July 19, Sergey Lavrov, Minister of Foreign Affairs of Russia awarded Ibrahim Naowaf, graduate of the Faculty of Philology of Peoples’ Friendship University of Russia, journalist of the International News Agency “Russia Today” with the Badge “For Interaction” of the Ministry of Foreign Affairs of the Russian Federationю.

July 16, Oleg Yastrebov, RUDN University Rector and Riad Haddad, Ambassador of the Syrian Arab Republic to Russia held talks. During the meeting, they discussed the study of Syrian students at RUDN University and validation of Russian diplomas. RUDN University Rector assured the meeting participants that the issue of diploma validation would be resolved in the near future.

RUDN University biologist studied the aggressive impact of environmental factors (water, salts, and ozone) on ultrathin nanofibers of biopolymers. The results will help choosing suitable bioplastic depending on the use; for example, for medical implants, biodegradable packaging or filters for water cleaning.

RUDN University mathematicians built a model of COVID-19 spreading based on two regression models. The mathematicians divided the countries into three groups, depending on the spreading rate and on the climatic conditions, and found a suitable mathematical approximation for each of them. Based on the model, the mathematicians predicted the subsequent waves. The forecast was accurate in countries where mass vaccination was not introduced.

Soil scientists from RUDN University confirmed that traditional approaches to monitoring of urban soil pollution ignore actual risks for urban residents because they don’t take into consideration the barrier function of the soil. The team used Moscow as an example to show that not only polluted downtown districts but also recreational parks and forest zones can pose a threat to people. This is due to the fact that the barrier functions of the soil are weaker in green suburbs, making it unable to withstand even the slightest pollution.

A scientist from RUDN University analysed the effect of visual impairment on a person’s perception of unfamiliar sounds when learning a foreign language. The experiment showed that lack of access to visual cues makes learning difficult.

According to a linguist from RUDN University, the number of COVID-19 cases in a country correlates with the number of aspirated consonants in its main language of communication. This data can help create more accurate models to describe the spread of COVID-19.
