title: Prediction of live weight in beef heifers using a body volume formula

description: ABSTRACT The objective of this study was to develop and evaluate linear, quadratic, and allometric models to predict live weight (LW) using the body volume formula (BV) in crossbred heifers raised in southeastern Mexico. The LW (426.25±117.49kg) and BV (338.05±95.38 dm3) were measured in 360 heifers aged between 3 and 30 months. Linear and non-linear regression were used to construct prediction models. The goodness-of-fit of the models was evaluated using the Akaike Information Criterion (AIC), Bayesian Information Criterion (BIC), coefficient of determination (R2), mean squared error (MSE), and root MSE (RMSE). In addition, the developed models were evaluated through cross-validation (k-folds). The ability of the fitted models to predict the observed values was evaluated based on the RMSEP, R2, and mean absolute error (MAE). The quadratic model had the lowest values of AIC (2688.39) and BIC (2700.05). On the other hand, the linear model showed the lowest values of MSE (7954.74) and RMSE (89.19), and the highest values of AIC (2709.70) and BIC (2717.51). Despite this, all models presented the same R2 value (0.87). The cross-validation (k-folds) evaluation of fit showed that the quadratic model had better values of MSEP (41.49), R2 (0.85), and MAE (31.95). We recommend the quadratic model to predictive of the crossbred beef heifers' live weight using the body volume as the predictor.

title: Clinical parameters and calf liveweight of Nellore breeders supplemented or not with phosphorus, during pregnancy and lactation - a case study

description: ABSTRACT The aim of this case study was to evaluate the clinical and productive data of Nellore cows during pregnancy and lactation, supplemented or not with P. Ninety-five pregnant heifers were divided into two groups (G40 and G0). Until the date of calving animals from G40 received a mineral mixture composed of 224g of Na and 40g of P/kg, and G0 received only NaCl. After calving heifers were divided into four treatments: from G40, 28 first-calf cows continued to receive the mineral mixture containing 224g of Na and 40g of P/kg (group 40/40) and 12 started to receive only NaCl (group 40/0); from G0, 26 continued to receive only NaCl (group 0/0) and 15 started to receive a mixture containing 224g of Na and 40g of P/kg (group 0/40). In the second experimental phase, 205 multiparous cows were divided into two groups: G1 (40/40) consisting of 40 cows, receiving a mineral mixture containing 244g of Na and 40g/P per kg, during pregnancy and lactation, and group 2 (0/0) formed by 165 cows, which were supplemented only with NaCl. In both experiments, whether in pregnant or lactating breeders, there was not any sign of P deficiency or differences in calves LW at 120 and 210 days.

title: SERVICE LEARNING AS A MODEL FOR LINGUISTIC DEVELOPMENT OF STUDENTS OF SPANISH AS A HERITAGE LANGUAGE AND AS A FOREING LANGUAGE

description: ABSTRACT This article presents an investigation carried out to study the linguistic development of students from a Spanish Language class. The community service learning (from now on, due to its initials in English, SL) methodology is used. The students of Spanish as heritage language learners (from now on, due to its initials in English, HLLs) and students of Spanish as a foreign language (from now on, due to its initials in English, FLLs) participated in SL in which they translated educational and medical materials from English into Spanish. The first objective was to determine whether SL affects vocabulary development and to what extent students’ prior knowledge benefits their linguistic development. The second objective was to observe the intrinsic motivation of the students. This research includes eight FLLs participants and eight HLLs participants who, as an assignment of the Spanish language course, translated the materials. Two diagnostic tests were administered in order to analyze the results. A qualitative analysis shows that the intrinsic motivation of the students underwent favorable changes. Quantitative analysis indicates that vocabulary development increases due to connections between previous and new language skills. This research concludes by highlighting the results; among the results it can be observed the development of the linguistic aptitude, of the vocabulary, and the sense of belonging to the Hispanics community from part of the students.

title: Efficient Encapsulation and Controlled Release of N,N-Diethyl-3-methylbenzamide (DEET) from Oil-in-Water Emulsions Stabilized by Cationic Nanocellulose and Silica Nanoparticles

description: Oil-in-water emulsions containing N,N-diethyl-3-methylbenzamide (DEET) were developed aiming to extend the sustained release of the active compound, by using two oppositely charged nanomaterials, namely silica nanoparticles (SiNP) and cationic cellulose nanofibrils (CCNF), as stabilizers, and a mixture of food-grade nonionic surfactants to avoid precipitation by electrostatic aggregation. The formulations were stable for more than four months at room temperature, and strongly resistant to destabilization upon centrifugal and thermal stress. The results were correlated with the effect of SiNP on strengthening the network formation of CCNF in the aqueous phase by electrostatic interactions, which increased the viscosity of the external phase and, hence, emulsion stability. There was a significant size reduction of the internal oil phase containing DEET in the presence of CCNF, which was attributed to the increased viscosity in the external aqueous phase, as well as to interfacial stabilization. The combined action of CCNF and unmodified SiNP in the stabilization of the DEET-containing oil phase significantly decreased the release rate of the active compound, compared to non-emulsified DEET. Moreover, in the emulsions containing the CCNF/SiNP mixture there was a more sustained release for the period of 6 h, demonstrating the potential of these formulations for extended protection.

title: Psychometric Properties of the Brazilian Version of the Ambivalence in Psychotherapy Questionnaire (APQ)

description: Abstract High levels of ambivalence are associated with poor outcomes and therapeutic abandonment. The objective of this study was to conduct a cross-cultural adaptation and assessment of the psychometric properties of the Ambivalence in Psychotherapy Questionnaire (APQ). After cultural adaptation of the instrument, we assessed 181 individuals undergoing psychotherapy of different approaches in school clinics and private practices. The APQ was validated regarding internal structure and relationship with external variables. In the confirmatory factor analysis, the model with the best fit was composed of three dimensions: two first-order - Demoralization and Wavering - and one second-order - Ambivalence. The internal consistency was 0.86. In relation to external variables, the APQ correlated moderately with measures of psychological distress (OQ-45- Outcome Questionnaire) (r = 0.65) and motivation to change (URICA- University of Rhode Island Change Assessment): contemplation (r = 0.36) and maintenance (r = 0.37). The results indicated that the Brazilian version of the APQ is a suitable instrument, of quick and easy application.

title: Selection of earliness peanut accessions for genetic improvement in a water-restricted environment

description: ABSTRACT Peanut production is growing annually in Brazil, but with frequent droughts throughout the country, it is necessary to identify an earliness germplasm for the improved environmental adaptation of peanuts. Here, a mini-core collection of peanuts was studied to select germplasms for further use in breeding, with a focus on dry environments. Twelve agronomic traits were adopted and later used in multivariate methods based on hierarchical models (UPGMA) and graphical dispersion (canonical variables), which aimed to identify earliness accession clusters. Statistically significant differences were found for most traits, indicating that there was genetic variability among accessions. Multivariate analyses subsequently revealed coherence in the formation of three clusters, one of which (G3: PI-268-689 and AHK-85-3) combined the most promising accessions for pod production and reproductive efficiency, previously identified through analysis of variance. Therefore, both germplasms are recommended here for use in future breeding studies focused on water-restricted environments.

title: Comparison of Surgical Techniques Used in Ventricular Septal Defect Closure

description: ABSTRACT Introduction: We compared transatrial closure, tricuspid valve septal detachment, and tricuspid valve chordal detachment techniques for ventricular septal defect (VSD) closure. Methods: Patients who had VSD closure with three different techniques in our clinic between September 2016 and December 2020 were retrospectively reviewed. A total of 117 patients were included in the study. The patients were divided into three groups: group 1, classical transatrial closure; group 2, closure with tricuspid valve septal detachment; and group 3, closure with tricuspid valve chordal detachment. The groups were evaluated by serial transthoracic echocardiography (preoperative, postoperative 1st day, postoperative 1st month). Cardiac rhythm checks and recordings were performed. Results: No residual VSD was observed in early or late periods in any of the groups whose VSD closure was performed with the three different techniques. No severe tricuspid regurgitation (TR) was detected during the early and late postoperative periods of all operating procedures. When the groups were compared in terms of early/late TR after the operation (without TR+trace amount of TR and mild TR+moderate TR were compared), no statistically significant difference was found (P&gt;0,05; P=0,969 and P&gt;0,05; P=0,502). Conclusion: In this study, we found no statistically significant difference between three VSD closure techniques in terms of early TR, late TR, residual VSD, and permanent atrioventricular complete block during postoperative period. We hope that our results will be supported by the results of researches that are being made about this subject in large series.

title: ORBITAL REMOTE SENSING FOR THE MANAGEMENT OF AREAS IRRIGATED WITH A CENTRAL PIVOT SYSTEM

description: ABSTRACT Irrigated agriculture is considered one of the most important techniques for agricultural production in the world, despite being the sector that uses water resources the most. Thus, technological advances have been constantly developed and applied in the sector as a way to improve water management and reduce its consumption, considering that some cultures are affected by economic costs and feasibilities of production, because the water cost has increased significantly in recent years. Remote sensing is a technology that has provided good results for estimating evapotranspiration (ETr) in producing areas, enabling more efficient irrigation management for low costs. This study aimed to answer the question about how the generation of irrigation management zones (IMZs) can be used to optimize water use and improve irrigation systems and which ETr models are better for it. Three ETr estimation models (Surface Energy Balance Algorithm for Land [SEBAL], Mapping Evapotranspiration at High Resolution and with Internalized Calibration [METRIC] and Simple Algorithm for Evapotranspiration Retrieving [SAFER]) were used to design IMZs in center pivot cultivated with cotton. The design of IMZs with ETr data proved to be a viable alternative, making it possible to improve water management in irrigated systems, reducing costs with viability irrigation for cotton and others cultures. The METRIC method displayed the greatest ease in obtaining the data used in the ETr estimation for generating the IMZs.
