16 Connelly flexed his fingers and toes and felt renewed pain, a feeling of weightlessness.

17 There are sailors sleeping next to the engine room of ships and astronauts sleeping in weightlessness.

18 But thinness, as opposed to slimness, also carries connotations of weightlessness and emptiness.

19 It's based on the technology that was developed to help astronauts cope with weightlessness.

20 A primary purpose of the nine-day flight was to have been gathering evidence on how the human body adapted to weightlessness.

21 To apply engineering Methods : To the study of astronaut adaptation to weightlessness.

22 Flexibility and posture of spacesuit are indicated with human mechanics ( including weightlessness ).

23 In 1951, more than 10 years before the first human space flight, an expert in aviation medicine tried to predict some of the medical effects of space travel and, in particular(), of weightlessness.

24 As you perfect this technique, the dead point will begin to feel like an instant of weightlessness.

25 The astronauts will soon get used to the condition of weightlessness.

26 Current data showed that lowering of orthostatic tolerance after prolonged weightlessness is most likely due to change of baroreceptor reflex function.

27 It tested instruments for controlling a vehicle in the weightlessness of space.

28 Objectives : To investigate the microflora in rats gastrointestinal under simulated weightlessness.

29 No cardiac arrhythmia was found in hypoxia group. Conclusion Hypoxia is more effective in counter measuring orthostatic intolerance after weightlessness than Qigong.

32 AIM: To investigate the effect of rotating clinostat simulated weightlessness on the expression of differentiation related substances in rat osteosarcoma osteoblast like cells (ROS17/2.8).

33 In weightlessness, a drop of liquid takes a spherical shape.

34 Conclusion High frequency vibration can counteract the changes in expression of MHC in intrafusal and extrafusal fibers of rats soleus under muscles of rats in simulated weightlessness situation.

35 Stephen G. Bowen of the Navy, a former submariner, and Piers J. Sellers, a British-born astronaut who arranged to carry a piece of bark from Isaac Newton's apple tree into the weightlessness of space.

36 One of the many important aspects of preflight training will be to make sure that passengers are fully prepared for weightlessness, indeed, perhaps not even too excited about it.
