Effects of hydrophobicity on splash erosion of model soil particles by a single water drop impact [PDF]

, 2013
Raindrop impact can be a major contributor to particle mobilization for soils and other granular materials. In previous work, water repellent soils, comprised of hydrophobic particles, have been shown to exhibit greater splash erosion losses under ...

Effect of Particle Size on Droplet Infiltration into Hydrophobic Porous Media As a Model of Water Repellent Soil [PDF]

, 2011
The wettability of soil is of great importance for plants and soil biota, and in determining the risk for preferential flow, surface runoff, flooding,and soil erosion. The molarity of ethanol droplet (MED) test is widely used for quantifying the severity

The potential attractant or repellent effects of different water types on oviposition in Aedes aegypti L. (Dipt., Culicidae) [PDF]

, 2003
The selection of oviposition sites by the yellow-fever mosquito, Aedes aegypti , was studied in the laboratory. The repellent or attractant effects of salinity and the presence of bacteria in water collected from a local community on the Brazilian coast ...

Experimental Study on Water Lubrication Characteristics of Full-Flat Thrust Bearing with Partial Water-Repellent Surface

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2013
In this study, a flat thrust bearing is developed by active exploiting the slip flow generated on a water-repellent surface. In order to produce a load, this bearing has a structure that generates a pressure flow by using the discontinuity of shear flow ...

Synthetic water repellent soils for slope stabilization [PDF]

, 2017
Water repellent soils, or non-wettable soils, are described as having delayed wetting of the soil surface and water infiltration, and have been studied by soil scientists and agriculturists for decades.

The influence of water repellent products on the chromatic modifications of the ceramic brick

Materiales de Construccion, 2011
Chromatic variation, colour and luminosity, undergone by the ceramic support protected by the incorporation of a treatment with water repellent products, is analysed. A new methodology is suggested, based on RGB model where quantifiable values from each
