title: In vitro efficacy of essential oils with different concentrations of 1,8-cineole against Rhipicephalus (Boophilus) microplus

description: Abstract The aim of this study was to evaluate the acaricidal activity of essential oils from three species of plants with intermediary concentrations of 1,8-cineole against the tick species Rhipicephalus (Boophilus) microplus. For this purpose, five serial concentrations (100.0, 50.0, 25.0, 12.5, 6.2 mg/mL) of essential oils from Mesosphaerum suaveolens (L.) Kuntze, Ocimum gratissimum L. and Alpinia zerumbet (Pers.) B. L. Burtt & R. M. Sm. were used on larval packet and adult immersion tests. The essential oils were analysed by gas chromatography-mass spectrometry (GC/MS) and gas chromatography-flame ionization detection (GC-FID), being detected 35.8, 24.7 and 24.0% of 1.8-cineol in the oils of M. suaveolens, O. gratissimum and A. zerumbet, respectively. The lethal concentration (LC 50) of each oil for larvae and engorged females was calculated through Probit analysis. All essential oils showed high efficacy (≥ 95.0%) on engorged females at the 100.0 mg/mL concentration. In regards to larvae, O. gratissimum (LC 50 = 11.9 mg/mL) was the most potent, followed by the A. zerumbet (LC50 = 19.7 mg/mL) and the M. suaveolens (LC50 = 51.6 mg/mL) essential oils. These results show that other compounds interfere with 1,8-cineole action.

title: MULTIVARIATE ANALYSIS OF PEANUT MECHANIZED HARVESTING

description: ABSTRACT The peanuts harvesting mechanization is affected by the soil physical characteristics and it may increase the losses due to the production of pods in subsurface. The objective of the experiment was to identify the clusters through multivariate exploratory approaches from similarity in six soil textures (very clayey, clayey, silty clayey loam, clayey loam, sandy loam and sandy) in the state of São Paulo, Brazil, determining the main agronomic variables that most influenced the clustering division to assist the decision-making process in peanuts mechanized harvesting. The data were analyzed by the multivariate exploratory that is performed to simplify the description of a set of interrelated variables, using: yield, maturity, soil and pod moisture content, windrow width and height, visible and invisible digging losses, and gathering losses, as agronomic indicators of quality. The low and high clay content were grouped into clusters I and III, respectively, according to the agronomic traits of the peanut crop. The principal components analysis (PC) allowed a single distribution of accesses since only two eigenvalues were higher than “one”: the highest eigenvalues of 4.51 and 1.79, resulted in a Biplot that explained 70% of the original variability, 50.11% and 19.89% of which in the PC1 and PC2, respectively. The multivariate analysis indicated that high peanut yields in soils with low clay are correlated with the losses during the peanut mechanized harvesting operation.

title: An Ingenious Scheme: The Assembly of the International Engineering Congress of 1922 and Diplomatic Relations between Brazil and McGraw-Hill

description: Abstract In 1922, the Engineering Club of Rio de Janeiro hosted the International Engineering Congress. The organizing committee was headed by Verne Leroy Havens, editor-in-chief of the Spanish language Ingeniería International magazine which was published in the US by McGraw-Hill. The magazine's broad circulation was a framework through which a transnational perspective can help us to understand this organization and its social fabric as it stretched across the continent and created an enduring network of industrial relations and technical culture. For its part, the Engineering Club was compelled by court order and the Brazilian government to organize and host the event. Diplomatic and economic relations with the United States were at stake, together with those of the other major South American countries. The motives and maneuvering behind this Congress in these days before the Good Neighbor Policy can still be glimpsed.

title: Ultimate flexural strength of prestressed concrete beams: validation and model error evaluation

description: Abstract In this work a computational model is presented to evaluate the ultimate bending moment capacity of the cross section of reinforced and prestressed concrete beams. The computational routines follow the requirements of NBR 6118: 2014. This model is validated by comparing the results obtained with forty-one experimental tests found in the international bibliography. It is shown that the model is very simple, fast and reaches results very close to the experimental ones, with percentage difference of the order of 5%. This tool proved to be a great ally in the structural analysis of reinforced and prestressed concrete elements, besides it is a simplified alternative to obtain the cross section ultimate bending moment.

title: Combination of uv-c radiation and chitosan films enriched with essential oils for fungi control in papaya ‘Maradol’

description: Abstract Anthracnose and soft rot cause deterioration of quality as well as large losses during post-harvest handling of papaya fruits. The single strategies for disease control is little efficient. We analyzed the effect of to integrate control strategies on the incidence of disease caused by the inoculation of spores of the fungi Colletotrichum gloeosporioides (Penz.) and Rhizopus stolonifer (Ehrenb.) into papaya (Carica papaya L.) ‘Maradol’. The following treatments were evaluated: a combination of the use of composite films made with chitosan (15 g L-1) enriched with clove, thyme and / or lime essential oils, (EO) (5 or 10 mL L-1 of each EO) and three irradiation UV-C doses (0.97 kJ·m-2, 2 kJ·m-2 y 2.88 kJ·m-2), applied at 12, 24, and 48 h post-inoculation of phytopathogens spores. The treatment where combined coating with 10 mL L-1 of clove EO and 10 mL L-1 of thyme EO and a UV-C irradiation at dose of 2.88 kJ m-2 (B1T92) applied at 24 h post-inoculation was able to maintain the disease incidence lower than 25% (for both fungi) during nine days of storage at tropical room conditions (28 ± 3 °C and 80% RH). The same treatment reduced the specific rate of the disease, with values of 0.549 and 0.029 d-1 for C. gloeosporoides and R. stolonifer, respectively. Other treatments (B2T62, B1T34, B1T34, and B1T94) had antifungal activity (mean values of incidence of 35% throughout storage) for R. stolonifer. These results demonstrate that the synergistic effect of the use of biofilms enriched with EO and UV-C irradiation controls the development of fungi causing anthracnose and soft rot in Maradol papaya fruits.

title: Spatial Variability of Soil Fauna Under Different Land Use and Managements

description: ABSTRACT Geostatistics allows the evaluation of the distribution pattern of data with high spatial variability in agricultural systems. This study aimed to evaluate the spatial variability of biological diversity indices of soil fauna under different land (agriculture and forest). Samples were collected in seven areas (millet, soybean, corn, eucalyptus, pasture crops, and preserved and disturbed Cerrado), in Maranhão state, Brazil. The soil fauna was caught trapped in pitfall traps, installed 3 m away from each other. In each area, 130 traps were maintained for seven days. After this period, they were removed and their content transferred to bottles and taken to the laboratory, where the insects were screened and identified at the level of orders and families. Eight indices were calculated, namely: individuals trap-1 day-1, Jackknife richness estimator, the Simpson, McIntosh, Shannon, and total diversity, and Simpson dominance, and Pielou equitability indices. The spatial variability was derived from the semivariograms fitted to Gaussian, spherical, and exponential geostatistical models. Statistical analysis showed medium values of the coefficient of variation for millet, except for the indices individuals trap-1 day-1 and McIntosh diversity, which were considered high. The values of the correlation matrix were negative for some indices, suggesting an inverse relationship. For millet, corn, eucalyptus, disturbed Cerrado, and pasture areas, the Shannon diversity index exhibited a pure nugget effect. For the areas of millet, corn, disturbed Cerrado and pasture, the total diversity index was adjusted to the Gaussian model. The degree of spatial dependence was considered high for the individuals trap-1 day-1 and Pielou equitability indices for millet. Only for soybean and pasture similarity in the scaled semivariograms was observed for the spatial variability of the indices, indicating similarity of performance. Soil management and land use affect the patterns of soil fauna abundance, richness, and diversity. The presence of groups such as Araneae, Diplura, and Poduromorpha are related to ecological equilibrium, quality, and sustainability of the agricultural systems studied.

title: Linguistic realizations and genre instantiation from the systemic-functional perspective

description: ABSTRACT The aim of this article is to draft a reading path oriented by relevant aspects of systemic functional theory which reveal the instantiation of genres of the story family. We focus on the notions of language stratification, realization and instantiation to explain the notion of genre in Systemic-Functional Linguistics and to analyze the linguistic realizations that demonstrate the socio-communicative purpose and the schematic structure of genre within a sample of texts socially recognised as fables, frequently used in the Brazilian school context.

title: CHEMICAL AND FUEL PROPERTIES OF FORESTRY WASTES FROM PINE PLANTATIONS

description: ABSTRACT Power plants have been using forestry biomasses to produce thermal and electrical energies. However, these industries lack of reliable parameters about their raw material in order to consolidate their position in this market. The present study aimed to characterize forestry wastes from pine (Pinus elliottii) plantations leftover of wood logs processing units. Wood, bark and a mixture of both of them were characterized by prompt (total moisture, hygroscopic moisture, ashes, volatile matter and fixed carbon contents), elementary (S, C, H, N and [O + Halogens] contents), and via wet (holocellulose, lignin and extractives contents) chemical analyses. Indeed, basic density and fuel properties (gross and net calorific values) were also determined. Compared to the wood, the bark presented higher extractives content, which affected the ashes content. Regarding the energetic properties, the bark showed the highest properties, but a detrimental character from an environmental standpoint. The wood-bark mixture presented intermediate properties between these two forestry wastes, but with more approximation to the wood.
