The use of halons for fire fighting is being phased out due to their deleterious effects on stratospheric ozone. This paper describes the findings of part of a study designed to characterize and identify super-effective thermal fire-fighting agents as

The oxidative potential (OP) of particles can be represented by the ability of particles to generate hydroxyl radicals in an aqueous solution which can be measured with electron paramagnetic resonance (EPR) spectrometry. The oxidative potential of

Minimum outdoor air ventilation rates specified in standards such as ASHRAE Standard 62.2 are generally based on envelope airtightness, building floor area, geographical location, and number of occupants. ASHRAE Standard 62.2 allows for a constant
The presentation will discuss the application of refrigerants starting from the beginnings of ‘artificial cold' in the era of industrial revolution to the currently used fluids, and the refrigerant options in response to concerns regarding stratospheric
Using Database-Assisted Design and the Tokyo Polytechnic University Aerodynamic Database, we show that face winds put more structural demand than corner winds do on the Citicorp Tower in Manhattan. This 59-story building, supported by four midside columns

The U.S. Consumer Product Safety Commission (CPSC) is focused on addressing the hazard of acute carbon monoxide (CO) poisoning of consumers from portable generators that can result in death or serious and/or lasting adverse health effects in exposed

Minimum outdoor air ventilation rates specified in standards such as ASHRAE Standard 62.2 are generally based on envelope airtightness, building floor area, geographical location, and number of occupants. To meet ventilation requirements in practice
Semi-volatile organic compounds (SVOCs) are ubiquitous indoors and associated with adverse health effects. y0 (the SVOC concentration in air close to the material surface) is the key parameter to predict SVOC emissions from source materials. However, to
A new Standard Reference Material (SRM) for portland cement clinker has been produced for the Office of Standard Reference Materials at the National Institute of Standards and Technology (NIST). The SRM clinkers are intended for use in developing and

TThis paper studies a selection of fine sands, their particle shape and its effect on the plastic properties of mortars via the influence on the workability and packing of cementitious mixtures. Five sands from different sources were sampled, wet sieved
Matlab Function VoronoiBound calculates a Voronoi diagram with inner and outer bounds. This function is useful in defining tributary areas of pressure taps regularly or irregularly placed on the outside surface of a wind tunnel model.
The CYCLE_D package simulates vapor compression refrigeration cycles that use pure refrigerants or blends of refrigerants. The model can simulate a basic subcritical or transcritical refrigeration cycle, both with or without a liquid-line/suction-line heat
