Pengaruh Air Rebusan Terhadap Kualitas Ikan Gembung Rebus (Restrelinger sp)
Get PDFTelah dilakukan uji bakteri pada air rebusan ikan kembung rebus (Rastelliger sp) yang penggunaan airnya tidak diganti dan digunakan secara terus menerus dalam beberap tahapan, dengan tujuan untuk mengetahui pengaruh terhadap kualitas ikan yang produksi. dan melihat pengaruh terhadap tektrus daging, warna insang, dan aroma yang ditimbulkan. penelitian ini menggunakan metode deskriptif kualitatif. Na digunakan untuk menghitung jumlah bakteri, jumlah koloni pada air sebelum perebusan dan sesudah perebusan, ikan kembung juga sebagai sumber nutrisi untuk tempat perkembangbiakan bakteri sehingga berdampak negatif pada kualitas produksi.Bacterial tests have been carried out on boiled water for boiled mackerel (Rastelliger sp) whose water usage is not replaced and is used continuously in several stages, with the aim to determine the effect on the quality of fish production. and see the effect on meat tectrus, gill color, and aromas. This study used descriptive qualitative method. Na is used to count the number of bacteria, the number of colonies in water before boiling and after boiling, mackerel as well as a source of nutrition for breeding grounds for bacteria so that it has a negative impact on the quality of production
北スマトラ州のベラワン市とタンジュンプラ市の貝類(Anadara Antiquata)の形態計測の比較
No full textKerang bulu (Anadara antiquata) banyak dikonsumsi di Sumatera Utara, namun belum diketahui dari dasar mana ukuran daging yang paling berat. Penelitian ini bertujuan untuk mengetahui berat daging dan morfometri cangkang kerang bulu A. Antiquatan yang berasal dari perairan Belawan dan Tanjung Pura. Parameter pengamatan berat daging kerang (Y) sebagai variabel terikat, panjang cangkang (x1), tinggi (x2), lebar cangkang (x3), berat cangkang (x4) sebagai variabel bebasnya. Analisis statistik yang digunakan yaitu regresi berganda metode enter dan perbedaan morfometri kerang dari kedua daerah dengan uji t. Hasil penelitian di Belawan statistik persamaan regresinya adalah; Y = 0,9 X1 + 3,6 X2 + 3,2 X3 - 0,2 X4 - 13,3 dan statistik persamaan regresi di Tanjung Pura adalah; Y = 0,96 X1 – 0,56X2 + 0,61X3 + 0,41X4 – 3,33. Morfometri didasarkan umur yang sama dari kedua lokasi menunjukkan adanya perbedaan berat daging (y) p=0,000, panjang cangkang (x1) p=0,003, tinggi (x2) p=0,002, berat cangkang (x4) p=0,000, sedangkan lebar cangkang (x3) tidak berbeda nyata p=0,252. Daging kerang dari Belawan lebih berat dibandingkan dari Tanjung PuraMandarin abstract: 毛皮壳（Anadara antiquata）在北苏门答腊广泛消费，但目前尚不知道最重的肉的大小。本研究旨在确定源自Belawan和Tanjung Pura水域的A. Antiquatan贝类贝壳的肉重和形态测定。观察到的参数是作为因变量的贝类（Y）的重量，壳的长度（x1），高度（x2），壳宽（x3），壳重（x4）作为自变量。使用的统计分析是通过t检验的多元回归输入方法和来自两个区域的壳的形态测量差异。 Belawan研究的结果是回归方程的统计数据; Y = 0.9 X1 + 3.6 X2 + 3.2 X3 - 0.2 X4 - 13.3，Tanjung Pura的统计回归方程为; Y = 0.96 X1-0.56X2 + 0.61X3 + 0.41X4-3.33。基于相同年龄的两个位置的形态测量显示肉重（y）p = 0,000，壳长（x1）p = 0.003，高度（x2）p = 0.002，壳重（x4）p = 0,000，而壳宽（x4）的差异x3）没有显着差异p = 0.252。 Belawan的蛤肉比Tanjung Pura重。English : Anadara antiquata clams are widely consumed in North Sumatra, but it is not yet known from what basis the heaviest meat size. This study aimed to determine the meat weight and morphometry of the clam A.antiquatan shell from Belawan and Tanjung Pura sea waters. The observation parameters in this study were clam meat weight (Y) as the dependent variable, shell length (X1), height (X2), shell width (X3), shell weight (X4) as the independent variable. Statistical analysis used was multiple regressions by Entering method and clam morphometry difference from both regions with t-test. Statistical results of the regression equation in Belawan was; Y = 0,9 X1 + 3,6 X2 + 3,2 X3 - 0,2 X4 - 13,3 and in Tanjung Pura was; Y = 0.96 X1 - 0,56X2 + 0,61X3 + 0,41X4 - 3,33. The morphometry based on the same age of both regions indicated a difference in the meat weight (Y) p = 0,000, the shell length (X1) p = 0.003, height (X2) p = 0.002, shell weight (X4) p = 0,000; while shell width (X3) did not differ significantly p = 0.252. Thus, the clam from Belawan was heavier than Tanjung Pura's.Japan Abstract : 貝類（Anadara antiquata）は北スマトラで広く消費されているが、どのサイズから肉のサイズが最も重いかはまだ理解できない。本研究の目的は、Aの肉と貝の殻の形態計測の重量を決定することである。それはベラワン市とタンジュンプラ市の水域に由来するアンチクタン（Antiquatan）である。観測されたパラメーターは、独立変数としての貝の重量（Y）、シェルの長さ（x1）、高さ（x2）、シェル幅（x3）、シェル重量（x4）でした。使用された統計分析は、重回帰入力法とt検定による両方の領域からのシェルの形態計測の違いであった。

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
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
