Air Transport Area as an Object of State Regulation by O. V. Brusakova

“…It is concluded that the state needs to respond appropriately, i.e. to implement appropriate state regulation of the aviation area functioning during the pandemic, in particular in the implementation of air transportation in exceptional cases, the operation of airfields and airports in quarantine, aircraft parking in designated areas, standardization of issues, related to the return of passengers for canceled flights or their rebooking, providing state support to the aviation area in connection with the cessation of financial revenues from all market participants (including by allocating subsidies from the state budget, providing state aid to ensure minimal operation of airports and airfields, exemption of airlines from paying certain types of taxes for a certain period of time), etc.…”

Investigation of 4-Nitro-N, N-diphenylaniline as a chemical tracer under high pressure high temperature reservoir conditions for enhanced oil recovery applications by Subhadip Maiti, Nishant Kumar Choudhary, Kiran R. Gore, Sandeep D. Kulkarni

“…Abstract The identification of multiple distinguishable chemical tracers is crucial for determining well-to-well connectivity and optimising oil recovery processes, especially in an oilfield with a complex well matrix. In this regard, the present study investigates a novel chemical tracer 4-Nitro-N, N-Diphenylaniline (N-TPA) and compares its performance against an industry-standard water-soluble tracer, 4-Fluorobenzoic Acid (4-FBA). …”
