Cancer cells and embryonic stem (ES) cells share several biological properties, suggesting that some genes expressed in ES cells may play an important role in cancer cell growth. In this study, we investigated the possible role of zinc finger protein 296 (ZFP296), a transcription factor expressed in ES cells, in cancer development. First, we found that overexpression of Zfp296 in NIH3T3 mouse fibroblasts induced two phenomena indicative of cell transformation: enhanced proliferation under low-serum conditions and anchorage-independent growth. We also found that Zfp296 expression was upregulated in the tumor area of a mouse model of colon carcinogenesis. In addition, the expression levels of ZFP296 in various human cell lines were generally low in normal cells and relatively high in cancer cells. Finally, using a soft agar assay, we found that overexpression of ZFP296 promoted the anchorage-independent growth of cancer cells, while its knockdown had the opposite effect. Overall, these results suggest a possible role of the ES-specific transcription factor ZFP296 in cancer.

Published: January 2024

An increasing number of electric vehicles, hybrids, and synergistic types are adding electronic components, driving up demand for lithium and its derivatives. These chemicals comprise 80% of the worldwide market and come in forms such as carbonate, lithium hydroxide and mineral concentrates. The use of lithium is predicted to surge by 60% in the coming years due to the proliferation of electric vehicles. This demands efficient and rapid deposit detection methods as well as economical and high-resolution exploration equipment. The quantity and geographical distribution of fossil and ore mineral deposits can be easily mapped using hyperspectral photography. Since salt lakes, oceans, and geothermal water hold the majority of the world’s lithium reserves ranging from 70% to 80%, these areas are ideal for the lithium extraction process. In this regard, there is an increase in research targeted at industrial lithium production from water resources. Recycling lithium-ion batteries is an alternative method that can be utilized to increase the production of lithium. Geothermal waters have lower lithium contents than brines and some of the processes are not suitable. Evaporation methods, solvent extraction, membrane technology, nanofiltration and adsorption can all be used to extract lithium from liquid media. Thus, lithium extraction from aqueous solutions was the focus of this review article, which aimed to provide straightforward technical solutions, low costs, decreased environmental impact and excellent selectivity for the lithium industry.

Published: January 2024

Regioselective synthesis of a series of 1-aryl 1,2,3-triazoles-4-methoxy methyl-3-quinoline-2-morpholine employing click reaction is presented. Highly selective and efficient copper(I)-catalyzed 1,3-dipolar cycloaddition between 2-morpholinoquinoline-3-methyl propargyl ether and various aryl azides 5a-j yielded the title compounds 6a-j in 71% to 85%. The structure of all the novel 1,2,3-triazoles was characterized by 1H NMR, 13C NMR, IR and mass spectral analysis. The analogues were evaluated for their in vitro anticancer activity against MDA-MB-231 cell line. All the synthesized compounds were proven to have anticancer activity in comparison to reference drug doxorubicin. Especially, chloro and fluoro substituent compounds demonstrated potent activity with IC50 values of 17.20 ± 0.09 µM and 23.56 ± 0.09 µM, which proved their efficacy and could be further studied for the development of novel chemotherapeutics.
Retextualização no ensino-ap(p)rendizagem
Authors: Pinchemel-Amorim Marina Martins , Melo Pereira Márcia Helena de
Published: January 2024

Retextualização é a produção de um novo texto a partir de um texto anterior (ou um conjunto deles), sendo observada em atividades cotidianas ou com propósito de ensino-aprendizagem. Marcuschi (2010a) apresenta quatro tipos de retextualização, no continuum fala-escrita. Neste artigo, investiga-se a atividade de retextualização do tipo hipertexto-hipertexto, que ocorre no ambiente digital. Para tanto, foram analisados dados processuais de uma retextualização hipertextual, coletados enquanto duas estudantes do Ensino Médio elaboravam, conjuntamente, publicações de Instagram. Os dados foram captados em vídeo e áudio e, posteriormente, transcritos. O corpus consiste em: (i) transcrição do diálogo mantido pela dupla enquanto retextualizava; (ii) transcrição de entrevista semiestruturada gravada em áudio com as estudantes; (iii) duas publicações de Instagram elaboradas pelas alunas. A partir dos dados, o processo de construção dos hipertextos foi remontado, descrevendo as sete tarefas de produção da retextualização propostas por Dell’Isola (2007). A investigação apontou que a categoria hipertexto-hipertexto apresenta peculiaridades em seu processo de concepção e produção. Dessa forma, faz-se necessário abordar a retextualização hipertextual de forma diferenciada, o que justifica um quinto tipo de retextualização, em adição aos quatro tipos apresentados por Marcuschi (2010a).
A aprendizagem criativa do sujeito: um estudo à luz da Didática Desenvolvimental e da Teoria da Subjetividade
Authors: Carcanholo Flávia Pimenta de Souza
Published: January 2024

O presente resumo de tese aborda uma discussão acerca da aprendizagem do sujeito enquanto uma produção criativa, sobre a base dos fundamentos teóricos da Didática Desenvolvimental, dos estudos decorrentes do sistema didático Elkonin-Davidov-Repkin e da Teoria da Subjetividade, realizada por F. González Rey. Parte-se do pressuposto que para aprender é preciso considerar o sujeito desse processo, sendo este o protagonista nesta ação. Requer, ainda, conceber as condições históricas, culturais, sociais e subjetivas oriundas do processo de aprender. Neste sentido, direciona-se à hipótese que todo indivíduo só aprende quando emerge como sujeito, sendo essa aprendizagem fruto da sua atividade criativa, em unidade simbólico-emocional. Dessa hipótese, origina-se a problemática da pesquisa sobre a aprendizagem humana ser sempre um ato de produção criativa; se a criança é sujeito de sua aprendizagem e se só aprende o sujeito. O objetivo geral da pesquisa esteve direcionado a investigar a produção da aprendizagem criativa na Atividade de Estudo, vinculada à área da matemática, por meio da metodologia do estudo de caso com crianças do primeiro ano do ensino fundamental, considerando a subjetividade. Utilizou-se dos princípios da Metodologia Construtivo Interpretativa para a construção e interpretação da aprendizagem, na elaboração e análise de indicadores do estudo de caso e construções hipotéticas do processo de aprender sob o ponto de vista da didática.

No museu e na Avenida, Leandro Vieira “de fora”
Authors: Freitas Lima Pedro Ernesto
Published: January 2024

Tomando como objeto de interesse o trabalho “Bandeira brasileira” (2019-2021) realizada pelo carnavalesco Leandro Vieira – atuante em escolas de samba do Rio de Janeiro –, e mais especificamente sua exibição e posterior incorporação ao acervo do MAM-Rio, discutiremos problemáticas e estratégias presentes em recentes eventos que promovem trânsitos entre o chamado “popular” e a arte contemporânea institucionalizada. A partir de uma perspectiva decolonial, discutiremos como esses trânsitos entre carnavalescos e espaços institucionais da arte via curadoria e exposições, quando esses agentes e suas produções são assimiladas enquanto “arte contemporânea”, tensionam e reconfiguram as instituições artísticas e os modos como produzem narrativas, sentidos e legitimação. Para isso, contextualizaremos o caso de Vieira em relação a outros carnavalescos que também foram alvo de interesse de agentes e instituições artísticas diversos, e faremos breves considerações sobre o ofício do carnavalesco, suas práticas e saberes específicos, referenciado nas pesquisas de Helenise Monteiro Magalhães e Maria Laura Viveiros de Castro Cavalcanti.
The effect of perceived quality and value on express delivery services trust during pandemic Covid 19
Authors: Firdaus Fika Fahmi , Sutarso Yudi
Published: January 2024

During the Covid-19 pandemic, public mobility restriction policies were implemented to prevent the new coronavirus spread. In this period, express delivery services have played an essential role in transporting packets between areas supporting everyday life. This study examines the role of perceived quality and value on brand trust in express delivery services, namely J&T Express Indonesia, the top brand courier service in Indonesia. The researchers employed a purposive sampling and involve 162 respondents of the customer. The study collected data through questionnaires and analyzed using the Partial Least Square-Structural Equation Model. The critical finding showed that perceived quality (excitement, enjoyment, bonding with, and reliability) positively affected the perceived value and brand trust. The other result shows that perceived value (good value, acceptable, good deal, competitive, like, feel-good) affected brand trust. The study’s implication suggests the strategy for express delivery services to enhance perceived quality and value for further increasing customer trust.
Research on Paradox in Strategic Management: a Bibliometric Analysis from 2000 to 2021
Authors: Thoha Ahmad Faiz Khudlari
Published: January 2024

The sustainability of strategic management processes demands the accommodation of different expectations. The idea of paradox encourages organizational leaders to manage conflicts by accommodating the competing impulses. In the past quarter century, the theory of paradox and its continuous evolution has evolved dramatically, presenting excellent opportunities amid the speed of technological progress, reduced resources, and diverse customer expectations. The study comprehensively analyzes paradoxical concepts in current strategic management research and explores future related literature development opportunities. The bibliometric analysis method was used in this study to map and evaluate trends of paradox in strategic management domains using a statistical approach to 633 articles from Scopus. The results show that paradox in strategic management has implications related to servitization, open innovation, organizational change, ambidexterity, knowledge sharing, diversity, value creation, corporate sustainability, dynamic capabilities, and social entrepreneurship. The results of this study can guide the researchers to develop paradoxical research in the field of strategic management in the future.

Published: January 2024

This study aims to discuss the causal analysis of government revenues and expenditures in Indonesia in light of the fact that Indonesian fiscal policy significantly relies on government finance. Therefore, it can lead to fragile macroeconomic conditions. In addition, to illustrate this occurrence, the researchers used Granger causality method on data from 1971 to 2021 provided by the World Bank. This paper's findings indicate that in Indonesia, the long run or equilibrium relationship between government revenue and government expenditure goes from government expenditure to government revenue. In addition, this conclusion demonstrates that government expenditures affect government revenue.
The Effect of Value-Added Tax Policy on Per Capita Income and Inequality in Indonesia
Authors: Asri Sekar Ayu Cahyaning , Suseno Deky Aji
Published: January 2024

The implementation of value-added tax (VAT) policy holds significant sway over state revenue. This study delves into the impact of value-added tax on economic growth and inequality within Indonesia. Panel data spanning from 2017 to 2021, encompassing 34 provinces, was scrutinized using the panel vector error correction model alongside the Sobel test. The study's findings reveal that while VAT directly affects per capita income, it exerts no discernible influence on inequality, either directly or indirectly. When subjected to the PVECM test, VAT shows no long-term impact on income. In contrast, domestic investment and the democracy index exhibit a positive and noteworthy effect on income levels. Notably, VAT and foreign investment do not demonstrably impact inequality. In the long run, it is per capita income, the democracy index, and domestic investment that bear influence. In the short term, however, none of these variables significantly affect inequality. It is worth mentioning that per capita income experiences a positive and substantial influence from the democracy index and domestic investment. This research furnishes policymakers with valuable insights to guide revenue management and allocation, thereby advancing economic development and addressing prevailing social challenges.
Poor Performance of Small, Medium, and Micro Enterprises in South Africa: What has Race and Apartheid Got to Do with it?
Authors: Makwara Tendai , Sibanda Lucky , Iwu Chux Gervase
Published: January 2024

Small, medium, and micro enterprises (SMMEs) are expected to contribute significantly to South Africaâ€™s socioeconomic development. Despite the various private and public institutional agencies in place to bolster the role of SMMEs, these SMMEs continue to perform poorly. The poor performance of SMMEs has been linked to race and apartheid. Through a literature review, this study explored this attribution of SMMEsâ€™ poor performance to race and apartheid, considering that many argue that the apartheid legacy is the root of many challenges encountered by SMMEs. The results are, however, ambivalent. They suggest that, although apartheid and race remain critical issues in explaining some existing structural challenges that SMMEs encounter, their effects may have been superseded by other post-apartheid issues that undermine SMMEsâ€™ performance. Specifically, apart from continuing influences of apartheid-era challenges such as race-based barriers to markets and access to financial support, present-day issues such as corruption, bad governance, ill-conceived business strategies, and infrastructure challenges negatively influence the performance of SMMEs. Addressing these multifaceted issues requires coordinated efforts from the government, the private sector, and other stakeholders to create a conducive environment for SMMEsâ€™ growth and success. We, therefore, conclude that the causes of the poor performance of SMMEs in South Africa stretch beyond race and apartheid and call for an exhaustive analysis of broader issues that undermine SMMEsâ€™ performance in South Africa.
Financial Well-Being Model for Bank Employees: the Role of Financial Behavior as a Mediator
Authors: Setiawan Hendro , Iramani Rr
Published: January 2024

The aim of this study is to investigate the factors influencing the financial well-being of Bank Jatim employees in Indonesia. These factors encompass financial knowledge, financial socialization, internal locus of control, lifestyle, and current financial stress. Additionally, the study delves into the role of financial behavior as a mediator in this model of financial well-being. The respondents in this study are permanent employees of Bank Jatim, Indonesia, selected through purposive sampling. The findings reveal that financial knowledge, financial socialization, and current financial stress directly impact financial well-being. Internal locus of control affects financial well-being both directly and indirectly, mediated by financial behavior. However, financial behavior doesn't serve as a mediator for the influence of lifestyle on the financial well-being of bank employees. Furthermore, the results do not provide sufficient evidence for financial behavior mediating the effects of other determinant variables. For the company, this implies that enhancing the financial well-being of bank employees should involve efforts to augment their financial knowledge, promote financial socialization, and encourage a composed approach to managing their financial situations. As for bank employees, achieving financial well-being necessitates maintaining an internal locus of control and exhibiting prudent financial management behaviors.

Once known, always known. Turn-final sai in North-East regional Italian
Authors: Biasio Marco , Del Fante Dario
Published: January 2024

This paper focuses on the structural and functional properties of a positionally flexible verb-based discourse marker, sai (lit. ‘you know’), which in its turn-final position is a conversational hallmark of the regional variety of Standard Italian spoken in and around Padova, in the north-eastern region of Veneto. Drawing from a series of distributional and scopal constraints (including the interaction with other turn-initial and turn-final verb-based discourse markers, vocative phrases, verum focus, and the negative polarity item mica), it is claimed that both turn-initial and turn-final sai are best analyzed as intersubjectively-oriented Common Ground management operators (Repp, Sophie. 2013. Common ground management: Modal particles, illocutionary negation and verum. In Daniel Gutzmann & Hans-Martin Gärtner (eds.), Beyond expressives: explorations in use-conditional meaning (Current Research in the Semantics/Pragmatics Interface 28), 231–274. Leiden & Boston: Brill) activated by Speaker’s salient presuppositional biases of opposite polarity. Syntactically, within Interactional Spine Hypothesis (Wiltschko, Martina. 2021. The grammar of interactional language. Cambridge: Cambridge University Press), it is shown how both turn-initial and turn-final sai are base-generated above the C system, in the specifier position of the lower (Speaker-oriented) field of the so-called GroundP, and then moved up to the specifier position of the higher (Addressee-oriented) GroundP; additionally, the mild-rising intonational contour associated with turn-final sai is claimed to perform a call on the Addressee, which activates the corresponding Resp(onse)P above GroundP. These results contribute to the available literature on the micropragmatic process of construction and negotiation of context-bound evidential meanings, also as a tool to foster manipulative processes.
Verschuldete Bauern, Pächter oder Erntearbeiter? Noch einmal zur Frage: Wer waren die „hektḗmoroi“?
Authors: Schmitz Winfried
Published: January 2024

In vorsolonischer Zeit war nach Angaben Plutarchs und der aristotelischen „Athenaion politeia“ ein großer Teil der Bevölkerung Attikas von reichen Landbesitzern abhängig. Darlehensgeber konnten Schuldner, die ihre Schulden nicht zurückzahlen konnten, ergreifen und mit sich führen. Sie ließen sie auf ihren Feldern arbeiten oder verkauften sie in die Sklaverei. Solon selbst beklagte in seinen Elegien diese Konsequenzen, die rechtens waren, da sie dem archaischen Schuldrecht entsprachen. Der Vergleich mit der römischen Noxalhaftung zeigt, dass so wie in Rom auch im archaischen Athen eine Person, die einen Vertrag gebrochen oder eine Schädigung verursacht hatte, dem Geschädigten zu übergeben war. Durch den Vergleich mit der römischen Noxalhaftung lässt sich die Form der Schuldknechtschaft und der Schuldsklaverei im frühen Athen besser verstehen. Von diesen Personen zu unterscheiden sind aber die hektḗmoroi, die frei blieben; als Angehörige der unterbäuerlichen Schicht waren sie auf einen Zuverdienst angewiesen. Für Erntearbeiten erhielten sie ein Sechstel der geernteten Produkte, einen hekteús pro geerntetem médimnos. Da sie lediglich „Erntepächter“ waren, auf dem Feld also nicht das ganze Jahr über wirtschafteten, war ein Sechstel angemessen und reichte, um die eigenen Erträge so weit zu steigern, dass sie sich und ihre Familien ernähren konnten. Die Annahme, Solon habe ein Exportverbot aller landwirtschaftlichen Produkte gesetzlich festgeschrieben, beruht wahrscheinlich auf einem falschen Textverständnis; tatsächlich bezog sich das Gesetz auf Kontrakte über Erntearbeiten auf heiligem Land und kann als Beleg dafür gewertet werden, dass solche Ernteverträge in archaischer Zeit verbreitet waren.
Determination of the time-dependent effective ion collision frequency from an integral observation
Authors: Cao Kai , Lesnic Daniel
Published: January 2024

Identification of physical properties of materials is very important because they are in general unknown.
Furthermore, their direct experimental measurement could be costly and inaccurate. In such a situation, a cheap and efficient alternative is to mathematically formulate an inverse, but difficult, problem that can be solved, in general, numerically; the challenge being that the problem is, in general, nonlinear and ill-posed. In this paper, the reconstruction of a lower-order unknown time-dependent coefficient in a Cahn–Hilliard-type fourth-order equation from an additional integral observation, which has application to characterizing the nonlinear saturation of the collisional trapped-ion mode in a tokamak, is investigated. The local existence and uniqueness of the solution to such inverse problem is established by utilizing the Rothe method. Moreover, the continuous dependence of the unknown coefficient upon the measured data is derived. Next, the Tikhonov regularization method is applied to recover the unknown coefficient from noisy measurements.
The stability estimate of the minimizer is derived by investigating an auxiliary linear fourth-order inverse source problem. Henceforth, the variational source condition can be verified.
Then the convergence rate is obtained under such source condition.
Predictors of planned home birth before and during the COVID-19 pandemic
Authors: Crockett Allison K. , Laden Bethany F. , Tumin Dmitry , Whiteside James L.
Published: January 2024

Objectives

To determine how demographic and clinical predictors of home birth have changed since the onset of the COVID-19 pandemic in the US.

Methods

Using National Vital Statistics birth certificate data, a retrospective population-based cohort study was performed with planned home births and hospital births among women age ≥18 years during calendar years 2019 (pre-pandemic) and 2021 (pandemic-era). Birth location (planned home birth vs. hospital birth) was analyzed using univariate and multivariable logistic regression, systematically examining the interaction of each demographic and clinical covariate with study year.

Results

After exclusions, a total of 6,087,768 birth records were retained for analysis, with the proportion of home births increasing from 0.82 % in 2019 to 1.24 % in 2021 (p<0.001). In the final multivariable logistic regression model of planned home birth, five demographic variables retained a statistically significant interaction with year: race and ethnicity, age, educational attainment, parity, and WIC participation. In each case, demographic differences between those having planned home births and hospital births became smaller (odds ratios closer to 1) in 2021 compared to 2019.

Conclusions

Planned home births increased by more than 50 % during the pandemic, with greater socioeconomic diversity in the pandemic-era home birth cohort. The presence of clinical risk factors remained a strong predictor of hospital birth, with no evidence that pandemic-era home births had a higher clinical risk profile as compared to the pre-pandemic period.
Anti-Criterialism Does Not Result in an Unacceptable Consequence
Authors: Zhan Xinyi
Published: January 2024

Anti-criterialists argue that there are no criteria that ensure personal persistence. However, this perspective is criticized for resulting in an unacceptable consequence that undermines our intuitions, daily beliefs, and direct introspective awareness of personal persistence. I defend anti-criterialism by responding to this objection and arguing that none of these aspects are undermined by anti-criterialism. The flawed objection against anti-criterialism reveals the excessive ambition of criterialism in seeking criteria for personal persistence with metaphysical necessity, which goes beyond our abilities and needs. As beings living in the actual world, we are not able to consider what happens to personal persistence in remote possible worlds. Moreover, to judge whether a person persists or not in daily life, we do not need a criterion that ensures personal persistence in all situations. Anti-criterialism acknowledges the complexity and variability of personal persistence and offers a more realistic and practical approach to understanding personal identity.
Comprehensive Examination of Version Number Attacks in IoT Networks: Nodes Hyperactivity as Specific Criterion
Authors: Belkhira Hichem Sid Ahmed , Belkheir Mohammed , Rouissat Mehdi , Mokaddem Allel , Lorenz Pascal , Boukhobza Mohamed Achraf , Salmi Abdelhamid , Kouar Ahmed
Published: January 2024

The security landscape of Internet of Things (IoT) networks continues to draw significant attention from recent networks; the Version Number Attack (VNA) stands out as a prominent threat to IoT network resources. Routing Protocol for Low-Power and Lossy Network structures low-power and lossy networks through one or more Destination Oriented Directed Acyclic Graphs (DODAGs). Each DODAG is assigned a version number, serving the purpose of ensuring the existence of loop-free paths to the root node. In the event of any inconsistency detected by the root node, the version number is incremented, triggering a global repair process and the reconstruction of the Directed Acyclic Graph. A potential security concern arises when a malicious node advertises a false version number in its control message, compelling the initiation of a global repair process. This study conducts a comprehensive analysis of the VNA’s impact, considering various parameters that have not been explored in previous research articles. These parameters include an examination of the additional forwarding tasks introduced by the attack and an exploration of factors contributing to node hyperactivity (such as loops, local and global repairs, etc.). The article delves into the specific control messages that result in the detrimental effects of the attack, offering a detailed analysis of control overhead, energy consumption, Packet Delivery Ratio, and latency. The obtained results show that the DAO (Destination Advertisement Object) messages dominate the total control overhead and are the main contributor to the total consumer energy, where the closest the malicious node to the sink the more damaging is the attack.
The influences of proficiency and gender on Uyghur-Mandarin children’s advice-giving
Authors: Peng Yuchen , Ren Wei , Wu Ruilin
Published: January 2024

Mandarin Chinese, as the national lingua franca in China, has gained increasing importance in bilingual education in ethnic minority areas in the country. However, little research has explored ethnic minority children’s pragmatic competence. Therefore, this study investigates ethnic Uyghur children’s written pragmatic performance of advice-giving through a brief note in Mandarin and the possible effects of proficiency and gender on their advice-giving. Data were collected from 300 ethnic Uyghur children across three proficiency levels with a balanced gender split. In addition, 100 Han children were also recruited as a comparison group. The advice produced by the children was coded in terms of speech act strategies and supportive moves. The findings showed that the Uyghur children with higher proficiency provided more reasons and fewer affective expressions when giving advice than the two lower proficiency groups, reflecting the performance of the Han children. On the other hand, the results also revealed gender differences in certain advice-giving strategies and supportive moves. The study discusses the findings in relation to national lingua franca and second language pragmatics. Some pedagogical implications for multilingual education in ethnic minority areas are also provided.

Published: January 2024

Con el propósito de conocer la factibilidad de usos alternativos de los sedimentos acumulados en la presa La Esperanza, en el municipio de Guanajuato, estos fueron sometidos a análisis químicos cuantitativos. Se encontró que los contenidos de metales preciosos y tierras raras hacen factible el aprovechamiento económico de los sedimentos. Adicionalmente, los sedimentos, una vez tamizados y clasificados, se usaron para producir ladrillos. Los resultados de pruebas de resistencia en compresión, porosidad y adsorción se compararon con los de ladrillos producidos usando arcillas de comunidades de los municipios de Irapuato y Abasolo. No se encontraron diferencias estadísticamente significativas en los resultados de los ladrillos producidos con los tres tipos de arcillas usadas; por lo tanto, los sedimentos podrían ser usados para producir ladrillos. De esta forma, de los sedimentos se pueden extraer metales con alto valor comercial, y una vez procesados se pueden usar para hacer ladrillos usables en construcción.

Purpose: individuals with intellectual disability (ID) often experience challenges related to low levels of physical fitness, impacting both their physical and mental well-being. This study aims to evaluate the pulmonary function of children with ID and explore the effect of yoga practices on pulmonary function among the participants with ID. Material & Methods: the study was an assessor-blinded, randomised, controlled study. Participants clinically diagnosed with intellectual disability (ID) were randomly assigned to either yoga intervention or no intervention for a duration of 6 months. Pulmonary function test was assessed at baseline and after 6 months of intervention using a Helios 401 device. Results: in this study, a total of 56 adult participants of both sexes with intellectual disabilities (ID) were initially enrolled (n=56). Following the intervention, the final sample size was 48 participants. Notably, the participants in the yoga group demonstrated a statistically significant (p<0.05) improvement in pulmonary function parameters when compared to the control group. These findings suggest a positive impact of the yoga intervention on pulmonary function, highlighting its potential as a beneficial therapeutic approach for individuals with intellectual disabilities. The observed improvements underscore the significance of incorporating yoga into interventions aimed at enhancing respiratory well-being in this population. Conclusion: in conclusion, this randomized controlled study offers valuable insights into the effects of various types of yoga practice on the pulmonary function of healthy young adults with intellectual disabilities. The positive outcomes observed underscore the potential of yoga as an effective intervention for enhancing pulmonary function in individuals with intellectual disabilities. These findings contribute to the growing body of evidence supporting the integration of yoga into interventions aimed at promoting respiratory well-being in this population. Further research and exploration of specific yoga practices may provide additional tailored approaches for optimizing the respiratory health of individuals with intellectual disabilities.

Abstract Buchholzia coriacea seeds has been reported to have various medicinal properties. This study evaluates the effect of the aqueous extract of Buchholzia coriacea seed (wonderful kola), on Aluminium chloride induced liver toxicity in adult male Wistar rats. 24 rats weighing between 90g-200g were divided into five groups. Group A- (the control group) received water and animal chow. Group B received 200mg/kg of AlCl3 only, Group C received 200mg/kg body weight of aqueous extract Buchholzia coriacea only. Group D received 50mg/kg body weight body weight (Low Dose) of aqueous extract Buchholzia coriacea and (200mg/kg) AlCl3 . Group E received 250mg/kg body weight (High Dose) of aqueous extract of Buchholzia coriacea and (200mg/kg) AlCl3 . The animals were sacrificed, the liver was excised and processed for routine paraffin sections at 5micromes thick. Sections were stained with Haematoxylin and Eosin to demonstrate histoarchitecture. Biochemical analysis was also carried out to determine the effects on liver antioxidant enzymes. Histological assessment showed narrowed central vein, degeneration of hepatocytes and distortion of sinusoids in the AlCl3 alone treated groups. The histoarchitecture of the liver in the other groups showed improvement especially in Group E (High Dose of B. coriacea) and Group C (B. coriacea extract only). The biochemical analysis on the other hand showed significantly reduced activities in GSH, SOD, CAT and significantly increased level of MDA in the Alcl3 only group. In the other groups, MDA levels reduced, GSH, SOD and CAT also increased enzymatic activities following the administration of B. coriacea. The study concludes that Buchholzia coriacea seed extract plays a role in protecting liver from Alcl3 toxicity

Este trabalho traz o relato e as conclusões de uma pesquisa desenvolvida ao longo de cerca de três anos com o objetivo de proporcionar um processo lúdico de aprendizagem de língua espanhola a alunos dos anos finais do Ensino Fundamental de uma escola pública. Partindo dos conceitos de Homo Ludens, de Huizinga (2000), de aprendizagem ergódica, de Leffa e Beviláqua (2019), e de inserção das tecnologias digitais no ensino de línguas, em especial os videojogos, conforme proposto por autores como Leffa e Pinto (2014), propusemo-nos a desenvolver uma oficina de games com os estudantes, a fim de que eles aprendessem a criar seus próprios jogos e pudessem utilizar a língua espanhola não como fim, mas como meio para construir seus produtos. Para tanto, desenvolvemos, primeiramente, um jogo na plataforma Escape Factory, que serviu de base e inspiração para os alunos. Essa pesquisa, de abordagem qualitativa, foi realizada sob os pressupostos metodológicos do Design-Based Research, que prevê uma série de fases no desenvolvimento de produtos com fins educacionais, fases essas que se desenvolvem em ciclos iterativos, o que implica contínuas avaliações e reformulações. A partir do jogo-modelo e da oficina de criação, os alunos desenvolveram seus próprios games digitais em espanhol. Com as anotações realizadas em diário de bordo ao longo do processo, além dos questionários respondidos pelos alunos, podemos afirmar, ainda que novos estudos sejam necessários, que a aprendizagem de língua adicional por meio do desenvolvimento de jogos pode ser significativa, motivadora e, principalmente, efetiva.

Por una recuperación de la teología de las realidades terrenas
Authors: Tagliapietra Claudio
Published: January 2024

Después de casi sesenta años, la teología de las realidades terrenas contenida en la primera parte de Gaudium et spes sigue siendo una prometedora fuente de reflexión. Como perspectiva que sintetiza la relación entre Dios y el mundo, recuerda al hombre su identidad misionera y el mandato de transformar el mundo. Sin embargo, el interés por esta perspectiva parece haber disminuido pocos años después del Concilio. Este ensayo examina el contenido de esta teología, busca destacar las posibles razones que han obstaculizado su desarrollo e identifica las condiciones para su recuperación.
Mathematical modelling of eye cornea deformation under external pressure
Authors:   Moscow State University, Moiseeva Irina , Stein Alexander ,   Moscow State University
Published: January 2024

The deformation of the eyeball under the action of external pressure applied to the cornea in a limited area, for example, as a result of loading with an air jet, is considered. The cornea is modeled by a homogeneous, isotropic, momentless surface and, in the general case, is considered to be linearly Voigt-type viscoelastic. Its elastic properties are determined by the quadratic dependence of the strain energy on the components of the strain tensor, and viscous properties by the quadratic dissipative function of the strain rates. The scleral region is described by the differential relationship between the scleral volume and intraocular pressure. The process of slow deformation is considered in detail, when the derivatives of the deformation characteristics with respect to time can be neglected in the constitutive relations. It is shown that, at a certain external pressure, a section is formed in the central region of the zone of its influence, which can be considered to be flat with high accuracy. From the external pressure at which this zone occurs, the true intraocular pressure, i.e., pressure in an unloaded eye, can be determined with good accuracy. The relationship between these pressures is weakly affected by the elastic properties of both the cornea and the scleral region. In the area of external pressures corresponding to “flattening”, the rate of subsidence of the corneal apex at uniformly increasing external pressure changes. Possible generalizations of the model and problem formulation are discussed.

The aim of the study was biomechanical modeling of the development and influence of thoracic aortic aneurysm on the hemodynamics of the vessel. Aortic aneurysm is an irreversible expansion of the aorta and is one of the diseases of the cardiovascular system with a high fatal outcome. Biomechanical modeling included: setting the task, building a virtual model of the object under study, setting boundary and initial conditions and properties of materials, also assessment the results of a numerical experiment based on the physiological characteristics of the object. Two three-dimensional virtual models of the thoracic aorta were constructed on the basis of computed tomographic angiography of a real patient: with an aneurysm of the ascending division and after prosthetics. To analyze the development of pathology, were created additional virtual models with different degrees of aneurismal expansion. The calculation is carried out taking into account the parameters characterizing the work of the cardiovascular system (blood pressure value, dynamic viscosity and blood density). The analysis of the results showed a change in the character of blood flow, the formation of region of blood stagnation in the aneurysm zone. It was revealed that with the increase in the geometric dimensions of the pathology there is a drop in the blood flow rate and an increase in the flow pressure values in the aneurysm. Asymmetric distribution of pressure values on the inner surface of the aorta, triggered by the displacement of the flow velocity vector relative to the axis of the blood vessel, can to incite further development of an aneurysm.
