  • The line-start permanent magnet synchronous motor has a high efficiency and an advantage in constant speed operation regardless of the effect of load variation. However it is difficult to predict the performance of characteristics accurately, because of the unbalanced starting torque with the initial starting position of the rotor and the generation of a break torque. In this paper the dynamic characteristics of the line-start permanent magnet synchronous motor are described and compared with those of the squirrel-cage induction motor through the simulation to find the characteristics of the permanent magnets and the rotor bars in the line-start permanent magnet synchronous motor.

  • The toxicity of GX-12, a naked DNA vaccine developed by research team of Dong-A Pharmaceutical Company, Green Cross Company and Genexine for the treatment of HIV infection, was investigated in Sprague-Dawley rats. In single-dose intramuscular/oral acute toxicity studies, animals were treated 0, 250, 1000 or 4000 $\mu\textrm{g}$/kg/$m\ell$ in sodium phosphate buffer.(omitted)
