Physicochemical and Sensory Properties of Pumpkin (Cucurbita moschata D) and Arrowroot (Marantha arundinaceae L) Starch-based Instant Porridge
Get PDFPumpkin is a potential source of vitamin A and antioxidant. Arrowroot starch as the source of carbohydrates contains a low glycemic index. However, the utilization of pumpkin and arrowroot starch as the source of food products is still limited. Both ingredients can be processed into nutritious food with practical servings. The objective of the research was to investigate the effect of pumpkin and arrowroot starch ratio and the rotation speed of the drum dryer on the physiochemical properties and the acceptability of the instant porridge. The various ratios of pumpkin and arrowroot starch in the study were 1:1, 2:1, 3:1, 4:1, and 5:1. The process of making instant porridge from pumpkin and arrowroot starch was using a drum dryer with a rotation speed at 1 and 1.5 rpm and a saturated steam pressure at 1 bar. The porridge yield was tested for physiochemical properties and acceptability. The variables of pumpkin to arrowroot starch and the rotation speed of the drum dryer affected the physical and chemical properties, and the acceptability of the instant porridge yielded. Based on amylograph characteristics, the instant porridge had amylograph profile type C, except on pumpkin and arrowroot starch in a ratio of 5:1 with drum dryer rotation speed at 1 rpm. Â The best and most acceptable instant porridge according to the panelists was obtained at the ratio of 5:1 with 1.5 rpm speed.Â

Get PDFThe Salacca fruits were stored at modified atmospheric condition in the impermeable bottle with the variations of concentration of oxygen at 5, 10, 15, and 20%, carbon dioxide at 0, 5, 10, and 15%, nitrogen at 65, 75, 80, 85 and 95%, and the variations of temperature at 5, 10, 20, and 28°C. The gases within the bottles were replaced weekly.
The results showed that the models of concentration change of sucrose, glucose and fructose i.e. CS = 2,392 Cc02-0\u27064 CO2°\u27"2 exp (-0,263 t), Cg = 1,575

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
Model respirasi buah salak pondoh (Salacca zalacca cv. Pondoh) yang disimpan dalam atmosfer termodifikasi berdasarkan kinetika enzim
Get PDFThe salacca (Salacca zalacca cv. Pondoh) fruits were stored in various modified atmosphere conditions in the impermeable cuverles with the variation of oxygen concentration of 2, 4, 6 and 8%. carbon dioxide concentration of 1, 2. 3 and 4% and nitrogen concentration as the rest. The variation of temperature was 12, 20 and 24 C. Gases within each cuvette were replaced daily. The respiration rate of the fruit was mudded based on the enzyme kinetic theory.
The result showed that the respiration model Mows the Michaelis-Menten enzyme kinetic, with CO2 as the uncompetitive inhibitor. The model was fit to predict the respiration rate of the fruit.
