Improvements in the Winkler Titration for Iodide in Iodized Salt

Author(s)

Kenneth W. Pratt, Karen E. Murphy

A bromine gas generator, based on bleach, potassium bromide and dilute hydrochloric acid, replaces hazardous pure bromine used in the classical Winkler titration for iodide. This modification eliminates the need to store or use pure bromine. The gas

In vivo testing of native a-conotoxins from the injected venom of Conus purpurascens

Author(s)

Frank Mari

α-conotoxins selectively inhibit nicotinic acetylcholine receptors (nAChRs) and have been used as probes to study cholinergic pathways in vertebrates. Drosophila melanogaster expresses nAChRs in the CNS and is a suitable model to investigate the effects of

Author(s)

Jussara Tanesi, Dale P. Bentz, Scott Z. Jones, Mengesha Beyene, Haejin Kim, Ahmad Ardani, Paul E. Stutzman

While the influence of paste properties on concrete performance has been extensively studied, that between aggregate characteristics and concrete performance has not been investigated in detail. Based on previous research that demonstrated significant

Inter-comparison Example

International Evaluation Collaboration: Developing and Managing Infrastructure for Research and Development Programs

Author(s)

Rachel J. Bowers, Dennis Moellman, John S. Garofolo

The most innovative technology can potentially meet any goals of research sponsors. However, this potential may never materialize if the program lacks infrastructure. Although most new programs address basic contractual and managerial components, often few

Is Bonds Out

Author(s)

Robert C. Hagwood

In this paper, the cumulative home run rates of the 20 players with 500 or more home runs are analyzed. We show that Bonds and McGwire have cumulative totals that lie statistically outside the others in the study.

Comments on the Draft of Supplement 0 to the Guide to the Expression of Uncertainty in Measurement (GUM), to be discussed during the April 2007 meeting of Working Group 1 of the Joint Committee for Guides in Metrolgy, BIPM, in Sevres, France.

Making Ballot Language Understandable to Voters

Author(s)

Sharon J. Laskowski, Janice G. Redish

The wording and placement of instructions can help or hinder voters from successfully voting for their choices. No research has been done specifically on the language of instructions to voters, but we can draw best practices from research in several

Metrology and process control: dealing with measurement uncertainty

Author(s)

James E. Potzick

Metrology is often used in designing and controlling manufacturing processes. A product sample is processed, some relevant property is measured, and the process adjusted to bring the next processed sample closer to its specification. This feedback loop can

Microsecond-Resolution Laser Polarimetry for the Measurement of the Normal Spectral Emissivity of Pulse-Heated Materials

Author(s)

Sitaraman Krishnan, K Boboridis

The design and operating principles of a new laser polarimeter system capable of microsecond-resolution measurements of the polarization state of light and of optical properties of solid and liquid materials, including the normal spectral emissivity, are

Mie 16-6 force field predicts viscosity with faster-than-exponential pressure dependence for 2,2,4-trimethylhexane

Author(s)

Richard A. Messerly, Michelle C. Anderson, S. M. Razavi, J. R. Elliott

In response to the 10th Industrial Fluid Properties Simulation Challenge, we report viscosity (eta) estimates of 2,2,4-trimethylhexane at 293 K for a range of pressures (P) from 0.1 MPa to 1000 MPa. The Potoff force field is utilized in this study, as a

Moving With Metric (draft title--metric system cube)

Author(s)

P A. Wolf

This information cube promotes the International System of Units (SI), or the metric system.The SI is the dominant system of measurement units worldwide. Developed by the French in the late 18th century, the system has been refined by international

Multiple Dimension Levenshtein Edit Distance Calculations for Evaluating Automatic Speech Recognition Systems During Periods of Overlapping Speech

Author(s)

Jonathan G. Fiscus, Jerome G. Ajot, Nicolas Radde, Christophe Laprun

Since 1987, the National Institute of Standards and Technology has been providing evaluation infrastructure for the Automatic Speech Recognition (ASR), and more recently referred to as the Speech-To-Text (STT), research community. From the first efforts in

Nanoparticle Release from Polymer Nanocomposites Used for Potable Water Infrastructure and Food Packaging: Current Progress & Beyond

Author(s)

Andrew Whelton, T.V. Duncan , J.L. Koontz , Tinh Nguyen

Nanoparticle (NP) enhanced polymers have the potential to revolutionize food packaging and water pipe performance, though release from these materials has gone relatively unstudied. A literature review was conducted to identify potential NP release

New NIST-traceable Standards for Calibration and Validation of Differential Scanning Calorimetry

Author(s)

Donald G. Archer

Several reference materials and associated reference values have been recommended for the purposes of calibration and/or validation of differential scanning calorimetry (DSC). However, issues of available sample purity, reference-property value accuracy
