The Chemistry of Precipitation in Relation to Precipitation Type
Science of The Total Environment, 1982Abstract Collections have been made of several types of wet deposition and of aerosols in various particle size ranges. The chemical composition of the precipitation changes significantly from one precipitation type to another. The forms of deposition, diffusionally-grown ice for example, compared with accretionally-grown ice, appear to be important ...

A MODEL WITH A PRECIPITOUS IDEAL, BUT NO NORMAL PRECIPITOUS IDEAL
Journal of Mathematical Logic, 2013Starting with a measurable cardinal κ of the Mitchell order κ++ we construct a model with a precipitous ideal on ℵ1 but without normal precipitous ideals. This answers a question by T. Jech and K. Prikry. In the constructed model there are no Q-point precipitous filters on ℵ1, i. e. those isomorphic to extensions of Cubℵ1.

From 1995 to 1998 the concentrations of 4-nitrophenol, 2-methyl-4-nitrophenol, 3-methyl-4-nitrophenol, dinitro-ortho-cresol (DNOC) and 2,4-di-nitrophenol were measured monthly by HPLC in precipitation at eight different locations in Bavaria (Germany).

Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2016
Abstract The objective of this work was to investigate the effect of precipitating environment on asphaltene precipitation such as, precipitant (n-alkanes: C5, C7, C9, C12, C14), asphaltene concentration, and temperature. A combination of gravimetric and spectroscopic techniques was used for the detection and quantification of asphaltene ...

Precipitable water and precipitation in Athens
Archiv für Meteorologie, Geophysik und Bioklimatologie Serie B, 1977Total precipitable water, its variation with height, and its climatological relationship with precipitation are examined for the Athens area (Hellinikon Airport, 37°54'N, 23°44'E, 15 m a.s.l.) and for the period 1968–1974.

Precipitation Days and Precipitation Variability
1958Contained within the 3rd Edition (1957) of the Atlas of Canada is a plate with three maps that show the mean annual number of days with measurable precipitation, the mean annual number of days with measurable snowfall, and the variability of annual precipitation.

Trichloroacetic acid (TCA) precipitation of proteins is commonly used to concentrate protein samples or remove contaminants, including salts and detergents, prior to downstream applications such as SDS-PAGE or 2D-gels. TCA precipitation denatures the protein, so it should not be used if the protein must remain in its folded state (e.g., if you want to ...

Particle precipitation efficiency in an electrostatic precipitator
Journal of Electrostatics, 2005Abstract In this paper, results of the measurements of the size distribution of seed particles after their precipitation in a wire-plate-type ESP with seven wire electrodes are presented. The cigarette smoke was used as a source of seed particles. The particles of sizes from 0.5 to 8 μm were counted in the 0.5 μm-wide ranges at the ESP outlet using a
