Environmental Speciation and Monitoring Needs for Trace Metal-Containing Substances from Energy-Related Processes

Abstract: This book presents the Proceedings of the DoE/NBS Workshop on Environmental Speciation and Monitoring Needs for Trace Metal-Containing Substances from Energy-Related Processes held at the National Bureau of Standards, Gaithersburg, MD, on May 18-20, 1981. The Workshop was sponsored by the Office of Health and Environmental Research, DoE, and the Office of Recycled Materials, NBS. The volume contains refereed papers submitted by 24 invited speakers, along with substantially complete text of the discussion following the papers, edited by the Co-chairpersons. The Proceedings address three major topic areas forming the overall objective of the Workshop: (1) what are the general and specific types of metal- or metalloid-containing substances occurring in energy-related process materials such as coals, oil shales, and waste products? (2) what are the current status and future prospects of element- and compound-specific measurement methods suitable for speciation of trace (ppm, ppb) metal- and metalloid-containing substances transmitted to the environment by energy-processing or waste cycling technologies? (3) for what toxic molecular forms of speciated process effluents should biological dose-response data be generated to assure reliable environmental impact and monitoring measurements? Main questions focused, on providing assurance that the speciation methods (or their development) fit basic bioassay criteria along with …

Evaluating Thermal Fire Detection Systems: English Units (open access)

Evaluating Thermal Fire Detection Systems: English Units

Abstract: This report presents a methodology for evaluating heat detection systems installed in buildings. Previous work for use primarily in designing new thermal fire detection systems was used as a starting point. The previous work was enhanced and supplemented to make it more useful for evaluating existing systems. The resulting equations were programmed into a user interactive computer program. This program is available in both BASIC and FORTRAN and will run on mainframes as well as personal computers. In addition, a modified version of the FORTRAN program was used to develop an extensive set of tables listing detector activation times for given building geometries, detector characteristics, and fire growth rates. These tables are useful for quick evaluation of alternative heat detector installations. Finally practical examples are included to illustrate the use of the tables and computer programs.

Possible Estimation Methodologies for Electromagnetic Field Distributions in Complex Environments (open access)

Possible Estimation Methodologies for Electromagnetic Field Distributions in Complex Environments

Abstract: The problem of measuring and characterizing complicated multiple-source, multiple-frequency electromagnetic environments is becoming more important and more difficult as electrical devices proliferate. This paper outlines three general approaches to the problem which are currently under investigation at the National Bureau of Standards. The three approaches are: 1) a statistical treatment of the spatial distribution of electromagnetic field intensities, 2) a numerical computation using a finite-difference (or lattice) form of the electromagnetic action functional, and 3) use of a directional probe to scan a volume. All three methods are still in the development stage, but each appears promising.

A Near-Field Array of Yagi-Uda Antennas for Electromagnetic Susceptibility Testing (open access)

A Near-Field Array of Yagi-Uda Antennas for Electromagnetic Susceptibility Testing

Abstract: In electromagnetic susceptibility testing of electronic equipment, the ideal incident field is a plane wave. To approximate this condition, a seven-element array of Yagi-Uda antennas has been constructed and tested at a frequency of 500 MHz. The element weightings are determined by a near-field synthesis technique which optimizes the uniformity of the field throughout a rectangular test volume in the near field of the array. The amplitude and phase of the electric field have been measured throughout the test volume with a short dipole probe, and the agreement with the theory is excellent.

A Radio-Frequency Power Delivery System: Procedures for Error Analysis and Self-Calibration (open access)

A Radio-Frequency Power Delivery System: Procedures for Error Analysis and Self-Calibration

Abstract: An expression is developed for net power delivered to a load in terms of the indicated forward and reflected power and the system S-parameters and reflection coefficients. The dual directional coupler is treated as nonideal with power reflections assumed between all ports. The system itself is used to evaluate the major S-parameter terms in net power computation, and uncertainty in the computed power is derived from origins in the power meter readings and incompletely known S-parameters.

A Theory of Mutual Impedances and Multiple Reflections in an N-Element Array Environment (open access)

A Theory of Mutual Impedances and Multiple Reflections in an N-Element Array Environment

Abstract: A general theoretical approach is formulated to describe the complex electromagnetic environment of an N-element array. The theory reveals the element-to-element interactions and multiple reflections within the array. From the formulation, it is found that the interaction between an excited element and an open-circuited element can be viewed as the sum of terms describing all possible signal paths within the array environment which start from the radiating element and terminate on the element under observation. Within all paths except the most direct one, multiple reflections between subgroups of elements take place. The resulting solution is highly structured and recursive and is discussed in detail in the text. Illustrative examples are provided to facilitate understanding of these ideas.

Tables of Industrial Gas Container Contents and Density for Oxygen, Argon, Nitrogen, Helium, and Hydrogen

Abstract: Custody transfer tables are presented for oxygen, argon, nitrogen, helium, and hydrogen. The tables are based on standard reference data previously compiled by the National Bureau of Standards. Two sets of tables are provided for each fluid. Tables in engineering units cover the range -40 to 130*F with pressures from 100 to 10,000 prig. Tables in SI units (density versus pressure and temperature) cover the range 200 to 370 K with pressures from 0.5 to 70 MPa. The tables in engineering units are designed to provide a means of determining the volume of gas at standard conditions contained in a tank given the volume of the tank and the pressure and temperature of the gas within the tank. The publication also includes four examples of use of the tables in calculating tank quantities.
