ENVIRONMENTAL MONITORING OF WATER QUALITY IN NON-CENTRALIZED WATER SUPPLY SOURCES IN THE AREA OF INFLUENCE OF LIVESTOCK BREEDING COMPLEX

The article presents the results of three years of research into the influence of livestock breeding complex on the qualitative composition of water in non-centralized water supply sources in the zone of its location. The research of water has been conducted according to the indices of water hardness, acidity, content of fluorine, iron, ammonium, nitrite and nitrates depending on remoteness of livestock breeding complex. It has been found that water hardness exceeded the average norm of the maximum allowed limit by 1,5–2 times. Content of fluorine, iron and pH index of the researched water were within regulated norms. Nitrate concentration in water exceeded maximum allowed limit by 2–3 times, at the same time the closer the wells are located to the sources of pollution, the lower the seasonal and annual changes are

Wigner crystal in snaked nanochannels

We study properties of Wigner crystal in snaked nanochannels and show that they are characterized by conducting sliding phase at low charge densities and insulating pinned phase emerging above a certain critical charge density. The transition between these phases has a devil's staircase structure typical for the Aubry transition in dynamical maps and the Frenkel-Kontorova model. We discuss implications of this phenomenon for charge density waves in quasi-one-dimensional organic conductors and for supercapacitors in nanopore materials.Comment: 4 pages, 6 figs, research at http://www.quantware.ups-tlse.f
