Acoustic communication, broadly distributed along the vertebrate phylogeny, plays a
fundamental role in parental care, mate attraction and various other behaviours. Despite its …

The influence of applied tensile stress and grain size on Magnetic Barkhausen Noise and
hysteresis loops in 1005 commercial steel is studied in this work. The peak amplitude of the …

This work aims to characterize vibration behavior of roller bearings as a function of lubricant
viscosity. Experimental tests were performed in NU205 roller bearings, lubricated with …

The nondestructive Magnetic Barkhausen Noise (MBN) technique was applied for the
evaluation of SAE 4140 and SAE 6150 steels after a Jominy end-quench test. Microstructures …

In rolling bearings, contamination of lubricant oil by solid particles is one of the main reasons
for early bearing failure. In order to deal with this problem, it is fundamental not only the use …

The magnetic behaviour of most commercial ferromagnetic steels is usually anisotropic
presenting a magnetic easy axis. Changes in the direction of this axis can be related to …

This study presents a model of the microstructural defect influence on the magnetic Barkhausen
noise in plain steels. The comparison of the theoretical and experimental results reveals …

The Atlantic sector of the Southern Ocean (ASSO) has one of the highest densities of Antarctic
krill (Euphausia superba) compared to other polar and subpolar regions, which attracts …

As industrial activities continue to grow on the Brazilian coast, underwater sound measurements
are becoming of great scientific importance as they are essential to evaluate the impact …

The movement of magnetic domain walls can be disturbed by material defects, also named
pinning sites. When the magnetic field is changing, the domain walls move by “jumps” over …
