title: Modeling effluent plumes between Praia Grande and Peruíbe, São Paulo State’s shore, Brazil

description: ABSTRACT This study’s goal was to monitor the dispersion of effluent plumes from the Praia Grande’s submarine outfalls and from the Itanhaém River by processing the Delft3D model (hydrodynamic and water quality modules) and the Visual Plumes model (UM3 module). The near field modeling indicated that wind-driven currents were more efficient than tidal currents in the initial dilution of the outfalls’ plumes; and the far field modeling, qualitatively validated, demonstrated that the potential pollutants’ concentrations in all the simulated plumes don’t exceed the maximum limits established by the National Environmental Council when these plumes reach the study region’s beaches.

title: Bacaba powder produced in spouted bed: an alternative source of bioactive compounds and energy food product

description: Abstract This study evaluated Bacaba powder produced in a spouted bed as a source of bioactive compounds and high energy value. The conditions influencing the drying process parameters (yield, moisture level, phenolic and anthocyanin retention) as well as simultaneous optimization (optimal conditions) of production were also considered. Drying was most efficient at 75 °C using maltodextrin concentrations above 20.0% (w/w). Higher anthocyanin retention (92.52%) at 65 °C (p = 0.0003), and a maltodextrin concentration of 20.0% (w/w) resulted in high retention of phenolics (95.38%). Accordingly, the operations tested under the desirability function (68 °C, maltodextrin concentration of 21.7% w/w, and air velocity of 1.3 × minimum spouting velocity (Vjm) m s-1) resulted in a process yield of 55.04% and the dry basis (d.b.) composition results were: total phenolics (376.43 mg GAE 100 g-1), energetic value (612.64 kcal 100 g-1), lipids (47.74 g 100 g-1), carbohydrates (27.79 g 100 g-1), protein (15.10 g 100 g-1), and dietetic fiber (8.45 g 100 g-1). The high solubility (92%), flowability (14%), energy, and bioactive characteristics of Bacaba powder suggest the potential for many applications, such as development of dietary supplements, high-energy drinks, milk-based and instant products, and bakery products.

title: Sarcopenia and sarcopenic obesity as prognostic predictors in hospitalized elderly patients with acute myocardial infarction

description: ABSTRACT Objective: To investigate the potential value of sarcopenia and sarcopenic obesity as prognostic predictors in hospitalized elderly patients with acute myocardial infarction. Methods: A cross-sectional study based on data collected from elderly patients with acute myocardial infarction, admitted to a public hospital located in the Northeastern region of Brazil, from April to July 2015. The diagnosis of sarcopenia was based on muscle mass, muscle strength and physical performance measurements. Cardiovascular risk and prognostic markers, such as troponin and creatine kynase MB isoenzyme values, acute myocardial infarction classification according to ST segment elevation, and thrombolysis in myocardial infarction score were used. Results: The sample comprised 99 patients with mean age of 71.6 (±7.4) years. Prevalence of sarcopenia and sarcopenic obesity was 64.6% and 35.4%, respectively. Sarcopenia was more prevalent among males (p=0.017) aged &gt;80 years (p=0.008). Thrombolysis in myocardial infarction was the only marker of cardiovascular risk significantly associated with sarcopenia (p=0.002). Conclusion: Prevalence of sarcopenia was high and associated with thrombolysis in myocardial infarction risk score. Sarcopenic obesity affected approximately one-third of patients and was not associated with any of the prognostic predictors.

title: Osteogenesis imperfecta in Brazilian patients

description: Abstract Osteogenesis Imperfecta (OI) is a heterogeneous genetic disorder characterized by bone fragility and fracture. Mutations in 20 distinct genes can cause OI, and therefore, the genetic diagnosis of OI is frequently difficult to obtain because of the great number of genes that can be related with this disease. Studies that report the most frequently mutated genes in OI patients can help to improve molecular strategies for diagnosis of the disease. In order to characterize the mutation profile of OI in Brazilian patients, we analyzed 30 unrelated patients through SSCP screening, NGS gene panel, and/or Sanger sequencing for the 11 most frequently mutated genes in the database of mutations, including COL1A1, COL1A2, P3H1, CRTAP, PPIB, SERPINH1, SERPINF1, FKBP10, SP7, WNT1 and IFITM5. Disease-causing variants were identified in COL1A1, COL1A2, FKBP10, P3H1, and IFITM5. A total of 28 distinct mutations were identified, including seven novel changes. Our data show that the analysis of these five genes is able to detect at least 95% of causative mutations in OI disorder from Brazilian population. However, it has to be taken into considerations that distinct populations can have different frequencies of disease-causing variants. Hence, it is important to replicate this study in other groups.

title: El análisis de imágenes como herramienta de monitoreo en la deshidratación de rodajas de banana

description: Resumen El objetivo de este trabajo fue evaluar los cambios morfométricos, fractales y de color durante la deshidratación de rodajas de banana mediante el uso de análisis de imágenes y la relación de estos parámetros con la cinética de secado. El secado convectivo se realizó entre 75 °C y 134 °C a una velocidad de aire de 0,65 m s-1. Los resultados mostraron que las imágenes tomadas proporcionaron información cuantitativa de los cambios morfométricos (reducción de área y circularidad, y aumentos del perímetro) por efecto de los tratamientos térmicos. El análisis de la textura fractal detectó cambios en la intensidad de los pixeles, indicando que las superficies resultaron más complejas e irregulares a medida que disminuyó el contenido de humedad del producto. La dimensión fractal de contorno (DFcont) aumentó con el tiempo de secado. En relación al color del producto seco, los parámetros a* y b* aumentaron, mientras que la Luminosidad (L*) disminuyó, lo cual está asociado al oscurecimiento de las rodajas e influenciado por el aumento de la temperatura. Las micrografías determinaron la presencia de poros que fueron aumentando en cantidad cuando incrementó la temperatura. Los resultados muestran que el análisis de imágenes puede ser empleado como herramienta de monitoreo debido a su versatilidad, bajo costo, rapidez de respuesta, además de no ser una técnica destructiva.

title: Generation, treatment and final disposal of the waste of water treatment stations in the state of Pernambuco, Brazil

description: ABSTRACT This article deals with the generation, quantification and final disposal of the sludge generated at existing Water Treatment Plants (WTPs), operating in the state of Pernambuco. The research was carried out in the period between January 2015 and December 2016 by the collection, systematization and interpretation of data that showed 246 WTPs that generate residues, of which 69 in decanters and filters, 176 only in the filters and one in the desalination system. The largest number of conventional WTPs is in the metropolitan region of Recife and the highest production of sludge was observed in the Capibaribe river basin, which receives a load of between 50 and 50,000 kg / (m3day). It was verified that approximately 75% of the state’s WTPs discard their residues in water bodies and 22% in the soil, without any kind of treatment. Only 3% perform the degassing process, yet discarding the solid mass in the soil, without any control at the final disposal of the same.

title: Energy and budget balances for sweet potato-based ethanol production

description: Abstract: The objective of this work was to assess the viability of sweet potato (Ipomoea batatas) for ethanol production, as well as to estimate the energy and budget balances for the crop. Data from the agricultural and industrial production phases were evaluated. Those from the agricultural phase were estimated from a field experiment and used for comparison of sweet potato genotypes. Those from the industrial phase were estimated based on the literature on the fossil fuel energy and electricity consumed in the ethanol production process. With average yields of 35 Mg ha-1 roots and 12 Mg ha-1 dry stems, the output/input ratios were 6.64 and 1.93 for the energy and budget balances, respectively. For yields of 50 and 80 Mg ha-1 roots (17 and 27 Mg ha-1 dry stems, respectively), the indexes for energy balance were 7.16 and 7.68, respectively, and those for energy budget were 2.76 and 4.42. The obtained results confirm the great aptitude of the sweet potato crop for biofuel production.

title: Influence of the geotextile blanket and sludge height in anaerobic sludge dewatering using drainage bed

description: ABSTRACT Sewage Treatment Plants generate sewage sludge, which has approximately 95% of water and requires a proper disposal. Thus, dewatering is fundamental in sludge’s management since it promotes volume reduction of the residue. The drainage bed (DB) is a natural system, without the use of energy and chemicals, with prosperous results for the dewatering of sludge from Water Treatment Plants. In this sense, this research aimed to evaluate sewage sludge’s dewatering from Upflow Anaerobic Sludge Blanket (UASB). The analysis was performed through nine tests in DB models from laboratory scale with a bottom area of 31 × 31 cm. The tests were performed with three different geotextiles blankets: HaTe 55/55; 80/80 and 105/105 DW and three heights of applied crude sludge: 10, 15 and 20 cm. In the tests, the crude sludge’s initial solid content was measured. Then, at predetermined time intervals were measured: drainage flow, drained volume, apparent color, turbidity, pH and drained liquid’s conductivity. The tests with the HaTe 55/55 geotextile blanket obtained the best performance, with final reduction of the sludge volume above 65%, independent of the height of the sludge applied. The color and turbidity results of the drained liquid for the HaTe 55/55 geotextile blanket showed a tendency to improve quality with the increase of the sludge height, a fact not observed for the other geotextiles blankets.

title: Functional capacity and social support to people affected by cerebrovascular accident

description: ABSTRACT Objective: To investigate the functional capacity and its relationship with the level of social support to people affected by cerebrovascular accident. Methods: Cross-sectional and quantitative research, conducted with 108 individuals with sequelae of cerebrovascular accident in João Pessoa/PB. Data were collected through interviews, using a sociodemographic instrument – the Barthel Index and the Social Support Scale. Results: We observed the prevalence of functional dependency in 93.5%, and the mild dependency stood out in 40.7%. Medium social support was the most found, with 48.2%. The predominant dimensions of social support were the material dimension, followed by the emotional. There was a significant association (p ≤ 0.05) between very serious dependency and high social support. Conclusion: The results found allow us to reflect on the need for involvement of health professionals in strengthening the social support of patients with disabling diseases, such as the cerebrovascular accident.

title: Inhibitory effect on growth of pathogenic microorganisms induced by butenolides related to cadiolides

description: The increasing number of antibiotic resistant microorganisms requires the development of new drugs. In this context, natural cadiolides are promising leads as they present potent antimicrobial activity and low cytotoxicity. In this work we report the synthesis of 21 new cadiolide analogues. The synthesis involved a Diels−Alder cycloaddition/ cycloreversion reaction between an oxazole and different ynones, affording four intermediate butenolides (14a-d) in 61-81% yield. These intermediates were subjected to a vinylogous Knoevenagel condensation, followed by demethylation of the methoxylated compounds, affording all 21 analogues in good yields. The antibiotic activity of all compounds was evaluated against a panel of five microorganisms. The bioassays on the microbial growth showed that the cadiolides are more active for Gram-positive than Gram-negative bacteria, and have low activity against the fungus C. albicans. The most active compounds (14b, 15b, 15c and 16e) were effective against S. aureus showing IC50 in the range of 1.8-6.0 µg mL-1. The results also indicated that the nature and position of substituent groups on the aromatic moieties have some effect on the activities.

title: Methylene blue adsorption in Pinus elliottii (pine) and Drepanostachyum falcatum (bamboo) sawdust

description: ABSTRACT Kinetics, equilibrium and thermodynamic adsorption parameters were investigated for the adsorption of the methylene blue dye (MB) by means of the biosorbents Pinus elliottii (pinus) and Drepanostachyum falcatum (bamboo). The adsorption kinetics were described more precisely by the pseudo-second order model; the monocomponent equilibrium’s data were better represented by the Langmuir isotherm for the three temperatures studied (15, 25 and 35°C) and the thermodynamic parameters showed the adsorption process is exothermic, of a chemical nature and not spontaneous. The maximum adsorptive capacity of pinus was 47 mg L-1 and 38 mg L-1 bamboo for adsorption tests performed with MB (100 mg L-1 at 35°C). Finally, the biosorbents were considered promising for the adsorbate MB removal in aqueous matrix under pH value close to neutrality (6.5).

title: Education for ethnic-racial relations in the training of chemistry teachers: about law 10.639/2003 in higher education

description: In this paper, from the experiences of the Collective Ciata, we seek to elucidate theoreticalmethodological aspects that can establish the teaching of Chemistry for education for ethnic-racial relations and the implementation of law 10.639/2003. This research was based on the research-action technique. The recording of the interventions was done followed by transcription and analysis according to the theoretical reference of the analysis of the conversation. Our results show that racism is present in the classroom, therefore, also in Chemistry class. The teacher deals with the real school and must be trained to act in it. It is possible to promote curricular changes in favor of black populations by designing a curriculum that contemplates the ethnic-racial diversity of Brazilian society. Our results showed that it is possible to discuss in a Chemistry class subjects related to the proposals of the mentioned law, as well as, to approach concepts of related chemistry. For this purpose, knowledge was mobilized that were not present in the curriculum of the degree in Chemistry and, therefore, demanded training in service through the group of studies instituted by the Collective Ciata.
