Impact of secondary succession in abandoned fields on some properties of acidic sandy soils
Abandonment of agricultural lands in recent decades is occurring mainly in Europe, North America and Oceania, and changing the fate of landscapes as the ecosystem recovers during fallow stage.

Strength and Water-Repelling Properties of Cement Mortar Mixed with Water Repellents [PDF]
In this study, the compressive strength and water contact angle of mortar specimens prepared by mixing two types of water repellent with ordinary Portland cement (OPC) and rapid-hardening cement mortar were measured before and after surface abrasion.

How roughness controls the water repellency of woven fabrics
The coming ban on substances of high environmental concern used to provide water repellency to fabrics creates new challenges for the textile industry. Here we show that the design of the texture of woven fabrics is an important parameter to play with in

Effect of Biomass-Burning Emissions on Soil Water Repellency: A Pilot Laboratory Study
While western U.S. wildfires have increased in intensity and scale, their impacts on soil chemical composition and hydraulic processes have received little attention, despite increasing erosion, surface runoff and flooding.
