СULTURAL EPOCHS AS TEXT IN LESIA UKRAINKA’S DRAMAS

Based on Lesia Ukrainka’s dramas “Iphigenia in Tavrida”, “Cassandra”, “The Orgy”, “Ruphin and Priscilla”, and “The Stone Master”, the paper highlights peculiarities of cultural and historical codes of the Antiquity and the Middle Ages in the writer's works as well as literary manifestation of the world-view features of European and Ukrainian Modernism in the antique and medieval images and motifs. Lesia Ukrainka reconsidered the heritage of archaic and late Antiquity, Hellenistic period, Galilee at the time of Jesus, Early Christianity, and Medieval Spain. Each of these epochs has its own dichotomy of social and biological phenomena, parameters of the world model, and dominant fundamental points. Lesia Ukrainka’s dramas transform the material of various cultural epochs, providing polysemantic images that transfer the cosmos of a certain period into the neo-romantic and neo-classical system of images and symbols. In the dramas, the writer raised the issues recurrent in her works, such as love and sacrifice; beauty and ugliness; prophet, artist and ‘revolt of the masses’; reality and dream; good and evil; truth and benefit; nostalgia for chivalry; nostalgia for the Absolute; psychological and moral freedom and violence; spirit, soul, and body; spiritual nobility and the rule of brutes; nature and culture, etc. Numerous issues and characters, multifunctional ontological, cultural, and historical phenomena, cultural codes, symbols, and mythologems acquire an existential meaning in the author’s dramas fitting not only into various cultural contexts but also into the modern reconsideration of mythopoetics.

Distance/mixed education: features of perception of student youth

The aim of the study is to determine the attitude of higher education students of medical and physical and mathematical profile to distance / mixed learning (DL/ML) and its impact on their academic success. An anonymous online survey of 799 students (medical and physical and mathematical profile of study). The issues concerned various aspects of the organization of DL/ML. The obtained data were processed in IBM SPSS Statistics 22. It was found that half of medical and physical and mathematical students are positive about the use of DL/ML in the future (52.19%). One third of the respondents strongly oppose the continuation of distance education (34.79%). Moreover, students of physics and mathematics more often (p<0.05) determined the absence of differences between these forms and were more likely to return to the classical system of education. Applicants for physics and mathematics noted that virtual laboratory work is possible in the future (p<0.05). Medical students were more in favor of online knowledge control (p<0.01). Almost 70% of students in both groups noted that during DL/ML there was more free time, 1/3 of students affirm that their academic performance has improved and in general DL/ML did not affect on the desire to study, and a quarter of respondents noted that they used a part of free time at DL/ML for self-study, attending numerous scientific forums. According to the results of the survey, 80% of both groups had free time due to the exclusion of travel time. The study also showed that the effectiveness of training in a third of respondents was negatively affected by lack of factual information, lack of communication with classmates and teachers, and insufficient concentration, especially in the group of physical and mathematical profiles of study (p<0.05).

Experimental study and mathematical modelling of self-oscillation at the electrode-magnetic fluid interface in an electric field

The article describes a mathematical model of self-oscillation in the form of a boundary value problem for a nonlinear system of partial differential equations, with a numerical solution. The numerical results were compared to the experimental data to confirm the adequacy of the model. The model uses the classical system of differential equations of material balance, Nernst-Planck and Poisson equations without simplifications or fitting parameters. The aim of the article was to study the parameters of concentration self-oscillation in a layer of the dispersed phase particles of magnetic fluid at the interface with an electrode in an electric field. For this purpose, we developed a mathematical model, the consistency of which wasconfirmed by the corresponding physical mechanism.As a result of numerical experiments, we found the critical value of the potential jump after which self-oscillation began. We also determined the oscillation growth period and other characteristics of the process. We developed software called AutoWave01 with an intuitive user interface and advanced functionality for the study of self-oscillation in a thin layer of magnetic colloid.

Economic and bioenergy efficiency of sunflower cultivation depending on agricultural receptions

When assessing the economic efficiency of sunflower production in enterprises, it is necessary to correctly determine the system of interrelated indicators that should most objectively reflect its level. The aim of the research was to determine the economic and bioenergetic efficiency of sunflower cultivation depending on the method of basic tillage, dose of mineral fertilizers and growth regulators. The studies were conducted in 2016-2018 at the fields of the Institute of Oil Crops of the UAAS. The sowing was carried out at a depth of seed wrapping of 6-7 cm with a row spacing of 70 cm with a seeding rate of 50 thousand similar seeds per hectare. Basic tillage systems: classic – two-track disc, plowing (PN-3-35) to a depth of 22-25 cm; bottomless – two-track disc, endless tillage (KLD-3.0) to a depth of 25-27 cm; minimal – two-track discus, cultivation (KPS-4,0) to a depth of 10-12 cm. Mineral fertilizer application options: 1. Control – no fertilizer, 2. N40, 3. N40P60, 4. N60P60K60. Application options: 1. Control – treatment with water (250 l/ha), 2. Rost- concentrate + Oil gelatin (6-8 pairs of true leaves), 3. Forte gelatin + Mono boron gelatin (6-8 pairs of true leaves), 4. Mono boron chelate + Phosphate-potassium chelate (6-8 pairs of true leaves), 5. 1 treatment: Phosphate-potassium chelate + Multimix gelatin + Mono boron chelate (3-4 pairs of true leaves), 2 treatment: Mono gelatin boron (6-8 pairs of true leaves). The highest yield of sunflower hybrid Ratnik – 3.46 and 3.45 t/ha obtained by cultivation under the classical system of basic tillage, fertilization at a dose of N60P60K60 for pre-sowing cultivation and the second and fifth variants of application of the preparations: 2. Growth concentrate + Oil gelatin (6-8 pairs of true leaves); 5. 1 treatment: Phosphate-potassium chelate + Multimix gelatin + Mono boron gelatin (3-4 pairs of true leaves), 2 treatment: Mono boron gelatin (6-8 pairs of true leaves). The highest yield increase from the application of mineral fertilizers was obtained when fertilizing at a dose of N60P60K60 for all systems of basic tillage and is within: for classical – 0.52-0.64 t/ha; for landless – 0.40-0.51 t/ha; at the minimum – 0.35-0.45 t/ha. It should be noted that the cultivation of sunflower crops with growth stimulants in all their applications has led to an increase in yield: in the classical system of basic tillage by 0.13-0.32; for non-drained – 0.08-0.25 and for the minimum – 0.09-0.25 t/ha. The most effective under all other conditions of cultivation was the use of a mixture of preparations Growth-concentrate + gelatin oil. Indicators of economic efficiency of sunflower hybrid cultivation Ratnik, calculated at prices on 01.03.2021, varied depending on the options for the use of mineral fertilizers, growth regulators and methods of basic tillage. Taking into account the cost of the obtained products and the costs of its cultivation, the profit is obtained depending on the background of mineral nutrition and the application of growth regulators: 45156-57059 UAH/ha under the classic system of basic tillage with a profitability of 403-654 %; 41822-50349 UAH/ha for a bottomless system with a level of profitability of 358-616 %; 40699-48110 UAH/ha under the minimum system with a level of profitability of 359-642 %. The highest profit was obtained under the classical system of basic tillage, which exceeded this figure by 3334-7505 and 4457-9417 UAH/ha for bottomless and minimum systems. The most effective was the cultivation of sunflower hybrid Ratnik under the classical system of basic tillage against the background of mineral fertilizers at a dose of N40 and spraying crops in the phase of 6-8 pairs of true leaves with a mixture of Rost-concentrate + Helatin oil. The bioenergy efficiency of the studied agricultural methods varied depending on the options for the use of mineral fertilizers, growth regulators and methods of basic tillage. Taking into account the gross energy yield and total energy consumption for cultivation, the increase in gross energy was obtained, depending on the background of mineral nutrition and the variant of application of growth regulators: 45599-54678 MJ/ha under the classical system of basic tillage with energy coefficient 2.16-4.28; 42346-48528 MJ/ha for a bottomless system with an energy factor of 1.98-4.22; 40900-45998 MJ/ha for the minimum system with an energy factor of 1.92-4.18. The largest increase in gross energy was obtained in the classical system of basic tillage, which exceeded this figure by 3253-7048 and 4699-9216 MJ/ha in the bottomless and minimum systems. The most efficient in terms of energy indicators was the cultivation of sunflower hybrid Ratnik under the classical system of basic tillage against the background of mineral fertilizers at a dose of N40P60 and spraying crops in the phase of 6-8 pairs of true leaves with a mixture of Rost-concentrate + Chelatin oil.

Stability of Quantum Eigenstates and Collapse of Superposition of States in a Fluctuating Vacuum: The Madelung Hydrodynamic Approach

The paper investigates the quantum fluctuating dynamics by using the stochastic generalization of the Madelung quantum-hydrodynamic approach. By using the discrete approach, the path integral solution is derived in order to investigate how the final stationary configuration is obtained from the initial quantum superposition of states. The model shows that the quantum eigenstates remain stationary configurations with a very small perturbation of their mass density distribution and that any eigenstate, contributing to a quantum superposition of states, can be reached in the final stationary configuration. When the non-local quantum potential acquires a finite range of interaction, the work shows that the macroscopic coarse-grained description of the theory can lead to a really classical system. The minimum uncertainty attainable in the stochastic Madelung model is shown to be compatible with maximum speed of transmission of information and interactions. The theory shows that, in the quantum deterministic limit, the uncertainty relations of quantum mechanics are obtained. The connections with the decoherence theory and the Copenhagen interpretation of quantum mechanics are also discussed.

Relevansi Pemikiran Pendidikan KH. Imam Zarkasyi Dalam Pembentukan Intrapersonal Intelegensi

This article discusses about the relevance of KH Imam Zarkasi thoughts of education in developing intrapersonal intelligence. It is a kind of library research using descriptive-qualitative method. The resutt of this research shows that KH. Imam Zarkasi`s thoughts are still very relevant to be implemented in developing students` intrapersonal intelligence. Among of his thoughts are; 1) developing intrapersonal intelligence can be through two ways; intentionally, that is through education in formal institutions, and unintentionally that is through interaction with the surrounding community and the nature. 2) The method of learning to develop intrapersonal intelligence is through individual training; by entrusting children to carry out their own duties with full responsibility, giving children the opportunity to make their own decisions and be responsible for their decisions, and other similar activities. These thoughts have been applied by KH Imam Zarkasi through the institution he developed, namely Pondok Pesantren Gontor. Among of his renewal efforts are; The implementation learning using classical system, the use of learning methods that provide opportunities for children to develop their thinking power critically, independently and responsibly, and provide extracurricular activities as a forum for students to develop themselves.
