Defining the possibility of resonant modes onset in power supply systems (PSS) is a relevant task in selection and validation of VAR compensators (VC). At the current resonance negative consequences take place: supplemental heating of conducting parts, overload with the consequent outage of static capacitor batteries (SCB), excessive heat of transformer windings and a core. Existing practices to determine...
A correct definition of mode parameters is of great importance for examination of power quality indices under non-sinusoidal modes, these parameters being effective values of current, voltage, active and reactive power. A wavelet transform is a later method of digital signal processing. This method enables information about signal to be saved both in amplitude-frequency and time space. The technique...
Experimental investigations of the kinetics of penetration of stainless steel in TIG and A-TIG welding, and theoretical analysis of thermal, electromagnetic and hydrodynamic processes occurring in the weld pool metal were conducted. The stationary arc welding process was chosen as the focus of investigation, in order to study physical-metallurgical peculiarities of metal penetration in TIG and A-TIG...
Ballistic transfection, based on cell and tissue bombardment by the tungsten and gold microparticles covered with the gene DNA, was used for the delivery of a bacterial β-galactosidase and a full-length cDNA copy of the human dystrophin genes into mouse skeletal muscles. CMV-lacZ, SV40-lacZ, LTR-lacZneo and full-length cDNA dystrophin (pDMD-1, approximately 16 kb) in eukaryotic expression vector pJ...
