Stress wave propagation in a metal–plastic bonded laminate immersed fluid is investigated based on linear viscoelastic theory. The reflection spectrum theoretically derived for normal incidence. For the incidence from plastic layer, amplitude of shown to have local minima at resonance frequencies every single layer. Resonance metal layer leads destructive interference reflected components, whil...

This case report presents an implant-aided prosthetic treatment in which peri-implant plastic surgery techniques were applied in combination to satisfactorily attain functional aesthetic expectations. Peri-implant plastic surgery enables the successful reconstruction and restoration of the balance between soft and hard tissues and allows the option of implant-aided fixed prosthetic rehabilitation.

an evolutionary structural optimization (eso) method is used for plastic design of frames. based on safe theorems some criteria are derived and made an effort to satisfy them during the optimization process. in this regard, equilibrium is checked and yield condition is gradually satisfied during the optimization process. in this method, the amount of used material and the stiffness for each ele...

A new wave energy flow (WEF) map concept was proposed in this work. Based on it, an improved technique incorporating the laser scanning method and Betti's reciprocal theorem was developed to evaluate the shape and size of damage as well as to realize visualization of wave propagation. In this technique, a simple signal processing algorithm was proposed to construct the WEF map when waves propag...

Wave-mixed bioreactors have increasingly replaced stainless steel stirred tank reactors in seed inoculum productions and mammalian cell-based process developments. Pre-sterilized, single-use plastic bags are used for cultivation, eliminating the risk of cross-contamination and cleaning procedures. However, these advantages come with high consumable costs which is the main barrier to more uptake...

We propose and demonstrate a new technique for evanescent wave chemical sensing by writing long period ~ in a bare multimode plastic clad silica tiber. The sensing length of the present sensor is only IQ mm, but is as sensi1iIt; a conventional unclad evanescent wave sensor having about 100 mm sensing length. The minimum measurabkl1! centratioll of the sensor reported here is 10 nmoUl and the op...

The mechanism of blast damage to steel-clad concrete-filled steel tube (SCCFST) arched protective doors is studied using the dynamic response characteristics such loads under action shock wave loads, and ultimate load-bearing capacity formula derived based on “plastic hinge” mode limit analysis, which explores effect wave. design parameters each component door subjected waves discussed. Results...

This study focuses on how wave–current and wave–turbulence interactions modify the transport of buoyant particles in the ocean. Here the particles can represent oil droplets, plastic particles, or plankton such as fish eggs and larvae. Using the General Ocean Turbulence Model (GOTM), modified to take surface wave effects into account, we investigate how the increased mixing by wave breaking and...

We analyze simple shear and torsion of single crystal copper by employing experiments, molecular dynamics simulations, and finite element simulations in order to focus on the kinematic responses and the apparent yield strengths at different length scales of the specimens. In order to compare torsion with simple shear, the specimens were designed to be of similar size. To accomplish this, the ra...
