Detecting Cooling Coil Fouling Automatically-Part 1: A Novel Concept

July 1, 2010
Author(s)
Daniel A. Veronica
Fouling of surfaces within the heat exchangers of heating, ventilating, and air conditioning (HVAC) systems of buildings is an equipment fault that wastes appreciable amounts of energy, however, it escapes detection under current building automation

EMPS: Radiation Thermometer Designs

July 1, 2010
Author(s)
Howard W. Yoon, George P. Eppeldauer
Since the publication of the “Theory and Practice of Radiation Thermometry” in 1988, the designs of radiation thermometers have undergone drastic changes. With the exception of few industries, the disappearing filament pyrometers are not commonly used. The

High-voltage Nanoimprint Lithography of Refractory Metal Film

July 1, 2010
Author(s)
John A. Dagata, Natalia Farkas, R Ramsier
Local oxidation of metal, semiconductor, and polymer surfaces has provided a common basis from which to explore fundamental principles of nanolithography and prototype functional nanostructures for many years now. This article summarizes an investigation

IEEE 1451.5 STANDARDS-BASED WIRELESS SENSOR NETWORKS

July 1, 2010
Author(s)
Eugene Song, Kang B. Lee
Recent advances in wireless communications, networking, electronics, and microprocessors have enabled the development of low-cost, low-power wireless sensor nodes. Wireless sensor networks have become more widely used to monitor the condition of the

Optimizing the Conditions of a Multiple Reaction Monitoring Assay for Membrane Proteins: Quantification of Cytochrome P450 11A1 and Adrenodoxin Reductase in Bovine Adrenal Cortex and Retina

July 1, 2010
Author(s)
Illarion V. Turko, Wei-Li Liao, Gun-Young Heo, Nathan G. Dodder, Irina A. Pikuleva
Although 30% of naturally occurring proteins are predicted to be embedded in biological membranes, membrane proteins are traditionally understudied due to limitations of the available analytical tools. To be applicable to the analysis of membrane proteins

Passive terahertz camera for standoff security screening

July 1, 2010
Author(s)
Erich N. Grossman, Charles Dietlein
We describe the construction and performance of a passive, real-time terahertz camera based on a modular, 64-element linear array of cryogenic hotspot microbolometers. A reflective conical scanner sweeps out a 2 m ×4 m(vertical × horizontal) field of view

Preparation and Characterization of Standard Reference Material 1849 Infant/Adult Nutritional Formula

July 1, 2010
Author(s)
Katherine E. Sharpless, Richard M. Lindstrom, Bryant C. Nelson, Karen W. Phinney, Catherine A. Rimmer, Lane C. Sander, Michele M. Schantz, Rabia Oflaz, Jeanice M. Brown Thomas, Gregory C. Turk, Stephen A. Wise, Laura J. Wood, James H. Yen
Standard Reference Material (SRM) 1849 Infant/Adult Nutritional Formula has been issued by the National Institute of Standards and Technology (NIST) as a replacement for SRM 1846 Infant Formula, which was issued in 1996. Extraction characteristics of SRM
