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. .

RESUMO: O Rio Grande do Sul possui uma grande diversidade de espécies de répteis distribuídos por todo o Estado. Devido às ações antrópicas, como a fragmentação de habitats, estes animais vêm sendo observados com frequência no meio urbano e periurbano. Isso facilita a disseminação de patógenos entre animais e seres humanos, sendo um risco a saúde única, visto que muitas doenças são consideradas zoonoses. A leptospirose está entre as zoonoses mais comuns do mundo e é causada pelas espécies patogênicas da bactéria do gênero Leptospira. Ainda não se sabe o papel dos répteis no ciclo da doença, porém, estudos sorológicos demonstraram positividade para anticorpos contra Leptospira spp. em cágados e serpentes, o que pode indicar que estes animais atuam na manutenção do patógeno no ambiente. O objetivo deste estudo foi observar a presença de anticorpos anti-Leptospira em répteis oriundos de resgate e levados ao Núcleo de Reabilitação da Fauna Silvestre e Centro de Triagem de Animais Silvestres da Universidade Federal de Pelotas (NURFS-CETAS/UFPEL). As amostras foram coletadas de 55 animais (39 Trachemys dorbigni; 3 Philodryas patagoniensis; 3 Caiman latirostris; 3 Salvator merianae; 2 Acanthochelys spixii; 2 Phrynops hilarii; 2 Hydromedusa tectifera; 1 Philodryas aestiva), durante o período de agosto de 2022 a dezembro de 2023, e testadas para 12 sorovares de referência. Dois animais demonstraram positividade, um deles para o sorovar patogênico Pyrogenes e outro para o sorovar patogênico Canicola. Este resultado demonstra a importância de outras espécies, além dos mamíferos, como potenciais reservatórios e responsáveis pela manutenção da leptospirose no ambiente.

ABSTRACT: The state of Rio Grande do Sul has a great diversity of reptile species distributed throughout its territory. Due to human actions, such as habitat fragmentation, these animals have been frequently observed in urban and peri-urban environments. This facilitates the spread of pathogens between animals and humans, posing a unique health risk, as many diseases are considered zoonoses. Leptospirosis is among the most common zoonoses in the world and is caused by pathogenic species of bacteria of the genus Leptospira. The role of reptiles in the cycle of this disease is yet unknown. However, serological studies have demonstrated positivity for antibodies against Leptospira spp. in tortoises and snakes, which may indicate that these animals act in maintaining the pathogen in the environment. This observed the presence of anti-Leptospira antibodies in rescued reptiles taken to the Center for Rehabilitation of Wild Fauna and Screening Center for Wild Animals at the Universidade Federal de Pelotas (NURFS-CETAS/UFPEL). Samples were collected from 55 animals (39 Trachemys dorbigni; 3 Philodryas patagoniensis; 3 Caiman latirostris; 3 Salvator merianae; 2 Acanthochelys spixii; 2 Phrynops hilarii; 2 Hydromedusa tectifera; 1 Philodryas aestiva) from August 2022 to December 2023 and tested for 12 reference serovars. Two animals demonstrated positivity, one for the pathogenic serovar Pyrogenes and the other for the pathogenic serovar Canicola. This result reflected the importance of different species besides mammals as potential reservoirs and responsible for maintaining leptospirosis in the environment.

Computational predictive approaches present themselves as an attractive alternative in the search for new compounds that may present toxic or growth regulatory activity in Aedes aegypti. Aspergillus species is a producer of secondary metabolites with diverse biological activities. In this study, it was possible to evaluate the pharmacokinetic and toxicological properties in silico, as well as the prediction of the insecticidal biological activities of the juvenile hormone of natural substances produced by the genus Aspergillus. Initially, 187 molecules were cataloged from various species of Aspergillus spp., and only seven molecules of indole alkaloids were found to exhibit a toxic dose 50% (TD50) after conducting toxicity predictions. The molecular dynamic simulation trajectories were utilized to study parameters such as root mean square deviation, root mean square fluctuation, radius of gyration and intermolecular hydrogen bond to understand the behavior and stability of proposed compounds in the binding pocket of the target protein. The N-β-acetyltryptamine molecule showed a binding affinity value of –8.100 ± 0.200 kcal mol-1, which classifies the compound as a potential insecticidal agent against the Aedes aegypti vector. silico Initially 18 spp spp. 50 TD50 TD (TD50 predictions deviation fluctuation protein Nβacetyltryptamine N β acetyltryptamine 8100 8 100 –8.10 0200 0 200 0.20 mol1, mol1 mol 1, 1 mol-1 vector 5 TD5 (TD5 810 10 –8.1 020 20 0.2 mol- (TD 81 –8. 02 2 0. –8 –

ABSTRACT: With advancements in coffee cultivation, several traits may be considered in selection of plants, which must exhibit a set of favorable characteristics. The outturn index, defined as the relationship between the mass of mature fruit and processed beans, emerges as a key factor influencing productivity. This study characterized the outturn over two harvests of 57 clones marketed in the public domain and 10 registered cultivars. The analysis considers the effects of genotypes, measurements, and genetic progress achieved through plant selection. According to the maturation cycle of each clone, washed samples of cherry coffee were collected considering a completely randomized factorial design for characterization of the effects of genotypes, years, and the genotype × years (GY) interaction. The drying, peeling, and the outturn index were individually assessed. Despite the significant effects of the GY interaction, genotypes demonstrated minimal alterations in their ranking across measurements. Clones with higher outturn, including LB30, BRS1216, LB12, N7, LB10, LB20, BRS3220, and AS5, exhibited an average outturn of 25.51%, reflecting a gain of 12.17%. Conversely, clones with lower outturn, such as BG180, GJ30, GJ20, AS7, AS10, P42, N1, and P60, had an average of 19.15%, indicating a reduction of 14.02% compared to the general mean. Analyzing the distribution of the outturn values, 19.4%, 62.7%, and 17.9% of genotypes were classified as high, medium, and low outturn, respectively, providing valuable insights for optimal cultivation strategies.

RESUMO: Com o avanço da cafeicultura, múltiplas características devem ser consideradas na seleção de plantas, que devem apresentar um conjunto de atributos favoráveis. O rendimento, definido como a relação de massas entre os frutos maduros e os grãos processados, é um importante componente da produtividade. Este estudo tem como objetivo caracterizar o rendimento ao longo de duas colheitas de 57 clones comercializados em domínio público e 10 cultivares registradas. A análise considera efeitos de genótipos, medições e estimativas de ganhos com a seleção. De acordo com o ciclo de maturação de cada clone, amostras de café cereja foram colhidas considerando um delineamento fatorial inteiramente ao acaso para a caracterização dos efeitos de genótipos, anos e interação genótipo × anos (GA). A secagem, o descascamento e o rendimento foram avaliados individualmente. Apesar dos efeitos significativos da interação GA, os genótipos apresentaram pequenas mudanças no ordenamento de uma medição para a outra. Clones com maior rendimento, entre eles, LB30, BRS1216, LB12, N7, LB10, LB20, BRS3220 e AS5 apresentaram rendimento médio de 25,51% associado a estimativas de ganho de 12,17%. Por outro lado, clones de menor rendimento, como BG180, GJ30, GJ20, AS7, AS10, P42, N1 e P60 tiveram uma média de 19,15% associada a uma redução de 14,02%. A partir da distribuição dos valores, 19,4, 62,7 e 17,9% dos genótipos apresentaram rendimento classificados como alto, médio e baixo, subsidiando o melhor cultivo dos genótipos avaliados.

In this study, we aimed to investigate the anticancer activity of the extract, fractions, and isolated compounds of the flowers of Fridericia platyphylla, and to characterize the bioactive compounds. The chemical diversity of the extracts and fractions was investigated using liquid chromatography coupled with high resolution mass spectrometry (LC-HRMS). We were able to annotate 26 compounds from the classes of flavones, flavonols, flavanones, isoflavones, and cinnamic acid and its derivatives. The dichloromethane fraction showed greater cytotoxicity at a concentration of 100 µg mL−1. In addition, the inhibitory concentrations of the dichloromethane fraction were 22.14 and 30.9 µg mL−1 for MCF-7 and MDA-MB-231 cell lines, respectively, and were capable of inhibiting tumor cell migration. Brachydins A and C were isolated from the dichloromethane fraction and showed the greatest cytotoxicity. The results obtained from this study show the potential biological effect of F. platyphylla flowers as a possible antitumor pharmacological agent. extract LCHRMS. LCHRMS LC HRMS .

ABSTRACT Ornamental pepper plants have genetic variability, which can be accessed through morphological and molecular traits. Genotype selection to form the base population for breeding can be performed through the joint analysis of several types of data, providing greater selection accuracy. From this perspective, this study aimed to evaluate the diversity among pepper accessions based on analysis of phenotypic traits and molecular markers and to select the best ones to use as parents in breeding programs. The study was carried out at the Centro de Ciências Agrárias of the Universidade Federal da Paraíba, Paraíba, Brazil. Sixteen ornamental pepper genotypes were used and characterized for eight quantitative traits, nine qualitative traits, and 18 pairs of microsatellite primers. Simultaneous variable analyses were performed using Tocher’s clustering method, Ward’s clustering algorithm, and the dissimilarity matrix. The clustering methods were efficient in separating the genotypes, identifying genetic variability, and accuracy in the selection through the joint analysis of quantitative, qualitative, and molecular data. Different groups were formed among the genotypes by Tocher’s method (six groups) and Ward’s method (three groups). There is genetic variability among ornamental pepper genotypes considering the joint analysis of quantitative, qualitative, and molecular data. Qualitative traits are important in the identification of genetic divergence among ornamental pepper accessions. The UFPB genotypes 46, 134, 137, 443 and 449, the mini pepper Akamu, and the cultivar Calypso are indicated for selection and can be used to carry out crosses and continue the breeding program. data perspective programs Paraíba Brazil 1 primers Tochers Tocher s Wards Ward algorithm matrix six three groups. . 46 134 137 44 449 Akamu program 4 13

RESUMO: A estrutura do sistema radicular do cafeeiro Conilon tem sido aprimorada ao longo dos anos por meio de propagação e estudos genéticos e agronômicos em resposta às demandas por melhorias no desenvolvimento vegetal, na produção e na sobrevivência da espécie. Entende-se que a pesquisa científica desempenha um papel importante na geração de tecnologias e também na segurança das aplicações. Porém, há necessidade de refinar o código gerado para descobrir descobertas e tendências sobre o assunto. Nesse sentido, o presente estudo tem como objetivo realizar uma revisão bibliométrica e análise na base de dados Web of Science (WOS) sobre as principais contribuições de estudos, pesquisadores, organizações e países relevantes nas pesquisas acadêmicas sobre o enraizamento de Coffea canephora.

ABSTRACT: The structure of the root system of the conilon coffee tree has improved over the years through propagation, genetic, and agronomic studies in response to demands for improvements in plant development, production, and survival of the species. Scientific research plays an important role in generating technologies and the security of applications. However, there is a need to refine the content generated to analyze discoveries and trends on the subject. Therefore, the present study conduct a bibliometric review and analysis on the main contributions of relevant studies, researchers, organizations, and countries in academic research on the rooting of Coffea canephora in the Web of Science (WOS) database. Data from the WOS database published between 1982 and 2021 and systematized in the VOSviewer software showed a set of 92 articles, the majority of which originated in Brazil and France, with the main groups being the Brazilian Agricultural Research Corporation, the Federal University of Viçosa, and CIRAD. The study was divided into five areas: genetic diversity, asexual propagation, nematology, tolerance to water stress, and micropropagation. However, in the context of climate changes and its impact on the production and longevity of Brazilian coffee farming, research focused on the root system has increased significantly, integrating it into lines that explore and integrate topics such as climate risk, water management, drought tolerance, and drip irrigation, including reflections on the performance of coffee agronomy.

RESUMO Introdução/enquadramento/objetivos A Esclerose Múltipla tem uma prevalência razoável e o diagnóstico faz-se geralmente em idade ativa, numa fase ainda exigente a nível profissional, altura essa onde geralmente também existem particularidades pessoais/familiares que necessitam de alguma dedicação. Para além disso, dada a incidência, diversidade e gravidade dos sintomas apresentados, com frequência surgem limitações que podem condicionar seriamente a capacidade de trabalho ou até levar ao desemprego. Será então desejável que os elementos a exercer em equipas de Saúde e Segurança Ocupacionais tenham alguns conhecimentos sobre o tema, de forma a melhor orientar o seu desempenho, salvaguardando os interesses de todos os envolvidos. Metodologia Trata-se de uma Revisão Bibliográfica, iniciada através de uma pesquisa realizada em abril de 2023, nas bases de dados “CINALH plus with full text, Medline with full text, Database of Abstracts of Reviews of Effects, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, Cochrane Methodology Register, Nursing and Allied Health Collection: comprehensive, MedicLatina e RCAAP”. Conteúdo É uma doença desmielinizante e auto-imune do Sistema Nervoso Central; carateriza-se por episódios recorrentes e intermitentes de inflamação, com destruição de mielina axonal, geralmente progressiva. Na maioria dos casos existe um ciclo de relapsos e remissões e sintomas de intensidade oscilante; a evolução é imprevisível. Causa sintomas autonómicos, visuais, motores e sensoriais; o que dificulta a vida quotidiana independente e o trabalho, tornando-se por vezes debilitante. É incurável e neurodegenerativa. A gravidade varia com as áreas neurológicas mais atingidas. À medida que a mielina se detiora, ela é substituída por cicatrizes de tecido anormal, com diferente consistência (rigidez, placas), o que perturba ainda mais a condução. Lesões nos lóbulos frontal e parietal geralmente resultam em alterações cognitivas e emocionais; na espinal medula, mais facilmente surgem problemas nos membros inferiores. Alterações no nervo ótico e lobo occipital podem originar alterações visuais. Trata-se da doença neurológica que mais limitações causa na população ativa jovem adulta. Dada a idade razoavelmente jovem do início de sintomas, irá ocorrer diminuição da qualidade de vida, mais significativa que noutras doenças crónicas. Discussão e Conclusões Ainda que a bibliografia não seja escassa, a enfase da grande maioria dos artigos não é dada à Saúde ou Segurança Ocupacionais. Seria relevante que algumas equipas a exercer em empresas grandes e com alguma incidência, avaliassem com detalhe os casos, descrevendo os principais problemas detetados, medidas propostas e avaliação posterior das mesmas, de forma a publicar não só o caminho, mas também as conclusões obtidas, para maior divulgação do assunto.

ABSTRACT Introduction/framework/objectives Multiple Sclerosis has a reasonable prevalence and the diagnosis is generally made at working age, at a stage that is still demanding on a professional level, a time when there are also generally personal/family particularities that require some dedication. Furthermore, given the incidence, diversity and severity of the symptoms presented, limitations often arise that can seriously affect the ability to work or even lead to unemployment. It is then desirable that the members working in Occupational Health and Safety teams have some knowledge on the subject, in order to better guide their performance, safeguarding the interests of everyone involved. Methodology This is a Bibliographic Review, initiated through a search carried out in April 2023, in the databases “CINALH plus with full text, Medline with full text, Database of Abstracts of Reviews of Effects, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, Cochrane Methodology Register, Nursing and Allied Health Collection: comprehensive, MedicLatina and RCAAP”. Content It is a demyelinating and autoimmune disease of the Central Nervous System; it is characterized by recurrent and intermittent episodes of inflammation, with generally progressive destruction of axonal myelin. In most cases there is a cycle of relapses and remissions and symptoms of varying intensity; the evolution is unpredictable. Causes autonomic, visual, motor and sensory symptoms; which makes independent daily living and the ability to work difficult; sometimes becoming debilitating. It is incurable and neurodegenerative. The severity varies depending on the neurological areas most affected. The function of myelin is to facilitate conduction at the level of axons; with changes in this, the electrical impulses that coordinate mental and physical functions become less effective. As myelin deteriorates, it is replaced by scars of abnormal tissue, with different consistency (stiffness, plaques), which further disrupts conduction. Injuries to the frontal and parietal lobes often result in cognitive and emotional changes; in the spinal cord, problems arise more easily in the lower limbs. Changes in the optic nerve and occipital lobe can cause visual problems. This is the neurological desease that causes most limitations in the young adult active population. Given the reasonably young age at which symptoms begin, there will be a decrease in quality of life, more significant than in other chronic diseases. Discussion and Conclusions Although the bibliography is not scarce, the emphasis in the vast majority of articles is not on Occupational Health or Safety. It would be relevant for some teams working in large companies with some prevalence, to evaluate the cases in detail, describing the main problems detected, proposed measures and their subsequent evaluation, in order to publish not only the path, but also the conclusions obtained, for greater dissemination of the subject.

ABSTRACT Traditional agroecosystems (TA) are considered more resilient to climatic extremes due to higher crop diversity and agroecological approach. The TA of Tének were studied to evaluate their drought tolerance. Open-ended questionnaire surveys, field visits, and botanical collections, with the participation of local farmers, were considered. Cultivated plant diversity was analyzed using the Shannon-Wiener diversity index (H’), and the Morisita-Horn index (CMH) in ten different agroecosystems in April and August. Remote sensing methods included the triangular greenness index (TGI). Additionally, normalized difference vegetation index (NDVI) and standardized precipitation index (SPI) were determined, covering the period from 2013 to 2022. The cultivated plant richness (P > 0.5382) and their abundance (P > 0.3622) did not change from April to August considering the total analyzed parcels. However, differences between types of agroecosystems were observed because higher diversity corresponded to managed jungle (teʼlom) (Hʼ = 1.5-1.7), and some parcels cultivated with maize (milpa) (Hʼ = 1.02-1.54). Nevertheless, in August, lower similarity was observed in milpa (CMH = 0.23-0.87) due to the absence of maize (Zea mays L.) and other herbaceous annual crops. Landscape interconnection can be affirmed with TGI correlations obtained by comparison of different TA. The negative SPI values were associated with a decrease of NDVI, but Tének polyculture agroecosystems maintained higher NDVI values compared to rainfed monocropping during the analyzed period. Tének polyculture agroecosystems exhibited higher drought tolerance, although maize and other herbaceous plants are susceptible to disappearing during prolonged drought events, thereby increasing food insecurity.

Resumen: En el escenario contemporáneo, el poder crítico de las ciencias sociales se ha visto cuestionado. Por un lado, reconocemos la democracia como una arena agonística (Mouffe), en la que el consenso significa la muerte. Por otro, la fragmentación de las demandas debilita los logros democráticos, vaciando la idea de emancipación. Destacamos los feminismos y las formas en que abordan el contenido emancipatorio de las políticas identitarias. Señalamos el peligro de confundir la afirmación de las identidades con el término identitarismo, en connivencia con esencialismos que pueden conducir al extremismo. Sin embargo, nos esforzamos por demostrar que la crítica, en sentido ecuménico, no produce un antagonismo entre emancipación e identidad, exponiendo preliminarmente la diversidad de argumentos desde la teoría crítica feminista, el feminismo post-estructuralista hasta los feminismos negros, que nunca han sido tan elocuentes. Finalmente, proponemos la escucha como condición básica para quien quiera llamarse parte del proyecto de las teóricas críticas.

Abstract: In the contemporary scenario, the critical power of the social sciences has come under challenge. On the one hand, democracy is acknowledged as an agonistic arena (Mouffe) where consensus might mean its demise. On the other hand, the fragmentation of demands weakens democratic achievements, undermining the concept of emancipation. To understand this, we focus on feminisms and their approaches to the emancipatory content of identity politics. We discuss the dangers of conflating the affirmation of identities with the term “identitarianism,” which, in complicity with essentialisms, poses a risk of extremisms. In other perspective, we seek to demonstrate how criticism, in an ecumenical sense, does not generate an antagonism between emancipation and identity, presenting the diversity of arguments from feminist critical theory to post-structuralist feminism and black feminisms that have never been so eloquent. Finally, we propose “listening” as a foundational condition for those who intend to self-identify as part of the project of critical theories.

Resumo: No cenário contemporâneo, a potência crítica das ciências sociais tem sido desafiada. De um lado, reconhecemos a democracia como arena agonística (Mouffe), em que o consenso significa sua morte. De outro, a fragmentação das demandas fragiliza as conquistas democráticas, esvaziando a ideia de emancipação. Destacamos os feminismos e os modos como lidam com o conteúdo emancipatório das políticas identitárias. Atentamos para o perigo de se confundir a afirmação das identidades com o termo identitarismos em conivência com essencialismos que podem derivar em extremismos. Buscamos, porém, demonstrar que a crítica, em sentido ecumênico, não produz um antagonismo entre emancipação e identidade, expondo em caráter preliminar a diversidade dos argumentos desde a Teoria Crítica feminista, passando pelo feminismo pós-estruturalista, até os feminismos negros que nunca foram tão eloquentes. Propomos, por fim, a escuta como condição basilar para quem pretende se autodenominar parte do projeto das teóricas críticas.

Resumen En este artículo se sustenta que el servicio de educación indígena de Baja California, el cual opera desde hace más de 40 años, posee características que lo distinguen de otros similares que se desarrollan en diversos estados de la república mexicana. En este caso, su crecimiento está articulado a los procesos de migración interna, cuya diversidad cultural y lingüística está presente en las aulas. Para lograr una descripción pormenorizada de sus principales rasgos, se realizó un análisis estadístico con información obtenida de las bases de datos de la Coordinación Estatal de Educación Indígena, de la prueba Planea, de la estadística educativa del Formato 911, así como de entrevistas aplicadas a informantes clave. Los resultados permiten identificar el tipo de organización de los centros escolares, los perfiles académico y lingüístico del profesorado y del alumnado, así como sus especificidades y retos para continuar brindando el servicio.

Abstract In this article it is founded that the indigenous education service in Baja California, which has been operating for more than forty years, has acquired characteristics that distinguish it from other similar services that operate in different states of the Mexican Republic. In this case, its growth is linked to internal migration processes. Hence, the cultural and linguistic diversity in the classrooms. In order to achieve a detailed description of their characteristics, a statistical analysis was carried out with information from the databases of the Coordinación Estatal de Educación Indígena, the PLANEA test, and the educational statistics of the Formato 911, as well as interviews with key informants. The results allow to identify the type of organization of the schools and the academic and linguistic profiles of teachers and students, as well as their specificities and challenges to continue providing the service.

RESUMEN En Paraguay en el periodo 2002 al 2022, los cambios en las familias se dieron por influencia de procesos de modernización y modernidad que se estudian teniendo como eje explicativo principal a los avances en la condición de la mujer, para los cuales también se analizan sus autonomías (económica, política y física). Se estudian: diversidad de tipos de los hogares, cre- cimiento de las uniones consensuales y crecimiento y bases de la jefatura femenina de hogar. Los datos del censo de 2002 y las encuestas de hogares del 2012 y 2022 del INE se compararon, porcentualmente. La orientación general es hacia la modernidad, pero no en las tres áreas; paralelamente se observa un aceleramiento de los procesos en el último decenio. Entre los tipos de hogares se halla el crecimiento del monoparental y el decrecimiento del extendido. La explosión de las uniones consensuales en la última década no necesariamente es modernidad; es un fenómeno tardío en la región. En 2022 ya se tiene un equilibrio entre uniones formales e informales. La creciente jefatura femenina de hogar es un indicador de modernidad; son casi 4 de cada 10 hogares familiares en 2022 habiendo crecido casi 2,5 veces en el lapso estudiado; inclusive en hogares nucleares completos. Para alcanzar esta condición política, las mujeres debieron integrarse al mercado de trabajo y lo hacen según su estado civil; por ejemplo, sepa- radas y divorciadas se ubican en el más alto nivel en ambos indicadores. Corresponde mayor estudio a las familias e incorporar a la agenda pública la diversidad familiar y sus cambios en curso para políticas públicas más precisas.

ABSTRACT In Paraguay (2002-2022), families undergone changes due to modernization and modernity processes that are studied based upon woman´s progress as main explanatory axis, and taking also in account her economic, political, and physical autonomies. Diversity of types of households, consensual unions growth, and feminine household headship, growth and its base are studied. INE´s census 2002 and 2012 and 2022 surveys data are compared (%). A general trend towards modernity is underway but it is not uniform within these three areas, and an acceleration pace during the last ten years is a parallel process. Within types of households, the one-parent and children household increase and the extended household decrease are noted. Consensual unions exploded during the last decade does not necessarily mean modernity; it is a late process in the region. By 2022, an equilibrium has arrived between formal and informal (consensual) unions. A growing feminine headship is a modernity sign, it has reached almost 4 out of every 10 households in 2022 and it has grown almost 2,5 times within 20 years, included two-parents and children family, ”the” model. For reaching this political level, wo- men should be within the labor market, and they do according to their civil-conjugal state; for instance, separated and divorced women are on the peak at both variables. Within the public agenda, more studies on families are required as well as to include families´ diversity and their ongoing changes for more precise public policies.

Abstract Introduction. Chickpea has been considered a restricted host species for nodulation, although recent studies describe a greater bacterial diversity associated with the crop to increase the knowledge about this symbiosis in orden to obtain efficient isolates in its contribution. Objective. To characterize and identify an isolate obtained from chickpea plant nodules and evaluate its effectiveness under field conditions. Materials and methods. The research was conducted in the laboratories of two centers: the Institute of Fundamental Research in Tropical Agriculture “Alejandro de Humboldt,” Cuba, and the National Center for Genetic Resources, Mexico, as well as under field conditions in two campaigns during the years 2018 and 2020 to demonstrate its effectiveness in crop interaction in the first center. The isolate R3 was taxonomically identified through the sequencing of four genes. For laboratory experiments, a completely randomized design was used, while plant trials were conducted under a randomized block design. The results were subjected to analysis of variance, and means were compared using the Tukey test (p<0.05). Results. The isolate R3 showed variability in terms of its morpho-physiological and biochemical characteristics. Furthermore, it exhibited significant differences compared to the other treatments in the growth and yield indicators evaluated in chickpea. Conclusions. Rhizobium pusense associated with chickpea nodules was identified for the first time in Cuba. The strain demonstrates growth at pH levels between 5.5 and 9.0 and temperature ranges from 29 °C to 38 °C, indicating its tolerance to these factors. Its inoculation in chickpea stimulates nodule formation and increased yield-related variables.

Resumen Introducción. El garbanzo se consideró durante muchos años una especie de hospedero restringido para la nodulación, aunque estudios recientes describen una mayor diversidad bacteriana asociada al cultivo que permita incrementar los conocimientos acerca de esta simbiosis para obtener aislados eficientes en su contribución. Objetivo. Caracterizar e identificar un aislado obtenido a partir de nódulos de plantas de garbanzo y evaluar su efectividad en condiciones de campo. Materiales y métodos. La investigación se desarrolló en los laboratorios de dos centros: Instituto de Investigaciones Fundamentales en Agricultura Tropical “Alejandro de Humboldt”, Cuba y en el Centro Nacional de Recursos Genéticos, México, así como en condiciones campo en dos campañas durante los años 2018 y 2020, para demostrar su efectividad en la interacción del cultivo en el primer centro. El aislado R3 se identificó a nivel taxonómico mediante la secuenciación de cuatro genes. Para los experimentos en condiciones de laboratorio se utilizó un diseño completamente aleatorizado, mientras que los ensayos con plantas se realizaron bajo un diseño de bloques al azar. Los resultados fueron sometidos a un análisis de varianza y las medias se compararon según el test de Tukey (p < 0,05). Resultados. El aislado R3 mostró variabilidad en cuanto a sus características morfo-fisiológico y bioquímicas. Además, tuvo respuesta con diferencias significativas con respecto al resto de los tratamientos en los indicadores de crecimiento y rendimiento evaluados en el garbanzo. Conclusión. Se identificó por primera vez en Cuba Rhizobium pusense asociado a nódulos de garbanzo. La cepa mostró un crecimiento positivo a pH entre 5,5 y 9,0 y rangos de temperatura desde 29 ºC hasta 38 ºC, lo que evidencia su tolerancia a estos factores. Su inoculación en garbanzo estimuló la formación de nódulos e incrementó variables del rendimiento.

Abstract Introduction. Evaluating onion cultivars (Allium cepa L.) in different environments to understand their adaptation is important due to the crop’s relevance in food supply across various countries, the reduction in its genetic diversity, the loss of beneficial traits, and resistance to diseases and pests. Objective. To assess the agronomic performance of onion cultivars under different environments to identify the best ones in terms of adaptation, yield, and interaction. Materials and methods. From November 2017 to August 2018, at the La Selva Research Center of the Corporación Colombiana de Investigación Agropecuaria (AGROSAVIA), Rionegro, Antioquia, Colombia, twenty-one onion cultivars plus two controls were evaluated: Peruana of the Aggregatum group and Yellow Granex of the Cepa, under open-field and protected conditions with plastic roofing, using multilocation trials in a randomized complete block design and four replications. Evaluations were consucted on categories such as bulb weight, number, length, and diameter, along with the interaction of cultivars and environments. Results. In othe open field, due to lower temperatures compared to those recorded under protected conditions resulted in higher yields of weight and number of bulbs. Under protected environments, Aggregatum group cultivars behaved as if they were from the Cepa group, producing fewer large-size bulbs. The adaptation of cultivars varied by environment: in the open field, L55 and L63 cultivars exhibited the best yields, while under protected conditions, RPT20 and RPT11 showed the best adaptation. Conclusion. Environments significantly influenced the behavior of Aggregatum group cultivars, with higher production of extra-large bulbs. Temperature contrasts in protected enviroments with plastic roofing affected cultivars yields, while open-field conditions were more favorable.

Resumen Introducción. La evaluación de cultivares de cebolla (Allium cepa L.) en diferentes ambientes para conocer su adaptación es importante debido a la relevancia del cultivo en la alimentación en diferentes países, la reducción de su diversidad genética, la perdida de sus rasgos benéficos y la resistencia a enfermedades y plagas. Objetivo. Evaluar el comportamiento agronómico de cultivares de cebolla bajo diferentes ambientes, para identificar los mejores en adaptación, rendimiento e interacción. Materiales y métodos. De noviembre 2017 a agosto de 2018, en el Centro de Investigación La Selva de la Corporación Colombiana de Investigación Agropecuaria (AGROSAVIA), Rionegro, Antioquia, Colombia, se evaluaron veintún cultivares más dos testigos de cebolla: Peruana del grupo Aggregatum y Yellow Granex del Cepa, bajo condiciones de campo abierto y protegido con techo plástico, con ensayos multilocacionales en un diseño de bloques completos al azar y cuatro repeticiones. Se evaluó por categorías: peso, número, longitud y diámetro de los bulbos; junto con la interacción de los cultivares y los ambientes. Resultados. En campo abierto, por presentar temperaturas menores a las registradas en las condiciones protegidas, se obtuvieron los mayores rendimientos de peso y número de bulbos. En ambientes protegidos, los cultivares del grupo Aggregatum, se comportaron como si fueran del grupo Cepa, al producir pocos bulbos de gran tamaño. La adaptación de los cultivares fue diferente en los ambientes: en campo abierto los cultivares L55 y L63 presentaron los mejores rendimientos, mientras que bajo condiciones protegidas, RPT20 y RPT11 fueron los que mejor se adaptaron. Conclusión. Los ambientes influyeron significativamente en el comportamiento de los cultivares del grupo Aggregatum con una mayor producción de bulbos extragrandes. Los contrastes de temperaturas que se presentaron en los ambientes protegidos con techo plástico, afectaron los rendimientos de los cultivares, mientras que las condiciones ambientales a campo abierto fueron favorables.
