Particle Size Distributions from Multiparticulate Dissolution
Drug Development and Industrial Pharmacy, 1998It has been demonstrated theoretically that the particle size distribution of particles in a given sieve fraction of a powder may be assessed by means of short-term dissolution data. Theoretical considerations in this article show that by accounting for polydispersity in a powder sample, the cubic expression in time for amount undissolved and fraction ...

Technegas and Pertechnegas particle size distribution
European Journal of Nuclear Medicine, 1995Technegas and Pertechnegas are radioactive aerosols produced in a commercial generator and used for lung scintigraphy. The aerosols are produced by first evaporating to dryness standard technetium-99m generator eluate (99mTcO4 in normal saline) in a graphite crucible (the simmer stage) and then heating this to 2500 degrees C (the "burn" stage). The aim

Particle Size and Distribution
2018Particle size distribution, the measure of subdivision of a solid, can be directly correlated with uniformity of quality and performance. Primary particle size is a physicochemical property that may impact temporal chemical and physical effects such as stability and aggregation.

Particle Size Distribution of Settled Dust
Journal of the Air Pollution Control Association, 1965In 1958, San Bernardino County Air Pollution Control District adopted rules and regulations for the control of dust, fumes and particulate matter. These were taken from ordinances which had been effectively used in other areas. After three years, experience showed that in some instances these rules and regulations should be modified to take into ...

Comparison of the Particle Size Distribution
ATZautotechnology, 2003Tests were carried out in order to determine the particle size distributions of several bus engines in the steady-state 13-mode test (ESC). The stoichiometric gas engines met the emission targets for EEVs and the expected Euro 5 standards for 2008.

Particle Size and Size Distribution
2015Abstract Particle size and size distribution have a significant effect on the behavior of metal powders during their processing. This article provides an overview of the sample preparation process for particle size measurement, which is a key step in the measurement of particle size distributions.

Estimating Functionals of Particle Size Distributions
Biometrika, 1971SUMMARY Data consisting of the intersections of a planar or linear probe with a field of spheres, with a diameter distribution G(x), is often used to estimate linear functionals or their ratios. It is shown that distribution-free estimators may be poor and that their distribution, even in large samples, depends on knowledge of G for small x that may be

Particle Size, Size Distributions and Shape
2009Only for spheres, the size of a particle can be represented by a single parameter, being e.g., its diameter. For the description of a particle of any other shape more parameters are required. Many different descriptors exist. They can be directly related to visual or microscopic measurement, such as length or breadth, or they are based on the concept ...

Characterizing Particle Size and Size Distribution
2012CHARACTERIZING THE SHAPE, SIZE AND SIZE-distribution of particles that go into liquid paint or coating formulations as well as dry formulated powdered coatings are very important. These materials may vary from being ground mineral fillers to crystalline epoxy cross-linkers and catalysists used in finished powdered paint products. There is a significant
