Two new species of Pavanelliella (Dactylogyridae) were described and some details about the morphology of Pavanelliella pavanellii Kritsky & Boeger, 1998 were added based on specimens collected from pimelodid fishes from Mogi Guaçu River, Brazil. Pavanelliella takemotoi sp. n., collected from nasal cavities of Pimelodus maculatus Lacepède, 1803 differs from its congeners by having a male copulatory organ (MCO) with 2–5 rings, vaginal canal sinuous without loops in distal portion of vaginal canal and anteriorly directed vagina containing five irregular rings around the vestibule. Pavanelliella laertei sp. n. collected from P. heraldoi Azpelicueta, 2001 is separated from the other species of the genus by lacking a vaginal vestibule and by distal end shape of accessory piece, which resemble flames or is bifurcated with one flank hooked in P. laertei sp. n. The specimens of P. pavane...

The present experiment was conducted to evaluate the productive performance, egg quality and behavioral patterns of Japanese quails (Coturnix coturnix japonica) with and without beak trimming submitted to two stocking densities. The study was conducted for 84 days. In total, 196 Japanese quails were randomly allocated to a 2 x 2 factorial scheme: submitted or not to beak trimming procedure and low (237.5 cm²/bird) and high stocking density (316.7 cm/bird) and its interaction. Eight replicates per treatment were used, totaling 32 experimental units. Collected data were submitted to analysis of variance and, means of parametric data were compared by Tukey test (p<0.05); otherwise non-parametric analysis of variance were applied for non-parametric data of quail behavior. Lower feed intake was observed in the high stocking density group (p<0.05) but did not affect other parameters (p&...

Educommunication is a way of educative communication that promotes group learning from, trough and for communication. This paper systematizes two educommunicative experiences dealing with environmental issues, implemented by the Faculty of Communication of the University of Havana, in a collaboration project with the Cuban Environment Agency. As a result, it describes the methodological perspectives used, and the characteristics of the lived process emphasizing the roll of video and the learned lessons. It also highlights the importance of educommunication for integrating teenage population into environment management process.

This research focuses on the study of the native digital medium «La Posta» and its treatment of information. The objective is to analyze the application and adherence to ethical principles in journalism through a comprehensive review of its news articles. The methodological approach employed is content analysis, with a descriptive perspective; therefore, 31 informative journalistic articles from the «elTop» section, published on the official Instagram account of the medium in January 2023, were examined. The results of the analysis show that the medium does not conform to the ethical regulations of the Organic Law Reforming the Organic Communication Law (2019) of Ecuador. The news articles also do not adhere to the fundamental ethical principles of journalism. Additionally, the significance of advertising in the way the medium approaches information is highlighted. The absence of aut...

This article is born from a project linked to the research line Educational Practices, Culture, Diversity and Inclusion, carried out by the Pro-Rectory of  Research and Postgraduate Studies (PROPEG) of the State University of Rio Grande do Norte (UERN / BRAZIL). The aim of this study is to understand how the success of a UERN undergraduate student at the popular level and with poor vision has contributed to his social progress from Basic Education to Higher Education. It is a qualitative research, based on Oral History, from (auto)biographical narratives, which allow a formative and self-formative process in the writing of the self and of the other. The access and permanence of the student in his trajectory between Basic Education and the University is a result of the help of the family and the support of the Directorate of Policies and Inclusive Actions (DAIN) of UERN.

Propone la planificación hidráulica de la red de abastecimiento de agua potable de la ciudad de Barquisimeto tomando en cuenta la incorporación de las futuras fuentes, o bien incorporando mas caudal a través de las fuentes existentes, para ello se realizó un exhaustivo análisis de demandas de usuarios discretizado en residenciales, comerciales, industriales y oficiales, el cual permitió determinar la demanda actual y futura de la ciudad, estableciéndose así un concepto previo de la evolución del sistema basada en ofertas y demandas a corto, mediano y largo plazo, ayudando a la definición preliminar de las aducciones que se encargarán de incorporar estas futuras fuentes. Seguidamente, se desarrolló un modelo hidráulico de la red de Barquisimeto, donde se simularon las distintas opciones de trabajo de las aducciones que traerán los gastos de las fuentes antes mencionadas, tr...

Football clubs are traditional institutions with the particularity of having the main characters of their successes as intangible assets, that is, their players. The aim of this work is to analyse the determinants of the market values using intellectual and structural capital indicators as explanatory variables. Descriptive statistics and panel data model estimates were used in the analyses to control the footballers’ fixed effects, the club's fixed effects and the effects of player-year and club-year interactions. Results confirmed that footballers’ market value is determined by a set of variables that can be explained by components of human capital (one’s skills), structural capital (infrastructure that supports human capital). Understanding the players’ pricing can help both clubs and players to improve their management and increase the possibility of financial success.

This work is directed to Information and Communication Technology in Education. Virtual environments are used as spaces of speech in a social, political and economic context. The potential of these environments is undeniable, and they have become a wide-ranging place for research and interaction. This research, which is qualitative in nature and has an analytical-descriptive format, aims to explore ethnographic spaces online, through digital social networks, discussing, according to Habermasian assumptions of the public sphere, the potential of so-called "digital influencers" to contribute to science education and the dissemination of fake news on scientific topics. In methodological terms, the study is characterized as ethnography, more specifically a netnography on social networks, preceded by a survey, via questionnaires and interviews, with primary and secondary school students of th...

The research was carried out at the Molecular Immunology Center (CIM), a Cuban biotechnological institution dedicated to basic research, development, and manufacture of products for the treatment of cancer and other autoimmune diseases. The research problem addressed the poor management of inventories in companies, which is largely a consequence of the lack of procedures that enable the good performance of the logistics process. The objective of the research was the implementation of the inventory management procedure aimed at planning, managing, and controlling the necessary inventories without affecting the quality of the services, based on the analysis of indicators, description of logistics flows, and application of the Inventory Reference Model (MRInv). Different techniques and tools—including interviews, direct observation, surveys, documentary analysis, Minitab statistical softw...
