With the development of plastic surgery techniques, computer aided approach has become a significant method in medical plastic surgery. In order to solve effects on surgical results made by the surface of a wound in craniofacial cosmetic surgery, accurate preoperative preparation is usually required for the surgery. This paper summarizes the application of computer aided technology in craniofac...

The fatigue growth of multiple cracks, of arbitrary lengths, emanating from a row of fastener holes in a bonded, riveted, lap joint in a pressurized aircraft fuselage is studied. The effects of residual stresses due to a rivet misfit, and of plastic deformation near the hole, are included. A Schwartz Neumann alternating method which uses the analytical solution for a row of multiple colinear cr...

In this study, we propose one-step chemical modification of plastics for bonding various plastics with poly(dimethylsiloxane) (PDMS) elastomer at room temperature. This was realized by anchoring poly[dimethylsiloxane-co-(3-aminopropyl)methylsiloxane] (amine-PDMS linker), a chemical composed of a PDMS backbone incorporating an amine side group, on the surface of thermoplastics. Following corona ...

Magnesium-28 was applied to specific leaves of bean (Phaseolus vulgaris) and barley (Hordeum vulgare) plants. After 24 hours, as much as 7% of the absorbed Mg was exported from the treated bean leaves and 11% was transported basipetally from the treated zone of the barley leaves. Transport of Mg did not occur past a heat-killed section of the treated leaf, thereby indicating that translocation ...

A case of chronic sternal sinus is described in which exploration revealed a loose patch of Teflon felt which had been used three years earlier in reconstructing the outflow tract of the right ventricle in a case of congenital pulmonary stenosis. Teflon, a synthetic polymer of low biological reactivity, while being suitable in its solid sheet form for use in plastic reconstructive surgery, is n...

Sheet metal forming as well mechanical joining demand increasingly accurate and efficient material modelling to capture large deformations, the inherent sheet orthotropy even process-induced damage, which is expected be influential. To account for strains additive logarithmic strain space utilised that enables a straightforward incorporation of plastic anisotropy, herein modelled by Hill48 yiel...

We study the scaling properties of randomly folded aluminum sheets of different thicknesses h and widths L . We found that the fractal dimension D=2.30+/-0.01 and the force scaling exponent delta=0.21+/-0.02 are independent of the sheet thickness and close to those obtained in numerical simulations with a coarse-grained model of triangulated self-avoiding surfaces with bending and stretching ri...
