Glucosinolates with Brassica genus as secondary metabolites have a lot of functions and effects. Glucosinolates form less than 2% of the overall sulphur content at the beginning of vegetation in different parts of the plants and during growth their content is decreasing and forms less than 0.1%. This low representation doubts their storage function. With its chemical composition, they are ranked among natural pesticides with active and passive resistance against diseases and pests. They show repellent effects and properties of natural biofumigators in soil after ploughing in their biomass as green fertilizing, or after ploughing in after harvest the leftovers of rape. The principle of these effects is decomposition products of glucosinolates – bioactive isothiocyanates. Very important from this point of view are turnip rape Rex and Brassica juncea, whose content of these compounds is the highest one and they are resistant against the attack of Ceutorrhynchus pleurostigma. The same effect showed also when attacked by Phoma lingam. With other winter Brassicas either hybrid or linea and summer rape is this defensive system suppressed because of their lowered content due to breeding interferences, leading to limitation of their anti-nutritional negative effects. It is possible to state the final result after finding out the production of the above matter, roots, and after evaluation of the sorbal characteristics of the soil and evaluation of the state of health of the following crop or vegetable. After this overall analysis, it will be possible to evaluate the biofumigation properties of accessible varieties of the Brassica genus.

The decisive role of globalization processes and development tendencies has many positive and negative effects in economic (foreign-trade), environmental, and (bio) technological areas. From the evolution point of view still very successful human adaptation strategy hit the basic limit given by the capacity of the Earth biosphere. The evolution determinants of human society and their economic or technological activities manifesting themselves by global problems can find way out of sustainable development. The application of the so-called preventive principle represents a great dilemma.

Abstract What kinds of modern Canadian plays are most often translated or adapted for production elsewhere in Canada or overseas? How many modern Canadian plays are translations or adaptations of non-theatrical originals (novels, poetry, fairy tales)? Where can one find out if a translation of a Canadian play is available? These are among the questions addressed by the catalogue From Around the World and at Home: Translations and Adaptations in Canadian Theatre, the first comprehensive database of Canadian theatre translations. This paper examines the two basic questions of translation in Canadian theatre as revealed by the database, not from the usual point of view of one or several individual works looked at closely, but from the broader perspective of a large statistical overview: 1. What is the state of theatre translation within the borders of Canada? That is, what transfers are happening between linguistic groups within Canada? And what role do inter-generic translations play here? 2. Are there regional variations in terms of overseas influence? In other words, do different parts of Canada look to different parts of the world for theatrical sources? Published by Playwrights Union of Canada in 2001, the Catalogue contains over 3000 separate entries, including source and target references to Canadian plays translated for production or publication either inside or outside Canada, and Canadian plays which are themselves translations of other domestic or overseas pieces. With the term “translation” including generic as well as linguistic transfers, the Catalogue is designed to serve as both a reference source and the basis for more detailed analysis of the ongoing role of translation in Canadian theatre.

As an unethical behavior, plagiarism refers to using other people’s words or ideas without appropriately acknowledging the source (Delvin & Gray, 2007). Numerous scholars from different parts of the world have attempted to get into the root of this problem by identifying the underlying factors which contribute to such academic misconduct. In a similar vein, the present study aimed at examining the role of gender and educational level of Iranian EFL graduate students in determining the main reasons for plagiarism commitment from their point of view. To this end, a convenient sample of 159 M.A. and Ph.D. students partook in the study. To gather the necessary data, a 32-item Likert-Type questionnaire was administered whose results were subjected to a two-way MANOVA. Results of the study indicated that neither the students’ gender or educational level nor the interaction effect of these two variables had any significant effect on the reasons for engaging in plagiarism. Descriptive statistics, however, showed that students’ personal and attitudinal characteristics took on paramount importance compared to other factors. This can signal the intentionality of plagiarism among Iranian EFL graduate students, thereby suggesting the need for making more informed decisions on how to deal with this problem.

Objectives: In this commentary we emphasize the importance of breakfast for children, both from the point of view of proper nutritional education and as a strategy for the prevention of obesity. Methods: We reviewed the international literature, drawing particularly on information regarding the possible negative effects of skipping breakfast. Results: Obese children often do not eat breakfast and may face metabolic problems such as insulin resistance and hypercholesterolemia. The child who does not eat breakfast often becomes an adult who does not eat breakfast. The role of parents is fundamental in the acquisition of correct eating habits. Conclusions: The awareness that habits during childhood become elements of everyday life in adulthood, makes us understand the importance of the long-term consequences of skipping breakfast during childhood and adolescence.

An experimental investigation into interaction between language and information graphics in multimodal documents served as the basis for this study. More specifically, our purpose was to investigate the role of linguistic annotations in graph-text documents. Participants were presented with three newspaper articles in the following conditions: one text-only, one text plus non-annotated graph, and one text plus annotated graph. Results of the experiment showed that, on one hand, annotations play a bridging role for integration of information contributed by different representational modalities. On the other hand, linguistic annotations have negative effects on recall, possibly due to attention divided by the different parts of a document.

It has been almost universally adopted that dissolution of solids proceeds with development of uniform, continuous frontiers of reaction.However this point of view is doubtful / 1 /. E.g. we have proved the active role of the block (grain) boundaries in the main phases of cement, these boundaries being the areas of hydrate phases' nucleation / 2 /. It has brought to the supposition that the dissolution frontier of cement particles in water is discrete. It seems also probable that the dissolution proceeds through the channels, which serve both for the liquid phase movement and for the drainage of the incongruant solution products. These channels can be appeared along the block boundaries.In order to demonsrate it, we have offered the method of phase-contrast impregnation of the hardened cement paste with the solution of methyl metacrylahe and benzoyl peroxide. The viscosity of this solution is equal to that of water.

The article considers the role of trust in the economy, the mechanisms of its accumulation and the possibility of using it as one of the growth factors in the future. The advantages and disadvantages of measuring the level of generalized trust using two alternative questions — about trusting people in general and trusting strangers — are analyzed. The results of the analysis of dynamics of the level of generalized trust among Russian youth, obtained within the study of the Institute for National Projects in 10 regions of Russia, are presented. It is shown that there are no significant changes in trust in people in general during the study at university. At the same time, the level of trust in strangers falls, which can negatively affect the level of trust in the country as a whole, and as a result have negative effects on the development of the economy in the future. Possible causes of the observed trends and the role of universities are discussed. Also the question about the connection between the level of education and generalized trust in countries with different quality of the institutional environment is raised.

The purpose and tasks of the work are to analyze the contemporary Ukrainian mass culture in terms of its value and humanistic components, as well as the importance of cultural studies and Ukrainian studies in educational disciplines for the formation of a holistic worldview of modern youth.Analysis of research and publications. Scientists repeatedly turned to the problems of the role of spirituality in the formation of society and its culture. This problem is highlighted in the publications by O. Losev, V. Lytvyn, D. Likhachev, S. Avierintsev, M. Zakovych, I. Stepanenko and E. Kostyshyn.Experts see the main negative impact of mass culture on the quality approach, which determines mass culture through the market, because mass culture, from our point of view, is everything that is sold and used in mass demand.One of the most interesting studies on this issue was the work by the representatives of Frankfurt School M. Horkheimer and T. Adorno «Dialectics of Enlightenment» (1947), devoted to a detailed analysis of mass culture. Propaganda at all socio-cultural levels in the form is similar in both totalitarian and democratic countries. It is connected, according to the authors, with the direction of European enlightenment. The tendency to unify people is a manifestation of the influence of mass culture, from cinema to pop. Mass culture is a phenomenon whose existence is associated with commerce (accumulation in any form – this is the main feature of education), in general, the fact that it exists in this form is related to the direction of the history of civilization.Modern mass culture, with its externally attractive and easily assimilated ideas and symbols, appealing to the trends of modern fashion, becomes a standard of prestigious consumption, does not require intense reflection, allows you to relax, distract, not teach, but entertains, preaches hedonism as the main spiritual value. And as a consequence, there are socio-cultural risks: an active rejection of other people, which leads to the formation of indifference; cruelty as a character trait; increase of violent and mercenary crime; increase in the number of alcohol and drug addicts; anti-patriotism; indifference to the values of the family and as a result of social orphanhood and prostitution.Conclusions, perspectives of research. Thus, we can conclude that modern Ukrainian education is predominantly formed by the values of mass culture. Namely, according to the «Dialectic» by Horkheimer and Adorno, «semi-enlightenment becomes an objective spirit» of our modern society.It is concluded that only high-quality education can create the opposite of the onset of mass culture and the destruction of spirituality in our society. It is proved that only by realizing the importance of cultivating disciplines in the educational process and the spiritual upbringing of the nation, through educational reforms, humanitarian knowledge will gradually return to student audiences.Formation of youth occurs under the influence of social environment, culture, education and self-education. The optimal combination of these factors determines both the process of socialization itself and how successful it will be. In this context, one can see the leading role of education and upbringing. It turns out that the main task of modern education is to spread its influence on the development of spiritual culture of the individual, which eventually becomes a solid foundation for the formation of the individual. Such a subject requires both philosophical and humanitarian approaches in further integrated interdisciplinary research, since the availability of such research will provide the theoretical foundation for truly modern educational and personal development.

Relevance. Grain is the key to strategic products to ensure food security. From this point of view, the creation of large grain farms is a matter for the country's selfsufficiency and it leading to a decrease in financial expense for import. Creation of such farms creates an abundance of productivity from the area and leads to obtaining increased reproductive seeds. The main policy of the government is to minimize dependency from import, create abundance of food and create favorable conditions for export potential.The purpose of the study: the development of grain production in order to ensure food security of the country and strengthen government support for this industry.Methods: comparative analysis, systems approach.Results. As shown in the research, if we pay attention to the activities of private entrepreneurship in the country, we can see result of the implementation of agrarian reforms after which various types of farms have been created in republic.The role of privateentrepreneurshipinthedevelopmentofproduction is great. Тhe article outlines the sowing area, production, productivity, import, export of grain and the level of selfsufficiency in this country from 2015 till 2017.
