New experimental data on the frequency and damping of Faraday water waves in glass tanks are presented to demonstrate the contact-line effect on free surface flows. We find a complicated nonlinear relationship between wave frequency and amplitude near contact lines: The amplitude dispersion for decaying standing waves directly progresses from a nonlinear regime due to large amplitude to a regim...
PURPOSE Outstanding improvements in vision can theoretically be expected using contact lenses that correct monochromatic aberrations of the eye. Imperfections in such correction inherent to contact lenses are lens flexure, translation, rotation, and tear layer effects. The effects of pupil size and accommodation on ocular aberration may cause further difficulties. The purpose of this study was ...
The cell phone is one of the potential Information Communication Technologies (ICTs) in agricultural development especially in developing countries like Bangladesh. Thus, this paper deals with the farmers’ communication with the agricultural extension agents using mobile phone. The study was conducted in Mymensingh District in Bangladesh. Data were collected from a sample of 110 farmers while b...
