Conversion of glycerol to glycerol carbonate using heterogeneous base catalyst derived from Oil Palm Kernel Shell Biochar (OPKSB) / Muhammad Sofwan Hashriq Mohammad Shukor
Get PDFThe surplus of crude glycerol (GL) has led to a decrease in its price and poses challenges for its disposal. To promote the development of the biodiesel (BD) industry, it has become focus of the researchers to convert GL into value-added chemicals. Glycerol carbonate (GC) is one of the value-added compounds that can be synthesized by the transesterification of GL. This study was conducted to utilize the waste of by-products from both the oil palm industry as well as the biodiesel industry for industrial purposes. The synthesis of GC through transesterification of GL and dimethyl carbonate (DMC) catalyzed by treated oil palm kernel shell biochar (OPKSB) with 20% potassium hydroxide (KOH) at 400°C, 500°C, 600°C, 700°C, and 800°C calcinations temperature has been studied. The chemical composition of untreated and treated OPKSB along with the final product obtained through transesterification reaction have been analyzed using ATR-FTIR. Scanning electron microscopy (SEM) was utilized to investigate the morphology, size, and clustering of the catalyst particles. Furthermore, Energy- dispersive X-ray (EDX) analysis was employed to ascertain the inorganic elemental compositions of both treated and untreated biochar. The prepared catalyst calcined at 700°C (OPKSB-700) shows the best performance with 54.51% potassium (K) weight obtained from EDX analysis before undergoing the reaction indicating a higher basic site for catalytic activity for transesterification reaction. OPKSB-700 displayed a very porous surface morphology with a rod-like structure on the biochar surface observed at 3000x magnification using SEM. Not to mention, all the catalysts can catalyze transesterification reactions; under reaction temperature of 110°C, reaction time of 90 min, GL: DMC molar ratio of 1:3 and 3% of catalyst loading, based on FTIR results. The appearance of the peak at 1770 cm-1 and a broad peak at 3300 cm-1 which correspond to C=O and O-H groups respectively, signifies the success of the transesterification reaction, into the desired product. Qualitative analysis using thin layer chromatography (TLC) showed GC spot clearly observed for all of the sample (reaction), indicated that GL have completely converted to GC. The results of TLC showed that, calcination pre-treatment has significantly provide sufficient actives site and catalytic surface, thus promoting towards increase of the catalytic activity in the transesterification reaction. The current study has opened a broad understanding towards application of biochar as potential catalyst in organic reaction

In this study, researchers used a survey method that aims to strengthen the analysis of the needs for the use of information and communication technology among elementary school teachers in the city of Jambi and to support teacher tasks, which are increasingly challenging the future for effective technology integration that involves content aspects. pedagogical and subject in Indonesia in general, and Jambi city in particular. The population in this study were all teachers in the city of Jambi. This study began with 107 respondents filling the pilot study questionnaire online, followed by taking the main data sample with 892 respondents who completed filling out the questionnaire / questionnaire online. The analytical test for the pilot study was carried out using Face and content validity, Exploratory Factor Analysis (EFA), Partial Least Square Structural Equation Modeling (PLS-SEM), and continued with the MANOVA test to see differences on the demographic side of the main survey data
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
