GIANT RAMAN SCATTERING OF ORGANIC LUMINOPHORS ADSORBED ON QUARTZ SURFACE MODIFIED BY SILVER NANOPARTICLES

Posted in 2019, Issue № 10(88) October 2019, PHYSICS AND MATHEMATICS | 0 comments

This work shows the results of studies on the development of a methodology for creating hydrosol-modified silver nanoparticles with a size of 44 nm quartz surfaces for sensory purposes. A method for the controlled synthesis of silver hydrosols by means of reducing sodium salt AgNO3 with sodium citrate is proposed. Media are proposed that enable the realization of the effect of giant Raman scattering by dye molecules of rhodamine 6G. It was shown that the order of amplification of the Raman signal by surface plasmons of silver nanoparticles for rhodamine 6G dye molecules can reach orders of magnitude 102 times. The efficiency of the practical use of hydrosols of silver nanoparticles of quartz surfaces to obtain the allowed spectra of the molecular structure of the rhodamine 6G dye is shown. In the future, the results of this work can be used to analyze chemical compounds in low concentrations and macroscopic biological objects.

INFLUENCE OF 1-HYDROXY-1.1-ETHYLIDE DIPHOSPHONIC ACID ON THE BEHAVIOR OF RAT FEMALES IN “OPEN FIELD” AND “ELIMINATED PLUS MAZE” TESTS

Posted in 2019, BIOLOGY, Issue № 10(88) October 2019, БИОЛОГИЧЕСКИЕ НАУКИ | 0 comments

The article presents data on the study of the effect of 1-hydroxy-1.1-ethylidene diphosphonic acid in a wide range of doses (from 5 to 200 mg/kg) on the behavior of female rats in the open field and elevated plus maze tests. The experiments were performed on 60 female Wistar rats. The results show that studied acid in the open field test at a dose of 150 mg/kg inhibits the locomotor activity, search and research behavior of the test animals, which indicates a sedative and anxiogenic effect of this dose of acid. These effects were reflected in a significant decrease relative to the control of the total distance by 49.06% (p≤0.001, n = 10) and the research activity of minks by 51.85% (p≤0.05, n=10). The “elevated plus maze” test showed a weak anxiogenic effect of 1-hydroxy-1.1-ethylidene diphosphonic acid at a dose of 150 mg/kg, which manifested itself only in a significant decrease relative to the control of the exit time of rats to the centre of the labyrinth by 79.35% (p≤0.05, n=10).

INDICATORS OF CARDIORESPIRATORY SYSTEM OF RATS UNDER THE EFFECT OF BIS (2-PYRIDYL) -3- (1,2,4-TRIAZOLYL) PROPANE

Posted in 2019, BIOLOGY, Issue № 10(88) October 2019, БИОЛОГИЧЕСКИЕ НАУКИ | 0 comments

The article presents the results of the study of the effect of bis (2-pyridyl-1,2,4-triazolyl-3) propane in doses of 5, 50, 100, 150, and 200 mg/ kg on the cardiorespiratory system of male and female rats. The experiments were performed on 84 Wistar rats (42 males and 42 females). It was shown that bis (2-pyridyl-1,2,4-triazolyl-3) propane (BTP) at a dose of 50 mg/kg has the most pronounced effect on the regulation of microcirculation, which was manifested in the increase of the activity of all factors regulating microcirculation. At this dose, it exhibits a hypotensive, vaso-relaxing and negative chronotropic effect. At a dose of 100 mg/kg, BTP exhibits hypertensive, vaso-constrictive, and positive chronotropic effects. It is likely that the presence of 1,2,4-triazolyl in the BTP molecule is crucial for the emergence of cardio and vaso-tropic properties.

DEPENDENCE OF STANDARD OF FINENESS OF FREE GOLD OF HYDROTHERMAL DEPOSITS ON COMPOSITION OF HOST ROCKS

Posted in 2019, GEOLOGY AND MINERALOGY, Issue № 10(88) October 2019 | 0 comments

It is generally believed that the standard of fineness of gold of hydrothermal deposits is determined by the types of sources of the initial fluids, the ratios of Au and Ag in them, P, T and the depths of deposits formation as well as the composition of the host mineral paragenesis. This study shows the decisive role of an additional factor and namely the alkalinity of ore-bearing rocks. In the process of presternal and synergistic metasomatosis, they can additionally enrich deep Na or K fluids, which, in turn, can significantly change the solubility of Au and Ag in them. Using the example of three gold ore deposits, the following relationship is established. Terrigenous rocks of Na-K specialization of the Tokur deposit (Russia) have slightly changed the Na/K ratio in the initial potassium fluids; as a result, intermediate and low-grade gold was deposited in ores (811–691 %). The fluids of the Odolgo (Russia) and Kalgoorlie (Australia) deposits, which were formed in the Na specialization rocks, were significantly enriched in sodium during metasomatosis. The standard of fineness of gold deposited in the ores of these deposits is above 900 %

OCIO-ECONOMIC FACTORS OF TECHNOSPHERIC FIRES: EXPERIENCE OF STATISTICAL ANALYSIS

Posted in 2019, GEOLOGY AND MINERALOGY, Issue № 10(88) October 2019 | 0 comments

Technospheric fires are considered as one of the risks to the sustainable development of the Russian regions. Spatial differentiation of their frequency is associated with a number of socio-economic characteristics of the areas that directly or indirectly describe the susceptibility of their infrastructure to fires and the degree of risk-taking behavior among the population. Numerical analysis for the period of 2007-2016 was performed. For the country as a whole, the overall crime rate, per capita sales of vodka, specific number of disabled people, and people living in nursing homes, the level of per capita income relative to the subsistence minimum were significant characteristics. In the groups of regions ranked by the deviation from the average population, the significance of these indicators is not the same. In certain ranking groups, socio-economic indicators that did not describe the country as a whole turned out to be significant: share of dilapidated housing and housing equipped with central heating, share of people registered as alcoholics, the level of actual final consumption and unemployment.

INFLUENCE OF HYDRO AND LITHO-DYNAMIC FLOWS ON THE CHARACTER OF MODERN EROSION DIVISION OF TERRITORIES

Posted in 2019, Issue № 10(88) October 2019, SCIENCES ABOUT THE EARTH | 0 comments

The article considers the problem of identifying the areas of increased denudation on the earth’s surface. Uplifting areas of the same rank are associated with them. The signs of distinguishing denudation areas, features of their structure and the nature of their division are presented. The boundaries of such regions are zones of stress release, potential discontinuities of terrestrial matter of different ranks, where systems of relatively independent (parallel with a shake of 45°) hydro- and lithodynamic flows function. The boundaries of denudation areas of three ranks are shown within the territories of the Volga-Ural and Caspian oil and gas provinces. Obtained information on the areas of denudation can be used for identifying potentially dangerous places where the restructuring of hydro- and lithodynamic flows of different ranks and the intensification of erosion processes are possible.

LANDSCAPE OF THE MONGOL-SIBERIAN REGION AS A RESULT OF INTERACTION OF EXTERNAL AND INTERNAL EARTH PROCESSES

Posted in 2019, Issue № 10(88) October 2019, SCIENCES ABOUT THE EARTH | 0 comments

The morphostructural features of the Mongol-Siberian region are of great interest when it comes to the study of the dynamics of neo-tectonic development, a significant contribution to which is made by modern vertical and horizontal movements. In this work, the geo-information analysis of a digital elevation model is carried out, and areas of sedimentation and denudation are highlighted. The spatial configuration of the selected regions is the result of the complex interaction of the Earth’s hard shell and its atmosphere. The mass volume generated in the areas of drift and accumulation characterizes the complex structure of the exogenously active layer, which is affected by a complex of exogenous processes. The results of the surface analysis allow, to a first approximation, estimating the ratio of the thickness of the lithosphere and asthenosphere in areas with different conditions of sedimentogenesis.

INFLUENCE OF LANTHANUM OXIDE ON THE PROPERTIES OF CHEMICALLY RESISTANT CERAMICS OBTAINED WITH THE USE OF GALVANIC SLUDGE

Posted in 2019, ENGINEERING, Issue № 10(88) October 2019 | 0 comments

This paper presents the results of an experimental study of the dependence of the operational properties of ceramics on the amount of lanthanum oxide in the composition of charge. The main component of the processed charge is low-plastic clay, the use of which does not allow obtaining high-quality products. Additional additives are boric acid and galvanic sludge, which allow lowering the temperature of liquid-phase sintering to obtain a chemically and thermally stable glassy phase. In the course of the studies, it was found that lanthanum oxide is involved in the formation of the glassy phase leading to an increase in its strength, chemical and thermal resistance. The amount of lanthanum oxide was determined by the results of the work, which enables effective improvement of the quality of the obtained chemically resistant ceramics.
