title: Ownership Concentration and other Determinants of Covenants in Debt Contracts of Brazilian Publicly Listed Firms

description: ABSTRACT This article investigates whether the concentration of stock ownership affects the presence and intensity of covenants in the debt contracts of companies listed on the B3 stock exchange in the 2007-2018 period. We also present an overview of the presence and breach of covenants by these firms. For this purpose, we manually analyzed more than 4,000 explanatory notes for the firms’ financial statements regarding loans and financing and then applied linear and nonlinear regression models. We found that greater ownership concentration is associated with higher likelihood of the presence of covenants, corroborating the role of the ownership structure as a substitute governance mechanism that allows for aligning interests and reduces the need for using covenants. The results are useful to managers, creditors, and shareholders, by showing which characteristics are determinants of the use of covenants, supporting management of factors that can reduce their occurrence, and bring greater flexibility to the corporate decision-making process, directly maximizing the value to shareholders.

title: DEFINING, ORGANIZING AND REPRESENTING THE TERRITORY OF THE NATION. JOSÉ MARÍA REYES (1803-1864), TOPOGRAPHER AND GEOGRAPHER OF THE ORIENTAL STATE OF URUGUAY

description: Abstract Military engineer José María Reyes played a central role in the topographical and geographical knowledge of the territory of the Oriental State of Uruguay; he contributed to the process of internal departmentalization and participated as a commissioner in the delimitation of political borders, especially those with Brazil. He also prepared geographical maps, and dedicated himself to documentary compilation and writing descriptions of the territory. This task was not individual, but part of a path in which the Oriental State began an upward process of information collection through the creation of public entities dedicated to the maintenance of internal order, topographical surveys or health care, which sought to know characteristics and quantity of inhabitants, inventory public and private real estate, delimit the territories, and establish the main characteristics of productive development. Regional war conflicts and internal political life limited several of these tasks. Reyes was no stranger to the context; on the contrary, he was actively involved in political life, and several of his views were reflected in his geographical conception. On this basis, the article explores Reyes’ performance and the way in which his topographic and cartographic work contributed to forming a representation of the national territory, linked to a conception of the past that was subsequently reproduced by those who continued his work, establishing a geographical imaginary that lasts until the present.

title: MEXICO AND ITS “LIBERAL TRIENNIUM”: LIBERALISM, LOCAL POWER AND SUFFRAGE

description: Abstract The second constitutional moment that would take place in the Spanish monarchy from 1820 on had important consequences for the configuration of Mexico as an independent State. If, initially, the territory moved towards liberal political forms inserted in the monarchy as a whole, soon after, from 1821, Mexican independence would be proclaimed. This did not mean abandoning the liberal practices implemented from the application of the Constitution of 1812, but their extension in the initial stages of the independent nation. Based on the political projects of self-government that the Mexicans proposed in the Cortes of Madrid in these years, the establishment of constitutional town councils and the electoral practices that allowed a large part of the population to exercise suffrage, this work seeks to account for these changes that, inserted in the logic of Cadiz liberalism, transformed Mexico from viceroyalty into nation-state.

title: Sleep, nutritional status and eating behavior in children: a review study

description: ABSTRACT Objective: To review the current literature on the relationship between sleep, nutritional status and eating behavior, as well as mechanisms associated with these elements in children. Data source: The literature research was conducted in the PubMed, LILACS and Scopus databases, using the following terms: “Child”; “Nutritional status”; “Sleep”; “Physical activity OR Physical activities OR Exercise”. The articles included were those that met the research objective. Review articles, letters to authors, or guidelines were excluded. Data synthesis: 402 articles were initially found in the literature search. After careful analyses of the title and abstract, and application of inclusion criteria, only 24 studies were included in the present review. Most studies (n=13) suggest that short sleep duration (&lt;9-10 hours/night) is associated with overweight/obesity in children. Only three studies did not show associations between overweight/obesity and sleep variables. Short sleep duration is also associated with poor food quality, higher intake of soft drinks and stimulant beverages before bedtime, as well as micronutrient deficiency. Conclusions: Sleep duration is related to overweight and obesity development in infants. Changes in dietary pattern are also related to sleep debt, being one of the mechanisms that contribute to excessive weight gain. It is necessary that health professionals understand the importance of sleep quality in the nutritional status maintenance in children.

title: Natural ventilation as a tool for reducing the propagation of Covid-19 in classrooms

description: Abstract The Coronavirus pandemic aroused the academic community’s concern about indoor air quality. The main way of spreading the disease is through aerosols, with viruses present in particles that remain suspended in the air for long periods. This study seeks to understand the role of natural ventilation in the probability of contagion of the disease in classrooms. Ventilation rates were calculated by the algebraic method for classrooms in two situations: cross ventilation and unilateral ventilation. A reduction in the maximum occupancy of classrooms was proposed, considering a minimum distance of 2 meters between occupants, and maintaining a minimum ventilation rate of 27 m³/h per person. The probability of contagion was calculated for the original and reduced capacities of each room, following the methodology proposed in the literature. Each room was also classified according to its number of air changes per hour. Single-sided ventilation was insufficient to maintain adequate ventilation rates in all cases. For 11 out of the 31 rooms evaluated, a distance of 2 meters between occupants is insufficient to maintain adequate ventilation rates.

title: SPRAY NOZZLE WEAR EFFECTS ON DROPLET POPULATION

description: ABSTRACT The wear rate of spray nozzles affects several factors. This study aimed to investigate the influence of spray nozzle wear rate on droplet characteristics, such as droplet size, droplet homogeneity, droplets prone to drift, and flow rate variation. Eight hydraulic nozzles models (AIXR-110-02, JSF-110-02, TT-110-02, DG-110-02, XR-110-02, ADI-110-02, XR-110-02, and AI-110-02) were subject to an accelerated wear test, and their effects were measured at six experimental wear times (0, 10, 20, 30, 40, and 50 hours). The following variables were evaluated: volume median diameter, percentage of spray volume containing droplets smaller than 100 μm (prone to spray drift), flow rate (L min-1), and relative span, which indicates droplet size homogeneity. The droplet population was measured using a laser particle size analyzer. The use of the spray nozzle tip influences the quality of the spray application due to the wear rate. This study revealed a linear increase in the flow rate and volume median diameter as functions of the wear rate increment. The droplet size increased over the wear time, which consequently modified the volume percentage of droplets smaller than 100 μm and significantly increased the relative span.

title: Marble and granite waste as mineral addition in mortars with different water-cement ratios

description: Abstract Civil construction is associated with several environmental impacts, such as CO2emissions during cement production and waste generation. In this context, aiming to contribute to the sustainable development of the sector, this article aims to study the effect of replacing cement by marble and granite waste (MGW) in different water/cement ratios (w/c). To do this, the waste was characterized and applied in 1:3 mortars, replacing the cement at 20% content. Mortars with and without plasticizing additives were produced, measuring the amount of water by fixing the workability and the additive content. Water demand, compressive strength, dynamic modulus of elasticity, water absorption by immersion and capillarity, electrical resistivity and accelerated carbonation were evaluated. The results showed that the MGW acted as a filler, promoting refinement of the porous structure and maintenance of compressive strength due to better particle packing. It was observed that MGW made the mortar structure more homogeneous. However, the filler effect of the waste (inert) did not compensate for the reduction in the cement content of the mortars for strength to carbonation. In general, it was observed that waste is more efficient in lower water/cement ratios.

title: Efficiency and accuracy of different ovulation inducers after progesterone device removal in crossbred multiparous cows

description: Abstract The aim of this study was to verify the efficiency and ovulation time after the administration of different inducers for synchronization of ovulation in beef cows. One hundred and eight non-lactating cows were distributed into the control group (CG; untreated; n=28), estradiol benzoate (EB) group (EBG; n=28); 17 beta-estradiol (17ßE) group (17ßEG; n=28), and deslorelin (DES) group (DESG; n=24). On day minus 11 (D-11) of the protocol, the CG underwent application of cloprostenol and ultrasound examination (US); on D0, progesterone (P4) was inserted plus EB; on D7, cloprostenol was applied; on D9, P4 was removed and cloprostenol plus 400 IU of equine chorionic gonadotropin (eCG) was injected. The EBG was subjected to treatment identical to that of the CG, except on D10, when the cows received EB. The 17ßE was subjected to the same protocol used in the CG except for the administration of 17ßE on D10. And, the DESG was subjected to the same treatment as the CG, except on D10, when the group received DES acetate. Twelve hours after the administration of EB, 17ßE and DES, ovarian US were performed every 6 hours. The preovulatory follicle (POF) diameters measured before ovulation were 19.5; 14.7; 18.7 and 19.8 mm respectively for CG, EBG, 17ßEG and DESG; and the time intervals between inducer application and ovulation were 20.2; 18.9; 21.0 and 22.5 hours respectively. In conclusion, all ovulation inducers were efficient in promoting ovulation; the inducers caused ovulation between 18.9 and 22.5 hours; EB promoted ovulation in a shorter time (P&lt;0.05); 17ßE and DES showed greater variation in application/ovulation time between groups.

title: Rheological characterization of rhea (Rhea americana) eggs subjected to different storage periods

description: Abstract Eggs are used as food industry ingredients due to their functional properties. Eggs from different bird species are used in industrial processing; therefore, rheological experiments were carried out at steady state to obtain the flow curves and also at a dynamic state to study the rheological properties of greater rhea eggs. The viscoelastic behavior of the fluids as a function of the coagulation temperatures for albumen and yolk and of the oscillatory shear frequency was studied. Fifteen rhea eggs stored for up to 28 days at 10 °C were analyzed at 1, 7, 14, 21, and 28 days. The albumen and yolk fractions showed pseudoplastic rheological behavior with small initial flow shear and dependence on shear time, with albumen demonstrating thixotropy and the yolk showing rheopexy. In low shear rheological tests, thermal gelation of albumen was observed, presenting a first change in the elastic modulus around 56 °C, and a second from 78 °C. In the yolk, a change was observed from 66 °C, with more structural variations in the development of the gel at higher temperatures. For rhea eggs, the gel structuring (gelation) temperature of albumen (80 °C) and egg yolk (69 °C) did not undergo variations during the storage periods. Compared to commercial eggs, the higher viscosity and gelation temperatures presented by the rhea eggs can help determine the size of the industrial processing system as they can be submitted to higher temperatures without modifying protein structures and hindering the process.
