Published: October 2024

Abstract The sedative and anesthetic actions of several essential oils (EO) on fish have been demonstrated, stimulating the search for new options for natural anesthetics. This work evaluated the safety and sedative and anesthetic efficacy of EOs from three native Brazilian plants, Acmella oleracea (jambu), Aloysia hatschbachii and Cordia verbenacea (whale herb) in juvenile Rhamdia quelen (silver catfish). Anesthetic induction and recovery protocols (20 to 400 mg L-1) and long exposure (48 h) from 10 to 100 mg L-1 were tested. The EOs performed sedative and/or anesthetic activities: AOOi at a concentration of 20 mg L-1, AOOl at 50 and 100 mg L-1, AHOl, and CVOL (only sedation) 50 mg L⁻¹, as there were no important adverse effects and/or mortality. The results obtained indicate that Cordia verbenacea EO is the most promising as a sedative for juvenile silver catfish at a concentration of 50 mg L⁻¹.

Authors: Souza Leonardo Santos de , Murgo Camélia Santina
Published: October 2024

Abstract Objective To examine evidence of convergent-divergent validity evidence based on the relationship with external variables for the Teacher Self-Efficacy Scale for the use of Active Methodologies. Method This exploratory cross-sectional study investigated correlations between Teacher Self-Efficacy Scale for the use of Active Methodologies and factors from two other instruments: Well-Being at Work Scale and Maslach Burnout Inventory. A total of 317 professors from different public and private Brazilian universities who use active methodologies participated in this study. Results Teacher self-efficacy was found to be positively correlated with positive affect, achievement/expressiveness and professional achievement and it was negatively correlated with negative affect and emotional exhaustion, showing a significant but weak correlation. According to the path analysis model, personal and professional achievement was predictive of teachers´ self-efficacy to foster active learning. Conclusion The scale is considered to have adequate validity evidence based on the relationship with external variables, and can be used in research in the Brazilian framework.

Authors: Visintin Carolina Del Negro , Ribeiro Letícia Jóia , Vicensotti Stephanie Aragão Lusoli , Granato Tânia Mara Marques
Published: October 2024

Abstract Objective Based on the premise that the diagnosis of a genetic mutation related to breast cancer causes emotional distress for the patient and their family members, a systematic literature review was conducted to clarify this relationship commonly observed in oncologic clinical practice. Method In total, 18 articles confirmed through bias analysis were reviewed. The articles were retrieved from the PubMed, Cochrane Wiley, SciELO, and APA-PsycInfo databases. Results These studies confirmed the hypothesis that a positive result in the genetic test triggers significant distress for both the patient and their family members, although each individual reacts in a unique way. The researchers recommend that the diagnosis should not be considered the sole factor for the studied outcome. It should be related to personal or family history of illness, previous experiences, and previous mental health. Conclusion We conclude, by a slight tendency, to include qualitative studies as a way to evaluate experiences in a more in-depth manner.

Published: October 2024

Resumo Este trabalho objetiva analisar as ações e articulações dos grupos de ativistas “Minha Jampa” e “João Pessoa que Queremos”, que reivindicaram participação na gestão e estratégias de planejamento urbano na cidade de João Pessoa/PB. Para responder a problemática – Como essas redes de ativismos compreendem a cidade? – foram analisadas referências teórico-metodológicas para entender a passagem das interpretações sobre os movimentos sociais e como se desencadeou o processo de concepção dos ativistas urbanos articulados em rede e suas novas realidades. Usando a pesquisa qualitativa, observou-se que as ações coletivas revelaram questões interligadas sobre direito à cidade, na medida em que buscaram exercer algum controle social nas políticas públicas urbanas, principalmente de mobilidade urbana, visto a debilidade das instâncias oficiais de gestão democrática nesse controle. Além do monitoramento na condução de práticas de governo, os grupos de ativistas articulados em rede realizaram investigações e análises críticas sobre os projetos e mudanças nas leis urbanísticas e ambientais que podem ameaçar os direitos na e à cidade. Foi possível constatar que a ação desses grupos propõe novas abordagens e ferramentas para fomentar a participação social ampla, na direção de constituição de uma comunidade política, que constroem coletivamente a cidade para todas as pessoas.

Authors: Freitas Mydiã Falcão , Pires Mônica Moura , Benincá Dirceu
Published: October 2024

Resumo Diversas práticas, classificadas como ações e modelos de gestão social e ambientalmente adequados, definidos na Política Nacional de Resíduos Sólidos (PNRS), vêm sendo empregadas em municípios brasileiros. Todavia, em muitos municípios, são verificadas múltiplas fragilidades no que diz respeito à gestão dos Resíduos Sólidos Urbanos (RSU). Conhecer as fragilidades e potencialidades que os municípios enfrentam é de suma importância para servir como base na busca por soluções sustentáveis e alinhadas às especificidades das realidades locais. A partir dos dados obtidos em textos científicos, foi construída a matriz SWOT (Strengths, Weaknesses, Opportunities, Threats), visando avaliar as forças, fraquezas, oportunidades e ameaças da gestão dos RSU no cenário brasileiro. Os resultados apontam que o Brasil é um país com grande potencial para gerir seus RSU, contudo enfrenta problemas de ordens diversas, que vão desde a ausência de recursos financeiros e de pessoal até a falta de vontade política em priorizar as questões que envolvem os RSU. A partir dos resultados obtidos, foi possível sugerir elementos visando impulsionar as potencialidades e ações para que as fragilidades possam ser superadas. Assim, espera-se que este trabalho auxilie os gestores públicos a construírem planos de ação que possam ser executados com maior eficiência na realidade local.

Authors: Gana-Núñez Alejandro , Orellana Ossandón Arturo
Published: October 2024

Resumen En la actualidad el despoblamiento asume magnitudes dramáticas en contextos como el área mediterránea, en especial en las zonas interiores en España y en las denominadas “áreas internas” en Italia. En América latina este fenómeno, que emerge en las últimas décadas, está siendo estudiado principalmente en su relación con las dinámicas de urbanización y desagrarización, que afectan sobre todo a los países que han experimentado transformaciones sociales y económicas importantes en los territorios rurales, como Chile. Cambios culturales, de expectativas de vida, pero también transformaciones en la estructura económica y productiva en contexto rural, son relevantes para comprender la pérdida de población. En el artículo se aborda esta problemática a través de análisis de datos cuantitativos con referencia geográfica, a nivel nacional y a escala comunal, buscando identificar un área suprarregional donde la pérdida de población en zonas rurales se evidencie con mayor claridad. Posteriormente, se desarrolla un método de construcción de perfiles de comunas con despoblamiento rural, tomando como referencia datos del Sistema de Indicadores de Calidad de Vida Rural SICVIR y datos censales del período 2002-2017.
Desestatização dos serviços de saneamento no estado do Rio de Janeiro: avaliação dos primeiros meses de operação das novas concessionárias ou “estamos com saudades da Cedae”
Authors: Quintslr Suyá , Arouca Maria Clara Gonçalves
Published: October 2024

Resumo A universalização dos serviços de água e esgotamento sanitário no Rio de Janeiro ainda é uma questão não resolvida. A aposta do governo do estado para ampliar a cobertura foi a concessão dos serviços que estavam sob responsabilidade da Cedae à iniciativa privada em 2021. Poucos meses depois, entretanto, o descontentamento da população fluminense com as novas empresas se tornou incontestável, a julgar pelo número de reclamações nos diversos órgãos de defesa do consumidor e na justiça. Este artigo tem como objetivo compreender as consequências imediatas da mudança na gestão do saneamento a partir da perspectiva dos usuários. Para responder essa questão, recorreu-se à análise documental (editais de concessão, contratos e transcrição de Audiência Pública) e à análise de dados do serviço Consumidor.gov.br, gerido pelo Ministério da Justiça. Dentre os resultados, destacamos a insatisfação dos moradores das áreas de concessão com o aumento das contas de água e com a qualidade dos serviços prestados, aumentando a insegurança hídrica no nível dos domicílios. Ademais, a fragmentação da gestão, resultante da atuação de três novas empresas e da Cedae como produtora de água na RMRJ, bem como a multiplicação de instrumentos e contratos, vem dificultando o atendimento das demandas dos usuários.

Published: October 2024

ABSTRACT Introduction: Patients with Class II, division 1 malocclusion generally seek treatment to improve facial esthetics. Therefore, the orthodontist needs to know the changes in the soft profile produced by functional appliances. Objective: This study evaluated the soft tissue profile changes in patients treated during the peak of the pubertal growth spurt. Methods: Thirty selected patients were randomized into three treatment groups: Twin Block (TB), Herbst with dental anchorage (HDA), and Herbst with skeletal anchorage (HSA). All patients had computed tomographic images: pretreatment (T1) and after 12 months of active treatment (T2). Twenty-four soft tissue cephalometric measures were analyzed. The normality of all data was assessed by the Shapiro-Wilk test. Intragroup comparisons were analyzed using the t-paired test; the inter-group comparisons were determined through ANOVA and the post-hoc Tukey test. Results: At T1, no significant differences were observed between groups. At T2, in the intragroup comparison, facial soft tissue changes were statistically significant in the three groups for the lower lip, sulcus inferioris, facial soft tissue convexity in HDA group and TB group, and H angle in HDA group and HSA group, and soft tissue pogonium in TB group. In the inter-group comparison, no statistically significant differences were observed. Conclusion: It can be concluded that there were significant changes in soft tissue measurements that benefited Class II, division 1 patient’s facial profile treated with the functional appliances Twin Block, Herbst, and Herbst with skeletal anchorage. Nevertheless, no significant differences were detected among the effects obtained by the three treatment protocols.

Published: October 2024

ABSTRACT Introduction: Alveolar bone coverage can be diagnosed through cone beam computed tomography (CBCT) and this information can prevent orthodontic tooth movement beyond the biological limit. Objective: This study evaluated the impact of the bone coverage (BC) diagnosis by CBCT in the orthodontists’ planning. Methods: One hundred fifty-nine Brazilian orthodontists suggested treatment plans for six patients at two different times, using two sequential questionnaires. The first questionnaire consisted of extra and intra-oral photographs, one panoramic radiograph; one lateral cephalometric radiograph with Steiner and Tweed analysis, and the patient chief complaint. The second questionnaire included the same presentations of cases with tomographic images and the radiologist’s report. The McNemar test assessed the difference between the first and the second treatment plans. Results: In all six cases, most participants changed the treatment plan after evaluating the CBCT images and the radiologist’s report (93.7% in case 5, 78.6% in case 4, 74.2% in case 3, 69.8% in case 6, 66% in case 2 and 61% in case 1; p≤0.01). Conclusion: The evaluation of bone coverage through CBCT images has a substantial impact on the orthodontic diagnosis and planning of the Brazilian orthodontists.

ABSTRACT Introduction: The use of arch models is essential in diagnosis and planning in orthodontics. The demand for digital and printed models has increased among professionals. Objective: The aim of the study was to assess the agreement of horizontal and vertical linear measurements obtained from digital models, printed models, and direct measurements. Materials and Methods: Intraoral scans of 30 individuals were obtained. Digital measurements were performed using the STL files. From printed models, the measurements were done using a digital caliper, and the real measurements were done directly to the mouth of respective patients. Results: The one-sample t test showed no discrepancy between the paired sets of measurements, with the value of 0 (p>0.05). The evaluation of the measurements was done using Bland-Altman analysis in pairs. The three methods showed agreement in horizontal and vertical measurements. Linear regression analyses showed no proportional bias in the data (p>0.05). Conclusion: The horizontal and vertical measurements evaluated showed agreement when measured on digital models, printed models and directly in the individuals’ mouths.
Linguistic evidence and Tupi-Guarani/Cariban contacts in the Eastern Guianas: Wajãpi kasi ‘be strong’, pipi ‘father’s sister’ and kasuru ‘pearl’
Authors: Carvalho Fernando O. de
Published: October 2024

Abstract This brief paper proposes a Cariban etymology for the Wajãpi (Tupi-Guarani) verb -kasi ‘be strong’, which has been incorrectly suggested as being of Tupi-Guarani provenance. It is proposed that the source language for this diffusion event was Apalai, and not Wayana, as is usually claimed when the issue of the Cariban influx into Wajãpi is addressed. Two other Cariban loans are discussed, pipi ‘father’s sister’ and kasuru ‘pearl’, and in these cases as well, it is shown that diffusion from Apalai, not Wayana, is the more likely scenario. Implications of the findings are discussed.

ABSTRACT Purpose To investigate and correlate the lingual pressure of the anterior and posterior region in isometric contraction and during saliva swallowing of individuals with Osteogenesis Imperfecta (OI). Methods This was an observational cross-sectional study, 22 subjects participated, with an average age of 12.09 years, divided into mild OI (OIL) (type 1) (n=15) and moderate/severe OI (OIMG) (types 3, 4 and 5) (n=7). The Iowa Oral Pressure Instrument (IOPI) was used and tongue isometry pressure was measured in the anterior region, posterior region and during swallowing. Statistical analyses was done with the SPSS program using the Mann Whitney test, Spearman correlation and simple linear regression model. The significance level of p<0.05 was used. Results Pressure in tongue isometry was greater in the anterior region than in the posterior region in the total sample and in the OIMG group. The pressure of the anterior region during saliva swallowing was higher in the OIL group. Greater tongue pressure was also observed in the posterior region in the OIL group. Conclusion Greater pressure in the anterior region of the tongue is correlated with greater pressure in the posterior region of the tongue, but there is no significant correlation between the isometric tongue capacity and the tongue pressure during the saliva swallowing function.

Published: October 2024

Abstract Sucrose pulsing solutions are employed for hydrating and maintaining the turgor of flower stems by influencing respiratory processes, supplementing natural sugars, and reducing transpiration. Additionally, sucrose pulsing can impact the physiology of flower stems, altering metabolism, postharvest quality, and durability. However, these effects are unknown for many tropical species. The objective was to elucidate the physiological and biochemical effects of pulsing torch ginger inflorescences with varying sucrose concentrations postharvest. To achieve this, floral stems of torch ginger were collected and immersed in sucrose solutions with concentrations of 15%, 20%, and 25% for 24 hours. Following this period, the stems were transferred to water, and every 3 days, assessments were made for visual quality, the percentage of true flowers, absorption rate, water content, fresh and dry mass, and colorimetric parameters. The activation of the antioxidant system and measurement of macromolecule content were also conducted. Pulsing with 20% and 25% sucrose accelerated the emergence of true flowers, in addition to increasing the absorption rate and fresh mass values of the stems. At these concentrations, an increase in lipid peroxidation was also observed. No SOD or CAT expression was noted, but pulsing led to increased reserves of proteins and sugars. Pulsing with 15% sucrose is recommended for torch ginger to maintain higher visual quality up to the 9th day after harvest.

Published: October 2024

Abstract Mycorrhizae, exclusively associated with orchids, play a crucial role in plant growth, competitive interactions and pathogen protection. This study aimed to quantitatively assess the arbuscular mycorrhizal fungi (AMF) colonization rate in Dactylorhiza hatagirea at three sites in Kashmir Himalaya: Gulmarg, Sonamarg, and Pahalgam. Additionally, it examines soil parameters such as temperature, precipitation, pH, organic carbon, phosphorus, potassium and nitrogen. The root tips were collected at a depth of 0-20 cm. Samples were stored in sterilized polythene bags, refrigerated at 4±1 °C. Our results showed a significant variation in mycorrhizal colonization across three sites, with Pahalgam showing the highest at 78%, followed by Gulmarg at 73%, and Sonamarg at 57%. Principal Component Analysis (PCA) revealed 69.5% of the variation in environmental and soil variables. Positive correlations were observed among pH, nitrogen, potassium, and organic carbon, whereas phosphorus was negatively correlated with potassium and nitrogen. Gulmarg and Pahalgam were similar in soil characteristics, while Sonamarg exhibited distinct differences. Phosphorus positively correlated with Sonamarg but negatively with Pahalgam and Gulmarg, while other soil parameters showed opposite trends. The study emphasizes the significance of AMF colonization in understanding and enhancing plant-microbe interactions in terrestrial ecosystems, highlighting its role in nutrient cycling and the assimilation of essential elements like phosphorus and nitrogen.

Abstract Among the various technologies that can be used to modify the environmental conditions in protected cultivation, the use of agricultural waste and the use of cultivation benches of different colors can be beneficial to plants, providing adequate plant development and giving greater sustainability to the production system. The study aimed to identify the potential for using substrate based on agro-industrial waste and colored benches as alternatives for the production of Zinnia elegans. The experiment was conducted in the experimental area of the Mato Grosso do Sul State University (UEMS), in the Unit of Cassilândia, using a completely randomized design arranged in a 3 x 5 factorial scheme (three bench colors x five substrate doses), with three replications of four plants for each treatment. The treatments consisted of three colored benches (white, red, and control - metal bench) and five substrate mixtures with different concentrations of agro-industrial waste (SBRA) and Ecosolo® (0, 25%, 50%, 75%, and 100%) in which Zinnia elegans was grown. The variables analyzed were plant height, length of internodes, the number of leaves, relative chlorophyll content (SPAD), stem diameter, flower diameter, number of petals, time required for flowering and shoot dry mass. It was found that the composition of the substrate affected most of the characteristics evaluated, except for internode length and stem diameter. The benches resulted in significant differences in relative chlorophyll content and number of petals. Adding increasing proportions of SBRA, provides greater vegetative growth and flower development in Zinnia elegans plants.

Published: October 2024

Abstract Abiotic stresses, such as salinity, interfere with the growth and development of plants and can reduce, delay, or even inhibit the germination of the seeds. The knowledge about ornamental plants tolerance to those factors and the search for alternatives that reduce those effects, as is the use of salicylic acid, indicate paths to better development of the plants in environments affected by those stresses. This work aimed to evaluate the germination of Caroba-tree seeds and Brazilian peppertree seeds in different saline concentrations of sodium chloride (NaCl), using salicylic acid, as a possible saline stress attenuator. The experimental design utilized was completely randomized, with treatments arranged in factorial scheme 4 x 2 being four saline concentrations (0, 30, 60, and 90 mM of NaCl) combined with the absence (immersion in distilled water) or presence of salicylic acid (immersion in a solution containing salicylic acid at 1.0 mM). It was concluded that Caroba-tree showed moderate tolerance to salinity promoted by NaCl during seed germination. The average germination percentage was 83.91%. However, the seeds germinated at slower paces with the increasing saline solutions. The application of salicylic acid at the concentration of 1.0 mM did not influence the germination percentage of seeds subjected to saline solutions, regardless of the concentration. However, the seeds germinated faster in the absence of salicylic acid. Brazilian peppertree was not tolerant to salinity promoted by NaCl, with an average germination percentage of 47% and 40%, respectively, for the absence and presence of salicylic acid.

Published: October 2024

Abstract The rose is the most important ornamental and floral crop, as well as a valuable aromatic and medicinal plant. For accelerated production of planting material, clonal micropropagation is used. There are problems in obtaining an aseptic culture and the peculiarities of plant cultivation at different stages, depending on the variety. It is necessary to develop and optimize the technological cycle of cultivation in in vitro culture. The results showed that the highest viability of rose explants obtained from lateral buds was noted by sterilization with 0.2% silver nitrate solution of and 5% Lysoformin 3000 with an exposure of 15 minutes (82%-95%); the highest viability of explants obtained from etiolated shoots was observed when sterilized with 0.2% silver nitrate solution with an exposure of 10 minutes and 5% Lysoformin 3000 with an exposure of 15 min (82%-100%). The maximum length of the micro-shoots was noted in the ‘Dream Come True’ variety on a QL (Quoirin and Lepoivre) nutrient medium (on average 21.2 cm), in the ‘Full Sail’ variety - on a ½ QL medium (on average 24.9 cm). An increase in the concentration of 6-BAP from 0.5 to 1.0 mg L-1 in the nutrient medium contributed to an increase in the number of micro-shoots (by 1.7-1.9 times). The maximum root length was noted on the nutrient medium ½ QL (on average 88.7-95.3 cm). An increase in the concentration of IAA from 0.5 to 1.0 mg L-1 in the nutrient medium contributed to an increase in root length by 1.4-1.8 times. The protocol developed in this study allows to propagate these two varieties in vitro and produce a large number of plants.

Abstract Sealing systems that provide greater permeability to gasses can favor plant development in vitro. This study aimed to evaluate the effectiveness of a low-cost sealing system that allows different CO2-exchange rates [CO2-ER] to promote the in vitro growth of mother-of-millions (Kalanchoe delagoensis). Nodal segments of K. delagoensis were surface sterilized with sodium hypochlorite (2.5% active chlorine) and inoculated in culture vessels with Murashige and Skoog (MS) medium, sealed with rigid polypropylene lids with one (code: 1M; CO2-ER 21 μL L−1s−1) or two (code: 2M; CO2-ER 25 μL L−1s−1) gas-permeable membranes. In the control, the culture vessels were sealed with rigid polypropylene lids without membrane (code: 0M; CO2-ER 14 μL L−1s−1). After 45 days of culture, growth parameters were measured. Plants kept in culture vessels with 0M and 1M lids had a significant increase in the total plant length, main root, aerial part, and number of nodes when compared to the 2M sealing system. The number of leaves and plantlets along the leaf margin was 35.52% and 43.69% higher in plants grown in culture vessels with a 1M sealing system. In conclusion, sealing systems that allow gas exchange rates of up to 21 μL L−1s−1 (0M and 1M) provided the greatest in vitro development of mother-of-millions.

Published: October 2024

Abstract Clitoria ternatea L. is valued for its ornamental characteristics, medicinal properties, and culinary uses. However, efficient production of this species is constrained by seed coat dormancy, which impedes germination and seedling production. This study aimed to explore the physicochemical and morphological aspects of C. ternatea seeds, focusing on overcoming dormancy by applying multi-walled carbon nanotubes (MWCNTs) functionalized with carboxylic acid. The seeds were characterized by their physical, chemical, and mineral composition. Characterization included color dominance, geometry, thousand seed weight, and moisture content analyses. The seeds were treated with different concentrations (0, 100, 200, 400, 800 mg L-1) of multi-walled carbon nanotubes (MWCNT) during 24 hours of soaking. Then the germination rates were evaluated and morphological analysis was performed using scanning electron microscopy. Regarding the morphometry of the seeds, they were characterized by an oblong shape, a predominance of black tegument coloration, high levels of proteins, carbohydrates, lipids, fibers, and the presence of minerals such as potassium, magnesium, iron, and calcium. Seeds soaked in MWCNTs at a concentration of 200 mg L-1 exhibited an increase in germination percentage and the formation of normal seedlings compared to the control group (seeds soaked in water). The results suggest that MWCNTs can help to overcome seed dormancy and improve the quality of the resulting seedlings. Image analysis and scanning electron microscopy were crucial in understanding the physicochemical characteristics of the seeds and their changes upon exposure to MWCNTs.

Abstract Alstroemeria faces a stressful condition during its postharvest phase, as the leaves tend to yellow before the senescence of the flowers. Therefore, this study aimed to evaluate and compare the efficacy of different solutions previously recommended for the postharvest conservation of Alstroemeria hybrida L. cv. Akemi. The preservatives solutions tested included Florissant 210® with chlorine, 1-methylcyclopropene, benzyladenine, cycloheximide, silver thiosulfate, salicylic acid, spermine, silver nanoparticles, calcium chloride, gibberellin, Florissant 210®, Crystal, along with two control treatments using tap water and artesian well water. The results indicated significant differences when comparing the different water sources used in preparing the solutions. An increase in microbial population was observed over time postharvest, with genera Pseudomonas spp. and Bacillus identified. When tap water was utilized, the most suitable solutions included the addition of benzyladenine, gibberellin, Florissant 210®, Crystal, and Florissant 210® with chlorine. These results inform producers about selecting preservatives and water sources to enhance postharvest longevity and quality.

Published: October 2024

Abstract The application of plant growth regulators, primarily gibberellin inhibitors, is the main approach used for controlling the growth of ornamental plants. However, there is a growing interest in alternative products due to the risk of environmental toxicity associated with traditional methods. Methyl jasmonate (MeJa) is a natural substance found in plants and is considered to have low toxicity when used appropriately. Its use as a growth regulator has shown promise for controlling plant growth, but its effects have not been extensively explored in ornamental growth restriction. This study investigated the effects of foliar application of different concentrations of MeJa (0, 50, 100, and 150 µM) on the growth and leaf anatomy of Begonia ‘Dragon Wing’ Pink and Red. Plant growth parameters were evaluated, and qualitative-quantitative histological analyses of Begonia leaves were conducted. MeJa was efficient in compacting the plants, reducing height in 17.57% and diameter in 8.98% without compromising biomass, root growth, and flowering aspects. The average concentration studied also caused changes in leaf anatomy, increasing the thickness of the abaxial epidermis, reducing mesophyll thickness, the number of calcium oxalate crystals, and the size and number of stomata. The results demonstrated the promising effect of MeJa on controlling the growth of potted ornamental plants.

Abstract The use of native species in landscaping has gained prominence due to their adaptability and sustainability compared to exotic species. To introduce a new plant into landscaping, it is necessary to define desirable ornamental characteristics. This study aimed to evaluate the ornamental potential and the feasibility of reintroducing the brazilian native orchid Brassavola tuberculata Hook. in natural environments, aiming for its use in sustainable landscaping with and without fertilization. The research was conducted in two main stages. In the first stage, the morphological characteristics of three individuals with floral buds were analyzed, focusing on quantitative aspects. The results showed that the species presents elegant inflorescences and fragrant flowers, with slightly yellowish white petals and a labellum articulated at the base. In the second stage, 20 plants originating from asymbiotic seeding, approximately 10 cm in height, were reintroduced into phorophytes of Hymenaea courbaril. A mixture of buriti palm fiber and coconut chips was used as the substrate. The plants were divided into two groups: one received 12 g of controlled-release fertilizer (NPK 15-15-15 + micronutrients) and the other received no fertilization. Evaluations were carried out on the day of reintroduction (day zero) and at 7, 14, 21, 30, 60, 90, 120, 180, and 360 days after reintroduction. The results indicate that the morphological aspects of B. tuberculata attribute ornamental potential to the species, and it can be successfully reintroduced into natural environments, even without fertilization. The plant demonstrated a remarkable ability to adapt and survive, reorganizing its metabolism to cope with initial stress.

Abstract Sectoral and Thematic Chambers are forums for dialogue created by the Ministry of Agriculture and Livestock (MAPA), through which greater interaction with productive chains is sought, as well as the identification of opportunities and the definition of priority actions for developing Brazilian agriculture. The Thematic Chambers can contribute to the development of agriculture by identifying demands from the productive sector and linking them to proposals for research, development, and innovation by creating innovation agendas. For that, the analysis of productive chains and their practices allows a better understanding of agribusiness, which consequently enables the development of effective strategies to promote the growth and development of a sector. The objective of the agenda in Flower, Turfgrass, and Ornamental Plant is to present an analysis of the main problems and opportunities for innovation in the productive chains. A diagnosis of the current situation focusing on a vision for the future was required to prepare this Innovation Agenda. The methodological approach was divided and conducted through different analyses: a) Analysis of the evolution of the Flower and Ornamental Plant Market; b) Analysis of contributions, impact, and expectations of the links in the production chain; c) Mapping of human capital in Brazilian science with the potential to contribute to technological innovations for the market of flowers, grasses, and ornamental plants. The Innovation Agenda prioritizes the most relevant obstacles, establishes their level of importance, and identifies ten significant Innovation Challenges to be addressed by the public and private sectors of the country. Through the agenda, strategic actions are suggested for research, technology transfer, and public policies, which are essential for the technological development of the sector, without neglecting its socioeconomic and environmental sustainability. For each Innovation Challenge, Strategic Actions were suggested to be pursued, and Brazil has the technical competence distributed across the country, in nationally recognized universities and research institutes and enterprises.
The construction of the Dynamic Occupational Therapy Method: a non-dichotomous production between knowledge and practice

Published: October 2024

Abstract Introduction Occupational Therapy arrived in Brazil under the logic of rehabilitation and distanced from the Brazilian reality. Therefore, occupational therapists embarked on the adventure of thinking about the profession and its theoretical-practical aspects based on their contexts. Jô Benetton is among these professionals. Formed in 1970, she began a research project that culminated in the construction of the Method Dynamic Occupational Therapy - DOTM. Recent literature reviews that focus on the theme of epistemological constructions, when using journal indexing mechanisms, only cite the author's work, without explaining her contributions to the field and her knowledge construction process. Objective To elucidate aspects of the DOTM construction process, to understand how the production of knowledge occurred based on practical situations placed as an object of study, which resulted in the proposition of a theoretical-methodological framework specific to and in Brazilian Occupational Therapy. Method Qualitative research, with data from two interviews with Jô Benetton and one with Sonia Ferrari, analyzed thematically. Results Three main themes were identified that express how the DOTM was constructed in the light of a pragmatist epistemology: 1) Concerns, searches and experiments; 2) Inventions; 3) Emergence of a way of thinking-doing in practice. Conclusion The construction of the DOTM occurred in a non-dichotomous way between the production of knowledge and care, allowing the establishment of new relationships between theory and practice.
Prisões em flagrante por crimes de drogas: análise da questão racial em duas metrópoles brasileiras

Resumo Este artigo discute a atuação das organizações policiais nos chamados “crimes de drogas”. A partir de análise de dados sobre prisões em flagrante nas cidades de São Paulo (SP) e Belo Horizonte (MG), buscou-se mensurar o quanto dimensões socioespaciais (território onde ocorreram as prisões, bem como sexo, idade e raça/cor das pessoas presas) afetam a decisão policial de classificar os casos como “porte de drogas para uso pessoal” ou “tráfico de drogas”. Por serem o que a legislação define como “crimes sem vítimas”, as “ocorrências de drogas” evidenciam processos de suspeição racializada e territorializada que orientam o policiamento ostensivo no Brasil. Em São Paulo, parece haver uma diretriz institucional para que quase todos os casos sejam classificados como “tráfico”. Já em Belo Horizonte, prisões feitas em favelas possuem chances desproporcionalmente mais altas de receber a tipificação mais gravosa. Em ambas as capitais, o perfil racial das pessoas presas influencia a tipificação criminal.
Potencialidade de painéis sanduíche com núcleo de bioconcreto leve com resíduo do endocarpo de palma para uso na construção civil

Resumo O uso de painéis sanduíche na construção civil é uma alternativa viável na busca por materiais com baixo peso próprio, menor condutividade térmica e resistentes à compressão. Para aumentar a sustentabilidade dessa solução, é preciso substituir o reforço de aço das faces e o núcleo em EPS por materiais que apresentem menor custo energético e redução da emissão de gases do efeito estufa durante a produção. Nesse contexto, o presente trabalho tem como objetivo, desenvolver um painel sanduíche com núcleo de concreto leve feito com endocarpo do dendê em substituição do agregado graúdo convencional e faces com argamassa reforçada com fibras curtas de sisal. O bioconcreto foi produzido com dois teores de endocarpo do dendê (100% e 150% da massa de aglomerante) e duas relações água/aglomerante, de 0,35 e 0,45. O aumento do teor de endocarpo resulta em aumento da absorção de água e redução da resistência mecânica, mas os painéis apresentaram massa específica menor que 1480 kg/m³ e resistência a compressão maior que 7 MPa o que os qualifica para uso como alvenaria de vedação. O uso de fibras vegetais permitiu o aumento da tenacidade sob flexão mesmo após o início da fissuração do painel.

Abstract Mortars’ workability results from other properties, such as consistency, plasticity, cohesion, water retention, exudation, initial adhesion and density. A workable mortar distributes itself in application, doesn’t segregate during transport, and remains plastic during the application time. This property depends on several application factors, together with the constituent materials. Therefore, this study aims to assess the influence of the formulation, aggregate type and water content on rheological behavior of rendering mortars, combined with particle packing studies. For this purpose, three usual mortar formulations were chosen. The minimum water content was calculated through the concepts of particle packing and the squeeze flow test. As a result, the influence of each constituent on the workability of the mortar was determined, together with the formulations optimized by the aggregate type. The water content analysis revealed the wet packing density and minimum value required for the formation of the water film around the particles.

Abstract Thermal resilience refers to a building’s capacity to adapt to extreme thermal variations, maintaining a healthy environment for its occupants. This study aims to assess the thermal resilience of a naturally ventilated low-income residential building in overheating conditions within a region of savannah tropical climate. Various indices, including adaptive thermal comfort, Indoor Overheating Degree (IOD) and Exceedance Hours (HE), Heat Index (HI), and Standard Effective Temperature (SET) were calculated in current and climate change scenarios using two models, a standard building (HISp) and a building that incorporates passive bioclimatic strategies (HISe).It was demonstrated that thermal insulation and low absorption strategies significantly contribute to indoor environmental quality, reducing the risk of overheating exposure in all evaluated scenarios. Despite reducing discomfort hours and critical thermal stress levels, the idealized strategies do not provide adequate habitability conditions for the occupants. Overheating will become even more severe in projected future scenarios. Among the two dwellings, HISe demonstrates a superior potential to mitigate the risk of overheating compared to HISp in all the scenarios evaluated.

Abstract Long-life packaging is being used informally as an alternative to improve thermal insulation in single-family wooden houses. Its usage is backed by environmental concerns to reuse these solid residues as a radiant barrier for heat transmission. However, some published studies have only analyzed its thermal insulation efficiency, without considering the material performance in fire situations. Given this scenario, the objective of this research is to present the analysis and classification to a fire reaction of long-life packaging. In addition to the non-combustibility test, ignitability, radiant wall panel, optical smoke density and single burn item (SBI) tests were carried out. The results showed that the material is combustible and is classified as fire reaction class VI, according to the criteria for special materials. Thus, on the findings of this study, it can be concluded that long-life packaging should not be used as a lining for the internal surfaces of buildings.
