Facial Rejuvenation Enhancing Cheek Lift [PDF]
Archives of Plastic Surgery, 2017 Supported by recent literature on the signs of aging of the middle and lower face, our clinical research has documented a loss of volume of the deep structural components of the central face and a progressive descent of the nasolabial fat and the jowl fat, leading to facial fragmentation.

Evolution of the leading-edge vortex over a flapping wing mechanism
Journal of Mechanical Engineering and Sciences, 2020 Leading-edge vortex governs the aerodynamic force production of flapping wing flyers. The primary factor for lift enhancement is the leading-edge vortex (LEV) that allows for stall delay that is associated with unsteady fluid flow and thus generating ...

Application Research of Flow Control Using Co-flow Jet on a Vertical Tail
Hangkong gongcheng jinzhan, 2022 The aerodynamic characteristics of the vertical tail of an aircraft are directly related to the size and weight of the vertical tail. Increasing the lift force of the vertical tail using flow control can further reduce the size of the vertical tail,which

Coriolis effects enhance lift on revolving wings [PDF]
Physical Review E, 2015 At high angles of attack, an aircraft wing stalls. This dreaded event is characterized by the development of a leading edge vortex on the upper surface of the wing, followed by its shedding which causes a drastic drop in the aerodynamic lift. At similar angles of attack, the leading edge vortex on an insect wing or an autorotating seed membrane remains
