Longitudinal collective modes of a bunched beam with a repulsive inductive impedance (the space charge below transition or the chamber inductance above it) are analytically described by means of reduction of the linearized Vlasov equation to a parameterless integral equation.For any multipolarity, the discrete part of the spectrum is found to consi
Abstract The shift from conventional power plants on transmission level to distributed energy resources in the distribution grids requires procedures to enable efficient and economic reactive power exchange across different voltage levels.In this paper, we propose a multi-level reactive power market that enables reactive power provision from distri
Herbicide residues in soils can affect the cultivation of crops.The effect of cattle manure containing the active substance aminopyralid was investigated on field and vegetable crops: Potatoes (Solanum tuberosum), sugar beets (Beta vulgaris), maize (Zea mays), wild mustard (Sinapis arvensis), sunflower (Helianthus annuus), spring oilseed rape (Bras
Abstract Background PCR amplification of bacterial 16S rRNA genes provides the most comprehensive and flexible means of sampling bacterial communities.Sequence analysis of these cloned fragments can provide a qualitative and quantitative insight of the microbial population under scrutiny although this approach is not suited to large-scale screening
