Os ambientes aquáticos, nas áreas urbanas e rurais, sofrem com as atividades antrópicas que afetam sua diversidade. Dentre as comunidades aquáticas, o zooplâncton é essencial para manutenção destes ecossistemas e podem indicar sua preservação. Neste trabalho, a comunidade zooplanctônica foi analisada em córregos rurais e urbanos. Os protozoários testáceos apresentaram maior número de táxons e abundância nas áreas rurais e os rotíferos foram evidenciados nos córregos urbanos. As características ambientais de córregos rurais e urbanos foram relevantes para a estrutura da comunidade do zooplâncton.

Os estudos existentes sobre blocos de fundação sobre três estacas foram desenvolvidos para pilares centrados, dificultando-se o entendimento do comportamento para modelos com pilares em posições distintas. Neste contexto, o presente trabalho busca, por meio de simulação computacional com variação da posição do pilar, analisar os fluxos de tensões e verificar as regiões nodais. Nas análises, percebe-se que a posição do pilar influencia diretamente nos fluxos de tensões e no comportamento dos blocos. Alguns modelos apresentaram estacas solicitadas apenas por esforços de compressão, em contrapartida, notou-se modelos onde as estacas foram solicitadas somente por esforços de tração.

In the context of virtual education that in recent years we have been forced to employ, the use of ICT played a fundamental role, especially since it is the main means of searching for information, which led us to the objective of determining the relationship that exists between the use of Information and Communication Technologies (ICT) and the development of skills in Information Literacy (IL) in university students. For this study, a correlational level methodology of non-experimental design was used, with a census-type population made up of 57 students of the Optometry career of the Federico Villarreal National University, to whom two questionnaires were applied both to measure the use of ICTs and for competence in information literacy in university students. After the statistical analysis in the SPSS program, the result was that the level of correlation was very low (0 < r < 0.2) and positive, that is, the greater the frequency of use of ICT, the greater the development of IL skills. , in turn, presented a significance of 0.040, so the null hypothesis was rejected, with a significance level of 5%, concluding that there is a statistically significant relationship between the frequency of use of ICT and the development of competencies in IL in Optometry students from UNFV Lima- 2021.

El objetivo del presente trabajo es la construcción de un modelo credit scoring de probabilidad con la finalidad de minimizar el riesgo de incumplimiento de pago de la cartera de clientes, para lo que se utilizó variables dependientes (cliente “bueno o malo”) y como independientes (características de los clientes) para proporcionar un análisis correcto para determinar si la empresa concede o no un crédito. Se aplicó la metodología descriptiva y enfoques cuantitativos y cualitativos tomando como fuentes primarias los datos de la cartera de clientes de la empresa SEGUMAR S.A. La base de datos consiste de la información de 100 personas solicitantes de un crédito y se incluye en la medición de 7 variables para cada persona. Cada solicitante se clasifica en una de dos categorías posibles, "buen cliente" (70 casos) o "mal cliente" (30 casos).  Se desarrolló una regla de credit scoring para determinar si un nuevo solicitante es “Bueno” o “Malo” cliente, basándose en los valores de una o más variables explicativas resultantes del modelo final. Este estudio evaluó las características que tienen los clientes al momento de pedir un crédito y según las características de cada cliente se puede realizar predicciones, clasificarlos como un buen o un mal cliente. En los resultados obtenidos del modelo Logit se puede concluir que las variables seleccionadas que se aplicaron en el modelo arrojaron un 76% de éxito que nos permite clasificar a cada uno de nuestros clientes como un buen cliente o mal cliente en nuestro modelo.
Identification of Hazards in Meat Products Manufactured From Cultured Animal Cells
Authors:   Food Standards Agency
Published: March 2023

Culturing of animal cells was developed in the late 19th and early 20th century, when researchers worked out how to support the growth of cells in media in an ex-vivo environment(footnote). The technology has been used commercially in the medical products industry, notably to produce antibodies for use as new medicines and as reagents in diagnostics. Animal cell culturing has expanded into the food industry especially due to its benefit in promoting sustainability for example by freeing up global arable land used for livestock farming, with cultured meat predicted to enter the UK market in the coming year(s) and already on the market in Singapore. With this in sight, a systematic search protocol was devised to identify hazardous concerns that will help inform the risk assessment for any future applications for authorisation to the FSA. To note, the term ‘cultured’ is now referred to as ‘cultivated’ but the report uses the former term to keep in line with the search string used for the research. This report was limited to meat products manufactured from cultured animal cells. Even though majority of these hazards cross-over to other products such as fish, there is potential to evaluate hazards associated with fish/seafood products separately in the near future. This hazard identification considers the nature of potential hazards associated with the production of cultured animal cells; a novel technology that uses animal cells and cell culturing to produce a substance that resembles meat thus avoiding animal rearing for meat products or aquaculture. As cultured animal cells may pose new risks this report aims to ‘scope out’ the technology to gain an understanding of it and to identify the potential risks that this may pose

The fruit wines from blueberry were made by microvinification procedure. Wines were produced in the absence or presence of sugar and/or enzymatic preparation glycosidase (EPG). Selected phenolic acids were quantified using UPLC/MS-MS analysis. Total phenolic content (TPC) was determined by the Folin-Ciocalteu method. Also, 2,2-diphenyl-1-picrylhydrazyl (DPPH) and ferric reducing ability of plasma (FRAP) methods were applied. The α-glucosidase inhibitory activity of blueberry wines was also investigated. Wines made with addition of sugar and EPG showed the best results. Phenolic profile and biological activity of blueberry wine depended from microvinification procedure which was used in the production.

In the generation of technological advancement, students tend to have difficulty learning science education since it encompasses numerous fields, making it challenging for students to assimilate knowledge about the topic. An approach called game-based learning exhibits positive results in students' academic performance where teachers integrate a learning approach for students to engage and motivate them throughout the learning process. Since there is a lack of empirical evidence, this metaanalysis study conducted a systematic literature review that seeks to know the methods, theoretical foundations, and educational outcomes of game-based learning in science education. This study includes a document analysis of 26 empirical literature studies from 2016 to 2021. Significant findings include that (1) most articles employed quasi-experimental research design, (2) most empirical studies utilized strategy games as the game genre, (3) most learning theories associated with science game-based learning are rooted in constructivism, and (4) most commonly observed science game-based learning outcomes focus on knowledge attainment among reviewed empirical literature. Significant findings imply that game-based learning is effective and can become productive for students in science learning.

El fenómeno de los esports ha venido creciendo de manera exponencial durante los últimos años. Numerosos equipos han creado centros de alto rendimiento para generar deportistas cada vez más competitivos. Diferentes estudios han indicado la importancia del entrenamiento en los jugadores de esports. El objetivo de este trabajo fue realizar una revisión sistemática sobre los artículos científicos publicados en los últimos 10 años (2012-2022) sobre el entrenamiento en jugadores de esports. Se realizó una búsqueda en PubMed con las palabras clave “esports” y “training”. En la revisión se incluyeron trabajos en inglés, que reportaran información cuantitativa sobre los entrenamientos y variables entrenables que tenga por objeto mejorar el rendimiento deportivo. En un primer paso se obtuvieron 62 artículos, pero únicamente 8 cumplieron los criterios de inclusión. A pesar de la importancia de la industria del videojuego en general y de los esports en concreto, han sido muy pocos los estudios encontrados sobre el entrenamiento para el rendimiento de las diferentes variables. Asimismo, los estudios encontrados no son concluyentes debido a que no se pueden contrastar, tienen un pobre diseño, o mezclan criterios de elegibilidad de la muestra.

Abstract. The esports phenomenon has been growing exponentially in recent years. Numerous teams have created high performance centres to generate increasingly competitive athletes. Different studies have indicated the importance of training in esports players. This research aimed to conduct a systematic review of the scientific articles published in the last 10 years (2012-2022) on training in esports players. A PubMed search was conducted using the keywords "esports" and "training". The review included papers in English that reported quantitative information on training and trainable variables aimed at improving sports performance. In a first step, 62 articles were obtained, but only 8 met the inclusion criteria. Despite the importance of the video game industry in general and esports in particular, very few studies have been found on training for the performance of the different variables. Furthermore, the studies found are not conclusive because they cannot be contrasted, have a poor design, or mix sample eligibility criteria. This research highlights the need to develop longitudinal studies with intervention that expose causal relationships between the proposals and the performance improvement obtained.

El baloncesto es un deporte de equipo, en el que intervienen múltiples variables que afectan al rendimiento de los jugadores. Tanto en los partidos de competición, como en el entrenamiento, los jugadores deben ponerse a prueba para dar lo mejor de ellos mismos. La intención del estudio fue analizar los efectos cardíacos y efectos emocionales que producen los diferentes dominios de acción motriz (tareas psicomotrices, de oposición, de cooperación y cooperación-oposición) sobre los jugadores de un equipo de baloncesto sénior. El estudio se realizó con 10 jugadores de un equipo de baloncesto. Se emplearon 22 tareas motrices de diferentes dominios de acción motriz. En cada tarea se analizó la frecuencia cardíaca media y el porcentaje de la frecuencia cardíaca máxima teórica de las tareas (Variables fisiológicas), a través del “Polar Accurex Plus” y la intensidad emocional mediante la Games and Emotion Scale, GES (Variable emocional). Los resultados confirman que cada familia de tareas desencadena comportamientos fisiológicos y emocionales desiguales. Este hallazgo aporta criterios científicos para la selección de las tareas motrices en el entrenamiento; además ayuda a comprender mejor los efectos fisiológicos y emocionales del baloncesto.

Abstract. Basketball is a team sport, in which multiple variables affect the performance of the players. Both in competitive matches and in training, players must be tested to give the best of themselves. The intention of the study was to analyse the cardiac effects and emotional effects produced by the different motor action domains (psychomotor, opposition, cooperation and cooperation-opposition tasks) on the players of a senior basketball team. The study was carried out with 10 players of a basketball team. Twenty-two motor tasks from different motor action domains were used. For each task, the average heart rate and the percentage of the maximum theoretical heart rate of the tasks (physiological variables) were analysed using the "Polar Accurex Plus" and the emotional intensity using the Games and Emotion Scale, GES (Emotional Variable). The results confirm that each task family triggers unequal physiological and emotional behaviours. This finding provides scientific criteria for the selection of motor tasks in training and helps to better understand the physiological and emotional effects of basketball.

The purpose of this research was to test whether the neuromotricity activities of the BAPNE method based on the dual task could improve selective attention and concentration in 5th grade primary school pupils. A quantitative approach was used, with a quasi-experimental design between subjects and with repeated measures before and after the intervention (pretest-intervention-posttest). The research was carried out in two schools in Alicante (Spain). The sample consisted of N=114 students between 10 and 11 years of age with similar socio-economic and cultural characteristics. A non-probabilistic convenience sampling was used, dividing the sample into an experimental group (n=66) and a control group (n=48). The Spanish adaptation of the d2 attention test was used as the assessment instrument. Statistical data were processed using SPSS, JASP and Excel. Statistical decision-making was based on a significance level of alpha=0.05. Samples were tested for normality, parametric and non-parametric tests were applied, and effect sizes were calculated. The main results of the intra-subjects analysis were statistically significant in favour of the experimental group in the variables TRPOST (p=<.001), DifTR (p=<. 001), TAPOST (p=.025), DifTA (p=.021), CPOST (p=<.001), DifC (p=.021), VARPOST (p=<.001), DifVAR (p=.002), TR+POST (p=<.001), and DifTR+ (p=<.001). Three variables that showed differences in the pretest were invalidated. The within-subjects analysis was also favourable for the experimental group. In conclusion, an affirmative answer to the purpose of this research is presented.

Les protestants français et la Saint-Barthélemy (1972-2023)
Authors: Ropp Laurent
Published: March 2023

En 1972 comme en 2023, les protestants réunis à Mialet lors de l’assemblée du Musée du Désert ont commémoré la Saint-Barthélemy, un événement du XVIe siècle dont le souvenir occupe une place centrale dans les représentations historiques des héritiers de la Réforme. Cet article a pour objectif de sonder la mémoire de 1572 chez les protestants français au cours du dernier demi-siècle afin de comprendre dans quelle mesure les mutations des contextes religieux, historiographique et géopolitique ont transformé les images et les usages de ce massacre lointain. L’examen des réactivations du souvenir de la Saint-Barthélemy montre que la mémoire de l’épisode est restée vive chez les protestants français. L’analyse des discours historiques des successeurs des huguenots révèle qu’ils ne reflètent que partiellement l’évolution de l’historiographie. Enfin, l’événement fait l’objet d’utilisations multiples, en résonance avec l’actualité.
Maurevert : étude de l’activité d’un tueur et de son entourage à partir des actes notariés
Authors: Hellin Stéphan
Published: March 2023

Charles de Louviers, seigneur de Maurevert, n’est pas seulement l’auteur de l’attentat contre Coligny, le 22 août 1572 : c’est aussi un noble provincial. À travers l’étude de ses actes notariés passés à Chaume-en-Brie, près de son château, nous avons cherché à comprendre ses choix de vie et à connaître son entourage, en particulier pour l’année 1572. Maurevert passe en juin 1572 plusieurs actes significatifs qui montrent qu’il anticipe un départ de son château deux mois avant le crime contre Coligny (mise en fermage de ses terres, procurations diverses). Cette démarche démontre une organisation du complot bien antérieure au 22 août 1572, et non un crime bâclé dans l’urgence. Par ailleurs, l’entourage de Maurevert est bien intégré à la cour : la cousine germaine de son épouse, Anne d’Acquaviva, est la maîtresse de Charles IX en mars 1572 ; son voisin, l’abbé de Chaumes, Jean de Gondi, est le frère du comte de Retz, le responsable des services secrets de Catherine de Médicis. Enfin, un de ses amis, Jean Hanoyer, connaît une ascension sociale en devenant prévôt de Chaumes en décembre 1572. L’ensemble des éléments rassemblés montrent que l’attentat du 22 août a été soigneusement préparé par le tueur dès le mois de juin 1572 et que Maurevert a bénéficié d’un soutien du pouvoir royal pour la promotion d’un ami peu après la Saint-Barthélemy.
La mémoire protestante de la Saint-Barthélemy en France
Authors: Millet Olivier
Published: March 2023

Quelle fut la vision protestante de la Saint-Barthélemy ? Le scénario explicatif le plus souvent retenu au XVIe> siècle est celui de la trahison royale préméditée, voire d’un complot du pape et de l’Espagne. Une histoire presque immédiate se constitue, notamment sous la forme du martyrologe, qui égrène les noms des victimes et les récits particuliers. Les protestants contemporains de la Saint-Barthélemy n’ont pas produit d’œuvre mémorable et originale qui construise une mémoire particulière de l’événement (Les Tragiques d’Aubigné sont à part) ; leur effort a surtout porté sur la redéfinition politique de la monarchie. Durant le XVIIe siècle, les réformés sont sur la défensive et obligés à une oubliance discrète sur le passé des Guerres de religion, y compris le massacre. À partir de la seconde moitié du XVIIIe siècle, la Saint-Barthélemy est devenue peu à peu une référence partagée par la grande majorité de la nation. Ce sont surtout des non-protestants (Voltaire) qui se sont emparés de sa mémoire pour mener des combats nouveaux, contre le fanatisme, la tyrannie ou l’intolérance. Les huguenots ont adhéré à cette vision, qui les intégrait dans une mémoire commune à l’ensemble de la nation. Ils ont pu ainsi réassumer, dans cette nouvelle perspective, leur propre souvenir de la Saint-Barthélemy, et participer aux débats historiographiques qui se poursuivent désormais sans passion.
« Moi estant dedans Troyes »
Authors: Roberts Penny
Published: March 2023

À la suite du tristement célèbre massacre de la Saint-Barthélemy d’août 1572 à Paris, les communautés de huguenots d’au moins une douzaine de villes françaises ont subi des actes de violence au cours des jours et des semaines qui ont suivi. L’un d’entre eux a eu lieu à Troyes, en Champagne, où une quarantaine de huguenots ont été emmenés dans les prisons et, le 4 septembre, tués de sang-froid alors que certains de leurs compagnons étaient morts dans les rues les jours précédents. Bien que le nombre de victimes soit relativement faible par rapport aux événements survenus ailleurs, nous sommes bien informés sur ceux qui ont péri grâce à la survie des récits locaux du massacre. L’un des récits les plus importants est celui d’un témoin oculaire anonyme qui n’a jamais été publié dans son intégralité. Pour remédier à cet oubli, il est présenté ici avec une courte introduction et des notes fournissant des informations complémentaires provenant d’autres sources d’archives.
