title: The Role of Training in Shaping Pre-Service Teacher Cognition Related to L2 Pronunciation

description: Abstract This study analyzed changes in the pronunciation-related cognitions of undergraduate TESL students from two Canadian universities during their first term in their programs. The students from one university attended a 13-week course in phonology and pronunciation teaching, while those from the other university received no specific training in pronunciation. Towards the end of the term, the participants who received specialized training had more favorable views of explicit pronunciation teaching and became more confident in their ability to teach pronunciation than the comparison group. The course also helped the participants increase in awareness of their own speech and limitations. The findings point to the importance of native-nonnative speaker interactions in shaping cognitions and suggest that more support to nonnative-speaking TESL students and more training in the use of communicative activities would be helpful.

title: Retrieving the object: found footage volumetric extrapolations

description: Abstract This paper briefly examines the history and the operational underpinnings of forms of volumetric reconstruction based on the capture of visual data, particularly photogrammetry. Photogrammetry is one of the chief techniques currently employed in the production of virtual replicas for heritage conservation. The computational realism resulting from this process induces us to believe that it is possible to recover the totality of an object from its media traces. We mean to challenge this technological promise by referring to artistic projects that explore the idiosyncrasies of photogrammetric models.

title: CHARACTERIZATION OF YELLOW LATOSOLS (OXISOLS) OF SERRA DO QUILOMBO, IN PIAUÍ STATE SAVANNA WOODLANDS - BRAZIL

description: ABSTRACT The savanna woodlands of Piauí state has great economic importance since it is an area for agricultural expansion, being the fourth most important of Brazil and the first from Brazilian Northeastern. The area accounts for 5.9% of the Brazilian savanna woodlands and 36.9% of the Northeastern savanna, covering 46% of the Piauí state area, in a total of 11.5 million hectares. The goal of this research was to study pedoenvironments of Serra do Quilombo region, which is in Piauí state savanna, as well as identifying existing soil classes, according to the Brazilian System of Soil Classification - SiBCS. Soil identification consisted in characterizing soil profiles along a transect, assessing in-field conditions and collecting soil samples, in areas of native vegetation. The samples were gathered from three distinct points, being two at the edges and one at the center of the plateau. Soil analyses were carried out with samples collected from each horizon through trench digging up to a 2-m depth. Morphological, physical, chemical and mineralogical characterizations were performed for each soil profile, along with an evaluation of the effect of pedogenic factors on their formation and development. All soils under study were formed with source materials of the same geological formation; however, each rock has a distinct contribution to the process, involving sandstones and shales. The characteristics observed in the soil from Serra do Quilombo have no difference from the pattern found in the Brazilian plateaus, and soil profiles were classified as dystrophic clayey Yellow Latosols (Oxisols), according to the SiBCS.

title: A state for the contemporary children’s poetry: reflections based on PNBE

description: abstract Government initiatives meant to promote reading, such as the National School Library Program (PNBE - Programa Nacional Biblioteca da Escola), influence the Brazilian publishing market, determining what book titles are offered to schools that meet the demands of such a policy and, consequently, contribute to the creation of a Brazilian children's and youth literary state. In order to analyze Brazilian children's poetry, this essay uses selected poetic works from the PNBE 2010 collection. Four poems from four different books were analyzed to discuss the poetic composition in Brazilian children's poetry selected by PNBE. The article analyzes the identity of Brazilian children's poetry in contemporary society, considering the government policy, and shows that the poetic texts tend to invite the young reader to substantiate the interactive and, at the same time, contemplative nature of poetry.

title: MYCORRHIZATION STIMULANT IN SOYBEAN ASSOCIATED WITH PHOSPHATE FERTILIZATION IN OXISOLS

description: ABSTRACT The use of stimulants in the establishment of arbuscular mycorrhizal fungi has great potential in contributing to P uptake by plants. This study aimed to evaluate the effect of isoflavonoid formononetin as mycorrhization stimulant on soybean associated with phosphate fertilizer in Oxisols with intermediate (OPi) and low (OPl) phosphorus availability, in the Cerrado region of Piauí. The experiment in each soil consisted of randomized blocks design in a 4×4 factorial scheme, with four replications. The treatments comprised of four phosphorus doses (0, 26.66, 40 and 80 kg ha-1 P2O5), and four isoflavonoid formononetin doses (0, 0.5, 0.9 and 1.8 g kg-1 soybean seeds). The variables evaluated were soybean growth, yield, nodulation and mycorrhizal colonization rate. With the exception of mycorrhizal colonization rate in OPi, plant height and number of pods per plant in OPl, the other variables were not affected by the application of isoflavonoid formononetin, in both soils. Yield linearly increased with increase in the phosphorus doses in OPl, and presented agronomic efficiency of ~15 kg ha-1 grain for each kg ha-1 P2O5 applied to the soil.

title: Analysis of water leached from soil treated with leachate from plant biomass ash

description: Abstract This work analyzed water leached from soil treated with leachate from plant biomass ash. The ash was generated by industrial boilers used in the pulp and paper industry. Experiments were carried out in columns filled with soil, and the ash was then added to the soil to simulate field conditions. The ash was applied at 30 and 60 tons per hectare rate. The simulated rainwater was prepared for three scenarios: pH 3.0, 6.5 and 8.0. Each leaching experiment simulated an annual precipitation of 2,045 mm. The results showed that the parameter that demands more attention is aluminum concentration. In this context, in acidic conditions (pH 3.0) and with a significant amount of ash added (60 tons per hectare), the level of aluminum may reach the maximum level for drinking water. Despite the potential impact of aluminum, the use of ash from plant biomass in soil for agricultural purposes may serve as an alternative strategy for disposal of this waste.

title: Kinetics of ruminal passage rate of particles of signal grass silage, maize and intercropped

description: The purpose of this study was to evaluate the kinetics of ruminal passage rate of particles from the subsequent associations: corn and signal grass; corn, signal grass and Calopogônio; corn, signal grass and Macrotiloma; and corn, signal grass and Estilosantes. It was used four crossbred holstein-zebu cattle with the rumen tubed in order to determine the the kinetics of ruminal passage rate of particles. The feces were collected at the times zero (immediately after addition of fibers complexed with chromium), 1, 2, 4, 6, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48, 56 , 64, 72, 80, 88, 96, 120, 132, 144 and 192 hours. The profile parameters of passage rate estimative were adjusted according to robust regression procedures. The average time of particles retention in the raft (ATPR1); the average time in the rumen liquid phase (ATRLP2) and the average time of total ruminal retention (ATTRR) were adjusted for the passage kinetics and estimated with the NLIN procedure of SAS. From the observed results, may be suggested that the transference rate λ has an inverse behavior to the escape rate κ, the τ average values, the average retention time and average particles retention time in the rumen liquid phase (ATRLP2) were not statistically different. The feed characteristics after the raft escape and reach to ATRLP2, were very similar; (ATTRR), related to treatments, were not statistically different (P&lt;0,05). There were observed small TMRR numerical differences in different foods. The corn and signal grass; corn, signal grass and calopogônio; corn, signal grass and macrotiloma, corn, signal grass and estilosantes silage fibers had similar rates ofλ, k, ATPR1, ATRLP2 and ATTRR. Therefore, the the kinetics of ruminal passage rate of particles is similar. Thus, the choice of the system should be based on other factors, such as viability of the management ease and silage cost.

title: Organic carbon simulation in polluted rivers: applicability in water quality planning and management

description: ABSTRACT The main goal of this paper was to develop and evaluate the applicability of an organic carbon simulation model to simulate the water quality in polluted rivers. The methodological approach is based on the hypothesis that different fractions of organic carbon, such as particulate, dissolved, labile and refractory, can differently impact in the oxygen depletion due its origin and composition, and. The study was conducted at Iguassu River, located in Upper Iguassu Watershed, with a quantitative and qualitative monitoring of organic carbon fractions, the model and the automatic calibration routine development. The model was implemented in Excel spreadsheet and VBA language, considering a one-dimensional and permanent flow. Multiple diffuse and point sources can be considered during the simulation. The calibration is based on Particle Swarm Optimization algorithm, with 6 control stations in 107 km river length. The case study was developed at Iguassu River, located in a high urbanized basin in Curitiba-PR, an area about 3.000 km2 with approximately 3 million people. The results indicated that the current approach considering distinct organic carbon fractions simulations have potential to be applied in water resources planning and management models.

title: Two-dimensional Determination of the Decision Boundary for a Radar Detection Method in the Moment Space

description: ABSTRACT: The radar detection with decision making in the moments space (DRACEC method) is based on a statistical analysis to determine the boundary between the background (absent target) and the anomaly (present target) classes. In this article, the boundary is taken as an ellipse and is calculated for two dimensions, emphasizing its geometric interpretation. The procedures to establish the shape, location, and size of the ellipse are highlighted, guaranteeing the probability of false alarm by applying the Neyman-Pearson criterion. The proposal establishes a methodology for calculation of the boundary when it is required to use the moments directly as a sufficient decision statistic.

title: An Investigation on Surface Roughness and Tool Wear in Turning Operation of Inconel 718

description: ABSTRACT: This paper investigates the influences of three different input parameters, such as feed rate, insert nose radius, and insert coating methods, in the turning operation of Inconel 718. The coating methods were selected as medium temperature chemical vapor deposition (MT-CVD) and physical vapor deposition (PVD) and in addition to coating methods, the role of various coating materials was discussed since the inserts were coated with multi-layers of TiCN/Al2O3/TiN and single-layer of TiAlN on carbide substrates. The results were discussed in terms of wear behavior of cutting tools and surface quality of the workpiece, which is indicated by surface roughness. A full factorial experimental design was employed in the present work and the results were evaluated using main effects plots. Furthermore, the analysis of variance (ANOVA) method was applied to specify both reactive and non-reactive effects of experimental parameter reactions. The results showed that surface roughness is reduced using low feed rates and large nosed inserts in the operations. Furthermore, TiAlN-coated inserts with PVD method provided better surface finish than with MT-CVD method. It was also found that surface roughness increases as the wear rate of inserts increases.
