title: Study of Conservation on Implicit Techniques for Unstructured Finite Volume Navier-Stokes Solvers

description: ABSTRACT: The work is a study of conservation on linearization techniques of time-marching schemes for the unstructured finite volume Reynolds-averaged Navier-Stokes formulation. The solver used in this work calculates the numerical flux applying an upwind discretization based on the flux vector splitting scheme. This numerical treatment results in a very large sparse linear system. The direct solution of this full implicit linear system is very expensive and, in most cases, impractical. There are several numerical approaches which are commonly used by the scientific community to treat sparse linear systems, and the point-implicit integration was selected in the present case. However, numerical approaches to solve implicit linear systems can be non-conservative in time, even for formulations which are conservative by construction, as the finite volume techniques. Moreover, there are physical problems which strongly demand conservative schemes in order to achieve the correct numerical solution. The work presents results of numerical simulations to evaluate the conservation of implicit and explicit time-marching methods and discusses numerical requirements that can help avoiding such non-conservation issues.

title: Evaluation of Galectin-3 and Myocardial Fibrosis in Patients with Hypertrophic Cardiomyopathy

description: Abstract Background: Galectin-3 is the designation given to the protein that binds to ß-galactosides, expressed by activated macrophages and described as a cardiac fibrosis mediator. In hypertrophic cardiomyopathy (HCM), myocardial fibrosis is an independent predictor of adverse outcome; however, the association between Galectin-3 and myocardial fibrosis has not been studied in this cardiopathy. Objective: To evaluate the association of Galectin-3 and the presence of myocardial fibrosis in a patient with hypertrophic cardiomyopathy. Methods: Galectin-3 was measured in automated equipment using the Elisa technique in 100 participants divided into two groups: 50 patients with hypertrophic cardiomyopathy and 50 healthy control subjects. All patients with hypertrophic cardiomyopathy underwent magnetic nuclear resonance with the late enhancement technique to investigate myocardial fibrosis. For the statistical analysis, p values &lt; 0.05 were considered statistically significant. Results: Galectin-3 levels were low and did not show significant differences between patients with hypertrophic cardiomyopathy and the control group, 10.3 ± 3.1 ng/dL and 11.3 ± 2.6 ng/dL (p = 0.12) respectively. Myocardial fibrosis was a common finding and was identified in 84% (42/50) of patients with HCM, but no differences were observed between Galectin-3 levels when comparing patients with and without fibrosis, 10.3 ± 2.4 ng/dL and 10.1 ± 2.1 ng/dL (p = 0.59). Conclusion: The results did not show an association between Galectin-3 and myocardial fibrosis in patients with hypertrophic cardiomyopathy, suggesting that non-inflammatory mechanisms of myocardial fibrosis formation and cardiac remodeling are involved in this cardiopathy.

title: Performance of broilers redneack fed cassava meal

description: This study aimed to evaluate the performance and carcass characteristics of rednecks chickens fed diets containing the cassava root meal in increasing levels of inclusion of 12, 24, 36 and 48%. 360 chicks male, lineage Label Rouge were used, with eight days old, in a completely randomized design with five treatments and six replications of 12 birds each. The birds were fed isocaloric and isonitrogenous from eight to 84 days. Was evaluated feed intake, weight gain and feed conversion. Were killed two birds per cage with 5% ± standard deviation of the mean weight of the cage for evaluation of carcass yield and retail cuts, wings, breast, drumstick, thigh, back, abdominal fat and edible offal (liver, heart and gizzard). Data were subjected to analysis of variance and regression at 5 % probability using the computer program SAS (2001). Concluded that there was a linear increase in weight gain of birds and feed intake with increasing levels of inclusion of the cassava root meal, can be used up to 48% in the diet without prejudice to animal performance.

title: Incidence of ruminite and liver abscess of feedlot bullocks fed high concentrate diets containing feed additives

description: The aim of this study was to evaluate the effects of polyclonal antibodies preparation (PAP) and/or monensin (MON) on the morphology of the rumen papillae, incidence of ruminate (IR) and liver abscess in feedlot bullocks. Seventy-two bullocks Brangus (261.04 ± 34.73kg) were housed in 24 pens (3 bullocks/pen) with6 replications per treatment. The experimental design was completely randomized 2 x 2 factorial, the factors werethe inclusion or not of MON and PAP.After slaughter, the evaluations were performed. For the livers, both the percentage of abscesses and the severity of them were lower (P&lt; 0.01) in animals fed diets with PAP than those fed MON. The inclusion of MON in the diet was only effective in reducing (P&lt; 0.01) the severity of the abscesses in relation to treatment without this additive. There was no effect (P&gt; 0.05) of additives on the IR. The treatment with MON had higher (P = 0.07) surface absorption/cm<sup>2</sup> wall of the rumen and greater (P = 0.10) papillary area compared to treatment without this additive. Number of papillae/cm<sup>2</sup> wall and average area of the papillae showed no difference among treatments. The use of PAP was effective in reducing HA as well as the severity the same, but was not able to improve the shape and structure of the ruminal papillae, as observed with the use of MON.

title: Considerations on health reform process (1993-2013) and social participation in Peru

description: The sanitary reform process undertaken by the Peruvian government (1993-2013) has favored the financial aspect over the health issues and has focused primarily on constraining the costs. This has lead to a restriction in the quality and access to the services. It is important to analyze the Peruvian case especially the health movement led by Foro de la Sociedad Civil en Salud (Forosalud) and what this experience can mean for social movements undertaken in our Latin American continent. In this study the purpose is to analyze the extent of social participation as opposed to contemporary reforms of health systems in Peru.

title: Machado de Assis and Sílvio Romero: slavery, race and scientificism in times of abolitionist campaign (1880s)

description: Abstract The purpose of this article is to explore the historicity and disagreements around the abolitionism and the presence of the “black race” in Brazil in the late nineteenth century, essentially in the 1880s, in the work of Machado de Assis (1839-1911) and Sílvio Romero (1849-1914). In that period, the great public debates revolved around the literary phenomenon, which is the reason why it was decided to investigate the way the slavery and the abolitionism and the scientific racism appear in the texts of the historian and literary critic Sílvio Romero, as well as in the literary production of Machado de Assis. Both of them were prestigious names in the Respublica litterarum and would become founding partners of the Academia Brasileira de Letras in 1897, despite deep intellectual and political differences, which this paper seeks to investigate.

title: YIELD AND FORAGE QUALITY OF SALTBUSH IRRIGATED WITH REJECT BRINE FROM DESALINATION PLANT BY REVERSE OSMOSIS

description: ABSTRACT: Rural communities located in the Brazilian Northeast, especially in the semiarid zone, live with water shortages resulting from erratic rainfall. This work proposes the cultivation of saltbush (Atriplex nummularia) in the Rural Settlement Project of Boa Fé, Mossoró/RN as alternative to the disposal of reject brine from desalination plant on yield of forage. The statistical design was a split-plot design, being four treatments at the plots, related to irrigation with reject brine water, at different levels of soil moisture by moisture from Field Capacity (FC) (100, 85, 70 and 50% of FC) and in subplots and two levels of organic manure (without fertilized and fertilized) with four replications. The variables of yield and forage quality of saltbush were analyzed. It was observed that saltbush has a great production capacity in terms of fresh matter and drought for saltbush under a level of 85% soil moisture in relation to the field capacity of soil, presenting minimal loss of yield; however, this proved to be productive even with the dry soil. The total yield was satisfactory, showing its viability for forage production.

title: Sugar cane bagasse as roughage in sheep diet

description: This study aimed to evaluate the effect of different proportions of concentrate and sugar cane bagasse as roughage exclusive for sheep. The dry matter intake, organic matter, crude protein, non-fibrous carbohydrates and total digestible nutrients in kg/day, increased linearly with increasing proportion of concentrate in the diet. The same behavior was observed for dry matter digestibility. It occurred in a manner contrary to the digestibility of neutral detergent fiber that decreased with the higher levels of concentrate. With the increase of the proportion of concentrate in the diets, quadratic effect was observed to time of rumination, feeding and idleness, and the of concentrations of acetic, propionic and butyric acid in the rumen. Higher proportions of concentrate associated with sugar cane bagasse in naturecan be used in diets.

title: Levels of calcium in the maintenance of internal egg quality of Japanese quails after storage

description: The objective of this study was to evaluate the influence of increasing levels of dietary calcium in improving the external quality and consequent maintenance of internal quality quail eggs at the end of production, stored for 14 days at room temperature. 400 Japanese quails with 46-58 weeks of age, distributed in a completely randomized design where they were tested five calcium levels: 2.95%, 3.25%, 3.55%, 3.85%, 4.15% Ca. The parameters evaluated were: shell thickness, weight and percentage of shell, percentage of yolk, albumen percentage, average egg weight and weight loss of quail eggs. The results showed that increasing levels of calcium promoted after the storage period (P &lt;0.05) better skin thickness, higher percentage of yolk, albumen and a lower percentage of increase in egg weight without significantly influence the weight percentage of bark and weight loss quail eggs after storage at room temperature for 14 days. It was concluded that the increasing levels of calcium in the diet was effective in maintaining the internal egg quality of Japanese quails after room temperature storage for 14 days.

title: Reduced levels of dietary protein on the performance, carcass traits and meat quality of free-range broiler chickens

description: Hence, the objective of this work was to evaluate decreasing levels of crude protein (CP), without altering theratio of essential amino acids, in free-range broiler chickens. Two experiments were conducted, which evaluated broiler chickens during the growing (43 to 56 days, Experiment 1) and finishing (57 to 70 days, Experiment 2) periods. A total of 630 males chickens of the Colonial lineage were housed in 30 boxes (21 chickens/box), with shelter area and paddocks. A completely randomized design composed of five treatments and six repetitions was used. The levels of CP tested were: 17.5, 17.0, 16.5, 16.0 and 15.5%, and 17.0, 16.5, 16.0, 15.5 and 15.0% for growing and finishing periods, respectively. The performance traits, carcass and cutsyield, and meat quality were evaluated. No effect of CP levels on the performance traits was found in broilers evaluated in two periods. Lower hot and cold carcass yield, and higher b* values in chickens were observed at the levels of CP of 16.26, 16.25 and 15.81%, respectively. However, the higher b* values may be a result of the higher corn gluten concentration in the diet. When the ideal ratio between amino acids and lysine is met, it is possible to reduce the levels of dietary CPin free-range broiler chickens down to 15.5 and 15.0% in the growing and finishing periods, respectively, without leading to a decreased performance, and carcass and cutsyield.

title: Production of growing male pigs: a meta-analysis

description: A meta-analysis was carried out in order to study performance, carcass characteristics and nutritional interactions in castrated, entire and immunocastrated males. A total of 27 studies were used in the database, totaling 2917 animals. The meta-analysis followed three sequential analyses: graphical, correlation and variance–covariance. Entire males showed feed intake 9% lower (P&lt;0.05) than surgically castrated males and 11% lower (P&lt;0.05) than immunocastrated pigs. Weight gain was higher (P&lt;0.05) in immunocastrated pigs in comparison to entire (9%) and castrated (12%) males. Daily weight gain showed positive correlation (P&lt;0.05) with crude protein intake in all sex categories. The intercepts in the equations estimating the total lysine intake depending on the weight gain were 15.3; 20.4 and 22.3g for surgically castrated, immunocastrated and entire males, respectively, indicating empirically that the entire males have higher lysine requirement for maintenance in comparison to surgically castrated pigs. Hot carcass weight and carcass yield did not differ (P&gt;0.05) between treatments. However, castrated males showed lower lean meat content (P&lt;0.05) in comparison to immunocastrated (5%) and entire (7%) males. The backfat thickness of surgically castrated pigs was 21% higher (P&lt;0.05) relative to immunocastrated and 27% higher (P&lt;0.05) in comparison to entire pigs. Performance responses differ in surgically castrated, entire and immunocastrated male pigs. The meta-analysis indicated that the nutritional variables and maintenance requirements in different sexual categories of pigs should be considered in future research studies.

title: Preventive use of toltrazuril to control coccidiosis in meat goats raised in semiarid region

description: This study aims to evaluate the effectiveness of toltrazuril in controlling coccidiosis in meat goats raised extensively in semiarid region and determine the most appropriate age for performing treatment. Forty kids were divided by age and treated with single dose of toltrazuril at 14, 21, 28 and 35 days aged. Fecal samples were collected weekly to determine the number of oocysts per gram of feces (Oopg) after treatment. The kids were weighed weekly to determine average daily gain (ADG). All treated kids showed no oocysts in the feces by at least one week after treatment. The Oopg of treated kids regardless of age at treatment was lower than the untreated (P&lt;0.05) along 10-11 weeks post-treatment. The ADG was similar for all treatments evaluated. The Oopg was not influenced by sex but it was by age at treatment. Kids treated at 21 days aged showed no oocysts in the feces for a longer period than the other. Preventive treatment with toltrazuril performed at 21 days aged was suitable for control of coccidiosis in kids raised extensively in semiarid region.
