title: Genetic identification, clinical and epidemiological aspects of an equine infectious anemia outbreak in the Rio Grande do Sul State, Brazil

description: ABSTRACT: The study describes the genetic identification, clinical, and epidemiological characteristics of an outbreak of equine infectious anemia occurring in the state of Rio Grande do Sul, Brazil. Three animals kept in the periurban region of Uruguaiana city tested positive for the AGID test. The serology was performed as a requirement for transit. None of the animals showed clinical signs of infection, one animal was necropsied, and the others were stolen. In the post-mortem examination, no macroscopic changes were observed, and microscopically, discrete hemosiderosis was detected in fragments of the liver and spleen. Amplifying and sequencing a proviral DNA fragment in blood, spleen, and mesenteric lymph node samples confirmed EIAV infection. Phylogenetic analysis of the first sequenced EIAV sample from the Rio Grande do Sul State indicates a high similarity with other Brazilian samples. Results confirmed the viral presence in the state’s herds and described epidemiological and virological characteristics of EIA that contribute to the maintenance and dissemination of the virus in herds.

title: Digiwork: Reflections on the scenario of work mediated by digital platforms in Brazil

description: ABSTRACT Purpose: This article analyzes the Brazilian scenario of work mediated by digital platforms (digiwork). Originality/value: Digiwork represents an alternative work arrangement to the traditional long-term employment model, with the highest growth rate in recent years. Details of this scenario are still unclear regarding the quantity and diversity of the offered products and services and the number of individuals involved. This article presents information and reflections that contribute to understanding these data in Brazil. Design/methodology/approach: This is an analytical-exploratory study. Scientific articles were used to discuss technological, political, and socioeconomic influences that supported the emergence of digiwork and its effects on the labor market and the workforce. In order to support this discussion, a documental analysis of websites and mobile application software was carried out, allowing for a qualitative-quantitative mapping of Brazil’s current digital intermediation platforms. Findings: More than 100 companies operating in the country were identified as offering 11 types of services in this business, indicating a growing trend. A diversification movement was also observed, absorbing professionals with different kinds of training and schooling levels. Such growth is in line with the political-economic trend of encouraging the loosening of labor relations, which individualizes and informalizes the bonds, emphasizing the need for debate on the regulation of this work arrangement and more research to investigate its repercussions on the worker’s health, also considering the heterogeneity present in this new class.

title: Risk factors associated with stillbirth in sows

description: ABSTRACT: In this study, the risk factors associated with stillbirth in sows were identified and their odds ratio assessed. For this purpose, 587 farrowings on Farm A and 929 on Farm B were monitored, and the sow parity, body condition score, farrowing duration, total number of piglets born, numbers of live births, stillbirths, and mummified piglets, obstetric interventions, and piglet sex and weight were recorded. At the end of farrowing, piglets classified as stillborn were necropsied to confirm the diagnosis. Consequently, 5.49% of the piglets on Farm A and 5.10% of those on Farm B were stillborn. On both farms, sows with a high parity, prolonged farrowing, and a large litter size had the highest odds ratio of stillbirths. On Farm B, farrowing intervention through the use of vaginal palpation and oxytocin increased the odds of stillbirth by 1.7 and 2.5 times, respectively. Heavy litters increased the odds of stillbirth by 1.4 times. Additionally, low-birth-weight piglets were 2.3 and 3.1 times more likely than their medium-birth-weight and high-birth-weight counterparts, respectively, to be stillborn. In conclusion, on both farms, the risk factors associated with stillbirth were a high parity, a large litter size, and prolonged farrowing.

title: Minituber production in yam for alternative vegetative propagation: types of cuttings, substrates, and anatomy

description: ABSTRACT: Yam is a tuber vegetable crop with vegetative propagation. The crop is low yielding due to the difficulty of obtaining quality material for propagation and the high cost of acquisition. The cutting technique is a new alternative for vegetative propagation of yam. The present studyevaluated the production of minitubers of yam through cuttings, and follow the formational growth of the minitubers. Different types of cuttings, obtained from three positions on the shoots, and three substrates were tested. The types of cuttings and substrates did not significantly affect the number of minitubers per cutting, this number ranging from 1.18 to 1.75. The best results were obtained using Tropstrato Florestal® and median-position cuttings for the following variables: minituber length (17.47 mm), minituber diameter (12.63 mm), minituber fresh weight (2.12 g), and percentage of cuttings with two minitubers (75%). Anatomical analysis showed cell divisions and starch accumulation in the nodal region at seven days after planting the cutting. Emergence of the minituber could be observed at 21 days. The production of yam minitubers through stem cuttings is enhanced using cuttings obtained from the median position of the shoot and using the commercial substrate Tropstrato Florestal®.

title: Influence of the incorporation of flexographic photopolymer plate residues on the mechanical properties of epoxy

description: Abstract A thermosetting epoxy polymer composed of diglycidyl ether of bisphenol A and triethylenetetramine (DGEBA/TETA) was modified by incorporating flexographic photopolymer plate residues (rubber microparticles). The photopolymer plate residues were processed in two ways: (a) by grinding and performing particle size classification (where the resulting samples were denoted PP) and (b) by polyester layer separation and grinding the elastomeric fraction by cryogenic grinding (where the resulting samples were denoted ER). Both residual particles were incorporated into the epoxy at concentrations of 2.5, 5 and 7.5 wt%. The main results indicate that PP was not efficient as a modifier of the epoxy system. A reduction in mechanical properties (maximum tensile strength and deformation) was observed in the samples produced with PP in different concentrations. But, when the ER is incorporated, an increase in tensile property and in the deformation capacity, as well as impact resistance was observed in samples produced with ER. Scanning electron microscopy analysis showed a greater presence of voids in formulations produced with PP, which corroborates the decrease in the tensile strength of these samples.

title: Access to childbirth care services in the interior of Pernambuco, Northeast region of Brazil

description: ABSTRACT OBJECTIVE To analyze the access of women to the public health system network to childbirth care, highlighting the barriers related to the “availability and accommodation” dimension in a health macroregion of Pernambuco. METHODS Ecological study, conducted based on hospital birth records from the Hospital Information System of the Brazilian Unified Health System (SUS), and information from the state’s Hospital Beds Regulation Center, about women residing in health macroregion II, in 2018. Displacements were reviewed considering the geographic distance between the municipality of residence and that of the childbirth; estimated time of displacement of pregnant women; ratio of shifts blocked for admission of pregnant women for delivery; and the reason for unavailability. RESULTS In 2018, health macroregion II performed 84% of usual risk childbirths, and 46.9% of high-risk childbirths. The remaining high-risk childbirths (51.1%) occurred in macroregion I, especially in Recife. The reference maternity for high-risk childbirths in that macroregion had 30.4% of the days of day shifts and 38.9% of the night shifts blocked for admission of childbirths; the main reason was the difficulty in maintaining the full team in service. CONCLUSIONS Women residing in the health macroregion II of Pernambuco face great barriers of access in search of hospital care for childbirth, traveling great distances even when pregnant women of usual risk, leading to pilgrimage in search of this care. There is difficulty regarding availability and accommodation in high-risk services and obstetric emergencies, with shortage of physical and human resources. The obstetric care network in macroregion II of Pernambuco is not structured to ensure equitable access to care for pregnant women at the time of childbirth. This highlights the need for restructuring this healthcare services pursuant to what is recommended by the Cegonha Network.

title: On the precision and Accuracy of the acoustic birefringence technique for stress evaluation

description: This paper presents a numerical procedure for estimation of the precision and accuracy of the acoustic birefringence technique for evaluation of residual and applied stresses in civil structures and components. This procedure accounts in an automatic and systematic way for the uncertainties in the input data and their propagation throughout the calculations. The acoustic birefringence is defined from the speeds of two mutually orthogonal volumetric waves of normal incidence, but when the use of a pulse-echo measurement system is feasible, the birefringence can be defined directly from the time-of-flight of the waves, since they travel the same physical space. The times-of-flight of the waves are estimated by coupling the mathematical techniques of cross correlation and data interpolation, whereas the material’s acoustoelastic constant is determined via a weighted linear regression. As an example, the estimation of the precision and accuracy in the evaluation of the stresses in a beam under bending is discussed.

title: Preliminary validity for the Big Five Inventory-2 in Brazilian adults

description: Abstract The Big Five Inventory-2 (BFI-2) assesses personality through the big five factor model model (FFM). This study aimed to verify whether the internal structure of the BFI-2 is corroborated in a Brazilian sample. Participants were 908 cisgender adults, aged between 17 and 93 years, 532 of whom were women. Confirmatory factor analysis and Exploratory structural equation modeling were performed with the BFI-2. The 15 facets of personality resulted in adequate fit and reliability, mainly for the respondents under 60 years of age. We conclude that the BFI-2 presents evidence of preliminary validity based on its internal structure, although further validity studies are required with the instrument, to testify its psychometric quality.
