Evaluation of microstructure and mechanical properties of M-SIMA processed Al–7Si alloy
In this research article, the effect of the strain-induced melt activation (SIMA) process on the microstructure and mechanical properties of the Al–7Si alloy has been investigated. The morphology of α-Al grains is changed from dendritic to fine spherical

Echolocation click parameters and biosonar behaviour of the dwarf sperm whale (Kogia sima)
Dwarf sperm whales (Kogia sima) are small toothed whales that produce narrow-band high-frequency (NBHF) echolocation clicks. Such NBHF clicks, subject to high levels of acoustic absorption, are usually produced by small, shallow-diving odontocetes, such ...
