title: Morphophysiology and production of West Indian cherry under salt stress and nitrogen-phosphorus-potassium fertilization

description: ABSTRACT The cultivation of West Indian cherry under irrigation with saline water is subjected to harmful effects caused by salt stress. Identifying combinations of nitrogen-phosphorus-potassium fertilization can be a strategy to ensure the expansion of irrigated agriculture. In this context, the objective of this study was to evaluate the morphophysiology and production of the West Indian cherry ‘Flor Branca’ as a function of irrigation with waters of different electrical conductivities and fertilization with nitrogen-phosphorus-potassium combinations. The experiment was conducted in a greenhouse using the randomized block design in a 2 × 10 factorial scheme, corresponding to two values of electrical conductivity of irrigation water (0.6 and 4.0 dS m-1) and ten combinations of fertilization with nitrogen (N), phosphorus (P), and potassium (K): 80-100-100, 100-100-100, 120-100-100, 140-100-100, 100-80-100, 100-120-100, 100-140-100, 100-100-80, 100-100-120, and 100-100-140% of the NPK recommendation, with three replicates. Irrigation with water of 4.0 dS m-1 negatively affected stomatal conductance, average crown diameter, crown volume, and the number of fruits per plant of West Indian cherry cv. Flor Branca. The combination of 100-100-100% NPK increased transpiration, CO2 assimilation rate, and stomatal conductance at 260 days after transplantation. Although the NPK combination of 80-100-100% increased number of fruits, the highest production per plant was obtained under 100-80-100% NPK, regardless of the electrical conductivity of irrigation water.

title: POLITICAL, CONTEXTUAL AND KNOWLEDGE DIMENSIONS OF TEACHER EDUCATION: A PERSPECTIVE IN THE LIGHT OF BAKHTINIAN THOUGHT

description: ABSTRACT: Based on Bakhtinian thought, we developed dimensions of a perspective of counter-hegemonic training of Science teachers. This training perspective, which we call “dialogical-responsible teacher education,” consists of seven dimensions - practical, ethics, aesthetics, investigative, political, contextual, and knowledge. The last three will be developed in this paper. The development of these dimensions was built up from the collating of Bakhtinian Circle texts with texts from the literature on teacher education, tensions, and contrasts, showing insufficiencies and proposing advances concerning the hegemonic training model guided by technical rationality. In this process, formative dimensions emerged that distanced from a prescriptive profile, are constituted as principles that allow rethinking, transforming, giving directions, and structuring formations that break with the hegemonic perspective. We argue that our dimensions make it possible to resignify teacher education regarding the broad understanding of reality, criticality, teaching autonomy, organicity of training processes, and dialogicity in constructing knowledge.

title: Left Atrial Appendage Volume Predicts Atrial Fibrillation Recurrence after Radiofrequency Catheter Ablation: A Meta-Analysis

description: Abstract Background The influence of left atrial appendage volume (LAAV) on the recurrence of atrial fibrillation (AF) following radiofrequency catheter ablation remains unclear. Objectives We performed a meta-analysis to assess whether LAAV is an independent predictor of AF recurrence following radiofrequency catheter ablation. Methods The PubMed and the Cochrane Library databases were searched until March 2022 to identify publications evaluating LAAV in association with AF recurrence after radiofrequency catheter ablation. Seven studies that fulfilled the specified criteria of our analysis were found. We used the Newcastle-Ottawa Scale to evaluate the quality of the studies. The pooled effects were evaluated depending on standardized mean differences (SMDs) or hazard ratios (HRs) with 95% confidence intervals (CIs). P values &lt; 0.05 were considered statistically significant. Results A total of 1017 patients from 7 cohort studies with a mean follow-up 16.3 months were included in the meta-analysis. Data from 6 studies (943 subjects) comparing LAAV showed that the baseline LAAV was significantly higher in patients with AF recurrence compared to those without AF (SMD: −0.63; 95% CI: −0.89 to −0,37; all p values &lt; 0.05; I2= 62.6%). Moreover, higher LAAV was independently associated with a significantly higher risk of AF recurrence after radiofrequency catheter ablation (HR: 1.10; 95% CI: 1.02 to 1.18). Conclusions The meta-analysis showed that there is a significant correlation between LAAV and AF recurrence after radiofrequency catheter ablation, and the role of LAAV in AF patients should not be ignored in clinical practice.

title: Determination of the physiological quality of corn seeds by infrared equipment

description: Abstract: The use of infrared equipment to evaluate the physiological quality of seeds has become an extremely important technique for the operation, since it is not destructive to the seed and is safe for the operator. The experiment was divided into two stages, in the first, the controlled deterioration curve was carried out, and in the second stage, the validation of the NIR XDS process was carried out, through modeling for classification of the lots. The technique used for controlled deterioration proved to be efficient to show that with a higher band ratio index, the spectrum has a greater amplitude and lower physiological potential, the opposite is also valid, when the band index is smaller, the spectrum amplitude is smaller and higher values of germination and vigor were observed. For the second stage, it was concluded that spectra generated by NIR XDS equipment can be used quickly for decision making on corn seed samples, considering a binary classification for the parameters of germination and vigor according to the approval and disapproval values of lots considered in this study.

title: Association of bone morphogenetic protein 15 and growth differentiation factor 9 with litter size in livestock: a review study

description: ABSTRACT. Litter size is one of the crucial factors in livestock production and is of high economic value, which is affected by ovulation rate, hormones, and growth factors. Growth factors play a multifaceted role in reproductive physiology. This review aims to investigate the association of bone morphogenetic protein 15 (BMP15) and growth differentiation factor 9 (GDF9) with litter size in livestock. The transforming growth factor β (TGF- β) superfamily includes more than 34 members; GDF9 and BMP15 are among the most significant factors for regulating fertility and litter size in most livestock species. Ovarian follicles release BMP15 and GDF9 that are involved in the maturation of primary follicles into the basal form, proliferation of granulosa and theca cells, steroidogenesis, ovulation, and formation of the corpus luteum. Besides, these factors are highly expressed in oocytes and are necessary for female fertility and multiple ovulation in several livestock species. Animals with two inactive copies of these factors are sterile, while those with one inactive copy are fertile. Thus, the present review provides valuable information on the association of BMP15 and GDF9 with litter size in livestock that can be used as biological markers of multiple ovulation or for improving fertility in livestock.

title: Literatura, formação e educação na obra de Antonio Candido: a humanização do homem

description: ABSTRACT As literature obtained primacy in Brazil’s cultural and intellectual life and occupies a prominent place in the work of Antonio Candido, in this article, based on his reflections, we strive to show some discussions on the contribution of literature to the formation and humanization of man. Because, on his journey, the critic also turned his attention to education, a less relevant aspect of his production when compared to others, such literary criticism. In this sense, it would not be an exaggeration to say that Candido provides important contributions, scholarly underpinnings, and theoretical tools to rethink how we have conceived the educational process and historically constructed the education and the university in Brazil.

title: VOLTAGE REGULATION IN RURAL NETWORKS WITH DISTRIBUTED GENERATION

description: ABSTRACT The increase in distributed generation (DG) interferes with the energy distribution system, which may present low voltages due to voltage drops and high voltages due to the insertion of distributed generation, resulting from renewable energy sources in rural areas. These voltage levels must be controlled to comply with the limits imposed by the distribution rules and procedures (PRODIST). This study aims to evaluate the voltage rise caused by DG, simulating three DG insertion scenarios, as well as simulate strategies to correct these voltage levels, such as the limitation of the active power supply, the reactive supply by the consumer and the utility, and the installation of on-load tap changers. The simulations were performed using the MATLAB® program, more specifically the PSAT toolbox. Correction techniques were simulated using the active power supply limitation method, the reactive power supply method by consumers, and the voltage regulator process once the voltage rise effect was identified. The first two proved to be ineffective in this case, while the last one meets the voltage levels required by the National Electric Energy Agency.

title: POTENTIAL USE OF PALM OIL AND COCOA WASTE BIOMASSES AS SOURCES OF ENERGY GENERATION BY GASIFICATION SYSTEM IN THE STATE OF PARÁ, BRAZIL

description: ABSTRACT Regional development in the state of Pará (Brazil) continues to be limited by lack of access to energy. This is a problem that is widespread in several rural communities and agricultural regions. Therefore, this study aimed to analyze the potential use of palm oil and cocoa processing waste biomass, which are abundant in the state and whose energy capacities can be used to generate electricity in biomass gasification plants. To do so, a literature review on elementary and calorific value analysis of palm oil (empty fruit bunches, fibers, kernel shell and cake, trunks, and others) and cocoa (pod husks) were conducted. The findings have shown that both waste biomass materials have satisfactory energetic characteristics for use in gasification plants. Thus, palm oil and cocoa processing waste biomasses are alternative energy sources for producers of these fruits in upstate Pará, enabling the development of the region.

title: Fish functional trophic groups in headwater karst streams from the Upper Paraguay River basin

description: Abstract Data obtained by direct observation of organisms in their natural habitats can provide valuable contributions regarding intra- and inter-specific interactions, as well as spatial distribution and trophic relationships. However, relatively few such data are available for the Neotropical ichthyofauna relative to the great species diversity of this region. We present data on the ichthyofauna in karst environments of the Serra da Bodoquena, Upper Paraguay River basin regarding their categorization into functional trophic groups. We used direct observations that focused on the most frequent feeding tactics and their spatial (vertical and horizontal) distribution in the channel. We observed 83 fish species in 17 functional trophic groups. The greatest species richness was concentrated in the Characidae and Loricariidae in the categories Diurnal Backwater Drift Feeders and Grazers, respectively. Regarding horizontal depth stratification, we found a positive relationship between the association of small fish with the shallow marginal habitats. This work represents a contribution to a region known for its high tourist potential and to the important diversity of the entire ichthyofauna of the Upper Paraguay basin region that requires proper conservation strategies for sustaining these species.
