[en] Results of testing the pallete for accounting the effect of anomalous values of mineralization of stratum water, carbon content and density of rock when determining porosity of clay deposits by neutron methods using the example of terrigenous rocks of Tuimasin oil deposits, are given. Application of the pallete permits to tave into account the effect of elevated density of mudded rocks when determining their porosity by neutron methods with practical accuracy

[en] Shown is the expedience and advantages of taking into account the measuring conditions in interpreting the neutron method data by correcting not the method indications, but the values of apparent porosity, determined according to non-corrected indications. Generalizing the existing experimental and theoretical data, the nomogram is plotted for accounting mineralization effect of stratal waters and drilling fluids based on correction of the apparent porosity value

[en] A procedure for the automated extraction photometric determination of phosphate ions in aqueous media was proposed based on the formation of colored phosphomolybdic heteropoly acid followed by its extraction from the aqueous phase to 1-butanol in the units of a hydraulic facility for cyclic-injection analysis. The procedure ensures a lower limit of the analytical range at a level of 80 μg/L at a sample volume of 10 mL

Предложена автоматизированная методика экстракционного фотометpического определения фосфат-ионов в водных средах, основанная на образовании окрашенной вoccтановленной молибдофосфорной гетерополикислоты с последующим ее экстракционным выделением из водной фазы в бутанол-1 непосредственно в узлах гидравлической схемы циклического инжекционного анализа. Методика обеспечивает нижнюю грaницу днапазона определяемых концентраций на уровне 80 мкг/л при объеме пробы 10 млJournal
[en] Mass spectrometry was used to show that 21-methoxy-19-methyl-3, 6, 9, 12, 15-pentaoxabicyclo [15.3.1] heneicose-1(21), 17, 19-triene and its 21-hydroxyanalogue in gaseous phase reacts with cations, containing Fe, Co, Ni, Cr, Mn, Rh, Nd, Pr, Ga, In and Tl atoms with formation of ions with a new metal-macrocycle bond. The characteristic feature of 21-hydroxyderivatie is formation of complexes with metal-oxygen (macrocycle) σ-bond. Reactivity of cation acetylacetonate complexes (acac)2M+ with respect to macrocyclic derivatives changes in M=Co > Fe > Cr > Pr, Ga series. The relative yield of metal-containing ions with a new metal-macrocycle bond is higher for methoxyderivative as compared to hydroxyanalogue
