On the Calibration of Cascade Impactors
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."

From Introduction: "The purpose of this paper is first to present a positive, but initial, approach that has been taken to meet these requirements, and second to report in detail the ultramicro method developed and evaluated for determining serum bilirubin. Subsequent publications will set forth the techniques finalized for other biochemical constituents."
A Cascade Impactor Operating at Low Volumetric Flow Rates
Report describing a five-stage cascade impactor, which has four impactor stages in which round jets are used and a filter stage. The method of calibrating the device is described. The significance of the collection efficiency and wall losses with respect to sampling for mass distributions is discussed.
Operating Characteristics of the Lauterbach and Dautrebande Aerosol Generators
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."

From Abstract: "The importance of interspecies comparison in obtaining parameters for estimating hazards to man is discussed, using cesium metabolism as an example."
Flora of Healthy Dogs: [Part] 2. Isolation of Enteroviruses from Lower Intestines
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.
The Particulate State of Fission Products Released From Irradiated Uranium When Heated in Air: [Part ]1. Preliminary Results for I131, Te132, and Ru103
From Introduction: "The present study was initiated to provide data regarding the particulate state of fission products released from uranium heated in air. It was expected that the information gained in this work would be valuable in planning experiments in which animals would be exposed to aerosols of mixed fission products and in determining the feasibility of using the effluent from a fuel specimen melt-down or oxidation in such exposures."

Procedures and Equipment Used in Inhalation Studies on Small Animals
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
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."
