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."

Proceedings of Cryocooler Conference: 1984

Description: Abstract: This document contains the proceedings of the Third Cryocooler Conference, held at the National Bureau of Standards, Boulder, CO, on Sept. 17-18, 1984. About 140 people from 10 countries attended the conference and represented industry, government, and academia. A total of 26 papers were presented orally at the conference and all appear in written form in this document. The emphasis in this conference was on small cryocoolers in the temperature range of 4 - 80 K. Mechanical and non-mechanical types were discussed in the various papers. Applications of these small cryocoolers include the cooling of infrared detectors, cryopumps, small superconducting devices and magnets, and electronic devices.

Proceedings of the Conference on Accreditation of Construction Materials Testing Laboratories: 1986

Description: Abstract: A two-day Conference hosted by NBS was held in Gaithersburg, Maryland on May 14-15, 1986 to test the hypothesis that "There is a need for a coordinated methodology for accrediting construction materials testing laboratories." Construction materials include primary materials such as: cement, concrete, aggregates, rock and soil, asphalts, metals, wood and masonry. The Conference was structured to consider: (1) the status of existing laboratory evaluation and accreditation programs; (2) current trends in the accreditation process; and (3) the need for and nature of a coordinated accreditation system. The Conference included the presentation of invited papers and four workshop sessions.

Proceedings of the Eighth DOE Solar Photochemistry Research Conference Held at Interlaken Conference Center, Lake Geneva, Wisconsin, June 11-14, 1984

Description: These annual meetings bring together contractors of the Division of Chemical Sciences in its basic research program on solar photochemical energy conversion to exchange information and to give interested government officials an opportunity to assess the current status of the program. This year's meeting was joined by 12 Canadian scientists with similar interests in solar photochemistry. This volume contains the program of the meeting, a list of attendees, the abstracts of 29 formal presentations and 36 posters, and a record of questions and answers following each presentation.

Proceedings of the Focused Research Program on Spectral Theory and Boundary Value Problems, Vol. 2: Singular Differential Equations

Description: Report on research and exchange of views among 24 mathematicians for investigations of the theory of singular Sturm-Liouville equations, the asymptotic analysis of the Titchmarsh-Weyl m(λ)-coefficient, and the qualitative theory of non-linear differential equations.

Proceedings of the Second International Conference on Precision Measurement and Fundamental Constants, June 8-12, 1981

Description: Abstract: This volume presents the Proceedings of the Second International Conference on Precision Measurement and Fundamental Constants, held at the National Bureau of Standards in Gaithersburg, MD, from June 8-12, 1981. Like its 1970 predecessor, the Conference provided an international forum for theoretical, experimental, and applied scientists actively engaged in research on precision measurements relating to the fundamental physical constants, and on the testing of related fundamental theory. More specifically, the purpose of the Conference was to assess the present state of the precision measurement-fundamental constants field, to examine basic limitations, and to explore the prospects for future significant advances. The principal subjects covered were: frequency, wavelength, spectroscopy, quantum electrodynamics, the gas constant, x-ray interferometry, nuclidic masses, uncertainty assignment, gravitational acceleration, mass, electrical quantities, gravity, and relativity. These proceedings contain the vast majority of both the invited review papers and the contributed current research papers presented at the Conference. The new results reported at the Conference were considered for inclusion in the 1983 least-squares adjustment of the constants carried out under the auspices of the Task Group on Fundamental Constants of the Committee on Data for Science and Technology (CODATA).
