Effects of Pressure on the Dynamics of an Oligomeric Protein from Deep-Sea Hyperthermophile

November 10, 2015
Author(s)
Utsab R. Shrestha, Debsindhu Bhowmik, John R. Copley, Madhu Sudan Tyagi, Juscelino Leao, Xiang-Qiang Chu
Inorganic Pyrophosphatase (IPPase) from Thermococcus thioreducens is a large oligomeric protein derived from a hyperthermophilic microorganism that is found near hydrothermal vents deep under the sea, where the pressure is up to 100 MPa (1 kbar). It has

Hydrogen Field Test Standard: Laboratory and Field Performance

November 10, 2015
Author(s)
Jodie G. Pope, John D. Wright
The National Institute of Standards and Technology (NIST) developed a prototype field test standard (FTS) that incorporates three test methods that could be used by state weights and measures inspectors to periodically test retail hydrogen dispensers, much

The Occurrence of Repeated Fiber Breaks in Microcomposites

November 10, 2015
Author(s)
Gale A. Holmes, Edward D. McCarthy, Nathanael A. Heckert, Stefan D. Leigh, Jae Hyun Kim, Jeffrey W. Gilman
The mechanical integrity of a structural composite is strongly affected by the strength and toughness of the fiber–matrix interface/interphase (Norwood, 1994), with interfacial shear strength (IFSS) considered the best quantifying metric. IFSS outputs are

A Case Study of a Community Affected by the Waldo Fire Event Timeline and Defensive Actions

November 9, 2015
Author(s)
Alexander Maranghides, Derek McNamara, Robert Vihnanek, Joseph Restaino, Carrie Leland
The National Institute of Standards and Technology (NIST) has a suite of research projects addressing risk reduction in Wildland Urban Interface (WUI) communities. This case study is focused on the Mountain Shadows Community (MSC) in Colorado Springs

Computer Evacuation Models for Buildings

November 9, 2015
Author(s)
Erica D. Kuligowski
N/A for SFPE Handbook Chapters. Included here is text from the chapter introduction: "With the rapid increase in computer capability and the increase in egress model development, there is a need for guidance on evacuation modeling, specifically the process

Using Semantic Web Technologies to Integrate Models to Analytical Tools

November 9, 2015
Author(s)
Peter O. Denno, Mark R. Blackburn
This paper discusses the potential advantages and pitfalls of using semantic web technologies in the process of preparing engineering analyses. Analytical tools are often not designed to be integrated with disparate information sources and general-purpose

MEASUREMENT OF DNA REPAIR PROTEINS IN RELATION TO DISEASE BIOMARKERS AND DRUG DEVELOPMENT

November 7, 2015
Author(s)
Erdem Coskun, Pawel Jaruga, Leona D. Scanlan, Alessandro Tona, Mark S. Lowenthal, Prasad T. Reddy, M Miral Dizdar, Ann-Sofie Jemth, Olga Loseva, Thomas Helleday
Introduction: In aerobic organisms, intracellular metabolism and exogenous sources such as ionizing radiation and carcinogenic compounds generate reactive species including free radicals derived from either oxygen or nitrogen. Oxidative stress thereby
