Seismic risk of sliding ground-mounted rigid equipment
(2020)
This study discusses a general formulation for risk assessment of ground-mounted rigid sliding equipment and contents during earthquakes. The displacement and acceleration response of blocks during earthquakes and risk ...
Aromatic character of O h -C 24 N 24 . A cavernous nitride fullerene bearing N 4 -macrocycle motifs
(John Wiley and Sons Inc., 2019)
A spherical treadmill system to train head-fixed adult rats
(Elsevier Science, 2018-03)
Background While spherical treadmills are widely used in mouse models, there are only a few experimental setups suitable for adult rats, and none of them include head-fixation. New method We introduce a novel spherical ...
Spherical episodic ejection of material from a young star
(2001-05-17)
The exact processes by which interstellar matter condenses to
formyoung stars are of great interest, in part because they bear on
the formation of planets like our own from the material that fails
to become part of the ...
Desenvolvimento de um material compósito cerâmico para aplicação em mancais porosos
(Universidade Federal de Minas GeraisUFMG, 2007-03-16)
Unlike contact roller bearings, air bearings utilize a thin film of pressurized air to provide a zero friction load bearing interface between surfaces that would otherwise be in contact with each other. Being non-contact, ...
On the bulk modulus and natural frequency of fullerene and nanotube carbon structures obtained with a beam based method
(Elsevier, 2018-03)
In this work, the natural frequency of vibration and Bulk modulus under hydrostatic pressure conditions of carbon nanotubes and fullerenes are investigated. For this purpose, three-dimensional finite element modelling is ...
