Some factors influencing the determination of eutectoid transformation start and finish temperatures in hypoeutectoid steels
No full textTyt. z nagłówka.Bibliografia s.127-[128].Dostępny również w formie drukowanej.ABSTRACT: This paper presents problems related to the proper determination of the eutectoid transformation start and finish temperatures in steels during heating. Information from references indicate an essential influence of interlamellar spacing in pearlite on the formation of the dilatation effect related to the eutectoid transformation finish, on dilatometric curves. It was revealed, in this paper, that the appearance of the dilatation effect related to the eutectoid transformation finish in hypoeutectoid steels or its lack in the heating dilatograms depends on the resolution ability of the applied dilatometer. STRESZCZENIE: W artykule przedstawiono problemy związane z prawidłowym określeniem temperatur początku i końca przemiany eutektoidalnej w stalach podczas nagrzewania. Doniesienia literaturowe wskazują na istotny wpływ odległości międzypłytkowej w perlicie na powstawanie efektu dylatacyjnego związanego z zakończeniem przemiany eutektoidalnej na krzywych dylatometrycznych. W niniejszej pracy wykazano, że wystąpienie lub nie na dylatogramie nagrzewania efektu dylatacyjnego od końca przemiany eutektoidalnej w stalach podeutektoidalnych związane jest również ze zdolnością rozdzielczą użytego dylatometru. KEYWORDS: pearlitic transformation, dilatometric examinations, phase transformation temperatures, interlamellar spacing, hypoeutectoid steel. SŁOWA KLUCZOWE: przemiana perlityczna, temperatury przemian, badania dylatometryczne, odległość międzypłytkowa, stal podeutektoidalna
Successful venetoclax salvage in the setting of refractory, dialysis-dependent multiple myeloma with t(11;14)
Get PDFThis Case Report illustrates the ability to salvage high risk, multi-refractory t(11;14) patients with venetoclax. The depth of the response achieved indicates the importance of BCL-2 in mediating resistance in some patients with t(11;14) and suggests that at least in this patient population any risk of increased infection is likely justified by the potential benefit. Finally, our ability to administer this drug in the setting of ESRF argues for further studies evaluating the safety of venetoclax in patients with reduced renal function

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
La question de l’authenticité des meubles et le problème de leur conservation dans le premier musée polonais de Puławy
No full textL’application du critère d’authenticité aux vestiges du passé dépend entre autres de la spécificité de l’objet et du changement de son statut culturel. Présentant cette question à travers l’histoire de deux meubles provenant du premier musée polonais, l’auteur indique les sources d’inspiration des pratiques de conservation de l’époque.The way the criterion of authenticity was being applied in the evaluation of material relics did depend, among other things, on the kind of object and on the nature of its cultural status metamorphoses. The issue is discussed on the example of two pieces of furniture from the first Polish museum. The author analyses possible sources of inspiration for the conservation practice of that time
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
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
