    To develop, assemble and test a prototype of a novel production plant, suitable to produce microparticles (MPs) processing highly viscous feed solutions (FSs). The novel prototype of production plant is suitable to process large amounts (2 L or more) of FSs, characterized by a high viscosity, to produce MPs

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

    Variations on the Author

    “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

    Caratteristiche reologiche di impasti e pane ottenuti con aggiunta di zenzero (Zingiber officinale Roscoe)

    In questo lavoro sono stati determinati alcuni parametri reologici di impasti da pane e relativi prodotti finiti utilizzando rispettivamente misure fondamentali (test di Frequency Sweep) ed empiriche (Texture Profile Analysis). I campioni sono stati preparati utilizzando i tradizionali ingredienti del pane (farina di grano tenero, acqua, sale, lievito) con l’aggiunta di zenzero (Zingiber officinale Roscoe) in polvere in diverse percentuali (0, 3, 4, 5 e 6%), e panificando con metodo biga. L’aggiunta di un ingrediente come lo zenzero alla formulazione del pane si inserisce nell’ attuale tendenza che intende aumentare o comunque migliorare le caratteristiche nutrizionali dei prodotti alimentari, tra i quali anche i prodotti da forno, attraverso l’aggiunta di ingredienti che forniscano “funzionalità” ai prodotti finiti. La quantità di zenzero da utilizzare in formulazione deve essere tale da consentire l’ottenimento di un prodotto ricco in sostanze con potere antiossidante evitando però di modificare negativamente le caratteristiche reologiche dell’impasto e le peculiari proprietà fisiche e sensoriali del prodotto finito. Tra i campioni studiati, sia di impasto che di pane, quelli con il 4,5% di zenzero hanno mostrato le migliori caratteristiche reologiche e sono risultati nel complesso accettabili dal punto di vista sensoriale
