Mathematical modelling of process of salt transfer under filtration and moisture transfer in saturated and non-saturated soil mass with available mobile free surface

Здійснено математичне моделювання процесу солепереносу при сумісній фільтрації підземних вод та вологопереносі в насичено-ненасиченому ґрунтовому середовищі. Розглянуто задачу безнапірної стаціонарної фільтрації сольових розчинів за наявності рухомої вільної поверхні ґрунтових вод, яка задана на межі областей повного та неповного насичення. Вважається, що сольові розчини находять у ґрунтове середовище з поверхні області неповного насичення і вимиваються через дрену (осушувальний режим). На основі побудованої математичної моделі даної крайової задачі проведено дослідження процесу солепереносу до дрени в області повного насичення та процесу вологопереносу з урахуванням солепереносу в області неповного насичення ґрунту; досліджено протікання даних процесів сумісно для обох областей водонасичення. Чисельні розв’язки відповідних крайових задач знайдено методом скінченних різниць із використанням чисельних конформних відображень. На основі програмної реалізації задачі проведено чисельні експерименти та здійснено їх аналіз.The mathematical modelling of the process of salt transfer under joint filtration of ground waters and moisture transfer in saturated-non-saturated soil medium has been carried out. The problem of the free flow stationary filtration of salt solutions under the available mobile free surface of ground waters which is set at the boundary of areas of complete and incomplete saturation has been considered. It is believed that salt solutions enter soil medium from the surface of incomplete saturation and are washed out via drain, i.e. the problem of salt transfer is considered in the case of drainage regime. On the basis of the built mathematical model of this boundary problem the research of the process of salt transfer to the drain in the area of complete saturation and of the process of moisture transfer taking into account salt transfer in the area of incomplete soil saturation has been conducted. The comprehensive study of the process of salt transfer in areas of complete and incomplete saturation is carried out. For this purpose these areas of water saturation are considered as one entity with common unknown boundary which is in the process of problem solution. It makes possible to find the interconnection between investigated processes and to carry out their prediction in the area of saturated-non-saturated soil medium. On the basis of the comprehensive solution of the problem the change of free surface under the influence of processes studied has been established. Numerical solutions of relevant boundary problems are determined by the method of finite differences using numerical conformal mapping. On the basis of programmed implementation of the problem the construction of the conformal mapping in areas of filtration flow, moisture flow and conformal differential network of the area of saturated-non-saturated soil medium has been done; there have been received numerical results and graphical representation of the distribution of the field of piezometric pressure heads, of moisture pressure heads and of concentration of salts in areas of complete and incomplete saturation and also of the distribution of the field of salt solutions concentration in saturated-non-saturated soil mass. A number of numerical experiments has been conducted which gave the possibility to carry out the analysis of results obtained with different initial data of the problem and to research in detail the nature of the action of the process of salt transfer under filtration and of moisture transfer in saturated-non-saturated soil medium

Self-actualization and subjectivity in young men looking for a new job

The study subject is self-actualization and subjectivity in men looking for work. The purpose of this research is to identify the features of their self-actualization and subjectivity. Such methods of psychodiagnostics as the “SAT” technique by E. Shostrom (adapted by Yu.E. Aleshina et al.); the “URSL” test by M.A. Shchukina were used. Taking into account the main results of the study, the author came to the conclusion that the sample as a whole revealed problematic self-actualization and a fairly high overall level of subjectivity. In 83% of respondents, self-actualization was revealed only by contact. The proportion of men who recognize the values of a self-actualizing personality was 34%. A direct close connection between self-actualization and subjectivity has been established. The field of application of the found results is the social psychology of personality (the data received are important for assessing the socio-psychological readiness of men to promptly solve the problem of employment using intrapersonal resources). Mentioning the prospects of the study, it should be advisable to perform a comparative analysis of data by gender. The results obtained are valuable for practical social psychologists in terms of helping young men who find it difficult to realize their intentions to find a new job due to problematic self-actualization and insufficient subjectivity

Self-actualization and subjectiveness in young men and women looking for a new job

The subject of the research is self–actualization and subjectiveness of men and women looking for a job, and the goal is to identify differences. The article uses the method of psychological testing, i.e. J.E. Aleshina’s adaptation of E.L. Shostrom’s SAT test and M.A. Shchukina’s LPSD test. As a result of the study, both groups have revealed developed subjectiveness and a minimum of signs of self-actualization. In the group of men the indicator of orientation in time corresponds to the level of personality disorders, in the women one it is normative, with more developed self-support. Signs of self-actualization in men are marked only by contact, in women – by contact, acceptance of aggression, and flexibility of behavior. The share of self-actualizing men is 13 %, of women is about 22 %. Men have a higher level of subjectiveness, in the structure of which creativity dominates, and women have integrity. The field of application of the results obtained is applied and practical social psychology, and psychology of employment services. Prospects of the study conclude development of self-actualization programs for young people in search for a new job. The article concludes young men and women with work experience looking for a new place of employment emphasize their subjectiveness and do not hurry to include self-actualization mechanisms to become more competitive
