Optimisation of cholesterol reduction in squid by saccharomyces cerevisiae using response surface methodology (RSM) / Nor Zafirah Abdullah @ Zulyadain
Get PDFThe purpose of this study was to optimise the cholesterol reduction in squid by yeast extract glucose peptone (YEGP) broth containing Saccharomyces cerevisiae using Response Surface Methodology (RSM) of MINITAB Software (Version 14). Experimental design was created by RSM whereby test variables; pH of YEGP broth, concentration of S. cerevisae (%), incubation temperature (0C) and incubation time (hours) were used. Whole part of squid were blended and mixed thoroughly in different pHs of broth containing different concentrations of S. cerevisae and treated differently in terms of incubation temperature and incubation time as suggested by the experimental design of RSM. The optimal centrifugal speed was investigated and relative centrifugal field (RCF) of 1000 x g at the temperature of 2o C for 10 minutes showed the best performance. This speed was able to give 33.51% reduction in total fat content of squid. This centrifugation condition was used to determine the optimum amount of cholesterol reduced in treated squid. Cholesterol analysis was carried out according to AOAC Official Method 994.10 and measured using Gas Chromatography: with Flame Ionization detector (GC-FID). Cholesterol content in squid was reduced to 77.49% at the optimum condition; pH 3.76 of broth, 0.6% concentration of S. cerevisae, 35.1 0C of incubation temperature and 22 hours of incubation time. Verification experiment was also carried out and it was found that there was no significantly different at the 5% level between predicted and verified values of cholesterol reduction using the optimum condition determined by RSM. In addition, the significant regression equation or model at the 5% level of confidence was also established for the estimation of the percentage reduction of cholesterol in squid treated by S. cerevisiae. This indicates that S. cerevisiae is a potential source to be employed to reduce cholesterol in squid
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
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
MENIMBANG KONTORVERSI PEMAKNAAN KONSEP AHL AL-KITĀB DALAM AL-QUR’AN
No full textAbstract: One of the controversy-laden terms in the discourse of Islamic theology is ahl al-Kitab. Different ways of interpreting the term through textual and contextual exegesis of the Qur’an verses concerning it have colored the history of Muslim beliefs about other religion and religious communities. This paper aims to probe the controversies and arguments through revealing paradigms that underlies any views that differ from each other. Compromising the controversy was considered very important. Therefore, in the context the difference of textual and contextual interpretation of the term, the author conclude that both interpretations should be understood as mutual inclusion rather than two separate points in terms of mutual exclusion. Textual interpretation discovers basic, objective meaning of the term in Qur'an, while the contextual interpretation discovers its contextual meaning, both linguistic and socio-cultural.Abstrak: Salah satu term yang sarat kontroversi dalam diskursus teologi Islam ahl al-kitāb. Variasi pemaknaan term itu melalui tafsir tekstual dan kontekstual atas ayat-ayat al-Qur’an yang berkenaan dengannya telah mewarnai sejarah keyakinan umat Islam tentang agama dan komunitas agama lain. Tulisan ini bertujuan untuk menelisik kontroversi-kontroversi itu dengan menyingkap argumen dan paradigma yang melandasi setiap pandangan yang saling berbeda itu. Mengarifi kontroversi itu dipandang sangat penting. Oleh karena itu, dalam perbedaan konteks tafsir tekstual dan kontekstual atas term itu, penulis berkesimpulan bahwa dua tafsir itu harus tidak dipahami sebagai dua titik yang terpisah, melainkan dua hal yang menyatu. Tafsir tekstual menemukan makna awal-objektif terma itu dalam al-Qur’an, sedangkan tafsir kontekstual menemukan makna kontekstualnya baik secara linguistik maupun sosial-kultural yang melingkupinya.</p
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
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
