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
Electrochemical Studies on Eriochrome Violet B and Its Lanthanide Complexes. II. Controlled-potential Coulometric Studies
No full textControlled-potential coulometric studies
of Eriochrome Violet B (5-sulpho-2-hydroxy-benzeneazo-2-naphthol) using a
stirred mercury pool cathode have shown that four electrons per molecule of dye
are required for the reduction and that the amines are the final reduction
products both in acidic and basic media. The lanthanide-dye complexes are
reduced in a similar manner to the free dye.
The reduction of Eriochrome Violet B does
not obey first-order kinetics, and the observed reaction rate may be related
qualitatively to a disproportionation mechanism involving an unstable hydrazo
compound. The coulometric and polarographic behaviour of Eriochrome Violet B
has been compared with that of the uranium system, which is well known to
involve a disproportionation step.

Adsorption of violet B by agricultural waste of soft pistachio shells
No full textIn this study, inexpensive agricultural waste pistachio sells was used for adsorption of violet B. Fourier transform infrared spectroscopy (FTIR) and scanning electron microscope (SEM) were used to characterize the pistachio shells. The morphology of pistachio shell was studied by SEM and it showed the porous structure of pistachio shells. Different parameters like contact time, pH and mass of sorbent were investigated. The adsorption is dependent on pH of the medium where the removal efficiency increases as the pH turns to 11. The contact time studies showed that 45 min shaking time was sufficient to achieve the equilibrium. The reaction kinetics data were analyzed using two reactions kinetic of pseudo-first-order reaction model and pseudo-second-order reaction model, and it was found that the removal of violet B followed the pseudo-second order reaction model.Keywords: Adsorption, violet B, agricultural waste, pistachio shell.

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
