Influence of soya oil blended with fish oil on growth performance and lipid profile of red sea bream pagrus major
No full textboth BWG and SGR in 4F6S were significantly lower than other treatments. Feed conversion ratio (FCR) and feed intake (FI) showed no significant differences among treatments. Survival rate of all treatments exceeded 90% although the hepatosomatic index (HSI) in 4F6S was significantly higher than other treatments and serum glutamic-oxaloacetic transaminase (GOT) increased gradually with a higher inclusion of soya oil. Lipid deposition in the whole body was the highest in fish fed with dietary 10F and decreased in relation to the elevated concentration of soya oil in diets. The ventral muscles had doubled the amount of lipid deposition as compared to dorsal muscles. Dominance of saturates among total fatty acid composition particularly C16:0, was similarly observed in the dorsal and ventral muscles as well as the liver. Saturates, monoenes, n-3 and ratio of n-3/n-6 observed have a similar gradient degradation in the dorsal and ventral muscles and the liver. An inverse relationship of inclusion level of soya oil on eicosapentanoic acid (EPA) and docosahexanoic acid (DHA) in both dorsal and ventral muscles including the liver was also observed. In conclusion, diets not exceeding 40% soya oil are suitable as fish oil replacement in the diet of juvenile red seabream without significantly affecting the overall growth performance of this fish
Dried acetes as growth promoter for guppy (Poecilia reticulata) nutrition
No full textAcetes is a marine shrimp that is still an under-studied source as feed ingredient for tropical
ornamental fish. Ornamental fish is regarded as pet fish due to its mystic attractiveness for pet fish
enthusiasts and requires good protein source to attain good growth and skin colour enhancement. The
prevailing feed industry due to continuos pandemic has resulted many enthusiasts to look for
alternative growth promoter as feed for guppy. The aims of this study were to determine the
nutritional composition in dried Acetes and to investigate the effects of dietary dried Acetes meal on
growth performance of Guppy (Poecilia reticulate). Five dietary isocaloric feeds namely Tcontrol
(commercial feed only), T0 (100% commercial feed and 0% of dried Acetes.), T1 (75% commercial diet
and 25% of dried Acetes spp.), T2 (50% commercial diet and 50% of dried Acetes), T3 (25% commercial
diet and 75% of dried Acetes) and T4 (0% commercial diet and 100% of dried Acetes) were formulated as
feed for juveniles of Guppy (Poecilia reticulata) reared in triplicates for 30 days. Growth indices like
Body Weight Gain, Feed Conversion Rate, Feed Intake and Survival Rate were observed in every 10
days. Results indicated that T4 with 100% dried Acetes attained a significantly high BWG of 222.6% with
low feed intake and FCR of less than 3.5. It can be concluded that inclusion of 50 to 100% dried Acetes
in feed has contributed to optimal growth performance of guppy. It is also recommended that further
studies on dietary Acetes could be done to examine other properties that could be further developed as
superfeed for ornamental fish and thereby enhance growth and productivity of the ornamental fish
industry as well as economic efficiency
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
