title: Female entrepreneurship and challenges faced by women entrepreneurs to reconcile conflicts between work and family: multiple case study in travel agencies

description: Abstract Women have gained more and more space in various professional areas and this development also occurs in the field of entrepreneurship. In Brazil GEM 2013 identified for the first time, that the number of new woman entrepreneurs was higher than male entrepreneurs. However, it is recognized that women entrepreneurs face many difficulties when trying to reconcile their companies with the family. The main objective of this research is to analyse the challenges faced by women entrepreneurs of travel agencies to reconcile the conflict between work and family. This study adopted the multiple cases research strategy and were selected seven women creators and managers of travel agencies in the cities of Aracaju and the Barra dos Coqueiros, in the state of Sergipe (east coast of Brazil). In an attempt to reconcile well the multiple roles these women often face the frustration and guilt. At this moment, it shows the importance of emotional contribution of husband and children. It is noticed that the search for balance between the conflicting demands generate emotional distress and / or physical.

title: Impact of Wood Moisture in Charcoal Production and Quality

description: Abstract The charcoal production when performed in woods with high moisture content negatively impacts the pyrolysis and causes an increase of greenhouse emissions. The aim of this study was to investigate the effects of moisture on the production and quality of charcoal for the pig iron industry. The slow pyrolysis of Eucalyptus sp. was carried out in four different wood moistures, 0, 20, 40 and 60% (dry base). The charcoal and gas yield decreased according to the increase of wood moisture. On the other hand, the bio-oil yield and charcoal friability increased along with the moisture content. The proximate analysis, bulk density and higher heating value of the charcoal were not influenced by the moisture content. The use of wood with moisture content below 20% in the production of charcoal is an alternative to improve productivity, contributing for the economic sustanainability of this sector.

title: Organic Residues and Bokashi Influence in the Growth of Alibertia edulis

description: Abstract The aim of this study was to evaluate the use of different organic residues and bokashi in the substrate formulation in the initial growth of marmelo-do-cerrado. The experiment was carried out in pots under shading (50%). The following organic residues were tested: poultry manure (PM) with rice husk base, PM with wood shavings base, Organosuper®, and castor bean meal, in a control with only soil. All treatments were assessed with and without bokashi. The experimental arrangement was a 5 × 2 factorial scheme in a randomized block design with four replicates and four plants. The greatest plant height was observed when the plants were cultivated in PM with rice husk base with bokashi. The pigment contents, photochemical efficiency, biomasses and quality of seedlings were highest in Organosuper® with bokashi. We recommend the use of Organosuper® and PM with rice husk base, both with bokashi, in the growth of marmelo-do-cerrado.

title: Phenology of Copernicia alba in Flooded and Not Flooded Environments

description: Abstract The objective of this study is to describe the reproductive and vegetative phenological patterns of individuals of Copernicia alba, popularly known as “carandá,” in two areas of the Pantanal of Mato Grosso and to test the relations between their phenophases and climatic seasonality. We obtained the phenological aspects of the carandá through a biweekly observation of 22 individuals from two areas of the Pantanal of Mato Grosso between August 2015 and August 2017. The carandá population presented a perennial behavior, flowering during the dry season and greater leaf intensity in the transition period to the rainy season. Budding, although continuous, was intense in the rainy season, and the leaf deciduous pattern had a direct interference from the absence of rainfalls in the dry period. The incidence of floral buds occurred in the dry period, and the flowering occurred between the dry and rainy periods. The fruiting period occurred in the rainy season, indicating a high synchronism of phenophases.

title: Crack consumption from the perspective of gender and vulnerability: a review on the phenomenon

description: The complexity of crack consumption has generated great challenges for managers. The objective of this study was to analyze, based on a ten-year literature review, gender issues and vulnerability conditions associated with this consumption. By searching on LILACS, PUBMED and PSYCINFO databases, 114 articles were located, of which 20 were selected. The results of those studies show that, instead of vulnerability, risk factors arise as cause for the development of abuse or dependence on psychoactive substances, as well as protective factors, which are evaluated here as for the construction of public policies for that population.

title: EVALUATION OF FEEDING RATES IN THE PRODUCTION OF LITOPENAEUS VANNAMEI SHRIMP USING ARTIFICIAL SUBSTRATES

description: Abstract The objective of this study was to evaluate the the influence of feeding rate and different artificial substrates on both the water quality and growth performance of Litopenaeus vannamei shrimp. The experimental design was randomized blocks with five treatments and four replicates, with a density of 30 shrimp m-2 and mean weight of 2.8 g. The experiment lasted 49 days, and during this period, artificial substrates did not influence the water quality. The increase in the feeding rate influenced the dissolved oxygen of treatments. The final average weight, average final length, final biomass, productivity, and feed conversion rate showed significant differences (p &gt; 0.05). The best food conversion factor was provided by the treatment with a feeding rate of 2%. The treatment with a feeding rate of 4% of biomass showed the best growth performance, except for the feed conversion rate. Results showed that for the percentage of 25% of the area of artificial substrates, there is an optimum feeding rate of between 5.13% and 5.54% of shrimp biomass, resulting in maximum production.

title: Germination and Initial Seedling Growth of Schizolobium amazonicum on Different Substrates and Irrigation Depths

description: Abstract Due to the good silvicultural characteristics of Schizolobium amazonicum (parica) and its versatility (planting and use), the species has become an alternative in commercial exploitation. Aiming to verify the influence of irrigation depth and substrate on the germination and growth of Parica seedlings, a greenhouse experiment was conducted using randomized blocks in a 2 × 4 bifactorial scheme, with two types of substrates (washed sand and commercial substrate) and four irrigation depths corresponding to 50%, 100%, 150% and 200% of the reference evapotranspiration (ETo), with five replications. Germination rate, emergency speed index and biometric variables were evaluated. The commercial substrate combined with the irrigation level of 50% of ETo favored a higher emergence speed and germination rate. In the growing phase, the irrigation level of 150% of ETo combined with the commercial substrate produced better results, indicating greater survival and development in the field.

title: Clinical and subclinical maternal hypothyroidism and their effects on neurodevelopment, behavior and cognition

description: ABSTRACT Clinical and subclinical hypothyroidism are the most common hormonal dysfunctions during pregnancy. Insufficient maternal thyroid hormones (THs) in the early stages of pregnancy can lead to severe impairments in the development of the central nervous system because THs are critical to central nervous system development. In the fetus and after birth, THs participate in neurogenic processes, cell differentiation, neuronal activation, axonal growth, dendritic arborization, synaptogenesis and myelination. Although treatment is simple and effective, approximately 30% of pregnant women in Brazil with access to prenatal care have their first consultation after the first trimester of pregnancy, and any delay in diagnosis and resulting treatment delay may lead to cognitive impairment in children. This review summarizes the effects of clinical and subclinical hypothyroidism on fetal neurodevelopment, behavior and cognition in humans and rodents. Arch Endocrinol Metab. 2020;64(1):89-95

title: Effects of Hypoxia on Heart Rate Variability in Healthy Individuals: A Systematic Review

description: Abstract Background: Hypoxia is a physiological condition that may affect the cardiac autonomic modulation, which can be assessed by spontaneous fluctuations in heart rate, know as heart rate variability (HRV). Studies have reported reductions or maintenance of HRV in hypoxic situation presenting controversial effects. There is a knowledge gap in relation to changes in HRV during hypoxia. Objective: The aim of this study was to systematically review the effects of hypoxia on HRV in unacclimatized healthy adults at rest. Methods: This systematic review was performed according to PRISMA guidelines. Search terms used in MEDLINE, SCOPUS, LILACS and EUROPE PMC database were: "heart rate variability" OR "cardiac autonomic modulation" OR "cardiac autonomic regulation" AND NOT intermittent NOT sleep (hypoxia OR altitude). Records were filtered by species, age group and language. Results: At the end of the screening and eligibility, 13 manuscripts remained for qualitative synthesis. Discussion: The studies used different experimental protocols involving difference in barometric pressure, oxygen level, time of exposure to hypoxia and control of respiratory rate. Possibly the influence of these factors and also the interindividual variation to hypoxia may justify different responses in HRV. Conclusion: Based on the investigated studies, hypoxia has been capable of generating a decrease in HRV, either by reduction or maintenance of vagal modulation, or by sympathetic predominance or even the combination of these responses in healthy adults unacclimatized to hypoxia. This effect appears to be dependent on altitude level and barometric pressure. (Int J Cardiovasc Sci. 2017;30(3):251-261)

title: Is biochemical hypoglycemia necessary during an insulin tolerance test?

description: ABSTRACT Objective The insulin tolerance test (ITT) has been accepted as the gold standard test for assessing the integrity of the growth hormone (GH) – insulin-like growth factor (IGF-1) axis and the hypothalamic-pituitary-adrenal (HPA) axis. The goal of the test is to achieve clinical and biochemical hypoglycemia at a blood glucose level ≤ 40 mg/dL to effectively and correctly assess the HPA and GH-IGF-1 axes. In this study, the GH and cortisol responses of patients who achieved and failed to achieve biochemical hypoglycemia during an ITT were compared. Subjects and methods One hundred thirty-five patients with pituitary disorders were included in the study. Samples for blood glucose levels were obtained after clear symptoms of clinical hypoglycemia developed. The patients were enrolled in the hypoglycemic and nonhypoglycemic groups according to whether their plasma glucose level ≤ 40 mg/dL or &gt; 40 mg/dL during an ITT, and the groups were compared in terms of their GH and cortisol responses. Results The mean age, body mass index and waist circumference of the two patient groups were found to be similar. The mean blood glucose level was significantly lower in the hypoglycemic group than in the nonhypoglycemic group (19.3 and 52.0 mg/dL, respectively). When the two groups were compared in terms of peak cortisol and GH responses, no statistically significant differences were found. Conclusion The data presented suggest that clinically symptomatic hypoglycemia is as effective as biochemically confirmed hypoglycemia during an ITT. Arch Endocrinol Metab. 2020;64(1):82-8

title: In Vitro Rooting and Multiplication of Myrcianthes pungens (O. Berg) D. Legrand

description: Abstract The propagation of guabijuzeiro (M. pungens) by seed is originating plants with high genetic variability and a long juvenile period. Therefore, the objective was to study the multiplication and rooting in vitro of guabijuzeiro in order to get information to enable the clonal propagation. In the multiplication, apical and nodal segments were used, taken from in vitro plantlets, combined with 6-Benzylaminopurine (BAP), naphthaleneacetic acid (NAA) and gibberellic acid (GA). In the rooting, NAA and IBA (indolebutyric acid) were used. The results showed that in the multiplication there was superiority in media with BAP, while rooting was not satisfactory in media with NAA or IBA. Thus, it is possible to multiply M. pungens in vitro using BAP phytoregulator in the multiplication stage. However, the rooting stage needs more tests to induce the production of roots and facilitate acclimatization of the plants obtained in vitro.

title: Effect of Sample Dimensions on Static Bending Test

description: Abstract This study aimed to evaluate the static bending strength (fM) and modulus of elasticity (MOE) to static bending values of Eucalyptus grandis samples produced in different dimensions. It intended to identify samples that present similar mechanical properties to those recommended by other technical standards and those obtained according to NBR 7190. The samples were made in agreement with the dimensions of the following standards: IPT, AFNOR B51-016, ASTM D143, CEN-EN 408, COPANT 555, and NBR 7190. The strength was significantly reduced with the increase of the sample dimensions. The MOE was significantly influenced by the samples size with the values showing a parabolic trend. The samples produced according to COPANT 555 (5 x 5 x 75 cm) presented resistance values similar to the values obtained following NBR 7190 specifications, whereas for the MOE, the samples proposed according to the IPT presented the closest values of Brazilian technical standards (NBR 7190).
