Assetto endocrino-metabolico in cagne affette da pseudogravidanza
No full textUna condizione particolare del ciclo riproduttivo della cagna è la pseudogravidanza. Tale condizione comporta anomali a livello dell'utero e della ghiandola mammaria simili alla gestazione. Scopo della ricerca è stato la valutazione di alcuni profili ormonali caratteristici ed anche parametri ematochimici. I risultati delle indagini eseguite hanno permesso di affermare che tale condizione di peseudogravidanza richiede sicuramente un approccio più approfondito nell'analisi delle fasi endocrino-metaboliche legate al fenomeno. Si richiede, quindi, l'analisi di sostanze peptidiche e ad azione neurotrasmettitrice e neuroendocrina coinvolte in tali meccanismi
Catalytic oxidation of soot from diesel exhaust gases. 1. Screening of metal oxide catalysts by TG-DTG-DTA analyses.
No full textThermal anal. was employed as a screening technique to evaluate the activity of catalysts for the oxidn. of soot produced during combustion. Oxidn. took place over metal oxide-based catalysts at temps. much lower than in the absence of catalyst. The best results were displayed by a Cu/V/K-supported catalyst that is very active at .apprx.330. In the absence of O, 16% of the soot was oxidized by the O of the catalyst, suggesting that a redox mechanism is involved
Correlazioni tra prolattina, cortisolo, T3, e T4 nella cagna in corso di presudogravidanza
No full textThe levels of prolactin, cortisol, T3 and T4 have been measured in 9 bitches during pseudopregnancy. The analysis of the data showed that thyroid hormones significantly decreased during the lactation period while cortisol and prolactin had an opposite trend. Furthermore, the patterns of thyroid hormones were inversely related both to cortisol and prolactin. The authors suggest that metabolism of thyroid hormones is involved in generating lactation during pseudopregnancy

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
