Una compilazione altomedievale: il Non omnes quidem e i Gynaecia di Mustione
No full textGynaecia by Mustio, a successful Latin re-elaboration of Gynaecia by Soranus, are preserved in eighteen manuscripts, two translations and three epitomes. The first epitome, known as Non omnes quidem, descends from a manuscript of the branch of the ms. Laur. plut. 73.1, but is earlier than that and occasionally provides improvements to Gynaecia by Mustio. This text is altered by the epitomizer through omissions, mergings and interpolations, including twenty-one additamenta, mostly from the fourth book of Ad Eunapium by Oribasius and the fifth and sixth books from a gynaecologic compilation transmitted in ms. Laur. plut. 73.1. This article deals with the relation between the manuscript tradition of the Gynaecia and that of its abridgement Non omnes quidem and the working methods of the compiler
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
Impact of heat treatments on technological performance of re-milled semolina dough and bread
No full textRe-milled semolina used for bread making is appreciated from consumers for its typical sensory features and nutritional attributes. Fluid bed drying treatment can be applied to semolina to change its bacteriological properties, to prolong shelf life by decreasing the risk of mould development, and to degrade some mycotoxins. The main goal of the present work was to evaluate the impact of heat treatment on structural development of semolina dough during mixing and leavening and on bread characteristics. Semolina was treated with fluidized bed drying at 90°C, 120°C, or 150°C for 5, 15 or 30 min. The heat treatment affected colour, moisture content, and farinograph indices of semolina. Results showed that the use of heat treated re-milled semolina significantly (P <0.05) affected the dough leavening kinetics and bread parameters such as crumb structure and mechanical parameters, in particular for treatment at 150°C for 30 min. On the contrary, after treatment of semolina at 120°C for 30 min, an improvement in the leavening phase of dough and no significant effects on bread quality were observed. Therefore, moderate heat treatment can be applied to semolina without having any negative impact

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
Overexpression of pectin methylesterase inhibitors in Arabidopsis affects defence against pathogens
No full textHow do pectin methylesterases and their inhibitors affect the spreading of tobamovirus?
No full textAfter replication in the cytoplasm, viruses spread from the infected cell into the neighboring cells through plasmodesmata, membranous channels embedded by the cell wall. As obligate parasites, viruses have acquired the ability to utilize host factors that unwillingly cooperate for the viral infection process. For example, the viral movement proteins (MP) interacts with the host pectin methylesterase (PME) and both proteins cooperate to sustain the viral spread. However, how and where PMEs interact with MPs and how the PME/MP complexes favor the viral translocation is not well understood. Recently, we demonstrated that the overexpression of PME inhibitors (PMEIs) in tobacco and Arabidopsis plants limits the movement of Tobacco mosaic virus and Turnip vein clearing virus and reduces plant susceptibility to these viruses. Here we discuss how overexpression of PMEI may reduce tobamovirus spreading
