Development of Natural vegetable sanitizer from Thai local herbs
Nowadays, food safety becomes public concern, especially in fresh produce; fresh vegetables and fruits. The CDC has been reported at least 7 outbreaks from fresh produce in the past 3 years; for example, Escherichia coli O121 in raw clover sprouts (2014), E. coli O157:H7 in ready-to-eat salads (2013), Salmonella Saintpaul in cucumbers (2013), Salmonella Typhimurium and Newport in cantaloupe (2012), and E. coli O157:H7 in spinach and spring mix salad (2012). Washing, before consuming, is the most important step in order to prevent foodborne outbreak in fresh produces. Therefore, this research was aimed to develop vegetable sanitizer from crude extracts of Acacia concinna (Willd.) D.C (Som-poi), Capsicum annuum (Chili), Cymbopogon citratus (Lemongrass), Citrus hystrix (Kaffir lime) and Chrysanthemum indicum L. (Chrysanthemum) in order to reduce foodborne bacteria in fresh vegetable. These herbs have been reported for their antibacterial activity (Pitinidhipat and Yasurin, 2012; Utami et al., 2012; Saenghiruna and Yasurin, Lazuardi et al., 2013; 2013; Piya-isarakul and Yasurin, 2013; Saenghiruna et al., 2014; Dung et al., 2014). The 18 treatments with 3 different crude extracts percentage (0.5, 1 and 1.5%), 3 different
volumes (3, 5, and 10 ml.) and 2 different soaking times (10 and 20 min) were investigated for their antibacterial synergistic activity using Lactuca sataiva (Lettuce) as vegetable model. The MPN, total place count on PCA, BHI agar for Listeria monocytogenes count, and SS agar for Salmonella sp. count were used to evaluate the antibacterial efficiency of vegetable sanitizer. The results showed that treatment 18 (using 10 ml of 1.5% crude extracts with 20 min soaking time) gave the highest bacterial efficiency statistically by vegetable sanitizer comparing with the commercial brand. The MPN number, the total plate count, and the L. monocytogenes count were 1.34 ±0.19 MPN/ml, 1.62 ± 1.02 log CFU/ml, and 1.31 ± 0.40 log CFU/ml, respectively. The Salmonella sp. was not found. The t-test has been done by using SAS on log CFU/ml with P0.05. It was found that crude extract percentage, used volume, and soaking time affected the antibacterial efficiency of this vegetable sanitizer
Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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
We 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
We 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
