We study the effect of a low-molecular fraction (below 10 kDa) derived from human cord blood and Actovegin on the content of various forms of hemoglobin in erythrocytes stored under hypothermia (2-4 ºС) for 21 days. During the long-term storage of erythrocytes, there is known to be a change in the hemoglobin forms ratio toward the decrease of the relative content of oxyhemoglobin and an increase of deoxy- and methemoglobin. As a result, the affinity of hemoglobin for oxygen reduces. The incubation of erythrocytes in a rehabilitation medium with each of the studied low-molecular drugs was found to be crucial to increase the content of oxyhemoglobin and to reduce the amounts of deoxy- and methemoglobin relative to the control. As a result, there was a rise in the oxygenation coefficient, reflecting the oxygen saturation of hemoglobin, up to the level characteristic of freshly isolated erythrocytes. The data obtained show that the human cord blood low-molecular fraction and the Actovegin normalize the ratio of hemoglobin forms in hypothermically stored erythrocytes, but the use of the Actovegin drug is more effective.

The article presents the results of evaluating the protein complex of wheat from different growing areas, stored in the silos of elevators for 6 years. It is shown that the protein content and quantity and quality of gluten changes slightly during long-term storage; the main fraction of wheat protein substances is a low molecular fraction up to 3 kD. There were no changes in the milling and baking characteristics of wheat for the period of 4-6 years of storage.

A model of moisture movement in wood is presented in this paper in a two-dimensional-in-space formulation. The finite-difference technique has been used in order to obtain the solution of the problem. The model was applied to predict the moisture content in sawn boards from pine during long term storage under outdoor climatic conditions. The satisfactory agreement between the numerical solution and experimental data was obtained.

The introduction and active use of information transmission and storage systems in the Ministry of Defense (MoD) of Ukraine form the need to develop ways of guaranteed removal of data from media after their use or long-term storage. Such a task is an essential component of the functioning of any information security system. The article analyzes the problems of guaranteed destruction of information on magnetic media. An overview of approaches to the guaranteed destruction of information on magnetic media of different types is presented, and partial estimates of the effectiveness of their application are given by some generally accepted indicators of performance evaluation. The article also describes the classification of methods of destruction of information depending on the influence on its medium. The results of the analysis revealed the main problems of application of software methods and methods of demagnetization of the information carrier. The issue of guaranteed destruction of information from modern SSD devices, which are actively used in the formation of new systems of information accumulation and processing, became particularly relevant in the article. In today's conditions of development of the Armed Forces of Ukraine, methods of mechanical and thermal destruction are more commonly used today. In the medium term, the vector of the use of information elimination methods will change towards the methods of physical impact by the pulsed magnetic field and the software methods that allow to store the information storage device, but this today requires specialists to develop new ways of protecting information in order to avoid its leakage.
