title: Syndromic craniosynostosis: neuropsycholinguistic abilities and imaging analysis of the central nervous system

description: ABSTRACT Objective: To characterize patients with syndromic craniosynostosis with respect to their neuropsycholinguistic abilities and to present these findings together with the brain abnormalities. Methods: Eighteen patients with a diagnosis of syndromic craniosynostosis were studied. Eight patients had Apert syndrome and 10 had Crouzon syndrome. They were submitted to phonological evaluation, neuropsychological evaluation and magnetic resonance imaging of the brain. The phonological evaluation was done by behavioral observation of the language, the Peabody test, Token test and a school achievement test. The neuropsychological evaluation included the WISC III and WAIS tests. Results: Abnormalities in language abilities were observed and the school achievement test showed abnormalities in 66.67% of the patients. A normal intelligence quotient was observed in 39.3% of the patients, and congenital abnormalities of the central nervous system were observed in 46.4% of the patients. Conclusion: Abnormalities of language abilities were observed in the majority of patients with syndromic craniosynostosis, and low cognitive performance was also observed.

title: Heading of shoots and hand thinning of flowers and fruits on 'BRS Kampai' peach trees

description: Abstract: The objective of this work was to evaluate the effect of shoot heading and of hand thinning in different development stages of flowers and fruits on the fruit production and quality of 'BRS Kampai' peach (Prunus persica) trees. The experiment was performed during three crop years, under the conditions of the “Depressão Central” region in the state of Rio Grande do Sul, Brazil, and the treatments were: T1, heading of half of the mixed shoot; T2, heading of one third of the mixed shoot; T3, flower thinning in the pink bud stage; T4, thinning at full bloom; T5, thinning of fruit with 5 mm; T6, thinning of fruit with 20 mm; and T7, no thinning or heading (control). Fruit production and quality were evaluated. Plants with no thinning were more productive, but showed high frequency of fruits with a diameter smaller than 60 mm. Shoot heading reduced production per tree and resulted in small-sized fruit. Thinning time did not affect production, and fruit size was greater when thinning was performed at the bloom stage. 'BRS Kampai' peach trees can be thinned starting at bloom, which provides greater fruit size, with no production loss.

title: Multiple linear regression and random forest to predict and map soil properties using data from portable X-ray fluorescence spectrometer (pXRF)

description: ABSTRACT Determination of soil properties helps in the correct management of soil fertility. The portable X-ray fluorescence spectrometer (pXRF) has been recently adopted to determine total chemical element contents in soils, allowing soil property inferences. However, these studies are still scarce in Brazil and other countries. The objectives of this work were to predict soil properties using pXRF data, comparing stepwise multiple linear regression (SMLR) and random forest (RF) methods, as well as mapping and validating soil properties. 120 soil samples were collected at three depths and submitted to laboratory analyses. pXRF was used in the samples and total element contents were determined. From pXRF data, SMLR and RF were used to predict soil laboratory results, reflecting soil properties, and the models were validated. The best method was used to spatialize soil properties. Using SMLR, models had high values of R² (≥0.8), however the highest accuracy was obtained in RF modeling. Exchangeable Ca, Al, Mg, potential and effective cation exchange capacity, soil organic matter, pH, and base saturation had adequate adjustment and accurate predictions with RF. Eight out of the 10 soil properties predicted by RF using pXRF data had CaO as the most important variable helping predictions, followed by P2O5, Zn and Cr. Maps generated using RF from pXRF data had high accuracy for six soil properties, reaching R2 up to 0.83. pXRF in association with RF can be used to predict soil properties with high accuracy at low cost and time, besides providing variables aiding digital soil mapping.

title: ECONOMIC STRUCTURE AND SUB-NATIONAL POLICY IN ARGENTINA

description: This article aims to contribute to the debate on subnational state-society relations, focusing specifically on the Argentine case. To this end, we develop two specific objectives. First, we develop a theoretical and conceptual argument about the importance of studying the diversity of economic structures that exist at the subnational level, in order to understand the impact that they have on state-society relations. Second, we propose an analytic framework to classify the Argentine provinces according to their economic structure. This classification is based on three variables: the strength of the private sector in the provincial economy, the relative weight of the subnational state in the economy, and the type of production that predominates. On the basis of this classification, in the conclusions we hypothesize about the incentives that economic actors have to establish varying types of relations with the provincial state.

title: Performance, Carcass Traits and Economic Availability of Muscovy Ducks Fed on Different Nutritional Plans in Different Housing Densities

description: ABSTRACT The present study aimed to evaluate ducks on performance, carcass traits and economic availability, fed on different phases of nutritional plans and in different housing densities. Two hundred and forty Muscovy ducks of creole lineage were used, distributed in boxes with water and food ad libitum. The experimental design was completely randomized in a factorial arrangement of 3x2 with three nutritional plans (3, 4 and 5 phases) and two housing densities (2 and 3 birds/m2) with four replicates. The ducks had weekly performance evaluations, and after 90 days, four birds in each treatment were slaughtered for evaluation of carcass traits. Differences (p&lt;0.05) were observed on performance, carcass traits and economic analysis. The nutritional plans with 3 phases showed better results for feed intake and weight gain, as well as provided lower total cost production and higher operating profit. Ducks in higher densities showed smaller feed intake, weight gain, higher pro-ventricle weight and better results for total meet production, crude income and operating profit. In summary, nutritional plans with reduced phases (3 phases) and extensions of energy-protein relationships showed better results for ducks on performance and carcass traits in densities of 3 birds/m². More studies are necessary to determine other nutritional requirements for ducks in housing for a better nutritional and management control.

title: Microbiological, Physicochemical, and Histological Analyses of Broiler Carcasses with Cachexia

description: ABSTRACT Broiler carcasses presenting cachexia, as determined by the federal inspection agency, were submitted to microbiological, physicochemical, and histological analyses. Over a 2-month period, 278 carcasses from straight-run flocks of 43- to 48-d-old Cobb broilers from two different farms were condemned due to cachexia and subjected to gross examination in the final inspection sector. Out of the 278 carcasses, 131 did not present any gross signs of infection, and were submitted to microbiological analyses (n=83), physicochemical analyses (n=28), and viscera and muscle samples of 20 carcasses were evaluated by histology. The microbiological results of cachectic carcasses complied with the current legislation on the consumption of fresh poultry meat. Lower lipid and higher protein, moisture, and volatile matter contents, and higher pH (p&lt;0.05) were determined in the cachectic than in the control carcasses from a same flock, but no ash content differences. All carcasses were negative for hydrogen sulfide. The histological analysis showed that65% of the cachectic carcasses did not have any muscle injury, 20% showed mild hyalinization and 15% moderate proliferation of fibrous connective tissue. The findings of this study indicate the importance of further technical and scientific studies on the utilization of cachectic broiler carcasses for the manufacture of edible products, rather than whole carcasses rendering, thereby preventing the resulting economic losses.

title: Who Leads Your Opinion? Opinion Leaders’ Influence on Virtual Engagement

description: Abstract Digital influencers are virtual opinion leaders that represent an alternative for companies targeting to advertise at the community surrounding these individuals. These individuals expand concepts of consolidated theories that examine the process of innovation diffusion and the flow of communication between opinion leaders and followers. Research about the power of these opinion leaders have in virtual social networks is still in its early stages and an obvious gap is how to measure the influence these opinion leaders have on engagement. This article details an approach that measures this influence on Instagram by analyzing all posts published in 2015 on four widely followed public profiles. Three hypotheses evaluated differences in engagement metrics provoked by individual (people) and institutional (institutional entities) opinion leaders. The two-stage least squares regression models confirmed the hypotheses that individual opinion leaders intensify engagement: postings on individual profiles produce significantly more likes, comments and word of mouth than posts on institutional profiles. Results from the empirical models are particularly relevant to companies seeking to raise interaction levels with their target audience on virtual social networks.

title: STUDY OF SECONDARY OSSIFICATION CENTERS OF THE ELBOW IN THE BRAZILIAN POPULATION

description: ABSTRACT Objective: To evaluate the age in which the secondary ossification centers of the elbow appear and fuse in the Brazilian population. Methods: Nearly thirty radiographs were randomly selected for each age group from 0 to 18 years, with a total of 544 radiographs from 439 patients, between 2010 and 2015, without abnormalities secondary to trauma, metabolic or bone tumor diseases. Radiographs were retrospectively evaluated by two blind and independent observers, according to the presence or not of the ossification centers, and the fusion between them. Results: The age interval of appearance and fusion were, respectively: capitulum (0 to 1 year; 10 to 15 years), radius head (2 to 6 year; 12 to 16 years), medial epicondyle (2 to 8 years; 13 to 17 years), trochlea (5 to 11 years; 10 to 18 years), olecranon (6 to 11 years; 13 to 16 years), e lateral epicondyle (8 to 13 years; 12 to 16 years). Appearance and fusion were earlier in girls compared to boys (exception to capitulum and radius head). Conclusion: The chronological order was similar to the literature. For girls, the radius head and medial epicondyle appeared simultaneously. There was a tendency of the olecranon center to appear before the trochlea for both sexes. Level of Evidence III, Diagnostic Study.

title: The saga of Payaré Akrãtikatêjê against the Brazilian State in the context of the construction of the Tucuruí hydroelectric dam

description: Abstract This article is the result of research that was conducted during the year 2011, based on the life history method, here mainly concerning oral history. The result of this research was presented in my graduation monograph, evaluated in the same year, and here revisited in order to tell the story of Payaré Akrãtikatêjê. Indigenous leader Akrãtikatêjê fought a judicial battle for more than thirty years against the Brazilian state to see repaired a historical error of Brazilian justice that denied the indigenous identity to him and his people in the context of the Tucuruí hydroelectric project. With the construction of the hydroelectric dam, the lands of the Akrãtikatêjê people were flooded and the Payaré saga to guarantee the survival rights of his people began.
