Verificación del cumplimiento de la normativa vigente de seguridad contra incendios en planta de GLP VARIGAS de la provincia de Salta
Full text linkEn el presente trabajo de investigación se analizará la aplicación e implementación de la normativa vigente vinculada estrictamente a las condiciones de higiene y seguridad contra incendio en la planta de GLP (Gas Licuado de Petróleo) “VARIGAS” de la provincia de Salta. Para la realización de la misma se toma como base una práctica y los sustentos teóricos – legales que la enmarcan, al igual que los procesos metodológicos pertinentes.Fil: Arce, Andrés Maximiliano.

Optimización de mangas de ganado vacuno conforme a las buenas prácticas de higiene y seguridad
Full text linkEn la siguiente tesina, se desarrolla un trabajo de investigación, basado en los métodos de trabajo aplicados en “la manga” con animales vacunos, con los principales riesgos derivados del mismo. Se toma en cuenta antecedentes de accidentes, encuestas a trabajadores rurales, visitas y observaciones al establecimiento, para así proponer cambios tanto en las instalaciones como en algunos métodos de trabajo, con el objetivo de crear un ambiente de trabajo seguro y eficaz.Fil: Fraunhofer Delaloye, Gonzálo.

Imaging resin-cast osteocyte Lacuno-Canalicular system at bone-bioactive glass interface by scanning electron microscopy
Full text linkThe morphology of the osteocyte lacuno-canalicular system at the bone-biomaterial implantinterface has not been fully investigated. In this study, the resin-cast scanning electron microscopy technique was used, for the first time, to image the lacuno-canalicular network within neoformed bone around bioactive glass ~BG! particles implanted in rat tibia bone marrow. The most salient finding was that the osteocyte canaliculi pass through the calcium-phosphorus layer formed at the bone-BG interface and reach the silica-rich layer of the reacted BG.Fil: Gorustovich Alonso, Alejandro Adrian.

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
A histologic study of bone response to bioactive glass particles used before implant placement: A clinical report
Full text linkThis clinical report describes the microscopic analysis of the postextraction bone response to bioactive glass particles used prior to titanium implant placement, after a healing period of 6 months. The clinical and radiographic follow-up were performed over a 3-year period after implantation.Fil: Stvrtecky, Roberto.

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
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
