In continuous studies regarding the conservation of the advantageous condition of the soil structure, the highland plantations that are surrounded by living waters have major importance where the erosion of the soil, nutrients and chemicals endangers the quality of the water and the living world of the waters. At the same time the extreme weather and dry summers of the past years have made it important to look for soil cultivation solutions and technologies that are capable of decreasing the evaporation of the soil, for enhanced conservation of soil moisture and to improve the soil structure that is required for the growth of healthy roots. In our experiment we have studied soil mulching with organic plant residue, by sods and the effect of the mechanical cultivation on the soil and on the grape through two growing seasons. From the studied treatments, the mulching with organic plant wastage showed the most efficient results from the point of view of the nutrient distribution in the grape and yield. It also had a positive effect on the soil structure and humidity.

Topicality. Nowadays, crewing business in Ukraine is at the stage of formation and development, so its study is a rather new topic for modern Ukrainian science. The study of the problem of considering the crewing business from the point of view of rising the quality of the labour force in the seafarers' labour market, highlights the features of modern interaction between the subjects of the maritime segment of the labour market in terms of the effectiveness of work with marine personnel, helps to orient work in the maritime industry at the state level in the direction of risk reduction and maximum elimination of threats of the present for a modern shipping company, it is necessary to ensure the safety of seafarers in the legal and operational field, which is the basis of this scientific article. Aim and tasks. The aim and tasks of the study are to determine the features of modern interaction between the subjects of the maritime segment of the labour market: the shipowner, the crewing company and the seafarer to design further ways to develop crewing activities. Research results. The article considers the features of the interaction between the subjects of the maritime segment of the labour market: the shipowner, the crewing company and the sailor in the modern dimension of the development of crewing activities. The commercial relationship between the interests of the customer and the intermediary in the selection of a successful skilled employee is analysed. Threats to the development of the modern maritime industry, affecting the labour market of seafarers, have been identified. The ways of further state regulation of the activities of crewing companies in Ukraine on the employment of seafarers and ensuring their protection in any port of the world are covered. Conclusion. The value of the work is determined by the small number of publications on this topic. In Ukraine the opportunity to ensure the protection of seafarers is conditioned by a new state policy, it provides for the introduction of new laws and regulations in the maritime industry, they are aimed at supporting seafarers working on ships on international voyages. The adoption of positive state decisions in the shortest possible time is a way to strengthen international cooperation in ensuring the observance of the labour and social seafarers� rights, their guarantees, ultimately, it will have a positive effect on the development of crewing activities in our country.

Without knowing the main quality indicators of agricultural products, it is impossible to draw conclusions about the effectiveness of this or that agro-technical measure. One of the factors influencing the quality of sugar beet and watermelon is the effective application of fertilizers. Fertilizers increase the quality indicators of the product along with its expansion. From this point of view, the effect of organic and mineral fertilizers on the quality indicators of sugar beet and watermelon product in the meadow-gray soils of Mugan-Salyan region was studied. The combined application of organic and mineral fertilizers had a positive effect on the quality indicators of sugar beet and watermelon. Key words: organic and mineral fertilizers, sugar beet, watermelon, phosphorus, potassium, productivity, soil, quality

A field experiment was conducted at Bangladesh Jute Research Institute (BJRI) to observe the response of N, P, K and S on a pre?released white jute (Corchorus capsularis) var. BJC?2197. The experiment was carried out by applying N, P, K, S fertilizers in ten combinations including control. From the experiment it was observed that all the treatments had significant positive effect over control on growth, yield and quality parameters. The highest fiber yield (3.21 t/ha) and stick yield (6.58 t/ha) were recorded with N90P5K30S10 kg/ha treatment. However, the best quality fiber was found with combination of N90P15K30S10 kg/ha treatment. From the economic analysis point of view, it was found that combination of N90P5K30S10 kg/ha was higher (2.30) than N90P15K30S10 kg/ha (2.04). So the former can be considered as the best combination for var. BJC?2197 in terms of BCR, yield and quality. Dhaka Univ. J. Biol.

The immediate problem confronted by readers of Martha Nussbaum's early work is that, from a professional point of view, the quality of mind behind the arguments seems far superior to the arguments themselves. From the point of view of the academic philosopher, Nussbaum is far too heavily invested in literature; while, from the point of view of the professional literary critic, she is far too deeply committed to a principle of realism, even to an affective relationship with literary characters, that is incompatible with academic norms. The central idea in her early work is not in fact conceptual or critical at all, but rather moral: a fundamental transformation of life based on a relinquishing of mastery,a submission of the mind to emotion, especially erotic emotion. Nussbaum has commented on the formative impact of an adolescent reading of Plato's Phaedrus, in which she identified herself with the younger partner of the Platonic homosexual couple, the apprentice learner bound to the master by erotic and intellectual ties, and we can see in Nussbaum'searly work residues of this identification. In ''phase two'' of Nussbaum'swork, we can, however,trace a further conversion, in which Nussbaum positions herself not as the apprentice but as the master. In most of the work she has produced since the late 1980s, the values and orientations of her early work are precisely inverted: emotions are now checked or carefully contained, an emphasis on erotic passion is transformed into a zeal for social and educational reform, the personal gives way to the cosmopolitan and even the universal; Stoic or Kantian reason becomes the dominant emphasis as Nussbaum attempts to articulate a general account of ''the human.'' Nussbaum's public disputes over the past decade reveal, in addition to the differences that continue to separate her from her contemporaries, a complex attempt to negotiate the differences that divide her from herself. The most characteristic gesture of the work of the past ten years is an often-revised ''List of Human Capabilities'' that she proposes as a way of guiding quality-of-life assessments, especially in developing nations. The conception behind such a list may represent, as her critics charge, a grossly unprofessional failure of professionalism, as well as moral arrogance; but it may also, perhaps, actually be useful.

The article is devoted to highlighting the author’s views on the theoretical aspects of the application of a synergetic approach to the formation of the economic potential of the modern territorial community. It is established that the potential of the territorial community characterizes many opportunities for its development in terms of using the full range of its resources, features of the past, current and planned structure of its economy, geographical location and other factors. Systematic, reproductive and resource approaches to determining the content of economic potential are described. Particular attention is paid to the system approach, which allows to reveal such aspects to the interpretation of the content of economic potential as elemental, structural, functional, integral and historical. The content and elements of the economic potential of the territorial community are proposed to be considered from the point of view of its resource provision; ability to structure and readiness to carry out socio-economic transformations; formation of the market environment; level and quality of community life; areas of implementation. It is established that since the economic potential of a territorial community is a complex heterogeneous system, synergetics should be applied to its study, which allows to explain the complexity and diversity of social relations and processes occurring in the territorial community, as well as to substantiate the content and logic of its economic potential. The formation of the economic potential of the territory should take into account the systemic principles of the synergetic concept, namely: self-organization; self-reproduction; subordination; openness; resonant influence; instability; constant fluctuations; bifurcation of development; multivariate development; dynamic hierarchy; nonlinearity; interconnection, interaction and interchangeability of system elements.

The article aims at focusing attention at selected aspects of pop culture which may, from the point of view of evolutionary psychologists, be deemed approximate to animal proto-cultures and social systems observed among the three-year-olds, i.e. — people who have not yet developed a psychological skill called “theory of mind”. The Author tries to point out that elements of proto-culture in the time of pop -industry development gain on dominance, as a result of which the quality of culture creating processes as well as culture transmission processes may be different than, let’s say, fifty years ago. It is not only about the mass media, but it is most of all about deep psychological processes which are the basis for understanding the essence of culture and participation in culture. In other words, the author tries to argue that norms, ideas and values, i.e. what culture is made of in general — are understood and disseminated in ways which are different in quality from the ones prevailing in the past.

Yield and quality responses to Galmi Violet, Galmi White and Sumrana Violet were studied during 1990-91 and 1991-92 in Maradi region in Niger. Three regimes comprised of irrigating when the soil moisture depletion in 20 cm of soil depth was 40%, 60% and 80%. Investigations were carried out both under field conditions and in the lysimeters. The soil was sandy loam to loam. The lysimeters were 2m×2m×1m drainage type and well set over the past twenty years. The crop was raised during the dry season from October to March with no rainfall. Despite the low temperatures the radiation levels were high. Onion yield was higher under low irrigation regime. The mean yield was 32.5 tons/ha. However, the bulk density was higher under higher moisture regimes. The keeping quality over eight month period was not affected by soil moisture regimes. The bulbs of Sumrana Violet were of medium size whereas the bulbs of Galmi Violet and White were larger size. From a market acceptability standpoint violet onions were preferred over the white ones.

Over the past 20 years, research on quality of experience (QoE) has been actively expanded even to cover aesthetic, emotional and psychological experiences. QoE has been an important research topic in determining the perceptual factors that are essential to users in keeping with the emergence of new display technologies. In this paper, we provide in-depth reviews of recent assessment studies in this field. Compared to previous reviews, our research examines the human factors observed over various recent displays and their associated assessment methods. In this study, we first provide a comprehensive QoE analysis on 2D display including image/video quality assessment (I/VQA), visual preference, and human visual system-related studies. Second, we analyze stereoscopic 3D (S3D) QoE research on the topics of I/VQA and visual discomfort from the human perception point of view on S3D display. Third, we investigate QoE in a head-mounted display-based virtual reality (VR) environment, and deal with VR sickness and 360 I/VQA with their individual approach. All of our reviews are analyzed through comparison of benchmark models. Furthermore, we layout QoE works on future display and modern deep-learning applications.
