The initial thermal conductivity measurements from a guarded hot plate apparatus using multiple line-heat sources are presented for specimens of high-density molded fibrous-glass board. Measurements at ambient air pressures are in good agreement with
An approach for establishing metrological traceability for measurement results from guarded-hot-plate apparatus consistent with policy at the National Institute of Standards and Technology (NIST) is presented. A brief example for initiating met-rological
This paper presents liquid kinematic viscosity and density measurements of a synthetic polyolester-based aluminum oxide (Al2O3) nanoparticle dispersion (nanolubricant) at atmospheric pressure over the temperature range 288 K to 318 K. Two Al2O3 particles
An analytical model is formulated for the irradiance on a surface (collector) with a rear (opposite the sun) planar vertical diffuse reflector, as is common for a lower roof on a multi-story building. The vast majority of research on solar reflectors has
There is a lack of understanding of how structural systems perform under realistic, uncontrolled fires. Fire protection of steel structures is usually provided through prescriptive requirements. The development of performance-based standards and tools

Inverse atmospheric dispersion models are used to provide measurement-based, or topdown, estimates of greenhouse gas (GHG) emissions for comparison with input-based, or bottom-up, estimates. To minimize uncertainty, inverse estimates require accurate

The distillation behavior of mixed alcohols was studied using the Advanced Distillation Curve (ADC) methodology. Crude mixed oxygenates were generated from syngas over a potassium promoted cobalt molybdenum sulfide catalyst and assayed for major and minor

The synthesis of material information across lifecycle stages will lay the foundation for a material information model to support sustainable decision making. This paper explores how material information is represented in select standards that address
The National Institute of Standards and Technology (NIST) Measurement Science Roadmap for Net-Zero Energy Buildings Workshop Report (NIST TN 1660 March 2010) identified a number of broad challenges to achieving NZE high-performance green building

This paper assesses the impact of information technology use and Construction Industry Institute defined Best Practices on construction project performance. Using data from 133 projects collected in 2008 and 2009, correlations between Best Practice- use
Steel structures may be exposed to localized heating by ignition of the fire source nearby. Flame impingement from localized fire may lead to high temperatures in the exposed steel members, which may lead to structural collapse. This paper numerically

Several fire suppressants are under consideration to replace CF3Br for use in suppressing fires in aircraft cargo bays. In Federal Aviation Administration performance tests simulating the explosion of an aerosol can, however, the replacements HFC-125, 2-
Alkali-silica reaction (ASR) is a concrete degradation phenomenon in which the alkalis that are typically found in concrete react with certain amorphous or micro-crystalline siliceous phases in the aggregate and, in the presence of moisture, form an

Consolidating adhesives have been used throughout the centuries for the conservation of painted cultural objects- such as paintings and polychrome sculpture- and if it were not for these adhesives, many objects may not have survived to the present day
The authors have performed a useful service by providing a broad perspective on multi-hazard engineering. The discussers would like to complement that perspective by noting two results of practical significance in the context of design for multiple hazards
