Increased porosity turns desorption to adsorption for gas bubbles near water-SiO2 interface
No full textWe consider theoretically the retarded van der Waals interaction of a small gas bubble in water with a porous
SiO 2 surface. We predict a possible transition from repulsion to attraction as the surface is made more porous.
It highlights that bubbles will interact differently with surface regions with different porosity (i.e., with different
optical properties)
Variations on the Author
No full text“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
About One Type of Jewelry of the Head of the Slavs: on the Materials of Malyi Rzhavets and Martynivka Treasures
No full textУ статті дається інтерпретація великих так званих «бобоподібних» пластин, із складу Малоржавецького та Мартинівського скарбів та визначається їх призначення як прикрас головного убору.The article analyses «bobo-similar» plates jewelry
from Malyi Rzhavets and Martynivka — four specimens.
In 1889 near the village Malyi Rzhavets was
found a small treasure of women’s jewelry. In 1907, in
the village Martynivka was found another treasure that
included the women’s and men’s jewelry and Byzantine
wares. Both complexes belong to the treasure of «Martynivka
» type or the first chronological hoard-group by
O. A. Shcheglova. One can assume the interpretation of these products as large temple ornament or decoration
of scythe. Quite similar (though not entirely similar) bronze ware — lamellar temporal rings — are known
in the antiquities of Roman times in Central Lithuania. The chronology of these jewelry — the phase B2 or
B2 / C1 — 100—230 А D. Finds from Central Lithuania and treasures from Malyi Rzhavets and Martynivka
differ in some design features, ornamental motifs and sizes. This can explain the chronological difference
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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

Adjusting Properties of Electrode Pitch with Fractions of Coal Tar
No full textA. Starovoyt: ORCID 0000-0001-7280-6538; E. Malyi: ORCID 0000-0001-7280-6538ENG: The paper presents the investigation results of the organic mass modification of the impregnating pitch of coal tar with low pyrolysis degree. The processes that form the pitch operational properties in the impregnation technology of graphitized electrodes were studied. Specific features of the modifying additive effect on the quality characteristics of the pitch and its group composition were established. Such technological approach makes it possible to intensify the impregnation process of blanks for graphitized electrodes

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
