We deal here with three metastable systems: 1° – the dowser texture, 2° supertwisted cholesterics and 3° hypotwisted cholesterics. outline remarkable properties of tropisms texture stemming from its low symmetry, we show that, using setups called Dowsons Colliders, nematic monopoles can be nucleated, set into motion brought collisions in texture. Subsequently, point out that nucleation dislocat...

Abstract Purpose Soil water repellence causes uneven soil wetting which can constrain dryland crop and pasture establishment yield. The same processes are likely to affect nutrient availability from fertiliser, but the effects of on growth nutrition per se have seldom been reported. Here, we investigated early wheat ( Triticum aestivum cv. Mace) uptake responses repellence. Methods Wheat was fu...
