Novel smart material and actuator technology will ultimately lead to the development of aerodynamically efficient air vehicles capable of radical shape change that can accomplish various mission types with superior performance. In this research, active skins based upon pressurized flexible matrix composites (FMCs) are investigated for trailing edge flap control of a glider wing. The new active ...

Inadequate venous drainage can lead to congestion and necrosis of flaps used in the repair of defects, thereby elevating the risk of flap failure. In this study, we sought to test the hypothesis that the venous drainage was better in flow-through flaps than in conventional dorsalis pedis free flaps used in the repair of dorsal foot defects. In this retrospective study, we investigated the data ...

OBJECTIVE To study scrotal microvascularization and apply the findings to the design of reliable skin flaps for reconstructive surgery of complex urethral or panurethral stenoses. MATERIALS AND METHODS In 15 cryopreserved male cadavers, scrotal skin vascularization was explored using macro- and microdissections, and the scrotal sac made transparent using the Spalteholtz method. A meticulous d...

Successful eyelid reconstructions have been reported when using an axial nasal chondromucosal flap based on the dorsal nasal artery. The present study aimed to present a detailed anatomical description of the blood supply of the lateral nasal region and the angular artery, in order to propose the angular vessels as a new vascular pedicle for the island nasal chondromucosal flap. A total of 11 c...

the distal third of the tibia, ankle and heel area is difficult to reconstruct. for small to medium size defects, local flaps are often an easier alternative than free flap. in lower limb surgery, the sural flap is based on this principle and this flap is becoming increasingly popular. the distally based superficial sural artery flap, first described as a distally based neuro skin flap by masqu...

BACKGROUND During surgery, circulation changes in the deep inferior epigastric perforator free flap (DIEP). Although blood flow is an important parameter for surgical outcome, little research has been performed on this topic, especially during the process of transplantation. This study examined the pattern of perfusion of DIEP flaps over time. METHODS In all, 16 flaps were studied in 14 DIEP ...

BACKGROUND For reconstructing moderate-to-high projection breasts in nulliparous patients with insufficient abdominal tissue or prior abdominal surgeries, a unilateral inferior gluteal artery perforator (IGAP) flap is an alternative procedure. In patients with slim hips, however, unilateral gluteal tissue is insufficient and inferior gluteal crease displacement may develop postoperatively. Dono...

BACKGROUND Surgical ablation for locally advanced breast cancer results in large chest wall defects, which can then be managed with local flaps or skin grafts. The purpose of this article is to evaluate the outcomes of three types of local skin flaps. METHODS Among 25 local flaps in 24 patients, 6 were bilateral advancement (BA) flaps, 9 were thoracoabdominal (TA) flaps, and 10 were thoracoep...

Abstract This paper gives a summary of dedicated experiments on the shock interaction induced heat flux augmentation, by means tests carried out in hypersonic wind tunnel H2K. The first test case is devoted to boundary layer flat plate. impact has been varied changing free stream parameters and position generator, i.e. impingement point distribution determined using surface temperature data mea...
