Airborne and aerosol pathogen transmission modeling of respiratory events in buildings: An overview of computational fluid dynamics.

Pathogen droplets released from respiratory events are the primary means of dispersion and transmission of the recent pandemic of COVID-19. Computational fluid dynamics (CFD) has been widely employed as a fast, reliable, and inexpensive technique to support decision-making and to envisage mitigatory protocols. Nonetheless, the airborne pathogen droplet CFD modeling encounters limitations due to the oversimplification of involved physics and the intensive computational demand.

Industrial biowastes treatment using membrane bioreactors (MBRs) -a scientometric study.

In the current global situation, the release of large amounts of potential effluents into the environment is considered as one of the most important and challenging issues. Innovations in the treatment methods to deal with this problem are among the research priorities within the scientific communities. Even though innumerable methods including physicochemical and biological have been used, yet no proper sustainability of the methods have been introduced.
