The Effect of Variations of Cane Sugar and Citric Acid Concentrations on the Physical Chemical and Organoleptic Characteristics of Pumpkin (Cucurbita Moschata) Syrup
Get PDFLabu kuning (Cucurbita moschata) merupakan tanaman komoditas yang memiliki kandungan gizi sangat tinggi, produksinya melimpah, dan harganya terjangkau, namun pemanfaatannya belum maksimal. Sirup merupakan produk olahan yang berbahan baku gula dan air dengan persyaratan kadar air gula minimal 65%. Sirup berbahan baku labu kuning dengan penambahan bahan tambahan pangan berupa gula, Carboxyl Methyl Cellulose (CMC), asam sitrat dan jeruk nipis. Variasi konsentrasi pada gula 65% dan 70% dan asam sitrat 0%, 0,1%, 0,3%, dan 0,5% diharapkan dapat memberikan pengaruh terhadap pH, total padatan terlarut, gula reduksi, kadar vitamin C, dan kadar betakaroten. Tujuan penelitian sirup labu kuning yaitu mengkaji dan menentukan konsentrasi gula tebu dan asam sitrat terhadap sifat fisikokimia, dan organoleptik. Metode yang digunakan dalam penelitian ini yaitu uji pH (metode pH meter), total padatan terlarut (hand refractometer), gula reduksi (metode Nelson-Sumogyi), vitamin C (metode iodimetri), kadar betakaroten (metode spektrofotometer), sedangkan organoleptik menggunakan uji sensori. Berdasarkan hasil penelitian diketahui bahwa variasi penambahan gula dan asam sitrat memiliki pH 3,50-5,86; total padatan terlarut 10,33-11,4 (obrix); gula reduksi 19,4%-30,21%; kadar vitamin C 20,53-38,13 (mg/100g); dan kadar betakaroten 1,24-2,82 (mg/100g). Pada perlakuan penambahan gula 65% dan asam sitrat 0,5% (A1B3) memiliki penilaian yang disukai panelis berdasarkan parameter aroma, warna dan rasa sirup labu kuning.Pumpkin (Cucurbita moschata) is a commodity plant that has very high nutritional content, abundant production, and affordable price, but its utilization is not maximized. Syrup is a processed product made from sugar and water with a minimum sugar water content requirement of 65%. A syrup made from pumpkin with the addition of food additives in the form of sugar, Carboxyl Methyl Cellulose (CMC), citric acid and lime. Concentration variations on sugar 65% and 70% and citric acid 0%, 0.1%, 0.3%, and 0.5% are expected to have an effect on pH, total dissolved solids, reducing sugar, vitamin C content, and levels of Beta carotene. The research objective of pumpkin syrup is to study and determine the concentration of cane sugar and citric acid on physicochemical and organoleptic properties. The methods used in this study were pH test (pH meter method), total dissolved solids (hand refractometer), reducing sugar (Nelson-Sumogyi method), vitamin C (iodimetric method), beta- carotene content (spectrophotometer method), while organoleptic use sensory test. Based on the results of the study, it is known that the variation of the addition of sugar and citric acid has a pH of 3.50-5.86; total dissolved solids10.33-11.4 (obrix); reducing sugar 19.4%-30.21%; vitamin C levels 20.53-38.13 (mg/100g); and beta-carotene content of 1.24-2.82 (mg/100g). In the treatment of adding 65% sugar and 0.5% citric acid (A1B3), the panelists preferred an assessment based on the parameters of aroma, color and taste of pumpkin syrup
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

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
