RUDN specialists become participants of Marcel Grossman Meeting (MG15)
July 1 - 7, 2018, one of the oldest and most prestigious universities - University of Rome "La Sapienza" (Rome, Italy) hosts the Marcel Grossman Meeting (MG15), International Conference on Recent Developments in Theoretical and Experimental General Relativity, Astrophysics and Relativistic Field Theories, the largest world platform, uniting scientists every three years in different cities of the world. In 2018, more than 900 specialists in theoretical physics take part in the conference, including Nobel laureates - Gerard 't Hooft and Steven Weinberg.
The program of the event included more than 40 plenary reports and 72 thematic sections - the whole spectrum of fundamental and experimental research in the fields of gravity, cosmology, astrophysics and field theory. Experts of RUDN Center for Gravitation, Cosmology, Astrophysics and Space Systems delivered reports: “Dynamic wormholes from nonlinear electrodynamics in GR” (K.Bronnikov), “Stabilization Of Extra Dimensions In Nonlinear Multidimensional Gravity With Multiple Factor Spaces” (S.Bolokhov) and “Can a Kerr black hole be a supercollider?” (M.Skvortsova).
A team of medics from RUDN University conducted an experiment on rats and confirmed that surgeries in the nasal cavity can cause behavioral changes, namely, make the animals timider. This effect is associated with an ANS reaction triggered by stress.
Bacteria in biofilms are 1,000 times more resistant to antibiotics, disinfectants, mechanical treatment, and other types of stress. A chemist from RUDN University suggested a method to prevent the formation of biofilms and reduce the resistance of bacteria to antimicrobial medications. This might help increase the efficiency of antibacterial treatment in the food industry, medicine, and agriculture.
A specialist in spacecraft movement control analyzed the process of placing vehicle stages, boosters, and other space debris into the so-called disposal orbit and suggested cleaning lower orbits up with a spacecraft that has modules with engine units on board. These modules will attach to space debris objects and move them away. As for the geostationary orbit, a preferable way to clean it up would be a towing spacecraft that transports space debris objects into the disposal orbit.
