title: Effect of Dicamba and Adjuvant Combination on Parthenium Control, Fodder Yield and Yield Components of Forage Sorghum (Sorghum bicolor)

description: ABSTRACT: Parthenium is an important weed which poses severe threats to yield and quality of sorghum and many other summer season crops, worldwide. As in other field crops, parthenium also reduces yield and quality of forage plants in forage crops so it should be controlled in forage and fodder crops. Parthenium control efficacy of five herbicide treatments (including dicamba at 304.5 g a.i. ha-1 (full rate) alone, dicamba at full rate + 1% ammonium sulphate, dicamba at full rate + 2% ammonium sulphate, dicamba at 75% rate + 1% ammonium sulphate and dicamba at 75% rate + 2% ammonium sulphate) was tested in field trials for two consecutive years (2013 and 2014). One manual hoeing three weeks after crop emergence was also performed as a treatment and weedy check was kept as control. Application of the full rate of dicamba with 2% ammonium sulphate showed the lowest parthenium dry weight (16.5 g m-2 and 23.5 g m-2) and NPK uptake that seem to be due to the highest parthenium control efficiency of 79.6% and 73.8% during 2013 and 2014, respectively. This weed management strategy also gave maximum values of yield components of forage sorghum, including plant height (261 and 254 cm), stem diameter (0.97 and 0.84 cm), leaf area per plant (3,072 and 3,041 cm2), fresh fodder yield (63.4 and 60.9 t ha-1) and dry matter yield (17.4 and 15.8 t ha-1) in 2013 and 2014, respectively. Highest net return and marginal rate of return (346 and 356% in 2013 and 2014, respectively) were also found when the full rate of dicamba with 2% ammonium sulphate was applied. In conclusion, tank-mixed application of dicamba at 304.5 g a.i. ha-1 with 2% of ammonium sulphate proved to be better for efficient control of parthenium weed in forage sorghum.

title: Patterns of science teaching practice with the use of an instrument designated “X ray of practice”

description: Abstract The article describes a proposal for an instrument for collecting a description of the operational practice of teachers, allowing for access to essential educational events that structure their practices, the physical bone of their theory practice, designated X-ray of the practice. The methodology previously proposed to identify the teachers’ pedagogical sequences is, in this work, used as an interpretive matrix by the investigator of the descriptions of the teachers’ practice, experiencing its usefulness and contributing to the validation of the assumptions in its construction. The article describes the methodological procedure in the application with a group of teachers, the process of inference by the investigator, and examples of the practice patterns found in the studied group: a pattern radically more transmissive, a transmissive pattern based on a practical activity and a pattern with constructivist indications.

title: A Intermodalidade no Transporte de Etanol Brasileiro: aplicação de um modelo de equilíbrio parcial

description: Abstract: The search for renewable energy sources has increased the world demand for ethanol. Brazil is the second largest producer, but the costs to transport this production are increasing. The aim of this paper is to analyze alternatives to transport ethanol in relation to the current logistics conditions in Brazil. To perform this, it is proposed to apply a partial equilibrium model in the form of a Mixed Complementarity Problem (PCM). Three scenarios were evaluated: the first represents the current perspective, road and railroad routes are practiced. In Scenario 2, a 15% reduction in the value of rail freight was estimated, and scenario 3 includes new pipeline projects underway in the country. Scenario 3 presented the best commercialization volumes with a 0.20% increase in relation to the baseline scenario and an increase in foreign exchange of US$ 27 million, indicating that road projects that prioritize intermodality, mainly through pipelines, imply reductions in transportation costs and an improvement in efficiency of the logistic system. As a future proposal, it is suggested to include the US subsidy for ethanol, since such a parameter could alter Brazilian competitiveness.

title: ENVIRONMENTAL VARIABLES AND QUALITY TOOLS APPLIED TO THE OPERATOR OF AN AGRICULTURAL MICROTRACTOR

description: ABSTRACT Work in the field is characterized as unstructured because it is performed in inconvenient postures, without a fixed workstation, exposing the worker directly to the sun and other inclement weather. This may interfere in the health and the performance of the activity. The objective of this work was to characterize the environment of the agricultural microtractor operator, evaluating the thermal comfort during the activity in the municipality of Quixadá, CE. A model TC14 Super Yanmar Agritech microtractor, coupled to a rotary spindle, was used. For the measurements of the environmental variables, sensors and devices were installed on the operator and in the microtractor. The experimental design adopted the assumptions of statistical quality control. Fifteen collections were done daily at different times for three consecutive days. The data obtained were indices of thermal discomfort and thermography, both of which were analyzed by sequential graphs (run charts), control graph (Xbar-R chart), and scatter plot. At all rates, the work performed proved to be inadequate, exceeding the operator's capabilities and limitations. It was concluded that the activity performed by the microtractor operator is stressful. Measures should be taken to improve working conditions without affecting the operator's health.

title: Particles panels prepared from dendê mesocarp as an alternative to MDF used in civil construction

description: ABSTRACT The lack of forest resources integrated with the need of purchasing more environmentally friendly products requires the use of other types of biomass besides wood in the construction sector. Therefore, the dendê mesocarp - waste arising from the agro-industry and with great use potential in developing new materials - is an alternative in the preparation of lignocellulosic panels to replace MDF (Medium Density Fiberboard), that is conventionally used. Thus, this work demonstrated the feasibility of the production and the structural integrity of this type of panel in the manufacture of building blocks to be used in civil construction through a comparative study of their properties with the MDF panels. The methodology consists in performing characterization tests in panels through determining their physical (water absorption, swelling and density) and mechanical (flexion resistance and modulus of elasticity) properties, besides analysing the morphology of the panels produced by the Scanning Electron Microscopy (MEV) technique, performing a chemical (via infrared spectrum Fourier transform) and thermal analysis through derived thermogravimetric curves. The results obtained suggest that the production of these panels without a binder, obtained by the incorporation of dendê mesocarp, adds value to the production chain of dendê, in addition to emerge as an alternative to the challenges inherent to the traditional production of wood panels and, consequently, is considered as an option of a constructive element to be integrated with the construction.

title: Effects of the electronic invoice program on the increase of state collection

description: Abstract This article aims to verify if the implementation of the Electronic Invoice program (EI), generated an increase in the collection in the state of Goiás, Brazil. For the research, means test analysis (t-test) was used along with the estimation of regressions difference-in-differences. The results indicated that the average collection in the state of Goiás was statistically higher in the period after the implementation of EI and that the increase in the collection from companies required to issue EI was superior to the collection from those not required to during the period of investigation. Therefore, although the main focus of EI is not the increase in tax collection, it can be observed that the institutionalization of a program of standardization and sharing of fiscal documents included improvements in the inspection processes of the tax administration, increasing the collection of state taxes through the reduction of tax default.

title: Growth and Development of Ipomoea Weeds

description: ABSTRACT: Weeds reduce the productive potential of crops. Plants of the Ipomoea genus, besides competing for water, light, space and nutrients, create problems in crop harvests due to their volatile stems. The objective of this work was to evaluate the growth and development of five Ipomoea species. For such, Ipomoea grandifolia, Ipomoea hederifolia, Ipomoea nil, Ipomoea purpurea and Ipomoea quamoclit plants were analyzed during the summer and winter season. Five destructive and periodic growth evaluations were carried out for each study, where leaf number, leaves, stems, roots and the total biomass were analyzed. Phenological stages of the plant development were also evaluated for emergence, flowering and maturation sub-periods by degree-days, totalizing five treatments, conducted in a completely randomized design with four replicates. The phenology averages were analyzed according to the Hess scale, and the growth data through nonlinear regressions. I. quamoclit and I. grandifolia obtained the highest number of leaves in the summer and the winter, respectively. I. nil obtained greater accumulation of leaf and stem dry biomass in both seasons. I. grandifolia obtained greater root development in both periods. I. quamoclit presented reduced cycle times when compared to the other species, especially I. hederifolia and I. grandifolia, which presented larger cycles. Based on the results, I. grandifolia probably shows greater interference with agricultural crops due to high root growth, high leaf production and longer cycle. Shorter-cycle species, such as I. quamoclit, when present, should require shorter residual control periods.

title: MENTAL PROCESSES AS LEITMOTIF IN THE SUBJECTIVE DYNAMISM REPRESENTATION OF THE NARRATOR IN INÉS DEL ALMA MÍA AND IN THE BRAZILIAN TRANSLATION INÊS DE MINHA ALMA

description: ABSTRACT This study aims, from a systemic functional approach (HALLIDAY; MATHIESSEN, 2014), to show both in source text and target text (Brazilian Portuguese) the relevance of MENTAL PROCESSES, taken here as subjective dynamism (HOY, 2017), for the representation of the narrator and protagonist of Inés del alma mía (ALLENDE, 2006), especially when related to the axis of thinking. It also aims to identify the ideational equivalences and shifts in the target text based on the Transitivity model applied to literary translation (CATFORD, 1965; MATTHIESSEN, 2001; HASAN, 1989; RODRIGUES-JÚNIOR; GARCIA de OLIVEIRA, 2015a; RODRIGUES-JÚNIOR; BARBARA, 2013). The data were collected, organized and described by using three tools from the WordSmith Tools 6.0 software: (i) wordlist; (ii) concordance; (iii) and View and Aligner. The analysis procedures concerning Inés's ideational representation and her dynamism was carried out based on the Transitivity model and the concepts of ideational equivalence and shifts (RODRIGUES-JÚNIOR; GARCIA de OLIVEIRA, 2015a), as well as upon the axis of thinking. The data has shown that mental processes were considered relevant resources to represent Inés's subjective dynamism (HOY, 2017). It has also demonstrated that the ideational equivalence has prevailed in the target text, although there were some ideational shifts that have changed her ideational representation.

title: Amazonian dark earths in the fertile floodplains of the Amazon River, Brazil: an example of non-intentional formation of anthropic soils in the Central Amazon region

description: ABSTRACT Amazonian dark earths (ADEs) are fertile soils created by pre-Columbian Amerindian societies of the Amazon Basin. However, it is still not clear whether these soils were produced intentionally to improve infertile Amazonian upland soils or if they resulted from the accumulation of organic matter from sedentary settlements. This study characterizes the ADEs found in the naturally fertile alluvial floodplains of the Amazon River in the Central Brazilian Amazon according to total, exchangeable, and available contents of elements and organic carbon in soil profiles. ADEs contained higher levels of available elements and total P, Ca, Zn, and Cu. High total Cr, Ni, Co, and V content in these soils indicate that mafic minerals contributed to their composition, while higher contents of P, Zn, Ba, and Sr indicate anthropic enrichment. The presence of ADEs in floodplain areas strongly indicates non-intentional anthropic fertilization of the alluvial soils, which naturally contain levels of P, Ca, Zn, and Cu higher than those needed to cultivate common plants. The presence of archaeological sites in the floodplains also shows that pre-Columbian populations lived in these regions as well as on bluffs above the Amazon River.

title: Allelopathic Effect of Lotus and Arrowhead Weed on Wheat, Wild Oat and Milkthistle Germination

description: ABSTRACT: An experiment was conducted to investigate the allelopathic effects of lotus (Nelumbo nucifera Gaertn.) and arrowhead (Sagittaria sagittifolia (Brummitt & Powell): L.) on seed germination of wheat and two associated weeds, namely, wild oat (Avena fatua L.) and milk thistle (Silybum marianum (L.) Gaertn.). The experiment was laid out in a Completely Randomized Design during May, 2014. Dried biomasses of lotus and arrowhead leaves were soaked in distilled water for 48 hrs for extract preparation. The extracts were applied at a rate of 5 and 10% concentrations to the seeds of wheat, wild oat and milk thistle at 25 °C in 10 cm wide Petri plates. A control treatment where only distilled water was applied to the seeds, was included for comparison. Data were recorded on germination (%), shoot length (cm), shoot and root fresh weights (g). The results revealed that 10% lotus extract reduced germination of wild oat (0.00%) and milk thistle (13.3%) but comparatively enhanced that of wheat (20%). By contrast, arrowhead totally inhibited germination of wheat and wild oat as compared to milk thistle (16.66%). Similarly, 10% lotus extract favored shoot length and root weight of wheat and milk thistle, whereas 100% inhibited wild oat. By comparison, arrowhead completely inhibited shoot length and root weight of wheat and wild oat at 10% conc. and enhanced milkthistle (3.00 cm and 3 g). A higher lotus extract conc. affected wild oat more than wheat and milkthistle, while arrowhead weed affected almost all test species. In conclusion, these aquatic weeds can be used as mulch in wheat in nearby fields of the infested aquatic water bodies for wild oat control, weed biomass disposal and nutrient addition to the soil.
