title: Effects of Aging Temperature, Time, and Pre-Strain on Mechanical Properties of AA7075

description: Aluminum alloys of the 7xxx series (AA7075) are preferred in the aerospace and automotive industries due to their low densities, high strength, good corrosion resistance properties. Additionally, these alloys show the most effective aging properties among aluminum alloys. For this reason, it is very important to determine the most appropriate aging parameters for microstructural development. Literature review reveals that the effect of pre-strain on springback has not been studied yet. In this study, the effects of aging temperature, time, and pre-strain on mechanical properties are investigated for AA7075. Precipitates present in solid solutions of AA7075 and their effects are examined. Results reveal that MgZn2 precipitation is not observed at aging temperatures of 120 and 160 ºC. After the formation of MgZn2 precipitates, microstructure becomes softer when aging continues at a higher temperature or longer period of time. It is clearly seen that pre-strain causes Portevin-Le Chatelier (PLC) effect after aging at 120 and 160 ºC for aging times of 30 and 90 minutes.

title: Genetic parameters, genetic trends, and principal component analysis for productive and reproductive traits of Guzera beef cattle

description: ABSTRACT The objectives of this study were to estimate genetic parameters and genetic trends and perform principal component analysis for the following traits: body weight adjusted at 210 days of age (W210), one year (W365), and yearling or 450 days of age (W450); weight gain from birth to weaning or 210 days of age (WGBW), from weaning to 365 days of age (WGW365), and from one year to yearling (WGY); and scrotal circumference adjusted at 365 (SC365) and 450 (SC450) days of age of Guzera beef cattle. Variance components were estimated under a two-trait animal model using the restricted maximum likelihood method. The fixed effects included in the model were birth season, contemporary group, and covariable age of dam at calving as linear and quadratic effects. Heritability estimates ranged from 0.10 (WGY) to 0.41 (W450 and SC450). The studied traits could be used as selection criteria because of their sufficient additive genetic variability to respond to the selection process. However, lower selection efficiency is expected for WGBW and WGY. Genetic trends studied were significant for all traits, except WGY. The W365 and W450 traits belonged to the “Genetic Merit Total” index and responded to selection with favorable genetic gain per year. The traits that were not included in the selection index showed favorable positive genetic correlations attributed to the indirect selection processes. The principal component analysis identified two groups of traits. The first group related to body weight and weight gain and the second related to the scrotal circumference, indicating that selection could be applied to one group of traits within each observed group. The genetic gains were attributed in the same direction for the other traits belonging to the groups. Thus, we recommend selecting animals for W365 based on first group, and SC365 based on second.

title: Inbreeding depression in Holstein cattle in Brazil

description: ABSTRACT The objective of this study was to evaluate inbreeding depression in Holstein cows in Brazil, considering their 305-day milk production (MP), age of first calving (AFC), and calving interval (CI). The effects of inbreeding depression on the traits were determined using four regression models (linear, quadratic, exponential, and Michaelis-Menten) about the errors generated by the animal model. The linear model was significant for CI, and the quadratic model was significant for CI and AFC. The Michaelis-Menten and exponential models were significant for MP, AFC, and CI. Inbreeding depression affected MP and CI. Cows with inbreeding coefficient of 15% produced approximately 260 kg less milk than non-inbred cows. A 1% increase in the inbreeding level resulted in an unfavorable increase of CI of 1.88 days. The quadratic and exponential models showed no variations for CI with increasing inbreeding level; however, the Michaelis-Menten model showed a positive effect of inbreeding on CI. Despite of the small number of inbred Holstein cows, the inbreeding negatively affected milk production and calving intervals. Therefore, breeders should monitor their cattle inbreeding levels. The Michaelis-Menten and exponential non-linear models are best suited to fit inbreeding data of Holstein cows.

title: The resumption of the implementation process of the National Permanent Health Education Policy in Brazil

description: ABSTRACT This work aimed to describe and to analyze the most recent initiatives carried out, within the scope of federal management, for the implementation of the National Permanent Health Education Policy (PNEPS). It takes as reference the Kingdon public policy cycle, describing how the topic was included in the government agenda in 2003, and analyzes the content of the documents that materialize the proposals of the Policy. Subsequently, it focuses on the description and analysis of the movement triggered in 2017-2018, with the accomplishment of a series of regional events, which resulted in the identification of the weaknesses faced in the implementation process of the PNEPS, subsidizing a set of proposals that referenced the initiatives triggered, aiming at the effective implementation of the PNEPS in the scope of the Unified Health System (SUS).

title: Strategic human resource management in the Brazilian Federal Legislative: conditions for the implementation

description: Abstract This research aimed to identify interfering aspects in the implementation of strategic human resource management in Brazilian Federal Legislative bodies, as well as the possible relations between them. Through interviews and focus groups with 16 managers of the Federal Senate and the Chamber of Deputies, 21 interfering aspects were identified, divided into institutional, political, organizational, and sectoral categories. The study elaborated theoretical-empirical models of the influences exerted by each of the aspects on the others, which supported the conclusion that the most significant constraints are of political nature, since they would define the resources and the autonomy available to human resource management units to lead the implementation process.

title: Party filiation and appointment for positions in the Brazilian federal bureaucracy (1999-2018)

description: Abstract How many are the top and middle-level Brazilian federal bureaucracy appointees, and to which party are they affiliated? Are there differences among presidential mandates regarding the number of these professionals and their party affiliation? This study seeks to answer these questions, by building a new database that gathers the number of party-affiliated public officials that were appointed to Cargos de Direção e Assessoramento Superior (DAS) (position of director and high level consultant). Descriptive analysis found that the proportion of party-affiliated among appointees increased during the Workers’ Party (PT) governments and higher among appointed professionals that were not civil servant. The power-sharing among parties - mainly between the party of the president and the others - varies significantly according to the government. The partisan control over appointees is milder in middle-level and stronger at top-level positions. However, a minority of appointees are party members, even among the top-level bureaucracy. Therefore, we suggest that the political networks go beyond the party affiliations. To understand these networks it is necessary to reassess the role of party politics in shaping the executive agenda and enable reinterpretation of how presidents build and manage the government coalition and the support to their agenda in the legislative arena.

title: Blood parameters and hepatic histopathology of broilers fed rations supplemented with essential oils

description: ABSTRACT This study aimed to evaluate the hematological profile, hepatic function, and histopathology of mixed-sex broilers fed rations supplemented with microencapsulated essential oils from Cymbopogon flexuosus (lemon grass) and Lippia rotundifolia (chá-de-pedestre). One hundred and fifty Cobb chicks were housed in cages from 1 to 42 days of age in a completely randomized design, with six replicates with five chickens in each of five treatments (150 total chicks): basal diet without antibiotic growth promoter (negative control), diet with enramicina and salinomycin (positive control), diet with lemon grass essential oil, diet with L. rotundifolia essential oil, and diet with a mixture of lemon grass and L. rotundifolia essential oils. Mean corpuscular volume (MCV) and mean corpuscular hemoglobin (MCH) were significantly lower in untreated broilers (negative control group). Gender was not associated with erythrogram values, but aspartate aminotransferase activity (AST) was higher in females. Gamma-glutamyl transferase (GGT) was higher in chicks in the group that received rations with lemon grass oil. Broilers that received L. rotundifolia oil developed more hepatic lesions, although no effect of sex was observed related to the lesion score. Biliary hyperplasia and fibroplasias were observed in all groups, with higher histopathology scores in broilers that received diets containing L. rotundifolia oil. Mixed-sex broilers fed rations supplemented with lemon grass and L. rotundifolia essential oils have normal complete blood counts and unspecific hepatic lesions and are characterized by lipidosis, hyperplasia of the bile ducts, and fibroplasia.

title: Femoral Hernia Containing the Right Fallopian Tube: A Rare Finding

description: Abstract Femoral hernias comprise a small proportion of all groin hernias. They are more common in women and have a high rate of incarceration and strangulation, leading to emergency repair. A 61-year-old female patient was admitted to the emergency department complaining of a 2-day painful lump in the right groin, that had become more intense in the last 24 hours. Physical examination suggested the presence of a strangulated femoral hernia, and the patient underwent emergency surgical repair. Intraoperatively, the right fallopian tube was observed in the hernia sac. Since there were no signs of ischemia, the tube was reduced back into the pelvic cavity and the hernia was repaired. The postoperative period was uneventful, and the patient was discharged without complications, 3 days after surgery.

title: Elemental Concentration and Sulfur Chemical Speciation in the Amazonian Plant Andira surinamensis Using Synchrotron Radiation Techniques (SR-XRF, XANES), RBS and WD-XRF

description: The inorganic composition of the bark and leaf of a plant from the Amazon rainforest, Andira surinamensis, was determined using two non-destructive, multi-element techniques: X-ray fluorescence (XRF) and Rutherford backscattering spectrometry (RBS). XRF measurements were made using both a conventional X-ray source and synchrotron radiation. It was observed that although magnesium, aluminum, silicon, phosphorus, sulfur, chlorine, and potassium are present in higher concentrations in the leaf, calcium is about three times more concentrated in the bark. Manganese, iron, copper, zinc, strontium and barium were also detected, with barium showing a concentration above the minimum toxicity level for plants. Chemical speciation of sulfur, performed using the X-ray absorption near edge structure (XANES) technique, showed that sulfur is present in several oxidation states, with a much larger contribution from the inorganic sulfate in the leaves. The article evidences that the combined use of synchrotron radiation and non-destructive multi-element techniques allows for an efficient and accurate determination of the inorganic composition and chemical speciation in plants.
