1. Health Professionals and the Dynamics of COVID-19 in Manaus during the First Wave
ABSTRACT A model is made for the dynamics of the transmission of the new SARS-CoV-2 coronavirus, which caused the COVID-19 pandemic. This model is based on the Susceptible-Infectious-Recovered model with heterogeneity in the susceptible population and in the infectious population. The susceptible population is divided into two subpopulations: individuals who

2. Strategies to increment in vivo and in vitro embryo production and transfer in cattle
Abstract Knowledge of follicular wave dynamics obtained through the use of real-time ultrasonography and the development of the means by which follicular wave dynamics can be controlled have provided practical approaches for the in vivo and in vitro production and transfer of embryos in cattle. The elective control of follicular wave emergence and ovulation

3. Sequence stratigraphy of fluvial to shallow-marine deposits: The case of the early Permian Rio Bonito Formation, Paraná Basin, southernmost Brazil
Abstract This study presents new sedimentology data and attempts to understand coastal processes, sedimentary dynamics and stratigraphic patterns of the Rio Bonito Formation (early Permian) in Paraná Basin, southern Brazil. The study was performed based on the description of five cores, located in a small-scale area - São Gabriel City - in Rio Grande do Su

4. Application of an alternative mesh morphing method on the numerical modeling of oscillating wave surge converters
RESUMO Uma das tecnologias capazes de explorar a energia das ondas, baseada na captação das componentes horizontais do movimento destas, aliada a um sistema placa-pistão, vem experimentando um notável desenvolvimento ao longo dos últimos anos, tal dispositivo é conhecido como conversor oscilante por translação de ondas. Este possui um grande potencia

5. Propagation of vibrational modes in classical harmonic lattice with correlated disorder
Abstract: The vibrational modes with nonzero frequency are localized in harmonic lattice with disordered masses. In our work, we investigated numerically the propagation of vibrational energy in harmonic lattice with long-range correlated disordered masses, which are randomly distributed with power law spectrum S ( k ) ∝ k − α. For α = 0, a standar

6. Genetic Population Structure and Allele Surfing During Range Expansion in Dynamic Habitats
Abstract: Expanding populations may loss genetic diversity because sequential founder events throughout a wave of demographic expansion may cause “allele surfing”, as the alleles of founder individuals may propagate rapidly through space. The spatial components of allele surfing have been studied by geneticists, but have never been investigate on dynamic

7. A Prediction Model for Night Recovery of Embarked Aircrafts Based on System Dynamics
ABSTRACT: In order to make a sensible prediction on the air traffic flow management with conditions of wave-off and bolter, a system dynamic model for the night recovery operations of embarked aircrafts is built to ensure the adaption of air traffic flow with the capacity of air control at each phase of the recovery operations. The model aims at the characte

8. Una revisión de literatura sobre el uso de sistemas de adquisición de datos para la enseñanza de la física en la educación básica, media y en la formación de profesores
This paper presents a literature review that approaches the current state of the data acquisition systems implementation in physics teaching; mainly at Middle and High School levels and in teachers training. The main search was performed in 35 journals found in the following databases: Science Direct, Scopus, Web of Science and Google Scholar, taking into ac

9. Ultrafast Dynamics of Au Nanopyramid Interfaces Prepared by Nanosphere Lithography: Effect of Substrate Chemical Composition
This work describes ultrafast spectroscopy studies of Au triangular pyramid particle arrays deposited over glass (termed Au/glass), and 190 nm indium tin oxide (ITO) film (termed Au/ITO/glass) prepared by nanosphere lithography. The linear absorption spectra of Au/glass and Au/ITO/glass exhibit surface plasmon resonances at 800 and 870 nm, respectively, in g

10. Estudo teórico da estrutura eletrônica e da dinâmica induzida por lasers da molécula de HCl
Potential energy and dipole moment curves for the HCl molecule were computed. Calculations were performed at different levels of theory (DFT, MRCI). Spectroscopic properties are reported and compared with experimental data, for validating the theoretical approaches. Interaction of infrared radiation with HCl is simulated using the wave packet formalism. The

11. Propagação guiada de ondas de VLF: aplicação ao estudo de fenômenos atmosféricos e naturais
Deep amplitude minima are observed in the daily records of Very Low Frequency (VLF, between 3 - 30 kHz) wave amplitudes. Amplitude minima are attributed to modal interference and modal conversion of waves propagating in the Earth - Ionosphere waveguide. The time of amplitude minima is related with the localization of the Terminator line and, therefore, is de

12. Plasma urea nitrogen and progesterone concentrations and follicular dynamics in ewes fed proteins of different degradability
The effects of overfeeding with protein of different degradability on body condition, plasma urea nitrogen and progesterone concentrations, ovulation number and follicular dynamics were assessed in Santa Ines ewes. Twelve ewes were assigned to a randomized block design according to body weight and received overfeeding with soybean meal or with corn gluten me
