Fourth International Symposium on Roofing Technology

March 1, 1998
Author(s)
Walter J. Rossiter Jr
This report presents a summary of the Fourth International Symposium on Roofing Technology. The National Institute of Standards and Technology (NIST) Building and Fire Research Laboratory (BFRL) and the National Roofing Contractors Association (NRCA) have

Hyperfine Structure Constants for Diatomic Molecules

March 1, 1998
Author(s)
I Tupitsyn, Svetlana A. Kotochigova
The contact term A c of magnetic hyperfine parameters as a function of internuclear distance R was computed, using the all-electron Valence-Bond method, Hartzee-Fock atomic basis set and configuration-interaction wave functions. Parameters were calculated

Integration Strategies for the Reactive Scheduling System

March 1, 1998
Author(s)
David W. Thomas
Shop Floor operations can be optimized by scheduling applications that not only create an initial schedule but also allow feedback from data collection systems to enable re-scheduling. Interfaces required to integrate the various commercial applications

Multiple Fiber Technique for the Single Fiber Fragmentation Test

March 1, 1998
Author(s)
Chang K. Moon, Walter G. McDonough
The single fiber fragmentation test has been modified by embedding multiple fibers into matrix resin. During testing, we examined the interfacial shear strengths between the fibers and the matrix. In addition, the time-dependent nature of the fragmentation

National Semiconductor Metrology Program, Project Portfolio, FY 1998

March 1, 1998
Author(s)
Stephen Knight, A D. Settle-Raskin
The National Semiconductor Metrology Program (NSMP) is a NIST-wide effort designed to meet the highest priority measurement needs of the semiconductor industry as expressed by the National Technology Roadmap for Semiconductors and other authoritative

NIST Meeting on Multicomponent Polymers and Polyelectrolytes

March 1, 1998
Author(s)
Jack F. Douglas
A joint meeting was held between the NIST Polymer Blends and Processing Group and ERATO. The purpose of the conference was to review progress made by the NIST and ERATO groups in experimental and theoretical aspects of phase separation in polymer blends

NIST Methods for the Certification of SRM 1941a, Organics in Marine Sediment, and SRM 1974a, Organics in Mussel Tissue (Mytilus edulis)

March 1, 1998
Author(s)
Michele M. Schantz, Bruce A. Benner Jr, M K. Donais, M. J. Hays, William R. Kelly, Reenie M. Parris, Barbara J. Porter, Dianne L. Poster, Lane C. Sander, Katherine E. Sharpless, Robert D. Vocke Jr., Stephen A. Wise, M Levenson, Susannah B. Schiller, M Vangel
The replacement Standard Reference Materials [SRM 1941, Organics in Marine Sediment, and SRM 1974, Organics in Muscle Tissue [Mytilus edulis], have been prepared and analyzed for the determination of trace organic constituents. SRM 1941a has been issued
