Tissue residues of dieldrin in relation to mortality in birds and mammals Tissue residues of dieldrin in relation to mortality in birds and mammals

An experiment was performed with Coturnix to learn what residue levels were indicative of death from dieldrin poisoning. Birds were fed diets containing 250, 50, 10, and 2 ppm dieldrin for periods up to 158 days. The dieldrin was 95% pure HEOD, which is 1,2,3,4,10,10-hexachloro-6, 7.epoxy. l,4,4a,5,6,7,8,8a-octahydro-l,4-endo,exo-5,8- dimethanonaphthalene. When half of a group was dead...

Paleomagnetism, potassium-argon ages, and geology of rhyolites and associated rocks of the Valles Caldera, New Mexico Paleomagnetism, potassium-argon ages, and geology of rhyolites and associated rocks of the Valles Caldera, New Mexico

Paleomagnetic and potassium-argon studies support geologic evidence that the lower member of the Bandelier Tuff was deposited 1.4 m.y. ago. The upper member erupted about 1.0 m.y. ago and was followed by caldera collapse which formed the 12- to 14-mile diameter Valles Caldera. Postcaldera activity which resulted in the eruption of rhyolite domes and pyroclastic material, has occurred at...

Chapter 3: Television observations from Surveyor VII Chapter 3: Television observations from Surveyor VII

Surveyor VII, the last spacecraft of the Surveyor series, successfully landed at 01:05:36 GMT, January 10, 1968, on the outer rim flank of the large crater Tycho, in the southern part of the Moon. The spacecraft landed about 30 hours after local lunar sunrise and transmitted about 21,000 pictures during the remainder of the first lunar day of operation. On January 22, after local sunset...

Chapter IX: Lunar theory and processes Chapter IX: Lunar theory and processes

Whereas the previous Surveyor missions were undertaken to examine mare surfaces as potential landing areas for the Apollo Program, the primary objective of the Surveyor VII mission, based on purely scientific motivations, was to explore a contrasting highland region and, specifically, to determine the chemistry of the highland material for comparison with the Surveyor V and VI chemical...

Chapter 3: Television observations from Surveyor VI Chapter 3: Television observations from Surveyor VI

Surveyor VI landed on the lunar surface at 01:01:05 GMT on day 314 (November 10, 1967) in the southwestern part of Sinus Medii near the center of the visible face of the Moon. Over 30,000 pictures were transmitted from the spacecraft during the first lunar day of operation. The number of pictures taken by Surveyor VI almost equals the total number of pictures returned from the previous...
