25. Efficiency of the anaerobic baffled reactor followed by anaerobic filter in the removal of nutrients and pathogenic organisms in fish processing effluents
RESUMO A atividade de aquicultura apresentou elevado crescimento, juntamente com o aumento do consumo de proteína animal proveniente desse setor. As indústrias de processamento facilitam o preparo do pescado ao consumidor, todavia geram grandes volumes de efluentes de alto potencial poluidor. A legislação ambiental estabelece normas para o lançamento de

26. Employment of chitosan in the removal of pollutants in fish processing effluents
RESUMO O crescimento expressivo do setor industrial nas últimas décadas acarretou o aumento do volume de resíduos, que, se não forem destinados adequadamente, poderão causar sérios problemas ambientais. No contexto da aquacultura, efluentes líquidos com um alto teor orgânico são gerados em grandes quantidades nas indústrias de processamento de pesc

27. Tin speciation in the blood plasma of workers occupationally exposed in a cassiterite ore processing industry
RESUMO A mineração é uma atividade de alto risco devido aos seus processos perigosos. O estanho (Sn) é obtido do minério de cassiterita e as atividades da mineração expõem os trabalhadores ao metal. A exposição crônica ao Sn pode causar pneumoconiose, gastrointestinal e hematológica entre outros efeitos. Este trabalho avaliou a exposição de tra

28. Physical-chemical characterization, bioactive compounds, and antioxidant activity of pulp and peel of the Jamelão
ABSTRACT The high production of jamelão (Syzygium cumini) during harvest and the lack of information about it emphasize the development of new processing technologies for this fruit since it has been proven that its different parts have functional properties. The objectives of this work were to evaluate the physical-chemical characteristics and to determine

29. Water footprint of Arabica coffee from “Matas de Minas” under shade management
ABSTRACT Studies related to climate change and agricultural value chains have in common the growing concern on conserving water resources. Thus, the concept of the water footprint stands out, which measures the amount of water (in volume) necessary to produce a unit (in mass) of a given product. Among Brazilian agricultural activities, coffee farming emerges

30. Smartphone-Based Screening for Cardiovascular Diseases: A Trend?
Abstract Cardiovascular diseases are the leading cause of death in the world. People living in vulnerable and poor places such as slums, rural areas and remote locations have difficulty in accessing medical care and diagnostic tests. In addition, given the COVID-19 pandemic, we are witnessing an increase in the use of telemedicine and non-invasive tools for

31. Valorization of Hesperidin from Citrus Residues: Evaluation of Microwave-Assisted Synthesis of Hesperidin-Mg Complex and Their Insecticidal Activity
The aim of the current study was the valorization of hesperidin, the dominant flavonoid in citrus processing waste, by microwave-assisted synthesis of hesperidin-Mg complex, improving its antioxidant activity and insecticidal potential. Here we show, for the first time, that microwave-assisted synthesis of [Mg(hesp)2(phen)]OAc (1) (hesp: hesperidin, phen: ph

32. Rhinological Status of Patients with Nasolacrimal Duct Obstruction
Abstract Introduction Studying the state of the nasal cavity and its sinuses and the morphometric parameters of the inferior nasal conchae, as well as a comparative analysis of obtained values in patients with primary (PANDO) and secondary acquired nasolacrimal duct obstruction (SALDO), is relevant. Objective To study the rhinological status of patients wi

33. The Relationship between Contralateral Suppression of Transient Evoked Otoacoustic Emission and Unmasking of Speech Evoked Auditory Brainstem Response
Abstract Introduction Several studies have shown that efferent pathways of the auditory system improve perception of speech-in-noise. But, the majority of investigations assessing the role of efferent pathways on speech perception have used contralateral suppression of otoacoustic emissions as a measure of efferent activity. By studying the effect of effere

34. Impressions of the chronic 900-MHz electromagnetic field in the prenatal period on Purkinje cells in male rat pup cerebella: is it worth mentioning?
SUMMARY OBJECTIVE: The aim of this study was to examine the changes on the Purkinje cells in the cerebella of male rat pups born to pregnant dams that were exposed to an electromagnetic field in the prenatal period. METHODS: The first stage of the study involved 12 Sprague-Dawley rats, 6 male and 6 female, weighing between 180 and 250 g. The female rats in

35. Processing speed impairment in chronic inflammatory demyelinating polyneuropathy patients: a cross-sectional study
Resumo Antecedentes Faltam evidências de envolvimento cognitivo na polineuropatia inflamatória desmielinizante crônica (PIDC), e há poucos e controversos estudos que tratam do envolvimento cerebral e do sistema nervoso central (SNC). O Teste dos Cinco Dígitos (Five Digit Test, FDT, em inglês) avalia a velocidade de processamento (VP) e as funções ex

36. Processamento de catalisadores gastos de unidade de hidrodessulfurização profunda (ultra-deep HDS)
PROCESSING OF SPENT ULTRA-DEEP HYDRODESULFURIZATION CATALYSTS. This work discusses the recycling of spent NiMo/Al2O3 catalysts from ultra-deep hydrodesulfurization (HDS) units. They contain a refractory coke and fouling elements from the processed feedstocks. Samples were preoxidized (600 ºC) for 12 h using a very slow heating rate to eliminate coke and vol
