Abstract Despite being little explored for petroporphyrins recovery from oils and bituminous shales, adsorption and desorption processes can be feasible alternatives to obtain a similar synthetic material, and to characterize their original organic materials. Experimental designs were used to analyze the effects of qualitative (e.g., type of adsorbent, solvent, and diluent) and quantitative (e.g., temperature and solid/liquid ratio) variables on the adsorptive and desorptive performance regarding nickel octaethylporphyrin (Ni-OEP) removal using carbon-based adsorbents. The evaluation variables, adsorption capacity (qe) and desorption percentage (%desorption) were optimized by means of the Differential Evolution algorithm. The most efficient adsorbent for removing/recovery Ni-OEP was activated-carbon coconut shell, in which dispersive π-π type and acid-base interactions were likely formed. The highest values of qe and %desorption were obtained using toluene as solvent, chloroform as diluent, 293 K as temperature, and 0.5 mg.mL-1 as solid/liquid ratio for adsorption, and a higher temperature (323 K) and lower solid/liquid ratio (0.2 mg.mL-1) for desorption. The optimization process resulted in qe of 6.91 mg.g-1 and %desorption of 35.2%. In the adsorption-desorption cycles, approximately 77% of the adsorbed porphyrins were recovered. The results demonstrated the potential of carbon-based materials as adsorbent materials for obtaining porphyrin compounds from oils and bituminous shales. shales material e.g., eg e g (e.g. solvent diluent solidliquid solid liquid NiOEP Ni OEP (Ni-OEP carbonbased carbon based adsorbents (qe (%desorption algorithm removingrecovery removing activatedcarbon activated shell ππ π acidbase acid base formed 29 05 0 5 0. mg.mL1 mgmL1 mgmL mg.mL 1 mg mL mg.mL- 323 (32 0.2 02 2 (0. 691 6 91 6.9 mg.g1 mgg1 mgg mg.g mg.g- 352 35 35.2% adsorptiondesorption cycles 77 recovered e.g. (e.g mL1 32 (3 (0 69 9 6. g1 3 35.2 7 e.g ( 35.

RESUMO Objetivo: Estimar a prevalência de Infecções Sexualmente Transmissíveis (IST) em imigrantes e refugiados residentes na região metropolitana de Goiânia, Goiás. Método: Trata-se de um estudo transversal e analítico. A coleta de dados foi realizada no período de julho de 2019 a janeiro de 2020 e integraram a amostra 308 imigrantes e refugiados.

RESUMO O ácido naftênico 1,4-ciclohexanodicarboxílico é um dos principais contaminantes do petróleo e das águas residuais de petroquímicas, podendo causar consideráveis danos às operações industriais bem como ao meio ambiente, devido ao seu caráter corrosivo e sua toxicidade. Uma operação que pode ser realizada para a separação deste contaminante é a adsorção. Nesse sentido, o presente trabalho teve como finalidade avaliar a capacidade e eficiência adsortivas do carvão ativado de osso de boi em sistemas em batelada e em leito fixo para a remoção do ácido 1,4-ciclohexanodicarboxílico. Inicialmente, os carvões ativados brutos e tratados com NaOH foram utilizados no sistema em batelada (pH = 3,2; m = 50 mg). Os valores dos dados cinéticos e os de equilíbrio indicaram o carvão tratado como um melhor adsorvente para o ácido naftênico, com quantidades retidas experimentais no equilíbrio de 380 mg.g−1. O carvão ativado tratado foi escolhido para os ensaios em leito fixo e, inicialmente, a vazão ótima de operação foi obtida. Os parâmetros de transferência de massa indicaram que os efeitos difusionais no leito foram minimizados em 2 mL.min− 1. A isoterma dinâmica foi obtida e avaliada como irreversível a partir dos balanços de massa nas curvas de ruptura, com altos valores de quantidades retidas (316,6 mg.g−1). Foram observados diferentes mecanismos de transferência de massa nos sistemas em batelada e contínuo. No entanto, os valores das capacidades de adsorção no equilíbrio foram semelhantes. Com isso, o carvão ativado de osso de boi foi favorável na remoção do ácido 1,4-ciclohexanodicarboxílico.

ABSTRACT The 1,4-cyclohexanedicarboxylic naphthenic acid is one of the main contaminants of petroleum and petrochemical wastewater. It can cause considerable damage to industrial operations as well as to the environment, due to its corrosive character and toxicity. An operation that can be performed to separate this contaminant is adsorption. Hence, the present paper aimed to evaluate the adsorptive capacity and efficiency of bovine bone activated charcoal in batch and fixed bed systems for the 1,4-cyclohexanedicarboxylic acid removal. Initially, crude and NaOH-treated activated charcoal was used in a batch system (pH = 3.2; m = 50 mg). The kinetic and equilibrium data indicated the treated charcoal as a better adsorbent for naphthenic acid, with experimental amounts retained in the equilibrium of 380 mg.g−1. Treated activated charcoal was chosen for the fixed bed assays and, at first, the optimum flow of operation was obtained. Mass transfer parameters indicated that the diffusional effects on the bed were minimized by 2 mL.min−1. The dynamic isotherm was obtained from the mass balances in the rupture curves and was evaluated as irreversible, with high values of retained acid (316.6 mg.g−1). Different mass transfer mechanisms were observed in batch and continuous systems. However, the values of adsorption capacities in the equilibrium were similar. Thus, the bovine bone activated charcoal was favorable for the 1,4-cyclohexanedicarboxylic acid removal.

Abstract Objective To investigate the association between asthma and sleep duration in participants of the Study of Cardiovascular Risks in Adolescents. Materials and methods Cross-sectional, national, school-based study, involving adolescents aged 12-17 years. In the period between 2013−14, data from 59,442 participants were analyzed. Bivariate analysis between current asthma and short sleep duration, defined as < 7 h/night, was performed separately with the other variables analyzed: sex, age group, type of school, weight categories, and common mental disorders. Then, different generalized linear models with Poisson family and logarithmic link functions were used to assess the independence of potential confounding covariates associated with both asthma and short sleep duration in the previous analysis. Crude and adjusted prevalence ratios and respective 95% confidence intervals were calculated, and a value of p < 0.05 was considered significant for all analyses performed. Results Prevalence of current asthma was 13.4%, being significantly higher among students with short sleep duration (PR: 1.17; 95% CI: 1.01-1.35; p = 0.034). This remained significant even after adjusting for the other study covariates. Conclusion There was a positive association between the prevalence of current asthma and short sleep duration among Brazilian adolescents. Considering the high prevalence and morbidity of the disease in this age group, the promotion of sleep hygiene should be considered as a possible health strategy aimed at contributing to better control of asthma in this population.
