The conditions for cresoxym-methyl determination by thin layer chromatography were studied. The maximum extraction of cresoxym-methyl was observed in chloroform at pH 6 - 8. The chloroform/toluene mixture (2/1, v/v) was best for the development of the thin layer chromatography plates. The method for cresoxym-methyl determination into sewage waters was developed in this study.

Vanadium-phosphate catalyst was synthesized and it was investigated the catalitic activity into metan oxidation reaction.

Specific features of tin telluride SnTe single crystals obtaining by reverse Bridgman technique are studied. The initial material was used to achieve crystallization without contact of the crystallization front with container walls. Based on the estimated thermodynamical characteristics of tin telluride an attempt is made to affect the stoichiometry of the substance being crystallized by formation of additional pressure of the volatile component in the free container volume. Some features of formation of temperature fields at crystallization are analyzed, melt flow dynamics at different stages of the process is simulated.

The measures of belonging are considered, i.e. quantitative characteristics of quantitative analysis (identification) of nuclide and element composition of substance using activation methods. Apparatus gamma spectra of irradiated sample are interpreted as a certain experimental text (ET), while an array of gamma-active nuclide lines possible for this sample - as a certain model word (MW). MW location in ET could be estimated by quantitative values - length, height, distance - that are the measures of belonging of this MW to ET. The use of the proposed measures of belonging for determination of Ba in samples of Muzhievo polymetal deposit.

This work is devoted to investigation of new view about inorganic origin of oil and natural gas on the Earth.

We made a monitoring of the concentration of Iron and Manganese compounds in surface and underground water of Berehiv region and concluded that because of the natural factors the concentration of these ingredients is much higher then the concentration - limit. That's why the water objects need to be purified before consuming them as a source of drinking water.
