EFFECT OF GROUND GRANULATED BLAST FURNACE SLAG (GGBFS) UTILIZATION AS PARTIAL REPLACEMENT OF FINE AGGREGATE ON SUBBASE COURSE CBR VALUE
Full text linkThe construction of road infrastructure is one of the priority of the current government. The construction will need high quality material that may be scarce and not available in the construction site. At the same time, the manufacturing of iron in Indonesia results in production of ground granulated blast furnace slag (GGBFS) in big amount that needs to be utilized. Thus, the objective of this research is to know about the effect from the utilization of GGBFS as partial replacement of fine aggregate on subbase course value with the variation of fine aggregate replacement with GGBFS on the subbase CBR value on unsoaked condition. The GGBFS was used to replace 0%, 15%, 30% and 45% of the fine aggregate weight. The result of the CBR test shows that every variant fulfil the required CBR value of 35%. Moreover, the replacement of fine aggregate with GGBFS increases the CBR value on unsoaked condition, with 30% replacement of fine aggregate with GGBFS being the optimum condition. On 45% replacement of fine aggregate with GGBFS, the CBR value starts to decrease. Another effect from the replacement of fine aggregate with GGBFS on subbase course is that the optimum moisture content (OMC) and the maximum dry density (MDD) will change. With more GGBFS content in the mixture, the optimum dry density (OMC) will decrease. On the other hand, as the content of GGBFS in the mixture increase, the Maximum Dry Density (MDD) of the mixture will also increase accordingly. With the increase in CBR value, the subbase layer structural coefficient will also increase. Further study needs to be done to investigate the effect of fine aggregate replacement with GGBFS on subbase CBR soaked condition. Then, the effect of curing time on the subbase mixture with fine aggregate replacement with GGBFS should also be evaluate
POTENTIAL OF FAST FIRE SPREAD IN LARGE COMPARTMENTS WITH EXPOSED TIMBER
No full textAlthough research on wooden materials has been carried out for decades, there is still a lack of test data for really large experiments, and especially with high ceiling heights. This is problematic as CLT now is used in a variety of different rooms, including open-plan offices, lobbies, canteens, dwellings, kindergartens, schools, etc. In other words, the great variation in the use of CLT, including room size, geometry, and orientation, challenges the current understanding of how exposed CLT affects a fire in really large compartments. This paper presents some unpublished experimental data of a large-scale auditorium test in a wooden corner configuration, and insights from the fire development of a fire in a school gym with several wooden surfaces

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
Full text linkWe 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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
