Corrosion inhibitors for steel in concrete – an update
No full text16 anni fa un primo stato dell’ arte “Inibitori di corrosione per il calcestruzzo armato” è stato pubblicato come EFC numero 35. Gli inibitori di corrosione vengono utilizzati maggiormente come tecnica preventive, dunque aggiunti durante l’impasto del calcestruzzo. In questo caso i risultati di prove in laboratorio ed il comportamento in pratica indicano che il tempo di innesco di corrosione viene prolungato da un fattore di circa due. La riduzione della velocità di corrosione invece non è significativo. Inibitori applicati sul calcestruzzo indurito come sistema di ripristino hanno mostrato risultati positivi solamente a tenori di cloruro bassi e quando la corrosione è in fase iniziale.16 years ago a first state of the art report “Corrosion Inhibitors for Steel in Concrete” has been published as EFC publication No. 35. Industry continued to develop and improve admixtures that can be added to the fresh concrete (preventative) or systems that can be used as surface applied inhibitors (curative). This paper presents an update on the state of the art on corrosion inhibitors, with particular emphasis on long-term and especially field studies. There is a general agreement from both laboratory and field studies that mixed-in corrosion inhibitors can delay the onset of chloride-induced corrosion in good quality concrete by a factor of about 2. The reduction of the corrosion rate once corrosion has initiated appears to be much less significant. Surface applied inhibitors can show positive results only at low chloride concentrations and with beginning corrosion

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

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

Author, publisher and bookseller : a tripartite synergy in Nigerian book industry
No full textThis work is about the roles of Author, Publisher and Bookseller in Book development in
Nigeria. The paper started by delving into the history of Book Publishing in Nigeria after
which it proceeded by defining who an author, a publisher, and a bookseller is and
expatiated on the indispensable roles of these key actors in Nigerian Book Industry and in
the emerging Information Society. Furthermore, the various constraints to book
development were identified while the paper advised on how the Book Industry can be
further promoted in Nigeria. However, the paper concluded and made recommendations
on how the Book sector can help in enhancing scholarship in the country
A self-conscious Kurt Vonnegut: an analysis of Cat's Cradle, Slaughterhouse-Five and Breakfast of Champions
No full textThe works of Kurt Vonnegut stand as seminal in the American literary canon. Looking at three of his most influential novels, namely Cat's Cradle, Slaughterhouse-Five and Breakfast of Champions, this study aims to better understand the mechanisms which inform his fiction. Working chronologically through the novels, the study examines historical context, narrative technique, theoretical underpinnings and the social critique of each novel. Guided by an idea of the postmodern novel the study examines how these elements interact, concluding that by way of what may be considered "simple" yet self-conscious metafiction and prose as well as variations in narrative technique, Vonnegut is able to more accurately convey his opinions on the American situation as well as demonstrate his stance on the role of fiction and the writer in contemporary society. The study also considers closely the role of the reader and the author/reader/text relationship
