Primary electric power generation systems for advanced-technology engines [PDF]
, 1983 The advantages of the all electric airplane are discussed. In the all electric airplane the generator is the sole source of electric power; it powers the primary and secondary flight controls, the environmentals, and the landing gear. Five candidates for

Lack of capture‐induced mortality of neonates associated with variation in handling protocols
Wildlife Society Bulletin, EarlyView.We found that handling metrics (e.g., handling time, number of collectors, and age at capture) had limited or no influence on the survival of neonatal mule deer, desert bighorn sheep, and Rocky Mountain bighorn sheep within the first few days of life. Furthermore, we found that handled mule deer and Rocky Mountain bighorn neonates were recruited at a ...
