The mapped chemostratigraphic units need not follow stratigraphic or lithostratigraphic units, as the chemical stratigraphy of an area may be independent of lithology.

Any geochemical criteria could be used to define chemostratigraphic units ; gold, nickel, carbonate, silica or aluminium content, or a ratio of one or more elements to another.

As a result, an audio component of improved characteristics may be obtained for relatively low cost.

The Panel believed strongly that the data available on this sighting was sufficient for positive identification if further data is obtained by photographing polyethylene " pillow " balloons released near the site under similar weather conditions, checking bird flight and reflection characteristics with competent ornithologists and calculating apparent " G " forces acting upon objects from their apparent tracks.

After the raw salt is obtained, it is refined to purify it and improve its storage and handling characteristics.

Such scores are generally obtained through the Montreal Battery of Evaluation of Amusia ( MBEA ), which involves a series of tests that evaluate the use of musical characteristics known to contribute to the memory and perception of conventional music.

When a user registers with the system which he / she will attempt to access later, one or more of his / her physiological characteristics are obtained and processed by a numerical algorithm.

Much new equipment and many unique techniques have been developed for the quantitative exposure of experimental animals to aerosols of infectious agents contained in particles of specified dimensional characteristics.

but the subsequent analysis of characteristics is reported only for the de jure population ( or, in some districts, only the de facto population ).

The high cost of land and a few operational problems resulting from excessive loadings have created the need for a wastewater treatment system with the operational characteristics of the oxidation pond but with the ability to treat more organic matter per unit volume.
