Influence of porosity on high-velocity mass-asymmetric collisions
(Wiley Blackwell Publishing, Inc, 2020-02)
Using granular mechanics, we study the influence of porosity on the collisions of spherical granular aggregates with a mass ratio of around 60. At high filling factors, the projectile produces a crater on the target, similar ...
Ethanol oxidation reaction on PtCeO(2)/C electrocatalysts prepared by the polymeric precursor method
(ELSEVIER SCIENCE BV, 2009)
This paper presents a study of the electrocatalysis of ethanol oxidation reactions in an acidic medium on Pt-CeO(2)/C (20 wt.% of Pt-CeO(2) on carbon XC-72R), prepared in different mass ratios by the polymeric precursor ...
Dispersed phase hold-up in a perforated rotating disc contactor (PRDC) using aqueous two-phase systems

Misaligned snowplough effect and the electromagnetic counterpart to black hole binary mergers
(2019-01-01)
We estimate the accretion rates produced when a circumprimary gas disc is pushed into the primary supermassive black hole (SMBH) by the tidal force of the decaying secondary during a SMBH merger. Using the 3D Smoothed ...
HERschel Inventory of The Agents of Galaxy Evolution (HERITAGE): The Large Magellanic Cloud dust
(2010)
The HERschel Inventory of The Agents of Galaxy Evolution (HERITAGE) of the Magellanic Clouds will use dust emission to investigate the life cycle of matter in both the Large and Small Magellanic Clouds (LMC and SMC). Using ...
Estrutura de sistemas de três corpos fracamente ligados em duas dimensões
(Universidade Estadual Paulista (Unesp), 2016-01-28)
Este trabalho foca no estudo de sistemas de poucos corpos em duas dimensões no regime universal, onde as propriedades do sistema quântico independem dos detalhes da interação de curto alcance entre as partículas (o comprimento ...
Terrestrial planet formation constrained by mars and the structure of the asteroid belt
(2015-01-01)
Reproducing the large Earth/Mars mass ratio requires a strong mass depletion in solids within the protoplanetary disc between 1 and 3 au. The Grand Tack model invokes a specific migration history of the giant planets to ...
Influence of size, variety and male female ratio in the production of tilapia (Oreochromis spp.) eggs in concrete tanks at the venezuelan andean foothills
(2021)
The aim of this study was examine the effect of the variety, size and male female ratio in the egg production of tilapia Chitralada (CH: Oreochromis niloticus) and Taiwanese Red (TR: O. mossambicus x O. niloticus) reared ...
