Nghiên cứu này bước đầu đánh giá ảnh hưởng của chế phẩm synbiotic gồm vi khuẩn sinh axit lactic Lactococcus lactis và fructooligosaccharide lên các chỉ tiêu miễn dịch của tôm thẻ chân trắng (Litopenaeus vannamei). Tôm thí nghiệm (khối lượng ban đầu 5 ± 0,6 g/con) được cho ăn thức ăn công nghiệp không có hoặc có chế phẩm synbiotic với hàm lượng phối trộn vi khuẩn L. lactis 108 CFU/mL và lần lượt 4 hàm lượng của fructooligosaccharide là 0,1; 0,2; 0,5 và 1%. Sau 30 ngày cho tôm ăn thức ăn thử nghiệm, tiến hành thu mẫu máu tôm để phân tích các chỉ tiêu miễn dịch. Kết quả cho thấy tổng số tế bào máu, hoạt tính của enzyme phenoloxidase và hoạt động thực bào của tôm cho ăn theo chế độ ăn có bổ sung chế phẩm synbiotic cao hơn (p<0,05) so với tôm ở nghiệm thức đối chứng, trong đó chế độ ăn có chế phẩm synbiotic chứa hàm lượng fructooligosaccharide 0,5% và 1% được ghi nhận có hiệu quả tốt hơn ở tôm thí nghiệm so với tôm ở các chế độ ăn còn lại. Tuy nhiên, hoạt tính enzyme lysozyme của tôm không khác nhau ở nghiệm thức đối chứng và tôm ở các nghiệm thức cho ăn chế phẩm synbiotic (p>0,05). Những kết quả đạt được trong nghiên cứu này bước đầu cho thấy chế phẩm synbiotic thử nghiệm đã làm tăng hoạt động miễn dịch của tôm thẻ chân trắng.
Abstract
This study initially evaluated the effect of a synbiotic containing a mixture of lactic acid-producing bacteria L. lactis and fructooligosaccharide on immune response factors of white leg shrimp (L. vannamei). The experimental shrimp (5 ± 0,6 g/con) were fed commercial feed without or containing the synbiotic with L. lactis (108 CFU/mL) and/or 4 concentrations of fructooligosaccharide 0,1; 0,2; 0,5 and 1%, respectively. After 30 days of feeding trial, shrimp hemolymph was collected to analyze the related parameters to shrimp immune response. The results showed that the immunological parameters such as total hemocytes count, phenoloxidase enzyme activity, and phagocytic activity of shrimp in the treated groups were significantly higher (p <0,05) than those of shrimp in the control group. In which, the diet containing synbiotic with 0,5% and 1% of fructooligosaccharide gave the better immune response in shrimp than others. In addition, there was no significant difference was observed in the lysozyme enzyme activity of shrimp in the treatment groups and the control group (p>0,05). The results of this study provided scientific data on the effectiveness of synbiotic in stimulating immune response parameters of cultured white leg shrimp.

Architecture, as a tool to raise awareness to climate change and sea level rise: case of Libyan coastal city of Zuwara
Authors: Chalgham Manal , Başer Kalyoncuoğlu Bahar 
Published: April 2021

The effects of climate change are no longer just a possibility we will face in the future. Droughts, wildfires, storms, sea surges, and much more, are climate change-related risks that communities around the world are facing today, coastal communities are particularly under the risk of floods and sea-level rise, but how aware are these communities of these threats? This study sets out to assess social awareness to climate change amongst the residents of the coastal Libyan city of Zuwara, which faces the risk of floods and sea level rise (SLR). The awareness level of the society about the factors of climate change can create significant barrier in front of mitigation and adaptation process. From this point of view, the study suggests that using a tool that publicly understandable and having familiarity with can have a greater impact on the level of awareness. Therefore, it has been focused on the role of architecture as a tool to raise awareness of the risks of climate change. The research methodology relies on a case study with future projections regarding Sea level rise (SLR) under different Representative concentration pathway (RCP), and a social survey designed in three stages: First step is measuring the level of awareness of residents of the city, then in the second attempt to rise it using architecture as an educative tool, and finally re-measuring the level of awareness in order to test the effectiveness of architecture as proposed tool. The questionnaire was distributed online to a sample of 100 people including participants who are of professional backgrounds in architecture and built environment. Statistical analysis of the questionnaire was divided into two stages, first, measuring the level of general awareness of the respondents about their living environment and climate change, then measuring the level of improvement in awareness about climate change during the survey. The second section of the questionnaire was formulated based on Likert scale, and to test the study’s hypotheses, (T - Test) and Independent Samples Test, were used. Survey results have shown an increase in the degree of awareness between participants when comparing answers before stage two and after, suggesting that using architecture as an educative tool to raise awareness about climate change; is effective.

IntroductionIn order to select high-risk patients, many prognostic scales have been invented. Among them, Rockall, Glasgow-Blatchford and AIMS 65 scales were considered the most useful.Material and methodsPatients with upper GI tract bleeding, treated between 2017 and 2018 were retrospectively enrolled to the study. Every patient had a Rockall, Glasgow-Blatchford and AIMS 65 score calculated retrospectively. Data on hospitalization as blood transfusions, length of hospital stay, rebleeding, intensive care unit (ICU) admission, mortality was included into data-base.ResultsUnivariate logistic regression revealed that only the AIMS65 scale was a prognostic factor for in-hospital mortality (OR 11.028; 95% CI: [2.271, 53.563], p=0.001). The AIMS 65 score >2 was the only factor predicting the need of >4 blood units transfusion during hospitalization (OR 3.977; 95% CI: [1.305, 12.122], p=0.015), whereas Glasgow-Blatchford scale >5 was the only risk factor for the need of fresh frozen plasma transfusion (OR 3.657; 95% CI: [1.010-13.242], p=0.048). The area under a curve (AUC) in the ROC analysis revealed that the AIMS 65 scale was the most accurate in mortality prediction (AUC=0.859, p=0.002), whereas Rockall score and Glasgow-Blatchford were not significant (AUC=0.614, p=0.093 and AUC=0.504, p=0.97, respectively).ConclusionsBased on our results, we recommend using AIMS 65 scoring system. It’s simple and requires few of parameters to be counted. Also, it proved to be the most efficient in predicting in-hospital mortality.
Classe inversée : quels obstacles en formation des enseignants dans le contexte français ?
Authors: Calistri Carole , Lapique Virginie 
Published: April 2021

En ce début de XXIe siècle, l’enseignement supérieur doit relever de nombreux défis et permettre la réussite des étudiants, et ces défis se posent avec une acuité particulière dans le domaine de la formation des enseignants français, puisque ces derniers se voient confier la responsabilité d’une classe pour leur année de stage. Le cheminement de deuxième année de Master en vigueur dans notre université octroie trente heures de formation à la didactique du français. Dans ce contexte, nous avons fait l’hypothèse que la classe inversée offre une perspective intéressante en permettant de « repousser » les limites de l’espace-temps de la formation en présentiel. Plus précisément, notre problématique vise à se demander dans quelle mesure la classe inversée est adaptée au contexte spécifique de la formation des enseignants français, et pourrait favoriser en particulier leur développement professionnel. Des éléments de réponse sont fournis par l’analyse d’entretiens semi-directifs menés avec des étudiants stagiaires, qui permettent d’identifier et de sérier un certain nombre d’obstacles et de freins.
Création et évaluation d’un prototype de jeu sérieux dédié à l’amélioration de la lecture chez les enfants présentant des symptômes de dyslexie
Authors: Lewis Francois , Plante Patrick 
Published: April 2021

Cet article, qui est la synthèse d’un mémoire de maîtrise, a principalement trois objectifs. Le premier objectif consiste à développer une méthodologie de conception de jeu sérieux éducatif (JSÉ) permettant spécifiquement d’aider les enfants qui éprouvent des difficultés en lecture ou qui présentent des symptômes associés à la dyslexie développementale. Le deuxième objectif consiste à réaliser un prototype Alpha du jeu, et le troisième objectif consiste à évaluer la cohérence du scénario ainsi que l’ergonomie du jeu par un test utilisateur.
Les travaux de Green et Bavellier (2012) indiquent que jouer à des jeux vidéo d’action améliore l’attention et l’apprentissage. Tandis que la recherche de Franceschini, Gori, Ruffino, Molteni et Facoetti (2013) démontre que l’utilisation d’un jeu vidéo d’action sans dimension sérieuse améliore la concentration et la vitesse de lecture des enfants dyslexiques.
Dans le cadre de cette recherche, nous croyons que l’ajout d’exercices de rééducation en lecture à un jeu vidéo d’action améliorera son efficacité pour l’apprentissage de la lecture des enfants présentant des symptômes associés à la dyslexie.
Les résultats de l’expérimentation portant sur la cohérence du scénario ainsi que sur l’ergonomie du jeu sont prometteurs. Des modifications devront être effectuées, notamment au niveau de la navigation et de l’optimisation des missions du jeu.
L'approche de formation hybride comme méthode d’enseignement facilitant la compréhension en lecture d’un cours de spécialité dispensé en FLE au supérieur Algérien
Authors: Khelfi Amira 
Published: April 2021

Notre problématique de recherche est née d’un double constat établi à partir d’une observation personnelle faite auprès d’apprenants arabophones confrontés à la compréhension en lecture des contenus pédagogiques, qui au travers de nos lecture a été davantage consolidée, notamment avec les travaux de (Boudechiche, 2008), (Sebane M. , 2008) et (Rekrak, 2016) dans lesquels ils ont démontrés avec clarté que les étudiants, en tentant de construire des connaissances en français langue étrangère, rencontraient beaucoup de difficultés.
Nous supposons que l’exploitation des multiples apports d’une plateforme d’apprentissage en ligne « MoodleCloud » dans le cadre d’un enseignement hybride permettrait d’enrichir l’enseignement dispensé en classe et de développer au mieux la compétence de compréhension en lecture de ces étudiants.
Afin de vérifier nos hypothèses de recherche, nous avons mené tout au long d’un semestre d’étude une enquête sur terrain qui s’est déroulée en trois phases auprès d’étudiants algériens inscrits en 1ére année Licence au département de Français.
La classe virtuelle synchrone à l'université, un levier de transformation de la professionnalité enseignante?

Published: April 2021

L’intégration des classes virtuelles synchrones modifie-t-elle la professionnalité enseignante et quelles sont les transformations qui en résultent ? Cette recherche réalisée auprès des enseignants dans le campus numérique Forse de l’université de Rouen illustre que les dispositifs de communication médiatisée rendent possible de nouvelles modalités d’intervention, en soirée et dans la cadre à ce qui pourrait relever du télétravail. C’est donc l’agir professionnel enseignant qui s’en trouve questionné, dans ses dimensions institutionnelles, épistémiques et ce qui fonde l’agir professionnel enseignant dans son expression, comme l’absence du corps instituant de l’enseignant.
Participación en Instituciones de la Democracia Participativa: el aporte discriminante de variables sociopsicológicas
Authors: Sorribas Patricia Mariel 
Published: April 2021

En el presente trabajo se identifican variables que discriminan entre personas que participan y quienes no participan en instituciones enmarcadas en una concepción participativa de la democracia que implican complejos comportamientos participativos. Se realizó un estudio por encuesta a mayores de 16 años (N = 663) en dos ciudades de Argentina (Córdoba y Villa María). El análisis discriminante permitió reconocer el aporte de actitudes ideológicas, información política movilizante, motivación, atribuciones causales internas, normas de ciudadanía y confianza política. Estos resultados son consistentes con los obtenidos en otros estudios que adoptan un enfoque psicosocial y variables similares. A su vez, permiten poner en cuestión el carácter democratizante e igualador de estas instituciones y justifican nuevas indagaciones que permitan establecer si se confirma esta tendencia y —a la par— avanzar hacia la comprensión de los factores que la condicionen.
Is the Episodic Buffer of Baddeley independent of the Central Executive? A new measure of the Episodic Buffer
Authors: Vila Chaves José Óscar , Gutiérrez Martínez Francisco , García Madruga Juan Antonio 
Published: April 2021

El Retén Episódico (RE) está tomando un creciente papel central en las explicaciones sobre el funcionamiento de la memoria operativa. De hecho, los últimos estudios de Baddeley y sus colaboradores sitúan al RE en el corazón del sistema de memoria. Recientemente la discusión también atañe a si este componente de la memoria operativa presenta una naturaleza independiente respecto a los recursos del ejecutivo central. Algunos estudios muestran como en tareas automatizadas, la construcción y mantenimiento de elementos almacenados en el RE no requieren de recursos desde el ejecutivo central.
El presente trabajo pretende analizar esta cuestión para lo que se toman diferentes variables y se ha diseñado un nuevo test para medir el EB. En este test de doble tarea, la tarea secundaria consiste en la lectura de textos sencillos que contienen palabras ocultas. Los resultados muestran como a pesar del aumento del procesamiento debido al incremento de la longitud de los textos, no se produce un aumento en la carga demandada por el ejecutivo central, ni en la creación de los agrupamientos de información ni en su mantenimiento. Es por ello, que pensamos que el RE bajo ciertas circunstancias es independiente del ejecutivo central.
The Episodic Buffer (EB) is taking on an increasingly central role in explanations regarding the functioning of working memory. In fact, in the most recent studies by Baddeley and his collaborators, the EB has situated itself at the core of this memory system. Recently under discussion is that this component of working memory seems to demonstrate an independent nature with respect to central executive resourcing. Some studies show that in automatic tasks the creation and maintenance of elements stored in the episodic buffer do not require resources from the central executive.
The current work attempts to evaluate this assumption for what different variables are taken and a new test has been developed to measure the EB. In this double task test, the secondary task consists of reading short simple texts that contain missing words. The results show that further processing due to increasing the length of the texts does not correspond to higher load demands made on the central executive, nor in the creation (organization) of chucks or their maintenance. Thus, we believe the EB is under certain circumstances independent of the central executive.

El objetivo del presente estudio es analizar si la curiosidad es una variable moderadora entre la Impulsividad y la Orientación Emprendedora. Se utiliza una muestra multiocupacional de 883 empleados españoles (49 % hombres, 51 % mujeres), obtenidos mediante un muestreo no probabilístico. Se ha utilizado el programa SPSS 23.0. Se encontraron correlaciones estadísticamente significativas entre todas las variables de la investigación a excepcion de la impulsividad Funcional. Finalmente, la evidencia empírica indica que la Curiosidad-D tiene un papel moderador entre la impulsividad Disfuncional y la Orientación Emprendedora mostrada, en el sentido de que la Curiosidad-D (entendida como una variable cuantitativa) afecta la intensidad de la relación entre la Impulsividad Disfuncional (variable predictora) y la Orientación Emprendedora (variable de criterio).
The objective of the present study is to analyze whether the variable Curiosity is a moderating variable between Impulsivity and Entrepreneurial Orientation. The multi-occupational sample of 883 Spanish and Colombian employees (49% men, 51% women) was obtained through non-probabilistic sampling. The data collected were processed with the SPSS 23.0 program. Statistically significant correlations were found among all the research variables except for Functional Impulsivity. Finally, empirical evidence indicates that Curiosity-D plays a moderating role between Dysfunctional Impulsivity and Entrepreneurial Orientation in the sense that Curiosity-D (understood as a quantitative variable) affects the intensity of the relationship between Dysfunctional Impulsivity (predictor variable) and Entrepreneurial Orientation (criterion variable).

Aim: This study evaluated PAH content and health risks associated with consuming Clarais gariepinus (cat fish) from Ekulu Rivers, in Enugu, Nigeria fed with roofing sheet company effluent.
Place and Duration of Study Design: Ekulu River, the largest body of water in the city of Enugu in Enugu State, south-eastern Nigeria, is a 25-kilometer long river (16mi) and it originates in the same city as well. The city is located on latitude 06o 21o N and 06o 30o and longitude 07o 26o E and 07o 37 Eo.
Methodology: This analysis was conducted with the use of Gas Chromatography – Mass Spectroscopy (GC-MS) machine equipped with Flame ionization detector (FID). The health risks were evaluated by the mathematical models stipulated by USEPA and WHO.
Results: The PAHs identified from the Clarias gariepinus samples were Acenaphthene, Acenaphthylene, Naphthalene, Fluorene, Phenanthrene, Anthracene, Flouranthene, Pyrene, Benzo(α)pyrene and Benzo (g-h-i)perylene. Benzo(α)pyrene and Benzo (g-h-i)perylene were predominant. The quantity of PAHs detected in all fish samples including the control ranged from below detectable limit (BDL) through 0.001 to 0.0786mg/kg. The LMW PAHs detected were 60 % while the HMW PAHs were 40 % of the total PAHs in isolated. The total PAH concentration observed from the different point locations were 0.1003 mg/kg, 0.0977 mg/kg, 0.1102 mg/kg and 0.0414 mg/kg for the downstream, upstream, POD and control respectively. The HQ and HI obtained in all point locations were < 1. The ILCR of all the PAHs detected were in the range of 10-5 to 10-9. The benzo (α) pyrene in cat fish obtained from the POD has the most carcinogenic potency and also recorded the maximum limit (5E -03 mg/kg).
Conclusion: it is pertinent to enlighten the fish consumers and mongers on the dangers posed by the consumption of fish from Ekulu River and also caution industries with injudicious effluent disposal into water bodies.
Stereoisomerization during Molecular Packing

Published: April 2021

AbstractIsomerization is an essential chemical process that often evokes dramatic change of chemical, physical, or biological properties. For a long time, isomerization has been known as a transformation that is induced by certain external energy such as light, heat, or mechanical force. Herein, a new isomerization phenomenon is described, which does not require external energy but simply occurs during molecular packing. The proposed isomerization is demonstrated by a series of symmetric donor–acceptor–donor (D–A–D) molecules, the donor of which may adopt two different stereoisomeric forms. Based on the evidence of the asymmetric isomers in crystals, the occurrence of isomerization during molecular packing is proved. Moreover, the unique asymmetric geometry in the solid state favors the restriction of intramolecular motion, resulting in highly efficient organic solids with quantum yields approaching unity.
Using Folding Structure to Enhance Measurement Range, Sensitivity of the Flexible Sensors: A Simple, Eco‐Friendly, and Effective Method
Authors: Zhu Junwen , Yang Xing , Zhou Zhanxuan , Ren Yuyu , Xing Yuqi 
Published: April 2021

AbstractFlexible sensing technology has shown great application value in motion monitoring and physiological signal detection. In many applications, the detected signal has the characteristics of low strength and wide range, thus improving the sensitivity and measurement range of sensors becomes extremely important. An enhancing method based on folding structure is proposed in this paper. Through the analysis of folding structure characteristics, the theoretical model of the folding structure effect in flexible sensors is established and the enhancement effect of sensitivity and measurement range is testified through three kinds of commonly used sensors, resistive, capacitive, and inductive sensors. Through changing the number of folding units, the sensitivity and measurement range of sensors can achieve to be adjusted. Folding sensors also have good hysteresis and repeatability properties and show the great performance in the application of human motion monitoring, such as limbs bending and rotating, muscle powering. The proposed method has the characteristics of simple, economical, environment friendly, and widely suitable, meanwhile avoiding the complexity of other ways to improve performance. This work has potential to enhance the sensitivity and measurement range for more kinds of flexible sensors and is of great value to fabricate high performance sensors based on folding structure.
