title: Identification of 20 species from the Peruvian Amazon tropical forest by the wood macroscopic features

description: ABSTRACT Background: The biodiversity of the Peruvian Amazon tropical forests is one of the most expressive in the world, with 2500 forest species, although restricted to about 250 tree species used commercially. This species diversity indicates the challenge magnitude for research in taxonomy and timber species identification. Likewise, it implies the complexity of biodiversity conservation and restoration measures, which are directly related to the control of deforestation, cutting and transport of illegal wood. With this objective, the present study describes the macroscopic wood anatomical features in order to identify 20 tree species from Peruvian Amazon Forest, “Selva Central”, including an identification key and tree species botanical validation. Results: The wood species are included in 12 families commonly found in the tropical forests of Peru, highlighting the Fabaceae (25%), Moraceae (15%), Podocarpaceae and Lauraceae (10%) families and are sold as timber for several uses and applications in the internal market and for export. The wood species presented common anatomical features, such as diffuse porosity, visible axial parenchyma mainly distinct, and, eventually, with ray storied, e. g: A. cearensis, M. balsamum and M. peruiferum. Conclusion: The tropical tree species identification is possible by analyzing their wood macroscopic anatomical structure. The results can be also applied in the wood trade traceability by controlling deforestation and illegal wood commerce and in proposing policies for biodiversity conservation and sustainable use of natural resources. They constitute, likewise, a database for the recent wood identification methodologies presented in the specialized literature.

title: Effect of heat stress and solar radiation on dry matter intake, biochemical indicators, production, and quality of Holstein and Jersey cows' milk

description: ABSTRACT The objective of this work was to compare the dry matter intake, milk yield and quality, physiological and biochemical parameters in Holstein (n=10) and Jersey (n=10) cows under heat stress and insolation, in two treatments: CL - cooling by ventilation and sprinkling and HS - heat stress and insolation. Data were submitted to ANOVA. There was an interaction between treatment and breed and day effect for dry matter intake. For consumption in % of body weight, CL and Jersey cows consumed more. CL cows produced more milk and 3.5% fat-corrected milk. Feed efficiency was similar between treatments and breeds. Fat, lactose, total solids, and somatic cell score did not differ. The concentration of milk urea nitrogen was higher for CL cows. Milk from Holstein cows had greater stability to alcohol, and from HT cows had a greater freezing point of milk. HT cows had higher respiratory rates in the morning and surface temperatures in the afternoon. There were no differences in beta-hydroxybutyrate and glucose concentrations. Heat stress, with insulation, reduces intake, especially in Holstein cows, as well as milk production and increases the freezing point of milk, respiratory rate, and surface temperature.

title: A tool for managerial decision making in emerging economies, and asymmetric cost behavior: Evidence from Ecuador

description: Abstract Business sectors may be affected by changes in their activity levels. For this reason, the administration requires tools that allow to show the impact on its profitability. The asymmetry in the behavior of the costs of companies belonging to the economic sectors of beverage production and meat processing in Ecuador for the period between 2012 and 2018 was analyzed. 291 companies that presented activity were studied. For the study of sticky costs, 3 analysis variables were defined: operational income, total costs and expenses, and personnel costs and expenses; to which, four different study techniques were applied. The different analysis techniques show consistent and robust results, with the exception of the estimation using panel data in the meat sector. The study´s results show an asymmetric behavior within the costs, which suggest an inability for Ecuadorian companies to lower their costs due to a drop on their income, whereas, when their income raises, so does their cost; a fact that matches the recent evidence found worldwide. This asymmetry could be explained by factors such as regulatory rigidity or expectations of a quick business recovery.

title: Reflections on the use of the Progress Test in the programmatic student assessment

description: Abstract: Introduction: The Progress Test (PT) is a well-established and mostly successful modality of student knowledge assessment in the health professions, mainly those in the medical area, with the potential to contribute substantially to the formative and informative purposes (quality control and indication of improvement in the teaching-learning processes). Additionally, the PT has characteristics that are adequate for its inclusion in institutional evaluation systems that facilitate the formative purpose, such as programmatic assessment (PA), but that also meet the summative purpose. In schools that have defined actions aimed at introducing PA in their undergraduate courses, it is necessary to reflect on the strengths and limitations of using PT in the evaluation system. Development: based on the considerations of a working group representative of the entire institution, tasked with proposing means of introducing PA in a new curriculum for the medical course, with international advice with experience in both PT and PA, we generated a reflection on this topic, based on the authors’ experience and data from the literature. It is proposed that, within the longitudinal perspective of the PA, the PT constitutes one of the pillars in the assessment of knowledge. The PT can be used as a basis for monitoring the students, in the context of their class (cohort), and its results should be discussed with the mentors who accompanies and supports them. The PT must also play a central role in management, as a source of information for eventual review and qualification of the curriculum and its teaching-learning activities. It is predictable that the use of the PT in PA will bring different challenges and barriers, which will be more easily overcome if the institution has already consolidated experiences in the application of institutional exams and in faculty development for the production of good quality objective questions. Conclusion: the effectiveness of the PT within the institutional PA system will depend on measures aimed at increasing its effectiveness in the assessment and that encourage the student’s active participation, reflecting on their performance in the PT, with the support of their mentor, aiming to engage in actions that encourage learning self-regulation.

title: Cardiac Rehabilitation in a Transplanted Person with Emery-Dreifuss Muscular Dystrophy

description: Abstract Emery-Dreifuss muscular dystrophy is a rare hereditary neuromuscular disease. Its manifestations begin primarily in childhood. The most frequent manifestations are progressive muscle weakness, atrophy that usually begins in the scapula-vertebral region, extending later to the pelvic girdle, and spinal stiffness. Patients can also manifest cardiac involvement as palpitations, syncope, exercise intolerance, congestive heart failure, and variable heart rhythm disturbances.1 - 3 The presence and severity of these manifestations can vary according to the individual and the disease’s subtypes. 2 Cardiac involvement is the most worrisome feature of this disease, and there are some reports of the need for heart transplantation in this dystrophy. 4

title: Efficient Crack Length Measurement Using A* Shortest Path Methodology for a Phase-Field Fracture Framework

description: Abstract Accurately measuring a crack length is a crucial aspect of experimental fracture tests. In this work, we present an innovative application of the A* (A-star) shortest path methodology to track different shapes of cracks from numerical simulations. This approach is highly efficient, significantly improving the speed and accuracy of crack length measurements. Furthermore, we introduce a modified weight cost function that follows the crack path in the damage field, enhancing the accuracy of our method. The effectiveness of the proposed procedure is shown by fabricating damage fields with different geometry and good agreement when compared to the exact values. In addition, we evaluate a time-dependent crack propagation case, achieving high accuracy. We present all features and steps of the procedure to showcase its efficacy in accurately measuring the length of a crack path. Finally, we validate our method using a phase-field fracture framework and compare it with the compliance technique. The results show that the proposed method is applicable in finite element analyses with recovering accurate results.

title: Intention of breastfeeding and association with sociodemographic, obstetric characteristics and experience with breastfeeding among pregnant women

description: Abstract Objectives: to estimate the intention of breastfeeding (IBF) duration and its association with sociodemographic, obstetric characteristics and experience with breastfeeding among pregnant women undergoing prenatal care. Methods: cross-sectional study, with pregnant women undergoing prenatal care in public health services in Colombo, Paraná, Brazil. The duration of IBF was questioned to pregnant women. Negative binomial Poisson regression with robust variance adjustment allowed estimating crude and adjusted prevalence ratios (PR), and 95% confidence intervals (CI95%) of the association between IBF duration and exposure variables. Results: among the participating pregnant women (n = 604), 7.9% reported having IBF for less than six months, 28.0% from six to 11 months, 38.3% from 12 to 23 and 25.9% for 24 months or more. The mean IBF time was 13.5 ± 8.4 and median of 12 months. Pregnant women with moderate food insecurity (PR=1.34; CI95%=1.04-1.73), multiparous women (PR=1.13; CI95%=1.00-1.26), and who reported having been breastfed as babies (PR=1.19; CI95%=1.02-1.40) had a longer IBF time. Conclusions: food security situation, primiparity and exposure to breastfeeding in childhood are determinants of IBF during pregnancy.

title: A bullous variant of central serous chorioretinopathy treated with oral spironolactone

description: ABSTRACT We report the case of a 39-year-old male patient who presented with visual loss in the right eye for 6 weeks. The best-corrected visual acuity was counting fingers in the right eye and 20/30 in the left eye. The fundus examination demonstrated a right retinal detachment inferiorly extending to the fovea and a left macular serous detachment. After multimodal imaging study, the patient was diagnosed as having a bullous variant of central serous chorioretinopathy and treated with oral spironolactone associated with adjuvant laser photocoagulation. The retinal changes resolved after 6 months. The final visual acuity was 20/20 in both eyes.

title: Early ontogeny of tetra Markiana nigripinnis (Characiformes: Characidae)

description: Abstract The early development of Markiana nigripinnis is described by morphological characters, pigmentation, and morphometry. Larvae were obtained through semi-natural breeding, collected, fixed, and identified according to their development. Eighty individuals with standard lengths ranging from 3.1 to 24.3 mm were analyzed. Larvae are poorly developed at hatching, with a relatively large yolk sac and finfold. At the preflexion stage, the eyes are pigmented, the mouth and anus are functional, the yolk is completely absorbed, and the pectoral fin bud emerges. At flexion, the first rays of the caudal, anal, and dorsal fins become evident. The pelvic fin bud emerges only at the postflexion stage, in addition to the complete absorption of the finfold. Pigmentation is distributed throughout the body, with a greater concentration on the top of the head, around the mouth, and at the base of the caudal fin. The myomere total number ranged from 34 to 49 (16–23 preanal, and 18–27 postanal). Juveniles show morphological characteristics like adults. The fins ray number are pectoral: 11–13, pelvic: 5–7, dorsal: 8–11, caudal: 16–27, and anal 30–47. The morphometric relationships reveal variations in growth along the early ontogeny of the species.
