Characterization of PADAP. [Quarterly report], July--September 1970

Description: A single batch (No. 4-60-IV) of PADAP supplied by Sandia Corporation was analyzed to determine its suitability for a specific detonator application. Results of 5 tests on the explosive are reported. From these tests, PADAP appears to be too insensitive for such detonators.

Chondrococcus columnaris disease of fishes: Influence of Columbia River fish ladders

Description: Mortalities in salmonid populations induced by Chondrococcus columnaris are usually associated with warm river water temperatures. Increasing use of the Columbia River for agriculture, industry and power will introduce additional added heat increments which could result,in additional growth of C. columnaris and proliferation of the disease. It is necessary, therefore, that we examine the existing environmental factors which contribute to the disease in the river. Proliferation and release of C. columnaris from fish ladders was demonstrated by the large number of organisms isolated from the Rocky Reach fish ladder on the Columbia River during 1965. The authors found that C. columnaris release into the water was related to the high incidence of infected coarse fishes and anadromous salmonids in the ladder. In this report, we will describe results which suggest that fish ladders may be important, sites for transferring the disease from fish indigenous to the Columbia River to migrating anadromous salmonids.

Detonation sphere. Quarterly report, April--June, 1970

Description: Evaluation of the test data from numerous experiments indicates that large scale calorimeter experimentation in the Pantex detonation sphere is impractical. Detailed quantitative and qualitative measurements of the detonation products will continue to be made to provide data for the evaluation and comparison of explosive performance.

Explosive performance. Quarterly report, January--March, 1970

Description: The objectives of the study are the determination of detonation velocity, shock sensitivity, impact sensitivity, etc.; and the acquisition of high precision one-dimensional hydrodynamic data for use in establishing detonation product equations of state, performance of explosives, etc. A one-inch diameter cylinder test was fired with LX-07-2 Lot HOL 902-1. A wedge test series on LX-07-1 was completed. Shock sensitivity appears to be less than for LX-10-0 but slightly higher than for LX-09-0. One snowball test was conducted with LX-07-2. It was discovered that a change in the detonators employed had occurred.

Explosive performance. Quarterly report, July--September, 1970

Description: The objectives of this study are the determination of detonation velocity, shock sensitivity, impact sensitivity, etc.; and the acquisition of high-precision one-dimensional hydrodynamic data for use in establishing detonation product equations-of-state, performance of explosives, etc. A wedge test series was begun on RX-25-AA. This is the first attempt in this work to study a composite explosive with the wedge test. Behavior appears to be quite different from the standard explosives.

HE friction sensitivity. Oblique impact sensitivity of explosives: The skid test and half-inch gap sensitivity test. Quarterly report, January--March, 1970

Description: Vertical drop tests were completed on several explosives. Results are given and discussed. Oblique impact tests were performed on the extrusion cast explosive RX-08-AZ. No reactions were observed in the severest of impacts. Half-inch gap test series were performed on two lots of LX-09-0. Results are tabulated. No experimental work with the friction test apparatus was done this period.

Large scale calorimeter experimentation. Quarterly report, January--March, 1970

Description: A number of PETN charges and one confined TNT charge were fired, and the product gases were analyzed by mass spectroscopy (at both LRL and Pantex; agreement was good). The investigation into the feasibility of large scale calorimeter experimentation on the Pantex detonation sphere continues; conclusions are not yet drawn.

Leptodea fragilis, Specimen #492

Description: One preserved mussel specimen including both the left and right valves. The specimen exhibits a rhomboidal shape; thin shell; double looped beak sculpturing; white internal coloring; tan external coloring; no external sculpturing. Collected in the Brazos basin. The specimen measures between 100 - 120 mm in length and was assessed to be long dead when collected.
