1. Be sure to ventilate on the upstroke.

2. He couldn't be careful enough on that upstroke.

3. Phase II is the expiratory upstroke.

4. The difference in the peak load on the upstroke and the minimum load on the downstroke of a polished rod.

5. During the course upstroke, the membrane potential attains zero, and an electrical gradient no longer exists.

6. In just six seconds he was moving seventy miles per hour, the speed at which one's wing goes unstable on the upstroke.

7. If the power shift pressure decreases, the pump will upstroke in order to increase the output of the pump.

8. The lines that formed the letters started again each time on the upstroke, the downstroke, and before the curves and loops.

9. A counterbalance is used on most pumpers to balance the weight of oil and sucker-rod string on the upstroke and the sucker-rod string on the down stroke.

10. The flow fields are different for the three phase motion patterns and there are two types of leading-edge vortex motion at an earlier stage of upstroke or downstroke.

11. The working principle and characteristics of hydrostatic transmission system with secondary regulation were introduced. The new system can match power perfectly during upstroke and down stroke.

12. Effleurage massage on upper legs should have more pressure on the upstroke.

13. So, when a bird banks right, its left wing moves faster on the downstroke while the right is faster on the upstroke, which slows the animal's rotation.

13. Sentencedict.com is a sentence dictionary, on which you can find good sentences for a large number of words.

14. The fluid above the traveling valve moves one full stroke upward on the upstroke.

15. The thrust force is mainly due to the drag of the wings in the upstroke.

16. Neither sodium valproate nor Verapamil showed any effect on action potential amplitude, overshoot, resting potential and phase O upstroke velocity.

17. Modern birds use a similar bone in flight, drawing their wings toward their bodies during an upstroke.

18. The peak polished rod load occurs near the bottom of the stroke with the start of the upstroke.

19. Then, every time, his left wing stalled on an upstroke, he'd roll violently left, stall his right wing recovering, and flick like fire into a wild tumbling spin to the right.

20. For example, birds clap their wings together at the peak of the upstroke during takeoff — that's the clatter of a pigeon taking off in the park — and rotate their wings on the way down to get lift.
