We report efficient quasi-optic coupling of a freely propagating beam of terahertz (THz) pulses into a parallel-plate copper waveguide (with a plate separation of 108mum) and subsequent low-loss, single-TEM-mode propagation with virtually no group-velocity dispersion. Undistorted, low-loss propagation of the incoming 0.3-ps FWHM THz pulses was observed within the bandwidth from 0.1 to 4 THz for...

During vertebrate embryonic development, a portion of the ectoderm (outer layer) is set aside to make neural tissue. These cells initially form a ‘neural plate’, which later folds into a tube that will form the spinal cord and brain (Fig. 1). As the folding occurs, precursor cells in the neural plate are transformed into different neuronal subsets. Surrounding non-neural tissues initially polar...

Background: This study evaluates submuscular locked plate in the pediatric femoral shaft fractures at the age from 6 to 12 years old. Methods: A prospective study was done on 30 patients with fracture shaft femur. 18 of them were males and 12 of them were females. Fixation of all cases was done with a submuscular locked plate using the cluster technique. Results: All fractures healed within 6 w...

The theme of this paper is interaction between and within plate-based roof structures braced by branching columns and tensile members. Interaction of cross-laminated timber plate structures and branching column systems have been investigated in a previous paper [1] by utilising physical models and Genetic Algorithms. Based on this study the concept of interaction and the utilisation of compress...

The evaporation of a sessile droplet is here investigated numerically with a design of experiment approach. Boundary conditions are chosen based on forced convection in humid air, i.e., mimicking the conditions inside a dishwasher. Computational fluid dynamic simulations of an axisymmetrical droplet placed on a heated plate show that relative humidity, initial contact angle, plate temperature, ...

this study presents exact bending solution of fully clamped orthotropic rectangular plates subjected to arbitrary loads resting on elastic foundations, based on the finite integral transform method. in this method, it is not necessary to determine the deformation function because the basic governing equations of the classical plate theory for orthotropic plates have been used. a detailed parame...

this paper presents the bending analysis of annular plates by the indirect trefftz boundary approach. the formulation for thin and thick plates is based on the kirchhoff plate theory and the reissner plate theory. the governing equations are therefore a fourth-order boundary value problem and a sixth-order boundary value problem, respectively. the trefftz method employs the complete set of solu...
