recommendations! Published in 2019 at "Frontiers in Energy"

DOI: 10.1007/s11708-018-0584-9

Abstract: It is difficult to predict the ignition delay times for fuels with the two-stage ignition tendency because of the existence of the nonlinear negative temperature coefficient (NTC) phenomenon at low temperature regimes. In this paper,… read more here.

DOI: 10.1021/acs.energyfuels.8b02443

Abstract: Pressurized oxy-fuel combustion is regarded as a new generation of oxy-fuel technology. The ignition delay times of methane in an O2/N2 atmosphere (0.21O2 + 0.79N2) and an O2/CO2 atmosphere (0.21O2 + 0.79CO2) were measured in… read more here.

Abstract: Összefoglaló. Bevezetés: Myocardialis infarktus esetén a panasz kezdetétől az ér megnyitásáig eltelt idő prognosztikus jelentőségű, a legtöbb szívizom megmentésére az első órákban van lehetőség. A Nemzeti Szívinfarktus Regiszter alapján tudjuk, hogy hazánkban a teljes ischaemiás… read more here.
