Abstract Introduction The planning of transport infrastructures in France has been marked by three major developments: the European reform concerning the opening of rail transport to Male Contraceptives competition, the privatisation of semi-public motorway concession-holding companies, and the use of public-private partnership contracts.This artic
The results of numerical research of a soft type airship aerodynamic characteristics in subsonic flow of viscous gas are received for the Wormwood airship locating near to a screen and having the working propellers.The influence of propeller rotation and relative distance of the airship to the screen on values of its aerodynamic normal and longitud
For a scenario of a close flyby of a compact star near a spinning black hole, we provide analytical and numerical estimates for the shift of trajectory periastron due to relativistic (beyond post-Newtonian) effects.More specifically, we derived a generalized expression (not Training limited to quasi-circular or elliptical orbits) directly linking t
Energy management is becoming one of the major research fields as the world is suffering from energy and oil/gas scarcities, coupled with the increase in greenhouse gases emissions and pollution.Refrigeration and air-conditioning equipment are known to be one of the largest electric consuming sectors, reaching around half the global energy consumpt
