1. Bayesian modeling of the maximum streamflows from the Furnas reservoir
ABSTRACT The objective of this work was to predict the maximum flow of the Furnas reservoir in the dry and wet periods. The generalized distribution of extreme values (GEV) was used with parameter estimation via Bayesian inference. Data on average daily streamflows corresponding to the years 1965 to 2017 were obtained from Hidroweb, by the National Agency fo

2. A Parametric Study of Inductive SWIPT Systems Assisted by Metamaterial Using Virtual Magnetic TL-Based Channel Modeling
Abstract This paper presents a general methodology based on the description of the inductive channel as virtual magnetic transmission-lines (VMGTLs). In comparison with other existing methods, VMGTL approach presents a better physical insight of the channel behavior since the model correctly preserves the energy flow between the transmitting and receiving co

3. Numerical and experimental evaluation of the thermally stratified atmospheric boundary layer in wind tunnels
Abstract The atmospheric boundary layer (ABL) flow occurs due to the interaction between the Earth’s surface and atmosphere, and it usually happens under thermal stratification. Therefore, in order to emulate this phenomenon, atmospheric wind tunnels need appropriate devices, such as spires and cubical roughness elements, at the entrance of the wind tunnel

4. Comparative study of inclusion removal from liquid steel in the RH and argon purging processes
Abstract In order to improve steel quality, it is necessary to increase the cleanliness of the liquid steel; that is, to reduce the number and size of the inclusions in the liquid steel, as well as to control their chemical composition. For this purpose, processes (with different operating costs) are used, such as the bubbling of inert gas in the steel ladle

5. Rheological behavior of plant-based beverages
Abstract The aim of this research was to study the rheological behavior of a plant-based beverage made of Brazil nut (Bertholletia excelsa) and Baru (Dipteryx alata Vogel) and a nut-based beverage made of Brazil nut (Bertholletia excelsa) and Macadamia (Macadamia integrifolia) at the temperatures of 25, 45 and 80 °C. Experimental data were adjusted to the m

6. KINETIC MODELING AND EXPERIMENTAL VALIDATION OF A PHOTOCATALYTIC FLUIDIZED BED REACTOR FOR n-HEXANE DEGRADATION
Abstract This work presents a modeling procedure for a tall photocatalytic fluidized bed photoreactor used for the photocatalytic oxidation of n-hexane on the anatase TiO2 surface. The modeling strategy split the reactor into two parts: a lower dense phase, with high solids concentration behaving as a bubbling bed treated as a continuous stirred tank reactor

8. Leverage and investment opportunities: the effect on high growth firms
RESUMO O objetivo deste trabalho é investigar se o alto crescimento da firma resultará em redução do nível de dívida. Espera-se que isso aconteça para firmas que sofrem choque idiossincrático positivo nas suas oportunidades de crescimento, o que afetará seu fluxo de caixa e sua lucratividade. Embora a relação entre oportunidades de crescimento (e.

9. Dinâmica do desmatamento na Amazônia e seus impactos na hidrologia: bacia do Rio Machadinho - Rondônia / Brasil
Resumo A bacia hidrográfica do rio Machadinho é um exemplo de ocupação desordenada presente na região amazônica, na qual foram desmatadas grandes áreas com consequente conversão da floresta em pastagens e em núcleos urbanos. O presente trabalho tem o objetivo de analisar os impactos na hidrologia (vazão, precipitação e evapotranspiração) da bac

10. Regionalization of hydrological model parameters for the semi-arid region of the northeast Brazil
ABSTRACT This work deals with the regionalization of parameters of hydrological models in semi-arid regions with data scarcity, focusing on part of the Brazilian semi-arid region that involves the States of Ceará, Rio Grande do Norte, Paraíba and Pernambuco. The hydrological model adopted was the MODHAC - Self-Calibrating Hydrological Model. A total of 45

11. SEASONAL DYNAMICS OF AGRICULTURAL SOIL COVER IN RUNOFF GENERATION
ABSTRACT Seasonal changes in agricultural soil use due to agroclimatic conditions affect the water cycle in watersheds. This study aimed to understand the temporal variation of runoff inherent to the seasonal occupation dynamics of the agricultural soil in the basin that drains the upper valley of the Marrecas River, upstream of the urban perimeter of Franci

12. MATHEMATICAL MODELLING AND IMMEDIATE AND LATENT QUALITY OF NATURAL IMMATURE COFFEE UNDER DIFFERENT DRYING CONDITIONS
ABSTRACT This work aimed to study the immediate and latent effects of different relative humidities on the quality of dried coffee fruits, describe the drying kinetics of natural immature coffee (Coffea arabica L.), and evaluate the mathematical model that best fits the experimental drying data. The drying was carried out in a fixed layer dryer coupled to a
