 | Relaxor ferroelectric materials based on lead zinc niobate (PZN) are candidate materials for IR sensors in night vision equipment. Pyroelectric measurements, as well as measurements of the dielectric constant versus temperature and frequency, were performed. Crystallographic and grain size data are also presented. The peak temperature for the dielectric constant differs from that of the pyroelectric coefficient contributing to a high figure of merit for a pyroelectric IR detector material. ... |

|
| Inventory booklets were administered to Medical Administrative incumbents during the fall of 1979. Responses were received from 2,444 Medical Administrative incumbents (75 percent of the total assigned population). The overall sample was representative and provided a comprehensive picture of the 906XO population. The overall job structure was found to be extremely diverse, with 16 major job groups being identified. These jobs varied greatly. They ranged from routine jobs, such as ... |

|
| The data used in the compilation of this report were collected through the administration of job inventory booklets to all DAFSC 275XO personnel Air Force-wide. The survey results were based on responses from 380 of the 545 275X0 personnel assigned worldwide, or 70 percent of the total worldwide career ladder population. Overall, the career ladder structure was very homogeneous. All three major job clusters identified, Junior Tactical Air Command and ... |
