Lightweight carbonized wood has a hierarchically 3D porous framework and orthotropic channels along the growth direction, which demonstrate great potential for multifunctional electronic materials. Herein, with outstanding electromagnetic interference (EMI) shielding effectiveness (SE), high thermal conductivity, excellent Joule heating property is fabricated. It also exhibits highly anisotropi...

We study the intrinsic heat equation governing the motion of plane curves. The normal velocity v of the motion is assumed to be a nonlinear function of the curvature and tangential angle of a plane curve Γ. By contrast to the usual approach, the intrinsic heat equation is modified to include an appropriate nontrivial tangential velocity functional α. Short time existence of a regular family of ...

BACKGROUND Fluorescence photodynamic diagnosis (PDD) cystoscopy is gaining credence in the diagnosis and surveillance of bladder cancer. It combines normal white light cystoscopy with periodic blue light examination of the bladder pre-instilled with a tumour selective porphyrin, hexa-aminolevulinic acid (hexa-ALA).1 This method detects areas of fluorescent tissue suggestive of tumour or carcino...

Introduction: The purpose of this study was to estimate the secondary cancer risk of thyroid for standard radiotherapy methods which are commonly used for breast cancer patients. Materials and Methods: Sixty-four breast cancer patients (their age range was around 50 years old) who referred to Seyed- Al- Shohada hospital (Isfahan, Iran) were included in this ...

This article aims to have a glimpse into the effect of spinning tool parameters (focusing on its diameter, attack angle, nose radius, and feed) by applying explicit code commercial finite element analysis software LS-DYNA. The preliminary results show that greater axial feed, loads generated in axial, tangential, radial directions. At same time, larger more elements are parallel direction from ...

In this note we investigate the behavior of polar tangential angle a general plane curve, and in particular prove its monotonicity for certain curves monotone curvature. As an application give (non)existence results obstacle problem involving free elasticae.

Most descriptions of collision events introduce coefficients friction and tangential restitution which vary significantly with the impact angle, in contrast independence normal coefficient this parameter. A redefinition based on idea that effects can be treated as being mutually independent, provides a satisfactory description experimental data using ‘constant’ independent angle. This friction-...

A method to calculate the elastic shakedown limit of transportation systems (e.g. pavements and railways) supported by geogrid reinforced soils is presented. For first time, lower-bound theory combined with a strength-based simulation approach, resulting in rapid quantify benefit geogrids on limit. It allows decoupling stress generation calculations, meaning it straightforward implement, requir...

Metasurfaces formed by monopole and dipole resonators are studied theoretically. The Helmholtz or membranes vibrating on the first eigenfrequency; ones spheres springs second eigenfrequency. It is shown that acoustic properties of metasurface built-in can be described an equivalent impedance, which characterizes a normal forcing to surface, whereas this impedance not suitable for resonators, be...
