Chapter 154. Choline | Properties and Determination

January 1, 2016
Author(s)
Melissa M. Phillips
Choline is an essential nutrient that is required for normal cell function, with involvement in numerous cellular processes. Choline can be produced via de novo biosynthesis, but must be complimented with dietary intake to support optimum health. Foods

Cyber-Physical Social Systems: Getting People into the Loop

January 1, 2016
Author(s)
Sulayman Sowe, Eric D. Simmon, Koji Zettsu, Frederic J. de Vaulx, Irena Bojanova
This paper outlines the need to effectively integrate people into the design of a new generation of Cyber-Physical Social Systems (CPSS) and proposes a Human Service Capability Description Model to do it.

Density measurements of compressed-liquid dimethyl ether + pentane mixtures

January 1, 2016
Author(s)
Stephanie L. Outcalt, Eric W. Lemmon
Compressed-liquid densities of three compositions of the binary mixture dimethyl ether (CAS No. 115-10-6) + pentane (CAS No. 109-66-0) have been measured with a vibrating U-tube densimeter. Measurements were made at temperatures from 270 K to 390 K with

Design of a breast phantom for quantitative MRI

January 1, 2016
Author(s)
Kathryn E. Keenan, Sheye O. Aliu, Lisa J. Wilmes, David C. Newitt, Ella F. Jones, Wen Li, Michael A. Boss, Nola M. Hylton
Purpose: We present a breast phantom designed to enable quantitative assessment of measurements of T 1 relaxation time, apparent diffusion coefficient (ADC), and other attributes of breast tissue, with long-term support from a national metrology institute

Growth of one-dimensional nanomaterials in the ETEM

January 1, 2016
Author(s)
Jonathan P. Winterstein, Renu Sharma
One-dimensional nanomaterials (nanowires and nanotubes) have a number of unique and interesting properties that have made them the subject of significant research for a wide range of applications. Electron microscopy is generally necessary for their

MEMS Nanopositioners

January 1, 2016
Author(s)
Jason J. Gorman
This book chapter provides a review of the state of the art for MEMS nanopositioners. The motivation for MEMS nanopositioners is presented with respect to the advantages of this technology compared to macroscale mechanisms and the novel applications that

NIST Time and Frequency Bulletin

January 1, 2016
Author(s)
Karen L. Hansen Lichtfuss
The Time and Frequency Bulletin provides information on performance of time scales and a variety of broadcasts (and related information) to users of the NIST services

Organohalogen contaminants and vitamins in Northern Fur Seals (Callorhinus ursinus) collected during subsistence hunts in Alaska

January 1, 2016
Author(s)
Jessica L. Reiner, Paul R. Becker, Jennifer M. Lynch, Amanda J. Moors, Jennifer M. Ness, Rebecca S. Pugh, Catherine A. Rimmer, John R. Kucklick, Matthew O. Gribble, Danielle Peterson, Jody Rhoderick, Jennifer Trevillian
During native subsistence hunts from 1987 to 2007, blubber and liver samples from 50 subadult male northern fur seals (Callorhinus ursinus) were collected on St. Paul Island, Alaska. Samples were analyzed for legacy persistent organic pollutants (POPs)

PLANETARY BOUNDARY LAYER MODELING AND TALL BUILDING DESIGN

January 1, 2016
Author(s)
Emil Simiu, Liang Shi, DongHun Yeo
Recent research into Planetary Boundary Layer (PBL) flows accounts for the difference between �neutral� and �conventionally neutral� flows. Of interest in structural engineering are �conventionally neutral� PBL flows, that is, flows affected by transport
