When a drop is placed on a flat substrate tilted at an inclined angle, it can be deformed by gravity and its initial contact angle divides into front and rear contact angles by inclination. Here we study on evaporation dynamics of a pure water droplet on a flat solid substrate by controlling substrate inclination and measuring mass and volume changes of an evaporating droplet with time. We find...

conclusions since international accreditation standards have clearly stated all processes and organizations are required to implement them, obtaining the relevant licenses can ensure health tourist that they have selected the right country and the right hospital to access their desired medical services. results implementation of international accreditation standards has a significant effect on ...

In this paper, kinematic characteristics of writing are compared in 5 patient with writer’s cramp who performed a set of standardized writing task. The kinematic characteristics thumb and forefinger force before and during cramp. The effect of writing on different inclined supporting surfaces is also investigated. Our results indicate that inclined surfaces aspects of writing discomfort in writ...

Four bonobos, seven gorillas, and six orangutans were presented with two small rectangular boards on a platform. One of the boards had a piece of food under it so that it acquired an inclined orientation whereas the other remained Xat on the platform. Subjects preferentially selected the inclined board. In another experiment, subjects were initially presented with two inclined boards and a tran...

A new kind of metamaterial, an array of periodic gold rod pairs standing on gold substrate, is introduced in this paper. A commercial electromagnetic mode solver, the High-Frequency Structure Simulator, is employed to explore the propagation property of electromagnetic waves in this system. When an S -polarized electromagnetic (EM) wave propagates along the substrate surface, strong magnetic re...

We describe recent investigations on the impact behaviour of liquid drops onto chemically structured surfaces. The surface patterns were prepared via photochemical attachment of polymer molecules with different hydrophilicities using self-assembled monolayers of benzophenone bearing silanes. Immobilization of the polymer monolayers was followed by an ablation process to generate a chemical surf...

To investigate hydrodynamic processes above and within river beds, laboratory experiments have been performed to quantify the interaction between turbulent flow and pressure fluctuations at a porous gravel bed. A 2-D Particle Image Velocimetry (PIV) system measuring in streamwise vertical or horizontal planes above the gravel layer was used, synchronized with a pressure sensor array of 16 minia...
