(chlorothienyl)[(dihydrooxazolyl)phenoxy]butanone or [(carboxyphenoxy)oxopentyl]methyl-1H-pyrrolecarboxaldehyde and analogs, methods for their preparation and their use for the inhibition of rhinovirus infections
No full textCompds. for the treatment of rhinovirus infections are claimed.; such compds. are e.g. 1-(2-chloro-5-thienyl)-4-[4-(4,5-dihydro-2-oxazolyl)phenoxy]-1-butanone (I) or 4-[5-[4-(carboxyphenoxy)]-1-oxopentyl]-1-methyl-1H-pyrrole-2-carboxaldehyde (II). Condensation of 2-chloro-5-(5-chloropentanoyl)thiophene with 2-(4-hydroxyphenyl)-4,5-dihydrooxazole gave I (97% yield). I inhibited HRV-14 selectively. [on SciFinder(R)
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
Preparation of 6-benzyl-4-oxopyrimidines as antiviral agents
No full textSubstituted 6-benzyl-4-oxopyrimidines having formula (I) are described, wherein: X is selected from the group consisting of O and S; R is selected from the group consisting of C1-4 alkyl and C5-6 cycloalkyl; R', R" and Z, equal or different among them mean H or C1-4 alkyl considering that, when X = O, R and R' cannot be both equal to H; their pharmaceutically acceptable salts and their soluble derivatives; one of their preparation processes and their use for the preparation of pharmaceutical compositions useful for the treatment of viral infections
