The article introduces one of the ways to form students' practical skills by solving experimental problems focused on a specific practical method that can be successfully used to solve life's cognitive problems. The introduction of the proposed approach was preceded by the study of the opinions of physics teachers of secondary schools in the Volyn region of Ukraine. The attitude and wishes of students from the same region to solving experimental problems are clarified. The definition of experimental problems is offered as follows: these are the problems with the data taken from the experiment to obtain a solution. The solution of experimental problems is considered as a part of educational physical experiment, which is an essential component of the methodical system of teaching physics, as it provides the formation of the necessary practical and research skills. A series of experimental problems that provide the formation of practical skills of students on the example of educational material devoted to the study of the concept of "density of matter". A solution is proposed for each problem. The views of scientists on the problem of using experimental problems in the practice of physics lessons are reflected; the difficulties that teachers face when using the mentioned type of tasks are outlined. A study of corresponding textbooks in recent years on the problem of using experimental problems in the practice of teaching students is conducted. Methodical recommendations on the choice of time for solving the given series of experimental problems, forms of work of students in a modern physics lesson are offered. Attention is paid to the selection and solution of experimental problems of other educational material related to the concept of "density of matter", the place and forms of their solution in the practice of the lesson are substantiated. The effectiveness of the proposed approach to solving experimental problems on the basis of expert evaluation is established.

The rapid development of innovative technologies is based on the integration of natural sciences. The development of new branches of science such as synergetic, cybernetics, the noosphere, etc. is the result of the integration of the sciences. One of the requirements for the updated educational program, which is introduced in Kazakhstan, is the continuity of disciplines, the definition of interdisciplinary relations in the short term of each lesson and its implementation in the classroom. Since Physics is the fundamental base of natural science, increasing students’ interest in Physics through its interaction with other disciplines will ensure the fulfillment of the requirements of the new program in the field of education. This article proposes the content of a number of lessons used in teaching Physics for effective solution of problems related to the practical creativity of the process of developing students’ cognitive interests.

Abstract In this paper, we present a new definition of interval-valued convex functions depending on the given function which is called “interval-valued approximately h-convex functions”. We establish some inequalities of Hermite–Hadamard type for a newly defined class of functions by using generalized fractional integrals. Our new inequalities are the extensions of previously obtained results like (D.F. Zhao et al. in J. Inequal. Appl. 2018(1):302, 2018 and H. Budak et al. in Proc. Am. Math. Soc., 2019). We also discussed some special cases from our main results.

How many fractals exist in nature or the virtual world? In this paper, we partially answer the second question using Mandelbrot’s fundamental definition of fractals and their quantities of the Hausdorff dimension and Lebesgue measure. We prove the existence of aleph-two of virtual fractals with a Hausdorff dimension of a bi-variate function of them and the given Lebesgue measure. The question remains unanswered for other fractal dimensions.

Recent research about the theoretical approach to elements of cultural heritage that can be included in the newly born class Underground Built Heritage (UBH), has provided several instruments for the functional classification and the static and dynamic analysis of all artefacts coherent with the given definition, while introducing several criteria for their reuse and the evaluation of connected enhancement processes as well. These guidelines can be adopted to analyze single artefacts, groups of homogenous or heterogeneous elements, and also selected territorial assets or national systems, even at a comparative level. With reference to this potential, research results from the application of this new methodological approach to the outputs of three ongoing projects by the National Research Council of Italy, all focusing on UBH, in three countries: China, Japan and Italy, are presented. With reference to the above-mentioned geographical contests, the research introduces a comparative study focusing on selected examples of artefacts that have been historically built underground to manage three functions: living space, religion and economy. This study, carried out based on data collected during onsite visits by the authors, consists in three steps: selection and analysis of case studies, definition of level of reuses on the basis of a given scale, and analysis of the different tools adopted for their conservation and enhancement. In the conclusions, possible future implementations of reuses of the analyzed elements are pointed out.

The training of future doctors should be continuous and organized at a high level, because medicine is one of the priority spheres of society. With the introduction of quarantine in the context of a pandemic, the question of changing the format of classes has become especially acute, which is associated with the need to exclude massive concentrations of medical students. In our academy, in the first days of quarantine, communication was organized by groups in the Viber and Telegram messengers. In the following days, training was carried out on the use of the Zоm service platform for video conferencing, online meetings and distance learning, and trainings were organized. The department’s website contained the contact information of all teachers, the schedule of classes, the thematic plan of lectures and practical classes, a list of basic and additional literature for students of each course. In the materials for downloading, students had the opportunity to familiarize themselves with multimedia presentations of lectures, teaching aids developed by the staff of the department, methodological recommendations on all topics of practical exercises according to the thematic plan. It should be noted that new educational technologies contribute to the improvement of information competence, allow students to independently master the educational material, but training a doctor in practical skills requires the student’s traditional face-to-face contact with teachers and patients.

The purpose of this work is the assessment and forecasting of freight car technical state at life stages. The scientific novelty consists in the definition of car operating run-up to the first failure and between failures, and also in the definition of car life to considerable repair fulfillment from the operating run between failures and development of a graphical model of freight car reliability. As a result of the statistic modeling of gondola car operating runs up to the first failure it is defined that the given random value conforms to a normal distribution law, the first car setoff in TOR due to wear failure takes place at the operating run of 85,000 km. Besides the operating run-up to the first failure there was defined an operating run-up between failures. It is proved that the operating run-up between failures conforms to the exponential law of distribution, the mathematical expectation of which is 13,000 km. The results of investigations mentioned above formed the basis of the graphical model of car reliability. An inter-repair service life of a car can be represented as a sum of the following operating run-ups: operating run-ups to the first failure, the product of operating run-ups between failures and the number of failures and a residual operating run-up (from the utmost current repair to the nearest scheduled repair). On the basis of the mentioned it is expedient to consider a technology for the realization of an enlarged repair with the purpose of the repetition exclusion in car setoffs during the inter-repair term. On the basis of the simulator there is obtained the dependence of the frequency of car enlarged current repair fulfillment depending on average operating run-up between failures. At present an enlarged current repair must be carried out only for gondola cars in the planned order after having reached 80,000 km. The repair mentioned can be carried out both under depot conditions, and under conditions of repair workshops. The advantage of such a system of repair consists in the increase car work reliability during the inter-repair term.

Fractals play a central role in several areas of modern physics and mathematics. In the present work we explore resistive circuits where the individual resistors are arranged in fractal-like patterns. These circuits have some of the characteristics typically found in geometric fractals, namely self-similarity and scale invariance. Considering resistive circuits as graphs, we propose a definition of self-similar circuits which mimics a self-similar fractal. General properties of the resistive circuits generated by this approach are investigated, and interesting examples are commented in detail. Specifically, we consider self-similar resistive series, tree-like resistive networks and Sierpinski’s configurations with resistors.
