Device for regulating the composition of the combustible mixture supplied by the carburetor

(Oschepkov P. P., Kamyshnikov R.O., Mirolyubov V. I., Novikov V.A., Kamyshnikov O. V., Konoplev V. N.)

This utility model relates to mechanical engineering, namely to the adjusting devices of the working processes of internal combustion engines with spark ignition. A device for regulating the composition of the combustible mixture consists of an electronic control unit associated with a source of pressure and vacuum. The pressure sensor is installed in the receiver. The device also contains a block of dampers, the inlet of which is connected to a source of pressure and vacuum, and the outlet is connected to a receiver. The output of the receiver through the pipeline is connected to the carburetor float chamber. Each flap in the flap block is connected to a stepper motor, controlled by an electronic control unit. Additionally installed pressure sensors located in the pipeline between each valve of the valve block and a source of pressure and vacuum, while additional pressure sensors are connected to the electronic control unit. The utility model improves the accuracy of adjusting the composition of the mixture over the entire range of engine load variation.

Biologists from RUDN University discovered the secret of flaxseed oil with long shelf life

Biologists from RUDN University working together with their colleagues from the Institute of Molecular Biology of the Russian Academy of Sciences and the Institute of Flax studied the genes that determine the fatty acid composition in flaxseed oil and identified polymorphisms in six of them. The team also found out what gene variations could extend the shelf life of flaxseed oil. This data can be used to improve the genetic selection of new flax breeds. The results were published in the BMC Plant Biology journal.

Researchers conducted a systematic review of articles that analyzed the effect of medicine remedies used to treat COVID-19 during pregnancy.

RUDN physician Anna Borisova, in collaboration with colleagues from Italy, used effective searches and classified 123 articles on this research topic. A literature review was conducted by searching databases of medical and biological publications: PubMed, the U.S. National Library of Medicine, and Embase (Elsevier), a biomedical database.
