Tensiometer, 1922
No full textInventor: Pierre Lecomte du Noüy
How it began: The laboratory wanted to study surface tensions of various blood properties in order to understand wound healing. Methods then in use measured surface tension by calculating weight of hanging drops, a process that was time-consuming and made two readings necessary.
What it does: This instrument measures tension based on adherence to a platinum ring that is submersed in a liquid and slowly withdrawn. The tension on the wire counteracts the tension of the liquid and finally breaks it. As the ring is pulled out of the liquid into the air, the tension that is required can be precisely measured.
Impact on medical science: Because of its rapidity, simplicity and reliability, the instrument was widely adopted and is still used to measure surface tension of liquids.

Lecomte du Noüy, Pierre
No full textPierre Lecomte du Noüy, circa late 1930s
Pierre Lecomte du Noüy (1883, Paris – 1947) was a French biophysicist and philosopher. He is best remembered by scientists for his work on the surface tension, and other properties, of liquids. He was an associate member of the Rockefeller Institute working in Alexis Carrel\u27s lab from 1920 through 1928, Head of the biophysics division of the Pasteur Institute, and the author of some 200 published papers. He invented the Tensiometer, a scientific apparatus that used his du Noüy ring method to measure the surface tension of liquids.

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
