Kohlenwasserstoffe,n. Sie machten der Welt bewußt, daß die Rohstoffe nicht unendlich lange reichen würden. Gerade bei den fossilen Energieträgern Erdöl und Erdgas würden die Vorräte bald zur Neige gehen, hieß es. Im Jahre 1970 schätzte man, daß in der Erdkruste noch Erdölvorräte mit einer Heizkraft von insgesamt 117 M

Modeling of Hysteresis Nonlinearity Based on Generalized Bouc-Wen Model for GMAe first time. The parameters of the models are optimized with Particle Swarm optimization (PSO) algorithm. The hysteresis loops of GMA are asymmetric, and the classical Bouc-Wen model can not describe such asymmetric hysteresis loops satisfactorily, but the generalized BoucWen model can describe asy

Fostering the Teaching of Cultural Vocabulary in EFL Contextscial contexts. Thus, vocabulary and cultural knowledge become crucial in foreign language learning, as speakers should be able to understand linguistic and cultural differences (Byram 1997), as well as cultural conceptualisations (Sharifian 2003, 2013). However, as previous research has stated, cult
