It was an impression dispelled instantly by the bravura opening to the race, a thrilling mass dive-start followed by a jostling sprint for position in the main peloton.
Generalized linear mixed-effect models with the animal as the random variable and five explanatory variables (body mass, buoyancy, dive depth, dive phase, and drag) showed that swim speed was best predicted by two variables, drag and dive phase (AIC = −139).
We used a generalized liner mixed-effect model (GLMM) to determine interactions among swim speed (dependent variable) and five explanatory variables (body mass, buoyancy, dive depth, drag, and dive phase: descent or ascent phase) with individual identification as a random effect (family = Gaussian; link = identity).
The allometry of resting metabolic rate (RMR) on body mass in diving ducks (RMR = 446 m0.98 where m = mass is in kg and the RMR is in kJ day−1) [29] predicts a metabolic rate at rest of 3.49 W for ducks of the mean body mass of our ducks.
On the morning of 15 August 1939, during a mass-formation dive-bombing demonstration for high-ranking commanders of the Luftwaffe at Neuhammer training grounds near Sagan, 13 Ju 87s and 26 crew members were lost when they crashed into the ground almost simultaneously.
There was also no statistical relationship between depth of last foot stroke and body mass, independently of maximum dive depth (no interaction between body mass and maximum dive depth: F1,130 = 0.32, p = 0.574).
Even if BH-diving implies hyperbaric and consequently hyperoxic exposure, it should be remembered that during BH-diving, a mass of blood pools in the lungs as a result of the so-called blood-shift effect [2, 3].
I pace the length of the three Titanic stones of the wall of Baalbec, — mightiest masses of quarried rock that man has lifted into the air; and then I dive into some mass of foliage with my microscope, and trace the veinings of a leaf so delicately wrought in the painting not made with hands, that I can almost see its down and the green aphis that sucks its juices.
Monitoring of free dives has shown that the crocodilians exhibit two types of submergence behavior: long (∼12 min) resting dives, the duration of which depends on body mass, and short (∼1 min) active dives, which vary in length based on the animal's activities.
They huddled, struggled and bartered in the face of dive-bombers and mass hysteria.
Erin Stahmer's whipping arms opened the work, but soon the rest of the cast formed a mass of bodies; as one dived in, another popped out on the other side.
