ABSTRACT Sweet potato is a vital food root, rich in vitamins, minerals, and bioactive compounds. Genotypes that meet these nutritional demands are essential to combat nutrient deficiencies and promote human health. Thus, it presupposes the hypothesis that sweet potato genotypes differ in physicochemical quality and bioactive compounds when evaluated under the same environmental conditions. Thus, this study aims to evaluate the physicochemical quality and bioactive compounds in genotypes of orange-fleshed sweet potato. The experiment was conducted from April 2022 to August 2022 in the experimental area of Agronomic Engineering, located at the Academic Unit Specialized in Agricultural Sciences (UAECA) - UFRN, in Macaíba, RN, Brazil. The treatments were composed of eight genotypes, being two cultivars (BRS Amélia and Beauregard) and six accessions (Macaíba I, Macaíba II, Macaíba III, Macaíba IV, Ceará-Mirim, and Natal I) of orange-fleshed sweet potato from the UAECA teaching collection. After harvest, the following characteristics were evaluated: firmness, elasticity, hydrogen potential (pH), titratable acidity (TA), soluble solids (SS), ratio (SS/TA), Vitamin C, and the bioactive compounds: anthocyanins, flavonoids, and total carotenoids. The orange-fleshed sweet potato genotypes showed distinct characteristics for the physicochemical variables and the bioactive compounds. Due to increased pulp pH, anthocyanins were reduced in the Ceará-Mirim, Macaíba III, and Macaíba IV genotypes. The Macaíba II and Natal I genotypes stood out regarding the SS/TA ratio, flavonoids, and anthocyanins. In contrast, the Macaíba III genotype had the highest carotenoid content and great bioactive potential.
Tissue investments related to water absorption and retention in Bromeliaceae: exploring variations in CAM metabolism expressing between dry and rainy seasons

Published: December 2024

Abstract Structure and function are strongly related in bromeliad leaves. Some species do not develop tank rosettes and must rely on other structural and physiological attributes to deal with environmental stressors. Three species of Bromeliaceae without tanks were compared according to their leaf structure (anatomy and pectin composition), water retention abilities, and photosynthetic pathway expressions. Tillandsia stricta is an epiphyte, shaded by the canopy in a riparian forest, T. usneoides occurs on palm trees in an adjacent opened area, while Dyckia minarum is terrestrial and exposed to high light intensities in rupestrian fields. Despite limiting light and/or water conditions in each habitat, these species occur in adjacent areas. While they express CAM metabolism, D. minarum demonstrated more expressive acidity. Its greater investments in tissues related to water absorption and retention may reflect its high exposure to sunlight, poor nutrient availability for growth, and CAM expression. Tillandsia usneoides modifies its water-storing capacity between seasons, a property possibly associated with the presence of high methyl-esterified HGs in its cell walls. The higher succulence and relative water content during the rainy season may stimulate photosynthetic activity and maximize CAM expression.

Abstract Seasonally Dry Tropical Forests experience pronounced precipitation seasonality, intense solar radiation, and high temperatures, which often translate into high levels of deciduousness during the dry season. In these environments, deciduous species coexist with some evergreen species that are able to maintain their canopy leaves throughout the dry season. To understand the strategies behind this behavior, we analyzed leaf anatomical traits of 13 individuals of Sarcomphalus joazeiro during both the wet and dry seasons in a seasonal deciduous forest. We hypothesized that wet-season leaves would differ anatomically and functionally from dry-season leaves. Specifically, we expected wet-season leaves to show a more acquisitive resource-use strategy compared to dry-season leaves, which we expected to be more conservative. We assessed the effects of season and climatic variables on 25 leaf anatomical traits using generalized linear mixed models (LMM). Leaf traits varied between the wet and dry seasons and interacted with climatic variables, which together suggest that S. joazeiro produces season-specific leaf cohorts. This adaptation allows the species to adjust to the contrasting conditions of light intensity, temperature, and evaporative demand in each season.

Published: December 2024

Abstract Senecio carbonellii, an endemic plant of Colombia, is classified as critically endangered in the wetlands of Bogotá D. C. This study aims to determine the desiccation tolerance and longevity of S. carbonellii seeds and evaluate the effect of flooding on seed germination and plant growth to provide information for the development of conservation strategies for the species. For this purpose, we assessed the germination, viability (using tetrazolium testing), and longevity of desiccated seeds compared to seeds with initial moisture. We also evaluated the effect of flooding on the emergence and growth of seedlings and plants under nursery conditions. Our findings indicated that the seed viability and germination percentages were significantly higher in the seeds with initial moisture compared to desiccated seeds. However, we observed that viability is maintained even after storing the seeds for more than two years, indicating that the seeds partially tolerate desiccation and that they are likely to have an intermediate storage behavior. Furthermore, flooding depth reduced the stem number, diameter, and length of plants. The results revealed that flooding negatively affects emergence and growth in the nursery.

Empresas do crime: a articulação dos mercados do jogo do bicho para uma economia legal e ilegal
Authors: Labronici Rômulo Bulgarelli , Rodrigues Eduardo de Oliveira
Published: December 2024

Resumo No imaginário do jogo clandestino, os banqueiros do jogo do bicho representam a face da política institucional dos “donos” do jogo e sua representação social está além de um simples marginal ou fora da lei. Sua força não advém exclusivamente do indivíduo, mas das redes em que se encontram inseridos e de seu grande poder econômico que lhes garante uma cobertura política/policial para exercer suas atividades. Assim, buscamos observar como a gestão dos negócios de um banqueiro do bicho, a partir deste sustentáculo econômico e político-policial, tende a ser diversificada de modo a usufruir das potencialidades que o dinheiro do jogo pode proporcionar. Aqui, buscamos analisar o jogo com o intuito de compreender em que circunstâncias a economia das apostas possibilita, alimenta e necessita da composição de outros mercados para o seu funcionamento pleno. Para tal, serão analisados dados etnográficos, notícias de jornais e processos penais que contribuam para a demonstração de como o poder e influência político-econômica do bicho possibilita que novos mercados sejam explorados e fortalecidos. Apontando para a existência de atores-chave dentro das redes constituídas enquanto “intermediadores” em sua operação com contraventores, policiais, curadores de arte e diversos outros.

Published: December 2024

Abstract The study of the effects of cellulosic materials as additives in matrices based on mineral binders is essential for the development of high-performance and more durable construction materials. In this context, the present research aims to propose composite systems incorporating cellulose microparticles and microfibers into cementitious matrices. The proposed systems were developed using CP V ARI cement, with cellulose microfiber (FC) contents of 0.5%, 1%, and 1.5%, along with crystalline microcellulose (MCC) contents of 0.4%, 0.6%, and 0.8%. The impact of cellulose microfiber and crystalline microcellulose on compressive strength, flexural tensile strength, mineralogy, and microstructure of cementitious composites was evaluated. The gradual increase in the combined additions of cellulose microfiber and crystalline microcellulose led to a reduction in mechanical properties. The diffraction patterns of the FC-MCC cellulose-added composites were similar to those of Portland cement composites without additives. The combinations of FC 0.5-MCC 0.4, FC 1.0-MCC 0.4, and FC 0.5-MCC 0.6 contents promoted a higher degree of hydration, resulting in superior compressive strength performance compared to cementitious composites without these materials.

Reconceptualising Curriculum in a new era of Welsh Education
Authors: Smith Kevin
Published: December 2024

The new curriculum framework for Wales offers educators an approach to curriculum work that is a radical departure from the previous national curriculum introduced in 1988. One feature of the new curriculum framework is its emphasis on experience. However, there is little support for theoretical considerations of experience offered by the Welsh Government in their guidance for teachers. This article proposes that reconceptualist approaches to curriculum theory and theorising can potentially address this shortcoming. The reconceptualisation of curriculum shifts the focus from traditional perspectives to understanding curriculum as ‘lived experience’ (Pinar 2019). Additionally, with the introduction of the method of currere, Pinar (1975) offers a method through which educators can analyse and interpret how their educational experiences influence and shape their educational values, practices and identities, as well as how they come to ‘understand curriculum’ (Pinar et al., 2008). In this article, I discuss the origins and aims of the reconceptualist movement in the context of the new curriculum for Wales and argue that such approaches to understanding curriculum can increase teachers’ capacity for educational research, enhance their curricular understanding, and strengthen articulations of their educational and professional voice.

Ethics of Care in Collaborative Art Practices
Authors: Aldouby-Efraim Danielle Ayelet
Published: December 2024

The increasing prevalence of collaborative arts engagements in recent years underscores the ongoing need to redefine ethical, caring relationships within artistic co-creations. Concurrently, the concept of Ethics of Care (EoC) has been integrated into community art projects, museum practices, and art education to foster dialogue on its definition and implementation in artistic and educational spaces. EoC is an ethic grounded in voice and relationships. It refers to promoting relational care based on contextual decision-making and attention to emotional, physical, and social needs (Gilligan, 1982; Sander-Staudt, 2018). This article presents findings from a study on the EoC among leading Social Practice artists whose work engages communities in discussion, collaboration, and social interaction. The cross-case study analysis of these creative practitioners highlighted findings that include manifestations of EoC, such as acknowledging discomfort, boundaries, and reciprocity. While these components are present in all human interactions, this article advocates for leveraging these findings as key indicators within community arts engagements. These components deepen understanding of EoC and show how to cultivate strategies for collaborative art practices. This article proposes integrating EoC in community art by embracing discomfort, recognizing explicit boundaries, and fostering relational reciprocity to build a sense of belonging within communities.
Las inundaciones del invierno 2009-2010 en la prensa, un recurso educativo para las ciencias sociales
Authors: Cuello Gijón Agustín
Published: December 2024

In the winter of 2009 to 2010 took place in Andalusia (Spain) an important episode of floods that occupied a prominent place in the media for more than three months. The article presents a study that analyzes and evaluates the educational potential of the journalistic treatment of this event, in order to offer new resources and educational options for classroom work, surpassing the simplifying models that are proposed from textbooks in education high school.
Based on a review of nearly four hundred news items, information units are identified and organized, structured into categories with desirable school content, offering a complex and multifocal view of the phenomenon of floods and their relationship with the urban system.
The media with the highest circulation in the area generated a great deal of information, especially in reference to the Guadalquivir and Guadalete rivers, the most affected, with numerous data on the territorial and social characteristics of flooded areas, river dynamics and models ideological and scientific that use different social agents to interpret these phenomena.
The enormous amount and diversity of information collected, with its filters, biases and conflicts of interests, offers educational opportunities of enormous interest to bring students to a more complex, integrated and sustainable conception of rivers, their relations with the city and the flood episodes.

“My Kidney Disease, My World as an Arena:” Unpacking the Situation of Adolescents from the Perspective of Postmodern Grounded Theory
Authors:   Universidad del Sinú, Ruidiaz Gómez Keidis Sulay , Cacante Caballero Jasmín V. ,   Universidad de Antioquia
Published: December 2024

Objective. To explore the meanings of quality of life for adolescents with chronic kidney disease (CKD).

Methods. This qualitative study was conducted using a grounded theory situational analysis approach, following the interpretive turn. Four in-depth interviews were conducted with adolescents with CKD, five with parents, and four with healthcare professionals (three nurses and one physician). The collected data were analyzed using situational maps, social world/arenas maps, and positional maps, as proposed by Adele Clarke.

Results. The characterization of these adolescents’ situations shows that they are the main actors and modify their social role when they suffer from CKD. It is the mothers that traditionally care for them, until they regain their health. The social world map shows the interactions among the worlds of individuals, their families, and the healthcare system, constituting a well-being arena which defines the quality of life for adolescents with CKD. Discursive positions constitute a key element in the discussion concerning the relational dimensions of well-being and the feelings emerging in relation to the disease.

Conclusion. For adolescents with CKD, quality of life is defined as the state of well-being emerging from the recognition of their own environment in micro-, meso‑, and macro-systems, which bring together structural (political, cultural, symbolic) elements, discursive constructions, and the integration of interactions in the social arenas, as well as the representation of the main discourses and their positions.
THE IMPRESSION OF INCLINED MAGNETIC FIELD ON MAXWELL FLUID OVER A STRETCHING CYLINDER WITH MELTING HEAT

Published: November 2024

The unique aspects of inclined magnetic field are harnessed across multiple disciplines encompassing diagnostic imaging (MRI), particle acceleration, magnetic levitation (Maglev), magnetic data storage, magnetic sensing and orientation devices. The concept of melting in the context of Maxwell fluid flow is particularly significant in the study of non-Newtonian fluid mechanics. The melting boundary condition helps to optimize the flow and cooling rates, ensuring the quality and uniformity of the final product. Therefore, the present aim is to characterize the impact of inclined magnetization along with heat source and chemical reaction in Maxwell non-Newtonian fluid via a stretching cylinder. A distinctive feature of this research is the adoption of Thompson and Troian slip and melting heat boundary constraint yielding optimized thermal transport. Similarity analysis facilitates the reduction of the governing equations, which are then addressed using bvp4c. Visualizations of physical behavior are provided graphically for key factors, accompanied by validation tables. The velocity undergoes substantial amplification for elevated melting factor. Analysis reveals a negative correlation between magnetic factor, slip factor and velocity.

De sapateiros e escritores: Graciliano Ramos e a literatura como trabalho manual
Authors: Verçosa Thayane
Published: December 2024

A querela protagonizada no final da década de 1930 por Graciliano Ramos, Mário de Andrade, Jorge Amado e Joel Silveira acerca do estilo na literatura é aqui tomada como ponto de partida para uma breve análise da perspectiva polêmica de Graciliano sobre o fazer literário, abertamente avessa aos pressupostos da cultura parnasiano-bachaleresca predominante, mas ao mesmo tempo irredutível ao programa estético do Modernismo de 22. Neste trabalho, propomo-nos, portanto, a destacar e analisar como tal postura se faz presente, seja como assunto principal, ou como pano de fundo, em quatro textos graciliânicos: “Os sapateiros da literatura” (1939), “Os tostões do sr. Mário de Andrade” (1939) – parte da mencionada querela –, “Traços a Esmo I” (1921) e “O romance de Jorge Amado” (1935).
Tradição clássica em Primeiras estórias  de J. Guimarães Rosa
Authors: Werner Christian
Published: December 2024

Investiga-se como narradores e personagens de três contos de Primeiras estórias (“O espelho”, “Pirlimpsiquice” e “Darandina”), de João Guimarães Rosa, utilizam a cultura clássica. O corpus examinado aponta para duas formas distintas: uma subserviente, quiçá rígida, e o mais das vezes explícita, geralmente indicativa de uma postura política e moral conservadora, outra, mais livre e solta e muitas vezes implícita.
O Modernismo e a Revolução de 1930: alguns aspectos
Authors: Junior Valdemar Valente
Published: December 2024

Este texto tem por objetivo evidenciar a importância da Semana de Arte Moderna como evento responsável por sucessivas tomadas de posição no âmbito de uma crítica à situação cultural, social e política do país. Por sua vez, com o advento da Revolução de Outubro de 1930, verifica-se uma alteração no modus operandi da sociedade brasileira. Isso passa a ter efeito a partir do instante em que a segunda geração modernista aproveita-se das conquistas formais do primeiro momento para evidenciar os descaminhos de nossa sociedade e denunciar nossa condição de subdesenvolvimento. A isso acrescenta-se um recorte neorrealista como tendência que acompanha a crise mundial e sua repercussão em um país de economia dependente que absorve esse duro golpe não tendo como reagir de outro modo, senão através da incorporação de sua realidade ao discurso ficcional e poético. Diante disso, o presente texto apresenta um recorte que tem por base a configuração modernista desde o seu início até a sua terceira fase.[1] Doutor em Ciência da Literatura pela UFRJ.

Decadência denunciada pelo riso: gênero, intertextualidade e crítica no Satyricon
Authors: Martins Caroline Morato
Published: December 2024

Neste artigo propomos a ideia de que a obra latina Satyricon, escrita sob o governo de Nero (54-68 d.C), apresenta evidentes alusões ao seu tempo de forma crítica e denunciatória. Porém, considerando o contexto político-social aristocrático da obra, apresentamos a ideia de que a mobilização de gêneros e tradições literárias, a intertextualidade e o riso é feita na obra com o propósito de construir dissimuladamente uma denúncia da decadência moral e artística da sociedade romana coetânea ao Satyricon. Neste sentido, analisaremos como as dificuldades de classificação desta obra em gêneros literários, sua vasta intertextualidade e seu evidente caráter cômico coadunam para uma crítica a decadência moral romana. Avaliamos brevemente, para este caso, a apresentação na obra do personagem fictício de um rico liberto, chamado Trimalquião, que se mostra indecoroso, vicioso e imoderado.
Auroras diversas de todas as épocas, de Paul Valéry
Authors: Lucas Fábio Roberto , Ribeiro Daniel Glaydson
Published: December 2024

Este texto apresentará a tradução de quatro poemas de Paul Valéry sobre a passagem da aurora, uma experiência privilegiada para se pensar a poética do escritor francês, dentro da qual o traduzir tem um papel central como ato que prolonga o inacabamento e as hesitações do poema, partilhando com o leitor combinações mais sutis entre o som e o sentido, entre a voz e o pensamento, entre o corpo, a linguagem e o mundo. Esses poemas foram publicados na seção “Pièces diverses de toute époque” das Poésies valerianas reunidas em 1942, seção que trazia a esparsa escrita em verso burilada pelo poeta após a publicação de Charmes e do Album des vers anciens, na década de 1920.

stories, surviving, and what a poem can do? in Deborah Miranda’s Bad Indians
Authors: Jackson Cj
Published: December 2024

This essay reads the poetry in Deborah Miranda's Bad Indians as a form of re-storying, a way of retelling stories and reclaiming the historical memory of those stories without abandoning their subjectivities, and without falling into the constraint of rules of determine stories must have a particular ‘structure’; must be ‘accurate and unchanged’; and must always, retellings, represent some sense of ‘truth’. This essay opens with and is primarily composed of close readings of three poems, which include: "Los Pájaros," "Lies My Ancestors Told for Me," and "Ishi at Large.” The decision to structure the essay in this manner is meant to underscore how poetry provides the historical and cultural lens for understanding California Indians history, and for recognizing how California Indian ways of being impact how we read poetry simultaneously. In doing so, this essay illustrates how Miranda's writing refuses to settle with making counter-narratives to colonial logics but is further entwined with the difficult task of bringing certain omissions, clues, lies, shards, into the light and reaffirming their relationality to one another.
Discursos del General Rafael Uribe Uribe
Authors: Uribe Uribe Rafael
Published: December 2024

El presente número de la Revista Colombiana de Filosofía “Sin Fundamento” llega a su edición n° 20, dedicado esta vez a celebrar dos acontecimientos de grata recordación para la Universidad Libre, a saber, un siglo de formación académica de manera ininterrumpida, y, de otra parte, recordar la labor legislativa que pronunció ante el Congreso el General Rafael Uribe Uribe en 1908 con motivo de los debates suscitados en materia de ordenamientoterritorial.
Los estudiosos de la geografía política de Colombia, coinciden en afirmar que el General Rafael Uribe Uribe fue el gestor de la reforma en materia de división territorial, pero fue en el gobierno de Rafael Reyes (1904-1909) que se materializó esta aspiración en 1908, al configurar el país en 34 departamentos y erigir a Bogotá como distrito especial.
Helicobacter pylori seropositivity and its associated factors in children from suburban area in Yangon
Authors: Win Phyu Phyu , Win Lei Lei , Naing Zay Yar
Published: November 2024

Background: H. pylori has infected about 50% of the global population. The infection rate in children differs across countries, being lower in high-income nations (34.7%) compared to low- and middle-income countries (50.8%). This study aimed to assess the risk factors associated with the seroprevalence of H. pylori infection among individuals aged 2 to 16 in Insein Township, Yangon Division, Myanmar.
Methods: A community-based cross-sectional study was conducted in Insein Township. A total of 193 children, aged 2 to 16 years and of both genders, were randomly selected. An in-house enzyme-linked immunosorbent assay (ELISA) was used to determine serum H. pylori IgG antibodies. Statistical analysis was performed using chi-squared tests, and mean scores between groups were compared using two-sample t-tests.
Results: Out of 193 children, (67.36%) were tested positive for H. pylori antibodies. The average age of the participants was 7.6±3.85 years. Although H. pylori positivity was highest among those with birth order 1 (71.01%) and lowest (56.52%) in those of birth order 6, it was not statistically significant. There was a higher percentage of H. pylori seropositivity (87.77%) among children with recurrent abdominal pain. The rate of H. pylori antibody positivity was higher (85.71%) among those with a family history of peptic ulcer.
Conclusions: The infection rate of H. pylori remains high among children in developing countries, highlighting the need for comprehensive prevention and treatment programs. Early diagnosis can greatly reduce complications later in adulthood and could have a significant impact on the country’s socio-economic status.
An epidemiological study on menstrual knowledge among school going adolescent girls of 9th-12th standard of northwestern Punjab: a government private school comparison
Authors: Sukriti  , Padda Preeti , Mahajan Sanjeev
Published: November 2024

Background: Although menstrual knowledge is pivotal in adolescent health education, shaping girl’s understanding of their bodies, reproductive health, and overall well-being but difference is seen in knowledge of government and private school adolescent girls. Therefore, a study was planned to compare menstrual knowledge of government and private school adolescent girls and determine its associated factors.
Methods: A cross-sectional study was conducted in 28 senior secondary schools (14 government and 14 private) of Amritsar district, Punjab from which 1120 adolescent girls studying in class 9th,10th,11th and 12th standard (10 per class per school) were randomly selected. A semi-structured questionnaire was self-administered to collect the information from the study participants and data was analysed using SPSS version 21.0 and chi-square and unpaired t-test was used to establish association.
Results: The study reveals that overall mean score for private school goers was found to be 3.6±1.32 which was significantly higher than the government school goers (2.4±1.53). Menstrual knowledge was found to be associated with age, place of residence, type of family, caste, socio-economic status, educational and occupational status of both the parents.
Conclusions: Knowledge was found to be better among private in comparison to government school adolescent girls.

Authors: Kaware Alka , Pothipogu Tejaswi , Ingle Prachi , Deshmukh Jyostna
Published: November 2024

Background: Rabies is an infectious disease with hundred percent mortality that can be prevented by taking action pre or post exposure to the agent. The individuals’ beliefs, customs and traditions play a major role in any health care practices. In this study we tried to assess the epidemiological determinants, vaccine hesitancy and adverse events following vaccination. Objectives were to study the epidemiological determinants of the individuals with animal bite and to study the vaccine hesitancy and adverse events following vaccination.
Methods: A prospective cross-sectional study was conducted among the 300 individuals who came with animal bite to the anti-rabies vaccination centre. The study participants were recruited through convenience sampling.
Results: Out of 300 participants 102 (34%) were of age group 15-35 years. Males 188 (62.7%) and females 112 (37.3%). The common animal that reported to bite was dog which was seen in 85.7% of study population. Vaccine hesitancy was observed in 16.7% (50). The 83% (249) participants took the ARV vaccination within 24 hours of the animal bite. The most common adverse events following vaccination reported is skin discoloration at the injection site by 53.3% (160).
Conclusions: The vaccine should be made available even in the rural, suburban areas. Newer vaccine with better preservatives should be made to prevent adverse events.
