Abstract In the county of Pedra Lavrada - PB, various mineral occurrences of pegmatite are observed with prominence at Alto Dois Irmãos - PB, where quartz, feldspar and mica are mined. The understanding of mineral constituents is fundamental to define their industrial employment and to implement improvements in the beneficiation process. The proposal of this research is the detailed characterization and proof of that part of the ore (quartz) considered waste, presenting low poisoning (Fe2O3) and high silica (SiO2) content, to enable its industrial use. Besides that, to minimize the environmental impact through the reuse of this waste, and to determine the correct utilization of the milling equipment. For the pegmatite characterization, done were density determination tests, mineralogical identification by X-ray diffraction (XRD), chemical analysis by fluorescents X-rays and morphological analysis by scanning electron microscopy (SEM/EDS). Then tests were done for the Work Index (WI) calculous and consequently the empirical determination of the dimensions (LxD) of the pebble mill. The sterile presented a medium density of 2.66g/cm³, majority chemical composition of silicon and oxygen and quartz as the main mineralogical stage, indicating that this material has high purity. The. The Work Index (WI) was 15.9 kwh/t showing that this material can be considered resistant to breaking in the grinding process. The necessary energy to the milling was defined in 11.52 kwh/st, that corresponds to 57.28 HP. This power allowed the mill selection with diammeter and length of 1.83m, that provides the production maximization and the energy saving.

Abstract This article evaluated the effect of soybean cultivation on the level of socioeconomic development and economic growth of the Brazilian AMC's (Minimum Comparable Areas), between the years 1991 and 2010. For this, the models Differences in Differences with Propensity Score were estimated. (DDM), evaluating the impact of “being a soybean producer” on the Gross Domestic Product (GDP) per capita and on the dimensions of the Municipal Human Development Index (HDI-M). The results showed that soybean production did not impact the global HDI-M, with a positive effect only on the HDI - knowledge. In the case of the longevity dimension, a negative impact was identified, possibly due to the intensive use of pesticides, which affects the health of rural workers and residents of nearby locations. In the case of economic growth, the effect was positive, inferring that “being a soy-producing AMC” tends, on average, to intensify GDP per capita.

Resumo Este artigo avalia o efeito do cultivo da soja sobre o nível de desenvolvimento socioeconômico e do crescimento econômico das AMC’s (Áreas Mínimas Comparáveis) brasileiras, entre os anos de 1991 e 2010. Para isso, foram estimados os modelos Diferenças em Diferenças com Escore de Propensão (DDM), avaliando o impacto de ser produtor de soja no Produto Interno Bruto (PIB) per capita e nas dimensões do Índice de Desenvolvimento Humano Municipal (IDH-M). Os resultados demonstraram que a produção de soja não impactou o IDH-M global, apresentando efeito positivo apenas no IDHM-conhecimento. No caso da dimensão longevidade, identificou-se um impacto negativo, possivelmente em decorrência do uso intensivo de agrotóxicos, que afeta a saúde dos trabalhadores rurais e moradores de localidades próximas. No caso do crescimento econômico, o efeito foi positivo, inferindo que “ser uma AMC produtora de soja” tende, na média, a intensificar o PIB per capita.

ABSTRACT BACKGROUND: Precisely determining the aspects related to an instrument's validity and reliability measures allows for greater assurance of the quality of the results. OBJECTIVES: To analyze the psychometric properties of The Providers Survey in the Brazilian context of mental health services. DESIGN AND SETTING: The instrument validation study was conducted in Montes Claros, Minas Gerais, Brazil. METHODS: The validation study was conducted using the Consensus-based Standards for the Selection of Health Measurement Instruments checklist to analyze its validity and reliability. RESULTS: A committee of expert judges performed content validation after which the Content Validity Index was calculated. Construct validation took place through Exploratory Factor Analysis using the Kaiser-Meyer-Olkin Test criterion and Bartlett's Sphericity Test. Reliability was verified using test-retest reliability. The significance level adopted for the statistical tests was 5% (P < 0.05). The final instrument comprised 54 questions. The Content Validity Index was 97%. Exploratory Factor Analysis identified a Kaiser-Meyer-Olkin index of 0.901 and Bartlett's Sphericity Test with P < 0.001. We obtained a Cronbach's alpha coefficient of 0.95 and an intraclass correlation coefficient of 0.849. CONCLUSIONS: The Providers Survey, translated and adapted into Portuguese, was named the Work Assessment Instrument for the Recovery of Mental Health. It presented adequate psychometric properties for evaluating work-related practices for the recovery of psychosocial care network users.

ABSTRACT Harvest delay can alter the physiological and sanitary quality of sorghum seeds due to the longer exposure time of seeds to adverse environmental conditions in the field. In this study, we investigated the impact of delayed Sorghum sp. harvest on the physiological and sanitary quality of seeds in four hybrids grown in the tropical soil of the Brazilian Cerrado region. Plants from four Sorghum sp. hybrids (IPA SUDAN 4202, BRS 658, BRS 810, and BRS 373) were grown and submitted to four seed harvest periods (0, 7, 14, and 21 days after stage 9 - seed physiological maturity). The treatments were arranged in a completely randomized block design in a 4 × 4 factorial, with four replicates. At each harvest period, the thousand-seed weight, water content, first count of the germination test, germination, seedling emergence, emergence speed index, seedling dry matter, accelerated aging, electrical conductivity, and sanitary quality of seeds were determined. Seeds of higher physiological and sanitary quality of the IPA SUDAN 4202 and BRS 658 sorghum hybrids can be obtained when the harvest is carried out up to 7 days after the physiological maturity stage. However, the delay in seed harvesting at 14 and 21 days after physiological maturity results in a higher incidence of Colletotrichum sp., Curvularia sp., Rhizoctonia sp., and Alternaria sp. on the seeds of these hybrids. Delaying the harvest of sorghum seeds from 7 days after the physiological maturity stage compromises seed vigor and viability and increases the incidence of pathogens.

Resumo Introdução: A pancreatite da goteira (PG) constitui uma forma de pancreatite crónica segmentar, que afeta a área da goteira pancreatoduodenal, sendo frequentemente subdiagnosticada. O mecanismo fisiopatológico principal parece ser a obstrução ao fluxo da papila minor relacionada com o consumo de álcool. Esta patologia ocorre mais frequentemente em homens entre a 4a e 5a décadas de vida. A maioria dos doentes apresenta sintomas como náuseas e vómitos pós-prandiais, perda ponderal e dor abdominal. Apesar do desenvolvimento atual dos métodos radiológicos e endoscópicos, a distinção entre PG e neoplasia pancreática constitui um desafio diagnóstico e a avaliação histológica pode ser necessária. Se for possível obter o diagnóstico sem intervenção cirúrgica, o tratamento pode ser conservador na ausência de complica-ções agudas e crónicas. Apresentação do caso: Apresentamos 2 casos clínicos que demonstram a abordagem diagnóstica e a gestão de decisões terapêuticas nesta entidade. Discussão/Conclusão: A PG é uma entidade clínica que oferece com diagnóstico e terapêutica desafiantes. Apesar da importância crucial dos exames imagiológicos no diagnóstico e seguimento, a incapacidade de excluir um processo maligno torna necessária a intervenção cirúrgica numa parte significativa dos casos.

Abstract Introduction: Groove pancreatitis (GP) is a type of chronic segmental pancreatitis that affects the pancreatoduodenal groove area, and it is often misdiagnosed. Outflow obstruction of the minor papilla associated with alcohol consumption seems to be the main pathophysiological mechanism, and it affects mainly middle-aged males. Symptoms include nausea and postprandial vomiting from gastric outlet obstruction, weight loss, and abdominal pain. Despite modern advances, such as radiological and endoscopic methods, distinction between GP and pancreatic cancer remains a challenge, and histological examination is sometimes necessary. When a diagnosis can be obtained without a surgical specimen, management can be conservative in the absence of acute or chronic complications. Case Presentation: The authors present 2 clinical cases which portray the diagnostic workup and management decisions of this entity. Discussion/Conclusion: GP is a clinical entity, offering diagnostic and therapeutic challenges. Imaging exams are crucial in the diagnosis and follow-up, but surgery may be necessary in a significant number of cases due to the incapacity to rule out malignancy.

ABSTRACT The aim of this study was to investigate the association between sociodemographic characteristics, related to environmental and occupational exposure and self-report of intoxication in patients diagnosed with cancer in Mato Grosso, Brazil. This is a cross-sectional study, with 998 cancer patients seen at referral hospitals in the state. The dependent variable was obtained from the self-report of some intoxication symptom in the last 5 years and whether or not the intoxication was caused by work/occupation. The association between sociodemographic characteristics, related to intoxication and environmental and occupational exposure and self-report of intoxication was assessed by Fisher’s exact test. Of all respondents, 7.4% (95%CI: 6.0; 9.2) reported intoxication, and 2.3% (95%CI: 1.5; 3.4) were work-related. Factors associated with self-reported work-related intoxication were being male, having less than 4 years of education, headache, intoxication by agricultural pesticides, by respiratory route and having worked with pesticides, asbestos, heavy metals and industrial dust. It was concluded that individuals with higher occupational exposure to pesticides and other chemicals reported higher occurrence of poisoning due to work.

RESUMO O objetivo deste estudo foi investigar a associação entre características sociodemográficas relacionadas à exposição ambiental e ocupacional e o autorrelato de intoxicação de pacientes com diagnóstico de câncer em Mato Grosso, Brasil. Trata-se de um estudo transversal, com 998 pacientes com câncer atendidos em hospitais de referência do estado. A variável dependente foi obtida a partir do autorrelato de algum sintoma de intoxicação nos últimos 5 anos e se a intoxicação foi decorrente ou não do trabalho/ocupação. A associação entre características sociodemográficas relacionadas à intoxicação e à exposição ambiental e ocupacional e o autorrelato de intoxicação foi avaliada pelo teste exato de Fisher. Do total de entrevistados, 7,4% (IC95%: 6,0; 9,2) referiram intoxicação, sendo 2,3% dos casos (IC95%: 1,5; 3,4) decorrentes do trabalho. Os fatores associados ao autorrelato de intoxicação decorrente do trabalho foram ser do sexo masculino, ter escolaridade menor que 4 anos, sintoma de dor de cabeça, intoxicação por agrotóxico agrícola, por via respiratória e ter trabalhado com agrotóxicos, amianto, metais pesados e poeira industrial. Conclui-se que os indivíduos com maior exposição ocupacional aos agrotóxicos e a outros produtos químicos referiram maior ocorrência de intoxicações decorrentes do trabalho.

Resumen La prevención de lavado de dinero es un tema que ha tomado importancia en los últimos años en el sector financiero, debido a que dicho sector resulta vulnerable a ser utilizado para perpetrar este delito. En este trabajo, se analiza la mejor decisión por parte de las instituciones de banca múltiple respecto a bloquear o no bloquear las tarjetas de crédito ante posibles escenarios de lavado de dinero por parte de sus tarjetahabientes. Con base en un análisis de información incompleta, se deducen instrumentos para que la institución decida bloquear o no una cuenta que presente operaciones inusuales; con la finalidad de evitar pérdidas financieras y un daño en su reputación por relacionarse con tarjetahabientes que lavan dinero. El factor diferenciador de este trabajo consiste en la construcción de señales mediante vectores de pesos asignados a los factores de lavado de dinero, que pueden servir como indicadores o agravantes ante posibles operaciones inusuales de los tarjetahabientes.

Abstract In recent years, the prevention of money laundering has gained importance in the financial sector because this sector is being used to perpetrate this crime. This paper analyzes the best decision by banking institutions regarding the blocking or not of credit cards in the face of possible money laundering scenarios by their cardholders. Based on an analysis of incomplete information, we deduce instruments that help the institution decide to block or not, an account that presents unusual operations; to avoid financial losses and damage to their reputation from being involved with cardholders who launder money. The differentiating factor of this work consists in the construction of signals through vectors of weights assigned to the money laundering factors, which can serve as indicators or aggravating factors in possible unusual operations by cardholders.

Abstract: En Es Pt

Large-scale assessments play a central role in shaping public policies in Basic Education across various countries, exerting both symbolic and material effects on educational institutions and the teaching profession. In Brazil, alongside the Basic Education Assessment System, numerous states and municipalities have developed their own assessment models, resulting in a continuous presence of external audits in the school routine. This study examines how teachers in public education systems interpret these assessment processes, with a particular focus on their perceptions regarding the potential differential value placed on specific subjects prioritized in standardized exams. The data used in this analysis are derived from a survey conducted in four states in the Northeast region of Brazil (Bahia, Paraíba, Pernambuco, and Rio Grande do Norte). The findings indicate that teachers perceive an overemphasis on Portuguese and Mathematics, with this perception being more pronounced among teachers in systems that enforce high-stakes policies.

Las evaluaciones a gran escala desempeñan un papel central en la configuración de las políticas públicas en Educación Básica en una variedad de países, con efectos simbólicos y materiales en las instituciones escolares y la categoría docente. En Brasil, además del Sistema de Evaluación de la Educación Básica, varias províncias y municipalidades han desarrollado sus propios modelos de evaluación, de modo que la vida escolar está permanentemente influenciada por auditorías externas. En este artículo buscamos analizar cómo los docentes de escuelas públicas interpretan estos procesos, con énfasis en sus percepciones sobre una posible valoración diferenciada de las materias priorizadas en los exámenes estandarizados. Los datos utilizados se derivan de survey realizado en cuatro estados de la región Nordeste de Brasil (Bahia, Paraíba, Pernambuco y Rio Grande do Norte). Se constató que la percepción de los docentes es de uma sobrevalorización de Portugués y Matemática, siendo este índice más elevado entre los docentes de redes que imponen políticas de flerte responsabilización (high stake).

Abstract Evaluate the shaping ability and preparation time using a pediatric motor-driven rotary instrumentation compared to other systems in resin prototypes of primary molars. Methods: Thirty specimens were scanned in micro-CT and divided into three groups according to the instrumentation type: pediatric motor-driven Sequence baby File (SBF); conventional motor-driven (Sequence Rotary File - SRF); manual K file. Instrumentation time was timed. After preparation, the specimens were scanned again. The pre- and post-instrumentation images were superimposed to measure the amount of root canal deviation and the resin remnant thickness. ANOVA followed by the Tukey test analyzed the comparisons between groups (p<0.05). Results: No statistically significant differences occurred in root canal deviation among groups (p>0.05). There were statistically significant differences in the comparison among root thirds (p<0.001) but without significant differences in the interaction group vs. root third (p>0.05). Both motor-driven instrumentations showed statistically greater weariness than manual instrumentation (p<0.001), without significant significant differences between SBF and SRF. Motor-driven instrumentation had a shorter working time than manual instrumentation (p<0.001). Conclusion: Pediatric motor-driven instrumentation demonstrated good outcomes in relation to root canal deviation and amount of remnant structure, with shorter instrumentation time. SBF can be a suitable alternative for endodontic instrumentation in primary molars.

Resumo Objetivo: Avaliar os resultados da instrumentação endodôntica e o tempo de preparo de lima odontopediátrica ativada por motor (Sequence Baby File- SBF) em canais de molares decíduos prototipados. Métodos: Trinta espécimes foram escaneados em micro-CT e divididos em três grupos de acordo com o tipo de instrumentação: mecanizada odontopediátrica (SBF); mecanizada convencional; lima K manual. O tempo de instrumentação foi cronometrado. Após o preparo, os espécimes foram escaneados novamente. As imagens pré e pós-instrumentação foram sobrepostas e a quantidade de desvio do canal radicular e a espessura de resina remanescente foram mensurados. Para as análises de comparações entre os grupos foram realizados teste ANOVA seguido do teste de Tukey (p<0,05). Resultados: Não ocorreram diferenças estatisticamente significativas entre os grupos no desvio do canal radicular (p>0,05). Houve diferenças estatisticamente significativas na comparação entre terços radiculares (p<0,001), mas sem diferenças significativas na interação grupo vs. terço radicular (p>0,05). A instrumentação mecanizada apresentou desgaste estatisticamente maior do que a instrumentação manual (p<0,001), sem diferenças estatísticas entre a SBF e a lima mecanizada convencional. A instrumentação mecanizada teve menor tempo de trabalho quando comparado a instrumentação manual (p<0,001). Conclusão: A instrumentação mecanizada odontopediátrica demonstrou bons resultados em relação ao desvio do canal radicular e quantidade de estrutura remanescente, com menor tempo de instrumentação. A SBF pode ser uma alternativa adequada para a instrumentação endodôntica em molares decíduos.
