Firebrand Generation from Building Components with Cedar Siding

May 6, 2013
Author(s)
Samuel L. Manzello, Sayaka Suzuki, Yoshihiko Hayashi
Fires in the wildland-urban interface (WUI) have been a large problem not only in the USA, but all over the world. From a pragmatic point of view, the WUI fire problem can be seen as a structure ignition problem [1]. It is believed that the structures

The Forthcoming IEEE Standard 1696 on Test Methods for Characterizing Circuit Probes

May 6, 2013
Author(s)
Nicholas Paulter, John Jendzurski, Mike McTigue, Bill Hagerup, Thomas E. Linnenbrink
The Technical Committee 10 (TC10) of the IEEE Instrumentation and Measurement Society initiated a new standards activity in 2006 for the development of test methods to characterize the performance of circuit probes. This standard contains a set of

Viscosity Modifiers to Enhance Concrete Performance

May 6, 2013
Author(s)
Dale P. Bentz
The hazard rate function for concrete structures often is portrayed as a “bathtub”-shaped curve, with a finite ever-decreasing probability of early-age failures being followed by a life with a relative low, constant probability of failure that ultimately

Vulnerability of Decking Assemblies to Continuous Firebrand Shower

May 6, 2013
Author(s)
Samuel L. Manzello, Sayaka Suzuki
In WUI fires, decking assemblies have been observed to be an ignition vulnerability based on post-fire damage surveys. The Office of the State Fire Marshall (OFSM) in California adopted the test method known as State Fire Marshall (SFM) STANDARD 12-7A-4 [1

Structural design for fire conditions: reliability-based resistance criteria

May 4, 2013
Author(s)
Therese P. McAllister, Bruce Ellingwood
The new paradigm of performance-based fire engineering (PBFE), with its systematic approach to identifying building performance objectives, quantitative structural analysis to verify that these objectives have been achieved, and management of uncertainties

Studies of photoconductivity and FET behavior in examining drift mobility, surface depletion, and transient effects in Si-doped GaN nanowires examined in vacuum and air

May 3, 2013
Author(s)
Norman A. Sanford, Lawrence H. Robins, Paul T. Blanchard, K. Soria, B. Klein, Kristine A. Bertness, John B. Schlager, Aric W. Sanders
Variable intensity photoconductivity (PC) performed under vacuum at 325 nm was used to estimate drift mobility and negative surface charge density sigma for c-axis oriented Si-doped GaN nanowires (NWs). In this approach we assumed that sigma was

Synapsable quadruplex-mediated fibers

May 3, 2013
Author(s)
Veronika A. Szalai, Miguel A. Mendez
We have fabricated and characterized a novel DNA based nanofiber created by synergistic self-assembly of guanine quadruplex (Hoogsteen base pairing) and double-stranded DNA (Watson-Crick base pairing). The assembly of our nanofibers occurs in several steps

Towards Ontology Evaluation across the Life Cycle

May 3, 2013
Author(s)
Fabian M. Neuhaus, Amanda Vizedom, Ken Baclawski, Mike Bennet, Mike Dean, Michael Denny, Michael Gruninger, Ali Hashemi, Terry Longstreth, Leo Obrst, Steven R. Ray, Ram D. Sriram, Todd Schneider, Marcela Vegetti, Matthew West, Peter Yim
Currently, there is no agreed on methodology for development of ontologies, and there is no consensus on how ontologies should be evaluated. Consequently, evaluation techniques and tools are not widely utilized in the development of ontologies. This can

Assessment of the Thermophysical Properties of Thermally Stressed RP-1 and RP-2

May 2, 2013
Author(s)
Tara J. Fortin, Thomas J. Bruno
Density, speed of sound, and viscosity have been measured for samples of RP-1 and RP-2 that were stressed for 0.5 min at 475 °C and 510 °C at a pressure of 17 MPa. Density and speed of sound were measured from 5 °C to 50 °C for the samples stressed at 475

Nanosilver suppresses growth and induces oxidative damage to DNA in Caenorhabditis elegans

May 2, 2013
Author(s)
Bryant C. Nelson, Bryce J. Marquis, Piper R. Hunt, Katherine M. Tyner, Sean Conklin, Nicholas Olejnik, Robert L. Sprando
The utility of C. elegans as an alternative model to assess nanomaterial toxicity was evaluated using 10 nm silver particles (10nmAg). Endpoints of nanomaterial uptake and localization, larval growth, morphology, and DNA damage were assessed. Orally

A reference system for urinary albumin: current status

May 1, 2013
Author(s)
David M. Bunk, Karen W. Phinney, John C. Lieske, Olga Bondar, W. Greg Miller, Lorin M. Bachmann, Andrew S. Narva, Yoshihisa Itoh, Schimmel Heinz
Background: Increased urinary excretion of albumin reflects kidney damage and is a recognized risk factor for progression of renal and cardiovascular disease. Considerable inter-method differences have been reported for both albumin and creatinine

Automatically Detecting Faulty Regulation in HVAC Controls

May 1, 2013
Author(s)
Daniel A. Veronica
A new method is introduced to automatically detect faulty regulation of temperatures, pressures, and flow rates within the heating, ventilating, and air-conditioning (HVAC) systems and equipment of buildings by using digital data typically available from
