While it is relatively easy to place the transducer at the right spot on the abdomen when the subject is at rest (as on the RC), it is more difficult to place the transducer when the subject is suspended in the sling system (as on the SC), and also when the subject contracts his abdominal muscles with maximum voluntary contraction (as on the APC), so that the abdomen is deformed.
For concentric loading conditions, the subject contracted against an immovable resistance to the specified %GRFv identified via visual and auditory feedback.
As the subject contracts the muscle, the number and amplitude of the lines increases; as the muscle relaxes, it decreases.
From this position the subject contracts the abdominal muscles and sits up to touch his knees with his elbows.
For measuring upper arm circumference flexed (biceps circumference) the subject contracts muscle biceps as much as possible, and the tape is passed around the arm so that it touches the skin surrounding the maximum circumference.
Second, if subjects contract their muscles in a reactive manner (as on the SC) or in a voluntary manner (as on the APC), it is difficult for them to reproduce the same level of contraction across several days [ 15].
I am now writing a second book on this subject, Movies on Appeal, and I will be examining a second tier of legal topics or subjects (contract law, property law, the law of war, labor law) and how they are treated in mass culture.
If the subjects contracted the disease, they were given antibiotics.
Still, how could American researchers stand by silently while their subjects contracted the virus?
In 1952 he conducted field tests of his killed-virus vaccine, first on children who had recovered from polio and then on subjects who had not had the disease; both tests were successful in that the children's antibody levels rose significantly and no subjects contracted polio from the vaccine.
