Standardization of 237Np

December 4, 2013
Author(s)
Lizbeth Laureano-Perez, Ryan P. Fitzgerald, Ronald Colle
The standardization of 237Np was investigated. The certified massic activity for 237Np was obtained by 4 liquid scintillation (LS) counting with correction for the 233Pa daughter using the CIEMAT/NIST efficiency tracing method using a 3H standard

Composition-Explicit Distillation Curves of Alternative Turbine Fuels

December 3, 2013
Author(s)
Raina V. Gough, Thomas J. Bruno
In recent years, environmental considerations, the potential for supply disruptions, and rising fuel prices have led to the development of turbine fuels produced from non-petroleum feedstocks. To determine the suitability of an alternative turbine fuel, it

Preliminary Reconnaissance of the May 20, 2013, Newcastle-Moore Tornado in Oklahoma

December 3, 2013
Author(s)
Erica D. Kuligowski, Long Phan, Marc L. Levitan, David P. Jorgensen
This is a report on the National Institute of Standards and Technology (NIST) reconnaissance to collect information on the performance of one critical facility and two educational facilities in the May 20, 2013, Newcastle-Moore tornado in Oklahoma. The

Testing Equality of Cell Populations Based on Shape and Geodesic Distance

December 3, 2013
Author(s)
Robert C. Hagwood, Javier Bernal, Michael W. Halter, John T. Elliott
Image cytometry has emerged as a valuable in-vitro screening tool and advances in automated microscopy have made it possible to readily analyze large cellular populations of image data. A statistical procedure to study homogeneity of such data is addressed

A Simulation Platform to Study Inter-BAN Interference

December 2, 2013
Author(s)
Kamran Sayrafian, John G. Hagedorn, Martina Barbi, Judith E. Terrill, Mehdi Alasti
A Body Area Network (BAN) is a radio standard for wireless connectivity of wearable and implantable sensor nodes that are located inside or in proximity to the human body. Many applications of BANs (e.g. physiological monitoring) require reliable

Certification of Elements in and Use of Standard Reference Material 3280 Multivitamin/Multielement Tablets

December 2, 2013
Author(s)
Gregory C. Turk, Katherine E. Sharpless, Steven J. Christopher, Danielle Cleveland, Russell D. Day, Stephen E. Long, Elizabeth A. Mackey, Anthony F. Marlow, Rick L. Paul, John R. Sieber, Rabia Oflaz, Laura J. Wood, Lee L. Yu, Rolf L. Zeisler, Stephen A. Wise, James H. Yen, E. Greene, J. Harnly, I-P Ho, Joseph M. Betz, R. Q. Thompson, Candace Jongsma
Standard Reference Material (SRM) 3280 Multivitamin/Multielement Tablets was issued by the National Institute of Standards and Technology (NIST) in 2009 and has certified and reference mass fraction values for 13 vitamins, 26 elements, and 2 carotenoids

Improved Determination of the Neutron Lifetime

December 2, 2013
Author(s)
Jeffrey S. Nico, A. T. Yue, Maynard S. Dewey, David M. Gilliam, G L. Greene, A. Laptev, William M. Snow, F. E. Wiefeldt
The most precise determination of the neutron lifetime using the beam method was completed in 2005 and reported a result of tau_n = (886.3 ± 1.2 [stat] ± 3.2 [sys]) s. The dominant uncertainties were attributed to the absolute determination of the fluence

Quantitative bottom-up proteomics depends on digestion conditions

December 2, 2013
Author(s)
Mark S. Lowenthal, Yuxue Liang, Karen W. Phinney, Stephen E. Stein
Accurate quantification is a fundamental requirement in the fields of proteomics and biomarker discovery, and for clinical diagnostic assays. To demonstrate the extent of quantitative variability in measurable peptide concentrations due to differences

A Simple Means for Reducing the Risk of Progressive Collapse

December 1, 2013
Author(s)
Yihai Bao, Hai S. Lew, Fahim H. Sadek, Joseph Main
A simple debonding technique is proposed to reduce or eliminate strain localization in reinforcing bars in the region of wide flexural cracks in RC beams, and as a result enhance the resistance of RC buildings to disproportionate collapse. In this study

Dynamic contact AFM methods for nanomechanical properties

December 1, 2013
Author(s)
Donna C. Hurley, Jason P. Killgore
This chapter focuses on two atomic force microscopy (AFM) methods for nanomechanical characterization: force modulation microscopy (FMM) and contact resonance (CR) techniques. FMM and CR methods share several common features that distinguish them from
