Influence of the grinding wheel's dive speed on the damage of rectified hardened steels
(Univ Fed Rio de Janeiro, Lab Hidrogenio, 2008-01-01)
The world tendency is the increase of the productivity and the production of pieces more and more sophisticated, with high degree of geometric and dimensional tolerances, with good surface finish and low cost. Rectification ...

Buoyed up and slowed down: Speed limits for diving birds in shallow water
(Inter-Research, 2010-03)
In air-breathing animals, the time and energy costs of each dive are primarily determined by depth-related upthrust, swim speed and temperature. While studies have previously investigated how animals should optimise their ...
Diving classification and behavior of free-ranging female southern elephant seals based on threedimensional movements and video-recorded observations
(Inter-Research, 2019-06-18)
The goal of this study was to classify dives of free-ranging female southern elephant seals Mirounga leonina from Península Valdés, Argentina, during their 2 mo post-breeding migration. Classifications were based on ...
Flexible paddle sheds new light on speed: A novel method for the remote measurement of swim speed in aquatic animals
(Inter-Research Science Center, 2008-12)
Speed is a key determinant of energy expenditure in free-living animals, and particularly in marine vertebrates, where power requirements for swimming increase as a cubed function of the speed. However, current devices ...
Options for modulating intra-specific competition in colonial pinnipeds: the case of harbour seals (Phoca vitulina) in the Wadden Sea
(PeerJ, 2015-06)
Colonial pinnipeds may be subject to substantial consumptive competition because they are large, slow-moving central place foragers. We examined possible mechanisms for reducing this competition by examining the diving ...
Diving behaviour of the critically endangered tope shark Galeorhinus galeus in the Natural Reserve of Bahia San Blas, northern Patagonia
(BioMed Central, 2014-07)
Background:Tope sharks (Galeorhinus galeus) aggregate in large numbers during spring and summer in closedgulfs and bays in northern Patagonia; these locations are considered the main nursery areas for the species.However, ...
Influência da velocidade de avanço do rebolo nos danos de aços endurecidos retificados
(Rede Latino-Americana de Materiais, 2008-01-01)
A tendência mundial é o aumento da produtividade e da produção de peças cada vez mais sofisticadas, com elevado grau de tolerância geométrica, dimensional, com bom acabamento superficial, com baixo custo. A retificação é ...
