Astronomy in the region 1-0.1mm wavelengths

Measurements in five different passbands in the spectral region below 20/cm were made with a liquid helium-cooled radiometer in two flights at approximately 40 km altitude. The equivalent temperatures are given for passbands of 1 to 5.4, 7.8, 7.9, 11.1, and 18.5/cm. The results are consistent with a 2.7 K thermal radiation background. Atmospheric radiation of uncertain magnitude dominates the region above 11/cm

FLEXIBILITY IN AGRICULTURE

This paper considers the determinants of two dimensions of flexibility, the flexibility in adjusting aggregate output over time ("tactical flexibility") as well as the ability to switch quickly between products ("operational flexibility"). Econometric analysis of a sample of 40,000 farms in Upper-Austria for the period 1980 to 1990 suggests that larger full-time farms operated by younger, better educated farm operators are more flexible, ceteris paribus. The results further indicate a significant and negative interrelationship between tactical and operational flexibility.Farm Management, Industrial Organization,

Results of the 1983 NASA/JPL balloon flight solar cell calibration program

The 1983 solar cell calibration balloon flight was successfully completed and met all objectives of the program. Thirty-four modules were carried to an altitude of 36.0 kilometers. The calibrated cells can now be used as reference standards in simulator testing of cells and arrays. Cell calibration data are tabulated as well as the repeatability of standard solar cell BFS-17A (35 flights over a 21-year period)

Results of the 1984 NASA/JPL balloon flight solar cell calibration program

The 1984 solar cell calibration balloon flight was successfully completed on July 19, meeting all objectives of the program. Thirty-six modules were carried to an altitude of 36.0 kilometers. The calibrated cells can now be used as reference standards in simulator testing of cells and arrays
