Scientific work with RUDN mathematicians was led by Professor Dmitry Efrosinin from Johannes Kepler University. The main area of research is fifth-generation 5G network technology. In particular, the objects were Enhanced Mobile Broadband and Ultra-Reliable Low-Latency Communication. For correct formulation of the problems, RUDN University and Johannes Kepler University scientists studied joint transfer of information using eMBB and URLLC technologies, analyzed the queuing system and its application within the framework of Licensed Shared Access, and also performed an algorithmic analysis of a two-class multiserver heterogeneous system queuing with controlled cross-connection.
The internship lasted a week, but the collaboration between the research teams of RUDN University and Johannes Kepler University will continue. The team of young mathematicians at RUDN University outlined promising topics for joint study.
A chemist from RUDN University has developed a catalyst for the production of eugenol acetate, a substance that destroys the larvae of mosquitoes transmitting dangerous diseases, being a safe chemical for human health.
RUDN soil scientists have revealed a direct correlation between the rate of soil formation of carbon dioxide, called CO2 emissions, and the content of microbial biomass in it. It is known that CO2 emission from soil is mainly conditioned by respiration of soil microorganisms and plant roots. The more CO2 soil emits, the more microbial biomass it usually contains. It was shown that CO2 emission by chernozem of different ecosystems (or different types of land use) correlates with the content of microbial biomass, and most closely with the rate of its microbial respiration. And the soil with good microbial properties has the “best quality”, is more fertile, provides the highest yield of crops and other plant biomass.
A RUDN chemist has synthesized a catalyst for the production of gamma-valerolactone — an energy-intensive “green” biofuel. The catalyst based on zirconium dioxide and zeolite has shown high efficiency in converting the waste of wood plant materials — methyl levulinate — to gamma-valerolactone.
