Kandungan Klorofil a dan Karotenoid Rumput Laut Kappaphycus Alvarezii yang Dibudidayakan pada Kedalaman Berbeda
Get PDFTujuan dari penelitian ini adalah untuk menguraikan dampak pengobatan kedalaman budidaya yang berbeda terhadap klorofil dan karotenoid isi rumput laut K. alvarezii. Penelitian ini terdiri dari lima perlakuan dan setiap perlakuan terdiri dari tiga ulangan, akibatnya, ada 15 unit eksperimental. Rumput laut digantung dengan metode vertikal acak di kedalaman budidaya yang berbeda, mis 20 cm, 100 cm, 200 cm dan 400 cm. Analisis varians dilakukan pada tingkat 95%. Hasil penelitian menunjukkan bahwa kedalaman budidaya tidak signifikan defferent terhadap klorofil dan konten caratenoid. Klorofil dan karotenoid konten relatif tinggi di kedalaman 100 cm (0,013 mg / g-1 dan 0299 mg / g-1) dan terendah di kedalaman 20 cm (0.006 mg / g-1 dan 0163 mg / g-1 ).Kata kunci: klorofil a, karotenoid. kedalaman budidaya, rumput lautThe objective of the research was to elaborate the treatment impact of the different cultivation depths towards the chlorophyll a and carotenoid content of the seaweeds K. alvarezii. The research consisted of five treatments and each treatment consisted of three replications, consequently, there were 15 experimental units. The seaweeds were hanged by a random vertical method in the different cultivation depths, i.e 20 cm, 100 cm, 200 cm and 400 cm. Variance analysis was carried out on the 95% level. The results of the research indicates that the cultivation depths are not significantly defferent towards chlorophyll a and caratenoid content. The chlorophyll a and carotenoid content is relatively high in depth 100 cm (0,013 mg/g-1 and 0,299 mg/g-1) and the lowest is in depth 20 cm (0,006 mg/g-1 and 0,163 mg/g-1).Keywords: chlorophyll a, carotenoid. cultivation depths, Seawee
Intrapopulated Genetic Variation Of The Blue Swimming Crab (Portunus Pelagicus) From Kaimana, West Papua Indonesia Based On Cytochrome C Oxidase Subunit I (Co1) Gene Sequence
Get PDFThe first step to establishing appropriate broodstock management and conservation programs and to avoid decreasing genetic variability in this selective breeding program is the development of molecular genetic markers that can be used for evaluation of genetic stock determinations in gene flow rates. However, morphologically it is rather difficult to distinguish between one individual and another. The purpose of this study was to analyze genetic variation to prove differences in intrapopulated crabs. Small crab samples were collected from the district. Kaimana, West Papua. Morphological analysis was carried out by looking at differences in the color and pattern of white spots between one individual and another. The isolation of the crab CO1 gene was carried out by analyzing each individual after grouping it based on morphology. The results of the morphological analysis showed that males had seven color patterns and white carapace patterns while females had five color patterns and white spots on the carapace. However, there is little difference between morphology and genetics, especially in females, where the female is genetically divided into only two major groups. This indicates that there is information on phylogenetic relationships between individuals. The white spot on the carapace is genetically influenced so that it can be used to identify species or varieties, while the carapace color has not been shown to be influenced by the CO1 gene
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
