ElectroSpray Immobilization of LAccase foR cANnabinoids deTEction - ESILARANTE (PRIN 2022)
No full textThe main idea at the base of ESILARANTE project is to characterize and develop a portable sensor platform for tetrahydrocannabinol (THC) detection based on laccase biosensors produced through the green, low-cost and environment-friendly ElectroSpray Deposition (ESD) technique. The commercialization of such a platform will push the use of biosensors for forensic analysis and on-road detection beyond the current state of the art. The development of selective, ecofriendly, low cost, stable and recycling biosensors in different environments such as atmosphere, food industry or in clinical analyses is strongly required. Among the most studied bio-components, the enzymes play a leading role, being a class of selective and sensitive biological recognition elements. Thus the fabrication of enzyme biosensors based on laccase has attracted a huge interest in the last years since this, robust and cheap enzyme, is used in several fields. In the fabrication process, enzyme immobilization strategy is a key factor to develop an efficient tool with appropriate performances. Recently the PI has manufactured new promising amperometric laccase-based biosensors with unprecedented reuse and storage capabilities using
the ambient ESD methodology as immobilization technique. The biosensors have been electrochemically tested to prove that such an immobilization technique is suited to manufacture high performance devices. Thanks to an interdisciplinary effort the first goal is to achieve an understanding at the molecular level of these new promising biosensors, their stability and reuse by using different spectroscopies, microscopies and analytical techniques. This would allow to make a step forward in the development of new green and renewable systems to reduce pollution, which is at the core of some pillars of the Horizon Europe program and of strong relevance in the NextGenerationEU agenda. The second goal is to apply laccase-based biosensors for the development of a portable and cost-effective platform for the detection of cannabinoids in capillary blood samples. While cannabinoid sensing protocols are well established in lab techniques, miniaturized and portable sensors are still not well developed. Electrochemical devices promise to reduce greatly the analysis time per sample and to lower dramatically the costs while allowing sensitivity and miniaturization. To face the challenges set by these ambitious goals, a consortium has been set up consisting of two units, CNR and UNIBO. The manufacture of the biosensors together with the electrochemical and physico-chemical characterization will be done at the CNR. These activities will be complemented at UNIBO through established mass-spectrometric methodologies, for a complete analytical validation of the THC biosensor and to characterise the laccase solution used for the ESD, which will help us to disentangle the reasons behind such an optimal immobilization

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

Notice that in A and C, the posterodorsal area is vertical and followed by the forked neural crest, whereas in B and D the posterodorsal area is roof-shaped, and the neural crest terminates in the middle of the incisura dorsalis. In contrast, the medial edges of the prezygapophyses (dashed lines in A, C) are a less variable character (divergent in the case of Ichthyosaura and parallel in Lissotriton; see diagnoses section).

In the original article, the author names appear as the following: Gallone Maria Serena, Gallone Maria Filomena, Larocca Angela Maria Vittoria, Germinario Cinzia and Tafuri Silvio. However, this is incorrect, and the author names should appear as per the below: Maria Serena Gallone, Maria Filomena Gallone, Angela Maria Vittoria Larocca, Cinzia Germinario, Silvio Tafuri.

No full textImagens 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
