Cord Blood-Based Approach to Assess Candidate Vaccine Adjuvants Designed for Neonates and Infants
Authors: Tokuhara Daisuke , Hikita Norikatsu
Published: January 2021

Neonates and infants are particularly susceptible to infections, for which outcomes tend to be severe. Vaccination is a key strategy for preventing infectious diseases, but the protective immunity achieved through vaccination typically is weaker in infants than in healthy adults. One possible explanation for the poor acquisition of vaccine-induced immunity in infants is that their innate immune response, represented by toll-like receptors, is immature. The current system for developing pediatric vaccines relies on the confirmation of their safety and effectiveness in studies involving the use of mature animals or adult humans. However, creating vaccines for neonates and infants requires an understanding of their uniquely immature innate immunity. Here we review current knowledge regarding the innate immune system of neonates and infants and challenges in developing vaccine adjuvants for those children through analyses of cord blood.
Spatial-Temporal Change of Actual Evapotranspiration and the Causes Based on the Advection–Aridity Model in the Weihe River Basin, China
Authors: Xu Ruirui , Gao Peng , Mu Xingmin , Gu Chaojun
Published: January 2021

Evapotranspiration is a key process between the atmospheric hydrological cycle and the energy cycle, which has a great significance in understanding climate change and the rational use of water resources, especially for the Weihe River basin (WRB) (a basin in China experiencing a shortage of water resources). We investigated the spatial-temporal change of actual evapotranspiration (ETa) based on the daily meteorological variables of 22 meteorological stations and the annual streamflow of three hydrological stations from 1970 to 2018 in the WRB. The contributions of key meteorological variables to ETa changes and the sensitivity coefficient are also quantified. The temporal trends of ETa showed an increasing trend from 1970 to 2018, and the spatial distribution of ETa increased from northwest to southeast in the WRB. Increasing trends were detected in the multi-year average, spring, and winter, but only a few stations passed the significance test. Summer and autumn showed a decreasing trend, but this trend was not significant. Solar radiation is the most sensitive meteorological variable, followed by vapor pressure, wind speed, and mean temperature. Vapor pressure contributes the most to ETa changes, followed by solar radiation. In general, vapor pressure (relative humidity) is the dominant meteorological factor affecting ETa in the WRB. In addition to meteorological factors, the ETa is also affected by combined and complicated factors caused by precipitation and human activities. As an important part of the hydrological cycle, ETa has important research significance for water resources management, economy, agriculture, and ecology and results of this study may be helpful to further clarify the climate change and human activities impacts on the basin hydrological cycle.
Sustainability Assessment of White Shrimp (Penaeus vannamei) Production in Super-Intensive System in the Municipality of San Blas, Nayarit, Mexico

Published: January 2021

The super-intensive white shrimp system is more productive (t ha−1) than traditional systems. However, it implies greater investment in infrastructure and machinery, a continuous supply of electricity, and a specialized workforce. Therefore, the sustainability of a shrimp farm model operating in a super-intensive system in Nayarit (Mexico) was evaluated using financial analysis and life cycle assessment. The investment is important, but the fixed costs (16%) are much lower than variable costs (84%). The super-intensive farm is economically viable, with an overall profitability (29%) that is higher than that of other agri-food activities in Mexico. It is also an activity that generates a lot of employment, in relative terms, as well as economic movement in the area. The potential environmental impacts are higher than those registered in semi-intensive shrimp systems but slightly lower than those registered in intensive systems. The estimated global warming value per kg of shrimp is 5.08 kg CO2-eq, an intermediate value. Also, as the shrimp production is much higher than in traditional systems, it could have a great and positive impact on the maintenance and regeneration of the mangrove ecosystem.
Blue Water Visitor Monitoring Potential: A Literature Review and Alternative Proposal
Authors: Andrew Ross , Burns Robert , Schwarzmann Danielle , Allen Mary , Moreira Jasmine
Published: January 2021

This review presents a summary of existing visitor monitoring methods and relevant studies in land and marine-based areas, with a focus on the application to unique aquatic settings. Various opportunities and challenges exist with respect to the use of each method in different marine settings. These methods differ in terms of the complexity, costs, level of accuracy, and detailed information they provide. Furthermore, the feasibility of applying these methods also depends on the site attributes of a marine area. Since each marine area varies in geographical scale and environmental and social conditions, some methods will be more appropriate or perform more successfully than others in a particular location. Therefore, the consideration of these methods should be part of a proposed alternative process, focused on adaptive monitoring that scales to address visitor ebbs and flows in these aquatic areas. The proposed alternative seeks to develop consensus around quantitative goals for visitor monitoring and estimating techniques in marine settings, using a customizable mix of methods and techniques. This alternative effort progresses to subsequent tasks and discussions, and recommendations are made considering the feasibility and confidence of using these methods in particular marine settings and future pilot sites.
The Significance of Vertical and Lateral Groundwater–Surface Water Exchange Fluxes in Riverbeds and Riverbanks: Comparing 1D Analytical Flux Estimates with 3D Groundwater Modelling
Authors: Ghysels Gert , Anibas Christian , Awol Henock , Tolche Abebe , Schneidewind Uwe , Huysmans Marijke
Published: January 2021

Riverbed temperature profiles are frequently used to estimate vertical river–aquifer exchange fluxes. Often in this approach, strictly vertical flow is assumed. However, riverbeds are heterogeneous structures often characterised by complex flow fields, possibly violating this assumption. We characterise the meter-scale variability of river–aquifer interaction at two sections of the Aa River, Belgium, and compare vertical flux estimates obtained with a 1D analytical solution to the heat transport equation with fluxes simulated with a 3D groundwater model (MODFLOW) using spatially distributed fields of riverbed hydraulic conductivity. Based on 115 point-in-time riverbed temperature profiles, vertical flux estimates that are obtained with the 1D solution are found to be higher near the banks than in the center of the river. The total exchange flux estimated with the 3D groundwater model is around twice as high as the estimate based on the 1D solution, while vertical flux estimates from both methods are within a 10% margin. This is due to an important contribution of non-vertical flows, especially through the riverbanks. Quasi-vertical flow is only found near the center of the river. This quantitative underestimation should be considered when interpreting exchange fluxes based on 1D solutions. More research is necessary to assess conditions for which using a 1D analytical approach is justified to more accurately characterise river–aquifer exchange fluxes.
Impacts of Irrigation Water on the Hydrodynamics and Saline Behavior of the Shallow Alluvial Aquifer in the Senegal River Delta

Published: January 2021

The Senegal River Delta located in north-western Senegal is a strategic region for the development of irrigated rice cultivation for achieving rice self-sufficiency. The presence of a shallow salty water table is often considered as a brake to the development of irrigation, by causing salinization of the soil, although the mechanisms of operation are not well known. An experimental study was carried out in a rice paddy located in the village of Ndiaye, 35 km north from Saint Louis, to characterize the water and solute flux processes below the irrigated plots. The objective was to better understand the irrigation-driven dynamics of soil salinization processes. An experimental monitoring network was installed for monitoring the transit of water at the plot level, in the unsaturated zone and in the aquifer. The results show that the supply of water by irrigation contributes to significantly recharging the water table, as shown by the rise in piezometric level, with a concomitant dilution of the water salinity in the soil zone and in the shallow groundwater. However, when irrigation is stopped, the groundwater level and salinity return within a month to their initial level and salinity status because of the evaporative recovery, which strongly governs these processes. Thus, water flow and solute transfers operate in the delta following a recharge–discharge and dilution–concentration cycle controlled by the water balance, and we do not expect to observe in the short- to middle-term any significant reduction in soil salinization processes by drainage.

„Radikal“ Newspaper Publishing Company
Authors: Panayotov Todor
Published: January 2021

The study examines the newspaper company „Radikal“, which is founded in 1914 and declares bankruptcy in 1939 in the wake of WWII and the major transitions in Bulgaria during that time. The company’s final end comes in 1953. There are no studies in the journalistic literature that examine „Radikal“ in detail, so this study aims to fill this gap by tracing and evaluating the company’s activities. The study uses a chronological approach and content analysis and is based on archival sources that have not been previously used in the scientific literature, as well as on newspaper sources and other references from the journalistic and historic literature. The study concludes that „Radikal“ presents a good example of a successful party-associated newspaper publishingcompany, which is why it left a significant mark on the newspaper industry in the history of the Bulgarian Kingdom.

Determination of antimicrobial and anti-quorum sensing activities of water and ethanol extracts of propolis
Authors: SORUCU Ali , CEYLAN Özgür
Published: January 2021

Quorum Sensing is a special system between bacteria to communicate with the signal molecules. Propolis is a resin collected from plants by honey bees. The present study examined anti-quorum sensing and antimicrobial activities of water and ethanol extracts of propolis. The antimicrobial activities of the propolis extracts were studied against Escherichia coli ATCC 25922 Gram (-), Listeria monocytogenes ATCC 7644, Streptococcus mutans CNCTC 8/77, Staphylococcus aureus ATCC 25923 Gram (+), Candida albicans ATCC 10239 (yeast) by the well diffusion method. Anti-quorum sensing activity, violacein inhibition activity, and anti-swarming activity were studied using Chromobacterium violaceum CV026 and C. violaceum ATCC 112472, and Pseudomonas aeruginosa (PA01) respectively. Both propolis extracts were detected antibacterial activity against Gram (+) bacteria and Candida albicans. However, antibacterial activity against Gram (-) bacteria were not observed. While the antimicrobial activity of water extract propolis was determined more effectively than ethanol extract, anti-quorum sensing and anti-swarming activities less effective. It was also detected that both extracts display violacein inhibition. It was revealed that the antimicrobial, anti-quorum sensing, anti-swarming activity depended on the dose of propolis extracts. Thirty-six phenolic compounds were analysed of propolis extract by HPLC-DAD. The amount and presence of phenolic compounds in the ethanol extract were more than the water extract apart from benzoic acid, cinnamic acid, syringic acid, (±) epigallocatechin, vitexin, rutin, and trans-chalcone. Consequently, the study put forward that the phenolic compounds of propolis have antibacterial, anti- quorum sensing, violacein inhibition, and anti-swarming activities changing depend on directly the extraction solvent and phenolic compounds.

En el presente trabajo se abordan, en primer lugar, las líneas maestras que sustentan la concepción de la historia de la literatura occidental que subyacen a la teoría literaria de Northrop Frye. En este sentido, se ha tenido en cuenta la influencia decisiva que la interpretación tipológica de la Biblia tiene en la configuración de esa concepción histórica, lo que ha llevado a Frye a afirmar que las Escrituras constituyen un modelo para la lectura y estudio de la literatura. Por otro lado, proponemos acercarnos a la escritura crítica de Frye desde la perspectiva que nos ofrece la Retórica Cultural propuesta por Tomás Albaladejo. Consideramos que la perspectiva retórico-cultural nos permite llevar a cabo una fructífera relectura de su concepción de la crítica literaria como “a science as well as an art”. Por último, nos hemos ocupado del dispositivo retórico de la metáfora y de su inscripción en la crítica literaria de Northrop Frye, atendiendo a la noción de motor metafórico propuesta, igualmente, por Tomás Albaladejo.

Women of the other Epics in view of Periyar
Authors: P Kamalakannan
Published: January 2021

As English has its influence throughout the world, most of Shakespeare’s works became famous. Even then, one can challenge that so far no one has written anything which can beat down the classical epics and Idhikāsams. There is no much difference between men and women in nature. Both are similar in aesthetics, knowledge, character etc. The respect given to women during Sangam period has got changed. They were refused of their rights in the later literature and in the minds of the poets. The chaste women in the Tamil epics were obedient to their husbands, and on one would have ever questioned their husbands. Akalyai, who accidently lost her chastity is also included in the list of chaste women. Panchali, who is referred as Draupathi, Krishnai, Indhirasenai, Thrihayani is the heroine of Vyasar’s Maha Bharatham, won by Arjuna in Swayamvaram, she became wife of five Pandavas on the words of Kunthi. She appealed to Kannan to safeguard her during the abuse happened to her by Dushyasana, in Dhruyodhana’s court when the game of dice was challenged to her husband. Sita, the heroine of Ramayana is adored as the ‘fire of chastity’, ‘ornament of chastity’ etc. Though Mandodhri condemns her husband’s activities, she is also added to be one among the chaste women as she died immediately following her husband’s death. Periyar appreciates only certain heroine who parallels his ideologies of reasoning, discipline and self-respect and criticizes others.

Ensino remoto de língua francesa, por meio da canção, para idosos: desafios e perspectivas
Authors: Dantas de Medeiros Sandra Helena Gurgel , Soares Bernardo Luiz Antunes , Santos Deise Leite
Published: January 2021

Pesquisas mostram que grande parte dos idosos é motivada a aprender língua estrangeira (LE), sobretudo, para voltarem a ser produtivos, ter um envelhecimento ativo e pela questão da socialização. No entanto, como sabemos, com o advento da pandemia do novo coronavírus, medidas de restrição do convívio social foram tomadas para evitar a propagação da doença, principalmente de pessoas idosas pertencentes a grupos de risco. Consequentemente, a pandemia potencializou a solidão e tem dificultado qualquer projeto de participação em cursos de línguas de forma presencial. Nessa perspectiva, o presente trabalho tem como objetivo relatar a experiência vivenciada durante a ministração de aulas remotas, vinculadas ao Projeto de Extensão da Universidade Federal da Paraíba “Chante & découvre: língua francesa, por meio da canção”, voltado para maiores de 60 anos. Conscientes de que a escolha do material didático-pedagógico deve estar relacionada às necessidades específicas desse público-alvo, stabelecemos a canção como material didático não somente para despertar-lhes o interesse em aspectos linguísticos e culturais franceses, mas também para tentar atenuar as incertezas e a solidão no contexto da pandemia. Neste trabalho, primeiramente discutimos sobre teorias que fundamentam o processo de ensino-aprendizagem, principalmente na terceira idade. Em seguida, contextualizaremos o curso, seus objetivos, metodologia, gêneros musicais adotados, os perfis socioculturais dos participantes, entre outros. Finalmente, elencamos os objetivos traçados e os resultados alcançados a fim de refletir sobre as dificuldades e as soluções encontradas, bem como identificar os elementos que contribuíram para redinamizar o ofício de professor de línguas, no nosso caso específico, de língua francesa.
A escrita criativa das histórias de vida na formação de professores(as) de francês língua estrangeira
Authors: Costa Wellington Júnio
Published: January 2021

L’écriture créative a souvent peu d’espace dans le cursus de Lettres au Brésil, bien qu’il s’agisse d’une activité qui favorise le développement de l’écrit par une approche littéraire en même temps que celui de la réflexion sur le processus de formation d’enseignant.e. De 2016 à 2019, nous avons animé, à l’Université Fédérale de Sergipe, des ateliers d’écriture créative auprès des étudiant.e.s en Licence de Lettres Portugais-Français. Avec des objectifs précis établis en amont, soit la participation à des concours littéraires, soit la confection artisanale d’une plaquette bilingue, leurs productions (des poèmes ou des récits courts) se sont montrées comme une expression privilégiée de leurs personnalités, de leurs identités voire de leurs histoires de vie. Cet article a donc pour but de présenter les procédés  pédagogiques de ces ateliers, ainsi que quelques réflexions appuyées sur les définitions de l’écrivain de Jean-Paul Sartre (1986), sur les principes pédagogiques de Luiz Antonio de Assis Brasil (2018) et sur les études de Jean-Pierre Cuq et Isabelle Gruca (2018) à propos de la didactique de la production écrite.

Neste artigo, temos por objetivo trazer contribuições de ordem teórica e metodológica à coleta de dados, considerada a principal ação para o professor envolvido na preparação de programas de ensino do francês para contextos específicos, profissionais e acadêmicos. Em seguida, apresentaremos as ações didático-metodológicas adotadas no âmbito da oficina Mobilidade acadêmica para Letras nas universidades francesas: iniciação à redação do commentaire composé e da explication de texte. Para refletir sobre essas ações e aplicá-las, apoiamo-nos nos trabalhos de Mangiante e Parpette (2004; 2011; 2018) na área do Francês para objetivo específico (FOS) e em sua declinação, o Francês para objetivo universitário (FOU). A referida oficina se enquadra no cenário atual de investimentos na mobilidade acadêmica do aluno de Letras da Universidade de São Paulo (USP) em universidades francesas e da consequente oferta de oficinas e cursos de preparação linguística e cultural para esse público pelo Centro Interdepartamental de Línguas da Faculdade de Filosofia Letras e Ciências Humanas da USP (CIL-FFLCH-USP).
Les contradictions des politiques linguistiques brésiliennes et leurs enjeux pour une formation plurilingue et relativiste
Authors: Azevedo Andreia Matias
Published: January 2021

Cette étude vise à soulever une réflexion sur les politiques linguistiques brésiliennes concernant l’enseignement et l’apprentissage des langues étrangères au cours de l’histoire afin de démontrer que les actions du gouvernement brésilien vont à contre-courant des demandes du contexte politique, économique et social, favorisant ainsi la marche en arrière du pays. D’emblée, cette affirmation part de la nouvelle Base NationaleCommune Curriculaire Brésilienne (BNCC) dans laquelle on remarque que l’anglais est la seule langue étrangère enseignée. Il ne reste aucun doute que l’anglais joue en rôle important dans l’actuel scénario ; pourtant, il serait judicieux également que le système éducatif offre d’autres langues de sorte que les apprenants puissent visionner le monde de différentes perspectives et, par conséquent, développent un sentiment d’altérité, et un regard critique sur l’Autre et Soi-même (LEVINAS, 2014; CARLO, 1998). Un autre point à remarquer touche  le développement du pays dans la mesure où cette politique monolinguiste se montre nocive au projet d’internationalisation du système universitaire brésilien.
La formation des professeurs de français : un défi de taille pour la vie associative
Authors: Spita Doina , Pagel Dario , Eid Cynthia-Yaoute
Published: January 2021

Cet article portera sur la place de la vie associative dans la formation de professeurs de français qui se développe dans une logique de réseau. Il est essentiel de rappeler que si l’on veut que la langue française demeure une grande langue vivante internationale, il faut obligatoirement qu’elle conserve son prestige et cela passe nécessairement aujourd’hui par sa promotion dans la diversité institutionnelle et la cohérence pédagogique et didactique dans le contexte interculturel de la francophonie. De plus, ces formations visent à animer la vie associative, au travers d'un espace de rencontre et partage d'expériences entre les membres, ce qui sert également de motivation à un engagement plus important. De ce fait, nous exposons, dans les lignes qui suivent, les actions entreprises par la Fédération internationale des professeurs de français en tant qu’un lien capable de favoriser des échanges entre les enseignants liés au réseau, ainsi que la formation de ses membres associés, mettant en relief la place de la francophonie dans le monde.
De l’imitation à la création en langue étrangère: pouvoir être un autre
Authors: Pietraroia Cristina Casadei
Published: January 2021

Cet article aborde le passage obligatoire, dans l’apprentissage d’une langue étrangère, par le plaisir, le jeu, l’imitation et la création. Le contexte est celui de l’enseignement du français langue étrangère au niveau de la Licence dans une université brésilienne où les étudiants, dont la plupart sont débutants, doivent non seulement apprendre cette langue mais aussi en faire un objet de travail. Il faut donc qu’ils la maîtrisent bien et, pour cela, ils doivent être préparés à mettre en question leurs propres identités et à se montrer dans ce qu’ils ont de plus subjectif : leurs souvenirs et leurs émotions.

Observed the mastery of practical skills, as competencies for compiling OSСE (Objective structured clinical examination), by 6th year students and interns of various specialties in Odessa national medical university (Ukraine). Practical skills were performed on realistic simulation mannequins. The difference in outcomes was based on different learning conditions during the period of changing quarantine restrictions due to the COVID-19 pandemic in The Whole World. The results of observations were evaluated by the following parameters: time spent performing practical skills (in seconds) and the score (in marks) obtained by checklist. The final results testified a crucial part of the offline mode in mastering practical skills as competencies for compiling an Objective structured clinical examination, and the possibility of organizing theoretical learning processes in the online-form with obtaining certain positive results.
