La rottura del legamento crociato craniale nel cane. Recenti aspetti eziopatogenetici e terapeutici
Special Issue Physiological and Molecular Responses of Plants to Engineered Nanomaterials
: Engineered nanomaterials (ENMs), by definition materials with a size between 1 and 100 nm, are becoming an important part of the economy and thanks to their many fields of applications, from photovoltaic cells to fertilizers, are increasingly coming into contact with plants and with the environment in general [...]
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
L’ECOGRAFIA QUALE AUSILIO DIAGNOSTICO IN CORSO DI PATOLOGIE DELLA MAMMELLA DELLA BOVINA DA LATTE
Twenty-five dairy cows were subjected to clinical investigation followed by clinical examination and ultrasonography of mammary glands. Secretions and tissue samples taken from each animal were subjected to histological and microbiological examinations. After clinical evaluation, animals were slaughtered and mammary parenchyma macroscopically evaluated. According to our results, ultrasonography in the diagnosis of mastitis does not involve a significant advance for practical applications compared to laboratory investigations so far applied. However, it allows a corrected characterization of the lesion by directing the clinician in selecting therapeutic and prognostic evaluation
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
Sviluppo di viti ad altissima resistenza per applicazione su motori endotermici altamente performanti e settore aerospace
Stato dell’arte sull’effetto delle variabili geometriche (raccordi sottotesta, forma filetto, giochi, ...) e delle condizioni di installazione (precarico, rigidezza delle parti serrate, presenza di sistemi antisvitamento, numero di filetti in presa ...) sulla resistenza a fatica a temperatura ambiente. Individuazione di geometrie e forme, compatibili con la funzionalità delle viti, in grado di aumentare la resistenza a fatica;
