Evaluation with micromagnetic methods of T22 and P92 steels microstructure modified by thermal treatment
PublicationOpisano rezultaty badań wywołanych obróbką cieplną zmian mikrostruktury na właściwości magnetosprężyste stali T22 oraz P92. Badano pętle histerezy amagnetycznej, polowy efekt Barkhausena (HBE) oraz emisję magnetoakustyczną (EMA). Wykazano, iż komplementarna analiza HBE oraz EMA (obwiednie natężenia i szybkości zliczania impulsów) pozwala na jakościową ocenę charakteru zmian mikrostruktury badanych materiałów.

Rational design, synthesis and biological evaluation of thiadiazinoacridines: a new class of antitumor agents.
PublicationZsyntetyzowano serię związków o potencjalnej zdolności do wiązania się z DNA z grupy tiadiazinoakrydyn poprzez cyklizację odpowiednich pochodnych 9-imino-4-nitro-9,10-dihydroakrydyny. Zbadano ich zdolność do wiązania się z DNA oraz cytotoksyczność względem kilku linii komórek nowotworwych. Badania aktywności przeciwnowotworowej wobec białaczki P388 wskazały na zgodność tych wyników z wynikami cytotoksyczności in vitro. Wykazano,...

Application of semi-Markov processes for evaluation of diesel engines reliability with regards to diagnostics
PublicationThe paper presents semi-Markov models of technical state transitions for diesel engines, useful for determination of their reliability, as a result of the conducted statistical empirical studies. Interpretation of technical states provided for this sort of engines refers to ship main engines, i.e. engines employed in propulsion systems of sea-going ships. The considerations recognize diesel engine as a diagnosed system (SDN), of...
