title: Performance of cobia grown in brackish water and fed with different feeding rates

description: Abstract: The objective of this work was to evaluate different feeding rates on the productive performance of cobia (Rachycentron canadum) grown in brackish waters. For the experiment, 1,600 juveniles were distributed in 16 enclosures installed in an estuarine pond. Four different feeding rates were evaluated: 1, 3, 5, and 7% live weight (LW) per day. The following performance parameters were assessed: survival, final biomass, specific growth rate, daily weight gain, apparent feed conversion, protein efficiency rate, lipid efficiency rate, and hepatosomatic index. Survival was greater than 80% at all feeding rates. The most efficient feed conversion rate was obtained with the feeding rate of 5% LW per day, which also resulted in better values for the hepatosomatic index. The rate of 5% LW per day provides a better productive performance for cobia in brackish waters.

title: Nitrification of yellow waters in bed percolating of sand

description: ABSTRACT Ecological sanitation awares about the importance of a more efficient water reuse and the use of decentralized wastewater treatment systems. This paper describes the results of yellow waters’ nitrification in a biological reactor made up of simple materials, like sand as support material, aiming to make this liquid waste available for the use of mineralized nitrogen in sustainable agriculture. The experimental system was monitored through pH, dissolved oxygen (DO), total alkalinity (ALK), chemical oxygen demand (COD), total Kjeldahl nitrogen (TKN), ammonia nitrogen (AN), nitrite (NO- 2) and nitrate (NO- 3). The system showed good removal of organic matter and excellent conversion of nitrogen to nitrite and nitrate, with efficiency of transformation of TKN to nitrate of about 93%.

title: Human virome in nasopharynx and tracheal secretion samples

description: BACKGROUND In Brazil the implementation of the Sentinel Surveillance System of Influenza began in 2000. Central public health laboratories use reverse transcription-quantitative polymerase chain reaction (RT-qPCR) for diagnosis of respiratory viruses, but this protocol identifies only specific targets, resulted in inconclusive diagnosis for many samples. Thus, high-throughput sequencing (HTS) would be complementary method in the identification of pathogens in inconclusive samples for RT-qPCR or other specific detection protocols. OBJECTIVES This study aimed to detect unidentified viruses using HTS approach in negative samples of nasopharynx/tracheal secretions by the standard RT-qPCR collected in the Federal District, Brazil. METHODS Nucleic acids were extracted from samples collected in winter period of 2016 and subjected to HTS. The results were confirmed by the multiplex PR21 RT-qPCR, which identifies 21 respiratory pathogens. FINDINGS The main viruses identified by HTS were of families Herpesviridae, Coronaviridae, Parvoviridae and Picornaviridae, with the emphasis on rhinoviruses. The presence of respiratory viruses in the samples was confirmed by the PR21 multiplex RT-qPCR. Coronavirus, enterovirus, bocavirus and rhinovirus were found by multiplex RT-qPCR as well as by HTS analyses. MAIN CONCLUSIONS Wide virus diversity was found by different methodologies and high frequency of rhinovirus occurrence was confirmed in population in winter, showing its relevance for public health.

title: Model improvement for estimating of water turbidity removal efficiency in helical tubular flocculators

description: ABSTRACT Scientific studies have been demonstrating that helical tubular flocculators (HTFs) have high efficiency in floc formation and low hydraulic retention time when compared to flocculators commonly used in water and wastewater treatment. However, its practical application is still limited because there is still a significant demand for advances in the understanding of the relationship between the hydrodynamics of the unit and the flocculation process, as well as for criteria and methodologies in support to the rational design of HTF. In this context, the objective of this study was to propose an improvement in the model of turbidity removal efficiency developed by Oliveira (2014), which takes into account a set of geometric, hydraulic and hydrodynamic parameters relevant to the flocculation process in this type of reactor, by incorporating one of the most representative parameters of flocculation processes, the normal pressure gradient, as one of its independent variables. The development of the work employs computational fluid dynamics (CFD) in the study of 84 HTFs configurations, considering laminar and turbulent flow regimes. As a result, a new model version for estimating water turbidity removal’s efficiency in helical tubular flocculators was obtained, which, in relation to the original version, has a smaller number of independent variables, presents better fit to the experimental data and is simpler from the operational point of view.

title: For the subjects of Momo, tradition is law: government and truth in the organization of Olinda’s Carnival

description: Abstract The Carnival of Olinda is one of the most important events in the city’s cultural life and is one of the largest carnivals in Brazil. As in several carnivals in Brazil, its configuration results from an identity project implemented in the late 1970s, breaking with the model from Recife and resulting in an “authentic” street Carnival. Since then, this new model is defended as a tradition, and its permanence and transformations are inscribed in a complex web of power and resistance, involving from the participants of the revelry to the decisive instances of the celebration. Thus, we investigate how tradition is articulated as an exercise of power in the Carnival of Olinda. To do so, we performed a Foucauldian discourse analysis of the journalistic coverage of four Carnivals of Olinda (1986, 1996, 2006 and 2016). Our findings reveal this tradition as a regime of truth, permeated by tensions involving processes of legitimacy, normalization and resistance.

title: Cattle influence on the population structure of yerba mate (Ilex paraguariensis) in Araucaria Forest

description: ABSTRACT: This study characterized the demography and spatial pattern of a yerba mate (Ilex paraguariensis A.St.-Hil) population covering areas with different use histories (Presence and Absence of Cattle) in a Araucaria Forest. Data collection was performed in three ha, half in each area. The frequency of individuals by height, spatial distribution pattern, diameter distribution (for reproductive individuals) and sexual ratio were evaluated. An inverted “J” pattern predominated, being exclusive to an area with Cattle Presence, a place which presented a lower density of individuals. The predominant spatial distribution pattern was aggregated, and the reproductive individuals have a preferentially random pattern at the shortest distances. Results indicated that cattle presence changes the density of I. paraguariensis individuals and the proportion of individuals in the evaluated demographic classes.

title: Positive emotions in the use of the built space associated with the attributes of biophilic design

description: Abstract Biophilic design has brought nature integration solutions with built-in environments, promoting pleasantness and well-being for users. This paper aims to identify users’ positive emotions associated to the attributes of biophilic design in the evaluation of the built environment of the new Unisinos campus, in Porto Alegre. The proposed method includes a qualitative and a quantitative step, starting with satisfaction survey with the users. A questionnaire was developed to gain more information about the positive emotions elicited by the attributes of the building and the intensity by which those attributes are perceived by the students in interaction with the space. The results demonstrate the positive contribution of the study of design and emotion, as well as biophilic design, to evaluate the built environment.

title: Blood parameters of Angus and Nellore young bulls fed diets with or without forage.

description: ABSTRACT We evaluated blood parameters of Angus and Nellore bulls fed diets with and without forage. Forty animals with initial body weight (BW) of 380±16.2 kg were housed in individual stalls. Eight bulls of each breed were fed a whole shelled corn (WSC) diet [850 g kg−1 of WCS and 150 g kg−1 of a pellet based on soybean meal, dry mater (DM) basis] or a ground corn with silage (GC) diet (300 g kg−1 of silage and 700 g kg−1 of a concentrate based on corn and soybean meal, DM basis), ad libitum, and four animals of each breed were limited-fed the GC diet [feed restriction (FR), 55% of the DM intake of bulls fed ad libitum, adjusted for the metabolic BW]. Intake was measured daily, and a metabolism trial was conducted with total collection of feces and urine to estimate the ruminally degraded and undegraded protein (intake and nitrogen balance). Blood samples for determination of hormones and metabolites were collected. The data were analyzed using the GLM procedure of SAS adopting a significance level of 0.05. The diet affected only the serum concentrations of triglycerides, HDL, and VLDL, with limited-fed animals presenting smaller concentrations than ad libitum-fed bulls. No difference in blood parameters was observed between animals fed WSC or GC diets. Nellore bulls presented greater T4, cholesterol, HDL, LDL, and serum urea nitrogen concentrations than Angus. Feeding finishing beef cattle with no-roughage diets does not alter their blood parameters. Also, our results support that Zebu cattle might have lower serum removal of nutrients due to a lesser demand for fat and protein deposition than Bos taurus taurus.

title: MOTOR TALENT AND BIOLOGICAL MATURATION IN MILITARY COLLEGE STUDENTS

description: ABSTRACT Introduction The assessment of motor performance in students has been used to identify sports talents. However, there are few studies on this topic, and none in the Sistema Colégio Militar do Brasil (Brazilian Military College System). Objective To evaluate anthropometric, physical motor and maturational indicators, investigate the proportion of motor talents, analyze the relationship between motor talent diagnosis and maturational stage, and compare the profile of student-athletes and non-athlete students of a military college. Methods We assessed 1490 students of both sexes aged 11 to 17 years. A multidimensional battery of tests was applied to assess body size and composition, flexibility, handgrip strength, upper and lower limb explosive strength, velocity, aerobic endurance, and somatic maturation. Data were analyzed using the Chi-square test and analysis of covariance. Results Students showed greater body size, higher motor performance and slightly advanced biological maturation in comparison to data available in the literature. In addition, cut-off points were created for eight sports-related tests to identify students with significantly above-average results, with 11% of motor talents being found. It was also found that motor talents were more frequent in biologically advanced students, and that student-athletes had significant differences in comparison to non-athletes, mainly in terms of motor performance. Conclusion The military school students are larger, stronger, more resistant and more biologically mature when compared to the reference values in the literature, and these characteristics are accentuated in student-athletes. In addition, approximately 1 in 10 of the military college students can be considered a motor talent, and this diagnosis is more frequent in students with early maturation. Level of Evidence II; Diagnostic Study.

title: Reinforced Glass-ceramics: Parametric Inspection of Three-Dimensional Wear and Volumetric Loss after Chewing Simulation

description: Abstract The aim of this study was to investigate the three-dimensional wear, volumetric loss and surface roughness after chewing simulation of two glass ceramics. Lithium disilicate (LD, Emax CAD, Ivoclar) and Zirconia reinforced lithium silicate (ZLS, Vita Suprinity, Vita Zhanfabrick) discs (n=20/g) were scanned to obtain stereolithography (STL) files for each sample. All discs were submitted to chewing simulation with sliding configuration (30 N, 300,000 cycles, 6 mm and 1.7 Hz) with steatite as antagonist. The samples were then scanned again and the volume loss and the deepest defect depth was measured using the superimposed file from the baseline using three-dimensional digital parametric inspection software (GOM Inspect, Braunschweig, Germany). Surface roughness (Ra and Rz) was analyzed with a contact profilometer. Data were analyzed by one-way ANOVA and Tukey test (α=0.5%). ANOVA showed significant differences among the groups. Considering the ceramic volume loss, wear depth defect length and Rz roughness, LD (-22.09±5.57%; 0.80±0.06 µm; 3.08±1.02 µm) showed higher mean values than ZLS (-15.67±4.51%; 0.56±0.09 µm; 1.51±0.90 µm). Ra mean values were similar for both materials (p=0.064). All discs exhibited slight surface scratches along with the sliding direction with pitted wear patterns, while large cracks were observed on wear traces. These same areas can be identified in blue, overlapping the STL files before and after chewing simulation in inspection software. The linear reduction generated by sliding contact shows a graph with a similar wear pattern shape. ZLS was more resistant to wear than LD, with less volume loss and shallower surface defects.
