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.

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).

The Response to Particulate Debris

Orthopedic Clinics of North America, 1993
The most common cause of failure of total hip and other arthroplasties is aseptic loosening of the prosthesis. Substantial evidence suggests that the adverse tissue response to prosthesis wear particles is an important contributor to bone loss around implants.

Particulate Activity in Urine

British Journal of Urology, 1983
Summary— A new method of measuring urinary particulate activity is described. The analytical process, using a Coulter Counter, is designed to have minimal effect on the dynamic nature of the specimen. Emphasis is placed on conducting the analysis during the first 5 min following voiding, preventing changes in ...

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 ...

Particulate characterization by ultrasound

Pharmaceutical Science & Technology Today, 2000
Ultrasound is a technique that is capable of tremendous accuracy and precision, whether in the laboratory or on-line in the factory. Data acquisition rates of the order of kHz transform process monitoring, providing unprecedented information of high statistical value.

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

The uptake of particulates by an urban woodland: Site description and particulate composition

Environmental Pollution, 1997
Woodlands may improve local air quality by increasing the uptake rates of gaseous, particulate and aerosol pollutants from the atmosphere and can also act as relatively permanent sinks for some pollutants. Rough Wood, Walsall was selected for a study of the material which accumulates on tree foliage because of its location in a densely populated urban ...
