title: Studies and research of and about the body: the production of ProPosições (1990-2018)

description: Abstract Studies and research of and about the body have very recently become subject of investigation in the human sciences and also in the field of education. This article aims to present the production of the journal Pro-Posições, related to studies and research on this topic, developed from different approaches and theoretical frameworks, from 1990 to 2018. This production was searched by title, abstract, and keywords, using the following descriptors: corpo (body); cuerpo (body); educação física (physical education); ginástic (gymnastic); gímnic (gymn); dança (dance); esport (sport); lazer (leisure); recrea (recreation). It was possible to identify a significant set of 105 publications covering articles, presentations, reviews, and other texts, which are part of the different sections of the journal. This shows that this journal is tuned to emerging, original, and/or little-considered topics, and it can be recognized as a publication of the education area that is strongly open to broad and qualified dialogue.

title: Reading propositions: a perspective of the archive of production in the fields of Philosophy and Philosophy of Education in the 30 years of the Brazilian journal Pro-Posições

description: Abstract In this article we aim to collect and comment on the production in the fields of Philosophy and of Philosophy of Education published during the 30 years of the Pro-Posições journal. To do so, we organized into three thematic parts a set of thematic occurrences that are present, at the same time, in three decades of publications. The first decade covers the years from 1990 to 1999, highlighting the theme of Education and its republican value in the Brazilian redemocratization, with emphasis on critical thinking; the second decade, between 2000 and 2009, brings to light a series of analyses concerning the millenary challenges for the field of Education, mainly the ethical-political problematization of society in general; the last decade, from 2010 to 2018, evidences the increase of the presence of Philosophy and Philosophy of Education in the field of Education, entailing themes such as differences, inclusion, and subjectivities. Besides observing that Philosophy and Philosophy of Education are remarkable fields over the 30 years of the Pro-Posições journal, we argue that the same problematizations of all three decades of publication are urgent for reiterating one of the struggles of critical thinking in the defense of the republican Education and of its democratic principles, in addition to drawing attention to the urgency of the place of differences and multiplicities in the field of Education.

title: Body education in the program of Integrated Centers for Public Education – CIEPs: an educational project written by modernity

description: Abstract The objective of this article is to analyze how the project of the Integrated Centers of Public Education (CIEPs) presented a version of civilizational project that had the body of the child of the popular classes as object of pedagogical intervention. The question that mobilizes us is: how were corporal practices embedded in the CIEPs conception in order to validate the education of bodies in the school space? We have analyzed the administrative documents related to the Special Education Department of the Darcy Ribeiro Foundation. It was concluded that school times and spaces, prescribed in the documents, indicated a proposal of intervention in the body aiming: refinement of behavior, formation of new habits, production of new sociabilities and new relationship between school and community.

title: Leaf area estimation of cassava from linear dimensions

description: ABSTRACT The objective of this study was to determine predictor models of leaf area of cassava from linear leaf measurements. The experiment was carried out in greenhouse in the municipality of Botucatu, São Paulo state, Brazil. The stem cuttings with 5-7 nodes of the cultivar IAC 576-70 were planted in boxes filled with about 320 liters of soil, keeping soil moisture at field capacity, monitored by puncturing tensiometers. At 80 days after planting, 140 leaves were randomly collected from the top, middle third and base of cassava plants. We evaluated the length and width of the central lobe of leaves, number of lobes and leaf area. The measurements of leaf areas were correlated with the length and width of the central lobe and the number of lobes of the leaves, and adjusted to polynomial and multiple regression models. The linear function that used the length of the central lobe LA = -69.91114 + 15.06462L and linear multiple functions LA = -69.9188 + 15.5102L + 0.0197726K - 0.0768998J or LA = -69.9346 + 15.0106L + 0.188931K - 0.0264323H are suitable models to estimate leaf area of cassava cultivar IAC 576-70.

title: Microstructure and Thermal Analyses of Cu87-xAl13Nbx High-Temperature Shape Memory Alloys

description: This paper presents a thermal and microstructural characterization of Cu87-xAl13Nbx (wt%) high temperature shape memory alloys (HTSMA), with Nb contents ranging from 1 to 3%. The alloys were obtained by arc melting under argon atmosphere. Thermal characterization was performed by differential scanning calorimetry (DSC), revealing that the phase martensitic transformation of all the studied alloys occurs in the range of 200 ºC to 450 ºC. Thermal cycling in this temperature range caused the martensitic transformation to disappear after approximately 6 cycles. However, a new heat treatment at 850 ºC followed by water quenching causes the martensitic transformation to be recovered. Microstructural characterization was performed using optical microscopy (OM) and scanning electron microscopy (SEM), revealing the presence of Nb precipitates in a Cu-Al martensitic matrix, mainly in the Nb-rich compositions. These different microstructures with Nb particles cause a hardness variation that initially decreases between 0.5 %Nb (275HV) and 1.0 %Nb (225HV), then increasing continuously up to 3.0% Nb (380HV).

title: Interference of Volunteer Corn from Different Origins and Emergence Time on Soybean Yield and Stress Metabolism

description: ABSTRACT: Volunteer corn occurrence with soybean is favored by the glyphosate-resistant (GR) corn cultivation preceding soybean and no-tillage systems. Volunteer corn interference causes significant losses in soybean grain yield. The levels of crop losses change with the corn density, origin, and time of emergence. High levels of weed interference in crops can result in the production of reactive oxygen species and lead to the occurrence of oxidative stress. The objectives of this study were to evaluate the effects of interference of (1) different origins (individual plants and clumps) and times of emergence of volunteer corn on soybean growth, yield components, and grain yield loss; and (2) if the volunteer corn interference causes oxidative stress in soybean. Field experiment and laboratory analyses were performed. The evaluated variables were soybean yield components, grain yield, hydrogen peroxide - H2O2 content, and antioxidant enzyme superoxide dismutase - SOD, catalase - CAT, and ascorbate peroxidase - APX activities. Volunteer corn interference reduced the yield components and soybean yield. The highest yield losses were observed with volunteer corn clumps regarding individual plants. The interference of volunteer corn emerged 10 days before or on the same day as soybean caused the greater yield losses than those emerged 10 days after, independently of its origin. The content of H2O2 and enzyme SOD, CAT and APX activities changed in soybean leaves in response to the interference of volunteer corn plants and clumps. However, the results indicate that the volunteer corn interferences does not cause oxidative stress in soybean.

title: Resistance of the stable fly, Stomoxys calcitrans (Diptera: Muscidae), to cypermethrin in outbreak areas in Midwestern Brazil

description: Abstract Population explosions of the stable fly (Stomoxys calcitrans) have become a serious concern for livestock producers near sugarcane mills in some regions of Brazil due to the insect’s massive reproduction on sugarcane byproducts and waste. Despite the limited efficiency of insecticides for controlling stable fly outbreaks, producers still rely on chemical control to mitigate the alarming infestations in affected areas. This study evaluated the susceptibility of S. calcitrans populations to cypermethrin in the state of Mato Grosso do Sul, Brazil. Stable flies were tested from three field populations and two colonies, established from flies previously collected at sugarcane mills. Wild flies were collected with Nzi traps in areas of sugarcane plantations. Both wild and colonized flies were exposed to eleven concentrations of cypermethrin in impregnated filter paper bioassays. All the populations proved to be resistant to cypermethrin, with resistance factors among field populations ranging from 6.8 to 38.6. The intensive use of insecticides has led to the development of pyrethroid resistance in stable fly populations in the proximities of sugarcane mills in the state of Mato Grosso do Sul.

title: The Normal Course of the Esef and the pioneering formation of Physical Education teachers in Rio Grande do Sul (1940-1956)

description: Abstract The present study aims to understand how the formation of teachers occurred in the Normal Course of the School of Physical Education (SPE) in the state of Rio Grande do Sul (RS), during the period in which it remained in operation (1940-1956). The construction of the historical text was guided by the theoretical and methodological assumptions of Cultural History, mobilizing the concepts of practices, representations and appropriation and, understanding the evidence according to the understanding of the “indiciary paradigm”. Through the collating and analysis of the research documents, it was possible to enter into the symbolic spaces of the SPE, demarcating the Normal Course as a place of formation permeated by representations from different groups that sought, through their practices, to legitimize their discourses. In this scenario, women began to occupy different positions, imprinting their identity to an environment permeated by representations predominantly military and medical.

title: Evaluation of Antifungal Potential of Leaf Extract of Chenopodium murale Against Fusarium oxysporum f. sp. lycopersici

description: ABSTRACT: The present study was performed to evaluate antifungal activity and GC-MS analysis of leaf extract of Chenopodium mural against Fusarium oxysporum f. sp. lycopersici (FOL), a highly problematic soil-borne pathogen of tomato. Dried leaves of C. murale were extracted with methanol for 2 weeks and after evaporating the solvent on a rotary evaporator, antifungal bioassay was carried out against FOL. All concentrations (1 to 5%) significantly reduced FOL biomass by 14-45%. The remaining methanolic extract was fractioned with n-hexane, chloroform and ethyl acetate and all these fractions were assayed for their antifungal potential. A 200 mg mL-1 concentration of various sub-fractions reduced fungal biomass significantly by 94-98% over control. All the sub-fractions were subjected to GC-MS analysis that revealed presence of 32 compounds in n-hexane, 2 compounds in chloroform and 13 compounds in ethyl acetate sub-fraction. The predominant compounds in n-hexane sub-fraction were hexadecanoic acid, methyl ester (14.64%), methyl linolenate (16.61%) and g-sitosterol (13.53%). In chloroform sub-fraction, bis (2-ethylhexyl) phthalate (92.31% and in ethyl-acetate sub-fraction, ethyl butyrate (19.57%), dihexyl phthalate (11.19%) and dioctyl phthalate (12.16%) were present in higher concentration.

title: Documentation of Folk Herbal Uses of Medicinally Important Wild Vegetables Used by the Tribal Communities of Sargodha Region, Pakistan

description: ABSTRACT: This preliminary study provides the traditional consumption of wild vegetables that mostly grow as weeds (&gt;50%) and that are also medicinally important in the rural communities of Sargodha region, Pakistan. Through different surveys and interviews with key informants, data on perception, gathering, preparation and use of 40 wild vegetables belonging to 27 families were collected. Most common wild occurring family was Cucurbitaceae. The most of the plants found were from herbs followed by trees and shrubs. According to mode of consumption, majority of the plants are cooked while others are used as in salads form while juices, spices, pickles, raw form (their parts like fruits), jams etc. are also used. Most commonly used plant parts were fruits followed by shoots and leaves. According to medicinal view of collected wild vegetables, most of the plants are used for gastrointestinal disorders. The present study confirms the findings that the rural communities can harvest wild edible plants especially weeds as a survival strategy. It presents the baseline data on the use of plant resources as wild edible vegetables by the native communities of the area. Moreover, many potential medicinal plants should be the focus of future research, especially from the phytochemical point of view for boosting pharmaceutical industries.

title: Use of Sunflower and Soybean as Bioindicators to Detect Atrazine Residues in Soils

description: ABSTRACT: Atrazine is selective for maize, sugarcane and sorghum and may interfere with successor crops such as sunflower and soybean. Despite this problem, there are few studies about the residual effect of this herbicide in these crops. Thus, the objective of the research was to evaluate the residual effect of atrazine through bioavailability of the herbicide in sandy and clayey soils, using soybean and sunflower as bioindicators. The design was completely randomized with four replications and a 2 × 7 + 1 factorial scheme, that is, two doses (2,000 and 2,500 g ha-1), seven application times (0, 15, 30, 45, 60, 75 and 90 days between application (DBA) of herbicide and bioindicator sowing) and one control without application. Dry mass and chlorophyll content of the bioindicators were evaluated at 20 days after sowing. The accumulation of dry mass of the bioindicators in the two types of soil was reduced at 90 DBA. The chlorophyll content at 0 DBA was zero for soybean and sunflower, due to the reduction of dry mass by approximately 100%. It was concluded that the residual effect of atrazine at a dose of 2,500 g ha-1 was higher in clayey soils due to the low bioavailability of the product in the soil solution. Therefore, it is recommended to sow sunflower and soybean in both soils after 90 DBA, because atrazine interferes with the chlorophyll content and percentage of dry mass reduction.
