Performance evaluation of water-repellent combat uniforms using a static manikin and human subjects under a rainfall tower system

open access: yesFashion and Textiles, 2021
The purpose of the present study was to evaluate the water-repellent properties of newly-developed combat uniforms using a rainfall tower system. Two types of water-repellent- combat uniforms with an identical level of water repellency through textile ...

Investigation of Water-Repellent Thrust Bearing

open access: yesTribology Online, 2010
In this study, the flat thrust bearing was developed by actively exploiting the slip flow generated on a water-repellent surface. In order to produce a load, bearing has a structure that generates pressure flow by using the discontinuity of the shear ...

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

open access: yesMateriales 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

Is the Rhizosphere Temporarily Water Repellent?

open access: yesVadose Zone Journal, 2012
The rhizosphere has a controlling role in the flow of water and nutrients from soil to plant roots; however, its hydraulic properties are not well understood. As roots grow, they change the pore size distribution of the surrounding soil. Roots release polymeric substances such as mucilage into their rhizosphere. Microorganisms living in the rhizosphere

Water Movement and Finger Flow Characterization in Homogeneous Water-Repellent Soils

open access: yesVadose Zone Journal, 2018
Soil water repellency (SWR) is a widespread property in soils around the world. It influences soil water movement and causes unstable flow. The mechanics of finger flow occurrence in water-repellent soils are not clearly understood.

Water–soil interactions: Unravelling the processes and stages involved in the wetting of water repellent soils

open access: yesJournal of Hydrology X, 2023
The water repellent behaviour of soils is a widely studied phenomenon given its implications for infiltration, runoff, erosion and preferential flow. However, the principles underlying the eventual penetration of water into affected soils remain poorly ...
