A method of estimating the form of fine particulates

, 2009
In the companion paper we noted that a significant body of literature exists to suggest that form can have an important influence on the behaviour of an assembly of particles during shear, and that at present there are no practical methods of measuring ...

Characterization of Ambient Air Particulates and Particulate Mercury at Sha-Lu, Central Taiwan

, 2009
Ambient air samples were collected between December 9, 2008, and January 14, 2009, at a highway traffic site located in Sha-Lu, central Taiwan. Atmospheric particulates and particulate bound mercury Hg(p) dry deposition, concentrations and dry deposition

Application of Plasma Surface Treatment to Solid-State Microscopic Particulates

, 2009
The plasma-assisted improvement of wettability and flowability of fine powders is described. The plasma down-stream reactor designed for an adequate treatment of particulates allows efficient surface modification and functionalization of particulates. It

Economic Development and Environmental Quality: An Econometric Analysis

, 1994
The relationship between economic development and environmental quality is analyzed econometrically for a large sample of countries over time. The results indicate that some indicators improve with rising incomes (like water and sanitation), others ...

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.
