The algebraic hyperstructure of elementary particles in physical theory

Algebraic hyperstructures represent a natural extension of classical algebraic structures. In a classical algebraic structure, the composition of two elements is an element, while in an algebraic hyperstructure, the composition of two elements is a set. Algebraic hyperstructure theory has a multiplicity of applications to other disciplines. The main purpose of this paper is to provide examples of hyperstructures associated with elementary particles in physical theory.Comment: 13 page

Images of Food and Drinks as Part of Mythopoetic Image of City in Vladivostok Text (by Example of Novel by I. Lagutenko, V. Avchenko “Vladivostok-3000”)

The article is devoted to the analysis of “food and drinks” symbols used by the authors of urban literary texts in reconstruction of the mythopoetic image of Vladivostok. The novel “Vladivostok-3000” is investigated. The authors consider it as one of the works about Vladivostok, for which the concept of “Vladivostok text” is used, based in turn on the concept of “local text” accepted in the scientific literature. The basic thesis is that one of the characteristics of local (regional, provincial) texts is their myth-generating function - the creation of mythological space, which reflects the features of the region. The novelty of the research is that the images of food and drinks has not been considered before as an element of the Vladivostok text, involved in the formation of the mythopoetic image of the city. On the basis of the novel “Vladivostok-3000,” all language units denoting food and drinks were singled out. The role of the corresponding images in the text is defined: products, dishes and drinks are a marker of the own and others; they act as a means of transformation of the hero; give him strength; symbolically fasten relations between characters; they are part of etiquette; become a bright marker of the fantastic space created by the authors. It is concluded that the images of food and drinks play an important role in the artistic transfer of the specificity of the city (real Vladivostok and fictional Vladivostok-3000), being a necessary element of the Vladivostok text

Leaf Mesophyll Structure and Photosynthetic Activity in Calla palustris L. from Natural Habitats with Different Level of Technogenic Pollution

A study of leaf structure and CO2 assimilation rate was conducted on the emergent plant Calla palustris L. from natural habitats with different levels of technogenic pollution (the Sak-Elga River, upstream and downstream of the Karabash copper smelter, Chelyabinsk region, Russia). It was found that both chlorophyll a content andthe rate of CO2 assimilation decreased twofold in plants from the downstream site. No significant changes were observed in leaf mesophyll structure and the volume of aerenchyma in the leaf. It was shown that in plants from strongly contaminated site, the decrease in spongy mesophyll cell volume was compensated by the increase in their number, whereas the decrease in the number of chloroplasts per cell was accompanied by a growth in volume. It is concluded that the changes in the numerical and dimensional characteristics of mesophyll cells and chloroplasts provide for the viability of C. palustris under prolonged technogenic impact and demonstrate the plasticity of the photosynthetic apparatus. Keywords: emergent plant, heavy metals, adaptation, leaf structure, CO2 uptak

Theory of differential inclusions and its application in mechanics

The following chapter deals with systems of differential equations with discontinuous right-hand sides. The key question is how to define the solutions of such systems. The most adequate approach is to treat discontinuous systems as systems with multivalued right-hand sides (differential inclusions). In this work three well-known definitions of solution of discontinuous system are considered. We will demonstrate the difference between these definitions and their application to different mechanical problems. Mathematical models of drilling systems with discontinuous friction torque characteristics are considered. Here, opposite to classical Coulomb symmetric friction law, the friction torque characteristic is asymmetrical. Problem of sudden load change is studied. Analytical methods of investigation of systems with such asymmetrical friction based on the use of Lyapunov functions are demonstrated. The Watt governor and Chua system are considered to show different aspects of computer modeling of discontinuous systems

Formalization of hydrocarbon conversion scheme of catalytic cracking for mathematical model development

The issue of improving the energy and resource efficiency of advanced petroleum processing can be solved by the development of adequate mathematical model based on physical and chemical regularities of process reactions with a high predictive potential in the advanced petroleum refining. In this work, the development of formalized hydrocarbon conversion scheme of catalytic cracking was performed using thermodynamic parameters of reaction defined by the Density Functional Theory. The list of reaction was compiled according to the results of feedstock structural-group composition definition, which was done by the n-d-m-method, the Hazelvuda method, qualitative composition of feedstock defined by gas chromatography-mass spectrometry and individual composition of catalytic cracking gasoline fraction. Formalized hydrocarbon conversion scheme of catalytic cracking will become the basis for the development of the catalytic cracking kinetic model

Specific nature of the integrative (complex) effect of environmental factors on hazelnut cultivars in the Russian humid subtropics

Corylus pontica K. Koch is a valuable nut crop. The expediency of the crop’s large-scale cultivation calls for measuring the parameters of agroclimatic indicators, ranging in variability, intensity, and duration of their impact. Environmental factors were assessed using phenological techniques based on recording the flowering and fruiting dates, recognized as the function demonstrating the complex effect of these factors on the hazelnut yield throughout the crop’s perennial cycle. Climate change urges the selection of adaptable cultivars for such areas where limiting factors are turning into stressors. Dependence of hazel cultivars on climate indicators (air temperature and humidity, and total precipitation) was observed in the phases of harvest formation. The crop’s genotypic diversity contributed to the specific nature of the complex effect produced by environmental factors. Peculiar responses of hazel plants to weather conditions in both flowering and fruiting phases were instigated by the biology of their development. Flowering started in January and depended on air temperature and humidity. Fruiting was affected by air temperatures and precipitation amounts (in July/August). Dependencies between yield and weather were well expressed, with module values of 0.86–1.0 (p < 0.05). The effect size of limiting factors is better measured with the coefficient of determination (%), a direct indicator of the correlations between harvest and weather factors. Flowering (I–III) under unpredictable conditions is regarded as a “critical” stage in the ontogenesis of hazel trees. No less critical is the fruiting phase, occurring simultaneously with the setting and differentiation of generative organs for the next year’s yield. Registration of limiting factors and their variations over the perennial plant cycle made it possible to recommend cvs. ‘Cherkesskiy-2’, ‘Anastasiya’, ‘Kristina’ and ‘Viktoriya’ as adaptable to the subtropics of Krasnodar Territory
