Modern plant protection should be as environmentally friendly as possible, therefore, agrotechnical methods should form its basis. The current paper has presented the results of three-year study (2017–2019) of the effect of nitrogen fertilizers and seeding rates on the brown mustard productivity and its ability to suppress weeds. The study was carried out in the Central steppe of the Crimea on the southern low-humus blackearth (chernozem) by the researchers of the FSBSI “Research Institute of agriculture in Crimea”. The purpose of the current study was to determine the effect of nitrogen fertilizers and seeding rates on the productivity and competitiveness of brown mustard. There was found that the amount of weeds depends on the individual weediness of the field and the conditions of moisture supply of the year. By the time the mustard was harvested, the number of weeds increased by almost 1.5 times due to the emergence of new shoots of weeds during the ripening period of mustard. There has been presented the dynamics of dry weeds weight depending on the seeding rate. There has been shown that the growth and development of weeds depends on the density of the brown mustard sowings. With an increase in the seeding rate from 0.5 to 3.0 million pieces per hectare, the dry weeds weight decreased from 180.8 to 44.3 g/m2  on average over three years. An increase in the seeding rate from 2.5 to 3.0 million pieces per hectare did not provide a significant decrease in dry weeds weight. There has been established that the optimal seeding rate for growing brown mustard in the Crimean steppe is 2.5 million pieces per hectare. At this seeding rate, mustard sowings are maximally productive (0.77 t/ha) and are characterized by a high competitive ability to weeds. There has been proven a positive effect of nitrogen fertilizers on brown mustard productivity and growth in the number of weeds. The highest mean productivity of oilseeds for three years was obtained with the application of nitrogen doses N60 and N80 and was 0.78–0.81 t/ha (on 0.28–0.31 t/ha more than that of the control). In the same variants, dry weeds weight was the highest (105.4–106.5 g/m2 ).

This article is devoted to the studying hermeneutic circle in the development of methodological culture of future music teacher. Under the conditions of globalization processes, tendencies of convergence of world cultures improvement of culturological training of student youth requires new approaches, in particular, culturological training of students of pedagogical specialties. The task of pedagogical education is to develop a teacher as a specialist and as a person of high culture, who has a special positive effect on the personality of school student. This article analyses the works of scientists dedicated to the issues of establishment and development of the hermeneutic approach in philosophical, psychological, and logical and gnosiological contexts. It is defined the essence of the concept of “hermeneutic circle” as one of the basic principles of the hermeneutic approach. There have been provided the examples of interpretation of the principle of hermeneutic circle by various scientists. Hermeneutic approach is applied in sciences such as pedagogy, psychology, economics, sociology etc. In pedagogical science the hermeneutic approach at the level of conceptual use was elaborated by A. Zakirova. She introduced the term “pedagogical hermeneutics”. Hermeneutic circle as a principle of text understanding is based on the interrelation of the part and the whole. Understanding of the whole consists of the understanding of the individual parts, and understanding of the parts requires understanding of the whole. The concepts of the part and the whole are correlated: the text is a part concerning the whole creative activity of the author, which in its turn is a part of the particular genre or literature in general, as well as the part of spiritual life and biography of the author. The idea of hermeneutic circle means also that there is no understanding of the text without certain prerequisites: understanding is preceded by some idea of what is yet to understand. There have been determined the peculiarities of the use of the principle of hermeneutic circle in the development of methodological culture of the future teacher of musical art. In light of hermeneutical trends, the penetration of which in the realm of musical art can be traced quite clearly, the use of the hermeneutic circle principle in the development of methodological culture of the future teacher of musical art appears not only in the narrow interpretation of the particular phenomenon or group of phenomena, but much wider — as a means of learning and understanding of the worldview by a person.


The functional properties of marine invertebrate larvae represent the sum of the physiological activities of the individual, the interdependence among cells making up the whole, and the correct positioning of cells within the larval body. This chapter examines physiological aspects of nutrient acquisition, digestion, assimilation, and distribution within invertebrate larvae from an organismic and comparative perspective. Growth and development of larvae obviously require the acquisition of “food.” Yet the mechanisms where particulate or dissolved organic materials are converted into biomass and promote development of larvae differ and are variably known among groups. Differences in the physiology of the digestive system (secreted enzymes, gut transit time, and assimilation) within and among feeding larvae suggest the possibility of an underappreciated plasticity of digestive physiology. How the ingestion of seawater by and the existence of a circulatory system within larvae contribute to larval growth and development represent important topics for future research.

Objective:The Scripps neurologic rating scale (SNRS) is a summary measure of individual components comprising a neurological examination, designed for use in multiple sclerosis (MS). Our objective is to evaluate the responsiveness of the SNRS, within the context of a 2-year, randomized, double-blind crossover study of the efficacy of cladribine for treatment of secondary progressive MS.Methods:Effect sizes were determined for the SNRS and its components, separately for each treatment group (initial placebo, and initial cladribine) over both years of the clinical trial, using a standard random effects model.Results:Individual components tended to show positive effect sizes (improvement) during periods of active therapy in both treatment groups, and negative effect sizes (deterioration) during periods of no active therapy. Summation indices derived from the individual components of the SNRS seemed somewhat more stable than the individual components. The two components mentation and mood, and bladder, bowel, or sexual dysfunction, were rather unresponsive in our clinical trial.Conclusion:Changes in the components of the SNRS over the course of our clinical trial were consistent between the two treatment groups. Most components were moderately responsive; and, the summary SNRS score appropriately summarized the moderate magnitudes of change evinced in the individual components.

This paper scrutinizes the impact of intolerance toward diverse ethnic, religious, and cultural groups on an individual’s willingness to actively engage in non-violent protest. Following new insights, we examine the individual as well as the ecological effect of social intolerance on protest behavior. Drawing from insights of social psychology and communication science, we expect that the prevalence of intolerance reinforces the positive effect of individual-level intolerance on protest participation. From a rational choice perspective, however, a negative moderating effect is expected, as the expression of opinions becomes redundant for intolerant individuals in an intolerant society. We base our multilevel analyses on data from theWorld Values Surveyscovering 32 established democracies. Our results reveal that intolerance leads to more non-violent protest participation. This relationship, however, is strongly influenced by the prevalence of intolerance in a country.

As the Bahá’í Faith emerges from obscurity, Bahá’í scholars will have an important role in three fields: the presentation of Bahá’í Faith to the world; the defense of the Bahá’í Faith from attacks; and the intellectual growth and development of the Bahá’í community. This paper discusses the question of the place of scholarship in the Bahá’í community. The value of Bahá’í studies to the Bahá’í community is analyzed. The problems that may arise for Bahá’í scholars in relation to their own spiritual life and also in relation to the Bahá’í community are discussed. Some suggestions are then made with regard to the question of what academic approaches are most likely to be fruitful in the study of the Bahá’í Faith. Finally, consideration is given to the mutual obligations of the Bahá’í scholar and the Bahá’í community (in particular, the Bahá’í administrative institutions). Every Bahá’í who surveys the vast range of doctrines and concepts enshrined in the holy writings of the Bahá’í Faith or whose imagination is captured by the intensity of its brief history must, to some extent, be inspired to make a more thorough study of some aspect that interests him or her. To some is given the good fortune to have both the opportunity and inclination to put this study on a more formal basis. Whether this be at an institute of learning or through private study and research, there are many areas of the teachings and history of the Bahá’í Faith that invite painstaking research and thoughtful analysis. Such study is of great benefit to the Bahá’í community as a whole, quite apart from the immense satisfaction that it can bring to the individual student. There are also dangers in such study, particularly for the individual concerned, and often the extent of this danger is not appreciated by someone just setting out on such a course of study.

This study wanted to determine the ethical perceptions of students from the individual side of accounting students at FE UNP, namely from the emotional intelligence and ethical sensitivity of students. The author makes students the object of research because an accountant's ethical perceptions can also be influenced by several factors. One of them is external factors, namely the environment. The environment affects the formation of a person's character so that it affects their behavior. This research is classified as a causative research. The population used in this study were accounting students at the Padang City College. Samples were taken using purposive stratified sampling technique. Where is the sampling by taking samples of people selected by the author according to specific characteristics and certain characters. The analysis used in this study is multiple linear regression analysis used in this study is to use the SPSS 21 computer program. . The results of this study are that emotional intelligence has a positive effect on students' ethical perceptions as prospective accountants and ethical sensitivity has a positive effect on students' ethical perceptions as prospective accountants.

Direct seeding techniques often result in unsatisfactory outcomes in rangeland rehabilitation, primarily because of low seedling emergence and poor establishment. Seed processing techniques aimed at improving seedling emergence have gained interest by pasture managers. The purpose of this study was to investigate the combined effects of bracteole removal and seeding rate on seedling emergence in seven halophytic species: Atriplex halimus, A. canescens, A. leucoclada, A. nummularia, A. lentiformis, Salsola vermiculata and Haloxylon aphyllum under semi-arid conditions in Tel Hadya (Syria). Each of these species was evaluated for seedling emergence under two seed treatments (bracteoles removed and non-removed bracteoles) with three seeding rates (10, 30 and 60 seeds per pot), in a completely randomised block design. The results showed a positive effect of seed treatment on seedling emergence for all studied species. The native A. halimus had the highest emergence percentages whereas the introduced A. mummularia, had the lowest. However, there were no significant effects of seeding rates on seedling emergence. These results showed that bracteole removal could improve germination and seedling emergence, and potentially increase the rate of establishment of the species studied. Therefore, when implementing rangeland rehabilitation projects, bracteole removal needs to be considered. The native S. vermiculata should be recommended for direct seeding in the West Asia and North Africa region given its high seedling emergence, known high palatability, nutritive value, and high auto-regeneration performance.

The prime need of this world is that the simplest agriculture which decides the event of each country because the survival of the individual is completely obsessed with farming and its best production. Climate changes are in response to changes within the hydrosphere, biosphere, and other atmospheric and interacting factors. Human activities driven by demographic, economic, technological, and social changes have a big impact on activity. The climate influences the incidence further as the temporal and spatial distribution of plant diseases. the foremost factors that control the growth and development of diseases are temperature, light, and water. Climate affects all life stages of the pathogen and host and poses a challenge to many pathosystems. The environmental change, especially when combined with the pathogen and host introductions, may cause unprecedented effects.
