As a result of the high aggressiveness circulating water, there is problem corrosive destruction heat exchangers and reduction their working capacity at industrial enterprises both civil military purposes. The article deals with issue increasing anti-corrosion protection steel surfaces (St3 Steel 20) by introducing an effective environmentally safe corrosion inhibitor MG-CHDTU into water compos...

OBJECTIVES The 2 primary objectives of this publication are to provide a practical step-by-step procedure for the ClariVein system and a focused literature review of endovenous ablation. MATERIALS AND METHODS The ClariVein system is the first venous ablation technique to employ a hybrid (dual-injury) technique built into 1 catheter-based delivery system. Endomechanical abrasion is produced by...

  The effect of magnetic field on an incompressible (Kuvshiniski-Type) viscoelastic rotating fluid heated from below in porous medium is considered. For the case of stationary convection, magnetic field and medium permeability have both stabilizing and destabilizing effect on the thermal convection under some conditions whereas rotation has a stabilizing effect on the thermal convection. In the...
