One of the most important areas of development of the agro-industrial complex at the present stage is obtaining high and sustainable grain yields. Spring triticale plays a significant role in solving this problem, as one of the most productive grain crops. In this case, adjusting the seeding rate is an affordable and effective method for successfully managing the crop's productivity. The purpose of the study is to substantiate the optimal sowing dates and seeding rates of spring triticale in the zone of ordinary chernozems of Northern Kazakhstan, providing a maximum yield of grain products. The innovation of this article is that it presents data on the study of sowing dates and seeding rates of nontraditional spring triticale culture of two varieties -Dauren and Rossika in the conditions of the North Kazakhstan region. The results of the average yield of spring triticale varieties depending on the sowing period, seeding rates, and meteorological indicators of the growing season of 2019-2021 were provided. It was concluded that the most optimal sowing period is the end of the second ten daysthe third ten days of May, and the optimal seeding rate is in the range of 4.0-5.0 million germinable seeds per hectare.

Study of aircraft aerodynamic characteristics with operation of its powerplant engines is a vital task. In this article we represent mathematical modeling of the aircraft flow with operation of its propeller. The considered mathematical model of the propeller is based on the vortex and momentum theory. Solution of the model problem of the flow behind the propeller allows obtaining of the fields of perturbed velocities in the vicinity of the aircraft and its aerodynamic characteristics. The proposed approach is aimed at simplification of the mathematical model and reduction of calculation time.

Since Descartes “separation” of the Soul from the Body, we observe a complete confusion in their causal, functional, and semiotic relationships. However, in modern knowledge (about the informational activity of the human brain, the functional and causal properties of its neural networks, the functions of psychic phenomena during the processing of information in it, about the causal “ability” of information) it is time to put an end to this problem. Here, in order to explain what I am talking about, I will use the notion of “information” (which had been unknown by Descartes) regarding the “dispute” between Mind & Body (the Physicality and the Mentality) for “the right” to be a more fundamental ontology of Reality. I will do this by introducing an “arbitrator” — the Objective Reality. This goal is achieved through the study of information activity of the human brain. In the process of this study, it turns out that the information activity of the brain in principle cannot be carried out without mental phenomena. That is, it turns out that the classical physical causality, which operates in the neural networks of the brain, is not able, by itself, without mental phenomena, to implement the information operations that the human brain actually performs. It also turns out that the functional inclusion of mental phenomena (at least, the phenomena of subjective evaluation and mental images) in the neurophysiologic (by and large, physical) activity of the brain explains the possibility and necessity of functional inclusion in this information processing the phenomenon of freedom of choice. After all, the processing information in the brain through mental phenomena allows more than one degree of freedom than it is “allowed” by any physical process.

In this article we consider one of the approaches aimed at reducing time of calculation of aerodynamic characteristics of the studied objects using discrete vortex method. Also, accuracy assessment of calculation of aerodynamic characteristics was performed.Analysis of the obtained dependences allows us to make a conclusion that the considered approach to the calculation of the functions of the mutual influence on the stages of formation of the system of linear algebraic equations, position of vortex sheet nodes as well as aerodynamic loads reduces hardware costs about three times, with a relative error of less than 4%.
