The Schröeder-van Laar equation to predict the theoretical eutectic melting temperature values was applied to a set of fourteen binary mixtures (UR1 to UR14). The fourteen binary mixtures belong to a structurally diverse group of organic molecules. They are represented by the 5-membered heterocycles containing N-S and N-O rings, flexible methylene chains (RH), semi-rigid semi-fluorinated chains (RF), and hydrogen bonds (HB). A virtual screening totalizing ninety-one possible theoretical combinations was planned. The UR1 to UR14 were prepared by mixing individual components using the calculated mole fractions. The experimental (Te) and theoretical (Tt) temperatures for the eutectic melting points were determined using polarized optical microscopy (POM) and differential scanning calorimetry (DSC) techniques. Heterogeneous mixtures were formed for components with large structural diversity as seen by POM. During the melting of the mixtures, irregular behavior through the segregation of the components was recorded. The study showed that the similarities in structural diversities favor the formation of homogeneous mixtures, with Te values approaching Tt, as predicted by the Schröeder-van Laar equation and by the theory of eutectic mixtures. Liquid crystal properties were affected in homogeneous binary mixtures containing one of the individual liquid crystal components. Schröedervan Schröeder van UR (UR UR14. .

The emergence of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) stands for being the most serious epidemic (so far) of the 21st century. However, only a few computational studies have investigated the molecular mechanisms underlying the neutralization of the spike protein by antibodies of different classes. Hence, bioinformatic methods were employed to unravel the factors contributing to the remarkable neutralization capacity exhibited by specific antibodies. Initially, crystallographic structures of IgA monomeric / dimeric, IgG, and IgM antibodies binding with the receptor-binding domain region of the SARS-CoV-2 spike protein were retrieved. Subsequently, rigid molecular docking and molecular dynamic simulations were performed over 100 ns with explicit water solvation. Lastly, an energy decomposition was conducted to estimate the binding affinity using the last frames from molecular dynamics. The results revealed a higher binding affinity for both monomeric and dimeric forms of IgA antibodies against the spike protein. Additionally, a greater number of hydrogen bonds were observed during their interaction with the spike protein, as well as greater structural instability along the time and especially a more thermodynamically favorable interaction affinity. In this way, the research contributes a small piece to the complex puzzle of understanding the humoral immune response induced by the SARS-CoV-2 virus.

The in silico study aimed to suggest phytochemicals from Commiphora leptophloeos leaves essential oil as therapies against coronavirus disease (COVID-19) (or severe acute respiratory syndrome coronavirus 2, SARS-CoV-2). For that, we used molecular docking (MD), absorption, distribution, metabolism, excretion, and toxicity (ADMET) parameters, and pharmacokinetic analysis. MD showed the presence of hydrophobic and hydrogen bonds for nine compounds. β-Selinene and bicyclogermacrene showed the best interaction values with the protein Mpro (ID: 6Y2F) (-5.9) and chimeric receptor complexed with its receptor human ACE2 (ID: 6VW1) (-6.1 and -5.5) proteins, as well as low gastrointestinal and high epithelial absorptions, medium permeability for Caco-2 cells and high epithelial permeability, low oral excretion, and were inhibitors of CYP2C19 and CYP2C9 enzymes. On the other hand, both were not permeable to the blood-brain barrier and inhibitors or substrates for glycoprotein-D, and showed carcinogenic potential, but only β-selinene was considered mutagenic. Although little bioavailable, both presented aspects structurally adequate, being compounds with moderate synthesis difficulty. Therefore, more analyses are necessary to evaluate the mechanism of action and unsatisfactory parameters foreseen in bioinformatic assays. COVID19 COVID 19 (COVID-19 2 SARSCoV2.

In this work, using the PM3 semi-empirical method, the oxidation of the single-walled carbon nanotube (SWCNT) was studied by sulfuric and nitric acid for the incorporation of carbonyl (C=O), phenol (OH) and carboxylic (COOH) groups in the C=C bonds present on the surface of the nanotube. Subsequently, the crosslinking of the oxidized SWCNT (SWCNTox) and chitosan (Q) was observed through hydrogen bonds of the C=O and OH bonds with 2.34 Å, the process was endothermic and soluble in polar solvents due to the presence of OH and NH groups in the structure of SWCNTox/Q. The Monte Carlo modeling allowed to study the adsorption of pesticides in the SWCNTox/Q at different temperatures, where the QSAR (quantitative structure activity relationship) properties allowed predicting the behavior of the pesticides, that is, the degree of hydrophobicity (log P) and accessible surface area (ASA) were important parameters in the evaluation of SWCNTox/Q as an adsorbent and surface interacting with pesticides respectively. Finally, the adsorption was a physisorption process due to the electronegativity of the CO, OH, NH2, NH and C=O bonds. work PM semiempirical semi empirical method singlewalled single walled (SWCNT C=O, CO , C O (C=O) (OH COOH (COOH CC Subsequently SWCNTox (SWCNTox Q (Q 234 2 34 2.3 Å SWCNToxQ temperatures quantitative relationship is log P ASA (ASA respectively Finally NH2 (C=O 23 3 2.

ABSTRACT This paper attempts to demonstrate how the artworks in the exhibition "Madres plantas y mujeres luchadoras. Visiones desde Cantagallo", created by the Shipibo artists of the Non Shinanbo collective, constitute a testimonial record that evidences the strategies that emerged within Cantagallo, an urban indigenous community, in the context of the measures taken by the Peruvian State during the first stage of the Covid-19 pandemic. Through the "reading" and analysis of a selection of artworks and based on interviews with the artists, it will be illustrated how their work creates an effective testimony that emphasizes the empowerment of the women in the community, the significance of the bonds of solidarity within the community and the relevance of Shipibo traditional knowledge, which is open to heterogeneous elements, thus evidencing its modernity and complexity.

Abstract One of the key elements of feminist theory and practice is the questioning of the preestablished structures for relating that dictate who we should get close to and when, and the insistence on creating affective bonds that go beyond those allowed by the mandates. Coming from the field of children’s studies we invoke those elements as we intend to study the ways in which teenage girls and adult women -members of a social organization called AulaVereda- bonded with each other while participating in the feminist movement, in the city of Buenos Aires, Argentina, during the years of 2018/ 2021. Using an ethnographic approach, we identified two different ways of bonding between the age groups emerging in the daily life of the organization. A pedagogical bond, on the one hand, and what we are calling a compañeras bond, on the other. We analyze these two styles using the metaphors of occupying knowledge and occupying the street, respectively. The results of the investigation allow us to argue that the democratization of political participation comes hand in hand with an intergenerational feminism.

Resumen Uno de los ejes centrales de la teoría y práctica feminista ha sido el cuestionamiento a las normas vinculares preestablecidas y la apuesta por crear lazos afectivos más allá de los mandatos que establecen a quiénes nos debemos aproximar y cómo. Invocando estas operatorias desde el campo de la antropología de la infancia y las edades, en este trabajo nos proponemos estudiar las formas vinculares que se desplegaron entre las adultas y las niñas de la organización social AulaVereda en el marco de su participación en el movimiento feminista, en la Ciudad de Buenos Aires (Argentina) durante los años 2018-2021. Desde un abordaje etnográfico y del análisis denso de registros de campo, identificamos dos modos de relación entre grupos de edades que se yuxtaponen y conviven en la cotidianeidad de la organización: un vínculo pedagógico y un vínculo de compañeras, que analizamos a partir de la figura de ocupación del conocimiento y ocupación de la calle respectivamente. Los datos arrojados por la investigación nos permiten argumentar por la democratización etaria de la política de la mano de un feminismo intergeneracional.

Abstract: Objective: To analyze the care practices produced by nurses in primary care with families from the perspective of health promotion. Method: An exploratory descriptive study with a qualitative phenomenological approach was conducted in 15 Basic Health Units located in the municipality of Boa Vista, Roraima, Brazil. Fifteen nurses with specialized clinical practice in family health were included. The semi-structured interview design included thirteen questions that address the performance of nurses in the primary health unit and their care practices directed at families. The interviews lasted an average of thirty minutes and took place in private environments, represented by nursing offices and meeting rooms of the selected health services. Content analysis was conducted manually, guided by Laurence Bardin’s framework in three specific stages, namely: pre-analysis, data processing, and interpretation. Results: Within the scope of the care practices carried out by primary care nurses with families, there was an appreciation of bonds as a crucial element for health promotion. The humanistic aspects involved in health education improve the active participation of families in self-care and promote satisfactory health outcomes. Conclusion: Nurses recognize in the practical scope of health promotion with families the welcoming, qualified listening, comprehensiveness, humanization, dialogue and human relationships as being indispensable to the production of educational health care and obtaining favorable health outcomes in primary care.

Abstract The purpose of this text is to carry out as analysis of the decisions issued in the second instance involving family members of prisoners, focusing on the Courts of Justice of Minas Gerais, São Paulo and Rio de Janeiro. Decisions published between 1998 and 2021 were collected in the three locations, forming a database, that was scrutinized in a quantitative perspective. Based on this, it was possible to notice that the judicial processes have two main focuses: requests related to the excess term of provisional detention and requests related to difficulties in visiting prisons. In the first point, the importance of families in the persecution of the rights of the inmates is clear. The decisions of the three courts on the matter differ substantially, and the claim is only effective in many cases in Rio de Janeiro. On the second point, there is an indication of how imprisonment goes beyond the person of the prisoner to reach their loved ones. In these cases, the decisions of the three courts have contributed to the transformation of family members of prisoners, especially women, into criminals, authorizing the constant surveillance of their bodies, in addition to the denial or hardening to maintain the bonds of affection between these and their prisoners. prisoners Gerais Janeiro 199 202 locations database perspective focuses prisons point clear substantially ones women criminals bodies 19 20 1 2

Resumo A proposta deste texto é analisar as decisões proferidas em segunda instância que envolvem familiares de presos, com foco nos Tribunais de Justiça de Minas Gerais, São Paulo e Rio de Janeiro. Foram coletados acórdãos publicados entre 1998 e 2021 nas três localidades, formando uma base de dados, escrutinada posteriormente numa perspectiva quantitativa. Foi possível notar que os processos judiciais têm dois focos principais: pedidos relacionados ao excesso de prazo da prisão provisória e pedidos relacionados às dificuldades na visitação em unidades prisionais. No primeiro ponto, fica clara a importância das famílias na busca de concretização dos direitos dos custodiados. As decisões dos três tribunais sobre a questão divergem substantivamente, sendo que o pleito só se efetiva em muitos casos no Rio de Janeiro. Já sobre o segundo ponto, tem-se um indicativo de como o aprisionamento ultrapassa a pessoa do preso para atingir seus entes queridos. Nesses casos, as decisões das três corte têm contribuído para a transformação, sobretudo, de familiares de presos, em especial mulheres, em criminosas, autorizando a vigilância constante de seus corpos, e dificultado a manutenção dos vínculos de afeto entre essas e seus entes presos. presos Gerais Janeiro 199 202 localidades dados quantitativa principais prisionais ponto custodiados substantivamente temse tem queridos transformação sobretudo mulheres criminosas corpos 19 20 1 2

Abstract This work seeks to contribute to the development of pedagogical strategies for dialogue with university students, in a national context marked by increasing levels of social violence, stemming from the “war on drugs” in Mexico. By revisiting concepts such as psychosocial trauma and education in emergency contexts, it highlights the need to open curricular spaces in university classrooms to reflect on the personal and collective impact arising from exposure to violence in its various manifestations. The pedagogical proposal is rooted in critical pedagogy for peace and incorporates elements of collective narrative practices, restorative circles, and mediation. Pedagogical tools are offered to enable faculty to conduct dialogue sessions with their students in a respectful and secure educational environment, aimed at strengthening social bonds and reflecting on the spaces and actions that, in their own lives, offer hope as well as possible resources for individual and/ or collective action. Listening, narrating, and acting are the three intertwined phases of this proposal. The outlined methodologies represent an effort from the educational space to advance the reconstruction of the social fabric in societies affected by widespread phenomena of violence.

Resumen Este trabajo busca contribuir al desarrollo de estrategias pedagógicas para el diálogo con estudiantes universitarios, en un contexto nacional marcado por crecientes niveles de violencia social derivados de la “guerra contra el narcotráfico” en México. Al retomar conceptos como trauma psicosocial y educación en contextos de emergencia, destaca la necesidad de abrir espacios curriculares para reflexionar sobre el impacto personal y colectivo de la violencia. La propuesta se inscribe en la pedagogía crítica para la paz e integra prácticas narrativas, círculos restaurativos y mediación. Herramientas pedagógicas permiten al profesorado conducir sesiones de diálogo en un entorno seguro, orientadas a fortalecer vínculos sociales y explorar recursos para la acción individual y colectiva. Escuchar, narrar y actuar son las fases de esta aproximación, que representa un esfuerzo desde la educación para reconstruir el tejido social en sociedades afectadas por violencia generalizada.

Abstract This research aims to understand and describe perceptions and actions of rural inhabitants challenged by severe drought and climate change affecting Chile’s central areas. It considers the cases of Santa Julia and Valle Alegre, two rural communities within the coastal city of Quintero. This area is inhabited by family agricultural households impacted by drought conditions in the last decades and close to several polluting industries. The analysis is based on the sense-making theoretical model to explain the problems that affect people’s everyday lives and their attempts to solve them by means of information produced with their own resources, within their communities and with the support of state and private agents. Between November and December 2021, the authors carried out in-depth interviews with 13 informants from both communities. The research findings suggest that severe drought leads to discontinuities both in their productive activities and community and family ties. In their search for solutions, both communities struggle with weak social bonds when attempting to organize collective action. Furthermore, they distrust local companies’ and neighbors’ help. People thus feel insecure about the future and hope that seasonal rains eventually return. In the meantime, they try to adapt and mitigate environmental impacts with the help of some public and international institutions and the application of agricultural innovations.

Resumen En el presente artículo se describen las percepciones y acciones que realizan habitantes rurales frente a la severa sequía y al cambio climático que afectan la zona central de Chile. Para ello se escogieron Santa Julia y Valle Alegre, dos localidades de agricultura familiar en la comuna costera de Quintero, perjudicadas por una prolongada sequía en las últimas décadas y cuya ubicación está próxima a varias industrias contaminantes. Se aplica el modelo teórico de sense-making para explicar los problemas que enfrentan estas personas en sus vidas diarias y cómo intentan resolverlos buscando información mediante sus propios recursos, en sus comunidades y con el apoyo de entidades estatales y privadas. Se realizaron entrevistas en profundidad entre noviembre y diciembre de 2021 a 13 informantes de ambas localidades. Los hallazgos muestran que la sequía prolongada produce problemas tanto en sus actividades agropecuarias como en su vida comunitaria y familiar. En la búsqueda de soluciones estas personas se enfrentan a una desarticulación comunitaria que dificulta acciones colectivas, y desconfían de las ayudas que puedan brindar empresas locales y vecinos. Se constata un sentimiento de inseguridad respecto al futuro, con la esperanza puesta en el eventual regreso de las lluvias estacionales, mientras se adaptan y mitigan impactos ambientales con el apoyo de algunas instituciones públicas e internacionales y mediante la aplicación de innovaciones agrícolas.

Resumo Escritos autobiográficos com conteúdo homoerótico têm refletido constantemente as lutas entre identidades dissidentes e sistemas heteronormativos. O caso de Antes que anochezca (1992) de Reinaldo Arenas não é exceção. Portanto, a hipótese desta análise afirma que o orgulho do sujeito dissidente hipersexualizado –neste caso, um sujeito autobiográfico– aparece como uma ferramenta de desestabilização normativa diante dos sistemas sexo-gênero que promovem a masculinidade e a sexualidade heteropatriarcais. Consequentemente, o discurso de Arenas incita a uma releitura do corpo para desmontá-lo das amarras impostas pelos dispositivos de poder –especialmente aquela que corresponde à ideia do “homem novo” emanado da Revolução Cubana–. Traça também a representação de um sujeito dissidente que não adere à ideologia do Norte global, mas sim a uma visão aderente ao sistema de desejo mediterrânico, regido pela dicotomia sexual do eixo activo/passivo.

Resumen Las escrituras autobiográficas de contenido homoerótico han reflejado de manera constante las pugnas entre las identidades disidentes y los sistemas heteronormativos. El caso de Antes que anochezca (1992) de Reinaldo Arenas no es una excepción. Por ello, la hipótesis de este análisis plantea que el orgullo del sujeto disidente hipersexualizado –en este caso, un sujeto autobiográfico– aparece como una herramienta de desestabilización normativa frente los sistemas sexo-genéricos que promueven una masculinidad y sexualidad heteropatriarcales. En consecuencia, el discurso de Arenas incita a una relectura del cuerpo para desmantelarlo de las ataduras impuestas por los dispositivos del poder –en especial el que corresponde con la idea del “hombre nuevo” emanado de la Revolución cubana. Además, traza la representación de un sujeto disidente que no se ciñe a la ideología del Norte global, sino a una visión adherida al sistema del deseo mediterráneo, regida por la dicotomía sexual del eje activo/pasivo.

Abstract Autobiographical writings with homoerotic content have constantly reflected the struggles between dissident identities and heteronormative systems. The case of Antes que anochezca (1992) by Reinaldo Arenas is no exception. Therefore, the hypothesis of this analysis states that the pride of the hypersexualized dissident subject –in this case, an autobiographical subject– appears as a tool of normative destabilization in the face of sex-gender systems that promote heteropatriarchal masculinity and sexuality. Consequently, Arenas' speech incites a rereading of the body to dismantle it from the bonds imposed by the devices of power –especially that which corresponds to the idea of the “hombre nuevo” emanating from the Cuban Revolution–. It also traces the representation of a dissident subject that does not adhere to the ideology of the global North, but rather to a vision adhered to the system of Mediterranean desire, governed by the sexual dichotomy of the active/passive axis.

Abstract: The purpose of this article is to critically and comprehensively approach Halbwachs' concept of Collective Memory, with the aim of recognising: i) the current relevance of this concept concerning contemporary social issues, where dominant and subaltern experiences and memories are combined within complex processes of individuation, transgenerational transmission and normative constitution of societies, ii) to compare the treatment of the concept of collective memory from the theorisations present in Halbwachs, Freud, and Canguilhem, to identify possible lines of discussion between these perspectives. For this purpose, primary sources of the main authors of the study are established as main discussion coordinates, which are complemented and discussed with contemporary appropriations of these works.

Resumen: El presente artículo tiene como propósito abordar de modo crítico y comprensivo el concepto de Memoria Colectiva de Halbwachs, con el objeto de reconocer: i) la pertinencia actual de este concepto respecto de problemáticas sociales contemporáneas, en donde se conjugan vivencias y memorias dominantes y subalternas dentro de procesos complejos de individuación, transmisión transgeneracional y constitución normativa de las sociedades, ii) cotejar el tratamiento del concepto de memoria colectiva desde las teorizaciones presentes en Halbwachs, Freud y Canguilhem, a fin de identificar posibles líneas de discusión entre estas perspectivas. Para dicho efecto, se establecen como principales coordenadas de discusión fuentes primarias de los autores principales del estudio, las que se complementan y discuten con las apropiaciones contemporáneas de estas obras.

Abstract The article proposes to address linking as a constitutive dimension of teaching and training situations. Human bonds innervate relationships of different kinds: communicational, emotional, as well as related to the exercise of power and domination. We will discuss three theoretical models from which it will be possible to interpret and understand the connection around teaching and training: the communication link; the power bond; the emotional bond. In all cases, it will be possible to notice the paradoxical meaning that linking takes on in relationships within the classroom. Paradox that, far from being understood as an obstacle or difficulty that presents itself to us in understanding reality, will be proposed as a reading key to access the complexity of humanity.

Resumen El artículo propone abordar lo vincular como dimensión constitutiva de las situaciones de enseñanza y de formación. Los vínculos humanos inervan relaciones de distinta índole: comunicacionales, emocionales, así como relativas al ejercicio del poder y la dominación. Pondremos en discusión tres modelos teóricos desde los cuales será posible interpretar y comprender lo vincular en torno a la enseñanza y a la formación: el vínculo comunicacional; el vínculo de poder; el vínculo emocional. En todos los casos, será posible advertir el sentido paradojal que adopta lo vincular en las relaciones dentro del aula. Paradoja que, lejos de entenderse como un obstáculo o una dificultad que se nos presenta frente a la comprensión de la realidad, se propondrá como una clave de lectura para acceder a la complejidad propia de lo humano.

Resumen En este artículo se aproximan algunas elaboraciones al proceso en desarrollo histórico del escenario monetario y bancario de la Provincia de Antioquia a finales del siglo XIX. Se hace tránsito por los lugares de la escasez monetaria, la emisión de moneda y las complicadas redes de capitalistas individuales, que marcarían la senda de la política monetaria y bancaria. En esta exposición, en sumo grado abstracta, la comprensión de la moneda y la banca en el caso que se convoca, más allá del carácter funcional, ayuda a detenerse en las tendencias como constitutivos de los vínculos sociales. Esto remite inmediatamente a la relación entre la emisión de billetes privados y el billete fiscal. Esto no surge súbitamente, sino que corresponde a un proceso de transformación histórica de la producción social.

Abstract This article approaches some elaborations on the historical development process of the monetary and banking scenario of the Province of Antioquia at the end of the 19th century. It goes through the places of monetary scarcity, currency issuance, and the complicated networks of individual capitalists, which would mark the path of monetary and banking policy. In this highly abstract exposition, understanding currency and banking in the case in question, beyond its functional character, helps to focus on tendencies as constitutive of social bonds. This immediately refers to the relationship between the issuance of private banknotes and the fiscal banknote. This does not arise suddenly but corresponds to a process of historical transformation of social production. JEL: N26, N20, E51.
