FORMATION AND USE OF ILLUSTRATIVE IMAGES IN THE “BIOETHICS AND QUESTIONS OF BIO SAFETY” COURSE
DescriptionIn this article, we describe the experience of formation and creating illustrative images for the course called «Bioethics and questions of bio safety». The peculiarity of this course is to review bioethical problems in the context of concrete scientific activities of the biologist – research, experimental work. The part of the course issues related to Bio safety, is revealed as an interdisciplinary area of knowledge focusing on the identification, study and understanding of biological practice and biological research associated with broad philosophical and moral component. The main blocks have been identified, which form visual resources: animals in the experiment, the questions of bioethics in the media; the metamorphosis of the human body; chimeras in works of art. In the selection of illustrative images we have taken into account several aspects: illustration, as an information resource for the analysis of the studied phenomenon; illustration, as a form of motivation to seek information, the answer to the question; illustration, as an element of ethical education of the student to different issues of bioethics. For each semantic unit collected 20-30 illustrative images within two years. They are used both when reading a lecture course and as material for independent work of students. It is shown that the presented visual resources for the course reflect the basic components of visual thinking: linear; structural; combinatorial and functional

MATHEMATICAL MODEL OF A DRYING PROCESS OF CORRUGATED CARDBOARD
DescriptionThe feature of the process of drying of corrugated cardboard is different drying processes on three sections of the drying table. The article solves the problem of obtaining a mathematical model of drying process of corrugated cardboard. This structural identification process, defined the input and output parameters, denoted the transmission coefficients for the control channels and indignation

THEORY OF ELECTROMAGNETIC DRIVE WITH ELEMENTARY PARTICLES CURRENT AND VACUUM POLARIZATION
01.00.00 Physical-mathematical sciences
DescriptionThe article discusses a model of rocket motor of electromagnetic type, consisting of a source of electromagnetic radio frequency oscillations and the conical cavity, in which electromagnetic waves are excited. We have created a multi-dimensional transient numerical model describing the process of establishing electromagnetic oscillations in the resonator, taking into account the finite conductivity of the walls. Separately, the standing waves in the cavity with conducting walls have been simulated. It is shown that the oscillations mode in the conducting resonator different from that in an ideal resonator, both in a case of steady and unsteady waves. We have built a dynamic model taking into account the thermal conductivity and electrical conductivity of the walls, waves and particles emission and vacuum polarization. We have also developed a dynamic model enables to optimize a thrust force on a considerable number of parameters without the involvement of the hypotheses about the physics of the phenomenon. We run the optimization of the operating parameters of the device, namely by the excitation frequency, the frequency of the modulating signal, the magnitude of heat losses of electromagnetic energy by thermal radiation in the IR spectrum, the parameters of forced heat transfer and the temperature dependence of the resistance of the material of the cavity walls. It is found that the pulse modulation greatly improves the efficiency of conversion of electromagnetic energy into thrust. The mechanism of formation of traction, adjusting the metrics of space-time, the current contribution of elementary particles, the Yang-Mills and electromagnetic fields is proposed. It is shown that the contribution of the elementary particles in the thrust force is proportional to the electrical conductivity of the system multiplied by Abraham force

USING MECHANISMS OF FORMALIZATION OF DIDACTIC CONTENT FOR SKILLS DEVELOPMENT MONITORING
DescriptionThe relevance of an effective system of professional development for science-intensive and high-tech industries demonstrates not only the need to promptly respond to the global challenges of the modern economy, but also the presence of professionals able to reform the Russian economy in conditions of adverse effects of the sanctions. The leading role in these processes is assigned to highly qualified staff, which is formed in the process of training specialists within the system of continuous professional education and training (CPEandT). Expansion of the use of the system of CPEandT in modern educational technology (MET) opens new possibilities for advanced training and monitoring of this process by formalizing mechanisms of didactic content. We have developed specific mechanisms of formalization of the bestknown relationship between the information flow of didactic content and scope of knowledge of professional disciplines plan of professional development, as well as the possibility of their use for the monitoring of the process. The article discloses mechanisms of formalization of the process of professional development for science-intensive and high-tech industries, which will actively contribute to their successful implementation and monitoring

NON-PARAMETRIC CYCLES ESTIMATORS
01.00.00 Physical-mathematical sciences
DescriptionIn many applications, we study the time series (or a random process), which is the sum of the periodic deterministic function of time and random errors that distort the periodic signal. It is required to estimate the length of the period and the periodic component. It does not assume that the periodic function is included in any parameter family of functions, such as finite sums of sines and cosines. It is obvious that the assumption of occurrence of a periodic function in parametric family does not meet the characteristics of the real world, ie, is conditional, internal mathematical (look for the keys under the lamp because there is a light, not in the bush, where lost, because there are dark). For similar reasons, it is impossible to assume that the distribution function of the random errors is included in any parameter family of distributions. In accordance with the new paradigm of mathematical statistics in this article we studied the problem of nonparametric estimation (minimum) length of the period and the periodic component of the signal. On the basis of natural variation and scope of indicators is suggested a new class of nonparametric estimators of the length of the period and the periodic component in the time series. Based on the general results of statistics of objects of non-numeric nature we proved the consistency of these estimates. From the practical point of view it is necessary to minimize the numerical (one parameter - ability length of period of time) one or more of the 66 functionals, described in the article

ROTARY SCREW SYSTEMS IN CEMENT
DescriptionThe article presents results of research of rotary-screw systems in relation to the creation of rotary kilns for the annealing of-cuttings in the preparation of cement clinker. Using the proposed design, in comparison with known designs of similar purpose, it significantly improves performance, reduces size and power consumption through the use of rotary screw systems in the form of screw rotors and drums made hollow with sidewalls assembled from separate strips or plates of different geometrical shapes with form inside the screw breaks or smooth edges, screw surfaces and screw grooves. It is shown that the housing of the rotary kiln is expedient to produce helical surfaces whose centers of curvature are located within the housing. Using the proposed constructions rotary kiln during the firing when preparing cement wedge can increase the speed of rotation of the housing, furnaces 5-10 times due to changes in the rotary-screw systems increase efficiency and reduce the size of furnaces
