwersitatis Vilnensis, containing the curriculum of Natural History in Vilnius, will be analyzed from the point of view of its philosophical, epistemic and practical significance. The other one, Exercitium botanicum in schola principe universitatis Vilnensis habendum die mensie Julii anno 1782 seu enumaratio metodica plantarum, will be of interest from the point of view of various methodical comments regarding other works by Gilibert.

    The fourth volume of GERBERTVS contains the acts of the symposia held in Rome, at the Odeion hall of Lettere faculty in Sapienza University on December 7, 2012 Gerbert Homo Novus and on March 13, 2013 on the pre and post humanistic figures. Laura C. Paladino presents the didactical activity of Gerbert as from Richer of Reims who completed his Historia Francorum in 998, before the election of Gerbert to the pontifical soil. Among these activities there is the teaching of astronomy and mathematics and the abacus, to which a special article of Jorge Nuno Silva is dedicated. The abacus increased dramatically the rapidity of the computations and some algoritms thaught by Gerbert and reported by his former student Bernelinus is very reliably invented by Gerbert himself, as Silva demostrates in his paper. Giancarlo Pani presents the relation between Galileo and Kepler, at the end of the humanistic period, showing interesting insights on the rather asymmetrical exchange of information between the two greater astronomer of 1600. Veronica Regoli presents the Cosmos of Dante, the ideal structure of the Divine Comedy. Patrick Demouy presents the new biography of Flavio G. Nuvolone where the great novelty is the noble origin of Gerbert from Carlat family, but before the marriage of his (presumed) father. His birth is shifted back to 938 with technical demostrations. Paolo Zanna compares the magisterium of Gerbert-Sylvester II and that one of John Paul II and pope Francesco. Finally C. Sigismondi presents the work and the activities of Pawel Max Maksym (1983-2013) who founded the Observatory &"Pope Sylvester II" in the town of Bukowiec, near Lodz, Poland.

    New paleovegetation and paleoclimatic reconstructions from the Sierra Madre Occidental (SMO) in northwestern Mexico are presented. This work involves climate and biome reconstruction using Plant Functional Types (PFT) assigned to pollen taxa. We used fossil pollen data from four Holocene peat bogs located at different altitudes (1500-2000 m) at the border region of Sonora and Chihuahua at around 28° N latitude (Ortega-Rosas, C.I. 2003. Palinología de la Ciénega de Camilo: datos para la historia de la vegetación y el clima del Holoceno medio y superior en el NW de la Sierra Madre Occidental, Sonora, Mexico.

Holocene altitudinal shifts in vegetation belts and environmental changes in the Sierra Madre Occidental, Northwestern Mexico. Submitted for publication of Palaeobotany and Palynology). The closest modern pollen data come from pollen analysis across an altitudinal transect from the Sonoran Desert towards the highlands of the temperate SMO at the same latitude (Ortega-Rosas, C.I. 2003. Palinología de la Ciénega de Camilo: datos para la historia de la vegetación y el clima del Holoceno medio y superior en el NW de la Sierra Madre Occidental, Sonora, Mexico.

    Introducción: los meningiomas del foramen óptico producen un rápido deterioro de la función visual aún cuando su tamaño es pequeño, por eso su diagnóstico y manejo difiere del resto de los meningiomas clinoideos. El propósito de este estudio es presentar la técnica y los resultados de nuestro manejo quirúrgico de meningiomas foraminales (MF). Pacientes y Métodos: se llevó a cabo una revisión de las historias clínicas de 47 pacientes con meningiomas primarios intraorbitarios. Se realizaron 52 cirugías en los pacientes con MF. Se empleó una craneotomía fronto-orbitaria, seguida de una descompresión extradural del canal óptico, resección del componente intraorbitario y exploración intradural del nervio óptico. Resultados: de los 12 pacientes con MF que presentaban la visión conservada, la agudeza visual fue preservada en 7 casos, mejoró en 2, y empeoró en 3. En 18 pacientes, el principal síntoma fue exoftalmos y en 35 pacientes ceguera unilateral. Ocurrieron 6 recurrencias, 2 a 10 años después de la resección quirúrgica. Cinco de ellos fueron reoperados. Se indicó radioterapia después de la recurrencia en 3 pacientes. Conclusión: el manejo de los MF continúa siendo controvertido y frecuentemente se propone un tratamiento conservador. Basados en nuestros hallazgos de frecuente extensión intracraneal, proponemos realizar una resección total o subtotal del tumor, preservando el nervio óptico en pacientes con visión prequirúrgica conservada.

    The Internet is a powerful tool with which to expand audience access, bringing students, teachers and the public to places and resources they might not otherwise visit or make use of. We will present Traditions of the Sun, an experiential Web site that invites exploration of the world's ancient observatories with special emphasis on Chaco Culture National Historic Park in the Four Corners region of the US and several sites in the Yucatan Peninsula in Mexico. Traditions of the Sun includes resources in English and Spanish along with a unique trilingual on-line book, "Traditions of the Sun, A Photographic Journal," containing explanatory text in Yucatec Maya as well. Traditions of the Sun offers rich opportunities for virtual visits to ancient sites used for solar observing while learning about current NASA research on the Sun and indigenous solar practices within a larger historical and cultural context. The site contains hundreds of photographs, historic images and rich multimedia to help tell the story of the Sun-Earth Connection. Visitors to the site can zoom in on the great Mayan cities of Chichen Itza, Uxmal, Dzibilchaltun, and Mayapan to learn about Mayan astronomy, history, culture, and science. They can also visit Chaco Canyon to watch sunrise over Pueblo Bonito on the summer solstice, take a virtual reality tour of the great kiva at Casa Rinconada or see panoramic vistas from Fajada Butte, an area which, for preservation purposes, is restricted to the public. Traditions of the Sun provides one model of how exploration and discovery can come to life for both formal and informal audiences via the Internet. Traditions of the Sun is a collaborative project between NASA's Sun-Earth Connection Education Forum, the National Park Service, Instituto National de Antropologia e Historia, Universidad Nacional Autonoma de Mexico, and Ideum.

  3. Investigating the potential of floating mires as record of palaeoenvironmental changes

    2012-04-01

    Peat-forming floating mires could provide an exceptional resource for palaeoenvironmental and environmental monitoring studies, as much of their own history, as well as the history of their surrounds, is recorded in their peat deposits. In his Naturalis historia (AD 77-79), Pliny the Elder described floating islands on Lake Vadimonis (now Posta Fibreno Lake, Italy). Actually, a small floating island (ca. 35 m of diameter and 3 m of submerged thickness) still occurs on this calcareous lake fed by karstic springs at the base of the Apennine Mountains. Here the southernmost Italian populations of Sphagnum palustre occur on the small surface of this floating mire known as "La Rota", i.e., a cup-formed core of Sphagnum peat and rhizomes of Helophytes, erratically floating on the water-body of a submerged doline, annexed to the easternmost edge of the lake, characterised by the extension of a large reed bed. Geological evidence point out the existence in the area of a large lacustrine basin since Late Pleistocene. The progressive filling of the lake caused by changing in climatic conditions and neotectonic events, brought about the formation of peat deposits in the area, following different depositional cycles in a swampy environment. Then, a round-shaped portion of fen, originated around lake margins in waterlogged areas, was somehow isolated from the bank and started to float. Coupling data about concentrations and fluxes of several major and trace elements of different origin (i.e., dust particles, volcanic emissions, cosmogenic dusts and marine aerosols), with climate records (plant micro- and macrofossils, pollens, isotopic ratios), biomolecular records (e.g., lipids), detailed age-depth modelling (i.e., 210Pb, 137Cs, 14C), and humification indexes, the present work is hoped to identify and better understand the reliability of this particular "archive", and thus possible relationships between biogeochemical processes occurring in this floating bog and environmental

  4. Early Silurian Foraminifera from Gondwana - an early origin of the multichambered globothalamids?

    2017-04-01

    Early Silurian foraminifera until now have been regarded to consist of simple single-chambered monothalamids and two-chambered tubothalamids with an agglutinated wall. Although pseudo-multichambered agglutinated foraminifera first appeared in the mid-Ordovician (Kaminski et al. 2009), the origin of true multichambered forms was not believed to have taken place until the early or middle Devonian at the earliest (Holcová, 2002). New discoveries from the Lower Silurian Qusaiba Shale Member in Saudi Arabia point to an earlier origin of the multichambered globothalamid Foraminifera than the currently accepted estimate of 350 Ma (Pawlowski et al. 2003). The agglutinated foraminiferal genera Ammobaculites and Sculptobaculites have been recovered from dark graptolite-bearing claystones of Telychian age, from the transitional facies between the Qusaiba and Sharawa Members of the Qasim Formation at the type locality near Qusaiba town, Saudi Arabia. The multichambered lituolids occur as rare components in a foraminiferal assemblage consisting mostly of monothalamids. This new finding revises our understanding of the early evolution of the multichambered globothalamid foraminifera. The fossil record now shows that the globothalamids were already present in Gondwana by 435 m.y. Holcová, K. 2002.

    Objetivo: analizar la geografía del estado nutricional en España y su evolución entre mediados del siglo xixy comienzos del siglo xx, etapa previa a la transición nutricional con alta prevalencia de malnutrición.Métodos: se utilizan datos antropométricos agregados (promedios provinciales de estatura) del reclutamiento militar en 1858 y 1913, así como promedios provinciales de estatura y peso procedentes de una revisión realizada entre 119.571 soldados en 1903-1906. Con estos datos se elaboran cartografía y estadísticos descriptivos.Resultados: los parámetros antropométricos de los españoles se situaban entre los valores de complexión más bajos de Europa antes de la transición nutricional. Entre 1858 y 1913, la altura media creció solo 1,43 cm. En ese periodo hubo cambios significativos en la geografía antropométrica marcados por la configuración de una polaridad nutricional a las puertas de la I Guerra Mundial: las provincias del centro y del sur de país exhiben mayor incidencia de la malnutrición crónica que las provincias del arco Noreste, que disfrutan de ventaja relativa en términos nutricionales.Conclusión:las desigualdades territoriales que configuraron una geografía polarizada del estado nutricional en España pueden asociarse en parte a los cambios ambientales del periodo, caracterizados por el inicio de la modernización y la industrialización y, asimismo, por la privación derivada de las crisis agrarias, las enfermedades y el relativo atraso tecnológico. Se destaca la relevancia de la historia antropométrica para el estudio de los niveles de vida en poblaciones del pasado y del proceso de transición nutricional.

    Reseda lutea L. (Resedaceae) or Wild Mignonette is a widely distributed plant species. Pliny the Elder (AD 23-AD 79), a Roman scholar and naturalist, reported the use of R. lutea for reducing tumors in his Historia naturalis. Accounts of the beneficial effects of R. lutea in tumor treatment could also be found in the works of later authors, such as Étienne François Geoffroy (1672-1731) and Samuel Frederick Gray (1766-1828). However, to date no in vivo or in vitro evidence exists in support of the alleged tumor healing properties of R. lutea. The composition of autolysates obtained from different organs (root, flower and fruit) of R. lutea was investigated by GC and GC-MS analyses and IR, 1D and 2D NMR spectroscopy. These analyses led to the discovery of a new compound isolated in pure form from the flower autolysate. Autolysates and their major constituents were submitted to MTT-dye reduction cytotoxic assay on human A375 (melanoma) and MRC5 (fibroblast) cell lines. Mechanism of the cytotoxic effects was studied by cell cycle analysis and Annexin V assay. Benzyl isothiocyanate and 2-(α-l-rhamnopyranosyloxy)benzyl isothiocyanate were identified as the major constituents of the root and flower autolysates, respectively (the later represents a new natural product). These compounds showed significant antiproliferative effects against both cell lines, which could also explain the observed high cytotoxic activity of the tested autolysates. Cell cycle analysis revealed apoptosis as the probable mechanism of cell death. Tumor healing properties attributed to R. lutea in the pre-modern texts were substantiated by the herein obtained results. Two isothiocyanates were found to be the major carriers of the observed activity. Although there was a relatively low differential effect of the plant metabolites on transformed and non-transformed cell lines, one can argue that the noted strong cytotoxicity provides first evidence that could explain the long forgotten use of this

    The bee glue, commonly known as propolis, has been employed for medical purposes already in teh ancient world. More than 15 Greek and Roman authors report on the preparation and application of the so-called third natural product of the bees (besides honey and wax). Aristoteles described the fundamental issues of its biology in his 'Historia Animalium' correctly. The bulk of propolis is obtained from the barks of poplars. Once carried in the hives, the glue is used to stabilize the cells and honeycombs and to protect the bees against invaders and cold weather. Propolis has been chiefly employed for the preparation of ointment and plasters. For this purpose, the viscous raw material was purified, moulded and boiled. In most preparations, the bee glue was only one of many (up to 20) pharmacologically active constituents and came to five to 20% of the mixture. Only rarely, a single drug therapy was using propolis was carried out. The application of the glue was most successful in general surgery and casualties. In that respect, the ancient physicians took advantage of the anti-edematous and anti-infectious properties of the substance. Thus, it was used to treat bumps, indurations, and slow-healing wounds. Moreover, cataplasms against swollen cervical nodes and indurations of the female breast often contained propolis. Finally, bee glue proved successful for the treatment of chronic backache and pain in the hip as well as fresh injuries of muscles and tendons. In the sector of skin diseases, lichens and condylomata were found to respond well to propolis. ALl this indications have been a matter of several records. However, the successful use of propolis in diseases of the stomach and liver has ben reported solely by Alexander of Tralles (6th century AD). Not counting the internal diseases, the spectrum of indications for propolis has not substantially changed as compared to the classical antiquity. Interestingly, radiation therapists have adopted the ancient remedy and

The ground measurement results obtained indicate that soil properties and vegetation cover are the parameters of the physio-hydrological units that most influence the moisture of the soil. This relationship will permit a more simple delimitation of the physio-hydrological Units and a reduction of the number of sample points for the calibration/validation of SMOS products.

    (Wang et al., 2014). Significant differences (Kruskal-Wallis, p<0.05) were also found in AS between environments (UC>BS) but not between soil depths or hill-slope positions. In the first post-fire erosive rains occurred in the area (29-11-14), closest pluviometer (Sot de Ferrer: 4.5 km) registered a total daily rain up to 64.2 l m-2. In this event a total of 12.7 kg of sediment were collected (contributing area ≈0.25 ha), with a content of 252.6 gC kg-1 the total SOC transported or stored in the depositional zone can reach up to 3.2 kg. In the second erosive event (23-3-15: 103.2 l m-2), total sediment in the fences was 143.6 kg, with content of 112.2 gC kg-1, made a total SOC eroded of up to 16.1 kg. It is hypothesized that fire caused the homogenization of SOC content and AS in the different hill-slope positions, and only when erosion expose unburned organic matter to mineralization processes, SOC losses will increase in eroding sites, likely decreasing in transport and depositional ones. Ongoing work is related to the analyses of organic C in different soil fractions (determined by sieving and density) in order to understand C stabilization in post-fire soil, and its role in disaggregation and SOC redistribution by sediment in different hill-slope positions.

  12. Los manuales de quimica en Espana (1788--1845): Protagonistas, terminologia, clasificaciones y orden pedagogico

    Munoz Bello, Maria Rosa

    La presente tesis doctoral es una investigacion sobre los manuales de quimica utilizados en Espana de 1788 a 1845. Este trabajo proporciona una perspectiva general de un tema relevante en las ultimas decadas en Historia de la Ciencia, el estudio de los libros de texto. De acuerdo con las ultimas investigaciones realizadas en este terreno, el acto pedagogico es considerado como un proceso creativo, como espacio de encuentro de actores e intereses muy diversos, matizando las ideas defendidas por Thomas S. Kuhn. Recordemos que segun Kuhn, los libros de texto ofrecen una vision consensuada y normalizada del estado de la ciencia de su epoca, por lo que sus autores eliminan deliberadamente toda controversia y presentan asi una imagen distorsionada de la actividad cientifica. En cambio, se ha mostrado, por ejemplo, que en la ensenanza participan no solamente profesores y alumnos sino tambien otros muchos actores y todos ellos no unicamente con intereses puramente pedagogicos sino tambien con diversos intereses politicos y economicos que pueden conocerse a traves del estudio de los manuales. En esta tesis se pretende analizar los manuales de quimica en Espana desde 1788 hasta 1845. Para poder llevar a cabo la investigacion ha sido necesario precisar el objeto de estudio (libro de texto de quimica) durante el periodo estudiado (1788-1845) ya que no es adecuado adoptar la imagen actual de una disciplina que sufrio sustanciales cambios durante la epoca estudiada. Esta investigacion se centra en un momento especialmente importante para la quimica y que algunos historiadores han llegado a considerar "revolucionario". Durante estos anos se produjo un cambio importante en las teorias quimicas sobre la combustion y el concepto de elemento, asi como una reforma terminologica que originaron la aparicion de importantes controversias. Ademas, debido a la relacion de la quimica con otras disciplinas como la historia natural o la fisica ha sido necesario restringir el objeto de estudio

  13. Seven hundred years of peat formation recorded throughout a deep floating mire profile from Central Italy

    Floating mires are defined by the occurrence of emergent vegetation rooted in highly organic buoyant mats that rise and fall with changes in water level. Islands floating and moving on a lake naturally were already described by Pliny the Elder in his Naturalis historia almost two millennia ago. Actually, he devoted a whole chapter of Naturalis historia to "Of Islands Ever Floating and Swimming", reporting how certain isles were always waving and never stood still. The status of "flotant" has been defined transitory; in fact, these small isles often disappear, in most of the cases because of a transition from floating island to firm land during decades is likely to happen. That is why most of the floating islands described by Pliny the Elder (e.g., Lacus Fundanus, Lacus Cutiliensis, Lacus Mutinensis, Lacus Statoniensis, Lacus Tarquiniensis, Lydia Calaminae, Lacus Vadimonis) do not exist anymore. In the present study, peat formation and organic matter evolution were investigated in order to understand how these peculiar environments form, and how stable actually they are. In fact, it is hoped that peat-forming floating mires could provide an exceptional tool for environmental studies, since much of their evolution, as well as the changes of the surrounding areas, is recorded in their peat deposits. A complete, 4-m deep peat core was collected in July 2012 from the floating island of Posta Fibreno, a relic mire in the Central Italy. This floating island has a diameter of ca. 30 m, a submerged thickness of about 3 m, and the vegetation is organized in concentric belts, from the Carex paniculata palisade to the Sphagnum centre. Here, some of the southernmost Italian populations of Sphagnum palustre occur. The 14C age dating of organic sediments isolated from the sample at 385 cm of depth revealed that the island formed ca. 700 yrs ago (620±30 yr BP). The top 100 cm, consisting almost exclusively of Sphagnum mosses, show a very low bulk density (avg., 0.03±0.01 g cm-3

    The earliest examples of neurofibromatosis (in this case type 1, NF1) can be traced in the Ebers Papyrus (Ancient Egypt, 1.500 B.C.), in a Hellenistic statuette (Smyrna, 323 B.C.), in the coinage of the Parthians kings (247 B.C.) and in some 13th century monks' drawings. These earlier examples are somewhat less well defined as compared to the most recent better defined reports credited as having NF1 including an Inca child mummy (1480-1650 AD), Ulisse Aldrovandi's homuncio ("Monstrorum Historia", 1592 A.D.) with mosaic NF1 or the illustrations seen in the 18th century "Buffon's Histoire Naturelle" and "Cruveilhier's Anatomie Pathologique du Corps Human". The first English language report on NF1 was made by Akenside in 1768 and the first systematic review by Robert William Smith in 1849, while Virchow's pupil, Friedrich Daniel von Recklinghausen, in 1882, was the first to understand the origin of skin tumors and to name them neurofibromas. The touching story of Joseph C. Merrick (the "Elephant man," (who had Proteus syndrome and not NF1), in 1884, played an important role in the later misconception of NF1, as did the novel by Vicotr Hugo on the hunchback Quasimodo. The studies by van der Hoeve (1921), Yakovlev and Guthrie (1931), and Van Bogaert (1935), categorized "von Recklinghausen's" neurofibromatosis among the phakomatoses and the neurocutaneous syndromes. The first known mention of an acoustic neuroma (at autopsy) is attributed to Eduard Sandifort (1777 AD) while John H. Wishart made the earliest autoptic description of neurofibromatosis type 2 (NF2), in 1822, in a 21-year-old man with bilateral acoustic neuromas, who manifested signs since his infancy (Wishart subtype NF2). Smith likely described the first case of schwannomatosis in 1849. Older, Virchow, von Recklinghausen, and Verocay first classified "neuromas" and Masson and Penfield first used the word "schwannoma" taking it from Theodore Schwann's works. In 1903 Henneberg and Koch described NF2 in detail

    Resumen Introducción y objetivo: El TCE leve representa un problema sanitario de enorme interés debido a que un número significativo de enfermos con trauma leve desarrollará complicaciones potencialmente mortales. El objetivo de este estudio ha sido describir una serie amplia de pacientes adultos, mayores de 14 años, que sufren TCE leve, atendidos en el Hospital Universitario de Getafe, entre los años 2010 y 2015 (n = 2480), estudiar el perfil epidemiológico y analizar el diagnóstico y el tratamiento efectuados, así como establecer los principales factores pronósticos que influyen en el resultado final. Método: Se ha realizado un estudio retrospectivo, de revisión de historias clínicas, analizando los resultados con estudio estadístico bivariable y multivariable. Resultados: El TCE leve es más frecuente en varones, y el mecanismo causante más común en nuestro medio es el accidente de tráfico. Se propone un modelo de clasificación de pacientes según grupos de riesgo, que los subdivide en riesgo bajo, intermedio o alto, que se correlaciona bien con la probabilidad de desarrollar complicación intracraneal, y, consecuentemente, con el resultado final. Se discute la indicación de la radiografía simple de cráneo y de la Tomografía Computarizada (TC), así como del ingreso hospitalario para observación neurológica. Conclusiones: En este estudio, la presencia de focalidad neurológica en la exploración clínica, la edad, las alteraciones de la coagulación y la existencia de fractura en la radiografía simple se relacionan con mayor posibilidad de desarrollar lesiones traumáticas intracraneales y con peor pronóstico final. La escala de Glasgow para el Coma es deficitaria en la determinación del resultado final del paciente que sufre TCE, porque no considera variables tales como la amnesia o la pérdida de conocimiento, muy frecuentes en el traumatismo craneoencefálico leve.

There was no specific mention of any invasion coming directly from Africa (as testified by Pliny in Naturalis Historia VI, 195, VII, 28 29) nor from the Spanish peninsula. The centuries worst affected by this scourge were the XIV and XVI, and to a lesser degree, the XVII. More recently, man has been increasingly effective in combatting the locusts.

    Introducción: ante las nuevas implicaciones atribuidas a la vitamina D y la asociación con enfermedades tales como el cáncer, diabetes, enfermedades cardiovasculares, autoinmunes y mortalidad, no es de extrañar que se haya defendido la medición de los niveles de vitamina D en la población general. Sin embargo, no existen datos experimentales que demuestren la viabilidad y rentabilidad de la estrategia de cribado en la población y tampoco se ha comprobado la existencia de beneficios para la salud, por lo que en la actualidad solo es aconsejable la medida de 25 (OH) vitamina D en los grupos de personas de alto riesgo como indican las guías clínicas internacionales.Objetivos: analizar las peticiones de vitamina D comprobando si se adecuan a las guías clínicas.Métodos: realizamos un estudio descriptivo transversal en el Área de Salud de Badajoz (España) estudiando las peticiones de determinación de vitamina D durante 12 meses consecutivos (n = 3.907). En dicho estudio revisamos el diagnóstico de petición y la historia clínica del paciente para discriminar entre peticiones que se adecuaban a las guías clínicas y peticiones injustificadas. Por último, realizamos el estudio económico.Resultados: en nuestros resultados encontramos que casi un tercio de peticiones no se adecuaban a las guías clínicas, en patologías tales como diabetes, dislipemias e hipertensión en las que no está recomendada la medición de los niveles de vitamina D, por lo que suponía un exceso de gasto para el sistema sanitario. Gasto que se incrementa cada año, tanto es así que se ha producido un aumento en las peticiones de más del 1.000% en los últimos 6 años.Conclusiones: concluimos la necesidad de crear protocolos de petición de vitamina D que se ajusten a las guías clínicas hasta que existan más estudios experimentales sobre las nuevas implicaciones de la vitamina D y así conseguir una correcta utilización de los recursos económicos del hospital.

    A analise dos efeitos dos sismos mostra que a investigacao em engenharia sismica deve dar especial atencao a avaliacao da vulnerabilidade das construcoes existentes, frequentemente desprovidas de adequada resistencia sismica tal como acontece em edificios de betao armado (BA) de muitas cidades em paises do sul da Europa, entre os quais Portugal. Sendo os pilares elementos estruturais fundamentais na resistencia sismica dos edificios, deve ser dada especial atencao a sua resposta sob acoes ciclicas. Acresce que o sismo e um tipo de acao cujos efeitos nos edificios exige a consideracao de duas componentes horizontais, o que tem exigencias mais severas nos pilares comparativamente a acao unidirecional. Assim, esta tese centra-se na avaliacao da resposta estrutural de pilares de betao armado sujeitos a acoes ciclicas horizontais biaxiais, em tres linhas principais. Em primeiro lugar desenvolveu-se uma campanha de ensaios para o estudo do comportamento ciclico uniaxial e biaxial de pilares de betao armado com esforco axial constante. Para tal foram construidas quatro series de pilares retangulares de betao armado (24 no total) com diferentes caracteristicas geometricas e quantidades de armadura longitudinal, tendo os pilares sido ensaiados para diferentes historias de carga. Os resultados experimentais obtidos sao analisados e discutidos dando particular atencao a evolucao do dano, a degradacao de rigidez e resistencia com o aumento das exigencias de deformacao, a energia dissipada, ao amortecimento viscoso equivalente; por fim e proposto um indice de dano para pilares solicitados biaxialmente. De seguida foram aplicadas diferentes estrategias de modelacao nao-linear para a representacao do comportamento biaxial dos pilares ensaiados, considerando nao-linearidade distribuida ao longo dos elementos ou concentrada nas extremidades dos mesmos. Os resultados obtidos com as varias estrategias de modelacao demonstraram representar adequadamente a resposta em termos das curvas

    After the publication of the SISRA (CERESIS-1985) regional project, a unified catalog of seismic parameters and intensities for South America, researchers in historical seismicity have continued advancing on different scales in the area of this study of seismic hazard. The most important initiatives carried out in this area in Colombia and Venezuela can be grouped as follows: a) Reviews of destructive earthquakes in national and international historic archives, principally by Altez and FUNVISIS in Venezuela and Espinosa, Salcedo, and Sarabia et al in Colombia, leading to the preparation of seismologic catalogues, scientific and dissemination articles, reports, books, among others. b) Organization and systematization of historic information to develop public domain data bases and information, specifically the Historic Seismologic Teleinformation System in Venezuela, carried out between 2004 and 2008 under the coordination of Christl Palme and accessible on-line: http://sismicidad.ciens.ula.ve. As well, the "Historia Sísmica de Colombia 1550-1830" (Seismic History in Colombia 1550-1830) data base, in CD-ROM, by Espinosa Baquero (2003) and the historic seismicity information system of Colombia (Servicio Geológico Colombiano-Universidad Nacional de Colombia), published on the internet in 2012: http://agata.ingeominas.gov.co:9090/SismicidadHistorica/. c) Macroseismic studies for the development of intensity attenuation equations and the quantification and revaluation of basic historic earthquake parameters using isoseismal maps (Rengifo et al., Palme et al., Salcedo et al., among others) and procedures such as Boxer and Bakun & Wentworth (Palme et al., Dimaté, among others), which have produced significant changes in the parameters of some of the large earthquakes. d) Symposiums of researchers to promote interest and development in the discipline, including Jornadas Venezolanas de Sismología Histórica (Venezuelan Congress of Historical Seismology), held

    Hyphessobrycon with 129 valid species, is a genus of fish that has a great diversity of species in the Neotropical ichthyofauna, reaches its greatest diversity in the Amazon basin with about 70% of these species, is highly desired by hobbyists because of their beauty and color, and are still meeting new species. We analyzed specimens from the Departamento de Ictiología, Museo de Historia Natural de la Universidad Mayor de San Marcos, Lima, Perú (MUSM); and measurements of the specimens were taken point to point with digital calipers. Observations of bone and cartilage structures were made on cleared and stained (C&S) samples. The morphometric relationships between species using 21 variables were explored using a principal component analysis (PCA). Here we describe two new species, Hyphessobrycon taphorni and H. eschwartzae from the Madre de Dios River drainage, Peru. Hyphessobrycon taphorni sp. n. can be distinguished by the number of dorsal-fin rays (iii, 8), by the number of: pored lateral-line scales (4-5), teeth in the outer premaxillary row (1-2), teeth in the inner premaxillary row (7-8), by: the caudal-peduncle length (11.4-16.4% SL), number of lateral scales (28-29, except from H. loretoensis which has 29-30) and absence of a humeral spot (vs. present), it differs from H. loretoensis by the number of: scales between the lateral line and the anal fin origin (4 vs. 3) and maxillary teeth (2 vs. 3-4), and it differs from H. agulha by the number of branched pectoral-fin rays (11-12 vs. 9-10). Hyphessobrycon eschwartzae sp. n. is distinguished by the number of: simple anal-fin rays (iv), teeth on the dentary (13-15), teeth in the inner premaxillary row (6), teeth in the outer premaxillary row (3, except from H. heterorhabdus and H. loretoensis which have 3-4); it differs from H. loretoensis by the number of: pored lateral-line scales (7 vs. 9-10), scales between the lateral line and the dorsal-fin origin (5 vs. 3-4); it differs from H. agulha in the number of

    This work is presented as a theoretical essay on some facts from the history of astronomy analyzed according to the theory of reflective abstraction developed by Jean Piaget and collaborators (1970). Its aim is to understand the reasons that led to different astronomers, at the same historical period and culture, to "see" quite different evidences about the same phenomenon. In addition, we intend to facilitate the understanding of science as a human construction, subject to a time epoch and the ways of understanding of each scientist. Este trabajo se presenta como un ensayo teórico sobre algunos hechos históricos de la astronomía, analizados según la teoría de la abstracción reflexionante de Jean Piaget y sus colaboradores (1970). Se trata de comprender los motivos que llevaran a distintos astrónomos, de una misma época histórica y cultural, a "ver" diferentes evidencias sobre un mismo fenómeno. Además, se intenta posibilitar la comprensión de la ciencia como construcción humana, la cual es condicionada por su momento histórico y por las creencias y las formas de entender de los científicos.

  5. The case for policy-relevant conservation science

    PubMed Central

    Rose, David C

    2015-01-01

    Drawing on the “evidence-based” (Sutherland et al. 2013) versus “evidence-informed” debate (Adams & Sandbrook 2013), which has become prominent in conservation science, I argue that science can be influential if it holds a dual reference (Lentsch & Weingart 2011) that contributes to the needs of policy makers whilst maintaining technical rigor. In line with such a strategy, conservation scientists are increasingly recognizing the usefulness of constructing narratives through which to enhance the influence of their evidence (Leslie et al. 2013; Lawton & Rudd 2014). Yet telling stories alone is rarely enough to influence policy; instead, these narratives must be policy relevant. To ensure that evidence is persuasive alongside other factors in a complex policy-making process, conservation scientists could follow 2 steps: reframe within salient political contexts and engage more productively in boundary work, which is defined as the ways in which scientists “construct, negotiate, and defend the boundary between science and policy” (Owens et al. 2006:640). These will both improve the chances of evidence-informed conservation policy. El Caso para la Ciencia de la Conservación con Relevancia Política Resumen A partir del debate “con base en evidencia” (Sutherland et al. 2013) versus “informado con evidencia” (Adams & Sandbrook 2013), debate que se ha vuelto prominente en la ciencia de la conservación, argumento que la ciencia puede ser influyente si mantiene una referencia dual (Lentsch & Weingart 2011) que contribuya a las necesidades de quienes hacen la política a la vez que mantiene un rigor técnico. En línea con dicha estrategia, los científicos de la conservación cada vez reconocen más la utilidad de construir narrativas con las cuales pueden mejorar la influencia de sus evidencias (Leslie et al. 2013; Lawton & Rudd 2014). Sin embargo, sólo contar historias rara vez es suficiente para influir sobre la política; en su lugar, estas

    The article presents the history of transforming one of the oldest places in Hamburg - the Cathedral Square (Domplatz), as well as the influence of historical factors on the conception behind its development. A tumultuous history, especially the consequences of World War II, has led to the diminishment of its historical significance. The undeveloped quarter once occupied by a prehistoric settlement and St. Mary's Cathedral functioned as an urban wasteland and a parking lot for a few decades. Attempts to change this state of things proved unsuccessful. Currently, revitalization works aimed at renewing city centers are being realized more and more often, in order to make them become competitive against the overly developed suburbs and so as to return to the tradition of forming a European city. The green area established in the Cathedral Square in 2009 was to be built-up initially, but owing to the objection of urban communities - conservators, archeologists, politicians, as well as public opinion, such plans were abandoned. The proposed and realized current form of the square reflects the historical background of the city and honors the importance of the location. The article refers the described example to the Recommendation signed in 2011 by the UNESCO General Conference regarding Historic Urban Landscape. W referacie przedstawiono historię przekształcania się jednego z najstarszych najstarszych miejsc Hamburga - Placu Katedralnego (Domplatz) oraz wpływ czynników historycznych na koncepcję jego zagospodarowania.

    The Italian territory is rich in archaeological heritage, located in hilly, plain or coastal areas. Frequently, it is possible to find only the remains of ancient cultures, villages and sparse houses dating back many centuries. Therefore, no other documentation but the remains themselves can give information about both the existence and the events that eventually determined the end of historical sites, caused either by abandonment or destruction. The causes that can determine the abandonment or the destruction can be various, and may be due to anthropic and/or natural causes, and only in very few cases documents or pictures of these events are preserved. Anthropic causes can be diverse: wrong design and/or building schemes of the structure or of the foundation, wars etc. Natural causes could be variuos as well, and can be related to the environmental context of the site. For example, in mountainous areas the main causes can be landslides, snow avalanches, soil creep affecting the foundations. In plain areas floods are the main process leading to the disruption of hamlets. Along the coast tsunamis are to be considered. Other natural causes could be earthquakes or climate changes. In the Emilian Apennines, near Sassuolo (Modena, Italy), a Roman villa dated from the I century B.C. to the VI century A.D. has been excavated along a gentle slope. The villa can be divided in four different buildings from successive periods. During the first period of life of the villa (I century B.C.-I century A.D.) a destructive event caused the abandonment of this building, whose walls and mosaic floors have been destroyed in a odd way. Which was the cause of this destruction? An earthquake, a human error in construction or a landslide? What makes this question even more interesting is the probable relation of this event with an ancient source (Pliny the Older, Naturalis Historia II, 199) who remembers how in the Modena area a "portentum terrarum" (earthquake) and the collision of two

    The curious sight of an island floating and moving on a lake naturally, already described by Pliny the Elder in his Naturalis historia (AD 77-79), fascinated people from time immemorial. Floating mires are defined by the occurrence of emergent vegetation rooted in highly organic buoyant mats that rise and fall with changes in water level. Peat-forming floating mires could provide an exceptional tool for environmental studies, since much of their evolution, as well as the changes of the surrounding areas, is recorded in their peat deposits. A complete, 4-m deep peat core was collected in July 2012 from the floating island of Posta Fibreno, a relic mire in the Central Italy. This floating island has a diameter of ca. 30 m, a submerged thickness of about 3 m, and the vegetation is organized in concentric belts, from the Carex paniculata palisade to the Sphagnum centre. Here, some of the southernmost Italian populations of Sphagnum palustre occur. The 14C age dating of macrofossils removed from the sample at 360 cm of depth revealed that the island probably formed more than 500 yrs ago (435±20 yr BP). In the present work, we show preliminary results regarding the evolution of the organic matter along the first, ombrotrophic 100 cm of depth, hoping also to provide some insight into the possible mechanism of the evolution of this floating island. The 100 cm monolith was collected using a Wardenaar corer and cut frozen in 1-cm layers. It consists almost exclusively of Sphagnum mosses, often spaced out, in the top 20-30 cm, by leaves of Populus tremula that annually fell off. This section shows a very low bulk density, ranging from 0.017 and 0.059 g cm-3 (avg. value, 0.03±0.01 g cm-3), an average water content of 96.1±1.1%, and a gravimetric water content ranging between 14.3 and 41.5 gwater gdrypeat-1. The pH of porewaters was in the range 5-5.5. The C content along the profile ranged between 35 and 47% (avg., 41±1%), whereas the N between 0.3 and 0.9% (avg., 0.6±0

    In many of her literary works, the writer and columnist Eliza Orzeszkowa (1841-1910), who was twice nominated for the Nobel Prize in literature (1905, 1909), depicted the life of the Polish society in the eastern lands of the former Polish-Lithuanian Commonwealth in the second half of the 19th century. A great lover of nature, Orzeszkowa appreciated the botanical knowledge of the local rural population in the vicinities of Grodno. She combined attempts to master that knowledge with her other great passion, that of investigating folk culture, and was always ready to listen to what women who were village herbalists had to tell her about medicinal plants, and about the customs and legends connected with the medical practices based on herbal remedies. She then passed on the information to botanists for scientific verification. Orzeszkowa's naturalist and ethnographic fascinations led her to write a cycle of articles on "The people and flowers on the Niemen river", published in 1888-1891 in the ethnographic-tourist magazine "Wisła". This collection of articles has been analysed not only by historians of literature, but also, since 1985, by historians of science. The first analysis was conducted at the Section for the History of Pharmacy of the Institute of the History of Science of the Polish Academy of Sciences. This yielded Ewa Kamińska's study: Ziołoznawstwo i ziołolecznictwo w publikacjach etnograficznych Elizy Orzeszkowej [The knowledge of herbs and medicine based on herbal remedies in the ethnographic publications of Eliza Orzeszkowa] published as part of the Institute's Historia leków naturalnych [History of natural medicines], ed. Barbara Kuźnicka, vol. I: Zródła do dziejów etnofarmacji polskiej [Sources for the history of Polish ethnopharmacy], Warszawa 1996, pp.25-88. The subject-matter of the publication aroused much interest among historians of pharmacy from Poznań. The first sign of that interest could be seen in the article by Jan Majewski and S

    Clinical information models are formal specifications for representing the structure and semantics of the clinical content within electronic health record systems. This research aims to define, test, and validate evaluation metrics for software tools designed to support the processes associated with the definition, management, and implementation of these models. The proposed framework builds on previous research that focused on obtaining agreement on the essential requirements in this area. A set of 50 conformance criteria were defined based on the 20 functional requirements agreed by that consensus and applied to evaluate the currently available tools. Of the 11 initiative developing tools for clinical information modeling identified, 9 were evaluated according to their performance on the evaluation metrics. Results show that functionalities related to management of data types, specifications, metadata, and terminology or ontology bindings have a good level of adoption. Improvements can be made in other areas focused on information modeling and associated processes. Other criteria related to displaying semantic relationships between concepts and communication with terminology servers had low levels of adoption. The proposed evaluation metrics were successfully tested and validated against a representative sample of existing tools. The results identify the need to improve tool support for information modeling and software development processes, especially in those areas related to governance, clinician involvement, and optimizing the technical validation of testing processes. This research confirmed the potential of these evaluation metrics to support decision makers in identifying the most appropriate tool for their organization.

En esta última dimensión veremos cómo las ideas positivistas tuvieron gran importancia en la formación de maestros impartida en las Escuelas Normales. Estableceremos también la relevante influencia del contexto socio-histórico en el desarrollo de la astronomía, y, a su vez, apreciaremos que esta última fue un actor social fundamental en la Historia Argentina. Domingo F. Sarmiento acreditava que a astronomia de Copérnico fosse uma das disciplinas científicas fundamentais para a formação de um cidadão "moderno". Neste trabalho estudaremos astronomia a partir de duas perspectivas: a científica e a educacional Nosso estudo será desenvolvido para a Argentina no século XIX, a partir da iniciativa de Bernardino Rivadavia, em 1821, que estabeleceu um observatório astronômico em Buenos Aires, até as primeiras atividades dos observatórios de Córdoba e La Plata. Em ambas as perspectivas, científica e educativa, vamos analisar a influência das ideias positivistas. Discutiremos como existiram diferenças epistemológicas entre eles, o Observatório de Córdoba orientado de acordo com o positivismo francês, e La Plata, de acordo com o positivismo alemão. Ambos os observatórios tinha uma atitude diferente em relação à educação. As ideias positivistas foram muito importantes para treinar professores do ensino primário na Argentina. Nós iremos enfatizar a importante influência do contexto sócio-histórico na astronomia, já que esta ciência foi um importante ator social na história da Argentina.

    exilio: el uso de productos vegetales, animales y minerales con fines de perfumería, cosmética y curativos de la piel entre los refugiados saharauis del Sáhara Occidental. Antecedentes Durante la última década ha habido un creciente interés en los estudios etnobiológicos de los conocimientos y prácticas de las personas que migran. Dentro de esta tendencia, los estudiosos han prestado relativamente menor atención a las personas desplazadas y a los refugiados: a la pérdida, el mantenimiento y la adaptación de sus conocimientos etnobiológicos, y su importancia para el bienestar de los refugiados. Este estudio se centra en los cosméticos y remedios para curar problemas de la piel tradicionalmente utilizados por los refugiados saharauis en los campamentos de desplazados al sudoeste de Argelia. Métodos Los métodos de investigación que se utilizaron son: una encuesta estructurada con 37 familias de refugiados, entrevistas semi-estructuradas con 77 refugiados, 24 entrevistas retrospectivas con refugiados e informantes conocedores, y una colección de muestra de las plantas y productos citados. Resultados Se registró el uso de 55 especies vegetales, nueve especies animales, y seis productos minerales utilizados en tres principales categorías de usos: 1) Recursos contra los problemas de salud característicos del entorno desértico donde una vez vivieron los saharauis como nómadas y donde ahora viven como refugiados (por ejemplo problemas en los ojos); 2) Remedios para heridas que reflejan la historia reciente de guerra de guerrilla de los nómadas saharauis; y 3) Cosméticos y productos utilizados para el cuidado del cuerpo, decoración y perfumes (por ejemplo, atención al cabello, limpieza de dientes, uso del henna) y como aromatizantes del aire al interior de las tiendas, que son ampliamente utilizados en la vida y las prácticas sociales cotidianas de los refugiados. Conclusiones En la discusión, se analizan los cambios que se han producido en los patrones

    The 18th volume of the Acta Historica Astronomiae is at the same time the sixth collection of essays on the history of astronomy ("Beitræge zur Astronomiegeschichte, Band 6"), edited by the historians of astronomy W.R. Dick (Potsdam) and J. Hamel (Berlin). Besides a few short notices and book reviews, the book contains eight major articles, which deal with astronomical topics covering the time from the 16th to the 19th centuries. The first article by Michael Weichenhan (Berlin) deals with "the invention of the disk-shaped earth: a chapter of Copernican apologetics". The author shows that the concept of a "disc-shaped Earth" was by no means widespread in the middle ages, but restricted to the father of the church Lactantius and some adherents. Nevertheless, it was used by adherents of Copernicus to show the absurd consequences of a strictly literal biblical interpretation -- here concerning the Earth's shape, disc versus sphere, there the geocentric versus the heliocentric system. This thorough philosophical study is followed by two very short articles. "The measuring accuracy of Tycho's large sextant" by Johann Wünsch investigates O-C values of planet-star distances, as based on Tycho's observations as published in the Historia Coelestis (a compilation, which is also based on Tycho's manuscripts, and published in Regensburg in 1672). The result is that standard deviations are 80 arcseconds for Saturn and 89 arcseconds for Jupiter and Mars, an unexpectedly poor result in view of the general opinion that Tycho was famous for his precision work. "The astronomer Christoph Grienberger and the Galilei trial" by Franz Daxecker deals with a Jesuit astronomer who was both the disciple and successor of the mathematician-astronomer Christopher Clavius at the Collegium Romanum. While he was inclined to Galilei early on, he was forced to propagate Aristotelian doctrine. The brief article is very concise, but extremely tiresome to read (3 pages of pure text are embellished by

    In the paper the first attempt at the definition of a model to assess the impact of a range of different volcanic hazards on the building structures is presented. This theoretical approach has been achieved within the activities of the EXPLORIS Project supported by the EU. A time history for Sub-Plinian I eruptive scenario of the Vesuvius is assumed by taking advantage of interpretation of historical reports of volcanic crises of the past [Carafa, G. 1632.

    ógicos, así como las desviaciones relacionadas con diferencias en la estructura de la roca y, presumiblemente, en las historias de deformación. Se profundizó en la relación entre la frecuencia de los manantiales y las estructuras de la roca por medio de la Determinación Espectral, que es un modelo introducido en el presente estudio. Los datos de entrada son las frecuencias de los manantiales y la longitud de las fracturas en cada dominio geológico, además de los ángulos entre las direcciones de las fracturas y la orientación actual del campo de tensiones. Los resultados del modelo incluyen las denominadas densidades intrínsecas, parámetro que cuantifica la existencia de manantiales en función de factores como el tipo de fractura y el régimen y edad de deformación asociados. Las densidades mayores (12,2 manantiales por kilómetro de lineamiento) fueron atribuidas a fracturas jóvenes de cizalla causadas por deformación frágil, y las menores (valor 0,1) con fracturas antiguas y dúctiles. La Determinación Espectral también relaciona cada clase de orientación con un parámetro estructural dominante: donde la existencia de fracturas está dominada por el campo actual de tensiones, la clase es paralela a la orientación presente de dicho campo; donde domina la longitud de las fracturas, sigue la dirección de las fallas normales de gran escala que atraviesan la región.

    historias planetarias. La Tierra es principalmente generosa con la recarga de la mayoría de reservorios de aguas subterráneas a partir de amplia precipitación reconocida en condiciones transitorias calientes y heladas, tal y como aparece en los registros fósiles y geológicos. Por otro lado, Marte se encuentra principalmente en una etapade cámara de hielo la cual es interrumpida por actividad de tipo endogénico. Esta actividad pone en funcionamiento catastróficamente ciclos hidrológicos de vida corta y perturbaciones climáticas asociadas. Acuíferos regionales en las montañas de Marte que se desarrollaron en el pasado en condiciones similares a la Tierra distribuyen agua a las planicies del norte. El agua ha sido transportada hacia el sur de la región polar durante cambios en el clima inducidos por actividad endogénica y/o cambios en los parámetros orbitales de Marte. Venus muy probablemente tuvo una hidrósfera caliente durante cientos de millones de años, antes de que se desarrollara su atmósfera y superficie actual extremadamente caliente. Subsecuentemente, Venus perdió su hidrósfera a medida que la luminosidad solar aumentó y un efecto de invernadero húmedo escapatorio se llevó a cabo. Océanos subsuperficiales de composición agua o amoniaco-agua, inducidos por fuerzas de marea y calentamiento radiogénico, probablemente ocurren en los satélites más grandes como Europa, Ganimeda, Callisto, Titan y Triton. Las fuerzas de marea que operan entre los cuerpos pequeños del sistema solar externo podrían también promover la fusión de hielo y la estabilidad de líquido interno-aguas de los océanos.

    discutir los resultados clínicos de 7 años de trabajo con 2116 mujeres intervenidas en tres hospitales del país. Métodos Estudio retrospectivo de cohortes utilizando datos tomados de historias clínicas de reparaciones de fístula realizadas entre el 2007 y el 2013. Los datos del estudio se revisaron durante el periodo entre Abril y Agosto 2014. Resultados La mayoría de las 2116 mujeres que se sometieron a la reparación quirúrgica tenían una fistula vesico-vaginal (n = 2045, 97%) y 3% tenían una fístula recto-vaginal o una combinación de ambas. En general, 1748 (83%) tenían la fístula cerrada y eran continentes inmediatamente después de la cirugía. En el momento del alta, 1795 mujeres (85%) tenían la fistula cerrada y 1680 (79%) estaban secas, es decir que ya no perdían orina y/o heces. 115 (5%) continuaron teniendo incontinencia residual a pesar de que la fistula estaba cerrada. El seguimiento a los tres meses se completó para 1663 (79%) mujeres, de las cuales 1405 (84.5%) tenían la fistula cerrada y 80% eran continentes. Un 21% fueron perdidas durante el seguimiento. Conclusión La reparación rutinaria programada de la fístula obstétrica en lugares con pocos recursos puede dar buenos resultados. Sin embargo, se requieren más esfuerzos para resolver la pérdida durante el seguimiento, mantener los resultados y prevenir la aparición y/o reaparición de la fístula. PMID:25706671

    'élargissement de l'UE). Dans la discussion, il est aussi argumenté que la correspondance plus étroite entre la représentation idéologique de ces attitudes dans les sociétés polonaise et occidentale peut être due au fait que le communisme a moins réussi à pénétrer la mentalité politique en Pologne qu'en Ukraine. La presente investigación somete a prueba la validez de un modelo de dos dimensiones, cultural y económico de ideología de derecha, así como las relaciones entre estas dimensiones y actitudes hacia temas políticos recientes. Las opiniones sobre el ambiente, la guerra al terror, y la ampliación de la Unión Europea se seleccionaron como actitudes representativas contemporáneas. Se investigaron las preguntas de investigación en muestras flamencas (N = 176), polacas (N = 93) y ucranianas (N = 93). Los resultados revelan que subyacen dos dimensiones al espectro ideológico en todas las muestras, una se refiere al conservadurismo cultural y al autoritarismo de derecha (AD), y otra que se refiere al conservadurismo económico y a la orientación de dominancia social (ODS). A pesar de que los estudios en muestras occidentales han ilustrado ampliamente la validez de las diferencias entre estas dimensiones ideológicas, la réplica de estos estudios en países anteriormente comunistas contribuye a su validez y generalidad, porque estos países poseen una cultura e historia política específica. Sin embargo, también se obtuvieron diferencias interculturales importantes respecto a la representación de las actitudes contemporáneas en este espacio ideológico de dos dimensiones. En tanto que la guerra al terror se relacionó de manera significativa a la dimensión de derecha en todas las muestras, las relaciones para el ambientalismo y la ampliación de la Unión Europea dependieron de la muestra. Las diferencias interculturales se explican en términos de la notoriedad del tema (relaciones no significativas contra significativas en el caso del

Administrativamente, la responsabilidad por la evalucion debe estar cerca al director, se debe tomar provisiones para obtener informes regulares (meneulaes) y especiales dirigidos a preguntar sobre política. El corolario es que el jefe de evaluación debe tener la confianza del director y debe estar al día en cuanto a las decisiones sabre la politics a seguir. Su trabajo consiste en extractar los aspectos principales que funcionan bien y los no operantes.

    souvent l'occasion de discuter de ces questions, nous présentons ici un survol général de quelques techniques de génération de telles propriétés se focalisant sur une seule d'entre elles, la perméabilité des roches. Nous expliquons d'abord quels sont les raisons qui engagent à tenter de décrire la variabilité spatiale, puis nous illustrons trois méthodes pour le faire, la méthode géostatistique, la méthode Booléenne et la méthode génétique. Nous présentons leurs avantages et inconvénients respectifs, et donnons l'état actuel de leur développement. Ces méthodes constituant un domaine de recherche actif, et la place étant ici limitée, ce survol est nécessairement incomplet, mais nous espérons qu'il encouragera l'essor de nouvelles idées et de nouvelles approches. Resumen Sabemos desde hace tiempo que las propiedades del subsuelo son altamente variables espacialmente. Hemos aprendido que esta variabilidad es debida a la extrema complejidad y variabilidad temporal de los procesos responsables de la formación de la corteza terrestre, desde la tectónica de placas a la erosión, transporte de sedimentos y deposición, así como a efectos mecánicos, climáticos y diagenéticos. Como geólogos, hemos aprendido a "leer" esta compleja historia en las rocas y a cómo tratar de extrapolar en el espacio lo que ya sabemos. Como físicos, aprendimos después que para estudiar los procesos en este tipo de medios debemos aplicar las leyes de la mecánica de los medios continuos. Como matemáticos que usan métodos analíticos, hemos aprendido que debemos simplificar el medio dividiéndolo en un número menor de unidades, como serían los acuíferos y acuitardos, y describiendo sus propiedades mediante valores equivalentes (constantes). En los últimos años, como modelistas, también hemos aprendido que tenemos la libertad de "discretizar" esta realidad compleja y describirla como un conjunto de pequeñas cajas homogéneas de medio continuo, cada una con
