Increasing the Competitiveness of Russian Agricultural Producers Using the “Economic Cross” Model

In this study, we proposed the directions of developing Russian agriculture by integrating innovative technological solutions (including digital ones) into the production-logistics chains of domestic producers. We identified economic-organizational constraints for the development of Russian agriculture and examined foreign and Russian experience in addressing similar issues on a systemic basis. Moreover, we examined the economics of the innovation process in Russian agriculture, taken in the context of the current geo-economic situation and the emerging factors (i.e., COVID-19, sanction wars, and the growing attention of the government to national security, especially food security). According to the results, we suggested several ways of adapting our “economic cross” model to the organizational-economic needs of the Russian agricultural producers. Additionally, we developed a system of recommendations for managing the life cycle of agricultural innovation using the “economic cross” model for the innovative development of sectors in various forecasted environments. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.

Experience of veno-venous extracorporeal membrane oxygenation in a pregnant woman with severe acute respiratory distress syndrome caused by the SARS-CoV-2 virus

Pregnant women occupy a special place in the incidence structure of the new coronavirus infection COVID -19. Taking into account the likelihood of a more severe course of acute respiratory syndrome (ARDS) in this group, it is worth remembering the possibility of timely use of veno-venous extracorporeal membrane oxygenation (IV ECMO) in order to correct life-threatening hypoxia. At the Lapino Clinical Hospital, a cesarean section was successfully performed in a 37-year-old female patient at 20–21 weeks of gestation against the background of IV ECMO with further decannulation and discharge from the hospital. © 2021 Sklifosovsky Research Institute for Emergency Medicine.

USING AIR EXCHANGE TO REDUCE THE PROBABILITY OF SPREADING CORONAVIRUS INFECTION

Statement of the problem. Ventilation processes have a significant impact on the spread of airborne infections. It is necessary to use air exchange to reduce the likelihood of spreading such infections. Mathematical model. Using the Wells - Riley model of airborne transmission of infectious diseases, a mathematical model has been developed for the spread of coronavirus infection in a medical institution, consisting of a group of communicating rooms in which both healthy and infected people are constantly located and moved. The mathematical model makes it possible to take into account the movement of people around the premises and the settling of quanta of the generation of infection by a sick person when air moves. Results. The general solution of the mathematical model is obtained, which allows calculating the concentration of quanta of generation of infection in the premises during the operation of a medical institution. Conclusions. The developed mathematical model of a medical institution allows a deeper understanding of the possibilities of the spread of coronavirus infection and taking these risks into account when designing medical institutions.
