title: What does the Portuguese Language Textbook Propose When It Comes to the Genre Opinion Article? Investigations on the Portuguese Work: Context, Interlocution and Meaning

description: ABSTRACT In this work, the didactization of the genre of opinion article is investigated in the textbook collection Português: contexto, interlocução e sentido, with the objective to identify the teaching strategies of the opinion article genre and to reflect on the proposal of the work for the teaching-learning process. The relevance of the object of reflection is emphasized because the article of opinion is a textual/discursive genre that, when didactized, can favor the development of communicative competence for collective interest decision-making, and for the collection having received prominence in the evaluation of the National Textbook Program (2015) as the only one that has the discursive perspective of approaching the various axes of Portuguese language teaching, as well as updating the theoretical principles that underpin its work. This is a qualitative and interpretive documentary research, whose data were treated using elements of the categorical content analysis technique defined by Bardin (2009). It is theoretically based on the dialogue with the theoretical assumptions of Sociodiscursive Interactionism, by Bronckart (2006, 1999) and Schneuwly and Dolz (2004), in the concept of an opinion article by Gonçalves and Higa (2012), and in the perspective of textual production in a school context, by Antunes (2009, 2003). It is evident that, although there are strategies that may favor the elaboration of the opinion article, some problems are identified in the analyzed material, among them the absence of final production articulated with the work experienced in the process of reflection on gender; fragmentation of texts that support the discussion; as well as lack of articulation between elements that make up the chapter.

title: The Collaborative Construction of the Act of Teaching: Impacts of the A World of Englishes Project in the Context of Initial Training

description: ABSTRACT This article aims to analyze four aspects related to the implementation of an initial English teacher training project: option for teaching and the project; impressions on the project; impacts of the project on future teachers in training; and what challenges are presented in terms of academic and professional education. The project was based on theoretical conceptions of language as discourse (BAKHTIN, 2010; JORDÃO; FOGAÇA, 2007), critical literacy (CERVETTI; PARDALES; DAMICO, 2001; MUSPRATT; LUKE; FREEBODY, 1997) and English as a lingua franca (DEWEY, 2012; EL KADRI, 2010; SEIDLHOFER, 2001). The analysis was based on data generated from questionnaires answered by the furure teachers who participate in the project. The results point to a mature vision about the profession and the teaching performance, increase in the self-esteem of the future teachers and development of strategies to overcome individual and collective difficulties.

title: GRANULOMETRY AND ENERGY CONSUMPTION AS INDICATORS OF DISINTEGRATION EFFICIENCY IN A HAMMER MILL ADAPTED TO EXTRACTING ARROWROOT STARCH (Maranta arundinacea) IN COMPARISON TO STARCH EXTRACTION FROM CASSAVA

description: ABSTRACT The commercial sector of starch extraction has fully automated plants with a minimum scale of 200 ton.day–1, which extracts starch from maize and cassava in Brazil. Although these starches are commodities, the market demands starches with special properties obtained without chemical modifications. A higher-priced starch can compensate for small-scale extraction, as in the case of arrowroot starch, which would correspond to an alternative income for the producer. As a small-scale equipment was not available in Brazil, it was necessary to adapt a hammer mill for arrowroot starch extraction, which should have a performance similar to that obtained from cassava roots using industrial grinders. The degree of disintegration and energy consumption were adopted as the efficiency indexes. The hammer mill was equipped with two perforated plates. The results showed that use of an adapted hammer mill provides an average diameter of 74.64 ± 0.09 μm for perforated plate 1 (TP1) and 76.62 ± 0.06 μm for TP2; these results were equivalent to those obtained with cassava in the respective perforations which, in turn, was comparable to the degree of grinding obtained with large industrial equipment. The specific energy consumption needs for arrowroot disintegration varied from 31.47 to 48.91 kJ.kg–1, which was considered close to that calculated for large-scale industrial cassava roots grinders, reported at 37.03 kJ.kg–1.

title: Lexical diversity and lexical density description of news written by journalism student

description: ABSTRACT The aim of this study is to quantitatively describe the lexical richness in informative news articles written by journalism students through indicators of lexical diversity and lexical density. A comparative analysis of a corpus of news articles written by two groups of undergraduate students (first and fourth year) and a group of graduate journalists was performed. In order to compare the corpora, measures of lexical density and diversity were used while statistical tests were applied to analyze differences between the groups. Though results show differences, it is density the indicator where statistically significant differences were found. This would indicate that despite students having a command of a wide and varied lexis, the informative level and communicative capacity of their texts are insufficient compared to the requirements at a professional level.

title: T cell receptor excision circles as a tool for evaluating thymic function in young children

description: The thymus is a primary lymphoid organ responsible for the maturation of T cells as well as the immunological central tolerance. It is in the antenatal period and infancy that it plays its major role. In clinical practice, T cell receptor excision circles (TRECs) are considered a direct and reliable measure of the thymic function. TRECs are a by-product of DNA formation in gene rearrangement of T cell receptors. They are stable and they do not duplicate during mitosis, representing the recent emigrant T cells from the thymus. Despite their importance, TRECs have been neglected by physicians and there is a lack of data regarding thymic function during infancy of healthy children. In order to evaluate thymic function in the first years of life, we propose measuring TRECs as a valuable tool. One hundred and three blood samples from children and adolescents between 3 months and 20 years of age were analyzed. The mean TRECs count was 136.77±96.7 copies of TRECs/μL of DNA. The individuals between 0 and 5 years of age had significantly higher TRECs values than those between 10 and 20 years of age. No significant difference was observed in TRECs values among age groups below 5 years of age. An inverse correlation between TRECs and age was found (r=0.3 P=0.003). These data highlight and validate the evidence of decreased thymus function with age, even during infancy. Awareness should be raised with this important albeit ignored organ.

title: Advances in fruit crop propagation in Brazil and worldwide-apple trees

description: Abstract Apple production has been an important economic activity worldwide. The wide dissemination and cultivation of apple trees in several regions of the world is due to the development of propagation techniques from its domestication to the present time. Apple trees can be propagated by seeds, restricted to the use in breeding programs, and multiplied by several methods of vegetative propagation, both for rootstocks and apple scion cultivars. Considering the high technological level currently used in apple crop management, plant propagation plays a very important role in order to enable seedling production with high morphological quality and free of diseases, requiring new advances and propagation improvements in new releases of rootstocks and apple scions.

title: Advances in propagation of Ficus carica L.

description: Abstract Fig tree (Ficus carica L.) stands out due to its range of cultivation and easy adaptation to diverse edaphoclimatic conditions. In addition to its adaptability, fruits have nutraceutical characteristics and are used in industry and for fresh consumption, widely appreciated by the world cuisine. Due to lack of manpower and phytosanitary problems, the area planted in Brazil has decreased recently. To overcome these obstacles, the production of quality seedlings is the first step to obtaining productive and healthy orchards. Therefore, the aim of the present literature review was to gather data referring to advances in research related to the fig tree propagation. Currently, the methods found for fig tree propagation consist of seedling production, where entomophilic or vegetative pollination occurs. Commercially, the propagation method by cutting is still the most used for this crop; however, other methods can also be used, such as the use of burrs or plunging and grafting techniques and tissue culture. Although there is a diversity of propagation methods and new technologies being developed, cuttings remain the most feasible method. In addition, obtaining healthy and quality seedlings is one of the main problems currently found in ficiculture, since, in addition to the scarcity of studies related to propagation, the use of resistant cultivars and pathogen-free substrates should be prioritized due to susceptibility of fig trees to nematodes. Thus, further studies should be carried out in order to seek new information on the cultivars most adapted to each locality, as well as improvements in propagation and cultivation techniques.

title: GEOSTATISTICAL MODELING OF SOYBEAN YIELD AND SOIL CHEMICAL ATTRIBUTES USING SPATIAL BOOTSTRAP

description: ABSTRACT The goal of this study was to use the spatial bootstrap method to model the spatial dependence structure of soybean yield and soil chemical attributes in an agricultural area. The study involved developing confidence intervals in probability plots to determine the probability distributions assumed by the data; determine the empirical distributions of the semivariances and model parameters, allowing to obtain statistics and confidence intervals; and to construct maps for the variables. The quantile-quantile plots indicated that the data follows a normal distribution. The confidence intervals for the semivariances helped to model the spatial dependence structure, and the descriptive statistics of the bootstrap replicates of the model parameters allowed to test the consistency of the estimates. The soil chemical attributes (calcium, potassium, and organic matter) were at levels suitable for soybean cultivation. However, the pH was below the ideal range in most of the study area, and water stress during cultivation decreased the mean yield. Therefore, according to the results, a recommendation to the farmer is to correct the soil pH to increase the yield.
