Abstract Introduction: Chronic kidney disease is usually asymptomatic, and its diagnosis depends on laboratory tests, with emphasis on serum creatinine and proteinuria. Objective: To assess knowledge on the role of serum creatinine as a biomarker of kidney function in a sample of the Brazilian population. Method: Cross-sectional observational study conducted in São Paulo (SP, Brazil), in which a random adult population was interviewed. Results: A total of 1138 subjects were interviewed, with a median age of 36 years old (27–52); 55.1% were female. Regarding the “creatinine” biomarker, 40.6% stated they had never performed such a test. When asked about their knowledge on the usefulness of this exam, only 19.6% knew its function. The other responses were “I don’t know” (71.6%), evaluating heart function (0.9%) and liver function (7.8%). Of those who reported they had already taken a creatinine test, only 29.4% correctly identified the role of creatinine. When dividing the groups into “knows” and “does not know” the function of creatinine, a statistically significant difference (p < 0.05) was observed regarding level of education, female sex, being a healthcare student/worker, having ever measured creatinine, knowing someone with kidney disease and older age. In the multivariate analysis, the main variable related to knowing the creatinine role was having previously taken the test (OR 5.16; 95% CI 3.16–8.43, p < 0.001). Conclusion: There is a significant lack of knowledge about creatinine and its use in checkups. The results indicate that greater efforts are needed from healthcare professionals to raise awareness on the role of serum creatinine.

Resumo Introdução: A doença renal crônica costuma ser assintomática e seu diagnóstico depende da realização de exames laboratoriais, com destaque para a creatinina sérica e pesquisa de proteinúria. Objetivo: Avaliar em uma amostra da população brasileira o conhecimento sobre o papel da creatinina sérica como marcador de função renal. Método: Estudo observacional transversal realizado na cidade de São Paulo (SP, Brasil), em que foi entrevistada uma população adulta aleatória. Resultados: Foram entrevistados 1138 indivíduos, com idade mediana de 36 anos (27–52); 55,1% do sexo feminino. Com relação ao marcador “creatinina”, 40,6% afirmaram que nunca realizaram tal dosagem. Quando questionados quanto ao conhecimento sobre a utilidade desse exame, somente 19,6% sabiam a sua função. As outras respostas foram “não sei” (71,6%), avaliar o funcionamento do coração (0,9%) e fígado (7,8%). Dos que afirmaram já terem realizado o exame de creatinina, somente 29,4% acertaram a função da creatinina. Ao dividir os grupos em “sabe” e “não sabe” a função da creatinina, percebeu-se diferença estatisticamente significante (p < 0,05) em relação ao grau de escolaridade, sexo feminino, ser aluno/trabalhador da saúde, ter dosado creatinina alguma vez, conhecer alguém com doença renal e maior idade. Na análise multivariada, a principal variável relacionada com conhecer a função da creatinina foi ter realizado o exame anteriormente (OR 5,16; IC 95% 3,16–8,43, p < 0,001). Conclusão: Há grande desconhecimento sobre a creatinina e seu uso em check-ups. Os resultados indicam que é necessário maior esforço por parte dos profissionais de saúde para divulgar o papel da creatinina sérica.

ABSTRACT BACKGROUND: Considering the ability of the health and self-management in diabetes questionnaire (HASMID-10) to verify the impact of self-management on diabetes, we highlight its relevance to scientific research and clinical applicability. However, to date, no study has been conducted to scientifically support its use in other languages. OBJECTIVE: To translate, cross-culturally adapt, and validate the HASMID-10 into the Brazilian Portuguese. DESIGN AND SETTING: A translation, cross-cultural adaptation, and validation study conducted at Ceuma University. METHODS: Study was conducted in accordance with the Guidelines for the Process of Cross-Cultural Adaptation of Self-Report Measures and Consensus-based Standards for the Selection of Health Measurement Instruments. We included participants of both sexes diagnosed with diabetes, aged between 18 and 64 years, and without cognitive deficits or any other limitations that would prevent them from answering the questionnaire. We assessed participants using the problem areas in diabetes (PAID) scale and HASMID-10. We assessed reliability using a test-retest model with a 7-day interval between assessments. We used intraclass correlation coefficient (ICC), 95% confidence interval (CI), standard error of measurement (SEM), minimum detectable difference (MDD), Spearman correlation coefficient, and floor and ceiling effects. RESULTS: Sample comprised 116 participants, most of whom were women, overweight, non-practitioners of physical activity, and nonsmokers. We observed significant correlations (P = 0.006; rho = −0.256) between the HASMID-10 and PAID, adequate reliability (ICC = 0.780) and internal consistency (Cronbach's alpha = 0.796). No ceiling or floor effects were observed. CONCLUSION: HASMID-10 has adequate measurement properties and may be used for Brazilians.

ABSTRACT Zinnia sp. and hairy beggartick (Bidens pilosa) plants exhibiting symptoms of possible virus infection were found in the municipality of Santa Bárbara d’Oeste, São Paulo State, Brazil. Flexuous filamentous particles and cytoplasmatic inclusions typical of potyvirus infection were observed by transmission electron microscopy, respectively, in leaf extracts and cells of symptomatic leaves. Infection of both plants with bidens mottle virus (BiMoV) was confirmed by RT-PCR using potyvirus universal primers, followed by nucleotide sequencing of the amplicons. The nearly complete genome sequence of the Brazilian isolate, named BiMoV-BR, is 9700 nucleotides long and shares 95.6 % identity with the corresponding nucleotide sequence of a BiMoV isolate from the United States. BiMoV-BR was mechanically transmitted and caused systemic infection on plants of Zinnia sp., hairy beggarstick, sunflower (Helianthus annuus), and lettuce (Lactuca sativa). Myzus persicae transmitted the virus to Zinnia sp. plants with efficacy of 8 % and 42 %, using one and ten aphids per plant, respectively. This is the first detection of BiMoV in Brazil. Further studies are necessary to evaluate the distribution of this potyvirus in the country.

ABSTRACT BACKGROUND: Specific types of violence such as intimate partner sexual violence and intimate partner homicide occur more frequently in rural areas. OBJECTIVE: This study aimed to systematically review the literature on the knowledge and attitudes of rural healthcare providers regarding cases of domestic violence against women. DESIGN AND SETTING: Systematic review developed at Universidade Federal de Uberlândia. METHODS: We conducted an electronic search of six databases, which only included observational studies, regardless of the year, language, or country of publication, except for studies that used secondary data and were exclusively qualitative. Two reviewers performed the selection, data extraction, and risk of bias assessment using a specific Joanna Briggs Institute tool. RESULTS: Six studies met the inclusion criteria. All the studies had a low risk of bias. Approximately 38% of these professionals identified injuries caused by violence in patients. When asked about knowing the correct attitude to take in cases of confirmed violence, between 12% and 64% of rural healthcare providers answered positively; most of them would refer to specialized institutions and promote victim empowerment and counseling. The number of professionals with an educational background in the field ranged from 16% to 98%. CONCLUSIONS: The evident disparity across studies shows that some professionals have suboptimal knowledge and require training to adopt the correct attitude when identifying female victims of domestic violence in clinical practice. SYSTEMATIC REVIEW REGISTRATION: This systematic review was registered in the Open Science Framework Database under the registration http://doi.org/10.17605/OSF.IO/B7Q6S.

RESUMO No Brasil, a teoria do professor reflexivo vem sendo alvo de discussão em cursos de formação continuada e nos documentos oficiais orientadores de formação inicial. Entretanto, será que os professores desenvolvem uma prática reflexiva, ou essa prática fica só nas orientações documentais? Com o objetivo de responder a esse questionamento, realizamos uma pesquisa com quinze professores de uma escola pública localizada no estado de São Paulo, Brasil. Para essa pesquisa, baseamo-nos em três questões propostas por McKay (2008). Essas questões versaram sobre o planejamento das atividades pedagógicas, em que se baseavam para avaliar as suas aulas e em que momento refletiam sobre sua prática. Os resultados evidenciaram que a maioria segue o currículo do estado de São Paulo, e as reações dos alunos foram o parâmetro mais utilizado para a avaliação das aulas ministradas, nas quais os professores desenvolvem principalmente a reflexão na ação. Com essa pesquisa percebemos que para esse grupo de professores, torna-se importante um aprofundamento da reflexão sobre as suas práticas.

ABSTRACT In Brazil, the theory of reflective teacher has been the subject of discussion in continuing education courses and in the official documents that guide initial education. However, do teachers actually develop a reflective practice, or does such practice remains only in official guidelines? In order to answer this question, we conducted a research with fifteen teachers from a public school located in the state of São Paulo, Brasil. For this research, we based ourselves on three questions proposed by McKay (2008). These questions were about the planning of pedagogical activities, what they used to evaluate their classes and when they reflected on their practice. The results showed that most of the teachers follow São Paulo state curriculum; and the students’ reactions were the most used parameter for the evaluation of their classes, in which teachers mainly develop the reflection on action. With this research we realized that for this group of teachers, it is important to deepen the reflection on their practices.

Abstract This study aimed to evaluate the effect of apicoectomy performed with a bur or an ultrasonic tip on the adaptation of the filling material to root canal dentin. Twenty human mandibular incisors were selected and prepared with a ProDesign Logic system up to diameter 40/.05. The root canals were filled with Bio-C Sealer (Angelus, PR, Brazil) using the single cone technique and were stored at 37ºC and 95% relative humidity for 7 days. After this period, the apicoectomy of the 3 millimeters of the root apex was performed using Endo-Z bur (Dentsply Sirona) or Bladesonic ultrasonic tip (Helse Ultrasonic, Santa Rosa de Viterbo, Brazil) (n=10). The specimens were scanned by micro-computed tomography (micro-CT; SkyScan 1176) with a voxel size of 8.74 µm after obturation and after apicoectomy. The percentage of voids at the interface between the filling material and the root canal wall was evaluated in the apical 4 mm of the root after apicoectomy, besides the time cutting to both devices. The data obtained were submitted to paired and unpaired t-tests (α = 0.05). Endo-Z and Bladesonic increased the percentage of voids between the filling material and the dentin after apicectomy (p<0.05), and they were similar (p>0.05). Endo-Z has a shorter time to perform apicoectomy compared to Bladesonic (p<0.05). Apicectomies with Endo-Z or Bladesonic could harm the material/dentin interface, while the Endo-Z bur was faster than the Bladesonic ultrasonic tip.

Resumo O objetivo deste estudo foi avaliar o efeito da apicectomia realizada com broca ou inserto ultrassônico na adaptação do material obturador á dentina do canal radicular. Vinte incisivos inferiores humanos extraídos foram selecionados e preparados com o sistema ProDesign Logic até o diâmetro 40/.05. Os canais radiculares foram obturados com Bio-C Sealer (Angelus, PR, Brasil) por meio da técnica de cone único e foram armazenados em estufa a 37ºC e umidade relativa de 95% por 7 dias. Após esse período, foi realizada apicectomia dos 3 milímetros apicais utilizando broca Endo-Z (Maillefer - Dentsply) ou inserto ultrassônico BladeSonic (Helse Ultrasonic, Santa Rosa de Viterbo, Brasil) (n=10). Os espécimes foram escaneados por meio de microtomografia computadorizada (micro-CT; SkyScan 1176) com tamanho de voxel de 8,74 µm após obturação e após apicectomia. Please, correct this sentece to O percentual de falhas na interface entre o material obturador e a parede dentinaria foi avaliado nos 4 mm apicais da raiz apos apicectomia, alem do tempo de corte para ambos dispositivos. Os dados obtidos foram submetidos aos testes t pareado e não pareado (α = 0,05). Endo-Z e Bladesonic aumentaram o percentual de vazios entre o material obturador e a parede da dentina após apicectomia (p<0.05), sendo semelhantes entre si (p>0.05). Endo-Z demonstrou menor tempo para realizar apicectomia em comparação com Bladesonic (p<0.05). Apicectomias com Endo-Z ou Bladesonic podem prejudicar a interface material obturador/dentina, sendo a broca Endo-Z mais rápida que a ponta ultrassônica Bladesonic.

Military police activity is a dangerous, stressful occupation that poses health risks. Nutritional habits, physical activity, body composition and perceived stress, in addition to being interrelated, influence components of professional performance, such as work motivation, general self-efficacy and absenteeism. The objective was to compare nutritional habits, physical activity, body mass index and perceived stress of military police officers working in operational and administrative services, of both sexes, and to investigate the correlation between these variables. The Mann-Whitney U test was used for the comparative analysis and, for the correlational study, the Pearson correlation coefficient. Perceived stress and physical activity were inversely correlated (r=-0.268; p&lt;0.001). Nutritional habits correlated significantly: with physical activity (r=0.381; p&lt;0.001), directly; and, conversely, body mass index (r=0.256; p&lt;0.001) and perceived stress (r=-0.201; p&lt;0.01). Military police officers from the operational service had significantly higher body mass index (U=3695; p&lt;0.001) and physical activity (U=3776; p&lt;0.001) than their counterparts from the administrative service. Men had significantly higher body mass index (U=1333; p&lt;0.001) and physical activity (U=2205; p&lt;0.01) than women, who had significantly higher stress levels than men (U=1927; p&lt;0.001). The correlations and significant differences observed point to the need to implement personnel and health management policies aimed at improving the lifestyle, body composition and stress of military police officers. Study limitations and future directions are discussed.

La actividad de la policía militar es una ocupación peligrosa y estresante que presenta riesgos para la salud. Hábitos alimentarios, actividad física, composición corporal y estrés percibido, además de estar interrelacionados, influyen en componentes del desempeño profesional, como motivación para el trabajo, autoeficacia general y ausentismo. El objetivo fue comparar hábitos nutricionales, actividad física, índice de masa corporal y estrés percibido de policías militares que trabajan en servicios operativos y administrativos, de ambos sexos, e investigar la correlación entre estas variables. Para el análisis comparativo se utilizó la prueba U de Mann-Whitney y, para el estudio correlacional, el coeficiente de correlación de Pearson. Estrés percibido y actividad física se correlacionaron inversamente (r=-0,268; p&lt;0,001). Hábitos nutricionales correlacionaron significativamente: con actividad física (r=0,381; p&lt;0,001), directamente; y, por el contrario, con índice de masa corporal (r=0,256; p&lt;0,001) y estrés percibido (r=-0,201; p&lt;0,01). Los policías militares del servicio operativo presentaron índice de masa corporal (U=3695; p&lt;0,001) y actividad física (U=3776; p&lt;0,001) significativamente mayores que sus homólogos del servicio administrativo. Hombres tenían un índice de masa corporal significativamente mayor (U=1333; p&lt;0,001) y actividad física (U=2205; p&lt;0,01) que las mujeres, quienes tenían niveles de estrés significativamente más altos que los hombres (U=1927; p&lt;0,001). Las correlaciones y diferencias significativas observadas apuntan a necesidad de implementar políticas de gestión de personal y salud dirigidas a mejorar el estilo de vida, composición corporal y estrés de los policías militares. Se discuten limitaciones del estudio y direcciones futuras.

A atividade policial militar é uma ocupação perigosa, estressante e que impõe riscos à saúde. Os hábitos nutricionais, atividade física, composição corporal e estresse percebido, além de relacionarem-se entre si, influenciam componentes do desempenho profissional, tais como motivação para o trabalho, autoeficácia geral e absenteísmo. O objetivo deste estudo foi comparar hábitos nutricionais, atividade física, índice de massa corporal e estresse percebido de policiais militares que atuam no serviço operacional e administrativo, de ambos os sexos, e investigar a correlação entre essas variáveis. Utilizou-se o teste U de Mann-Whitney para a análise comparativa e, para o estudo correlacional, o coeficiente de correlação de Pearson. O estresse percebido e a atividade física correlacionaram-se inversamente (r=-0,268; p&lt;0,001). Os hábitos nutricionais correlacionaram-se significativamente: à atividade física (r=0,381; p&lt;0,001), diretamente; e, inversamente, ao índice de massa corporal (r=0,256; p&lt;0,001) e ao estresse percebido (r=-0,201; p&lt;0,01). Policiais militares do serviço operacional apresentaram índice de massa corporal (U=3695; p&lt;0,001) e atividade física (U=3776; p&lt;0,001) significativamente superiores aos seus congêneres do serviço administrativo. Homens apresentaram índice de massa corporal (U=1333; p&lt;0,001) e atividade física (U=2205; p&lt;0,01) significativamente superiores aos das mulheres, as quais apresentaram níveis de estresse significativamente superiores aos dos homens (U=1927; p&lt;0,001). As correlações e diferenças significativas observadas alertam para a necessidade de implementação de políticas de gestão de pessoal e de saúde voltadas à melhoria do estilo de vida, da composição corporal e do estresse de policiais militares. São discutidas limitações do estudo e direções futuras.

ABSTRACT Objective: Herein, we compared ambulatory blood pressure (ABP) between young adults with congenital adrenal hyperplasia (CAH) due to 21-hydroxylase enzyme (21OHase) deficiency and a control group. Additionally, we analyzed correlations between the glucocorticoid dose and androgen levels and ABP parameters. Subjects and methods: This case-control study included 18 patients (6 males and 12 females) and 19 controls (8 males and 11 females) matched by age (18-31 years). ABP monitoring was used to estimate blood pressure (BP) over a 24-h period. Results: No difference was noted between patients and controls in terms of systolic BP (males, 115.5 ± 5.6 vs. 117.0 ± 9.3, P = 0.733; and females, 106.4 ± 7.9 vs. 108.4 ± 7.6, P = 0.556, respectively) and diastolic BP during 24 h (males, 62.8 ± 7.5 vs. 66.2 ± 5.6, P = 0.349; and females, 62.7 ± 4.9 vs. 62.3 ± 4.9, P = 0.818, respectively). Systolic and diastolic BP and pulse pressure during daytime and nocturnal periods were similar between patients and controls. Furthermore, no differences were detected in the percentage of load and impaired nocturnal dipping of systolic and diastolic BP between patients and controls during the 24-h period. Additionally, the glucocorticoid dose (varying between r = −0.24 to 0.13, P > 0.05) and androgens levels (varying between r = 0.01 to 0.14, P > 0.05) were not associated with ABP parameters. Conclusion: No signs of an elevated risk for hypertension were observed based on ABP monitoring in young adults with CAH attributed to 21OHase deficiency undergoing glucocorticoid replacement therapy.

Abstract Objective To compare the level of quality of life and satisfaction after two years of total knee arthroplasties between individuals above and below 65 years of age and to identify predictor factors of poor clinical outcome and low level of satisfaction in patients undergoing arthroplasty. Methods This is a retrospective cohort with data from patients diagnosed with knee osteoarthritis submitted to primary total knee arthroplasty from 2014 to 2018 (n= 190). Clinical outcomes were assessed using the following scores: visual analog scale (VAS) of pain, EQ-5D-3L and EUROQOL-VAS (quality of life scales), patient satisfaction level, and functional scale of the Knee Injury and Osteoarthritis Outcome Score (KOOS), collected through a questionnaire applied preoperatively, as well as 1, 3, 12 and 24 months after surgery. Results Patients < 65 years old presented significantly lower values (clinical worsening) in KOOS-pain and KOOS-symptoms. There are no differences in the principal clinical scores that assess pain, function, and quality of life after the procedure, as well as in the rate of satisfaction with the procedure, among patients < 65 years old when compared with patients ≥ 65 years old. It was also observed that patients who were not satisfied with the procedure in the 24-month evaluation presented clinical results in some analyzed scores (KOOS-pain and EQ-VAS) similar to patients who declared themselves satisfied. Conclusion Scores that assess pain, function, quality of life, as well as satisfaction rate are similar between patients < 65 years old and those ≥ 65 years old.

Resumo Objetivo Comparar a qualidade de vida e satisfação 2 anos após a artroplastia total de joelho em indivíduos com idade ≥ e < 65 anos e identificar fatores preditivos de pior evolução clínica e baixo nível de satisfação nestes pacientes. Métodos Trata-se de uma coorte retrospectiva de dados de pacientes com diagnóstico de osteoartrite de joelho submetidos a artroplastia total primária de joelho entre 2014 e 2018 (n= 190). Os resultados clínicos foram avaliados de acordo com os seguintes escores: escala visual analógica (EVA) de dor, EQ-5D-3L e EUROQOL-VAS (escalas de qualidade de vida), nível de satisfação do paciente e escala funcional do Knee Injury and Osteoarthritis Outcome Score (KOOS, na sigla em inglês). Estes dados foram coletados por meio de questionário aplicado no período pré-operatório e 1, 3, 12 e 24 meses após a cirurgia. Resultados Os pacientes < 65 anos apresentaram valores significativamente menores (piora clínica) nas escalas KOOS-dor e KOOS-sintomas. Não houve diferenças nas principais pontuações clínicas de dor, função e qualidade de vida após o procedimento, nem no índice de satisfação com a cirurgia, entre pacientes < 65 anos em comparação com aqueles ≥ 65 anos. Observamos também que os pacientes não satisfeitos com o procedimento à avaliação de 24 meses apresentaram resultados clínicos em alguns escores analisados (KOOS-dor e EQ-VAS) semelhantes aos dos pacientes que se declararam satisfeitos. Conclusão Os escores que avaliam dor, função, qualidade de vida e índice de satisfação são semelhantes entre os pacientes < 65 anos e aqueles ≥ 65 anos.

RESUMO: Physalis peruviana L. (fisális) apresenta grande potencial econômico devido ao sabor diferenciado de seus frutos. A produtividade dos pomares brasileiros é baixa em função do número limitado de variedades ou cultivares disponíveis. O principal entrave na seleção de genótipos superiores é a falta de informação sobre a variabilidade genética dentro e entre as populações de fisális e, possivelmente, a base genética limitada das mesmas, que pode ser explicada pelos processos evolutivos, de domesticação e de seleção das populações naturais ou artificiais. A fisális cultivada atualmente no Brasil é tetraploide e tal poliploidia pode ter levado ao isolamento reprodutivo da espécie, o qual impede a ocorrência de hibridação intraespecífica. As populações cultivadas provêm de um pool genético comum e, além disso, sofreram um longo processo de domesticação e seleção realizadas empiricamente pelos agricultores. Porém, na Colômbia e em outros países andinos existem populações silvestres que exibem diversidade genética que, embora sejam fundamentais para a conservação da espécie, apresentam baixo potencial para o desenvolvimento de genótipos com características agronômicas superiores. A fim de criar e ampliar a variabilidade genética de fisális, os melhoristas tem empregado várias estratégias incluindo a indução de mutação, a duplicação cromossômica e a hibridação inter e intraespecífica. Além disso, a produção de linhagens duplo-haploides a partir da cultura de anterasin vitro vem demonstrando bons resultados para a seleção de híbridos. Os genótipos mutantes e/ou híbridos obtidos através dos métodos citados em associação com os de seleção genômica ampla podem gerar cultivares com características agronômicas superiores.

ABSTRACT: Physalisperuviana L. (physalis) has significant economic potential by virtue of the unique flavor of its fruit. However, the productivity of Brazilian plantations is low because of the limited number of varieties or cultivars available. The main obstacle in the selection of superior genotypes is the lack of information about genetic variability within- and between- populations and limited genetic basis that has likely resulted from evolutionary, domestication and selection processes of the natural or artificial populations. Physalis currently cultivated in Brazil is tetraploid, and such polyploidy may have led to the reproductive isolation of the species, preventing the occurrence of intraspecific hybridization. Moreover, cultivated populations derive from a common gene pool and have undergone a long process of domestication and selection carried out empirically by farmers. In Colombia and other Andean countries there are wild populations that exhibit genetic diversity which; although, fundamental for the conservation of the species, have low potential for the development of genotypes with superior agronomic traits. In order to create and expand the genetic variability of physalis, breeders have employed various strategies including induction of mutation, chromosome duplication, and interspecific and intraspecific hybridization. Furthermore, the production of double haploid lines from in vitro anther cultures has shown good results in the selection of hybrids. The mutant genotypes and/or hybrids obtained using these methods in association with those of wide genomic selection can generate cultivars with superior agronomic traits.

RESUMO: O uso da mecanização na cafeicultura tem se mostrado de suma importância na colheita do cafeeiro, reduzindo custo e tempo desta operação. Entretanto, a intensificação da colheita mecanizada, sem o controle dos riscos ocupacionais tem exposto trabalhadores aos níveis elevados de ruído ocupacional capazes de comprometer sua saúde auditiva. O objetivo do trabalho foi avaliar o nível de ruído ocupacional emitido por colhedoras automotrizes na colheita do cafeeiro, bem como os limites de exposição e nível de ação do operador e auxiliar. Para as avaliações foram utilizadas três colhedoras automotrizes: Case-IH® modelo COFFE EXPESS 200, com cabine; OXBO® modelo 9220, com cabine; KORVAN® modelo 9200, sem cabine. A coleta dos dados foi realizada utilizando dosímetro de ruído modelo DOS-700. Foi avaliado o nível de exposição ao ruído do operador e auxiliar das colhedoras. Foram realizadas cinco repetições, sendo cada repetição formada por duas horas de avaliações. Os dados obtidos foram comparados com o nível de ação e limite de exposição das normativas NHO 01 e NR 15. O nível de ação das normativas NHO 01 (82 dB) e NR 15 (80 dB) foram ultrapassados no operador e auxiliar nas três colhedoras avaliadas. Em relação ao limite de exposição (85 dB), o nível foi ultrapassado no operador das colhedoras KORVAN® e Case-IH® de acordo com a NHO 01. Na normativa NR 15, o limite de exposição ficou acima de 85 dB no operador da colhedora KORVAN®. No auxiliar todas as colhedoras emitiram níveis de ruídos acima de 85 dB tanto na normativa NHO 01 quanto na NR 15.

ABSTRACT: This study evaluated the level of occupational noise emitted by automotive harvesters during coffee harvest. For the evaluations, three self-propelled harvesters were used: Case-IH® model Coffee Express 200, with cabin; Korvan® model 9200, without cabin; and Oxbo® model 9220, with cabin. Data were collected using a noise dosimeter model DOS-700. Noise levels were assessed for the operator and assistant of each harvester. Five repetitions were performed for the operator and assistant, with each repetition consisting of 2 h of evaluation. Results obtained were compared with the action level and exposure limit of the Regulatory Norms (NR) 15 and Occupational Hygiene Norms (NHO) 01. The action levels of the NHO 01 (82 dB) and NR 15 (80 dB) regulations were exceeded for the operator and assistant in the three evaluated harvesters. Regarding the exposure limit (85 dB), the level was exceeded for the operator of the Korvan® and Case-IH® harvesters in accordance with NHO 01. In the NR 15 regulation, the exposure limit was > 85 dB for the operator of the Korvan® harvester. For the assistant, all harvesters emitted noise levels > 85 dB based on both the NHO 01 and NR 15 regulations.

ABSTRACT. Knowledge of the relationship between the equilibrium moisture content of the product and the air that involves it is essential to guarantee product quality and preserve its characteristics during storage. This trend can be studied by sorption isotherms. Thus, this study aimed to obtain desorption and adsorption isotherms of soybean grains to determine the mathematical model that best fits the experimental data and analyze the hysteresis phenomenon. Soybean grains with a moisture content of 21.95% (db) were used to verify the desorption process. The grains were dried until 3.50% (db) for the adsorption process. The static-gravimetric method was employed to determine the equilibrium moisture content of the grain at different temperatures (10, 20, 30, 40, and 50°C) and relative humidity levels (0.10 to 0.92%). Eight mathematical models were fitted to the experimental data. The modified Halsey model satisfactorily represented the desorption and adsorption phenomena of soybean grains. The equilibrium moisture content of soybean grains increased along with an increment in water activity. The increase in temperature led to a reduction in the equilibrium moisture content of soybean grains at a constant water activity. The equilibrium moisture content values obtained by desorption are higher than those obtained by adsorption, indicating the hysteresis phenomenon at the studied temperature range. The isotherms obtained for the desorption and adsorption process were classified as type III because of the high oil content in soybean grains.

Abstract Due to structural similarities and the possibility of connection between the two Aptian paleolakes in the Jatobá Basin and the Tucano Norte Sub-basin in North-eastern Brazil, the influence of the architecture of the crystalline basement under these lacustrine sedimentary rocks was analysed using gravimetric data near the faulted edges of the basins where the paleolakes are located. The Negra (Jatobá Basin) and Tonã (Tucano Norte Sub-basin) Hills are mainly sedimentary deposits of Aptian age and are linked to the post-rift I tectonic sequence. Aiming at the study of reservoirs analogous to pre-salt reservoirs, the gravimetric data were processed and interpreted to define the structural framework of the basin regions around these hills. Depth maps and density models were generated that could be analysed from various 3D perspectives, and the behaviour of the crystalline basement below these sedimentary sequences was investigated. In addition to the identification of horsts and semi-grabens that influenced the current relief pattern, the modelling showed that the Aptian paleolake sedimentary rocks of the Negra Hill are in the Ibimirim Low, which is approximately 2,900 m deep, while in the Tonã Hill, the sedimentary rocks are in the Salgado do Melão Low, which is approximately 5,100 m deep.
