Journal of Aerosol Medicine and Pulmonary Drug Delivery, 2020
The distribution of particles sizes within an aerosol is essential information for understanding the behavior of that aerosol. The number of particles within certain size ranges is given by distributions specified by a count distribution if referring to number of particles, or a mass distribution if referring to particle mass. The cumulative number, or

Soil Science Society of America Journal, 2001
Conventional soil texture classification systems use different definitions of particle‐size distributions (PSDs). For example, sand in the International Soil Science Society (ISSS) system equals the combined separate limits of coarse silt and sand in the USDA system.

The objectives of this test are: 1. Measure the distribution of sizes of particles in a ceramic raw material from its largest size DL ≈ 6700 lim (6.7 mm) to its smallest size D, ≈ 0.010 \μm. Unfortunately there is no single apparatus which is capable of measuring this range of sizes, common in the classical ceramic industry. Consequently, it may

Particle sizes and particle size distributions are of both technical and scientific importance in emulsion polymerization systems On the technical side, particle sizes and particle size distributions are major determinants of a number of properties of a polymer latex, such as its viscoelastic behavior.

Particle Size Distributions and Particle Size Alterations in Microemulsions
Journal of Pharmaceutical Sciences, 1984Several component diagrams for different alcohols as cosurfactants and potassium oleate as the surfactant were investigated. Between the regions of the water-in-oil microemulsion and the micellar solution (reverse micelles), and diagrams showed a zone of instability which was determined by particle size analysis by means of photon correlation ...

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 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 ...

In this chapter, a state of the art of Particle Size Distribution (PSD) measurement of bio-based aggregates and characterization methods is presented. Shiv particles coming from the stem of plants cultivated either for their fibers (hemp, flax, etc.) or for their seeds (oleaginous flax, sunflower, etc.) are very different from the mineral aggregates ...

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.
