Studio preliminare per l'analisi delle resitenze su fondo a dune in condizioni di moto vario
No full textPhenomena of the response of dune resistance of cohesiveless granular bed to unsteady flow are experimentally studied. For the purpose of the investigation a laboratory flume is employed and a particular selection of experimental methods is carried out, permanent flow conditions check is carried in comparison with known theories. Eventually first unsteady flow results are discussed together with some data from the literature
Sediment transport and morphodynamics of the Tanaro River, northwestern Italy.
No full textThis paper describes a study to determine sediment transport processes and morphodynamics of the Tanaro River in North-western Italy to support river management strategies. An integrated hydraulic-geomorphological approach was used to 1) assess geology, land use and climate controls affecting sediment yield at the catchment scale 2) evaluate changes in channel morphology and sediment transport processes and 3) model river channel change. Numerical simulations were used to evaluate the transient solution for flow and bed profile due to the propagation of flood wave. It is concluded that Alessandria town is the most critical reach from the flooding point of view and so different design solutions were tested in order to verify whether geometric alteration of the river bed allow for an increase in flood capacity
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
