Effect of corm size and growth regulators on growth, flowering and quality of gladiolus (Gladiolus grandiflorus L.)
No full textGladiolus is the 8th most important in the world cut flower trade grown for its elegant attractive spikes and good keeping quality. However, the farmers in Bangladesh have limited access to the scientific cultivation of this crop, and yield and quality production of flower is low compared to other gladiolus growing countries in the world. Growth regulating chemicals have been reported to be very effective in manipulating growth and flowering of gladiolus. Therefore, an experiment was conducted at the Landscaping section of the Department of Horticulture, Bangladesh Agricultural University, Mymensingh, during the period from October 2017 to April 2018 to study the effect of corm size and growth regulators on growth, flowering and quality of gladiolus (Gladiolus grandiflorus L.). The experiment consisted of two corm sizes viz., 3-4 and 4-5 cm, and two growth regulators viz., GA3 @ 250, 500 and 750 ppm, and NAA @ 100, 200 and 300 ppm along with water as control. The two-factor experiment was laid out in a randomised complete block design with three replications. The results revealed that the corm size and growth regulators at different concentrations significantly affected various growth, floral and quality traits of gladiolus. The highest plant height, maximum number of leaves per plant, longest leaf length, maximum number of florets per spike, longest spike and rachis length were observed in 4-5 cm sized corms and GA3 @ 750 ppm, compared to rest of the treatments. Earliness in flower initiation and maximum duration of flower was observed in 4-5 cm sized corms and GA3 @ 500 ppm. Significant variations among the treatment combinations were observed for all the parameters studied. The treatment combination of 4-5 cm sized corms and GA3 @ 750 ppm was found to be best in respect of growth, floral and quality characters of gladiolus. [Fundam Appl Agric 2018; 3(3.000): 596-601

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
Effects of shrimp chitosan based edible coating on the shelf life of selected vegetables in context of attaining SDGs
No full textVegetable spoilage and post-harvest losses are worldwide issues that diminish quality, nutritional content and marketability, hence exacerbating food waste and threatening food security, particularly in agriculturally dependent countries like Bangladesh. Polysaccharide coatings, particularly chitosan, have gained popularity as biopolymer-based coatings for prolonging the postharvest shelf life of fruits and vegetables, owing to their biodegradable and non-toxic properties. This study aimed to assess the characteristics of chitosan obtained from shrimp (Penaeus monodon) shells and uses it as coatings to prolonging the shelf life of tropical vegetables. The extraction and characterization of chitosan as well as its effect on the shelf life of vegetables were evaluated. The study yielded approximately 20.85 ± 0.01 % of chitosan from the shrimp shell. The moisture content, WBC and FBC were 8.68 ± 0.01 %, 564.67 ± 4.73 % and 518.00 ± 5.57 % respectively. The intrinsic viscosity of chitosan was 20.74 dL/g with a molecular weight of 114.01 kilodaltons (kDa). The solubility of the chitosan was 99.90 % ± 0.10 % with a DD of 95.88 ± 0.70 %. The FTIR spectra of the chitosan sample were measured with specific peaks at 3410.96 cm-1, 3294.30 cm-1, 2989.75 cm-1, 1655.67 cm-1, 1553.79 cm-1, 1403.18 cm-1, 1051.56 cm-1, 829.64 cm-1. Concentration of chitosan 0.5 % (CS-0.5) resulted in the most significant at shelf-life extension with carrots, green tomatoes, tomatoes, cucumbers and beans showing increases of 12, 21, 21, 21, and 14 days, respectively, signifying the practical potential of chitosan-based edible coatings in vegetables preservation. Chitosan derived from Penaeus monodon has favorable characteristics for reducing vegetable's postharvest loss. Chitosan-based edible coatings improve food preservation and support sustainable practices, aiding in attaining 2, 3, 12, and 13 UN Sustainable Development Goals (SDGs)
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
