title: Optimal feeding frequency for Heros severus (Heckel, 1840), an Amazon ornamental fish

description: ABSTRACT The influence of feeding frequency on growth performance, batch uniformity, and survival rate of severum (Heros severus) larvae and juveniles was investigated in two experiments. In the first, 200 five-day-old severum larvae with 3.20±0.31 mg and 6.20±0.39 mm were randomly distributed into 20 aquaria (1 L) and fed 500 Artemia nauplii larvae−1 day−1 for 15 days. In the second, 120 severum juveniles, 178.19±33.59 mg and 1.82±0.09 cm, were randomly distributed into 15 aquaria (300 L) and hand-fed a commercial diet (400.0 g kg−1 crude protein and 21.2 kJ g−1 gross energy) until apparent satiety for 30 days. For both experiments, feeding frequencies of one, two, three, four, and five meals day−1 were evaluated. We used four replicates for the first experiment and three for the second. At the end of both experiments, survival rate and batch uniformity were unaffected by the feeding frequency. Severum larvae fed three, four, and five meals day−1 showed higher final weight, weight gain, and specific growth rate, but only the larvae fed five meals day−1 showed higher final length and length gain than those fed once and twice day−1. Severum juveniles fed two, four, and five meals day−1 showed higher final weight, weight gain, and specific growth rate. Growth performance parameters of final length and length gain were not affected by feeding frequencies. Thus, we recommend that the optimal feeding frequency for severum larvae fed Artemia nauplii is three meals day−1 and for juvenile severum fed a commercial diet, the optimal frequency is two meals day−1.

title: Historical method and didactics of history in the United States of America (1880-1915)

description: ABSTRACT This article discusses and tells the transposition of an ideal historical method typical of the departments of history and education, colleges and normal schools to the printed documents destined for initial and continuing training of history teachers in the United States of America, between 1870 and 1916. Through the linguistic examination of the Union reports and manuals of history teaching methodology, we demonstrated that historians by formation expanded their performance on philosophers, sociologists, political scientists, economists and educators indicating that the heuristic analysis and synthesis should guide the teaching of history, thought and practiced in the United States since the last decade of the nineteenth century.

title: Useful plants referenced by the naturalist Richard Spruce in the 19th century in the state of Pará, Brazil

description: ABSTRACT The present work sought to study the biocultural collections made by the naturalist Richard Spruce in the 19th century while in the state of Pará, Brazil. The material is largely deposited in the Herbarium and the Museum of Economic Botany at the Royal Botanic Gardens, Kew, UK. Complementary studies were undertaken in Brazilian institutions to gather more information about the useful plants cited by Spruce for Pará and their respective vernacular names and uses in the 19th century. Information was also gathered concerning the current uses of the plants by analyzing contemporary ethnobotanical studies. A total of 54 vernacular names of useful plants were recovered, including 51 native species of which 33 are used for construction purposes, 18 as food resources, eight for medicinal purposes, and one species as an ichthyotoxin. It is interesting to note that 80 % of the uses described for these plants in the 19th century in Pará continue into the present day. It is hoped that the present work will serve to promote future studies involving biocultural collections that document the history of local populations and recognize the importance of traditional knowledge in the Amazon region.

title: Long-term settlement analysis of the dump site of Marambaia, Nova Iguaçu, Rio de Janeiro, Brazil

description: ABSTRACT This paper deals with the analysis of the compressibility of the old Marambaia dumping grounds’ MSW, located at Nova Iguaçu City (Rio de Janeiro) that was used as a waste dump from 1987 until 2003, when it was closed and remediated. The study was carried out based on superficial settlement monitoring data of reference points between 2008 and 2015. These data were analyzed considering the following compressibility models: Sowers, Meruelo, Ling et al. and Oweis. The results of the monitoring showed settlement values between 79 and 204 mm representing deformations in the range of 0.16 to 0.41% with regards to the of the landfill’s initial height. The models of Sowers, Merueloand Ling et al. render settlement values that are relatively close; revealing that, although being different in conception, both can be used to predict long-term settlements with a good approximation. The model of Oweis is the most elaborated of all models analyzed and predicted the greatest values for settlement.

title: Air Temperature Modelling in Distrito Federal – Brazil Region with Atmospheric AIRS Sensor Data

description: Abstract Remote sensing can be used to estimate meteorological data. Images of atmospheric variables obtained by the AIRS (Atmospheric Infrared Sounder) sensor aboard Aqua satellite, were used to estimate maximum, minimum and average daily air temperature in Federal District region – Brazil. Simple and multiple linear regression models were used with explanatory variables derived of diurnal and nocturnal AIRS data of surface temperature, relative air humidity and atmospheric water vapor over the period 2012-2016. The dependent variables were the maximum, minimum and daily average air temperature obtained by two meteorological stations located in the study region. The AIRS fittings showed R² = 0.62 and RMSE = 1.64 °C for the daily maximum air temperature, R² = 0.59 and RMSE = 1.50 °C for the minimum daily air temperature, and R² = 0.76 and RMSE = 1.45 °C for the daily average air temperature. Our results suggest that the AIRS data can yield accurate daily air temperature estimates for Distrito Federal – Brazil region.

title: Energy absorption of aluminum panels subjected to gelatin projectile impact

description: Abstract Digital image correlation (DIC) method has been widely used on dynamical experiments. This full-field and real-time method can fill in the gap of traditional point-based measurements of typical structures subjected to soft body impact such as bird strike. In order to get further understandings of soft body impact process, the present study analyzed the time-dependent energy exchange during impact experiments. The dynamic responses of the aluminum target panels were obtained using 3D digital image correlation method so that their displacement and strain field histories can be tracked. By introducing the material properties of the targets, their time-dependent stress state and consequently the strain energy can be calculated. With the help of time-dependent profiles of target panels, their energy absorption properties were theoretically analyzed, including the exchange of kinetic energy and plastic work. The results showed that when the impact loadings were increased, the plastic work generated by radial membrane force became the major source of energy dissipation. The transverse movements consumed more kinetic energies than rotatory moments. This research may provide a further application of DIC results and help to better understand the soft body impact process on targets with large deformations.

title: Longitudinal study of the symbolic representation capacity in children in the 3-6 cycle of Early Childhood Education in tasks related to mathematical dictation

description: Abstract In this work, mathematical dictations are used as a didactical-instrumental approach to perform a longitudinal study on the mathematical representation capacity in children at an early age. For this purpose, a field study was carried out with a total sample of 104 girls and boys of 1st, 2nd, and 3rd grade of Early Childhood Education. The results obtained, regardless of the age group, are: a) there is a positive relationship between the difficulty index of the dictates and the percentage of children who did not complete their task successfully; b) the repetition of tasks, within the same dictation, with equivalent difficulty fosters significant learning, regardless of the cognitive level, for girls and boys; c) according to the Van Hiele levels, greater difficulties are detected in the symbolic representation of objects when a higher degree of abstraction and mathematical complexity appear.

title: Functional independence measure in daily life activities in elderly with encephalic vascular accident sequels in the Sagrada Família Gerontologic Complex of Goiania

description: Abstract The encephalic vascular accident (EVA) is one of the greatest causes of permanent sequels that generate functional disability. This study aims to evaluate daily life activities of elderly with EVA through the Functional Independence Measurement (FIM). So the 14 elderly people with EVA sequel of the Gerontologic Complex Sagrada Família of Goiânia were evaluated through the FIM. FIM is an instrument that assesses the functional and cognitive capacity concerning six dimensions: self-care, sphincters control, transfers, locomotion, communication and social cognition. The result for motor control was 43, cognitive control was 17, and total MIF was 60. The results show that 57.1% presented modified dependence - assistance up to 50%, 21.4% had modified dependence - assistance up to 25% and 21.4%, complete independence. It is possible to conclude that the majority of the elderly have significant dependence for daily life activities, as consequence of low functional performance. In that way, those elderly require follow-up and directed orientations to allow a greater independence.

title: Ethnobotany of native cacti in the northeast region of Brazil: can traditional use influence availability?

description: ABSTRACT Documenting the uses of native species of Cactaceae in Northeast Brazil contributes to understanding how the inhabitants of this seasonally dry and low-rainfall region have used these resources, considering that some species of this family of Cactaceae are among the most endangered in the world. The aim of this research was to determine which species of Cactaceae occur in the study area and investigate the knowledge and recurrent uses associated with them, as well as the local availability of the species most used by residents. Ethnobotanical data were collected through semi-structured interviews with 59 heads of households. Guided tours were conducted for data collection and subsequent taxonomic identification of species. Use value and availability were determined for the most-used species in two predefined areas. Six native species were recorded and classified into eight categories. Columnar species had higher use values, while fodder and construction were the most cited use categories. Cereus jamacaru DC was the most-used species, with consequent interference in its availability due to significant reduction in the number of cladodes as a result of their constant removal from plants in areas of direct use for the purpose of fodder.

title: Conceptions about mathematics, its teaching and learning in Compendio Mathematico (1707) written by the Spanish Thomas Vicente Tosca (1651-1723)

description: Abstract The preface of a book is one of the main examples of paratexts, defined by Gérard Genette as those devices and conventions that enable a text to become a book. It can provide information about aspects such as the author's motivation and intention, the origin of the presented ideas, the potential readers, etc. In the particular case of a mathematical text devoted to some extent to teaching, the preface can provide information about the author's conceptions and beliefs about mathematics, its teaching and learning. In this work, we analyze the preface of Compendio Mathematico written by Thomas Vicente Tosca in 1707. This approach will allow us to have a view of how the teaching and learning of mathematics as well as mathematics itself were conceived during Spanish preenlightenment.

title: Pollen morphology of the Brazilian species of Bernardia Houst. ex Mill. and Tragia L. (Euphorbiaceae, Acalyphoideae)

description: ABSTRACT Bernardia and Tragia are the largest genera of the tribes Bernardieae and Plukenetieae (Euphorbiaceae,), with 68 and 125 species, respectively. Very few palynological studies have focused specifically on these genera in spite of the great pollen diversity observed in the family. The present study analyzed the pollen morphology of the Brazilian species of Bernardia and Tragia to identify diagnostic characteristics that could aid in their taxonomic circumscription. The pollen grains of 11 species of Bernardia and five of Tragia were obtained from specimens deposited in the HRB, HUEFS, PEUFR, RB and UFP herbaria, and were analyzed using light and scanning electron microscopy. The analyzed species had small- to medium-sized pollen grains in monads, with shapes from prolate to subprolate. The most significant differences were observed in aperture type and exine ornamentation. The pollen grains of Bernardia are tricolporate, with aperture margins varying from narrow to wide or with just slightly evident margins, and the exine varying between microreticulate and microreticulate-perforate. The pollens of Tragia are tricolpate with the exine varying between intectate pilate and verrucate. Some species of both genera could be diagnosed based on unique pollen characters, and four distinct morphological groups of Bernardia and two of Tragia were observed.
