Wind generator vanes can suffer degradation by erosion, particularly at their outer edge, produced by particles (dust, sand, etc.) which are present suspended in the air. Because of this, the ever increasing presence of wind parks in zones of extreme climate make it puts an onus on optimising the protection coating material, with the aim of guaranteeing good yields, even in the most extreme conditions. The main parameters that affect this phenomenon are, on the one hand, gel-coat...

The thousands of oval lakes that dot Alaska's North Slope are some of the fastest-growing lakes on the planet. Ranging in size from puddles to more than 15 miles in length, the lakes have expanded at rates up to 15 feet per year, year in and year out for thousands of years. The lakes are shaped like elongated eggs with the skinny ends pointing northwest. How the lakes grow so fast, why they're oriented in the same direction and what gives them their odd shape has puzzled geologists for...

Erosion is the process by which rock and soil are taken from the surface of the Earth by exogenetic processes like wind or the flow of water, and then transported and deposited in another location. While erosion is a natural process, human activities have increased by 10 to 40 times the rate at which erosion is happening globally. Excessive erosion results in problems such as desertification, decreases in agricultural productivity because of land degradation, sedimentation of waterways,...
