Effects of a Methylcholanthrene-Induced Lymphosarcoma on the Blood of DBA/1J Mice

Description: This investigation was concerned with characterizing a tumor line induced and maintained in this laboratory. Various chemical assays, cell counts, and electron microscopy were the methods employed to characterize the blood of mice bearing the tumor at days 3, 6, 9, and 12 after injection of the 1.2 x 10^8 tumor cells.

The Recombination Rate Coefficient of Molecular Helium Ions in a Pulsed Afterglow at 1.86 Torr

Description: The recombination rate coefficient for molecular helium ions has been measured in a pulsed afterglow at 1.86 Torr as a function of electron temperature and electron density without making a priori assumptions about the functional dependence. The concentrations of the molecular ions and electrons were measured and the source terms for the molecular ions were included in the rate equation.

Some Acute Effects of X-Irradiation (LD100) on Plasma and Adrenal Tissue Histamine in Rats

Description: The effects of a lethal dose (1380 r) of X-irradiation on plasma and adrenal tissue histamine levels of rats were studied. The plasma histamine response was triphasic (increase at 1-3 hours, decrease at 5 and 9 hours and return to control at 24 hours post-irradiation). The adrenal tissue histamine response was found to be biphasic (decrease at 1 to 9 hours and a return to control level at 24 hours post-irradiation).

A Probabilistic Model for Evaluating Capital Investment Proposals for Petroleum Refineries

Description: The purpose of this study was to develop a probabilistic model that could be used by petroleum refiners to evaluate the economic potential of refinery capital investment proposals. The following two requirements were placed on the development at the outset: (1) that the model use linear programming to simulate refinery operations; and (2) that the model keep computer time within reasonable bounds. A probabilistic model was developed that requires the following steps for its application: (1) use… more
