The Response to Particulate Debris
Orthopedic Clinics of North America, 1993The 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.

The uptake of particulates by an urban woodland: Site description and particulate composition
Environmental Pollution, 1997Woodlands 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 ...

Study on Particulate Accumulated Characteristics of Diesel Particulate Filter
Applied Mechanics and Materials, 2012The paper has carried out numerical simulation and experimental study on the pressure loss of filter. Based on pressure loss model of filter, research methods of particulate accumulated characteristics has proposed according to the exhaust flow, exhaust temperature and exhaust back pressure.

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 ...

Particulate recording materials
Proceedings of the IEEE, 1986Information (audio, video, or data) to be recorded magnetically is first encoded into a sequence of time-varying electrical signals which are used to drive a writing head, the magnetic field of which creates, on the moving tape or disk, a spatially varying pattern of magnetization.

Particulate characterization by ultrasound
Pharmaceutical Science & Technology Today, 2000Ultrasound 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.

Bulletin de la Classe des sciences, 1960
The possible existence of undiscovered elementary particles is discussed. The electric charge Q and the « neutrinonic charge » R, introduced in a preceding paper (x), are given for two such particles, which are baryons : Q = 1, R = 0 and Q = -1, R = -2 ; for the newly discovered D-meson, they are Q = 1, R = 1.
