FORMATION OF EXPERIENCE AGAINST THE CHALLENGES OF VIRAL INFECTION THROUGH THE USE OF STUDENTS KNOWLEDGE OF BIOSAFY TECHNOLOGIES, part 2

New challenges and the state of development of COVID-19 in connection with the spread of new strains of SARS-CoV-2 have been analyzed. Experience and knowledge in working with new means of protection of different types of vaccines are studied: both classic, based on inactivated virus or its fragment, and the new generation – with vector and genetic mRNA vaccines, as well as effective antiviral drugs. Biorisks and compliance with biosafety principles have been studied.

Modeling of the COVID-19 pandemic in the limit of no acquired immunity

We propose the SEIRS compartmental epidemiology model aimed at modeling the COVID-19 pandemy dynamics.  The limit case of no acquired immunity (neither natural nor via vaccination) is considered mimicking the situation (i) when no effective vaccine being developed or available yet, and (ii) the virus strongly mutates causing massive reinfections.  Therefore, the only means of suppressing the virus spread are via quarantine measures and effective identification and isolation of infected individuals.  We found both the disease-free and the endemic fixed points and examined their stab

Fractional-order mathematical model for analysing impact of quarantine on transmission of COVID-19 in India

An outbreak of the novel coronavirus disease was first reported in Wuhan, China in December 2019.  In India, the first case was reported on January 30, 2020 on a person with a travel history to an affected country.  Considering the fact of a heavily populated and diversified country like India, we have proposed a novel fractional-order mathematical model to elicit the transmission dynamics of the coronavirus disease (COVID-19) and the control strategy for India.  The classical SEIR model is employed in three compartments, namely: quarantined immigrated population, non-quarantined asymptomat

Administrative and legal measures to prevent the spread of the COVID-19 pandemic: the case of Ukraine, the Russian Federation and the Republic of Belarus

Attempts to analyse measures taken by the governments of Ukraine, the Russian Federation and the Republic of Belarus in struggle against the COVID-19 pandemic are made. Some issues of the current legislation, which were introduced under new circumstances in above-mentioned states are raised in the article. Most countries of the world were not ready for the changes in the objective legal reality which should have occurred in view of the need to combat the pandemic. The existing legal framework has not been sufficient to respond quickly to the challenges posed by the COVID-19 infection.

Biomedical Cyber-physical System for Round-the-clock Monitoring of Lung Functions in Patients With COVID-19.

The coronavirus has the greatest effect on the lungs. That is why the lungs of patients with COVID-19 need constant medical monitoring. The paper considers the biomedical cyber-physical system for round-the-clock monitoring of lung functions in patients with COVID-19, which allows physicians to continuously monitor the main organ of patients affected by the coronavirus — the lungs. It is designed to monitor the patient’s condition around the clock and regardless of the patient’s location.

Investigation of Wireless Pulse Oximeters for Smartphone-based Remote Monitoring of Lung Health

Coronavirus has the greatest effect on the human lungs. This is why lungs of patients with COVID- 19 require constant medical monitoring. One of the tools for the lungs condition monitoring is based on the wireless pulse oximeters connected to smartphones. There is an attempt to analyze the types of pulse oximeters, their technical characteristics, principles of operation and basic requirements for these measuring instruments in the article. According to this study, the most effective pulse oximeters for 24/7 monitoring of lung function were selected.

Impact of COVID-19 on Rail Freight Market

The COVID-19 pandemic has changed not only the lives of many people, but also the situation in global and local markets. Worldwide, there has been a significant reduction in production capacity due to the closure of borders between countries and the introduction of self-isolation. The spread of the epidemic disrupted the usual trade relations between producers and consumers, caused serious changes in the activities of logistics companies.

URBAN PUBLIC TRANSPORT POLICY IN THE CONDITIONS OF COVID-19

The purpose of the research is formation of passenger transport policy by public transport from the standpoint of determining the level of safety in COVID-19 and passenger comfort with the development of basics for measuring the perception of the most important factors of public transport convenience, minimum discomfort and maximum safety. Methodology. The study was conducted in two stages - inhouse and experimental - the collection and processing of data obtained from the survey of passenger flows.
