    ABSTRACT The main component of poultry eggshell composition is CaCO3 which has potential to be a source of calcium. As food waste, poultry eggshells contain harmful components, organic compounds and the characteristic are rough, hard, flavorful fishy and have a les attractive color when used as food. The immercion process with chemical solution is known to improve the characteristics and purify the calcium level of eggshell flour. The general purpose of this research is to know the influence of solvent type on calcium level and physical characteristic of poultry eggshell flour. The method of research is experimental type using factorial completely randomized design, consist of 2 factors 16 treatments, namely type of solvent (HCl, CH3COOH, NaOH and H2O) and egshell species (chicken races, free-range chicken , duck and quail). Each treatment was repeated 3 times to obtain 48 units of experiments. Data on test results of calcium levels and physical characterstic analyzed using ANOVA statisticmethod followed by advanced test DMRT. The results shows a very real influence from the type of solvent and eggshell to the calcium level and physical characteristics of eggshell flour. Duck eggshell with CH3COOH soaking solution produce calcium level and physical characteristic of the best eggshell flour. Keywords: Eggshell, solvent, calcium, physical characteristi

    Tujuan penelitian ini adalah untuk mengetahui profil tepung Foxtail millet (TFM) varietas lokal Majene termodifikasi melalui proses fermentasi ekstrak kubis terfermentasi (EKT). Bakteri asam laktat (BAL) pada EKT memiliki kemampuan yang sangat baik untuk memperbaiki sifat fungsional dan fisikokimia TFM. Biji Foxtail millet yang telah disosoh selanjutnya dimodifikasi menggunakan EKT (0, 12, 24, 36, dan 48 jam), kemudian dikeringkan hingga diperoleh TFM. Hasil penelitian menunjukkan modifikasi TFM melalui fermentasi EKT berpengaruh terhadap profil tepung yang dihasilkan. Peningkatan waktu fermentasi dari 0 ke 48 jam menyebabkan penurunan pada kadar abu (1,41 - 1,22 %), kadar lemak (2,93 - 2,46 %), kadar serat (4,33 - 3,45 %), derajat putih (71,02 – 67,94), kadar pati (66,38 – 59,95 %), dan densitas kamba (0,77 – 0,48 g/cm3), serta peningkatan pada kadar air (8,36 – 9,18 %), kadar protein (10,36 – 12,73 %), kadar amilosa (17,82 – 20,85 %), kelarutan (13,55 – 19,77 %), daya kembang (12,85 – 17,13 %), kapasitas penyerapan air (1,32 – 1,83 g/g), kapasitas penyerapan minyak (1,02 – 1,23 g/g) dan daya cerna pati (16,33 – 51,63 %). Kesimpulannya, profil TFM lokal varietas Majene dapat diperbaiki dengan proses fermentasi selama 48 jam menggunakan EKT

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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 link
    We 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 link
    We 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 text
    We 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
