Recent experiments have shown, that PPSB (factor IX-concentrate) derived from ß-propiolactone/ultraviolet (ß-PL/UV)-treated (cold sterilized)plasma is not infectious in chimpanzees in respect to hepatitis B and Non A-Non B. To answer the question whether the B-PL/UV treatment influences the tolerance and efficacy of the cold sterilized PPSB- concentrate, long term application of PPSB-Biotest was performed in chimpanzees.After 12 applications of 25 units factor IX/kg in weekly intervals no signs of intolerance were observed by means of skintesting and observation of blood pressure during i.v. application. Determination of coagulation factor activity during the application period shows the same factor IX- recovery at the beginning and at the end of the study.
This paper deals with the design and tests of an internal permanent magnet synchronous machine with 12 slots and 10 poles. The machine is analysed under no load condition to estimate the flux linkage and the electromotive force as well as under load condition to calculate the iron core losses, the permanent magnet losses and the output power by utilizing the transient finite element analysis. Several simulation results under no load condition e.g. open circuit voltage and under load condition e.g. torque are compared with those of the experiment to validate the electromagnetic simulation model and to investigate the machine's characteristics. Streszczenie: W artykule opisano projekt I badania silnika synchronicznego z magnesami trwałymi z 12 szczelinami I 10 biegunami. Silnik analizowano w stanie jałowym w celu określenia strumienia magnetycznego oraz pod obciążeniem w celu określenia strat i mocy wyjściowej. Przeprowadzono symulację I wyniki porównano z danymi eksperymentalnymi. Analiza metodą elementów skończonych oraz badania silnika synchronicznego o magnesach trwałych przeznaczonego do zastosowania w pojeździe kolejowym
