With the expanding electrification in all sectors of transport, it is necessary to look for new efficient solutions propulsion systems use air transport. One approaches can be electric ducted fans (EDFs), especially in, but not limited to, case unmanned aerial vehicles with vertical takeoff and landing.

The number of regions of the type Cn Shi arrangement in Rn is (2n + 1)n. Strikingly, no bijective proof of this fact has been given thus far. The aim of this paper is to provide such a bijection and use it to prove more refined results. We construct a bijection between the regions of the type Cn Shi arrangement in Rn and sequences a1a2 . . . an, where ai ∈ {−n,−n+1, . . . ,−1, 0, 1, . . . , n−1...

Although many practices are moving towards delivering that goal, recent national patient surveys have reported a deterioration in patients' reports of doctor availability. What practice factors contribute to patients' perceptions of doctor availability? METHOD A cross sectional patient survey (11,000 patients from 54...
