Psychophysiological changes are common factors contributing to the development of arterial hypertension. The aim of this study was to examine the psychophysiological characteristics of individuals with different levels of blood pressure (BP), to build and compare the predictive accuracy of a classical neural network and a Kolmogorov-Arnold network in forecasting BP levels, as well as to determine the prognostic value of the studied psychophysiological parameters. The study involved 240 practically healthy individuals aged 18 to 22. All participants underwent initial BP measurements, based on which they were divided into three groups according to the recommendations of the European Society of Cardiology. The research included 24-h BP monitoring, an assessment of anxiety levels, and evaluations of well-being, activity, mood, and sleep quality. Predictive models were created from the obtained data to forecast systolic BP levels >130 mmHg. Situational and trait anxiety levels were found to be significantly higher in individuals with normal-high BP compared to those with normal-low and normal BP levels. Sleep quality, measured by the PSQI (Pittsburgh sleep quality index) questionnaire, was significantly lower in individuals with normal-high BP compared to the other groups. The neural network constructed in this study demonstrated that psychophysiological indicators can be effectively used for predicting elevated BP levels and for the early diagnosis of arterial hypertension. This research is the first to apply the Kolmogorov-Arnold network for predicting high BP levels. The study found that this network was highly effective, outperforming the multilayer perceptron with a larger number of neurons in terms of predictive accuracy.

The modern scientific direction in the study of the pathogenesis of primary glaucoma is searching for specific biomarkers and regulatory mechanisms of this disease. The aim of the work was to study the level of hydrogen sulfide in eye tissues in animals with adrenaline-induced glaucoma (AIG) and its relationship with intraocular pressure (IOP). The glaucoma model (first group) was induced by injecting 0.1 ml of adrenaline solution into the ear vein for 3 months. In the second group, animals (during AIG simulation) received a hydrogen sulfide donor - daily instillations of 1% NaHS solution into the eye. The third (control) group consisted of intact animals. After 3 months, the level of endogenous hydrogen sulfide was determined in the tissues of the drainage zone of the eye, retina, optic nerve, and intraocular fluid. Glaucoma modeling in rabbits was characterized by a dynamic increase in IOP. A decrease of hydrogen sulfide level in all eye tissues in glaucoma was established. The maximum decrease was observed in the retina by 37.3% when compared with the control. In the second group, the level of endogenous hydrogen sulfide was higher than in the first group in the tissues of the drainage zone by 54%, the retina by 42%, the optic nerve by 37%, and the intraocular fluid by 60%. A decrease and gradual normalization of IOP were found in the second group. The presence of an inverse Spearman correlation between IOP indicators and the level of hydrogen sulfide in all experimental groups was established. We suggest that the established facts confirm the hypothesis regarding the role of a gas transmitter hydrogen sulfide in the pathogenesis of glaucoma.

Existing data suggest the involvement of cytoskeletal proteins, particularly actin, in the process of apoptosis. However, the exact role of actin remains unclear. The aim of this study was to investigate the potential functional interaction of this protein with one of the key participants in apoptosis, cytochrome c. We utilized fluorescent labeling of amino acid residues of rat brain-derived b/g-actin in its monomeric form (G-actin) using the fluorescent dye 3-(4-carboxybenzoyl) quinoline2-carboxaldehyde (CBQCA) to monitor induced molecular changes. It is well known that CBQCA reacts with primary amines in the presence of cyanide to form a fluorescent product. However, we also discovered the formation of another fluorescent derivative when the dye reacted with the phenolic group of free tyrosine, as well as its residues in peptides and proteins, independent of cyanide presence. During the investigation of conformational changes in labeled G-actin molecules, we found that the fluorescence intensity varied in the spectral region characteristic of the reaction product with tyrosine residues, but not with amine groups. Specifically, cytochrome c at micromolar concentrations decreased fluorescence in a dose-dependent manner, indicating direct interaction with G-actin. Actin-specific toxins and other factors affecting its polymerization also reduced the fluorescence intensity of labeled actin, without significantly influencing the effect of cytochrome c. At the same time, cytochrome c had no effect on the fluorescence of inactivated labeled actin. Thus, by utilizing the previously undescribed CBQCA labeling of tyrosine residues, we were able to study conformational changes in the actin molecule and establish the interaction of this protein with cytochrome c. It can be hypothesized that actin is involved in apoptosis as a regulator of apoptosome assembly, particularly through its interaction with cytochrome c.
Husserl contra Brentano. Las críticas a la psicología empírica en las investigaciones lógicas
Authors: Fuentalba Rivas Felipe
Published: December 2024

La influencia Brentano en la fenomenología de Husserl es un hecho establecido. Su primera gran publicación (1891) no ocultaba su adhesión al método de Brentano, contra el cual, sin embargo, se rebela en su siguiente obra, las Investigaciones Lógicas (1900/1901), y de modo más explícito en la segunda edición de ésta (1913). Desde entonces se ha enfatizado que la fenomenología surge contra la psicología Brentano como método, pero con frecuencia se pasan por alto otras críticas no menos importantes. Este trabajo indaga en ellas yendo más allá de la cuestión metodológica. Para ello se exponen las ideas de Brentano y luego las críticas de Husserl, matizándolas o corrigiéndolas, cuando es necesario.
Hermann Cohen y la interpretación hegeliana del cálculo diferencial
Authors: Pringe Hernán
Published: December 2024

En este trabajo comparamos la interpretación del cálculo diferencial que Hegel propone en la Ciencia de la lógica con la que Cohen desarrolla en El principio del método infinitesimal y su historia y en la segunda edición de la Teoría kantiana de la experiencia. Si bien ambos filósofos encuentran en el cálculo el principio cualitativo fundante de lo cuantitativo, Cohen sostiene que Hegel no resuelve el problema de la relación entre matemática y ciencia natural.
Rebelión, violencia y metafísica. Para una lectura deconstructiva del pensamiento de mediodía
Authors: Bellocq Santiago
Published: December 2024

En L’homme révolté, Camus realiza un estudio deconstructivo-histórico-metafísico de las posiciones fundamentales de los diversos tipos de revoluciones que han existido hasta su presente. Contraponiendo la rebelión a la revolución, aboga por una nueva forma de existir, hace una propuesta ética anclada no en una filosofía totalizante sino en un pensar afirmativo, agenciante, liberador. Tras analizar la noción de violencia metafísica, tal como aparece en consideraciones de Derrida y Levinas, vemos que también hay en Camus una lectura deconstructiva de la violencia de las posiciones metafísicas e históricas, por lo cual no puede abandonar la metafísica ni la violencia a favor de la no violencia. El “pensamiento de mediodía” queda así suspendido en un doble movimiento que parte desde la violencia originaria y, a la vez que totaliza la existencia en un nuevo modelo de esencia humana, produce su deconstrucción.
A relação Cristo-Espírito, fundamento da Nova Aliança, e o ministério paulino na Segunda Coríntios
Authors: Nef Ulloa Boris A. , Lopes Jean Richard
Published: December 2024

A Segunda Carta aos Coríntios expressa um momento de alta tensão entre Paulo e os coríntios a respeito da credibilidade do seu ministério. O conflito nasce da influência externa de grupos judaizantes. O apóstolo se utiliza desse contexto particular para aprofundar e explicitar a supremacia soteriológica do evento Cristo diante da provisoriedade da Lei Mosaica. Com genialidade retórica e consistência teológica, esforça-se para neutralizar os efeitos provocados pelos seus opositores e busca atrair a comunidade de volta à órbita de seu ministério e, por conseguinte, ao fundamento de seu Evangelho: a centralidade do evento Cristo; experiência capaz de gerar novos homens e novas mulheres reconciliados(as) na graça do Espírito. Neste artigo, apresentam-se alguns aspectos cristológicos, pneumatológicos e escatológicos que fundamentam o ministério e suas implicações eclesiológicas na perspectiva da Nova Aliança.
Perícias sociais no Direito de Família
Authors: Peixoto Gabriela
Published: December 2024

O Código de Processo Civil brasileiro (Brasil, 2015) prevê que, quando necessário, para elucidar situação que extrapole a área de conhecimento da(o) magistrada(o), serão realizadas perícias técnicas. No Direito de Família, as perícias sociais são bastante demandadas e, para além de aportarem nos autos como um elemento de prova, auxiliam nas tomadas de decisão à medida que explicitam as vivências socioculturais e econômicas dos envolvidos. Através de pesquisa bibliográfica, mas sem desprezar o conhecimento prático da autora, que é assistente social do judiciário gaúcho, o presente artigo traz reflexões sobre a interseção entre o fazer profissional do Direito e o do Serviço Social quando da realização de perícias sociais no Direito de Família. Busca-se expor o aparato legal que prevê e norteia a realização de perícias, bem como o arcabouço ético, metodológico e técnico do Serviço Social que direciona e limita as perícias sociais. A conclusão alcançada é a da necessidade de respeito mútuo sobre a expertise de cada trabalhador, bem como a necessidade de conhecimento mínimo acerca da área de atuação dos diferentes profissionais envolvidos no ato pericial.
Examining the sustainability of current account deficits using a probability approach
Authors: Ndzama Nwabisa Florence
Published: December 2024

We propose a novel probability approach to examine the sustainability of the current account balance by generating density forecasts and calculating the probability that the current account balance will be lower than a specified threshold. We define a current account as sustainable by having a low probability of the current account deficit exploding. We use a vector autoregressive model to generate density forecasts up to five years ahead. We apply the method to ten countries that had high current account deficits in the past and find cases with both high and low probability of sustainability. We analyse historical episodes to illustrate the predictive capability of our framework and find that our method would have worked well in the past. We further find that the sustainability risk does not relate to whether the government or the private sector is the main driver of the deficit.
Embracing a network approach in digital transformation: Is it possible to change the strategic paradigm in Bulgaria?
Authors: Bogdanova Margarita , Parashkevova-Velikova Evelina
Published: December 2024

The purpose of the article is to assess the extent to which digital transformation policies in Bulgaria are modernized and receptive to new multi-sectoral reform approaches. Criteria were developed to evaluate the alignment of government documents with one or more strategic paradigms. An analysis was conducted on eight strategic documents related to digital transformation in Bulgaria, developed after 2010. This analysis utilized the Grounded Theory Coding procedure for inductive category development and applied codes from the criteria framework. Atlas.ti software was used for textual analysis, which provided quantitative data on the frequency of codes meeting the defined criteria for each strategic paradigm. The initial document evaluation was complemented by a qualitative content analysis to clarify the criterion-based findings and further explore the influence of different paradigms. In-depth interviews with representatives from public sector organizations confirmed and enriched some of the conclusions drawn during the analysis. The study finds that (1) the traditional approach dominated the early strategic documents but was gradually displaced by New Public Management; and (2) the network approach is insufficiently represented in the vision and strategic goals of Bulgaria's digital transformation process.

The impact of agriculture in Visegrad countries on CO2 emissions using the FMOLS and DOLS methods in an empirical panel data study
Authors: Suproń Błażej
Published: December 2024

The primary aspiration of this paper is to learn about the effects of agricultural energy consumption, agriculture value added, agricultural land and fertiliser consumption on environmental pollution in Visegrad countries. The research employs panel data from long-run models FMOLS and DOLS, covering the period from 1995 to 2020. The study suggests that there is a positive and statistically significant correlation between CO2 emissions from agriculture in Central and Eastern European countries, and factors such as higher energy consumption, increased value from agricultural production, greater fertiliser consumption, and larger arable land areas. The FMOLS and DOLS models’ long-term coefficients suggest that energy consumption in agriculture and crop area are the main factors contributing to the increase in CO2 emissions from agriculture in the studied countries. The study recommends a sustainable energy transformation of agriculture by limiting the use of fossil fuels in agricultural production and reducing share of arable land.

O que pode a escrita de jovens em fandoms?
Authors: Barbosa Ericka Fernandes Vieira , Versuti Andrea Cristina
Published: December 2024

Resumo Investigamos experiências de jovens que compartilham ficções literárias em comunidades digitais de fãs na intenção de desvelar o potencial da produção de textos descentralizada de ordenamentos sociais que ecoam na didática escolar. Para esta pesquisa, adotamos a cartografia e mapeamos atividades, cujos conteúdos consumidos e produzidos seguem a transmidiação que movimenta a cultura da convergência. Porém, nesse percurso, esses jovens alteram seus modos de pensar, de se relacionar e de aprender em rede, adquirindo multiletramentos e formulando o que se compreende por inteligência coletiva. Como resultado, antevemos que a elaboração textual em coautoria abre passagem para um tipo de aprendizagem solidária, em que prevalecem o espírito colaborativo e relações não estratificadas de poder.
Trabalho, violência armada e saúde na visão de professores em uma escola pública no Rio de Janeiro
Authors: Morais Karla Barros de , Souza Katia Reis de , Santos Gideon Borges dos
Published: December 2024

Resumo O presente artigo objetiva problematizar, à luz dos preceitos da saúde do(a) trabalhador(a), as relações entre trabalho e saúde do(a) professor(a) em uma escola pública localizada em território de violência armada, assim como analisar suas estratégias de resistência e defesa coletiva da saúde. Trata-se de pesquisa qualitativa, realizada por meio de entrevistas semiestruturadas por videoconferência, devido à pandemia de covid-19. Utilizou-se a técnica de análise de conteúdo temática, da qual emergiram quatro categorias de interpretação: cenário de guerra e trabalho docente; a saúde e as percepções de quem luta; resistências e estratégias de defesa da saúde; possíveis saídas. Verificou-se que a experiência dos(as) trabalhadores(as) é fundamental para a proteção coletiva da saúde. A violência que atinge o trabalho do corpo docente em território de violência armada configurou-se como forma específica de violência laboral. Os(as) docentes identificaram o diálogo entre escola, comunidade e autoridades de segurança pública como uma solução eficaz para enfrentar a violência no entorno escolar. A construção de reflexões e propostas coletivas despontaram como um caminho profícuo para o trabalho docente, o que reafirma o papel político e social da escola pública como instituição que representa a comunidade e seus(suas) trabalhadores(as).

Published: December 2024

Resumo O presente artigo, que cumpre o papel de texto-comentador do debate, em dossiê temático, sobre o Complexo Econômico-Industrial da Saúde, reforça a crítica a este campo de pensamento e ação política, tomando como base os seus alicerces. Aponta falhas na análise histórica que conforma o seu diagnóstico da realidade contemporânea, indica a fetichização do papel da iniciativa privada (de matriz schumpeteriana) e denuncia o ecletismo teórico que compromete o método e ignora a incompatibilidade, ora para mais ora para menos, entre os autores mobilizados que lhe conferem base. Conclui que a resultante dessas ‘combinações’, na forma do neodesenvolvimentismo, é e tem sido antes um desserviço.
Radiopacity degree of Bulk Fill composite resins
Authors: Nunes Tâmila da Silva Lopes , Falcão Carlos Alberto Monteiro , Silva Daylana Pacheco da , Ferraz Maria Ângela Arêa Leão , Magalhães Wendell Lucas Evangelista
Published: December 2024

ABSTRACT Objective: To verify and compare the radiopacity of four composite resins available in the national market and analyze their compliance with International Standards Organization 4049 guidelines. Methods: Five specimens of each Bulk Fill composite resin were prepared, and radiographs were taken alongside an aluminum step wedge using a digital imaging system. The images were processed using software capable of measuring mean grey values (MGVs), which were then converted to millimeters of aluminum. Statistical analysis was performed (P 0.05). Results: The four tested composite resins showed radiopacity values higher than those of enamel and dentin, standing out the Tetric N-Ceram- Ivoclar Vivadent (11.05 mmAl). All samples are in accord with the ISO 4049 radiopacity standard. The resin Opus Bulk Fill and Tetric N-Ceram were compared to each other, revealing statistically significant differences (p0,05). Conclusion: All materials demonstrated radiopacity values higher than those of dentin and enamel. All samples are in accordance with the International Organization for Standardization 4049 guidelines. More studies should be conducted with the composite resins used in this study due to the limited research involving these specific resins.
In vitro microbiological analysis of bacterial sealing at the interface between abutment and small-diameter implants after mechanical cycling
Authors: Lobo João Paulo Borre , Joly Júlio Cesar , Teixeira Lucas Novaes , Martinez Elizabeth Ferreira
Published: December 2024

ABSTRACT The objective of this in vitro study was to evaluate the bacterial sealing of the abutment interface and implant in the conical connection of the 2.9mm diameter implant. The research used two sets of screw-in / prosthetic abutment (G1 and G2) for analysis. One group (G1) was previously subjected to mechanical cycling, 500000 cycles per sample, receiving a load of 120N with 30° inclination at 2 Hz. For microbiological analysis, each sample was immersed in Escherichia coli suspension and incubated at 37°C. After 14 days, the abutments were separated from the respective implants, the reverse torque values were recorded and the presence of bacterial penetration was evaluated. Student’s t-distribution and binomial tests were used for the statistical calculations, and a significance level of 5% was adopted. There was no significant difference between the reversal torque values and the proportion of turbid broths. There was contamination in 33% samples and in group G1 and 0% in group G2. There was no significant difference between the values of the reverse torque in the evaluated groups and bacterial sealing with or without mechanical cycling (p>0.05). Therefore, the results of this study showed that implants with platform of 2.9 mm were effective in microbiological sealing, independent of the mechanical cycling, evidencing the accuracy and predictability of the system.

Published: December 2024

ABSTRACT Objective: The aim of this study was to evaluate the effect of different restorative materials for use in CAD-CAM on biaxial flexural strength after accelerated mechanical and thermal aging. Methods: Samples were fabricated and divided into two groups: CL (leucite-reinforced ceramic: IPS Empress CAD) and NR (nanoceramic resin: Lava Ultimate). Morphological analysis of the surface was performed using Scanning Electron Microscopy, and chemical analysis was conducted using Energy Dispersive X-ray Spectroscopy on one sample from each group. All samples underwent accelerated aging, initially through fatigue testing using a mechanical cyclic loading machine (200,000 cycles, 15N force, 1Hz rotation speed) in distilled water at room temperature (37°C). Subsequently, thermal aging was carried out in a thermocycler (5,000 cycles, baths at 5°C and 55°C). Results: The CL group exhibited a more diffuse surface, and chemically, it showed the presence of Silicon, Oxygen, Aluminum, Sodium, Potassium, and Calcium. The NR group had a more compact surface and contained the following chemical elements: Oxygen, Silicon, Carbon, Zirconium, Nitrogen, Aluminum, and Sodium. The CL (193.1MPa) showed a higher mechanical strength value than the NR (52.45MPa), which was statistically significant. However, the NR (2.3) exhibited a lower average number of fragments after fracture compared to the CL (5.6). Conclusion: Restorative materials exhibited distinct morphology and chemical composition. These restorative materials had a statistically significant effect on biaxial flexural strength, with leucite-reinforced ceramics being mechanically superior to nanoceramic resin. And the ceramic matrix resin family showed a lower quantity of fragments after fracture compared to the material representing the glass-ceramic family.

Profissionais de saúde devem incentivar essa prática, orientando as famílias e oferecendo suporte contínuo.
The production of Amazonian urban resistance territories: an analysis of Belém, State of Pará
Authors: Vasconcelos André Felipe dos Santos
Published: December 2024

Abstract This paper discusses urban activism, that is, actions of resistance engendered by social movements against socio-spatial inequalities and for the right to the city in Belém, State of Pará, based on the socio-spatial interpretation of their narratives, tactics, and strategies in recent years. We seek to strengthen a geographic theory of urban social movements viewed as a fundamental analytical category for the scalar understanding of the urban crisis that affects several metropolises in the current capitalist context. In addition, we aim to reinforce the importance of dialogue between academia (from a geographic perspective) and social movements (and their struggles for the right to the city), so that they can cooperate in the construction of alternatives increasingly accompanied by greater socio-spatial justice in the production of the urban space.
Reading attributes of the urban space: a possible methodology for urban heritage
Authors: Dias Adriana Fabre , Afonso Sonia
Published: December 2024

Abstract This article proposes the possibility of reading urban space through the methodology presented by Ewing and Clement (2013) in the book Measuring Urban Design. This methodology was applied to a section of the central area of the city of Laguna, State of Santa Catarina, an area listed by the National Institute of Historical and Artistic Heritage in the 1980s due to its historical and cultural relevance. The methodology determines which public spaces in a city are more attractive to human presence compared to others and what the perceptible qualities of these spaces are, as well as how these qualities can be measured. Initial results indicate that the proposed methodology is suitable for identifying and measuring the perceptible qualities of the urban environment, both in urban heritage areas and in other areas.
O processo de esvaziamento industrial da metrópole paulista: restrições, tendências e perspectivas
Authors: Abdal Alexandre , Madio Felipe
Published: December 2024

Resumo Este artigo tem por objetivo apresentar e discutir o conjunto de pressões que, nos últimos 50 anos, vem produzindo um resultado de esvaziamento industrial na Região Metropolitana de São Paulo. Para tanto, formula e propõe a hipótese de trabalho da tripla pressão. Cada uma delas integra um conjunto causal diferente, associado a uma escala também diferente. As três pressões são: 1) desindustrialização em escala nacional; 2) formação da Macrometrópole Paulista em escala regional; 3) assédio do mercado imobiliário para a reconversão de uso em áreas industriais em escala local. Nossos resultados apontam para o diagnóstico de que o esvaziamento industrial que é de longo prazo no município de São Paulo pode estar se espraiando para o seu entorno metropolitano.

Resumo Hub Criativo do Beato é uma infraestrutura voltada à inovação digital da cidade de Lisboa, Portugal, que vem sendo constituída, desde 2016, por um processo que chamo de refuncionalização contínua e flexível de um antigo complexo industrial militar. Também a compreendo como âncora de reabilitação urbana e como dispositivo de representação para uma Lisboa que compete internacionalmente por atração de capitais em contexto de ascensão global da economia digital. Multiplicidade de ideias, experimentações, aberturas a mudanças e adaptações dão o tom dos projetos lá realizados. O artigo busca compreender criticamente os enlaces possíveis entre produção do urbano e economia digital. Trata-se de um estudo de caso derivado de pesquisa qualitativa de caráter explicativo-interpretativo e baseada no modelo grounded theory.
Repurposing of industrial remnants in the city of Rio de Janeiro
Authors: Corrêa Silvia Borges
Published: December 2024

Abstract This article proposes reflections on the processes of deindustrialization and repurposing of former factories, railway stations, and port warehouses, as well as their impacts on the urban space, based on a survey and a mapping of industrial remnants in the city of Rio de Janeiro. The study is grounded on bibliographical and documentary research, and the theoretical framework revolves around the concepts of repurposing, industrial heritage, and industrial remnants. The findings reveal that most repurposed remnants have functions related to culture/art and consumption, while a quarter of the industrial remnants are currently abandoned and without function. It is concluded that, despite the neglect and abandonment of these facilities, there are opportunities to devise pathways for creating new uses for these industrial remnants.
O problema do riso: o primeiro pátio de comédias de Lisboa diante do período filipino e da Restauração Portuguesa (1588-1669)
Authors: Silva Pedro
Published: December 2024

RESUMO Construído em 1588 como um autêntico teatro comercial do Siglo de Oro e em consequên-cia de um alvará de Filipe II, a trajetória do Pátio das Arcas, o primeiro teatro regular de Lisboa, explica-se a partir dos marcos que definem a vida política portuguesa a partir de 1580. Com base nos registros de receita do Pátio e de fontes que documentam algumas reações à presença de um teatro visto como espanhol, este artigo interroga o funcionamento do Pátio das Arcas desde o seu contexto de abertura até a Restauração Portuguesa, a fim de aferir sua interferência no cotidiano de uma cidade que atravessava contingências políticas e culturais que fazem dele um símbolo ainda bastante ignorado do período filipino. Ao fim, demonstra-se como as repercussões da atividade teatral do Siglo de Oro, em Portugal, atestam uma relação direta entre o funcionamento do Pátio das Arcas e os acontecimentos maiores da vida política lusa entre 1580 e 1668.
Oceanographic features in the vicinity of Japaratuba Canyon, Sergipe, Brazil

ABSTRACT This study presents an initial assessment of the hydrographic characteristics in the region of the Japaratuba Canyon on the continental shelf of Sergipe, Brazil. An oceanographic campaign was conducted, during which two high spatial resolution transects were made on the north and south sides of the canyon, along with a transverse transect. The results indicate that the hydrographic features are similar to those found on the continental shelf of Pernambuco, with the dominant water mass being Tropical Water. However, it differs in having a much greater influence from Coastal Water, as a result of the dispersion of the São Francisco River plume to the south and from small rivers that discharge into the northern portion of the continental shelf of the state of Sergipe. The near bottom turbidity and chlorophyll were relatively higher in the southern section, what can be an indication that the presence of the canyon can produce a localized upwelling effect, with the canyon playing a role in allowing the approach of water from the top of the nearest permanent thermocline to the coast.
Participação social no ciberespaço: o caso da atenção primária no Twitter em contexto de pandemia

Published: December 2024

RESUMO O estudo analisou postagens no Twitter sobre Atenção Primária à Saúde (APS) a fim de identificar os problemas e as potencialidades referidos pelos usuários. Trata-se de uma pesquisa exploratória, qualitativa e observacional não participante, em que foram coletados 135.855 tweets publicados entre janeiro de 2020 e dezembro de 2021, analisados por meio da Mineração de Textos. Como resultado, do corpus analisado, foram identificadas quatro categorias temáticas não exclusivas, nomeadamente: Acessibilidade e Cobertura; Prestação de Serviços; Gestão e Recursos e Organização do SUS. Cinco modos de participação foram também identificados no debate sobre a APS: a denúncia, o compartilhamento de experiências positivas, a call for action, a accountability e a conscientização (awareness). Na especificidade da pandemia, críticas sistemáticas foram apresentadas relacionadas com as quatro dimensões analisadas. Apesar da existência dos problemas, a maior parte das denúncias não foram feitas de forma a explicitar um SUS-problema, mas um SUS-real. Reitera-se que o ciberespaço precisa ser devidamente apreendido enquanto lócus de investigação, pois ele é apropriado pelas pessoas para expressar suas opiniões e participar da vida cívica avaliando as políticas e os diversos componentes do sistema de serviços de saúde.

Abstract The objective in this study was to determine the duration of the vegetative and the reproductive phases, as the relationship between total developmental cycle and developmental phases in on-farm cut dahlia cultivars. Ten on farm trials using two to eight cut dahlia cultivars during three years (2021 to 2023) at eight locations in the state of Rio Grande do Sul, Southern Brazil, were used. Tubers were planted in beds 1.0 m wide and 0.2 m high, at a 0.40 m x 0.40 m spacing and at a depth of 0.05 m. The date of crop emergence was considered when 50% of the plants had emerged. The main shoot of 10 plants per cultivar was tagged. The number of unfolded leaf pairs on tagged plants was counted until the last pair of unfolded leaves on the main shoot. The date that 50% of the tagged plants were at first visible floral bud on the main shoot and at the first flower on the main shoot with the first layer of petals fully open (harvest point) were collected by observing the tagged plants daily. It was observed that the vegetative phase varied from 14 to 58 days, while the reproductive phase varied from 11 to 48 days, depending on the cultivar and planting date. The duration of the total developmental cycle, from plant emergence to the first flower opening, which is considered the harvest point of the crop, is primarily determined by the duration of the vegetative phase, which, in turn, is related to the phyllochron or leaf appearance rate. These results have practical applications for farmers, consultants, and breeders, such as selecting cultivars for specific regions, optimizing planting dates, planning the harvest, and adjusting management practices.

Published: December 2024

Abstract Heliconia cultivation faces challenges due to diseases that lead to depreciation in flower quality, decrease in yield, and increase in management costs. Quality standards require heliconias to be visually attractive and healthy. The primary causes of these diseases include fungi, nematodes, bacteria, and viruses. Fungal diseases are the most prevalent, causing damage to leaves, bracts, and rhizomes. Nematode-induced diseases affect both underground and above-ground plant organs. Among bacterial diseases, wilt caused by Ralstonia solanacearum is the most damaging to the crop, while viral diseases are relatively rare. Integrated disease management is the best strategy to control diseases in heliconias. This strategy combines preventive, curative, and eradication measures. This study describes the main diseases affecting heliconias, highlighting their primary occurrence sites, host range, as well as the description of disease symptoms and pathogens. Additionally, information on the cycle, epidemiology, and management of the major diseases is provided. The aim is to contribute to the sustainability and efficiency of heliconia cultivation.
