АНАЛІЗ КОНТРАСТНОСТІ МЕЗОСТРУКТУР ҐРУНТОВОГО ПОКРИВУ АГРОЛАНДШАФТІВ ПАСМОВОГО ПОБУЖЖЯ

Under the influence of anthropogenic stress, soil cover undergoes significant transformations, which become apparent in its structure changes. The analysis of the mesostructured contrast of the soil agrarian landscape will allow us to duly detect the areas of agrogenic heterogeneity intensification and introduce measures to prevent soil mantle deterioration, which today is a necessary condition for the sustainable use of soils. The object of research is soil mesocombinations of the Pasmove Pobuzhzhia agro landscapes – the region of intensive agricultural use. The study was conducted in an attempt to establish the reasons for the contrast formation of the soil cover mesocombinations, determine the partial coefficients and the integral contrast index, and group the soil combinations according to these indicators. Comparative geographical, field-map metric, and calculation methods were used for the research. A soil map on a scale of 1:10,000 was taken as the cartographic base for the research. The soil cover of Pasmove Pobuzhzhia is formed by automorphic (grey forest, dark grey podzols, sod-carbonate), semi-hydromorphic (meadow), and hydromorphic (swampy, swampy-meadow, peatland) soils. In the structure of the soil landscape under study, the variations, combinations, soil associations, and mosaics are highlighted. The main factors determining the formation of the soil mantle contrast of mesocombinations are the genetic heterogeneity of the soils, the different granulometric composition and the level of denuded soil. The division of soil combinations into groups according to the degree of contrast and the number of factors determining it is proposed. It has been established that the soil variations are characterized by a minimum integral contrast index (45.25-49.6 %). This type of soil combinations contrast is formed almost exclusively due to the development of erosion processes and the formation of denuded to different extent soils (single-factor contrast). The combinations and soil associations contrast is much higher than that of variations. Soil combinations, it is formed under the influence of erosion processes and the genetic heterogeneity of soils. It has been stated that as for the combinations, the partial coefficients of genetic contrast fluctuate within wider limits (7.9¬29.2 %) than the coefficients according to the degree of soil erosion (53.6-66.1 %). For soil associations, contrast is formed due to genetic heterogeneity and granulometric composition. According to the number of factors, it is proposed to consider the contrast of combinations and soil associations as two-factor. Even though mosaics are classified as medium-contrast combinations, the value of the integral contrast index approaches the range of high-contrast combinations. Their contrast is multifactorial, i.e. caused by all the listed factors. Regarding the findings of the study, it has been stated that water erosion processes are the main factor in the soil cover contrast formation in the agro-landscapes of Pasmove Pobuzhzhia. The temporal dynamics analysis of the soil cover contrast indicators will allow us not only to identify the areas of the most important implementation of soil protection measures but also to evaluate their effectiveness.

Correct definition of internal energy at the phenomenological construction of model of multicomponent continuous medium by methods of nonequilibrium thermodynamics

Taking into account the methods of thermodynamics of irreversible processes using the Onsager principle, a model of a multicomponent continuous medium is constructed, the internal energy of which is "free" of the kinetic energy of diffusion. The model is designed for an imperfect continuous medium with chemical reactions in the field of conservative external forces. Generalized StefanMaxwell relations are obtained, which represent a system of hydrodynamic equations of motion of a mixture with true inertial forces. The proposed thermodynamic technique made it possible to obtain a number of algebraic relations known from the kinetic theory of gases for the transfer coefficients, relating, in particular, the coefficients of multicomponent diffusion with binary diffusivitys, thermal diffusion ratios with thermal diffusion coefficients and multicomponent diffusion coefficients, true (molecular) thermal conductivity coefficient for multicomponent mixture with partial thermal conductivity coefficient, which indicates their versatility. The results obtained are intended for modeling not only liquid imperfect solutions, but also gas-dust mixtures with a finely dispersed dust component.

Экспериментальное определение удельного коэффициента образования диоксида азота при горении нитроцеллюлозной киноплёнки

Purpose. Pulmonotoxic substances (for example, nitrogen dioxide) are extremely hazardous for people during fires. These substances cause mucous membrane irritation and with prolonged exposure can lead to toxic pulmonary edema. However, fire load database which is used for calculating fire risks does not contain values of nitrogen dioxide formation distribution coefficient. Therefore, determining parameters of nitrogen dioxide formation during various substances and materials burning is a priority. The purpose of the study is to experimentally determine the partial density and distribution coefficient of nitrogen dioxide formation during cellulose nitrate film combustion in an enclosed volume. To achieve it an experimental installation for determining fire hazard of condensed materials during their thermal decomposition has been modified. Methods. Experimental methods of measuring and processing parameters of substances and raw materials burning as well as obtained results analysis methods are used. Findings. A technique for experimental calculation of nitrogen dioxide formation distribution coefficient has been developed and validity of obtained results approximation for real rooms has been justified. Values of distribution coefficient of forming nitrogen dioxide evolved during cellulose nitrate film combustion are experimentally obtained. Maximum weight of the above-mentioned film located in a room of a given volume at which NO2 partial density does not reach its critical or fatal value for people has been assessed. Research application field. Fire load database used when calculating fire risks, according to distribution coefficients of nitrogen dioxide formation during various substances andmaterials combustion has been expanded. Conclusions. The modified experimental installation for determining fire hazard of condensed materials during their thermal decomposition, as well as the developed method for experimental determination of nitrogen dioxide formation distribution coefficient make it possible to obtain data on nitrogen dioxide formation necessary for calculating fire risks in buildings and structures.

Dissociative Recombination in the Afterglow of Low-pressure Barrier Discharge. Population of Ne(2p-=SUP=-5-=/SUP=-3d) Atoms

The decaying neon plasma produced by the dielectric barrier discharge (DBD) in a cylindrical tube at a pressure of 0.1-40 Torr has been spectroscopically investigated to analyze the dissociative recombination (DR) of molecular ions with electrons as a mechanism for the formation of excited atoms. It is shown that, at the electron density in the afterglow less than 5·1010 cm-3 the DR is the dominant source of population of 3d levels at pressures PNe≥ 0.6 Torr. At lower pressures, the optical properties of the decaying plasma are formed to a greater extent by the collisional-radiative recombination of Ne+ ions. A significant variation of the relative intensities of the 3d->3p transition lines in the afterglow with a change in gas pressure was found, reflecting the effect of inelastic collisions on the formation of the spectrum of decaying plasma in the near infrared region. From measurements carried out at a pressure of 0.6 Torr, the relative values of the partial DR coefficients for the 3dj levels of the neon atom were found. Comparison of these data with measurements in the near ultraviolet region, containing the lines of 4p->3s transitions, indicates the need to take into account the cascade 4p->3d transitions to correctly solve the problem of the final products of dissociative recombination. Keywords: dielectric-barrier discharge, low-pressure plasma, optical emission spectroscopy, dissociative recombination, molecular ions, collisional-radiative recombination, cascade transitions.

It can prove that when the signal length is <inline-formula><tex-math notation="LaTeX">$N$</tex-math></inline-formula>, then at least <inline-formula><tex-math notation="LaTeX">$\tau (N)$</tex-math></inline-formula> DFT coefficients must be sampled, where <inline-formula><tex-math notation="LaTeX">$\tau (N)$</tex-math></inline-formula> is the number of factors of the signal length <inline-formula><tex-math notation="LaTeX">$N$</tex-math></inline-formula>. A recovery algorithm is proposed and implemented. It can achieve the lowed bound for length <inline-formula><tex-math notation="LaTeX">$N=2^{m}, m \leq 6$</tex-math></inline-formula>. To overcome the length limitation problem, a more practical recovery method is also proposed and implemented for <inline-formula><tex-math notation="LaTeX">$N=2^{m}, m&gt;6$</tex-math></inline-formula>. We can sample 11&#x0025; of the total DFT coefficients to perfectly recover the binary signal. We also extend the concept of ambiguity pair to other discrete transforms (DCT and WHT) and two-dimensional DFT cases.

A study on radiation shielding potentials of green and red clayey soils in Turkey reinforced with marble dust and waste tire

The increasing radiation applications in our daily life makes it essential to protect ourselves from the harms of radiation by using alternative, cheap and natural materials. The present study aimed to analyze the radiation shielding abilities of green and red clayey soils from Oltu/Erzurum in Turkey, reinforced with waste tires and marble dust. For the purpose to investigate the shielding features of the samples, radiation attenuation parameters were determined by using EpiXS software, which can calculate partial or total cross-sections, partial or total mass attenuation coefficients, electron densities, effective atomic numbers, and buildup factors for energy absorption and exposure between 1keV and 1GeV. We compared the obtained mass attenuation coefficients and total atomic cross-section values of the samples with those of a widely used shielding material, ordinary concrete, to make a meaningful evaluation about the shielding potentials of the samples. To validate obtained values by EpiXS, we also calculated the mass attenuation coefficients of the samples by XCOM code, and compatible results were obtained. Among all the studied clayey soil samples, green clay reinforced with marble dust and waste tire has the highest shielding capability. It can also be mentioned that reinforcement with marble dust and waste tire improves the shielding ability of the clayey soils.

Comparative analysis of oil ageing intensity in 110 kV transformers and 330 kV autotransformers

The results of transformer oil ageing intensity analysis in 110 kV transformers and 330 kV autotransformers are presented. Using a mathematical model of variance linear regression analysis (covariance analysis model), applied to the results of periodic tests on 231 transformers of 110 kV and 49 autotransformers of 330 kV, several statistical hypotheses have been tested to estimate the intensity of drift of oil indicators during long-term operation of transformers. The following hypotheses were tested as statistical hypotheses: the hypothesis of a significant systematic drift in the values of oils during long-term operation, which allows assessing the presence of transformer oil ageing processes. The hypothesis of equality of partial angular coefficients for regression models based on test results for each of the oil in individual transformers (regression lines are parallel), which allows estimating the differences in the ageing intensity of oils in individual transformers. The hypothesis that the group averages lie on a straight line, that is, the drift of the oil in the different transformers occurs at the same rate. The hypothesis of equality of partial free terms for regression models based on test results for each of the oil indicators in individual transformers, which allows assessing the presence of differences in the values of oil indicators at the time of commissioning of transformers, that is, the actual presence of differences in the quality of the poured oil. The results of the analysis for both 110 kV transformers and 330 kV autotransformers showed not only an additive and multiplicative bias between individual series of oil parameters, but also a significant systematic component, indicating the aging of transformer oils in the analysed transformers. It was found that the intensity of drift of oil indicators in 110 kV transformers and in 330 kV autotransformers significantly differs, which should be taken into account when building models for the early recognition of the condition of transformer oils by the results of periodic tests.

Design strengths of bamboo based on reliability analysis

To reasonably determine the design strengths of bamboo, in this work, the tensile strength parallel to particles, compressive strength parallel to particles, tensile strength perpendicular to particles, and compressive strength perpendicular to particles of bamboo were systematically investigated. The tensile strength parallel to the grain of the bamboo material was the highest, and it reached the minimum when perpendicular to the grain. The influence of the functional form of the probability distribution and data points for fitting on the reliability was evaluated by the first and second-moment checking point method. It was recommended to use the fitting results of the first 15% strength data and the 2-P-Weibull probability distribution model to determine the design values of the bamboo strength. On the basis of reliability analysis, the variation rule of reliability index and resistance coefficient of bamboo under different load combination types and load-effect ratios was calculated. The optimum partial resistance coefficient of the bamboo was determined by minimising the sum of squares of error, and the design strength of the bamboo was determined accordingly.

Effect of Al2O3 on the molten slag microstructure information by molecular dynamics simulation and experimental analysis

The metallurgical properties of blast furnace slag changed when high alumina iron ore was used extensively due to the resulting changes of the molten slag microstructure. In the study, based on typical CaO–MgO–SiO2–Al2O3 slag systems with different w(Al2O3) content, molecular dynamics simulation was used to calculate the microstructural properties of particles in the high-temperature slag system, such as bond length, partial radial distribution function, coordination numbers, and diffusion coefficient. In addition, X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, and 27Al solid-state magic angle spinning nuclear magnetic resonance (27Al SS MAS NMR) were used to detect and analyze the samples. The comprehensive calculations and experimental results show that increasing w(Al2O3) can enhance the structural stability of each ion pair, and the strength of the structural stability is such that Si–O > Al–O > Mg–O > Ca–O. The self-diffusion coefficients are as follows: Mg2+ > Ca2+ > Al3+ > Si4+, which leads to the transformation of the [SiO4]4−(Q0), [Si2O7]6−(Q1) and [Si2O6]4−(Q2) structural units to [Si2O5]2−(Q3). The degree of polymerization of slag increased as well as the stability of the structural units. Moreover, the coordination of Al will change from the [AlO6]9−octahedral structure of six-coordinated Al to the [AlO5]7−pentahedral structure of five-coordinated Al and the [AlO4]5−tetrahedral structure of four-coordinated Al. It was also found that the content of non-bridge oxygen in the whole slag system decreased continuously, leading to the increasing degree of polymerization of slag, and the experimental results were consistent with the molecular dynamics calculation.

Hesitant Fuzzy 2-Dimension Linguistic Programming Technique for Multidimensional Analysis of Preference for Multicriteria Group Decision Making

The hesitant fuzzy 2-dimension linguistic element (HF2DLE) allows decision makers to express the importance or reliability of each term included in a hesitant fuzzy linguistic element as a linguistic term. This paper investigates a programming technique for multidimensional analysis of preference for hesitant fuzzy 2-dimension linguistic multicriteria group decision making. Considering the flexibility of HF2DLEs in expressing hesitant qualitative preference information, we first adopt HF2DLEs to depict both the evaluation values of alternatives and the truth degrees of alternative comparisons. To calculate the relative closeness degrees (RCDs) of alternatives, the Euclidean distances between HF2DLEs are defined. Based on RCDs and preference relations on alternatives, the group consistency and inconsistency indices are constructed, and a bi-objective hesitant fuzzy 2-dimension linguistic programming model is established to derive the criteria weights and positive and negative ideal solutions. Since the objective functions and partial constraint coefficients of the established model are HF2DLEs, an effective solution is developed, through which the RCDs can be calculated to obtain the individual rankings of alternatives. Furthermore, a single-objective assignment model is constructed to determine the best alternative. Finally, a case study is conducted to illustrate the feasibility of the proposed method, and its effectiveness is demonstrated by comparison analyses.
