Leaching and Precipitation Tests on Grants Ores (open access)

Leaching and Precipitation Tests on Grants Ores

Leaching tests were run on two samples from the Grants area in New Mexico. Uranium extractions of 94 per cent were obtained by leaching Sample 6-1 with solutions containing 240 lbs. of Na2CO3 and 60 lbs. of NaHCO3 per ton and by leaching Sample 6-2 with 270 lbs. of Na2CO3 and 180 lbs. of NaHCO3 per ton. Cyclic tests were completed using caustic precipitation of the leach liquor.

Prayer and Religion in the Public Schools: What Is, and Is Not, Permitted (open access)

Prayer and Religion in the Public Schools: What Is, and Is Not, Permitted

Few areas of constitutional law have proven to be as controversial and as subject to misinterpretation as that concerning the constitutionality of government-sponsored religious activities in public schools. In the last three decades the Supreme Court in five decisions and the State arid lower Federal courts in dozens of related decisions have attempted to articulate the 1 / meaning of the religion clauses of the First ~mendment- for a variety of such activities, including State-sponsored prayer, Bible reading, and religious teaching. Notwithstanding continuing political controversy over many of these decisions, they provide a fairly consistent interpretation and application of the First Amendment.

Evaluation of Experiment Off-gas System for the EGCR-LITR Capsule Experiment (open access)

Evaluation of Experiment Off-gas System for the EGCR-LITR Capsule Experiment

A proposed modification to the experiment off-gas system for the EGCR-LITR Capsule Experiment is evaluated by comparing the atmospheric radiation doses to laboratory personnel that could result in the event of an experiment failure while utilizing the present off-gas system to those doses that would result if various modifications to the existing system were effected. The modifications considered include the addition of an iodine vapor adsorber and a krypton-xenon adsorber. The addition of an iodine vapor adsorber to the off-gas system, which presently includes an absolute filter, reduces the atmospheric dose to the thyroid from 510 mr to 1.4mr. The total body dose is also reduced from 2.2 to 1.3 mr. The total body dose can be further reduced to 0.7 mr if a large krypton-xenon adsorber is included. Basd upon these calculated atmospheric radiation doses it is concluded that the addition of an activated charcoal iodine vapor adsorber will reduce the atmospheric hazard to an acceptable level.

Seismic Decoupling for Explosions in Spherical Cavities (open access)

Seismic Decoupling for Explosions in Spherical Cavities

Abstract. A series of paired explosions in a salt mine near Winnfield, Louisiana, has been conducted to test a theory by Dr. A. L. Latter concerning seismic decoupling by underground cavities. The theory predicted a decoupling of about 100. Free-field and surface measurements from an explosion in either a 6-ft- or a 15-ft-radius spherical cavity were compared with similar measurements from a completely tamped explosion. Shot sixes were from a 10 lb up to a few tons. Surface measurements were made out to 100 km and covered the frequency range from 0.05 to 100 cpa. The experiment confirmed that decoupling does occur. The actual decoupling factor as a function of frequency is presented and compared with the Latter theory.
