One of the recommendations of the National Construction Safety Team for the Federal Building and Fire Safety Investigation of the World Trade Center Disaster (NIST NCSTAR 1, 2005) is to enhance the capability of available computational software to predict

In Situ Burning of Oil Spills: Resource Collection

February 19, 2017
Author(s)
William Walton
The Minerals Management Service (MMS), U.S. Department of Interior, is designated as the lead agency for in situ burn research in the Oil Pollution Research and Technology Plan prepared under the authority of Title VII of the Oil Pollution Act of 1990 (OPA

Influence of Particle Size on DCPD Hydrolysis and Setting Properties of TTCP/DCPD Cement

February 19, 2017
Author(s)
Limin Sun, Laurence C. Chow, Shozo Takagi, Elena F. Burguera, Stanislav Frukhtbeyn
This study investigated the effects of particle size on the hydrolysis reaction of DCPD at pH 7 and 37 C and on the setting properties of a TTCP/DCPD cement. The kinetics of the hydrolysis reaction was controlled by a nucleation and growth mechanism

Instability of Adhesion Force Between Rough Surfaces

February 19, 2017
Author(s)
Michael Nosonovsky, Seung H. Yang, Huan Zhang
Adhesion force has a significant effect upon the contact of rough surfaces with nanoscale asperities. The dominant component of the adhesion force is the capillary force caused by condensed water menisci. The capillary force depends upon the meniscus shape

Interfacial Dewetting in Silicon Nitride Containing Aligned Grains

February 19, 2017
Author(s)
B Hockey, D S. Park, H D. Kim, S W. Lee
It is generally believed that liquid phase sintering of silicon nitride invariably results in a continuous intergranular phase such that individual grains are separated by a glassy interphase, typically as thin as I nm. To the contrary, results presented

International Standards for Service Life Planning of Buildings

February 19, 2017
Author(s)
G J. Frohnsdorff, C Sjostrom, G Soronis
ISO Technical Committee TC 59, Building Construction, is an international standards committee dealing with general rules for performance requirements for buildings, SC 14, Design Life, is the subcommittee of TC 59 that deals with standardization of the

Investigation of Unresolved Issues From ATL Temperature Control Module

February 19, 2017
Author(s)
Stephen J. Treado
A series of measurements and performance evaluations has been conducted in the Temperature Control Module (TCM) for three control system vendors in order to demonstrate their ability to meet the high accuracy temperature control specification for the

Ionic Liquids as Compatibilizers for the Preparation of Biopolymer Nanocomposites: Characterization Using Laser Scanning Confocal Microscopy

February 19, 2017
Author(s)
Jeffrey W. Gilman, P H. Maupin, Mauro Zammarano, Paul C. Trulove, D M. Fox, H DeLong, Ph Dubois, M Murariu
The process of dispersing ionic liquid modified montmorillonite in polylactide (PLA) using a twin-screw micro-compounder under different melt-compounding parameters was monitored using laser scanning confocal microscopy (LSCM). In addition the PLA-MMT

Kinetic Modeling of Heptane Combustion and PAH Formation

February 19, 2017
Author(s)
Valeri I. Babushok, Wing Tsang
Kinetics of heptane combustion was studied through numerical modeling. High temperature kinetic model of heptane combustion was constructed. The model includes four main blocks of reactions: C1-C2 chemistry, which is based on Grimech-3.0 model; block of C3

Laser Stabilization

February 19, 2017
Author(s)
John L. Hall, Jun Ye, M S. Taubman
It becomes clear that there are many interlinking considerations involved in the design of-laser stabilization systems, and it is difficult to present a full description in an article such as this. Still it is hoped that the reader will see some avenues to

Lateral Force Microscope Calibration Using a Modified AFM Cantilever

February 19, 2017
Author(s)
Mark Reitsma
A proof-of-concept study is presented for a new force transducer and associated calibration method that provides a path for quantitative friction measurements using a Lateral Force Microscope. The transducer design is an Atomic Force Microscope (AFM)

Letter to the Editor of ACI Materials Journal

February 19, 2017
Author(s)
A M. Rosenberg
This letter contains a discussion of the article in the May-June 1999 issue of the ACI Materials Journal on the Investigation of Chloride Diffusion for High-Performance Concrete Containing Fly Ash, Microsilica and Chemical Admixtures, by Zongjin Li, Jun

Lifetime Prediction for Silicon Nitride

February 19, 2017
Author(s)
Sheldon M. Wiederhorn
This paper reviews lifetime prediction methodologies for high-temperature structural ceramics. The methodologies consider failure from subcritical crack growth at low temperatures, 800 C to 1000 C, and creep, or creep-rupture at high temperatures. The

Localized Ignition and Subsequent Flame Spread Over Solid Fuels in Microgravity

February 19, 2017
Author(s)
Takashi Kashiwagi, Y N. Nakamura, Kuldeep Prasad, Howard R. Baum, S L. Olson, O -. Fujita, K K. Nishizawa, K. Ito
Ignition and subsequent flame spread over a paper sample and a PMMA sheet in microgravity are studied experimentally and theoretically. New results obtained during last two years are described.

Material Properties of a Sintered a-SiC

February 19, 2017
Author(s)
R G. Munro
A self-consistent, single-valued representation of the major physical, mechanical, and thermal properties of a sintered Α-SiC is presented. This comprehensive set of properties is achieved by focusing on a narrowly defined material specification in which
