The global spread of 5th generation (5G) wireless systems causes some concern about health effects of millimeter waves (MMW).To investigate biological effects of local exposure to 5G-MMW on human body, a Mens Jackets novel 60 GHz band exposure setup was developed, and its performance was validated.A spatial synthetic beam-type exposure setup using
The article describes the choice features of the matrix elements of the calculation schemes of the metalware segments of the Cutting Boards bridge crane trolleys on the basis of the multipurpose layout drawing in various design cases.The general sequence of the structure formation of the calculation scheme matrix is shown.The article proposes the a
Flotation data on copper-bearing shale in aqueous solutions of inorganic electrolytes (NaCl, Na2SO4, KPF6, NH4Cl) and organic reagents (ethylamine, propylamine) as frothers were presented and discussed.The relationships between shale flotation, surface tension of aqueous solution and foam height during bubbling with air in the flotation system were
