Considering the importance of the proper detection of bubbles in financial markets for policymakers and market agents, we used two techniques described in Diba and Grossman (1988b) and in Phillips, Shi, and Yu (2015) to ...

The acoustic field in the liquid within a spherical solid shell is calculated. The proposed model takes into account Stoke?s wave equation in the viscous fluid, the membrane theory to describe the solid shell motion and the ...

Experimental data from the phase transition of the ternary systems {CO2(1) + [0.25 monoethanolamine(2) + 0.75 ethanol(3)]}, {CO2(1) + [0.25 diethanolamine(2) + 0.75 ethanol(3)]} and {CO2(1)+ [0.25 triethanolamine(2) + 0.75 ...

Aims. Aiming at studying the physical properties of Galactic IR bubbles and to explore their impact in triggering massive star formation, we perform a multiwavelength analysis of the bubble Hii region Sh2-39 (N5) and its ...

Aims. We perform a multiwavelength analysis of the bubble HII region Sh2-39 (N5) and its environs with the aim of studying the physical properties of Galactic IR bubbles and exploring their impact in triggering massive ...

O objetivo desse trabalho é apresentar e discutir a determinação dos parâmetros de dispersão de ar em células mecânicas de flotação, em circuitos industriais brasileiros. Foram investigados os circuitos rougher e scavenger ...
