In this paper, we prove the local well-posedness of the water wave problem with surface tension in the case of finite depth by working in the Eulerian setting. For the flat bottom, as surface tension tends to zero, the solution of the water wave problem with surface tension converges to the solution of the water wave problem without surface tension.

The capillary rise technique has been used to experimentally study the “surface tension” of liquid marbles formed by encapsulating water droplets with polytetrafluoroethylene (PTFE) powder of 1, 35, and 100 μm particle size. In a typical experiment, a glass capillary tube was inserted into a water marble to measure the capillary rise of the water. The Laplace pressure exerted by the water marbl...

The widely supported cohesion–tension theory of water transport explains the importance of a continuous water column and the mechanism of long-distance ascent of sap in plants (Dixon 1914, Tyree 2003, Angeles et al. 2004). The evaporation of water from the surfaces of mesophyll cells causes the air–water interface to retreat into the cellulose matrix of the plant cell wall because the cohesion ...

OBJECTIVES To investigate the correlation and agreement between the intraocular pressure peaks detected during the water drinking test and the modified diurnal tension curve in untreated glaucomatous eyes. INTRODUCTION It has been suggested that the intraocular pressure peaks detected during the water drinking test predict the peaks observed during a 24-hour diurnal tension curve. A more feas...

in order to compare effect of magnetic field and frigate surfactant to enhance the efficacy of iodosulfuron-methyl-sodium plus mesosulfuron-methyl (chevalier) to control wild oat, a greenhouse experiment of dose-response was conducted. treatments were 0, 3, 6, 12, 18 and 24 doses g a.i. ha-1 of chevalier (i) without treatment, (ii) with frigate % 0.1 v/v, (iii) with magnetic field, and (iv) fri...

Many Bacillus subtilis strains swarm, often forming colonies with tendrils on agar medium. It is known that B. subtilis swarming requires flagella and a biosurfactant, surfactin. In this study, we find that water surface tension plays a role in swarming dynamics. B. subtilis colonies were found to contain water, and when a low amount of surfactin is produced, the water surface tension of the co...

In this paper the density and temperature dependencies of surface tension are investigated. Using the Lennard-Jones (12,6), as an effective pair interaction potential, a linear expression is derived for isotherms of g /r2  versus r2 for some normal and ChloroFluoroCarbons (CFCs)</...
