The effect of the tilt angle of metal film on the transmissivity of subwavelength holes in optically thick metal film is investigated. The transmission efficiency is found can be highly dependent on the tilt angle. It is also found that when the input photons are polarized not along the eigenmode directions of surface plasmon polariton, a birefringent phenomenon is observed when the array with ...

PURPOSE This research was conducted to compare supine and standing Merchant views, to observe radiographic changes of the patellofemoral joint according to weight-bearing conditions, and to evaluate correlation factors affecting patellofemoral joint indices. MATERIALS AND METHODS Forty-four patients without skeletal problems were selected for this study. Patellar tilt angle, lateral patellofe...

In this work we investigate the interplay between flow and boundary condition effects on the orientation field of a thermotropic nematic liquid crystal under flow and confinement in a microfluidic device. Two types of experiments were performed using synchrotron small-angle X-ray-scattering (SAXS). In the first, a nematic liquid crystal flows through a square-channel cross section at varying fl...

BACKGROUND Rice farming activities involve prolonged manual work and human-machine interaction. Prolonged farming risk-exposure may result in lower limb malalignment. This malalignment may increase the risk of lower extremity injury and physical disabilities. However, the prevalence and factors associated with lower extremity malalignment have not yet been reported. This study aimed to investig...

Abstract: The tilt angle with the horizon (with respect to the ground) of the solar energy system affects the amount of solar radiation received. This paper suggests a simple and universal method to obtain the optimum tilt angles by estimating the monthly mean daily global solar radiation on tilted surfaces facing directly towards the equator, which is based on monthly average daily global sola...

The probe-coil’s lift-off and tilt variations will cause noise signals that can obscure the valuable signals when the surface inspection is performed. Prevention of noise signals due to lift-off and tilt variations is an important element in most eddy current inspections. In this paper, the electromagnetic field and impedance of a cylindrical probe-coil have been calculated numerically for arbi...

Tablets and mobile devices are used in various situations in everyday life. Several researchers have reported the effectiveness of tilting a tablet in enabling a high degree of usability. Tablets are also increasingly popular in elementary school classrooms. The use of tablets in schools is considered to be different from their common use in daily life because students have many opportunities t...

The effects of passive head-up tilt on systolic time intervals were assessed in 18 patients with mitral valve prolapse. In addition to causing prolongation of the pre-ejection period and shortening of left ventricular ejection time, this circulatory stress led to progressive shortening of the Q to click interval. In 1 patient, a systolic click became audible which had not been heard in the supi...
