Scavenging of Aerosol Particles by Precipitation
Journal of Applied Meteorology, 1980Abstract Airborne measurements have been made of aerosol particle size distributions (>0.01 μm) in aged air masses, in the plumes from several coal power plants and a large Kraft paper mill, and in the emissions from a volcano, before and after rain or snow showers.

The microwave properties of precipitation particles
Quarterly Journal of the Royal Meteorological Society, 1954AbstractThe theory of scattering and attenuation by rain, snow and cloud is reviewed and theoretical results are presented in the form of equations, tables and graphs, so that the radar response to meteorological particles can be calculated at six wavelengths (10, 5.7, 3.2, 1.8, 1.24 and 0.9 cm) and various temperatures.

Interference of Growing Spherical Precipitate Particles
Journal of Applied Physics, 1950The exact theory of the rate of growth of spherical precipitate particles has previously been developed for the initial stage where the individual precipitate particles do not interfere with one another. In the present paper this theory is carried one stage further to include their mutual interference.

Controlling particle size during anatase precipitation
AIChE Journal, 2001AbstractTitanium dioxide particles in the form of anatase are precipitated from concentrated titanyl sulfate solution in the sulfate process, which are then recovered by a filtration process downstream of the precipitation stage. A previous study by Sathyamoorthy et al.

Homogeneous Precipitation of Uniform Hydrotalcite Particles
Langmuir, 2002Hydrotalcite was synthesized by a homogeneous precipitation method utilizing urea hydrolysis. When the homogeneous aqueous solutions containing magnesium chloride, aluminum chloride, and urea were heated, hydrotalcite particles were obtained. Scanning electron micrographs revealed that the products were well-defined hydrotalcite particles. The particle

Auroral particle precipitation and Birkeland Currents
Reviews of Geophysics, 1974Correlated measurements that provide information on Birkeland (field aligned) currents are reviewed. Because of the obvious importance of field‐aligned electric fields with regard to Birkeland currents, the last section of the paper is devoted to a presentation of recent data on the observations of field‐aligned auroral electron fluxes and ...

Controlled Precipitation of Radiation Belt Particles
2003Abstract : The overall objectives of this work were to quantify the requirements for controlled precipitation of radiation belt particles in order to mitigate enhanced space particle effects, to address critical issues of antenna-plasma coupling, and to develop a model of the effective radiated power throughout the magnetosphere In carrying out this ...

Cloud and Precipitation Particle Size Spectra.
1982Abstract : Airborne measurements are described of the size distributions of cloud and precipitation particles in extratropical cyclones. Empirical expressions for the particle size distributions, and the effects of ambient conditions on these expressions, are described.

Precipitation strengthening in multi-particle systems
2014Kurzfassung Die vorliegende Dissertation beschreibt die Hauptaspekte eines physikalischen Modells f r Ausscheidungsh rtung in kristallinen Werkstoffen. F r die Evaluierung des Anstiegs der Streckgrenze wird ein System von Gleichungen abgeleitet, basierend auf der Interaktion zwischen Versetzungen und Ausscheidungen. Verschiedene Schermechanismen und
