Bangladesh Agriculture Research lnsutute, Joydebpur. Gazipur and cold storage
of Bangladesh \gncultur::il Development Corporation. Airport. Dhaka dunng the
period from April 14 to June 15, 2005. The objectives of the experiment were to
evaluate the effects of temperature, packaging methods and ethylene on quality of
banana during storage. Two experiments were conducted: first effect of packaging
methods and temperature on the shelf life of banana. There were ten treatment
combinations comprising two levels of temperature i.e room temperature (28-
J00C). low temperature ( 14-15°() and five packaging methods viz. control,
banavac, banavac with ethylene absorbent [Kivt:n04], perforated polythene and
non-perforated polybags. Second experiment effect of ethylene and type of
banana on ripening fruits. There were two types of banana viz. fresh banana and
stored banana and four dosages of ethylene such as 0 (Control), 250 ppm, 500
ppm and 750 ppm.
In the first experiment, weight loss (7.99%) was lower at low temperature than
that of room temperature irrespective of packaging methods. Banavac and
banav ac with KMnOJ packages at low temperature (14-15°C) was the best
method for lengthening shelf life of green banana. Banana also kept fresh, green
and hard for 21 days at both room temperature (28-30°C) and low temperature
(I 4- I 5°C) in banavac and banavac with KMnOJ packages.
In the second experiment. reducing sugar (9.20%), non-reducing sugar (6.10%),
total sugar ( 15.30° o). P11 ( 5.3 l ) and TSS (25. l 0%) of stored fruit were higher than
that of fresh banana. Total acid content (0.31 %) of stored banana was IO\\ er that
or fresh banana (0.36° o)
Thermal properties of tricalcium aluminate: Molecular dynamics simulation and experimental approach
No full textResearch conducted in the framework of MIRACLE Project (Photonic Metaconcrete with Infrared RAdiative Cooling capacity for Large Energy savings, GA 964450), coordinated by Dr. Jorge Sánchez Dolado, from Centro de Física de Materiales (CFM).The energy sector is making a noticeable effort to migrate towards renewable energy to tackle the global warming effect. At large scale, a concentrated solar plant (CSP) is one of the viable options with limitations of steady heat generation due to the uncertainty of sunlight. Thermal batteries can mitigate the trouble to a large extent. Recently, concrete (artificial rock glued by cement) has become a point of interest for the research community as a cheap, nontoxic option. In this paper, thermo-mechanical properties of tricalcium aluminate (C3
A) have been studied for the first time in the framework of molecular dynamics along with modulated differential scanning calorimetry (MDSC) based experiments. The outcome suggests high-temperature stability of the material with reasonably higher heat capacity and thermal conductivity useful for potential application for thermal battery. Heat transport mechanism at the atomistic level has thoroughly been discussed.This work was born under the umbrella of the project “Photonic Metaconcrete with Infrared RAdiative Cooling Capacity for Large Energy Savings (MIRACLE)” funded by the EU (GA 964450). This research was also carried out under the umbrella of the project PoroPCM (PCI2019-103657) funded by MCIN/AEI/10.13039/ 501100011033 and co-founded by the European Union (Programaci’on Conjunta Internacional 2019) and the projects MIRACLE (GA 964450) and NRG-STORAGE (GA 870114) funded by the European Commission, .

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
