ABSTRACT The objectives of this study were to estimate genetic parameters and the repeatability coefficient and to select clones of elephant grass from full-sib families. Fifteen clones and two commercial controls were evaluated in a randomized block design with three replications. Three measurements were taken at regular 10-month intervals. Genotypic variance was significant. The observed heritability based on the mean of the genotypes (0.58), coupled with the results of repeatability (0.53) and selection accuracy (0.76), demonstrates that the genotypes performance is constant between measurements. Thus, only three measurements are necessary to reliably select genotypes and obtain real genetic gains with selection. Among the 15 clones evaluated, six showed higher new means than those of the BRS Capiaçu and BRS Canará controls and can be used as parents and/or to compose value for cultivation and use experiments aimed at the release of cultivars for bioenergy production. fullsib full sib families replications 10month month 10 intervals significant 0.58, 058 0.58 , 0 58 (0.58) 0.53 053 53 (0.53 0.76, 076 0.76 76 (0.76) Thus 1 andor or production 05 0.5 5 (0.58 (0.5 07 0.7 7 (0.76 0.

Resumo Introdução: O período pós-parto é um momento em que as mulheres são expostas às disfunções da musculatura do assoalho pélvico (DMAP) devido ao período gestacional, mas ainda faltam evidências de qualidade que avaliem o efeito de intervenções sobre a recuperação da musculatura do assoalho pélvico de mulheres no pós-parto. Objetivo: Investigar o efeito do treinamento dos músculos do assoalho pélvico (TMAP) e do low pressure fitness (LPF) sobre o incômodo relacionado às DMAP no pós-parto. Métodos: Estudo randomizado, controlado por placebo, com 35 mulheres que tiveram o parto realizado no Hospital Universitário Materno Infantil (HUMAI), na cidade de Ponta Grossa, Paraná. Foram testados os efeitos do LPF e do TMAP em três grupos: LPF (n = 12), TMAP (n = 12) e intervenção mínima/placebo (IM, n = 11). Os três grupos receberam as intervenções de forma on-line. Resultados: Os treinamentos com LPF e TMAP apresentaram melhores resultados em comparação à IM em alguns distúrbios relacionados às DMAP após 12 semanas de tratamento. O LPF foi mais eficaz sobre o escore global do Pelvic Floor Bother Questionnaire em 6 e 12 semanas, sobre incontinência urinária de esforço em 12 semanas e sobre dispareunia em 6 e 12 semanas.

Abstract Introduction: The postpartum period is a phase when women are susceptible to pelvic floor muscle dysfunction (PFMD) due to the gestational period; however, there is still a lack of quality evidence evaluating the effects of interventions on pelvic floor muscle recovery in postpartum women. Objective: To investigate the effects of pelvic floor muscle training (PFMT) and low presure fitness (LPF) on discomforts associate with PFMD during the postpartum period. Methods: A randomized, placebo-controlled study was conducted with 35 women who gave birth at the Maternal and Child University Hospital (HUMAI) in the city of Ponta Grossa, Brazil. The study tested the effects of LPF and PFMT across three groups: LPF (n = 12), PFMT (n = 12), and minimal intervention/placebo (MI, n = 11). The three groups received the interventions online. Results: Training with LPF and PFMT resulted in better outcomes compared to MI for some disorders associated with PFMD after 12 weeks of treatment. LPF was most effective in improving the global score of the Pelvic Floor Bother Questionnaire (PFBQ) at 6 and 12 weeks, in reducing stress urinary incontinence at 12 weeks, and in alleviating dyspareunia at 6 and 12 weeks. Conclusion: LPF and PFMT can effectively reduce discomfort associated with PFMD during the postpartum period.

Abstract Air contamination in confined environments can lead to severe health damage. Searching for effective and sustainable technologies that might bring quality to indoor air is necessary. Heterogeneous photocatalysis has been studied for its ability to oxidize, inactivating microorganisms in the air. In the present work, a reactor was assembled, where titanium dioxide (TiO2) P25 was incorporated into the inner face of polyvinyl chloride (PVC) tubes and vegetable sponges (Luffa sp.). Polyester Orthophthalic (PO) resin was used to fix the TiO2 onto the surfaces. Ultraviolet lamps (UVA) were used to activate the TiO2 catalyst to test the inactivation capacity of microorganisms, as they are economical and present high energy efficiency and long service life. The inactivation of microorganisms was evaluated in natural and artificially contaminated atmospheres. The photocatalytic reactor proved efficient in most tests in both atmospheres. In tests 1 and 2, no bacterial colony-forming units (CFUs) were found in the photocatalysis tube. In test 3, the average of 5 CFUs of fungi in the photocatalysis tube and 12.67 in the control tube was found, indicating inactivation. Therefore, this research is essential for presenting an alternative solution for indoor air treatment. damage necessary oxidize work assembled TiO (TiO2 P P2 PVC (PVC Luffa sp.. sp sp. . sp.)

Resumen El estudio de la confianza interpersonal es crucial para el desarrollo psicosocial humano. Se ha observado que, durante la niñez, favorece el comportamiento moral y prosocial, los vínculos de amistad, la competencia social, la experiencia de emociones positivas y el rendimiento académico, entre otros aspectos. El presente trabajo tuvo por objetivo adaptar y validar la Cross Cultural Children Trust Beliefs Scale (CCCTBS), a fin de poder evaluar este constructo en población argentina. La muestra incluyó 348 niños (51.2 % mujeres; 48.8 % varones), de entre 8 y 12 años de edad (m = 10.58; DE = 1.31), quienes completaron la CCCTBS y una escala de apego. Se consiguió una versión conceptual y semánticamente equivalente a la original, con buenas propiedades psicométricas. La escala argentina conserva el mismo número de ítems y replica el modelo operacional de partida, constituido por tres bases principales de la confianza: fiabilidad (α = .76; ω = .80), confianza emocional (α = .72; ω = .78) y honestidad (α = .78; ω = .83). Las puntuaciones de la CCCTBS correlacionaron positiva y significativamente con la medida de apego seguro, lo que aporta evidencias de su validez nomológica.

Abstract The study of interpersonal trust is crucial for human psychological development. It has been observed that it enhances moral and prosocial behavior during childhood, as well as friendship bonds, social competence, experience of positive emotions and academic performance, among others. This research aimed to adapt and validate the Cross-Cultural Children Trust Beliefs Scale (CCCTBS), to assess this construct in the Argentine population. The sample included 348 children (51.2 % female; 48.8 % male) aged 8 to 12 years (m = 10.58; SD = 1.31), who completed the CCCTBS and an attachment scale. A version, conceptually and semantically equivalent to the original was obtained, with good psychometric properties. The Argentine scale retains the same number of items and replicates the starting operational model, consisting of three main bases of trust: reliability (α = .76; ω = .80), emotional trust (α = .72; ω = .78) and honesty (α = .78; ω = .83). The CCCTBS scores correlated positively and significantly with the secure attachment measure, providing evidence of its nomological validity.

Abstract Introduction: there is an association between time of diagnosis and prognosis in cancer patients. The non-oncologist physician is usually the first healthcare provider to establish contact with the patient, therefore, they must have an adequate clinical approach. Methodology: a narrative review was conducted, where an extensive search of the literature was performed in databases (PubMed, Scopus, Web of Science), and the most up-to-date articles were selected. Approach: a complete medical history, a thorough physical examination, and the recognition of possible oncologic emergencies should be carried out. For treatment, histological confirmation is mandatory, and efforts should be directed towards achieving this goal. The study of pleural, pericardial, and peritoneal fluid can provide a quick and non-invasive histological diagnosis, allowing for the initiation of treatment. In cases where there are no effusions, biopsies should be taken from the most representative and easily accessible lesions. Routine endoscopic studies should be avoided in patients without symptoms of gastrointestinal neoplasia, as well as tumor markers that are not accurate and may confuse the diagnostic process. Conclusion: a correct clinical approach that allows for a precise and timely diagnosis is indispensable.

Resumen Introducción: existe asociación entre el tiempo del diagnóstico y el pronóstico en pacientes con cáncer. El médico no oncólogo es quien establece el primer contacto con la persona, por lo que debe hacer un enfoque clínico adecuado. Metodología: se realizó una revisión narrativa en donde se hizo una búsqueda extensiva de la literatura en bases de datos (PubMed, Scopus, Web of Science), se seleccionaron los artículos más actualizados. Enfoque: se debe llevar a cabo una historia clínica, un examen físico completo y reconocer las posibles urgencias oncológicas. Para el tratamiento es mandatario tener confirmación histológica por lo que los esfuerzos deben estar dirigidos a este objetivo. El estudio del líquido pleural, pericárdico y peritoneal pueden aportar un diagnóstico histológico ágil y poco invasivo, que permita iniciar tratamiento. En caso de no tener efusiones, se deberá tomar biopsia de las lesiones más representativas y de más fácil acceso. Se debe evitar la toma rutinaria de estudios endoscópicos en pacientes sin síntomas de neoplasia gastrointestinal, al igual que marcadores tumorales que no son precisos y confunden en el proceso diagnóstico. Conclusión: es indispensable un enfoque clínico correcto que permita un diagnóstico preciso y oportuno.

Abstract Background Diversified crop systems provide several advantages for crop production and the agricultural ecosystem. In contrast, growing the same crop for consecutive years increases weeds, insects, and diseases issues, adding further cost to crop production owing to their management. Objective The objective was to evaluate the effects of six different winter cover crops and compare the impacts of a diversified rotation system in contrast to the succession system, combined with three different post-emergence herbicide management looking up to soybean yield, aboveground mass production, and weed density impact. Methods The experiment was performed over 2014 to 2018, using a randomized block design with four replications. Cover crop treatments were 1) fallow 2) wheat 3) rye 4) rye + turnip 5) rye + vetch 6) black oats. At the time of cover crop termination, weed density was counted and aboveground mass was measured. The crop rotation system was an alternated soybean and corn using three different post-emergence herbicide treatments, and the succession system was soybean each year. When a significant effect was observed after test F, the Tukey test (p ≤ 0.05) was applied to compare treatment effects. Results Rye + vetch as a cover crop, rotation system, and herbicide usage showed a higher impact on weed density. Rye + turnip has produced more aboveground biomass. Soybean yield was higher after wheat. Conclusions Cover crops implementation, crop rotation system, and herbicide usage have increased biomass production and crop yield, and reduced weed density showing integrated weed management as a key strategy for production systems. ecosystem weeds insects issues postemergence post emergence 201 2018 replications 1 2 3 4 5 6 oats termination measured year F p 0.05 005 0 05 implementation 20 0.0 00 0.

ABSTRACT Enlist™ technology confers resistance to 2,4-D herbicides, glyphosate, and ammonium glufosinate for soybeans. However, the application of herbicides to plants can generate stress, even in resistant crops. Thus, here we evaluated whether the application of herbicides in transgenic soybean farms, resistant to these herbicides, adversely affects the activity of antioxidant enzymes and porphobilinogen formation by delta-aminolevulinate dehydratase (ALA-D) activity. At seven days after herbicide application, the aerial part of the plants was collected and used to determine the activity of antioxidant enzymes as catalase, ascorbate peroxidase, and guaiacol peroxidase, such as lipid peroxidation levels and the activity of the ALA-D enzyme. At seven days after herbicide application, the aerial part of plants was collect and used to determine the activity of antioxidant enzymes, such as catalase, ascorbate peroxidase and guaiacol peroxidase, as well as the levels of lipid peroxidation and the activity of the ALA-D enzyme. The activity of important antioxidant enzymes involved in the scavenging of reactive oxygen species (ROS) was increased in the soybean cultivar with the Enlist™ technology, while no severe damage to lipids was detected. However, the activity of ALA-D was inhibited, which could potentially impair the formation of porphobilinogen and decrease photosynthetic efficiency. Thus, these results indicate that herbicides can affect the activity of ROS-scavenging enzymes even in transgenic, herbicide-resistant plants.

RESUMO: O Modelo de Cadeia Estocástica de Markov e o Processo de Hierarquia Analítica (AHP) foram utilizados como ferramentas de apoio à tomada de decisão para a melhor escolha de plantio na cidade de Caxias do Sul, Brasil. As informações de temperatura e precipitação foram coletadas de 1997 a 2017 no Banco de Dados Meteorológicos para Ensino e Pesquisa do Instituto Nacional de Meteorologia do Brasil. O modelo estocástico foi aplicado para obtenção da probabilidade de transição entre faixas de variação para temperatura e precipitação. Na segunda fase do estudo, um modelo algébrico foi desenvolvido, possibilitando vincular a probabilidade da matriz de transição de cadeias de Markov na matriz de julgamento do AHP. Na terceira fase, o AHP foi aplicado como ferramenta de apoio à decisão do cultivo mais benéfico para a cidade estudada, considerando os critérios avaliados: temperatura, precipitação e pH do solo. As alternativas escolhidas para fazer o ranking foram: cenoura, tomate, maçã e uva, escolhidas por possuírem a maior quantidade de plantio na cidade de Caxias do Sul. O ranking do resultado de força de benefício da aplicação do modelo para a primavera foi: cenoura (0,297), maçã (0,259), uva (0,228) e tomate (0,215); para o verão: uva (0,271), tomate (0,261), maçã (0,238) e cenoura (0,230); para o outono: cenoura (0,316), uva (0,243), tomate (0,228) e maçã (0,213); para o inverno: cenoura (0,327), tomate (0,235), maçã (0,222) e uva (0,216). Assim, concluiu-se que o agricultor terá mais chances de sucesso se optar por plantar cenoura durante a primavera, outono e inverno, e uva durante o verão.

ABSTRACT: The Markov stochastic chain model and the analytical hierarchy process (AHP) were used as tools to support decision-making for the best crop-planting choice in the city of Caxias do Sul, Brazil. Temperature and precipitation information were collected from the Meteorological Database for Teaching and Research of the National Institute of Meteorology of Brazil for the period 1997-2017. The stochastic model was applied to obtain the probability of transition between a range of variations for temperature and precipitation. In the second phase of the study, an algebraic model was developed, making it possible to link the probability of the Markov chain transition matrix to the AHP judgment matrix. In the third phase, the AHP was applied as a tool to determine the most beneficial crop that could be planted for the studied city, considering the evaluated criteria: temperature, precipitation, and soil pH. The alternatives for crop planting were carrots, tomatoes, apples, and grapes. These were chosen because they are the most-planted crops in the city of Caxias do Sul. The ranking of the benefit-force results of applying the model for spring was carrots (0.297), apples (0.259), grapes (0.228), and tomatoes (0.215); for summer: grapes (0.261), tomatoes (0.261), apples (0.238), and carrots (0.230); for autumn: carrots (0.316), grapes (0.243), tomatoes (0.228), and apples (0.213); and for winter: carrots (0.327), tomatoes (0.235), apples (0.222), and grapes (0.216). Thus, it was concluded that farmers would have a better chance of success if they planted carrots during the spring, autumn, and winter, and grapes during the summer.

RESUMO Este trabalho tem por objetivo analisar a prevalência de lesões traumato-ortopédicas e fatores associados em atletas inscritos na Federação Paranaense de Basquete em Cadeira de Rodas no ano de 2017. Participaram da pesquisa 58 atletas de Basquete em Cadeira de Rodas (BCR) com média de idade de 35,75 (±11,21) anos. Foram verificadas a frequência e a distribuição das lesões traumato-ortopédicas ocorridas nos últimos 12 meses por meio de um questionário adaptado do instrumento do Laboratório de Prevenção e Reabilitação de Lesões Esportivas e do instrumento da National Injury Recording System. A força e o sentido da associação entre a presença de lesões e fatores associados foram analisadas por meio do teste de regressão de Poisson. Todo o tratamento estatístico foi realizado com auxílio do programa SPSS, versão 15.0 for Windows. Foram encontradas associações significativas entre a presença de lesões e o tempo de prática do BCR, uso da cadeira de rodas, treinamento paralelo e uso de muleta ou bengala. Concluiu-se que são necessárias políticas públicas para o incentivo de projetos interdisciplinares, a fim de garantir o atendimento integral da pessoa com deficiência, considerando que a promoção da saúde física é uma das diretrizes da Política Nacional de Saúde da Pessoa com Deficiência.

ABSTRACT This study aims to analyze the prevalence of trauma-orthopedic injuries and associated factors in athletes enrolled in the Federação Paranaense de Basquete em Cadeira de Rodas in 2017. Fifty-eight Wheelchair Basketball (WB) athletes participated in the research with an average of age of 35.75 (±11.21) years. The frequency and distribution of trauma and orthopedic injuries occurred in the last 12 months were verified through a questionnaire adapted from the instrument of the Laboratório de Prevenção e Reabilitação de Lesões Esportivas and the instrument of the National Injury Recording System. The strength and direction of the association between the presence of injuries and associated factors were analyzed using the Poisson regression test. All statistical treatment was performed using the SPSS program, version 15.0 for Windows. Significant associations were found between the presence of injuries and the time of WB practice, use of a wheelchair, parallel training and use of a crutch or cane. It was concluded that public policies are needed to encourage interdisciplinary projects in order to ensure comprehensive care for people with disabilities, considering that the promotion of physical health is one of the guidelines of the National Health Policy for People with Disabilities.

Abstract Introduction: We investigated the clinical course and outcomes of patients submitted to cardiovascular surgery in Brazil and who had developed symptoms/signs of coronavirus disease 2019 (COVID-19) in the perioperative period. Methods: A retrospective multicenter study including 104 patients who were allocated in three groups according to time of positive real time reverse transcriptase-polymerase chain reaction (RT-PCR) for the SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2): group 1, patients who underwent cardiac surgery > 10 days after positive RT-PCR; group 2, patients with a positive RT-PCR within 10 days before or after surgery; group 3, patients who presented positive RT-PCR > 10 days after surgery. The primary outcome was mortality and secondary outcomes were postoperative complications, intensive care unit (ICU) length of stay, and postoperative days of hospitalization. Results: The three groups were similar with respect to age, the European System of Cardiac Operative Risk Evaluation score, and comorbidities, except hypertension. Postoperative complications and death were significantly higher in groups 2 and 3 than in group 1, and no significant difference between groups 2 and 3 was seen. Group 2 showed a high prevalence of surgery performed as an urgent procedure. Although no significant differences were observed in ICU length of stay, total postoperative hospitalization time was significantly higher in group 3 than in groups 1 and 2. Conclusion: COVID-19 affecting the postoperative period of patients who underwent cardiovascular surgery is associated with a higher rate of morbidity and mortality. Delaying procedures in RT-PCR-positive patients may help reduce risks of perioperative complications and death.

ABSTRACT The inefficiency of conventional methods for removal surfactants and pathogens from wastewater has led to developing alternative treatments, such as the Fenton process and its variants. In this study, the conventional Fenton process and modified Fenton process with ethylenediaminetetraacetic acid (EDTA) were applied to reduce surfactants and fecal coliforms as a complementary treatment for wastewater in Quito, Ecuador. Initially, the conditions for hydrogen peroxide (H 2 O 2 ) concentration, molar ratio Fe 2+: H 2 O 2 , and stirring were established for a conventional Fenton process; these conditions were after applied in a modified Fenton process with EDTA in which the conditions for the molar ratio Fe 2+: EDTA and pH were defined. The best experimental conditions were: H 2 O 2 concentration of 124.4 mM, a continuous stirring of 130 rpm, molar ratio EDTA:Fe2+: H 2 O 2 of 1:1:20, and pH of 6.41. With these conditions, from a sample with an initial concentration of surfactants, fecal coliforms, and COD of 6.12 mg/L, 71000 CFU/mL, and 980 mg/L, respectively, total inactivation of fecal coliforms was achieved, and it was obtained a reduction of 97% for surfactants and 93% for chemical oxygen demand after 15 min of treatment. The final concentration of these pollutants met water quality standards, according to the Environmental Protection Agency (EPA). This treatment could be potentially applied to treat wastewater dealing with the same problem.

RESUMEN La ineficiencia de los métodos convencionales para remover tensoactivos y patógenos de aguas residuales ha derivado en la necesidad de desarrollar tratamientos alternativos, como el proceso Fenton y sus variantes. En este estudio se aplicó un proceso Fenton convencional y modificado con ácido etilendiaminotetraacético (EDTA) como tratamiento complementario para aguas residuales rurales de Quito, Ecuador. Inicialmente, se establecieron las condiciones de concentración de peróxido de hidrógeno (H2O2), la relación molar Fe2+:H2O2 y requerimiento de agitación para un proceso Fenton convencional. Estas condiciones se adaptaron a un proceso Fenton modificado con EDTA- en el cual se definieron las condiciones de relación molar Fe2+:EDTA y de pH. Las mejores condiciones establecidas fueron: concentración de H2O2 de 124,4 mM, agitación continua de 130 rpm, relación molar EDTA:Fe2+:H2O2 de 1:1:20 y pH de 6,41 (pH del efluente). Bajo estas condiciones, a partir de una muestra con concentración inicial de tensoactivos, coliformes fecales y DQO de 6,12 mg/L, 71000 UFC/mL y 980 mg/L, respectivamente, se alcanzó inactivación total de coliformes fecales y una reducción de 97% para tensoactivos y 93% para la demanda química de oxígeno a los 15 min de tratamiento. La concentración final de estos contaminantes cumplió con los estándares establecidos por la Agencia de Protección Ambiental (EPA). Este tratamiento podría, potencialmente, ser aplicado para complementar el tratamiento de aguas residuales que presenten problemas similares.

Resumo Objetivo Avaliar a confiabilidade da obtenção do ângulo crítico do ombro (ACO) na ressonância magnética (RM) comparada com esse mesmo ângulo obtido por meio de radiografias, e avaliar a curva de aprendizado do método. Métodos As imagens de radiografias e RMs de 15 pacientes foram avaliadas prospectivamente de forma cega e randômica. O ACO foi medido e comparado entre os grupos e subgrupos. Resultados A média dos ACOs nas imagens de radiografia foi de 34,61º ± 0,67, e, na RM, 33,85º ± 0,53 (p = 0,29). Não houve diferença estatisticamente significativa. Houve curva de aprendizado progressiva na regressão linear entre os subgrupos, de especializando em ombro a especialista e radiologista. Conclusão Não houve diferença estatisticamente significativa entre o ACO por imagens de radiografia e RM. O método da RM parece ter sua eficiência associada a avaliadores mais experientes. Independente da experiência do avaliador, a variabilidade dos dados foi menor nas avaliações por RM.

Abstract Objective To evaluate the feasibility of magnetic resonance imaging (MRI) to obtain the critical shoulder angle (CSA) comparing the results obtained through radiography and MRI, and assess the learning curves. Methods In total, 15 patients were evaluated in a blinded and randomized way. The CSA was measured and compared among groups and subgroups. Results The mean angles measured through the radiographic images were of 34.61 ± 0.67 and the mean angles obtained through the MRI scans were of 33.85 ± 0.53 (p = 0.29). No significant differences have been found among the groups. The linear regression presented a progressive learning curve among the subgroups, from fellow in shoulder surgery to shoulder specialist and radiologist. Conclusion There was no statistically significant difference in the X-rays and MRI assessments. The MRI seems to have its efficacy associated with more experienced evaluators. Data dispersion was smaller for the MRI data regardless of the experience of the evaluator.

Abstract The age and growth of Pseudoplatystoma corruscans, is analyzed on specimens landed in Puerto Antequera, Province of Chaco, Argentina. The study is based on length frequency distribution of 1192 individuals and growth marks of 293 pectoral spines. Previously to age assignation based on spines readings, we performed analyses that ruled out age-associated resorption of rings and corroborated the annual periodicity of mark formation. The average sizes of the radius of each ring were obtained, and the total length of fish were back-calculated to the time of the ring formation, by the regression model fitted between the total radius of the spines to the respective sizes of each fish. Such data showed a good fitting to growth models of von Bertalanffy, Gompertz and logistic for both sexes separately. Results indicate that the study of the species growth must be carried out for each sex separately and that the fishing regulations must consider this characteristic of the species since the current management guidelines could be promoting differential capture by sexes.

Resumen En este trabajo se analiza el crecimiento y la edad del Pseudoplatystoma corruscans, a partir de ejemplares desembarcados en el Puerto Antequera, provincia de Chaco, Argentina. El estudio se basó en la distribución de frecuencias de tallas de 1192 individuos y marcas de crecimiento en 293 espinas pectorales. Para asignar las edades a partir de las lecturas se realizaron análisis que permitieron descartar la reabsorción de anillos asociada a la edad y corroborar la periodicidad anual de la formación de marcas. Se obtuvieron los tamaños medios de los radios de cada anillo y se retrocalcularon las tallas al momento de su formación, mediante la relación del radio total de las espinas con las tallas respectivas de cada pez. Dichos datos mostraron un buen ajuste a las curvas de crecimiento de von Bertalanffy, Gompertz y logística para ambos sexos por separado. Los resultados demostraron que el estudio del crecimiento de la especie debe realizarse para cada sexo por separado y que las normas pesqueras deben contemplar esta característica de la especie ya que las actuales pautas de manejo podrían estar promoviendo la captura diferencial por sexos.

Resumo A vigilância popular ambiental (VPA) promove o protagonismo dos sujeitos em situação de vulnerabilidade ambiental na produção e avaliação de dados sobre a poluição a que estão submetidos. O objetivo deste trabalho foi analisar as experiências de VPA desenvolvidas em duas localidades impactadas por siderúrgicas: Santa Cruz/RJ e Piquiá de Baixo/MA. Nesses locais foram realizadas atividades de monitoramento ambiental comunitário (MAC) dos níveis de material particulado de 2,5 micrômetros (MP2,5) na atmosfera, entre novembro de 2016 e julho de 2017, utilizando equipamento monitor de qualidade do ar de baixo custo e fácil operação. As médias mensais dos níveis de MP2,5 em Piquiá e Santa Cruz foram elevadas, a depender da época avaliada, pois ultrapassaram a média anual recomendada pela Organização Mundial de Saúde (OMS), de 10 µg/m3, e por várias vezes a média diária recomendada, de 25 µg/m3. A ideia principal desta proposta de monitoramento consistiu em estabelecer, com o engajamento das comunidades atingidas, um processo capaz de apresentar um contraponto às informações oficiais sobre cenários locais de poluição atmosférica. Os dados de poluição produzidos possibilitam que essas comunidades tenham uma atuação mais qualificada nos espaços públicos de debate e tomada de decisão.

Abstract Environmental surveillance by the people fosters the protagonism of individuals in a situation of environmental vulnerability to generate and evaluate data regarding the pollution to which they are exposed. The scope of this work was to analyze such experiences in two areas impacted by the steel industry: Santa Cruz/RJ and Piquiá de Baixo/MA. At these sites, community environmental monitoring (CEM) activities were conducted to measure 2.5 micrometer particulate matter (PM2.5) levels in the atmosphere, between November/2016 and July/2017. Such activities were conducted using a low-cost and easy-to-operate air quality monitor. Monthly averages of PM2.5 levels in Piquiá and Santa Cruz were high, depending on the period assessed, since they surpassed the annual average recommended by the World Health Organization (WHO) of 10 µg/m3, and, on several occasions, the recommended daily average of 25 µg/m3. The main idea of this monitoring proposal was to establish a process capable of presenting a counterpoint to official information on local atmospheric pollution scenarios, with the involvement of affected communities. The pollution data produced enable these communities to participate in public debates and decision-making processes in a more informed way.
