Математическое моделирование отношений агентов организационной системы
Authors: Россихина Л.В. , Бецков А.В. , Макаров В.Ф. , Кондратьев В.Д.
Published: October 2024

В статье рассмотрены основные типы отношений (конфликт, содействие и независимость) активных агентов, проявление которых возможно при их взаимодействии в организационной системе. Под активностью агента понимается возможность самостоятельного целеполагания, в соответствии с которым им осуществляется выбор действий и его недобросовестное поведение. Для характеристики активных агентов введено понятие функция полезности, которая определяет выбор агентом действий, позволяющих его полезность сделать максимальной. Как правило, это прибыль. Приведена математическая формализация отношений активных агентов для варианта достижения общей цели организационной системы, а также с учетом достижения локальных целей активными агентами. Для описания взаимодействия активных агентов в процессе достижения общей цели предложена матрица состояния организационной системы, позволяющая выявить существующие ядра конфликта, независимости и содействия между активными агентами. Элементами матрицы являются количественные оценки множества отношений агентов. Для определения количественных оценок множества отношений агентов разработан алгоритм, основанный на вычислении относительной невязки функций полезности, позволяющий определить характер и степень отношений агентов. Предложена авторская классификация отношений агентов по степени их проявления. Приведен пример, иллюстрирующий практическую реализацию алгоритма.

The article discusses the main types of relationships (conflict, assistance and independence) active agents, the manifestation of which is possible when they interact in the organizational system. The agent's activity is understood as the possibility of independent goal-setting, according to which he chooses actions and his unscrupulous behavior. To characterize active agents, the concept of a utility function is introduced, which determines the agent's choice of actions that allow its usefulness to be maximized, as a rule, this is profit. The mathematical formalization of the relations of active agents is given for the option of achieving the common goal of the organizational system, as well as taking into account the achievement of local goals by active agents. To describe the interaction of active agents in the process of achieving a common goal, a matrix of the state of the organizational system is proposed, which allows to identify the existing cores of conflict, independence and assistance between active agents. The elements of the matrix are quantitative estimates of the set of agent relationships. To determine quantitative estimates of the set of agent relationships, an algorithm based on the calculation of the relative discrepancy of utility functions has been developed, which allows determining the nature and degree of agent relationships. The author's classification of agent relations according to the degree of their manifestation is proposed. An example illustrating the practical implementation of the algorithm is given.
Two Case Presentations with Unexpected Outcomes after Childhood Trauma
Authors: Okružnik Želalić Marta , Želalić Sven
Published: October 2024

Bowlby developed the theory of attachment, describing it as a lasting emotional bond between human beings, manifested by seeking proximity to caregivers, especially in times of distress. Children adjust their behavior to prevent separation from their primary attachment figure – someone who provides support, protection and care. Attachment theory provides a favorable framework for understanding our two cases and their developmental paths.We report two cases of female individuals, both of whom had a family history of psychiatric disease and experienced early parental separation with the grandparents playing significant roles in their upbringing. The two cases had radically different outcomes: one was diagnosed with schizophrenia and the other with generalized anxiety-depressive disorder. We attempt to analyze the reasons for the disparate outcomes of these two cases through the framework of numerous published studies that highlight protective and risk factors for psychiatric disease, studies that highlight the impact of traumatic events in childhood on a child’s biological, psychological and social development, as well as through the lens of psychodynamic and attachment theories. Throughout the analysis, the importance of early intervention is made clear: both through various treatment modalities and preventive measures, as well as by providing successful mental health programs directed towards the destigmatization of children with mental health problems.
Posttraumatic Growth in War Captives
Authors: Jukić Melita , Đuričić Vanja
Published: October 2024

Numerous studies have investigated the various consequences of traumatic experiences during the war. The most significant disorder that occurs as a result of war traumatization is posttraumatic stress disorder, in addition to which other psychological disorders often can occur. In the last few decades, the number of studies researching the occurrence of posttraumatic growth as a positive outcome of trauma, including that of war veterans, has been growing. Among war veterans, prisoners of war stand out for the intensity of their traumatic experience but also for the appearance and intensity of the pathological outcomes of the trauma. Studies show that in this group of veterans, posttraumatic stress disorder and comorbidity disorders often persist for decades after their release from captivity.There is not much research about the positive outcomes of trauma in these particularly vulnerable populations, and this paper is a review of several different studies, the results of which show that posttraumatic growth is possible even after challenging traumatic experiences such as war captivity.
Highly Z-selective Julia–Kocienski Olefination Using N-sulfonylimines and Its Mechanistic Insights from DFT Calculations
Authors: Chizaki Takuma , Fujiwara Koichi , Fujimoto Junko , Narumi Tetsuo , Shuto Satoshi , Watanabe Mizuki
Published: October 2024

The Julia–Kocienski (JK) olefination is a reliable method for E-selective olefination; however, highly Z-selective variants are scarce. Here, we report a highly Z-selective JK olefination (with a Z ratio up to >99:1) using N-sulfonylimines as the electrophilic partners instead of aldehydes. This method showed broad substrate tolerance, accommodating various functional groups, including electron-donating/withdrawing groups, amides, halogens, carboxylic acids, and hydroxyls. DFT calculations revealed that Z-selectivity is determined mainly during the 1,2-addition step. This study enhances the toolkit for Z-selective olefination in organic synthesis.
Modeling the pre-oxidation stage of firefly bioluminescence mechanism
Authors: Blinova Anastasia , Grigorenko Bella
Published: October 2024

Here we present the first stage in the firefly luciferase (FLuc) chemiluminescence pathway, namely the mechanism of the reaction of luciferin with ATP and subsequent deprotonation of the formed luciferyl adenylate. For this purpose, we manually reconstructed the structure of the luciferin-ATP-Mg2+ complex from the luciferin-AMP-Mg2+ structure (PDB ID: 6K4D) and then performed structure refinement using classical molecular dynamics (MD) and quantum mechanics/molecular mechanics (QM/MM) methods. Based on our simulation we depict the roles of amino acids in the active site involved in the formation of the enzyme-substrate complex and the pre-oxidation steps of bioluminescence reaction. By QM/MM approach, we show that the adenylation reaction proceeds via an associative mechanism and leads to luciferyl adenylate, which is easily deprotonated and releases a proton either to His244 or to the pyrophosphate PPi formed during adenylation. Thus, we provide evidence that in the luciferin-AMP-Mg2+ complex, the luciferyl adenylate is already in a deprotonated state, which is confirmed by the crystal structures of this complex.
Oxygen Isotope Fractionation of O2 Consumption Through Abiotic Photochemical Singlet Oxygen Formation Pathways
Authors: Pati Sarah G. , Brunner Lara M. , Ley Martin , Hofstetter Thomas B.
Published: October 2024

Oxygen isotope ratios of O2 are important tracers for assessing biological activity in biogeochemical processes in aquatic environments. In fact, changes of 18O/16 O and 17O/16 O ratios of O2 have been successfully implemented as measures for quantifying photosynthetic O2 production and biological O2 respiration. Despite evidence for light-dependent O2 consumption in sunlit surface waters, however, photochemical O2 loss processes have so far been neglected in the stable isotope-based evaluation of oxygen cycling. Here, we established the magnitude of O isotope fractionation for abiotic photochemical O2 elimination through formation of singlet O2, 1O2, and the ensuing oxygenation and oxidation reactions with organic compounds through experiments with rose bengal as 1O2 sensitizer and three different amino acids and furfuryl alcohol as chemical quenchers. Based on the kinetic analysis of lightdependent O2 removal in the presence of different quenchers, we rationalize the observable O isotope fractionation of O2 and the corresponding, apparent 18O kinetic isotope effects (18O-AKIE) with a pre-equilibrium model for the reversible formation of 1O2 and its irreversible oxygenation reactions with organic compounds. While 18O-AKIEs of oxygenation reactions amount to 1.03, the O isotope fractionation of O2 vanishes systematically with increasing ratio of the rates of oxygenation reaction of 1O2 vs. 1O2 decay to ground state oxygen, 3O2 . Our findings imply that O isotope fractionation through photochemical O2 consumption can match contributions from biological respiration at typical dissolved organic matter concentrations of lakes, rivers, and oceans and should therefore be included in future evaluations of biogeochemical O2 cycling.

Published: October 2024

Synthetic cells have emerged as a promising tool for understanding cellular processes and developing novel biotechnological applications. In this study, we engineer dynamic and biomimetic behaviours in polymersomes, aiming to create synthetic cells that mimic key biological functions. These vesicles exhibit a temperature-driven fusogenic property, enabling the transformation of nanoscale vesicles into microsized sponge-like polymeric droplets. These droplets, rich in membrane content, can act as synthetic cells analogues with the capability for controlled cargo release. Moreover, the thermoresponsive nature of our polymersomes makes them versatile components for the construction of lipid-based synthetic cells, allowing for controllable cargo release and dynamic organelle-like functionalities. We also demonstrate that the microscale polymer droplets possess biomimetic properties including contractility, a behaviour typically observed in biological systems. By modulating the temperature, it is possible to induce these contractile behaviours as well as other functions, including controlled fusion and efficient bacteria capture.

Deuterated compounds used in drug discovery and live-cell imaging have recently gained the attention of various scientific fields. Although hydrogen-deuterium (H/D) exchange reactions are straightforward deuteration methods, achieving perfect regioselectivity is challenging. We report the highly regioselective deuteration of alpha-thio C(sp3)-H bonds using a thioxanthone or anthraquinone organic photocatalyst bearing an aromatic ketone skeleton and D2O as an inexpensive deuterium source under 390-nm irradiation. Notably, deuterium incorporation at the alpha-positions of O/N atoms, benzylic positions, and aromatic rings was not observed. The present regioselectivity was accomplished via a single electron transfer mechanism between the photocatalyst and S-containing substrates, as proven by laser-induced time-resolved transient absorption spectroscopic measurements. Furthermore, the proposed deuteration method could be applied to various S-containing substrates including pharmaceuticals and biologically active compounds with high regioselectivities. The available deuterated compounds as novel deuterated alkylation reagents for future drug discovery and as materials for Raman imaging were also demonstrated.
A Machine Learned Potential for Investigating Single Crystal to Single Crystal Transformations in Complex Organic Molecular Systems
Authors: Zhao Chengxi , Liu Honglai , Qu Da-Hui , Cooper Andrew , Chen Linjiang
Published: October 2024

The packing of organic molecular crystals is often dominated by weak non-covalent interactions, making their in-situ rearrangement under external stimuli challenging to understand. We investigate a pressure-induced single-crystal-to-single- crystal (SCSC) transformation between two polymorphs of 2,4,5-triiodo-1H-imidazole using machine learning potentials. This process involves the rearrangement of halogen and hydrogen bonds combined with proton transfer within a complex solid- state system. We developed a strategy to progressively approach the transition state along the phase transition path from both ends by using both the α and β crystal phases as initial structures for active learning. This method allowed us to develop a DFT-based machine learning potential that faithfully describes both of the stable phases and the transition processes. Our results demonstrate that these anisotropic interactions are represented accurately during molecular dynamic simulations. Bond breaking and reforming during proton transfer is observed and analysed in detail. This approach holds promise for simulating SCSC transitions in organic molecular crystals that involving anisotropic interactions and chemical bond changes.
A Multiresonant Thermally Activated Delayed Fluorescent Dendrimer with Intramolecular Energy Transfer: Application for Efficient Host-Free Green Solution-Processed Organic Light-emitting Diodes

Published: October 2024

The development of narrowband emissive, bright, and stable solution-processed organic light-emitting diodes (SP-OLEDs) remains a challenge. Here, we present a strategy that merges within a single emitter a TADF sensitizer responsible for exciton harvesting and a MR-TADF motif that provides bright and narrowband emission. This emitter design also shows strong resistance to aggregate formation and aggregation-cause quenching. It is based on a known MR-TADF emitter DtBuCzB with a donor-acceptor TADF moiety consisting of either tert-butylcarbazole donors (tBuCzCO2HDCzB) or second-generation carbazole-based donor dendrons (2GtBuCzCO2HDCzB) and a benzoate acceptor. The TADF moiety acts as an exciton harvesting antenna and transfer these excitons via Förster resonance energy transfer to the MR-TADF emissive core. The SP-OLEDs with 2GtBuCzCO2HDCzB and tBuCzCO2HDCzB thus showed very high maximum external quantum efficiencies (EQEmax of 27.9 and 22.0%) and minimal efficiency roll-off out to 5000 cd m-2.

Supramolecular assemblies found in nature demonstrate the concept of creating functionality through structure formation. In recent years, these complex natural architectures have inspired the development of materials for the formation of synthetic nanostructures within living cells. These intracellular assemblies have the potential to modulate cellular processes, yet their specific effects on cellular metabolism and three-dimensional (3D) cell networks, such as tumor spheroids, still remain underexplored. Herein, we correlate the glutathione-induced formation of synthetic nanostructures inside MDA-MB-231 triple negative breast cancer cells to the metabolic disruption and mitochondrial degradation observed in two-dimensional (2D) cell culture, as well as to cell death and size decrease in a three-dimensional (3D) tumor spheroid model. In 2D cell culture, material-cell interactions were examined through live-cell imaging and by quantifying changes in mitochondrial respiration. By studying the interplay between glutathione-responsive cytosolic peptide assembly and the implications on the integrity of the mitochondrial network, as well as on 3D cell networks, our work advances the understanding of how synthetic intracellular nanofibers impact vital functions of living cells.

EGALITARIANISM WITHOUT CATASTROPHE?
Authors: Marienbach Matthieu
Published: October 2024

This paper explores the Teotihuacan civilisation’s low levels of inequality, challenging Walter Scheidel’s Four Horsemen theory which posits that only catastrophic events can significantly reduce inequality. Analysing Teotihuacan, a large pre-Columbian city noted for its egalitarian structure, the paper refutes the idea that only mass warfare, pandemics, revolution or state collapse can flatten social hierarchies. It suggests that Teotihuacan’s unique formation and governance, influenced by a multiethnic population influx following a volcanic eruption, fostered a decentralised and egalitarian society. The paper contributes to the discussion on designing equal and sustainable societies, offering an alternative historical perspective to the inevitability of social inequality.

Published: October 2024

The article analyzes the dynamics of professional identity in psychology students depending on their deep convictions. On a sample of 302 subjects, using the methods of “SEI-test” by E. L. Soldatova, “Crisis Identity Questionnaire”, “Methodology for studying professional identity statuses” by A. A. Abzel, the Rogers-Diamond method and the method of “Diagnostics of irrational attitudes” by A. Ellis, the authors highlight the features of identity formation depending on the severity of deep convictions (Catastrophization, Should-be, Evaluative attitude, Frustration tolerance, etc.). It turned out that the dynamics of identity statuses in general and its professional component are influenced by the Evaluative attitude and General rationality, and the dynamics of the identity crisis - by Catastrophization. The specifics of the influence of deep convictions in first-year and senior students are described. Assumptions are made about the causes of such dynamics and its cofactors.

The article gives a theoretical confirmation and empirical evidence for the correlation of psychological wellbeing and personality health resources of older persons in the context of the existential approach. Personality resources related to the existential framework, which make possible for older persons to stay healthy, have been identified. The study has found that the elderly having a feeling of psychological well-being (existential fulfillment) have more pronounced: 1) urge to actualize personality resources (subjective orientation, self-change potential, viability), 2) inclination to highly assess their energy capacities, and 3) satisfaction with their living on the whole. The results demonstrate the perspectives of psycho-diagnostic assessment of personality health resources of older persons within the framework of the existential approach.

The prevalence of diabetes is increasing globally, necessitating efficient methods to enhance the timely identification and treatment of diabetes, Focusing on early detection and effective management strategies for complications is essential. This study presents an integrated solution comprising two modules: diabetic detection and diabetic retinopathy detection. The diabetic detection module employs machine learning techniques like decision trees, random forests, and KNN for forecasting presence of diabetes based on patient data. The diabetic retinopathy detection module utilizes deep learning techniques, specifically the ResNet50 model architecture, to analyze retinal images and identify signs of diabetic retinopathy. A comprehensive implementation of both modules, including data preprocessing, model training, and evaluation, using Python libraries such as TensorFlow, Keras, and scikit- learn. The trained models are then integrated into a web application. This web application allows users to input their medical data and retinal images, and receive real- time predictions regarding their diabetic status and risk of diabetic retinopathy. The integration of these modules into a web application provides an intuitive interface tailored for both healthcare professionals and patients to assess diabetic risks conveniently. Furthermore, it facilitates early intervention and management of diabetic complications, ultimately improving patient outcomes and reducing healthcare burdens.

O objetivo deste estudo foi avaliar o desempenho de estimadores de precipitação em relação aos dados observados por pluviômetros no leste da Amazônia, abrangendo os estados do Pará, Tocantins e Maranhão no período de janeiro de 2017 a dezembro de 2021. Como referência, foram utilizados dados de precipitação provenientes da Agência Nacional de Águas, do Instituto Nacional de Meteorologia e do Instituto Tecnológico Vale, compondo ao todo 14 postos de medida. As estimativas de precipitação avaliadas foram provenientes dos produtos CHIRPS, CMORPH-HR, CMORPH-BLD, ERA5 e GSMAP, em uma resolução espacial de 0,25° de latitude e longitude. Foram calculadas as médias diária, mensal e anual para comparação subjetiva; e os coeficientes de Nash-Sutcliffe, coeficiente de exatidão, e correlação de Pearson, índice de desempenho e BIAS, para uma análise objetiva. Os resultados mostraram que a maioria dos estimadores subestimaram a precipitação, exceto o CHIRPS. Foi observado que na média mensal a precipitação apresentou melhores estimativas no período seco. Sendo o CMORPH-BLD entre os produtos que apresentou o melhor desempenho baseado nos índices. As diferenças encontradas entre as estimativas de precipitação mostram a importância de avaliações deste tipo, de forma que podem permitir a escolha das estimativas mais adequadas e de forma mais criteriosa em caso de ausência ou falha no conjunto de dados. A topografia e a proximidade do litoral podem ter sido fatores que influenciaram na acurácia das estimativas de precipitação no leste da Amazônia.

A queima de resíduos sólidos é uma técnica irregular que tem como objetivo eliminar resíduos de forma inadequada, sem segregação ou qualquer outro tipo de separação dos resíduos. É possível definir queimadas como práticas realizadas em áreas de pastagem, de florestas e demais áreas, com objetivo de “limpar” o ambiente ou eliminar algum material indesejado. A prática irregular de queimadas, ocasionadas pela coletividade, traz prejuízos à saúde populacional e aos atributos ambientais. Para a avaliação dos focos de queimas e elaboração do mapa de calor foram aplicadas técnicas de geoprocessamento do software livre QGIS versão 3.26, que foram responsáveis por tratarem das imagens espaciais fornecidas pelos satélites Landsat 8 e satélites Acqua, ambos disponíveis no banco de dados do Instituto Nacional de Pesquisas Espaciais (INPE) nos anos de 2018, 2019 e 2020. Para a elaboração dos Mapas de Calor foi utilizada a metodologia conhecida como “Mapa de Densidade de Kernel”. Segundo Rizzatti et. al., (2020) a densidade de Kernel parte do princípio de quantificar e catalogar as relações de pontos sobre um raio ® de influência.Através dos dados obtidos sobre as queimadas na área de influência do antigo lixão, pode-se concluir que após o encerramento do lixão do Timbuba/Pau-deitado, as práticas de queimadas foram aos poucos sendo paralisadas, uma vez que em entre 2018 e 2020 a presença dos focos diminuíram consideravelmente.

O trabalho teve como objetivo avaliar as relações existentes entre os elementos do clima e a sazonalidade de índices de perigo de incêndios e da ocorrência de focos de calor, em três bacias hidrográficas da região Sudeste da Amazônia, afluentes do rio Xingu. Foram avaliados os índices de perigo de incêndio de Angstrom, FMA+ e P-EVAP, com dados meteorológicos diários de 63 estações meteorológicas automáticas da rede de estação do Instituto Nacional de Meteorologia (INMET) e do Agritempo/EMBRAPA, entre os anos de 2017 e 2021. As bacias hidrográficas dos rios Culuene, Comandante Fontoura e Fresco apresentaram sazonalidade climática semelhante, com estação chuvosa entre outubro e abril, e estação seca entre maio e setembro. Dessa forma, os índices de perigo de incêndio demostraram comportamento sazonal semelhante. O índice de Angstrom demonstrou que entre junho e setembro, o número de dias com perigo de incêndio é igual ou superior a 84%. O índice FMA+, apontou que nesse mesmo período, 100% dos dias, independentemente da bacia hidrográfica, estão nas classes de perigo alto e muito alto. O índice P-EVAP, revelou que entre junho e agosto, 97,43% dos dias apresentam perigo alto ou muito alto de incêndio. Os focos de calor estiveram concentrados nos meses de estiagem para as bacias hidrográficas dos rios Culuene (92,8%), Comandante Fontoura (70,9%) e Fresco (89,1%). Dentre os três índices analisados, o índice de perigo de incêndio P-EVAP, conforme os valores do Skill Score e da porcentagem de sucesso exibiu os melhores resultados.

As mudanças climáticas estão anualmente afetando a ocorrência, duração e intensidade dos eventos fenológicos das espécies vegetais. Neste trabalho foi testada a hipótese de que as alterações na ocorrência e sincronia da fenologia reprodutiva de Cenostigma macrophyllum Tul. estão associadas às variações anuais e sazonais do clima. O estudo foi realizado durante 24 meses em remanescente de floresta estacional semidecidual no Piauí, nordeste do Brasil. Foram feitas observações das fenofases de botões florais, floração, frutificação e deiscência dos frutos em 15 indivíduos da espécie. Foi estimada a intensidade e atividade de cada fenofase. Análises estatísticas circulares foram utilizadas para inferir o comportamento sazonal e a sincronia fenológica da espécie. A floração da espécie foi sazonal e síncrona, iniciando no final da estação seca. A frutificação apresentou padrão contínuo, porém seguido por apenas um episódio de floração em cada ano. Os frutos entraram em processo de deiscência na estação seca, findando no início da emissão de novos botões florais. A floração correlacionou ao aumento da precipitação, enquanto a redução das chuvas, redução da umidade relativa do ar e o aumento da temperatura correlacionaram à deiscência dos frutos. Observamos variações anuais nos picos de intensidade da floração e frutificação, embora a deiscência dos frutos tenha se mantido sincronizada entre os anos. Mudanças nos padrões fenológicos ao longo dos anos suscitam preocupações, sobretudo considerando as mudanças climáticas em curso, que têm o potencial de afetar a sincronia das populações da espécie e, consequentemente, seu sucesso reprodutivo.

Poales é uma ordem do clado das monocotiledôneas que apresenta famílias de grande importância econômica e ecológica como Poaceae, Bromeliaceae e Cyperaceae. Apesar de sua relevância, há escassez de estudos voltados a Poales, principalmente em regiões consideradas de baixa biodiversidade. Assim, objetivou-se através deste estudo realizar um levantamento das coletas de espécies de Poales na Região Centro-Sul do estado do Ceará. As informações sobre as coletas e a diversidade dos grupos foram obtidas através da Flora e Funga do Brasil e da rede speciesLink. Dados complementares sobre origem, endemismo, status de conservação das espécies, também foram levantados. Foram registradas 295 coletas de 92 espécies pertencentes a quatro famílias (Bromeliaceae, Cyperaceae, Poaceae e Typhaceae), sendo Poaceae a que possui mais registros. Observou-se que as coletas estão concentradas em Iguatu, enquanto a maioria dos demais municípios apresentou três ou menos coletas. Quatro municípios não apresentaram coleta de Poales: Antonina do Norte, Orós, Tarrafas e Umari. A coleta mais antiga data do ano de 1893 e a maioria das coletas se concentra na década de 2010. A maioria das exsicatas consultadas (ca. 74%) encontram-se depositadas no EAC – Herbário Prisco Bezerra. O baixo número de coletas realizados na Região Centro-Sul Cearense possivelmente se deve à escassez de especialistas em Poales e à presença de áreas ainda não exploradas e subamostradas. Os dados sugerem que a região se apresenta como um campo promissor para futuras pesquisas em florística e taxonomia das famílias de Poales.

A fava (Phaseolus lunatus L.) é uma leguminosa cultivada em todas as regiões do Brasil, sobretudo na região Nordeste, em que apresenta maior produção. O objetivo desta pesquisa foi realizar a identificação dos caracteres morfológicos e agronômicos de 15 genótipos de fava cultivados em diferentes municípios do estado do Ceará, para obtenção de informações sobre os descritores que possam contribuir para estudos de caracterização e variabilidade genética desta cultura. Os ensaios foram conduzidos na área experimental do Laboratório de Ecofisiologia Vegetal (ECOFISIO) da Universidade Estadual do Ceará (UECE), em Fortaleza–CE. Analisaram-se 38 descritores para identificação e caracterização dos genótipos estudados. Observou-se que os descritores peso de cem sementes, comprimento e largura das sementes foram os que mais contribuíram para a variabilidade genética dos genótipos analisados. Os genótipos BF 304, BF 308 e BF 312 foram os que apresentaram maiores valores para estes parâmetros, tornando-se os genótipos promissores para o melhoramento genético. Os aspectos botânicos que permitiram diferenciar os genótipos analisados foram cor e forma do tegumento; cor do hipocótilo e dos cotilédones; textura da testa; cor das nervuras e presença de antocianinas das folhas primárias; cor da folha; forma do folíolo central; cor da quilha e das asas na inflorescência; forma do ápice, curvatura e cor da vagem. Desta forma, conclui-se que a análise destes descritores é importante na diferenciação e determinação de cultivares de fava mais produtivas no estado do Ceará, visto que há informações escassas sobre a diversidade genética e o potencial agronômico desta cultura no Brasil.

Following the 2022 Population Census, the first assessment of Serbia's official population projections based on data from the 2011 Census and other vital statistics and migration sources has become feasible. According to the Census results, the population of Serbia in 2022 is approximately 2.3% below the projected values for that year, according to the closest projection variant – the constant variant. This paper explores the differences in terms of projected and realized values of fertility, mortality, and migration balance. Hypotheses regarding the total fertility rate and the number of live births were largely confirmed. However, a notable deviation was observed in mortality rates, primarily attributed to the COVID-19 pandemic period, during which life expectancy decreased by nearly two years. Apart from the pandemic's effect, the deviation between projected and realized population values is also due to the assumption of a positive migration balance for the period 2011-2022. Contrary to this optimistic assumption, the vital statistics method reveals negative external migration during this period.

En este trabajo se presentan los resultados provenientes de la obtención y caracterización de muestras de acero de bajo carbono AISI 1018, aluminizadas por inmersión en caliente. Las piezas recubiertas fueron caracterizadas mediante microscopía electrónica de barrido, microsonda, microdureza Vickers y ensayos electroquímicos de polarización en una solución de cloruro de sodio. Algunas piezas de acero 1018 aluminzadas por inmersión en caliente se sometieron a diversos tratamientos de recocido, de laminación y de laminación y recocido. Dichas piezas, adicionalmente, se caracterización mediante ensayos de tracción y de embutido para generar el diagrama de conformación límite de las muestras revestidas y sometidas a los diversos procesamientos. Los resultados obtenidos muestran la excelente resistencia a la corrosión de los recubrimientos y la influencia de la presencia de compuestos intermetálicos Al-Fe en la disminución de la conformabilidad de los revestimientos.
