Extended amplification of acoustic signals by amphibian burrows
(Springer Verlag, 2016)
© 2016, Springer-Verlag Berlin Heidelberg.Animals relying on acoustic signals for communication must cope with the constraints imposed by the environment for sound propagation. A resource to improve signal broadcast is the ...
Underwater sound emission as part of an antipredator mechanism in Ceratophrys cranwelli tadpoles
(Wiley Blackwell Publishing, Inc, 2014-07)
We report the emission of underwater sounds in the tadpoles of a second member of the family Ceratophryidae, Ceratophrys cranwelli. These tadpoles produce a short metallic-like sound, which consists of short trains of ...
Tadpoles of the horned frog Ceratophrys ornata exhibit high sensitivity to chlorpyrifos for conventional ecotoxicological and novel bioacoustic variables
(Elsevier, 2018-04)
Previous studies reported that some species of the family Ceratophryidae are able to produce sounds during premetamorphic tadpole stages. We have now determined the effects of the cholinesterase-inhibiting insecticide ...
Moisture content and its influence on the roughness and noise emission during wood machining
(2015)
Numerous factors influencing the surface quality of wood after machining, among them we highlight the machining parameters and the properties of the wood. In the analysis of the influence of these factors on machining and ...
Dissociation and ionization in sonoluminescence
(Physical Soc JapanTokyoJapão, 2001)
Optimal linear control design applied to the synchronism of vocal folds with asymmetric stiffness
(Univ Estadual Maringa, Pro-reitoria Pesquisa Pos-graduacao, 2020-01-01)
The emission of sounds is an important means of communication between animals, which helps them to find a partner, establish their territory, and even alert other members of a population about a possible threat. In human ...
Remote Sensing Detection of atmospheric pollutants using Lidar, Sodar and correlation with air quality data in an industrial area
(2011-11-17)
Optical remote sensing techniques have obvious advantages for monitoring gas and aerosol emissions, since they enable the operation over large distances, far from hostile environments, and fast processing of the measured ...
