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."

Ultramicro Methods in Biochemistry: [Part] 1. General Consideration, [Part] 2. Procedures for the Determination of Serum Bilirubin

Description: 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."

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.

The Particulate State of Fission Products Released From Irradiated Uranium When Heated in Air: [Part ]1. Preliminary Results for I131, Te132, and Ru103

Description: 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

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."

Ultramicro Methods in Biochemistry: [Part] 5. A Comparison of the Ultramicro Determination of Phosphorus Using N-Phenyl-p-Phenylenediamine or 1-Amino-2-Naphthol-4-Sulfonic Acid, [Part] 6. The Determination of Serum Alkaline Phosphatase

Description: From Introduction: "The following report describes an ultramicro procedure using ANSA as reducing agent. The method is a modification of the method of Kaser and Baker (4). Results obtained with this method are compared to results obtained with the procedure of Dryer, Tammes, and Routh (2) adapted for ultamicro analysis (3). The latter method uses N-phenyl-p-phenylenediamine (NPPD) as the reducing agent."

Ultramicro Methods in Biochemistry: [Part] 7. The Determination of Plasma or Serum Urea Nitrogen, [Part] 8. The Determination of Serum Uric Acid, [Part] 9. The Determination of Serum Creatinine

Description: From Introduction: "This report describes the development of an ultramicro modification of the method of Chaney and Marbach which is reliable and remarkably suited to routine analysis in bulk."
