Why Intelligent Design Fails: A Scientific Critique of the ...
during the downstroke-upstroke transition. The downstroke pushes the wine
surface down through the air, which produces a forward thrust and generates lift.
The upstroke moves the folded wing into the raised position for the next
downstroke.

Textbook of Cardiovascular Medicine
The 'a' wave associated with right atrial systole occurs after the P wave and just
before the upstroke of the carotid pulse. Normally, 'a' wave is dominant and
appears more obvious during inspiration. During simultaneous palpitation of the
...

A delayed upstroke (pulsus parvus et tardus) suggests aortic stenosis, any left
ventricular outflow obstruction or any significant decrease in stroke volume.
Vascular sti›ness due to aging can reduce the delay, causing a more normal
feeling ...

Posture, Locomotion, and Paleoecology of Pterosaurs
The rotation of the humerus, imparted by the supracoracoideus muscle, rapidly
elevates the distal wing during the upstroke. Although we concur with Hazlehurst
and Rayner that the pterosaur humerus could rotate considerably, we also ...

Animal Physiology: Adaptation and Environment
As would be expected, these muscles are very large, constituting roughly 15% of
the body mass, irrespective of species or size of the bird. The muscles
responsible for the upstroke of the wing constitute only about one- tenth of the
total mass of ...

Therefore, the upstroke LEV has no influence on the formation of the downstroke
LEV which develops smoothly on the extra- dos, forming a high lift generating low
pressure region. Figure 8 shows the adimensional vorticity flow fields at time ...

Preferred Movement Patterns in Cycling: It's the Skill That ...
The trunk pelvic roll prepares each leg for the downstroke and upstroke
simultaneously. The TPR provides an integral mechanism for reversal of
movement; and this facilitates the transition from the backsweep to the upstroke.
The important ...

Sucker-Rod Pumping Manual
Although they are usually driven in either of the two possible directions, the small
differences in the upstroke and downstroke crank angle ranges can mean greater
differences in rod loads and torques. Therefore, the preferred direction of ...

Principles of Animal Locomotion
increases, the wings still move forward and backward relative to the body but the
path of the upstroke relative to the air becomes vertical (at 2.9 m/s) or inclined
forward (at higher speeds). The angular speeds ofwing movement relative to the
