A z-pinch capillary plasma as an alternative active medium of soft X-Ray lasers was studied experimentally and theoretically. The theoretical analysis was based on the self consistent solution of the so called “snow plow” model. The dynamics of pinched plasma is determined by the capillary parameters and by the time dependence of electrical current passing through it. The current time dependenc...

Accurate description of soil surface topography is essential because different tillage tools produce different soil surface roughness conditions, which in turn affects many processes across the soil surface boundary. Advantages of fractal analysis in soil microrelief assessment have been recognised but the use of fractal indices in practice remains challenging. There is also little information ...

This study examines the reasons farmers in East-Central Illinois continue to use controversial agricultural practices in the context of extreme criticism. Such practices – conventional plow tillage, application of potent agricultural chemicals, farming up to river banks – are attacked from diverse sources as inattentive to environmental conservation. Our results suggest these practices are impo...
