Study Objectives: Insomnia is a common problem that affects 9% to 15% of the population chronically. The primary objective of this study was to demonstrate that 8 weekly sessions of sleep restriction therapy of insomnia combined with hypnotic reduction instructions following a single session of sleep hygiene education would result in greater improvements in sleep and hypnotic use than sleep hygiene education alone. Methods: Forty-six men and women were recruited from a sleep medicine practice and randomly assigned to sleep hygiene education plus 8 weeks of sleep restriction and hypnotic withdrawal (SR+HW; n = 24), or a sleep hygiene education alone (SHE; n = 22) condition. Pre-randomization, all patients received a single session of instruction in good sleep habits (sleep hygiene education). Results: The SR+HW condition had greater improvements in hypnotic medication usage, sleep onset latency, morning wake time, sleep efficiency, and wake time after sleep onset (trend), than the SHE condition. Continued improvement was seen in TST in the SR+HW group at 6-month follow-up, and gains on all other variables were maintained at 6-and 12-month follow-up. Conclusions: These results provide evidence that more intensive treatment of insomnia (i.e., 8 sessions of SR+HW plus hypnotic withdrawal instructions) results in better outcomes than SHE alone.

Introduction. Valuable information about the behavior of the ionized layers in the upper atmosphere may be acquired during periods of solar eclipse, when ionizing radiation from the sun is varied gradually and smoothly over a 2‐hour period. If, as most recent studies indicate, the ionized layers in the upper atmosphere result primarily from various ionization reactions due to solar X rays in the wavelength region between 10 and 600 A [Friedman, 1960], removal by eclipse of the source of these radiations should have detectable effects upon the extent of ionization in the regions of the ionosphere. Modern radio techniques permit the study of ionospheric behavior in considerable detail, and experiments have been performed during past eclipses with the aid of ionosondes, riometers, and high‐frequency (HF) oblique‐sounding equipment.

Portions of the trajectory of the Vertical Balloon, AMR Test 6210, were monitored with the Madre radar from Chesapeake Bay Annex. Detection was accomplished via direct look.Post flight position data from AMR and the Madre data from the trajectory were combined to confirm the vertical pattern of the Madre antenna.
