On the Calibration of Cascade Impactors

Description: From Abstract: "In the following paper, the two customary methods of calibrating cascade impactors are compared. It is shown that the method of determining collection efficiency as a function of particle size for each stage provides information for interpreting results in terms of impactor theory, making it possible to establish adequate jet performance."

Operating Characteristics of the Lauterbach and Dautrebande Aerosol Generators

Description: From Abstract: "The air flow through the jet, the effect of a pre-humidifier on the water vapor content of the jet air, the cooling effect of the jet air on the generator solution, and the amount of water vapor carried away by the jet air were also determined and the results are discussed."

Flora of Healthy Dogs: [Part] 2. Isolation of Enteroviruses from Lower Intestines

Description: Fecal specimens from apparently healthy dogs were inoculated into MK, DK, HeLa, and CP cells. Twenty-six cytopathic agents were isolated in MK, 11 in HeLa, and 4 in CP, but none in DK cells. Neutralization tests indicated that all but one of the viruses were either strains of ECHO type 6 or were closely related to it. Twenty-one of 29 dogs were carrying the virus.

Procedures and Equipment Used in Inhalation Studies on Small Animals

Description: From Introduction: "These facts prompted the initiation of an effort to develop appropriate exposure equipment. The purpose of this communication is first, to describe an apparatus which, with modifications, allows pertinent information to be obtained on each individual small animal exposed and secondly, to set forth the pre- and post-exposure procedure adopted for obtaining required quantitative data regarding respiration, deposition. distribution and excretion."

The Stage Constants of Cascade Impactors

Description: From Introduction: "In the present work, the relationship between the true MMD's calculated in this way and the MMD's which could be obtained from a microscope analysis has been determined. This has been done to establish that the comparison being made gives a valid representation of what could be encountered in practice. The comparison has then been extended to cover a wide range of particle size distributions for three different impactors."

Data Procurement and Processing for the Fission Product Inhalation Program Using an Automatic Read Out Counting System

Description: Report describing the materials and procedures used to obtain data necessary "for correlation with the biological effects of inhaled mixed fission products" -page 1. The study is primarily focused on the biological effects of radioactive materials inhaled by animals and the materials taken from these animals and tested with computers.

Response to Secondary Antigenic Stimulus After Whole Body X-Irradiation in the Beagle

Description: From Abstract: "The results of the administration to healthy beagles of a secondary antigenic stimulus (booster dose) of Leptospira canicola and infectious canine hepatitis virus (ICH) are reported." From Introduction: "The results, using animals immunized with leptospira and infectious canine hepatitis virus (ICH) and exposed to x-irradiation, are reported."
