NIST Micronutrients Measurement Quality Assurance Program Winter and Summer 2016 Comparability Studies: Results for Round Robin LXXIX and LXXX Fat-Soluble Vitamins and Carotenoids in Human Serum

March 16, 2017
Author(s)
Jeanice M. Brown Thomas, David L. Duewer
The National Institute of Standards and Technology coordinates the Micronutrients Measurement Quality Assurance Program (MMQAP) for laboratories that measure fat-soluble vitamins and carotenoids in human serum and plasma. This report describes the design

29Si NMR and SAXS investigation of the hybrid organic-inorganic glasses obtained by consolidation of the melting gels

March 15, 2017
Author(s)
Andrei Jitianu, Sylvian Cadars, Fan Zhang, Gabriela Rodriguez, Quentin Picard, Mario Aparicio, Jadra Mosa, Lisa C. Klein
This study is focused on structural characterization of hybrid glasses obtained by consolidation of melting gels. The melting gels were prepared in molar ratios of methyltriethoxysilane (MTES) and dimethyldiethoxysilane (DMDES) of 75%MTES-25%DMDES and 65

Fundamentals of Small Business Information Security

Author(s)
Celia Paulsen, Gregory A. Witte, Larry Feldman
This bulletin summarizes the information in NISTIR 7621, Revision 1: Small Business Information Security: The Fundamentals. The bulletin presents the fundamentals of a small business information security program.

Jetting of a shear banding fluid in a rectangular duct

March 14, 2017
Author(s)
Paul NMN Salipante, Charles A. Little, Steven D Hudson
We report on a jetting flow instability of shear banding worm-like micelle (WLM) solutions in microfluidic channels with rectangular cross-sections over an intermediate volumetric flow regime. Particle tracking methods are used to measure the three

Synchrophasor Data Quality Attributes and a Methodology for Examining Data Quality Impacts upon Synchrophasor Applications

March 14, 2017
Author(s)
Dhananjay Anand, Allen R. Goldstein, Alison Silverstein, Laurie Miller, Francis Tuffner, Yuri Makarov
Data from synchrophasor devices like phasor measurement units (PMU) is increasingly being used to enhance and improve power grid operations, analysis, and planning applications. However, PMU data often arrive at the application with a variety of data

MOBY Review at Fiducial Reference Measurements for Satellite Ocean Color, Frascati, Italy, Feb 21 to 23, 2017

March 13, 2017
Author(s)
Kenneth Voss, B. Carol Johnson, Mark A. Yarbrough, Stephanie J. Flora, Michael Feinholz, Darryl Peters, Terrance Houlihan, Sean Mundell, Sandy Yarbrough, Art Gleason
This talk provided an overview of the MOBY project and the work we are doing now to move the MOBY instrumentation forward into the future. This is the first of 4 talks we gave at this workshop on various aspects of the MOBY project. The values of the MOBY

Radiometric Metrology for Ocean Color

March 13, 2017
Author(s)
Bettye C. Johnson
This talk covered the topics of uncertainty terminology (in brief), radiometric comparisons, gave an illustration of a spectral radiance scale realization, and concluded with a word on satellite system vicarious calibration (SVC).

Enhancing the Efficacy of Cancer Therapy: Use of Small Molecule Inhibitors of DNA Glycosylases as Potential Drugs

March 12, 2017
Author(s)
Erdem Coskun, Aaron C. Jacobs, Nathan Donley, Marcus J. Calkins, Dorjbal Dorjsuren, David Maloney, Anton Simeonov, Pawel Jaruga, Amanda K. McCullough, M Miral Dizdar, R. S. Lloyd
Chemotherapy aims to destroy cancer cells by damaging their DNA. However, the overexpression of DNA repair proteins in cancer cells causes the removal of DNA lesions before they become toxic and thus leads to an increased DNA repair capacity resulting in

PEE-PEO Block Copolymer Exchange Rate Between Mixed Micelles is Detergent and Temperature Activated

March 10, 2017
Author(s)
Allen B. Schantz, Patrick O. Saboe, Ian T. Sines, Hee-Young Lee, Kyle J. M. Bishop, Janna K. Maranas, Paul Butler, Manish Kumar
We examine the kinetics of polymer chain exchange between mixed polymer-detergent micelles, a system relevant to the synthesis of protein-containing biomimetic membranes. Although chain exchange between polymer aggregates in water occurs too slowly to

Spin Excitations and the Fermi Surface of Superconducting FeS

CYCLE_D: NIST Vapor Compression Cycle Design Program, Version 5.1.1; Users Guide

March 9, 2017
Author(s)
Piotr A. Domanski, J S. Brown, Eric W. Lemmon
The CYCLE_D package simulates vapor compression refrigeration cycles that use pure refrigerants or blends of refrigerants. The model can simulate a basic subcritical or transcritical refrigeration cycle, both with or without a liquid-line/suction-line heat
