Pengaruh Penambahan MasterGlenium ACE® 8595 dengan Pengurangan Kadar Air 37.5% dan Kadar Semen Rencana 409.80 kg/m3 Terhadap Kuat Tekan Beton
Full text linkMasterGlenium ACE® 8595 is a Type F chemical that serves to reduce the amount of mixing water, improve workability and improve concrete quality. The purpose of this study was to find out the effect of adding MasterGlenium ACE® 8595 with a reduction in water content of 37.5% and a plan cement level of 409.80 kg / m2. The research was conducted in the laboratory using the DOE (Department of Environment) method in accordance with SNI 03-2834-2000 with a test object in the form of a concrete cylinder diameter of 150 mm and a height of 300 mm. MasterGlenium ACE® 8595 tested on concrete age 7 days 3 sample, and 28 days 5 sample. Variations in the dose of addition of MasterGlenium ACE® 8595 used 0.54%, 0.81%, 1.08%, 1.35%, 1.62%, 1.89% and 2.16% of cement weight. The test results of a strong concrete press normal at 28 days amounted to 29.77 MPa. The test results of a strong concrete press normal at 28 days amounted to 29.77 MPa. The results of the test are strong concrete press with the addition of MasterGlenium ACE® 8595 amounting to 51.61 MPa, 53.53 MPa, 45.95 MPa, 49.80 MPa, 41.25 MPa, 40.80 MPa, and 39.27 MPa. Based on the results of the test, the use of MasterGlenium ACE® 8595 in concrete will increase the strength of the press, workability, and age coefficient

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

Pengaruh Penambahan Superplasticizer MasterGlenium ACE 8595 Terhadap Kuat Tekan dan Koefisien Umur Beton
No full textBahan tambah mineral merupakan bahan tambah yang dimaksudkan untuk
memperbaiki kinerja beton. Bahan tambah ini bertujuan untuk memperbaiki kinerja
workability, mengurangi panas hidrasi, mengurangi biaya pekerjaan beton, mepertinggi daya
tahan terhadap serangan sulfat, mempertinggi usia beton, mempertinggi kekuatan tekan
beton, mempertinggi keawetan beton, mengurangi penyusutan, mengurangi porositas dan
daya serap air dalam beton.
Berbagai jenis teknologi beton saat ini telah dikembangkan sesuai dengan
keperluannya, salah satunya beton mutu tinggi. Untuk mendapatkan hasil yang lebih
baik dilakukan dengan penambahan superplasticizer MasterGlenium ACE 8595. Hal
ini bukan sekedar untuk meningkatkan kemudahan pengerjaan saja, akan tetapi
mempengaruhi juga kenaikan persentase kekuatan tekan beton.
Disamping adanya kemudahan pengerjaan ada beberapa indikasi yang
diperhatikan seperti koefisien umur. Penting untuk mengetahui perubahan ini untuk
mengukur prediksi umur 28 hari pada umur lebih awal. Hal ini banyak diperlukan
untuk berbagai kebutuhan pengawasan, apakah mutu yang dipakai berkesesuaian
dengan nilai mutu yang direncanakan untuk 28 hari.
Dari hasil pengujian kuat tekan dengan penggunaan superplasticizer
MasterGlenium ACE 8595 menunjukkan peningkatan mutu dibandingkan mutu
rencana 42 mpa yaitu untuk 0.8%, 1.0%, dan 1.2% secara berturut-turut meningkat
sebesar 40.32%, 44.86%, dan 45.52%. Untuk angka koefisien umur pada umur 1 hari,
3 hari, dan 7 hari meningkat dibandingkan dengan koefisien umur PBI 1971.
Berdasarkan hasil pengujian maka kita mengetahui bahwa jika menggunakan
superplasticizer MasterGlenium ACE 8595 pada beton akan meningkatkan
workability, kuat tekan dan perubahan koefisien umurnya.Skripsi Sarjan
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
