Two logics are implicationally equivalent if the axioms and inference rules of each imply the axioms of the other. Characterizing the inferential equivalences of various formulations of the sentential calculi is thus foundational to the study of logic. Using an automated deduction system, I show that Łukasiewicz's CN can be derived from the sentential calculus, here called GTL, of Hilbert/Acker...

Introduction In the last years there is a growing interest in the development and study of alternative fuels across various transport industries. Aviation industry is no exception to this trend. Indeed, the International Air Transport Association (IATA) established the importance of sustainable low-carbon alternative aviation drop-in fuels in their recent Technology Roadmap [1] in order to repl...

Since the inauguration of United Nations Sustainable Development Goals (UNSDGs), environmental performance and sustainability have become more important to decision makers, scientists leaders organizations than before. In response this, different spend all endeavors conserving resources ensuring sustainability. this context, transformational capacity ensure green their organization. The purpose...

Leadership style may affect nurses' performance directly it have positive or negative effects on nursing performance. We investigated relationship between transformational leadership (TL), job satisfaction, organizational commitment (OC) in Jordanian nurses.

Abstract Gas to liquid (GTL) process involves heterogeneous catalytic chemical reactions that convert synthesis gas to hydrocarbons and water vapor. A three phase reactor, called Low temperature Fischer-Tropsch (LTFT) is commonly applied for GTL process. In this reactor the gaseous phase includes the synthesis gas, light hydrocarbons and water vapor, the liquid phase is a mixture of the h...
