Contribution of Particulates to Airborne Disease Transmission and Severity: A Review.

Environmental Science and Technology
The emergence of coronavirus disease 2019 (COVID-19) has catalyzed great interest in the spread of airborne pathogens. Airborne infectious diseases are classified into viral, bacterial, and fungal infections.

Numerical modelling of supersonic boundary-layer receptivity to solid particulates

Journal of Fluid Mechanics, 2018
Atmospheric particulates may be a major source of boundary-layer instabilities leading to laminar–turbulent transition on aerodynamically smooth bodies flying at supersonic speeds.

Measuring Particulate Load in a Diesel Particulate Filter

SAE Technical Paper Series, 2006
<div class="htmlview paragraph">A gravimetric particulate measurement system, which extracts samples isokinetically from raw exhaust, is presented to quantify the particulate mass stored in diesel particulate filters. The purpose of this measurement system is to facilitate the study of wall-flow filter behavior at different particulate load ...

Airborne Particulates in the OR Environment

AORN Journal, 1999
ABSTRACTIntraoperative sampling of airborne particulates is rarely performed in teh OR environment because of technical difficulties associated with sampling methodologies and because of the common belief that airborne contamination is infrequently associated with surgical site infections (SSIs).

Optical properties of particulates

Astrophysics and Space Science, 1975
Optical properties of small particles of olivine (less than 0.1 μ) have been studied in the ultraviolet as an example of an insulating solid. Very little structure survives in the ultraviolet extinction curves for such small particles. By contrast ‘surface modes’, observed for graphite small particles in the ultraviolet and for olivine particles in the

Wear particulate and osteolysis

Orthopedic Clinics of North America, 2005
Total joint replacements of the hip and knee are generally highly successful, with satisfactory longevity and clinical results. Using modern biocompatible materials, optimal component design, and meticulous surgical technique, survivorship of cemented or cementless joint replacements is approximately 15 years with more than a 90% probability.
