    Physicochemical properties and structural characteristics of whole rice flours with different treatments (soaking, germination and extrusion cooking) were studied. Water solubility, water absorption, crystallinity, adsorption isotherms (BET and GAB models), and glass transition temperature of the samples were determined. Water solubility and water absorption were enhanced by extrusion cooking process (3.17-4.98 vs. 24.1-53.76 g/100 g and 2.77-3.05 vs. 4.46-7.04 ml/g, respectively), but crystallinity was decreased (30-33 vs. 4-16%). Adsorption isotherms showed that extruded samples exhibited higher equilibrium moisture content as compared with their corresponding non-extruded samples (5.0-19.2 vs. 4.0-16.1 g water/g solids). There were no changes in glass transition temperature values in the studied moisture range (3.8-16 g/100 g). These results allow the correct use of whole rice flours with different treatments in foods and also contributed to the knowledge of stabilization of the products.Fil: Albarracín, Micaela.

    Going Beyond Counting First Authors in Author Co-citation Analysis

    Full text link
    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

    Full text link
    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

    La cultura del reciclaje alimentario llevada al hogar: de la mesa a la mesa

    [ES] El desperdicio alimentario no sólo es un problema medioambiental, sino que juega en contra del enorme problema al que se enfrenta la sociedad actual de paliar el hambre en el mundo. Muchos de los alimentos o partes de ellos que no se consumen, tienen un gran valor nutritivo y contienen muchos compuestos potencialmente beneficiosos para la salud, los llamados compuestos bioactivos entre los que se encuentran la fibra dietética, vitamina C, fenoles, carotenoides o clorofilas, entre otros. En este estudio se recoge el interés de convertir la piel de la naranja o la vaina del haba en un ingrediente alimentario en polvo, con un contenido en fibra, referida al total de solutos que contiene, del orden del 95 %, además de ser fuente del resto de compuestos bioactivos. Además, se propone la forma casera de obtenerlo y posibles usos del mismo.Proyecto PID2022-139711OB-C21 financiado por MCIN/ AEI /10.13039/501100011033/ y por FEDER Una manera de hacer Europa.Martínez-Navarrete, Nuria;Camacho Vidal, Mª Mar;García Martínez, Eva María (2025).

    Development of dried functional foods: Stabilization of orange pulp powder by addition of biopolymers

    The production of powdered food is an increasingly industry due to the high stability and easy handling of those products. The aim of this work was to evaluate the effect of the addition of gum Arabic (GA) in combination with bamboo fiber (BF) or cactus cladode mucilage (CM) on the physicochemical and antioxidant properties of orange pulp powder obtained by freeze drying. Additionally, the stability of the powders after 10 months of storage at 20 °C was evaluated. The results showed that the inclusion of GA with BF or CM to the orange puree previous to freeze drying improved their chemical and physical stability. The addition of solutes increased the glass transition temperature and made the samples more stable, without problems of collapse or caking during the storage. Functionally, the combination GA-BF resulted a better option since this formulation maintained better its antioxidant and antiradical properties over time.Fil: Pacheco, Consuelo.

    Dispelling the Myths Behind First-author Citation Counts

    Full text link
    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

    No full text
    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
