Adsorption Performance of Modified Nkalagu Bentonite in Dye Removal: Kinetics, Equilibrium, Thermodynamics and Structural Properties of the Modified Samples
Authors: Ajemba Regina Obiageli 
Published: June 2021

The adsorption performance of modified Nkalagu bentonite in removing Congo red (CR) from solution was investigated. The raw bentonite was modified by three different physicochemical methods: thermal activation (TA), acid activation (AA), and combined acid and thermal activation (ATA). The Congo red adsorption increased with increase in contact time, initial dye concentration, adsorbent dosage, temperature, and pH change. The results of the kinetics analysis of the adsorption data revealed that adsorption follows pseudo second-order kinetics. Analysis of the equilibrium data showed that Langmuir isotherm provided a better fit to the data. Evaluation of the thermodynamic parameters revealed that adsorption process is spontaneous and endothermic. The results from this study suggest that a combination of thermal and acid activation is an effective modification method to improve adsorption capacity of bentonite and makes the bentonite as low-cost adsorbent for removal of water pollutants.

Abstract
The preference reversal phenomenon occurs when revealed preference orderings for the same alternatives differ between 2 response modes. This phenomenon can be explained by dual process theories. System 1 is swift, automatic, and susceptible to biases, but System 2 is slow and deliberative and can correct biases produced by System 1. A more impulsive person, using fewer cognitive resources for System 2 to correct biases produced by System 1, should be more susceptible to decision biases (e.g., the preference reversal phenomenon). Research has revealed that rs806379, a single-nucleotide polymorphism of the cannabinoid receptor 1 gene, is linked to impulsivity: People with the A/A genotype are more impulsive than others. Therefore, we speculated that rs806379 polymorphism may affect the preference reversal phenomenon. In this study, healthy subjects chose between bets with high monetary amounts but low probabilities ($-bets) and bets with high probabilities but low monetary amounts (P-bets) and then evaluated them separately; they also provided saliva samples for genotyping. As expected, subjects exhibited a strong preference reversal phenomenon. Furthermore, subjects with the A/A genotype exhibited a stronger preference reversal phenomenon than others when the ratios of monetary amounts in $-bets to those in the P-bets were large. This is the first study to investigate the preference reversal phenomenon in terms of genetics. Our findings suggest that decision-making behaviors such as the preference reversal phenomenon can be influenced by a single gene locus variation in healthy human beings.

Authors: Feitoza Veronica Damasceno de Souza , Silva Simone Batista da 
Published: June 2021

O Decreto 5.154/04, que regulamenta a Educação Profissional Técnica de Nível Médio, é considerado um avanço em relação aos anteriores por permitir que a Educação Profissional Técnica seja ofertada na modalidade Integrada ao Ensino Médio sob a articulação dos eixos trabalho, ciência, tecnologia e cultura. Assim, possibilita que as práticas pedagógicas para essa modalidade de ensino superem os conhecimentos puramente técnicos e sejam encaminhadas com vistas à formação ampla dos sujeitos. Nesse sentido, as Orientações Curriculares para o Ensino Médio, na sessão Língua Estrangeira – OCEM-LE, (BRASIL, 2006), sugerem que as práticas de ensino de língua estrangeira sejam embasadas na teoria dos Letramentos Críticos buscando formar indivíduos criativos, críticos e de mente aberta para o exercício de cidadania plural. Assim, esta pesquisa investigou de que modos, ao serem balizadas na teoria dos Letramentos Críticos, as práticas docentes em aulas de Língua Inglesa do Curso Técnico em Agropecuária Integrado ao Ensino Médio podem contribuir para a formação integral dos alunos do Instituto Federal de Educação, Ciência e Tecnologia do Pará (IFPA) – Campus Castanhal. Os dados coletados provêm de observação participante e gravação de áudio das aulas de Língua Inglesa durante a execução de uma sequência didática elaborada para a pesquisa com base nesses princípios teóricos e utilizando textos multimodais. A investigação demonstrou que práticas pedagógicas direcionadas por princípios dos Letramentos Críticos podem contribuir com uma formação para além da instrumentação linguística e a preparação para o mercado de trabalho, pois estimulam os alunos a lerem a si mesmos e ao mundo criticamente.

Objective: The purpose of this article is to substantiate the psychological conditions that determine the content, forms, ways of organising, and promoting the process of socialisation of gifted students.
Background: The success of modern man largely depends on his socialisation – the ability to see and understand others, analyse the course of events, to capture the prospects for development. Therefore, the key competencies include, among others, information and communication and social as those that ensure the successful acquisition of knowledge throughout life and entry into society.
Method: A set of methods was used in the study: analysis, synthesis, generalisation, and systematisation of scientific data, observations, questionnaires, document analysis, methods of mathematical data processing. An online testing platform was developed to conduct a survey of students.
Results: The authors proposed and implemented a project aimed at providing psychological and pedagogical support to gifted students; to provide the teaching staff with the necessary knowledge and skills to work with gifted children, to encourage participants in the educational process to use information and communications technology tools in educational activities. A model of psychological support and accompaniment of participants in the educational process has been developed.
Conclusion: The experiment showed positive changes in socialisation in the experimental group in relation to the control group at a significant level. The findings of the study give grounds to conclude that the proposed author's comprehensive approach promotes the socialisation of gifted students.

Published: June 2021

Este trabajo presenta un análisis de la literatura científica sobre las consecuencias que tiene el uso que hacen los menores de las Tecnologías de la Información y la Comunicación (TIC). Para ello, se ha realizado una investigación de tipo teórica-bibliográfica, recurriendo a bases de datos de índole nacional e internacional, para obtener un total de 36 documentos que responden a los descriptores “familia” e “Internet” y a los criterios de inclusión-exclusión empleados, a partir de los cuales se han recogido riesgos y posibilidades para los menores de la red. Los datos han sido extraídos mediante una rejilla de vaciado de contenido, a partir de los cuales se concluye que, en los artículos analizados, los riesgos más generalizados son es el acceso al contenido nocivo, el ciberacoso y la adicción a la red, mientras que las posibilidades más destacadas que ofrece Internet son la creación de una identidad digital, el uso educativo de la red y las relaciones sociales que se pueden establecer a través de la misma. Finalmente, se lleva a cabo una propuesta de pautas educativas dirigidas a familias que permitan poner en práctica las posibilidades educativas y mitigar los principales riesgos de Internet que exponen las publicaciones estudiadas.
This paper presents an analysis of the scientific literature on the consequences of children's use of Information and Communication Technologies (ICT). For this purpose, a theoretical-bibliographic research has been carried out, using databases of national and international nature, to obtain a total of 36 documents that respond to the descriptors "family" and "Internet" and to the inclusion criteria- employee exclusion, from which risks and possibilities for minors in the network have been collected. The data has been extracted through a content dump grid, from which it is concluded that, in the articles analyzed, the most widespread risks are access to harmful content, cyberbullying and network addiction. However, the most important possibilities offered by the Internet are the creation of a digital identity, the educational use of the network and the social relationships that can be established through it. Finally, a proposal of educational guidelines aimed at families that allow implementing the educational possibilities and mitigate the main Internet risks that expose the publications studied is carried out.

Authors: Santa Medina Rebeca 
Published: June 2021

Este trabajo de investigación constituye un estudio de caso, con el que se pretende conocer las implicaciones para el profesorado que ha tenido que pasar de un modelo de enseñanza presencial a una modalidad de e-learning, a raíz de la pandemia del Covid-19, analizando el caso concreto del centro educativo de Primaria Buen Pastor.
Para ello, primero se expone un marco teórico para adentrarnos en el tema objeto de estudio, así como las variables que más tarde analizamos y, a continuación, se muestra la parte empírica, para la que se utilizó una muestra de 20 docentes de Educación Primaria, y se recabó información a través de cuestionarios; así como de entrevistas individuales.
Con todo, el estudio se centró en analizar aspectos como: las herramientas y recursos, así como las estrategias didácticas para el trabajo en red utilizadas por los docentes o su opinión sobre este cambio de modalidad presencial a modalidad online y su punto de vista acerca de ella tras este periodo. Los resultados fueron reveladores, lográndose los objetivos que se perseguían. Con ellos se puso de manifiesto la necesidad de mejorar la alfabetización y la competencia digital de los docentes a pesar de las innumerables herramientas y recursos existentes; el potencial educativo de esta modalidad de enseñanza y el enorme esfuerzo que han tenido que hacer los docentes para adaptarse a ella
This research is a case study, which aims to analyze the implications for teachers who have had to change the traditional classroom teaching to e-learning, due to the Covid-19 pandemic, analyzing the specific case of the school of Buen Pastor Primary.
To do this, firstly a theoretical framework is presented to go into the subject of the study, as well as the variables that we later analyzed, and then the empirical part is shown, for which a sample of 20 primary school teachers was taken and information was collected through surveys, as well as through individual interviews.
However, the study focused on analysing aspects such as: the tools and resources, as well as the didactic strategies for working in networks used by the teachers but also their opinion about this change from a face-to-face to an online mode and their point of view about it after this period. The results were revealing, achieving the objectives that were being pursued, and being able to analyze deeply the object of study. With them it was shown how inefficient were the teachers in terms of e-learning despite all the tolos and resources that they had, the high educative potential and the big effort that teachers had to make to adapt themselves to it.
Une ancienne traduction de La Nouvelle Astrée « ad usum delphini » ? La double lecture du texte
Authors: Doležalová Pavla 
Published: June 2021

Le grand cycle romanesque de Honoré d’Urfé L’Astrée, oeuvre majeure du genre pastoral en France, a connu d’innombrables adaptations. Une version abrégée intitulée La Nouvelle Astrée, anonyme ou attribuée à l’abbé de Choisy, a été publiée à Paris en 1712, pour être traduite en russe dès 1789. Si La Nouvelle Astrée n’a pas su transmettre le message complexe de son prestigieux modèle, miroir des aspirations de la noblesse, est-ce que la version russe de ce petit roman a pu en saisir le noyau et comment, à l’appui de quels choix traductologiques ? Notre expérience de sa première traduction en tchèque (parue en 2017) par la méthode de lecture herméneutique et une comparaison systématique du texte russe en cyrillique avec l’original français nous a permis de confirmer l’hypothèse du choix d’une stratégie traductologique spécifique. Le recours aux simplifications, aux explications et aux omissions des expressions considérées comme gênantes semble répondre à l’intention d’adapter le texte à des buts éducatifs, afin de le rendre plus accessible au public plus francophile que francophone. Les altérités en ce qui a trait aux signifiants et aux signifiés se voient atténuer sinon effacer, ce qui entraîne, dans les domaines notamment du lexique de la stylistique, d’importantes modifications.
Aigo ! Le casse-tête de la traduction littéraire d’interjections onomatopéiques coréennes
Authors: Jeanmaire Guillaume , Duval Arnaud 
Published: June 2021

Cette étude examine les différentes stratégies mises en oeuvre par les traducteurs pour rendre en français l’expressivité des interjections onomatopéiques coréennes. À la différence de l’onomatopée, une interjection est, en réaction à une situation vécue, pourvue d’un affect, d’une intention de communiquer (expressive ou injonctive). Entre manifestation émotionnelle et formulation implicite, leur ambiguïté sémantique ne permet pas d’en interpréter aisément la valeur situationnelle, telle qu’elle est communément interprétée dans la culture d’origine. À défaut d’interjections équivalentes en langue cible, les traducteurs des interjections coréennes ont donc alternativement recours soit à de simples translittérations, soit à des reformulations plus explicites non interjectives. Après avoir défini le cadre de notre étude, nous étudierons, par des exemples empruntés à la littérature coréenne, les différentes stratégies qui permettent de traduire et transmettre en français la valeur expressive et la charge émotive de ces éléments de langage dits « primaires ». Enfin, nous proposerons quelques solutions de rechange non interjectives ou somatiques pour rendre perceptible leur densité sémantique.
Bite force estimates in juvenileTyrannosaurus rexbased on simulated puncture marks
Authors: Peterson Joseph E. , Tseng Z. Jack , Brink Shannon 
Published: June 2021

BackgroundBite marks attributed to adultTyrannosaurus rexhave been subject to numerous studies. However, few bite marks attributed toT. rexhave been traced to juveniles, leaving considerable gaps in understanding ontogenetic changes in bite mechanics and force, and the paleoecological role of juvenile tyrannosaurs in the late Cretaceous.MethodsHere we present bite force estimates for a juvenileTyrannosaurus rexbased on mechanical tests designed to replicate bite marks previously attributed to aT. rexof approximately 13 years old. A maxillary tooth of the juvenileTyrannosaurusspecimen BMR P2002.4.1 was digitized, replicated in dental grade cobalt chromium alloy, and mounted to an electromechanical testing system. The tooth was then pressed into bovine long bones in various locations with differing cortical bone thicknesses at varying speeds for a total of 17 trials. Forces required to replicate punctures were recorded and puncture dimensions were measured.ResultsOur experimentally derived linear models suggest bite forces up to 5,641.19 N from cortical bone thickness estimated from puncture marks on anEdmontosaurusand a juvenileTyrannosaurus. These findings are slightly higher than previously estimated bite forces for a juvenileTyrannosaurus rexof approximately the same size as BMR P2002.4.1 but fall within the expected range when compared to estimates of adultT. rex.DiscussionThe results of this study offer further insight into the role of juvenile tyrannosaurs in late Cretaceous ecosystems. Furthermore, we discuss the implications for feeding mechanisms, feeding behaviors, and ontogenetic niche partitioning.
Dynamic residue interaction network analysis of the oseltamivir binding site of N1 neuraminidase and its H274Y mutation site conferring drug resistance in influenza A virus
Authors: Yadav Mohini , Igarashi Manabu , Yamamoto Norifumi 
Published: June 2021

Background
Oseltamivir (OTV)-resistant influenza virus exhibits His-to-Tyr mutation at residue 274 (H274Y) in N1 neuraminidase (NA). However, the molecular mechanisms by which the H274Y mutation in NA reduces its binding affinity to OTV have not been fully elucidated.

Methods
In this study, we used dynamic residue interaction network (dRIN) analysis based on molecular dynamics simulation to investigate the correlation between the OTV binding site of NA and its H274Y mutation site.

Results
dRIN analysis revealed that the OTV binding site and H274Y mutation site of NA interact via the three interface residues connecting them. H274Y mutation significantly enhanced the interaction between residue 274 and the three interface residues in NA, thereby significantly decreasing the interaction between OTV and its surrounding loop 150 residues. Thus, we concluded that such changes in residue interactions could reduce the binding affinity of OTV to NA, resulting in drug resistant influenza viruses. Using dRIN analysis, we succeeded in understanding the characteristic changes in residue interactions due to H274Y mutation, which can elucidate the molecular mechanism of reduction in OTV binding affinity to influenza NA. Finally, the dRIN analysis used in this study can be widely applied to various systems such as individual proteins, protein-ligand complexes, and protein-protein complexes, to characterize the dynamic aspects of the interactions.

Copper is an essential trace mineral (micronutrient) that is naturally present in some foods and is available as a dietary supplement. Pregnancy, also known as gestation, is the time during which one or more offspring develops inside a woman.This study was desiged to assay the copper level of pregnant women in urban area and to evaluate the effect of the obtained valves on some blood parameters of the pregnant women. In this study, a total of 100 subjects and 50 controls was used. subjects were pregnant women while the controls were non-pregnant women. The copper level in subject was assayed with a serum copper test kit using automation with Bio E-lab fully automated chemistry analyzer and result of the complete blood count was gotten using Mindray Hematology analyzer. The mean for subjects (M=102.83±1.38) and control (M=102.68±0.94), p = 0.71. These results suggest that the difference between the copper level for subjects and controls is not really much.. The variables copper level and MCV were found to be slightly correlated, r(150) = ..018., p > .005. Additionally, copper levels in the subjects was also found to negatively correlated with MCH, r(150) = .907, p > .005. One-way analysis of variance showed that the correlation of copper levels was not significant on all of the red bloodcell parameters in the serum of the pregnant women.
Nanoporous Morphogenesis in Amorphous Carbon Layers: Experiments and Modeling on Energetic Ion Induced Self‐Organization
Authors: Hoffmann Daniel T. , Dietrich Johannes , Mändl Stephan , Zink Mareike , Mayr Stefan G. 
Published: June 2021

AbstractNanoporous amorphous carbon constitutes a highly relevant material for a multitude of applications ranging from energy to environmental and biomedical systems. In the present work, it is demonstrated experimentally how energetic ions can be utilized to tailor porosity of thin sputter deposited amorphous carbon films. The physical mechanisms underlying self‐organized nanoporous morphogenesis are unraveled by employing extensive molecular dynamics and phase field models across different length scales. It is demonstrated that pore formation is a defect induced phenomenon, in which vacancies cluster in a spinodal decomposition type of self‐organization process, while interstitials are absorbed by the amorphous matrix, leading to additional volume increase and radiation induced viscous flow. The proposed modeling framework is capable to reproduce and predict the experimental observations from first principles and thus opens the venue for computer assisted design of nanoporous frameworks.
