density

The formula determines the value of the density through the planets integral characteristics, that can be obtained on the basis of observation data.

Density and excess volume of the binary systems of iso-buthylmethacrylate with acetonitryle and benzene have been measured as a function of concentrations at 293 K and
atmospheric pressure by pycnometric method. The values of excessive and partial molar volumes of the components were calculated. The excess volume for the acetonitryle – isobuthylmethacrylate system receives negative values and for
the benzene system – isobuthylmethacrylate – positive values.

Purpose. The aim of the presented research was to analyze the problem of increasing the hydrocarbons resource base in Carpathian region by means of poorly explored deeply buried sediments of flysch formation in Folded Carpatians and Precarpatian foredeep. Relevance of conducted study concerning deep autochthonous sediments complex is caused by discovering Lopushna oil field in the underthrust of Pokuttya-Bukovyna Carpathians. Methodology. The research was performed by creating a spatial integral seismic-gravity model of northwestern part of Carpathian oil-and-gas bearing province.

The work is devoted to the development of alternative jet fuel blended with rapeseed oil-derived biocomponents and study of their physical-chemical properties. The modification of conventional jet fuel by rapeseed oil esters was chosen for this work among the variety of technologies for alternative jet fuels development. The main characteristics of conventional jet fuel and three kinds of biocomponents were determined and compared to the standards requirements to jet fuel of Jet A-1 grade.
