1. A Gravimetric Approach to the Standard Addition Method in Instrumental Analysis 1
Published: Date unknown
Authors: William R. Kelly, Bruce S MacDonald, William F Guthrie
Abstract: A general mathematical formulation for the method of standard additions is presented that has universal applicability. It is based on gravimetry rather than volumetry which reduces the preparation time, gives greater flexibility to design because on ...

2. A Survey of Key Comparisons
Published: 1/1/2005
Authors: Adriana Hornikova, William F Guthrie
Abstract: Key Comparisons are international inter-laboratory studies used to establish the degree of equivalence between national measurement standards. These studies, carried out by National Metrology Institutes, are time-consuming, but necessary to facilita ...

3. A Survey of Key Comparisons A Survey of Design, Analysis, and Reporting of Results in Key Comparisons
Published: Date unknown
Authors: Adriana Hornikova, William F Guthrie
Abstract: Key comparisons are international inter-laboratory studies used to establish the degree of equivalence between national measurement standards. These studies, carried out by National Metrology Institutes (NMIs), are time-consuming, but necessary to fa ...

4. An Approach to Combining Results From Multiple Methods Motivated by the ISO GUM
Series: Journal of Research (NIST JRES)
Published: 8/1/2000
Authors: M Levenson, D L. Banks, K Eberhardt, L M. Gill, William F Guthrie, Hung-Kung Liu, M Vangel, James H Yen, Nien F Zhang
Abstract: The problem of determining a consensus value and its uncertainty from the results of multiple methods or laboratories is discussed. Desirable criteria of a solution are presented. A solution based on the ISO Guide to the Expression of Uncertainty i ...

6. CD Reference Materials for Sub-Tenth Micrometer Applications
Published: 6/1/2002
Authors: Michael W Cresswell, E. Hal Bogardus, Joaquin (Jack) Martinez, Marylyn H. Bennett, Richard A Allen, William F Guthrie, Christine E. Murabito, B A am Ende, Loren W. Linholm
Abstract: Prototype linewidth reference materials with Critical Dimensions (CDs) as narrow as 70 nm have been patterned in (110) silicon-on-insulator films. The sidewalls of the reference features are parallel, normal to the substrate surface, and have almost ...

9. Calcium Phosphate Cement With Non-Rigidity and Strength Durability for Periodontal Bone Repair
Published: 8/1/2006
Authors: Hockin D. Xu, Shozo Takagi, Limin Sun, L A Hussain, Laurence Chung Lung Chow, William F Guthrie, James H Yen
Abstract: Background. The need for biomaterials to treat periodontal osseous defects has increased as the world population ages. The objective of the present study was to develop a self-hardening, resorbable, and mech/anically strong calcium phosphate cement ...

10. Cell Seeding into Calcium Phosphate Cement
Published: 3/1/2004
Authors: Carl GEORGE Simon Jr, William F Guthrie, Francis W Wang
Abstract: We have sought to improve calcium phosphate cement by developing a method for seeding bone cells into the cement. Calcium phosphate cement (CPC) is a dry white powder of calcium phosphate salts that when mixed with water will react to form microcrys ...
