title: Use of a robust alternative communication system in autism spectrum disorder: a case report

description: ABSTRACT This study aimed at investigating the impact of using a robust augmentative and alternative communication (AAC) system on the communication of a child with autism spectrum disorder. This longitudinal intervention research is a single case study. Skills were assessed with data obtained with the protocol Communication Assessment in Autism Spectrum Disorder at the beginning and end of the intervention. Receptive and expressive communication and behavioral skills increased respectively by 62.5%, 36.84%, and 55.53%. Hence, positive results were found in communication development using the robust AAC system in the intervention, as verified in the progress in receptive and expressive communication and behavioral skills.

title: Theoretical and computational simulation of the effect of the number of intermediate diaphragms on the live load distribution factors and structural response of a precast girder bridge

description: Abstract Intermediate diaphragms (ID) in bridges with precast girders are intended to improve load distribution among girders. Despite this, their efficacy has been doubted recently due to the complex construction tasks needed to join them to the girders. Accordingly, this work aimed to determine the effect of the number of IDs on the distribution of vertical loads and girders response of a simply supported bridge. Four bridge layouts (0, 1, 2, and 3 IDs) were analyzed using 3D computational grillage models. The load distribution factors from the models were compared to those calculated using the Engesser-Courbon and Fauchart methods to determine the latter’s accuracy in capturing the effect of the number of IDs. Moreover, the girders responses under the live loads in the current Colombian and Brazilian bridge design codes were assessed. The results show that the IDs have a more significant effect on the load distribution and deflection of interior girders than the exterior girders. Additionally, increasing the number of IDs reduced the maximum shear and torque while the bending moment and deflections remained nearly constant.

title: Creative Economy: an urban development strategy in Belo Horizonte

description: Abstract This article intends to build a basis for reflection on Creative Economy as an urban development strategy, adopted in Brazil in recent decades. An overview will be drawn about the new sector through a bibliographic review, taking as an example the city of Belo Horizonte, state of Minas Gerais, where state and municipal governments have incorporated that segment through cultural public policies aimed at valuing the local plan. The proposals mapped in the capital city will allow us to think about the hypothesis of adopting Creative Economy as a model of economic growth that corroborates the logic of spatial transformation through the practice of local urban entrepreneurship – based on a rentier-financial dynamics –, stimulating new studies in the area.

title: Perception of the educational environment by students from a public university in Northeastern Brazil

description: Abstract: Introduction: The quality of the educational environment is essential for effective learning in professional training. Objective: This research sought to identify and compare the educational environment perception of students from five different courses in health sciences graduation. Method: Cross-sectional, analytical study, quantitative approach, with 277 students from the courses of Physiotherapy, Nursing, Medicine, Occupational Therapy and Speech Therapy, enrolled in 2019, at a public university. The Dundee Ready Education Environment Measure (DREEM) instrument was used. This inventory has 50 closed questions punctuated on a Likert scale, which at the end, will assess five domains of the educational environment (learning, teachers, academic, atmosphere and social). The Kruskal-Wallis test was used (confidence interval of 95%) to compare the averages of the general score, individual items and domains between courses. Dunn’s method was used to multiply comparisons post hoc analyses. Result: The students’ general perception of their educational environment proved to be “more positive than negative”. The averages of learning, teachers, atmosphere and social domains presented differences between the courses (p &lt; 0.05). The research lowest average item was support for stressed students (p &lt; 0.05). The Medical Graduation showed worrying aspects regarding the perception of learning. Nursing was the best rated course in relation to the general perception of the educational environment. The Physiotherapy and Speech Therapy courses showed areas that deserve attention with regard to the perception of academic social relationships. Finally, the Occupational Therapy course highlighted areas of concern regarding the perception of students about teaching, teachers, academic performance and the atmosphere of the course. Conclusion: There are important differences in the perception of the educational environment by students between the courses evaluated. However, all the courses rated the educational environment more positively than negatively. The lack of support for stressed students is the most worrying area. Therefore, the knowledge of the students’ perception of the educational environment can offer greater direction in the search for the quality of education in health sciences professions.

title: Seasonal and pluviometric effects on the phenolic compound composition and antioxidant potential of Licania macrophylla Benth (Chrysobalanaceae), a medicinal plant from the Amazon rainforest

description: Abstract Licania macrophylla is a medicinal plant from the Amazon. It is mainly used in the form of a decoction and has been reported to contain several phenolic compounds. However, the effect of seasonality on the phenolic composition and antioxidant potential of this plant has not been well studied, especially in the Amazon region, an area affected by the rainy and less-rainy seasons. Therefore, we evaluated the seasonality of these aromatic compounds and the antioxidant potential of the extracts from L. macrophylla stem bark. We also determined the correlation between the extraction methods used and precipitation levels during each period for 1 year. The total flavonoid and phenolic content, DPPH-scavenging potential, percentage of phosphomolybdenum complex reduction, and iron-reducing power were quantified. The levels of phenolic compounds were the highest in June, whereas those of flavonoids were the highest in September and October; however, these differences were not significant. The extracts from April, November, and June showed the best results for DPPH scavenging, phosphomolybdenum reduction, and iron reduction power, respectively. Significant differences in the phenolic content and DPPH-scavenging activity were observed between the more- and less-rainy seasons. The total phenolic content was positively correlated with FRAP and DPPH, whereas flavonoid levels were negatively correlated.

title: Accumulation and efficiency of phosphorus use in irrigated cassava cultivars in the Brazilian semiarid region

description: ABSTRACT Phosphorus is of fundamental importance for the energy supply necessary for plant metabolism, but it is still understudied for important agricultural crops such as cassava. The objective of this study was to evaluate the accumulation and efficiency of phosphorus use in different cassava cultivars in the semiarid region. Two experiments were carried out during two agricultural seasons 2018/2019 and 2019/2020 in Mossoró, Rio Grande do Norte state, Brazil. The experimental design was randomized blocks, in split plots, with four replicates. In the plots, five doses of phosphorus (P) (0, 60, 120, 180, and 240 kg ha-1 of P2O5) were applied in the planting furrow, and four cassava cultivars (Água Morna, BRS Gema de Ovo, Recife, and Venâncio) were cultivated in the subplots. The cultivars Água Morna and Recife export more phosphorus through their roots. The cultivars Venâncio and Água Morna show greater agronomic efficiency when fertilized with 60 kg ha-1 of P2O5. The apparent P recovery efficiency presented the following order: ‘BRS Gema de Ovo’ &gt; ‘Água Morna’ &gt; ‘Venâncio’ &gt; ‘Recife’, with higher indices at the dose of 60 kg ha-1 of P2O5.

title: Comparison of the accuracy of residents, senior physicians and surrogate decision-makers for predicting hospital mortality of critically ill patients

description: ABSTRACT Objective: To compare the predictive performance of residents, senior intensive care unit physicians and surrogates early during intensive care unit stays and to evaluate whether different presentations of prognostic data (probability of survival versus probability of death) influenced their performance. Methods: We questioned surrogates and physicians in charge of critically ill patients during the first 48 hours of intensive care unit admission on the patient’s probability of hospital outcome. The question framing (i.e., probability of survival versus probability of death during hospitalization) was randomized. To evaluate the predictive performance, we compared the areas under the ROC curves (AUCs) for hospital outcome between surrogates and physicians’ categories. We also stratified the results according to randomized question framing. Results: We interviewed surrogates and physicians on the hospital outcomes of 118 patients. The predictive performance of surrogate decisionmakers was significantly lower than that of physicians (AUC of 0.63 for surrogates, 0.82 for residents, 0.80 for intensive care unit fellows and 0.81 for intensive care unit senior physicians). There was no increase in predictive performance related to physicians’ experience (i.e., senior physicians did not predict outcomes better than junior physicians). Surrogate decisionmakers worsened their prediction performance when they were asked about probability of death instead of probability of survival, but there was no difference for physicians. Conclusion: Different predictive performance was observed when comparing surrogate decision-makers and physicians, with no effect of experience on health care professionals’ prediction. Question framing affected the predictive performance of surrogates but not of physicians.

title: Trolox equivalent antioxidant capacity of Coffea arabica L. seeds

description: ABSTRACT The causes of the low desiccation tolerance and low longevity of coffee seeds have not yet been fully elucidated, and a full understanding of their complex physiology is of great interest. Among several alternatives, the loss of antioxidant capacity in seeds may be related to their rapid loss in quality during storage. The objective of this study was to determine the total antioxidant capacity of coffee harvested at different ripeness stages before and after the storage of seeds with different water contents and to relate antioxidant capacity to physiological quality. Seeds in the greenish-yellow or cherry stages, recently harvested or stored for nine months at 10 °C with 40, 30, 20 and 12% water content (wet basis - wb), were submitted to physiological and biochemical quality evaluations, and the Trolox equivalent antioxidant capacity (TEAC) was determined. The germination and root protrusion of coffee seeds from greenish-yellow and cherry fruits were not affected by drying, but seeds harvested at physiological maturity had greater vigor when the moisture content was lower. The quality of coffee seeds decreased during storage, and this decrease was greater in seeds stored with higher water contents. Coffee seeds in the greenish-yellow stage had a higher antioxidant capacity than those in the cherry stage when recently harvested, but there was a substantial reduction in this capacity during storage at both maturation stages. Coffee seed deterioration is related to a reduction in antioxidant capacity, and the isoenzymatic profiles of the antioxidant process are little affected by the seed maturation stage. The deterioration of coffee seeds during storage is related to a reduction in their total antioxidant capacity, regardless of their maturation stage, being more pronounced in the greenish-yellow stage.
