Flap of a Butterfly's Wings
<p>The goal of this thesis is to draw attention to the often overlooked work that is done by activists and their networks when it comes to influencing international policy and law. The case study looks at the “Comfort Women” issue, an unresolved conflict from when the Japanese Imperial Army forced …

Aerodynamics and aeroacoustics of flap side-edges
… the aerodynamics and aeroacoustics of a flap side-edge. A porous side-edge treatment was applied to the flap side-edge in an attempt to reduce airframe noise. Measurements taken as part of the experimental study were forces, on-surface pressures, particle image velocimetry, hotwire …

An Experimental Investigation of Blown-Flap Airfoils
… In this thesis, the performance of blown-flap wings is investigated to provide both performance estimates and validation data for future work on blowing enabled aircraft. A quasi 2-dimensional wind tunnel model is used to conduct surveys on both the performance and flow characteristics of …

Flap Endonuclease 1 ensures telomere replication and stability
… of one DNA replication and repair protein, Flap Endonulcease 1: FEN1), in telomere replication and maintenance. I demonstrate that FEN1 is essential for the efficient replication of telomeres through its ability to re-initiate stalled replication forks. FEN1 depletion leads to telomere …

Flight envelope protection using flap hinge moment measurement
… experimental investigation of the sensitivity of flap hinge moment to airfoil surface contamination was conducted at the University of Illinois at Urbana-Champaign Aerodynamics Research Lab. Tests were conducted on two airfoil models, an NACA 3415 and an NACA 23012, at Reynolds numbers of 1.8 × …

Helicopter rotor smoothing with a continuous trailing - edge flap
… process with a continuous trailing-edge flap (CTEF). The CTEF is a monolithic active blade control design with no mechanical linkages compared to the conventional discrete trailing-edge flap (DTEF). In this design, micro fiber composite (MFC) layers are embedded inside the airfoil to …

Functional Status of the Donor Limb of Anterolateral Thigh Flap
The anterolateral thigh flap (ALT) is based on the perforators of the descending branch of the lateral circumflex femoral artery. As there are several anatomical variations of the lateral circumflex arterial system, muscle dissection is unavoidable when skin perforator vessels run through the …

Design and Aerodynamic Analysis of Continuous Mold-line link flap
Flaps used in modern aircraft are known to produce high-intensity noise. Their blunt side edges of the wing's flap produce vorticial wakes which are the main contributors to the noise generated. A concept called continuous mold-line (CML) link flap has been studied rigorously for its impact on the …

Design of a Mechanically Divinatory I Ching Split-Flap Display Device
… the design and modeling of a mechanical split-flap display device with anthropological applications in connections to the I Ching, an ancient Chinese divination technique. The device was designed to be an interactive mechanical system to introduce new perspective on different areas of the …

Performance of an airfoil with a power-saving, tab-assisted flap system
… input power with the use of a tab-assisted flap. Wind tunnel tests were conducted at the University of Illinois at Urbana-Champaign (UIUC) on a NACA 3415 airfoil model with a flap including a trim tab. Measurements were taken for two configurations: a baseline fixed tab case where tab …

Optical sensors for the in vivo assessment of flap perfusion in plastic surgery
… Deep Inferior Epigastric Perforator (DIEP) free flap where skin and adipose tissue along with their blood supplies are transferred from the lower abdomen to the chest. The success of free flap reconstructive surgery depends strongly on the maintenance of adequate perfusion in the flap. Early …

Serum Complement Reactive Protein (CRP) Trends Following Free Flap in Lower Extremity Reconstruction
Infectious complication remains a major cause of flap failure. Serum complement reactive protein (CRP) level is a customary measure for early recognition of infections. The aim of this study was to describe the time course of CRP in patients with free flap for trauma and chronic wound problems of …

Rotor Blade Flap-Lag Stability and Response in Forward Flight in Turbulent Flows
… effect of random air turbulence on the coupled flap-lag motion of a helicopter rotor blade in forward flight is investigated. By assuming white noise turbulence and applying a special case of the stochastic averaging procedure, equations are developed which describe the stochastic first and …

Superficial temporal artery flap: its development and application in the dog and cat
… muscle. A superficial temporal artery (ST A) flap was developed in 9 dogs [ group A (n=5), group B (n=4)]. Ligation of the superficial tetnporal artery in the control dogs (n=5), rendered flaps dependent on the subdermal plexus. Dogs in group A (n=5) and the control group (n=5) had flap …
