1. Autonomic heart rate modulation in patients with coronavirus disease 2019 in mechanical ventilation
SUMMARY BACKGROUND: Patients with coronavirus disease 2019 on automatic mechanical ventilation have greater heart rate modulation with greater parasympathetic modulation. OBJECTIVE: To analyze the autonomic modulation of heart rate in critically ill patients with coronavirus disease 2019 on invasive mechanical ventilation. METHODS: A cross-section study w

2. Estimation and Mapping of the Received Power Level of Digital Signals TV Using Spatial Interpolation Methods
Abstract The signal digitization process of the open television system is still in progress, therefore, the study of the digital signal propagation has great importance so that broadcasters can develop and improve the transmission service. The field measurement of digital signal parameters is one of the most reliable means to analyze the signal propagation i

3. Comparison of the autonomic nervous system dysfunction between different chronic spine disorders: neck pain versus low back pain
SUMMARY OBJECTIVE: This study aims to compare heart rate variability (HRV) between patients with chronic neck pain and patients with chronic low back pain and to correlate the chronic pain variables with heart rate variability indices. METHODS: This is a cross-sectional study. We divided the sample into two groups: neck pain (n=30) and low back pain (n=30)

4. Spatial Interpolation Techniques to Map Rainfall in Southeast Brazil
Resumo A previsão, assim como a estimativa de precipitação, é um dos desafios da comunidade científica no mundo, devido à alta variabilidade espacial e sazonal deste elemento meteorológico. Para tanto, metodologias que permitam a interpolação precisa desses elementos são de fundamental importância. Assim, buscamos avaliar a eficiência dos método

6. Temporal stability of stratifications using different dendrometric variables and geostatistical interpolation
RESUMO A estratificação de uma floresta resulta em inventários mais precisos e mais baratos. Este estudo teve como objetivo selecionar a variável estratificadora que estima inventários mais precisos e estáveis ao longo dos anos para um plantio de eucalipto no estado de Minas Gerais, Brasil. Foi realizado inventário florestal contínuo na área anualme

7. Two-dimensional spatial distribution modeling of sprinkler irrigation
ABSTRACT Irrigation can provide significant agronomic and financial returns on agricultural activity. The maximization of the benefits obtained from irrigation depends, among other factors, on the water use efficiency, which is intrinsically related to application uniformity. For the sprinkler method, the irrigation uniformity assessment is based on results

8. Limnological layers improve species distribution modeling of aquatic macrophytes at fine-spatial resolution
ABSTRACT Species distribution modeling (SDM) studies of aquatic macrophytes are still attached to methodological paradigms focused on terrestrial plants, such as the use of bioclimatic layers. Our goal was to evaluate the applicability of this paradigm based on a SDM study of Egeria densa, Pontederia crassipes, and Salvinia auriculata in the São Francisco r

9. CLIMATE ZONING FOR THE CULTIVATION OF AFRICAN MAHOGANY SPECIES IN BRAZIL
ABSTRACT African mahogany is the common name given to different species of the genus Khaya. They are tree species native to the African continent, which have a wood quality that allows their noble use in making fine furniture, and in the civil and naval industries. Currently, African mahogany cultivation has received notoriety in Brazil and given its climati

10. Two-dimensional beams in rectangular coordinates using the radial point interpolation method
Abstract The three-dimensional Theory of Elasticity equations lead to a complex solution for most problems in engineering. Therefore, the solutions are typically developed for reduced systems, usually symmetrical or two-dimensional. In this context, computational resources allow the reduction of these simplifications. The most recognized methods of algebraic

11. Emerging hotspots of tree richness in Brazil
ABSTRACT We present a summary of floristic variation and distribution of richness of tree and tree-like taxa (i.e., freestanding plants that reach at least 3m in height) in Brazil. We investigated composition patterns throughout phytogeographic domains and vegetation types based on 698,490 occurrence records obtained from the NeoTropTree (NTT) database, and

12. Data processing within rows for sugarcane yield mapping
ABSTRACT: The mapping of sugarcane yield is still not as widely available as it is for grain crops. Sugarcane harvesters cut and process the cane in a single or maximum of two rows, facilitating the monitoring of cane yield and its behavior on a small scale. This study tested a method for sugarcane yield data cleaning, investigating if the data recording fre
