Ensuring stability of economic development, an energy and ecological safety is connected with increase in energy efficiency and decrease in power consumption of economy. The main indicator of resource intensity is power consumption. power consumption characterizes amounts of an energy consumption and fuel on the basic and auxiliary engineering procedures of production of products, performance of works, rendering services based on the set technological system. The Russian economy is one of the most power-intensive ...

Even if EU traditional agriculture is based on a considerable part on livestock enterprises activities, and many products are sustaining the traditional activities, livestock production is the largest source of greenhouse gases, high water usage, driver of deforestation, loss of biodiversity, land use, European Union (EU) is the biggest food importer and the second food exporter, spend around 40% of its budget on Common Agricultural Policy in detriment of other sectors. This paper work aims to emphasize the impact...

The magnetorheological (MR) fluids include ferromagnetic and paramagnetic particles suspensions with sizes included between 0.03 and 10 ?m, located in a carrier fluid (usually mineral oil). The complex fluid viscosity strong depends of magnetic field applied. Each particle can be considered a small magnet, which tends to align in the direction of the magnetic field. The magnetorheological fluids have the ability to change their viscosity when they are introduced into a magnetic field, due to the aligned particles ...
