the rapid melting of a semi- infinite body due to the absorption of a cw laser beam radiation has been studied. the enthalpy technique for the solution of phase change problems has been used in an explicit finite difference form to calculate the transient temperature distribution in the semi-infinite body and the growth rate of the melt pool. the technique has been modified so that it is not ne...

1 Parviz L. Sadigh, MB ChB Jaime E. P. Suarez, MD Seng-Feng Jeng, MD Department of Plastic Surgery E-Da Hospital Yan-Chao District Kaohsiung City, Taiwan Sir: I nature and especially within the specialty of plastic surgery, symmetry is king. Indeed, symmetry is what we strive for in many of our reconstructive pursuits. Not surprisingly, the majority of flaps we harvest also have symmetrical ski...

Normal spiral galaxies have exponential disks and logarithmic arms (spirals). They must be interrelated and the relation is suggested to be iso-ratio. Assume you come off the disk center by such route that the ratio of the star density on your left side to the one on your right side is constant. The route (iso-ratio curve) turns out to be logarithmic spiral! Such distribution of iso-ratio densi...

The enzymatic biofuel cells (EBFCs) are considered as an attractive candidate for powering future implantable medical devices. In this study, a computational model of EBFCs based on three-dimensional (3-D) interdigitated microelectrode arrays was conducted. The main focus of this research is to investigate the effect of different designs and spatial distributions of the microelectrode arrays on...

The objective of this research is to support sustainable architecture where renewable materials (such as plant-based and soil) are used for construction. use earthen building techniques in structural design represent important construction practices mitigate the associated carbon footprint. In study we propose systems that will be constructed using such bamboo, probably most well-known material...

This research presents a compact panda-shaped wearable antenna with defected ground structure (DGS). It is fabricated using flexible material to work at 2.4-GHz industrial scientific medical (ISM) band, confirming the wireless body area network (WBAN) application requirements. The annular ring DGS and circular elliptical slots in patch aid achieving operating frequency. Good impedance bandwidth...

We present a finite-volume formulation for the lattice Boltzmann method (FVLBM) based on standard bilinear quadrilateral elements in two dimensions. The accuracy of this scheme is demonstrated by comparing the velocity field with the analytical solution of the Navier-Stokes equations for time dependent rotating Couette flow and Taylor vortex flow. To demonstrate the flexibility of the scheme, w...

The number of infrared beamlines at synchrotron facilities is expending worldwide. Due to the long wavelength of the radiation in the infrared region, the optimum collection of the emitted photons requires large opening angles, both vertically and horizontally (order of few tens of mrad). Most of the infrared beamlines use toroid shaped mirrors, or elliptical mirror to conjointly focus both the...

The present paper deals with the thermal effect model of temperature distribution in dermal layers of elliptical shaped human limbs involving two uniformly perfused tumor in dermis layer. Here the tumor is characterized by uncontrolled rates of metabolic heat generation. The normal tissues are characterized by self controlled metabolic heat generation. It is assumed that first there was only on...
