ABSTRACT This study aimed to evaluate the effects of different colors and management of polypropylene non-woven fabric coverings and two different localized irrigation systems on the physiological characteristics and yield of industrial tomatoes. The experiment was installed in a randomized block design arranged in a split-plot scheme with four replications. Surface and subsurface drip were used in the plots, and five plant cover strategies with non-woven fabric in the subplots: i) without non-woven fabric; ii) coverage with white non-woven fabric; iii) coverage with white non-woven fabric, removed between 30 and 60 days after transplanting the seedlings; iv) coverage with red non-woven fabric; v) coverage with red non-woven fabric, removed between 30 and 60 days after transplanting. Photosynthesis, transpiration, electron transport rate, stomatal conductance, carbon concentration, total fruit yield, and water use efficiency were evaluated. ANOVA and the Scott-Knott test were used. Transpiration is favored by the white non-woven fabric and the stomatal conductance by the white and uninterrupted red one. However, the tomato yield is not influenced by the coverings, except for the red one, removed only between 30 and 60 days after transplanting, which is the worst condition for industrial tomato production. Surface and subsurface irrigation can be used with the same efficiency. nonwoven non woven tomatoes splitplot split plot replications plots subplots i ii iii 3 6 seedlings iv v Photosynthesis transpiration rate concentration evaluated ScottKnott Scott Knott one However production

ABSTRACT Objective To evaluate the in vitro and in vivo toxicities of polyethylene glycol-coated gold nanoparticles synthesized using a one-step process. Methods Gold nanoparticles were prepared via a co-precipitation method using polyethylene glycol, and the synthesis product was characterized. For the in vitro evaluation, a flow cytometry analysis with Annexin V and iodide propidium staining was used to assess cytotoxicity in MG-63 cells labeled with 10, 50, and 100µg/mL of nanoparticle concentration. For the in vivo evaluation, nanoparticles were administered intraperitoneally at a dose of 10mg/kg dose in 10-week-old mice. Toxicity was assessed 24 hours and 7 days after administration via histopathological analysis of various tissues, as well as through renal, hepatic, and hematopoietic evaluations. Results Synthesized nanoparticles exhibited different hydrodynamic sizes depending on the medium: 51.27±1.62nm in water and 268.12±28.45nm (0 hour) in culture medium. They demonstrated a maximum absorbance at 520nm and a zeta potential of -8.419mV. Cellular viability exceeded 90%, with less than 3% early apoptosis, 6% late apoptosis, and 1% necrosis across all labeling conditions, indicating minimal cytotoxicity differences. Histopathological analysis highlighted the accumulation of nanoparticles in the mesentery; however, no lesions or visible agglomeration was observed in the remaining tissues. Renal, hepatic, and hematopoietic analyses showed no significant differences at any time point. Conclusion Polyethylene glycol-coated gold nanoparticles exhibit extremely low toxicity and high biocompatibility, showing promise for future studies. glycolcoated glycol coated onestep one step process coprecipitation co precipitation characterized evaluation MG63 MG 63 MG-6 10 50 100µgmL µgmL 100µg mL µg concentration 10mgkg mgkg 10mg kg mg 10weekold weekold week old mice 2 tissues renal hepatic evaluations medium 5127162nm nm 51 27 1 62nm 268122845nm 268 12 28 45nm 0 ( hour 8.419mV. 8419mV mV 8 419mV -8.419mV 90 90% 3 apoptosis 6 conditions mesentery however Renal point biocompatibility studies MG6 MG- 5 26 8.419mV 9

SUMMARY OBJECTIVE: The aim of this study was to evaluate the efficacy of long-term oxygen therapy as a strategy to reduce hospitalization time in patients affected by COVID-19. METHODS: Between April and December 2021, COVID-19 patients with stable clinical conditions needing supplementary oxygen therapy during hospitalization were oriented to have hospital discharge with long-term oxygen therapy and reassessment after 15 days. RESULTS: A total of 62 patients were evaluated and, 15 days after discharge, 69% of patients had suspended long-term oxygen therapy, with no difference between the groups admitted to the intensive care unit or the ward (p=0.319). Among the individuals who needed to maintain long-term oxygen therapy, in addition to worse P/F ratio (265±57 vs. 345±51; p<0.001) and lower partial pressure of oxygen (55±12 vs. 72±11 mmHg; p<0.001), were those more obese (37±8 vs. 30±6 kg/m2; p=0.032), needed more time for invasive mechanical ventilation (46±27 vs. 20±16 days; p=0.029), had greater persistence of symptoms (p<0.001), and shorter time between the onset of symptoms and the need for hospitalization (7 [2–9] vs. 10 [6–12] days; p=0.039). CONCLUSION: Long-term oxygen therapy is an effective strategy for reducing hospitalization time in COVID-19 patients, regardless of gravity. Additionally, more obese patients with persistence of respiratory symptoms, faster disease evolution, and more days of invasive mechanical ventilation needed to maintain the long-term oxygen therapy longer.

Resumo Este artigo analisa estatisticamente os títulos dos artigos publicados na Análise Social (1963-2022), comparando as palavras utilizadas ao longo de seis décadas. Parte-se da premissa de que a escolha de determinadas palavras é reveladora de diversos “mundos do texto”, organizados em função de motivações e interesses distintos. Enunciadas em determinados contextos históricos e mediadas pelo trabalho das sucessivas equipas editoriais, as palavras constituintes dos léxicos da revista mostram linhas de continuidade e mudança temática ao longo do tempo.

Abstract This article analyses, from a statistical point of view, the titles of the articles published in Análise Social (from 1963 to 2022), by comparing the words used over these six decades. Starting from the premise that a certain choice of words reflect a diverse set of “textual worlds”, which are organised according to different motivations and interests, these words, produced under certain historical contexts and mediated by the work of the journal’s editorial teams reveal both the continuity and the thematic changes that shaped its lexicon over time.

Abstract This article presents the development of a liquid-level sensor using fiber optic Bragg gratings (FBG). The sensor comprises a carbon-fiber-reinforced polymers (CFRP) diaphragm packaging an embedded FBG to measure strain. A mathematical analysis determines the FBG response to the pressure exerted by a liquid column over the packaged sensor. The experimental arrangement consists of an acrylic tube with a sensor at the bottom. FBG signals were acquired using a DI 410 optical interrogator manufactured by HBM. A finite element simulation with Ansys was performed to determine the most reposeful position from the FBG sensor. The experimental results show the analysis of eight repetitions of the water column ranging from 10 cm to 60 cm using 10 cm steps. The sensor showed a linear response, with a coefficient of determination of 0.999, and a sensitivity of 4.1 pm/cm; and the maximum standard deviation is 0.64 pm. Although water is used in the calibration process, other liquids could also be used, obtaining a different angular coefficient depending on the density of the liquid used. liquidlevel level FBG. .

ABSTRACT The slope of cultivation channels and types of nutrient solutions in hydroponics and aquaponics influence nutrient absorption and plant production. This research aimed to evaluate lettuce production under different channel slopes and nutrient solutions in hydroponic and aquaponic systems using the nutrient film technique (NFT). A randomized block design was used, with three replicates, in a 3 × 5 split-plot scheme, with three nutrient solutions (conventional hydroponic solution and two wastewaters from the tilapia fish diets, with 15 and 18% of crude protein) and five slopes (2, 4, 6, 8 and 10%) of cultivation channels (PVC tubes). The following variables were evaluated: fresh and dry mass of shoot and roots and the chemical elements of the solutions. In the tilapia feed, the nutrient solution with 18% of protein (wastewater) provides greater production and accumulation of nutrients (N and P) in the lettuce shoot. The slope of 8% on cultivation channels provides greater production of iceberg lettuce, cultivar Lucy Brown. The different slopes and nutrient solutions studied did not influence the potassium (K) accumulation in the lettuce shoot. NFT. NFT .

Abstract The aim of this article is to understand how digital literacies, the usage of digital technologies and emergency remote teaching during the COVID-19 pandemic have affected the life of women participating in stricto sensu Graduate Programs of Universities in the Brazilian Legal Amazon. This study is based on the perspective of digital literacies, which considers the social uses of reading and writing. This is a mixed approach, exploratory and applied research. The data has been collected during August and September, 2021, by means an online platform, based on a 30-item semi-structured questionnaire. The data set comprises 218 valid answers from female professors (n = 100) and students (n = 118) (age 18+) of the surveyed Universities. The results show that the respondents have faced many challenges in emergency remote teaching during the pandemic, in particular, work overload, scarce interaction with colleagues, limitations in the use of digital technologies, difficulties in accessing digital technologies, mental/physical health problems and lack of boundaries between academic and family activities performed in the household environment. Nonetheless, the digital technologies have enabled them to participate in events (livestreams, webinars, conferences, courses), meeting research groups and proceed with classes and research. In a geographically large and economically disadvantaged region, as is the case of the Brazilian Legal Amazon, public policies are essential in order to promote literacy events and activities.

Resumen Este artículo tiene como objetivo comprender cómo las literacidades digitales, el uso de las tecnologías digitales y la enseñanza remota de emergencia durante la pandemia del COVID-19 impactaron en la vida de las mujeres vinculadas a los Programas de Postgrado, stricto sensu, de las Universidades de la Amazonia Legal brasileña. El estudio se basa en la perspectiva de la literacidad digital, que considera los usos sociales de la lectura y la escritura. Se trata de una investigación de enfoque mixto, exploratorio y aplicado. Los datos se recopilaron en los meses de agosto y septiembre de 2021 en una plataforma online, a partir de un cuestionario semiestructurado de 30 ítems. El conjunto de datos presenta 218 respuestas válidas de profesoras (n = 100) y alumnas (n = 118) (de más de 18 años) de las universidades sondeadas. Los resultados evidencian que las personas encuestadas se enfrentaron a muchos desafíos en la enseñanza remota de emergencia durante la pandemia, especialmente por el exceso de trabajo, la poca interacción con las personas colegas de estudios, las limitaciones en el uso de las tecnologías digitales, las dificultades en el acceso a las tecnologías digitales, los problemas de salud mental/física y la falta de límites entre las actividades académicas y del hogar experimentadas en el entorno familiar. A pesar de ello, las tecnologías digitales les permitieron participar en eventos (lives, webinars, congresos, cursos), reunirse en grupos y continuar con las clases y con la investigación. Además, se constató que, en una región geográficamente extensa y económicamente desfavorecida como es la Amazonia Legal brasileña, las políticas públicas son fundamentales para la promoción de eventos y actividades de literacidad.

Apesar disso, as tecnologias digitais permitiram-lhes participar de eventos (lives, webinars, congressos, cursos), reunir-se em grupos de pesquisadores e dar continuidade a aulas e a pesquisas. Em uma região geograficamente extensa e economicamente desfavorecida, como é o caso da Amazônia Legal brasileira, políticas públicas são fundamentais para a promoção de eventos e atividades de letramento.

Abstract The objective of the present study was to analyze the factors that contribute to the demotivation of female students in Physical Education classes in the final years of Ensino Fundamental (elementary and middle school, students aged 6 to 14). This is a qualitative and descriptive study. A semi-structured questionnaire was applied to 53 female students from four schools in the urban area of the city of Iguatu-CE. Thematic content analysis was used for data analysis and interpretation. The results showed that classes taught in reverse shifts, peer rejection, male student aggressiveness, tiredness, lack of interest in the discipline, lack of diversification of content and teaching methods are the main factors related to demotivation. It is concluded that demotivation is characterized by factors that can be reversed with curricular, methodological and organizational actions related to educational policies.

Abstract In this work, measuring capabilities of a Sagnac Interferometer-based Distributed Optical Fiber Sensor (DOFS) system are demonstrated by comparing its results to a conventional amplitude-based Distributed Acoustic Sensing (DAS) system. Through a set of three different experiments, it was demonstrated that both sensing systems can detect and locate dynamical deformation along the fiber, in addition to determining its frequency components. The coherent amplitude-based DAS presented a lower background noise. In contrast, even though the Sagnac interferometry-based system presented low-frequency noise in the measurements, it is less susceptible to harmonic distortion for higher amplitude deformations since its sensing principles rely on the measurement of the accumulated phase rather than the amplitude of the backscattered signal purely. Accordingly, the Sagnac interferometry-based system arises as a promising and rather accessible topology for a DOFS implementation. work Interferometerbased Interferometer based (DOFS amplitudebased (DAS experiments fiber components contrast interferometrybased interferometry lowfrequency low measurements purely Accordingly implementation

ABSTRACT Plant resistance is an important tactic within the precepts of Integrated Pest Management, and the existence of grain sorghum hybrids with multiple insect resistance could benefit crop management and sustainability. This study evaluated the susceptibility of 30 grain-sorghum hybrids to three major pests, namely, fall armyworm (FAW) Spodoptera frugiperda, sugarcane borer (SCB) Diatraea saccharalis, and green-belly stink bug (GBS) Diceraeus melacanthus. The hybrids were cultivated and experiments with each insect species were conducted separately in a greenhouse. For FAW, visual injury assessments were performed on plants 7 and 14 days after infestation (DAI). For SCB, insect presence and injury were assessed 40 DAI. For GBS, the plants were evaluated using a damage rating scale 12, 19, and 26 DAI. Cluster analysis allowed separating the grain sorghum hybrids into groups regarding the levels of resistance to each pest. Hybrid BRS373 stood out as moderately resistant to FAW; AG1090, 80G20, BRAVO, BRS373, AG1615, and IG220 were the most promising for SCB; and for GBS, hybrids 50A40, A9735R, JADE, ENFORCER, BUSTER, 50A10, and IG244 were the most nominated. This information will significantly aid sorghum breeding programs focused on developing commercial hybrids that comprise both insect-resistance and high-yield characteristics. However, further research should evaluate potential chemical and morphological plant traits underlying the lower levels of susceptibility to FAW, SCB, and GBS found in the selected sorghum hybrids.

Abstract This study investigates the system justifying role through belief in a just world (BJW), testing whether institutional trust is related to this belief and whether this relationship depends on specific socioeconomic and political factors. A research with 381 university students, aged 18 to 64 years (M = 22.4, SD = 6.25), explored their BJW and their degree of institutional trust. Regression and moderation analyses revealed that BJW relates to institutional trust only in left-wing and with lower income participants. We believe this occurs because they need more an ideology that justifies the system to trust the institutions. This phenomenon can prevent these people from pursuing structural social changes since the system is now seen as fair.

Resumo Este estudo investiga o papel justificador do sistema através da crença no mundo justo (CMJ), testando se a confiança institucional está relacionada com essa crença e se esta relação depende de fatores socioeconômicos e políticos específicos. Uma pesquisa com 381 universitários, com idades de 18 a 64 anos (M = 22,4, DP = 6,25), explorou seus graus de CMJ e confiança institucional. Análises de regressão e moderação revelaram que a CMJ se relaciona com a confiança institucional apenas naqueles de esquerda e menores rendimentos. Acreditamos que isso ocorra porque estas pessoas precisam mais de uma ideologia justificadora do sistema para poder confiar nas instituições. Este fenômeno pode lhes indispor a buscar mudanças sociais estruturais, já que o sistema passa a ser visto como justo.

Abstract The objective of this work was to evaluate the effect of salinity on Na+ and K+ distribution and on proline content in Urochloa brizantha and Urochloa decumbens grass cultivars. Plants were grown in nutrient solution and subjected to salt stress for nine days. Shoot and root lengths and proline, total chlorophyll, K+, and Na+ contents were determined. Salt stress reduced the shoot length of cultivar Marandu but not of Xaraés and Basilisk. Total chlorophyll content was not affected by salinity in U. brizantha cultivars, but increased in cultivar Basilisk of U. decumbens. Salt-induced proline accumulation was observed in all cultivars, with a higher increase in Marandu. The K+ content in leaf blades increased in the Marandu and Basilisk cultivars under salinity conditions. 'Basilisk' showed Na+ exclusion in shoot tissues, whereas 'Marandu' and 'Piatã', followed by 'Xaraés', exhibited a higher Na+ in leaf blades. The pattern of ion distribution among cultivars was attributed mainly to differences in the ability to control the ion transport from root to shoot, since the rates of ion uptake were similarly affected by salinity. Tolerance to salt stress in grasses of the Urochloa genus is associated to Na+ exclusion and not to proline accumulation in shoot tissues. Na K days determined U Saltinduced induced conditions 'Basilisk tissues 'Marandu Piatã, Piatã , 'Piatã' Xaraés, 'Xaraés' 'Piatã 'Xaraés

Foram determinados os comprimentos da parte aérea e das raízes e os conteúdos de prolina, clorofila total, K+ e Na+. O estresse salino reduziu o comprimento da par te aérea da cultivar Marandu, mas não de Xaraés e Basilisk. O conteúdo total de clorofila não foi afetado nas cultivares de U. brizantha, mas aumentou na cultivar Basilisk de U. decumbens. Observou-se acúmulo de prolina em todas as cultivares sob estresse salino, com maior aumento em Marandu. O conteúdo de K+ nos limbos foliares aumentou nas cultivares Marandu e na Basilisk, em condições de estresse. 'Basilisk' apresentou exclusão de Na+ nos tecidos aéreos, enquanto 'Marandu' e 'Piatã', seguidas por 'Xaraés', apresentaram maior acúmulo de Na+ nos limbos foliares. O padrão de distribuição de íons entre as cultivares foi atribuído, principalmente, a diferenças na habilidade para controlar seu transporte da raiz aos tecidos da parte aérea, já que as taxas de absorção foram similarmente afetadas pela salinidade. A tolerância à salinidade em gramíneas do gênero Urochloa está associada à exclusão de Na+ e não ao acúmulo de prolina na parte aérea da planta.

ABSTRACT In this paper, we analyze literacy practices and representations in the comic books genre produced by undergraduates taking the Rural Education degree. The research is based on literacy theories and is situated in the applied field of language. This is a participatory research, with a qualitative-interpretative approach. The corpus consists of texts from six examples of the comic books genre, and (transcribed) excepts from three interviews conducted with research collaborators. Because this genre has a union of different language systems (verbal and non-verbal), the research revealed traces of literacy that students have in their life experiences. As the research collaborators come from different communities located in rural areas, they present diverse and peculiar literacy practices and representations. paper degree qualitativeinterpretative qualitative interpretative approach transcribed (transcribed verbal nonverbal, nonverbal non , non-verbal) experiences areas non-verbal

RESUMO Neste artigo, analisam-se as práticas e representações de letramento no gênero História em Quadrinhos produzido por alunos de uma Licenciatura em Educação do Campo. A pesquisa alicerça-se nas teorias do letramento, situando-se no campo aplicado da linguagem. Trata-se de uma pesquisa participante, de abordagem qualitativo-interpretativista. O corpus é constituído de textos de seis exemplares do gênero História em Quadrinhos e trechos (transcritos) de três entrevistas realizadas com colaboradores da pesquisa. Por este gênero possuir uma união de sistemas de linguagens diferentes (verbal e não verbal), a pesquisa revelou traços do letramento que os acadêmicos possuem em suas experiências de vida. Sendo os colaboradores da pesquisa oriundos de comunidades distintas situadas no meio rural, eles apresentam práticas e representações de letramento diversas e peculiares. artigo analisamse analisam se Campo alicerçase alicerça situandose situando linguagem Tratase Trata participante qualitativointerpretativista. qualitativointerpretativista qualitativo interpretativista. interpretativista qualitativo-interpretativista transcritos (transcritos verbal verbal, , verbal) vida rural peculiares
