Description
This article presents the results of a study of new me-dium-ripe lines obtained using the donor line Kl7427 for reduced grain harvesting moisture. According to the results of this study, the lines recommended as a starting material for the selection of lines and hybrids of maize of the middle group of ripeness with low grain moisture at the time of harvesting without signif-icant loss of productivity were identified

Description
The work is devoted to studying the nature of the influence of individual abiotic factors of the southern territories of Russia on the features of the formation of an economic apple yield in adjacent years and the justification of the possibility of adjusting the course of this process in adverse environmental conditions. The studies were carried out in 2018-2019, which are distinguished by the manifestation of weather anomalies in the summer-autumn period. Field experiments were performed at the farms of the Kuban horticultural zone on soils suitable for planting fruit stands: leached and typical chernozems. The features of the development of plants of apple trees of winter varieties Kuban crimson and Fuji on the stock M9 were studied. In the experiments, an option is provided using foliar treatment of plants with Pomaset fertilizer. The effectiveness of the formation of the economic apple crop depends on the biological characteristics of the used pomological variety, as well as the temperature and moisture conditions during the growing season of the plants. Soil conditions do not significantly affect the course of this process. The probability of losing the potential apple crop at the XII stage of organogenesis (pre-harvest decay) under the influence of abiotic summer stressors: high air temperatures and water deficiency is noted. With the manifestation of extremely high air temperatures in late summer and during the autumn months, a significant increase in the duration of vegetation of various (especially strong-growing) apple varieties was recorded, causing a shift in the process of differentiation of generative buds (stages III-IV of organogenesis) to a later date, and, as a result, - decrease in potential plant productivity in the next season. With the manifestation of abnormal weather conditions, the prospects of foliar treatment of trees in the second half of the growing season with Pomaset fertilizer, which optimizes the fruiting of the apple tree in adjacent years, are shown. At the same time, the fruit yield in the current year is increasing by 9-14%, and in the next season - by 7-10% in comparison with the control values

INFLUENCE OF BASIC TREATMENT ON AGROPHYSICAL SOIL PROPERTIES IN CROPS OF WINTER BARLEY
DescriptionThe article presents the results of studies on the influence of the main tillage in the technology of cultivating winter barley on its agrophysical properties. The object of research was winter barley, sort Rubezh, the predecessor - winter wheat. Soil - heavy duty, low humus, typical leached chernozems. The studies were carried out in a stationary experiment on the basis of the experimental field of the Department of General and Irrigated Agriculture at KubSAU in accordance with generally accepted methods for experiments with grain crops. Scheme of experience (primary tillage): option 1 (A0) - dump plowing to a depth of 20-22 cm (control); option 2 (A1) - chisel for 20-22 cm; option 3 (A2) - disk peeling at 8-10 cm; option 4 (A3) - zero treatment (direct sowing). Based on the research, a general orientation is revealed in the technology of cultivating winter barley to reduce the agrophysical indicators of the soil throughout the growing season of the development of its plants while lowering the tension of its main processing. So, the density of the soil was minimal, and the structure and moisture of the soil, as well as the reserves of productive moisture were maximum on the option with dump plowing to a depth of 20-22 cm. Conducting deep loosening at the same depth (chiseling by 20-22 cm) somewhat worsened these parameters . Implementation of disk peeling in the main tillage (by 8-10 cm) contributed to the deterioration of these parameters. The option of zero tillage was in last place according to these indicators. And only before harvesting, zero tillage contributed to the formation of higher soil moisture and productive moisture reserves

DescriptionIn the process of formation of nonlinear dynamics, the scientific society was able to refute the classical mechanisms of Newton-Laplace by justifying the chaotic nature of the phenomena of the world. However, despite the emergence of new mathematical models and tools, forecasting of nonlinear systems is a difficult task, as not only the quantitative and qualitative characteristics of the factors affecting the system are unknown, but also there is a problem of a small amount of information for forecasting. In this article, the authors consider the linear cellular apparatus as a tool for prediction the final state, to which the system will come based only on its output indicators of previous years. Since the use of a linear cellular automaton for prediction of nonlinear systems is an assumption of the authors, it should be tested on the series of stochastic systems exposed to different risk factors, which together give either a positive response of the system or a negative one. An example of such series is the time series of yields, as it is affected by climatic conditions, the appearance of which, in turn, is also difficult to predict. Prediction of stochastic systems using linear cellular automaton really makes it possible to get adequate and visual models. Due to the fact that the forecast model has a discrepancy with the real result of 0-15% (both positive and negative), the conclusion is that the predicted value will help either to take measures to ensure that the real value in the future is not lower, or to make sure that the decisions and measures taken are correct, when a value is higher than the forecast

DescriptionThe article discusses modern approaches to the implementation of the migration of virtual machines between different virtualization platforms. A comparative characteristic of virtual migration tools is given. Conclusions are drawn on the expediency of applying different approaches depending on the task facing migration and available resources. The author presents a technique for migrating virtual machines from VMware vSphere virtualization platform to Microsoft Hyper-V virtualization platform, which allows to increase the speed and reliability of the migration process and significantly save on operating costs of the company

DescriptionAt present, the problems of blocking network traffic in computer networks, in particular, in the global Internet, are becoming increasingly topical. Understanding blocking mechanisms, opening new opportunities to circumvent such protection will give us, on the one hand, both new methods and methods of protection against unwanted blockages, and the vector of development of funds, in fact, stopping unwanted traffic, obstacles passing through network nodes. The article proposes an approach to effectively bypass access restrictions to websites based on HTTP tunneling with minimal costs, combined with the approach used in peer-to-peer networks. A description of the algorithm and its key features. A new approach has been introduced in the task of ensuring the accessibility of websites, which has several advantages and eliminates the disadvantages of existing solutions in the form of anonymous networks - the use of special node solutions and a strong dependence on the number of nodes in the anonymous network. The level of development of modern network infrastructure, the transition of society and most of human civilization to the information-network existence dictates new requirements for technical means of monitoring and analyzing network traffic. That, in turn, requires the development of new approaches to solving relevant problems
