monoclonal antibodies include onesthat discriminate between the ScuPA and the HMW form. A combination of these molecular-specific antibodies willenable simultaneous assays of the ScuPA,HMW, and LMW forms in the same spec-imen of culture medium.

The materials included in the collec-tion of documents describe the researchof the NASA Ames Fatigue Countermea-sures Group (FCG), which examines theextent to which fatigue, sleep loss, andcircadian disruption affect flight-crew performance. The group was formed in

1980 — in response to a Congressionalrequest to examine a possible safety problem of uncertain magnitude due totransmeridian flying and a potentialproblem due to fatigue in association

 with various factors found in air-trans-port operations — and was originally called the Fatigue/Jet Lag Program.The goals of the FCG are: (1) the devel-opment and evaluation of strategies formitigating the effects of sleepiness andcircadian disruption on pilot perform-ance levels; (2) the identification andevaluation of objective approaches for

the prediction of alertness changes inflight crews; and (3) the transfer and ap-plication of research results to the oper-ational field via classes, workshops, andsafety briefings.

Some of the countermeasure ap-proaches that have been identified to be

scientifically valid and operationally rele- vant are brief naps (
