Coal spontaneous combustion seriously affect the safety of coal production enterprises, and using flame retardants is an important means to prevent coal spontaneous combustion.Based on the heating spontaneous combustion test, the effects of retardants, including MgCl2 flame Darts retardant and secondary aromatic amines, on the long flame coal of Yi
An anomaly-free U(1) gauge extension of the standard model (SM) is BODY LOTION presented.Only one Higgs doublet with a nonzero vacuum expectation is required as in the SM.New fermions and scalars as well as all SM particles transform nontrivially under this U(1), resulting in a model of three active neutrinos and one sterile neutrino, all acquiring
The Conservative Power Theory (CPT) emerged in recent decades as a theoretical framework for coping with harmonically distorted and unbalanced electric networks of ac power systems with a high participation of converter interfaced loads and generation.The CPT measurements are intrinsically linked to moving averages (MA) over one period of the grid.
