CIL:10052
No full textThis group of micrographs illustrate the ultrastructural characteristics of the middle layer of the three meningeal layers that cover the central nervous system The arachnoid cells contain abundant intermediate filaments that occupy a substantial volume of the cytoplasm. In some cells the intermediate filaments are organized into numerous coils of relatively uniform size and lie parallel to the outer surface of the central nervous system, such that sections cut tangential to the membrane surface (see CIL:9301) show the spirals but transverse sections such as this one do not. The plasma membrane of these cells has many caveolae. Adjacent arachnoid cells are connected by large desmosomes. Images were recorded using a Philips EM301 TEM at 80 kv. Original glass plates were scanned and digitized using an Epson V750 flatbed scanner with a step size of 15 micrometers. This group of images complement those published in the reference below.

No full text Recently rediscovered text copies of what is now P. BM EA 10052, 6.22–23 by Anthony Harris from his Notebook 5, in conjunction with surviving unpublished fragments from this section of the papyrus, identify a Queen Tyti as a King's Wife of Ramesses III, helping to resolve a long-standing conundrum in the study of the Twentieth Dynasty royal family. </jats:p
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
CHARACTERIZATION OF THE ABILITY OF BRITTLE MATERIALS TO FRACTURE AND DUST FORMATION BY NANOINDENTATION
Get PDFApplication of nanoindentation as a method for determing the ability of fine dust formation in brittle materials is being discussed. Using the original nanoindentation technique in single and cyclic modes the correlation between elastic modulus and dust formation ability has been established.Работа выполнена при поддержке Российского научного фонда (грант № 18-77-10052)
