Abstract Alkali-activated materials are known by its fast development of high mechanical strength and high chemical stability, and the possibility to reuse waste in its formulation contributes to the reduction of several environmental impacts. The present developed an alkali-activated mortar based on palm oil fuel ash and wood ash. To this end, the physical and chemical characteristics of the materials were evaluated through tests of laser diffraction, x-ray diffraction and fluorescence, and thermogravimetry, followed by the formulation of binders by varying the CaO/SiO 2 and SiO 2 /Al 2 O 3 molar ratios. Six formulations were tested and metakaolin was used in two of them as a complementary source of Al 2 O 3 . After evaluating the mechanical properties of the binders, three mortars were formulated with a 25% and 50% variation in the volumetric aggregate content. Total strength development was observed in just 2 days, achieving an average flexural strength of 3.54 MPa and compressive strength of 10.5 MPa. The mortars showed low susceptibility to the development of efflorescence and an absorption rate of 9.6%, confirming the reuse potential of the ashes as precursors for the development of mortars.

Resumo Os materiais álcali-ativados são conhecidos por apresentarem rápido desenvolvimento de elevada resistência mecânica, alta estabilidade química e possível reutilização de resíduos durante sua formulação, o que permite reaproveitar recursos e reduzir impactos ambientais. O presente trabalho desenvolveu argamassas álcali-ativadas empregando cinzas de caldeira de dendê e de queima de madeira, beneficiadas por meio de moagem e peneiramento. Avaliaram-se as características físico-químicas dos materiais por meio de ensaios de difração de raios laser, difração e fluorescência de raios x e termogravimetria, e formularam-se aglomerantes variando as relações molares CaO/SiO2e SiO2/Al2O3. Foram avaliadas seis formulações, duas das quais commetacaulim como fonte complementar de Al2O3. Avaliadas as propriedades mecânicas dos aglomerantes, formularam-see avaliaram-se três argamassas com variação do teor volumétrico de agregado em 25% e 50% quanto a trabalhabilidade, resistência mecânica, absorção de água e desenvolvimento de eflorescência. Houve desenvolvimento total de resistência com apenas 2 dias, e resistência à tração média de 3,54 MPa e à compressão de 10,5 MPa. As argamassas apresentaram baixa susceptibilidade ao desenvolvimento de eflorescência e taxa de absorção de 9,6%, o que confirma o potencial de aproveitamento dessas cinzas como material precursor para argamassas.

Abstract Background Contrast-induced nephropathy (CIN) is defined as worsening renal function, represented by an increase in serum creatinine of ≥ 25% or ≥ 0.5 mg/dL up to 72 h after exposure to iodinated contrast medium (ICM). The most effective preventive measure to date is intravenous hydration (IVH). Little is known about the effectiveness of outpatient oral hydration (OH). Objetive To investigate whether outpatient OH with water is as effective as IVH with 0.9% saline solution in preventing CIN in elective coronary procedures. Methods In this retrospective observational study, we analyzed the medical records and laboratory data of individuals undergoing percutaneous coronary procedures with ICM. Data collected between 2012 and 2015 refer to individuals who underwent IVH and those collected between 2016 and 2020 (after implementation of an OH protocol) correspond to individuals who underwent OH at home before and after coronary procedures as instructed by the nursing team. Statistical significance was established at α = 0.05. Results In total, 116 patients were included in this study: 58 in the IVH group and 58 in the OH group. An incidence of CIN of 15% (9/58) was observed in the group that received IVH and an incidence of 12% (7/58) was seen in the group that received OH (p = 0.68). Conclusion The OH protocol, performed by the patient, appears to be as effective as the in-hospital IVH protocol for the renal protection of individuals susceptible to CIN in elective coronary interventions. These findings should be put to test in larger trials.

Resumo Fundamento A nefropatia induzida por contraste (NIC) é definida como deterioração da função renal, representada por um aumento da creatinina sérica ≥25% ou ≥0,5 mg/dL até 72 horas após a exposição ao meio de contraste iodado (MCI). A medida preventiva mais eficaz até o momento é a hidratação venosa (HV). Pouco se sabe sobre a eficácia da hidratação oral (HO) ambulatorial. Objetivo Investigar se a HO ambulatorial com água é tão eficaz quanto a HV com solução salina a 0,9% na prevenção de NIC em procedimentos coronarianos eletivos. Métodos Neste estudo observacional retrospectivo, foram analisados prontuários médicos e dados laboratoriais para coletar dados de indivíduos submetidos a procedimentos coronarianos percutâneos com MCI. Os dados coletados entre 2012 e 2015 avaliaram indivíduos que foram submetidos à HV e entre 2016 e 2020 (após a implementação de um protocolo de HO), os indivíduos que foram submetidos à HO em casa antes e depois de procedimentos coronarianos, conforme orientação da equipe de enfermagem. A significância estatística adotada foi de α=0,05. Resultados No total, 116 pacientes foram incluídos neste estudo, 58 no grupo HV e 58 no grupo HO. Observou-se incidência de NIC de 15% (9/58) no grupo que recebeu HV e 12% (7/58) no grupo que recebeu HO (p=0,68). Conclusão O protocolo de HO realizado pelo paciente parece ser tão eficaz quanto o protocolo de HV hospitalar na proteção renal de indivíduos suscetíveis a desenvolver NIC em intervenções coronarianas eletivas. Essas descobertas devem ser testadas em ensaios mais abrangentes.

Resumo Após reestruturação do sistema penitenciário e implementação do programa “Estado Presente”, focado na redução de mortes intencionais, o Espírito Santo observou redução de 10,2% no número de homicídios, entre 2010 e 2014. Avaliamos causalidade e benefíciocusto dessas políticas. Utilizamos controle sintético ao estimar impacto sobre o número de homicídio e, comparamos o valor estatístico das vidas poupadas ao valor presente dos dispêndios financeiros associados à implementação das políticas. Os resultados encontrados sugerem que na ausência das políticas, o número de homicídio ao invés de diminuir aumentaria 28,8%. Cada real investido trouxe ganho de bem-estar social equivalente a R$2,36. JEL Codes O10, K42, C40

Abstract Objective To perform a systematic review and meta-analysis of studies on maternal, fetal, and neonatal outcomes of women with singleton pregnancies, after spontaneous conception, and with the diagnosis of amniotic sludge before 37 weeks of gestational age. Data Sources We conducted a search on the PubMed, Cochrane, Bireme, and Theses databases until June 2022. Selection of Studies Using the keywords intra-amniotic sludge or fluid sludge or echogenic particles, we found 263 articles, 132 of which were duplicates, and 70 were discarded because they did not meet the inclusion criteria. Data Collection The articles retrieved were analyzed by 2 reviewers; 61 were selected for full-text analysis, 18 were included for a qualitative analysis, and 14, for a quantitative analysis. Data Synthesis Among the maternal outcomes analyzed, there was an increased risk of preterm labor (95% confidence interval [95%CI]: 1.45–2.03), premature rupture of ovular membranes (95%CI: 1.99–3.79), and clinical (95%CI: 1.41–6.19) and histological chorioamnionitis (95%CI: 1.75–3.12). Regarding the fetal outcomes, there was a significant increase in the risk of morbidity (95%CI: 1.80–3.17), mortality (95%CI: 1.14–18.57), admission to the Neonatal Intensive Care Unit (NICU; 95%CI: 1.17–1.95), and neonatal sepsis (95%CI: 2.29–7.55). Conclusion The results of the present study indicate that the presence of amniotic sludge is a risk marker for preterm delivery. Despite the heterogeneity of the studies analyzed, even in patients with other risk factors for prematurity, such as short cervix and previous preterm delivery, the presence of amniotic sludge increases the risk of premature labor. Moreover, antibiotic therapy seems to be a treatment for amniotic sludge, and it may prolong pregnancy.

Resumo Objetivo Realizar revisão sistemática e metanálise de estudos que avaliaram os desfechos maternos, fetais e neonatais em gestantes de gravidez única, após concepção espontânea, e com o diagnóstico de sludge amniótico antes de 37 semanas de idade gestacional. Fontes dos dados Realizou-se uma pesquisa nas bases de dados PubMed, Cochrane, Bireme e Teses até junho de 2022. Seleção dos estudos Usando as palavras-chave intra-amniotic sludge ou fluid sludge ou echogenic particles, foram encontrados 263 artigos, 132 dos quais eram duplicatas, e 70 foram descartados por não corresponderem aos critérios de inclusão. Coleta de dados Os artigos encontrados foram analisados por 2 revisores; 61 foram selecionados para análise de texto completo, 18 foram incluídos em uma análise qualitativa e 14, em uma análise quantitativa. Síntese dos dados Entre os desfechos maternos analisados, houve aumento do risco de trabalho de parto prematuro (intervalo de confiança de 95% [IC95%]: 1.45–2.03), rotura prematura de membranas ovulares (IC95%: 1.99–3.79), e corioamnionite clínica (IC95%: 1.41–6.19) e histológica (IC95%: 1.75–3.12). Em relação aos desfechos fetais, houve aumento significativo do risco de morbidade (IC95%: 1.80–3.17), mortalidade (IC95%: 1.14–18.57), admissão em Unidade de Tratamento Intensivo (UTI) neonatal (IC95%: 1.17–1.95) e sepse neonatal (IC95%: 2.29–7.55). Conclusão Os resultados do presente estudo indicam que a presença de sludge amniótico é um marcador de risco para parto prematuro. Apesar da heterogeneidade dos estudos analisados, até mesmo em pacientes com outros fatores de risco para prematuridade, como colo curto e trabalho de parto prematuro anterior, a presença de sludge amniótico aumenta o risco de trabalho de parto prematuro na gestação. Além do mais, a antibioticoterapia parece ser um tratamento para o sludge amniótico, e pode ser capaz de prolongar a gravidez.

Abstract: En | Text: En | PDF: En

Cancer treatment represents one of the main scientific study targets today, mainly due to the pronounced side effects arising from chemotherapy. This study reports the synthesis, characterization, and anticancer activity of ten compounds from the Morita-Baylis-Hillman reaction. Ethylene glycol diacrylate was used as a double Michael acceptor in reactions with isatin derivatives to give homodimers of 3-hydroxyindolin-2-one core, recognized in the literature for its extensive pharmacological profile. The use of 1,4-diazabicyclo[2,2,2]octane (DABCO) as a catalyst and room temperature were the optimal conditions for the study reaction. The isolated yields were up to 63%, with most reaction times inferior to 24 h, some as fast as 15 min. The anticancer potential of the synthesized dimers was evaluated in vitro against three cancer strains, resulting in average inhibitory concentrations up to 0.72 µM. It was also found that the best performing homodimers are more active than their monomeric counterparts. Considering the promising selectivity indices observed, the preliminary results obtained here act as a basis for broader tests regarding the effectiveness of homodimeric adducts against cancer cells.

Abstract It is repeatedly stressed the need to characterize the extant biodiversity in tropical ecosystems. However, inventory studies are still progressing slowly in dry ecosystems, leading to the underestimation of their true biodiversity and hindering conservation efforts. In this study, we present primary and secondary data, along with an updated list of amphibians and reptiles from two localities in the São Francisco-Gurguéia region in Piauí. Additionally, we compare the species composition between nine areas within the Caatinga, which were sampled using standardized methods over the past ten years, to examine broader spatial patterns of community composition. To survey reptiles and amphibians, we employed similar methods and sampling efforts in two areas within the Serra das Confusões National Park (SCNP) region. Our surveys recorded a total of 73 species of amphibians and reptiles, of which 24 are new distribution records for the SCNP region. Consequently, our findings increase the known herpetofauna in the region to 94 species. Despite their proximity, the two sites in the SCNP region exhibited only 42% similarity in species composition, and they differed significantly from other areas within the Caatinga. Furthermore, even the closer Caatinga areas presented differences in species composition, highlighting the necessity to evaluate biodiversity across the landscape and contribute to understanding biogeographic patterns.

Resumo É repetidamente enfatizada a necessidade de caracterizar a biodiversidade vivente em ecossistemas tropicais. No entanto, os estudos de inventário ainda estão progredindo lentamente em ecossistemas secos, levando à subestimação de sua verdadeira biodiversidade e dificultando os esforços de conservação. Neste estudo, apresentamos dados primários e secundários, juntamente com uma lista atualizada de anfíbios e répteis de duas localidades na região de São Francisco-Gurguéia, do Piauí. Além disso, comparamos a composição de espécies entre nove áreas dentro da Caatinga, que foram amostradas usando métodos padronizados nos últimos dez anos, para examinar padrões espaciais mais amplos de composição da comunidade. Para estudar répteis e anfíbios, utilizamos métodos e esforços de amostragem semelhantes em duas áreas na região do Parque Nacional da Serra das Confusões (PNSC). Nossos levantamentos registraram um total de 73 espécies de anfíbios e répteis, das quais 24 são novos registros de distribuição para a região do PNSC. Consequentemente, nossos resultados aumentam a herpetofauna conhecida na região para 94 espécies. Apesar da proximidade, os dois locais na região do PNSC exibiram apenas 42% de similaridade na composição de espécies e diferiram significativamente de outras áreas dentro da Caatinga. Mesmo áreas mais próximas da Caatinga apresentaram diferenças na composição de espécies, destacando a necessidade de avaliar a biodiversidade em toda a paisagem e contribuir para a compreensão de padrões biogeográficos.

Abstract The Parque Nacional Grande Sertão Veredas, northern Minas Gerais, is located in the Cerrado, a global hotspot, and the literature lacks information about its communities of social wasps, insects that perform numerous services for the functioning of ecosystems. Therefore, this study aimed to conduct an inventory of social wasps (Vespidae: Polistinae) in the Parque Nacional Grande Sertão Veredas, and compare its richness and composition with three other fully protected conservation units in northern Minas Gerais and Vale do Jequitinhonha, Minas Gerais. A total of 41 species of 14 genera of social wasps were recorded, including a new occurrence in the state: Mischocyttarus campestris Raw, 1985. The presence of distinct social wasp communities in the Cerrado and Caatinga conservation units analyzed in this study, reinforces and justifies the creation of these fully protected areas, which ensure the conservation of this biological heritage and the environmental services provided by these taxa, besides providing subsidies for the management and sustainable use of the natural resources of these conservation units.

Resumen O Parque Nacional Grande Sertão Veredas, norte de Minas Gerais, inserido no Cerrado, hotspot mundial, carece de informações sobre a comunidade de vespas sociais, insetos que desempenham inúmeros serviços para o funcionamento dos ecossistemas. Portanto, o objetivo deste estudo foi realizar um inventário de vespas sociais (Vespidae: Polistinae) no Parque Nacional Grande Sertão Veredas, além de comparar sua riqueza e composição com à de outras três Unidades de Conservação de proteção integral no Norte e no Vale do Jequitinhonha no estado de Minas Gerais. Foram registradas 41 espécies de 14 gêneros de vespas sociais, com um novo registro de ocorrência para o estado, Mischocyttarus campestris Raw, 1985. A presença de comunidades distintas de vespas sociais nas Unidades de Conservação no Cerrado e Caatinga, analisadas no presente estudo, reforça e justifica a criação dessas áreas de proteção integral, que assegura a conservação desse patrimônio biológico, bem como os serviços ambientais prestados por esses táxons, além de fornecer subsídios para o manejo e uso sustentável dos recursos naturais dessas Unidades de Conservação.

RESUMO O objetivo deste estudo foi analisar as concepções e princípios de prática de liderança de treinadores de alta performance do futebol brasileiro. Participaram do estudo, por meio de entrevistas semiestruturadas, cinco treinadores de futebol masculino que já atuaram na 1ª divisão brasileira, conquistando títulos estaduais e nacionais e com experiência em equipes e seleções estrangeiras. As principais evidências apontam para competências gerais, estratégias de gestão, conhecimento profissional, princípios e valores individuais. Conclui-se que os treinadores possuem conhecimento processual tácito instintivo que resulta numa filosofia de liderança desconexa e competências interpessoais mais evidentes. Sugere-se que os treinadores utilizem o modelo trifásico de eficácia de liderança e a prática da reflexão sistematiza de forma a potenciarem a sua eficácia de liderança. brasileiro semiestruturadas ª brasileira estrangeiras gerais gestão profissional individuais Concluise Conclui se evidentes Sugerese Sugere

ABSTRACT The aim of this study was to analyze the conceptions and leadership principles of high-performance coaches in Brazilian soccer. Participants were five male soccer coaches who have worked in the Brazilian first division, winning state and national titles, and having experience in international teams. Semi-structured interviews were performed. Main evidences show several competencies, management strategies, professional knowledge, principles, and personal values. We concluded that the coaches have tacit instinctive procedural knowledge that results in a disconnected leadership philosophy and interpersonal knowledge more evident. It is suggested that coaches use the three-phase leadership model and the practice of systematic reflection in order to enhance their leadership effectiveness. highperformance high performance division titles teams Semistructured Semi structured performed competencies strategies values evident threephase three phase effectiveness

ABSTRACT: Ozone is a colorless gas with a characteristic odor present in nature in the form of trivalent oxygen. In 2015, the Federal Council of Dentistry (CFO/Brazil) approved the use of ozone therapy and in 2018 the Ministry of Health (MS/Brazil) approved the application of Ozone Therapy as a Complementary Integrative Practice in the Unified Health System. Therefore, the objective of this study was to verify the applicability of ozone therapy in dental practice. This is an integrative literature review whose search was performed in the Medline/Pubmed, LILACS, SciElo, and Google Scholar databases. Studies published in the last 5 years in English, Portuguese or Spanish were eligible. After the search, 312 titles were found and after exclusion of duplicates and analysis of abstracts and full text, 13 articles were included in this review. The literature reports the application of ozone therapy in several areas in the treatment of acute and chronic diseases. As a mechanism of action, ozone has a direct antimicrobial effect, immunoregulation, antioxidant defenses, analgesic, and vasodilator effects. In dentistry, its applicability is mainly in preventive dentistry and as a complement in surgical procedur es, endodontic, and periodontal treatments.

RESUMEN: El ozono es un gas incoloro de olor característico presente en la naturaleza en forma de oxígeno trivalente. En 2015, el Consejo Federal de Odontología (CFO) aprobó el uso de la ozonoterapia y en 2018 el Ministerio de Salud aprobó la aplicación de la Ozonoterapia como Práctica Integrativa Complementaria en el Sistema Único de Salud. Por lo tanto, el objetivo de este estudio fue verificar la aplicabilidad de la ozonoterapia en la práctica odontológica. Esta es una revisión integrativa de la literatura cuya búsqueda se realizó en las bases de datos Medline/Pubmed, LILACS, SciElo y Google Scholar. Fueron elegibles los estudios publicados en los últimos 5 años en inglés, portugués o español. Después de la búsqueda, se encontraron 312 títulos y después de la exclusión de duplicados y análisis de resúmenes y texto completo, se incluyeron 13 artículos en esta revisión. La literatura reporta la aplicación de la ozonoterapia en varias áreas en el tratamiento de enfermedades agudas y crónicas. Como mecanismo de acción, el ozono tiene un efecto antimicrobiano directo, de inmunorregulación, defensas antioxidantes, efectos analgésicos y vasodilatadores. En odontología su aplicabilidad es principalmente en odontología preventiva y como complemento en procedimientos quirúrgicos, tratamientos endodónticos y periodontales.

Resumen La selva amazónica presenta diferentes estratos forestales, debido a su estructura heterogénea. En el que estos estratos pueden variar en altos, medios y bajos. El conocimiento de los diferentes patrones de estructuras verticales que se encuentran en el bosque es extremadamente importante para comprender la dinámica de la vegetación, lo que influye en las estrategias de conservación del bosque. Con el fin de optimizar el proceso de clasificación de los diferentes tipos de estratos, el objetivo del presente trabajo fue utilizar redes neuronales artificiales (RNA) para clasificar estos estratos. Se utilizaron dos algoritmos de resilient propagation (Rprop+ y Rprop-), en cuatro configuraciones diferentes de variables de entrada. El entrenamiento y la prueba de los ocho modelos de RNAs se realizaron utilizando el software R. Los modelos se evaluaron mediante una matriz de confusión. En qué modelos con entradas: HT, DAP y QF; HT, DAP y solo HT del algoritmo Rprop + obtuvieron 100% de aciertos en la clasificación de estrato, presentando una alta tasa de aprendizaje, confiabilidad y generalización de datos.

Abstract The Amazon forest presents different forest strata, due to its heterogeneous structure. In which these strata can vary in upper, middle and lower. Knowledge about the different patterns of vertical structures found in the forest is extremely important for understanding the vegetation dynamics, influencing forest conservation strategies. In order to optimize the process of classifying the different types of strata, the objective of the present work was to use artificial neural networks (ANNs) to classify these strata. Two resilient propagation algorithms (Rprop + and Rprop-) were used, in four different configurations of input variables. The training and testing of the eight RNA models were performed using the R software. The models were evaluated using a confusion matrix. In which models with inputs: HT, DAP and QF; HT, DAP and only HT from the Rprop + algorithm obtained 100% correct answers in the classification of strata. Demonstrating a high rate of learning, reliability and generalization of data.

SUMMARY OBJECTIVE: The primary objective was to analyze and report on the complications that occurred in the cochlear implant surgeries performed at a large philanthropic teaching hospital located in a low-income area of Brazil. METHODS: A historical cohort study that analyzed surgical records of 432 patients of all age groups and both genders who received unilateral cochlear implant in a tertiary referral center that serves only Brazil's Public Health Care System patients, from February 2009 to December 2017. RESULTS: A total of 67 (15.5%) complications occurred in the cochlear implant surgeries, with 21 (5.4%) major complications. Minor complications occurred in 50 (12%) cases. The most frequent major complication was receiver-stimulator displacement (four cases). There were three cases of hardware failure. Only one case of meningitis and one case of facial nerve paralysis (grade VI in House-Brackmann scale) were found. Six patients needed to be explanted due to a major complication. The relative risk of major complications in the population aged 60 years and older was 4.41 (1.53–12.72; 95% confidence interval [CI]). CONCLUSIONS: Elderly patients suffered more complications than younger patients. receiver-stimulator displacement and dizziness were the most frequent complications (major and minor, respectively). The overall complication rates were comparable to those in the literature. Age as an isolated risk factor for complications in cochlear implant surgery is a path to be explored in future observations.

Resumo O objetivo deste trabalho foi avaliar os danos causados por bovinos a clones de eucalipto em sistema silvipastoril, nove meses após o plantio. O experimento foi conduzido em arranjo espacial de faixas, o delineamento foi inteiramente casualizado com seis repetições e quatro tratamentos: a) Clone VM01 com acesso do gado aos nove meses (TR1); b) Clone I144 com acesso do gado aos nove meses (TR2); c) Clone VM01 sem acesso do gado (TR3); e d) Clone I144 sem acesso do gado (TR4). Foram introduzidos seis bovinos mestiços anelorados em cada tratamento, com peso de 300 kg no pasto de Brachiaria brizantha cv. Xaraés (MG-5) e mantido por três períodos de aproximadamente 14 dias. Os danos nas árvores foram avaliados aos 300, 332 e 360 dias após o plantio em função das partes danificadas (incidência) e uma escala de classes e notas foi estabelecida. A entrada de bovinos no sistema silvipastoril aos nove meses após o plantio afetou negativamente (P≤0,05) o crescimento inicial do povoamento florestal. Foram identificados danos de baixa intensidade, como quebra de galhos, alta intensidade, como quebra do tronco e de extrema intensidade, como tombamento, variando conforme o clone. Não se recomenda o acesso dos animais aos nove meses após o plantio florestal, devendo ser realizado em idades mais avançadas dos clones, tendo estes, maiores dimensões em altura total e diâmetro à altura do peito.

Abstract The objective of this work was to evaluate the damage caused by cattle to eucalyptus clones in silvopastoral system, after nine months after planting. The experiment was conducted in a spatial arrangement of tracks considering the design was completely randomized with six replications and four treatments: a) Clone VM01 with access to cattle at nine months (TR1); b) Clone I144 with access to cattle at nine months (TR2); c) VM01 clone without cattle access (TR3); and d) Clone I144 without cattle access (TR4). Six annealated crossbred cattle were introduced in each treatment, weighing 300 kg in Brachiaria brizantha cv. Xaraés (MG-5) and maintained for three periods of approximately 14 days. Tree damage was assessed at 300, 332 and 360 days after planting according to the damaged parts (incidence) and a scale of classes and grades was established. The entry of cattle in the silvopastoral system nine months after planting, negatively affected (P≤0.05) the initial growth of the forest stand. Low-intensity damage was identified as branch breaking, high intensity as trunk breaking and extreme intensity as tipping, varying according to the clone. Animal access is not recommended at nine months after forest planting and should be carried out at older ages of the clones, with larger dimensions in total height and diameter at breast height.

RESUMO O Brasil se destaca no cenário internacional em relação a produção de celulose de fibra curta. Apesar da grande biodiversidade brasileira, essa produção está baseada em clones de espécies exóticas de Eucalyptus. Nesse contexto, pode haver grande potencial na avaliação de novas fontes de fibras da flora brasileira, incluindo a região amazônica. O presente estudo teve como objetivo avaliar o potencial tecnológico da madeira de Ochroma pyramidale (Malvaceae) para produção de celulose kraft. Indivíduos de quatro anos de idade foram colhidos em um plantio comercial para produção de serrados no Estado do Mato Grosso. Determinamos as propriedades químicas (teores de holocelulose, lignina Klason, lignina solúvel, extrativos e cinzas), físicas (massa específica e porosidade) e morfologia de fibras (comprimento e largura de fibras, diâmetro do lume, espessura e fração de parede, coeficiente de flexibilidade, índice de enfeltramento e de Runkel) da madeira. Na polpação kraft a carga alcalina aplicada variou entre 10 e 24%, com intervalo de 2%. A madeira de Ochroma pyramidale apresentou características favoráveis à produção de polpa celulósica, como dimensões apropriadas das fibras e baixos teores de lignina, extrativos e cinzas. Os teores de álcali ativo residual e pH do licor negro apresentaram relação crescente com a carga alcalina aplicada nos processos de polpação. O acréscimo da carga alcalina reduziu o rendimento em polpação, número kappa, teor de rejeitos e aumentou o teor de ácidos hexenurônicos.

ABSTRACT Brazil stands out in the international scenario in the production of short-fiber pulp. Despite the great Brazilian biodiversity, that production is based on exotic Eucalyptus clones. In this sense, there may be great potential in the assessment of new sources of fibers from the Brazilian flora, including the Amazon. The present study aimed to assess the technical potential of the wood of Ochroma pyramidale (Malvaceae) for the production of kraft pulp. Four-year-old trees were harvested from a commercial forest for lumber production in Mato Grosso state (Brazil). We determined the wood’s chemical compositions (holocellulose, Klason lignin, soluble lignin, extractives and ash contents), physical properties (density and porosity), and fiber morphology (fiber length, width and thickness, lumen diameter, wall fraction, coefficient of flexibility, and slenderness and Runkel ratios). The wood was subjected to pulping with an effective alkali charge ranging from 10 to 24%, with intervals of 2%. Ochroma pyramidale wood presented characteristics favorable to the production of cellulosic pulp, such as appropriate fiber dimensions and low lignin, extractives, and ash content. The amount of residual active alkali and pH of the black liquor were positively related to the increase of the alkali charge employed in the pulping process. The increase of alkali charge decreased the pulp yield, kappa number and waste content, and increased the hexenuronic acid concentration.

ABSTRACT. Rock dusts in association with organic sources have been used in agriculture to improve soil chemical characteristics and food composition. In this context, this study aimed to evaluate the effect of the rock dusts siltstone, tephrite, and olivine melilitite pure or combined and associated or not with cattle manure on the chemical composition of soybean seeds of the cultivar BRS 232 grown on a Cambisol and Nitisol subjected to these treatments and conventional fertilization. For this, an experiment was carried out with pots in a greenhouse using a Cambisol and Nitisol to cultivate the soybean from January to May 2019 until seed production. The seeds were harvested, ground, and sieved through a 1 mm mesh sieve to determine the nutrient, phytate, and crude protein contents. The effects of the rock dusts on the chemical composition of seeds were directly related to the chemical characteristics of the evaluated soils. The tested rock dusts had a more pronounced response in the Cambisol (poorer soil) than in the Nitisol (more fertile). The contents and accumulation of nutrients in the seeds, as well as the total dry matter production in both soils subjected to the treatments with the rock dusts olivine melilitite and siltstone + olivine melilitite, pure and combined with manure, were similar and, in some cases, higher than the treatments subjected to conventional fertilization. The combination of manure and rock dusts provided an increase in the concentration of nutrients in both soils, resulting in their higher availability for plants and directly reflecting on the chemical composition of seeds.
