The study of the nature of variations in cosmic ray fluxes, including diurnal, 27-day, annual, etc., and the question of the relationship of solar-geophysical factors on the state of the atmosphere attracts special attention of scientists. Coronal mass ejections are the result of solar winds generated on the Sun during a series of flares. At the same time, solar winds provoke variations in the intensity of cosmic rays, which include, in particular, Forbush-decreases. The article presents brief characteristics of the CARPET detector of the scientific cosmophysical complex of the L.N.Gumilyov ENU and experimental data obtained at this facility during the observation of Forbush-deacreases in July and September 2017. The results of the analysis of variations in cosmic ray fluxes are presented and their relationship with the conditions in the interplanetary medium and the Earth’s magnetosphere caused by processes on the Sun is described. It was found that the decrease in cosmic ray fluxes in July and September 2017 was due to high solar activity (a series of solar flares). A comparative analysis of the time changes recorded by the CARPET detector modules of the L.N.Gumilyov ENU scientific complex with the data of the world network of neutron monitors («Apatity», «Almaty» and «Jungfraujoch IGY») is also presented. Data on the electromagnetic environment of interplanetary space during the period of heliospheric and magnetospheric disturbances were also used for the analysis. The analysis showed that the measurement data of the CARPET detector is in good agreement with the data of the above-mentioned neutron monitors of the world network, which allows us to study the physical nature of cosmic ray variations for different time intervals.

The technological advances of the last 15 years have made a huge contribution to modern society, transforming education and training. Computers and the Internet allow teachers and students to work, learn, and receive information in ways that were once unthinkable. One of the latest and yet most exciting technological developments in education is the use of virtual reality (VR) and augmented reality (AR) to enhance learning opportunities. Virtual reality and augmented reality allow users to interact with computer environments, real or imagined. VR also allows users to receive visual, auditory, tactile, smell, and taste inputs in three-dimensional space.As a result, the authors implemented a virtual laboratory with the possibility of conducting a virtual experiment, which includes practical and theoretical tasks in high school physics, as well as a set of animations. When developing the virtual electronic laboratory, agile software development methodologies, computer modeling methods, and object-oriented programming were used. As a virtual reality device, the Leap Motion motion controller was chosen, designed to track the movements of hands and fingers in space and used for human-computer interaction. The article provides UML activity diagrams for working and interacting with the application. The cross-platform Unity 3D environment, which implements the WORA (write once, run anywhere) principle, was chosen as the development platform. Thanks to this principle, a once-written application can be built for personal computers, mobile devices, mixed reality helmets, and many other platforms. The application functionality was written in the C# programming language. Graphic models were created using Substance Painter. The developed application can be used by students of senior classes of secondary and specialized schools, students of technical majors of higher educational institutions, as well as any interested users.

This work is devoted to the study of various morphological features of LixTi1-xO3 ceramics obtained by solid-phase synthesis and subsequent thermal annealing. Interest in these ceramics is due to the great potential for their use as materials for breeders or blankets for tritium reproduction. The choice of synthesis technology is due to the wide possibilities of changing morphological features and elemental composition, due to mixing of various components in different stoichiometric ratios. During the research, it was found that for lithium-containing ceramics, thermal annealing at a temperature of 800°C leads to the following changes: for ceramics with a lithium content of X=0.1-0.2, a change in shape is observed from rhomboid and cubic to diamond-like and hexahedral, with a sharp increase in grain sizes, which is associated with sintering processes. An increase in lithium concentration in the ceramic structure of X=0.3 leads to the formation of large grains, the size of which varies from 300 nm to 500 nm. Keywords: lithium-containing ceramics, solid-phase synthesis, titanium dioxide, agglomerates, thermal annealing
