The dielectric constant and molecular weight of bromine vapor
Get PDFIt is shown that the conclusion reached by Bramley in a recent article that bromine has the formula (Br2)6 is inconsistent with previous results relating to the density of this substance in the gaseous state and that it is not theoretically justified by the considerations presented by the author
[Letter] 1957 December 19, Pasadena [to] Jacob Zeitlin, Los Angeles, CA / Linus Pauling.
No full textThe letter is typed on California Institute of Technology letterhead, from the chemistry lab of Gates and Crellin.Pauling says it was a pleasure to talk with Zeitlin the other evening and thanks him for sending a first edition of Pauling\u27s book for his examination. After examining the annotations, Pauling affirms that while he did not find anything new to him (many of the remarks in the marginalia having been addressed in the second edition), "I was pleased to see what one reader had done." Pauling may be referencing his 1939 book _The nature of the chemical bond and the structure of molecules and crystals; an introduction to modern structural chemistry_ . In addition to winning the Nobel Peace Prize for his work on the role of science in a free society and his anti-nuclear proliferation stance, Pauling also published texts on line spectra, quantum mechanics, the nature of the chemical bond, and the use of Vitamin C to combat cancer
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
