Lateral–directional stability is a critical issue for the design of any kind aircraft. For hypersonic waverider, nonaxisymmetric, flat, and slender geometric feature makes it susceptible to problem lateral–directional instability. Therefore, influence on static dynamic waverider studied so as enable designer consider this in preliminary aircraft stage. A series power-law waveriders generated at...

We evaluated the microstructure of the edges of currently available foldable intraocular lenses (IOLs). The methodology used assisted an IOL manufacturer (Hoya, Japan) to optimise the edge profile of its lenses. Ten designs of hydrophobic acrylic, six designs of silicone and 24 designs of hydrophilic acrylic IOLs were imaged under scanning electron microscopy (SEM), and the photographs were imp...

THE MIARSUPIALIZATION operation for pilonidal sinuses was first described by Buie,3 in 1938. In his procedure, the sac was completely unroofed and the overhanging skin and adjacent edge of the sac was excised. The remaining skin edge was sutured to the edge of the sac wall. He believed that the histologic nature of the sac wall, and its similarity to skin, made the lining peculiarly suited for ...

The cranial cruciate ligament (CrCL) runs from the caudomedial part of the lateral condyle of the femur diagonally across the intercondylar fossa to the cranial intercondyloid area of the tibia. The caudal cruciate ligament (CaCL) runs from the lateral surface of the medial femoral condyle caudodistally to the lateral edge of the popliteal notch of the tibia. The cruciate ligaments consist of t...

A retrospective analysis was performed of eight patients with an open triradiate cartilage, who underwent resection for osteosarcoma and reconstruction of the proximal femur with a hemiarthroplasty, in order to identify changes of acetabular development. An analysis of the centre-edge angle, teardrop-to-medial prosthesis distance, superior joint space, teardrop-to-superior prosthesis distance, ...

Abstract We report on the effective passivation of cut edges n-type (100) crystalline silicon by forming thin oxide layers achieved heat treatment in liquid water at 90 °C for 2 h followed heating an air atmosphere 300 1 h. The mechanical with (110) oriented cleaved edge markedly decreased photo-induced minority carrier lifetime τ eff to 6.9 × 10 −4 s, which was 0.22 times initial value 3.2 −3 ...

The initiation of furrow formation is disrupted when microtubule elongation to the cell surface is inhibited either by promoting microtubule disassembly with hydrostatic pressure or by stabilizing the mitotic astral microtubules with taxol. The pressure studies confirmed Rappaport's earlier observation that stimulation of furrow formation is produced by a pair of asters and does not require chr...

Dorsal closure is an essential stage of Drosophila embryogenesis and is a powerful model system for morphogenesis, wound healing, and tissue biomechanics. During closure, two flanks of lateral epidermis close an eye-shaped dorsal opening that is filled with amnioserosa. The two flanks of lateral epidermis are zipped together at each canthus ("corner" of the eye). Actomyosin-rich purse strings a...

A novel calibration technique has been developed for lateral force microscopy (LFM). Typically, special preparation of the atomic force microscope (AFM) cantilever or a substrate is required for LFM calibration. The new calibration technique reported in this paper greatly reduces the required preparation processes by simply scanning over a rigid step and measuring the response of the AFM photod...
