Takeoff/landing Assessment of an Hsct with Pneumatic Lift Augmentation
Pneumatic technologies, such as Circulation Control airfoils, have been experimentally demonstrated to generate very high lift coefficients at low angles of attack. These blown airfoils offer great potential for advanced subsonic transports. Yet, the potential of this particular pneumatic technology is not limited to subsonic aircraft. In fact, Circulation Control has been chosen as an enabling...
متن کاملDevelopment of a Prototype Test Rig for a Cryogenic, Marine, Heavy Lift, Buoyancy System
There is a continual search for new methods of marine salvage and decommissioning of structures in the open sea in order to improve control and lower operational costs. The concept design of a lightweight, cryogenic, marine, heavy lift, buoyancy system has been investigated. The objective is to be able to raise or lower high mass objects controlled solely from a surface support vessel. The over...
متن کاملAutologous Periosteum-Derived Micrografts and PLGA/HA Enhance the Bone Formation in Sinus Lift Augmentation
Sinus lift augmentation is a procedure required for the placement of a dental implant, whose success can be limited by the quantity or quality of available bone. To this purpose, the first aim of the current study was to evaluate the ability of autologous periosteum-derived micrografts and Poly(lactic-co-glycolic acid) (PLGA) supplemented with hydroxyl apatite (HA) to induce bone augmentation i...
متن کاملCasimir Buoyancy
We study the Casimir force on a single surface immersed in an inhomoge-neous medium. Specifically we study the vacuum fluctuations of a scalar field with a spatially varying squared mass, m 2 + λ∆(x − a) + V (x), where V is a smooth potential and ∆(x) is a unit-area function sharply peaked around x = 0. ∆(x − a) represents a semi-penetrable thin plate placed at x = a. In the limits {∆(x−a) → δ(...
متن کاملMalar augmentation assessed by magnetic resonance imaging in patients after face lift and fat injection.
BACKGROUND Restoration of cheek volume is recognized as an important part of facial rejuvenation. However, there are no previous studies that have determined whether any soft-tissue technique is effective for achieving lasting malar augmentation. METHODS This study prospectively evaluated a subset of five patients who had deep-plane face lifts with fat injection, and other facial cosmetic pro...
