No full textSelenio in uova biofortificate: confronto con uova commerciali
No full textObiettivi. Il selenio, micronutriente essenziale per l’uomo, sembra svolgere un ruolo protettivo nei confronti dell’insorgenza di malattie cronico-degenerative, in particolare del cancro, grazie alla sua attività antiossidante. La sorgente naturale di selenio è rappresentata dalla dieta e la sua concentrazione nei cibi dipende dalle caratteristiche geobotaniche dell’area di provenienza degli alimenti. Nell’ambito di uno studio sull’arricchimento delle uova con acidi grassi w3 e microelementi essenziali (Se e I), il nostro obiettivo era quello di verificare se la supplementazione con Se potesse realmente arricchire l’uovo con questo elemento contribuendo ad un miglioramento della qualità nutrizionale dell’uovo. Per confronto sono state esaminate uova presenti normalmente sul mercato.
Metodi. La prova è stata condotta su sette gruppi di galline ovaiole, alimentate con un mangime di base solo o addizionato con I o Se o con entrambi i sali. Le uova commerciali sono state acquistate tenendo conto dei diversi sistemi di allevamento delle ovaiole.
Risultati. Il Se si accumula prevalentemente nel tuorlo delle uova sia commerciali (1,04±0,28 mg/g) che trattate (da 1,60±0,21 a 1,98±0,16 mg/g, secondo il trattamento). La supplementazione con Se e ancora di più quella con Se + I si associava ad una riduzione del contenuto di Cd , in misura inferiore di Pb, e favoriva l’accumulo di acidi grassi w3. Tuttavia si è osservato una tendenza al calo di Zn nei prodotti supplementati

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
