Stress factors limit the development of living organisms, especially plants, and reduce their productivity. In this regard, the study of the effects of stress factors on plants and the discovery of adaptation mechanisms play an important role in the regulation of stress in the cell. From a biological point of view, stress is considered to be any change in the external environment that impairs the normal development of the plant or changes it in a negative direction. Stresses cause changes in the physiological activity of plants, weaken the process of biosynthesis in the cell, disrupt normal life and ultimately can cause plant death.

In the emergence, development and flow of epizootics, environmental features are often not taken into account as causative agents of infectious diseases – stability in the external environment, range, adaptation to different types of animals, and vectors and reservoir of pathogens. Epizootology, studying the ecological interrelations of animals, reveals the patterns of prediction of epizootics, the elucidation of which is essential for the development of a plan for antiepizootic measures. A rational plan of measures, developed on the basis of an informed forecast, ensures its effectiveness.Epizootological geography, which studies the spread of infectious animal diseases in various natural and geographical conditions, allows us to disclose the significance of various external factors. In addition, with its help you can not only describe the territory of the spread of various infectious diseases, but also explain the geography of diseases, the history of their origin and development. As a result, it is possible to draw up prognostic maps that identify areas with favorable and unfavorable conditions for the spread of diseases and give predictions of some epizootics that occur seasonally or after a certain number of years. A significant number of infectious diseases are anthropozoonoses, and the areas of their spread are associated with physical and geographical zones in which natural foci are historically formed.The study of epizootology, from the point of view of ecology, enriches the knowledge of epizootological regularities. The ecology of animals studies the interrelationships of living organisms, the way of their life in connection with the conditions of existence in the environment, the dynamics of the number of species and the peculiarity of biocenoses.

This review focuses on the ability of some natural antioxidant molecules (i.e., hydroxycinnamic acids, coumarin-3-carboxylic acid, quercetin, luteolin and curcumin) to form Al(III)- and Fe(III)-complexes with the aim of evaluating the coordination properties from a combined experimental and theoretical point of view. Despite the contributions of previous studies on the chemical properties and biological activity of these metal complexes involving such natural antioxidants, further detailed relationships between the structure and properties are still required. In this context, the investigation on the coordination properties of Al(III) and Fe(III) toward these natural antioxidant molecules might deserve high interest to design water soluble molecule-based metal carriers that can improve the metal’s intake and/or its removal in living organisms.

The two most important deviations from the normal life-history of ferns, apogamy and apospory, are of interest in themselves, but acquire a more general importance from the possibility that their study may throw light on the nature of alternation of generations in archegoniate plants. They have been considered from this point of view Pringsheim, and by those who, following him, regard the two generations as homologous with one another in the sense that the sporophyte arose by the gradual modification of individuals originally resemblin the sexual plant. Celakovsky and Bower, on the other hand, maintaint the view tha t the sporophyte, as an interpolated stage in the life-history arising by elaboration of the zygote, a few thallophytes.

This study compares males and females perception of the effect of social media on their social interaction to understand the difference between both genders. The study follows a mixed-method methodology using a questionnaire with closed-ended items and open-ended questions. Responses to the questionnaire are collected form 207 male and female students from a public university in Saudi Arabia. In general, the results of the questionnaire are insignificant which indicate that there are no differences between both genders. However, the results of the open-ended questions show that females have a negative view of the effect of social media on human relations while males have a positive point of view. However, both genders have a positive point of view regarding balancing between friends and family in real life and virtual world through time management.

Purpose. Problems of the existing theory, methodology and organization of accounting need to be solved taking into account practical requirements of modern management. In turn, this provides an opportunity to expand the functionality of accounting to make informed decisions, focused on achieving the efficiency of business operations and maximize the value of business, which contributes to the increased importance of accounting in management. This testifies to the relevance of the chosen topic , which determined the directions of the research, which requires in-depth scientific research, its scientific-methodological and practical importance. Purpose. The purpose of the article is to systematize existing approaches and to improve the classification of accounting functions in accordance with the requirements of the management system. Methods. In the process of researching the growth of accounting functionality in the management of agrarian business used general scientific methods of knowledge of reality, including: structural-logical and semantic analysis - to clarify and streamline the terminology in the conceptual apparatus; induction and deduction - for parameterization of accounting functionality in management; grouping and classification - to develop methodological principles and systematize the classification features of accounting functions. The research is based on general and specific methods of studying the economic processes, facts and phenomena of management requests for increasing the functionality of accounting for agricultural business management. The scientific base of the research was scientific works of domestic and foreign scientists on accounting functions in the management system, materials of international scientific-practical conferences and seminars, results of personal experience and observations. Results. Accounting as an information system, which is designed to make operational and strategic management decisions, needs to expand its functionality and increase its tasks. These categories have become one of the main ones in accounting, but also in management, as indispensable tools of managerial relations in business. Today, accounting is facing a scientific problem that needs theoretical and methodological justifications and practical solutions. It is necessary to expand the functionality of accounting in agrarian enterprises in order to meet management requests focused on achieving the strategic goal of the enterprise and maximize the value of business. The analysis of the evolution of information requests of the branch management and the priority of accounting functions in the development of agrarian business makes it possible to conclude that the priority task characterizes the process of information support for customers and consumers. According to the results of studying the classifications of functions, we have concluded that most often the scientists indicate the information function, the second most important is the control, and then the analytical and evaluation. Considering different approaches of scientists to classification of accounting functions and summarizing the results of the research, we concluded that the existing set of accounting functions does not allow to fully fulfill the tasks set before it. Therefore, in the current conditions of development of the global economy, the solution of this problem requires both theoretical and methodological justifications. That is why an important component of increasing the importance of accounting in the management of agrarian business is the expansion of its functionality, in particular by isolating new objectively formed functions. Given the priority of accounting functions in the development of agrarian business, they should be classified according to the information requests of the management system, as a result of which we propose to introduce a cost-oriented function and the function of saving capital and economic security of business. The capital saving function is a tool through which the formation of equity, regulation of property relations and business management, which provides a legal platform for completeness of payments with owners and guarantees the economic security of the enterprise. This function will facilitate the management of capital formation and its use. The value-oriented function is based on creating the market value of the business or providing the assets with the characteristics of the most valuable investments. It reflects the change in the value of the property of the enterprise from the point of view of transformation of its value in the external environment and allows to better understand the alternative advantages of investment sources. The proposed functions are aimed at identifying the degree of participation of owners in the management of the business entity, completeness of payments with them and determining the market value of agricultural businesses, increasing the investment attractiveness of Ukrainian agricultural enterprises. Discussion. Further scientific research in the direction of increasing the functionality of accounting in the management of agricultural business, it is advisable to carry out on the basis of domestic and foreign experience where the basis is the assertion that is built on the basis that accounting becomes the main function of management, which will facilitate the implementation of all functions of the management system. This will allow you to determine the place of accounting functions in achieving the goal of the management system, which will help in the formation of feedbacks between management and accounting. In-depth study of accounting functions will create the basis for improving the theoretical and methodological level of its development and will enhance functionality in the management system of agricultural business. Functional approach will allow to study the object of accounting not from the point of view of internal structure, set of interrelations of elements of its system, but on the other hand - interrelations with the external environment.

The conditions for doing business at this stage are often similar in a game in which you need to calculate your actions a few steps ahead. At the same time, it is important to highlight several possible current options and make the necessary decision at the control moment. Moreover, each of the options formed should be justified, understandable and take into account the risk factors and available resources.Today, the main problem of assessing and minimizing the risk of “unfriendly takeover” is due to the fact that in most cases the raider is a player who acts quite legitimately and relies on the loopholes of the current legislative framework. Therefore, it is easier to identify possible actions of the raider and to avoid them within the limits of the reverse game than to deal with the consequences.The purpose of the research is to study the specificity of the individualized assessment and minimization of the risk of “unfriendly takeover” by using elements of game theory.It has been taken into account that the effect of individualization in assessing the risk of unfriendly takeover of enterprises can possibly be achieved on the basis of the application of game theory, the elements of which provide simulation of the unfriendly takeover process within the mathematical description of the inherent combinations of attack/defence as if they actually occurred in time both within one state of the external environment and for their given set.The results allowed forming mathematical decision-making models based on the elements of the antagonistic game “raider-target enterprise” and “raider games with the external environment”, which proved the possibility to: 1) identify possible functions of wins/losses; 2) combinations of attacks that can be neglected (that is, from the point of view of the rationality of decisions, will be rejected by the raider); 3) the ranking of the raider’s “attack combinations” for the reliability of their use during “unfriendly takeover”. Under such conditions, the target company can provide not only a detailed assessment, but also an effective minimization of the risk of “unfriendly takeover” and allocate the best combination of protection.

There is no generally accepted definition of a territory’s mission either in Russia or abroad. So is it worth including a mission in the strategy of socio-economic development of a territory and what definition of the mission is better to choose? To answer these questions, a content analysis of Russian and foreign definitions of the territory's mission has been carried out, from which common units of meaning were identified. It was established that a number of semantic units in definitions of the territory's mission and the mission of organization coincide. However, from the point of view of the mission statement, there are a number of significant differences between a territory and an organization, which makes some definitions of the territory’s mission hardly applicable in practice. Conclusion is made: it is better to define the territory's mission through its role in the external environment, functions and unique features of the territory. The article examines advantages and disadvantages of alternative options: not to develop a mission at all or to develop it in a purely formal way. Practical recommendations on developing a territory mission, examples from Russian and foreign experience are given.

Proteins play a vital molecular role in all living organisms. Experimentally, it is difficult to predict the protein structure, however alternatively theoretical prediction method holds good for it. The 3D structure prediction of proteins is very much important in biology and this leads to the discovery of different useful drugs, enzymes, and currently this is considered as an important research domain. The prediction of proteins is related to identification of its tertiary structure. From the computational point of view, different models (protein representations) have been developed along with certain efficient optimization methods to predict the protein structure. The bio-inspired computation is used mostly for optimization process during solving protein structure. These algorithms now a days has received great interests and attention in the literature. This chapter aim basically for discussing the key features of recently developed five different types of bio-inspired computational algorithms, applied in protein structure prediction problems.
