The Placenta in Congenital Heart Disease: Form, Function and Outcomes
Authors: Josowitz Rebecca , Linn Rebecca , Rychik Jack
Published: September 2023

The maternal-fetal environment, controlled and modulated by the placenta, plays a critical role in the development and well-being of the fetus, with long-term impact through programming of lifelong health. The fetal cardiovascular system and placenta emerge at the same time embryologically, and thus placental form and function are altered in the presence of congenital heart disease (CHD). In this review, we report on what is known about the placenta from a structural and functional perspective when there is CHD. We describe the various unique pathologic findings as well as the diagnostic imaging tools used to characterize placental function in utero. With growing interest in the placenta, a standardized approach to characterizing placental pathology has emerged. Furthermore, application of ultrasonography techniques and magnetic resonance imaging now allow for insights into placental blood flow and functionality in vivo. An improved understanding of the intriguing relationship between the placenta and the fetal cardiovascular system will provide opportunities to develop novel ways to optimize outcomes. Once better understood, therapeutic modulation of placental function offered during the vulnerable period of fetal plasticity may be one of the most impactful ways to alter the course of CHD and its complications.

OBJECTIVES

In infants with hypoxic-ischemic encephalopathy (HIE), conflicting information on the association between early glucose homeostasis and outcome exists. We characterized glycemic profiles in the first 12 hours after birth and their association with death and neurodevelopmental impairment (NDI) in neonates with moderate or severe HIE undergoing therapeutic hypothermia.

METHODS

This post hoc analysis of the High-dose Erythropoietin for Asphyxia and Encephalopathy trial included n = 491 neonates who had blood glucose (BG) values recorded within 12 hours of birth. Newborns were categorized based on their most extreme BG value. BG >200 mg/dL was defined as hyperglycemia, BG <50 mg/dL as hypoglycemia, and 50 to 200 mg/dL as euglycemia. Primary outcome was defined as death or any NDI at 22 to 36 months. We calculated odds ratios for death or NDI adjusted for factors influencing glycemic state (aOR).

RESULTS

Euglycemia was more common in neonates with moderate compared with severe HIE (63.6% vs 36.6%; P < .001). Although hypoglycemia occurred at similar rates in severe and moderate HIE (21.4% vs 19.5%; P = .67), hyperglycemia was more common in severe HIE (42.3% vs 16.9%; P < .001). Compared with euglycemic neonates, both, hypo- and hyperglycemic neonates had an increased aOR (95% confidence interval) for death or NDI (2.62; 1.47–4.67 and 1.77; 1.03–3.03) compared to those with euglycemia. Hypoglycemic neonates had an increased aOR for both death (2.85; 1.09–7.43) and NDI (2.50; 1.09–7.43), whereas hyperglycemic neonates had increased aOR of 2.52 (1.10–5.77) for death, but not NDI.

CONCLUSIONS

Glycemic profile differs between neonates with moderate and severe HIE, and initial glycemic state is associated death or NDI at 22 to 36 months.
Defining and Promoting Pediatric Pulmonary Health: Developing Biomarkers for Pulmonary Health
Authors: Davis Michael D. , Zein Joe G. , Carraro Silvia , Gaston Benjamin
Published: September 2023

Children with inherited and/or acquired respiratory disorders often arrive in adolescence and adulthood with diminished lung function that might have been detected and prevented had better mechanisms been available to identify and to assess progression of disease. Fortunately, advances in genetic assessments, low-cost diagnostics, and minimally- invasive novel biomarkers are being developed to detect and to treat respiratory diseases before they give rise to loss of life or lung function. This paper summarizes the Developing Biomarkers for Pulmonary Health sessions of the National Heart, Lung, and Blood Institute- sponsored 2021 Defining and Promoting Pediatric Pulmonary Health workshop. These sessions discussed genetic testing, pulse oximetry, exhaled nitric oxide, and novel biomarkers related to childhood lung diseases.

Published: September 2023

Lifelong respiratory health is rooted in the structural and functional development of the respiratory system in early life. Exposures and interventions antenatally through childhood can influence lung development into young adulthood, the life stage with the highest achievable lung function. Because early respiratory health sets the stage for adult lung function trajectories and risk of developing chronic obstructive pulmonary disease, understanding how to promote lung health in children will have far reaching personal and population benefits. To achieve this, it is critical to have accurate and precise measures of structural and functional lung development that track throughout life stages. From this foundation, evaluation of environmental, genetic, metabolic, and immune mechanisms involved in healthy lung development can be investigated. These goals require the involvement of general pediatricians, pediatric subspecialists, patients, and researchers to design and implement studies that are broadly generalizable and applicable to otherwise healthy and chronic disease populations. This National Institutes of Health workshop report details the key gaps and opportunities regarding lung function and structure.

Providing mankind with high-quality products of aquaculture is possible only by introduction of modern industrial technologies to fish farming, growing fish based on modern scientific achievements. Assessment of the ecotoxic situation and identification of impacts of various unfavourable factors of aquatic environment on aquatic organisms should be made through morphological studies of the organs that are first to encounter the impact. The study revealed species specifics of the morphology of the liver of the fishes of the Cyprinidae family – Prussian carp (Carassius gibelio), Eurasian carp (Cyprinus carpio), and bighead carp (Hypophthalmichthys nobilis), which vary by extent of the motor activity in the aquatic environment, nutrition, etc. We determined that during phylogenetic development of fish that grow in the aquatic environment, there occurs a certain restructuring of the liver: the adaptation to various living conditions were accompanied by changes in a number of parameters of macro- and microscopic architectonics of the liver. Cyprinus carpio and Carassius gibelio (omnivores) have a two-lobe liver, while Hypophthalmichthys nobilis (a herbivore) has a three-lobe liver. For C. carpio and H. nobilis, a characteristic feature of the liver was presence of the hepatopancreatitis (the liver and the pancreas, associated into a single organ), and in C. gibelio, they are differentiated into individual organs. A peculiarity of the microscopic structure of the liver of the Cyprinidae family is poorly developed interlobular connective tissue, and parenchyma of the liver lobule has a tubular structure as polyhedral, curved thick-walled tubules, the walls of which are hepatocytes. The greatest amounts of cytoplasm and karyoplasms were seen in C. gibelio, equaling respectively 12.98 ± 1.42 and 0.40 ± 0.02 µm³. The lowest volume of the indicated parameters was in C. carpio, particularly 2.97 ± 0.22 and 0.21 ± 0.01 µm³, respectively. The lowest nuclear-cytoplasmic ratio was observed in hepatocytes of C. gibelio (0.0316 ± 0.0024). The conducted morphological studies at the levels of organs, tissues and cells can reveal how the fishes’ bodies adapt to particular living conditions and impacts of environmental factors.
Histological and immunohistochemical changes in equine sarcoids
Authors: Portenko M. , Shchebentovska O. , Blishch H.
Published: September 2023

The article presents the results of histopathological and immunohistochemical studies of three types of equine skin neoplasms, classified as type 2 fibroblastic sarcoid based on their morphological features. The tumours were localized in the abdominal area, macroscopically presented as dense, fleshy formations without a stalk, yet with small ulcers on the surface. Infection of horses could have occurred through direct or indirect contact with other infected horses and cattle, as well as through insects. Histological examination of the sarcoid established that the epidermis was in a state of hyperkeratosis and acanthosis, with the formation of numerous projections that penetrated deeply into the dermis. The boundaries between the papillary and reticular layers of the dermis were not visualized; the defining feature was the chaotic spindle-shaped fibroblasts that formed a significant number of dense whirl-like structures, or moire patterns, which encircled vessels of a varying caliber. The cell nuclei were predominantly round-shaped and hyperchromatic. Present were both typical and atypical mitotic figures. Replacement of loose connective tissue with collagen fibers was observed intradermally. Upon studying the morphological structure of the sarcoid on semi-thin sections, significant vascularization was observed. Spindle-shaped fibrocytes with branched processes and elongated nuclei were located around vessels of varying sizes, exhibiting well-differentiated single or double nuclei. Fibroblasts of various shapes and sizes with round nuclei were randomly distributed throughout the entire area of the neoplasm. The bulk of the sarcoid consisted of collagen fibers, which turned pink when exposed to methylene blue and further exposure to acid fuchsin. Immunohistochemical studies revealed intense vimentin-positive expression in the sarcoid cells, confirming the hypothesis of their mesodermal origin. Upon detecting Ki-67 antibodies in the sarcoids from three clinical cases, a significant number of cells in the G1 and S phases of mitosis were discovered; the cell nuclei and karyoplasm were stained brown. These actively proliferating cells of the neoplasm constitute the "growth fraction" of the tumour and point to a high risk of recurrence and malignancy.
Literaturas del fin del mundo
Authors: Guizzo Antonio Rediver , Soalheiro Grade Maíra , Paez Florencia
Published: September 2023

En este artículo, analizamos cómo O Deus das avencas (2021), de Daniel Galera, participa de un grupo de narrativas que convencionamos llamar literaturas del fin del mundo – caracterizadas por la composición de enredos distópicos o post apocalípticos que figuran la asunción de regímenes totalitarios al poder, la reducción de grupos económicamente desfavorecidos  a la “vida desnuda”, el ahondamiento de la explotación de los recursos naturales y de las desigualdades sociales, la precarización del trabajo, la transformación de las tecnologías de comunicación en tecnologías de vigilancia, control y represión, y otros temores surgidos de las crisis democráticas y resurgimiento del capitalismo liberal. La obra O Deus das avencas (2021) está compuesta por tres cuentos que, aunque dispares, parecen constituir una gradación de las relaciones sociales y políticas del país hacia la ruptura de las formas de sociabilidad. El primer cuento, “O Deus das avencas”, presenta la agonía de una pareja que espera el nacimiento de su hijo ante la incertidumbre del rumbo político del país; la segunda, “Tokio”, narra una sociedad distópica en la que la severa devastación ambiental y la drástica reducción de las interacciones humanas se suman a la creencia en la posibilidad de trasladar la conciencia a dispositivos tecnológicos; la tercera, “Bugonia”, presenta un futuro postapocalíptico en el que la humanidad, en ausencia de tecnologías y bajo la amenaza de una patología contagiosa y letal, vuelve a formas tribales de sociabilidad y, para sobrevivir, establece una relación de mutualismo con abejas. En el análisis propuesto, dialogamos con investigadores que observan el crecimiento de la producción distópica en diferentes países y contextos sociopolíticos, como María Laura Pérez Gras (2017), Eirik Vassenden (2022), Tom Moylan (2018), Jill Lepore ( 2017), Gregory Claeys (2017), entre otros.
Prácticas para la equidad de género en la docencia universitaria dentro del contexto de la Universidad Nacional
Authors: Saborío-Taylor Silvia , Arguedas Víquez Rita
Published: September 2023

El presente ensayo se centra en la problemática de desigualdad de género en la educación superior, particularmente en la Universidad Nacional, Costa Rica. En la actualidad, aun cuando existen lineamientos y políticas para la equidad e igualdad de género en el contexto universitario, las prácticas docentes y la interrelación entre estudiantes siguen evidenciando que es un desafío latente y que aún los estereotipos con relación al género siguen teniendo presencia. El planteamiento de la transversalidad por parte de la docencia universitaria, su relación con el currículo oculto y las metodologías inclusivas son un medio para la interiorización y concientización de la relevancia de la igualdad y la equidad de género en el contexto educativo. Se busca proponer prácticas para la equidad de género en la docencia universitaria dentro del contexto de la Universidad Nacional desde el diseño de programas de curso y la implementación de metodologías inclusivas. Lo anterior se alcanza a partir de la utilización constante y evidente de lenguaje inclusivo, la inclusión equitativa de recursos bibliográficos en el curso, la potencialización y práctica de lemas propuestos a nivel institucional, el diseño de materiales educativos paritarios, espacios participativos en igualdad de condiciones y cursos específicos sobre la temática en cada ciclo lectivo. La equidad de género no se concreta solo en la práctica docente, por lo que se hace necesaria en la formación del profesorado, de ahí que deben surgir nuevas políticas universitarias para avalar metodologías de y para la inclusión, pues la transformación también debe apuntar a la igualdad y a la equidad de género.

Published: September 2023

El artículo tiene como objetivo analizar la situación laboral y académica de las mujeres graduadas universitarias, entre los años 2011 al 2016 en Costa Rica por medio de análisis estadísticos y zonas de análisis que permitan determinar la brecha laboral y académica entre hombres y mujeres. El análisis fue de carácter cuantitativo, que se basa en estadísticas descriptivas, construcción de indicadores laborales y razones estadísticas. Se tomaron en cuenta las bases de datos de los Estudios de seguimiento de la condición laboral de las personas graduadas de las universidades costarricenses, en los periodos 2011-2013 y 2014-2016, datos recolectados en los años 2016 y 2019, respectivamente. Se contó con una muestra de 14 435 personas graduadas de las universidades públicas y privadas. Los resultados mostraron que para las mujeres se presentan brechas de desempleo en las cuatro zonas de análisis (piedra, evolución, riesgo y 4.0). En el indicador de relación del empleo con la carrera, en dos de las cuatro zonas presentan resultados desfavorables, lo mismo que en el indicador de subempleo por insuficiencia de horas (personas que no logran una jornada laboral completa). En conjunto con el análisis de los tres indicadores laborales, aunque las mujeres tengan una formación en ciencia, tecnología, matemática e ingeniería, no logran posicionarse en el mercado de trabajo bajo las mismas condiciones que los hombres, por lo que las brechas de género continúan en todas las zonas de análisis y son mayores en la Zona de evolución y 4.0.

Published: September 2023

Este artículo muestra los hallazgos de un estudio interdisciplinario inscrito en el Instituto de Investigación en Educación (INIE), realizado por dos investigadoras de diferentes áreas, una de Orientación y la otra de Educación Especial, el cual tuvo como objetivo general analizar las acciones colaborativas para la promoción del éxito escolar en cuatro centros educativos de San José, Costa Rica, en el año 2019. El éxito escolar se entiende no solo como la obtención de buenas calificaciones, sino como el desarrollo integral (cognitivo, socioafectivo y psicomotor) de las personas estudiantes y su participación plena en el contexto educativo como promotores de la inclusión social. Se realizó un estudio cualitativo de diseño fenomenológico, con la aplicación de entrevistas semiestructuradas a profesionales de las áreas de I y II ciclo de Educación General Básica, Orientación y Educación Especial. Los datos se organizaron en tres grandes categorías que dieron como resultado: la identificación de actividades colaborativas para la promoción del éxito escolar, aportes de cada disciplina en este trabajo conjunto y acciones que propician el éxito en el estudiantado. La principal conclusión del estudio es que la promoción del éxito escolar integral es altamente pertinente y se hace más viable mediante el trabajo colaborativo entre profesionales de las diferentes disciplinas.
Orchids of the Southern Cone (1830–2000) – Part III. Karl Friedrich Reiche’s Orchidaceae Chilensis and a commentary about Friedrich Wilhelm Ludwig Kraenzlin’s Orchidacearum Genera et Species (Vol. 2, Part I)
Authors: Ossenbach Carlos
Published: September 2023

Karl Reiche (1860–1929), a German botanist, came to Chile in 1889 as a professor at the Lyceum in the city of Constitución. He was attracted by the country’s climate and its traditional friendliness to German immigrants. A few years later, in 1897, Federico Phillippi, Director of the Museo Nacional de Historia Natural, welcomed Reiche as the new Head of the Botanical Section, a position he held until 1910. During his 21 years in Chile, Reiche worked intensively on the Chilean flora and was a prolific writer. Besides six volumes of the Estudios críticos de la Flora de Chile (1896–1911), several editions of Reiche’s Plant Geography of Chile were published (1907, 1934–1937, 2013), a magnificent essay on Chiles’ Orchidaceae, Orchidaceae Chilensis (1910, reprint 2007), and several other minor works. On Reiche’s suggestion, The Museo Nacional engaged Friedrich Kraenzlin (1847–1934) to write a treatment of the orchids of the Southern Cone that was published in 1904 as the second volume of Orchidacearum Genera et Species, a work that was widely criticized by many botanists, beginning with Reiche himself.
Los Borges de Borges: la construcción de una alteridad particular
Authors: Calderón Sánchez Estefanía
Published: September 2023

La obra del argentino Jorge Luis Borges marcó un hito dentro de la historia literaria, dado que cuestionó muchos de los preceptos heredados de la tradición europea al formular una poética donde la ambigüedad, lo paródico y la inestabilidad son partes intrínsecas de su perspectiva literaria. Por ello, este artículo se centrará en uno de los temas más recurrentes del argentino: la alteridad, el cual permite no solo hablar de una construcción literaria particular, sino también acercarse a la figura de un escritor que se desdobla y se revela en sus textos. Así, los textos por analizar forman parte de dos de las producciones más importantes del argentino. Por un lado, “Los teólogos” y  “La busca de Averroes” pertenecen al libro El Aleph (1949) y, por otro, “El otro” es uno de los cuentos de El Libro de Arena (1975). Los tres han sido bastante citados por la crítica literaria; sin embargo, no se encontró ningún estudio donde se estableciera un diálogo entre ellos. Por ende, el presente análisis busca construir una perspectiva que permita enriquecer la discusión sobre la alteridad y su relación con los temas del doble y de la identidad dentro del mundo borgeano.

A Systems Thinking Approach to Computational Thinking in Education
Authors:   ,   Linnaeus University, Faculty of Technology, Department of Informatics, Hamidi Ali
Published: September 2023

In today's rapidly changing world, the acquisition of essential skills is crucial for the success of young individuals. Among these skills, computational thinking (CT) plays a vital role in problem-solving and adapting to the complex and evolving demands of the 21st century. However, there is a need to explore the integration of other thinking skills alongside CT, as well as their application in educational settings. This study aims to address the gap in knowledge regarding the application of systems thinking to the development of CT and its integration into education. The primary objective is to explore the relationship between systems thinking and CT, providing a contextual framework for existing studies that focus on systems thinking in relation to CT. Additionally, the study explores how systems thinking can be applied to CT within educational contexts. By incorporating a systems thinking approach, a broader examination of the various factors involved in CT, including the technological landscape, individual skills and knowledge, and the social and cultural context, can be achieved. The thesis comprises three papers that describe research efforts conducted over three years. These projects focused on CT development using educational robotics and maker technologies, aiming to build and enhance CT skills among individuals of different ages and perspectives. The findings of the research efforts are synthesized and consolidated using the systemic FMA model, a comprehensive model that interconnects the frameworks of ideas, methodology, and the area of interest. This model conceptualizes CT practices as a system encompassing emergent properties, multiple perspectives, design interventions, and social and ethical considerations. The adopted FMA model enables methodological pluralism and facilitates critical examination of the boundaries of CT development, leading to conceptual and practical changes. The research contributes to the field of CT by providing insights into its theoretical foundations and practical applications, informing and guiding educational practices that are associated with CT.

Introducción: La actividad laboral de las personas siempre ha transformado al mundo, sin embargo, ha generado muchos riesgos y enfermedades. Asimismo, el trabajo ha sido afectado por la globalización, la tecnología y la crisis sanitaria por la COVID-19. Generando, transformaciones en las estructuras del empleo y en las condiciones del trabajo, tornándose más exigente en el área laboral, estas condiciones han predispuesto factores psicosociales negativos que amenaza la salud; ocasionando enfermedades y accidentes laborales, y como consecuencia un deficiente rendimiento laboral. Objetivo: Determinar la relación entre los factores psicosociales y el rendimiento laboral en colaboradores de una institución educativa privada de Lima. Metodología: Enfoque cuantitativo, de diseño no experimental, corte transversal y de tipo correlacional. En el estudio participaron 120 colaboradores de la institución educativa privada, según el muestreo no probabilístico; como instrumento se aplicó el Cuestionario de “Factores Psicosociales en el Trabajo” y el “El cuestionario de Rendimiento Laboral Individual” compartido digitalmente través del correo electrónico. Resultados: del total de los encuestados, el 52,50% manifestaron tener una buena percepción de los factores psicosociales; sin embargo, se obtuvo una mala percepción en las dimensiones exigencia laboral con el 63,30% y satisfacción con la remuneración del rendimiento con el 52,50%; con respecto a la variable rendimiento laboral, el 75,00% demostró un nivel alto. Conclusión: Los trabajadores que indicaron una alta exigencia laboral tuvieron 11 veces mayor probabilidad de presentar un alto rendimiento en su trabajo (OR:11,03; IC 95%: 1,71-17,95).
The Post-Brexit Need for a Data Adequacy Decision to Engage in Mutual Assistance in Criminal Matters with the EU
Authors: Bruce Matthew
Published: September 2023

There is a need for the UK and EU to continue mutual assistance in criminal matters. As a Member State, Mutual assistance in criminal matters between was primarily governed by an EU convention. This convention builds on existing Council of Europe (CoE) conventions on mutual criminal assistance. The EU convention states that mutual assistance shall be afforded in proceedings brought by member states’ authorities, or in connection with proceedings where a person may be liable in the requesting member state. Title II provides a framework for specific forms of assistance including restitution, hearings via videoconference and covert investigations. Member states are free to conclude further bilateral arrangements. A key element of this mutual assistance is harmonised EU data protection laws. With the UK now outside the EU’s data protection architecture, this may pose a significant hurdle for future cooperation. This article critically analyses the need for a data adequacy decision from the EU for the UK to engage in mutual assistance in criminal matters post-Brexit. To reach a conclusion, the article is set out over three substantive areas considering: mutual assistance and data protection law as it applies to EU member states; the law underpinning adequacy decisions; and future legal developments post-Brexit. Specific examples of data transfers and the effect of the Trade and Cooperation Agreement (TCA) are compared and contrasted to adequacy decisions. While provisions of the TCA and EU Law Enforcement Directive (LED) provide some assurances, the article recommends that a data adequacy decision made under the LED is pursued.

Published: September 2023

Resumo No intuito de desvelar como se constituem oportunidades de aprendizagem profissional do professor que ensina Matemática, propõe-se neste artigo compreender como interações discursivas entre professores participantes de um processo de formação continuada promovem oportunidades para eles aprenderem sobre o ensino de padrões e regularidades. Os dados desse estudo qualitativo-interpretativo incluem vídeo e áudio gravação dos encontros; arquivos das tarefas; e registros escritos da formação. A organização das tarefas e a dinâmica implementada nas discussões coletivas propiciaram momentos de comunicação dialógica, privilegiando um discurso pedagógico exploratório, atrelado a um discurso matemático exploratório, assim como favoreceram discussões matemáticas e didáticas, com argumentações que articulam os conhecimentos profissionais abordados. Sendo assim, refinar a capacidade de reconhecer formas de discurso e de motivá-las ou responder a elas contribui para o desenvolvimento profissional docente.
Problemas matemáticos elaborados por docentes: un análisis desde la contextualización culturalmente significativa
Authors: Arroyo Gilberto Chavarría , Albanese Veronica
Published: September 2023

Resumen En este documento se reporta el análisis de problemas elaborados por docentes de secundaria, antes y después de la implementación de un curso de elaboración de problemas contextualizados mediante el uso de signos culturales. Se llevó a cabo un análisis de contenido, definiendo categorías a priori para los contextos y la contextualización de los problemas elaborados; en particular, se analizó la contextualización culturalmente significativa de los problemas a través de los componentes de autenticidad (evento, pregunta, propósito, datos). En general, el propósito de los problemas elaborados en el curso de formación se acercó más a la realidad del contexto sociocultural en comparación con los propuestos antes del curso. Sin embargo, persisten debilidades con respecto a presentar datos e información coherentes con la realidad del evento planteado en el problema, lo cual es un aspecto en el que se debe hacer más hincapié en futuros espacios de formación, para conseguir elaborar problemas más auténticos y culturalmente significativos.
Desafiando as Crianças na Formulação de Problemas
Authors: Miranda Paulo , Mamede Ema
Published: September 2023

Resumo A criatividade é um componente que tem sido cada vez mais valorizado na experiência matemática. Sendo a relação entre a Matemática e a criatividade reconhecida na comunidade acadêmica, ainda é pouco frequente a transposição dessa realidade para o meio escolar. Também os alunos devem ter oportunidades de experienciar e desenvolver tarefas que estimulem a sua criatividade matemática. A formulação de problemas pode ser entendida como um elo de ligação entre a estimulação da criatividade e as aprendizagens matemáticas dos alunos. Este artigo analisa as reações e os desempenhos de alunos do primeiro ano de escolaridade (N=22) quando desafiados a formular problemas. Aborda duas questões: 1) Como reagem os alunos às tarefas de formulação de problemas? 2) Como realizam os alunos tarefas de formulação de problemas? Neste artigo foram adotados métodos qualitativos, numa abordagem de estudo de caso, para descrever as reações e produções das crianças perante duas tarefas de formulação de problemas. Os resultados revelaram que as crianças foram capazes de propor problemas adequados e originais, observando-se que nenhum erro foi identificado na sua resolução matemática, mas identificando-se casos de dificuldades no estabelecimento da situação conceitualizada. Geralmente, os alunos assumiram-se como protagonistas nos seus problemas, criando situações que os envolviam a si ou aos seus colegas. Também se identificou que estes tendem a aglutinar os processos de formulação e resolução de problemas.

Abstract Establishing criteria that determine the quality of any scientific publication is a fact agreed on by the entire scientific community in its different fields of knowledge. In the case of doctoral theses, these criteria may vary between universities, doctoral schools, or evaluation committees. This paper presents an evaluation criteria proposal for doctoral theses in the field of Mathematics Education. A total of 199 theses indexed in the TESEO database are analyzed, throughout the 2015-2020 period. Likewise, after applying these criteria, those theses that have been denominated as “exemplary” are identified in this evaluative proposal. The main results include the consolidation of two university research centers in the field of Mathematics Education. However, results show the scarce dissemination that is made of the investigations carried out from the doctoral works (102 out of 199 doctoral theses have not had any associated publication) apparently having, as the main objective, the achievement of the Doctor’s degree instead of the search for development and scientific advancement.

ABSTRACT Individuals with trisomy 21 may have muscle hypotonia of the speech articulation organs, an enlarged protruding tongue positioned on the floor of the mouth, and a lack of lip closure. The stimulating palatal plate is an intraoral appliance that, associated with myofunctional therapy, aims to improve these children’s habitual lip and tongue posture. This study aimed to present the cases of four male children with trisomy 21, with a mean age of 6.7 and a standard deviation of 7.8 months, who used the stimulating palatal plate in association with myofunctional therapy. The children used the plate for 6 months and did exercises based on the orofacial regulation therapy, and their parents received instructions on feeding them and removing deleterious oral habits. In the first session and at the end of the treatment, each child’s face was video-recorded for 5 minutes at rest, and two researchers analyzed independently their habitual tongue and lip posture. Participants who began the treatment earlier and had the most severe postural changes had greater tongue and lip posture improvement.

Cervical cancer is a common malignancy among women worldwide. Long non-coding RNAs (lncRNAs) are frequently involved in the pathogenesis of cervical cancer. Therefore, the present study aimed to investigate the potentials of lncRNA799 in cervical cancer. mRNA and protein expression were detected by reverse transcription-quantitative polymerase chain reaction and Western blot analysis, respectively. Cellular functions were assessed using CCK-8, wound healing and transwell analysis. The binding potential of zinc finger E-box-binding homeobox 1 (ZEB1) on the promoter of lncRNA799 was predicted utilizing the JASPAR database, and was then verified by luciferase and chromatin immunoprecipitation (ChIP) assays. Furthermore, the gene interactions were assessed using RNA immunoprecipitation and co-immunoprecipitation assays. The results demonstrated that lncRNA799 was upregulated in cervical cancer cells. However, lncRNA799 deficiency suppressed the proliferation and epithelial-mesenchymal transition of cervical cancer cells. Furthermore, lncRNA799 could interact with eukaryotic translation initiation factor 4A3 to maintain the mRNA stability of transducin (β)-like 1 X-linked receptor 1 (TBL1XR1) and promote the interaction between ZEB1 and TBL1XR1. Additionally, the results showed that ZEB1 could transcriptionally activate lncRNA799. Taken together, the present study suggested that the lncRNA799/TBL1XR1/ZEB1 axis could form a positive feedback loop in cervical cancer and could be, therefore, considered as a potential therapeutic strategy for cervical cancer.

Abstract: The Flipped classroom is an innovative pedagogical model that has been adopted in various colleges across different disciplines. The Flipped classroom allows the students to actively participate and collaborate during in-class activities. The measure of learner's performance, cognitive skills, and behaviour is essential in any teaching-learning process to assess and improvise the curriculum, syllabus, learning methodology, and educational technology. In this research work, various innovative teaching models suitable for Gen Z learners have been experimented with. These models included a virtual classroom, laboratory sessions, and flipped classrooms that were compared with the traditional classroom approach. A new model “CAM-S” is proposed to measure the Cognitive, Affective, and Motivational traits and identify slow learners. Learning analytics using the K-Means clustering algorithm is performed to analyze the behaviour and learning patterns of the learners in these pedagogical models. From the clusters obtained, the students were categorized into 3 different groups based on their performances. The result obtained after the analysis shows that Flipped Classroom has better learner performances when compared with the otherpedagogical methodologies. Additionally, separate questionnaires are also created to obtain feedback from the students about their experiences with the 3 pedagogical techniques used. Even the behavioural models are analyzed using the gaming environment in the flipped classroom. Keywords: Blended Learning, Clustering algorithm, Flipped Classroom, Gamification, Learning Analytics.
POLYETHYLENE GAS PIPELINES: PROBLEMS AND EXPERIENCE OF TECHNICAL DIAGNOSTICS

Published: September 2023

More and more often in various industries, polymer materials are replacing metal structures. The gas industry is no exception, one of the areas of development of which was the introduction of polyethylene pipes to replace traditional steel pipes. This process began more than half a century ago, and according to data at the beginning of 2023, polyethylene pipes account for about 49.5 % of the length of all underground gas pipelines of gas distribution networks.

The main obvious advantage of polyethylene pipes over steel pipes is corrosion resistance, which allows them to be operated without the use of protective anticorrosive coatings and electrochemical protection means. The strength properties of polyethylene pipes allow their operation at gas pressure up to 1.2 MPa, which makes it possible to almost fully meet the needs of the gas distribution sphere. The welding technologies of polyethylene pipes are well developed, standardized and automated.

An important problem for long-term operating polyethylene gas pipelines is the assessment of their technical condition and determination of the residual life. Despite the existing need for work of this kind (for example, in 2022 only in the territory of the Saratov region it was required to carry out technical diagnostics of 8 gas pipelines with a total length of 39.86 km), expert organizations do not have the necessary tool for implementing this task today. Although the mechanism of aging of polyethylene is well known, there are no generally accepted standards for assessing the performance of polyethylene gas pipelines based on a comprehensive accounting of the influence of aging factors that determine their technical condition.

The purpose of this article is to highlight the experience of Giproniigaz JSC in technical diagnostics of polyethylene gas pipelines, as well as to draw the attention of specialists from both the gas industry and academic science to the problem of developing a methodology for technical diagnostics of polyethylene gas pipelines.
ABOUT THE FILLING FACTOR OF PROGRESSIVE CAVITY PUMPS

Published: September 2023

Progressive Cavity Pumps (PCP) are becoming more and more common in various industries.  In the oil and gas sector, PCP are widely used in downhole pumping units for oil production, as well as multiphase pumps for transporting gas-liquid mixtures.  In recent decades, PCP have been widely used in the drilling mud circulation systems in fine cleaning units using centrifuges, as well as in various environmental projects.  At the same time, industrial experience shows that in order to increase the efficiency of the PCP in various technological processes in the oil, construction, food and other industries, it is necessary to clarify some provisions of the theory and practice of using single-screw hydraulic machines in nonstandard operating conditions.  One of these issues, which has not yet been fully reflected in scientific and reference publications, is the study of the process of filling screw working cavities in the case of pumping high-viscosity fluids.

The article discusses the theoretical foundations of modeling the process of filling the PCP and proposes dependencies for determining the filling factor, which allows for a reasonable approach to the choice of geometric and operational parameters of the pump in a wide range of changes in the properties of pumped products.
