Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Emulsion-based synthesis and characterization of biphasic Janus particles for dual drug delivery
No full textJanus particles exhibit many unique chemical, optical, electrical, and physical properties due to their two chemically distinct surfaces. They are highly sought after for diverse applications across many fields including electronics, energy, catalysis, and emulsion stabilization. Janus particles also hold great promise in the field of biomedical engineering as drug delivery vehicles, theranostic platforms, and components of biosensors. As drug delivery vehicles, they offer a platform for co-encapsulating drugs with widely disparate solubility as well as independent release kinetics. However, large-scale synthesis methods are needed before Janus particles can realize their full potential in biomedicine. A novel technique based on the phase separation of two immiscible polymers and/or lipids within single O/W and double W/O/W emulsion droplets is presented for the production of Janus particles. The effects of various formulation and process variables on final Janus particle properties including particle size, stability, morphology, and encapsulation efficiency are studied. A wide range of Janus particle morphologies were synthesized, including acorn-like, spherical, crescent moon, and two nearly separated droplets. From a purely thermodynamic perspective, particle shape is a function of the interfacial tensions between the two polymers, as well as the interfacial tensions between each of the polymers and the aqueous phase containing surfactant. These interfacial tensions are adjusted by changing the type and concentration of surfactant in the water phase, making a wide range of morphologies accessible. In order to quantifiably describe the influence of interfacial tension on particle morphology, a thermodynamic model for the prediction of Janus particle morphology was developed. The model is derived from first-principles, in which the exact shape of a Janus particle is extracted via total free energy minimization of Janus particles modeled as two overlapping semicircles. In reverse, particle geometry measurements obtained from microscopy can be applied to the model in order to explicitly calculate the volume ratio and the surface tension of each of the three interfaces. The ability to control Janus particle shape is of fundamental importance for many potential applications, as function depends on structure. Janus particles were applied to a case study involving the treatment of lung cancer with doxorubicin, a broad spectrum chemotherapeutic, and curcumin, a bioflavanoid with antioxidant, anti-inflammatory, and antitumor effects. The Janus particles containing doxorubicin and curcumin completely inhibited tumor growth over a four-week treatment period, attesting to the advantages of bicompartmental Janus carriers for dual drug delivery of synergistic compounds.Ph.D.Includes bibliographical referencesby Jennifer Sherri Winkle

Imagens de Otto Maria Carpeaux: esboço de biografia
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Filosofia e Ciências Humanas, Programa de Pós-Graduação em História, Florianópolis, 2015.Este esboço de biografia procura citar algumas imagens de Otto Maria Carpeaux: construções biográficas de naturezas múltiplas, elaboradas em contextos, por atores e sob condições igualmente díspares. Está constituído a partir de uma visão crítica da História, o que permite que ?outras imagens?, fragmentárias e não monumentais, também tenham espaço. Em diálogo com o princípio da montagem, este esboço apresenta-se em duas partes. Na primeira, Imagens possíveis, estão citadas as imagens elaboradas em vida e post mortem acerca do austríaco-brasileiro que nasceu em Viena em 1900, se exilou no Brasil em 1939 e morreu no Rio de Janeiro, em 1978. Na segunda, Montagens possíveis, apresentam-se duas possibilidades de exercício biográfico: pela leitura alegórica do documentário O velho e o Novo (Otto Maria Carpeaux), entendido como instrumento de intervenção no contexto ditatorial brasileiro e de uma reelaboração biográfica concernentes às suas experiências europeias; e pelo Caderno de imagens críticas, registro dos encontros em Carpeaux pelo meio de imagens críticas produzidas a partir da cesura do presente.Abstract : This biographical sketch attempts to quote some images of Otto Maria Carpeaux: various types of biographical constructions, carried out in different contexts by disparate authors under conditions just as distinct. It stems from a critical view of history, allowing for ?other images? fragmented and non-monumental ? to share the space.In dialogue with the montage principle, this sketch has two parts. The first, Possible Images, quotes the images produced during and after the life of the Austrian-Brazilian, who was born in Vienna in 1900, went to Brazil in exile in 1939 and died in Rio de Janeiro in 1978. The second part, Possible Montages, presents two possibilities of a biographical exercise: through the allegorical reading of documentary O Velho e o Novo (Otto Maria Carpeaux), understood as an instrument of intervention in the Brazilian dictatorship context and as a biographical retelling of the author?s European experiences; and through my Scrapbook of Critical Images, a record of the encounters in Carpeaux through critical images produced from the caesura of the present
The Janus faced teacher educator
No full textThis paper focuses on the Janus face-teacher educator and researcher. Drawing on existing international literature, our aim is to position ourselves in the discussion relating to our own and other research. In this paper we limit ourselves to discuss two main components, namely teaching and research in relation to which teacher educators seem to experience a rather strong tension. We maintain that the quality of teaching does not become inferior to research and publishing in teacher education. This necessitates that sufficient resources are provided for assuring the quality of teaching and for research; subsequently the two activities are complementary and not contradictory to each other. Our claim is that teacher educators in most settings are Janus-faced due to the competing demands of excellence in both research and teaching. However, we strongly believe that the two main responsibilities of teacher educators which form the Janus face, can melt into each other in the face of a researching teacher educator.Portuguese national funds through the FCT (Foundation for Science and Technology) within the framework of the CIEC (Research Center for Child Studies of the University of Minho) project under the reference UID/CED/00317/201
Werkstofftrends: Janus-Partikel
No full text3Janus, der römische Gott des Anfangs und des Endes, und insbesondere seine Darstellung als vorwärts- und rückwärtsblickender Janus-Kopf gelten als Symbol der Zwiespältigkeit. Eben jener Name wurde daher vor etwas mehr als 30 Jahren für Partikel und Materialien gewählt, die in klar abgegrenzten Bereichen ihrer Oberfläche verschiedene und teils gegensätzliche physikalische oder chemische Eigenschaften aufweisen – in gewisser Weise also zwiespältig sind. So kann ein Janus-Partikel auf der einen Hälfte seiner Oberfläche wasserabweisend sein und auf der anderen wasserliebend. Die Eigenschaften der Janus-Materialien können im Prinzip direkt auf eine bestimmte Anwendung hin zugeschnitten werden. Die Bandbreite ist dabei sehr groß: So können sie mit ihren spezifischen Eigenschaften potenziell für die Sensorik (z. B. Gase), die (Photo-)Katalyse (Wasserstoffherstellung), die Wärmeregulation (aktive Kühlung), die Stofftrennung (z. B. Meerwasserentsalzung), die Robotik (z. B. Mikromotoren) sowie im Bereich der Energiewerkstoffe (z. B. Piezoelektrik) und der Medizin (z. B. Drug Delivery Systeme) Verwendung finden. Im Artikel wird ein kurzer Abriss zum aktuellen Forschungsstand gegeben zukünftige Herausforderungen angeschnitten.
Maria José ao encontro de Tchekov
No full text“A Carta da Corcunda para o Serralheiro” (“Letter from the Hunchback Girl to the Metalworker”), signed by Maria José, was first performed in a theatre show in 1988 (by actress-director Maria do Céu Guerra), two years before the typescript was published in book form for the first time by Teresa Rita Lopes. The evidence upon which this article is built is that it was the theatre that revealed the dramatic destination of this singular epistle of the only female heteronym that Fernando Pessoa invented, which was also the last heteronym to be created by the author. The dramatic construction of Maria José can be approximated to the character-building strategies in Anton Chekhov’s realist dramaturgy, in a way that differs from Pessoa’s other dramaturgical experiences. The analysis of Chekhov’s ascendancy over Stanislavski’s research, as well as the importance of Schopenhauer’s conception of the tragicomic, which is simultaneously projected onto Chekhov’s theatre and Maria José’s profile, are favourable lines of reading for this rapprochement between Pessoa and the Russian fiction writer and playwright. Pessoa’s readings of Chekhov’s texts (such as the play Uncle Vania and the short story “Vanka”) provide relevant data for assessing the magnitude of this encounter.“A Carta da Corcunda para o Serralheiro”, assinada por Maria José, começou por ser difundida num espectáculo de teatro em 1988 (pela actriz-encenadora Maria do Céu Guerra) dois anos antes de o dactiloscrito se ver publicado em livro, pela primeira vez, por Teresa Rita Lopes. Parte-se da evidência de ter sido o teatro a revelar a destinação dramática da epístola singular do único heterónimo mulher que Fernando Pessoa inventou, que terá sido também o último a ser criado pelo autor. A construção dramática de Maria José pode ser aproximada às estratégias de construção de personagem na dramaturgia realista de Anton Tchekov, de um modo que se distingue de outras experiências dramatúrgicas de Pessoa. A análise do ascendente de Tchekov sobre as pesquisas de Stanislavski, bem como a importância da concepção de tragicómico em Schopenhauer, que se projecta em simultâneo sobre o teatro de Tchekov e sobre o perfil de Maria José, são linhas de leitura propícias para esta aproximação entre Pessoa e o ficcionista e dramaturgo russo. As leituras de textos de Tchekov por parte de Pessoa (como o caso da peça Tio Vânia e o conto “Vanka”) fornecem dados relevantes para avaliar a magnitude deste encontro
