On the example of coal deposits of Transbaikalia, the main constituents of coals are characterized, the inherited and newly formed macerals are distinguished. The characteristic of the main carriers of microelements in coals is given: organic matter, mineral impurity, initial plant mass. A method for isolating paragenesis of trace elements from associations is proposed, which is of great importance in the evaluation of rare metals in fossil fuels. Specific examples of the isolation of paragenesis of microelements from associations in coals of various rare-metality are given. The statistical method of decomposition of gross contents of microelements on the basic carriers is substantiated. It is concluded that the infrared-organic concentrations of microelements played a decisive role in the formation of rare metal fossil fuels.

Partial molar volume, V0, of Ciprofloxacin in water, 0.05mol Kg-1 hydrochloric acid and 0.05 mol Kg-1, Iron (III) chloride solutions at 298.15 and 308.15 K was calculated fromprecision densities obtained fromDensity Sound Analyzer (DSA 5000). The data represent the smaller volume of drug in 0.05 mol Kg-1 Iron (III) chloride solution than water and 0.05 mol Kg-1 hydrochloric acid at constant temperature. The differences in volumes are interpreted as due to hydrophobicity of solutes. Relative hydrophobicities were estimated from volumes of transfer fromone media to another media. The hydrophobicity of this compound also plays a key role in the drug action. The possible mechanism of drug binding with the membrane structure is also discussed.
