Potential use of Zataria multiflora essential oil to control postharvest Aspergillus flavus fruit rot of strawberry
Get PDFPostharvest fruit rot is a major problem in strawberry production chain worldwide. Aspergillus sp. is one of the major fungi associated with fruit rot of strawberry. In this study, an Aspergillus flavus was isolated from a rotten strawberry fruit. Based on the nucleotide sequence analysis of the internal transcribed spacer regions of rDNA, the fungus was confirmed as A. flavus. Pathogenicity of the isolated fungus was confirmed by artificially inoculating strawberry fruits under laboratory conditions. This strain was capable of producing aflatoxin B1 in vitro as determined by liquid chromatography-mass spectrometry analysis. Postharvest dip treatment of mature strawberry fruits with Zataria multiflora essential oil (ZEO) (0.1%) completely suppressed A. flavus infection and prevented rotting of fruits. The results of this study suggest that ZEO can be used as a sustainable and safe alternative to chemical fungicides for the control of Aspergillus fruit rot of strawberry
Antagonistic bacterial strains isolated from cabbage rhizosphere release antimicrobial volatile organic compounds against Pythium aphanidermatum
Get PDFIn a previous study, we isolated four antagonistic bacterial strains viz., Pseudomonas aeruginosa B1-SQU, Pseudomonas indica B2-SQU, Serratia marcescens B3-SQU and Pseudomonas brenneri B4-SQU from the rhizosphere of cabbage which suppressed damping-off in cabbage caused by Pythium aphanidermatum. In this study, potential of these bacterial isolates to produce antimicrobial volatile organic compounds (VOCs) against P. aphanidermatum was tested. The results of the two-sealed-base-plates assay revealed that all four bacterial strains produced VOCs against P. aphanidermatum with the maximum inhibition with P. brenneri B4-SQU followed by S. marcescens B3-SQU, P. aeruginosa B1-SQU and P. indica B2-SQU. Solid-phase microextraction coupled with gas chromatography-mass spectrometry was used to profile the VOCs of bacteria. A total of 20 VOCs were detected in P. aeruginosa B1-SQU and the major compounds identified were Carbon dioxide, 1-Butanol, 3-methyl- and Disulfide, dimethyl. The main volatile compounds detected in P. indica B2-SQU were 1-Butanol, 3-methyl-, Disulfide, dimethyl and 1,2-Propanediamine. Disulfide, dimethyl and 1,2-Propanediamine were the predominant compounds identified in S. marcescens B3-SQU among others. The major compounds detected in P. brenneri B4-SQU were 1-Butanol, 3-methyl-, 1,2-Propanediamine and Disulfide, dimethyl. Dimethyl disulfide, a well-known antimicrobial compound, was detected in the volatile profiles of all four antagonistic bacterial isolates. These results suggest that VOCs of antagonistic bacteria may be involved in the suppression of P. aphanidermatum and these antagonistic bacterial strains may be used as biofumigants for controlling damping-off of cucumber
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
