Rapid Evolution of Volatile CO from the Protostellar Disk Stage to the Protoplanetary Disk Stage
Authors: Zhang Ke , Schwarz Kamber R. , Bergin Edwin A. 
Published: March 2020

Abstract
Recent observations show that the CO gas abundance, relative to H2, in many 1–10 Myr old protoplanetary disks may be heavily depleted by a factor of 10–100 compared to the canonical interstellar medium (ISM) value of 10−4. When and how this depletion happens can significantly affect compositions of planetesimals and atmospheres of giant planets. It is therefore important to constrain whether the depletion occurs already at the earliest protostellar disk stage. Here we present spatially resolved observations of C18O, C17O, and 13C18O J = 2−1 lines in three protostellar disks. We show that the C18O line emits from both the disk and the inner envelope, while C17O and 13C18O lines are consistent with a disk origin. The line ratios indicate that both C18O and C17O lines are optically thick in the disk region, and only the 13C18O line is optically thin. The line profiles of the 13C18O emissions are best reproduced by Keplerian gaseous disks at similar sizes as their mm-continuum emissions, suggesting small radial separations between the gas and mm-sized grains in these disks, in contrast to the large separation commonly seen in protoplanetary disks. Assuming a gas-to-dust ratio of 100, we find that the CO gas abundances in these protostellar disks are consistent with the ISM abundance within a factor of 2, nearly one order of magnitude higher than the average value of 1–10 Myr old disks. These results suggest that there is a fast, ∼1 Myr, evolution of the abundance of CO gas from the protostellar disk stage to the protoplanetary disk stage.
Le symptôme en acte
Authors: Kaltenbeck Franz 
Published: March 2020

En 1936, Samuel Beckett se rend à Brunswick pour voir l’ Autoportrait de Giorgione. Il admire ce tableau et partage l’angoisse de la figure qui le regarde. Aussitôt, son symptôme est mobilisé, plus tard, sa création. Cet article révèle, grâce aux schémas optiques de Lacan, l’effet de l’art de Giorgione sur l’auteur irlandais, et montre que l’expérience de Brunswick s’est répercutée dix ans plus tard quand Beckett a écrit sa nouvelle « Le Calmant ».
« On dirait un môme »
Authors: Kaltenbeck Franz 
Published: March 2020

L’enfant n’est pas seulement le pôle d’attentes ou le support narcissique de ses parents, ce « revenant » qui leur permet d’accéder à l’immortalité, selon Freud. Pour les grands dramaturges, il est aussi celui qui révèle le destin (Shakespeare, Macbeth ), un messager d’une rencontre manquée (Beckett, En attendant Godot ) ou le signifiant forclos de la vie (Beckett, Fin de partie ). Dans le réel cru, il peut aussi devenir la victime d’un meurtre oubliée par toute la société. Nous consacrerons notre article à ces fonctions dramatiques et trop réelles de l’enfant, peu abordées par la psychanalyse.
À partir de Louis-René des Forêts et Samuel Beckett, écrits de vieillesse et vieillesses écrites
Authors: Kaltenbeck Franz 
Published: March 2020

Dans la description poétique de la vieillesse et de la mort, l’écrivain fait l’expérience de l’impossible à dire et donc du réel. L’acte d’écrire constitue une sublimation, au sens lacanien, de l’échéance tragique. L’assomption de la mort se déroule lors de la création d’une littérature crépusculaire. Or cette création résulte d’une lutte. En effet, écrire sur la vieillesse ou pendant la vieillesse nécessite de se confronter à la mort que d’aucuns refoulent. Louis-René des Forêts, dans ses textes autobiographiques Ostinato (1972) et Pas à pas jusqu’au dernier (2000), écrit ses ultimes moments de vie alors que ses doigts se paralysent. Dans le dramaticule Solo (1977), Samuel Beckett noue la naissance à la mort et à la lettre. Les écrits des deux auteurs constituent une lutte face à la mort pour en cerner l’intransmissible.

A critical Appraisal of consumer health literature in Tamil print news media in Sri Lanka
Authors: Sri Ranganathan S. , Balasubramaniam R. , Thayakaran M. , Thiruvarangan S. , Vahine N. 
Published: March 2020

Objective: This study was designed to critically appraise the consumer health literature (CHL) appearing in Tamil print news media (lay press or newspapers) in Sri Lanka Methods: This cross-sectional descriptive study critically appraised the CHL appeared in National and regional Tamil newspapers published in Sri Lanka during a period of three months. We conducted a pilot study for a period of one week to identify all the Tamil newspapers published in Sri Lanka and also to determine the variables that can be used to appraise the CHL. CHL was defined as materials giving information on health related matters. Health advertisements and information on cosmetics were excluded. Two investigators independently went through all the target newspapers to identify and separate the CHL. Subsequently, using a pre-tested checklist, two investigators independently appraised the CHL. In case of major disagreement between the two investigators, decision was made by consensus. Results: There were 633 CHL in 600 newspapers: Common topics included non-communicable diseases (25%), reproductive health (13%) and food habits (12. 6%). Topics related to National public health campaigns, official health promotion messages, communicable diseases, medicines, vaccines, tobacco and alcohol were very minimal. Names and designation of the author/source was available only in 37.6%: Specialists, doctors, medical academics and medical students have authored the majority (79%). 591 CHL had some form of pictures, but in 70%, the pictures were assessed to be irrelevant to the subject matter. Two-thirds were on very socially valuable topics whereas content was appraised to be of poor scientific merit and unreliable in 54%. Conclusions: Tamil newspapers are underutilized in disseminating important health messages to public and there is an urgent need to nurture medical journalism in Sri Lanka.
Anatomical variations of femoral vessels
Authors: Niranjan Romini , Udhayakumar Sivananthini 
Published: March 2020

Femoral triangle is an important site for various clinical procedures. Knowledge about anatomical variations of femoral vessels is important to prevent inadvertent damage during surgical procedures and for successful arterial and venous cannulation. It is an incidental finding in which profunda femoris artery originated just 1cm below inguinal ligament from lateral aspect of femoral artery (FA) in left femoral region of a middle aged Sri Lankan man which was observed during routine dissection. It was observed that FA crossed superficially over femoral vein (FV) in upper part of femoral triangle and FV was lying deep to FA in most part of femoral triangle. FV catheterization is necessary when there is no visible peripheral vein for cannulation or when rapid access to a large vein is needed. Complications may arise from accidental puncture of neighbouring structures. Ultrasonography should be used particularly for more difficult femoral vascular access. Even though variations are mostly incidental findings and being of general anatomical interest, knowledge of these variations appears to be mandatory for planning surgery and vascular interventions.
The Ego’s Attention and the Therapist’s Attention to Reality in Freud. At the Threshold of Ethics
Authors: Montoya Ana Lucía 
Published: March 2020

This article aims to show that the practice of attention can create an openness to the truth, from where ethics arises. It does so by exploring the role attention plays, according to Ricoeur, in Freud’s thought. Ricoeur shows how in the first stage of Freud’s thinking – that of the Project of a Scientific Psychology – attention is one of the instances in which a purely mechanical quantitative explanation can be questioned. Further on, with the introduction of narcissism, Ricœur shows that attention, insofar as it opens a space for the “wounding truth,” opposes narcissism. Finally, the article explains how in the therapeutic setting an attentional epochē allows the therapist to be “the reality principle in flesh and in act,” so that the ego can gain control. According to Ricœur, this non-judgmental gaze opens a space of truthfulness for the patient’s self-knowledge which, although not being the totality of ethics, constitutes its threshold.
Replacing Final Exams with Open-Ended Course Projects in Engineering Education
Authors: Goorts Kevin 
Published: March 2020

Over the last twenty years, assessment methods in Engineering education have shifted to focus on evaluating desired learning outcomes. Both Mills and Treagust (2003) and Olds, Moskal, and Miller (2005) credit the paradigm shift to accreditation procedures that report program inputs and document achievement of learning objectives. High-stakes final exams have been, and still are, widely used in Engineering education as the primary means to evaluate student learning (Flores, Veiga Simão, Barros, & Pereira, 2015). Although considered objective and efficient for large class sizes, Knight (2002) points to shortcomings associated with final exams including ineffectiveness at evaluating certain types of outcomes and a distorting effect on the taught curriculum. However, overcoming these shortcomings is possible through project-based learning and open-ended course projects.
Project-based learning is a form of experiential learning that gives students the opportunity to apply theoretical concepts while developing higher-order skills (e.g., critical thinking, synthesis, and evaluation) and soft-skills (e.g., communication, management, and teamwork; Mills & Treagust, 2003). Based on three different experiences with large-scale open-ended projects, Daniels, Faulkner, and Newman (2002) conclude that the use of course projects enhances student learning while better preparing them for their future careers. Flores et al.’s (2015) findings support this notion by demonstrating that students perceive assessment methods that require active involvement as more fair and effective.
This workshop aims to increase awareness around the importance of assessment and highlight that high-stakes final exams, although widely used, have a number of flaws that may bias evaluation and impact student learning. The workshop’s main goal is to introduce project-based learning as an alternative to final exams and develop skills to identify where and how instructors can use open-ended course projects effectively.
LIGHTWEIGHT ELASTOMER COMPOUNDS REINFORCED WITH CELLULOSE NANOFIBRILS AND A CARBON BLACK HYBRID FILLER SYSTEM
Authors: Weilert Irina , Giese Ulrich 
Published: March 2020

ABSTRACT
Cellulose is found in the walls of plant cells, making it the most common biopolymer in the world. It is mechanically stable, resistant to hydrolysis, and boasts—especially in its nanoscopic state—a large reactive surface area and low density. To realize reinforcement in rubbers, the large and polar cellulose surface must interact with the nonpolar elastomer matrix. The dispersion of hydrophilic fillers is, however, still a major challenge in rubber technology. In this work, commercially available nanofibrillated cellulose (NFC) was incorporated into a nonpolar BIIR via latex mixing. Transmission electron microscopy, tensile testing, swelling, and rheometry were used to characterize the compound properties and the reinforcing potential of NFC. The compounds were compared with the established and highly dispersible standard carbon black N550 with a medium specific surface area. In addition, hybrid filler systems with both particle types were prepared. This yielded well-dispersed nanocomposites of a new kind exhibiting high stiffness, good tensile properties, and reduced material weight.
Dinâmica socioespacial das “cidades do agronegócio” em Goiás - um estudo de caso de São João D’Aliança

Published: March 2020

O presente artigo visa explorar o fenômeno da espacialização da sojicultura no município de São João d'Aliança. Ligado às regiões metropolitanas de Goiânia e Brasília pela BR010 e a pouco mais de 400Km da região do extremo-oeste baiano, é a “porta” para o Parque Nacional da Chapada dos Veadeiros, a partir de onde entra-se em uma região com pouca aptidão natural para a sojicultura em escala. No entanto, a sojicultura no município se sobressai na microrregião. Reverberam notórios discursos públicos de apologia das ambições do setor diante de conflitos de interesse, sobretudo em choque com a política de conservação. Através de uma pesquisa predominantemente descritiva, mas também com ênfase exploratória, inquiriu-se sobre a possibilidade de inferir se a atividade desencadeia uma dinamização econômica do município e se a magnitude de seu impacto produtivo no espaço mostra-se capaz de sustentar a economia municipal. Constatou uma discrepância em termos de área produtiva e produção bruta com a produtividade da cultura, comparativamente deficitária. Os índices socioeconômicos não permitem corroborar reivindicações de que a sojicultura promove dinamização socioeconômica. Os resultados levantam o debate sobre outros perfis de políticas públicas compatibilizando-se com a resiliência ecológica no território geográfico, contemplando um quadro mais democraticamente representativo de seguimentos sociais da população.
Avaliação dos impactos ambientais gerados na implantação das pequenas centrais hidrelétricas Canhadão e Tigre no Sudoeste do Paraná, pelo método RIAM
Authors: Tomazoni Julio Caetano , Andretta Karen Merediana Rodrigues de Conto 
Published: March 2020

O impacto ambiental está relacionado à alteração realizada no meio ambiente, seja ela negativa ou positiva, portanto, ao estudá-los avalia-se as consequências de ações, para que possa ser preservada a qualidade do ambiente em todas as fases de desenvolvimento do empreendimento. O presente artigo tem como objetivo analisar os impactos ambientais ocasionados pela implantação das Pequenas Centrais Hidrelétricas (PCHs) Canhadão e Tigre através do método da matriz de avaliação de impacto rápido - RIAM. Para realizar tal análise, tendo o intuito de tornar o processo o menos subjetivo possível, procurou-se o auxílio de geotecnologias, levantamento de campo e documentos relacionados com as PCHs. Os resultados dessas matrizes permitiram identificar que os impactos negativos significativos foram: a alteração da vazão a jusante em função do período de enchimento do reservatório e / ou desvio permanente do rio, a inundação da vegetação com perda do patrimônio vegetal, o desmatamento do canteiro de obras, locais que são prejudiciais à produção florestal, assoreamento do reservatório, processos de erosão, degradação das áreas utilizadas para a exploração de material de construção e obras de construção temporárias. Os impactos positivos significativos foram: a melhoria da rede rodoviária local e, no contexto atual, as PCHs, são apresentadas como uma das formas mais sustentáveis de produzir energia elétrica, utilizando o potencial hidráulico da região estudada.
Carlos Astrada frente a la tercera visita de Ortega a la Argentina
Authors: Prestía Martín 
Published: March 2020

El presente trabajo tiene como propósito poner de relieve un aspecto de la tercera visita de Ortega a la Argentina aún desconocido por la crítica: la recepción de las lecciones que el español dictara en Amigos del Arte por parte de Carlos Astrada (1894-1970), quien fuera uno de los mayores filósofos argentinos del siglo XX. La recensión de las lecciones por parte de Astrada apareció en el diario nacionalista El Pampero bajo el título “El Centauro y los Centauristas. La originalidad del señor Ortega y Gasset” el 23 de noviembre de 1939, que hemos encontrado en el curso de nuestras investigaciones y que presentamos a continuación. La misma siguió el tono general de «marginación» con el que Ortega fue recibido por el ambiente intelectual y académico argentino. Esta recepción es parte de una compleja relación filosófica de Astrada con Ortega, que en el presente trabajo sólo podemos apuntar brevemente.
This paper aims to highlight an aspect of Ortega y Gasset's third visit to Argentina, still unknown by critics: the reception of the lessons he dictated in Amigos del Arte by Carlos Astrada (1894-1970), one of the most important Argentine philosophers of the twentieth century, the main introducer of Martin Heidegger's philosophy to Argentina. The review of the lessons appeared in an article published in the nationalist newspaper El Pampero under the title “El Centauro y los Centauristas. La originalidad del señor Ortega y Gasset” on November 23, 1939, which I have found in the course of my investigations. It shares the general tone of “marginalization” with which Ortega was received by the Argentine intellectual and academic environment. Likewise, this reception is one of the instances of a complex philosophical relationship between Astrada and Ortega, which in the present work I can only aspire to briefly point out.
¿Perdidos en el laberinto? Husserl, Ortega y Gaos ante los desafíos de la diversidad cultural
Authors: Díaz Álvarez Jesús 
Published: March 2020

Este artículo trata de mostrar la forma en que tres destacados filósofos del siglo XX ––Edmund Husserl, José Ortega y Gasset y José Gaos–– han lidiado con la diversidad cultural. Ligados entre sí por fuertes vínculos intelectuales, los protagonistas del texto plantean tres modos diferentes de acercarse a este crucial y espinoso asunto en donde el papel asignado a la razón resulta de especial relevancia. Husserl confiará plenamente en ella. Ortega, incluso el Ortega más husserliano, abajará considerablemente tales pretensiones. Y Gaos, radicalizando las tesis perspectivistas de su maestro, considerará que es mejor asumir su impotencia. El juego de espejos que el ensayo pretende crear con el cruce de las tres propuestas quiere poner en valor la pertinencia de la filosofía hecha en español en los debates más acuciantes del presente.
This article tries to show how three leading philosophers of the twentieth century ––Edmund Husserl, José Ortega y Gasset and José Gaos–– have addressed the issue of cultural diversity. Linked to each other by strong intellectual relations, the protagonists of the text will offer three different ways of approaching this crucial and thorny issue where the role assigned to reason is of special relevance. Husserl will fully trust her. Ortega, even the most Husserlian one, will lower such claims considerably. And Gaos, radicalizing the perspectivist theses of his teacher, will consider that it is better to assume her impotence. The game of mirrors that the essay tries to recreate with the crossing of the three proposals wants to value the relevance of the philosophy made in Spanish in the most pressing debates of the present.
José Ortega y Gasset y María Zambrano, una relación intelectual bidireccional
Authors: Caballero Beatriz 
Published: March 2020

Es bien sabida la influencia que José Ortega y Gasset ejerció en María Zambrano, quien siempre se consideró su discípula, pese a que los senderos de su pensamiento pronto divergieron de la ruta trazada por el maestro. El propósito de este artículo es arrojar luz sobre el intento de Zambrano de influenciar las ideas y actuación política de Ortega –lo cual ocurrió particularmente entre los años 1930-36–, así como también explorar la naturaleza y alcance de esta influencia prestando especial atención a la correspondencia entre ambos.
Ortega’s influence on Zambrano is well-known. She always considered herself as her disciple, despite the fact that her thought diverged from the path of her maestro. The purpose of this article is to shed light on Zambrano’s effort to influence Ortega’s ideas and political action between the years 1930-36, as well as exploring the nature and breadth of these influence paying particular attention to their correspondence.
